I would like to know what is the difference between Phone and CSC on Odin 1.85
and also would like to find out whats the right phone and csc for my phone, after I rooted I lost complete mobile network reception inside my home.
I'm on giffgaff, which runs on O2 network,
before I rooted my kernel was xwkj3, and I had xwkj1 I think for my modem, but I don't remember
I have rooted using this CF-Root-SGS2_XW_XEN_KJ3-v5.0-CWM5.tar
after I had a read around this was the right modified kernel, but since then I can't make calls or receive calls inside my house, only when I'm outside, and what strange my gf has an htc hero, with giffgaff simcard, and her phone always have reception inside the house, like my use to, I know is not the sim card, as I have tested on her phone and works like hers 3 bars, and I have all the mmsc and apn all setup accordingly to giffgaff, so I know is not that.
narrows down to the wrong CSC or Modem, other than that I can't figure this one out, and I have flashed and reflashed with odin several times, I don't even bother updating my software and apps, cause I know it will all be gone from my internal mem card,

in the most sammy roms , CSC is included in PDA zip or .tar , try CheckFusDownloader_v2.1.exe , and search for original ROM for u'r network , download it and flash it with ODIN 1.8

Root has nothing to do with network .

Any modem will work on the Giffgaff network .
after I had a read around this was the right modified kernel, but since then I can't make calls or receive calls inside my house, o
Thats a fact of your network or possibly modem .
narrows down to the wrong CSC
CSC nothing to do with it especially if you have set network manually or via the Giffgaff apn settings tool .
Suggestion would be to flash the KL1 modem .

Hi,
I'm new to both this forum and android, just switched from iphone and already running into the same dead end that I was trying to avoid. Hope to get some suggestions on solutions before trying sell it off again...
I bought a second hand SGSII which is from the UK (T-mobile), and with the help of my brother who has a SGSII and have been on android for a while, I debranded/rooted changed ROM, Kernel and Modem firmware. Before doing this I noted that it did not work with the network I am on but it did with another (both Swedish). After rooting etc I tried again, still does not work (I've tried several sims from my provider, none of them work, still only the other provider). I tried using the Sim Unlock app on Market but it is of no use: It DOES NOT ASK for a sim unlock code on start up. In fact, the unlock app worked and gave me such a code but I cannot use it. Also, I tried plugging in the code using a few of the call codes but it was of no use. And when I put *#SIMLOCK# into the phone dialer everything says 'off'.
Does anyone have any idea of what to do? I cannot go back to Samsung as I do not have a receipt. I hate to think that I have to end my use of Android before it ever started but I have searched my problem for days on end and neither me nor my brother can think of anything.
Any help most appreciated!

I am confused did you buy an unlocked phone . If not did you get it unlocked .

JJEgan - sorry if I was unclear. I do not actually know for sure, but as I have never seen the screen on startup where it asks for the unlock code I suspect that it must have been. It now - same as it has been for as long as I have had it - works only with one network which has nothing to do with T-mobile (on which is was originally).
I only know of one way of unlocking, i.e. the unlock app on Market. If there are others I would be very interested!
Phone may require you to enter the networks APN settings manually .
You may not have the correct CSC file for your network for automatic connection ,

Hi - been busy the last few days and unable to try getting the phone to work. I cannot enter the APN settings (which should only have to do with internet?) as I cannot connect to any network in the list - I get "unable to select network". I've tried multiple official firmwares with both only NEE (Nordic) CSC and multi-CSC (where I chose NEE) and none work. Any other ideas?

Hi,
I´ve been having a serious issue with my phone.
- I´m not using the phone, people call me and get a busy signal.
- I´ve tried calling my self from a landline and realized this is true.
- I´ve tested calling my home´s landline and got a weird beeping sound and then the call was not completed.
- I´ve rebooted the phone and the issue was fixed, but after a while it reocured.
Any thoughts on how to fix this?
I was just wondering if its a SIM issue (rather than phone). Maybe try a different SIM and see if there's a different result?
Sent from my GT-I9100 using xda premium
- I´ve cleaned the SIM card and the SIM card slot, put it back in and made a couple of teste. I keep getting the busy signal even when the phone is not being used. Now even after I reboot the issue sometimes happens....or if it doesn´t happen it starts happening after the phone goes to sleep.
Could this be the phone´s modem? This is a serious issue.
You can flash a new modem from the modem thread .Or ask for a new sim card .

