I'm just wondering, I am currently on r73 for SynergyROM.
Once ech releases r77+, can I just download r77 onto my sdcard, go into CWM and install?
What's the proper process? Do I have to do a complete wipe?
Or just wipe cache and dalvik and install?
It depends: I prefer to do a full wipe-- which includes wiping data + formatting system in cwm. Just clearing davlik/cache is also known as a dirty wipe, and has a potential of having problems later down the road if you keep flashing dirty. Yes, you can download the .zip file onto your sd card, make a nandroid backup (if you want), and then perform a dirty/clean wipe, then flash the ROM. Don't forget to back up user apps with TiBu!
If the base changes then you'll want to do a fresh install. I'm not sure what base eschelon is using at the moment since its been a while since i used synergy. But i'd assume hes updating to the latest base in which case you'll want to a fresh install.

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.
vision
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'm running CM7 and would like to try out the MIUI rom. Do I need to wipe data/factory reset in recovery before flashing the new rom? Also, is there anything I should do outside of a nandroid backup before flashing a new rom? This is my first time flashing a different rom.
In your case, yes.
Developers and their ROMs vary in the changes they make, and while some might need no wiping, many do.
As a result, as a general safe consensus, the following is usually recommended to avoid all possible repercussions.
1. factory reset
2. format/cache
3. format/system
4. wipe dalvik cache
Again, this isn't always necessary, but when moving from one ROM to another, this is a good idea.

Cool, man. Thanks for the quick reply! Was hoping I could avoid a data loss. Flashing now.
I've used Titanium Backup whenever I've switched roms, and it's been super handy.
You can usually safely just wipe the cache, format the system and wipe the Dalvik Cache and leave the data partition alone (as long as the rom is using the same file system type). Then on the first boot all your previously installed user apps will magically reappear, but your first boot will take much longer.
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.

Ok so I'm on AOKP build 40 (Rooted,Unlocked) If I wanted to go to another Rom, how do I go about doing it? Do I simply just download the new Rom files and flash over whatever Rom I'm on??

You will want to first back EVERYTHING up...your data, your apps through titanium backup or whatever backup app u wish to use.
Before booting into recovery, ensure the rom zip file to be flashed is downloaded and saved to a safe location.
Then boot into recovery and do a nandroid backup through the backup/restore menu. Once done, then wipe data/factory reset, wipe cache, wipe dalvik cache in recovery.
Then flash from zip file, and choose your new rom zip file and flash away.
You will probably want to look at the post for that specific rom you will be flishing in the dev section first before flashing Some roms have specific flashing instructions.
well with rom manager you could just flash it over but i only did that on my mytouch4g did for like 10 roms. but sense it a tablet i would do a clean install (delete everything)
Hello All,
I am new at this "flashing" scene and have a few questions. Could someone please tell me exactly what steps I need to take in order for me to put a newer "Nightly" CM 10.2 on my Verizon Galaxy S3? I hate the idea of having to re-download all my apps each time I get a new ROM. One of the questions I have is exactly what is "Dalvik Cache"?
Any help would be really appreciated.
Thanks,
Bruce
I'm not sure what recovery you have installed, but i use Cwm & I backup my ROM to external sdcard. Flash the new nightly & use advanced restore option & restore data only. Its always worked for me, I just wouldn't do it going in between touch wiz & AOSP

Hi & thanks for responding! I am using the latest release of CWM. What I'm still not clear on is what steps do I need to take to flash the new Nightly?
Thanks!

0 - make sure you've back up your IMEI.
1 - always do a nandroid backup
2- titanium backup (TiBu) to back up your apps
3- back up all your data (music, etc) onto your external SD card.
4 - going from TW to AOSP (or from one AOSP to a different one) always do a clean wipe: cache, dalvik, and factory reset.
Would not hurt to format your internal SD card either.
5 - after new ROM installation, can restore your apps with TiBu - restore apps and data. NEVER use restore system data option!!
.... Unfortunately there's no way to install a new build of ROM without having to reinstall your apps. TiBu makes it easier, but they still need to be re installed

Thank you for the info! I will give this a try once the next Nightly comes out.
I've always dirty flashed nightlies and have never had an issue.
With all due respect I would ignore everyone who has posted in this thread so far (except jbjarko's comment). Not sure if they misunderstood the question or if they just have a lot of extra time on their hands.
If you already have CM10.2 installed then all you have to do is download the newer nightly via the cmupdater app (System Settings / About Phone / CyanogenMod Updates) then after it is downloaded select it and click "update".
It's not a back idea to make a backup once in a while (i make a backup using Rom Manager about once a week), but 99.9% of the nightlies will flash just fine. AND if you ever do have a problem after flashing a new nightly just reboot into CWM recovery, wipe cache and dalvik cache, then re-flash the last working nightly.
The vast vast majority of the time you should never need to redownload a single app or reconfigure anything when going from one CM10.2 nightly to another CM10.2 nightly.
So in summary:
1. Use the built-in cmupdater to update from one nightly to the next
2. Always keep the last working nightly on your phone in case you need to flash back one version (cmupdater saves it on your internal sd card in a folder conveniently called "cmupdater")
3. Occasionally make a full backup (a nandroid) using CWM in case things really get jacked up
'Dalvik cache' can be cleared by going to "Advanced" when you are in CWM recovery
