II went to bed with my Note 10.1 N8000 with Gnabo ver. 6.5 ROM and a HTC M8 on the table by the bed a week ago.
Before sleeping in I heard that I got a SMS on both devices (two simcards with the same nbr. from provider). As I was almost sleeping I didn't check the SMS before morning. On my HTC there was no SMS.
My Note 10.1 showed recovery screen. Tried to boot but without any luck. The EFS folder was corrupted. And sorry to say, the EFS folder backup I created years ago is nowhere to find. So now I have lost my Imei and have no network.
I have used the tool Chimera tool to get a fake IMEI for testing and check that there are no hardware faults with the Note 10.1. Everything is fine.
But what happend.
1. Service SMS broke my tab?
2. Gnabo 6.5 have bugs that can make the tablet unusable?
I have read numerus threads and articles about how to recreate the original IMEI, without any luck. And some threads and sellers says the the only way to recreate IMEI is to use a special cable.
But the point is, repairing IMEI can be done without cable. But how to recreate it myself?

Hi all,
Thought i'd post my findings here rather than muddled in to the other i5500 thread (will this phone get it's own device area?).
This is what worked for me and may hopefully help others to do the same. Please post here if this works for you also.
I bought an unlocked, unbranded Samsung Galaxy Europa for my girlfriend for christmas.
It is being used on a Tesco mobile prepay sim (uses O2 network).
It immediately had this duplicate text issue from some contacts, where duplicates of the same text would come in at random times, and some messages did not come through at all. A few googles later shows it is quite a common problem for O2 / Tesco users.
The phone also had a faulty sync / charging port so it was returned.
The next phone seemed fine until I made the mistake of updating to the latest firmware through Kies (the previous handset was already up to date). The duplicate text issue returned to the new handset which pretty much made it un-usable.
I dug around on the interwebs and the only fix I could find seemed to be a factory reset, but this didn't solve the problem for me.
I wanted to roll back the firmware via Kies but couldn't get this to work after trying to modify the registry. Hopefully someone can update here if they work out how to roll back to previous official updates via Kies. To be honest, I don't think Kies is any safer than flashing firmware via Odin.
I have tried out a number of firmwares from samfirmware.com and have found a couple that don't seem to have the duplicate text issue and others that do. The froyo update is just ugly and also seemed to have the duplicate text issue. Hopefully someone will release a custom froyo rom as Samsung seem to have made a mess of it!
*********
What worked for me:
I used 'Odin' to flash the firmware 'I5500XWJG9' and followed the instructions on page 1 of this thread to do so: http://forum.xda-developers.com/showthread.php?t=781149#
The firmware I settled on is 'I5500XWJG9'. It's a European firmware but not a UK one so you need to change the default language and set up your APN in order to get your internet and MMS working. This is acceptable if it resolves the text issue I think.
After updating you may recieve the last few of your duplicate texts or some that you never received previously.
Something strange I noticed was that the message centre number seems to be incorrect (for tesco mobile anyway) or the menu to display or change it does not work correctly.
If you enter *#*#4636#*#* on the dialler and go to phone information and scroll down, you will see 'SMSC'. Click 'Refresh' and it should display your service centre number. You should also be able to update it but it doesn't work on this phone. I suspect this may be something to do with the problem but texts seem to work on this firmware anyway.
Bah, we had a few duplicate texts after a week. Not as bad as before it would seem but still there. How annoying!
Hi using a Samsung Europa on Giffgaff (o2 derivative) and using the originally provided usb link cable. It used to work, but the first time I plugged it in, the language was set in german for a joke, and I got very confused about Kies and said 'No don't do that' - now my PC doesn't seem to want to know about my phone no matter which usb socket I plug it in. I have it in download mode right now and Odin can't find it at all.
Any thoughts - this repetitive text issue is driving me up the wall (x100 copies of the same text over a week and all my other non-O2 messages getting stuck!) ?
