These different versions are confusing... My headunit came with an app that styles itself as "TLink version 5.2.6", is that the same branch as the zlink5-dingwei firmware linked in this thread?
My version is definitely usable, wireless as well which is great! But there are some quirks, like clock/temperature randomly not displaying or switching units, touches sometimes not registering or lagging. Also looking forward to Coolwalk, but I guess it's not active on my phone yet.
Could I update from "TLink 5.2.6" to zlink5-dingwei-release-v5.3.4 and expect it to keep my license?
Can I downgrade and have my current version working in case the new apk does not work out?
I am quite worried about loosing the license, that would be like bricking the head unit. Does it keep my license if I stick to the same branch?
Is it worth it to try out other versions than tlink 5 or and will they just never activate?
