[Q] Flashing A Kernel - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi everyone; forgive me for the N00B question - I have been having a great time with different ROMs on the SIII - I have never before flashed just the kernel and am interested in trying out ktoonsez kernel. I just want to make sure that, should something go wrong or I'm not happy and want to go back to the kernel I'm already using, can I just do a restore from CWM? Not entirely sure if restoring through CWM also restores the kernel that was installed at the time of the backup.
Thanks very much.

Yes you can do one of two things. Restore a nandroid from cwm or reinstall the ROM your on. If you restore a nandroid you will lose any apps installed or changes made to your phone. If you reflash the ROM your on wiping only dalvik cache/cache then the oy thing that will change is the kernel, you will get back the one that came with the ROM.

I just DoD this with my S3 for the first time and it was.fairly easy. I was updating to a new Rom and flashed it right afterwArds. One thing to remember when flashing the kernel is to
Clear the cache and Calvin and then fix the permissions.
What Rom are you using?

Going from Blazer ICS Rom to AOKP ICS Rom

I have my rooted E4GT and the Blazer ICS Rom is installed on it at the moment. I kinda want to try and switch to AOKP's latest build and try it out, but I'm not sure how to go about doing that since they clearly stated not to flash from ICS to ICS.
Could anyone point me in the right direction as to what I should do in order to make the switch to AOKP?
Links to both ROM's respective threads:
AOKP Build 40
Phantom's Blazer Rom
Thanks for your time.
You can just Odin the el26 cwm (sorry don't have the link to it on my phone) and flash AOKP from there.

This is my method, it is 99.9% safe. You can also re-use it to go from other ROMs to any other ics ROM.
Download these drivers
Download this: OC ODIN File for EL26 and this: E4GT Root Utility
Using Titanium Backup, make a backup of all your stuff, or use your preferred back-upper, just not nandroid. I recommend buying the Pro version, because it will save you so many times, and the dev is great. It's a little expensive though for an app.
OC Odin back to EL26. The good thing about this is, the process is straight forward, and doesn't add to your flash counter, and does not yellow triangle either.
Open up e4gtauto-sfx.exe, option C, then I. This gives you CWM, And just in case, I do not recommend using other than standard CWM to flash ICS roms. but that's me.
When your phone reboots, it should have CWM, and be rooted, just load up the AOKP files, do a data wipe, and flash.
Thank you both for the replies
Would I be able to use calkulins format all to do the wipes? Or does that only work for certain ROMS? It seemed pretty fool proof when I used it, so I was wondering if I could just use that again and it would work just the same? I don't want to forget something and brick my phone as a result
And I'll look into titanium backup, thanks for the suggestion.

For ICS ROMs, I recommend to not use it, just do 1 system data wipe and you'll be fine.

Alright, but all I should need to do is install the EL26 + CWM and I can flash AOKP? I don't need to go back to a stock gingerbread ROM or anything, or will the OC EL26 CWM do that for me?
And you said you don't recommend calkulin's format all for ICS roms, but that's what I was told to use for the Phantom Blazer ICS rom when I was flashing it?
Also, one more question; what is "flash count" and is it a bad thing? I'll do some googling on it myself, but I'd like to hear your explanation because I don't always understand people's ways of describing things and usually take weird explanations to understand so yours would still be much appreciated just in case, thanks. ^_^

You just need to be on a safe recovery.... if you wipe data in an unconfirmed recovery you can cause a brick. Either use the el26 that all use or the el29-reboot kernel. Both will work no matter what you install regardless of you install (granted you flash a working rom). I prefer the el29 because you install via mobile Odin and it boots straight to safe CWM recovery.

Nandroid Restore Help

I'm new to Samsung Android phones, and new to the E4GT, so I need a little help.
I always flash the zip for the EL26 CWM5 recovery like instructed, soooo, here is my issue.
I'm running AOSP and thought I would try CM10 JB, soooo, I flashed into EL26, performed a full nandroid to my Ext SD. I flashed JB and gave it a shot. For issues known to all, I wanted to switch back
So, I went into recovery, flashed the EL26 recovery and rebooted recovery, I then restore the nandroid backup I just made, rebooted, went to the Samsung screen (with the yellow !). After some time, about 20-30 seconds, it goes to a black screen indefinately until I pull the battery.
Any ideas? I have yet to get a nandroid to work on this device. Had no issues at all on my 3D. I'm sure I'm doing something wrong.
TIA,
Tee Jay

