Did you also delete the copy that [MENTION=2579282]gpmg762[/MENTION] mentioned in Post #630?

This sort of confuses me. If there is no contact app in Android then what did [MENTION=5642747]nikko82[/MENTION] change in Post #1186 and pointed out those files in Post #1216?

Have you tried using ExDialer - Dialer & Contacts. It supposed to be an alternative contact and dialer app for the stock version that come with smartphones. The problem with trying to port the contacts/people app from other devices is that it usually uses a Shared User ID that is tied to the manufacturer's key signature. And trying to resign all the apps that might use that Share User ID a big pain.

I have a question for those of you that have problems with the newest firmware version and ended up with a dysfunctional GPS. Did you guys bother going into the model section and selecting one? I remember reading from Amobile page that is one of the necessary steps after upgrading your system firmware. If the GPS is a part of the MCU then it would stand to reason that it may also need an update realign the difference between the new Android software and the MCU firmware.
[Android Head-Units] atijasa:
don't get me wrong... but I did the factory reset today, unleast 6 times... and finally everything is working.... (not mentioning my angry wife, because I'm spending my last three days in the car fixing this Chinese crap of gps).... sooo.... yeeah ... i'm not able to help you.... sorry ....
[Android Head-Units] KID52:
No worries, appreciate your efforts.

It just means at the moment we are unable to confirm the cause or solution without replicating the circumstances. At the moment it is implied that the 2.6.68 complete updates breaks the GPS. Then your proposed fix is to factory reset, then install the 4 file version of 2.6.68.

I have a couple other questions.

Has anyone tried the 2.6.68 minimal update going from 2.6.62? Does it break the GPS?

Do any of the other complete updates break the GPS? (providing that 2.6.68 has NOT been installed prior to this)

Hopefully someone else will be able to perform the test. I would have no problem trying it if I had a spare antenna, but it's fixed in the car. So I have no way of telling if the GPS is working or not. Plus it's too cold to take the stereo outside and connect it back into the car to do the tests :p

So, in summary the following needs to be tested if possible.

2.6.68 complete installed - breaks GPS

Factory reset

2.6.68 4 file version installed - should fix GPS

Factory reset

2.6.68 complete installed - should break GPS again

Factory reset

2.6.68 4 file version installed - GPS should be fixed again

I guess for completeness it may be worth trying without the factory resets if the above works.
[Android Head-Units] donaldta:
You might have forgot or missed the part about rebooting after the firmware update, selecting a model and rebooting again. Just in case, the changes in the Android side of things breaks the communication of certain components on the MCU side of things.
[Android Head-Units] KID52:
That is worth testing separately, but I do not think that the method [MENTION=5507055]atijasa[/MENTION] mentioned to fix the GPS issue included changing the model.
[Android Head-Units] Black6spdZ:
I can confirm this works without problem.. my system came with .62, I did a minimal upgrade to .68, minimal back to .62 and minimal to .68 again with no problems to GPS functionality.
[Android Head-Units] Dan_Austin:
Almost perfect...

Cool find. I don't really care about th 7" vs. 6.2" or even the CPU. I do like the knob and button layout, and am slightly bummed that

more specs are not listed. My target vehicle is an old Datsun, and I'd need to hack the dash to make space for a double din. If that

7" unit is shallow like the Parrot AS it would be a no-brainer for my install...
[Android Head-Units] fcortes626:
i test drove my car using the files i asked for and it had a better lock but i did lose signal twice. I am willing to try to do a factory reset but only if that doesnt remove my sygic and maps that i downloaded from the internet because the ones that came with the unit some how got deleted. I can tell you that in the process to restore the original sygic app and maps i did a factory reset and downgraded to 2.6.23 complete and back to .68 complete and once i got sygic and the maps installed noticed gps wasnt working. i never did try .68 minimal. and i never did select a model after upgrading. i dont know what that is for so i never touched it. if i am supposed to select one which one do i select? also if anyone knows how i can keep sygic and maps after doing a factory reset i am willing to try it out.

also anyone know where or if there is a tf card for the maps on this unit? i emailed my seller and he said it was located on the card slod in the back of the unit. took out my unit and didnt see anything. I dont think this guy knows what he is talking about and i think the tf card is just a partition in the system.
[Android Head-Units] sciallo:
Those posts are about the built in bluetooth/phone app. That like the rest is more MCU centric than it is android. The contact list in there is contacts imported from the phone through bluetooth. It doesn't provide the android contacts function that tablet talk requires and quite frankly it's a piece of junk. Doesn't seem to import all contacts with most phones, it only stores a limited amount of information and doesn't sort right. I'd like to be more specific, but I can't even open the software without a working MCU :(

Crappines of the built in phone software is in my mind 75% reason to install tablet talk to run along side of it, the other 25% is text messaging...

