Landrover KVM BJ32 dflash and eee help needed.

[thayer201]

hey guys,

im getting myself in a right pickle with this one.. and its driving me insane.

so i have

landrover kvm bj32
MC9S12XET256 2M25J
unsecured

So read dflash xprog v5.5.5 which i dont normally have issue with(on other mcu), this time i got the errror partion corrupt..
so i went ahead and backed up full 32kb dflash, then went and backed up eee full 4kb,etc
then again went in a read the correct size that was needed for mart tool, loaded mart tool write key data and had 2 files.... ok

since my xprog was giving out errors i decided to write back the info with upa, as sure my partion wasnt corrupt data looked good..

but not before i swaped over to upa i used xprog to erase dflash partion and eee... now i had to input manualy so me without thinking.

went in dflash chose 32kb dflash and eee 0 partion and erased..........

right so i thought ive got back up full of dflash and eee so what to do...

ive got 2 files from mart tool dflash and eee with key info to write back but im having a hard time doing so.

i tryed erasing agin and setting dflash 0 and eee to 4096 but i cant write dflash and eee or viceverser one or the other

using xprog and upa...

am i missing sometihing here with partion.... ive tryed everything. cant write both?? obviously not the right things as i wouldnt be here...

upload files also...

go easy on me

Ok so solved partioned with upa write with xprog was only way.

that situation kvm is repaired key unlocks on remote but non start..

Orginally came with non start no remote no start..

No comms to anything other than

IPC
BCM - bcm has fault b102b-67
Check actual values no keys stored 0
Cant get access to kvm via diagnostics.

Tryed force ignition but switches off to quick to pluv anything in..

What are my option?

Best way to go..


SOLVED......... managed to force ignition on with obdstar x300 and swap for sdd then reconfigured bcm, then done restore keys with obdstar x300 (as sdd wwouldnt do it- failed ignition on) then went back in and had comms to rest of modules ran target id write, car starts remote works...

At start reason for bricked kvm and data corrupt in bcm was due to key programming gone wrong due to can blockers. (Not me) was a mess.... other keys done with x300
