I have installed both ADB and Fastboot with all the drivers on both a windows computer as well as a Mac just to be sure it wasn't me. I recently followed the guide to unlocking the bootloader to the vzn note 4 and on download mode I am showing developer. All is well aside from when I need to flash the TWRP recover, I tried flashing through Odin and it states complete and the phone reboots. When rebooting to recover, stock android recovery opens. I would like to know if flashing through Fastboot would work being that it is unlocked. If so the only issue is, ADB is working find but Fastboot will not detect the phone at all when it is put in download mode. Any ideas?

Hey. I was using a 5.0.1 GPE Rom on my M8 and decided to update both the firmware and the rom to 5.1
I Backed everything up and decided to, as usual, use adb to sideload the firmware to the phone. I did and everything went as expected. After I finished I rebooted to android. I get NFC service stopped working, System UI stopped working and I can't interact with the phone. My thought, well let's go to the recovery and flash a rom I have in my external SD card. No recovery to be found just a android guy belly up with a red ! sign on his belly.
So I thought, I lost my recovery due to the firmware flash, I had happened before, So i went online found a TWRP recovery and went to flash it. Reboot to fastboot USB mode, but then in adb I cannot see the device at all. "adb devices" shows and empty list. I tried my windows 7 laptop to the same result.
Can anyone PLEASE PLEASE help me, I'm kinda freaking out at this point and am running out of options

When in fastboot mode - run command fastboot devices
No adb when in fastboot mode
To flash a recovery (unlocked bootloader)

Sometimes some outside thought can be just ridiculasly helpfull when you are stuck in a tiny issue.
Thank you so much Kind sir, my heart rate thanks you aswell.
What a silly mistake
I have an HTC One m8 that is stuck on Bootloader. It is an unlocked bootloader with S-Off. I had CWM but I installed stock recovery back onto the phone before flashing a stock kernel (I was trying to make the phone look untampered with before I turned it over to my provider), the Kernel came with a sha1 and was from a trusted website and I am 100% sure it was the right compatible Kernel I'm pretty sure I just had a bad flash.
I have tired the following to get the phone past the bootloader:
1. Fastboot USB Mode --> Try to get ADB to recognize the device --> Debugging mode isn't on (obviously) --> ADB can't recognize the device.
2. Use AndroidSDKSlim/ Android SDK tools / Android Utility to remotely turn on Debugging mode (I got nowhere with this)
3. Attempted to use PdaNet to remotely turn on Debugging mode (got nowhere)
4. HTC Sense doesn't even know whats going on
I just need to get TWRP or CWM or litearlly Any recovery installed. That's all I need, I can do everything from there. I can't remotely install a recovery via adb because adb can't recognize my device because I can't turn Debugging mode on because my device is softbricked!!! Gahhhh. I haven't been able to come up with a way to remotely enable debugging mode or to get adb to recognize my device.
Any ideas/comments/suggestions would be heavily appreciated - I've resourced from every relevant thread I could find. Posting here was a last resort I try to fix things on my own but I'm too many days into this with no results please anybody.
ADB won't work while on fastboot mode. ADB only while in recovery or on OS running.
You don't need USB debugging on for fastboot
fastboot devices - see whether your device is listed with serial no.
if yes then run
fastboot flash recovery NameofRecovery.img

Thank you for reply!
I have not been able to get ADB to recognize the device, which is pretty much my whole issue right now. It does not appear under the devices list. If I can just get adb talking with my phone everything else should be easy, I just can't figure out why it's not recognizing it.

When on bootloader/fastboot mode
run command
fastboot devices
not adb devices

Oh.. My..God..
You just saved my life, this whole time I thought fastboot utility in AndroidSDK was just a stripped version of ADB. I'm a moron!
I have TWRP up and running holy crap thank you so so so so much, you are seriously a life saver.

