[ROM][NIGHTLY] CyanogenMod 7.2-RC3+ for Huawei U8150 (June 11th)

---

Introduction
CyanogenMod is an aftermarket firmware for a number of cell phones based on the open-source Android operating system. It offers features not found in the official Android-based firmwares of vendors of these cell phones.

History (standing on the shoulders of giants)
CyanogenMod has been under development for the U8150 since early 2011. In the beginning marcnvidic started off by getting the Android device tree organized and getting initial builds working. After that tilal6991 made great progress with basic functionality, bugs, etc. I joined initially to learn about the AOSP/CyanogenMod build system, but have helped clean up the device tree, fixing a few bugs, and keeping up with the latest upstream CyanogenMod changes.

Download
Note: The CyanogenMod build server builds CM7.x releases for the U8150 once a week. I don't have time to update builds manually here anymore. Find CM builds here: http://get.cm/

Source

• Kernel: http://github.com/alanorth/kernel_huawei_u8160
• Device tree: https://github.com/CyanogenMod/andro...e_huawei_u8150
• Pending patches: http://review.cyanogenmod.com/#q,sta...awei_u8150,n,z

Known issues*

• Development tools like adb and DDMS see the device as "????????????" instead of showing the serial number (related to the Wifi MAC issue below)
• The wifi MAC address is not read from hardware, it is set statically (see here, possible fix).
• FM Radio (probably won't get fixed)
• Battery usage slightly worse than stock (terrible in some cases)
• Overclocking frequencies not as stable as stock or on U8150 kernel (due to the voltages used in the U8160 kernel sources we're using, see arch/arm/mach-msm/acpuclock-7x30.c)

Fixed issues / changes

June 11, 2012

• Update to latest CyanogenMod 7 source

Thanks

• marcnvidic - initial CM6 port, device tree, etc.
• tilal6991 - holding the candle for so many months after marcnvidic left, lots of bug fixes, device tree work, etc
• subpsyke/psyke83 - being a badass, fixing lots of stuff in his Huawei U8160 port which also helped us.
• CyanogenMod team (koush, defer, turl, et al for helping me when I'm stuck with repo, git, gerrit, etc).

Reserved for detailed ClockworkMod Recovery install instructions

Are resolved these old bug?
hidden SSid
mac address
audio distorted
3mpx photo
tethering usb e wifi

I am here too - ha ha!

@Giogts:
-USB and wifi tethering work
-3mpx photo is not solved, but it was stated in the big thread that it was "enlarged" from 2mpx to 3mpx in the original stock rom while the camera ccd chip supports only pics up to 2mpx ..so tehnically it is not a bug anymore
-mac adress is still different then the original one
-hidden ssid works when you add the network manually, othewise it's not shown on the scan
-audio was a bit crackling in the Dec 5 version but in Jan 17 version for me it's a bit better. i don't know if it's fixed for good

@aorth: excellent thread. subscribed

Subscribed, good work, i've just flashed your build on my old 8150.

As I already said HERE, our CCD cannot take real 3.2 mp photo. They were just software upscaled/tweaked on stock roms and custom rom based on a stock one (FusionIdeos, Leandroid etc..) (CyanogenMod isn't based on a stock one, it's build from sources).

Awesome job! Finaly a fresh thread! 17 jan is way better then 5 dec one in terms of battery!

One thing i would like to ask why doesnt the led blink on cm7 anymore?



sent from my U8150 using my thumb!
