Root adb permisions denied solved (downgrade stock 2.3.4 mt4g)

ill start out by saying i take no credit for the guide im posting a link to. give credit where its due. i however take full credit for the changes i had to do to make it work on the newer mt4g that comes stock 2.3.4

heres the link to the guide i used:
[GUIDE] Downgrade G2 (2.3.3) & DZ (2.3.3) & mT4g (2.3.4) w/ S-ON to Stock Froyo - xda-developers

Gaining temp root
in step 1 instead of unzipping files to adb unzip to root of phones sd card then take phone out of mass storage
in step 5 instead of using: adb push fre3vo /data/local/tmp
use: dd if=/sdcard/fre3vo of=/data/local/tmp/fre3vo

Changing Version Number to Allow Downgrade
you can skip step 1 as long as misc_version is on root of sd card
in step 2 instead of using: adb push misc_version /data/local/tmp/misc_version
use: dd if=/sdcard/misc_version of=/data/local/tmp/misc_version
for some reason they removed the version number for mt4g from the guide i used the version number u need to change it to is 1.17.531.2

Downgrading
instead of using push command turn on mass storage and drag and drop PD15IMG.zip to the root of sd then turn off mass storage


other then those couple of changes i followed the guide to a T
