[Q] ADB working, Fastboot not

Good day all, I am a NOOB first of all and apologize if this is not the correct forum to be posting this in.
I have a Colors Mobile X120Q and a Colors Mobile X100 mobile phone. Both devices are rooted and are working with ADB commands. If I try to boot into fastboot however the units will reboot into normal mode after issuing an ADB reboot bootloader command. I am able to boot the device with a combination of vol+ and the power button which boots the devices into a recovery screen that has a green droid with a red exclamation mark but when the devices are plugged into my PC (Win 7 64x) there is no USB detection. I have the drivers installed and have updated ADB and fastboot.
My question is can the OEM lock the recovery boot on the device so that it is not accessible from ADB? If so is there a way to access it so I can use fastboot?
Thanks for the help in advance!

[Completed] Softwinner V90 tablet stuck in bootloop after adb reboot bootloader.

Hi
As a noob I thought I would backup my system on my A33 softwinner V90 chinese tablet.
It has a stock rom and is not rooted.
I downloaded SDK and had troubles with the device no being reconised ADB devices.
I downloaed adb V1.3 and installed it into platform-tools.
ADB then worked. backed up the full system.
After more reaserch I booted into recovery to see if i had one. Exdroid.
I thought I would see the bootloader screen so I used ADB boot bootloader command.
The tablet booted to the first Android screen and nothing. I have tried avrioud key resetts but I take it that it is in bootloop.
Just the first android screen shows.
I also can not seem to load fastboot drivers. ADB drivers load when I connect the drvice but I have no option to load fastboot drivers.
How do I get out of bootloop or into recovery mode.
Regards
RDF.

[Completed] Fastboot into Recovery Mode not working Nexus 5 CM-13.0

I downloaded the CM update as always and the first time I used the option to update via the CM updater it bricked my phone! COME ON!
Now I can't access y device via adb, fastboot or anyway. I get a blank screen when I select Recovery Mode and when I power on normally.
Adb recognizes the phone but says it's "unauthorized" and won't allow me to do anything. As far as I know the phone is on USB debugging, but I can't check now cause I can't access the phone.... It's also unlocked and rooted and I have never had problems with this when I flashed a zip file or used abd before.
If I try to unlock it via fastboot I get "error" or the eternal "waiting for device". Same as when I try to flash a recovery image.
Please help! I'd like to get my phone back...
Thank you!