I got the lastest "Test Mode" firmware from the program "Check Fus Downloader" for you.
Product Code: GT-I9100LKAEPL
Latest firmware: I9100XWKF3/I9100EPLKE4/I9100XXKE7/I9100XWKF3
Is this the correct one??? If so you could try the following if you already have root and CWM Recovery installed;
Type into your phone dialer *#1234# and write download your existing 'Phone' (Modem) version, just incase you wish to reflash that.
[MODEM] Main modem XX versions flashable through CWM
Immediately before flashing, I suggest you take nnote of signal strength; Phone Menu / Settings / About Phone / Status, you can then compare.
Download the closest matching modem and flash through CWM Recovery. The closest I can see is XXKF2.
If you still have no luck, could also try the latest one as well. Be aware for any change in signal strength, quality, not obtaining 3G, H, H= etc.
Hope this helps
Please, Please, HELP ME !!!
I looked all over this forum and on the net to try to find a solution to my problem, but I couldn't find anything that relates to this issue.
When I go into Mobile Networks/Network Operators, the phone starts to search for available networks. When the search is complete, I select the network I want and then I get the following message: "Unable to select Network/Select Automatically. Unable to connect.Try again later." The only way I can connect to my provider is to reboot the phone. Because of this, I am unable to use my phone in roaming either. It looks like my phone fails to connect to any mobile networks manually.
When I put the SIM in a different phone, the error is gone, so the problem should be with my phone. Could it be a modem or a ROM issue? Don't know.
The phone is rooted, with Android 2.3.5, Baseband: I9100XXKI4. Kernel version: 2.6.35.7-I9100XXKI4-CL611039 [email protected] #2.
Please help me. All help will be greatly appreciated.

Almost always helps
Set network APN manually do not use search /auto and see what happens .
That can be followed by backup of data and factory reset .
You can also check you have correct CSC for network/location .
Next would be to flash another modem KI1 for choice through Odin or from the zipped modems post through CWM .

I had the similar problem since last week: The sgs2 has been working with local operator Telia for about 4 months and suddenly it could not register on the network after I have set it to airplane mode several times
I put 3 other sims from the same operator in my sgs2, all of them do not work, and they all working fine in other phones
I put 2 sims from 2 other operators in my sgs2, they all working fine
So it seems this sgs2 only does not work within Telia's network, but I gave Telia support my IMEI number, they say that number is not locked or blocked in their network
I tried manually select network from the list, but get immediately back a notification saying "unable to select network", not like in a working phone, it takes several seconds before getting a confirmation from the network
So I guess some old denying answer from Telia is cached in the phone, and everytime phone send the register request, the cached denying answer is read. unless I can clearout this cache, there is no way to get registered with Telia
I went forward to wipe/factory reset/flash another rom&modem, all did not help. I guess these cache information is not changeble through normal flashing process, maybe in EFS area or somewhere else
Anyone can help?

I'm sure this is not your situation but my provider was down for the days but when I called support they swore everything was fine and trouble shooted my phone.for what ever reason their Sim showed every provider in my area as them.(as it in network search all providers looked like my provider). While the phone tried to connect to the other providers it was rejected as "unable to register on network"error. I did not figure out out until I checked network search with a different provider Sim and my network provider was no where to be found until they got the system back up in my area.

Thanks, I always flash stock roms and csc for the phone, and tried twice, I believe the data which caused the problem could not be touched by the flash process
Now I put another SIM from telenor in the sgs2 and try to manually select the Telia network, it took more than 30 seconds and returned a message saying "unable to select network, select automatically", and then it select home network (telenor) successfully
However, if I manually select other non-home network (3, tele2 etc... ), it took about 5 seconds to get that message
So, I think that 30 seconds waiting actually is a system timeout period, there is no communication to/from Telia network during this period
The strange thing is that even reflash the rom/kernel/modem do not improve the situation, where did the android system store the settings of network operators so that even a full flash of the phone can not clear it?
I'm going to do some adb logging today to see what is actually happening there...

Flashing a kernel shouldn't have done this. Sounds like you either flashed a firmware package that included modem files for a different carrier, or accidentally flashed a different modem, which isn't for your carrier.
Do you know what other carriers are compatible with giffgaff?
Is your firmware carrier branded? I would just flash the latest available firmware for your carrier if it is branded, or if not branded, KI3 or newer from the unbranded thread.
Carrier branded firmware thread is here.
Unbranded firmware thread is here.

It's a little late for that. His problem now is not getting root, but getting his phone working again. I suspect he'll have no choice but to flash SOMETHING to get it functioning again.
I have used odin 1.85
then I rooted with this
CF-Root-SGS2_XW_XEN_KJ3-v5.0-CWM5
I have not done anything else
and I have no signal inside my house
when I go outside I have signal, but is not the sim card, and was working before
this is doing my head in
my carrier is giffgaff
the phone is unlocked and giffgaff runs on O2
You want to set up network .
Use the GiffGaff Tools/Apn app from the market or Giffgaff forum.
Giffgaff will work as O2 PAYG if not set .
You say Mobile wireless do you mean WiFi if so nothing to do with GiffGaff try flash a different modem .
Root should not have caused a problem .
Are you sure you have a i9100 .
and I have no signal inside my house
when I go outside I have signal,
That is simply the network your house is blocking the O2 signal .
you can check your nearest O2 base station

You have a choice
One flash a modem from the modem thread .
Two flash full original stock rom from stock rom thread that will remove root .
Three ask the network is their work on the local transmitter .
Four ask the network to move the transmitter to your kitchen .

