IMEI backup/restore tool for Samsung Galaxy S4 AT&T SGH-I337 & Bell SGH-I337M
Brought to you by AntaresOne​
NOTE: This is only for Galaxy S4 with Qualcomm Snapdragon 600, Galaxy S4 Active version is here, Exynos 5410 (GT-I9500) version is here.
To devs: modifications & redistribution are not allowed. Contact me before including my work or any part of it in your stuff.
Explanation
What is IMEI?
Wikipedia
Why should I backup it?
When you start to mod your phone, sometimes may happen that you lose it (a bad flash, a wrong mod...) and without your phone is like this. Shortly, you lose mobile network forever.
The Qualcomm variant of Galaxy S4 doesn't have IMEI stored in EFS as most people think, it's stored in another place. Partitions to backup/restore are 8, each is required by the system to have IMEI. These are: EFS (there is IMEI's country code), modemst1, modemst2, m9kefs1, m9kefs2, m9kefs3, backup and fsg. It doesn't do miracles, so if you lose IMEI and don't have a backup, you're lost.
Features
Complete IMEI backup
Autozipping of saved partitions
Installation
Download tool from the link below
Put the zip file in your sdcard
Reboot in recovery
Install zip from sdcard
Choose downloaded zip file
Reboot system
Usage
When installed, the "imeibkp" executable goes in /system/bin. Obviously root is a must. This is not an app, so to run it you must use Terminal Emulator. It's very user-friendly and n00b-approved (joking :laugh, normally you shouldn't run into issues while using it.
Open Terminal Emulator
Write su and press enter (this is to obtain root access)
Invoke this tool by writing imeibkp and pressing enter
To restore just invoke again imeibkp
In case you want to export your backup, it is in /sdcard/IMEIBackup and called IMEIBackup.zip (Internal Memory on PC through USB connection)
If you change ROM you'll lose this tool (you'll not lose a backup already made), in this case just follow again Installation steps

Excellent, it works fine this time. :good:

Tool is very much appreciated. Is there another way to install this(and other tools), other than rebooting to recovery?
Thanks.

I am guessing this won't work on i337m?

I just tried that(cat /proc/cmdline) and somewhere in the middle of all the info that came up, I saw samsung.hardware=SGH-I337M. When I run imeibkp I get:
unknown device! GT-I9295 , GT-I9505....SGH-I337 is required
Also tells me busybox not found(not sure if that is required)

Thank You so much DEVS for your time and efforts for all of us in the Android community!!

Thank You for your awesome work!! works flawlessly.:good:

I didn't realize the i337 and i337M were so different that this very useful tool can't work on the M version.

@AntaresOne
I'll attach the output of my commands here as a zip to make it easier for you. I have the i337M version.
AFAIK i337 is the bootloader locked AT&T version and i337m is the Canadian version with unlocked bootloader but no other differences.
Thx for making this tool and now fixing it for us Canadian galaxy s4 users !
Cheers
//edit
The zip name isn't the best lol there's no actual imei files included, only the output of the 2 commands your asked for

Update!
Now compatible with SGH-I337M
Download: https://www.androidfilehost.com/?fid=95916177934537090

Ya thanks i337m user here. I had to CD to the system/bin to get the command to run

Thanks for this amazing tool...

@AntaresOne

Sorry for late reply mate. G9650 using Snapdragon and as i know Snapdragon variants dont have unlocked bootloaders. Until you find a way to unlock it, you only got a refused boot. and hanging on splash screen. And no one want that sitution. Sorry again.

Ill have to check it out some one told me we cant do it any more. they upped the security and blocked it suposedly

Thanks man if u managed to mod the bootanimation file to make zip bootanimation instead of qmg that would be nice

The zip works well but for some reason the image isn't centered.

Thanks. Working well on Alexis v1.3 ROM

Any update on this? Will it work e.g. with newer system-as-root partition layouts in devices such as Galaxy Note 10, 20 ?
Thanks!

Lets gooo!!! Custom ROMs are finally here for Alioth! BTW, dumb question, but is there any difference between alioth & aliothin (Mi 11X)? Can I flash this on my device without issues? I don't think there are any differences but I just wanted to be sure before flashing this weekend when my 168 hour wait time gets over!

At the moment I have not succeeded or I do not know if the cts profile will pass, I am testing

As for testing earlier, CTS won't pass yet. Dev will look into it. Even with magisk props it still won't pass.

CTS check in Magisk is broken, CTS itself should be fine

nice, bro. you're the fastest man alive.....

How can I wipe xiaomi.eu and flash old firmware in order to come over to this ROM?

