[Question] Kernel flashing and matrix kernel specifically. - Nexus S Q&A, Help & Troubleshooting

Hello everyone!
Phone: nexus s 3g running stock 4.0.3 with matr1x 14.0 kernel
my 1st question:
i was wondering how can revert back to stock kernel without flashing my stock rom again or going back to my previous backup?
i know it is very easy to switch from kernel to kernel but i would like to know how to switch back to my stock kernel. If you come across a link please send it to me. Thanks much appreciated.
my 2nd question:
my phone reboots the 1st time when loading up matrix kernel.
what happens is i press the power button .. the phone boots up normally then halfway through the animation it gets stuck and the phone reboots BUT this time the boot animation works properly and i am finally booted to my phone. Note that i have absolutely no issues running the kernel + BLn + Voodo etc (also not oced either)
question how can i solve this? is it normal?
I have one last question (sorry lol)
about voodo colour is there anyway of removing the grren flash that i get from unlocking the phone.
i know i can reset to 2.3.3 colours and that does do the trick but i would like to use my own custom settings..

stock 3.0.8 kernel can be found here in 3rd post
http://forum.xda-developers.com/showthread.php?t=1399273
Questions regarding matrix should be asked and may already be answered in his thread
And green flash is common on kernels with voodoo it also turns screen green occasionally for me when auto brightness set
not sure how to fix haven't researched doesn't bother me that much

Alright...
First off is this a specific rom? Like kustom kream, nexus beam..
Or just stock ics rooted
Second, try this again.
Get the rom zip again, then get the kernel zip again.
1. Wipe data, cache, and dalvik cache
2. Flash rom
3. Set up rom
4. Go back to cwm
5. Wipe dalvik cache
6. Flash kernel
7. Reboot
Did you do it like that?

Green flash can be fixed by downloading the voodoo control app in the market then going to the RGB profiles then selecting the voodoo profile

Green flash can be fixed by using either 2.3.3 colors or punchy

im on offical ICS 4.0.3 rom stock (rooted) with matr1x 14.0 CFS
well i downloaded matr1x through rom manager and after wiping dalvik cache i flashed the kernel.
is there anyway of fixing without clearing data? i have a lot of stuff on my phone i would rather not erase... also im on stock ICS so how would go about flashing it again(its not like a rom i can just dl and install or is it)?
speaking of which i know titanium backup backs up apps but does it also backup like my contacts, sms and phone settings etc?
update: i went ahead and only deleted cache and dalvik cache and then installed the kernel again. same problem =/

I'm 17! You want to teach me the basics of modifying roms? How'd you learn? The reason I'm asking is I'm gonna major in computer engineering at Drexel University in Philadelphia. I know Java already.

exact same problem ....
followed ur steps perfectly.
anyways i just restored everything back.
wow your 16 !
im 16 aswell i dont even know the 1st thing about making kernels and so forth lol.

Lol sorry you couldnt get it to work...
The only other suggestion I have is to try another rom...
Sent from my Nexus S using XDA App

thanks for trying .
anyways the thing is the kernel works perfectly fine other then that and sinc ei dont reboot my phone so much its really not an issue for me.

just another quick thing since that is the only problem i have experienced with the kernel and that everything else is fine working fine should i be worried about stability?

No, the kernel is pretty stable out of the box.

[Q&A] Miui For Infuse Rom

Notice:
This thread is for general questions regarding MIUI FOR INFUSE ROM.
sticky please
I flashed miui about a week ago. The .30 edition.
Well I want to update and when I try to boot into cwm it just sits at Samsung screen.
I tried to flash the cwm through Tom manager and still nothing. =\
I was having the same problem booting into cwm. I followed LG_iiNsTiiNcT's directions that are below via the2rrell and I was able to boot Jordan's update. Thanks guys.
the2rrell said:
i have seen 2 fixes for this...... this is one of them from "LG"
Okay so if you were one of the few people who lost recovery for some weird reason "ME" no need to unbrick to stock and re-flash I have a solution.
1: Download sgs kernel flasher
2: Download CWM community kernel
3: Flash kernel via sgs kernel flasher "unchecked the reboot button" when done flashing turn phone of "SHUTDOWN"
4: 3 finger until the Samsung logo pops up keep holding the buttons the screen will go black then Samsung logo will come up, let go of the power button and keep hold the volume up and down buttons "For about 20 seconds" then let go it should boot into Red CWM after a few seconds.
5: Go to install zip from SD card go all the way down and run update.zip it will boot back into RED CWM run update.zip again and it should now boot into GREEN CWM
6: From here Re-Flash MIUI "New Release would be smart", Wipe Fact,Wipe Cache, Wipe Dalvik, Flash, reboot at sign of Samsung logo pull battery, 3 finger into blue recovery and flash again.
7: Presto you should be set and have recovery back.

