g1 wont pick up any sim - G1 General

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.

My Memory Card wont stay in anymore :'(

Anyone know why ??? It just wont click in anymore... I woke up one day and it was just sticking out - Ive tried jamming it in but its just not reading it!!
Anyone have any problems like this before ? All my stuff os on the card :'(
Only replying so you dont feel alone. But 1st off check if anyone broke inside it, Anything stuck? I could suggest opening it if you have the tools to check it out and maybe fix it if its not latching right.
Also you can still get a adapter at radioshack for the mini sd. I did. It was 20$ came with SD, Mini SD and Micro SD all in one. So least you could get your stuff. =)
Mem Card
Does it work if you hold it in? If so, I didn't like that mine came out occasionally so I hot glued it in. Hold it in, run a small bead of hot glue on top wait a sec and press the glue into place with your thumb. The glue wont run into the phone and it's easy enough to remove when you actually want it out. If your careful you can even heat it a little with a hair dryer to smooth out the glue. Personally, I don't ever take mine out. I had problems with the device not recognizing my files after removal. I install most everything to the SD that works right there.
**Try this at your own risk. I've done it several times and never had a problem. Just don't blame me if you break something.**
You can apply a thin layer of sticking tape around it to keep it firmly in the slot,but make sure you don't cover the connections with it.It'll stick in there and work proper.
Cheers
It just doesnt seem to be reading it at all - But when I plugged in into my wii all the music is still on it and it seems to be working fine.
When I try and jam in my old card it flashing for a second to say would you like to format the card so it must be working kinda... Argh!
Its really annoying - I used it as an mp3 player quite a lot and theres just not enough internal space...
Hopefully it will fix itself soon as that appears to be the only hope
I'm wondering if maybe the mech is loose and pushed inside. May take a little surgery. If I remember right there is some sort of spring loaded mech that keeps pressure on the card connections while in the slot.

Mini-sd slot broke

Today I removed my minisd card and put it back in shortly after, but something went horribly wrong
Somehow I broke the thing that holds the card in position so now it wont stick in.. so I tried to make it stuck in with a paper which works but it doesn't get recognized then, I guess the mechanism which holds the card always turns on a switch thats tells my wizard to start reading the card
Does anyone got any idea to fix it, cause this sux big time (I bought the phone a few months ago for €200), I cant find my receipt but ill try to get a copy of the shop .
Im so pissed right now
Nobody knows, the warranty is overdue
Could I open the phone and maybe fix it myself?
I got the service manual but not the tools, anyone ever seen the inside of the phone, would it even be possible to fix it?
bump ...
similar problem
Hi there
i had a similar problem - had to buy another htc 8125 and unfortunately it came with a broken slot for the minisd card. At first i thought i wasn't pressing the card enough for the thing to click and hold it. Then i realised it was broken. As far as i could see from the little opening there was a white slider which is pushed down by the wider side of the minisd card. It has a spring behind it and somehow it has to click in down position and hold the card.
i tried to push it down with a very very small screwdriver and understand the way it worked. With my bad luck i pushed a little harder and broke that white slider. It just broke in the middle and one part stayed down and the other was pushed up by the spring. It broke exactly at the place where it was pushed by the memory card. So my card was not jumping anymore out - it just stayed in but was not recognised by the phone.
I didn't know what else to do so i found some instructions on how to open the phone and went for it with the hope to reach the memory card slot an hopefully fix it. HTC has taken good care of the stupid slot. It is soldered to the motherboard and nothing much could be done. There are 4 points that hold it but i didn't go that far to unsolder it (didn't know how many springs and other parts would jump out of it). Anyways - what i noticed was the following:
there are two small "plates" at the bottom of the slot. Wheny ou isnert the card they touch and i think this is what makes the slot active and knowing that there is a card in it. I had some dirt betwen them and that was preventing them from making a contact. After i removed that small piece of dirt and inserted the card it worked like a charm. It stays so tight in there now that i hardly can get it out - which is not that bad because i can always use the usb cable to transfer whatever i want.
I think i still have those manuals for opening the phone, so if you decide to go this far and can't find them i can send you an email.
Hope i was of any help
There's no need to open or disassemble the phone to repair the slot,just apply a thin layer of any adhesive tape around it but make sure you do not cover the connectors and insert the card firmly in the slot.
Cheers !
But well even if I push it in it doesnt get detected(I added a piece of paper to hold it in but it didnt detect it still).
I think ill buy a torx screwdriver and open it.
I'll still advise you to check the mini sd in some other phone,if it still doesn't get detected than get a new one or it may need to be reformatted.Opening up the phone might lead onto more problems.
Cheers !

