[Q] [Solved] unrooting?

I've read around on the forums here and other places but some of it doesn't make any sense to me and I watched a YouTube video about unlocking the bootloader then rooting the phone unfortunately i didn't do a nandroid back up before rooting (using supersu) and i am wondering if it is possible to flash to a stock rom so that in the future i can ota update in the future.
here is what i have at the moment
international phone (im on o2 in the uk anyway)
android version: 5.0.2
Software number: 1.32.401.15
unlocked bootloader
rooted
s-off
SuperCID
Also if someone can guide me through this i would be extremely thankful.
Thanks for your help guys.

You would need to either get a nandroid of your particular carriers ROM, or download the correct RUU from HTC.

I have no idea, since you haven't told us what version your phone is. I think you ought to wait for feedback from someone else who can advise you better.

it's also easy to rename the RUU.zip to 0PJAIMG.ZIP, place it on a ext sd card formatted in FAT32 (a 16 or 32gig one should work), reboot into DOWNLOAD_MODE, agree and it should flash.

ok managed to flash it back successfully couple of things though:
i couldnt copy the file when it was named 0JAIMPG.ZIP to the sd card (was in the phone not sure if i had to take it out and put it on)
it still says "software status modified" "unlocked" "s-off" afaik you can't get software status back to normal, to get unlocked back to locked would mean me relocking the bootloader and s-off shouldnt matter with ota update?
if i was to now re-install twrp but before rooting i took a nandroid backup would this allow me to get ota updates if i then restore to that after rooting or would one of the things above prevent me?
if not is there anyway i can get ota updates again?

If you used the htc_fastboot to flash it will not reset the modified tag
you have to do it yourself >> http://forum.xda-developers.com/one-m9/general/how-to-restore-software-status-original-t3092882
To set unlocked to locked you have to do this >> http://forum.xda-developers.com/one-m9/general/how-to-lock-unlock-bootloader-htcdevs-t3092036
and yes, you can get OTA update with unlocked and s-off

Thank you so much for taking the time to help me out and providing links I am very grateful

Do I rename this file to fastboot.exe and delete the original fastboot?
I seem to always get the 90 pre-update FAIL when I flash different firmware.

Just leave it as htc_fastboot. They can coexist.
Dude, what's it tell you after you get the error 90? Flash again immediately, right? EVERYONE gets error 90 when flashing firmware. It's a pre-check before actually doing anything. If you're phone reboots to OS after getting 90, then just leave your command/terminal window open and put your phone back in download mode and re-run the exact same command to start the flash again.

That's what I have been doing.... Did not know EVERYONE gets that error. Thanks for the info though. From what I read elsewhere is that the htc_fastboot will reboot back into download mode instead of os. That's why I mentioned it.

I'm sorry to tell you but if you updated to 5.1 and did not go into developer options and check to allow bootloader unlock, and then locked your bootloader theirs is nothing you can do but flash a RUU. Are you s-off ? If no your most likely stuck.

Sir I am S-On. I am trying to flash a RUU but getting error everytime. Tried from SD card. tried via fastboot.
Also my M9 is HTC Asia (Hongkong). So I have tried flashing below one. Can I try flashing TW version given by you??

With S-ON it's not possible to downgrade or to flash RUUs that were made for other SKUs (Taiwan is 709 and Hongkong is 708). Since you can't use the RUU in my AFH folder because it's older than your actual firmware and there is no other RUU for the SKU 708 (or at least none I know) than that one you linked your only hope might be the RUU service on llabtoofer's website.
Edit @clsA: That file amit_coolcampus mentioned earlier is one of the OTAs for the Hongkong version of the M9.

Thanks Sir. Can I get this repaired if i visit HTC service center? Will they be having 2.11.708.30 RUU?

Honestly, I don't know. I've always been able to recover my phones without the help of the HTC service center or the RUU service. My guess is that the RUU service might be cheaper but that's only a guess. Maybe someone else here had to use one or both of these services and can share his/her experience...

