R270+ bricked, just beep beep beep :)

Hello,
my r270 acts exactly like that https://youtu.be/frJ4zySeBF0
It might be faulty U10 element which is ADESTO AT45DB161E - this is flash memory but wierd one. If you look at its datasheet you will know - not that i understand all of it Big Grin
I see minipro has it on the list(which is slightly diff AT45DB161D ) but partially i guess, so even if i ever get the dump i don't think it would be possible to write it on the chip.
Maybe someone has that memory for sell, ready to solder and work?
Maybe some other solutions?
Thanks in advane mates.

Yes, but it is still cheaper to buy the chip for $3 and flash it, if only someone share dump, then pay again $30 wait one month and end up with faulty device again.
