[Q] How to Block OTA Updates & Keep Root + Unlock

Wow, I thought someone here would have the answer to block OTAs at least. But hey, I totally appreciate the lack of "I don't know" posts that plague other boards.

Hi, v1ncent...

First off, your question properly belongs on the Nexus 7(2013) forum... and not this one.

Secondly, your sense of entitlement to an immediate fix to your problem is likely to irk and irritate many who may try to help you. Your original posted question is less then 24 hours old. Give people a chance!

Thirdly, did it occur to you, that the reason for a lack of a response with regard to blocking OTA's is because it might not have a solution... or that people might not have one.

Often, when I look at a posters problem, and I think "How can I help this guy?; What do I know that might assist him/her?"... and I'll turn the problem over and over in my head... looking at it from every angle... and hopefully I'll come up with something; it might not be much, but at least it's something.

But if I have nothing, then I post nothing.

Anyhow... I actually had a response prepared, which I was just about to post, just before you posted your sarcasm infused post.

Here it is (...and for what it's worth)...

I am running my Nexus 7 2013 Wifi Only w/4.4.2 unlocked and rooted thanks to Wug's Nexus Root Toolkit and was wondering 2 things:

1. With the new updates rumored to soon be coming to our devices, I'd like to block any updates to 4.4.3 until I can find a way to keep root and unlock (probably will wait for Wug to update his toolkit). Is there a way to block my N7 from receiving updates until I'm ready for them?

2. Is there a way to receive the 4.4.3 update when it rolls out and keep my N7 rooted & unlocked?

Thanks.

Hi, v1ncent...

With regard to blocking OTA updates... I have read about an app called FOTAKILL, which apparently blocks OTA's, but I've never used it myself... and so can't really comment on it. . Do a bit of Googling around about it.

With regard to your second point... (and I'm extrapolating here, from my knowledge of how the older Nexus 7 works)... an OTA update will cause your device to become unrooted, and you'll also loose any Custom Recovery (CWM/TWRP) you have installed... but your Nexus 7's bootloader will remain unlocked... unless you explicitly relock it yourself, usually with the fastboot oem lock command.

So, yeah, you'll have to re-root after the OTA.

Hope this helps.

GedBlake: thank you for your reply, it's much appreciated! I will check on FOTAKILL. From what I have read after asking my question here is that there is some talk that paying for SuperSU to keep root may work in regards to keeping root from 4.4.2 to 4.4.3. I will try to delay updating if I can, but if I can't I think someone will come up with a simple procedure to root 4.4.3 after updating.

I love xda; the people here are FANTASTIC in coming up with new approaches to all manner of needs, so much so this is one of the few times I ever had the need to ask a ?, usually after searching I always find an answer.

Secondly, in regards to the first part of your reply - wow you couldn't have possibly misread my post more. I'm glad despite doing so you were nice and helpful in the second half. Everyone has a bad day, no worries man. I was actually glad that here, despite many other places when people have no solution they don't reply. I meant every word of my post, no hidden meanings. I'm glad despite the misread you still helped out; it's appreciated.Thanks!

Don't know how well it works, but it might be worth checking out.

Yeah, it's called Survival Mode...

...in SuperSU Pro (paid-for version) settings, there's a checkbox option to enable Survival Mode... and when ticked, this message appears...

SuperSU will actively attempt to keep superuser access, even across OTA updates

Don't know how well this feature works... I just re-root via TWRP after an OTA... so I've never had cause to use it.

Apologies for my rather brusque post earlier... it was uncalled for.
