Will be translating the content and tools later on and update this post.
When to use:
When you want to go back to stock
When your phone is in a miserable software state that it can't even boot to recovery.
Warnings:
DO NOT USE THIS ON THE OnePlus One
THIS WILL ERASE ALL EXISTING DATA ON YOUR PHONE, EVEN THE eMMC
Instructions:
Connect your phone to the computer, making sure all the drivers are installed.
Enter fastboot by pressing the Volume Up + Power Button
Unzip the unlock.zip package to a folder and then run FastBootXXXXOS.bat
Your system should be able to bypass any bootloops/problems and enter the OS, during this time it is recommended to backup all your important data and prepare for the next few steps.
Re-enter fastboot mode, we will now begin to reflash the system flash memory, which will erase everything.
Connect your phone to the PC if not already connected, then go to Device Manager and check whether or not a device named QHSUSB_BULK APPEARS like below:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It should say that it doesn't have any drivers installed. So inside the archive there should be a inf driver file, to install it right click on the device > Update Driver Software > Browse My Computer for driver software > click on inf file.
The driver should be installed now.
Using the QCom Download tool you should now be able to see the device appear in one of the slots. Just press start and it should start flashing! And when it finishes it should be good as new!
