Hello, I was trying to unlock my galaxy tab P7500, and for some reason I lost the efs backup, or it got overwritten or something, base line, I don't have the backup, now the IMEI is 004999010640000 and the serial number is 00000000000, obviously, it does not connect to the network, I've tried every post I found that states I can restore my IMEI, flashed older firmware, flashed the original one and many other things, but none seems to work, so now I really don't know what else to do, I know my IMEI number and my serial because is still in the sticker on the back of the tab, and is in the sticker on the box, and is on the purchase receipt.
So any ideas what should I do?
GT-P7500 from movistar venezuela, now on Official ICS LQ8 ITV
Do u still have the imei number that on the back of ur tab? If u do I advise to you is going over to t-mobile gs 3 dev section. They have a tool call nv and imei injection and give it a shot.

thanks!, is that a web site? or a office? I'm currently in Bogotá, Colombia, so if your advice needs me to take the tab to a t-mob office I think is not going to be possible.

so?? any more ideas??
Hi folks! Im hoping someone can help me sort this out.
I rooted my n9005 using CF-root to install custom ROMs. I wanted to back-up EFS and searched google play store for an app, I found "Efs by BORIS.X.1" app.
This app is not to be used for NOTE 3 as per warning by the developer but I'm so stupid not to read. :crying:
My phone got into a bootloop and if I was able to pass boot up, after few seconds it would restart. I have scouted the forums for fixes and I have found one. I am now able to boot my phone normally but cannot make calls and sms.
My IMEI is unknown, I already fixed it using "EFS pro" tool, IMEI is showing now but still no calls and sms. I also noticed that the serial number is not the same as the one written at the back of the phone. I have read that restoring EFS solves this problem, but I don't have EFS backup.
To sum things up, the phone now boots up normally, IMEI is showing the right one, serial number still incorrect, can connect via WiFi, can't make calls and sms but phone has signal bars and says "Emergency Calls Only".
When trying to make a call, "not registered to network" shows up.
Im on MJ6 BTU firmware with root and TWRP recovery. I originally got my phone with MJ1 KSA firmware.
Im planning to bring my device to a nearest samsung sevice center but im not sure of they will accept it or if they can fix it even at a price.
It's been literally days since I had a good night sleep.
Please help. Thanks!
Having the same problem...How did you get your phone connected to efs pro? Every time I try my device reboots :/ Is it possible in recovery mode? Which recovery?
Did you find a final solution?
•You need to be rooted first.
•Make sure USB debugging is enabled.
•Dial *#0808# on your phone and select the same items in the image
•Connect your phone to your computer using the USB cable and open up EFS Pro.
I still haven't figured out the solution of my problem.
I brought my phone to the nearest Samsung service center but their solution is just to replace the motherboard which is very expensive.

Thanks mate! I tried that before, I was able to get out of the bootloop but still no calls/sms/data connection.
I'm going to try it again though.
Change 12 in that script to 11 for n9005

tried it but still no luck.
still no calls, sms, & data.
the serial number is still not the same as the one printed on the sticker of the phone.
maybe I really need to change my motherboard?

My phone is fixed now. The one and only solution that worked for me is replacing the motherboard. Samsung Saudi did it, and I paid a fortune for it.

Hello everyone. First of all I want to say that this is a great forum with tons of valuable information. You guys do excellent jobs here. Now. I have a recently purchased S4 with AT&T. It is imperative that I get this phone unlocked TODAY. I am going in for surgery and my daughter is going to be left alone at home and I need her to have a phone to be able to contact me at the hospital if need be or in case of an emergency. I have tried all of the way that I have found on here to unlock this device and have not been successful. I cannot even get it Rooted. I tried with MotoChopper. I tried ODIN, King, and whatever the last one is. I have tried the *#0011# and it goes to the service menu but when I key in the number one, a screen flashes real quickly that says menu not exist. then back to the service screen. I do not know where to go from here. Can someone please assist me with a step by step tutorial on what needs to be done? I would be extremely grateful. I am standing by refreshing the page hoping for responses. Thanks!
I assume you want to sim unlock it? Do you know what firmware version you're on?

