Bq E4.5 upgrade to UBports safety and rollback possibilities
-
@jumpy88 Hi. I bought the E4.5 ubuntu edition in 2015 as my first smartphone but by 2017 I had put it away in a drawer! I found it too unreliable, I was missing calls and this was my only phone. In 2018 I took it out again and flashed it to android following instructions on the BQ website at that time; I wanted to help my daughter whose phone had broken. As it turned out she didn't need it!
Anyway, this was when I discovered ubports. I used the installer to get ubuntu touch on the phone and haven't looked back. It was great then and it's even better now - you are going to really like it! If you have any problems there is all the support you could possibly need in the fantastic ubports community to help you.
Good luck and enjoy!

Ok, you all have convinced me
Copied my home with a mere cp -r /home/phablet <microSD card>, removed the microSD card and checked I can read my SMS and call events data (found they are in /home/phablet/.local/share/history-service/history.sqlite which can be read with https://sqlitebrowser.org if someone arriving here needs it).
I'm ready to start, just the time for reading https://docs.ubports.com/en/latest/userguide/install.html -
@jumpy88 Good Luck! But it should really work out fine, we did not change so much from Canonical times, but one thing: You will find an assistant that will upgrade all apps from 15.04 to 16.04 if there was a new App published for that.
Between releases Apps might break, so unfortunately a few apps do not have any maintainer anymore and therefore were discontinued. I hope you dont use many of those
-
Done!!! I'm on board from about 45 minutes. Don't worry about the apps. Because the last version by Canonical was few steps away from beta release, I actually used it just for calls, SMSs and as an access point.
Now the bad news: I can't connect in USB tethering mode. With the previous version I could run$android-gadget-service enable rndisand the phone appeared in my desktop Ubuntu as an ethernet cable connection. Now the command does something, my computer starts trying to connect but actually never connects (it seems as if the computer didn't find an active DHCP assigning an IP to it). Is this a known problem someone can give a quick answer here or do I begin a new topic? In the second case which is the right category for this kind of issues?
-
@jumpy88 very basic question sorry but have you checked developer mode is on first. Lets solve this one while your here to get you going. Anything else relating to a specific issue goes in Support. Have a look at the categories there pretty self explanatory. Oh and welcome to UBports.
-
@Lakotaubp I've tried both with developer mode on and off, but the behaviour is the same. Anyway with the old version it worked with developer mode disabled. Let me know if I've to create a new topic. And thank you for the welcome
-
@jumpy88 I'm done for tonight sorry. Early start tomorrow. Lets leave the question here for now as I said and get it sorted. Someone maybe along to help soon things are always a bit slow on Sunday. Good luck will check how things are in the morning.
-
@Lakotaubp ok, I'll wait here someone who knows something about this

@jumpy88 said in Bq E4.5 upgrade to UBports safety and rollback possibilities:

I'm ready to start, just the time for reading https://docs.ubports.com/en/latest/userguide/install.htmlIf you are used to use (heavy) the MUA Dekko, be prepared to use Dekko2 in the future. For the transition, have your SMTP, IMAP and other credentials handy (because there's no automated update). For the rest of the difference between Dekko against Dekko2, advantages and problems search the forum.
-
@guru no, I didn't use it, but I will take a look in that when Dekko2 will be ready
About USB tethering? No one has quick advice to make it work? -
@jumpy88 can you check the steps here http://docs.ubports.com/en/latest/userguide/advanceduse/reverse-tethering.html? Maybe it could give you some additional idea (?)
-
Thank you @advocatux, I've tried to follow that guide:
- enabled developer mode
- enabled rndis (with explicit notification on the terminal)
- connected USB cable
The problem is that the computer doesn't get an IP from my phone, so I'm stuck at step 2 of the guide. Moreover, I don't remember if it should, but running ifconfig on the E4.5 terminal there is no interface that seems to deal with rndis and usb connection. Can someone with the same device check if it is possible to enable USB tethering and, if it works, check if enabling rndis makes it appear a new interface? (Check also if it is visible before to connect it to the computer).
Anyway, if we don't solve in a couple of posts I think I will create a dedicated topic, because we are very OT. -
@jumpy88 I think that as nothing has been fixed by now it is probably best to create a new thread. Unless of course an answer has appeared before you read this.
-
@jumpy88 This is new territory for me but following the user guide in the docs I did this...
On E4.5 I enabled developer mode
connected to pc via usb
open terminal on phone and run command to enable rndis which returned confirmation rndis enabled.On pc I ran the command at Step 2 in the docs
This returned an IP address and a lot of numbers and I'm not too sure about going much further at the moment!
I would be happy to try to take this further later today, but as Lakotaubp says, it would probably be best to continue in a new thread, in the Support category.
-
@ziggutas be sure you don't have other active connections than USB connection with your phone (ethernet cable, wifi, other USB modem...), otherwise hostname command may return informations about that.
@Lakotaubp I agree, I'm going to create a new thread -
If someone here is interested, the solution is there.
