Bootloop and other problems

Hello everyone,
I got a little problem with my Nexus 4 and that is that I can not boot my system anymore. An Android 4.4.4 factory image is already on my internal SD card but every time I try to install it TWRP says that it failed because it was unable to mount/usb-otg. Does anyone know how to fix that? Already tried with Wug's NRT but when I use the '' Flash stock + Unroot " option my device also ends in a bootloop.
Help would be appreciated!
Cheers

unable to mount usb-otg isn't an error that would cause flash to fail and is quite normal. You can't flash a factory image from TWRP however. You use fastboot mode and a pc.

This is a guide for how to use fastboot to flash the factory image: http://androidforums.com/threads/guide-how-to-flash-a-nexus-factory-image-manually.706533/

Thanks for replying!
Now I got the problem that I can't flash the bootloader. Everything works until I type: fastboot flash bootloader bootloader-mako-makoz30d
Always responds with: error: can't load 'bootloader-mako-makoz30d'
All files are placed into one folder thus it should work shouldn't it? Anybody knows what I'm doing wrong?
Cheers
Never mind, just forgot to type the ending .img
Worked, thanks for helping me

Help. OP2 won't boot past initial logo.

Hello. I have a OP2 and when I tried to install the O2 marshmallow beta it just stoped booting and I can not boot into recovery either. I have tried going flash TWRP through fastboot but the command prompt says error can not open file. I would really appreciate some help thank you.

Please use search function, I'm not gonna add to this channels duplication misery and therefore making it worse.

Have you tried reflashing the recovery?
Code:
sudo fastboot flash recovery recovery.img

Help Please! - Mate 9 Softbrick

Hi All,
I flashed oreo to my Mate 9 today, all was well until I tried to root.
Now it won't boot, stuck in bootloop. I can get to Fastboot and TWRP Recovery.
Tried to reflash, but now no bootloop - just got fastboot and TWRP.
When in TWRP device is not showing up in ADB devices, so can't push anything.
Any ideas as to how to come back from this?
Thanks.

Things are worse now... it won't reboot to recovery. Can still get fastboot though.
When reboot to recovery it just sits on "your device is booting now..." and doesn't seem to progress. I have re-flashed TWRP via fastboot... but still the same.

Device shows phone and FRP as unlocked.
I have extracted the oreo update using a Perl script i found on another thread. Flashing system, kernel, recovery_ramdisk has made no difference.
Anyone able to help please?

What root did u use magisk or su?

Why don't you use this method?
Its safe and no more side effects.
Then after you can root with magisk.

Failed to upgrade; Only fastboot and stock recovery.

---EDIT, FIXED IT ALREADY, MORE INFO BELOW---
Dear members,
A little background; The installation of the latest Oxygen os (zip on storage - > twrp flash) failed.
I thought it was a good idea to wipe everything and reboot to start fresh.
Upon reboot I was unable to enter TWRP, only fastboot was possible.
When I flash twrp (by neither clockworkx or the bluex) the flash is successful but I cant boot into the recovery, also not by directly using fastboot boot recovery.img. When booting into recovery I get a black screen with only a white led.
So I decided to give the stock recovery a try and that one does boot up however I cant flash anything. When I use adb sideload it loads the file fine but then it errors with no error message.
I am getting suspicious that my internal memory is now corrupt so I am willing to give this msmtool a try which I have never touched so I would really appreciate some guidance. Anyone with any ideas? Thanks a lot in advance.
Other things I have tried:
I tried to flash the stock boot.img from the oxygen os using fastboot but it doesnt seem to be the problem.
---FIXED:---
Thanks to the wonderful documentation found at : /oneplus-5/how-to/guide-unbrick-guide-hard-bricked-t3761706
I was able to fix it. If you are in the same pickle head over to his thread and thank him.

My Redmi Note 7 is stuck in bootloop

Hi everyone,
I've recently rooted my phone and it went pretty much smoothly but i installed an app to change my emojis (i know its dumb but dont judge me ) and i needed to restart my phone so i did it but then my phone was in bootloop.
So I've been on the internet this whole day trying to figure out a way to get my data back and most importantly get my phone back to working.
But i didnt find anything that worked for me, ive tried flashing a fastboot rom but as i was the flash_all.bat program it just crashed so i tried MI Flashing Tool and there i got an error saying "cannot load 'C:\backup': No such file or directory"
Guys i'm desperate its my only phone and I cant afford another right now so any help is grantly appreciated.
Thanks for the help.

U unpack the rom and choice the right direction

You need the boot image of the OS and flash it via fastboot using "fastboot flash boot boot.img" make sure you use the boot image of whichever OS your phone had (stock or custom).
If similarly, the system partition is causing the problem then you need to get the system.img flashed using "fastboot flash system system.img".

We don't even know if his bootloader is unlocked or not.
EDIT: Don't mind me, I don't know how to read.
