Hey guys,
Is it possible to use one of the roms and dual boot it with another rom with the boot manager? It says Galaxy S2 isn't supported.
Boot Manager Market Link: https://market.android.com/details?id=com.drx2.bootmanager
It says Galaxy S2 isn't supported.
Yes of course it is the developer is lying to you don't you think .

Haha good point! I know I started the application and it asked for so many things like what the sdcard block was and the system, data and cache size in mb was. So I thought might as well wait for someone else to try but where's the heroism in that
I am currently trying to get two independant, different ROMs to dualboot, but I am currently stuck at the 2nd OS not being able to fully initialize /data when booting up so the 2nd OS ends up in a loop at the bootanimation.

Ah! How much did you give for system, data and cache?
I "highjacked" the mostly unused partition 12 for the system, so it has 512MB, just like on the original system partition.
For /data I tried several things, one was a symlink into a subdir of the real data partition (that I mounted to another mountpoint) and the other was 100MB when I gave it the cache partition (mounted a tmpfs for /cache, so cache was still present and working).
Most files and folders in /data are created when the system boots up, but there is one point where it hangs....
It boots fine when I give it the original /data of the 1st system, but that defeats dualbooting IMO as I'd want to have a seperate set of data - and some ROMs need it as they are incompatible with the data of the other system....
Any progress on this?

Kinda.
Check the LolBoot link in my sig.
I worked around the /data init issue by not having it initialised at all, firstboot "native" and then copy the /data contents to it's new place.
That way the second OS is able to boot properly.
It's not perfect now, but works to a certain extend - of course I'm still looking for ways to make the compatibility better or other ways of dual-/multibooting....
But time's short ATM.
Also working on a small app that will aid in the process of setting up the dualboot as it is so far, i.e. no more need to mess around on shells, just tab some buttons and have it running eventually....
I have an S3 (i9300), and in recovery (TWRP 2.8.6.1) It will give me errors that it can't open folders in the data partition, so Aroma installer roms cannot format data, and I get a long error every time i data reset.
Data/misc/audit is unopenable (can't see it in file explorer in system, but i can see the folder in recovery)
Data/data/com.samsung.dcm - a folder in there is unopenable, is named as a tilted square with a "?"in ES.

For anyone still with this problem, the solution is to reformat and repair any faulty partitions in the advanced wipe menu in TWRP.
I am having this problem with an S3 that I'm trying to restore to stock. I can get TWRP on the phone but no image will install nor saved backups will restore. The reason is the data partition is corrupt. When I try using the Advanced Wipe option to repair the partition it reports:
/sbin/e2fsck -fp /dev/block/mmcblk0p15 process ended with ERROR: 4
Unable to repair Data.

Any other thoughts on how to repair the data partition? It was just working before trying to restore to stock, so I doubt it is a hardware problem.
For those facing the same problem. I did fix this but I can't tell you exactly what did it. I used the Terminal in TWRP to repair the partition manually. I think I used "e2fsck -cvf /dev/block/mmcblk0p15" and accepted all repairs. Be sure to say "no" to the first question that recommends you to stop. Then I used TWRP to format the partition and then it mounted just fine. I did many repairs on the partition using e2fsck and not all of them worked so I'm not 100% positive I know which options did it. I think it was "-cvf" but maybe "-B" also played a role. Either way, you gotta get that partition repaired before it will format and then mount.
Maybe flashing a stock ROM, with or without a pit file, would also work?

I tried that. That's what led to my /data partition being corrupted. I tried Kies 2.0 and stock ROMs with Odin. I couldn't get beyond the corrupt file system. I even got to the point where download mode was complaining to me about things being jacked. I thought I bricked the thing for a while.
Did you try flashing a stock ROM with Odin? Kies can't be used to flash a stock ROM unless you use the emergency recovery option.

