install adb drivers.
Unzip and run data2loop.bat.
thanks ： Dexter_nlb ownhere

What is data2loop? Please elaborate.

Yeah what is that, and are there any drawback to using it?

i am guessing this is some sort of reallocation in the programming, so some programming terminology and not actually something u install....lol, i wish i had experience in this!

I would submit that it is programming, but also something that is installed to take advantage of the great hardware we have.

create a 512m loopback device,moving some data into the device, this can acheive rapid read and write on buffer data , such as the data under /data.

Is there a reason we r not sharing the wealth...lol. I am guessing this is something that will have to be added to the ROM? Imagine this and ext4! Whew! we might actually have something. If only Honeycomb source was out and viewsonic gave it to the developers....lol

Do we just place inandop.sh and dataloop.bat in system/ect and reboot?

run dataloop.bat on your pc.
install adb drivers first

can you wrap this up in a zip for those that have ADB issues?

Download and unzip the file on your PC which has a ADb connection to yout GT.
Then run the include data2loop.bat, this will install all the files.
Just like install any update, MAKE SURE you BACKUP your system first.

You beat my ext4 fix to the punch. But I like the way you packaged this up.
Just an explanation for what I believe chenglu is doing here -
His kernel enables loop devices, although I think they may be enabled by default too (http://en.wikipedia.org/wiki/Loop_device).
Then the modified inandop.sh script gets run at the end of init.rc, and that script is creating a file in the data area and mounting it as a loopback device.
He is then moving the stuff from data/data, data/anr and data/app-private directories and copying over the actual contents of those directories into the newly mounted directories on the loopback device.
I am not certain why the loopback device would be so much faster than the standard filesystem access, since it's still on the same device - I think it just has to do with some of the parameters he's passing to mount it? Or simply because it's plain ext2 rather than ext3 - i.e. no journalling.
Not to knock this impressive work (it's impressive because it's deceptively simple but seems to yield - at least in benchmarking - a significant improvement), but I'm not sure about the long term data integrity side of this - is the ext2 loopback device more prone to corruption? And we seem to already have more than enough data integrity issues with our ext3 /data partitions as it is.
Also, do you know how much of the gain is just attributable to the change in how you are mounting the data partition itself (noatime, nodiratime parameters obviously speed things up too, I'd already added that to my init.rc for the plain ext3 mount of the /data partition - I see you did that too in here).

I'm going to test this for TnT Lite today - I might add it to a 3.1.5 supplement, if it seems stable.
One concern is that it replaces busybox, which might break Titanium Backup. Anyone running might want to check if TB is still working, afterwards.
EDIT: Give me 30 minutes and I'll have something generic that should work on VEGAn and TnT Lite 3.x (they share the same busybox setup). And it will an update.zip.

Patiently waiting for that update.zip =P For some reason when I try to download the usb drivers for adb it tells me access is denied... oh well.

I think, the most stable is fdisk inand 3 partions, mmcblk3p3 storage loopback device.
Yesterday I tested, scores almost. For users, it is very difficult..

[Q] Insufficient Storage :-/ What to do

Hey Guys whenever i download any apps from market i get the error Install Unsuccessful .... Insufficient storage ...
What to do :-/
Rom Hell Fire v7.2
UOT Kitchen Flashed 1
Overclocked 729 Mhz
Wildfire

delete apps or move some to SD card? If your memory is full it's logical you can't add apps

Sounds to me that a2sd is not properly set up.
I been having some issues running out of storage internaly. and after some fiddeling around with a2sd it was ok. And how to do it is posted in this rom's explanation on how to install it.
ruymanca said:
The ROM takes about 10 minutes to start for the first time since the beginning makes for a facility, I recommend formatting the memory trageta do a clean install or possibly delete the folders: ANDROID, LOST DIR ANDROID as these folders SECURE conflicts created by data from the old roms
I recommend making partitions ie swap64mb ext512 and the rest as fat32 mind too expensive or necessarily recommend formatting the card will memory or possibly delete the folders in the same android, haer all the wipes, the Rom takes a few minutes to make first start since being installed all the extras on the first boot takes 3 to 5 minutes, once this echo this start and made ​​previous settings obligation is to do a reboot for full functionality telefeno
Installation of the rom:
1. reboot in recovery mode
2. we wipes all
3. selected to install update sip
4. restart the tlf
5. enter the terminal console and register the following:

nope dint workk :-/

Type "su" first (Without Quotes), then try the a2sd command.

