How to do the instructions in "update-binary" of SuperSU manually ? - MTCB Android Head Units Q&A

Hi all,
I want to root Android 4.4.4, as you may know the only way to root it to use pre root image file.
So I used "RK3xxx Firmware Tools by SergioPoverony" to extract "System" and "Boot" files,
No I have to embedded the SuperSU manually " explained in "META-INF\com\google\android\update-binary" then reflect all the permissions for the file into "system_statfile.txt" then repack the images via the same app then flash the drive.
me experience here is limited , can any one tell me how to follow the instruction in the "update-binary" file to install the superSu to be able to root the update.img ?
Do I have to use Linux or Windows is good to go ?
Thank you all.

[Q] install custom recovery - libsub error:-12

Hello Community,
I tried to install custom recovery using this manual "wiki.cyanogenmod.org/w/Install_CM_for_serranoltexx" (<- cannot use the link function, because it's my first post). I followed every step. At point 9 I have to make commands using the cmd. Unfortunately the result is an Error:
Failed to access device. libusb error: -12
I had two insecurities while following the manual:
At point 4 I had to rename the recovery image but I'm not sure what the recovery image is. What I downloaded was a .tar.md5 file within a .zip. Do I have to rename the .zip or the .tar.md5? The renaming causes a change of the file type and I cannot really understand, why they didn't put the right file in that .zip at the beginnig...this step is a bit confusing
To point 5: I deinstalled Kies and the device driver in the Windows operating system. Since I've done this, there are appearing two devices in the zadig.exe when I connect my S4. I installed the zadig driver for both of them.
Im using Windows 7 x64
I hope someone can help me, for this moment I don't know what to do further...
greets

I don't know about the libUSB error, and I haven't modded a Galaxy S4 mini, but I have installed CM on Galaxy Player. The tar.md5 has to be extracted from the zip; it is in fact a tar.gz file (tar archive compressed with gzip), but you don't have to rename it.
I flashed the Galaxy Player with Odin 3 v. 3.04, after having installed Kies to have the drivers installed. The Player showed in Odin with something like "ID:0 COM"; I then clicked on the "PDA" button, then pointed to the tar.md5, and clicked flashed, and it worked.
Here are my 2 cents :^)
Is your phone rooted? If rooted already it easy! For the most noob method, install ROM Manager from https://play.google.com/store/apps/details?id=com.koushikdutta.rommanager and ROM manager will install the CWM for you. From there, its pretty simple.
If it not rooted, that the first thing you'll have to do.

I found out, the .tar.md5 is also a compressed file. If I extract it, I get a file called "recovery.img". At this point it's not very clear what to do. Because there is nothing to rename. And even if you are right, the tutorial would be also wrong.

This is for installing the custom recovery, that's is the root, isn't it? I had the problem that Heimdall doesn't gets access to the device (lubusb error: -12). It's probably a driver problem.
However, I solved the problem by doing another method using odin. The root was succesfull. Afterwards I will flash the custom rom.

No, custom recovery is not rooting. Not my favourite method but it easy enough, try this: http://www.kingoapp.com/
It a universal root for JB and it will prompt you to install CWM afterwards.
After installing the CWM I rooted the device. I succesfully installed Canogenmod 10.2.1. The Tutorial says explicit, that it only helps for 10.2.x but I want to install the Nightly version which is running at CM version 11. If I could, I would ask this questions in the threat but I'm not allowed yet to post in the developers section. "forum.xda-developers.com/showthread.php?t=2474054"
Can I use this tutorial for flashing CM version 11?

[Guide] Root Oppo F1s(A1601) + SuperSU without custom recovery or unlocked bootloader

