1 - There is NO AsusUnlockLangID.exe for Asus P735 - do not know why.
The one from P535 or P525 is useless on this phone.
2 - Great point about "same-upgrade-tool-language-possibility" yet the official ROM comes in an .exe file that i do not know how to unpack/hack in order to insert the correct ROM or vice-versa.
Could you provide me with some insight for that?
3 - Besides that, do you think a tweaked P750 ROM could work on this phone, or a hybrid P535/735? Wouldn't that be the best/easiest solution, which would in the same way finally create a more advanced ROM for this quite neglected device? The older P535 has even 6.5 ROMs whereas P735 is limited to the basic 6.0. (Does that have any advantage by the way?)
4 - I am open to any way of flashing, given it provides the right result so all your advices are welcome.
