Hello, i live in Balkans(Europe), my SGS can connect only in cities and not in rural areas( it has no signal outside cities)
When i type *#0011# it is saying that it was connected to GSM 1800 and my country uses GSM 900, there are probably some antennas in main cities that work on GSM 1800. I tried to set it in GSM900 mode but then i cant get any signal.
I am having very difficulties when traveling.
Is it maybe a problem with internal antenna or is it software related.
The problem started when I flashed to gingerbread 2.3.3 (darky - ficeto or something)
now i have this:
PDA: I9000XWJVH
PHONE: I9000XXJVO
CSC: I9000XEEJVH
Try flashing just a modem for your area (or a different modem) in CWM or Odin. That should help. No need to change anything else.

Hi!
On one thread I read the JPP is only European then on the other it says European and US so has anyone used JPP on the USA without issues? It was rated highest in the thread that listed it as USA so I am hoping it works.

depends on the service coverage in your area. if your area is mostly all 1900, then you shouldnt have any problems with it
Jpp will work but you have to follow certain steps that noone can fully explain why it works.
Flash to stock
Flash jg8 modem
Flash jpp or jpm
These modems have support for 850 but for wherever reason it is only enabled by flashing the magical jg8 modem first.
Prior to the latest modems, this is what we had to do in order to use i9000 roms when 850 was needed.
After flashing the jg8 modem, allow the phone to boot and obtain a signal, them put the jpp modem in the rom zip in place of the modem.bin that is present. All these modems can be found in the modem thread which I am sure you know of.
Yeah I recall that process before. It seems that at home I dont use 850 but if I am at work I need it. So I cannot just flash JG8 with my current ROM and then JPP I need to go to stock? What stock is this cause stock would be Eclair so not quite sure here
Noone knows why this works but it is the only method that is proven. I don't believe flashing the modem over your current setup will work but you can give it a shot.
I have a I9000 with icyglitch kernel and extrodinary firmware both current versions. The base band us xjvu. I get poor reception with it. Been trying to put a different modem in by installing the modem zip from the recovery menu. It says installed but when I go back to phone nothing has changed. Is there a special way to do this on the I9000's
Thanks
Sent from my SGH-I9000 using XDA
make sure usb is unplugged when you flash through CWM, clear cache and dalvik before/after/both?
after testing ive found i have the same problem, trying to flash modems through CMW is unresponsive, baseband stays the same in settings-about. ive had success flashing new modems through heimdall, i cant use odin, it doesn't ever work for me.
You should just download modems from this thread
http://forum.xda-developers.com/showthread.php?t=1158783
Then put them in root folder of phone, restart phone in recovery, flash from zip, select the modem and that's it.

JW4 for T-Mobile USA? I want 3g, so i must enable 850 through servicemode, but on any modem i try it doesn't want to give me 3g i follow this
http://www.darkyrom.com/community/index.php?threads/guide-enable-850mhz-on-any-modem.3334/
in *#0011# my band is either GSM 1900 or no service, i am unable to get my radio to respond to the 850 band
So i just bought this GT-i9000 international GT-I9000GSMH flashed it with CF-Root-XX_OXA_JVU_2.3.6-v4.3-CWM3RFS.zip. Ran servicemode *#*#197328640#*#*, enabled all bands, then installed Mintberry-2.3.17 through CMW, then i tried different modems KC1, JVU, JVP, JVQ, JJPG, UGJL2, and the new nexus ones, kb3 kf1, NO LUCK with enabling 3G on my T-Mobile USA phone, can anyone help me, am i using the wrong rom? i like mintberry, any help greatly appriciated, ive been searching the forums with no avail, should i just stick with stock rom, maybe a stock+?

