There is any way back to the older(older than 16.1220.1909.194) or the first fimware? I think maybe it's the fimware 16.1220.1909.194 newer than the unlock apps...I tried the ADB but cant wrrote the older fimware...
Sry for the image...looks like it can't show out by google cloud drive.
Plz help me guys.
Thx a lot.

same problem here. i tried the 1st firmware that came with it 2019 april .still same problem. this happened after i gave it service regarding a problem which is taking too much time to open gallery. they have reflashe the phone and gave to me with AndroidQ. i tried to unlock with the asus tool. it says network issue. then i downgraded to 16.1210.1904.75
and tried with no success. any help

Did you finally solved this problem?

I saw somewhere people saying to remove device pin before you try unlocking bootloader. I guess you can try that.

Anyone found a solution for the bootloader unlock?

Sorry for mutliple editing, coz pic not appearing correctly, imma noob ;/

Noob question: For Bootloader to be unlocked through official mi unlock tool, do u need 2 different internet connection?
Because, i have only one sim and use it to get internet, and have laptop connected to it, so when i put my redmi Y2 to fastboot, theres no internet connection to laptop during unlocking process.
I took the sim out of my fastbooted y2, same unknown error(-1) occured at 99%,
Then i put that sim into my older phone (not y2), and had laptop connected to it, it stopped at 99% again, but showed different error "Your MI ID not associated with a phone number".

This is what it shows:
So both errors happening at 99%, badly need some guidance from those who have unlocked bootloaders for their S2 or Y2 models using official MI Unlock Tool. Thank you

U need internet connection the entire time of unlocking

Boot Loader Logs: Start Up Failed

The phone fell and now when I turn it on I get a black screen with the header titled 'Boot Loader Logs' with the following message.
Your device didn't start up successfully. Use the Software Assist on Computer to repair your device. Connect your device to the computer to get the Software Assist.
Funny thing is when I do plug it into the computer -- nothing happens.
The phone it self recognizes the usb is plugged in and nothing more.
No boot-able A/B slot -- don't know what that means. Basically, is there anyway i could get this up and going without removing everything on the device ?
Mnd you im a noob to all of this so please take it easy.
I'm open to everything.

Good morning, I just had that problem since yesterday, I think a general formatting was done, even to the cell phone imei, I don't know if I can pick it up, I need help please, pdt: I don't know how to write so much in English, I speak Spanish

Click to expand...
Click to collapse
I investigated more, I realized that there is only slot a, b does not recognize, but at the moment of completely formatting with the data, it does not start

Blackview BV5800 MT6739 Oreo 8.1 FRP problem from ebay

Hi This is my first post here. I have done some searching and reading but I still have a problem.
I bought this phone off ebay with a broken screen as a project. I managed to replace the screen and got it working (first time doing this for me) but the phone has a pin and google lock that I didn't consider.
The seller isn't replying to my question of what is the pin.
I checked the IMEI numbers on IMEI24.com and it's not showing as stolen. I have attempted common pins with no luck.
I have done a factory reset to wipe the data. I have tried to flash the phone from the SD card but it's not working (see photo)

E: footer is wrong
E: Signature verification failed
E: error: 21
I've tried 2 different firmwares but same error each time.
The phone shows up in windows as attached to the PC but won't show any files and doesn't show up for 4uKey for Android. I've attempted to use adb but it won't connect to the phone either using CMD in admin mode.
I'm not a coder and I'm not that good with command prompt software.
Have I got any chance with this or do I just give it up as a bad job?
It seems a shame to junk a now working phone. But I know now not to buy a broken screened phone again!

27 views and no replies.
I'm going to give it up as a bad job and break it for parts. The battery is good at least and there's a chance that I can salvage the screen as well as being good practice for repairs.
If the board is locked is it any good to anyone?

Question Unable to Unlock Bootloader

Hello, I am new to XDA but not new to rooting Xperia devices. However, I just purchased an Xperia 5 III and despite following the guide published here and following the Sony site with instructions I am getting the following error when I type the command: "fastboot oem unlock 0x<sony unlock code>"
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I've use the same process on other Xperia devices without issues. Everything including the prerequisites (SDK, drivers, etc) are installed correctly in Windows 10 and "fastboot devices" recognizes my phone, I am using the IMEI for SIM 1 to get the code as instructed by Sony, I just can't figure it out.
Am I missing something? Any advice would be appreciated.
Thanks.

Looks like the same error as in a previous thread. Try this: https://forum.xda-developers.com/t/my-device-cant-be-unlocked.4351405/#post-85822247

Thanks, I tried all the options listed on the thread you provided but nothing works...
I also saw the original poster for that thread never responded if they were able to unlock the bootloader successful or not so I contacted them and will follow-up here if there is a solution.
In the meantime if there are other ideas or others that have a solution please provide it.
Thank you

I run Debian Linux as my primary OS and unlocked and rooted that way. For that step, I got the tools I needed via: sudo apt install adb fastboot
