I have TV dongle which looks like UG007 from outside, but inside 'Netxeon MK806 V30' string can be found. Unfortunately it stuck now on Finess 1.5 IMX1/2 boot logo. The progress bar of it usually is animated, now it is all red without any movement.
When trying to do 'adb shell' I get:
bash-4.1$ adb shell
- exec '/system/bin/sh' failed: Exec format error (8) -
I'm able to run into recovery mode, flash mode and normal mode (where boot logo stuck). I tried to reflash the device with boot, kernel, system and recovery img's to Finless 1.4, 1.5 and 1.7 with rkflashtool w/o any success. Every time result was same - stuck on boot logo. I can boot into Linux placed on SD card after reflash to proper boot.img then the device is working. Looks like NAND died (?) but how can I prove it? How can I do any diagnostics to check if NAND is broken ???
