[Solved] Sony KD-49X8305C Android Boot Loop Issue: eMMC Replacement, Easy JTAG Plus & PSU Board Advice

Hi

My Sony TV had the Android boot loop issue, so I replaced the eMMC (H26M52103FMR). The dump was programmed via Easy Jtag Plus. The dump went fine with no errors reported. When I put the board back, nothing happened—no power light. So instead of reballing the chip again, I found the pinout diagram on the net. I just ISP it again with another dump; still the same outcome, no power.

Did hard reboot, inserted new firmware via USB, still nothing.

Is there any other IC/component which needs replacing? Any help or advice would be appreciated.

Also changed the PSU board too.

Change the mainboard

for a new? used? programmed?

Can you Share dump working file?

Have you moved extCSD from the damaged bone to the new bone? Probably the TV is trying to start with Boot1 and it should with UserData.
