K550i@W610i: Stone Turns Into Gold
Hi, it's a good news for you all. Now you can crossflash K550i to W610i. It's no joke, so many sites has this discussion for example: se-nse.net (modding heaven!), esato.com, and for bahasa Indonesia you can go to forumponsel.com especially SE modding thread. You can also check youtube.com and write k550i@w610i as the keywords.
BACKGROUND
First question is, how can it be possible? Simple answer: they are twins! Both have the same hardware but different exterior. Remember also K750i-W800i. The history happen again with K550i-W610i. Since both are twins, we can crossflash the firmware.
WARNING!
Modding/crossflashing will void your warranty. You can brick/damage your phone. Do this at your own risk!
HOW TO DO?
You'll need these stuff first:
1. USBFlashDriver (it's not the same as your phone usb driver).
2. XS++ v2.2 or XS++ v3.1. Check your CID first with this. If you have CID 52 Red, go on this tutorial. If your CID is 51 Red, convert it with XS++ before flashing.
3. FS + MAIN W610i
If you live in asia-pacific, get the APAC version for FS. For example: W610_R6BC002_MAIN_GENERIC_NA_RED52.zip and W610_R6BC002_FS_APAC_RED52.zip
If you live in europe, get the EMEA version for FS. For example: W610_R6BC002_MAIN_GENERIC_NA_RED52.zip and W610_R6BC002_FS_EMEA_RED52.zip
4. Custom pack
If u live in asia-pacific, download W610_CDA102568_202_R2A_GENERIC_APAC.zip. This is for phone language. In APAC you can get bahasa Indonesia, Tagalog, Malay, Vietnam, China, and of course English.
Those file can be downloaded in:

STEPS (sample pictures can be seen from
http://blog.se-ven.net/masterbiji/2007/10/01/k61xw660/)
1. Remove battery then put it back (phone is off). Press C button and connect it to your data cable that's connected already to your usb motherboard/laptop port. Windows will detect new hardware. Search your USBFlashDriver directory. After that, remove your phone from data cable, remove battery and put it back.
2. Extract XS++ to your computer and make directory
In own_custpack, fill this with your custom pack.
3. Start XS++. Press Connect. You'll have 30 seconds to connect your phone with data cable. XS++ will try to recognize your phone like phone model, IMEI, CID, and Color. If your phone on after connect to XS++, maybe your USBFlashDriver is not installed correctly. Repeat step 1.
4. Watch your EROM CID + color. It must show CID52 Red. If not, upgrade first with XS++ otherwise XS++ and your computer will crash. Color is also important. If your phone is brown, forget this tutorial and live happily with your original K550i.
5. Click GDFS button
6. Back up your GDFS for your own safety
7. Remove the phone from data cable, remove battery and put it back. Don't turn it on. Connect again your phone to XS++
8. Click the box in front of Flash Main Firmware, Flash File System, and Customize File System. Click '...' button and find your MAIN and File System firmware. In Customize File System, choose Own custpack. CDA and Region is also \own_custpack
9. Click Flash. Wait until XS++ finish the job. It will says, "Disconnected... Unplug the phone". Remove your phone from XS++, remove battery and put it back. Now turn on your phone and yipee..! you have a W610i inside, K550i outside.
WHAT'S NEW?
Ho ho, now you have Walkman V.2, MegaBass, and Flash menu. Don't forget to spend your extra cash to buy larger memory stick and earphone HPM-70.
Because computer will not recognize your phone, you have to download W610i usbdriver from sonyericsson.com. Happy modding everyone!
