In Topic: Password AVH Reset

10 September 2017 - 04:09 AM

Fantastic!!! I have been occasionally checking in and patiently waiting to see if someone would eventually find my article and use the information that I spent time writing up.  Where are you hailing from?  Canada, France, etc.?    A response like this give me the encouragement and desire to continue to give back to the community that I learn so much from.  Between Youtube and blogs like this, one can learn so much.  It wasn't that long ago that the only way I could learn how to do something was to go to a library and hope that they had a book, magazine, etc. that had the information that I was trying to find.

Please respond if this helped you out, as I would hate to see people throw their money away by having to pay someone on Ebay for this knowledge.

In Topic: Password AVH-X8650BT

17 July 2017 - 01:55 AM

I just got done resetting the password from an inherited unit from a person who is now deceased!!! :-(  I can't beleive that there are folks on ebay who charge up to $26 for this knowledge!!!  This worked for my unit, AVH-4000NEX, but according to the EBAY auctions,  should also work for many other models as well.

 

First, I tried hitting the "reset button" located along the front faceplate, 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 after doing a bit more research, I discovered that one can actually retireve the password, by first putting the unit into factory service mode and then reading an actual ASCII text password file.  After not being able to navigate to directory that contains the password file, I noticed and tried successfully by performing a factory reset.
First, go Here and build a set of boot files required to put your unit into factory service mode:
 
 
Keep everything defaulted except for the following two:
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.
 
Put an empty thumb drive into your computer.  Save all of the files over to 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 for my unit.  I would imagine that these should work for most AVH units.  Please feel free to grab them.
 
 
 
The port that you need to plug the thumb drive into is "port 1".  On my unit, AVH-4000NEX, it is the top rear port.  
 
Power up the unit.  You should first see the password page, then after a little more time, the service menu.  Scroll down, select and execute "factory reset".
 
Voila, "Factory Fresh Unit"!!!
 
No more password.  Factory reset to the point that you first need to select 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 thing.
 
Please post to this forum if this worked for you as well, as I would love to know that I helped other folks with this same exact issue.
