[Completed] Cannot enter fastboot after flashing recovery.

I flashed a CWM recovery on my Micromax Q380 (Canvas Spark) phone. After that only logo appears and it reboots again and again (boot loop). I tried entering into recovery and fastboot (Vol UP + Pow and Vol Down + Pow respectively) but cannot.
ADB is not able to connect and I cannot remove battery. After battery drained out as soon as I plug in USB cable to connect it to laptop, it start charging and boot loop starts again. What can I do now? Is there any other way to flash stock recovery??

[Completed] Huawei G8 TWRP not overriding EMUI revovery

Phone: Huawei G8 Single Sim (Vodaphone carrier)
after installing the unofficial cyanogen mod ROM and installing TWRP for my device, when holding down the power button & also trying through fastboot, i always seem to go to the EMUI recovery and not the TWRP one.
I have tried the following.
>using power button and volume up
>booting into recovery through fastboot (also trying this straight after flashing)
My phone is unlocked and rooted i have also tried flashing through the twrp app and flashify but get an error along the lines of failed to copy files.
The only way i have been able to get into twrp us by using the command "fastboot flash boot twrp.img" which then boots the phone into twrp.
Any help would be much appreciated.

[Completed] inFocus m810 stuck in bootloop no recovery no fastboot

Hi guys,
I own an InFocus m810 and had flashed a marshmallow based rom. It was all working fine until after 6 months my phone started to hang a lot so I decided to factory reset it... I tried to go to twrp but it wasn't going to recovery mode like it used to (by holding power and volume up buttons together) so I downloaded quick boot from play store and booted into recovery there I wiped my dalvik cache and all the files then I flashed supersu zip and rebooted but it's still stuck on the boot screen. I tried to go to recovery mode by trying all the combinations (vol up+ power, vol down+power,etc) but in vain... I even tried to flash my stock rom again by going to fast boot mode but it isn't even going to fast boot mode so that my pc can recognize it but it doesn't work.. when I press vol up+power(combination for recovery mode) it restarts and again go to boot logo and get stickers there... I looked over entire internet but everywhere it's telling to flash rom or wipe cache etc... but I can't even go to recovery and fast boot to wipe cache or flash rom please help me thanks..
