Tigr127 I get the message "Cannot load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device".
What is the exact sequence of events before the message occurs?
Tigr127 What do I do now? Is there any way to restore the phone without erasing all the data?
Unfortunately, probably not. The system is designed to protect user data against being extracted, which means that it's designed so that accessing user data requires the operating system to be working.
