[XPERIA X10 Q&A, Help & Troubleshooting] matthack:
lovely but heres some fixes for errors!

Thnx for a simple guide, thought id just add some words of "wisdome/trial&fail" ;)

step 1: even if your phone says "all update" you might wanna do a "repair"/update. couse my phone said just that "all updated" but when i went to step 2 for flash 0.2.6 i got errors when running it and clicking "root" in Flash 0.2.6 saying "no adb device found...." and phone said "remount with SDcard bla bla" but then i did a repair and tried step 2 and BAM all done!!;)

step 2: see above

step 3: No problem at all following instructions.

Step 4: here i hit a brickwall did the step over and over and over again but would not install xRecovery for me. so i went to the thread for dl xRecovery from: http://xdaforums.com/showthread.php?t=859571

and heres where it gets interesting i followed the "manual install" section and fortunatly i had a old "Root Explorer.apk" on my comp that i installed becouse the only one i found on Market was latest and was a pay-for-app. so i used astro and installed my old root explorer, and then did the manual steps:

rename Xrecover.apk>

xRecovery.zip>

unzipped it as normal into a folder>

copied that whole folder onto my SDcard>

unplugged USB>

opened Root Explorer>

located the folder and clicked my way to where those 3 files are(u might wanna check the folder on your comp first so you know from start where to go)>

mark all>

copy>

clicked my way all the way back to System/bin>

activated R/W>

pasted>

exited to home screen>

rebooted as told on xRecovery thread(hitting "home button during boot up NOT HOLDING IT DOWN!">

booted to xRecovery straight away

Step 5: followed the instructions in this thread (copy/paste JIT zip to SDcard before when i tried teh auto install option for xRecover so it was all ready on there) >

and again BAM all done.

enjoy your newly rooted X10 with xRecovery/Superuser/Busybox/JIT !!!

after that its all up to you what you wanna do with it.

leave as is just for better performance or use xRecover to boot a custom rom (myself i went with kxhawkings: http://xdaforums.com/showthread.php?t=913610 rom) cant wait for it to cache and settle down to do a quadrant check, got 509 with stock...

Adding Saved .apk files(apps) you might have on you comp:

plugin a Blouetooth dongel to your comp>

Activate BT on your phone and make it visiable>

Go to your BT icon on the PC right click and "search for devices?>

Once it finds your phone follow instructions on setup>

To send a file check your phones BT settings under BT>visiable (becouse atleast with the rom im using BT is only actively showing for 120sec, might find where to set allways later?) so if its down to a few sec inactivate then active again >

Right click on your BT icon in taskbar on the PC and pick Send File> locate the .apk file you want > mark > send

To resive on your phone:

Check under your dropdown menu at top and you should see "bla bla is trying to send you file....." click that to accept and it will start the download

To install:

Same as allways use a filemanager (im using Astro) go to the file click it and install

DONE!!

This BT guide is for those running ROMs that wont open a new window from the phone on the PC which mine doesnt:confused:

hope this helps some?

remember this is my first ever android phone and ive owned it for just about 20 hrs so no ive never ever tried any of this before im the total nab, but as you can tell after some thinking i got it all sorted :D

Stay safe
