[Q] How to extract boot.img from my device? - Android Q&A, Help & Troubleshooting

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?

Root for Asus Zenfone 3 Max

Hello,
I've been recently trying to root my Asus Zenfone 3 Max (ZC520TL) using SP Flash tool,
however, I haven't found the correct scatter file for my device. Does anyone know where
I could find a MT6737 scatter file? Thanks in advance!
Hi. From my experience, correct scatter files that work (not just any random scatter file) reside in a ROM/Firmware zip.
Doing a little searching, I found that you can download stock firmware for you device from Asus officially. They offer them in the support section.
Here is the link: https://www.asus.com/us/Phone/ZenFone-3-Max-ZC520TL/HelpDesk_Download/
Should you download the official firmware specific to your device and unzip the file, (in all probability) you will also find the correct scatter file which you are looking for (something like xxxxx_scatter_file.txt).
(also keeping in place a stock rom is never but never a bad idea )
However... You mentioned that you need the scatter file to root??? I have not any idea as to why you would need SP Flash tool for any other reason than flashing stock.
Unless you are flashing full custom rom which cannot be flashed through recovery perhaps?
Anyway... Good luck!!!
Thanks for the quick response!

I needed the Flash tool because I was trying to flash TWRP, and from there install superuser. I did as you said, but when I tried loading the scatter file
the program recognized it as invalid. A huge thanks for the help though!!!

Ok... No worries!! We will probably figure it out in the end.
By the way, I am not sure I understand exactly how you were going to use SP Flashtool to flash TWRP. From my experience it does not work that way. You need platform tools (adb and fastboot).
platform tools here ----> https://developer.android.com/studio/releases/platform-tools.html
It is with these that you will unlock bootlader, and after bootloader is unlocked, first flash supersu, install busybox and lastly flash twrp.
Please look at my how-to root and twrp section. It is not for your device, but it will give you a good idea of the process: https://forum.xda-developers.com/android/help/lenovo-tab-3-8-tb3-850f-unbrick-root-t3598727
Please also check your private messages. I am sending you some links you might find helpful.

Is it possible to make a .app into a flashable .zip?

Hi there
I bricked my Huawei Honor 7i (ATH-UL06) while trying to root it, I only have TWRP in it now, whatever combination of keys I use to turn it on, it always goes to TWRP. So I wanted to know if there a way to make the stock rom (from the official website) into a flashable zip file, to install it through TWRP. The stock one is a .app file "UPDATE.app".
Here's the link: http://download-c1.huawei.com/download/downloadCenter?downloadId=91392&siteCode=cl
I hope you guys can help me, I can't think of any other way to do it.
There's supposed to be a way using SP flashtool, but I'm not sure if it works, I don't remember where to get the scatter file for it, and besides, for that I think I've to put it in fastboot mode, but the keys for that take it into TWRP, so wouldn't work, I think(?).
Please, help :'c

yes, but its a complicated process,
but you can also extract the .app file and manually flash boot.img, system.img through twrp or through fastboot

Yes it possible to to make .zip file (for flashing via twrp ) from .app file Check out for Huawei multi tool
I successfully used it for honor 7 but don't know about honor 7i you should try on multi tool thread
It's ok. I was going to, but ended up using Huawei Update Extractor to get the stock boot.img. Then installed it through TWRP, and rebooted to bootloader to get into fastboot. With that I only needed to flash system.img and recovery.img to get it unbricked. Took me a lot of time, but I got the phone back. I'll be uploading a flashable backup of the stock rom soon, so others can get it faster.
Thanks anyway.

So i can help u with updater script for flashing all those in twrp

stock boot image

I was rooted using supersu. Because I wanted to pass safety net I decided to unroot, but the supersu uninstaller gave me an error. So I unrooted using a zip file, which worked. However did this not restore to original boot image, which is why I am still not passing safety net.
Does anybody know where I could find the stock boot image and can I flash it simply through twrp?
Thanks in advance!
Edit: Or does dirty flashing the stock firmware fix it, too?
I recently flashed an original Boot.img to install Magisk on my Note 4. You basically just have to open a downloaded firmware (of course the one you are using at the moment), open it with 7zip and extract the boot.img file. You can then flash that with ODIN.

