By Following this guide, you will lose your warranty so keep that in mind before you begin. (Although you have probably already lost your warranty by unlocking the bootloader)
So, if like me, you ended up buying the Redmi Note 10S because it was very cheap (it's something like 200$ for a really good phone) and then just hopped on to xda forums for the latest roms and stuff, you'll find that not much development is going on regarding this phone, understandably because of "better" alternatives within the same line-up.
As a consequence, we don't yet have TWRP or CWM or any such custom recoveries built for this specific device (Redmi Note 10S) nor do I think they're coming any time soon, which is unfortunate since that would have made the process a tad bit more convenient. We don't have any custom roms built specifically for our device either (although we can probably use GSI roms)
So we'll now try to do the process ourselves.
Now, for the disclaimer:
DISCLAIMER: I'm an amateur in terms of tinkering with android stuff and phones in general. The process mentioned below has worked on my phone but I would still recommend waiting for someone more....knowledgeable to weigh in his/her opinions. If you end up bricking your phone or if things go wrong, I'm not responsible, that's on you.
Also, please read the entire guide first and then begin.
Alright, with the appetizers out of the way, let's just crack on to the main course:
STEP-0: Requirements:
Redmi Note 10S
Install OEM fastboot drivers
Obtain android platform-tools along with knowledge about how to use it
Your Bootloader should be unlocked (wait for 1 week after first attempt at unlocking after which you'll receive your "permission")
Fastboot rom from here
Magisk apk
Being ready to lose your data (in short, don't personalize your phone just yet (....and also take a backup of everything)) and accept that you'll have SafetyNet related issues until you do some other special stuff
Enable Developer mode and USB debugging
STEP-1: Obtain boot.img (and vbmeta.img)
What we need is a boot.img that we can patch using magisk. We can do some code-fu to pull it from the phone but we don't need to do that. We can instead obtain the fastboot rom from here (I don't think region matters but take accordingly just to stay safe). While downloading, you'll see that what you're downloading a zip. This is intended because the boot.img (and the vbmeta.img) is within this zip file.
Anyways, once you download it, unzip all of the contents into a folder and move on to the next step.
STEP-2: Patch the obtained boot.img:
Take the boot.img from the zip file you obtained earlier and move it into the internal storage of your phone. Install the Magisk Manager apk from here. Install the apk and then after opening, go straight to installing Magisk, then select "Select and Patch a File" and then select the boot.img that you moved into the internal storage. It will then start patching the boot.img after which it will generate a patched boot.img, the directory of which is mentioned at the end of the patching process.
Move the patched boot.img back into your computer and move on to the next step.
STEP-3: Flash the patched boot.img:
Alright, this is the final leg of the journey (or should I say, desserts?).
Keep the vbmeta.img and the patched boot.img handy as you will be needing them here. You can find the vbmeta.img in the zip file you extracted earlier in the guide.
NOTE: The vbmeta.img is especially important because if you don't flash this while disabling verity and verification, you'll be stuck in a bootloop until you flash the stock boot.img (the boot.img before you patched it) back because this.
Alright, with all of that at hand, boot your phone into fastboot mode.
Now disable what is equivalent to the windows version of secure boot:
Code:
fastboot.exe --disable-verity --disable-verification flash vbmeta vbmeta.img
And then the following command that will finish it off:
Code:
fastboot.exe flash boot patched_boot.img
If you get stuck in a bootloop (perhaps because incorrectly flashing vbmeta.img or anything else), flash the stock boot.img with the same command and try the process again
And then finally for the cherry on top:
Code:
fastboot.exe reboot
After all that is done, hopefully you will see the setup for MIUI. Complete it as you normally would, and after the setup, you will find the magisk manager preinstalled but it will have the placeholder android app logo. Open that and it will prompt you to complete the download and installation of magisk manager. Do that and then open magisk manager (at this point it will have the familiar logo), go straight to installing Magisk and then select Direct Install (Recommended) and then let it do its thing.
After that, it will prompt you to restart your device to complete some stuff at which point you have successfully rooted your phone.
Aftermath:
I would like to remind you that SafetyNet will fail, even if you enable MagiskHide. You will have to do some other stuff to fix that if you want to use stuff like Google Pay so if that is a deal breaker, I suggest you don't follow this guide yet until some recommendations regarding SafetyNet pop up in this thread (or if you find some stuff elsewhere (please do let me know)).
Weirdly the Widevine rating is still at L1 according to DRM Info so I guess Netflix and other stuff will work fine(?). I don't use netflix or prime video so I can't help you there.
Concluding:
If there is anything step I have missed out or some issues you're facing, please let me know within this thread. I'll be happy to resolve the issue. If there are any recommendations regarding SafetyNet or any recommendations in general, I'll be happy to listen.
EDIT 1: You can't use Netflix because you won't be able to find it in Google Play Store.
EDIT 2: You can use Netflix and other DRM protected applications by installing the following Magisk Modules:
Riru (This is required by the next one)
Universal SafetyNet Fix (To pass SafetyNet ctsProfile evaluation)
MagiskHide Props Config (!!MOST IMPORTANT!!) (To get fingerprint certificates and pass other authentication related stuff)
Of course, as is with software, this stuff may eventually be patched by google or netflix so you should still refrain from using this guide (or rooting in general) if you don't want to deal with the hiccups down the road.
Certification is still L1 (weirdly) after installation of the modules and you will now be able to find Netflix in the store.
EDIT 3: Edited the guide after @murigny64 's reply (Thanks!)
Hello
No need to flash both A and B,
you can use "fastboot flash boot patched_boot.img", it will flash active system branch
because "boot" is a "partition_by_name" and symlinked to active partition (boot_a or boot_b)
I can flash Boot & VBmeta without issues but "--disable-verity --disable-verification flash vbmeta vbmeta.img" command just does not work. I got vbmeta.img from original device image & i have tried all kind of versions of command "fastboot.exe --disable-verity --disable-verification flash vbmeta vbmeta.img". Flasching VBmeta vorks but then i guess i would need spesific modified image file where it is disabled already. Any advice?
flashing vbmeta does result in an error and boot loop.
Error: unknown option -- diable-verity
Okay it seems like my phone has been sort of rooted but not completely. When I tried to edit my build.prop (to disable MiraVision), it resulted in the entire build.prop being wiped completely.
Thanks for sharing
Anyone got Google Pay working after installing Magisk and Universal Safety Net Fix ?

