Got a new Xperia X via Amazon.de . Followed the guides. Updating Android to the latest and greatest version is really a lengthy process. Then I tried to do the unlock instructions, and here comes the surprise: In the service menu: Service info > Configuration > Rooting Status it simply says "No".

Sony's web-page does not give any background about what the reasons could be if you have a "No" there. In the software info I found: Customization Version: 1302-3903_R5D Current Modem Config: /system/etc/customization/modem/amss_fsg_suzu_telefonica_uk_tar.mbn

any ideas?

does telefonica_uk uses simlock? you also could try to use the xperia flashtool and flash another customization version

open phone app and type #*#*7378423#*#* Then select Service info -> Configuration There should be a line saying Bootloader allowed: yes If missing or if saying 'no' , then it is not possible to unlock it and therefore no way to install Sailfish

Please note that SIM lock is a totally different thing from an unlockable bootloader. You'll probably find a lot of simlock-free retail devices, which may be some refurbished operator devices with an unlockable bootloader. I received one myself from Amazon.

Complain to your vendor if he sold it as an "unlocked" device and send it back.

@ghling on Amazon you mean a phone sold and shipped by Amazon? or by a third party seller (marketplace)? I did also buy a phone on amazon but the box is still sealed as I was waiting the release before installing it

Sony's instructions are pretty clear: If the service menu does not say "Bootloader unlock allowed: Yes" then you can't unlock the bootloader (regardless of the "OEM unlock" setting in der developer menu). I'm not aware of any possibility to circumvent this "security feature". I know this sucks (because I also got a locked device from Amazon and had to sent it back), but I'd rather send it back and buy it somewhere else than risking bricking the phone with some obscure "unlock method" (if there is any).

In my case, the "my Xperia" was never activated. I never intended to use the Android system. The "my Xperia" app needs google accounts and other stuff. So my conclusion -> I got a "Bootloader unlock allowed: No" phone. I will send it back to Amazon (BTW, I realized that I got it from "Smart Tech Electronics" shipped by Amazon). -- Sending it back ordering the next one. Though it feels stupid since you never know what you will get.

The whole process is really painful for the customer that wants to run SailfishX :(

I had the same problem with an Xperia X from "Smart Tech Electronics" via Amazon. I was able to send it back. Ordered the next one too (selling and shipping by Amazon).

Same problem here. Bought it from "Smart Tech Electronics" and the same issue. I will send it back. Does anyone know a shop where the boot loader is not locked? Thank you!

The problem is that Sony left out one step in their manual.

You have to start you Sony and go back to develop mode and quite close where you activated USB debugging you have to activate (allow) unlock of bootloader.

Had the same problem.

I enabled that "OEM unlocking" sub "Allow the bootloader to be unlocked" item. It must be something else

Phil_ ( 2017-10-12 23:32:54 +0300 )edit

Same problem here.

Bought device is new and SIM-lock free. Routing status says 'No' regardless of developer setting 'OEM unlocking/Allow bootloader to be unlocked'.

In Sony's unlock instructions is stated: If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

Any idea how to recover from that?

give it a try:

In fact, deactivating "my Xperia" delivers

Bootloader unlock allowed: Yes

after entering the service menue with ##7378423##

starts at the bottom of page 1 https://talk.sonymobile.com/t5/Xperia-Z4-Tablet/Bootloader-unlock-allowed-No/td-p/1052106

or this

It's worth a try to disable the "my Xperia" app and see if that changes anything (and fully unlocks the phone). But the xda link only points to some website asking money to provide you with some images that should unlock the phone!? That's what I meant with "obscure". I definitely wouldn't use such a service (and pay additional money for a feature that should be available from the start) if I can just send the device back and get a full featured one.

two things you need to pay attention for:

  1. No SIM lock
  2. No Provider Branding

The phones you are talking about have provider branding and they are not prepared for unlocking, even if it possible. Amazon or media market or similar do not sell branded phones. Ebay sellers mostly sell these kind of phones, these mostly cheaper. The mistake here is not on Sony's responsibility, providers only buy from manufactures who gave them the power to rule about the devices.

I checked the label of package and found the following numbers:

  • F5121
  • SI 1302-5472 Rev 3
  • 1SOXXBBN

Google search for "sony 1SOXXBBN" gives among others O2 product list from UK with 1SOXXBBN as an O2 product code.

Software info states: Customization Version: 1302-7210_R5D Current Modem Config: /system/etc/customization/modem/amss_fsg_suzu_telefonica_uk_tar.mbn

So the phone I have received looks like a SIM-unlocked one from Telefónica O2 UK.

Hi.

I am also having issues with locked boot loader - I was not aware of this issue when ordering my phone from my local outlet. Reading through this post, it looks like there is no way of solving this. Huh! Found this 1302-7210_R5D customization thing in the sim-menu.

So, I have more or less wasted 250$ on nothing (+the Jolla license fee)! I do not think it will be possible for me to return the phone after unpacking the hardware, ect. (not to mention the hours gone into doing OTA upgrades on the Android). Why should the dealer allow me to return the phone when there is nothing wrong with it?!

I will also use this opportunity to criticize the quality of the upgrade instructions - it sure looks like they have been written by engineers to engineers (the worst part is that I am one myself :-)). Well, I managed to get through to step 4 after reading the the guide again and again - and just to realize that I have wasted my time because of the boot loader issue. I still do not get section 1 option A/B?! Whats up with the Emma tool - is it just a short-cut to get the newest version of Android or what?

I have to admit that I am extremely disappointed being in this situation - now when Jolla finally came with a viable solution for the future...

I am currently on my second Jolla1 (bought second hand), and now it looks like I am finally done with Sailfish for good. S

Is it too optimistic that Jolla will cover my loss :-)

BR, Jonas

i guess you hve to state the fact that you want a unlockable phone

you cn try to send it bck anyway or sell it second hnd

to buy it second hand is anyway goog idea, cause then you can aSk for the proof tht it is unlockable

Try to return it. -- E.g. I returned mine. I bought it through Amazon. Though I noticed later that I actually bought it from "Smart Tech Electronics" and it was only "handled" by Amazon. However with that I can take advantage of Amazon's return policy. That is, I can give it back if you do not like it. It worked. I will get my next one in a day. From Amazon and really form Amazon.

Phil_ ( 2017-10-20 10:18:39 +0300 )edit

I'd try returning the phone. Buying a device full price at a retailer, I would expect to receive a phone without any restrictions - the unlockable bootloader of an operator device clearly is a big (unexpected) restriction from my point of view. The fact that you found out about that only now during the attempt to flash SFOS does not change that the vendor sold you a somewhat crippled device. Of course I don't know the return policy of your dealer (this may make things easier or harder), but I'd start by kindly asking to exchange the device for one which allows to unlock the bootloader (now you know how to check that).
