[Q] Stuck in bootloop after trying to install a custom ROM, unable to detect the device through ADB/Fastboot [Solved] - Samsung Galaxy A71 Questions & Answers

Title says it all. But for those that want to know a bit more in detail about what's going on, I tried to install this custom ROM: https://forum.xda-developers.com/t/rom-oneui-2-5-twrp-ncx-2-5-for-a71-sm-a715f.4174135/ Clearly I did something wrong (a bit more clarification in that guide would help people not used to rooting an Android device getting through that process easier), so now I want to go to square 1 by installing the stock ROM again. But the thing is, after installing multidisabler through TWRP, the phone is not permanently stuck into a bootloop and now I can't even go into safemode, nor download mode, and I can't enter the recovery mode, the only thing my phone is capable of doing is to restart by itself by holding the volume down and the power buttons at the same time, and now ADB nor Fastboot can't detect my device (the PC does a Samsung device being connected though, so it's not a hardbrick, I guess).

Samsung devices do not use Fastboot. You should restore through Odin instead.
Try the following:
1. Download Odin on your computer, you can get it from here. Extract it into a folder.
2. Download the firmware for your device. Find out your device model first and then look on http://samfw.com, I've downloaded from there a lot in the past, it works great.
3. Extract the firmware, you should get five files: AP, BL, CP, CSC, and HOME_CSC.
4. Make sure your device is powered off, and press power + volume down + bixby. You should be asked to confirm you want to enter download mode, press the volume up button.
5. Plug your device into the computer, then select the files for all the slots. Use CSC, not HOME_CSC for CSC (CSC is for fresh restore, HOME_CSC is for software update).
6. A device should show in the top bar, something like [COM:6]. This means your device is connected. If it isn't there, make sure your device is plugged in and in Download Mode.
7. Click flash. The firmware should start to flash and there should be a progress bar in Download Mode. Once it's finished your device should reboot into the system.

Well, trying to reflash everything through Odin has been a thing I tried to do, but how am I supposed to shutdown a phone that is stuck at the Samsung logo (is there any combination to shutdown a Samsung during the boot process?)? And even after that, how am I supposed to press "power + volume down + bixby" if both the power and bixby buttons are the same buttons?

I tried entering Download Mode hours ago, but to no avail. Even before flashing mutidisabler through TWRP (and thus, the phone was working), I had to use ADB in order to make my phone be able to enter Recovery Mode, since the combo for recovery and download mode just made my phone make a loud noise and restart my phone onto safe mode.

Ok, here's an update, apparently pressing those buttons, makes the screen have the same, but at least Odin recognizes the drive, but now I'm stuck at this error: "Complete(Write) operation failed."
Something's weird here, I'm 99.9% sure I did activate USB debugging for this phone, although that was just before wiping the entire drive before the phone got stuck in this loop.

Fixed. Many thanks to @hainguyenthao for helping me out ^^

I'm sorry to hear that you had trouble installing the ROM and I'm glad you were able to fix it.
I unfortunately can't see a way that I could make the tutorial on how to install the ROM any easier. I'm almost certain I covered all my bases going over the perquisites and how to install the ROM. I also have a Telegram group in that thread so that users can join if they are ever stuck in any of the steps so that either me or other users that have successfully installed the ROM can help people in doubt since I'm not available 100% of the time. If you ever decide to give it a try again, don't be shy, you can always join the group and request for help.

[Q] Help me!! My Captivate is a brick!!

My Captivate became the brick by failure of the recovery.
The screen remains black.
The power button and volume buttons no response.
In Japan, I cannot repair it.
I am not a member of AT&T.
Please teach it if know the shop repairing other than AT&T.
step one. get odin3 from http://forum.xda-developers.com/showthread.php?t=818439
step two install drivers if you dont already have the drivers on your computer, there are manual driver install tutorials online, google it
3. extract files and start odin.exe
4. put .pit file in the slot labled pit
5. put .tar file in the pda slot
6. plug usb data cable into computer, not into phone yet.
7. pull battery and put it back in,
8. hold volume up and volume down, insert data cable into phone and continue to hold the volume up+down buttons for at least 5 seconds. it should be in download mode. normally you have a yellow sign with a robot holding a shovel but i once had a black screen and odin still saw the device
odin will light up a box showing you are connected and the text should also indicate you are connected.
if not you may need to take other measures for download mode see here http://forum.xda-developers.com/showthread.php?t=829492&page=3
9. once you are in download and odin sees the phone hit start to flash the phone.
if the flash is not successful try to use http://forum.xda-developers.com/showthread.php?t=731989&highlight=odin+click+stock+rom+jf6 instead, master clear if at all possible
It is not a download mode.
Odin3 many times I used to change the ROM, all of which succeeded.
This time, ClockWorkMod Recovery in ROM from microSD installed, black screen freezes when it reboot.
From then on, things that can both download mode button.
Also, USB does not respond to the command prompt can also ADB.
Thank you.

