[question]T-CHU7AEAC_002005

[shahr774]

is T-CHU7AEAC_002005 firmware for UA40B7000WR compatible with samyGo. it is not in the compatibility list.and samygo f/w patcher 0.24 has problem with it

[erdem_ua]

Because SamyGO doesn't known at UA region. You needed to advertise us at there!

I can add compatibility. But if T-CHU7AEAC 2005 is restricted firmware? (preFeb 2010?)
For example could you connect your TV via ExLink?
Or can you run Telnet enabler from Content Manager?

If you can send the firmware link I can inspect it and found the problem. Could add to compatibility list later.
Thanks.

hi erdem I read many of wiki and forum sections and in exe.img of my original firmware THERE IS NO #remove engine logging BUT THERE IS
export KF_LOG=/dev/null
cd /mtd_exe/
./exeDSP
and this is why the patch is not running because there is no string to find. my question is ca I add the code manually to exe.img ?
I attach the exe.img opened by hex editor of my original firmware.and the whole file is downloadable in samsung global download in malaysian english site when you select UA40B7000WR as the model.unfortunately I am not allowed to add link.
I can telnet with my TV and FTP works .I did not make Exlink cable yet!!

You don`t need to rewrite the hexcode

Here is firmwareT-CHU7AEAC-2004.0, dated 28/10/09, so it is definitely preFEB firmware.
What strange i inspected there, the directory inside the archive is T-CHU7DEUC, but identificators are T-CHE7AEAC.
Will check exeDSP for firmware version, i wish it is not fake.

EDIT:
This firmware xored with T-CHU7DEUC xor key and exeDSP contains the string T-CHE7AEAC-2004.0.
I think this is quite normal firmware, feel free to use it on your device

And yes, exeDSP does not contain any #remove engine loging string to use with SamyGO patcher.


I also checked another AEAC firmware (T-CHEAEAC-2005.0.exe) and it has T-CHL7DEUC directory inside and all identificators for T-CHEAEAC. Seems this is normal praxis by samsung and models are very very similar.

dear juuso thanks for all your kindness. but what is the use of this firmware if i cant use patcher to load samygo.sh automatically at start up. with T-CHU7AEAC_002005 I can telnet with TV and FTP works.and i can use samba shares .but I want to patch exe.img for using automatic startups and everything else.

[juusso]

If i was you, i would risk and feed the T-CHU7DEUC-3000.G to TV. It should accept it. But here are some risks to brick TV.
I don`t know what could happen, but at least ExLink cable and shell access (checked and working), u-boot menu access also is must have before to making such cross-flashing.

Why does it needed? If you really want auto-start of applications, this is the chance to get it. If success, you can flash the patched T-CHU7DEUC firmware and get all benefits of using samygo.
If brick, having ExLink isn`t any brick dangerous (almost).

p.s. i will flash the T-CHLAEAC, which i found is currently being T-CHL7DEUC, to my TV and check what happens

p.p.s. After flashing TV started normally, but menus became slow. I see, the settings were reset to factory defaults in service menu. Even tuner was set for Asia_ATV

Conclusion: you could try to flash EU firmware, but probably TV becomes slow. To know exact what happens, needed to test. Be sure you have telnet enabler on TV`s memory and after flashing go to service menu and change rs232 to "debug", watchdog to "off"
