Install rom worked for me too, but "list roms" menu doesn't work and I cannot install zip (like gapps) and neither remove secondary roms. (SGP311)
[Xperia Tablet Z Original Android Development] pollonamid:
Ok. Thank you for Feedback. I will look into it.
[Xperia Tablet Z Original Android Development] phillipssat:
How did you install the gapps ?? Dont know from where...
[Xperia Tablet Z Original Android Development] pollonamid:
It should be in advanced -> multirom -> list roms. But it looks like this menu does not work in landscape.

[MENTION=5939791]pollonamid[/MENTION]

I'm lost here...

*Flashed newest recovery (dd if=/sdcard/Download/openrecovery-twrp-2.8.0.1-pollux_windy.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel)

*Flashed multirom.zip via recovery

There are no options in recovery (in Advanced) for multirom.

:confused:
[Xperia Tablet Z Original Android Development] pangiotis24:
I don't know what multirom.zip exactly does but i believe it doesn't touch fotakernel partition.by flashing newest recovery you installed it on the fotakernel partition.When the systems boots fotakernel recovery(if it is installed) is preferred so you need to wipe fotakernel partition recovery
[Xperia Tablet Z Original Android Development] SnZ:
Will try that in few hours and post results :)

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel

Did the job :)

I guess I'll start looking later to compile my own with new TWRP or just compile Multirom TWRP so I can flash @ fota (feels more safe that way).

Any progress with stock rom support?
[Xperia Tablet Z Original Android Development] pollonamid:
Stock rom support is next on my list. Currently tring to compile the stock kernel. Never done this before :laugh:
[Xperia Tablet Z Original Android Development] `SBR`:
Trying this now...Will it work with other aosp rom as host or any patch needed as I can't find omni for pollux
[Xperia Tablet Z Original Android Development] pollonamid:
It should work with every rom that has an kexec-hardboot enabled kernel. As far as I know this is just OmniROM. You can use my OmniROM builds for SGP321. (here)
[Xperia Tablet Z Original Android Development] skiwong20:
i have made PAC with kexec hardboot for u guys..

get it HERE

I have multirom running with cm11 as internal rom. I started with a completely wiped clean device, this is most probably not necessary but I wanted to wipe it anyway.

1. Installed cm11 latest nightly

2. Flashed Lightning Kernel: http://xdaforums.com/xperia-tablet-z/orig-development/lightning-kernel-cm11-t2882633

3. Installed TWRP 2.8.0.1: http://teamw.in/project/twrp2/185

4. Installed MultiROM

5. Ran command from Post #49 thanks to [MENTION=4217156]SnZ[/MENTION]

su

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel

I then installed OmniROM as a secondary multirom, but afterwards MultiROM complained and would not boot into the secondary ROM so I had to reinstall the Lightning Kernel (step 2) in order to boot from a multirom. Also I lost the MultiROM option in TWRP so I had to also run steps 3 & 4 to get that option back.

Next up was PAC ROM as a secondary multirom. Rebooted and presented with MultiROM boot menu with CM11 (Internal), Omni and PAC. Choosing PAC caused no such issues and MultiROM worked first time. Rebooted into TWRP and MultiROM functionality was still there and working fine but TWRP was now at 2.8.0 level and not 2.8.0.1 and TWRP crashed a during MultiROM work.

Again, ran steps 2, 3, 4 & 5 and all was well again so seems normal

Now I have cm11 as internal ROM, TWRP with MultiROM and Omni and PAC as secondary ROMS.

There are much easier ways you can have MultiROM as mentioned in the OP but this is one method for keeping CM11 as Primary...even if you have to rerun a few quick steps each time.

SGP312 pollux_windy
[Xperia Tablet Z Original Android Development] Rootk1t:
so there is a way to have several ROM as secondary? That's great:good:

Though, you can't use 3 ROMS simultaneously))))

Stock ROM/Custom ROM (CM, OMNI, PAC) would be more practical.
[Xperia Tablet Z Original Android Development] pollonamid:
I tried out what you wrote but on my SGP321 it worked much easier :D

I installed the most recent cm11 nightly.