try building the adapter in the thread i posted, supposedly it forces download mode. also it is posible to be in download mode with a screen that is black, it happened to me once, try to flash it anyway.
you might need to take a trip to akihabara to build the jig but it's worth it i think.
also if the phone starts to a black screen then master clear it with odin one-click on that screen.
thanks for the info. saved my phone. thanks
Thank you for giving good advice!!
Thank you for giving good advice.
I try a method of "jig".

Maybe not. I thought I was there too.
Keep trying the battery pull method. It took several times before it finally worked for me.
Here's one version:
http://forum.xda-developers.com/showpost.php?p=9024244&postcount=7
but you can try other button combinations (like just volume up, or just volume down).
If you don't see anything on your screen, that doesn't mean it hasn't worked. Sometimes the graphic for download mode gets screwed up so the screen will still be black, but ODIN will still recognize the phone.
If you really are hard bricked, then you need jtag service. MobileTechVideos can do it for you.

Make/buy a Jig (forces the phone in to Download mode) if that doesn't work then like startngate said you will need a Jtag to fix it.
thanks for the reply i took it into a samsung certified repair tech here in the city he has a jtag machine. odin wouldnt recognize my device at all

[q] galaxy s tweak app froze my phone

my phone has been frozen at the samsung i9000 screen ever since opening this app.... i am very new to this do not understand most concepts here.. ie. flashing a rom. If anyone can help me get my phone out of this state or has any suggestions on how i should fix this please comment.
if you can get into recovery mode try flasing another rom via cwm or flash it using odin and download mode (flashing non wipe roms via cwm might leave your apps and data intact)
What is the full name of the app? How did you try using it? Do you know what firmware version your phone is on?
First thing to try is turn off, remove battery sim and any microSD. leave five minutes and put all back in and turn on.

the app is galaxy s tweaks or something very simalar (black and white logo) the two options i was given in the app were "YES-BREAAAAK my phone" and "NO- Im not crazy" i selected no and then my phone just reset and wouldnt turn on again ive tried everything i can do without hooking up to a comp ( as far as i know) but thx for the advice
Where did you get this from? It does not seem to be in the market.
OK just found it. Have a read off all the comments. Not good.
http://www.appbrain.com/app/gst-(galaxy-s-tweaker)/com.pommedeterresautee.lagfix
You could try restart holding Home Vol up and Power button then choose Clear cache and Factory reset.
or
Try restart the phone holding home Vol down and press power button to get into recovery mode. then plug in and open Kies go to tools and firmware recovery.

Is telling me i need recovery code, I have never received one.
Just read this so it may work for you.
disconnect the phone from USB, pull the battery, replace it, boot into recovery mode and reconnect the phone. Go back to Kies and tools firmware recovery.
In other words repeat what you have done :-s
Original post on Android Forums.
The message indicated that I would need a recovery code that could be obtained later by clicking Tools | Firmware Emergency Recovery Menu.
I was then instructed to disconnect the phone, pull the battery, boot into recovery mode and reconnect the phone which I did. The phone would not reconnect. At this point I called Samsung tech support and wasn't impressed when I was simply told to repeat the procedure. But to my surprise, the upgrade was successful the second time around. Go figure! Anyway, I was wondering if anyone else ran into the recovery code message.

