Right now I'm using CM 6.1.1 on my Nexus One. When I flashed CM for the first time I wiped my SD card right after I installed the ROM, so I really don't remember too much about what happened to my apps or anything like that. So, my question is, if I want to install CM 7, can I just wipe my phone with ROM manager right before installing it, and then not wipe my SD card afterwards? Will the apps, pictures, ect., that is on my SD card right now magically appear untouched on CM 7? I guess I'm just not sure how the SD card contents will be affected when flashing ROMs, and I'm not sure if after you flash a new ROM, the ROM can use all of the stuff that's on your SD card just like the ROM you had before did.. Does that kinda make sense? I feel dumb for asking all this. Also, when I save a backup of my ROM, the backup will just be a copy of all of my phone's internal memory and the operating system, right? And when I wipe my phone and install a new ROM, the new ROM just replaces all of my phone's old contents? So if I ever flashed my original ROM again, it'd bring back all of my phone's contents, system memory, operating system, apps installed on the phone, ect?
Thanks for taking the time to read my long, poorly written batch of questions Help would be very very appreciated!
SD card isn't touched when flashing ROMs.
You can restore your backup and it'll be all like it was.
If you use DT A2SD - things start being more complicated.

Yes, you can leave your SD contents as is, they won't be touched.

Pictures, Music, Videos etc that are stored on the SD card will remain untouched by flashing a new ROM, however apps are a different story. Basically you've got two main types of Apps on SD cards. The first is froyos implementation which is basically used to free up space on the phone memory but will not survive a wipe or flashing a new ROM. The alternative is Dark Tremors A2SD which uses a dedicated partition on your SD card (Created through recovery) to store apps by tricking the system into thinking the folder on your SD card is actually on internal memory. Once a new ROM is installed over the current (Which obviously must use DT A2SD also) these apps should be available again with their settings etc remaining.
I guess I'm just not sure how the SD card contents will be affected when flashing ROMs, and I'm not sure if after you flash a new ROM, the ROM can use all of the stuff that's on your SD card just like the ROM you had before did

Again, all data/media remains but apps require A2SD or its variants.
Also, when I save a backup of my ROM, the backup will just be a copy of all of my phone's internal memory and the operating system, right?

When you backup/nandroid you take a screenshot of sorts of your system. By default I think most recovery images save the boot, system, data and cache partitions when a backup is being made. Certain recoveries offer to backup other partitions such as sd-ext (Where A2SD stores the apps). Backups are designated by folders with a time stamp, I personally rename these to reflect the contents e.g. MM.v.20 tells me this is MicroMods v.20 of his GB ROM. Obviously yours will differ but I find this keeps things organised. Basically think of nandroid as the Android equivalent of Acronis true image or Norton Ghost for the PC. It lets you create any number of backups which will restore your device to the exact state at the moment of backup.
And when I wipe my phone and install a new ROM, the new ROM just replaces all of my phone's old contents?

A newly flashed ROM will basically restore your device to factory settings but on the new ROM. Once you've signed in to your Google account certain settings and content will be automatically downloaded e.g. Calendar appointments, Contacts. Other settings will not be restored e.g. Display brightness, alarms.
So if I ever flashed my original ROM again, it'd bring back all of my phone's contents, system memory, operating system, apps installed on the phone, ect?

Nope, again it would return to the factory settings. However you can restore nandroid backups you have made of your original ROM which would return the system exactly to its previous state.
Basically if you're on a stock ROM it won't have A2SD. If you wish to use A2SD from now on then find a ROM which uses it, partition your SD card appropriately (Plenty of guides around) and you'll have minimal problems moving from ROM to ROM. As for Nandroid you'll find that most ROM devs recommend wiping all data from the phone (Not SD card) before flashing their ROM. Otherwise files or settings from other ROMs can cause some undesired effects on your current one.
Good luck and get reading the Nexus wiki, it's very helpful for these types of questions
Note: For some reason I vaguely remember someone noting that Froyos A2SD can be used to move apps to another ROM or at least the base app itself (If not the individual setup/settings) but I can't seem to find any info after a quick Google and it never interested me enough to look into it further. Perhaps someone can clear this up?

I dont think thats true.. suppose it's formatted during a wipe.. titanium backup serves the purpose like a charm.. (with all the settings for the apps and the resumes for the games)

I have a similar question to the OP. I use a 1GB EXT through DT's A2SD. If I wanted to flash a new ROM would the following be my step-checklist?
1 - Nand backup (just in case)
2 - Backup apps with Titanium
3 - wipe system data & cache
4 - flash new rom
5 - restore apps?
I'm just wondering what the procedure is to keep the apps in A2SD on a new flash without re-setting up.

yeah that would be fine..
btw 1: if you upgrading a cm nightly, you need not wipe system n cache..
2: if you do a titanium backup before, then you can finish all the steps in the recovery in one go..
n I dint quite get what you are asking. but from what I know, apps 2 sd folder (ie android.secure) is erased in a wipe.. that isnt changing
Sent from my Nexus One
shreyas - thanks for your help.
I understand the A2SD (EXT) partition onthe sd will be wiped, but I'm assuming I would have to do nothing to get the new rom to see the ext and use it?
That's really my question. Would recovering my apps from Titanium push them back on the A2SD location or would I need to install A2SD again?
i don't think so..
I suppose that the pro version must support the direct a2sd.. but give it a try.. if it dosent work then you have do manually..