Can you please outline the steps? perhaps I am missing something by mistake.
You haven't followed the guide above, you've sent the commands in the wrong order. If you have done it in the right order previously then your adb version is maybe out of date so follow this guide and try again:

Could you please tell me the right order in which the two command lines have to be entered?
I was able to successfully entered the two lines in the below order,
fastboot flash boot path to patched boot image
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot reboot
I am now seeing MIUI logo for more than 10 minutes. I am not sure if this waiting time is normal?
Could I try replacing the second line with fastboot flash vbmeta path to vbmeta image?
Your help will be highly appreciated.
In the exact same order as RandomAccessVemuri has kindly posted for us all in their guide above. The vbmeta file first then the boot.img. If everything is done to the letter then there's no reason it shouldn't work on your device.
It looks like you're trying to format one of the partitions after modifying the boot.img, that's the wrong way around, so yeah that's going to stop it from booting. And when the commands take it should take seconds, then on rebooting using the fastboot command it should load up in a normal time.

Hello,
I have done a factory reset to my phone and I lost something very important so is it possible to get back to the previous version of the phone before the reset or should I give up
And thanks for your answer
Hello, I have the same phone as u. I wanted to unlock my bootloader and I tried like every tutorial on Youtube and other websites i could found but none of them worked out for me. this ****ty outdatet program of xiaomi just dont recognize my phone. Pleaaase tell me how u did it
Is it possible to don't wipe userdata ? Maybe using flash_all_except_data_storage.bat ?
There is some options to set before root ? On some other tutorials they tell to turn off MIUI optimization for example
Gg
I want to root my phone but I am scared I hard brick it because I did it before but I was still under warranty and I somehow locked the bootloader so should I give it another shot or just forget it?

