[Q] rooting erases the phone?

ive read in some other posts here that rooting our gsm gnexus will erase the phones data/settings/etc. because it is an "oem root". is this true? does it apply to the gnex toolkit?
thanks!

Rooting does not erase data/settings. HOWEVER, if you unlock your bootloader, it will erase everything. All toolkits that I have seen, root by unlocking your bootloader first (if it is locked).
Use this, and you will root without losing anything, locked bootloader or not.

why does unlocking the bootloader erase everything? and that is necessary to flash a new rom or kernel, correct?

Because it just does. It's a security thing. But it doesn't matter - with what I pointed you to in my previous post, you can root, flash a custom recovery, backup everything, then unlock your bootloader and restore the backup.
An unlocked bootloader is not required to flash a new ROM or kernel if you have root. You cannot, however, flash things through fastboot, but it doesn't matter.
In any case, I would recommend you unlock your bootloader and leave it unlocked.

security reason...if you have a phone with the bootloader locked and a lockscreen password, ur phone is secure (EDIT: usb debug need to be disabled to be real secure)...so if u lost the phone for example someone could unlock the bootloader and with root permission could get ur personal data..instead in this way if he unlock the bootloader the data in it is wiped..
with the bootloader unlocked ur phone give u free access to the system, so u can root it, flash rom, kernel and everything
in case a day u change idea, u can also relock the bootloader (this will wipe again ur phone EDIT: will not wipe it)..this is usefull to get warranty for example
there is also an exploit, mentioned before in the thread, that is able to root ur phone without unlocking the bootloader..but i suggest to unlock the bootloader as u have more control of ur phone by having access to fastboot commands

thanks for the help guys! i have to figure out if i really want to wipe all my data. if i use titanium to backup everything, then unlock bootloader, can i still restore the same backed up data, or does the changed bootloader make that impossible?

Not entirely true. You need to have USB debugging disabled in settings as well for it to be secure.

Not true. Relocking the bootloader does not wipe anything.

You do NOT have to wipe all your data.
Follow these steps:
1) Root your device using the method I linked to above;
2) Download ROM Manager from the market;
3) Using ROM Manager, flash CWM recovery;
4) Reboot into recovery and perform a backup;
5) Copy that backup OFF of your device;
6) Unlock your bootloader; <== This will wipe your device, including everything in /sdcard...
7) Copy your backup back to your device;
8) Reboot into recovery and restore your backup;
9) Done. Now your bootloader is unlocked, you have root, and your data/settings are exactly how they were before.
EDIT: Yes, you can use Titanium Backup once you root, but using CWM recovery is easier and faster.

didn't know that..it makes sense anyway
thanks for the corrections

so the bootloader is not affected by a CWM backup.
this is so helpful. thanks so much guys! i thanked both of you for your replies!

Always root the first day to avoid this!

[Q] question about bootloader

hi sorry for noob question.
i rooted my phone a while ago, and i think i remember unlocking bootloader but im not sure. i DO have TWRP recovery, does that mean that i had to unlock my bootloader to get it; thus it is unlocked?
thanks!

Since u r rooted and already have custom recovery flashed,there's no need to do anything else..u can now flash custom rom of ur need via recovery.

International Samsung devices have an unlocked bootloader when you buy it.
So it's necesseray but already done by the manufacturer.

You didn't need to unlock to use adb sideload, but now that you have it unlocked, personally I would leave it unlocked. You have more options to recover from problems with it unlocked and also if you ever want to root, you don't need to do the wipe/restore sequence again.

It's a recovery module.Where you can create backup, reset the device, restore the backup, etc etc!

relock boot loader after rooting?

ok, this is driving me crazy. had every nexus except the 6, got the 5x. unlocked bootloader, ok. flash twrp. cool. install root files, great. set up android pay, denied due to unlocked boot loader. went to lock boot loader... wants to do a factory reset.... ok..... now it just boot loops in twrp formats cache, and phone gives errors about corrupt system, different system, blah blah. so right now im bootloader unlocked, rooted with twrp. how is everyone relocking the boot loader?

