I checked your files and here is a hope for you. Wait.

I make detail step by step for you, because i have here some doubts. Could you please make/buy ExLink cable and connect it to TV? With cable you are insured if you brick TV.
I do not care a lot about program`s name. It could be FFF too, why not,...erdem_ua wrote:juuso. I think we needed to change this program name. "Back" doesn't fit here much.
Force Firmware Flasher fits better doesn't it? ( FFF or Fx3 or F^3)
This program not simply enables alternative frmware as you said, it reboots directly to it (in condition - flashing was successful and no errors were). We could remove alternative fw option to activate post-FEB firmware (it goes as alternative after restart)...Who can say then, that FFB activates alternative firmware? I understand - you take care about safety of process. It is more safe to use FFB as playing with linux console, dexoring by phyton and so on if user just could copy/paste without knowing what does he do. Most of our users are on about very basic or zero linux knowledge level. So automatize firmware downgrading process from scratch to finish is that, what i`ve expected in februar 2010 after i flashed stupid post-FEB to my TV and i believe most of FFB users are happy with this. What about some TV brick we got after FFB0.2...Sure here was. But from v0.3 safety is improoved (mandatory restoring deleted u-boot usw, killing exeDSP) and i did not her about any brick yet.Also if this program "enables alternative firmware", we needed to remove that property, split this in 2 piece.
Why should we use two apps instead one for downgrading? I think it`s irrational to use few apps if you want downgrade your firmware if it could be done by one app. Especially if there was no alternative fw on TV at all before (TV purchased after FEB2010)One program for just enabling alternative fw, (which is safe) and one for force update.
You get error due firmware mismatcherdem_ua wrote:For example what if I put a firmware with another name, like trying to burn T-CHL7DEUC instead of T-CHLCIPDEUC ? Does it brick our TV? Or just got error firmware mismatch ?
