Dowgrading GB to previous kernels - Defy Q&A, Help & Troubleshooting

Hi guys,
I accidentally installed GB kernel (2.6.32.9-ge281b6e) on my DEFY (not defy+), when I wanted to try the new CM9...
I really liked ICS but I don't like the fact that the camera is unusable and the battery is leaking really fast. (maybe because of the kernel)
Is there any way I can downgrade the GB Kernel?
Thanks.
Nikola

did u just flashed the small CM9 kernel?

I had cm7 and wanted to instal the cm9.
I went to a thread and downloaded the GB kernel installer (cm9) and installed it from recovery, than the CM9, rebooted and... no return?

Mhhh sounds good. Try to flash the cm9 file again?

Did you wipe cache and dalvik cache before and after the flash? If you haven't, this is the most probable reason for the bootloop. Wipe them now and reboot - you should be fine now. And yes, you can always downgrade kernel, as long as you don't flash a full sbf with higher CG39.smg version.

Sry guys i havent made myself clear enough ... The phone is working fine... But no camera and battery is leaking really fast. Im not stuck in the boot phase aka bootloop... The phone has GB kernel..how to downgrade the kernel?

Just flash CM7 kernel and then a CM7 ROM. Done.

WajkIUI help

Hello. Can i install wajku normal or ICS version on my cm7 without multiboot? If i install ICS version will i lose my warranty?
I dont understand your question installing cm7 you actually losed your warranty, you can back flashing a full sbf
Motorola Defy CM7 RC 1.5 OC 1GHz
I know i can get my warranty back... but can i get it back by RSD Lite when i install WajkIUI ICS or Stable?
Yes, you cant downgrade only flashing a full sbf with a higher cg ver, flashing via cwm you can back
Motorola Defy CM7 RC 1.5 OC 1GHz
So one more time ( I dont know english so good ) If i install WajkIUI 2.1.6 i can go back with RSD? And can i install this ROM via 2ndinit without flashing back to froyo?
And What if i install 1.12.16 WajkIUI ICS rom?
Yes, just wipe data and cache in stable recovery and flash WajkUI, i didnt tried ICS version,but i think is the same if the ics zip include the gb kernel, do a backup before flashing wiui, then you can back to cm7
Motorola Defy CM7 RC 1.5 OC 1GHz
Ok thx for answer. What should i use for backup?
If you want to back to cm7 after installing wiui or if something goes wrong you can flash again cm7 after wiping data and cache and dalvik and then restore via cwm the backup and you will have the cm7 exactly it was before flashing wiui!
Motorola Defy CM7 RC 1.5 OC 1GHz
Ok I Backup by cyan recovery Thx for help!

[Q] Defy+ doesn't boot CM7 nightly roms

Hello,
I have installed CM7 for Defy(not plus) in my cellphone perfectly.
So then, I found the CM7 Defy+ nightlys and I'm trying to install it. But when I install the ROM on it and reboot, it stays in the initial logo forever.
Could you help me?
Best regards.
please help
Try another rom, like MUIU or any other rom and see if the start loop is overcome.
Did you wipe the memory after?
If you want to instal defy+ nighties, you first have to flash the gingerbread kernel. (CM9kernel.zip)
So now flash the stock ROM and start again. You probably downgraded to instal three normal defy nightly do you have to flash a defy+ ROM with the same bl nr. After that root instal 2nt... and flash the defy+ nightly (and wipe). If you want to be able to switch, you will have to flash the downgrade sbf again and flash the CM9 kernel. Then you can switch with just flashing the kernel and ROM (sbf wipe)

Do cm7 nightly have these fixes? I'm running nightly now and camera seems ok, but I don't know yet about the battery.

[Q] Cm7/9 with froyo kernel

Hey all
Was wondering who/how was a froyo kernel built or modded to boot cm7/9?
I want to attempt with other devices with froyo sources.

Nobody has moded them - they are both stock Motorola kernels - just named this way, so people know which one should they flash.
Defy can't and doesn't use custom kernels because of its locked bootloader.

does it mean the cm7 kernel is same as the stock froyo kernel which you get in defy ? Because i am having problem restoring nandroid backup of my stock froyo from cm9 . It always stuck at boot logo after restore. i have also tried advanced restore but same propblem.

