Forgot KnockCode Lock on LS777, need help figuring out my options - General Questions and Answers

Hello, I recently found an LG Stylo 3 in one of my drawers that has a knock code on it. I don't remember the code and I already tried 66 times to unlock it (it now takes 240 seconds between each attempt). No "Forgot Password" or backup pin option shows up, USB Debugging is on but it's unauthorized, and the mode that it's on when I connect the phone to my PC is Charging Only. I just want to know what pictures I have saved on it, or if I can pull out my photos or something. I can't reboot into bootloader from the recovery options, it just reboots my phone. I'm able to go into recovery, and safemode, update from adb puts it into sideload mode, and it's connected to my wifi but because I changed my passwords on my google accounts already, the phone doesn't show up in any of my google device manager accounts.
Everything is stock, no custom recovery or firmware and it's not rooted.
What can I do now? Is there a way to reset my password or bypass it entirely? I don't care how technical it is, if given a good guide I can do it. I can't find anything to help me, hopefully someone can help my problem here.
Before anything, I didn't steal the phone, it's my old phone I had when on Virgin Mobile, I can give as much proof as I can to show that it is my phone if needed. I just don't remember the knock code
Thanks!

[Q] [Too many pattern tries] How can I switch on wi-fi?

Like many others, I have become a victim of 'Too many pattern tries' and have got stuck at the lock screen trying to sign in without data connection or wi-fi. Is there any way to get past this without data rewipe. It's really stupid of Google to have a security mechanism that forces you to wipe your data, meaning anyone can just pick up your phone and spam the pattern till it goes to the email screen (which is what happened in my case).
I have a rooted phone with an unlocked bootloader and USB debugging enabled and I also have downloaded Eclipse Android SDK but have no idea how to use it. It would be nice if someone gave me step-wise instructions on switching on my wi-fi through the SDK so that I can connect over the internet and log in.
Of course, any other legit method is also fine, but the 'home button method' doesn't work for my phone (you know, keep pressing the home button). I have tried getting APKs that will help me bypass the lock screen but they dont work.

Android Device Manager is not able to pinpoint the location of my phone. Do I need wi-fi for this? The only options I see right now for my phone are to change the name, give it a ring or lock or erase.
I have finally found a way. No root or USB debugging required.

[Q] Used wrong Lock-Pattern, now phone is locked. No method tried works for unlocking

Hey guys how's it going?
Story:
My little cousin borrowed her old HTC Desire S to a friend.
This said friend, might have changed the Google Account and activated a Lock screen-Pattern, although she claims "I didn't change anything".
She claims, her sister tried to access the Phone while she was in school but couldn't, because of the Pattern Lock, so it locked up.
My little Cousin had a similar problem before (she knew her pattern but somehow it didn't recognize it and locked it. I unlocked it with the Android Device manager, since it didn't work with her Google Account).
She hasn't put a new Lock screen-Security Pattern/PIN/Password since then.
What I did so far:
tried putting in the Google Account Information of my Cousin
tried it with the Android Device Manager, but it couldn't even find the phone
tried entering the Recovery to perform a factory reset, but it just boots up normally
tried gaining information on How-to re-flash stock firmware but all I've found, required you to get into "HBoot" for relevant Information (which I can't access somehow)
So, is there anything I can try to regain access to the Phone, I don't already have?
It would most likely be a back-up phone, so, if it's lost, it's nothing too bad but, I mean, it cost quite some back in the day...So yeah, would be cool if you guys have a solution!
Thank you in advance for reading this post and thinking about/providing a solution!

EDIT: I forgot to mention, that my PC doesn't even recognise the Phone properly. It finds a removable Drive but it says "Put in a storage Device in the removable drive(H)" and if I want to save disconnect the device, there is only ". . ." listed and it doesn't do anything. I assume it is in "Charge-Only mode" or something.
Oh and it's connected to my Wi-Fi but it wont install apps (through Play Store in my PC Browser), since I tried one of those "remove Lock-screen" apps.
Pull the battery out for 15 seconds then put back in then press and hold volume down + power button. That should get u into bootloader and there u can try factory reset or if all fails try a ruu.

