a stupid question from a stupid person - Hero, G2 Touch Android Development

hi all
i currently have modaco's 3.0 rom installed; i did this before i started using the phone so didn't have the issue i have now.
i want to change the rom (looking at modaco's latest actually), but im concerned i'll lose all my texts, emails, programs etc. the way it sounds in other threads is i will not lose them but having been a WM user for the past 4 years, I thinking, if i changed rom in WM and it deleted everything, why not Android?
so basically put; if i go from 3.0 to 3.* will i lose everything?
thanks for all the help!

I guess if you don't wipe before upgrading in the recovery mode, you will not lose anything.

You won't lose your data (unless you wipe before but why would you, really?), the upgrade will only replace the system files and leave your data unharmed. Big plus over WM
If you feel insecure you can always do a nandroid backup in recovery and revert to it IF you lose your data.

Hi there having been a windows mobile user myself, i had all these same questions as you. Android stores its system files in a different partition on the chip inside called system partition, and other data like programs, contacts, sms etc are stored in another partition called data partition. hence if u upgrade from modaco 3.0 to 3.1 or 3.2 without wiping(factory resetting) ur device while in recovery mode it can safely be done without having to lose your data. However if u decide to move from an android 1.5 to a 2.0 or 2.1 a wipe becomes necessary hence u will lose data. I recommend using titanium backup to backup ur important data before changing ur roms, it similar to PIM backup that we used in windows.

thanks to all who replied; hit the switch and its done. everything went perfectly

Backup the whole bits of data in the pda

Hi guys, there are so many roms created for the TD, Hail the chefs !!! and I would like to try some of them !
the problem is, my TD has gone productive for some months and if I flash another rom but I don't like it and want to go back to the latest state I need to do again the whole hassle (mitty or flash stock, flashing the good old rom, automated installation of programs, do settings, sync the data, restore messages from backup, and so on so forth...). for me this process will take at least 5 hours
i am just wondering if there is a tool to backup all data (rom, phone settings, installed programs, settings of all programs installed, pim, internal storage) in the phone. basically, the whole bits of data in the pda.
I believe with the existence of this tool there are many more people would like to try the new roms and find their best suited one

Quick backup question from a converted windows mobile guy

I've searched for this and cant find the info I need so be easy on me, i'm new to android but loving it. On windows mobile when you backed up your device and then did a firmware upgrade you couldnt just do a restore because of the changed registry settings and other issues that went along with it, you had to restore the software 1 at a time all over again. On the evo I have backed up with Titanium backup and mybackuppro. When froyo comes out (or any other upgrade) , will these backup softwares restore your phone to the way it was before without your phone being all screwed up, or do you have the same issues as windows mobile, and also does it matter if the phone is rooted or not, on how the restore process works? Thanks for any help in advance
Those programs back stuff up like bookmarks, user dictionary and home screen setup just fine and restore things like that very well. System settings and such tend to not backup well. Most applications will also backup and restore just fine although some paid / protected apps may need to be downloaded again but for the most part they restore just fine.
Nandroid does a complete and full backup of everything for complete restores should something you flash not be too you liking. Once you finish all the root / recovery steps that option will be in your recovery menu (phone off, power on while holding down volume, select recovery).
Both have their uses. Nandroid takes you back in time to a different rom or kernel or whatever while a program like mybackup pro make it less painful to get all your stuff back if you want to try out another rom.
It should be noted that a Nandroid restore is only supposed to work on the same OS version that it was backed up on.

What?
Nandroid works regardless of what rom you had before or what you recently flashed. You can have fresh or damage control, nandroid and try froyo and go right back to the sense rom regardless if its a 2.1 or 2.2.
You can set up three plus different roms and use a new one each day. There is no limitation of using froyo (2.2) and going to a 2.1 rom like damage or an asop rom if we ever get one.
Just wipe cache and dalvik before running the nandroid or flashing a new rom that isn't a direct decedent (fresh .2 to .3)

Ok, but you can't go back to say 1.5. So there is a point at which too much change in the OS will cause issues with the restore. I agree that within a few minor version points it is fine but I wanted to be conservative in my answer.
Ok , I think I have a good grip on it now. When I upgrade to froyo I will have to use Titanium or mybackuppro to restore my apps(one by one, or batch method) and maybe some of my settings, I can then use my nandroid backup if I dont want froyo anymore and want to go back to my old stock 2.1 sprint rom and have an identical image to restore, is this correct? Thanks for all the help.

How to flash ROM and keep settings?

Hello, I havent posted much here but I have been a long time reader. I am running CM6 on my EVO and have been for a few months now. I normally do not care about 4G but I am going to Chicago this weekend and want to be able to use it so here is my dilemma. I want to flash a new ROM but save everything (I can use NAND normally but this re-flashes my ROM too obviously) but I want to save everything (emails, texts, screens, apps; everything) but use it all on a new ROM. I have a feeling there is a way to do this I just dont know how. Could someone please point me in the right directions? Thanks!
You can use Titanium for your apps and texts and home screen settings. You will have to use the same launcher when you flash the new ROM in order to backup the homescreen settings. You are going from AOSP to sense so you need to really limit the system data that you backup/restore to prevent problems from arising.
Personally, I would just do a nandroid before you go, then flash the new ROM and only the stuff you need to get you through your trip and then restore your nandroid when you get home.

