{Q}Bootloader question do they work with all newer roms? - Captivate Q&A, Help & Troubleshooting

Ok here is the setup I'm running the new Cog with i'm assuming the new CWM it don't even go into 3e any more i've been waiting on the side line with the GB upgrade reading and trying to figure it all out.
I pretty sure i got the flash part worked out going to use Heimdall to do it because i only have access to a linux machine...
I get what the bootloaders are for are they backwards compatible say i flash them will they work even if i want to run cog some more?
When i start flashing diffrent rom's will they get changed back or will they only change if i flash them in heimdall?
Thanks any and all help will get thanks...

yes you can still run cog with the GB bootloaders. they should not be replaced by any rom flash...just make sure before you flash a froyo rom that in the updates folder it doesnt conatian a sbl.bin if it does dont flash it that is a froyo secondary bootloader and it will brick the phone if paired with a GB primary bootloader.
now after you flash those bootloaders and want a GB rom just flash a Gb kernel boot directly into recovery and flash the rom.

Thank you bro...

Bell SGS bricked or saveable?

Hi,
This is my first time experimenting with flashing custom roms. I was trying to flash a custom rom onto my perfectly working newly rooted sgs (using odin), but the first rom i tried has gotten my phone to boot loop and now I don't know what to do with it. I can get to the download screen just fine and recovery mode but don't knwo what to do. Please help, I really can't afford a new phone/ don't know if samsung will let me replace it now.
Oh, the rom was the XXJVK Gingerbread which is near the top of the forums right now, if that helps at all.
I really just need my phone to be usable, I didn't expect to mess it up. Thanks again to anyone with information.
I assume you were running jl2. The problem might be because of bootloader issue.
When you were flashing gingerbread did you use pit file and repartition?
I am not a pro but If you download JL2 and flash it, should be good to go. Try not to repartition and flash without using pit file.
I did use the .pit and repartition. I'm guessing this was a no no? I'll look for jl2 and try flashing that. Might you direct me to the right download?

I have no idea if it will work or not. Same thing happened to me also when I was trying to flash darkys rom and I was able to open the phone after I flashed with bells original rom. Give it a try. If its a boot loop I assume its a firmware problem. You should be able to fix it. The problem might be the repartirion and pit file. I am not sure about it. Hope this helps.
Just try flashing again with boot loader update ticked in odin. I'm pretty sure that repartition and pit do nothing to the bootloader. If that doesn't work I'll add more after I shower, I stink!

A bootloop = ****ed framework and/or /system/ (rom)
Flashing bootloaders will not fix the problem, they are not related at all. And if a bootloader flash fails your phone will actually be bricked.
Just flash a stock rom with odin. I recommend jl2 if you want to go official stock, js8 for fastest froyo stock or jvk for the latest leaked beta. Tick update bootloaders for jvk or jl2 flash because jvk requires jvk bootloaders and jl2 because it supposedly fixes corruption problems. Remember bootloaders are overwritten every time you flash them and us risky.

Thanks a million guys, I did flash the stock jl2 (no .pit or partition, nor bootloader update) and the phone booted. It fed me a gajillion force closes, but i managed to connect to kies and updated it that way, so now I have a perfetly working phone again. I'll probably experiment with a few more things now that I know how to fix this.
Again, Thanks guys!

[Q] How downgrade Galaxy S to froyo from gingerbread?

My i9000 is on i9000xxjvb stock rom. I flashed modified kernal to make it rooted and cwm enabled. I am unable to move appear from phone memory to internal SD. An error message appears " failed to move application, not enough memory."
To get rid of this, i tried Hamsterbread 1.1 custom rom, but problem not solved. I used every method from hard reset to wipe cache, data and more. But nothing happened.
Now I want to downgrade to froyo. I don't know how to do this? Please, tell the procedure in detail and step by step. I belong to India. There is no 2.2.1 version available for India. Can I go for other regions versions? or I should stick with i9000ddjp6 which is latest verison for India. Thanks
i havnt tried downgrading. but i think you could try flashin back using odin with bootlooder froyo.
i live in india but use european firmware an see no problem
^^ Im not sure about this. I think you can just flash a Froyo ROM via CWM. I am not sure about this. It always makes sense to search around before you do either. Good Luck!
If you flash speedmod (or whatever froyo kernel you choose) through odin, then simply install whatever rom through cwm via zip file. The downgraded froyo rom doesn't need bootloaders, the gingerbread ones are backwards compatible. Tried it myself and it worked without a hitch.
Just flash any stock firmware through ODIN with pit and repartitioned tick and you are good to go.
Makes sense to open eyes and read the post that tells you how .Or even use the search button .

just download a stock froyo firmware and flash with odin. there are tutorials all over the place
just flash froyo kernel using odin and then enter clockwordmod install zip

(Q) Continuum 4.1 & GB Bootloaders

Is it safe to flash continuum 4.1 (Froyo version) while i have the gingerbread bootloaders on my phone? I ask because I have recently learned that some roms will change the second bootloader while flashing (cognition) which is no bueno if I still have GB bootloaders.
Thanks
Should be. I know v4 is safe to do, I did it myself. I also know that Cezar doesn't like messing with bootloaders, so I font think he would add one to 4.1,IMO

I want to see the difference between continuum 4.1 and 5.5 (mainly battery life)
For the install I figure I will flash the Onix kernal though odin with reboot unchecked then boot into recovery and flash the 4.1 rom. I reckon this should be safe eh?

