SamyGO should have big banner on whole page "DO NOT UPGRADE", but I guess for some people it would be still not enough

Some people like myself found out about this project after upgrading to LATEST 3001.1! If I knew about SamyGO 2-3 months ago, then I wouldn't go for 3001.1.

So, why you go into upgrade at first place ? did samsung force you do, did they post changelog about improvements ?
There is simple rule about upgrade in many devices, if things works don't blindly upgrade.

and...?

Here is a way to restore u-boot partition via normal TV upgrade, but it did confirm with LE*B653T5W and T-CHL7DEUC 3000.2_step1 firmware. I did not risk to upgrade to 3001.1_step2 to confirm this method. Maybe anyone, who has the latest firmware upgraded can help us to provide some experiment - it is not risky to brick Your TV. Anyone?

hello how do I know if my TV with firmware 2005 LE37B650 has some error? I can not access the top menu ...... why? when I turn on the TV and makes writing and debugging boot is no longer active but then niente.come do I check if I did downgrate exactly, before I had the 3002 version

Your 2005.0 firmware hasn`t any error. You can`t access TOP debug menu and u-boot because of install fw 3000.2. Reverting back to 2005.0 didn`t restore the deleted partitions. If You want access Top debug menu You need to restore u-boot at first - partition bml0/2 (it is not necessary, but if you get problems after flashing kernel, it will be your key to restore TV. I would recomend to restore u-boot at first) and then you need to restore partitions bml0/4 and bml0/5 by flashing them manualy.

You can try to restore all three needed partitions via normal TV upgrade by adding required images to USB like i made here

Via this method were four TVs successfuly restored, but i can`t confirm, that its absolutely safe. I would recomend to add just u-boot.bin for first time to get u-boot working and with next try with Image and fnw.bin only (w/o u-boot.bin)
