Hi All.
It's my thread - port Android on Wave S8500(also S8530).
Wellcome developers and designers.
Last state of project:
06/13/2011 Now working on Android 2.3.3 (Source GB for GT-I9000 and M130K)
not working - modem and GPS.
04/04/2011 Memory allocation now is correct!
05/11/2011 I have full schematic for phone
and we're ready to get a fully working kernel.
Full decriptions of GPIO is attached.
source for kernel and initramfs here:
github.com/Oleg-k/S8500_Kernel_2.6.32
github.com/Oleg-k/initramfs_2.6.32_S8500
(real shame if you ask me)

Please expect not too much from me.
1.
My other handsets are from 2006... NEVER hold Android handset in my own Hand...
2.
I'm Windows User.
Linux/Unix ... I know only 1 or 2 Commands
I've never formated my SD Card nor any Harddrive with Linux ext4, JFS, ReiserFS or XFS
3.
I NEVER worked with IDA or something similar.
Installed yes, but then my Head exploded
Brain too small.
4.
Many missing parts...
Why I should kill my alive handset, as I have no real chance to reanimate it...
- no Riff Box
- no PCB to play with
I AM NOT the right man to port Android nor to find Security hole
You can make this post sticky.
NO joke, expect not too much from me. We can learn together... but this takes time.
Many time. Months, maybe years...
Best Regards
after many many variant, i found the right boot+sbl+param.lsf for kernel message output.
this is my last bootlogo.
how it can be seen, there is a problem with memory allocation.

Great of you to keep us posted! \o/
hmmm... as a matter of interest - I noticed you're using kernel 2.6.35.7, when I look at the original I9000 source that's 2.6.29....
what does that source say as to why it failed in bootmem.c @ line 341?
Not enough memory, permissions, wrong offset?

You mean to tell me that Meteor bundled a 512Mb memory card?
I have 4Gb on mine...this memory thing is a bit mystifying dontcha think, despite the discussion on another thread about the nand chipset.... on the one hand some say its 256Mb, others say 512Mb...
I tried the versions 2.6.32 and 2.6.35.
I post sbl+boot+param.lfs and config file for kernel making.
Last time u had problem with lcd_rst pin..did u figure that out?

No i mean Meteor gave me some (seeminly non existant) version of the wave that has 512 internal storage. Im pretty sure its meant to have 2-4gb at the minimum.

Wave S8500 have 2Gb of internal storage which are partitioned (bada 1.0.2):
-about 512Mb for messages (mail+sms);
-about 420Mb for user files;
-about 1Gb for system files (os+apps+widget+java)

How to bypass to write/overwrite Boot without JTAG?
I stuck in problems with Multiloader to write decrypted unmodified Original Boot. See here:

2.
How to build valid Bootimage for JTAG or file(s) to use your uploaded files.
Maybe you could please upload your working Bootimage from S8500?
So we had something to start with...
3.
You have working fallback/recovery plan? To get back to working bada S8500.
Or only JTAG...
4.
Anyway. Thanx for uploading files for study.
Best Regards
To adfree,
1)now the steps bada->android or android->bada is only via JTAG.
i'm don't know any other way.
2)i posted full working bootloader files in first message of my thread.
3)i will post full jtag image with semi-working android in 2 hours.

Thank you oleg_k
Last Question for today.
So I should use simple Flashtool from I9000 to flash these Boot Files into S8500 ?
Sorry for stupid Question. But I'm totally Android Noob.
Thank you for uploading files.

