Questions about installing ROMs and reverting to stock

I've recently rooted/installed CWM on my Sprint SGT, and I'd like to try out spacemoose's HC build. I've never flashed custom ROMs before, so I've been reading around to try and make sure I understand everything and I don't render my SGT useless.
Will I just download the ROM through her thread and choose "Install .zip from sdcard" in CWM recovery?
Assuming that's correct and that all goes well, how would I revert to stock? Would I do it via a similar process with a stock .zip file? If so, where can I get this file?
Also, it appears that there are only a couple CDMA ROMs out there. It seems that GSM users can use a ROM regardless of TMO/ATT affiliation. Is that the case with CDMA?
Thanks for the help!

The HC of spacemoose is still in the early stages of development-even alpha stage. Definitely not for beginners to try out.

It seems there are two CDMA Roms available. Can to recommend one to get familiar with the process?

I think you are on gingerbread 2.3.3 firmware. NO YOU CANNOT USE recovery to install/flash a new version of the firmware as HC is android 3.0. The install from zip is only used for the same firmware version.

I'm on Froyo 2.2

I installed SpaceMoose's Alpha 2 and then upgraded to Alpha 2.5. If you install a launcher (ADW or VTL) it greatly improves the usability of the Tab.
I will say this, if you need to use it for work or as your only device then I would hold off. I am extremely happy with Alpha 2.5, but there are a few quirks.
Data (3G) does not work yet
Occasionally it will freeze up and require a reboot
Some apps aren't playing nice (personally I haven't been able to get Google Music to sync)
With that said, if you still want to go do it, then here is how I did it on my Verizon Tab (should be similar since they are both CDMA)
Starting from stock, unrooted:
Installed the over the air update EC02 (or you can download it on XDA)
Rooted using SuperOneClickRoot
Installed the VooDoo kernel to get CWM 2.5 (apparently CWM 3.0 has some issues)
Put SpaceMoose's ZIP file on my SD Card
Booted into CWM
Install Zip from SD Card
Choose ZIP
Install
VIOLA!
Not sure on the process to get Sprint Tab back to stock. I used Heimdall and the instructions found on XDA and DroidForums. I did see this thread for Sprint (http://forum.xda-developers.com/showthread.php?t=1009926).
Hope that helps.

[Q] GB Bootloaders

I am running Cog 5B2. It has the captivate GB bootloaders. If i want to change to a i9000 GB rom say Apex do I need to change bootloaders or will the GB captivate ones work?

No you do not need to change bootloaders to go to any other gb rom. Plus I've read on here that the gb bootloaders are backwards compatible with froyo/eclair though I have not confirmed that yet myself.

So there really is no need to ever flash bootloaders again.

I wouldn't say never. But it is good to avoid flashing bootloaders if possible, if something goes wrong flashing bootloaders can result in an actual bricked phone.
On the other hand just flashing roms, kernels and modems sans bootloaders the worst you can likely do is get into soft brick situation or a bootloop which can be easily fixed.

Yup I flashed Serindipty7 right on top of cog 5.2 and then Mosaic V right on top of that no issues to report just make sure you wipe data factory reset before. I haven't flashed anything that has the talon kernel, but still no need to flash bootloaders

Keep it mind GB bootloaders are not backwards compatible with all of them. I know that CM7 does not work with GB bootloaders.

I prefer the I9000 gb bootloaders. They both work the same but The captivate ones have the same button combos which I've always thought were really stupid. The I9k's combos are just more intuitive and simplistic the way they should have always been if you ask me.
Vol up + power = recovery
Vol down + power = download
Nice
Clean
Simple

Well turns out going from Cog5b2 to OBSSESSION puts you in a bootloop. Reflashing Cog I guess for now.

Try flashing to stick KF1 before flashing a new rom (there is a 1 click without bootloaders to minimize risk)

I haven't still figured out a reliable way to flash back to Stock Froyo on my 2 captivates which ended up being bricked. I was on Cezar's 897 GB bootloaders. Tried flashing back to Froyo KB1 from here but it failed using Odin3 1.3. I got a new phone, which now has stock KB2. Does anyone know how to flash stock Froyo reliably ?