Okay so I got my oneplus 3t today and I updated it to Nougat via the ota file all good so far. I then decided that I wanted to install a custom rom so I downloaded twrp supersu etc everything needed to root and install the rom. Here's where it went wrong in knowingly I downloaded the wrong twrp flashed it and it would just hang at the flash screen for twrp. Anyway after hours of trying to install a recovery I managed to get a stock one to semi work, now it turns out I don't know how I did it but my phone won't even boot it just turns on and goes straight to fastboot mode. I managed to get a stock recovery semi working but it won't let me install the stock rom from internal storage and I've tried updating through adb and it will hang at a random percentage for a good 20 mins and then just fail. Really need some help here it would be great, thanks
Hi,
If you can get into fastboot mode then the best recourse is through there. Hope you properly OEM unlocked your device.
First of all, you MUST have the latest adb/fastboot binaries and FOR SURE have the correct drivers.
Follow the links on this XDA article to download the latest adb and fastboot binaries: https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads
This is the link for the Windows binary: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
Extract all the contents of the zip file in a folder on your PC.
Then, also make sure to have THE CORRECT twrp, 3.0.2.0 or 3.0.3.0. This is the link but currently it is down: https://twrp.me/devices/oneplus3t.html
Download THE IMAGE, NOT FLASHABLE ZIP and put it in the same folder as the android platform tools above.
Finally, download the latest complete 3T firmware from OnePlus from this link: http://downloads.oneplus.net/devices/oneplus-3t/
I STRONGLY recommend not to use an update zip, even a full ROM update zip as that one might not include certain firmware images.
Put THE ZIP on the same folder as the others, DO NOT EXTRACT ANYTHING.
On your PC, open a command prompt in the folder where you extracted the android platform tools and run the following: fastboot boot twrp-3.0.3-0-oneplus3t.img (assuming you downloaded the 3.0.3 version of twrp).
Your phone will TEMPORARILY accept the twrp recovery as a boot image and boot from there. NOTHING IS BEING PERMANENTLY WRITTEN AT THIS TIME.
After that, enter TWRP's Wipe menu and wipe system, data and cache.
Finally, use TWRP's Advanced menu and enter adb sideload mode. Once there slide that slider to the right to enable adb mode and return to your PC and enter the following command in the command prompt:
adb sideload OnePlus3TOxygen_28_OTA_029_all_1612131737_17e7161d2b234949.zip (assuming you downloaded the 3.5.4 binary from OnePlus).
TWRP should properly flash the OnePlus ROM and hopefully, return you to proper function. You can then update back to Nougat.
Hope that helped!
Yeah that sorted it thanks a lot

Once I do "fastboot boot twrp" and get a success, then what?
Do I need to somehow reboot the phone into TWRP - because that didn't happen on its own.
If so, how do I do this?

My instructions while detailed are not step-by-step. I expect the person reading them to have their PC configured correctly and at least a vague idea of what they're doing.
So, assuming you put the correct TWRP image (my command uses the name of the image for TWRP 3.0.3.0, you MUST alter it to reflect the actual image's filename if it's not that) on the same folder as the fastboot binary then yeah, the command
fastboot boot twrp-3.0.3-0-oneplus3t.img
should have made your phone reboot and enter into the TWRP image that you had on your PC.
If it didn't then you did sth else wrong before that.
Either you didn't OEM unlock your phone when you still could or you didn't use the android platform tools that I linked or you don't have the correct ADB drivers installed on your PC.
Start from there.
Hope that helped!
Thanks for your help @KeyperOS - I know where I went wrong...
To save some time, when I tried to reboot into TWRP, I typed "fastboot boot " then I dragged and dropped the TWRP img file onto that line in the cmd window (rather than typing the filename manually) - when you do that, it appears to include the full path to the img - it was that that was causing the problem.
When I typed the TWRP filename manually, it worked.
The only thing that caught me out was after I'd installed the ROM (via adb sideload) I tried to reboot the device from TWRP recovery - this seemed to just hang. In the end I just powered off the phone using the power key, then powered it back up as per usual.
Checked that the phone booted to the first of the setup screens, then powered off/booted into fastboot mode, relocked the bootloader and it seems to be OK.
I'm now back on 3.5.4 again, which was what I was trying to do...
4.0.0/1 had felt a bit laggy, and I'd sensed some issues with wifi and BT, I can now run 3.5.4 and see how it compares - was I just imagining it?
Thanks again for the guide and your help - I really appreciated it
@PugRallye
Windows' command prompt has an autocomplete feature. If you want it to add the name of a file, type a couple letters and then present TAB, it's gonna complete the filename itself and if it's the wrong file you can keep tapping tab to cycle through all the options.
Really glad it worked out Btw [emoji4]
In my experience, 3.5.4 was great but 4.0 is a step up in both battery life, which IME is amazing and features, with it I almost didn't need root and certainly don't need xposed which was a first.

