Hello
The first question is, does SM-A515F truly support Fastboot mode?
The second question is, can TWRP be flashed on this phone using Fastboot commands (if this exists)?
Yes, one can enter fastboot mode on SM-A515F, but it cannot be used for flashing anything

Basically, my xoom has been rooted and currently I have CynogenMod9 RC0 Wingray currently installed.
I wanted to install a new rom but I couldn't do this using CWM Recovery as the SD Card doesn't Mount. Upon doing some reading I found I need to install the Rogue (or EOS) Recovery image. This is where my problems begin as I can connect to the device when the xoom is fully booted in the CM9 and connected via debugging mode(running adb devices returns a sequence of numbers ).
But then when I reboot into the bootloader it gets stuck on "Starting Fastboot protocol support." and i can't connect via adb!!!
I believe this started happening after I unlocked the bootloader but i can't be 100% sure (fastboot oemunlock)
Please help!!!
When it is on fastboot mode you can only use fastboot commands (fastboot flash recovery recovery.img) that is how you would install the recovery image from rogue or EOS or TWRP, whichever you choose.
Or to make it easier, you can boot your tablet, install GOO Manager. When you open the GOO manager, tap the setting in the top right corner and choose Install Open Recovery script and let it install TWRP. Then boot to recovery.

You specifically said it says starting fastboot protocol. That's as far as it goes. You then issue fastboot commands, not adb commands

Ohh ok, makes sense. I will give it a try later when i'm home. Is there a Fastboot command i can use to check the device is connected??

Hi,
Device is: Asus Zenfone 2, Z008
At some point I managed to brick it. Restored it using xFstk and some fastboot magic.
Now, the big issue is, I cannot boot to recovery.
I can load bootloader (do fastboot commands), chose "Recovery", but it will just boot normal into the OS. Droid with hazard doesn't appear, just normal boot.
Tried (not all at once)
fastboot erase cache
fastboot format cache
installing twrp
flashing stock recovery.img
No joy.
What am I missing?

Hi !
A quick answer has been provided here https://forum.xda-developers.com/showpost.php?p=71063211&postcount=598
Try this command after placing this recovery img into the adb folder and boot into bootloader
fastboot devices
enter
(check if it is recognised) then
fastboot boot recovery.img
( where recovery.img should be the exact name of your recovery you want to boot into)
Keep an eye on that thread you already have posted , more users may have replied
Good luck !
whenever i try to go into recovery mode, it takes me to the default one even after i flashed twrp. my bootloader is unlocked and i flashed twrp several times. even when i use the command prompt from fastboot mode it still takes me to the default recovery. any ideas to what's wrong?

This could be a solution or a workaround:
"Hello i just had a personal experience with my Asus zenfone selfie Z00T Stock recovery kept replacing TWRP. (Boot loader already unlocked)
This is how i got around it i downloaded the latest TWRP for my device and placed directly in minimal adb and fastboot app folder then i renamed it to recovery .
then i put my device in fastboot mode using the buttons on the phone and After i ran minimal adb and fastboot app as admin then i typed fastboot flash recovery recovery.img
once done i then i typed fastboot boot recovery.img. and my phone booted to twrp recovery then i selected reboot recovery directly on my phone and to finish reboot system (still in twrp) that's it.
(OEM commands to boot from fastboot to recovery do not work on some devices )
it only worked for me eventually because i downloaded the latest TWRP from the official TWRP website.
The idea is to flash the custom recovery and then booting from the custom recovery.img that you just used to flash (the one still on the pc) using minimal adb and fastboot app.
IT may not work on all devices as the commands may change from one device to another but the idea stays the same. (example for nexus fastboot -c "lge.kcal=0|0|0|x" boot recovery.img)
I hope this will help some people out."

Okay, I was a bit too early with that. The next time I turned off the phone and tried booting to recovery (Vol up+pwr), I got booted into factory recovery (mi-recovery 3.0) :/

Try this:
when you are in fastboot mode type:
Code:
fastboot boot recovery.img
This command will boot your phone to twrp. Install twrp .zip file (there are 2 options when installing .img or .zip)
after this go to ADB/Sideload - This is in Advanced section
Then swipe to start a sideload. Now on your pc type:
Code:
adb sideload recovery.zip
This worked for me. I hope this works for you too
