[Completed] Partitioning SD card on MTK device. Need a walkthrough. - XDA Assist

I have Micromax A104 with a custom rom [Sony Xperia E4]. No need to mention it's MTK based phone and has 2 partitions in the internal memory (~800MB for apps and ~1GB for files). So, I just searched a flashable zip to resize internal partitions on this ****ty phone and succeeded. Now I am having ~2GB space for apps and ~300MB for files. (I'm really not sure about numbers at the moment).
The first problem came was my phone saying "Damaged SD card, please format". It thought my internal SD card is corrupted. I played cool as it didn't bother me much and my apps were having a good time until today. I was searching for custom ROMs for my phone from a while but, wasn't able to find a ROM without less bugs, today I found one of Xperia E4. :laugh:
I installed it, everything's fine. Camera checks out, Synchronization checks out, and everything works fine. The only problem is, even though I have repartitioned my internal memory, I'm still having problem installing all my apps that were before. The ROM took much more space than the stock and now I've run out of space again.
I can't move app data to external SD card even with 3rd party apps like "System app remover" & "Link2SD". Please help guys.
I thought to partition my external SD card in order to keep apps on it, but I have no idea about which partition to make, file format to use, and what names I should give them.
TL;DR: Want to keep apps on external SD card, don't know partition format and afterward procedures to do so. Help
I have this 32GB class 10 Samsung EVO. I want to use 4GB of it to keep apps. Help me in doing so please.
Please note - My device is MTK based Micromax Canvas Fire 2 A104. I am using Sony Xperia E4 ROM (I don't think it matters). I have CWM recovery and I wasn't able to find a stable TWRP for it.
I would really appereciate your help. :good:
Thanks,

Why isn't my external SD showing up in file managers?

I can't find my external SD in Astro or Root Explorer, but the Android system shows it in the storage menu, and my camera saves the photos there, which I can see. I can also view it in recovery. Is there a reason my file managers can't see it?

It's most likely not formatted to the correct format then.

So why does the system recognize and use it?

Mine's the exact opposite. I have the Sandisk Ultra 64gb class 10. I can't see it in Recovery, but everything else sees it just fine.
Silly question, but are you looking in the right place?

you need to reformat it as fat32. There's a thread in the general section about it.

Verizon Galaxy Tab 7 Encryption Unsuccessful - Desperate!

I was using the AOSP ICS build posted by jt1134 (at rootzwiki dot com/topic/11697-rom-cdma-aosp-ics-cm9-build101-0418/) for the Galaxy Tab CDMA. The first couple of nightlies worked OK on the tablet, but the camera never worked right. Someone else insisted that the camera works correctly on new builds, so they suggested I use CWM to wipe system, and I took it to mean wipe everything so as to start from scratch, and I wiped /data too. Apparently this triggered the emmc erase bug or something, so now my internal SD is useless.
Nobody over in that thread appears to be willing to make a build that works around the issue. I've already tried partitioning my SD card and editing vold.fstab and updater.rc inside the ROM, but these are apparently useless unless init.rc in the boot image (zimage I guess) is changed. A person attempted that but seems to have gotten the filesystem type wrong in the build (ext2 instead of ext4), and is unwilling to make another attempt. I don't know anything about compiling a custom ROM myself. I've looked into decompressing/recompressing the zimage, but it's too much for me.
What I'm asking here is, can anyone help get a build of ICS to me that I can flash, that will ignore the internal SD and use the external? This site is awash with reports and fixes for Encryption Unsuccessful for other phones and tablets, so I'm hoping somene here can understand my frustration. I haven't been able to use the tablet for over a month now, I think, and I'm not getting anywhere on my own. TIA
Why not ask this great forums section for your device...

[Completed] How to extract [boot|cache|recovery|data|system].emmc.win.md5 from TWRP's NandBackup?

so i've just managed to search for a compatible TWRP Recovery for my Phone [Lenovo A7000-a (Plus)]
and as a basic move in making sure that your device wont completely die whenever you install a faulty rom or app or modifications, you make you first have a complete, or if not is a backup of the important partitions of your android device.
and so i did, since Lenovo A7000-a is powered by a 64-BIT MT6752, it is a little hard to dump it's rom.
i tried using MTK Droid Tool, but as many have told, it isn't updated or configured to work with 64-BIT Processors yet. so i'm left with a frozen window or if not, the phone won't connect at all.
i also tried using adb, but the system and the data partitions always return a bad image (something like the .img files of system and userdata wont be read by SPFT automatically which means there's something wrong with them). i also tried opening the images using ext4unpacker or ext2explore or same utilities, but it really is corrupted
i then tried using SPFT's readback utility, but the boot.img return a bad signature (which i also want to know why or how i can skip the boot.img)
so my last card was to do a Nandroid Backup using TWRP.
but i was surprised to see some xxxxxx.emmc.win.md5 files, which i have never ever seen yet.
so my question is, how can i extract the .img from these guys ?
as you can notice, the data partition has 3 parts, and the system partition has 2 parts
i want to know how i can extract the image files from these things so i can use them for SPFT ??
i hope somebody can help me out here. thank you
Note: The folder just says Lenovo_K3_Note, but the phone is actually Lenovo A7000-a [Plus]

I don't exactly remember how I solved this issue a few years back with my HTC WFS, but I do know that it was solved.
So I searched the internet and saw a video on YouTube about "External 2 internal"
I installed the app and while it prompted me for root, I accidentally tapped on the External to Internal button without setting the app as instructed. :crying:
This has resulted in restructuring of the entire storage space and I can't seem to fix any of that. All i remember was that it showed SDC as this:
But now it shows this:
I know that it has swapped the address, but IDK what the original one was to restore in the first place.
It has created these weird partitions and I can't seem to understand what's wrong with it.
I tried deleting the block folder in root/dev/ but it comes back after boot.
The files inside block are as follows:
I tried factory reset but no help.
Also, it has automatically removed all my linked apps. The link2sd now shows 2 partitions of the same storage space but after every reboot, the l2sd app disappears, and so does all those who get linked to SD.
Hi @sulayemaan. Since you messed up your partitions a factory reset won't help. You might have to flash the stock firmware again. There's no dedicated forum for your device here so try posting your query in:
