HTC One - stuck in bootloader/fastboot and no recovery

As you can see in the picture the phone boots up to this screen. A friend of mine bought an HTC One on ebay and he found out it was rooted/unlocked so he went to put it back to stock and may have bricked the device while doing so.
EDIT: so I am able to use fastboot, but not adb because I can't get into Windows. Flashing the stock Verizon RUU I found still doesn't get me anywhere though.
Is there any hope for this device? Thanks in advance!

You have to select bootloader to get to the recovery option. What kind of computer are you using and whats it running?

Yea I saw that after messing around with it some more. It is Windows 7 x64.
I tried the one at the bottom of the page as I can't find one anywhere else. I also used the commands at the bottom to try and flash it.

When you go to device manager on your pc with the phone pluged in and in fastboot mode, does it show android phone or unknown device? Try using these drivers http://vzw1files.dyndns.org/ADB/ADB_Drivers.zip
You need a signed ruu which you can get here http://vzw1files.dyndns.org/RUUs/2....2_NV_VZW_3.71_002_release_341019_signed_2.zip
fastboot oem rebootRUU
fastboot flash zip file.zip
May fail with flush error do above command again.
fastboot reboot

OK cool I will try that once it downloads. It shows "My HTC" in the device manager. Also with the fastboot devices command it does give me the device ID.
EDIT: That worked! Thanks a lot for the RUU file, as I could not find that anywhere.

Hello. A friend of mine has the same problem. She tried to flash this RUU: "RUU Zip M7_WL_JB_50_VZW_1.10.605.10_decrypted" but the phone doesn't boot. Here is more info about the problem: http://forum.xda-developers.com/showthread.php?t=2688936
Can she flash the RUU posted here?
This is what the hboot says:
Unlocked
m7_wlv pvt ship s-off rh
cid-11111111
hboot 1.54.0000
radio 1.12.42.0906
opendsp v31.120.274.0617
os 1.10.605.10
Thank you very much.

She can, but since she is s-off, its better to flash the decrypted one. http://vzw1files.dyndns.org/RUUs/2.10.605.1/PN07IMG_M7_WL_JB_50_VZW_2.10.605.1_DECRYPT.zip

First, thank you very much. She changed the CID to VZW__001. That's not a problem, right?
Does the CID and MID have to be compatible with the RUU? She has this MID: PN0731000.
Downloading this RUU, will report back.
Again, thank you.

Yes the cid and mid need to match the ruu. What you have now are the correct ones. However 11111111 is super cid, which would have also worked.

Hello again. Before we try to flash the RUU, I would like to ask you the steps to do it. This is what we gonna do:
1. Download RUU
2. Rename to "ruu.zip" (Optional)
3. Enter fastboot mode
4. enter "fastboot oem rebootRUU" - You should not see a silver HTC logo on your device.
5. enter "fastboot flash zip ruu.zip" - The first time you execute this command, it only prepares the flash
6. As soon as the flash is done preparing, enter the same exact command again "fastboot flash zip ruu.zip"
7. Now you'll see a little green progress bar on your phone. This does not need to reach 100%. As soon as your command window is finished, you can just "fastboot reboot".
8. You should be set back to fully stock HTC One.
And that's it? Nothing else is needed, right?
EDIT: we flashed the RUU. Now the phone boots always in fastboot. No matter what option we choose, the phone does nothing and goes back to fastboot. On the bottom of hboot there is a new line in red: "Active cmdline overflow! (1073 Bytes)"

Ok try changing the cid back to 11111111 super cid, then run the ruu again and see what happens. Before doing both, use the cmd
fastboot erase cache

Hello. We just did it, and still the same problem. We were reading that some people solved this by doing a downgrade to hboot 1.44. But I don't want to make this problem worse.

