Just a hunch:Maybe regulator(s) are too hot and 1V8 voltage isn't stable.That affects levelshifting and data isn't coming through?Do you have multimeter?
nvm i found out thats normal...
I flashed to the last one, now i flashed back to the one that supports S3+ which i first used but still a no go.
i checked on loose connectors but it still looks good as far i could see.
its kinda late now im not to sharp.
I saw this in my kernel:

Tue Aug 18 05:57:18 2015 daemon.info sysinit:
Tue Aug 18 05:57:18 2015 daemon.info sysinit: open pic update file fail
Think there is the problem. but i dont know how to solve that
EDIT
This is btw on the first supported for S3+ and on the last version same error

May i suggest this as voltage regulators that provide enough power.

Might be a good idea.But that KIA is rated 15V in,and provides 3V3 2A out.I thought it should be enough.Maybe 12V is too much for it?
Yes and kia regulator HAS to have heatsink,It goes red hot.
Here is my second version for controlling two blades.

I'm gonna wait till you have a cleaner less messy one then buy one if your willing to sell one, i have no skill for putting this stuff to gather from the start but am good at taking one made etc and going from there . or even a really good video on how to im game there ,ill go by what i need with nice walk thu Here is my second version for controlling two blades.

.I'm not gonna sell these.I don't have skills to design proper pcb and I can't source right connectors.And I did this because every now and then,someone is asking around if this is possible to do.I knew it could be done and since no-one else didn't do it,I bought two blades,a controller and did it just for fun and to help other fellow-members.I think there are many members with better capability to create real kits to sell.Ofcourse I'm happy to give my btc-address if someone finds this useful and wants to donate.
Edit: And it wouldn't be that messy at all if I had original S3 cables.But I don't.So I have to be creative

For some reason it doesnt detect my chains anymore after flashing 
What firmware you flashed? Did you reboot?

I don't think I have time or skills open new thread.So I draw schematic with relevant pins and components.All information can be found from interweb also.I just did little changes.Component values aren't so critical,except voltage divider (1k2/1k) should be given values.Those values give exact 1V8 if fed 3V3.And scaling to bigger values could disturb high freqs.Any common npn-transistors should do.And pinout of S1 connector is:
1=Fan pwm
2=Fan speed
3=Rx
4=Gnd
5=Tx
6=Temp scl
7=Temp sda
8=Gnd
S1 control board's power connector pins 1 and 2 are Gnd and 3 and 4 are 3V3 (which you have to feed from KIA regulator).
My picture of schematic is pretty bad quality but I hope you can figure it out.I list here too components which I used.It might be a good idea to add some electric condensators to the circuit.Do whatever you want.And don't try this if you don't know what you are doing.And don't blame me if you blow your controller!

Awesome! Can't believe it actually works
Finaly after a long time my S3+ is alive and running once again.
I still have a prototype version which is kind of a mess.
Coming week ill work on a better version with condensators that are still missing.
Ill post all schemes and with good quality pictures of my pcb when its all done.
Btw, for the L1117 i used a smaller version the bm1117 because my ordered L1117 isnt send yet. But man, that thing runs hot! If someone ever whats to try that u NEED TO COOL IT!

OK, will keep my eyes peeled for your thread ... be sure to post here though just in case.
I think I will make a proper pcb for this and maybe then open a new thread.Now I know how to do it. First I tried level shifting with FETs and nearly throw everything out of the window.FETs I tried maybe had too high gate-source threshold voltage.Using NPN-trannys was much easier.
Problem was (is) in that blade. The other one works just fine.
That's the way to go ..... ! Have you refined your latest "interface" contraption with the S1 controller to your satisfaction and care to detail? Saying that, it may do with it's own thread .....Well done you, very well done indeed!
Problem was (is) in that blade. The other one works just fine.
S3 blade don't have 3V3 line.It's not found at connector so I just thought there is no 3v3 at all.Maybe it's found somewhere but adding external regulator was easy way to try if it works at all.I'm just soldering another board which has no separate Tx,Rx,1V8 or 3V3 solder points.So all soldering will be done to the connector.
Dead chips ..... do a power cycle, as in unplug from the mains then plug back in (even, let it run for a while and they should resurect!)
Didn't help 
. I will try later with another plate which is known good.By the way,I added KIA278R33PI regulator and feed it from hash board 12V. So I don't need 3V3 from cp2102 adapter anymore (and I don't think it could power 2 blades and controller).KIA reg is rated 2A so there's plenty of power.
Hmm ... possibly, as you say, has to do with board condition if the dead chips do not come back to life after running for a while (seeing a power cycle didn't help).
Just wondering why you'd need the regulator though ... can you not power up the S1 controller from the powered board itself (or does it not have a 3.3v line and just 5v and 12v lines)?
