Hello dear Community,
I'm using CM for quiete a while now and read many posts in different forums, but unfortunately I still couldn't find a satisfactory explanation which "systems" are running on my Defy+.
More specifically:
I installed a BL7 stock ROM update after I bought my Defy+. Then I waited some weeks until there was a way to root this via a CN Rooted SBF and installed CM9/10.
I now want to know if there is still data associated to that stock ROM left on my Defy+, or whether it was all overwritten by the CM10 ROM
Might any remains of the CN stock ROM be responsible for problems with connectivity / Should I install everything again with the EU Rooted SBF?
I feel puzzled about all the layers of systems on the Defy... theres a SBF, firmware, kernel, 2ndInit, 2ndBoot, CM, ...
How do these all these depend/contain/build up on each other? (i.e. does CM10 with 2ndboot contain its own kernel/firmware?)
I hope you understood my questions
Thank you in advance.
Components of stock rom should have nothing to do with the connectivity problem.
Just think of it this way, sbfs to you are irrelevant because you're on bl7. Basically, cm10 wipes system(stock Rom), and you wipe the data and cache, so there's nothing really left(except for the stock kernel). The exploit we use to run custom kernel bypasses the stock kernel and uses kexec to load another kernel on top of it.
2ndinit is what we use to run custom recovery and control the initialization of the custom roms by use of modules, such as to enable overclocking.
2ndboot basically uses kexec and loads the custom kernel(as in cm10 and the in development cm10.1).

I was wondering if I could flash this (UK version) Defy+ MB526 Firmware on a MB525 (red lens) without any problem?
Could someone be so kind as to share a little knowledge here?
Thanks in advance.
I flashed this full sbf and now no 3g and no market, trying to downgrade, hope to find and answer.
I dont think there is a downgrade after you flash full-sbf. we can only use cm9 and GB kernel roms after that.

you can not do that. Defy and Defy+ have locked bootloader that wont allow the downgrade. Still there is hope for your phone, your issues are quite solvable. You should root your phone, install baseband switcher for 3g, then install custom recovery and then flash google apps, all of this you can find it in the dev section.
If you ask there I would gladly help
u can flash ms2ginger, argentstone, CM7, CM9 but to install there u must root your phone, custom recovery...
Hello,
I have installed CM7 for Defy(not plus) in my cellphone perfectly.
So then, I found the CM7 Defy+ nightlys and I'm trying to install it. But when I install the ROM on it and reboot, it stays in the initial logo forever.
Could you help me?
Best regards.
please help
Try another rom, like MUIU or any other rom and see if the start loop is overcome.
Did you wipe the memory after?
If you want to instal defy+ nighties, you first have to flash the gingerbread kernel. (CM9kernel.zip)
So now flash the stock ROM and start again. You probably downgraded to instal three normal defy nightly do you have to flash a defy+ ROM with the same bl nr. After that root instal 2nt... and flash the defy+ nightly (and wipe). If you want to be able to switch, you will have to flash the downgrade sbf again and flash the CM9 kernel. Then you can switch with just flashing the kernel and ROM (sbf wipe)

Do cm7 nightly have these fixes? I'm running nightly now and camera seems ok, but I don't know yet about the battery.
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
So i just bought a defy+ and it has 2.3.5. Stupid carrier.
Well, im trying to find which baseband is using but its not listed in the about phone menu. Is there any other way around?
I want to install a custom rom with 720p, but all there are so many different kernels i have no idea which one to use, or if i even need to flash one. My previous phone was a Xperia X8, you just had to unlock BL, flash kernel and flash rom. Here, theres the SBF files , the nandroid stuff. Are you supposed to use both?
If anyone can recommend me a rom thats not MIUI(i need my drawer ok) or ICS, i would appreciated.
Anyway, i need to know the baseband to see if i can try the soft simunlock.
Here is my build number :4.5.2-51_DFL-50 whatever it means.
ps: i already made a backup with cwm of the stock rom and also rooted my phone.
To flash a sbf you have to download RSD Lite and drivers, here u have the steps: http://forum.xda-developers.com/showthread.php?t=966537. Then, install the rom u like from recovery. Here u have all Epsylon and Quarx ICS nightlys (ICS, CM9) http://forum.xda-developers.com/showthread.php?t=1432100. With Defy+ use gb Kernel.
I just have some questions regarding the kernels. If i install the ICS roms and then i want to go back, which kernel i need to flash to be able to restore my phone using the nandroid backup i made.

