Well, first of all, I'm sorry, I haven't encountered this kind of problem.. I flashed E2 and it was solved in one go.

LZ, you should first use your mobile phone on your computer. Check if it can be flashed normally. If it cannot be flashed, uninstall the driver. Then reinstall the latest universal driver

If yours can be flashed, but your friend's cannot be flashed, then go to normal mode. Connect the computer to see if the computer can recognize the phone...

If the computer recognizes the phone in normal mode and a removable disk appears on the computer, but still cannot flash the phone, it is recommended to go to moto after-sales service for upgrade. Haha. Oh, the upgrade is free

I believe that if moto after-sales service can upgrade it, you can flash the phone...

moto will not block the program

Also, a new flashing package was released in Russia yesterday - Kaleidoscope. Recommended to the original poster

A lot of flashing... Haha
