I have 2 Abbree GMRS-9Rs. I was aware of the Channel 15 No Tx, and that there was a upgrade fix when I bought the HTs. I didn't realize it would be so hard to find a English upgrade instructional video or the files.
I found the Upgrade files on the Abbree Upgrade page. My Anti-Virus blocked the download. I don't read Chinese and the video seems to skip some of the steps. I'm hoping someone has a easier solution to this problem. Thankz!!
