D4R-II binds, V8R4-II doesn't!
I have an X9D and recently bought an X9D+ which was an EU LBT version. As I already have a fair few receivers I decided to update openTx and install the non-EU firmware.
I have installed openTx 2.2.1 and flashed the firmware to opentx_X9DP_mode2_nonEU.bin (file date Wed 30 Dec 2015). However, as the title subject says, I can bind my D4R-II Rxs but not my V8R4-II Rxs (using D8 and the same binding technique of bridging pins 1+2 and switching Rx on).
Any pointers to what I could have done incorrectly please?
Thanks in advance
Dick

Can also add that the firmware is X9DP_2.1.6

V8FR-II, and several (7pcs) V8R4-II I binded successfully with several versions of opentx(2.1.1-2.2.1) with the internal RF module of Q7X.
Of course shorted ch1&ch2, power to Rx, [bind] operation in menu for curent model, 2nd page
Of course only "D8" mode for internal RF

Re: D4R-II binds, V8R4-II doesn't!
That's what surprises me. I use D8 and still the V8R4-II does not bind.
Anybody have any theories on this "impossibility" ? I have to be doing something wrong! Is it possible the internal RF module I installed is incorrect? Is there a checksum and a way to check it?
Help!

When binding: red LED flashing, next red off and on green LED?
At me green LED very often blinks, it is possible to tell or a weak glow. )))
If binding happen, but Rx non responded, then cause there may be different unsuitable settings. I had incorrect parameters for the Trainer mode. try to play them.
Try other type Rx.

The Rx just does not bind. The only time I see a green led is when I try binding it without pins 1+2 connected, and I get a single green led flash when I release the FS switch. It's really frustrating. Thanks for the idea.

V8R4-II have delicate antenna. check it.
On all my V8R4 & V8R4-II receivers it was broken off. soldered the antenna from other Frsky Rx's (spare from HK). or made himself of a thin coaxial wire. The braid is soldered to the GND (capacitors opposite the pad for signal conductor)

Re: D4R-II binds, V8R4-II doesn't!
The Rx antenna is not the problem. I have since bound the V8R4-II to a non EU D9X and flown the model. It was fine and had full range.
Today I tried flashing the opentc_X9DP_mode2_nonEU.bin file from X9DP_2.1.6.rar using the bootloader method and the radio initially reported that the firmware was incompatible. I tried a second time and it apparently succeeded, BUT, it has effectively bricked the radio, showing a corrupted opentx boot screen and hanging. The only way to switch it off is to pull the battery.
I saw on a YT video that there are rumours that frsky have blocked downgrades to non-EU on recent radios.
Does anyone know how to tell if this is indeed such a radio?
TIA

Re: D4R-II binds, V8R4-II doesn't! [SOLVED]
To overcome the problem above I used Companion to re-flash the firmware.
Having read on another another thread a suggestion that the Tx needed to be at least two metres away I moved the Tx to another room and both Rx bound faultlessly.
Thanks for your help.
