[Q] New android user, I have a few questions - Galaxy S II Q&A, Help & Troubleshooting

Hello everyone!
I have a rooted galaxy s2 (I see the superuser app on my phone) running android 2.3.4. This is a Bell phone. What I would like to do is unroot the phone, then update it to 2.3.6 or wtv update is available through kies (normal update) and then root it again and unlock it using Galaxy_S unlock so I can use it with Fido.
I have a few questions:
Is it even possible to do this?
Can anyone tell me if this is a good method? how to do it properly? or any better alternative methods?
also, if I use this unlock, is it permanent? or do I have to re-unlock the phone every time I loose root/update firmware
ANY help is appreciated, i'm trying to put all of this together and it's not very easy. I bought the phone rooted...but it's not unlocked (as it doesn't work with fido), needeless to say I have no clue how it was rooted and what was used (or if it even matters).
EXTRA infro: (when I press *#1234#, I get:
PDA: I9100XXKG6
Phone:...XXKG2
CSC:...OXAKG

Tell me 2 things, why do you need 2.3.6 and do you have an app called CWM on your phone? The icon looks like a gear

1. first unlock your phone, it is permanent you do not need to unlock if you flash again.
2. you may not be able to use kies to update as the kernal which kies uses to update was changed when it was rooted.
Do you perfer stock or custom firmware ?
you can get the latest stock firmware and installation guide from this thread.

if you want custom search in Android development forum.
3. you will lose your rooting when you update firmware. All you need to do is reroot your phone it is easy. follow instructions in this thread.

[Q] Unroot 2.3.5 Firmware?

Is there wany way to unroot Android 2.3.5 on the Sgs2? I followed this guide:
(Google "samsung galaxy s2 android version 2.3.5 root", Top link).
The only reason why I rooted it was to calibrate the battery, now that that's done I want to unroot. I restored the stock kernel that came with 2.3.5 but still no luck, CWM and Superuser still stay there, with no way to removed them. Thans.
you need to flash the astock firmware to remove root not only the kernal.
there is another way to get rid of the root, use SuperOneClick v 1.91, and click on unroot to remove the root.

[Q] do i have a rooted phone?

Hi there , hope someone can clear up this for me.
my phone was bought second hand , galaxy s 2 unlocked to any network,
the PDA : I9100XWKE1
phone : I9100XXKE4
csc : I9100XEUKD1
it shows its running android 2.3.3
kernel version 2.6.35.7-I9100XWKE1-CL181974 [email protected]#2
i only ask if its rooted already as it says there is an available firmware update , but i cant do ota or through Kies, when i try it says my phone cannot update . i want to be able to update it but ideally not through rooting. ( not confident enough to do that , i'd probably brick it and cant afford to replace a £300 + phone .i owned one previously which i bought from carphone warehouse and was unlocked as i was able to upgrade ota and through Kies . so at a loss here many thanks if you answer .
Install an app from the market which requires root and see if it fails to run.
Or install root checker from the market

just installed something called root check basic which says i dont have root access , so i guess i dont have a rooted phone but am at a loss as to why it says there is a update but wont let it happen, have googled all this and there are other people out there who had identical info to my phone but sadly they too are still in the dark .
Maybe your phone has just been debranded that's why your unable to do updates via Kies, you could ask the seller what carrier the phone was on when they bought it but if I was you would just use odin to flash your roms things come out alot faster on here than Kies.
from your information given i'm pretty sure you phone is not rooted, he/she probably debranded it or installed a different rom for it
What baseband version did the phone came with? You can probably download the Stock ROM that came with your phone and get back to start

I take it your not comfortable with using odin? Sounds like you might have to flash the original rom via odin or root via cf and install a custom rom via cwm. There's plenty of good guides and people to ask if you've got questions. The cf thread is a good place to start http://forum.xda-developers.com /showthread.php?t=1103399

I found it easier to just flash a ROM with root access already on it. (Lite'ning in my case) That way you then have root and clockwork, which you can then use to flash whatever ROM you so choose.
I just thought it was easier that way instead of having to do them separately.
Don't worry though, I'm sure my dog wouldn't even have a problem flashing a custom ROM via Odin for the S2. It's as simple as pointing Odin to the directory of the desired ROM, make sure no additional boxes are checked and away you go.
= What are you even doing asking whether or not you should root your phone on XDA?! =
ok i have downloaded odin and am downloading I9100XWKE1_I9100XXKDJ_I9100XEUKD1.zip XWKE1 - GT-I9100 which appears to be the latest official uk firmware. got the guide to using odin and will start tomorrow when i finish work. i understand this just updates the firmware. i assume doing this will still mean my phone runs all ok . do i have to root ? i really know bugger all about stuff like this ,

How to update rooted phone ?

