Lagfix + data2sd (Quadrant score 570 + Lot of space for apps)

I am working on custom ROM with sdcard lagfix and disregard this thread. Please wait for some time. Will give you good news soon...
Imagine having 1GB space for apps and superfast phone.

Note: You should have 2 partitions in sdcard to apply this lagfix. First partition should be FAT and second partition size should be over 1GB. Attached format sdcard document have instructions for this.
Currently /data in our phones is on rfs file system which is making phone slower and you can not install apps size more that 150MB. This Lagfix will make ext2 partition in sdcard and use it for /data. ext2 file system is faster than rfs which will make phone faster and give more space for apps as ext2 is in sdcard.
. Attached 2 Lagfix versions. Filename with 1GB will have 1GB space for apps and sdcard need to be partitioned with 1GB ext2 partition. Filename with 500MB will have 500MB space for apps and sdcard need to be partitioned with 500 MB ext2 partition.
. Partition sdcard using Minitool Partition Wizard.
. This Lagfix will format sdcard second partition as ext2 and copy /data to ext2 and mount.
. This Lagfix will not factory reset. You will have same data and apps.
. You can remove this Lagfix and you will have same data as on when you applied lagfix.
. I have tested it on JPF and it should work in any FROYO or ECLAIR ROM.
How to Install:
1) Root your phone
2) Partition sdcard using minitool partition wizard (sdcard 2nd partition must be ext2 and size should be over 1GB)
2) Install busybox 1.17.
3) Put your phone in USB Debugging mode
4) Download appropriate Lagfix version and extract. 1GB or 512MB
4) Launch install_lagfix.bat
5) Your phone will reboot twice, then you can enjoy
How to Remove:
1) Launch remove_lagfix.bat

Do not apply this lagfix. PM me if you still want to apply. I will modify it for you.

Did you formatted it? I think you only partitioned sdcard. First partition sdcard and then format sdcard. I will add a screen shot to my post.

i formated it with windows manager, i will try.

It's ok. I'm going to buy sd card with more space after that, i will try it

Can you make it more simple please

created partitions, formated and no luck

Why do we need 1GB ext2? Does it use ext2 partition as application storage and fat as mass storage to share with pc? Can I use ap2sd with Eclair. I think 512MB are more than enough for applications, and there will be more room for music etc. If you can make a second version it would be great!

WHen formatting the SD Card, which partition should we format:
Ext2 or Fat

i tried format fat without ext2 and tried both, but same result phone don't see my card

same is the case with me... My phone doesnt see SD Card but detects when i remove it...

.
ok, ill try it now and then i will report back. also does this work on custom roms like motafocas JPF?

i tried permutation and combination and mine worked
What my final status is:
Fat 32: set to active and primary
ext 2: set to none and primary
Formatted fat32 and it worked.
Guys pls try this and urs will also work
Trying lagfix

my sd card even pc don't see, but phone see, only i can't format it in phone

how to set active?

Attached instructions for formatting sdcard and attached another lagfix version. Lagfix with file name 1GB will give you 1GB space for apps and need 1GB ext2 partition on sdcard and Filename with 500MB will give 500MB for apps and need 500 MB sdcard ext2 partition.

Interesting. Will try this with the custom ROM.
I have a 8GB SDCard, what should I do? Create a partition of 1GB which will give me 1gb for apps, and what about that 1gb ext2 partition? Should I make it bigger if I have a bigger sdcard?

As I understand the ext2 partinion is an extention to the internal storage memory. The phone thinks that there is 500MB or 1GB internal memory.
The fat partition is for mass storage use.
Thank you Apollo5801 for the second version! It's nice to see that there are people who can listen our needs!
I will try it as soon as my pc recognize my phone...

Hi man,
Using Windows's Sh1t tools or using *nix system format your SD using:
( under linux )
Code:
#!/bin/sh
dd if=/dev/zero of=/dev/sd** # where ** are your sd's proc
fdisk /dev/sd* # * are your main device, like sdb or sdc
mkdosfs -F 32 /dev/s*** # where *** are sdb1 or sdc1
Insert again your sd into sd slot
Have u applied some init.d tweaks? like thunderbolt or same?

Isnt this my problem
I have no format problem but mount problem.... my telefon muont internel memory in phone my internal sd in sd card an my sd ist mount...i cant install app... my telephone in memory sd have internal sd memory but if i go in external sd in root explorer i find my 8gb sd... but i cant use it for app and ohter ....

You tried it when the phone is switched on?
Because, I had the same problem.
A 32-GB SD card was nt being recognized and I did this a couple of times.
The phone lagged,but, the card was recognized at last

backup your file in recovery mode.. then wipe cache and factory reset.. if your sdcard works just restore back ur data in recovery mode..

Phone Storage partitions messed up after flashing cyanogenmod. Help please.

So a while back I flashed Cyanogen on my Motorola G 2015 just to test and see what's up. Today I went back to stock rom, rooted and modified the heck out of it. I followed the popular XDA fastboot flashing method POST and got the "official" stock rom from this thread (It said modified in the bootloader after I flashed it 100% correctly, BEFORE I started to root and mod it myself, weird huh?) So back to the problem. My partitions are completely messed up now. It's not what it was before (I think). The Internal Storage is mounted on two separate points and my SD card gets mounted as something wierd. Here are all the screenshots you need. Please tell me how to make it normal again.
Somehow here it looks like everything is fine.

