DISCLAIMER: I AM NOT RESPONSIBLE FOR YOUR ACTIONS. IF YOU BRICK OR DAMAGE YOUR DEVICE IN SOME WAY, IT IS YOUR RESPONSIBILITY. THERE ARE SOME STEPS THAT MIGHT NOT BE LEGAL IN SOME COUNTRIES (CHANGING IMEI NUMBERS), AND I WILL NOT BE HELD RESPONSIBLE FOR THAT EITHER. EVERYTHING YOU DO WITH YOUR DEVICE IS YOUR OWN RESPONSIBILITY AND IF YOU FOLLOW ALL THESE STEPS YOU ARE AGREEING TO THAT. THIS TUTORIAL IS DONE FOR EDUCATIONAL PURPOSES.
Thanks to clubtech, rotohammer, koush, ayman07 and everyone in xda that has worked hard to make this possible. I did not come up with any of this, I only gathered it all from different sources and smashed it all together in an easy-to-read guide. Credit is due to all of those listed above, if I missed anyone please do let me know and I'll gladly add you here.
You will need
- P1000XWJJ4 firmware (pass: samfirmware.com)
- P1000XXJK5 firmware (pass: samfirmware.com)
- Odin 1.3
- Koush's zImage for T-Mobile Galaxy Tab
- flash_image
- I900AOJP3.bin Modem from HERE
1) Put you tab into download mode (Turn it off, when it's off, Press VolDown+Power until you see a yellow android and it says downloading...) (WARNING: All your data will be lost in the next step! Everything, INCLUDING the internal memory! Make sure to back everything up to your computer!)
2) Use Odin: Flash P1000XWJJ4 (PDA button) with P1_add_hidden.pit and make sure "Re-partition" is SELECTED, press Start and wait for it to finish. The device will reboot and it will turn on again, probably in russian.
3) Turn it off and put it on download mode again.
4) Use Odin: Press the reset button, then make sure "Re-partition" is UNSELECTED and there's NO PIT file, then flash P1000XXJK5 under "PDA".
5) The device will reboot with the latest euro firmware in english. The modem will probably be undetected, the device will be working kinda crazy (It might be slow and whenever you use something that uses the vibrator it'll get worse, the vibrator won't probably work, don't worry about this, it will be fixed in the next few steps)
6) Make sure you have flash_image and the tmobile_zImage in hand and issue these commands:
Code:
adb push flash_image /data/local/bin/flash_image
adb push tmobile_zImage /sdcard/
adb shell
su (make sure to select "Allow" when the Superuser dialog pops up on the tab)
chmod 755 /data/local/bin/flash_image
/data/local/bin/flash_image boot /sdcard/tmobile_zImage
sync
exit
7) Now, the kernel should be flashed, a reboot should fix all the weirdness. However, instead of rebooting, turn it off, and put it on download mode again (VolDown+Power)
8) Use Odin: Press reset on Odin, make sure "Re-partition" is UNSELECTED, and on the Phone button, flash the modem I900AOJP3.bin.
11) Wait for it to reboot. At this point, the tab should work fine, and the modem should be detected by the system. However, you won't be able to make calls or use the internet because T-Mobile is blocking data. Now, we need to change the IMEI number (READ DISCLAIMER ABOVE!)
12) Now, we need to backup all the contents in the /efs folder, that way, the IMEI will be corrupted, we want this to happen because T-Mobile is blocking the IMEIs on all T-Mo Galaxy Tabs so that data doesn't work unless you have the right plan/contract (BAD MOVE T-MO! WE DIDN'T EXPECT THAT FROM YOU, AT&T MAYBE, BUT NOT YOU!)
13) Backup the /efs folder (Notice: you must have busybox installed, get busybox installer from the market)
Code:
adb shell
su
busybox tar zcvf /sdcard/efs-backup.tar.gz /efs
busybox cat /dev/block/stl3 > /sdcard/efs_dev-block-stl3.img
exit
back to the shell in your computer, now use these commands to put those files in your computer, and save them somewhere safe.
Code:
adb pull /sdcard/efs-backup.tar.gz .
adb pull /sdcard/efs_dev-block-stl3.img .
14) Delete all contents from /efs and reboot. Easiest way to do it is using root explorer from the market. DO NOT DELETE THE ACTUAL FOLDER, JUST IT'S CONTENTS.
15) Done, you will be able to browse the web, send/receive SMS, and send/receive voice calls. The only issue at this moment is that it will only work on EDGE, 3G is not possible, YET.
Enjoy.

Where exactly? Please link me to the post that makes your T-Mo Tab make calls, using the Euro firmware and vibrator works and the tab doesn't go crazy.
As I said, all the guides I found were missing a few pieces. One was for AT&T Tabs, but I didn't find one that was for T-Mo tabs in a single piece, everything was scattered all around.

Oh ok, didn't notice that also works for T-Mo tabs. Oh well.
Thanks.
Thanks for posting this guide. I followed the instructions and still cannot make phone calls. It seems to dial but the T-Mobile automated voice operator says "The phone you are using does not allow outgoing calls."
I removed all /efs files and rebooted, then verified that the IMEI was corrupt afterwards.
Any ideas? Maybe T-Mobile is blocking the corrupt IMEI number now?
Thanks in advance!
Are you able to use the market ok with your imei corrupted?

I don't think so. Are you using a SIM card with a plan that has phone calls or are you using the same SIM card? Your Tab has a webConnect plan that does not allow phone calls, so you need to put in a SIM card that has data and calling plan.
They are blocking the IMEI for data, as far as I know, so if you use your tab to go online (without using Wifi), and it goes to my.t-mobile.com even if you try to go to xda-developers.com then they are blocking it, but in your case, it's just probably the calling plan.

LS970 EFS Backup/Restore/Repair
Every rooted Optimus G user should backup their EFS partitions!
Thanks goes to interloper, toastcfh and everyone in #lg-optimus-g that helped out.
PM me if interested in my Sprint LGOG LS970 EFS repair service.
Contents
1. Flashable EFS for backing up your EFS partitions and packing them into a new flashable .zip.
2. Commands for backing up/restoring EFS manually with terminal or ADB.
3. Flashable "ZERO EFS" with guide for repairing your EFS. This EFS needs to be reprogrammed but could be used in a "worst case" scenario where you didn't backup your EFS and the phone cannot be replaced by any LG/Sprint warranty.
Backup script/commands also work on the ATT/Telus variants. ZERO EFS zip is ONLY for Sprint LS970 users. ATT/Telus users, if you would like a ZERO EFS, please send me your efsbackup.tar in a private message. It is not suggested to publicly post your EFS file.
Background
You never know when your NV/EFS/PRL/RADIO may stop working. Restoring your WORKING EFS may save the day. A few users in the #lg-optimus-g IRC channel have run into issues and found their phone unusable, myself included. A few users who flashed the test/Korean JB builds found 3g not working.. or calls/text not working. Some users ran into radio issues after PRL writing failures. My own issues was a missing ICCID which resulted in no 4G. Data wipes, reactivations, ##786# resets were not helping. All of the above issues could have been fixed if an EFS backup was made while the phone was still in working order.
m9kefs1 seems to be radio related
m9kefs2 contains your unique phone identifiers: MEID, IMEI, phone number, MSL, data profiles etc
m9kefs3 seems to be blank 00s
Backing up EFS
It's easiest to run the Optimus_G_Create_Flashable_EFS.zip attached to this thread. Run in recovery. Optimus_G_Create_Flashable_EFS.zip creates a flashable zip backup of your EFS in /sdcard/EFS_Backup/(instead of just a .tar).
If you don't like convenience this can also be done manually with adb or terminal with the commands below.. root required.
Code:
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs1 of=/sdcard/m9kefs1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs2 of=/sdcard/m9kefs2.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs3 of=/sdcard/m9kefs3.img
Restoring EFS
To restore your original EFS just boot into recovery and flash the efsbackupflash.zip in your /sdcard/EFS_Backup folder.
If you don't like convenience this can also be done manually with adb or terminal with the commands below. Adjust the "dd if=/sdcard/" command depending on where your backup EFS .img files are located.
Code:
su
dd if=/sdcard/m9kefs1.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs1
dd if=/sdcard/m9kefs2.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs2
dd if=/sdcard/m9kefs3.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs3
Repairing EFS
YOUR EFS IS *NOT* BROKEN IF YOU FLASHED AN AOSP ROM AND NO LONGER HAVE SIGNAL BUT STILL HAVE YOUR MEID AND PRL SAYS "40000"...
GO BACK INTO AOSP ROM > SETTINGS > MORE... > MOBILE NETWORK SETTINGS > CDMA SUBSCRIPTION > SET TO "NV"
YOU SHOULD NOW HAVE A SIGNAL AGAIN... NO EFS REPAIR NEEDED!!
If you have a messed up PRL/Radio/EFS(no signal.. calls/text doesn't work.. no PRL showing.. no 3G) then you should first confirm there are no outages in your area. After confirming no outages you may want to try a factory data reset(settings > backup & reset) or perform a ##786# reset(MSL required). If you are feeling daring you could even try a lgnpst reset which involves installing lgnpst(automated install on IRC suggested) and flashing a stock .tot to your phone while it's in download mode(power off phone > plug phone into USB cable/computer > vol up + vol down + power buttons). If none of the previous suggestions work you could see if Sprint/LG will warranty repair your device.
If NOTHING ABOVE works your final option is to flash a new EFS. Technically you could possibly look through each and every NV item with QXDM and see what's incorrect but that may take forever... so I have included a flashable zip at the bottom of this thread which flashes a fresh LS970 EFS to your device. This EFS is clear of all personal data and any previous phone identifiers. Below are directions on how to reprogram your EFS to the Sprint network after flashing the LS970_ZERO_EFS.zip. I'd rate this as medium-hard difficulty for those that are unfamiliar with how (Sprint)CDMA phones are programmed. For those that have flashed a phone in the past, this ZERO EFS zip just made your day even easier.
The ZERO EFS has a zero'd out SPC/MSL, zero'd out IMEI/MEID, zero'd out MDN/MSID and all data profiles emptied.
NV item 114(NV_FACTORY_INFO_I) has been "anonymized" and no longer identifies to anyones real account.
In recovery, flash LS970_ZERO_EFS.zip then wipe data/cache(factory wipe in TWRP). LS970_ZERO_EFS.zip backs up your current EFS partitions to /sdcard/EFS_Backup and then replaces your EFS with the ZERO EFS.
You will have to manually program your phone to get it working again.
READ EVERYTHING BELOW IF YOU DON'T KNOW WHAT YOU'RE DOING.
After flashing LS970_ZERO_EFS.zip:
For talk/text working - use DFS(www.cdmatool.com) or other known working CDMA tools.
a1. Set LS970 into diag mode.. open the dialer and hit ##3424# . Also make sure phone is set to "Charge only"
b1. Connect phone to DFS and set correct COM port. Use the diag port NOT the serial port.
c1. In DFS send SPC(MSL) to phone using "SPC" button(under the green ports button, top left). SPC = 000000.
d1. On Programming > General tab... Write desired IMEI with DFS. Hit "status" button to make sure it stuck. IMEI = MEID + 1 extra digit.
e1. After writing IMEI.. write the matching MEID. Hit "status" button to make sure it stuck.
f1. On your phone, open dialer and hit ##000000# and program in your MDN/MSID. Hit done. Phone will reboot.
Talk/text will now work!

