SIM issues - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Ok its been few months, I have been on skyics 2.3.5 for a while, can't use ICS yet.
I started getting sim has been removed, I reboot and its fine, not sure why this is happening, I had it unlocked about a month a go and use in europe with out issue with ekit SIM. Came back and for a week it was fine, now this started and its very annoying any one seen this?
Last time I had an issue it was hardware and had to replace phone. Now I don't want to replace phone and advice? Before I start changing the ROM etc?

what was the hardware problem before ?

Had to replace phone. Not 100% sure what was wrong exactly but ATT replaced phone.
Can this be traced back to ROM or radio some how? Or maybe my SIM?

1st troubleshooting step ----------> replace SIM and see if it would fix the issue ..

Thanks for the reply, any other suggestions?

You can cross-check your SIM's function in another similar/unlocked phone. Also maybe try flashing a different modem.

Well that's the thing, the sim works here afyer reboot. Good call on radio flashing diffrent one now.
Im starting to think that changing SIMs might work as thia usually happenes when the phone is in my pocket. Lets see how flashing radio goes. Maybe I need to move to a new ROM, when is official ICS out?

Ok after reflashing radio and clearing cache etc.. it did it again.
Just walked out of ATT store with new SIM lets see how it is.

At this point, I'm guessing SIM will clear it?... Android 4.0.x fourth leak just dropped from Samsung. Official ICS for SR is (unofficially) overdue.

[Q] help i dont know if my phone bricked?

I bought a g2x from craigslist. its brand new but i guess that previous owner has done some update or something now it does not show any baseband version. So my Sim card which i changed to 4g version yesterday does not show any network. my old sim card did not show any network either.
this is what i see when i look at About Phone
Model # LG-P999
Android Version 2.2.2
Baseband Version : Unknown
Kernel Version : 2.6.32.9
Build Number : FRG83G
Software Version : LG-P999-V10f
I am coming from a vibrant with using bionix and not new to rooting or flashing rom. I did research a lot. But not sure if this is something that can be fix.
Please help.
thanks a lot in advance
Try the official update ota or via LG, other threads describe the process and that might get you the new baseband.

I tried to run the software update check from the phone. i connected with wifi. but i guess as it does not have a connection with tmobile netowrk its showing connection failed.
I think what heysharon is saying, is to update through lg website with your phone connected to your pc.

Ohhh, Yeah tried that already. But LG updater says device not supported for update. is there a way to flash the baseband ? I have a feeling that the previous owner flashed a o2x rom or something which changed the baseband. and then he ran the recovery to fix it.
Which model do you have? Check under the battery hood if it's Model 990 or 999. Perhaps it's wrong update for the phone.
Sorry I saw now you said it's 999. If there is no baseband you might have to return it to the Tmo...

Was it working when you bought it from the Craigslist seller? Did you try it with a SIM card before you bought it? Just wondering if the problem was there when you bought it or if you might've done something to the phone after you bought it.

it was working with his sim. my sim did not support 4g network at that moment so could not check it with my sim. then i got my sim yesterday. and have been trying to use it after words. no Luck. i guess i just lost $300.

That seems odd. You saw it working with his SIM? Did you or him make any changes to the phone software after you saw it working? The baseband wouldnt just disappear.

Probably didn't flash an O2X rom as that would've changed the partition table and I don't think you can restore the G2X system back to it ... well at least without going to great lengths to fix the partitions.

i guess what happened is i really did not check it throughly. his sim was inside the phone and when he gave me he took it off and did a factory reset. thats what it was. and i was texting him before we met and he was calling me or texting me from his phone. i believed him. and i can see what happned for believing him. great
Try doing the regular nvflash thing root it n flash a rom or stock nanroid maybe that'll bring the baseband back

that isn't changing your radio band, so i'm guessing that you didn't try it. it's a pretty stupid idea, but who cares as long as it works, right? dial *#*#4636#*#* and click on phone information. then push menu, select radio band, and choose USA. otherwise, take it into sprint lol
This happened to me today. Flash to a stock rom (if you aren't already) and update your profile and PRL. Did the trick for me.
Good luck

[Q] Help!

hey guys i just recently bought and unlocked my skyrocket...the phone has been working great for a couple weeks now the battery randomly shuts off and i get a black screen with a vibrate when trying to boot phone up. I installed the Juggernaut ROM onto this phone and it works like a charm. I even bought a new battery and it worked for a day and now back to square 1. I even tried my battery from SGS 4G and that started the phone. What exactly is wrong? Rom or battery?

I don't even remember what juggz looks like. It's a year old gb Rom. Try an ics Rom if you want stability and a newer os. Sky-ics, mohans embryo, to name a couple.

Are the battery contacts all dirty, bent, or something look wrong with them?
Restoring to stock makes no change meaning that the problem is with the phone itself or something. Maybe you had messed it up by doing something wrong while flashing or... ))
I think what better for you is that you should contact your carrier and have them replace your phone. This will not be a problem as you've just got it.
Just tell them exactly what happens to the phone, but don't tell them that the phone used to be rooted.
When you got your replacement, pm me inbox, I'm gonna show you how to install CMW, and then go straight ahead to Jelly Bean which is the ROM I'm running right now. Since you said your phone was unlocked, I think even if you use your stock ROM, you still are able to use T-Mobile SIM card or any others. ( But I was told by an ATT agent that the phone needed to be used at least 3 months or something in order to get the code to unlock it)
The reason I'm using custom ROMs is that I can do a wifi tether whenever I want, and be able to run the most recent Android version as soon as it is released.

[Q] Searching for Service

I haven't found any answers on this, but once or twice per day my phone will be stuck on Searching for Service even though in the status bar, it shows like 3 bars of 3G or 4G. Data still seems to work, but this seriously drains the battery. I'm on stock unrooted HD. Any advice is appreciated. I already tried a new SIM. I bought this phone here on xda, no box, so I doubt Verizon would let me exchange it.
I know this is a silly question but what radio is installed?

VRLG7 is a downgrade in release but does not hurt to reflash any of the modems to see if it fixes problem and which works better for your area. Affects 3G more than it does 4G..

Maybe root it and try a custom kernel, though I'm not positive that will help. Possibly a total wipe and reinstall of a stock system? If you bought it from someone here on xda, chances are it has seen some mods. Hopefully someone with more knowledge on the subject will chime in for ya. I just hope you didnt buy someone else's problem... :-\

I got it and it had never been rooted before. I rooted it, used custom ROMs, they all weren't my cup of tea, so I unrooted and flashed the stock HD images via ODIN yesterday. I just flashed the HE radio, and it seems to at least be a bit better. I'll keep experimenting.
It's still dropping signal. Sounds like I'll be calling up Verizon tonight.

What portion of the "hack" affects the reception

Rooting, ROMS, Kernels, Basebands, MODs, So many flashing options. I lost my reception at my cottage which is on an extended network roaming. As soon as I go into that area everything drops, voice and data. I Odined back to Stock unrooted did a factory reset and the service returned flawlessly.
I was on latest baseband J1 at the time, SynergyROM, MIEA backed up, bootloader unlocked.
Now I'm getting itchy fingers again. Want to go back to Synergy, etc. But I DON'T want to loose my reception while I'm at the cottage for a few days. It's my only connection to the world.
Starting from scratch again, what could've been the culprit?

Baseband updates certainly do affect signal. It seems that the stock one works best for you.
The good news is you don't need to update baseband to go to a different ROM. You can keep your stock radio and flash a new jellybean leak without altering your signal.

I've also noticed that many ROMs have roaming disabled by default. Not sure if it makes a difference, but might help.
