I have the same problem, i tried the KitKat ROM (it was working before, i just dont know which version, but the serial number was ok) and also the Lolipop ROM.

Several different programs could not fix my serial number, it stays the same. Either i am not able to use xposed correctly or my unit doesnt like these programs. (MTCB-KLD-v2.81)

I installed xposed, updated xposed, then installed the ID changer, enabled the ID changer, reboot, changed the serial number, reboot and nothing working. I made sure to press the "apply" button and it sayd that i need a reboot.

Neither the pro, nor the free version and also not an ID changer which somebody else linked here is working.

Is it possible that i lost root somehow? when i start a terminal and i change to root it works, but xposed never asked for root access.
[MTCB Android Head Units General] tux75at:
I tried to revert back to an older version, but now the serial number is just zeroes.

Is there a way to get back to Kitkat with a correct serial number? i had on the last version of kitkat a too long serial number and also on lilipop without beeing able to fix it with a serial number changing program.

edit: i did two times an install of the older rom with wiping all data
[MTCB Android Head Units General] 24stdpcnotdienst:
Same problem here checked root permission... After every reboot I get the same long serial number.........
[MTCB Android Head Units General] the-unknown:
try xprivacy and give a fake serial to tomtom. that worked for me
[MTCB Android Head Units General] ramco55:
So hello i have got the same problem...have you got an instruction for us with the xprivacy how we make this ??
[MTCB Android Head Units General] d3lboy01:
ive been out with my car stereo for a long time and still i have no luck with the latest rom

update_5_1_1_FUSE_800X480_RK3188_03_MAL_27_07_2016_Xposed_MTCB

tried the Phone Id Changer Pro and it just won't keep the numbers changed when i reboot

hope there's a fix soon as sygic i dont like and cant find how to turn up the voices :/
[MTCB Android Head Units General] TvBIFI:
For me Device ID Changer Pro worked on my rooted Joying MTCD no Xposed was needed.

https://play.google.com/store/apps/details?id=com.VTechno.androididchangerPro&hl=de

just entered 12 digits of any serial, saved and Tomtom could connect to Server.

The Sysinfo page shows a large number but Tomtom worked since change.
[MTCB Android Head Units General] tux75at:
I will try the method from DSA, maybe the big difference between working and non working ID Changer is, that some have a MTCD, i have a MTCB and Device Changer does not work .....

But then i thought these ROMs are only for MTCB
[MTCB Android Head Units General] d3lboy01:
still cant get tomtom to connect to internet

installed the lastest mtc but nothing :(
[MTCB Android Head Units General] d3lboy01:
thanks for the reply

i done that only thing that didn't work was the reboot

the stereo would just stay on like it crashed and a black screen i selected reboot from xposed

i had to poke the rst button to get the stereo working again :/
[MTCB Android Head Units General] d3lboy01:
the res is 800x480 and i have your firmware i believe with exposed on it

i did look to see if MTCB working on the MTCC before installing ;)
[MTCB Android Head Units General] d3lboy01:

[MTCB Android Head Units General] 24stdpcnotdienst:
MTCB Software is full compatible to MTCC devices!

Xposed on MTCD?

Hi,

i buyed a new MTCD unit and flashed the latest Malaysk Rom.

Now Tomtom wont working, probably because of the long Device id.

How did you guys install Xposed on your units? Can somebody give me a workaround?

Thank you very much.
[MTCB Android Head Units General] NoPublic:
I want to say is yea it worked for me now but not in the first time

I change the ID and reboot and then i started the app and the App sad no connection, so i was curios and retry the connection till it works , i think after 7 times it conntected and worked for me.
[MTCB Android Head Units General] 678hug:
Still struggling. Any help appreciated.

I'm on a RK3188 Android 4.4.4 running the latest Malaysk image.

Changed the serial no with the pro version. It shows as changed in the id changer software, but not in the head unit settings.

After a lot of reading, i've tried to install mtcservice-2.28 but it comes up with MTC-Service 'App not installed' message.

One thing i have noticed though when i swipe the menu screen down is that is says RK3066 Headunit service v2.15.

Is that right considering i have a RK3188

I've definitely got Xposed installed as it was loaded on when i updated to the Malaysk image.