[Q] How to access data from locked s6, no wifi, no debugging

Model: SM - G920W8 (Canadian)
I recently purchased an s6 (1 month) and used the fingerprint scanner to secure the device. I made a backup password and made sure it worked and all was well until one day when it all of a sudden stopped working. Normally I leave Wifi on and could solve this issue but as to save battery I had disabled it this time around, silly me. So the fingerprint scanner denied my entry, led me to the backup password which also failed (even though it was correct) and then Wifi was off so Google verification did not work.
Being a new phone, I did not get a chance to turn on USB debugging (this happened 1 week after purchase) so using ADB to turn on wifi was of no use, it did not recognize the device.
Here is what I have tried to do to recover the data up till now:
>I used ODIN to install TWRP on the device.
>With TWRP enabled I made a backup of the data and attempted to connect to adb once again, Using my sisters Galaxy S6 I tested out whether hers worked, just to make sure everything was fine with the drivers and to make sure adb devices recognized her phone: it did.
>I ran ADB devices while in TWRP and it recognized my device, but came back OFFLINE, meaning no commands were able to run.
>I then attempted to run a series of drivers and to access files directly from windows 7 and did not have access permissions to read nor write, thus unsuccessful.
>I went back to ODIN and sought out a stock rom to flash to the partition in order to get access to the backup data i had created using TWRP, as there seems to be methods to flash a rom and maintain the backup data.
> With ODIN i tried this, but was unsuccessful, as it got stuck on "Nand Write start" and would not initialize any transfer with the phone . ( The download mode would not start the progress bar)
>Finally i tried to do it with TWRP but because i have no write permissions, i cannot put anything onto the device for it to run.
I called Samsung about this and they know of the issue and refuse to help me other than a useless factory reset. They knowingly allow users to continue using their fingerprint option for security but do not give warning of its issue, nor do they provide a simple fix like allowing wifi to be turned on from the lock screen. It is a shame that a company like this just allows a known software bug to bother users but doesn't make them aware of it, nor provides a temporary fix while they work on fixing the issue.
I am stuck, and need your help, I have done everything I can think of but can't get anywhere, please help me retrieve my data. Thanks
Wifi is off but how about 4G/LTE data?
If your 4g lte data is working you can use findmymobile(samsung site) and unlock it from there. There's an option to unlock your phone. I came across this issue last month.

Yeah LTE is also off, otherwise google login would have worked.
I can access the WiFi toggle from the lockscreen without having unlocked the phone via FP - although I'm not locked out the phone so wondering if being locked out stops you gaining access to the notification drawer as well

Via FP? well I can indeed access the notification drawer (from the top, right?) but when i enable wifi it asks me to login using the fingerprint.

FP - Finger Print
i have the same problem what to do now i dont want to lose data and my s6 edge is not recognising my fingerprint rather asking for a backup password and i forgot the backup password so the wifi or mobile data is switched off and i cant even turn it on what to do now?????
I have the same problem...agree completely "They knowingly allow users to continue using their fingerprint option for security but do not give warning of its issue, nor do they provide a simple fix like allowing wifi to be turned on from the lock screen. It is a shame that a company like this just allows a known software bug to bother users but doesn't make them aware of it, nor provides a temporary fix while they work on fixing the issue."
factory reset is "the only way" to unlock it. Lazy samsung customer service response.
logging in via google is not an option on S6 / new android system anymore so if you forget your pin you're stuffed
this is really poor on samsung behalf to not give warning of the seriousness of using a fingerprint scanner
ha I can't remember (and can't check now) but does it even ask for the pin twice to verify what you entered what was intended?
google use to have a device pin reset but it was removed recently.
I bet heaps of people have this issue.
I am desperate for a solution...
I just registered to help future users having the same problem.
Guys I spent around 15 hours trying to unlock my samsung galaxy s6, and found a solution. You're wellcome because you need google acc+dont need a connection for this to work (worst case scenario).
It didnt recongnize my fingerprints, and my backup password didnt work. I couldnt sign in to my google account since my wifi and mobile data was turned off before the device locked.
This is the solution i found AFTER 15 hours of this madness, you need to be quick:
1) enter wrong backup password 5 times
2) wait 30 secounds countdown
3) enter wrong backup password 5 times
4) wait 30 secounds countdown
5) select sign in with google account
6) enter google account credentials (DONT SIGN IN YET)
7) hold 'wake up button' (home button)
8) press emergency mode and go thru with aggreeing to all it asks you to
9) press TURN ON, and after that press 'sign in' with your google account (where step 6 left off)
If you were quick enough, you will enter emergency mode and you will pass the lock screen, now quit the emergency mode the same way and change your backup password, and write it down this time so this doesnt happen again. You are wellcome.
Thank you, that happened on 4th try, "quick enough" is the key. It appears that it turns on WiFi and mobile data for fraction of a second during the process.
yeah i seen that for a fraction of seconds wifi turns on but how should i unlock i am not done please please help me i dont want to lose my imp data
THANK YOU!!!

