Galaxy 2 always losing 3g / data - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I have lighting rom 6.1 installed XXKH3 (what this means?? XXKH3??), I have a Samsung Galaxy from Portugal and my 3g / data only works when I do a factory reset and in next boot it goes away. Even if i try to create an APN it crashes when i select New APN. I tried to change the CSC to TPH (portugal) with the *#272*......, also installed a MultiCSC OXXKE2 because the lighting rom didn't bring TPH, and also copy the CSC portuguese files with a .zip in recovery. First time after selecting TPH in *#272 everything works good, but next reboot stop working again. I checked with *#272 that TPH is selected and i don't understant what is happening. Please help because i can't use internet.
Thanks,
Raven

Try a different modems and find out what works the best for you. That would be my best bet.
Most roms included a modem and it is possible that the modem you use is not the best for your location. I don't why chefs always include a modem in the package, because the modem version that works best for you, will probably not work as good for me.
In this case, the latest modem does not need to be the best.

[Q] Update radio (modem) only?

Hi,
I've had my Samsung Galaxy SII (GT-i9100) since around 10th of May this year. It came with a firmware ending with *1, but the first thing I did was to upgrade it to XWKE2 via Kies on my PC. That was a good firmware. I had no problems with it ... The only annoying part was that the camera made shuttersounds all the time, even when the phone was silenced to vibrate only. That was fixed in XWKF3 which I'm running now. The MAJOR problem with XWKF3 is that the radio/modem is ****ed up beyond recognition.
On KE2 I had like H or H+ all the time, and if no H/H+ I had E. Nothing in between. Now I see 3G almost more than I see H/H+, even though I'm in the same areas as before. Also when my phone goes toggling between 3G and H or stays on 3G - I do not have Internet access. It's like a huge "no route to host" appears on 3G, or if the phone toggles and cannot agree on ONE thing.
So I would like to upgrade the radio only. Why? Well I've been trough a few of the original firmwares from samfirmware.com and here, Mostly XWKE2 (which made my phone loop on boot), XWKF3, XXKG6 and XWKG3 (I think). Main problem with XXKG6 was that it didn't have Norwegian (for Swype or keyboard at all, but UI was present in Norwegian). Others was either looping on boot or I was using them to upgrade back to the original firmware (now XWKF3 with radio XXKE7 and XXKF1 for CSC).
Two questions ... Can I use Odin (I've got 1.85 as the latest) to upgrade ONLY the "Modem"-part? From XXKE7 to XXKG6?
Is there a way to get Norwegian Swype on the XXKG6? Maybe "keep" an older NEE-based CSC? Because .. Swype is a part of CSC not PDA/Code, right?

Yes, you can upgrade the modem separately.

swpye is not part of the csc, the language only is part of the csc.
Swype is app that can be updated or installed seperately and has links to the csc.
Untar the file using something like 7-zip.
Just use the modem.bin, and tar it back using 7-zip, flash with Odin under phone.
If not, you can download one of the Clockwork version, and replace the modem file, then rezip and upgrade with Clockwork Recovery.
Flash your Modem KG6 and Flash CSC KF1 for your area Modem in Phone and CSC in CSC via Odin . A CSC is only a bunch of text files with network details language etc .
jje
So summarized ... I can use Odin and _only_ tick "Modem" and pick the XXKG6-Modem, or do I need a CSC as well? I have today the Stock XWKF3, with radio XXKE7 and CSC KF1. The only ****ing thing bothering me with this stock rom, is that the radio went FUBAR after update (compared to how it behaved on XWKE2)

So ... With XXKG6 (to differ from XWKF3) I will not get Norwegian Swype, even if I custom with Odin to keep my KF1-CSC? I will have to wait for a XWK*-release of Android 2.3.4 to have my Swype with norwegian dictionaries?
you can flash the modem only.
csc is used in relation to your swype question.
Will do a flash of my radio later tonight after work then. I really hope it goes more stable again. Samsungs Customer Service is crap ... "Have you tried to reset your phone?" - "Yeah, your radio software still sucks!" ... "Well sir, try to fabric reset your phone" - "Say that again, and I will strangle you!!" ...

