Root Proposal/Theory for External SD storage solution on F6

irWM1qA.jpg


Got it working perfectly. installer is coming. Sorry for the wait guys.
 
pressy4pie.
Will this be released soon? I would like a copy if possible. I have a 32gb card and would like a 4gb app storage if possible.
thanks.
 
Lol this thread is like the Bermuda triangle. Everyone who works on it disappears

I have been running what he sent to me without issues since I posted the picture of my storage above. I have not heard from him since the night he sent me the files for testing. What he sent me is not packaged and I don't think it would be appropriate for me to post someone else's beta work here without their permission.

Pressy4Pie may be busy. I know he was trying to make this memory fix and recovery to play nice together. He mentioned trying to get twrp on the f6. Give him a little more time. If it looks like he went the way of JVene then we will figure something out.

yea im in and out. and i have no eta. i work on it in my free time. im dicking around on it right now, but like i said, its only in free time and ive had a bit of other stuff to worry about.
 
I wish pressy4pie or someone could help me figure out how to take the current mem mod by androidguy1991 and figure out how to keep the settings to not reset on reboot. If I could figure this out, I'd be happy with my internal memory situation.

Although pressy4pie has the beta out and it is cool and he has worked hard and long on it from what I've seen on this forum. Not only this mod/hack, but several other ideas and support help to others. Great work pressy4pie!!

I am still not sure if pressy4pie mem hack is one that just swaps/duplicate SD card or if it is real added gb to the internal storage. Is 4GB the most internal storage we can get?

As of right now I use androidguy1991 mem mod and that alone. I have basically 29gb of merged mem. (duplicate/not swapped/or kinda is) I have like 5-6 two gigabyte games installed, numerous apps ranging from 1mb to 1gb+, movie, music and pic's ect. My problem is rebooting or losing charge, basically if my phone dies or I have to reboot I have to manually unmount SD card, then mount it back (not remove, just in storage settings) in order to get it back right.

What I'm asking is, how to reboot and it stay the way I want it? I have screenshots of my storage showing 29gb+ internal and external, the way I want it all the time, and 29gb+ internal and 1.27gb external, the way it looks after reboot.

Thanks for any help and much appreciated ahead of time. ;-)

i am not entirely sure what you are talking about, but check my post on the metro root forum. i just released my mod but i dont know if thats what your asking for lol
 
Will I get more than 4gb of internal storage? Tomorrow when I have time I will upload a video or screens and try and detail out what I mean a little more. Your mod sounds good, but what I'm doing has been working great and gives me basically 29+gb of "internal storage" and I get no insufficient storage errors.

Did you try using a smanager script on boot to do it automatically? I mean that's how the app to external SD mod works I don't ever have to do anything I just restart my phone smanager does it for me.

[MOD] [Beta] SdCard Memory Hack

The advantage of this is it maps the sdcard second partition as internal memory. Much better than the other memory solutions on this forum imho
 
great work. where to look on irc? just got this thing not realizing this issue. super impressed by the speeds though, but I probably want to fix this before I ad one ebook and destroy my phone
 
This discussion is a little over my head. I keep seeing "Link2SD" popping up. Does this revolve around getting the phone to install apps on the Ext SD by default? My HUAWEI Premia had an option under storage to allow the phone to use Ext SD. This phone does not.

EDIT: Does Titanium Backup provide the same features as Link2SD? [Or, Lucky Patcher for that matter]

EDIT2: I have installed some apps. In each case, when viewing app info, the "Move to SD Card" option is greyed out. Is this because the app was installed directly on Ext SD? Or, some other issue?
 
I've read a few threads in several forums here over the last few years...typically, trying to figure out what one of my kids/step-kids did to the kindle or one of the phones.

A week ago I got 3 f6's (refurbs) and ported 3 lines from verizon. Cut my bill from 230 to 105 after the taxman. ...had to send in my old phones though, hence, the f6.

atta glance, looks ok, cheap, great battery, decent cam, etc... ordered 3... gottem... activate... "this memory sucks butt"... wallowed in self pity for a couple workdays, longing to have my gzone c811 back... decided on research... rooted mine 1st attempt, (great tutorials to b thanked)...

Then last night I was destined for the couch. Went out to the shop for a cig and ran across this thread... I read straight through, in entirety, much of it twice. Like Tolkien when I was a tween, I "couldn't put it down". The problems, the unlikely heros, the joining of forces, the distractions, failures, promises... Like prisoners exiled and waiting for a their stay of execution... hopeful at first, overjoyed even, then purposely positive, then doubts edging to the front, finally, action driven by desperation and the realization that if not I, then who? if not now, when?

