Rbwap2nD not flashing

[KlenKlenov]

Hi All! We got a new batch of mikrotiks RBwAP2nD-BE. I have not managed to flash them with standard firmware openwrt https://openwrt.org/toh/hwdata/mikrotik/mikrotik_rbwap2nd_wap.

Also it was not possible to make the latest version of the repository. Up to this point, all previous devices were flashed without problems.

I decrypted the file supout.rif, 03_.proc board=wap-hb. Board is present in the MIPS-ath79-add-routerboard-detection.patch patch. I connected the UART USB converter to RX, TX, GRD.
I configured putty 115200 and did not see the bootlog. Device license level is 4.

I used the wiki https://wiki.mikrotik.com/wiki/Serial_Port_Usage to configure the serial port, but I could not create a port in the winbox.

After flashing mikrotik with the openwrt-ar71xx-mikrotik-rb-nor-flash-16M-initramfs-kernel.bin, it stopped pinging and the AP/CAP LED constantly flashes.
LEDs PWR and ETH are constantly on.

Please, could you tell me, how to define the problem with this device? How else can I get a bootlog? How to configure serial port?

Regards, KlenKlenov.

Another found the difference between these two models. Those who reflash without any problems have an inscription on the box:

Those who do not reflash have an inscription on the box:

Have any idea?

Or maybe the device is protected to flashing? How to find out?

Did you get anywhere with this?

I have the same problem, the system boots from the openwrt-19.07.7-ar71xx-mikrotik-rb-nor-flash-16M-initramfs-kernel.bin but after flash it becomes a brick.

will you be able to dump memory from a device that works? Maybe the bootloader is checking signature / signature. Perhaps you only need to replace the bootloader and it will be OK.

Hello! Create a dump with a programator? Or cat /dev/mtd4 >> /tmp/backup_fullflash.bin?

I have already solved the problem. I will add support for this router for ath79, I just need to fine-tune a few more thread.
