Restoring imei and efs on an unbrickable infuse?

Hi, the title says it all. Is it possible to restore imei and efs on a samsung infuse with unbrickable mod applied? Or unbrickable mod only possibility is to reflash the firmware? I mean i know that unbrickable mod is used to be able to get the phone on download mode but. Is it able to flash something to fix imei? Because i have tried just about everything to restore my Infuse imei with no luck. I know there are advanced tools to do so, But i was curious since Unbrickable mod go so deep in terms of changing that sequence i may be able to repair my imei somehow with it.

I posted an EFS repair file sometime back. It's either in a zip or a tar.

Do you have an idea on where is the file located(what thread)? My imei shows as null. I guess ill be able to fix it with that file right?

By the way, pretty cool to find another old school guy in terms of pcs. My first computer was an atari 400. Had a lot of fun with machine language and basic also. Every time i managed to draw a simple line with commands or maybe just saving programs using an old school tape recorder which was the old version of what we call cds and dvds nowadays ha ha... Oh that brought me some memories ha ha

Hey Truckerglenn, sorry for bothering you but i went thru every post you have made(all 19 pages) and i didnt find an efs file. Maybe its been deleted or something. The only thing close to that issue i found is the Restoring a dd backup with Odin (A fix for a badly broken EFS) thread but no file there. Maybe you can help me find it

Nevermind Glenn, i already found it. In case someone needs it heres the link to that thread:
http://forum.xda-developers.com/showthread.php?t=1438113

Didnt worked for me, but maybe some lucky guys will be able to fix theirs with that file....

Sorry that it didn't work.
If you had an Atari400, then you'll remember the Happy boards that we used to put in the old 1050 drives. They made such a racket, but you could copy any copy protected disk.

Hey Truckerglenn, finally i managed to make it work!!! Wohoo! Im very happy, So when i was going to give up, i decided to give it a try again and heres what i did for the rest of the forum in case they have the same situation and want to give it a try:
I openned ODIN and clicked efs clear, I know its not recommended but i didnt have anything to lose so, I used the infuse unbrick files to take it back to FROYO, pit, pda and phone. Then i use your efs file and dropped it in the csc box. The phone flashed. And when it went into recovery i gave it a factory reset and rebooted. When it turned on Make shure enough it looked like nothing happened. But a couple seconds later the phone did have its signal and the baseband version was back also. I know its weird, but it worked for me. So if you have a phone showing no imei and baseband unknown why not give it a try??? You could not damage it any further than you already have!!!!!!!!!!!!

Great glad it worked. It'd been so long, that I'd forgotten the steps that I used. But now that you mentioned it, I do remember having to wipe the efs from within hemidal or odin.
I'm planning my escape from the digital world!

I'm glad you got this sorted out, enelyam.
I'm gonna post a link to this thread in the HOW TO thread I started so it can be reference for anyone else later.
Thanks for posting your results.
Add a [SOLVED] to your thread title so some other unfortunate soul (not wise enough to have 10 EFS folder back ups like me) who borked their phone later can find it too.

Thank you all got my imei back.
I have already hit the thanks button but felt compelled to write it here as well.

I was really hoping this would work for me, but when I dial in *#06# I get a "IMEI NULL/NULL" pop up. Any other ideas that could possibly work for me? I really don't want this phone to end up being just a music device.

didnt work for me either

[Q] What causes a phone to lose it's IMEI?

What are the reasons a phone lose it's imei number WITHOUT ROOTING?

