[Q] How to ensure a clean ROM install

After playing around with several ROM / kernel combinations I am looking to return to the latest stock Rom. I have the PC36IMG file on my SDcard and will be installing via ClockworkMod recovery. What is the proper procedure to ensure the cleanest possible installation? Im a bit scared of all the options in recovery such as all the format options in the partitions menu. Do I need to format everything? Will any files be carried over? I know I will need to re install Clockwork and SU app just want to make sure everything is as clean as possible. Thanks in advance.

cleanest possible? Flash this in recover. It wipes 100% of every every time.

If you are just changing kernels, choose wipe catch and delv catch.
Changing to a different rom you need to wipe everything.

Thanks for the tip. I am running a custom kernel so I'd be looking to wipe all of those files as well as the ROM. The ROM I am using is just a re packaged RUU, does the RUU completely wipe all data or will I still need to manually wipe?

You should always manually wipe. I never count on something else to do it for me. When I am changing roms I always wipe data/factory reset, cache and davlick, plus I use calkulin's format all tool that the other responder to your question attached to his post. That way you know nothing will be left over. Before you do all that, remember to make a backup of your current configuration just in case something goes wrong. I have been bailed out by nandroid backup a few times.
Also one more thing, there is a Rom on here that is the latest stock already rooted which would make it much easier on you. You could just wipe and flash and still have SU and all other benefits of having root. Just a suggestion.
I found the stock rom thread. It has both odexed and deodexed version. Odexed will probably boot faster, but deodexed can be themed and/or modded. Heres the link: Stock 3.70 EVO Rooted

I reccommend clearing the cache, and then wiping the dalvik to ensure a clean rom. After that, just flash your rom. As always if you are unsure, you can backup your SD card.

[Q] How to install extra RCMixHD v3.0

Hi, I have installed RCMix HD, now how must I do to install extras?
Thank you.

Just like the ROM. Flashing the .zip files.

and this doesn't cause any damage to the installation, is it right?

No, it does not.

Thanks a lot. And the kernel? is it important to install?
For install extras and kernel, must I even do:
wipe data/factory reset
wipe cache partition
wipe dalvik cache
?

DO NOT WIPE a thing... you'll have to Re-flash everything then.
Just Flash it as normally would. (However it depends on the extras - some people said that for the Power notification extra you need to wipe dalvik if it is NOT Working).
Kernel? If you are not satisfied with the stock RCMixHD kernel, then you can flash others, just as the ROM, no wipe.

and if would I delete extras after installing?
I'd wand delete Customizable personalize button...

Make a NAND backup before you install something.
If you don`t like it, you can go back to the NAND backup.

I have installed it without NAND backup...how can i delete it?
how do I do NAND backup? with ROM Manager?

Nandroid backup can be done via custom recovery (CWM or AMONRA).
Now you can't delete it, just if you do a full wipe and re-flash the whole ROM AFAIK.

How would i go about changing too CM 7.1.0?

Hello i am currently on CM 7.03 and am wanting to change to CM 7.1.0.
Is there any way of updating the software without flashing the new ROM?
Also to update by flashing the new ROM do i just have to wipe cache and reset factory settings then run the zip from CWM?
Thank you for your time.

u only need to wipe cache and dalvik cache (only to be sure) and flash the update..thats all
no factory reset or other wipes are needed

So am i right in thinking that too change between ROMS thats all that you have to do? (obviously having made a nand backup)

yes and u will not lost any setting

Ah that's good. I will still do a back up of all my messages and contacts regardless.
I thought i would lose everything again, considering that the first time that i flashed a ROM i came from stock and rooted with Revolutionary.

you lose everything when u do a factory reset/wipe user data from the recovery
the factory reset/wipe user data is necessary when u change the rom (like going from a sense rom to cm7)
but when u just upgrading (cm7.0.3 to cm7.1) u dont have to factory reset/wipe user data..only wipe cache and dalvik
btw always do a nandroid backup before upgrading

NAND backup, flash the rom, flash the gapps. You might want to clear cache and dalvik-cache too. It shouldn't be necessary to wipe your data.

and what if I also want to flash a new hboot and don't want to lose all my data? can I first update to 7.1 (from 7.0) then do another nandroid backup then flash a new hboot (which require wiping everything, I understand) then restore from nandroid backup? Is that possible or there is another easier way to do it? thanks

That should be possible if you are flashing the CM7 hboot and have not modified any system files as the partitions should still fit after the hboot update. However I recommend you do some more research or back up your data with titanium backup (in case it fails).