Thanks
[MTCB Android Head Units General] inter981:
Hi @ll

i'm trying to install Tomtom on my specific 2 din chineese radio (RK3188, Android 5.1.1). I purchased Tomtom 'till 2019 and it's a waste of money if i can't make it work (19.95 eur x 3yr.). All was working fine 'till i've updated the software and MCU to my dvd-radio.

This is my new MCU and Android version info:

[B]MCU version[/B]
MTCD_KD_V1.82_1
Aug 26 2016 09:28:58

[B]Android version[/B]
5.1.1

[B]Kernel version[/B]
3.0.101+
root@chun-book #92
Tue Aug 23 20:06:29 CST 2016

[B]Build number[/B]
rk3188-userdebug 25082016.09:47:50

Steps:

- I've downloaded Phone Id Changer Pro 1.5.2

- Installed

- In the touchscreen i go to Settings -> Factory settings -> and i write *#hct#root# and i get somthing like "adb root on"

- I use the Phone Id Changer to get a new random serial (12 chars). It says i must reboot, i Do that, but nothing happens... It's still the old serial.

What am i doing wrong?

I think i'ts something about Xposed framework, but i don't know how to get and apply.

Can anybody explain it in a step-by-step guide?

Thankyou in advance,
[MTCB Android Head Units General] lordxenu:
You MUST have the Xposed framework installed and the SDK for your version installed and working before you can use the serial number changer.

The device MUST also be rooted (needs to be rooted anyway to install Xposed)

You install Xposed by downloading the zip frameworks and installing via recovery mode (e.g. clockworkmod)

If you don't have a recovery mode that can install .zip files then you could try using the FlashFire app to install it.

Then you install the actual Xposed APK

Then you install the module / apk for serial number changer ( Device ID changer didn't work for me, and there's a free one inside Xposed anyway called Serial Number Changer)

Then you open the serial number changing app and put in a new serial number

Then you go into Xposed framework > Modules

Find the serial number changing module and click it's checkbox so that it becomes active.

Reboot.

That SHOULD be it.

For me, I get a boot loop at this point so for me it won't work using Malaysk MTCD 5.1.1. image.

I would appreciate any help if anyone knows how to fix that. I have to do factory reset and wipe the data partitions to stop the boot loop.

For me, I cannot change the serial and get TomTom to work using Malaysk rom. :(
[MTCB Android Head Units General] Skater4599:
I'm having a strange issue with Tom Tom Go on 1 of my units, I bought 2 of the same units off amazon from pumpkinauto and both are KGL6. Installed latest Malaysk Rom and the xposed mtc-service 2.28.apk for tom tom serial number change, it works on the first one, but the second one the play store won't even let me download the tom tom app, it says its incompatible with my device?? I tried different version of the service.apk and no difference, and when I used xposed device spoofer it ended in a boot loop.

Any tips/suggestions to try to make tom tom show compatible? I spoofed as a samsung nexus S in xposed. I'm going to have to factory reset to get it to boot back up at all I think now.
[MTCB Android Head Units General] B3rt:
is there a solution for this?

I installed latest malaysk 5 (lollipop) rom, have xposed activated, downloaded the device id changer pro and activated in xpose.

But the ID does not change, it changes in the app but does not save, after reboot the original ID is still the same.

Resulting TT complains it cannot connect to the internet etc...

ON the old rom (4.4.4) i did the same and worked like a charm, but on android 5 it seems xpose id changer (pro and free version) simpley does not work anymore.

Does someone has a solution to change the serial to a lenght of 12 so i can start tomtom?
[MTCB Android Head Units General] colostro:
Download this file: https://www.dropbox.com/s/8p1o9v96vt287tk/mtcservice-2.28.apk?dl=0

Then activate the module on xposed and reboot.

Spoof with this and TomTom will work fine

Inviato dal mio Redmi Note 3 utilizzando Tapatalk
[MTCB Android Head Units General] B3rt:
Thx, tried it but does not work..

The first time after installing and spoofing (and reboot) TT crashes on start up.

I removed TT and reinstalled it and now it is giving the same error as before, cannot connect to internet bla bla

The service is running and activated in xposed,rebooted several times and ofcourse i activated the option to sfoof the ID.

I thing i am gonna go back to android 4.4.4
[MTCB Android Head Units General] ekanson:
"X Privacy Installer" may be the solution for you. Try it.
[MTCB Android Head Units General] Dek_92:
Hi everybody, I hope somebody can help me. I installed the xposed Installer in my Isudaar AA01, but i cant install the modules since it says that it have not root permission. I cant find anywere how to get root permissions, can anybody help me please?
[MTCB Android Head Units General] airlink75:
I confirm it works really good on my Eonon GA6163F with last Malaysk ROM.

Thank you so much. ;)
[MTCB Android Head Units General] B3rt:
I reverted back to 4.4.4 and here it works fine again.

But i noticed an other TomTom problem, TT is no longer suitable for my device...

When i search in de store and i want to install it i get a message that it is not compatible with my (rk3388) device..

My other android devices have no problem.

Is is new to me, suddenly the device is not supported anymore, i had to side load it to get it installed.

It was also not supported anymore on lollipop btw.

Ofcourse i contacted TT, they asked me some details and then i heard NOTHING anymore, not even a responce why i cannot download it..
[MTCB Android Head Units General] airlink75:
Maybe it is a strategy of Tomtom to not promote their product for head units, because they want to sale their own GPS.

But it is not forbidden for us to install Tomtom GO via apk. If you want to follow updates, you can download this app to check updates on Play Store :

https://f-droid.org/repository/browse/?fdid=fr.kwiatkowski.ApkTrack

I use it on my phone, because I don't use Google apps, but I think it can work good on our head units. I will test soon to see.

thanks for this colostro, with this mtcservice i was able the first time to start tt go on 5.1.1 malaysk rom on rk3188 (erisin es4046)

Thanks for this info. Is there a way to manually change ro.serialno?

I have a 5.1.1 Joying Intel Sofia unit with non-MTC* MCU. It seems Xposed is impossible to install on this unit, but there is root. With only root but not Xposed is it possible to change/shorten ro.serialno to get Tomtom working?

There is also a property just called serialno. setprop will correctly set its value, but tomtom shows no change in "app cannot connect to internet". set serialno ok, uninstalled and reinstalled tomtom, no change.

root@sofia3gr_car:/ # getprop serialno 110100303136473332008d9fca8e4300
root@sofia3gr_car:/ # setprop serialno 123456789012
root@sofia3gr_car:/ # getprop serialno 123456789012

Added to /system/build.prop the line "ro.serialno=123456789012" and rebooted but that doesn't have any effect.

This Joying Intel unit has no custom ROMs and no Xposed. It seems they set the serial in the ROM to 0123456789012345678901234567890. How can it be changed?

Thx to you all, my tomtom is working again after the id change.

[MTCB Android Head Units General] Skater4599:
Any Luck on this? I just got this unit myself and am trying to figure out the solution, Would really love to have TomTom Go working again!
[MTCB Android Head Units General] BrokenSpring:
Hello All.

So just thought i would post up my findings. It seems you need to have the device serial set to a 12 digit number and you need the device to apper to be a compatible phone and not a rk3188 unit.

As above i used device faker and device id changer.

On android 5.1 device faker would work fine but device id changer would not stick, the serial would revert to the normal massive one on reboot.

On android 4.4 both work and let me install and use tomtom.

You need to activate both modules, then use device faker to choose a compatible phone in the list (android 5.1 or 4.4) , reboot, then change serial to 12 digits, reboot. then go find tomtom install and enjoy.
[MTCB Android Head Units General] paccefierr:
very very good
[MTCB Android Head Units General] dude-nl:
Doesn't work for me, after changing Serial and rebooting the serial jumps back to original...
[MTCB Android Head Units General] BrokenSpring:
That was happening to me on Malaysk 5.1 rom.

I have also just installed booroondook's 5.1 rom and it does the same thing to me.

