[Q] Lost 3G service

Somehow while Rooting and Updating I lost all 3g service on my Verizon Tab. This is a replacement Tabe sent to me by Verizon. When I tried to restore the info from my prior Tab this one came up "No Service" I tried going back to stock, all the previous backups still on my SD card. Nothing works. Anyone know what I need to do to get the 3g back......
Oh ya
The baseband version is unknown

http://forum.xda-developers.com/showthread.php?t=955342
You need these I had a similar situation, but these are all the files you need including the modem for 3g

I followed those instructions when I tried to go back to stock. Do I just need to add the modem file in the modem spot in Heimdal or do I need to put all the original file back as well?

i did a complete reload when i did mine using heimdall
Hold down power and volume down to get into download mode.
factoryfs.rfs in factoryFS
zimage in Kernel(zimage) and recovery
this is important read carefully before selecting
there are 2 param. files you want the param. lfs it goes in param.lfs slot
cache in cache
and modem in modem
Those are the only files you will need. It worked from me I have been working on themeing the tab using the deodexed roms posted in development so i have really got stuck before and these have saved me everytime. Hoping to post and accurate battery mod ported from sbrissen over on the fasc forum he has been helping me on it and i think i have a stable version
hope this helps

No luck, tried flashing the files twice no change. Still no 3g and the baseband still says unknown.

you said after you restored from your previous tab, What happened to the previous one? the same thing? and how did it get that way?

On the previous tab I was running KhasMek's K-leanMod v3’s Rom and KhasMek Voodoo Plus v5 Now with Full Voodoo CwM Kernel. I wanted to go back to stock so I could get the latest Verizon update. I wanted the Bluetooth HID access. After I converted back to stock I was unable to load the update. It would download but not install. The Verizon tech was unable to help me so they sent me a new one. I realized that I forgot to disable the lag fix before I went back to stock.
This time I Rooted (using super one step root), installed Titanium backup and installed my backed up apps. When I rebooted I lost the 3g service.

did you remove root and tb b4 you tryed flashing the stock files? Also did you have voodoo active if so deactivate before flashing back to stock.

Bell Stock FW
I've made a copy of my Bell Galaxy Tab FW using the Roto Backup technique which you're welcome to try. I haven't try restoring it to my device yet as I *just* got it and am still a little hesitant - so use at your own risk - I will assume no liability for what it does to your device. The image is version JJ7, rooted using z4root (you should just be able to use the same to unroot it), and unlocked using the hex edit technique (http://forum.xda-developers.com/showthread.php?t=843323 - or specifically, I changed byte 0x181469 from 01 to 00 using a hex editor - so you can just reverse this to lock it again)
I would also consider the alternative of restoring to the JJ3 "Provider Samsung P1000 Firmwares" available on samfirmware.com. After that, upgrade to the most current via Kies. I have not tried this and assume no liability for what this does to your device either.
Let me know if you'd like my Bell image and I'll send you a link to it.

Hi smd2008,
Would you please provide a download link for the 'Bell stock rom'? I need to revert back to stock. Much appreciated!

Hi do you mind if you please send me that bell firmware please thanks

Hi, I'd love to get my hands on a copy of the Bell stock firmware...
warranty issues.... please help!

Roto Backup of Bell Stock ROM
Hi smd2008 or any one,
Could you share your experience with the Roto backup of your Bell stock Rom. I have just tried to do a Roto backup for my Bell SGT ( UGJJ7 ) . When it came to adb pull commands, system returned an error saying the file was not exist.
I have tried both Z4Root and SuperOneClick 1.9.5 to root but both cases showing the same error. I had set the SGT USB to Debugging mode and mounted as R/W with Root Explorer. I used the Command mode in PC then followed the Roto backup scripts. I used the ADB files attached with SuperOneClick download. Occasionally, the connection of the SGT to PC might lost when I entered the -dd command for dbdata.rfs. But I managed to completed all the -dd and tar commands after re-starting the PC. It looks like the files were created but just couldn't find them.
Could any one advise how to correct the problem? Thanks.

