Dear forum,
I got an question about full wipe and deleted dalvik cashe.
I am as an lot here playing with 2.2 Roms for the X10.
I read in some threads that there is an solution for the flashing screen after installing an 2.2. rom. It says do an full wipe in Xrecovery and an Dalvic cashe so the screen flashing is history.
When i do an full wipe (after of course do an back-up) does that result in complete disappearing of all my data and aps or can i with restore fixed that?

i have two question. (sorry for bad english)
1) i m using 2.1 stock rom and i want to flash my mini pro to 2.2. if i back up my apps on 2.1 stock rom before flashing, after that can i restore it on 2.2?
2) in xrecovery menu before installing update zip from sdcard,must i select "Factory Reset, Format data, Wipe Cache Partition, Wipe Dalvick cache , Wipe Battery stats" or any other things like that?
Omg omg omg.. pleeeease someone help me.. I tired flashing a rom (phone already rooted and using cwm 5) for the fifth time and it's now stuck in startup on android (in white letters). I wiped system cache dalvik but nothing... what else could I try?
Which ROM are you using?
Try flashing again, and remember to read the instructions very carefully.
Wipe data/factory reset, wipe the cache (although that should be done when you factory reset) and the dalvik cache.
If it still fails, restore your previous backup (you did make one right? It's, like, almost necessary to backup your current ROM with CWM before doing anything, even if it's just wiping the dalvik cache. It's ESPECIALLY necessary to do one before flashing a ROM).
If all else fails, flash a new firmware using ODIN.
Thanks for the quick reply but I managed to fix it already.. I am awesome *big smiles*
You are awesome. Great job.
hello
my phone is sgs2 i9100
i have flashed my phone with odin several times, however i have a few questions.
when i flash a new firmware with odin i usually wipe my device and cache partition before, just in case, but even so, after i flash, my previous wallpaper remains, why is that?..could it be that some old data remained?..
the other question is about wiping dalvik cache, i know it is not needed when flashing with odin, but the last time i used that option my device went into bootloop, if i clear dalvik cache without flashing new firmware, is that normal that my device will get into bootloops?, and should i clear dalvik cache every now and then to speed up my device?
and is clearing dalvik cache is dangerous?..
if i am stuck in bootloop is there an easy way out without flashing again?
and one last question,
i prefer odin when flashing a firmware, rather then cwm, where can i find .tar custom firmwares and not .zip wich require to be flashed with cwm.
these question may have been answered before but i couldnt find them, so all help is greatly appreciated.

Hey mate,
clearing Dalvik Cache isn't dangerous because it's a kind of Prefetch folder from
Windows. So it's there to have some data from installed apps, but often hold it
after uninstall etc.... So don't be worry, u can clear it if u want
Hey mate!
Getting out of bootloop without reflash isn't really possible at most time.
U can try to do a factory reset and hope that system can boot then.
Odin flashable Firmware here:
http://forum.xda-developers.com/showthread.php?t=1075278
Odin Flashable Rom would be for example:
http://forum.xda-developers.com/showthread.php?t=1334124
A factory reset is not a really full wipe... it's like throwing icons in trash bin,
but to delete really u have to clear the trash bin.
So do the following for Full wipe an go in CWM to:
- wipe factory reset
- wipe cache partition
- Advanced: wipe dalvik & wipe battery stats
- mount and storage: format data, format system & format cache
Hope I didn't forget anything of ur points and could help a bit
CHEERS
You could also try the thread - if you have a bootloop?! !? DOH
hi, I'm going to install new rom on my phone, but before I do that, it asks me to wipe date/fectory reset. I understand that part, but do I need to wipe cache partition too??
what exactly does it do?? is it safer to do it???
Cache Partition
wipe data/factory reset will wipe all user data on the device as well as cache. Doing this will leave your phone in the state it was in when you bought it.
wipe cache partition on the other hand wipes the cache partition of the device to clear all the data accumulated there over use.
I think if you want to start building your phone all over again, like a fresh start you could wipe cache partition too.
Nevertheless, I'd suggest you check-up with on of the more experienced developers and see if they second my opinion.
yep, wipe all of it when installing a new rom..
basic flashing 101...
The collective roms format cache and system themselves before installing everything. Only thing needed for our roms is to wipe data/factory reset.
its never a bad idea, especially for n00bs, to get used to a regime of the following:
format system
factory wipe (data /cache/ dalvik)
wipe batttery stats
then flash..
coming from 3 previous android phones, (2 htc, one sammy), as long as I followed this pattern, I never had issues, and, I am sure I have flashed my phone several hundred,(if not thousands) of times..
I ALWAYS perform the following steps when flashing new roms:
1. Nandroid backup
2. Wipe data/factory reset (x3)
3. Wipe cache partition (x3)
4. Wipe Dalvik cache (x3) (found under the "advanced" menu)
Sometimes i even go through the wipe cycle once after i finish, just for good measure!
...happy flashing!!

Its not necessary to do each three times, once is fine.
What you want to do is the wipe(s), then install your rom and let the rom boot. I have had numerous problems with wiping any data AFTER installing a rom but before a full boot into the rom. So basically, I do the wipe(s), then install the rom (WITHOUT rebooting), reboot and let the rom fully boot and you wont have any problems.
Oh, and my understanding is, if you do a factory reset in CWM, it is not necessary to wipe anything else as a factory reset also does the Davlik cache and cache partition, but not only does it not hurt to wipe all three just in case, a developer can feel free to correct me if Im wrong on this point.

I've flashed multiple roms onto 4 different phones and a tablet in the last 3 days (Captivate, SII, Skyrocket, Note, Xoom), and every guide except the one for the Xoom recommended at least 2 wipes of each (cache partition and dalvik, most in addition to factory). factory wipes are not always necessary, but unless the developer specifies that, it is always safest to just do the wipe. it definitely doesn't hurt.
it takes about an extra 30 seconds, with no risk, and lots of reward.
I dunno, Ive started seeing this come up alot in the last couple of months and Im not sure why. I guess it doesnt hurt to do it all 3 times but it makes no difference whether you do it once or three times.
this is an electronic device, its NOT your butt; one wipe does the job..
if you'll sleep better by doing multiples, knock your sox off, but, absolutely not needed, regardless of what you have read..
Hi Guys,

Ive already wiped the cache and delvik cache, only thing I havent done yet is factory reset, was going to do that last.
Backup.
Full wipe;
Format System

Then immediately reflash
Don't restore system apps and data with Titanium etc.
