Fastboot Screen & no reboot into Recovery from System

Hy,
after install some CM13 builds i see that the Fastboot Screen thats normaly only Black screen with Fastboot OEM now changed into CM Menue.
First question how i can bring back into original Fastboot Black screen.?
The second problem is that i cant boot into recovery or bootloader from Android System. I press/hold Power then i can choose recovery or bootloader, after restart automatically system restarts....
As Recovery i flashed TWRP.
When i start the Phone by pressing Vol + and Power i can go into recovery, ( this way works )
at the moment i use the original Stock ROM because the CM Builds seems not working fine with my Bluetooth in Skoda/ VW Radio.

When in fastboot do
" fastboot boot twrp-xxxx-kipper-xxxx.img "
it should boot to twrp. instead of writing filename, write fastboot boot (SPACE) and drag the TWRP file to command window. After pressing ENTER you will get twrp. Do a factory reset and flash COS 12.1.1 zip file. If you need i can give you link to it

Problems booting into recovery

Okay, to start with, I've read the other threads about this. I understand the process that *should* work:
1. Power off.
2. Then, press and hold both all Volume Down + Power buttons at the same time until the LG Logo is being displayed on your LG V20.
3. Now, release the keys and press the above combination again however, this time you should wait until recovery mode menu is displayed.
...and I've tried the version where you keep holding the Volume Down button the entire time.
So, yes, I've reached the white screen where it asks you if you want to do a factory reset. I've hit "Yes" to both questions. The problem is that it really does a factory reset then.
---
After unlocking the bootloader, I installed TWRP via fastboot:
adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot
...everything went fine.
But I can't get into recovery. And since I'm waiting to have TWRP working so that I can flash root, I can't boot into recovery via an app.
What did I do wrong?
EDIT:
Okay, it looks like TWRP isn't working properly. I tried "adb reboot recovery" and that got me to a dead Android icon and a "No command" message. I have no idea why TWRP isn't working.

to confirm, have you verified you are using the correct TWRP version for your V20?
in this step "fastboot flash recovery twrp.img" is your twrp image that you saved, named twrp.img? If its not, that command won't work correctly.
usually after I flash recovery, when still in the recovery menu, i choose reboot recovery just to make sure it did stick. If it reboots back to itself, then try rebooting the device, and again confirm with manually entering recovery. Maybe overkill but it works for me LOL.
Good luck!

I am in need of big help! I made a critical error after days of trying to navigate the minefields of rooting my device. I have a LG V20 h910 and it is no one-click wonder root. It made me work for it and I finally got it. I loaded LineageOS 14.1 and all was good until the USB OTG cable from my PS4 controller did not register anymore. Damn, that was a let down, and probably led to my careless move of needing to downgrade my TWRP, saw the version I needed, forgot these are device specific, and now I'm stuck in a hard place.
Perhaps the fix is easy, but I have not found the answer after many, many searches...
I had TWRP 3.2.1-2 and needed to downgrade to 3.2.1-0 to try SuperRom (hoping it would have OTG ability). I hastily grabbed the first TWRP 3.2.1-0, threw it on the SD card, wiped everything except internal storage, and flashed the img, and did a reboot. Road block went up.
I tried getting back into recovery, did the PWR and DOWN pressing combo and got the Factory Reset screen, but after clicking "Yes" to both, instead of getting the TWRP screen, I got this error screen (attached).
I tried another idea - hooked it up USB to my PC and tried accessing it via adb/fastboot. I tried multiple drivers for my device, but no adb and no fastboot devices were ever found. The only thing that almost worked was booting phone into FASTBOOT mode by holding DOWN btn and plugging in a USB cable attached to PC. Once in FASTBOOT mode, My PC at least saw the ID for fastboot device. I tried to flash TWRP via fastboot, and it looked like it would happen, but in the end there was no phone screen response to my attempt, and the cmd window on my PC would get stuck and just hang.
Can someone please advise me on how I can fix this problem?

