Hot Swappable Roms? - Nexus One Q&A, Help & Troubleshooting

Lets say I have SD Card (A) and SD Card (B). SD Card (A) has the stock Rom on it, but I want to try out some other ones without running my settings. Is there anyway I can use SD Card (B) to "test" other roms and then if I don't like it I can put SD Card (A) back in and everything fine?
Sorry, I searched didn't find a thing.

No way. The ROM lives in the phone's RAM, not on the sdcard. Sorry.

Great, thanks for your help. I was unsure.

You can always set up a rom use it the way you want then run a nandroid backup go into the sd card and go into nandroid and rename your nandroid as to what rom it was.. =] And then boom you have backups of every rom you tried and what ever settings it had =] Haha

Yeah, you can always swap between NANDroid backups, but it's not exactly convenient. It cannot boot up from the SD card.

SD Card and BART Question

Quick, Simple Question...
I'm Looking to Change ROM (Again) and want to start Fresh i.e, A fresh Partition and Reformat SD Card, but like the fact I can, Currently, go back to my BART Backup at anytime.
If I was to Format/Wipe my SD Card, I'm assuming my BART Backup goes with it, so, If I copy my current BART backup on to my desktop, and I put it back on my SD card after Formatting can I Expect it to work? Or is there something Deep seated that I cant get to within Android needed for it to work that may disappear when starting fresh?
Cheers Guys!

Switching Micro sd card after rooting

Hi there to everybody. i have a Tmobile G1 :
Installed Htc Hero Sense, Firmware version is 1.5. I have 1gb micro sd card on it when i root the phone. now i am replacing it with 8gb micro sd card.
every time i put the 8gb sd card on it, the phone keeps freezing and will not continue to boot up. i then returned the 1 gb sd card and the phone is working properly. how can i change the sd card to a bigger capacity without the phone freezing? do i have to re-root and restart the whole process on the phone? any help, guides will help. Thank you in advance.
......umm...lol..imma leave this one alone
just copy the content of the old sdcard, some Hero rom store some info there
it wont hurt to try it
also, did you have any partitions on the old sd?
partition your sd card and flash a 1.6 rom with auto a2sd
I did try to copy the whole contents of the sd card, but it does same thing, freezing and it wont boot up.
using 1 gb flash the Amon RA recovery image....and then do a Bart Backup...this backup will backup all your apps and also the rom..then put that backup file and put into the new sd card...and then go into recovery and do a bart restore....

Um...partly true but you don't need to install a 1.6 donut ROM
TO OP
You have to repartition your SD card (~7400 MB Fat32, 512 EXT3, 96-128 Swap?) whichever you want.
If you want to reinstall all your paid/free apps, then you will have to back them up on your 1 GB card using a backup app (App manager, astro) or just use Mybackuppro if you want to back up everything (contacts, data, etc)
transfer the backupped files back onto your newly partitioned 8 GB card. Boot up the phone with the new card in it, and reinstall all your apps
OR the easier way (but you lose all your data)
Partition card
wipe phone/dalvik/ etc
fresh Reinstall
The old sd card appeared to be partioned.
you need to make sure your swap and ext. partition is the same size as the one you have on your old one. ex. if your 1gb have 96swap, 512ext. then your new one should have the same swap and ext size. rest goes to fat32. First thing you should do is do a nan + ext. backup using the recovery image. Then copy everything from the old SD card to the new SD card. Then do a nan restore. That should restore everything on your phone plus whatever is stored in the ext. partition. The likely cause of your phone freezing is because the stuff in the ext. partition is not there anymore.

[HELP] New SD Card

Hi guys,
I'm planning to get a new SD card for my G1 to replace my current 4GB SD Card.
Currently, I'm running Cyanogen 5.0.8 DS and Apps2SD.
If I change to a new SD card, will anything be lost? or is there anything that I will have to take note of in particular?
Thanks!

Yea same. i wanna use a 16GB cause my 4GB is almost full. and i dont want to lose all my apps i have installed from Apps2SD. cause ik in ubuntu when u mount it shows the the partition part of the SD card. but idk how i would transfer apps from my 4GB to my 16GB
You will lose all your applications on your SD card, which should be 98% of them. To prevent this from happening, go to the Market and download an application called Backup for Root, it is free. Check APK's and anything else you want and hit backup. The backup will be created on your (old) SD card. Take your SD card and put it in your computer and open it up, you will see that there is a new folder in it called Backup, copy the contents onto your computer. Put the new SD card, fully partitioned, into your phone. Go to the market and reinstall Backup for Root and also place the contents from the backup folder onto your new SD card, check all that apply in the application and hit restore.
Another option:
Using your recovery image, create a backup using Nandroid or BART (I use BART). The backup will be on your old SD card. Take that backup and put it on your computer. Put the BART/Nandroid backup onto your new SD card into your phone and through the recovery window restore it. Make sure your SD card is partitioned in the exact same way, I have not done this method before so be careful. However, if this method works it will ensure that all applications stay intact as opposed to the previous method where some applications just seem to break, it is inevitable.

[Q] SD card

I only had a small microSD when I rooted. I ordered a bigger card. When I get the new one can I just copy the files from my original card to my pc and then copy them on to the new card? Maybe a dumb question..I am new to rooting.
I have Titanium backup,what do you recommend should be backed up?? I will have a 16gb card coming. Should I back up everything?? Thanks for any help you can give me. Great forum..I am hooked1
Yes, you can simply transfer the files from card to card. I do it all the time. You don't even need to employ titanium backup at all unless you are changing or reinstalling roms, or doing a factory reset and re-rooting. If you ARE doing that I would suggest doing the "Apps + Data" batch backup. This will restore applications in there exact state.
But if you are just swapping memory cards the only thing I would suggest is that you take advantage of any backup to-sd card features your apps might have before you copy files from one sd card to the other. Then you can restore anything that apps might save on your sdcard(which Titatium backup by the way doesn't save anyways).

question about backups

So, I've gotten good about making backups of everything before flashing another ROM. My question is, where can I access the backups made in CWM recovery so that I can transfer them to my computer in case I need them later?
Inside the clockwork mod folder on your phone.

Personally, I gotta seriously recommend saving your backups to your EXTERNAL SD card. One of our main fixes it to wipe and start over...doing it that way you'll lose whatever is on the phone's internal SD. I went out of my way just to free up 1.6gb of external sd space just for that very reason....1.6 is a lot when you have about 14-15gigs of music and not much more than some apps...got lucky and found some old TB folders .
//Sideloadable backup and recovery would be the shiznizzle.

You're right! I finally found the clockworkmod folder. I didn't realize when I flashed one of the new ROMs that it moved my stuff to /sdcard/0 and found it in there. Moved my backups to my external SD so now I'm golden. Thanks!
I keep a copy of my backups on my PC as well. If my SD card goes bad, I can copy the backups to a new SD card and restore as required.
Always backup to external and keep on hard drive!
