First of all, I would want to mention that the thread is from Mi A3, but since the community was too small to expect some help, and since I believed this issue could be affected to some Mi A1 device, I need to come over here to look for some hope. Thank you for understanding





I tried to flash stock rom through MiFlash after a few time sticking with custom ROM, didnt notice the default option was FlaSH aLL aND lOCk, and I am now stuck at fastboot. When I checked the command fastboot getvar all, it gave me 2 results, locked bootloader ( of course ), and active slot : B. After looking for some information, I knew that slot b could not be able to boot into stock rom and slot a could not boot to custom rom, I didnt notice that and totally forgot to change the slot, and the only option to bring my phone to life is to change the active slot to A. I belive the rom is still alive, it is just remaining some where in slot a. Is there any possible way to bring my Mi A3 back to life in any cost, either EDL or anything else? I tried EDL method ( no test point anyway ) but it gave me a big damn " cANnoT rEceIvEd HellO pacKeT ". I'm afraid no matter how many times I flashed, either in fastboot or in EDL, the active slot will stiill keep remaining b and never return to a without a bootloader unlocked, which mean the phone will permanently be bricked. Any hope for it? I will be appreciated

In my opinion, make sure the ROM that you use for flashing is not corrupt, use the latest Miflash because according to my experience on, MI A1 version of Miflash must match the ROM version, and make sure the USB cable/port You use in good condition
