Procedure

Flash a Nexus 4 Partition Table with LGNPST

1. Backup all important files
2. Install LGNPST(if you dont have it already)
3. Extract the zip file
4. There should be a file with a file extension(.tot)
5. Change the file extension to a .bin
6. Start LGNPST
7. Put your phone into download mode (Turn it off and press the Volume Up + Volume Down buttons, a picture will pop up saying that the phone is in download mode)
8. Plug your phone into your computer(Make sure you are using the usb cable that came with the phone)
9. Wait until your phone is recognized by the computer
10. Open LGNPST
11. Next to the picture of a phone with "Emergency" on it there should be a place where you select the DLL file
12. Click on it and select the one that says LG_E970(If you don't see it choose LG_LS970)
13. Under the DLL file selection there should be a BIN FILE selector
14. Choose the bin file you renamed earlier
15. Start the flashing procces
16. Wait until it is at 85%

Install External SDCard Support

(only known to work well on 4.2)

Increase 8GB to 16GB Storage

The partition table we flashed was made for the 8GB Nexus 4, since we wanted to stay on the safe side. To reclaim that lost space, we have to expand the partitions to fill the rest of the free space on the internal storage.

Files Needed

• Modified DD
• 16G Primary GPT
• 16G Secondary GPT

Directions

1. Get all the required files above and adb/fastboot if you don't already

2. Get a microSD card and put the downloaded files in it

3. Get Sk8's CWMTouch Recovery here. This has SDCard support

4. Flash the recovery

5. Boot into the recovery

6. Backup your files on your sdcard

7. Connect your phone to your computer and type

    adb shell
   

8. Once in shell, type(REMOVE THE #)

    # cp /external_sd/dd / 
    # chmod 755 /dd
   

9. Backup your existing partitions(REMOVE THE # AND MAKE SURE YOU TYPE / BEFORE dd)

    # /dd if=/dev/block/mmcblk0 of=/external_sd/pgpt8G.img bs=512 count=34
    # /dd if=/dev/block/mmcblk0 of=/external_sd/sgpt8G.img bs=512 skip=30777311
   

10. Move content of DDR and grow partitions to their new locations(REMOVE THE # AND MAKE SURE YOU TYPE / BEFORE dd)

    # /dd if=/dev/block/mmcblk0 of=/external_sd/DDR bs=512 skip=15267840 count=2015
    # /dd if=/external_sd/DDR of=/dev/block/mmcblk0 bs=512 seek=30775296 conv=notrunc
    

11. Install new partition tables

    # /dd if=/external_sd/sgpt16G.img of=/dev/block/mmcblk0 bs=512 seek=30777311 conv=notrunc
    # /dd if=/external_sd/pgpt16G.img of=/dev/block/mmcblk0 bs=512 seek=0 conv=notrunc
    

12. Type parted /dev/block/mmcblk0

13. Parted should start up and show you this:

     GNU Parted 1.8.8.1.179-aef3
     Using /dev/block/mmcblk0
     Welcome to GNU Parted! Type 'help' to view a list of commands.
     (parted)
    

14. Type "p" (without both "s) and press enter

15. It might take a few seconds but you should see (if you see a major difference then skip down to the end and look at the bullet point)

16. Reboot your phone into the bootloader(type the command below and then immediately press the Volume Down button,if that doesn't work press the Volume Up button instead)

      # reboot
    

17. Now you need to factory reset

    fastboot erase userdata fastboot -w

18. Now press the power button and it should start booting!

• In case parted reported an error, put the old 8G partition tables back. This should not happen but it may happen

  /dd if=/external_sd/sgpt8G.img of=/dev/block/mmcblk0 bs=512 seek=30777311 conv=notrunc
  /dd if=/external_sd/pgpt8G.img of=/dev/block/mmcblk0 bs=512 seek=0 conv=notrunc
