2010matej · Mar 10, 2013

Hi guys!

I found easy way to root our Xperia J with latest JB 11.2.A.0.33 or 31,21 update!

What you need:
1. Unlocked bootloader --> http://unlockbootloader.sonymobile.com/
2. Flashtool --> http://androxyde.github.com/
3. Usb cable
4. Enabled USB Debugging + Non market apps
5. All drivers installed

Let's begin:
1. Connect Xperia J with USB cable to PC
2. Download this: http://www.mediafire.com/?nr4oxprop5c252o
3. Copy "root_xperia_signed.zip" file to sd card (ext...)
4. Disconect Xperia J and turn it off
5. Launch flashtool
6. Hold volume + button and connect phone with usb cable to pc, you'll saw blue led light (this mean you entered to Fastboot mode)
7. Download this: http://www.mediafire.com/?i6zk4rarrzm9j3s
8. Copy "boot.img" file to flashtool/firmwares
9. Click on lightening icon in flashtool and click fastboot mode

10. Click "Select kernel to Flash" on right side in flashtool

11. Browse and choose "boot.img" , flashtool will automaticly flash this file
12. Turn off phone after flashing
13. Turn on phone,when you'll see blue light at bottom phone not the small blue led up, start pressing all volume down - button.
14. If you succed,you'll enter to CWM recovery,click "install zip from ext card" and find "root_xperia_signed.zip" file and flash it.
15. After flashing,click reboot system,but don't wait for reboot,just take battery out for few second and put it back
16. Now download this: http://www.mediafire.com/?pa13gp9yknugy1e and copy "kernel.sin" file to flashtool/firmwares
17. Follow step 9 and 10.
18. Disconnect phone and turn it on!
19. This is it,click THANKS button if helped and Enjoy!

Why to read? It's not the same

I've already tested. it's works

:good:

diablo_ger · Mar 10, 2013

works perfectly!

thanks, this worked perfectly for me.

I downloaded the ROM via SEUS, extracted the FTF file, flahed it and got root with your howto.

Glad to hear

adfad666 · Mar 11, 2013

lol what?? if you want to unlock the bootloader then this is way too complex. You can simplify as follows:

Unlock bootloader
Flash CyanogenMod kernel
Flash SuperSU
Flash stock kernel

Done! :silly:

Problem

My Xperia perfectly rooted, but it seems that the 3G is not working on the phone, can anyone verify whether it is caused by the rom?
I tried all methods (recheck APN, disabled Wifi...) but can't seem to get the 3G logo to appear in the status bar.
Have to resort to Wifi in the meantime, if not the problem of the rom, then I guess I have to perform a reset.

Nope, fixed, changed the APN name after googling.
Root works great!

You must unlock bootloader first.

My bootloader is already unlocked (according to service menu, showing a "YES"). But I still get that!

Need enlightenment!

Yes means its unlockable, not that it is unlocked
