Use the above guide to unlock the bootlader using mtk client. No region change or in depth test apk are required. The guide works perfectly but I ll give you some advice in order to help you as much as I can.

1. At steps that you connect the cable with the side volume keys both pressed the phone is like connecting and disconnecting. You ll hear the familiar sound of windows, when a device connects and disconnects. Just ignore it and type each step's cmd command given by the guide. It's hard cause you need to hold the volume buttons all the time while you paste the command and hit enter!!

2. After every step that requires the above procedure, when you finally release the keys, boot up your phone!! Because if you try to connect again by holding the volume keys it just doesn't work. It seems that the phone gets stuck every time you do this and in order to boot up the phone you need to press all the volumes together for a while (vol up + vol down + power button). The phone seems to be bricked, doesn't power on, doesn't connect to pc with cable and this could scare you to death but if you do what I say, (pressing all together keys until the phone vibrates) then it will come "back to life"!!

3. Don't forget to apply the "filter" as the guide describes. If you get any errors, you need to rerun the wizard (write filter in the search box in windows and you ll find an exe called filter wizard) and select uninstall all filters. If you get again any erros try unistall all filters again until you also get no erros. And then install the filter again until you get no errors. This is important and it might be tricky.

4. I used another mtk cmd for lock and unlock bootlader to avoid writing the command. In that "exe" you had choices like press 1 to unlock press 2 to relock. Something like that. With this cmd that I used and I think also by writing the commands on my own to the cmd, when I unlocked the kernel the phone did not boot up. The solution is to get manually in recovery mode and delete and format data. After that the phone boot ups completely normally with unlocked boot loader. So an extra step to the above guide is that after unlocking the bootloader the phone doesn't boot up, get into recovery mode and manually wipe/format data. This of course means that you re going to lose anything you have inside your phone. Both settings and personal files.

5. Don't be scared by the orange state and/or red state messages. If you are on android 11 you ll receive a notice about dm-verity corruption and you need to press the power button once again in 5 seconds in order to continue the booting process, else the phone will power off. It's important to remember that you need to press the power off once again in cases you want to get into recovery mode too. For example if you use adb/fastboot to enter in recovery mode (adb reboot recovery) you will first see the red state message, you need to press power button again once and then you will get into recovery!! The orange state will be always there forcing you to wait for 5 minutes until boot, unless you install a custom recovery and you flash orange state fix! I haven't done this.

So in android 11 both red and orange state warnings, in android 12 only orange state warning!!

6. I you want to get into fastboot mode don't try using the "adb reboot bootloader" command. It won't work and might mix you a lot. You will receive strange messages. Try "adb shell reboot fastboot".
