[Q] HTC One 831C - Location India

Dear All,
Two days before , I brought the HTC One (32 GB Golden) which on digging the Phone identity came to know the Model no 831C, later after goggling it came to know that I belongs to Sprint Carrier.
On inserting the code of Hardware components, I found few test/s were not passed and worked normally, other issues are TV app is not recognizing the server, Double Tap Screen wake/sleep works depending on its mood, vDM Client error pops up often.
Request all the experts here to please help me out with the Solution as to how can I make it work flawlessly.
Regards
Karan Adhikari

1) Which tests didn't pass ?
2) Which ROM are you using ?
3) TV app is discontinued by HTC (HTC suggests "Peel Smart Remote")
4) Double Tap Screen Wake works only when you lift up phone and proximity is not blocked (5 seconds cooldown between trying again).
Double tap status bar sleep is buggy on lollipop (this can be different if you have custom kernel)
5) disable vDM client app to prevent popups (you should also disable other sprint apps like HtcSprintService and Self Service SZ)

First of all, thank you for addressing my query & sorry for delay in revert.
Sir, I do know it’s the Sprint phone, as far your concern on below questions, let me try to answer them as below:
1) Which tests didn't pass?
When I run the all functions test by this code (*#*#3424#*#*) in one of the test the error word in green / red appears on screen
2) Which ROM are you using?
I believe it’s the Custom ROM, which would have be provided by Sprint. Software no is 1.54.651.8
3) TV app is discontinued by HTC (HTC suggests "Peel Smart Remote")
No comments, will try to search the PSR on play store.
4) Double Tap Screen Wake works only when you lift up phone and proximity is not blocked (5 seconds cooldown between trying again).
Will strictly follow next time when I do it.
Double tap status bar sleep is buggy on lollipop (this can be different if you have custom kernel)
Its on Android KK 4.4.2
5) disable vDM client app to prevent popups (you should also disable other sprint apps like HtcSprintService and Self Service SZ)
I didn’t find the option to disable vDM app nor did I found other apps of sprint. May I request you to suggest any alternates for it ?
Now, sir my other query is Is it advisable to flash a latest LP rom (i.e Goggle play edition or the rom developed by Bad boys team here) , also it seems that I am S-ON, because when I enter the bootload screen Power + Vol Down key where three android icon at bottom appears , I read LOCKED at the very top of the screen.
Pl. suggest whether it shall be advisable to do it if so request you to suggest the best ROM which shall run flawless in India.
Thanking you in anticipation.
Regards
Karan

Can somebody help me out with this please.. ??
The snapshots of my device are attached hereby, my only query is, and considering the attached images of device can I flash a Custom ROM on to it? Will that be advisable to do so? Are there the chances to Brick the device.
If the answer according to all the Experts here lies in assertive, which ROM is best, since this is a Sprint Device, I have found on the forum that Badboyz rom shall go flawless with any Sprint device, so may I go ahead with it. I am in India presently so wish that all the apps i.e Remote TV, Radio should run properly.

You need to delete the second and third pictures, there is way to much personal information in there.
The "Locked" at the top of the screen in the bootloader means that the bootloader is locked. If you look directly underneath it you'll see that it says "S-Off". To flash custom recoveries or roms or anything, you need the bootloader unlocked. You can do this using HTCDev, or since you're soff, you can unlock it via adb.
Once you're bootloader is unlocked, you should be set for everything. Flash a custom recovery like Captain Throwback's custom TWRP, get root if you don't have it already, update your firmware, etc. The bad boys xda page has most of this stuff in it.
Note: Your phone is supercid, so you're not limited to just sprint roms.
---------- Post added at 10:31 AM ---------- Previous post was at 10:04 AM ----------
Also, just wondering what exactly were the tests that failed when you did *#*#3424#*#* ?

