multiboot CM7 to Froyo - Galaxy 3 Q&A, Help & Troubleshooting

i may go back to froyo for a weekend, going to a 24Hour GT race, would like everything working properly, vid, cam etc. basically nice and stable.
if i multi boot to froyo do i have to wipe cache/dalvik cache and sd ext. sd and sim inserted or not?
tried this before, ended up with continuos fc of apps when i inserted my sd card.
anyone give a step by step, and how to restore back to CM7?
(secretly hoping CM& is sorted by then, well, we can hope, eh?)

For g3mod,
Use kmapp by rapier07 to configure your multiboot settings
Enable multiboot
Enter recovery backup img and flash the froyo ROM img via multiboot
This will automatically backup your current ROM erase system, cache,etc., and flash froyo on your ROM
If you want to revert back to cm7 just flash the img you previously backuped.
Alternate:
Enter recovery backup everything
wipe everything except sdcard(wipe sd ext)
Flash img or update zip
When you want to revert back to cm7 just restore previous backup
and everything will be back
You will definitely get fcs if you don't wipe sd ext while using second method
In first method you don't need to do anything extra

nice on allspark
first option seems the best i have KMApp 1.4.1 installed, but i cant find the multiboot options, data-kernel-tweaks and data conversion using menu button available.....
edit-running G3MOD 2.5 Kernel, forgot to say.

Didn't you find multiboot in data preferences . I think you find it right away on the main screen
Enable multiboot
If you don't try 1.3 which same great features
I can't confirm this as I am on fugumod and cm9 (not supported)
Edit: sorry dude
It is multiosdata

use option 2 then!

@Skivit
Check my sig for multibooting...it's all there....but with g3mod 2.5 multiosdata ain't working somehow....dalvik gets wiped when u switch rom....automagicaly....only thing u should do is data wipe when switching to froyo & restore froyo data from multiboot....any [Q]?....just say

if i hit problems, i'll give you a shout!

If all the data in your phone is really very important then also have a nandroid backup in case multiboot fails
Also copy your contacts to sim using contact2sim or save them on your sd card just in case anything fails
Multiboot, nandroid backup and every possible way you try to backup data are extremely unreliable and I lost so much of my data lots of times believing they would work

well....i never lost anything with multiboot.... you don't need full nandroid backup coz "backup_data" in multiboot is working perfectly....and only thingy is that due to multiosdata not working properly(e.g. data partition never gets restored)...so you have to format data & sd-ext partition before restoring other OS data to avoid any fc's due to overwriting data over existing data....that's all....otherwise it's safe...

Nandroid backup HELP!! :(

I'm freaking out. I was running Leedroid and switched to Coredroid. I did a nandroid backup like I always do and now I'm trying to restore back to Leedroid and it doesn't do a full restore. Pretty much everything is gone. PLEEEEEEEEASE someone help me. I can't even download stuff from the market. I'm so frustrated!
I would try restoring my phone to stock and then attempt to restore leedroid..
also do you make sure you restore phone back to factory and wipe dalvik cache?

Or u could try reset data/cache (factory reset) in CWM console, and clear out dalvik cache, and then restoring ur backup.

I went and got a new phone today. I was able to "unroot" it and get a new one. I'm rooting it as I type using the Simple One Click method. I should be able to just use my nandroid back up then to get back the the Leedroid rom right? I think what may have happened is I didn't do a ext4 whipe when I went from Leedroid 2.x to 3.x so when I went to switch back from Coredroid which uses ext4 it got messed up. Maybe?

As far as I know, not all ROMs support EXT4. So be careful when flashing a ROM that does not support EXT4 on ur phone if ur /data is etx4 formatted.

Oh yeah for sure I understand that. How do you switch between ext4 and ext3? Does using titanium backup work between the two? As in I flashed an ext3 rom backed up my apps using TB and then flashed an ext4 rom. Would I be able to use the Titanium backup at that point?

TiBu:
Since Tibu backs up apps and data, and not any file system related info, you should be able to backup and restore using it. It worked for me when moving between ROMs since I got my Inspire, and I didnt' format my /data to EXT4 on my early ROMs.
But nandroid might not work. I tried I think when I got my phone a couple weeks back to restore data and it came back with MD5 check failed.
EXT4:
1. Going into CWM and resetting to factory formats data and cache partitions. This should be getting it into the default file system (I think this should be RFS, but not sure, and definitely not EXT4).
2. I have a script that can be used to format data partition into EXT4 (got it from Android Revolution 5.1.x ROM thread). I run it when I know the ROM supports EXT4, but does not do it when installing ROM.
E.g., Android Revolution 5.1.x supports data as EXT4, but does not do it.
Gingerbeast 2.1.x supports EXT4, and auto converts too.
I am attaching the script to this post. Copy it onto ur SD, and run the steps in sequence mentioned below.
1. Get into recovery
2. Factory reset (formats /data and /cache)
3. Wipe dalvik cache (under advanced menu)
4. Run the script attached to this post (optional, and needed only if ROM does not auto convert)
5. Install ROM of ur choice
6. Reboot

Ok great so it must have messed up the phone while doing the nandroid restore then. When I did the TB I do remember it coming back with errors for a lot of things. Could that be because it was running Sense 3.0 vs 2.3 (the backup was done on 2.3)?