I know this is an old thread. But spent so many days reading all those stuffs. Finally contacted samsung service centre and they says they can't repair my phone since its not manufactured in my country. Tried repairs like '' GSII repair'' and lots of other. Am not sure what I did. Deleted efs folder and copied, pasted. Nv files restarted. But of know use. When I tried inserting another network simcard(my friends) . The imei didn't change. But I was able to make phone calls and 3g. Bought a new sim of the same network. But I couldn't use it to make calls. It shows network not registered(like my previous carrier). The only thing I am able to do is I can use 3g. And I am typing from this same phone. Thank you for reading this..

If all you want is the original working condition you might be able to restore to stock.
Make sure to select the version for your device/region.
Restoring Galaxy S2 to Stock
http://forum.xda-developers.com/ galaxy-s2/ help/ restoring-galaxy-s2-to-stock-t1799241
After looking at that you might try to flash a custom ROM, now that you can revert back
Use your recovery mode to make a backup of your current state before you do anything further.
If you have a terminal emulator do "reboot recovery", or find a menu.
Alternately there is a button-press sequence or this app here:
http://forum.xda-developers.com/showthread.php?t=1410569
Might use a backup app on the internal sdcard. Use odin/adb to push/pull files to from the phone and computer to keep the backup safe. Moving to the external (removable) sdcard is also good.
Hello everyone.
I recently attempted to install a custom kernel (ElementalX) on my Nexus 5 D820. During this process, I encountered a bootloop while installing TWRP, which is probably the event that has caused the nightmare my phone has been in the past few weeks. Essentially, ever since then, LTE has not been working on my phone, and the rest of the cellular connectivity has been quite bad. Actually, LTE does work, but only for about 10 minutes. After this, if it is turned on, it will crash ALL cellular connectivity, including phone calls and texts, until I turn it off.
Initially, I believed that the custom kernel was the cause. I therefore flashed stock ROM back, thinking it would solve the problem (spoiler alert: it didn't). I then tried flashing many different stock ROMs, from KitKat to Lollipop and pretty much any variety of Marshmallow offered. This still didn't fix the problem. After this, I tried flashing individual radios from http://forum.xda-developers.com/goo...t/modem-nexus-5-flashable-modems-efs-t2514095, which still did not fix the problem.
I then realized that the problem wasn't in any of the files normally affected by flashing a new ROM and started reading up on the EFS partition. From what I can gather so far on my phone, I believe that I have a slightly corrupted EFS partition and that this is causing the stability issues on my phone. I tried restoring from a good qcn file as suggested here http://forum.xda-developers.com/goo...efs-backup-t2769023/post60421668#post60421668 and that has still not fixed my problem. I tried about 4 or 5 different qcn files, restoring in different order, wiping the block partitions like suggested here http://forum.xda-developers.com/lg-g3/general/request-3g-2g-lte-d850-t3300908 and that still didn't work.
But I didn't give up just there! I read from this post http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 that you could edit NV items individually and figured that maybe I could try to edit the LTE NV items to their default values. Turns out, they were at their default values and they are fine.
At this point, I thought I had tried everything, but while attempting an NV item backup using Qualcomm NV Tools in EFS professional, I noticed an odd error that kept happening. All of the NV items would back up properly, BUT, the backup process would crash for NV items 33799 to 33802 and 33810 to 33812, every time, no matter what. Also, exactly when I tried reading these NV items, the phone cellular network goes down for about 10 seconds, as it normally does when LTE is activated. I therefore believe that these NV items may be corrupt and that cellular network stops working whenever they are read, which for some reason only occurs when LTE is turned on (I'm far from an expert in this field, correct me if what I'm saying makes no sense).
At this point, I've pretty much given up on fixing the phone, but thought I would reach out to xda-devs to see if anyone had any experience with this. Not having LTE is not a huge deal, but I would be quite happy if I could bring it back.
What I'm asking: If anybody with a Nexus 5 D820 could try doing an NV Backup using Qualcomm NV Tools and see if NV items 33799 to 33802 and 33810 to 33812 crash their phone, that would be much appreciated. If I know at least that this is a problem unique to my phone, it can point me in the right direction. On the other hand, if it's widespread across Nexus 5 devices, my problem may be something else completely.
