1. Lock the Bootloader. To do this, run the command: fastboot oem lock
2. Drop the file Nutegsm gave you to the memory stick and rename it to 0P6BIMG.zip, the zip extension may be hidden.
3. Insert the card with the soft into the phone and turn on the Bootloader.
4. Follow the instructions on the phone screen.
5. If it fails, give more data, such as: MID, CID etc.

Something strange happened, I recharged my phone, I turned it on, I waited a while and the android started. I turned off and turned on, waited a bit and the android fired. It came a week later, a message was displayed that a system file was missing and would not turn on. It looks like there is android on the phone but there is something wrong with it because today it turned on but google play does not work. A message appears when switching on

Perform a hard reset or reload the firmware.

Should I do that
INSTALLATION:
Make a nandroid backup first
Download the ROM
Extract boot.img from the zip file

Fullwipe
Flash ROM
Fix Permissions - click on recovery
Reboot to bootloader
Go to fastboot mode
Flash the unpacked boot.img from Rom via fastboot
Fastboot erase cache
Wait a few minutes for the first run

I put the memory card with the ROM into the phone and something like this pops up When I go to TWRP and want to install it shows something like this

nutergsm · Answer

Look for another rom. Read this topic

mekoy · Answer

I cannot connect HTC to my laptop. I downloaded HTC Sync Manager and HTCDriver laptop does not see the phone. I tried another rom for the same. Everything would be fine if the Bootloader was RELOCKED or LOCKED and I would know what the CID / MID is.

nutergsm · Answer

Since the above methods do not help, go to the website where they will upload the new firmware.

mekoy · Answer

I was able to get the Bootloader to RELOCKED. Unfortunately, when I try to install the room, the CID incorrect error appears. I know this means a non-compliant CID. I can't change it to SuperCID because I don't have s-off.

nutergsm · Answer

Take it to the site. Let them do S-OFF and change the CID and you will be able to upload whatever you want.

mekoy · Answer

I returned the phone to the service.
