Im using LeeDroid 3.3.1 on my Inspire 4G right now and I see there is an update to 3.3.3
I installed the first rom using Rom Manager a couple months back.
This is going to be my first time doing an update to a Rom.
Are there any special tips?
Will it wipe my data and apps?
Is it better to install it with Rom Manager or some other way?
Thanks for any advise.
After it downloads the update you'll get a pop-up with three check boxes:
Back-up existing ROM
Wipe Data&Cache
Wipe Dalvik
Wiping just dalvik and backing up is what i usually do with updates, it keeps all of your data. Wiping Data&Cache is for doing a clean install without data being saved.
Backup & wipe Dalvik.
Got it..
I'll give it a shot.
update wont wipe ur data unless u wipe manually. some update do require a data wipe if there's change related to system component, so if the update fails, u may need a wipe.

Well. Glad I did the backup.
That didn't go so well.
I was missing quite a few apps, even rom manager was missing.
I'll try again.

i'm using a htc desire running on cm6.
when there are newer versions of cm and i would like to update to it.
what is the best way of achieving this without having to wipe the data/settings/etc?
if there is no such way, what can i do to backup settings/data/apps so that once i update to a newer cm , i can just restore my stuff?
what about Rom Manager Premium, theres an option to check for rom updates, would Rom Manager update your rom for you?(and keep all settings/data/etc?)
Yup.
it does everyting. buy it. seriously.

seriously?
i use titanium backup and it works fine for me..
another option to back up your apps & system data is the nandroid backup on the recovery menu..
titanium backup requires busybox and for that to work i need to be nand unlocked.(which im not).
i always thought that nandroid backup will backup everythign to a state, so if i were to upgrade roms, and then use restore, wont it just revert me back to the previous state(not updated)?

You are correct. A nandroid restore will undo your update.
If you're upgrading to a newer release of CM6, you should be able to do it without wiping your data. Wipe dalvik and cache, flash the rom, and reboot. You'll have new featuers but all your old apps and data in tact.
Nandroid backup first for good measure though
oh okay, so wiping dalvik and cache would just wipe all settings(including home screen layout, widget placements, folders etc?)
some tutorials that i've read about updating roms, is that i dont even need to wipe dalvik and cache, anythign bad about that?

Nope, dalvik and cache wouldn't even affect your settings.
The cache is the temporary cache used by the Android operating system, and the Dalvik-cache is the cache used by the Dalvik Virtual Machine. The only thing about wiping them is that the first boot will take longer as they rebuild their indexes and such.
Nine times out of ten, you'll be fine without wiping these. It's just generally considered "better" if you do.
Again, nandroid backup and try it out. If it doesn't work without wiping, restore back and wipe the caches.
I made a backup of my system in xRecovery earlier.
If I want to restore that backup, do I need to wipe anything?? Like cache?
Or do I only need to restore and just reboot?

the better thing that you can do its full wipe (factory reset, wipe data cache & dalvik)
when you flashed the backup do battery wipe...
full wipe its better because the apk´s need to zipalign again, do a new busybox, etcc...

Hello,
I've been using xRecovery for a while on my Xperia X8. I usually make a weekly backup and if the phone crashes then I restore completely the latest backup. This implies in restoring apps and data to the previous state as well.
Today I was taking a closer look at the "partial" recovery options of xRecovery, and saw that I can restore only the system.
Initially, I thought I had found the solution, as I would be able to restore only the system, and maintain the state of my apps and data.
However, your response above has confused me a bit.
So, if my Android's system crashes, I can't simply restore only the system, and keep the current app and data? What would then be the best way to restore the system and have the most recent data and apps?
Thank you,
M!©k3t$

Do you have to backup to stock rom or can you just install a rom on top on another without backing or w/e?

You should backup your rom before flashing, this way if anything goes wrong you can go back.
You should always wipe, wipe, wipe.
Wipe data/factory reset
Wipe cache partition
Go to Advanced and wipe Dalvik Cache
After the wipe go back and Install zip from sdcard. After install I do another wipe on the Dalvik Cache then fix permissions. Remember Wipe, Wipe, Wipe.
so as long as I do that then I can install a rom over another and delete the previous one while doing so?

