HTC One m7 (m7ul) black screen

Hello,
The other day i :
- Install PC driver for htc one m7
- I root my phone
- I unlock the boot loader
- I install TWRP (twrp-3.0.0-2-m7)
All of this without a problem !
Next i try to install Cyanogenmod 13, obviously a bad idea becuse my phone is on android 4.4.(3 or 4) and i choose the m7 version not the m7ul.
Now my PC don't recognize my phone anymore and when i press the power button the phone starts and show a bright black screen.
I've access to bootloader but the recovery don't whant to starts.
I try factory reset with no success.

Afaik, the "M7_UL" variant was merged to "M7" so you've flashed the right one.
Now my PC don't recognize my phone anymore

Isn't your phone detected when selecting "FASTBOOT" from the bootloader? You should then see "FASTBOOT USB" in red. From there you should update your firmware to at least 7.19.401.2 and reflash your recovery/rom if needed.

Factory reset is often misinterpreted. A factory reset will ne revert anything back to its factory state after you've modded your phone. The only thing it's doing is wiping the /data partition where your personal data and app data are stored. The rom didn't booted so there is nothing to wipe in /data that could fix your phone.

Code:
fastboot oem rebootRUU
fastboot flash zip M7_UL_Firmware_7.19.401.2.zip
fastboot flash zip M7_UL_Firmware_7.19.401.2.zip
fastboot reboot-bootloader

Code:
fastboot flash recovery twrp-3.0.M5-0-m7univ.img
fastboot erase cache
fastboot reboot-bootloader
Then try to boot in recovery and reflash your rom (if needed).
If its still not working you could flash the latest ruu and try again.

No just after i flash the rom my computer (windows 7 x64) stop recognize the phone.
I try on a win10 today my htc show a fastboot in red but no fastboot usb.
I'm blocked here. :s
Thanks

Cant oem unlock my nexus 6

So before I start I just wanted to say that I have been rooting and installing roms back at the time when I had my galaxy s3, I knew this stuff before upgrading to my nexus 6.
So the problem as you can see on the title that I cant unlock the oem option, means I cant unlock my bootloader, but there is a twist.
When I bought my nexus, I remember it was 5.0, and there was an update to 5.1, the update was OTA, and I remember the update had problems, it couldn't finish and the phone stayed on 5.0 and you could not
update to 5.1 unless you flash 5.0 again. So I unlocked my bootloader back at the time, and installed 5.0 all over again, and everthing was fine until now(now I am on 7.0)
Now I want to root my phone and install things and I cant do that, because of the oem options, but when i go into fastboot it says device is unlocked, and when I turn my phone on under the google sign there is small open lock sign that I know tells the bootloader is unlocked.
So there is my problem, I cant root it and so on, very sorry of the long post but I think it was necessary so I could explaine my problem.

Not quite sure what your problem is. Your bootloader is already unlocked, you just flash twrp via faatboot
Code:
faatboot flash recovery nameoffile.img
then flash SuperSU. If it asks for a password, or you can't find any files on your device in twrp, that means you're encrypted, and will have to completely wipe data on device. You do that by hitting cancel (if it's asking for a password) then go to wipe. Then select format. You'll have to type yes. Now you'll be unencrypted.
As a side note, you may be able to get away with just flashing twrp, and then sideloading the SuperSU zip

Thank you very much, apparently it worked even if the oem option is not available, hope I wont get into more troubles.

Question I locked the bootloader by misstake

Hello, what I did was the following:
1. signed on a new phone with account A, waited a week and unlocked the bootloader
2. signed on the same phone with account B
3. flashed fastboot rom on the device with mi flash tool, but forgot to uncheck the " lock the bootloader"
4. the phone is not starting - i can only get the recovery and the fastboot mode.
5. mi flash tool wont let me flash to locked device . Mi flash tool2 makes me go into Mi assistant mode, starts the instalation process but failes after a few mins ( on the pc i reach ~ 700% but on the phone the bar is on 4.99 or 52.78 % )
6. Xiaomi ADB/Fastboot Tools doesnt want to flash as the device is locked and if i try the OEM UNLOCK button i get "FAILED (status read failed (Too many links))"
7. If I try to unlock the bootloader again and I log account B i get message that i need to log on the phone and wait for a week
If i log accont A i get this :
{
"lightbox_close": "Close",
"lightbox_next": "Next",

Any Idea how to fix it
Thanks in advance, and sorry if this is the wrong place for this question

As far as I know, the only way is to ask after-sale for help.

