I guarantee there is a CRC check of some form. It would be suicide not to. I would expect the downloads are compressed as well and those are implicitly CRC'd.
Agree. The whole damn car runs on software. I would think that there are massive checks and balances involved in the process. I work for a software company and we just don’t half @“& updates.
What do you classify as special characters? I have an iPhone X running iOS 12.4.1 and LR AWD and don't have the crashing. I have contacts with the following: - , ' , / and some with emoji's in the name. I didn't look to see what the emoji's register as in the contacts list in the car. I can. I only tried this once and toggled from first name to last and back to first name. From the video, from reddit, it happens immediately so not sure.
I live in Denver and have had no issue with the regen. Once the battery warms up it's normal as it was since the hold option came available. I only toggle to low regen when it's icy and keep on on standard otherwise.
My phone contact list has # and @ in several contacts and my phone is an Android based one. Some times I can toggle back and forth with no issues but not usually more than like 3 toggles. More often though, it crashes on the first time. So far, this is what I know: Android and Apple phones have had the crashing but not everyone has it. I have not seen a report of an Android phone without # or @ in the contact list causing the crashes. Yours is the first Apple phone with "special characters" in the contact list and since it isn't crashing, I guess we can rule that out. The only other thing that I can think of left is that it is caused by an android phone with special characters in the contact list. Once someone reports that that works okay also, then I can't think of any other obvious cause.
My battery never seems to warm up even on a 40 degree day and after driving on the freeway for 20 miles so I rarely get full regen unless I precondition the car first. When your regen is limited, do you feel like it is variable or inconsistent in the braking force and rate of braking force increase? I feel like mine is but I guess my perception might just be skewed after driving a BMW i3 for awhile which has great regen.
Surely the part where this happens involves a CRC or similar check?
3. perform integrity checking of the resultant image (obviously failure at an of the steps results in restart from 1)
It would be completely irresponsible for Tesla to design the car such that software is downloaded over the internet and then directly flashed to the components without checking to make sure no corruption or data loss occurred. My car always downloads new software pretty quickly then sits on 100% for like 10 minutes. I can only imagine that that is the point in the process where the download's integrity is being confirmed.

we don't know what 'often' means, but I assure you, wifi firmware fixes from ublox (etc) come every so often and its a reality.
(ob disc: I used to do this in a previous job; worked on car gateway stuff and dealt with wifi, lte, gps issues on a daily basis).
trust me, failure in the middle of an install SHOULD abort the install. dependancy hell is hell for a reason

when its a bankA/bankB flash config, YES, YOU DO!
this is not arguable. I can tell you've never done this for a living. those of us who have, know what we're talking about.
It feels consistent that it's rolling more like an ICE vehicle when I left of the pedal and I use the brake more but it starts coming on more and more as it warms up. To your point I've driven for close to an hour before I lost all the regen limited dots in high 30's / low 40's.

IPhone 7 iOS 13.3, 50 or so contacts, reboot on sort. Only normal characters in the names.
Just did some testing. I created a new contact (First Name: Tesla #, Last Name: Testing @) and I made sure I was not connected to the car while sitting in my living room. Went out and went through some other menu items first then contacts and scrolled through and found that my contacts that have emoji's actually display in the car contacts. Found the Tesla Test name and it displayed the # and @ characters as well. Scrolled all the way up and changed the sort multiple times and nothing. Closed the contacts went through some driving menu items and went back to contacts and changed the sort right away and no restart / crash.

HW3 is the driving computer- the reboots folks are reporting (and what I'd expect is handling phone contact stuff) is the media computer.... so HW 2.5 vs 3 shouldn't matter here.
We know that Tesla just dealt with a WiFi firmware update on the S&X that was the result of a security vulnerability that was identified and reported. So it seems reasonable that there might be a similar one for the Model 3.
Thanks for doing that! So we can rule that out then. Do you have Android or Apple?
Edit: I'm blind. Saw you have an Apple phone up above. Now we just need someone with an Android phone to do the exact thing and confirm that it doesn't cause the crashing. Only thing pointing to special characters not being the cause is the few people saying they don't have any non-alphabetical characters in their contact list and they still have the resets. So maybe back to a number of contacts thing? But then again, ~50 contacts isn't really that many so that doesn't make sense. I give up. Haha.

just went with a friend to pickup his new performance s and it had the .7 software on it however it was also busy downloading a new and very large map update. anyone else get a map update recently or with .7 ? he incidentally has the new hw3 and the visualizations fsd demo. maybe this uses a new map?
