Im not sure were to put this so called tutorial so mods feel free to move it to were it belongs if its not supposed to be here. I was having a big issue with my Samsung i997 thats was showing no baseband on settings, No imei null/null and of course didnt have any signal. I started a couple threads about things related to that. No luck, until a member called Truckerglenn pointed me to a efs .tar file he had made that fixed his phone.
So before i start, credit for the efs file goes to Truckerglenn i had nothing to do with that. Then, i want to make this clear, This worked on my i997, it doesnt mean it could work on other phones but for some reason i think it will. I messed up mine on purpose a couple times after i solve it just to see if it was a real solution or just luck. It worked every single time like a charm. With that said, i got to make clear i didnt have a copy of my original efs file. I have deleted the efs file a couple times also. So i think none of you could mess a phone worst than i did, and i still managed to bring it back to life using this method.... So lets talk about what i did:
First download Truckerglenns efs .tar file located here:
http://forum.xda-developers.com/showthread.php?t=1438113
In my case i used the infuse unbrick ODIN file so i dont know if it works with any other firmware or not.
Open the ODIN file located on the infuse unbrick files and click efs clear, yes i know it sounds very risky and people have made clear that is not recommended but hey, you cant mess up your phone worst than you already have so. Anyways, put the infuse ODIN files were they belong, pit, pda and phone. Then here comes the tricky part, i used the Truckerglenn file in the csc box to flash it with the unbrick files.
Click start and the phone will flash the stock Froyo for the i997, wait until the flashing ends. Then when the phone reboots into recovery before hitting reboot go to wipe data/factory reset and click it. Then you can hit reboot phone and if youre lucky enough you will have your signal, restored imei number and baseband version.
Like i said this worked for me and i cant asure you it will work for you. But after all those weeks i spent dealing with this without success and having deleted efs many times and messing the phone that much, i didnt have anything to lose. Also thank Truckerglenn for his efs if this work on your phone, after all im just giving you an idea on how i made it work on mine but i didnt create a file or anything i just flashed it the way i just told you. Good luck guys and keep up the good work!
this happens to me as well, but flashing an efs didn't help me. any other ideas?
Step by step??

So, I am having same problem as u were. One thing that I want to make sure is do i clear efs and then flash ?? or just click the box on the efs clear and put everything and flash it??
So here is first option - You check on the clear efs box and then click "start". After it's finished, put other files and click "start" button again.
Here is second option - You check on the clear efs box then put all files and click "start" button and done.
which one is correct way to do this process??

It's been a while now, but if I remember the Clear EFS box was checked, so go with option 2.
But hey, right now your phone is 'FUBAR'. Try different settings if one doesn't work, maybe another one will.:good:

Ok, my phone got fixed by AT&T. But it wasn't software problem. My radio chipset was burnt. I checked and when AT&T saw that, they just replaced my phone to new one. For free. Pretty happy now. Thanks for help tho
Thanks!
OMFG...I bricked my Infuse a while back and I thought all hope was lost. I have bought a Note since then but I wanted to sell it and wait for the Note2 while I could still get a pretty penny for it.
This worked like a champ.
I basically followed your instructions using the Unbrick package here:
http://forum.xda-developers.com/showthread.php?p=27286083#post27286083
I also checked the EFS clear checkbox. I didn't have to factory reset from recovery either. It just rebooted and I popped in my SIM and it worked!
So I haven't gotten to the stage where I do not have signal... but do plan on moving my infuse from 4.0.4 to 4.1.1. Through this process, it has been noted that you could lose efs. So before I tried to install the rom, I backed up my efs through root explorer. Within this app, all I did was copy my whole efs file and pasted it to my SD card. After this, should my efs be fully backed up? And if I were to install jb and WERE to lose signal, how would I go about restoring it? My efs is on my internal storage..
Thanks

I was having the same problem. What room are you on/trying to go to?
I was trying to flash slim bean beta 2 and encountered the same problem.
I Odin back to stock, flashed cm9, flashed Beta 2...
Loss IMEI...
My solution was to flash CM 10, THEN flash beta 2.
No problems since then.

