best way to revert from obsidian?

i have a nandroid of ji6. do i just apply that and flash a ji6 kernal? can someone link me to one if so? if not, can someone explain how to do it? thanks.

I believe you have to ODIN the official JI6 release (you can find it in the dev forum). Then you have to root, install ROM Manager, and nandroid your way back to where you were.
The key is to Odin a Rom, any Rom, that has the JI6 kernel.

Odin JI6 and then nandroid.
Nandroid doesn't install the kernel, so you would end up with a "brick" if you tried to nandroid on a 2.2 rom.

thanks guys! loving obsidian so far, but i think i need the signal strength boost from ji6.

Nope, I was on Obsidian and just flashed straight back to Bionic Fusion through clockworkmod recovery (straight, not through ROM Manager), and then Core kernel on top of that. I'm running perfect apart from slow market downloads (mostly my fault I think--accidentally deleted some system apparently and then restored; downloads work, but fussy)

that's because bionix flashes the kernal along with the rom. nandroid doesn't. that is why i asked if i could just flash the ji6 kernel after restoring my nandroid.

ATTN: Don't give advice if you don't know what you're talking about.
On to the post:
You can feel free to nandroid or flash to/from anything. However, if your Obsidian install is like many other peoples, you probably can't do crap in recovery. In that case, you need to Odin. However, if your recovery does work, just flash the rom and the kernel (or just the rom, if the kernel is included)

OK ill give it a shot if I decide I don't like obsidian. Thanks.

By can't do crap do you mean can't flash or can't access clockwork mod? (I can boot into clockworkmod just fine)

Ah, sorry. I thought the issue was whether you have to ODIN back to stock in order to roll back from Froyo.

For me the safest was to ODIN JFD, then flash JI6.

Enlighten Me...

I'm running AOSP JK2 1.1 and I was wondering if I can flash the JI6 modem on this? And if flashing the modem is just like flashing a rom.
Also, if I flash voodoo lagfix, how do I undo it? Thanks so much!!!!!

Yeah JI6 modem should be compatible but don't quote me.
To undo Voodoo Lagfix simply put a file called disable lagfix into the voodoo folder on your sd card.

Thanks!!! And I'm assuming this "voodoo" folder will be present once I flash voodoo lagfix? And god forbid something goes wrong can I still ODIN back to stock everything if for some reason I can't uninstall voodoo or the JI6 modem messes it up?

I would stay away from the voodoo lag fix. It can cause alot of problems. Try one of Eugenes universal lag fix kernels. They're super fast, overclockable using set cpu and you don't need to undo the lag fix when you flash another rom.

[Q]Flash rom upon rom?

Hello,
Im now running PRIME 1.4 and there is a 1.5 version released.
I want to flash the most recent (1.5) upon the current (1.4).

Flashing Custom ROM on the Note. I have specific needs.

Hi,
I know there are dozens of threads around about flashing Custom ROMS on the Note, but I have specific requirements to be met before attempting to flash a ROM on my Note. Its not that I'm new to flashing ROMS, its just that since I know that the Note is the "most vulnerable" device when it comes to the emmc bug, I want to be on the safer side. My Note is just around a month old and I dont want to brick it due to any foolishness from my side warranty in India sucks, In simple words, even if I'm eligible for warranty, I would receive my Note in a scratched, scuffed and abused manner though in a "working" condition, God knows for how long after a freaking month or two. Well, thats warranty here in India. So, as my loss is my loss alone, I created this thread to be safe.
Coming back to the topic, I'm running Stock ICS DDLPA on Speedmod Kernel K3-7 and want to move to Paranoid Android 0.5 which I believe is a CM9 based ROM.
1) As I am on ICS (speedmod kernel k3-7), is it safe to flash a Gingerbread ROM via PC ODIN?
2) If the 1st one is a go, I do not want to increase my binary counter while rooting gingerbread or installing Paranoid. I know about TriangleAway but since it requires the CF Kernel, flashing many kernels(on the NOTE) freaks me out at the moment. So I just want to flash the ROM without any increase in binary counter.
3) In the video guide on installing Paranoid Android, I see that the person goes into CWM recovery in the Gingerbread Kernel and flashes the Paranoid ZIP file and GAPPS and then proceeds to Wipe Data\Factory Reset. But once the paranoid android ZIP file is flashed, isnt he on an ICS kernel? Correct me if I'm wrong.
4) I see that Paranoid Android uses the CM9 kernel. Is it guaranteed Safe to Wipe using this kernel? Does it have the MMC_CAP_ERASE disabled like the speedmod kernels?
5) Last, incase if I ever want to revert back to Stock ICS for any reason, is it safe to flash back to Stock ICS using PC Odin while still on the CM9 Kernel or do I need to flash the Stock Gingerbread first over the existing CM9 kernel?
It would be really helpful if my queries are answered in the same manner as I have asked above.
I have gone through all the warnings and guides here in the forum but none of them seems to specifically satisfy my needs. I would have just flashed away but since its a "NOTE" again, I really want to be on the safer side.
Thanks in advance.