Thanks a lot sir, I am grateful to you, I have followed you instruction of deleting the images.
Now, last night I did the Factory Hard reset (P+V-DN keys), it went fine, except the data was erased which I never wanted to be backed up though I was haunting of loosing the Sim Lock, but all went fine.
I have my registration on HTCDEV too, and the process of obtaining the TOKENID should go without any hassles.
Now in pursuant to your advise below, will it still be mandatory to unlock the bootloader ? or I may follow the process of wipe/data and then immediately flash the BB's Rom ?
Further, I stand corrected that all the function tests are passed normally, it was my mistake of not placing the Handset on the plain surface while performing one of the test.
Finally, why the model no in phone identity says 831C, and not M8 - May I request your views on this please?
Thanking you once again for addressing, all you guys are rocking, I am here on this forum since 2008, and needless to say "A Proud Member"
All my Best wishes to MEMBERS.

Yes, you still need to unlock the bootloader. After that you need to flash a custom recovery.
After doing these two you will be able to flash a custom rom, just make sure you follow all the instructions on the BB rom page

Hi ssantos132,
I found there is a SuperSU app preinstalled on my Handset, which prompts me to Grant access when I try to install some other apps from PS- goggle, is my device rooted, because I have found in this link (http://blog.laptopmag.com/root-htc-one-m8), wherein lastly the SuperSU app gets installed automatically.
Pl. guide.
Thanks

Yeah, it looks like you already have root. Try downloading a root checker app from the play store if you want to make sure.

Well thanks for replying. I did that earlier, it says Congratulation your device is rooted. So now when we have concluded that my device is Rooted, the only thing left to be done is, flashing a Custom recovery thru TRWP or CWM right ? Incase if its already been rooted and say if I re-do it, any risk for Device?
Pl. guide.

Yeah, once the bootloader is unlocked you can flash a custom recovery then a rom. You can't flash a custom recovery through TWRP or CWM though. Download a custom recovery then use fastboot flash recovery recovery recovery.img

Believe me, That is one rare cellphone you have got.
I am having the same and as I tried few roms, without backing up the radio and replaced it with some random one. Now my phone is just a toy to play with.
I ll suggest you to stick with the rom you are having right now, Take a nandroid backup of the rom, radio and everything else. and keep it safe for future. You will never be able to find them online for this particular phone.
If you would like to help me solve my phone's issue, Please upload the radio. My phone is just laying around in my desk as I have no way to get it to work.

I know about these devices that are being sold in India. I bought a used phone on OLX having same model number with the exact similar problems. I assume these devices are development only devices which don't run a final version of software. I have noticed that most of the issues in the phone are software related. Using my development expertise, I was able to fix most of the problems and upgrade the firmware to Lollipop, however I have messed up the radio and was unable to restore the radio firmware to anything that actually works (This phones come with a radio version that can't be obtained from any online source). If you can provide the radio image from your device, I will prepare a flashable zip to upgrade the firmware to Lollipop which would include the modem you provide, along with instructions on how to unlock the device and flash it to get going. Probably this would iron out the issues that you are facing with your device.
To grab the radio image from your device, use the following command from "adb shell" or Terminal Emulator
Code:
$ su
# dd if=/dev/block/mmcblk0p20 of=/sdcard/radio.img
You will find a file in the sdcard (Internal) named radio.img. Please upload it and provide me with a link.
I would advice you not to make any changes to the device until I provide you with clear instructions on how to do so. Trust me, I really had a hard time with this phone.

Well thanks indeed for the time you took for replying, Sir are you from India Since the name sounds such ?
Secondly, I am desperately looking to upgrade the Software to Latest 5.02 Lollipop from present Kitkat, my basic requirement is that any ROM to which I flash should at least contain the Stock FM Radio, wherein it should be able to tune in the Indian Radio Station.
Confusing issues which keep me scratching my head is that I have pre installed SuperSU app in it. Also I re checked it via installing the app Root Checker which indicated that my device is Rooted. However as and when I tried my device to restart it in Recovery mode it starts normally after a while , the SuperSU app is not getting started.
Can you help me through please. Favor me with (1) Do I need to unlock the Bootloader ? (2) Do I need to flash the custom recovery thru TRWP or CWM ? (3) suggest best Rom which will working with FM Radio (4) A Layman's User Guide to carry out all the process.
Thank You once again.

(1) Do I need to unlock the Bootloader ?
YEs, you must unlock it. It won't affect the phone's basic functunalities
(2) Do I need to flash the custom recovery thru TRWP or CWM ?
Yes. I recommend twrp.
(3) suggest best Rom which will working with FM Radio
None for the phone we are using A Layman's User Guide to carry out all the process.
Please don't upgrade the rom as it might mess with the boot("radio") . Upload your radio and wait for Dhiru's post.

thanks, where shall I get the Radio file please ?