@TokyoLee
It would be best if you informed us of the upgrade path you took.
Slim ROMs (I am assuming you are trying to flash a JB 4.2.2) are known to cause loss of IMEI if flashed directly from ICS. Best solution would be to flash a CM10 and then a CM10.1 before flashing SlimBean. I have followed this path and have had no problems although I have gone on to Rootbox 4.2.2.
scott.hart.bti's Unofficial CM10.1 post has instructions for the proper upgrade path, see here: http://forum.xda-developers.com/showpost.php?p=28842232&postcount=1
andros11's "[Guide] How to Flash Jellybean" here: http://forum.xda-developers.com/showthread.php?t=1878458
is an essential and important read to avoid any IMEI snafus.
Also, and this important since almost every JB ROM thread mentions it at one point or another: REMOVE your external micro-SD card from the device before flashing a JB ROM.
Hope this helps.

You may have to start fresh from GB [or Froyo]. That would be the best recommendation.
qkster's posts are valuable in how to get back to GB. See here: http://forum.xda-developers.com/showthread.php?t=1524081

Unless you have your EFS backed up which you can flash via ODIN or Heimdall it is impossible to get tour IMEI back.
Best is to go all the way back to GB.

Do not even think about doing such a silly thing. This is an Infuse specific efs. You cannot flash it to the I-9000 or I-9100, for example. The partitions are different on different Samsung phones, they are not necessarily interchangeable.
Unless there are clear instructions available, you could end up with a very expensive brick.
Hello guys,
I just installed 4.1.2 Android from 4.2.2 and now My phone can't read my SIM card. When I'm trying to unlock my phone with GalaxSim Unlock it says "Warning: invalid IMEI. Restoring an EFS backup before unlocking is advised." The IMEI code on *#06# and on my phone's box are different. I have no ideas what I can do because I have never had this problem before after ROM installing. How I can solve this problem?

thats the best way (link in above post) if you happen to of installed synergy rom at any time it would have asked about making one for you. also nandroid manager can backup it also so check and see if any of your nandroids have a efs partition saved. if not read post in link more than once before doing anything.

You need to reread the directions in the Comprehensive IMEI thread. You'll see why it's failing. I will say this though, "adb" is primarily a computer command so it's unnecessary on mobile.

I'll ask you this now before I explain to you the command, does your IMEI in Settings/About Phone match what's on your Verizon GSIII retail box? Cuz restoring your IMEI will not work right now if its the wrong one. What you just backed up could be the "broken" IMEI and restoring it will do you more harm than good.

Aight, second question. Are you absolutely sure that you have a Verizon Galaxy SIII (d2vzw aka SCH-i535)? If so, proceed to read.
if you just performed this IMEI backup with the improper IMEI then the restore command will only reinsert this same wrong IMEI. You want your "proper" IMEI which is on the box to be backed up before you ever attempt an IMEI restore. If you have a CWM or TWRP rom backup then you should try restoring that THEN check if your IMEI is correct or wrong.
Do not post your proper IMEI. If it returns if/when you restore your rom in CWM or TWRP then just say "my IMEI is correct" or something like that. If you don't have a CWM or TWRP backup or don't know what I'm talking about then you're going to need a Windows computer and you'll need to Odin flash stock VRALF1 or VRAGL1 firmware tar. Make sure to unzip the file before using Odin, Odin flashes "tar" and "tar.md5" files only. If your IMEI is not restored at that point, then you'll need to reprovision your LTE sim card with the following code. It will erase your phone's storage. The dialer code only works o ICS software (so you'll need absolutely need VRALF2 or VRALG1):
Open the dialer and enter *2767*3855#
I'm stepping out for an hour or so. If you have any questions, hopefully someone else can provide input. If someone else things what I wrote above is unnecessary, please say so.
Edit: For clarity as well, I do not know if the VRALF2 or VRALG1 tar files format your internal storage (let's reasonably assume they do wipe /sdcard), so backup whatever important data you have on the phone to your computer or external sdcard.
Actually I have got SGS3 i9300. When I created this thread I didn't see that here is a subforum for i9300. Thanks for the help I will try it and let you know.