Does anyone know how to change the serial successfully on 5.1 rom's?
[MTCB Android Head Units General] dude-nl:
No one with a solution?
[MTCB Android Head Units General] Ejpi16:
The question is, is that the only thing Tom Tom needs? What does the xposed module change? Perhaps there are more properties set with the xposed module.
[MTCB Android Head Units General] dudarus1:
So today i managed to solve the problem. what i did was download device faker plus which allowed me to download tomtom in the first place. once it had downloaded i didnt start it. i installed xprivacy and enabled xprivacy in xposed. then open xprivacy and open settings scroll down to serial number and click randomise this should create a 12 digit serial. make sure the randomise on access box isnt checked. come out of settings and select tomtom select identification then this will give tomtom your 12 digit serial everytime it opens. at this point open tomtom and it will work. i had to uncheck some notification boxes in xprivacy as it kepted popping up everytime i installed a new app.

hope this helps someone
[MTCB Android Head Units General] Highwaymaniac:
Thanks for this guide. I've recently installed the Malaysk ROM and could not get Tomtom working. Followed this guide - working now!

Only have one real problem with TomTom left now: when engaging the rear view camera (by putting the car in reverse gear) TomTom seems to crash and restarts itself. This restart takes over the screen, resulting in a TomTom startup screen and no reverse camera screen. Have to take the car out of reverse gear en put it in again before I can see the rear view camera again. If anybody has a solution for this, please share.
[MTCB Android Head Units General] asianmulder:
managed now to download with device faker plus, followed other steps but app keeps crashing. any pointers?
[MTCB Android Head Units General] jonsfield:
Thanks for the detailed solution. I managed to get TomTom go running as per your steps. TT Much better on 5.1.1 with 2gb ram, it doesn't restart itself after I switch to another app like 4.4.4 kept doing. However, I found that live traffic feature would be connected one day and then not the next day and my wifi was working fine throughout since gmaps worked . Last week it stopped working completely and I've not been able to reconnect. Could it be xprivacy preventing connection or something to do with the serial number "spoofing"? I've contacted TomTom support with their only advice to reinstall their app. The TT web forums show similar problems on various devices but no real solution except for those who were using proxy servers - disabling the proxy worked for some. I'm on the latest TT version from the play store. My wife's TT on 4.4.4 connects to traffic via 3G with no issues.

Kind regards, Jonathan
[MTCB Android Head Units General] titof3b:
For those who can not change the serial number

There is another solution ??

The serial number changes at the restart

But still no tomotom that works :(

It takes how many characters to finish ??

8, 10, 12? 14? 16?

Only numbers or letters too ??

If yes, in lowercase or uppercase ??

Me **** this Chinese radio, I regret much :(

* I had to buy to put tomtom ...

Igo is not terrible for me :(
[MTCB Android Head Units General] Wout2426:
I tried every thing, no luck with TT. I have send a mail to TT, they have no solution, and they don't give support for head units.

I bought sygic, it has a 75% discount, lifetime maps and traffic for 20 euro. Maps are from TT, and so is the traffic info. And it's working without problems.
[MTCB Android Head Units General] Wout2426:
After a long time i tried again, with succes !

I have a old samsung i9000, and i installed a 5.1.1 rom on it.

Installed Tomtom, signed in and made a backup with Titanium backup.

Installed Titanium backup on the head unit, with backup folder on the gps card, copied the backup folder from the i900 to gps card.

Tomtom go showed up in the backup list in titanium, restored app and data.

Copied the android/data/com.gplay blabla (with the maps in it) to internal storage android/data/blabla.

And: tada !! It started ! I'm logged in, titanium restored my account, unlimited till 2018.

Only thing, i can't download maps in the app, and there is no traffic info, but it restored my destinations via cloud.

Hi.

I need your help....

I have rk3188 android radio with 4.4.4 and i trie to install tomtom, but i have the information "No network connection. Check your network settings and try again".

I root my radio and install super user, then i install Device Faker Plus - [Xposed] v1.1.0 and Phone+Id+Changer+Pro+v1.5.2, after this i search Xposed option in menu to activate option device faker and option id changer, but i dont have Xposed option.

Can you tell me what im doing wrong?

My second question is:

In your video i see that you have in screen / top right screen power botton to rebbot sytem can you tell me where can i activate this ? for i reeboot my unit allways i need after i install the aplication.
[MTCB Android Head Units General] BrokenSpring:
I can confirm the solution works fine on my 7" MTCB unit, on Malaysk's laest.

I am also trying a new firmware and will be testing the solution tonight.

Does anybody have the latest TomTom GO apk so we don't have to use the device faker app? would make things much simpler.