Introduction
Hello all, this is my version of TWRP for the Nexus 6P, which includes the ability to convert your /data and /cache partitions to F2FS. This will stay inline with TWRP's changes for the most part, the changes will be listed below.
What in the world is F2FS?
From Wikipedia:
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 system that, 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.
F2FS was designed on a basis of a log-structured file system approach, which it adapted to newer forms of storage. Jaegeuk Kim, the principal F2FS author, has stated that it remedies some known issues of the older log-structured file systems, such as the snowball effect of wandering trees and high cleaning overhead. In addition, since a NAND-based storage device shows different characteristics according to its internal geometry or flash memory management scheme (such as the Flash Translation Layer or FTL), it supports various parameters not only for configuring on-disk layout, but also for selecting allocation and cleaning algorithms.

Before diving into this, I would recommend reading the official F2FS documentation to understand why this may be good for you. This is potentially unstable, F2FS is a file system that is very much in active development. There is a reason that most OEMs go with ext4 out of the box. But I digress, I am NOT here to sell you on F2FS; it makes zero difference to me if you use it or not, I am merely providing you with a tool to do so.
Changelog + differences
Differences:
f2fs-tools bumped to 1.7.0 (Omni's 6.0 branch is on 1.4.0)
TWRP app installation offer disabled by default
Conversion procedure
Download TWRP from the link above
Grab a kernel that supports F2FS (I use my own as I know it works)
Back up any important data as this will wipe your entire internal storage
Boot into the bootloader and flash the recovery
Boot into TWRP and go into Wipe > Advanced Wipe
Select Data and then hit "Change or Repair File System"
Hit Change File System
Choose F2FS and slide to confirm
Repeat the previous three steps for cache
Reboot and move all of your files back over (if restoring through TWRP, make sure to check the option to use rm -rf instead of formatting)
If you have any issues with this, you may need to ask your ROM developer to merge the two commits below.
Bug reports
You are NOT in ANY circumstance to report ANY bugs to the TWRP team.
If you have an issue with flashing something in TWRP, copy the recovery log to your sdcard and post it here.
If swapping to F2FS does not stick, try formatting your data with TWRP (Wipe > Format Data) or fastboot format userdata first.
If your phone does not boot after swapping to F2FS, either your kernel or ROM does not have proper support; post in their thread.
Additionally, check out some of these helpful posts:
https://forum.xda-developers.com/showthread.php?p=70699197
https://forum.xda-developers.com/showthread.php?p=71074016
Adding support to ROM
In order to properly support the initial conversion to F2FS, please add these two commits to your source:
https://github.com/omnirom/android_system_core/commit/1c6700a8fb31c6e314df4f031fa23fa9178c7ca7
https://github.com/omnirom/android_system_vold/commit/c879edb2fecae709f404c2d71c1d47ceac3a325e
The reason some people have issues converting is fs_mgr will try to read the block device as ext4 and destroy the f2fs block. This commit skips that check, allowing F2FS to pass through.
Sources
TWRP is licensed under GPLv3, meaning my changes must be disclosed. I also inline a custom kernel so that source is included as well. I also add in the other repos I modify.

First!
Thanks for the recovery. Been using it with flash kernel. I see considerable performance improvement in asphalt Xtreme game( idk if its the f2fs or kernel ).
Nice !!! :fingers-crossed::fingers-crossed::fingers-crossed::fingers-crossed::fingers-crossed:
Thank you, and thank you for the exemplary GPL compliance. It's noticed and appreciated.
Now this is awesome... On it, will report soon
Much appreciated!

Nitrogen should also work but i am doing something wrong... PN should only work with data to f2fs... i am trying different ways right now.
I restored everything to ext4 but i get bootloops now with everyrom... reboots constand... damnit
restored my twrp to latest 3.0.3 but i still get bootlooping... whay did i wrong :S Going back to complete stock latest google image... can anoyone tell me what i did wrong here?!
Restoring factory worked... back on 3.0.3 twrp and with PN rom installed. I will wait a couple of days on how to get it working properly on PN
Worked perfect! Thanks Flash!!!
I tried this with PN and am now stuck in a boot loop. I flashed the twrp with F2FS support then tried to change the file system followed by installing the latest vendor, latest flashable bootloader+radio, latest pure nexus and gapps, flash kernel, and latest su. Didnt work. Im not stuck in a boot loop I cant get out of. Ive tried every combination of the above. I also tried restoring my backup but that gives me an error. I also tried changing the file system back to ext4. Nothing works. Anyone experience this or have any suggestions?