Hello
I had rooted my S3 few days ago with this tool SAMSUNG GALAXY S3 TOOLKIT V1.0 so my phone has now root access a CWM.
Modem version I9300XXLEF
Number version IMM76D.I9300XXALEF
But notification said that there's new update available - 8,91MB installation brakes after restart cause lack of some signed files, is it possible to update my phone now but without erasing any data ?
I have found latest firmware here Samsung-Updates.com-GT-I9300_XEO_1_20120612172415_pax5uhw4id.zip XEO for Poland but don't want to loose any data from phone
Which tool should I use and what files should I use ?
Thank You for any help.
If you want to go back to stock rom why don't you use the Toolkit again? It's pretty straight forward.
Just flash the latest Firmware via CWM if you want to update.
thread: Official Stock Firmware (up to latest)
back-up via Titanium Backup if you don't want to lose your data

I'm still on stock ROM but rooted and with CWM, so there's no way just to apply modified update, or to unroot it with stock bootloader just to do an update and then root it again with CWM ?
@bordikun
Yeah, I have read it but it's full firmware/ROM if I understand it correctly, I got Titanium Backup and use it but just feel that all this is just an overkill, so many procedures just to update 8,91MB of data ?
have you tried there ?

[Q] Can't have OTA, craving for ICS

Hello,
I am using a Galaxy S2 (I9100) running Android 2.3.3 that has been rooted with the zerglings method (the one with busybox where you don't use ODIN and just execute the batch file from your computer). I am currently stuck with a wireless mobile broadband connection that wont let Kies update (Gets stuck at "preparing firmware upgrade components"). Yes, I am using the latest Kies and have tried on a different laptop as well.
Now that I cannot have the official update from Samsung, and since I already have lost my warranty, what is the safest way that I can use to upgrade to ICS? And in case I end up bricking it, can I recover it?
Another reason why I am a bit unsure is that I don't want to lose root. I hope I'll be able to retain root and other installed apps (like Droidwall, ES File explorer etc.)?
Regards,
Sayak
Regardless of what upgrade path you end up taking, you will lose root. Sorry.
As long as you find and use a firmware meant for your exact model phone, there is no danger in flashing a firmware with Odin. (unless you do something weird, like unplug the phone or your computer loses power in the middle of the flash or something)
There is a thread on this forum with all the stock GB/ICS roms you need. (Look and you will find).
All you do is flash which rom you need and if you want root simply flash a custom kernel via odin like Siyah.

[Q] GT-I9000, failed rooting, how to get back to 2.3.6?

Hello all!
I am a really n00b with rooting and cutom ROMs and I wanted to try this with my old Samsung Galaxy S (GT-I9000) phone. Of course it failed and I managed to brick my phone but after lot of searching and trying I managed to unbrick it After this process I ended up with version 2.2.1 and I would like to know how to get back to version 2.3.6.
This is what I have done so far.
1) I updated my I9000 to version 2.3.6 using Kies.
2) I rooted my phone with CWM but I think that I used too recent version of Odin and got to bootloop.
3) After many tries and scouring the web for information I managed to unbrick my phone.
4) Unbricking ended up my phone being of version 2.2.1.
5) After some tries I managed to connect my phone to Kies again as I wanted to get my phone back to version 2.3.6 but Kies said that my phone was already up to date.
Now I don't know how to proceed.
I wanted to get back to 2.3.6 preferably with stock ROM as I read that after that it is much less risky to proceed to version 4+ than if I tried to do it straight from version 2.2.1.
Any and all help is greatly appreciated.

Just need to find the file for 2.3.6 for your phone and region and presumably just like you did for 2.2.1. Use Odin 1.85 and put the firmware file that is in .tar or tar.md5 format into the PDA slot.
You can go here: http://www.sammobile.com/firmwares/ and search for your phone and download the appropriate file. There might be a quicker download mirror in the XDA forum for your phone.
