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.

I never saw an answer to this question. But I did see someone say that they went back to 2.1 after they were running the new leaked 2.2 ROM. I also recall reading somewhere that once the new radio is updated, you can't go back.
If I am currently running Froyo 2.2 with version 2 radio, can I just RUU, then run Unrevoked to restore root, and then restore my nand backup to go back to were I was before I started, which was Eclair 2.1 rooted with v1 radio???
No speculation please. I want to know if this is possible. Preferably from a dev or someone who has done this successfully.
Thanks in advance!
You're making this way too complex (RUU, etc.). Just nandroid back and you're good.
Will nandroid also downgrade the radio??

The OP stated that he wanted to go back to V1 of the radio. So if a nandroid restore won't downgrade the radio, then what options are there?
I believe this is what you are looking for.

My question is... if you do this Froyo 2.2 as in the developement area, because your phone is rooted when you are done, I don't think you will be able to get any further updates until you un-root. So do we have to revert all the way back to 2.1 or radio version 1?
I think I'll wait.

No, the OP stated that he'd "heard somewhere" that he needed to go back to V1 of the radio. I said he was making it too complex, just nandroid restore.
Really, it's that simple.
I forgot to nandroid after unrooting and installing the 2.1 ota leak. I am now rooted with the 2.1 ota leak and flashed the froyo leak. How would I go about getting back to stock?
So if we had previous 2.1 nandroid backups we can just restrore those? (while leaving the new HBOOT and radio of course)
I just want to be clear.
Hello
Im new to posting, but not new to the forums. I read this forums daily. I would like to take this time to say thank you to the whole community, I personally have benefited from all the custom roms and tutorials.
I have a question:
I was on 2.1 rooted and decided I was going to unlock my nand and get Fresh Evo rooted 2.2 rom (which is amazing by the way) so I did a NAND backup before starting the process of unlocking my nand and flashing the Fresh 2.2 evo rom. Now that I am on the 2.2 Fresh Evo rom I would like to restore my 2.1 nand backup to take a look at some important data on there, after restoring that backup can I come back to a backed up nand of 2.2 Fresh Evo rooted rom without having any problems?
Simply, can I go from 2.2 rooted to a NAND backup of 2.1 rooted stock, then come back to my 2.2 FreshEvo rom?
I appreciate the help!
Thanks

EDIT:
<--- NOOB AS WELL
Yes you can. I keep a Nandroid of Rooted 2.1 Stock, Rooted 2.2 Stock, and my latest CM6 Nightly that works handy at all times.
Thanks!
So just simple restores will do it when switching? No need for cache wipes or anything?
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
Hi!
I'm a newbie on defy. I just installed jboogie3 2.0 rom in my defy, but im thinking in changing it 'cause it's gave me problems with battery draining really fast.... so, im thinking to put cm7 on my defy, but i want to know if it possible to downgrade to stock froyo if something goes wrong.
((sorry for my english))
Thanks!
As far as i know, JBoogie is to be installed via nandroid backup and then you have to flash a fixed sbf.
If you have followed this way, you can downgrade to froyo by flashing a full sbf or always a nandroid + fixed sbf if you are still keeping downgrade ability to Eclair ( useless imho ).
Beware, if you have flashed a full sbf GingerBread leaked rom there's no way to go back to froyo, nor eclair.
when you say a fixed sbf, would the one linked to in the guide, here:
http://forum.xda-developers.com/showthread.php?t=1054447
be a fixed sbf, or is it another one?
That's a full sbf, not a fixed.
Anyways is a froyo one, so you won't have any problems in downgrading.
Thnx, everyone! Now i have installed cm7 on my poweful defy
hey all
i was after a little help,i am currently running the official uk 2.2 rom on my T-mob Defy.Now T-mob has released the official 2.2 i would like to put that on my defy so i can make a nandroid backup incase of warranty issues,my question is how do i get my phone back to a stock state (from 2.2uk to 2.1 t-mob)so i can download the update as a backup?
thanks for your help
scottie
or point me to a thread where i can download a fixed t-mob 2.51.sbf as ive been reading and reading and reading...but getting nowhere....please a little help!
Hi Scottie
Both the t-mobile 2.21 and 2.51 sbf files are available here:
http://and-developers.com/sbf:defy
Don't forget that if you want to keep downgradability, you need to flash a 'fixed' 2.2 rom plus the system nandroid.
Rgds,
Kash.
thanks for the pointer,so...i want to get back to 2.51,i have my backup of original,so do i just flash the 2.51 rom then restore my backup?or have i missed something ?
You have Froyo with Full sbf installed?
Then you can not directly downgrade to Eclair 2.1!!
You need a Nandbackup from a 2.51 Eclair Rom, and a Fixed 2.51 SBF.
If you have this, then reboot into Recovery, do a Fullwipe and restore the 2.51 Nandbackup.
After this, reboot directly into the Bootloader Mode (hold the Vol+ Button), and flash via RSD Lite the fixed 2.51 SBF.
thanks for the help...got fed up with buggering around and installed cm7 instead..its awesome!!
