How to repair IMEI ?

Hi Guys,
Here is my case.
Phone: Samsung Galaxy 3 LTE I9305 – Optus Branded.
I have done the following mistakes:
1- I flashed I9300 ROM not I9305.
2- Then I tried selecting NAND Erase all from Odin3.
3- Then I tried to re-flash the rom by selecting PHONE not PDA.
The total damage is:
Phone: Unknown
RF CAL Date: Unknown
BaseBand version: Unknown
So I think I lost the IMEI , I have no backup for it. So I have no network connection anymore.
I was able to:
1- To restore the stock rom.
2- Install Triangle away and clear the counter and the status back official.
I tried the following solutions to recover the IMEI, but it didn’t work out:
1- To flash the Param_Bin_I9305.tar.
2- I tried to use EFS Pro to recover and repair the IMEI.
3- I tried NV-items_reader_writer and QPST but:
a- The COM status NO Phone in both apps.
b- I was not able to see the option “RMNET + DM + MODEM ” under Qualcomm USB Settings. I can see RNDIS + DM + MODEM and others and they didn’t help.
I think I tried all solutions provided in the forum , I would appreciate your advice on this.
Cheers,

Nand erase was a bad idea as this would have erased all your efs area also including your mac addresses for bluetooth and wifi. So the problem runs alot deeper and is far more serious.
Best thing to do is warranty replacement. Had you have not selected nand erase I could have recovered your device for you.

Hi lyriquidperfection,
Thank you for your response.
1- Actually I'm able to connect to WIFI and Bluetooth, So do you think the erase was not successful? Do you see any luck?
2- I took Kies backup for all items just before I did the mistakes, does it help?
Thank You.

I removed the IMEI from one Mobile to remove the SIM lock I still can call and use the mobile like before
TWRP Recovery can Backup EFS what recovery do you use?
Maybe you can generate your own efs area the IMEI should print inside the mobile

Hi frogfire,
Thank you for the info!
Actually I tried to do that using QPST but:
a-The COM status is NO Phone when I connect the phone.
b- I was not able to see the option “RMNET + DM + MODEM ” under Qualcomm USB Settings. I can see RNDIS + DM + MODEM and other options which dont help.
Any idea?
Cheers,

Any help guys?

I took it to service and they wanna change the motherboard , is that the only option they have??

Ask them - they're the pros

Well you did wipe the NAND, nothing else you can do

Im not sure that NAND has been wiped successfully , because I can access the download option and the wifi is working.
Do you think it has been wiped and require a new motherboard?

You won't get more qualified help than from Samsung here. Exchange the board.

Thanks guys for the help anyway, I sent it to other service center, lets see how it goes.

So if they changed the main board, doesnt mean I will get new IMEI code for my phone?

Without a backup, not much.
The time to think about your IMEI number is BEFORE doing any flashing or modification to your device. Backing this up really should be the first thing anyone does before jumping into the fray.
Without a proper backup, you have an expensive media player.

going out on a whim here,, are we able to use someone elses backup to atleast get the stuff back then change the imei to our devices one?

[Q] i9305 Schematic/PCB photos for jtag

Hello,
I managed to give some hard times to me, after flashing an i9305 that I bought from eBay. The phone was rooted, in full working order, and when I flashed it to revert to stock, I managed to check EFS CLEAR, without taking any EFS backup beforehand. My odyssey is well knows to many of you; imei null/null, baseband null, to cut a long story short, I have a Samsung Galaxy S3 lte player. It does all but recognizing sim cards and provisioning networks (fair enough as I don't have a valid imei!!!).
I have gon ethrough the whole SGS2 forum, all topics, all solutions; I even unscrewed my phone to see if I can JTAG it, and that's only because QPST and EFS Pro cannot connect to my phone. Octopus and Samsung Tool CAN connect, but I cannot write imei. I cannot upload nvm files (I have a second, stock, and a friend of mine has one rooted from where we extracted the nvm in order to flash it on mine and rewrite imei), so as I read on the i9300 relevant thread, the phone can be jtaged in order to start receiving Rx and Tx commands and be able to upload the nvms and rewrite the imei.
The thing is that nobody tried to jtag this phone, and if someone did, nobody posted the resistance that has to be short circuit. As I saw here: http://forum.xda-developers.com/showpost.php?p=28073021&postcount=5 it is possible for i9300. Is there some schematic for i9305 then, or someone knows which resistance I have to short?
Any help will be appreciated...

you can still connect through Odin or adb, connecting is not the issue. there's nothing to write, imei is not stored in plain text, it's encrypted, so you won't be able to restore it if you don't have a backup. send it to service

I have the same problem bat I have imei back up sent it to repair center and after 2 month have it back
told me replace motherboard pay 250 euro bikose the binary counter 6.
You fixed Patrida?

