Issues to explore mobile filesystem

Postby cronomorfo » 2020-01-29 17:44

Hello,

I'm trying to explore the contents of my Huawei mobile phone and while Debian recognizes some sort of partition dedicated to install a Windows app associated with that given model, the OS fails to mount the filesystem.

I'm running Debian Buster, and my mobile phone is a Huawei Mate 9 lite.

After plugging the phone through a USB cable, and answering the prompt raised by the phone that allows exploring data through USB to a computer, Debian raises an error that, in English, should roughly be translated as "Failed to mount the filesystem: the device doesn't respond".

Please bear with me, I'm not very adept at looking under the hood in Linux systems, I've been more of a Windows person for years until... yesteryear?

Using lsusb, I can see that the computer recognizes the device:
Code: Select all
ayin@nua:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 024: ID 13d3:3487 IMC Networks
Bus 001 Device 003: ID 0bda:57ed Realtek Semiconductor Corp.
Bus 001 Device 018: ID 0c45:7692 Microdia
Bus 001 Device 017: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 015: ID 05e3:0608 Genesys Logic, Inc. Hub
Bus 001 Device 036: ID 12d1:107e Huawei Technologies Co., Ltd.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


The info obtained through lsblk, however, shows that OS doesn't list it as a block device (which I understand would allow me to mount it manually)... but it lists something in the Huawei devide as "rom", which is the Windows app included.

ayin@nua:~$ lsblk

Here are the dmesg log related to the Huawei device. I thought that you might be interested in seeing it, but I don't have enough experience on the system to see if anything here is indicative of the issue.

Can anybody give me a hand? I'd appreciate it. I'd even appreciate at least having a sentence or something that helps me define the issue so I can Google my way in.

1 - You first need to be sure usb data transfer is active on your mobile (a menu somewhere in android / I use lineageOS)
2 - the protocol used to access the mobile memory should be mtp (multimedia protocol).
3 - check that you have some mtp protocol libs installed
Code: Select all
apt list --installed '*mtp*'
libmtp9 for example.

Hi!

1.- I'm aware of this sort of issues. My phone model prompts me to confirm whether USB data transfer is to be enabled each time I plug it to a computer. And I can do it correctly on other computers, so this doesn't seem to be the issue.
2.- Confirmed. I've been trying through MTP.
3.- It seems that this is not the issue either:

Code: Select all
ayin@nua:~$ apt list --installed '*mtp*'
Listando... Hecho
libkpimsmtp5abi1/stable,now 18.08.3-1 amd64 [instalado, automático]
libmtp-common/stable,now 1.1.16-2 all [instalado, automático]

This is the data generated after plugging in the phone but before providing access to device data (as per mobile UI prompt).

Re: Issues to explore mobile filesystem

Your udev seems to correctly detect your phone.
Can you be 100% sure usb data access (mtp ) is active on your phone ? On mine I need to activate it.
You say yours is "automatic", but ... you can't access your data.... then verify.

I don't use same mtp libs as yours (libmtp9), but never had any issue in KDE with my mobile.

Re: Issues to explore mobile filesystem

Postby cronomorfo » 2020-01-31 10:25

I've never had any issues with the phone when I was using Windows. Once I jumped to Debian I just couldn't access the filesystem though MTP with that machine. I still can connect it to my partner's Windows computer and do whatever I need to do, so I don't think this has to do with the phone.

I understand that it actually detects stuff in there. As I mentioned, I can interact with some stuff in the phone, mainly the things that are stuffed in that "My_CDROM" space (partition? I don't know what it is) where it's located the recommended app to manage the phone on Windows (never used it, though, it worked just fine as any other phone connected through USB). I think I can access photos through the access method that's oriented to work on the phone as a camera.

It's just weird.

Like additional drivers and a pdf manual in/on that CD image?
bingo, it is in your phone settings. I can't say exactly but I had a phone like that and there was an additional mode setting on the phone for it to appear as storage, ie internal plus SD, OR, that's OR emulate a CD rom. I tried to make that emulation serve up a bootable image and the largest image size possible was like 50MB or something. Point is, since you are seeing the CDROM, you dig deeper into the phone settings.
Another question would be, does windows NOT show the CDROM, or does it show 3 devices, CDROM, Internal, External SD? if windows does not show the CDROM, I have to ask what are you changing as you walk over to the windows machine after debian said it was a CDROM.

My example was either or. I eventually did get it to show 2 CDROMS, with images from the SD, and yes it would boot a computer, and no I couldn't see the standard MTP storage in that mode.

I do think camera mode gives access to the default camera storage only.

Android offers to be able to show the phone over USB in multiple ways. One such way is a virtual CD-ROM. Some manufacturer's devices use this virtual cd-rom device to supply their own tethering software.

However, you can, with relative easy access any phone wirelessly using ftp. Since many clients software, most file managers and browsers can browse ftp, this is makes it - I would argue - much easier and convenient than going over USB. And transfer speeds in LAN are pretty good nowadays. I mean, you don't even need a cable... you can even send the files over the internet if you connect over VPN.

I think you're right. It seems to me that it's something in the phone's settings. Even though I've been messing around with the USB connection settings, nothing has worked.

In Windows machines, I usually can see right away a MyCDRom drive, and the phone produces a prompt asking for authorization for data transfer and afterwards the sort of data being transfered: MTP, Camera or MIDI data. After making a choice, Windows announces a new drive, which can be accessed as expected.

In Debian the phone does the same routine, but Debian detects right away that you can get into the phone through two different ways (MTP or Camera) and a CDROM unit has been inserted. The CD can be accessed as expected, and in Camera you can remove files (but not add them, as it appears to be a regular limitation of the method). If you try to go to MTP, Debian answers that the filesystem couldn't be built. If I go back one level and try to get again, Debian sees the folders but can't actually open them. Only certain segments (the Downloads folder, for example) can be accessed and manipulated, but not all.

I guess this has to do with finicky settings in Huawei's implementation of Android. As I'm tired of struggling with this, I'll probably try loading a Win VM and do my business with my phone over there. It's not ideal, but it's something. Otherwise, i'll be just Bluetooth transfers.

Thanks for your help.

How would that work?
