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

here there're the dump.bin and the s1fwx extractor screenshot about the file extraraction

rar file in the attachments

Currently, your player only displays hourglass, is this correct? If not, the following information will be incorrect.

Extracted BREC from the player shows same connectivity as the models I listed above. LCM controller is the same odd one as in XY-1.8B.

If your hardware is not damaged and the information you provide is accurate, you may try this firmware. It should work:

my brother says to me that when the mp4 is booting it show a hourglass and after a logo,finally you can use the player
I tried the firmware but the display is still not working

Read DEAD PLAYER RECOVERY GUIDE for how to force HARD ADFU mode. Flash the provided firmware to the player.