Type *#1234# into the phone pad and what is shown against PHONE is your modem number.
As the previous poster suggested I suspect that you have inadvertently changed your modem. I am on Giffgaff with the original O2 firmware on the phone. The modem for this is XXKI4. I understand that the previous modem was XXKI3.
You can download one or both of these modems from
http://forum.xda-developers.com/showpost.php?p=17967764&postcount=5
Please read carefully what it says. i.e. The zip files are intended to be flashed from your internal or external sd card using clockworkmod (CWM) recovery (you have this as you rooted a CWM kernel) and should NOT be flashed using ODIN. If you want to use ODIN then you can extract the modem.bin file from the zip and flash that from the PHONE section of ODIN.
Hope this is of some help.

When I search networks I do get O2 in the list. You wont get Giffgaff as it's not a network but uses O2's.
It may be that for some reason O2 are putting out a weak signal in your area. If your phone is unlocked have you tried sims from other networks to see if you get the same drop off between inside & outside the house. If you do then it would suggest it's the phone (hardware or firmware) but if you don't or the drop off is much smaller then it might just be an O2 signal problem. If you know someone who has an actual 02 sim then perhaps you could try that as well.
I know is not the Sim card, as my gf uses giffgaff as well and I tried on her HTC hero, and has 3 bars, works fine.
I just don't understand why when I rooted the phone the phone network coverage inside my house went to nil, and when I get outside my house and around town I have full bars and 3G is working, I only able to use my WIFI inside my house and Bluetooth.
which is a Pain in where the sun don't shine, because how am I spose to receive calls or call anyone in the comfort of my Home, impossible so people will be thinking that I'm ignoring them, or think I'm rude.
I will try other sim cards and see if that will be the problem.
thank you

I've just noticed that you've put down your CSC as I9100oxaki3. Is this correct? Because I think OXA is a country code for Poland. If it is then perhaps you flashed a firmware intended for Poland. I don't known whether this difference in CSC setting would affect your signal. I'd always thought that the call side of things was handled by the modem and the XXKI4 modem is definitely UK compatible. I may be wrong though.
If nothing else is working then perhaps you could try flashing a firmware with a CSC that is UK specific, includes the UK or is generic European. Post #2 has a link to available firmwares.
I am not sure what suggest then. When i rooted my phone first thing i read was to backup efs using ktool which can be downloaded from market. Then i used cwm manager to backup stock rom. Check in your sd card if have efs folder if yes download ktool and use an option to backup efs and restore using the tool it will ask you if you want to restore by .tar method choose that. It all depends if your phone has efs folder and files init.

As a relatively small network GiffGaff may not be in older or even newer CSC network lists /
Use GiffGaff APN tool .
OXA is Poland
You do not need a CSC to use the phone GiffGaff settings either manually or via the GiffGaff tool

but i am having some problems with the network (have read many threads, but no fix so far)
so, the phone was 2.3.3 version
i flashed via odin stock roms to 2.3.5/6 version
but - no mobile network, changed different roms and on the KI3 i get 2-3 days using the mobile network, and then it loses the network...
any ideas what i can do?
FIXED
Try flashing different modems until you find one that works well for you. There are a ton of threads on here which have links to modem downloads (and many of them are hosted on sites that still work), search for them.

Has your ime changed?
Does this only happen with your sgs2 or does it happen if your sim is in another phone?
Are your apn settings correct?
Sent from my GT-I9100 using XDA App
IMEI is same, no change
the APN settings are fine
the sim card works perfect with other phones, that's why i think the problem is in the phone
will try with other sim card in same phone and will post result. while waiting suggestions
What model do you have? Check on the sticker under the battery. Checking in settings doesn't show the true model. Eg, I have an I9100T but in settings it shows as the I9100 because I use a I9100 rom. I get crap reception on all roms until I flash an I9100T modem.
Sent from my GT-I9100T
it's a gt i9100
so same as in settings
still no other sim card to check
did you try the kg9? in which modem you were in 2.3.3? did you try to return the same? if it does not work I think it's best to bring your phone in for repair
i think no, so i will give it a try
* i am in france btw - do you use the same modem?
with my andy rom i'm in LPB modem and it work very fine but before, i was in ki4 or kg9 and i don't have problem with it
So FIXED
obviously it wasn't a modem problem, but sim card - wasn't working with no matter what sim card. So i did few times the hard factory reset and used again Helroz application from the market, and on the 3rd time, it worked.
10x for the help and the advices guys
what leaves as a question is : am i going to be able to flash custom roms, and what is changed after the use of Helroz application, so i can do backups?
