should recover ability to boot from SD. It can be installed in the "usual" manner (no SD card required, unpack on a PC, run "flash_reader.bat").
The units with 1.0.05.12140 installed over non-jailbreaked firmware, or pre-installed at the factory, are not hackable at present time.
First post here. My wife had this reader for christmas. Unfortunatelly, we did the update. Are we stuck forever or is there any chance ? For the moment, we just want to install some apk like a real facebook app and maybe a rss feed reader.
BTW, thanks for that thread, it has interesting information.
