[Q] Installing a custom rom without flashing the kernel? - Galaxy S II Q&A, Help & Troubleshooting

Hello, have been lurking on this forum for a while but never actually made any posts until now.
Let me start off my saying that I am a beginner when it comes to installing custom ROMs, I have only done it a few times before. I flashed my kernel, installed CWM and a custom ROM. After a while I got tired of the rom and decided to go back to Gingerbread 2.3.5. I hated the yellow triangle that shows up when using a custom kernel, so I went ahead and changed that back to stock as well, and that removed CWM as well.
But I've just discovered a ROM called "Batista70 Foxhound Edition 3.0" (which you can find in the i9100 general android dev section) and I love the look and feel it has, and would like to install it on my phone.
My question is pretty basic and simple:
Can I install this ROM without actually flashing the kernel (to avoid the f*ing annoying yellow triangle)? Or perhaps there is a way of flashing a kernel without getting the triangle? Though I'm not getting my hopes up for that question.
I also have a related question:
Can I install CWM without flashing the kernel?
Anything I forgot to add, let me know.
Regards,
Dimergon

If you by a jig off eBay for a few bucks all your problems will go away. It gets rid of the triangle and resets the flash counter. Well worth the $3.
CWM is within the kernel so to use it a custom kernel is required. CWM is worth having for backups and simple flashing.
My suggestion. Install one of chainfires cfrooted stock kernels. Use the jig to get rid of triangle. Then backup via CWM incase you want to go back at some stage.
Then flash foxhound.
Hope this helps.

What you could try is rooting it with zergush exploit. Then download mobile odin from the market, flash cf-root true mobile odin and then you have the recovery needed to flash. And no yellow triangle.
Don't know if it's possible, because I never tried it. But we are on a developers forum after all.
You could of course just flash the CF-root and then remove the yellow triangle with instructions from the CF-root thread. Or buy a jig.

Buy a USB-Jig from Ebay its a good investment and helps you on the triangle.. then download the old Bootloader and save it to your pc and then you are safe

All you need to remove the triangle is a zImage from a secure kernel it's all on the cf thread.

Thanks for the replies. I will definitely have a look at the USB jig, seems like the way to go.
And, to the reply above, is it possible flashing a secure kernel after installing a custom ROM? Seems to me this will not be without complications.

Cant boot into CWR

I got my bell s2 rooted and removed the triangle. Rom manager seem to install the CWR. However, when I boot using the volume up, power, and home button, I always get the android 3e recovery mode, not the CWR. What am I doing wrong? How can I get into CWR to install the cognition rom? THANKS SO MUCH!
I would really appreciate if someone enlightened could explain this as well. I thought cwm wrote over the stock recovery? Its happened to me a few times and I've even had to flash with the damn PC at the convenience store via Odin (I'm a Mac guy) just to get into cwm to restore. If your in the actual stock recovery just three finger salute instead of reboot. Should carry out the command too can't wait to sell this thing and get the nexus. Great phone, just hate Odin and love fast boot lol

I think i read somewhere that rom manager isn't compatible with s2.. Better flash cf-root by chainfire, it is pre rooted and has cwm installed..

It sounds like you've lost root trying get rid of the triangle. Reflash cf root kernel, install your rom then buy a jig to remove the triangle. Jigs are as cheap as chips on ebay.

Don't use rom manager, simply flash the cf-root kernel and you'll have your cwm recovery.
I finally got it to work, thank you to all who posted!
Now I installed a custom rom on and now my samsung apps store is missing! anyone know how i can get it back?

Dumb Question - On UnNamed. Going to ICS. How to prevent triangle?

Sorry about the stupid appearance of this question.
I flashed to unnamed last October and I bought a JIG to remove my yellow triangle and reset the counter. It worked.
I read that the new ICS roms disable the JIG ability and the counter gets updated.
I'm planning to flash to either CM9, Phone Bricker, or ShoStockv2. When I flash to those roms, how can I do so without updating my flash counter?
I tried reading the guide, but I'm confused as to what exactly I should make sure I do. The guide looks like a normal flash.
As long as you flash from CWM it won't trigger the count or triangle. Flash just like a GB ROM, no special prep. Only the odin-one-click of the leak has a bootloader (that is what causes the jig to stop working). The zipped ROMs won't have a bootloader.