Extract the AP file with 7-Zip. But you can't flash a .img file with odin. You'd have to convert it to a .tar.md5

TWRP does have an install image option under... Well, install.
Thank you*jd1639 and jhill110 for the input. I'm not the most experienced at all this yet and I usually find myself in the deep end of the pool. I've already managed to soft brick my phone last year and just end up extra cautious since then. I just didn't want to end up wiping TWRP off my phone with a stock boot image with no way to flash it back on at the moment. Sorry I couldn't quote you two, my account is new and I can't use external links or quotes until the tenth post.

Install Original ROM Huawei on Y6 2018 Brand TIM Italy.

How should I install an original Huawei rom , no brand, downloaded from their cloud?

I have the privileges of ROOT and I have unlocked the bootloader, I can not install the

Help!
since it is not possible to install the ROM version "update.APP", unzipping this with "HuaweiUpdateExtractor", which files should I flash with fastboot in bootloader mode?
Is this possible?
Yes, use the HuaweiUpdateExtractor and flash the system.img with fastboot.
Best regards
Yes, use the HuaweiUpdateExtractor and flash the system.img with fastboot.
Best regards
which files should I flash?
you need to download the full rom, go here: https://www.mobileheadlines.net/download-huawei-y6-2018-firmware-files-all-versions/
download the FullOTA-MF for your model and extract the zip, after that use huaweiupdateextractor on the update.app and extract SYSTEM.img
reboot into bootloader and flash the extracted SYSTEM.img to your phone using fastboot flash system SYSTEM.img
please make a tutorial thread. i want to use the original rom too.

Root available ?

Is there any way to root this phone? I would like to root just to edit the build.prop for the camera api in order to install the Gcam port ....
If you have an unlocked bootloader, the patched boot generated by Magisk Manager did work for me.

Do you mind to elaborate about the steps taken to get and patch boot image?
What I did is I grabbed the "boot_X-FLASH-ALL-8F02.sin" file, used UnSIN tool to convert it to "boot.img" and then Android Image Kitchen AIK to unpack and repack the image (this step is necessary on older Xperia phone, is that the case here?), then finally patch the repacked boot image using Magisk.
But when flashing the new patched boot image, I get a non functional touch screen and wifi. I was able to control the phone using ScrCpy tool to mirror the phones screen on my computer and control the phone from the window that appears on the computer. But since WIFI won't even turn on, I couldn't even verify that Magisk was working or not.
What is worse, is that if I tried to flash the original untouched Boot image SIN or the converted IMG, the phone still has non-working touch-screen and WIFI.
FlashTool by Androxyde and EMMA tools do NOT support this phone yet. I ended up using Newflasher tool to go back to stock (still unlocked bootloader) and everything works fine, but no root.
I have the US model I3223 btw.
Thank you kindly, awaiting your response.

older version can not patch boot.img, because when you click "install the zip",it will let you update the new verison.

After installing Magisk19.3 with TWRP, my phone stuck in bootloop and can not enter the recovery mode.
I tried to flash I4293_53.0.A.6.96_1318-2077_R1A.ftf (Factory ftf. downloaded from experifirm) with flashtool to solve this problem.
when I tried to create bundle, I found that I4293 did not show in the ID list.
I can't do anything about it.
Anybody can help me plz~~ I'm fresh in XDA and just try to root my phone first time :crying:
This phone cannot be rooted at this time due to the lack of the img.patch and no driever.

Are you still stuck? For all of the latest Sony phones try NewFlasher instead.

Flashtool doesn't support our phones. Magisk 19.1+ currently doesn't work with our phones. Hopefully 19.4 will fix that.
