Stuck in bootloader

Hi everyone,
I'm asking help for someone in an other forum.
Impossible for him to flash anny RUU ou PC10IMG.zip, even one with the same number 2.42.405.4
Problem with drivers after trying many times with sdk and htcsync!
Just possible to try to send command via fastboot, but not working.
No access to recovery or command via adb.
Staock Rom, S-On.
What could be done? Goldcard and root?
Is it the same that this one : http://forum.xda-developers.com/showthread.php?t=1759575?

HTC M8 TMO Signature error 12 Can't get back to stock

I am fixing this phone for a friend. He gave me the phone with TWRP installed, and Bootloader unlocked with S-OFF ON.
I tried to relock bootloader to flash stock RUU_M8_TMOUS_1.57.531.7 and it fails with error 12 bootloader signature verification error.
Then relocked the bootloader and got into twrp. Nothing will mount. The phone won't clear cache, Data, system , Dalvik or anything else.
I tried to restore a nandroid backup and it fails. Literally everything fails, and all fastboot flashes end with error 12.
What is the bootloader signature verification error 12? Please help me, I'm kinda stumped.
Here's the get VAR information:

Unlock the bootloader, adb push the correct nandroid backup to the phone. Fastboot flash the boot.img and perform a full wipe and restore the backup.

Cause you're S-ON you can't flash an older HBOOT onto the phone so the RUU will fail

As my phone was rooted and had twrp recovery installed i need to flash a stock recovery image, i found a 4.20.206.1 image and did the following....
renamed 4.20.206.1 to 'recover.img'.
Booted phone into fastboot then used the command...
'fastboot flash recovery recovery.img'
and got the following
target reported max download size of 1826414592 bytes
sending 'recovery' (17020 KB)...
OKAY [ 1.559s]
writing 'recovery'...
OKAY [ 0.737s]
finished. total time: 2.302s
then typed 'fastboot reboot'
device rebooted and then i proceeded to install and update the latest system update (4.20.206.2) after this the phone restarted and got stuck on the white HTC logo screen, left it for 10 minutes and nothing happened had to press and hold Power+Volume UP button to reboot the phone and now it get stuck on a black screen.
Any ideas on whats happened, i can still get into fastboot and have reinstalled twrp, what steps do i need to do next?

Your main problem is you have a rooted stock ROM and its binary was modified by root.
You need a non-rooted stock ROM like a RUU or a clean non-rooted nandroid backup.
Re-unrooted a rooted stock ROM won't work due to changed/modified binary.

Fastboot help please :(

Just solved one problem with the drivers, now the fastboot prompt tell me, the signature checking failed..

I have locked my bootloader and tried to flash a "signed" fw.. tried it from 2 sources. Also tried to flash a recovery. Nothing worked..
Edit: As an act of last hope I "reopened" my bootloader. That way I was able to get into twrp and flash a ROM after a wipe. Now I can use at least my Smartphone again. But of course it would be great to know what I did wrong..

The Bootloader said "relocked". It still did not work.

Can we solve? HTC ONE M8 is resting to same faulty state and no options are working

I have a HTC one m8 (AT&T). The phone is in boot loop mode. I tried a lot of options, but nothing worked and device is resetting to same faulty state as before.
I am looking for alternate solutions and suggestions, which I did not try but exist. Request you to please respond.
Options tried :
Unlock boot loader - Not working - Same previous state after unlock boot loaded option. Still locked
Factory reset/Hard reset - Not working
Recovery - Not working
Update through sync manager - Not working , HTC sync manager is not recognizing the phone, as it restarts after few minutes.
RRU update with EXE : Not working - RUU_M8_UL_M60_SENSE70_ATT_MR_Cingular_US_6.20.502 .5_combined.exe as during the setup phone was not recognizable and restart in few minutes
Tried to update RRU.zip - Not working and getting below message
"RRU.zip is extracted with from HTC support site for HTC one M8 ATT official update file "RUU_M8_UL_M60_SENSE70_ATT_MR_Cingular_US_6.20.502 .5_combined.exe""
