I have a avh-nex4600 and it’s stuck in boot loop  I can’t open the face to insert the SD card. HELP‼️

Same problem here with my W4660NEX

So I had the same corrupted SD card issues that everyone described in my 4400. I loaded a new card, swapped it out and it worked perfectly again.

My buddy has a 4500 that seemed to do the same thing. I followed the same process and swapped out the SD card but got a different result. The unit turns on, displays the NEX screen, proceeds to the Pioneer loading screen for a few seconds and then just turns off. It didn't boot loop, just shut down. I disconnected the power and tried a few more times with the same result. 

Any thoughts ? Appreciate in advance. 

I had some similar issues on a 4500, I had burnt an image using Disc Imager on a Windows 8.1 laptop. After about a hour of working fine it started rebooting very frequently. I then burnt another sd using a Linux computer using the dd command and have not had any problems at all. I did also use a 16 gb, San Disk sd card this time.

Thanks for the input. Do you remember which software version you burnt that ended up working?

I used the 4400 software that I got from here, then I got the 4500 conf.sysd file from here also, I added it to the original 4400 conf.sysd file then I deleted all the other stereo’s config info so no matter what it would take the 4500 info since it was the only one there. Then I used Linux Mint on an old laptop using the “dd” command to burn the image to a Sandisk 16gb card. Honestly I think the Disk Imager from Windows was the big problem. 

My 4400 got stuck in the boot loop a few months back and I used the image to write to a new SD card and everything is working great. I had to change the battery in my car and the 4400 is now asking for a password to unlock the head unit and is giving the password hint of “pinball6”. I didn’t set a new password after reimaging so I’m guessing this is the password that is already included in the image file. Does anyone know what the password is? Sorry if this is covered somewhere else and I missed it. 

I have a AVH-4200....initially I could hear the radio with a blank screen ...then I had the bright idea to reset the unit..... now I have the  continuous loop of DEATH ! according to Pioneer I should have firmware v1.07, can I used this firmware to get the unit running or do I need to search for the correct one ....old geezer here looking for help.....Thanks in advance .

Followed the instructions to a tee. Removed the old SD card and replaced with a 32G card loaded using the instruction video. Weird thing was that my computer couldn’t read the old SD card but showed the newly imaged SD card as having like seven or so partitions. Tested head unit and it went to the loading screen then instantly went dead. I wasn’t getting the five minutes worth of snow on the screen anymore. This is not worth my time anymore. I’m pissed and want my sounds back. Just gonna buy a new head unit but never again gonna buy a pioneer.

You can’t read the old card because the head unit password protects it making it unreadable unless you know the code. There are a bunch of different partitions on the software, 7 could be right. Which unit do you have, the 4400 ?

Yup the 4400. Symptoms were just like the video showed. Was pretty sure I was gonna fix it. Right now I’m just aggravated…thanks for your quick response to my post though.

It was just luck. I happened to be looking when you posted. Did you use Windows to burn the image to the sd card ? I found that to be an issue for me.

Yup used windows. Doesn’t matter now though bought a new deck today. Wasn’t gonna get another pioneer but doing so will allow me to use the existing plug configurations. AVH 4660. No CD player on this one but oh well. I got a nice 4400 I’m gonna turn into a paper weight…Cheers

They fetch a pretty penny on eBay since most ppl know about the bootloop fix.

I have this issue on my head unit AHV-Z9250BT.

Does anyone try this seller on ebay?

AVH2AVIC - Pioneer AVH-Z9200DAB AVH-Z9200BT AVH-Z9250BT update to AVIC - SD card | eBay

They claim to upgrade the software for AVH-Z9250BT to AVIC model which has build-in NAV as well.

 

Or if you can share the firmware for AVH-Z9250BT will be appreciated

 

Thanks,

Ron 

Have you find the firmware or image for AVH-Z9250BT? 

I got same problem.

your help is much appreciate.

So.. I tried this solution for my AVH-Z9250BT. It worked but unfortunately the software is for the AVH-W4400NEX. It’s a temporary fix which makes the head unit work but I am unable to use wireless mirroring or the Android Auto. Is there anyone who has the “.img” file for the AVH-Z9250BT?

 

would really help.

Did you fix this issue?

I got same problem.

Hello All,

   I started having issues with my AVH-W4500NEX on Monday and found this thread today. Where can I download the newest firmware from to fix this bootloop issue? TIA

I also have another issue with this HU. The front face does not open up and slide out when you press the button. any ideas? It never has since new.

Robert.

First off, thanks so much for this thread! Saved me from having a $800 paper weight. My 4400nex had the "contact pioneer software error" screen

I dremeled out the front, and put in a new SD card with the 1.02 firmware. Everything works great, except for one problem. I have to have the manually drag the faceplate part way open for it to work. If it's closed it shows the screen showing me how to detach the faceplate, and if I hit the eject button it cracks it slightly and then shows me a pic of a CD being inserted. If I then grab it and manually pry it open a bit more, then it works as normal.

I'm not sure if maybe I somehow messed up a sensor when prying it open to dremel out the front, or if it's an issue with the firmware not being quite right. I've been searching all over and haven't seen anyone ever have this issue before, any suggestions?

Also, I did want to report that I have android auto on a pixel 3 with android version 12, and everything besides that issue works fine (saw a bunch of posts about android 11 not working with firmware 1.02, so apparently its fixed in 12)

Cheers!

Hello Everyone,

Thank you for this helpful thread. Ive got a 3 year old 4400NEX that crashes A LOT with pixelating screens, continuous boot loops, and a lot of frustration. While it never actually shows the software error screen I do believe my issues is indicative of the failing SD card. I've already got the files ready to go on a new SD card.

I'd like to carve out a new SD card slot notch without removing the unit from the dash. Any last tips so I dont accidentally hit a ribbon? I was going to draw a template based on the cuts others have made in this thread, and was thinking of trying to use the cutting wheel on my Dremel to make shallow cuts. I dont believe Ive got the metal engraver attachment (only have the one meant for wood).

Sounds scary to me. 
It was so easy to remove the unit from my truck, remove the face plate from the unit, drill the hole. It took less than an hour to do it all, probably closer to half an hour and had no idea what I was doing. My advice would be to reconsider. 

I do agree that's it's not optimal to go in blind when cutting, but my dash removal is a few hour job, and I'm encouraged by the fact that at least 3 people in this thread have done the cuts without removing the headunit.

Good luck, go slow, be careful. 
I don’t remember if there is a cable there. 
Here is my cut out. 

All of your pictures and others in this thread have been helpful

My goal is to follow the method posted by @C4pt4inMatt

@11thour posted the cutout that actually shows where the ribbon is beneath the internal SD slot. I know there's very little room for error.

Now that is a cut out. Wow. 
I hadn’t seen that photo. 
Good Luck. 

Thanks. All done! My dremel cut was successful thanks to the tips in this thread.
