Info on data wipes.

I was just wondering if data wipes did the same thing on this phone as they do on mine. Just set up the gmail account again and you're good to go...

DO NOT WIPE DATA ON A CUSTOM ROM, plain and simple... unless you're running total stock (or perhaps a stock deodexed ROM), wiping data can be disaster.
Even if you MUST wipe data, please do so through your phone's recovery, not through Android's menus.

Flashed cm last night and I cleared cache but forgot to wipe system. This makes me feel better.
Every other phone people said to wipe system to remove ghosting of other roms. Why shouldn't we wipe system on this phone?

I don't know the rules on cyanogenmod or other completely different roms, but there's a difference between wiping system and data. If the person who put your rom together did a good job, it should automatically wipe what it needs to wipe.
(Custom roms on the Triumph are the exception; /data isn't wiped because it cannot be.)

[Q] update custom rom

Sorry for the ignorance.
I have version 6 of custom rom, if i flash the versione 8 I lose data? Or is it just as an update?
thanks
(sorry for bad english)

If the developer tells you to do a factory wipe or wipe data, then you'll lose your data. But most cases when a developer makes a new version, you can just wipe both caches and update your rom without having to wipe your data.

Just to add a little to the previous post.
You could usually get away with just wiping dalvic
As for doing a full wipe where you would lose your data: thats usually only needed if the dev went from one milestone version to another on the ASOP.
Example from a GB based ROM to a ICS based.

What they said above . In case a full wipe is required as noted by the ROM devs, I would recommend using Titanium Backup to backup your apps and apps data before wipe. You can then restore apps + data after flashing the new ROM or update. TiBu has saved me a lot of time restoring apps after a full wipe.

Thank you all for your responses!
This rom (CyberGR-MOD) run the wipe? Is there anyone who uses it?

[Q] flashing roms without wipe

hi guys...what if I don't super wipe flashing a rom of same version?
I want to switch from android revolution to the aosp virtuous inquisition...
if the roms are made from the same base (3.32) can I flash without wiping and backup?

Prob a bootloop or a hell lot of force closes. Always wipe betas and Alpha's.
You dont need to wipe of you are running a custom rom that updates. But only if the cheff says that you have to wipe.
You wipe your ass after all when you take a **** right?
Sent from my HTC Sensation using XDA

hahahahahahah thanks, the chef says that wipe is not needed (just suggested) if I come from a same base rom....in this case I don't have to, but I'll keep in my mind that I have to wipe my ass....ops, my rom ( XD ) before flash another rom....even if it's same base...

[Q] Process system is not responding. Would you like to close it?

I got this while replying to a text message...
I've been getting quite alot of these, from even various applications. It's driving me nuts!!!!
Is there any (permanent) solution for this??
ROM: Gummy
Kernel version: 3.1.10_IcyGlitch_V14-BS_I896-I897 [email protected] #1
Baseband version: T959TLJL3
I'd be forever grateful if this problem could be solved... I really love this ROM

First I would reboot to recovery, then wipe cache, in advanced wipe dalvik cache, then fix permissions. If the problem comes back , I would back up your apps, msgs, that you want, then, wipe system,cache, wipe data/factory reset, and reflash. Maybe a newer rom.

This is a bug firmware, also sometimes a problem when using swap. I recommend flash newest ROM, they are much better.

I did the first thing you reommended, it didn't work and to make matters worse, ma phone doesn't pass the boot screen....
I quickly rebooted in recovery and made a nandroid backup - followed your second suggestion but i never made a backup of ma msgs because you didn't say so in the 1st suggestion... i can load new roms but can restore from ma nandroid backup

When you wipe dalvik cache, your phone can and will take several minutes to reboot, because it's rebuilding the dalvik cache. Secondly, wiping dalvik cache and fixing permissions wouldn't cause your phone to not boot. Between my wife's and my phone, I've flashed Roms, updated, experimented, fixed, stuff, etc... hundreds of times, and never has a dalvik cache wipe / fix permissions caused the phone to not boot. Hesitant to try to help, because you seem to be blaming me..... But if you can't restore a nandroid, it could be you're on a kernel in which the nandroid backup/restore feature doesn't work, you are running an earlier ICS build.

I'm sorry if i came across like that...
just that the phone is driving me nuts
ALSO.... it's the second time i am seeing where reboot take way longer than usual after restoring from a nandroid backup. I av done quite a few and reboot takes less than 10mins. I attempted one the other day and 2hrs 30mins later all i saw was the splash screen and boot animation, phone HOTT!!
This evening again, it looked as if it was going to do the same thing thing... it passed 20mins, i can't sit around waiting for that again

It sounds like a flash to stock KK4 (Full Reparation) would be your best bet. If you're already on G. B. bootloaders, I would recommend the NO BOOTLOADER version, no use flashing bootloader unnecessarily. After that, I would flash the rom of your choice, following the instructions in the O. P. line by line.
Maybe a lot more current rom.