Required advice pl. help somebody
Pl. advise as on which TWRP img file should I take into consideration for flashing, since my boot loader is old one the firmware no 4096, Software no is 1.54.651.8, and its sprint 831C (HTC ONE m8). I yesterday tried with the the latest 2.80 twrp img file but got stuck on "Entering Recovery" Screen, some how could manage to come back by Power+Vol up and when the screen got black then Vol Down which took me to boot-loader and then came back by reseting phone. Now the phone is working normal.
I am desperately looking to install CWM or TWRP , so that can take an nandroid backup of the system file, and later post it for the experts here to update the firmware and fix other issues......
snaps of device are attached here
Request all experts to kindly guide me here on it.
Thanking you in anticipation

Canadian P20 Pro version CLT-L04, Questions about Magisk and bootloader unlock

Hi! I picked up my Canadian P20 Pro last week and couldn't be happier. It's been many years since I've owned a rootable device though and a lot has changed! I've done my best to read through all the guides for rooting the P20 Pro and it's only lead to further confusion as there seem to be many recent advancements. There seem to be a lot of different versions of this phone too. So I have some questions I'm hoping someone can answer easily! Let's assume my bootloader is already unlocked....
1) there's a really great guide on rooting the P20 Pro using All In One tool. But that requires flashing TWRP to achieve root using Magisk. I do not require TWRP as I only want root and do not wish to flash any roms.
a) is there a way to root with Magisk and NOT flash TWRP? I can't seem to find a straight answer on this...
b) failing that, can TWRP safely be removed and keep root afterward?
2) after unlocking the bootloader I was welcomed by a terrifyingly orange warning about my now 'unsafe' phone. I've read mixed things on hiding this. Is there currently a way to hide it?
3) how does the process work for OTA updates on an unlocked bootloader assuming there is no TWRP? I've read differing opinions on the necessity of flashing a no_check.img to the ramdisk and have no understanding of the new security checks on these phones. Can I run risk of bricking my phone through an automated update?
Ultimately I'm scared of forgetting TWRP is on my phone and accepting an update that'll brick it. Any information is welcome as are similar questions!

I am also curious if there is a good root process for this phone. Find anything yet?

I have a Canadian CLT-L04 that i rebranded and rooted to CLT-L29 with the guide on here.
https://forum.xda-developers.com/hu...de-how-to-root-debrand-remove-retail-t3788326
if you want better firmware compared to version 109 thats still on clt-l04 you can follow this guide, it worked well for me. (don't wait canadian OTA it'll take too long)
1) quite sure that TWRP is the easiest and safest way to root. Currently unaware of a better way to root the phone.
b) if you remove TWRP by flashing a stock recovery_ramdisk, root is kept. If you do an OTA though you might lose root.
2) thats here to stay i believe. Cannot find a way to hide it currently.
3)In this guide under the "install an OTA Stock Update: PC Method" you will find all the information you need.
cheers

I finally found the info I needed in this thread:
https://forum.xda-developers.com/hu...ide-getting-started-unlock-twrp-root-t3806180
Overall it was a very simple process and took less than an hour including reading. Once you've got your bootloader unlock code the all in one tool handles it from there. Unlock the bootloader, flash TWRP, reboot into TWRP, flash Magisk and you're done. You can flash the no_check file over TWRP if you want to be ready for updates but I decided to leave TWRP on for now. Loving having root on this phone so far!

On a different note, has anyone discovered any ROMs for this phone yet that can handle the notch? I almost tried Lineage until I found out there is no notch support. I've grown strangely fond of the thing for some reason lol

If you do a full backup of the L04 in TWRP before rebranding you should be able to go back to it easily at any time, just remember to save it somewhere safe other than the phone itself. If you've already flashed and are looking to go back you may find someone willing to share a stock backup if you ask around. But always best to do your own backup first, then you can go back whenever you like!

Anyone unlocked bootloader and rooted recently for the L04 model with 120(C792) Sept-2018 update?
Im scared to update before unlocking and rooting as the update might do something to fastboot etc. (this has happened to LG)
If not, then Ill update but if so, Ill just not update and unlock it as it is.