Thank you so much for posting where you found this, this is exactly what I needed!!! You saved my tablet, it is much appreciated! :good:
Flashing Factory Image
The following instructions worked for me when trying to reflash the factory firmware for the ATT Asus MemoPad 7 LTE (ME375CL). I did originally try using the Asus Flash Tool and the raw firmware file (link below) but the tool said it could not unzip the package for some reason or another. So the steps below show how I did it using ADB with fastboot.
I ASSUME NO LIABILITY SHOULD THIS GO WRONG FOR YOU! However, it probably shouldn't matter if you are bricked, I doubt it will make it any worse Either way, I will not replace your tablet or be responsible for troubleshooting it should you mess it up more...
This scenario is based on the tablet stuck on the Asus boot screen and not going any further. I was trying some in depth rooting attempts and bricked it badly. I was then trying to install a custom recovery and that is why I could not reset it and bricked it.
PRE-REQS:
1. ADB installed - Download: https://drive.google.com/open?id=0B0fKccJIuWsna04wMjY1eG9YREU
2. Asus Drivers installed
3. Firmware - Download: https://drive.google.com/open?id=0B0fKccJIuWsnWGhwYzA0Vkluc2s (file is 1 Gb + in size, may take a bit)
SETUP:
If you already have a working ADB setup, do not download the one above. If you are using the one above, I extracted the folder into my C: drive, so the path for ADB would be C:\adb (to keep it simple and less typing).
MAKE SURE THE ASUS DRIVERS ARE INSTALLED! If you have plugged the tablet in to a pc before, they should already be there. Otherwise search, download and install the appropriate drivers.
INSTRUCTIONS:
Extract the firmware zip file to somewhere easily accessible like your desktop. In there, you should see the boot.img, recovery.img and system.img files, copy/paste those files to your ADB folder (for easier typing later on). There are also additional files like these but start with "unsigned_", do NOT use those!
1. Ensure you probably have at least 30% battery charge, I would still recommend more though.
2. Put the tablet in Fastboot mode by ensuring the tablet is completely powered down and then press/hold the VOLUME UP and POWER keys at the same time. When the Asus screen appears, let go of the POWER button but continue to hold the VOLUME UP button. Let go of the VOLUME UP button when the fastboot screen appears.
3. Plug the tablet in to the computer and then open a CMD prompt as administrator.
4. The following uses the ADB downloaded and placed in the folder as listed above, you may need to adjust the location path as needed if you already have ADB installed or located in a different path.
Type in the following without the quotes: "cd c:\adb" (this will change the path to the ADB files for the CMD prompt)
Type in the following without the quotes: "fastboot devices" (you should then see a device listed)
Type in the following without the quotes: "fastboot flash recovery recovery.img" (flashes the factory recovery image)
Type in the following without the quotes: "fastboot flash system system.img" (flashes the factory system image, may take a while to flash)
Type in the following without the quotes: "fastboot flash boot boot.img" (flashes the factory boot image)
5. Once those 3 images have been flashed, you should have seen a message that says "OKAY" after each one. You should be fine as long as you do not have any red error messages on your tablet.
Type in the following without the quotes: "fastboot reboot" (reboots device normally)
6. If all goes well, it should now boot to the Asus screen and then go to the ATT screen. If so, it will stay on the ATT screen for a while, just wait it out. Mine took about 12-15 minutes and then it opened to the new setup screen to set the tablet up as if its new!
This is how I was able to recover my bricked tablet, hopefully it can help someone else that may run into this.
John, thank you for the write-up. Just bought my ME375CL with 4.4.4.4.
When I try to flash the recovery partition, I get the following error:
C:\Users\Myself\Desktop\adb>fastboot flash recovery recovery.img

Click to collapse
and on the tablet's screen:
FASTBOOT CMD WAITING...

E:recovery flash failed!
FLASH FAILED!
RESULT: FAIL(flash_cmds error! )
Click to expand...
Click to collapse
I haven't tried the other commands for system.img or boot.img as I don't want to do anything out of order from the write-up. Ever run into this?
The firmware in the download is 5.1.1, not 4.4.4. That is probably the issue. If you are running good on that, I would try rooting it instead. If you are just wanting to upgrade, you will need to have an active AT&T SIM in the tablet to upgrade over the air. I am not sure if there is a flashable upgrade or not somewhere.
Oh ok John. I misread the title of the thread. I thought it was for updating from 4 to 5.
Quick question then: Is it possible, using the adb / fastboot tools, to backup the current 4.4.4.4 before I allow the tablet to update to Lollipop? After reading around, I understand that Lollipop can't be rooted but I have no real concern for it. But just in case I need the tablet to do something else in the future, I'd like to be able to return it to kit kat to be able to root.
Once you upgrade to lollipop, there is no downgrading for this tablet. There really is not much development for this device. I have kind of been working on a lollipop root when I can. Between my limited time and knowledge of android, I can't promise anything.
Overcoming red messages?
Dear John,
Thank you very much for your help. My device runs KitKat 4.4, I can't upgrade over the air, as I damaged my sim slot struggling to remove a stuck nano sim, which I had inserted before I realized that it required a micro sim. (I'd wrongly assumed that by now the world uses only nano).
I followed the steps above, which you wrote so clearly for lay men, thank you a lot.
The flash for recovery.img and system.img worked fine (no red error messages on device).
The flash for boot.img had a red error message.
Might you have an idea or workaround on how I can address this?
If it refuses, is it possible to factory reset?
Thank you very much again for any words of advice and kind regards.

