Hello all,

[Q] Doubts with my SGS2

well these are my questions, i'm looking for some answers i'm sure you can help me or erase these doubts i have.
Phone info:
Unbranded phone bought in USA and used in Argentina (sorry for my english, not really good)
Gingerbread 2.3.4
PDA: i9100UHKI2
PHONE: i9100UHKI1
CSC: i9100TPAKI2
i got my phone 1 day ago the first thing i did was a cf root kernel and my phone was root then i got speedmod kernel and everything ok (So only kernels customizations) but here is my doubt
1) Can i flash any kernel i want? I think i can, but.... haha
2) can i flash now any custom rom i want, for example villain, litening, etc
IF i can, will i have problems with mi 3g network. All the explanation with the csc is not clear on my head (or maybe i can put manually my apn settings, or flash a csc unbrandeed thas my stock rom has)
3) can i flash between any stock rom or this is not recommended
4)if i can flash any custom rom like villain, that custom rom is 2.3.5 and my phone is 2.3.4 is that a problem or not. maybe i need to flash an stock rom 2.3.5.
I have made efs backup, cwm backup, and my stock firmware is on stock firmwares thread so great
that's all thanks in advance guys
this forum helped me a lot.
PS: i have read al the noob guides and faq, and searched on the forum but truly i didn't find my answers and my english is not good enough haha so it's get complicated sometimes to understand clearly the idea.
im not expert but i can answer few of your question..
1. yes u can ( btw u didnt have to root ur phone at all.. since speedmod comes with preroot)
2. yes u can flash any rom u want but some roms isnt compatible with some kernels so u should read carefully which one is compatible
3. im not entirely sure but i think u cant... because different stock roms have different csc which is ur region data... i live in finland so i can only flash nordic roms.. but as i say before not entirely sure
4. about this i have no idea =/

Yup, you can do all of these. I installed cf-root on my own SGS2 aswell and went straight for custom ROM's (im still staying on the cf-root (stock with root) kernel. Didnt need a new one, but it doesnt matters you can do anything anyways).
As long as the rom/kernel you download is for the sgs2 (the clear one, not at&t or any other), everything will be perfectly fine.
As for the 3g problems, just try the rom out (or read feedback/ROM desctiption)

Oh and about question 4. Yes you can, its just like updating from 2.3.* to any other. I was on stock 2.3.3 and jumped straight to the Revolution ROM which is based on 2.3.5

I never had problems with csc. Never even touched it. Just flash the ROM's and thats it
And about connection, you should simply get the Modem that is suitable for you after flashing the ROM, but thats not a problem

[Q] Help! How to remove CWM from S2

Hi,
I just got my Android and happened to Root it with a firmware containing CWM because I really had no clue as to what it was. Now I would want to be able to remove this icon CWM from my phone. I have tried flashing the kernel to no avail. Please help me with a step by step procedure to remove it since I'm absolutely new to Androids. My S2 runs gingerbread 2.3.6. I did check the web but am so confused with all the options provided.
Thanks in advance.

It is strongly recommended to back up stock ROM before u give try to Custom ROM.
*#1234# - Check your Firmware version before u do Rooting and make a note some where
You can use those information to download your STOCK ROM from many website (google them)

Since you are rooted, use any file explorer with root access and delete the cwm manager.apk.
Second option is use root un-installer and uninstall the cwm manager

Simple yes, but you want him to flash whole ROM instead of removing one file.

in some Firmwares CWM is included in system applications, so cant simply uninstall it, you can use Titanium backup application to uninstall system apps,
But before uninstalling better you learn more about Rooting and the functions of this app and other root apps. This is a very usefull app in the rooted and Clockwork mod installed devices, for rebooting into recovery easily, kernel flashing, backing up of the Rom ect..
you can have informations from below sticky thread as well as from my signature links.

Thanks guys for your prompt responses. I will try and flash the stock rom and let you know if it work. Thanks again

I installed CWM to test some custom ROMs on my device. What if for some i reason i have to take my mobile to service center.
Will they charge me (even if my device is under warranty) because i have installed CWM?
Do I really need to remove CWM? If yes, how??
Do you have a 3rd stupid question to ask?

Yes you will need to remove root so flash Sam firmware with mobile Odin and don't root. Now back to stock. :thumbup:
Or send it in and report bk

It would be very helpful if you can provide a link for reference

Thanks for replying andrewwright!! (you too "theunderling"!!:angel
I haven't actually installed CWM yet and came here to clear my this doubt.
Why Sam Firmware (if Sam = Samsung) while my device is XOLO q800? Can I take a backup of my my stock firmware in some way because XOLO is not a popular brand and I won't get much support(stock firmware) over internet.
Also, I read somewhere that particular firmware corrosponds to a particular chipset(mine is MT6589), is it true??
I would really appreciate if you can provide a link for reference where I can read further or otherwise some people will keep yelling here "noob......noob"

So many Tutorials & ROMs..

Hello guys,
So, I decided to install another ROM on my Samsung S2 i9100G - thats why I went to different forums and found so many ROMs and Kernels and Tutorials, that I'm not sure, which one to use (and where the files are up2date)
Ive got a German Model with 2.3.6 (I9100GXXKL4)
and my kernel is on 2.6.35.7
I'd like to use CyagenMod (dont know the exact name) 4.0.4 on my Phone and I already downloaded Odin - but "damn" im scared as hell to brick something with the wrong version lal (I flashed my nokia 5800XM and it was a hell of work )
and do I need to install any kernel? where is the difference between the ROM and Kernel? can I just install a new ROM?
greetings
se7Ro
edit:
DO I need to ROOT my Phone?
and: Is a SD Card neccesary or can I use the phone one which is integrated (16GB)
Third Question: Can I use any Kernel I want? As far as I know now, I need to Root my Phone flashing a Kernel via Odin (I will use Lucifr)
But its a GB Kernel, right? So I cant use any ICS ROM?

If you don't want to root go to www.sammobile.com and pick a ics firmware. They have flashing tutorials. But honestly I wouldn't do anything until you do some research.

Before you do anything to your phone, DO NOT INSTALL A I9100 International firmware.. You have a I9100G, It is not in anyway compatible to the intenational phone. READ THE STICKIES FIRST PLEASE.

If u mean that XXLPQ is only for international sgs2 uare wrong read that topic here
Now
I have got plan: buy those thinks bla bla bla
Then here download flash rom what ever wich rom
Then use this to instal CWM recovery and get root.Its very important beacuse without this u wont get CM9(Cyanogenmod9).Now go to CM9 thread
And install CM9 (dont do ''proper CWM (ClockWorkMod)" beacuse u was doing this while rooting

Thanks,
Your posts arent very informative either.
1.post details about phone.
2.if you want an unbranded stock firmware........then say so
3.read threads about noobs

No reply like always :/
You need to root your phone first mate, then you'll be able to flash custom ROM's through the recovery.
Look around this forum or google to find a root for your phone.
