--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
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 (View attachment 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. (View attachment 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)


Successful root with permission to mount system writable

Thanks Emberlificote for adding the details : )

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?

 

[soncarl]

why are people always said tft not ftf? I have read a lot of that tft. I'm just curious or maybe I'm the one who is ignorant?. Sorry for the off-topic

Step 1: Yes, maybe i upload the stock one later

Step 2: Yes, sorry for the mistake

maybe the step not so clear, but im a bit busy right now, i will edit the post and upload the screenshot later

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

Anyway, good finding. :good:

@datagubben have you manage to root your V? using this step? can you also create a step that is more clearer thanks

A request to a clear simple step guide instructions how to root the xperia v with bootloader locked please.

 

[datagubben]

Edit: Use OP instructions.

Is there gapps?

 

[Darkfunnyguy]

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?

I have set permissions but what should I rename it to?

 

[chansom]

Just updated the steps with Xperia V Supersport Jelly Bean rom recommended as wifi function well!

I get continous reboots after following these steps. Supersport JB and cwm fix followed by stock jb kernel.

´Tried twice now. (had to follow 4.0.4 root for locked bootloader again before 2nd time) Very annoying.
