Oh you want to learn. I thought u just want to repair your phone only. Then you should try what xMika post. I believe someone did give a link for pc driver in early of this thread. Good luck 

when any of you got the 8GB... please post your Storage print screen, curious to know the partition...
if what i'm expecting, then will sell mine and get a 8GB...

Battery more less is same.
Difference is u got vanilla android. Coming from nexus,i prefer nexus stock ui

Kemek,
Ady done as xMika suggested but it still can't pass lenovo screen. Tried many times reinstall driver and it did install but phone still refuse to connect to PC. Btw, how could I not have the driver in pc since I root using same pc? I even tried using diff cables just to be sure its not the culprit. I also familiar using Flashtool.

What puzzle me pc & phone now don't wanna talk to one another. Wondering if these 2 got big fight of something..

Someone just suggested me try something that didnt cross my mind b4 this. hmm... will try do later 2nite. Will update...

From what I've seen on the 8GB S820, it's 2GB ( internal ) USB storage for Media and 4GB for internal Storage (for softwares etc ) the other 2GB is for Android OS like other Lenovo phones

if u are worry about the warranty, there's no need to worry, once u reset the phone it will back to stock condition without root if u need to claim warranty from sc

just sharing

P780 one click exe driver installation

one click rooting

red n yellow only...
sometimes red n yellow turn on together.. u will see mix color of the  LED  light..

it is official. i will get my p780 8gb version on friday. 

There are few bugs in the software of the phone:

1. You can't save a phone number by highlighting and save from the popup menu. You can key in the name but when you hit save nothing will happen. The only way to save the number is to go to contacts, create new contact and paste the number there, then you can hit save. This is super frustrating especially when you want to be quick.

2. You can't share pictures from supergallery to wechat moments. You have to go to wechat>moments>that camera button on top right and choose photo(this is soooooo like iOS. Lenovo wants to copy iOS? Later Apple sue them how? ). From gallery to FB messenger, messages, whatsapp, wechat messages, works fine. Only wechat moments.

3. Notifications LED won't respond to 3rd party apps. 

4. Will add up later if I can find more bugs.
What? What?

that is notification widget, part of status bar, and status bar is part of SystemUI. you can try change ur SystemUI with same (other p780) systemui. beware, this is system file, do it with ur own risk

Fixed it, just use CWM or Link2SD clear Davlik Cache and reboot *takes sometime to boot.

12hours SOT? That's superb, how's the brightness setting?
If u change the setting now, some apps may not work anymore, what I did is I do all my backup, factory reset the phone, first thing after it booted, I change to write to external storage then install and restore all
How about try on another pc, a fresh pc that never connected the phone

feiton shop?? or which shop lolz

how much 8gb p780?

My LED Notification lights (near the earpiece) is not blinking even I've already enable in the setting. However, the LED notification (near the earpiece) is always shown up in green color and won't blink for notification.
Is't normal? The light will only change to orange color when charging    

where to get?

By default, it won't blink, it'll stay on. That's the case with mine. Got it to blink using third party apps, but can't change colour.