For 1X/3G working - use DFS
a2. Connect phone to DFS and send SPC using above methods.
b2. In DFS, open the Programming > Data tab and hit the read button.
c2. Set the UID under HDR AN LONG to your [email protected]
d2. Set the Pwd to your 32-char hex password, no spaces between hex bytes. Make sure box is checked next to Pwd!!
e2. In DFS go to the Programming > Mobile IP tab. Hit the blue "Read" button in the lower left.
f2. Set the username(NAI) to the same username you just wrote in step c2... [email protected]
g. Set the AAA Shared Secret password. The same 32-char password used in step d. Make sure box is CHECKED for AAA!!!
h. Set the HA Shared Secret password to: secret . Yes, the word secret. MAke sure the box is UNCHECKED for HA!!!
i. Hit the red "Write Current Profile Settings" button.
j. Back on your phone, open the dialer and press ##3282# and click "Data Profile" then "edit". Enter 000000 for code.
k. Once inside Data Profile menu, set up your Sprint username and password(AAA password).
[email protected] and the AAA password is a 6-char password.
l. Once data profile is written back out of the menu and the phone should reboot.
1X/3G will now work!! [as long as ALL usernames and passwords were written correctly with the 100% correct info!!!]
*Notes*
1. If a ##786# reset is ever done, the 1X/3G data passwords will be wiped and have to be rewritten.
2. Dialer code 3845#*970# > Data -LG menu has a PPP setting. Never set this to Sprint... always leave on "Undetermined"
3. You shouldn't have to do anything for 4G to work.
Now you may say "yeah, that's great... but I don't know my MEID, IMEI, MDN, MSID, 32-char AAA password, Data Profile username... now what?"
Good question.
IMEI - Hopefully your phone isn't TOO messed up and you can still view your IMEI via Settings > About Phone > Phone Identity.
If you can't read it, call Sprint and ask them for it, mention your phone acting up or blah blah. The IMEI is your MEID + 1 extra digit.
MEID - MEID is on your LG OG box. You can also see this by viewing the current phone on your plan using Sprint.com
You want to use the MEID HEX not MEID DEC. If you can only find the DEC you can use online converters to convert MEID DEC to HEX.
MDN - MDN is your phone number. You should know this.
MSID - MSID is sometimes the same as your phone number, but sometimes not. You can view this info in Settings > About Phone > Phone Identity
You can call Sprint to get this info if you can't view it on your phone.
Data Profile username/password - You can get this info by calling Sprint. You may be able to view the username with ##3282# > Data Profile > View
32-char AAA Password - If you are unable to acquire your 32-char AAA password(NV item 466 and 1192), ask Sprint. You may have to speak to some form of advanced tech support.

