Description
https://www.baofengradio.com/products/gt-22
Can read from and write to the device using the latest daily build with Baofeng BF-888 driver via CH340 cable. GT-22 should be similar, but with less features.
Original CPS program from Baofeng reads, but does not write the channels properly.
Debug.log, screenshots and initial CPS configuration attached.

As you have discovered, being able to read and write from a particular vendor/model selection does not always mean that the selected driver module is appropriate for a particular radio. Does the OEM software for the BF888 work with your radio? My guess would be no, as well.
This radio looks very close to a Retevis RT22 (not the similarity of the name). I would expect better luck with that being a closer match. The "magic" string that initiates cloning is not the same to so it isn't worth trying because it won't work.
I have hacked up a test driver module just to see if you can read the radio. Choose Vendor: Baofeng/Model: GT-22. If successful, attach the downloaded CHIRP Radio Images (*.img) file to this issue so further research can be done.
Instructions for using the test driver module.
- save the test driver module to a convenient location (do not right-click to download)
- open CHIRP
- click Help and then enable Enable Developer Functions
- click File -> Load Module and then locate and load the test driver module saved in step 1
CHIRP should now have a red background to indicate it is running with an external driver module loaded. It does not permanently change you CHIRP installation in any way. I you close CHIRP, you will have to load the test module again to use it in the future.
Now try downloading from your radio. If successful, attach the "image" file. If unsuccessful, describe the error and include the debug.log file. The test driver module will download only. It has no upload or settings capability.

Thank you, Jim.
Followed your instructions, downloaded the image successfully.
Unfortunately, unlike with the BF-888 module, only memory locations 4, 8, 12 and 16 are loaded and no settings available, see attached screenshot. Both image files are attached as well.
As I mentioned earlier, my problem is that the original software does not write to the radio properly. CHIRP with BF-888 module can read and write the modified data back, just that GT-22 has less features, as compared to GT-888.

Yes. I know. I disabled the uploads and settings because I am only interested in looking at the memory of the radio to see if I can recognize a similarity to another radio I have seen in the past. The good news is that I think I do recognize something, but I don't remember which radio it was. I will try to look around after supper to see if I can find it. If I can, I should be able to come up with another test driver later.

As suggested, I have tried the original software for Baofeng BF-88E (PMR version of BF-888). (I was surprised that together with their V12 software they also bundle CHIRP v.20180519) It also reads and writes GT-22 successfully.
GT-22 just lacks the GT-888 options like wide/narrow, scan, side key etc.

Have you tried the Vendor: Retevis/Model: H777 Plus selection? That is the radio with the memory view that I remembered seeing before.

Yes, it also works with the Retevis H777 or H777 Plus driver. It just does not have the scan/alarm/side key functionality.
Baofeng GT-22 is a twin of Retevis RT22 or RT622, but their drivers do not work.

Then would you try using the Retevis H777 and/or Retevis H777 Plus Vendor/Model selections in CHIRP to download from your radio. If successful, attach the CHIRP Radio Images (*.img) files here.

I don't see any settings for the side key on the GT-22 programming software.

Here is the image done with the Retevis H777 option.
GT-22 has no side key, no scan and no alarm functionality.

Thank you. Is this what you are looking for?

Just got this radio. Not available in Chirp Next. Any progress?

I worked on this a year ago but nobody got back to me with feedback regarding my test driver. Without any testing, I couldn't submit the changes to add support. Since I don't own the radio (and don't plan to buy one) someone with the radio has to participate in the development.
Unfortunately the proposed driver above was for the legacy CHIRP. So it can't be just dropped into CHIRP-next. I would need to re-investigate and recreate the the work in a format that would be compatible with CHIRP-next. If I invest time in this a second time, are you willing to stick around as long as it takes to test it to completion?
