Simplified UNROOT and return to STOCK procedure
1) Download recovery.zip and update.zip
- UNZIP recovery.zip to top level of /sdcard (overwrite files if necessary) [link]
- COPY (do NOT unzip) update.zip in top level of /sdcard [mirror 1] [mirror 2] [MD5: 2db9b55305cff37a6b6e402fb8518acf] [Size: 88,007,618]
- Turn OFF USB Storage Mode when you are done, if you used it to copy update.zip to sdcard
2) Install stock recovery
- SKIP if you already have stock recovery
- SHORTCUT (optional) if you have Xionia CWMA Recovery, as a shortcut, skip this step, turn OFF signature verification, and perform Step #3 TWICE.
- from "adb shell" or "terminal" (do not type the $ and # symbols)
3) Run ZVD update.zip
- press [Vol Dwn] button once to highlight "apply sdcard:update.zip" [pic]
- press the [Menu] button to run the ZVD updater [pic]
- after around 75 seconds (based on class 6 sdcard) it will return to the recovery menu [pic]
- press the [Menu] button to continue the rest of the install (write the radio, boot android, recreate dalvik-cache). [pic]
- after 3-7 minutes you should be booted into Android
Note #1: After 7 minutes, if your phone is still stuck at the Android logo, perform this procedure.
Note #2: If for some reason you need to re-root: ZVD [GingerSnap] [GingerBreak]
4) Reboot to recovery
- unplug usb cable, power down, wait until ALL lights are off, simultaneously press and hold [Power] [Vol Dwn] [Home] until Recovery shows up, release buttons
5) Wipe your data
- press [Vol Dwn] TWICE to highlight "wipe data/factory reset" [pic]
- press [Menu] to select
- press [Vol Dwn] SEVEN times to highlight "Yes -- delete all user data" [pic]
- press [Menu] to select
Note: If you want to scrub even your Sprint data login information and phone # from NVRAM, for example if you were to transfer/sell the phone to someone else, perform a ##786# reset from the dialer in Android (you'll need your MSL/SPC/Service Code - ask Sprint or use CDMA WS) Make sure you have the stock recovery properly installed (step 2) before you do this or you *may* brick your phone. It is worded to sound dangerous just so you pay attention. Xionia recovery 12518.6 and higher does not have brick issue.
Reference:
- Full ZVD update.zip (works from any version)
- Revert to V9 using KP500