Can u mention it Step by Step?

Hi all, i have same issue.
Yesterday i finally rootat my Wildfire and put Cyanogenmod 7.0.3.stable on it.
Its very nice!
BUT cant allways install apps from market. I have 87mb free on inside memory and 1,7gb in sdcard... So what is problem?
What i need to do? I can full wipe all my data from telefone if somone tell me how i can do this..
Can somone help?

Use dalvik wipe from xrecovery to clean ur phone data..
Sent from my U20i using XDA Premium App

try istalling darktremor a2sd script (need to be istalled from recovery if not already integrated into your rom) and download a2sdgui from market, it's a gui for the script mentioned earlier. into recovery you have to partition your sd card too (advanced) 1024mb ext and i suggest 64mb swap, then open the app I told you (a2sdgui) and move everything to ext, dalvik cache too.

I agree with the poster above.
if you have issues with a2sd, I recommend installing A2SDGUI from market. (I assume you already have darktremors a2sd script installed). I had darktremors script working fine, but after flashing a zip file, it was not working. So I installed the A2SDGUI from darktremor and fixed the script. Now it is working. Just search the market and install it. It is great. Now I have around 168 MB free after all the installed apps.
Hope this helps,

SOLUTION TO INSUFFICIENT STORAGE:
1. Use FROYO+ default apps2sd. It gives the option to force moving of 95% of the apps to sdcard. Even root is not necessary. You can move 95% of apps only after using the adb command "adb shell pm setInstallLocation 2". This command is not even needed in cm7. And this method uses the fat/fat32 partition of sdcard not the ext partition. Specifically apps will be installed to .android_secure folder in the root of sdcard.
2. This method includes creating ext partition on sdcard and using an app called "link2sd". This is a root only app. No scripts are needed. That app has option to even link individual apps to ext partition. Also links dalvik cache.
3. Creating ext + swap partition and using dtapps2sd script. Root is required. Also custom recovery is required for flashing the script. This might be the toughest one but it is pretty awesome. Moves apps , data, dalvik cache to ext partition. Everything can be done with commands from the terminal emulator. Or you can use the "a2sdgui" app for graphical user interface.
Sent from my HTC Wildfire using XDA App

The GUI for the script is much more user-friendly than emulator terminal. And you can undo everything you did if it's not as you tought faster than from terminal.

I am not aware of how Hell Fire works. But yes for Cyanogenmod 7 I know there is a issue downloading a large application from the market. It won't download. Problem is the space.
Fix for this is few steps:
1. In Terminal type the following commands.
2. su
3. mkdir /sdcard/download-cache
4. cd /cache
5. mv download download.bak
6. ln -s /sdcard/download-cache download
Done... Now Go to market and download anything you won't get such errors..
If It Helps Don't forget Press Thank Button.

Thanks a lot!
I just get my new sd-card( 16 Gb) and install darktremor a2sd script + a2sdgui.
Works just like it says!
No more thinking what program van install and what not....

Well I just installed the MOdd Again ... and I was done
Though i bought Samsung Galaxy ace as its my second time the Touch Panel doesn't work ... first in Tattoo and den in Wildfire
So ... Thanx a lot guys for Helping