Bypass setup — is it possible?

I returned my phone to stock UE40. So it's in something like a factory state. I booted up and, as expected, got the language selection screen. After that, I logged into my WiFi network. But I don't want to enter my account info. I just want to get to the home screen. Seems to me I did this very recently, but that may have been on a Nexus device, maybe one with a custom ROM. I don't recall for sure. Anyway, I can't get past that system request for my Google email address. Is there a way to do this where I can just get to the home screen without entering credentials?

One method is to NOT enter your wifi...or to tell it to forget it...maybe pull the sim to so no data connection...then it has no option to setup a gmail account and should let you skip it.
Once at home screen you can go into settings,wifi and re-enable your wifi.

I don't think I was able to get past the wifi request. That's what I tried the first time around. I could reset and try it again. The SIM card is already out.
I reset and tried to bypass the wifi selection. No go. Even if I turned wifi off, the system would just turn it back on and cycle me through language selection and wifi network. Strange. I KNOW I did this recently, but that may have been on a Nexus 6. Probably was.
FWIW, every time I reset the device, it bootloops when I try to boot into the system. Tonight, this happened a few times. First, when I wiped the device, flashed a system image, and tried to boot into it. Then, a few more times when I reset from stock recovery. Each time, I'd power the phone off during the bootloop and then restart. And it would be OK.
No matter. I'm where I need to be. Just wondered if there was a way around wifi selection and and entering an email address.
Sorry to bump this thread,
But I'm having a similar issue. I restored the phone and booted fine. Until I got to the setup page, I couldn't skip it so I login in my credentials and the "protect your phone" prompt appeared and sent me back to the language screen.
I’m restoring it again using the restore software 4.9.2 tool, since I had the 5 percent issue earlier and I’m going to try again and see if I can skip it.
Of course I’m unable to set up usb debugging as I can’t at least accessing the main home screen.
Any advice suggestions are much appreciated.
Thanks.
Never mind got it working and back on Twrp and flashing. Used an old samsung trick and accessed the developer settings that way.
How you did it?
I can tell you what I did to bypass it.
I first got a USB OTG flash drive from the local computer store. I then downloaded an unsigned apk file from any site that has them. Personally I stumbled upon this solution so I had some random "Unlock your phone" APK on the drive. Anyhow, when the phone was on I plugged the flash drive into the phone and tried to open the APK file, it gave me an error message stating that the app was unsigned but then it allowed me to go into security settings, from there I could turn off all of the google verification crap. After I turned off all of the settings, I wiped the cache on the phone, restored it, and it was fixed. No more verification screen.
i HAVE NO ISSUE ON 6045y WITH STOCK FIRMWARE OR WITH DCZ FIRMWARE. I can bypass the setup screen normally.

[Q]Is the Huawei H710VL bootloader-unlockable, even WITH the unlock code from Huawei?

