Tried this for about a week now on my AVH-4000NEX. I can easily navigate to the Initialize Factory Reset, it gives the OK on all section except GPS, Turns Blue and says to turn off power to test Bluetooth. After I remove the USB and restart, same old password screen.

Hello. I have a similar problem. I also use the AVH-4000NEX. After I select the Factory Reset option, after a couple seconds mine turns red. Waiting several minutes and nothing else happens. Cycle the power off and on and the unit still asks for a password. Is this because I'm on the newest firmware, or am I doing something wrong with the reset procedure?

Can someone walk me through this step by step.  I really don't understand this computer stuff. I downloaded the file and extracted everything then put them on the zip drive and plugged it into usb1. Nothing happened. I don't want to be without my stereo for weeks sending it to Pioneer. Please help! 4200NEX

Did you turn on your Pioneer DVD AVH-XXXX unit only to be greeted by a "Enter Password" page, along with a "Password Hint" page?  That's exactly what happened to us after installing a unit that my best friend inherited from a deceased friend.  Unfortunately, she's passed and the hint that she gave wasn't good enough for my friend to guess.  Now what, I said!!!  Some hits seemed to suggest that one needs to bring the unit to Pioneer Service.  Even the manual suggests doing so.  First, I tried hitting the "reset button" located along the front face plate, towards the bottom right.  This didn't work.  This would have been too easy, and even the manual states that it doesn't clear everything.  Then I stumbled upon the concept of putting the unit into Factory Service Mode.  One can actually retrieve the password, by first putting the unit into factory service mode and then by reading an actual ASCII text password file.  After not being able to navigate to the specific directory that contains the password file, as I couldn't find a "usr" folder, I noticed and tried successfully by performing a factory reset instead.

 

 

 

 

First, go here and build a set of boot files required to put your unit into factory service mode:

 

 

 

 

 

https://jenkins.adamoutler.com/job/Customize%20BSP/build?delay=0sec

 

 

 

 

 

Keep everything defaulted except for the following two settings:

 

 

• launchMode=TestMode 
• testSubMode=Serv Mode.  

 

 

 

Your corresponding readme.txt file should look like the following:

 

 

 

 

 

Your SDCard Password is LKPFeD4BcVzESR2Y

 

 

The password was set to LKPFeD4BcVzESR2Y

 

 

set Boot Mode ullaunchmode to 0 (Default:Normal) at 4

 

 

set Launch Mode ullaunchmode to 1 (TestMode.apk) at 8

 

 

set Test SubMode to 1 (Serv Mode) at 12

 

 

set Boot Image Side Flag ulbootimageflag to 0 (Default:Side A) at 16

 

 

set Recovery Image Flag ulrecoveryimageflag to 0 (Default:Side A) at 20

 

 

set Debug Switch uldebugswitch to 0 (Default:Disabled) at 24

 

 

set USB OTG Switch ulusbotgswitch to 0 (Default:Host Mode) at 28

 

 

set Mem Check Flag ulmemchkflag to 0 (Default:no) at 32

 

 

set Sub Boot Mode sbspinfo.ulupdatesubflag to 0 (Default:Side A) at 36

 

 

set WARP!! sbspinfo.ulupdatesubflag to 2 (Default:Enable Warp) at 40

 

 

set Update Flag sbspinfo.ulupdateflag to 0 (Default:Recovery-Update) at 44

 

 

set Update Sub Flag to 0 (Default:SD Card) at 48

 

 

set UI Update  Flag to 0 (Default:non-updating) at 68

 

 

CRC32 applied to warp Disabled image.

 

 

CRC32 applied to warp Enabled image.

 

 

CRC32 applied.

 

 

 

 

 

Plug a thumb drive into your computer.  I removed all of the files that were already on it, but I'm not sure if this was completely necessary or not.  Save all of the files that you just generated onto  the thumb drive, by hitting on each file, one at a time.  The files that do not open with a "save' dialog window, do not need to be saved, ex. readme.txt, SD*.txt.

 

 

 

 

 

If you can't find the page above, or don't want to build your own set of files, here's a rar compressed set that I had generated and used successfully for my password inhibited unit.  I would imagine that these should work for most Pioneer AVH DVD units.  Please feel free to grab them from the following dropbox rar file, also attached to this forum.

 

 

 

 

 

https://www.dropbox.com/s/0xp6roa4xnq0zr2/PioneerAVH4000FactoryService.rar?dl=0

 

 

 

 

 

if you do grab my rar compressed file, please make sure that you extract the individual files before copying them over to your thumb drive.

 

 

 

 

 

The port that you need to plug the thumb drive into is "port 1".  On my unit, AVH-4000NEX, port 1 is the top rear port.  