YET if I format it as adoptable storage, ie. as internal sd card I can't even find it, nor can any app detect it. (But I can actually use it to put apps in it via the storage options)
First lets see the vold.fstab file
I've never seen something liket this.
my /mnt/ folder
I found my SD card partition in /mnt/media_rw with a weird number FC36-1DFE.
Here is my SDCARD1
500mb, nice partition. Much wow
up until now this is all in INTERNAL STORAGE the only EXTERNAL ( MY 32gb sandisk microsd) with the weird number FC36-1DFE is the next screenshot
When I moved these screenshots to my SD card from my internal, my pc doesn't even see them. and if I try to move from internal to sd via PC, it just doesn't work (SOME TIMES).
???????????????
Finally the illusive internal storage !
but this is where the fun part actually begins
Here is the same damn internal storage in a different directory
Storage folder
I might be over exaggerating, cause I'm new at this. But I have major problems with my sd card and internal one, some things don't work right, and all this that I saw and screenshot looks dodgy as hell and not quite right. Or maybe everything is fine and I'm a retard? You guys be the judge, please help or explain what the hell is going on. :crying:

If this is normal please say so in a reply, if not, guys please help. Bump.

It sounds normal, maybe it's just how the root browser is picking it up. Back when I had formatted my SD Card as internal storage, it also had the weird name of yours, like FC36-1DFE, but only different. I'm sure it works just fine, but a way you could test is to install an app and then unmount the SD Card, and check if the app is inaccessible anymore.

Same here. But apps(even root apps like Titanium Backup) are unable to write to the SD card. When I use TB to try to back up to the SD Card, it says directory is not writable.

There is an easy fix for that, make Titanium Backup folder on your SD card, go to the app then menu, then preferences then backup folder location, select storage provider, document provider storage, now if you have the stock explorer as default select the 3 dots on the upper right and select show SD card then select the 3 lines on top left, select your SD card then press select on your bottom right side, now select the Titanium Backup folder u made and restart the app.

That's what I did. It says the directory is not writable. Backups fail.

Try to go to root explorer, find your SD card mine is storage/bunch of numbers... long press your SD card folder in /storage and press 3 dots on upper right then press permissions, press octal and then insert 771 then press OK and try again with what I wrote I last post.

My SD card is not formatted as internal and it shows with those numbers.. The problem is that when I do format it as internal storage it disappears for apps instead of being the only one showed like before, since in MM when you format your SD card as internal the internal storage disappears and not the other way around :/

SD problem for hardcore problem solving users

There is not a 'decrypt sd card' feature at the phone too My Android is 7.0
I tried almost everything from software, minitool, easeus, diskinternals, diskgenius.... Even i see the partition of the SD card i can't restore it (Android 6.0 ARMMeta Partition and Android 6.0 ARM EXT Partition)
The problem started when the phone literally rebooted on its own when i played a Clash Royale using (NOX-app++ many accounts tool _guide) It rebooted with a message to reinsert the SD card and here is where the problem started I search for malware with 4 different programs and i don't think it's ransomware or something related with a virus
You people are my only solution because i have some photos in there i don't want to lose....
Thanks, every one for his time
I attach related photos of the problem (from the storage, sd card contents, security.)

Does this look to you as partition problem ?
The fact that is main storage means it is encrypted so if i move the main storage back to internal memory will it unlock ?
Any ideaas ?

I fired Ubuntu with fsck to see if there is a something that can be fixed but looks like as you said before the internal format of the SD (i double checked it and saw at the phone that give you the option to format it as portable so the internal format is already used) had a custom format type outside of the ordinary
SO i assume the SD is format as internal with a custom format due to encoding and that put us to the encoding section
If the keys were damaged or lost the internal storage of the native phone shouldn't boot too, right ?
However, the internal storage works fine and only the SD is not recognizable reporting 0 files (but keeping the total of GB that are used even if it doesn't report files)
How do you think i can decrypt the SD when i don't have the option in security ?

[Solved] Capacity issue - external SD card

Hi there,
A SD card (64 GB) displayed different capacities
- in computer;
- in recovery.

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
When I tried to back up data partition in recovery, it showed the message "Not enough free space on storage", but SD card functioned in full capacity on computer.
I tried
1. in recovery
- repair;
- resize;
- change to ex2 and back to ext4.
2. flashing a new recovery (twrp & orangefox)
3. formatting it on computer.
The issue prevailed.
How to fix it?
Thanks in advance.

Format the SD card as internal storage (keyword: portable storage).

If you choose to format the SD card as internal storage ( keyword: portable storage ) it should fix the problem.

formatting as internal/adoptable storage (opposite of portable storage) will encrypt MicroSD card and provide ext4 file system to this phone only. you can no longer remove it and read it in other devices, like card reader on PC. you should at least backup /data/misc/vold in case you want to decrypt on PC.
you are using FAT32 (vfat) with maximum file size limit 4 GiB per file for userdata partition image that is larger than the file system type allows.
aIecxs said:
consider this does not work on FAT32 make sure MicroSD card is formatted exFAT and 43.img file size on MicroSD card is actually larger than 4 GiB.

you can circumvent this by compressing + splitting file into junks
RaTr said:
Finally, I choose to use that option with some modifications because vfat doesn't support files larger than 4GB.
Code:
dd if=/dev/block/bootdevice/by-name/userdata conv=noerror,sync bs=100M | gzip -c | split -b1000000000 - mybackup.img.gz

Most phones support exFAT file system in alternative to FAT32. Formatting as external/portable storage may work depending on default file system type. If you want to have control about file system type, format manually (one can't choose in menu).
