when you unlock, unlocktool will make backup file,, if you still have it, you can restore it after ubl, then you can get your sim signal back, put phone on fastboot, plug on pc and push "Write backup" on qunlocktool, you can restore this on any rom and will not erase data or anything.

Hi, i cant see the screenshot... I will try to guess whats happening.
Do you mean that you tried to do a factory reset from the settings menu?
If so, and you have twrp, it wont work. You have to do it through twrp

I dont have TWRP, I use default bootloader, wanna change but cost is high,,.,
You can use Verizon software upgrade tool on your PC and reinstall the stock software. There will be an option to erase all data.

Mi8 bricked

Hello guys, i try to explain the problem.
I had Mi8 unlocked, then i download from xiaomi.eu the last release 8.8.30 and TWRP. I flash recovery in fastboot mode and flash rom in TWRP, in that momento the phone cant boot, stuck in loading screen.
Trying to solve I install MiFlash to flash a chinese stable rom, in that moment the screen turns off, my PC recognizes the phone and the MiFlash too but always black screen. I choose two pics, one shows like the PC recognizes the phone and the second pic shows the error i have now in MiFlash with black screen.

i have the same issue
Guys! Problem solved, i contact with s-unlock.com and in a few minutes the work was done and the phone its alive.
After flashing TWRP you could probably just have done a format data (where you need to confirm with yes) (so you get rid of the encryption, it's the issue why you can't boot), still in TWRP transferred the rom to phone and then flashed it and it would probably have booted fine.
But glad you got it running again.

Cannot unlock bootloader again after using Clean and lock option in XiaoMiFlash

Hello.
A friend ask me to install Lineage OS on his Mi8 so we asked for BootLoader unlock, wait about 15 days, unlock it and install Lineage OS.
But he decide to try Havoc OS because of some missing features in L.OS but flash goes wrong.
I manage to reflash MiUI 8.11.23 to get a usable phone but I didn't notice the option in the lower right end of the screen and I flashed with "Clean and lock" option
So the bootloader is now lock again but we cannot unlock it as when I use myflash_unlock utility, I'm facing this error :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Is it possible to unlock again the phone ? Do we have to wait for a some days (like when you first unlock it) ?
Thanks.
If you used your xiaomi account to unlock it, then you should be able to do it again instantly (something similar happened to me and I could re-unlock it without problems). If you do not have the account that was used, you have a big problem and only one solution: go to a Xiaomi store and ask for a reparation, they have EDL accounts and that will fix your problem. You can try to find a EDL account on internet, but it is almost imposible.
If you are using your own account, maybe you can try with a wipe data, but I am not sure
PD: remember to check if you have activate the developer options of USB debugging, etc. on your device

it's rooted i think so
if you are wanting network signal...try and remove magisk by clicking the uninstall button on the magisk app
or
reflash the system rom using odin...make sure country matches and you get the correct firmware version. I highly suggest this...coz it is assured to work.
