Hey folks,
I just bought the white international SGS II and i'm loving it!
I previously had an Infuse 4g, so I am pretty experienced with flashing/backing up/ restoring...but I have questions/concerns regarding the I9100.
I am about to try out the CM9 Unstable, so I backed my current stock ROM up using CWM Manager 3.0 (I am on CF-Root 5.0) onto my Internal SD, as I do not have an external SD card.
Now, I have had bad experiences with CM7 with Infuse and ended up not being able to restore due to many problems like MD5 mismatch, different CWM version, and problems while restoring ( I think it said something like devblock??)
So I'm pretty worried about not being able to restore back to the backup i just made.
So correct me if I'm wrong folks,
1) Go into CWM, flash CM9(once? twice?), Gapps, Faceunlock,
2) Data wipe/factory reset
3) Reboot
and should I choose to restore back to the stock Rom backup,
just go into CM9's recovery and restore..?
will this method give me problems restoring? will I have different versions of CWM recovery from the one I have currently? Is there any way to check if my back up was made properly?
Thanks a lot folks! Appreciate it!
Edit: "Make sure you're already running ICS bootloader (if not, go to SamMobiles and flash XXKP2 bootloader)". Is this necessary? Cus I have seen some folks say that they've not and was fine installing CM9.
First the procedure:
1. Wipe
2. Install CyanogenMod 9
3. Reboot
4. Install CyanogenMod again
5. Install gapps and face-unlock
Worked for me every time.
Your backups should work unless there were errors while creating them.
If you want some more safety, you can create a new backup after flashing the Siyah-kernel. The latest version uses the same version of ClockWorkMod as CyanogenMod 9.
Whether you need to flash the bootloader or not, depends on whether you already have it or not. I'm running galnet-MIUI and already had the bootloader installed. I don't know how to tell if you have it.

Ok...
I did further research and found out that Nandroid backup backs up everything EXCEPT the kernel.
I'm pretty sure that CM has its own kernel...but will it be CWM 5.0.2.7(the one i made backup in.)?
If it's not, the correct steps for me to restore my nandroid back up is to
1)boot into download mode from CM9,
2) put the cf-root kernel that i used in the ODIN PDA, flash,
3) turn off phone, reboot into CWM, then restore my nandroid back up right??
Can anyone please confirm this method??
I only have this phone and I cannot risk soft-bricking or hard-bricking this beautiful device.
Thanks in advance!
Also, i made a back up in blue recovery of CWM 5.0.2.7..does that matter?

thanks for the reply,
so I must have the ICS bootloaders in order for CM9 to work?
ooo siyah kernel method... that makes it easier! haha thanks so much!
I will proceed to do that!
btw, how is CM9 working for you?
do you think you'll be able to use it as a daily driver now that NITZ is gone??
1. Afaik cwm backs the kernel up and restores it too. (afaik = 99.9% sure, in this case)
2. CyanogenMod ships with its own kernel.
3. The kernel is not cwm. ClockWorkMod is just the recovery that is integrated into the kernel. CyanogenMod 9 has cwm-recovery 5.5 (Siyah too btw)
4. You don't need to use download-mode to restore.

You must have ICS-bootleggers. He did not say that for fun xD.
Is it suitable as daily driver for me?
Nope.avi
Why?
Accelerometer is unresponsive, so it takes forever to flip your screen.
Battery drainage is horrible.
Camera isn't working properly.
And the biggest no-go for me:
The device gets way to hot when using it.

alright,
thanks for the information!
I'll flash the Siyah kernel
Btw,
Flashing CM9 Zip does not flash the ICS bootloader right?
so then if I want to restore to my GB 2.3.5, would I need to flash GB bootloaders before restoring via Odin??
If the zip would flash the loaders, he wouldn't have mentioned it.
They're backwards-compatible.

If you need to make a post in the Q&A forums about flashing CM9, then you are definitely not the sort of person who should be flashing it. It is in very much a beta stage and there is a very high possibility it will **** your phone up even if you have done nothing wrong. If that happens you need to be the sort of person with enough experience to solve the problem by themselves. If you are asking questions before you've even flashed it then really, it's not for you. Use CM7, at the moment it's better than CM9 in every single way.

It's not thaaaaaaaaat bad. I mean, he won't be able to brick the device through cwm.
If he doesn't ask, he will never learn and it's always better to ask twice than to break something.

Thank you sniper =) really appreciate the support.
Ive been flashing and restoring before with my infuse 4g. Just sometimes ran into problems with restoring with diff CWM versions and stuff. This phone is very precious(expensive) so i thought i would learn it for sure before i attempted anything.. thanks anyways for sharing your opinion!

