[XPERIA X8 General] darkfrmr:
I don't remember exact dates but this is what I remember to have seen on this forum since january-2011 (a little research too):

X8 Development History (summary).

:)

- To get root access, downgrade to 1.6 "Donut" was a must.

- zdzihu created xrecovery for x10mini based on cwm recovery sources (that's what we used until cwm recovery was ported to the x8).

- racht started porting eclair AOSP roms and then HTC Sense roms, Eclair and Froyo, part of HACKDROID rom series.

- racht started porting early versions of CM7, part of HACKDROID rom series.

- Jerpelea, now known as FXP, started FreeXperia development in x8, bringing CM7 with libs from sources.

- Somewhere in time it became posible to root 2.1 eclair, and custom roms were pre-rooted.

- JIT appeared for stock 2.1.

- Blagus started "Bootloader unlock" development (it took months to achieve...).

- First try to port a Froyo MIUI by as-mario (now XperianPro), sadly it never worked fine and the project was abandoned. There wasn't sources available to properly port it.

- doixanh (later known as "module man" lol) surprised everyone extending capabilities of stock kernel by using kernel modules, synaptic gesture, overclock, undervolt and also he fixed mddi lags (at this moment it was unknown that there were 2 version of x8 with different digitizers).

- Somewhere in time (lol) ponanovn started porting nobodyAtall's MiniCM6 for x10mini (Froyo) and it became the first really stable rom because it has fixed some issues with random reboots and "super user" apps making device to reboot.

- SU apps reboot fix was ported to almost every rom like HACKDROID Floyo (Froyo) and Gingerbread roms. Froyo roms were pretty good and almost perfect for day to day use. Gingerbread roms lacked camera and fm radio, and there was battery issues with them.

- doixanh started his new project "FroyoBread", Froyo with "good looking" features from Gingerbread like crt screen on/off animation and edge glow and it was created from clean sources, but based on racht's work on HACKDROID Floyo to make everything work. This became the greatest Froyo release, even today there is people using it's latest version. FYI latest versions of HACKDROID Floyo were based on FroyoBread.

- ponanovn ported x10mini's MiniCM7 from nobodyAtall (in this point gingerbread roms had vga camera only, from jerpelea's FreeXperia sources).

- kuyagaol created a new CM7 rom, kuyadroid, based on HTC Legend nightly's, it combines HACKDROID CM7 and MiniCM7 to fix fm radio and bring vga cam.

- AnDyX appeared on the scene and brought us new modules, including real dual touch for x8's with cypress digitizers, force disabling automatic brightness, netfilter and smartass governor.

- Final version of FroyoBread released, doixanh started a new project called "GingerDX", FroyoBread exclusive features in a CM7 HTC Hero nightly's based rom. GingerDX was the first Gingerbread rom with fully working camera (the trick was later ported to every CM7 rom). With GingerDX release appeared a lot of "new developers" (soft modders or rom cookers) who created modded versions of GingerDX (even to this day), adding fake features like Bravia Engine and Xloud, but mostly theming framework and tweaking it.

- A bad day for x8 users, racht silently quit development with his last port of an HTC Sense rom.

- With a nearly completed CM7 rom from sources, jerpelea, now FXP, left x8 development, but now some components libs could be built from sources, like Wi-Fi, making easier to port to another android version.

- The most active developer on that moment, doixanh, couldn't continue developing cause he had no x8 anymore but thanks to forum member "deedii", who organized a sucessful "donate to doixanh" thread and motivated people to support doixanh, he was able to get another x8 and continue developing GingerDX.

- x8 development was almost ending, rom updates were each time less frequent but suddenly the forum member the_laser achieved one of the least possible things, the x8 bootloader could be unlocked now! take that SE!, this revived development and custom kernels began to appear, some of them based on FXP kernel sources (FXP was silenty making that).

- First custom kernel: LinuxDX by doixanh, improving perfomance and moving modules to the place where them should be, in kernel. (discontinued).

- New custom kernel from alfsamsung, Alfs Kernel for GingerDX showing us the real potential of x8, great performance improvements. (with frequent updates is used by a lot of users today).

- nobodyAtall (nAa) started x8 development with MiniCM7 and nAa kernel series (based on stock kernel sources) combining stability and good performance, with most of the core component built from sources (FXP's way). A lot of kernel components were ported from newer versions of it. New features in this combo like native wifi tethering. Very popular rom like GingerDX.

- Forum member XDA-RK creates an updated version of FroyoBread called FroyoPro, latter it becames maintained by member lrakkarl.

- lrakkarl makes a patch allowing froyo users to use custom kernels, especially Alfs Kernel.

- Bad news for some users, devices manufactured past week 29 on 2011 (11W29+) can get hardbricked if they attemp to unlock bootloader, forcing them to stick to stock kernel, apparently SE fixed the security hole that was used to bypass bootloader, on newer devices.

- Achotjan bring us Sony Ericsson Debrand Engine, and we had a taste of what it would be an official gingerbread update from SE.

- First tastes of AOSP Ice Cream Sandwich ICS began to appear thanks to forum member troufiniou, stock and custom kernel, pretty buggy and not for daily use.

- paul-xxx started developing CM9, only for nAa kernel. Few bugs with wifi and camera and HW acceleration not working.

- MIUI sources are released. First ports, by JahlovePL, are based on paul's CM9. A new version comes, MIUI gingerbread based on CM7 rc2. They have few bugs and are not fully translated from chinesse.

- doixanh is not longer available to support GingerDX, B.Jay and eagleeyetom continues "the fun".

- djnilse starts to build CM7 version of alfs kernel, for roms that have wifi built from sources like MiniCM7.

- nobodyAtall, with new adreno libs from qualcomm creates MiniCM9, almost fully working ICS rom with HW acceleration, some issues and not working camera. For this a new kernel showed up, nAa ICS kernel based on nAa kernel. Due to this paul-xxx quit developing.

- nobodyAtall's ICS rom MiniCM9 is almost bugfree, camera was fixed. The only bug left is not working HW encoding/decoding due to missing OpenMAX OMX codecs for ARMv6.

- TeamFun (doixanh, B.Jay, eagleeyetom and djnilse) releases IScreamDX, CM9 source based rom. It uses nAa ICS kernel.

- JBMiniProject releases new android version JellyBean based on CyanogenMod 10 sources.

- nobodyAtall stops development of MiniCM7 and MiniCM9 and releases MiniCM10, CM10 (JellyBean) based rom with only HW Video encoding / decoding not working.

- nobodyAtall makes old OMX libs to work on ICS and releases MiniCM9 3.0.5., a fully working ICS rom with HW Video encoding/decoding finally working so no issues remaining on camera.

- nobodyAtall release MiniCM10 4.0.2, a fully working JB rom with HW Video encoding/decoding finally working so no issues remaining on camera. This release makes xperia x8 the first msm7x27 device to have a fully working Jellybean rom, a really great achievement of nobodyAtall.

- nobodyAtall gives to our x8's more power upgrading his 2.6.29.6 jb kernel to 2.6.32.60 version.

- Development of GingerDX is now stopped/discontinued, the last version is v031b.

- X8 section in forum is moved to "Legacy & Low Activity Devices" section.

is SE x8 development reaching its end?
