Locked phone after factory reset - Samsung Galaxy J2 Questions & Answers

Hello.
A few weeks ago my wife forgot her pin to unlock phone, there was no other choice than just reset phone to factory settings via stock recovery.
Eveything was nice until phone wanted me to log into the previous google account that was used before erasing everything. My wife dont remember password and login either. She created it while ago just to use the phone.
Ive got no warranty for it as I bought it used.
Is there anyway to bypass that security? Otherwise phone cant be used again.
Thank you.

Whoa, you taught me something new today :good:
It's kind of a shame it's specific to the J2 Prime phone, I wonder if there are other methods for other phones similar to this

There is a method of launching a shortcut to settings via an app installation from otg at time of setup. That works.

[Q] Can not unlock the Nexus 7 in Android Device Manager

Hello everyone,
I encountered a problem with the Android Device Manager. I want to test the ADM. I tried several passwords. But now I locked it, do not know which one is the true one. Actually I remember them, but no one is correct. I tried to update the password, it gave back a message like
Code:
Your new password was not strong enough. Your device has the following password requirements:
NaN - 16 characters long
even I have tried a password like dt8UZLhFknapYK7L.
Anyone can help me? Thank you.

Wouldn't it just be your google/gmail password? Try it from a computer. https://www.google.com/android/devicemanager Well, just noticed you do need to create a new device password. Bummer! If you can't get it to work factory reset.
Reboot your device and try again.

No, it is not the password. I have already tried it before. I tried all the password I remember.

I was just messing around because I've never tried locking any of my devices. I had to reboot to get the password to work.

That sucks! I think you probably just misremember your password. I know that my daughter's mother uses it often enough to lock my daughters phone and it must be working fine because I'm sure she would call me and be a pain in the a$$ if she had any problems!

No, I do not misremember it. You see what message google gave back to me? NaN - 16 charaters.... NaN is always means a bug. It is google's fault.
BTW, is your daughter's mother your wife?

****ed up my P8000

Hello XDA, this is my first post, this comunity is awesome and helped me a lot for a couple of years now.
there always seems to be a solution to everything!
but now i realy ****ed up. i accidentaly checked the wrong thing on the so called "smart phone flash tool"
i klicked firmware upgrade instead of download only.
is there any way so rescue my phone? thank you very much in advance! :crying:
here is a screenshot: (i cant paste link because i am new):crying:
I'd better let someone more qualified answer your query but I'm pretty sure your situation can be recovered easily. What happens if you try to reflash the firmware again with the correct settings? These phones are pretty hard to brick!

there probably is SOME way to fix it, i am sure, but the phone does not even boot into recovery.
Mediatek phones are hard to brick, haha
It is PROBABLY going to give a headache in order to find the needed files, flash the stuff again and etc using the proper way, but PROBABLY your phone will relive again. Try rooting and installing Eragon after a full wipe, if that option is available.
You may look here:

This may help.

Performing a full data format with a custom recovery multiple times will leave no personal information. Then you can go do your restore to stock ROM

Is this your first phone? First android phone? I mean a quick google search would of told you how to reset as well. Also factory reset is just that a factory reset that puts your phone back to factory specs like when you first got it. Also better information in your post would of been to let us know if you were rooted or not and not your bad phone purchasing choice.... j/k not really LOL
Hope you got it all sorted out if not let us know we will be more than happy to send you off the right way :good:

Hi,
Did it work well before?
Did you do a full fw flashing before?
Have you tried to change the radio in *#*#4636#*#* yet?

No Full Flashing before or even now
I tried to change Radio, thanks for your trick, but it does not work!!!!
I still need your help
It's a weird problem. I think you should do a full fw flashing if you bought a 2nd phone. If it's a brand new one, I have no idea about this situation :"|

I can't help further unless you cooperate to troubleshoot. When you are able to factory reset to nuke any stuck bits and start fresh on a new Google account, (not a secondary one you already have, a brand new one) then we can try pulling a log from a fresh install to see what is blocking it.
Edit: the factory reset would need to be followed up with a fastboot -w command to ensure everything is wiped. If you don't want to do this, then you cannot be helped.

