Firmware update only

Murdock — Tue, 27 Nov 2012 00:51:30 GMT

Hi!

My phone have the 6.0.B.1.564

Can i upgrade only the firmware?

Last weekend have repaired the phone software but the problems persist... MM#3 error: no sim card, bluetooth bad sound using handset or the bluetooth in car system (lot's of distortion and echo), esporadic reboot's (occurring at irregular intervals), small crackles from the speaker when the phone is ringing, etc...

In Sony site the latest available software is: 6.1.1.B.1.10 but my carrier didn't aproved the ICS, is waiting for another version, they said this ICS have lot's of bug's, worse than Ginger Bread (2.3.7).

In OSX the Bridge software don't repair the phone, waited 1 hour and don't pass the second screen.

In Windows 7 the repair worked but i casn't upgrade the firmware, why?

By the way, ICS improved better quality pictures and HD movies?

My old Nokia have better image and is 5 year's old...

p.s. - the JB is to come or another year in the wainting line?

you just said it yourself your carrier/network hasn't approved the firmware update.

there isn't news on JB so far just that it's under testing, that's not a yes the Xperia U will get it, and that's not a no the Xperia U won't get it.

if you don't want to wait for your carrier to approve it, here is an alternative.

not quite, read this:

From sony mobile developers

Warning! If you perform this step, you will unlock the boot loader.This may void your warranty and/or any warranty from your operator. If you still want to unlock the boot loader of your phone, enter fastboot.exe -i 0x0fce oem unlock 0xKEY, where KEY is the unlock boot loader key you got in the beginning of this instruction. The boot loader should now be successfully unlocked.

Warranty Document

http://www-support-downloads.sonymobile.com/common/warranty_phones_US_12.pdf

Nor does this warranty cover any

failure of the Product due to accident, software or hardware

modification or adjustment, acts of God or damage resulting

from liquid

Update:

For most issues/problems, unlocking the bootloader voids the warranty. Sony Mobile only honors the warranty if it is a known issue in that model/batch of phones or if it is an issue that clearly could not have been caused by flashing a different ROM. Because a new ROM can have a wide range of consequences (e.g., it can overheat the battery or change the voltage, which can damage other components), that basically means that only a small subset of issues are still covered by the warranty. Therefore, even when the phone is in warranty, the service center usually has to do a very costly board swap in order to get the phone back to its original state before it can perform any repair. The end-user has to pay for that part of the repair.

We are proud of providing the unlock feature to the developer community. Previously, there was a large risk of bricking the phone when unlocking with third party software. Sony Mobile’s solution remove’s that risk. When we initially provided the unlock feature, it was presumed that only highly skilled developers and super-users would take advantage of it. From blogs and discussion boards, it was clear that the community understood the risks and that unlocking largely voided the warranty. It appears that less sophisticated users (despite all our warnings) might be using the feature, and are now surprised by the consequences.
