Unlock bootloader and root new device - Nexus 7 (2013) Q&A

I am going to purchase a Nexus 7 2013 and will be wanting to unlock the bootloader and root the device straightaway. I would be grateful if someone could tell me the best way to go about this. Should I carry out these tasks with no ROM updates applied, i.e. on 4.3 or should I update to Lollipop first? Thanks in advance.

With the nexus 7 its as simple as typing fast boot OEM unlock, but here is a more comprehensive guide on the matter. http://forum.xda-developers.com/showthread.php?t=2381698

Unlock the bootloader before doing anything else, as it will wipe your data in the process.
If you plan on staying with the stock rom, don't bother rooting or installing a custom recovery until you've updated all the way to lollipop, as it can cause the ota updates to fail and you'll just lose root with each update anyways. Beware of taking this route though, the are lots of posts around saying that the latest ota update bricked devices. Might be safer to fastboot flash the latest factory image directly.
If you plan on using custom ROMs, go ahead and root it and install custom recovery then flash away to your heart's content. You may need to update the bootloader to latest version first to successfully flash lollipop ROMs though. I think its version 4.04, and there are flashable zips for doing this somewhere around here that worked great for me.

Many thanks. I used the excellent Nexus Root Toolkit.

I unlocked the bootloader, updated to Lollipop 5.0.2 by flashing the latest factory image, then rooted and flashed TWRP. I would now like to flash custom ROMS. You mentioned I may need to update the bootloader in order to successfully flash custom Lollipop ROMS? Am I correct in thinking I will have the latest bootloader, now that I have updated to Lollipop 5.0.2? Thanks.

Yep, you're correct. If you flashed the factory image, you should already be on the latest bootloader. :good:
By the way, 5.1 factory image finally was released today for this device.

Great, thanks for letting me know. Do you recommend I update to the 5.1 factory image before I flash any custom ROMS, or doesn't it matter?

Doesn't matter, though you may wait for the custom ROMs to update to 5.1 so they will have the latest binaries.

OK to get a few things right here, you need to have stock recovery to install OTA, no it won't relock boot loader, yes it will erase CWM. Your rom needs to be 100% stock (including boot loader, kernel and radio aswell as rom and recovery).
The way I just went to 4.1.1 (takju) I was running the preview JB Google IO rom anyway so in CWM I reflashed that to undo any system changes I made. Then using Mskips nexus tool kit I used it to flash stock recovery and then BOOT (NOT FLASH) to CWM. Find the update and flash it. Before you do all this use titanium to back up your stuff, do a nandroid and get voodoo OTA root keeper so you get root back after the update.
Then using the tool kit again I used it to flash CWM back. Then your done. I won't give further instructions but for further reading efrant has very good posts about this stuff, mskip has very good instructions on his tool kit in the thread

i'm still a little confused. my phone is completely stock. it's a takju 4.0.4. i don't want to wait for the OTA for jb 4.1.1. i was going to use the nexus tool kit to unlock the bootloader ( i believe that's required to boot it into cwm) then run the OTA update that people posted for my version to update it. I don't care about keeping cwm or bootloader, just want the update now and keep the phone still stock. i also want to make sure that i'll get OTA updates in the future. It looks like I can just boot it into cwm without flashing it, so that's what i'm going to do.

Yeah you can but you need to unlock the boot loader to do it, which wipes your entire phone so back up any thing you want to keep like photos or music. When the bootloader is open you can just leave it and just lock it if you need to send for warranty. Or if you already have root but locked boot loader there is a free app to unlock it on play store

once, i update the file using the nexus toolkit to boot into custom recovery, once it updates, it will lock the bootloader and the phone will be back to stock right? or is the bootloader going to stay open.
also, will i still get future OTA updates if i just do the update by booting into recovery and not flashing cwm?

Once you unlock it the bootloader stays open until you choose lock I again. You can still get ota but remember you need the matching bootloader, kernel, radio and unmodified system and recovery. So just booting cwm is fine to apply and then after its applied the patch you can flash what ever you want again. I find its always a good idea to make a back up of a 100% stock rom and keep it on the pc just in case. This is all simple and quick with the tool kit

Hey, first, thanks for the replies. Second, if I unlock the bootloader to install update, make no other changes, meaning everything else is stock and the update is googles stock update, them once the update is done, can I run the toolkit again to lock the bootloader. Doing this will it bring my phone to same everything as a stock ota updated one? Or is me unlocking and then locking bootloader going to cause me to have a different version for the next ota

No worries its fine. Yes after you have successfully applied a stock OTA patch onto a stock rom then you are running the same as everyone. Their are minor regional differences, like takju and yakuto (what ever lol) toro, toro plus etc but flashing a ota patch from a different build won't work on a rom that doesn't match.
You can go to the Google developer site and search for the full ROM and you know definitely its 100% as its meant to be, the patches just write over the bits which change in updates. The thing to bear in MIMD about flashing the whole ROM from Google site is that it will wipe your entire phone

OTA Update re-enable?

