Hi all, as the title says, my efs folder is inaccessible. Firstly let me explain. I bought a phone, it had the Paul pizz rom in it and I didn't like it. So I flashed the resurrection remix rom. It didn't have all the bells n whistles I wanted, so I tried the official res remix rom. Somehow I ended up with an efs problem. I ended up with an efs invalid argument error and from what I read, I did the whole adb efs fix. The error was gone. I ended up flashing a repair firmware back to bog5 and started from scratch. I worked my way back up to installing the modest rom and it works 99% flawlessly and I am happy enough to keep it. Here is the catch, I used kingo root and have ended up with a bad keyboard lag that's driving me nuts. It is unknown to me if the kingoroot caused the efs corruption or if it was just a bad flash going from one rom to another. I have tried several root browsers, made sure they all had root privileges, and no matter what, I can NOT get access to what's hidden in my efs folder. They always say it's empty. Now, here is the kicker, I got another note 4 for my son. Downgraded from 6.01 to 5.01 bog5, then up to 5.11 and flashed the modest rom on his. Instantly his phone has access to the efs folder. My note 4 works, can make calls, text etc. Imei is shown in settings, all info shows in settings as normal except one thing, on my phone it says configuration version not available whereas on my sons phone it gives a configuration version. I just can't figure out how to gain access to the efs folder to try to fix this extremely annoying lag. I DID make a complete backup of my system from when it had the Paul pizz rom, so the efs partitions should be intact there but I don't know if that would help or even where to start. Can someone please help?
Well, I just fixed my phone and thought I would share what happened. It seems that the guy that loaded the paulpizz rom on the phone before I bought it used a different version of twrp. He used a version for n910f, whereas when I began my rom search, I used one for a n910v because thats what the phone is. I was having a hard time with it so I reverted to stock, rooted, installed verizon twrp, and bam! No efs access. The difference in recovery programs is what screwed me up in the first place. I figured it out when I tried to restore his rom backup I made. The efs files were not working when it restored. I remembered what version of rom it was, and tried a twrp for 910f, and voila! So, now I have all functions working as blazing speeds, can actually access the efs folder, and no more damned lag! Big thumbs up button to me!

Okay, I was able to get into pink screen by erasing the dload folder, removing the battery, and connecting to my PC via the USB cable. I then copied CWM 5.0.2.7 over and then flashed Stallion-51-ICS onto the phone. I now have a very fast, rooted and customized U8800-51, BUT no mobile service. IMEI and APN info is correct but it won't access the mobile service that our other phones access, SIM is the same one that I use in my current phone.
I know you are supposed to back up the IMEI partition and APN before flashing a custom ROM, but since my phone got broke trying to restore a full backup done with CWM I was caught off guard.
Still looking for any suggestions you all might have.
Seriously???

Not to be negative or anything but I think this is the least responsive forum on this site. I have spent hours searching for possible solutions to various problems I've encountered over the past several months, asked several questions and received little if any help. I was only able to get back from a bricked phone to where I am now by using information found on other websites. Pretty sad if you ask me.
In contrast, whenever I have asked a question on my tablet's forum I've received fast workable solutions/answers to my problems/queries. The threads are informative, well organized and contain answers to any situation I have encountered.
Granted, my current problem with my phone is my own fault for trying to customize it. And I suspect part of the problem is due to the age of this phone thus most of the "experts" have moved on to other ventures. It is also hindered by the lack of information available from Huawei and the service providers.
All of that said, if anybody has any suggestions for how I can repair the ESF partition or whatever is causing this lack of mobile service issue I would be extremely grateful. It isn't the end of the world since i have a new phone (Consumer Cellular) that I am currently using but it would be great to get this one working since it's much faster and more streamlined than my stock Consumer Cellular version.
I have experienced something similar on my regular U8800, and it seemed like there was a baseband & modem partitions conflict. In stock 2.3, there should be some kind of hwefsupdate tool, it may be renamed though. This tool gets run on the first boot after 2.3 and it restarts the phone shortly after. Try to reinstall the stock ROM, see what happens. It can be fixed in strange ways - for example, my original U8800 got a USB failure, so I sent it to the repair. I had 2.3 installed. When I got it back, they tried to write over some old 2.2 firmware, which softbricked the phone. Being clueless, I wrote the 4GB image of some other phone's image on my phone, and got everything working again. Then, when I tried to write back my original IMEI, I got the same issue as you. The only way to get it right was to rewrite the "other phone's imei".
The baseband/modem errors are actually very hard to debug, hence no replies. And since it's a Huawei, these guys have even failed to provide a good update system, as seen from the IMEI getting nulled issues. The mmcblk0p5 stores the OEMInfo of the phone, it contains serial numbers & other information about the phone (like accelerometer position up/down for example). It also has the boot image (the very first splash screen). The data is loaded onto modem processor, which provides an API to let userspace access it.