The way I see it, Sense is an optional set of components over base android, and has nothing to do with TiBu. The ROM I have on now doesn't have any traces of Sense

Hmm and it backs up/restores just fine?
Ok so I just rooted my new inspire and the boot logo is something completely different when I restored from my nandroid backup. Can these back ups become currupt? The only thing I want from this back are my texts and one of my apps everything else is fine without.

[Q] Nandroid Backup Question

Can you use a Nandroid backup across any ROM, or is it specific to the one you backed it up on? Sorry if this seems like a dumb question... I just switched ROMs cause I'm trying a few of them out, but for some reason it's saying my SIM card has no contacts. I'd also like my SMS's back too. THanks
I think so, wait for confirmation as I'm not 100 percent. But I do believe that is one of the main capabilities of a nandroid.
Sent from my Inspire 4G using XDA App
@OP:
Nandroid backup holds good ONLY for the ROM u flashed.
1. Flashed ROM 1
2. Took a nandroid backup
3. Cleaned and flashed ROM 2
At this point, the nandroid backup at step 2 will not hold good for ROM 2. If u restore it after step 3, u'll get back to ROM 1.
If u want internal stuff like contacts, etc, u got to use an app like TiBu.
1. Flashed ROM 1
2. Took a backup of user apps and data with TiBu
3. Cleaned and flashed ROM 2
4. Restored user apps and data using TiBu
For contacts, u wud need to back up and restore system data (only) "Contacts and Storage". This is the only system data I have been able to successfully restore across multiple ROMs.
Do I need to be flashed to that ROM to restore a backup of it? I've been getting stuck at the HTC loading screen, and after using HBoot or w/e and returning to stock, tried using CWM to restore from a backup. Do I need to flash RCMix3D ROM before I can restore from the backup made from it?
Restoring a nandroid backup from rcmix3d will put you back to that Rom with all apps and data you had at the point you made the backup. If you are restoring apps and data using titanium backup, you will have to flash rcmix3d first.

I thought so too, but all it's too is getting me stuck on the HTC boot screen. Been like that for 20 minutes so far. Dunno what I did wrong, but I'd like to get everything back to the way it was
A couple of my backups refused to flash. Do you have more than 1?

I have two for each of my ROMs, so four total. Created days apart though.
Do they all hang when booting?

A nandroid backup makes a complete copy of your phone as is when you perform the backup, obviously this includes the rom you are currently running.
If you are running rom A and do a nandroid and then flash rom B, and then restore the nandroid backup you previously made you lose everything you've done since the backup and you are back where you were on rom A when you did the nandroid.

Check out if both are EXT4 compatible.
ROM 1: EXT4 not compatible
ROM 2: EXT4 compatible
1. Flash ROM 1 (formats to non-ext4 and flashes ROM)
2. Nandroid backup of ROM 1
3. Flash ROM 2 (formats to ext4 and flashes ROM)
4. Nandroid backup of ROM 2
...
5. Restore backup of ROM 1
This could fail since partitions are ext4 and ROM 1 is not ext4 compatible.
Here is what I do as a standard before restoring any backup:
1. Data/factory wipe
2. Dalvik cache wipe
3. Restore ROM
This worked all the time, except once when I got MD5 error (probably cos I backed up on an earlier version of CWM, not sure though).
@biglittlegato
Yeah, they all hang on the HTC screen. It's starting to piss me off. I know that it's a risk with rooting and stuff, but I'd rather just not have to start all over with my content.... again. I just flashed a clean RCMix3D, so maybe it will let me restore my backup from that.
@Perseids
That kind of thing may be obvious to you, but not to those of us who are new to Android and rooting. Hence why I was asking in the first place. I get that I'd lose everything I haven't backed up... but right now I seem to have lost everything period, as none of my backups want to work for some reason.
Maybe I am doing it wrong? After getting to the stock version of 2.2, I go to ROM Manager, and then to manage backups/restores. I click on that, then hit the backup I want to restore from, and it's supposed to work. It does it's thing, then just freezes on the HTC screen once it reboots. I watched it and read the script, and there were no errors or anything that would give an indication as to why it's doing that...

Don't worry too much. EXT4 is a partition type. Most recent ROMs support this. Just make sure in the ROM thread OP if it converts partitions to EXT4 (if yes, what all partitions).
I was just reading the script while it was (trying) to restore, and it said something about erasing boot before restore... is that normal? I just did a full wipe, flashed to the ROM I did the backup from, and the backup seems to be stuck again.Dang.

