Hi guys, thanks to the great tuturuals i've succesfully rooted my device But i have a question. Im still new to the hole android and rooting, so please bear with me.
After i flashed my XWKE7 kernel with the CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4 kernel, i followed the tururial to get rid of the yellow triangle. I flashed origial kernel back on my device (I9100XWKE7_Nernel), however my device is still rooted... So why should i follow the rest of the tuturial to flash the cf_kernel with CWM?
Isnt it better/more stable to keep running it with the original kernel? The root is still active, so why should i flash the rooted one back with CWM?
bump
really nobody?
The (for me important) difference are these:
1. While the phone is not booted yet, you can still access superuser through adb. This is important if you screw something up and the device is in a boot loop.
2. You have ClockworkModRecovery, where you can take backups, install updates from sdcard etc.
I don't think the original kernel is more stable, because the custom kernel is based on the original.

I bought sgs2 few weeks ago, had some fun with stock and samsung apps, then I decided that some changes would be nice
found this great forum, with all knowledge and I have to admit I'm overwhelmed and kinda lost.
rooted my phone with Doomlord method (zerg rush exploit), worked like a charm, installed Titanium Backup, that went smoothly too. From what I understand that didn't change flash counter so I can unroot and keep my warranty in case of hardware problems, am I right?
Then I installed ROM manager and here is where problems started, when I click Flash Recovery it's downloading some file, but when I boot to recovery mode, there is info about e: failed to verify whole-file signature and I can only reboot. If that failed, what did it exactly do with my stock firmware and flash counter? please forgive my noob questions, it's my first android device, I'm reading and learning, but it's a lot to process.
I have branded Play (polish provider) firmware (2.3.3, XWKE7) and I can't upgrade it, cuz I can't backup stock firmware with CWM, I'm afraid to flash without backup in case I need take my phone to samsung.
I would love to at least upgrade to 2.3.5 or try some nice custom roms you guy cook here so skillfully but need some advice any info will be greatly appreciated
Hey hey,
This happens to me too when I installed ROM Manager, and then Flashed a recovery. It does not boot into the orange ClockworkMod Recovery, instead it boots into the stock recovery saying an error.
Don't worry, it did not do anything bad to your phone, it just attempted to install the ClockworkMod recovery but just fails, no biggie All you have to do is flash a custom kernel through Odin, such as CF-Root or Ninphetamine, then you will have ClockworkMod Recovery installed by default. The flash recovery option is for other phones that do not have the secure kernel that Samsung installs into your phone by default.
I use CriskeloROM on my phone, in my opinion, this is my favorite ROM because of the constant updates and massive collection of add ons. It is currently running on 2.3.5 and has a base of XWKJ2. Check out the link in my signature for more details about the ROM.
thank you so much for your answer, good to know I didn't break anything (yet! )
as you advice I will take a look at Criskelo ROM
I am currently learning and experimenting with rooting, custom roms etc.
Wondered if someone that knows more than me can help me with a few questions I have?
I have rooted my GS2 using CF Root XWKI8 kernel on Odin. I have full root access now and I have made a backup of my factory ROM which is Three firmware.
The questions I have are:
1) How do I remove root access if I need to? Would that be by putting the original kernel back on?
2) Some people have said you can remove the yellow warning triangle by re-loading the original kernel but would that remove the root access if this is how you unroot a CF rooted phone?
3) I am thinking about loading CM7 on the phone using clockword mod. When you load up a new firmware does it have its own kernel that is then put on the phone?
4) If after loading up CM7 onto the phone I then decide to restore the original Three firmware using clockwork mod, what kernel would go back onto the phone? Would it be the CF rooted kernel as that would have been the current kernel when I performed the backup?
Its important to me that I understand everything completely before I play about anymore!
Many Thanks
Dave
1) You can flash a Stock Kernel with Odin to remove root.
2) To remove the yellow warning you first flash a rooted kernel (such as CF-Root), then you flash a Stock Kernel and when it reboots, you use CWM Manager to flash the image kernel from there. That way you keep root and CWM, but the yellow warning doesn't appear any more.
3) Many ROMs have their custom kernel in the same package, so it will overwrite your current kernel. All custom ROMs have a rooted kernel, so despite changing the kernel, you will still have root and CWM.
