Hi guys,
New to xda.. I own a defy with 2.2.2 official SEA. I want to update to CM7 RC0, without losing the downgrade ability. After reading a lot in xda, I've got a fair amount of knowledge to flash my phone. Just have a couple of queries..
6) Can I restore my phone to send it to warranty after flashing CM7?
- You can in these two situations
1 - You have a full SBF of your original ROM (for carriers that already released 2.2 is very easy to find one)
2 - You have a nandroid backup AND a fixed SBF of the version you need.

Quick question:
Considering option 1, I have the official ROM (full sbf, 2.2.2 for India) downloaded here. If I flash to CM7, can I re-flash it with the official full sbf to claim warranty? Considering the scenario that I only have contacts and sms to restore and I don't want to restore settings, apps and all. I like to do them anew (even if it takes time).
Technically, that would be like formatting the drive which has the operating system, instead of restoring an image.. Is that possible? Is Nandroid Backup + fixed sbf is the only way to go back to the stock OS to claim warranty?
P.S. - I still don't get what fixed sbf is. Can anyone help?
Just create a backup of your current OS if anything happens restore it.

You mean Nandroid backup? Can i restore just that file (and not the sbf) in case anything goes wrong?
If your device is rooted download the 1.4.2 version of 2ndinit go into custom recovery and create a backup, then boot back up normally and connect device to the computer and copy the backup to a safe place on your computer, so if you ever need to back it up, you will have the file.

I mean do I always need an sbf file to restore an image?
No you only need sbf. file to flash a image, to restore and image all you need is a copy of a backup.
Hmm.. okay... Consider this scenario:
1. I'm having official 2.2.2 SEA ROM
2. I just want to root, install a custom recovery (take a backup in Nandroid), make changes to the current ROM and I'm NOT flashing a new ROM ie like CM7.
3. Can I just restore the backup from recovery if something goes wrong (without any sbf of course)?
4. Do I still have to install 2nd init in that case?
P.S. - Thanks to your patient replies bro.. Much appreciated
Yes you can downgrade back to sea version using sbf file
Just make a nandroid backup if anything goes wrong restore the nandroid you made plus flash it with the fixed or full sbf file of sea and it will bring everything back the way it was that's what i did anyway and it worked
Let me know how cm7 is on the SEA version if it works stable ill install it
Cheers

Yes 2ndinit is a custom recovery program as long as you have that you wont need sbf. Files. Sbf. Files are used with RSD lite in order to install custom roms. You can use any recovery program you want, best I have found to use on the defy is 1.4.2 version of 2ndinit.

Sure.. But in Quarx's thread, It was advised to flash Nordic ROM first before installing CM7.

I just restored my old nandroid and flashed with the fixed sbf but i believe if you do a full sbf it will result in the same thing both ways should work

Yes thats correct some people have installed over the SEA version and its full working im yet to test this i have however tested the NORDIC II version and flashed cm7 beta 6 and that did work nicely but i went back to SEA15 until cm7 releases a more bug free version.

What i found in the Official SEA 2.2.2 ROM's thread
ok make sure you do not install CM7 directly on this rom, else boot looping.
Please follow the cyanogenmod7 FAQ point 7. http://forum.xda-developers.com/show....php?t=1065798
i tried and was stuck on boot loop.
Again FLASHED this sea15 sbf via rsd lite back to square1 now need to start the process all again.

Nordic is the way to go it seems..
Nice find because i just got my sea15 back i listened to someone from here like a idiot they said they were running SEA15 with cm7 which is a lie because it when i installed cm7 i got a never ending boot loop so id like to say it does not work with sea15 it took me an 1hr to restore all my stuff back to the way it was so yes NORDIC I or II is the way to go thanks for the info
You're welcome mate.. Heard review that RC0 is way better than Beta6..
Finnaly the thread i've been looking for.
I'm currently on official German 2.2.2. I really want to try out CM7 but the tutorials keep telling me I need a sbf (wich is not available at this moment) of my version if I want to downgrade again.
So just to be sure:
Having a sbf is not an absolute must?
And in the case anything goes awry (eg. boot loop) I just have to restore it via my nandroid backup, unroot, deinstall 2ndInit, wipe and I'm practically back were I started, right?

