Back to FroYo?

Hello can anyone help me? Im on stock FroYo and wanted to install other gingerbread based custom roms .. So suppose before flashing cyanogenmod 7 I did a full nandroid backup of my FroYo and flashed gingerbread then would I be able to revert back to FroYo by just restoring the FroYo nandroid or i'll have to flash a full sbf?
And if restoring will do.. can anyone tell me how?
Thank you in advance ... newbie here :]

flash back a sbf will do

Help needed - flashed GB defy

I was running a red lens defy running CM7.1.
I made a nandroid backup then then upgraded to CM9 and flashed the GB kernel.
I found CM9 too slow so booted into CWM and tried to restore my nandroid backup,unaware I also had to restore the kernel etc. from the advanced menu.
I understand I now need a SBF to restore my phone before I can root, install cwm and get to my nandroid backup.
Do I need a gingerbread SBF to do this? I tried a froyo one but it hangs on the moto logo.
All help appreciated!

You no longer have boot menu and cwm?
Do not flash any GB one. You can just go back to your original froyo version by flashing full sbf. For the list of sbfs check the thread from Walter79 in sticky threads of development section.

The gingerbread kernel u used on the defy isn't the same as the one on the defy + stock firmware.The kernel u used on the defy is a fixed sbf which is an original gingerbread sbf but with some modifications that allow you to downgrade to froyo.Normally if you recieve an official update from froyo to gingerbread on your phone you will never be able to downgrade.What fixed sbfs does is preserve ur downgradeability and are made from official sbfs and compiled by xda devs.
So in your case,since you have a defy,i would suggest you to flash with a stock sbf,the froyo one,ie the last official update your motorola came with.you can find that in xda forums.If not reply back with your country and carrier and i will help you

[Q] Can't flash regional sbf(only chinese)

Hi all i have a defy plus which came preloaded with 2.3.4 Asia Pacific android. I then rooted and installed CWM via 2ndInit to use MIUI Pikachu Edition. But due to the battery issue(< 84%) i tried to nandroid back to the stock. However, it failed and then i mistakenly flashed the chinese 2.3.6 sbf:
DFPRC_U_4.5.3-109_DPP-14-17_SIGNED_USADEFYPRCB1B50AA00A.0R_JRDNGIBRRTGC_P027_A024_HWp3a_Service1FF.sbf from this page: http://sbf.droid-developers.org/umts_jordanplus/list.php
Now, everything is working but the rom is unrootable and for the life of me i cannot flash ANY other sbf(tried the same page). Is there any other way to revert back(i have 2 nandroid backups of the stock firmware and miui, but i cannot root my rom via superoneclick to install CWM) without going to the service centre. Pls help!! Thanks

[Q] how to downgrade my defy to original

Hello PPL,
I've upgraded my defy to cyanogem 7.1.0.11 but I have no backup of my original rom, now my earpiece is cracked and I need to downgrade my defy so I can send it to RMA.
Everywhere I looked says that I should use my backup to recover my phone, but I have no backup.
Would you guys please help me.
I guess I should flash a new SBF into the phone, is there any repository I should look for?
I think I need a retail 2.2, where can I find it? Is there anyway to make sure that this file will be compatible with my defy?

The sbf list is a sticky in d Dec section....download ur sbf and flash it with Rsd lite....the usual works.....
Stock recovery>wipe data
Bootloader>flash sbf
Stock recovery>wipe data and reboot...
Even if u had a backup and restored it(I assume using Cwm).....u would still be rooted...and u would have to unroot it .....flashing sbf is easier but riskier..

Use the sbf of your country/operator

[Q] change rom??? possible?

hello,
recently i've made a restore of a system in my defy and then the phone went to black screen and bootloop and what ever, then i've tried to flash all the sbf that possible untiill i've installed one that my phone is worked with:
its details:
system details:
45.0.2311.MB526.O2.en.DE
android:
2.3.6
baseband :
EPU93_00.60.03
kernel:
2.3.32.9-ge2281b6e
[email protected] # 1
build:
4.5.1-134_DFP-2311
as i remember this is a defy+ SBF FILE
and my phone i think is a regular defy
but all the regular defy roms does not work!!!!!
now my question is how can i root my phone or which sbf i can flash to fix this?

this is 4.5.1-134_DFP-2311 O2 Edition Original ROM
did u flash this or planing to flash?
if u got bootloop after SBF you need to Wipe Dalvik, Cache and Data in stock recovery...

Unfortunately for you... You have flashed a BL7 sbf meaning you can't not downgrade to froyo and you can't install any other SBF with a Bootloader version lower than 7
The only work to root is through this method http://forum.xda-developers.com/showthread.php?t=1542956

You can't directly flash a older sbf like before you can all flash BL7 sbfs but I think you can go back to an older rom/sbf by flashing a fixed sbf or restoring a nandroid backup but am not 100% on that....

I had this problem myself. My thread is here and my solution post is here.
Good luck
