Xperia Arc forgot lock pattern with USB debuging is off

hanoidesign · Mar 12, 2014

Hello,

Unluckily I forgot my Arc locking pattern with USB debugging off. So I can't do FlashTool with Flashmode.

I tried method here:

but it does not have 'Customization Settings'.

Is there anyway that I can flash a system image via FlashTool Fastboot mode or any other better way around?

Looking forward to your advices.

Yes, you can. You don't need USB debugging for flashmode.

It's not gonna help you, the lock data is saved on /data partition. Factory reset will remove the lock, but it will as well remove all your personal data.

Thanks for your advice, but I must be doing something wrong. FlashTool won't allow me to proceed on Flashmode with USB debugging off.

Here it keeps Wait for Flashmode...

I am missing something?

Make sure drivers are installed. Phone has to be turned off, then hold down Back button and connect USB cable.

You're life saver!! Worked at second trial.

I found good reason to flash to ICS anyway, and rooted it. Now I tried x-parts to have Recovery but x-parts said CWM installed OK but I tried reboot from x-part or press volume at boot, it still boot normally.

Any thought?

I've managed to get CWM Recovery working by removing x-parts and install CWM from the old cwminstaller-v1.apk that I found. Yes the latest CWM version is not working on Arc in my case.

Hope this helps.