Then I recommend re-flash the stock kk4 NO BOOTLOADER, format the internal sd, install the ROM again and install all the programs manually, not with the nandroid backup.

Dirty vs Clean Flash

A dirty flash is only wiping cache and davlik then flashing your ROM....
a Clean flash is at LEAST factory reset/data wipe + wiping davlik(factory wipe takes care of /cache also)... Maybe doing a format /system also.
SO let the games begin! Which is better?! FIGHT!!

If I switch ROM's I factory reset then wipe cache and dalvik cache. If it's a theme for example I only wipe cache and dalvik cache since the theme is suppose to be made for your ROM right?....don't see the reason to reflash the ROM as well.

Wipe data? What's that for? Is THAT why my phone won't turn on..........
Nightlies: No data wipe (yes to cache/dakvik)
New rom, even if it's the same android build: always, full wipe
Themes: No wipe at all, flash right on, right after flashing rom's. Don't like to wait for two bootups!
Sent from my SCH-I535 using xda premium

Il throw a vote to whichever works.. I usually dirty wipe.. If I have issues then clean it and try again.. With nightlies I tend to be fine dirty a lot, but even still I will do a clean every couple weeks just because..

why do so many folks wipe cache and dalvik after they wipe data? A data wipe/factory reset wipes all three, there is no need to do anything else.
I always wipe data, flash rom, then advance restore data only from a nandroid...dirty flashing in its most elegant form

So we all agree that a dirty flash is just wipe cache/dalvik cache.
Do you wipe prior to re-flashing, or afterwards? Does it matter?

What about flashing a new, updated kernel for a rom you're currently using? What steps should be taken for that? For example, cleanrom 2.1 comes with cleankernel 1.1, but the kernel has been updated to 1.2 and is out as a seperate download. How would you update just the kernel that's made specifically for the rom you use?

When I dirty flash, I wipe data cache n dalvik cache. Once I flash what I wanted, I wipe those two once again n select "fix permissions" just in case

I disagree. I believe a dirty flash also wipes system. If you are 100% certain that your ROM build effectively wipes system as part of it's install routine, then you could skip this step, however I always wipe system to be safe. This works for me and I rarely need to wipe data or sd card(s).

When changing Kernels but not the ROM in a separate recovery session than a ROM flash, you don't need to "dirty wipe." Just wipe cache and dalvik. Dalvik wipe is key so that the dalvik virtual machine can be rebuilt by the new kernel.

Thanks for the info guys.

I usually dirty on nightlies until I have issues. Always clean when switching roms.

It is always good to complete wipe when switching roms.

What if im just switching between stock rom nandroid backups? Can I just restore from one to one? I only have two backups anyways both for stock. Never flashed a rom before

I find that this method works better than just wiping cache and dalvik, since im advance restoring data over a clean flash. both ways are considered dirty flashing tho.

I wipe dalvik, cache and battery stats. Works like a charm thus far. Wiping data is what blows out the IMEI correct?

Incorrect, flashing anything is what may lead to losing your IMEI. Backup using the appropriate tools in the development section. Btw stop wiping battery stats, it's not necessary.

Factory reset doesn't touch the davlik(Which I speculate(Guess) has to do more with the kernel than anything)

Usually when I flash a new kernel, or a different kernel, I just wipe the davlik cache and I am fine. There was some reboots after the first boot on the AOSP ROMs but afterwards it ran fine.

SlimSnoop is correct. According to one of the developers of a very prominent ROM the IMEI issue was because our phones got confused sometimes(Randomly phone to phone) and tried to reset during a flash. The data it tried to reset was bogus, therefor losing IMEI. He is also correct far as the wiping battery stats. It's only usefull when you have really strange results with battery. Google for the real reason to use them.
Far as backing up your IMEI so you will never run into the problem of losing it.... go into your terminal (almost every ROM has a Terminal emulator)
Type this:
su
then hit enter. Grant permissions
then type:
reboot nvbackup
then hit enter. This will make your phone do some shyt and reboot, but you really shouldn't need to worry about your IMEI after this. Regardless of how many ROMs you flash or what you do or who you date or who you kiss, etc... blah blah....
This really should be the end all for the IMEI...

New rom only when their bases are different , like going from ics to jb, or the dev says to do it (Even then Ill try it without a wipe because im lazy).
Themes I never wipe anything
Nightlies never wipe anything.
Edit: If I do have issues I then go back and wipe delvik and cache . That usually straightens out any issues and allows me to keep my setup.
