Hi everyone,
I'm trying to flash a Samsung Galaxy S2 I9100 running Stock Android v.4.0.3 on Baseband I9100XXLPH.
I've searched a lot of threads but it seems that over the years there are 5 billion ways on how to root, install CWM and flash a ROM.
I'm not a 100% noob in this area as I successfully unlocked, rooted and flashed my HTC One X lately but:
Could someone please tell me the easiest way of rooting, installing CWM and flashing CM9.1 using the latest tools out there? Please also let me know on how to upgrade the Firmware if thats needed. I tried using Kies already but It keeps telling me that the device doesn't support that. And if someone could explain to me what a insecure kernel is compared to a original one, that would be fantastic!
I've already tried flashing CWM 5.8.1.5 using the standard samsung recovery but once I select "apply update from external storage" and select the CWM zip it starts CWM but after one reboot its gone again. I can repeat these steps everytime I would need CWM but isn't it supposed to replace the default samsung recovery?
Thanks in advance!

Hi!
If you want to flash firmwares, here's how http://androidflip.com/how-to-install-flash-firmware-on-samsung-galaxy-s-2-gt-i9100/
But you're on XXLPH, so I suggest you use this guide to root: http://www.androidauthority.com/root-xxlph-on-galaxy-s2-i9100-using-cf-root-kernel-54416/
and that'll get you started somewhere..
Here's the index of guides for our s2: http://forum.xda-developers.com/showthread.php?t=1826497

I know it's been adressed many times in different ways, but the info I found yet is not clear so I need a little help! I am trying to install the latest stable Cyanogen mod, using Gingerbread 2.3.7.
I have a Galaxy SII from Bell that I rooted and unlocked when I got it last november. It came on 2.3.3 and I flashed an official 2.3.4 on it, mainly to improve the battery life (and it worked). I did that using Odin and it went well.
Now I try to install Cyanogen mod through ClockworkMod ROM manager, I download and launch the install from ROM manager but on restart the install fails because of the classic 3E recovery message that says the whole signature cannot be verified.
I was having doubts if my phone was even rooted, but since it is still unlocked and software like Titanium backup runs fine, I guess that confirms it!! I am not sure what route to take from here...
Right now here are the phone details...
GT-i9100 on 2.3.4, FW I9100XXKG2, Kernet 2.6.35.7-I9100XXKG2-CL375027 [email protected] #2
I'll appreciate any help!!!!!!

Thanks jje... The instructions did work! Tough I tought I had bricked my phone at one point, on the final restart it would get stuck at the Samsung logon screen, but I forced it back in recovery, re-flashed from the zip and then it booted in CyanogenMod!!!
I really appreciate your reply
Hi,
I am unsure about how to flash a ROM on to my phone.
I have already rooted it and installed a insecure kernel using Odin and the Samsung Quick Root tool (found here: http://forum.xda-developers.com/showthread.php?t=1125414). :victory:
I am still running the insecure kernel that I flashed with Odin, and did not install CWM as I do not know what to do.
ROM Manager is installed on the phone but I don't think CWM is actually installed.
Currently, I want to install the F1 Galaxy Nexus ICS ROM. (http://forum.xda-developers.com/showthread.php?t=1601518)
All I want to know is do I need to install CWM, and how to install and flash the ROM to my phone.
The exact model of my phone is i1900-XWLPI.
Thanks.
Hi.
Yes you need cwm.
How to install Rom always be a guide in thread...
Send form Galaxy S2. Using XDA Premium
I was following a guide on it.
Now I am worried
I think it is bricked as it is stuck on the yellow triangle screen.
I don't have a jig and I NEED IT WORKING.:crying:
Ok I managed to get it to go in to d/l mode and flashed kernel back to the one I had earlier.
I think I'll just leave it for today and try another time.
Too much happened today and I don't want to risk a permanent brick.
just as it says im new to samsung not to android, my question is i followed the root guide and can get to the recovery screen but everytime i try to flash a rom it fails to install the rom, did i do someting wrong in the rooting prosses? i have the samsung att i717

