Short development history: by Rebellos

The project has been started by Oleg in March 2011 - development progress has been made rapidly by him, however, he had been using JTAG Riff Box to make Wave oneNAND memory organisation the same like in Samsung Galaxy S (SGS) I9000 - phone with very similiar hardware to Wave. The problem is it's very expensive and advanced stuff. In the meantime mijoma found security hole in Wave's Bootloader3 (BL3) FOTA loading code and made PoC-exploit for that. That allowed me to create, with help of srg.mstr, mijoma and b.kubica, simple Badadroid bootloader, loading kernel zImage from moviNAND flash memory - this is where port has been made bootable on literally any Wave phone. However, oneNAND layout still remains untouched and by default kernel is configured to use SGS oneNAND partitions. So nbates66 and anghelyi put all their efforts into making this method of booting operatible. It succeed after few days and ShadowAS1 had released unofficial tutorial explaining how to bring up pre-alpha Android into S8500 device. The problem was that only 1 bootloader version was supported this time, mijoma came up with idea of making our FOTA bootloader capable of supporting alot of bootloaders - he created "BL Univ Boot FOTA". Oleg became very busy with his real life stuff so kernel development practically stopped. Currently I'm the most active kernel developer, altough I'm not so experienced as Oleg is and I'm learning from scratch so it goes very, very slow.

December 2011 - KB_Jetdroid contacted me and we started to work on Jet&Wave modem driver.

April 2012 - mikegapinski has joined the project to get things together and make first really working ROM.

9 April 2012 - Mike got ICS platform booting.

Mike has stopped maintaining platform so I took it over.

Oleg has finally got S8530 in his hands and made SCLCD driver for it. Praise him!

Both S8500 and S8530 versions are semi operatible. The most complicated, annyoing, and needed driver is Modemctl+RIL.

March 2013 - World's first working non-AT commands based RIL for non-Android phone has been released. Most of the implementation was done by KB_Jetdroid, me and Volk204, basing on opensource Replicant's RIL for Samsung Galaxy S.

April 2013 I finally fixed S8530 display driver.

September 2013 - we've got working microphone recording, and shortly after Tigrouzen found a proper patch fixing voice communication during calls.

22 September 2013 - we released first version capable of multicalls.

~~October 2013 - GPRS connections are working

Currently most of the core work is done.

We are working hard with Volk204 on RIL interface, doing small progress day by day.

en very brief : there was one team , that did all the work since the start ,"the Badadroid team" , Badaroid developed by Rebellos and Volk204 was a base for Omnirom ported by volk204 which he is the main developer now , and all those rom you see is basically noob roms , they copy the work of Volk204 , they are actually no developers in the first place, if Volk204 doesn't fix the bugs in his roms , their roms has them . i would recommend

Nand - use Omni rom http://xdaforums.com/showthread.php?t=2800014

u wanna keep bada - Badadroid 4.4 http://xdaforums.com/showthread.php?t=2609560

Hero355 is also a good one but he has own bugs and he isn't around much this days , work on it stopped http://xdaforums.com/samsung-tizen/bada-android/rom-carbonrom-s8500-s8530-t2840174
