locked lg g2 - G2 Q&A, Help & Troubleshooting

Hi. I had a pin unlock for my phone. I forgot it and entered it too many times. Now it wants me to unlock via my google account which is totally fine...but my phone wasn't connected to WiFi or mobile data wasn't enabled.
So even though I enter the correct details the phone cannot verify them!
I went unto Android device manager and tried to reset the lock screen but it failed to work.
I don't want to do a factory reset as I have not got some recent (and really quite important!) photos backed up! What do I do?
I tried to use a USB cord connected to my phone and PC but because the phone is locked only sleep and charge works.
Please help! Gracias

After you failed numerous times, doesn't the phone give you the option to log in your google account and reset the passcode?
If you haven;t log into your google account in the phone (you go to play.google.com, and use the Android device manager to change your passcode, or enter the code wrong many times and it will let you have an option to reset by your gmail).
Or if you don't have adb debugging enable or someway to access it, there is no way except factory reseting.
How in earth you forget your code and can't log into the google account?
You aren't using someone elses phone are u?

Install adb, connect your phone to your PC, then use the command "adb devices". If a device code is listed, then it's enabled.

[Q] locked out from device, not accepting Google Id...

After following a process elsewhere on XDA to set up a pin lock, (here: http://forum.xda-developers.com/showthread.php?t=1848962&highlight=lock) I've been locked out of my device, with the response Too Many Pattern Attempts.
It says: "to unlock, sign in with your Google account." But I do that, and receive an invalid login response. (This is without active wi-fi, which I can't access for the settings!) I'm not certain that it's trying to connect online, but that's my only explanation for why my google credentials aren't working.
I was hoping I could use ADB to reset the PIN again, but ADB doesn't appear to recognize the Nook; maybe it's not opening up the device to USB until it gets unlocked. And ADB Wireless is something I can't even access until I get past this!
I'm currently on the road so I can't go back to my home wi-fi... and I'm not even sure that the nook would connect to the home wi-fi anyway.
At the very least, I'd love to find out how to boot it in recovery mode, maybe re-install and re-root everything. I've seen a few posts online about rebooting in recovery mode, but nothing consistent.
Any suggestions?

[Q] HELP! My phone is locked with Android Device Manager and I can't unlock it!

Call me stupid, but I'm really desperate and begging for help! I used the Android Device Manager on my Tab 3 8.0 to remotely lock my phone. So it worked. But when I used the password to unlock the phone that was set earlier on ADM, my phone keeps saying that it is the wrong password.
Fair enough, I actually used my home PC to do the exact same thing. I went to the ADM site and set alphanumeric and numerals only password and still, WRONG PASSWORD!
What can I do?! I restart the phone and then nothing worked!
Hello siva992, put it back into the two new password in the computer I use only four digits, not failed. Remember to use new numbers, not the same as you have before. Good luck.
You should contact them for help as if it's not notes fail.
If no other ways then you have to do a reflash with Odin.

i too had locked my nubia device through android device manager.
it can be bypassed by rebooting into recovery mode and you need to format /data and /cache.
after this restart your phone through recovery mode it may take 5 to 10 minutes to finally show "android is updating your apps " something like this.
this method worked on my nubia mini and i thing technically it might work on every android phone that is capable of booting into recovery mode.
this method would not delete your photos,music,etc.
only contacts and app data will be gone,i am sure that won't be an issue.

Lg G2 cant go to download or recovery mode, phone works fine but i forgot pin code.

