[Q] [HELP] Downgrading to froyo kernel WIUI - Defy Q&A, Help & Troubleshooting

I've really searched everywhere but it's too complicated and i can't seem to find a solution.
So, my issue is that i have installed the ICS CM9 with GB kernel, but i want to install the WIUI 2.4.20 Stable (GB) version that is based on MiuiAndroid 2.3.7 (GB).
I am assuming it requires the Froyo kernel, and if so, i need to somehow downgrade it to froyo before installing it, but i don't know hot to do it...
can anyone please help me?

Also the kernel version of my rom is "2.6.32.9-g21f1a48"

Questions go in the Q&A section

as far as i remember 32 is froyos kernel..(35 is gb's kernel)
so what is the problem???

Numbers are the same I thought. If you flashedthe gingerbread kernel from the recovery, just search for the froyo kernel zip (there is one on epsy's site) and flash it with the froyo based ROM.
Don't forget to wipe.

[Q] Defy Plus MIUI

I am currently trying to get full battery of my defy+ to work under MIUI. Being CM based i assumed it would work with the CM battery patch. It doesn't however. I know which files need to be replaced, would it be a good idea to just grab the files from the CM9 defy+ build and replace them?
For those that are interested doesn't work = battery only showing full with question mark icon.
Having same problem and seems there is total silence in all forums concerning this issue. If you manage to solve it please let me know !
Hey, guys I'm using MIUI Pikachu Edition by einsteinno1 and it has full DEFY+ support (battery charges up to 100%)
It's overall an awesome ROM, after trying CM7.2, latest WIUI and MS2G v3, Pikachu is the best one for me.
My DEFY+ was on 2.3.5, so I flashed it down to Froyo before flashing Pikachu
Cheers!
I have the same Defy 2.3.5 but I don't know how to install a diffrent ROM/interface ...

Search this wonderful Forum - There are many threads telling you how to install a new ROM / interface
Well then I will definitely give Miui Pikachu edition a try As far as I understand Froyo version is the best to use to flash Miui right ?
Hi all,
About the Defy+ battery. This battery is only support by GB kernel. So nevermind the patch you applied, you'll always have a bad result. This patch works on CM 7.2 Defy + because this rom doesn't incluse the kernel and use the GB one of your phone.
So the only solution is what nisky+ said... Flash before the 2.3.6 SBF on the dev forum who allow you to flash a Froyo kernel first...

Froyo is the safest way, yes, and it will work without problems. It should work when flashed over 2.3.4, too, but I haven't tried that, myself.
@mdt24 Then how come I don't have battery problems now when Froyo's kernel is used
P.S. It's niksy, not nisky
Hi niksy ;-)
It's because I think this rom doesn't incluse kernel, so you always run a 2.3.4 GB Kernel...
quote from Miui Pikachu edition : IMPORANT!!! this Rom works only on Defy or Defy+ with Froyo Kernel or Gingerbread 2.3.4/5 Kernel. All with 2.3.6 Kernel have to downgrade to Froyo Kernel, because the new Motorola Kernel won't work with MIUI. Just use this Tutorial on XDA Developers
But I could be wrong in my deduction, so Please, can you give us the number of the kernel you have with this pikachu rom ?...
What I did before was downgrade from 2.3.6 using the sbf the dev provided that allows you to downgrade to froyo then I flashed Miui official rom and still had problems with battery. Kernel version currently is : 2.6.32.9gb08c3c8 if that makes any sense to you cause I personally just don't know anything bout kernels... I just downloaded pikachu Miui and will give a try soon and share the results with you
Hey all, thanks for the replies. I already know about the limitations of the patch and which versions the driver works with. That is why i flashed the 2.3.4 kernel before using MIUI and therefore the defy + patch. I just don't get why it doesn't work, do i need to use a defy+ kernel?
I will grab the files used in the working MIUI Defy+ rom and package them as a flashable .zip for other users.

Mate, you are right about the ROM, it doesn't include any kernel, but I said that I flashed that special version 6 Froyo (that's a full sbf) before flashing Pikachu!

