[Xperia Arc Android Development] theNfan:
Hey, I just excavated my iyokan. It still has the last CM11 on it but I thought about updating to lineageOS 14.1.

Unfortunately flashing the bootimg fails:

fastboot: error: Couldn't parse partition size '0x'.

What is the cause of that? Do I need to go back to the stock ICS first or use an older fastboot? I'm really out of the loop with these things.

Edit: I found what I believe is the stock kernel in my old setup (StockPlus Kernel - .587[ROOT+INIT.D+CWM].img) but trying to flash that gives me the same error.

I can boot it with fastboot, but don't get beyond the Sony logo.

Is the old Flashtool setup still relevant?

Edit2: OK, I guess I have a better idea know what the ftf file was and how to flash it. That's not really obvious and kinda treaded as a sidenote in all the manuals I have seen.

Anyway, I guess I have the right file (MK16i_4.1.B.0.587_Central_Europe.ftf), but my old installation of flashtool won't work because it can't locate libusb. There are, as usual, endless discussions of why that is and how to solve it, but so far nothing has worked - as usual.

Is there a way around flashtool? I read you can extract the images from the ftf file and flash them individually, but trying to flash anything there will yield the same fastboot error.

Edit3: So....apparently the current fastboot does not work with the phone anymore, so you need an older version. Same goes for the Flashtool (under Windows at least), where only some older version will recognize the tft files and can flash them. And then there is the whole thing where you need to reboot Windows in some special mode to install the unsigned drivers...

Now I actually managed to install CM13.

Still there are two problems:

1. It won't properly lock into my cellphone provider. I put in the PIN, it will connect to the network, but then show a little exclamation mark and ask me to log in to the network. This brings me to some odd webpage of my provider. It should just work out of the box, it definitely did before.

2. I can't add a google account. It just hangs on "checking information" for a while and then returns.

Edit 4:

Reinstalled the ROM and this time the mini instead of the standard gapps. Took the SIM out to ignore these problems for the moment. Now I'm stuck in a loop in the setup, where it tells me "SIM card missing, Skip, Just a sec..., Checking info..., SIM card missing"...

After disabling the WIFI, I can finally skip everything, there seems to be some severe problem when it attempts to connect to Google. And to mobile networks of course.

Edit 5:

Reinstalled once more, this time using the open gapps 6.0 nano instead of the suggested one. But now the Android Keyboard constantly crashes...

Edit 6:

Now, reinstalled again with the suggested gapps.

The problem with my mobile network was fixed by manually selecting the right APN.

Still, the problem with creating the google account remains. It kinda look likes the app just closes after a moment. Could it be that it's just running out of RAM? Any way to increase that for a while? Some people in this thread have been talking about enabling swap partitions, but I did not see how to do that.

When I try to login via the browser, it will direct me to the page where I can enter my account details, but the browser will then immediately close.

Seriously, how does anyone get this stuff to work?
