HELP with restoring my phone to stock for warrenty ASAP - One (M8) Q&A, Help & Troubleshooting

Hi all, I need send my m8 back to htc for warrenty repair. I bought it standard and unlocked bootloader and gained s-off. Also flashed twrp recovery and custom ROM. I network unlocked it myself using a zip you flash in hboot as it was on O2. The cid is 11111111 so finding a stock using the cidndoesnt help as I can't remember what cid it was before. Can anyone help please? Can i use any cid stock as i unlocked to any network? Thanks very much. Ashley.

Bit the bullet and give it a go myself.

So followed it word for word and its perfectly fine apart from wont boot in to recovery which doesnt bother me aslong as it looks normal. Also used fastboot oem writesecureflag 3 to get s-on now i can send back after i argue with them about the bootloader unlock on htcdev

If you have unlocked via HTCDev the this would have removed your CID in which case yes you should be able to flash the WWE RUU on a branded device.
If you have not unlocked and are still running stock then no it wont work.
Does HTCDev unlock remove CID? Unless it changed to 11111111 you still won't be able to flash an RUU AFAIK

It does indeed. It doesn't change it to 1111111 it completely removes it altogether.
I re locked the bootloader the other day and re-flashed the WWE RUU as im sending it back (screen flickering problem) and it worked with no issues.
Vodafone Australia
I am Vodafone Australia and unlocked my phone via HTCdev. I am also facing the same problem (screen flickering)and need to send it back. I have re-locked it. As you just said "I re locked the bootloader the other day and re-flashed the WWE RUU as im sending it back" can you please explain how did you re-flash the WWE RUU? steps or link?

You need to get the vodafone au ruu. General wwe releases will not work for you. Pretty sure the correct ruu is available in the dev section.
Can't link, posting from phone.

Stock RUU for 1.28 needed
Hi there
I have effectively killed my HTC one - I unlocked via htcdev and upgraded the recovery - fastboot shows the device id when running the command fastboot devices.
However I am now stuck in a boot loop where the phone only boots to hboot (following a failed boot.img flash) I have downgraded back to stock recovery and re locked but cant find the 1.28 RUU to recover the device (and I did try the RUU for 1.26 but it wouldnt install)
Once I updated te recovery i ran the fastboot boot boot.img command
This failed to progress past the 'htc quietly brilliant' flash screen.
I dont have the rom .zip saved on my internal memory on the phone - I was hoping to be able to push it to the /data/ partition however when I try this sdb returns no connected device.
Wonder if anyone can assist in either
a - returning to stock with a RUU for 1.28
or
b - advise how to flash the files I need onto the phone (it seems that the ROM isnt booting so I assume its from the point I install boot.img and beyond I need so help)
Unfortunately I cant get the phone to boot to copy files to the memory so need to work entirely in fastboot and adb (assuming adb wil recognise the handset)
Many thanks
Gurry

But relocking it puts it back so unless you were on HTC__001 you'd be back on the VODAP001 CID

[Q] Reverting back to stock and locking back the bootloader

I'm sending my HOX for repairs tomorrow.
My HOX is currently rooted.
I think it would be safer if i reverted back to stock and with a locked bootloader.
Do I just run the correct RUU?
How do I lock the bootloader?
u can relock ur bootloader. http://www.theandroidsoul.com/how-to-re-lock-htc-one-x-bootloader/
follow this guide to flash the RUU : http://forum.xda-developers.com/wik...ashing_a_RUU_to_completely_restore_your_phone
I relocked my oem any now there's a security problem.
Im now having bootloop at fastboot due to low battery.
I've tried http://forum.xda-developers.com/showthread.php?t=1609190 and many other solutions, but none work.
Help please.

