restoring efs with nvtools/qpst

hi guys, i flashed the lte modem on my phone and it seems that its wiped out my efs folders, ive been trying to restore my efs folder with nvtools and qpst, neither seems to work since somehow dm mode is not responding to them
any solns? ty in advance for any help
a couple of things:
ive already odin'd back to stock, no luck on restoring efs(perhaps im doing something wrong?) i dialed *#7284# and put it into the RNDIS+DM+MODEM mode, nvtools says phone failed to answer while QPST says that comm7(the samsung serial port) is not a phone
its pretty had to do this since the phone is rebooting itself every other minute

Questions and help issues go in Q&A
Thread moved
Thanks

Been there, sucks. For me to get out of the constant restarts I had to flash the lte modem again. Flash stock (odin) flashed cwm (odin), put the modem on my external sd card and flashed that.At least that way I could work on it a little. And below is basically what I did to finally get it to work. Hard to say all my steps as I was trying everything.
Well I dont really know how I got mine back to life, tried all the standard stuff from the threads,got my imei back but had no network,network type,service nothing helped. last resort I said whatever ill try anything now. Came across this
http://galaxynote2root.com/galaxy-n...3g4g-aws-bands-on-att-galaxy-note-2-sgh-i317/
whatever it did it restored everything (cold see carrier,network,etc)but corrupted imei, next i followed this guide

If you need this is a complete no imei nv backup I used before flashing my imei with the generator
http://db.tt/4hunZ7qy
used the imei generator, then the writer (link on post does not work for the imei generator,so found it here
http://d-h.st/vVV
Wrote my imei back and presto, back in action. Fully functional again, including 4G
Like I said this was a last resort, but worked

got it fixed on friday, was so tired that i went to sleep
basically i followed someone's post on the forum(forgot name) and flashed the tmo modem, since the mct one always gave me the bootloop, then i enabled DM mode and finally got nv tools/qpst to recognize my phone, it appears that the issue was that the drivers does not recognize the new modems..
anyway, once i was done restoring nv, i flashed the tmo lte modem and paranoid android
now i have my imei back and i can use lte
although my bluetooth address still says unknown..not sure if normal

My bluetooth also says unavailable, I would think if you are not hooked up to bluetooth then it should say unavailable. Im to scared to flash the tmo lte modem again...

Today,no mobile service - have worked hard for solution - no success

Hi there
I am in New Zealand, recently rooted with DR Ketan’s help and installed PhilzCWM. Also on Ketan’s advice, I backed up my EFS.
My problem: just today I realised I cannot send text, or make phone call. I am on X-Note ROM from 3-4 days ago. I am very sure that after installation, I had normal Mobile connectivity and was surprised to find I didn't. Not sure if my EFS became corrupted, or other ROM setting is wrong.
Under Settings About Device:
My SERVICE STATE says Out of Service
My Mobile NETWORK STATE says disconnected.
My phone number says UNKNOWN
What's weird is
My IMEI lists a long number, assumed correct and not corrupted
So if my EFS partition is corrupted I assume I wouldn't see any IMEI at all?
Far as I know my SIM is activated (I am on a company plan & coworker's phones are normal)
Just now I restored my stock nandroid and .... same thing! No service. So I doubt it's even a modem problem.
Guys I'm screwed, any tips what settings to check etc??

sounds like your IMEI is invalid. i had something random recently. all my flatmates use iphone 4s. they had no signal when @ home. cant send texts etc. wifi works.
then next day my LTE N2 did the same thing. I changed MODEM/BASEBAND problem corrected it self. went back to old MODEM/Baseband. no problems since.
only other thing i can think of is, someone has reported your IMEI to police or your provider..
does it say "NOT REGISTERED" ? or something similar where your provider name appears?

Hey thanks for th tip.
My phone recognises Vodafone as my provider but still won't connect.
I will try flashing a different modem, I may not have paid enough attention to different versions when I flashed the aroma installer.
Thanks, I'll report back.

update: Vodafone shop confirms my SIM is 100% good, and it works in another phone. So I think you're right, my IMEI is fukt.
I was told by Voda that my proper IMEi is listed on my phone innards. The IMEI shown in phone settings is waaay different. So it's corrupted somehow. I gotta familiarise myself with how to flash my backup image. Damn just what I need on beer day Friday

I restored my backup image of EFS/IMEI - it solved my problem.
Because there was an IMEI listed in phone settings I wrongly assumed it was the correct one. So flashing ROMS can muck up your EFS.....thank god for backups

you can still use the custom roms. just if your IMEI stuffs up, there is methods to reset it. i had to do it once. wasn't that difficult but was rather troublesome. i just wanted to use the custom rom at the time.

[Q] Baseband Version Unknown!!!! Help

A few days ago I purchased a Verizon Galaxy Note 2 off of Craigslist. When the guy brought it to me I was able to test the phone with my 4G chip. It was able to make calls and access the internet. Once I got home I noticed that the phone would constantly go into a Demo mode and erase any changes that I had made to the phone. Instead of calling the guy that sold me the phone I decided I would just go ahead and root it.
The first attempt at rooting the phone ended up as a disaster. It was constantly rebooting after the splash screen. I later found that this was an easy fix. I had decided to "Nand erase All" and then it would not even boot. I finally found a Root66, the phone came up fine but I had no connection to Verizon with or without the 4g chip. I looked through the phone settings and found that under the "Baseband Version" it said unknown. Since then I have tried flashing in with other roms. Right now its flashed with KIES_HOME_I605VRAMC3_I605VZWAMC3_1098177_REV04_user_low_ship.tar.
Its still says the Baseband Version is Unknown and the only thing that works is the wifi.
Please HELP!!!

