Jét-Droid project
This mind-blowing development project has successfully ported Android to the non-android smartphones by Samsung S8000 and S8003
Dual boot (JetQi bootloader) preserves stock OS on the internal memory and boots into Android from the external micro SD card
Altough JetDroid project was done also for Samsung S8003, I will refer here only to S8000 as I couldn't test any of this with the S8003

HARDWARE INFO
SAMSUNG Jét S8000
"Smarter than smartphone"
With this enormous fanfare worldwide, (with the General Manager for the UK who tought that the Samsung Jet S8000 is better than the Apple iPhone 3GS) Samsung's flagship handset as of 2009, Samsung Jet S8000 was released with this not really modest marketing tag that can be found still nowadays on internet.
Yet, altough released back in 2009, the hardware of the S8000 is even as of beginning 2014 still better than many modern low-end android phones and throughout interesting target for the android porting development:

DEVELOPMENT INFO: about "JETDROID"
Target: porting Android OS to non-android devices Samsung Jét GT-S8000 (and GT-S8003)
"JETDROID": HOW DOES IT WORK?
Linux-based hardware of Samsung Jét is in general capable of booting into Android OS
Boot into Android OS is done here directly from external SD card, not from internal memory
JetDroid partition of the external (removable) SD card is formatted with Linux OS to ext2 or ext3
JetQi bootloader must be flashed on the S8000, boot into Android is possible with 2-buttons-combo
Original Samsung's firmware remains unmodified and the S8000 can also boot normally into stock OS
JETDROID DEVELOPMENT SOURCES:

INSTALL CHECKLIST:
S8000 must be unlocked (both sim and network) otherwise hard-brick by flashing of the bootloader is possible
Samsung mobile usb driver must be installed on your pc and device recognized by the pc
Compatible original firmware (list in the guide) must be flashed with multiloader v.5.62 (attached)
After that, the JetQi dual-boot bootloader must be flashed with multiloader v.5.62
External SDHC card must be inserted in the phone (the faster SDHC card is, the better)
Card gets formatted by running Samsung OS with Ubuntu/Linux OS (running Ubuntu in the Virtual box or as "Test Ubuntu" (live CD) is also possible)
Unmount TFLASH volume (careful here, as MFLASH is internal partition of the stock fw of your phone!!!!)
Better use "Disk Utility" than "Gparted" to format the SDHC card and format first partition as "Master-Boot-Record" (ext2) for JetDroid ROM
JetDroid partition size for JetDroid can be between 1550-1950mb, create another partition (rest) as FAT
Mount both volumes/partitions (ext and FAT)
Extract in Ubuntu downloaded ROM and paste all files on the JetDroid partition
In "Terminal" (Ubuntu) set permissions: (sudo chmod -R 777 /media/yournameforjetdroidpartition(withoutspaces)
Now "Safely remove parent drive" (phone) and switch off the phone
Boot with 2-buttons-combo into Android OS (call&power buttons)

State-of-the-Art ROM for JETDROID
NOTE: my own reccomendation is to use only the very fastest SDHC cards you can get. Don't even consider anything beyond Class 10, otherwise you will face unstable and laggy performance. Sandisk extreme 80Mbps will work the best.

Out of my own experience, I can report here only of four ROMs that I was able to boot on my S8000. Regrettably, I have missed whole this exciting development project although I own this phone since 2009: I simply never browsed in internet, couldn't even imagine to boot into Android OS with it. If you ask me "is it worth it"? I will say: yes, definitely! One can use Samsung's TW2.0 for calls, SMS and mobile internet and Android with WLAN. It is matter of taste, I really enjoy to use Android with my Jét, especially my favorite ROM, the CM7.1 by Carlos_Manuel