You can try it, its worth a shot. Just flash an older ruu. http://vzw1files.dyndns.org/RUUs/. Dont remember which one goes with 1.44

You can't be more kind. We made a downgrade, and now we can use CWM again. (We did the downgrade before reading your post, so we didn't use an older RUU) Now thinking hwat should be the next step: flashing a ROM (custom or stock, mounting a pendrive) or flashing an older RUU or anything else. Again, dude, you're awesome.

I'm stuck in a similar situation and any help would be appreciated so I don't screw this up. I can get into the bootloader but not into recovery (gets to the first TWRP screen then reboots). Safe mode works fine too.

Similar problem here.

Only fastboot. Can't access to recovey (CWM). Can't access to OS, so no adb.
Every time I try to RUU it gives the "Signature verify fail" message.
So, I tried encrypted ROMs (those at vzw1files. dyndns. org), and I could go a step forward; but the flashing hungs up after giving this messages:

(bootloader) zip header checking...
(bootloader) zip info parsing...

Thanks in advance, I hope I didn't screw it up.

The problem is nicouy that you are s-on, and on the newest kk firmware. An s-on phone will not allow you to "downgrade" firmware, and we do not yet have the latest ruu available, at least to my knowledge. So your kind of screwed right now untill we get our hands on a kk ruu.

[Q] RUU failed. Now stuck on htc logo. Dead?

Tried to install latest RUU file and failed. Now phone is stuck on htc logo with black screen only when plugged in pc. Also when unplugged, goes to bootload with no options and only shows RUU.
Phone is unlocked and s-off. Had Bootloader installed and now wont show
Need help ASAP
Thanks

are you s-off ? is your phone a GSM M8 ?

Did you try the other method, just renaming the RUU to 0p6bimg.zip (<a 0 (Zero) not a capital o (O), naturally...)
What error do you get when the flashing of the RUU fails?
Like mentioned by clsA said, adb devices won't work in fastboot mode, it should be "fastboot devices" to check if it's connected

try and unplug the phone from the pc and hold volume up + power for 10 seconds
when the phone reboots try the ruu again .. if the bootloader says RUU in red don't do the fastboot oem rebootRUU command just go straight to flashing
The RUU flashes very slow are you waiting long enough ?

you have the file renamed just copy it to your Ext - sdcard and let the bootloader flash it
don't forget to delete or rename it on the sdcard before you reboot again or it will flash it again

Yeah this pretty much tells me you didn't properly read the guide to converting your device to GPE. When I mentioned "the 0p6bimg.zip" method I kind of figured you'd know to place it on SD Card and reboot into bootloader so that the bootloader can pick up the .zip file and flash it from there. Flashing in from RUU sort of gave it away there
Method 1
No computer required. Everything else still required. s-off, super CID/gpe CID etc..
1. Rename the RUU zip file 0p6bimg.zip (if your hboot is looking for a different name then rename it to whatever it's looking for)
2. Place the zip on your external SD card
3. Power off your phone
4. Boot into Hboot (hold down vol down as you power on the device)
5. it will load the zip and ask you if you want to proceed
6. Say yes
7. Wait
8. Profit

Reverting to stock to sell - best method?

I bought an M8 last year, locked to vodafone UK (CID VODAP001). I have since unlocked through HTC-DEV, S-OFFed using sunshine, converted to GPE for a while, and am now using it on a developer CID (BS_US002) entirely stock in order to get the OTA lollipop update straight from HTC. I obviously have the tampered message and unlocked bootloader, I am looking to return it to stock as much as possible (apart from S-ON). I have been looking at this thread but am not sure if it will work. I was looking to keep stock lollisense. My question is do I need to change my CID/MID back to the original ones or can I leave them as is and remove the tampered message etc.

My guide will work but there are bits that aren't needed now we have the RUU. I'll post in the morning with proper steps as I'm my phone at the mo and links are a PITA on here!

Much appreciated! I'll check back tomorrow.

