Right. Im at this step:
adb shell mount -o,rw /dev/block/platform/soc/7824900.sdhci/by-name/vendor /vendor
but all im getting is:
At line:1 char:19
+ adb shell mount -o,rw /dev/block/platform/soc/7824900.sdhci/by-name/v ...
+ ~
Missing argument in parameter list.
+ CategoryInfo : ParserError:

) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MissingArgument
the rest works but im getting a bootloop at the logo
Edit:
adb shell mount -o,rw /dev/block/platform/soc/7824900.sdhci/by-name/vendor /vendor <=this doesn't work; my command prompt doesn't register this as a command.
adb shell mount -o rw /dev/block/platform/soc/7824900.sdhci/by-name/vendor /vendor <=this works but I still get a boot loop.
the difference is -o,rw and -o rw
I have the XT1922-9 btw.
I pretty much have the same problem as michelmmoraes