Yes, it does. Have you wiped data/cache before restoring...? Did you also restore devtree and recovery images or only system and data?
P. S. And by the way it is Quarx, not QuarKX

Yeah i wiped everything and restored everything but it didn't work . But it worked when i used the normal boot option rather then 2nd-init. Why did this happen as i havn't seen the normal boot option in new recoveries.
Also thanks for the typo..

[Q] How to go back to MIUI Pickachu Edition 2.xz from CM10 nightly (18-Nov)

Hi folks!
As the title suggests, I want out from JellyBean and back to MIUI Pickachu Edition 2.xz
I think the latest 2nd boot builds have the GB kernel since I see 4 Vsel levels, so should I flash the froyo kernel?
If so, what should be the order of flashing ROM -> Kernel or other way round?
Also, I have a nandroid backup of when I had MIUI. What steps do I have to follow to restore it, i.e, do I have to flash the ROM (and/or kernel since I was on froyo kernel when the backup was taken) to restore nandroid?
I read a lot about the fuss of latest nightlies changing /system and /data to ext4, but in my case they are ext3, so I guess I should be alright?
Reason for going back is LAG! the immense amount of time to open stuff. I tried loving it, but its just too slow to the point I feel like its running Windows 8 on Intel 8086.
Please post all questions in Q&A. Thread moved there.
Hi!
My friend was in same situation and he went ahead and tried to flash MIUI Pickachu edition, but his process got stuck and now his Defy won't boot.
Hes now flashing stock Froyo sbf.
Thats the reason why I need to know instructions to get back to MIUI without going through sbf flashing.
Any help gladly appreciated!

how do I install miui and cyanogenmod both on defy MB525
any help in installing miui on defy would be much appreciated.
You need to flash a Froyo SBF. For some reasons going back to 2.3 always ends in a cache error, flashing 2.6 kernel, nandroid, fullwhipe etc. doesnt work

R U on Froyo or GB? if Froyo try to flash fixed sbf I will attached if needed.
Just flashing froyo kernel was ok for the 2nd boot builds upto 9 nov builds.
From 9th nov builds the cm10 rom formats our defy to ext4 file system, so in order to downgrade we need to flash the sbf.

My friend, thats what I have said, in my OP,
I have checked using mount command from rooted shell and I can confirm that my /data and /system are STILL in ext3 even though some say that the latest nightlies change the fs while formatting.
Try restoring your backup, you may succeed, otherwise you need to start all over again, with the sbf. I find it better to start all over anyway, no matter, what rom we are talking about. Those installed over a freshly flashed sbf proved to be snappier and absolutely bugfree - at least for me.
Simply try to restore your backup. I tried many roms so far, aslo the newest by Quarx and Epsylon and i always worked for me to install a new rom/zip/ withour anything further. Never installed a sbf.
Was quite late in posting a reply but I did end up flashing Stock Defy 2.2.2 SEA sbf.
I did flash successfully MIUI (Pikachu edition) but it was a bit off, so took a backup and flashed sbf.
Have been on stock ever since (been kinda busy).

[Q] Flashing over CM Rom but with Trinity Kernel

Hey guys.
For 4.2.X JB, Cyanogenmod has 10.1 Nightly builds...
So they will release per week or earlier...
So If I flash Rom Cyanogenmod 10.1 NOW, then Kernel Trinity Seven
If they release a new Nightly build, i pretty much have to Flash the ROM then Trinity Seven again, Over and Over until a Stable Build is built?
If that so, then im just gonna wait for a final build

yes, you have to reflash the kernel after each rom(and gapps) flash. why wait? it takes seconds to flash the kernel afterward? you dont have to flash each nightly if you dont want, but there is some kind of fix or change for each cm nightly.

why so much work? make a nandroid weekly, or every two weeks, same with titanium. my crackflashing habit never included so much work. i nandroided once a month, same with titanium. also, i always kept the last good rom in storage. i flashed rom, gapps, kernel. if things went bad, id just reflash the previous rom/gapps/kernel without wiping instead of restoring backups. much faster that way.

What? Stop doing all that.
Thats a complete waste of time.
Keep one single basic backup. Dont back up anything else.
Flash the new nightly over the old one. Nothing is lost. Even if an app was lost it will automatically be reloaded by the play store. I can factory reset and be exactly where I was automatically in 10 min.
Flash the rom flash the kernel. Done!
