Need some help if someone can do that
- I have oem unlocked my b/l with unlock code, install twrp, try some polished rom but i don't like it and try to go back to oem locked state to flash an RUU file through ADB...
When i go to download/fastboot mode and type a "fastboot oem lock" command i have a message
"C:\adb>fastboot oem lock
...
(bootloader) [KillSwitch] : /dev/block/bootdevice/by-name/frp
(bootloader) [KillSwitch] Last Byte is 0X01, enable unlock
OKAY [ 0.028s]
finished. total time: 0.029s"
to my PC and on my phone i have a question "Yes to OEM lock and hard reset or No to live..."
I point to Yes and when confirm that my phone rebooted to a loop rebooting and blinking display with HTC logo and red words text...
Whatever i try to do it's always blinking/rebooting
Is there any way to normallise my phone and turn to any normal state?!
TNX
I moved out from previous state!!!
What a luck!
Dont know how but pressed VolUp+VolDown+Power and gone to bootloader state. After that have to unlock b/l again and after that when gone to Recovery, my TWRP is still there what a sweetness....
When enter to TWRP just some quick tex "Decrypting phone" and immediately rebooting to a normal state with all working phone states!
Is there any way to lock b/l again, turn to OEM state and to do a normal/regular HTC updating???
My last HTC update was 1.64.401.10 and European version...
Any advice?
TNX
Flash stock recovery: https://forum.xda-developers.com/u-ultra/development/unlocked-model-stock-recovery-t3585622 and you should be able to lock your bootloader successfully.
Never update with a third-party recovery. After you are done updating, install custom recovery again.
Ok.
I didn't know that
Tnx

Hi,
This is my situation.
My Nexus 7 Wifi suddenly won't turn on.
It get's stucked at the Google B/W page.
I can get into fastboot mode by pressing the volume down and turn on bottoms but I can't unlock my bootloader.
If I choose "Recovery Mode" I get a "Booting Failed" message and nothing happens.
Any advice?
Thanks in advance for your kind attention to my problem.

Don't make us guess; please post (copy & paste) the complete output that results from running the two commands:
fastboot devices
fastboot oem unlock
Sorry... here you have the messages:

Hmmm
That's pretty definitive. Send it back for repair/replacement.
I suppose you could try installing the factory ROM, but I'm not optimistic that will succeed.
Out of curiousity (even though I think it had nothing to do with the failure), had you enabled the "encrypt device" functionality at any previous time?
Besides I know the normal procedures to unlock, route, etc ... I never thought I wanted to do that with this device.
It was used by my wife and daughter so I never activated anything. I left it as it came from factory.
So, nothing to do but return it for an exchange?
moto g4 on-then reboot and recovery screen-tried flashing without bootloader unlock-flashing ok-still same problem

Not getting this lines, did you try to flash stock ROM..??
I have tried downgraded my phone from nougat, but has ended in at bootloop only showing the red Huawei Logo.
Now i can´t enter recovery, can´t update using 3 button method only thing i can access is fastboot.
My problem is my bootloader is locked and therefore i can´t flash an recovery. And now i cannot figure out how to obtain my product key, so i can unlock the bootloader.
Any1 who can help me with this would be much appreciate.
What did you do exactly to end with endless bootloop?
I used the rollback file from this Thread:
https://forum.xda-developers.com/hu...torial-rollback-n-to-mm-c432-devices-t3563955
Update went fine but afterwards it ended in a bootloop. The only thing i can access is fastboot.
The weird thing is that in fastboot it says my bootlader is unlocked with red, but i cant install an recovery. Its says acess denied and ask if i'm sure my bootloader is unlocked.
And thats why im back to trying to unlock the bootloader but i cant get the product id for my phone when i can't turn in on.. seems hopeless
I suppose that you did 3 button update metod. You have to factory reset phone. Press volume up and power button together and keep pressed until you see erecovery option for factory reset phone. Do it.

