Q re unlocking, rooting and OTA updates

Hey all just wanted to clarify something before venturing forward.
1) Unlocking without rooting will still enable OTA updates to be pushed to my yakju GN?
2) Rooting will disable future OTA updates thus requiring manual ROM updates? Each manual update will thus wipe the device and require manual backup and restore of data and apps?
3) What is the reason to unlock the bootloader without rooting? It sees most things like customising boot screen animation, changing icons and using a firewall requires root not just unlock.

Bump! 10cghar.

1. Yes
2. Rooting will not affect OTA updates. If you make any changes to anything outside /sdcard/ it'll cause problems. Manual update will not wipe the device.
3. Unlock bootloader + no root.... this way you can root afterwards if you decide to root and then backup your apps/data.
If you don't unlock.. then one day you decide to root, and you unlock bootloader you lose everything and can't back it up.
You can't change boot animations without root.

As well, unlocking the bootloader allows you to use fastboot commands, which you would otherwise not be able to use.

After rooting are we supposed to lock the bootloader back again? What is the reason for locking it again? Is it to prevent malicious apps from messing with it or unintentional modification?
If after rooting, I locked the bootloader back, can I still install other ROMs and multi boot other ROMs?

I would highly recommend you leave it unlocked. If you lock it, you will lose your data the next time you have to unlock.
Also, having it unlocked allows you to use fastboot commands.
There is no good reason to lock it.

hmm that sucks. I relocked the bootloader because that's what some tutorials said to do.

Who was advising that? In any case, if you're already rooted, you can do a full nandroid backup. You could also download TiBackup and back up all your apps and data. Either way, you have something to fall back on when unlock wipes the phone.

Hmm more than one tutorial I read added that step. Even one on xda. I'm not going to go find it now. Anyways it will be a hassle, that's all, nothing I can't handle. I already have Titanium Backup paid version so my apps and data are covered. I don't think I can do a Nandroid backup though because I encrypted all the data on the phone. When rebooting into CWM, it gives me an error when trying to do Nandroid backup. Says it can't access sdcard.

if I unlock, keep stock recovery and stock ICS and root...
Can I still receive OTA updates if I do things like change boot animation, change the default launcher, use samba filesharing?
Thanks guys

Changing the default launcher (as long as you don't delete the original launcher), and using samba will cause no issues. Changing the boot animation may cause you an issue, but just back up the original file before you replace it, so you have a copy just in case.

what about using adaway (as it changes hosts file)...

what about busybox?

No, it won't affect anything. Adding files to the ROM doesn't affect it. What does affect the OTA update is deleting or modifying existing files.

Downgrade GSM Gnex to 4.0.2

Hello
Today i recieved the jellybean ota update. its not working. i searched for a while and found out that ill have to update it with something called cwm and this requires root, but i dont want to root my phone. so i thought it would be possible to downgrade my device but apparently this also requires root. I have an unlocked bootloader but is there no way to update/downgrade my device without using root?

cwm does not require root, just an unlocked bootloader.

4.1.2 OTA Update

Hello Everyone,
I haven't had time to search the forum for my question. If I push the 4.1.2 update, does anyone know if that will re-lock my Nexus? My Nexus is unlocked and I keep the stock 4.1.1.
Thanks
Eric

No the update will not relock the bootloader. It will remove root privileges though.

Any way to keep root privileges, or restore them after the upgrade (without a full system wipe)?
:highfive:

If your bootloader is unlocked re-rooting is easy. Just fastboot boot a custom recovery and flash a Superuser or SuperSU zip

1. Voodoo OTA Rootkeeper in the Play Store.
2. Backupt Root with that app.
3. Update via OTA.
4. Restore Root with the Rootkeeper.
5. Profit.

disable annoying 4.1.2 OTA system update notification?
How do I disable the annoying 4.1.2 OTA system update notification? I am rooted, have a custom ROM and want to wait until that ROM is updated to 4.1.2.
I have searched and can't find a clear answer. All I've found is answers for gingerbread... Or vague answers like "freeze the updater file with Titanium Backup!" I would if I knew the file name and where it's located.
If there's a file I can freeze or rename, please tell me the exact name of the file and exactly where it is.
I would be using Root Explorer or Titanium Backup.
THANK YOU!

[Q] Lost root from efrants root without wiping (4.1.2) to Android 4.2 update (solved)

Hello all,
I already searched the forum but I did not found any good answer.
1. In the past I've succesfully applied root access without unlocking the bootloader while still beeing on Android 4.1.x from this guide:
http://forum.xda-developers.com/showthread.php?t=1894717
2. Now I've got a 4.2 OTA update. Before applying it I used Voodoo OTA rootkeeper to keep a backup of su.
3. Restored su with Voodoo OTA rootkeeper
The result is that I have again root access from shell but when I want to use Apps which require root I always get failures and even no confirmation dialog.
How do I get superuser working (fully root) like before?
Thanks,
therealmarv

How should I flash that without having CWM? I think I need a manual repair :/

Is your bootloader locked?
If not...use my guide (in sig or stickied) to back up data before unlocking...
If so... "fastboot boot recovery.img" and flash the file.
The recovery is only being booted into...not written to the phone; so you'd still be stock rooted.

How in the world you not have a unlocked bootloader when you rooted before..
That aside, do remember to keep the bootloader unlocked next time..

The same sort of exploit that was used in ICS was eventually found for 4.1.1 that allowed root without unlocking.

What i mean is how can they not unlock the bootloader after rooting..

I did not unlocked bootloader because I thought it is not necessary (and I also thought it will affect OTA updates). So just to get it right: I can make a backup of my phone, root it, unlock bootloader and recover the backup afterwards so that no data is lost?

Ok I solved my issue (having su access via adb and locked bootloader) with this thread:
http://forum.xda-developers.com/showpost.php?p=27085483&postcount=141
1. I unlocked the bootloader with the link above
2. flashed CWM with fastboot
3. flashed SuperSU CWM ZIP for getting root again
So I now have fully root, unlocked bootloader and cwm great.

[Q] OTA updates run automatically?

This is my first Nexus. If I unlock the bootloader and root, and stay with rooted stock, would a future OTA update relock the bootloader and undo root?
Also, are the OTA updates automatic, or can I choose not to install the update?

Once you are unlocked, you won't become locked unless you manually lock it. This is the case even if you accept an OTA or factory restore.
Some OTAs are mandatory like the one most people got when they turned on the unit, however most are optional and won't install unless you choose to, either on purpose or by accident.

However, to be fair, the DEB JLS36I update out there right now will cause you to lose root. It does not lock the bootloader, but it does whack root and custom recoveries. Unless you choose the option in TWRP to recover root after the install, in which case it rolls back the update and keeps both TWRP and root, meaning you are as you were as before. A few days later, you get the prompt to install the update again, and the circle of life continues.

Does that mean rooted and unlocked on JSS15R I can get the next OTA update but I loose root? I dont have any custom stuff like recovery or rom, just unlocked and rooted for a few apps like titanium backup, cpu Z and gemeni app manager

You can get the update and just re-root.
However if you have modified or removed any files, ota will very likely fail. Removing stock app would be an example of removing a file. On the other hand disabling stock app would be fine.

What if I just bought a nexus 7 LTE and already updated to to JLS36I? How would I get root then? Hypothetically of course...

Same way you would if you hadn't installed JLS36I
Unlock bootloader
Boot into custom recovery
Install root