Back to official REC after flash TWRP 3.1.1 on RedMI 3S with MIUI 9.7.11.23 DEV

Dear Community,
I tried to flash TWRP 3.1.1 for Oreo rom with my Red Mi 3S. And I found some thing strange.
3S is flashed to MIUI 9.7.11.23 DEV. And BL is unlocked via XiaoMi's MiFlash_Unlock.
In Developer settings, OEM unlock is ON, and Lock status is unlocked.
Then I tried fastboot on my Mac to flash TWRP 3.1.1 in the Xperience Oreo ROM thread.
In the console after "fastboot flash recovery TWRP-3.1.1-0-unnoficial-oreo-v2-land.img", result showed OKAY. However, after a reboot, holding Volume+ and Power or "adb reboot recovery" will bring me to XiaoMi Recovery instead of TWRP.
I tried "fastboot boot TWRP-3.1.1-0-unnoficial-oreo-v2-land.img", and it works fine.
Anyone could help me to figure out why flash TWRP could not be done successfully?
Thanks much.

Have you tried rebooting the phone in recovery via the key combination( press all 3 buttons power+ vol up+ vol down and when you get vibration release power button and vol down but not vol up because i have faced similar issues while pressing vol up and power ) as far as i know after flashing a custom recovery you need to give the command " fastboot boot recovery.img" where recovery should be replaced by the file name of your recovery and adb reboot recovery is not working may be due to some other reasons but dont worry flash the twrp recovery via fastboot and then reboot using the above command

In this case, I think it means flash not successful right? using command fastboot boot twrp.img means only boot this time ...

Help!!! My Axon 7 is dead (Boot into fastboot and EDL only)

My phone was working fine, until it suddenly freeze and reboot. After that, it runs into bootloop at zte logo.
I had miflash the phone with stock rom. Flash successful, but the phone still bootloop at zte logo (can't enter system).
I can enter fastboot only (recovery + system => reboot);
try:
0. boot to system => definitely failed
1. hold volumn up + power button => failed
2. fastboot boot recovery => failed
3. fastboot boot twrp.img => failed
4. axon7tool -w recovery = successful , but failed when boot recovery
5. axon7toolkit : flash twrp = successful, but failed when boot recovery
6. miflash A2017 rom = successful, but failed when boot system + recovery
7. miflash A2017 rom = successful, but failed when boot system + recovery
:crying: I am desperate here.
Any help would be appreciate!! Thank you!

Try going into your recovery and formating as ext4. If you were using f2fs, edl won't work.

My edl is working, and miflash successful but then the device cant boot system (and cant boot recovery also)

First of all, redownload the stock EDL file. If you already have it, just check that it's not corrupted or anything. I'd advise redownloading it, which the files can be found from this thread.
Flash the stock EDL, then before booting, go into stock recovery (Hold volume up button whilst powering on). Do a factory reset, and also wipe cache. Now try booting. It should boot, and if it doesn't, then the only thing I can think of is either a corrupted EDL file or physical damage inside the phone to the memory chip.

I had miflash two different edl roms (china and us). And facing the same issue. It may be the hardware problem.

Everyone is telling you that you have to format your data partition, but you're not answering that: did you or did you not? If you have Fastboot, enter it and issue
fastboot format userdata
and hit enter

Stuck in fastboot after failed try to install lineageos for Redmi 7a

Newbie
I installed twrp on a Redmi 7A, I followed instruction to wipe the phone but at the moment to install the os image (which I am not even sure is working) I realised I copy the wrong file, so I poweredoff the pone to get the sd card to copy it and when I repowered I am stuck in fastmode.
sudo fastboot flash recovery recovery.img
sudo fastboot reboot
Keeps me in fast mode.
Is there anyway I can reboot with TWRP?

aside from the obvious power off then powering on pressing the power button and volume up, then releasing the power button when the phone starts, You might want to reflash via adb the boot.img and recovery.img you downloaded, to see those commands, go to this post:https://forum.xda-developers.com/redmi-7a/how-to/guide-twrp-root-magisk-custom-rom-t4027441

I tried every version arm and arm64 of 16 and 17 from https://sourceforge.net/projects/andyyan-gsi/files/
Attached is the logs if that helps recovery.log and dmesg.log

I sorted it by using this page https://forum.xda-developers.com/redmi-7a/development/rom-lineageos-17-1-t4056545