I think your EFS has been messed up..what you should do is backup your current EFS even though it's highly damaged.... find a way to recover your EFS search on XDA ..EFS repair or EFS recover if all fails flash a genuine stock ROM and retry the repair or rebuild of the EFS... also as it's a demo phone...there could be other complications..I'm not sure.

seems like damaged efs.. if you had backed up the efs,just try flashing older modem. but if you never back up the efs,it will be very difficult..i suggest you to read all the threads about restoring efs and hope you can fix it.

http://forum.xda-developers.com/showthread.php?t=2392632 This thread should definitely help you. There are all possible ways you can restore your EFS done by @tamirda . I just got my baseband version back on my Note II International GT 7100.

[Q] Weird IMEI issue after Unlocking/Rooting

I have an E980 (US AT&T LG Optimus G Pro), and I noticed a weird issue. Just recently, maybe a week ago, I was checking for software updates and it says "Your phone is not registered yet." I did some searching, and eventually found that my IMEI reports as "0". I have googled this issue to no end, but everything I could find about it were people reporting that it said "null" or "000000000" AND they had no network functionality.
That's the odd part, my carrier network is (so far) completely unaffected. I can still make calls, texts, use data, etc BUT cannot connect to check for updates. I know it sounds like a small issue, but it's really bothering me. When searching for ways to restore an IMEI, I found lots of information about it being linked to the EFS files (which I did not create a backup for when I used FreeGee to unlock my bootloader >.<)--but again, I am led to believe if my EFS were completely gone or corrupt, I'd have no network connection. Am I misunderstanding?
What would cause my IMEI to be 0, but still allow me access to my carrier's network?
I am willing to start over from stock, but I am unsure of which options are safe/effective (Factory Reset in settings, full flash from a stock rom, etc?)
Thank you in an advance.
EDIT: I did a little more research and I suspect that, while I'm using the stock LG rom, I did flash a patch to remove the shortcut buttons in the notification pull-down. My latest assumption is that the modification is making it (misread?) my IMEI number, but for some reason still allow me on the network. So, a new question: Would anything correct this short of a complete reflashing to stock (like with LGFlashTools or something)?

[Q] Mobile data suddenly dropped

I'm running CM-10.1.3 (stable) on my phone (T999) with the UVMD5 modem and last night I lost all signal for about 30mins. I rebooted a few times and toggled air plane mode on and off without any success. Eventually, I got signal again but no data. I can send and receive calls and SMS but I have no data connection (can't browse, no email notifications, etc.). I have tried all the options under the Network Mode settings without any success. Occasionally, I'll see the "E" sign for Edge/2G but there is no data available even then. I also tried updating the modem to UEMJ4 and UEMJC but observed no changes. WiFi works just fine. Could this be a hardware issue? Is the antenna somehow damaged? Is there anything else I could try?

Try another Kernel. If that does not help, Odin flash to Stock. If that too doesn't work then suspect tower issue.
Hardware is a possibility. But lets not get ahead of ourselves

Thanks, I'll give that a shot and report what I find. I doubt that it's tower related since I'm having the same issue at home and at work and my roommate, who has an original Galaxy and is also on Tmobile, is not having any problems.

I flashed stock JB 4.1.2 (UVDMD5) using Odin since I had it laying around and I'm still seeing the same issue. What else can I try?

Check your APNs. Those are under Settings > Advanced > Network. Its called Access Point Names. It should be set to epc.t-mobile.com. See this thread for details.
Try UVDLJC or the prior version to MD5. If that too does not help then take to T-mo for antenna Repair.

Check your IMEI number. If it is zeroed out PM me. Otherwise just let us know here, (but don't actually post it).

The IMEI is 0. I never backed up the EFS folder but I was able to get the number from tmobile.

I have been having the same issue since June 2013 after doing to 4.1.2 OTA update from T-Mobile, at the time I didn't realize the IMEI was listed as unknown. So for months I have not gotten a cellular data connection better than Edge. Also after that update trying to check for a software update on the phone resulted in an error, and Kies told me my firmware was not supported for upgrade. Looking in some support forums and talking to T-Mobile got me nowhere, so I have just been dealing with it.
Wanting to upgrade I recently used Odin to load the official T-Mobile 4.3 ROM on the phone, actually hoping that would fix my issue (still in the dark about IMEI) which it did not.
I had never backed up the EFS folder, since as a standard user I had no idea what it was and while performing an update from my provider I didn't realize anything would need to be backed up outside of Kies. Now that my warranty is expired and having to take matters into my own hands I am on a quest to find a fix, however I don't want to "brick" my phone in the process, at this point I know enough to be dangerous.
Currently;
Android 4.3 Official T-Mobile ROM
BASEBAND is good T999UVUEMJC
Kernel 3.0.31-1962493
IMEI is Unknown
Looking at some other posts here at xda-developers I tried to follow some instructions on repairing or restoring IMEI using NV reader/writer, however I cannot get NV reader/writer to connect to my phone.
I have noticed in 4.3 when using *#7284# in the dialer the QualComm settings are no longer present, only MODEM and PDA are available.
I have poked around in Service Mode *#197328640# and found a setting that I thought might help, but I have a feeling it is the same thing as 8#7284#
[1] UTMS > [6] COMMON > [4] DIAG CONFIG > [1] USB or [2] UART
So at this point I don't know how to proceed, again I am not thrilled about loading a custom ROM, or really any ROM for fear of making the issue worse or bricking the phone. I have read a lot of posts about no longer being able to make calls due to IMEI issues. Everything works right now except cellular Data.