Re: [GUIDE] Backup/Restore/Repair Your EFS Partition
So if I'm reading this right, for simple minded people like me, make a backup with the backup zip. Then to restore, just follow that paragraph about restoring?
Does this mean that if I mess up my phone as far as reception, I could just use my backup to restore it? This stuff is way beyond me, so I gotta pick your brain.

it doesn't touch the actual modem/baseband... but it backs up your entire EFS/NV. NV items are sort of like Windows Registry... but lower level than the Android filesystem. The PRL is also contained in the EFS.
If you ever go into a hidden menu and set a weird setting which kills 3g... if you write a PRL and it goes wrong and you lose all reception.. if you flash a rom and all of the sudden your MEID is gone(etc etc etc).. then having an EFS backup would help.
Backing it up saves the current state of the EFS. So yes, if you had a working backup and then ran into issues down the road... you could reflash your backup EFS and you'd have a fix(hopefully).
The EFS contains all the unique parts of your phone... MEID, IMEI, Data Profiles, Phone number.. etc etc. Its the one thing that can't be replaced if it gets screwed up. If you don't have a backup and replaced all partitions from someone elses phone you'd have their meid, imei, phone number data profile etc.. instead of your own. This is where the 2nd half of my guide comes in. In the extreme case that you have no EFS backup and you can't get your phone replaced by Sprint/LG.. the ZERO EFS zip + guide can get your phone working again.

I don't know enough about the Korean JB rom to answer that correctly. I do know it fixes the efs issues if you flash back to a Sprint rom after flashing the korean rom.
is the Korean JB rom CDMA or GSM? I'm not even sure it matters.. but if it's also CDMA I'd have a better feeling about it maybe being possible.
could you tell me the exact issues people were facing after flashing and using the Korean JB rom? was it working minus radio? was radio "active" but not working? etc etc.
as long as you make a backup of your working efs first.. you can always restore back to it. I've flashed bad data to both efs partitions just to see how well this worked. my phone had no baseband.. no working radios... flashed my backup.. all working again. :good:

Updated the Optimus_G_Create_Flashable_EFS.zip in the OP
Now creates a flashable EFS backup instead of just a .tar. Just flash the "efsbackupflash.zip" in recovery to restore.
m9kefs1.img, m9kefs2.img and efsbackupflash.zip are stored in /sdcard/EFS_Backup
I suggest remotely backing up the zip somewhere(Dropbox, PC, etc) just in case /sdcard gets erased.

were you able to get the radio working again after it quit on you 10 min later? did you have to flash back to sprint? everything working again?
thank you so much for this. i dont know if this is to much to ask but could somebody possibly make a zip that would restore them for you because i have absolutely no idea on how to use abd or terminal lol

engine95 is correct. the latest backup efs zip extracts your EFS partitions, zips them into a new flashable zip and stores the zip in /sdcard/EFS_Backup.
also in the efs_backup folder are the loose efs partition files... just cause.
The zip creates the back up but from what I read from the guide it says you have to use terminal to restore them

reread, he forgot to add a word
To restore your original EFS just boot into recovery and flash the efsbackupflash.zip in your /sdcard/EFS_Backup folder. OR To manually restore use the commands below. Adjust the "dd if=/sdcard/" command depending on where the backup .img is located.
It's been updated. Autoprime mentioned it about 8 posts up. Updated file in the op.