Data keeps reverting back to ext4 after 1st boot.

Mine too....Im stuck in a bootloop. Are you?
Whats also weird is switching too f2fs wiped my storage but once the data reverted back to ext4....my original storage came back too!! Im not sure how or why that is happening either.
I just followed OP and formatted everything first, now i have SAOSP running with flash on f2fs..
Works great, so far it doesn't feel like a huge improvement though..

What makes you say that?
Back then when I was using Temasek on my Note 3, he incorporate a script that automatically format the system partition to F2FS when flashing his ROM. That is if the system partition is already in f2fs and I think that was pretty amazing but short live. I wonder if other ROM developer could go the same route if formatting F2FS system was popular enough. That would make updating new rom one step easier. Just for thought.

Hi All,
Make sure to restore your backup with "Use rm -rf instead of formating"; else the restore will reformat the partition back to the file system use in the backup.

Because that's what's happening to me. Maybe it's because I'm on PN. At this time f2fs has not been widely adopted by too many devs so compatibility could be an issue. I think I'll stick with ext4 a bit until f2fs is fully mature.

That's too bad its not working for you, its working on my side no problem, did you format in twrp if its not sticking? Im on RR with Flash kernel.
When I try to format my Data partition to F2FS it shows:
mkfs.f2fs -t 0 -r 16384 /dev/block/sda9 process ended with ERROR: 1
Unable to wipe Data.
Error changing file system.
And also when I format System to F2FS it succeeds but when I install a ROM (AOSiP) it won't install unless I reformat it back to ext4.
Hope anyone can help..
Thank you!
Heyyo, pretty much all ROMs will force system to default to ext4 for compatibility and stability reasons.
With that said? It is still possible to run any ROM that has f2fs support with your system as f2fs but you gotta work for it.
1. Install ROM (with gapps, etc)
2. Make a backup of system
3. Convert system to f2fs
4. In TWRP settings, enable the "instead of format use RM -rf"
5. Restore the backup of system
System should now be in f2fs... Albeit I can't remember if future ROM updates will revert to ext4 haven't tried system as f2fs in a long time...
As for data? Please flash the GalaticStryder build of TWRP found in my TWRP thread. It's a bug on TWRP for the make.f2fs not having the necessary updates for the encryption footer thus that encryption length error message.
Once you flash GS TWRP build? You should be good to go for converting data to f2fs.

Hi! I know it's been so long since I posted this but when I flashed AOSPExtended it shows an "Encryption unsuccessful " screen for me whenever I format Data partition as F2FS :/
Update: Dirty Flashed latest AOSPExtended and made a backup of it, did what you instructed and when I boot the phone it goes to fastboot mode.

Hi friend, does Lineage run well with the system partition in f2fs?
I use only the data, do you think it's worth the test?
Rom is great at it, congratulations! :good::good:

Heyyo, hmm if that is the case I think AOSPExtended doesn't support quota for storage.. the only way to resolve this is to backup your data, copy it to USB OTG or to a PC and then going to wipe > format data > yes. After that you can copy back your data and restore the data backup.

Heyyo! To be honest I have not tested it much with f2fs. It feels smooth enough but then again ext4 still runs pretty darn good so any performance improvement is minor.
I only ever recommend converting the cache partition to f2fs as it constantly changes data and f2fs still doesn't handle file system fragmentation as well as others such as ext4 so f2fs on system and data still isn't as ideal as ext4 for long term performance retention.

f2fs ist superior to ext4 especially in write operations. That's way if you use f2fs you don't be affected to the slowness who comes with the time with the ext4. Otherwise ext4 exist longer and is more, lot of people assume this, stable. I use f2fs long enough to say that my last freezes with the f2fs filesystem are way back to 2014. Even then I would say that the troubles come with the custom roms than with the f2fs.
I use in my x2 the Lineage unofficial with f2fs without a single performance degradation and before that used Infrag nougat aicp with f2fs. F2fs is better but lot of people have trouble or they don't know how to convert the /data partition and before that that they must Backup the /internal Sdcard as the convert process wipe the whole /data + /internalsd
Here more Infos why f2fs is the better filesystem