That's correct. Even if you can't find a full sbf (carrier released version of your OS, usually a large file, 200-300 MB), make sure you have one nandroid backup of your data/settings and a fixed sbf (usually stripped down version, less size <50 MB) of your current OS. This would enable you to re-flash in case you have to claim warranty.
So just to be sure:
Having a sbf is not an absolute must?

I don't think so. You MUST have one if you want to claim warranty. Even if you don't need warranty, still you need either Nordic ROM or UK ROM (sbf files, mind you )to be flashed first to install CM7.. Other ROMs are not recommended.
And in the case anything goes awry (eg. boot loop) I just have to restore it via my nandroid backup, unroot, deinstall 2ndInit, wipe and I'm practically back were I started, right?

This only works If you flashed with nandroid + fixed sbf of the Nordic/UK ROM.
OR
You have the full sbf of your current ROM, which you can flash from RSD lite.
Hope this helps...
P.S. - Can anyone confirm these answers?
Aww, well i guess i'll be waiting for the sbf files then
Well, thank you anyway for the info.
Who releases this sbf files anyway? Are they somehow extracted out of offical update packages or are they leaked from service contractors?
I am also confused. I thought a nandroid was a complete image of the phone and didn't require an SBF?
Putting it in PC terms I considered a nandroid the equivilent to a ghost image of a HDD? So if I had a PC with XP on it and took a ghost image of that it would be a complete copy of the drive. I could then install Vista on that drive and when / if I wanted to restore the ghost image and it would restore XP onto that system?
I understood an SBF to be a system image as such, but not including the very base level stuff that a nandroid backup would have and hence why you can flash a 2.2.2 rom but need a 2.2 SBF flashed on the phone?
Or am i getting confused?

I think your German 2.2.2 ROM has been added only yesterday. Go to www.motorola.com/update, select your region - Select MOTODEFY - Follow instructions.. (Don't forget to do a hard reset after updating )
Full sbf s are released by the Manufacturers/Carriers. It's like untouched windows XP cd. You can directly update via MSU or use RSDlite to flash it..
Fixed sbf s can be made by anyone, maybe you or me, by making some tweaks, just like we do to Windows XP using nlite (which i'm still not that familiar with )

Please guide me in step by step manner...........I know how to root.....How to install sbf using rsd in bootloaser mode.........and open system in recovery both system and clockworkmod...............
have you just tried flash a stock 2.2 sbf via rsd?

3.set your rsd in option ,first come first service,then restart it
4.turn your defy into bootloader mode
5.connect your phone and pc via usb

7.now you have a stock 2.2,if you want a froyo leaked ,you need root your phone and do a reboot,then install clockworkmod ,i remeber it's a apk,then you open it after you install it, you can install clockworkmod ,before reboot into cwm,you need turn off usb adb.
can i finish it after i have my diner?
good works!
good works!
Wht s rsd n adb?
Nandrod+fixed sbf method
Flashing SBF directly with RSD lite will not not affect the phone, but affect your wanrraty, no official update in INDIA yet for froyo.
Better you follow nandrod+fixed sbf method.
1. Root your phone with Super one click.
2. Installed System recovery.
3. boot into system recovery and backup your system if you want.
4. Wipe DATA/CACHE/DALVIK CACHE.
5. Restore Nandroid backup of froyo of your choice which should be already copied to SD.
6. Go directly in the Boot loader after system restart by pressing Vol up button during restart.
7. Flashed Fixed SBF of corresponding froyo.
8. Let the system Reboot in foryo.
You can back to eclair any time with this method by direct flashing 2.59 SBF with RSD lite in case your need.
Why? Say that he bricks his phone, then his phone can not be retrieved even by Moto guys as even they use rsdlite so simply speaking they will never be able to figure what actually caused the phone to brick...

rsd lite is a software which is used by Motorola to flash firmware to a phone's memory.
ADB (Android Debug Bridge) is a tool that comes with the Android SDK that allows you to control and interface with your Android device. It is located in the tools folder when you unpack the SDK.