Phones cannt "lose" their IMEI

Lost IMEI of Samsung Galaxy S i9000
I also want to know why device loses IMEI.
I bought a Galaxy S i9000 from US, rooted it and flashed CM 9 on it. After that it stopped showing IMEI number.
Anyidea why this must have happened ? and How can this be fixed ?
After that

I find it disturbing that you're willing to throw out such information without doing research on the matter first.
To address everyone's concerns more accurately, depending on the model of the phone, the IMEI could possibly be stored in a special partition as is with the LG-P925/P920 (a phone I own and HAVE lost the IMEI on before with a bad flash (came up with incorrect IMEI, had to manually re-program my phone)). If this special partition becomes damaged in any way, it can result in the loss of the IMEI and service. Also a possible problem is a radio firmware (aka baseband) that cannot read and understand the current formatting of this special partition, thus rendering your IMEI unreadable to the phone's current software. However this is easily fixed as you will just need to have a new baseband programmed into the phone that CAN read the partition which would then restore service.
If it appears you've lost your IMEI information, I would highly suggest the following: First, flash your phone BACK to STOCK. See if it's restored, then proceed from there with accepted, tried and true steps to flash your phone to a custom ROM, and follow the directions provided to the "T". If this is not an option or does not work and your IMEI information is still not showing/invalid, you may wish to post in a relevant thread or start a thread in the forums for your device model in order to obtain more detailed support.
If you have not flashed the phone or done anything special with it, but the IMEI appears to have been lost, this may be damage to that partition for some reason, though it's highly unlikely. With flashing a phone, typically it's a newer baseband that does not work with the phone that is the reason for this information loss, but as with the OP, if he truly has not flashed the phone and is 100% stock, it may be either a corrupted partition, or failing hardware, either way, in his case I would recommend a reflash to stock (out of the box), and possibly a trip to the local carrier store for support.

The phone doesn't lose its IMEI, maybe a root needed app change it.

So it's not lost. As you even said it could be a damaged partition, or some flash that makes the IMEI unreadable to the phone's software.
But not "lost." Thus why I quoted them in my post. Want me to pull up dictionary.com for you?
I was trying to tell OP to rephrase the question because he was being very unclear. He may not even be talking about what you just said, your story on your phone.
No need to put an icy edge to your voice "throw out information without doing research." This is actually rather offensive for immediately assuming I'm spewing out lies to the OP.

Not saying you're lying, however you didn't offer any idea as to why it would disappear. Yes, the IMEI can be entirely lost as in my case (all 0s as my partition became completely corrupted and unrecoverable, and then a completely new random one which had to be reprogrammed after I managed to install a new copy of the partition), but it requires special circumstances. In his case, it may or may not be "lost" but you did little more than offer him a cop out answer without giving him all the information available. If he's asking a question, he obviously wants information and to learn, and I am not for withholding information or providing half-truths. Flat out telling him that it's not "lost" is a half-truth as we do not know the full extent of his situation, and in instances like this, it's better to provide him with more answers than not since we don't have all the details. If he would reply and explain what happened, we could be more definitive, but as it stands, giving him both sides of the coin is more beneficial. TMYK
At this point, I'm exiting the Q & A section, this is exactly why I don't hang around here. Yes, I'm "icy" but I try to be as warm and helpful as possible and yes, I step on toes a lot, so I'm just going to show myself the door. Good luck OP with your IMEI issue.

Maybe the flash tool
Brush tool can clear the IMEI,perhaps you use this tool

Read the Q&A section of the T-Mobile Samsung Galaxy S4 (SGH-M919) forums. I learned by reading the forums, you can too. I will reply no further than to provide you the following link.

Clones Phones Or Orignal ??

Hello there! I have a Samsung Galaxy Note 4, and all of the sudden it said mmc_read failed, Reactivation Lock: ON, QUALCOMM SECUREBOOT: Enable (CSB), Don't turn off target, etc..
I went to Vodafone's shop where i bought and they told me to simply try the factory reset. I did it and now appears to have lost it's IMEI and all basic info that it's needed to function from turning on to installing a latest firmware for android.
All jokes aside, my cellphone seems ready to hit the grave. Any help or tip is welcome

[Q][N8020][IMEI] discharged battery and IMEI: null / null. What I supposed to do?