4) If you did a nandroid backup, you could restore the kernel from which the nandroid was done. If you don't have a nandroid backup, you can flash a Stock ROM to leave the phone as you bought it.
Many thanks for your help.
As I first of all rooted my phone using a CF Root kernel and then did a nandroid backup in clockwork mod of the Three firmware. Would the backup now include the CF Root kernel when I restore from CM7 back to Three firmware or would the original kernel still reside within my Three backup and be restored instead?
If you have the European Galaxy S II (I9100) can you use the CM7 stable build thats on the official CM website or do we need to find one within the dev section here? Anyone know please?
@DJGREEN1980: Since you've done your nandroid backup with CF-Root, when you restore it you will have CF-Root again. If you want to revert CM7 to Stock you can directly flash a Stock ROM, instead of restoring your nandroid backup.
@mikeDCMDVA: There are only 2 versions of CM7 for SGS2. One is for AT&T mobiles and the other is for the rest, so you should be able to flash this last one on your phone. If you have further questions about CM7 I would suggest you post them on CM7 post on XDA or CM7 forum, since CM7 users would surelly have more knowledge than me about that.
Do you know where I would get the stock rom from? My phone is locked and branded with Three firmware.
Thanks for your help
There's a post with all stock ROMs up to date here: http://forum.xda-developers.com/showthread.php?t=1075278
Brilliant. Thanks. So restoring to the latest Three rom XWKI8 would bring the warranty back for the phone after using a custom rom?

Its not that it will bring the warranty back, its more that you could send it to Samsung Support without them noticing you've used a custom ROM. I recently send my HTC Desire to HTC support reverting it to a Stock ROM without problems.

unless u reset the binary counter how will this work ??? of course buy a jig from ebay which im sure he forgot to mention
Hello I am from Argentina, desperately need help.
I rooted my SGSII ICS 4.0.3 phone with CF Root LPJ everything went as expected. Odines PASS! and all but when my phone reboots it just turns off after logo screen with triangle.
I can get into recovery and download mode but that is all.
What should I do?
Might commit suicide if there is no fix.
Flash stock rom.
You can find it at sammobile.com.

If you can get into recovery and download mode, you are only softbricked. It could be worse.
Please be more precise, I lack experience but I will understand.
Which stock ROM should I flash now?
Because I got a downloaded I9100UHLPS_I9100AROLP4_ARO but it is not LPJ.
I also managed to find Kernel_I9100XXLPJ at intratech. Would flashing this kernel fix it? Could it possibly mess my recovery mode and brick my phone?
Flash the same ROM again using Odin, do not flash the wrong kernel.
ARO is a good ROM, just flash it again, it will boot, then root with the cfroot for that ROM later.
What do you mean by the SAME rom? I got this problem flashing a CF-Root kernel not an entire ROM.
The ROM I had before was ICS 4.0.3 which I upgraded officially via Kies.
Should I flash ICS 4.0.3 UHLPS that is for my region? I9100UHLPS_I9100AROLP4_ARO
I'm pretty sure that's what Atifsh meant, yes.
Thank you all! Thanks given with the button for all!!!
I flashed stock ICS 4.0.3 for my country downloaded from sammobile.com and the phone recovered with no trouble! I got my soft bricked SGSII working again!
Is there anything I need to wipe now to make sure there is no crazy leftover from the CF-Root boot fail?
If it's working fine, then probably not. I mean, you could always backup your contacts, call logs, SMS, etc and your apps with Titanium, do a factory reset, and then restore contacts, call logs, sms and user apps/data only (do not restore system apps or data).
But if it's working fine now, I don't see the point.
I want you to do two things for me tho.
First, get kTool either from Google Play (it's free) or from Hellcat's thread on here. Then backup your EFS. Keep one copy on your external SD card in your phone, and keep another copy on your PC. Then I want you to do a Nandroid backup in CWRecovery.
That way if anything does ever go wrong, you should be able to recover/get up and running again easily without losing your stuff. For example, if your phone ever borked & you had to send it in for warranty service/replacement, you could restore that backup when you get your phone back/a new phone.
Do a backup at least once a week and certainly every single time before you flash a new kernel/rom or if you make major changes to your system.
I am afraid of doing anything with this phone now. First experience = soft brick.
Damn I almost die. Now I need to find a way to get out of this stock 4.0.3 ICS because it is ramming through my battery and is as slow as a potatoe.
