    After poor performance from Lollipop 5.0 I rolled my 2012 Wifi 16G N7 back to KK 4.4.4 and have been very happy with it. When the OTA for 5.0.2 showed up I didn't install it (I look at the notification every day and shake my head.....).

    Now that 5.1 has been released I'm wondering whether I will get it OTA w/o installing 5.0.2 or whether I have to install that version first, or will I only be able to get it by flashing it directly from the Google Developers site? I intend to wait until there is some feedback on this new version before installing it, but I'm wondering if/how I'll get it.

    I believe you'll have to install 5.0.2 and then when Google start rolling out the OTA you'll be asked to download 5.1 from there.

    It depends on how they write the 5.1 OTA. Sometimes it's cumulative - you download a different file, depending on what version you're on, that includes all the changes between your version and the new one. Sometimes it's consecutive - the phone updates to 5.0, the next day it updates to 5.0.1, etc. The only way to know is to wait until you get the 5.1 OTA.

    The OTAs that I've seen posted so far are for 5.1 LMY47D from 5.0.2 LRX22G. Given that I have been ignoring the notification that 5.0.2 has downloaded and is ready for install, do you think I will see a 5.1 OTA? Or will I have to install 5.0.2 first, or alternatively just flash 5.1 factory image? I've only ever once flashed, out of desperation to get rid of 5.0, and although I got it done it wasn't as straightforward as I had hoped. I'd also prefer not to lose all my data and have to start from scratch if I can avoid it, nor do i want to have to install and live with 5.0.2 for too long.

    So, a 2 part question: Will a 5.1 update notice appear if i haven't installed 5.0.2 or is there a way to flash 5.1 image w/o data loss? (I left my bootloader unlocked after the rollback).

    ok when you flash if you remove the W it won't while user data if you're doing a manual install executing each command one at a time as far as I remember.
    I don't think it'll be too much longer before the OTA goes out. Id just wait and when you hear its live, go ahead and update to 5.0. 2 and then you should also get the update to 5.1 right afterwards. the caveat is Google releases it in stages so your tablet could be one of the first to receive it or one of the last its all up to chance...