Sounds odd that it did 2 out of 3 flashes. After you flashed those and rebooted, are you still on KitKat or did it actually update to Lollipop (5.1)? I ask because I assume the system image that flashed would be the operating system.
I still want to stress that this post is for recovering a bricked tablet that will not boot at all. I would not suggest using this as a flashing upgrade as I do not know if it will truly work. If you are still on KK (even after flashing) you could try installing the Asus Flash Tool and use the raw firmware that you downloaded and try it that way. It did not work for me so that is why I used fastboot. It might work for you.
Here is a link for the Asus Flash Tool:

As a follow up on your question above, Tab restart stalled at a screen (after the Asus logo), presenting some options to do recovery, reboot, factory reset, etc. (factory reset did not help), and red error messages at bottom.
To the GOOD news for anyone interested. I used the Asus Flash Tool and the firmware zip for 5.1.1 (many thanks for the advice).
Note: Tool did not install correctly on Win10 pc, citing error in installing some devcon.exe or similar file (guess that may be a firewall/antivirus issue).
Flash tool took some 15 or so mins unzipping firmware, after which I saw some action on the tab. Another 15 mins, and it rebooted to the At&t logo, stayed here for another 15 mins and unraveled a whole new device on Android 5.1
Glad to hear it worked for you and that I guess you can use this to flash upgrade from kitkat!
There is working way to root our device on lollipop! It is for the other Asus model, but it works for our
http://4pda.ru/forum/index.php?s=&showtopic=640814&view=findpost&p=53047686
I will check this out!
The root works, installed without any issues and verified with a root checker!
Here is a direct download from my Drive folder: https://drive.google.com/open?id=0B0fKccJIuWsnN21ZbnZpc2F6b1E
1. Download the file above.
2. Extract the zip contents.
3. Plug your ME375CL tablet in to pc via usb cable.
4. Make sure you have enabled Developer Mode and allowed USB Debugging first!
5. Open the folder you extracted and double click the "Root-One-Click.cmd" file.
6. It should reboot to fastboot mode and flash the needed files and then reboot again.
You should now have root access. Verify this by installing a root checker app from the play store. Keep in mind, it may say root not installed on the first run. Sometimes it will take a moment for superuser to initially run or prompt for access.
Side note: the root uninstall did not seem to work, got an error...but oh well, the point is to have root!
Thanks go to @little_pindos for finding this file...you are a rockstar!
Anyone get xposed on LP?
ATT Boot Up Sound
Tired of the ATT boot sound? If you used the rooting method above, then you can get rid of the annoying ATT startup sound by doing the following:
1. Install a Root Browser app (I recommend Rom Toolbox Pro, it has a built in file manager)
2. Navigate to the following path:
root/system/media
3. Find the file named "powerup.wav"
4. Simply rename the file by adding .bak to the end (ex - powerup.wav.bak)
5. Make sure it took the name change (some file managers have issues with that)
6. Reboot and see if it got rid of the sound!
You can also use your own startup sounds as long as they are in a .wav format, I believe. Make sure that the name of the file is powerup.wav.
You can also change your boot animation with "boot animation" app.
Best tweak IMO is adding "ro.config.low_ram=true" to build prop, or installing the low ram device xposed module if we can get it to work (both do the same thing). You gain about 100mb more free RAM on average.