I don't have tablet talk installed anymore and a system it's not really worth rooting and installing anything on until I figure out my situation (it doesn't even stay on for too long, it shuts off by itself) so I can't tell you exactly what message tablet talk was giving, but something along the lines of needing contacts, I don't know if the app you mentioned or one of the many like it would provide that as a framework for other apps, can't try but I would like to know. Also, would it still sync with google contacts and the like?

It would be nice to be able to get the whole google framework working as it should. Contacts Calendar email and all...
[Android Head-Units] atijasa:
yes factory reset will uninstall sygic.. and all your apps ...just copy the sygic folder from Sdcard... to some directory to extsdcard.... after upgrade insall sygic and revers first step.. and thats it...

if you need maps for Europe (sygic)... here is the link

http://betopseller.com/img/imgs/pages/EU-RL.zip
[Android Head-Units] fcortes626:
ok so factory reset and instal .68 minimal? or factory reset, install .62 complete and then .68 minimal?

and do i need to select a model too?

thanks but i only have mexico maps and california for now. im trying to figure out where i can move the maps so i can download hte rest of hte us maps and not fill up my units disk space.
[Android Head-Units] atijasa:
try this... thats what I done.. downgrade to 2.6.23 complete... factory reset.... upgrade with 4 file version (link that i provided earlier)... and thats it... it worked for me :) ... you will be on 2.6.68 and hopefully your gps will work correctly...
[Android Head-Units] fcortes626:
ok so i just downgraded to .23 complete and did a factory reset. i have 8 fix of 13 sats. dont know if that is good or not. i havent tried updating anything yet decded to first check how the gps was working. i will update this post once i have upgraded. i will first try updating to .62 complete since gps was still working on that version and then try .68 minimal. if gps breaks then i will do everything all over and try the other 4 file upgrade. last thing i will do is select the model. the bad thins is that the files download slow. about an hour for both,
[Android Head-Units] donaldta:
I'm pretty sure he's trying to help KID52 figure out why the process broke the GPS. Instead of blindly trying stuff, like you did. This will help others avoid duplicating the problem and correctly address the issue. I doubt the problem is with the firmware but more along the line to follow the appropriate directions to install it. Although, I guess since we're blindly sharing the updates, the appropriate instructions are not included. My hunch is failing to select a model after a complete install to .68 is what did it, since the MCU is not on the same level as Android.

---------- Post added at 06:40 PM ---------- Previous post was at 06:30 PM ----------

Can you please check if the values of the model change in between updates? I know you're doing a minimal install so my guess is that the values will not change. Whereas, if you did a complete version update, I'm pretty sure the values will change. Making the model selection necessary as instructed on the Amobile page.
[Android Head-Units] fcortes626:
sure. first i will do a complete version update to .62 then a minimal update to .68

on .23 it says 3.3.8 it only showed one so i chose that one and now it says mcu says unknown. when the unit starts it says disc has stopped., the home button wont work, i try to do a factory reset and settings force closes, and when i turn off the car you hear a loud thump on the speakers.

cant even update because settings force closes. i think i am screwed and might neet to get an exchange
[Android Head-Units] donaldta:
Hmm... did you reboot the unit after the system update but before applying the model change? In retrospect, I should have waned you to not perform a model change when "back-dating" the firmware. As, I believe that is what caused [MENTION=3081576]sciallo[/MENTION] to brick his MCU. I do not think the MCU likes going backwards. I'm sorry about that.

How about if you power off the unit (both yellow and red) disconnect for a little bit then connect them again to for a cold boot.
[Android Head-Units] fcortes626:
that didnt work. im going to email my seller to see if he could exchange it.

i emailed the seller and told him that the i was having problems with my unit force closing apps and the home button not working and if i could exchange the item. lets hope he will exchange it. its been less than 30 days. If he wont exchange it i will use my squaretrade warranty.
[Android Head-Units] sciallo:
Oh crap....

Welcome to the club :(

It's official...

DO NOT PERFORM MODEL CHANGE OR MCU UPDATE WITH ANY VERSION LOWER THAN 2.6.40!!!
[MENTION=1915855]KID52[/MENTION] maybe post this warning on the OP...

The only other person that reported mcu unknown claimed he was an early adopter at the time testing things with the manufacturer, and this happened with an old firmware... they ended up sending him a new board (which is what I'm hoping to get at this point) you might be able to get that too and save on shipping the whole thing back...

