Is it specific for each device? Or does it depend only on finding the correct partition/block to be extracted?
Could you point me to further readings about that?
Thanks.
It is at least device specific, for extracting the bootimage, check this http://forum.xda-developers.com/showthread.php?t=1951426

What if everything is an illusion, and nothing exists?
In that case, I definitely overpaid my carpet....!

Well, that link is to proceed AFTER you have boot.img at hand. I want to find a way to extract it from my phone (assuming default.prop can be changed in there).
Thanks.
When you make a back up with CWM, you have a copy of your bootimage in the clockworkmod map, not?
That's the thing ... I am trying to figure out how to get that backup in hand at first.
Currently, following the method in http://droidcore.blogspot.com.br/2012/12/how-to-edit-initrc-in-android.html
It seems to use the same scripts as cited in your link.
Will post results afterwards.
Don't make things more complicated as they are. If you just install CMW recovery (or TWRP for that matter) for your device, you have your full backup in minutes, including one of your bootimage, then use the script from my first post.
I managed to find boot.img, made the necessary changes, sent it back to device (used MPK Rom Studio and SP Flash Tool).
The problem is, the reason I want to change boot.img is to root my device. I thought that disabling ro.secure, I would be able to do so. But I couldn't.
I believe cmw recovery, or twrp, both need my phone to be rooted, no?

I used a CWM image to root my device. Booted up with that image, and flashed SU....after that you can use su, and apparantly, with the changes you made with your bootimage...you'll be like God on your phone

I have the same problem, I need the boot image of my device to root it using magisk manager, but I can't find it.
Help!!!!!
Hey simply extract the boot.img from the stock firmware if your device is not rooted......
I think this only possible when you have root..
It is also not possible with adb without root...so
If your device is rooted with magisk then untouched boot.img is placed in /data folder as stock.xxxx.gz format and simply extract it....
If your device is rooted with one click root apps then download kernel auditor app and select backup option and the boot.img will be available in android/data/ kernel auditor specific folder....
Hope this help
Edit:- If your device is Mediatek, using SP Flash Tool you can readback. If you have Snapdragon, then bkerler's edl tool can readback. (No need of root)

just google "Latest Software Version for OPPO OPPO AX7" and go to the Software Updates page on oppo-uk.custhelp.com. Download 2.4GB ozip file (like CPH1903EX_11_OTA_0210_all_oStq7F7jxqfF.ozip) and unpackit with 7zip program. You'll find boot.img inside .ozip file.
I do not have root, there is no recovery or rom for my phone, Can I extract the boot.img from my phone storage, to patch it with Magisk?

Download the latest version of the rom again and unzip it. Then you should have the boot.img. If not download any other kernel for jelly bean for your device and flash it
Afterwards flash the rom again

This was discussed many times and it doesn't work because we have no separate recovery partition on our phones, kernel and recovery is one partition so it's impossible

I'd suggest you flash it from the recovery. It's a more successful and preferred option.

You could install from MobileUncle Tool:
Extract from zip file: recovery.img
Put the img file on your media storage NOT ON YOUR SD CARD!
Open MobileUncle Tool
Go to Recovery Update;
You will find there recovery image
Patch.
Second way is:
If you have allready CWM installed
Copy zip file on your phone
Restart to recovery
Patch zip file.
Hope this will help you.

There is no boot.img file there. Recovery.img is the file you must extract and patch.

Hi,
I am sure you understand, how to use ADB Fastboot.
Download latest SuperSu update zip and have it on SDCARD.
Search and download @desperanto or @AndroPlus Advance stock kernel on pc. Extract .img file ...
Get in to fastboot mode, and flash.img using ADB.
These Advanced kernels have recovery built in.
In recovery flash SuperSU zip.
Done... rooted on UL bootloader.

You can use the boot.img file in the Stock Rom which contains the kernel itself.
And then flash it via fastboot - done.
You can also make a zip file containing that boot.img and flash via twrp if you don't want to use the fastboot method.