Both have totally different bootloaders....Dont try this method u will hard brick your phone...try flashing stock using various methods written on the OP of Continuum 5.5....Dont be lazy and flash to stock to go back to froyo....u will have less chances of bricking ur phone
Also Onix is froyo kernel...I am sure it wont be compatible with GB rom

I don't think you read my post correctly. GB bootloaders work fine on froyo roms and really, the easiest way to hard brick the phone is while odin is flashing the bootloaders.
BTW you can flash a 2.2 kernal with reboot unchecked, pull the battery and boot directly into recovery mode to flash the 2.2 rom without issue. Continuum 4.1 does a full wipe anyway.
Thanks for your opinion tho.

Cezar has a "safe"method to return to stock (jf6). It is jf6 tar, without bootloaders. It had its own thread in development, and its also available in the op of the 5.5 thread. If you follow the op, you should be ok.

question before i flash again.

well, i have had some issues flashing my phone to 2.3, and it is currently on continuum v5.5 working fine for a few versions. so i don't want to rush into anything and mess it up again, but i want to try another rom. im a little confused to what all i need to do to get the new phoenix rom on coming from a talon kernel.
thanks!
Just use ODIN ONE CLICK STOCK (http://forum.xda-developers.com/showthread.php?t=731989 and then place the rom of ur choice and flash it in CWM!! tell me if u need anything else
Odin back to stock and follow instructions in the OP for the Pheonix thread.
You need to verify that your current installed kernel is compatible with your new rom of choice.
If not:
1. Find one that is compatible, install it via odin without rebooting - then boot to recovery and install the zip file in cwm.
OR
2. Odin one click to stock and go from scratch.
If going from GB to GB rom then the important thing is the kernel compatibility or you will likely go into bootloop. Other than that wipe, reset and install.

GB bootloaders with root

What Odin/One click package should i download to get root with GB bootloaders with CWM and flash zip file roms only? So i can flash roms like Fasty III and others? Which one is suggested for great battery life? Experts please
First off you don't need root to flash a rom. as for bootloaders use either a leak 2.3.5 i897 rom with bootloader or just the bootloader package. They are stickied in Dev section.
Can you please send me a link im new at all this but im learning i have Odin 3 v 1.81 and Odin v 1.81 ATT GB bootloaders extracted. I just want to be able to use download mode jig and plug in USB and go.
I have UCK H3 one click is that good enough to get started? Could i flash a rom in rom manager like fasty III im looking for fast and grt battery life.
KH3 1 click should be good. Don't use Rom Manager. Here you can find everything you will need. Just flash KH3 or any other GB leak, let it boot up normally, flash (with ODIN or SGS kernel flasher(app)) the boog's kernel that has CWM, let it boot up normally. Boot up in recovery and flash the rom.
Yea ive seen this which one should i pick and with or w/o bootloaders. 2.3 or 2.4.5 not sure? Just want the best one for speed and battery life and i like launcher pro.
I don't use launcher pro so can't say. But IMO KH3 or KJ3 would be my best (I still use KH3 modem). You need bootloaders so you can flash one with bootloaders.

SGS kernel flasher requires root. Which rooting involves a kernel swap with Odin anyway, so for this purpose its pretty useless.
I just flashed UCK H3 and while in process i checked flash bootloaders now im soft bricked. Will the download mode jig help? I have one i dont know what to do. It doesnt work. What can i do am i screwed? I have the soft brick symbols on my phone now.
Reboot pc, swap usb Ports (make sure its one on the back of the PC), right click Odin and ruin as admin, put .tar in pda slot, Pull battery, replace, use jig, ignore screen that appears, connect to PC if Odin recognizes it hit start.
Grt thanks ok i got the fish now what do i reboot or what and add kernel next? I still have Odin opened and USB plugged in
Disconnect, close Odin. Pull battery, replace, use jig, flash boog's kernel the same edu you flashed the fugu kernel.
Im getting a screen that looks like a TV screen all lines what the heck is that? Its boots to ATT logo then TV screen all colors and lines. I did the kernel it passed but not sure whats going on now. It keeps rebooting ATT screen and TV looking screen
... That sounds like you didn't flash correct bootloaders. Correct me if Im wrong. On a side note ya Studa I had a brain fart on SGS kernel flasher.
I can still get in download mod with jig. Cant i try a diffrent package in Odin?
Did you use KH3 with bootloaders?
Not sure what to do im trying the AIO toolbar and im enabled for root phone but seems like nothing is happeneing im still in download mode
that is froyo boots on a gingerbread ROM.
op flash this package
That will flash the gingerbread bootloaders which will get rid of those lines and make it possible to boot into recovery.
DO NOT USE AIO TOOLBOX AFTER THIS PACKAGE IT WILL BRICK YOUR PHONE. might as well just delete that for safe measure.
Ok i was in recovery in rebooted phone now im at ATT screen logo no lines now. What do i do now is there a rom to flash or am i even rooted? Can i go into download mode and flash a kernel
Im staying at recovery till i hear back from someone lol. Where do i go from here?
