Ok, just for clarification.
Downgrading from a custom 2.2 ROM to 2.1 requires a 2.1 kernel.
Meaning I should first flash a 2.1 ROM/Kernel combo, before restoring my stock ROM backup of 2.1.
But, what if you use ODIN. Can you go from 2.2 Rom/kernel, and put your phone straight to stock 2.1, using the pit and tar file for ODIN found in this forum? Will using ODIN to go back to stock conditions install the proper 2.1 kernel?
THen what about my ROM backup that I made, do I even need to ever install that back, or will the ODIN pit and tar files on this forum put me back to stock?
confusing question, I know!
Yes odin brings you back to stock completely just like it was out of the box I just go through and install everything some people make backups on they're computer of the apps they had
Still flashing , thanks to odin & tw
I am on Bionix 1.2.1 i have voodoo disabled. And i was thinking if i could Odin to the original stock 2.1 rom (JFD) without any issues.
I ask this only because i keep reading about Eugene's froyo that does not brick. Apparently it is supposed to be used in a certain scenario or the phone will brick while trying to Odin back to stock.
I am curious as to what situation is Eugene's Froyo used. And if this is indeed the situation that is required.
You only need it if your go back to stock and your phone goes to the galaxy s logo and dissapears
Like flashing an eclair kernel with voodoo
You can use it but it will wipe your entire sd

The Froyo that does not brick is a go between custom 2.2 rom and stock. There are times when trying to go directly back to stock causes the flash to fail and it boot loops or just hangs stuck on opening screen or just goes black. In those cases the Froyo that does not brick resets enough of the data the the stock flash recognizes correctly where to place the data. That is why it is wise to have that rom as well
OK, I admit it. I'm a coward. I am a complete scaredy cat when it comes to changing my bootloader, or to even using Odin. I like the safety and simplicity of recovery, and as such a spineless person, I have a few questions about some general workarounds that may or may not work.
While each ROM has its own instructions on how to install or uninstall from this or that, or how to move from Froyo to Gingerbread to CM7/MIUI to Eclair to Gingerbread to Froyo and back again with or without Froyo or Gingerbread bootloaders, with or without Voodoo enabled, with or without a complete wipe, with or without your IMEI intact, with or without an Odin to stock, and back and forth and back and forth.
I have a question which, hopefully, will apply to the majority of those transitions. I am currently using a 2.2.1 Froyo ROM with a Froyo bootloader and Froyo kernel. I would like to ask, nay, CONFIRM a scenario where I move safely to a Gingerbread or CM7/MIUI ROM built for the Samsung Vibrant without changing my bootloader, and without having to use Odin, either to switch to OR switch back from Gingerbread or CM7/MIUI.
Now, I've read a LOT about this subject. The problem with reading as much as I have is that you end up with conflicting data. Even if it's only 1 post that says you can do it an easy way and 100 others that say it's wrong, if the 1 post is saying what you want to hear, it's hard to dismiss, and so I will ask the question.
Is it possible to move to and from the many various ROMs and Kernels using only an intelligent use of Titanium Backup, ROM Manager, and a Kernel Flasher?
For instance, I make a full backup of my Froyo rom, and over to Gingerbread. I change my mind, and to return to Froyo without using Odin or Gingerbread bootloaders, I use a kernel flasher to flash a Froyo kernel (probably Bali), which supposedly puts me in soft boot but allows me access to recovery where I can go back to my Froyo backup. I'm also assuming this would work with a change from Froyo to CM7, or from Gingerbread to CM7.
Is this possible? Assuming I do a complete Data/Cache wipe and Fix Permissions as well as a Titanium Backup of 3rd party apps and a ROM Manager recovery backup of the ROM in-between every step.
This would work on any touchwiz based gingerbread rom. If you flash CM7 or anything CM7 based (trigger redux or miui) you have to use Odin to get back. If you flash any of the touchwiz gingerbread roms you will not be able to see the recovery without flashing the bootloaders with odin.
Does CM7 modify the bootloader? Is that why you have to use Odin to return to Froyo?
I appreciate the help, but I'm also just curious
I *could* be wrong but I think its because that CM7 uses a newer version of clockwork that our foryo roms don't support. It doesn't modify the bootloader.
Update: this is what I'm talking about
ok well for any of the gingerbread roms you really "need" to flash a gingerbread bootloader using odin, now while it isn't mandatory, for daily use clockwork access etc you will want to do it. I don't recommend it,
Now i'm comfortable with Odin and confident in myself and my phones hardware to not brick my device. I still won't flash a bootloader, cause if i forget to odin froyo bootloader before flashing a froyo rom, hardbrick.
now CM7/Trigger/Miui is different yes you need to use Odin to go back to stock/froyo should you decide you don't like them, there is less possibility of screwing up because all you do in odin is
Pit = 512.pit
PDA = T959UVJFD.tar
uncheck Auto Reboot (If odin fails just reflash again no need to reload etc.)
Check the following boxes.
Repartition
reset time
thats it.
installation of CM7 based roms is equally easy.
use the attached update.zip to flash Clockwork Recovery 3x (orange)
power off (pull battery) 3 button enter recovery
Factory Reset/Wipe Data
goto mounts menu and format system
Flash CM7 based rom (cm7, trigger, or miui)
Fix permissions
now while you do have to use odin to revert atleast your not messing with bootloaders, which gives you a certain degree of security in knowing that theres very little chance you will hurt your phone in any way.
hope i've simplified some things for you

