[G4 General] asaf400:
LATE EDIT: Figured it out, Read bottom edit..

Yes, and i'll do it without looking in the guide, so it'll be like i've just did it.. (4th time already after KDZ - still no go...)

Background: Win8.1 x64 [Didn't have vc++ problems], LG Drivers install from this thread

Phone Background: H815 Europe, Came with 10a, OTA updated to 10b-EUR-XX

*ALL the attempts had the same outcome - no root, I'll clearly at the end of the steps...

1. DevTools > Enable ADB

2. DevTools > Enable OEM stuff (among the first options [was done in TK's Video])

3. Verify adb works (adb.exe devices) and accepted my PC

4. Ran this command:

adb.exe push busybox /data/local/tmp/ && adb.exe push lg_root.sh /data/local/tmp && adb.exe push UPDATE-SuperSU-v2.46.zip /data/local/tmp

5. Shutdown the Device > Enter Download Mode

6. port.bat output is: Diag1 = COM4

7. Entered DownloadMode 'Shell' by using Send_Command.exe \.\\COM4, Verified with command 'id' which returned: 'uid=0(root) gid=0(root) context=u:r:recovery=s0'

8. Used the dd Command that 'fits' my H815 which is *

dd if=/data/media/0/<rootedsystem.img> bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0

*

8.* This step was done with numerous system images, those included:

8.* a) My original 10b image, after it has been through the 'autoroot' method inside an ubuntu VM, with root permissions (the method mounts the image, changes stuff so the image would be rooted, saves and renames the .img file)

8.* b) 'H815 10B Vodafone Germany' Image on the 2nd post - this one had a weird result, it had done 'Android Upgrading' for all packages (apps), BUT didn't have any vodafone app?? (ROM without Provider Bloatware - That's fishy...)

Note: Broke exFAT! (Was empty though :) )

8.* c) 'H815 10B Germany EUR (Open)' Image, again on the 2nd post right under Vodafone, I've though this one was going to work for sure, alas, it didn't :(..

Note about this one: again went through 'Android Upgrading' for all packages, also the OriginalPoster of the Image included both his unrooted and rooted images with their MD5 [Thanks m8],

I've compared the MD5 for my MD5 (for both rooted and unrooted images) and it didn't match, which made me get my hopes up as I though that my Image is just harder to root..

Now for the results I've promised (Again SAME for all attempts):

SuperSU App is INSTALLED! (although it's asking to update su binary each time..)

When testing root with Terminal Emulator typing: 'su' Results are a sort of hang\wait, it's doing nothing, but it does not get back to prompt..

When testing with a 'root checker' similar result like Terminal, The check just keeps going never returning a result... and timesout after a while...

Mid write Edit:

FOR **** SAKE!!!!

I HAVE ROOT!!

As I worte this I've thought just **** it, let's just let SuperSU update the Binary, no damage done if it fails..

and Vohala!! I'm Finaly ROOTED!!! whoami? i'm id 0 !!

AutoPrime, m8, Please Please Please Please Please Please Please Please Add that final crucial step, LET SuperSU Update the Binary

I feel like I've bought a new car, and revved up the engine to the max just to tune it, and by doing that lower it's life expectancy

Now alloy that to the MMC, the Flash inside the phone... :(