As long as you don't flash boot loaders you'll be triangle less. Check out the mobile Odin thread also.
Also, TriangleAway (free on XDA, paid on Market) will nuke the triangle if you're on ICS.
Doesn't work when running GB.

I bought a jig to prevent the triangle after it popped up. I flashed a ton of times with CWM it has never revered its head. You're fine and I'm on ICS now. Like others said just say no to new bootloader
Sent from my SGH-I777 using xda premium
As long as you don't flash any of the newer 1click which flashes the boot loaders like uckk6 and newer you should not have any issues. I went from unnamed 2.2.1 to fakerom than to shostock rc2 than up to rc3, rc4, rc5 and v1.0 with out any issues! Plus shostock does not flash any bootloaders in fact I am still running uckh7 2.3 bootloaders.

[Q] Question to all devs and fellow community..

would it possible to create an automated script that roots your existing rom like what this genetlemen sfhub has done over there in the ept4g forum...this avoids upping the counter and the birth of the yellow triangle..
http://forum.xda-developers.com/showthread.php?t=1342728
or a one click odin..im guessing he took a tar that is completely stock and just added root, everything is basically automated after opening the .exe ...you guys can check that out here
http://forum.xda-developers.com/showthread.php?t=1694695
I brung this to attention so maybe someone could get idea to hopefully bypass upping the counter and the entrance of the yellow doom
Upping the counter isn't really an issue, we have a reset for it, and also a way of flashing CWM without upping it. And once you have CWM, you can flash ROMs without upping the counter. And the yellow triangle isn't doom, it's just a form of download mode where you can still flash back to stock using ODIN and give it another go. The process of rooting is already pretty simple, all it takes is flashing CWM through ODIN and then superuser through CWM. That process is good to learn if you're coming from stock anyways, as it gets you used to using ODIN and CWM. Also, unless you're on stock, the other ROMs are already pre-rooted when you flash them.
Sorry, not trying to rain on your parade, just saying it would be work for a developer that isn't really necessary. Who knows though, maybe if one of them wants it they will build it.

[Q] Can't change kernel?

I've been flashing roms a while now but have not encountered this problem. I can only flash roms with odin because i am not rooted, and i cannot root my phone. I am stuck on XWLPD kernel, no matter what kernel i install it never changes, why's that? Whichever ics rom i install the kernel never changes and stays XWLPD. I tried to root that so i could install a custom rom but then i get the yellow triangle and reboot and no superuser, no cmw manager and no root permissions, and kernel remains the same. I cannot downgrade to GB either as it just gets black screen after odin download mode and stays hot. I've searched through these forums for all sorts of solutions but to no avail, thus making this thread. Any help would be appreciated.
Could you state what you exactly did to change the kernel? And also you should have posted on the Q and A section
Sent from my GT-I9100 using xda premium
My bad. I should have. I came off from the Vk rom when everything was fine, and i decided to go back to a non custom rom so i used odin to install one of the released 4.0.3 roms which had the XWLPD kernel. After that, i couldn't root anymore, ater installing the cf root for the respective kernel i see the yellow triangle like all's well but when the phone boots up it isn't rooted. So then i tried installing another official rom XWLPF, installs and works fine, but kernel remains XWLPD, and it's like that for any other rom now. Going back to GB just shows black screen after the samsung sign.
Basically, i just can't install cf root anymore. Or change kernel.
After installing cf-root. Have you tried going to recovery and flash another custom kernel like siyah?
Sent from my GT-I9100 using xda premium
In doubt you could always flash back the recovery image from cyanogenmod wiki, and flash cm7 after. That way you're sure to get a fresh start and everything should work fine after!
It had a problem with my phone and this was the easiest way out.
Good luck
Sent from my GT-I9100 using xda premium
Thank you
Thanks guys. I managed to find a work around this rather unusual problem. I installed cmw from external storage, along with root, and changed rom from there. I couldn't change kernel, but atleast i changed roms. So i can live with that. Again, thanks.

