@zdzihu & Bin4ry

hey guys just brainstorming here... if u guys are able to make/flash custom/modded system.img can we use the chargemon 'hack'/'boot-hijack' to give escalated privileges to certain files before the system/main OS boots up? may be install busybox links too?

sorry if this was stupid...
[Xperia Arc Q&A, Help & Troubleshooting] zdzihu:
It's even easier. Successful flash of custom system.img / boot of custom boot.img means the phone is *poof* rooted. Just like that. No hi-jacking, no hacking - we take over control, we do whatever we want.

The problem is that the phone won't accept my kernel images. We will see about system.img tomorrow when Bin4ry is ready.

[Xperia Arc Q&A, Help & Troubleshooting] Step666:
I've tried SuperOneClick (the first link), both v1.7 and v1.8, using both the psneuter and RageAgainstTheCage exploits in v1.7 and I tried both before and after unlocking my bootloder - no luck, it freezes/loops.

Same with z4root (3rd link), tried both before and after unlocking the bootloader - again, no luck, it just hangs.

As for the other method (2nd link), I hadn't tried that prior to unlocking the bootloader because I wasn't aware of it until now but I just tried it and it doesn't work.

No, sorry.
