Ok. Since apparently I can't post links of any sort, this is going to get complicated. Sorry in advance. I have links and pictures I could send via Message, if someone would be kind enough to post them. I don't think spamming 10 random posts just to get permission to post links is a good idea...
So I was following Chales Wilkinson's guide to installing a sim card slot. I successfully connected the slot to the PCB, double-checked all the connections, made sure I had not created any accidental short circuits and tried several different sim cards, none of which were recognized. I even soldered the sim card directly to the PCB (without bothering with the slot, thinking it might have been broken), still nothing. I have CM 10.2.1 installed. It had no trouble with the built-in sim card and is otherwise running completely fine.
Searching for things I might have done wrong, I've found that there appears to be a component missing on my PCB. It's the thing that resides above the sd card slot, right next to the screw that fixes the PCB. Now my question is: can anyone tell me, what that was and whether it might be the reason behind the problems I'm having? And whether it can be replaced somehow without getting a new phone? I know that's not likely, but I want to be completely sure before starting all over again...
Sorry again for not being able to show this properly.
@CornholioGSM is a very helpful gent and can guide you through what may have gone wrong.
He could also fix your phone for you, and do the mod 'professionally' if you will (for a fair price, of course).

PM him or he seems to prefer email (see post I linked above).
However, it sounds like you blew one of the teeny tiny resistors around the SIM slot. Seems to happen a lot when people attempt this mod which is NOT easy by any means.

Helloworld.
My symptoms: the device spontanely stopped to detect memory card (the card itself is functioning - checked already, as well as plugging another card into my pola), however the device reacts (wakes up) to the memory card insertion switch status changes (present/absent).
At a glance - all components on the M/B seem to be intact, however I didn't made it yet to unsoldering the card holder and watching inside for bent/absent pins.
Can someone provide me with a clue - what components on the polaris M/B are responsible for communicating with the SD card, and which ones of them I need to check to make sure they function properly?
No clue about that in "classified" service manual from wiki
Am I missing something?
I'm seeing the same thing - curiously problem also occurred on the 6th...
I'd be interested if you find a solution (I'l come back and post if I do)

I'd be interested if you find a solution (I'l come back and post if I do)
So, finally got my hands on that one polaris I noticed lying around.
The problem itself was in card-reader slot. I never found the replacement for the slot itself, so I de-soldered it and soldered a micro-sd card right into place using small pieces of old ATA-166 cable lying around. Turned out not as good-looking, as it could be, done by a professional, but still does the job very well. Now device is functioning properly
However, the connector, that was originally on the M/B got 10 pins on the sides, 8 of which supposed to be connected to the micro-sd card. Maybe some1 here know why the hell there is 10 of them and what are 2 extras supposed to be connected to? Also, is the 8 pin supposed to be connected to the switch that represent card absence/presence?
Just before soldering you should try SD Formatter 2.0 for SD/SDHC (sdcard.org/consumers/formatter/) It almost saved my patience !

I dont believe it is possible... but if you REALLY DID IT... then youre really an incredible INSAN3 Genius!!!
PLease give me further details. Since I opened the Polaris to replace a broken LCD screen the SD card reader broke apart... now I'm using my polaris with the (small) internal memory only (sigh!)
...maybe it's right time for a new phone, but while It is still not broken at all... I would like to try to fix the SD in the way you tell us you did it!
Got me a Gtab today and the micro sd card wont stay in. I push it in all the way, with the contacts to the back of the device and she just keeps popping out. I tried another card and it did the same.
Whats the trick to keep the micro sd card in the slot ?
David
There is no trick - once you insert it all the way in, it should "click" into place. You might actually have a defective device.

