Managed to wipe my EFS partition while trying to factory unlock my Galaxy S4 SCH-i545.
I had an IMEI of all 0's. I used EFS Pro change my IMEI to match that of the sticker under my battery. I managed to connect to the mobile network again, but this time as data/voice roaming. I have also backed up my /efs folder to my SD card. I used ODIN to use a .PIT file to repartition, and a stock Galaxy S4 image to do a full factory restore. I then re-rooted and installed CWM using the I545 All-In-One Tool. The phone was then in Factory/Test mode. I used Rom Toolbox's Root Browser go to /efs/FactoryApp/factorymode. I then changed it from "OFF" to "ON," removing the Factory Mode display after a reboot.
However, I am still unable to get 4G, still data roaming, and still unable to use the phone as I normally did. I no longer have a copy of the original /efs folder, as it was lost during the ODIN restore. Any way I can restore full use of my phone?

I'm in the same boat. I didn't explicitly delete my EFS partition. I simply backed it up using Hyperdrives Aroma prior to installation. My phone has these connection issues also. Are you certain EFS is responsible? I'm not sure how I managed to corrupt it with a backup. Moreover my IMEI wasn't reset. I can't find the backup on my phone either. Was on the phone with tech support for an hour last night to no avail. Please let me know if you figure out how to fix it. I'll keep you posted as well. I just order a new sim card

Currently working on a way to use another phone's /efs folder, after the proper modifications, in my phone.
I did this. Do a factory reset through settings menu on phone. It reset and bingo

found a solution ? got same problem
Since my original post, I have obtained a copy, obtained via dd using ADB while the phone was in recovery. It has not fixed the issue. Rather, the IMEI was again reset to 0 after the restoration. Getting a new SIM card has not helped, either. I'm about to restore everything using an ODIN image to complete stock, and send the unit in for repair.
EDIT:
Here are the things I've tried so far:
I have also tried flashing the ME7 radio firmware, to see if that could do something. So far, nothing.
I have edited the serial_no in the efs folder, no luck as well.
I may restore the bootloader to factory, and update to the ME7 build to see if that can fix the issue.
Restored mmcblk0p10, mmcblk0p13, mmcblk0p14, and mmcblk0p15 with clones from known-good devices obtained via dd when the phone was in recovery.
Used DFS to push a PRL and change the IMEI to the correct one.
Tried EFS Pro to restore an EFS backup made from another phone.
Repartition via a PIT file.
Factory restore of VRUAMDK via ODIN.
Flashed VRUAME7 radio firmware.

I've had that app. Was yours a Verizon S4? What did you change to fix it?
bump. anyone have any advice?
EFS problem?
I'm not sure if I'm having a similar EFS problem...
I factory restored then rooted with the all in 1 kit. Periodically I see a message and big red X that says "please install sim card"
I'm getting a terrible delay from hitting call to when it actually connects - sometimes it won't connect at all. I have to reboot phone to get voice calls but data works fine, which makes me think its not EFS...
sound familiar to anyone?

By ruling things out, I can focus on other areas.
Since that didn't work, it appears the purpose of the post and its title are merely to give your life meaning...

I thought you had already eliminated the EFS as an issue. It sounds like you need a new SIM card. My phone did that before I received a new one
EFS Problem here also
I have a similar problem. I can surf the web in 4G and on Wi-Fi, but when I attempt to make a call, I get "Service Unavailable" and all my inbound calls go to voicemail. So, no voice calls for me. I called verizon, and they gave me a new SIM, but I still have the same issue.
IMEI and IMEI SV match the back of the phone:
Fix:
> Settings > Accounts > Backup and reset
> Factory data reset
i restored back to stock. verizon sent me a new sim and refurb phone.
installed the new sim in old phone and it said could not activate...
thoughts?

Restoring back to stock by loading the original image (unrooting) did NOT work for me.
Restoring to defaults via settings cured my problems.

Bumping for any help anyone can provide...
Odin packages do not fix the efs partition. The efs partition is where the phone's information is stored. Like your unique imei number. Without said number the phone cannot be activated at all. There are paid services available that will fix it for a fee(Don't pm me... You have Google. Use it)
You can try to do an nv data reset but I doubt that will work either because that relies on the idea that you just messed up something in your NV data and not fully deleted the partition.
To do nv data reset you need to get into your touchwiz hidden menu. Can't access hidden menu? You need to enable it(Google).
Hidden menu is huge with tons of submenus. I won't be walking you through any of it specifically. But here are some dialer codes. For more... Google.
*#06# shows if your IMEI is still there
*#1234# show hardware and software version
*#*#4636#*#* test mode. Set preferred network mode. Enable disable radio. Change band. Etc
*#7780# and *2767*3855# factory reset
*#197428640# and *#0011# and *#9090# and *#2263# and *#27663368378# service menu (through this you can generally access the entire hidden menu by hitting menu button and selecting back until you are at the root of the menu)... Navigating said menu is on YOU.
*#2263# rf band select
*#7284# UART MODEM PDA selection
Not trying to be giant **** or anything but that's why there are EFS warnings&posts. Also why some root users shouldn't really have root( / ) access.

