Friend of mine gave me a Droid Razr from Rogers to try and fix. Phone would constantly reboot, but not at a specific interval. This all happened while it was on stock firmware. No upgrade available from Rogers, so I couldn't try that, plus factory reset/wiping cache didn't work either. Friend said I should do whatever possible, so I flashed the "The Artic" ROM. Everything works perfectly. No reboot, nothing.
It is a Rogers phone, and I need to unlock it, and when I put in the microSIM from a different provider, nothing comes up asking for SIM unlock. When I go into phone status, everything says unknown, including the IMEI.
The baseband box says unknown as well.
Anything I can do?
When I try to go *#06# the box comes up for IMEI, but it doesn't have anything on it. Corrupt IMEI?
How long ago did he get the Razr I hope he didn't get the two I returned as defective? LOL.... The two I got the first one having this random shutdown issue for some strange reason it would just turn off by itself. I can't seem to track the problem down since it was factory reset and nothing install but still did this. The second one just completely turned itself off and wouldn't come back on. The third did the same as the first but I managed to send it to Motorola for repair and they reflashed it, seems ok so far. I'm wondering if the Rogers Firmware has something to do with this?
I have no idea how long ago he got it. His warranty was out though, so Rogers wouldn't take it back.
Either way, apparently I don't have an 'EFS' folder. I used Root Explorer to check and there is nothing there.
How would I go about fixing that?
The weird thing is I can use WIFI on it. I thought it stored the WIFI addresses in the EFS folder?
Or perhaps Motorola phones don't have EFS folders. Anyone?
Did a factory reset, no EFS folder.
Originally when I got the phone, before I flashed any kind of ROM I put in a foreign SIM card and the 'network unlock' box never came up.
I'm beginning to wonder if the EFS folder was gone to begin with.
Because I just checked again, and its not there. Not even after a factory reset.
Yeah, not sure what else I can do. Went back to stock 2.3.5 and installed after market radio, and both times it says unknown IMEI. I think this phone is pretty much hooped.
Alright, so first of all, my Samsung Galaxy SIII got some damage, and then we brought it to a repair shop. They changed the motherboard, and then returned it to us and it was working fine. The only thing is, the Android version is still on 4.0.4, and whenever I boot the phone, a T-Mobile bootloading screen appears, and it annoys the hell out of me. So, I flashed Android 4.3 Jellybean using Odin. Yet, after the update finishes, the phone won't make a text or a call. It always says 'Not Registered On Network'. So here are some notes of the phone's status...
1. I tried to use Ariza Patch, yet it didn't work.
2. The IMEI's number is not changed to 0000 or anything, it's just a 15-digit number and has a '/01' at the end of it.
3. The signal is full.
How could this be fixed? Is there anyway to fix this? It would be very much appreciated. Thank you!
Take it back to the repair shop and tell them they botched the efs folder after their repair. You might be able to get a network by reading the sticky thread on efs, or the patch thread but you will always have problems with updates unless you get the efs folder sorted by a professional.
I did return the phone, then after that, they replaced the board again. After I tried to update it to 4.3 once again, the same thing happened, still not registered on network. :/
Messed up with my G925F!!!
Hello , my phone suddenly was not able to make or receive any calls or joining 3G/4G network or SMS. In other words, I was out of service although my SIM had not problems to enter the PIN password and I could see signal bars.
After a little research I discovered that my IMEI and S/N number had been changed! Especially, the IMEI number became 350000000000006 (fake one) And I believe this is the reason my signal went off!
So , I just managed to download smart switch from samsung and choose "emergency software recovery and initialization -> device initialization" in an attempt to revert it to stock rom and settings (is this method unroot the phone too?)
But after this long downloading finished , the phone didn't boot , I only see the samsung galagy s6 edge logo stuck!!!!
So , I decided to root the phone again , following the guide here (link-->), zidroid.com/how-to-install-twrp-root-galaxy-s6-edge-on-android-5-1-1/
(in short words , I installed the twrp recovery with odin and I flashed 2 zip files required, from an usb-otg-flash drive, via the twrp recovery install button) and then the phone booted normaly , but the problem with the signal and wrong IMEI was still there!
I feel that I am on dead end , I don't know what to do , I am thinking about sending it to the location I bought it but I am afraid that the warranty is lost.
Please help me restore my phone back to normal
After repeating the whole procedure several times , now my phone does not recognize SIM card at all , as if it was never inserted , wtf?