It's really easy to update once you've unlocked, I would suggest unlocking first if you have concerns. I have an L04 as well and just updated to 120 with no problems.

Hey, Thanks djparent, I unlocked and updated as you suggested.
Everything working properly, just need to root/twrp etc. now.
Thnaks again

No problem, glad it worked for you. I've soft bricked and recovered my phone a few times now experimenting so if you run into any problems I'm happy to help! Lots to learn with the P20.

I have a CLT-L04 8.1.0.136 C69 with October security patch from Mexico I want to rebrand it to CLT- L29 to get wifi calling and get rid of all the bloatware. Could I use this tutorial from dladz's tutorial:

One of the notes mentions the following: I) ]NOTE*** If you are on a later firmware than 120, please do not attempt this guide!!
I have only rooted one phone before in my life so I am no expert. I do no want to mess up my phone becuse it is the only one that I have. Also If I unlock the boot loader and rebrand can i get OTAs and the upcoming Pie release? Thanks for the help!

LineageOS 15.1 on L04
I installed LineageOS 15.1 on my L04 with out any issue. Some things to consider. USB-C will only charge the device, Titanium Backup will install but doesn't get root access and you'll miss the camera application.

Did you install it with a locked bootloader ? I really dont feel like paying for an unlock code. Would like to try Lineage though.

I do have an unlocked bootloader. Truth is i'm addicted to Rom's lol. That in mind I have tried every Rom, kernel, flash-able zip within this Forum and I can't brick this thing. L04 Canadian. Lineage is the best Rom for our device.
Roms that work:
- Lineage - Hauwei camera can be installed and works, dark mode works well.
------- Doesn't work: USB-C audio, NFC, RAW Option in the camera, Second ear piece as speaker, main speaker works well.
- First Ever Android 9 - Being the first build it works well. (Note: When I installed this rom I never installed the RemoveEncryption-P20Pro.zip) Seemed to work just fine without it. I did run it just because I wanted to see if it would brick my phone. It didn't.
-------Doesn't work: Dark mode, NFC, RAW Option in camera, Second ear piece as speaker, main speaker works well, seems to kill TWRP. eRecovery needed to get TWRP to function.
- AOSP 9 - Berkeley-Flex - Do Not Use...not ready.

------- Doesn't work: USB-C audio, NFC, RAW Option in the camera, Second ear piece as speaker, main speaker works well.
- First Ever Android 9 - Being the first build it works well. (Note: When I installed this rom I never installed the RemoveEncryption-P20Pro.zip) Seemed to work just fine without it. I did run it just because I wanted to see if it would brick my phone. It didn't.
-------Doesn't work: Dark mode, NFC, RAW Option in camera, Second ear piece as speaker, main speaker works well, seems to kill TWRP. eRecovery needed to get TWRP to function.
- AOSP 9 - Berkeley-Flex - Do Not Use...not ready.

What did you use to unlock your bootloader ? Funky ? Also I know what you mean I am addicted to Roms as well :laugh: Thanks for all the info I really appreciate it.