[MOD]OpenRecovery XT720 01 (2011-08-30) based on Androidiani

This is a modified OpenRecovery (Skrilaz_CZ) based on Androidiani Recovery (89luca89&Azhad) with some enhanced features for Milestone XT720.
Features:
Main OR menu streamlined
Most Androidiani menu options have been moved into OR > Other Utilities
Add ext3/4 support (thanks fjfalcon)
Added SD Card Utility (OR > SD Card Utility)
Added preference for display brightness in OR (OR > Settings > Brightness)
Added utility to reinstall orbootstrap (OR > "Other Utilities" > "Re-install orbootstrap")
New sh hijack binary will boot to fastboot bootloader if volume-down is held (OR > "Other Utilities" > "Re-install orbootstrap" to enable). This should be compatible with all ROMs and stock.
nandroid: removed ability to backup partitions that always fail (this means "Backup All" works now)
Fixed OR > "Wipe Dalvik Cache" bugs (previous OR/AOR don't clear them all)
Added OR > "Power Off" (helpful when phone is being stupid about charging)
Minor update to sdcard-info.txt output
XT720 basebands added (OR > Change Basebands)
Please note that although most Androidiani menu options have been included in the Other Utilities menu item, that does *not* mean I have tested them on XT720.
Installation:
Download link: http://www.multiupload.com/J8Q15SHP4S
Root the phone
Download OpenRecovery-XT720-01.zip (it contains /sdcard/OpenRecovery and /sdcard/OpenRecovery.zip)
Extract OpenRecovery-XT720-01.zip onto the SD card. This will create a /sdcard/OpenRecovery directory and an /sdcard/OpenRecovery.zip file.
Make sure you're not in USB access mode and install the bootstrap (using adb or Terminal):
Code:
su
cp /sdcard/OpenRecovery/orbootstrap/install_script.sh /tmp
chmod 755 /tmp/install_script.sh
/tmp/install_script.sh STR
Upgrading from OpenRecovery:
Download link: http://www.multiupload.com/J8Q15SHP4S
Make a nandroid and backup your sdcard
Download OpenRecovery-XT720-01.zip (it contains /sdcard/OpenRecovery and /sdcard/OpenRecovery.zip)
Rename the old /sdcard/OpenRecovery folder to /sdcard/OpenRecovery.bak
Extract OpenRecovery-XT720-01.zip onto the SD card. This will create a new /sdcard/OpenRecovery directory.
Optional: Move/copy all files from /sdcard/OpenRecovery.bak/updates to the new /sdcard/OpenRecovery/updates directory
Optional: Reboot into OR. Select "OR" > "Other Utilities" > "Re-install orbootstrap"
Github: https://github.com/Mioze7Ae/openrecovery_xt720
Thanks: skrilax_cz, 89luca89, Azhad, fjfalcon

Is this the same update that was posted in other topics?

No, it's not the same, its the next version. The biggest difference is this one merges Androidiani (the previous one was based on vanilla OpenRecovery). Maybe I should bold the new stuff.

Sorry about this but what does Reinstalling the Bootstrap mean? Don't we already use that for getting in the bootloader? Is it is it gets broken somehow?

If the bootloader gets broken, you won't be in OpenRecovery
Anyway, I see two reasons to use it. (1) to make 100% sure you can get back to OpenRecovery after you've flashed something experimental (say a Milestone A853 update-based ROM) or (2) you want to upgrade your bootstrap to the new version that lets you hold volume-down to boot directly into the fastboot bootloader. (i.e. in the new version volume-up==OpenRecovery, volume-down==fastboot)
Edit: that reminds me... I should make a version of the bootstrap that fixes volume-down to boot OR on Milestone XT720 running Motoroi 50R...

Very very nice... thx man

Ok so I may have run into a glitch. Hopefully it is just mine, but it has been awhile since I had updated many of the apps from the market and let me tell ya, there was a shopping list. Haha get it. Anyways, I updated them all and decided it has also been some time since I had made a backup as well.
So I went in and "tried" to make a backup of the usuals (system, data, cust, cache, cdrom and sd). I probably tried 3 or 4 times and it never backed anything up. I even deleted the openrecovery folder and re-unzipped and replaced it and tried maybe another 3 times. It would just hang on the system dumping part for 15+mins (which is way too long).
I rebooted and put the original MZor back in there (the one w/o all the AOR stuff in it-for reference). Booted into recovery and boom, made the full backup in normal time. I ran checks on sd and sd-ext several times throughout and never a problem.
Has anyone else encountered this? I had been using this since it first came out and some of the utilites and all worked fine, but now that I think of it, hadnt tried to make a back up until last night.
***Side question: Since the beginning when I first learned how to make a backup, I read that you should backup system, data, cust, cache, cdrom and sd(if neccessary). My question is why do we and does it matter if we back up the cust, cache and cdrom parts? Wouldn't these get repopulated anyways at first boot? Would everything work if we just restored system, data and sd (again if neccessary)

