[XPERIA X1 Q&A, Help & Troubleshooting] HackitZ:
Hi everyone,

I have had this new xperia and love it, I have decided I would like to update my rom but want to make sure I have not missed anything.

If it's not to much to ask can someone let me know if this guide is missing any steps.

my phone and me are both virgins.

Thanks

------------------------------------

Preperation:

1. First lets download all that you will need in order to flash your rom.

Hard_SPL_X1_V1-

And of course download any custom rom made for the X1 of your choice...that is all you will need!

2. Extract the HardSPL somewhere on your pc, you might aswell extract the rom file somewhere on your pc too.

3. Connect your phone via activesync to your pc

4. When you are connected, (I let it finish synchronising one last time, to ensure all of the data on my pc was up to date with the current data on my phone), you then go to where you extracted "X1_HardSPL.exe" and you run it...

5. Follow the instructions at some point it should say something like "Image Version: 1.02.111.7" to "1.00.X1"

When asked, press "Yes" on the X1

6. - Now a Tri-color screen should show up, showing some version Information

After that, a progressbar screen will be shown and the phone will reboot when finished

Click "Finish" on the PC

(To check if you succeeded, turn the device off (long power button press). Then hold the volume down button and turn the device on again, still holding the volume down button until the Tri-color screen shows up. It should read something like:

KOVS110

SPL-0.72.OliNex

MicroP1-787

MicroP2-707)

Remove and reinsert the battery to exit bootloader mode

You completed the first step and are now able to flash any ROM you want to your X1! (Well, at least any ROM made for the X1 of course ;-))

Steps 2-6 need only to be done once...from here on forward should you wish to flash another rom you do not need to install HardSPL again as it is already on your phone.

Flashing your Rom (The fun begins):

7. Rename the rom file you downloaded from whatever.nbh (usually it is ruu_signed.nbh) to Kovsimg.nbh (you can rename it on your pc or on your phone once you have transferred it over)

8. Start up the phone normally, if you have not already done so...then connect it to your pc...(at this point you can connect it without activesync, just as a memory card reader so that you can copy over your rom faster)

Copy your rom into the root of the memory card.

(You can also use any external memory card reader/writer connected to the pc and copy over the file)

Remeber to make sure all files have been deleted off your memory card.

9. Insert the memory card into the phone (You never know somebody might forget to do it :-S )

10. Turn off the phone completely, not standby mode (USB cable must not be attached)

11. Remove and reinsert the battery (This step can be skipped if you made sure you turned off the phone in step 10, this is just in case somebody put the phone in standby instead)

12. Hold down the volume down button and press the power button while still holding both of these buttons until the tri-color screen pops up.

13. Follow the onscreen instructions (It should install the rom +-5mins)

14. When you see the screen say "Succesfully updated", you can then go ahead and remove the battery and reinsert it.

Getting ready to see results (one last step):

Do not skip this step!!! This may result in errors!!!

15. Do a hard reset : Hold down the two silver buttons directly under the screen, while holding them down push the power button, you should then be presented with a screen that asks you to press "R" to reset your device....so go ahead and flip open the keyboard and press "R", when it completes it will ask you to press "Spacebar" to restart the device...go ahead..

16. You are done!

You have now flashed your rom....after it restarts please note the first time it starts up again will take longer than normal, you will be presented with all the normal setup's as you first did when you got your phone...

Like stylus setup and time and date etc...

With this particular rom that I flashed approximately 3/4mins after getting to the today screen a notification came up asking me to choose my operator and it then installed all the necessary connection settings for me....

You may also be asked to restart the device once more after the initial startup of the new rom, this is because upon first start up the rom may install some additional programs / cabs / tweaks which the "cooker" has cooked into the rom....

I cant think of anything more at this point, I tried to be as detailed as possible with this guide and use as much lame-man's terms as possible to make it clear and understandable....

If you have any queries please do not hesitate to post under this thread and I will answer to the best of my knowledge...

Once again thanks to XDA-Developers from whom I have learnt all of the above....
