I have been holding on to my original jolla all the time, but I am getting tired of its slow responsiveness. I have hardly followed the discussions about xperia, so please forgive the stupid question: can I just buy any old Xperia X and transfer my sailfish on it? Do I need another licence?

you have to buy a new license for 50€ - you cant transfer it. model f5121 is officially supported. model f5122 is useable too (for advanced users). the official support for f5122 should come in the near future.

Thank you that was quick! I imagine that the difference in performance between the jolla and the xperia will be big. Is the difference between 5121 and 5122 also important? I would think (hope) that I am "advanced" enough to get sailfish running on the 5122...

f5122 is the dual-sim-version. if you use the second sim-slot, you cant use a sd-card.

There are some facts you have to keep in mind:

  • License: As far as I know, you can't transfer your SFOS License from a Jolla 1 to an Xperia X. You'll need to purchase a "Sailfish X" license from the Jolla store.
  • Device Model: When buying an old Xperia device, look for the model number. Currently, SFOS is only officially supported on the F5121 models (single SIM Xperia X), though unofficial support for the F5122 (Dual SIM) exists and should become official in the future.
  • Bootloader: An important requirement for the installation of SFOS on an Xperia device is the possibility to unlock the bootloader. If it is locked (which mostly is the case on provider branded devices), you can't install SFOS on it.
  • File / Settings transfer: As both devices run the same system, it should be possible to just copy over all files and settings. However, it is usually a good idea to start fresh and only copy / import important stuff. This way, you can get rid of old files and apps no longer needed and have a clean system.
  • Android Support: On the Xperia X, AlienDalvik (the support for Android Apps) runs on a slightly newer version of Android (but still on the 4.4 branch due to changes in newer Android versions). There are a few reports here on TJC that some Android Apps running fine on Jolla 1 devices causes issues on the Xperia X.

I hope this covers your main questions. If there is anything unclear, just ask.

excellent, thank you for the detailed comments. Looks like I should be looking for a good and unlocked 5122 then. I assume there is a thread somewhere in these fora about the possible complications of the 5122 installation? And for the file transfer, I should be able to use the SD card for it, I imagine. I remember that I had great difficulties getting the SD card usable on the jolla, years ago - I hope I do not have to go through all those loops again on a new device.

Switching the sd card over from your Jolla 1 to an Xperia X could be tricky. The Jolla 1 uses BTRFS as file system (I think for the sd card as well), while Jolla switched to ext4 on the Xperia. One of the recent updates brought BTRFS support to the Xperia, but as far as I know it is not enabled by default. So check which file system is used on your sd card before moving it to the xperia. Or better prepare to copy the data to a safe location, format the sd card in the xperia and then copy it back onto it.

There is a thread here regarding flashing the F5122 here: According to a post on TMO, the adaptation comes down to editing some files and installing the package for multisim support (see ). However, I don't own a F5122 and didn't follow this topic, so it can be different by now. What I can tell you is that the official flashing script from Jolla included hints towards official support of the F5122 from the beginning.

Oh, also keep in mind that you can only use either a second SIM or the sd card on the F5122 since they share the same slot.

very helpful, thanks.

Besides the dual sim, does the 5122 have a particular advantage (for a "business user", I don't watch movies or play games on my phone) over the 5121?

wcr ( 2018-04-07 11:45:45 +0300 )edit

No, the F5121 and F5122 are pretty much identical apart from the Dual-SIM support on the F5122 as far as I know.

ghling ( 2018-04-07 11:48:54 +0300 )edit

dual-sim F5122 has twice more memory (64GB)

Just want to report that I found the responses above extremely helpful (thank you). I bought a well-kept 5121 from someone and flashed it successfully. Most things I need are now running well, much better than on my nice Jolla1.

I need to specifically mention the extremely straightforward recommendation in which worked also for the xperia and gives me great continuity.

It was trickier to re-install syncevolution which I use for syncing my contacts against memotoo. I also struggled to transfer the full whatsapp-history but it did work in the end.

Congrats, good decision to support the development of this ecosystem.

Honsetly I would wait until the 2.2 Update is out. The actual version om Sailfish X is too bugy! Connenctivity issues, camera issues, sound issues, SD-Card issues, Android app support crashes more often and a laggy interface in some native aps would be my reason. The last update ( made it even worse. So now even my unsharp camera stopt working (Black screen). But in general without those bugs it is great to have updated Hardware for Sailfish.

I can only report that my experience (with is the exact opposite.

I have not seen anything I would consider a bug. The Xperia connected easily to not only my home wifi but also my work wifi as well as eduroam. It absorbed my sdcard very smoothly. When I loaded gigabytes of music onto that, through rsync from my home server, it took only seconds for the phone to find the music. I have taken a photo or two which look nice. What else would I want?

I think when the next update comes, I might be reluctant to install it, since everything works so well.

I am still sad to let the old jolla disappear in a box, but really none of these things worked smoothly on it anymore.

By connectivity i mean mobile network.

Raymaen ( 2018-04-13 17:04:28 +0300 )edit

works well too here.

There are definitely a few bugs/glitches in the experience up to, but we're talking about 90% happy 10% annoyed. Still totally worth it.

Another little update: the upgrade to sailfish 3 went well as well, with the exception of syncevolution which no longer installs. I used to use syncevolution to be able to synchronize my large addressbook with memotoo. It appears as if native carddav synchronization now works, but a severe limitation of that is that nobody seems to know exactly how it synchronizes, what happens in the case of any errors, and generally what is going on during the sync. Except for that, everything works very well.
