Well, did ask/mask update on e65 and system is gone now. Programming ended with an error Ref. 8352. Black screen, no navi/audio/phone etc...Though autohex is safe but turns out its not that safe on most system. How can i recover it??

the problem is no autohex, are the same problem in all bmw dealers when you try to update ccc radio . this module is some cases it doesnt supor the new update , example when last updated for radio was many years ago like 2008 , when you trying to updade to last year the radio suffers damage.. the same problem is for CAS module when the last updated is too old .
the problem is from facctory

Will have to go back to bmw standard tools and try to recover it with winkfp. Not happy...

did you not get a bit ETA when tried to program? as i know ASK is on MOST protocol so on CAN shoul take a long time to finish updating. never a good idea to update modules that are updated over MOST regularly, i lost a E90 CIC that way...

14mins.

car is done now , problem is Autohex not have MOST connection for MOST module , problem sorted with ISTA P

Thanks to cardiagcom. Yes, be very careful on most system with autohex. The programming most system option should not be there...

If you want to program an Ecu in MOSt network, you should be aware about the dependency among those Ecus in the same network, when an Ecu is erased, other one (at least partially) is erased too . This means, you have to flash the MOST Ecus group in a correct sequence. Or you will get the error 8352 which means Ecu is still in boot mode.
Autohex II is safe if you know what you are doing.
To solve this issue, you can use ISTA-P which will flash all Ecus in this group in the correct sequence.

Hi
How you flashing MOST modules via Autohex for example CIC, MMI, can you explane for other users please?

Ok, but how we can know what is correct sequence? Radio first? navi first? tv first? I will defo avoid using autohex on most system, is that the soution?

The trick is to know which Ecu should be updated before the other. Autohex II does not show the sequence but it can be calculated from the FA.
Unfortunately there is no fixed sequence because this differs from a car configuration to another.
If you have to do this update by Autohex II and Autohex II has failed, you need to send us the log file, from there we can conclude the update sequence.
By the way: MOST network Ecus update is always risky in E series, no matter if you used the MOST cable or not, just check other BMW forums to realise that it is better to not update such Ecus unless if you are forced too.

I never update MOST ECUs (even with most connector) except if customer signs a waiver that I am not responsible :-))). Makes the life a bit easier.

This is a very wise method

Ok. I'm happy with the respond and explanation. Thank You

True ! even with ISTA-P and certified ICOM + MOST plug you most likely lose the MULF ECU when updating your CIC/CCC

I have genuine ICOM Next and MOST

I have done a software update on CCC only for it to brick
Telephone modules are very common to brick also

Even when you do update the CCC, often premium voice is an issue. you need to pay and raise a ticket with AOS to get the certification to reinstall it

I just avoid doing the CCC or CIC unless all is lost.

Yes it can be received buts its more work that often isn't needed.

On RAD2 I've updated with autohex and its bricked. reapply update with autohex and it goes through
