Does flashing a stock ROM Unroot? Nandroid data wipe?

Hi guys, noob help needed.
Sat back for a while and eventually took the plunge yesterday to root and try some custom ROMs and all went fine - thanks to all those who put the time in for the tutorials and tools.
I've come from Stock Orange and the battery life was great which I know others weren't reporting, but since using the custom ROMs I've noticed an increased drain - I need good battery life for my working day.
I've got fake flash and nandroid to make it easy to skip between ROMs, but the stock HTC ROM I want to use for work (no Orange bloatware) is a .exe installer.
So, my noob question - if I run this, will it unroot my phone? Or will I just be able to flash a custom ROM via Fake Flash after?
Second question is - do I need to wipe any data before I run nandroid restore? I read somewhere (can't remember where) that there were SMS issues if you didn't? If so, what exactly should I wipe?
Final question - there seems to be differing opinions on what is the best set-up for the storage card format/partitions. Any recommendations on the 'correct' guide before I sort out Apps2SD?
Thanks in advance for your help

Bump.............!

Basically if you flash an unrooted stock rom, that is what you will have. A stock desire with no root.
What custom roms have you tried? Most should actually increase battery life.
No need to wipe anything before doing a nandroid restore. It's a bit like windows system restore. It replaces everything back to the way it was at the moment you did the backup.
As for A2SD, if you are using a 2.1 rom then you need an EXT partition on the SD card. Froyo or 2.2 roms don't need the EXT partition, but some now use it as most people don't like googles version of A2SD. An EXT partition of 512MB and the rest FAT32 is normally recommended.

Appreciate your reply - the unrooted Stock ROM = not rooted, makes sense to me now!
I'm running deFroST now and the battery usage is probably 50% higher... It seems to be the luck of the draw.
Thanks for info on no wipe needed and partitioning.
All the best.

[Q] a2sd or a2sd+ on rooted stock rom

Hi
I have not been on the desire forum for quite a while as i got an SG2 but a friend of mine needs some help with his HTC Desire.
He is realy frustrated with the memory running out all the time so
I am going to root it for him and try to get him sorted with the memory issues.
He will not require anything special so I basically want to root it and install a2sd or a2sd+ onto his stock rom if possible so as not to lose his apps etc.
My question is, is it possible to install a2sd or a2sd+ onto a rooted stock rom without losing any data?
I know i need to add an ext3 partition which is not a problem.

It is but its much more hassle than its worth. best bet would be to flash something like Teppic74's rooted stock 2.3.3 (or even 2.2 but Dont see why you would).
You probably wouldnt need to wipe for this anyway. This is assuming its a GSM (Sim card) phone.
You can always take a titanium backup of all the apps and data anyway incase you do have to root.

Look for A2SD+ in description.
Backup all apps/data with Titanium Backup before wiping.

thanks guys. just what i was looking for

flashing custom hboot without reflashing ROM?

as i'm not so much into these flashing stuff, here's a very simple question...
i wanted to flash a new hboot because the small data partition is rly annoying me, even with a2sd++
so only problem that i have is now, can i flash a new hboot that simple or do i have to reflash ROM, do a full wipe or something like that?
my desire is s-off @leedroid HD port, rooted for sure...
thanks for any answers

Make a complete nandroid backup, flash new hboot via fastboot, go back to recovery, wipe everything and restore backup.

so nandroid backup includes all app installations and settings, but not the partition table(hboot)? also, isnt it problematic to restore the backup into a new hboot, as the partition spaces have changed?
and another question: do i get problems if i have some apps moved to sd card with android system a2sd?

It will cause problems if your /system is bigger than /system on your new partition table. Which hboot you use now and which you plan on using?

Planning to S-OFF, some questions before I do

So, I'm planning to finally S-OFF, mainly for the extra internal storage, and the extra speed since I won't be needing my ext3 parition any longer, so just to get some things straight -
1) I am currently on the latest Oxygen ROM, is it OK to S-OFF with this ROM?
2) I've made a nandroid backup of my ROM for restore, thing is, once I re-partition without an sd-ext, what happens when restoring the nandroid? Because when restoring, it needs to restore sd-ext... What do I need to do?
Thanks

As far as I know, Oxygen has a built in a2sd enabled when it sees that you have an EXT partition and might mess up Alpharev's (and or Revolutionary's) S-off process accourding to their site. I suggest you flash CM7 rom temporarily then S-Off with this installed since natively it doesn't support A2SD.
I'm not sure about the 2nd question. My logic tells me that I leave the ext, and do a nandrestore because it will obviously look for an ext partition to flash the data files back. The problem is once, restored and rebooted I don't know if there is a command or zip file you can flash to undo the a2sd and transfer the data from the ext to the data partition of the phone.
It would be better to go do a fresh reinstall of the rom and use titanium backup to restore your apps back.

Thanks, I probably will do the long TB restore process.
Re. the ROM issue - Will flashing Leedroid 2.5.0 Froyo ROM be good enough? As it seems to be pretty stock-ish.

Quoting Alpharev.nl
Requirements:
The only requirement right now is that the ROM you're running is rooted.
As techniques such as 'data2ext' have been popping up, these might disturb our finely-tuned flashing process.
Please revert to a rooted stock ROM if possible. Your /data partition is used for temporary storage of important files.

For my understanding as long as the ROM doesn't use data2ext, or 'anything'2ext out of the box it's good to go. I've S-off with Cyanogenmod rom on my phone so I can only speak from what I experienced.

[Q] RevolutioN v4.0 Question Link2SD

Hi guys, im thinking to flash the RevolutioN v4.0 rom to my desire, just wanted some tips. Im currently on cm7 and its a decent rom but i want to experiance some sense now
I wanted to know, is it possible to use Link2SD on this rom? instead of data2sd?
Will all my titanium backups be restored fine from my cm7 rom?
I have 4ext recovery, i wanted to also know how do i clean my ext4 partition ONLY and NOT the rest of the SD car?
Thanks a lot in advance

To find out if Link2SD works, I recommend to search thread.
Restoring apps should not be a problem, as long as you do not restore any system-data. Only WiFi-Access-Points should work fine, because both Roms are based on Gingerbread.
4EXT-Recovery has under wipe-menu the option to wipe everything except SD card (FAT32-partition).

You can of course always make a nandroid and try it out.