Nope, won't even turn on. But if I do a full clean flash of the exact ROM, it works fine.
I'm by far no expert but I'd say the kernel is being replaced by the gb recovery kernel when you flash back for your safe recovery.I personally keep a couple various recoveries so I can nandroid backup on the kernel native to the Rom and then the backup will contain the proper kernel.I think I got that right.so....nandroid b4 recovery has been my habit.
Had this issue before, minus the yellow triangle....anytime you're on an aosp rom and do a nand via el26, the nand stores the last kernel used (which is GB el26). After you restore, wipe cache and dalvik and then flash an aosp kernel, probly one from chris41g. Reboot and should he good to go.

Right, I tried that with my AOKP backup, I was able to boot. But then my WiFi wasn't working because of something to do with the Kernel I'm assuming

Latest CWM?

I have been running AOKP ICS for a while now and I had TWRP as my recovery. Well after flashing around a bit I had to reflash a rom and was unable to inject TWRP for it to boot. As a result I have CWM 6.0.1.3 I think. Is this the latest and why would I have a backup fail to create a MD5, therefore rendering that backup useless? CWM seems fine for flashing and wiping, but backups are super important. Any help would be awesome!

6.0.1.3 is the latest and I know, it can't make a nandroid backup
If you want make a backup on CWM just back to 5.0.2.7
Or use TWRP, I like TWRP

I'm kinda in the same boat. I ran into this issue when I was trying-out CM9. Now I'm on CM10 9/14 Nightly, which installed with CWM 6.0.1.3. I'm ready to flash the NS4G modem AIO and give it a spin now that the roaming issue is fixed. However, I want to be safe about it and run a nandroid backup first. If I can't restore my nandroid using CWM 6.0.1.3, can I use 5.0.2.7 with CM10?
Can I just CWM flash 5.0.2.7 over 6.0.1.3 or am I better off flashing TWRP?
Thanks in advance,

Why does cm roms install a recovery any ways?!? I remember back in froyo rom days around hear. Some Devs *****ing about roms installing recoverys & apks to /data/ every one at that time came to agree that Roms SHOULD NOT INSTALL A RECOVERY.
I mean if a new cm rom needs a new cwm recovery then FLASH the new recovery reboot recovery & flash the rom

Believe it had to do MTD. Last I read about this, been a while, the 5.5 version of CWM was specifically for MTD and the 5.0 version was BML. I could very well be incorrect, but that's what I recall reading a while ago.
5.0.2.7 works on MTD
IDK I just miss having the cmw flashable cwm recovery zips. Luckely I have got gotten in to a pickle like many have

OK -- Now I get why I couldn't flash 5.0.2.7 over 6.0.1.3 when I was trying to get back out of CM9 a month or so ago. However, I ended up Odining back to stock and installed TPR MTD and I could swear that I ended up with CWM 5.0.2.7 on MTD.
I'm soooo confused.....
I just want to make a restorable nandroid of my CM10.

Yup. I've never been able to restore a nandroid using 6.0.1.3. I always get an MD5 checksum error. To be honest, I haven't tried in a while, but that was my experience a month or so ago when on CM9. I have no idea if the problem lies in the CWM backup or the restore process.
I'll give it another shot now to see if I can backup and restore my CM10. Stay tuned.

Well, Ahhhl be! (my best Gomer Pyle impression -- you youngsters can Google Gomer Pyle). I ran a nandroid in 6.0.1.3 and advance-restored data successfully. I don't understand what all the complaining is about....

Phone will not boot any kernel. WHY?

First a little background. I am not new to the android world whatsoever. I don't post much but have been lurking for years. I had a Verizon GS3 and just recently switched to T-Mobile a few days ago and obviously bought a T-Mobile GS3. My vzw phone had no problems. But for some reason my T-Mobile phone will not boot any kernel I try to flash. Roms flash fine but when I flash a kernel everything goes fine in recovery but my phone won't boot past the splash and I end up having to restore a backup. I know I'm flashing the right kernels. I am on touchwiz based ROMs and haven't tried any aosp Rom because for the first time ever I actually prefer an OEM skin to aosp. So basically am I missing something obvious. Anyone else having thus problem. On Verizon I had to root and unlock the bootlosder. From what I understand tmobiles bootliader was not locked down and all I had to do was root. Like I said. I've tried every touch wiz Rom and every touch wiz kernel with each Rom and none will boot past the splash screen. I always wipe dalvik and cache but even tried wiping data every time too and keep getting the same result. Any input would be appreciated. . Thanks in advance.