AT&T removed the last update for this tablet months ago and no longer supports it. ASUS states AT&T has all the updates. Total cluster.
I couldn't find any guide for rooting the V40, so I thought I'd write down the steps I took to root my new EUR V40 - LMV405EBW. Maybe it will help others. Sorry if this is somewhat confusing, I didn't have time to make a polished version. It's basically made from my notes during the process with the commands copied from bash history.
-First, unlock the bootloader following LG's instructions here: https://developer.lge.com/resource/mobile/RetrieveBootloader.dev
There's no TWRP for the V40 and the one made for G7 doesn't work. I don't have the time and knowledge to even attempt to compile TWRP for the V40, so I proceeded with just patching an original boot image with Magisk.
You can get the patched boot images that I used from here:
Oreo 10e: boot_a_magisk_patched_10e.img
Oreo 20f: boot_a_magisk_patched_10f.img
Pie 20a: boot_a_magisk_patched_20a.img
Pie 20b: boot_a_magisk_patched_20b.img
Pie 20f: boot_a_magisk_patched_20f.img
Pie 20g: boot_a_magisk_patched_20g.img
Q 30b: boot_a_magisk_patched_30b.img (this requires flashing to the active boot partition).
Q 30c: boot_a_magisk_patched_30c.img (this requires flashing to the active boot partition)
Q 30d: boot_a_magisk_patched_30d.image (this may or may not work with "fastboot boot" and could require flashing to the active boot partition. I haven't tested if live boot still works. I just did fastboot flash boot_x img_file).
You can try to boot it with with fastboot if you have a LNV405EBW and skip the KDZ extraction part.
Installing Magisk:
Flashing this image isn't necessary, just straight boot should be sufficient and safe.
First install Magisk Manager 7 on the phone then connect the phone to the PC and run:
Code:
adb reboot bootloader
fastboot boot boot_a_magisk_patched_10e.img
After the phone boots the OS with the external boot image, open Magisk Manager and tap on Install. Select the option to Direct install to the active slot. I played it safe and decided to NOT flash also on the inactive slot. I've left it alone so I can use it in case of need of recovery.
You'll probably notice that you don't have a connection to the carrier. Just ignore it, it will back once the phone is booted normally.
Reboot and you will have permanent root until you switch the A/B slots.
In case my patched boot image doesn't work, you can just make your own.
Tools needed:
Magisk Manager 7.0.0 installed on the phone
LG Bridge installed on a Windows machine.
a Linux machine or VM (I used the latest ubuntu desktop), python3 with the zstandard module installed and kdztools from steadfasterX's repo. Maybe kdztools would work on Windows too, I haven't tried it.
adb, fastboot
You need to procure an original ROM file for your phone model. It can be downloaded easily with LG Bridge. Just connect the phone to a Windows PC, start LG bridge, go to the Software update tab and click on Update error recovery. Wait for the download to start and disconnect the phone. Ignore LG Bridge complains about not being able to flash after the downloading stage is completed. Don't click anything in Bridge and before closing it go to C:\Users\<your_username>\AppData\Local\LG Electronics\LG Bridge\SWUpgrade and copy your KDZ somewhere else. Preferably send it to the Linux VM to the LG work folder, it'll be needed there.
On Linux open a terminal:
Code:
cd ~/Documents
mkdir LG
cd LG
git clone https://github.com/steadfasterX/kdztools.git
cd kdztools
nano undz.py -c
For kdztools to be able to extract the V40 images, I needed to edit undz.py and comment the lines 88-90. So, this block should all be commented or undz will fail to extract the boot partitions.
Code:
#if len(dz_item['pad']) != 0:
# print("[!] Error: pad is not empty", file=sys.stderr)
# sys.exit(1)
To extract, with the KDZ copied to ~/Documents/LG/
Code:
cd ~/Documents/LG/kdztools
./unkdz.py -f ../V405EBW10e_00_OPEN_EU_DS_OP_0109.kdz -x
cd kdzextracted/
List the partitions contents and look for the IDs of boot_a and/or boot_b. In my case they were 44 for boot_a and 63 for boot_b
Code:
../undz.py -f V40510e_00.dz -l
Extract boot_a or boot_b or both, they're identical:
Code:
../undz.py -f V40510e_00.dz -s 44
../undz.py -f V40510e_00.dz -s 63
You can find the extracted boot images in the dzextracted subfolder. Get boot_a.image or boot_b.image or both from there and send them to the phone in a location accessible by Magisk Manager. The Download folder should do fine.
Open Magisk Manager and tap Install, select Patch Boot Image file and patch the image file(s) you extracted. Get the patched_boot.img that Magisk Manager saves in the Download folder and send it to a PC where you have adb and fastboot.
Go to the beginning of the post to the Installing Magisk section.
Damned tempting, but I'll wait until after Pie drops.

Glad to see this, hopefully it's a start for all of us.
If anything, at least a way to unlock the bootloader via legitimate channels! Gonna be generating that string, next chance I get, to be ready.

Once runningnak3d gets a hold of this, we should be good with the v40. Cool beans.
Hey do the unlock codes online work for $ 12-15 on sprint? I used to flash phones back in the day and got a great deal on a bad IMEI sprint lg v40, but so far I can see there isn’t a way yet. On top off all that I m in Europe and don’t want to get the error message that I m out of the Region. I would have to go to USA just to unlock the phone.
@runningnak3d
Can't I install the firmware on a different device?
V version can not unlock BL, so envious
Getting a boot image like that works but I find it stupid to not upload it so that the others don't have to do it. Besides only one model can be bl unlocked so there won't be any model mismatch (except firmware versions but keeping up with them is not that hard)

I recommend labeling the boot images with their firmware since future firmwares won't be able to run the same boot image but other than that I'm really sorry.

