[Q] S i9000 unable to connect to network

Hi, I'm hoping you can help. Total noob so please bear with me.
I got a Si9000, it says it is unlocked.
When putting in sim card I got data network not available error.
Installed S1_Odin_20100512.pit
In PDA option I put in code_i9000XXJVS_CL565837_REV03_USER_LOW_SHIP.tar
For phone option I put in modem_i9000XXJVS_REV_00_CL1059471.tar
For CSC option I put in GT-i9000-CSC-MULTI-OXAJVS.tar
After I was told to type in *2767*3855# to reset phone.
Phone has been updated to 2.3.5, but now getting not able to connect to network error. It says mobile network unavailable. Any Ideas?
Thanks

have you checked that you have the correct settings for the network you want to use and also check that you have a valid IMEI number

Thanks for replying
Yes, the phone is shows the network, but when you try to select it, it says unable to connect.
I just checked there, and the IMEI number is valid

The files are in the right place, so nothing wrong there. Is wifi working?

Yep, but wifi is the only thing thats working. No data or mobile network, no GPRS either

Which network are you with and what settings do you have in APN ?
Would recommend ...flashing Rom and Re-Rooting*

I am wondering if it's just something in the connection settings. When I went to Japan last year I had to fiddle with something in the settings before I could pick up signals. It was in mobile networks. I think you can select cdma or something like that.

Im with Go Conquer in Ireland, actually brought the phone to a shop to be unlocked, as it was Vodafone, but they said it already was unlocked. They have their settings up on their website so I have entered them.
I'm going to try putting it back to its original settings again, and rooting it again, do you think that might be it? Ill also try the cdma settings.
Thanks to you both

Follow my Guide below to flash Rom and then Root it
Why did you go to a shop to unlocked it ...theres apps on here free??

Did you manage to get it right again? I'm having the same issue as you do. I did a factory reset with cwm and now when I enter the sim card it doesnt connect to network or 3g. Wifi does work. I am on original rom 2.3.5 and I dont know what to do. I tried a other sim and that didnt work either. Please advice. Thank you.

Are you sure to have flashed ROM with proper CSC bandwidth for the region where you live?

Hi,
Thank you all for replying! For some unknown reason the phone works. I left it a day off and then I powered it up again and it worked. So I dont know how but thank you guys for replying!
Grtz,

How should I downgrade or enable GSM/WCDMA option on Sprint LG G4 LS991?

Hey, guys this is my first post here on XDA so please apologize me for any inconvenience.
I bought LG G4 Sprint i.e., LS991 yesterday from someone else I don't have contact with him now. The sim card which works on 3G was working fine when I bought it. But, then I tried to go in settings and then to mobile network and I opened the list of network bands and unfortunately I was only able to find only two option that are 1. CDMA/LTE and 2. CDMA.
I was forced to select one from it and boom no signals at all and status says searching for service. Where is the GSM option? I'm sure that this phone is already unlocked and it is from Sprint.
Also, I'm on the latest software version that is LS991ZVD. Can I go back to ZV6 International ROM or will it brick my device?!

Bro, I found this on this site:
1. go to settings and add new APN manually (fill the values according to your carrier).
2. in the APN type input "default,dun,fota".
3 .save.
4. Restart phone and you are good to go.
Works like a charm... The signal loss thing happened to me too. Don't select either option after you fix it. Go to backup and reset and reset your network settings. I think this is what I did to solve the problem.

Phone can not register in GSM network even after SIM unlock (QPST Backup needed)

Hello! I need some help with my HTC One M8 Sprint.
Im from Russia, phone work well about 2 years with full gsm network support.
After turn off due batery disharge SIM Locked again. I flash Sense rom and make sim unlock but my phone unable to conect to the my operator network.
I read here that sometimes GSM bands can be reset. I install QPST, made a backup of NVRAM and folow this instruction https://forum.xda-developers.com/sprint-htc-one-m8/general/enabling-3g-umts-countries-t2847461.
After this my phone start to see Russian mobile operators, but can not register on them.
I tried chage my SIM card and tried SIM card of another operator, dont work. Just cant register in network.
I think that in addition to the band something else reset in the radio module firmware.
I put the phone in the service center, but the diagnostic for mechanical damage did not give any results, everything is fine.
I attach all avaible info from DFS app and fastboot and proof that my phone scaning networks, maybe someone can help.
If anyone has a backup of NVRAM, please, chare it with me so i can compare parameters.