@Mioze7Ae
can you please compile a standalone APK installer version of the new open recovery for XT720?
after reading the instructions i noticed, it requires an existing open recovery already installed to apply the above updates

I tried but my re-compiled version of the OpenRecovery.apk just FC'd.
Thanks for this Mioze7Ae, this is really sweet!

Am I missing out something here? I don't seem to be able to get the additional OR menu to convert to EXT4. I flashed back to Singapore 2.1 and have rooted. Removed the previous Open Recovery folder but where do I get the OpenRecovery.apk? Do I use back the previous version?

You can use Dexter's OpenRecovery.apk to install Open Recovery & then follow Mioze7Ae's instructions in the OP to update it.

Not sure what effect it even has, but the set timezone seems to be backwards ... Selecting GMT-7 runs /bin/timezone.sh GMT+7 and selecting GMT+7 runs /bin/timezone.sh GMT-7

Hey guys, hope you can provide me with a clearer instruction. I have done exactly as per the instructions and now when I boot into recovery, I don't see the extra option to convert to EXT4. The only things I see in the menu is:
Motorola MILESTONE XT720 Open Recovery
Version 1.46
Created by Skrilax_CZ
Use Volume Up/Down to highlight:
Camera_Mode key to select.
Main Menu
Reboot Menu
Settings
USB Mass Storage Mode
Nandroid
Application Menu
Run Script
Apply Update
Wipe Dalvik Cache
Wipe Data / Factory Reset
Wipe Cache Partition
What am I doing wrong? The phone is still running 2.1 update 1 but it's rooted.

It looks like you're running the original OpenRecovery. You need to replace the OpenRecovery folder on the sdcard with the version from the OpenRecovery-XT720-01.zip.
I think I can see how the instructions about renaming might be confusing so I tweaked the phrasing a little bit.

Thanks for the reply Mioze7Ae but I followed exactly as your instructions. Here's what I've done:
-Flashed singapore_STR_U2_01.1E.0
-Rooted with SuperOneClick
-Extracted and transferred to SD the OpenRecovery folder, OpenRecovery.zip and the original OpenRecovery.apk file.
-Ran OpenRecovery.apk
-Install Recovery System. Install Sucess.
-Recovery Boot and that's where it boots into the old OR.
It's the same if I use the OpenRecovery folder provided by hellmonger in The XT720 XDA Special Final RC2 "Hellmonger Edition"

Mioze, can you also add a wipe battery stats in your modified openrecovery? comes in handy when we flash a new rom or restore a nandroid so we dont have to use the battery calibrating app.

