Hi.
I have two I9000Ms, flashed JPJPG and tested them working ok in Canada. Went to visit in the middle east. Then I encountered an issue: One of the SGSs has amazing/full reception, the other one has completely no or extremely little reception. I'm using exact same sims. I even tried switching sims but still yield same result. I'm thinking i should install the proper modem or re-install the JPJPG modem by itself.
I would highly appreciate some advice. I can't seem to find any info since this maybe a specific issue.
Anyone? I can safely say that im desperate for some direction.

Hey Guys,
I have a GT-i9000 (Unlocked) and after a few firmware upgrades I have been noticing worse call receptions (more drops) and worse 3G data performance.
For example, I once had near perfect reception and few call drops along my drive home, now (5 firmwares later) I have been dropping calls like my old iPhone (actually worse) and what is more upsetting, yesterday my friends with their iPhones all had signal while I was getting the no service icon.
While i know the Captivate users can use the i9000 kernels (but swapping out the modem file) I wonder if anyone knows if I can use their Captivate modem file (JG8) instead of the one that comes with JM7 to fix my issues with reception and 3g performance .
What functionality will i lose? I travel to Germany often, will that cause issues with 1900Mhz and 2100Mhz bands ?
Is there any other reason that my signal would be so poor?? I really need help with this.....
Is anyone else using an unlocked i9000 on AT&T and having poor voice calls (signal/drops)?
What firmware are you using now? I would like to see if this relates to my issue.
I'm using JPC on my Bell i9000m and am starting to wonder if the reception is not as good as with JH2... I am contemplating using the JH2 modem file with JPC to see if it helps...
Coincidentally, I'll be in the US in a few weeks so I want to ensure I have good reception on AT&T as well.
i am using JM6
Just tried the modem from the the Captivate JG8, it would not even install.
So I am running JM7 now.
I will see how many dropped calls i get today.
JPC stopped booting for me and I am on JM7 as well - I'll post my comparative results as well tomorrow.

Just did some tests with my wife's iPhone (3gs) and my galaxy s.
Passing the same dead zone and her phone could make calls and mine would fail.
I wonder if i put it on gsm mode only if that would help.

I'm having a problem. I have a GT-I9000M device that shipped with the latest Eclair ROM (JH2) for that model. Worked fine of course.
A few days after rooting it I flashed JPK and then applied Doc's Mod. It changed the boot screen and product name in About Phone to GT-I9000 instead of GT-I9000M. I wasn't too worried, though, because I was sure that with the speeds and reception I was getting, that I was getting all the bands I was suppossed to.
Then I decided to flash JM8. I followed the instructions to do so, then applied Doc's Mod. The ROM was great but I was getting almost no reception (either 1 bar of "G" or zero bars "H" in most situations). Super slow/poor data and phone performance.
Then I decided to go back to the stock JH2 that the phone came with to get my speeds back. I flashed (using 512Pit) the PDA, Modem, and CSC for the device. Booted up and ran great, and both boot screen and About Phone have changed back to GT-I9000M. But while I'm getting some "H" reception, reception over all has been quite poor and not what I got originally with the device (or so it seems).
How can I check to see what bands I'm actively getting and which I'm not? What steps should I take to resolve this? Thanks in advance!
Grab the SGS Tools from the market. It has some secret codes that will answer your question.
After testing, my Galaxy S is definietly only getting minimal 1900 3G coverage everywhere despite my other phones pulling down very strong 850. So something is definitely wrong it sems, how would I go about fixing it?