Help restoring to stock

Hi I need some help returning to stock with a RUU.
My phone is currently S-off, rooted, twrp and supercid. I am trying to return to stock (keeping s-off and supercid). From reading posts it seemed like a simple task but I cant get it to work. I have tried two different RUU's. I have tried putting a RUU on my extsd and renamed it to 0PJAIMG.zip but nothing happens in download and it actually says SD NOT MOUNTED down the bottom left.
The other method I have tried is through ADB using these commands.
fastboot oem rebootRUU
fastboot flash zip 0PJAIMG.ZIP
fastboot oem rebootRUU puts it into a screen with the htc logo
fastboot flash zip 0PJAIMG.ZIP gives me the following message
C:\platform-toolsM9>fastboot flash zip 0PJAIMG.ZIP

Stock RUU
Hi, I recently unlocked the bootloader and installed TWRP. Since then I have done a backup and installed Android Revolution rom. No my phone continuously turns off and restarts.
I really want to return to stock but can only find limited information. I have a TWRP backup of the stock ROM but when I try to flash it in recovery I get "cannot restore system--mounted read only" Apparently the backup has to be flashed with fastboot however the instructions are a bit dodgy at the android soul
I have the backup copied onto C drive yet it's not in "system.emmc.win format" its " 2015-06-09--04-46-13_LRX22G_release-keys". This folder of course has a few files in it, such as
boot.emmc.win
boot.emmc.win.md5
data.ext4.win000
system.ext4.win000
system.ext4.winooo.md5
I tried looking for the right RUU but couldn't find any for Australia let alone Vodafone Australia. Can I use the UK one?
If anyone has any ideas or advice I'd be most grateful.
I'm really disappointed in how difficult this phone is to root/unlock and restore. I hate it. I hate HTC.

There's one for vodafone australia on Androidruu it's 1.32.710.16. It's actually really easy to return to stock once you know how. Have a look in other threads and use the sd card method. Just make sure its formatted the correct way.

Please don't blame HTC for your failure to read. You're describing a well-known conflict that results from running a 1.40 Rom on top of 1.32 firmware. There is a simple solution: Flash a 1.32 kernel or update your firmware.
And I don't understand your complaints about this being a difficult phone to mod. Compared to anything but a Nexus, it's a piece of cake.

Thanks for your help not....I don't understand why you're a condescending prick. Don't worry, I flashed another rom and all is good. Personally I found the galaxy S2 and S4 a lot easier than this. I thought this was a forum for help....if this is your idea of help, don't bother in future.

Well, I was a condescending prick, but this is also a common problem. If you try to run the latest ARHD over 1.32 firmware, you will get random reboots because there is a conflict between the old firmware and 1.40 kernels.

If you use sd card method the card needs to formatted to fat32 and make sure the file name has .zip at the end. If your using the adb method download https://www.androidfilehost.com/?fid=96042739161891970 and put it in your adb folder. Use htc_fastboot as the command instead of fastboot to flash the file.

Did you try the sd-card method? Rename the RUU to 0PJAIMG.zip, copy it into the root directory of a sd-card that is formatted to fat32 and not bigger than 32gb, put the card into your phone, boot into download mode and follow the instructions on the phone's screen. (Where did you actually get the 1.40.401.8 RUU? The sources I know provide the OTA update and not the RUU. So maybe you know a source I haven't heard of before.)
The output during relocking my old One S and/or my fathers One SV always stated the "too many links" error, too. Nevertheless the bootloader was always relocked after the reboot. (I've never relocked my M9 because there was no need to do so since I bought it.)
Fastboot boot recovery doesn't work on the M9. That's the reason why we need to grab the stock recovery from RUUs or OTAs instead of backing it up before we start flashing.
What TWRP version are you running? I think that error only existed in one of the older versions and is fixed in the newest one.
To replace TWRP with the stock recovery you can try this: Make a backup with only "recovery" checked. Rename the stock recovery to recovery.emmc.win. Replace the recovery.emmc.win in your TWRP backup with the renamed stock recovery and restore the backup. If you now reboot your phone TWRP will be replaced.

