[Galaxy S 4 i9505 Original Android Development] Eleo:
Depends on too many factors. Lately I found out that old vrtheme engine containing aroma installers dont work with multiboot. So no comment on why you couldnt boot. Also, patched kernels have bigger size than unpatched; if upon patching its size exceeds limit for boot.img of your device it also can lead to not booting. That time you need to change kernel to a working one.

And many many more factors can affect

Is lg v10 h901 supported?
[Galaxy S 4 i9505 Original Android Development] Eleo:
Go to supported devoces and look for your device in list. If it is present, install and use app. If your phone is not on supported devices list and you want to support your device, flash the GetLogs zip from https://dbp.noobdev.io/downloads/ and share the tarball it creates in /sdcard/logs/ (file extension is tar.gz) in a post with description of your phone model. After that, you can either wait for users or dev to add your device to supported list, or add your device yourself.

To add support for your device, do as explained here. Before it is officially supported, you can compile unofficial apk with your device support and use it. Once it is approved by dev you would see your phone supported in changelogs on dbp.noobdev.io/downloads page. Then you can download and use the official app.

I hope it is clear.

Cheers:)

All of a sudden when I install a secondary ROM it always boots to recovery when I try and switch to it, I have installed dozens of ROMS to the secondary and data slots and have not changed anything to my knowledge. Has anyone ran into that happening. I am using version 9.2.0_r92 for the duall boot patcher app and i use the dual boot utility zip to switch the ROMS. I don't get any error messages to tell anyone so I'm not sure what to do. I am trying to install SAC23 S80 Port as the second and have echo Pure ROM as the main, I have update ramdisk and set kernel on primary

Flash ROM again, try booting. If you cant, switch ROM and share the mutiboot.log in internal memory. The clue should be in that log file.

The attached file helps you creating .yml file for your device.

Just go to TWRP and then INSTALL it, your yaml file will save to /sdcard/ directory. File name gets from ro.product.manufacturer and extension is .yml.

If not, default name is device.yml.

You can get help using Terminal as follows:

cd /tmp/genyaml

./genyaml -h

Can someone please tell me what Boot UI is for and how to use it?
[Galaxy S 4 i9505 Original Android Development] aadi50:
It provides a boot time ui screen at just before bootlogo... that provides option to switch roms .

It appears everytime you reboot your phone with default 5sec delay counting down to 0... with two buttons below

EITHER to skip delay and boot directly OR press CANCEL button to switch roms in next screen...
[Galaxy S 4 i9505 Original Android Development] edyny1:
Which two button below or cancel button? I have galaxy s7 edge

I meant, there will be buttons in the Boot UI screen, which will appear when you will reboot your phone...

In your screenshot, it is just settings to enable/install it.

In your case, its showing "up to date" ... It means its enabled... Just reboot to see Boot UI.

Hi,

I am using DBP for some time now, even app-sharing feature (which I find extremely useful, btw). Everything worked flawlessly with DBP versions before 9.2.0.

After fresh installation of primary ROM (everything was wiped in TWRP before installation) I installed latest DBP (9.2.0.r167.ge5f5094), but it refuse to update ramdisk (log attached).

After trying to resolve problem for some time, I accidentally installed old version of DBP (9.1.0.r243.g9ea941e2) and everything went fine (ramdisk updated normally).

Both, unsuccessful update (with new version) and successful one (with old version) are covered with log file, in that order.

Right now I am using old version of DBP since everything work as before. I am aware that newer version would probably work also, since ramdisk is already updated with old version, but I did not tried it jet.

Primary ROM is Lenovo VibeUI 1631 MM on Lenovo K3 Note device.

If anyone can help how to resolve an issue, I would be very grateful

Thx anyway mate ;)
[Galaxy S 4 i9505 Original Android Development] gaww:
I never had problems with that ROM as primary. Could it be related to the kernel ?

Can you add a device identity override for your built in Rom flasher?

Basically I have a number of Canadian devices (note3,s4,s5,etc) and while the devices are basically the same as international variants the name has can added to the end (hltecan vs hlte, kltecan vs klte)

And while I can usually use the international recovery to flash (it thinks it's hlte not hltecan) your built in flasher errors out telling me the Rom is incompatible ( the install script in the Rom checks)

And since almost no one who creates international roms specifies its compatible with the Canadian variant I have to either ask every developer to specifically add the Canadian variant or never use your built in patcher.

Thanks

[Galaxy S 4 i9505 Original Android Development] Eleo:
I already provided procedure to "how to app share in DBP" repeatedly. Please search in thread before posting.

Not unpatched ROM. ROM zip should be patched. Flashing unpatched ROM will most probably wipe other slots data or ROM itself. ROM zip should be patched. But other zips flashed to primary can be unpatched.

[Galaxy S 4 i9505 Original Android Development] gaww:
It will only wipe secondary ROM, which is the only other thing in the /system partition. reflash it and data is still there.

I am always doing this currently, as flashing Echoe patched as primary never works for some reason. After flashing, I set kernel to primary.
[Galaxy S 4 i9505 Original Android Development] Eleo:
I once flashed unpatched ROM... that caused too many issues. Had to remove dualboot, flash stock ROM and then start again from point zero.

I cant flash ROM in secondary, since /system space in note3 is 2.3GB which can only hold one TW and 1.5 AOSP ROM

:D

Dont know what was the problem that time, but repeating same steps instead of flashing unpatched ROM worked very well. Other zips to primary I flash unpatched.

P.S. The time for "copying file to system" for flashing primary patched ROM has decreased a lot than it was in earlier versions, so I dont mind flashing patched ROM to primary.

P.P.S. Have you tried to investigate why flashing patched Echoe ROM is failing? Any logs or info about that? Would like to diagnose it if you dont mind... seems interesting. Maybe some edify script not compatible with multiboot? Does it work when flashed to any other slot?

And in my opinion it should work on any phone

Untill and unless htc has done something with boot.img

U can always give a try to a universal dualboot

Which will work on any phone

By just editing fstab.qcom in boot.img

So that it will load files from different partitions

I probably misread thinking it would make the script on the Rom think the device is hlte not just the dualbooter.
[Galaxy S 4 i9505 Original Android Development] KaMyKaSii:
If you are sure that the rom in question works on your device (although it does not seem like it, since several other codenames are present except for yours) you can extract the updater-script, open it with some text editor (I like QuickEdit app) and remove one of the starting lines that starts with "assert", save and add updater-script on the zip again. Thus TWRP will not check the device at the time of installation. It is quite obvious but I will say just in case: if the rom in question was not made to work on your device, you will have problems. But considering that you are not installing over some already functional ROM on your device, if the new rom does not work, you should go back to TWRP, go to Install, /sdcard/Multiboot/some-rom-that-works, click "Install image" , select boot.img, install on the Boot partition, and then restart.

How install gapps in second rom..=????

Tks...!!!
[Galaxy S 4 i9505 Original Android Development] wingg:
You have to patch it or obtain patched gapps.

How to patch "gapps" -> jest put boot.img (it's a kernel file extracted from a cwm ROM ZIP file) into a gapps cwm ZIP file. Trick is that Dualboot.apk "recognise" gapps as a ROM & patches it.... after that just remove boot.img from patched gapps.(use x-plore.apk -file explorer from market -it can handle .zip files without loss).I've tested pa_gapps-modular-mini-4.4-20131126-signed.zip and successfully patched & installed.