Thank you very much for your reply. It seems that you have found the answer to my problem. But unfortunately, I don't have a copy of the original stock ROM. My phone is the -51 version and any links I have found to the stock ROM are broken. There is a version I found but it is for Venezuela and I don't think it will work. I am leery to try it and totally brick my phone. My backup is apparently corrupted. I backed up my new working phone with Disk Image and attempted to restore it to the broken phone but all that did was cause it to come up to the ATT logo screen for a few seconds and then shut down. It wouldn't do anymore than that. So I restored the Stallion 3.5 image I made and am back to a great fast tablet with no phone service. I also tried backing up my IMEI on the working phone and restoring it to the broken phone but that had no effect.
It is my understanding that the -Pro version of the ROM will work, but I don't have the stock image of that either. I suspect it work might since I was able to use the -Pro version of GB on it. All of my internet searches have only turned up custom ROMs and other desperate people looking for fixes for similar problems or worse. I agree 100% with your assessment of Huawei's lack of meaningful support. It really is a shame, because these phones aren't half bad when they have been customized and OC'ed a little.
I have just about given up on it and resigned myself to using it as an MP3 player for my car system. I have learned my lesson and am leaving the working phone stock. It is rooted and I have cleaned off all of the bloatware, and set it up so most apps run from my SD card, so it really isn't half bad. At least it works.
Again, thank you for your reply and advice.

@Blefish
hi there, can you please give me the exact steps do to so, because im experience the exact same problem.
I've lost the imei in the upgrade process, and them flashed the 4GB image from a user, and then when i try to update to gingerbread, i can't have 3G signal, only 2G.
in the past, i had made a backup of the imei after flashing that .img file, and i think that after update to gingerbread had restored the imei and the 3g was working nice. But this time i cannot acomplish the same, don't remember very well the exact steps that i've made.
I already tried with the B517 and B518, and can't get it to work...
Can you give me some help please?
Thanks in advance

In my case, I restored the full 4GB from some russian community's provided image (it was named Huawei_U8800_FullFlash.bin), which returned my device to stock 2.2. From there I installed 2.3, and everything still worked. The problem in my case was that I could not restore my own IMEI, it never gave me connection & failed to register to a network. The only solution was to use the "wrong" IMEI that came with the 4GB image.
Huawei has some sort of backup mechanism if they think the "data" is corrupted. I can't tell how it works, but it likes to break things that were working before.