After that I installed Lightning kernel (here)

Then I installed the multirom zip and rebooted. From there on multirom worked.

I was able to install Omni and Pac as secondarys without any problems. All of them boot and work fine. I don't know what went wrong on your device., but happy to hear that it's working now.
[Xperia Tablet Z Original Android Development] cantenna:
All that we need now is a flashable stock 4.2.2 ROM.zip and we are golden :)
[Xperia Tablet Z Original Android Development] Rootk1t:
not 4.2.2, but latest 4.4.4;)
[Xperia Tablet Z Original Android Development] cantenna:
Yes 4.4.4, (was drinking when posted, me thinks)
[Xperia Tablet Z Original Android Development] skiwong20:

[Xperia Tablet Z Original Android Development] Lupin The Third:
Any news regarding stock rom support?
[Xperia Tablet Z Original Android Development] skiwong20:
not sure about OP..but i am willing to try. will take a look at it..no promises
[Xperia Tablet Z Original Android Development] `SBR`:
Any change log for the update..

Thanks for sharing
[Xperia Tablet Z Original Android Development] skiwong20:
sorry no changelog.. i mostly just changes to follow what Tassadar is doing for is official devices..

i have made another update today to have the new multirom twrp recovery version (2.8.1)

Pollux

pollux_windy
[Xperia Tablet Z Original Android Development] scoobydu:
Any news on that would be great :)

Thanks OP for the multirom support,

Stock with CM11 as secondary would be wonderful! :)
[Xperia Tablet Z Original Android Development] phillipssat:
I think there is no Chance for original Rom support.... ?

Sent from my SGP311 using omnirom
[Xperia Tablet Z Original Android Development] pollonamid:
Thank you for the builds. I was busy the last weeks with moving house and stuff. But now I have time again. :)

If you don't mind I link your builds from the first post.

I don't think so. :D

I got it working on pollux. I'm currently working on the pollux_windy kernel, but I need someone to test it.

Someone with unlocked bootloader and Sony Stock-Rom v. 10.5.1.A.0.x.
[Xperia Tablet Z Original Android Development] phillipssat:
Stock as master are as second/third Rom ??
[Xperia Tablet Z Original Android Development] pollonamid:
currently master only. On secondary it just bootloops. :(
[Xperia Tablet Z Original Android Development] phillipssat:
When you got it, hopefully you can also transform the coming Android 5.0 for z-series.....
[Xperia Tablet Z Original Android Development] pollonamid:
It should be possible. The Xperia Z has a working android 5 build already. And Xperia Z and tablet Z are nearly the same.
[Xperia Tablet Z Original Android Development] skiwong20:
Pm if you want me to test the Pollux_windy stock kernel with kexec patch. I have been too focused on my phone getting lollipop..time for me to look at tab to give it love too
[Xperia Tablet Z Original Android Development] scoobydu:
That's excellent news indeed :)

Thanks for your time in doing this!

Did you manage to test the kernel as yet?

Also, appreciate that its not stated on the first post as supported, but are the current cm11 nightlies supported as a secondary rom, once you have the stock kernel working with the kexec patch?
[Xperia Tablet Z Original Android Development] pollonamid:
Yeah. It should work. I will upload it today.

The listed roms are host roms only. They have an kexec kernel. Secondary roms don't need special edits. In theory every android rom should work.(except stock)

So yes, cm11 can be installed as secondary.
[Xperia Tablet Z Original Android Development] pollonamid:
I uploaded the boot.img's.

pollux_windy: https://www.androidfilehost.com/?fid=95784891001612021

pollux: https://www.androidfilehost.com/?fid=95784891001613125

Happy flashing.
[Xperia Tablet Z Original Android Development] scoobydu:
Ok thanks, that is what I was used to with the OnePlus implementation, but I have missed that they were host roms.