Flash Abyss Kernel.
Reboot in Recovery (under advanced) <= important
Flash ROM
Flash Gapps
Full wipe (factory reset, cache + dalvik cache)
Reboot and enjoy.
To come back to Sammy ICS => PC ODIN

You're the first guy on this forum wanting to flash something with "specific needs". I wish you all the best. Good luck!

paranoid on android - galaxy note n7000

I'm sorry, all the issues which popped up lately regarding the emmc bug as kept me on stock till now. If that nasty bug wasn't there, this thread wouldn't be there in the first place. I've never run on stock on any of my phones and this is the first time that I've stayed this long on stock. Its not that I'm new to flashing or anything. I've been doing that since the Symbian and WinMo 6.5days. Its just that its a "Note" and I wish to avoid a brick anytime soon.

But why not just ask in the ROM thread. I am sorry, but every day someone opens a thread which could - looking at the very specific needs of everyone - just be handled as a post (in your case in PA by imilka) instead of its own thread.
Nevertheless I am glad to see that you informed yourself.
If you felt better, then install one of the per rooted GB Roms.

1.flashing stock rom with pc odin is safe. Irrespective of rom you are having.
2.flashing stock rom.doesn't raise flash counter.
3. B'coz it now running on cm9 kernel which is safe.
4.yes emmc erase cap driver is.diabled, but.if you talking in terms of 'guaranteed' then even developers also not using this term still on ics
5. my answer 1 hav already answered this.

Trust me I was just as cautious as you are. But as long as you use a safe kernel, reboot recovery and then perform 3 wipes you will be fine.
I'm pretty sure speedmod is a safe kernel. Someone correct me if I'm wrong.
Good luck!! I go through more roms on my phone then I do underwear haha

If I flash Abyss Kernel using MobileODIN, I wont be able to boot into my existing ICS ROM as it is a gingerbread based kernel, am I right? Then, how do I confirm I'm on Abyss Kernel while in recovery?

Thanks for your quick reply. To be frank, I wanted to hear from you as I've seen all your guides.
My question no2 is not about flashing stock rom but will rooting the stock gingerbread with custom recovery raise counter? I do not want to increase the binary count. Would flashing the above mentioned AbyssKernel also do the job?

If you follow my guides to root gingerbread it won't raise counter. In my guide i have never mentioned any procedure which can raise counter.
Just one suggetion, if you want to flash gingerbread as only for switching purpose, then go with prerooted rom(find from my signature) and flash using pc odin. After flashing you will have gb rom +root+cwm

Is there any complications flashing the AbyssKernel instead? Is it safe to flash with MobileODIN? Would it increase binary counter as I'm moving to a Gingerbread based custom kernel from ICS?

If it's completely stock, it won't increase your binary counter, also flashing kernels is 100% safe, even with the emmc bug.

No, unless you reboot right after flashing the rom, you're still on whatever kernel you used to flash, also CM9 kernels are safe.

Yes, but keep in mind stock ICS has the bug, so unless you're using a different kernel on it (SpeedMod, etc), you're not safe.

There's a galaxy note website, not sure I should mention it or not, where the guy uses abyss 4.2 all the time to "safely" flash new ICS roms. He flashes this kernel in recovery and then advance reboots into abyss recovery. Once in recovery he does the dalvik/cache wipes and factory resets before installing an ICS rom. I guess he uses this method as a way to avoid using pc odin to save time.

