you need root for flashing custom roms that are not HTC/Google branded
you use recovery for backup your old Rom before you flash the new one ( so if brick it you can flash your old backup again )
Thats what i know

1. Rooting means get the root access right, since Linux system has very strict access control, without root access it is not possible to do any system level changes (including flashing the customized rom, change the system settings...)
2. Recovery is a special partition located in the rom, actually a recovery is a pre-built system image (a small fixed Linux system) that can be boot. With booting the recovery you can do a lot of changes to the normal booting system (ie. the /system and change the kernel with located in the boot partition in the rom). And with a lot of person's effort, the recovery image now getting easier by many preconfiged script on the menu, so that can get the system update, backup/restore and other system level changes)

[CWM-APP] full_wipe && easy_upgrade_wipe ZIPs [EXT2,3&4], last updated [2014-06-23]
Hello everybody!
I got inspired by mero01, who made similar tools for my previous mobile phone, the HTC Desire HD.
Imho a new version of an Android ROM should NEVER ever do a full wipe. Personally I prefer to wipe on my own AND to _personally_ have the option which file system is going to be used.
That's why I've created my own zip files, which do either a FULL_wipe or an easy_upgrade_wipe.
These zip files could work on multiple phones, but they are only tested and confirmed to be working on the LG Optimus 2x (P990). Just for the sake I've also implemented a check inside of them if that's the phone, which the wipe(s) are performed on.
**** !NONE WILL FORMAT YOUR SDCARD! ****
I DON'T TAKE ANY RESPONSIBILTY FOR DATA LOSS OR ANY DAMAGE CAUSED TO YOUR DEVICES. USE AT YOUR OWN RISK!!! UNDO IS NOT POSSIBLE!
PREREQUISITES:
* Clockworkmod Recovery (recommended version: v6.0.2.5)
INSTRUCTIONS FOR EVERY FILE:
Code:
1. Download the zip file you want.
2. Place it anywhere in your /sdcard/
3. Reboot into CWM recovery
4. Install zip from sdcard
5. CONFRIM --- CAUTION! THIS IS UNDO-ABLE!!!
6. done :)
7. Don't reboot, flash any rom you want
8. Flash it
9. Reboot and have fun! ;)
FULL_WIPES
This patch comes in two versions (EXT3 and EXT4) and needs to be applied prior to the flash of any ROM. It will WIPE your device and format all partitions either in EXT3 or EXT4.
Wipes performed:
* SYSTEM
* DATA
* CACHE (always EXT3)
* Cleaned temporary SDCARD data ("/sdcard/.data/navigator/Data/Temporary")
EASY_UPGRADE_WIPES
These patches also come in the previous two versions (EXT3 and EXT4) and there is an additonal lite variation, which won't wipe your dalvik cache. Use the easy upgrade wipes if you DON'T want to remove your data (especially useful for ROM upgrades)!
Wipes performed:
* SYSTEM
* CACHE (always EXT3)
* non lite versions: Wipes the dalvik cache on DATA
* Cleaned temporary SDCARD data ("/sdcard/.data/navigator/Data/Temporary")
NO_JOURNAL
This won't do any wipes, but will remove the JOURNAL(S) on your file systems. If it gets applied to EXT3 partitions it clearly results in EXT2 partitions.
You will get the fastest possible EXT* file systems if it is applied to the EXT4 partitions.
It can also be applied on already existing file systems, although I'd suggest to use a clean file system. Make a backup if you still want to perform it, because it can be dangerous!
Wipes performed:
* NONE
CHANGELOG:
Code:
[U]2014-06-23[/U]
- New LITE easy upgrade wipes available, which won't clean your dalvik cache.
[U]2012-12-10[/U]

Frequently asked questions (FAQ):
What is the difference between the o and n versions?
The o stands for OLD-, whereas n is an abbreviation for NEW-partitioning layout. Unfortunately LG changed the location of the data partition (from mmcblk0p8 to mmcblk0p9).

so what's the difference between the erase/reset data factory on CWM???

By default CWM will only format your partitions in ext3. Now you can choose ext4 which is usefull for ROMs/kernel with ext4 support but do not format the partitions in ext4. Also, you can use ext2 now the easy way.