[Script]New "Low Storage" Notification fix

Here we go !
Starting point is from CyanogenMod Captivate forum and some improvement were added here and there. Credits are recalled and came from this thread : [SCRIPT][CM7/9] /datadata/ low storage notification lagless fix - init.d script.
Background :
CyanogenMod (CM) based roms on our I9000 (and brothers) uses a small and fast flash chip to store application datas. This make the rom smooth and sweet ... This chip is mounted as /datadata and is about 170Mo.
With a lot of apps (or apps storing lots of stuff there) we faced a "Low storage" notification and our phone becomes laggy.
The first idea was to move this /datadata to /data (about 2Go) whose have a lot of free space. This works but the phone became laggy.
Then some others devs think about moving back to /datadata frequently accessed files (sqlite database and xml preferences files). First as scripts part then as flashed zip file. The phone becames smoother but not like a "vanilla" CM rom. This is the 1103 datafix in thread linked previously.
An xda user suggested to let on /data only library files and move back all other stuff to /datadata. These lib files are only accessed (when used by users) in read mode so the ext4 /data partition is efficient in this way and phone becomes smoother as "vanilla" CM roms. This is the 2903 datafix I made and post in previously linked xda thread.
But with this latest datafix, applications cache are stored in /datadata and recent Google apps (like Chrome) fulfilled it quickly : the "Low storage" notification is back !
Next solution :
Like 2903 datafix, only libraries ("lib" and "libs" subdirectories) stay on /data by default.
BUT unlike it you could choose which apps will also store their cache in /data. And this is REVERSIBLE : if one of selected app becomes laggy you could move back its cache onto /datadata
How to use it :
Make a nandroid backup
Just grab the zip file and flash it in recovery
At reboot, it will revert previous datafix (if there is one) and apply this one. So first boot could take more time (5 minutes max) than "normal" boot.
It also creates a "datafix" directory in /data/local with two files : "move_cache.txt" and "skip_apps.txt".
Just edit the first file (root needed) to add apps whose cache will go back to /data at next boot :
Code:
com.android.chrome
org.mozilla.firefox_beta
will put Google Chrome and Firefox Beta cache on /data. All others apps cache will go to /datadata.
If you want Firefox cache to go back on /datadata, just remove its line in the file and reboot.
In the "skip_apps.txt" file, just put apps you want to fully stay on /data/data. If apps was previously moved to /datadata by the datafix it won't apply; you have to add its name in "skip_apps.txt" file after installing it and before rebooting the phone. On the other hand, if you remove the apps name from "skip_apps.txt" file all but libraries will be moved to /datadata at next reboot.
Requirements :
Samsung Galaxy S based phone (GT-I9000, Vibrant, Fascinate, Captivate, etc.)
CM based rom (including CM7/9, MIUI and maybe ao(k)sp etc.)
Kernel that supports init.d scripts (latest CM9 nightly support it)
Busybox installed
A fresh nandroid backup
FAQ :
Q : There is 2 zip files, who's the good one ?
A : It depends of your kernel. With stock CM9 kernel use the Datafix20120521. With others like Devil etc., use the SDatafi20120521. The only difference is between the script name : 30datafix or S30datafix. Some recent kernels add a "S" before the init.d script name. Why ? No idea !!!
Q : Will this wipe my phone ?
A : No, it should not delete any data on your phone. But as it's not tested with every phone xda user have it's a good idea to have a fresh nandroid backup
Q : Do I need to reflash the zip file ? When ?
A : The datafix will be erased each time you upgrade/change your rom (including Nightly Builds) or your kernel (many of them "clean" the init.d directory). But if you don't install lots of apps after upgrading you don't really need to install the datafix again : without full wipe, a nandroid restore or an Odin full installation te datafix will stay on.
Q : Is there something to do when backuping my apps ?
A : Nandroid should work without specific option; Titanium Backup users should tick the Preferences > Troubleshooting settings > Follow all symbolic links option. I don't use other backup apps ...
Q : Can I use this on Samsung based rom ?
A : No ! And it's irrelevant cause Samsung roms don't have the "Low storage" issue !
Q : I'm using Slim ICS rom, do I need some busybox fixer etc. ?
A : I don't use SlimICS but all commands in my script call busybox directly so it should work. Let me know if there is still a problem with this !
Q : Why do you change naming of the zip file ?
A : Cause I want ! And it's listed directly in chronological order in terminal (or recovery) in this way.
Q : How can I know which apps use most space on /datadata :
A : Just run as root (in adb or terminal) :
Code:
du -s /datadata/*|sort -n

I put the shell script in attachement here. Just grab it on your sdcard, remove the ".txt" extension and you could run it using Scripter or equivalent (root needed). Please post here if something gone wrong when using it.
Donations :
As I spent some time (and coffee) for this (and april datafix for those following previous xda thread) I think about a donation button. Give me your advise on that please ...

But just a little "Thanks, it works great !" would be great !

Thanks for this. I kept wondering why I would run out of storage all the time. Well, now I know and you fixed it!

Hi,
Nice work.
Something I don't understand - how should I choose which apps I have their cache go to the /data partition? Apps that I frequently access? Apps that take a lot of space?

Wendigogo I've previously had an old datafix posted that moved all the files to /data/data and I've only had issues when Chrome filled the cache so Ive ran your script but now /datadata is filled and everything is FC Chrome's cache seems to be in /data/data though
any ideas?

Er.. is my datadata folder meant to be empty after applying this patch ? Phone is definitely slower.. forgot to do a nandroid too argh.
As per the other fixes.. doubt this is reversible ?

Just a stupid question.
Why Samsung Roms dont need it ?
How works the solution of Samsung?
Thanks!

Very good script. Whats your future plans for this?
It would be really good if this was made into an app that let u select the apps cache you want on /data or /datadata rather than having to edit a text document.

I've flashed this and now my /datadata partition is empty...

Something went wrong for me too
I wasn't previously using datafix,flashed it and checked my /datadata a very little time after reboot that was 128Mb free.Seemed a lot of free space comparing to the only-libs 2903 version.For the same initial configuration/apps installed i usually get about 88Mb of free space after flashing 2903.
Just a little while later i noticed a datadata folder in /datadata and free space was now 66Mb...I reboot and /datadata ended full.
Note:Users of Devil or MnIcs get after each boot a user.log (+ a .bak of the previous boot) that describe among others things init.d process,it could help to paste it here

Seems to work for me... but can someone tell me what the following folders are for and if I need them or if they're remnants of some past datafix?
/data/data.new
/data/data2
Thanks.

None would be the best choice.
Moving their cache out of /datadata can potentially make them laggy. However, some apps have massive caches (Flipboard, Chrome, Google Music, etc.); as such, these apps are unusable unless you do move their cache (or unless you have very few apps installed).

I wonder why so many people are having troubles. I'll give the script a try soon. It looks good! Thanks for your monumental contribution, Wendigogo.

Donations :
As I spent some time (and coffee) for this (and april datafix for those following previous xda thread) I think about a donation button. Give me your advise on that please ...
But just a little "Thanks, it works great !" would be great !

My vote is that you SHOULD put up a donation button, I am happy to contribute to your coffee fund (so long as you don't drink Starbuck's ;-) But since you're French, you surely have better taste than that!)

After upgrade to ver.0521 from 0329, I have the following problems:
1. There is a data.new folder, I wonder if it can be removed.
2. new installed apps haven't been moved to datadata
3. removed apps haven't been removed from datadata
I'm on cm9 0520 with devil 0.56 kernel, busybox updated to 1.20.
By the way, the scripts run well under scripts manager.

I GUESS it is easy to manage across all devices for the cm team without having to write specific code for different devices.

+1. Why do we need those folders to be kept in data? But when I tried to delete data.new I got FC's for all of my apps. Seems that data.new has replaced data/data folder.
And one more. I wanted to move com.android.email to data/data completely and edited skip_apps.txt. But when I check datadata folder with Disk Usage app - com.android.email still remains there.
What have I done wrong?

I find that 0521 version uses busybox for copy /move /mkdir operation, which is different from old versions.

After 3 reboots /datadata is still empty...

[GUIDE] Formatting EXT4 to F2FS without losing internal storage & data

Hi everyone,
This is a simple guide on how to fomat ext4 to f2fs without losing any of the internal storage & data.
Cuz, nowadays many ROMs, specially the new marshmallow ROMs are having F2FS support. And f2fs has much better I/O perfomance when compared to Ext4 (it really boosts your bacon's read & write speed)
IMPORTANT: F2FS is useful only if the ROM & Kernel which you are using supports F2FS (it shoud be written in the description in the thread of the ROM & kernel). If it doesnt support, & you formatted partitions as f2fs, then maybe you wont be able to boot.
Code:
/* DISCLAIMER:

* Your warranty is... still valid?
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about steps included in this guide
* before formatting the phone! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*
*/
First of all what is F2FS?
F2FS (Flash-Friendly File System) is a flash file system initially developed by Samsung Electronics for the Linux kernel.
The motive for F2FS was to build a file systemthat, from the start, takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks,eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.
Benefits:
- Much Increased I/O speed
- Increase life span of flash storage due to less write required
- Doesn't suffer file size limitation of 4GB​
Why F2FS is better than Ext4?
Because, it has much better I/O perfomance when compared to Ext4. It also has much higher write speeds. It is specially meant for eMMC card & to use its full potential. See various benchmarks & comparison of Ext4 & F2FS here: http://forum.xda-developers.com/showthread.php?t=2697069​
I even got very high UX I/O Perfomance Score in AnTuTu Benchmark (much higher than my old ext4 exodus cm12 ux score) (UX Score 29513 out of total score 56581) (Sultanxda CM13 build 4.4.2016, lightning kernel, /data & /cache formatted as F2FS): https://forums.oneplus.net/threads/cm13-what-is-your-antutu-score-in-cm13.440380 (see screenshot). ​
Why am I making a seperate guide? Isnt this very easy?
Cuz, many people (even I before) didnt know that formatting /data, /system & /cache to f2fs would wipe the internal storage too, and at later would end up crying after losing their precious internal storage files. This had happened to me a few weeks ago. And this involves some other steps too. So I am making this guide so that others wont lose their precious files.​​
Pre-Requisites:
OnePlus One (lol) & working usb cable
TWRP 3.0.1
ROM & Kernel that supports F2FS
Windows Laptop/PC with ADB Drivers & ADB 1.0.32 installed (how to install adb driver & adb is given in Steps 4 & 5) & with atleast 60GB Space in your PC.
70% battery in your bacon atleast.
Procedure:
If you are gonna wipe /system & /data for flashing new ROM (like a new cm13 rom), then first take titanium backup of all the required stuff.
Reboot to recovery mode (TWRP)
In TWRP, Go to Backup >> Tick all the partitions >> Go to options tab & enable compression (this will make the backup process slower but will make the backup files smaller, optional) >> Swipe to backup >> Wait until backup gets over. Dont cancel.
After the backup process is complete, go to twrp home >> Mount >> Enable MTP (if the button shows Disable MTP, that means MTP is already enabled) >> Now connect your opo to computer/laptop. In My Computer or This PC, it should show up as A0001 >> Now open the device A0001 in This PC/Computer >> Internal Storage >> Select everything (dont miss anything) >> Right click > Copy >> Now make a folder anywhere (I made it in root of C: drive) >> paste everything. This will take some time, wait till everything gets over. MTP is too slow & sometimes some files do not copy properly. Instead, do this failproof ADB method (for windows user): Install Universal ADB Driver from here (ignore if you have already installed adb)
Now download minimal adb & fastboot from here >> Open the downloaded file (Its a setup wizard) >> when it asks for installation path, change the default path to "C:\adb" (without quotes) & install it.
Now open command prompt (press win+R from keyboard, type cmd & press enter) & type the following one by one:
Code:
cd c:\adb
adb pull -p /sdcard c:\bacon_full_backup
The full backup is gonna take several minutes. Relax with some music until then. :good:
Now you are ready to go! WARNING: This step will wipe your /system completely. But dont worry. Everything is safe in your PC. Now go to TWRP Home >> Wipe >> Advanced Wipe >> tick system (verify if your ROM & kernel supports /system as f2fs, else skip this step) >> Repair or Change File System >> Change File System >> F2FS >> Swipe to change. Now your system partition is cleanly formatted to F2FS. [@Sultanxda's CM13 does not support /system as f2fs]
WARNING: This step will wipe your /data & internal storage (sdcard) completely!! . Go to TWRP Home >> Wipe >> Advanced Wipe >> tick data (verify if your ROM & kernel supports /data as f2fs, else skip this step) >> Repair or Change File System >> Change File System >> F2FS >> Swipe to change. Now your data partition is cleanly formatted to F2FS, & internal storage is empty (dont get freaked out, everything is in your PC!). [@Sultanxda's CM13 supports /data as f2fs.]
This step will wipe your /cache. Now go to TWRP Home >> Wipe >> Advanced Wipe >> tick cache (verify if your ROM & kernel supports /cache as f2fs, else skip this step) >> Repair or Change File System >> Change File System >> F2FS >> Swipe to change. Now your cache partition is cleanly formatted to F2FS. [@Sultanxda's CM13 supports /cache as f2fs.]
If you are flashing new ROM after wiping data & system, then skip the steps 12 & 13.
Now plug your opo into your PC & copy everything of the internal storage, which you copied erlier to your PC, back into the internal storage of OPO. This will take several minutes. MTP transfer is too slow. Instead, do the ADB method: Open a command prompt & type these commands one by one wait till it completes (will take a long time):
Code:
cd c:\adb
adb push -p c:\bacon_full_backup /sdcard
Now go to TWRP Home >> Settings >> tick use rm -rf instead of formatting (else while restoring the twrp backups, twrp will reformat the partitions as ext4 again).
Now go to twrp home >> restore >> select the latest backup (see the date & time in the name of the backup if you have multiple backups) >> tick every partitions >> tick enable md5 verification >> Swipe to restore.
Done.
Voila! Now your device is formatted as F2FS! Enjoy the much faster I/O read & write speed.
I actually made this guide here: https://forums.oneplus.net/threads/...-without-losing-internal-storage-data.439999/ & copy pasted in xda forum.