Kalimera filaraki!
Unfortunately I was unable to fix it. Sotmax (member on both xda and myphone) offered to fix it. He could do it for a small cost but I would have to ship it from Thessaloniki to Kefalonia, and it was during the days that the ship workers were on strike. So it would delay a bit more, and I preferred to sell it. A guy over here (who then became friend and we exchange from time to time), bought it and fixed it in 10 minutes!!!!
He has schemas and JTAGs for most of the commercial phones, and I think that he had to open it and de/solder some pcb. It's not something difficult for him, but for you and me it's an issue!! The thing is that someone is now happy with the phone, and I am happy with my new gray 9305!
So if you need to fix it and you cannot find a workaround, you can always try talking to one of these 2 guys to have your work done! I know how much Sotmax is charging for the repair, and he says his job is guaranteed. you just have to be patient for 2 days to ship and 2 days to return (the fix takes no more than 30 minutes as he said). The other guy (his nickname is demernick at insomnia) didn't tell me how much he takes to fix, but it's much quicker as he only needs 1 day to ship from Florina to Thess, and another 1 day to return, so it's half time
There is also another one guy who writes in here. He says that he can do the job over the internet via teamviewer (you just have to follow his instructions and post the original IMEI from the box and phone under the battery), and he works with Octopus box ans Samsung Tool. If he manage to fix it, he charges you 10 euros via Paypal! He spent 2 days for me, so I donated that 10 euros to him for his work, even though he couldn't fix it... his website is cvxcvx.pl and I think his name in here has something to do with the website.
All 3 of them are trusted users. 2 of them are respected in here, and demernick is well established on insomnia!
If you need some extra help, feel free to contact me!

Are you sure you ticked EFS clear? Could it be that you had Perseus kernel prior to installing stock? I had some similar problem and as a result my phone only works with Perseus kernel installed.
I would try installing Perseus kernel to see if the phone magically springs back to life.

I was aware of Perseus, but that wasn't the issue. I DID tick the EFS Clear. After booting back to normal, the imei wasn null/null and the /efs folder was wiped out. it was en empty folder with just 1-2 files in it...

Thing is, the I9305 doesn't store IMEI in the EFS. Which is why I find this a little strange.

Yes, but the other strange thing is that instead of having a bunch of files, there were only 2 files in the /efs folder!

So get yourself a donor EFS and substitute the MAC addresses for your own data, it's on the box isn't it?

Phone does not connect to Network (started after being stuck at samsung logo)

Hi everyone,
I rooted my note and was using Jon ROM V3 for the last 3 months. Never had any malicious apps and my phone was working as usual.
Yesterday I took my phone and see that it is stuck at Samsung logo (an hour ago it was working fine). Tried reset and re-flashed ROM but no luck.
Later through download mode i flashed Official Indian Firmware(I live in India). Now I by passed the logo screen and the phone shows full signal bars but not able to connect to carrier network.
(tried all basic work out like removing battery/sim and re-inserting to phone and boot up)
I pressed power key and it did not show the power menu , it directly switched off mobile.
I rooted again with Philz kernel and flashed JON ROM. Still i see that my phone is not able to connect to any network. Also I observe that even here on this ROM when i press power key it directly turns off.
This is weird. I thought my IMEI was wiped off but im lucky to see that its still there.
I need your help. Im without my phone for the last 2 days now.
-
Jonathan

Note - I find that my IMEI number has been changed (to some generic IMEI 004999010640000) after i flashed the official firmware !!!! that's why it is not connecting to any network.
Someone please help me.

How did you flash the official firmware?
was it a tar file or a zip? I mean did you use odin?

It was a tar file The official Indian firmware I got from sammobile

either a glitch or you selected by accident clear efs.
anyways without efs backup hard to recover emei.
Do you get the simcard enter pinscreen on boot? If you dont then its not imei, if you do then you need someone like cvxcvx, search to fix it. That or Samsung

No I do not enter pin for simcard. I see my imei has been changed to 004999010640000. I tired fixing one problem and got onto another.
I guess there is no way other than sending my device to Samsung !
Anyways I appreciate your help. Thanks

You have a so called "developer IMEI". If you didn't safe your EFS then there is no real chance to restore it yourself.
There is a member (cxlcxl) who has hardware and can restore the original IMEI remotely.
But you still can use your device. Try to change the Sim Pin in the settings: you can use the same Pin for old and new (this is easier for me because sometimes I forget the new number).
After this the network connection should come back.
My workaround in my Pristine Custom Rom: one different jar-file that doesn't have the checks on startup from my old XXLSC dump. With this it works completely normal: Sim and Pin are always recognized from startup. I'm using this for many months now.

