How can i downgrade my tablet - Xperia Tablet Z Q&A, Help & Troubleshooting

I have the 4.2.2 ftf but i want to downgrade to this version without restoring my device. Because if i flash the 4.2.2 i will lose my data. Is there any way to downgrade without loosing data. I know i can backup but some games will redownload their data again.

The device will probably not boot if you flash without clearing data. IF it boots, you will have loads of errors and slowdowns

If you relock it, you won't lose root. Just make sure you are using stock kernel when relocking.
And it won't brick if you OTA. You might lose root, but it won't brick.

App updates won't brick your device, just system ones