Little bit of background first...
Finally got my parents (senior citizens) into the smartphone era after StraightTalk starting doing BYOP and I'd had good service so far, but rather than use his old HTC phone which badly needed replacing, he opted to buy the Huawei Sensa (H710VL) branded by TRACFONE and with service via StraightTalk. Fast forward several months, and the old man has discovered a deal for senior citizens from T-Mobile that he likes better, and has opted to switch carriers. Well, he tried to do BYOP with TMOUS and just continue using the H710VL which he likes, but was informed that they wouldn't unlock the phone for another month because they won't do so until you've had it for a year. So therein came my opportunity to promise something I apparently cannot deliver (I told him I'd take the phone home and unlock it for him)!) He (wisely) decided not to wait for me, and went ahead and bought a new phone from TMOUS so he could initiate his new service with them without delay. But I still want to unlock this phone for him, if at all possible!
Fast-forward a few more days--well, I've been screwing around with this phone in the evenings for the past three days, trying to get the bootloader unlocked, and I'm at an impasse. First I had to tangle with the Google account verification, which wouldn't let me even sign into the phone after boot and get to the home screen because I had done a hard reset of the phone first, and didn't have the old man's Google account and password with which to sign back in. Fortunately, intrepid folks who came before me already found a way around that first hurdle. I took the following steps:
1. Went thru HWStartupGuide process until I was able to connect to my home WiFi network. So, internet connection is established.
2. Backed out of there to get to the first setup screen after the TRACFONE splash screen on boot, and used the "emergency calls only" escape hatch to navigate to the stock dialer app.
3. In stock dialer app, entered (without the quotation marks) "*#*#6130#*#*" which took me to the SIM Card Settings screen. Tapped three-dot menu, tapped, "Add SIM Contact," which took me to the native Huawei Contacts app. In Contacts app for the SIM card, tapped "Add Contact," made dummy contact called "Test" with a ph# of 1234. From list of contacts, tapped the "message" bubble icon next to the new "Test" contact, which opened the stock Messages app.
4. In stock Messages app, typed and sent message with the text "www.youtube.com." For obvious reasons the message doesn't send, but it does appear in the messages window, which renders the draft text's content into a hyperlink to YouTube. Bingo! Tapped link and opened up the YouTube app.
5. From the YouTube app, tapped the three-dot menu again, and tapped Privacy Policy from there. Now I'm into Chrome! Opened Chrome without signing in, and navigated to Google.com.
6. From Google.com, searched and then downloaded apk for Test DPC app. Installed Test DPC and set myself up as the new device owner.
7. Now that I'm the device owner, you'd think it would bypass the Google account verification requirement in HWStartupGuide, but no dice. So, rebooted, took same steps to get back into Chrome. From Chrome, I was able to get to the stock Google device search and navigate to the Settings app.
8. From device Settings app, changed settings to allow installations from unknown sources, then I set the option to allow USB debugging, and opened up the dev options to select "Allow OEM Unlock" in preparation for unlocking the locked bootloader, using the unlock code previously sourced from the official Huawei EMUI unlock code site.
So, to sum up, I've got access to the device in general, can use the web and all the apps on the device, and was thus finally able to disable HWStartupGuide to prevent the previous headache from cropping up again. Here's where the impasse starts.
I have Android SDK and everything I need on my laptop (to the best of my knowledge) to facilitate unlocking, flashing, and all the other fun stuff we love to do with our phones.
I was able to confirm the USB and Android drivers are correct and working fine, as I got both fastboot and adb to recognize and list the device when connected via USB cable to the laptop, and it worked both in command prompt and in PowerShell. Fastboot and ADB commands appear to work when facilitated and entered correctly. That is...UNTIL I tried to use the "fastboot oem unlock <unlock code here>" command. It just says "FAILED" with no error code. I tried this from my stock boot options screen (the screen you get when you boot or restart with power and vol-down pressed), and from the stock recovery screen, both to no avail.
This is where I'm all twisted up. There either doesn't appear to be a true bootloader screen to navigate to, or it's purposefully inaccessible, and I don't know how to get to it. If you do a "adb reboot bootloader" command, it just reboots the phone to Android home screen. The only options from the boot options screen are "Power (turn phone off), "Start" (boot to Android home screen), "bar codes" (screen that shows bar codes for the phone's IMEI, Serial #, etc), and "reboot recovery" (stock EMUI recovery screen), where the only options are 'Wipe/Factory Data Reset," "Wipe Cache," and "Reboot."
I feel like if I could get to a true bootloader screen that allows me to enter adb or fastboot command strings in such fashion that you can enter it and then see the process play out on your device screen, then the unlock code from Huawei would probably work and the bootloader would be unlocked, thereby allowing me to root and flash a better ROM, or at least eliminate bloatware and optimize the device for performance. But for whatever reason, and I assume it's purposeful on the part of TRACFONE/StraightTalk, tbh, there isn't a fastboot-capable bootloader screen like my years of using HTC phones taught me to take for granted.
So there I be...stuck, even WITH the unlock code from Huawei! What a crock! I know TMOUS will apparently unlock it in a month or so, but to me, that's not the point. I should be able to accomplish it on my own with the unlock code I got from Huawei. And that's why I'm throwing my hands up and begging for help.
Is there anything else I can try? Is there any other devious way to perhaps flash a different bootloader interface onto the phone that would allow me to use fastboot commands properly? Is it possible to mount the SD card from bootloader and push an apk to it that would install some kind of generic bootloader screen? I'm now a little out of my league, but I am willing to try just about anything that anyone thinks might work. Any advice or suggestions warmly welcomed...not worried about bricking the phone or anything, as it's not much better than a paperweight in its current form anyway.
Thanks!!
