How to get and mod System.img Android M ZV9

[Tctien342]

_Download this Zip file and extract it : https://drive.google.com/file/d/0Byybyd_nA78MRjJTdWVtaFVyaFU/view?usp=sharing
_Install Ext2Fsd and osfmount
_Now use WindowsLGFirmwareExtract to extract system.img from ZV9 TOT File ! (You have to Merge all system.img file after extract it to get the real one )
_Run Ext2Fsd and use osfmount to mount System.img in window (Uncheck Read-Only drive)
_Now you can mod this system.img and flash it through Send_command like ZV6!

Will this work for ZVA or is it ZV9 only?

Yes

it will work for all system.img but we dont have ZVA TOT

Really the only point of this would be to debloat the system, or install apks to system. Not much else you could do though.

How do you install apks as system because i really want to install nova launcher on this probably distrubute it also and debloat it

Would this even work? Wouldn't modifying the system.img change the checksums. which would be caught by our locked bootloader and cause boot issues? Hence same reason we can't use send_command root injection?

 

[Tctien342]

we can delete and add app to system.img but have to set right permission !
i have modded init.qcom.post_boot.sh file in etc to set that in boot !

You just inject it to /system/app and set permissions to 0644.

can this be used to inject root ?

the script on the bottom has a section:
#Try to add Root
chown -R 0:0 /system/app/SuperSU
chmod 0644 /system/app/SuperSU
chmod -R 0755 /system/app/SuperSU
.......
Did it actually work ?
(Please tell me it did )

Isn't there a way to dd/extract system.img from ZVA phone?

 

[Tctien342]

Root dont work !

I have wrong somewhere so can't active root !
I think we can extract system ZVA by dd but can copy it to PC ? (LG Secure ?)
But we can up back to ZV6 and copy it with root ?

But root files are there? This is great news, it means we just have to figure out what files should go where for proper Marshmallow root. Maybe looking at custom rooted ROM?

do you think install script from supersu for Marshmallow can be called from init.qcom.post_boot.sh ?

Wait can't we also disable DM verity or whatever that's called that's blocking root as well via permissions?

I thought dm-verity protects partition, so if the root files are there and it's not complaining on boot, dm-verity is not an issue.
But the more i am reading the more it looks like you can't root marshmallow without unlocked bootloader

 

[Awesomeslayerg]

I checked there are no files with that I manually added them let see if my thing boots if not ah well

so it boots? can you start an adb shell? do you see su binary? does it have right permissions? can you run it from the shell?

I couldn't set permissions but the files are in there.. I just nuked my laf partition so there's no way for me to continue testing on this device but thank God I have an OS installed.. I guess I'm stuck on this forever now
