G8142_1308-8226_45.0.A.7.137-R5A_Customized_CE1.ftf extraction error

Hello, I have downloaded G8142_1308-8226_45.0.A.7.137-R5A_Customized_CE1.ftf from Xpericheck (alfafile.net host) but somehow I am not able to extract this ftf witn 7zip (and with WinRAR). It gives me an error so I am not sure if package is corrupted (doubt it). SHA-1 checksum of ftf is 45772ad09c580e282c48f5a3eb91fb38e06a57cd. Could somebody tell me how to extract it, pls? Thank you in advance.

There is no way to create .ftf for Xperia XZ Premium, XZ1 and XZ1 Compact, as Flashtool doesn't support this devices (yet?). Meaning that it is created in "generic device mode".Coz of that it may be broken.

 

Not sure why they are adding "working" ftfs for this 3 devices... I think it's somekind of clickbait and, as You need premium to dl files over 1 GB, way to make money?

I don't understand it either. But flashtool is not official Sony utility, right? Even if it was, it wouldn't make any sense of giving us broken files like that.

No, Flashtool is not official utility, but .ftfs are not Sony's thing either, they're archives made by Flashtool.

 

The problem with XZ Premium and XZ1/Compact is that they uses new flashing standard. Because of that Flashtool doesn't support them. Additionaly their firmware is built differently than other Xperias.

Because of that, Flashtool has no way of creating working .ftf with firmwares of this 3 devices, but still there is possibility to autocreate the .ftf, which doesn't mind flashing standard or if Flashtool supports the device. And coz of that there could be created broken archive.

 

Than as there is no .fsc sript for XZ Premium or XZ1/Compact, so there is no way to check if .ftf is OK. At least no other way than trying to unpack it manually.  They (who upload it for Xpericheck) have a lot of firmwares to upload and checking every single one of them would take time, so I don't think they saw a need to check it... 

 

However do You really need CE1 firmware? There are .137 from other regions (not made by Xpericheck) and You won't see any differences when using it.