Exactly. Thanks for the answer koboltzz.
For the HTC Desire HD there was also an EXT4 version of CWM available, which changed the default algorithms of the "Wipe data/Factory reset" and the "Format" options to EXT4.
But with the latter possibility you loose the ability to format EXT3 partitions. That's also why I always used mero01's zip files to accomplish wipes.
Imho it's the best option, because if you REMOVE the formatting lines from the ROMs you want to flash it's absolutely no problem to also use an EXT3 designed ROM (like Hypnos2X for example) on EXT4 file systems (that's the operating system I'm currently on).
And I tell you also because I dislike the FULL wipes on nearly every ROM available for the LG Optimus 2X. If you have a problem and just want to reinstall the ROM without loosing any data there is no way to do that.
Yes, an easy wipe should always be done by the standard ROM zip itself - of course... but I've always also removed those lines, because that way you also get the freedom of the file system.
It's up to you...

sadly, I must report, that 0-full_wipe_0.3_ext4.zip is not working as expected.
Using it and after that flashing Fr19 with ext4 Kernel (from modaco) -> no boot at all ->freezing
This will not happen, if you first do a fullwipe by cwm (ext3), then flash Fr19 and after that use the universal converter to ext4 from benee.
But this only changes data and system partition to ext4 by default.
There is definitely something wrong with the script, an other example:
First flashing 0-full_wipe_0.3_ext4.zip
after that Fr19 ROM (up to this point it would have been a bootfreeze, look above)
and after that flashing universal converter to ext4, phone will boot now, but will not be able to install any app 'there is insufficient space' (which is totally not true), most likely because cache partition is fu.cked up by 0-full_wipe_0.3_ext4.zip
Time for version 0.4

hey dr4go got something weird here...
when i flash your ext3 zip everything is fine atleast the mount command say so
but then when i want to convert them to ext2 something really weirds occur the system partition becomes ext2 but the data and cache partition become ext4 according to the mount command using recovery 5.0.2.7R2

Here is the convert tool made by Topogigi, and slightly modified by me to include /system conversion.
/cache has not the same parameters it seems.

First (and second) post(s) updated.
And I'll promise you also to release something bigger next time. Guesses won't be commented.

Everything fine here! Nice to see you too. I finally found some free time and also motivation, because of the marvellously working CyanogenMod 10 on our phones. It's unbelievable... I was nearly freaking out when reading the notice.
And you? How are you? Hopefully everything is also great on your side?

What exactly did you do? And which ROM did you try to flash afterwards? Imho the zips should be fixed now - I didn't encounter a single problem since using them.

i try it with ICS 28E and 28G for my Ghostrider Aroma Rom with new Partition Layout,but when i use ext3 or ext4 i got a Bootloop,i put the stuff in the Updater-Script,all runs with Aroma and lokks fine but when i reboot,i got the Bootloop

