VideoAR Fix - Display Size

[mprotect]

So you don't need modified firmware to run this? Could this same method be used for 3000 firmware? And is it the v1 or v2 AR fix?
David

It's the v1 fix. You don't need to modify the firmware. And the enabler itself doesn't modify anything in flash, either.
I don't know the 3000 firmware. But modifying exeDSP or similar in main memory should be possible on every device which lets you run a program like this.

it was no waste of time to leave the fork code sample in telnet enabler

Well, I used the source from "SamyGO Telnet Enabler v0.01.tar.gz" . IMO releasing code/information is never a waste of time.

Here comes the fix v2 for T-CHLCIPDEUC-2005.0.

You should copy the files to the tv storage. After starting the fix the filesystem where aspect.so resides cannot be unmounted.

hi,
this i call motivation

may it's possible to combine a table with function names and addresses for different exeDSP versions (think erdem may have the infos already?)

tv type and firmware version is readable from /.version or /.info & /mtd_exe/ReleaseInfo

in theory the hack is the same for all versions and change just in function name and address, correct?

tnx a looot

Thanks for the code.
But I prefer more portable code.
Ho can we make it compatible with other exeDSP's?
We needed to think about one patcher fix them all for automation.
Thanks

Right.

Well, I had portability in mind when i did the patch. That's why I replaced CToolMmbDisplaySizeItem::GetToolItemTextData and CToolMmbDisplaySizeItem::PressLeftRightKey totally. However, the later one calls an other function with some unknown addresses. So its a little bit questionable whether it works on other firmware versions, too.
The third function is more difficult. For example there's a call using a pointer in it. So i replaced it only partially. But there are changes that it works on other CI+ versions, too.
The CI and CI+ code differs a bit, I think the CI+-code has been compiled with -fstack-protector or something similar.
So maybe one needs two versions, one for CI+ and one for CI.

I think we can run 2 different executable from one unified, small script at run time
Thanks.

I attach a test-version of the avrfix 2 for T-CHL7DEUC-2005.0 (CI). I cannot test it. Try it on your own risk.

Edit: Attachment deleted.

Tested it. My Model LE46B650, Firmware 2005.0.

Thanks for testing and posting the results. Next try:
