Im trying to flash map everything going good at start of the process but stopped about 10 percent saying failed to write section, paket 610. * *Tried it again and the same, *stopped at 6 percent * Saying failed to *write section paket 897?. The car is now not firing up and starter motor just keeps trying to start it with no joy. Battery is fully charged. Yellow warning lights on the dash with car on a hoist/car ramp. I have contacted mhd and he said it could be a cable issue, maybe my otg or obd cable. I can get hold of newer cables but its gonna take too long as i need the car for work. Is there any members near to the Falkirk area or anywhere in the Scottish central belt that can source or borrow me these cables to see if this is the issue. Or does someone nearby could possibly come to my house and help. Fustrating to say the least. Fuel and time at my house paid for no problem.

Check communication with ecu first. Connect good power supply unit as well. Try to reflash with winkfp. Very possible that you kill ecu during programming.

I could flash dead ecu on table but will need your cas for it. PM me if interested.

[snedanator]

How do i check communication with ecu? And im not sure on info regarding reflash with winkfp?

[litany]

You have to find someone with ista and winkfp. Is also worth to flash with nfs, but you must find correct firmware number for it.
Looks like you lost permanent voltage during flashing.

Unplug battery for 30min, let computer go into recovery mode than hook up battery charger and try again. Full write

Thanks I'll give it a go.

Na its just the same ....fail to write. .paket code.....ect. Might try new cables but im not getting my hopes up. You would think the cables would either work or not work and surely not stop working in the middle of a flash or is it still possible the cable is not compatible? .

Has anyone in the central scotland region have a d can cable i can borrow?

Are you 100% battery is charged? This sounds like classic low battery voltage preventing start.

I would happily post you my spare cable but it won't get to you till Monday earliest. You'd be better buying one, it's a worthy investment for any BMW owner.

Also, this guy had a similar problem....

MHD Flash went bad PLEASE HELP!! SOLVED http://www.e90post.com/forums/showthread.php?t=1198266

[stashtrey]

Did you try to "flash back to stock" using the MHD?

[stashtrey]

I've had it fail as well and always got the option to "recover failed write"...

Also, and this may sound like a stupid question, but are you positive the ignition is in the #2/full on position? I wasn't paying attention once and it started flashing and failed putitnf the car into error lights, wouldn't start etc. Turned out I was trying to flash in the first ignition position....

Just a couple things to check...good luck bro. I know the feeling.

yeh tried flashing back to stock, only went to 16 percent then said failed paket code ect.

[stashtrey]

Is your MHD micro USB and USB connection tight? I had a bad OTG cable that had a bad connection in the wire and would go in and out. Failed some flashes and finally figured it out. Just more ideas. Sucks bro!!

Thanks but i was hoping to have a cable tomorrow, i have now ordered 1 from cable shack
which should work and have it by Monday. Im only assuming the battery is fully charged because off motorway miles but im not sure cause i have no voltage equipment to test it.
It was on charge when i was trying to flash it and after a few hours on charge the charger said it was charged but who knows, might get a voltage meter tomorow.
As i said earlier the car turns over no problem but wont fire up so maybe the battery is ok maybe??

[mojobmw_e90]

Some cars depending on year always need a charger for flashing.

hi i never got the option to recover....
When i put the key fob in the idrive ect lights up then i press start button once then ignition lights come on....then i try to flash. Or do i need to press start button twice?

I must admit the otg to usb isnt the tightest, slightly loose tbo. I have another 2 on order to try to eliminate cable issues. ..

What i meant by starter motor trying to start is it seams to have no problem turning the car over with the starter, it just wont ignite. So it seams the battery has plenty power.

classic bricked ecu....i did remapping a few years ago (still do some diesels)

If the flash fails nearly all bmw ecus are bricked, no matter what you on the car.

The ecu will have to be removed, flashed on a bench in recovery model, (unless in the last year there is a reliable obd cable with recovery)

Its crucial on bmw ecus that you have 14v during flashing. Also using cloned flashers doesn't help. Could also be a corrupted checksum on file or just a bad file, or even bad luck

During flashing, make sure no power drains are on, like radio, heaters, interior lights etc

I don't think it's a bricked ECU as he can still get to 16%. If ECU is bricked no communication would be possible at all. Winkfp should be able to recover this ECU of comms are still possible. I'll guess we'll have to wait and see.

Ive seen many that can still get some sort of flash, even some will get to the 80%, but still fail. But yes should recover in boot mode.
