[Q] gellmar's StockMergE400 or SDMergE400 problem

Hi there,
I've flashed SDMergE400 and it has been working good on my L3 E400 CM9.
But if my externel SD card becomes malfuntional, i.e. the phone can't read the externel SD card, as the system data is saved there, will the phone not be able to boot up?
One more question: when I wipe data and dalvic cache, will it wipe out all my data and saved files in the external SD card?
Thx for any reply.

Re
Your external sd card is taken as the internal memory while the internal(actual internal) is merged with ur system rom , if ur sd card is malfunctioned ur phone will boot but the apps which are moved to ur sd card will not work properly, and if u clean ur data the sd card is untouched while ur system is cleaned ( which after installing sdmerge is system rom + internal sd )
Let me be clear now ur internal memory is ur actual external sd card and ur system memory is actual (system memory + internal memory) Hope i helped you if anything more u can ask and i will help you out

thx for the reply.
I'm just confused coz before I applied sdmerge, the internal memory was read as disc F while the external one as G when I connect the phone to PC. But after sdmerge, I hv only disc F which shows my external SD card contents while disc G has nth. The icon disc G is still there but the color is paler n it shows to insert disc G when I click on it.
Also I can see folders like 'Android' in the external SD card root. Isn't it a system folder? if yes, then why it appears there in the external card?
thx for reading n reply n I know that's a lot.

SDMergE doesn't do anything to your EXTERNAL card. It simply merges system memory and the INTERNAL memory into one.
There's nothing important in the Android folder on your external SDcard, probably just some app data you moved to the SDcard, nothing else. Check what's inside. If it's empty, just delete the folder.

Go to settings> storage and use the left soft key and then select usb mass storage rather than media device then u'll not get that greyed g drive....... and the android folder in ur external sd card has data of apps you moved

I hv flashed the 14July cm9 nightly and applied step 4 successfully.
However, I notice that whatever version I hv flashed, the cyanogenmod version in Setting-->About phone always show its 9-20130313-unofficial-e400. Is it becoz of sdmerge??

[Q] how to use app Data from External micro SD

I want to use app data from sd card (since internal memory is just 4.2 gb including application storage and data as well) what should i do, Am i suppose to do swapping ?? or some thing else?? kindly help..

I'm not sure what you mean, but if you're running low on internal storage, here's what I did for a fix:
First, apply one of the myriad of options for allowing any app to read/write the external SD.
Get the xinternalsd xposed module.
Tell it to make everything point to the external uSD card.
Then move everything from the internal emulated SD card to the external.
That will probably clear up a ton of space.
If you're still running low, clean up the app caches. If you really have 4GB of apps and data on internal storage, 1GB is probably caches.

Are you rooted? do you have a large SD Card which you do not swap out?
On my previous phone it only had 420MB of user space for apps. I created a 2GB EXT4 partition (could of been 32GB on my 64GB card if I wanted), then used Int2EXT system to move all the apps to the partition on the SD.

Apps2SD (on the Market) performs the same thing, with a front end

Features of Marshmallow - Episode 1 : Using microSD card as internal storage

New android version Marshmallow has a feature to use microSD card as internal storage.
When Marshmallow detects a microSD card for the first time it asks to chose Portable or Internal storage mode.
If you choose "Use as portable storage" you will use it as before. You can save your photos, videos, some applications or their data,
backup/restore your phone, etc. and you can see your files if you take it out of your phone and connect to another device or PC, as usual.
But if you choose "Use as internal storage" and click "ERASE&FORMAT" button at next screen,
then your microSD card will be formatted as ext4 and encrypted. You will loose everything in your microSD card and it will
become your only internal storage. Now, If you take it out of your phone and connect to another device or PC, it will not possible to see your files
since it is encrypted. Your microSD is usable only with your phone.
Than, what is the advantage of using microSD card as internal storage?
If your phone's real internal storage very small (ex: 4gb) and you have trouble installing new apps then you may put a 32 GB microSD card and use it as internal storage. Then your internal storage will be 32 GB (Not total of 36GB).
It will act as your phone's internal storage.
Disadvantages?
microSD card used as internal storage is useless out of your phone since it is encrypted. You can not use it taking out of your phone and putting into another device to transfer your photos, music files, zipped ROM files etc.
It will not be visible as external storage anymore.
Phone's real internal storage is not visible.
So,
If your phone's real internal storage is not too small and especially if you want to use your external storage as usual, there is no need to use a microSD card as internal storage.

But its still encrypted, so that won't help I guess. Also once you flash your phone or something, the contents won't be available anymore I think. It's just a guess though, I don't know how it is decrypted and all.

It seems to be not possible out of your phone by anyway since it is encrypted.
I don't not know whether it is possible to extract encryption key from phone and decrypt the files using this key but this shouldn't be possible because of security reasons.
No one desires access to the important files in the sd card if it is captured by any one else.

USB OTG Nougat

Is there anyway I can change the mount point of a USB otg to an external SD card or at least a partition that's accessible to certain apps like titanium backup and es file explorer on Nougat ROMs? I know its mounted as mnt/mediarw/... / but it's only useful for transferring files from and to the USB and doesn't allow apps to access it which I need for storing and restoring apps/data for or from titanium since I don't have much space on the 32gb g2 anymore. Most of the time I only have about 2 or 3gb of space left which isn't enough for nandroid backups(5-9gb of space) and I end up saving it on the sd card anyway but I have to restore it to the device storage if I want to restore apps or data from it.

What are these files in TWRP?

Are these files safe to delete? I was under the impression that with this being a 16gb phone I wouldn't be fighting for internal storage space after owning the phone just a few days and less than 10 installed apps.

Looks like your own backups... your internal storage wouldn't be full if you bothered to use a sd card.

If one does have an external SD card, I don't recall if TWRP defaults to storing there or if you need to select external SD - something to check on for TWRP newbies.

I've found TWRP to usually default to internal storage on every run, but once you set up the path/naming for your backups it usually sticks.
It seems like you are toying around with TWRP, possibly attempting to get ready to flash a custom rom. Given half the storage is system files, you'd barely be able to backup said default files to internal storage without running out of space.
You could always backup these files to a computer, delete them from the phone to free up enough space to download a rom (of which you should verify the md5 checksum), and hope everything goes perfectly.
If anything goes wrong, you'll need access to a computer and either use some advanced fastboot commands or.. an sd card, which you can easily swap on to a computer to download custom roms or backup files.

I would recommend getting a micro SD card for TWRP backups to avoid being fully dependent on a PC or internal storage. I like to have at least two TWRP backups on my micro SD. I know this phone works with 128GB - not sure about larger.
