you have messed up your phone, there is no way you get modem back when you flash direct fastboot of latest rom., only hope is to be on flash a stock marshmallow base, and update to N using OTA updates, now you get deleted modem, but for imei you need more to write it in(google or xda search),...i hope you did TWRP backup of Efs.
try flashing this with twrp

How did you flash modem using fastboot....P2 unlocked bootloader don't allow you that....only system, boot, recovery can be flashed.
Thing is you didn't loose your modem in first place.

Fastboot modmst2

No simcard showing
But IMEI no still showing
How to fix that problem
I update OTA from 048 to s244

Update S048 till S244 using OTA only.
First Why did you erase....you shouldn't erase when you can't flash modem via fastboot....unlocked P2 dont allow flashing modem using fastboot command...only way for modem is update using OTA
Voice error is bcz of mismatch of OS and modem files....may be your modem is updated and OS is MM can be the reason for no voice. Instead of erasing OTA update till S244 could have fixed it......
Once you reach S244 via OTA, updated modem works good even you reflash S048 MM.

I tried already ota from s048 to s233
But doesn't work
Face same issue

As far as I know there is no work around for p2 modem errors and signal issues....

Why is this imie loss and modem issue occurs?

I believe I've lost mine. It's completely different to the one displayed on the SIM tray. I've tried going back to MM and updating to S244 but it didn't work. I'm stuck with someone elses.

Can you describe how you did it? My IMEI doesn't match the number on the SIM tray (bought a used phone and it's the only way I can identify the original number) so I suspect I'll have to erase the EFS and modem partitions before doing a blankflash rescue.

If you were to use someone else's EFS, wouldn't that result in you losing signal/not being able to register at your operator?

Use have flashable modem available for P2,
Or fastboot flash 6.0 stock ROM and do ota update till last update.
For imei, ask someone on stock to do tgis..
You can connect your phone to pc, install qfil or qpst, on phone dial ####8899# click ok to enter diag mode, in qfil it will read a com port, click tools then QCN backup restore.. click backup..
You will find a file in C:\temp:\00000.qcn
Keep it safe..
If you lose imei and network cuz of bad flashing repeat the process but restore and reboot..
If not on stock rom you'll need root and adb or terminal instead of dial code
su
setprop sys.usb.config diag,adb
and use hexa editor to find, and edit imei and restore it....done.

[SOLVED] SM-G930FD: DRK error + locked bootloader = bricked phone?

Hi all,
After screwing up my efs partition, I was finally able to make my phone boot with a stock ROM by installing TWRP and no-verity-opt-encrypt (none of the other options in this guide worked).
But it seems after re-installing the stock ROM the "OEM unlock" option was disabled somehow and after powering off my phone it didn't boot again because of TWRP. I reinstalled the stock ROM, but the DRK error is back.
So:
- I can't boot the stock ROM because I'm getting the DRK error.
- I can't install TWRP and no-verity-opt-encrypt because OEM unlock is disabled.
Any idea about what I can try to fix it? Or am I completely screwed up?
EDIT: I forgot to mention that I still can flash and boot Combination ROM, but there's no way to unlock the bootloader from there as far as I know.
EDIT 2: Solution

I don't fully understand your post, let's make something clear:
Flashing stockrom via Odin/KIES gives you the DRK Error after/while booting
You currently can not flash TWRP, as OEM Lock is on
You currently do not have TWRP because you flashed the stockrom
You do not have a Backup of your /efs partition
AFAIK things like the IMEI are stored in the EFS partition, and it really isn't a good idea to do anything with it unless you have a backup

Hi jaannnis, thanks for your reply.
Yes, everything you say is correct.
Regarding the third point, I had TWRP, but I replaced it with the stock bootloader after the phone stopped booting with TWRP due to OEM being locked.
I thought I had a backup of my EFS partition, but it turned out to be corrupted somehow. But even if I had a valid backup of the EFS partition, how can I restore it with a locked bootloader?
Anyway, the IMEI is not an issue. Actually, after my EFS partition became corrupt, I was still able to use restore the IMEI using Combination ROM and then boot the stock ROM using no-verity-opt-encrypt and use the phone to connect to the network with the correct IMEI.

