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?

take it to service

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][GT-I9305] EFS, IMEI Repair

Okay everybody,
I decided to write a new thread for my problem because I think my prob is a very special thing.
I'm from germany, so please don't wonder about my english. I think it is a understandable.
The story begins with a software update for my GT-I9305. After the update, the IMEI was just "null", after some work with google I found out that the efs partition was broken. With my bad knowledge for this case, I destroyed the whole EFS folder. I installed perseus kernel. And, there it was! The whole and correct IMEI. The solution was the perseus kernel (stock doesn't work, neither reflash). But then, after a while the phone doesn't boot anymore. I flashed Android 4.4.4 and my phone was revived but the IMEI was again "null". I have no backup or anything else!
So I spent approximately 20 hours or more to understand the efs thing. I found much solutions but nothing worked for me. So, here I am.
What I've tried before
-reflash KitKat
-reflash Perseus (not compatible anymore)
-formatting efs partition for a blank and new EFS for editing
-tried to edit nv_data.bin with HEX
-tried to backup efs with a 3rd party app and edit this with hex (the app doesn't support my GT-I9305)
and then, there it was:
-tried to use a working EFS partition from another GT-I9305
-editing with Qualcomm NV Tools! (I think THIS is the solution!)
I tried NV-items_reader_writer (1.0) and EFS Professional (2.1.73), but in both can't find my phone:
What I've done in NV-items_reader_writer
-dialed *#7284#
-at "Qualcomm USB Settings": "RNDIS + DM + MODEM"
-enabled USB Debugging in phone
-connected the phone
-opened NV-items_reader_writer
-checked the both boxes near the SPC box
-selected the right port (last: COM4)
-clicked on "connect"
-clicked on "read"
-> here it search the phone, but it can't find it and says "Failed.. Phone does not answer"
What I've done in EFS Professional
-dialed *#7284#
-at "Qualcomm USB Settings": "RNDIS + DM + MODEM"
-enabled USB Debugging in phone
-connected the phone
-opened EFS Pro
-clicked on "Qualcomm NV Tools"
-refreshed the Available COM Ports
-selected "SAMSUNG Mobile USB Serial Port" (last COM4)
-clicked on "Connect"
-> Here it takes few seconds and he stops and says: "Phone connection has been lost!" and "Unable to send SPC to the Phone!"
What I've tried to solve this problem
-tried QUALCOMM USB Settings: "DM + MODEM + ADB"
-reinstall all Samsung drivers
-tried to install Samsung Modem with Qualcomm drivers (failed due to wrong platform; I've Win7 X64)
-reinstall Samsung Kies (for actual drivers)
-tried to dial *#9090# (in my case, this menu is totaly blank)
-tried in factory mode
It could be that I forgot some....
Now, my question to you all is, do you know what I've done wrong? I mean, this is working for the most users, but why not for me? What do you think? Did you think I really forgot something?
Some informations:
Phone: GT-I9305
Android: 4.4.4 KitKat
Kernel: Stock (3.0.31-2760029 ; [email protected] #1 ; Fri Sep 12 13:08:24 KST 2014)
Buildnumber: KTU84P.I9305XXUFNI3
Windows: Windows 7 X64
Do you need more informations? Post it!
Please help me, I want to bring this phone back to life!
And yes I know, to change the IMEI to a number which is not your own is ILLEGAL and to prevent this, it is not well seen to talk about, but this is MY PHONE and I want to change the "null" IMEI and IMSI to MY ORIGINAL IMEI. If this is a problem, I can send a PM to an mod with my phone (where you can see the IMEI), my username on a sheet of paper and the original box with the IMEI printed on. All on one picture!
Simply... I need a hero! Be MY HERO!

im in the exact same problem as you. the reason nv tools and efs reader is not seeing your phone is because you have NULL well usb wont work. so try installing the original 4.1.1 firmware, then install perseus, then nv tools and efs software will see your phone. if you end up fixing it please help me out. upgrading to a later firmware is where I get stuck. just stays on the boot logo. and like you said perseus isn't compatible. you seem to know how to use nv tools so hopefully you can get somewhere. as I don't no how to use it. GOOD LUCK.

take your phone to the samsung if you have warranty.otherwise give to a phone repair shop for repair because your problem can only be solved with special boxes and equipments etc, and they have it. it will not cost too much.

I tried this, already. But I can't downgrade from 4.4.4. I don't read very much about this. I just know that this is a new security option from samsung (or Android)... I will tell you when I know more

The warranty is already expired...
This will be the last step I will do. Before this, I will try my very best to do this at home... But thank you for this tip
Edit:
What do you all think about this idea:
-I try to find somebody with a working EFS on GT-I9305 Android 4.4.4
-I get a backup from him
-I restore this backup to my phone
-I edit the duplicated IMEI with NV Tool to my IMEI
This requires that the NV Tool will with work with an existing IMEI and the the phone will be THE WHOLE TIME IN PLANE MODE to prevent IMEI ban...
What do you think? Will this work? Do I need somebody from germany (DBT) or is this not needed?