Did you buy it online?
Besides the model, what is your software channel and build number for your phone?
i had similar problem and factory reset still resulted with the same issue. I had to do a full retail rom reinstallation and that fixed the problem.

Yes, I bought it online from coolicool.com, this is first time ever I bought one Moto from outside of USA,
Software Channel: retcn
Build Number: OPXS27.109-52-10
Thanks for helping me
The model and build is exactly like mine when I first got it.
First off, I think it's how they flashed the rom that's causing the instability. Your phone would most likely have it's bootloader unlocked like mine but they did something to hide the warning message.
Please read my thread.
https://forum.xda-developers.com/z2-force/help/request-advice-experts-tourbleshooting-t3928349
You will see that I flashed a retail rom using instructions from this thread. It would be step E of the thread. Worked like a charm for me in fixing all the unstable apps
https://forum.xda-developers.com/z2-force/how-to/guides-bootloader-twrp-custom-roms-root-t3805737
You will have to flash your phone so you really have to follow the step by
step instructions.
I did it for the first time in my thread, it's not hard to do step E if you follow it step by step.
Hah, mine was from coolicool with random issues too. Emailed them, no response. Paypal claim, no respond. Full refund!
Will follow the guide above.
Just check first if bootloader is unlocked. (That's step a). Before you proceed to step E.
I'm assuming it's already unlocked because we have the same issues, build and model number. Mine was unlocked when I received mine. Also from China/hk

why it's unlocked?
it's not Original and it's not from Motorola?
I saw in bootloader it's flashing_unlocked and I was surprised why unlocked????
are you sure if I do these steps problem will solve and also are you sure after installing new stock ROM dual sim work well?

This is my pure speculation. the reason why its unlocked is because it was originally a chinese phone with chinese roms that doesnt have playstore. That must have been the original setting. Since they want to sell it to the international market, they had to unlock the phone and voiding the warranty, flash it with the new international rom before selling it.
Since its unlocked, essentially the warranty on your phone is void. The issue i found is that they must have flashed the wrong rom so its causing all these apps to crash.
Again thats all speculation and theory.
Now the only reason why I'm suggesting this method with you is because I had the same issue, I researched and tried the solution I posted. It worked for me. If you are going to flash a stock rom for the first time, you just do your research and do it one step at a time. Instructions have been provided in the second link (step E) including all the files you require to install the retail rom. It worked for me. I can only suggest, but it's up for you to give it a go.
I loaded the latest RETAIL (-05) factory image and all apps are functioning fine now. Issue was supplier had flashed -06 ROM, assuming because it said APAC in the description.
happy it worked

I was so confused during the last month. The random apps that were impacted by the issue didn't make sense...
Banking app
ABC Kids Listen App
Kids Daycare App
FuelCheck
Images on CyberFlix
Only one of the devs managed to get their app working for me in the odd state it was in. DayCare app of all things!
Thanks for posting, I wouldn't have thought to reflash or even look at the region code of the flashed rom compared to the compatible one.

Yeah it was so random, i really thought i got a faulty phone. Mine was all GPS/ internet related (Uber, Spotify, maps)
Nothing made sense but I took the research and decided to flash to stock rom, discovering they installed the wrong ROM and HIDING the fact the bootloader was unlocked. Definitely not your average issue and hopefully this would help other people who are in similar situation buying from any china/hk store.
I even bought the moto mods, and they are working perfectly after reflashing. Pretty happy with overall result.

Nexus 7 locked with FindMyDevice but not found on Google account

i have a Nexus 7 I have not used for some time and I was going to give it to a young grandson. When I started it it reported that the device was locked by FindMyDevice. Because I hadn't used it for some time it has been removed from my Google Account.
I have booted into Recovery and it goes into TWRP (it is unlocked) but when trying a factory reset (or any of the other options) from there it will not permit me to use the Slider within TWRP necessary to action the selected option.
Can anyone kindly advise on how I can factory reset it?
I don't know if this will help but it might be worth the try... or there might be something similar that might work for you.....
https://android.imyfone.com/remove-phone-lock/
Thanks for that . I investigated this and discovered it was designed for Samsung devices and not guaranteed to work with others. As it cost $30 to use it I decided to explore other wiping avenues but thanks for the info.
