    Question How to PreRunning preloading pretesting custom/stock ROM in android virtual machine on mobile device


    I Have many custom android custom rom (android 6,7,8,9,10,11) availabale for my device i want to check all roms and test their features (mainly adoptable storage or move app to sd and permission security features) and weather it's not a buggy or problematic rom before installing or flashing is there any app available which can load the android on virtual machine virtual box or android emulator on mobile device (not on pc computer)

    After google I founded a link quesion in the forum and answered by ash-ish which link and aswer I pasted below stating how to virtually load the custom rom through multi ROM app

    Before trying I just want to confirm and have following queries in mind


    MY queries

    Q1. Is multiboot app install multiple roms or single rom

    Q2. Does multiboot app safe and authenticated

    Q3. Does multiboot app really load virtually the custom ROM or it writes or install roms to the internal memory or does it touches any rom partitions

    Q4 does chances to brick the mobile if there is some buggy or corrupt custom rom image then can I corrupt the original firmware of mobile device while loading virtually

    Q5. Can later multiboot app be uninstalled and remove do it leave any leftovers in rom.. if I take NANDROID backup of recovery system userdata and boot partition through twrp ir adb pull can I r cover back the mobile or recover from bricked stage of mobile device


    Q6. As the suggestion in the following link answer for multiboot is for samsung galaxy edge will it work on all android mobile will it work on my lyf water 7 device


    Q7. Any more advice opinion suggestion expert advice

    You will need to have a rooted phone with a custom recovery (most likely TWRP) installed. The Multiboot app page on stackexchange seems to be clear enough, remember that you will need ROMs specific to your EXACT device (There can be several versions of a device using differing hardware intended for different markets around the world). Just be sure to fully understand the steps and files required.
    I'd install the custom recovery and root the phone first so * could make a nandroid backup (A full backup of the phone including the Operating system so you can recover the phone to it's previous state if anything goes wrong.

    @Davdi bro thanks for sharing your precious time advice opinion suggestion and knowledge to greatful for you thanks a lot

    @Davdi bro how much internal memory free space is needed for multiboot app to work virtually load the custom rom (can we check how much space rom requires before virtually loading or installing as no information given on custom rom features page) do multiboot app it is compatible with all android os versions (5.11 or 6.1) or with specific android versions or its work for only some specific mobile devices or all devices.

    Yes I have loaded twrp recovery through fastboot boot twrprecovery.img (loading twrp recovery in fastboot bootloader mode) and succesfully taken NANDROID backup of system.img data.img boot.img backup through twrp recovery in backup menu (without rooting) and also with adb pull .../mmcblck0p30 system.img also.

    but I am confused that if something goes wrong then can in recover the backup write flash back to the device rom (if something goes wrong) from the fastboot bootloader mode loaded twrp recovery image (fastboot boot twrprecovery.img) or I should install flash write the twrprecovery.img to the recovery partion to (as I prefer not to touch rom till nothing goes bad) but still I have to root it anyhow for multiboot (magisk superuser)

    Amount of memory and storage depends on the ROMs you want to use. Ideally you'd want enough storage to install multiboot and the other ROM you want, leaving enough free storage for everything else you want on the phone. If the phone came with Android earlier than 6, you'd be struggling with storage. As for memory (Ram), if the ROM is specific tou your phone, there should be no problem. Have a look at xda-developers.com for your phone to see what ROMs may be available.

    ocnbrze DON'T PANIC!!!!!!!!!

    Yeah this phone really has no dev community. It's almost pointless to discuss other roms as there is only a handful of them out there.

    Really I think you just need to find a better phone that has more ram and storage space. Or at least a phone that has a better dev community.

    Yeh they're hosted on OneDrive with restricted access. If the dev isn't responding to access requests. They were posted 4 years ago, and maybe the original dev is no longer around? Given that, I think the only thing you can do is to join XDA, make a post in that thread, and hopefully someone else has those ROMs.

    16GB is going to be very restrictive even with just one ROM. The one phone I had with only 16GB, was my original Samsung Galaxy S, I had ten years ago.

    No idea, I didn't even know that existed until I read this thread.
    Somebody else may know

    Of course I can't tell you if any of those Lyf Water 7 ROMs are any good, or safe, or not, apart from reading what's already posted in XDA.