I mentioned in the description 1 line below the link that it's for 10e. There was no other update in a long time. I don't think there can be any confusion for now. I can edit and label the file when there's will be another fw update.
It looks like unlocking the bootloader breaks Widevine L1 on the V40 and downgrades is to L3. No more HD or UHD Netflix.
I couldn't find any other solution than to re-lock the bootloader to restore L1.
This doesn't happen on the V30.
@DLS123
Thank you for all!
I ask you for more details; i'm stuck at flashing first image in adb; it returns an error; have LMV405EBW with 10f. unlocked bootloader of course
Thx again for your support!
@daphix what do you mean by flashing the first image? You're not supposed to flash my patched boot image. Just boot it without flashing and Direct install Magisk from it with Magisk Manager.

Thx for answer; i not have too much experience in working with Magisk;
i just folowed your steps:
First install Magisk Manager 7 on the phone then connect the phone to the PC and run:
adb reboot bootloader
fastboot boot patched_boot_a.img
when i run fastboot comand for flash, is runing, but is returning "an error at line x"
i suppose is something wrong in this instructions.

Anyway; understand now what to do;
Steps are below:
- first install magisk manager
- download magisk zip from magisk site or from magisk manager himself on phone
- download patched_boot_a.img to phone from our good contributor
- use magisk manager and select inslall image of patched_boot_a.img from phone
- magisk manager will generate a magisk patched image
- transfer this magisk patched image (not patched_boot_a.img) to pc in ADB folder
- flash with Adb this magisk patched image from pc to phone.
Thx to our friend!

Whatver you're trying to do, is nowhere in the procedure I used. If you already booted with my boot image why are you making another boot image with Magisk and why are you trying to flash that? I never wrote anything of the sort.
if you booted with my patched image you already have temporary root and can use Magisk Manager to Direct install Magisk itself.

I tried many combinations of your commands;
maybe due that am noob, but succesion below simply is not working:

adb reboot bootloader
fastboot boot patched_boot_a.img
Anyone noticed that can't root with magisk the p20 pro or it just me?
Yes! There is a way to extract the boot image, use Magisk to patch it, then flash that boot image via fastboot. I'm actually waiting for someone with experience to advise on these items:
1. Can I extract the boot image from my phone directly? If so, can someone point me in the direction of the software to do so?
2. If I can't extract directly, do I need to use the update file from Firmware Finder that matches my current firmware exactly? I'm running B155, but there seems to be slight variations in the naming for some of the available firmware.
3. After I get all of this completed successfully, how do I verify that the image is good to use to avoid bricking the phone?
Thanks in advance to anyone that could help!

This guide has everything you should need. https://topjohnwu.github.io/Magisk/install.html
1. No, unless rooted
2. Find either the same FW you are on, or extract from a OTA.
3. Not sure on that one, it's always worked for me.

Thank you so much! Do you have any idea where I can get the OTA or at least figure out in specificity which OTA on Firmware Finder is correct? It sounds like it needs to be 100% exact to avoid issues / bricking.

OK... so I was able to extract the RAMDISK.IMG file but I can't patch it because Magisk Manager hangs after I install it. Is there a way to patch the RAMDISK.IMG file manually or via PC?
OK... so if anyone who is having trouble rooting... this is what I did to get root.
1. Be sure to download the firmware you are CURRENTLY on to avoid any possible issues.
2. Extract the RAMDISK.img file from the post above: https://topjohnwu.github.io/Magisk/install.html
3. Obtain a previously patched RAMDISK file to get an initial Magisk install on your phone first. There is one on XDA floating around named CLT-29-MAGISK.img.
4. Boot into FASTBOOT and then get to a CMD window with your ADB tools and use the command "fastboot flash ramdisk CLT-29-MAGSIK.img"
5. Reboot the phone and download Magisk Manager 5.5.5.
6. After installing Magisk Manager 5.5.5, install the next two upgraded versions while INSIDE Magisk Manager until you get to 7.1.x.x.
7. Click INSTALL on the Magisk option and let Magisk Manager patch your freshly extracted RAMDISK.img file from Step 2.
8. Copy that RAMDISK.img file to your PC.
9. Boot into FASTBOOT and then get to a CMD window with your ADB tools and use the command "fastboot flash ramdisk patched_boot.img"
10. Reboot and you'll have root!

Not sure why people struggle with this. The guy who started this thread has a copypasta guide he posted and could have followed. You should post your post in guide section for others I guess.

People struggle because the firmware is from 100 different regions, all with different release dates, there is no official TWRP that works 100% correctly with encryption, and Magisk changed the standard install method. I'm not surprised that people are having a tough time figuring out what to do so they don't brick their phone. This thing isn't cheap!
This is probably a dumb question... I have the Google store unlocked Pixel 4XL. I'm currently on the October factory image. I want to update to the December update.
Is there any reason I can't just dirty Flash the December update factory image and then use Magisk to patch the boot image from the factory update?
Or is there and easier way to get to the new update for unlocked Pixels that doesn't include the alternate method in the guide section of the forums?

