Can'r unroot. - Desire 820 Q&A, Help & Troubleshooting

Hey guys, so i rooted my HTC Desire 820 a month ago, but i didn't actually needed. The problem started yesterday when I could update to Android lolipop and i couldn't, it kept taking me to TWRP. After a few hours of searching I managed to find stock recovery, flashed it and i thought thats it. Then the update still didn't work so i guessed it because of the root. So i went to SuperSu tu "Fully Unroot", but that didn't work aswell. Later tried Universal Unroot app- still rooted. Finally i used root browser to delete the su files and delete SuperSu.apk. It said it failed to delete SuperSu.apk, went back to check on the su files- they were back. So can you please help?!?!?

OTA 2.12.110.4, is it possible to install?

Hi,
I just noticed this was ready to download on my phone today. I downloaded and went to install, but the ClockWordMod Recovery doesn't let me install the update saying, "Image Verification Failed". I assume the problem is that the phone is rooted, and searching through the forums I heard this update isn't really anything big, just removing some German apps or something.
Is there anyway I can stop this update from notifying me? Or anyway to install? My phone is rooted but I'm not bothered about keeping it rooted as at the moment, there is nothing I need the phone to be rooted for. So, either way is fine for me.
Thanks!
If you want to unroot it, just flash generic ruu, more info here http://theunlockr.com/2010/06/07/how-to-unroot-the-htc-desire/
Than simply check for updates and update it
Or wait for few hours for rooted version of this rom
Hi!
I have a branded Desire and installed the update via Recovery. I had to disable the verification to do that (Goldcard inside). But all I got was a boot loop and my phone was derooted. I tried much (e.g. delete my data) and after a couple of hours I found the simple solution: Simply install the update again. Then I rooted my phone and restored the NANDROID Backup I made before I started the update because all of my data was gone.
Then I installed the Update again and this time it worked at the first time. All data was still there. I rooted it again and everything is fine. Don't know why my phone got a boot loop after first try but second try was perfect!
My suggestion: copy the zip from the download folder to the SDcard (made to a Goldcard!!!!) root and to the PC. Just if you need it more than once. Then make a Backup in the Bootloader. Then Install the update via Recovery. If anything goes wrong install the update again!

[Q] Lost root, won't come back

So I'm not a complete and utter n00b here, as I've been rooting and installing CM for at least three years now on several different phones. But this problem vexes me...
Patient: SIII, formerly rooted and running CM10.1 just fine. A few weeks ago, I tried to install a 10.2 stable build, and it somehow took my root away. I tried every trick I knew how - installing the root files via Odin (many versions), via ADB, via Kingo Root...nothing. Absolutely nothing I try will get this thing to give me my root back, and the ads are starting to really get on my nerves.
My ticker says 15 attempted installs, but I don't think it's blocking me from rooting...is it? All the phones I've rooted I've never had a problem like this, where absolutely nothing will allow root to "take", such as it is.
Any thoughts or suggestions?
Thanks!
Wow, nothing? I figured someone would at least sigh heavily, berate me for not reading the forums completely, then point me to a thread where this has been discussed ad nauseum
Last night, I tried rooting with TWRP, CWM, every variant and trick I could find to get this thing to root for me, and while these things all seem to load fine, none of them give me my root access back. No one has any ideas?
Thanks!
help
im using rooted 4.3 stock rom in t999..
everytime i boot into recovery it says "fixed root"
any solve for this?????
Did you dirty flash CM10.2 over CM10.1? if so, it might have failed to write the partition completely/correctly. I would suggest to backup everything that you can (adb backup or similar) and then wipe everything then reflash fresh CM10.2.0 + GApps + SuperSU or Koush's Superuser flashable zip.

SOLVED [Q] rerooting via recovery?

Never mind, it turned out that what she'd done was uninstall supersu, so reinstalling it from the market actually fixed things, after a reboot.
A not so techy friend whose tablet I had rooted somehow managed to unroot it. But TWRP is still installed and functional. We're about 600 miles apart, so I can't easily reroot it for her, and I spent 3 hours tonight trying to walk her through autoroot via chat, and it just will not work.
Is there a way to reroot via twrp?
She's on 4.3, build JSS15J.P600UEUBMK1

[Q] Quick question about stock recovery

Hello all, this is my first post. I'm looking for a little clarification on which stock recovery I should use so I can do OTA updates.
First, a little background. This is the first device that I've ever unlocked and rooted. I did a lot of reading before I started, but sometimes you don't really learn until you get your hands dirty. I started with an AT&T HTC One M8. I used HTCdev to unlock the bootloader, then used TWRP recovery. After that, I used Hasoon2000's All-in-one-toolkit for the Perm Root. All went as expected. I then loaded the Xposed framework and tried a couple of things with it. Suddenly, my phone started re-booting every 30 seconds or so. After panicking a bit, I figured out that there was a problem with the SuperSU. I re-applied that and all has been happy again. Since then, I also tried to obtain S-Off using the firewater method, but it failed with the Whelp message so I still only have S-On. I've now uninstalled the Xposed framework and I want to revert back to a stock recovery so I can do future OTA updates.
When I use getvar all, my version-main is blank. From what I have read, this is a common problem so I'm not worried about it. But, isn't this the number that I need to determine which stock recovery to use? Is this the same number that shows up in the Settings->About->Software information->Software number? Does the cid have any determination in which stock recovery to use?
After I do find the correct stock recovery, it is my understanding that I just flash that back to the device and it should be safe for OTA updates in the future. Is this correct?
Sorry... I'm a little gun shy after my reboot problem and I'm just looking for a little confirmation that I'm understanding things correctly before pulling the trigger again.
Thanks!
Ron

Yes you can go to software number to get the info you need. To do an OTA you need a stock sense ROM (NO CHANGES TO ANY SYSTEM APPS) you then need to flash the correct recovery for your software number and [IMPORTANT] relock the bootloader. You then can reboot into your system and take the OTA while still being able to unlock the bootloader and flash a custom recovery afterwards.
No need to relock the bootloader for an ota. People should stop spreading that info
Thanks for the replies!
Just to check my understanding, since I simply unlocked the bootloader, used the TWRP recovery, added SuperSU, installed then uninstalled Xposed framework, that means that I should still be on a stock sense ROM (with no changes to any system apps), right?
There is a lot to learn with all of this when you are first starting out. I'm reading a lot, but sometimes you do find conflicting information. I'd rather be a little cautious than do something stupid!
Thanks again!