Right, lets try and get this sorted. As you're S-OFF it'll make things a LOT easier!
First, download the following and put them in your fastboot folder:
4.16.401.10 RUU ZIP - https://drive.google.com/file/d/0B17smFr95pleU2NqcVB3NWxoNnM/view (rename it ruu.zip - not ruu.zip.zip!)
htc_fastboot.exe - https://www.androidfilehost.com/?fid=95897840722646249 (you can leave the name as it is)
1. Personally, I'd get the tamper flag and the locking done first SO root the phone if you haven't already and then use the guides by @scotty1223 - Tamper Flag & Locking the bootloader. You can also, apparently, do the commands in TWRP as the recovery already has root access so if you'd prefer flash the latest TWRP found HERE (fastboot flash recovery recovery.img) and then connect the phone when in TWRP and do the commands as highlighted by the guides by Scotty. Also, if you changed the MID at all, change that back using Scotty's guide HERE
2. Once you've reset the tamper flag and locked the phone (but still S-OFF), change the CID to Super CID - fastboot oem writecid 11111111
3. Reboot the bootloader to confirm it's done - fastboot reboot-bootloader
4. Now we should be in a position to flash the EU RUU file SO reboot the phone into RUU mode - fastboot oem rebootRUU
5. Once in RUU mode, we now have to use the HTC fastboot to flash the ZIP - htc_fastboot flash zip ruu.zip
6. The ZIP will take a few passes to complete and it'll reboot the phone accordingly
7. Once complete, reboot to the bootloader again - fastboot reboot-bootloader
8. Chance the CID to the unbranded EU one - fastboot oem writecid HTC__001
9. Again, reboot the bootloader to make sure it's taken - fastboot reboot-bootloader
10. Once confirmed, boot into the stock recovery and do a factory reset (optional but, personally, I'd do it)
11. Reboot

Nope, the Google one doesn't work for some reason. HOWEVER, apparently there is an HTC version on the HTC Dev site, which might very well work...

Help a Newbie to rid GPE RUU

Hi folks
I have recently bought a HTC One M8 on ebay which was converted to play edition by the seller using GPE RUU. I know very little about this but would like to attempt to return to stock whilst ensuring no flagged messages are left on.
I have searched and only come across guides that are specific to specific circumstances. Does anyone have or know of a general and safe guide that would work in my case?
Any help greatly appreciated.
Thanks in Advance
Sid

Do you have any idea what version the phone was running before GPe? Can you see the model number at the bottom of the back of the phone?

model: OP6B100
No idea what it was running before.

