How to Unbrick, Root, And Install CWM

Disclaimer: This guide is for your information only. I am not responsible for any further damage cause to your device by not following the guide correctly. Parts of this guide are based on the Unbricking guide produced by XDA member, Machzelet. Namely the Unbrick process.

This guide will give you step by step instructions on how to initially unbrick, root, and install ClockWorkMod Recovery on your LG Nitro HD. You will also learn how to make yourself a CWM backup that you can use to unbrick your Nitro whenever you need to... even when you are away from your PC.

NOTE: More people have had success using this guide on Windows XP than Windows 7.

It is understood by the author that CWM and CWM backups are nothing new to the XDA community. This guide is less about groundbreaking discoveries and more about clarification and introduction of an on-the-fly unbricking concept. As with all posts on the community forum, this guide is not set in stone and can/will be changed upon suggestion from other XDA Forum members.

No, this will take you into the Korean version. It is essentially the same as Machzelet's guide. I just clarified a few of the steps, added a different rooting method, and explained ClockWorkMod Recovery installation and backup/restore.

great guide, nice write up.

just to be sure, under restoring your backup after bricking #5. says to factory reset, then restore you CWM backup. Will your clockwork backups be deleted when you wipe data/factory reset, I think they usually are on my galaxy tab 7.0 plus.

thanks.

Download this file and copy it to your SD card.

Try replacing "dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13" in step 3 of the AT&T ROM section with "dd if=/sdcard/recovery-clockwork-5.8.2.0-p930.img of=/dev/block/mmcblk0p13" and go through the steps again and ignore the ClockWorkMod Recovery install section.

Edit the ‘hosts’ file in “C:/Windows/System32/drivers/etc” and add the following line: “127.0.0.1 csmg.lgmobile.com”

Thank you for responding scott0. I have been busy today and not able to read the latest posts.

Also, I had a lot of troubles with that part too. So I added step 23 to refresh the DNS.

That *should* work. but, I've never had luck with just having a single space. It has only worked for me when i use a tab.

Also, do you still have the B2CAppSetup.exe application running?

Can we UN-sticky the "Official" guide and make this one the official? That OP did some great work, but won't update the steps to help people avoid common problems (ie. rename the kdz file). If people started using this one instead, it would be more beneficial to the community.

I tried to download this. but it told me 12 hours to download. wtf?

It's probably a big file because it contains 2 complete ROMS, plus other files.

    That would be sweet. A jtag will cost me $80 plus shipping. My phone will not power on. Not even the buttons at the bottom light up. When I connect to a Windows 7 PC via USB (I have the proper LG drivers installed), the notification bubble in my system tray says: QHUSB_DLOAD instead of the LG Driver name you get after installation. I flashed a JB 4.1.2 custom ROM AND kernel clearly marked for another phone (i9100), and after a restart, I get a black screen. Bricked. Any help would be appreciated.

    This guide won't be useful unless you can get to download mode.

    So is this a way to get back to stock from ics leak? Or would I still need to unbrick into the korean version?

    Sent from my LG-P930 using xda app-developers app

    No, this will take you into the Korean version. It is essentially the same as Machzelet's guide. I just clarified a few of the steps, added a different rooting method, and explained ClockWorkMod Recovery installation and backup/restore.

    Yes I am I try:
    CDMA-Emergency
    I try all possible combinations

    All I can recommend is trying the emergency mode with att firmware. When I was having trouble, this was the only firmware that would boot on my phone.
