(Resolved) Unable to connect to 3g with good APN, after flash

Hello all and thanks for your future help
So today i flash a friend's SGS, his phone run on SFR network (from france) with the DJP5 firmware with the combo fully fonctional.
So i flash a JM5, then the JS3 and i flash my rom kitchen from doc, custom JS3 with JPY modem and XEF CSC.
All is fine, the phone reboot, I flash speedmod Kernel k13a, reboot and set the good network and BAM.
Could not connect to 3g whatever i do.
I try different APN, then I reset to the first one (normaly the good one) but nothing.....
I try different modem (JPE, JPY and JPX) nothing work at all, i'm unable to connect 3g......
First time i see this problem, even if i flash my phone ten time a week.....
So I hope you could help me
Thanks in advance !

Nobody can help me? No idea?

I have the same kind of problem with mine. APN info is perfect. Settings are for GSM&WCDMA. I have no problem with WIFI and EDGE works fine so it'll still transfer data. It's with Darky's 9.2 ROM though so it may have something to do with the JS3 firmware customisations.
I've cleared cache and dalvik cache as well and I get the 3g symbol up for a moment but when it actually starts to transfer data, it switches to EDGE.
I'm re-flashing Darky's firmware without wipe just to see if it's an issue with my altering twframework.apk for a cool notification window background. I'll pop back on this one tomorrow and let you know how that went just to see if the first one was a bad flash. I have read that there can be more issues with flashing through CWM then through Odin but I think I'll wait and see if that's necessary.

hey i got kinda same problem..!!! :-| i have SGS i9000 in India...today i installed darky's ROM for the first time...installed 9.2 extreme version....but after that i just cant connect to a data network...not even Edge network.... if i update APN settings manually & reboot...still they are not saved...tried switching data network on & off million times also switching flight mode on & off....in hope that it will connect to my data network but just wont work..!!!

Have you all set the user names for the apn settings? I wasn't connecting either until I verified the usermame and password were correct.

Ok, here's the problem. It's the CSC. I know it bites but you're going to have to go through a system reset. The custom firmwares come with multi-csc (wipe versions) so enter your dial pad and type *#272*(your imei)# then select a CSC for your country or something like XEU which is what I did. Then, enter recovery, clear cache and dalvik cache. Finally, re-enter your APN.
Hope that does it for you. It worked for me as my CSC was XXOJPY (Darky's ROM) and set to KOR. I know I'll be keeping this in mind the next time I flash a new wipe ROM. Oh and do a backup beforehand, just in case.

There-in lies the problem. Generally it's a "set it and forget it" kind of thing but in the case of a rom that's going to wipe everything, you need to reset it.

Thanks for your reply! I
I've got all my apn 's settings right but I found a solution. The csc was multi and flash by the rom, so I flash and xef csc by odin and it works for me
Maybe it work for you
Thanks again for your help!

[Q] (Q) No 3G signal after returning to XXJPY, any ideas?

Hello guys!
After getting this phone from a friend i have to return it to stock Froyo XXJPY, coming from MIUI.
I managed to get it back to XXJPY: PDA: I9000XXJPY
PHONE: I9000XXJPY
CSC: I9000XAJPY
Problem: I'm not getting any 3G signals!
And KIES isn't recognizing my phone as something i could flash to the next official update.
Can you guys help me out here? Im not a pro in flashing, though i can learn pretty quick.
<edit> i'm from the netherlands, on Vodafone. (if that matters)

Check your APN settings.
I live in the Netherlands and have a SGS from Vodafone to.
Do this:
"Instellingen -> draadloos en netwerken -> mobiele netwerken -> Namen toegangspunten"
Then press the menu key, en click "nieuwe apn"
You can find the settings here:
http://www.vodafone.nl/zakelijk/kla...n/Instellingen_per_toestel/?#settingslocation
Merk -> Samsung
Model -> i9000 Galaxy S (onderaan)
stel het toestel in voor: Internet op je mobiel
Then there is a small button at the bottom saying "Handmatig instellen? Toon mij de instellingen"
Click it, and there will be the settings you have to enter.
This worked for me too when i flashed using repartition.
Mathijs
PS: if you want to go to JS5 (XEN), here's the download link for ODIN & CWM:
http://www.androidworld.nl/forum/sa...-froyo-xwjs5-flashbaar-via-kies-odin-cwm.html

