Hi,
I've had my Galaxy S for ~ a year now and have never had a problem with signal problems. I bought a second Galaxy S for my wife, and it gets a very weak signal. I've tried switching the sim cards, but have the same issue - the new one has low signal, my older one has full bars.
They are both running cyanogenmod nightlies (ver. 9)
The only difference I see is baseband. The one with full bars is running I9000XJVK the one with weak strength is I9000XXJVT.
Is this the problem? Can I change the newer phone to I9000XXJVK?
Hey man this is what you are looking for. Grab the jvk zip from here and flash it in cwm that will change your baseband to the same as your phone. Baseband is your modem. Build is the firmware that phone is running. This will fix it guaranteed.

Thanks - just flashed it, the modems are the same now. I still seem to have the same problem though. Wifi works fine, by my signal strength sucks.
Any other thoughts? I'm lost here.
Hopefully it's not a hardware problem..
Where do you live? For example. I live in Canada so I use the Ugkg3. Modem. Btw the wifi connection is not effected by the modem.

I live in Ottawa.
One of the sim cards is 7-eleven (Rogers) the other is PCTelecom (bell)
They both get full strength on one of the phones, and only 1 bar if anything on the other.
Try the Ugkg3 modem its in the same thread.

I've tried installing:
JVK
JL2
KC1
KG3
nothing
Hmmm kg3 is the north American modem. I think jvk is for Europe. If it still doesn't improve I would guess hardware. Was it always this bad? Did you buy your phone with cm9?

I don't know if it was always this bad, I bought it used and then installed CM9 on it.
Guess I'll keep playing with it and see what I can figure out.
Maybe flash it back to gingerbread, wipe it and reformat the internal sd. I'd use the kg3 modem though. Have you used odin before?

I've used Odin before. I can try to flash it back.
I was looking at the back of the two phones - beside the sim card there is something that looks like a sticker, it looks like this has been pulled off on the one that doesn't work as well. Could this be the issue? Based on what I've found, the antenna is around that area...
Seems like hardware, but I would flash it back to stock gingerbread. There is a thread in general with all the stock roms and odin and pit files. Grab the odin download with pit files. Use 512 pit. Grab the Ugkg3 download under north America in that thread its 2.3.3. But let's just see if it fixes it. Before doing the flash I would go into cwm and wipe cache, dalvik cache and factory reset. Also reformat internal sd under settings. The only way to completely eliminate a software problem is to make your phone bone stock.

Ok, doing it now. Fingers crossed.
If it is a hardware issue, am I screwed? or is there anything I can do to try to fix it?
If it's hardware then you would need to take it for repair. You would think if it were hardware then there would be no signal at all.
Sent from my GT-I9000 using xda premium
No dice. Weak or no signal.
I'll do some reading up on hardware issues. I only paid $65 for the phone, so I guess it's not the worst thing that could happen, but still annoying.
Bummer. Gl man.

Yup. I've taped a small piece of wire into the socket and I'm up to 3 bars.
I'll have to find someone to do a more permanent job
Sigh.
Now to root again. What's the easiest way? I think I used an old method last time.
Every time I Flash A rom I cant connect to any network, I have no signal, nothing. Can some explain to me why this is happening? It just recently started happening. Ive flashed back to stock multiple times and I DO have signal with stock. But when I flash a rom, I lose signal. There is nothing under APN list

Flash a modem. Jk4 is kind of a standard one for I9000 roms. Look in the modem thread. Also, cm/ics roms use a different install script as regular (stock base) roms. Be sure to get the right one,k or it still won't work.

Ive flashed a modem it doesnt help, When I go into phone info mostly everything is either N/A Or unknown. I flashed back to stock. I have never ran into this before. I dont know whats causing my phone to do this. I started 2 days ago when my phone randomly started rebooting. So I flashed back to stock(With bl) and now whenever flash a rom everything is unknown.
Whats the standard SGH-i897 modem?
Also this started happening after I started using Devil kernel inside my own roms.
I've had this exact issue before, right after I flashed GB bootloaders I flashed them again and it worked.
On a side note, are you restoring a nandroid?

Sent from my SAMSUNG-SGH-I777 using xda premium
Are you flashing the right type of modem? Aosp (cm, MIUI,ics) uses a different install script in the zip. It installs to a different place. Samsung based roms can actually use Odin to flash them, if you make a tar.md5 file for it. If you use the wrong type of install script, it won't work.

I flashed the I897UCKF1 from that post. Ive flashed my OWN rom, which means I control the modem, It just started doing this, and I am stuck on Stock until I figure out whats doing this. Ive tried multiple modems, Nothing gets and APN or Network operators on either list.
Try starting from the kk4...then flash kk4 corn kernel to get cwm then go from there.
Worth a try.

