Is it possible to flash the CM7 rom over MIUI if I wipe data/cache/dalvik? Also, is it possible to SBF to 2.3.4 and just back that up for future flashes that require SBFing or does it have to be a fresh SBF install?
You can flash safely over MIUI after wiping data, cache and dalvik. If you want a stock backup, you can first, be on stock 2.3.4, then backup using the bootstrap recovery. Then you can always restore that backup if you want to get back to stock. The same can be done with CM7 and MIUI if you'd like.
EDIT: And SBF'ing usually means you cant get your phone to turn on or boot right. If this is the case, the stock backup wont replace an SBF since you need to get into your phone to access bootstrap. All this will do is be a quick way of getting back to stock if you dont want a custom ROM anymore.
Thanks. I just wondered why they say SBF to 2.3.4 before flashing MIUI or CM7. Now if I have a stock 2.3.4 backup I should be fine?
People say to SBF first because its a clean start and a fresh install. It makes it so there are no residual files sitting on your phone from other ROMs that you dont need on your new ROM. I have never had a problem flashing over CM7 with MIUI or visa versa. The only time SBFing is absolutly necessary is if you are on a different Android version that the ROM requires, like 2.3.3 or 2.3.5. Both MIUI and CM7 are based on the 2.3.4 kernel so its safe to flash over eachother. However, Eclipse, for example, is based on the leaked 2.3.5 kernel. So if you wanted to switch between Eclipse and others, SBFing will be necessary.

I'm new to the whole modding scene so I have a few questions before I unlock my bootloader, install Ken's Gingerbread, etc.:
- I'm currently on Gingerblur 4.5. To get back to "stock" (which is the starting point in the "[VIDEO] How to upgrade to Gingerbread" thread), I have to find .83 and SBF lite down to it, root, and then follow the video? Or can I just do it now without reverting back to stock (Gingerblur 4.5 does have webtop enabled FYI)?
- How do I make a backup image so if I want to revert back to stock I can easily do this? Is this done via CWM? Or are these backup images easily found in the forums?
- After doing the [VIDEO] thread as mentioned above, if I want to install another custom ROM will I have to do this process all over again or can I just enter CWM, select a .zip, and it will wipe everything and install it?
Thanks for the help.

You might as well flash the 1.83 .sbf just to be safe. You'll be wiping everything when you upgrade to gingerbread anyways.

By "backup" image I assume you mean "method to get back to 1.83". This is easily found in the forums. Infact, here is a link that contains the files needed to go back to 1.83:

You won't be "selecting a zip" in cwm, as most of the installing of roms is done in something called "Fastboot", but yes, it is that easy. You will just be going into fastboot and it will wipe everything and install it. You don't go back to 1.83 ever again (unless you want to). You can switch from rom to rom to rom very easily.
Thanks for the help.

I hope this helped. If you need more help feel free to pm me (I just got into the modding scene a few weeks ago, but I've picked it up pretty quickly! )
Thanks a bunch!
Just to followup:
- By backup image I meant if I want to revert back to "stock" Gingerbread (.91). I doubt I'll ever want to flash back to .83 Froyo. Or can this "backup" process be completed using Fastboot and Ken's Gingerbread ROM found on the forums?
Hmm, is this where I find the .83 SBF: http://forum.xda-developers.com/showthread.php?t=1125944
I'm assuming I download the FULL, not the SERVICE??
And why does it say at the top that all are unlocked?

To revert back to stock you simply use fastboot commands with the stock system.img and boot.img files in ken's gingerbread rom found on the forums.
Regarding your 2nd post check pm.
Just chat via pm from now on (unless you want other people to answer of course)
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 just flashed CM7 pre beta 3 after flashing almost every rom in the forum available and not satisfied by the GB ROMs i want to go back to stock froyo.
I have already downloaded Bell Froyo 2.2.2 gobstopper file,

Can any one guide me to how to go back to stock.

Use tenfar's unlocked CWM.
Cheers!
Testing rit now, report with results as soon as i get the stock love
Flashed without any problem,
factory reset, wiped cashe
installed unlocked bell zip
after reboot red led shows up and phone reboots.
I think i am stuck in boot loop
Now what to do ?
I have managed to get back to Aura ROM
now will try to go back to stock.
Booting Aura rit now (y it is taking forever to boot )
Finally out of CM7
Now trying to go back to stock
Well, not sure what happened there, you can apply the ihop_bell again to see if that fixes it.
Cheers!
I managed to get back to Aura ROM and tried to flash bell 2.2.2 zip and process aborted i think that zip only works with tenfar's unlocked CWM only that managed to fully flash the rom but stucked with boot loop.
Now going to flash Alien rom (personally Aura removes blot and adds his own crap)
Nop bell stock 2.2.2 is giving error in all 3 recoveries
What to do ?
Have you tried fruitcaking?

is it any good ?
Hi,
If you backed up your pds partition, try restoring that. Probably some sbf you tried modified it, changing the signature maybe.
Cheers!
I didn't backed-up any thing (no need of backup)
if u have any then let me have it
Nop dont have any backup, didnt bothered to keep any backup. now i am thinking i was so wrong
Hi,
I just threw that out there, it's the only partition that I don't touch, but sbf files can modify it, since I got my replacement phone I have never used a French/Orange/ATT whatever sbf, so that's probably the difference. My backup is the 2.2.2 Gobstopper really, I also have a pds backup but it's useless for other phones.
Only other idea would be to change the radio first, there are radio only sbfs out there, go for the .15P one for Bell. Once on my previous phone when going from Telstra and French there were issues due to the radio if I recall correctly.
Cheers!
I'm finally getting around to updating my phone to 2.3.4 (bought a house over the summer and haven't had time to play with updates).
I currently have a rooted 2.2.2 Atrix with my apps/data backed up via Titanium Backup and saved off to my desktop for later restoration if needed. Except for Root and APN mod, the phone is otherwise stock.
I'm not necessarily interested in using a custom rom right now (though a wipe of data/apps may help clean things up), though I do need root, APN hack, and plan on installing the full-linux-webtop mod (if I can get my laptop dock to work reliably...). I assume things have evolved since the old posts I've come across about updating when it first came out.
What is the best method for updating to 2.3.4 at this stage?
thanks,
- David
In my opinion you should still unlock your phone even if you are staying with a stock rom. It is way easier to flash with CWM method, even if you are staying with a stock rom. Look at Fruitcake 2.3.4 and you can also flash a fruitcake 2.3.4 webtop. If you mess up your webtop hacking on it to get it just like you want it, your can reflash just the webtop.
Of course after you unlock your phone, you will probably get the itch to look at some of the custom roms that are out there. A lot of them are basically the stock rom with customizations built in.
I'm on a milestone x2 with paranoid android installed and i've decided to go back to stock. How exactly do i install this 2.3.6 nandroid back up http://forum.xda-developers.com/showthread.php?t=1542456 ? The instructions on the site, from what i gather, aren't for my model phone. i've tried a few different methods and can't seem to get it to work; mainly installing as rom from cm7 recovery. can it be installed from cm7 recovery? i'd really like to not have to sbf on account of how much of a pain in the ass it is.
