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.

Required Downloads
  • Nitro_Unbrick.zip (760.24MB) (Unzip to the location of your choice. 7zip is recommended.)

Notes Before You Start
  • Make sure to allow the phone to boot into the stock ROM at least once before flashing any other ROMs.

Unbrick the Phone
  1. Copy ‘Android’ folder to C:\
  2. In the ‘Run…’ dialog, type “sysdm.cpl” and press enter.
  3. Click the ‘Advanced’ tab.
  4. Click the ‘Environment Variables…’ button.
  5. In the ‘System Variables’ section, highlight the entry labeled ‘Path’.
  6. Click the ‘Edit…’ button at the bottom of the window.
  7. Add “;C:\Android” to the end of the Variable Value.
  8. Click ‘OK’.
  9. Click ‘OK’.
  10. Click ‘OK’.
  11. Log out of Windows and log back in.
  12. Once logged in, run the exe in the ‘LGP930’ folder to ensure that the Nitro drivers are installed. (This should install all of the necessary drivers. However, if it does not, install the drivers in the sub-folder as well.)
  13. Once drivers are installed, run the exe file in the ‘shttp3’ folder.
  14. Check the box to agree to the license.
  15. Click ‘Install’.
  16. When finished, run “C:\shttps\http.exe”.
  17. Right click the ‘Small Server’ icon in the System Tray and select ‘Settings…’.
  18. Click ‘HTTP’ at the top.
  19. Change the second box from ‘8080’ to ‘9002’ and click ‘OK’ in the top right.
  20. Extract the file named ‘www.zip’ located in the ‘shttp3’ folder to “C:\shttps\www”.
  21. Edit the ‘hosts’ file in “C:/Windows/System32/drivers/etc” and add the following line: “127.0.0.1 csmg.lgmobile.com”
  22. Save the file.
  23. In the ‘Run…’ dialog, type “ipconfig /flushdns”.
  24. Run the file named “B2CAppSetup.exe” located in the ‘KDZ_FW_UPD_EN’ folder and then close it.
  25. Run the file named “UpTestEX_mod2_marwin.exe” located in the ‘KDZ_FW_UPD_EN’ folder. (If you get errors, you may need to install msxml.msi.)
  26. In the ‘Merge’ section, click the folder next to the ‘Select model.dll’ field.
  27. Navigate to the “model.dll” file in the ‘KDZ_FW_UPD_EN’ folder and click ‘OK’.
  28. In the ‘Test’ section, change ‘PhoneMode’ to “EMERGENCY”.
  29. Click the folder next to the ‘Select kdz file’ field.
  30. Navigate to the “V10F_00.kdz” file in the root folder and click ‘OK’.
  31. Click ‘CSE web upgrade test’ at the bottom right of the window.
  32. With the phone off, hold the Volume Up button and plug it into the PC via USB.
  33. Once the screen says “Download Mode”, move on to the next step.
  34. Click ‘Upgrade Start’.
  35. Change the language to English and click ‘OK’.
  36. If the upgrade stops at 4%, start over from step 23 and try again.
  37. While the upgrade is in progress, copy the contents of the ‘Images’ folder to an SD card.
  38. When the phone reboots, use Task Manager to close the upgrade application.
  39. When the phone is up and running, tap the left button and choose English.
  40. Tap ‘Exit’.

Enable Root Rights
  1. Enable USB Debugging and Unknown Sources.
  2. Insert your SD card and let it mount and scan.
  3. Run the exe in the 'SuperOneClick' folder. (If you can't obtain root rights using this application, try Bin4ry's guides.)
  4. Follow the instruction given in the application.

Flash AT&T Stock ROM (2.3.5)
  1. Once the phone reboots, type “cmd” in the ‘Run…’ dialog and press enter.
  2. Type “adb shell” and press enter.
  3. Type “su” and press enter.
  4. Run the following commands one by one in order:
    Code:
    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/baseband.img of=/dev/block/mmcblk0p14
    dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
  5. After the last command finishes (It will take a while.), pull the battery out of your phone and unplug the USB.
  6. Replace the battery.
  7. Hold the Power and Volume Down buttons at the same time until the screen says “Factory Reset”.
  8. Press the Power button twice and wait for the phone to reboot into the stock AT&T ROM.

Install ClockWorkMod Recovery
  1. If you haven’t already, follow the steps to root once more.
  2. Install ROM Manager from the Play Store.
  3. Open ROM Manager and tap ‘Flash ClockWorkMod Recovery’.
  4. Tap the first option that says “LG P930”.
  5. Let ROM Manager do its thing.

Create A Recovery

  2. Hold the Power and Volume Down buttons at the same time until the screen says “Factory Reset”.
  3. Press the Power button twice and wait for the phone to reboot into ClockWorkMod.
  4. Tap ‘Backup and Restore’.
  5. Tap ‘Backup’.
  6. When the blue menu appears again, tap ‘Reboot System Now’.

  7. Tap ‘Backup and Restore’.
  8. Tap ‘Restore’.
  9. Choose your backup.
  10. When the blue menu appears again, tap ‘Reboot System Now’.

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.
