Is there any way i can upgrade to jellybean using its Firmware FTF file by flashtool . i try to upgrade throught jellybean ROM two times but both times my cell got softbrick . i wanted a working verison of jellybean . Does i have to upgrade Kerner to ??
There is no firmware for the Miro to upgrade to jelly bean. The only way to do it is to unlock your bootloader, flash a jelly bean kernel (from the custom ROM you want to use) and then flash the custom ROM.

The latest official OTA from Verizon will put you at 4.1.2
Flashing one of the custom 4.2.2 roms is an option.
I recently upgraded my xperia J to the official 11.2.A.0.2.1 (4.1.2) firmware but i kinda want 4.2 on it now..the problem is i cant seem to root it on the current firmware...is there any way i can root it without downgrading.apparently u need a rooted device to downgrade and i cant root..so im kinda stuck.,
You down grade by flashing a stock firmware ftf file with flashtool so you dont need root to flash stock roms. I don't think there is a 4.2 rom for xperia j bro. there are root tutorials in general section for rooting jb for locked & unlocked bootloaders moke sure you follow the right one.
Hi,
My xperia s got the official Sony update to jb 4.1.2 and (ofcourse) I lost the root.
Is there any way to root my device again?
Bootloader cannot be unlocked!
Tried Bin4ry v30, but no result!
Can I flash from jb 4.1.2 to jb-prerooted? (bootloader cannot be unlocked)
Can I downgrade to ics and than upgrade to jb-prerooted?
Hope somebody has a suggestion/answer.
Thanks

How do you have 4.2.1 when sony never released it
Sorry, must be jb 4.1.2 (6.2.B.0.200)
OK, this is what I did.....
1 Use Flashtool to downgrade to ICS
2 Install RecoverX (FIXED) for ICS
3 Copy JB Prerooted to sd-card (don't unzip!!)
4 Reboot in recovery and install JB-Prerooted
5 Have fun!!
Thanks to everyone who made this possible.......:good:
