Help me find the TDM code for the F and H series. 20089999 not true. I can’t enter the TDM with 20089999.
If you managed to enter TDM with code 20089999, tell us how to make it.
I can’t enter the service menu using the remote control, some parameters got lost and the TV became a brick, but RS232 was turned on DEBUG and I can enter through it but the code 20089999 is not perceived.

You cant do anything in tdm to gain your problem solved. Better try other methods to access service menu.
As I understood your tv is operating, you just can't access service menu and change required values?

Optional eeprom reset might help.

Yes, I can not enter the service menu through the remote control, the TV freezes and reboots. But by disconnecting the block One Connetc, I can enter through the ExtLink, unlock the console witn code 20133697, but then the code 20089999 does not open anything.

Interesting. I know, TDM main menu is empty, that`s why you don`t see anything there.
you have to wait a little until we publish rooting method for F series. Currently it is is in early alpha stage.

Code for console unlocking is in kernel`s cmdline (SELP_ENABLE=...)

Code: Select all

cat /proc/cmdline
console=ttyS2,115200 root=/dev/mmcblk0p8 rootfstype=squashfs LX_MEM=0x40200000,0xC600000 LX_MEM2=0xA5E00000,0x1A200000 EMAC_MEM=0x40000000,0x100000 Onboot  : 0059.B SELP_ENABLE=20139120 quiet 
and TDM code exists inside exeAPP, xored. 20089999.
managed to do something after that ?

The problem is resolved. I bought a CH341A programmer on AliExpress for $5, saved my firmware, uploaded someone else's work, changed NUM OF POWER RECORD from 1 to 2, considered, compared, found this byte, fixed it in my own, uploaded it back and it worked. I stitched through the clothespin without soldering, although I had to tinker with the contact, write, read and compare several times to get the same result.
At the same time I found where the TV serial is registered in it and also restored it.
I also checked with another firmware, consisting of only 0xFF, with it the TV starts up and offers to manually restore everything in the service menu.

do you mean EEPROM content "consisting of only 0xFF" will make the TV to offer the option of restore everything in service menu?
