When trying to patch zip, app descends inside zip, it opens it, does not select it.

See screenshot.

Any idea how to proceed?

TIA.
[OnePlus 2 Android Development] nicesoni_ash:
Long press on the zip and then select open from top right.

Edit :

Or use a third party file manager.

[OnePlus 2 Android Development] piyushmodi01:
Ahhaaaaaaaaaaaa! Works Like Charm!

One thing I would like you all to keep in mind, do create a flashable ROM zip for primary one, in case you choose a BRICKED SECONDARY ROM, that flashable ROM will help you to select primary and get back onto it, otherwise you'll stuck in a bootloop and hence no option will be left but to go for a full wipe.
[OnePlus 2 Android Development] ketansharmar:
Can u tell in detail ??
[OnePlus 2 Android Development] piyushmodi01:
See this might happen, that the ROM you flash in secondary storage might be corrupt. So once you boot in your corrupt ROM, your device might stuck in BOOT LOOP and might not go into PRIMARY ROM.

So to overcome this, keep a flashable ZIP of your PRIMARY ROM in your storage so that you can flash it anytime you get into such boot loop situation.

This happened with me, and luckly I was having the ZIP in the storage otherwise complete wipe was only the option.

I hope this description might clear your doubt.
[OnePlus 2 Android Development] maerdance:
Just flash this:

https://dbp.noobdev.io/files/9.1.0.r80.gd5920b2/Utilities/DualBootUtilities-9.1.0.r80.gd5920b2.zip

and choose primary in MenÃ¼.

Much more convinient.

[OnePlus 2 Android Development] achuth20:
You can , Ive dual booted with Oos 3.5.6 and RR 5.8.0(Unofficial) with no problems.

And next time just search the thread man, I asked the same question just above your post
[OnePlus 2 Android Development] ketansharmar:
Should i install boot ui and from where i add another rom?
[OnePlus 2 Android Development] achuth20:
I didn't install boot ui, just watch a few tutorials on YouTube and you'll know how to use it better than I can explain it to you.

Plzz replay asap
[OnePlus 2 Android Development] chxei:
so here is the idea. we know that f2fs is faster than ext4, but if we format system to f2fs and install rom on system it converts back to ext4. but here is a trick, we can convert internal storage f2fs and install rom on internal storage(aka data partition) via dualboot and it won't convert to ext4, so whole rom will work on f2fs :)
[OnePlus 2 Android Development] vxkillswitchxv37:
I am running 7.1 as my primary ROM and 6.0 as my secondary ROM. My question is can I flash xposed on the 6.0 ROM and if so how would I do that? Do i need to patch the xposed zip so it will flash to the second rom on data slot? Any help would be appreciated. Thanks.
[OnePlus 2 Android Development] ketansharmar:
Yep u need to patch it and then flash as normal way
[OnePlus 2 Android Development] minhas729:
Can you explain how did you.

In my case, installation and booting of 7.1.1 ROM (AICP) on data partition is successful after setting up rom completely. when reboot is hit, it goes to bootloop

1. Did u chose your RR as secondary or on the data partition.

2. What code u assigned to data partition while patching files.

3. Did you change anything in file system?
[OnePlus 2 Android Development] achuth20:
1. Data partition

2. I used numbers

3. Nope ,didn't touch the file system

There :)

stuck on boot logo after flashing ak014 (patched) & ukm (patched) on Secondary rom resurrection remix (DATASlot)

could be related to dualboot error o incopatibilty kernel rom?

thanks in advance
[OnePlus 2 Android Development] mrsim:
if possible can anybody create a new step by step tutorial as the one in the OP is a little vague and does not push me in the correct direction to install this app...that would be awesome...i see no 'data' slot anywhere to add roms and also only have 0.22gb in internal and have no idea how to clear this in order to create enough space to install a secondary rom...also the OP ask's that i have to uninstall gmail and all gapps packages but these are part of the rom for oxygenOS so will i not be breaking the rom...am confused...:confused:
[OnePlus 2 Android Development] J_Dutch:
All the steps in OP are general instructions for all devices out there. OP also states you should use Data slot on our OP2. You can forget about all the other steps like cleaning system. You don't have to do that.

