USB not working after upgrade

[24ariel3]

I have ua55b7000 tv and stupidly I upgraded it with ue firmware (t-chu7deuc-3001.1)
and now the USB is not working at all
I tried to get into u-boot and TDM without any luck, I typed debug and get this

[SERIAL INPUT MANAGE] 1-th ENABLE Magic serial input match!
[SERIAL INPUT MANAGE] 2-th ENABLE Magic serial input match!
[SERIAL INPUT MANAGE] 3-th ENABLE Magic serial input match!
[SERIAL INPUT MANAGE] 4-th ENABLE Magic serial input match!
[SERIAL INPUT MANAGE] 5-th ENABLE Magic serial input match!
[SERIAL INPUT MANAGE] serial input ENABLE!!!!!

after that I tried to type 1198282 but nothing happend.
one more thing, I get a lot of I2C errors in the debug

Something I can do to fix that?

Thank you,

Yes, this is the problem. But i have few ideas!

1. Perhaps it is enough to change USB ports count in service menu? Go to service menu ([MUTE] [1] [8] [2] [POWER]), be very careful, buttons right-left change options, you can navigate trough menus ONLY down/up!
Go to control-config option. Take camera and take photos of every screen you enter (in case you change something accidentally).
What is meaning of num of USB port ?

2. If your Internet@TV works, you can install this widget. Use our DNS or install custom widget from your http server. btw, check this topic as well viewtopic.php?p=43073#p43073

3. I remember here was exact same problem with UAxxB6000. User got TV working i`m not sure you can repeat same steps, but you can try if widget way fails.

I know one user who soldered missing usb socket (with some missing resistors) to the mainboard and got it working. But this method is not for everyone, right?

Sorry for the late reply I was afk

In the service menu the number of usb ports is set to 2

The only thing I can work with is internet@tv I have a little trouble with making the hack work, I need to spend more time on reading how to make it work, but I need to know something it says the hack works on UE tv and may cause brick to other models. Mine is UA is it safe to apply the hack?

I have a network hard drive recognized by the tv in the dlan menu. Is there something I can do with that?

[juusso]

install widget and use "activate alternative firmware" option. after this go to menu help software update and choose it. your ua tv is ok.

[24ariel3]

tnx

I can't make it work. I can see developer settings under gallery widget settings but I don't have there and option for entering an IP BTW the developer settings are there even if my profile name is not develop.

what am I doing wrong?

[juusso]

I think you need samsung widget engine. Use our DNS and check internet@tv. let it be upgraded...

WOW!!!
I managed to enable the alternative firmware and roll back to the original firmware of the tv and now USB is working!!!
THANK YOU, you are great!

p.s
With your dns I can't use the widgets in internet@tv and with network sets to auto internet@tv wont load.
How to make it work?

My firmware now is
T-CHELEU-0103
T-CHU7AEAC-2005.0
T-CHU7DEUS-2005

I can't acces u-boot or exlink or telnetenabler I guess this firmware is not pre2010, what what is the latest pre2010 firmware?

BTW is it possible to load the firmware as a virtual machine on a pc? it is a linux isn't it

[juusso]

Which way have you used and succeed?

To get u-boot & co working, now you have to launch FFB with pre-FEB firmware. BUT! T-CHU7AEAC firmware is not supported by FFB. If you are ready for testing, i can prepare it for you (if we find required firmware on the internet). What is needed for beginning - use dump maker and give me all files for inspection (upload to any online storage and give here the link). Thanks!

I used this dns 149.154.159.134
and started internet@tv right away it started to download widgets after it finished I entered "hack your tv" and there I selected the "activate alternative firmware" afterwards settings>upgrade firmware>alternative firmware and that is it, I waited for it to finish and it rolled back to a good compatible firmware.

update
I run the Dump Maker but i can't see any process on the screen, I see just the picture of the DeLorean is that ok?

[juusso]

yes, wait until delorean disappears. then check usb...