Found the cause of problem. It was due to SDcard not mounted.
Could someone please inform how to get the SDcard mounted when using the command mode in PC to do Roto backup.

bell stock firmware
hi
i was wondering if i could get a copy of the firmware as well, for warranty purposes i need to flash my tab back to stock.
thank you

Any hopes to get the stock rom for Bell Froyo?

Did you reboot the phone when you finished modifying the nv_data.bin?

I believe the update NV_data.bat has a spelling error:
adb shell su -c "busybox cp /sdacard/nv_data.bin /efs/nv_data.bin"
After a few well timed screenshots I figured out this was my solution:
I changed incorrect line to sdcard, and moved all the files pulled from phone (including corrected NV_data.bin) from the efs folder to the main folder containing the update NV_data.bat. It wasn't finding them.
Now the NV_data.bin i pull from the phone has the correct code!
Will update in a moment to see if KIES sees it as a rogers FW again.

1.Flash to Stock with Odin3 1.81 with 2.1 ROM from SGH-I896 wiki here:
http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S/SGH-I896
2. Flash 2.2 with same method.
3. Do this to fix CRC http://forum.xda-developers.com/showpost.php?p=17461697&postcount=6
4. Do this http://forum.xda-developers.com/showpost.php?p=17835946&postcount=11 ***with my changes mentioned above***
This is what worked for me and I'm updating through Kies right now.

Do i just right click and select edit and modify it ?

i finally got it
i edited the error in the script but it still was not working
so i manually copied over the nv_data.bin and nv_data.bin md5 files to the root of my phone and it worked.
so step by step i went:
stock 2.1 toronto
to stock 2.2
did the csc upgrade with odin using no pit and no repartition
rooted the phone
put phone in debug mode
downloaded the efs using efs backup
edited it using hexedit
edited the update nv_data program so it says sdcard instead of sdacard
turned of debug went into mass storage
copied nv_data.bin and nv_data.bin md5 to the root of my phone
went into debug mode
ran update nv_data
and now kies is updating
a big thank you to Nick0703 and arlichv you guys are awesome thnx for taking time out of your lives to help me

Good show! I forgot to mention abour re-rooting so you can run the NV_data.bin fixes.
Superoneclick worked fine for me.
Whatta bloody process to get back to a REAL stock FW.

Just wanted to mention that JL1 is stock Rogers 2.2 firmware and not AT&T.

Any talk of AT&T here refers to the left over product code from a previous AT&T based custom rom and not the actual FW itself.

Signal Issues

Hi, I am new to xda and i'm also quite new to the flashing process. I have a captivate i896 and successfully flashed a rom on to my phone. However after doing so the phone is unable to connect to my mobile carrier. I have also tried to install a modem from the stickied thread how ever it gives me an error::
cwm 3.0.zip error
i'm going to try to flash the helly bean rom in hopes of getting that fixed.
also in the about phone section it says baseband is unknown... ive googled that and it said my IMEI is corrupted or something or other.

It sounds like your /efs folder is messed up. There's a thread in the Development section that goes through steps on how to restore you /efs and IMEI all on the phone.

I'm very lost right now, still cant seem to install any modems on and i checked in the EFS folder, there isn't anything

Please check first if your IMEI shows up in the about phone and that it is the same as the one on the inside of your device. For modems there are diffrent ones depending on what ROM you have flashed so give us that info please. Lastly if your IMEI is diffrent give this a try http://www.xda-developers.com/andro...s-ii-and-other-samsung-devices-in-nine-steps/, i have not used this my self but might be what you need

IMEI shows up as 'unknown'. I flashed the latest cm10 and used the modem KG3 under I9000.
Also, I'm in Toronto, so I'm running the i896 captivate.
i rooted and installed CWM by following the steps in this link http://forum.xda-developers.com/showthread.php?t=1350266
then after when i installed cm10 the IMEI dispapeared

sorry bump. but i think the problem is that i an unable to install the modem.. if anyone can please guide me to install a modem that would be very nice. ive tried to install it through CWM but it gives me a status 0 error everytime i try

If your IMEI shows unknown in the settings menu then it has nothing to do with whether the modem will flash or not. It means your efs folder was wiped. Now you could in fact be without a modem too but you need to fix the IMEI first.
Now with updating to CM10 theres a good chance it made a backup of this for you. Look on your internal SD card for a folder simply labeled backup. If so look in it and see what it has. Hopefully it will contain another folder labeled efs. If thats the case too then all you need to do is get something like root explorer or ghost commander and copy the contents of that folder into /efs in your system.
That will fix the IMEI issue.
As far as modems go you will only be able to flash these... http://soggycashew.weebly.com/cm7miui--ics-modems.html All the rest will give errors when you try to flash.