I'm actually considering doing this today. I lost my IMEI/ERI and restored them with the forbidden software but the problem I'm having is on some roms my google play store won't connect and it's been kinda frustrating and I don't know what else do, I've cleared store cache and data, plus every other fix I could find online. Plus it might be good practice for me if I have to send my phone back in the future as I bought my S3 rooted and unlocked.

I'm off today and not really interested in the football game tonight so I got time.

This was before I found the Samsung Repair Utility so you may not need QPST and you can just use the repair utility.
1) I restored my IMEI using this guide here: http://droidmodderx.com/galaxys3/?page_id=79
2) Please note that since I hadn't found the repair utility you may not need to do step one, the repair utility does both IMEI/ERI
3) Go here: http://forum.xda-developers.com/showpost.php?p=44871571&postcount=3
4) We don't want to get XDA in trouble so I can't link the repair utility or have a mirror for it. I can only put you on the block and you have to find the house....
5) Once everything is ok flash your modem back up to whatever current modem you were using.
6) Also it may be best to just Odin back as I'm having issues with Play Store on certain roms.

Hi there,
After reflashing stock ROM 4.4.2 because a failure with custom ROM, my IMEI now is 0
I know I can restore it with a pds.img, but I haven't one, how could I get my phone work again?
Thanks
Bump to this thread. Could someone help me...? My /pds folder is empty (at least that's what CM File Manager says), I have no backup, and my IMEI appears as "Unknown"...
I got the same problem. No solution yet :S
Have you tried fastboot flashing the stock firmware to see if that helps?
Probably a long shot.

Why fastboot? What's the difference between it and CWM?
I flashed stock radios today. No luck. Last thing to do is flashing stock, because I've seriously tried everything...
Is there a way to manually input the IMEI in the /pds folder?
Nope. I've already flashed about every rom, factory reset it, etcetera. Even struggled around with hex editors and stuff but the problem is that it's forbidden to 'change' imei so it's kinda hard.
Some dev has to look for a opportunity to get the imei from fastboot (mine shows up there) back to the pds folder or somewhere else..

OK, I downloaded a stock ROM from here, and I followed the instructions shown in this post. I can't believe the motherloving crap worked. I HAVE MY IMEI BACK MOTHERLOVERS!!!!
I HAVE IT BACK!
I just want to tell you guys I was able to isolate the cause of the problem. Maybe someone could find it useful.
The whole problem was because of the kernel I was flashing (this one). There are two versions of that kernel for AOSP ROMs: a standard one and an ANYKERNEL one. Flashing the first one made my IMEI 'unknown'. Flashing the ANYKERNEL one solved the issue. The ROM I was flashing the kernel in was Gummy.
Really strange stuff since it had never happened to me before...

Its not an issue as I see it. I have made anykernel zips because of this purpose only, some ROMs use different type of ramdisks which cause other developers to not support them at first place. I made anykernel zip for such ROMs so that my kernel can be used on any ROM without any issues. I hope it answers your question.
After numerous reinstallations CM and other roms I caught a strange bug.
Now I is not working WiFi and BT, fm radio. it does not matter at what firmware. on miui or custom rom. also after the installation of any version of miui version puts custom it is not work... black screen(
MAC address blank in the information about phone.
Are there any ideas how to deal with it and how to fix the phone?
I use fastboot and twrp for install rom. not use mi recovery
to @sharan.nyn There is a special version of tvrp that makes backups of absolutely all partitions. You can do it and send me?
Can you tell me how to take backup and what exactly will be the file size. I think it would big files.

Yes, they are big, but probably can not backup such as the cache systems date. then the backup will be small.