Push it further into the slot by a couple of millimeters, below the top of the slot.
Then you will here the "click".
Thanks...that worked! Used something to push it in further than my nail could reach and she stayed in.
Thanks guys
I have the same issue. At first I thought it wasn't being pushed in far enough, but even bottomed out it would not click. I have a friend who had the same problem and his magically worked one time and he hasn't taken it out since.
I found that if I come in at a little bit of an angle I can hear a very quiet snap, then when I take it back out and put it in normally I get the normal click and it stays put. I have repeated this numerous times. It is almost like the internal clip sticks to the side and needs to be convinced to pop back out a bit so the card can actually engage it.
Of course this is all conjecture, I have no clue how the locking mechanism actually works nor can I see in the slot well enough to see if there is something funny going on in there. So my observation is purely touch, feel and sound based. I would be interested if anyone has a different opinion or suggestion as I'm a bit afraid to pop the card for fear it will not go back in the next time.
I've had several GTAB's and never had a problem, but it takes a bit of trial and error to get it just right. The sad part is that they could have moved the mechanism just a bit and allowed the SD to protrude, and it probably would have fixed this problem.
I can't cut my nails, for fear that I won't be able to get the darn thing out.

I used a screwdriver to get mine in. You really have to push it in quite a bit farther than you would think necessary to get it to lock.
One word......toothpick. Does the job nicely, cheap and disposable. Plus, you can walk around looking like Dusty Baker.
Received my tab and everything seems to be going great except when I attempted to insert my Micro SD card. The card never seems to click in and I have tried 3 different cards.
Am I doing something wrong or is this a known malfunction?
The card goes in quite far before it locks.. I needed to use a mechanical pencil point to get it ti seat well.
I just had the same issue, then was able to get it to stay in by having my daughter use the tip of her long fingernail to push it in. It finally clicked & locked. I hope this helps!
Well you have just made me blush, problem solved and boy do I feel stupid.
Thank you, I was about to contact woot which would have put a damper on my day.
So i needed to change the module board of SIM Card, got one on ebay, opened the phone and replaced the little board with 1 flex conector.
but NOW when i turn on the phone theres no message of "sim card not found" and theres circled slash on where suposed to be network.
am i missing something or i might just screwd it up?
Open it up again and make sure everything in connected correctly and that nothing is shorted.
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
ok finally made it.
the thing was that its so damn fragile...o replaced many times the boards in many diferent and sensitive ways...and then one way worked out even though i cannot tell whats the different between the correct position and the other ones that did not recognize the SIM CARD module/board.
Error for me too

I had a similar problem, turned out the replacement tray was bad.
I don't get to say this often but I actually encountered great customer service. I ordered the replacement sim card tray/sdcard holder for a Samsung device on which the sim card reader had been damaged. I received the one piece tray but the sdcard slot was non-functional. I wrote an email pointing out the flaw with no expectations. Got a new part in 2 days. No run around at'all! No 2 hours navigating an automated phone nightmare (Net10/AT&T), just a dang email. I gave em good feedback ratings on their site of course! I don't know if it's allowed but it's so rare to find good folks I feel the need to pimp em.

I just replaced my Sim Card tray. It was working fine.
But for my own safety i re-set the whole phone and re-flashed cm10.1
Phone is working fine. Reading sim, microsd card but sadly i'm stuck on 2g now.

I am in having to replace the sim card holder on my skyrocket but I am having trouble finding out how the sim card holder board is attached to the main board,,could someone direct me to some kind of disassembly guide or something

Here I try to revive a cold dead Galaxy S3 SCH-I535.
This phone is in beautiful shape. The water damage mark is white background with clear red x marks. I put in a fully charged good battery. No response. I plug in the ac power cord, still nothing.
The previous owner said he was trying to reset the phone via Odin (odd, since better to do soft reset from the phone). Then Odin failed and the phone won't power up again. I believe him 90%.
Anything I can do to try to revive it? Otherwise, I may have to replace the mainboard. If I do replace the mainboard, which mainboards can I use? I have a bad Sprint S2 with a bad LCD, but I do not think I can use that since Sprint does not use a SIM slot.
You'll probably want to do this debrick method. Just a couple things, when you plug it into your computer what does it pop up as? If the person did in fact brick the phone via Odin, the linked video requires you to do this in a Linux environment. So you can either boot off a CD or use Linux if you're already set up. Lastly, you need to have a class 10 microsd card that is the exact same size as your phone's internal storage. I haven't done this personally but it's been done Sprint (linked in video) and was brought over to the Verizon GSIII (also linked in video) so it is possible. Best of luck.