[Utility] CleanFlasher / & Get your phone ready for 4.3

Some words about my little Script:
I would describe myself as a flashoholic and kinda perfectionist.
I try a lot of different Roms and to get the best results I always want to start from scratch and have a clean base for the new Rom.
So I decided to write a little script that automates the process for me. :lazy:​
Based upon: Android 4.3 AOSP (JWR66Y)
There will be different versions:
For all versions: THIS WILL WIPE YOUR USERDATA! Make sure you have a backup!
1. Coming from a 4.2 rom:
- flashing latest 4.3 bootloader
- flashing latest 4.3 radio
- formatting system partition
- formatting userdata partition
- formatting cache partition
- flash stock boot.img
- flash stock recovery.img
- write original factory system partition to the device
- write original factory userdata partition to the device
- write original factory cache partition to the device
- again formatting system partition
- again formatting userdata partition
- again formatting cache partition
Now you have a complete "empty" device ready for every new 4.3 Rom.
Your device WON'T boot up until you flash a Rom in Recovery or via fastboot!
Download
2. Just clean install (already 4.3):
- formatting system partition
- formatting userdata partition
- formatting cache partition
- flash stock boot.img
- flash stock recovery.img
Your device WON'T boot up until you flash a Rom in Recovery or via fastboot!
Download
3. Clean install for paranoids (already 4.3):
- formatting system partition
- formatting userdata partition
- formatting cache partition
- flash stock boot.img
- flash stock recovery.img
- write original factory system partition to the device
- write original factory userdata partition to the device
- write original factory cache partition to the device
- again formatting system partition
- again formatting userdata partition
- again formatting cache partition
Your device WON'T boot up until you flash a Rom in Recovery or via fastboot!
Download
Instructions:
- Download file
- Unpack it (using e.g. 7zip or WinRar)
- open the folder
- put your device into fastboot mode by either chosing it in your reboot menu or by powering off the phone and then
push and hold Vol+, Vol- and the power button until you are in fastboot mode
- connect the device to your PC
- execute the "make_it_happen.bat" in the folder
- hold on tight! Your device will reboot a few times during the process (don't worry)
- enjoy fresh and empty Nexus 4.
Note:
This is ONLY for the Nexus 4! Don't try it with other devices! It won't work.
You can easily replace the included files with e.g. your prefered kernel (boot.img) or your prefered recovery (recovery.img).
Just extract the *.zip and replace the files! (Be careful with the spelling.) This might save you some time if you always want to start from the same fresh base.
Going to release a version that lets you decide which version you want to use or what you want to flash/erase/format. -> Kinda AiO Version of this little script.
If people are interestes in it, I might release a version of this script that lets you revert to either AOSP stock or Google Factory Image stock (both bootable) without wiping partitions after the flash. (Of course CLEAN.)
At the moment these versions are in order you are directly going to flash a custom rom to your device. Just tell me.
Thanks to:
Google for their factory Image.
franciscofranco for his precompiled AOSP source

Your device WON'T boot up until you do not flash a Rom in Recovery or via fastboot!

Yes you are right. I should add that.
Wrote a short statement in the "Notes" section about that.

I recently got a Nexus 4, probably on 4.1.
Anyway, flashing to a 4.3 custom rom and the internal storage is a bit weird - lots of sdcard simlinks with folders named 0, legacy, emulated in the storage directory. I saw a thread that said that this happens after updating from an earlier revision of android and is supposed to be a backup of the old sdcard partition as it was, but it's quite confusing and doesn't seem to work well. I can't seem to get rid of the simlinks within a rooted file browser, not that I am completely sure of how to do that, anyway.
Now, the actual question - will using this get rid of the confusing way my internal storage's sdcard directory is structured, returning it to something simple like "/storage/sdcard/mystuff"?

Yes. Method 1.) should exactly do what you want.
Be sure you update your recovery to the latest version. E.g Clockworkmod or Twrp.
After you have succesfully used method 1.) stay in bootloader.
- Download the *.img file of your prefered recovery.
- open terminal and flash the recovery by using the following command:
- fastboot flash recovery "nameofyourrecovery".img (of coures without the " ")
- fastboot reboot-bootloader
Thats it.
Now you have a custom recovery. Boot into recovery and flash your prefered rom!