1) Reboot the phone using Power+Vol Up
2) The moment the screen goes dark to reboot and before the white HTC logo screen appears again (Should be around 10 seconds), press the volume down key.... Do not let go of vol down until you see the bootloader screen
3) If the bootloader doesn't appear, you either started pressing Vol Down too late, or let go of it too early. Just do the steps again until you get it right.
4) Once you are in the bootlader, select select fastboot by pressing power key.
5)you can flash either permanent or temporary a TWRP recovery once you are in fastboot.
6)Once you are in recovery mode, you can transfer any custom rom to memory or sd card, then install it from the place you chose.
7) you can flash RUU file at fatboot mode as well.
I've been trying to flash TWRP recovery to my rooted LG G3 D855 (running 4.4.2 KitKat). I used the "Bump" method (thread) since I don't have an unlocked bootloader.
I tried the ADB method in that thread, I tried the Flashify method, and I tried the Official TWRP App. Each time, the recovery flashed correctly. But when I attempted to reboot into recovery (using the method in the linked thread, or in the case of the apps, they prompted me to reboot into recovery), my phone didn't bring up TWRP recovery or even the stock recovery. It just brings up "fastboot mode started". It's not stuck though, it boots normally when I pull the battery and power on.
I also separately tried rebooting it into fastboot mode with it plugged into my computer. When I entered "adb devices" into the command prompt, the device came up. Then I rebooted it into fastboot mode and entered "fastboot devices" - then nothing came up. I entered some other fastboot commands and it said "< waiting for device >". So it appears I can't issue normal fastboot commands either.
Any thoughts on how I can succesfully flash TWRP? Thanks.
i have installed my TWRP via this app -- https://ulozto.sk/!lisJevpDG1oS/recovery-d722l-apk
try hope itll help you
Well, somehow you failed to install it. Upgrade to LP (preferably v21C) and try this
I can get my Zenfone 2 up to the fastboot screen, but no further.
Under PC device manager is shows "Android-Phone" as the device, but no drivers loaded.
I've tried a few different drivers, but even though they seem to install OK, "Android-Phone" (in device manager) still won't show as having a driver.
Some threads say I have to enable Android Debugging, but how to do that when the ONLY screen I can get on the phone is fastboot??
Help???
Boowho??
You can try this.
1. Uninstall all drivers for phone you installed on PC, then reboot.
2. Disable antivirus on PC then install standard Intel android device usb drivers. You can download them from Asus website. Then reboot again.
3. Connect phone to PC in fastboot mode.
4. In the device manager you should see "Asus android device" under which "Asus android bootloader interface".
5. Check connectivity in minimal adb & fastboot software (you can get it from XDA) by command "fastboot devices" without quotes. It should answer "some number<space>fastboot".
If all is ok then you can flash raw stock firmware in fastboot mode & update it to latest version OR unlock bootloader, flash TWRP & install custom rom.
Thank you Sanesh. I got all the img/bin files successful now. However, the ZF2 has this issue when you select recovery from bootloader screen it gives dead android. You can then (extra step) hold power and VOl + and get into stock recovery. This is a flaw in the original firmware, I think.
BUT, this extra step is causing TWRP not to be entered. Stock recovery is OK, but not TWRP.
I had to recover the phone using the SOC drivers; before that TWRP worked perfectly.
Thanks
Have you unlocked bootloader ? Unlock bootloader first then flash twrp using giovix92 method. Then reboot to recovery.
Thanks. Turned out I was using a twrp image that is only for marshmallow. I still use lollipop. Every thing is now back to where it was before I had to recover the thing using the SOC method.
Lesson learned. un-root before trying to upgrade to MM.
I flashed a firmware less miui 10 with twrp. It was ok but the camera was not working. I went to custom recovery but saw that twrp was overwritten by mi-recovery. I thought of loading twrp through fastboot but my device is not listed in adb devices. What to do? Please help.
The option to change to MTP is not showing. The phone is simply charging. I tried turning usb debugging on and off and installing wpdmtp.inf but no help.
If your computer has drivers installed, it may be a problem with your phone system.
Is your bootloader unlocked?
If unlocked, power off your phone. Then hold POWER and VOLUME(-) for about 11 seconds to enter fastboot mode.
You can flash dummy.img first to temporary bypass ARB.
And then you can flash twrp recovery.
Use twrp to backup all your needed data.
Because of the ARB, do flashing by recovery is not recommended.
You can download MiFlash to do a clean flash.(Don't lock the bootloader)
