[Q] what will happen if updated while I'm rooted - Galaxy S II Q&A, Help & Troubleshooting

I'm on custom And I'm rooted
But I just got an system update
What will happen if u downloaded it and installed it?
Sent from my GT-I9100 using xda app-developers app

If the update has a new stock kernel (probable), you'll lose root. Easy fixed tho.

Custom recoveries will usually cause the ota to fail.
Losing root is another common result. You can also have a lot of funky things happen like the update will go halfway through and then fail, and that's pretty messy.
I would highly suggest waiting it out for your devs to build it into their ROM

[Q] updating to EH04 on lightspeed rom lte

Kudos jfl0wers!
Just flashed on about 15 min ago. Runs great and seems snapper. Only problem is Im being prompted to update to EH04. Before all I did was flash stock recovery and kernel and I was able to update to EH04 with no problems other than having to reroot to get superuser working again. Any suggestion as to how to update to EH04 on your build or at least get rid of the annoying notification. Just to provide some info I currently have the updated EH04 baseband and obviously the EG01 software build.
Thanks again for the first LTE ROM! Great work!

Where did you find this rom? It is not listed on the android development. Where did you find the stock recovery? Are you using CWM for recovery?
I am working on getting updated. I will supply an update with EH04 as soon as possible.

New to Root, one question.

If I root using CWM, will it wipe my phone or do they only suggest backing up in case the root goes wrong?
Thanks in advance.

If you root by flashing the chainfire cf kernel you wont lose anything. It really just changes to a rooted stock kernel. Is it cf root you want to flash?
Sent from my GT-I9100 using XDA
I guess so. I just want root access to remove Three's bloatware apps and improve performance and battery life. However, rooting means I can't update to official ICS right? Or wrong?

[Q] Official ICS Update Removes Root?

I just used Kies to update my Samsung Galaxy S2 I777 from 2.3.6 to 4.0..3 ICS that just came out. I was previous rooted and now the root seems to be gone. How do i fix this and root my phone again while its 4.03?
Does the super 1 click root work on the official 4.0.3 version?
I would appreciate any help/directions on how to reroot my phone after i updated to the official ICS from AT&T. Thank you!
You can not root the official update

So I'm stuck with this forever or will there be a fix for this in the near future?
Btw was it normal for my root to be removed by updating my phone using kies? Because when i updated previously from 2.3.4 to 2.3.6 OTA using my phone's software update option, it didn't remove the root. I was surprised to see that ICS did
Also, what do you guys think about using this method to root my official version of ICS 4.03 on my S2: http://galaxys2root.com/galaxy-s2-root/how-to-root-ics-on-att-galaxy-s2-sgh-i777/
I know most people on here don't like galaxys2root.com but I'm running the unrooted version of ICS from galaxys2root.com and am having no problems.

Yea but i want to root so that i can freeze apps using titanium back, as well use root capabilities such wifi tethering and root explorer. So i need to root soon. What is the best/safest way to do this on the official ICS 4.03 version?
Well I don't know why his rooted version would be good as well...have you read the comments on his tutorial in the link you posted? Probably will give you a good idea of how it's going for other people.
Sent from my SAMSUNG-SGH-I777 using XDA
It seems to be working for some people but I honestly don't want to have to root using a I9100 version/kernel to have a root. I was hoping that there was an similar root to the super 1 click root method where you can keep your phone on the i777 version.
Also some of the comments say that they are having issues with certain buttons, and on the youtube video one comment says something about getting bricked. So idk
Restore to stock kh7 with root, then flash the official rom in the dev section is the only way I know of at the moment

My humbly tendered suggestion would be that you start reading here: http://forum.xda-developers.com/showthread.php?t=1313659
Oh, man...why won't someone spend the time to find this poor guy the info he needs and post the links? It's not his fault he did an update without first knowing what effects it would have on his phone. What a heartless bunch you guys are. It's not like he's been here for over 3 years and knows how this forum works.
Yes you can root the update but trying to flash an update script thru 3e recovery didn't work for me and will format your sd card when you exit 3e but I was rooted within 10 minutes after upgrading to att official ICS. Just to be sure I downloaded/installed Superuser and busybox, then I flashed the CWM recovery kernel ( if you don't know ahead of time how this process works please research before attempting it) which won't boot the phone but allows you to use the button combo to get into recovery and then flashed the latest Siyah kernel .zip (or whichever ICS kernel you prefer), which had been strategically placed on my sd card prior to the Kies flash. And voila...root and recovery.

Why not just flash the pre-rooted version?
...and then there's that ! ^ As a matter of convenience that works too...but personally I like to take what I've learned thru these forums and apply it in real life to retain the process.

Another way to do it, if you have the Odin flashable files, would be to use Mobile Odin with the everroot option checked.

So does this look just like the "official" AT&T release (just cleaned up)?

Help CF-Root

i want to use cf-root in my Phone, but before i do it, I need to now if this will erase my personal data...
Thanks for the help.

No it won't

dr.m0x is right. it won't erase any personal data ... The only thing it does is (as far as i know) install a different kernel and install a different recovery program.
PS And btw it also installs the programs SuperSU and CWM
One question about this: is it true that I can't get ota updates after applying cf root? Instead I have to flash them with odin?
Sent from my GT-I9300 using xda app-developers app
There may be a problem with OTA updates, if they work your device will probably be unrooted though so you just have to root it again

Well if you having this problem with OTA, you can always update via Kies which was working fine for me. I was in XXALF6 and rooted and managed to update to XXBLFB via Kies, but all modification, root and custom kernel gone.
Thanks for the help...

Hi, if you are doing OTA it will be 4.2.2 or 4.2.3 at best, you will loose root, but not files or data.
Some apps may stop working or work differently, nothing to worry about.
Thanks and hows that? Major improvements? Something always weird with this one was the greenish tint when shooting with the flash... Is that fixed?
And there is a new chainfire's root out there i guess....
Thanks

Just want to say this isn't correct. Don't know if it's mistyped or something else, but it should be 4.1.2 'at best'.
Last official (thus OTA available) update for S2 will be 4.1.2. Sad as it is, for today's standards it is still acceptable.
what do you guys think about the 4.3 like sentinel rom?

4.1.2 is the latest (and last) official Samsung update. There are 4.2 and 4.3 roms available, but those are custom ones.

Yes i was wrong, long time didn't have to use stock.
As for ROM selection, try PAC rom, (latest nightly 4.3.1) I am really happy with this rom as my dd.
thanks guys, I am about to upgrade, just a question, can I use the OTA update even if my phone is already rooted and I have Siyah kernel on? is it going to break or get stuck?

The OTA will probably fail.....the OTA package looks for a stock setup, and if you've modified that setup in any way (custom kernel) the OTA won't install.....even if it *didn't* fail, the kernel would be overwritten and you'd lose root.
If it were me, I'd make use of chainfires mobile odin, download a jb firmware from sammobile and update that way......

Did you enable the 'ever root' option in mobile Odin?
If not, you'll have to root the phone afterwards (if you want to)
A good place to start is the PhilZ kernel (rooted stock kernel + touch cwm)

cheers, actually no ever root since I used the lite version eh eh... I just rooted with this method w/ Siyah Kernel. worked like a Charm... now I guess I will be busy customizing it.. it seems much faster between home screens I have to say!
thanks again for the help
Gab
Yeah....I guess that's 'project butter' or whatever it's called....it's supposed to give an overall smoother performance........
If you are going to stay with stock, my advice would be to 'de bloat' it.....I used Titanium Backup to freeze the bloat first, then delete it after I'd found out that it wasn't needed/critical for the phone to run.......

The thing that I hate the most on stock rom is that it drains battery too fast
