XT1072 bootloop after replacing screen

Hi,
my friend has replaced the screen of his XT1072. Now the phone is stuck in a bootloop. He has never experimented with custom ROMs etc., so the developer options are disabled (no ADB, no unlock allowed). I can access the bootloader (locked, status 0) and connect via fastboot. Here is what I have tried so far:
select the "Recovery" option of the bootloader: immediately reboots into bootloop
fastboot oem unlock: not allowed (developer option not set)
flash CWM: Preflash validation failed
flash stock rom (as described here): Preflash validation failed
Are there typical hardware issues (forgotten connectors etc.) when replacing the screen of this phone? I don't know if it is a software problem, but what I find quite confusing is that the "Recovery" option of the bootloader does not do anything - not even before I tried the flashing stuff.
Any other ideas how I can get this thing running?
EDIT: I finally managed to flash the stock image. First I tried with fastboot on linux, then with mfastboot on windows. I also tried different images - probably the "Preflash validation failed" error was because of a wrong image. Still bootlooping and recovery option functionless.

[Help] message in fastboot "Boot up failed"

I try to put in on my Moto G 2014 recovery TWRP through an application called flashify, and agrochemical it no turn on nor load, have tried to make the rom procedure stock \ root \ hard reset (bootloader n no way do as n have access to the phone via USB, it n is found to provide the code where I would use it to make the bootloader)
None of the forward, from getting desperate to try to get my phone without spending a bundle
warnings in Fastboot:
hab check failed for boot
Failed to verify hab boot image
failed to validate boot image
Fastboot Reason: Fall-through from the normal boot mode

you mean the device only start on bootlader?

XT1563 bricked?? Forgot to unlock OEM in dev options

long story short, my relative came to me for help after he decided to install a new ROM and made a simple error of forgetting about the OEM unlock option in the settings menu beforehand. an error occurred along the way and he tried to go back to stock. now when the phone boots it goes into the bootloader (which is locked) and gives a start up failed message saying to use Software Repair Assistant.
trying to go into recovery gives a
Code:
AP Fastboot Flash Mode [Secure]
Fastboot Reason: UTAG *bootmode* configured as fastboot
failed to validate system image
ERROR : Failed to pass validation. backup to fastboot
Boot up failed
i tried flashing TWRP but its giving errors too. are there any known workarounds to unlocking the bootloader or forcing a recovery/twrp to work?
thanks, all

Unlocking the bootloader, etc.

I'm stuck.
My phone boots to the welcome screen all the way to the wifi selection but stops after that saying the setup wizard cannot launch. So I cannot go into phone settings to "enable OEM unlocking" to follow the official HTC procedure for the bootloader unlock (which was once unlocked but is now relocked).
I looks like I have no recovery, because I cannot boot into recovery, it just fails.
If I go to (what I thought was) Download/Fastboot mode and try to Fastboot flash twrp for example, it says: FAILED (remote: cannot flash this partition in s-on state) ----> but I then read that this was because I was NOT actually in Download Mode.
So I think I managed to get to Download mode and tried the Fastboot command to flash TWRP again and now it says: FAILED (remote: 9: SD_SECURITY_FAIL recovery and bootloader isn't BL_UNLOCK).
I suppose it means that my Bootloader isnt unlocked...but as mention initially, I cannot access the OS and enable the OEM unlocking toggle.
Since Fastboot isnt working, I dont know if an RUU would work.... And look like I will never know because everytime I launche the EXE file, it extracts, asks me to to accept the conditions, then nothing happens...
Please help!!

Click to expand...
Click to collapse
I am replying to myself. After trying several things on the phone, I went back to the OS's setup wizard. The second step (2 steps before the crash), has some text and one has a clickable link saying "learn more". It actually opens some phone settings, and from there, you can access all of the phone settings. So I was able to activate Dev mode, OEM unlock and debugging without going through the Wizard!!
Followed the BL unlock procedures on HTC website and as soon as it was unlocked, phone rebooted and TWRP reappeared! I'm saved!!
Thought I would share my discovery in case this ever happens to you too.
I also discovered another possible course of action. When accessing the same "link" to get to settings, go to the network settings and put the phone on Airplane mode. Go back to the setup wizard and skip the connection to wifi. I think it will skip the part of the Setup that made the OS crash.

Challenge for experts!

OK so I have this PRA-LX1, long story short after a dload tonight to go back to stock ROM I ended up with softbricked phone, I can only enter Fastboot/Rescue mode.
Anything else ends up either in error 8 (ROM) or error 11 (Recovery) error.
- I have access to fastboot via adb/fastboot in a PC terminal
- I have FRP Lock, Phone Locked
- Nearly any fastboot command I send ends up in FAILED (remote: command not allowed!)
- I have my bootloader unlock code, but can't unlock because no botting ROM to check OEM unlock in developer options
- Can't flash any recovery (fastboot "not allowed" error)
- Can't seem to launch a new Dload with Vol+&Vol-&Power. Gives black screen "error mode: please update system again - Error Func NO 11 (recovery image)"
I'll try to let the blank screen drain the battery to get a new try to the Dload method... tomorrow
