That's why I suggest now to backup deviceinfo.
Another deviceinfo will not work! Later if I have device I will find combination of partitions to make unlock, but sorry not now

But I have managed with twrp flashed as boot.img for 7.1.1. and 8.0.0 (later new version) with my version of bootloader file, custom rom (root,etc ) work even on locked bootloader state.
With "yellow" warning message on boot screen.

Yes it is wiped, And is it very bad? What problems this will cause?

Who stuck on OTA update 2040CN with locked bootloder
You can try this boot to get temporary root. Note this will erase unlock key from deviceinfo too.
I'm not sure if this methode will run on locked bootloader, but you can try

1. Download this boot file, unzip
2. Use fastboot command: fastboot boot patched_boot_recovery_Android8_sharp_nokia.img
3. If its ok you will see yellow message on screen, after, in Android you can install Magisk get root and replace "abl" and "xbl" bootloader with older version (unpack my nb0 firmware). Then run 135E nb0.

This methode I made to downgrade from Android 8 on unlocked bootloader.

Pls check

What fw version do you have right now?
Here you can download latest official global FW for 6/128 version: http://dl.sharpmobile.com.tw/update/...B01-update.zip
If you have 135 "with letter" that stands before "F" in order of alphabet, then you can flash this latest version without any file name corrections.

1. Download fw.
2. Copy it to the root of the internal memory.
3. make factory reset before flashing global (if you have CN version)
4. Open "phone" app and type: *#*#874#*#*
5. You will see "upgrade" button. (If no, then you need to rename fw file - just replace "135" with "136")
6. While upgrade process it is possible that it stops for some times on 40% - just wait.

You can see, that it is official build if you look at the download adress.
Here is the link to the page, where you can find this download link: http://www.sharpmobile.com.tw/服務支援-s2
It is Taiwan official support page. Use google translate
"WW" in file name means - global, instead of "CN" - Chinese.
"SAT" at the file name - means 6/128 version, "SS2" - 4/64 - be carefull, when select what to download.
