[Q] How to reset firmware in A500

I bought an Acer A500 from a friend a few days ago.
When he gave it to me, i saw that it has a password that he can't remember.
What can I do to reset or update the system?
Please help.

You can do a factory reset. But then, all user data will be erased.
Turn tablet completely off. Turn off hardware screen lock switch. Keep holding Vol+ and press power switch until tab vibrates. Now turn on and off screen lock repeatedly, until there is coming the first erase message on screen. Then tab is doing a factory reset, and after that, you should be able to enter the OS again.

I tried but didn't work, it starts normally and asks for the pattern

Have you senn the erase messages on the screen? If not, you did something wrong. The timing with the buttons while doing factory reset is important. It can take some tries to succeed.

No messages =/
Just to be clear: i have to put the screen lock switch in red before the process? Than I hold Vol+ and Power, and after the tablet vibrates I turn on and off the switch?

No. Red is on. You have to put it off.

Didn't work again =/
I also tried with Vol-

Then look here.

Now I could enter the erase mode, but didn't reinstalled. Must have an update.zip in SD card?

Your tab should be unlocked after factory reset. No need to have an update.zip.

[Q] Soft Keys stopped working after KitKat upgrade

After I upgrade to Kitkat, The middle "home button" soft key is not working. The pull down notifications draw is empty and the settings icon in the top right does not respond, and holding down the power button only shows "Power off" not the full list of menu items for volume/vibrate/silence like normal.
Any ideas on how to FIX this or is a full wipe and restore required?

Any help

I had problems similar to this but it was the back button not responding.
It only happened when I used a custom ROM by mahdi(think spelt correctly)
I had to install ROM twice to get buttons working.....I an now using purity ROM and not had any probs since installing.
Are you on stock? backup then Try reinstall ROM or use custom.

Yes I am on stock. I will try to reinstall it again.

It is working now. I reinstalled the stock ROM again

Screen does not lock or turn off, need help.

I can not turn off or lock the screen anymore, neither by pressing the power button nor by using a lock screen app.
I changed nothing, it just stopped working.
When i longpress the power button, the shutdown menu shows up as usual.
Even after restoring an older backup, the problem still exists.
When i wipe everything and install my rom again, the normal function is back.
Sure, i could just reinstall everything but i first want to ask if somebody knows a fix for this issue in case this happens again in the future.
Thx for helping

Thats not correct. From complete turned off phone hold power and vol down.when lg logo appears release and instant hold again till factory screen.3 x power and then recovery comes. Dont know the behavior if a usb cable is plugged in on pc.

I can´t make hard reset on my G2

First, I apologize for my bad English
I screwed up when I had to restore from titanium backup and now I can not get into my phone. I get "com.android.phone stop working" and the only choice is to press ok and then repeat it over and over again.
Probably it would resolve itself with a hard-reset. But it dosent work. I'll have to try serval of times but i cant get into That fashion. Everytime in the press volume down and power button nothing happens. If the note relase them it just start over and over again.
Is there anyway to make a hard-reset anotherway, maybee from a connected PC or something? At this moment my phone is completely unusable.

You have to press volume UP and power button to make a hard-reset.
