[Q] Can't change kernel? - Galaxy S II Q&A, Help & Troubleshooting

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

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?

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

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.

[Q] Installing a custom rom without flashing the kernel?

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.

Help! Tried to root after offical ics, now hanging at samsung loading screen.

My phone wont boot now.
It stays stuck at the 2nd Samsung during the boot up.
What happen was I updated today to offical ICS from my rooted gingerbread.
I updated via kias today to get official ICS, got it working and I noticed I didn't have cwm install anymore, so I followed this http://forum.xda-developers.com/showthread.php?t=1504218
It is pass it did it reboot thing, and never got past the 2nd "samsung" loading screen.
Anyone know how to get my phone booting again?
Flash the latest ICS kernel
I am not sure how to do that without cwm.
Before I updated to ICS when I press power + up down, it booted into CWM. Now when I do that I boots into Android System Recovery <3e>
EDIT: Good news.
Got CWM through installed though odin and then I restored to my gingerbread backup I made earlier.
Flash your roms via clockwork recovery mod from now on.
Drop the ROM .zip on sd card and then enter recovery. Wipe everything three times each then flash a uclf6 based ROM. Never touch Odin or kies again. Be happy. Ice cream sandwich is way better than ginger bread

Had the same exact problem. I "believe" the problem was that the CWM I flashed was perhaps incompatible with the official ICS?
I used Odin to flash cwm 5.5.0.4 as suggested and the fone was shut down with the hanging Samsung screen as you mentioned. I used the DL screen with Odin to the 600mb Team Objection ROM, which at least got me up and running again. I found out that CWM did in fact flash once the ROM was compatible with it. Updated CWM, then to finally get full stability, I had to do a factory reset after clearing both caches, then install the CM9 official.

Update: I installed official ICS again last night, looks like I lost my root and CWM.
I don't want to mess anything up again, so could you tell me exactly what CWM file you used to flash so it doesn't hang at samsung again?
I was having the same problems but I think I was doing it wrong. How are you flashing the root files? I upgraded from Kies, then used Odin to flash cwm touch (5.5.0.4 I think), make sure to let the reboot and that it's actually turned on and you can see your homescreen. Once you do that, THEN flash the superuser 3.0.7 in cwm. Let the phone reboot properly and it should be okay.
I was doing the same without the reboots and that's what caused me to hang at the logo, but after the above it worked well. Give it a try. For anyone who needs to flash the T-Mobile radios also let the phone reboot and then flash it because I was having issues with that which was fixed by letting the phone reboot.
Make nandroids at every step in case it does hang so you can just restore and try again instead of flashing everything all over again.

I've also tried rooting my AT&T Galaxy Note I717 which had recently upgraded to ICS via AT&T/Kies and my phone is stuck at the Samsung boot screen. While I'm no expert with rooting phones, I had no problem rooting it when it had GB installed so I figured I wouldn't have any problems rooting it again. Is flashing the ICS kernel the best way to fix this? Where do I get the ICS kernel from and how do I flash it?
Details: After my phone upgraded to ICS 4.0.4 kernel 3.0.8 (IMM76D.UCLF6), I followed some instructions to root it using Odin3-v1.85 and PDA->pda.tar. Other instructions used cwm-touch-i717-120414.tar.md5 and odin_n1717_cwm_recovery_b4.tar and I tried those but to no avail. So I have CWM v5.5.0.4 installed but I don't know what to do next.
Any help is greatly appreciated. Thanks!

Update: I restored my phone back to a non-rooted working Android 4.0.4 by downloading the stock ROM for my phone (I717UCLF6_I717ATTLF6_I717UCLF6_HOME.tar.md5) and uploading it using Odin3-v1.85/PDA. I didn't even lose any of my settings or data. Now I need to figure out how to successfully root it. But at least I'm not worried about getting stuck on the Samsung screen anymore.
Open odin , PDA cwm file, Droid in dl mode, plug in start unplug, reboot, go to cwm recovery mode and backup onto sd card.
Im learning more, as i soft bricked mine last time

You realize the reason you were stuck was because you flashed a GB kernel onto an ICS system? It would never boot. As the second post suggested... all you had to do was flash an ICS kernel to get it to boot.

I hope they go to the page I made and follow the green arrowed how to root ics...it is very super simple process to root the official ics...but ....
This happened to me after misreading a comment.
If you put your phone into download mode, plug it in, run kies, and do an emergency firmware recovery. You'll need the serial number. My phone is stock ICS again. Works fine.

so cwm 5.5.0.4 touch is a GB kernel? Because that's all I flashed after the KIES update to ICS and I got the hanging Samsung logo.
I believe some people are trying to get ICS rooted with this cwm and are getting stuck. Of course there are ways out of it, but it'll help the learning process if we can find the problem.

Won't boot into cwm/recovery

I've tried re-flashing a few rom managers via Odin (CWM, CWM Touch, TWRP) and it just seems the phone doesn't want to boot into them. I'm running the old h0twire CM9 build over ICS. I've flashed different roms and kernels with this version before, this is the first time I'm having any problems.
Gonna try going back to stock with Odin then start from there.
Anyone else have problems like this and if so, did you fix it?
Thanks in advance!

[Q] WiFi not working on JB ROMS

Just got a GSIII today and have been trying some JB ROMS out, but so far I have not been able to get WiFi working at all with any of them.
I have tried Vanilla RootBox, LiquidJB and SuperNexus but whilst I can see my WiFi AP on all of them and can enter my password all I get is the "Connecting..." message for ages before it gives up?
WiFi works fine on the stock ROM, and there are no obvious settings on the WiFi router itself which would be causing this.
Any advice appreciated!

Thanks, I just spotted a couple of threads mentioning this.
Couple of questions, when you say flash back to stock does that mean through CWM Recovery, or some other way? Does it have to be a straight flash to a downloaded stock ROM or am I able to just "restore" the backup I made?
Thanks again!

Cool, so I've got Odin (I believe that's what I used to root the phone?) Is there a specific .zip I need to flash back to? Also do I need to boot back in to the stock ROM or just stick JB straight back on again?
Please note, when you have flashed back to ics you need to then set up phone and connect to Wi-Fi once, then proceed to flash jb

Excellent. Do I need to download a specific "Stock ICS" ROM to do this? Any pointers as to where I can find this?
Thanks for the help people
I seem to remember I just flashed an old wannamlite Rom in cwm
http://forum.xda-developers.com/showthread.php?t=1646610
These ones. (4.0.4)
Or try http://fus.nanzen.se/
This is if you want to find the original firmware your phone came with.
I'm still not having much luck with this.
Should I be wiping before I flash back to ICS, and then again before back to JB?
I think a wipe before flashing ICS is enough.
But watch the youtube video on the first post on :
http://forum.xda-developers.com/showthread.php?t=1646610
It pretty much explains every part of returning to stock ICS. From there it is just reflashing JB with odin and wifi should work.
Hmm, still not having much luck. I've installed my JB ROM, wiped, gone back to stock ICS using the ROM from the link provided above in ODNI.
But now when I try to reboot in to recovery to re-flash my JB ROM I seem to get a different version of recovery from what I had before and it fails during verification when I try to flash the .zip.
Any advice welcome!
I'm having the same problem here.
BUT, even flasing stock ICS and flasing a custom JB ROM after that does not solve the issue.
Here is what I did in what order. Maybe I'm missing some essential point or whatever:
- full wipe in cwm recovery
- flash stock ICS via Odin (I9300XXBLH3_I9300DBTBLH4_I9300XXLH1_HOME.tar)
- reboot and test WiFi. WiFi works fine! Firmware is 4.0.4
- flash CF-Root-SGS3-v6.4 to gain root again
- boot into CWM Recovery, format /preload (to get rid of apps installing themselves on boot)
- another full wipe
- install zip from sdcard (tried AOKP JB build 4 for i9300 and ParanoidAndroid v2.22)
same old ****! WiFi not conecting!
I would apeciatie any help to solve this problem for me. Aparently reverting to stock ICS has solved this for others but I dont get what I'm donig wrong her...
try some router side adjustments

you need to root again flashing 'CF-Root' via Odin to get CWM recovery. I guess.

Okay so I Re-rooted with CF-Root through ODIN and have got CWM recover back, but now when I re-flash JB I still get the same problems, try to connect to WiFi and it just sits there saying "Connecting..." and then gives up!
Is there a specific set of steps for doing this? I connected to WiFi whilst back on the Stock ICS ROM (LG8) and that worked fine, I have tried various combinations of wiping/not wiping at each stage in between JB->ICS->JB with no luck. Do I need a particular Stock ROM to go back to, do I have to use a specific version of ODIN/CF-Root/CWM?
Very annoying as everything else about the Jelly Bean ROMS seems perfect!
Has anyone worked out why JB ROMS are doing this?
I have the same problem
It seems to work for some people to go back to ICS and then flash JB ROMs, but somehow it does not work for us..
I'm trying an old stock ICS now and the will flash cm10. lets see if that helps
I've downloaded a selection of stock and custom ICS roms to try with the process, hopefully something will do the trick!
Also I don't think changing router settings can have anything to do with this as it works fine for every other device I own, including a different handset running JB. However out of curiosity I spent last night playing with all the settings to see if anything would help. It didn't

You can flash any rom or flash the other kernel(perseus,boeffla,stock etc...)
if you want to go stock and unroot you need to flash stock firmware via pc odin... but if you want just to change kernel... there are a ton of options here in xda...
As to stweaks: You have to install that app from Play store, it is NOT included in the kernel since several versions as described on the Siyah thread.
