thats exactly what it means. It cant mount /system as read/write so it just errors. and then the rest fails

[jburchii]

I wish I could help. If there is a way you could explain to me what to look for aor how to even access the program I would try to help.

[SPJESTER]

right click the .batch file and edit with notepad++ or something. Its just adb commands

[jburchii]

i just got this, and I AM connected via USB and have debugging enabled... wierd.

I figured out what the first problem was - when I am using my razr as my router via easytether it will NOT recognize the phone.....

[jburchii]

Hmm.......seems that it is unable to write to the file system? How was this handled for the ICS root?

[SPJESTER]

same kind of way. Already been tried

[baciar1]

They locked it good still no luck

[jburchii]

So the only problem is getting it to be able to write the files in the system folder? Is it possible that they fixed it so it could not be done?

Looks like I keep ICS 4.0.4 on my MAXX for now. Thank goodness my Nexus 7 is coming in tomorrow.

[jburchii]

How do you go about trying to find an exploit? I understand making changes to the batch file, but is there a way to get into the file from your PC? I notice that when I connect my razr to my PC via the USB cord I can't locate any kind of system files - only the internal and external SD cards.

[marksibert]

You won't see the phone's internal filesystem as a mounted drive in Explorer. The only way to manipulate the internal filesystem is through ADB. You use "adb push" to send a file from your pc to a directory on the phone.

The issue is that the /system folder on the phone is read-only. You can only make it writeable if you have root access. And you can only gain root access if you can write a file (the 'su' program) to the /system folder. So it's a catch-22.

The various root exploits trick the operating system into giving temporary write access to the folder. Once you have that, you can copy the su binary where it needs to be and do some further changes to get permanent root.

If you read the batch file, you can see it's just a bunch of 'adb' commands.

[Mr. Orange 645]

That's one of the best explanations of how root is obtained I've read. Never understood HOW it happened, just always took for granted that it DID happen...until now. I just ordered a GNex to tide me over til we get this bad boy rooted again. Keep up the good work, all ye who are far more talented than I.

[Mr. Orange 645]

Quick question then I'll stop thread jacking. Does having the boot loader unlocked (I.e. the Gnex) make it easier to root, or are they two separate issues? Do you still need to find an exploit with the boot loader unlocked, or does it leave /system open to write? Been Droidin' since the OG Droid but never really learned how root is achieved. Like I said I always took it for granted.

sdcard test2 is failed...

Thanks! That helps a lot.

So, what are the possible ways to "trick" the system to let you write a root file?

Will this help you guys?

Someone on xda posted a root method for the 910 China I wonder if something in that method could point us in the right direction



Edit: it is in fact for the jelly bean. Dnt know what the difference is besides it being a gsm phone. But wouldn't think the securities would be that different