I couldnt agree more... i think people here on XDA need to stop trying to be all hot **** saying Oh you asked a question your a noob... in reality most ppl here want to ask the same question but dont because afraid of getting *****ed out... and when someone else asks... try to be badass and put the person down...
Iv used a Galaxy S and a Moto Atrix and now a S2... flashed the life out of each phone along with all kinds of stuff and mods... yet i would have wanted to ask these same questions before flashing hence googled and found this thread... So thanks to those that replied as well... i was about to flash ics till i read this and guess imma hold back now even more...
But again i think people here need to calm the hell down... a person asks a question in the thread and you call them a 'noob' and what not... a person asks a question in the Q&A section and again you tell them off... stop being such anal retentive trolls...

Most people should not flame some one as long as they show they have at least tried to look for an answer first. Yes we were all new at one time but we all learned.
Like you said you Googled and found your answer. Not that hard.
Think it's bad now. Should have seen it a few years ago. Lol clutter up the threads with questions that the answers were found with a search. You got warned. Do it twice and you went on vacation for a few days to learn how to search. So the next time you think people are being too hard. Remember it is not as hlbad as it was.
When I search for the answer, I ended up here.
are these considered ICS bootloaders? If not, when would you flash them, because they are completely unmentioned in any of the instructions or FAQs

I'm trying to put a better ROM on my wife's GT-I9100M I really just want something which much better battery life and speed for her... mostly battery life though.
With so many different kernels out there, I'm a little wary of installing something now, in case it'll brick the phone. Does it matter what kernel these roms are based on?
Her baseband is I9100MUGKG2
and her kernel is 2.6.35.7-I9100ZSKG2-CL361136 [email protected] #6
and build number is
GINGERBREAD.UGKG2
I'm sorry if I'm posting a redundant thread, but I've spent a few hours on here, and Have still no idea what get.

so i imagine ur wifes phone is stock right?
then ur going to need to root the phone first :L
Then i wuld recommend speedmod kernel or siyahs kernel for the best battery life.
Im running Checksrom with speedmod kernel, and usually get a decent 2 days out of it

It's rooted, so that's done... I don't have to worry about bootloader or anything?
I'll grab what you have and see how she likes it, since it sounds like it's working for you.

PS. I got the Speedmod kernel, but where do you get Checksrom?
Same here: CheckROM v4 and latest version of Speedmod kernel and the battery life is around 2 days. Smooth, no FC's, no issues!

No no worries about the bootloader
just install Checks rom, and it comes with a kitchenapp and u can change the kernel to speedmod from within that.
BUT
make sure that the i9100M is compatible with the rom!
PS
if ive helped dont hesitate in saying thanks
Edit: my bad, just googled I9100M and found out its indenticle to the 19100 except in the name xD
so u shuld be all gd to flash, but make sure u backup before just in case.

Ok this is weird... I installed it using CWM and rebooted... it looks exactly the same as before except under about phone it says Build # is CheckRom RevoHD v4... And where do I find this kitchenapp? I don't see it in the app tray. Gonna do a reinstall of the ROM, I'm not sure if it really... took.

Well. So far so good. She hasn't really noticed anything different. In spite of my backing things up with titanium she's still swearing at it and setting some of her stuff back up.
We'll see how it goes now for battery life. That'll be what she wants most. The regular stock had the phone dying within less than 10 hrs or standby.

How do you find the right rom ? You try out a bunch of roms until you find one that works well for you. If you think you're going to have the same experience as someone else with a given rom or kernel you're mistaken.

Hey ! I have a soft brick Prob can you help me out.
Heres the Prob: Phone recovered from soft brick through Odin (FIRMWARE=KI3). Flashed ChainFire's kernel for KI3. Added CheckRom v4 and my own rom to the external SD card. Got into recovery, Wiped everything including BatteryStats booted Check ROM. It boots up but as soon as it's up error msgs come (Force Close ones).
Need help in fixing! PM if you are willing to tell me ! Plz Reply!
Why are you hijacking this thread ???

Not sure how you got 2 days battery on that ROM. My wife is only getting 12 hrs. . Might have to try something else.