[RESOLVED] Help restoring /efs folder

Greetings!
I apologize if there has been a similar thread, but I couldn't find anything that worked, so here I go:
I flashed to the official XWJW1 firmware (which I got from here: http://forum.xda-developers.com/showthread.php?t=1102881) successfully, I then proceeded to root it by flashing Semaphore 2.7.4, again successfully. I then booted into CWM recovery and flashed Slim-I9000-4.2.2.build.3-OFFICIAL.zip. The first time, the phone rebooted almost immediately and got stuck at the boot screen, which I assume was because it installed the new Semaphore kernel only, so I removed the battery, went back into recovery mode (this time it was indeed the new version of CWM) and reflashed the ROM successfully. I installed Slim_Gapps.4.2.2.build.8.zip as well and booted into SlimBean. All is working great apart from the "minor" problem of no mobile network. I went in the settings > mobile networks > network operators and got "Error while searching for networks". I went to check the information under About Phone and saw this:
Baseband version unknown
I read it could be due to messed up /efs folder, so I reflashed the official XWJW1 rom (with working network and correct baseband version), rooted it and copied the /efs folder (using ES File Explorer and Superuser). I installed the SlimBean rom again (still no network and no baseband version info) and tried replacing the /efs folder: first with the AROMA file manager from within the recovery mode, then with ES file manager, then with Android Terminal Emulator - NONE worked. I tried deleting the entire folder and then copying the backed up one, I can't delete it (even though I have superuser permissions). For example ES FM gives "error code 39" when trying to delete the folder and it either deletes all files from inside (apart from Lost+Found folder) or only some of the files. Same with AROMA. I checked that /efs is mounted rw... (I'm not even sure if I should try to alter it while it's mounted and the phone is running, but this was one of the ways I read about while searching. When I enter CWM recovery, it does not appear to be mounted and thus is empty.. so I assume whatever I paste in there will get wiped once it's mounted at boot)
Any idea how to restore the folder from the stock firmware or how to get a working mobile network?
Model number: GT-I9000
Android version: 4.2.2
Baseband version: Unknown
Kernel version: 3.0.71-Semaphore_JB_2.9.18s

Try flashing "stepwise", ie.
2.3.6 ->CM9 -> Slim Bean.
This ensures that your IMEI is kept. When you flash CM9, let it boot completely first, then reboot into recovery and flash Slim.

Thank you! That indeed worked! One question: when I installed CM9 the firmware changed to XXJVT (and this is now the one shown under baseband version in SlimBean). Is there any major difference between XWJW1 and XXJVT, does it matter at all?

Modems do differ, mostly in terms of region (most modems are localised for certain countries). The differences between XXJVT and XWJW1 I have no idea about.
For most people it doesn't really matter, XXJVT is fine for them. Changing modems is only really something that you do either to save battery (some modems are better at battery than others), change for region (say XXJVT doesn't work too well in your region) or just to test other modems.

I'm having a similar issue now too. Going from jw6 to cm10.2 and lost my imei. Tried the advice above. jw6 - cm9.1 (imei fine) - cm10.1.2 and get the imei missing message. Maybe I'm gonna just have to stick with cm9. In the end it's just a backup phone for my kids but I want nova on it.

Hmmm.
Try
JW6 -> CM9 (If your IMEI was fine, then I don't really see why there's a problem...)
Then CM9 -> CM10 or CM10.1.0 (as another intermediate step, to see if your IMEI survives)
If your IMEI is fine, then flash 10.1.2
Odd though, the only time I've had IMEI loss going from CM9 to Jelly Bean was because I didn't let CM9 boot up properly first... So try to flash CM10.1.2 straight from CM9 and see if you run into the same problem again
