No mobile network after screen replacement on S7 Edge - Samsung Galaxy S7 Edge Questions and Answers

I replaced the screen of my s7 edge SM-G9350 .. Now I find that no mobile network is working. The sim is recognized when inserted into both slot 1 and 2. I don't even get the emergency call message. I tried to do the default reset but no same problem. Thanks a lot to those who can give me a hand.

did you cut the black pieces above camera and below speakers?? they are for signal
and try to put blue and white wire properly
i cut those balck pieces to show a little board when i make my phone transparent well it looks good but i had to buy the black pieces again from somesones old phone because they are for signals there are total four antenas point
and if didnt cut those peices off try to put wires and pack full phone without glass and screws then see what happen
if you didnt put the whole packing which holds motherboard and antennas signals will not come but your phone will recognized your sim

Thanks again....
Looks a simple, if you have a steady cutting hand !
Done it at last!!
Ordered and recieved a "Ghost Sim Type 'c' " from mobileplace.co.uk (£16 inc p&p).
It fits (just) and switches sims when you "Turn Wireless Off" and then "Turn Wireless On".
Cutting SIMs was just a little too risky for me - I can't cut bread straight! so this this is ideal.
Enjoy.

Sounds good bro! Just ordered one myself. Can you be connected to both lines and networks at the same time- for example can you receive a call from either number at any time?
Unfortunatly not
No, you can only recieve or send on one at a time. But it is a doddle to switch between the two - either soft reset (mmm), or turn phone off then on again, on the signal strenth icon (new ROM on i-Mate calls this 'Flight Mode').
It works for me. One for Work and one for Personal.
Anybody know if this works in the US?
Ian,
how did the dual sim holder fit inside the XDA II. Was it a tight fit ?
Steve
A little, but very managable
Yes, it is a little tight:
o The Sim will not lock but is held in place when the battery is in
o The dual ghost that sits between the battery and cover is a bit of a squeeze, but it is made of some sort of foam, so does work and the cover will lock in place
Mine is fine and has not affected the XDA itself.

what is the difference between the various types? (A, B, C D...)
Do you fold the flat cable (between single sim and dual sim slots) at 90 degrees to get it to fit under the battery?
from what I know the battery sits over the strip and then you loop the cable and sim holder over the side of the battery and it sits on top of the battery.
Steve
Type
I believe the type determines which end or side of the sim the cable comes out of.
This picture should help - sorry about the quality, but you will get the idea.
How did you manage to get the sim in the holder, the large dual sim holder would have to have gone thru the bottom of the hinge of the sim holder on the xda ?
I'm confused.
Steve
Pop it out
If you support the connection to the mother board, the sim holder 'pops' out of its holding lugs very easily. You can then put the sim in from the 'wrong' end and then 'pop' it back.
so can this ghost sim be used with an XDA I then? or is there a different soulution for the XDA I.
Depends on the type of ghost sim used I guess
Sorry, I don't know, but....
I guess it depends how you can get the ghost sim cable to exit the sim card and wrap over the battery.
On the II, to get it to wrap around the battary, then the cable must exit the sim at its base:

If the 'I' has the 'cut off' edge of the sim at the bottom left (when inserted) and the right hand side of the sim is close to the right hand side of the unit, then I cant see why not. Its just a matter of 'fit' rather than technology.

dropped phone, camera not working right.

