Upgrade GS2 I9100G To CM10 - Galaxy S II Q&A, Help & Troubleshooting

Hey guys, I'm looking to flash CM10 on my friend's Galaxy SII I9100G previously running GB (2.3.4)
I've read the tutorials, I need an ICS bootloader to flash CM10 over it.
My question is: Is there an ICS kernel with CWM that I can flash on the device then install CM10 or do I have to download the official ICS ROM which is 340 MB, flash it with Odin then flash CM10 via CWM?
All I'm looking for is a way around this 340 mb download
Thanks!
(I'll be glad if someone posts a helpful tutorial)

There are very clear and concise instructions in the very first post of the official CM 10.1 thread in the i9100G development section.
EDIT: I think I see your question. Kernel is NOT the same thing as bootloader, nor does a kernel contain the bootloader.

All I want to know if there's a way to avoid downloading the official ICS ROM and flashing it, can I flash the 'ICS bootloader only' ? and where can I find it

Yes, you can flash the bootloader only.
As for where you can find it - I don't suppose you tried googling it? I found it in 0.5 seconds this way.
EDIT to add: as an aside, it's been 12 hours since your initial post. You could have downloaded and installed the full stock ICS 10 times over by now

[Q] Please Need Advise Before I Install CM9

Hi I want to install latest CM9 nightly, As Im installing first time, I just want to make sure that my phone is running firmware lower than XXLPH though it looks lower but cant judge, I went through official CM9 Thread I can follow all the steps except this one. And also I have already rooted my device using
GT-I9100_THR_I9100JPKJ2_I9100OJPKJ1_I9100XXKI4 (firmware) and
CF-Root-SGS2_XW_XEF_KJ2-v4.4-CWM4.tar (root kernel)
I still havent installed any custom rom yet.
Here is my current phone details:
GT-19100
Android 2.3.5 (STOCK)
Baseband 19100XXKI4
Kernel 2.6.35.7-I9100XWKJ2-CL676699root
____________________________________________
I thought my firmware is higher than XXLPH so I found this guide to ugrade to ice cream firmware first:
http://androidbeast.com/937/tutoria...oid-ice-cream-firmware-on-galaxy-s2-gt-i9100/
then root it with this kernel :
http://androidbeast.com/948/root-samsung-galaxy-s2-cf-root-kernel-odin/
Now I need your advice that weather should I continue following above guide or should I start flashing CM9 firmware staright away ??
now that you are rooted and on ics, you can then follow the instructions in CM9 thread.
Flash odin version first and then update to latest build from cwm recovery
codeworkx said:
If you're a bloody noob and getting confused by following simple instructions, go down and read about using the noob-proof ODIN method.
First time installing CyanogenMod 9 to your Galaxy S II, or coming from another ROM:
- READ FAQs: http://teamhacksung.org/wiki/index.php/Experimental:GT-I9100:Frequently_Asked_Questions
- Make sure you're running ICS bootloaders lower than LPH: Download (flash as PDA with odin or extract and $ sudo heimdall flash --primary-boot boot.bin --secondary-boot Sbl.bin)
- make sure you're running a proper working CWM like the one from CM7
- Copy GApps and CM9 ZIPs to your internal SDCard
- Boot into Recovery
- Flash CM9 zip
- Flash GApps zip
- DO A DATA WIPE / FACTORY RESET (otherwise your calendar sync will not work)
- Reboot
- Don't restore Apps using Titanium Backup!
Upgrading from earlier version of CyanogenMod 9:
- Copy CM9 ZIP to your internal SDCard
- Boot into Recovery
- Flash CM9 zip
- Wipe cache partition and dalvik-cache
- Reboot
Using the noob-proof ODIN method:
- Download CM9 Resurrection Edition
- Download GApps and put it onto your internal sdcard
- Open Odin
- Choose cm-9-XXXXXXXX-ODIN-galaxys2.tar.md5 as PDA
- Boot your phone into download mode
- Connect your device via usb to your computer
- Wait till Odin has fully recognized your phone
- Hit the start button and wait till the flash process is finished
- Device boots automatically into recovery
- Flash GApps, wipe cache and dalvik-cache
- Reboot into CM9
- Follow above steps to update CM9 to lastest available version (Upgrading from earlier version of CyanogenMod 9)

Yes, follow the "noob proof" method. (which doesn't seem too noob proof at the moment... :/)
And seriously, why did you start two threads (this current one, and this other one) about flashing an ICS ROM? CM9 is considered an ICS ROM, so really the topic is the same.
Hi.... i recommend this site galaxys2root.com
it helped me figure out a lot of stuff in the beginning. Video walkthrough of installing roms is really a big help.
For the latest Ressurection Remix 1.2 looki the Android developer forum.
I am about to install now
Hope you get it all sorted

Actually on that post I wasn't sure which ROM was based on what firmware but i came to know from users like you and I got clear idea from you all before that in the mean time, i was gathering info through various guides, videos from weeks and merged those ideas in to one then I decided to install CM9 as it looks similar to new galaxy nexus phone and this is exactly what I wanted my phone to look and behave like. Now I am happy and satisfied.
I have done oden with bootloader but in the middle of that the bootloader progress in oden is turn to red and cell get off. now its hard bricked, dead, what i can do

Man... why did you the touch the bootloader first? never play with it unless you know whats gonna happen! and about noob installation guide for CM9 is not clearly noobproof, I completely did all installation with clockworkmod recovery, I used ODIN only once for rooting my phone after that i never used it as I was very very cautious and careful about each and everything bit i was doing.
But never loose hope, you never know what kind of brick you have you have two ways to unbrick your phone,
1.Using USB jig, search it on XDA, Google, Youtube
2.JTAG Service, This is the ultimate solution if your phone is completely Hard bricked but for this you have to send your device to them.
here is their demonstration:
http://www.youtube.com/watch?v=kQdTi2vgMmY
its written in the cm9 installation to do the boot-loader with ODIN, that is what i do
oh bhai....... make sure you had i9100 not the i9100G,
remove battery and see if you can get download mode.
im running cm9 on new bootloader unless intratech still removes them from his stock ROm as he used too..... i came from stock LPS to cm9
that much sense i have dear its s2, and ya its dead, i send the cell to lahore, khi, rwp, but no one have jtag proper equipment

you dont get it i9100G is also S2 and virtually same. you have to see under the batter if its written i9100 or i9100G.
because thats what would happened if you flash i9100 bootloader onto i9100G.
plus faulty usb, dead battery can do the trick aswell.

rom compatibility question

Good day guys
1.Does cm10 compatible with siyah kernel?
2.is cm10 now official or beta?
3.can i just use the backup from cwm if i want to restore things after i flash cm10?
4.cm9 or cm10? (Better)
5.if i flash custom rom does it unroot my phone and remove cwm options?

1. Not sure if its been updated... you could ask or check in the respective thread.
2. Official Nightlies just dropped for select devices.. check dev section.
3. Yes
4 Neither.. CM9 based on ICS, CM10 based on JB.. Both are awesome and JB is the newest shiz so... (and actually CM9 may have more features right now)
5. 99% of the time no. Unless you flash a ROM w/ Odin that does not have root or CWM. But- most, if not all, the custom ROMs you find here will have root and CWM. Just look at the ROM features before flashing!

Answer for 1. is YES it's compatible with CM10. Just look at the thread title of siyah kernel.
The rest bit is already answered by Coreym

1. Yes siyah supports cm10. Says so in the title. Always read the change logs for important info
2. It's in beta sort of. They're releasing previews that are quite usable. I'm using it atm. Only annoying bug is the memory leak that can easily be solved by rebooting the phone. 3. Restore only app apks, not phone settings. Restore app data at your own risk.
4. Depends on if you're looking for stability. CM9 is stable but I like JB and I'm going to be sticking with CM10
5. No it doesn't. Flashing a stock rom with stock kernel will unroot it. Custom roms will not

Go to the Original Development section and get CM9 from there. Its good for you to navigate around the site and get comfortable where stuff is. In regards to the bootani, in my experience you change this by modifying /system/media/bootanimation.zip. You can try swapping the new bootanimation.zip with the old bootani.zip and see if that works. But I've never flashed a .zip to change the bootani.. but to be fair its been a long time since I've had any desire to change the bootanimation

Lol.. sorry. Like I said you need to get comfortable with this site and not just ask for links.. if you can't find em sure, but you need to try. You can do it two ways- on your PC: at the XDA home page you'll see 2 search boxes near the top and to the right. The box that says "find your device" ..type your phone in there and choose it when the option comes up. Then scroll down.. bam- OG Dev Forum! Or download the XDA app and find your device that way-
I hope you find it but I'm confident you will

JB Bootloader and other??'s

Hey all. Quick question for ya. I am going to flash one of the JB roms to my wifes galaxy tab 10.1 this weekend.
She is currently running task's honeycomb rom. She has been running that for a good 5 months now.
What order do I proceed to get her to JB??
Must I flash an ICS rom first then flash a JB rom??
Do I need to flash a JB bootloader or an ICS bootloader?? If so where can I find them. Been searching the forum with no luck.
Any other info would be greatly appreciated. Specifically the orders or anything I have overlooked.
Thanks in advance,
Nycorduroy
not mandatory to have an ICS step, you can directly go to JB.
you just need CWM, you probably already have it if you are running task's rom.
backup your app (titanium is a great tool in my opinion)
copy rom file to your tab
make a full wipe (+cache +davilk)
flash rom
reboot and enjoy

This does not belong in the Development section. All questions need to be put into the Q&A section. Please do that from now on.
With that said, I am not sure about the bootloader but you probably need to update your version of CWM recovery, and you can find out about that as well as the bootloader stuff in the threads for CM10/JB. Pershoot's threads are probably a good place to look as well.
Edit: well someone got to it first, follow their instructions as well

Yes, Pershoot stated in Android 4.1.1 - CyanogenMod 10 Preview thread that you need to have a US HC or ICS bootloader in order not to have charging SODs. If you have a US bootloader you should be fine if not flash a stock US HC or ICS rom via Odin before you flash CM10 (you'll loose all data on the tab). Alternatively there are flashable US bootloaders but I've never tried one. I can't put the links because search feature is is temporarily unavailable.
Finally, You could still get charging sods and some wifi problems etc. even if you came from a US bootloader. Pershoot says a small minority will face these issues no matter what. A hard reset fixes these issues temporarily. If you could wait a little bit more a new cm10 is on the way with 3.1 kernel which is supposed to work fully functional. But still, I think current CM10 is the best rom available right now.

Yeah everything ok but why to flash CWM recovery?
How do I check I have proper working CWM as mentioned?
Because you need cwm to install a zip file to your phone.
If you have siyah running on your device, you have cwm recovery. Use that.

No. Like the link says, its a rom for the i9100G. Yours is the international version. You need to use a ROM that's built for your variant else you brick your phone. Use the search button and read ROM descriptions and instructions before installing.

Are you saying the cm10 thread doesnt have links or install instructions.
If you are lazy and cant follow simple instructions,then modding your phone isnt for you.
Havent you learned ANYTHING since the last time.

You are right, go for SiyahKernel (latest) (safe -> no mmc) Flash it with Odin.
That will give you a safe kernel with Root then you can follow instruction in CM website (CM10 zip + gapps) to get a working CM10.
Search XDA for more help. There are lots of articles on this!
Same prob here..
