[Q] Regarding Factory Reset

Well Hello there, my name is poszy and i am having a very difficult experience.
So about a week ago i rooted my Acer A100 because i wanted cynogenmod, (i was running stock ICS)Long story short i bricked my tablet because CWM froze while i was wiping my tablet.
i did all of the following
1.) Rooted Tablet
2.) unlocked bootloader
3.) installed clockwork
All of these steps were done with the methods found here, Maybe it bricked because i was on Stock.
Anyways, i was lucky enough that my tablet only bricked to the point where it only looped during the android logo.
I am able to access the bootloader, but as soon as i tried to go back to ICS stock (because that was the only rom i could go back to and try to bring my tab back to life) that locked the bootloader. so now i have the stock bootloader. Everytime i try and flash a stock ICS update.zip it does not go past the android logo.
So i tried to flash the Honeycomb stock Acer_A100_1.014.08_COM_GEN1 Via stock recovery, and it all flashes well but for some reason it keeps asking me for a password.
i obtained the Acer_A100_1.014.08_COM_GEN1 from this thread http://forum.xda-developers.com/showthread.php?t=1307046
Stock Recovery seems to be working fine because when i power on my tab it loads into honeycomb but i cant get past the first screen because it keeps asking me for a password. :crying:
i have tried to do a hard reset with the pinhole but that does not do anything. Every Honeycomb stock rom i try to recover from always tells me to enter a password and every ICS rom i try to flash with the default recovery will not boot past the android logo.
on honeycomb i cannot do anything, i cant mount storage or access app drawer or anything because the pinlock dosent allow me to.
Can someone please help me and tell me what im doing wrong?
i was fortunate enough to make a nandroid of my ICS stock rom, but thats no use with a stock recovery right?

Since you flashed a stock rom, you should have a stock recovery, locked bootloader and unrooted. So you should be good to go, to just do a normal factory reset. To get rid of the pin lock.
-----------------------------
-Press and hold the Volume up button. Which is located farthest from the corner.
-While still holding the Volume up button, press and hold the Power button for 3 seconds and then immediately release it. Continue holding the Volume up button.
-The tablet will vibrate in approximately 1-2 seconds after you release the power button, once you feel or hear this vibration, slide the screen lock switch on and off repeatedly while continuing to hold the Volume up button.
-As soon as the Erasing Userdata... message appears in the upper left corner of the screen, release the Volume up button and stop sliding the screen lock switch. You should then also see the Erasing Cache... message below that as proof that your device is being wiped.

Many thanks

[Q] Won't start after rooting with odin

I try to root my S3 with odin now the only thing i got when i turn it on it's a few second of Samsung image and after that it's vibrating and nothing more.
I try to reboot it with the volume button down or up and nothing too
PLz help it'a a S3 from Rogers(canada) SGH-I747M

To reboot in download mode you need to press all together : Volume down, home button and power. In clockwork mode you nee to press : Volume UP, Home button and power and them let go all when you see Samsung galaxy S3 logo with litte blue writing on left top corner.

Are you booting into recovery mode correctly ? Hold home and volume up and then hold power until it flashes...then let go

Yes the only thing happen i saw tje samsung logo for 2 secondes and the phone vibrate and the screen turn black

Since I'll assuming you flashed rooted firmware, you need to access recovery to wipe data/factory reset and wipe cache in order to proceed. Which root method did you use?
Recovery mode: Vol up + home + power. When your device vibrates, release only the power button

And if it doesn't work you can force it into downoad mode by holding down the power. volume down and power key without the battery and then putting in a micro usb cord plugged into the computer. Then put in the battery. Thats the hard way haha
Or get into recovery and clear all cache and factory reset.

Which Odin did you use?
I've been using the one from this thread: http://forum.xda-developers.com/showthread.php?t=1822308 and never had issues.
Gotta make sure you download the one for Rogers.

So you successfully got it into download mode and flashed the stock rooted rom with no issues?
If so then you need to wipe data from and cache in order to eliminate the bootloop.
Again, recovery is: Vol up + home + power. When your device vibrates, release only the power button

How to boot into stock recovery

I'm trying to clear my caches because my battery is doing some funny stuff every since I got the tablet. Just constantly being used up, even over night it drops 25% when I'm not doing anything. I've only downloaded a few apps but it says "Android OS" is what's taking 50% of the battery.
So I get into Recovery by turning off the device, holding power + Vol. down and then I select Recovery mode.
But all I get is an image of the Android with it's belly open and it says "No command."
How do I get to where I can run everything?
Please help!
Thanks!

Is your bootloader unlocked and have you rooted the device yet? The only way I know how to clear the caches through recovery is by doing that first and installing a custom recovery like twrp. If you aren't rooted yet and don't want to root the device I would suggest doing a factory reset first and see if that helps. To do a factory reset go to settings --> backup & reset.

You can do a factory reset like the previous poster mentioned.
If you want to get the stock recovery menu from the android fallen screen, press volUp.