[HOWTO] Changing Filesystem to F2FS on the Sprint S4

This guide is for the Sprint Galaxy S4 only and as of now it is only compatible with two kernels: KToonsez S4 Kernel 4.4 AOSP (4/17 or later) and PoKernel 1.7 F2FS ONLY Build. This guide CANNOT be used on Touchwiz or Android 4.3 yet. I will update it when and if that becomes possible
*Disclaimer: You are doing this to your phone under your own consent. This is an experimental procedure and may not work on some hardware revisions or on devices where certain conditions are not met. You assume all the risk by flashing any of the software below or changing your filesystems. I am not responsible if your phone does not work based on the method I am describing below. Modify at your own risk.
This guide had to be updated in order to correct misinformation. The guide will follow KT's instructions explicitly until it gets to the formatting of the system partition
***If you want to format your /system partition to F2FS please read that section first as it requires steps to be taken from your currently working AOSP rom!***
First, go this link download the file:TWRP-KT.ALL-IN-1.zip
http://goo.gl/HLz4al
Formatting Data and Cache to F2FS
NOTE: Follow these steps EXACTLY, do NOT add or remove any steps, period!!!!
1. Backup everything from your internal SD to your PC or external SD, since the entire internal SD is going to get wiped out with format!!!!!!!!!!
2. Download the files from the folder that you got these instructions from (Ignore the OLD WAY folder) and SAVE TO THE EXTERNAL SD!!!
3. ONLY DO THIS STEP IF YOU ARE ON AN OLD VERSION OF MY TWRP. Flash TWRP-KT.ALL-IN-1.zip (this is what gives us the ability to format using F2FS)
4. Reboot recovery
5. Go to "Settings" and check the box to force F2FS for data and cache (you can also check the box to include /system partition if you want to convert your ROM's zip to use that too)
6. Go to "Wipe->Advanced" option and wipe the "Cache" partiton
7. Go to "Wipe->Format Data" option (THIS WIPES YOUR ENTIRE INTERNAL SD CARD, all files and folders, all gone so make a backup to your external SD or PC!!!!!!!!!!!!!)
8. This step you have 2 choices:
A. Flash your ROM/gapps to start completely fresh
B. Go to restore option and ONLY restore your "Data" (you can also restore /system if you are doing the f2fs conversion on /system partition too)
9. ONLY DO THIS STEP IF YOU INSTALLED A NEW ROM. Flash my newest kernel (needs to be a kernel dated 05.05.2014 or newer)
10. DONE!!!!!!!!!!!!!
11. KTweaker has a new option under "Tools" screen to "Get Partition info" to double check your work.
Formatting System Partition with F2FS (Required: KT SGS4 Kernel 4/28 or later!)
Steps:
1.) Before doing any F2FS conversion with the above instructions, use your currently working AOSP ROM to grab the AOSP 4.4 Kernel from HERE (4/28 or later only!) and save it to your external memory card
2.) Once it is saved reboot to recovery and install it (Flashing a kernel in TWRP is Install -> Folder where kernel is -> Click KT 4/28 kernel -> Swipe to install -> Clear cache/dalvik -> Main menu -> click advanced -> Fix Permissions -> Reboot to system)
3.) After you are back in your working AOSP ROM with KT 4/28 kernel installed, download the AOSP rom you want to use and save it to your external sd card (You can leave the filename as it is, the program will rename it for you)
4.) Open KTweaker and click "Tools" and at the very bottom choose "F2FS: Convert ROM ZIP"
5.) It will ask you to locate the file, ask if you're sure, and then it will do the conversion; upon completion the zip file that was created will have "-F2FS.zip" at the end of it
6.) Now you can follow the steps above, but when you get to step 9A you will use the "-F2FS.zip" file instead of the standard ROM file
This procedure is necessary because KTweaker changes your favorite ROM to pass the command mkfs.f2fs so that your system partition is formatted to F2FS before the files are installed. I did this myself to verify and it works a treat. One crucial step to remember though is that after you install your F2FS converted ROM you absolutely must install KT's kernel so your phone will boot.
Returning to EXT4
NOTE: Follow these steps EXACTLY, do NOT add or remove any steps, period!!!!
1. Backup everything from your internal SD to your PC or external SD, since the entire internal SD is going to get wiped out with format!!!!!!!!!!
2. Download the files from the folder that you got these instructions from (Ignore the OLD WAY folder) and SAVE TO THE EXTERNAL SD!!!
3. ONLY DO THIS STEP IF YOU ARE ON AN OLD VERSION OF MY TWRP. Flash TWRP-KT.ALL-IN-1.zip (this is what gives us the ability to format using F2FS)
4. Reboot recovery
5. Go to "Settings" and uncheck the box to force F2FS for data and cache (If you checked the box to include /system partition uncheck it first)
6. Go to "Wipe->Advanced" option and wipe the "Cache" partiton
7. Go to "Wipe->Format Data" option (THIS WIPES YOUR ENTIRE INTERNAL SD CARD, all files and folders, all gone so make a backup to your external SD or PC!!!!!!!!!!!!!)
8. This step you have 2 choices:
A. Flash your ROM/gapps to start completely fresh