Working great for me on my SGP312, so thanks for that.

One small point is that if I select to boot to recovery from the rom boot menu it still boots into recovery when the rom is selected to boot normally from the multirom rom menu.

Also, would you have any plans of supporting the multirom manager app at all?
[Xperia Tablet Z Original Android Development] pollonamid:
I don't really understand what you mean. Could you explain?

I can try. I'm not really experienced in java.
[Xperia Tablet Z Original Android Development] scoobydu:
No issues with the multirom app, its a nice to have.

The other issue is also not major once you know it. Maybe its sorted in v30.

If on xperia rom you selected reboot and then select boot to recovery it will reboot and go to recovery.

If you then reboot from recovery you go to the multirom menu and select xperia rom, it will somehow remember that I previous booted to recovery and boot back into recovery, even though I selected to boot the xperia rom.

Not sure I have better explained, but not an issue to be honest.
[Xperia Tablet Z Original Android Development] pollonamid:
Yeah I understand now [emoji1] I didn't notice it till now.

Does this cm12 lollipop run with newest MultiROM ?

http://uploaded.net/f/4bbo69

http://uploaded.net/file/u7wobk17/from/4bbo69
[Xperia Tablet Z Original Android Development] scoobydu:
Not on v29 for me, but v30 runs lollipop fine on my OnePlus.

Hoping the OP gets some time between work to build the latest multirom :)
[Xperia Tablet Z Original Android Development] scoobydu:
Would there be any chance of updated file for the 312 for the new build 292 please.

Thanks in advance
[Xperia Tablet Z Original Android Development] SnZ:
Big ups for this :)

I installed over stock - working

added Omni - working

added CM11 without custom kernel... - working! (how is this even possible, they added kexec or what? I think you always need to flash lighting kernel) not that i'm interested in broken-gps-rom :)

Good work~!
[Xperia Tablet Z Original Android Development] pollonamid:
You only need kexec hardboot kernel in your host rom. Because that is the kernel that gets started at boot.

The other kernels then get started with help of kexec, so there is no need to patch them.
[Xperia Tablet Z Original Android Development] pangiotis24:
when you have time please build the latest multirom as it support multiboot with android 5.0 roms.Thank for your work
[Xperia Tablet Z Original Android Development] phillipssat:
Who is able to make a v30 for lollipop ??
[Xperia Tablet Z Original Android Development] scoobydu:
Hey [MENTION=5939791]pollonamid[/MENTION] do you need some coffee or beer to help you through this, or just time :)

Hope all is well and you haven't left us for good!
[Xperia Tablet Z Original Android Development] pollonamid:
Thanks :D

No, I don't need anything of that. I just lost motivation working on this cause of other private projects I was working on.

But yesterday I felt like working on this again. So here is v31x :good:

pollux

pollux_windy

MultiRom still needs a host rom with kexec_hardboot support kernel.

Lollipop Roms work fine as secondary roms.
[Xperia Tablet Z Original Android Development] scoobydu:
You sir are a gentleman and a scholar :)

Thank you for your time!

Edit: All working well and Cm12 now installed and working fine :) lovely jubbly
[Xperia Tablet Z Original Android Development] pollonamid:
nice to hear. What host rom do you use?
[Xperia Tablet Z Original Android Development] scoobydu:
Stock rom.
[Xperia Tablet Z Original Android Development] Shanliang-:
Thanks [MENTION=5939791]pollonamid[/MENTION] for such a good work! I've been reading the thread and haven't seen clear info about this:

I'm currently running 10.5.1.A.0.283 rooted stock firmware with dual recovery by NUT on my pollux_windy. I'd like to have CM12 as secondary. Would these steps be correct?