EDIT: This root method has been outdated, see the newer guide instead https://forum.xda-developers.com/android/general/tutorial-root-oppo-f1s-flashtool-6-0-t3651220
Why I made this tutorial:
Recently some members claimed that KingRoot is not working for Oppo F1s(A1601) anymore, I assume it's because Kingroot uses cloud based root method, means Kingroot downloads root package and command from cloud and execute on your phone. Maybe the problem was caused by the change of their server, some configuration has been replaced? At this time, I still have a working root method working now, so I would like to share it with everyone Also, you can follow this guide to get rid of the superuser App from those android root exploit app and use SuperSU.
In short, this tutorial tells:
1.How to Root Oppo F1s(A1601) with KingoRoot.(Though cloud based root App Kingroot is not working at this period but KingoRoot the offline one is still working)
2.Though KingoRoot prevent you to switch to other superuser App, we can still replace it with SuperSU with few steps, no custom recovery needed.
****NOTE****
There're various version of KingoRoot apk over the Internet, use the APK version I provided at attachment can guarantee there're no unexpected errors.
The script to replace kingo root was based on the one here but with a little modification, I've added a infinite loop for the script because KingoRoot cause a force reboot(soft reset) right after you delete root from the app, I assume its because KingoRoot want to prevent you to replace it. A infinite loop can make sure the file copying action has been done before your phone reboot.
Steps to Root F1s and Install SuperSU:
1.Install android terminal from Google Play: https://play.google.com/store/apps/details?id=jackpal.androidterm
2.Download the attachment, extract the zip archive, you get an APK "KingoRoot.apk" and a folder "rmkingo", copy the APK and the folder to your Internal storge(Sdcard)
3.Use any file management App to open KingoRoot.apk and install KingoRoot.apk
4.Open KingoRoot and click "one click root" then wait it to obtain root
5.After root succeeded, Open previous installed "Terminal Emulator for Android" and type
Code:
su
. Now KingoRoot's Superuser should pop up and ask you if you want to grant root access, allow it.
6.Now change terminal directory to the script folder, terminal type
Code:
cd /sdcard/rmkingo
7.Now execute the first script, terminal type
Code:
sh step0.sh
8.If there's no error on the previous action, Now proceed to execute the second script which is an infinite loop, you might see infinite error message after you executed it, terminal type
Code:
sh step1.sh
9.Now make sure the Terminal emulator is still open and the script is still running in background, just open SuperUser(installed by KingoRoot), find and click "Remove root" in the option of the App.
10.Your phone should be forced reboot now, after reboot, install SuperSU from google play: https://play.google.com/store/apps/details?id=eu.chainfire.supersu&hl=zh_TW
11.Open SuperSU and update su binary file with normal mode and wait, it should finish in 2-3 minutes.
12.Hit thanks(My pleasure)

Hi, I assume you have to downgrade your rom. Find a older version of your rom, flash it via OPPO stock recovery and this method will work.
In my region, Taiwan's newest rom date is 2016 October, so this method work. OPPO might fixed this CVE exploit in their new rom.
The rom I currently use can be downloaded from OPPO Taiwan website, however I'm not sure if it can work on your device, so you might need to find an older version of your region
You can try to get root with older firmware, flash twrp recovery with root app, such as rashr,then once you have twrp recovery, you can flash the new OTA update package, but be sure to modify the update package so you will not loose root after update. However, I think just stick with older firmware will be easier

I made one and got root with A27 , all you need is a twrp and a twrp flashable firmware zip.
Here's what I did,first I found that the TWRP by @BouyaPK did not have the same device model settings in comparison with the stock recovery, so I made a little modification to his TWRP image, now the offical firmware zip can pass Device detection test.
!!Before doing it , make sure you have flashed the modified recovery(the one from attachment) to your phone, official firmware is only flashable via this modified recovery and stock recovery
Download here
View attachment OPPO_F1s_twrp3.0_modified_devicemodel.zip
this is the example with the ota update package (A19 to A27 upgrade package around 150mb via coloros update manager app)
Now lets start to modify official firmware, follow my steps:
1.extract the newest official firmware zip.
2.now open the extracted folder, navigate to \META-INF\com\google\android\
3.find the file updater-script and open it with text editor( I suggest NotePad++)
4.you'll find a lot of lines start with apply_patch(xxxxx), remove the one with this file "/system/recovery-from-boot.p"
5.(if needed) also remove boot image sha1 check, in my case I have magisk installed, my boot image do not have the same sha1 value with stock boot image, so I found the line that checkes boot.img and remove it
6.done the file edit and save the file
7.repack it back to a zip file and sign the package with test keys
How to sign?
1.Download the sign package from attachment
2.have Java installed on your PC
3.Open a terminal at the same location with the keys and signapk.jar
4.terminal type
Code:
java -jar signapk.jar -w platform.x509.pem platform.pk8 my_modified_firmware.zip my_modified_firmware-signed.zip
8.install with twrp and you still have twrp exist, flash supersu zip or magisk zip
above is the way to modify a PATCH zip ota file, if you are modifying a full package, which may be easier,
the full package's update script write full image to phone instead, so you just need to modify the image in the ota package.
all you just have to make sure the new firmware do not replace twrp with stock recovery, so
1.try to extract the image in the package and modify the image file, remove files such as "recovery-from-boot.p" from the image then rebuild the image and calculate the new sha1 value of the new image(CarlivImageKitchen is a good tool to rebuild image)
2.replace the old sha1 hash in updater-script, repack and sign the zip.
3.flash with twrp
4.flash superSu zip or magisk zip after the firmware flash with twrp can get root.

