Xperia X8 update 2.1 Discussion thread

---

As you know update is already out. Here is information how to change your customization code so you can update:

1. You need your phone to be rooted. I use superoneclick 1.5.0. for me it works best. Newest versions do not work correctly at my X8. The attached archive X8win is the superonelick 1.5.0. You should enable usb debugging (settings->applications-development) and connect the phone to your pc. If you do not have drivers for the debug mode you can use the ones from the "X8 drivers" archive which i have also attached. After you have the drivers installed ,usb debug enabled and phone connected start superoneclick.exe and press root. You may need to wait 5 or even 10 minutes for it to complete. Wait until you see "Your device is rooted" popup.

2. Install root explorer. I have also attached it. Start root explorer. Open the "system" folder. In the upper right corner of root explorer you will see "Mount R/W" button. Press it. Now go to the build.prop file. Long press on it and select "Open in text editor". You should edit the following items:

ro.product.name=E15i_XXXX-XXXX where XXXX-XXXX is the customization code. For example mine is 1241-3708 but there is still no update for it.

ro.build.fingerprint=SEMC/E15i_XXXX-XXXX/sonyEricssonE15i/

ro.semc.version.cust=XXXX-XXXX

You should replace XXXX-XXXX with the desired customization code for all the lines listed above.

When ready press the menu button (left) while still in the text editor and press save.

3. VERY IMPORTANT - REBOOT YOUR PHONE.
4. After reboot check for update with Update service or PC Companion and it should find it.

If you edit your build.prop on your pc and return it back to the phone you should correct it's permissions so that it can be read by user, group and others and written by group using root explorer.

You can also see the codes which have the update at the sony ericsson product blog:

Here is how to check your customization code:

1. Lock the screen of your phone. Press the menu button (left button) so that the screen is lit but still locked.
2. Press the home (central button) and back (right button) in following sequence:

home-back-back-home-back-home-home-back

Try several times if you can not do it the first time. when successful secret menu will appear. Go to Service info->Software info and find "customization version"
It should be something like 1241-3708_R3A (this is my code, your will be different but the same format).


CURRENTLY THEE IS NO WORKING ROOT FOR 2.1. Superoneclick and z4root do not work.

i am wondering since x10 mini and x8 are basically the same can we flash x8 with x10 mini 2.1 rom ?i sent Bin4ry a message asking and waiting for response.

p.s x8 was supposed to ship with 2.1 or 2.1 two weeks after release.what are you doing SE?

I don't think that we will be able to use X10 mini image to flash x8 because the screen size and resolution are different and also the camera. Of course i will be very happy if Bin4ry proves me wrong and it is possible. X8 with this price is very attractive phone but SE should quickly update it to 2.1 so it sells even better.

we certainly need the update for x8, its a good phone, pitty about the OS at the moment limiting its potentials

Cooking custom rom for X8

---

Greetings all,
I will post these tips for those willing to repeat the success of custom roms on the X10i.

You can find a few X10i forums where they have cooked cyanogen rom.
To cook the new 2.1/2.2 rom, use standard kitchen from this link :
Cooker guide

You can start with HTC Legend template, but than modifications to .mk file are required.
Finally all the binary libs and custom files should be added to the rom, than cook it.
Once cooked (took 50min on dual P4-3Ghz machine), you get update.zip, system.img and boot.img files.
I've been playing with .zip files and noticed they don't have file permissions kept.
So the one to use is system.img, you can extract files from it with unyaffs tool (google it, its free).
If you extract files under unix (Linux/MacOS) file permissions will be kept and files are ready to be copied to the phone.
It's quite annoying to flash phone every time you made a mistake, so first make sure you prepare your X8 to boot from sdcard.

To boot from sdcard, we need to hijack the boot process from sony and mount our own /system and /data partitions.
After booting kernel, X8 runs the init.rc script that loads up Android.
Before the start, it checks if phone is off and plugged to charge (you probably saw this feature when phone is switched off on charge and screen shows battery animation)

This check is called chargemon, and its /system/bin/chargemon.
We can replace this file with a script.
Prepare the card like this :

1. FAT partition (fat16/fat32), 100MB or more
2. /system partition EXT2, 512MB
3. /data partition EXT2, 512MB

Once partitioning is done, mount the 2nd and 3rd partition on the phone and copy files over :

mkdir /data/local/tmp/1
mount -t ext2 /dev/block/mmcblk0p2 /data/local/tmp/1
busybox cp -rp /system/* /data/local/tmp/1/
umount /data/local/tmp/1
mount -t ext2 /dev/block/mmcblk0p3 /data/local/tmp/1
busybox cp -rp /data/* /data/local/tmp/1/
umount /data/local/tmp/1

This script will make phone mount /system and /data partitions from the sdcard :
chargemon:
#!/system/bin/sh

# Mount system and data @SD card
/system/bin/e2fsck -y /dev/block/mmcblk0p3
/system/bin/mount -t ext2 -o rw,noatime,nodiratime,nosuid,nodev /dev/block/mmcblk0p3 /data
/system/bin/e2fsck -y /dev/block/mmcblk0p2
/system/bin/mount -t ext2 -o rw,noatime,nodiratime /dev/block/mmcblk0p2 /system

create file chargemon, chmod it 755 and put in /system/bin/
You should also put e2fsck from CM Legend rom in /system/bin/ and ext2 libs that it needs into /system/lib/, or put a # before checks if you don't care

If sdcard is not present, phone will boot in normal way, and with sdcard inside you can boot your custom rom or modified standard system (for example with lots of installed apps and custom framework/fonts/...)


I hope this helps someone with more time, as I don't have much experience cooking roms.

Summary
1. Kernel can't be changed until bootloader is hacked, so we have to stick with 2.6.29.
2. Boot process can be hijacked by modifying files called from init.rc script.
3. We can boot anything from the sdcard


P.S. if you have little idea what this is about, better wait and don't bother.

I tried to get information from SE online chat support but without success. I asked about the date when it will be available, will the 16 million colors be enabled and if there will be froyo for it but for all my questions i received answers that they do not have such information. So currently nothing in particular for X8 unfortunately.

sadly Bi4ry replied it's not possible.

black xperia x8 running 2.1 so it's ready and iam sure it is) why not roll it

may be they want to give x10/mini users a premium feel

sorry for wrong link (corrected now)

Here are some good news - firmware 2.0.A.0.504 was approved in ptcrb at 05.11 so i think that we are pretty close to the final update now.Let's hope that in maximum 2 weeks we will get it.

yeaaaaaaah 2.0.A.0.504 is the released sw version for both x10 and x10 mini/pro so this is the release version for x8 ,it's absolutely ready.i bet in a matter of days because this is the final version no more testing . they only need to upload it to the servers (for unbranded phones of course).crossing fingers