Thanks a lot for all your support guys. I'm running Paranoid 0.5. The black clipping\crush is worst on the CM9 kernel and its everywhere. even in the UI. It really bothers me.
Could anyone suggest me a Good kernel with the least clipping and also any "Visually Pleasing" ROM (like MIUI) for the note? Paranoid looks mostly stock as its CM9 based but the tablet mode is just brilliant.on the Note. Its like the best of both worlds.

[Q] Flashing different Kernels - Nexus 4

I am currently running a Nexus 4 with PARANOIDANDROID 2.99b+ (Feb03) flashed with the Franco r53 kernel.
I wanted to try out the Matrix 6.5 kernel on my phone and was wondering if there is any step that I need to perform before flashing the new kernel. I found the following post that includes a cleaner script: http://forum.xda-developers.com/showthread.php?t=2121701
I was wondering if this is required or if we can simply flash the matrix kernel over the franco kernel. Would that be possible?
Also, would it be possible to flash the new PARANOIDANDROID release (assuming it includes a kernel) then flash the matrix kernel over that? Would this cause problems because the cleaner script was not run before flashing the new rom which has its own kernel?
Was not sure how it exactly works and was hoping that someone would be able to help me out and clarify the process.

Currently, I think your safest option is to flash the newest version of the PA rom and gapps and then flash the kernel that you want. Because a lot of the kernel developers are are making changes to things that may not be overwriten when flashing a kernel from a different developer. For example I think that franco makes changes to the ramdisk that some other kernel devs don't touch.

Cool, so I guess when we flash the rom and gapps it resets any changes that may have been made by Franco's kernel (or any other kernel for that matter). Hence, running any cleaner script is not required. Is this true?
Also, when flashing the kernel I wipe cahce, wipe dalvik, flash kernel, reboot. I read in another post that you should let it run for 10-15 minutes then reboot again to let the kernel "settle in". Is this actually required?

if you are running franco kernel, you want to either reflash your rom then the kernel, or flash the roms boot.img then the kernel. coming from other kernels, just flash the new kernel on top. the reason being that franco kernel uses its own ramdisk(and you want your roms ramdisk).

you do not wipe anything when flashing kernels, there is no need. wiping cache or dalvik has nothing to do with kernels, its just a misconception that keeps getting passed along.

Awesome, thanks for the info. So I guess it is a safe practice to flash the boot.img (or just update the rom if you were going to anyways) and then flash the kernel.

yup. i tell people to just reflash their rom(and gapps) with the kernel, then reboot if they were running franco kernel. but its safe to flash the stock or your roms boot.img also, then the kernel.

I am not sure what you meant by that.
What I get out of all of this, is that if I want to try a new kernel this is what I should do in recovery:
Factory reset + wipe cache + dalvik cache
Flash new rom (PA rom in my example)
Flash gapps
Flash custom kernel if desired (Franco's kernel in my example)
Reboot
Is that correct or am I missing a step/doing something extra?

You might notice if you update your ROM (e.g. the next time PA gets updated, or if you switch to CM nightlies) that during the flash, the kernel will be overwritten - no matter which kernel you are using.
For example, flashing CM installs the CM kernel - regardless of if I was running Franco's before that. This is why apps like CyanDelta (which supports incremental updates to the ROM, but also the flashing of zips *after* flashing the ROM) are so handy. Every three days, I flash the latest CM nightly, and then Franco's kernel. If I left Franco's kernel off the CyanDelta list, the phone would be using the latest CM kernel after the flash.
EDIT: Your steps look good, if not a little bit overly protective. For instance, I don't think a full factory reset is required to test out a different kernel, generally speaking. Obviously, it wouldn't hurt to do... just takes time.

That is pretty cool. Would that same app work on the PA rom or is it just for CM nightly builds?
Yeah, I am doing the factory reset because its a new version of the PA rom. I prefer not to simply flash over my current rom.

If you're running the latest PA on a mako, just get their 'contrasty' kernel and no need for your voodoo rituals

Only if you have franco now and switch to another kernel. So if you want to flash franco you don't have to wipe anything.
