An example that will work, root required
1.Rename any of your favorite fonts set(a fonts set contains four fonts, normally regular,bold,italic,bolditalic
to "
VerdanaW1G.otf, VerdanaW1G-Bold.otf, VerdanaW1G-BoldItalic.otf, VerdanaW1G-Italic.otf" (your fonts can be either "ttf" or "otf", but you must rename them as the name listed above)
2.Copy all the fonts in /ebook/fonts/ to /sdcard/fonts/, then copy your renamed fonts in step1 to /sdcard/fonts/, so the orginal VerdanaW1G fonts will be replaced.
3. in terminal, type:
mount -o bind /sdcard/fonts/ /ebook/fonts/
4. then in sony reader, select the font type "Vendana"
Note: After you binded /sdcard/fonts/ to /ebook/fonts/, if connect to the PC via usb&data transfer mode, this mothod will not work untill you disconnect the usb.
And, if you reboot your T1, the bind will also disappear, so I recommend to use GScript.apk to run this command easily once after the T1 was boot up.
My question is, is there any shell to remove the bind? I typed umount /sdcard/fonts/, but get a word "failed", now I can only reboot to remove the bind.
