As you all know, before installing new rom we we have to wipe data and cache in recovery...
But do we have also to wipe dalvik's cache?
As you read on every ROM thread, it is advisable to do a CLEAN wipe meaning all of it before installing a different rom. I personally don't find any difference between wiping and not wiping.
When upgrading CyanogenMOD nightlies wiping is pointless, and a waste of time. When switching between Sense-based ROMs and CM etc. then a full wipe is recommended, but not always needed. Wiping dalvik cache will never hurt
Just a thought here, but isn't DC in /data ? So if you wipe data you wipe DC as well, no?
I've been flashing Mdj Droid L2.1.110210 rom but the only thing I am seeing is the HTC screen for over 10 minutes. Is there anybody helps me to solve this issue? I am newbie so I cannot post in Mdj Droid L2.1.110210 topic.
Thank
I always wipe because it cleans the dust. As GrammarFreak said, when switching between CM nightlies, it is pointless as of the minor changes that come with them. But switching to an entirely new ROM (like stock -> CM) I thin it is better to wipe everything. The cause: Android DO collect junk, and a clean system is always nice.
Regarding contact, sms and other app data: backup to phone and cloud, simple as hell.
thanks for the advice. so if you flash anew rom, do u lose all ur apps every time? i'm flashing ics on my g2 alpha 8 right now. so i will find out soon enough

In my experience (using a HTC Desire HD) you only lose your apps and settings when you perform a full-wipe before flashing a new rom. When you update your rom without wiping, your settings and apps are not removed. However, I personally like to do a full-wipe before flashing a rom, because it clears out al the dust and gives you a fresh new phone.
If you don't want to lose your apps and data, but you do want to wipe, you can offcourse always use Titanium Backup to make a backup of the apps and data.
Just do it! It's free (costs only a slightly longer startup the first time after you wipe dalvik)!

in my experience, this happens when you dont clear the cache prior to updating the rom. in my case, I had to re-apx mine, since I didnt figure this out until I had tried the factory rom. good thing I had the SBK and CPUid, or it would have been even a more painful experience!
So I currently have Das BAMF 3.0 flashed onto my HTC Thunderbolt. It's working perfectly fine; but say I wasnt to flash another ROM, do I have to wipe my data and cache again via clockwork recovery? (yes I backed my phone up and backed up with titanium back up)
Yes or you will run into issues like me

When switching between ROMs from different devs one should always wipe data/cache. Different devs sometimes use different packages for some of the base system apps and the data usually won't "mesh". If you don't wipe, you may not notice a problem initially...but a few day's later you'll be asking "Why does XXXX force close on me?"
Only time you shouldn't have to worry about wiping is if you're flashing nightlies or incremental versions of a rom where not much has changed unless the dev states otherwise in the release post.
Like the title states, i would like to update my MIUI rom from 1.11.11 too the new Galnet version 1.11.9. How would i do this? Does it require me too completely wipe it and flash the new rom or could i just update my current MIUI version?
wipe 10char
You could take your chances, but it's safest to flash back to stock and then flash the new one.
I've gone back and forth between MIUI versions with no problem. I just install one on top of the other. I usually just wipe the cache and the dalvik cache, but don't do a complete wipe. No issues whatsoever and I've probably gone back and forth between versions 10 times.