I read someone have similar issue and I was also on cog5b2 and followed their instructions (which I'm going to paraphrase now) and worked perfectly. I'm now running Mosaic V with the KF1/i897 boot loaders...
OP on Mosaic V has link for xcal's 1.2 i9000 kernel.tar download that. Start at step 5 on that OP, use Odin 1.7 (linked as 'Files you will need' in the MV OP) to flash xcal's kernel, make sure to not auto reboot from Odin and when it's done flashing kernel, do a battery pull and then go to recovery mode, factory reset and then flash Obsession.

Yes, but aren't both of them methods to go back to Eclair and not Froyo ? My earlier Cappy got bricked bcoz I tried stocking back to Eclair, when it came with Froyo.

My question is how do you flash custom rom while on kf1 boots? Running cog 5 beta 2 with cwm4. Can I flash roms like I did before via cwm, even though I'm on cwm4, or should I flash a kernel with cwm 2 or cwm3 first, than flash rom thru that?. This question is for both froyo and GB/i9000 roms

Well most roms have a Kernel that they recommend. Best I can figure if you want to flash a froyo rom go back down to stock eclair with one click (don't flash bootloaders) and flash rom of your choice. For GB just flash stock KF1 and flash gb rom? That's just me guessing though.

Oneclick eclair contains bootloaders.
To simplify my question, are rom flashes compatible with cwm4, or do I need cwm2/or 3 to flash roms, whether froyo/GB?

JF6 is eclair is it not? If it is here is a JF6 odin with out bootloaders. If Jf6 is Froyo well my mistake. Still 2.2 stock would still work i think. Point is cmw version wont matter if you go back to stock and flash from there, and its usually a better idea to flash to stock anyways.

Kernel flashing problem.

Okay, just got a captivate. I rooted it no problem. I couldn't flash cwm to flash cm7 without a custom kernel that has cwm on it. So I got odin3 1.7 got my phone into download mode and flashed first the cornkernel, once the phone booted up it had a crazy screen with all kinds of colors. Okay, wrong kernel, then I did boog Kernel, same thing. Can someone point me to a kernel for the stock 2.2 rom that has cwm so I can get cm7? Sorry to post, but there is so much info and I've already spent hours trying to find it.

Found one here. So, anyone coming from stock and you want CWM, use the kernel. http://forum.xda-developers.com/showthread.php?t=893880 Boy I tell you, took forever to find.

You need GB bootloaders to use a GB kernel I believe.

That is correct. Corn is based on the KK4 source (Gingerbread). You must have the gingerbread bootloaders to use Corn. You (OP) might want to double check the directions for CM7 before you attempt any more flashing. Reading the instructions first can help prevent you from turning your device into an expensive paperweight. The instructions include how to go from 2.2 to CM7. They are HERE

Once I got the right kernel I was able to flash the newest nightly with no trouble. I'll have to start with the wikki next time, thanks for the link. It just turned into a mess going through these forums and Google, because this devices has been out a while and there were so many ways to do things, and a lot of them no longer supported.

I always like to include a link rather than just say go search. I've tried searching for certain keywords before and you get just about every thread in the dev section returned.
I found that issue moving to a ROM the other night. The developer suggested flashing to KJ3 stock then flashing Boog to get CWM. I figured I would just flash KK4 stock, then flash Corn, get CWM with that, and then flash the ROM (which included corn anyway). There are so many ways to do most things on the Captivate these days.

[Q] Samsung fixed my captivate but now...

Samsung fixed my captivate after the mini USB port broke and I intentionally bricked it with an Odin flash pull because they would have known it was modded/custom rommed. So they fixed it and sent it back and everything works(Thanks Samsung!) but the problem is that they flashed the new 2.3 update which is sooo slow/laggy and featureless compared to Cyanogenmod7 181 nightly that I used to have on my phone. What I want to ask is if I can Odin-one-click back to JF6 stock 2.1 from 2.3(ATT GB bootloaders I think?) and then go about rooting and such from there to get Cyanogenmod back onto my phone.
Thanks,
kind3rgarten.

