USB not working after upgrade

[juusso]

if lucky, tv accepts firmware and installs it. But I think tv is blind for this firmware and will not find it on usb at all. Nothing bad if you try.

I feel uncomfortable to risk and brick my tv especially now when everything is working well.
Thank you for everything.
It took me 3 years to attempt and fix my usb problem, so I will definitely try and make this one day

3 years. OMG

yeah 3 years... I served in the army for the last 3 year and I had no time to deal with it
here is the T-CHU7AEAC-2004.0 (maybe there is someone out there that needs it or will need)

ha my TV says that it recognizing a valid upgrade 002004, and leting me to downgrade to 2004.
How to make sure that this is actually 2004 and it compatible with my tv?
last time I did an upgrade I lost my USB for 3 year because of a wrong upgrade

[juusso]

it is named right way (T-CHU7AEAC) , big shance downgrade will be ok. If not, you always can use our widget...

[24ariel3]

correct me if I am wrong, firmware upgrade can't cause a brick because it just updating some files and not replacing the whole system?

[juusso]

firmware downgrade or upgrade rewrites few important partitions, not full system. But if error during procedure (usually - blackout) occur, this can lead to the brick. And in this case if you don't have working uboot - you get trouble. That's why I gave you those files. For insurance if something goes not as expected .

[24ariel3]

but these files rewrites important files too aren't they?

[juusso]

yes. just bml5 is important and critical key for success. bml2 and bml4 are important for uboot. now those two are empty at you

briefly: copy paste commands one by one and everything shall be ok.

[24ariel3]

Ok so I did

bml.restore /dev/bml0/2 /dtv/usb/sda1/bml0_2_dump
sync
sync
bml.restore /dev/bml0/4 /dtv/usb/sda1/bml0_4_dump
sync
sync
bml.restore /dev/bml0/5 /dtv/usb/sda1/bml0_5_dump
sync
sync

all completed successfully.
After that I just applied 2004 firmware from the usb and it worked!
Now I can access TDM


But still I cant access internet@tv with my provides dns

update:
I managed to get i@tv to work by setting network settings manualy.

now I have difficulties with synchronizing my widgets from my ip
