    That's interesting, so, are you able to back original firmware? Does it come with AT command line flashed?
    Helpful post? Buy me a coffee.

    not yet tried.

    it should be noted that the BKWriter dump is junk and has partitions in the wrong place or something. BK Easy Flasher dump is OK. I will try flashing back soon.

    hang on. yes, it must. half the HLK-B30 PDF from Hi-Link goes on about it in relation to whatever the image is they ship these with

    Yes. Original fw dump flashes back and boots after erase/flash OBK-T

    @akosschneemaier did you ever get a dump of your module? I'd be interested to flash to HLK-B30 if you did.

    thanks. I have flashed your dump and the HLK-B30 has booted!

    can't find any bluetooth or wifi AP after several resets, which I was hoping would put it in pairing mode. I'm using the Arnoo app too

    Ah. AiDot app finds it

    Should I be querying it for anything? Did you flash HLK fw to your B30 module @p.kaczmarek2 ?

Topic summary

The discussion revolves around flashing OpenBK firmware via OTA using the Tuya Cloudcutter tool. Users emphasize the importance of verifying the actual chip on the PCB, as Tuya has been known to ship devices with incorrect labels. The flashing process involves downloading the correct firmware, running a script, and ensuring the device is in AP mode. Several users share experiences of flashing issues, particularly related to incorrect firmware versions (T vs. N chips), and the challenges faced when devices fail to boot. Solutions include using the detach script to identify the chip and attempting recovery mode for re-flashing. The conversation also touches on the CC8000 chip, which appears to be a rebadged BK7231U, and the need for different firmware for these variants.
