Neverending series of problems

I am almost getting to the point of blowing this entire thing off out of pure RAGE. WARNING: LONG POST AHEAD!
Now where to start...
My LG Optimus V via Virgin Mobile has been having every problem in the book lately. I have retrieved a new one from Virgin itself, so that should take care of the problems with calling and whatnot.
However, there are a few pretty major problems with the old one. Okay, QUITE a few.
Here is a list of my old phone's problems:
SD card slot will not read anything
Phone will not connect to computer via USB
Phone's Bluetooth is not recognized by computer ("Unable to get Bluetooth FTP Remote Folder content. Please check that your device is turned on and working properly.")
Phone will at times say my memory is almost full when at other times it says there are 8 more megabytes left
Phone's keypad will disappear in-call and will not return, making it impossible to check voicemail or dial extensions
I have installed the drivers direct from LG. I have tried booting in recovery. I have tried uninstalling and reinstalling those drivers. I have tried booting/rebooting with all kinds of random patterns to the point that my headache has amplified. I have tried to hack the connection settings with an SQLite app. I don't even see an option for USB connections except debug mode. I have tried Bluetooth through Total Commander. Absolutely nothing I find is working to get me anywhere.
For the record: My computer is an ASUS laptop with an i7 processor and Windows 7. I have tried this same USB cord with my previous phone (a Samsung Captivate that also has issues) and it works fine. Also, my phone charges through the USB port, but it isn't recognized by my computer.
Given this entire list of problems, there are a few things that are suddenly becoming impossible to do since the backup routes are blocked off. Firstly, I want to transfer my data to my new phone so it's like nothing happened. Now, this is more a "want" than "need" but it certainly would be nice. Therefore, I need to get my USB setup working. I have Googled extensively for answers... and haven't found any that work. Which is ridiculous because I feel like I'm in an extreme minority... because the answers are working for others.
Eventually, I unpack ADB and...

Great. Just bleeping great.
Second, I need to unroot my phone before sending it to Virgin. I don't want to get in trouble with them. So once I have my data backed up, I need to work on reverting the phone to stock - a factory reset and an unroot. That is impossible without being able to connect to my PC. Like... I have these saved but can't start the operation:

http://androidforums.com/optimus-v-...uide-100-stock-lg-optimus-v-all-versions.html
See, I have found plenty of answers for each individual problem, but everything tends to overlap. I have completely confused myself. I am getting a headache from all of this new terminology to me and all of these different answers...
The first step should be trying to figure out why the phone isn't connecting to the computer. That may resolve a slew of other issues and allow me to run ADB. But I'm fully prepared for that not to get me anywhere.
What can I do? Where should I begin? Is there anything that's even possible with this mess? Anything to go on would be greatly appreciated! And feel free to ask me any questions you have about it - I will do my best to answer

you mentioned that your phone is rooted, and I suppose that you have recovery, so try this, connect phone to pc trough usb, boot into recovery, go to mounts and mount usb and see if your phone is recognized by pc(try LGMDP and if it does, update it, but you must have ADB enabled in phone settings development) and pop up the window with sd card content

Booting into recovery and doing that got me this:
E: Unable to write to ums lunfile (No such file or directory)
I couldn't mount "system" either. Well... maybe I did, but it didn't do anything?
Great. Just great. I am lost and confused like a little puppy dog right now... :/
I appreciate your suggestions. Thanks!

Spent close to 100 hours looking for drivers for H950. Need Help!

Hello everyone,
I bought this phone on sale last year and it was advertised as follows...
Refurbished: LG G Flex2 H950 32GB Unlocked GSM 4G LTE Octa-Core Android Phone
In browsing the forums here I see the excitement around this phone has waned quite a bit since it's release, but I'm hoping there's still a few of you left who might be able to help me. I totally love this phone and want to be able to use its full potential.
It's branded as an AT&T phone when the boot-up screen appears. I doubt it was sold as unlocked by AT&T, but rather Newegg, or someone they're reselling for, unlocked it. I've never been an AT&T customer. I bought it knowing I could use any carrier willing to sell me a sim card. I'm currently using Mint.
It came with the 5.01 firmware. I've spent many days reading every thread I can about how to upgrade it, and possibly get Marshmellow as well. The issue is that I can't seem to find any drivers that function properly. Here are all the ones I've tried...
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The only one that's come close to fully functional is the top one for version 3.11.3.0 It's the only one that recognizes all of the sub-devices no matter how many times I unplug the USB cable and plug it back in. The only other one that came close was version 4.2.0
I use a program called USBDeview, which provides live monitoring of USB connections and shows a great deal of info about each one. In the images I'm going to share, I've shrunk away all of the columns except the ones I think are most relevant. The ones with Green dots mean it sees them as a working, connected device. The ones with Gray dots mean that there is a record of this device connecting, but that it does not see them as currently connected. And the Purple dots mean it sees the device as connected, but that there is some issue with its functionality.
Here's the result when I use the 3.11.3.0 driver...
All 5 devices show green and everything action I've tried to perform from studying guides here works perfectly. And, as I said, it keeps working no matter how often I reconnect it. The only weird thing is that USBDeview reports the version as 3.11.0.0, even as the filename and the file properties report it as 3.11.3.0 It reports correctly for all the other drivers I've tried, but I guess it's nothing to complain about at this point.
The problem is that whenever I put the phone in “Firmware Update/Download Mode” I get this result...
The LGE Mobile Sooner Single ADB Interface driver now shows as disconnected, and as such, I can't send any ADB commands and my device doesn't show up on the list when I type "ADB Devices". It doesn't indicate there is a problem, it just shows it as not there. This issue is thwarting all my efforts to upgrade the phone.
With the 4.2.0.0 driver, I get a similar, but slightly different result. Sometimes I got this when connecting the phone in normal mode...
And other times I got this...
I can't account for the different results because I was trying all kinds of tweaks and fixes between different attempts. But one thing was universal with this version: They would all show green for up to a minute or so and then all but one would start disconnecting until it looked something like this...
The other drivers I tried were similar. Some recognized more devices, some less, and some would look like the above on their first use. Some were consistent and some would look okay for a minute and then disconnect.
When it came to Download Mode, some would see the ADB driver and some would see the USB driver, but I still haven't found one that will see both. When I check the error logs, I most often see something like this...
So if anyone has a driver that they know works on this phone and has definitely used it to upgrade this model in Download mode, please let me know.
Also, if you know of a method to accomplish my goal without using Download mode, please point me to some steps to that method.
Just to avoid the obvious advice, I've tried a great many fixes...
Turned off Fast Startup.
Disabled ability to turn off device for power savings on all USB hubs.
Disabled USB Selective Suspend.
Disabled firewall and all other protection settings in Windows Defender.
Uninstalled my anti-virus.
Disabled Windows automatic device updates in Group Policy.
Made sure all my other devices have the latest drivers.
Update my BIOS to the latest version.
Windows 10 Pro is up to date.
As one person advised, tried to manually update the devices that wouldn't connect using lgx64bus.inf from the driver folder.
And various registry tweaks.
Thanks in advance for any help.
NOTE: In going through all the drivers again, I discovered that version 3.14.1, at least on the surface, is performing exactly as ver 3.11.3 has been. Works perfectly in normal mode, missing ADB device in Download mode. Guess I skipped it in my first few runs. Still doesn't solve my problem, but I strive to be accurate.
NOTE 2: I have found a method for flashing that does not require ABD to flash my phone. I can't find an option to delete this post, so the moderator has my permission to do so at their discretion.

Screen is broker, how to backup phone?

Hello everyone,
dropped my phone on Friday, didn't have a single scratch. But the screen didn't turn on, just had first a weird green line on top of the screen.
Brought it to a repair shop, they said the screen is burned and has to be changed.
First the positive things:
- phone is still running (LED, vibration, finger sensor, etc.)
- has internet access (could yesterday use WhatsApp Web)
I didn't backup all of my pictures, a few apps, screenshots etc. So Best solution for me would still be to have a functioning screen. The local repair store checks if the screen is available and how much it would cost.
Do you know what else I could do? I mean the phone is 2 1/2 years old, so I could also replace it, but I want to backup all of my apps and files.
I already checked adb, the device is listed but "unauthorized".
What options do I have?
Thank you and best regards

If the digitizer (touch) works, do what I recommended here:
https://forum.xda-developers.com/oneplus-6/help/broken-amoled-digitizer-data-recovery-t4160245
If it doesn't, you're going to need a USB splitter to connect both your phone to your PC and a mouse to your phone in order to confirm the adb authorization dialog (or at least that's the only idea I have at the moment). And a lot of luck to click where you're supposed to click. But yeah, it might work.

Ah, he has the exactly same problem
I like the idea with scrcpy, that would fit my needs to backup everything and then I can take a new phone. The problem at the moment is that I seem to be unable to press the button to authorize the phone.
I didn't get the idea with the USB splitter? You mean to connect a screen and a mouse to the phone? I tried with a USB-C portable screen, that didn't work. Is this possible with a splitter?
Do you mean something like this here:

Using the splitter for simultaneous mouse and PC connection is exactly what I meant (the one in the picture is absolutely fine), albeit if your screen is completely dead, and the digitizer is broken (or so it seems), it's going to be really hard to click in the right place, I think.
As for the portable screen, OP6 doesn't support video output via USB-C AFAIK, so that's why you didn't have any luck with it (a splitter won't help with that). Technically you could use a displaylink device to mirror your screen, but I feel like that's just too much hassle.
Eh, I think I'm out of ideas for now. Maybe somebody else will be able to help. Hope you get your issue solved!
EDIT: I think I have an idea on how you could check whether touch actually works or not. Do you, by any chance, have touch sounds on? If yes, you should be able to hear a sound for every action you make on the phone (like opening an app and such). Just make sure that your phone isn't muted beforehand
EDIT2: Oooooooor you could just use a keyboard to confirm the dialog/input the code in TWRP if you have that installed (and if TWRP actually supports keyboards). Also worth trying.

Thank you so much for your propals! So finally I could make it run, I didn't start ADB, but I started directly ScrCpy and somehow on the phone pressed the button to accept the notebook. Since then I can connect with ScrCpy and now I can do my backup like that!

Cannot Unlock Phone - Cannot Update USB Driver - Resolved

I've read other posts, applied some of the suggestions, but have not been able to solve this issue. I have the current Mi Flash, I have added my account to Developer options, enabled USB debugging. added Mi account to Mi Unlock status, and oem unlock, I have turned off wifi and am using cell data. My Mi account is OK, Sim accepted. I hear the Windows notification when I plug in the phone. I don't see the phone in Explorer when I'm in bootloader. I do when the phone is not in bootloader. I have logged into Mi Account with my phone # and email address - same error either way.
Issue, I start Mi Flash and after signing in, this message briefly appears on the screen, "Checking if your Mi Account has permissions". This message disappears and then Mi Flash goes to the next screen. I follow the instructions to the letter and finally plug my phone (several times) in (it is bootloader). The Unlock button on the bottom stays grey.

I wait and wait and it doesn't change. I open settings, I click the button to install the drive - I get an error:
At this point I'm stuck. I'm not sure its a driver error - the phone connects to my laptop OK and I have been able to transfer files. MTP is set default to "Transfer Files" vs charging.
As an update, I found the Poco in Device Manager, Portable devices with the following driver:
I'm guessing that this might not be the correct driver, but am not sure.
I would appreciate help with this problem. I hate the bloat Miui serves up and would like to move on to a ROM that it simple and safe. Thanks

I can't unlock too

I'm still trying to figure this out and need help. I connect to the phone through USB OK. I can access it via file explorer as a drive labelled Poco X3 NFC. I can add files via explorer and search through the phone. However, I installed Mi Suite to check drivers and with the phone connected Mi Suite pops a screen that says connect to device to usb. It already is, but I unplug and plug back in anyways, same error then it changes to this:
So its odd that it connects to the PC but does not seem to connect to the internet or Mi Suite. Is there a better USB driver to use for this. I found a Qualcom driver V1 and an adb driver R-13 Windows.

Well you have the needed Windows driver than.
Check Windows app/system error messages for clues. You may be missing a MS library or such.

I'm on W7x64. Goggle it. It you use Windows you should have discovered this important system app within you first year.
Example:
Side by side errors used to be common; missing x64 MS library (you need 2, one for 32 bit and one for x64). Sometime the apk developer fails to included in their app software; they don't need as it was needed to code the app. To run the app and get full functionality on a 64 bit system you need both libraries; a simple download from MS.
Perhaps they are now included in the 64 bit OS's unlike the XPx64 days however it's also possible the file got corrupted or deleted if so.
This is the kind of critical information MS Event Viewer can show you. It records App/System/Security events with a time stamp.

OK, this is solved. This time I went through the unlock process on my wife's Win 10 laptop. Drivers loaded, windows setup the Poco. Same thing, greyed out unlock button. I clicked on the button to install the driver and this time the driver install completed, versus the error I posted above. The screen popped back to the Unlock screen, with the Unlock button live. I clicked on one confirmation screen after the other until I got the confirmation to wait 143 hours to unlock. Glad this frustrating event is over. Hope it works at 143 hours too. Of note, I did turn off wifi and used data to unlock. I read somewhere to do do that. No idea if it made a difference.

Yay! Windows can get funny about loading drivers sometimes. You just need to play with it a bit many times to resolve the issue.
Keep Event Viewer in mind though as it can show you errors that are slowing your system down, security issues and more.

Someone Logged into my stolen phone!!!

So someone decided to steal a broken phone belonging to me. The screen was smashed & im pretty sure it wouldn’t turn on, I couldn’t feel it viberate when powering on, but unsure if even powered.
Now since then I logged into the Google account & seen the device was active yesterday on a known network, I couldn’t see the name.
No SIM cards or sim tray in the phone for mobile data.
Passcode to enter the phone was my name.
Is it possible that someone powered the phone on with the broken screen there for it connected to a known network? Even possible to power on a phone with. Broken screen? Phone need to be unlocked to connect to Wi-Fi?
I am dumbfounded.
Samsung Galaxy A03Core.

As long as the SOC is intact anything is possible...

Well I know it is due to recent activity, Im absolutely sickened. Issue I have is when I last had access to it, it wouldn’t even light up when plugged into PC.
Now it’s stolen & recently active…

Some ejit replaced screen & either got in via passcode & or the Device connected to known network? Only possibility I can imagine?

why don't you ERASE DEVICE from google?

How was it stolen? Contact the police if so or if accessing your account. FBI complaint as well if needed.
Oh well... live and learn.

Pretty sure it was taken from my house, 90% sure but there is the other 10% chance it was elsewhere. I live in EU. trying to figure out how it came back online with a broken screen or is the that someone went through the effort & replaced the screen then logged in?

Yes it's doable. See what free legal avenues are available to you where you are. I would leave it be as such until you do that. Best if you can find and prosecute the offender. Hammer 'em.
Secure bank accounts etc. now. Change email address and passwords.

no need for screen unlock to connect to known wifi. it's possible to mirror screen to tv and control phone with mouse and keyboard, though

@alecxs Is that a frame buffer device there?
Which devices support a frame buffer with mirroring without doing anything?
I presume that it's not just a Type C alt mode?

Thanks for the informative reply’s il get it back somehow.

There's lots of sites saying that if it supports USB 3.1 then it supports video.
OTOH, Qualcomm has tons of USB 3.1 processors and DisplayPort alt-mode only came in on the SDM835, SDM845.
I've tried using an HDMI adapter on my SDM636 (USB 3.1) and it doesn't work.
I've no idea if the adapter converts from DisplayPort to HDMI or whether it uses HDMI alt-mode.
