Well, so far I've gathered that one can not use a2uploader to download/backup the existing FS on the T707/a CID53 phone.. but you can well.. kinda "work around" that.. by creating a customize_upgrade.xml that copies the files that you want to the usb/other folder that you later on can access by plugging in the T707 as a mass-storage device via the usb.. I found this guide and used it to extract the customize.xml file from my T707:

just hook up the T707/CID53 phone via a2uploader and browse the file system, write down the files you want copied and then add them to the customize_upgrade.xml and follow that guide.. worked for me anyways!
however.. I extracted the sv.lang and sv.t9 files for the swedish language pack from a C905 phone firmware (also R1EA030 CID53 RED) and uploaded them to the T707 tpa/preset/system/language folder.. and then I created a customize_upgrade.xml through the customize.xml I extracted/mentioned above and this guide:
how to add languages to your phone - Top Sony Forums
I then uploaded that to the tpa/preset/custom folder.. BUT after booting the phone afterwards.. I can only have the PHONE language in swedish NOT as the writing/t9 language.. does anyone have a solution to that problem? much appreciated!
and another thing.. i did not find the lng.dat and lng.lst files in the tpa/preset/system/language folder.. so I could not delete them.. could that be why the t9 does not work? and also.. i did not edit the allowedlanguage.txt file in the tpa/preset/system/language folder either.. can those 2 issues be why I've only got swedish as phone language and not as the writing/t9 language?
help please <: and if anyone has got a swedish T707 phone to extract the sv.lng/sv.t9 files.. or if anyone has got them from somewhere else.. I'd take em <;
EDIT: and yes.. I feel retarded.. it was probably that I didn't edit the allowed_language.txt file.. (my guess) because when I went through the menu->settings->general->language->writing language options I saw check boxes for the various languages.. and there it was "Svenska" ("swedish") and after I checked that "&%#%& option I could select swedish as the writing/t9 language while being in the "write message" app.. "#&%%"&"%¤&"¤%&¤"%&"¤%&"¤%& me <; just glad that I solved it.. and perhaps my gf (the phone is for her.. I'm a sinner/iphone user) might be pleased also!
