You will need to flash stock using odin
http://forum.xda-developers.com/showthread.php?t=731989
You are on the leaked froyo which had s recovery that will not allow you to flash custom roms.
You can find roms here in the development thread
http://forum.xda-developers.com/forumdisplay.php?f=706
Flashing roms is mainly done through clockwork recovery which us installed through rom manager which is a free app you can get from the market
As to which rom to use is a matter of opinion. Read threads, and understand the known issues. Most of the custom roms are great but there are short comings
If you need any further help feel free to pm me.

because recovery 3e which is what comes with FROYO by default, doesnt allow unsigned zip files to be used...which means you will not be able to use clockworkmod to install new roms...

thanks guys

alrite guys, finally i was able to flush with stock, did master clear and go it rooted with super user access.
when i did some research, thats what i found, whihc one sould i use, all i care if there is no ATT apps
* AOSP FroYo Beta Molecule http://tiny.cc/f7p1f
* VanillaCaptivate (AOSP 2.1): http://tiny.cc/fu3qc (still in alpha)
* COGNITION v2.2 BETA (previously SRE by Designgears): http://forum.xda-developers.com/showthread.php?t=786532

* Stock ROM (Odin one click): http://forum.xda-developers.com/showthread.php?t=731989

Or you could read about each one and select on for yourself.

Can you tell me how did it get the stock version?
I too had the same version but whenever I use the Method 1 from http://forum.xda-developers.com/showthread.php?t=731989, it always stays at download page and nothing is done on Odin. So I went with the steps mentioned on this page:
http://forum.xda-developers.com/showthread.php?t=818439 which still keeps the 2.2 firmware(btw mine is 1010 series)
Any idea on how to get back to stock version.
[update] NM abt this.. I figured it out. and choose Cognition..
Man, Cognition is awesome.. captivate is so fast and Quadrant shows 1500+ always.. Its time to donate to Cognition
I took this version: http://www.ponack.net/designgears/release/Cognitionv2.3b7-oc-uv.zip

[Q] need some help to tell my bootloader and basic root and CWM procedure

Hi all
I recently receive a 2nd i897, it's running fine but it's only a 2.2.1 (rooted and CWM installed already)
To get myself busy, I decide to upgrade it to 2.3
Here is some background from the setting page:
Model number: i9000
firmware version: 2.2.1
baseband version: i9000ugl2
build number: lidroid 1.9.3
And if i switch on my i897 from complete switch off state
I see "first" i9000 symbol, then i897 symbol
Because of this, i am not too sure what bootloader i am currently on.
My plan:
1.To flash this firmware from samfirmware - SGH-I897_I897UCKK4_UC_ATT (To get GB bootloader and clean 2.3.3)
2.To flash one of the GB kernels from http://www.semaphore.gr/downloads/captivate (To root and install CWM)
3. To flash my favorite GB custom rom
I wish to make sure if my plan is correct before going ahead
THX
Joe

It looks like u currently have an i9000 froyo rom and u have the i9000 froyo bootloaders.
I would suggest an upgrade to the GB 2.3.5 i897ucKK4 firmware with the Bootloaders and then flash KK4 Corn Kernel v7.0A to get the CWM Recovery that is included with that kernel (u can flash the .tar version of this kernel through Odin...use the PDA slot). Then flash ur rom of choice through the cwm. There is no need to get Root before u flash a Dev Rom.

Thx 4-2ndtwin
It looks like my little plan is align with your reply.
One more question, can i flash semaphore kernel instead of Corn kernel?
Thx

U can...But if it is not a KK4 based kernel then it will not boot ur phone.
If u try to boot up it will more than likely bootloop. U can use the 3 button combo to get into its recovery though. And then flash ur rom from there.
I would say, go with Corn Kernel.

hi guys
things didn't go too well.
30 mins ago, I just flashed UCKK4
from this link (http://forum.xda-developers.com/showthread.php?t=1357848)
Odin reported no errors, but now i have bootloop, I see at&t bootscreen
then a "3g" flying animation with white background.
Can someone guide me from here?
1. I think i need the proper way to get in recovery again
2. or to boot into download mode
Thx
Joe

don't worries guys
I have it solved

Cool. Glad u got it goin.

Can I flash a custom Kernel with stock 4.1.2.?

Hi.
I'm going to root and unlock my device this weekend. I can't settle on a ROM because I want a steady ROM and a really stable ROM. I don't want to be flashing every 5 minutes.
Basically I just want Voodoo sound badly on my device. I am running 4.1.2 at the moment.
Is it possible to flash a custom kernel with stock android?? I have read you need to delete a file before flashing on 4.1.1. Is this still the case on 4.1.2.?
Can anyone recommend a Kernel?
Thanks.

Yes you can do it. I suggest you to try Marmite Kernel v5, it's really smooth and it has a good battery life.With this kernel you can stay with your stock Jelly Bean 4.1.2, like me, and use a custom kernel (Idon't have to delete any file, I root my phone flash the kernel and gooo)

Wow thanks for replying.
I have heard many good things about Marmite .
So I defo don't need to delete anything from stock 4.1.2. Before flashing the Marmite kernel?

Nop, just flash via fastboot a custom recovery (recomend TWRP,link below) and root your phone with supersu or superuser zip.
then flash your kernel (dont forget to wipe cache and dalvik cacche before flashing the kernel)

Hi.
I was going to use CWM as I have used that before back in the days of the G2/Hero.
Would CWM be OK?

