X4R r/x firmware help please

[davew]

Hi,
After 10 years of Spektrum I switched to FRsky at the beginning of the year. I bought a Taranis plus from T9 Hobby in the UK and have accumulated receivers since.

I have 2, V8FR-11 running on D8, 2, X8R running on D16, and a D4R-11 on D8.

Until the purchase of this X4R everything has been good. This r/x won't bind with the Taranis. I established a mismatch of firmware. I don't want to change the Taranis and have been trying to flash the X4R for compatibility, so far without success.

I know how to reflash using the T/x and so far have tried 4 different files in the r/x and none will allow it to bind with the X9D Plus.

I have tried:
X4R_140521.frk
X4R-X4RSB_cppm_eu_150624.frk
XJT_141016.frk
X4R_LBT_build15118.frk

Can someone tell me which file I need and where I can obtain it?

I rang T9Hobby and he didn't know. He confirmed that my radio was not the new 2016 spec but 2015 spec. He suggested You Tube videos but I've watched them all. They tell you how to carry out the operation (which I know) but don't tell you what file to use or where to obtain it.

Can anyone help? PLEASE!!!!

If your radio doesn't have yellow LBT stickers you'd most likely want
X4R-X4RSB_cppm_eu_150624.frk

No my radio doesn't have the yellow LBT sticker - to be fair T9 Hobby asked me that.

I'll try that file again but it is one on the list that I've tried. Maybe I made a mistake somewhere so thanks.

Then that changes things - if the radio doesn't have the LBT sticker it can most likely be reflashed to non-EU.

Thanks Kilrah. So I'll try the file you recommended again.

Hi Dave

Have you tried the videos from Drone Shop? https://www.youtube.com/watch?v=AnDTJ0bwG2E

Various files are available somewhere on these links

Many thanks Kilrah. I tried the file you recommended again and this time it worked!!!!!!!!!!!

Just shows. I must have made a mistake with the binding afterwards. I'm now confident to order a couple more of these receivers. Great forum.
