Does updating OTA require you to unlock again? Root again?
I can't remember, and I'm trying to help a friend. I want to make sure they won't have to unlock again and lose all their current data and settings. Thanks
My friend was rooted unlocked with CWM on stock and got the OTA. When it went into recovery, it asked him if he wanted to keep root, etc and he said yes. OTA went through, he kept root and didn't lose out on anything.

Hey Guys,
I've done reading about this issue but I did not find an answer specifically to the Nexus 7 device.
I bought my mother-in-law the Nexus 7 and she loves it. However, she will be going back home (which is far) and I was wondering if an OTA update comes, will she be able to update? Will it mess with the system itself if updated over?
Do I have to unroot first, then OTA update, then reroot?
I will not install any custom rom. I will just have it rooted that is it.
Thank you
I unlocked my bootloader and manually rooted [superuser zip in CWM], then I installed the system update that updated it to 4.1.1 [JRO03D], and I still had root, so I'm pretty sure the updates on the N7 will keep the root.
However, you can always try "OTA root keeper" in the play store, it's supposed to restore root, in the event that an OTA update unroots it.
I downloaded it before updating because I thought I'd lose root with the update, but I didn't have to use it at all.
But I'm no longer on the stock rom, I switched to the ParanoidAndroid rom, it's excellent.
I see. Do I need to unlock the bootloader in order to root? Is it true that unlocking the bootloader is only needed if I want to install custom ROMs right? Can I just have root?
Thanks again!
You have to unlock the bootloader in order to root.

Unfortunately no, because there is no known exploit for loading an insecure boot image, in which case you could use 'adb' to push Superuser to /system/.. But unlocking the bootloader isn't a big deal, except for the fact it erases all the data. There are ways to back it up via adb, and I think the N7 Toolkit has backup & restore options.
I'm looking to root my phone but I don't want to flash any new bootloader or custom roms. I'm under the impression that I'll still be able to get OTA updates if I do this. My question is if I download and install an OTA update will I still have root on the phone or will it remove root? Thanks!

I was still able to receive and apply the OTA after rooting, but the OTA did cause me to lose root. But re-rooting was pretty painless.
Its sure than rooting phone you receive OTA and can install it?? If yes, I want to root my phone, only root, i dont want to change anything more for receiving OTAs.
How can I do? just only root, any link to the safest way?
Is the same way when I receive an OTA and i have to root again?
many thanks.
1. You can use an app called OTA Rootkeeper. Use it to hide root before you accept an OTA, then use it to restore root after.
2. Yes, you can use adb commands (possibly the Nexus 4 toolkit as well) to temporarily flash clockwork recovery and obtain root. You will need to unlock the bootloader though, and that will factory reset your device.

Good advice for OTA Rootkeeper! If I head down this path I'll make sure to use that. I'm still looking around for the best way to root without unlocking the bootloader or factory reseting.
Superuser contains a built in 'try and preserve root' function which worked well when I updated to 4.2.1
I've unlocked the bootloader of my Razr M and installed a 10.2 ROM. Right nowI'm doing some experiments with the stock Verizon 4.1.1 ROM, restored through a TWRP backup I've done... I just need to know:
Now that I've unlocked the bootloader and installed TWRP, if I accept the last Verizon OTA (98.18.78) am I going to lose the bootloader and TWRP? Basically, will I be able to get to the recovery / revert to CM10.2?
Thanks in advance!

You won't lose the unlocked bootloader but you will lose root. Also, the OTA probably won't install unless you use stock recovery and restore any apps that you got rid of. I didn't do the OTA, but these were some of the issues I've seen other have had. The simplest solution is just finding a stock ROM on here, I think there are a couple in the Dev area that are based off the latest OTA. Also, there is one on Batakang.
My phone is prompting me to update to B29, but when it reboots, it brings me to the TWRP recovery, and I can't seem to find an update.zip or anything. Is it not there, or am I just looking in the wrong places? Will it even successfully update with the bootloader unlock (not the official unlock) and TWRP installed, or do I need to restore the stock recovery?
My phone was originally on B20_boot, but I've since restored using Draken's TWRP files to get to B27 (I'm assuming still B20_boot).
You won't be able to OTA update with your system modifications. DrakenFX has flashable zips posted in another thread, but beware there seems to be quite a few bugs in b29 (I have no in-call audio personally).
You can use my updated post to B29 (bootstack and boot/system) flashable files are there.

So why am I getting the notification, then? Will it just keep popping up, or is there a way to block it (even though I'm not rooted)?
As for the bugs, I've seen plenty who have upgraded to B29 without issues. How did you update? Could it be something with updating via TWRP?
Have you personally heard of anyone having problems with your update file? Will it wipe my phone (ie: will I have to reinstall everything)?
Bootloader unlocked, normal twrp flash as per DrakenFX's instructions. And yeah but a lot of people are in both boats so your milage may vary.
Thanks. Do you think I'll be able to keep my data partition intact? I really don't want to set everything else up again. It's getting old... lol.
I wiped everything, so I'm not sure. Maybe that's why my stuff is broken lol
You can't do system updates with custom bootloader's. You are getting the message because you still have the update program on your phone. Look for some sort of update.apk and disable or uninstall it.
I didn't think you could do that without root.
Oh well, I plan on putting root back on soon anyway.
That would be interesting, if true. You would think a "dirty flash" would cause more problems than a clean one.
What about the whole "can't root B29" thing. I've seen a comment where someone said they could not root B29 since they didn't root before the upgrade. I'm not rooted now, but I am bootloader unlocked with the latest TWRP. Should I be ok to flash without rooting first? I was hoping to root afterwards, and try to figure out a way to make Magisk work.
You can't root locked bootloader B29 afaik at the moment. You'd either have to unlock your bootloader or stay on B27 to get root.
I am bootloader unlocked.
I'm not rooted now, but I am bootloader unlocked with the latest TWRP.

I'm on 19s, with an unlocked bl and rooted. I see that the 20s update is available. If I update, will I lose root and unlocked bl? Thanks!

I bought the phone it came with stock rom 5.8.018S. I installed TWRP and flash rom 5.9.020S (T.A.R.S by Steve/Grosshop/Google Edittion), all these rom come with pre-rooted.
Once you installed TWRP and backup your system, you can flash any rom really I haven't had any issue.
Root is easy anyway, just flash Supersu via TWRP from what I read for this phone.

Thanks for your response but it doesn't answer my question about accepting the upgrade to 20s and what will or won't happen. I also have twrp installed and am rooted on 19s. Ideally, I'd prefer to upgrade without having to re-root and unlock my bl again but if that's the case, so be it. Just wanted to know beforehand.

Sorry I was not sure it's OTA update by the system or flash it by yourself when you mentioned about the update.
Why would you accept the update when you can flash all the rom available, the update can only mess up/complicate things on your phone in my opinion.
You will get same stuff as in the 20s roms.
Based on what I have read I am pretty sure you will need to re-root and unlock the BL again (because you will need to revert these changes to actually apply the OTA, it will fail otherwise). I ended up flashing a Cydras ROM because I didn't want to deal with unrooting, etc, to receive the OTA (since I already had a rooted device and it would fail OTA).
If you want to do the OTA, then you should do it before doing any root/unlock bl. I would then do the BL unlock, install TWRP, and take a backup of the system image.
Today I Gott the OTA Update for the Lex720 for s20

That's what I was afraid of. Might as well give some of the custom roms a shot if I'm going to end up wiping, etc. Thanks!