I have been using knock code but later when i took my phone from my pocket it showed pin code. I forgot my pin code, I know my email adress and password but wifi and cellular data is off in the phone.
I bought this phone as used. I wasn`t able to connect my phone to pc after i bought. I get device not recognized error in windows. I also had slow charging when plugged with its charger though it charged in 2 hours.
1. Telephone works opens fine, but asks for pin code or email, i know email but cellular data and wifi is off in phone and i cant open wifi or cellular data.
2. I tried to do hard reset but i cant go to recovery or download mode, tried volume up for download mode, tried volume-down power and volume down-up simultaneously or volume-down power and volume down power again for recovery,. no luck.
3. I am stuck at pin code and email menu, i can use camera or quickmemo, i tried to open every app on quickmemo but couldnt open wifi or cellular data.
4. I use 4.4.2 kitkat lg g2 d802 , installed every driver, tried on other devices, other os`s. Cant get the phone recognized by pc.
Any suggestions ? I am really frustrated. I just bought it 1 month ago. Trying to find its pin code hopefully for 2 hours and no luck :crying:.
Anyone really any suggestions? i am open to any opinions. I can try anything to make this phone work...
Can motherboard be damaged ? I have never had any problem while gaming or surfing on net while using the telephone though. Why do you think that I get code 43 Not recognized device while i try to plug in and connect to my device and also i can't get to recovery or download mode .
You're just saying "Pin". Is it just a SIM-lock or is your phone encrypted? In first case try another sim. In second case please take a look at this fix-list:
https://forum.xda-developers.com/showpost.php?p=63327417&postcount=4
It is not about the pin code of sim card. It is the password of telephone after you put screen lock to your telephone it asks for pin code in case you forgot your screen lock combination.
And there is no such thing applies to my problem in fix-list. I assume that my motherboard or charge socket is damaged so i cant connect my telephone to pc. And also i can't go to recovery mode or download mode but telephone is working fine though asks for pin code password or email address.
and no, im not just saying "Pin"
is there any fix because i am having this problem too ?
Update:
I can go into recovery mode, i was able to do it after trying 10-15 times.
In recovery mode, after i start hard reset, i get boot certification error.
i wasn't able to get into download mode, Computer can't recognize the telephone. i think it's because my usb port is damaged.
i tried to connect adb while in recovery mode but computer didn't even found that a telephone is connected.
i have done some research and do you think i can flash rom using JTAG ?
do you think if i buy 8$ lg g2 d802 charging port flex cable , would i be able to get into download mode and computer would recognize the telephone ?

No Password entry possible after unlocking bootloader

Hello dear communtiy,
i think i have a quite serious problem: I unlocked the bootloader on my Huawei p8 lite 2017, and it started an obligatory factory reset (because of possible data theft...). Well, after rebooting i find myself without a keyboard to enter my password. I normally use the fingerprint sensor to unlock it, but when you restart it you have to enter a password. There is a numpad for entering the PIN after restart, but just no way of entering anything into the password box. Its a text password with 13 letters (if thats any important). Of course i searched for solutions on the internet and tried almost all of them:
Idea 1: Boot into safe mode: No keyboard in safe mode
Idea 2: Use Huawei erecovery: No keyboard after whats effectively another factory reset (at least thats what i think it is)
Idea 3: Use Google Play on the PC to remotely install a keyboard: Google Play now says a keyboard app is installed, but theres still no keyboard on the phone
Idea 4: Use ADB to somehow do something: USB debugging IS enabled, but my phone is stuck at using USB only to charge
Idea 5: Use a USB keayboard with a micro usb adapter: havent tried that yet, but i am not sure if it will even allow me to enter anything via USB before the phone is unlocked
Idea 6: I have made a Backup of Apps and such via Huawei HiSuite before unlocking the bootloader, but i cant figure out a way to apply it. Maybe it will bring back some form of keyboard when applied.
Im currently doing another Huawei erecovery just because i hope it will do something, but i dont think it will. I am in desperate need of my phone and beg for immediate help. I didnt flash anything onto it, i just unlocked the bootloader with this code you get. I am less than a beginner at screwing with phones. I feel really scared at the moment, since i only had this phone for a couple of weeks. Is there any hope for it?
Again, im begging for it to work,
Kalle
Edit: After in total 3 "resets" theres still personal data on the phone, because i see my old wallpaper on the locked screen.