i'm running 2.8.7.0 twrp and neither the sd card method nor backup method worked for me, and bootloader is still unlocked with that output, twrp just says failed when i try and do a backup, and reboots when i try to flash a rom, do you think the phones memory is corrupted or something?, i just cant seem to do anything

There is a newer version (2.8.7.1-CPTB-B1) which can be found in the beta version section here. Furthermore there is a stock backup provided in this thread that corresponds to your firmware version. Try to update TWRP and then to restore the backup.
Edit (Just to answer my own question from my previous post): The second Link provides a 1.40.401.8 RUU, too.

Fastboot boot recovery doesn't work on the M9. That's the reason why we need to grab the stock recovery from RUUs or OTAs instead of backing it up before we start flashing.
What TWRP version are you running? I think that error only existed in one of the older versions and is fixed in the newest one.
To replace TWRP with the stock recovery you can try this: Make a backup with only "recovery" checked. Rename the stock recovery to recovery.emmc.win. Replace the recovery.emmc.win in your TWRP backup with the renamed stock recovery and restore the backup. If you now reboot your phone TWRP will be replaced.

Well, that definitely sounds like your phone's memory is corrupted. I don't know whether there is another method to help you than sending it to HTC's repair service. Are you sure your storage isn't just full (since the flashing output seems to be ok [see below])?

Decryption Unsuccessful and a bricked M9

hi
my GF phone suddenly displayed message and asked me to enter password to decrypt your data , and so i did. It then told me that my password was right, but the data was corrupt, and presented me a button to reset my phone. The button redirected me to recovery and automatically attempted to wipe /data and then re-mount it, but the wipe failed. I rebooted again with the same issue, same failed attempt to wipe. I went to install the zip again, and this time do a full wipe, but it was unable to mount my phone's storage nor my SD card. I am not able to mount either at all now.
the phone is s-on and locked , and i dont have any chance to unlock bootloader because oem unlock is turned off
is there anyway to repair partition and install a new rom without using any custom recovery ???

I assume a RUU could help you. Try this link.
Edit: Here you can find even more RUUs
Go to download mode and check your CID, that should help you know what RUU is correct for your device

The first thread you linked is outdated and the links are broken. Best solution would be looking at the sticky threads here in the general section.

if ruu doesnt work, go to download mode and try fastboot format <partition> . I think i had something similar and that was how I solved it.

For starters, charge your phone. I can't remember what the minimum threshold is, but there's a safety measure that requires a minimum battery level to avoid the phone turning off in the middle of delicate software operations.
You mention flashing the ruu via flashboot. Have you looked into applying the ruu via the SD card method? That may serve you better.

Can't Update Verizon HTC 10 to Android 7 Nougat

Hello everyone,
I have a factory HTC 10, Verizon phone. I'm running on Straight Talk so I don't get OTA updates, but I've updated with my laptop and Sync Manager before, so I know I can. So, I finally got the notification on Sync Manager that I could update my phone, from 6.0.1 Software # 1.85.605.9 to 7.0 S# 2.41.605.20. I go to update it add it stops at 19% and says that I have to low battery, I then charge it 100% and try again, but the same thing happens, the update stops at 19% and says my batteries to low.
Now, in my phone under About, the software # is 1.85.605.9, however when I boot to Download Mode my software # reads 2.41.605.20. And I confirmed this with Sync Manager, when my phone is normal booted and plugged in Sync Manager says my software # is 1.85.605.9. But when in Download Mode and plugged in Sync Manager reads 2.41.605.20.
I backed up my phone and did a Factory Data Reset, hoping that would help, but I still have the same problem. Can anyone help?
Thank you.

https://forum.xda-developers.com/verizon-htc-10/how-to/verizon-official-ruu-1-19-605-9-t3377586 here is the link to the latest official RUU for vzw.

Thank you.
I wanted to flash Nougat the first time that the upgrade failed but I couldn't find the RUU online at the time.
However, I still cant get the update to work. Following the directions from the link, I still cant get my phone to update.

