No way to use the UBPorts installer on a Nexus 4

[flohack]

@lool_lauris said in No way to use the UBPorts installer on a Nexus 4:

35M 4.1M 31M 12% /cache

I can see it already, cache is much too small: 35M 4.1M 31M 12% /cache - UBuntu Touch needs a cache partition of at least 500MB to install correctly.

Probably one of your alternative OSes has repartitioned the sd card. You could try to restore a factory image from Google, that should bring things again in order.

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.

@lool_lauris Never used any myself but there are plenty of tools on XDA Developers for nexus 4 just had a quick look. Google should have the stock rom for your device available somewhere if your not sure of the source of others.

Hi @lool_lauris
First of all use the stock image from the official website:

https://developers.google.com/android/images

I do not own a N4 but I do have a N5, I guess that it is the same procedure.

Download the latest build for your phone model.

Download Fastboot and ADB to your pc, I am linux user and have no experience with Windows or Mac.

Put your phone in fastboot, vol down and power button.

Connect your phone with usb cable, and make sure that it really works, there have been alot of wonky installs because of bad usb cables.

In terminal check if your pc detects the phone:

fastboot devices

On pc open Downloads.

Right click on”occam-lmy48t-factory-c43c7cfd.zip” and click on Extract here.

Open ”occam-lmy48t-factory-c43c7cfd” folder.

Right click the flash-all.sh script, click on Properties, under Permission tab, tick the checkbox for:
Make file executable
Close this window.

Right click on an empty spot in the folder, in the menu click ”Open terminal here” and run the flash-all.sh script. It resets the phone to default with partitions and all:

./flash-all.sh

It have been a while since I did this myself on my N5 so there might be a few missing steps like recovery mode. If there is such request press vol up or vol down on phone until it says Recovery, then press Power button to change to Recovery mode.

I guess you should be able to unbrick your N5 the same way. As long as your pc detects the phone.

And just what @Lakotaubp wrote earlier there are great tools over at XDA developers site to help you out too.

@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]

@lool_lauris Yes the partitions should be updated by the stock ROM, and even if not you cannot brick it, it wont just work as expected, in this case there are ways to repartition to the original layout

[lool_lauris]

@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.

[flohack]

Just an update: It seems that a factory flash does indeed NOT restore partition layout. So, you would have to google how to get the original partition table back on your device. Somehow /e/ or a different ROM seems to have messed with that automatically...

[lool_lauris]

@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...
