TWRP Holofied MultiROM theme updated

TWRP Holofied MultiROM theme updated:

Grab it here.

04.02.2014

Added cursor.png (mouse support)

Added "restart system" button to all MR related "action done" pages

Added option to "multirom settings" for displaying full MR recovery version number

Added option to "settings" for using Aroma File Manager instead of TWRP file manager (big thanks to [MENTION=4399618]nijel8[/MENTION] for the idea)

HOW TO USE AROMA FM:

Download this flashable zip.

Flash the zip in recovery.

It will copy the flashable Aroma FM package to \TWRP\aromafm.

Go to "settings" and tick the option to use Aroma FM.

Profit.

Hi guys.

Im having a lot of trouble installing GApps under MultiRom. Every time I try to install it, it fails. Ive tried a few different builds of GApps, & all have failed. Any ideas how to over come this ?

Btw, Im duel booting Stock 4.4.2 & OmniRom on my Nexus 7 2013 LTE. :confused:

I'm having a little problem with multirom now. I had it all installed and working fine before. But now after I decided to completely redo my N7 its not working properly. Multirom installs fine. The 2nd ROM installs. But no matter what ROM I try as the 2nd ROM I keep getting bootloops.

When I redid my N7 I completely removed and formated the internal SD. And thought recovery I whipped and formated the system, data, chache, and delvik chache. I forgot to run the multirom unimnstall script before doing this. But I did it after this problem and reinstalled multirom and still having the 2nd ROM bootlooping. How do I go about fixing the problem? Should I try the superwhipe script?
[Nexus 7 Original Development] s33d1ing:
Try wiping cache and dalvik on the secondary rom. Ive run into that problem before and that fixed it.
[Nexus 7 Original Development] CptKlink:
Thxs that did help but also diden't at the same time. I did whipe both of them after i installed the 2nd ROM. I always do after every ROM install. But it diden't work. But i desided i will try and wipe them again and it worked kinda. It was stuck at the Starting Apps screen and restarted the N7 and this time it finished the boot and it is fully working now. Desided to test a few other ROM installs and now i have to run through the exact same things to get the rom to boot.

After ROM install i wipe delvak and cache reboot, let it load till bootloop reboot, go in to recovery wipe dalvik and cache reboot, let it boot till it gets stuck at the starting apps screen reboot, then finnaly it will start up.

I have to do this with every ROM I install to get the rom to work. Or else the ROM with be stuck in a bootloop. Somethings not right but i'm not sure what.

Hi and thanks for this amazing tool.

I'm trying to get a TP-link wifi usb dongle (with htc_9271.fw, ath9k_htc)to work on Ubuntu desktop (13.04), but whenever i try to install drivers for it i get:

"ERROR: your kernel has CONFIG_CFG80211=y, you should have it CONFIG_CFG80211=m if you want to use this thing"

- this comes from the compat-wireless package.

My problem is that i've never compiled linux kernels before, so I wouldn't know where to start. Is there a way to get this to work? Or maybe a workaround?

Thanks

This may be a starting point to try and get a grasp of what is going on. However, I doubt it will guide you to developing a TWRP with both MultiROM support and All-F2FS support. Its just a starting point. ROM's and kernels are getting F2FS support at a very fast rate. Somehow I doubt there can be one version of TWRP that can support both scenarios, maybe one for ext4 and one for f2fs. Not sure both file systems can be supported at once, but your the genius, LOL, you tell us if its possible... hehe ;)

I'm not sure if this helps, but it is legolas93 that has been doing the work to get this F2FS adopted. Here is his modified TWRP recovery thread. I'm pretty sure you've seen it but just in case not, here it is again.

Does anyone know where I can find the CyanogenMod 10.1.2 kexec-hardboot patched for Grouper? All I can find is 10.1.0
[Nexus 7 Original Development] droidshadow:
looking for kexec patch for aosp jelly bean rom for nexus 7 model deb

Hello Everyone!

So first off let me say how much i enjoy using MultiROM, I have been such a big fan of this project. Many thanks to the developer!

Well i have a bit of a unique situation. If any of you are familiar with the PwnPad project from the guys over at pwnieexpress.com I installed their ROM for penetration testing purposes on my newly acquired Nexus 7 2013 Model DEB tablet. Now this ROM is AOSP based running on JB 4.3.1.

Now i installed MutliROM and I wanted to installed OmniROM as a secondary ROM but i forgot that I need the kexec-patch. Can someone please point me to where i can get the kexec-patch for the Nexus 7 DEB tablet running AOSP on JB 4.3.1

Also...I am wondering about one thing. You see the ROM that I am using for my N7 Model DEB tablet is a custom kernel for the PwnPad CE ROM. This kernel is used to support usb wifi devices so that I can use external usb wifi devices for wifi scanning for linux programs such as aircrack-ng, kismet, and wifite. The thing is...i am concerned that if i do in fact flash the kexec-patch that it would replace the kernel i have and it would render my ROM useless. Does the kexec-patch replace the existing kernel or does it in fact just patch the kernel, and I would still be using the kernel with usb wifi support? I really hope someone can help clarify this for me!