OK I will try to help you, I'm currently busy. For now hide the picture with your imei.
BTW which ROM are you using?

Ok, I started from the beginning.
Flash 4.25.651.14 firmware.
Install 4.25.651.14 RUU.
In this tread some guy said that he cannot connect to the network on MM RUU and 4.25.651.14 RUU helped him.
Make Factory Reset in fastboot and radio reset through the command ##786#.
Then I make SIM Unlock with this method.
Intall InserctCoin ROM that figure in instruction and go on. SIM unlocked sucessful and GSM operators became available when scanning.
But still can not connect to the network

Maybe I'am doing something wrong? Can you please post your HBOOT and Radio version?
And where did you find that file?
Thanks you for posting that, it restore my hope

No Service/Signal with Android Pie

So I bought my XZ1C in the US, flashed Pie (tried SG, TH, FR) with newflasher/flashtool, since the official US Pie is not out yet, all files except Simlock.ta. All the firmwares showed full signal some time (3~5 minutes, give or take) after boot on, but none of them were able to have data access, and phone calls cannot be made. Xperia Companion doesn't fix anything. Rebooting doesn't fix anything. Same if I take out my sim and replug in, same if I choose WCDMA/GSM or GSM only, same if I reset network settings, and same if I flash the baseband files + OEM.ta from US 47.1.A.16.20. When I go in to the testing (*#*#4636#*#* if I recall correctly), all numbers are 0, indicating no issues with the sim card itself. IMEI is showing up correctly, and the phone even recognizes my carrier. If I rollback to Oreo, everything just works fine, whether it's US, HK, FR, DE, or whatever. It's been really depressing, and I appreciate if anyone could help me out with what is happening here. BTW, my carrier is CTExcel, based on T-Mobile in the US. Thanks.

Does you've try a factory reset after upgrade to Pie?

Have you checked the APN settings? maybe your vesrion is failing to download the correct settings.
Look up what they should be for CTExcel, then apply them manually.

Well, I don't think that's necessary cuz I flashed everything using newflasher/flashtool, including reset.

I'll give it a shot, but I doubt it's because of that. My carrier never required APN settings on iOS or Android Oreo; all it has in APN is something called "alpha" on my iPhone 5s.

I haven't the problem at all. which are reported.... OK... first at all, I have received a loop of reboot during the Sony logo.. After that I press power and Volume up for a few seconds... the phone vibrate some times (normally its means factory reset). After that it was started and I'm at the beginning...

Ok, I used my home-country SIM card, and enabled roaming, it worked, with AT&T network connected. Changing the APN to my US carrier's didn't solve the problem, however, so I suppose I shall just contact my carrier then. Thanks, bro.

I rely heavily on internet, and lose my not so many marbles left when without it, I feel your pain.
From what I am seeing trying to look into your problem, you have done all that is suggested, other than a service centre visit
Hopefully someone who has suffered but resolved this will comment and share the steps for you :fingers-crossed:

waiting for your comment brother

Have you check your APN settings?
Replaced your SIM card? (It might work on other phones but not on yours either to not sitting properly or something else. So try replacing it.)
Take your sim card out and try this.
Do a factory reset and flash firmware with CSC file (not home-CSC file, backup first. )
Let phone boot without sim card first.

You're not going to get CDMA to work on the F version of the phone as far as I know you can only use GSM that's why nothing that's being suggested is working. You need to get a GSM carrier sim card.

Ok i am trying to understand something.
Your device is SM-N950F/DS.
You are in india.
The phone can't connect to 4g/Lte after the security update. 2G and wifi is ok.
Before the update 4g/lte is fine.
You tried your simcard on other phones is able to connect to 4g/lte.
Is this correct?
May i ask how did you update to the latest firmware? ota, odin or smart switch?
