EraseFailed when flash a unirecv, Error code: 49

[kahoch]

Hi, When I trying to flash firmware into a logi unirecv, got error 49. Any idea? Thank you!

[kaho@arch uniflash]$ sudo ./uniflash.py flash keyplus_nrf24lu1-unirecv-0.3.3.hex Found a supported device with bootloader: (0x46d, 0xaaaa) flash_start?: 0x0000 flash_end: 0x63FF block_size: 0x0200 ./uniflash.py:450: DeprecationWarning: tostring() is deprecated.

What does uniflash info give you?

[kaho@arch uniflash]$ sudo ./uniflash.py info Found a supported device with bootloader: (0x46d, 0xaaaa) flash_start?: 0x0000 flash_end: 0x63FF block_size: 0x0200 ./uniflash.py:450: DeprecationWarning: tostring() is deprecated.

And you've run uniflash icp to get it into bootloader mode?

[kahoch]

Yes, run uniflash icp and then uniflash info.

Hi, @angustrau I missed an error when I run uniflash.py icp, 😓

[kaho@arch uniflash]$ sudo ./uniflash.py icp
Traceback (most recent call last):
  File "./uniflash.py", line 366, in <module>
    enter_icp()
  File "./uniflash.py", line 107, in enter_icp
    detach_kernel_drivers(dev, [0, 1, 2])
  File "./uniflash.py", line 48, in detach_kernel_drivers
    if dev.is_kernel_driver_active(i):
AttributeError: 'NoneType' object has no attribute 'is_kernel_driver_active'

This is similar to Uniflash Issues #40, @Merlin04 said

if I replace the uniflash.py icp with keyplus-cli bootloader, it solves the is_kernel_driver_active issue

but if I use keyplus-cli bootloader, nothing happen, then I use keyplus-cli list, seems it can't find the unifying receiver. And after uniflash.py reset , the receiver still in bootloader mode. The origin firmware had been erased?

[kahoch]

Solved. That receiver come with a signed bootloader. I bought a new one. @angustrau Thank you for your help!
