Re: {GUIDE} How to Root Xperia™ Smartphones

Hi!

I've got a problem, I'm trying to root my phone (mini pro, SK17i), but something is wrong. I think the problem is in the FlashTool, every time I try to use this software, I get the same log:

02/029/2013 19:29:24 - INFO  - <- This level is successfully initialized

I did a clean installation of the OS by SUS, and then tried to run this guide, but always get the same problem ...

Of course, I did all these steps:

Go to settings > Security > Mark  "Unknown sources"

Settings > Developer options > Mark USB debugging

Settings > Xperia > connectivity > USB connection mode > select MSC mode

What I find strange is that I have managed to root this cellphone before, and now I'm having this problem! Any help please?

Re: {GUIDE} How to Root Xperia™ Smartphones

satyanreddyg i suggest you try on different PC

NashTaufer That's not possible friend. However you can root your phone without having the need to unlock the bootloader.

You wan't to root it ?

pumabr But that logs seems to be fine. Ignore the error and proceed with rooting toolkit.

Are you able to do that ?

RaiderColombia HAHA Smiling Face with open mouth & closed Eyes

I could feel how happy you're

I'm always here to help, keep going Slightly smiling Face

Re: {GUIDE} How to Root Xperia™ Smartphones

pumabr Then i guess the kernel has not been flashed properly

Did you remember what version of flashtool you used when you rooted earlier ?

Maybe using that version would work now.

Otherwise i would just say try with other PC. Disable antivirus and firewall during the process

Re: {GUIDE} How to Root Xperia™ Smartphones

Thanks Nabeel! The problem was the version of FlashTool I used (the latest, 0.9.10.1). I removed this version from my computer, reboot, installed version 0.8.0.0, then the 0.8.5.0 update (just as I had done before), and this time everything went without any error. Again, thanks for your help, without you I would not know what to do anymore!