OK, going by that ID we can assume it's an EU unbranded handset. Or we can at least we can treat it as such. So, assuming you want to go back to 100% stock Sense (but keep S-OFF) do the following:
First, download the following to your fastboot folder:
4.16.401.10 RUU ZIP - https://drive.google.com/file/d/0B17smFr95pleU2NqcVB3NWxoNnM/view (rename it ruu.zip - not ruu.zip.zip)
htc_fastboot.exe - https://www.androidfilehost.com/?fid=95897840722646249
1.54.401.5 FW ZIP - http://www.androidfilehost.com/?fid=23329332407589439 (rename it firmware.zip)
TWRP - http://techerrata.com/file/twrp2/m8/openrecovery-twrp-2.8.4.0-m8.img (rename it to recovery.img)
HTC Sync Manager (for the drivers) - http://www.htc.com/uk/support/software/htc-sync-manager.aspx (install it and then uninstall Sync Manager but leave the drivers)
1. First things first, change the CID to Super CID - fastboot oem writecid 11111111
2. Once done, reboot the bootloader to confirm it's showing the Super CID - fastboot reboot-bootloader
3. Once confirmed it's set, we now need to set the right MID in case this was changed by the seller. To do this, we can use TWRP. Flash TWRP (downloaded earlier) - fastboot flash recovery recovery.img
4. Once flashed, boot into TWRP and connect the phone to your PC
5. Once the drivers are installed, make sure the PC sees the phone by typing adb devices
6. So long as it's been shown as a connected device, type adb shell
7. We can now change the MID to the EU unbranded one by using the following command (copy/paste this as it has to be exact)
Code:
echo -ne '\x30\x00\x50\x00\x36\x00\x42\x00\x31\x00\x30\x00\x30\x00\x30\x00\x30' | dd of=/dev/block/mmcblk0p5 bs=1 seek=16384
8. Once done, we can now 'lock' the bootloader using the following command (whilst still in adb shell)
Code:
echo -ne '\x00\x00\x00\x00' | dd of=/dev/block/mmcblk0p2 bs=1 seek=33796
9. And we can also reset the tamper flag at the same time
Code:
echo -ne '\x00' | dd of=/dev/block/mmcblk0p6 bs=1 seek=5314564
10. Once all that is done, type exit to leave adb shell and then reboot the phone into the bootloader through the reboot menu in TWRP
11. Once back at the bootloader, you should find the phone is now 'LOCKED' and it shouldn't say 'TAMPERED' at the top either but should still have the black bootloader interface that the GPe has. We can now set it all back to Sense
12. Reboot the phone into RUU mode - fastboot oem rebootRUU
13. Once in RUU mode, flash the firmware ZIP - fastboot flash zip firmware.zip
14. The process will fail the first time and reboot. Run the same command again once it's rebooted - fastboot flash zip firmware.zip
15. Once finished, reboot the phone to the bootloader to confirm you now have the white 'Sense' bootloader - fastboot reboot-bootloader
16. Assuming it's correctly flashed, reboot back into RUU mode - fastboot oem rebootRUU
17. We can now flash the RUU using the htc_fastboot package - htc_fastboot flash zip ruu.zip
18. Once finished, reboot back to the bootloader one last time - fastboot reboot-bootloader
19. Once back in the bootloader, change the CID to HTC__001 - fastboot oem writecid HTC__001
20. Reboot the bootloader to confirm the change has been successful - fastboot reboot-bootloader
21. Once back at the boot loader, disconnect the phone and boot into recovery and do a factory reset
22. Once the reset finishes, reboot the phone
That should get it all working but any issues obviously let us know

Fastboot folder? I did say i was a newbie! thanks

OK, perhaps it might be worth reading up on fastboot/adb before doing anything as the above isn't for the faint-hearted!
EDIT: I've attached my 'fastboot' folder. Extract it to the root of your C: drive so it's easy to get to. All the commands in my guide are done through a command prompt in Windows starting in that folder, e.g. C:\platform-tools\fastboot oem rebootRUU
https://drive.google.com/file/d/0B8L4pkbzdlR3Z3dsNGZfSWhCeTA/view

ok, I have installed fastboot adb andi have a folder called adb in my c:. I am now downloading all the items listed above and renaming as appropriate and moving to the folder named adb. am I on the right track?

Getting there. You could've just downloaded/extracted the folder I linked to on your C: drive but as long as the contents is somewhere you can easily find you should be OK

i have the same problem but mine is in a loop.... my htc m8 is an 0P6B700, ive tried to convert it to a lollipop GOOGL001 but it didnt work... and i am stuck in bootloader.... i have already installed the twrp 2.8... and i have the working the fastboot in my pc... but i dont know what to do....

Please start your own thread rather than hijacking someone else's, and also post your output from fastboot getvar all so we can work out what's best to get you back up and running

I know your getting help here, but...Can I ask..
When you bought the One M8 on eBay, did the ad or photos say you were buying an M8 unlocked and Converted from Sense to GPE.
If Not, you do know youve been sold an incorrect product and you have a case against the seller for false advertising, so save yoursewlf the issues, exersize your rights and send it back.
Plus, you say you are new to flashing / unlocking, so if you brick this M8, you dont have any returns room.
Just wanted to say that and hope it helps. Good Luck

thank you..

Change your CID to BS_US001 and MID to 0PJA11000 then the ruu will work.
You're S-OFF so it's simple to change, just boot in download mode and use: "fastboot oem writecid BS_US001" and "fastboot oem writemid 0PJA11000"

You just need S-OFF that I saw you have, so boot in download and do the commands.