you do have an alternate recovery, right
most likely very simple...............is it a STATUS 7 ????
if so, you just need to update your recovery.
if you are using CWM, many ROM's suggest TWRP. some are not having problems with CWM, but TWRP is much more user friendly and don't have to mess with vol +/- buttons
You don't need to be rooted to flash a rom.
Either flash from the phone using a custom recovery like ^^^^^ described, or flash from a pc using samsung software (Kies or Odin3).
All custom roms are rooted by the developer.
You know YouTube helps if you think you are having trouble it shows you how to do it.
Hello,
I recently made some mistakes with my Galaxy S2 GT-i9100 while following this a tutorial on Galaxys2root.com (Can't link to the precise article because this is my first post) I flashed the CWM recovery tool linked by this website to my device through the latest version of Odin and afterwards my phone would not turn on. I was able to get into the Clockwork recovery mode however but couldnt install anything because I had forgotten to place any ROMS on my device beforehand. To try and resolve the problem I did a factory reset in the recovery mode but this did not effect anything. I am now unsure what to do next. I would still like to root my phone so that I cant get rid of all the bloatware put on it by Orange mobile as well as update my phone to Kitkat(Currently running Android 2.2) Can someone tell me what I have done wrong and what is the next step for me to take?
Thank you for any help that you can offer
the kernel you flashed it is the problem

is this site you are talking about:
http://galaxys2root.com/cwmtwrp-recovery
im guessing that is the problem(Installing CWM/TWRP recovery will most likely break the ROM you are running currently as it overwrites the ROM’s KERNEL).
If iam right,that means you have to flash another kernel,i suggest Siyah kernel 2.6.14 its for gingerbread version(it has CWM recovery and auto-root):
http://forum.xda-developers.com/showthread.php?t=1263838
after that you can flash the KK rom you want through CWM .
Hello dear community
This is my very first thread I am making on this website, so please pardon me if I am on the wrong page of this website.
Anyways, I'm more or less desperate. I saw a youtube tutorial on how to install Android 4.4 Kit Kat on a Samsung Galaxy Note N7000 and I heard I'd need root AND a custom recovery.
Because I'm a total newbie to this kind of stuff, I tried the very first thing I saw that had something to do with custom recovery, because I already had my phone rooted. So, I looked up a tutorial on youtube on how to install CWM custom recovery and ended up with installing it successfully, but now my phone is stuck in a bootloop. As I already mentioned, I am a newbie and therefore I am very desperate at the moment, you know.
The only thing I can do is go to Recovery Mode, but if I try to turn the phone on it gets stuck in a bootloop (It actually doesn't loop at all, it just freezes at the moment when the Samsung Galaxy Note logo appears and doesnt do anything after that.).
I think my problem is that I actually threw a new Kernel on my phone, because the video title says "How to install Kernel with CWM [...]"
I would be very very very very very grateful if anyone was kind enough to help me get out of this!
I really need help!
Thanks!
PS.
If this helps you help me:
This happened when I had Android 4.1.2 installed.
There's going to be 2 ways to get out of this:
1) Reinstall the stock firmware via Odin.
2) Install a custom rom via recovery.
Personally, I'd go with number 2 because a) you wanted to update anyway and b) if you have the right recovery and rom, it'll be easier as you can just put the files you need on an external SD card and install via the custom recovery. Now, not all recoveries are able to flash any file. Many times you need specific ones to install the newer android versions. So, if you are wanting to install something 4.4 based, then using a recovery that was made, say, last year, probably will not work well if at all.
Another thing to try first, is to wipe the cache and dalvik cache in recovery since you said you tried to install a kernel. It is always recommended to wipe these when installing (assuming you did pick a compatible kernel with what you were trying to install).