Take it to a phone repair shop they might have a way to fix it. And if they don't they might know someone who can and it would likely be cheaper than Samsung service center

Now I tried my idea with the EFS partition from somebody with a working GT-I9305. In my case, this isn't working... I think I must try the next step and try to repair it from a shop or so...

Hello,
someone could give me an EFS file because I deleted mine but my camera would not boot and remains on bootloop
thank you in advance

Repair shops aren't as expensive as you think to get my camera replaced all up cost 50$ au dollars and when I first got into Android I trashed heaps of phone's (low end thankfully) before I knew what the hell I was doing and never cost me more than 80$

But now I can enter *#9090# menu. But I can still not connect the phone with any DM Prog

If you were to 4.4.4 Official Stock rom can`t do downgrade the bootloader.What you have done is downgrade to Firmware with extracted knox bootloader.But you still with EFS corrupt partition.

Hm okay. I applied a "old bootloader" before here from xda. I don't know what it was exactly. There was a boot.so or so in it.
I will try my best. I mean, if I can beat this, this is a really great success for me. My next step is to restore a full NAND backup from a friends of mine (from a GT-I9305).
I wondered about that, after I restored a working EFS, there were no NV data.

Hi guys, i had the same issue: after a botched restore of nandroid backup (something to do with it being over 2GB, different story though), I lost IMEI (null/null) and no baseband.
I was running CM so I tried to flash the original Samsung ROM, to no avail. Then a whole bunch of other stuff that didn't work, until:
- I flashed kitkat (which failed due to some error in the install script, dunno why)
- then flashed my last nandroid, which I had already flashed with no restoration of phone functionality, HOWEVER,
- I then flashed over that nandroid the modem files (see here: dropbox.com/sh/d2ljv1ylvr9nvib/M7UzMgux4f) , mine was Modem-I9305-XXUENE2.zip for i9305 LTE Intl.
- tadaa! fixed
hope this helkps anyone, took me some 20 hours of tinkering

"Trying to flash" , what exactly did you flash ?
How do you flash it ?
Why dont you flash TWRP followed by ROM of any choice ?
NV normally contained in EFS partition, which can be backed up and flash from TWRP and QPST.
But again, your description is far from clear for us to help you.

When you flash using TWRP, did you actually managed to boot into system ? Or it stuck in recovery ?
Where did the nv corrupted notification appear when u were using TWRP ?
Prior to facing this issue, what you actually did ? I mean, did this phone work before ? Before you start getting this error, what you did, what you install, what you flash, what you delete ? Or did it just suddenly happen with nothing modified ?

You gonna need to ask someone to backup their QCN, take out the imei info, give it to you, and flash it using QPST.

This is absolutely not a issue, that requires using Qpst
You simply need to wipe data and follow the on screen prompts. (You will lose all data on your phone.) However the phone will work again.

Sorry that you are having these issues, But my comment was based on the photo that was posted on the OP. Typically formatting is the resolution. If you no longer have that screen available, you should contact an authorised repair center to fix it for you.
Otherwise If the phone is bound to your account, you could try what is listed here: https://www.mobilerdx.com/2019/02/xiaomi-mi-8-test-point-boot-xiaomi-mi-8-into-edl-9008-mode.html
Scams or Actual Fixes?
I have recently read about supposed hacks that according to a couple of Chinese BBS sites, has worked for some that require buying a specialised Jtag programming tool which cost about $60, that you use along with altered versions of following files: prog_emmc_firehose_8909.mbn.elf, mi8 persist image, rawprogram0, frp and a patch file. All of which that can all be obtained from here: https://romprovider.com/2019/09/mi-account-remove-xiaomi/ ( UMT Download)
Supposedly Chimera is another option: https://chimeratool.com/en/docs Again I have not used any of these tools with the mi8, I am merely sharing what I read about recently.
By the time you have spent the money acquiring the tools, it seems that you are better off just mailing the phone off to be repaired by an official repair center. Here is a web page that provides a list of official repair centers : https://www.pinoytechnoguide.com/2014/06/xiaomi-service-centers.html
Good Luck and try anything mentioned above at your own risk.
Edit: Have you tried the Flashall.bat method?
That should work since you are seeing the com port.

Hello, thank you for your answer, the mother is not linked to my account I disconnected to do the experiments. in my country i don't have a xiaomi assistance center, i get the error missmatching image and device.
There is no other way to unbrick without buying these tools so expensive that you mentioned

root cause of your issue is that you play with wrong qcn and messed up the nv,

You need backup EFS and Modem via TWRP first(better with OrangeFox). After you need Magisk first and some manipulation with QCN file via QPST. I will write it later

