Good job!

Hi guys, havent been on the forums for long time, but I was checking stuff here for a last of few days, and I must say, good job guys!
Especially you rootdefyxt320, good job! Keep up.
I traded the Defy Mini with my mom for a iPhone 3GS, it was a bad decision. This phone is real crap.
I am maybe getting a Huawei Ascen Y300, what do you think about it, anybody tried it?

Thanks junk031.
My friend had it and I was a decent phone. You will have a good experience with it. Is your mum going to return your Defy Mini back?

If I buy the Huawei, no.
But if I dont buy it, then my mother will give the Defy Mini back
It is still rooted with Link2SD and stuff, so its good if I get it back :D
Im hoping to get the Huawei because of the bigger screen and better performance, but Defy Mini is still a nice phone.

Good luck with your school work bro!
For the moment i have my phone overclocked to 710 MHZ, stable, with smartassV2, the performance is very good, i'm playing FIFA 12, with few lags :victory: 26 to 30 fps, with a little help of chainfire.
I'm trying to play FIFA 14, but after the messi screen, i have black screen with music background, there's a trouble with the graphics, i think. Only one time i saw the menu screen, but i closed and opened it again and it give me the black screen like before xD
I attached my build.prop if anyone know better tweaks or how get better performance :eek:.

Have excellent exams and come back as soon as u can. We count with you to find out hijack on defy mini to 2nd boot into CM / custom kernel or another way to do it. Several people in my country ask me about it. You will be famous if you solve it.

    First custom kernel for Defy Mini XT320/XT321 is here!

    Featured on XDA Portal: http://www.xda-developers.com/android/first-custom-kernel-for-the-motorola-defy-mini-mini-xt320xt32/

    @MauroSZ @Bernd.Defy @junk031

    Despite us having a locked bootloader, we can boot a custom kernel via fastboot.

    Technical Details:

    Fastboot is stored as a secondary bootloader in Defy Mini. On older firmwares, the secondary bootloader had fastboot enabled but newer firmwares don't. This is why Motorola left a vulnerability in fastboot which allowed us to fastboot boot img files.

    Kernel Source: https://github.com/rootdefyxt320/android_kernel_motorola_tinboost

    This kernel is made for Defy Mini stock ROM's.

    Details:
    Linux Kernel version 2.6.38.6

    Features:
    -Swap
    -Insecure

    To Do:
    -Add overclock
    -Add custom governors

    Limitations:
    -You must use fastboot everytime you want to boot a custom kernel so it requires a computer.

    Instructions:

    1. Download boot.img from attachments
    2. Download modules.zip from attachments.
    3. Make sure you have CWM Recovery, if not download it from Post #41
    4. Now boot into CWM Recovery using the batch script or typing the command in cmd
    Code: 
    fastboot boot name-of-recovery.img
    4. Now type these commands in cmd:

    Code: 
    adb shell mount -a
    Code: 
    adb push modules.zip /sdcard
    Code: 
    adb shell
    Code: 
    cd /system/lib/modules
    Code: 
    busybox unzip /sdcard/modules.zip

    Then it will ask you to overwrite the files, press A on the keyboard.

    Now type the next commands in cmd:

    Code: 
    cd /system/lib
    Code: 
    chmod 755 modules/*
    Code: 
    exit
    Code: 
    adb reboot-bootloader
    Code: 
    fastboot boot boot.img

    Updated to v2 in Post 8: http://xdaforums.com/showpost.php?p=51104120&postcount=8

    Same installation instructions as v1.

    Hey, I managed to improve the performance of the kernel also by using LZMA compression instead of GZIP, switching to SLUB allocator and deadline I/O scheduler and overclock also.

    Kernel v2 Update:

    -Uses LZMA compression
    -Enabled OTG Support
    -Switched to SLUB Allocator
    -Added Deadline I/O Scheduler
    -Default VDD=7 for better overclocking with Bernd.Defy's overclock module.
    -Enable zRAM.

    You must install the new modules otherwise device will bootloop!

    I'm busy studying for exams these days. Kexec requires a lot of hard work before we can even boot the kexec custom kernel. Remember, I'm just a 16 year old dev, so got to have priorities in school work first ;)