Broken Screen- unsure if rest of phone works

Hi,
A friend gave me their old i8190 which has a broken screen. They haden't used the phone in a while.
It makes a noise when I turn it on, and the softkeys light up, but the screen is broken.
However, when I plug it into the PC- it doesn't come up as a device.
I do not want to buy a replacement screen (cost around $70 US) to find out it's broken elsewhere.
How can I determine this- is there anyway to mirror what should be on the screen? The previous owner doesn't know
You can try to start it in download mode, flash the 3 button combo for recovery (and maybe a custom recovery), reboot in recovery and connect with adb. You will be able to browse the device internal memory and you'll know if cpu and ram works ok.
If you have a rom with usb debugging enabled by default you can run apps using adb (and take screenshots): http://stackoverflow.com/questions/4567904/how-to-start-an-application-using-android-adb-tools
Also check this: http://stackoverflow.com/questions/13326806/enable-usb-debugging-through-clockworkmod-with-adb

Well I'm a bit lost- I'm using the 3 button combo (Home+Volume up+ Power key). Is that combo correct?
Without being able to see my screen, how to I connect with adb?
It makes noises like my PC detects the device, but nothing comes up.
I do have special USB drivers for my I9310 installed- could they be conflicting or anything?
i8190 doesn't have the VolUp+Home+Power combination active by default. You have to start in download mode (VolDn+Home+Power, followed by VolUp) and use Odin to flash a patch to activate the combination for recovery (you'll find the patch here on the forum). If Odin doesn't detect your phone you probably have some other problems except the display.
After you flash the patch you can use VolUp+Home+Power to boot into recovery. When you are in recovery adb is active (even in stock recovery). Just type "adb devices" and you will see your phone.
I don't know about the drivers.

I keep trying the combo (VolDn+Home+Power, followed by VolUp) but it doesn't seem to show up in Odin. I don't need a patched Odin for it to work do I?
How long to I have to wait between VolDn+Home+Power & VolUp? And is VolUp by itself?
Sorry for the obvious question- but I've been trying for hours without any success.

You just need Samsung drivers for odin to detect your device, not sure if your special drivers is the problem, try downloading this one
Should be around 5 seconds, holding it any longer wont do anything so just continue holding if you're not sure, then just hit vol up only
Thanks for that.
It might be completely broken
I've tried two computers- installing the Samsung drivers, and using Odin, but the phone isn't showing up at all.
It's strange, because it sounds like it does work. I switched it on- and the volume buttons seem to make noises, and I even somehow took a photo.
What could be wrong? Thanks
I really don't want to throw this phone away.
Like I said- it seems to work (takes photo's) but nothing comes up when I plug it into any PC... I don't want to spend $100 on a new screen either, to find out it's broken.
Please help me out.

Yeah, it sounds like you should be able to connect it to odin. Have you tried different usb ports / different computers?
Remember to plugg cable to phone after key-combo.

[Q] Soft Brick issue

Hi,
First time working with a samsung phone, so im not very used to some samsung realted soft.
I'm doing a favor to a friend, he came to this problem where his phone woudnt boot up, He says one day he run out of battery and coudl never turn it on again.
when i turn it on, it gets stucked at boot image (first attached image), if i try to charge the battery image appears but with the loading logo (the loading logo is not moving), he told me that he also tried with another battery and the same appeared.
For what i've read there is a download mode besides recovery mode. I think i have no problem entering download mode (3rd pic), even though i don't know how to use it, pressing a button does nothing, and pluggin it to a pc (drivers installed it) seems the same.
So i wanted to enter recovery mode, and trying o factory reset it, but when i try to enter most of times nothing happens, the others i get weird screen like the one i attached.
I'm not pretty sure how to preceed now. The only thing that appears to be working is the download mode. If that's the case, how can i flahs the stock firmware on it?
Thanks for reading!

You would do the same thing as if it were custom firmware, goto http://www.sammobile.com/firmwares/, and download the stock firmware compatible with the device
Enter the device in download mode and flash the stock firmware with Odin
Instructions by SamMobile self:
Extract (unzip) the firmware file
Download Odin v3.09
Extract Odin zip-file
Open Odin v3.09
Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
Make sure re-partition is NOT ticked
Click the start button, sit back and wait a few minute

thanks for the reply, i think i might be doing something wrong, ODIN failed, i attach a screenshot, any idea?
I cannot tell much from the screenshot to be honest, all i can point at would be a newer version of Odin as the instructions told: [LINK TO ODIN 3.09]

Same error as before
im downloading some other firmwares to try, but i dont think there is the problem :s
I've been having this issue for months now. It does that exact thing. Try removing the SIM card and starting the phone as normal and see what happens. If it starts then, we have the exact problem. Mine works perfectly WITHOUT the SIM card but....what's a phone without a SIM card right? I've tried putting the Stock ROM on to no avail as well. I think my thread about this is still somewhere around but I doubt anyone managed to solve the problem either.
If you do work something out post it back. Sorry I couldn't be much help.