JETDROID ROMs - functionality comparison:
Eclair 2.1 (JetPlatform0.2 and 0.3)
ADB: NO
WiFi: NO
Bluetooth: (send & receive) NO
Root: NO
Touchscreen: YES (fully working)
Google (Play Store / account sync etc): NO
Apps: YES, at least all of those you can install
Android version features: YES (languages, etc)
Functionality: unstable, laggy, freezes often, no tone (indication works)
Comment: despite just few working functions, developing of this ROM was simply the revolution in person and excellent base for further development. A key-feature (JetQi bootloader) was invented short before this stage. Reportedly, Wi-Fi was working on 0.3 platform, however I wasn't able to turn it on, or I have used wrong files on my SDHC card.
CyanogenMod 6 (Froyo 2.2)
Unfortunatelly, I wasn't able to boot this ROM. I've tried all tricks but the ROM I found and downloaded simply didn't boot. I am grateful if anybody gives me a hint where to download working one.
CyanogenMod 7.1 (Gingerbread 2.3.7)
ADB: YES (everything works: push/pull, installing apps, logcat, permissions changing etc)
WiFi: YES (fully working)
Bluetooth: YES (fully working: send & receive)
Root: YES (I've gained root access it with the SuperOneclick 2.3.3 root tool by Shortfuse, that uses ADB to install Superuser and busybox)
Touchscreen: YES fully working
Google (Play Store / account sync etc): YES (all working)
Apps: YES (all apps work here: no matter if root or no-root ones)
Android version features: YES (all working)
Functionality: altough slow compared to modern devices, with fastest SDHC cards it is stable and not too laggy, it makes definitely fun to use it. Not so with slower SDHC cards: unstable und laggy, CPU gets warmer then.
Comment: overall best ROM that I could try. If some day a Jét-driver for the SIM card get succesfully developed and some recent Linaro codes implemented in the kernel to boost its performance, this ROM would be just perfect for the S8000
CyanogenMod 9 (Ice Cream Sandwich 4.0.4)
ADB: YES... (not fully, installing Apps via ADB works, read comment)
WiFi: NO (freezes)
Bluetooth: YES (I didn't try data transfer)
Root: ALMOST (read comment)
Touchscreen: ALMOST (cursor circle works, also click, but not "hold" click, therefore difficult scrolling)
Google (Play Store / account sync etc): NO (no Wi-Fi, no SIM card, so no connectivity)
Apps: YES
Android version features: YES (multi-languages, time zones, correct time displaying)
Functionality: early development stage, tough obviously great potential for the S8000 in ICS, hopefully it will be developed further
Comment: with this ROM as-is, ADB was working, but it wasn't able to install apps. After just a simple experiment of copy&paste of few files from the CM7.1 ROM (cat, getprop, sh) I was already able to install the Apps and nearly gained root access. Some basic files are missing in this ROM that is bit left alone in its early stage of development (ADB reports: rm not found so it can not delete the files). This ROM has potential to be great and should definitely be developed further, the device benefits of ICS codes, feels smoother and fast.... you can see that it boots into OS about 7sec faster that CM7.1, altough it has a slower SDHC card (about 20% slower). So ICS could likely be "The One" ROM for S8000, by gaining all functions that CM7.1 already has working. I didn't try to create logcat for Wi-Fi enabling, maybe it would give an answer what to do, it is anyway nearly working....

Nice!
But credits goes to Dopi and KB-JetDroid from jetdroid.org / Github.
My built ROM is optimized and includes some other stuff like librsjni file for live wallpapers, etc.
Hopefully someday Dopi and KB-JetDroid starts working on ICS, because it's fast on Jét.
@Carlos_Manuel
OK, I will update the OP under "credits" altough you definitely deserve them as well: I couldn't even find anywhere GB roms by dopi and KB-JetDroid and some of which I found and downloaded didn't boot

Thks for opening this new thread Tetakpatak
I think i'm going to dust off my jet again.
My resistive touchscreen just died on me... cant play with my jet anymore...
Will remember this one as one of the best cellphones i had... shame that samy did.not used android on it.
Sent from Asus MemoPad FHD ME302C
Oh, pity..... I'm sorry mate
I also really like my S8000. It runs whole day long as radio (app Live365) on Carlos_Manuel's CM7 Android.

I'm trying to get one 2nd hand on Ebay... but since the touchscreen is resistive i'm kinda reluctant...
I was able to remove the "digitizer" from the phone (not glued to the screen) but replace part are way too expensive for me to just tinker with the Jét...
I really liked my jét even if was just to tinker with... One of the best buys i did.
Your phone didn't get broken because of flashing a JétDroid I hope?
The back part gets quite warm, reading a SDHC card costs CPU hard work , it seems.

No of course not.
The digitizer just stop working on most parts of the screen... and its the resistive layer fault because if i press it really hard sometimes it works... its was to expect after all resistive tech like this have a limited number of uses until it "breaks".
2nd hand models are quite cheap on eBay but i wonder if the digitizer is in good condition, since i only need that part to reassemble my good old jét...
Good luck

This phone is fantastic, I have one that is indistinguishable from brand new hardly used, it's a new replacement for a digitizer problem , I have never stopped hoping this push would come, there are millions of us who still have this phone, I hope what your doing is advertised widely. Pity samsung didn't release the source code they've missed a massive chance to increase their Street cred with the whole tech buying public and change public perception of their support. Might not be allowed, but I bet many would give a small donation for a fully completed modern rom. Best wishes from me and from many.

I totally agree. The hardware is really good and sturdy, so with the source code, dopi & co would probably easily port ICS similar way like in Badadroid project (with Samsung S8500 and S8530 with Bada OS, last model between S8000 and the revolutional Galaxy S1, i9000) instead of taking the hard road of hardware hacking.
Boot of Android OS from the external SD card slows the phone massively down, as the card slot is a bottleneck.

Ola. Mi Castellano es muy limitado. Lo espero que entiendas Inglés.
This project, as far as i know, was abandoned years ago :/ ... as i recall it does not the cell network chipset (i might be wrong here, i was a few years ago) but i think WiFi was ok and working.
The resistive part of my Jet unit died last year and i just trashed the unit so i cant really test it now. Hope the info helps.
Yes, exactly. Wifi works, not so the mobile network in Android. One needs to reboot to the stock UI to use mobile networks. I still have my S8000 and both android and stock UI are working.

Hi there, I know this is an old thread, but I'm planning on installing it to my hibernative Jét S8000, and was wondering myself if there is a way to extract Sim relative stuffs from Stock Samsung OS and implement it to JétDroid Rom? A question just like this cause, I saw that pretty all of the JétDroid Roms have a problem with Sim, so, is there any way of doing so??
Anyway, thanks for any revelant- or normal- answers,
See ya

Well, AMAIK, the development project described in this thread was the only succesful porting of the Android to the S8000, running it from the external memory card.
None of the ROM versions has ever made it to work with the SIM card if the S8000 was booted in Android.