Yes with CWM no problem with flashing this kernel

Hi all.
Well today I gave it a go. I managed to flash my NS using the guide by gullu101. Everything went fine.
I have downloaded Voodoo app and have Voodoo sound at last! :good:
I also flashed Marmite kernel V5, but I have a few questions.
I'm still on stock 4.1.2. and used Marmite V5 Stock OTA zip.
After flashing the kernel I noticed that I had no extra options in the settings menu. I take it because I'm still at stock these options aren't available?? If I was to flash a custom ROM and the 'All Other Roms' Marmite zip I would have these options?
Another thing, after the factory reset I had to install a few things from the market. I also got an notification exclamation error which I had never had before, it said 'need google play services' and took me to the Play store to install it. I have never had to install this app before and I'm wondering what it is.
Thanks.

install NS tools then you will have the "extra options"

Do I need to flash that or can I get that off the market?
Tbh I'm not bothered about tinkering. I just want to know that leaving the stock marmite kernel as is will be fine for my phone?

[KERNEL] [JB 4.2/4.2.1] Stock kernel - CWM flashable

Hello all,
I made this over at the GNex forums for a stock GNex 4.2/4.2.1 kernel... here it is for the Nexus 7 for those that accidentally flashed a 4.1.2 kernel or just want to get back to stock.
Flash at your own risk, should work just fine though!
UPDATED: Kernel should work now! Sorry about the bad zip before!

Will it work on 4.1.2? I have AOKP on my device, would like to flash this, just need to check if it's safe...
Cheers

where were you couple of days ago when I was dealing with the issue - trying to flash stock kernel.....wish you posted this before.
I will save this just in case :silly:
thanks!!!

I flashed LeanKernel and then wanted to go back to stock kernel before flashing latest Faux Kernel.
So I have just flashed your kernel but "about tablet" is telling me I still have LeanKernel installed?

If you can overclock then you're still on lean kernel. Either way, I'd suggest a reflash.

It was definetely still on LeanKernel, I tried it twice.
Only issue could be that I was using an older version of TWRP that wasn't updated for 4.2, but it seemed to flash ok.
edit
Ok, tried it again now I have the updated TWRP and the same thing happens...i.e. nothing, it flashes in the normal way but changes nothing.

This is all wrong. The boot.img inside does not match the one from the N7 nakasi factory image and the updater-script is written for the Galaxy Nexus.
Code:
"of=/dev/block/platform/omap/omap_hsmmc.0/by-name/boot");
N7 certainly doesn't run OMAP. Flash at your own risk, indeed.
I urge you to take this down and make sure you know you've got it right before you put it up again. Only saving grace here is you were using the platform by-name method (which just plain won't work on the N7) instead of the actual mmc block names or you could have really messed up some peoples' devices.

My mistake. I thought it would just transfer over. I will fix the link... Didn't realize when I tested it I already had the stock kernel on there. Gimme a minute to fix it!
OK should be fixed and good to go! Again, my apologies!

Please try again... I have updated my zip and tested it by flashing a 4.1.2 kernel, having the device sit at the X for a few minutes without doing anything (to test a non-working kernel) then flashing my zip, and my N7 is back up and running again.
I am still learning about kernel stuff... sorry about any confusion!

Negative. This is the stock 4.2 kernel... I found the stock 4.1.2 kernel on XDA... Should be easy to find!

wasn't that hard to find out, but here you go: stock kernel

This is JOP40C kernel for 4.2 but will it work on JOP40D 4.2.1 stock ROM please ?

Can anyone confirm if the kernel listed (jop40c) is the actual kernel used in the stock 4.2.1 system? The build is jop40d, and the question seams to be getting overlooked. I cannot find the stock jop40d 4.2.1 kernel anywhere, and just do not have any interest at this time in flashing the factory image/re-rooting etc. Any help would be appreciated.

This.. I was about to post, my N7 (16g, wifi) is JOP40D as well, not 40C.
Thinking about trying out a custom kernel, but want the stock to fall back on, as it's super stable.

As it turns out, I built a "slightly rooted" JOP40D stock flash kit yesterday (mods to build.prop in boot.img, and su/SuperSU in system.img). I'm posting this reply from that.
I started with the Google JOP40D (grouper) distro to do that. I thought I was going to need to unpack the boot.img from the OP's .zip to do comparisons of the kernels (to answer your question) ... but it turns out that his boot.img has the same MD5 sig as the boot.img from Google's JOP40D... and the OP's updater-script merely flashes boot.img to the /boot partition.
That means one of two things: either the two successive Google releases (for grouper) had identical boot images (which implies identical kernels), or there is some mistake by the OP. (I don't have the 40C distro to check ... only picked up my N7 a few days ago.)
It should work in your specific case though, as you are on JOP40D.
In any event, flashing boot.img is way way more than just a kernel replacement. I haven't looked at it for a while, but I would suppose that Koush's kernel flasher is a much more appropriate technique for switching ONLY the kernel out from underneath an arbitrary ROM.
cheers

That's great info there. I'm searching for the simplicity of just flashing a kernel instead of pushing the entire boot image. Thanks for a step in clarifying this question

[Q] About rooting and custom kernel

Ok here is the thing i have few questions about rooting my device and flashing custom kernel.
1) I want to root my nexus 5 and yes i saw the tutorials its not my first time to root a device but its first time on n5 so if i root it and install custom recovery and keep stock rom and kernel will i be able to recive ota updates without any problems? Or if i just root it and keep the stock recovery will i be able to update?
2) And my second question will franco kernel work fine on stock rom? Because if my first question is not possible then i would flash franco kernel on my device too and later when an update for stock rom comes i would flas it manually of course if that is possible too?
Thanks for help.

No because you're rooted it won't accept the ota update due to modified software.