i have exactly the same phone than you, because i installed that backup too. After installed it, the IMEI SV is 36, after installing B518 it says it is 18, but before it was 17, and i had 3g signal, but not now.
My question is, wich SV is your phone reporting?
Thank you
I also have a problem like this, but I think it's a bit more severe. My phone got stuck while charging. Couldn't reboot. Was getting stuck on the aurora loading screen(using DZO 5u20). Than reinstalled whole rom. But now I don't any signal and the phone doesn't even see a SIM card. Showing 'baseband unknown' and the IMEI and IMEI SV are also unknown. Not 0's but just unknown. Is this is a similar problem? And can something be done to fix it.
I had some backups on my sd card, untill the sd-card got fried in the phone a couple of months ago.
Hey guys. I know for sure there is another thread about a similar problem but the biggest problem I'm having is figuring out what to do next, or better yet, what did I even mess up?
I made a thread a couple days ago here asking about the LTE option on my phone and how there was none. It's an Intl' phone and therefore I guess doesn't work on Canadian LTE networks.
Before we start, I'm using TWRP 2.7.0.0 . My phone is the UAE version of the D802, which is the D80220C. My current custom rom is Liquidsmooth MS3.2 .
So I found a list of modems and flashed the one for Bell. It was for the D803, but the thread I was looking at said it was cross-compatible so I assumed that meant it's okay for me to flash it on my phone.
Even so, I backed up my EFS partitions just to be 100% sure. I even used the .zip file that automatically backs up the current modem files. So I thought there was definitely a way out if it didn't work.
I will give you the full story of what was done and maybe I can get some guidance on maybe something I did wrong.
1) I flashed the D803 Bell modem.
2) Reboot to system, LS3.2 hangs on start up. Tried a hard restart to see if it wasn't a fluke. Nothing. Still hanging.
3) Figured the EFS files were toast, so I ran the restore .zip for my EFS. Reboot, and still hanging.
4) Said WTF? and restored my first stable rooted stock rom. It booted into the rom fine, but when it got to the lock screen I saw the "Service Disabled" and the phone quickly crashed.
5) Didn't even attempt to restart on that rom. So I tried a couple terminal commands to copy the modems1.img and modemst2.img files to corresponding partitions. Copied both just fine, but no change. Still screwing up.
So, this is where I am so far. I am in the process of downloading the D80220C UAE .kdz file so I can try to flash that one first. If that doesn't work, I'm really at a loss.
When I read into this some more, all I see is people who have totally wiped their EFS files and having to spend a whole bunch of time using a bunch of different programs to get in an recover the IMEI number.
What do you guys think?
Some good news right off the bat. I found a KK baseband for D802 and flashed it. So now I was able to restore my LS3.2 rom and boot into it fine. I see my IMEI and MAC address and can get WiFi at last!
Mods, you can delete this thread if you wish.
Alright so... I got this N900T and rooted it and tripped the knox warrenty bit.
I installed the latest DomPop and read how the efs partrition had some issues and it being easily borked, and well I didn't wanna risk it. Rather than look into how to back it up properly using better tools, I had remembered a command from the S3, su reboot nvbackup, which is supposed to back up the efs stuff to a safe place on the phone. However, upon finishing that command it bootlooped. Well, i then ODINed back to 5.0. my baseband version is unknown, IMEI is unknown, all of the typical EFS is messed up stuff. So i tried, stupidly, the other command to restore the backup, su reboot nvrestore, and upon running that command it forced itself in download mode unable to boot.
i odined back to the 5.0 firmware about 4 more times and nothing happened.
I searched and searched and i tried following http://forum.xda-developers.com/showthread.php?t=2567133, i tried the the script it links to remake the partrition for the EFS.
My serial is still on the phone, i skipped down to the part about repairing the imei. I put my phone in RMNET+DM+MODEM, however it doesnt get picked up by EFS Professionals NV Tools. Any more ideas or help?
Also, is it safe to flash the 4.4 Kitkat without the phone bricking?
If there is anything i cannot do on my computer, are there services cheapish i can send them to and have them flash my IMEI back onto my phone?
Thanks in advance!
Me can not follow
Okay, so I used "reboot nv backup" without first researching to to back up my EFS partitions. Upon reading further into the stuff, I have found that that method destroys your partitions and shouldn't be used. I then, kind of freaking out used the other function "reboot nv restore" which is supposed to restore the backup, but instead it caused my phone to not be able to boot. So I odined back to stock 5.0. I have tried flashing just the modem, I have tried downgrading to NK3(4.4) but that had not helped me either. My baseband is still unknown and my IMEI is still null.
Is the only way to fix this with a UART cable and box? Are there any paid services I can use online to repair those partitions? I attempted to use EFS Professional, however it couldn't talk to my phone, either the SPC Code or the 16 digit security code wouldn't work so I couldn't write the IMEI back that way.