You're on nc1 firmware, look at your build number, it's the last three characters. Try this http://forum.xda-developers.com/showthread.php?p=54932702
You might have to down grade to nb1, idk for sure. If you have to there is an Odin flashable tar file in the general forum.

I tried everything in that thread also. I do not know how to downgrade. I also run a linux machine. i do not think that ODIN runs on Linux. Does it? Thank you for the rapid responses.

Odin won't run in Linux. You might be able to run it in a Windows vm. I'm not that familiar with Linux. Heimdall will run but I'm not familiar with that either. Sorry man. You could try Google and heimdall

Seems I am kind of screwed. Haimdall does run on Linux but it wont root my phone. it says that it did after I run it but then it's not. So weird.

Have you tried to root with towelroot?
Sent from my Nexus 5 using XDA Free mobile app
Help me out guys,
Why do you need to root to be able to have daughter get ahold of you?
Why do you need to sim unlock? Are you on different carriers? Texting? etc
Can you get two prepaid phones that would work while in hospital?
Below links:
1. I used this to set up adb/fastboot on my iMac--need it to use Heimdall. I had some links to Heimdall, but must have deleted them. I can always use my son's Windows machine if needed--

2. Rooting with SafeStrap--

Those are complicated procedures and take time to learn w/o breaking your phone which you don't want to do atm.
With sim unlocking which is for using phone on another carrier I have no exp with. But, thought Obama passed law requiring carriers to give you that info. Otherwise, maybe someone else has done it on your model or Google alot.
Again, I am confused on why you need to sim unlock or root--sorry--
Hope you get it sorted in time--:good:

Hello,
I answer here to help also someone else in case has the same problem.
Fiest thing: you wrote CDMA module, what variant is?
The GT-I9505 has a LTE/WCDMA module, not CDMA.
Have you touched something with secret menu codes? If you don't know what they are, the answer is no
What carrier do you have?
Have you roaming enabled?
You data plan reduces connection after a total GBs used at maximum speed?
Try to flash latest available modem fw along with latest bootloader, you can find them here

Thank u for ur reply,
First you are right I'm talking about the LTE/WCDMA module, and yes i messed up a little bit the with the secret menu codes but only after i got the issue, not before that.
I'm from morocco so the carrier is a moroccan one called inwi, the carrier does not reduce the speed, when u consume the GBs given the service is suspended.
the issue appeared when i was using wanam lite 3.1 i'm using wifi at home all the time so i couldnt notice until i went out and used data, i noticed that i only have edge in locations that used to give me H+, so when i tried to force wcdma by choosing wcdma only i got emergency calls only.
i messed around before with a couple of bootloaders and modems, I still cannot figure it out
your help is appreciated, thanks in advance
I had the same problem on Wanam. What solved it for me:
Use Shortcut Master (lite) to go to this menu: 4636
Then go to phone information and change the bandwith to something else. Then set it back to LTE/WCDMA or whatever works for you. Strange but it worked for me.

Get the network cable changed or change it yourself.
The only easy "non software" related solution.
Or maybe if it is in the software, tried flashing the stock rom or any ither custom rom after a full wipe.
Mine was with the stock rom but ozcan rom + data wipe has solved it..
Not i get H+ in only wcdma amd E/H+ in auto mode. (depending on the network area)

help?????......
same problem now as mine my IMEI just became 350050500009692 /01 emergency call only why???
some nice paper weights at least lol none of you have efs back up ? tried restoring it if you do common rule with samsungs all ways back up you efs folder
the sad thing there is mine I don't have my backup
Try NV restore (If you have it Pre-backed up on your phone from factory- at least mine did not have on the N910C but it existed on my N910F) ... Dial: *#0011# , then Menu>Back, then Menu>Key Input> then type Q0000.
After that I don't know where the NV backup is (I forgot, and I don't have the phone now), but you should be able to search here on xda or google it up...
I hope your Exynos has a NV backup....
Good luck
