Thank you and good day

I just tried the tutorials its does not work ... I'm still stuck on the Asus screen ...

if you stuck on ASUS logo screen, boot twrp once, it would solve this problem.
download stock from asus site, and flash with stock recovery.
twrp didn't support stock firmware.

my Redmi 3S is bricked?

I unlocked the BL and flashed an International Developer MIUI two years ago, and it has been working fine.
I want to flash a stable ROM now. the miui website gives three approaches (system update, recovery update, fastboot update).
I first tried system update, but the system cannot proceed.
then for recovery update, volume up + power button enters Teamwin (TWRP), not the recovery interface shown in the official guide.
then fastboot update, unfortunately the MIFlash tool does not recognize the phone in fastboot mode.
so I went back to TWRP, clicked Install, and installed this ROM: http://bigota.d.miui.com/V9.2.1.0.MALCNEK/miui_HM3S_V9.2.1.0.MALCNEK_fe706c31c4_6.0.zip
which I saved to the phone storage earlier.
now the phone is in a bootloop , stuck at "mi" boot screen. somehow I can still enter fastboot mode, but I don't know what I can do to save it.
please help me , thanks

Trying to make guide for that
I just resently came out from hard bricked

Device Boot Looping/Soft Brick

I decided to unlock the bootloader so that i could flash TWRP recovery but after unlocking the bootloader on my device, it has been stuck on the logo screen with "powered by android" under it. I have tried using fastboot to clear userdata & cache but that just leads to my phone again being stuck on the logo screen. The device also can't boot into recovery. When I chose to power off in fastboot it causes me to be stuck on the logo screen. Any help is appreciated I am on android oreo btw

Did you try a back to stock zip? go to fastboot and run flash-all.bat, while your device is plugged in ofcourse.

Click to expand...
Click to collapse
Let me guess.
You unlocked the boot loader and flashed TWRP and now you are looping, right?
There is no compatible TWRP that is compatible with Oreo on this phone.
You cannot leave TWRP installed. You can only install it along enough to get the recovery to boot.
You then must flash the stock boot image.

I had this problem tonight also. In my case I suspect it had to do with the install of magisk in which I checked both boxes and patched the bootloader. on reboot I was stuck on boot. Just wanted to add my solution. I got the pie back to stock zip here https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681 then I put it into the adb folder and ran the flashall.bat script. I tried the no wipe one and it saved my information. very happy I didnt have to resetup my phone in the end.

did you remember to flash a stock boot.img before flashing magisk (to clear TWRP?)

BRICKED ASUS ZE552KL unlocked fastboot mode not found cant install recovery

I used TWRP to flash official lineage os 16, it was working fine but a new update came and it booted directly into recovery to install firmware. It could not install it . I was stuck in recovery. when I flashed my backup of lineage os it indicated some error saying /system not found. I then searched over and run some command in unlocked bootloader fastboot to fix it. I found a thread on xda to fix system error in TWRP and run cmd "fastboot erase system "also erased boot and recovery then clean installed boot and recovery but my bootloader was gone.
Now it's stuck at powered by android only and with no asus logo. I used asus flash tool with raw image file
to get into stock rom but failed.
THE UNLOCKED BOOT LOADER IS LOST
when I press volume up and power key the system bootloader comes but the deafult bootloader and the unlocked screen message is not showing.
and when i press only the power button there is no asus logo the phone is stuck at screen saying "Powered by android"
please help !!