Hello, this is really weird. In fact, when I insert the SIM to my Note 2 N7100 and turn it on, it allows me to make emergency call, but I cannot use it to make any others and it doesn't show the carrier name (it shows Emergency call only). And when I try to use it to make normal phone calls, it says that I am not registered to a mobile network. I try to factory reset my phone, but the problem remains. I then try to remove the SIM card, and it says that I need to insert a SIM card (that means that it is not a hardware problem since it recognizes the card). I then try to go to the mobile network setting to try to connect to the network manually, it connects me but it shows me a warning which says that the mobile network service is not available (and the Emergency call only label remains). However, I am sure that this is not the problem of the card neither since when I insert the card to my Moto MB860, I can make calls as usual. So, what is the problem ??? It seems to me that the problem happens spontaneously since it works perfectly until yesterday. And all other wireless function works fine including wifi , Bluetooth and GPS and the only thing goes wrong is 3g and 2g.

Carrier: Fido Canada (as you can see)
Thanks.
First of all, check whether you can see the IMEI of the device. If you can see.
1. Contact your network operator and check whether your IMEI is blacklisted or not.
If you cannot see the IMEI
1.Restore the efs and persist backups (if you have one)
2. flash the device again with the modem image (download the firmware of your device from samfirmwares.com, delete everything from the .tar file except modem.bin, and then flash this file to the phone with Odin (you can get Odin and instructions from that site or from here)
2. maybe your nv_data.bin file or /efs directory got corrupted, make a backup of the folder, then simply delete nv_data.bin, it will be recreated for you.
For this, you’ll need root. If you have a root-enabled kernel, you only have to install the Superuser app and Busybox on the phone, download the Android SDK to your PC, install platform-tools in the SDK manager, go to the platform-tools directory and start adb shell.
In the shell, type su, wait for the Superuser prompt to appear on the phone (if it does not appear, open the Superuser app and try executing su again), enable root access for the command. Now go to /efs, copy everything to for example /sdcard/efs, then rm nv_data.bin.
Reflashing the device with a kernel and checking “phone EFS clear” in Odin also works (make sure you made a backup of the EFS folder just in case).
3. you can try changing the CSC: enter *#272*imei# on the phone tab.
Try this . I'm not sure it works. Just give it a try on yourself.
Trying the above mentioned methods could be vulnerable to your phone if it not done properly. So do it carefully. If you have any doubts feel free to ask me or search elsewhere. But, don't blame me for a fully dead phone. I am not at all responsible for any...
Noob 1st post......have had similar problems with koodo CDN
Not gonna give such an in depth suggestion as above.....he's something simple to try.
I live in a dead zone and often my phone ( galaxyAce) will switch to no service. Even after refreshing and selecting network under settings, it says it's connected, but isn't. A simple apk that always fixes the problem for me is Network Signal Booster @ theplaystore

I tried a simple way which is format everything and flash another ROM but the problem remains.

I don't know that we are in the same situation since at home I often got a good signal and this happened to me only since yesterday.

I need to get the firmware first... since I already passed the download quota for today... need to wait until tomorrow...
Mmm... I heard that you mentioned clearing the EFS in your given procedure, but I do not think that I modified that folder... However, about few days ago, since I want to gain better control on the volume on my headphone remotes, I did modify the file called Generic.kl in system/usr/keylayout, but I restore it after since it didn't work. However, I don't think that this modification will trigger something in the efs folder since it has different directory. By the way, I did some research online and they say that the efs contains information about the carrier on the phone, so will there's a greater chance that the problem is caused by the possible modification on the efs than any other factor and will there also something else that possibly trigger the similar effects?

Well I got it working. Now I cannot comment on the exact steps above as I had already applied the other "permanent sim unlock" procedure. I can tell you what I did though.
-I did not remove my sim. I don't think that step is necessary.-confirmed not necessary
-I copied the carrier files to carrier/apps
-I copied the files from etc folder to etc
-I left the apn-conf file from the previous unlock-This is necessary
Reboot
This gave me signal, but no data
-I entered ##DATA# in the dialer
-Hit APN Setting
-Hit menu button, and Reset to Default
BAM... GSM signal shows up, I have data working.
Also confirm the hands free activation didn't appear after the steps above.
Guys can u help me root my phone.

Take a look through your apn-conf file and make sure your APN is listed properly. Make sure you rebooted your phone, it often needs that to pick up APN. If it's there, try resetting to default again in ##3282#. Hope you get it working.

I haven't tested that, but I don't see why that would affect the unlock.

this is the only unlock method that fully worked for me.. sim unlock + deactivation hands free activation pop-up
go ahead with it.
For me the old method worked.
I tot to ZVE, unlocked the phone using same old thing & then flash the OTA from cache.. simple.
