Area mp4 atj2091n
 

i have an Area mp4 player that is dead

chip:ATJ2091N
memory: Samsung 4gb
board: TCH B803 V2
display: GiantPlus kmf136i01-1a
fm chip: yes(i didn't use the radio so it isn't important for me)
battery:Li Ion 3.7V

please help me to find a firmware

Did you mean KFM136F01? That one has an Epson-compatible controller.

Matching display controller:
CM60026
XY-1.8C
KFM136F01

Matching connectivity:
B806
SCC91-002
MP-9820

At the rear of the screen i found GIANTPLUS KFM136I01-1A HXD
On the left side KGM136I0 0517-2 FR4118.1 A-KNB742315 03 10-W
On th right side WZ-KLM136I01-A 070525/5

KFM136I01? That seems to be a rare model.

Does the player at least get to the hourglass screen?

yes when the player was alive it show a hourglass,now i use the recovery guide but i didn't found any working firmware

Try extracting whatever is left of the firmware with s1res.

i've already flashed the player with other firmware without success, so i can't extract the original firmware

in the attachments i insert the cmd screenshot and the dump.bin made with s1fwx

It doesn't matter whether the firmware is original. As long as you get an hourglass I can determine display controller type and connectivity to recommend more compatible firmware.

i didn't use the original firmware i flashed it with firmware that i found in internet