The kernel you mentionned is a froyo kernel...
As you all I try to understand why it's possible that the defy+'s battery works or not with the patch. It's sure it works with a 2.3.6 GB kernel and a patch for the system (battd, lib) used by the rom if the new rom doesn't include a kernel.
It seems that if the rom include a froyo kernel the patch doesn't work...
So... may be a way to understand

Yes but I'm pretty sure than this special version has a GB kernel. It's just the bootloader who accept all kind of kernel...
Check your Kernel number, I think you must have something like this 2.6.32.9-gbdd614e...
Ok after some testing I can tell you that the battery charged to 100% only the first time I booted.Since then it has only charged till 90%. I also did calibrate the battery the first time I flashed the Rom but no results

It's 2.6.32.9-gb08c3c8 - the one you said it's Froyo Just checked!
And for the battery... First time it charged to 100%, this time it stuck at 90%. Quite weird... But, that is with Froyo kernel, as we've come to conclude.
But, on the other hand, my bro's got a DEFY+, too, with CM7.2 on it and with Gingerbread kernel (27th January DEFY+ nightly) and the battery goes to 100% every time. I will test Pikachu on a Gingerbread kernel, cause I can't really live with this bug :-/ Will let you know how it went, now I'm off to find a 2.3.4 sbf!
I had the same idea and have already downloaded a full 2.3.4 GB sbf to check just that !
i wish a 2.3.4 GB kernel can fix that, although I think the only kernel able to fix this is 2.3.5 and above
Hi.. I m new to android... I just want to ask how can I add music contol to notification toogle bar like that in cm mod..... I m using pikachu edition on my defy plus and its really great ... I haven't faced any problem till now.. thank u dev for such a beautiful rom...

[Q] [q] cm9/ics/gapps - defy+ 2.3.6 kernal

[Q] hello sir,
Do own Defy+2.3.6 (ryt now using MS2Ginger 3 by walter79 ), want to use CM9/ICS, downloaded zip CM9-NIGHTLY-120112-Defy+.zip & CM9 kernel. kindly suggest proper installation procedure and info abt the ics gapps versions which one to use. i dont want to use other kernal rather than 2.3.6 can i flash CM9 on stock rom
waiting for ur humble replies ☻thanks in advance☻
God bless you All.
Why don't you want to use the Froyo kernel? I wouldn't use this nightly. You can't even phone with it! If you have BL6, flash the BL6-SBF with Froyo-kernel.
Don't use the flashlight until you flashed the CM7-kernel, you could burn it with the Chinese kernel of this SBF.
Then root the phone with the latest SuperOneClick and (after backup) follow my instructions here. Use the latest CM9-zip, ICS-Google-apps and the CM7-kernel(NOT the CM9-kernel) instead of the zips in that post. If you want to have the Motorola-Bootlogo back, also flash the attached Red_M_Logo.zip, or use my CM9-Bootlogo.zip. Flash the CM9-Music.zip if you want to use the new CM9 music app (it's very good, i can recommend it).
If you have BL7, i would wait until eppy makes a build for the Defy+ kernel.
thanks for your replies,
please let me know checking battery version ( bl5,bl6,bl7 ),my defy mfg. date is dec 2011 , details on battery HF5X, b052r984-1001, model L-L-L- DC111109.
and CM9 GB kernel is available so why not to use it, hope u clear my mind.

defy + wont be able to get update of 4.0 do not even try for this
I have a Defy+ with CM9/ICS, it works!
i think i try flashing it on my stock rom... i think eppsy build for gb builds hope no downgrading is required i guess any suggestions and recommendations are welcome.
WHAT VERSION HAVE YOU FLASHED ?
I mean which build are you using with Defy+ ?
i am using stock 2.3.6 and i tried
stock/cm 7.2 nightly.
stock/ics latest builds
works well but no network on second booted rom doesnt get any network ( no EMIE )
hope some one fix this soon or some one did let me know

Did you try using basebandswitcher? Just to search for a frequency similar to your stock baseband? I think you did because default ms2ginger baseband definitely isn't what you seem to be running on stock 2.3.6...
Oh, and btdubs I think Mister Ypsilon is right about using froyo kernel builds for CM9. Your nightly doesn't seem to be too stable.
*EDIT
Oh and veeranna don't forget, BL version (BL5/6/7) is not your battery version. It's the version of the bootloader, and it is very important when it comes to downgradeability.
search it up, I don't do a very good job of explaining bootloader stuff.
Its awesome but lil buggy
I did it! Installed Froyo SBF, rooted, 2nd init, then CM9 for Defy, CM7 kernel, slept at 5A.M :O and bingo there was a pretty stable ICS but without camera! After playing around with it for few hours.. Tested NFS Shift, Angry Birds and everything was smooth as butter except that there was no Camera due to which I restored it back using a full SBF flash and my Nandroid backup
Can be used if you don't need a camera..!
I have a Defy+ flashed with stock 2.3.6 SBF en.asia
http://forum.xda-developers.com/showpost.php?p=20097916&postcount=3
Check this it is working fine. Tested on my moto after a full fresh Defy+ 2.3.6 SBF flash.
There are more stable roms built by quarx and epsylon3 in the defy development thread. Camera works and camcorder works for some users. These devs are geniuses.