Hello all,
I'm using 4.0.4 on I747M with telus. Had to delete the 2 files to disable the OTA update notifications since at the time there was no root for 4.1.2
Now the question is, i've done 1 click with unified toolkit by mskip to root, flash etc.
Can i simply flash any 4.1.2 custom rom or manufacture rom or should i restore to factory default, do the update and then root and do custom rom?
Or naturally is there a simply way to get OTA updates enabled?
Thanks for you help!
to clarify, you are rooted and running the 4.0.4 stock firmware?
if you want to receive OTA updates from your carrier, you need to be on the stock/unrooted firmware.
if you want to run a custom rom, and you're already rooted, install a custom recovery like clockworkmod or twrp. this will allow you to flash a rom. be sure to only flash roms that are intended for your model.
Yeah i already have CW. just wanted to make sure if going different build will cause issues.
Thanks!

if you have an i747 or i747M, stick with those ROMs as anything else will cause serious problems with your device.

if you're on an i747/i747M than that should be just fine. remember to make a backup first and perform a full wipe before flashing. if you're unfamiliar with some of these techniques, follow the link in my signature. it outlines what procedures to follow to safely get you running smooth.

[Q] After flashing TWRP recovery, Nexus7 will get an OTA from google?

i dont see why you wouldnt still get ota updates. i could be wrong, but pretty sure youll still get them
for flashing to stock, rooting, and unlocking you can use the nexus root toolkit.
http://www.wugfresh.com/nrt/
it will automatically download the stock image file which contains the stock recovery. i think its boot.img (within the stock file). you can also manually download the stock file here: https://developers.google.com/android/nexus/images

Are you sure is it possible to get OTA from google without stock recovery? If its true, is a good news!
The stock from [email protected] is have stock rom & recovery, I want to flash only stock recovery without rom and reset.
Thanks.

im not 100% sure because this is my first nexus device. but on my n7000 (international galaxy note) i got updates just fine with a custom recovery.
use the tool kit in my first post to flash stock recovery.
I got an OTA update on my deb/LTE with TWRP and SuperSU on it.
After the update stock recovery was flashed and my deb was unrooted again.
Just flashed TWRP back and the SuperSU zip. Everything is working fine!:good:
@shyd
Your bootloader are unlocked?
I will waiting to the next OTA to check it (with root, unlocked & TWRP recovery).
Thanks all.

Sure, otherwise I couldn't alter the recovery!
The bootloader lock/unlock state hasn't been changed by the OTA update!

Also, if you want the OTA but don't want to have to unlock and root again, people usually post a flashable update that you can install via your custom recovery.

Questions on how to go from VZW N4 LP to MM

Hope the title isn't confusing but I wanted to ask some questions and get some answers without blowing up hsbadr's thread on how to go from LP to MM. So here it goes.
When flashing the full firmware update coming from an already unlocked and rooted Verizon on LP to MM what happens?
Are you back to stock MM rom from Samsung or are you on a modified version of the MM firmware? In other words can I flash the full update and just stay on that base rom?
I believe that is the case and if so hsbadr says we can root and go through the process of unlocking again. What root works best and is it permanent or is it temporary? Is it really temperamental like on LP or will it stick easy enough to unlock?
My purpose in asking is I would like to do all this in phases and help others understand. If I flash the full firmware then I would like to stay on the base rom MM for awhile and when I have time I will unlock the phone.... Again. However if I can't have perm root then flashing the firmware would need to be done in one go with the whole unlocking process.
Any answers are very much appreciated! Thanks ??

Which full firmware? hsbadr's* is a hybrid Lollipop/Marshmallow version which I don't think would be a suitable daily driver. The full firmware from sammobile will give you Marshmallow as Verizon intended. Either way, your bootloader is locked. Using hsbadr's means your bootloader can be unlocked. The official version, not so much.
With the full official firmware being available, I would not advise using the update.zip method in other threads. Either flash the official firmware in ODIN or take the OTA update. Either way, you'll have a locked bootloader. Rumor has it that you can flash a Lollipop firmware and re-root, but I wasn't about to try. I could bide my time and let the developers work their magic.
* Also extending credit and thanks to ryanbg and beaups who together worked to get us an unlocked Marshmallow bootloader.

If you want root... if you think you'll want root... just bite the bullet and do it. Jasmine ROM has all of the benefits of the Verizon version of Marshmallow. If that's good enough, stay there. If you want to explore, that option will be available as well.
Yea I'm talking about hsbadr hybrid. I'm unlocked and rooted on LP using one of his roms right now. Just want sure what the hybrid version of MM meant. Thanks for the help and understanding. Makes sense now.

This might be it. Post in this thread and inquire before you do anything. You might need to flash and Unlock, again, but once you Unlock, you might be able to use it Unlocked/Rooted as-is. Again, though, inquire there.

Which CM13 version are you using? Have you upgraded the bootloader to MM yet? If you are using an older version of CM13 that was on the LP bootloader then you'll have to go through the unlocking process once more with the LP-MM hybrid firmware. If you have already done that and you have the MM bootloader then you can flash JasmineROM or PaulPizz as a close-to-stock ROM. Jasmine is probably the closest to stock.
