Now you have everything you need, let’s begin fixing your bricked LG Nitro HD.
How to Flash and Return your LG Nitro to stock SU-640 Rom:
- Put your LG Nitro HD in download mode: http://www.lg-phones.org/lg-nitro-hd-download-mode.html
- Open up UpTestEX_mod2_marwin.
- Hit the folder icon next to the "Select kdz file" line and browse to the SU-640 v10f_00.kdz
- Select "CSE web upgrade test", a new window with some options including an "Upgrade Start" button should appear.
- Take a deep breath…there’s no going back. Press "Upgrade Start".
- At this point in time another dialog box will appear asking what country and language the LG Mobile Upgrade tool should use. Since this guide is written in English, I assume you’ll want to change it from Republic of Korea to All other countries and Korean to English. This affects the language that output messages are displayed in in the LG Update tool only, it doesn’t affect anything with the rom (that’ll be all Korean on initial startup lol).
- The update tool will proceed to flash your phone, but it should never complete "normally" (mine never made it past 4% according to the tool and other users have reported similar behavior). However, your phone should reboot once or a couple of times and then just be sitting idle waiting for you to go through the setup wizard. At this point, just kill the LG update tool process in task manager, don’t wait for it to complete because it won’t.
For people who are to root your LG Nitro HD, go here:
Restoring LG Nitro HD partition images:
- Open up a command prompt and navigate to the folder you saved your recovery images to (hopefully you put them in the same folder, it’ll make your job easier)
- Push all the image files to the phone’s sdcard using the command:
- adb push filename.img /sdcard
- Now the real fun begins! Use the following commands:
- adb shell
- dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8
- dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13
- dd if=/sdcard/firmware.img of=/dev/block/mmcblk0p1
- dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
- dd if=/sdcard/baseband.img of=/dev/block/mmcblk0p14
- You won’t be able to issue a reboot command, so just hold power down on your phone til it’s off and hold the volume down button so that it comes back up in factory data reset mode. You will want to pull your sdcard at this time if you don’t want your data erased.
- Hit power twice and your LG Nitro HD should go through its reset process and (hopefully!) come back up in a working (and rooted) AT&T "stock" rom