The great adventure of rooting the XZ1C

Hello everyone,
I have to say I am completely lost regarding the whole rooting process for the XZ1C. I usually manage to get where I want just by carefully reading the forums, but with this device, I feel overwhelmed by information. And I sometimes feel like what I am reading contradicts what I though I understood from previous reads...
I will try to sum up what I know so far.
First of all, I have a just-out-of-the-box Sony model G8441 with firmware 47.1.A.12.179 / Oreo 8.0.0 (never been connected to the outside world yet), and I want to properly root the device and install TWRP with no loss of feature.
What I think I understand:
To root, I first need to unlock the bootloader, which seems to be a trivial operation. However, this will break some functionalities due to DRM keys being erased. Once it is done, there is no way, ever, to get them back. There are however ways to "trick" DRM-related functionalities into believing DRM keys are still there.
Alternatively, there seems to be a way to backup the DRM keys prior to unlocking the BL, and this backup can somehow be reused and injected back into the unlocked device. If true, then this would certainly be a preferable method than the previous one, which would then be obsolete. However, it obviously doesn't look obsolete when I read the related topics, so I must be missing something...
Another thing I noted (but do not quite understand): There are ROMs for this device that "include" a DRM fix.
Last important thing I read: there is a paid "do-it-all" tool which takes my locked device and, with one click, makes it unlocked - rooted - DRM-fixed - TWRP-enabled. Now that sounds really good! Maybe too good?
As far as i know (but I learn new stuff every day on this topic) this DRM stuff is the main difficulty here. I understand that the rest of the process (root + TWRP) will be much simpler (although I'm old-school and completly missed all this magisk trend...!)
What I don't understand:
I read that some people downgrade to Oreo to be able to root properly, and at the same time, I read that Pie removed the restrictions on unlocked bootloader. So I still have no idea if I should connect and receive Sony updates, or avoid them.
Another thing I don't get, is how many ways do we have to root this thing? In the past, I was used to see, for a specific device, always one major and widly used rooting method. Here I fail to identify it...
What I think I will do:
1. Backup TA partition with j4nn's tool. This will probably imply flashing an older firmware right? Is there any link that could help me with this flashing process? (I only know Odin - did I mention old-school?) I saw this page for generic sony Z devices, but the thread is from 2013 and now closed. Is it still up-to-date or is there a newer thread?
2. Unlock bootloader and restore TA partition.
3. Wait for Sony updates? Or should I first hide unlock status?
3bis. Alternaltively to waiting for updates, maybe I can just flash the latest build? (47.2.A.8.24 if I am not mistaken)
4. Flash modpunk's TWRP.
5. Flash janjan's Boot.img to get root functionalities?
Alternaltively to all the above (except maybe step 1 that I will probably do in any case), buy the paid all-in-one tool (Xperifix), plug, click and wait... But will I really end up the same as with the manual way?
I saw a few other methods in the forums but it seems my brain is currently refusing to bring them back...
That's all I have right now. I would really appreciate if you guys could share some insight and tell me what you think about this, whether there are missing steps, useless steps, incorrectly ordered steps, silly steps, or if I'm just completely wrong about the whole thing.
Feel free also to correct me on the assumptions I made at the beginning.
Thank you very much for reading this repulsive piece of text.

By the looks of it you have done a great deal of research on the project.
Yes, go down the route of backing up your TA partition first, but that is not a small step in itself, it's pretty complicated and if you get that working then the rest of the project will be a breeze.
You don't say what version of firmware you want to end up on. If you want to end up on Pie then forget the DRMfix . But if you're staying on Oreo and can't be bothered with lots of files & flashing, then this is the easy way out, I bought the paid version and can verify it works.
More recently I ended up janjan's kernel (Oreo build). Hidden root (Google Pay works), lots of performance tweaks, DRM completely working.
It's unlikely that anyone will bother making a DRM fix for Pie as the camera works and there are only a couple of other features that get disabled.
It sounds like you're not the sort of person who's only going to read the first couple of pages of a thread (or the last) flash the xxxxxx and then complain when it's broken.
The people on the forum here are very helpful and if you go into any of the threads you mentioned in your post with a question, you'll get a reply.
Good luck.

I agree, there is a lot of information out there and different methods of achieving what you want - very confusing if you have not been following the threads since the beginning.
In my opinion, the preferred method is j4nn's method outlined here: https://forum.xda-developers.com/xp...devonly-exploits-temp-root-to-backup-t3795510
Use that post as your main guide (the final step in that guide, #13, is how you will achieve root). You will use Newflasher to flash the various firmwares along the way (this is linked from j4nn's procedure in step #2). User munted made a very detailed pdf file that fills in some of the details on j4nn's procedure - see the following post and download the pdf attached: https://forum.xda-developers.com/showpost.php?p=78255334&postcount=382
Most of the other methods out there came before j4nn's work - they didn't include DRM backup/restore.
If you follow j4nn's procedure, you won't need to use the janjan kernel as you assumed - janjan method is different and does not overlap with j4nn.

Sorry, I didn't point out that I was one of the early 'jumpers' who unlocked their bootloader without any backups, so I have been forced into always using fixes and all the information I have is based on having to fix your phone for it to work, but that's all changed now. I'm so out of date :-/
 @camaro322hp is right, if you follow j4nn's method correctly you'll be rooted with no DRM loss. All of the other stuff is not required.

