@flohack
Thank you for this clarification; that's what I was presenting. I've already done quite a bit of research concerning a return to the original partitions. I also have this problem with a Nexus 5 that I've been trying to bring back to life for quite some time now...

@flohack
Many thanks for your reply.

I put the problem on hold for now. Indeed, I lent the phone that is under /e/ to someone who needed it.
Thank you all for your interventions.

@rondarius and all
Thank you all for your messages.

I must point out that I am also a confirmed Linux user and that I've been using ADB (and fastboot) for quite a while now. I'm sure, however, that I still have a lot to learn (the more I know, the more I can measure the extent of my ignorance).

I know these manips pretty well (those described in the Rondarius's post) because I've already practiced them quite a few times. And thanks for the link to the official stock Rom; I compared the checksum with what I've already downloaded and they are identical. But, you're right, you should always retrieve the data from the sources without going through an intermediary.

But my question is not about the procedure to be applied to flash the phone. What worries me is that apparently the partitioning of this Nexus 4 has been modified; and I fear possible problems when flashing the official rom stock without having made certain prior arrangements. I had a bad experience with a Nexus 5 that is currently bricked (I'm not desperate to bring it back to life...).

Do you think that flashing the google Rom will restore the original partitioning?

@flohack
Thank you for your help Flohack.
And do you think that flashing a stock ROM will resize the cache?
I found this => https://androidmtk.com/download-google-nexus-stock-rom-models
Would you know which firmware to choose between 4.4.2 (JDQ39) ... 5.1.1 (LMY48T) ?

I'm a bit suspicious, I had a bad experience with a Nexus 5 on which I had installed several OSes (including UT) and when I handed over an official stock ROM, the phone became a brick.

Yes, I saw that, but what should we do?
As I explained, on this phone after trying unsuccessfully to install UT, I installed a TRWP recovery and the rom /e/ and this without any problem, so there is space to install it.
Why can't the installer manage to take the space that exists?

Hi,

I'm desperately trying to install UT on a Nexus 4 but the installation doesn't succeed, see this post => https://github.com/ubports/ubports-installer/issues/1716
At the end of the failed installation, I stay stuck on the recovery screen.

In November 2019, I also had problems installing via the UBPorts installer. I had managed to get out of it by going through a manual installation => https://forums.ubports.com/topic/3340/solved-nexus-4-impossible-to-install-ut-via-the-ubports-installer-tool/3
At this time it was possible, the images were made available. It's a pity that this manual installation is no longer possible!

I specify that the phone is not bricked, since I installed a TRWP recovery and /e/.

Nice you succeed to install UT !
It seems that you did not follow this => https://forum.xda-developers.com/google-nexus-5/orig-development/repartition-nexus-5-repartition-t3844395 ... how did you proceed ?

After flashing "twrp-3.3.1-HH-hammerhead.img", through the TWRP terminal did you first resize :

hh_repart -m

Reboot and then, still through the TWRP terminal :

hh_repart -r

Hi,

I had a similar trouble as yours : unable to install UT => https://github.com/ubports/ubports-installer/issues/1070
In fact, I previously installed an unofficial rom of LineageOS => https://forum.xda-developers.com/google-nexus-5/orig-development/rom-lineageos-16-0-nexus-5-t3921162
To do it, I needed to resize the partition => https://forum.xda-developers.com/showpost.php?p=79928889&postcount=190
So, I have done a revert partitionning and everything went well, I was able to install UT.

@AlainW94 said in Backup and restore using ubports-installer:

@lool_lauris Only working with UbPorts phones, I tried it with a Meizu Pro5 on Android and it's not working.

When I was asking about any phone, I was meaning the available phones for UT, of course.

HI,
An this backup option will accept any phone in its factory setting ?

Everything except google !
Seriously, it is a good idea. I will try to find a thing in that way. Thank you.

@doniks said in Libreoffice and Firefox.:

Going a bit off topic herexlsut can you use a simpler technical solution? like editing a text file with the ... five ? or so numbers you actually have to modify? does it have to be xls?

Thanks for your answer.
In fact, it is a spreadsheet with equations. It is therefore an .xls file but can just as easily be an.ods file. However, I need the formulas....

@AppLee said in Libreoffice and Firefox.:

@lool_lauris You can connect a bluetooth keyboard (+ mouse).

OK but I have to modify the .xls file when I am preparing a glider on the airfield runway. So I have only the phone and not keyboard...

In fact, I am looking for an app to open and modify a .xls file. I did not find anything to do that... This is the reason why I tried LibreOffice. And it is obviously not usable.

By my side, I have installed LibreOffice through Libertine in a Nexus 4. It works. But the problem is that there is no keyboard to enter any entries...

Hi,
I also had a problem to install UT on a Nexus 4.
The best for you :

• Reboot the phone by holding simultaneously the Power button and Volume down button.
• You should have the Android boot screen with the indication START at the top.
• Hold the Volume (down or up) button to find the Recovery mode. When you find it, hold the Power button.
• On the computer use the UBports installer, connect the phone to usb port then follow the indications given by the installer.

@HendriXXX :
In your 6th video, you are showing installation of Anbox. You use an image dedicated to Nexus 5 (hammerhead).
By my side, I'm using a Nexus 4 (mako). I didn't find any image for this device. Do you know a way to install Anbox on Nexus 4 ?

Using UT, so using Peertube => https://joinpeertube.org/en_US/