I got a 2gb minisd and a 512mb minisd both dont work so im sure its the phones fault , they have always worked fine.

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
http://xdafiles.100webspace.net/59807.
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..

3g slot failure

Hi there,
I messed up with the 3G slot and now it won't recognize the 3G sim card. This happened when I tried to use a MicroSim without the appropriate adapter (yeah I'm crazy but..anyway). Then the card got stuck inside si I used a knife and some other sharp tools to try to extract it. After 30mn I managed to take out the microsim card but i think i must of damaged the pins because i couldn't see very well inside the slot. As a result, now when I insert my regular 3G card, the tab won't recognize it (Emergency call only, No sim card inserted.....).
Is there any way to open the tab so that i get a clear view inside the slot and eventually see what's broken inside ? Or should I say RIP 3G
Thanks for reading.
There is a guide floating around showing how to open your tab, need to do a search...
What I do remember is there's 2 screws at the bottom of the tab under rubber plugs, either side of the USB Connection slot... These need to be removed then you need to insert a thin blade or something that will go around the side and pop off the back cover without damaging the clips that hold it together...
Other than that I don't know, as I said, there is a guide on XDA somewhere...
Good Luck...

Thanks dude. Sounds scary man .... I'll give it a try
this happened to me too. only i inserted sim other way around and when pulling it out broke one of the pins. I found instructions on how to open tab, bought sim modul and replaced it. you should open the tab if you dont have warranty and see is it broken. +if you dont want to risk oppening it, use flashlight to take a peek inside the slot. you might actualy see what is the problem.

I'll open the damn tab tonight and see what's gonna happen !!! warranty has been voided long time ago anyway.\
Thanks
Here is the guide on what to do and how to open the tab

No sim card error

I have the ATT Galaxy S4 and it's been great, but lately it randomly has No Sim Card Error, and askes me to insert one, the only fix for it is taking out the sim, and putting it back on.
Anyone having this problem?
Can you provide more information about your phone?

How long have you had the phone for?
I read on another forum, back in early May someone with an S4 also getting the No SIM Card error.

Is your phone modified in any way? Root? Customs roms? Etc. Perhaps there's a problem with your sim card. I would start with that.

it is running a custom rom, but it happened with stock touchwiz also, im trying the tape method, hopefully it'll fix it.
Try getting your company to exchange the sim card and if issue still happens just replace the sim tray yourself unless you got an insurance plan that covers free defective hardware or ship it off to samsung for repair.
Here is a link to a sim tray for the s4 that I bought for someone to repair their sim tray.

alright thanks, ill try my tape method first, and if that doesnt work ill do that.
Please insert SIM emergency calls only
I bet I have more experience with this than anyone else with a Samsung Galaxy S4 for AT&T 16 GB
This hand set was run over by a large SUV and I was amazed it survived and kudos to otterbox.
Since then, I've been having this SIM error as well, at random. I see it reported that pulling the SIM out and putting it back in was the only thing that worked, I'm glad simply rebooting works for me, so I don't have to peel apart the otterbox all the time.
I tried the tape and it didn't fix it so I replaced the SIM/SD card tray. The new part on Amazon cost me $14 and the YouTube video showing the operation of peeling these things apart was helpful. I didn't see a video in particular about how they're glued down but I managed to peel the original SIM/SD card tray off, scrape off the adhesive that was still stuck on the motherboard, and install the new SIM/SD card tray.
I still get random SIM errors. No change. Putting a layer of tape on the SIM chip was easy, replacing the tray was difficult, and neither one of these efforts to fix it worked.
My SIM errors are the definition of random, I get one error right after another in just a few minutes, or it will stay lit up and working for hours.
So I put my wife's SIM card in there to make sure it wasn't the SIM itself making the problem. She's never had a problem with her SIM in her Note 2. Guess what, she let me use her SIM in my S4 and it wasn't very long and there it was again. "Please insert a valid SIM" emergency calls only. I gave her back her SIM as soon as I saw the error, as she was not happy about having the cover off the back of her Note 2. I did not get the error when I put my SIM into her Note 2, but was not able to test it for very long, as I got the error on my S4 with her chip so soon.
Next I am going to peel it apart as thoroughly as I can and look for any connector plug that can be unplugged and snapped back in. There was only one little ribbon with a 24 pin connector from the new tray to the motherboard. I'll pull that off again too, and inspect it with a magnifying glass.
I will report if I am able to figure out how to fix this problem.
My wife thinks it's because I flash it, but I doubt returning to stock is even worth the effort. I've never heard of a ROM being the culprit.
more tape
It occurred to me that the tape making the SIM chip thicker seemed to help the problem and less SIM errors.
I will also mention the replacement tray was identical to the one I thought was bad.
I was about to take apart the S4 again when I decided to try lots of tape! I stacked 4 or 5 layers of transparent scotch tape on the back of the SIM chip and it was very snug to slide into the slot.
It was so snug it barely returned from it's "in click"....
I am pleased to report an "up time" of over 16 hours, and that's the longest "up time" achieved since getting run over by a full sized Suburban on Olympic Boulevard.