[Q] Need Help Activating Data!!!

I have been using Exynos Extreme rom for the last couple of weeks and recently updated to v5.4. KH3 rom with latest speedmod kernel and KH3 radio. Everything seemed fine until a couple of nights ago i lost the ability to switch data on at all. I can check the "Use packet data" box in mobile networks but the 3G or H icons fail to appear in the task bar!!
I have tried absolutely everything possible to enable mobile data again but, to no avail. I've wiped cache, wiped dalvik cache, tried KG3 radio, then back to KH3, reapplied the apn settings in "Access Point Names", tried toggling flight mode on and off. I then went on to perform a complete data/factory reset which, still wouldn't fix the problem. So as a last measure, I installed the latest stock rom "GT-I9100_XEO_I9100XXKH3_I9100XXKH3_I9100OXAKH3" in the hope that it would finally fix my problem. Well no luck thus far, reapplied the apn settings again but still no luck.
I also checked info in "About Phone/Status" and noticed that "Mobile network state" shows as "disconnected".
It seems I've completely exhausted all possible solutions and I'm at a complete loss as what step to take next. I would appreciate very much if someone on here could help me finally fix my data woes.
what kernel and modem version do you have?
if they are other than KH3. try flashing KH3. you can go with the CF-Root KH3 kernel
Was originally on KH3 radio and latest speedmod kernel with Exynos Extreme, then flashed to stock KH3 rom with KH3 modem and KH3 kernel. Also tried with CF-ROOT KH3 kernel. All are giving the same result. Now I've reflashed Exynos rom KH3 with KH3 radio again but still no luck.
Also forgot to state that I tried KG3 radio with Exynos KH3 rom before I performed factory reset.
did you try reflashing the csc for your region.
csc contains the information needed for data settings.
try one of these codes.There is quite a few data options amoung them.
http://samsunggalaxysforums.com/showthread.php/4701-Galaxy-S-i9100-Secret-Codes
if all else fails re-flash and try the cognition s2 rom.Seems to be quite popular with this firmware and with alot of happy users.
Happened to me the other day but on villain rom, I'm on O2 by the way. I had to go into my APN settings and restore the default then the data started working. I'm still trying to work out what changed or messed up the settings as they have been working fine for several months.
Hi and thanks for your suggestion. Not tried that yet as i was unaware what the csc file does. I remember seeing links to those files in the "stock rom" thread but can't find that thread now lol. Any pointers or links for the csc files thanks?
If you have no CSC file network will connect using manual settings .

Thanks for the pointer but, I'm a bit daunted by the sight of so many csc files lol. Really not sure which one applies to me, I'm on giffgaff network that runs on O2 UK masts. I have the apn settings all input correctly but really not sure which one of these csc files would apply to O2 UK.
xeu uk csc applies to providers in the uk.
Happened to me once. Just go to wifi-network in settings and put in manually your APN settings, get them from your cell provider.

CSC, Photo (low batery) and Flash Question

Hello!
1)
I have actualy flashed KF3. When battery goes down to 19% its not possible to take a Photo. Every time i start the Application there is a promt with low Battary warning. What the fu** ? I want to make a picture when i want, and not when andoird allows me to take a picture! If i turn off the automatic power managemend, its the same.
So any ideas to avoid that?
2)
I have flashed KF3 XEU firmware and want to update to the actual XWKI4 DBT (its original a DBT device). So, after flashing with odin, whats with my settings and home screens etc.? Have i reconfigure everything?
If everything is los, how can i make a backup of all my settings?
1) That's normal, you need as hacked camera.apk. Look here http://forum.xda-developers.com/showthread.php?t=1104051
2) All the ROMs posted are non-wipe, unless when stated, so you won't lose your data.
Perfect thank you!
Hi, my current fw is uhkg4. Can I flash to ki3? Are there some restriction?
No but KI3 is not official and bootloader no longer lets us clear custom rom counter with usb jig .
jje
So, i flashed my XEU KF3 with DBT XWKI4 but, after flashing my CSC is still set to XEU.
How can i Change my CSC to DBT?
*#272*Device IMEI# doesnt offer my DBT for installing.
I think a factory reset will do fine ore?
Any ideas how i can backup and recover my settings after factory reset?
Second problem:
After flashing mini paper widget doesnt work
Cant write anything in the widget.

