CM7 vs CM9 kernel - Defy Q&A, Help & Troubleshooting

Hello,
I have old Defy with Bayer module. Which software is better for me? I heard that GB kernel has a bug - full CPU thortle. But when it happens ? Does CM9 have any other bugs ? And is it possible to record videos on this?
Thank you for answers !

Hi,
which Kernel is better is related to the software you are using. But you can't be wrong to use the CM7 Kerner with Quarx newest builds. If you want to use Cyanogenmod 9 I would also recommend you to stay on Froyo-Builds, it causes less problems with the camera.

Im of course considering proper kernel for proper CM7 version.

If you use CM7, I see no reason to change to a GB-Kernel-Version, cause it makes nothing better. In additional the newest nighties are made by Quarx for the Froyo-Kernel. See on ge. tt/8rDd1nC
Edit: No space between the dot and the t

But I've heard that GB kernel is much faster... This problem with max CPU use is problem of soft and will be never fixed on this kernel ?

kernel doubt
hi sorry to bother you
i flashed cm7.1.0-rc1.5-jordan-signed.zip a couple months ago, working fine.
i've been wanting to try out the new cm9 builds.
mi kernel version is [email protected]# 1 i dont know if this "froyo kernel" o "gingerbread kernel"
1_which rom sould i flash... quarx (29 jan) or epsylon3 ( 31 jan)?
2_do i need to flash another kernel previously?
3_what steps do i need to take to flash it?
4_will i be able to downgrade back to froyo 2.2.1 or at least my current cm7 ?
thanks a million

1) both roms use froyo kernel, so you can try anyone.
2) you don't have to flash any kernel, cm7 uses froyo kernel aswell
3) I've just flashed 31Jan, I was using cm7 previously. What i did:
-reboot, when the motorolla logo displays, wait for the blue led to show and then press volume down.
-then you go to recovery, latest recovery. (I highly recomend to do a backup (nandroid) before wiping data)
-wipe data/factory reset, wipe cache.
-install from zip file, and choose either 29jan or 31jan zipfile. (remeber 31jan has gapps included, if you go for 29jan you should install gapps too)
-wipe cache.
-go to advanced, wipe dalvik cache.
-reboot!
First time to boot will take some minutes.
4) If you want to get back to cm7, just recover your backup (nandroid) or follow the same steps in 3) but installing cm7 zipfile.
Hope it helps you, if any more experienced user finds an error in what i've said, please correct me.

[Q] Going from Argen2stone to Tezet's CM9?

I got an old version of Argent2Stone (1.7 or 1.8, I think) on my phone. Do I need to do something specific or should I try to install as if my phone is on stock froyo?
Thanks!

copy zip from tezet`s site into sd card
go to recovery in bootmenu
make full backup (system,data,cache,boot and devtree)
double wipe (wipe cache and dalvik cache)
optionally wipe battery stats
Install zip from sdcard
I'll add this to the operations described by ZyrByt :
Do a full backup with CWM before flashing !
As CM9 is still in developpement, you can have annoying issues.
The backup give you a way of quick rollback to your old AgentStone.
EDIT : HOOOPS !! Too fast readoing... ZyrByt already said what to do with the backup sorry;..

[Q]": DEFY+ BL7 Rooted .. now what for CM7.2

I have successfully rooted my DEFY+ (BL7, build 4.5.1-134_DFP-231) using this post
I got root and have the 2nd-init apk in my phone. I installed the stable for Cm version of bootloader, and tried to install CM7.2 nightly from 27th Jan (here). but after reboot, it went to a bootloop.
For now, I have reflashed the original sfbs in the first link and restored to stock.
Now, can anyone detail me the steps from installing the 2nd-init to geting the CM7.2 live on my phone please..
PS: I don't mind buying a beer or two for the help
Try flashing cm72-20120506-NIGHTLY-Defy+.zip by Quarx. Just root your phone again, install 2nd-init 2.0, chose LATEST and then flash the above build, without flashing kernels. Remember to wipe data/cache and dalvik cache before flashing CM7.2 and cache and dalvik after that.
Thanks Auris! I am already rooted now. So below are the steps I should take: ?
1. Install 2nd-init. Choose latest.
2. Reboot, it will go to 2nd-init menu.
3. Choose recovery--custom recovery
4. Wipe data, cache & dalvik cache
5. Install the Quarx Build you linked
6. Install Gapps
7. Wipe Cache & Dalvik cache
8. Reboot
9. In 2nd-init menu, choose 2nd-init boot
Is that all? Please let me know if I missed anything

Use the CM7.2 build for froyo kernel. You don't need to flash any other kernel.

Maniac's one is the most up to date and polished I think as he's the only
one that actively since works on GB.... Quarx stable is really old but still a great rom
and since you're already rooted with clockworkmod you don't need to flash a sbf..... Just full
wipe data and cache wipe then dalvik cache..... Good luck and I hope you enjoy your experience
Don't install CM7.2 if you want battery life .
I only get 8hs of battery with light use and with ms2ginger 3.0 gets 12hs of battery life with wi-fi , browsing and somes games
Try MS2ginger 3.0 + greenbread mod (ms2ginger 4.0 lags with green lens) , this rom have a gingerbread kernel (no battery drops and better battery backup) :good::good::good: or Whiterabbit 1.6 (custom cm7)

You may not even need to wipe data but It's advised or at least I do it so I have not problems with my apps. If you do wipe data remember to backup first and when restoring try not to restore data of system apps that's where most issues arise from. If you don't wipe data then cache and davlik wipe install the rom then i would cache and davlik wipe again for safe measure and reboot and enjoy. Yes you will need to reflash gapps if you data wiped. You have a green lens defy right??? You only need a kernel if you have a red lense defy. Good luck.