[GUIDE]Comprehensive T510 root guide

Warning:
Proceed with your own risk. I hold no responsibility if something goes wrong and you get killed.
Warranty void
KNOX tripped and some security feature won't be available
This guide based on @topjohnwu Magisk for Samsung. However, T510 is a bit different because it doesn't have Bixby button.
https://topjohnwu.github.io/Magisk/samsung
You need the latest Odin (I use 3.13). 3.12 or older won't work
***** NOTICE *****
Auto reboot must be disabled.
Download ROM matches your build number especially the last three characters. Unzip and only use AP and copy it to your tablet
Download ***special*** version Magisk Manager to your tablet and install it. "Install" Magisk using patch boot with AP file, and copy magisk_patched.tar to your host PC
https://raw.githubusercontent.com/topjohnwu/magisk_files/master/canary_builds/app-release.apk
Do not use normal Magisk to patch AP because it won't work
Bootloader Unlocked (read my guide)
Do not restore yet until this process is done.
STEPS:
1. Download your version of ROM. Make sure it matches your device Build Number
2. Unzip the ROM and copy AP to your tablet. Install Magisk Manager downloaded from link above. Normal Magisk Manager won't work.
3. Patch AP with Magisk Manager. The output file is "magisk_patched.tar". Copy the output file to your host computer.
4. Open Odin. Make sure Auto Reboot is disabled (unchecked)
5. Turn your tablet off. Press and hold Volume up and down buttons and connect your tablet to host computer. Press Volume up again to enter Download Mode.
6. Odin should show "Added". Locate your "magisk_patched.tar" and open as AP (it's AP after all). You don't have to flash others.
7. Wipe your tablet.
Disconnect your tablet.
Press and hold Power and Volume down.
As soon as the screen goes dark, immediately press and hold Power and Volume up until recovery screen appears.
Choose Factory Reset and press Power once, and confirm.
Reboot System Now
8. As soon as the screen turns dark, press and hold Power and Volume up buttons before screen shows bootloader warning. It will reboot again like brand new unit.
9. Do initial setup. Copy the Magisk Manager to your tablet and install if you don't see it
10. Setup internet connection and Magisk Manager will do some process, and it will reboot after it's done. You don't have to do button combo at this time.
11. Open Magisk Manager again to add other function including hide.
Your tablet should be rooted. However, here is something you should know.
Press Power button only: System with Magisk
[*]Press and hold Power and Volume up buttons before the screen shows bootloader warning and release: System with Magisk
Press and hold Power and Volume up buttons all the way: Stock recovery
That's it. Root is done.
***** IMPORTANT *****
If you want to do manual update, make sure you do steps 1-6 again. You don't have to wipe your tablet however.
Update: it appears "normal" Magisk (19.3) and Magisk Manager can simplify the entire rooting process.
Special instructions for Samsung is gone now.
Moreover, it appears normal boot can enter rooted system without button combo

I must not be understanding something, as no matter how I press Power and Volume Up, I end-up in recovery. Otherwise it boots without magisk installed.
If I release buttons when I see the Samsung logo, before the warning, I can then press volume up to continue with boot, and it opens recovery.
If I release buttons after I see the warning, the warning goes away in a flash and I still end-up in recovery.
If I release the buttons as soon as I see the Samsung logo, same thing.
Any suggestions?
I did all the steps again, strangely Magisk gave me a different patched.tar file.
Flashed the patched, but I noticed in Odin:
<ID:0/008> recovery.img
<ID:0/008> FAIL!
<ID:0/008>
<ID:0/008> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
I get a red message saying only official release binaries... The tablet is unlocked though... I must be missing something.
EDIT:
Now the tablet says an error has occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software. Can't even turn it off!
Smart Switch says 'Unsupported device' and device does not appear in the list for emergency recovery. Tablet appears soft-bricked
Finally Odin managed to flash it, after failing at first. Flashing stock now. Will start over.
It appears the latest Magisk and Manager simplified everything.
The latest Magisk (19.3) is "normal" version, so you may no longer need "canary". Moreover, special instructions for Samsung disappeared (click the link on the first post and it doesn't work).
I also noticed normal boot (just press power button with no combo) and boot into "root mode"

I followed the original guide and using the button combo to boot with Magisk. How do I move to normal boot? Magisk installed version is 19.4-c, and I just received version 7.3.0 of the manager. Should I simply (re-)install Magisk 19.4-c to get normal boot?