4.0.4 is eMMC hard-brick possibly if I wipe after flashing.
Now I feel like an expert.
I also tried flashing cf root today and it softbricked my phone. Weird.... next time I try to root my phone, I wont be using cf root.
Which Kernel was yours? Leave it here logged for future brickers.
Mine was LPJ
Hi, this is my first post. I'm a total noob in customizing phones and since my phone is quite old, all the information I can find is years old, talking about file versions that don't exist anymore, or became outdated since there are so many different versions of android.
I have been trying to find a good guide to help me do the correct steps to follow to flash Cyanogenmod. I might try the latest 12.1, and then see if I like it.
This is what I have so far:
- international i9100, I live in panama if that's relevant to any help I need
- stock ICS 4.0.3 (with XWLP7 kernel)
- used superoneclick to root, it installed CMW PhilZ touch 6.0.1.7 (I think, can't remember the last digit.)
- used "galaxy s unlock" app to unlock the phone
I downloaded this: philz_touch_6.07.1-i9100 from d-h.st/hUX, sorry I can't post the links correctly for being a new user.
I just made a backup before i will attempt to load philz touch 6.07.1. I read that I need to have a kitkat compatible recovery, is this one compatible. Can I simply flash it or do I need to do anything specific before.
I am trying to follow the steps explained in wiki.cyanogenmod.org/w/Install_CM_for_i9100, but the warnings scare me a bit, can someone please explain the workarounds, thanks.
So, what I'd like to know is the specific steps for my version of android to make it migrate to CM12.1, and what to do about the warnings (should i find a custom kernel, do i need to backup anything else, I read also that the recovery I have doesn't backup efs, so how can I do that?)
Thanks a lot for taking your time to help me out.
@milen_506
So when you reboot into recovery, you have philz recovery?
If yes, all you need to do is install a newer recovery such as the one from this post. Once you flash it, reboot straight back to recovery(you will get a bootloop if you try to reboot into the system). This newer recovery is compatible with the latest versions of android and gapps, so just need to have the rom .zip and gapps(if you want play store/services) .zip ready to flash before you upgrade this recovery. Do a nandroid backup before you flash the new rom/gapps
There are several ways to backup efs, HERE is a link to one option
And as far as custom kernels, you are probably better off sticking to the kernel that comes with the rom unless you are comfortable adjusting kernel settings and you know what you are doing. It would be easy to mess things up if you didin't have a basic knowledge of the changes. Also with cm12/LP roms on the S2, custom kernels are only starting to be developed and are a little unstable for some users at this stage.
Hi,
Just got my phone back from servicing.
And now it has a stock recovery 3e and some Stock JB rom (not sure if its rooted or not).
Thing is, i've read like 7-8 different posts on flashing a new Rom, or Kernal or Recovery, but no complete guide to explaing the proccess, and now i'm scared to flash anything from fear of bricking my phone.
I want to flash an official Samy based JB rom (i found one) , but do i need to flash a custom recovery/kernal first (like PhilZ CWM?) or other way around ?
Any help is highly appreciated
The chances are that Samsung have returned your device to fully unrooted stock.
There are root checker apps on playstore that can confirm this.
If you are un rooted, the easiest way to get root back is to use PhilZ kernel......you simply flash it using the stock recovery. With regards to what you *want* to flash.......
You need to provide more details as to what the rom actually is, where it came from, what file format you downloaded the ROM as......that sort of thing....
Hey tnx for replying
Yes , you were right.
I flashed CWM via Odin (worked, but i got the yellow triangle now) sign.
After that i did this : http://forum.xda-developers.com/galaxy-s2/orig-development/repartition-memory-s2-t3018749 , worked
And then i installed an Samsung based JB 4.1.2 rom standard via recovery.
all works well now,i think, just booted up 2min ago.
Phone can see all my internal storage space and sd card,think all is well.
Did i do it right ?
It sounds like it, except that you probably didn't need to repartition the device......If you'd been flashing a lollipop rom, then the repartition would have been necessary, but not for JB......
Incidentally, what is the name of the rom you flashed? As Sammy stock roms can normally only be odin flashed.....
I realise that, but the extra space for apps sounded really nice.
I installed this one : http://forum.xda-developers.com/galaxy-s2/development-derivatives/rom-custom-stock-rom-5-0-edition-t2076568
