Misunderstanding about ubuntu touch on Nexus 7

taffymike · 29 Dec 2018, 09:31

I read at https://devices.ubuntu-touch.io/device/flo the one can have ubuntu touch on a nexus 7 but Lacotaubp wrote "*Each device needs porting individually you need to start here if you want to port yourself https://halium.org. As stated above your devices are not currently supported. Please also read this https://forums.ubports.com/topic/206/will-you-port-to-device-*x".
Is there a conflict between the info at https://devices.ubuntu-touch.io/device/flo and at https://forums.ubports.com/topic/206/will-you-port-to-device-x ?

@taffymike The problem is that there's more than one version of the Nexus7, but (IIRC) only one of them has a UT port.

taffymike · 29 Dec 2018, 09:51

@3arn0wl Thanks. My Nexus 7 is the Nexus 7 2013 WiFi I see that https://devices.ubuntu-touch.io/device/flo states Nexus 7 2013 WiFi (flo) and I do not yet understand what (flo) means. (More research needed taffymike).

@taffymike In your original post you said your model was 2012 hence my response. Only the one very specific wifi version works. If that is yours please have a go mine works very well.

@taffymike All Android devices are given a nickname for easier identification. The Nexus4 is Mako, my Nexus5 is Hammerhead, for example. Flo is the name of one of the Nexus7s.

@lakotaubp Thank you. You have pointed out my silly mistake. My Nexus 7 is indeed the 2012 model and I should have observed the physical differences when watching the video. So if I want to brick my N7 I'll go ahead and try to install ununtu touch. Errm, not a good idea. Pity, as I'm hugely appreciative of Ubuntu since starting to use it as my day to day OS on my PCs.

@taffymike Hi on a slight tangent. I would now like to close the flagged item you posted as everything has now been covered today in your new posts.

Nexus 7 2012 WAS supported years ago but NOT anymore.
Nexus 7 2013 Wifi-only (flo) is the one that's still supported until now in UBports.
Nexus 7 2013 cellular (deb) is I think also supported but I'm not exactly sure.

Mostly yes, minus installer support

Dear @doniks,

I'm considering buying "Nexus 7 2013 cellular (deb)" and as you pointed out in many threads i found, there are problems with installation. But I'm not sure, what informations are current and how to install it on the device.

Would you be please so kind to share some sum up of "what works and what doesn't" and "how to install Utouch manually" on the device ? You seem to know about the issue a lot. Thank you.

@zlamalp I might be wrong but I believe it is still only the Nexus 7, 2013 WiFi version that is supported. OTA-7 has a fix for that model that shipped with android 5.1 https://ubports.com/blog/1/post/192

zlamalp · 13 Jan 2019, 06:36

Hi @lakotaubp,

but I noticed there is a "Nexus 7 2013 (LTE)" item in ubports-installer (when you choose to select device manually). From various discussions I put together, that it should work if it's installed using some tricks. Older versions of nexus 7 are no longer supported by ubports (just old canonical image of 15.04 works).

I'd like to buy version with LTE and I can help with debugging if necessary to make it work. But if there isn't any plan to support this version, then I will rather go with WiFi only version of the tablet.

@zlamalp I'm really not sure then but until a definitive answer arrives here try asking in our welcome and install telegram group https://t.me/WelcomePlus

@zlamalp deb is on Ubports server, so I assume it should work. link text

zlamalp · 13 Jan 2019, 14:02

Hi @stefano,

I know its there, but there is also github issue related to this, that installation doesn't work an install different image (for wifi only version - flo), which fails to start or something like that.

https://github.com/ubports/ubuntu-touch/issues/643

Since @doniks participated in this discussions I kindly asked him for instructions. I don't feel like installing some twrp recovery or something like this, since I don't understand this much and I definatelly don't want to brick just bought device (even if second-hand).

And also from this github issue I'm nut sure, wheter "deb" is going to be kept between supported devices. Would be nice, if somebody from ubports could clarify it.

Thanks.

Stefano · 13 Jan 2019, 14:14

@zlamalp Yeah, that would be good if someone clarify that. I just bought Flo, 32 Gb, was tempted to get Deb, but it was more expensive, so I went for Flo. I had issues in the past to install UT on Flo, now it should be fixed, so I'm gonna try again.

Have a read of this it may help https://forums.ubports.com/topic/44/installing-ubuntu-on-nexus-7-2013-deb-lte Also use the forum search function to find other articles that may help

zlamalp · 13 Jan 2019, 18:29

Hi, @Lakotaubp, I'v read that. But it dates to 2016 and requires downloading some files from someones gdrive or knowledge of building own boot image etc. In the github issue linked by me is mentioned another approach (at least from my point of view). So I search for current status and installation guide. Also I want to know, if there is a goal to support LTE version.

Lakotaubp · 13 Jan 2019, 19:11

@zlamalp asked the question in the Telegram group so let's wait and see.

Hey @zlamalp , I haven't tried again lately, but I'm pretty sure the "deb situation" is still the same.

That means, the files necessary to install are on the server, however the installer somehow doesn't put them correctly onto the device. This means for installation you do need to break out the commandline and mess around. I don't think that there is a risk to permanently damage your device. At some point in between, yes you might run into a situation that it doesn't start anymore, but that is fixable.

With respect to what's not working

installer as mentioned, and I think this includes OTA updates. So, you might have to do some commandline dance anytime you want an uptodate version.
bluetooth doesn't work. I assume that this is fixable, but probably needs a recompiled kernel

Now, for actual cellular functionality ... I just cannot remember ... it's been so long that I haven't had a sim card for this thing. I actually assume that it works, because I think I would remember if it was broken ... but, again it's been years that I had a sim card inside. I actually wanted to reflash and try it, but I'm just not getting around to do it. I'm 95% sure it works. @zubozrout do you know?

Everything else, I'd say "just works"

With respect to continued support from ubports, that's always a tough question. Remember it's largely a volunteer run project. Resources are limited. That said, I don't see any reason why the support for deb should get worse.

Hth, doniks