9. ONLY DO THIS STEP IF YOU INSTALLED A NEW ROM. Flash my newest kernel (needs to be a kernel dated 05.05.2014 or newer)
10. DONE!!!!!!!!!!!!!
11. KTweaker has a new option under "Tools" screen to "Get Partition info" to double check your work.
FAQ
Q: Why can't I use this on Touchwiz?
A: It has been developed for the most recent Linux kernel 3.8 and has been implemented in kernels built for 4.4.x OSP builds. This isn't to say it cannot be used on Touchwiz, it is a filesystem and as long as there is a kernel that offers support for reading it installed on your device it should theoretically work on your hardware. However, this can be proven/disproven by the devs here and I will update this answer if it cannot be implemented in a backwards fashion.
Q: Are there advantages to using F2FS?
A: It is built and intended for use on flash filesystems which our devices run exclusively. So since it was developed for flash memory there will be a benefit to using it as it matures. However, this does not imply that benchmarks will increase or your whole phone will become more responsive, its intent is to have files be accessed and written more efficiently. It is supposedly also built for the long-term user who does not constantly reformat their devices because it is supposed to handle large amounts of old files and cleaning more effectively that EXT4. Source: https://www.kernel.org/doc/Documentation/filesystems/f2fs.txt
Q: Will this trip Knox?
A: No more than installing a custom recovery would. So if you already had a custom recovery (Read: TWRP, PhilZ, CWM) in place you are safe following this guide. For now of course; I do not know if there will be another iteration of Samsung software that locks down the device futher.
Q: Can I clear Cache and Dalvik to troubleshoot after changing my filesystem?
A: I tried this myself and the answer is yes. As long as you are using the F2FS custom recovery made by KToonsez you can wipe Cache and Dalvik from recovery and it will rebuild your system. Something I did notice is that first boot will stay on the splash screen longer with F2FS than with EXT4. I saw it hang on the splash screen of my Liquid rom for an extra minute before actually booting and showing cache rebuild. **Your Mileage May Vary**
Q: Why isn't the System Partition formatted into F2FS?
A: This can be done now with KTweaker. See section above.
Q: What ROMs can I use with this filesystem?
A: Any 4.4.x rom (most are 4.4.2 now) that is compatible with either KToonsez S4 AOSP kernel or Pokernel 1.7 F2FS Only.
Q: In Advanced Wipe, Preload has been added to the options of things to wipe. Should I?
A: Ktoonsez answer found HERE was that he has never wiped preload. So I suggest against it unless you know what you are doing.

Great guide OP! Always nice to have a thread to link to.
I'm sure it's been talked about but your posts doesn't mention the ramdisk files. They're listed but not talked about. Now I'm somewhat limited myself in understanding everything there is to know about these things but are those files to do with eventually formatting the system partition to f2fs?
May be worth putting a little note in there regarding those files... You know how some folks go flash crazy once in recovery lol

Hello again.. Lol
The ramdisk mod is now obsolete as it's already included in the kernel zip, which will automatically determine whether you're still on EXT4 or F2FS and make the required changes to the ramdisk accordingly. So no need to flash anything but the kernel as usual after following the steps.

OK yea I figured it was either to do with what I said or to do with the kernel obviously. Just figured I'd ask anyways

I'll be the first to admit that I wasn't entirely sure what the ramdisk files were for. I knew they might have been for advanced users considering they were offered, but not listed in the instructions. I didn't know for sure and I didn't want to use the word "obsolete" because, well, I was so wrong before
I am glad LuigiBull23 jumped in and answered that for us. I'll get it added into the the guide so future users know what they are or are not used for. Keep the questions coming, I love learning about this stuff!

I understand. A lot of people were and still are confused about these files..
In short, during the testing phases of F2FS, KT compiled a separate zip for changes to the ramdisk that in turn would reflect the EXT4/F2FS mount points as a means to avoid possible bootloops and such. It was indeed a success and as a result was included in his kernel.
Now, upon flashing the kernel it is able to determine which partitions are formatted as EXT4 or F2FS and mod the ramdisk accordingly. He only left the files on his server in case he ever needed them again. So they are most definitely OBSOLETE. You certainly wouldn't have gone wrong using the term in this case.