Yup you're good ROM wise. Just flash the stock recovery and you should be good to go.
You can be unlock and have OTA.
You just need a stock recovery.
HTC ONE M8 fails to load up after failed software update
Hello guys, this is my first post. I really need your help as I'm at risk of loosing all my phone data. My phone internal memory had been exhausted and I bought an external SD card. I am unable to transfer data to the external SD card. I was doing a software update on my phone that failed to install, there was a warning sign on the phone screen for a few minutes then it try to power on but has failed, as it's seem to stuck on the screen that display htc powered by android. I tried the recovery holding down the power button and the column up button, the phone power off and back on but is still stuck on this screen (htc powered by android). I tried connecting the phone to my laptop to try and recover my data, but it's not mounting to the laptop. Please can someone help me. Thanks in advance.
Similar to the post above ie rooted and kept on stock. Also loaded a few Xposed modules but when I connected to my wifi I had over 30 updates so loaded all of them and once loaded the old bootloop started. I restored my nandroid backup from TWRP (this is an essential backup) and I was back in action. Phew!!!! I no longer had Xposed. So I did the updates again and the same thing happened. I am now updating one at a time which is painful when you've got so many. I also tried wiping the caches but that didn't work.
I noticed there were a lot of HTC apps eg HTC sense input, service pack, blinkfeed etc. I also notice a super SU update. ericksonlines post above said he had a problem with superSU. What kind of problem? What does he mean by reapplying? Flashing from TWRP?
So the big question. Which app(s) update did the damage???
Any apps I shouldn't update eg HTCs?
Has this happened to anyone else? What did you then do? Is the new updated superSU the problem
Apologies for cross posting on an Australian site but I'm a bit frazzled with all of this.

Hello! It is possible that an update came through that caused my phone to start into the boot loop. I'm not sure because it worked fine for a few hours before the problem started happening all of the sudden. My guess is that something updated that broke SuperSU. As soon as something would try to use SuperSU (or maybe the rights granted by SuperSU), the phone would crash and reboot. To fix the problem, I rebooted into the bootloader (TWRP) and re-installed SuperSU from there. After I re-installed, everything began working nicely again. I have not had a problem since and the problem occurred a few months ago now. I have also recently updated to the new version of SuperSU with no problems at all.
I hope this helps!

You're dead right Ron. Supersu was the culprit. Just simply updating from the playstore caused this. I restored an android backup which got me back. I went into the old SuperSu (V1.94) and clicked "clean up when updating from google play" or similar, did the update again (v 2.04 from google) and while this didn't cause rebooting, I couldn't install the binary. I chose "normal" (maybe I should have chosen TWRP) and it didn't work. So I flashed my old v1.94 from TWRP and that got me back. So some questions on updating SuperSu.
1. Is flashing the zip file through TWRP the best way to install a new version?
2. Should I delete or uninstall the old version or will flashing do that for me? Did you simply flash over the top of the other one?
3. Should I stick with 1.94, which works, or should I update to a new and improved version?
4. I think 2.16 is the latest. What version are you running, is it stable and do you recommend it ?
5. I assume I get the zip file from chainfire. They are way ahead of the google playstore for updates

I'm no expert, but I'm happy to share my experience. I do believe that flashing from TWRP is the best way to install. That is what I did to fix my reboot problems. I don't recall uninstalling the previous version in any way. I think the old file was still on there. I browsed to it in TWRP and installed it. I'm not sure what version I was on when I did this. Recently, a new update (2.16) was available that downloaded through the Play Store. When I went to update, it recommended that I use TWRP to install. I didn't go this route because I had already switched back to the default bootloader and didn't want to reinstall TWRP if I didn't have to. So, I just used the "normal" method. It updated successfully and I've had no problems. I am now running 2.16.

Thanks erick but given what's happened I don't think I'll ever update from the playstore again. I'll load 2.16 using TWRP and report back. I can't stress enough how important it is to have a nandroid backup. I reckon its the best reason to load a custom recovery. Its got me out of trouble twice now and gives me piece of mind. I've actually gone overboard on this and I have two backups on my phone which I have copied to my PC..

And stock ROM.
Updated to v 2.16. Piece of cake!!!
Loaded through TWRP, rebooted and that was it. It didn't even ask about installing the binary. Same binary I guess.
It worried me, however, when I saw over 700 pages on this version xda. Most with problems.

[Q] KF HD 7" Gen 1 - I seem to have lost root but still have TWRP

I can still get into TWRP,
I have the super user in settings and have allowed titanium back up although it says I do not have access to root.
I recently installed cynogenmod 12 from this thread. and it originally worked ( I had root access)!
The problem was when I downloaded Super su and updated the binaries, it went into a loop on the bootlogo. So I wiped and flashed again although now I had lost root access.
What can I do to get it back, or will I have to completely restart the process?
Thank you,
Jack.
