Hi all, I have a few questions concerning the nexus 7 flo.

I have unlocked, flashed twrp, rooted, and backed up my tablet. Now I want to flash other ROMs and Linux.
My questions are:

1. Do I need to remove twrp to install/flash multirom?
2. Will the stock kernel work with multirom?

Thanks for your help!

1. No. But you will need to reflash the recovery with the supplied modified recovery(.img)-file. This will overwrite your previously installed recovery with a modified version.
2. It will not work: you need to have a kernel that has been patched with the kexec-hardboot patch (I use ElementalX)

Note 1: Your device must not be encrypted (hint: if you don't know what it is, then it is not encrypted).

MultiROM has 3 parts you need to install:
MultiROM (multirom-YYYYMMDD-vXX-flo.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_flo_YYYYMMDD.img) - download the IMG file from second post and use fastboot or Flashify app to flash it.
Patched kernel - You can use either one of the stock ones in second post or third-party kernels which include the patch, you can see list in the second post. Download the ZIP file and flash it in recovery.
You current rom will not be erased by the installation.
Download links are in the second post.
MultiROM is compatible with both flo and deb.

Thanks! Also, do you know if it is possible to compile a kernel for flo with the rtl8187 USB drivers included, or if anyone already has.

Hi, you only need a patched kernel for your primary rom. You can use any other kernel, including stock, for secondary roms.

Do you have details about flashing Linux on the N7 2013? I couldn't find anything much when I googled it.

I'm currently trying to get the "complete Linux installer" app to work. I've gotten Ubuntu to mount and work with ssh successfully with the terminal emulator by making changes to the bootscript, but no luck so far with vnc. I think I'll have to unpack the image and change the file system to ext4, but I haven't had time. As for truly flashing Linux, I found a few success stories using a modified Ubuntu image, but they removed the stock image. I haven't heard of anyone doing it with multirom... Yet. But that's my next project.

You might want to follow this thread: in which the official LinuxOnAndroid-developer states that he is working on a fix for 4.3 host-devices.

Thumbs up
Just an update... I flashed multirom successfully, and complete Linux installer now works with flo! Some images work better than others, I've had great success with the Ubuntu small image.

Excellent news razrhackr!

Would you be able to link to a thread with a MultiROM image or a guide on how to do the same.

Thanks
