[Q] LG Lucid 2 (VS870) Wi-fi & Un/rooting issues

I've encountered a problem that I'm thoroughly convinced no one can help me fix (mostly due to the amount of time I've already put into seeking a fix). I recently rooted my phone, and it worked, but now I am starting to experience problems. I used VRoot to root the phone. All of the problems I'm experiencing happened after an attempt to boot my phone into recovery mode using the ROM Manager application.
PHONE INFORMATION
Model # - VS870 4G
Firmware - 4.1.2 (Jelly Bean)
Kernel version - 3.4.0-g2696711 [email protected]
Build # - JZO54K
Software version - VS87012A
Issue 1:
My phone no longer connects to wi-fi. Upon selecting the connection and inputting the pass-code the phone only saves the connection but makes no attempts to connect. It can't possibly be the router that is causing the issue because the phone was able to connect flawlessly before I tried booting into recovery mode.
Issue 2:
My phone's status is currently "Rooted" but it doesn't behave like a rooted phone. When attempting to install applications that require root, the applications insist on informing me that my phone is indeed not rooted. When attempting to re-install lost applications after the numerous amount of hard resets I've done, the applications are shown to be already installed yet they are nowhere to be found on the phone.
Issue 3:
Even after installing the updated USB drivers (and multiple re-installs) any computer I plug the phone into refuses to recognize the phone if it is in Emergency mode, yet it is still recognizable in the default mode.
Issue 4:
In order to install apps, I have to download the .apk file because my phone will not connect to Google Play even when I'm directly connected to the internet via usb or using 4G. Various other applications that require an internet connection refuse to work as well which is making the troubleshooting process extremely frustrating.
Fixes I tried -
Reboot, hard reset, battery/SIM/SD removal, selecting the "Avoid poor connections" option, reset router, re-setup wireless connection (tried without a pass as well), switching the IP setting to "Static" (doesn't allow me to select connect if it is on static), toggled the 802.11g only mode, toggled the routers DHCP server option, unrooting phone (SuperUser deems it impossible due to the lack of a su binary, which I don't understand seeing that when the phone is in emergency mode the status of the phone is "Rooted"), installing a stock firmware install via KDZ, as well as failed attempts to manually install CWM (my purpose of trying to manually install CWM is due to a lot of the fixes I found having "being able to boot in recovery mode" as a requirement, which my phone lacks)
So here is/are my question(s):
If I'm not able to unroot the phone, is taking the phone to a manufacturer no longer an option?
Is there a way to "reset" the wireless hardware/software on the device directly that works around my current issues?
Are there any alternatives to installing the KDZ stock firmware file where the device isn't required to be in Emergency mode?
I'm still not exactly sure what a su binary is but is there a way to install it independently?
Thanks in advanced~

And the intricate thesis pattern.

Any luck? I am having basically the exact problems you are talking about and was wondering if you found a fix or what you ended up doing. Thanks.

do a rollback is needed

[Completed] Can't access phone due to screen lock from Android Device Manager unable to reset pw

Basically what had happened was I was out on Friday night, drunkenly gave my phone to my friend to keep safe, and then totally forget about it. Fast forward to me panicking and immediately setting a password lock using Android Device Manager. For some reason when setting a password remotely from your PC it can be as long as you want, but when typing it in my phone there was a limit, meaning I could not get in.
Why don't you just use ADM again to reset your password and put a new one?! Well apparently they don't let you form a new password once there is one already locked on your phone. Why don't you try unlocking it via findyoursamsung?! I didn't create a samsung account when prompted to. (hindsight is 20/20)
I also tried some other third-party backup apps such as Kies3 and Samsung Watch, both of which required the phone to be unlocked to function - which is also why I can't simply just connect my phone via USB and drag the data into a folder.
This lead me to doing a ton of research and it seemed the only way to get my pictures and videos back without resetting my phone would be through those coding programs and ADB and such. I am not well versed in this area at all so I looked at a bunch of sites explaining what to do.
From my limited understanding, it came down to a few things:
- My device is a Samsung Galaxy S4, probably kit kat or jelly bean. It is neither rooted nor does it have the "USB debugging" enabled
- I have successfully installed CWM (clockwork mod) and ADB (android debugging bridge) onto my computer/phone because apparently when CWM goes into recovery mode, the debugging is automatically enabled, where I'd then be able to unlock the screen (but I don't seem to know how to input adb commands - where would I do this?!)
- I installed a few other programs that were of no use to me because I had (almost) no idea how to use them (Cygwin, Odin, JOdin3, Heimdall) in conjunction with ADB and the "Download" mode on my phone to flash CWM to be my "custom Recovery" instead of the stock recovery
- I saw there were some third party apps that would automatically (?) unlock your phone screen for you but I wasn't too keen on trusting them seeing as most of thm were outdated , so unless you guys recommend one I would rather not download those
- I think my main issue is not knowing how to simply bring up a terminal and input commands but sometimes they wouldn't even recognize my device (probably because USB debugging is disabled)
I have been infront of my computer for almost a whole day now trying everything and reading everything simply trying to figure out what to do. I have looked at way too many guides and could probably recite them to you. I guess the point of this is I really would prefer not to lose this data as it has a lot of sentimental value, so I'm straying away from those methods that require you to wipe your phone. If any of you know any helpful sites or guides (I probably have seen them) that explains things very formally and easy to understand, let me know, I will be forever gracious for your help.

