No firmware available now it says when I try again? Can someone check on server what the logs are saying?

Thanks

Ok needed to factory reset, but the only firmware available to me is the firmware I'm already on, 1033.2? Any ideas anyone?

Can I downgrade via usb somehow?

libDowngrade.so is available for E/F/H but it silently supports D. Just one thing - we have never tested it on D and here is big chance for brick.

Server sometimes needs to be restarted, we have some issues with stability.

In state not anymore, I've disabled D support to protect the innocent, but there are only 2 lines to uncomment in sourcecode :)

My test board has some customized rootfs, that`s why i failed testing on D series arm.
However, the first part of downgrade procedure was ok: injected lib did the trick and patched everything correctly. TV was able to find lower firmware on usb and initialization of downgrade procedure started successfully. Lib needs to be tested on normal (not customized like mine) D series arm. I bet 99 percent it will work even if in my case TV bricked (explanation above why).

If someone brave enough to try it on D series, i think SamyGO will spend mainboard in case of brick as a compensation. Chance for brick exists, but big chance for success. @erdem_ua ?

Hello I have an UE55D6000 tvm with firmware T-GAS6DEUC_1028.0.

i do not know if the firmware is the problem or a defective motherboard ... but my CI+ it is not detected anymore.

The menu in TH is also greyed out.

Can you guys, please help me downgrade this firmware ... or do you have some kind of fix ?

I have setup the DNS as mentioned but when search " No firmware is available".

Thank you!
