?? about modem for captivate galaxy s - Captivate Q&A, Help & Troubleshooting

I rooted and installed serendipity rom and wanted to flash modem ....Is it safe to flash any modem spicifically this modem_cwm3_ugjl2 just making sure before I do and I don't want to mess anything up thanks

I checked this page http://forum.xda-developers.com/showthread.php?t=876391 but Am really not sure which modem is safe?? for my galaxy s captivate atat phone

LOL trying to get to 10 posts so I can post in the modem forum LOL

for that rom, since it is i9000 based, you can safely flash that modem, assuming you have CWM 3 installed and not 2

You can safely flash any modem, there is absolutely 0 chance of permanently damaging anything.
The only issue you could have is if you are on an based I9000 rom and flash an i897 modem, or vice versa, there will be sound quality issues.
So as long as its I9k to I9k, and I897 to I897 it's fine.

I would like to enable WCDMA 900 Mhz (and no longer use 850 Mhz). The Infineon baseband IC is capable of 850 or 900, but not simultaneously, however I can't determine if a "modem" can actually re-program the IC for 900 Mhz?
If anyone has any advice or pointers I'd be most appreciative.
I could install any ROM/modem combination in order to enable WCDMA 900 Mhz.
I am currently running Paragon RC6, a 2.2.1 custom ROM, with I9000UGJK4, which has 850/1900/2100.

So its JPP modem compatible with the USA or not? I keep reading different info

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.

[Q] What modems are compatable with stock AT&T FROYO KB1

I am running stock KB1 with injected voodoo lagfix. I am tring to disable the 1900 band and use only the 850 band because I lose service in my area when my phone switches to 1900. This happens every few minutes. right now im using the stock modem that came with KB1 and when I try to enter band selection in the service menu I get a this option is restricted error. Are any of the other modems compatible with KB1 that will bypass this restriction?
Thanks

Well i just Flashed the UCJI6 modem and it seems to work with KB1 but the band selection is still restricted. Any help would be apreciated.
if you want a good selection of modems you can flash a i9000 reoriented kernel and that will allow you to use i9000 modems ( of which there are many good ones) and still use your current rom.
i've not used stock ROM so look into which kernel is best. read lots and lots.

[Q] Weak/No Signal after upgrade to 2.3.4, root and unlock

I have a SGS GT I9000 from australia, and I am trying to use it in the US for AT&T. I have rooted on JVR (via CFROOT v4.1) and tried using modem binaries for KC1, JL2 and KG3, all seem to find minimal signal when I am in the street.
I have manually unlocked the sim settings using adb. I have enabled the 850 mhz band in the settings and have seen the *#0011# showing gsm on 850 mhz.
Frankly I am lost now because I have no idea what could be causing the issue anymore. The sim works fine in my other phone, if anyone can shed some ideas I would much appreciate it.

Modem Issues

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.

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...

Change 3G Frequency Band from 900/2100 to 850/1900

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

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!!!