Hello, and welcome to XDA!
A bit of a doozy....
This thread may help:
> Samsung Galaxy S 4 i9500, i9505, i9505G, i9506 > Galaxy S 4 Q&A, Help & Troubleshooting > [RESOLVED] HELP please!! Unable to unlock device locked by Google Device Manager
May need to modify solution two to use under CWM. That is, mount data via adb (or via recovery if there's an option) before issuing (the rest of) the adb commands.
By the way, here is a primer to adb:

Broken Screen, how to get to my files? Need an android expert!

Hello everybody,
I know there are many threads with broken screens and so on, but I've been searching the internet the whole day & night and tried nearly every solution.
My Smartphone fell on the ground two days ago, I can see everything, but touch isn't working anymore.
Usually I'm rooting my phones but i didn't root my XZ5 so far (big mistake!), so I don't have a custom recovery.
I have USB Debugging activated, but I haven't connected my phone since it updated to the new firmware, so I'm getting RSA Fingerprint Message which I can't allow.
After my Z5 fell on the ground, the fingerprint didn't work so I had to restart my phone - now I'm forced to enter the key to unlock the system.
At first, I tried "Android Control" with adb, but when I connect my phone, adb says "unauthorized" - no remote control possible.
After that, I bought a OTG Cable and plugged in a mouse. This isn't working, because I have to search for a plugged-in USB device first in the settings (the phone doesn't recognize the USB device itself).
Fastboot & Flash Mode are still working.
Is there a possibility to skip RSA Fingerprint with USB debugging or deleting my lock screen? I thought of unlocking my bl and installing TWRP, but then the mobilephone would be wiped as far as I know.
Maybe someone of you knows a "temporary recovery" which can be booted from SD-Card or another way to get to my internal data..
It would be awesome, if someone could help me with this!
Many thanks in advance!

Only way i can think of are to downgrade to lollipop with flashtool without wipe.
Then the usb mouse should start to work directly if im not mistaken.
Atleast i think it was this they before mm upgrade.
Did you try to boot the phone with the mouse connected?

yes, unlocking would completely wipe your phone, including internal memory so it's not a solution.
Rsa key request means you cannot run any adb command right, included adb shell right?
Did you try to do an extensive google search with "broken screen rsa"?
Particularly, http://stackoverflow.com/questions/...b-rsa-key-with-broken-touch-screen-on-android
talks about rebooting in "recovery mode", so you could try to use adb commands in fastboot mode (or download mode)

So I recovered my password from the dust and figured this is my chance to help..
Better be working..
I dropped my z3c while I was holding my newborn baby, it contained all the pictures from birth, ****ing fool I am for not backing up..
Get that short '.. to usb' - thing from the box. Use that to connect your Bluetooth mouse and tada that should work. Use it to unlock your phone and do you what you want to do.
It worked for me, hope I can help you.

Tool for unlocking Android pattern\bypass google lock screen

I recently got locked out of my phone with debugging off,no wifi and no root.
Since i see lots of the same question i'm posting another tool i found for all those in need.
If you are also locked out with none of these options there are a few steps you will have to take first
I followed lots of helpful tutorials here on xda which led me to:
1- CF Root phone through Odin,doesn't require debugging on. (CWM included)
2-When in CWM recovery use ADB to activate USB Debugging.
(You can also try to turn on wifi etc and see if that solves it for you)
Unfortunately i was not able to unlock my phone in ADB although maybe for some different models the adb methods might work. Allthough i was able to remove the lock screen in setting,in my case i still got the email lock screen even after the pattern was removed.
But with Debugging on i was now able to use this wonderful tool created by GSM EXTREME.
It really is a one click unlocker.
I was not able to find version information but this is the latest one i found.
You can download it here

If you have a custom recovery installed, you can use this zip to bypass the screenlock.

Trying to downgrade from Android 12 to 11 but Pixel keeps changing the USB setting when it reboots into the bootloader

As the title implies, I'm trying to flash Android 11 to my brother's Pixel 3 because he didn't like Android 12. I've trying manually doing it with the ADB tools and with Google's browser flashing thing. The phone has USB debugging and OEM unlock on as well as the USB behavior set to File transfer as default.
It gets recognized fine at first and is able to reboot into the bootloader using command prompt and whatever Google's website does but once it is there, the phone changes the USB behavior. I hear the little sound that Windows 10 makes when you plug in and remove something and the phone is no longer present in Device Manager. Google's website also has me reselect the phone because it gets disconnected but it is no longer there to be selected. Tried doing it with my own Pixel only with the ADB tools and the same happens. Once it is in the bootloader it is not recognized. Any ideas on how I fix this?

Not sure this will help you, but why not do the firmware transfer via fastboot? All the directions are there with the firmware, you do have to unlock the bootloader, but can relock just after.
I haven't actually done this procedure going from 12 to 11. But have used it to go up, and also to go from lineage back to stock firmware.
cheers, good luck.