How many pieces of tape did you use? I have been having the same problem and one piece helped for a little but but it has since occurred a lot more often.
Any fixes?
I guess I dropped my phone one too many times... started getting the no sim error last week. A reboot fixes it temporarily but the error always comes back (sometimes I'm good for 5 hours sometimes its 5 minutes). Tried the tape method without much luck. Went to the AT&T store to swap out my sim... still no worky. Looks like my only options are replace the phone or fix the hardware. I'd rather not send in for warranty repair/replacement as I don't want to lose the ability to run a custom recovery.
Anyone have any personal experience with replacing the sim/micro sd tray or sending in for third party repair? Found this tutorial on youtube. It looks pretty straight forward and the part is fairly cheap (~ $9) but not sure its worth the risk.

Took the plunge and replaced the sim/micro sd tray myself following the tutorial above. It was pretty painless and only took about 20min. Everything is working and no sim error messages over the past day. :good:

I might keep this in mind, but will wait to see if you really fixed it.
I haven't had a sim error in over a week now, and before that it was over a week as we (just that one time in between).
Sony know what made the problem go away but so far so good.

Well crap... insert sim error just came back (probably jinxed myself with my post). Not sure if it's hardware or software but it's definitely not the sim reader itself. May try to revert to stock just to rule out some variables.
Long story short, don't bother wasting your time, money, or taking the risk of replacing the sim tray.

Me too. Happened twice yesterday.
Is there a possible tasker setting that we can make to restart the sim card if it gets disconnected?
possible fix
So guys I found a solution that worked with my phone. It seems that the ribbon connector that connects the Sim and microsd is really temperamental so just push down on it and reboot and signal should come back. As a permanent fix I took a 1/4" piece of foam rubber weather stripping and stuck it to the top of the ribbon cable (where it attaches to the mother board). This kept permenant tension on the connector when I put the plastic back in place.

Not a bad idea but I've never played with tasker. If that doesn't work maybe we could find a sympathetic dev to write a few lines of code. Might even be a way to make the system query the sim card to reestablish the status and clear the error without rebooting?
I'd definitely be willing to throw in a few bucks for a fix but I don't think there are enough people suffering with this issue to put together a bounty and/or get anyone's attention. I did manage to grab a logcat if we can find someone willing to assist.
Just purchases an S4 on the good ol craigslist with this problem. It was unlisted as an actual problem of course, however I am 100% certain that's why it was for sale.
I too get the No sim card inserted message. I took everything apart, testing out a few variables. I have isolated it to the actual ribbon cable as someone mentioned above as well. It seems if I reconnect the ribbon cable and reboot it, the phone will read it until the error comes back. Which happens more often than not. I can't even get the plastic housing on without the error coming back.
- I have tried the tape method as well. On the sim, on the top of the ribbon connector, on the back of inside phone shell.
- I have determined it was the ribbon cable by applying pressure to both the Sim and ribbon locations, both at the same time which is the first time I got the phone to read the Sim. Then isolated each area with pressure and a reboot. The ribbon cable and pin connector seem to be the issue.
Reading over some of the other posts in this thread it appears people have already tried a new sim/sd card piece with no improved results. That makes me want to lean towards this is not the SD/SIM side of the connector but more so on the motherboard side. If it is the motherboard I then I am pretty much at a loss and it is not deemed worth investing another 150$ into the phone for a new motherboard.
Will continue to see if I can do anything to improve this issue. Currently the phone is unusable as I fear for any movement on the device before it disconnects the sim, and I remain on my S3 while I continue to investigate.

So, did it fix it? I took the plunge and replaced my reader as well...but still randomly getting that error. I do have an i337m and running an M919 rom though. Im wondering if it might just be the rom but i have tried two different M919 roms...
