Does one need to wipe all their data if they were to flash a custom ROM for the first time on their phone? Can just wiping the dalvik cache be enough?
Your input will be much appreciated

Always safer to wipe it all. That keeps ghost errors from popping up.
Always wipe all m8 cause u can experience lot of problems like me when I flash new kernel and didn't do wipe and I have problems with battery measure after wipe it was good.
Its always a cleaner and faster Tom to wipe all and it gives u a chance to test the rom alone and report back on bugs if any.

You can use Titanium backup or something similar to backup the apps & data. That way setting it back up after wiping isn't as difficult/time consuming.
Just don't restore system data & I personally like restoring each app individually.
As far as it concerns backup apps : I prefer backing up the preferences of the most complex apps from inside the app on sd card instead of using titanium or others. In my case, this is only necessary for about 5 apps. The rest has no special or complex individual preferences. The reason : restoring apps completely via titanium or others may cause problems. Recently I had a bug after restoring go launcher with "my backup root". Only a fresh installation helped.
For reinstalling the apps themselves I find it pretty easy to go to my apps library in the market on the PC and reinstall them using the service that sends them directly to the phone.
All in all I deem it cleaner not to restore apps!

Is it posible to flash with data loss?
Or can i backup my apps data and then restore it when i flash to another Rom?
It's not possible to flash a ROM on top of a previous ROM w/o expecting any trouble. Either you get bootloops, hangs, or all sorts of force closes with apps. Backup apps w/ Titanium Backup. TB will save the apps and data to a folder on the SD card, from which it will restore the apps when you click "Batch Restore" after flashing a new ROM.
thanks for the advise gonna do it tonight

I've flashed about 100 CM7 nightly builds and release candidates on top of each other without losing data so that isn't strictly true! ROMs made by different chefs that are significantly different from each will need a data wipe though, and TB is useful to some in that situation.
Well i want to go from LeoMar75 Rom Revolution 2.1 to 2.2
I use rom manager and have sometimes updated my rom without wipping my data, but it's not always stabel.
I would recommend first making a backup of you data with titinium backup or mybackup and then updating your om

Sorry, I should've been more clear that when switching from one ROM to an entirely different one, you should wipe. But then again, even with ROMs that are of the same series, sometimes the differences are so great that it's best to wipe clean before flashing. I'm speaking from my experience with StarBurst.
Hey, so this could be a completely stupid question, but what is the 'correct' way to upgrade a ROM? At the moment I reboot into Recovery and then select 'Install .zip from SD card' and just pick the new ROM.
However, in the thread, people are saying to use a command or something? I used an all-in-one tool to remove the bootloader/root my phone (International One X) so I don't know if that command is for people rooting it via Command Prompt or what have you.
I have no idea which way is better, so I thought I'd ask here to make sure I'm not doing anything wrong.

Your method should be fine. You do need to check with the developer though as some updates require a full wipe first in order to prevent any bugs. Use titanium backup or some similar backup program so you can easily restore your apps and settings after a full wipe.

Ah ok, thanks for clearing it up!
i wasn't sure on that one either, so now i know it's nothing wrong with installing from sd card. i have one question still, where can i find sony ericssons firmware, something like http://www.sammobile.com/firmware/ for samsung.
You can have some stability issues if you don't do a full wipe
I always full wipe and clear cache and dalvik cache before and after install. Overkill probably but never had a problem.
I'd do a full wipe every time but recently the ROM I'm using has been putting out updates every few days, restoring with Titanium each time is such a hassle, definite first world problem.
Your way should work but sometimes when i update without a full wipe some programs FC(force close) and i lags.
I use 4ext for recovery. It has a script that will format and wipe everything that needs to be wiped (except the SD card) then I use Titanium Backup. I bought the pro version which is less of a hassle when restoring.
-place newer rom on your sd card
-backup current rom just incase you need to go back
-use titanium backup to save your apps and app data
-wipe everything, then do it again just to make sure
-install your newer rom
-enjoy
I know this seems like a hassle everytime to update a rom but I usually flash roms 2-3 times a week and I have never had a problem with a rom that wasnt developer related. Hope this helps
Hey everyone-just wondering what your preferred regimen for backups/restores is when using tibu. I backup all modified data for my apps nightly, but I don't really play with user data for the sake of conflicts when flashing between ROMs. Can anyone provide me with some insight as to how to keep as much system data as possible between ROM flashes(ie my email accounts, WiFi access points, some system settings, etc) that arent likely to conflict with other ROMs (so long as they're on the same version of Android)?
Just wondering if there's an optimal backup/restore regimen I'm unaware of.
Thanks guys!

Subscribed! Same questions have been running through my head.
System data will potentially corrupt your system, from one base (ROM) to the other. Wiping data is necessary to prevent bugs and glitches.
If you are flashing an update to an already installed ROM, you can forgo the data wipe (factory reset), and wipe only: cache, dalvik, and system. This will keep your data intact.
Doing a factory reset on occasion after several flashes, will clean up some potential problems.
Wiping SD card, internal and external, will also help with any potential problems. If wiping SD card you should only have to save media (pix, music, video) and any docs to your PC. Then format card, then add back your media and docs. You should notice better performance.
Wiping data can be necessary, a part of flashing ROMs. As far as TiBu I backup everything. When restoring you have the option to restore data or not. If you are restoring from a different ROM choose to only restore app.

