USB not working after upgrade

[juusso]

btw, our dns is designed only for emergency needs. Normal usage of widgets is impossible. Now you can use your regular dns...

yeah I thought so but with my dns internet@tv is not loading at all.
If dump maker freezes and not disappear will it brick my tv?

update:
it finished but the flash drive is empty... weird what can I do?

[juusso]

use fat32

[24ariel3]

Yes it is fat32. I just sarted it the wrong way.
Now I can see % moving on the screen

Tell me my friend maybe you know if it is possible to run tvs linux as a virtual machine and not be afraid of a brick?

[juusso]

IIRC no on B series. With uboot you can do NFS boot, but just rootfs and kernel. If you want boot full firmware, you have to make custom booting scripts... this require deep linux knowledge.

I see...
anyway here is the dump

how to use it in case of a brick?

[juusso]

at the moment here is no big help from dump. Later you can use them to restore tv if bricked.

[juusso]

I checked your dumps. As i thought, you have restricted firmware on board. I have required files to reflash, but just trough telnet console...
Start Telnet Enabler (check download area OR from FFB pack) and use EXACT commands:

Code: Select all

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

Just if no errors, you can reboot TV. If any error occur, give me result and don`t reboot TV!

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

I found T-CHU7AEAC-2004.0 (uploading) firmware it suppose to be preFEB. if I try to "upgrade" my tv from the upgrade option (in settings) what will happen?
