I tried all the existing protocols, and don't work. But I'm very confident the old and the new versions shares a lot of similarities.
Unfortunately the RF chip is masked, like all the Syma toys I have seen, but the encapsulate is the same as Beken 24xx
I will try to capture SPI traces at the old controller when receive my logic analyzer.
Probably, we could fly the old and the new version only including a minor option at the protocol.
BTW, I will capture SPI traces for the camera controls at the X11C, but probably Seby will receive before me

Did you see my question about the datarates and Syma protocols?
If it uses one of the supported chips and you can get an spi capture we can take a look

Just confirmed.
X11,X12,X5C-1 and the new X11C shares protocol
Including camera controls at X5C-1 and X11C.

If you have the X11-C version, and a logic analyser, here are the pinout I used to sniff SPI data

Thanks Seby!
You saved me a lot of work.
Unfortunately, my logic analyzer and my Syma X11C are on the way.
So if you plain to review the X11C, probably you will receive before me.
I confirmed the protocol of the Syma X11C is the same, because Quadcopter101 upload a video this morning using the X5C-1 transmitter.

Don't forget we need Hexfet after I sniffed data 
Mine is the easy part

Another post to say thank you for your work guys. Awesome!!!!
Just flashed my 7E. All protocols are there. Now need to wait for the bird to fly to me from China
Cheers.

Hi Folks.
Today, I received my Logic Analyser and tried to capture for first time.
Really, I don't know if I captured ok
This is a capture from the TX of my Syma X5C old version, not the new version X5C-1 under discussion at this thread.
@Hexfet.
Please, could you take a look in the hope the protocol could be very similar to this X11/X12/X5C-1 protocol? As I wrote some days ago, could be Syma only changed the datarate to increase range.
As I wrote previously, I don't know if I captured ok....
Removed SPI Capture
Finishing the capture, I activated the throttle down trim to start video capture, next throttle up to take picture, and finishing I push down throttle trim to stop video capture.
I have not received my X11-C camera version yet.
Thank you very much in advance!

I've quickly skimmed over your SPI trace.
Channel order is somehow mixed up (MOSI, CLK, CSN, MISO), but luckily one can easily change that in Logic Software.
Protocol looks similar to V2x2, but is in fact even more close to MJX V2 (which resides only on my harddisc, as its not working yet).
At least that's the case I did not mix up all things here (man, its late
)
Channel hopping sequence of binding perfectly matches MJX V2:
27 1B 39 28 24 22 2E 36 19 21 29 14 1E 12 2D 18 (27 1B ...)
Just for your reference, my MJX V2 code (not working for me, the arduino version at least sometimes transmits data to my X200, deviation port never binds for me).

Interesting. Maybe we can combine this with MJX if they're close enough.
The trace is also interesting. Durete was right about the data rate change. One of the few initialization differences is 1Mbit data rate. They also changed a few other things:
It wasn't too messy to add to the SymaX protocol as a protocol option. I guessed the channel order as being the same as the -1 version. It was difficult to interpret the button controls, but they all seemed to be independent bits. Increase the channels to 8 in the model setup, then each control you pushed first to last will be on channels 5 through 8. If it works, that is
The trace is also interesting. Durete was right about the data rate change. One of the few initialization differences is 1Mbit data rate. They also changed a few other things:
- The data packet is longer at 16 bytes - perhaps error rate is improved with shorter packets in the -1 version.
- The same tx address is used for bind and data phases. Might cause issues flying multiple X5Cs in the same area. The -1 version assigns the data address.
- The X5C version uses more frequencies. Wouldn't that make it take longer to recover if the rx and tx get out of sync?

Wow guys! 
You impressed me another time
So, my SPI trace capture was ok? If I can make anything to better understand my captures (maybe channel order at the logic Analizer side) feel free to suggest me. Was my first time.
@Hexfet. This evening when I return home from work I will test your DFU. (For me, now is morning )
Thank you guys!

I return with good, and bad news...
The X5C old version Binds with the Devo!
Camera controls works!
Momentary channel 5 active Video record, momentary channel 5 stop video record.
Momentary channel 6 take a photo.
So seems to be channel 7 and 8 are not needed.
And now the bad news...
There is something strange mixing throttle with rudder I can't take off.
As soon I try to take off, the quad try to spin to the left side, like you apply full left rudder
Can't test the other channels because this issue.

Good progress! Maybe I guessed wrong on the trim channels. Try the attached version which leaves those bits alone.
Can you get an SPI capture of changing the trims? All the way in one direction, then the other, then back to center for rudder, pitch, and aileron.
Doesn't the X5C have flip and dual-rate controls? Good news on the camera.
Also need to verify the X11/12/5C-1 version still works

Wow Great!
The strange mixing disappear!
Now the issue is Channel 2 and 4 are interchanged. So when I use the rudder, the quad pitch. When I pitch the quad yaw.
About the dual rates and flips, sorry I forget about it
Yes, the transmitter have shoulder button for flips, and another for change between low and high rates. Maybe I didn't capture this buttons... don't remember.
I can try channels 7 and 8 to these functions when we solve the issue with channels 2 and 4.
About the protocol for X11,X12, and X5C-1, don't worry, continues working without problem with the suboption disabled inside the SymaX protocol.
Good job Hexfet !!!
Do you need any other SPI trace capture? I can capture, but probably not today...
If you need it, I will try to do as soon as possible.
