I'm new to this forum and was wondering if I update my nexus 7 (2013)to android 4.4.2 without a unlocked bootloader, custom recovery, and not rooted, would I be able to root, get a custom recovery, and unlock the bootloader after I update?
Sure
sure you can root, get CWM and install custom roms .

Yes, you can do it at anytime. Just remember that unlocking the bootloader will wipe your device including wiping whatever is in your storage. Just like doing a factory reset it wipes Everything! AFTER you get a custom recovery you can do a factory reset from inside of recovery without wiping your storage.

Toolkits? Yes, the only one I can think of off hand is wugs, or something like that, either here or in the Nexus 5 forum. I've never used toolkits, have you given any thought to learning adb? It's not that hard, the fact that I can use it proves my point!

OK, this method was out since long time ago, but since not a lot of people know about this simple method, I am thinking of posting this thread to help a lot of people

Just follow the instruction and you should be able to temporary use the Clockworkmod recovery and able to backup all of your data (Make sure you got ADB driver installed though)

1. Root is not required for backup through recovery, whether running recovery that is on the device or booting recovery from your PC. Being rooted and having a custom recovery installed are two different things. Title is misleading.
2. Method still requires unlocking the bootloader (which still wipes your phone), you might as well flash recovery anyway.
It is neat that this is possible, but it seems rather redundant and unnecessary once you realize the only difference between booting into recovery from fastboot and flashing recovery is where the recovery is stored. The bootloader still has to be unlocked, if I'm not mistaken. If it doesn't have to be unlocked, then I can see the significance

As much as you're right, some people just wants to get OTA and stuff... For example, 3 of my friend who owns android wants to get OTA. Of course this isn't the most recommended way, at least it is there for people who wants it

Titanium Backup is just so useful. Such a helpful utility. I guess the easiest without root would be through imaging of userdata?

This was something I was thinking about while I was at work earlier today. While setting a screen lock and using an app protector app will protect my phone from unauthorized access while it is on, there is currently nothing that I am aware of that can keep a thief who is in the know about rooting and flashing ROMs from booting my phone into recovery resetting it, and modding it to his liking. My question is, is there a way to encrypt my recovery image (I use TWRP) to make it accessible only after a passcode is entered? Or is there a recovery out there somewhere that has this built in?

Even if you were to password protect your recovery, if you're worried about a tech-savvy thief they'd just have to toolkit flash (or adb if they had a brain) a factory build and poof.

Which brings up another issue I was pondering. Encrypting the bootloader, or possibly flashing one that can't run adb commands without a password.

Use bootunlocker for nexus devices (on play store) to lock your bootloader and unlock it when you want to flash something. If you do that plus flash the stock recovery and turn off USB debugging, your device will be secure. If someone can't unlock your phone and run bootunlocker, they will have to fastboot oem unlock in order to do anything, which will wipe your data from the phone. It adds more steps if you like to flash and modify things, but it leaves Android's security intact.

Stock recovery? So does this mean that the only way I can prevent a tech savvy thief from accessing recovery and flashing a new ROM is by not being rooted?

Pretty much. That's why a lot of companies require encryption and unrooted devices for Exchange purposes.

You can still be rooted (assuming you use the literal definition of superuser). With the bootunlocker app, you can unlock the boot loader, reboot bootloader, flash custom recovery, flash ROM/mod in recovery, reboot boot loader, flash stock recovery, and relock bootloader again with the app. Unless someone knows your password or pattern, they won't be able to do that. They can only erase the entire phone to gain access.

Ok, here's another question. How do I flash the stock recovery?
Sent from my Galaxy Nexus using Tapatalk 2
I ran techfanatic's one-click script to unroot and restore my phone (VZW Galaxy Nexus) to 4.2.2 . It simply locked the phone but didn't unroot or restore it to stock. When I power up into the bootloader it says I'm locked, but I still have root access and the custom ROM I installed. I need to revert to stock, unroot, and lock the bootloader so I can return the phone. Please help!
My guess is I can't flash the stock ROM and unroot the phone while the bootloader is locked. So what happens if I unlock the bootloader now? I'm not sure there is any stock ROM on my phone for it to go to after it resets everything in the process. Can I simply unlock it, let it do the reset, then flash stock, unroot, and lock it back up?
I have SDK and the stock 4.2.2 image on my Mac and would love to get it on there.
Thanks

You don't need to factory reset first or unroot, since you're flashing stock images, it will flash userdata.img, which will remove all /sdcard/ contents, and system.img, which will overwrite /system, which is where root was. Zepius had already told you this.

