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 Guy,
I got a BIIIGGG problem.
After doing some VERY quick research i decided to get started by rooting and installing VillainROM, which worked lovely...no probs, however because there was a lack of themes (the main reason i rom'd the phone), I was swayed to go for Cynogen.
After downloading CM7.1 and installing through CWM my phone will not boot.
I have tried to do a factory reset through CWM, wipe the cache, and reinstall VillainROM but to no effect and stupidly i didnt backup my data.
Any advice on what i can do or have I bricked my phone?
What does the screen show? Can you get into download mode or recovery? Have you tried flashing the rom twice? This worked for me in the past.
Ricey
yep i can get into recovery and download mode, but when i boot the phone no joy
Ive tried installing the rom several times
Try formatting /data, /cache and /system from CWM recovery before flashing the new ROM.
If that doesn't help flash a stock ROM from Intratech's thread in the dev section via Odin.
1st- Boot into recovery.
2nd- wipe data/factory reset
3rd- wipe cache
4th- go to advanced/ wipe dalvik cache
5th- go to mounts and storage - format/system
6th- go to install ROM from SD card - select the ROM you'd like
7th- reboot system DO NOT TOUCH MAY TAKE A WHILE
8th- let it sit for 10 minutes once its booted so all the cache can build back up
9th- reboot, set up, and enjoy!!
Hope this helps!
Enzopreme you are a legend many thanks indeed
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.
I was flashing CM9 from CM7 on my Motorola Defy, botched it up intially due to a slip of my finger which led to me to Clear the cache first. But then I restarted the entire process by Clearing Data -> Installing -> Flashing Kernel and so on...
But when I tried to clear the Dalvik Cache, the phone didn't delete it. It didn't give me a message that it wiped the cache, but it didn't say otherwise either. This led me to believe that the cache just didn't exist anymore.
As a result, I'm unable to install apps - Says there is no memory and I need to make more. Also, everytime the phone comes on is treated as the first time. It takes me through the whole process of Setting up an account and everything. This has rendered my phone obsolete.
Please help me!
Thanks in advance.

EDIT: Solved, reflashed the stock SBF. But is this the only solution? :O
Have you tried doing a clean install?
Honestly, any time you get issues like this where the phone gets stuck (either in a boot loop or resetting your settings every boot, etc.) it's best to just wipe/factory reset and re-flash everything.
This is also why it's important to make backups so that if something does go wrong when flashing, you can just restore and be good to go.
If by a clean install you mean starting from wiping data, flashing the ROM on again and going on to clear cache and dalvik cache; Yes I did that. But I'm unable to clear the cache.
I ought to have created a backup, didn't.
So how can I go about fixing this issue?

A clean install seems like the main thing to do (again). If you want, you could try going back to stock.
Installing again didn't do the job. Still can't wipe Dalvik Cache and the Setting still reset on every boot.
The chief problem I have with this is that I'm in India whereas the stock baseband is Europe. So to change it I've to reboot and can't do that because it resets every boot. @[email protected]
Is it a problem with the Kernel?
I'll go back to stock, but it seems a bit complex and I'm afraid I'll brick my phone. :'(
EDIT: Felt it was important to mention that the boot screen still shows CM7.1 and not CM9
I have a similiar problem.
Everytime I choose clear Dalvik men, it looks like he freezes for about a second or two. Then you see the 'menu' no - no - no - no - yes, clear dalvik memory - no - no - no (or something like that) pop up for half a second, and then it is gone. Is this a problem in CWM? Or is it in my phone?
I have a similar problem too! When I hit 'clear dalvik cache', the CWM screen just flashed once and nothing happened, and nothing says 'cleared dalvik cache' or similar...
Me too , how to solve it? Can anyone help? Mine is samsung gio
I have an issue similar to yours with my tablet (samsung galaxy tab 4 10.1 or SM-T430NU) in which it doesn't mount /data and it doesn't let me wipe to factory. Still haven't found how to fix this.
Hello, if i do a reset inside the OS, will this wipe and delete the cache same way as a hard reset with the physical buttons?
Yes. But both do not only delete the cache but everything on your phone's internal storage.
It's noteworthy that CWM (the alternative Recovery) keeps the /sdcard folder intact

So if i understand this right, both ways, like, the usual inside the android OS itself, on the S3, or the reset trough physical buttons, both delete the cache aswell?
can someone please explain a full wipe - when asked in a rom thread that you need to do a full wipe. what is that?
do you do it in CWM only, no where else?
- wipe data/factory reset then
- wipe cache partition then
- wipe dalvick cache
that's it? that's considered a full wipe? because I was reading and something said if coming over to xxxx rom from aokp do a full wipe.
tbh I've already changed roms but I hard bricked my last phone not knowing things like this. lol
thanks

Yes that is a full wipe, but "wipe data/factory reset" is enough, no need for the other two.
Also if you just flash a wrong rom, I doubt your last phone is hard bricked. You can donate it to me.
thanks for the answer.
with my galaxy note I installed a stock ss firmware via odin, installed CWM and then flashed aosp without wiping or anything. phone couldn't get into recovery, download or turn on. jigs didn't work and a shop also couldn't get it back into download or recovery.
so no signs of life, I've already sent it overseas for warranty, sorry mate
I ended up getting an s3 till note2 comes out. but I heard the note2 will only have 512mbs of more ram than the s3, and it won't be quadcore. if these are true I'll probably torch all my samsung devices and get apple products -_-
Recently i have flashed several kernals. I always did all wipes with cwm. Are there reasons to use a tool to clear old kernals? What will happen if i format boot partition with cwm? Will this operation clean old kernel's traces?
I try to be more clear
When i do all wipes (factory reset, cache, dalvik) do they clean also karnel?? And, what is boot format option in cwm? is it safe to do?
Thank you for attention.
