[XPERIA X1 Android Development] kerfooly:
About

This thread contains all the Android NAND development that is going on in different websites like Github.com

The developers are not responsible for any damages happened to your phone in any way so be aware of what you are doing

Note that the development is still in "Beta" state and it has few issues which are still under development, the Android NAND ROMs are almost ready for day to day use

you can always switch back to any windows mobile ROM by flashing the official or a custom windows mobile ROM just like when you had windows mobile using any Sony Ericsson Xperia X1 ROM Update utility or the SD Card (KOVSIMG.nbh) method, as the SPL or windows mobile's bootloader will not be effected

there will be few random screen flashes when the device start even when you shift back to windows mobile but this does not effect the performance of the device in anyway

Your SD Card Android ROMs are not going to be effected but you wont be able to run them unless you re-install Windows Mobile again

below is the list of whats working and not working so far

Downloads

below is the list of Files which are required

HSPL 0.78 (optional)

Download it from here if you haven't install a Custom ROM before or you are on initial HSPL 0.72

A ROM update utility (optional)

Kovsky Advance ROM update utility is recommended as Its easier to work with, but the official RUU and SD Card method will do the same

Latest Android bootloader

Download the latest bootloader available here

Android Driver and Fastboot

Xperoid installer is recommended as it contains the necessary files of Android SDK only and can do the job automatically,

Latest Android Recovery

Download the latest recovery available here

Latest Android Kernel

Download the latest Kernel available here

An Android ROM

choose and download your favorite Android ROM from here or here

Video

Here is the video of how to install any NAND ROM, lots of steps have changed but the main procedure is the same

PART 1

PART 2

1.HSPL

If you have already installed a custom Windows Mobile ROM and have the 0.78 version skip this part, to know about your SPL version turn off your phone, hold Volume down button and while holding hold the power button till you see the Tri colour screen which is the SPL; If you have Olinex name on any line, you have HSPL,

SPL is like your devices BIOS, and Hard SPL will unlock your devices bootloader to allow you to install any custom made Read only memory (ROM)

to do a HSPL refer to THIS thread

(if you had a problem in performing a HSPL, read the replies at the end of the above thread as there were some users not being able to HSPL the normal way and had to do few other steps)

2.Android BootLoader

Put the .zip ROM you have downloaded in the root of your SD Card before you do anything further; which means put the .Zip file in E:\ROM.zip if your SD Card drive letter is E

HTC Linux LK bootloader allows the device to run the kernel directly after it got turned on

Install it just like the way you install any other Windows Mobile ROM, which is using a RUU or the SD Card method

It is always recommended to do a Task29 before you flash an Android Bootloader if you know how to.

(Kovsky Advance RUU)

3.Kernel

Kernels are like drivers in PC, it connects and manage the hardware of the device

they have to be installed using Fastboot. Fastboot is a command line tool used to directly flash the filesystem in Android devices from a host via USB.

>For Windows users

Extract Xperoid Installer

Rename the Kernel you have downloaded to boot.img, then place it in the Xperoid fastboot folder

Rename the recovery you have downloaded to recovery.img, then place it in the Xperoid fastboot folder

connect your phone and install the drivers from Android USB driver folder

then simply run Xperoid Fastboot installer.bat from the Xperoid fastboot folder

>For Linux based OS users

follow the instruction on This page

5.Recovery

ClockWorkMod Recovery is like the BIOS in PCs, which is the software that can install and manage the device's software

To go into recovery turn on your device and as soon as the phone starts (Sony Ericsson logo stage) hold the Camera Focus button which is holding the Camera button half pressed till recovery starts, (it might take few seconds to load)

once you are in recovery use the touch pad to go up and down, power button to go back and middle button to select trough the menu,

Go to mounts and storage> Format Data

Go to mounts and storage> Format Cache

Go to mounts and storage> Format dalvik cache

go back to main menu

Go to install zip from SDcard

select the file and install it

after installation select restart system now

Remove the SD Card and the battery, put the battery in, turn on the phone and wait till it completely start up

Re enter recovery with SD Card inserted and install the GAPPS

Load the system without SD Card and sync it with your accounts and open all the apps once and then restart again and once you are in android again insert your SD Card

If you are updating your ROM from an earlier version of NAND Android ROM

Download the full wipe script and put it in the root of SD Card

Go to backup and restore

select Backup

go back to main menu

Go to install zip from SDcard

select the full wipe script.zip and install it

go to main menu

Go to install zip from SDcard

select your new ROM and install it

go back to main menu

go to backup and restore

go to Advanced restore

select Restore data

go back to main menu

select restart system now

Recommendations:

Booting with SD Card inserted:

As you might have notice in the guide, the Kernels have a major bug of not being able to boot the ROM with a normally formatted SD Card inside the device. so we have to format the SD card in a special way to bypass this problem

To do so follow this guide

You have to perform these recommended actions for better performance

Back to Windows Mobile:

In order to switch back to any windows mobile ROM, enter the Windows mobile bootloader (SPL) by turning the device on while holding Power and Volume down buttons together, and once you entered SPL simply flash the ROM as you did earlier

It is always recommended again to do a Task29 before and a Hard reset after you installed a Windows Mobile ROM

report back your issues and problems for faster and better ROMs in future.