How to unroot, lock bootloader and s-off for warranty return

Hi
I need to send my phone back for a warranty repair but I am confused about the exact steps to take.
My phone is currently S-OFF, rooted, has a TWRP recovery installed and has the latest Vodafone (VODAP001) stock rom installed.
What steps and in what order should I act in order to be left with a phone with a LOCKED boot loader (not RELOCKED/TAMPERED), unrooted and S-ON?
The instructions in a particular online link talk of locking the bootloader and then flashing an RUU but I can't find one for my Vodafone variant. (CID: VODAP001)
I have been going round in circles for the last few hours.
At one point I did lock the bootloader and then did the s-on but ended up in a boot loop to the bootloader - (probably because I forgot to unroot?)! Rescued it using the HTC Bootloader unlock code, reset and then rerunning Sunshine for S-OFF.
I can't seem to work out what to do without an RUU file.
Any help will be greatly appreciated.

[HELP] HTC 10 bootloop on Bootloader Mode

Hi everybody,
I'm sorry, I'm sure this question may be asked so much time, but after 1 hour searching I don't find anything usefull for me... (Maybe a keywork issue ?)
I don't know what I've done, but after I locked again the bootloader in order to flash on a RUU, I blocked my HTC 10 and can't boot on android again.
When I tried it the phone is only going to bootloader mode and don't want to get to my Os. I have TWRP and was on the custom LeeDroid 7.0.
I can't backup or do anything and while i try the dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota on the terminal, it won't work...
And I can't unlock again the phone, I've tried and it's "relocked".
Has someone have the same issues ? Really need your help ! :crying:
Thank you !
Why did you even lock the bootloader to flash a RUU? Is that mandatory? Sticking with Lee is always a better idea .
You might wanna try using a RUU.exe to get your OS back. What firmware and model do you currently have?

Yes it was lol...
But i've read that it was better to be on a locked bootloader to flash ruu :crying:
Yes, you need to lock the bootloader to flash an RUU.
Some people like custom roms, some want to go back to stock.
From the bootloader you can go to download mode and get the unlock token and try the process again to unlock, I would guess. Beyond that, I'm assuming the RUU screwed up somewhere. It is generally not possible to flash an RUU unless the phone matches the RUU's CID and MID parameters. And if it didnt work, the RUU wont have gotten far enough to do any damage.

I've re-unlocked the phone but it won't install the ruu but i think i've made the good RUU choice from the HTC website (was this one : on the website HTC us/support/htc-10-t-mobile/news/)
And i got an error 155 (ERROR UPDATING IMAGE) can't update your android phone.
But i've checked and i'm CID: T-MOB101 | MID: 2PS620000 on my HTC 10 ...

so you can't flash ruu with a unlocked bootloader?? thats odd...people use rru to get back to stock after running custom rom and you shouldn't lock bootloader with custom firmware bc it supposedly bricks you...or is download mode still operatable?
edit: i just flashed an ruu to check and can confirm ruu worked with unlocked bootloader and s-on.

Fair enough, advice I followed at the time suggested I relock bootloader to do an RUU. Being S-ON or OFF doesn't matter.
However, since there was no RUU for my CID (H3G__001) I had to S-OFF in order to change my CID to WWE (HTC__001) to flash that RUU. My phones status at the time was S-OFF, Relocked. It worked fine. It also worked fine under those same conditions after I changed my CID to BS_US001 and MID to 2PS6500000.

Isn't the US MID 2PS650000?

The download mode works, bootloader too
I'm not able to flash with an unlocked or a locked bootloader, i've tried the RUU and the custom ROM like Leedroid for example.

I don't think it's the US MID, my IMEI is German and the phone works great on 4G / LTE in France (where I live) and i've read that 4G won't work with an US version in France, but maybe you're true and their is no RUU for my version ... (fragmentation pleasures).
Do you know how i can s-off this phone in order to change those CID which block me ? ^^' because i can't use sunshine bc no OS installed and can't flash one ...
In fact, the only think i can flash / unflash is TWRP and the recovery stock..

help!!! htc 10 bricked!!! can you write cid/mid while s=on?

I went from S=off to s=on in order to run a sprint RUU and I think i wrote the wrong MID and now im stuck in bootloader with out being able to install any ROM and also cant unlock the bootloader.
help!!!
Dont go stupid, can't do anything without an unlocked BL and S-OFF...... why on earth did you ditch s-off before solving problems.....
