bricked LA46A550P1 help!!

Post by madmike » Mon May 26, 2014 7:11 am

hi newbee here
I've got a LA46A500 this is bricked :cry: I did this by changing the settings in the service menu not knowing what i was doing
power on 7 blinks of the standby led black screen and after about a minute it restarts and repeats over and over
1-tryed the eeprom chip tick on the only 8 pin eeprom on the main board- didnt work
2-this board is a mt8226 so tried re-flashing with MtkTool and when i hit the flash button it says "baudRate AutoSet Fail! Please reset the target board" and the baud rateis set to 115200
3-trying to work with putty. I've communication with the board but it restarts before I can do anything meaningful

has anyone got any experience with a A550 board that can help, would be appreciated

i think your brick should be repairably by eeprom reset. You have to identify SoC eeprom and make short connection on it.