Follow my instructions here.
you need to install BMC product code, right now i bet your product code is KOR, i was having same problem only getting 1900 band, after flash back to JH2 change my product/sale code to BMC, then wcdma 850 will work again
Once I flashed back to UGJG8 I was able to change the product code which fixed it right away (that didn't work from JH2). After fixing, I flashed back JH2 again and it continued to work fine. I then flashed JPK and it continued to work fine. Although if I want to downgrade from JPK, I now know that I need to go to UGJG8 first. Thanks for all the help!
Um, hi.
Last night I purchased a new Galaxy S Vibrant from Bell. Of course the first thing I did was jump over here to XDA to do some required reading. I proceeded to unlock, root, and flash froyo. All was working fine, until I found an App on the ROM to do a factory reset. There was still a lot of bloatware on the phone so I figured that would be a good idea. After that, I've begun experiencing low signal issues in certain places. The phone can still connect to the Rogers Network, and I have the correct APN settings (I get 3G), but in many areas my phone loses signal. Before the data wipe I could make calls just fine out of my basement but now I don't get signal down there. Is there any way to fix it? I know this sounds pretty vague, however if you need any more information I'll be happy to provide it.
Cheers!
(By the way, I love this phone!)
A lot of people have complained about losing the 850mhz frequency when upgrading to froyo on the bell sgs, so if you can't get 3g then you just lose reception all together, there is a fix for it, I believe its in the android development section, search in there, I saw it in there yesterday, search 850mhz lost signal and it will come up for sure, there's a fix for it

Ah Alright. I've been reading around these forums a bit and I came across a few of those threads. I wasn't sure if that was my problem though, I'm still pretty new to the phone. Thanks for the help!
No problem, glad to help

From what I am reading, it doesn't look like there's a froyo fix :/
Does that mean I should downgrade back to eclair, at least until Bell releases official froyo? If that's true it's unfortunate
did you read the 850 sticky topic?
just go into the service menu
and play with the band selection options
that should get your 850 back
I just saw that early today was added a Fastboot Package for Claro Argentina (Milestone 3 XT860) in this thread: [Fastboot Files] Gingerbread 2.3.5 and 2.3.6 for UMTS XT860 Milestone 3 (Can't link, sorry).
Here is my problem: two weeks ago I was able to access internet from my XT860 using 3G from my house, but since the 24th of December I'm not able to (2G - EDGE works good). I don't know why. If I move two blocks away from my house I have perfect reception and I can use 3G data without any problems. I already took the phone no customer's service and they gave it back to me with another blur version but still it doesn't work. I'm making almost daily calls to Claro but they don't do anything.
Currently I'm using: 2.3.4 with 5.1.790. Should I expect any change if I flash the new files?
Thank you for your help.

That sounds more like a problem with their network. I don't know why your device would selectivly not work just at your house. That's an odd software bug.

I don't know what's going on but it's weird for me too. Anyway I'm going to flash the new firmware with RSD. First time doing this with Android, any tips?

Make sure your battery is fully charged, recently another user borked his phone as it died during flashing. I have a thread called xt860, custom roms and you that has a full guide on fastboot flashing, rooting and custom roms

Well, I've already successfully flashed the new firmware but the problem is still there. That's it, I have no clue on what to do next. Thank you for your support anyway.

I think its with their network, or perhaps physical interference from something nearby. I can't think of why it would selectivly not work only at your house if it was a hardware/software issue it would be either all the time or totally random. Try mapping out the area where it cuts in/out and report it to your carrier.

I've already reported it. Several times. But they just answer "the computer shows that the antenna is working fine, you shouldn't have any troubles". I call every day to complain about it but they just don't do anything.
I hope this thread hasn't already appeared. I searched on these forums but cant seem to find a similar problem!! SO here goes: I have an issue with the reception on this phone. Incredible S S710e,
Baseband version: 20.4802.30.0822U_3822.10.08.28_M
When the network mode is on GSM/WCDMA auto i seem to lose signal suddenly even in the middle of the city. I got a few suggestions that i should flash a new radio. But while messing around a little i changed the settings to GSM only i suddenly got a very stable and strong connection even in places where i used to get a weak 1. But by doing so i cant use 3G. Only edge. And my phone was bought in india. Its almost stock. Only rooted and unlocked at HTCDEV.com . Any idea why this is??

Gsm only supports edge connection. Cdma supports hspa and hsdpa+. Not sure about your whereabouts but Cdma is usually only strong in north America.