Here is your answer if you cannot get in to the os. The commands will not show up unless you do a two button combo. You can get in to stock recovery by doing the following.
When powered off
Hold power+vol down
When bootloader screen comes up
Use volume down to select recovery and then hit the power button
It will then go in to recovery but only show an android with exclamation point.
From here to see command you have to press power + the middle of the volume button (There is a middle button here) Saw the button in the teardown.
From here you can do a factory reset of the device also.

Yeah this didn't work. I know I got into recovery once without being rooted, but that was on a different device.
I did a factory reset so we'll see if that helps. But it isn't looking like it....
No apps downloaded, only on wifi, brightness is all the way down, turned off location services and the "Android OS" is still taking the battery. It's at 96% after an hour and a half of literally not using it at all...

When you get to the screen with the android and !, press and hold the power button and then press the vol up. No other combination will work. You can not press the buttons at the same time.

Boot Loop

Ok I feel stupid. I have been this stuff for a while but I just got a new in box Note 4 to play with and trying to root. CID is 15 and it came with 6.0.1 and I just Odin to 5.1.1 and it just boot loops. I tried running the Odin several times and same thing.
I flashed this file 5.1.1 N910VVRU2BPA1_N910VVZW2BPA1_N910VVRU2BPA1_HOME.tar
What am I missing here?

Not alot of help in this Note 4 area... You all are to quiet. LOL It seems like the rooting community is going away. I myself will not own a phone that is not rooted. Running the Moto X Pre as my daily driver and it's an awesome phone.
So I will post what I did to fix this Boot Loop Issue after trying to downgrade firmware to 5.1.1 from 6.0.1. I picked up the Note 4 from a local sell new in box for 100 bucks I figured what the hell kool phone to play with.
Ok I just flashed this official verizon 5.1.1 firmware N910VVRU2BPA1_N910VVZW2BPA1_N910VVRU2BPA1_HOME.tar with Odin 3.12 again
So After I got done flashing this firmware I did these steps.
1. Turn phone off completely.
2. To start the phone, press the following keys simultaneously: Power Button, Home Button, Volume +
3. When the first logo can be seen on the screen, release the power button, but hold the Home button and the Volume + button pressed
4. It now appears on the screen of your phone, a small menu. Navigate with the Volume + and Volume - keys. An entry is selected by the Power Button
5. Select in this menu now "Wipe Cache Partition".
6. After you have selected the entry the Wipe cache is flushed. This takes a few seconds. Then it automatically returns to the small menu.
7. Now select the top entry with "Reboot Now"
Also while I was in that menu area I went ahead and did a factory reset wipe all data.
My Verizon Note 4 is now on 5.1.1 and works.
Now I will continue to root this thing.

so the bootloop was caused by ? im gonna guess dmverity but it could also just been misflashed ....failing to uncheck the reboot upon flash option for example . powering the phone all the way down then into recovery ....id like to go with misflash if you had failed dmverity you would have seen a red message in recovery stating that was the case

Boot Loop help or can I pay someone to fix?
So my wife's Note 4, not rooted. Must have failed during a forced update. It's gone into 2 types of boot loops. Either it says 'Recovery boot' only, with no recovery menu, followed by the 'Galaxy' screen, and then back to the boot loop. Or it shows the Galaxy screen, and just barely begins to initialize the 'Samsung' logo with the 'S' first, and then back to boot loop.
I've tried about 3 different firmwares through Odin, including successful ones that 'Pass'. And it still exhibits the same loops. I've tried bootloaders in Odin, about anything you can imagine. It's clearly not bricked, but I cannot for the life of me make progress.
The old battery I thought was going bad (a lot of bad battery problems with loops), and I bought a new battery. But given it will only loop (outside of the download screen), I can't even get the batteries to charge because it's either looping or on download screen.
Any questions or ideas? Or is there a user who is an expert I can ship and pay to fix?
I'm a novice in large part. Thanks guys.

Hi when in odin ensure you untick reboot after flash . Power it all the way off upon sucessful flash then power it back on into recovery (hold up volume power home) wipe cache wipe dalvik reboot system. The power off is absolutely crucial and the most common flash error. If this doesnt work repost shouldnt be too hard to fix things is damn near unbrickable

If you change from 6.0 to old 5.1.1 firmware with Odin it will go into bootloop. You must do factory reset, than use Odin to flash 5.1.1 and than do another factory reset.

any way to uninstall wrong AOD update on not rooted g9600 (oreo, half bricked)

Here what i did: found a newest version of "allways on display" from apkmirror and installed on my oreo g9600 phone. It boots, but only black screen and apps edge. But nothing starts from edge. Only power button work, it brings 3 option that dont work. Hard restart works, can boot to stock recovery.
The big question is it possible some how restore system without factory reset (or flashing rom)?

boot into safe mode and see if you can go uninstall the app
Press and hold the Power button again to turn on your cell phone. Immediately press and hold both the Volume Up and Volume Down buttons on your device. Keep holding while the device boots. Once your Android device has booted, you will see the words “Safe mode” displayed at the bottom-left corner of your screen