Question Help with an unbricked Poco M3 Pro

Hello guys, after some struggle trying to unbrick my poco m3 pro, i faced a new probem, my IMEI has gone, as a noob that i am, i didn't made any kind of backup, i'm trying alot of ways, and still i didn't had any luck to re-write my IMEI (i still jave the numbem on the box of the phone) to the device, i'm using linux, almost everything that i found is to windows, does jave any kind of tool for linux, or i'll have to put windows on my laptop just for this porpouse?
there is anychance to use mtkdrive tool, the same used to bypass security for sp tools to do this ?
thanks for now

if your mobile services works, write imei is not necessary. and it's a dangerous operation. so if your devices now works fine, my suggestion is DON'T TOUCH ANYTHING
all my old phones that after modding lost originals imei worked without problems
a mobile sim could work also with all imei numbers=0

sadly my mobile service don't work, i keep zero signal, and when i try to get IMEI numbers on Settings > About device, it says unknown on both IMEis

ok
first try your sim into another device to be sure is not damaged
second search xiaomi redmi note 10 5g fastboot engineering rom and flash. this rom should repair some high problems like your.
if boot and all work fine, update to miui13. good luck

its only information and you can use Maui Meta in Meta mode if you enter edl/testpoint, for me the first time lost two imei only return The Second imei, but send to waranty and change the Phone.
of coursed use a Semi Profesional Tools.

Did you find a fix? And where did you go wrong? Please let us know the mistakes you made so that we don't.

can i ask where did you get the eng rom?

Redmi Note 9 - How do I restore my IMEI? I don't have a backup of my nvram/nvdata but I have the numbers.

How do I write IMEI along with baseband version back to my phone? I really don't want to risk bricking it again, that's enough stress for me in the past two days
I heard that I can only flash IMEI 2 back to it, and if I want flashing IMEI 1 as well I'd need to install a custom rom on the phone. So if that's a solution I'd love if someone could help me with it. MIUI 13 is slow and laggy af (which is the reason I bricked the phone in the first place, to install a better ROM).
But here's something, when I flash the phone's firmware through fastboot, issues start to rise (as per my experience with it so far), but through SP Flash Tool, it's alright. So I'd love to know if installing custom ROMs using the tool would be alright, if not then if recovery is required or if fastboot is fit for the job. If that's an issue I'd love if someone could give me advice when it comes to it.
Old post 1: (not my current situation)
"Long story short, I bricked the phone and after months, I've finally been able to repair it (downgraded from MIUI 13 to MIUI 11), but I lost my IMEI. I have the phone's two IMEI numbers, but I could not find any tool to help me write it to the phone. Either that, or I don't know whether the phone should be turned on or off, or if there's any special mode that's required for that matter.
Help would really be appreciated."
Old post 2:
"It happened after manually installing engineering ROM on it, now I can only doubt it's BROM mode that's working and nothing else, but I'm not sure. SP Flash Tool doesn't want to work with the phone since I want to flash the stock rom back. I really need help please."

The reason why my phone broke in the first place was due to flashing a misc.bin file after following a YouTube tutorial. It was part of a process to download twrp on the phone unofficially. Since then I started looking for ways to fix it until I finally found a post that had to do with fixing nvdata corruption (which was the error I had prior to fixing the phone) which helped.
So yeah, I don't think I can trust flashing ROMs on my phone as much as before, but I'll still try the engineering ROM thing.

So um...it bricked. This time worse than before. It doesn't turn on at all no matter how long I press the power button. It was after I manually flashed eng rom.

Yep, it doesn't show up as it's name or "Android", it shows up as MediaTek USB Port (COM3), that's why I doubted it to be in BROM mode.

Hold on, it worked now for some reason when I disconnected the battery, but it keeps connecting and disconnecting so that's an issue.
I'll try to reconnect the battery and see.

I always recommend a NV Backup before messing up with your own device, that's all I know.
Download the file attached here but remember you can fix only second IMEI using this method. Please don't try to fix both IMEI or NV Data will be corrupted again.

The guy in the video is using MIUI 12, I have MIUI 13. I don't know if that's an issue but someone in the comments said something about MIUI or so. I'm not a professional but many times when I see tutorials they're very specific with the MIUI version.
Also, I'm not sure how to back up nv data, do I use mtkclient or is it somewhere in the attachment you sent me?
And one more thing, my phone's baseband version is unknown, could that affect the process?

You don't need the backup anymore and you can follow the tutorial in the video irrespective of the MIUI version you have.
I have also attached the files that are used in the video.

The phone keeps rebooting when connecting it to Maui META. Like it shows META MODE at the bottom of the screen but then it turns off. Now it's bootlooping. I guess I'll have to flash MIUI on it again. At least I still have access to fastboot and recovery.
Update: NV Data corrupted after flashing MIUI, but I got a solution that hopefully works.
Update 2: After flashing MIUI 11 (along with some other nvdata and nvram files, i think they're just empty), it works now and the error is gone. But as I said IMEI issue's still there. Maybe I would need engineering ROM for this one? Although it bricked my phone before.
Also, the phone started bootlooping before attempting the Maui META thing, so maybe it's either the manual formatting of partitions or the files I flashed on it.

Btw one more thing, I can update my phone right? Like, it won't break my phone? I'm good with MIUI 11 but I wonder if updating it would fix baseband version.