I would love it if your seller could push the manufacturer for a fix before resorting on exchange... If it's an ebay purchase, open a resolution ticket and they would have time to resolve the situation while you're still covered, as long as the ticket was opened before the end of the initial return policy...

On the gps issue:
[MENTION=1915855]KID52[/MENTION] did you create the complete - partial versions of the firmwares? I think I sort of understand the thought process behind it, but it might just be that something is not right with that. Can you try to backtrack and list what files each version came with and wich you mixed in (if any) to make partial and complete?
[Android Head-Units] KID52:
I'm actually thinking of just removing the firmware that I did not get from Peter Chan, as those are the two that seem to be causing major issues - 2.6.23 with the model change issue, and 2.6.68 with the GPS issue (but only for some, so really need to be able to test what is causing it exactly, and what the solution is).

As mentioned above, I did create the complete/minimal files. I will post a complete list of all changes made compared to the original RAR files when I have a chance. I do have a copy of everything, so no need to worry there.

With the files being encrypted it is hard to know what is, and is not required for a "complete" system change.

For example, if the manufacturer sends update #1 containing 10 files, #2 containing 2 files, and #3 containing 5 files, what happens if you apply update #3, but want to revert back to #2? By only installing the 2 files included with that update, does it do a complete revert, or did the manufacturer not send the files which were later changed in #3 because between update #1 and #2 they were not altered, meaning that when you try to apply #2 after going to #3, you still have some changes remain that were made by #3. Or, perhaps there is a "main" file, and then other files which do smaller alterations, in which case the "main" file would do a complete install of any firmware, in which case, the additional smaller files that are included would have a large impact.

I hope that confusing mess of text makes sense...

I guess I can test this though, if I install 2.6.62 complete, then install 2.6.62 original, then install 2.6.62 complete, take a copy of the folders for each and see if there are any differences, if there are then it shows that having the exact original files for the update does make a difference.
[Android Head-Units] fcortes626:
i opened the case. lets see what they say.
[Android Head-Units] sciallo:
.62 - .62 - .62? not sure I follow...

I do think .23 is to blame, it was something like their alpha, it bricked units in some cases (or maybe it bricks newer units). If it wasn't for the fact that it seems to help fix the GPS problem (WITHOUT MCU UPDATE) I would say remove any links to it and warn against it. I know I won't be touching it again if I don't have to.

What files came as an update to .68?

If it was originally the partial, then partial alone might work fine and not break anything...

- I started trying to note what's what in the update files, unfortunately didn't really take notes...

We know one file (the biggest) is System...

- I immagine one is the MCU, the 64kb file, as that's the size of the STM8AF we have on our board and according to the documentation all unused bits in the firmware are filled with a default failsafe value.... Though it seems updating firmware doesnt update MCU (Please if anyone is updating firmware either upgrading or downgrading, confirm this, take a note of your MCU version before and after update and let me know if it changes without performing model change or MCU update, let me know from what version to what version you updated)!!!.

- I bet one of them has to be kernel image... Not sure which one

and some (or at least one) files are needed for the update process but don't appear in the list when updating....

Namely if I remember right fa6e4352-ec9e-11e2-9ffd-000c29ba27c0 I think that file might be "directing" the update and who knows how the process goes...

I think it would be beneficial to try to make heads or tails of how the process works, what files are used and needed and what's what... Still would be majestic if some genius could figure out the darn "encryption" on these files...

---------- Post added at 11:06 PM ---------- Previous post was at 10:59 PM ----------

Fingers crossed :fingers-crossed:

Do you live in the us? If so and there is no soft fix, maybe they can send you two boards for the price of 1... I'll pay for it :)
[Android Head-Units] donaldta:
Wait, wtf? Seriously? You made those "complete" versions? OMG. I had thought your manufacturer/reseller contact gave you those files. I hadn't realize you Frankensteined them. That is really, really dangerous considering the contents of those files are unknown.

I sort of understand what you're saying but I'm still slightly lost after re-reading it several times. I may be confused or stuck on the idea of attempting to turn what may possibly be many incremental updates into a differential or full update.

This is probably prudent especially if the relative update files changes part of the ROM which contains the MCU updates. Though, I think this should have probably been done before posting all the different versions.

I'm sorry but I'm a little bit dumbfounded. I may be looking this at the wrong perspective but this seems analogous to placing three bullets into a revolver then handing it over to a bunch of kids whom are about to play cowboys and indians. I mean, I know you meant well by trying to make it easier but it seems the good intentions were not well thought out.
[Android Head-Units] KID52:
Yes, basically my idea is following what was mentioned before regarding the partial 2.6.68 update apparently fixing the GPS. Let's see if I can explain...