I recommend making several backups.
First, make sure you have Clockworkmod installed via nvflash. Then make a backup. Download the backup to your pc for safe keeping (just in case things go wrong).
Use Titanium Backup (free version works, but buy the full one if you like it). Use the batch feature to back up all user apps. Do not back up system apps.
When installing a new rom, especially roms that use different versions of android, you should wipe everything you can except the external sd card (where you keep your backups). Wiping "system" is important.

....to wipe unneeded files in the dalvik cache, and so they will add up over time and take a lot of space and make the phone slower? Therefore it is a MUST to root one's phone?
Is that a correct assumption?
Thanks!
Try it. Use any file manager, go to /cache/dalvik-cache, and delete something, or everything.
The reason why it is called a cache is to speed up the phone.
It won't take up memory because of the way the phones storage is partitioned.

For formating caches you could use file manager but it also need root permission...
And until you flash other custom rom you need not to wipe cache...
Apps cache is being created for the first time you boot your phone for better application launch...
So if you got a serious problem of force crash on stock rom, please do full reset...

You can use Factory Reset from Settings menu.
guys...
Guys, please read the original post.
Anyway, I tried unrooting my phone and deleting contents of dalvik cache. As expected, this is what happened:
1. Using ES File Explorer, WAS NOT ABLE to access the /data/dalvik-cache folder. It showed "Empty folder" or something like that.
2. Using Root Explorer, message that read "You're phone doesn't seem to be rooted, etc. etc. " (cannot access folder also)
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
So here's my new set of questions:
1. Does factory reset erase dalvik-cache? (I would assume so)
2. If phone is unrooted, dalvik cache contents cannot be accessed or deleted (as I have proven). Does that mean they will add up over time (unless you factory reset the phone??) and cause problems like making the phone slower?
Hope that's clear.
Thanks!!!
What phone are you using? If for samsung, you can still wipe that in stock recovery even if you are unrooted...
Dalvik cache is in your /data partition, so yeah, it will be erased if you factory reset...your phone should manage dalvik by itself, it should not build up (except if you mess with it), so don't worry...
Ryuinferno, hello. I'm using Samsung Galaxy Ace. So how do I wipe the dalvik cache in stock recovery of unrooted phone? Are you referring to factory reset / data wipe? I know that already. I know that already. If you're referring to something else, please let me know.
Are you sure android phones manage the dalvik cache by themselves? Because sometimes when I uninstall an app, a related file would still be left in dalvik. I would then manually delete it or delete it using Titanium Backup. Also, why does Titanium Backup have an option to "Clean up the Dalvik cache..." if the phone manages it by itself?
Thanks!!!

Even wiping dalvik cache will cause apps to misbehave in you don't factory reset ...
If you are rooted , it will also have same effect ...
So do factory reset if you are in stock ROM and full wipe if you are on custom ROM ...

Hmm...I can't remember too well as I left stock recovery too long...never left my phone unrooted......I think there is a wipe cache option in stock recovery but I am not sure whether will it wipe dalvik or not...
Titanium backup has an option to wipe dalvik because when changing ROMs/restoring apps, the current dalvik may be conflicting with the newly restored app...that is why you need to rebuild them...usually the old unused dalvik should be cleared upon a reboot...
"Hmm...I can't remember too well as I left stock recovery too long...never left my phone unrooted......I think there is a wipe cache option in stock recovery but I am not sure whether will it wipe dalvik or not..."
Maybe not? Because wipe cache and wipe dalvik cache are two separate options in ClockworkMOD Recovery, is it not? Or maybe in stock recovery, it DOES wipe dalvik as well....
Hi.
I use a custom rom and I want to change to Purity. I want to make a real clean install, to clean every useless stuff on SD card.
I suppose I need to do a factory reset and wipe system partition.
But I prefer check here before.
Thank you.

Backup what you want to keep on the SD card, then run the factory image following the guide on here to the T. You'll then be 100% stock with a clean, stock ROM
Hi,
The rom has nothing to do with your sdcard (this part of the storage), I mean a clean install is with a full wipe: Wipe Data/Factory Reset and Wipe Cache Partition/Dalvik cache, no need to wipe the sdcard, but if you want....
