Hi all, I am a first time poster
I own a galaxy S3 (GT I9300)
first problem...
i flashed a rom called CrDroid and it wiped my EFS and IMEI so i couldnt make or receive sms or calls and got a generic 0049 IMEI
2..
Upon trying to fix the issue, i tried to flash CWM recovery touch and my touchscreen stopped working. so, its a software issue, not hardware
i have tried flashing many different roms, kernels etc but nothing will fix my problems.
is there someone who can assist me in fixing my problems? (flash touchscreen drivers and restore EFS data [in that order])
or
Can someone give me information on how to reflash EVERYTHING on my phone including system and root (and any other) partitions?
i am NOT interested in sending my phone back to samsung or to a repair centre
PLEASE HELP!

thank you so much sir but i can't find the solution to my problem
my touchscreen was not working after i flash by wrong recovery n7100

You'll need a new touchscreen, nothing you can do with software as you've blown the controller.
Dear tweakers of XDA,
I've got a problem with my note 3. After i'd seen the thread for the Note 4 styled S5 Based ROM. I decided i wanted to give Rooting and flashing custom roms a try ( Havn't done it since my S2).
All went well and dandy, i rooted with CF Autoroot knowing my knox counter would trip to 0x1. I've installed CWM Recovery, downloaded the rom and installed it through the CWM Recovery. After install i saw that my wifi didnt work and my 3G Data didnt work which was strange because the regular calling functioned ? Also i installed AEL's newest kernel (because the thread says it wasnt included i had to flash it myself )
After not being able to fix this i'd decided to download ODIN and the correct firmware for my phone, Tmobile Netherlands N9005 TNL version 4.4.2
I flashed it back using ODIN and to my surprise the phone was extremely slow. Reacting really late 5-10-15 seconds later to the sleep/wake button. The lockscreen would also hang for about 30 seconds and the IMEI is unknown. Whenever i open the Phone app it gets stuck. Network doesn't work at all ofcourse because of the IMEI. I do have a backup of my EFS and i'm not too scared of anything. I just really want my note back the way it was
Could you kind people help me ?
if you have a efs back up, so restore it with the original firmware
I used to face the same problem, but i was not as lucky as you - i had no efs back up, and i have to use sptbox - e.g. my original Imei has gone :3
btw, did you face any sensors issues?
There is a efs recovery script in note 3 Android dev thread. Gold luck!

i have searched for several hours now about 12 for a fix and this makes no sense to me so i'm thinking this thread may help or just piss people off idk how forums work any way
after installing this lollipop ROM(link) everything was working perfect very smooth very few bugs almost perfect. i flashed back to unrooted stock after this and now i do not have an imei or a network but i can use my data..... i have tryed the following fixes
1. turn it off and then back on again.....
2. re flash the stock rom with odin
3. use efs professional backup then restore with adb
if i go back to the lollipop rom that i tested i have back the network but my wifi will not work on this rom -.- very confused about what is going on and do not want to risk re flashing the radio if that will brick it
any ideas?
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.

i think i can help you out with that. install that with odin, it should get your efs and imei back:

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
I am having the same problem after installing TGP ROM.

These two threads are the fountains of info :

This one for advanced users who know what they are doing.. it isn't specifically for s7 series but has a universal approach to understand concepts.. don't use the provided drk (prov data) and csc restoring files, they aren't for s7 edge.
Always backup efs and all radio/serial related info firstly after rooting. Good luck

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!
