[Q] factory reset without power button (and without lockscreen password) - Galaxy S III Q&A, Help & Troubleshooting

I've bought an used replacement main board for my s3...
The problem is: It came without the power button. I managed to turn it on by pluging in the battery, but it has a lock screen pattern set.
Anybody have any idea how can i bypass the lock screen or factory reset the phone?
I can't enter in the recovery mode using the key combination, because i don't have the power button... And I can't access the system because the screen is locked.
I can enter in the Download mode using a jig. Can I use some tool to reset the phone in the download mode?

remove pattern lock of Huawei G525 with out using OS

After two many pattern attempts, there is a sign in google account request to unlock the phone , I've tried all my google accounts it seems none of my accounts are synchronized .
one way to get away from this problem is reset factory - I need my data and I don't want to lose them - and another way is removing key pattern by root access. unfortunately my phone doesn't have root permission access and I started to root it using Adb and download mode.i followed some instructions that I found by googling the most nervous problem is the bootloader doesn't load (I tried to hold + volume key and power key or holding - volume key and power key or holding + and - volume keys with power , even back key with + volume key and power!! but again sign in page for unlocking pattern came! )
There is another problem too, if my bootloader is lock how can I found my product Id and other stuff that is needed .
I can see my device when I write adb devices in Cmd but I don't know usb debugging is on or off. my phone is Huawie G525-U00.

If you can boot to recovery mode with a button combination, do that and select factory data reset.

I try combination of buttons too (volume Up with power or volume down with power , ... ). I searched in Google how to enter to recovery mode for G525 huawei and hold those buttons but nothing happens.
always this comes:
the page that request username and password for signing in
(I wanted to attach image but it seems I can't )

Help: Can't factory reset t-mobile Galaxy S6 Edge

Hello,
My wife just bought a Galaxy S6 from a friend of her and we are trying to factory reset it.
If we do it from the menu the phone just turns off and when we turn it on again all the data is still there.
If we try using the keys before turning it on (volume up + power + home) after it turns on and we are holding the keys the capacitive keys leds start flashing like crazy and the phone doesn't turn on again after a while.
Any one knows what we can do to factory reset this phone?
sorry, just noticed there is a different forum for the t-mobile version
So you did try recovery mode, but it did not work? That's strange! When phone is turned off, press Volume up + Power + Home button and hold them until you see recovery screen (Android bot on cyan background). Then recovery menu will pop up (sometimes it can take a while for it to be shown). From there do the factory reset and wipe cache. But it seems you already tried it...

actually after posting this I noticed recovery mode was working but the display turns off while in recovery mode, I had to press the keys necessary for factory reset with a blank screen it worked and I got it to factory reset but recovery mode stills show and empty (off) display
Weird as hell =P

Samsung galaxy s3 GT-i9300 cant access the recovery mode nor the factory reset mode.

My samsung galaxy cant access the recovery nor the factory reset mode. I just replaced the screen and i need to reset it since i forgot the password i was using way months back. i tried the combo keys. volume up+home key plus power key. It just reboots normally. i try to make an emergency call and the volume keys are all working.
Is home button works? On my s3 it's hard to press correctly home button. When i want to go into recovery i press it as much as i can. Mostly I go into recovery with reboot options but when my phone is in bootloop I must go into recovery with combo

Gsmart Guru G1 forgot pattern to unlock. (can't factory reset)

Hello, There is a problem with gsmart guru g1. It is locked with pattern, and I can't remember it. (I didn't use it for long time).
To make things more clear I will list what I tried and what works, don't work:
-Can't turn on internet (Wi-FI or mobile) to sign up to google account when pattern is not correct after few attempts.. (Notification bar won't move... Tried it during a call, and so on..)
-Can enter factory mode (Volume Down), but it is chinese type (english language). There is no factory reset, or data wipe... NOT EVEN eMMC.... I think this factory mode is for testing purposes....
-Can't enter fastboot, or download mode... (that's a problem here, because If I could enter it, I would easily use cmd fastboot and wipe it from there.... (Tried button combos with Volume up, Volume up + Down, Volume up + Home and so on...)
-USB debugging mode is OFF... (Of course can't turn it on....(because it's locked...))
-Power button doesn't work. (but it is not a problem here, I just stick usb charger and do combo with buttons to enter factory mode.)
So this is interesting problem here... Because on other phones I could easily flash recoveries or change rom's... and so on... But this phone doesn't have normal stock recovery... I saw people on other chinese phones just choose eMMC in factory mode, but this option isn't there at all....
I really appreciate any help...
Any help ? :[
