[Q] Wipe Question - Nexus One Q&A, Help & Troubleshooting

i wipe factory data and cache and dalv cache and still if i do this i get the same background i had like preveious versions of the rom....???
do wiping the phone really works??
to be more specific.... i used the cyanogen mod 6.0rc2 rom used a background with it i then wipe everything i can to try out a different rom works fine then went back to cyanogen mod night version or something it brings back the wallpaper i had use in older version roms i used???

I think thats a google backup/restore thing. If the image/wallpaper is available when the phone is reinstalled then it will restore the background.

[Q] Galaxy S Boot Screen hang meaning?

Hi all,
So after I flash a new ROM (MIUI MGv2/RC8vC/MGv1) I always hang at the Galaxy S GT-I9000 screen - the first boot screen.
I am wondering what this means? is it a corrupt file, something wrong with my internal sdcard, ROM not installed properly?
Please help,
Thanks.
some times a wipe from recovery will help and goes back to normal boot
many issues may cause this problem for instance if framework.jar or android.policy.jar or... have some bugs , will happen like that
Hi,
By wipe you mean clearing the formatting system, data, cache, dalvik cache and a factory reset? I ask this because the MIUI roms are not are non-wipe and the instructions recommend you to format those places before install (which I did).
I mean wipe cache partition from recovery. just try it and ley us know if it works
Well I just tried again but it doesn't work because I can't access recovery mode. It hangs at the Galaxy S screen and doesn't move from there so I'm wondering why because if I can't fix the bad install then I can't access the recovery mode and can only flash.
if recovery dont work BUT download mode does,
start the whole process again, flash back to stock froyo with froyo bootloader.
did you come to MIUI from Gingerbread ??
Well i've done the process like 10 times, nearly every single time from froyo (JPU,JS5,Ezbase 2.0) and I also went from 2.1 to 2.2 and then to MIUI. The other times I have tried coming from CM7 as CM7 works.
well i have a similar issue but in my case i just wiped my data thru cwm on darky v8 xxjpy..
now i get boot loops,any idea what should i do??
i know this is not exactly the thread but if i get my answer it'll save me from starting a new one..
When I got bootloops i normally reflashed. If you don't have data it will probably work?
I assume you have data as your on Dark v8 when V9 is out?
i dont understand by have data??
i flashed v9.5 but went back to v 8 few months ago..
today i just wiped/factory reset my phone using cwm and it was succesful but now its bootloops and vibrations..
i never wiped my phone before and only have flashed using cwm,never used odin for flashing roms!!
OH I see, by data i meant personal data that you might want to back up...I'm not to most knowledgeable but I know how to flash roms. I reckon you should try to flash V8 it again if you can enter recovery.

[Q] Why clear Dalvik and cache?

So every single rom for any phone I've seen says to clear the dalvik and the cache (or maybe its just the "dalvik cache") but when I went from stock to Thriller, I forgot to, and nothing went wrong. In fact, all my settings and apps were all intact from the previous stock rom.
I've considered that the only other phone I'd done any flashing on was a backflip, without Apps2SD and maybe that's why all my apps and settings were intact, so that still leaves me with the question: why clear it?
This may be a noob-ish question, and I apologize. Thanks for any help!

If there are any compatibility issues between the apk dalvik cache of your previous rom and the apks on the new rom wiping dalvik clears the previous apks stored dalvik cache. In most cases you can flash without a problem. But I recommend wiping between rom flashes just to eliminate any potential problems. Flashing something like Thriller over the stock rom you can probably get away with not wiping anything since all the apks are essentially the same. Flashing kernels you don't need to wipe anything. When flashing a rom with a completely different firmware I recommend a full data wipe. Restoring recovery backups such as nandroid require no wiping at all.
Also, wiping dalvik shouldn't affect any of your settings.

When switching ROM with different base apps, it is generally better to wipe caches than to get stuck in a boot loop, or having your apps and launcher FC on you. You never lose anything as the cache rebuilds itself on the next reboot, except maybe a few minutes

If you followed the instructions you did a full data wipe. When you do this the dalvik gets wiped as well. To just wipe dalvik look under the Advanced menu in cwm recovery.

clearing cache
i am using a nand rom in my HD2, and i also want to install another rom via SD in Magldr, but because of kernel issues i cannot load the Rom from SD unless i use the kernal i am advised to use. I am instructed to clear the dalvik and cache, but does this mean that i would lose anything from my current NAND rom? I still want to be able to use that of coarse so i just want to make sure there are no major risks when clearing cache.

