I recently tried to flash TWRP on my G300 and it failed, leaving me with no recovery for some reason.
So I tried to reinstall CWM with a pre packed file. It was a "command prompt" and popped up sent the file over to my phone and automatic rebooted it.
In the Prompt it had no errors and was all working fine.
But when rebooted it showed the Huawei logo and vibrated, the screen went blank and showed the logo and vibrated again.
Therefore trapping me in a boot loop :/
-Has a SD card that can connect to pc to transfer files if needed
-Has knowledge of ADB and Fastboot
-Can't get into recovery or bootloader just loops :/
