[Q] How to downgrade from CM9 to stock ROM? - Defy Q&A, Help & Troubleshooting

Hi
I have defy+ (MB526) Red lens.
I upgraded from stock ROM Android 2.3.6 to CM9 (4.0.4) Jordan nightly 13.6.2012.
New android works great but it has one HUGE annoying bug - battery wont charge more than 4.15V and it used to be 4.35V.
I was reading and I know it bugs exists for many people and there is no solution I tried 2 different battery patches and it didnt work.
So now I want to go back to CWM backup that I did on official ROM (nand backup). But I heard it could be a problem because now i got newer kernel?!
Those are the details I have now:
CM9 Nightly jordan 13.6.2012 Android 4.0.4:
Baseband version:
EPU93_U_00.59.01
Kernel version:
2.6.32.9-gbdd614e
[email protected] #1
----------------------------
And this was my stock Android before upgrade to CM9:
Stock Android 2.3.6:
Baseband version:
EPU93_U_00.60.03
Kernel version:
2.6.32.9-ge281b6e
[email protected] #1
Build:
4.5.1-134_DFP-231
----------------------------
So my question is can I use nand recovery to go back to my stock android backup that i have. (full system backup)?
Thanx

Download the SBF file and flash it with RSD lite

Are you sure I cant restore NAND backup? As far as I can see, both versions use same GB kernel 2.6.32.9-xxxxx
Thanx

[Q] How to restore CM7 to Froyo

Hey everyone.
I have a Red Lens Defy running CM7 and I want to restore it back to the offical Froyo, with no trace of having rooted/installed a ROM, for sending it back to T-Mobile for a repair. (UK T-Mobile)
About phone:
Model number: MB525
Android version: 2.3.5
Baseband Version: EPU93_U_00.59.01
Kernel Version: [email protected] #1
CPU info: ARMv7 Processor rev 2 (v71)
Mem info (avail/total): 155 MB / 477 MB
Mod version: CyanogenMod-7.1.0-RC1.5-jordan
Build number: Gingerbread GRJ90
Instructions would be helpful. Please and thank you
P.S If I could do this with a nandroid backup then unroot and remove the recovery mode(?), could you link please? (the one on this thread: http://forum.xda-developers.com/showthread.php?t=880813&page=7) doesn't work, the download has been removed, I have searched!)
Hi,
Good news, you can restore your phone back to froyo. But for that you need to flash the full SBF of your original rom.
Did you save it in CWM recovery backup ? Coz we need the exact information about your original rom to find it on Internet...
Maybe you can try this one http://forum.xda-developers.com/showthread.php?t=1178243
Flash the full Sbf (not the nandroid) with rsdlite
Can guarantee it will come back with soc module, they changed that the first time mine went for repair.....

It must work, froyo kernel has soc devices support
Motorola Defy CM7 RC 1.5 OC 1GHz

Help please!!

Hi all. I stupidly upgraded my firmware to 2.3.6 and obviously the camera no longer works. I believe I have a green lens cam (SOC module) so I tried greenbreadmod but that didnt work. I tried flashing CM7.2 but got stuck at a static red M logo. I had to use RSD lite to flash the sbf again. I see lots of links to possible fixes and patches but which one works? Can anyone give me a step by step guide to fix it if at all possible? Here's my phone info:
Systen version: 45.0.1320.MB526.O2.en.DE
Model number:
MB526
Android version:
2.3.6
Baseband version:

Thank you in advance

No solution at this time. You must wait for a nightly of Defy+ CM7 who manage the green lens...

How do I install from the link please? Never done it with seperate md5sum

first install bootmenu, then wipe and flash the package it. Green lens will not be available till Quarx got development.
You have to wait for a nightly of Defy+ CM7
I flashed mine today. I guess i have red lens(because my camera is working). I didn't know there was a risk for loosing camera function. Guess i was lucky.

Before you install the zip file, try to wipe cache and dalvik first. Efter installing the zip try to boot. If still it does not work, try to wipe data he reboot again.

Hi everyone. My SM-G7102 came with the following:
Android version:
4.3
Baseband version:
G7102XXUAML5
Kernel version:

I have flashed cwm based custom recovery and rooted using SuperUser 2.02. Everything is working fine.
[ Earlier, I had tried, Twrp and Philz recoveries, but they just gave me blank screen and reboots to system.]
I did a full nandroid backup today using my working cwm based recovery, on External SD Card directly.
I want to try out VANDROID ROM V1 by vandroid699. It says it is "E2 Stock Based ROM". My guess is that this is compatible with my device and its Jellybean 4.3.
I am also aware of the fact that once I upgrade the android version on my device, there is NO DOWNGRADING WITHOUT BRICKING THE DEVICE.
Please anyone confirm:
1. Is it OKAY to go for the Vandroid ROM V1 without having any problems?
2. Will I be able to do a "Nandroid Restore" if something bad happens?
3. I have also downloaded from Samsung update website this file "G7102XXUANE2_G7102OJVANE1_PAK.zip". It contains the Tar.Md5 file which is Odin-flashable.
Is it the RIGHT STOCK ROM FOR MY DEVICE? [btw, I am from Pakistan]
Thanks in advance
N.B: I have experience with Nexus 10, Nexus 7 2013, HTC HD2, in terms of flashing roms, kernels, nandroids, but I am new to Grand 2!

Well its just an E2 stock rom flashable zip nothing extra like s5 apps or anything just Samsung bloatware removed ( i haven't tried it ) ...if u want another rom try Gennxt Rom by ballibro and yes the nandroid backup will restore everything and you can flash the firmware you mentioned ...