Solved!
OK, I managed to solve it!
I solved the steps in this post in a Spanish forum.
These are the steps for those who don't speak Spanish:
Install Combination ROM and check the IMEI is correct by typing *#06# in IME as explained in the XDA post by CuBz90 mentioned before.
Untar BL and AP from stock ROM and tar them again containing only cm.bin and sboot.bin in BL and boot.img and system.img in AP. This somehow allowed to boot the stock ROM bypassing the DRK error but with some parts missing like Recovery or Google Apps.
That's anyway enough to be able to enable "OEM unlock".
After unlocking OEM, I was able to flash a full stock ROM and TWRP.
Apply no-verity-opt-encrypt from TWRP as explained in the XDA post mentioned before

is it easy for you to upload BL and AP which you created because I don't know how to create them as you write.

I think you should usually use a stock rom specific to your phone because of the modem drivers and all that stuff, but for this purpose any version may work since you don't actually need to make phone calls and it's only for unlocking the OEM.
If you use Windows, you can use 7-zip to untar the AP and BL files included in the stock rom and tar new ones with the files I mentioned.
I did this almost five months ago and I no longer have the AP and BL files I used, but I still have a copy of the stock rom for my phone (G930FXXS1DQHM_G930FOJV1DQEB_XSG).
I will try to pack the special AP and BL files again and upload them, but it can take ages with my upload speed. It won't probably finish before tomorrow.

Shared on telegram, thanks!

I'm not using qcn

1. Flashing 7.8.23
2. 7.8.23 root ( patched_boot.img flashin using fastboot mode )
3. Usb diag mode on (dialler open trying or adb using su diag mode open )
4. Dualwriteimei using and restart phone aaaand booom imei restore (dualwriteimei is youtube searching only small size program and very very best )
5.Phone fastboot mode on and 8.1.10 rom flashing and booom

New telegram link:
https://t.me/joinchat/G1MMfkc6EbEZL-62Ii5YmA

thats not permanen, at last for me, maybe work on 7.8.23, but after update via ota or fastboot, after reboot or reset factory on setting imei unknow again
my solution right now, using custom rom, with august security and push modem file from latest stock rom for update baseband

It works, but if you want to update whole system, you have to backup partitions modemst1, modemst2 or EFS in TWRP, after you backup that, flash the new oreo firmware without data, if dont starts, recover the EFS and try again, if dont, do factory reset and if you haven't IMEI yet, restore de EFS, the problem here is, if you restart your EFS would be corrupted, so you have to restore the EFS and force update to the lastest update with EFS already installed, if youre lucky your EFS never be corrupted again

In my case everything is working fine
No issue upon updating or restoring

than so much raj bro 100% working method

I followed this procedure some time ago and haven't had issues. However today I flashed a new Oreo image and suddenly my IMEI was 0 again.
I restored my EFS partition using TWRP and now everything is fine again, except that my smallband version is back to 953_GEN_PACK-1.... which I think is the version that shipped with tissot_images_7.8.23_7.1. I wonder if it's a problem to run with an older smallband version?

Someone there who can help me fixing my IMEI? I have pushed the "flash_factory.bat"-button...
Mi A1 is working and rooted, no 30sec boot loop anymore, but QPST recognize my mobile just for secondes.
I'm holding my IMEIs in hand but unable to get them into QCN sinced days.

i was Restored persist.img via twrp terminal but my phone still restaring continously

dd if=/dev/zero of=/dev/block/mmcblk0p14
dd if=/dev/zero of=/dev/block/mmcblk0p15

Im sooo stupid kiddo :crying::crying::crying:

Bro my telegram @Byramklc add me
Sent from my Mi A1 using XDA Labs

While I did finally manage to restore my IMEI, I found your "guide" really confusing.
You should without a doubt write it better, so people might understand it better as well.
I've been doing custom Android stuff for around 10 years. While I have never developed anything, I have gotten as far as to the point to where I have had to edit files and input hex.
You should _really_ mention when and how you use the files you provided.
You should also provide the "how-to" on editing the files.
I finally got it to work, but I had to read three different guides before I got it.
Still.. Thanks

Can someone confirm that PSN and FSN will missing if using flash_factory ?? (FSN&PSN can be found on *#*#6484#*#* Version Information)

hello guys ,thanks for the guide, i've restored my imei but the mobile data network still wont work, what it can be?
EDIT: I've resolved by using a newer version of qpst software, the 2.7.472.4 one

I managed to get IMEI back wifi and bluetooth working but sim network lost.
Sent the mobile to service center and they changed the motherboard.
Is this the only solution.......

were you able to restore sim network as well???????
If yes pls write a complete guide with all the tools and files used

Question Is there any issue backing up partitions from EDL, MSM resetting, unlocking bootloader, and flashing the backed up partitions?

