Re: {GUIDE} How to Root Xperia™ Smartphones

Hello, just my first time to try this out.

pls let me know if my understanding is correct based on your instruction.

my phone is xperia mini st15i  4.1.B.0.587

- download flastool

- download 4.1.A.0.562 kernel then flash

- download rooting tool then run (root)

- download 4.1.B.0.587 kernel then flash again

is this correct?

Re: {GUIDE} How to Root Xperia™ Smartphones

i noticed that the link for mini is pointing to this file -> ST18i_4.1.A.0.562_kernel

are ST18i and ST15i have compatible kernels?

i can't see any .562 kernel specific for mini either.. i found GB 4.0.2.A.0.62 on other sites.. is this compatible for rooting as well?

Re: {GUIDE} How to Root Xperia™ Smartphones

rainybhoy As i said on the top in my guide

All has been tested so don't ask if it would work or not.

This post is for 2011 Xperias. For 2012 Xperia See 1.

But still, i'll reply to you Slightly smiling Face

Just follow the steps blindly and you would get nothing but a rooted phone. We flash 4.1.a.0.562 kernel just for rooting and in the end flash the original kernel meant for the device Slightly smiling Face

Buddy , screen would remain back. All you need to see is if the led or capacitive buttons are lighting up ?

If they are lighting up then just run the rooting toolkit Slightly smiling Face

Didn't you mark Usb debugging and MSC mode ?

Yeah, flash 4.1.B.0.587 kernel for your phone or just reinstall the software  on your phone using SUS or PCC

Re: {GUIDE} How to Root Xperia™ Smartphones

rainybhoy Mahn you scaring me .Anguished Face PCC is buggy though.

Take the battery out and reinsert it. Then do not switch it on, just run SUS and follow on scren instrcution

And yeah, do not connect your phone until you're asked to do so by SUS
