[Xperie Z Ultra/Z3/Z2][Mód] MultiROM v30x

[mitsuu84]

Jedná se o multi Rom pro Xperii Z ULtra.Na této rom jde slustit libovolná ustom ROM i porty třeba Ubuntu (pokud port na Ultru je).Kromě spouštění z interní paměti zařízení,MultiROM může bootovat z USB disku připojeném přes OTG.Hlavní část MultiROM je manager boot,který se objeví pokaždé,když se spustí zařízení a umožní vám vybrat,kterou ROM chcete aby nabootovala.Podle mě parádní fěc pro někoho,kdo rád testuje/mění ROM.Jen se v tom zorientovat

Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via OTG cable

WARNING
It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always

Installation
1. Via MultiROM Manager app
This is the easiest way to install everything MultiROM needs. Install the app and select MultiROM and recovery on the Install/Update card. If the Status card says Kernel: doesn't have kexec-hardboot patch! in red letters, you have to install also patched kernel - either select one on the Install/Update card or get some 3rd-party kernel here on XDA. You are chosing kernel for your primary ROM, not any of your (future) secondary ROMs, so select the version accordingly.
Press "Install" on the Install/Update card to start the installation.

2. Manual installation
Firstly, there are videos on youtube. If you want, just search for "MultiROM installation" on youtube and watch those.

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-vXX-DDMMYY-togari.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom-togari.img) - download the IMG file from second post and use fastboot to flash it.
Patched kernel - You can use third-party kernels which include the patch, you can see list in the second post.
You current rom will not be erased by the installation.
Download links are in the second post.


Adding ROMs
1. Android
Go to recovery, select Advanced -> MultiROM -> Add ROM. Select the ROM's zip file and confirm. As for the space, clean installation of a ROM after first boot (with dalvik cache generated and connected to google account) takes more or less 700MB of space.


Using USB drive
During installation, recovery lets you select install location. Plug in the USB drive, wait a while and press "refresh" so that it shows partitions on the USB drive (if USB drive partitions are not showed, disconnect USB drive and try again). You just select the location (extX, NTFS and FAT32 partitions are supported) and proceed with the installation.
If you wanna use other than default FAT32 partition, just format it in PC.

If you are installing to NTFS or FAT32 partition, recovery asks you to set image size for all the partitions - this cannot be easilly changed afterward, so choose carefully. FAT32 is limited to maximum of 4095MB per image - it is limitation of the filesystem, I can do nothing about that.
Installation to USB drives takes a bit longer, because the flash drive is (usually) slower and it needs to create the images.
Enumerating USB drive can take a while in MultiROM menu, so when you press the "USB" button in MultiROM, wait a while (max. 30-45s) until it searches the USB drive. It does it by itself, no need to press something, just wait.


Updating/changing ROMs
1. Primary ROM (Internal)
Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.
2. Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
Select "Flash ZIP" and flash ROM's ZIP file.

na g3 to pouzivam a teda je to celkem dobry

[mitsuu84]

Já se v tom teprv musím nějak zorientovat co a jak přesně .Ale nadchlo mě to

[mitsuu84]

Nevíte někod o kernelu co funguje na ofiko firmwaru 4.4.4 a má kexec-hardboot patch ?Bez toho tenhle mod nerozjedu.

[ShockeyCzT]

Na xda zatim nikdo neudelal?

[mitsuu84]

Je tam,ale to jede na CM/AOSP ROM,takže na ofiko ne.DoomKernel to nemá v sobě.Píše tam,že bud nainstalovat přes menu (v tý aplikaci) ale tu volbu mám šedou a nejde zaškrtnout a nebo kernel od jiho developera (nepíše jaký) a ty co tam su,na ofiko firmware nejdou.A já chci ofiko jak sekundární právě.

[ShockeyCzT]

Divny tak leda pockat jestli to tam doom da dodatecne me to pres apku taky neslo nastesti uz jsou ale kernely jak pro custom tak i stock rek bych ze je to jen otazka casu

[mitsuu84]

Budu muset počkat asi no.Ale zas sem čuměl,že Doom má takt 2.5 Ghz a na CM/Aosp sem našel kernel co de až na 2.7 Ghz.Což proti původním 2.2 je paráda ( i když 2.2 bohatě stačí).

[ShockeyCzT]

Ono cpu je celkem zbytecny taktovat co je ale dobry ze v nejkterejch kernelech je moznost nahnat takt gpu ze 450 na 657mhz coz uz je znat a v antutu to pridalo pres 2k na hodnoceni u z1

[mitsuu84]

Já ti ani nevím jak na tom bylo GPU u Dooma,ale výsledek v Antutu byl vyšší jak ve stock stavu.
