This guide is based on information found in leejames55 HBOOT loop thread and torxx tutorial, I just wanted to make thing clear, simple and consolidate all information in one place for non-dev users. So thanks to them and everyone who contributed.
After seeing alot of people having problem after flashing a rom, restoring RUU, re-locking bootloader, I've decided to make this guide in order to help everyone. If you follow this guide there's a good chance that you will manage to recover your phone
This is for people who have the following problem:
Cannot boot into ROM (e.g Stuck at the HTC Logo)
Re-locked bootloader while having a non-working ROM
Cannot flash RUU because battery is below 30% - IMPORTANT: You must flash the new version of ClockWorkMod in order to be able to recharge the phone while off and from recovery
The most common problem is being stuck at the HTC Logo after flashing a ROM, try clearing the fastboot cache with these steps:
Power off your phone and hold the power button + volume down
Choose fastboot from bootloader
Connect the phone to your computer
On computer type:
fastboot erase cache
Choose "Reboot" in fastboot menu
If this doesn't work, try the rest of the guide
If you cannot flash RUU, go into recovery etc. because battery is below 30%
IMPORTANT: You must flash the new version of ClockWorkMod in order to be able to recharge the phone while off and from recovery. So, flash the new recovery and this problem will NOT happen.

But there is no explanation on how to to solve the problem. All the suggestions are good only when you have at least 20% battery.
So here I want to share on how I solve my problem to get the battery up to at least 20% so that you can fastboot flash anything, but to run RUU you need to have more than 30%. This works for me and hopefully it will work for others too.
Instead of plug in and plug out the usb cable to and from your phone when connected to PC (which actually not working for me), what I did was :
1) connect the phone to PC, your phone will boot into bootloader with red light flashing on and off or all the way red or no light at all.
2) use the vol button to scroll to power down and press power to off.
3) if the phone boot again to bootloader, repeat (2)
4) if the phone not booting, press the power button to on the phone, it will boot to bootloader again. Try the fastboot flash ** (whatever you want to do, either flash unlock.bin to unlock bootloader to flash CWM recovery or relock bootloader and flash stock recovery). If it fails due to low battery, repeat again (2) then (3) and (4). I did this less than ten times to have fastboot flash working.
What I notice is whenever we press power on, it will go to splash screen but unable to pass the bootanimation due to lack of battery, it will go back to bootloader. In the process, the battery get charging but stop when we are in bootloader. So restart again & again (power down in bootloader & power on again) will charge the battery until you have enough juice for fastboot flash.
Note: item (4), I did the fastboot flash ** before power on, it will say "waiting for device", once the phone is on and in fastboot mode, the command will runs. So once the battery reach about 20%, it will runs succesfully.
