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..

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.

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.

I can't remember which one, It's either Lightflow or LED manager something. Nope, the LED won't respond with the settings in whatsapp, fb messenger etc.

Rooting won't change ur launcher GUI - if that what concerns u. If only gives u access to root so u may do things otherwise not possible w/o it.

One click root as 'zerohunter' guide earlier was what I used and it really easy and most important it works! U will get rooted in no time and install ur TB to restore our apps / data.

My main goal to root is get TB other than few nicks rooting features.

Just an advice.. Once root flash TWRP recovery and do nandroid backup and u r practically safe to move fwd.
Mike, i know CWM got issues but TWRP recovery works perfectly. Im on twrp and able to nandroid and even partition w/o sweat. It even came with SuperSU - with One Click UnRoot! option. This not tested but my finger itching wanting to press it.. duno why?

Now I believe gave enuf reason 4 u to proceed rooting ur phone. W/o root access, ur phone considered not fully utilized lar.. Let me know if u need more convincing.. Ha.ha.

FYI, just like my prev A830, my daughter also use this phone to play games etc. So she needed her games data backup and restored. Now she really have a hard time draining juice from this phone as compared A830.. Ha.ha..

One Click Root > Flash TWRP via Mobileuncle > Do backup via TWRP > RePart
Follow guide by ZeroHunter (OneClickRoot) and Garytanyh (RePart). They posted these guide on early page 10-15 of this thread.
TWRP search for Life v05 (can't remember but sure u find asking pakcik Google..)

Just an advice.. Don't simply flash any ROM w/o 1st reading thoroughly. Take time knowing what I'll be flashing. Rush² and u might end up like me.. Ha.ha. 

Tried but cannot....

icc... a lil exp than the 4gb ver 
still cheap though!

no problems so far. smooth for me 

I would love to know about this too, and also, have they fixed the Contacts Manager bug(can't add contact after keying the number, can only add after making a miss call). Thanks
