How to force firmware upgrade?

My Reader is bricked, and I can't go into recovery mode. Maybe the Sony firmware upgrade could help. But I can't run it because it says the firmware version is up to date, which is true. Is there a way to run the upgrade anyway? A hidden switch or workaround? Maybe an older version which is not linked in the wiki? Where to get?

Solution

1. Download an official updater (PRS-T1_Updater_1.0.05.11130)
2. Used 7-zip to extract its contents
3. In PRS-T1_Updater_1.0.05.11130.exe\eBookUpdater\scripts\u pdater.xml
find the following line:

"return updateVersion <= deviceVersion"

and change it to

"return updateVersion >= deviceVersion"

This way it will run the firmware upgrade regardless of your current version - except for some newer firmwares (e.g. 1.07), those check the version on the reader itself and deny it, if it's a newer one.
