So I just got an LDU of the S6 and was wondering if I dump in a new OEM S6 Mobo am I going to have any problems or will I have a fully functioning phone. I know supposedly that the LDU are missing certain things antennae leads and sim access, and imei #. But are these all fixed with a logic board swap or will I have problems? Anyone know
Well I did it since none of you know. I switched the ldu Mobo with an at&t Mobo and a Verizon Mobo, and on both the LEDs and buttons would light up but the screen remained blank. So swapping just the Mobo won't turn an ldu into a usable cellular S6. Don't know if this is going to be possible. These ldus maybe a lost cause as phones.

My Skyrocket has always been plagued by GPS problems. I've tried every single fix in the book - reflashing, the GPS fix, taking it out of the case, etc. Nothing's really worked. I'm sitting not 5 feet from a window and my mother's SR can get a GPS lock within seconds, whereas mine sits in the window for 20 minutes and can barely keep a lock.
At this point, I'm beginning to think it's an antenna issue.
Has anyone disassembled their Skyrocket and found the GPS antenna? Is it on the inside of the back half of the bezel?
Also, I have reason to believe my NFC is also broken. After having repaired it software-side (something caused CM10 to spit it back out and not load the NFC apk), Android Beam still doesn't work between my Skyrocket and my mother's. It never has (whereas the software is properly configured), leading me to believe one of the phones has a bad NFC antenna. (EDIT: Mom's phone appears to have a bad internal antenna connection. Oh well!)
Does anyone know where the NFC chip/antenna wire between the chip and the antenna are?
This is an annoying issue. I've had something like it happen to me. The GPS in my i727r only works with Rogers roms and AT&T JB rom. AOSP & AT&T roms take 20 minutes or more to get a lock and a bad one at that (1600 meters). NFC is fine though. The NFC antenna is in the battery, it should look like this http://tinyurl.com/dxc8anl . Further, (A) Android Beam & (S) S Beam are not compatible. Use only one, (A) or (S) on both devices.
The GPS antenna is on the rear plastic, the one that's under the battery and over all of the backside of the phone, the one you see when you remove the battery door. Don't remember the exact location, I think it's on the upper side. You might need to remove it (5 or 6 screws and pryer), clean the antenna contacts both on the cover and on the board, bend the board contacts outwards, and assemble it.
NFC - if one of you has fake battery, NFC won't work.
Both phones are using stock batteries. They do have the NFC antennas (you can see the ridges through the label). We are in fact trying to use Android Beam.
I'm not looking for the part of the antenna that's on the battery - I'm looking for where the chip is to see if there's any obvious board damage to the antenna wire between the chip and the antenna coil. Both phones have 2 batteries, and trying with any battery combination doesn't work.
I ended up getting an NFC tag and checking it with both phones. Mine works, my mother's doesn't. She doesn't care about NFC, so that whole issue is pretty much resolved.
However, that still leaves the issue of the GPS antenna. If I open the phone, am I going to have to break a warranty sticker or something similar? (not a HUGE issue, but I want to make sure my AmEx extended warranty is gone before I do that)
Hi
I recently did a rebuild on my one s to replace the vibrate motor/ribbon cable & also inadvertently resolved my touch buttons not working
Since then unless the phone is in a very strong signal area (we have a femto cell in the office which it connects to fine) it gets nothing at all - my sim works without issue in other phones so that's not it
I understand that the GSM antenna is in the lower section of the phone, I've checked all the gold contacts and the wire running down from the mainboard to this daughterboard, disassembled and rebuilt etc but the issue persists.
My question is, is it worth going through the radios and flashing to see if thats it - or could it be the replacement part was faulty?
Any advice or things to try would be appreciated
Cheers
Have an sgh I747 att galaxy 3,
My issue and question, i have had this phone for a while it has seen a LOT of abuse, have replaced busted screen 2 times!
with that in mind latest issue and yes did factory reset and have 4.3., camera shows nothing on screen and says a error, also wifi will not turn on at all slide to turn never connects goes to off position, ni assume due to many drops the board had said enuff, !
now my question if i buy a new logic board / mother board will i have issues connecting to my provider? AT&T, imei # and so forth, or will popping in my sim negate that issue?

Hi
I have a rooted Galaxy note 5 phone SM-N920C model.
Some water got into my phone and i had to take it to a phone shop to get it fixed its was working fine after the water damage but the power button had to be pressed hard to work.
the repair guy told me he had to replace several some parts i think some cpus.
After i got my phone my sim would work and then randomly stop working and i couldn't make calls nor will mobile data work. Then randomly it would work again and stop randomly.
i tried my sim in another phone and it was working fine, even tried my friend's in my phone and it had the same problem.
An important thing that i found is that the model in my device info has changed from SM-N920C to SM-G935T Aka Samasung S7 Edge.
after a couple of days i figured out that outside the house the mobile network works fine but inside it it doesn't might have to do with the signal i'm getting from the device. So im thinking of this an error from the guy who fixed it so i'm going to return it to him.
Things i did trying to fix it : flash all kind of different roms, unrooted, rerooted and also tried to install S7 Edge roms also tried the S7 Edge stock rom.
Thank you for reading ,

Hey everyone,
I've looked around the forums quite a bit and have found some similar problems but have not yet found a solution to my scenario.
Basically, my S6 Edge received minor water damage, enough to cause corrosion onto the motherboard through the volume and power buttons.
The phone was inoperable for about 12 months (I was travelling and didn't have the funds to repair it), I've since returned home and decided to fix it.
I took the phone apart, cleaned the corrosion and put the phone back together, I believe the hardware is fully functioning now, everything still works.
Once I turned the phone on it wouldn't pick up a network signal. I went into the 'about' section and found that the phone has no IMEI or Baseband version and it won't recognize a SIM card.
I've rooted the phone, it was originally running 6.0, it's now 7.0 through a manual installation with Odin3 and a factory reset, still no IMEI or Baseband Version.
Everywhere I've read on the internet say I need to backup/restore the EFS files, but that's not the case because they seem to have vanished from thin air.
Other information:
Phone was originally locked to Virgin Aus, I had it unlocked and used it with a Canadian pre-paid SIM no problems
The IMEI is written on the back of the phone
Model is Samsung G925I.
If anyone is able to offer any insight into this I'd be so grateful! I couldn't see anywhere, but can I load a generic EFS file onto the phone and manually enter my IMEI number?
Thanks!
