Can't unlock K700i, get 305011 & 000409 codes SEMCTOOL 3.3

[New4now]

Hello all

I have read a lot on this forum but can't understand a lot of the terms used, so thought maybe I'll just ask & see if any body can assist, please.

Very new to unlocking, just wanted to unlock my K700i, after local shop said they don't have the cable, so tried to DIY it.

Got a PC USB cable for unlocking from ebay - it has label that says SETOOL on it and has a connector like phone jack (RJ45?) into a small box and then a connector that plugs into the SE K700i phone, very similar to a data transfer cable that I use to transfer photos etc between phone and PC. But this unlock cable has this phone jack connector and larger box and cost a lot more, I assume it's a Sphere GSM Fighter as that's what one of the drivers seems to be for it.

When I use it with any web-available unlock software, the phone comes on when I run the software, but the error message on the software says nothing much happened. :confused: Been trying for 12 hours now. Pretty frustrated.

Cable seller told me to use Semctool v 3.3 craxored which I have tried. Phone comes on then goes off when I use the software, get this on program error message:

SEMCTOOL I got:
Switch phone ON
Get phone info
ERROR: 305011

Sometimes, I get error 000409 instead.

On SEMCTOOL I got:
Bypass boot authority
Phone OTP CID: 226
Load data to phone
ERROR: Unsuported CID

SONICS I got:
power it ON now!
Chip Id: 0x1777
CID detected: 62370

No idea what these codes mean! Was told I can only read codes and then do the manual unlock by <**< method of input (my ECK/ESL is only one with padlock down).

Anyway I get those error messages whichever I try, Read or Clear.

Also I wonder if I can use the DSS25 docking desk cable unit for unlocking?

If I can't cable unlock then apart from paying a lot to the network to unlock me, anyone recommend a good value unlock service or free code generator. I understand I shouldn't give my IMEI out to avoid cloning, though.

Sorry for long post, just pretty confused, new to this, only basic knowledge!

Thanks for any help.