Correct, and to add on it, CM7 is AOSP. You can compare it more to the Nexus S atleast in filesystem structure
CM7 CWR (Orange/Blue 3X/4X respectively)
Vibrant 2.1/2.2 CWR (Green/Red)
as far as i know you can't flash a previous version of clockwork recovery, then again i honestly have never tried. It may be possible?

No CM7 actually runs on 2.2 Bootloader, though as of 4 days ago'ish they added official support for those who want to use a GB bootloader for the easy 2 button CWR/Download mode entry
hi,
I am sorry if this is a dumb question. But i have failed several attempts while shifting to ICS (RC 5 by team-nyx). Every time when i install ROM & kernel via CWM and boot the device (vibrant t959) it freezes on the screen with VIBRANT and SAMSUNG displaying WHITE on BLACK back ground.
i have gone back to JFD and tried several times BUT same result.
I was on froyo 2.2 (build UVKB5) updated via kies and did it but no luck. I followed wiki.cyanogenmod.com/wiki/Samsung_Vibrant:_Full_Update_Guide and did starting from No. 03 --
downloaded Cmenard's Kernel with the ClockworkMod Recovery 2.5
Heimdall Suite 1.3.2 for windows
AND upto No. 9 under Windows ONLY: section
the CWM installs as it says (A blue transfer bar will appear on the phone showing the kernel being transferred. The device will reboot automatically. )
after that i cleared factory, cache and dalvik cache.
then I select install Zip from SD card and chose the ROM (which is from team-nyx.com/index.php/releases).
after 3% it says rebooting and vibrant shuts down and reboots.. when after I clicked the combo (vol+vol-power) to enter the CWM its not there.. so I reinstall using [heimdall flash --kernel zImage] command in PC's cmd. then after i redid the same to select from SD and then ROM installed ok.
then I selected the kerenel which was taken by same source and installation went normal..
after I select reboot from CWM it reboots and hangs on vibrant screen.
I cannot figure OUT WHAT IM doing WRONG..
Please HELP ME..!!!
thank you for your time
I am moving to 2.2 via kies after going back to stock JFD. then i will root my vibrant. after that i will install ROM manager from market. THEN i will try to FLASH to ICS RC 5 + kernel from nyx TEAM.
I dont know what is wrong.. please HELP
From what you told us it sounds right. Have you tried a different ICS rom? Give ICS slim a try. When you Odin back did you checked re-partition?
Sent from my SGH-T959 using Tapatalk 2
You should try flashing the Gingerbread bootloaders using Odin after you flash back to stock. Those bootloaders can run a Froyo ROM as well as ICS so it wouldn't hurt to do either way. After you flash the bootloader then try flashing the ROM.
And try a different ROM like iwillkillyou suggested. Slim is good, but ICZen is very solid if you're tipping your toes into ICS.

