i have just flashed the 55.00.16.Rev.522 firmware on my TAT100.
After that I wanted to flash the BlueNRG firmware as well but it doesn't work.

I tried it via the Configurator and via Fotaweb.
In the configurator it hangs on initializing target firmware flashing and in fota web it says it was successful but when I connect the configurator it doesn't show a version on the info page.
It should be Firmware version: 10.X.X   55.X.X but mine only says Firmware Version:         55.x.x

The device also gets no GPS Fix and tells me the battery is 0 V.
Only the test connection button works, but sends an old entry. (RTC is not synced....)

Can some please help me?
Thanks Alex

ok I tried to debug as far as possible:

The configuration utility updates the 55.00.16.Rev.522 firmware all the times.
When I try to update the BlueNRG the tool hangs at "initializing target firmware flashing"

After that I have to disconnect the usb cable to get a connection again.
I debugged it on the serial port and it hangs after the command @asset_transport
the device replys with "ASSET TRANSPARENT MODE." and than nothing happens.

Can some please help me to get it working again?

Could you please provide this device IMEI? And have you tried replacing this device's battery?
Please check if the TAT100 battery is plugged in and attach the dump file if possible. ( It can be done using Teltonika Configurator -> Maintenance -> Dump )

Best regards

Sorry for the delay, the battery died before (1. battery had inverted polarity)
I removed both batteries and applied a fixed power source for testing.
Imei: 352625695264687
Device is currently switched on.
Dump files:  dump dump2

Any news on my problem?
Otherwise I have to get a new testing device - I want to test under real conditions (on the sea)
and that's only possible in July/August


I suggest you contact the Teltonika sales manager in your region about this issue, It needs a deep investigation, troubleshooting, and further information should be provided,

Actually, I saw in the dump file that The device's power was taken from the USB cable, Not from the battery which is shown 0 voltage, and for this, the modem may not function properly.

Note: Since the battery had inverted polarity, This will cause hardware damage to the device and may no longer be usable,
