downgrade firmware? #60

Closed janekska closed 11 months ago

janekska commented 11 months ago

I have UV-5R PLUS with k5_4.00.01 version firmware. I can't flash any modded firmware - I am getting kind of version control message:

Warning

The file version is not match!

OK

I am using Portable Radio Update tools v.1.1.12

Are there any options to downgrade or how coul I get modded firmware on newer radios?

Please follow this instruction file_version_is_not_match.md and let me know if it helps.

janekska commented 11 months ago

O, thanks a' lot. I successfully flashed to k5_2.01.27.

But mostly what I am interested in are in version ...26 and then there is the same error message.

After flashing k5_2.01.27 you should be able to flash all fw with version starting with v2.*

Nope: image

In previous message it is a bit wrong screenshot. Probably the program in the background did not released com port. The resulting message was the same: image

Please attach your k5_v2.01.26_mod_001.bin here, I just checked exactly your scenario and it totally works.

k5_v2.01.26_mod_001.zip

I was able to update with this mod from telegram group: uv_k5_plus_26_spectrum_v58.zip

amnemonic commented 11 months ago

ok, that is really strange. uv_k5_plus_26_spectrum_v58.zip presents itself as 4.00.01

what only I can suggest is following:

That also indicates that bootloader version is important for flashing procedure. At least for official update utility.

I want to install version 2_01_26 on UV 5R plus, any firmware does not install it

ok, that is really strange. uv_k5_plus_26_spectrum_v58.zip presents itself as 4.00.01

what only I can suggest is following:

  • download file qsfirm.py
  • place it in same folder with k5_v2.01.26_mod_001.bin
  • run command: qsfirm.py unpack k5_v2.01.26_mod_001.bin fw.dec.bin fw.ver.bin
  • edit file fw.ver.bin in hex editor to start with 4, for example 4.00.1
  • run command: qsfirm.py pack k5_v2.01.26_mod_001.bin fw.dec.bin fw.ver.bin k5_v2.01.26_mod_001_but_as_v4.bin
  • after that you should be able to flash k5_v2.01.26_mod_001_but_as_v4.bin

That also indicates that bootloader version is important for flashing procedure. At least for official update utility.

this works just perfect if change the second part after editing in a Hexeditor the Version number the command from unpack to pack