Guides I am following:
http://soggycashew.weebly.com/modem-dance.html
https://docs.google.com/document/pub?id=1022rpBQPDZvU0MAa0u6Nuvg3D9TGXrCIxlV8mDjN6us&pli=1
SSN: -I9000GSMH
I was told it is the international edition of the GT-I9000
I am unsure what firmware I started on, i think it was a JVT? I'm unsure, but that doesn't really matter, i used Heimdall, because Odin ALWAYS stops either at Initialization... or Setup Connection..., to flash JVU, then reverted to old USB drivers and used odin to install CF-ROOT JVU(works fine just to flash kernal), so my phone was rooted, i then installed mintberry through CMW AND GOT VERY COMFORTABLE WITH IT, then realized mintberry would not allow me to go into servicemode which would HOPEFULLY get me on T-Mobiles 3G network
So im reading the guide for the modem dance and it asks me to be on UGJL2, TLJL3, UGJK3, UGJK4, modem? firmware? WHAT? i go to http://www.sammobile.com/firmware/ and try to download ANY of the listed firmwares, oh they are all on multiupload links, and they barred themselves from USA ISPs, so i cant download the firmwares, ive searched google, found an unuseable encrypted .rar, woo-hoo... but anyways, i downloaded the appropriate modems, used heimdall to revert back to the "oldest" firmware i can download... JVU (DUMB!!!!!), install cf-root with odin, go to servicemode and enable ONLY WCDMA 850, NO OTHERS ARE STARRED, reboot, *#0011# and it says im on the 1900 band, WTF, i try to install UGJL2, TLJL3, UGJK3, UGJK4 modems through CMW, USB cable NOT plugged in, same results. So I've failed on the 2nd step of the guide...how, i doubt its user error.

So i was able to get heimdall to work by reinstalling the drivers, unplugging usb, and removing the battery for a couple min. and i installed JVU, which i seem to have to default on...now I tried the supplied passwords on sammobile on the encrypted .rar for UGJL2, a us firmware, and one worked! but when i try to flash with odin, its an odin package, i suppose i could load through heimdall, but anyways when i try to flash with odin it fails, as does the other file UGKC1, I9000UGKC1_homebinary.tar, and I9000UGJL2_homebinary_add_param.tar, so is it impossible to revert back? i should be able to do it, maybe i'll repackage these odin files for heimdall...
if i repackage for heimdall im missing boot.bin dbdata.rfs 512.pit and firmware.xml, should i pull these from the heim jvu package i have? merge them with the KG3 files, try installing through heimdall... would that be safe since odin seems to always fail on me?

do i need to flash my CSC? I know what modems are 850 enabled, i have one on my phone, 850 was enabled after i booted it from flashing modem with heimdall
i **00!!# and my band is gsm1900, and when i only WCMA 850 i get no service, ive looked at the aquisition order, which should i prioritize? GSM or UMTS? currently UMTS is, i suppose i'll give it an adjustment...
Hi, I have an S5830 (Baseband version S5830XWKT3). This phone operates on 900/2100 for 3G. Is there a way to change the frequency band to 850/1900?
I read somewhere it might be possible by flashing the modem. Can somebody confirm this? What modem should I try? As far as I can tell all modems listed on http://forum.xda-developers.com/showthread.php?t=1289830 operate on 900/2100.
Depends, the frecuency for 3g is limited by Hardware. Flashing modems is mostly to keep your Hardware defined frecuencies with correct configuration:
A Latin model ace (5830L) might not catch the correct latin frecuencies when flashed with European firmwares, so you Flash a Latin modem to make it work. But the phone won't catch European frecuencies even with European modem/firmware because of Hardware limitations. This also goes the other way around.
Most European phones have Hardware support for different European frecuencies, just flash your region's modem (which can be extracted from fiemware, just open it with 7zip or something)
Hope this answers your question.
You'll just need to install a Latin American Modem
Try downloading this one http://www.sammobile.com/firmware/?page=8&view=2553
which modem to flash
Good day gents and ladies,
What I would like to know about modems and firmware is basically which modem Should I flash if I want to change my frecuency from 900Mhz to 850 and vice versa. For example I have a Samsung galaxy ace 2 gt-i8160 with a 900 MHz frequency GSM, HSDPA, UMTS. But in order to get mobile internet in 3G I need to have the modem firmware that corresponds to my telephone model and frequency of 850 MHz.
I know I can extract it with 7zip and flash with Odin but where do I find the correct firmware so I can do this? Can anyone please help? I've read and looked everywhere for possible solutions but nothing. Also, is it possible to flash a Latin modem on my phone without bricking it? I know if I flash all the firmware with,let's say, an i8160L on my i8160 galaxy ace 2 I'll brick it... But what will just one part of it do?
Thanks an advance for your time and help!!!
I have a question I'm hoping an expert can answer. I pretty new to the Android world so I'm trying to wrap my head around a few things..
So I bought a (prepaid/locked) S5830T from a store over here, and proceeded to unlock and upgrade to the latest
stock Gingerbread firmware (2.3.6). So now when I boot up, instead of S5830T, I get S5830. All good.
Now the phone runs fine, but I have an issue with 3G data in particular.
The "T" suffix appears to relate to the 'Telstra network' (which the phone was originally locked to).
According to this link - http://whirlpool.net.au/wiki/mobile_phone_frequencies
Telstra operates on 900Hz / 1800hz for 2G and 850hz / 2100hz for 3G.
The carrier I am on (Optus) operates on 900Hz / 1800hz for 2G and 900hz / 2100hz for 3G.
So I've flash the modem file from the Optus firmware package (Modem_S5830_XWKT3) hoping that that would enable
the 3G band that is currently not working.
(What happens ins 2G/"H" works fine, but when the phone switches to "3G" I lose all data connections)
But Alas, I still have the same problem..
So I'm wondering is there hardware in the phone that is preventing connection to the network, or do I need to find a more
appropriate Modem file that operates on the frequencies above?
Many Thanks!

