Easy (but long) sgs2 to ext4 image unpack script for Windows+adb+Phone

The common way to unpack such images - is to convert img file to ext4 with sgs2toext4.jar utility, and then, using LinuxReader to open and save files.
The other way I suppose to you - to use android phone and adb. It takes a few minutes - so it`s quite long.
Theory step by step:
1. Convert system.img to ext4.img with the same sgs2toext4.jar
2. Push ext4.img to sdcard
3. Loop mount image to data/ext4 folder
4. Make tar archive of it
5. Pull back ext4.img.tar to PC
6 Unpack it as zip - and you have unpacked image on PC.
Conditions:
- ADB, Java on PC
- root and busybox in the phone
- important! loop mounting support in kernel (boot)
- sdcard with free space mounted as /sdcard/
How to:
drag system.img to system_unpaсk.bat
Bonus:
system_img_remake.bat - all th same, but it let You to make changes in data/ext4/system folder - change apk and so on - and get back to PC new ext4 image - and flash it via FlashTool for ex.

You sir are a Genius (гений) pure and simple :highfive:
PS: Can you please support your MoreApp.apk here on xda so you can be given credit for this too :good:

MoreApp.apk is not mine ))) - some time ago I`ve made some changes to it - but I do not really think it is needed - my device (and others) have a lot of free memory to install apps - 2,5gb and internal flash 27gb - can be resized to increase data partition - so moreapp or app2sd and so on - are not actual anymore

Root Huawei Mediapad M5 10.8" LTE with Magisk

Preliminaries
open bootloader
a little bit understand what you doing
flash nothing if you NOT have FULL-Update from your build !
inside Update.app is all partitions you need
My device and build : Huawei Mediapad M5 - CMR-AL09 8.0.0.161(C432) 10.8" LTE
Huawei Bootloader-Unlock Site is closed, only way for BL-unlock-code is dc-unlocker (cost = 4€)
- M5 run
- Menu / System / over the Device : tap 7x on "build" (activate developer-options)
- Menu / System / developer-options : OEM-unblocking = aktiv, USB-Debugging = aktiv
- USB-Wire M5 to PC
- on PC / web-browser go to dc-unlocker, download Client, start Client and follow instructions
- you need dc-unlocker account, save username and password on PC (for use in future)
- i am use paypal to pay "credits" for dc-unlocker
- if finished now you have BL-unlock-code (save on PC for use in future)
boot in bootloader
- fastboot flash oem unlock "your BL-unlock-code"
TWRP
i am use https://forum.xda-developers.com/p10/development/recovery-twrp-3-2-1-0-emui-8-0-4-04-2018-t3773449
"twrp_p10_0.1 .img" : this work on my M5
IMPORTANT: /data decryption is only necessary if you have set up fingerprint and pin code.
boot in bootloader
- fastboot flash recovery_ramdisk twrp_p10_0.1 .img
if decryption work : TWRP need by start the PIN and then decrypt "data"
"Data successfully decrypted"
Root with Magisk
download https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Magisk.zip, copy to M5 (external_sd or intern/Download)
boot to recovery(TWRP)
- TWRP / Install Magisk.zip
- TWRP / Reboot "System"
if M5 run
start MagiskManager (if write update available then update)
check SafetyNet
check root with RootChecker or other root-app (example : TitaniumBackup)
NOW is M5 rooted
For your Security (and Self-Repair) is a good idea you have from your build "Full-Update"
https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146 [HFF]
search with HFF example : CMR-AL09 8.0.0.161(C432) = in HFF CMR-AL09C432B161
https://forum.xda-developers.com/showthread.php?t=2433454 [HUE]
unzip Update.app from Update.zip
with HUE extract from Update.app
- ramdisk.img
- recovery_ramdis.img
- system.img
HUE do automatic for all *.img *.img.header
- this 6 files copy to your adb-folder
Now you can Self-Repair with
- fastboot flash ramdisk ramdisk.img
- fastboot flash recovery_ramdisk recovery_ramdis.img
- fastboot flash system system.img
and your M5 is reset to stock-rom.
If you NOT use TWRP you can install Magisk with "patched_boot.img" with self-create
- copy "ramdisk.img" to your M5/Download
- download MagiskManager-v5.x.x.apk and copy to your M5/Download
- install MagiskManager
- if MagiskManager run inside "install", "download Magisk-v16.0.zip ?" = yes, "modify boot.img" = yes
select in M5/Download your "ramdisk.img", Magisk modify this and save in your Pad/MagiskManager/patched_boot.img
- copy patched_boot.img to your PC/"your adb-folder"
- in Windows open Command (DOS-Prompt-Window)
- go to your adb-folder (example: cd C:\ADB)
- if Pad run : adb devices (answer: your ID adb), adb reboot bootloader
- fastboot devices (check if Pad is online?)
- fastboot flash ramdisk patched_boot.img
if Pad rebootet check Magisk. if work : done!
i think this work for all Huawei-OREO-build's

Can you still get into fastboot? If yes, try hurupdater to go back to stock.

luckily, I was able to adb reboot bootloader from erecovery, however, I think dload should work (I won't test this though ....)
My fix was after simply reflashing the ROM once I was in the bootloader (I did not disconnect the tab while doing all this stuff ... )

Need help for rooting my Galaxy A7 2018 (SM-A750FN/DS)

Hi,
i want to root my samsung Galaxy A7 2018 (SM-A750FN/DS) in Android 10 but i tested and it dont work at all, i got a bootloop.
So i need help

