If I want to update my MIUI rom, can I do it by only removing cache only or do I have to do the factory reset?
Only cache and dalvik cache (advanced-->clear dalvik cache) is needed. If you're running 2.3.3 or 2.3.4 it's a good idea to do a full wipe before upgrading to 2.3.5.
Remember next time that you only need to wipe the caches and simply flash the zip. Easy peasy!
- If you want to flash a new ROM, then you'll need to do a full wipe.
- If you only want to upgrade from 1.x to 2.x you only need to clear cache and dalvik.
- If you want to upgrade, but the upgrade includes jumping to a new version of Android (2.3.3->2.3.4->-2.3.5 etc.) then it's a good idea to do a full wipe. It's not needed, but again, it's a good idea.

i personaly never do a factory reset or full wipe unless its recommended by the DEV. this way all my settings and aps are saved and still in their respective spots when switching over. most of my experiences are trial and error based.
just remember always NAND backup before you do anything. its just a android life saver. this way if something doesnt workout you just go back and start over

Hello,
I flashed CWM and did a full system backup/system wipe/cache wipe then installed xboarders 1.2.2 rom for the first time. I'm rooted! woohoo! I want to install eaglesblood new rom now. My question is when installing a new rom is it recommended to do a full backup or is one time enough? Thank you for any help as I am a newbie at this.
I always keep at least one or 2 backups of setups that I know work. That way if I screw something up while tinkering with my phone I always have a working backup to fall back on.
So yes, its recommended to keep a good backup on hand. You don't necessarily need to backup every time though. I just make sure I backup my texts before I flash anything. I hate losing those.
What you DO NEED to do EVERY TIME you flash between completely different roms is do a full wipe before you flash the new rom. If you're only updating to a new version of the same rom then a full wipe isn't necessary.

Thanks for your help! Also, when doing a full wipe do I need to do a dalvik wipe as well in the advanced settings in CWM?

I always do. It certainly wont hurt anything if you do. Just remember the first boot after clearing dalvik cache usually takes a little longer than normal because the phone has to rebuild the dalvik cache. Don't panic if it takes a few minutes even to boot. After the first time it wont take as long.

I'm not sure if this is supposed to go here, but I want to install MIUI-XJ on my HTC Desire GSM
http://forum.xda-developers.com/showthread.php?t=957291
I really know nothing about when wiping is necessary, I know it's good to wipe cache to speed up the phone but I'm always advised to wipe my data/factory reset when installing a new rom.
I'm wondering, when installing MIUI-XJ over stock MIUI without flashing, do I really need to factory reset?
I don't have many apps installed, just I want to know when and why it is really necessary.
Thanks for any feedback <3
I'll have a look around
hi,
i just rooted my mz601 3.2 and i want to install the ics everest.
can someone please let me know how i can wipe the xoom prior the ics flash?
i have cwm recovery installed .
many thanks!!
Boot into recovery you'll find a list of options there. It would also be a good idea to read "Xoom Heaven" posted in the general section first.
Your going to have to Wipe Data and factory Reset, Wipe Cache partition than scroll to advanced and Wipe the Dalvik Cache. After that go to Install zip from SD card.
thanks Guys,
i manage to install the Ics and everything is fine.
what cache / data do i need to wipe when i will flash an updated ics rom?
do i stiil need to wipe all of the above and loose my aps and data again?
thanks!!
I Personally like to do the full wipe thing, just as you did before. Because that's one less thing you don't have to consider when having problems.
Hey Folks,
lets say im running CM9 version 10, and the developlers just released version 11.
I want to flash v11, do i have to backup all my data (via titaniumbackup for instance) or can i just flash the rom and continue there where i left?
And, do i have to do a full wipe, clear cache part, clear dalvik cache (via clockwork recovery) ?
regards,
mike

Always better to backup and nandroid, and do a full wipe. That way if you run into any problems you know it will be because of something that's going on now, and not something that was left from the previous versions.

technically you can just flash version 11 over version 10 without having to wipe or backup anything at all, everything should work because you are flashing a ROM of the same base.
however, it is always recommended that you backup (either titanium, nandroid or both) before you flash.
And also, usually wiping data is not necessary, but wiping cache and dalvik is recommended.
Hey, I'm currently on MIUI ics. I know I have to wipe/factory reset everything. But is it safe to flash on the current CWM? Or do I need to update it or something? Do I just flash the new JB rom like I would switching from MIUI to a stock ics rom? I'm a noob, sorry if this doesn't make sense.
What version of CWM are you running?
You should be fine, but it never hurts to check. You flash a JB rom just like any other. Wipe wipe wipe and flash.
The whole wipe wipe wipe is completely unnecessary. One wipe is sufficient and any additional won't do anything.
It's like saying that unless you wipe exactly 3 times the Android Gods are going to demand a human sacrifice for your phone to boot.
lol i think dvorak meant wipe cache, wipe dalvik cache, wipe data (wipe wipe wipe) but that's my take..
anyway, if you can flash MIUI ICS with whatever CWM version you currently have, you should be able to flash other JB ROM. Nandroid as always.. Goodluck!

This is what I did :
1. Boot into recovery and perform a nandroid backup of my MIUI installation.
2. Wipe.
3. Flash XenonHD 9 JB ROM + marmite 4.2 kernel.
My phone is running really smooth now. Good luck.

Yep, that's it. Of course wiping everything 3 times would be unnecessary.

if you get a cluster f*#@ of problems then clean install. It isn't that hard. Use Titanium Backup and good to go.
In Recovery:
1. wipe data/factory reset (this formats /data, /cache and .android_secure on sd)
2. format /system, /boot
this leaves you with only bootloader, recovery and radio...dalvik-cache resides on /data, so it's gone already.
3. flash rom
4. gapps & custom-kernel (if needed). No need to let the phone boot & settle before flashing them (most custom-kernels have a script that automatically wipes /cache & dalvik during kernel-install)
5. reboot
6. Run TB -- restore missing apps with data --1st option under restore
just updating rom:
1. flash rom-zip
2. wipe /cache and dalvik-cache
3. reboot
Do this before reporting any issues on the thread since the problems are often related to this and not the ROM or kernel.