I will show you a screen cap later on because I don't carry it to work.
I used the "canary" build Manager and the root.zip
Now the root.zip is normal while Manager build number is still different.
As I mentioned on the edited post, the special instructions is gone, so it's possible topjohn has figured out solution for Samsung and integrated.
Yes, I boot it "normal" way and root is 100%
Noob Question
Hello and thanks for that guide!
There is (at least for now) one question:
Where do I get the stock ROM from?

You can find them on sammobile or samfrew
Thanks for this guide but I think I didn't do something right.
----------------
Reboot System Now
8. As soon as the screen turns dark, press and hold Power and Volume up buttons before screen shows bootloader warning. It will reboot again like brand new unit.
----------------
At this part, just after the factory reset, I reboot system and then I press Power and Vol+, but it goes again to Recovery. It never reboots like "brand new unit". It will always show the warning at start. Perhaps I misunderstood this part somehow.

When you press Power and Vol+ the warning will only flash, that's when you need to release the buttons. If you keep pressing it goes in recovery. I had a hard time figuring this out.

Thanks!
I just tried releasing the buttons just afther the "warning flash". Then it showed up again. After initial settings and Magisk installation, again that screen.
I'll try to start from scratch with another T510 and report back as soon as I can. Thanks again.
I'm pretty sure rebooting to recovery with volume up and power is still needed on every boot. The link for Samsung devices has just been moved.

Thanks for the guide.
Can someone confirm if i reboot, what do i have to press to keep it in root mode.?
So far the only way I've been able to do it, is to press power and volume up button and release when it flashes.
Root keeps disappearing unless I press combination of buttons.
Is there anyway to keep in root mode without pressing buttons?

I believe this is the only method at the moment.
Thank you very much for the rooting method, after unlocking the bootlader and rooting I have expanded my ram and now my tablet works flawlessly
Has anyone had any luck using Odin on Linux? I'm using JOdin Casual on Linux Mint and it seems like the process hangs while sending the patched image to the tablet, I also tried using my Windows 10 VM, and it seems to just get stuck after hitting start in Odin

Hey there, thank you for your guide!
I had a little problem when flashing with Odin though.
The tablet starts downloading, but when it gets to vbmeta.img, it shows the error "Custom Binary(VBMETA) Blocked by OEM Lock"
Before flashing, I disabled OEM Lock in the Developer Settings, but it did not help.
Any ideas would be greatly appreciated. Thx again!

I'm hitting a roadblock here, as well. I haven't tried using JOdin because I've seen discussions stating that you need 1.4.2 of Heimdall to flash these tablets, so I built that from source (JOdin includes 1.4.0). I unlocked the tablet, then patched the firmware with Magisk. Now I'm not sure what to do next.
Heimdall has its own package structure (which I'll read tonight), so it won't flash the AP file like Odin. It looks like it requires individually flashing each segment of the AP archive directly, and I really don't want to do that without some input from someone who can confirm that will work.
I'm acting based on this thread, on [RECOVERY][UNOFFICIAL] TWRP 3.3.1 for 2019 Galaxy Tab A 10.1 [SM-T510] and the Magisk install by patching file instructions.
Do I really need to extract each piece of the TAR per these instructions?
Also, the instructions to install TWRP here don't state that rooting must be done first, but based on the whole workflow, it seems it is required because this process flashes to AP and Magisk uses a stock AP when patching. It seems the work for TWRP would be obliterated by the Magisk root process.
Can anybody clear this up?

I honestly gave up trying to do this whole process on Linux, so I made a virtual machine with windows, made sure all my USB stuff was correct and used the official ODIN, worked like a charm