[Solved] NV IMEI RESTORE ISSUE - Samsung i9305 optus AUS

IF THIS HAS BEEN SOLVED SOMEWHERE PLEASE TELL ME ASAP
sorry this is first post. Cheers
Hello XDA!
man ive nervous to post..
BUT i have come a null/null IMEI reading after a CM10.1 bootloop issue and trying to flash a new CM.
I have been a XDA follower for about 9 months but I have never needed to post for anything, as you have carried all of the lords answers. :angel:
I have done, stock firmware reset, Param bin, wiped all done it again. etc etc.
Many a conclusion has led me to probably a service repair centre.
I believe one option will still work for my IMEI restore but my phone comes up with a command that makes no sense.
Any help would be appreciated.
I am currently using QPST Configuration to write my IMEI back to my phone.
I have got these programs http://forum.xda-developers.com/showthread.php?t=1804117
Aswell as another handy IMEI converter to make sure my IMEI HEX conversion correct. (sorry cannot link. cannot find)
I have been using QPST and can follow all steps, except my phone WILL not show on on active phones.
I have reinstalled drivers and followed all necessary steps.
I have tried it in recovery mode also in QPST and no active phone still.
I believe i can get this to work, just need it to recognize my phone, and ill write the IMEI and hopefully..
Voila.. i can call the GF and tell her to chill. :good:
IS RNDIS different to RNMET? (how big of an impact will this play on the process)

SM-G800F no network, changed IMEI

Hello XDAs,
After reading that Forum with much enthusiasm for a few...well...years, i got my first question.
I hope you can help me with a big problem on my g800f: I can´t register in network.
When I search for network it pops up a few results, but if choose one to register, it says "Can´t register. Try again later."
I did a few hours of research and found out it might have something to do with my IMEI (Note: till that day i did nothing to my phone, except cf-autoroot. But never faced any problems!).
So I checked my IMEI and it wasnt the original, it was changed to 350695200123951. So I googled a bit and realised it might have something to do with the efs-partition. Googled for solutions.
Found out it might help to flash a Stock-Rom, one with three parts, via odin so i did it. Everything worked fine, but my IMEI still was the different one.
I was a bit irritated so i searched for that IMEI. And there are a few threads (some in russian and arabian), also owners of a g800f, which also reported this problem: They did nothing, but sudddenly the IMEI changed to this number. One author tells he received a myserious call from the ukraine after this happened. He didnt answer it. I am quite sure i also received that call- I didnt answer it either.
So i googled even mre: "How to restore a damaged efs-partition, without backup?" I came to one very outdated guide which wanted me to delete the efs (after saving it on externalSD) and do a few mysetrious actions...
Well, i just realised i cant fully delete the efs, its not possible and i also cant apply my backup from external sd. Anyone knowing a solution for this?
But, the most important, how can i bring my g800f back into mobile network?
Or just: How can i get away from that cursed IMEI?
Any Ideas?
P.S. If you got any questions regarding technical details of my phone(CSC, AP, Kernel, Modems), just ask. I´ll answer.
P.P.S I´m excusing for that horrible english. I googled the entire night and i´m german.

I´ve just seen this problem being reported i a different thread. Guess the problem will be discussed there?

Hi All,
Did any one actually get a fix for this issue as I have exactly the same problem, my SM-G800F IMEI now also shows as - IMEI 350695200123951-01 which is for a blacklisted NOKIA 6310. If anyone can supply an absolute beginners guide for me as to how I can get my original Imei back that would be fantastic.
I am just a user of an android phone and have zilch experience of tinkering with them.
I have seen reference to things like Odin and flashing firmware and am quite happy to give it a go myself and learn
I will post this on a few other threads that list the same issue as I am desperate to get this fixed now as is a waste of a perfectly good phone !!
Cheers.

SM-G800F, can't register in network
Hello,
I have exactly the same problem. Since some month I got the message "can´t register in network". After checking all, I found that my SM-G800F IMEI has changed to a NOKIA 6300 IMEI.
If anyone knows a fix for this issue (set back to the orignal IMEI) , it would be great. All apps which I could find didn't work (XPOSED IMEI Changer Pro , Mobile Uncle Tools App, MTK Technikmodus... ), are not supporting S5mini.
I don't have a backup of the original system EFS file.
Would be great when one could help.
Regards
Chris

@S5miniChris somewhere in XDA I read that restoring the original stock (multiple part) firmware might or did help.
Gotta do it in Odin (recommended to use an older version like 3.09).

Thanks for your reply.
I have installed the original stock firmware. But it did not change the IMEI. Available for my model is only the single file " G800FXXU1CRG3_G800FDBT1CRE1_G800FXXU1CRG3_HOME.tar.md5"
Multible file firmware I couldn't find.
A manual modification of the IMEI should be possible with " Best smart Tolls " e.g. : BSTPRO 4.03 . But for the software a dongle is requiered. To purchase this is for one time use too expensive for me

Where from did you get the stock?
Samfirm_reborn tool already tried?
https://github.com/ivanmeler/SamFirm_Reborn/releases
Checking "binary nature" or "factory mode" downloads a multiple part rom.
Edit:
Checked tool and it's working.

I flashed now also with " binary nature " firmware downloaded with SamFim. The IMEI is still the same, it hasn't changed to the orginal IMEI.
I really can't believe that a firmware update will flash the E2PROM where the IMEI is stored. Therfor the orginal IMEI must be stocked some where
in the phone and by flashing transfered to the E2PROM.