To restore oneui (fix bootloop):
1. Download your device's firmware using samfw (or any other samsumg firwmare download site/tool)
2. unzip the downloaded file
3. Open Odin3
4. Click on the AP button and select a file named AP_sometext from the extracted zip folder
5. Do the same for BL, CP and CSC (for CSC use CSC_OMC_OJM_sometext and not HOME_CSC_OMC_OJM_sometext)
6. Click on flash, your phone should reboot automatically to samsung oneui
To root your device:
1. Install a custom recovery (try TWRP (works better for A750FN), if it doesnt work then try PBRP)
2. Download latest magisk apk to your PC from the Github Releases page (direct link)
3. boot into your custom recovery
4. go to advanced > ADB sideload
5. open terminal and run
Code:
adb sideload magisk.apk
(replace magisk.apk with the path to the downloaded magisk apk)
6. delete cache and reboot system
7. Enjoy!

i just install twrp but i got the start twrp screen and next some black line appeared in the screen and next a black screen
Update : i just restore to one ui

If you still want to root your phone, try using PBRP. I also had black lines but I dont with PBRP.

okay but how to flash PBRP ? there is no .tar file

Use this
NOTE: this is untested, if this doesnt work try to unzip the zip file from the post, and use heimdall to flash TWRP\recovery.img

PBRP work but whan i start sideload in PBRP Its write :
Code:
Starting ADB sideload feature...
But nothing next
Edit : Nvm

Now i have Integrity check failure when i reboot and it said to reset it but it dont disappears

Did you get an error while flashing magisk?
You can also use magisk without a custom recovery, see magisk's installation page

I cant install twrp, i get a lot of horizontal black lines on the twrp logo, and a lot of bootloops.
because i cant install twrp, and the only thing that i can access is the download "page", i cant try pbrp ither.

There are 2 fixes i know for black lines:
1. You can flash PBRP using heimdall/odin:
- Using heimdall (works for Linux, Mac and Windows, but from my experience it doesnt work well with Windows):
- - 1. Unzip the PBRP installer
- - 2. Open terminal/cmd in the TWRP folder (inside the extracted PBRP zip)
- - 3. Run
Code:
heimdall flash --RECOVERY recovery.img
to flash PBRP
- - 4. Enjoy!
- Using Odin3 (only for Windows):
- - 1. Unzip the PBRP installer
- - 2. Open the TWRP folder (inside the extracted PBRP zip)
- - 3. I don't use Windows, so i don't know for sure. Try to search online on how to convert .img files to odin format, then convert recovery.img to odin format and flash it.
2. Reverting to older firmware:
NOTE: this will revert security patches, therefore it is NOT RECOMMENDED. Do it only if method 1 didnt work and if you don't care about security patches.
NOTE: this will wipe your data. Make sure to have a backup.
- 1. Find your CSC code (search online for a CSC code list)
- 2. Go to https://samfw.com/firmware/SM-A750FN
- 3. Search your CSC code and click on it
- 4. You should see a list of firmware versions.
- 5. There should be a Bit/SW REV. Security Patch Lvl. section.
- 6. There should be around four versions that have the number 5 on the Bit/SW REV. Security Patch Lvl. section.
- 7. Download the OLDEST (most lower) one of those versions.
- 8. Unzip the downloaded zip file
- 9. Flash the extracted files using Odin3 (AP_sometext.tar.md5 to the AP slot, BL_sometext.tar.md5 to the BL slot and so on.)
- 10. Flash TWRP or PBRP
- 11. Enjoy!
You can also use magisk without a custom recovery, see magisk's installation page

I have carried out this procedure and tried to flash tar versions of TWRP and PBRP using Odin3, but both fail.
Software is Android 10 with patch level 1 November 2020, was previously the latest patch level.
Does anyone know what is causing the custom recovery flash to fail?

[Guide] Install Android 10 firmware on Nokia 7.2 (DDV) using Stock recovery

Hello everyone!
There are some handy tools to flash stock firmware on Nokia devices. In this guide, we'll explain how to install stock firmware without the need of any flashing tools.
Here's the download links for Android 10 Firmware (build v2_410_SP02) & boot image.
Download:
Android 10 - Nov 2020 - 00WW_2_410_SP02
Boot img
NOTE:
This is an OTA package which contains payload.bin file. You can sideload the package through stock recovery by following method
or
You can extract the payload.bin file using payload dumper and flash using Nokia Tool or pack the extracted contents as a zip file, then flash using Nokia Flash Tool (NFT)
___________________
How to install?
[This method is useful if you are from any other ROM / have erased all the data from your device using TWRP; Now want to flash the stock rom, but not ready to flash using above mentioned tools as they take more time for payload.bin extraction, repacking etc.,]
Let's get started!
- Keep the boot img on your PC
- Move the downloaded OTA file to the external SD Card
- Power off the phone
- Hold Volume down + Power button (device will boot into bootloader mode)
- Connect the device to PC with USB cable
- Open command prompt on your PC
- Flash the boot img using fastboot command
fastboot flash boot boot.img
- Reboot to Recovery mode (Select "Recovery mode" from bootloader. Android logo will appear. Press Volume up + Power button at the same time. Now the device will boot into Recovery mode)
- Select "Apply update from SD card"
- Navigate to the downloaded OTA zip from external SD card and select it
- After installation compete, you can reboot the device into stock Android 10.
That's all!
(In some cases, the recovery may ask to perform a factory data reset. Proceed to reset and then reboot the device)
Thanks: @Raghu varma @singhnsk @hikari_calyx @sayaoks

hello! thank you for the tutorial
this seems like the only method to downgrade to be able to unlock the bootloader.. unfortunately the boot.img link is dead, do you have it somewhere? would you mind reuploading?

this is ddva any ddv?

Is this the way how to get back to "normal" Nokia images?
The one linked in the first post can also be replaced with newer ota images? Like