I'm in a similar situation.
Empty EFS folder (No Backup)
Because of this it is stuck in Factory Mode.
I was able to freeze factory mode through TiBu but the only things i haven't been
able to fix are my lock screen and power menu. (no lock screen/power menu)
I've tried every fix i was able to dig up on here but no luck. :\
Any suggestions would be appreciated
Hi I'm looking for help with my i9300. I had an aborted root, the phone froze during root and eventually I had to restart, I was able to re-install the stock ROM and the phone seems to work fine, apart from one major problem: It won't recognise any mobile networks. The phone won't recognise my network (3), or simcards from any other network. I have re-entered the APN information manually, but this has made no difference.
All other aspects of the device work fine, wifi, apps etc.
I'd appreciate any advice on steps I can take to resolve this.
I have obviously tried standard stuff such as full factory reset.
The phone still displays coverage bars as if it was connected to a network, but when I try to dial out or send messages I get an error message "unable to register on network"
Check the imei number matches the one under the battery, if it has changed then you have major problems without a backup of the efs partition. Search and read for hundreds of similar threads, there is a sticky in the general forum.
Before I start with the issue, let me begin with some basic information: This is in regards to my Samsung Galaxy S5 SM-G900T (T-mobile), running Lollipop 5.1.1, FOG6 build, DOB1 baseband, rooted, deodexed, but otherwise stock.
My problem: Today I flashed a rom via Mobile Odin Pro and soft-bricked my device. After a lot of hair pulling and screaming at my phone and computer, I finally got my phone up and running again. After trying many different solutions, I eventually tried re-flashing TWRP through Odin (recovery initially would not boot, hence the soft-brick), which succeeded, and then recovered my phone by restoring from a previous backup.
This got my phone up and running again, but once it boot, I had no service. I first checked my APN settings, but was presented with a message stating, "Unable to view the access point name settings. Access is restricted for the current user profile." I tried adding a new APN, but once I added it, it did not appear in the APN list, which continued to only display the above message. I then tried to "Search now" for Network Operators, but nothing was found. So next I checked my IMEI through "About Device", and discovered it was set to "Unknown". Checking the IMEI through the dialer (*#06#) lists the IMEI as "null / null".
I have searched high and low and tried everything I could find to fix this. I tried restoring my TWRP EFS backup to no effect. I also tried flashing the modem through Odin, as well as restoring my TWRP modem backup. I tried using an Xposed app to manually set the IMEI back to its original value (I happen to have my phone's original IMEI number written down from when I SIM unlocked my device), but while this updated the IMEI displayed in the dialer (through *#06#), it did not change the value in "About Device" and did not restore my service.
The last solution I tried (found here: http://www.technobezz.com/restore-galaxy-null-imei-and-fix-not-registered-on-network/) involves me using the dialer to enter Service Mode to make some changes; however, while dialing *#197328640# did open the Service Mode menu, the menu was totally blank.
Please help! Given the current state of my phone, I cannot make or receive calls or texts or do anything else requiring a mobile connection. I have looked everywhere and I don't know what else to try :crying: :crying:
Assistance in this matter would be greatly appreciated, as until I am able to fix this, I don't have a functional phone
Any suggestions?
I bought a new Lenovo A806 (original version android 4.4.2 - build VIBEUI_1432_ST_A806).
There were lots of Chinese writings imbedded in the rom and apps so I rooted the phone and tried to disable some apps and stupidly removed the stock phone dialer and contacts. Then whatever replacement app I tried from the Google play store did not work.
The replacement dialer gives me the message:- “You have removed/disabled Stock phone application, its required to properly functionality.” (pardon the Chinese English)
The phone cannot read the sim card and the IMEI number has disappeared. Following forum advice, I installed “mobileuncle” but cannot insert the IMEI number manually. When I go to Engineer mode, CDS information and try to go into Radio information, I get the message - “Unfortunately, Common Data Service has stopped.” So I cannot even go into Radio information.
I researched on the internet and tried to change the Rom. I installed the required version of TWRP recovery and after trying a few Roms, I managed to get Version VIBEUI_V2.0_1508_7.85.1_ST_A806 installed.
This version behaves better but still no IMEI number. Instead I get a different message – IMEI invalid.
When I try to call, I get this message: - “To place a call, first turn off Airplane mode”
But Airplane mode is off. But at least the dialer seems to be working and I am able to add contacts.
And I can get to radio information from mobileuncle with this version but when I type the IMEI number after the ST.., I get the message: “This command is not allowed in userbuild”
Even with a space between the ST and +, it still does not work and I get a different message, “at command is failed to send” I even rebooted after inserting the IMEI number and still no joy.
However, the wifi seems to be working on both above version and this.
I have a backup of the original corrupted rom so if anyone has a solution for either one, please help.
I installed the rom’s through TWRP recovery which is on my phone. I press volume and on/off buttons to enter into this.
I tried to install a flash tool and all the required drivers on my computer, I am using windows 10. I cannot seem to get the flash working.
Fixed
I managed to get the "SP Flash tool" working on my Windows 10 computer and that worked. Everything fixed. Thanks.
This afternoon the signal on the phone was lost. There is no way to recover it. I have flashed the ROM again, restored, changed the kernel and remains the same.
When I try to call it says "Disable airplane mode" airplane mode which obviously is not set.
I do not know what to do.
My SIM works well on another phone but other SIMs do not work on mine.
Thanks.
I followed this and don't work:
