[Q]Flash Back to stock 2.3.3 without bootloader? is it possible?

Be running currently the new bootloader
if anyone can help please I have done these actions and needhelp:
1 .- I did flash rom GB-12, now own the new bootloaders. (I did not like the rom GB-12, personal opinion)
2 .- I returned to stock (eclair) maintaining the new bootloaders(Gingerbread boot loader) with the stock rom by icezar1
icezar1ROM stock without boot loaders http://forum.xda-developers.com/showthread.php?t=995143
thus verified that the new boot loaders are compatible with earlier versions (2.1 and 2.2)
3 .- continumv5.2 flash ROM (where I am right now)
My questions are:
as I can get stock of gingerbread without having to flash the newboot loader?.
I want to avoid being reflash bootloaders
I for example go to the rom apex6.1, [ROM][2.3.3] Perception II Beta 2

do not need back to stock 2.3.3 gingerbread? http://forum.xda-developers.com/showthread.php?t=1045734
sorry so many questions, I want to be sure

DO NOT FLASH COGNITION!!! It has a froyo sbl.bin and on gingerbread bootloaders it will brick your phone. No question about it. Dead. A corpse. A cadaver. No life in it.
Otherwise you are good, I flashed from firefly to continuum 5 rc3, to perception 2, to mosaic (biased personal favorite). No reason to go to stock.

I also has a Q. So now that I have 2.3 bootloaders installed. Should I ever have to flash bootloaders again? Or at least till 2.4. Can I just del sbl.bin on what I flash?

The only thing you have to fear is Cognition as he has the froyo sbl.bin for the 3 button fix.
Other than that, you should never have to reflash your bootloaders (beside going stock for waranty).

Thanks for the info

Can someone clarify something for me please?
I flash Continuum 5 and also gingerbread bootloaders usig ODIN. I followed instruction from MobileTechVideos.
My question is this...if I wanted to try another ROM based on Froyo how do I do this? Would I need to flash back Froyo bootloaders?
And how do I go about just flashing another gingerbread based ROM?

Well you just make shore no sbf.bin file in rom by unzipping it and checking...(i don't know of any roms that still have those in then now, even cognition doesn't anymore.)... To flash gingerbread rom it is same as with froyo, I use cwm. I've heard serinity 7 is really great. So just flash as usual, but with froyo roms just be careful and check first..... BTW trance is way better than techno, just saying

Just make sure the ROMs you're going to flash will not either flash your Primary Bootloaders or Secondary Bootloaders. Then, you're safe.
Primary Bootloader(GB) + Secondary Bootloader(GB) = Alive.
Primary Bootloader(Froyo) + Secondary Bootloader(Froyo) = Alive.
Primary Bootloader(Froyo) + Secondary Bootloader(GB) = Dead.
Primary Bootloader(GB) + Secondary Bootloader(Froyo) = Dead.

You can use the eclair one-click to get back to stock, DO NOT USE THE ONE WITH THE THREE BUTTON FIX!
Also you can just flash a froyo rom and kernal without reboot in CWM.

[Q] 2.2>2.3.3>2.2 Can I go back to 2.3.3 again?

So I was on a froyo rom and flashed to a gb. All was working well for a week. I ran into an issue and flashed (Odin3 one click 1.7) back to my previous froyo set=up. The gb rom I was using has been fixed and I want to go back to it again. Is it ok just to cwm the gb rom or do I need to go through the whole process of flashing bootloaders etc...

odin one click flashes eclair/froyo bootloaders. yes you will have to flash gingerbread bootloaders again. don't be afraid, how many times have you used odin one click? that has the exact same risk involved when flashing to gingerbread. repeat flashing gingerbread bootloaders is the exact same risk as odin one click.

Hmmm interesting, I thought you couldn't do it ONLY if you used full Odin.

For future reference, you can go back to froyo/eclair roms and still use the gb bootloaders. They are backward compatible. If you want to flash jf6 just to start from stock, cezar has a safer method for Odin. It flashes JF6 rom, but not the bootloaders. You can find it in Development, it has its own thread and he's also put it in the op for Continuum v5.
There is one draw back. You can't flash Cognition or you'll brick your phone. Cog uses a secondary bootloader.

[Q] Odin one-click softbricks my phone

I'm having a bit of trouble with Odin one-click. Last night I decided to upgrade from Perception 10.4 (Froyo based) to Perception 2b3 (Gingerbread based). I plugged it in, put it into download mode, and activated Odin. It ran just fine, but at the end, my phone rebooted into a boot loop. I ended up putting together a jig to get it back into download mode, and tried again. Same thing happened. I eventually ended up using a Froyo Odin to qwerty least get it working again. Does anyone have any ideas as to why Gingerbread Odin soft bricks my phone, and what I should do to fix it? Let me know if you need any more details. Thanks in advance.

I know this would do better in the odin thread, but I don't have enough posts to post there, mending the fact that I've been lurking around for close to a year

Guess I'll just keep posting here until a) someone responds or b) I have enough posts to ask in the proper thread

I'd ready like to be able to get my cappy running Gingerbread tonight. Anyone have any ideas?

What one click are you taking about? Is it this one?
http://forum.xda-developers.com/showthread.php?t=731989
If it is, this will take you to stock eclair. Not sure what ur talking about with one click froyo. There is a one click GB from Design Gears in the development section. It flashes the newest release of GB stock. If you can get into dl mode you can flash either of the one click odins, but read about both before you do. Bootloaders are involved, and if you don't know about them they can be trouble. Read in development section.
This is a link to one click for GB stock. CONTAINS BOOTLOADERS.

Sorry, for some reason can't get that second link to work properly. Doing this from my phone. Just type in the url. If you decide to flash this GB oneclick, you'll be on the kf1 "official" release. Check dev section and you can flash beta cognition if you want. People are having great results with this rom, including myself. Good luck.
Sent from my SAMSUNG-SGH-I897 using XDA App

I recommend flashing the KF1 odin one-click. I just flashed that one, and it worked like a champ. Its in the Continuum v6 thread at http://forum.xda-developers.com/showthread.php?t=1136128. If you read the instructions it will work flawlessly. The only odin problems I've ran into have been user induced.

Okay, I'll try out that KF1. All I really need it for is to get the bootloaders so I can install other 2.3 roms. Will this work for that?
The Froyo Odin I was tackling about was just an older version, I think.
Edit: Why is it so much more difficult to go from 2.2 to 2.3 than it was going from 2.1 to 2.2? Upgrading to 2.2, I just had to use CWM to flash the new rom onto the phone.

Okay, I was trying to follow the instructions in the Continuum thread, and it looks like I am supposed to go back to Eclair before flashing Continuum. I was using this one-click Odin, and it was causing my phone to softbrick. No idea why. Will I be able to use that KF1 Odin to get to Gingerbread, then flash other GB based roms?
And by the trouble caused by bootloaders, you just mean how it will hardbrick if it loses connection in the middle of flashing, right? Or is there more. I've been switching out roms on phones for a while now, but it hasn't been this complex before...

If you mix bootloaders, you will hard brick ur phone. 2.1/2.2 roms have the same bootloaders. GB boots are different. That's why there is more involved to flash GB roms. Basically all the GB roms are I9000 based roms. The kf1 is an i897 based stock rom. If you flash kf1 stock rom, you will lose cwm. You can try cog beta 2 rom if you would like. After following steps to flash GB bootloaders with link mentioned above, check dev section. There are currently 2 kf1 custom roms. I use the cog beta 2, and it works great. people have mentioned that they have flashed i9000 roms over kf1, but I personally haven't, cuz so far cog beta is working great and the call quality is outstanding compared to any of the i9000 roms. Read read read read, before taking any steps. You don't want to ruin it phone! If you want to flash i9000 based GB, read this:
http://forum.xda-developers.com/showthread.php?t=1045734
Btw, what build is ur phone? (4 digit number under battery). Some builds, especially 1010 have trouble with oneclick.
Sent from my SAMSUNG-SGH-I897 using XDA App

So it sounds like what I need to do is use that KF1 Odin, then I can flash other roms over that? How can I tell which custom roms are KF1? Is Perception KF1 based? What would you recommend I read to make sure I'm doing it right? Are there specific threads that are especially helpful for this? Thanks for all of the help, I'd really like to learn how to do this.

It'll say in the title. Liked I said, currently there are only two kf1 based roms. Cog beta and another one that I can't remember the name of. If it says something in the title besides kf1/or i897, it's for i9000. Ex/ jvh, jvo, jvp are all i9000 based.
Sent from my SAMSUNG-SGH-I897 using XDA App

What do I need to do if I want to use a non-KF1 based GB rom? I've been very happy with Perception, and I'd like to keep using it.

If you want to flash GB stock that is based off of I9000 read and follow this, step by step:
http://forum.xda-developers.com/showthread.php?t=1045734
After you do this you can flash GB roms via cwm.
If you want to flash GB with kf1, you can, and people have been running I9000 based custom roms on the same bootloaders. JUST MAKE SURE YOU CHECK ANY ROM YOU'RE FLASHING TO SEE IF IT INCLUDES BOOTLOADERS. I personally haven't run any I9000 roms after flashing kf1, but I believe if you want to do this, (NOT POSITIVE ABOUT THIS, SO YOU MIGHT WANT TO RESEARCH THIS FIRST) you would have to flash an appropriate I9000 kernel using odin (not oneclick, but the full version). Put the kernel in the PDA slot, uncheck repartition, and auto reboot and flash. That way you will get cwm 2 or3 back which will enable you to flash the rom you want. (Remember, with stock KF1 you lose cwm). After kernel flashes, boot ONLY into recovery, and flash rom that you put on your SD card before doing any of this, and flash via cwm. AGAIN, NOT POSITIVE THIS IS WHAT YOU DO, SO RESEARCH.

That makes a lot more sense than the instructions I was trying to follow. I'll try that in a bit.

It worked! Thanks for all of your help

What did you end up doing? GB I9000 stock, or kf1 then flash I9000 custom rom over it?
Sent from my SAMSUNG-SGH-I897 using XDA App

I used the I9000 GB stock rom from that link you posted, then flashed a custom rom over it. I ended up using Perception 2 beta.

Glad it worked for you.

Going from i9000 to Captivate GB ROM? Bootloaders?

I'm planning on going from JVS to KH3 or KI2 but really don't feel like ODIN'ing back to stock. I know issues could arise if I just flash the i897 Rom over JVS due to bootloaders.
Any way to do this and get the Captivate GB bootloader without wiping with ODIN?

The only confirmed issue I've seen is that the I897 GB Bootloaders break the I9000 Music player. You should be fine just flashing whatever ROM with your current Bootloaders just do the typical clearings/wipes. Might have issues with the music player but that's easily fixed.

I did the same thing you're hoping to do, but all I did was ODIN the I897 BLs. No back to stock, nothing, just the BLs. I did it with the Pinnacle or Apex flasher package (can't remember which one right now). Worked like a charm.

This is Just the I897 GB bootloaders

Fix you flash the BL prior to the new ROM or after?
Thanks for the replies!
I don't think my phone gets along with JVS so well...

Either way is fine, before or after.

Agree with studacris—order doesn't matter. My experience was flashing the I897 BLs while still on Apex, then waited for the Pinnacle 1.3 update and flashed the ROM.

[Q] General Bootloader and Kernel Questions

Hello all,
I have a few general questions that I would really like some help with:
1.) I understand some bootloaders are not compatible with some ROMs. How do you know which bootloader you are running? How do you change your bootloader, must you use ODIN?
2.) How does the kernel come into all this, are some kernels not compatible with certain ROMs and bootloaders? When you flash a new ROM, does it sometimes come with a new kernel?
The main reason I am curious about this, is because I wish to flash the new Cyanogenmod 7.1 and want to be sure I am successful and do not brick my captivate. I am currently running Serendipity VII Build 2 and want to be as safe as possible when flashing Cyanogenmod 7.1.
Would the safest way be to flash to stock first using the following Odin one click method: http://forum.xda-developers.com/showthread.php?t=731989
Then from there, follow the instructions normally?
All help is greatly appreciated.

There are basically 2 types of bootloaders, Eclair/froyo and Gingerbread bootloaders. GB bootloaders are compatible with preatty much everything (not counting cm7 or MIUI).
Kernels are specific with a type of rom, example Boogs KH3 kernel worked with any rom that was based on KH3 (2.3.4). Some are tweaked specifically for a rom.
On CM7 and MIUI from what I can make out you can run it on either eclair/froyo bootloaders or GB bootloaders but some kernels are specific for bootloaders.

If you are on Serendipity then I am sure you used ODIN to flash i9000 boatloader (BL).
As the above person said there are eclair/froyo BL and GB BL....in GB BL we have captivate BLs and i9000 BLs. earlier GB roms used i9000 BL...then Samsung leaked captivate specific roms...so we have captivate BLs now..
All the one click Odins are used to flash captivate specific BL...
To go to CM7, many people flash it over GB bootloader and have no problem....but the safest way is to odin back to eclair/froyo stock...then go from there.....

Then I will simply flash CM&.1 on top of that.
I will report back to let everyone know how it goes.

did your phone come with froyo on it/what is the build number of your phone? its a 4 digit number on a sticker under the battery, for example mine is 1010, meaning oct. 2010. many phones built later than this, and/or came from the factory tend to bootloop from jf6 (the firmware containedin that one click) and have also been known to lose button combos for recovery/download mode which would need both if you were bootlooping and for cm7.
if you have a later build phone it would be better to flash a leaked gingerbread firmware with bootloaders included and then flash a custom kernel with cwm included so that you can then flash cm7 from there.

I purchased my phone at the end of August in 2010. The only 4 digit number I can see reads " 0168", it is the largest number located behind where the battery is held. And yes, I have lost my three button combo for recovery/download mode. It stopped working, and I bet it was because I used that one click method you mentioned.

You can use the bootloaders in the first link. At the time of that thread's opening, cm7 didn't support GB bootloaders. But, if your not sure how your phone will work with a1 click, I would recommend using the ones linked in my sig.
As for how to flash those roms, there are directions in the first post of their respective for flashing.
You can use a stock ROM everyday, most just prefer not to.

No one said you cannot use stock leaked rom as dialy driver, i actually used KH3 for some times and it was very good.
You should flash the kernel according to the rom you have flashed. For example, For KH3, there is a Boog's KH3 kernel with CWM. For all leaked stock rom, there is one click Odins and compatible kernels with CWM injected.
To go to CM7.1, u shud be on stock (Eclair/Froyo or GB) and should have CWM....

I need help too please. I have a Cappy that was originally on eclair 2.1 rooted. froyo 2.2 Kies mini update and rooted but didn't like it's battery use and slow action. I reflashed an Odin 1 click stock 2.1 back, rooted and then did a Gingerbread 2.3.5 I897UCKJ3_withBL_ Odin 1 click flash and am liking that quite a bit more. The only trouble I am having is rooting 2.3.5. I want to do the fugu kernal swap method with Odin3 zimage-root.tar then flash boog_KJ3_kernel3.tar. I can get into DL mode and hit the start button ok.
Here is the question I have. Where in Odin3 v1.83 do you load the kernal path? PIT,BOOTLOADER, PDA, PHONE or CSC. I can't seem to find a comprehensive Odin3 tutorial on my own and I don't want to flash the kernels to the wrong place. I don't think the first 3 options are right based on their names or info I have found. Can't use CWM till I get rooted so Odin or possibly Hiemdall are my only choices. I have Odin3.
HELP and TYIA

Kernels go in pda

When flashing a single file, unless its a modem or csc file, it will usually go into the pda slot. Modems go into the phone slot. Csc file is a no brainer. I've never saw anything that uses the bootloader slot on a captivate. Pit slot must have a pit file AND repartition must be checked. If you are flashing a kernel to get cwm just to flash a custom ROM, kernel goes into pda slot. If you want to user Odin to flash a modem, it goes into the phone slot. All files flashed in Odin must be a tar or tar.md5 file. Don't change the name of a tar.md5, it can cause a md5 check sum error.
There you go, cliff notes for Odin.
Edit
If I missed something or messed up something, please correct me.

When ur phone boots up and u see the i9000 bootsplash, then u have i9000 Gingerbread bootloaders (we didn't have eclair/froyo i9000 Bls). Also, button combo to get into recovery or download mode is different with the i9000 gb bootloaders.
And if u try and flash an i897 gingerbread rom (and don't see the i9000) but u have a "pixelated" screen, then u have i897 eclair/froyo bootloaders. If ur flash to a gingerbread rom is successful and u see the i897 (att world phone) bootsplash, then u have i897 Gingerbread bootloaders.
