Okay, so, quick instructions for reflashing viewpad image
First, get the flash_image program (see attachment flash_image.zip
below, or mirror)
load it up to your sdcard.
Fire up ADB shell in cmd prompt. To do so, do cmd from "run..." in windows start menu, navigate via cd to wherever adb is for you, like for instance
cd c:\Program Files\Switcher\FM6F_4027\
cp /sdcard/flash_image /system/bin
chmod 755 /system/bin/flash_image
okay, that should get your ready to dump a (lame approximation of) original splash image dump.
To carry that out, first type
to find out what partitions are out there (the splash one will have "splash" in its name, duh). Note that viewsonic has the splash partition name being simply splash and not splash1 as most devices have.
On my device, the splash was mtd2
Now, let's try to back up the original splash.
cat /dev/mtd/mtd2 > /sdcard/splashbackup.img
Okay, here stuff goes weird for me because the file ends up all black (why oh why) but to hell with that, I only need it not to mess up image size.
Okay, now shut down the device and get the file splashbackup.img to your PC.
Rename it to say splashbackup.rgb565 (yes, change the extension)
Now, install Paint.NET
and this plugin
(both included in my mod pack btw)
Open the splashbackup.rgb565 with paint.net and likely the suggested dimensions will be the ones you want (might not be so for other devices, so take care. But don't worry - you can't kill the device by flashing a FUBAR splash image, so experiment bravely!)
Now, use paint.net to open a desired image in a "vanilla" format that you have likely
cooked up in Photoshop or downloaded from the web. Copy its contents to splashbackup.rgb565 and save the stuff as SPLASH.rgb565
You're almost there.
Now, download the zombiegoaste mod
of glorious splash screen creator (VibrantOwnr thx!) and rename your desired SPLASH.rgb565 to SPLASH.IMG
Put SPLASH.IMG to "Results" folder of the modified SSC
Now, run Run This Program.CMD and it should guide you through the rest.
However, bear in mind that devices treat orientation...weirdly it seems, so get ready to manipulate the original image in the program of your choice to rotate stuff (rotate sucks in paint.net) and then redo the steps above that deal with turning a vanilla image into a SPLASH.rgb565
All files attached to post and uploaded to a file sharing service, just in case.
Hope this helps folks to easily make and flash custom splash images