Well enough drama! Great read though. I slept fitfully this morning from bout 5-7 and dreamt I was 9 again, writing music programs with my TRS-80 and a cassette recorder for a disk drive...I had forgotten about that!

Anyone have any updates to their successes/failures/theories?

And has anyone checked obituaries for jvene??? ... Maybe google went gangster on him! I'm sure "there's an (top-secret) app for that"
 
I want to thank JVene for his work and confirm that I implemented this successfully. JVene's posts are informative, but long-winded, so here is a TL;DR for people that want to try this. I'm assuming you vaguely know what you're doing (comfortable with linux command line), so I'm not going into extreme detail. Read all the steps first and if it doesn't make sense, I wouldn't recommend trying it as you could mess something up.

1. Partition and format an SD card with a Fat32 partition (1st) and an Ext4 partition (2nd). Choose your size for each. Fat32 will be your new "sd card" and Ext4 will be your new "internal storage".

2. Download and extract the app_process binary that JVene attached to one of his posts.

3. Mount /system read-only ("mount -o remount,rw /system", you need root). Rename your original /system/bin/app_process to something else for backup. Copy JVene's app_process to /system/bin/app_process.

4. Create /system/etc/init.d/zinit.sh (in a nutshell, JVene's modified app_process runs this script before Android initializes) and chmod 755 zinit.sh.

5. Insert "#!/system/bin/sh" as the first line in zinit.sh, then insert your boot-time commands below it. You have several options for your commands, what I personally did was mount the ext4 partition at a temp mount point, copy /data to it, then mount it at /data. This will copy /data to the ext4 partition of the sd card while keeping your original /data partition intact. You can also enable USB debugging beforehand and enter sleep x as your command where x is the number of seconds you want the device suspended prior to loading Android. This will give you time to connect with ADB and manually perform file operations. You could also just mount the new partition at /data and start with a clean slate. The ext4 partition on the sd card is /dev/block/mmcblk1p2, so to mount it at /data: "mount -o rw -t ext4 /dev/block/mmcblk1p2 /data".

6. zinit.sh will be executed during each boot. If you added commands to temporarily mount your sd card partition and copy your current data partition to it, remember to remove them after the first reboot. Your first reboot will also take a fair amount of time at the boot screen as your /data partition is copied. The only command that stays in your zinit.sh file after the first boot is the mount command (unless you want to do more).
 
I haven't been here for a while and the last time I was here, I believe he said he will post the code and etc after his testing in his son's LG F6. So, from what I understand from couple of past posts, others are confirming that what he wrote is working!

So can someone recap what have gone by while I was absent? Will the SD card replace the partition or just another way of performing "link2SD". I see you have to create two partitions but what is the reason for it?

In Link2SD, it just installs the apps and its data on the primary storage first and links it to the secondary "hidden" partition within the SD card. So theoretically, your space can run out in this kind of configuration. Any difference between link2SD and what you guys have done to your LG f6?

Thanks!

I'm not sure if JVene released the full source, but there isn't much to the app_process source to begin with. All he did was add a check for /system/etc/init.d/zinit.sh and execute it if it exists. There isn't much chance for breaking anything and I haven't had any issues myself.

The ext4 partition on the SD card, rather than the internal flash memory, gets mounted at /data. This means your small internal partition is still there, with whatever data was on it, but isn't being used. You could technically mount this somewhere and utilize the space, but it isn't really worth bothering with. Once this mod is done, you don't have to do any linking. The phone behaves as if it has as much internal memory as you made the size of your ext4 partition. Apps get installed on the SD card automatically, because Android thinks it's internal memory. I didn't experiment with leaving out the Fat32 partition myself, but my understanding is that the phone expects the first partition on the SD card to be Fat32 and mounts it as external storage. It doesn't have to be very big if you'd rather allocate more storage to "internal storage", but I've read that others have had problems or error messages if they leave out the Fat32 partition.
 
This would make this phone 1000%. To me the storage on this phone is it's only downfall. I only wish that it could be done by a layman like myself. I can do somethings, but am not as computer literate as it appears one must be for this.
I have done the xperion rom and I have the link2sd on my phone, Using Aparted. I know that this is eventually gonna run me out of space. it works for the time being. but would love a permanent solution to the storage problem that all F6 users have.
Not sure how to do what you are showing, unfortunately for most users.
