[Q] Corrupt EFS partition or Hardware issue

So first lets start off by explaining the whole issue.
I have a Verizon galaxy nexus that has recently made contact with water. I let the phone dry out for a day then tried to revive it with no success so I decide to tear it down and clean it. After tearing it down and cleaning it I now get it to boot fine.
Upon boot I have zero cell service and the phone tell me the baseband is unknown as well as all of the phone information in the phone information section. I then proceeded to try and flash the basebands back onto the phone through recovery. This lead to a failure which the recovery TWRP gave a status 7 error, which would lead to the conclusion of corrupt EFS data. I have looked at the factory partition and the nv_dat.bin is there but from what I have read there should also be a .nv_dat.bak file there which I cannot see. I then went to use QPST to try and edit the nv_data.bin file but the problem is that the water has damage the usb port and there is no data connectivity through usb anymore. From what I have see through multiple post is that if you remove the nv_data.bin file the phone should use a generic IMEI which does not happen. This leads me to believe it is a hardware issue which is not impossible.
From this point I took my stock backup file and pulled the nv_data.bin from the data/radio directory and placed it in my /factory directory on the phone to see if this would resolve the unknown phone information, which it did not. There aren't to many more options that I have found to try and resolve this issue other than buying a parts phone. I was wondering if anyone had another Idea to try before I do this. I thought about trying to use mobile odin to flash back stock but I don't know if this would really help from what i have seen, unless someone else thinks this could help.
Thanks in advance to everyone ... from what I have searched I can't seem to find anyone with this same issue

Sounds to me like its time for a new device.

Thanks for the input at least that is what i was thinking ... just to add i guess another issue i found was that even without a sim card in the device does the same thing, without giving the no-sim card response when booted

[Q] No IMEI - no baseband - Tried almost everything

Hi everyone.
As i read on so many posts, my SGN one night just drop the signal. The day after, still with no signal, i checked that had no IMEI and unknown baseband.
I had tried so many "solutions" for this to work and still nothing.
It came (when i bought it, second handed from ebay) with slimbeam rom installed. I did nothing weird to it, just simply drop signal and lost IMEI and baseband. I flashed 4.0.4, 4.2.2 from google developers web, i changed the radio for a DOCOMO one, but still nothing.
As my english is not too good, i attached a photo that explain how is my phone actually.
Please, any help will be much appreciatted as i got $300 spend on this Galaxy Nexus.

Why would you use a docomo radio? Is it a docomo phone? Have you tried flashing any other radios?

Check to make sure the contact pins that read the sim card are not damaged.

One of the solutions i've read says that with this radio the signal get fixed, but didn't work

My problem isn't with the sim card, it's with no IMEI and baseband at all. Thanks anyway.

I think i just killed it.
I was trying another "solution" i found on the web, and now the phone don't turn on.
I installed an APK from the market called GSII_REPAIR and after it says to reboot the phone, now it doesn't turn on.
I read that this app is for the galaxy S2 but appear on the search for my problem's fix.

First I would put it in odin dl mode and flash stock, that should get the phone to boot again. I understand your english isn't that good but can you explain what you have tried. Im basically wondering if you have tried to play with the nv_data.bin file in the /factory directory as this may be able to make the phone get some functionality back.
The reason for the the possible softbrick is cause the gsII repair was probably deleting and replacing the wrong files ... I would probably say that this is a corrupt EFS directory and would work on the techniques out there to repair that ... either that or you have the same problem I have where it is a hardware issue and there is no real fix possible .... One method that may work the best is to try and use QPST and manually input your IMEI into nv_data.bin file ... many possibilities I just don't know what you have tried

I try to turn it on ODIN mode, and recovery mode and doesn't turn on at all.
In the same post that i saw the app, say that i can do it manually by messing with those files (nv_data.bin) but at the end mentions a nv_data file that i havent saw on the factory folder. because of that i try with the app.

so if you can't get it into odin or bootloader you have either hard bricked your phone or the battery is dead ... usually you can still get it to trickle charge if you plug it in ... if the nv_data.bin file was not in the /factory partition then i would think in some way the EFS has been corrupted or you weren't using a file manager with root access since the file is a hidden file ... biggest thing now is getting it to boot which I can only think of flashing through the bootloader or odin but i don't know everything that is possible ... someone else would probably have to help you if you can't get into either of those