So you mean that there isn't any way of backing up the IMEI number first before rooting or changing a rom/kernel/recovery to the phone in order not allowing this IMEI bricking happen again by means of restoring from its backup?
I googled a lot and some people suggest that they can backup EFS in some way. What is EFS exactly and how it is related to IMEI?
Also wouldn't be a good idea to find a way to backup my entire OS/firmware (not just IMEI/EFS) before doing anything , in case to save money and avoid the same bricking?
And yes , I have sent the phone to samsung service , it will cost me around 320 euros , because they discovered I changed kernel/rooted the device , and they will change motherboard.
I cannot help the phone without being rooted , I love rooting but I cannot understand why suddenly IMEI got bricked.....does it worth to take risk and root my phone again? But I want IMEI or entire OS backups first before doing that and I don't know how to achieve this without rooting first...
Please help me if you could.
You can backup your full os using twrp recovery
Also your IMEI
In SAMSUNG devices imei number stored in efs partition that's why people asking take efs backup before flashing any Rom

Me too! I have the exact same IEMI number! Mine stopped working after about a month. I tried to return to seller no response. I tried to send phone back they would not accept phone, so it is on it's way back to me. Once I get it back I will try what you did.
I have taken it to factory settings 3 times no luck. I will try your process once I get me phone back.
Thanks!

I did contact one of those fellows a reputable one that can change your IEMI. Well once he heard that crazy IEMI number, he said because it was changed once before to something like he doubted he could change it again and save my phone. To try he charges 100 US plus I have shipping there and back. Yikes.
So any advice you can give me I would truly appreciate.
Thanks!
g925f imei repair
new g925f repair method
repair ok
:good::good::good::good::good::good::good::good:
Mine went down recently with the exact same IMEI and no SN. TWRP was failing to restore the efs partition damaging the files in the process. Long story short, I had to manually extract the efs files, copy them across and fiddle about with permissions but I'm working again.
That nugget rings true - always backup the efs before changing anything.
But for that reputable fellow to say that the IMEI had been changed before because of what it had become, and insinuating that the imei couldn't be changed more than once was complete twaddle. I wouldn't trust him near any of my phones.
On a lighter note I'm sure there's got to be a member on here would sort it for beer tokens
Happened to me, I thought it was faulty ROM and all but then I realized it was simply apn setting. Resetting it to default did the trick. It can be found in Settings > Mobile networks > Access Point Names

Since this thread is quite old and people keep answering , I want to end it like this:
Back then I didn't avoid to pay about 300 euros to replace its motherboard to a samsung shop. But I learned lately that the issue was due to an app called "USB OTG Helper" (https://play.google.com/store/apps/details?id=net.shajul.usbotg&hl=en) which allows you to insert NTFS USB flash drives to your OTG phone but also enables a system partition , including EMS files to be visible.
And you can guess what happened next , I deleted this system partition which this app made it visible and yes , my IMEI was gone!!! After some months , I repeated the same delete thing , but previously I had backed up via TWRP the EFS and MODEM partitions. My phone lost IMEI again , as expected , but after restoring EFS and MODEM , the IMEI was back!!
To sum up , never delete files or partitions that look like "system" like bluetooth and imei folders when you are root AND always have a backup of all your rom via twrp or something else before changing/deleting/flashing anything related to your system.
I used my galaxy mega 2 on AT&T's network for about 4 months without any problems until I decide to root it with either Kingoroot or Kingroot and since then i've been network blocked because it changed my IMEI. I want to change it back to what the sticker under the battery says but have had no luck. So far i've tried flashing it using odin and the z3samsung tool. It was 4.4.4 but now it's 5.1.1 KitKat because I can't try to downgrade because the "repair" firmware 4.4.4 always fails. The bad IMEI 350050500009692 i was told that this imei was a default when your imei gets erased by some mobile tool pro via email. I won't publish the good/true imei that's on the sticker. Baseband G750AUCU3B0H4 , Build number LMY47X. G750AUCU3BOH4. Also I get an error when using the z3tool to write NV data, it says "security damaged". Being the bright person I am I didn't back up anything prior to the first attempt but all I need is the IMEI restored everything else seems to work fine. I'm stumped and need help.
Thanks to all or anyone
ME TOO ON SAME BOAT , pLEASE ASSIST ME ON THIS ISSUE
I've bought it like this and i thought it can be repaired, i had a similar problem with my i9500 a while back and i fixed it by flashing some modem on the right firmware, i don't even know what i had done but it took me 3 full days of trying, truly frustrating. I haven't got the phone's imei as it came without a box or accessories hope you can help me out !
Here is what i've tried so far :
- Flashing 3 different 6.0.1 stock firmwares, none of them worked and after every single flash i would encounter device root key error, i have no idea why but it's easily solvable by flashing some kernel as i've seen on some ytb tutorial.
- Backuped the efs folder from phone root on PC then deleting it from the phone root, restart the phone and proceed with replacing the nv_data.bin and the other similar-named file with the ones i backuped then changing permissions to 1001. <--- This i've seen on some forum, i thought it might help, but it didn't change anything!
I really hope you can help me out, i'm bored of searching the web for answers, most of solution i've found are related to some z3x box or octopus and i believe these cost a lot of money and there is no service in my city that can repair phone's imei
Heloo
Hi i had same problem 920f after flash a wrong rom the only fix is octopus box ...they must rewrite imei it cost me 30 euros!
As i said, there is no such service in my city (I live in Braila, since you're romanian too ), but i'm pretty sure it can be solved without special equipment. I think the owner flashed the 6.0 using odin and spooked when saw fake imei then rushed to sell it. It happened the same to me 2 years ago with a i9500 but i eventually solved it without prior backup.
