Many people want to run a working froyo on their devices.
This won't be possible in a clean way without compiling a new kernel.
To archive this goal, we need to merge the Huawei specific device drivers (which are for 2.6.29) into a new kernel tree, the 2.6.32.9 one (or even 2.6.35 but 2.6.32.9 comes first since it is stable and thus important to us).
I did some research and preliminary work which I will explain here:
- The base kernel Huawei started with is available here (gitweb) - also check their wiki.
- Huawei started with the Q8650BSDCANLYA324020 tag on the donut_glazed branch (see instructions at the end of the post)
- Huawei has written it's own board driver (note they have used a Q8650 kernel release not a MSM7x25 one, most likely because this board driver is a little older and was not available for the version they wanted)
- After they were finished writing their drivers they released the kernel source (as you can download it from Huawei)
I have checked out the Q8650BSDCANLYA324020 base kernel version and diffed it against the kernel release of Huawei, generated a patch file (and stripped out the DOS linebreaks wtf) which can be applied to the base kernel.
Applying this patch to a more recent kernel (2.6.32.9) is not possible without merging the code into the new kernel tree (and since I'm not a programmer I can't do it - this is were your help is needed).
The other question is in which kernel tree we can port the patch I have extracted. I think we can use Q8650BSDCANLYA504005 on the froyo_almond branch since Huawei used an older version of it. Merging it into the AOSP msm-2.6.32.9 tree may be possible too (but the code aurora msm kernel is an improved AOSP version, so I guess we want that one).
My patch (and some non-pulse-mini fixup patch) alongside with a freshly extracted and fixed .config for the U8120 can be found at http://nico.core.ws/misc/huawei_kernel_u8100_8110_8120/
To port the source you need to checkout the original source (Q8650BSDCANLYA324020), create a new branch in which you apply the Huawei patch, then checkout the froyo kernel (Q8650BSDCANLYA504005) and merge your branch containing the changes from the patch into it.
Another way may be porting the froyo kernel tree back to the eclair one with Huawei patches.
Please post any results/questions/etc. here!
If we should get this working we can also enable the GPU driver (Adreno 200) as requested by many people (and much more (CyanogenMOD anyone? )).
Appendix:
Instructions on how to get the original source:
$ git clone git://codeaurora.org/kernel/msm.git
$ git checkout Q8650BSDCANLYA324020
Instructions on how to apply the patch (assuming "msm" is the kernel tree):
$ cp diff_kernel_msm_aurora_Q8650BSDCANLYA324020.diff msm/
$ cd msm/
$ patch -p1 < diff_kernel_msm_aurora_Q8650BSDCANLYA324020.diff
If you are compiling for U8100 or U8120 phones, you need to apply another
patch which fixes sensors (otherwise your phone won't be able to read battery
level and stuff):
$ cp needed_fixes_for_non_u8110_devices.diff msm/
$ cd msm/
$ patch -p1 < needed_fixes_for_non_u8110_devices.diff
Note that the above instructions will get you nothing new, only the kernel already running on your device.
This thread is about porting the Huawei patch to a froyo kernel.
Very nice! Thank you for this topic!
I hope this will be successfull
Are the Atheros sources included aswell?

To be honest, I don't know. They should be in there though (maybe under a more generic driver name or integrated in the board driver) otherwise Huawei would have violated the GPL.
The problems with the fixes:
wifi
They got almost wifi working in other post
radio
FM radio too with an 3rd party app
dpad
dpad crash in this post too 2 pages back just disable this
screen calibration
calibration fix can meaby be fixed with HTC calibrate??(its an calibration app)
sound
I solve the sound problem with my phone is to replace the libaudio.so from 2.1rom,maybe you can try.\

Basically this is the complete kernel source for froyo without Huawei patches (it's the wrong tag too).
When we have ported the drivers we easily can enable that driver.

Thats the source for the U8150, not the ones we want. The only thing which may help us at a future point in there is the kernel config.

If you compile a kernel right now you'd get a kernel that won't read the batterylevel and the magnetic compass won't work so we need to make a few adjustments.

This is in needed_fixes_for_non_u8110_devices.diff
So nothing new here.
So what can we do to help?
Is there a way to chat in XDA?
Any news on this?

Possible to make an update.zip for this Adreno 200 driver on 2.1 while 2.2 is not working?

I dont think so he's not saying anything about it for 1 week now...
But even if he doesnt say anything, this topic can be useful.
Someone with git/kernel/c knowledge need to port the patch.

You need some elemental knowledge in C and then simply cut and paste the text in the files.
However, I think that it is more important to be able to compile from source and install the existing Huawei Linux kernel for the U8120. That is, can we compile from source all the code for Android 2.1-update1 and install on the U8120?
It might be good to try to get CyanogenMod on the U8120 for the kernel version that Huawei provides. Then, we can cut down the 1.5MB patch into smaller parts, and even try to get the drivers included in the Linux kernel.
I have not idea how to compile Android 2.1-update1 and get the plain old android source on the phone. I am willing to invest the CPU clocks to compile it, though.

Dunno, it's quite a huge and advanced task.

maybe we can get some kernel developers from the desire topic to help us?
I have send Benee, deovferreira, Kali- a PM maybe they could help us

Can we just replace the normal kernel in the command list for the new kernel so you apply patch in the new kernel(u8150)froyo kernel?
I have had contact with benee a kernel developer for the htc desire. He is willing to help but he needs a device so he can test kernels he build. It is not possible to build kernels without a device because this is a huge project without a good base.
Maybe we can setup a fund raiser to get him a device?
Hi guys, I've been hiding out over on slate droid for a bit - I picked up a pandigital novel for free and I've been working on getting it to run things other than eclair. I have a working honeycomb port for it - woot - butttt pandigital refuses to release kernel source code for the device. velocity micro released a cookie cutter version of the same device and won't give up the kernel source either so heres the trouble - without a new kernel module honeycomb and gingerbread have no wifi.
Is it possible to compile a generic kernel module or a signed one for this kernel with no kernel source? Help please.
Maybe the full might of xda could get pandigital to fork over the source code but seeing as how we don't have a pandigital section demand for this is low here. I'm disgusted by the way these companies have been stealing open source software.
http://www.slatedroid.com/topic/23492-honeycomb-it-doesnt-run-very-well-on-my-novel-yet/
There's a link to the issue - I'm not sure if it's polite to link to another forum here - mods remove it if you like. That entire thread would be here on xda if we had a novel device forum
See u back at SLatedroid.

Hello:
I'm trying to build a tun module for my cellphone android OS. I'm using this guide to learn what I'm doing since it is very complete and well written:
Code:
http://xda-university.com/as-a-developer/getting-started-building-a-kernel-from-source
The problems that I found are a few:
- I can't find the source code of Gingerbread for my Galaxy Fit GT-S5670L.
Here comes confusion one, is the kernel itself the source code that I'm looking for or I need the kernel's source code? I'm confuse.
My cellphone has this kernel: Linux localhost 2.6.35.7-perf-CL700532 #1 PREEMPT Wed Nov 2 01:11:19 kst 2011 armv61 GNU/Linux
So according to this:
Code:
http://forum.xda-developers.com/showthread.php?t=1808167
I've gone to all these pages looking for my kernel or kernel's source code which should be Gingerbread:
Code:
* http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=gt-s56
* https://www.codeaurora.org/cgit/quic/le/kernel/samsung/
* https://android.googlesource.com/kernel/samsung/
I can't find the source code or kernel's source code for my Samsung Galaxy Fit GT-S5670L because I don't even know what I'm looking for exactly. Should I look for Gingerbread's kernel, or Galaxy Fit GT-S5670L Gingerbread's kernel?
At Samsung code source there isn't even my model of cellphone. (Thank you Samsung, because my phone is old doesn't mean that I will not need support)
Nevertheless I've downloaded the kernel/samsung from Android Google source with git command.
- Confusion two, nothing downloaded, I mean, the folder was created but it was empty.
.Where the 400 MB, more or less, went?!
I'm running Debian on my desktop computer.
- Confusion number three, I got the ADK and NDK tools, have no idea how to install them but I'll search and figure this out.
- Confusion four: the ADB, could someone point me to a good tutorial how to work with this.
- Confusion five: I know because I've bricked my phone several (SEVERAL) times that is not the same: Fit GT-S5670 than Fit GT-S5670L so I can't download or test or work with a kernel that it's not meant to be for my cellphone, that is if there is a kernel or kernel's source code for each model or variant of the Fit cellphones.
Please oh please help me!!
I have been trying to work with this for the last 3 weeks and surf the net for hours and I don't know what to do anymore. I have even contemplate the idea of buy a second-hand phone, though I really like mine.
PS. Sorry for my bad english.
Hope, reeeeeeally hope you guys can help me.
Hi,
There are many guides and tutorials here, and you can ask for help if you're still stuck,

Good luck!
Hello Folks,
I am searching Testers for DIOS 12.1 My new upcoming Xperia exclusive OS.
Things that don't work actually on Sagami Boards due to the Xperia Software Binaries:
-Mobile Data
-Wifi
-NFC
-Battery Status (No Infos)
Make sure You know what You do. Flash the OEM Software binaries to use this AOSP/SODP based ROM. Flash all Images included in My ZIPs. OTAs can be applied over ADB and Recovery after You have flashed My Kernels/Recoveries. Feel free to ask Me out if You have Questions and consider Joining Me on Social Media or Discord to stay up-to-date.

Hi OP, since you are the original developer for this ROM, I changed the tag from General to Development.
Also, because you are posting this ROM yourself, could you please also post a link to kernel source repo? As on XDA we need to comply with GPL v2 which requires kernel source to be open source.
Thank you very much.

Thanks for the Help! Since i am using the SODP Device Trees are we going with Pre-Compiled Kernels from the SODP for now.