I cant. Have tried all the button combinations to enter both recovery and update mode but nothing works, only vibrates and showing huawei logo. Only thing i can access is fastboot through computer
With huawei extractor extract (from B160 or what ever firmware is your phone) system, boot, and recovery img and flash with adb. Than you have to do reset.

Thanks for the suggestion.
When i try flashing it with adb it starts writing but then says "Failed (remote: Command not allowed)
Should have installed the proper drivers but still not working.
Same thing if try flashing with the L31 toolkit. Here it says "Something went wrong! - Maybe your boot-loader is locked?"
The only thing i can think of, is trying to unlock my bootloader again and see if its work. Even though it says unlocked in fastboot mode. But for that i still need the product id for my phone which i can´t get???

unlock bootloader code is not eligible for that IMEI (14 days limit...)
anyway, if you can not enter in fastboot mode, you can do anything...
go to service center or try DC Phoenix via a small fee (10-20 euros)...
i can enter fastboot, what next?

Hello, i have a serious problem with my U Ultra.... Last night I unlocked the bootloader, I installed TWRP(lastest version from official site), before all this I made backup (with TWRP) of every partition and then I make back-up of system, data, boot I think, I have everything on my laptop.
But I wanted to back on stock (Don't ask me why...) and i restored a back-up, a full back-up of every partitions. Everything great, but google play didn't had Device Certification: Uncertified like in this pic and I tried to do this method and it didn't worked and I don't know why I thought that if I will relock the bootloader, everything will be okay :| and now I don't have TWRP anymore and of course neither stock recovery, but the stock rom boots but the password I have made it, is not working.
Tried to unlock bootloader but this error shows up
Code:
diesel-X550CL Downloads # fastboot flash unlocktoken Unlock_code.bin

Now how can I solve this problem?
How did you did the bootloader relocking?
For what purpose you need the Google Play certification?

Through fastboot with this command:
Code:
fastboot oem lock
I don't need it for a special purpose but some apps don't work and I saw that was the solution, anyways I don't need that no more, I just want the phone to work....
Just go to fastboot mode perform oem unlock and reinstall the twrp

You don't need to use the HTC file. Your phone is permanently hardware unlocked since the first flash.
All you now need to do is simple
Code:
fastboot oem unlock

Then what I can only advise is getting RUU of your system's current or newer version and force to reflash everything including bootloader.

I have the same issue after relocking my phone. Before I decided to lock my phone to downgrade to nougat, I did flash twrp and a rooted stocked oreo rom. After locking my phone using fastboot my phone stuck into download mode bootloop, I was able to get into download mode properly but I couldn't afford to download ruu from easy-firmware to flash in ruu mode

I couldn't solve the problem myself, so I went to a gsm service and they couldn't solve it, 1 month of trying and one day my dad told me to go to the warranty service and I didn't, he went there and I don't know how they accepted the phone with the another reason and in a hour they solved the problem. I'm still using the phone and I can't wait to get rid of it.
So... I don't know how to help you, you should go to a gsm service, regards!

Hello,
Already 1 week i tryto unlock my lg g6 again.
I would like install stock rom and for that i have lock again the bootloader.
This is a stupid action, now i can't do anything.
I cant reverte with unlock.bin
fastboot flash unlock unlock.bin
Sending 'unlock' (1 KB) OKAY [ 0.040s]
Writing 'unlock' FAILED (remote: 'oem unlock is not allowed')
Anyone can help me please ?
Thank you.
Are you able to boot into the phone? It's refusing because the oem unlock option is not ticked in developer options.
If you can't boot your phone, download the stock ROM for your model and flash it with the LG Flash tool
https://lgflash.com/download/
Boot into download mode by holding the vol up key with the phone plugged into your computer to start the download mode.
Hope this helps.
I can see on lock try LG flash to with out succes.
I can boot in download mode.
But the device is lock in developpement option.