1. Download a ROM of your liking

2. From the Dual boot app, pick patch zip file

3. In this screen you pick One plus 2, second line pick data slot

4. Now the app will ask you to ID your slot, for example: exodusrom

5. Click to patch the file

6. Repeat step 2 to 5 for your gapps package, make sure the ID is exactly the same

7. Go to roms section in the app, tap the pink icon to add a rom, then click the +

8. Navigate to the patched zip file, created in the same location as your download and then choose 'keep location' (don't install yet)

9. Click the + button again for the patched gapps package and choose 'keep location'

10. Click the V in the top right corner to install the files, both in /data-slot-exodusrom

11. After flashing is done in ROM section tap on the installed ROM and reboot.

In case you want to flash a third, fourth, fifth, etc...:

1. Repeat step 1 to 3

2. On step 4, pick a new ID, for example: cm12

3. Repeat step 5, 7 and 8 (skip step 6)

4. Repeat step 9 except choose 'change location' to send it into the right slot, next you need to type the ID of your new slot, in this case: cm12

5. Repeat step 10, only now will both files flash into /data-slot-cm12

6. Repeat step 11

I for example have 4 roms installed without making space in any way and still have plenty of space left.
[OnePlus 2 Android Development] lukas77:
I deleted all google apps that can be downloaded from play store and installed CM12.1 as secondary on /system partition. It can be done.
[OnePlus 2 Android Development] J_Dutch:
Ok, but why take the hard way when there's an easy one too?;)
[OnePlus 2 Android Development] vergilbt:
Thanks for your explanation... But I got short questions...

Do I have to set ramDisk in settings?

Does multi-boy work at the moment only with cm rom? I'm not able to run hydrogen as secondary...
[OnePlus 2 Android Development] J_Dutch:
I have up to date ramdisk if that's what you mean, I have set it.

I don't know about hydrogen, but again don't run anything as secondary but as data slot. Did you try it in data slot?
[OnePlus 2 Android Development] lukas77:
If any ROM not working as second (data slot too) you may need to request support for this rom to the app developer, on his thread (link in OP).
[OnePlus 2 Android Development] alesfot73:
For update the space in the system? I have finish space.....

Just thought that I would say this is an awesome mod. It let me use Oxygen OS as my primary and Exodus as my secondary ROM because Viper4Android works on it. I will say however that when patching the files it did not work originally because it would open the ZIP file instead of trying to patch it but I did find that going though ES File Explorer fixed that problem.

[OnePlus 2 Android Development] VampireHeart:
No I have patched the open gapps mini with different ID for every Rom, because I think that flashing the same zip for every Rom make the same installation every in the same path.

For example if you patch open gapps mini for Temasek Rom in data slot with ID "temasek" and flash this file also for another Rom, you make the same installation of gapps over Temasek.

I hope can help you and what I say is correct.

I have used this method and deleted the patched file of gapps after installation and then patch the new gapps.

[OnePlus 2 Android Development] jaliscojorge:
If I understand this correctly everything to be flashed onto the data slot just needs to be patched with the same given name for the data slot? IE, supersu, blacked out apps, etc etc?

yes my friend, patch all zips you want on the given rom with the same. if you inadvertantly exit the patching menu before done, just write in the same name if it's not already in the drop down. i keep mine simple, primary, rom1, rom2, etc

you could have just asked me in H.O. :p

[OnePlus 2 Android Development] zoroarctic:
No, it doesn't

I tried using Oxygen OS and Cm12.1 with app sharing. It asked me to update my ramdisk to support app sharing. As soon as I did that, my phone refused to start. It went into a bootloop. Fortunately, I had a TWRP backup that I restored. Then I had to manually delete all the dualboot folders from the system because the app sharing locations had messed up all my obb files. So yeah, it was a pretty bad experience for me :silly:
