[Q]URGENT !!!!! downgrading failed

WHat i did was:
-restore 2.2 nandroid backup
-flashed 2.2 fixed sbf so i could keep downgradability...
Now when i tried to go back to 2.1 eclair version 2.21
-i flashed 2.21 blur full sbf
and now i have black screen as if downgrading wasn't possible...
What options do i have ?

NO HELP? am i the only one with this problem here?
ANother question i had if there's a way of downgrading kernel? because i've experimented this. On kernel 2.6.29, the multi touch works fine but on kernel 2.6.32, multi touch is buggy, way buggy...

I'm guessing your stuck on 3x roms. So your going to need to see if you can reflash the fixed rom and try downgrading again.
If not that fixed rom wasn't fixed.

Thanks for THE reply...so now what i can do is flash full sbf (3.4.2.145) which is same version as my earliest fixed sbf, restore nand backup of 2.2 then flash the FIXED sbf CEE one (3.4.2.155) and then try downgrading? would this work?
EDIT: Walter79's sbf's are messed up..i used his fixed sbf version...didn't try CEE one tho

Did you find a solution to downgrading i to did the same thing.

errrm...
righto after reading that post again, i've had to change this :| I have had a similar problem myself, but i did manage to resolve it with 2 nights after work of swearing, redbull binges and many failed attempts :| I finally somehow managed to get Pays-ROM to load :| hope you get it sorted though

Im on a fixed sbf again..but my prob is to go back to 2.1
I hv restored 2.2 nand nd flashed 2.2 fixed cee rom..if i flash a full 2.1 sbf..wud it work?

From what I know, if you have flashed 2.51 or higher full sbf (non fixed) then you cannot go back down to 2.21.
However if you have flashed 2.51 or higher with the system and CDT code groups removed (i.e. fixed SBF), then you should be able to go back to 2.21 just by flashing the complete 2.21 sbf.
DO NOT flash a full sbf 3.4.2.145, because that will upgrade the CGs that prevent downgrade.

What if i flashed 3.4.2-145 (full sbf) and then restored 2.2 froyo nand and then flashed a 3.4.2-155 fixed SBF, now if i flash a full 2.1 sbf, would it work?

No, because once you flash any FULL sbf that is greater than 2.21 then you flash the parts of the ROM that are non-downgradeable. Once those partitons have been flashed then you cannot downgrade. That is why the FIXED sbf's should have those partitions removed.

For your information, the detailed investigation around these non-downgradeble code groups is in this thread:
http://forum.xda-developers.com/showthread.php?t=945035
Some very useful information in there, and they summarise that once you flash Version 2 Code Groups, you cannot go back down to Version 1 code groups.

Well, i did flash a fixed version of 2.2 sbf and then flashed 2.1 full sbf but that didn't work out and the screen went black...so i flashed 3.4.2-145 full so that atleast i could use my phone but it was a deblur version and i have no contacts...can't import contacts from sim either...so i just want to go back to 2.1 and then give my phone back to motorola...isn't there ANY way to remove those CG's off the rom you're on at the moment`?

as far as anyone here understands it, NO Can't be done

Defy to Bravo
Has anyone tried and tested the Defy ROMS (such as PaYs or JBoogie's) on the Motorola Bravo (MB520)?
I would really like to take the plunge, but I've read Bravo users have bricked trying Defy ROMS?

Just dumb to try one phone's firmware on anothers. It is just like installing mac software onto windows

I believe the only to go back to 2.1 is to restore the nandroid backup of 2.1.
there are a few thread posting stock nandroid backup of 2.1 (except it's already rooted).
you have to flash also bootonly sbf based on the same version.
then you can manually remove superuser.apk and su manually using adb shell.

Did someone acutally used this method and was succesful? I have downloaded a stock nandroid and the related bootonly sbf. Furthermore i have the related full sbf file if i need it.
So you think its probably possible to put the nandroid on the sdcard, go to clockwork, wipe everything and then restore the nandroid. Afterwards i think it would be the best to remove the battery, put it back in and boot directly into the bootloader and from there flash the bootonly via rsdlite.
Im kind of scared to give it a try. What if something goes wrong? Can i go back to my last 3.4.x ROM?

I've done this on 3.4.2.xxx version (full sbf flashed). What happens is that it goes to M screen and then reboot, then goes to M screen and reboots...this goes on and on but i haven't tried flashing bootonly. I don't know what can happen if i flash that but what i know is that you atleast DONT get a black screen, it does show M logo...

my phone came with 2.54 preinstalled i understand i cant get to 2.21. the question is, if i flash full sbf (not fixed) of 3.4.2 , can i get back to my stock 2.54?
thanks!
edit:
after some research, i will lose downgrade-ability. smg versions of 3.4.2 are +1 higher than my 2.54

[Q] Downgrade to original

I flashed froyo on my new defy 2.51 to Pays-ROM Defy v5.0 which is based on 3.4.3-11. It says my kernel version is 2.6.32.9.
I want to downgrade my phone to the original stock rom, to get my warranty back. Should I just flash it to the 2.51 eclair stock with rsd lite? or will that brick my phone?

It depends on whether you flashed a fixed SBF or not. If you flashed a fixed SBF of Android 2.2 (3.4.3-11) than you can flash a full SBF of Android 2.1 to your phone (look for it at the forum) and your phone will be alright. If you flashed a full Android 2.2 (3.4.3-11) SBF than it's not possible to get back to your stock rom (Android 2.1).

There's something I'd like to know about this, even if you go back to 2.1 for warranty, can the warranty guys still know you modded it?

What is the difference between fixed and full sbf ? How do I get to know which one I have?
I followed the steps on this post -
[ROM] Pays-ROM Defy v5.1 Froyo with Ginger feeling
This is what i followed --- :s
README - Step by step flashing guide:
You can go to step 5 if you already flashed 3.4.3-11 SBF, rooted and installed clockwork recovery or have ROM v5.0 or higher.
Don't wipe after you flashed the SPF or the ROM. Also no wipe is needed before or after a ROM update. But wipe before flashing a new SBF!
1.) Wipe your phone in recovery mode
2.) Flash 3.4.3-11 Motorola SBF with RSD Lite in bootloader mode
(The sbf is packed in a archive just extract it and then you get the sbf.)
3.) Enable ADB in the settings and root your device with SuperOneClickRoot for Froyo. Then do a reboot.
4.) Disable ADB and install clockwork recovery image
5.) Put the ROM.zip to your SD Root and boot into clockwork recovery
6.) Flash the ZIP + reboot and enjoy

@LeoD7K
I don't believe they can see which rom you've flashed in the past so you'll be save if you revert to your old rom. (Someone on this forum told me that)
@pragund
I'm not sure whether this is a fixed SBF, you should ask the developer who started the thread. Another way to find out whether it's fixed is to check the file size. A fixed SBF is very small, around 15-40 MB whereas a full SBF is around 300 MB. So if you still have the SBF file you flashed you can check the file size. Also you have to make sure you've never flashed another full SBF before. So if this was your only upgrade and it's a fixed SBF you can downgrade back to Android 2.1.

my sbf file size was 360mb!
Is there any other way to get to an original stock rom? so as to get warranty?

Well the only option left is to check whether your carrier has released an official 2.2 update. If that's the case you could update to that and still claim your warranty as it's an official rom. Every carrier should release an official Android 2.2 rom at some time so if it's not released by your carrier yet it should be just a matter of time. Aside from that there are no other options to get your warranty back. But also I'm not sure if you can update from one Android 2.2 to another Android 2.2.

I bought it outright unlocked in india ... do I get a direct update from motorola?

[Q]noob question before upgrade to CM7

Before i start to flash CM7 ROM ... i had a question which i could find a concrete answer in other threads or the FAQs :
I'm on Defy US t-mobile 2.2.1 Froyo,
Can I get back to this for warranty by just flashing using the original SBF??
Or do i have root first and take a nandroid backup??
please adivce.

I come from original US Tmobile firmware also. There is no sbf for the official 34.4.9 system as it was an OTA update! HOWEVER you CAN EASILY flash back to 2.1 eclair system 3.6.360 using sbf and simply do the OTA update. Don't worry about a thing they all have (even official US Tmobile eclair) cg version=4. So there are no issues down-grading. Just don't flash the newest leaked Gingerbread 2.3.4 as it has a cg version=5 and can't be down-graded. So the CONCRETE ANSWER IS YES YOU CAN DOWNGRADE FROM CM7 BACK TO OFFICIAL 3.6.360(2.1.1) USING SBF AND THEN APPLY THE OTA UPDATE FOR 34.4.9(2.2.1)

[Q] serval question for JORDN_U3_97.21.51

Well... it's a long story.
I bought my China Retail Defy ME525 this May, accidentally flashed 3.4.2-155 deblur as stock rom. Two day before I accidentally flashed JORDN_U3_97.21.51 (again ).
Now I stuck there and unable to flash any other roms in RSDlite. I'm trying to update it to froyo and later restore my CM7 backup.
Here's my questions:
According to here, it is possible to get an OTA update. But did anyone actually make that?
Would ME525 be unable to get T-Mobile update due to its IMEI?
(This is a silly one, however I really don't find the answer). How could it be possible to install an nandroid backup after flashing a fixed sbf? my led never turn blue after I flashed the sbf. Cannot enter bootmenu PS: The fixed sbf is based on 3.4.2-107 TMobile US full sbf)
Is it possible to make up a update.zip that acts as installing nandroid backup?
Would it be the same to install a nandroid backup first and later flash fixed sbf?

you install the nandroid backup first and then flash the sbf...

JORDN_U3_97.21.51 is an eclair sbf which contains CG39.smg and CG31.smg ver=5. You can no longer flash ANY froyo sbf. In fact the only sbf you can flash now are 2.3.4 and 2.3.6 sbf and of course JORDN_U3_97.21.51. 2.3.6 sbf is ver=6 and has no know downgrade possibility. Follow this guide to get back to froyo http://forum.xda-developers.com/showpost.php?p=14762402&postcount=143
Keep in mind that this is a "dirty" method of getting back to froyo and you are ALWAYS stuck on ver=5. What that means is that even after getting to froyo using this guide you are NOT free to flash any sbf you like. You can however, use this guide to get to froyo and install cm7 from there

100% Stable Defy+ SBF

Which version do I need in order to revive my phone? Which version do I have to install to get the DUTCH language.
http://sbf.droid-developers.org/umts_jordanplus/list.php
taken from here
Is this an original Motorola stock OEM version of Gingerbread taken from the Motorola team? Is it 100% stable? Containing working 3g 2g wifi no reboots and all the original stuff. Is this rootabel? I bought my defy plus unlocked/simlock free and it's only a month old!

First question : wich version you have on your phone ?
About the DEFYPLUS_U3_4.5.1-134_DFP-139 roms: Yes they are 100% stable and full blur (OEM Motorola SBF)
Language (version RTFR) : Deutsh, English, Espanol, Français, Italiano, Nederlands
Root : SuperOneClick 2.3.3

2.3.4. But I'm stuck at a bootloop and can't fix it with a factory reset.
Retail France, Retail Germany or Retail Spain version?
I have the chance to send it back for repair (warranty) but it will take approx. 8 weeks before it is fixed.
But then again.. if the Motorola repair service does the same trick.. I can do it too right?

Version RTFR = Retail France
Try maybe to find a full SBF of your rom (google) before, because this roms are not downgradable to 2.3.4 if warranty needed.
Did you try a wipe data/system wipe cache by the recovery? (Power on/volume-
simultanously and volume+/volume- when you are on the android and triangle)
Of course you can do it (flash with RSDLite), but as I said forgot about warranty after!

But the 2.3.4 roms on here are tweaked (like bright buttons etc.) and not stock delivered by moto.

Internet and google aren't limited on XDA ! ...;-)
Settings - about the phone - system version. Copy the name and google it, who knows...
Good luck

Bootloop here. Searched alot, 2.3.4 german retail version nowhere to be found. I guess I have to send it to repair service.

Didn't find a full SBF of your original rom : 4.5.1-134 DFP 74 Retail DE
But here is a nandroid backup of this rom
http://www.multiupload.com/4VMC4XVIVZ
Unzip and flash with CWM backup (But search how to do)
PS : Walter79 used it for MSginger!

I have to thank you for searching a rom for me. But I'm stuck with a bootloop. can't fix it with boot recovery + the last time the phone worked debugging was turned off. Therefore nandroid is a no go.

An idea (coz ur ph have already a problem with warranty :send it to moto broken, rooted and maybe CWM inside ;-O) so why don't flashing this one http://forum.xda-developers.com/showthread.php?t=1116522 (or another 2.3.4 full SBF) and flash the nandroid backup on ?

Is it possible to download this sbf rom and flash my device with it and then download the nandroid backup you mentioned earlier and then flash it again?

Yes you can flash this full SBF (its 2.3.4 GB / CG=5 as your original rom) with RSDLite. Root the phone, install 2ndinit. Flash the nandroid backup with CWM (full restore data-sytem + advanced boot + devtree)...

I actually planned to bring it to repair tomorrow morning... but now..
There's a chance Motorola is going to put 2.3.6 on it. And if I'm right I will not be able to downgrade ever again. Right? But then again.. I'll be sure it is 100% stable.
Now.. your trick gives me 2.3.4 + all the other stuff. But not stable.
really hard decision

Just had a look on the nandroid backup. It is not complete (no devtree inside) so if you make the modif you'll have and hybrid rom (md5 and system of nandroid and devtree from the full SBF 2.3.4).
If you flash an official rom on 2.3.6 you cannot downgrade to 2.3.4 but it's just a problem of warranty. After why downgrade you'll have the last generation of defy+, ready for ICS...
If you want save the warranty only one option : bring it to repair in motorola store.

So just to be sure. This sbf file is a complete version of gb? And will I be able to upgrade to 2.3.6 afterwards?

Yes but flash the SBF with RSDLite not the nandroid from this thread.
About the downgrade/upgrade :
Froyo CG = 4
GB 2.3.4 CG = 5
GB 2.3.6 CG = 6
When you upgrade an SBF : Froyo (CG = 4) to GB 2.3.4 (CG = 5), GB 2.3.4 to GB 2.3.6 (CG = 6) every time you do that you burn an eFuse (bridge) who doesn't allow you to downgrade. So impossible to downgrade GB 2.3.6 to GB 2.3.4 and Froyo or GB 2.3.4 to Froyo.
So, since you stay on the same CG you can always return to stock (Need the full SBF or a nandroid backup of your stock rom). You can also always upgrade (CG =5 to CG =6) but no downgrade (return to CG = 5) after that.
Don't know if it's clear ;-))

Flashed it with this one! Everything works great again! Thanks for your help