Original title: Looking for backup of super partition for T-Mobile variant
If anyone is still on the latest stock T-Mobile ROM and can back up their super partition from TWRP and send it to me, that would be great.
My bootloader is locked btw.
A few days ago I tried running the DSU Loader that is enabled in Developer Options.
When I received the notification to reboot into the Generic System Image, my phone booted to a qualcomm error screen, and then after rebooting again, it showed a screen that said "Your phone is corrupt. It can't be trusted and will not boot."
From research, it seems to have messed up the system partition, and using Qualcomm Product Support and Oneplus Phone Reset tools I can backup and write to the phone partitions directly. If someone with a T-Mobile Oneplus 9 and has a unmodified super partition could be so kind as to upload a backup of their super partition, I would greatly appreciate it.
You can upload to mega.nz, they give you 20GB on sign-up.

Why not just MSM?

So I don't lose userdata

avid_droid said:
Doubt anyone will provide a super partition of "Their" current data. Reason being why I mentioned using MSM. No offense to you,but,caution should be taken before flashing anything knowing the dangers of flashing. Not sure if anyone will provide it,but, I would recommend MSM.
Doing a flash on anything is solely the users mistake/error and owns responsibility.
Trust me. I've flashed and bricked at my own discretion and advise everyone to do the same with any type of flash.

My bootloader is locked. It shouldn't be possible for my device to end up like this.
I did not personally flash anything, it was DSU Loader in Developer Options. Also I can not flash anything, my bootloader is locked.
Also the super partition only contains system.img, system_ext.img, vendor.img, odm.img, and product.img.
Any user data is stored in the userdata partition.

I'll see if I can extract and provide for you later. If worst comes to worst,just prepare to do a MSM restore

Oh I'm prepared for MSM restore, I've just been doing research to see if there is anyway around wiping userdata.
Thank you for your help.
I see you have a Oneplus 9 Pro, unless you happen to have a Oneplus 9 as well? I need the super partition for only Oneplus 9 non-pro Tmobile variant.
Part of the security are some of the properties found in build.prop in the super partition. For example, the build fingerprint needs to match exactly
com.android.system.build.fingerprint: "OnePlus/OnePlus9TMO/OnePlus9TMO:11/RKQ1.201105.002/2107151801:user/release-keys"
I assume on the pro it would have different build fingerprint?

I ended up in an EDL loop when trying to convert my second OP9. I think I took a full backup of the T-Mobile firmware before I set it up. When I check, I'll let you know if I have a super backup.

I think I've figured something out.
I can back up all the partitions from EDL mode using this EDL tool, and then I can MSM reset, unlock the bootloader, and then flash my backed up partitions through fastboot. Anyone know of any reasons why this wouldn't work?
The only issue I can think of is if there are encryption keys resident in some place other than the UFS storage and they get cleared by MSM reset.

Yup, looks like the keystore partition I backed up is all zeros, might just be an unused partition though

[CLOSED]Help me! Poco F3 GT (K40 Gaming ) imei repair failure ，and In the absence of a backup, cleared nvram and nvdata , now boot access miui!

As shown in the title！
I、Now I need two backup files urgently —— 'nvram','nvdata'.
II、My actions are as follows——
1.I use mi flash tool to Install the 'k40 gaming engineering rom ' after that I unlock BL.
2.In the Eng. rom, I use Modem Meta to repair imei ,Everything is going well， but when Modem Meta Display a line of words 'write imei 2 sucessfully' , Very strangely , reboot ,the imei is hasn't changed. Following other people's tutorials in engineering mode should could success, Why?
3.Then I use adb command—— fastboot erase NVERAM and fastboot erase NVDATA , terribly, I forget backup that.
Now，I can't reboot my phone, and I also don't have two files Nvram and Nvdata to restore ,help ! thanks!

No working.
in the official rom ，modem meta can write imei in meta mode (that’s illusion), but reboot, new imei is working.
In the engineering rom, Same as above. It seems eng. rom for poco f3 gt is different from other Old phone, because other phone can write imei in the eng. rom,
But fastboot can erase nvram, then imei is a string of zeros,now imei can be changed successful,only imei slot 1

So I think the official nvram and nvdata is protected ,Both official and Engineering rom，when I erase nvram and nvdata , I changed imei slot 1 successfully ,you can search YouTube ，There is only one video, he deleted nvram file,imei changed successfully

All in one, you can't make any changes to the original nvram and nvdata file, the file is protected, when you erase that, the system generates a new file that is cleared of zero, You can only modify the new file ，and the new file is unable to pass official rom boot detection

Thread closed since discussions about changing IMEI are not permitted as it is illegal.