Titanium Backup Pro, Backup all apps and data. Make a update zip flash your new ROM, then reboot into recovery and flash update zip, then run Titanium backup and do a restore, then reboot phone and you should be good to go.
there is a way to do it but you may run in to problems with the new rom you flash. By not wiping the data before a flash just wiping cache and dalvik you can keep all of that but flashing another rom over an old one without wiping can cause problems like broken apps and fc's at random times for no reason especially sense. If you want to keep your contacts export them to your sd card messeges i'm not sure but apps you can save with titanium back up just not the data for the apps (it tends to lock up the phone). You can try it out and see how well it goes for you but i wouldn't suggest it, then again there have been some people who do this and have nothing wrong its 50/50 all up to you if its worth the risk just make sure you nand backup before you do anything

Flashing a ROM that's already been flashed on your phone

Title pretty much says it all but i have a question..Let's say i was to flash a ROM onto my phone that i had already flashed before but then decided to flash a different one but i also kept the .ZIP file on my phone. If i was to flash back to that old ROM would i keep certain things like the WIFI codes and the wallpaper i had before i went to a new ROM?Because this seems to be a problem for me. Also Would this problem be fixed if i downloaded a fresh ROM copy from the internet or off my Laptop?

Flashing the exact same ROM over your current ROM will tend to cause no issues, but no guarantee. Flashing to a different ROM, now thast a whole new can of worms. Its HIGHLY ADVISED to wipe all data and cache then flash. Use TDJ superwipe in CWM to do this, or you can use TWRP and do a factory reset. Now, depending on the ROM, you either flash gapps, or sign in into google. Either way, you have to sign in. If you would to chose to google to back up your phone, which is the default settings, then your wifi and wallpaper will be restored. You might have to restart to get the wallpaper back. Having the ZIP on your phone makes no difference in the way the ROM installs. The zip is no different then any other piece of data on your phone. You can find all the resources ive mentioned the development thread.

P.S Don't be afraid to wipe all your system data. It won't touch your SD card. Your pics and files will be safe. Only your ROM and programs with its data will be deleted. Use titanium backup or ROM toolbox to back up your data. SMS backup is a good program to backup your SMS.

Strictly answering your specific question... "If i was to flash back to that old ROM (ed: after flashing a different one) would i keep certain things like the WIFI codes and wallpaper i had before i went to a new ROM?"
Simple answer: NO. When you flash a ROM, generally whatever was on the phone will be lost. Generally, it's like installing a new copy of Windows on a hard drive that has been partitioned into more than one partition. Whatever was in the partition the new Windows was installed to will be overwritten (<< note key word). Stuff that got overwritten will be lost. Stuff that doesn't MAY still be accessible assuming you didn't format the partition first. While stuff that is in the other partition will likely still be there, but may not be useable due to various reasons. In the PC example: installing Windows on a formerly Linux pc and retain the other linux partitions. The data's still there, but Windows (without massive driver/software support) will not be able to read the other partition and will ask you to format before using, which WILL then destroy all data there.
Stuff like wallpaper, it depends. If it's a wallpaper that was a file saved on your SD card or one of the stock wallpaper that came with the ROM, you can reuse it, however, you WILL need to reselect it (unless the stock wallpaper was the default one, which sounds like it was not, in your case).
Stuff like WiFi codes, all bets are off, and I wouldn't put any $ down as chances are VERY good that that information will have been erased. That's why you are supposed to keep backup of that information, preferably in a location away from the device.
Only data stored on the SD card and whatever partition that was not specifically erased/overwritten by the installation process will remain, and if you follow generally good practices, you should have had erased the various partitions and caches on top of the installation to ensure maximum reliability of the ROM. Thus only what you have on the SD is the only thing that would be retained after a ROM installation.

I agree, I too use Titanium. If you're really concerned about saving data (like that WiFi codes), then you will need something like Titanium and a SD card. Just remember to restore that data.
Please be aware that this assumes that you are using the saved data from the original ROM and, after trying a different ROM, you are going back to the first one.
If you are trying to migrate data (like the WiFi Code), for example, from the second ROM to the first ROM, this will only work IF both ROMs used the same software to handle WiFi and data are stored/used the same way in both ROMs.
That's why it's a good idea to keep a hard copy of the account and password information backed up separately from the application that's using the information. At the very least, in a text file stored on the SD card. I prefer using Dropbox and store it OFF the phone itself.

Sense crashing, data trapped

Today I tried updating my ARHD from 31.2 to 33.1. Before and during the process I made few beginner's mistakes:
- didn't back up important data
- didn't do ful wipe (it is not mandatory :silly
After reboot I got constant Sense crashes, and I practically can't use HOX as a smart phone (calls and messages are still usable :good. I am aware that most probably I will have to do the full wipe to make my phone woking properly.
What I am looking for is a way out of this situation, with keeping the most important data. Basically, I need data from few apps only (SMSes mostly, and some notes that were note backed up).
I was thinking of making a nandroid and extracting them out of there. Might be dirty, but I do need this data.
Where these could be located? How coulld I access them? Is there a way that I can access this data through CWM?
Every advise that will help is appreciated
I made a CWM bakup, and in a data partition, I found a file "hc_sms.db" in data\data\com.handcent.nextsms\databases\ that is some 200+k.
Is this what I am looking for?
Problem solved, thanks to wajahebat.
Data from cwm backup was ok, system was not. So, after full wipe I restored data only, and now my phone is working fine.
