[Completed] Sony XPERIA Z1, SCREEN lock issue

Ok, so here is the problem.
I forgot the PIN number for screen unlocking on my phone. So 1st thing i tried is to reset the code via Android Device Manager, but Google tells me that there is no need to reset the screen unlock password because it already exists , and it does not allow me to reset my password although i am in my account and i entered my email and password :silly:
Anyway, next thing i tried is to do something via Sony PC Companion, but the app does not register the phone because i can't unlock its screen(which is the essential problem). Next thing i tried is to enter the Guest account and try something that way. And i didn't success anything that way. Sony PC companion recognized the phone while its in Guest mode, but it does not allow me to do anything backup reset update, nothing, it asks for an Owner profile. I can use the file manager, but it only shows me files on the phone memory as shortcuts i can't access them or copy them.
I really ran out of ideas, and i searched a lot online and no success so i figured XDA must have some kind of solution for my headache, or i am doomed...
p.s i think the problem may be in the OS, because on KItKat something like this wouldnt happen but on Lolipop it does ...

Device locked down.! I am done.!

Hi there,
I am happily using my Mi4i since more than a year now. Now I moved on to a new device and given my Mi4i to wife. Before giving it I did factory reset and internal storage wipe using 'recovery' (stupid me, should have done from settings). Phone booted up, everything was fine. But when ever I turned on Wifi (when ever the phone got connected to internet) it showed a screen says 'Activate this device'. What is the big deal, I entered my password clicked Activate. Well that gave me a mini heart attack. It said invalid activation code.! Then I noticed carefully and sadly figured out that the Mi account number showing in the activation message screen is different than my actual account number. Don't know how this happened How can I get over this ? or atleast know which email ID is associated to the showing Account (it shows account number with **** in the middle).? will a complete image flash fix this issue ? any help will be appreciated.
Note : Obviously you guys can think like I am a thief and it is a stolen device. If there is any proof needed I can post the original invoice here

Just try flash again with latest ROM via fastboot

Flashboot should resolve your issues, and now since you are flashing it as a secondary device, it may be worth upgrading it to Android 6.0.1 :

[Completed] Problem with HP Pro Slate 12

Hello
I have a problem with this tablet. It was used several people in my company. Someone tried to do a recovery but now, there's a message "this device was reset. To continue, sign in with a google account that was previously synced on this device". Nobody remember the account used.
I asked HP and they want me to pay nearly 400€ for that !!!
I think the USB debugging is OFF.
I can access the recovery mode by pressing POWER + VOLUME UP.
Options :
- reboot system now
- apply update from ADB
- wipe data/factory reset
- wipe cache partition
- apply update from sdcard
I tried wipe data and wipe cache partition, but same problem.
Can anyone help me ?
Thank you

Hi !
Unfortunately it looks like the tablet has been locked by Google via the google account after a factory reset , account which has been set-up previously
I don`t think you have any option considering that the usb debugging has been not enabled so you can`t use any adb commands if there were any workarounds available
The recovery commands you have there doesn`t help on this matter
Basically the manufacturer is the one who can help you out
You can search on Google or youtube , the issue is called FRP bypass
Good luck !

[Completed] Can`t open any app phone resets on every action

Hi all, i have an iNew V7 clone with 4.4.2 installed (rooted). A few days ago the phone started to lag and yesterday started to reset when i enter any app or settings. Can`t connect to it because i left it on charge only on USB options (resets when i try to change it), i have droidoverwifi which also doesn`t help (resets). Can`t do a factory reset, because it resets. I want to connect to it somehow, copy my pictures (not on the SD card) and do a factory default reset. Tried to change the usb options over adb, says null device not found . Any help is much appreciated.
TYVM

Hi !
Unfortunately there is no development support for this clone device here on xda
You can keep on posting here , users with a similar device may be around

Unable to reset S6 - Says abnormal factory reset

Hi all
I've recently reset my wife's phone so my son can use it.
However, after factory reset (using the buttons) when it reboots I cannot set it up.
It says that an "Abnormal factory reset" has been performed and asks for my wife's Samsung email/password.
When we put this in - it's rejected (actually, it says signing in but nothing happens).
We've reset the password but it still won't work.
I'd be happy to just format it an put a clean custom ROM on it but I don't know how.
All guides I find say it needs to be rooted first and to enable USB developer options - but I cannot unlock the phone to get to this stage.
Could someone please help me figure it out? Samsung can't (they want us to send it to them for a chargeable repair!)
Thanks
Matt

Hi, you don't need to root before flashing.
Samsung is AWESOME FOR THIS.
You can flash at any desperate moment.
It is time to install Android 10 for the dummies : https://forum.xda-developers.com/galaxy-s6/general/guide-tutorial-howto-samsung-galaxy-s6-t4108425

Thanks. I managed to fix it though.
I had to get the L2 Samsung account support to disable two-factor authentication.
Then the password worked and the phone unlocked.
The "this phone is blocked" screen requires your Samsung password but isn't smart enough to work with two factor auth (which is default turned on for all Samsung accounts). #facepalm

Nope the twofacauth is not turned on by default for Sam acc or any other acc on this Planet...that must be activate and config by user.
But if you have the right knowledge you could flash other Rom even if the Phone is lock by google. You just need to know how to.