Well I had great success with 1.9.23 and 1.9.30. Read about all the people having issues with CWM and laughed thinking they obviously did something wrong. Well lo and behold, updated to 1.10.7 and now I have no recovery. Gah! So what is my recourse? I flashed exactly as I did before so it wasn't user error. Anyone have a clue as to how to get Recovery back?
Voo-Doo??
I've ready everywhere about this rom but I cannot find the answer for this!
Do I need to turn off Voo-Doo lag fix for this rom??
Thanks

Charging and Kernel question.

Since upgrading the CM9 kernel to a custom one, my phone will not boot once shut off unless I clear cache and dalvik. Is this remotely normal?

Sent from my Nexus S 4G using Tapatalk
Try reflashing the kernel first and see how it goes. If that doesn't work it is probably best to wipe everything and reinstall.
i had a similar issue with matrix 14.5...it would boot loop unless i cleared the caches...i played around with the voltages and governors for awhile..and it was ok for a day or 2 then it started it again...so i ditched matrix and went with speedy 5 and i havent had a problem yet...

Your phone can't handle undervolt. That's the problem.
I use matr1x, have done since gb days and have never had a problem so its definitely just your phone.
Thanks for all the replies, just went back to stock. Can't have my phone acting up now that I am working. Will reroot once the update to ICS happens on Sprint.

When you really make a clean install of rom and kernel there shoudn't be such problems.
When changing KERNEL always follow this steps !!
1) CWM format /system and /cache
2) go to advanced menu, wipe dalvik.
3) Then reinstall your ROM, then flash kernel right after.
No data loss, system exactly as you left it, only difference is new kernel.
If you are switching to a different ROM, add format /data.

Problems with nexus s 4g

Every time I put my phone to sleep it freezes and reboots. Sometimes it'll reboot fine, others it'll freeze on the google boot screen until I pull the battery. I've tired 4 different ROMs from locked stock to unlocked Cm9 to baked and slimbean. I've tired dirty flashing. I'm out of ideas now. If anyone could help out I would greatly appreciate it.

Changing kernels is exactly like changing ROMs. You flash them, although, you have to wipe cache and dalvik cache every time you change a kernel. Look in the developer section for our phone, there are 3 kernel choices: Matr1x, Marmite, and Air Kernel. Test each out on different ROMs, find your favorite. Be sure though, if you're going to be hopping between Android versions (4.0.4 (ICS), 2.3.7 (GB), and 4.1.1/4.1.2 (JB)) You find the version of the kernel that corresponds with whatever version of Android the ROM you're using is running. As far as I know, Marmite is only available for JB, Matr1x has kernels for all versions of Android (GB-JB), and I think Air only has ICS and JB versions. Hope this helps!

Hi..
It either some junk files u have floating around ur SD card..
Or
Are u tweaking the CPU when u install the ROMs?
Or
Are u using titanium backup to restore any of ur apps?
Try to do the entire factor reset/ wipe both cache & dalvik but also flash a zip file call "wipe all" ( it formats everything under storage and mounts except the SD card stuff)
Then flash the newest slim bean 3.0 it comes with a good kernel
Flash it and do not add anything. Check if the sleep reboot issues still occur.
If not then make a backup b4 adding ur apps and restores since one of those can be causing it.
I hope it works... good luck

I feel like this ROM is taking a little longer then usual to install.
Upgrading from CM7 CWM 5. Been on the "installing update..." with about 80% done for about 10 minutes now.
I've never had this happen before.
Did a factory reset before upgrading.

FYI, make sure that you upgrade from CM9 to CM10 then to CM10.1... If you start from CM7 you can have serious problems, especially of your only on CWM 5... You should be on CWM 6.
It still may work, but its highly unlikely...

You must be on at least an ICS rom.
I actually got tired of waiting and pulled the battery. Turned the phone back on expecting to be f'd. To my surprise I was booting into CM10.1 Aries,
Not sure what went wrong but all seems OK so far.

Seems to be working for me.
When you say Device Settings are not working, does that mean everything in the 4.2.2 Device category in System Settings (Sound, Display, Storage, Battery, Apps, and Advanced), or just the SGS4G Settings under Advanced?
Before I update, does Adobe Flash works or not (if I reinstalled it)?!

I flashed from beanstock (TWRP) and got hung at the bootloader. I had to 1click to stock, get on CM 10.1 (CWM 6). Then flash Aries CM 10.1.
It looks like you need to flash from CWM 6.
