UE32D5700 boot loop mistery...

[alhyene]

Hello, 1st am new here and wish you happy hacking TV's or what ever...

Bad news, I think I've bricked my UE32D5700 RS XZF (update MST5DEUC_1027.0 - 24/06/2015)

I've try the code to go inside service menu (HOME / MENU / MUTE / POWER) with TV switched ON and saw a grey menu which not fit entire screen and by accident I touched the remote and screw up something I don't know...

Looking here a way to un-brick TV by erasing EEPROM (SDA + RESET in my case), still no luck. (not try SDA + VCC nor SDA + GND or with SCL)

Before doing this, LED blinks, TV boot up with Smart Tv logo, HDMI-2 appear upper left (last time selected) and boot loop, but after un-brick procedure LED blinks, Smart Tv logo, no HDMI-2 on screen then loop again. (~20s)
Then I think EEPROM is somewhat reseted.

I will try other combinations like SDA + VCC, SDA + GND, SCL + VCC and SCL + GND but don't know if it's worth the case.

May be by unsoldering the EEPROM and re-program it, but no HEX file apart may be in the update. (MST5DEUC_1027.0) ?
MICOM chip memory altered ? NAND flash ?

All suggestions are welcome !

Any chances for me apart getting a new mainboard, worst buying a new TV...

DON'T LET CHILDREN PLAY WITH THE REMOTE

hi, all
No answers... No matter I'll continue my quest trying to make functioning UE32D5700... (and may be others !)

I've extracted the update(s) (T_MST5DEUC.1027.0.exe & T_MST5DEUC.1025.0.exe), decrypt them with the all-full samy's go pyPatcher script *WOW* and mounted them as squashfs.
There's lot of things inside update fs !!! Files 'Factory_Part1.dat' & 'Factory.Part2.dat', two others are 'SubMicomEU.bin' and 'SubMicomUS.bin' seems EU & US ((:)) for...
I got EEPROM and subMICOM files contents... But don't know well how to operates with, seems being EEPROM firmware split in two (Factory_Part1.dat' & 'Factory.Part2), and MICOM regional(US & UE for me)l, and what doing I with that ?

What could I try ? Some Help needed...

I will investigate again....
