Convert (Flash) K750i into w800i
You got your K750 the other day and you were damn satisfied with the gizmo… but the story does not end here. It seems Sony didn’t ship this set with some more features that its hardware can support… The company fooled the customers by changing the K750 casing to Orange-White and named it W800i…In short, the K750 and W800 have the EXACT same motherboard… which made some nut cases out there to try out some dirty tricks!!! And the results were fruitful… K750 can easily be flashed to W800!!! The only barrier that separated K750 from a W800 was the software and that has been broken!!!!
Now… as I promised my friends, here is a step-by step easy guide to flashing your K750 to W800!

ATTENTION:
W800 firmware is encrypted as CID36. K750 is available in 2 encryptions … CID36 and CID49. Older K750s (7-8 months old) came with CID36. If your phone is new, it has to be CID49. You will find out your CID number in the tutorial itself so don’t worry about that. Just follow the instructions…
CID36 K750s can be directly flashed to W800. For CID49 K750s, we need to first convert the W800 CID36 firmware to CID49 and then flash. Things will become clearer in the tutorial itself, so no need to panic at this point!
Before flashing, back up all your data, contacts etc. etc. because your phone will be completely wiped out in the process.
Remove SIM and memory card for the entire procedure.
During flashing process, avoid touching your PC or phone or USB cable. Do not take your eyes off the screen during the entire procedure.
Do not let your phone turn ON at any point of time. Flashing takes place only when phone is switched OFF!!!!


Flash your phone in the exact same order as I have given. i.e1) Flash FS2) Customize FS3) Flash MAINReason being XS++ has a bug and flashing works this way only.
The entire process may take between 15 minutes to half- hour.
Now, I have packaged all the necessary softwares and tools that we require into one!!!
Download the whole package from here:
http://rapidshare.com/files/12706205/K750toW800.rar.html
Unpack the rar file using WinRAR.
The package includes:
XS++: This program is used to flash you phone’s firmware!!! This also lets you check your CID number!!!
Gslide: This program converts W800 CID36 firmware to CID49, to make the firmware compatible to K750 CID49 phones. CID36 users need not use this.
W800 Firmware: Your Main and File System files. Lets say these are your W800s operating system files!!!
USB Flash Driver: The driver you need to enable your phone for flashing through USB cable. Note that these drivers are NOT the same ones you get on K750 PC suite CD!
Now we are ready to flash!If your phone gets fucked up, then its not my fault! Although this process is 100% safe, but I know there are a few dumbasses out there who would want to go overboard with this. So my advice to you is do not, at any point, deviate from the instructions… just follow everything blindly. DO NOT ASK SILLY QUESTIONS.
If you have flashed before, or have used the Sony Ericsson Update Service sometime earlier, then your flash drivers may be installed so you can skip STEP1. For people who are new to flashing, this is a must!



STEP1: Installing USB Flash Driver.
Turn off your phone. Remove SIM and memory card, and re-insert battery. Do not turn ON.Inside K750toW800 folder, goto XS++ folder and open the program. now click START. While pressing and holding the ‘c’ button on your fone’s keypad, insert USB cable. Windows will detect a new hardware and ‘Install new hardware’ wizard pops up. Release the ‘c’ button. In the wizard, click ‘no, not at this time’ and next. Choose to install from a specified location and click next. Under ‘search for the best drivers to install’, check ‘include this location in the search’. Under ‘browse’, choose the path to the unpacked folder you downloaded and select the folder USB Flash Driver. Now click next and let the windows install the driver.After installing the driver, close XS++ and disconnect phone and turn it off in case it has switched on. Remove battery for 2 seconds and re-insert it (to refresh your phone).Now your phone is ready to be flashed. But first let us check your CID number.
Again open XS++, click START, and insert cable while pressing ‘c’ the same way as before. Your fone gets detected and on the left side of the screen, you get the detailed info of your phone including the EROM CID number.
If you have CID 36, then skip STEP2 and go directly to STEP3. Do not close XS++ or unplug your fone.

STEP2:
Now, you know you have a CID49. So our job is to convert the CID36 firmware to CID49.Open Gslide. for flashfile, click ‘…’ and select the file named ‘W800_R1BC002_MAIN_EU_EMEA.bin’ inside the W800 Firmware folder.Inside ‘output’ type in the path… C:\MAINFLASH.binNow click ‘Process’. After sliding process is completed, again click ‘…’ for flashfile and select file ‘W800_R1BC002_FS_EMEA6.bin’ inside the same folder. Under output type in C:\FSFLASH.bin and hit process. Close the whole program after sliding completes.
Now you have generated 2 files in C:\ drive using Gslide. MAINFLASH.bin and FSFLASH.bin

STEP3: Flashing FS.
For CID36: Your phone is already detected by XS++. Under Select Firmware, check Flash File System, and then click ’…’ , now select the file ‘W800_R1BC002_FS_EMEA6.bin’ inside W800 Firmware folder. Hit flash… the flashing process is now initiated. After completion of 291 blocks, it will say either ‘done flashing’ or hang at ‘finishing flash’. Don’t worry about it. Close the program and unplug phone. Again take-out and reinsert battery to refresh. Goto STEP4.

For CID49: Inside XS++, Under Select Firmware, check Flash File System, and then click ’…’ , now select the file ‘FSFLASH.bin’ in the C:\ drive which we generated from Gslide. Hit flash to start flashing process. After completion of 291 blocks, it will say either ‘done flashing’ or hang at ‘finishing flash’. Don’t worry about it. Close the program and unplug phone. Again take-out and reinsert battery to refresh.

STEP4: Customizing FS.
Common for CID36 and CID49: Again open XS++ and connect the phone same way as we did before. Now check Customize File System and then select phone model ‘W800’, select CDA and region ‘EMEA_6(CDA102430/6)’. Hit Flash. It will ask you whether you want to use ‘breakin’ or ‘brute-force’. Click ‘yes’ for breakin and strictly follow instructions on the left side of the screen. It will ask you to connect and re-connect phone 2-3 times by press and hold ‘c’ method. Do not panic at any point here, just follow the instructions carefully on the left. At the point when it says ‘FS activation’, wait for 3 minutes. After completion, close XS++ and unplug fone. Refresh by re-inserting battery.


STEP5: Flashing MAIN.
For CID36: Open XS++ and again connect your phone the same way. Under Select Firmware, check Flash Main, and then click ’…’ , now select the file ‘W800_R1BC002_MAIN_EU_EMEA.bin’ inside W800 Firmware folder. Hit flash… the flashing process is now initiated. After completion of 291 blocks, it will say either ‘done flashing’ or hang at ‘finishing flash’. Unplug your phone and close XS++.
For CID49: Open XS++ and again connect your phone the same way. Under Select Firmware, check Flash Main, and then click ’…’ , now select the file ‘MAINFLASH.bin’ in the C:\ drive which we generated from Gslide. Hit flash… the flashing process is now initiated. After completion of 291 blocks, it will say either ‘done flashing’ or hang at ‘finishing flash’. Unplug your phone and close XS++.


STEP6:
Now, insert your SIM and memory card and turn on the phone, wait for sometime as the phone takes time loading from a brand new firmware.
KABOOM!!! You have a brand new W800!!! Enjoy the cool new WALKMAN startup!