We can think about running SBL or any other bootloader (anybody with sources for that?) through the FOTA hole as I described in the thread:
http://forum.xda-developers.com/showthread.php?t=1020444
This way we don't need JTAG for initial flashing. It'd be also good to perform testing without touching BADA in the NAND, but we either need to reorganize partitions or boot from SD card
Best Regards,
mijoma
I think an combination will lead to success... so work together.
At this status it is maybe tooo risky to play without JTAG.
As we not know, how Android will handle Memory...
Okay, correction. I don't know.
In worst case scenario you need JTAG to reanimate Wave...
We have 2 steps/parts.
Android part.
Display, Kernel, Memory, etc...
This part is mandatory in my opinion.
Then second part, how to start Android. Then there are several theories...
BootLoader, No BootLoader, FOTA... inject via JTAG into RAM...
internal Memory or Dual Boot from SD Card...
Anyway, without proper modified Android part we can't use all our Security Holes.
As more infos we have, better, as more working solution we have.
So more chance to improve something.
At the moment we can only improve Video Quality.
Best Regards
Mijoma,
I totally agree with you,maybe this is the way to deploying android on S8500.
But now,i think about build working kernel for our s8500.
Maybe you helping with analize memory init on original bootloader?
like this - http://code.google.com/p/jetdroid/wiki/OriginalDramInit
Regards
Seems like using mijoma's discovery you should be able to replace booting and maybe make it to boot from SD card using a open source booter a compatible android kernel with selfmade drivers.
Maybe that could be the way, sadly we'd lose internal storage since we wouldn't be touching bada partition, anyway Android should be working fine from a SD card, It does properly on other handsets which internal storage is nothing more than a microSD card instead of flash memory.
I think losing 2GB on internal and XMB on microSD is a good deal for having android on our handsets. Happily I got 16GB SD on my wave xP. Anyway once you achieved that we could gather to use the internal flash memory partition
Jioma I suggest you to work with adfree (along your knowledge) and oleg_k they're our wave masters, baybe you together could gather to achieve this great project. I require you to work on this oh please jioma=(
Ok thats great news! Finally we have a method of booting other platforms on the Wave. What we need is as much information on the s5800 chipset as we can get so we know exactly what to compile and what drivers are needed in the linux kernel for android. Someone get in touch with Cyanogen mod and ask him for help and offer him a wave or something ha.
Hello,
First of all, if I seem to be rude or impolite, it's just because of my bad english, I apologize in advance...
I have bought a nook tablet 8G, cyanogenmod (android 4.3.1), as it uses to bootloop very often (and as it needs a simple wipe of data but a re-installation of the apk) every 4 or 5 boots, I thought it would be a great idea to re install a new cyanogen...I thought it would be as easy as on my samsung galaxy
But now, the only thing that it does is to reboot on recovery mode...When I try to power it on, it starts just like if it is ok, then it boots on TWRP mode (my CWM on galaxy seems to be more friendly). I have tried again to reinstall my rom, but it is said that it is "unable to mount data1".
I have also done a wipe dalvik cache but I prefer to stop and ask for further information before I do serious damages
I have also tried to install "flashable fix bootloop" but no way
Thank you very much !
Have you tried re-installing using SD-based CWM (e.g., see http://forum.xda-developers.com/showpost.php?p=51377882&postcount=163 or http://forum.xda-developers.com/showpost.php?p=50828000&postcount=1)?
Hello Digixmax,
Thank you very much for your answer.
Before asking, I have searched and I saw this post http://forum.xda-developers.com/showthread.php?t=2692403, and I am very happy to have the opportunity to be helped by the one who posted it !
I haven't tried it because there are some parts that I don't understand very well but now I'm gonna try :fingers-crossed:
- I have a 32g sd card that I would like to use for my apk, shall I use it to install CM11 or shall I buy a new one ? Will a 2G sd card be sufficient ?
- What does "set the partition ID type for the partition to 0x0C FAT32 LBA and set its Active flag" mean ? To set = let it free ? "Set its Active flag", I have no idea of what it means, will I understand by doing the manipulation ?
- For the second part, I have to download next u-boot.bin and flashing_boot.img in boot.zip from https://www.mediafire.com/folder/xjwc1a482a6ll/Nook_Tablet but I don't know wich one to choose.
What does MLO means ?
For the other points, I think it will be ok.
Oh...Is it necessary to intall CM10 before upgrading to CM11 ?
Thank you very much Digixmax, I am sorry to bother you with such stupid questions

Since your NT is already on CM, you might want to try first the method to update from an older CM version to CM11 outlined at http://forum.xda-developers.com/showthread.php?t=2670589.