[Q] No Mobile data after custom rom install

Hi, i installed the Omega v41 rom in my galaxy s3 i9300. I had the rooted stock rom, and installed omega with cwm after a full wipe (wipe data, cache, dalvik). After the install, i used titanium backup to restore my apps. Tested the wifi, phone, sms, restored apps, and everything worked fine except the mobile data connection. So i read the forum and found some ideas, like erasing the APN settings and manually adding them later, but nothing worked. So i'm to re flash the modem to UBELL1 (from this thread) which seems to be the modem version for my area (South america, Argentina with the provider-> Movistar).
But my question is, it's necessary to re-flash the modem even if the phone and sms are working? O should i directly flash another rom or restore the stock rom backup?
you can call your carrier for the apn settings

I have the APN settings. So that's not a problem. And my friend who also have a galaxy s3 with the same company, uses the same settings. So it shouldn't be an APN setting problem
Do you have an IMEI and baseband?
Sometimes, this happens with corrupted IMEI folder.
Are you sure that your provider isn't having some problems?

I checked that, my IMEI is the same as the one before the rom install. And the base band is I9300XXELLA, the one from the Omega rom, so this is Ok also (no?).
The weird thing is also that when i send an MMS text i see the 3G connection indicator, but when the send is finished, the icon dissapears.

There is a very buggy situation with PDA XXELLA and latin american baseband that start with "UB" basically UB basebands or MODEMS are optimised for Latin american BANDS
So regardless of the Modem you have XXELLA is just not to friendly with Latin amercas BANDS...
i Have XXELLA PDA and i have tried several modems my suggestions is download PERKAS File Share from Google Play store and download and after installing it get the APP GET RILL from the Google play store and install the RIL for your modem
Modem XXELKC (i wont recommend you go anything lower than that other wise youll be using a 4.1.1 modem) after installing the modem Add the APN settings.
Try to extract an Modify the CSC from Movistar your Original carries ROM as i did...
i had the same situation as you had XXELLA PDA with ella and UBell1 modem and still buggy.. so i am on XXELKC and its Stable..
All i am hoping is that EMA and EMR are better with basebands..
Espero te ayude en algo amigo saludos
I tried with XXELKC, and i still have the same problem. Everything works (even MMS) except the data network. I think i'll try to restore from the original backup to see if i can extract the original CSC. I don't know what else to try really...
In another of my "tests" i tried to set the APN type to internet, and the 3G/H indicator appeared, but it still doesn't work (even though it drains battery like water).

[Q] Losing signal due to new modem? Your thoughts?