For the partial 2.6.68 update to make any difference, or fix the GPS issue, the update process has got to make different changes than the complete version I made, as we know that the 4 files in the partial update are identical (bit for bit) to the ones in my complete version.

So, if I install 2.6.62 (I guess it could be any version, even 2.6.68) complete, take a comprehensive copy of all files on the unit (excluding external storage), then install 2.6.62 original update (provided by Peter Chan) which has less files than the complete update, take another comprehensive copy and compare, there must be some differences between the two, in which case, the specific files in the update do matter, and I cannot get away with releasing complete/minimal versions, it must be as the factory sent.
[Android Head-Units] fcortes626:
yes i live in the U.S. I didnt tell them i messed with the device so they should exchange it.:silly:
[Android Head-Units] KID52:
No, you are right, it is something that was meant to be easier, but without proper testing I should not have released the files.

The original files I have were sent to me by the manufacturer, except 2.6.23 and 2.6.68. These are uploading again now and the complete/minimal files will be removed.

I am still going to run the test I mentioned to see if there are any differences. I think my previous post explains it a bit better.

Just for reference, the factory appear to have done something similar to what I was doing with the complete/minimal. 2.6.40, 2.6.60, and 2.6.60-2 all have the same number of files, that being 7. 6 of which remain identical through all three updates, so just a single file is different in each one. Then with 2.6.62, only two files were included, both different to all previous versions with the same name. Then again with 2.6.68, which includes 4 files, all of which are different to previous versions with the same name. Two of these files have completely different names also - "8baf147e-ea4a-11e2-b181-000c29ba27c0", and "8ffd2eb4-ea4d-11e2-b23a-000c29ba27c0". But as everything is encrypted, you are right, no one knows what they are really doing, and it's like playing roulette - I apologize for my stupidity in this and just hope it hasn't caused any lasting damage. I didn't alter 2.6.23 though, so blame that on the factory!
[Android Head-Units] sciallo:
I'm pretty sure updating rom shouldn't be considered "messing" with it. The unit should be able to recover from a software update gone bad without its warranty being void... They will need to figure out a way evenctually. The bootloader still works, the update process still works, I'm amazed there isn't a MCU recovery process other than the now broken one initiated from within android...

But yeah, I hear you, better chance of getting it exchanged without an argument if they don't know....

When I exchanged the OUKU it was the same scenario, it got fixed in software (they released the right MCU) 2 days after I spent $65 to ship it back in exchange for this one, they knew a firmware update is what broke it and tried to get me to fix it before I sent it back, but they couldn't get the manufacturer to help for a while.

I'm out $465 after shipping the fist one back, and I now have a broken AN-21... Not feeling too happy. I wouldn't ship the whole thing back again for yet another $65 even if they did honor a warranty return on an already replaced and upgraded unit... I think if it came to that a replacement board would be a cheaper choice... they would probably let you keep the old one too, which migh become the ginny pig/spare in the future if a software fix does come about.
[Android Head-Units] KID52:
Agreed.

The unit is able to install system updates through a key combination on boot, so why not the MCU if altering that is more likely to break the thing.
[Android Head-Units] fcortes626:
lets just hope he pays for shipping costs since its considered a defective item? i have returned defective items where the seller payed for the shipping costs.
[Android Head-Units] KID52:
You have opened a case on eBay right?

If that is the case, and the seller refuses to pay for return shipping, just wait until you can raise it to eBay and then eBay will normally cover the return cost by giving you a pre-paid shipping label.
[Android Head-Units] fcortes626:
yes i did. i even told the seller i am willing to pay the price of the unit and he can refund it to me once he gets my defective unit back. because all i need is the unit dont want to have to remove all the wiring.
[Android Head-Units] bmj67:
2.6.23 was sent to me by roadmaster. It was actually a downgrade from the factory because something happened with sygic and I couldn't remove it even after factory reset. I have not upgraded software at all and not sure if I want to with some of the issues.

For the ppl that bricked the unit did you downgrade to 2.6.23 successfully and brick it after the mcu update or model change? Or did the brick happen after using the system update portion. If it only bricked with the mcu update then we should put a warning to not update the mcu or choose a model.

It downgraded fine, the model change is what killed it, yes, a warning would be the least...
[Android Head-Units] atijasa:
did you try to press reset button for 10 sec (tiny buton on front of unit)... having the upgrade files on ex. sd card... it should start boot upgrade automatically...
