I have a galaxy note 4 and a KIA optima... The car always says "pairing failed" and I reconnect, which only lasts a few days if I am lucky...

This post is an attempt to collaborate and figure out a way to "fix" this issue...

Anyone have any ideas or anything that gas helped them not have this issue?
[AT&T Samsung Galaxy Note 4] hiverli:
replace the car :)

here is some solutions for that

I really wish I would have known about this. My Subaru Forester doesn't even recognize media over BT. Phone BT fucntionality works fine, but it won't play/connect to media at all. Both on 4.4 and 5.0/5.0.1.

Worked for my GNote 2 over various ROMs/stock, worked for the wife's GS3 and HTC One M8. It's really frustrating.
[AT&T Samsung Galaxy Note 4] renocivik:
Replace the car? Its actually a pretty damn amazing car... Thanks for the lack of good input...

Your link was for devices not connecting.... Mine connects just fine...

But, and it just happened again.... I'll restart my phone and the Bluetooth device (the KIA) is gone... Not even listed as a paid device anymore...

Hard to say that's a KIA problem...
[AT&T Samsung Galaxy Note 4] xlr8shun:
I have a 2015 kia optima lx, without the nav package or the upgraded audio. My note 4 on NIE has no problem pairing or staying paired. It pairs automatically everytime i turn the car on (I see the downloading icon on the radio). My gf's note 4 also pairs fine and works fine. The car switches between primary and secondary phones seemlesly.

And i agree. Amazing little car.. sorry i cant offer any other info, except "mine works".

I dont know what year or model you have, but maybe a trip to the dealer and ask about any firmware upgrades for your headunit. or maybe better yet a trip to www.optimaforums.com and see if anyone else is having issues like you describe.

Optimaforums has a wealth of info from fellow optima enthusiests. You might find your info there if none here can be of help.

So... Going over my issue... And want to see if others have the same issue... I may have a solution/workaround...

Basically I pair my phone with my kia stereo... It will work fine for a few days... Then it will fail to connect... When I go to Bluetooth settings on my phone, the kia stereo is no longer listed...

Do others have this same issue??

Getting specific, is it the boot.img that you find in the big .zip file that you have to boot up?

Something like:

adb reboot bootloader

fastboot -i 0x19d2 boot boot.img

...and then flash superSU (and possibly gapps)?

Hi All.

Got my device from Hong kong today, Live in Denmark so think i am the first user in Denmark of this device.

Man the screen are great :)

We are missing an forum for this device here on XDA, hope they create one for us soon, so we can setup guides on how to do this and that.

Ok could we create an process guide in this thread with links for updating, rooting and so on.

I really miss Google stuff on my device, Google Play, sync from google contacts, photos, calender and so on.

First i think i need to Root right?

When its done i need to install Google framework right?

Could soneone that has allready provide us with links, guides or mayby Youtube video on how to do it correct, i would kill myself if i Break the device on the first day.

Thanks peeps :)

Hi tuddu,

I don't know what happened, I re-installed drivers, now all is fine, at least I have been able to install stock recovery and install stock rom through disk, all fine here...but....and this is a huuuuge but.... I've got no mobile connection, no network.

On rebooting the following message appears :

“SIM card changed. The phone needs to reload network parameters, and it will restart automatically after loaded. Please wait patiently.”

- The sim works

- Contacts are read

- IMEIs are not lost

- I can make calls and receive calls

- I can receive sms

- I can do almost everything, but still, no data working.

Happy times.... one thing solved, another one appears. Incongruencies between phone and installed stock rom ?

This is getting really interesting now.

Cheers,

Ken
[Android Q&A, Help & Troubleshooting] K3nshiro:
OK, this is getting annoying...

This all started after installing Cuoco's Rom, no mobile data is available. We reverted back to stock rom 1.68 and the problem persists... No mobile data.

When booting the same message appears :

"Sim card changed. The phone needs to reload network parameters... " Even after rebooting nothing helps.