I've been looking all morning, but nobody can seem to answer my questions. I apologize if this has already been covered, or if this is the wrong location.
I've got a Motorola Droid Bionic & I was able to get CyanogenMod 10.1 installed by following their instructions:
http : // wiki. cyanogenmod. org/w/Install_CM_for_targa[/url]
I am BLOWN AWAY by the speed and polish of this ROM and am looking to make it permanent. However, I have some questions:
1. I'm currently using it SafeStrapp'ed (custom rom slot 1). When I create the ROM area, it takes away the space from the internal SD card. What is that space used for? App installs? (Currently its only 1,2, or 3GB choices)
2. If I use SafeStrap to replace the stock ROM, will the SafeStrap restore be able to put everything back? My phone is running the 4.1.2 build.
3. Will I be able to use TitaniumBackup to restore the older Camera app to see if that will make it work?

1. Motorola had the great idea of taking the 16g of internal storage and dividing it in two; half for the opertating system, the other half formatted as a permanent SD card, and it functions as such. SafeStrap creates its slots in this internal SD card. When you connect your phone to the computer, you may have noticed that two drives/volumes are mounted. One is your external, one your internal SD card.
2. Not sure what you're asking. When you activate a different slot and flash a new rom to it, the phone is running off of that partition of the internal SD card. The stock rom is untouched. If you have different roms in different slots, the roms don't have anything to do with each other. If you're asking about wiping the stock rom, then you're looking for trouble.
3. I'm not sure if you can restore the old camera, but the new camera works wayyy better than the old one imho.

The camera works smoothly. More attractive than the stock camera, but the pictures are very grainy. And I've heard there are issues with video. I'm looking for the same solution on the same phone. Its a very nice ROM, except for the camera. I also like how well gsm functionality has been entergrated into settings. Makes it finally feel like the world phone it was built (not hacked) to be.
THANK YOU IN ADVANCE FOR ANY HELP! I'm dead new with android and just got a Nook HD+ 32gb (groupon deal $130)
anyway, I've done a ton of reading on here and watched a bunch of youtube vids- i don't know if people use overlapping terminology that means the same things or what.. and also seems like theres a lot of opinions in the forums.
I want basically the full android experience and root access- like i said, never used any android, but i like toying around with these things. BUT i also really want a fully stable platform- don't want constant crashing or it reseting on me.
questions i have-
1)the CWM is the "program" (don't know the correct terminology) that basically gives me the access to back up and install new roms, root, etc? TWRP does the same thing- but i understand you don't use that?
2)If i have a BRAND NEW nook HD+ do i need to back it up before messing with it OR are the "stock rom" zips you provided just that?
2) with the SD card image, do i need to put a specific image on the specified sd card. i.e. 4gb SD gets a 4gb image? or is the image universal to whatever size SD card i get?
2a) What problems am i going to run into using my mac to make the SD card, if any? what program do i need to use?
4) when you back up through CWM where does it save it? to the SD card?
4a) this is where i was confused about the image, reading into some of the posts it led me to think the image file took up the entirety of the
SD card.
4b)So in the future i could just boot from the SD card and would have the option to flash the stock rom back on the HD+ if desired? and/or
go back to CM?
5) what is DUALBOOTING? and NANDROID? how do they tie into CWM and CM10. very confused about this.
6) any disadvantage to flashing the EMMC vs booting from SD card every time? I THINK i want to flash the emmc, i don't want to be tied to booting from the SD card everytime- if I'm understanding that correctly.
7)what is this "trim" lag problem? couldn't really figure out what people were talking about.
thanks a ton for any help you can give me- I'm sure you receive a lot of questions!

CWM (ClockworkMod) is a recovery program that allows you to do just what you said. TWRP is also a recovery, but uses the touch screen instead of hardware keys to control it.

You can either use the CWM backup tool to return your device to stock (including any data you have already created, like registration) or the plain stock zips I have will also return you to stock, but the way it was when you got it new before registering.
3) with the SD card image, do i need to put a specific image on the specified sd card. i.e. 4gb SD gets a 4gb image? or is the image universal to whatever size SD card i get?

Since you have a Mac, the best way to do it is the new procedure without burning an image. Since I don't have a Mac, I don't know the exact programs to use. I think SDFormatter comes in a Mac version. And I know there are lots of mac partitioning programs to set the first partition active. And using the procedure does use all of the SD, so it is best to use a relatively small one, 2-4GB.