+1 Pretty much nailed it. Won't know how good a rom is until you try it out yourself.
The problem is, not every rom for samsung GT 9100 seem to be the right ones... What I'm saying is, I can't just grab any ROM from this site and slap it in, it seems like they have to have the right kernel or combination of stuff to work. I don't want to soft brick it, so it would be nice to know exactly what would be safe for my phone.
There doesn't seem to be any rhyme or reason to these roms.
Hi there
-I'm on AT&T using a SGH-i777
Right now, the Android version is 2.3.4
Kernel Version is 2.6.35.7
Not sure if all of that stuff is relevant, but hopefully it helps.
I'm very new to flashing, rooting, and all that good stuff in general, but today I attempted to follow a guide in attempt to put CWM on my phone, and then I would use CWM to flash Cyanogenmod 9 on it next. Being the complete noob that I am, I only realized too late that the Kernel provided in the guide was for the GT-i9100, and not the SGH-i777. Right now, the phone will boot up into Android, but displays the GT-i9100 and a yellow warning sign at the boot loader before launching into android. So far, I've not noticed any adverse side effects due to mis-flash, other than it being, you know, the wrong kernel. I've rebooted into CWM, and so far I believe that works, but I'm honestly not sure where to go from here.
The guide I followed was: *Can't post links as this is my first post, but it was on the cyanogenmod wiki, titled as, "Samsung Galaxy S II (AT&T): Full Update Guide"*
The kernel I installed was named: "codeworkx's Kernel with the ClockworkMod Recovery 5.0.2.3"
So essentially what I'm wondering here, is where should I go from here? I was thinking I could flash a new kernel on my phone, but I think I only got lucky here and didn't brick it, so I'm hesitant to follow random guides I get from Googling without someone with experience thumbs-upping it for me. I'd still like to put Cyanogen on my phone, as the official ROM(Right terminology?) that was pushed from AT&T sucks and lags while opening messaging and the like, and unless anyone would be willing to recommend another, better ROM, then I'll probably go with it once I get this worked out.
Thanks in advanced

yes your lucky u didnt brick as far as i know that would usually do the trick....the only thing i can think of is starting from scratch. go into the development forums for our phone and there is a simple process to restore to stock and start over but someone here might know a little more but thats what i would do honestly
What makes you think it was a GT-I9100 kernel? From the name, I'm pretty sure what you flashed is the codeworkx CWM kernel for the I777. The boot screen that says GT-I9100 and has the yellow warning triangle would appear any time you flash a custom kernel using Odin or Heimdall. If you had installed a kernel which is actually for the I9100, you would not be able to use all of your capacitive buttons. You should be able to flash the firmware of your choice using recovery from your current setup.
Oh man, do I feel dumb or what?
Thanks for the quick help, I really wasn't lying when I said I was a noob at this!

anyway since u already got CWM then u can start flashing ROMs & afaik CM9 is still in nightlies or not as stable yet for our device. u can try other ICS ROMs which are more stable, like SHOstock or Semi, its your choice.

This is a thread for USEFUL discussion about the logistics involved in reverting the Razr back to GB (please keep the discussion on topic). I know there are those out there that want it.
I am throwing 50 bucks into a pot to the Dev that first finds a way.
What I have gathered. With the release of kexec, we now have the ability to flash custom kernels to our Razrs. From what I understand, the thing preventing the reversion to GB is the change from the GB kernel to ICS kernel...
So in theory, we should be able to fllash the gingerbread kernel, then the stock GB rom and we should be good?
Thinkin out loud, is any of this sound feasible?
EDIT: Bounty withdrawn, seems impossible due to locked bootloader as well...

Hi!
This is a feature request. There's no development involved. You should post questions in QA section. Or make the same question in kexec thread.
Thank you!
sorry for the wrong spot.. i didnt want to hijack the kexec thread and move it off topic. I thought there would be development involved in getting a GB kernel ported to work with kexec.
maybe someone else with more knowledge can chime in. My bad if i am mistaken
Sorry, but for what i understand,
Kexec able us to load a custom kernel after boot and not flash a custom kernel.
so i think dev have to find an other way. But they have more stuff to do than finding a way to downgrad i guess

I agree. Many devs are focusing on stabilizing CM9 and working to bring us CM10, I dont think GB is on their agenda but maybe some dev is willing to do it.

Is anyone able to confirm this is actually how Kexec works? and along these lines, i mean why couldnt we just load the GB kernel like any other custom kernel?

Yes i realize most are, thats why i was putting my money where my mouth was. ICS has been a disaster for me on 3 razrs i am currently back on my bionic. I was hoping it would be a fairly simple project since all i was thinking needed to be done was to update the existing moto GB kernel for Kexec, and make a flashable zip of the stock moto GB rom
but i :dunno: im not a dev by any means

Yes, it will verify the signature of your stock kernel then at just the right time hijak the boot process and load the custom kernel. I'm not a dev so i can't say if it can be done or not, but i would imagine not.
Edit: meant to add i think the biggest problem is that the bootloader changed between gb and ics. So without am unlocked bootloader don't think its happening.