They might have more underlying tools to unlock and flash your phone.

fastboot flashing unlock
for most of aosp rom this is the command. but i'm not sure that works on miui. i found a java tool that maybe can help you. https://miui.blog/any-devices/xiaomi-adb-fastboot-tools-one-utility/ i have used to debrand my phone without unlock it

I had to send it to a friend of mine who was able to install chaina rom, using EDL mode, but now, for some reason the IMEI's are gone. I can not add mi account, and for that reason I can't unlock the bootloader, right now I am battaling with the IMEI restoration ( i have the original imei's on the phone case) I am trying to use modem_meta_tool, but with no suxcess . I can't get my phone connected
Long story short, EDL mode was needed to get out of my original situation

seem you have lost imei cause you have installed china rom. or a rom incompatible with your region. try install global rom via edl. but if you lost imei, restore it is not simply... you can try to enter into engineering mode. i'm not sure but there's a function to change imei. but not working for all mtk processors

Question Soft-Bricked - How to Recover?

Hy Guys,
i rly need your helps.
I Installed the Xioami.eu A12 Beta Rom (and used the windows_fastboot_first_install_with_data_format.bat).
The Script runs thorugh the installation process and after that my phone did a reboot.
And now it appears the screen with
"This device is locked,
This device is associated with an existing Mi Account. For security reasons, you need to enter password to verify the device"
but it seems that the touch screen is not working, so i can't select the network or move into the enter password field.
After seome seconds the phone reboots and ends up in the same screen.
1) Bootloader is unlocked
2) Enter Recovery is still possible (and via MiAssistant recognized by windows)
3) Enter Fastboot is possible but not reconized by windows anymore
but i dont know how i can now get my phone back to work ;-(
I hope someone can help my and let me know what i can do.
For the Final Solution i will pay 25€ as a little gift ;-)
//Edit: Ok i can now Enter Fastboot again (via MiAssistent an then "abd reboot fastboot") and its recognized in windows but when i try to reflash the A12 i got a lot of errors:

}
After this reflash, phone still stuck on the "This device is locked" and Touch still not working ;-(
//Edit: If i try to flash A11 via MiFlash i get the following error:

You might have fully bricked it, the initial problem you was just about entering you Xiaomi account password cause your device is protected by find me the xiaomi find device APp

try to recover with the venus engineering rom which was posted

1. Enter in fastboot mode.
2, reflash xiaomi eu 12.6 21.22.10 (and use the windows_fastboot_first_install_with_data_format.bat).
3, phone autostartup
4,first screen go to wireless, set
5.Back, enter yours passord an your xiaomi mi user.

You can try two others things because apparently you have access to fastboot mode
1/ Flash lastest Stable Xiaomi .eu A11 from TWRP (Boot TWRP, format data, reboot TWRP, flash Xiaomi.eu)
2/ Flash AOSP ROM from LOS Recovery (but you must have a stable base A11 MIUI before)
and you don't have locked device prompt on the AOSP rom

forum.xda-developers.com
Just as described I've downloaded Nokia drivers. My phone already had unlocked bootloader via official HMD method so i went over to the next step and T-Virus.
I entered fastboot sucesfully by enabling USB debugging. Downloaded T-Virus from the guide link and executed Windows command. Followed all steps in command window.
During the process I've noticed repeating error "Invalid sparse file format at header magic" if it's important.
Anway it finished and said that my phone will enter ROM now but after restarting it's back at bootloader.
I tried entering recovery via key combinations but they won't work.
I can detect my phone in fastboot and even when i type in
fastboot reboot recovery
It will still reboot into download mode.
Any help appreciated how to get my phone to work again.

Okay, crisis averted, I reverted T-Virus and now i can boot to android again.
But I still want to know why T-Virus failed and cause bootloop on my device?

I've noticed that despite having unlocked bootloader my critical is locked. Could t

Yup that was it.
I had to repeat fastboot flash unlock unlock.key and then fastboot flashing unlock_critical to get critical unlocked and now T-Virus installed without any issues.

Hey got the same problem, how did you revert and unlock critical?