Hi together,
i have an problem with the tablet encryption.
i wanna swap from xiaomi.eu to another more actual custom rom..
i tried PixelExperience , Havoc-OS, dotOS, ArrowOs .. and everytime i activate the encryption it's end in an bootloop regardless of pin,password,pattern ..
I'm using the latest TWRP Version
- Wipe Dalvik/ART Cache, Cache, System, Vendor, Data
- Flash from zip
- start os and enable encryption
-> bootloop
My experience with this device is limited, but I faced a similar problem switching from stock rom to an older ROM not using any encryption.
I think it was only succesful after removing encryption. Maybe it also helps in your case?!
There are many guides how to remove encryption, most of them suggest "Advanced Swipe" combined with changing the file system.
I used TWRP to swipe "data" to ext2, then again swipe "data" back to ext4 and afterwards it still needed a tap on "File System Repair" for the "system" partition. After that, the flash and boot worked for that older ROM.
Maybe that will leave you with a better starting point for activating encryption of your ROM.
(But as I wrote: Just a guess, not based on experience.)

Hi,
thanks for your answer. As i wrote i delete nearly everything
The OS booted, but at the point where i want to enable encryption most roms get stuck in a bootloop.
After endless roms i found carbonrom which works.. Additionally i found an post from TWRP about encryption.. i don't know if it's connected, but i guess it's an similar problem cause AOSP..
Why doesn't TWRP support encryption on my device?

twrp.me
So i found a working rom, but not the solution or true cause of the bootloop problem
Ok, I understand.
I guess I don't know the encryption feature well enough to help.
Found some interesting stuff to read about it, not sure if it applies to the Mi Pad 4 and its custom ROMs, though:
Any way to encrypt /data/data and /sdcard on Xiaomi EU ROM?
Hello, Xiaomi EU ROM is running decrypted, that's a security breach... Is there a way to use Xiaomi EU ROM, based on Miui 10, in a encrypted phone? Thanks
forum.xda-developers.com
So the bootloop seems to be expected and if I got it right then the fstab.qcom needs an edit at least.
Mhm it's confusing me.. cause i run nearly 5 years xiaomi.eu rom encrypted from scratch on. i think with FDE .. the rom says encrypted and twrp says encrypted and the sdcard folder is only crypted filenames.. also interesting the article.. but i'm sceptical that edit the fstab.qcom maybe work on more "normal" AOSP roms..
so i found a working rom i'm not motivated enough to try the edit xD

Yes, sorry, I fully understand your point of view.
It is confusing me as well.
I'm currently experimenting with some ROM's, so yesterday I gave encryption on Havoc-OS a try - even by starting with encrypted stock rom, flashing Havoc-OS and modifying fstab.qcom - but without success. It rebooted immediately and then seemed to be hanging idle during boot for a long time.
I was not interested in encryption so far, but of course it would be great if it worked. And I should be interested for the sake of privacy.
Thanks for reporting that it works with the carbon ROM.
Edit: In Lineage OS it will probably work too, based on the description of the ROM.
I will probably try that one next, because it is also supposed to have the "split screen" feature which I am looking for.
Encryption in Lineage OS seems to work fine, as expected.
I tried to analyze Havoc OS encryption once more: It seems not to be supported at all.
It does "something" trying to encrypt... because TWRP asked for a password the next time I rebooted to recovery. Problem is, decryption in TWRP did not work with the previously given password and the data partition seemed to be messed up (file system type was "emmc", and the data partition was not responding to any of tune2fs, e2fsck or alike).
I looked at the dmesg log, it seems during the boot attempt, the system just cannot work with data any more (hence the idle hang, I assume).
There are many many log lines, showing attempts to work with data and that the system actually expects an ext4 file system for "userdata" (=mmcblk0p64):
Code:
[ 2.990548] EXT4-fs (mmcblk0p64): VFS: Can't find ext4 filesystem
[ 2.990698] EXT4-fs (mmcblk0p64): VFS: Can't find ext4 filesystem