Okay, thanks!
But is was wondering... I used the EZrom to get back to a sort of stock rom to eventually flash jpy.. But i only did repartition with flashing EZROM... Not with XXJPY...
Is that where is has gone wrong?
Also...when connecting to kies, when i want to look if i have any updates, it tells me CSC: JPY (KOR)
I am not really familiar with this problem, and i haven't ever read or heard anything like this.

Okay, i followed your advise and flashed JS5.
Partial Succes!
I am getting a 3G signal, so that half of the problem is solved!
Now the KIES part:
KIES tells me I still can't update my phone to any future updates..(2.3??)
At Current firmware version it says:
PDA:JS5/ PHONE:JPY/ CSC:JS3 (KOR)
I believe that the CSC is the problem here...could it be?

When playing with roms, it sometimes happens that the productcode gets set to KOR.
I've had something like that ones, but my product code changed to XEE.
I just flashed a dutch firmware like you did, but i factory resetted, then my product code changed back.
So i would suggest you to do a factor reset.
However i'm not 100% sure if it will solve the problem.

I just did, no luck so far.
And it's only CSC on KIES that says; KOR
If anyone can shed some light on this matter?
PS:I want to give a HUGE shoutout to anyone here at XDA for providing the right tools to break free from the leash Samsung/HTC/SE etc. hold us on.

It is the CSC that Kies reads and knows whether to update or not. If you want to do it through kies you have to get the right CSC for your area.

You could try this
dial *#272*imei#*
put your imei in where it says imei. It can be found under the battery.
doing this will show your product code and may also give you the option to select a different one.

APN Settings problem

Hi
My APN settings won't save
I just upgraded my firmware to 2.2 from 2.1
I have a Galaxy S phone
When ever I try to add the settings it won't display the setting & I can't connect to the net through my phone
I m from India & I updated my phone by rooting it & then installing the firmware from Odin
Plz help me

You must manualy input data of your providers APN, like new APN, than save it. Probabily because you have device with different CSC from your region ( India), like me, i have HKDDBT (Germany), and must after evry new flash firmware manualy input APN...
Or you can easy make this with this apk:

Abhishek,
Just a thought. why dont you try installing JVH / JVO 2.3.3 firmware throught Odin. I have these firmwares and its great at the moment. you dont need to manually add APN files as its automatically detected in these newer CSC firmwares.
else install JS8 2.2.1 if you are into serious gaming.

can you tell me from whr can I download them??

I fixed my problem
I downloaded the 2.1 firmware [Asian firmware for my country] from sammfirmware site & downgraded my phone from 2.2 to 2.1 then I got my APN working & my CSC was restored to its original value
Then I updated my phone to 2.2 using Kies & Now I have the official 2.2 android firmware without any problems
So my problem is fixed

Galaxy Tab problems after stock restore

I had a UK unlocked (no branding) GT-P1000 Galaxy Tab. I flashed it to a custom gingerbread build on Win7 X64 but later wanted to revert to stock. After a lot of searching I flashed the device with P1000XWJMI. All went fine and device booted back in (with a foreign language set as default but I've changed to English via settings).
When connecting the device to Kies it now says "This version of the device cannot be updated". It never used to say this before! It used to say I was running the latest firmware.Can anyone advise what the problem is?
I've seen some threads referring to something with a CSC mismatch and to alter using *#272*IMEI# and changing the code but I didn't want to do this without being certain what I'm changing.
Presently Kies shows:
PDA: JMI
Phone: JMA
CSC: JM4 (CPW)
I'm running Kies version 2.0.1.11053_99
Thanks
Craig

Is JMI stock for your tab? Besides, the country code might be wrong.

