How to remove the Pin code from a locked Samsung Galaxy A3 - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

I have a Samsung Galaxy A3 that is managed by Airwatch. The device has got a profile installed that prevents factory reset (tried factory resetting via the recovery screen but no success). The passcode on the device is not known and the phone does not respond to commands from Airwatch so the phone is bricked. How can I get the passcode removed or factory reset the phone so I can use it?

Boot into recovery by holding down VOL DOWN BUTTON+HOME BUTTON+POWER BUTTON (I think that's the combo) and do a factory reset in your revovery? That might work

Then again, I'm not sure how AirWatch works or even what it is so I can't garuntee what I suggested will help

I dont really know what airwatch is, so i cannot gaurantee anything.
Here is what you can try-
Download the stock firmware for your device from sammobile.
Boot into download mode (vol down+power+home)
Connect your device to your pc.
Open odin, tick the pda/ap box and select your firmware .tar file.
Ensure only f.reset and auto reboot are checked. Flash it.
(ensure oem unlock is checked in settings)

[Q] Nexus 10 won't boot or fastboot after attempted unlock

I've unlocked/rooted/flashed many Android devices in the past, including many Nexus devices. I've run into some problems here and there, but I've always been able to get around them. This time seems to be different, so far anyway.
I started with the WugFresh Nexus Root Toolkit - I know how to do it manually but this just has everything included, the drivers, adb.exe, fastboot.exe, etc.
I told it to unlock the tablet, and it rebooted the device into Fastboot. The tablet asked me if I wanted to unlock it and I said yes. Then, NRT booted me into TWRP and gave me instructions to do a factory reset from TWRP (a step I've never had to do manually before). I tried to factory reset but TWRP told me it failed. Weird. Anyway, I decided to reboot the device from TWRP and see what happened.
All I see is the swirly, colourful "X" logo forever. It never boots into Android. I can reboot by holding down the power button, and I can get into fastboot by holding down the power button with Vol-. In Fastboot, I only have the "start" option (which works, but never gets past the "X"). I can't use the volume keys to select "recovery", etc.
From Fastboot, my computer does not show the tablet under "fastboot devices" in the command prompt. It does, however, show my (working) nexus 4 in fastboot devices.
So, without working android, I can't use ADB. Without fastboot connecting with fastboot.exe, I can't push through recovery. Without a working fastboot menu on the physical device, I can't try to go into whatever recovery is there or whatever.
And worst of all, at this stage I can't even turn my device off. It's just sitting here either in the fastboot menu or with the colourful "X". It's just sitting in its original box getting warm and using up its battery.
Any ideas? This is supposed to be a present for my wife for tomorrow - I don't really want to give it to her like this.
Just used wug's kit to root my second nexus device. Both times, it said failed during the factory reset. Wierd.
Put it in bootloader mode by pressing BOTH volume keys and power. There you should see the arrows and you can go to recovery but you shouldn't have a recovery installed yet. Instead, use the wugkit to download and flash a system image, hit the flash stock + unroot button. I also had to do that on both devices for some reason. After it flashes, your bootloader will remain unlocked and you will have a clean, bootable 4.2.2 rom. Then you can root from there.

Sorry I may have misread. If you are already in fastboot mode and your having a problem with your computer recognizing it, check your device manager for an uninstalled item, either adb something or android something. Then just follow the instructions in the toolkit to install the drivers. But try the flash and unroot button first and see what the toolkit says.
Same thing happened to me but luckily I had found this video before I started the unlock, root process.
Watch: https://www.youtube.com/watch?feature=player_embedded&v=T1Se7Hr9Cww
Seeing this guy missing getting the proper recovery menu really helped in understanding that it can be tricky.
I took the sage advise of others and did all the manual steps to unlock and root (no toolkit). The following link below is super whether your N10 is on Android 4.2.1 or 4.2.2 with instructions for Linux, OSx and Windows. Includes videos and pictures:

Hey mate, just wanted to say thanks. I don't know what is was that made the difference in the end, but your suggestion to use both Vol+ and Vol- together with power did the trick. I got it all working brilliantly now, thanks to you.
I'm still so confused. Why does Vol- and Power get into fastboot that doesn't work? I've never seen this behaviour on a Nexus device, or any Android device in general. It's wrapped up in a box ready to be given away in a few hours - but I will have a play with this fastboot because it's certainly weird. Definitely not like my Nexus 4 or 7.
Big thanks again. Hours of pulling my hair out and you saved me!
I believe the reason is the volume buttons are reversed. So when you think your pressing vol- your really doing vol+ lol.. That's what I did. Vol+ + power = download mode and it won't do anything from your computer. J think its an Odin mode.
Also for future reference you cannot unlock, and then use TWRP to do a factory reset. You will get a cache error. The only way it works the first time is to unlock, wipe through stock recovery, flash twrp and boot to success. But have to complete 1 boot before changing your ROM.
I've gone through multiple N10's and each of them had this behavior, I think its a bootloader bug since unlocking the device is supposed to perform a factory reset automatically.

S4 i9505 won´t remember wifi password SOLVED

hi, i´ve had this issue with my samsung galaxy GT-I9505, after i updated to lollipop I9505XXUHOE3, everytime i reset my phone i had to enter the password again, that happend in my home, my work, every single place, it just won´t remember any wifi network password, i spent several hours looking for a solution, even here i saw some post where they said some WIFI FIX NON-HLOS.bin file would fix the issue, obviously they didnt, at least not for me, also saw dissable the wifi power saving mode with *#0011#, didn´t work, so i used logic, and went to the basics when i first instaled a rom in my first phone, and i remember i read somewhere that had to be a clean instalation, so that is what i did.
1. Enter recovery mode (vol up + home + power)
2. on recovery mode, wipe data/factory reset, and also wipe cache partition.
3. power off
4. enter odin mode (vol down + home + power)
5. load the I9505XXUHOE3 file in odin on my pc and then flash it.
6. VOILA!!! now my phone remembers all wifi passwords that i enter.
if anyone has a doubt i will try to answer it withing my boundries of knowledge, that actually are very short, hope this thread help some people who hadn´t find the solution yet.!
What you have detailed is standard practice, and is what we all already do

An unauthorised attempt has been made to reset your device to factory default sett...

Hi,
I just bought a Samsung Galaxy J5 phone.
Upon opening the phone, i get the 'welcome' & language selection page.
I then get a message: 'An unauthorised attempt has been made to reset your device to factory default settings. Connect to a Wi-Fi or mobile network to verify your identity.' as well as Wi-Fi connection page.
I can't get pass this thing, and since the phone is completly new (not bought with a specific provider/contract either), i don't really know how it could verify my identity anyway.
I would be very thankful if someone has any idea on this issue.
Thank you!

At first, bad phone forum (It's J5, not S5). But I will try to help you. I recommend wiping your phone cache and dalvik.
1. Turn off the device
2. Click at the same time Volume UP, Home and Power buttons.
3. It will show you bootloader (should show)
4. Find "wipe cache/data" option
5. Click it
6. Click "Yes" button
7. After it's done, reboot your phone.
8. If it doesn't work, I have another option, but time-consuming.
2nd Option:
First you need to have:
- Samsung Odin
- Your phone ROM (To find on sammobile, needs to be in MD5 format)
- Good USB Cable (xd)
*Additional: download TWRP Odin flashable file (to download from the official TWRP file), much more comfortable than original bootloader. Make sure you picked up version for your phone and it's at least version 3.0.0.0!
Now the steps:
1. Turn off the device
2. Click Volume- , Home and Power buttons at once
3. You will see a warning information, just click Vol+ button
4. You should see: Download mode, do not turn off the target. In the right upper corner you should see "Odin Mode"
5. Now open Odin.
6. Make sure in "Options" you have "Auto Reboot" and "F. Reset Time" confirmed.
7. Now select PDA (maybe AP) and select your TWRP file.
8. When it ended loading the file, connect your phone.
9. You should see "Added!" in Log fold.
10. Now just click the "Start" button.
11. If it failed, remove battery from the phone for 5-10 minutes.
*Remove the cable too
12. Turn your phone into Download Mode again and start the flashing in Odin. (Check you have in "Log" "Added!")
13. If it failed, just try again after removing and adding the phone (worked for me)
14. When it's ended, you should see: All threads completed (succeed 1 / failed 0)
15. Now be happy of your working phone!

