Once the sd card is placed in a unit and turned on the card becomes password protected. There are people here who say they know that password but I do not. Even if I did, I do not know how to unlock the card. Maybe others can help.
Is there some test-mode that we can boot into for the W4500NEX? I tried using what i found on the forum, even on my older 4201NEX, and I was unsuccessful.
If I can boot in a test-mode and can make a backup image, it would probably be ideal
There is nothing that I know of that can be done once the sd card is locked. Someone else can chime in if they have an answer.
So I recently had this problem. Happy to have found this thread. Even though I still encountered some hurtles. So have a ZF9350BT. Basically the SE Asian equivalent. On this unit the face is on a set of rails that slide out from the bottom which made this a challenge to get to the hidden SD card. The power went while I was working this at my kitchen table and I accidentally damaged the ribbon connection to the screen. Luckily I was able to have my local computer guy fix it for $60.
But had a seemingly good idea. He asked if I intended to sell the head unit. I said no, I’ll use it till it bricks. He said well if you don’t mind just cut out an opening for next time. And that’s what we did.
I’m trying to attach a few pictures but essentially he cut out a perfectly size opening to access the internal SD drive.

My 4500 failed and i real-programmed the same SD card (took countless hours to figure out how to even make the card visible in a computer). And then it still had bootloop issues after reprogramming. So I think the flash memory just starts to fail.
The other issue, even if it was a storage space issue is that simply putting it into a larger SD card doesn't mean there's more "usable" space available. The partitions from the image (specificially the partition where logs are stored) would need to be enlarged as well.
How did make the SD card visible in a computer?
I pulled the card from a working avh-4200NEX, but it's not visible in the computer and so I cannot backup the file image.

You need to find the password to unlock it, then get linux with a patched kernel that can initialize locked SD cards. Then unlock it with said password.
My 4400 died yesterday with the software error. I followed the steps but my head unit just boot looped with a static rainbow flickering screen and repeating. Is this a symptom of an incompatible sd card? It was a 32 SDHC 10 HP-branded card I had laying around.
I tried another Samsung 32 SDHC card and it did the same thing. The first one I used the win32diskimager and the second I used dd in Linux.
I'll have to order a 16 GB card to try that as a last resort.
Update: A 16 GB card was able to boot but then I ran into the 1.02 firmware issue with Android Auto :-/
Anybody have the stock file for the 4500NEX. Mine died. Looking for version 1.06 preferably. I know there is a 4400 version that is modified to work in 4500, but looking for the offical 4500 image if anyone can share.
I purchased a cloned AVH-W4500NEX SD card from eBay and would like to make a backup of the clone..
For whatever reason the SD card I received shows 2.2TB when inserted. I attempted using Ubuntu and ran the dd command in terminal, but it fails without even attempting. I can’t access any data on the card! Any suggestions?
Worst case scenario, I may have to purchase an official pioneer SD card to get a copy of the official w4500 firmware.. I’m just worried I’ll run into the same issue creating an image. (dd failing or SD card showing incorrect size)
Hopefully someone can write a step by step of making a backup of a EBay clone or official SD card. I can’t seem to find any information or guides that are specific to creating an image of a pioneer SD card.
I am no computer guru just an old man trying to keep my stereo working. My “guess” is that the card you got has already been in a unit and now it is locked by the stereo unit. It sounds like you have nothing to lose by putting it in your unit to see if it works. So far you have done better than I did, I ordered a card off eBay and never got it, even though it said it was delivered, maybe it was just not to me at least you got something I got nothing for my money but screwed.
When I got my card from PacParts it copied just fine, no issues at all. Expensive but I got my unit running again. I thought that I had posted somewhere on here the steps I used to copy, and it was using the dd command.
I can understand your frustration with that situation! It can happen to anyone ordering online. I am sorry you had to go through that..
If it helps, I know you have helped others like me who are having issues with the radio and are trying to repair it avoid ordering replacement cards overseas. I did made sure to check where it was shipping from.. Silver linings are always bittersweet.
Thanks for your input! I kind of figured that was the case.. either my card reader couldn’t read it or it was locked somehow. I figure that would be in the best interest for the seller..
As an update I used a Dremel to cut out a hole and tried the card like you suggested. It fixed the boot-loop/glitched startup failure, worked flawlessly and appreciably faster than the original when the original was working! So I’m not dissatisfied.. Wireless android auto and Apple CarPlay connect within 2 seconds of the unit clearing the warning screen! Steering wheel controls work as well.. so I assume I got an updated version of the firmware! It’s a w4500 I am loaning a family member so I was unable to properly test it. I’ll look into it further when I can setup a time.
What I can say with attempting/failing a backup and the card still working says a lot about the seller’s original firmware/attention to detail.
Is it ok to post the name of the seller from eBay? If not I can post a link of the item or dm the name. They have a few options just FYI.. cheap SD cards (non name brand), 2 pack of said cards, name brand cards, refurbished cards, name brand card w/ 18mo warranty.
As for next steps, I did some research and found the original replacement SD card from PacParts has been superseded. (Original replacement SD Card part# QXX3352 , Superceded by part# CXY8316 for the AVH-W4500NEX.
I found another seller on eBay selling the revision CXY8316 (unopened original replacement SD cards) from PacParts for a little over $50 after local tax! I ordered it yesterday after seeing how nice the replacement made the other unit work.
Currently I have a w4500 installed in my car that is sluggish and doesn’t automatically connect to wireless android auto or CarPlay.. that’s why I’m so adamant about backing up the firmware image. I’ll post an update once I receive it and attempt a backup.

Good idea, bro. I wish you have Image File of 9350 and like to share with me to save my 9250, appreciate to that. matt.wen@outlook
Has anybody successfully unlocked an SD card that has been locked by the 4500NEX? If so, mind sharing how you did it?

Did you happen to get the revision SD Card and try to rip the image?
