Hello.. I m using dual boot patcher in My 3S.. I have installed Resurrection nougat as my Secondary rom for some work Purpose and cr droid oreo As primary. Its all working fine..no issue at all.. But as i have 16GB variant.. My device Running out of Storage after installed 2 Roms.. I have a sd card of 32GB and also having an OtG pendrive of 32GB.. Is there any way to flash the secondary rom in the storage of Sd card or otg ( whenever i want to boot to the other rom. I can Insert otg).. Or atleast install on SD CARD??? i couldn't find such way in google search or in thread.. If there is anyway to do that.. Please guide me.. As i really want a secondary rom. But there is storage issue..
[Galaxy S 4 i9505 Original Android Development] Eleo:
Just use "extsd slot" for ROM in "sd card". No need to google search as it is already mentioned in thread.

In android, "sd card" is actually internal memory of device. "External sd card" is the slot that you want to fill. OTG is not possible since drive speed would be slow.
[Galaxy S 4 i9505 Original Android Development] Bhabesh98:
Thanks.. But tell me one thing more.. As i have already installed the Secondary rom.. And using it... Anyway there to Just change the path of that rom from my sd card to ExtSD card? As a result the rom files will be moved to my ext sd card without wiping anything

Of course. Answered in details on my previous post (with attachments):

Backup your external slot (choose backup location as external sd card in app settings since you say you dont have free space in internal). Then restore the backed up slot to external sd slot (shown on post that I linked above). Then you can remove your backup and use slot as external sd slot.

Please search before posting. All info is already present in thread. Searching will reveal you more answers and faster.

Not useful. We need logs to troubleshoot. Logs are in internal/multiboot/logs folder. If you have a bug to report, provide info and logs in github, link shared in OP.

Read posts in thread. Either dont use oreo or dont update ramdisk. Those are your options.

So you need to grant write access to extsd card for DBP.

[Galaxy S 4 i9505 Original Android Development] Eleo:
Ask in your phone forum in XDA. I dont know the way for all devices because I cant know it. Search "how to grant write access to external sd card in <insert your phone model here>" or read your phone forum and you will get the answer.
[Galaxy S 4 i9505 Original Android Development] marcdw:
Maybe select a subdirectory also (for instance /Multiboot/backups/ or whatever you create beforehand). Just to see if that matters. At the moment you have the backup directory set to the root of the SD card.

The backup creates a lot of files that you definitely wouldn't want piled up there anyway if it did work.

How to install Xposed In Secondary rom? Help me

I tried

1 - Flash through magisk.. Failed

2- flash through recovery. Failed ( as my Primary rom is Oreo.. And secondary is nougat.. Recovery showing Wrong zip file version.. Means Its taking the zip file for My primary rom)

3- patched the xposed zip file through Dual boot patcher app.. And tried in app flashing.. Failed too

4- tried flashing the patched zip file through recovery.. Same.. Failed.. As in app flashing showed

Here is the log file generated from in app flashing for above xposed flashing issue (My previous post)

Sorry for the above two post of uploaded log file.. I was trying to post it.. But it was not showing it posted. Even after refreshing.. So i uploaded it 3 times without knowing its posting.. And after restart the xda app.. I saw its posted 3 times.. Ooops.. Never mind.. Clean the thread if possible :)
[Galaxy S 4 i9505 Original Android Development] Eleo:
For that one we need "multiboot.log". It is generated in root folder (not the one that requires root access, but the first folder that is opened with file explorers) of your internal memory (sdcard/). If you check your attachment on this post, you will understand what I mean (the line which says "the log file was saved as multiboot.log in your internal memory)

By the way, as I remember, magisk modules are not working on dualboot, i.e. even if you successfully flash xposed systemless into your "non"primary" slot, it will still not work. You need to have system xposed zip flashed after patching in dualboot app. Only that way you can have xposed in your "non-primary" slot.
[Galaxy S 4 i9505 Original Android Development] Bhabesh98:
Let me try system xposed instead of System less :laugh: i ll reply soon
[Galaxy S 4 i9505 Original Android Development] Bhabesh98:
I tried the system xposed flash through recovery.. After Patching through app.. But sadly when i tried rebooting device.. My device vibrated 5times..then Opened twrp.. I tried dbp utilities zip.. And tried switching to primary rom.. No luck.. Tried wiping the secondary rom.. (in which slot i flashed Xposed).. No luck.. Tried Deleting the multiboot folder through aroma file manger.. All the tries gave me only that 5 times vibrate and opened recovery.. Then there was only way.. I WIPED all the things :crying: .. Then installed a new rom... And my phone is now usable.. I didn't expected this.. I ll need to Wipe everything without backing up data:rolleyes:
[Galaxy S 4 i9505 Original Android Development] Eleo:
I cannot troubleshoot without logs. It failed to boot somehow but I dont (and cant) know why. That should happen if kernel (boot.img) has some kind of incompatibility with your bootloader. But I have used system xposed on dataslot (non-primary) with no issue.

I really cannot troubleshoot and understand why it failed on you.

About backing up... yes. You should have done it before going experimental. I am sorry for your loss.

LG V10 support

How do I go about request support for the T-Mobile LG V10 (H901) (The AT&T Version is the H900 and the Verizon version is the vs990 I believe) which is going to be similar to the LG G5 and the LG V20? The different versions will probably still have the same file paths.

