Rooting to upgrade to latest firmware for S2

Hey guys complete amateur at this and couldn't find a clear answer for the issue I'm having. I have an unrooted Galaxy S2, in Sri Lanka.
I believe that my carrier doesn't allow us to get OTA updates as I'm currently on 2.3.3. I've heard that there have been a few more updates since. Was just wondering would it be possible to root the phone and then upgrade to the latest Samsung firmware without installing any ROMs? Just want to break the carriers hold to receive OTA updates from Samsung is all I'm looking for? Is this possible? If it is could someone please point me in the right direction, would be much appreciated. Thanks.
You can install latest firmware without the need of rooting, just grab the orginal firmware (samfirmware.com) and flash it with odin.

Flashing orginal firmware via odin dosnt ask root, and dosnt void your warranty.
Thanks, sounds like the perfect solution!

[Q] From custom to stock firmware for OTAs

Hi, I have a Samsung Galaxy S2 on the three network. If I flash the H3G 2.3.3 firmware to the device using Odin will the OTAs still work? If not is there a way to flash the standard firmware back and have the updates working as normal?
Thanks
If you flash stock firmware for your region, you should be able to get updates OTA again. In saying that, I've seen more than a few cases where this hasn't been the case (Why ? No idea. Never happened to me/not important to me as I don't use stock firmware so I've never delved into the why).
So you can flash stock firmware, see if you can get OTA updates.
If not, might as well take the easy course & flash your stock firmware updates via Odin (like many people) rather than spend potentially who knows how much time trying to find out why OTA won't work in spite of you going back to stock
It works for kies and OTA
I downloaded the original 2.3.3 and flashed it to my Samsung Galaxy S2 and the OTA updates worked up to firmware 2.3.5 and then I plugged into kies and it updated to 4.0.3. I used this site http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-I9100&r=-1#modelsa
Thanks for the help guys.

[Q] I need special help with my Phone :(

I bought htc one m8 from e-bay (at&t unlocked) when I was USA. That at&t apps are really annoying and I didnt get the lollipop update. I wanted to update the rom by myself and delete the at&t apps. And now I rooted + unlocked bootloader and installed android revoulation 5.0.1 lollipop rom. I can't use wifi + I cant reboot the phone (it stucks at white HTC screen). I didn't flash firmware because s-on still. So I need really simple and detailed information about what to do. Can anyone pm me about it or explain in comments?
There is not Lollipop update for AT&T yet.
And if you aren't on AT&T's network you won't get any OTAs either. AT&T is fairly unique in this regard, other versions will update regardless of what carrier you are connected to.
For most Lollipop ROMs, you will find your WiFi is broken due to wrong (old) firmware. Your options:
1) A couple Lollipop Sense ROMs (LeeDroid?) seem to work with 4.4.4 firmware. But if your firmware is older than 4.4.4, I don't think any Lollipop Sense ROMs will work.
2) Revert to a ROM version that supports your firmware. For instance, if you are still on 4.4.4 firmware, install a stock or custom 4.4.4 Sense ROM.
3) S-off and update your firmware "manually".

Flash official Lollipop 5.1 without unlocking BL and root?

Hello to everyone!
My sister has a Moto E 1gen and she's still on 4.4.4. I wonder is there a way to flash new Brazilian 5.1 Lollipop without rooting the device and unlocking it's bootloader? Maybe something like flashing FW via Odin for Samsung phones or Flashtool for Xperia ones.
Thanks in advance!
Still not got OTA?
Download the correct 5.1 OTA for KK 4.4.4 and put the file on sd card, go to about phone > System updates and check for updates.
The only 5.1 image for XT1021 I've found is Brasil one. I think I need Retail Europe version. Could you provide me any links?
There is no official Retail Europe yet
So maybe 5.0 or 5.02 Retail Europe instead of 5.1?

Question Flashing newer firmware on an unrooted XQ-CQ54

Hi all,
I wanted to flash a newer android 13 stock firmware because my Sony from a UK operator doesn't get the OTA update.
I have the firmware from XperiFirm and made the ftf with flashtool. Just before I was about to get if flashed I was reading comment saying this tool is not good anymore, but I am not 100% sure how to use the Newflasher instead.
Could someone help me on that?
I don't really want to brick my phone and if it's not a safe way to get android 13 I might just don't do it.
Cheers.