Hello.
I have Samsung Galaxy Note 10.1 LTE (N8020). My device battery goes to 0%. I turned on device and I have charged battery.
I noticed that there is 'no service'... I checked IMEI and there is 'null / null' :/
I performed full wipe, flashed with boot+pda+modem+csc - no change.
Now I have XXBLL2 pda with root, imei on paper and 'no service'.
What I supposed to do?
Please help..
Regards.

Hope you did not flash any custom rom check the count if it is zero take it to a service center get it replaced

Run Triangle Away to reset rom counter .
Flash stock firmware and then factory reset to clear reset status from modified .
Otherwise its a no warranty job if Samsung spot its been customized or rooted .

Mate, instead of using the recovery above and as your tablet will still be in warranty, TAKE IT BACK as long as you have restored stock.... You could go through these steps and still find you have no IMEI, need to take it back anyway. Why screw around with it more and chance Samsung charging you for replacement parts?

I can do what I want with this tablet and still it can be repaired in the service, but it want to do it myself (before xmas).
I can flash / root etc. Simple question, it is possible? Can I for example take EFS folder from another tablet, and change IMEI or something like that?

ah, I did't know. ok, so... xmas with 'no signal', and then I will take it to my samsung friends
Thanks all for help

Sounds like your EFS stuff has been fux0red somewhere along the. I'm thinking maybe there was some custom ROM flashing going on in its recent past? I've come so very close that 'oh what's the worst that could happen' moment myself mostly due to feeling like I'm the only person on the planet that has a lte vetsion of this device. N8020 just doesn't seem to have any development dome yet... anyway back on point...
Unless you have a back up of the efs partition its not something you can flash away and so will need warranty repairs or replacement by Samsung. You could try for DOA with the provider you 4ot through if its inside the timeframe, its either 14 days or 45 from memory but that's something that could backfire if you get a tech savvy sales person and the bust you. The first few posts are talking about making sure if you send it straight to Samsung that they don't bust you by the inbuilt flash counter. If they find its been flashed or the counter is >1 they will NOT cover it under warranty and you will be up for costs to repair. Can get a little expensive so best to be 100% this is sorted before submission. Ignore the poster above (mags69).. they must have not read the posts in full and are basically sending you to the wolves...
Search efs from I9100, I9000. Any of the note handsets 7xxx or whatever to learn why its so important to be sure you have that backup before going crazy. Worth a poke around in the file sysytem too IMO.. most,>90% from what I've seen, custom anythings flashed in cmw will do the backup by default. Seen it in folders, zips and nested deep in the sir structure. Like /mnt /sdcard /revo. Or /mnt /sdcard /checkrom/backup and so on.
Sorry for your troubles too mate.. sucks I know but with a calm and steady approach you should be able to come back from this with a lesson learned. Calm and steady and lie your ass off to Samsung
EDIT: maybe try a different modem. Hell its not going to make thing worse at this stage provided you don't hard brick your device somehow but obviously a lte stock modem would be the winner to try. Long, long shot though... worth the time to be sure on the other hand. I bet the efs at a different block address in the rom on these Ltd ones though and so its been overwritten or whatever cause the update has been coded to write at a specific block that's fine on say wifi version but due to the software differences on 3g or lte ones.

ok. I'm Samsung employee so I can repair it in service any time
I have another N8020 with proper imei but I don't want to have 2 devices with the same imei (its possible? I think no )... changing imei is illegal - I know, but I want to change it to original one.
The best thing - I use original PDA very long time... Without any flashing etc (never custom pda), I was a happy user and what? I loose IMEI xD
I take it to service. Too much combination = brick...

Modem can fix nothing it does not touch EFS .
CWM flash does not always backup EFS so don't rely on that read the description .Tools are available to back up EFS folder .
Occasionally flashing a stock rom/ factory reset may repair EFS but not if no EFS folder .
XDA forum member ODIA has the most knowledge on this subject .
jje

EFS folder exist, but is empty. You mean that flashing dont create EFS folder? or that not every pda?