The phone is totally dead, no life at all. So I think the mainboard is dead. This is what he said:
I was restoring phones software to sell with Samsung Odin program and it just went blank. I tried to reload software but I can't get it to work
I've seen some videos on replacing the mainboard. I think that is still easier than replacing the LCD. I may have to stick with the same model.

If he used odin and broke it, it isn't totally dead, just means corrupt files in the boards main memory to run the phone. This can be fixed. Totally dead would be more along the lines of dropping your phone in a pool and frying the entire board.
Plug it into the wall with the battery out, if the red light comes on you can fix it two different ways:
1. Video snoop posted, following the exact instructions.
2. Jtag repair, costs around $60.

This is great. After I removed the battery and plugged the wall charger to it, the red light comes on! So it is not totally dead.
Also, after I plugged it into my Win7-64 machine, it shows as "QHSUSB_DLOAD" device. There are some posts about this already on the almost dead Android devices.
I'll do more research and maybe this phone can be revived. I thought it was totally dead since none of the lights turn on.
Thanks the great folks here.
Where to Find emmc dump?
Do you folks know where I can find the "emmc dump" for this phone? So I can use it to debrick my S3? Thanks.

Got it.
I gave it a first try and it did not work. Part of the reason is that I could not follow the direction 100%.
I used a Sandisk 32GB microUSB. I may need a 16GB drive. Also, the card does not say it is class 10.
Then my old card is crappy and I could not use it. So I used a GE camera and used the camera as a card reader. I have no problem getting the SD card recognized under ubuntu.
I copied the the disk image to the SD drive as directed. It sees 23 partitions. However, when I put in the SD card in my desktop, I only see one partition, which is about 64MB. I do not know if this is normal.
I'll try to get a class 10 16GB and a good card reader to go with it.

You definitely need the specific class 10 sd card that matches your internal memory and follow the directions exactly. You'll get it though, sounds like you're persistent enough.
The idea behind it is tricking your phone into thinking that card is your internal memory, it won't work without the size being the same.

I'll keep it trying to see how it goes. Thx for the help.
I do not know if the debrick.img method really works. I've watched the video from this Verizon forum, but he never showed the phone, not the computer screen, but just talking. I've heard some other folks (Sprint, etc.,) get it work. But I just do not know....
I've got a new card reader and a Class 10 16GB micro SD card. I followed the procedure precisely. But the phone is still cold, 95% dead. When I mounted the SD card under Linux, it complains about the corrupt GPT table. I ran "parted" command (as directed), but the command blew up and never completed. Many other folks did not even mention parted command.
I'm puzzled..... Does it really work?

Hi
Follow the instructions in this video exactly, http://www.youtube.com/watch?v=dU5H8NJ7vTM&hd=1
chances are you can repair yourself. Here is OP http://forum.xda-developers.com/show....php?t=2504066
Good luck
I watched that video and followed the steps exactly. But it is still no-go.
Also, in that video, the OP never showed any phone, or any of his work. He only claimed in the forum that his phone vibrated. I sent him PM twice, but never any response. It appears the OP is into iPhone more recently.
I also PM'ed other two folks who claimed this worked, at other forums here. But again, never any response. So I do not know if this method really works.
If anyone can get it work, I'd be happy to send my MB to him/her and pay the postage.
Just made the mistake of flashing the firmware for a Sprint SGS3 to my Verizon SGS3 (not modem, just sbl, rpm and tz). I'm hoping this YouTube tutorial will fix my situation.
Anyone know if there's a way to manually push those files to the SGS3? The device is completely dead, except the red light does come on when plugging into the wall without the battery.

This is exactly what is happening with my I535. I was never able to boot the phone with the SD card. Some folks claim this procedure works, but I've never been able to get anyone to confirm with me. I believe some of them just have soft bricked phone.
I've pretty much given up on it. Swapping mainboard is not that expensive....