and what happen when we had some faulty part or so and then go to service????
Service people obviously check the software installed!!!!!!!
With locked bootloader there are very very few chances that you will brick DEFY. You have to be more fool than a fool to brick your defy!!!
OKAY
I used rsd ,used adb,used sbf and everything ..........i too bricked once and survived via rsd.........now well versed in these techs
No signal problem after froyo update....
I followed all instructions perfectly and got 2.2.2 uk stock rom working with its fixed sbf but i cannot get 2g network signal, but wen the restore to my original eclair firmware, I get full signal..
Please help me guys....
after flashing 2.2 put this file in sd card and flash it through recovery
http://www.mediafire.com/?k8dsbbq0ceodv86
I would recommend CM7 by Quarx
Much more faster than moto 2.2
z4root is not working for rooting, is it? mine is bought from India with the 2.59.0 update already given. the z4root app crashes after showing "acquiring root shell". and i've tried many times (even after rebooting), but the same thing happens. and any ideas when froyo will be out here officially? the motorola forum says late Q2 in Asia Pacific regions.
yay! SuperOneClick 1.7 does the trick. phone rooted. i hope it can be unrooted when needed.

So from what you said, here is the things which i dont get.
step 2: install the system recovery? can you please link me which one!
step 3: i guess after installing system recovery we can boot into system recovery, but how can we do that? And backup our system-> can you provide some more info on this?
step 4: Wipe DATA/CACHE/DALVIK CACHE is this the same thing we do while booting into the special boot menu while pressing the volume downbutton?
step 5: Please link any of the good nandroid back up file
step 6: when i have to do this? after restoring during the first restart?
step 7: Flashed Fixed SBF of corresponding froyo. link?
Thanks in advance for your effort!

You can get these all steps in sticky thread **** FAQ | Guides |Tutorials ****.
Anyway below are the steps with links:
1. Root With SuperOneclick (Reboot Required after this)
2. Download Tenfar recovery apk from here: http://forum.xda-developers.com/attachment.php?attachmentid=467632
3. Install this APK (save on your card and use browser to install) and open it and and click on Install Recovery system, will ask you superuser request, click allow. Wait till it installed.
4. Click Recovery Boot.
5. System will reboot into recovery.
6. Now with volume up/down buttons move to backup and restore.
7. Click power button to get into back and restore
8. Get into backup option in similar manner to backup your system.
9. It will start backing your files and after completing task return to menu.
10. Now back to your main menu and enter in click on Wipe data /factory reset and click yes, similary wipe cache partition.
11. Go to advance and click on clear dalvik cache (very imp from my point).
12. Now go back and click on backup and restore and restore your Nandroid backup (save your downloaded nandroid back in sdcard\goapkrev\backup before entering recovery)
13. After restoring backup click reboot the system, make sure that you press vol up immediately after pressing power button it, otherwise you will be in bootloop. Remove battery if necessary (don’t think you will need this)
14. This will make defy to boot in bootloader.
15. Now flash fixed sbf froyo with RSDLite. Let it complete the process, will take hardly 2 min. to write fixed system and will boot automatically
16. And you will be in Froyo (first will take a time to create dalvic cache)
Make sure that you have Motorola driver installed for your defy.
I am using 3.4.2_177-Nand.NORDIC_DEBLUR.zip (http://m.cfa.aero/nand/3.4.2_177-Nand.NORDIC_DEBLUR.zip) and 3.4.2_177-Fixed.NORDIC_DEBLUR.sbf (http://m.cfa.aero/fsbf/3.4.2_177-Fixed.NORDIC_DEBLUR.sbf) fixed sbf file which I think are latest.
Original file for 2.59 is at http://and-developers.com/sbf:defy from India section.
This is also helpful when you plan to move CM7.
Cheers…Happy flashing
Yep, I did a foolish thing (got too excited with the Froyo update), I did the update via MSU, but I did not even do a full background check on the pros and cons of this particular update (I have the latest). After experiencing very minimal problems with this update, I realized that I could have been better off with the stock eclair. After reading some threads here, I found that you could go back, provided that you did other update methods (nandroid, sbf, I don't really understand much.. I'm a noob! What can you expect?? LOL)...
so is there a chance that I could go back to the stock eclair? I'm from the Philippines.
Thanks!
yeah you can go on eclair. by nandroid+fixed sbf method..
Prerequisites downloads
nandroid folder and fixed sbf of your eclair rom
rsd lite 4.9
motorola drivers (or install motorola phone tools v5)
first root your froyo rom via super one click
install 2nd init (follow all the instr. on FAQ on CM7)
keep nandroid file (if available of your eclair in /clockworkmod/backup on your sd card.)
boot into 2nd init and then recovery>custom recovery.
wipe all data and cache..even go in advanced and wip davlik cache.
now restore the nandroid form back up and restore options.
after that reboot ...keep holding vol up key to get the bootloader mode...
attach via usb and run rsd lite 4.9 ( install all the req. motorola drivers first.)
and then flash the fixed sbf of the same (what you nandroided) eclair rom.

hi! thanks for the replies guys!
@SeaFargo it's not that I don't want to.. It's just that I don't have much time in my hands these past few days. Hey, I've searched your guide, and you have the 3.4.2-177... thing is, my build is the 3.4.3-36-1.7, and I'm from the Philippines (my build is the SEA upgrade).
The Froyo's getting stable in my phone sometimes, but there are a few times when it gets a little hot and becomes slow. I've never experienced that with the Eclair. That's why I'm thinking of downgrading, or at least have a copy of the downgrade files. Oh, and hopefully it doesn't mess up the warranty, my defy's only a month old.

I got your flow, thanks. I'm new to the technicals of these processes, and so I'm still trying to understand fully what is to be done and how it's done.
But, the thing is, I've done upgrade to Froyo without even doing backups. (Yeah, stupid me.) Can I still go back to the stock Eclair?
Yes you can
You will need to download a nandroid back-up and fixed sbf of eclair. You can find it here: http://forum.xda-developers.com/wiki/index.php?title=Motorola_Defy#ROMS_.26_Recoveries
Download the one you like and use the method already described in this thread.
Hmm. Thanks! Another thing, it's required to root the phone? Wouldn't it affect the warranty? I'd like to keep the warranty for one year. Phone's still new.
gt 2.1 as pre isntalled on my defy and upgraded to 2.2 with Motorola software 2 months back.
and now rooted my defy and plans to install to cm7 to experience its power.

1. is this right or anythng more than what i understood.
2. can i upgrade from Original Stock froyo in india to Cm7 2.3 .
3. CM7 is a complete OS. so it wont matter what ROM u curerntly have if its upgradation .
4. do i need a nandroid backup to install Cm7. as far i understood i need a nandroid backup only if i downgrade to Stock os and want my setting and apps back in phone.
5. is there cm7 2.3 country specfic. where will i get a fixed-cm7 version so that i can downgrade to stock froyo later.
6. Do i need to backup my current OS ???
hopes someone will clear these doubts .. seems reading lot will also make u confused ... someone do have any other good link of upgradation tutorial .. ?? plz share that ...
Thanks in advance and sorry for my non formal english ...

Ok it's pretty simple. Do following.
1.> Root the device using 2ndInit
2.> Create nanodroid backup
3.> Make sure you turn off USB Debugging
4.> Reboot to enter Bootmenu (Press Volu+ when you get blue light)
5.> go to Custom Recovery> backup and restore> Backup. This will take sometime.
6.> Choose Wipe data/Factory Reset (you will lose all data, apps etc)
7.> Select Wipe cache partition and then go to Advanced > Wipe Delvik Cache
8.> Go back and then select install zip from sdcard > choose zip from sdcard
9.> Then select the Zip from the SD card and say Yes
Wait for sometime, reboot and you're done.
After this is done, you can user gapps.zip to install the google applications.
thanks to the post @mandhir.
You need froyo 2.2 in order to upgrade to CM7. Since CM7 uses the same Froyo kernel you can downgrade any time you want. A nandroid backup is adviced incase you arent impressed with the changes and want your phone back in the previous state.

That's exactly what a nandroid backup is.
Sent from my ME525+ using Tapatalk
method 1 was deviced at the time when there's no official froyo available, and it's now outdated. it was for you to upgrade from eclair to fixed froyo sbf since cm7 requires froyo. just ignore that since you already have official froyo in your phone.
you will also come across some old posts mentioned doing a nandroid backup of eclair and flashing a fixed froyo before cm7 incase you need to downgrade back to eclair for warranty purposes. that's out of date too since you can now do that with official froyo.
so just start from method 2 and you'll be right. and make sure you run defy basebandswitcher in the app page to select the correct baseband for your phone/carrier. this very important step is missing in the instructions unfortunately, and caused me some frustrations and nearly given up on cm7
edit: if you have a lot of apps in your phone now and want to port them into cm7, do a backup using apps like titanium backup etc. it's different from nandroid backup which is like an image clone of your current phone state.
@ryan thanks. nw i understood thing more clearly .. cm7 requires froyo kernel. Bt somepost i read to use an Froyo Ceee jordan version (i dnt remeber the term completely
) if u cant upgrade succesfully to cm7 from ur stick froyo .. I hopes it wont happen to me ..
@jh20 thanks a lot man . i nw it clear like water for me . seems i shuld have checked the posted date along with reading those old ones..
i had a misunderstading that titanium is used to take nanndroid backup and from there all the doubts started ..
im posting what i understood
Titanium backp will only contain apps and user settings which cant be used to directly flash as ROM . it used to restore the data to phone after installing or reseting the same OS on which backup is made.
While nanndroid backup is an image of the existing OS with all the uset settings and app so u can restore it anytime . this will be helpfull f cm7 is nt satisfying ur need..

is cm7 for defy is a Full-sbf or fixed SBF ?? . I wish to have a downgradabilty feature if cm7 2.3 wont work fine and i can switch back to stock froyo .. where will i get a fixed SBF of Cm7. all the post contains a zip file without specfying its fixed or Full. shuld i take care anythng special for a downgradable option ..

they are all fixed sbf.
(edit: actually i think they are nandroid backups and not fixed sbf, sorry)
those that are not downgradable will be mentioned specifically in their first post.
i've nandroid backups of cm7, miui, and stock froyo. i can switch between them anytime i want, just like clone image backups of my pc
btw i think they should have called it "patched" sbf instead, as "fixed" can be confusing. when i first saw it i thought it meant the rom is fixed and can't be altered/downgraded which is just the opposite of what it's supposed to mean
A fixed SBF is flashed in order to provide the missing kernel in a rom( and other stuff). But since you're already on a froyo kernel you wont need it, as CM7 requires the same. It is it proposed to use a Nordic froyo as base for better performance but you can use any official froyo as base to upgrade to CM7.

@ryan thanks friend.it was de direct answer. i thought the "fixed" wont have those two partitions which store version number so that they wont be formated and overwritten and thus keep downgradabilty .( gt this from defy guide @ xda ) .. didnt thought abt the kernel part ..
so now i feel its easy than it seems to be if i can switch between os with the nandroid backup . my defy has now 1 gb free . dat it it took total 1gb with app an OS. how much space nandroid will it take .. im using an 8gb card. and i have all apps backup. (not settings).
and how u feel cm7 .. doest it made any bug to u . i dnt have feel any bug at my froyo 2.2.2???
im planing to use this link RC1.5 Here:http://www.multiupload.com/217FS9PYDC from http://forum.xda-developers.com/showpost.php?p=13279140&postcount=1
is that ok for me ??
once again thanks all ..
i don't use any extra apps and my stock froyo nandroid backup is 357mb with all the motoblur stuff, while cm7 110909 nightly is 226mb. so the size depends on how many apps and data you have i guessed.
Ok .. nw in india we dnt have Moto Blur .and apps take only 200mb (nw free memory is 1000mb showing) as free memory for user is 1200 on factory reset.
another term that came to my mind is "nightly" what it actually means.. I thinks it a custamised form of stable cm7 .. r8 ? can u post some screenshots on defy .. i cant find anysuch thing ..
no, nightly as the name suggested is a nightly updated version. that's right, they work on the rom just about every day! and the daily updated rom file is updated to the jordan-cm7_nightly folder:
http://defy.tanguy.tk/
once a nightly rom is good enough it will be uploaded to the jordan-nightly folder. that's why the jordan-nightly folder has less files than the jordan-cm7_nightly folder.
so if you want to be safe, you should use only nightly roms from the nightly folder. cm7-nightly folder is for the brave as some of them may not be stable or still has known/unfixed bugs. infact i know for the fact the 110912 rom was pulled from the list because it did not work. and notice that there are some nights missing too for some reason
then once they are satisfied that a rom is good enough to be a major release, it becomes the rc, like rc0, rc1 and rc1.5.

