Hi folks, I have a 5830v, (5830i rebranded for Vodafone Australia)
I had been running ace-i-sure rom, but flashed back to stock via odin, to have a
fairly simple and foolproof setup for my luddite girlfriend. All of that went fine,
but after rooting with update.zip the phone is unable to access the network, giving
a "mobile network is unavailable" error.
Searching around, it seems the usual cause is a missing IMEI, but the IMEI seems
to still be there, verified through *#*#4636#*#*
Running unroot.zip removes root access, but still doesn't let the phone access the network.
So far only way I've found to restore the access is to reflash with odin.
I have rooted the phone before using update.zip, and had no issues at all, so I'm not
sure what's causing it this time around, or how to fix it.
Anyone have any ideas? Thanks in advance
Edit - seemed to work on the 4th attempt :S

Hey guys,
I ran the Suckit Verizon boot unlocker exploit, and it was successful. At which point I used TW Recovery to flash Android Revolution HD 8.0 (N7100 ROM). My phone wouldn't connect to the Verizon network, saying I did not insert the proper SIM card. I found this strange, but realized Verizon locks their network to international phones. I then used the Verizon Toolkit to flash back to stock recovery and ROM. After doing so, I still had no luck in activating my phone.
I called tech support (now having stock everything) and they told me it was likely my SIM card. After spending 2 hours at the store today, it is clearly not the SIM card. They have no idea what the problem is...
When I flashed Android Revolution, I wiped my efs. Could that be the problem? Is it possible to flash a new EFS or COM3? I have no clue how to reactivate to the network..
Anyone have this problem? I did a search on both Suckit Verizon and the Verizon toolkit thread and no one appeared to suffer from this. Please help! Any solutions are greatly appreciated. Thanks in advance. Will update if those guys at Verizon come through.
Definitely has to do with wiping my EFS and not saving it. Under Settings > About > Status IMEI is unknown as well as all other carrier info.
Can someone send me their EFS or is their a way to restore the EFS without having backed it up?
Flash the full Odin restore image and that should fix the problem. Note, it will wipe your data and re-lock the bootloader, but it should at least connect to the network again.
If the stock Odin doesn't work since your imei is unknown this may be what you need, but listen to imnuts first

Flashed stock rom. No luck. Now I have to root back, as one of the prerequisites is being rooted. Will get back.
I kind of had this same problem right after I rooted/unlocked and before flashing any ROMs. I was getting signal bars but kept getting a cannot connect to network error every time I tried to place a call. I called customer service and they "reset" my account, whatever that means but it still didn't work. Started driving to the Verizon store and decided to try one last factory reset and it started working! An IT guy at my work said the account reset plus factory reset got my device sync'd with Verizon signal again. Don't know if what he said is true...don't know why it worked...don't know if this will help you but I thought I would share my experience. I know what you are going through so good luck!

I had almost the same problem using MIUI for AT&T's variant. I was able to get most functionality back by accessing the hidden menu and doing the ##RTN#, but still cannot get 4G LTE back. Maybe this will help you get started too.

According to the OP instructions - which I have done entirely correct. Put phone in Debugging, Went to Qualcomm settings in Hidden menu and set to "RMNET + DM + MODEM" , connected to the proper COM port, clicked the READ on top, however when I go to click the second read to populate the information -> Says cannot set device into DM mode.
The instructions and accompanied video do not reference having to place the device into DM mode at all. The fact that I am getting this error message is also a unique problem.
Anyone know what this could mean or how to fix it? Could it be due to the USB Qualcomm settings not "taking or shifting", although it does confirm that I changed by saying "Saved"
Also, can Verizon Wireless sync my IMEI in store if I bring the original box with the IMEI barcode on it ? Can they flash / scan it to the phone?
anybody?
Can Verizon Wireless sync my IMEI in store if I bring the original box with the IMEI barcode on it ? Can they flash / scan it to the phone?
I know with a fact that the stores do not carry any flashing software for any smartphones. So there is nothing they can do.

