For some reason, after I finished rooting, my device shows kernel 2.6.32.9-perf BuidUser@BuildHost #1

How do I get it back to normal?

Here are the link for post #3. For those who don't read through previous post.

This tutorial is for 4.1.B.0.587 only!

1) flash the 4.1.B.0.431 kernel:

note: you might get errors after the reboot, don't worry, this is normal and step 3 will fix that.

2) root your Arc/s with DooMLoRD's tool:

3) flash the 4.1.B.0.587 kernel

Rooting my .587

Thanks again, but those instructions relate to the LT18i, mine is the LT15i.

I already have the DooMLoRD tool, which I used to root my previous build of ICS (431).

I just need a simple step by step that relates to LT15i and 587 build installed (and whether I have the right files - see my previous post)

i have these ff. files which im not sure if they are correct:
LT18i_4.1.B.0.587_Kernel
LT18i_4.1.B.0.587_Kernelonly
1_lt18i_4.1.B.0.431_kernelDowngrade
and the rooting toolkit!

would that be all i can need?
please help i am little bit confused 'coz i also have downloaded a file which is 200mb.
help please

Do you have Flashtool? Flashtool file can get from: http://androxyde.github.io/

If your phone already in 4.1.B.0.587 firmware, no need flash stock 4.1.B.0.587 firmware. If not, you need flash 4.1.B.0.587 firmware before root it.

Flash 4.1.B.0.431 kernel using Flashtool.

Hey guys,

Trying to root my arc cause I dropped my s3 in the pool:(

Anyway, Im not a noob when it comes to these things cause I rooted and flashed my s3 and s2 before but im having problems trying to this phone

I have the LT15A,and build number is 4.1.B.0.587.

So im trying to root so I can install cwm and another rom. Following the instructions above:

Flash 4.1.B.0.431 kernel using Flashtool.

Arc kernel only: https://www.box.com/s/pjgm3evqsc29xieoatdp
Arc S kernel only: https://www.box.com/s/ya3kd7yvdp6d5pc6pp9c

Done. your phone should be rooted now.

I can get passed step 1, with a confirmation in flashtool. Afterwards my build number is the same, however i read it doesnt change cause we are flashing a different kernel. So next I try and root using Doomlords rootkit and I have all these read only errors at the end.

Thats what I get near the end.

Any ideas?

Thanks

Edit: Also checked out the third post where it says use kernel .562 which I have tried as well and get the same results. Not sure where else to turn to