Installed CM 7.1.0 by just wiping the cache and dalvik and it all worked perfectly.

[Q] N00b updating Custom ROM

I have installed MildWild CM-2.7 on my Desire but there is now MildWild CM-2.8 and I can't find a guide how to install/update my Desire.
I have got S-OFF and recovery by Revolutionary The guide I followed to S-OFF and ROOT
This is the ROM I using. MildWild CM ROM

Just flash it via recovery like you did with the previous version

Will flashing the new version cause me to loose everything on my current version I.e apps and data etc??
Thanks for the reply though

do back up first, wipe davik+cache and flash it... it should work if not do full wipe and restore back up
just post any result we will move from there

What should I use to hackup TIbackup? Or is there a better one that you reccomend?

Do I only restore the Titanium I am guessing, as restoring recovery would revert back to my current ROM? and I have thanks

Yes indeed. With titanium, only restore "missing apps with data".

Things I've learned with all this flashing that may be helpful for you.
1. Before flashing, always backup your current system up. nandbackup via recovery, titanium for your apps, sd card if really needed for that you need to do.
2. If flashing an updated version of same rom, wipe cache and dalvik only on your recovery (unless explicitly specified by dev to make a full wipe.)
3. If you are having weird issues after upgrading the same rom, do a full wipe and start fresh. If issue is not resolved, report the issue to the Dev's thread.
4. Do a Full Wipe on recovery (System/factory, cache, dalvik if coming from a different rom).

Thanks for the reply.
In response to 2. I am using ClockworkMod as my Recovery and I am guessing you mean I have to wipe 'cache partition' and 'wike dalvik cache' under advanced?

Yes if I remember correctly there are the first three lines on that recovery is wipe system, cache partition (like you stated), and wipe dalvik. So if upgrading just wipe cache partition and dalvik cache.
System partition is where the "Android OS" resides. Wiping it is like formatting your computer. Most of the time, incremental updates of the same rom requires you to wipe just the cache partition and dalvik, otherwise if the rom update has a lot of changes, the dev might require you to wipe all three options on the recovery.

Having wiped my cache and dalvik cache. I am now wanting to install the new version. On the main screen I have 2 options which are tempting to click.
One is 'Apply update from SD card' and the other is 'Install zip from SD card'
I am unsure of which to choose but my gut instinct is to go with 'Install zip from SD card', is this correct or am i going to make a terrible mistake?

[URGENT]How do I restore from a NANDROID?

I went through a few guides about restoring from NANDROID backup, but all of them didn't mention about Wipe Data/Factory Reset or Wipe Cache etc. So I'm curious and don't know what to do now. Do I need to wipe?

Yes.

This? In the steps there's no wiping. So if you confirm to me here I need to wipe, I'll listen. So the answer is yes or no? And if yes, do I need to wipe cache?

Read the guide in post#7.
Yes to wipe.

It's always recommended to wipe to get a clean environment, especially if you want to restore to another ROM than the one you are currently on, you should wipe then Restore NAND.

Wiping is recommended, but often times I don't (just don't come screaming if things happen )
When you restore a ROM, all your existing system information is overwritten, so it shouldn't be an issue. Sometimes if the ROM you're restoring from doesn't contain a certain partition (like dalvik cache), but the ROM you're on right now and changing from does, you can get issues, since there's no dalvik cache to replace.
That's how I understand it at least.

This is what I do when I install a new ROM
I Use 4EXT Recovery Touch
Step 1:- backup | restore --> Backup
Step 2:- wipe | format --> wipe data/factory reset --> wipe cache --> wipe dalvik
Step 3:- install from sdcard --> choose zip from sdcard
Step 4:- full wipe
That's it.....

I stand corrected. It seems one doesn't have to manually wipe when restoring a backup. At least in 4ext it is done automatically. I'll be taking a look at it later and edit this post if I'm wrong. Just in case