Thank you, your experiences will help me greatly.
honestly there are alot of voice issues right now with phone calling on the newest Galnet.
I've had CM7 a3.5 on for a few days and set up my android install pretty much exactly how I want it however I'm looking to try the Xron flavor of the rom. I know the install instructions say you need a full wipe, but I've seen a lot of reports saying that flashing over it works as well.
Anyone have any experience with it?
I installed it with just a wipe cache/dalvik cache. I did the wipes twice. It's been great so far.
Read the posts though , some have had troubles. Make sure you have a backup!
Sure you "can" just install over but the true question is "should" you. If you just install over a3.5 you wouldn't see the same benefits as coming from a full wipe.
Hi,
Apologies if this thread is redundant, I kind of found what I was looking for scattered around here after reading til my eyes bled, but not quite the reassuring, specific answer I am after...
We have 2 Vibrants that we are looking to move to a Jelly Bean ROM from ICS Passion.
At this stage it looks like either Helly Bean or Slim Bean, people seem to be getting reasonable GPS service with these and our two phones seem to get good GPS lock on ICS, so here's hoping...
I am mainly interested in knowing if I should take any intermediate steps before flashing the JB ROM.
Both phones were taken out of the box, rooted, CWM'ed and flashed with ICS Passion when new, so I am not sure if that leaves the file system etc ready to be flashed with JB? Obviously they won't have Gingerbread bootloaders, which may or may not be important depending on what you read?
Both phones were flashed with the wipe data / wipe cache partition / wipe dalvic cache method. No format system or anything else.
If I use the same method to flash Helly Bean or Slim Bean from where we are at am I looking for trouble LOL? Or should I expect it to be smooth as silk?
Thanks in advance for any help..
You should be fine. GB boots aren't necessary so don't worry about that. You should wipe all the things you mentioned and do a system format, its in mounts and storage. When you flash it will take 3 flashes, you only need to wipe on the first.
So wipe, install ROM zip. It will not complete, pull battery then 3 button to recovery. Flash it again, this time it may or may not complete. If not, do battery pull etc, if it does complete, reboot recovery. Flash ROM zip again, then gapps zip and reboot. Allow 5-10 minutes then set device up and reboot again for safe measure.
***I wouldn't overlook Paranoid Android, its a great ROM. I prefer it to helly bean.***
I approve this message.
Awesome. Thanks heaps.
So, wiping in this order is correct?
Wipe data
Wipe cache partition
Wipe dalvic cache
System format
Or does the order not really matter?
Second question, does the system format clear everything out? Will I lose my current nandroid etc?
Also, when you say no need to wipe after the first flash, does that mean to do none of the 4 wipe operations?
Sorry to be so painful, just trying to remove as many variables as possible!

The wiping order isn't important. Formatting system doesn't mess with backups or anything other than /system. That's where the ROM apps and gapps are installed.
You are correct, after the first set of wipes it isn't necessary to wipe again. Basically the first two flashes setup the partition scheme and new kernel/recovery. The third installs the ROM completely.
Good luck!

Cool bananas. Thanks man...
Now just need to make a decision on which ROM to try first...

If you're willing to spend some time test driving JB roms, I would recommend this progression:
* CM10 Nightly ~ plain jane (but it's the heart & soul of it all).
* AOKP JB ~ ROM Control will set you free.
* Helly Bean ~ DerTeufel is a true Master Chef.
* Slim Bean ~ Slim, lean, & lightweight (my daily driver).
* Paranoid Android ~ Most who go PA ... stay PA.
I put PA last because that potentially requires the most time to investigate & discover all the possibilities. Tweaks galore and check out the GPS fix discussion in that thread.
Kernels:
* Semaphore ~ solid kernel, excellent rom performance, & Semaphore Manager available via Play Store.
* Devil ~ the only JB kernel with Voodoo Color. Very tweakable.
Enjoy.

Cool, thanks. Not sure how much time I'll get to play around and try out different ROMs, but I did put Slim Bean on one phone last night, so hopefully that has brought it up to a more contemporary file system and stuff so flashing from here won't have to have everything wiped and will be a bit of a quicker process?
Slim Bean seems nice, definitely smooth and fast, but being stripped down as it is I didn't get that awe-inspiring, new car smell that I could when first flashing ICS from Eclair :laugh:
I need to sort out a couple of things to keep using Slim Bean.
One is where to add alarm tones, it comes with two. One is way too subtle, I used that this morning and would have slept through it if the phone didn't vibrate its way onto my keys and start rattling them LOL...The second one is that stupid rooster that will wake my whole family, the neighbours family, and all the local wildlife.
I also need to find the download for the autumn leaves/water live wallpaper that was bundled in Passion, I miss that already... :laugh:
Battery life is good, between 11pm last night and 5am this morning it lost 2%

The only thing I had to do different from this was do 2 flashes in a row without powering down. Every flash after powering down just returned to the status 7 / incompatible partition error. 2 flashes back to back pushed past that and got the semaphore recovery up and going..
So I ended up doing;
Wipe data
Wipe cache partition
Wipe dalvic cache
Format System
Flash ROM
Power down
Flash ROM
Power down
Flash ROM
Flash ROM
Flash Google Apps
Boot
Cheers...
Lol, you shouldn't power down in between. Glad you got it up and running!

I may end up trying one of the other ROMs in the next day or so. Slim Bean is nice, but every time I go to use my phone for something I seem to need to install something else LOL... The stripped down nature of the whole thing is killing me...
What I meant is if it goes into a boot loop. My bad, I should have been more specific. Either way your there now. That's what matters!

Yeah, I think I will.
When I get a chance I'll read it's thread and see if anyone is having any problems with the current release and if not, I'll flash it.
Hopefully it's a bit more of a streamlined changeover now I am on a current kernel and recovery?
Yeah just a normal wipe/format system and flash. I'm running it without issue, and GPS works! Flash the 360 version, you won't be disappointed.
