I am going to root my desire and was wondering about nandroid backup. Does it do a backup of my stock rooted rom AND radio or just the rom.
I´m thinking because if I try a custom rom I have to use the specific radio for that rom. And if I then go back to my stock rooted rom with my nandroid backup maybe it needs the "stock" radio...
Nandroid backups everything but ro make sure get Titanium back up free from android market

there are no 'specific' radio's for different roms, only if you use any froyo roms will you will need to update the radio to a higher version compared to stock.
If you want to revert to stock you can choose to either keep the updated radio or flash an older version.
thanks for answers

I rooted my desire with unrevoked a while back, used alpharev to get s-off then flashed oxygen rom with data2ext then added on top.
I want to go back to the stock rom, for which I have a nandroid backup taken after originally rooting. Can I simply use clockwork recovery to restore? Will I still have s-off and can I reflash data2ext back on top of the restored backup?
First you need to change back to the bravo 1.5 partition layout. Then you should be able to restore the nandroid, you won't lose S-off. No idea if data2whatever is gone work.
Technically you don't have to change the MTD as this will be reset when you flash the RUU. Best to do it in case, though

The way I read his post he does not want to run a RUU but just nandroid back to a stock rom. Then you do need to change back other wise the nandroid won't fit.

Thanks for your comments so far - can you explain (or give me a suitable link) that explains what I need to do to 'change back'?
Never mind,I thought you flashed the oxygen hboot, which you didn't. You can just restore the nandroid.

Currently I am on Uk 2.21 2.1 rom and I want to upgrade to the new leaked UK 2.2 rom.
But actually I am happy with my rom because it is quite stable. So if I upgrade to 2.2 is there any way to go back and why? What about I build a backup for the Rom in advance and restore it later?
Thanks.
Hey before you flash uk rom 2.51 you shout do a nandroid backup because if you flash 2.51 you couldn't go back to 2.21 by flashing a sbf file. You only could root 2.51 with superoneclick and restore your old nandroid backup of 2.21.
Just follow the guide on Development forum. Got the uk 2.2 rom working yesterday, played around a little bit and are now back on 2.21 stock again and just restored a nandroid backup, nothing has changed. No prob.

Hi,
I have a UK unbranded Desire HD, 2.3.3 stock rom installed, however it is the official version that was leaked ahead of the UK release. Before upgrading to this ROM I did the downgrade process and while I was there I did the Radio and ENG S-offs. I also have root and have confirmed this using the terminal emulator.
My question is - Do I have to re-downgrade to a stock ROM lower than 1.7 to flash a custom ROM or is that done to get Radio and ENG S-off?
Also - When flashing a new radio, as one is recommended for the custom ROM I'm thinking of trying (Virtuous Unity), do I need to back up the original radio, or keep a note of what version it is with my nand backups? or is already backed up when I do the nand backup? This is in case I wanted to return to stock at some point in the future.
Any help is appreciated,
Cheers,
Grim.
If you already have root and s-off i would assume that there is no reason to downgrade again. As far as i am aware radio is not backed up by a nand backup so be best to take note of what radio you have.
Hit thanks if it helped

Thanks Ricey!
I've taken a note of the Baseband version in the settings-->about phone section which I think is the radio version ?
I'm about to try it now so wish me luck!

Hmmm, I didn't took note about radio used before flashing new ROM, but I have original ROM backed up. Now I have to find out somebody who have the same device not rooted and take a note about radio, right? that will be a problem, but not impossible... At least, I have NAND of original ROM
Flahing an original RUU also flashes the stock radio so wouldn't worry about it too much

Great, I was not aware about this. Thanks for clearing this for me
Thanks guys,
I'm now rocking Virtuous Unity 1.27 and it works a treat!
I haven't bothered flashing a radio, and won't unless I notice some issue, so far calls, wifi and mobile internet all work fine!
Also something weird did happen during the process - I did a titanium backup of all my apps and copied them off the sd card to my pc, then formatted the card (on the phone).
I then set about wiping the phone in the way described in the tutorial I read (using a zip called full wipe in the clockwork recovery)
After flashing the new custom ROM I booted up my beautiful new ROM, went through the initial setup only to find some of my old apps still on the phone!?
Noting in the Virtuous thread that a full wipe is REQUIRED, I thought, ok I'll wipe again and re-flash.
I did so, but this time I wiped through Clockwork (there's an option when you flash the rom through this app).
Same again! some old apps remained.
I then tried again, wiping using the technique in the video on the RCMix page (unmounting certain options in clockwork recovery screen).
Same again!
I carried on with the old apps still there, though have since uninstalled them for good measure.
Also, when I restored from the Titanium backup it annoyingly didn't link them back up with the market - I believe this is possible, but only with the paid version of Titanium.
If I hit any issues I'll let you know
Just a note about flashing radios. You may wan't to flash the recommended radio (pretty much the same for all ROMs these days) basically due to the fact that the chefs built their ROMs around that radio, and they know the optimisations are built for that one.
I have noticed some realy significance in battery drain when using an unmatched Radio when i thought i knew better than the Chef.
But gratz on your new ROM hope you enjoy being one of the free
Thanks for pointing that out wbbigdave, I wouldn't have taken that into consideration. I'll have a look at flashing the recommended radio tonight.
Cheers,
Grim.

Hi, here's some answers for you: for the radio, there is a thread of all the radio available for desire HD, so you don't have to worry about backup for your current radio.
http://forum.xda-developers.com/showthread.php?t=877295
Yes, backup can be done in cwm recovery and restore later on.
Wipe is necessary when it is stated in the instruction provided in the rom. Normally full wipe is a must when changing roms and are optional if up/downgrading version.
It is recommended to use matching radio with rom. Unmatch radio will cause performance drop of wifi, battery life etc.
All rooting, flashing are reversible. Just check the stickies in Desire HD Android Dev section on how to instruction.
Just make sure you have radio-off to change radio, s-off for flashing, and root to do all those above.

Make sure you back up your original rom (stock) incase you do need warranty and keep it somewhere safe.
I think everything else was covered

If i do full wipe does it delete the backup that i made ?
and how do i backup my apps,contacts,photos?
What is MD5?
Ok i understand how to flash radio.img now how do i backup my radio(the one i use now)?
Thanks you.
Hiya people!
Would it be pointless in installing the latest RUU, relocking and installning, then go back to unlocking the phone and restoring your latest nandroid backup that is based on a RUU earlier than the latest one?
I'm thinking that you're getting the new radio, hboot and such but lose the ROM specific updates, right?
Or, since our beloved developers are working so hard and pretty much all the time, should one just wait for the ROM you're using to get updated until you do install this specific RUU?
I hope that this made sense..