I dropped my phone and now when I turn the camera on its all blurry and out of focus. The screen is a yellow colour and the photos turn out the same as the screen shows it. Is it possible to fix this myself as its now out of warranty and was wondering if anyone has anything I could try. Thanks.
Take your phone apart and check the connection of the camera the connection is underneath the antenna housing. Be care if you have any more questions see this

This helped me some what. Ive been a repair tech for almost 5 years soo hey. Its always a learning experience.
Hi thanks for the advice and link will give it a try.
well good news bad news. I took it apart and found the camera module was indeed misplaced, so put it back in and put the phone together again. When I turned it back on I got an invalid or missing sim on the screen. tried different sims know to work but still no joy. The camera works now though. Took it apart again to see if I missed something but cant see anything, infact I wasnt even anywhere near the sim holder. Any ideas why the sim reader has stopped working, I must have done something to it.
Does the sim card appear to be at all loose?
if so try bending the edges of the holder in slightly... otherwise, check the contacts are clean on both the sim and the phone..
Cheers
Steve
Sometimes it can be something as simple as its not pushed in all the way. Also like the fella above stated. If your sim card housing is loose it wont make the proper connection. If all else fails pick up some denatured alcohol and a cheap tooth brush. Gentle scrub the contact points. It works wonders.
screen got yellow?
well..first dismantling your phone and then, check the flat-cable that connects the LCD and mainboard, then the camera connection..

The SIM card is missing

my phone broken so i replaced lcd.
Now when I put sim in, it says SIM CARD IS MISSING or it takes forever and is stuck on searching for signal.
Any ideas?
IDEA!!!!
Broken Sim!
anybody?
Can't be a broken sim. Works fine in two other older phones I have. It's what i've been usning. I miss my MDA.
you can disassembly it again
and see if the sin socked pins are solded??? i dont have more ideas... just because of the falling and broken screen
They are. If I shake the phone, sometimes it works. But then I get the searching for signal endless loop..
Well it seems that its screwed up...
but maybe the socket is fine maybe... the anthena is unsolded or the green label for anthena has a little trash or something... but defineltly is hardware issue because the falling problem.
Okay, i tinkered with the phone this morning for the first time in over a week.
My findings:
The back cover where the camera / antenna when the phone fell I guess the clips broke off. It is no longer seated securely on the top (I can wobble it and remove it very easily)
When this moves the phone loses signal.

g1 wont pick up any sim

ok i need some help i bought a beat up g1 to learn to develop apps on but it wont accept any sim card as in i put a sim in but it dosent even reject the card it just dosent change off the no sim inserted screen is there a way i can bypass said screen?
It's beat up.. My guess is the sim card slot thing is broken.
You the development kit comes with a phone emulator right?
Yes it does. So, technically you could use the adb and emulator to replicate your appls functionality. however you should still fix that G1. I'd suggest disassembling the first cover on the back of the phone. u'll need a torx-4 and a torx-6. I got mine at home depot. 10 bucks. also a phillips ph0. once you have it off. On the right side of the phone u should see a thin black cable that is your antenna. make sure its not damaged. most issues with reception happen when someone tried to put the thing back together without porperly securing all the little parts in there electrical tape will work to keep it out of the way when u snap it back together. If that doesnt work u may need a new motherboard. Send me a PM, I have several.

[Q] Mainboard swap - From i9505 to Sch-r970 - Troubles

Hello
I live in italy, a friend of mine took me his i9505 after he dropped it in the wc, i tried to repair it, passed on ultrasonic cleaner, tested the board, but it was clearly fried
Trying to find a cheap solution i found a bid on the bay from the USA for a n ESN clean mainboard, and bought it
It arrived today, found it is a SCH-R970 board, tried to replace it but realized it did not fit into the screen chassis. had to dremel a corner (lower right) for the board to get in properly.
The same for the ribbon cable that comes from the button and the mic/loudspeaker, the connector is slightly dislocated (2mm) towards right.I managed to get it connected in order to test the phone and noticed everything ok but 2 big problems:
The first is that the capacitive buttons (back and menu) do not light up nor work, And second problem is that it i put a sim in it prompts me for the pin, but after i enter it, pops up a "unable to detect your sim card, your device will restart to check for your sim card" and pressing ok restarts the telephone
At boot it shows the "cricket" logo
Do the buttons stay off due to firmware issues?
Is there anything i can do, to get it working here in italy
Thank you