Flashing does not create EFS folder that's why rule one is backup EFS folder .
neither does CWM recovery backup EFS .
jje

great...
I flashed back to original latest boot/pda/modem/csc and...
*#1234#: modem: unknown...
in About Phone: Baseband: Unknown

Ah I see... well seems like there's one Samsung employee that needs to be asking the hard questions of his bosses.. haha could you imagine "boss my phone is fux0red for no good reason... fix it or I go public with what I know" hahahaha
That's a little disconcerting to know its bugged out without any flashing.. anyway back to the problem.. couldn't be as simple as getting the IMEI off the box or an invoice or even from your cellular provider from their records and just use whatever to restore it. It cannot be an illegal act to restore it the crime would be in changing it and therefore committing fraud over wire/telephony or whatever its called.. from my understanding its not the changing the number itself thats the criminal act but registering the fake IMEI on the network and using data or calling or texting is when you actually commit the chargeable offence. Same IMEI as original means no fraud or misrepresentation has taken place so no offence committed. You need that tech guru booth that sells cases but secretly the salesman has the mad skilz. They could do it no doubt at all. Hmm I remember a thread in the sgs2 boards about rebuilding the efs but from memory it was phone specific due to the address and the manual way you write the info.. sorry buddy outside my skillset so in terms of actually helping you get the right address to write to and what to write I'm no good to you. You need to find a guru in the sgs2/3 or similar that willing to help with this.

there is a thread on the S2 forums on recovering from an EFS fubar.

Strange efs/imei problem, wont flash to stock

so I have a SR I just put a new (used, off ebay but new to me) motherboard in, and it works fine except for no imei/baseband, so obviously no data/voice/etc.
the efs folder seems to be fine...imei folder is in there, keystr file is there...I don't understand what the problem is.
the worst part is, only certain roms will flash...I cannot flash to stock, I've tried with odin and from recovery, a couple different stock versions of GB, ICS, and still no luck. It actually flashes, then does the "android is upgrading" screen, but then bootloops on the optimizing apps part. I've tried to flash to stock probably 20 times now, wiped everything, fixed permissions, etc...without fail it bootloops every time.
the only roms Ive gotten to flash are slim and jedi...no stock rom will flash, nor avatar and a couple others I've tried. but slim and jedi flash and boot right up...just have blank imei/baseband.
I've scoured threads for days trying to figure out what to do here...nobody seems to have my exact problem, and everything I've found about restoring efs/imei/baseband has involved flashing to stock...which I can't do.
anyone have any ideas?

Have you tried flashing different radios (baseband)?

That fix thread was one of the first I found, but as I still have my keystr file in the efs folder, I didn't think it would apply to me...I suppose I could make an external backup of my efs, delete it and try one of those methods from scratch.

read through the restore to stock sticky http://forum.xda-developers.com/showthread.php?t=1652398 and go through the trouble shooting sections, if that doesn't help u could have bad hw

so I have a SR I just put a new (used, off ebay but new to me) motherboard in, and it works fine except for no imei/baseband, so obviously no data/voice/etc.
the efs folder seems to be fine...imei folder is in there, keystr file is there...I don't understand what the problem is.
the worst part is, only certain roms will flash...I cannot flash to stock, I've tried with odin and from recovery, a couple different stock versions of GB, ICS, and still no luck. It actually flashes, then does the "android is upgrading" screen, but then bootloops on the optimizing apps part. I've tried to flash to stock probably 20 times now, wiped everything, fixed permissions, etc...without fail it bootloops every time.
the only roms Ive gotten to flash are slim and jedi...no stock rom will flash, nor avatar and a couple others I've tried. but slim and jedi flash and boot right up...just have blank imei/baseband.
I've scoured threads for days trying to figure out what to do here...nobody seems to have my exact problem, and everything I've found about restoring efs/imei/baseband has involved flashing to stock...which I can't do.
anyone have any ideas?