Can you find the original Telstra firmware, extract the modem from that and flash it?
Can you get hold of a Telstra SIM and see if you still have the same issues?
The T doesn't necessarily signify Telstra but just a slightly different version of the S5830
It's the same with SGS2 there is a GT-i9100 and GT-i9100T (I have the T version purchased in Thailand so nothing to do with Telstra)
Because I have used this phone in Australia also, I've noticed that T modems perform better on my SGS2 than non-T versions.
I've found Optus coverage (in Melbourne) to be pathetic so I always have to ensure I'm using a T modem when I'm there.

Hey, Thanks for the reply ApriliaM3.
Yeah I know the T doesn't necessarily mean Telstra, but was pretty sure it meant there was a different modem to stock (as with your SGS2).
Which is why I reverted back to stock. I thought that may have been more accommodating of all frequencies..
That's very interesting what you say regarding your T modem.
I believe I can extract the modem from my base backup, so will give that a try.
As for the Telstra sim, that might be a little harder, but I'll try the modem first and then try to get a sim.
Thanks for the info!

I get the impression that my requirement for a T modem when I'm in Melbourne has more to do with Optus and their pathetic coverage than it has to do with the modem. When I'm in Thailand, it doesn't seem to matter what modem I use... they all get good signals and I have no problem with data either. I'm also a member on Whirlpool but I rarely go there any more... still it's quite a handy and informative site for many things
Hi,
can You help me pls with ny LTE i9305 S3? I have problem with signal (antena OK, any sim any network), is just good outside but whan I go somwhere in house, is very bad or stop working network. I am not sure if can be some chip on motherboard problem, or if I solve this problem by some flash.
Thanks
Does it happen when you go inside in any place or just in your house? If it's just in your house then clearly it is just a problem of coverage on your area. I9305 international version supports bands 800, 1800 & 2600 for LTE where both 1800 and 2600 have bad coverage inside buildings. Check as another test if selecting 2g (pure GSM 900) you still have bad coverage. Can you try with a SIM of another carrier? This could also be the definitive test.
If it is a common problem (anywhere, any carrier...), then maybe you can solve it by flashing with Odin a different modem baseband (also called radio).
You have some basebands for download here:
http://sourceforge.net/projects/djb-tgp/files/CWM_Flashables/Modems/4.3 Modems/
I'm using the XXUENA2 with very good results, been used before others also with no major problems (XXUEMK1 and XXUFNI3 for example).
This is my "About device" screenshot where you can see the Baseband I'm using. Works fine in Europe as well as in Brasil:

Hi, thanks for Your reply
my problem is in house, but anyway problem with signal is without any sim always.
So I have now 4.4.4 and pls can You show me where I can download good one modem for this Android for my LTE? I´ll try it
thanks so much
EDIT: I have one. Is South Africa 4.3, there is XXUENA2 Modem, so I´ll try it and let You know.
EDIT2: So I have problem, I can´t downgrade 4.4.4 to 4.3 because will EFS faulty, so You have some idea how I can choose repair my modem for signal repair?
Hey Paul...
1) About signal: how do you expect to get signal without SIM? Or maybe are you meaning signal for just the 112 emergency call?
2) Modem/baseband: I already provided the link in my original post, check it.
3) No need to downgrade. You will only flash the modem/baseband without touching any partition, neither the ROM nor the EFS. You can do that via Odin (check any Odin How-To document -search Google-) or via the recovery if you have TFRT or QWM (at recovery menu select flash zip file and choose the one for the modem -you need to copy the zip file previously to your sd card or internal memory).