The only thing that keeps me away from buying this device is its camera performance on MIUI (As per the reviews). So, is it any better in this custom ROM?? Some samples with comparison will be very much appreciated.

Esta rom se puede instalar mediante TWRP en el POCO f3 estando en la XIAomi.eu 12.5? saludos y gracias

F3 isn't obviously a cameraphone.
But IMHO camera performance isn't that bad, especially when photos are taken in good light environments.
For now the stock camera app is the first and best choice, because it's device-optimized.
But I think that sooner or later we'll have a good XML for the Gcam.

Question Hard brick moto g30

Hello guys, I recently tried to Downgrade the Moto g30, but something went wrong, the screen was all black, the cell phone does not load, but it recognizes on the computer as Qualcomm HS-USB QDLoader 9008, I already downloaded the drivers from Motorola and Qualcomm, I downloaded BlankFlash and tried to make it go back to normal or when I do fastboot devices the cell phone does not recognize and perform the commands. I already downloaded the drivers but it still isn't going please I ask someone to help me.

My guess is that your phone isn't hard bricked but soft bricked:
When the phone has gone through problematic conditions such that it quits the detection of USB, charging and everything that you provide to it then the phone is unfortunately hard bricked.
A soft brick is something that occurs when you perform a dirty flashing, will say if you flash any ROM on your device without doing the factory reset. Or else if you flashed a ROM which was not made for your phone.

This is incredibly suspicious, my Moto G30 ceased to work yesterday as well. I found this discussion about Pixel 3 phones failing en masse, with similar symptoms. I'm still prodding the phone with whatever tools I can find, but I probably will try to get it back to the carrier to get it replaced.

Are you sure you flashed your channel Stock ROM?
I think that was it... Well, try to make Blank Flash with the file that I leave attached to this comment.
Instructions: Please press Volume Down and power on at the same time for 10 seconds, then connect to PC and run blank flash. Just in case it's the .bat file

most of programmer files with blank flash are locked and not allow system and boot.img flashing, try with qfil if works, otherwise jtag or try to find a similar lenovo phone (if exist) and use programmer from that

How To Guide [ROOT, Recovery, ROMs...] - S21 FE

Presentation:
Hey guys, well let's start with the wonderful world of android development for our Galaxy S21 FE device.
Tips and debloat(root not needed): [ADB] [NO-ROOT] Extreme Samsung Optimization Guide
Recovery:
TWRP:
Exynos: XDA Thread
Snapdragon: XDA Thread
Magisk(Root):
Installation:
Enable developer options by pressing several times on ¨build number¨ and then in developer options enable ¨OEM Unlock¨
Turn off the device
Connect your device to the PC while it is off via USB cable and quickly press and hold the volume up and down buttons until a blue screen appears (if it appears, congratulations you have entered samsung download mode)
Follow the steps that the download mode shows you to unlock the bootloader
Your device will then perform a format data
Restart in download mode
This time go to the flashing section
Download the necessary kernel (Boot img patched magisk) for your model
Rename the file to ¨boot.img¨
Compress the file in a .tar I mean in boot.img.tar so that odin can flash it
Load the file in AP in odin
Download and flash via Odin the vbmeta file also in AP
Flash and wait for the device to reboot, congratulations you have magisk on your device
Exynos:
Boot based on: G990EXXU1BUL5
Magisk version: 24.1
Download
Snapdragon:

Your model is not compatible with any kernel that I have published here?:
Download stock firmware of your model (I recommend you use Bifrost to do it: Download )
Extract the AP file from your downloaded firmware
Install the magisk app Download
Open Magisk app
Select the first ''install'' button
Uncheck the ''recovery mode'' box and tap on ''next''
Select method ''select and patch a file''
Find your firmware AP file and let magisk do its thing (Magisk will create a new AP and inside you will have the patched kernel img)
Flash the new AP file with Odin and the vbmeta as explained above
vbmeta file:
Download
Source:
Samsung Open Source
opensource.samsung.com
ROMs:

how to flash ldu samsung so that the network works

How to upload TWRP or root when the phone is branded? Neither method works. Despite the OEM unlocking, the screen for uploading the software is:
ERP LOCK: OFF
OEM LOCK: ON (U1)
KG STATUS: ACTOVE
VOID VARIANTS: 0x0
I've tried everything ... Hepl!
Usually odin throws a bug on vbmet. Attaching the vbmeta disabler file does not help.

Hi, I'm so happy to be able to root my s21 fe with your guide, I followed your twrp guide and this one. I also used the one ui optimization guide.

Eo you have any idea as to what might be the cause?
