[LG Nitro HD] mos6502:
Hello,

I have just rooted my LG Nitro with the Bin4ry root kit, followed a video tutorial. Can't post links because this is my first post on XDA Developers, unfortunately.

Everything seemed to work as expected.

Then I installed ROM Manager, and have proceeded with install instructions for CyanogenMod specific to my phone (I will post this after the end of my message as a reference since again, no links are possible).

In these instructions I began at "Installing a Custom Recovery Image" because the rooting instructions do not work for my phone (it has ICS installed, hence the need for the Bin4ry root method). I'm following the steps to the letter, and got stuck at "Boot into the ClockworkMod Recovery" - when I try doing this, SuperUser pops up and I grant permission to ROM Manager, and then it reboots - but instead of getting any option to install CyanogenMod, it hangs at the LG logo boot screen, with some command line-ish startup text along the top:

Secure booting Error!

Cause: boot certification verify

Enter the fastboot....

Enter the fastboot....

Long time no see!

-----

It will hang here until I hold down the button for 10 seconds or pull the battery. It will reboot normally afterwards though, thankfully. The phone is still working as-is so I'm not dead in the water, but my goal was to install CyanogenMod... is this still possible?

Thank you in advance.

-Owen

Installing a Custom Recovery Image

If the LG Nitro HD already has a custom Recovery Image installed, you may skip this section.

Search for ROM Manager in the Market (free or paid) and install the app.

Open the ROM Manager application and select Flash ClockworkMod Recovery.

Click on LG Nitro HD and then give the app root permission if it prompts you.

If it hangs after that and freezes up, just allow the app to Force Close. Then open it back up and repeat steps 2 & 3.

Once the flash was successful, you should see a dialog box that says "Successfully flashed ClockworkMod recovery!".

Press OK.

The ClockworkMod Recovery should now be installed on the LG Nitro HD.

Flashing CyanogenMod

If the LG Nitro HD has been rooted, unlocked, etc. through steps other than the method described above or running a custom ROM other than CyanogenMod and you are having issues flashing or booting CyanogenMod, it is recommended the LG Nitro HD be returned to stock & start over with the full instructions provided above.

Method via Recovery

Download the latest version of CyanogenMod.

Optional: Download the Google Apps for the device.

Place the CyanogenMod update.zip file on the root of the SD card.

Optional: Place the Google Apps .zip on the root of the SD card also.

Boot into the ClockworkMod Recovery.

Once the device boots into the ClockworkMod Recovery, use the side volume buttons to move around, and either the power button or the trackball to select.

Optional: Select backup and restore to create a backup of current installation on the LG Nitro HD.

Select the option to Wipe data/factory reset.

Then select the option to Wipe cache partition.

Select Install zip from sdcard.

Select Choose zip from sdcard.

Select the CyanogenMod update.zip.

Optional: Install the Google Apps by performing steps 7 - 9 again and choosing the Google Apps update.zip.

Once the installation has finished, select +++++Go Back+++++ to get back to the main menu, and select the Reboot system now option. The LG Nitro HD should now boot into CyanogenMod.

Method via ROM Manager

Launch RomManager.

Optional: Choose the first option in the app, Flash ClockworkMod Recovery to update to the latest version.

Select the Download ROM option from the main menu in the ROM Manager.

Select the CyanogenMod option, and then choose the latest version of CyanogenMod from the menu.

Optional: When you select the latest version of CyanogenMod, check the Google Apps option.

Once the ROM is finished downloading, it asks if you would like to Backup Existing ROM and Wipe Data and Cache.

If Superuser prompts for root permissions check to Remember and then Allow.

The LG Nitro HD will now reboot into the recovery, wipe data and cache, and then install CyanogenMod. When it's finished installing it will reboot into CyanogenMod.