Sorry, I have tried this and it didn't work. Thank you for looking for me.
Have seen many people with IMEI unknown and none of the threads I have read managed to get it back. As far as I know you are now hard bricked, at least regarding the actual phone part of your phone.
The Story
Don't even know where to start. Okay so I have a SM-935W8 (Canadian Version) and it was working perfectly fine running Project Dream rom the S8 one. I decided to flash angelo's Pixel rom for S7 Edge and for some reason when it booted, the network had a cancel sign meaning no network. Once I finished the initial setup, calling, messaging , and data weren't working. Luckily I have a backup for EFS and RADIO in tar, img. and tar.gz formats. So I downloaded the Partitions Backup app and restored the EFS and Radio files, it said successfully restored. I rebooted my device and the issue was still there, no network. So then I installed the stock ROGERS (Provider) rom from SAM MOBILE and it came up with some DRK error and my phone would not boot. So then I quickly used ODIN to flash twrp and then flash Superman Rom (Love it) and use dm-verity bypass.zip to get past the drk error. Then I attempted many other things but to no avail such as flashing the EFS tar through ODIN which caused a "Software Error" and phone to be stuck on a light blue software error screen so I had to use smart switch to FULLY restore the phone back to booting up, then once again I flashed twrp and Superman rom with dm-verity so I atleast have root and a decent rom to work from.
The Problem and What I Have at Disposal
So essentially, I currently have a new section in settings under Connections called "SIM card manager" for managing sim cards even tho I only have 1 slot, it shows that the SIM is ROGERS and LTE/3G/2G in there, but it can't connect to a network and keeps saying Not Registered on a Network. Also, there are 2 IMEI's since my phone thinks theres 2 SIM slots but I really only have 1 slot. BUT HERE IS THE MAIN ISSUE, THE ROOT OF ALL PROBLEMS, the IMEI is reading as "000000000000000" and the IMEISV is "01". Hence im getting Not Registered on a Network. No secret codes such as *#06# are working, keeps giving the Not Registered on a Network error.
I have the EFS and RADIO backups in img, tar, and tar.gz formats as well as screenshots of all my MAC and Bluetooth addresses, IMEI and Serial #'s and all that information. So essentially I feel fully ready to solve the problem but everything I try keeps failing. My EFS restoration says successful in the APP but upon reboot, theres no change. Flashing the EFS through ODIN messes up phone harder. When I use EFS Professional Tool, where do I place the partitions so they show up in the tool?
I used this post to try to fix it: https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516
BUT when I'm flashing the combination through ODIN in AP, it goes to NAND write or whatever and gets stuck, sometimes it gets stuck on Analyzing files or something. I tried every single ODIN version. I really could use some expertise on this issue. A step by step written tutorial, some method anything!!!! Help on this post or even teamviewer or skype for live help would be appreciated. Please help and I'm willing to compensate for successfully helping me fix my issue..
Did you ever sort this out? I'm in a similar situation, except that it does occasionally show my IMEI but also 'baseband unknown'. But still no network access.
i hope i dont risk a warning, but you can use xposed and with root you can change your imei and baseband info.

Thanks, I've done so much to this phone now...
I did try xposed and have tried a different IMEI, it seems like it's a modem issue but there doesn't seem to be a firmware solution - I have tried so many stock roms(All the way back to the first Marshmallow and a bunch in between) and different custom roms too but in the end the error is always there: Not registered to Network.
I saw somewhere in my troubleshooting that some kind of cert needs to be patched because the phone did an update on a modified rom without the OEM unlock being on and then the EFS data was messed up or something like that (all of the research and troubleshooting is starting to blur). It seems like that fix isn't doable without a rather expensive piece of hardware (expensive if your just fixing your one phone I guess) and there isn't any firmware-only fix that can accomplish this patch so I'm stuck again.

Sorry, I should have clarified. I have an S7 (SM-G930W8). I only tried this thread because the issue was identical to mine and I couldn't find anything similar referencing the S7 specifically.
For anyone coming across this thread in the future, although mine was an S7 I think the issue would apply to both. I ended up ordering a z3x in order to use the patch certificate. But it wasn't that easy; the firmware had to be downgraded to marshmallow first which wouldn't work in Odin until I tried just flashing the BL and CP files first, then rebooting and flashing the AP and CSC files separately. In fact, the AP file froze the first time but passed on the second attempt. After that, everything was downgraded to android 6 and then the patch certificate option worked and my s7 connects to the network again.
I'm having a similar problem with my sm-g935w8 Rodgers but has been unlocked. A couple days ago i looked at my phone and it was showing a no signal symbol and I look for my phones information and it showed unknown in all categories, the imei say unknown, and it's not reading the sim. Help me