Hello, I hope everyone is well and good. I apologize for the long post but I figured if I explained my problem in detail it would be better.
I have a samsung galaxy s3 i9300. My phone is rooted. There is a specific problem which I have been facing for months now and I have done A LOT of research on it but still cant understand it/fix it.
Basically, the problem I am facing is whenever I flash a ROM which changes my modem/baseband (such as Omega/Ultima), I lose connectivity to my carrier. (I live in Pakistan ).
I have tried the following when that happens(All during my Omega flash):
1)Check if my IMEI is intact. It is. (I have EFS backups too)
2)Check if my serial # is different. It is still the same (No need for Ariza Patch)
3)Check if my SIM works. It does on different phones.
4)Check my APN settings. They were fine. I even manually changed them to match the carriers
5)Change my CSC settings (using the playstore app). Still doesnt work.
6)Check different modems from the appropiate thread (I have tried Europe Unbranded, Middle East, Egypt and many others)
7)Restored nandroid backup of original stock 4.1.2 Sammy ROM, still not connectivity.
8)Flashed using ODIN, the stock 4.1.2 ROM for my country (Using SAM mobile)
And every time that happens, I have to send in my device to my local repair shop which takes about 4 days for me to get my device back. I am currently on Paranoid Android 3.57 but the camera connectivity problem makes me want to pull my hair out. I would like to go to OMEGA.
So before I go back to Omega and try again, I think I have figured it out but needed someones opinion on it. I understand I should test is myself first but I really need my phone for the next month for personal purposes so need a green light of sorts . I personally think since everything else is fine, maybe there is an issue and incompatibility with the RIL and the BASEBAND. According to GetRIL app from the playstore, my RIL and Baseband do not match.
RIL: I9300XXDLIB
Baseband: I9300XXELLA
Recommended: I9300XXDLIB.
Can this be the cause of me losing reception to my carrier? (This screenshot was taken on Paranoid Android)
Heres some useful info on what makes my phone work on stock:
AP: I9300XXEMA2
CP: I9300XXELLA
CSC: I9300OJVEMA1
Attached are also pictures of my settings. Thank you in advance. Please help me out someone
EDIT: The two stock screenshots I have attached below are when my s3 works perfectly fine. And the last Paranoid Android screenshot shows that as long as I dont change modems/basebands, my phone still works.
The RIL comes with the ROM and often don't match if you change the modem. I really doubt this is the problem.
You should never need to touch the RIL, but definitely never touch it on an AOSP rom.
Only use getRIL on samsung ROMs

So I can use the GetRIL app on Omega since its a samsung based ROM?
Any idea what could be the problem?
Yeah definitely can use on omega.
Really not sure what the problem is. Maybe efs gets a bit corrupt? Try using philz recovery and backup efs before flash?
Make sure you format system before flashing.
If you have a baseband that works best, keep it at hand to flash.
If aroma installer allows you not to flash modem, choose not to.
Also perhaps try aosp camera mod by theunknown in themes and apps for s3. Maybe you don't need to.leave PA....

I believe I have seen a very similar problem on a number of phones - your EFS database is "strange" (it was unlocked with some very old version of unlocker) and it needs a very special version of patched modem to work - check the ariza thread - and install the ariza patch even if apparently it is not needed!
I do format system and do a full wipe before installing ROMs.
Okay I will try the ariza patch. Just waiting to get a microsim adapter so I'm not left without a phone .
Last question. Is there a way to backup my current modem(through an app like titanium backup or otherwise) or manually insert my current modem into omegas or any other ROM? Or I force my phone to keep my modem between ROM flashing?

The best way is to remove the modem bin file from the rom zip and the lines in the install script file (generally the script is commented so easy to find) so your modem will be unchanged.

Can you please explain it a little bit? Basically after searching online, all i understood was I open up Omega's zip using a program like 7zip, navigate through and replace the bin file with my stock one?
But I dont have my stock modem in zip format. Its in the form of a nandroid..
No just remove it. There is no need to have a modem file to flash a ROM. Then go in the script installation file and remove the lines that flash modem to avoid errors during flash process. Or just remove the lines without removing the modem file it won't be flashed.
The script is in Meta-inf>com>Google>android. Generally there are comments so the lines to remove are easy to find modem is generally flashed at the end of the script.

Okay so i just realized one thing. When i installed omega right now, and tried to change the csc using the app to my country, it reset my phone like it was supposed to, but did not change the csc. What does that mean? I dialed *#1234# and the csc remained the same. This is my original stock settings:
AP: I9300XXEMA2
CP: I9300XXELLA
CSC: I9300OJVEMA1
The current settings are:
AP: I9300XXEMF1
CP: I9300BVEMF1
CSC: I9300ONEEMF1
I used the csc changer app from the playstore. The changing the csc using the manual *#272*IMEI# does not work for some reason.
