Stragulus' FT2 SD Froyo port process (How To)

UPDATE: Froyo port to NAND flash now available HERE

IF you still want to run Froyo from sd be sure to get the pointer calibration file located at the link above and insert into the appropriate location of the files below. Note: If you don't know where or how to insert the pointer file you should just flash the FT3 to NAND.

If you don't understand what you are doing/how to do it then you should probably wait for a simple sd card install. This requires the use of a lot of different tools that everyone may not have/understand. Read through it all before you start the process. Neither I nor anyone else referenced throughout take responsibility for anything that happens to your tablet. In other words, PROCEED AT YOUR OWN RISK.

I hope to have an sd card install worked out soon so anyone not in a hurry may want to wait. I also think I have a clockworkmod recovery process (read: Backup) worked out so anyone that does want to try the below or an sd install can have a backup to go back to if all doesn't go well (and sometimes it won't).

People that know what you are doing (you know who you are) please feel free to respond if you see error in my delivery. I am just trying to clean up the process around Stragulus' outstanding work (he has a Donate button!) spread out over many many posts. Feel free to "Thank" me if this write up is useful to you.

-Download necessary files-

Download Flytouch 3 files (using this google cached page of download link):

http://www.google.com/url?sa=t&sour...E78SDFbJd121Gfftg&sig2=jBjp0lQBhebR0Q5vgAUChQ

*Rename firmware-discovery to .zip, open (thanx for the catch kineticz)

Keep system.tar and ramdisk.img

Download updated kernel (uimage) and wifi driver here:

Keep uimage and rt2070sta.ko (wifi driver)

-Set up tablet to run Froyo from sd card-

Use WinHex or WIN32DiskIMager (free) to make a bootable sd card using bootable sd .img from second link in this post:

http://xdaforums.com/showpost.php?p=11830573&postcount=1504

Put uimage and ramdisk.img files on sd card

(you may have to format entire card (705MB) FAT32 to drag/drop files to it)

Put sd card in tablet, turn on.

Let it burn kernel and ramdisk

OR

Use burntool

(ignore firmware files)

-Set up sd card for running Froyo-

Partition all of your sd card back to FAT32 (Easus Partition Manager for pc is free)

You will now create a total of 6 partitions

First PRIMARY partition (empty): Format this as fat32

Second PRIMARY partition (will become /system): Format as ext3. Recommend 192MB size

Third PRIMARY partition (will become /data): Format as ext3. Use rest of space, BUT leave 256MB for last Primary.

Lastly create another PRIMARY partition of 256MB: Format as FAT32

Select/highlight the PRIMARY partition created last (256MB). Right click/choose to create logical partition WITHIN it.

First LOGICAL partition (will become /local): Format as ext3. Recommend 128MB size

Second LOGICAL partition: Format as fat32. Recommend 128MB size

-Copy system to sdcard-

Plug tablet into pc/mac using usb cable

Using linux enter the following:

sudo mkdir -p /mnt/system

sudo mount -t ext3 /dev/sdX2 /mnt/system

sudo tar -C /mnt/system -xvpf /path/to/system.tar

(/path/to/system.tar is location where you have the system.tar on your pc/mac)

-Fix wifi file-

While tablet is still plugged into pc/mac

Using linux enter the following:

sudo su -

export SYSROOT=/mnt/tmp

cp rt2070sta.ko /mnt/tmp/lib/modules/

REBOOT TABLET

-Root with Universal Root 1.6.2 beta 5-