I didnt know how to find the correct stock for this tab. I just saw in a post that someone else form UK had used this so I went for it.

i had this issue also , and i didn't know ever how to make it work
so ppl said that you have to download app from the market that plays with the PDA and CSC to change them to what ever you want without flashing any other rom
Darkpal guide :
My way is DANGEROUS. You need to know what you're doing to do it. IF IT MELTS YOUR TAB am not RESPONSIBLE.
1. Do a Rotobackup of your existing firmware or any backup to your efs folder (regular backups won't work).
2. Download an app called SpoofFW
3. Put the PDA, Phone and CSC of a known stock firmware (like your asia
4. reboot.
5. connect to kies.
thanks for him not for me , but to your info i couldn't understand what to do with the app maybe you wait someone to describe it for you

Do you know when kies said latest firmware what was your firmware then?

My case is different. After updating my ROM back to stock, all the versions are OK, despite the software and phonebook remains (but I noticed that my photos in gallery are deleted, which is what I wished).
My question is how to restore it to the REAL factory setting state, without any additional wallpaper and software that I installed?
Thanks for your attention, and wait for your advise as well.

If I understand you correctly, you have to:
[*]Press menu
[*]Settings
[*]Privacy
And there you'll have the option to do the factory reset.
You can also do it by booting into recovery (volume up + power on) and selecting it from the menu.

My tab is from the uk (got it from amazon uk) and it was jmi/jma/jm2 (cpw) on the last update. Before that it was jj7/jk5/jj5 (cpw).
Maybe you can try downloading an older euro rom from samsfirmware and go from there. Don't forget jmi had locked bootloaders.

[Q] CSC Unknown

I installed a rooted rom on my s3 mini and all was good. I then installed a csc changer to check what my csc was, when I seen it was SEB I changed it to BTU because I am in the UK. But when the phone rebooted the csc was "unknown" and the csc changer was showing it blank. My problem now is that I have all my back ups on Kies which now will not see my phone. I have searched, found and tried many solutions to this all to no avail. I tried the original SEB unrooted rom, still csc unknown, I tried various rooted roms and none would let me change the csc no matter what app I used. Any help with this would be greatly appreciated.

try to reflash your ROM with odin as "CSC" not as "PDA" then it should show your right csc code again.

I had this exact same problem when I flashed rooted XXAMA2. All i got was CSC:unknown. Couldn't change it with csc changer.
I had to go back to stock recovery and then flash firmware again with Odin, then I could set right CSC.

Have you tried SAMSUNG GALAXY S3 CSC SELECTOR on Play Store, just download/install/run and choose your code, then it works!

Has anyone a link to stock recovery? I´m in a hurry, sorry mates... wanted to get my wife´s S§ mini back to working but nothing helped until now.. will give it a try with the stock recovery and reflashing a Sammy ROM. Sammy ROM´s not a problem, but where can I get that recovery only?!

Thanks a LOT, mate!! That´s what I was looking for
Downloaded modem, stock recovery and TWRP now. Unfortunately I couldn´t get the modem back to be shown as it is (after a ROM update modem changed to XXXX ....... since then IMEI was working though, calls were working too but no mobile internet connection) but mobile internet seems to work again now, too... Very curious so far.
Restoring EFS didn´t work but maybe it will work now as CSC is changed back to DBT now or so.. Sometimes flashing Sammy ROMS as PHONE instead of PDA does work (read that in another thread in here).
Thanks again for your help and have a nice evening!
Cheers!

Well the problem is partly solved.. I flashed stock recovery, stock ROM and that modem you can find in tys0n´s signature. Mobile internet is working again but modem still shows XXXX - weird thing ^^
Give it a try in that way. As it seems this is a possibility to get your device working again.
I´ll continue trying and if I find a way to solve it finally I´ll let you know.