Make a backup without system, Dalvik cache, data, cache. Maybe he will not be big, and you can upload it. I have no one else to ask.
Where did you get the recovery image? And is it compatible with our device? I think it must be compiled for our device for it work.
This changed magdag twrp recovery. It is fully compatible. it makes a full backup.
backup size ~100-150mb without system cash data dalvikcash

Sorry dude I didnt get a notification for the quote. I have backed up. It was about 30 partitions and its 380MB. I'll try to upload it ASAP and send you the link.
Update: Haha compressed it with winrar 5. Used the best compression and got it to be 30MB.

I would advise you not to flash ALL PARTITIONS of one device on to another. This is due to the fact that it includes EFS partition which is unique in a way that it contains your IMEI # and other details which are unique to every device. This can brick your phone permenantly. A flash without ESF partition can be great.
Good luck !
Usually BT, WiFi, Radio trouble occurs it you have messed up with your motherboard hardware values. Try going back to the ROM you were before on and make sure you haven't flashed any wrong radio for your device. ( like your radio was meant for India and you flashed China or any other firmware. )
Do quote back in case you expect an answer!
after installing a full backup does not run the sim card. If you load Fail ESF from its own backup, the SIM card is starting to work, but the WiFi did not work. From this it follows that mi4i imei stored somewhere else and booting phone compares it imei. The question is, where are still kept IIMEI files?

I have a similar problem to you : after a hardbrick, my IMEI files are uknown. How did you manage to install the backup given by sharan.nyn ?
BTW, when you backup the EFS with Mi4i toolkit, two files are shown : /dev/block/mmcblk0p20 and mmcblk0p21. I don't know what to do with that, but I'm pretty sure they have IMEI in them.
i am facing similar issue but my sim is not detecting on first slot but it is detecting on second slot
even my imei is showing correctly should is go for replacement coz i bought it few days back
Actually I bricked my device and I was trying to flash the stock ROM again using SP Flash tool. Unfortunately while flashing it shows sec_aut_mismatch ( or something like this) for the file called cust.img in the stock rom and says please disable verified boot. What I did now is "why don't I try letting it go?" I unchecked it. I flashed rom without this file. it got flashed, works fine everything except SIM Cards. The phone detects sim cards but no signal. SIm cards are fine Physically. Do you believe that this not flashing cust.img could be a cause?
MAIN THING: Flashed Stock Rom without CUST.IMG
Secondly I tried to flash the cust.img using fastboot now, but still no luck. I don't know what this file does. PLEASE HELP ME. I AM IN TROUBLE
That's most likely an EFS problem. Do you have some backup?

I have a little backup taken through twrp. But it has only some files starting with boot, bootloader and recovery. Total 9 files. Can you explain more about EFS please?

A thing I forgot is that cust.img flash is successful in fastboot mode

EFS is something responsible for your IMEI which is connected to the signal and SIM.
You cannot have phone signal if you don't have IMEI number which you could have lost. Can you check if you have IMEI? If not, the problem is probably in modem and I would be happy if you had backed that up.

I don't see any IMEI numbers. A little research tells me that I must have nvdata.bin and nvram.img in the backup. If this is correct then I don't have such a backup. Is there any way to fix it up without backup?

One more thing I notice is that when I enter Recovery mode, It says "nvdata corrupt" in red. More information you may want to know is:
My device is redmi 6a
Wifi works fine
Baseband version present
When I insert sim cards, it detects them(icons get updated on the notification area) it also says getting sim info.
When I enter phone information, it says signal strength in those numbers when sim is inserted
I believe that hardware is fine thus. I really regret my step of trying to change OS. I just want to get sim working somehow

I have never had that kind of problem and only had problems with EFS.
I think flashing stock ROM would fix your problem. I don't know what else could be.

You should know that EFS ( NVRAM ) is a partition on your Android device that stores all the important data associated with your phone. For instance, these data include the IMEI number, Mac address of Wireless devices, important files of internet and product code, etc. Moreover, this data is so important that without this, you would not be able to use your Android phone. And it is very important to keep this partition safe and backed up in case things go south.
My guess is because you were flashing custom ROMs and/or modded apps that you have lost this important EFS ( NVRAM ) partition on the device.
