Can I just copy /data/multiboot/data-slot-x/* to /sdcard/data, wipe data and copy from sdcard to /data to use the data-slot-x rom's data for the same rom flashed as primary? If not how can I recover my data if I want to go back to having one rom?

Specifically, what about file owners and permission? Are they retained on the /sdcard?

I did what I described above, booted into the ROM, it worked, but when I upgraded from LOS 14.1 to 15.1, ROM didn't want to boot although dirty flashing should work according to developers.
[Galaxy S 4 i9505 Original Android Development] Eleo:
If you want to directly move data from one rom to another, then I am assuming both these roms are of same origin and same version (if not, then dont do it). If that is the case, then boot to data slot x, open dualboot patcher, backup data slot x (the slot that you are in) and restore to primary. Just for caution, backup primary too (in case you mess it up by restoring).

If they are not of same version and same origin, then Titabium Backup (or swift backup, super backup, my backup and other similar apps that backup and restore apps and data) should work. Just dont restore data of system apps if you are doing it cross-platform (other rom versions/ origins/ android versions).

Good luck.

How to update DBP?

Hi,

I have the DBP 9.2.0-DEBUG version (The first one released for the s8+) installed on my galacy s8+.

However, this build seems to be pretty old now and I would like to update it to a newer build.

Does anyone know how I should do this? I believe I've already tried it once and it caused my roms to not boot anymore..

Thanks in advance!

Just saw the rest of your message... I don't know. I suppose I'm more confused than I thought. I believed Qualcomm to be a USA based program integrated into Snapdragon.

the patching and flashing processes are all good but after rebooting, it gets stuck at the Google bootlogo for a while and reboots to recovery

does it has to do something with magisk as it only supports lollipop<

Okay first, to yayakuya, I think I had the same problem. I'm sure you figured it out by now, but just in case, you're clicking the large box with the zip icon in it. Try clicking the tiny icon in the lower left of the box, just to the left of the zip title listed at the bottom. That should select the file instead of opening it up.

Now for my own problems.... Trying to attatch two files (let me know if they don't load, keep trying but for some reason things go south on me), one is the multiboot log and the other a picture of my screen. I have tried flashing both in app and through TWRP. In app gives me error code 1 (see screen pic) and TWRP gives me zip verification error. Disabling zip verification gives another error but forgot what it was. I made several patched zips, to install both to secondary and to extsd labeled rom3, rom4, & rom5. Rom2 would be secondary and of course rom1 would be my primary. My primary is currently Tesla ROM with Android 7.1.2, kernal version 3.10.49+ hercules. Dual boot versions I have are 9.3.0.r806 & 9.2.0. My phone is an Asus Zenfone Selfie Z00UD, part of the Z00T family. SD card (external) still has plenty of room on it. Internal memory is currently down to 3 to 3.5G, hence trying to install to external SD. Any ideas anyone? If I left out any info, please let me know & I'll try to post it.

Thank you for your time & help! Very excited about this, was waiting for something like this ever since I had SafeStrap on my old Motorola! Thank you!

PS. Okay, still don't think anything is uploading. I clicked on advanced, then attachments and selected my pic (2.9MB) and the log file (48.9kB) and tried uploading together and separately but... Maybe a network problem on my end? I will try later but for now I will post this, it's been sitting on my computer now for several days! Oh wait, maybe they are finally there now.... Woohooo!!!

I am curious whether it is possible to install a second rom without root installed on that rom?

I have a pesky banking app that isn't fooled by any of the magisk techniques.

Well yes, that's true but it resides in a ROM's boot.img. Usually one is trying to get a particular ROM to work and the kernel, ramdisk, what have you is in the boot image.

On other slots it doesnt interfere. But even if it is in system (i.e. secondary slot) it does not interefere with safetynet of primary slot.

And yes. No matter in which slot you are, other slots (other than primary) cannot pass safetynet. So you will have only one slot that can pass safetynet.

If I'm not mistaken one still needs a patched version of Magisk (not the same as just patching it with DBP). Last patched version I had was v15.3 I think. Even then I don't think installing modules was working. I only use SuperSU on the ROMs so not sure of the latest DBP+Magisk status.

Anyway, maybe you should've searched the thread for Magisk first.