I flashed a custom yesterday and phone started up good and everything worked except I cant connect to my network provider. I tried resetting the network settings and everything, I restored back to my stock rom and still cant connect to my network, IMIE number is there and everything. Dont know if I screwed the SIM card up when i flashed the rom or not but its getting frustrating....anyone with help would be awesome...thanks
Did you try to start "from scratch" with ODIN ? This is the only to make sure the issue is hardware/firmware related.
If yes, then maybe you are a victim of the bug described here: http://forum.xda-developers.com/showthread.php?t=1852255
Also any info on the ROMs before/after would help.
Hi I'm looking for help with my i9300. I had an aborted root, the phone froze during root and eventually I had to restart, I was able to re-install the stock ROM and the phone seems to work fine, apart from one major problem: It won't recognise any mobile networks. The phone won't recognise my network (3), or simcards from any other network. I have re-entered the APN information manually, but this has made no difference.
All other aspects of the device work fine, wifi, apps etc.
I'd appreciate any advice on steps I can take to resolve this.
I have obviously tried standard stuff such as full factory reset.
The phone still displays coverage bars as if it was connected to a network, but when I try to dial out or send messages I get an error message "unable to register on network"
Check the imei number matches the one under the battery, if it has changed then you have major problems without a backup of the efs partition. Search and read for hundreds of similar threads, there is a sticky in the general forum.
So.... I bought a TMO Tab 10.1 and being a habitual rom flasher and tweaker I proceded to root and flash xxxx onto it the first day. Life was wonderful and everything worked fine.
But..... being a flash addict I couldn't leave well enough alone. I wanted more. I found this thread ( http://forum.xda-developers.com/showthread.php?t=1336659 ) and proceeded to attempt the appearingly simple task of unlocking the subsidy lock so I could throw my ATT sim in the tablet if I wanted to. Things went terribly wrong art this point.
I followed the instructions step by step and yet now I have no cellular connection at all. Everything else seems to be working fine though.
What I need from the geniuses here on XDA is some guidance on how to restore my cellular ability. I did copy over the EFS folder to another location so I do have an original back up, but I am unsure as to how that is supposed to help? I tried copying and replacing the hacked/ modified EFS folder with the original folder after I lost connection but it did not restore my connection.
What am I missing? Should I flash a new modem? Should I just Odin back to stock and start over? Will that recover my original EFS settings or am I hosed?
Any ideas or help would be appreciated immensely.
So in case anyone searches for this..... I used Odin and flashed back to the stock TMO 4.04 firmware that i got from sammobile.com. I got my signal bars back and seem to have a connection of some kind as my signal bars go up and down. I also threw in an ATT sim card and it didnt reject it or ask for a unlock code.
However.. and this is a big problem, I have that stupid generic IMEI number still. You know, the one that starts 004999 so now I have to fix that. TMO hates tablets with a generic IMEI number and doesnt seem to let them on their network. I do have a backup of my efs folder so it wont be impossible, just a hassle.
Before I start with the issue, let me begin with some basic information: This is in regards to my Samsung Galaxy S5 SM-G900T (T-mobile), running Lollipop 5.1.1, FOG6 build, DOB1 baseband, rooted, deodexed, but otherwise stock.
My problem: Today I flashed a rom via Mobile Odin Pro and soft-bricked my device. After a lot of hair pulling and screaming at my phone and computer, I finally got my phone up and running again. After trying many different solutions, I eventually tried re-flashing TWRP through Odin (recovery initially would not boot, hence the soft-brick), which succeeded, and then recovered my phone by restoring from a previous backup.
This got my phone up and running again, but once it boot, I had no service. I first checked my APN settings, but was presented with a message stating, "Unable to view the access point name settings. Access is restricted for the current user profile." I tried adding a new APN, but once I added it, it did not appear in the APN list, which continued to only display the above message. I then tried to "Search now" for Network Operators, but nothing was found. So next I checked my IMEI through "About Device", and discovered it was set to "Unknown". Checking the IMEI through the dialer (*#06#) lists the IMEI as "null / null".
I have searched high and low and tried everything I could find to fix this. I tried restoring my TWRP EFS backup to no effect. I also tried flashing the modem through Odin, as well as restoring my TWRP modem backup. I tried using an Xposed app to manually set the IMEI back to its original value (I happen to have my phone's original IMEI number written down from when I SIM unlocked my device), but while this updated the IMEI displayed in the dialer (through *#06#), it did not change the value in "About Device" and did not restore my service.
The last solution I tried (found here: http://www.technobezz.com/restore-galaxy-null-imei-and-fix-not-registered-on-network/) involves me using the dialer to enter Service Mode to make some changes; however, while dialing *#197328640# did open the Service Mode menu, the menu was totally blank.
Please help! Given the current state of my phone, I cannot make or receive calls or texts or do anything else requiring a mobile connection. I have looked everywhere and I don't know what else to try :crying: :crying:
Assistance in this matter would be greatly appreciated, as until I am able to fix this, I don't have a functional phone
Any suggestions?