Well I appreciate the reply, but this is all stuff I'm aware of. However if what you're saying is that nobody out there really bothers with restoring any system data from one base to another, then that answers my question and what I'm already doing is the best way to go.
Thanks.

No one restores system data unless they want problems.

Exporting sms and call log is the only thing I've ever need. I was extremely happy the day they added that.
I don't even backup app data anymore. Except for 2 authenticators I use. I prefer to keep as much stuff on cloud storage as possible. I trust my SR and ROM, I just don't trust myself.

I flashed CleanRom 5.0 the other day, along with the new Modem and RPM. I was previously stock and rooted ICS. I no longer have the ability to use DLNA, and searching the CleanRom thread in the Developement section it looks like it might be because I did not install the Allshare app when installing the ROM.
http://forum.xda-developers.com/showpost.php?p=30877701&postcount=1131
I want to go through the install again, but have a few questions, but don't have the authority to post in the ROM thread. Just want to make sure I go through the right steps.
Do I just need to boot into CWM recovery and do a system wipe, cache wipe and delvik cache wipe, then reflash and install the ROM with the options I want?
Do I need to reflash the Modem and RPM?
Also, in this post, http://forum.xda-developers.com/showpost.php?p=34675681&postcount=7511
Scott states at the bottom "3. Restoring data form ICS is highly discouraged but I dont th ink would cause any screen jitters."
Does this mean that I should not restore my User Apps & Data that were backed up using Titanium Backup Pro from my original ICS ROM? I can re-download my apps from the Playstore, but it really easy to do with Titanium BU. I restored my User Apps & Data this way after originally flashing CleanRom 5.0, and didn't notice any issues, but want to make sure I do things the right way this time. I did not restore any system apps & data, just user apps & data.
Any help/input would be greatly appreciated. Thanks for helping a rookie out!
Boot into CWM, wipe data then flash the ROM the way you want. You don't have to flash RPM or Modem again. Just restore your apps and their data. Don't restore any system data (never should).
This what you needed?
Yes, that is perfect, and what I thought. Just wanted to make sure. Thanks!
I do have a few other questions that I would like to have answered:
With the CleanRom installed, am I going to get prompted for the Verizon OTA updates when they get pushed out? I assume not.
Not saying I want to go back to my stock/rooted ICS which I made a nandroid of, but if I did decide to restore that nandroid, it restores the Modem and RPM that go with that ROM, correct? Or will I need to find and flash these?
Thanks
The OTA is disabled in CleanROM. Nandroid backup should copy everythng.
Got another question regarding data wiping.
In section 2 of this thread: http://forum.xda-developers.com/showthread.php?t=1762709
states "Step 5: Wipe Data/Factory reset, then under the "mounts & storage" menu Format System."
In all the threads I have read I see folks state to do a data wipe/factory reset, wipe cache, and wipe dalvik cache. I have only seen the "Format System" in this thread.
The reason I ask, I just went through the process of re-flashing CleanRom 5.0 and did the data wipe/factory reset, wipe cache, and wipe dalvik cache and when I go into my file explorer, I see folders from before doing a data wipe.
I assumed a "data wipe/factory reset" would delete all this info from the internal sd card bringing it to a clean factory setting. Looking at the "Mount and Storage Menu" in CWM, there is the option "format /system", "format /sdcard" among others.
I guess I would like to know if a "format /system" is required, and would this get rid of old data, or is a "format /sdcard" the right thing to do?
Formatting system is a matter of preference to be honest. You don't realize this but by flashing CleanRom 5, Scrosler (that roms dev) has the rom automatically format /system before it installs. You'll notice it does so if you watch and read it as its installing although it does say this in passing. So to answer your question, it already formatted /system as it installed BUT this isn't the case with every rom.
When you "wipe data" and flash a rom, all you're deleting is the software on the phone itself not the data saved to your internal or external sd card UNLESS you manually select "format sd card" in the process. All your photos/movies/etc are untouched otherwise it would delete all this data and therefore you would not be able to flash anything because your internal storage was already wiped/empty. Make sense?

The best way to backup your apps is by using Titanium Backup. It'll backup all of your apps and their data, you need the pro version to backup call logs and messages but it's well worth it because the pro version also allows batch restore (without batch restore you need to individually press ok for each app that you're restoring). Titanium is by far the most important root app that's available. You don't need to backup your personal data (music, photos) on your internal storage because you don't wipe the internal storage when flashing a ROM.
When flashing a new ROM you need to perform what's called a full wipe, this is wiping system, data, cache, and dalvik cache. Using TWRP recovery (the best recovery) you enter the wipe menu from the main menu, then select advanced wipe, and then you can select the previously mentioned partitions to wipe. This does not wipe your internal storage (the user-accessible virtual sd card where all of your personal data resides), wiping the internal storage is never necessary when flashing a ROM.
If you're just updating the same ROM (flashing a newer version/build) you don't need to worry about wiping, you can just flash the zip and reboot. Only ever do this when updating the ROM you're currently using though, never when flashing a different ROM.