One difference for the V10 vs the LG G5 and V20 is this path: /dev/block/platform/soc.0/f9824900.sdhci which appears to be unique. Is there a program I can run which will collect the information you need? It has support for a fairly large external microsd card as well as 64GB internal storage so seems to be a good candidate for running "dual os".

You can refer to this website: https://github.com/chenxiaolong/DualBootPatcher/issues/845#issuecomment-372010564 ,it tends to modify the boot image.

I have a Oneplus2, and my secondary ROM(data slot) is Oreo. My way is simple and rude: I abadoned the primary ROM; Then in TWRP, I flashed an Oreo(not patched), then flash patched Oreo, then flash things to /system, then backup /system partition,then reboot the phone. Every time I switch Oreos, I restore the relavent system backup in TWRP. Of cause, this way is not recommanded and is buggy(camera/sensors are down, sometimes the secondary Oreos do not boot and need a force reboot ). I do this because I‘ve found the secondary Oreos always boot from the primary system partition on my phone.
[Galaxy S 4 i9505 Original Android Development] cubandanger05:

Is it as simple as adding a device's codename to a new build? or is there more to it? Does it have to do with the ROM as well?

I know of someone using the N910V & N910F, and DualBooting seems to be working great on their part.

Newer builds of the DualBootPatcher crash on my Note 4 as soon as I click on the "ROMS" section, and older builds hang on the "set kernel" part.
[Galaxy S 4 i9505 Original Android Development] marcdw:
You can take Magisk and patch it in DBP but it will not work.

You need a Magisk that has been modified to work with DBP.

I have one modded Magisk v15.3 that by default is for primary. When I first got it I patched it with DBP for a data slot. It failed to flash. I later realized what I was supposed to do was extract it, edit a file where the destination is defined (multiboot/info.prop), and rezip. Then just flash it.

So I made multiple copies to accommodate different slots.

But no, you can't just patch Magisk in DBP.

So, I did not have this app before flashing my primary rom (WizCyan v4.1) on S4 GT-I9505.

Installed this app later.

Then, I patched the secondary rom(LineAge OS 15.1 here ) (chose ext Sd card partition) using DualBootPatcher.exe

Copied this file to SD Card. Then Flashed it using In-App Flashing. It was flashed successfully. But "Failed to Switch ROM" every time I try to boot it.

So, I deleted it from Ext SD. Then Booted into recovery and tried to flash that patched zip file.

It terminated saying. This ROM is for jflte,blah blah, your device is.

Yes, It ends on "dot".

My build.prop file is attached. I tried to replace every zerolte with jflte. But No Success. View attachment build.prop.txt

So, As a Last try, I tried to patch my Primary ROM's zip. and got the error. (Attached: View attachment 4489491 )

Note: The LineAge OS 15.1 is not like other Flashable zips. i.e. it does not have /system/app or priv/app folders. I could only find system.img useful.

[MENTION=7285395]zubair1836[/MENTION], it's been said many times in this thread that Oreo as a secondary doesn't work. Should've searched first before trying.

Oreo ROMs can be used as secondaries if properly prepared. For instance I'm running AospExtended 5.4 Oreo on my Axon 7 as a secondary because someone provided patched kernels for use with DualBoot Patcher.

Folks have other methods I've seen but in general it's a no-go.

Thanks for guidance. But, That was not my only problem. I want to flash LOS 15.1 as Primary and "WizCyan v4.1" as secondary. But I can't patch its zip. Error Attached with previous post.

One more thing. Is my

build.prop

fine? (Installation terminated because device not supported)
[Galaxy S 4 i9505 Original Android Development] marcdw:
Okay, I'm kind of confused.

For LOS, the ROM is for zerolte but you edited its build.prop to specify another device? Nah, that wouldn't work. Device is also specified in the updater script which is used when flashing.

What I usually have to do on my Axon is unpack the ROM, edit META-INF/com/google/android/updater-script, remove the assert line(s) at the top, then repack. ROMs would then be patched and flashed as secondaries (not Oreo though).

For your Lollipop ROM I figure you could try that.

I do everything on the phone. If you edit that file on Windows just make sure to use an editor that preserves the line endings.

The build.prop attached, if it's the original, is fine.

The Axon 7 is the only phone using DBP and it only has Nougat ROMs plus the one Oreo. Haven't seen Lollipop mentioned much here lately.

Let me clear what I want to acheive. 1. I want to flash LOS 15.1 as primary. 2. Flash WizCyan v4.1 as secondary (tried to patch it but failed without any erro).

Sorry, I don't see any assert written in updater (in wizCyan v4.1), Attached: View attachment updater-script.txt

Regarding the assert lines, removing that is necessary on the Axon 7. Not a requirement on the myriad devices DBP supports unless stated otherwise.

Sorry I couldn't be more helpful.

BTW, is MultiROM available for your device? If so you might want to give that a try if all else fails.

[Galaxy S 4 i9505 Original Android Development] marcdw:
Patching has never been required with MultiROM. The only requirement (in the past) is that the primary ROM use a kernel with the kexec patch. That doesn't seem to be a requirement anymore.

Basically it was...

Flash MultiROM-TWRP. Reboot back into it.

Flash MultiROM. Set it up. Particularly the no-kexec workaround.

The MultiROM Manager app is best used just for quickly switching/booting ROMs. I've never used it to download or install anything. My devices aren't officially supported for that anyway.

Good luck to you and if everything works out, happy multibooting. ??