Unable to use ICS 4.0.3

HI all,
Am using Defy MB525
Yesterday I tried to install ICS 4.0.3 Mar 17 build for defy+,I did factory reset and installed from SD card (ICS build,Gapps,Batteryfix),I didn’t flash any kernals like one of our forum member told, But my defy is stucked on boot logo.I tried many times but doesn’t work So again am back to 2.3.7 Version. My kernel version 2.6.32.9-gb08c3c8
Why this happened to me?
What is the procedure?
If you dont know what you are doing dont install.ics is still beta its a nightly ..and is improving day by day moreover hwa 2D is still missing without it..cm9 is just a theme like Gb..i would say better stick to stock..or flash quarx defy+ cm7 nnightly..

Sorry, I've only flashed CM9 on my defy+ and I have kernel 2.6.32.9-gbdd614e etc. I't's not exactly the same, so maybe I'm wrong about not flashing the CM9 kernel! I actualy think you have froyo kernel!
EDIT: Yes, you have FROYO kernel! Go ahead and flash the CM9 kernel! Sorry
you must flash the SBF of 2.3

If you don't know what you are talking about, then just DON'T! If he flashes stock sbf 2.3, he will never be able to go back to Froyo. All he needs to do is flash the CM9 GB kernel.
As Auris told never flash 2.3 SBF until you DONT want to downgrade! What you said you did is absolutely fine. Just flash CM9GB kernel and it will work. But anyways I don't understand why would you want to flash the CM9 Defy+ ROm because Defy ROM is likely to be updated sooner and CM officialy support Defy!
My fault! In an other thread he didn't specify all those numbers after 2.6.32.9-gbdd so I thought he had gingerbread kernel and told him to flash the plus builds!

[Q] how to install GB kernel on froyo CM9

hello guys, thanks for all the patience with me haha, but i dont understand it anymore.. im currently running CM9 from epps on my red lens defy with froyo kernel.
Since its a little bit to buggy for me i want to change to a different CM9 but also want the GB kernel.
What to do? just download the CM9 GB build and install it just the same way as i did with CM9 froyo kernel?
I found a thread on this forum that seems really complicated and a little bit to mutch work but i want to do it the right way and not mess up my phone.

so i just download GB build CM9, put the zip on my sd card, install it and then its done?
U should also download cm9 kernel.zip from the auris's thread in defy general thread, flash it also..
Sent from my MB526 using Tapatalk 2
yeaaay it worked, pretty awesome. also it didnt delete anything from my phone which comes in pretty handy when updating the rom. so i dont have to backup everything again. camera is working fine also!
I'm in the same situation. What I want is to install the GB kernel, and yet remain on my CM9, and still be able to flash my original stock froyo SBF if need be, and was wondering if it would just be enough to flash the GB kernel found in Epsylon3's site, and if so, which one (since there are two there)? Secondly, would that GB kernel enable all 4 CPU frequencies?
I'm still on my original stock SBF, which is JORLA_U3_3.4.2_108-2, and has CG31.smg version = 4
Third, would I be able to flash Defy+ ROMs, such as the CM10 roms developed by Quarx, which, as far as I understand, have a custom kernel, and yet still be able to flash back to my original stock froyo SBF?

[Q] Confirming the need to downgrade before Aurora -> CM7.2?

I was just reading the guide on installing CM7.2, as my current rom (Aurora ICS), although good, is pretty unstable and buggy on my handset.
I noticed the guide specifically mentions I need to downgrade to official Froyo before trying to install CM7.2.
I have obviously already got CWM on there, so I just want to clarify if I still need to downgrade to an official Froyo rom, or can I just install CM7.2 over the top of my Aurora ICS?
Thanks.

If you are on Aurora, you MUST downgrade to Froyo before flashing CM7.2
