Dear All,
I am currently running Defy with stock FROYO and thinking of installing CM7.2.
My question: Will I be able to downgrade back to stock FROYO if I want to?
Hady
sure c8
go to clockworkmod recovery -- advanced -- backup -- backup all, so when you want to go back just retore the backup or.. you can download a froyo sbf and flash it via rsd lite, and then you got it , have froyo again in your defy

does it matter what base firmware your on when flashing the stock nandroid backup found on the dev thread? like if im on gingerbread will restoring that 2.2.1 backup work or cause a brick? I had a samsung vibrant before, and when i restored a backup from a different version of android firmware it bricked and i had to use a pc software to flash factory firmware. anyone went from cm7 back to stock? also in the thread it says you have to flash a recovery image again.

You have to use the correct recovery image. YES. 2.x images will only work with 2.2 ROMs and 3.0.0.5 will only work with 2.3 ROMs. However there is 3.0.0.6 that will work with both 2.3 and 2.2 ROMS. I have links in my signature for that recovery image. I would highly suggest flashing that recovery image prior to flashing back to 2.2.x.
Hi
I flashed the new ICS experimental build and i like so far...but i am not sure now if i am able to switch back to cm7 if i want to since there is osmething with the kernel.
Does Quarx use the 2.3.4 (should be reverseable) or the 2.3.6 Kernel (cant go back from this one)
I like to use the new ics testversion but in case i need to use camera it would be nice to go back..
Is it possible? If so..just flash cm 7 or any tricks needed?

Re-installing CM7 Stable (e.g. 11.11.11) should definitely work.
If you took a nandroid before you installed ICS then you should be able to go back by restoring your backup. You need to restore boot and devtree also.
backup & recovery -> restore (which will restore system and data)
then do advanced restore and restore boot and devtree.
I flash the 11-11-11 version by quarx and after it starts reboot into recovery and restore my backup. if you have any problem try wipe dalvik
will flashing a full sbf of 2.2.2 work?
you can flash a zip with the boot.img and DEVTREE.IMG.have fun.
so i cant just flash CM 7 stable? never done anything nandroid...only flashed *.zips
just flashed ,today i flash ics,but i reflashed 2hour latter because i can read the relations .
I flashed ICS 7-12 today. I was able to go back to Cyanogenmod's official nightly 7.1 build 63 after wiping the data. I'm using the froyo kernel.

just wipe data flash .zip of cm7 then wipe dalvik and after it turns on go into recovery again and restore your backup. Maybe you can try to do all in one boot but i think it is risky
I am currently on a stock Android 2.1-update1 TMobile US ROM on my Defy (green lens) ROM. I would like to try out CyanogenMod 7.1 (or 7.2 RC) and need help confirming my understanding of the process. I am already rooted and have installed the GoAPK recovery.
1. I need to flash my kernel to froyo to 2.2. In order to be able to downgrade back to 2.1 I need to use a "fixed" sbf. If I run the smgver.exe utility on the sbf file and it says "no version found" than this is a safe sbf to flash (can still downgrade).
2. Before I flash this new kernel I need to (should) do a full nandroid backup of my current rom so I can restore it if things go wrong. I might need to install SuperOneClickFor2.x to do the backup and future recoveries.
3. Once I flash one of these "fixed" sbf I can then do the "update.zip" process to flash CM7 onto my defy. I will need to do a factory reset and wipe the data/cache partitions. This will cause me to lose my contacts/calendar/etc AND my installed applications (and their data, so I need to back them up using something like TitaniumBackup).
4. Once I've got CM7 (with froyo kernel) I can flash one of the CM9 builds for the defy green lens that is built specifically for the froyo kernel
I've searched and read as much as I can, I feel like I "got it" but I just wanted a little confirmation before I start hacking this phone apart =)
Thanks for any help you can give me =)
Here is the explanation from all that I know:
1. I need to flash my kernel to froyo to 2.2. In order to be able to downgrade back to 2.1 I need to use a "fixed" sbf. If I run the smgver.exe utility on the sbf file and it says "no version found" than this is a safe sbf to flash (can still downgrade). Ya, that is true. But after flashing fixed SBF you also need Nandroid backup to be restored.(This is not your nandroid backup. Its the nandroid backup supplied with the fixed sbf)
2. Before I flash this new kernel I need to (should) do a full nandroid backup of my current rom so I can restore it if things go wrong. I might need to install SuperOneClickFor2.x to do the backup and future recoveries.
Yes Nandroid backup is always recommended. Superoneclick is a software needed to root your phone. That answers the rest.
3. Once I flash one of these "fixed" sbf I can then do the "update.zip" process to flash CM7 onto my defy. I will need to do a factory reset and wipe the data/cache partitions. This will cause me to lose my contacts/calendar/etc AND my installed applications (and their data, so I need to back them up using something like TitaniumBackup).
Yes, however its not update.zip but its <ROM NAME>.zip Your contacts,calender can be backed up in your google account and if you use gapps(google apps. Needs to be installed separately by install .zip in CM) in your CM those will come again. Your installed apps and data yes can be restored from TB. You can backup SMS using SMS backup+
4. Once I've got CM7 (with froyo kernel) I can flash one of the CM9 builds for the defy green lens that is built specifically for the froyo kernel
Yes either that or you can even directly flash CM9 for Froyo kernel.
Hope that helps...
It's there a way to remove manually ClockWorkMod (2nd-init) from stock rom?
Besides, erase bootmenu folder, what more i have to do?
if you want to stay on stok Rom, reset the mobile data
of course you can back up apps first
Well, my intention it's a little more complicated... I want to create a custom sbf following instructions from Vaserbanix thread in order to have a 2.2.2 sbf from my original system. In some pages, i get an original sbf from my carrier but it's a 2.2.1 version... My phone came with a 2.2.2 version, so i made a nandroid backup, then i extracted system but i realized that my system it's already rooted and with bootmenu included. So, i want to make it more "stock"
Solved. Please, moderator...close this thread....
Hi,
I have Defy+ running quarx's CM10 android 4.1.2.
What I want is to recover my phone as it was, with official gingerbread and no 2nd init or other software installed on it.
Is there any way to do that?
If yes I would appreciate some help with it.
Thanks!
That's quite easy, isn't it? Simply download one of the offical bilds (sbf files), copy it (i mean if needed thing you need for flash like safe wipe) on sd card, wipe everything, boot into stock recovery (well i believe dl-mode) and flash official rom.
I was thinking about doing that and thanks for confirming it. What I am not sure about is if everything else installed that does not run in android, like 2nd init and other stuff lets call them , pre os, get deleted and only the stock firmware will be left. I will do this though and we will see how it goes.
Now do any of you helpful people have an sbf for Europe without blur UI in it?
A link would be helpful if so.
Thanks again!
Sbf cannot be flashed from sdcard! It must be done thru RSDLite. 2ndinit, etc will get wiped. If stuck in a boot loop after flashing, wipe data after stock recovery

Quite simple. Wipe Data / Cache first via Stock Motorola Recovery. Flash SBF for your region. Voila! your phone is all stock again.
If you want a good De-Blur ROM try WIUI or if you still dont want the customizations move to MS2Ginger ->