Hi guys, finally decided to put down my sensation and move onto the Galaxy S III. I'll miss it =[
So I've bought a UK Galaxy S III I9305 from T-Mobile.
I've managed to root and that and it everything was working fine so I thought I'd flash some ROMs and see what one I like. I flashed two of them (Pandoriam and rXTREME). They worked fine except mobile data would not work on either of them. I followed some instructions in the thread which said to turn on GSM only, restart then switch back to WCDMA. But it still wouldn't work. I flashed different radios as well (or modems as they're called for samsungs) and that didn't help either.
I've just flashed a stock 3.1.2 EE firmware and the device is back to complete functionality and the 3G came on immediately. I also noticed when I booted the phone the first thing that popped up was a box asking if I wanted to enable data connections; this never happened on the custom ROMs. I figured it must be me or my device since it didn't work on both ROMs, hence my posting here instead of their threads. Am I doing something wrong here?
Any help appreciated. Cheers.
Did you check the apn settings? When I flashed those roms I had to re enter the settings again

Ah this wasn't suggested. If you can be bothered could you possibly outline what I need to do. I know how to get to APN settings, do I just note down what they are now on a stock ROM and set them the same way on a custom ROM?

Ta much mate
Ok, my tablet was an sgh-i957 (lte at&t version), but it was bricked, so i bought a jtag service on ebay, and after i receive the tablet, the boot loader was of the p7320 model, so i flash the tablet with the sgh-i987 stock rom, but after flash, the memory intern memory was just 127 mb (it was the only problem, the other things was working good, even the 3g and 4g), so i re-flashed the tablet with a stock ICS rom, from Norway(Telenor). All was working good, but..Now i have another problem, my 3g is not working (just edge), the stock rom that i use is from Norway (telenor), and the bands that they use for the 3g are 900/2100MHz, but i need the 850 / 1900 bands to make it work in at&t, how can i solve this?, can i flash another modem to back to the 850 / 1900, or make it quad band.
My actual rom is ICS from Norway(telenor), and the baseband is P7320XXLPI
IM GOING TO DONATE TROUGH PAYPAL IF SOMEONE SOLVE THE PROBLEM.
Thanks..
You can flash another radio thru your recovery. It would be a zip file. The problem is finding one. I've tried to search for one but don't see any. I'm also not sure how close the 7320 is to the 7300/7310. You most likely will not brick your device flashing a radio. You run a high risk flashing a kernel or rom. so you might try some for a different device. Just be prepared to odin back to stock. You might even try a radio for the i727, galaxy skyrocket. I successfully did that on my i957. I flashed ucmc1
Edit. If you go to the i727 development forum, go to the stickies there and look for vincom and his rom, radios,etc. There are a bunch to choose from.
Ps, I would recommend the ucli3 skyrocket radio. The i727 and i957 have the same modem chip.
Fyi, this is the radio I flashed on my i957, it's from the i727, http://d-h.st/NWW. It'll work on ics. Don't need to do any wipes, just flash over what you have on your tab now. Particularly don't wipe system!

If i restore by odin with a stock firmware, the modem can be restored too?
Yes. Odin will put the stock firmware and radio back on. I'm pretty sure the i727 radio will work. It definitely does with i957 firmware. Just not sure with the 7320firmware you have. But its more hardware related than firmware and you have the right hardware.

The first step will be to put a custom recovery on your tab. This file is twrp, http://d-h.st/fqw. Download it on to your computer. You'll flash it with odin. You install it just like the stock rom ie, run it in PDA with only auto-reboot and f.reset checked.
Note, this twrp file its for the i957. I'm not sure what it will do with your 7320. Partitions may have been changed and you may run into the same problems you did when flashing the i957 rom.
Edit: I was able to find cwm recovery for the 7320, http://d-h.st/Wcv. This might work better.

Any time you flash something there is a risk of brick. But recovery does not mess with the partition tables. I think worst case it didn't install and you might have to odin the stock rom

Can you get into recovery? Next step is to download a radio onto the tab. Put it were you'll know where to find it. You'll boot into recovery and then choose that file to install. Don't do any wipes, just install/flash it. Reboot and then check your baseband. Should be good to go from there
Which recovery did you end up installing? Cwm or twrp?

I clean flashed it and in TWRP it said done and I clicked reboot and it was rebooting for at least 20 minutes...not a bootloop...just the boot animation playing over and over and over. I tried force rebooting and my SIM wouldn't be detected so I reflashed it (again, clean flash) it and now I'm waiting on the boot screen for an hour+...I know first boots usually take longer because it has to setup the OS...but an hour..? Did I do something wrong? Anyone know why this might be happening?
EDIT: I got into the ROM. No cell signal though. Anyone possibly know why?
Might have a bad download. I know u did a back up of your previous ROM? U should re download the ROM again make sure u select the correct variant and see what happens then.

Considering his post is from June, I hope so. You may want to post your full issue here or in a new thread or the G3 thread itself.
Well since this thread is here, I want to ask some questions about CloudyG3's rom on the Verizon variant. Basically how it is? I really like the stock experience of the G2.
I've used the Flex port with good success before but there were several issues that I came back to stock. I know the stock SMS app refuses to work, which kinda sucks. I really like the popup SMS/MMS feature.
I'm just looking into whether it is worth it before I take the plunge. What are the steps to making CloudyG3 work the best?
1: What SMS is a good replacement that is similar to stock?
2: How to get the radio working?
3: Knock Code won't work, correct?
4: What issues/bugs to expect?
5: ????
