Hi Guys, i've got a very big problem with my LG OB i want to install new firmware so I click on my dialer 3845#*970# and do factory reset, when my phone reboot i've got a password, when im on lockscreen and i slide up to unlock my phone says me "Enter password to unlock" but I didn't set any password and i don't know it. I install new firmware by KDZ but after reboot there is still password. Please help me !!!! What I have to do to clear totaly my phone, because now I can't unlock it !!!! Thanks a lot for help.
Try typing "0000" since it's the default for passwords.
No, it doesen't work. I've read that I can do factory reset but I don't know how if I can't go to the menu because I'm on lockscreen.
Any ideas ?
If i were you, i'd use the USB and Volume + to do a factory reset.

It is not FACTORY RESET ! It is just flash...
There's no other way to do a Factory Reset (wipe data partition) other than 3845#*970# or enter Recovery. But as we all already know, there's no key combination to boot directly into Recovery Mode.
BUT, if you have enabled USB Debugging. connect phone to PC and use ADB, and type: adb reboot recovery. This should help.
same issue
hi
i'm facing the same probelm , i forgot my password , and i dont what to do ,
this is the second week without having any sulotion,
please help
Hey, sry i#m new to this forum.
Have got a problem with my z1. After booting i am getting errors about com.android.phone crashed. Not sure but i think it began after a software update. Wanted to flash a new ftf and add a recovery but for all this i need usb debugging activated. trying to enter settings app failed when app crashed right after click to start. Without Settings or recovery no wipe cache or alternativ firmware? at the moment bootloader is locked, no recovery installed.
Tryed to hard reset (vol up and power button pressed for 15sec) but with no success .....
Any ideas?
Phone won't factory reset.
I have an m8 with stock rom and recovery and not rooted or unlocked bootloader. It wouldnt turn on last night and now when i turn it on it requires a password to decrypt the phone. It has a little note in the corner that says "chameleon" which is the passcode. But when i enter the pass it says right password but decryption unsuccessful with a reset button below the text and when i click it and it boots into stock recovery but won't reset and when i manually erase userdata or "/data" it fails and reboots into rom with the password prompt to decrypt again. Pls help

Can you boot into bootloader? If so, flash the recent RUU that is compatible with your carrier (Requires MicroSD card) and rename the file 0P6BIMG.zip and press volume up if you want to start update (This will factory reset your device, so i'm warning you now.) After update, everything should be starting normally again.
Hey Guys,
I unlocked my bootloader and installed TWRP in order to try to upgrade to Oreo.
After a while i decided to just stop with it and leave it stock.
I relocked the bootloader, but now it is hangs at 99% factory reset. Rebooting the phone just brings it back to factory reset.
How do i get in to Fastboot mode to unlock the bootloader again and see if it will just boot up?
Tried different key combo's but it only boots in to the factory reset procedure.....
1. Connect the usb cable already with the pc
2. Press and hold vol- and the power button
3. Connect the phone with the pc when the screen turns black
4. Still hold the buttons until you can see the fastboot screen

Thanks! But i already tried that. Does not work. Always goes to Factory Reset.
Will let the battery drain for now and see what it does then.
i think you flashed the oreo compatible twrp on your phone this makes your nougat phone stuck in boot loop. Try to flash the nougat compatible twrp or try the stock recovery.
I had a problem just like this.
All I did was wait for the battery to drain while it was on the reset screen, and on next bootup it didn't didn't go to that screen.

I can't flash anything that is the problem. Cannot get it into bootloader or fastboot mode or anything.

I let it die, and then i plug in the charger and it boots. I see the initial setup screen but it then reboots again and goes to the Factory Reset loop again.
Guess i will keep trying
Ok i got a bit further.
When i let it die, and then plug it in it boots to android. But as soon as i reboot it, it will go back in to the Factory Rset procedure.
Also adb reboot bootloader does not send it to bootloader so i can unlock the bootloader.
I also tried putting firmware (UPDATE.APP) on an external SD card, but it will not do anything with that either.
Anyone any other suggestion?? Need to either unlock the bootloader, or somehow flash original firmware/recovery.

No unfortunately not. When it is booted after draining it, i can do adb reboot bootloader but it just does not go to bootloader. Just reboots back in to factory reset loop.

i think you already need to send it to huawei service center since you cant boot to fastboot.
I really hoped there was something i could do since it does bootup after draining the battery.
Somehow the factory reset procedure should be stopped so that it boots up after a reboot. There must be some virtual switch to set or something. Problem is i only have adb to do something.
I managed to fix the issue with a tip from another thread.
After draining it again i let it boot again. Then i did a factory reset from the settings menu.
The phone then rebooted and did a lowlevel factory reset. That also was stuck on 99%.
I then rebooted the phone by long pressing the on/off button. The phone then restarted the lowlevel factory reset and that succeeded.
Now its working normally again

Hello, I don't understand how you arrived to the menu to select factory reset. For me even if draining battery, it continues to loop in factory reset and stuck 99%. . can you explain the procedure step by step. thank you !

If after draining it still does not boot normally then this does not work for you unfortunately.

try to use this service firmware it will update your phone into B364
- put the dload folder into the root of a fat32 formatted SD_Card
- shutdown the phone
- While pressing vol_up + vol_down press power_on button the upgrade will be lunched automatically
if the file does not work please provide us with the exact phone model to get the correct file

Ehhhhmmmm...... I solved this already
I wrote that in a post too......
where is the solution to this problem
I have the same problem, what did you do to solve it?
Hello,
After updating for the most recent update, my phone restarted and is now unresponsive showing: "You have to enter the password to access all functions after the phone is rebooted".
I cannot enter the code since the touchscreen is not working, it's completely frozen, although the animations seem to be working, since the clock is working and it opens the shutdown screen.
I tried a forced restart but the problem persists.
Any news on this problem?

Hey!
Thanks for the tip.
In recovery mode I still need to input the password and the touchscreen doesn't work.
Any other way I can input the password without the touchscreen?
