I install CM7.2 and CM9 (both GB kernel ) on my milestone2 .but when 2nd boot CM9 ,it shows "encryption unsuccessful ",and i'm sure i had wipe data and cache and dalivk.

any advice please ?
[Defy General] crakeron:
Encryption? :/ Have you activated device encryption?

Does CM7 work? If yes:

Try wiping data + cache + dalvik in CM9 recovery

And what kernel are you running? I'm guessing Froyo?

Thanks to your wonderful post.

Successfully installed dual boot and then ICS.

working like charm.

The only issue I am facing now is, Even after rooting, I can't use baseband switcher.

Error: You need Root permission to use this program.
[Defy General] crakeron:
Glad it worked :)

Have you got Superuser app and binaries updated correctly? I never heard of that before... Sure you're rooted too? And Defybaseband switcher is not automatically denied in superuser?

Ask around on the CM9 threads ;)

Buy the way, are you on a froyo or gingerbread kernel? (For statistics ;) )

[Defy General] mandhir.s.bajwa:
Yes Got Superuser and updated binaries. somehow Superuser denied access to Baseband switcher, and after about 2 reboots, I was able to manually change the permission in Superuser. Now it's working like it should.

btw: I'm on Froyo kernel.

Hi crakeron, I noticed that the telephone's network in the second boot does not work, when i go into the telephone's info baseband version is unknown.

You must use basebandswitcher to select your carrier's baseband ;).

And just check too that the APNs are correct (and settings, etc)

MultiBoot using GB Kernel + AOSP ROMs

Did you meant that MultiBoot using GB Kernel + AOSP ROMs is possible without BaseBand issue?

There are a lot of people who already try (including me) and the result was always the same "BaseBand: Unkown".

Some other threads talk about do not use AOSP as 2boot when you are on GB kernel, like MSGinger. But in my case it didn't boot.

Thanks for this thread anyway.

---------- Post added at 03:53 PM ---------- Previous post was at 03:45 PM ----------

I got this same issue using GB kernel in my Defy (red lens). I dunno how, but I think in somehow is a kernel related issue.

Multiboot on Froyo kernel is almost perfect, but keep up to date your main ROM data backup. Sometimes both ROMs get mixed :D

Continuous Bootloop on the CM9 defy 15th feb nightly only!!

Hi ..

I was using CM7 and CM9 dual boot .. I had installed the nightly build og 4th feb which was fine .. but I flashed the latest nightly build of 15th feb ..

just got dual boot running with cm 7.1 and cm9. Runs perfectly :D Cheers guys!

Just wondering though, when I finally decide to switch to cm9 full time can I make a backup of the 2nd boot version and move it to primary boot or do I have to start from scratch?

I'm still a bit of a noob at this!
[Defy General] crakeron:
At the moment, when you do a nandroid backup of your 2nd-boot rom, backing up /data fails so no :/.Maybe in the future it will work, but you can allways use titanium backup in the market, that works ;)

Hi, I`m kind of new here, but couldn`t find anything similar...

I`m running CM7.1 on my Defy working perfectly, and now I`m dual-booting with CM9, the version from 26 Feb.

The problem is that I can`t make any calls, I can receive calls and text messages. For example, when I try to make a call it just ends instantanealy (Call Ended), and when I try to enter a code to check my credits (pre-paid phone) I get "Connection problem or invalid MMI code.", but i`m pretty shure the code is correct.

Baseband seems to be the right one for my carrier, can anyone help me?

Thanks in advance.
[Defy General] crakeron:
Try wiping data on the latest recovery (the one for CM9), maybe check your apns? I don't like the 26feb build, it has problems so i'm staying on the 24th one.

Can you press vol down on blue led and access the bootmenu?

If yes see if you can wipe cache + dalvik on both roms. Can you get to boot into any rom? 2nd init? 2nd boot? Try and restore a nandroid backup you made before starting (i hope you did, i recommended it ^^)

It seems it's a bug due to multinoot, maybe you did it incorrectly or you're unlucky :/.

Don't worry for sure, as a last solution it will be easy to flash sbf + restore a nandroid backup ;). Try what i said first, you may make your way out without a sbf flash

btw what to do wen dere is a new nightly available for cm7 or 9 ???? how to install the new nightly release ??
[Defy General] crakeron:
Install CM9 (2nd ROM) normally, like you just did (you might not need to wipe data, simply cache +dalvik).

If you update your normal rom, all you have to do is re-zip-flash multiboot ;).

Sent from my 1Ghz CM7 + CM9 Defy
[Defy General] Omya:
so if cm9 nightly is available i have to follow all the steps again :confused:
[Defy General] antukubo:
Nope.

If upgrading virtual (I supposed it is CM9), just flash the CM9 Nightlies zip (not mutiboot.zip). Wipe cache + dalvik is advised.

But if upgrading your primary (aka CM7), you need to do the whole process again, which is flashing the multiboot zip.

Hope this will clear you mate... :)

Possibility to install dualboot for stock kernel on Defy+

Guys,

Is it possible to install a dualboot for stock kernel, so i will have a stock and CM9?

Thanks in advance
[Defy General] crakeron:
It should work ;). Backup first though.