So basically, without being able to also revert my bootloader version, i am up the creek as they say.
Thanks for the info, definately an educational experience...
I ended up buying a new Razr Maxx off ebay that still has GB, now i just need to root and freeze the updater and im golden
Alright, I'm a noob...(loved the intro video!) and I've spent an hour or so searching for rooting info for my device. Did find a good thread that was over a year old about rooting SGH-i777 with older android versions, but was afraid to follow THOSE directions since mine has newer version (Android 4.0.4). And I find other threads about rooting other versions of GS2...not the AT&T.
So far I've learned NOT to use ROM Manager, and not to look to Galaxy2Root for help...so I guess there's that. I don't want to be stupid here, but can someone direct me to a thread with Rooting instructions for my phone with ICS already on it, and recommended ROMs. I'd like to have more control over my phone and take advantage of JB releases that seem to be out with good reliability. I'm used to doing this sort of thing on computers, but not with Android. Had my phone for about 15 mos....my first Android.
Suggestions?
TIA...

This is so far easiest thing to do, however be careful, DO NOT, DO NOT,
choose the "one click" patch option which come first, as that will patch
the system and you will NOT be able to root again. and there is NO way
to un-patch. I was not being careful and now trapped.

Appreciate the suggesting. Been researching ExynosAbuse, and looks like it could cause camera not to work, and in the compatibility list, though the Galaxy Sii 9100 is listed, the SGH-i777 is not...seems like a concern to me.

It works trust me. Also you're going to flash a rom right after so you should be fine

I am also a noob when it comes to anything mobile. I got my GS2 last year (first android as well), and I've since updated to 4.0.4. I have also done some research on rooting(after my fiance keeps bugging me about "fixing" our gs2s due to them always turning off) but I was uncertain on what rom to use. I have no experience with phones, and I don't want to do something stupid and break our phones. I know that I am supposed to " use exynos abuse", but that's pretty much all I know/can find without reading every page on the 80 page threads. Are there any suggestions on a stable(ish) rom for us both to use/how easy is it to "use exynos abuse"? (without doing what tyhust did) We are fine with our ICS and I wont venture into the world of Jellybean yet... (maybe once I acquire some more experience)
Thanks in advance, and for the site in general, there is a TON of information on here...

If you want you can downgrade to 4.0.3

I'm also a noob... so if I want to down grade to 4.0.3 rooted from 4.0.4 stock, should I use ucle5_stock_rooted.tar with Odin?
Is is necessary to wipe since both are ICS?
Thanks!

Yes, that should be the tar you use. Make sure it's from this thread. You should be okay without wiping, but if you have problems, I'd suggest flashing 2.3.4 and wiping from recovery once on 2.3.4; reason being, stock ICS kernel may brick your phone if you wipe with it (see linked thread for details on this eMMC superbrick bug).
OP, if you're uncertain about ExynosAbuse, try this method instead. I know it works, I used it myself very recently, albeit I was already on 4.0.3 and had not upgraded.

This is a good thread.
I had the same issues with 4.0.4 and i found it was a live wallpaper app (water drops) causing my random "power off". Since switching to a different live wall paper, i have had NO random "shut downs".
I still want to root my S2 and this is the best thread i have found that addresses the stock 4.0.4
good luck.
Well, after a week of no shut downs, my phone just shut off. So i guess the live wallpaper was not the issue.
Back to the drawing board
Not to hijack the thread or anything but I'm new to this phone too. I understand the rooting process on ICS what I don't understand is installing a custom recovery and kernel. Why do you have to use a gingerbread kernel and why can you not just use stock? I've always just rooted, installed custom recovery and flashed roms on Verizon phones so installing a custom kernel to achieve custom recovery is foreign to me. I've been reading the stickies but I don't understand this....is it only to avoid the flash counter being tripped? Is there a easier way to install the recovery or am I making this harder than it needs to be? Thanks for any help!

Our phone has recovery baked into the kernel. For what reason I don't know but I'm sure its a good one as just flashing recovery is IMO easier.
Thanks. Last question. After installing a gingerbread kernel and the baked in recovery do I need to install a new kernel to flash a jb or ics rom. Sorry for the noob questions. Thanks for your help.

Well since every ROM comes with a kernel in it (obviously or it couldn't run) then you just answered your own question bro. Flash away.

Need more help.... There's so much information since this phone came out its overwhelming and it seems most of it was written for gingerbread. I have the phone rooted, mobile Odin lite installed and I'm confused on which kernel I need to flash. Phone is stock rooted lk3 4.0.4. Thank you!

If you're just trying to get into recovery to flash something then any kernel will do. Since the system won't need to boot up with that kernel installed you're just flashing one to enter recovery.

So I want to install a gb kernel and recovery only so I can flash a custom rom that comes with kernel and recovery, correct? So before flashing the gb kernel in mobile Odin I should have a rom already downloaded on the sd card so I can immediately flash that? I'm sorry for all the questions this is drastically different from what I'm used to.

Download whatever ROM you want on your phone . Flash a kernel. Reboot into recovery. Profit.
