i have my vibrant running obsidian rom with no lagfix. i want to revert it back to stock tmobile 2.1 image. is this possible without using odin? can i just flash a stock image and kernal via recovery?
I was able to do it by flashing the stock kernal and then a nandroid restore.

Yep, once you flash a 2.1 kernel, a nandroid would work. Or flashing any 2.1 rom after that. dont reboot between flashing the kernel and rom or nandroid restore because it wont boot.

greetings all, my phone setup is in my signature. i am running eugene's latest Franken-TWIZ rom using baseband JI6 and JAC's 1.1 OC/UV kernel . I have set up my phone for use with odin with the proper drivers and plan on flashing back to stock in a month or so before the Froyo OTA.
my question is, can i simply run odin and flash it back to stock using this guide link posted from the bible directory?:
http://forum.xda-developers.com/showthread.php?t=734475
i wanna make sure if this method is safe considering my kernel and baseband have been modified using Eugene's latest rom.
I am no expert but I flashed back to stock rom from ji5 which had a different kernel and all went well.
Yes it's safe. You are essentially erasing all data on your phone and returning it to stock so it doesn't really matter what base band, kernel, or rom you are currently using. However, unless you want extra steps in the restore, if you are using voodoo, disable it before you do anything!

i need help, i restored my nandroid backup which s the JI6. i am using the fusion 1.1 then after that i reboot now after the restore now i am stuck at the vibrant. please help. i do have the stock kernel. no lagfix.
i can go to download mode and recovery mode. will i now do the odin?
How long did u let it sit on the vibrant screen? It usually takes a while
Sent from my SGH-T959 using XDA App
I can't really follow. Did you not like fusion and want stock instead? Which fusion did you download? Did you follow sombionix's instructions? Also agree about asking how long you waited. What exactly is it that you want?
I like the fusion 1.1 but I would like to go back to stock JI6 first because I will unlock the phone to other carriers. unless I can unlock the phone while I'm rooted and using a custom Rom.
I'm back to fusion by doing a nandroid restore of fusion 1.1, but why does my nandroid backup of the ji6 isn't working. like I said its stuck at the vibrant screen for more than 5 mins.

Do not do a nandroid restore, instead try to install Ji6 over fusion using ODIN or Rom manager.
does unlocking the phone have something to do with the Rom or rooting? cause if not, I wouldn't be going back to JI6

You don't need to unlock your phone to root of flash roms. Ive done both w/o unlocking my phone. Now using odin flashing I don't think you need to but I'm not sure

you misunderstood me, i will unlock my phone because i need to. in a few months i will be no longer be with T-mobile that's why i need to unlock the phone.
Try flashing the JI6 modem, then reapplying the nandroid backup, because fusion 1.1 uses the JI2 modem.

i'll try that after i get the codes for unlocking this phone. do you know whether i can unlock the phone even if i am rooted or using a custom rom?
to get the unlock codes, I believe you have to be on stock firmware JFD

but getting an unlock code can be obtain from tmobile. If I do get a code can I use it with custom Rom?

I thought that you cannot get unlock codes for this phone from t mobile yet. Anyway I used the method that you can find in the android dev forums, which I think only works with the stock firmware
By the way did you unbrick your phone?
Sent from my SGH-T959 using XDA App
I had the same issue as you. Stuck on the Vibrant screen after the nandroid backup. Turns out I had the wrong kernel.
You need the Kernel-Vibrant-StockJI6.zip kernel. Apply that kernel after you do your nandroid backup.
Search the forums for it. If you can't find it, I will upload it later.

what custom rom did you use? and did you apply a non stock kernel in the rom?

I used Bionix Final.
I was on stock JI6, went to Bionix Final with stock kernel, tried to nandroid back to my JI6, got stuck on the Vibrant screen. Got the JI6 kernel, and I got back.
I've attached the kernel for you if you need it.

I have had this same issue, when i did a nandroid back up while on stock ji6 then loaded bionix 1.9 on ji6 kernel and tried to reload my nandroid back up it soft bricked my phone. i have never been able to load a stock ji6 nandroid back on a bionix rom with it soft bricking. So i just made a back up when i was on 1.9 with ji6 and then created another back up when i switched to the ji2 modem just to cover all my bases. Side note always make sure your not loading a back up that has programs or mods that will not be compatible with what ever new rom or kernel you will be installing or you will soft brick every time.
So I started out with 2.1 stock on my vibrant, and used clockwork mod recovery to flash nero v3 w/ voodoo, before doing this I created a backup in rom manager of my entire system while still on 2.1, if I wanted to return to 2.1 I would just disable lagfix and restore backup in rom manager right?

First one question.....Why would u ever want to go back to 2.1?
I usually just skip ROM manager all together and go directly into CWR. Then select Back up and Restore then scroll down to Restore option. Then select what u want to retore. Its pretty self explanatory once u get into CWR.

You will need to flash your 2.1 kernel as well as a nandroid backup doesn't backup the kernel.
Nero V3 w/ Voodoo is super duper silky smooth. I would never think about flashing back to 2.1 nanadroid from it. I forgot about the kernal.
Ya, I don't want to, but eventually, lol, when official 2.2 comes out, I wanna get that, so even if I just rooted, then used rom manager to flash nero, my kernel is now permanently changed? How would I change that back if it wasn't saved in rom managers backup?

why use your backup, why not just odin back to jfd?

Lot of people answering your question with another question.
Sano said it right...you're fine to restore your backup AS LONG AS you also flash a 2.1 kernel separately since nandroid doesn't back up the kernel.
So how do I flash kernels?
Sent from my SGH-T959 running nero v3 in XDA app
Same way you flash a rom with clockwork.
Where do you get a stock firmware
Sent from my SGH-T959 running nero v3 in XDA app
Just flashing nero v3 rom changed my kernel?
Sent from my SGH-T959 running nero v3 in XDA app
Yes cause the kernel are different in 2.1 and 2.2, which Nero is. U have to flash a 2.1 kernel if u want to use that nandroid.
Sent from THE Vibrant......
So would you flash the 2.1 kernel before or after downgrading, also where would I get a stock 2.1 kernel
Sent from my SGH-T959 running nero v3 in XDA app
First get the kernel from the bible put it on your phone . Once you have the cwm flashable kernel just nandroid back then before rebooting flash the kernel .

Thanks ill try that once official 2.2 come out

Well my question is basically how can I flash a different ROM without always starting from 1.26 and use gladroot then update and update again then the updated ROM or a new ROM?
thanks
Sent from my MB860 using XDA App
Once you've installed a rom using CWM you can just use CWM to flash a different rom.
If you want to be a little more cautious, you could use CWM to create a back up before flashing a rom. Then you can just restore to the back up and then flash the new rom.
So I wipe first then install the new ROM or can I just install from sd?
Thanks
Sent from my MB860 using XDA App
I created a backup before flashing a rom so I restore to that backup and then flash the new rom.
I think you could skip that step and just flash the new rom right over the old rom, but I prefer to stay safe and flash after restoring.
Great thanks

i was just wondering that can we flash 2.1 eclair without using odin and by using cwm ...... i tried to serch on the forums but no help
No, there is no stock 2.1 zip that I'm aware of. There is a stock 2.2 (closest you will find) flashable zip for recovery. You can get it here http://forum.xda-developers.com/showthread.php?t=1674519. Hopefully that will help....
