Sorry for noob question. Can i used 'strikerz1-kai-rom' for secondary?

If yes how can i flash kernel for secondary rom?

Sorry again
[Xperia Z1 Original Android Development] Chocolatetrain:
Yeah, just flash the zip twice, then a kernel, that's what I did
[Xperia Z1 Original Android Development] mynNeyl:
Thanks for your help. Can you share me a link to flashable zip for kernel. I only has img files for kernel.

Mind asking what is your primary and secondary rom?

Thanks guys for suggesting the solution/workarounds!!:good:

I found another workaround!!

I installed the MIUI rom on external SD card as my third rom, with this had booting issues with my second rom (RR Lollipop).

I tried to dirty flash the RR Lollipop rom but it was giving lot of FCs. So, deleted it and again installed in internal memory.

All the 3 roms (Stock-primary; RR lollipop-Second and MIUI-third) are booting beautifully.

No issues at all.

Now finding/waiting for FireFoxOS to try out.:p I know i sound stupid to try out all these :p
[Xperia Z1 Original Android Development] xxx_sunnyboy_xxx:
Yes I hope that too... [emoji2]

XKernel und maybe CoCore Z Kernel will Support MultiROM with the next build.

Foa sorry, but I did not find anything about Multirom for exactly my Device.

I am owner of a Z1 compact (D5503) with Multirom, all working fine with any ROM, but..

I tried to install Stock Lollipop for testing, but it crashes while bootig. A member of another forum told me that the reason is probably the size of the ROM (about 1.3GB). Ist there any way to install it anyhow as second? Dont want to change my primary.

Thanks

[Xperia Z1 Original Android Development] waagbull:
I had a similar "problem" earlier when I tried to use a backup made with Philz Recovery on Twrp. I found out that to restore a backup in Twrp You have to use a backup that was made in Twrp ;) There may be another way to make it show up in backups, but I just went back to Twrp and made a new backup from there, and then it showed up in backups as normal. :)

Hope this helpes You out ;)

Ubuntu Touch on Xperia Z1 C6902

Hi guys, I'm probably gonna ask a very n00bish question, sorry for that. I'm on a C6902 and have successfully installed multirom and the 4.4.A.0.157 build with a kexec hardboot modified kernel. Now the thing is that I really would like to try Ubuntu Touch on it, but I still get the "Unfortunately, Ubuntu Touch does not support this device" error within multiboot, thus making it me impossible to install Ubuntu Touch this way.

Is there any other way I can install it? Thanks a lot in advance.

And last but not least: Thanks everyone here for all the good work and helpful messages. I would not have been able to get this 'far' without all of you. Thanks a lot!

[Xperia Z1 Original Android Development] vshzR:
I have been looking up this issue for the past few days, however I am unable to find any resolve and maybe posting here could help. I have been using Multirom for quite a bit, however I reached a point after I did an update a while back which has stopped me completely from getting on to TWRP so I cannot flash anything new. I have tried using the app to set everything up however it reboots to recovery and its the stock recovery with the exclamation point. I am presently running Euphoria rom from May of this year because I cannot flash anything new. I already have the uninstaller downloaded for MultiRom, but I am literally at a loss for ideas to go any further... Any ideas?
[Xperia Z1 Original Android Development] drakonizer:
You need to flash the multirom recovery to the FOTAKernel partition. If you're not interested in multirom, you can flash any other recovery to the FOTAKernel partition using:

fastboot flash FOTAKernel recovery.img

where recovery.img is the recovery you wish to flash.

i prepared a NTFS-Partition (where TWRP tells me it cant access it) and a ext4-Partition (where TWRP tells me the install-image is to big).

is there any solution?

can i install f.e. the MX rom normal on internal, and copy then the whole installed system onto the SD-Card?

can i make i Backup from the the "normal" installed "big" images?

I am using unofficial MultiROM on my LG P880 for a long time. But secondaries, that need a different kernel from main ROM without kexec Hardboot Patch, won't work on this device.

03. The same

04. /dev/block/mmcblk1p1 is external SD card

05. That means that they have block images, I'm already working to solve this issue :)

06. Yes, that happens only if a Lollipop is the main ROM, I don't know why, but I'll work on it.

No, here you just need kexec hardboot patch for primary kernel.

And how is this expected to be helpful? :confused:

BTW, that patch uses an incorrect kexec hardboot page address.

Aroma doesn't work, maybe try using the ST ROM as a template for the updater script, move the aroma files you want into the system and then replace META-INF folder with ST Ultimate's script to see if it will work properly. I haven't tried it myself though

Edit

; latest MIUI with aroma works, installs properly and everything, as long as you replace the boot.img and modify the updater-script since apparently it isn't using LZMA compression. But then when booting it says failed to boot. I can post the modified updater-script if you guys want me to.
