[NOOB] - Xperia Z Q&A, Help & Troubleshooting

Hey i am totaly new to sony phones and have always used samsung, i am looking to by a c6603, my question is: what are the changes that i can't unlock my boatloader, and why would sony make 2 versions of the same model c6603. Are the international c6603 always unlockable or not?

Unbranded phones purchased off contract will have unlockable bootloaders.
Carrier branded phones supplied by your network provider usually, but not always, have a non-unlockable bootloader.

[Q] Xperia ZL in Japan

It looks like Xperia ZL is not launching in Japan? Anyone knows if its true?
Don't even see it in their products lineup!! i'm looking forward to ZL and not Z
http://www.sonymobile.co.jp/product/
Sony's released plan of the devices is messed up. Everything they said on their announcements didn't come true. And yeah japan should also recieve Xperia ZL as sony did mention that both Xperia Z and ZL will be available on all southeast asian countries before european countries gets it. But look what's happening now. Europe has already demo units and released Xperia Z now but on Southeast Asia only japan got the Xperia Z release and only singapore got a demo unit with them. Rest of Southeast Asia has no news whatsoever about these devices. And yeah my most anticipated device "Xperia ZL" looks like got left out of the dark now also.
Will the ZL released in germany?
Japan.
Yeah.... no news from japan...
I think buy the sim free version from the net, n use it with the Japan's line is the best choice....
well...

That will be great except even with a SIM Free phone you need to have the IMEI registered by Docomo to use it, and they won't register any device they haven't sold.

yup.... so we need to go to docomo to register the ZL IMEI id...
Didn't know Japan is that harsh here in Singapore, it's illegal for the carriers to lock the phones

[Q] Flash kernel and ROM between C6602 and C6603?

Hi everyone! I'm planning to buy a Xperia Z next week. The problem is, as you guys already know, the Xperia Z have two version: HSPA+ (C6602) and LTE (C6603). Currently, mobile phone distributors in my country are selling both these version, and the LTE one is 100$ more expensive. Of course I want to buy HSPA+ version, since my country doesn't have 4G yet. But can I flash C6603's kernel and ROMs to C6602?
What part of "No questions in General" was hard to understand?

i am currently faced with this same problem..i send a PM to an Xperia dev on XDA who told me it is ok to flash firmwares between the C6603 and C6602 to access the frequency bands with no problem.

International vs t-mobile version

Are there any pros/cons?
I got the t-mobile version specifically for their new jump program, but realized that the Sony style store carries the white xperia z compatible with t-mobile. Not sure if it's worth it to pay restocking fee and get the white one if that is the only difference (color)
How many more T-Mobile threads do we need.

I have the white Xperia Z 6602 unlocked International model which I'm using on AT&T. The biggest difference is that you cannot pick up LTE bands here in the United States. Not even the 6603 model. What that unfortunately means for us USA users is that we will not be able to get Voice over LTE which probably won't be wide spread for at least 6 months to a year. I don't mind either way, not enough phones support it yet but I'm sure in the future we'll see more of this technology.
The only difference in the USA between the C6603 and C6602 is that the C6602 will get fully hspa + on att and tmobile where the C6603 what I have only gets it on att period.

[Q] Cannot find a working link for an EE UK 6903 FTF

As the title plus Xperifirm mentions TMobile UK and the others for the C6903 but no mention of EE UK.
Thanks
T-Mobile and Orange are the same as EE.

I know, but other manufacturers often name their roms EE. It seems in this case the T-Mobile UK rom is also the EE one

Question about the bootloader for the S8 (T Mobile)

So I am looking forward to buy the S8 and I do want the unlocked bootloader. I heard that if you buy an S8 or S8+ from T Mobile then you get the U variant instead of T. Is it true? Because as far as I know the S8 and S8+ US variants got the U after the numbers which shows that the bootloader is unlocked.
T-mobile bootloader on the s8/s8+ is locked

Every North American model is the U model, simply with different firmware. Whether you buy a carrier version or the US unlocked model (U1) they are all quite literally the very same U model. This means you CAN do carrier switching, with some work (for instance, install firmware from T-Mobile on to an unlocked model, or Verizon, or whatever) - this DOES NOT however, SIM unlock the device. There was misinformation on the internet that the model numbers would be like they were in the past, but it's not true. If you buy a T-Mobile model, it's the G950U, just like it's the G950U on Verizon and all other carriers (no longer are there "T" models, "V" models, etc). The unlocked model is the G950U1, but it's still the very same model, so the firmwares are interchangeable.
Currently, there is no known way to unlock the bootloader. As of this week, root is available (with some caveats), but no way to unlock the bootloader. The only models you can do that with are the international Exynos models, and the more rare Hong Kong Snapdragon model. I sincerely doubt we'll ever be able to unlock the bootloader, but I'd love to see the XDA community make it happen.
Damn, I guess the International version is better.
The U = carrier unlocked. Not unlockable bootloader. Besides most glass Mashers and text-while-driving people don't even know what the heck a bootloader is lol
Bootloader ? oem
I have been thinking about get a S8+, now my wife's S7 phone and tab S2 tablet you just go to developer options and turn on oem unlock dose the S8 not have that?

So what you are basically saying is, 950U s8 models even though unlocked can only be used on other US carries and not internationally??

No, you should be able to use the U1 (North American implied variant) internationally, mostly without issue. I believe it supports most, if not all GSM/LTE bands (CDMA may be a different story). I was just saying you cannot unlock the bootloader on the North American models... Different than SIM/Carrier unlock