Thank you very very very very very much :highfive:
Hi, So I've got a notebook that I don't use anymore and I would like to put Remix OS / Phoenix OS on it, but wherever I look I can't find any tutorial about how to get this OS on the internal HDD !
The point is that I don't want to us it on a USB drive, and I don't want a Dual Boot either, I just want to have Remix OS / Phoenix OS as the main and only operating system on that computer.
Anyone has a solution ? Already tried to take the HDD out and use USBMaker to burn the OS directly to the HDD, but USBMaker (and other software such as Unetbootin) won't even show my hdd in the USB list ...
Make usb
Yhan maje a partition on hhd than copy all files fro musb to yout partion. And than boot from partion. And i guess you di t oook either cuz there is plwnty of thread to install in on HDD
Sent from my SM-N920T using Tapatalk
Just copying the files from the USB Drive to the HDD doesn't work, I get a boot error when I try to boot from the HDD by doing so...
So I've tried everything I could, but I still can't get those OS to boot from the internal HDD ...
What error do you get... im guessing you dont have ufi system?. Try searching on youtube.. There is plenty of atep by step videos.
Sent from my SM-N920T using Tapatalk
"Boot Error" That's what appears on my screen.
Every videos are showing how to dual boot... My goal is to install this OS on my laptop which has no OS installed yet, the only thing I managed to do is to boot on Phoenix OS with the USB Key, but that's too laggy as my USB ports suck.
Yes I'm on Legacy.
The strange part is that they don't provide a bootable image which actually INSTALL the OS, they only provide an IMAGE of the OS already usable...

You could try this installer.
For the distribution scroll all the way to bottom and select unknown.
Check the box for show all drives.

Until now I was testing Remix on a flash drive, most of the stuff is running great, so I think it's time to try it on the HD.
So here's the question, it's possible to install RemixOS on HD without create partition?
I want Remix to be installed in a regular folder in my HD, with an option to select it in the OS selector when PC starts, and I want it to use data.img instead of something else... Basically just like Phoenix OS.
Is this possible?
Thx..
Cheers...

1. Download the Remix OS for PC package, which contains the Remix OS for PC ROM & Installation Tool.
2. Open the Remix OS Installation Tool and follow the instructions to install Remix OS for PC on your hard disk.
3. Reboot your PC.
NOTE for UEFI boot: press special key (F12 for Dell, F9 for HP, F12 for Lenovo, Option Key for MAC) while booting to enter boot menu and ensure that Secure Boot is disabled.
4. Select Remix OS in Windows Boot Menu.

Thanks, I already saw this...
But in this guide it's not clear what the installation tool will do, if it will create partitions, if it will format something etc... Take the USB installation as an example, I never thought it would create 3 partitions on it...
That's why I'm asking this... Besides, I saw many people unable to boot into Windows after some sort of HD installation of Remix.
Have you tried this method of installation?
If yes, how is the structure of the directory, what files are in there, is it using data.img?

The hard drive installation will create a folder called "RemixOS" and add a boot entry for it in the Windows boot loader. In that folder is the kernel, initrd.img, system.img, menu.lst and some other files. An 8 GB data.img will be created on first boot. Those who have problems with booting are typically using a third-party method to install it.

It appears that for the issue mentioned in the link you posted the solution is to simply disable Secure Boot. I don't have much experience with UEFI myself, but on a BIOS system the installer worked perfectly, it didn't break either Windows or Linux Mint.

I expanded the data.img using this tutorial (http://forum.ppcgeeks.com/android-tp2/138623-how-get-bigger-data-img.html). Don't mind the fact that it was originally made for Windows Mobile devices running Android on SD card, the concept is the same (add zeros to the end of data.img, then expand the partition table in the data.img to cover the extra space).

nope, as long as your data.img is much smaller than your actual harddisk, you will have no problems with speed.
yes, the instalation tool asks you what size you want to use, either 8, 16 or 32 GB can be chosen

I thought I would get somewhere with it but it just wouldn't detect anything...
To get things work TWRP Builder needs to create a copy of phone's stock recovery.img - what's a bootable image that is written to the /recovery partition on an Android device.
If your phone has A/B-partition layout, then TWRP Builder can''t find a partition named /recovery this because such a partition simply doesn't exist. Resume: TWRP Builder in this case isn't useful for you, you've to create TWRP at your own ( DIY ) .
To find out whether your phone has an A/B-partition-system Android installed, or not, run
Code:
adb devices
adb shell "getprop ro.build.ab_update"
If TRUE is returned, Android is a A/B-partition-system one.
BTW:
TWRP requires device's bootloader got successfully unlocked.