 

 

 

 

 

Power up the unit.  You should first see the password page, then after a little more time, the Factory Service Menu.  Scroll down, select and execute "factory reset".

 

 

 

 

 

Voila, "Factory Fresh Unit"!!!

 

 

 

 

 

No more password, but actually, we ended up setting a new password along with a new password hint as well.  But keep in mind, this is a total factory reset, like the type that first prompts you for your language, etc.

 

 

 

 

 

I hope that this help you save the time and effort that I went through and/or throwing out $$$ to pay some greedy person on Ebay, most likely for exactly the same procedure that I've described in this post.

 

 

 

 

 

If this works for you, please respond to this topic, as I would love to know that I've helped others out with the same issue and have saved you both time and money.

PioneerAVH4000FactoryService.rar

 

when I do this rar file, the bytes do not match nd says zero for all except the sdunlock says 534 kb, I don't think this is right. 

Had to create an account just to thank you so much! Worked on a AVIC-5100NEX I purchased off of OfferUp! If I knew who you are I'd send you some cash!

I didn't have a USB stick so I put the files on a Micro SD card and it worked in the 5000NEX.

hi, am clicking on the dropbox address and its not loading, it says the site cant be reached and the server ip address could not be found.

please advice

i managed to get the file, now how do i make my 8gb flash a thumb drive?

Thanks alot guys the procedure worked very well for me

PioneerAVH4000FactoryService.rar

Hey Mark,

I downloaded the .rar file,  decompressed it and copied the files to a 8 GB USB stick.  I had previously wiped the stick and reformatted it.  I'm using a Mac.  I formatted the USB stick first time as MS-DOS, tried it, nada.  Went back and reformatted the stick as ex-FAT, put the files back on it, checked to make sure they copied over.  Deck still did not recognize the stick.  Now in my case, the deck (NEX 4201) was installed with a USB dongle out to the glove box from port 1.  I have used this connection before to update firmware, and it works fine.  However, in this case, the deck did not see the USB stick, or to be precise, the deck did not go into 'factory service mode.'   I've rooted other Android devices so the process is not completely foreign to me.  Any suggestions?

Excellent, the last link worked perfect. Thank you so much.

I tried the steps mentioned on this thread for an AVH4200NEX as well and no response from the unit. Still see the password entry window after waiting a long time.

Tried on an 8GB drive, 4 GB drive, both FAT32 formatted and both in the USB1 port. Any help would be appreciated!

yeah neither worked on my AVH4200 i think is something to do with firmware update

omg! works on my 8850! same issue, battery died and prompted for password on my 2nd hand pioneer set. Only thing is that I need to go back to the installer to get the steering wheel controls done..

Cravatts, just want to say thank you for the post. It worked perfectly.

AVH4200 over here too. Nothing workes for me either

Worked like a charm!!! My password screen was out of calibration and I couldn't enter the password. Factory Reset was the perfect solution! Thanks for sharing!!

Is this build server still working/maintained?

https://jenkins.adamoutler.com/job/Customize BSP/3727/console my build is failing.

Wow you're a life saver! I have 4200nex and it worked. I couldn't type in my password because is has a symbol in it and the sensor on the screen wouldn't let me go to it, when I pressed anywhere along the bottom it would only select whatever keys are above. With this usb I did a factory reset. I downloaded your rar file, extracted it and saved on a formatted usb drive. I had to do a full format, the quick method didn't work at first. I also used a 16gb usb drive. Thanks a lot!

It says that the domain has expired. Can someone PM me the files that can be generated from Jenkins?

I have an AVH-4400 NEX.  I just changed my battery in my truck and now my screen calibration is off and I can't enter my password.  I tried the above  solution but it did not work.  Has anyone had any success fixing this problem on this model?  Thanks in advance.  I cannot understand how Pioneer has not fixed this problem.  I know my password but cannot enter it due to a fault in their software.  I find it insane that I may have to pay them money and lose the use of my stereo for weeks because of poor software. 

You can send a video with your problem

This password fix did not work for my 5000NEX stereo (re branded as f860bt in Europe) with SW version 1.21. 

Thanks Cravatts!!! Grabbed your rar file, extract to a thumb drive (I used WinZip) and plug into the unit's USB. After about 15 seconds, I'm in Factory Service Mode! Worked like a charm. I'm from Seattle, WA and I have an AVIC -5200NEX.

Again, thanks for putting in the work (and time). Your good deed is saving a lot of us from being taken advantaged of by some eBay vultures.

Hi! 

It didn't work for me, I used a 2gb drive, copy the files one by one to de root directory, it didn't do anything :/ any ideas?
