CatholicJedi Posted March 26, 2015 Report Share Posted March 26, 2015 I tried to find any evidence of people having BT problems with their new x100 units, but came up empty. I think BT works fine on the x100 units, so unfortunately I am not hopeful that the next x100 update would help us x000 owners I think there is hope to modify still (I can't, but I am sure someone can) - there is no upgrade in the bluetooth version, both have: Bluetooth 3.0+EDR certi- fied I checked the manual on both for the information.

epsilonkore Posted March 26, 2015 Report Share Posted March 26, 2015 while the versions may be the same, they may use a different bluetooth chip that would require a different driver... or of course, it could just be a firmware flash difference. Has anyone inspected to see if the BT chips are the same? Quote Link to post Share on other sites
newtonfb Posted March 26, 2015 Report Share Posted March 26, 2015 If its new chip, wouldn't flashing old BT firmware do the trick? The new Bluetooth folder I think is about 2mb bigger. Quote Link to post Share on other sites

newtonfb Posted March 26, 2015 Report Share Posted March 26, 2015 how would you flash the BT firmware? and is that reversible? sorry, I am not a programer. databases are my things lol With each firmware there is a folder called "bluetooth" the one for the new 4100 is about 2mb bigger than the bluetooth folder for the 4000nex. For some reason when you flash the new 4100 firmware the option in "A/V output" for "Bluetooth Audio" is stuck to off. Even if you flash the new firmware with the old bluetooth folder it gets the same result. That seems to be the problem. The stereo still reads the song titles or whatever your trying to play but the Audio does not work. Quote Link to post Share on other sites

RRSpikes Posted March 26, 2015 Report Share Posted March 26, 2015 Im confused on what you're asking? We have the files for both versions. The x100's 1.03 firmware is only 1 part of what's needed. We need the BT firmware from the x100nex so the radio and BT communicate. This is of course, assuming that the x000nex will accept it.

X100 BT firmware: x000 BT firmware: what he is saying is that the nex x100 1.03 firmware files do not upgrade the bluetooth because the stock bluetooth on the headunits is already 31.41.30. So when we update our headunits we have the wrong bluetooth firmware and the unit stops working correctly. Quote Link to post Share on other sites
newtonfb Posted March 26, 2015 Report Share Posted March 26, 2015 Hmm interesting. So whats the bluetooth folder thats included in the firmware? Quote Link to post Share on other sites
epsilonkore Posted March 26, 2015 Report Share Posted March 26, 2015 So the bluetooth folder on the x000 series has PJ140BTHSAF.PRG while the X100 series has PJ150BTHSAF.PRG , one number difference. Has anyone tried renaming the 150 series to 140, and flashing the bluetooth on the older x000 series OS first, then if it takes, upgrade to the x100 OS? The sizes of each corresponding file in the bluetooth folder is very close, the BTL file is the SAME size, so is the UDP file. The SAF is the only one with a difference in size, and its .2 megs.

nezfotnemom Posted March 26, 2015 Report Share Posted March 26, 2015 This is so awesome. Cant wait for this to work! Quote Link to post Share on other sites
epsilonkore Posted March 26, 2015 Report Share Posted March 26, 2015 I have tried several combinations of the bluetooth files now to no avail :/ Quote Link to post Share on other sites
DP3343 Posted March 26, 2015 Report Share Posted March 26, 2015 I have an idea, but it's insanity. The NEX has a recovery system for if the radio has a catastrophic failure during the update like if lets say you turned off the car during. My guess is that it would be a full wipe of the system to return to stock, vs an update only changes the files that need changing. If I were to do this hacked update and then force restart the radio while it's going it might force it to do a full fresh install which could install the missing parts of the firmware that is causing it to act up. I'm not crazy enough to do this, but I'm tempted. Quote Link to post Share on other sites