What I'd really, really, really appreciate: If a kind soul could give me a full EFS backup of their working phone, I would be extremely grateful. I'm pretty sure that this would fix all my problems, and I would be forever grateful to the kind person that does this. Of course, you may wipe your ESN/MEID/IMEI before sending the file.
tl;dr
LTE doesn't work since flashing kernel. Probably corrupt EFS partition. If some can check if NV items 33799 to 33802 and 33810 to 33812 can be backed up on Qualcomm NV Tools, that would be great. If someone can send me a full EFS backup of their Nexus 5, that would be amazing.
I dont know if it is still relevant for you but i got the same issue..
I got two Nexus 5 D821 (dont ask why two of them )
Wanted to move a full backup from the first one to the second...
I didnt know about the efs partition and what it is so i also told twrp to backup it from my first device too... and restoring it on the second device screwed my imei (showed 0)...
SO DO NOT BACKUP EFS ON ONE PHONE AND MOVE WITH IT TO ANOTHER ONE!!!! EVEN IF IT IS THE SAME PHONE TYPE!!!!
I managed to get my imei back somehow with editing NV items, restoring backups from QPST files and so on... (Worked at least 20 hours so far)
The only advantage that I have is that the first phone i came from is still untouched on his efs, so i try to backup the nv data and got the same errors as you!
I am currently working on this and got the same errors backing up nv items from the untouched nexus...
So probably thats not the problem, just skip these values and try to restore the nv as parts
If you need the nv backups you can contact me at [email protected]
Perhaps I am able to help
Brother, did you solve the problem?
Hi Everybody,
I'm looking to see if there is anybody who can change/restore my IMEI number (ideally remotely) with an Octopus Box.
My understanding is that, for all the hacks and work arounds, it's basically not possible to change it by flashing efs.img etc... not that I have backups!
I do have my original IMEI number.
Any help/advice will be appreciated.
A bit of a back story.
I rooted my phone and it was all working well for about a week. One evening I picked up my phone and the screen was black with a solid blue light. Cue numerous attempted resets via the power + vol. down keys.
No joy.
After lots of reading (mostly from here), I finally found a solution to re-flash via odin but this was failing and it all resulted in me having to re-partition the phone which seemed rather scary given I have no knowledge of all this stuff (I've been an iPhone user for the past 5 years). Eventually I got a stock ROM to successfully flash but in doing so, seem to have wiped out/corrupted efs and, as mentioned, I have no backup (mostly because I didn't know it was a thing).
My phone now is essentially a tablet, albeit a very small one. I have pretty much full functionality with the exception of phone calls/SMS because of the IMEI issue. It also says the bluetooth address is unavailable in settings, but bluetooth seems to work fine (but to be fair, I don't use for much more than connecting to a BT speaker).

do you have any news for this octopus box?
I also have to reset my number imei .... I lost it due to a flash gone wrong.
I have a note4
Hi,
My Samsung Galaxy Note 2 is rooted for couple of years. Currently running AICP ROM, Version 12.1-NIGHTLY. TWRP is installed and functional.
Couple of weeks back the phone stopped connecting to cellular networks. The SIM Card is not defective - it is working on another phone. (Even on this phone, the operator is recognised, but the signal strength is always zero.)
Otherwise the phone (?) is working fine. I can connect to WiFi and all other Apps works fine.
On checking for IMEI, it is showing fake IMEI - 004999010540000. This is not what is printed in the battery compartment. The EFS Partition is empty.
Samsung Service centre has suggested replacement of the motherboard. The cost is prohibitive factor.
I had a nandroid backup of the original ROM, however, the microSD Card has become corrupt and the backup is lost. (Original EFS Partition is no more available.)
I tried to connect the phone to ODIN/Samsung Kies, however, the phone is not connecting to these softwares. (I can browse the phone through file explorers on my computer and also copy-paste files.)
Is there some way in which I can restore the phone to working state? Or, I need to change the motherboard - as Samsung Service has indicated?
Thanks.
