I have two Jolla 1 phones. One is old and works quite slow despite of removing unused apps etc, etc. The second one is much more recent (end of 2016) but is has a broken screen. Is it easy to exchange screen in Jolla1? Has anybody done it?

Hi All, thanks for answers. Finally I did the job. Actually I was missing the right tools, this T5 screw driver. Once I got it the whole procedure was relatively easy. The connectors a a bit tricky, but after a few tries new-old jolla work again. Now I have to install all the Sailfish updates since almost 2 years... step by step.
Well, not all. But, there are the mandatory top releases and even a factory reseted Aqua Fish takes about 1,8 GB of downloading to get it up to date.
A good range set of precision screwdrivers are a must for any kind of mobile phone tear-up job. I spent years keeping my iPhone 3Gs afloat with subpar replace touchscreens; couldn't have done without. And even with the right tools there still are questionable antenna solutions, tendrils and whatelse that take some damage in every teardown.

BT,DT. While removing and re-fitting the contacts is relatively straight forward, you need to be very careful with the contacts and everything. I managed to have a working phone after the surgery, but I sort of damaged the ear speaker.
@Edz's comment is very wise! Spare yourself the hassle of a mechanical teardown and reset the working device.
Thanks @Maus. I love tinkering myself, but it seems somewhat pointless to me to strip a phone that works. Personally, I would take a back up of my data while noting which OS the device is on, save the back up to SD card, then reset the device and update to the previous OS version, then put your data back on it - try for a day or 2, see how it feels - I can't see how a newer engine board will be any faster/slower than a slightly older engine board - it's not like a car engine with physical moving parts where things become worn - they either work or they don't. So yeah, spare the headache, reset, update, live your life. ;)
Spam Hunter ( 2018-01-27 12:52:43 +0200 )edit@Edz, I fully agree. But two phones may well be different in terms of flash storage writing speed. With growing age, all phones tend to be similarly slow, though. The flash component of J1 is rather simple compared to today's standards. There's no provisioning of fresh blocks, for example, which would speed up writing. Every single written byte means reading a whole block (typically 64kB), merging the change(s) in, clearing the block (zeroing) and re-writing it. (And this is even a very simplified description.) Fresh blocks don't need merging or zeroing, so writing those is much faster.

Have cleaned the contacts, but maybe this link is useful for you