[Q] [noob] please a step-by-step walkthrough From 'CM7' to '2ndboot CM10'

Hello everybody, as stated i title, i need a noob-mode step by step guide to install the new superb innatural quarx's '2ndboot-CM10' in my green lense 525 with the latest CM7 nighly in it.
I know most of us are using the phone for everyday use, so most likely is using the "stable" CM7 as well.
I read that cm10 is almost good for everyday use by now, and it's time to upgrade.
Somebody could do me this favour, I promise to thank...
just reboot into recovery and wipe data and chache, if u want wipe battery stats also and it's done. simply install it like all custom roms.
0. Go to recovery
1. Make a Nandroid backup (recommended)
2. Wipe data, cache and dalvik
3. Install non-2ndboot CM10 (MB525 for Defy or MB526 for Defy+ or red lense Defy with Gingerbread kernel)
4. Reboot to stable recovery
5. Wipe data, cache and dalvik
6. Install latest 2ndboot CM10 build (one build for MB525 and MB526)
7. Install Gapps
8. Wipe cache and dalvik
9. Reboot

hi nasty and thanks for the complete answer.
I read somewhere that the 'old' non 2ndboot cm10 doesn't contains the kernel, it is true or not?
If yes do i need to flash actually only the kernel or the complete 'old' rom?
tks

Why those steps ? They are not necessary !
As already mentioned the steps above me are not necessary and for your question
The kernel is included in the Rom simply choose the latest nightly, BUT sometimes Quarx makes some Kernel Updates for a specific nightly then this is only a Kernel Update but atm there are no Kernel Updates so its not necessary

It is safer to update from a CM10 ROM.

Only 2ndboot ROMs contain custom kernel. You can install 2ndboot CM10 directly, but it is safer to install from CM10 Stable Recovery.

[Q] Motorola Defy on CM7 stucked on boot screen! Urgent!

Hi guys!
I have just rooted my Motorola Defy and installed CM7 (7.0.2) into it using the instructions provided by CM wiki. I decided to use ClockworkMod and bootmenu, since I'm on Mac OS X.
Well, everything went fine until I tried to open the Market app, which was not working. Searching the web, I found that the solution could be wiping user data and caché through the recovery mode. As I could not figure out how to start the bootmenu (which I learned later), I did it through the stock recovery mode (using power + volume down)... and since that I can't boot my phone anymore!
I have already tried wiping everything again and installing CM7, but I'm still facing this problem.
Please, anyone have any ideas? I'm almost desperate.

So after doing a factory reset from stock recovery, you say you're trying to install CM7...
Are you installing this from CWM recovery?
Did you wipe Dalvik cache?
Are you using an MB525 Defy or an MB526 Defy+, and is the CM7 zip you're flashing a Defy or a Defy+ build?
>
You've probably not wiped Dalvik it seems.
In CWM recovery, go to Advanced and under that select Wipe Dalvik Cache.
Do yhis and a normal cache wipe every time you flash a ROM update. If you flash a totally new rom like CM10, wipe data also.

Hi! Thanks for the reply, and sorry for my English.
Actually, I have already installed CM7 and it worked fine, except for the Market app. Trying to solve this, I have done a factory reset from stock recovery and, since that, CM7 is locked to the boot screen.
And yes, I have installed CM7 through CWM recovery, and I'm using a MB525 Defy.
Well, I have just tried wiping Dalvik Cache, but it seem as if nothing happens when I select this.
Ya wiping Dalvik is very fast, but it will make a lot of difference. Every time you update your ROM, wipe both cache and dalvik.
>
If this didn't solve your problem, try wiping market data and uninstalling market updates. They will reinstall on their own.
>
If even that doesn't work, reflash the GAPPS zip.
BTW, shouldn't you be on CM7.2? That's the latest CM7 as far as I know.

You can only wipe data from an app trough the Apps Manager inside CM7 (that means you have to boot up your phone).
Try flashing the newest CM7.2 and the newest GAPPS for CM7.2.
If the problem persists, return your phone to the old .sbf and start all over again.

Well, I really can't boot my phone. I just can access bootloader and both recovery modes from stock and CWM (bootmenu).
Do you know how can I flash a .sbf on OS X? I know a lot of programs for Windows, and I also have found a script (sbf_flash.sh) that should work on Mac, but it seems that a lot of people are having problems in OS X (including myself).

OK. Go to CWM recovery. Wipe data. Wipe cache. Wipe dalvik.
Now install WhiteRabbit 1.8 or Maniac's CM7.2.
Flash the GAPPS packages linked in the respective threads.
Now AGAIN wipe cache and dalvik.
You should boot normally.

Hi,
I have just reflashed a retailer version using RSD on a friend's computer and it is now back to life... now I'm figuring out what is the best path to follow.
Thanks for the help!
Factory resetting from stock recovery messes up custom Rom!! If You are on custom rom, you have to use CWM for doing wipe etc...

Yeah... I know that. I just wanted to rollback everything and have the phone back. I'm now studying which is the best ROM for me to install again, but meanwhile, I have my phone working.