HELP PLEASE !! No network after rooting

Hi, complete newbie here ... if anybody could help me with this, it'd be very appreciated.
I have a Samsung Note 2 from 3 Mobile UK, running JellyBean 4.1.2. The model number is GT-N7100, build JZO54K.N7100XXDMB2.
I wanted to root the phone, so I followed the method 1 (option 3 with custom recovery) on http://forum.xda-developers.com/showthread.php?t=2143479. The process went smoothly, and at the end, I got the message like "You have hacked the phone" or something like that from the Samsung Toolkit.
HOWEVER, after rebooting, there's no network on the phone. From Settings > About device > Status, the IMEI also shows Unknown. From File Manager on the phone, the whole /storage/sdcard0 (the phone internal storage) is empty. Completely empty, as in no files or folder inside. When connected to the PC, from Windows Explorer, the Phone free storage shows a negative number (see attached screenshot). I still can go online from wireless and all the apps and settings are there, it's just the internal storage is empty and the phone cannot see the sim card at all.
If anybody can help with what I should do next, I'm very grateful !!! Thanks !!!!
Edit: From further reading online, it seems like I should try to restore the stock firmware using either Odin or Samsung Kies ? I should also backed up the EFS folder, which I didn't do before rooting (since I thought it's a safe procedure), so am I screwed now ??!

Hi all. For what it's worth, the problem was fixed after flashing back to the stock ROM, following the steps described in http://forum.xda-developers.com/showthread.php?t=1896696 ..

[Q] Phone doesn't connect to GSM

Hello.
So my N7100 doesn't connect to mobile network. No voice calls, text messages or mobile internet. Wifi works just fine, although signal seems to be a little weaker (maybe just my imagination).
What I did and how it happened:
I got sick of Samsung being assholes and not pushing out software updates, so I decided to flash some custom ROM. I choose CM, because they had that "one click installation", so I didn't have to do a lot of work. After a week of using CM I decided that it sucks and wanted back my original android with all gimmicks from Samsung, mostly because battery life with CM was terrible, not even one day. And that's when everything went downhill. I downloaded and installed firmware for Baltic region, because I live here and I bought my phone here. From that moment my phone stopped being phone and evolved into wifi only tablet. After being very pissed and trying to flash couple different roms I gave up. Found my phones original box user manual and other papers. It turns out that my phone is made for Hungary region. So shop where I bought it must have imported wrong models (most likely cheaper for bigger profit). Flashing original for Hungary made firmware doesn't resolve this issue.
Guys, I really need help. I just want to return to stock - original firmware and reset flashing counter. Please help, and if possible in layman's terms...

Press *#06# and see if your EMEI is fine... If it says something like 000000000049 it seems to be bugged and you can try this solution:
I flashed the firmware N7100XXDMF2_N7100OLBDMD2_XME using ODIN PC and follow the below using root explorer:
- copy /efs/ to the sdcard
- delete /efs/
- reboot (after reboot I got the yellow recovery mode window floating over, no lock screen, and pressing power button turns the phone off directly)
- /efs/ will be autocreated again. copy the efs folder from the sd card to / (root explorer will tell you that the folder already exists and it will merge them)
- reboot
PS: I did not have an /efs/ backup before applying the above.

I saw from another post. Im going to try this too since Im having the same problem as you.
Find your ROM here: http://www.sammobile.com/firmwares/1/?model=GT-N7100&pcode=CHE#firmware I selected Chile Entel, but you can choose your country and company, it is the original ROM and it should fix our problem, Im downloading the ROM by now.
To use Odin, just put your phone in download mode (vol up/down + home + power) and then plug in to your PC, open Odin and at "PDA" select your ROM, then put start and just wait a few minutes and it should be working again...
After this, you should make a back up of your EFS file using a root explorer and then flash with any ROM you want (Im trying Ditto 3, it seems to be a cool jelly bean) and after this flash, you should put your new EFS file... Just the problem that Im facing is how to put this backup since the EFS is a folder being readed all the time, so there should be a program to do this, but I cant figure this out yet.

My phone doesn't have any IMEI any more. "null/null" is value given by my phone after requesting IMEI. I already flashed original ROM, problem is still here.
About /efs/ I could backup it with "File Manager"app from google play, but I can't delete it, because it is in read only.

Somehow you will have to access to edit it and you will be able to solve that problem... Otherwise go to technical service.

In order to delete /efs/ you have to be rooted, when you flash factory rom you loose root privileges.

[Q] Sprint LG G2 LS980 - no data, no signal, PLEASE help

Here is my OG post...please, anyone, help me to know what YOU would do in this case. I'm freaking out that I have a $500 paperweight I can't take back to Sprint because I'm rooted and on a custom ROM. AHHHHHHHHHHHHHHHH

Please help me, anyone. I am freaking. I flashed this ROM per the instructions (no I did not do a backup, my fault). However, although the ROM loaded, it told me I needed a T-Mobile SIM for WiFi calling to work. That may have been discussed before. That is irrelevant.
Since flashing this rom (Yes, I did the ROM, Modem, Reboot, and Firmware as said)...I can only make "Emergency Calls," I can't connect to data, can't connect to Sprint cell signal, and for the first time I can't get LG Flash Tool to work to get me back to Stock.
Can someone, anyone please tell me what to do? I need my phone soon because I'm leaving, but nothing works!!!!
Billy

Than you need to boot into recovery twrp and than you need USB OTG Cable here is the link on ebay: http://www.ebay.com/itm/13cm-Micro-U...item35d4da865d
Copy LS980 room zip file to to flash drive connect to your phone thru recovery mount usb otg than flash ls980 zip
You will be back on Sprint and after that LG Flash tool will work to if you needed

Thanks again for your instructions and help. I got the OTG, followed your steps precisely, and it SAID it installed Stock ZVC successfully (twice, actually)...yet it still will only boot back into TWRP. In download mode, LG Flash tool still doesn't work. This computer has all drivers, Windows 7, and had no issues before this ROM.
Do you have any other ideas? Now I've bought a cable for no reason. Help, please!
__________________________________________________
EDIT: I used these instructions to get me out of the TWRP Bootloop:
http://forum.xda-developers.com/show....php?t=2451696
Now I have the Stock Rooted ZVC Odex ROM installed, but STILL, no data, no signal connectivity. I try to update PRL and it says authentication error. I try to make a phone call and it says "Emergency Calls Only." This stuff ONLY happened after this (TMobile ROM). Please help me if you can. I've made major progress with your OTG instructions and getting out of the OTA TWRP Bootloop. Now how do I get past the "authentication" error and get the data and signal restored? Can Sprint do that from their side?
Edit # 2: I called Sprint, they walked me through fixing the MDN and MSID, factory reset, nothing works. It still shows "NO SERVICE," "AUTHENTICATION ERROR," AND ALTHOUGH IN MDN AND MSD my # is correct, in SETTINGS it shows my old (pre-port) phone number.
He told me to take it to a Sprint Store but clearly I can't because I'm rooted and on a debloated ROM. Please, any advice is so much appreciated.
Thank you,
BIlly

This SOUNDS like the answer...but I'm missing an EFS backup and these 2 files. Can I get my hands on these two files?
modemst1.img and modemst2.img????
Thank you... http://www.shiftpda.com/archive/index.php/t-12042.html

I've had this problem. I do think this phone can be wonky when using custom ROMs. Some people have no problem, others have constant problems, and some have problems SOMETIMES. There is no right answer so far.
I would just continue flashing different ROMs until something works. This worked for me: http://forum.xda-developers.com/showthread.php?t=2775888
But unfortunately now I have the dreaded touch dead-spot.

have you tried to tot back ?

Yes, they did (hence the reference to LG Flash Tools). It sounds likeyour EFS partition got wiped. If you didn't back up your EFS, I think you're kinda SOL. From what I've read it's nearly impossible to get back your EFS data if you don't have the files. If you can find a way to hack it out by using someone else's files, let me know. I have mine from every backup I've done and if I can remove my info from them I'll post them. Sorry to hear about your issue, hope you find a solution.

I think I have great news. I looked in my ioroot folder and found both of the files (3 MB each) that are modemst1.img and modemst2.img.
I created a folder on the Internal called EFS_Backup, and I copied and pasted those two files into the new folder, renaming them efs1 and efs2. They renamed and stuck in the folder just fine, but running the ADB commands didn't work. So I used the flashable EFS zip in TWRP and it said FAILED.
I'm thinking since I have these 2 files I should be able to fix this, right???? But...the thing that's driving me nuts is that LG Flash Tool, no matter what version, will NOT work on my device anymore. Not with either of my PC's.
Does anyone have a suggestion for what to do now that I found those modem files in my ioroot folder?
I feel like this is the closest I have gotten and now I'm stuck. LG Flash Tools never worked on Windows 8. The OLDER versions worked fine with .tot files BEFORE all of this happened, in Windows 7. Now even Windows 7 won't work to use LG Flash Tools, after I created this mess.
Can anyone PLEASE help me take these 2 files and get them to fix my EFS? I really don't know what I'm doing, clearly, or I would have backed up my EFS first. Problem here is probably same everywhere...I've always done this, never bothered with Nandroid or EFS backups, but also never had the issue of only having an internal memory on an Android device. Stupid mistake.
I would greatly appreciate any help that can be offered. I have one more day and I can still take this phone back...IF I can fix it. Thank you in advance!
PS: I Have my ESN, MEID HEX, MEID DEC, IMEI, ICCID AND IMSI - ALL POPULATED WITH NUMBERS IN SETTINGS. WHAT IS "UNKNOWN" IS MY PHONE NUMBER AND MY PRL.