Thank you Digesteve and camaro322hp for your help.
From what I understand the XZ1C didn't get as much love as other devices, thus there was a long period of tinkering before a "do-it-all guide" could be considered "the" solution. That could explain all these different approaches that are proposed. Like you said camaro322hp it's rather difficult to jump on this train, and I can only guess how interesting this ride has been.
Anyway, I didn't see that the TA backup thread from j4nn also encompassed all the information I needed; I am glad to finally know that there is indeed a centralized "do-it-all guide" . To make it easier for XZ1C newcomers, I think j4nn should update his opening post to make this clearer.
Since I managed to grab the attention of 2 XZ1C power users, I would like to ask you: Did you keep stock? Did you try alternative ROMs? Do you like some of them? Do you prefer Oreo or Pie?
For information, the most up-to-date experience I have on a Android phone is my LG90 with CyanogenMod 11 (KitKat 4.4.4! Yes sir!). I heard that it's becoming less and less useful to flash a custom ROM due to major OS improvements, but I would still enjoy the simplest and lightest Android possible.

SunJu22 said:

I've always been on stock, the camera is an important part of what I want from my phone and although there's lots of alternative camera apps, there's no competition to the stock camera app. Then I theme it black with swift installer and just uninstall or freeze any apps I don't want with Titanium Backup. I have stuck with Oreo, everything works perfect and I remember seeing so many people jumping to 9 then wanting to go back to 8 because they didn't like it. Something about changing the way the drop down menu works, among other things, but having never installed it, I'm not the person to comment on if it's any good or not.
I have been watching the XZ1c thread and Lineage is gaining ground, it even has a stock camera now. I would have thought something like that with miniGapps is going to be pretty lightweight and very similar to your carbon rom of before. At the moment this is based on 8, but is working well. Depends how keen you are to move to Pie.

Thank you Digesteve.
One thing I still don't understand. Part of the process is to hide unlock status. If I do this, FOTA will be applied and I will automatically end up on Pie, right? Should I skip this step if I want Oreo?
EDIT: when you say "a stock camera", you mean the Sony camera?

@SunJu22 I've stuck with the Sony ROM. A rooted stock ROM meets all my needs, so I've never felt the need to experiment with custom ROMs. There are some custom options out there that people seem fairly happy with, so if that's your thing, I'd encourage it.
Without going into too much detail, I'm still on Oreo for the moment, for a variety of reasons, but I don't know of anything that would keep me from recommending Pie.

One thing you should note is that once you unlock, there is no going back. AFAIK there is no known or working method to relock the bootloader.

Yes, I'm not entirely sure why having your rooted phone try and update itself is an advantage, but something I'd recomend avoiding.
Stock camera is the Sony camera, yes.

Thank you everyone, I believe I now have enough information to jump into this with confidence. The adventure begins, and will be reported in this thread for future reference, in the hope that it will help others like me!

Well, I am a bit sad... I wanted to report my "adventure" here in detail, but I'm afraid I have nothing to say.
Indeed, following the procedure from j4nn with a printed copy of munted's awesome guide, I managed to do all I wanted on the first attempt.
I don't have anything to add to this guide, everyone wanting to root their XZ1C can do it just by reading the opening post from j4nn and the mentioned guide. It takes a bit of time but nothing complicated thanks to the clear and detailed explanations.
I now have a fully functional rooted XZ1C (including camera) on Pie with Magisk root and TWRP.
Thank you all again from pointing me to the right direction.
I however have a slight disappointment. I wanted to start with Oreo and make an Nandroid backup before moving to Pie, but I didn't find Oreo builds on Xperifirm. So I jumped straight to Pie.
In case I want to test Oreo, I read that a downgrade is more complicated than an upgrade, but apart from the fact that a factory reset is needed for downgrade, I couldn't find an explanation for this. Any idea?
Last but not least: I looked for the latest Oreo build version number but couldn't find it. Do you guys know what it is and where I can download it?
I guess this will be all for this thread after this. Although it is very convenient to have my own thread to ask questions rather than finding the relevant page for each one, I don't want to annoy you too much...
EDIT: Please ignore the last question. I found out last Oreo build is 47.1.A.16.20, and I found the files via the download link in the opening post of the Lineage thread.