Check the MD5 of your download vs the AFH download link. Make sure they match

I don't think you read the first post of the topic which holds the RUU! It's all explained there how to flash it. I would take the SDCard method. You can't "just" flash it.
Read the first post from the given link and it will be clear.
So take the RUU zip rename it and put it on the SD then boot into download mode and follow procedure

I always try to ask, just to make sure they aren't stuck or frustrated. It's hard being new, and having people flame respond all the time (as I'm sure you saw some of the previous comments)

Thanks everyone for assuming I'm an idiot that doesn't know how to read. I did try to load the RUU via the SD card, that didn't work either. Yes it was formatted to FAT32. The phone recognized the card but didn't detect the RUU. zip file.
Anyway, I haven't bothered since I've been busy and the phone is working.
Is there a reason why my phone says its running Nougat in Download mode, but is running Marshmallow when booted up?

sounds like firmware from nougat mixed with marshmallow OS. was the RUU.zip renamed to 2PS6IMG.zip?

If Nougat and Marshmallow did mix, could that have happened when my upgrade failed the first time? I tried renaming it a few things, I think I renamed it to 2PS6IMG.zip, but cant remember. Also, I tried to use my 128GB SD card, formatted it to FAT32, but I had to download a format software, as I could get Windows to format it natively, in File Explorer or Command line. Could the SD card be to large? I wanna try again, but I'm gonna get a smaller SD card to try.

What it says in download mode is your firmware version, what it says in settings > about is your ROM base (what the ROM you are running is based on)
Also, with the 10 you don't need to have your card formatted to FAT32. exFAT will work just fine. I would suggest you re-format to that and try again (128gb cards aren't made for FAT32). And make sure you haven't accidentally renamed it to 2PS6IMG.zip.zip (I've seen that mistake several times before).

Well, like I said I formatted to FAT32 because that's what aer0's tutorial said to do. I didn't think it would work with my 128GB, and I was worried I was going to corrupt it, but it didn't.
anyway, I'm going to get an 8GB SD card and try again, I'll format to FAT32 first just to try, then if it doesn't work I'll reformat to exFAT and go again.
I'll report back tonight.

well it worked, I'm running Nougat. I got a 16GB SD card, couldn't find an 8 at Walmart, was already formatted to FAT32, I loaded the .zip file on there from my computer and renamed it 2PS6IMG.zip. Flashed perfectly.
after I plugged it into Sync Manager just to see if it would recognize my phone, as I've trouble with that before. And turns out there's a new update. So, I tried to upgrade, to the new latest and it failed @ 19% again, with a battery to low warning. I had 90% battery. I just cant update my phone through Sync Manager I guess.
Thanks aer0 for the help. I think my problem was I wasn't renaming the zip file right or at all. I tried so many times I forgot exactly what I tried. anyway, I might be even more helpful to add to your tutorial to rename what ever zip a person downloads, they need to rename it to 2PS6IMG.zip. Because, I understood it as, download whichever 2PS6IMG_something.zip, drop it on the SD and go. Just might be more helpful.

I unfortunately don't have the hosting rights to those files. That's @Kisakuku and others. Have I thought about it, sure have... The only problem with renaming them all to what it should be is you lose tracking of the versions, with so many it's easy to do. What I have done is on my PC, I created a sub directory of all the RUU's, then renamed them appropriately within, so I can drag and drop to the SD. Also, with OCD, I have multiple 4gb SDs labelled with versions. Which RUU did you flash? .23 is the newest, shouldn't be a new release just yet.

I didn't mean for you to rename all the files, as you said no one could keep track of which version is which. I meant you should add a note in the instructions for the downloader to rename the file after they download the zip.
I flashed to .20, because I didn't know .23 was available until I connected to Sync Manager. So I tried to update though Sync Manager to .23 from .20, and it failed @ 19%

I updated the OP in the verizon RUU thread per your request sir

It was just a suggestion, but hopefully it helps others just as it did for me.
Again, I appreciate the help.
