Gear S2

Attached is my Pinout for simple USB cable.
In theory also for SM-R720.

With SM-R732 I have successfully tested.

But during my Soldering Adventure... I have killed/lost 1 little tiny SMD chip...
Now my WiFi BT range decreased...

According to SM-R732-TSHOO-7.pdf I have lost:
Code:
C108
Please, I need this document:
Code:
SM-R732-EPLIS-11.pdf
Or please help me, what is:
Code:
C108
L105


So I have chance to find maybe sparepart...

Thanx in advance.

Best Regards

Please I need help.


Maybe Rear Case of SM-R765 is compatible with SM-R760 and contain Flex cable... look at Pics from FCC.

Maybe then no POGO Jig nor Soldering mandatory...

I can not find correct part number WITH Flex cable...



Code:
            Rear Case
SM-R760            GH82-12922A
SM-R770            GH82-12954A
SM-R765            ???
Maybe somebody can share please Service Manual from SM-R730 and/or SM-R765... to learn more about external Connector.

Thanx in advance.

Best Regards

hey adfree...
bro i was wondering if you could possibly help me fix my gear s2 classic...
i just bought it tonight.. for me that is Oct. 30th 2017
i bought it for $50CAD in needing repair condition, when it boots, it boots to a snowy screen and does nothing, i cant get into wireless download mode, i cant get into recovery, i cant boot normally, but i can get into download mode...
BUT>>>> out of the 5 gold plates on the board for the usb connection...
one of them was broken off the board, and it just so happens to be the GREEN usb communication line, the 5v positive line is good, the ground is good, and the white usb comms line is good...
just that killer 4th one broken off... i dont have a magnifier to even begin to attempt a needle point connection, but was hoping maybe you might know of some alt. test points for usb comms??
i found a alt. point for the usb 5v red lead, and the ground,
but have not been able to locate usb alt points
again, this is a gear S2 Classic...
sorry if hijacked, please move accordingly if so.. thanks in advance and i hope i can get my watch booting

Hello.

I think I saw your post on XDA...
I have tried to answer.

As I have written in XDA.


Checklist.
A.
In Download Mode very usefull infos visible.

Model name aka Product name in red lettern:
SM-R732 or SM-R732X visible?

R/L on or off? This Reactivation Lock...

Also the other infos are very usefull.

Easiest is to make Photo.

B.
If you need Combination Firmware, PM me...

Best Regards

Btw.

I have killed few weeks ago my "white pad"... Data -

On my test SM-R732...

Ripped off with soldered wire during some movement...

I have not checked with microscope or other Tools if I am able to solder something again...

I was so frustrated and have desoldered the other wires...

But you give me hope.
To check it maybe in few weeks again.

Best Regards
