OpenWRT on Philips Hue Bridge, probably brick

Hardware Questions and Recommendations
1

Hi, I recently bought a Philips Hue Bridge 2.1 from an auction site. Received it today and the does not work, only one LED is On when connected to power. Started browsing the internet, changing the ethernet cable, ports did not help, the reset button did nothing. Decided to solder pins to the board plug it into the UART, connected via putty and this is the result.

Suposes the bridge is a brick, can anyone know how to unbrick it.

Thanks for help

This device is not supported by OpenWrt, so it's probably running some vendor fork, thus asking on this forum is not the best action. Anyway, I'll assume someone wanted to port it to official OpenWrt and failed, leaving device in broken state.
Judging from FCC photos the Hub has two flash chips, one NOR SPI and one NAND SPI. Bootloader seem to be placed in NOR flash while the rest is in NAND. Bootloader doesn't seem to report any bad blocks on NAND flash, but taking failed CRC check of kernel image into account, that is very likely the problem. The second possibility would be broken/interrupted update, which could result in failed boot. In both cases You'll need firmware copy to recover and writing it to NAND flash. Might be that vendor implemented some kind of fallback for failed firmware write (very unlikely since it fails anyway), so checking U-Boot environment and help output could give some clues. Check this blog post: https://blog.kleine-koenig.org/ukl/philips-hue-bridge-v21.html how to access U-Boot command line. Maybe @ukleinek has more to say about the device, since that's his site.
Good luck.
