[Q] fastboot oem lock not working, trying to relock bootloader to flash RUU

Hello, I am trying to re-lock my bootloader using the "fastboot oem lock" command in adb but it is giving me this error:
...
(bootloader) [PGFS] partition_update_pgfs: pg1fs_security
(bootloader) TZ_HTC_SVC_ENC ret = 0

Has anyone ran into this situation before? Any help would be greatly appreciated. My phone decided today that it wasn't going to work properly. When I boot the phone the OS itself is sluggish and inoperable. I want to just flash an RUU for convenience but getting my bootloader relocked is proving to be difficult. Thanks in advance!

Stuck on boot screen after unrooting and installing OTA update

Hi guys
So today I decided to unroot my phone and restore the stock ROM. I started by restoring backup that I made using TWRP before installing the custom ROM. After installing the stock ROM I powered on the phone and found the SuperSU was installed so I went to the settings and unrooted my phone. After that, I downloaded stock recovery file 4.16.401.10 from this thread forum.xda-developers.com/showpost.php?p=60211779&postcount=4> and flashed it on my phone.
Everything was working fine until I installed a OTA and after installing the update, it got stuck on HTC boot screen. I tried pressing volume up+ power buttons but the screen goes black after the first boot screen. I tried factory reset and clearing cash partition but to no avail. When I factory reset my phone it passes the first boot screen but it get stuck in the second boot screen where it shows HTC one m8.
I used fastboot before unrooting to get my cid and other information.

Please help I feel like my phone is bricked for good

You can't use a unrooted backup to do OTA .. won't work. OTA needs a pure non-rooted stock ROM to proceed.
Why don't you start again ... reinstall TWRP then restore the non-rooted backup (you can get the backup from the same thread where you got your stock recovery)
Or .. relock bootloader then install RUU zip - http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6

Thank you for your reply.
I was finally able to get my m8 working after couple of tries of flashing stock ROM on my device. First, I extracted the zip file from the RUU and renamed rom.zip to 0P6BIMG.zip. After I've moved the file to my SD card and booted up my device I got the following error
PHP:
Device Halted due to Large Image update fail! Press <Power> to reboot
and my device kept rebooting so I took out the SD card.
Then I followed the instruction from this thread http://forum.xda-developers.com/htc-one-m8/general/guide-restore-european-htc-one-m8-to-t3072235 and I finally got my device working :victory:.
All the steps went okay except an error that I got when trying to lock the bootloader

but I just skipped it and started the RUU installation wizard and every thing went fine from there.
I still haven't tried to upgrade to Marshmallow and I doubt that I ever will, after the nightmare I experienced yesterday:laugh:. Beside, I don't see any significant upgrades compared to Lollipop.
I guess what caused this problem was the stock ROM that I restored using twrp. Maybe it was not installed properly. I should've installed fresh and clean stock ROM from the beginning.

Yes, I'm wondering the same.
Was the phone previously s-off, then made s-on again?
Additionally, you shouldn't need to change the phone back to the "stock" CID in order to RUU. The T-mob RUU should work fine with SuperCID.

M8 s-on, relocked bootloader custom recovery...cannot unlock bootloader again

hi mates,
here is my problem, m8 whit kikat, s-on.
I tried to update to version 5 per ota but by recovery custom I did not allow it, by mistake I gave a relock to the bootloader with the twrp now I can not unlock the bootloader nor can I put the original recovery because I always get the error failed signature , What I can do, i need to reflash the stock recovery.

request another unlock code from http://www.htcdev.com/bootloader/
and flash it then you can flash the stock recovery and do ota
or simply search for an RUU for your device variant ( if it's available ) and flash it while relocked

have you tried to back to stock using twrp backups ?
from this thread https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
it's the easiest way to back to stock and see if your problem is solved
also you can update through OTA easily ( just accept it ) also it doesn't matter if the bootloader is locked or unlocked in this method

did you used the suggested twrp version in the thread ( every backup have a suggested twrp version ) ?
if yes then try to format data in twrp then reboot to twrp and wipe all partitions then restore system and boot then reboot to system
if not solved i'm afraid it's a hardware failure and i can't help you further sorry

Try to flash this ruu with unlocked bootloader, I'm not sure It'll work but I think you have the developer edition which comes with an unlocked bootloader.

This statement doesn't tell us anything. It's worth listing the things you tried to flash, and the specific results for each. Otherwise, we waste your time and ours, as we guess or assume what you tried and didn't try.
Did you try to flash custom recovery TWRP? If so, which version number? Did you get an error message, or what was the failure mode or other results?

The RUU which corresponds with your current firmware number (main version in getvar: 6.12.401.4) is here:
https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
You can try to flash using htc_fastboot per the instructions, or SD card method.
If you can't get the RUU to work, relock the bootloader, or flash TWRP, I agree that it's probably emmc failure.

Help me please.
Help me please. Is this also a brick?

Please don't post same question to multiple threads. It is against forum rules to do so, as it clutters up the forum, and makes it very confusing for those trying to help you.
I've tried to help you in one of the 3 threads you posted in. So go look for it (now you see one of the reasons why cross posting is not a good idea?).
