[TR6260S1/FL-M61 V2] WiFi Smart Switch how to change the firmware?

Hello, I own the relay shown in the pictures. I have soldered out the WiFi chip to show it and to try to change its firmware. Now the question is how and with what to go about this? I am doing this for the first time I can't find any information on this. Is it possible to upload Tasmota or SUPLI? I am interested in what can be uploaded here, not a replacement for another chip. USB to TTL I have a YP-01, thank you in advance for any hints.

Hello, I'm afraid this is a completely new chip, which hasn't appeared even once on our Electrode list yet:

A quick search on Github also shows that there is no SDK for it, or at least that's my impression.
EDIT: This is the only result from the Github search:
https://github.com/Akeeta/Akeeta-SDK-TR6260
but very poor there...

At this moment I don't see the possibility to change the firmware of this module. The only thing left is to check the pinouts and do a replacement with ESP02S or similar (pinout equivalent of TYWE2S, WB2S, CB2S...)

Quote:

This module can replace modules such as: CB2S, FL_M99_V1, TYWE2S, TYZS6, TW-02, WR2, WB2, WBR2, WR2E, WB2S, WA2, XT-BL02

Of course when replacing you would also have to check that the pins match for sure, paying special attention to RST and so on.

You can keep the old WiFi module, maybe you can find an SDK or something new will appear.... you can also try to connect to it with the UART and at least collect its log (if it prints any log on the UART), I don't know, but in the log maybe there would be some additional information about the SDK used.

Added after 3 [minutes]:

There is something about the SDK, but it's in Chinese...

@dawkoh there is now a backup and flash tool and an OpenTR6260 firmware that can be flashed to these modules.

If you're able to follow the new guide to back the existing firmware, that would be very useful.