Note: all kernels are stock. They're released by Motorola and we can not change them due to the locked bootloader.

Two kernels exist:

- Froyo kernel

- Gingerbread kernel.

So if you're on stock froyo then use CM9 for froyo kernel (eppy's and quarx's)

CM7 + CM9 double boot
[Defy General] biozshock:
Tried to get a dualboot. No success.

What was done:

Root

Install CWM

Reboot

Go to recovery then select cusom recovery

Select a zip file defy_multiboot_v0.4 from 1st post and install

Reboot

Put images from 1st post unser /fsimages

Reboot

Select cusom recovery again and install CM9-ICS-MR1-120305-jordan.zip

Wipe cache, wipe dalvik

Reboot and select "2nd boot" in CWM

After that i have loading screen with CM9 android robot on a skate but it never loads (waited about 15 minutes or so)

Tried dualboot from http://xdaforums.com/showpost.php?p=23399230&postcount=398 have no success.

Also it wipes motoblur data from stock ROM.

BTW. I have a Defy+ with (seems latest) stable Moto ROM. 2.3.5 Android and 2.6.32.9 GB kernel.

EDIT: Replaced fsimages with new one and repeated flashing. Now checking out CM9!
[Defy General] joydeep1985:
One good question . This tutorial is for CM7 and CM9 . But there are lots of other roms which are ported based on CM7 . So should we be able to put those roms into dual boot with CM9 ? since they are based on CM7 .
[Defy General] mainTAP:
Have you managed successfully run dualboot STOCK defy+ and CM9 ? What did you replace fsimages with ?

Is it working fine ? ( Can you boot back to stock as it was before installing dualboot ? )

I would like to try CM9 in dualboot as well without affecting my stock defy+.

You mentioned you've lost your motoblur data, do you think that was necessary to run CM9 in dualboot ?

Thanks
[Defy General] biozshock:
1) Yes, i managed to run ICS via this dualboot script.

2) Replaced fsimages with empty ones (from 1st post in this thread)

3) Have not tried to boot stock yet (after successful flashing). But ran it w/o problems when was trying to install it.

4) Motoblud data restores within 3 steps that usually present on first phone start

5) Yes it worth trying.

Be sure to flash Quarx ROM (one for Defy+).

ICS runs smoothly but sometimes lags a bit seems because Android is on flash card (which is much slower). Had no problem installing free apps, calling, wi-fi, e-mails. So far so good.

Since i'm just trying ICS i've created new gmail account and imported all accounts into it. This will not mess up all my apps i have on my main account.

[Defy General] crakeron:
Either flash a zip from latest/custom recovery (for CM9) or use adb whilst the 2nd rom is booted, or do it manually whilst 2nd rom is booted ;).

[Defy General] trurl3:
Why? While you on second boot install it as usual and use Titanium Backup to make it 'system app'. You have free acces to files on your Sdcard from second system. You can even reinstall aps from your TB backup of course not all, you have only approx. 300MB free place for apps...). I am using m11kkaa's multiboot with addition royale1223 Multi Boot Manager (from this thred http://xdaforums.com/showthread.php?t=1522329&highlight=multiboot+royale1223) and actually have 3 additional ROM's on my SDcard :) (MIUI, CM9qarks080312 and CM9epsy170312) and there are not any problem with switchig between them.
[Defy General] joydeep1985:

With laterst CM9 nightly 0703 there has been a problem with dual boot. The root access option vanishes from developer options . However the root access option is not a problem when CM9 is installed as the primary rom itself .:confused::confused:

Custom/Latest and Stable both use the 2nd init part - the first CM7 filesystem?

Thanks in advance!!

[Defy General] joydeep1985:
Your primary Rom i.e the 2nd init uses stable recovery and the 2nd boot it uses the latest/custom recovery . Even if you delete those image files . It wont affect your setup of 2nd init cause while you are in fsimages . You just deal with those partitions which in sdcard fsimages, not that one of nand / 2nd init rather they are of 2nd boot . So you can delete those partitions (fsimages) and can still you would continue to boot into 2nd init . However you wont b able to boot into 2nd boot anymore :)

how do i make back from dual to single boot?
[Defy General] trurl3:
What do you mean? To get rid of dualboot? Or to go back to nand ROM?

If you do not want dualboot anymore just delete /multiboot folder with installed ROM's and in bootmenu set 2nd-init as default.

If you simply want to go back to your nand ROM - reboot and in menu which opens at the end choose "reboot to NAND'. You have to do it every time you want to go back to your real ROM because multiboot_v0.5.1.zip sets up 2nd-boot as default in bootmenu.

Anyway multiboot.zip once flashed stay inside till reflashing whole ROM in real or recovering from nandroid backup.

Hey, I installed cm7.2-rc1 as main ROM and besagt cm9 by epsylon with Android 4.0.4 as VFS. I know that root is deactivated in cm9, but I don't find the option to activate it. Is it due to this release of cm9 or maybe it is because of the vfs
[Defy General] crakeron:
CM9 (and generally all custom ROMs) is pre-rooted. You do have root activated. Either you don't know it, or you don't have the superuser app to grand root permissions to other apps. Check if you have root by downloading TI Backup. If you're not rooted, the app won't work.