Just so that you know, everytime you are using Kies, you are running the risk of hardbricking your device. It is notorius for that and in fact someone last week got HBricked with it.
I don't use ROM Manager and probably won't as long as I have a Vibrant. All you need to do is go back to JFD and pull the CWR from my signature and put it on your internal_sd and label it as Update.zip. Then boot into recovery and hit Reinstall PAckages (might have to do this twice) and your stock recovery (blue) will go to CWR (green) and you can flash away.
Also for more detailed instructions, se my ICS install giude also in my signature.

Thank you for the links.. I downloaded and place CWR inside SD. Without kies can we install official releases via Odin.. is there any way.. im sorry if that is a stupid question
No stupid questions. That is why we are here. I am pretty sure there is a flashable 2.2 stock floating aroung here. I personally don't have it though. Custom 2.2's are at this point tweaked so completely out, that they will blow the doors off any 2.2 stock ROM out there. I usggest Moped_Ryder's ROMs and Fishman's Bionix-redux ROMs. Quality, fast and stable. Not ICS, but everything works and no fear of the dreaded Encryption Bug.
PM incoming btw.

thank you. btw can we Flash to 2.2 via CWM .. directly selecting the ROM from SD .. without Odin
If you can find it, you should be able to. Just put on your card and flash away, taking care to wipe accordingly.
A note on flow though:
2.1, 2.2 -can go into and out of any 2.2 there is laterally.
2.3-4.0 -will need to Odin to stock before going back to a 2.2 ROM. Can move laterally from 4.0 to 4.0 though.
(i.e DO NOT try to restore a 2.2 nandroid or flash a 2.2 ROM when you are on an ICS variant. the /system is completely changed and reformatted. You need to Odin to get it back.)
Moped Ryder uploaded a semi tweaked version of the stock 2.2 build. It's a zip that you can just flash using CWR:
http://forum.xda-developers.com/showthread.php?t=1674519
It comes rooted with busybox and some other goodies, but it's the stock kernel and whatnot. I'd highly recommend Fishman's Bionix-V Mod or Moped Ryder's Slim_Ryder ROMs if you're going to be on Froyo though. They're both great, but I went with Fishman's latest Bionix Mod since I couldn't get bluetooth to work on Moped Ryder's ROM. Which is really unfortunate because I loved Moped Ryder's otherwise.
And you don't have to Odin back to stock if you're just bouncing around Froyo or Eclair builds; only if you're coming from Gingerbread or ICS (2.3 or 4.0).
Keep us updated. I'm curious to see what worked. It's probably the gingerbread loaders. But, who knows.

hi.. I tried again with flashing semaphore kernel through Odin installed CWM version higher than 2.5 to install ICS RC5 by nyx --sorry i need that soo badly so didnt checked anything else ..
@that time I was on vibrant 2.2 UVKB5 (stock)
NOT rooted
I didnt had so called
bootloaders

(i dunno what it means though--have to search )
BUT it didnt worked for me instead freezes at Vibrant start-up screen. So i Couldnt switch back to CWM. I Odin back to JFD with repartition clicked and my vibrant was locked (network lock). Finally, I got it cleared by application named Galaxy_S Unlock by Helroz from the market.
Now I am at the very beginning again. I am now on 2.1 JFD. I dont know WHY this happening to me .. :crying:
gonna try again with GB bootloaders.. BUT Im sick of failing and going back to 2.1 (my friends who are having captivate had no problem)