That's not true.
Fixed SBF means the Code Group 39 and 31 has been removed from the SBF so it wont flash upper CG versions, and therefore killing your downgrade ability.
You need to use a Nandroid backup after a Fixed SBF is to provide the corresponding Files that "should have been flashed" by the CG39/31.
You cannot change the Kernel, that's locked by Motorola, and we are just using Modules attached to the official Moto Kernel. but nothing more sadly.
And dont worry about bricking your phone, is almost impossible unless you disconnect your phone on a critical point/remove battery while flashing with RSD Lite, like creating partitions or something like that.
The worst that can happen is getting stuck past Boot up logo, which means you just have to start again and flash with RSD
You can restore your nandroid and get back on froyo whenever you wanna throw it into the warranty. Dont worry theres not an option to brick the phone and it isn't that easy anyway. Remember to only wipe data/cache through custom recovery , never use the stock recovery and you should be fine.

So i installed CM 7.1 i think from rom manager but it wouldn't go past the boot logo with the skating droid. so i took battery out and went to recovery mode and i think i accidentally restored one of my Motorola Droid data and now my phone wont go past the Google CM boot logo i think I'm screwed any suggestions? please help. i guess I'm a noob and sorry if there was something similar to this posted already i just can't find the answer to my problem thank you.

was running perfect until i accidentally restore the wrong data
oh and yes I've tried data wipe not working
Do you happen to have a nandroid backup of your stock rom you've had before ?
A nandroid backup is what you should have created using CWM recovery. Just restore it with CWM.
You don't have a nandroid backup ?
Flash the full SBF of your original stock rom (the one you had before flashing cm7). This should be a 2.2 Froyo whatever rom. Connect defy to pc, open rsd lite, start the phone and enter the bootloader and flash the sbf using rsd lite.
Have you installed Froyo (2.2) before going to Cm7? If not (you still had Eclair 2.1) then this is the problem.
However, get 2.2 on that phone and flash cm7 again following this guide http://forum.xda-developers.com/showthread.php?t=1054447
Instructions for some of these steps can be found here: http://forum.xda-developers.com/showthread.php?t=1216982
Also, be patient! When the phone boots for the first time after a flash that may take a while!
Try wiping data cache partition and Dalvik cache from the custom recovery..

hello sir,
i am facing the same problem with my defy. want to know have you got any solution to that. i am having nandroid backup of my froyo rom. but how to install it with CWR when the phone is not even go beyond bootscreen. i am not much familiar with android. its my first android cell. please help me sir.
waiting for ur reply
are u getting any errors while booting up?
My Defy+ had originally an Android 2.3.4
I successfully flashed many ROMs and happy with CM7 WhiteRabbit.
I decided to restore a nandroid backup of the original firmware 4.5.1-134_DFP-89 just to test if I could go back "just in case".
With great wonder the phone is stuck un Motorola logo even if checksum seems right.
If I re-flash WhiteRabbit the phone boots correctly.
I never flashed a kernel different from the original.
I know I could flash a more recent SBF but could you help me in explaining how is this possbile?
PS: I wiped cache/data/dalvik with no result.

Some roms like cm7.1 stable contain kernels, ie boot images chances are you've flashed a boot.img(kernel) without knowing
teamwork makes the dream work
You are right! Now the next (and last) questions.
Can I go back to old firmware without sbf?
How can I discover which ROM flashed the kernel?

Without knowing the rom you've flashed I can't tell you which have caused it, but if you still have the zips then just open them up the one with the boot.img done it,
Only way back is reflash the sbf unless you made a back up of the boot image when you made your nandroid
teamwork makes the dream work
The nandroid backup I am trying to restore has a boot.img. When I find which ROM flashed the kernel I will compare and see if it is the right one. Thanks.
EDIT: I found out that I flashed a kernel with maniac's CM7.2 RC1 (I thought it was no kernel like nightlies), but it is different from the one I have in stock image backup. So the question why I am stuck if I restore the nandroid including the kernel remains. I will go on in the study.