In fastboot flash boot_stock_windy.img

Boot to recovery and flash multirom-20150215-v31x-UNOFFICIAL-pollux_windy.zip

Reboot to recovery and flash CM12 and GApps.

I guess I'd lose dual recovery after doing it, right? Please, let me know if I'm on the right path. Thanks a lot for your guidance!
[Xperia Tablet Z Original Android Development] pollonamid:
Yes. Should work like that. Installing CM in recovery is then advanced-> multirom-> add rom.
[Xperia Tablet Z Original Android Development] Shanliang-:
I've finally managed to to install Multirom on pollux_windy.

I followed these steps:

In fastboot mode flash boot_stock_windy.img

Reboot the device and entered to recovery and flash multirom-20150215-v31x-UNOFFICIAL-pollux_windy.zip

In this part I got an error when trying to flash the multirom zip

script aborted assert failed: getprop("ro.product.device") == "pollux_windy" || getprop("ro.build.product") == "pollux_windy"

SOLUTION pollux_windy: I opened in my computer the multirom zip file using 7-zip (WinRAR works too) and went to this path /META-INF/com/google/android/updater-script. Right click that updater-script file and then Edit. Notepad opened and I erased all this:

assert(getprop("ro.product.device") == "pollux_windy" || getprop("ro.build.product") == "pollux_windy");

Saved the file, closed Notepad and the zip got updated. Do not extract the contents to do this, do it all inside the zip.

Now the zip installed perfectly and continued:

Reboot to recovery and in Advanced -> Multirom -> Add ROM -> Here you flash your new ROM.

Then Advanced -> Multirom -> List ROMs -> Here you select your new ROM, then -> Flash Zip -> Here you flash GApps.

And that's it, reboot and then you'll be able to select what ROM to boot! I hope this helped.
[Xperia Tablet Z Original Android Development] monivan:
I got black screen when trying to boot cm12 nightlies as a secondary rom. Primary rom runs just fine!
[Xperia Tablet Z Original Android Development] skiwong20:
i would try to reinstall it again as second rom...the newer build works fine. have beening test things and multirom always make it easier for me
[Xperia Tablet Z Original Android Development] K-NineHD:
It dosen@t work for me :( there is no multirom option in twrp, i was so excited to use it
[Xperia Tablet Z Original Android Development] pollonamid:

[MENTION=5939791]pollonamid[/MENTION]

ok i made a Candy LP rom with kexec patch and it seem to works, i can see MR manager showing up after kernel boot splash and i can choose like on xperia z

only thing is....i have twrp 2.8.5.0 on fota partition, and in "advanced" tab MR menu is missing, already seen this?
[Xperia Tablet Z Original Android Development] skiwong20:
its cause u need to remove twrp from your fota partition using dd and then flash the boot img. which will have a recovery and flash the multirom zip..the mutlirom recovery is in the trampoline zip..so after each rom flash to the internal you have to flash the trampoline zip no matter what
[Xperia Tablet Z Original Android Development] Alx31:
well, im speaking with Oliveer everyday....this multirom needs to go official as yuga in order to get the apk and make it works/compatible to fota recovery, it's such a great feature, thats odd all its potential not fully used!

Thanks a lot as well, will format my fota partition then :(
[Xperia Tablet Z Original Android Development] pollonamid:
Hi. I don't think that I'm the right person to make it official to the app. I just don't have the time to maintain and support it. If someone else has the time to maintain it I am available for questions. Please write me in hangouts.
[Xperia Tablet Z Original Android Development] Alx31:
I honestly have no time either...with this new kernel and other projects on the side...24 hours are not enough in a day ?
[Xperia Tablet Z Original Android Development] pollonamid:
I will see what I can do.
[Xperia Tablet Z Original Android Development] monivan:
I couldn't install CM12 on to external sd. It hangs with black screen. I tried to backup extern rom and install it on internal rom, it works just fine. Maybe I am using exFAT on my sd, or any one has the same problem?
[Xperia Tablet Z Original Android Development] phillipssat:
I was on qsnc cm12.1.

