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



NEW DEVELOPERS ARE WELCOME

GET A JETDROID DEVELOPER !!
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:BUILD A ROM - DEVICE REPOSITORY SOURCES:DEVELOPMENT STATUS (to early 2014):
  • modification of the JetQi bootloader is possible for succesful porting of the CWM recovery
  • drivers development necessary for enabling SIM card functions (calls, SMS)
  • State-of-the-Art ROM: CyanogenMod 7.1 (build 20130603 by Carlos_Manuel: DOWNLOAD IT HERE)

Prompt Flashing guide
FLASHING GUIDE

Quote:

DISCLAIMER:

Code:
* i am not responsible for any bricked devices, marriage crisis,
* sleeples nights, termonuclear wars, electricity blackouts, short
* circuits, or for bad weather in your region that will brick your phone.
* this thread is for an older device, download links may dissapear by time
* warning: bootloader flashing is just always risky proceeding that
* could hard-brick any device. Everybody is flashing on his own wish- and risk

Quote:

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
Quote:

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.

JétDroid: ROMs overview / earliest to latest
Quote:

JétDroid and me: pros & cons
At this point, I will just report my own experience with all other ROMs that I was able to try so far on my S8000
* * * * * * * this comparison is therefore just subjective and by no mean a fair or complete overview * * * * * * * *




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.

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.