Sent from my S7 Edge using XDA Labs
Hi Guys
This is my first post on xda even after using these forums for years. But today I cant find a solution on here or anywhere for that fact, and was literally hoping that I've missed something somewhere.
So to start. I have a Samsung Galaxy J5 Prime (SM-G570F). The other day I was flashing a custom rom when something went wrong during the flashing process and left me with a bricked device. Now I did do a full backup before flashing as I've learned the hard way how important this is. During the flashing it also asked me for a full wipe and to backup the EFS. Even though I did do all the backups and wiped everything< I've ticked both boxes and proceeded with the installation. Everything seemed fine but on 99.9% it froze. Not wanting to do anything I left it until it rebooted the phone by itself, where I was greeted with the download/flash screen. Didn't even give the warning about installing custom software and asked to continue. It just booted straight to the download screen. Tried getting back into recovery only to be greeted with download screen. No matter what I did it just kept booting into download mode. So I then re-flashed TWRP. Getting into the recovery I was able to mount EFS, System, Data, etc. Bu all showed 0mb of 0mb available. I then went to restore everything only to find that the SD Card was also wiped by the process. Thinking that maybe the recovery isn't reading everything correctly, I found the SD Card empty in windows also. No call me names or whatever, (I know my own stupidity) but I never backed up my backups on my PC. So I just proceeded flashing stock firmware as to start from scratch. Everything went as planned until the device got reset by odin. I was greeted with a screen saying "installing system update", but as soon as it reach 32% it changes to "erasing" and then "error" with the "DRK Missing" error. Then it boots to recovery where an error message is saying "unable to mount: EFS (Device or Recourse busy). I cleared cache and did a factory reset and it booted the system (Though mount error still appears in recovery even in custom TWRP/CWM recoveries also). Now I have a 00000..... IMEI number and no network connection. I've spent the last week on the web trying to find a solution with no luck. I'm tired AF because I didn't sleep trying to solve this. I tried flashing stock and custom roms, recovery's, boot-loaders, modems. Tried different software's like Samsung Tool, IMEI repair tool, Strings of adb commands, xposed modules, apps, terminals, etc. I even flashed factory binaries with no luck as to how to change it back.
So in short.
My EFS got wiped.
I lost my IMEI.
I don't have any backups.
Been awake for a week searching for solutions with no luck.
So please if anyone knows of a way to change the IMEI, please help me. I know It's illegal to change IMEI (though not in my country). But I down't want to change it for all the wrong reasons. I just want to change it back to the original found on the back of the phone and on the box. This can't do any harm can it? Please I just want my phone back please!

Samsung Galaxy J5 Prime (SM-G570F)
Android version - Nougat 7.0
Baseband version - G570FXXU1BQI6

Hi Guys
This is my first post on xda even after using these forums for years. But today I cant find a solution on here or anywhere for that fact, and was literally hoping that I've missed something somewhere.
So to start. I have a Samsung Galaxy J5 Prime (SM-G570F). The other day I was flashing a custom rom when something went wrong during the flashing process and left me with a bricked device. Now I did do a full backup before flashing as I've learned the hard way how important this is. During the flashing it also asked me for a full wipe and to backup the EFS. Even though I did do all the backups and wiped everything< I've ticked both boxes and proceeded with the installation. Everything seemed fine but on 99.9% it froze. Not wanting to do anything I left it until it rebooted the phone by itself, where I was greeted with the download/flash screen. Didn't even give the warning about installing custom software and asked to continue. It just booted straight to the download screen. Tried getting back into recovery only to be greeted with download screen. No matter what I did it just kept booting into download mode. So I then re-flashed TWRP. Getting into the recovery I was able to mount EFS, System, Data, etc. Bu all showed 0mb of 0mb available. I then went to restore everything only to find that the SD Card was also wiped by the process. Thinking that maybe the recovery isn't reading everything correctly, I found the SD Card empty in windows also. No call me names or whatever, (I know my own stupidity) but I never backed up my backups on my PC. So I just proceeded flashing stock firmware as to start from scratch. Everything went as planned until the device got reset by odin. I was greeted with a screen saying "installing system update", but as soon as it reach 32% it changes to "erasing" and then "error" with the "DRK Missing" error. Then it boots to recovery where an error message is saying "unable to mount: EFS (Device or Recourse busy). I cleared cache and did a factory reset and it booted the system (Though mount error still appears in recovery even in custom TWRP/CWM recoveries also). Now I have a 00000..... IMEI number and no network connection. I've spent the last week on the web trying to find a solution with no luck. I'm tired AF because I didn't sleep trying to solve this. I tried flashing stock and custom roms, recovery's, boot-loaders, modems. Tried different software's like Samsung Tool, IMEI repair tool, Strings of adb commands, xposed modules, apps, terminals, etc. I even flashed factory binaries with no luck as to how to change it back.
So in short.
My EFS got wiped.
I lost my IMEI.
I don't have any backups.

If this problem is still open, then on Your Phone box is writen imei, or take battery out and under serial number there will be your imei, root your device and use IMEI changer grant root access and type your imei in it, after that reboot and your imei should pop up! I had same issue and this steps made my day! THIS WORKS ONLY ON YOUR IMEI, YOU CAN'T CRACK, STEAL IMEI By this method, don't believe those Dumb ****'s from YouTube!
May I help You!