Restoring process erases everything, and restores. Compare this to norton ghost partition restoration process.
I guess I might as well just start over from scratch. It was only a few days worth of pictures/videos/texts and stuff, so not a HUGE loss. Still, wish the backups had worked as they were supposed to. As of right now it's still frozen on the HTC screen hah.

Data on SD card will NOT be deleted unless u choose to format SD card. All ur pics, vids, etc reside on ur SD card.
It doesn't show up anywhere. I just booted into CWM, and tried to select one of the backups, but it said "no file found". WTF. Sooooo it's telling me the backups are there, but don't contain anything I think. Nice.

If you're backups are not restoring you will lose data that's part of the ROM. Your pics and videos would definitely still reside on the SD card. You'd have to format SD to lost those.

1. A flash over the top with no wipe will keep your apps. If however the dev has done an update with a new base, a wipe is recommended.
2. Do a nandroid backup and try the kernel. I get fantastic battery life on coredroid with it.
3. Yes but NEVER rename the folder else it will never restore. It will fail on md5 checksum error.

If you wanna backup your apps, use Titanium Backup. It's awesome, use it all the time. It also backs up data.
Also, you need to manually wipe all data before you flash
Kernel is optional, but you should try it.
About the backup - put it in the PC, i have. If you ever wanna delete the backup from your phone but want to keep it on your PC, then delete the contents of the backup folder in the phone, not the folder itself. I have 2 backups on my phone right now. Consumes waaaaay too much space. Got 5 on my PC
OK..... So if I use titanium backup now for some apps and install another Tom it will be there even if I wipe data and stuff?

wipe data/cache question

I understand the basics of modding...i currently have an AT&T skyrocket running the SKY ICE Rom. I've ran a ROM backup via Rom Manager. My question is, if i want to try a new ROM then i would run a backup right before installing a new ROM. then go through the same process as when installing the first ROM (wiping data/cache) right? Wont this delete my backups? Or what exact data is it wiping when you do it? and is it safe to have an external SD card in the phone when doing the wipe? I dont want to lose any information on my sd card and its always worried me so i take it out. thanks for any help
When you install a new rom there is no need to back up again if you already have made a back up recently (if it is a old back up then make a new back up and if not required delete the older back up as they consume a lot of space). Regarding the loss of SD card data, you need not worry only the data on phones internal memory gets erased.the back up which you make on rom manager is safe as it is stored on your SD card.hence,there is no need to take out your SD card when installing a new rom.

so doing a rom backup doesn't backup all your current apps and settings? i hate losing my aCar info and my plants vs zombies saves. when i did my first nandroid backup (before i flashed my current ROM) i had my SD card out i believe. and when i did the wipe through CWM it didn't completely wipe the phone out. i believe all the folders where still located on the phone.
i just want to backup my phone to the way it is currently and try out some new ROMs to see if i like one better and be able to go back to this one if i decide i dont like the new ones. i know that i can back up all my apps and user data with titanium backup and reinstall apps and such to a new rom if i choose to stay with it.
thanks

this is a good explanation. I did a data/cache wipe, but was wondering what stayed, and what goes away. I just updated to Franco's kernel (I'm using 4.0.4 ICS) and tried to get back to the stock kernel. well. I failed.

Nandroid Skips TitaniumBackup?

So I just switched from Prime to Revolution ICS. I made a nandroid before I flashed, as well as a full system+data backup in TitaniumBackup, but when I went back to try to restore TB in ICS there was nothing there. Oh, of course, I thought. I should transfer it to the external SD card so I can get at it after I flash. So I go back in and nandroid restore the Prime ROM, but it hangs on the boot screen.
Is this because ClockwordMod 3.2.0.1 skips the internal /sdcard? Did it then get wiped when I flashed to ICS? Because if so, that seems like a major flaw of which I was never warned when flashing that recovery. I tried to extract TB from my nandroid using unyaffs, but I can't find anything useful.
Any idea if I can get my old TB back?
TB works fine. Look in the TB folder on your internal or external card wherever you have it and if files are there then it should be okay.
Did you flash prime kernel when you restored nandroid? Recovery doesn't make back up of kernel so you need to flash one after restoring backup that's why it probably hangs on boot screen.

Dangit, I was hoping to get back to edit my post before somebody noticed my stupid mistake. Forgot to flash a new (old) kernel when I nandroid'ed. I'm flashing up to ICS now to copy a HC kernel to my external SD, so I can nandroid restore the old ROM and kernel together.
Thanks, though. I'm sure this will fix it. Booting now.
Well, I got restored okay... but the TB folder is nowhere to be found. I'm thinking the SuperWipe script cleared my sdcard (internal) since it's basically empty. Good to know if I ever wanted to, you know, not erase all that stuff that CWM nandroid skips. I'm a little perturbed about that, but it's partially my fault for assuming it all worked the same as my Evo. Live and learn.
Well super wipe script does erase the internal card, at least that's what it says. Personally I always change TB backup folder location to external card as soon as I install titanium.
