USB Update

The steps to access recovery mode are listed in the "Recovery Menu" section above. Also, a list of OTA sony downloads can be found Here

In recovery mode, any USB storage device will be automounted when inserted. If it's inserted at the start of recovery mode, the device will attempt to do a USB update. This executes the following:

cmd:ls /tmp/mnt/diskb1/package_list_*.zip | head -1 | grep "package_list_"
cmd:/bin/sony/check_version.sh /tmp/mnt/diskb1/package_list_0.zip

For a USB update to succeed, the following are necessary (but not sufficient):

  1. there must be a file matching /package_list_*.zip or else you get the error "find package error: no such a package !"
  2. the zip must contain a file "system/build.prop" or else you get the error "caution: filename not matched: system/build.prop"
  3. the zip must contain a file matching "package_list_*.txt" or else you get the error "caution: filename not matched: package_list_*.txt"
  4. The system/build.prop must have an ro.build.id that is greater than the current values. Otherwise you get an onscreen message saying "USB data is old".
  5. At this point, the signature is checked:
                            
package update start !                                                          
cmd:/package_update.sh -y -l 0 -p /tmp/mnt/diskb1/package_list_ogm_2.1_2011_asu1

Verifying..                                                                     
Error in main(47):Footer Error                                                  
Signing Verify Error                                                            
Error!!        

If a valid-looking zipfile on a USB storage device is plugged in when the system goes through a normal boot, it will abort and reboot into the recovery mode.