Hey, Im facing the exact same problem! just that my imei turned to 0 and basband to unknown after i upgraded to cynogenmod 10.1-rc.2.
It was working fine till suddenly one day i lost network. I tried everything like you did. So far ive had no luck fixing my efs!
What you can do is download QTPS and in it there is a RF NV Item manager to rewrite your efs. For that you need to put you phone into DIAG mode unfortuantely i cant get to that on 10.1nightly cynogenmod that im using.
I m stuck. I know for sure flashing roms or radios wont help at all. the same boot loop problem happens when I flash using odin, it use to work perfectly fine earlier.
Some how the nv_data.bin and such files are missing from my efs>imei folder that contain the imei data.
If you find something please lemme know too [email protected]

will do.
also, you may know this already, but just in case, be aware the skyrocket doesn't use nv_data.bin...I thought it did too when I first started searching around about this, and when i couldnt find it I was pretty freaked out...but then i found out the skyrocket actually uses 3 encrypted partitions rather than a nv_data file. so if you have at least some files in your efs/imei folder you may be in a better spot than it seems. of course if its totally empty, you'll likely have a lot more work to do.
I'll update if I have any luck.

Yes I have two files in my imei folder i,e keystr and mps_code.dat!
I tired changing them from root explorer! pasted someones else's efs folder! but still I cant fix my imei is stays 0.
i donno how to get to diag mode with this rom, otherwise i could have tried my luck with QPTS.

Incase you have broken your imei without backing it up, there is another way. And yes it is legal.
Here's the tutorial http://goo.gl/wtW29 and here's the needed tools (software & hardware) http://goo.gl/54mtk.

I actually have octopus box as well as the z3x samsung tool installed, however, they're both server activation based...the software is useless without an $89 (octopus) to $120( (z3x) activation.
I'd rather not spend that kind of money for something I'll likely only need once, so I'm gonna do as much as I can in the way of free solutions, and if I have no luck there I'll probably just send it to mobiletechvideos for their $40 efs/imei repair. I'm guessing they use one or more of these repair box programs themselves anyway, and will do the same job for only $40.
thanks for the suggestion anyway though..

There's this polish guy who probably also has all the same boxes and he takes €10 for imei repair by remote desktop.
http://forum.samdroid.net/f70/repair-imei-s2-5729/
And finally you could try helping the op of this thread to add compatibility for skyrocket, this would be free.

Isn't there any way to fix my imei on my own ?
Mt efs folder also looks good now with all the files it should have but still the imei remains unaffected.
Also i'd like to know that the qualcom nv tool showed my esn as dead and mied as 000....000 does the dead thing mean it isnt repairable ?
I tried using QPTS but this is where I get stuck.. (img attatched)

Obviously there is since some random polack can do it for you on his PC, the problem is the lack of knowledge.
Those who know won't tell you how, because they want € for it :crying:

People want money for it because it's mostly used for making stolen phones work again.
That means real life risks like fines, jail etc.
Of course there are lots of examples when people experiment with this or that and delete their imei accidentally, or want to change the imei for some other reason. But these are more rare.

An update...
I managed to finally get flashed to stock...still null/null imei & baseband unknown. Efs folder is still there with files, keystr file is on...not sure what else I can do myself at this point so, I guess its time for the Polish dude or mobiletechvideos.

unfortunately not for me. I finally got the polish dude to try restoring the imei remotely...he used like 3 or 4 different programs, nothing worked.
so, i just got a broken SR with a cracked lcd off ebay for $50 and used the motherboard from it.

Ohkies.
Did you ask the polish guy about the reason why he was not able to fix your mobile. Coz, I'm just having similar problem like yours. I tried working with all the local samsung service centre guys, nothing worked. One guy said that my mobile IMEI is locked in some database, so it is not picking or detecting my SIM, hence locked. I know that my mobile is unlocked and is valid, I ignored his comments.
I assume you changed your MotherBoard of the mobile with the new cracked SR's, so that it could take new IMEI instilled in new board. Is it so?
Also, please suggest me about any alternatives on how to fix this problem.:crying:

SIM card not detected (anymore)

