Xperia Z3 won't boot to recovery; boots normally instead

Hi,

So I recently rooted my device using this guide and updated to lollipop using the links inside. However, I realized I didn't update to the latest version (5.0.2 instead of 5.1.1). So I decided to do that, when I realized I couldn't boot into recovery. Whenever I tried, the device would turn off instead. I downloaded Quick Boot, and when I hit to recovery, it instead just boots up as if it was just a normal restart.

Help would be appreciated.

Semi-Bricked N7. Boots normally, but no fastboot or recovery

Hi All,

Really strange situation with my N7. I'm unable to boot into Fastboot or Recovery and when I do, it "bricks" my N7.

Or at least it does, until the battery drains after a couple of days. At which point, charging it backup allows me to reboot normally.

So the big question is, can I repair/overwrite the corrupted bootloader partition when it's running normally?

My device is unlocked, rooted, has SuperSU and BusyBox installed. In addition, I can run ADB commands, just no joy with the "adb reboot recovery" or "adb reboot-bootloader". I also have a TWRP created Nandroid backup, but without recovery working it's not really of much use at the moment.

Was thinking that maybe I could try sideloading? Or maybe there's a BusyBox command I could use to overwrite the bootloader partition? Or maybe there is something I could do while it's in APX mode using nvflash (if I can extract security blob from Nandroid backup)?

Any help would be appreciated. Seems a waste to install a new mainboard, as it still boots normally.

Many thanks!
