[Q] System Update unroot?

Hi im running this rom
http://forum.xda-developers.com/showthread.php?t=741775
and i have recieved a notification for new software update (the one with better russian keyboard) and i tried downloading but it didnt work. Is it possible to do this (im rooted with unrevoked)? Also would i lose my root? i dont care if i do, im more interested in getting the new update and unrooting, thanks

yes you would lose root.
you are aware that if you install it you may never be able to root your phone again? well at least until one of the devs here finds a way.
i'm sure that update will get rooted and added to the ROMs soon if they haven't been already.
but other than that if you don't care then you should be find installing it.

i tried updating using system update, but it wouldnt work, my clockwork mod said the update failed
how can i update to this safely?
i know theres a way, do u know it?

It would be extremely easy to root the phone after installing this update...

You shouldn't try to install OTA updates to rooted phones. It usually won't work.
If you want the new version you can either install an RUU with the official version and then root, or you can install a newer rooted stock ROM through recovery.

yaaaaa bout that im on a mac, tehehe, and i dont mind losing my root

^havent heard of an ruu working on mac

The easiest thing for you to do is install a new custom ROM that is based on the new version (mine and a couple of others).

hence the third line of my post.

what if i just wanted the update and i didnt want my root tho?

Reboot into recovery, apply zip from sd card, toggle signature verification so its off, the update zip is downloaded to your sd cards download folder. Apply it. Then use unrevoked to root your phone again.

do i have to download the system update first, and then it will become update.zip, or is already do, can u walk me step by step through?

update: i tried what u said elmalote and it didnt work, what do i do now????

The ROM you are on has been updated with the latest OTA now so I'm not sure why you want to go another way than just flashing that ?

Is it a fully safe way to try install OTA update over the rooted ROM? I have branded ROM rooted using unrEVOked and I would like to try to install OTA update this way.

it didnt work for me, but if u try please tell me, it shouldnt screw up your phone.
does any one know how to install ota on a rooted phone

I'm not so sure about that. I've looked into OTA update downloaded into sd-card and it contains:
- system updates (new files, patches and so on)
- recovery img
- hboot update
- radio image
So let's assume that I toogle verification process (turn it off). OTA update will install over rooted ROM. After this, I have new recovery (because OTA update contains it).
I can see possibility of bricking my phone, when following situation appears:
- OS doesn't start-up (fell into boot-loop, whatever)
- recovery is back to stock, so no possibility to restore from nandroid backups
What do you think about that? Can someone confirm this is safe/dangerous?

Barthand, relax, i tried this, and i just rebooted my phone and it was fine. if you don't want to do it, then don't, but don't fret. it didn't work for me but it didn't screw up my phone either, now back to the main problem does anyone else have any solutions to install ota on a rooted phone.

Questions about rooting / recoveries ...

Hello
Since this will be my first nexus device , I have some questions regarding rooting and recoveries and what they affect on nexus devices specifically this nexus.
What affects the ability to receive official google updates?
If you are rooted do you always loose root if a new update comes? Does root affect the ability to receive updates?
If you have a custom recovery is it possible to receive official updates from google?
Thanks

I also have one quick question about rooting. I am totally new to this, I used android on my HD2 but it was always SD card version.
Does rooting affect warranty? I don't think it matters, but I'm with O2.

Official Updates
I think you can, however if you do you can lose root
Custom Recovery
Yes its possible. I believe koush is working on a stable CWM
Warranty
Yes, you will lose it and the Nexus will tell you before it lets you confirm you want to do it.
Im currently trying to get my Nexus back to unrooted status so I can send it back and get it on PAYG. I'll write up a tutorial once I've figured it out

1. Rooting your device wont affect your ability to receive updates, Custom ROMs do.
2. when you receive a new OTA you WILL lose root, this is the reason custom ROMs dont accept OTA updates.
3 As far as custom recoveries, I dont think that affects your ability to receive updates, Even then you can still flash an official update.zip via a custom recovery.

1. Eh grey area. Rooting doesnt void your warranty, but unlocking the bootloader does. As of yet there is no way to re-lock the bootloader.

I thought ota updates would also sometimes update stock recovery which would fail with custom recoveries and therefore no ota updates then.
So i was mistaken there?

So to be clear. I could do the following:
Get my phone
Unlock bootloader
Root it
Install cwm recovery
And this would NOT affect my ability to get ota updates?

You will get ota updates but it will not install it coz the cmw recovery, then you will need to update your rom that incloded the update via cmw recovery

Hmm ok
So you loose recovery too? I thought you would only loose root?
But arent the last two posts exact opposites? One says you would get ota and it would install but you would loose root and recovery and the other says you would get ota but cannot install it. Or am i missing some point here?

OTA updates install fine with CWM and have for some time. The only reason it would fail is if it is trying to patch recovery and does an assert.

You will lose root on incremental updates only because it does a recursive chmod on /system - so it just changes the permissions on the su binary.
You will lose your custom recovery because it will restore /etc/install-recovery.sh which restores the stock recovery on boot.

not to smash your topic to bits but SINCE WHEN has an ota update been available before aosp code? Welcome to nexus device people running stock is for chumps you won't need ota updates because you will already be on a custom rom that has it

The Froyo source did not push to AOSP until after the OTA to the Nexus One.
Slightly different but also held from AOSP until out on a device:
Eclair (2.1) was not in AOSP in a form that would build for a device until post Nexus One being available.
Gingerbread did not push to AOSP until after the Nexus S was available.
The other hold up is when new binaries are needed for the build. The early AOSP Gingerbread builds for the Nexus One were BUGGY.
The ICS builds for the Nexus S needed some "shady, leaked" binaries to get things up and running well (wifi, bluetooth, GPS, etc).
Typically the new binaries are not posted until it OTA's.

