Back to stock after perm root: how?

I've got to sell my Sensation XE. I've done S-OFF, perm root, 4ext recovery, firmware update to install ICS by Android Revolution HD. Now I would like to delete perm root and install a stock rom, so the person that buy my phone can do OTA update without provlems. How can I achieve this? Thank you

Download Ruu on your computer , connect your phone to usb ,run RUU.
stock recovery image file needed
Hi, needing a bit of help here to restore stock recovery on my Sensation so I can catch OTA ICS update from Three uk. Phone is rooted with revolutionary custom recovery. I need a copy of image file for my software version: 1.45.771.5 so I can use Android Recovery Manager.
All help greatly appreciated!!!!
Any stock recovery should do the job, it doesn't matter whether it's from a 3 ROM or not.
Can your not stick the OTA .zip on your SD card and flash it via the custom recovery, though? I've done that via CWM on a couple of other phones.
Thanks for the reply Rusty, unfortunately had no luck using both methods you suggest, must be doing something wrong

revert back to stock to update to ICS

Hi , few months ago i rooted my phone ( did not install any custom rom) only the clockwork recovery mod (somethin like that) i think , so now i wanna go back to stock so i can install ICS, i download my RUU and a pg58IMG.zip file(what is that for) , so the problem is that my phone is connected in charging mod to my pc , and debugging is on , but adb devices cant read it , what should i do ?
Please any additional info would be appreciated , thank you alot
as far as i know, if you want to install stock htc ics, you just download the original RUU, run setup and plug in your phone, you don't need clockwork recovery or anything else like that, just follow the steps from the HTC RUU setup...
If you have received the FOTA updated just changed the recovery to stock HTC Recovery. And flash or run the OTA update. I use this guide to get back to stock HTC Recovery it may also help you [GUIDE] Get Stock Recovery/Install OTA Updates without losing data.

[Completed] TWRP Write protection preventing flashing / Backup's

I rooted / S-off and installed a custom ROM from day 1 with this phone (Verizon HTC One M8).
I have been using the phone for awhile and haven't flashed anything. Today, i started looking into upgrading to a new ROM and realized that I needed to update my firmware before hand. I used this to get back to stock with the new firmware - (http://forum.xda-developers.com/ver...ent/ruu-m8vzw-4-4-4-s-off-onlynewest-t2914914). I used the SD card and Hboot loaded the RUU from the 0P6BIMG.zip.
I am currently running this official software with s-off and root. I installed TWRP with flashify. I booted in to TWRP recovery and attempted a backup and it failed. I attempted to flash a new ROM (i verified the MD5) and it also failed. After some reading it seem as if the stock HTC kernel has write protection turned off preventing TWRP from accessing these files.
I think i will be fine if i get another ROM installed....The new ROM will have a kernel with write access. I would even be happy with replacing the kernel on the official ROM (therefore enabling write access).
I don't know, I'm stuck. Please help!!!

Yes, seems that you might be right.
Maybe flashing a cusom kernel will be enough to gain read/write access in TWRP recovery.
But first:
Are you on the latest TWRP version? (Check in the Verizon One (M8) Original Android Development > [RECOVERY][m8wlv] TWRP 2.8.3.0 touch recovery [2014-12-22] thread.) There was an update yesterday to v2.8.3.0.
The new version has updated support for latest SuperSu app. Check that you are on the latest SuperSU app (viw Play store) too.
If both versions (TWRP and SuperSU) are up-to-date and you still have the access issue, then you should try to flash a custom kernel.
Check this for available kernels: Verizon HTC One (M8) > Kernel.
And here is a discussion thread about ROMs and kernels for your device: Verizon One (M8) Q&A, Help & Troubleshooting > ROM's and kernel suggestions.
In case that you still have questions or need detailed help, please ask in the Verizon One (M8) Q&A, Help & Troubleshooting forum.
Thread closed and thank you.

HTC One M8 QL_UL (M8s) No OS installed HELP!

So two days ago i got this phone and just yeseterday i flashed the newly released recovery for the M8s and rooted it shortly after i was so stupid i tried to install a custom rom on the M8s, but what i didn't know was that the rom for the M8 isn't the same as for the M8s (QL_UL), i did make a backup backup through twrp but i don't think it's restoreable since i only backed up the system, data and recovery i believe, also the backup is stored on my computer.
