What is the SD Card password?

 

A: LKPFeD4BcVzESR2Y

Thats the old password. It doesn't work anymore.

**correction, that password doesn't work on some models anymore

I now have two SD cards that Windows won't see in the reader.  By what method and means would I apply this password if my computer won't even recognize that the card is in the reader?  Will the card reader see the card under Unix?  Is there a Unix environment that runs on windows so I can access the card if indeed Unix will?  Is the password applied through the testmode program?  If so is there a quick start on using testmode?  I just want my cards back.  Knowledge is a fine thing to have, it has far greater value when it is shared.

There is no way to do this on windows or any sort of VM.

You need Linux with a patched kernel that allows you to execute a special command called CMD42 that locks and unlocks and can erase SD cards.

You also need the right hardware. You have to have a built-in SD card reader that connects to your motherboard via a PCI bridge, not USB bridge. Thats why a USB adapter won't work.

I bought one of the ebay oem copies to replace the failed SD in my W4500nex. Lasted about 4-5 months and now it's doing the same. I'm about ready to give up on W4500 it's so unreliable.

Of the newer Pioneer units, do we know which ones don't have firmware on SD cards or don't have this issue with bootlooping?

Requirements are wireless apple carplay. Nice to have would be Android Auto (wireless). Nav not required as I usually use WAZE for the police alerts.

Any insight would be appreciated.

The ebay copy of oem SD of course was just some no-name sd card, go figure.

Thanks.

I bought one a bit ago that came on a SanDisk card and it's been solid.

I put an image 1.0 on SD card for 4400NEX , but i needed the 1.02 .

Can the SD card be formatted or re-flashed ? is the SD card useless at this point and i need a new SD card ?

Any external tools/software to force formatting the SD card ?

 

Thanks for the help in advance

Yes.

So if you flashed but didn't yet put it into the radio, the diskpart commands and videos linked would work.

If you already put it into the radio, IR has been locked by CMD42.

To unlock it, you need to have a Linux kernel patched to run CMD42 (https://media-www.micron.com/-/media/client/global/documents/products/technical-note/sd-cards/tnsd01_enable_sd_lock_unlock_in_linux.pdf?rev=03f03a6bc0f8435fafa93a8fc8e88988)

Not a trivial task to get this working.

I got 1.04 from them. 

Mine says 1.06. But I purchased from a different seller than the link @DD36 posted.

I'll see if I can get the checksums to compare.

Also, isn’t the underlying problem that the 16GB card fills up with logs or something? So wouldn’t a 32GB last longer?

That was one thought but I don't think that's the case. 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.

Also posted this on the backups thread.

Looks like there are some eBay sellers selling OEM SD cards for w4500nex. Cheaper than pacparts...if links aren't allowed, please delete. But can eBay search "OEM AVH-w4500NEX"

Does this bring back android auto? 

yes, but you have to factory reset your radio and delete the bluetooth lairing from your phone

Ignor duplicate post.

link to the 4500 image. made it using the info from this thread 

4500 image here made using the info from the software error 4500 thread.

Link to Image

Edited the sysd.conf file as specified by @jrgutier and no touchscreen for me either.
I'll try to only include the 4500 product info as others have tried and hopefully that works...

Edit: turns out I was sold the wrong unit....box said 4500nex but label said 4400nex.

I now have a 4500nex and the instructions works great.

Also, got myself a Nokia c6-01 and can now finally erase the SD cards that get locked during trial and error.

If anyone needs cards unlocked, feel free to send them my way and im happy to unlock and mail them back. Send a pm.

Or find a Nokia e series or n series or c series on ebay and those should work to format it.
