[Q] Application/Data partition resize?

Hi.
I've rooted my A70s with chulri's kernel and it seems to work ok.
My next goal is to get more app room ... so I guess I need to resize the app/data partition.
I've thought that having my internal storage formatted on ext4, it would be possible to ln the /data folder to /storage/data without problems, but then I should create a boot script for that. The question is... can I do this with my current root status? What would be the way to do it? I'm don't know enough of linux os to make it on my own.
If the system can't be fooled with a ln, then is there any way to resize the data partition, even if I have to backup/restore my current data?
I don't want to use Urukdroid, since all the versions I tried were very unstable on my machine.
Cheers!!

Follow chulri's method, or repartition your internal storage in Linux, mount it on the archos, and copy the data there. Then edit init.rc and change the data mount line. If it gets mounted in the kernel, you'll have to umount it first to remount it to the other partition.

[Q] Mounting dd partitions

Hi guys
Using ADB copied all the individual partitions (boot, aboot, system, recovery, etc) from my device to my sd card and then to my pc (Linux). Device is a Hisense Infinity H6 (HS-U800).
I am unable to mount any of the files, and have tried gdisk, fdisk, mount. I get a mount error or wring filesystem type.
Also trying to dd the entire block directly makes a single image that i am unable to read. I tried using gdisk to repair the gpt or recreate an mbr but to no avail.
I would prefer to work with the individual partitions as it appears that they have different filesystems for each. But when I specify the filesystem using mount i get a wring filesystem error.
Would appreciate any help, thanks.
PS
I'm using Ubuntu 14.04 LTS.

Never mind, it turns out that if you dd directly from phone memory to pc android corrupts the files. Fixed it by using the sdcard as an intermediary step.

Mounting boot partition

I have a Moto X 2013(ghost) and want to mount my boot partition out of curiosity. Either on my phone or my PC. I pulled an image of the partition with dd but I can't seem to determine the type of filesystem in the partition. The file command just labels it as data. Can anyone shed some light on whether or not that partition has a filesystem at all? I'd imagine it would have to then again it wouldn't surprise me if it didn't.

/data (mmcblk0p8) filesystem format on KatKiss v30

Hello all,
I'm hoping someone can help me with this. Long story short, I've bricked my Prime. I was running TWRP recovery (AndroWook, so 2.6.something?) and KatKiss v30 when things went south... but unbricking is for another day.
I'm more interested in getting some data that didn't make it into my last backup off the /sdcard. I don't have access to the device itself (adb or fastboot, haven't tried APX yet), but I did managed to take an image of /dev/block/mmcblk0p8 via the dd command.
The problem is I can't mount it as a loop device in Linux. The problem that started all this was that KatKiss wouldn't boot... the output of "fdisk -l /dev/block/mmcblk0" suggested that its partition table was corrupted or gone.
Various suggestions on XDA and elsewhere (xmount, kpartx, etc.) haven't allowed me to mount this backup image... I'm wondering if the missing partition table isn't the issue.
[email protected]:~/prime_backup_microsdcard_32G_20151227$ sudo mount -t auto -o
loop tf201-mmcblk0p8.img /mnt
NTFS signature is missing.
Failed to mount '/dev/loop3': Invalid argument
The device '/dev/loop3' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
So my thought is to try the following:
1. Create a virtual HD of >27.GB (the size of the backup image).
2. Create a partition of the exact size/dimensions as the backup I have, and ensure I'm able to mount it.
3. Restore the backup to this partition using dd.
4. Profit.
Does this make sense, and if so, what format is /dev/block/mmcblk0p8? Based on the steps to install KatKiss I would have guessed f2fs, but the mount error above makes me think otherwise.
Thanks in advance for your help.

Mounting 2nd partition (ext4) of externalSdCard

Hello everyone
I am having trouble mounting second partition of my external sdcard. I’ve already done as much research as i could but i couldn’t find the answer.
I am using busybox to try to mount /dev/block/mmcbl1p2 to any folder (tried in /mnt; /storage; /mnt/media_rw; and many more) but my mount command says invalid argument.
To explain what i did, in short i have a raspberry pi, i used piped unzip to dd command to write the raspbian image on my sdcard. dd command was successful and raspberry pi can boot from it. What i am trying to is setup my raspberry headless by editing /etc/network/interfaces which is located in second (ext4) partition of my extSdCard.
I know android understands linux file systems but i also know it only mounts first vfat od sdcard. Is there any way to access the files from second partition of my extSdCard ?
I am not sure how to find the answer since everything on google is related to moving apps to sdcard
Thanks
Device: Huawei Y5II - CUN-L01
Stock rom
I managed to set it up headless by using UsbTethering and connect to ssh through that connection since dhcp is auto enabled on this image for raspberry, but i would still like to know how to mount this partition. Thank you
