Hello everyone,
The other day i bricked my T95M S905 box while i was fooling around with TWRP recovery. So the box froze and when i unplugged the power and plug it back all i got was the blue light on the front. No signal on TV. Nothing on the front screen.
So i googled the problem and found many guides (mostly from this forum) that explained how to unbrick the box. So this is what i tried and DIDN"T work:
1. Toothpick method
I tried several times to boot with the reset button pressed but still nothing. I also tried different power supply with no success. No recovery screen, no signal on TV.
2. USB Burning Tool
I tried to flash the firmware using AMLogic Burning Tool using the OTG port of the box but the box was not showing up on pc. I also tried on a different PC but i could make the box to show up on device manager. Some people had success while short pinning some pins on NAND but my NAND was a FORESEE NCEMASD9 and there was very little info about this NAND. Anyway i went for it as i had nothing to lose and short pinned 17-18 pins but nothing happened again. I also tried to short other pins but no success at all. I luckily didn't destroy the NAND.
3. BootCard Maker
I found a spare 2GB sd card and created the SD card using this tool with the correct uboot.bin file from the T95M firmware but nothing happened again. Still only the blue light. I also tried another sd card (1GB) but this didn't work either.
I decided to hook up the USB UART cable that i had, to watch the console while booting. IT could give me a hint. The console output was:
...EMMC:0;READ:0;CHK:F3;SD:0;READ:1000;USB:8;LOOP: 1;EMMC:0;READ:0;CHK:F3;SD:0;READ:1000;USB:...
on the loop. With or without the SD card i was getting the same message. I read somewhere that this message indicates that it can't find the bootloader. So i tried many different firmwares and uboot.bin files from many sources but still nothing.
Finally, when i was sure that my box will never be unbricked I FOUND THE SOLUTION! i tried BootCardMaker with another SD card from my Raspberry Pi. A SanDisk 16GB Class 10. I plug it in the T95M and TADA! ! ! Bootloader was loaded and the Android Robot was on the TV screen with the word "Upgrading".
So if anyone is trying to unbrick his tv box but had no success this is the lessons I learned:
1. The T95M tv box probably is not supporting the USB Burning Tool method.
2. Try different SD card from different vendors.
I hope this post will help people that have the same problem.