As I mentioned, only the small OTA Update package(smaller than 300MB) extracted from Built in update manager App has the line apply patch.
You are using a full package which is another situation.
If you have the full ota firmware downloaded from official website, you can try the follow steps
1.first make a nandroid backup of the old 5.1, make sure you can always restore your phone with backup
2.flash the official firmware zip with the twrp I attach( if any error occurred,do not reboot ,restore your phone with nandroid backup, also write down the error, and see which image file does not have the match SHA1, calculate and modify the sha1 of that line)
3.if step 2 succed ,do not reboot flash superSU zip file
4reboot, you may have superSU and your twrp may be replaced by stock recovery, use rashr flash twrp back again since you have root

Here's a little guide
1) Put your TWRP, SuperSU and Android 6.0 Oppo F1S ROM onto SD card
2) Use Flashify to flash TWRP
3) Reboot into TWRP recovery
4) Flash Android 6.0 F1S ROM
5) Flash SuperSU
6) Reboot phone and you should be good to go

sim card not recognized!? Sorry I can't really understand the reason of that because I don't have this problem.
Just a thought, maybe you lost baseband? Can you see your phone's IMEI number in settings? If you found null IMEI, that means you have lost your baseband, otherwise that's just something else maybe a small unknown issue, may also be the access point and protocol was not included in the 6.0 rom
If you lost your IMEI, I assume you already did the nandroid backup before, in twrp backup of NVRAM is the IMEI part, you should be able to recover your IMEI with that nvram backup

ok got it to work for a full firmware package here's what i did
1 . downloaded a27 (still 5.1 since 6.0 is not stable according to some)
2. using the twrp above flashed a27
3. flashed magisk
4. flash the twrp image again to make sure that incase it was overwritten by the update
NOTE: i did get an error like unable to mount dev/block/platform/...... it was fine for me

did you try restoring the nvram using twrp as stated before?
and did you wipe your data before flashing?? i think the transition from 5.1 to 6.0 may have broke some things read about it somewhere that wiping was necessary for LP to MM

Any way to delete system files without flashing supersu/magisk

Hi,
i want to perform below things on my mi mix 2 :
1. Delete a CONF file located in /system/vendor/etc .
2. Have stock recovery and do not need root thereafter.
Is there any way i can do that like through adb or something so that i don't have to flash SUPERSU and root my phone. This deletion of system file is only a onetime activity and i do not need root on my phone.
Thanks in advance!
Hey Guys, you reply is awaited please. Whole purpose of above request is that if i root and delete that file, i need to flash full OTA everytime and delete that file again. So if without root i could delete that file, full OTA wouldn't need to be flashed.
you can try with adb in recovery, but you must have twrp

You must unlock bootloader, install twrp recovery, reboot to recovery and you can delete files from filemanager in recovery

stock touchwiz rom for 2017 a5 sm-a520w

so i had an issue installing supersu on my sm-a520 and after searching everywhere for the proper firmware file i could only find firmware files in .lz4 format which odin3 would not flash to the device properly i then found a program that is free called classykitchen which allowed me to decompress the .lz4 files then create a system.new.dat file to flash via recovery so if you have run into this issue i recommend finding classykitchen and installing twrp via odin3 then download the firmware file from updato.com unzip that file then when your starting a new project in classykitchen make sure you put bl ap cp and home_csc all in the new project by highlighting all the files and make sure when its done extracting the lz4 files you select create system.new.dat once thats complete put that file to the sdcard wipe the device for a clean install and flash the file youve just created and bingo your phone will be back to stock other then the twrp recovery which i will say is the best recovery ive used in my mind there is no better.. now that ive explained that i'm gonna try installing supersu again and keep on keepin on have a good one

You shouldn't be installing SuperSU on newer versions of Android. Use magisk instead. Then you shouldn't have problems.

Question Kernel updated, root lost

Hi Guys,
For some reasons, my kernel got updated without any change from me, not sure how this is possible.
Now, because of that, I lost root, is there a quick way to restore root (magisk) ?
Thanks in advance !
Yep. Just download the matching factory image zip for your currently installed build of Android. Then, extract the boot.img file, copy it over to your phone, patch it within the Magisk app and it will spit out a patched boot.img file into your "Download" folder. Next, copy that patched boot.img file back to your computer and flash that patched boot file using fastboot.
That may look like a lot of different steps, however, the process usually takes less time than it has taken me to type this comment, haha. Enjoy your root access =)
