[Q] Understanding partitions' layout topic

I have some difficulties understanding partitions' layout of my phone. (Huawei G6-U10 ***NOT*** rooted yet)
As spec:

4 GB Internal Memory
|__ 2 GB reserved

|__ 2 GB Internal Storage

|__ Memory android option menu shows ~2 GB total (1,91 GB) but only ~1 GB (1,03 GB) available.

If I connect my phone through MTP it shows as internal memory just a partition of ~ 1 GB (994 MB)

32 GB external SD

Code:

Then I listed partition symlink by name

Code:

Assuming a blocksize of 1024, I can see that sizes of mmcblk0p23 (/system) and mmcblk0p24 (/userdata) are 1 GB each.


1) The space unavailable from internal storage, is the /userdata partition?

2) Of the 2 GB Android doesn't show at all, 1 is obviously occupied by /system, but if the sum of all the other partitions on the first block device (except /userdata and /system) is equal to ~1,67 GB, how can it resides on the 1 GB remaining space?

3)What's the /grow mountpoint?

[Q] Partitions corrupt on internal memory topic

Hi,

I have a rooted Galaxy S3 I9300. One fine day, it just died on me, and is now perennially stuck on the Samsung logo.

I have CWM recovery installed, and I can boot into the recovery and the download mode just fine. However, in the recovery, I see that I am not able to mount even a single partition, including data, system etc. So flashing a new ROM etc. is out of the question. Also, I have tried flashing ROM's and PIT files using ODIN, and each time I get a big red FAIL message.

Also, using adb, I am unable to manually mount any partition, giving me the error message that there is no such file and directory.

At this point, I know people will say that my eMMC is fried, but here is the thing - I can access whatever files are there on the memory using adb. It's just mounting that is the problem. Can anyone suggest what the solution to this problem can be?

[Q] Aroma installers freeze on formatting partitions topic

I'm having problem installing ROMs with Aroma installer (it was working earlier and I missed the point when the things gone wrong). It just hangs on 'formatting partitions'. I've experienced this problem with to different ROMs: Android Revolution HD 90 and stock ROM from htc1guru.com
Manual formatting from recovery and backup restoration works just fine. Any ideas?

Thanks in advance!

Stuck on HTC Logo at Boot + Possibly missing partitions topic

With all the buzz about Android 5.0 lately I hastily decided to flash across the latest and greatest. So of course it turned out I needed S-Off for something (because it never gets to be easy) so after running various hacks in an attempt to get S-Off I noticed that I couldn't boot into Android. So I opened up the recovery and tried to sideload across a stock HTC KitKat ROM. When I turned on the sideloading function I got the following error: "failed to open driver control: No such file or directory". And this wasn't the first or last error that I would get. for example, if I tried to access my /sdcard partition I would receive the error message: "E: Can't mount /sdcard". To me this seems like either my partitions have been deleted or corrupted.
Other directories I also cannot mount are:

• /data


• /firmware/radio


• /firmware/adsp


• /firmware/wcnss


• /sd-ext

Note: I am running PhilZ touch as my recovery.
