I have used GD77transfer.py to upload codeplugs to several GD-77 and DM-5R+ radios without problems.
My latest version is attached in this post:
Re: Read/write GD-77 codeplug in Linux in Python 3 (experimental)
There is also another script, gd77xfer made by LZ1CK. I have not tried it.

Re: DCS audio cuts out
I have the same problem with a new Baofeng DM-5R Plus with firmware OpenRD5R (built Jul 31 2020) when listening to a signal with CTCSS and excessive deviation. Several other radios tolerate excessive deviation without problems.

Re: [Fixed] RX CTCSS does not work...
I have the same problem with GD-77 with OpenGD77 release 20200507: in a FM repeater which sends CTCSS, stations with strong audio (wide deviation?) cause severe stuttering which makes it impossible to understand.
I started using OpenGD77 from release 20200411. I think it did not have this problem?

Re: Read/write GD-77 codeplug in Linux in Python 3 (experimental)
CPS works fine with Wine 5.0 in Fedora 30. Menu texts are visible normally. It's very easy to install Wine and use CPS in Linux: # dnf install wine $ wine OpenGD77CPSInstaller.exe Install as usual, except no USB drivers, because USB does not work in CPS with Wine. Then execute CPS from the Wine menu...

Re: Read/write GD-77 codeplug in Linux in Python 3 (experimental)
In the attached version there are two changes:
- Change delay in serial communications from 0.2 to 0.0
- When reading a codeplug, initialize first 0x0E bytes (which are not read nor written from/to the radio) so that CPS is happy
No changes in usage, see "./GD77transfer -h".

Re: Read/write GD-77 codeplug in Linux in Python 3 (experimental)
CPS (MainForm.cs, function openCodeplugFile()) checks the first 8 bytes of the codeplug file that it opens. Those 8 bytes must be FF or contain the current radio model. Otherwise you get error "Model does not match". So I should set all gaps that are not read from the radio as FF - is that enough? T...

Re: Read/write GD-77 codeplug in Linux in Python 3 (experimental)
I still don't know what the data in the codeplug is file that I read from the radio is incorrect I copied the logic for reading the codeplug from GD-77 from function worker_DoWork(), case READ_CODEPLUG in file OpenGD77Form.cs. That piece of code leaves gaps in the codeplug file: def getMemoryArea(s...

Read/write GD-77 codeplug in Linux in Python 3 (experimental)
I have written a program in Python 3 to read and write GD-77 codeplug in Linux. I have tested this program only with my own GD-77. Before trying this make backups! Usage: $ ./GD77transfer.py -h GD-77 Data Transfer v0.0.4 Usage: GD77transfer.py [OPTION] -h, --help : Display this help text, -r, --read...

Re: Codeplug EEPROM 128 byte alignment when uploading from CPS
File OpenGD77-master/docs/data_sheets/Atmel-8720-SEEPROM-AT24C512C-Datasheet.pdf says: "128-byte Page Write Mode Partial Page Writes Allowed" When I look at file OpenGD77-master/firmware/source/hardware/EEPROM.c it looks like function EEPROM_Write() handles 128 byte boundaries so that the caller doe...

Codeplug EEPROM 128 byte alignment when uploading from CPS
I have looked at function WriteEEPROM() in OpenGD77Form.cs. The function uploads EEPROM data to GD-77 in chunks of MAX_TRANSFER_SIZE (32 bytes) but on every 128 byte boundary it begins a new chunk. Why is this necessary? If we begin a new chunk every 32 bytes, a new chunk will be started every 128 b...