Clearing dalvik and cache wont make you lose anything, used to do it with my shift because I'd flash about 10 zips a day sometimes...
Also when it comes to flashing any ROM I format system data cache wipe dalvik cache and do a factory reset just to be sure nothing from a previous ROM is left over also wipe my SD ext partition when running an a2sd ROM, my question is can I safely manually format the emmc partition of the thrill from the mounts and storage option of cwm

[Q]Is it possible to update ROM version only?

Is it possible to update the current ROM version without wiping the data and apps installed on the current ROM version.
Currently I'm using squadzone's ver5.2 and I'm planning to use the ver5.3.
Can I just install the ver5.3 without wiping my current data and apps?

Though this is not recommended, you can try not to wipe data and apps.. If your phone boots to homescreen after you flash 5.3 without wiping, well and good.. But if you get stuck on the boot splash screen, you have no choice but to do a data wipe.. Best option is to backup app data with TBP (Titanium) and restore them after you do a clean flash, that is wiping data/reset, wiping cache..
Hope you press the Thanks button if my post helps..
kitrax59, it is not so bad as you think. I tried lots of times to jump from one CyanogenMod to other without wiping, and it worked rather OK. i didnt notice any problem. ecyaj, you may not wipe, but if you notice some bugs - it is recommended to wipe data
Thanks for the info GallardoSD..., but it was too late. I just wipe everything and installed squad's new v5.4. I used TBP and did restore them after flashing. It was just I need to setup everything again...

[q] lg optimus 2x frozen even when reinstaling rom

Hi, im having problem with my o2x. Frirst phone started to behave strangely and every application has stop working. Error was
"uids on the system are inconsistent you need to wipe your data partition or your device will be unstable"
and then every time i restarted the phone it was the same error again so i decided to reinstall rom. Than error was gone but other problem appeared, now after 3 min of use phone get frozen and than i reinstall rom again and phone get frozen agan.
Please if someone can tell me what is the problem and how can i fix them.
You have mentioned reinstalling (reflashing?) the ROM but you haven't mentioned a factory reset so I have to ask... Have you tried a factory reset?
Should i do factory reset on rooted phone? if yes how can i do that. I read somewhere that factory reset should not be done on rooted phones. is that true?
In CWM, You always have to Wipe your Data,Cache,Dalvik Cache,Battery stats.
Optional : Format System.
For a rom to function well, else it will get all kind of problems, like you have.
Of course if you install a update for a ROM, you only have to wipe the cache/Dalvik Cache.
Remember to make a Backup of your apps with Titanium Backup.
I didnt wipe Dalvik Cache and Battery stats. I'll give it a try. What does Format System do?
The factory reset basically resets your phone to as it came from the factory. It erases all your settings and apps, and is recommended that you do that when you change from a stock ROM to a custom ROM.
Having root has nothing to do with it.
Me personally I like backing up my apps and doing a factory reset each time I change/update my ROM. This way I make sure I always have a clean system each time. Of course this might not be convenient if you like flashing a new ROM twice a week
Wipeing Dalvik Cache, Battery stats and factory reset didnt do the trick. I flashed cyanogenmode nightly now and its ok for now. Could it be problem with the rom?
"Factory reset" (/data wipe) doesn't wipe system apps. If you had on your old ROM some "broken" system app, you most likely still have it. First thing i would do is full device wipe (/data and /system partition wipe). If you dont know how to do this here is the script and how-to. Be aware of that this script can brick your phone (ofc then you can fix it with smartflash) is you won't follow instructions.
After that wipe and ofc flashing clean ROM (btw. which is it?), it still isn't working, it's most likely ROM's fault. It could be Baseband<->RIL problem eaither but i've never saw RIL problem which has influence of system stability.
Are you flashing back to stock or a custom ROM?
If you are flashing to a custom ROM, you need do all the wipe-steps and then do BacktoEXT3 before flashing the custom ROM,
