I presume, that I have bricked my OTT TV BOX Model: M8S. I flashed OpenELEC from this link via USB pendrive (recovery method):
http://amlinux.ru/image/5.0.8/OpenEL....arm-5.0.8.zip
After flashing my device is almost dead. Almost, because USB Burning Tool (I have tried several versions, included most recent)
is recognizing device correctly, but flasing is impossible. After 9 seconds flashing process stops at 2% and i can hear sound
from Windows like disconnecting device from USB port, and connecting after few seconds. This "flashing" process never exceed 2%
and always stops on "Download DDR" status.
There is no indication (device has only one blue LED on front panel) on front LED. Three different USB cables has been checked,
on two computers (both Win7 64bit). Drivers are installed correctly.
Error code is:
[21:51:29 539][HUB5-4][Err]--usb_get_configuration ret=-5 error_msg=sending get cached configuration ioctl failed, win error: [Device is not connected]*
[21:51:29 539][HUB5-4][Inf]--Failure : 3, FailureMax : 3
[21:51:29 539][HUB5-4][Err]--[0x10105002]Romcode/Initialize DDR/Read initialize status/USB Control setup error
Images 3, 4 and 5 show flasher app status.
I have tried all possible firmwares from many sources, none of them boots from SD card. I assume, that I'm making bootable SD
card correctly:
1. BootcardMaker,
2. Choose u-boot.bin from firmware package.
3. I have tried two SD cards (32gb and 2gb) with FAT32 and FAT file system formatting with different sector size.
4. After formatting all files from firmware archive has been copied to SD card.
PCB (top and bottom view) of my device (red circles is my mod): attachments 1 and 2.
Look at silk layer: Top layer says that is M8 V8_6, bottom sticker says M8S.
Before bricking, I have checked processor with CPU-Z: S812 has been recognized.
Questions:
1. Is there any person on this forum, who have exactly this device and have flashed it correctly? If yes - with firmware did You use?
2. Do I have a chance to dump entire flash via UART from identical, unbricked device and send it to bricked one?
3. Do You have any suggestions (maybe different SD firmware) to revive this 50$ coffee holder?
