After days searching for a way to enter in CRM after a bad flash bios update... I've finally found how to recover my LG R500-CP01P1 from brick! And I did it with a generic pendrive/usb flash disc!! Ok let's see the steps. 1- First create a crisis recovery disk - You will find many resources on how to do it in this same forum. 2- Shut down your Notebook 3- No need to unplug power or remove batteries, you can do it if you wish. 4- With the notebook turned off, press the Power Button and hold until it turns on and off. This will set a flag to bios boot eneble CRM on the next POWER UP! When you do it, make sure the pendrive is already on any USB ports. Should work as it did for me. Hope this post helps anyone, LG doesn't.