HELP! Bricked my phone :(

Hello.
I've flashed the latest Siyah kernel (4.1.5) on my stock GingerBread 2.3.4, using Mobile Odin, not knowing that this version of the kernel is not compatible with Gingerbread, and ended up bricking my phone.
Now when i turn the phone on, I get the usual "Samsung Galaxy S II - GT-I9100" initial screen, then the eye logo of Siyah kernel, but after that the screen goes black and android does not boot.
I've tried Vol Down + Home + Power button combination a few times, even after removing the battery, but it looks like there's no way to even get into recovery mode, because the screen remains black. :crying:
Will I have to buy another phone, or is there any chance to save it?
Pleeeeease help me, I'm desperate!!
SOLVED
I finally maneged, I don't know how, to get into recovery mode, and I could flash back the stock firmware using Odin. PHEW!!!
My apologies for having opened this thread.
Recovery is both volume and power not home and power

In fact!
The post I read which was saying that it was that 3 keys combo must have been wrong...
btw... I'm so happy I could recover the mistake! I have also successfully re-routed my device with the old good doomlord exploit.
What I wanted to do was to install the latest stock ICS and have it rooted without triangle and counter issues, keeping a nandroid backup of my current rooted GB 2.3.4 in case I won't digest the well known ICS appetite for battery. I have rooted my phone using doomlord exploit, therefore currently I have no triangle and my counter is 0. Also, I've read that a full wipe of the phone is highly recommended before upgrading to ICS.
So my plan was:
To make a backup of all the apps, contacts, SMS'es, etc, using a few free apps available on the market, since I've read somewhere that, I don't know why, Titanium Backup can't be used in this case.
To install Siyah kernel in order to get CWM, with which I would have made a nandroid backup of the phone (but here I made the mistake of flashing the wrong kernel version).
To Download latest stock ICS ROM, and flash it using Mobile Odin, which would allow me to make a full wipe and inject the root permissions into ICS without triangle/conter issues.
To reinstall all the apps and reconfigure the phone using the backup made at point 1.
Do you think that the procedure should work, provided that I use Siyah kernel 2.6.14 (which is the latest compatible with GingerBread) at point 2?
Or perhaps it would be better to simply use Odin for PC, root ICS using CF-root, flash back ICS stock kernel (which would remove the triangle but leave the root permissions set), and then use triangle away to reset the counter? (but is triangle away actually capable of resetting counter, or all it does is removing the triangle?)
Since you are in Venice, I assume that you have the GT-I9100 or similar model. If so, you are in the wrong forum. This forum is for the AT&T SGH-I777 model, (US carrier) version. You should go to the I9100 forum to ask your question. And when you do, please post in Q&A, not the general forum. I asked a moderator to move this for you.

Flashing a stock ROM will not cause Yellow Triangle or increase your binary counter.
So you can follow below steps after you get all required backups using apps:
- Flash 4.0.3 stock ROM using PC Odin.
- Root using the method mentioned in http://forum.xda-developers.com/showthread.php?t=1501719 if you are concerned with Yellow Triangle and binary counter.
- Flash latest Siyah. Use Mobile Odin if you are concerned with Yellow Triangle.
- Flash any custom ICS or JB ROM.
Just follow first two points if you only need stock ICS with root. Factory reset is not mandatory but recommended so there are no issues later.

Thank you acekay. Now it's late but I will check the thread you linked. It looks promising!
Btw I think I must pay attention not to flash custom kernels or use CWM if I upgrade to stock 4.0.4, since I have the buggy eMMC and so would risk to brick the phone, wouldn't I? In such case I would try upgrading to 4.0.3, just to be safe.

Yep. 4.0.4 and CWM recovery is risky. 4.0.3 should be fine.
All the best.

If you flash custom kernel after upgrading to ICS 4.0.4, you are 100% safe!
the emmc bug itself is on the stock 4.0.4 kernel not the firmware as a whole

Ok. So the only thing to take care of is not to have both the stock kernel of 4.0.4 and CWM installed at the same time. All the rest is safe. Thank you for having made that clear.
