I haven't tried your model but I believe it is impossible to brick tlsr82xx with software manipulation.
Use 'ea' command to erase flash and try again with BLE firmware

После прошивки Zigbee необходимо использовать выход RESET при запуске «активации» в любом программаторе!

Прошивка Zigbee полностью отключает Flash во время выполнения в режиме глубокого сна и настраивает защиту от записи во Flash.
В результате прошить простейшими программаторами без сброса микросхемы с помощью RESET или переподключения питания во время "активации" невозможно.

Сброс питания может не сработать, поскольку чип, находящийся в режиме глубокого сна, получает достаточное питание с любого выхода, включая вывод программирования.

This firmware doesn't support MJWSD05MMC yet. You need to add screen management and (possibly) define different i2c group for your device.
But I suppose the connection should be similar to 03mmc:

  1. GND
  2. 3v3
  3. TX --> 1kOhm -> SWS (near rx on the board)
  4. RX --> SWS directly

@devbis Thanks.

I tried to connect it as you mentioned and flash the original firmware, but no luck, put the battery in doesn't boot up. I think it's bricked.

Thanks again for your help.
