Hi,
Readme about flashgrade:
------------------
PLEASE SAVE YOUR EXISTING CODEPLUG AS AN ARCHIVE FILE. The codeplug programming
information may be lost after the update process therefore, it is recommended to read the
radio using the CPS, and save an archive of the radio's codeplug before starting the update
process. After the update, this archive can now be used to recover the codeplug programming
information by programming the archive back into the radio.

Ensure the radio updating process is not interrupted. Interruption will cause the radio
not to operate anymore and attempting to update the radio again will NOT be successful.

Do NOT create a shortcut of the program (e.g. on your desktop), the program might not
be able to find the data files in that case!

Do not remove the programming cable or turn off the radio while the update is in progress.

In case of failure during the updating, a message box will appear to guide the user to
recover from the failure, if possible.

The flashing rate can be changed only by restarting the program.

You may not run more than one copy of the program at the same time.

Baud rate 115k can only be supported by certain Radio Interface Boxes (RIB).
Use 19k baud rate when using a RIB. RKN4075A RIBless cable supports 115k baud.

maybe you found the answer because the post is old, but I'll through my 2cents anyway, maybe someone else is interested in the future.

Times ago I bought a ribless cable from eBay, and I was able to read/write codeplugs but not to flash/upgrade. When I researched more deeply, found that the ribless cable does not have the BOOT pin. So I manually added (extra little yellow pin, soldering, etc) the BOOT pin, and now I am able to do everything with the cable. Pay attention thou, that not every cable can do. As I learned after the procedure, it depends on the chip the cable was built with. Actually, I was lucky, at the time to have bought the right cable without knowing the different chips were used. Today I had a look at eBay and found that actually about 99% of the cables on sale can do the trick. I'm not able to provide the links to those cables because maybe it's against the forum rules.

To manually make the flash/upgrade-able cable, you need an extra golden pin, soldering stuff, and a lil patience. For schematics you can always use the good-old batlabs.