Hi, I've been thinking about rooting my XZ1c for a long time now. So, do I understand correctly that the ONLY disadvantage compared to non-rooted device is not possible to receive the OTA updates from Sony anymore?

No, you can flash a kernel to hide the bootloader unlock flag, this will mean that you will receive OTA updates, although depending on how you're rooted an update will most likely break your phone, so not that useful.

*made a thread*

Thanks--rooted withOUT adventure too
Very happily rooted now. Just wanted to say a quick thanks and add a few notes:
1. j4nn's renoroot to enable TA key backup and restore is fantastic. My advice: use and donate
2. munted's guide is excellent. clear and thorough...a rare combination.
3. do expect that renoroot may need to be restarted a couple of times. it took me 3 or 4 attempts to get temp root to pull the TA keys, although it took only 1 effort to get root back to restore.
4. topjohnwu's magisk is, of course, a key component to all this. Thx and $s there too.
I did a few things slightly differently/additionally than SunJu22.
5. I am on T-Mobile US, so I opted to create a hybrid Pie FW to get wifi calling and VoLTE. There are a number of discussions on this. I did it by combining the vendor**.sin and system**.sin files from custom-CH FW with the other files from custom-US FW. Of course (a) use IDENTICAL release numbers only, e.g. 47.A.2.10.28 w/ 47.A.2.10.28 and (b) you still need to delete .TA and persist files from the hybrid before you flash it.
Note: I don't really care about these features, but I have *heard* that T-mobile won't allow BYOD on their band-12 sites if they don't have VoLTE. Don't know if it is true (or where it is true) but figured why not?
6. I decided (for now, at least) to leave boot and recovery stock. So, I am using fastboot to run TWRP or a rooted kernel. Thanks again to j4nn for the method.
Note: I don't plan on allowing FOTA upgrades---I just like passing all the security checks and being able to *see* if updates are available.
That's all. Fine work in development and guides has made life simple and happy for me

Now riddle me this cause I'm on Tmo USA as well and I did the hybrid work fine as well but heres the question, does googlepay and banking apps still work with a unlocked bootloader or did you flash a modified kernel to hide the unlocked status.
Sitting on the fence about unlocking mine so I can do a full nandroid before trying out some gsi pie roms infact this is the first phone I haven't unlocked or least put twrp on since my samsung sidekick 4g o.o

kernel with hide-unlock

Full disclosure: I don't use Google pay or too many banking apps, so YMMV. But, I am using j4nn's kernel with unlock hidden. (See link in my note 6.) You can flash this, or you can leave in your stock kernel and merely fastboot to this. From what I have seen, it hides most - if not all -- indicators that the phone is rooted and the BL in unlocked.

Does somebody has :
G8441_1310-7123_47.1.A.16.20-R7B_Customized_CE1.ftf ?
Only backup i did not make, and its gone from XperiFirm.
Still have the feeling battery life was better in Oreo, and would be nice for experimenting.
Would be nice.
Thanks in advance.

Question Consequences installing custom ROM [SPES|SPESN]

Hello,
I would like to list the consequences of the changes when installing a custom rom on the redmi note 11 (spes/n).
In your opinion, what causes the following changes on our phone
This is some responses I can give after testing myself
1/ Unlock bootloader
Erase all your data
The unlock icon appears on the top of starting logo
2/ Install custom Recovery
Nothing have happened
3/ Install custom Rom (for me Evolution X)
First install : You will have to erase all your data
Upgrade : Nothing should happen
4/ Root
Maybe Unauthorizing Bank apk ?

Hi Darkspirit66,
Whilst I am not at the Custom Rom'ing stages yet with this phone, too new for me to tinker with this one... I'll just have to settle with me other phones for messing around with for now...
However I am glad you've raised these points. Whilst I've asked this before in another thread, its good to have clear answers...
Whilst most of the earlier questions, I kinda of expected. Some kind of message/logo at booting stage to announce it's unlocked/modified. I believe this is standard in pretty much all phones, one way or another.
Unlocking Bootloader/Flashing, again.... erasing of the data is standard practice again.
The bit that most concerns me... Is there any tell tale signs of after unlocking/rooting....? I've come from a mainly Samsung background. In the early phones, you simply ran "TriangleAway" and bob's ya uncle... no one is any of the wiser. Under new models, once ya trip the ole Knox, there's no going back. Permanent visible sign of tinkering, and security and bank apps will never work again without tricks.
So, if one was to unlock the Bootloader, root, rom and then change their mind and go back to stock. Will all the banking apps continue to work, or does it alter it for good....? I believe once unlocked and with custom recovery, its best to flash stock with TWRP as you get to keep the unlock but can flash stock and custom as much as you like without any triggers...??
Cheers, Lister