It saves it either to the SD card or internal memory, you choose.
Yes it uses all of the SD if you use the new procedure. But you need that if you choose to backup to SD. A backup takes about 1.5GB.
And yes, save the SD for future use, like restoring backups or installing new ROMs.
5) what is DUALBOOTING? and NANDROID? how do they tie into CWM and CM10. very confused about this.

Dual booting means having one operating system on internal memory (also called emmc for Embedded MultiMedia Card) and one installed to a bootable SD. Most people that dual boot have stock on internal and CM on SD. They are separate and independent from each other.
Nandroid just means internal memory. So a nandroid backup means backing up whatever you have on internal memory.
6) any disadvantage to flashing the EMMC vs booting from SD card every time? I THINK i want to flash the emmc, i don't want to be tied to booting from the SD card everytime- if I'm understanding that correctly.

The only advantage to booting to CM on SD is it leaves internal memory untouched for warranty reasons. The disadvantage is it runs slower and is less stable.
7)what is this "trim" lag problem? couldn't really figure out what people were talking about.
Click to expand...
Click to collapse
LAG is a complex issue to explain. If you are used to hard drives getting fragmented and slowing down your system, LAG is similar but a different mechanism with solid state flash drives. TRIM is a process to undo what causes LAG. But some of the solid state chips in these devices have a bug and when TRIM is run, it bricks the chip, making it unusable.

THANK YOU.. so much answered for me
I have a rooted Moto Bionic, and I wanted to load one more mod before I upgrade. I was following a guide using SafeStrap, and must have messed up. I had issues setting the Rom Slot, and am sure I wiped my phone clean. I can not boot past SafeStrap and can not load a ROM because it gives me an error saying that it cannot mount. I am stuck..... can you help me get this phone booting? I dont care if I have to go back to factory, I just need this to boot!
Which slot are you using? Stock? Rom Slot 1? And which one did you wipe?
The general idea is you leave the "stock" slot alone, and play only with the slots. So, what exactly *did* you do?

I fear that when I couldnt create (I thought I had) the Rom Slot 1, I wiped the stock rom slot. Now I am stuck, I cannot get a rom slot to create, and I have no stock rom. The kicker is I am trying different ways to flash back to stock and I cannot get into recovery. My down volume button failed a while back. Is there another way to get into recovery??
If you can boot into safestrap there is still hope. We just have to figure out a way to get a flashable ROM file for you to flash. Seems the most painless way is to put it on the MicroSD card... if you have a SD card reader and a microSD to SD adapter (or MIcroSD card reader) for PC.
If you don't, we may have a problem, esp. if you also lost the volume buttons.
Do you actually have a sd card in

Ok, I have it booted to safestrap, created rom slot 4 successfully, and when I try to flash from a zipped file it fails to mount (/system, /osh, & /systemorig). Am I flashing the wrong type of file?
This gets confusing, as my experience may not match yours.
1) Stick to slot 1 (or 2)
2) If you already have stuff in 1 or 2, back them up to sdcard-ext then wipe them (you can restore them later)
3) Do you have ANY prior backups? Try restoring that to stock slot first, if you really did wipe out stock slot.
4) TWRP/Safestrap won't let you flash the wrong type of file. Your trouble may run deeper. One possibility is the internal 8GB sdcard is slow to mount or flaky and thus can't be booted from. Though that'd be quite hard to test?

2) the slots are empty
3) my backup was wiped

I appreciate your help, and any other ideas that you may have. Is there a way to do it via PC connection, etc?

Hello tony.
fxz at this point may not be an option. although wiping all partitions and starting fresh may fail because you must remove safestrap first.Not sure why but I seemed to have read this elsewhere.
Also, do not do what I did and try to intall twrp instead of safestrap on 4.1.2 . that will require fxz for sure.
what zip have you been trying to install in the stock slot? this? http://forum.xda-developers.com/showthread.php?t=2240725

I just installed FireKat Rom and my internal storage is already full how is this possible? tried to install a app and it says it cant cuz its full what gives?
in the storage settings it says 506mb available space but when i plug in in my computer it shows 16.4gb available anyone know whats up and a fix for this?
anyone else having this issue?
ive already tried clearing the dalv and cache but still have the same issue.
do i need to make rom slot 1 bigger in Safestrap?
do i use stock slot instead in Safestrap?
currently searching on the net for a fix so far nothing, is this a known issue?
If anyone can help ill be sure to give a thanks and id be forever in your debt TY in advance
i had the same issue what i did was make a nandroid then use another custom slot and made the memory storage larger .. then recovered the nandroid to that slot and problem solved.. i kind of realized that because it has a multi boot thing every time you set up a slot you are basically making the full operation memory and storage while reserving space for more custom slots... once i recovered my nandroid to the larger customer slot i deleted the old one and i have been fine. inever used nandroid before then so i was very happy at how everything returned to normal without losses. i find it always curious that no one really answers this type of question.
so
nandroid back up if you have already set up and got things going
setup custom rom slot 2 adjust the sizes and activate that slot
recover the nan droid to that slot
then you can delete rom slot 1 that doesnt have enough space once you feel as if the poblem has been solved
