Hi there good morning all. I recently purchased an Xperia Z online C6606 the T-Mobile version. I live in Guyana so I unlocked the phone and used it. The problem is that I followed some advice and switched the firmware from 6606 to 6616 and am currently using 4.4.4. The firmware works fine however when I upgrade to lollipop I lose cell reception for some reason. I tried the 6603 firmware and encountered the same problem. I'm wondering if the baseband may be the issue however flashing that does not seem to work with flashtool. The baseband version seems to remain the same. I really want to use lollipop. Any advice?
Regards

Hi, a while back i debranded my fathers c6606 and flashed c6602 firmware for he can be on 4.2.2, i flashed the FTF using the flashtool and left out the baseband for he can still receive LTE but yesterday morning he accepted the .244 update and now doesn't have LTE. ive tried to flash the baseband of the t-mobile firmware, tried reverting back to stock, and also tried c6603 .244 but the flashtool keeps saying error flash aborted. any help would be appreciated
Thanks
Hello
I am wondering if its possible (and if so, if it works!) to flash a generic firmware on a Bell branded device (customization number 6616).
Thanks!
its possible to put a unbranded rom on a carrier branded xperia phone , without root i think it gets a little messy but it is possible... with root it should be easier
I'm looking for a workable reverse solution. I have an unlockable 6603. Can I flash 6606/6616 radio baseband and get LTE coverage on T-Mobile or AT&T when in the US?

Hi there,
I successfully installed Lolipop on the xt1068, however I haven't got any cell reception. I have the EU versio and converted it to the US international one. After this I did't have reception and I can't find any radio images...
I have all the firmwares but what are the radio images ? I tried flashing the two modem files from 4.4.4 but still no cell reception...

This should answer your question

I dont agree with you. When it updates to lollipop we do it via the ota update which checks if you are on a xt1063/1064. Then it patches the existing baseband to work with lollipop.
So I think my problem is that in the us version I had the wrong baseband already. It should be able to be fixed by flashing a EU baseband. However we don't have them yet on the net...
I've done this many tines with the Galaxy S3/4 and HTC one...
Hi, I am needing a Pre-rooted 5.0 firmware for the UK, I tried another firmware, but because I get 4G and not LTE the 4G carrier signal won't work. My phone is a C6903
Not Needed no more, new to this whole to this Rooting/Flashing. Was able to pre-root o2 UK 5.0 rom myself and flash it, it was risky as it was the first time, but found it rather easy.
So i bought this Z4 dual and it was a new phone with warranty and everything , I haven't changed anything in the device no root no customize
Running lolipop 5.0.2
No basband version, OTG not working, not receiving OTA updates.
I just dont understand why am having these issues
The phone is locked on the network, but sim is working( i have to pay a fee or they will cut off my IMEI) and wifi is working

Anyone?
Did you try it to update it with Xperia Companion in a PC? Maybe you can solve your problems with that.
Mine come with Lollipop and I update it with Xperia Companion to Marshmallow.