Hi LOS
Rooting the phone results in the problem with banking applications.
If you decide to unroot (it's possible) and reinstall a stock rom the apks should work again. (To confirm)

You can always hide root with magisk and keep your phone rooted also with banking apps ;-)

Question US Unlocked but using T-Mobile SIM - How to Root safely, many ??s

Long story, but after travails with an Amazon-purchased Oneplus 9 Pro due to it being locked (T-Mobile!) and them refusing to unlock it....
I went to OnePlus and got myself a OnePlus 10 Pro Unlocked. Still have the T-Mobile sim, though.
My question....
I have been out of the rooted phone scene for some time. I had a Oneplus 2 rooted and a Samsung Note 4 and 5 rooted. But things are different now, I'm gathering. Plus this is a new phone and I don't want to toss away hundreds of dollars by bricking it.
I used TWRP back in the day. Flashed many a custom rom back then. But with this OnePlus, I already unlocked it which... is that the same as rooting it? And what are the benefits of rooting / flashing roms vs just going with what is currently on this US phone (Oxygen 13 but not 13.1 yet)? I kinda want to see TWRP on here, and back up my whole set up into files I can then copy to my computer(s) for safety's sake. At least I liked that feature when I had it w/ the OP 2 and others.
Trying to get back up to speed in the world of rooting as it stands now.
Thanks.

TWRP on this device is really, "make of it what you will." It doesn't fully support this phone officially, and the leaked versions don't support device decryption, so you'll be forced to not use a passcode on your phone.
You don't need TWRP anymore, you just need to be careful and know what you're doing. There's guides for every model here, although they're all basically the same. Try to avoid flashing anything from your PC to the phone, just flash inside Magisk and BOOT images.
From my knowledge the reason for this is there's hidden partitions from OPPO all over the filesystem and normal flashers don't take this into account, anyone just trying to flash a full zip has bricked.
Which leads me to, there's no full recovery for this device that's free. If you brick a file and end up boot looping both slots, you're gonna have to pay for a restore. Even with TWRP, from what I hear, full backups sometimes fail to restore properly on this device.
TL;DR Be careful, read guides, you'll be fine. Rooting (on this device, with a lack of full recovery, hence no custom ROMs or Kernels) is really just used for audio mods, photo mods like free google photos, extensive app mods, etc. If you're not actively looking into any of these, stock Android is pretty solid.

Thanks for this.
I got as far as unlocking the phone and installing Magisk. But haven't gone further until I understand what the next step is.
Can I root non-destructively? Or is the phone wiped?

If you're unlocked and have Magisk installed, rooting is as easy as booting a patched boot image, then using Magisk to install it to your boot image. You have the choice of finding a matching one in one of the guides or pulling your own from a full zip.
It must match the firmware revision, I know for a fact personally that region matters little in case of NE2215/3, as you're only doing a one time boot.
I recommend @g96818 's guide here, you can find almost every firmware's boot image posted there if you prefer patch it yourself using Magisk or just boot an already patched one.

I have a 10 Pro (NE2215) rooted as a daily driver using TMO US.
Unlocked means 2 things in the android phone scene. Either it's carrier unlocked and can take any sim from any phone company or it bootloader unlocked which is needed to root and load custom roms.
There aren't any custom roms for the 10pro because of the lack of a full recovery system. Basically the ability to force full flash a stock rom in case the custom ROM soft bricks the phone. So that leaves rooting as the reason to unlock your bootloader.
I suggest reading the guide for rooting this phone, it's relatively easy. TWRP is unnecessary as it doesn't offer much without custom ROMs. Also you should back up everything on the phone that you don't want to lose because during the rooting process a factory reset will occur (android safety feature).