Shouldn't need to do any wiping of any kind. I only use AOSP/AOKP, though. May I ask why you even bother with custom kernels? They honestly seem like a waste of time to me.
Im just flash happy. Like to try them out. I've been on Verizon for many Years and am used to the developers over there. I'm still getting used to the devs over here. Don't know any of there work. I'm sure its all good though. Been using imoseyons lean kernel since the thunderbolt back in the day and have stuck with them. Just my personal preference. I'd like to try some of tmobolrs kernel devs work but like I said I can't get a single one to boot.

What kernels have you tried to flash? There are a couple that have ICS builds. Also, what version of CWM are you using?
I've tried all the tw kernels. Every single one with 2 different ICS tw ROMs. I'm not using the leaked jb tw. I'm stickung with the more stable ICS ROMs for now. I just don't understand. I've tried every one. I've been flashing a long time and don't get it. Im kinda new to Samsung though. First Samsung was the galaxy nexus. Didn't ever use Odin with it. Does anyone flash kernels with Odin. Maybe I should try that. And to answer your question I've tried twrp and the latest version of cwm from rom manager. And of course I'm using the ICS TW version of the kernels im trying.

It could just be your phone doesn't like them. There is another guy on CM10 and AOKP that can't get custom kernels to boot either.

The kernel source code was never released for any build from UVALH2 and beyond. So most of our kernels will only work with UVALEM and UVALG1 builds.
We got kind of lucky I think and ktoonsez att kernel was brought over and works. I think there's one or two others that work now too.
As far as described here go I think we've got some of the best! For an outstanding rom you should try FreeGS3. It works with most of the kernels and is an awesome stable rom. If you want a later build try wildcards XquiziT v70 based on UVALH2. Use ktoonsez kernel with it.
And just to note, the stock kernel is surprisingly good. So give it a fair shot as well. Though I can definitely see some potential advantages of custom ones as well.

Whatever you do................
Be sure to double check before you flash that kernel. Had my first SGS3 for 12 days before hard brick set in. Terrible disease it is.......! I had to adopt a replacement shortly after to cope with the pain of the loss. Back on my feet again now though and soarin' higher than giraffe vagina on the things I learned in my days off for mourning. I can tell ya I've personally flashed the lean kernel and kt-747 with no issues. My problems were with siya mainly.
Guys, I have a serious problem.
It's similar to the one of the thread-opener.
The diference is that I cant get ANY ROM to boot, WITH the stock kernel.
And i do like the guide says: wipe/factory reset, wipe chache, wipe dalvik cache and then flash the ROM.
Everything works fine til the ROM finished flasing and runs a reboot.
My S3 shuts down screen, then turns screen on with the "Samsung Galaxy SIII-GT-I9300" and then thats it!
All i can do is to go in download mode or recovery mode. I can also flash CWM and so on, but after flashing ROMs it won't boot!
Is it possible that i broke the device by formating internal sd-card with the stock recovery tool?
Did it, after I tried to install Wickedv6 ROM and after both times when it rebooted it just reinstalled stock ROM. So i thought, ok delete the internal sd-card, so no stock ROM on it any more.
Also tried this ROM: http://forum.xda-developers.com/showthread.php?t=1875923

Also tried to fix the problem by rooting and then flashing ROM. No help.

I did the wipedata, cache and dalvik, i wiped everything needed, i followed all standard directions for flashing new ROMs, but nothing works. And oh, im using CWM recovery and on rom manager it says im at the latest version, so everything is up to date and everything should work but it doesnt:crying:
I had same issue too. It never worked for me if I switch from CM to PACMAN ROM. But I had it working if I flash stock ROM first then flash PACman. Any stock based ROM should work. Its a pain but you should try it. Also I used TWRP and I always wipe system too not just cache, delvik, and data. Just make sure you have nandroid. Good luck.
Edit: also I never flash PACman ROM and gapps together. Flash ROM let it boot once and go back to recovery to flash gapps..