You have to be on stock recovery to relock the bootloader. You can hardbrick this phone trying to lock it with TWRP installed. Consider yourself lucky?
Android pay is not working because of root, not the unlocked bootloader. Start reading about systemless root

yes, i flashed the systemless root on my n5x ( i have a regular nexus 5, twrp, bootloader locked, and android pay works with systemless root) so i do now about this recent development. can it be flashed in stock recovery? i just feel like im missing something?

From the [GUIDE] Unlock/Root/Flash for Nexus 5X that you should have read before farting around with the phone:
Important: do not relock your bootloader unless your phone is fully stock. You must flash the factory images first in order to remove root and custom recovery (if you have them), if this precaution isn't taken you may end up with a brick. Please see section 11 of this guide for full instructions on how to return to stock.

Use the guide I linked to to flash the stock images. Then use the guide again to root the phone with systemless root.

thanks for the link, thats one of the first things i read when i started looking but it doesnt really talk about relocking the bootloader unless going stock. im just trying to keep my systemless root and have locked bootloader. sounds like i should try reflashing stock recov after rooting and then try to relock bootloader?

If you have rooted your phone, you are not fully stock. Therefor do not relock the bootloader.

The 5X is my first Nexus so bare with me. Why would you have TWRP installed with a locked bootloader on the OG Nexus 5? What is the benefit of that?

well there was an app "bootunlocker" which let you unlock it on the fly. also android pay requires a locked bootloader.
so i have locked bootloader, systemless root, and twrp on my OG nexus 5.
just cant seen to relock bootloader and somehow reroot again since NOW nexus 5x required device be WIPED when relocked

Oh, that sounds pretty cool actually.
I don't use Android Pay but I know you do not need a locked bootloader to get it working. Which version of SuperSU did you install? Cuz every time I see a 5X user with working Android Pay, they have systemless root and even a custom rom. I am pretty certain that I read that you just need to delete /SU/xbin_bind to get Android Pay working with systemless root.
Edit: I've seen it mentioned in the SuperSU thread I think, but it is explicitly mentioned in this Nexus 6P Android Pay thread

Yes. This is common knowledge.
Android Pay looks for changes to the system partition only. It doesn't give a rats ass if the kernel, recovery, or boot image are modified, nor does it give a flying **** if the bootloader is unlocked.

No problem. Sorry if I came across a bit hostile. I may have been up too late last night.
Android Pay is also working on some ROMs. Cataclysm for one. PureNexus will be comparable next update too.

Relocking bootloader question

Hi hope someone can verify.
I'm running stock 3.2.7 unrooted with stock recovery. The bootloader is still unlocked as I tried out a few custom ROMs about a month back. I now want to wipe and sell the phone so need to lock the bootloader. Can I just do the standard OEM lock in adb or should I also sideload the full 3.2.7 update zip again?
Thanks

just oem lock it. but everything will be removed when you do that.

Thanks, I thought so but I had to check. Strange... after rooting phones and installing custom ROMs for maybe 8 years, I don't think I've ever relocked a bootloader.

It's safer to flash stock again then to relock bootloader, even if you think you are stock (including recovery) maybe you are not.
But except the booting screen, you won't gain anything from relocking bootloader, even the warranty will work with bootloader unlocked.

Thanks, but I plan to sell my OP3 to a high street store that buys and sells second-hand phones and tablets. Although it's only 3 months old and in immaculate condition, I'm guessing they may be reluctant to buy it if the start up screen says 'this phone can't be trusted...'
No choice in this situation - I will need to relock the bootloader I guess.

If you lock the bootloader, everything will be wiped and phone won't boot till you flash OOS.

Thank you. So after OEM lock, when you say flash OOS do you mean sideload a full update zip? That's what I was asking in my original post.

Ta mate. I already saw that thread but as I'm running a clean sideloaded OOS that has never been rooted, I am already back to stock. Anyway, as opinion seems to be divided on whether OEM lock alone is enough, I will also sideload a full OOS update zip again to be sure.
Won't be doing it for a few days though so it's all academic at the moment.
