Could do with some feed back on this peeps

The Problem:

Z800 that's locked to 3 (Three)

After a bit of reading and head scratching...

...have I got my facts right????

Are these Fact or Fiction:


  1. Can not use SEUS as phone is locked to 3 (Three) - So no update that way
  2. No need to UNLOCK in order to DEBRAND - So can stays on 3 (Three) but still get debranded
  3. DaVinci is the best way to go to unlock (if needed) and debrand
  4. No Special cable needed to DEBRAND - So can use the standard USB cable - T28 connector
  5. Need USB-FTDI chip based self powered cable sets for unlocking Z800 - with T28 standard connector (UC-10 Cruiser USB-FTDI 4 in 1 cable)
  6. Can use V800 USB Flash driver http://www.sonyericsson.com/spg.jsp?cc=gb&lc=en&ver=4000&template=ps1_1_3_2_1&zone=ps&lm=p
  7. Z800 R1AB014 EU4: EN DA SV NO is the correct firmware update for English & Swedish
    Code:

    Z800 R1AB014 EU4: EN DA SV NO
    maindvt=Z800i_MAIN_EMEA_EU_R1AB014_CID36.DVT
    fsdvt=Z800i_FS_EUROPE4_w26_R1AB014_CID36.DVT


  8. CDA102337/12 - Europe4 is the corrct CDA for firmware selected
  9. Credit can be bought from DaVinci and 1 credit to unlock 1 credit to debrand
  10. I could phone 3 (Three) customer support to get the unlock code (could I???)




I know these type of questions are plastered all over the place with answers...

...but...

...I'm a wimp

I don't mind deleting this topic after the feed back

just to keep the place tidy

I slightly worried about that Submit button...

...It looks bigger than normal and with horns

do you need to do cda flash in order to debrand it ?
Edit: i kind of answered my own question, yes i do coz the cda on my phones different it also said something in the phone about customization so i assume that the cda is like the customization file for the phone, correct me if im wrong

yeah you could phone three for the unlock code except they charge you AU$150 unless youve had the phone for a year

original usb cable checks out with the test cid/cable

$$150

Looks like we heading the right way...

No need to unlock if keeping the 3 SIM

So that save on the cost of the Cruiser cable (or Like).

The FS, MAIN and CDA (PM was CAD sorry, meant CDA) seem OK...

DaVinci looks the best option beens DVT files are save to local disk already

Just a mater of Credit...

...if the flash goes wrong!!!

Oh! woh is me!!!!

a-ha! ~ a DaVinci forum with a FAQ JOY