Then i flashed newest Dirty Unicorn and gapps 5.1with my TWRP 2.8.5.0

After that i flashed Multirom v31. Multirom starts no, without problems.

Now i cant find an Multirom- TWRP to Install second Roms.
[Xperia Tablet Z Original Android Development] rintala@hakunila.com:
i have that problem also... , not right recovery?? Someone tell us, right recovery.. ?
[Xperia Tablet Z Original Android Development] sknobli:
Hello, i also want to use MultiROM but it seems it was not installed correctly. Currently there are are TWRP 3.2.1-0 installed. After i installed the MultiRom.Zip it starts also with TWRP 3.2.1-0. Also Wipe does nothing better :(. Any suggestions to solve this issue?
[Xperia Tablet Z Original Android Development] Rootk1t:
MultiROM is not maintained for quite some time, and i presume it is not working with latest ROM as well.

Unfortunately while flashing a ROM i encountered an error, one of which has essentially corrupted my EFS folder.

This problem has led to an unknown baseband version and the inability to connect to a mobile network.

My phone is a GT-N7105t Samsung galaxy note 2, due to the problems it is now running stock firmware on Jelly Bean 4.3, my phone is of the Telstra model in Australia and i am using a Telstra Sim.

I have managed to exit factory mode but have made no other progress.

Please help I am in desperate need of it!

I will supply any other necessary information as to achieve functionality again.

Sorry if this is in the wrong thread.

Thanks in Advance.
[Galaxy Note 8.0 (Tablet) Accessories] dearsergio:
Did a quick search and didn't find what I was looking for.

I'm in the Navy and I keep PDFs of all important instructions on my Note 8. I use it all the time at work. I go to a lot of meetings and take notes on a regular 5.5 x 8 inch notepad, I have sticky notes, highliters, and an assortment of pens with me. Im looking for a case that will hold my Note 8 on one side, my notepad on the other side, ans still have slots for pens.

When I first got this I ordered what I thought was exactly what I described above on Amazon. When I got it, turns out the dimensions weren't exactly accurate . It's simply too big to walk around with all day. It's more of what I'd picture an art student would carry around.

I'm looking for something compact, not much bigger than the Tablet itself but with room on the opposite side for a notepad and slots for pens.

Im kicking around a few ideas on Amazon but im afraid to order without the opinion of someone who owns and uses one with the Note 8, in fear of another poor purchase.

Thanks everyone!!
[Galaxy Note 8.0 (Tablet) Accessories] GMan56:
I've been using one of the green "leader book" holders from Rite in the Rain for a little while now; item number C9200A. It's not perfect, and I haven't figured out a way to keep the Note 8 really secured in the binder itself, but there are several pen slots which are big enough to hold a highligher/sharpie/etc, and a few other slots and pockets for smart cards or anything else. And the dimensions are perfect for holding the tablet.

The ones we get from supply (I'm Army btw), come with a packet of inserts that has graphed notebook paper, and fillable pages for things like a 9-line MEDEVAC request, call for fire request, unexploded ordinance, and others. Some of it might be Army specific, but I'm sure you could find it useful too

Anyway, I've been in the same boat as you for awhile, and besides finding some "tactical" (lol) iPad Mini cases/binders, I haven't been able to find much. Let me know if you find something better!
[Galaxy Note 8.0 (Tablet) Accessories] dearsergio:
http://www.amazon.com/rooCASE-Samsu...&sr=8-2&keywords=galaxy+note+8+case+executive

This is one other I was looking at, but it doesn't look like it has any room for a notebook. We don't have a supply! But I'll look into what you posted and keep on looking for something. Right now I got a nylon foldable case from the Chaplains that's working well, but having the same problem as the tablet not being totally secure.

Also, it's big!

Thanks for the input!
