Unrooting and restoring Burst to stock

*You will need both Stock ROM and Stock Recovery to apply OTA update when/if they are released
**Restoring these will most likely wipe your data so be sure to backup first!!!

Restore stock ROM with CWM
1-Download one of the following zipped backup: (original firmware) (1st stock update) (2nd stock update, newest)
2-extract zip to the "/sdcard/external_sd/clockworkmod/backup/"*
3-If you have CWM installed on phone, boot into CWM and skip to step 7*
4-If you don't have CWM installed, Download cwm- and save it to “C:\Program Files (x86)\Android\android-sdk\platform-tools”
5-open your command line and navigate it to “C:\Program Files (x86)\Android\android-sdk\platform-tools” folder
6-Run the following commands
adb reboot bootloader
fastboot boot cwm-
7-backup and restore > restore > select backup to restore > Yes – Restore
8-You may need to do a “wipe data/factory reset”, “wipe cache partition”, and Wipe Dalvik Cache” to get OTA updates that AT&T/Pantech push out.
9-reboot system now

Stock recovery
*Recovering to Stock ROM via CWM does not restore Stock recovery. Here is how to restore Stock Recovery.
1-Download recovery.img and save it to “C:\Program Files (x86)\Android\android-sdk\platform-tools”
2-Now open your command line and navigate it to “C:\Program Files (x86)\Android\android-sdk\platform-tools” folder
3-Run the following command
adb reboot bootloader
4-When the bootloader screen shows up on your phone then wait a few seconds to make sure your phone is recognized by the computer then run the following commands
fastboot flash recovery recovery.img
fastboot reboot
Alternative method for stock JUUS03122012 and Recovery:
1-Download PANTECH_PRESTO_BIN_JUUS03122012.pdl
2-Download and extract it
3-Boot phone into Emergency Download Mode - With device off, press and hold power + Volume Up + Volume Down
4-Execute P9070_Download.exe
5-Select “Open File” and select the PANTECH_PRESTO_BIN_JUUS03122012.pdl file
6-Select “Reload File”
7-Select Download
8-Just select the default location for the XML log file
*I had to do this twice as it failed the first time and the second time it was successfull
