Yes, you have a big chance to recover your TV.
You can stop bootloader with `~` first...
Also there is a wiki article shows you how can you replace your FW with Serial Cable.[
1] So reading will make you understand the how flashing made.
Since new Firmware does not install new kernel or root image but only exe.img and appdata.img partitions, you can get in to linux shell and make changes that you required. (like old partition)
Experts will help you further soon if you needed. I advice you to look wiki pages generally.

You can use any other comment or empty space in the /mtd_exe/rc.local file.
People may be able to give guidance as to what you could change insted, if you post your version of the /mtd_exe/rc.local here.

I think no one understand problem.
cttm does not alternate rc.local file. It flashed original LE32B650T2W FW instead of LE32B650TIR.
So
nothing to do with rc.local files.
Can any one show how he revert his old firmware?
----------------------------------------------------
First step is get down to the Linux Console, read this article.
http://wiki.samygo.tv/index.php?title=E ... 2B_Devices
Once you stoped exeDSP and killed MicomCtl, you can go with second step.
dynamic will show how to recover old flash images that stored in your TV. Will you dynamic?

Hi cttm,
normally there is always a backup of these critical partitions available, which can be booted in case of such issues.
We should try this out first, before attempting to reflash the corrupted partition.
You can enforce booting from the backup flash, by switching the appropriate boot-flag through
Code: Select all
rm /mtd_rwarea/PartitionSwitch_0_0
touch /mtd_rwarea/PartitionSwitch_1_0
This is obviously assuming that you have access to your serial console via exlink cable ( see the link erdem_ua has shown in his post ):
Try this out first and if this doesn't help, then we can try out the next steps ( erdem, yeah this forum is there to help
.
