Can't remove screen PIN from A546E/DS


Got two identical phones with screen Pin code, the first one entered to recovery mode without any problem and code has been erased... The second doesn't want to get recovery\download mode at all. I tried everything, 3-4 cables, a few laptops (even with Chrome OS ) and got nothing. Phone accepts SIM cards and get the network without any problem. I opened it unplug the battery for an hour, but it didn't help. All keys work fine, type c port also. What could be the problem with the phone and how to solve it? Here some info from it

Code:

For sure. It's not a SIM PIN code, just for screen unlock. Here is the photo ...

Thanks for your info )
I don't have Chimera Tool, gonna try to find someone with it in my region. TP is working on this device.
Seems like this is some kind of new device protection, I've never heard about that.
