Since the device is pretty new and there is no other such guide for the Fino I decided to make one.
Flashing stock firmware on LG devices is universal (for the most part) so this guide will be pretty straight up.
This guide should be compatible with both the Dual Sim Fino and the regular one and all variants between them N/F/G etc.
I will try to make this as noob friendly as possible.
Flashing a stock ROM:
- Can unbrick the device (only if softbricked)
- Will remove root
- Can Wipe user data
- Can brick device (If done incorrectly)
STEP 1: Download and Install the LG DRIVER from here.
You might want to restart your computer after driver installation.
STEP 2: Download LG FLASH TOOL 2014 from here and extract it IN a NEW folder somewhere.
STEP 3: Download a KDZ firmware file from here
BE SURE YOU ARE DOWNLOADING THE RIGHT FIRMWARE FOR YOUR DEVICE (D290N, D295 and so on) OTHERWISE YOUR DEVICE MIGHT BECOME A HARD BRICK!!! LOOK FOR THE DEVICE MODEL BEHIND THE BATTERY!
STEP 5: Enter DOWNLOAD MODE on the device. You can do that by connecting a USB cable to the computer and then pressing and holding the VOLUME UP button while inserting the USB in to the phone.
STEP 6: Start LGFlashTool2014.exe. You should have something like this open:
STEP 7: In type ALLWAYS choose CDMA.
STEP 8: IN KDZ browse to the KDZ file you extracted earlier and select it.
STEP 9: Select Normal or CSE Flash
Normal Flash: Flash the ROM on top of the current one ( Good for updating firmware)
CSE Flash: Flash the ROM after WIPING EVERYTHING. (Good if testing new ROM or restoring a brick)
STEP 11: After that you will be yet again transferred to another screen like this:
Dont change or tick anything and just click OK
STEO 12: After that the process of FLASHING will begin.
THIS PROCESS CAN'T BE STOPPED SO BE SURE YOU HAVE EVERYTHING NEEDED TO WAIT FOR 5-20 MINUTES FOR IT TO COMPLETE.
DO NOT UNPLUG THE DEVICE UNTIL IT HAS FULLY BOOTED!
Do not worry if the program says disconnected or crashes at the end of the procedure. This is normal
STEP 13: Enjoy your reflashed device
By following this guide you agree that I TAKE NO RESPONSIBILITY FOR BRICKED OR DAMAGED DEVICES.
You and only you decided to follow these instructions.