Hi guys
i'm a new user and PLEASE help me!
i want to root my new nexus 7 (2013) but i can't.
VROOT and Kingo detect my device but can't root.
unknown sources and usb debugging are activated and i tested with both mtp and ptp mode.
I used wugs toolbox and it did a good job. that is my suggestion. , unless you want to, at. this point, do the whole thing yourself with the SDK/abm.

if i want to root via wugs toolbox i have to unlock bootloader and my device will wipe.
better suggestion with no wipe?
I'm pretty sure you HAVE to wipe when your bootloader gets unlocked. This is why it's always suggested to root as soon as you get the device.

There is no way around wiping when the bootloader is unlocked. This is easy manually though.
First unlock the bootloader and install aTWRP custom recovery

Then you flash a root zip and you're done.

Hi guys
Noob here, but with a somewhat decent understanding of flashing and I'm kinda riddled by my current situation.
The current state of my phone is:
Locked bootloader.
Access to TWRP (2.8). Access to MTP and install function within TWRP.
OEM unlocking NOT allowed (since I can't boot into the OS).
So the logical thing to do (and as req'ed in dozens of threads with the same problem) would be to flash a custom ROM via TWRP's Install function, boot into it, enable OEM unlocking, unlock the bootloader and do whatever I want from there.
Except ... that all the ROMs I flash are stuck in bootloop. They go through the flashing process, TWRP shows success and then ... an endless android (or custom) loop when I reboot. I tried flashing PureNexus, Cataclysm and Chroma.
Any idea on what might be going wrong here (I thought of the vendor.img I have on right now being a wrong one, but I have no idea how to flash the good one without access to the vendor partition) ?
Any help would be appreciated, I saw that I could go through the LG flashtool/TOT unbricking method but I don't have i. a PC (I'm on a Mac) or ii. an original Nexus USB cable so that would put me back a few days.
Cheers
You can't flash a custom ROM with a locked bootloader....

You need to flash all the original stock images via ADB and restart from there

Yes, you can in recovery ...
Apparently not. Let me rephrase. You cannot flash a custom ROM with your bootloader locked and your phone work properly.... reflash all stock images through ADB. Take the advice or don't.
How did you get in this sh!tuation? Did you OEM lock with TWRP installed?
Anyway, the TOT method is most likely the only way to get it going again. I wouldn't waste my time doing anything else. Ask a friend/family member to borrow a computer with windows on it.

I'm thankful for any help, sorry if I was dissmisive. I'm not aware of flashing through ADB, just sideloading.
I can flash via fastboot, but can't right now because of my locked bootloader.
Presently I can sideload via ADB in recovery (which amounts to the same as flashing from recovery if I understand correctly ?) but any other flashing/thinkering via fastboot/ADB is verboten because my bootloader is locked.
If you're thinking of something else I'd be glad if you could detail your thinkings and the steps I'd need to make
@chafouin you just reminded me that Google is posting full OTAs. At least for the Android N developer previews. So theoretically you could factory reset from recovery and sideload an OTA. OTAs don't require an unlocked bootloader.

The stock rom? Why is that a problem? Put the device in fastboot and load. Locked bootloader does not allow custom roms. It allows stock.

In my experience *on the 5x* locked bootloader doesn't allow you to flash factory images.
I haven't tested with latest bootloader, but that has been he case with past bootloaders.
Other manufacturers and phone models handle things differently.
You can however now flash stock using the FULL OTA provided on the same factory image site. In that case you would use adb sideload, not fastboot.

Have you tried factory reset from TWRP?
If I were you I wouldn't try to flash to stock unless as last resort. Locked bootloader with TWRP installed is better diagnostic situation that locked bootloader with stock recovery installed. If you try to flash to stock it is too easy to overwrite your TWRP with stock recovery (it happens behind the scenes)
That is ok, if you are out of options, but I would exhaust all other options first.
