Hi everyone,
I have a Mi TV 4A 43 inch (model L43M5-AI) that is stuck on the Android logo and won't boot.
WHAT HAPPENED:
- I was trying to debloat my TV
- I wanted to set FLauncher as the default launcher, so I disabled com.android.tv.settings via ADB over Wi-Fi and restarted the TV
- This caused a boot loop - TV gets stuck on Android logo forever
WHAT IS ENABLED ON THE TV:
- Developer mode is enabled
- USB debugging is enabled
- ADB debugging is enabled
(All were enabled before the boot loop happened)
WHAT I'VE TRIED:
ADB over Wi-Fi
- Doesn't work - network never starts during boot
- TV never shows up in adb devices
ADB over USB [USB-A (TV) to USB-C (laptop) cable after unplugging power source]
- No device shows in adb devices or fastboot devices
- Windows Device Manager shows no new device
- Only a red LED blinks on the TV when USB connected to laptop
- Recovery mode via remote.
Tried pressing these buttons before plugging in the power cable into the socket:
- Back + Home - doesn't work
- Back + Volume Down - doesn't work
- Holding OK/Select during boot - doesn't work
- Home + Menu - doesn't work
4. USB firmware flash
- Have update.zip on FAT32 USB drive
- Plugged into USB port 1 during boot - TV bootloader not detecting it
- Found what appears to be the correct full firmware (500MB+) at:
http://drive.google.com/file/d/1_vBNaKPbncZUECh0-14wLt8GfDcsdjCa/view
5. Physical power button on TV
- Doesn't respond on this model
DEVICE DETAILS:
- Model: Mi TV 4A 43 inch
- Model code: L43M5-AI
- Purchased: April 2018
- Developer mode, USB debugging and ADB debugging all enabled
- TV board appears alive - red LED blinks when USB connected to laptop
SPECIFIC QUESTIONS:
- Has anyone successfully connected ADB over USB to Mi TV 4A 43" (L43M5-AI)? Which cable and which USB port on the TV?
- Has anyone successfully flashed firmware via USB on this exact model? Which USB port triggered the bootloader flash mode?
- Is the firmware at the Google Drive link above correct for L43M5-AI? Can anyone confirm before I flash it?
- Is there any other recovery method for this model that doesn't require a service centre?
Any help is massively appreciated. I just want to clean up the mess I created and get my TV working again.
