No root yet, but I figured it out!
If you download the stock firmware. I believe this is where I got mine from:
CAUTION!!! Apparently, this phone may have 2 variants using the same model number! See link.
Make SURE you get the right file for your device:
Go into your "device info" and look at the build number. The two links in the above site show the build numbers. Make sure you get the right one! I happened to get the right one by dumb luck!
Now, extract the zip using 7-zip. Then, right click on each file individually and use 7-zip to extract them.
In any case, one of the files should have boot.img in it. I found boot.img in "AP_S727VLUDU1AQB5_CL10551307_QB12606263_REV00_user_low_ship_MULTI_CERT.tar.md5"
I have transferred the boot.img file to my phone and am attempting to patch it using magisk. (Which I have installed the apk.) No root, just the apk tool so far.
Magisk did patch the boot file and produced a "patched_boot.img.tar" file. Supposed to be ready to flash using odin.
Where do I go from here? Can I simply flash it back, as-is?
Do I put the updated version back into the same .tar.md5 file and then flash it?
I have done this and I have a new Boot.img file that's a bit larger in tar.md5 format. Apparently, odin is supposed to be able to flash this directly to the phone?
I'm very close, just not quite ready to pull the trigger. Anyone brave enough to throw caution to the wind and pull the trigger? Download ODIN and go for it. Of course, let us all know how it goes.
The patched boot.img file is 11.12mb. Original file was 10.86mb. Sounds reasonable...
If someone is willing to flash it using odin AND tell us if it worked and how to do so step by step, then I will gladly share my patched boot image file. Just send me a means to upload it. Of course, I'm not liable for such exercises.
I'm going to read a bit more before I jump in.
NOTE: all of this assumes the download of the stock firmware is really the correct firmware for our phone and that the patch worked correctly. I'd feel better if someone else had already done this.
