(03-04-2021, 08:10 AM)donVito07 Now I'm able to access fastboot, but lots of commands can be executed

your bootloader is locked, you won't be able to flash using fastboot
you'll need to use edl and flash firmware specific for tiffany

At last, I figured out that my device don't even be Mi 5x, but worst, it's Mi 5X Oxygen. Now, with locked bootloader, I put the device into EDL and flash 5x firmware ( with emmc_appsboot.mbn of Oxygen ), but I tried many version of firmware, it only can boot into Mi logo screen and then stuck there. Some versions ( chinese stable MIUI ) can boot into 1st setup screen but no reaction when I touch the screen ( vol +/- can still applies and make changes, thats weird ). Some other version can boot through the Mi screen but then the screen becomes blank while the 3 navigation buttons is still useable. Really, I tried to read many articles but still not find out what's really happened with my devices.
Any suggestions would be appriciate.
Thanks!

the version that gives the blank screen with the 3 button still working, can you pull down the notification bar?
and have you tried firmware for the other two variants? ie Tissot and Rossy, at least you can rule out tiffany seeing as the bootloader isn't even compatible

Basically, this device started with Tissot firmware on it, Rossy I haven't try, but that may a good turn, will give it a shoot!

Sorry I didn't make it clear, what I mean when saying "it started with Tissot" is when I bought the phone, it was running on Tissot firm bro. If now flashing Tissot firm, it's gonna stuck in 900E again

are you referring to the same device you mentioned was "back to life" @ https://www.hovatek.com/forum/thread-384...#pid211002 ? or a different device
if what you say is correct then you might want to check the emmc chip of the device

Correct, its the same device. Update the situation now is that after managed to flash a mix firm ( of Tiffany & Oxygen ) then the device is working now. It turn on normally, booted in to system, everything works perfectly ( included 3 navigation buttons ), only that the screen is total black. The computer recognized it as Mi 5x, can boot into fastboot and execute commands ( but the bootloader is still locked ) and else.
I guess maybe the screen is death after to many experimental, or maybe another reasons that I haven't known yet.
Can you please suggest?

you could play around with the files, swapping each partition one after the other to see if any will fix the screen, what i mean
e.g you flashed partition 1 with tiffany, try the file for the same partition from oxygen instead