I would truly appreciate it.

-droidshadow
[Nexus 7 Original Development] Erovia:
You need a kernel that contains the patch. If you have the rom's kernel's source then you can add the patch, compile and use it.

If you flash a kernel that already contains the patch, it will overwrite your curent kernel.

Unable to Add Ubuntu Desktop in Multirom TWRP 0308

Hi, so i followed through the instructions and had no problem install ubuntu touch into my nexus 7 2013 wifi, but when i want to install ubuntu 13.04 i couldnt find "add ubuntu" under TWRP- Advanced- Multirom- Add ROM. I saw options such as "Add Android" "add ubuntu touch" and "multirom installer" though.

Does anyone know why? How should i get around it and install ubuntu desktop 13.04?

Actually, the "add ubuntu" button has been gone for a while now. You have to install it like a generic linux distro. farmerbb is right though. I've tried installing it on the nexus 7 2013, and it hangs on the google boot logo.

Hi, I finally managed to get enough time to install Multirom on my N7 and I totally love it!

I would like to ask you, whether or not is it possoble to have two different ROMs one vith 4.1.2 and the other with 4.2.x. ?

Well, I need the later only to check whether or not the apps I need has started/stoped working in stock rom. But as I understand, Android v 4.1.x uses different directory structure than 4.2 and I am not sure that I really understand how mutirom manages the Nexus storage, so I fear that there might be some conflicts concerning directory structure and/or access rights...

Can anybody confirms whether it is working correctly or not, or how to make it work correctly side-by-side? (I hope I did not miss the answers somewhere in the thread:angel:)
[Nexus 7 Original Development] Tasssadar:
UPDATE: kexec-hardboot thread: http://xdaforums.com/showthread.php?t=2104706

Important!

MultiROM v3 and higher requires kexec-hardboot patch in kernel to boot Ubuntu and Android ROMs which do not share kernel. Patched kernels for stock 4.1 and 4.2 and Cyanogenmod 10.1 are in the second post.

If you're using different kernel, ask your kernel's dev to merge this patch: https://gist.github.com/4558647 (this is for CM10 kernel, but stock one should be similiar, if not the same)

Just give them the link (or link to this post), they're gonna know what to do. And by ask, I do NOT mean "spam the hell out of their forum threads".

@Kernel devs: This is a kexec-hardboot patch. The functionality is basically the same as "fastboot boot boot.img", but without the fastboot. I use it to run different kernels without changing the boot sector. It works like kexec, but with real device reset - normal kexec cannot be used because it just freezes on N7. I've ported it to Nexus 7 from the Asus TF201 code, with help from people at #ubuntu-arm IRC. It touches relatively stable parts of kernel and it is pretty smallnot-that-big. Should not cause you any trouble, so I am asking you to merge it into your kernels.

PS: don't forget to enable it in .config

PS2: just FYI, github can make .diff and .patch from commit very easily - just add ".patch" or ".diff" to the end of commit's addres, like so: https://github.com/Tasssadar/androi...1d308e794d077b60d193fae5f03d1d6fcd63fa2.patch

Does that mean that 12.10 support will be dropped or you will support both versions?
[Nexus 7 Original Development] Tasssadar:
Not sure. I would _really_ like to drop 12.10, because kexec needs some patches in the ubuntu kernel, and they are only in 13.04's kernel (12.10 is no longer being updated, I think). I'll see. Is it a big deal for you?
[Nexus 7 Original Development] Rafase282:
Well I have my setup completed on 12.10 but if it wont be updated an all that I would switch, but it would be nice to keep the support as I would keep the rom until the new version is significant better.

I flashed multirom zip through TWRP and flashed modified TWRP on mmcblk0p1(I don't have computer, so made flashable zip).

It seemed to be working, but I figured out that "Adding rom" doesn't work.

It doesn't copy any files from zip, only boot folder was created.

What should I do?

EDIT:NVM. Fixed it by flashing recovery.img on page 14.
[Nexus 7 Original Development] Tasssadar:
Which ROM do you have? Also, in my experience, media scanner stops ~30min after boot. Yours does not?

I've just installed it, and media scanner stopped ~20mins after boot. Don't disable it, wait for it to finish. Or does it not stop on your device?

Have you been able to get this feature straight for it to work with all F2FS ROMs? If you have, will I be able to still install Ubuntu as well? I'm not sure if I can even mix ext4 ROMs in as well now that I'm formatted to all F2FS. I tried once you first released the test build for F2FS, but I was getting bootloops and decrypted storage password prompts. I have no idea even what the default password for that was, much less what the hell I was really trying to accomplish by mixing these ROMs. I just could not get it to work. Maybe it might work to some extent now that my internal is formatted to F2FS?

Thanks for your time, sorry I'm so ignorant to how your module works and not knowing if its even possible to work, but your test release got me wanting to try something because multiromming is just awesome! ?
