LRS Backpack version update problem.

[FieryOwl]

Hello everyone.

I have the following situation.
I have RadioMaster T15 with Bandit Micro ExpressLRS 915MHz RF Module at the back.
The Radiomaster has EdgeTX V3.3.1 firmware version on it and the bandit has 1.3.0 version Backpack DUPLEX_TX_BACKPACK firmware version on it.
I do the following procedure. Through LRS Configurator i build a firmware version for 1.5.4 version Backpack, for the exact hardware device that i have. Then enable the wifi from the RC and connect to the ExpressLRS TX Backpack wifi networ and then when i try to flash it trough the browser it says that has mismatch the version (img1 that i provide. Sorry for quality it is not on my computer and taken with my phone).
Or if i have the correct version it has error 4 that says not enough space.

I have seen other suggestions to downgrade the version and try again but i have the following question.

1.3.0 version Backpack has Target: Device category TX and Device: Duplex TX Backpack( that is what i gave now)

1.4. version has few radiomaster Target but at the Device menu there is no Duplex variant or no Bandit variant
should i use generic backpack.

I think if i have to go from version 1.3 to version 1.5.4 for example i have to go through 1.4
But which Target device: Radiomaster or what?
And which Device?

Or should i go with 1.4. version Device category: Generic Backpack for any TX module
Backpack for ESP32-based TX module?

And after that to 1.5.4 version Device category: RadioMaster; Device RadioMaster Bandit Micro 900Mhz TX

Or in general what is the right procedure to update the backpack firmware itself.

I i cant see the post, contact me on [email protected]

Ok found out why I couldn't upgrade it. My computer didn't have the driver and couldn't recognize the module.
After I installed the right driver it connected successfully and I could build a 1.5.3 version backpack firmware and upgrade it on the module through the browser.