You can say this all you want - I've run stock rooted roms on both the Nexus One and the Nexus S without any issues. The Nexus S forums are filled with people with issues with spontaneous reboots, poor battery life, FC's and 95% of the time it tracks back to a custom kernel that has been "tweaked" or the ROM they are running.
If you are looking for the added features of some custom roms then go for it. But thus far pure AOSP builds have been anything but "for chumps" with the Nexus One and Nexus S.

I'm pretty sure but "custom roms" he also included builds made from AOSP. The point is that AOSP is often newer between bigger releases and the times an OTA build is newer you could always just flash that if you really want.

Ok thank you guys
I learnt much from this
So in fact if i go cwm and root my best option is to forget ota and go custom rom. Even if its a stock + root custom rom.

You can't receive OTA when your device is rooted. Why? Every OTA checks system consistence. If some different files or the same files with different checksums will be detected, OTA will be canceled.

[Q] Help about rooting and other stuff

Sorry if this question has been asked before, but i could not find any.
So i got the Nexus beast yesterday, and it's already blazing me off with it's greatness. But i got a few problems though:
1. I got the jakjuxw, not the jakju, will i get the same updates as the jakju OTA, but only a week later or so?
2. I did not root the phone before starting using it, but i regret that now. Is there any way i can root it and NOT lose all of my apps and data? I have spent so many hours to customize this device and i dont want to start all over (yes i know about app backup's, but they are slow)
3. If i root but stay with the stock rom, will i still be getting the original OTA updates or does i have to flash the roms manually and wipe the phone every time?
I'd appreciate it if anyone could answer all the questions =)

Not sure about this, it probably depends on what they want to release. I don't think there's any kind of guarantee they'll get the same updates, but there's also probably no reason why they wouldn't.

You need to unlock the bootloader to root, and unlocking the bootloader wipes the device. Sorry. Someday an exploit might be found for ICS that allows you to root without unlocking.

If you keep stock recovery, you'll still get OTA updates when rooted. If you use custom recovery like ClockworkMod, you'll have to do them manually (but you won't need to wipe). In both cases, applying the update will probably cause you to lose root and you'll have to re-root. This is easy if you've unlocked the bootloader.
If you root by using some future exploit, you might find that the update you just installed removed root and closed the hole that allowed you to gain it without unlocking the bootloader, and now you're left stuck without root. I'd say just unlock the bootloader now and be done with it. It'll be a pain, but then you don't need to worry about it again.

Yes, but the updates will probably unroot you. You should be able to just re-root after. If using CWM you can probably flash superuser right after flashing the update and not lose root at all. This is what I always did with my Nexus One when I still had the rooted stock ROM.

If the ROM comes as images (like the Google factory images) you can flash with fastboot. The Google ones come with a script that uses fastboot to do it for you.

I meant installing updates here... you don't usually need to wipe if you are installing updates to your current ROM, such as OTA updates to the stock ROM. You need to wipe if you're changing ROMs. It's probably no different than your Desire.

After rooting, will the OTA work?

I am sorry if this question is answered already, but is there any way one can get the OTA again once the device is rooted? I mean by unroofing and factory reset or whatever means....

After rooting, OTA is still working but you'll probably lose root after it, excepted if your Superuser has an " OTA Survival " feature. In this case, you'll have to flash a stock ROM, and root it.

be careful if you have a custom recovery, accepting an OTA might screw your device up.

Will the custom recovery be overridden by the stock one? Or is there any chance of bricking the device?

no sometimes what happens is the files dont install and you either get a reboot screen or some sort of black screen and then you might need to fix things with a toolkit through the pc or some hard kind of fix, t happened to me on a motorola Atrix a while back.

If your phone or tablet is rooted but with Stock Recovery the OTA should work just fine as long as you haven't modified any system files that get updated through the OTA. The bigger the update is the more likely it is you will lose root and that the OTA will find modified files. On Nexus devices I've personally never seen more than an error message if the OTA fails. At most I've only ever seen "unexpected contents in" error with whatever (modified) file is the problem. The OTA will always fail if you have a custom recovery but it's not really a big deal, you can always flash the OTA update zip in your custom recovery (TWRP?), more often than not before the OTA even rolls out to your device you can find the OTA zip here or on another website.

[Q] Question about root and updates

Lets say I want to update to a new version (Android L) when Samsung (if they ever bother) deploy it, I want to know if OTA will still work? I am only going to remove bloatware not flash any other rom.
Add to this I can't boot on download mode... it keeps looping the boot screen.
Thanks in advance.

AFAIK OTA doesn't work once you have rooted

That's not entirely true. Specifically rooting does not block an OTA but usually you'll loose root when an OTA is applied. SuperSU includes a method to preserve root through an OTA. The reason most OTAs cannot be applied after rooting is because they check specific apps and if any have been tampered with or are missing the OTA aborts. Of course most of the reasons that you root is to "tamper" with the stock ROM so it's a catch 22 situation. You could root then add an app for some specific functionality and still apply an OTA.