Having an "unlocked" phone doesn't necessarily mean it is bootloader unlocked. Just wanted to confirm you are bootloader unlocked already. If yes, just d/l the December full image (make sure to get the RIGHT ONE) and edit the flash-all.bat to remove the wipe flag. You will lose root, but if you extract the boot.img from the image beforehand, patch it with Magisk Manager and put it in your adb folder before starting, you just run the script, boot back to fastboot and then flash the patched boot.img. May sound a bit complicated, but patching the image and pre-placing it before you start makes things go quicker. Good luck! :good:

Thanks for the reply. I can confirm that I have an unlocked bootloader.
Just as a point of frustration........
for the last 24 hours I've been fighting this issue with must be flashed in fastbootd... so, i download the new platform-tools... replace my existing platform-tools... all is good, right?
NOPE....
I have another platform-tools on my C: drive... that is assigned in my Path Variable... so it's trying to use the old platform tools... GRRRRR...
needless to say, i'm all fixed up now. Probably didn't have to stay up until 2:00am trying to get back to the October update...
So.. for those that need it, here are my exact steps for a bootloader unlocked Pixel 4XL bought from the Google Store:
1. Download full factory image from here: https://developers.google.com/android/images#coral (10.0.0 (QQ1B.191205.012.A1, Dec 2019))
2. Extract the zip file, open the zip inside of that extracted folder and copy the boot.img to your phone's Downloads folder.
2a. I used a usb cable to my PC and put the phone in File transfer / Android Auto to do this)
3. In Magisk Manager, click Install. Click Install again in the popup. Choose Select and Patch a File.
4. Find the boot.img that you copied to your phone's Download folder. Select it.
5. Copy the magisk_patched.img file from your phone's Download folder to the unzipped factory image folder.
5a. Refer to 2a above. You may have to disconnect the usb cable and reconnect. For some reason, my PC wasn't refreshing the folder with the patched file until I did this.
6. With your phone connected and in File transfer mode. Open a command prompt in the folder you unzipped the factory image to.
6a. You may be able to shift and right-click then click Open Command Prompt window here. That will open the command prompt at that exact folder instead of having to navigate to it through the command prompt. If you are a newer version of Windows 10, you may only see the Powershell option. I am not sure if Powershell will work. However, to get to a "command prompt" to be able to run the flash-all and fastboot commands. Simply type cmd and hit <enter>. Then you can use the adb, flash-all, and fastboot commands as explained below. ** WARNING: I DID NOT USE POWERSHELL, USE AT YOUR OWN RISK **
6b. Type adb reboot bootloader.
7. Remembering this is a dirty flash (i.e, keeping all of your data) edit the flash-all.bat file in any type of editor (even notepad). Look for the line that says fastboot -w update image-coral-qq1b.191205.012.a1.zip and remove the -w. So, the line just above echo Press any key to exit... should look like this:
7a. fastboot update image-coral-qq1b.191205.012.a1.zip
8. Wait for the flashing to finish and for your phone to reboot and fully boot back up.
9. Once it's connected, put your phone in File Transfer usb mode again.
10. Open a command prompt and type adb reboot bootloader
10a. See 6a
11. Once the phone is in fastboot mode, type fastboot flash boot magisk_patched.img
12. Once that is done, type adb reboot.
You should now be on the December update and rooted.
If you get the error that says "should be flashed in fastbootd", I can confirm that you do not have a new enough version of fastboot.exe. You can do one of two things. First, download the latest platform tools from here: https://developer.android.com/studio/releases/platform-tools
1. Either hunt down every copy of your platform-tools folder (I had multiple for some dumb reason) and consolidate to just one, then update your platform-tolls. Then update your system environment variables and point it to this new folder (making sure it's the only folder pointing to a platform-tools version).
2. Download the new version and copy the fastboot.exe and adb.exe directly into the folder with the flash-all.bat. This will guarantee you are using the correct version.
Hope this helps someone...

Just as a point of frustration........
for the last 24 hours I've been fighting this issue with must be flashed in fastbootd... so, i download the new platform-tools... replace my existing platform-tools... all is good, right?
NOPE....
I have another platform-tools on my C: drive... that is assigned in my Path Variable... so it's trying to use the old platform tools... GRRRRR...
needless to say, i'm all fixed up now. Probably didn't have to stay up until 2:00am trying to get back to the October update...

This happens more than you know. Glad you got it sorted. Next time (in a couple of weeks) it will be a snap.