Hi,
some issues with my brand new Xiaomi Mi 4i.... I'm getting reaaaally tired of this.
My story with this phone went well for a day. Then I tried to install a french ROM and I guess I did something wrong cause my phone was hardbricked. I managed to recover from that (throught steps I couldn't really remember, I tried so many things) but when I put my SIM card on my phone, it's not detected anymore, despite working on another device (a Lumia 1320)
I read it might be an hardware issue (and not covered by warranty, which is a real shame), but some stuffs tells me otherwise :
- the card was working before the hardbrick;
- MiPCSuite is messed up: it worked perfectly before the hardbrick, but now it's considering my phone as a "mi device" (and not a Xiaomi Mi 4i), I can't backup anything because my phone "isn't up to date" (despite having installed MiUI7 to check if the issue came from MiUI6 for some reasons)... I know it's nothing really important, but it might indicate that it's software related... right ? :crying:
I took the hardbrick well because I know it was my fault, and my fault only. But now that I have this issue... I'm kinda pissed. And the fact is that I don't have any center near me, because I'm in France (explaining why I tried to install a french rom and why my english isn't the best), so if I have to send my Mi 4i back, it will cost me a lot AND I won't have my device for monthes...
If you have ANY information that could help me, I would gladly take it. Thanks !
Edit : "baseband" is marked as unknown. Guess it matters...

did you backup your EFS (EFS Backup) before flashing custom rom? if yes then try tro restore your efs with twrp (i assumed you used twrp)

My motto always has been, and I know it's a very stupid motto, "if you backup, things are going to mess up". I never backedup anything, assuming everything would go according to plan.
So no, sadly, I don't have any EFS backup (or any backup at all...). I used TWRP, but since my phone resurrected, I didn't have the guts to reinstall TWRP. If I don't have any backup, it would be useless, wouldn't it?
I'm gonna try when I'll can to redo a full factory reset + fastboot flash using MiFlash Tools. Read it worked for Xiaomi Mi4, but don't have much hope. I guess the issue relies on something else than just a ROM. ( but I might be wrong, once again I'm really not an expert and this is my first Android device ( and yeah, yeah, I was stupid ) ).

try FastBoot Flashing, open this link
http://en.miui.com/thread-112662-1-1.html
i hope it only software related, not hardware related
*btw can you do imei checkup with your phone?

By IMEI checkup, did you mean verify if my MiPhone is a legit one? If yes, yeah, I tried and it's an official one.
If not, in the "Details", neither IMEI or IMEI SV are known.

It says "Invalid IMEI"... I flashed as your link said, but didn't work...

Well. "All I have to do" is to fix the two corrupted IMEI files. I found which ones are appropriate : mmcblk0p20 et p21.
I guess they are corrupted, I don't really know... Dunno if there is anyway to fix this, maybe by modifying the files with notepad or something like that. Really, I don't know, but I'm kinda despaired.

This might help

Thanks. Gonna try this.
Quick question : could you upload somewhere your mmcblk0p20 and mmcblk0p21 files for me to compare with mine?
Two ways to get it : with mi4i toolkit (EFS backup, it will be stored on /sdcard/efs-backup) or by following the tutoriel by magdag :
http://en.miui.com/thread-59832-1-1.html

Hi, it's me again,
I contacted the saler of my Mi 4i to ask if he knows any way to repair it or why. I was very surprised to see that the website proposed me 1) A partial refund (40%) on the websites account 2) A total refund (but the item is shipped at my cost) or 3) The same phone, half price, without the need of being reshipped.
I'm very surprised that it's covered by warranty... any ideas about that? Any chance that once I've shipped my Mi4i back, they'll ask me to pay for the replacement?

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

If the SIM card tray is damaged (for example, a piece of plastic is chipped off or a metal plate is deformed), this can be the cause of the problem when the Xiaomi smartphone does not see the SIM card.
I had such a situation on my Mi 3. In the service center they could not find the cause of the problem, I found it myself.
I hope this information will help to somebody.