None, because when you are doing full backup a copy of a kernel is included.
Then im going to update CWM, make a new backup just in case and start to play a around a bit.
Thanks for the help ^^
ps: is there anything wrong with 2.3.5? just asking because i hardly see any posts related to this android version

2.3.5 is perfectly fine! It's what I use as a base for both CM7.2 and CM9 builds for Gingerbread and it's great! It's rootable and you can even flash down to Froyo if you wish so, there's a special version 6 Froyo sbf in the forums.
If you have any doubts or if anything confuses you, please do ask before trying, that will save you both time and nerves
Full 2.3.5 sbf that I use: http://sbf.droid-developers.org/umt...22_A022_M002_HWp3_WIG148094_Service1FF.sbf.gz
*EDIT* Just read the whole first post You can use Quarx's CM7.2 and CM9 defy+ nightlies on your phone without flashing anything else but the ROM zip and gapps zip (optional, as you know). Both available here - http://quarx2k.ru/
i have one more question regard the defy+,
If i flash the cm7.2 or cm9 builds by Quarx and want to go back, i just need to restore the backup i made with cwm right? or do i really need to get the sbf from my carrier?
is there any difference(flashing a sbf or restoring form nandroid. Not in procedure but in the final result)?

Yep restoring the backup will suffice but if you want to get back your warranty you need to uninstall CWM and any other root apps and unroot your phone. That won't leave any trace of root.
Following are some main differences in flashing nandroid and SBF:
1.) Nandroid backup restores your phone to exact state as it was during backup. SBF gives you back exactly how your phone was when you purchased it. Thus, you still have root and CWM after nandroid whereas your phone is clean as new after SBF(recomended to claim warranty).
2.) SBF flashes almost everything except data partition! Nandroid flashes even the data partition..
Thanks for the help, ill use nandroid until i get back. Besides cwm is easy to remove.

I have a question, I have a stock defy (Bayer, according logcat)..
The android version that it has is 2.2.1 and build version is 3.4.2-107_JDNL-9..
Once I root it and install CWM, can I just flash any rom, like the one you link above or I need to use RSD lite for something before?
I'm sorry for the noob questions but never had a motorola before, always nexus line which has unlocked bootloader..

Yep once you have CWM you can go on with flashing ROMs with ease. You need RSD lite and SBBF only if you soft brick your phone(Very hard!) or want to go back to stock to claim warranty.
Thank you for your help

Hi folks!
As the title suggests, I want out from JellyBean and back to MIUI Pickachu Edition 2.xz
I think the latest 2nd boot builds have the GB kernel since I see 4 Vsel levels, so should I flash the froyo kernel?
If so, what should be the order of flashing ROM -> Kernel or other way round?
Also, I have a nandroid backup of when I had MIUI. What steps do I have to follow to restore it, i.e, do I have to flash the ROM (and/or kernel since I was on froyo kernel when the backup was taken) to restore nandroid?
I read a lot about the fuss of latest nightlies changing /system and /data to ext4, but in my case they are ext3, so I guess I should be alright?
Reason for going back is LAG! the immense amount of time to open stuff. I tried loving it, but its just too slow to the point I feel like its running Windows 8 on Intel 8086.
Please post all questions in Q&A. Thread moved there.
Hi!
My friend was in same situation and he went ahead and tried to flash MIUI Pickachu edition, but his process got stuck and now his Defy won't boot.
Hes now flashing stock Froyo sbf.
Thats the reason why I need to know instructions to get back to MIUI without going through sbf flashing.
Any help gladly appreciated!

You need to flash a Froyo SBF. For some reasons going back to 2.3 always ends in a cache error, flashing 2.6 kernel, nandroid, fullwhipe etc. doesnt work

R U on Froyo or GB? if Froyo try to flash fixed sbf I will attached if needed.
Just flashing froyo kernel was ok for the 2nd boot builds upto 9 nov builds.
From 9th nov builds the cm10 rom formats our defy to ext4 file system, so in order to downgrade we need to flash the sbf.

My friend, thats what I have said, in my OP,
I have checked using mount command from rooted shell and I can confirm that my /data and /system are STILL in ext3 even though some say that the latest nightlies change the fs while formatting.
Try restoring your backup, you may succeed, otherwise you need to start all over again, with the sbf. I find it better to start all over anyway, no matter, what rom we are talking about. Those installed over a freshly flashed sbf proved to be snappier and absolutely bugfree - at least for me.
Simply try to restore your backup. I tried many roms so far, aslo the newest by Quarx and Epsylon and i always worked for me to install a new rom/zip/ withour anything further. Never installed a sbf.
Was quite late in posting a reply but I did end up flashing Stock Defy 2.2.2 SEA sbf.
I did flash successfully MIUI (Pikachu edition) but it was a bit off, so took a backup and flashed sbf.
Have been on stock ever since (been kinda busy).
