[Q] Help! Problems with fastboot

Hi
1.- I want to install a new Rom (Android 4.4.2 KitKat omniROM)
2.- But first I need to install TWRP (.blob), so I need to install and run a fastboot tool (Minimal adb/fastboot tool)
I unlocked the bootloader of the tablet
I install the fastboot
I install the drivers of the fastboot of the Asus
I copy the file.blob to the same folder of the fastboot
I open the fastboot and in the CMD I wrote ''fastboot devices'' and it find the Asus so in the screen was numers and letters like a code...but then I wrote the command Fastboot -i 0x0B05 flash recovery file.blob but then give an error (failed....(no such device or address))
I tried all to solve this problem but I cant.. so I need your help.
I tried:
■Reinstall fastboot tool
■Restart the tablet
■Use all the usb ports of the PC
■Reinstall drivers
■Used apps like SDK Manager
■Used other usb cable

Is your bootloader unlocked?

I'd say try to use a completely different USB or computer. If that doesn't work, you can actually flash it from the system itself if you have root. Can't remember the command. Give me a second.

To install without using fastboot, download twrp, make sure its one of the newer twrps, I think 2.7 and above is required for KitKat, and..
[QUOTE/] Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.blob
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Then reboot to complete installation.

So, yesterday I clean the Asus Cable, the port of the pc and the port of tablet and finally works, so I flashed my tablet with TWRP recovery and the 4.4.4 omniROM Nightly.
The all problem was the cable and the ports.

Phone only booting in fastboot or recovery

*edit*
Got it working, I installed a rom with ogt.
I accidentally flashed twrp twice, and for some reason now it won't boot into the system. Everything I've read says to download an official image from https://developers.google.com/android/images and running the bat.
But it only has

Click to expand...

No img or bat like everything (including the page where I downloaded it from says)
I tried a few others and they were all the same.
Also adb devices shows up as blank. I've tried unplugging and re-plugging the phone, killed adb, installed the driver, and ran cmd as an admin but still devices is blank.
**edit**
I just realized I wiped my phone disabling usb-debugging which would make adb not work,

LGMS631 MetroPCS LG G Stylo Backup (Unbrick/Root) Android 6.0

So, I think I've managed to salvage my bricked Stylo, I somehow also managed to root my Fiance's LG G Stylo that's on the 6.0 update... this is a guide on how to flash a TWRP Recovery I made of a rooted LG G Stylo that is running Android 6.0 This can get you out of a brick or just give your spare phone root access.
Since I can't find any ways to fix this problem on the internet I'll post what I did here so hopefully I can get some other people out of deep water with their phone.
Stylo.zip​
I'm going to assume that if you are following these instructions you have already downloaded and extracted the .zip file named Stylo onto your desktop.
All of these files are in the Stylo folder, so you should only have to download Stylo.zip
Minimal ADB & Fastboot installer
LG Phone Drivers
TWRP Backup file
recovery.img
1. Install minimal_adb_fastboot_v1.4.1_setup into the folder you extracted Stylo.zip in
(Install PhoneDrivers if you have not already)
2. Enable USB Debugging on your phone
(If you are boot looping, you should still be able to boot into the bootloader with
minimal adb fastboot just plug it in and let it do it's bootloop while you try
booting into the bootloader really quick, this may take some trial and error)
3. Launch MAF32.exe
(This is Minimal ADB and Fastboot)
4. In the window that pops up type:
adb devices
It should look like this:
PS C:\Users\Hyperion\Desktop\Stylo> adb devices
List of devices attached
LGMS6318bb1ce9a device
5. Next you will need to type:
adb reboot bootloader
Now, the powershell screen should look like this:
PS C:\Users\Hyperion\Desktop\Stylo> adb devices
List of devices attached
LGMS6318bb1ce9a device
PS C:\Users\Hyperion\Desktop\Stylo> adb reboot bootloader
PS C:\Users\Hyperion\Desktop\Stylo>
6. Once you are in the bootloader type:
fastboot boot recovery.img
(If you opened the PowerShell window by holding shift and using the right click menu,
the recovery.img file should load on its own, your PowerShell window should now look something like this)
PS C:\Users\Hyperion\Desktop\Stylo> adb devices
List of devices attached
LGMS6318bb1ce9a device
PS C:\Users\Hyperion\Desktop\Stylo> adb reboot bootloader
PS C:\Users\Hyperion\Desktop\Stylo> fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.367s]
booting...
OKAY [ 0.011s]
finished. total time: 0.380s
finished. total time: 0.379s
PS C:\Users\Hyperion\Desktop\Stylo>
7. Once TWRP boots up on your device you will need to navigate to Backup
Uncheck everything but boot
Start the backup process
(We are making a backup of boot
so we can take the name of the folder
it makes in /sdcard/TWRP/BACKUPS
and copy/paste that to the rooted backup file.
TWRP will create a backup of your
boot animation that contains your PHONE ID #
In my case it created a file named LGMS6318bb1ce9a )
8. Open your sdcard contents on your computer
navigate to /sdcard/TWRP/BACKUPS
Copy the name of the new folder that was created (Mine is LGMS6318bb1ce9a)
Open the Stylo folder on your Desktop \Desktop\Stylo\TWRP\BACKUPS
Paste the new folder name over the folder titled (Paste Here)
Overwrite the folder in /sdcard/TWRP/BACKUPS that contains
the boot animation with the new folder from \Desktop\Stylo\TWRP\BACKUPS
9. If you are not in TWRP on your phone any more, repeat steps 3. - 6.
10. Once in TWRP click WIPE in the top right, and Swype to Factory Reset
(Unless your backup file is being loaded from Internal Storage)
11. Navigate to RESTORE in TWRP, find your Backup file in the /TWRP/BACKUPS directory
LEAVE EVERYTHING CHECKED!
(If you uncheck anything the phone will not be rooted upon restore of the backup)
(Alternatively you can uncheck Data and have a fresh install of 6.0 with no root.)
The rooted backup should be installing 4144mb worth of data.
I left a few apps on the desktop that I figured would help some people out
Hope this worked for you, getting root on these phones is a *****.

I know a site that has the QFIL files necessary to actually unbrick a hard bricked Stylo H631. I'm not sure if I'm allowed to link them ..but I will tell you they charge 11.99USD. I'm hoping to have the $ to do it Friday...if I can...I'll give it a try and post findings here

I'm still waiting from someone in the comments from that site to confirm it's not a scam.

I need to find out the pin test spots on the h631/ms631... anyone know of a diagram or schematic floating around??? If so, I may have this figured out...don't want to poke around on my only board and make it completely useless

ya gotta check all the boxes possible after going into the MOUNT options when in TWRP. always before doing almost anything in TWRP. sometimes its persistant, sometimes not depending on device.

I can't seem to get my T-Mobile Stylo 5 to go into fastboot mode. Adb reboot bootloader just reboots the phone for me. Maybe a downgrade is required?? Also I just used platform-tools adb and fastboot. Build# PKQ1.190302.001
