Firmware issue on UNI-T UTi260B

[Mike1983]

Hello everyone,
yesterday I installed a firmware update on my UNI-T UTi260B.
Unfortunately, it now gets stuck at 100% during startup.
In the console, I receive the following message about every second:

Code: [Select]

imageListUpdate()
Cannot find the director
Regrettably, I don't have a backup of the original firmware.
That's why I'm reaching out to ask if you could send me your backups or firmware.
I would try them out in the hope that one of them works. Thank you in advance.

Best regards from Germany

One of several threads here in the forum with this issue:

https://www.eevblog.com/forum/thermal-imaging/uti260b-uti690b-firmware-backup-script

Several people have uploaded their firmware. You want to be sure you match the major version of your original firmware. This is usually a soft "bricking" caused by installing the wrong firmware version. For example, installing v2.x firmware on a v.1x device. This isn't officially documented and even Banggood provided an incorrect version that bricked my UTi690B (same as the 260B). Since you already have console access you just need to copy over the main firmware file back to your unit as described in those threads. Also the original splash screen image if you want it back.

Thanks!
I've found the needed version, my 260B is working again.

Hi,

u can find my backup here: https://cloud.ordnung.family/s/6eLp9qZJcsrYmj5

You have to copy the application and maybe some libs (check the update script that u used. There is a list of files which were updated) on a sd card.
Connect a RS232 (UART) to the camera (you have to open the camera). Which this connection you can open up a serial console to linux. Then copy the application and the libs from the sd card to the flash.

good luck

Thank you so much Mike for your support. I can't say I fully understand how to do it as I am not an expert as you. Still I did many ordinary repairs, so maybe it is time for me to learn new staff.

Just in case you had some free time, can you elaborate more. I will search for details on how to do each step. I am mainly talking about flashing the chip that holds the bin file.

Hi,
unfortunately in my 260B I  - thoughtlessly - tried to upgrade the firmware from version 1.1.6 to version 2. Result: soft brick. I don't have my backup... Now I connected using Putty and tried solutions from other threads (FWBackup):
 

cp -r /media/mmcblk0p1/FWBackup/etc/ /etc/
cp -r /media/mmcblk0p1/FWBackup/usr/lib/ /usr/lib/
cp -r /media/mmcblk0p1/FWBackup/ /root/

[/i]

Unfortunately it still hangs on "Loading ..." screen.
The link to your files does not work (error 404). Could you share your backup again and write a few words on how to restore it?
Best regards


Edit after 3 hours:

Done - I was able to upload version 1.2.6
There were errors in the copy commands.

Instead of:
cp -r /media/mmcblk0p1/FWBackup/etc/ /etc/
cp -r /media/mmcblk0p1/FWBackup/usr/lib/ /usr/lib/
cp -r /media/mmcblk0p1/FWBackup/ /root/

It should be:
cp -r -f /media/mmcblk0p1/FWBackup/etc/ /
cp -r -f /media/mmcblk0p1/FWBackup/usr/lib/ /usr/
cp -r -f /media/mmcblk0p1/FWBackup/root/ /

I'm not sure about the temperature calibration though.
And maybe is newer version FW 1.x.x is for the 260B ?
