[Q] CM7.02 update question

Hi everyone,
When upgrading from CM7.0 stable to CM7.02, do I have to do a full wipe and install or can I just install on top of it and keep all my apps and what not?
Thanks

You don't need to wipe at all. Just flash the rom over the top of the old one.
Some people wipe cache and dalvik cache between flashes others think its a waste of time.
The only thing I would suggest is to flash manually through CWM rather than ROM manager.

When to wipe cache and dalvik cache

Hello people!
Have searched the forums and also tried googling but have not found a certain, conclusive answer to my question.
The question is when do we have to wipe the cache and dalvik cache?
I know what to wipe when flashing a new ROM but what about radios, RILs and kernels? What do we have to wipe when flashing the above so as for the phone to run optimally? Before or after flashing them?
Thanks in advance

Developers of the rom will tell if a full wipe is needed , if your updating. If your coming from another rom, you need to perform a full wipe.
No wipe required when flashing radio, Ril and kernel.
If you are going to perform a wipe you do it before you flash anything.

You mean you don't even have to wipe battery stats when flashing a new Radio?
I thought otherwise but I am not certain...
Anyway, thanks for answering

As far as I know you don't need to, the only time bat sat are recommended to be wiped is when flashing a rom and you have battery issues. But others say wiping battery sat doesn't really help with battery..

Ok thanks for the info!

Did I Flash M5 right?

I flashed AOKP milestone 5, I was coming from M4. I backed up SMS, pics, music and synced to Google for contacts in anticipation that when I wipe/reset I'd lose everything...
Flashed m5 and gapps after wiping and when I rebooted Android started to upgrade them it said something about apps and went configuring apps 1/138 and so on until it was done.
I was booted back into exactly what I had before same settings, apps, music. I went to about screen and I'm on M5 and 4.04
Did something go wrong ? Should I of had to get all my stuff back? Did I do a dirty flash somehow?
Thanks for any help.

Sounds like you didn't wipe it properly if it is working good no need to now but if you have problems then you should wipe and reflash.

Did you wipe all 3 areas? And how many times did you wipe?

Any extra input on this? Shall I reflash, I've been going for a few hours now and haven't noticed any problems but I want to be on the safe side

Check the Android revolution thread for the super wipe zip. Flash that then re flash m5.

You are good. It was rebuilding dalvik cache from you wipe before the installation.

So any reason that when I wiped, it well, didn't wipe? I only did data/factory reset in the recovery menu.

You didn't wipe cache and Dalvik cache.

Factory/data wipe formats cache & data.

I wiped, cache, dalvik cache and data/factory reset then flashed AOKP M5 and Gapps again. When i got rebooted, its the same thing.. all my music is there, pics,sms, contacts, apps.
Why wont the phone let me wipe and install a rom fresh?
Is it because im already coming for aokp m4?
It is something to do with Clockwork mod?
Please help.

Try that super wipe lite zip mention earlier or go into the mounts section and format data, cache and system. Then wipe dalvik. Flash rom & gapps again.

i had this problem before when doing factory reset from cwm. i just use fastboot to flash stock 4.0.4 then use cwm to flash aokp.

1) wipe data/factory reset
2) wipe /system (if you don't wipe this partition it leaves settings and files from the previous rom that could prove problematic)
3) wipe dalvik
4) flash rom
5) flash gapps
if installing a kernel after wards
6) wipe dalvik (again)
7) flash kernel

The music and pics should matter unless your wiping the sd card in recovery the SMS should have been gone after a wipe though

Yeah the SMS is still there.. idk what to do its not like the phone doesn't work or anything but its weird that I can't wipe and start clean I'll prolly have to unroot/ lock the boot loader and start all over. If anyone else has any input, please share

[Q] Is it ok to reinstall a rom without clearing anything?

I flashed Sandvold's ICS 0.8.1 yesterday, but after reading a few threads today I saw that it's better to do the custom install instead of the typical one. I did a nandroid and decided to simply flash the rom again without clearing anything.
It seems fine so far, but I'm wondering if this can lead to any problems?
Also, do I need to reinstall a2sd after re-flashing?

I think that if you downgrade from ics to gb than you need to make a full wipe but if you upgrade than I think it's ok

If you are with the exact same rom then a wipe shouldn't be needed and a2sd should stay if you don't wipe.

Try it and if it doesn't work do a full wipe I've never seen anyone say you'll break your phone if you don't wipe. Someone on Sandvold's thread recommended app extractor from play store as an easy way to restore after a full wipe. Didn't work for me but I only tried it once so you could check that out. It just restores everything from your nandroid

If u are flashing the same rom (newer version) u still have to wipe dalvik. Its better anyway just to do a backup then full wipe and flash the rom then restore
Sent from my HTC Desire

Always wipe Dalvik, sometimes, the rom setup menu does it automaticly.

[Q] noob question on reflashing a rom

I flashed CM10 a week or so ago and I want to update to the newest version of cm10. How do I go about doing this? Is it as easy as I think? Download newest version, put it on sdcard, boot into recovery, and install from .zip or do I need to do something else? I'm sure this has been asked before l, sorry. Thanks for our help.

It's recommended to do a full wipe. Than flash the new update zip.

Does a full wipe consist of just booting into recovery and wipe cache partition, delvic cache etc.?

Anyone else know?

Preparation
Before doing the wipe, make sure you take the following precautionary steps:1. Perform a*Titanium backup*to ensure you have the latest versions of your apps saved. Its a good idea to save your internet bookmarks here too.2. Many apps have a backup/restore option so use this to back up your current settings (eg. JKay Deluxe settings, Go Launcher, Fancy Widgets, Simple Calendar etc.). Do this for such apps so that the settings can be easily restored later if required.3. Make a Nandroid backup through CWM Recovery.Be aware of any contacts with personalized ringtones etc. as these will have to be re-assigned after the wipe. There are apps on do download from the Play Store that can save these for you however.