Yes you can....but that's more work than it's worth.
Just flash a custom kernel with Odin...boot into recovery with button combos and flash whatever ROM you want. easy as pie

Thank you for the answer, but I am more familiar with flashing the rom this way. Are you sure I could do it this way? There wouldn't be a problem with the bootloaders or anything?
this way == odin1click back to JF6 then root then CWM then flash CM7 and gapps
also, would there be any difference in performance/battery life or anything if I were to go your route?

If you used it before it's still ok, just like i said that's a much longer process than what's needed, and by flashing bootloaders when you don't need you're taking an unnecessary brick risk to downgrade to obsolete bootloaders. Gingerbread boots are backward compatible, so they will work with ANYTHING. so why go back and then if you wanna use a tw gingerbread ROM you'd have to update to the new ones anyway.
your process:
Flash to 2.1
Root
Get cwm
Flash ROM
And that includes bootloaders so if it disconnects you could brick.
best way
Flash kernel to get cwm
Flash ROM
2 steps and no bootloaders so at the very very worst case scenario, you get stuck in a bootloop which is much easier to fix than a hard brick.
That being said you're way will work, so whatever floats your boat...

Plus, if you ever decide to try a Gingerbread ROM, you'll have to reflash the bootloaders again anyway, again risking a brick.
If you really want to go back to 2.1, I would still use a bootloader free package.

So would I just flash a kernel that already has root/CWM? Then flash CM7/gapps on top of that?
I would post a link, but I don't post here too often.

Yeah, I see what you mean, thanks. Can bootloaders effect battery life, because I remember that I didn't get the best battery life in CM7?

Cm7 is aosp based it doesn't have all the closed source hardware drivers of touch wiz, so the battery life will be worse.
As for the kernel, any will work. It's not a kernel you're going to be running it's just a transitory kernel used only for it's recovery. Any ROM you flash will include a compatible kernel and be rooted.
Hold on I'll find you a kk4 kernel so it won't bootloop even though you don't need it to boot all the way anyway... Brb
Edit: kk4 corn kernel grab the Odin flashable version of corse.

Correct. If you remember to put CM7 and GAPPS on the SD card before you flash it, you won't even have to boot it. Just flash it, three finger salute into recovery, and flash cm7.

Wow, I really expected someone to just call me a noob or tell me to read the FAQ or something. Thanks a lot, both of you.
I downloaded the corn kernel, but I've never really flashed a kernel through odin before, always just the method I had stated, does it go in PDA?

You got it, just leave the others blank. You shouldn't have to play with the check boxes.

So let me get this straight...

I recently upgraded my Note to official ICS (OTA) and I'm not liking it AT ALL! Now I really want to get far away from this update as possible and I'd like to switch to a CM9 nightly Rom. I've that now that I have upgraded to the official ICS Rom, I run the risk of super bricking my device. So now I ask you to help me make sure the following is correct so that I may move on from this wretched update:
DO NOT perform wipes if you are on original Samsung ICS
DO NOT perform wipes if you are on a original Samsung kernel??
Flash back to original Gingerbread Rom using odin BEFORE flashing to CM9
Flash to different kernel??
I've flashed millions of Roms but this one is scary and I just want to make sure haven't missed anything... Have I?
Thanks for you help!!
John J

Just flash a stock directly rootable GB rom, root and put CM9 on it. Then do a factory reset and you're good to go. Went that way few times already.

So is the super-brick BUG on the official ICS OTA?? OMG
And yeah go back to gingerbrear via odin, get root then flash any CM9 tru CWM no problems...

I'd like to do something similar to what the OP wants to do however I have rooted and installed CWM on an official/stock ICS rom. So if I wanted to flash back to a stock gingerbread rom would I need to remove CWM and/or un-root?

There is no need to unroot first. You can flash stock GB rom directly via Odin.

I've now flashed to GB but before I move on to a CM9 nightly, do you recommend I flash the CM9 kernel as well? Seems like it is not a prerequisite but I would like to make sure. Thanks.
John J

afaik, when flashing a CM9 Nightly, the eligible kernel is built in, so no need to flash anything but the ROM.
i'm on one of imilkas first CM9 port and it says [email protected] #1 under Kernel version in settings.

Yes. The correct kernel is included in the nightly.