Solved:An unauthorised attempt has been made to reset your device to factory default
I have a samsung tab s3 and i to had the same problem. I had tried everything , changing the firmware of all available for the s3, factory resetting it, going into wifi advance setting changing the ip address. The DNS OF Xfinity the internet connection i use. To every so called solution on You Tube. To no success Untill I had an idea about not being able to sign on to Xfinity do to having to sign in after your connected to their network. So my AP couldnt connect to the internet ,could only connect to network. So i thought if i could connect directly to the internet AP will connect bringing you to the next page . SO what i did was go to a automatic connection like the one i used at Mcdonalds , Starbucks same thing. Any network that auto connects to the internet would do. Which will allow you to finish opening your tablet or phone. Everthing works fine on mine. As a matter of fact im using it as i write.
SOLUTION TO Unauthorized Factory Reset can't sign in wifi in
I had the same problem on my metro pcs J3 after soooooo much time trying to figure it out and even getting another phone , I went to a metro pcs/TMobile store and ALL IT TOOK WAS LOGGING IN TO THE WIFI THERE AND JUST LIKE THAT I COULD SET MY PHONE UP just try it you'll see

Rooted phone stuck on encryption

Hi all need help. I started encryption on my rooted S80 and read later that I needed to remove root beforehand. Now it is stuck in the encryption padlock for a few hours. I tried restarting and couldn't get out of this mode and cannot enter recovery. Any advise?
Also stuck

I am in the same boat. Any luck fixing this?
Hi guys, I stumbled on this thread on Friday 12-01-2018 cos I ran into the exact same problem. I was shocked no one responded with a solution. Well after scrambling with trials and guesses, I found one that worked. if you haven't already solved this problem, the simplest solution is to do the following:
Please note: This works for already rooted devices running TWRP recovery
1. Allow the phone to run out of charge while stuck on the encryption screen
2. Plug the phone to charge up without pressing the power button
3. Unplug the power cord and press Vol up+ bixby + power button at together to boot into recovery mode
4. Press Backup (yes you can still backup your data to external SD)
5. After backup, go back to the main TWRP menu and press WIPE
6. Press FORMAT DATA
7. Reboot the phone (you'll receive a warning that No OS Installed... this is good cos it means you've successfully formatted the phone)
8. On rebooting, the phone is just stuck on the Samsung Galaxy Logo (powered by Android) - this means you have successfully formatted the phone
9. Remove your external SD, connect it to your PC and copy your firmware into it, then re-insert it into your phone
10. Reboot to recovery using Step 3 above
10. Reinstall your firmware, allow your phone to boot up completely. This will take a while as it is a fresh install
11. Reboot into recovery and restore your data.
Hope this helps. It worked for me.

Not yet sure!
Hi All,
thanks to all for this question and the answer...
Please clarify me to get sure:
I've S8 with Oero (Stuck ROM) --> rooted (TWRP + Magisk)
Is it possible to set on the encryption?
If not, is there any other way/ROM/TWRPs to makes it possible?
Cheers,

Hi,
yes it is possible, i did it long times ago so i don't remember exactly (stock + encryption + twrp + root with magisk) but what you need to do is to set the encryption first and then root or you'll be stuck on encryption if you'r root first
What now?

Hey capsycum,
Thanks for the answer.
Well I did have the enc on before root, but as I knew some issues with OnePlus Phone I deactivated the enc before rooting.
Now the Phone is rooted - without having the enc on before.
So the question is if there is any way to activate the encryption - posthumously?
Cheers,
?
...anyone an idea?
?
Hey Guys,
I'd very appreciate, if anyone could clear the situation - or better - suggest a solution?!
Thanks

It is not true... I've tried any possibility...
Even the way to:
1. set on Enc.
2. Install TWRP, then directly to Recovery, install no-verity and then install Magisk
3. back to Download-Mode and install the self extracted stock recovery (from org. stock image)...
Did not help... (After first pass-phrase request of booting, it gives back the integrity error and never asks for pass again)
So... Any help is welcome!

Airwatch, MDM, g950u,

Guys, I Just got the phone today, used to have retail mode, MDM, those are downloadable, but today, the MDM locked so hard,
can't even get into the download mode and recovery mode by the combo buttons,
this bootloader was boot from
1. (this is Verizon phone) so can able to do another factory reset by press the power key+ vol down key, it was long wait, longer than normal s8 in verizon,
2. I choose factory reset, then the phone didn't do the resetting instead send me to the recovery mode, so I knew the MDM will block the factory reset in here,
so I chose the boot to bootloader instead, try to flash the combination, then this pop up and stopped. so crazy.

Guys, any suggestions?