Updated the guide for KT's new all-in-one TWRP recovery that will allow you to switch back and forth between F2FS and EXT4. I used his exact instructions from his guide in all areas except for the system formatting section which I wrote. If you are using his custom TWRP recovery go ahead and grab the new one so you can use it in the future!

F2FS with CM11 Nightly
When I used KTweaker to convert my latest CM 11 nightly, it came back and said that it was done but could not find all the lines to modify. Is this ok?

I know it has been forever since you posted this and I apologize for the late answer, but I imagine that if you received that error you got a bad download of CM11. I've personally converted the snapshot and several nightlies of CM11 and they all passed nicely.
So for anyone getting this, if you get a similar error message: Re-download the ROM you are converting

to bad its still not possible with touchwiz, love to use f2fs on a stock rom for my sgs4-lte.
is it possible in the near future that we can use f2fs on those devices with a Samsung stock rom, using another kernel is no problem.
or is this hard to tell ?

Hello, I've been trying to use this to change my filesystem because I'm coming from CM12 and I'm trying to flash a GPE rom on my S4. But after flashing I am rebooting straight to recovery. Also I'm using the latest TWRP.

Make sure you are using a version of TWRP that support F2FS. I don't think the standard issue TWRP does. @AntaresOne has one that does support F2FS and is based on the latest version (2.8.3.0). That's the one I use. Of course, I'm hooked on his CM12 ROM as well. He does really good work!!

But doesn't it have to be in EXT4 for it to work for a GPE ROM?

You are probably right. I haven't tried the GPE ROM yet.

Yup gpe uses ext4 on all partitions because it uses tw framework

With TWRP + Backups Working Now - Which partitions make sense to backup regularly?

Until now, no my rooted Samsung Note 3 I have automatic TWRP backups running every night. This just mirrors my paranoia that I will manage to screw up something and recovery via TWRP restore is often faster/easier/more complete than trying to do anything else. I do this using the OpenRecoveryScript and have always used this backup command:
backup DSBCR DailyBackup
Which gets data, system, boot, cache, and recovery. I plan to do the same now that I know to put the OpenRecoveryScript into /data/cache/recovery instead of /cache/recovery on my Note 3.
So my question here is what partitions make sense to backup on the V40? And by "sense" I mean something likely to change or get broken (by errant apps or, more likely, my own doing) AND having the ability to restore using TWRP restore from backup.
There are a ton of partitions on this device - most of which I know little/nothing about. I do know that the system and vendor partitions have duplicates and so those are not needed, I guess. And it seems that the OpenRecoveryScript backup command has no way to handle anything except the following anyway:
S: system,
D: data,
C: cache,
R: recovery,
B: boot,
A: and-sec,
E: sd-ext (I don't need the external SD)
So there would seem to be no way to get modem and all the others I don't know much about anyhow.
When I tried to use the same command as above, I ended up with only boot and data - which is a great start! I think I saw an error that system was not mounted so maybe that explains its absence - perhaps I need to mount it first in my script (which I never have had to do on my Note 3)? Even though my V40 is rooted with Magisk, I am making changes to system so I do want to back that up (so long as I can use it during a restore).
Does it make sense to try and backup recovery since things seem really different recovery-wise on this device? Same question for cache and boot?
Thanks for your tolerance of my newbie questions.

Well from empirical experience, it seems that there is no way to backup anything save boot and data. I was able to mount /system_root but that had no impact on backing up system. And I was unable to mount cache or recovery explicitly so those are out as well.
PS - for anyone using the old 123 special partition for backups, they are no longer supported. I have never used them but decided to try and see what happened - only messages that they are no longer supported.
Perhaps there is some other way to accomplish this? Suggestions welcome. Thanks
Thanks.

That I'm aware of recovery should backup as part of the boot partition....I could be wrong tho

I guess that does make sense. Thanks. I am still trying to get my mind around the whole new situation (compared to my old Note 3).