At the time i was trying it was NOT rooted.. But now i have it rooted because i needed to unlock the network . which happened me for the very first time after flashing back to JFD using Odin..
Thank you guys for the links and thoughts on 2.2 ROMs.. I am not that expert . Thats why i was updating to 2.2 via KIES -- which is not a good idea as it seems with the ability 2 brick the device. I am going to get Bionix-V FishmanMod V4 FULL and install as http://forum.xda-developers.com/showthread.php?t=1441976 says..
It says Boot into clockwork recovery and i think i found something to do that in this thread http://forum.xda-developers.com/showthread.php?t=734164
I have to get ROM manager from market and go through it..
BUT Im damn upset with the RC5 ICS update by nyx being unable to installed into my device.. I will try with GB bootloaders flashed ..
If you are going to go with Fish's ROM, then all you need to do is Odin back to JFD and pull the CWR from my signature and put it on your internal_sd and label it as Update.zip. Then boot into recovery and hit Reinstall Packages (might have to do this twice) and your stock recovery (blue) will go to CWR (green) and you can flash away.
Fish also has a Odin package that you can flash his ROM through Odin and not have to deal with CWR.
ROM Manager is no longer supporting 2.1, so if you do go back to JFD, then it will be hard to get RM. It is out there somewhere but really all you need is the Update.zip from above to do it. I suggest that you stay on Fish's ROM for awhile and read about ICS installs and all the little things that are involved. If you do flash Fish's ROM, you don't need to mess with the bootloaders.
Btw, aside from Kies, messing with Bootloaders is one of the sure fire ways to hardbrick your device. It only takes seconds to flash them, but do it wrong and, well you know.
Good luck and ask if you have any.

thanks alot for the info brother.. some guys told me STUPID.. but YOU guys are awesome.. I am a newbie to this flashing and stuff.. but learned a lot from XDA . Thanks again for the reply. now I have stock 2.1 with ROOT . (rooted cuz i had to unlock the vibrant). I will flash to Fish's 2.2 ROM soon. BTW may i ask you after moving to Fish's ROM and later if i need to move to ICS still can I do it without messing with Bootloaders..
Thank you
That is what we are here for in the Q&A/General sections.
Regaring your question about Gingerbread bootloaders being needed:::Yes and No.
Gingerbread bootloaders were required in the infancy of ICS ROMs bc they prevented what is called "Rainbows" in your clockwork where you couldn't see anything. The options were there but you just couldn't see them. Then as ICS evolved, the need for GB bl's lessened and now you don't need them at all.
But...There's always a but...Gingerbread bl's are recommended by most of the devs for ICS builds because they seem to work better with the custom recoveries that come with some of the kernels. There is more to it but in short, GB bl's are not required but recommended.
If you go to my ICS install guide, in the middle pages and more again at the end, Yosup (highly respected user) and I have a detailed conversation about bootloaders and their installation. Once he got over the fear and did it, he was hooked and flashing ICS ROMs weekly if not more. It is a very informative section of that thread.
Hello. I'm new here but, had an android for a couple years now. I have the tmobile samsung vibrant running 2.2 froyo. Can anyone tell me in detail how to install ICS on my phone? To be honest, I do not understand all the talk about odin and all that stuff. So if you can explain as if it were ICS for to Vibrant For Dummies that would be great lol. Explain in laymens terms please. Thanks
Peppino
Guess I'll post this again: http://m.youtube.com/watch?v=wMQQDpqVNBk
Everything in that video is not all correct. There are some specific parts that are left out.
OP, I understand you want to simplest way to go from 2.2 ->4.0 but in reality, you need to eventually know how to use Odin, or when you get stuck at a bootloop or your CWR gets corrupted, your next thread will be "Help, I brivked my phone".
Check my signature for the How to install ICS and above all, you need to read, read and then read some more (case in point, this was already answered here Trouble with my vibrant...).
Good luck and if you have any questions, use the search function and/or Google, as this phone has been around a long time and most questions have already been solved. If not, then just ask.
hi, It is always better to go ICS from the beginning.. which solves many problems. So in order to go back to stock you should use ODIN. It is very easy ONLY thing is DONT DISCONNECT USB connectivity while the process is running.
After that you will need some things.
ICS ROM to flash (try ICZen which works great )
GB Bootloader
CM7
update.zip (CWM) which can be found in woody's signature. [Installing ICS ROMs; A Vibrant Step-by-Step]
Once you are in stock 1st flash GB Bootloader through ODIN (DO NOT do anything until it is flashed)
then flash CM7 (GB ROM b/c its suggested to go ICS from GB rather than from 2.1)
then flash ICS ROM on top of it. initial boot will take up more time.
voilaa..!!!
Always do full wipe (data,cache,dalvik) in between flashes.
there are many ICS ROMs available .. READ instructions carefully.
Note: these steps are taken from threads I referred and followed by me.