cool but i thought there would be no backup involved like windows where i changed from mbr to gpt without damaging data

Umm, So if I use 6.0.1 sultan I can format to f2fs except 'system' directory right?
That mean I need to skip step 6 . Am I right ?
Sorry for newb question XD

Oh my god.... This was the most obvious guide I have ever come across on XDA.... Please make a guide on how backup and restore my apps if I overheat and burn my phone?

No the author has has definitely put a great amount t of efforts to write.... I give him that.... I came to guide to find some other way of backing up the data from your internal storage partition directly... But copying g onto your laptop is something almost what everyone does... I think the warning that the OP gave after how formatting would erase the complete partition... I think it should indicate as to what happens.... He has stated that clearly too...
I was looking g for a better alternative

Might make sense to make a list of Roms and kernels that support F2FS, since people will come here out curiousity, and it would be the next logical step to find and flash a rom that support it.

some things about 12 item:
for me adb dont want to work, because i wipe all partitions and didnt install the rom. After installing ROM, go to develop options and check adb debug, only after this step adb command in cmd was working well.

If i only convert to f2fs CACHE, so it lose internal storage & data?

Nope

so, can i do this tutorial on lastest stock cm13? or need custom rom?

Is F2FS stable yet? Last I heard it caused all sort of data corruption, freezing, etc.

How can I put a ROM on my phone after converting data and cache? In TWRP, mounting doesn't give me a storage device in Windows, and using ADB Sideload, it just gets stuck on 'starting service'. I plan to move from sultans CM12.1 up to CM13 but I dont know how to load a ROM zip onto the phone after converting the file system?

For me, who just wants to flash (and destroy and flash and destroy again - 2nd bootloader ftw!) his 7 year old Samsung Galaxy S1, is this completely new. Never heard of f2fs before today.
For the SGS1, only roms from 5.x on supports f2sf. But its manditory to try the 6.x roms.
I thankfully stumbled across this guide - now im only in the need to figure out, which from with version on TWRP & CWM can do this trick, where i can found them and what i need to do, to be able to flash them. (If your handset is on android 2.2/2.3, its not that easy to change to an up-to-date version)

Yup sorry for the mistake. Its a slash instead of a backslash in adb pull \sdcard.I have updated it.
Someone pointed out the same mistake in my OPO forums thread and had fixed it, but forgot to fix it in XDA thread.

hello i read the guide to convert filesystem, byt when i tick partition system and changhe file system with twrp 3.1.0 i can not chose f2fs is not present why? only ext2 ext 3 ext4 etc but not f2fs? why???
thanks
