If I can't find an image of the AVH-4400NEX Software, can I buy another unit and copy the software from that one?

Same question as briceyboo.

My unit is stuck in boot loop and I wouldn't be able to get into the firmware update menu per the instructions on Pioneers website.

Is there a write up on ripping the software image from a working unit?

Thanks in advance.

Same problem, software error screen. Does anybody have the SD image or software for the  internal  SD replacement for the 4400nex? Thanks In advance.

Did anyone find the image/software for this unit? If so please, send me a message or post on this thread. Thanks

I am also trying to find the image file for the AVH-W4400NEX, however even if I find it, I tried to access the SD Card (if it ever exists) and it is insanely difficult it find it. There are a bunch of screws, and if you loose one of them, you are screwed. Has anyone got to find the SD card on this unit?

The location of the SD card with the image is behind the faceplate. Had to remove 6 Phillips screws and manually pull out the eject mechanism. Have to remove the ribbon cable to the board that connects to the faceplate as well.

its right below the accessible SD card slot.

now to find an image...

Bux, were you able to find the image? I have this model as well.

Looks like i have the same issue

anyone got this fixed?

as a IT guy iam pretty handy with soft and firmware anyone please help me out 

I managed to image a new SD card. send me a pm if you also need the image.

My unit is working again!

Mine just died on the ride home.  Can I please get a link to the image ?  Do I just have to take the unit out and take the face plate out ? 

What size SD card do I need ?

Thank you

For what it's worth I just repaired mine.  Followed the instructions from the poster Bux.  Thank you Bux!!!  Not difficult at all.  I could not find an image on the net for free so I purchased one from ebay.  I could live with the $35 cost as opposed to the $200 plus Pioneer wanted to charge.  

So I have the 4400nex that had the same system error and then my screen would flicker on and off. 

I purchased this sd card

Was hoping that I didn’t have to remove the radio, but I guess I do.

Will this downloaded on a SD card work?

My first posting...found you guys via Google, while trying to troubleshoot my AVH440..

My unit has been doing a few odd things...it’s 2 years old.  The first oddity is a tendency to change screens from what I left it last time...it begins playing, then there’s a period of several seconds where there’s no sound, then 80% of the time, it then plays (but the screen has changed)...the other 20% of the time, it will say that it can’t find my phone (iPhoneX, IOS 14.2)....

Sometimes, when it does this, I can go to “Bluetooth Audio”, and get it to play music, but Apple CarPlay isn’t connected....

I have gotten the “Software Error” message once, but that was several weeks ago..it’s not come back.

Is this a potential symptom of a failing SD card, or is there something else going on?

Hi,

I followed the instructions, got a 16GB SDRAM, formatted with FAT32, extracted firmware from the download, works great but I can't get any sound/audio out?  everything seems to be working, boots up, shows Firmware 1.02, connected to my phone, i can play Amazon Music, it shows progress on screen, but no sound out.  Any clues?

Thanks,

Eli

Bad image or wrong radio

Thanks Bonee, so if i'm able to see the firmware version on the radio, does it mean it's at least the right image for the radio?

No

thanks again, i just tried a second image, downloaded from How to fix for AVH-W4400NEX boot loop - NEX Series - AVIC411.com , I have an AVH-W4400NEX, and it did the same thing.  Also noticed that the HD radio is not showing any stations or ability to tune one, so i do think i may have an image issue.  I am using Balena Etcher to burn the image and it goes well.  puzzled, any suggestions?

Hey all. Just wanted to let you know in case anyone else has the same issue as me. After replacing my crapped out internal sd card on my pioneer nex4400 with a new sd card using the disk image I found on here containing firmware 1.02, my Pixel 3xl would no longer work with android auto wireless. After some testing, I figured out that an older phone that was still on android 10 would work with 1.02 in wireless mode, but something about android 11 and firmware 1.02 don't play well together in this unit. So after a few months of desperately trying all kinds of troubleshooting, I finally settled on finding some way to downgrade my firmware on my nex4400 to 1.01 where it was working flawlessly with android 11. Unfortunately, this is not an easy task as you need to once again open up the unit and replace the internal card in order to downgrade. Fortunately, I had taken the easy way out when I took it apart the first time and just dremeled out a rectangular hole in the plastic covering the internal card so that all I have to do now to get at it is hit the screen eject rather than taking my whole dashboard apart. So the really challenging part was finding an internal disk image to use. Today I finally struck gold exchanging a few messages with one of those russian ebay sellers who sell the replacement internal cards. He told me that for the same price, he would send me the original factory image for that radio as well as update 1.01. So I paid 20 dollars for it, more than willingly for a chance at getting my AA wireless back. And it worked!! Loaded a new sd card with the internal firmware 1.0 and then did a firmware update to 1.01. Android auto wireless is back to working incredibly. Seconds after I start my truck my maps are on the screen! SO... if anybody is having that same weird issue and needs the original nex4400 firmware 1.0 file, I have it! Just let me know and I'll figure out how to post it so you can download it for free. I'm just so happy right now!
