A new easy method is introduced, lets follow another thread, thank you for supports

http://forum.xda-developers.com/show....php?t=2186368


--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Requirement;
Rooted 4.0.4 with locked bootloader (Rooting)
CWM for Xperia V ICS (CWM)

Make a backup copy that is compatible with JB
1. Flash stock JB rom in CWM (XperiaV-JB.zip)
This step is probably!, not required, yet it is to be checked. Firstly I tried without this step and my phone got continuous reboot. When you flashed the stock JB rom do not reboot the device and proceed to step 2.
2. Flash JB rom in CWM - Xperia V Supersport JB is recommended (Xperia.V.Supersport.JB.V1.1.zip)
You can use another rom, but I haven't noticed any problems with this one so far. Do not reboot the device and get right to next step.
3. Flash fix for CWM (Xperia.V.JB.CWM.Fix.zip)
Do not turn on your phone. You can push reboot in CWM and when the screen is off pull out the battery. Only then the next step.
4. Flash stock kernel 9.1.A.0.490 FTF in Flashtool (LT25_SXV_Stok_Kernel_9.1.A.0.490_Dogsly.ftf) thanks to, Dogsly

After rebooting, your phone will be in android 4.1.2 with SU in locked bootloader,
If you have applied fix for CWM in step 3, you can still enter CWM but press power button (not holding) instead of volume button.

If you are in JB with root already, you can install CWM for xperia T v2 made by davidmarco. (Xperia.V.JB.CWM.Install.zip)
Install step refers to ClockWorkMod 6.0.1.2 for Xperia T/TL/TX/V
Enter CWM in JB: After blue LED appear, continue press power button (not holding)

Sv: [Root] Xperia V with locked boot loader
Nice guide, thanks!

Step 1: I read there is no Gapps in that ROM?

Step 2: do you mean flash kernel.sin and loader.sin?

And tft is picture format, maybe you mean ftf? :-p

I think its better you write: flash Jelly Bean ROM instead of system, its confusing (system.sin)?

Anyway, good finding.

This firmware TRIMMED-LT25i-SOL21_9.0.F.0.195.ftf as I understand I am sure is for the Xperia VL and I tried it, keep getting to Xperia logo then reboot it everytime and it ask for the decryption key so what is that please?

I already Jelly Bean locked on my phone so can jump to flashing with with above firmware again concerned it might keep rebooting or I do I need to downgrade to ICS firmware first?
