Lg K7 Unstable connection avoid flashing - LG K7 Questions & Answers

Hi , I think I probably f*kc up something. My sister just changed his phone to a new one so I borrowed his old Lg K7 x210 3G (I just post all the info I have about the model cause I don't really know exactly which one is) Well I unloaded the Bootloader and tried to change the recovery. I fallowed the steps of the guide but at the end I finished having the "No Command" error . This got me nervous and I started to touch things without knowing what I was doing (really, REALLY bad idea )
So the phone got stuck on a bootloop , well time to flash to get rid of the loop. The main problem is that I can't flash anything (except for the preloader) because it disconects all the time. I installed 20 different drivers and Sp Flash Tools versions (erasing the old ones with USBDeview )
These are the two states that jumps every 2 seconds.

What can I do to avoid this "jumps" and flash the rom correctly to the phone?
I tried 2 different pc , all the ports in this pc and all the cables I could find at home
PS: This are the different guides and tutorials I tried but failed.

Thanks for your help . I don't want to give so early I think it could be fixed.

[Q] Flashing Basics, who can tell?

HI,
After flashing a numerous HTC HD2 and Note N7000 i got now stuck with a Chinese Clone.
I flashed a lot of ROM on this phone and finally i got one working with playstore and working IMEI (which disappeared after the first flash)
I probably made a mistake to choos Format All in SP Flashtool and flashed the latest ROM that was working. All went fine and he started.
Then something strange happened. The whole touchscreen is working but on the wrong places, i can activate all menu's etc. But i have to click in the middle to get up and the back and menu touch are just on the screen not on the bottom.

Looking at flash tool it has a warning with manually format that calibration could be lost, is that what happend ?
I tried numerous other roms the install and work but not the touchscreen.
I found out which displaydriver i got (1-nt35590_hd720_dsi_cmd_truly) but no corresponding ROMS for my phone but ROM for other phone
Can somebody tell me if they should be mergable? Or how to flash the calibrationdata ? I inserted other nvram.img files with succes to get an IMEI. Is there a files i have to insert to get the correct LCD/Touchscreendriver?
I know that there are 2 preloader type that make my phone alive. After reading many hours i suspect that uboot.img could be the file, althugh i now come across ramdisk.img
(YES I WAS STUPID ENOUGH TO FORGET TO MAKE A BACKUP OF THE ORIGINAL ROM)
After four week straight in a row testing more that 50 ROM and not getting the original from seller the phone is send back to china. I looks like a hardware failure

LG Stylo 3 Plus stuck at boot

So, I decided to delete some bloatware, ended up deleting the bloatware that kept my phone running and now I can only go on TWRP, I have no backup and LG hasn't released the stock yet so I guess I have to wait for my dead phone to get a stock rom? That is unless there's another way?

LG Mobile Support Tool Errors out. Extracted KDZ image for system.img cant be flashed with TWRP (Something along the lines of the file being too big).

Note 5 possibly bricked/droidcam

I have an old Note 5 lying around with a cracked screen. Not worth using except as a backup, not worth selling. I had a great idea: use it as a webcam!
I downloaded droidcam, used it a few times, forgot all about it. Until yesterday.
I turned on the phone and the screen was as in the attachment. I used Android Control to mirror the screen to my PC (effortlessly) and make sure the phone was actually working. I figured that the last time I used the phone, I had actually left the phone connected to droidcam for a long time (forgot about it) and it may have done something to the display driver or some such. No biggie, I'll just reflash, maybe it'll solve the problem, maybe not.
After some struggle, got the phone into download mode and used Odin to attempt to flash 3 different firmwares, all for my SM-920 XSG (UAE firmware). The first time it made it all the way to the end when it failed to write. The other two fail early on. I even attempted to flash a PIT, which worked and then everything failed after just as fast as before the PIT flashing.
So, anyone have any idea what's wrong with the phone's screen? It was working before and literally had been left alone on a table undisturbed. Also, it would be nice to unbrick the phone, so that I can donate it (as a working phone sans screen) or at least try to sell it online to someone who would fix the screen (or a local shop).
You don't tell me nevermind

Unable to transfer files to PC

Hello. I own a Xiaomi Redmi 7A. Since the very beginning I have issues transfering files to PC.
First of all, the device barely loads on Windows 10. Whenever I try to move files or even simply open folders, it freezes. Never had this problem before with any Android device, either from Samsung or LG. Or whatever other brand (not even those cheap Chinese freaks).
But whenever I connect my 7A to PC, I have to quickly try to move files before 30 seconds or so. After that, it totally freezes. Or files don't respond. Or explorer.exe doesn't respond.
I have tried reinstalling drivers, activating debugging mode and tons of other things I could find on internet, having NO success at all. Tried with my mom's laptop (Windows 7) and I was surprised I got the exact same problem. So, I came to this forum, cause I believe you guys are the only one who can save me.
I didn't want to get a new phone, because I got this one only 4 months ago, so... But seems like I'm going to have to get a new one asap.
Examples of the dozens of problems I've been experience:

(Failure moving File or Folder - Catastrophic failure)
(Hanging forever/files don't show)
Eternal copying (that can't be cancelled and still freezes)
Some more different errors (googled it and no success finding a decent fix)
Seems to be a mass storage bug with either the device or Windows

LG L3 II won't (kinda) boot

Hi there.
I just want to make some premises:
-The device is NOT rooted
-The device was NOT flashed or been modified in any way
Anyways,
I just picked up this phone after some years of being in some boxes, and wanted to see if it still works.
Here's what he does in booting:
-Logo
-Logo with screen less brighter
-Vodafone animation (yeah, my phone is branded)
-Stuck (like the image)
-Home button light still flashing tho
I tried to hard reset it, it kinda works, by booting, going into the setup, and 1-2 seconds later it boots itself straight into the animation (yup, no logo) and remains stuck.
I seriously don't know what to do.
Can you guys please help me out?
Thanks in advance

in short, no
[FIXED]
so I recently fixed, here's what I did:
-Downloaded and installed KDZ;
-Picked my software file (un-branded, while I were at it)
-Opened KDZ with Administrator Privileges (very crucial step, or else KDZ will crash for some unknown reasons)
-Flashed
-Waited
-Done