I asked in the Z9 Mini forum and they told me that it's probably a radio issue (what the F?)... and that I would need the radio files (which?) from a working Z9 and patch them...

Hello? We did everything correct, does this mean that we have an international device and flashed a Chinese rom we were not supposed to? This is somehow not acceptable... How are we supposed to know?

Is it the modem files, the GSM that we need to flash as well?

Would that help?

Very disappointed I am indeed...

Any help is highly appreciated,

Cheers,

Ken
[Android Q&A, Help & Troubleshooting] tuddu:
What about reinstalling Cuoco firmware? Try to see if the radio works back. If so, better to rest with cuoco firmware, untill working rom is out. Alternatively, in side cuoco rom there should be the radio file (where??? Which folder???) you can look for and (if fount) extract them, to be used in place of stock nubia ones. As far as I know, there ' s only 1 NX508J version in the word...

[Android Q&A, Help & Troubleshooting] K3nshiro:
Hi tuddu,

Well, it's in fact after flashing Cuoco's Rom that everything went downhill, at least that what my friend told me.

I've been able to find people with the same issue on Z9 Mini (here), apparently this happens when you flash chinese stock rom in International version...but that applies to the Z9 Mini....

I also never heard that the Z9 Classic had one chinese and one international version...I thought that only one version exists :confused:

The files that need to be patched are (for the Z9 Mini):

- persist.img,

- fsg.img,

- fsc.img,

- modemst1.img,

- modemst2.img

I've only been able to find persist.img....no idea where the rest is located, or embedded. And to be honest, I don't feel confident fiddling around with these important files on a device which is not even mine :(.

Anyway, I opened an account at Nubia and will post there, maybe I'm lucky...

Hello,

z9 classic and z9 max have the same hardware so I was thinking if it is possible to install the official cyanogen rom available only for the z9. If not, I think a port is easy to make so why nobody did?
[Android Q&A, Help & Troubleshooting] K3nshiro:
I happen to have them both at home now, and the max is clearly bigger, they only share same camera and 810 SD. The Z9 weights even more than his bigger brother.
[Android Q&A, Help & Troubleshooting] tuddu:
Ciao K3nshiro, no, I don't think Cuoco's rom is the problem... The modem driver he used are the same as stock, and the band supporter are the same also. He just traslated the menu settings into italian (and other linguage originally not supported by ZTE... unbeliveable). So, considering that the modem is just one everywhere (europe of china) I fear your friend made some mistakes during ROM installation (WIPE, etc. Etc.). Now I'm asini to myself... What happens if he now flash CUOCO's ROM again, respecting all the wipes ? It should return back working, I assume... Did he tried this (again, by following the wipes, very important)?

Inviato dal mio NX508J utilizzando Tapatalk
[Android Q&A, Help & Troubleshooting] peppebi:
I know they have different screen size but resolution is the same and all the other specs are the same. Z9 classic is just a smaller Z9 max with premium design and the bezeless screen. The only difference, but I'm not sure, is the audio dsp that should be better on the z9 classic.
[Android Q&A, Help & Troubleshooting] K3nshiro:
SOLVED !!

In case someone has the same issue, read below :

How to solve the “SIM card changed. The phone needs to reload network parameters, and it will restart automatically after loaded. Please wait patiently.” message.

1. Download beta 1.69 and beta 3.82

2. Install stock recovery through adb using the command "fastboot -i 0x19d2 flash recovery recovery.img"

3. Boot into stock recovery and do all 3 available wipes

4. Flash first rom -> 1.69

5. Reboot

6. Phone will display the same "sim card changed" message, but this time, when clicking load, it will reboot.

7. Once rebooted, network parameters work again

8. You can stop here, but if you want to continue, do the same with 3.82

9. Be happy

I tried the same with stable roms and it didn't work, it only worked with beta versions.... At least we do not have to send the phone back now ! :)

Hi, guys.

I own Nubia Z9 classic. Installed the latest 3.86. The battery drain is HUGE, it's a nightmare. I have only 3 hours of active screen now. On 1.58 or 1.68 I had more than 7 (mostly 3G browsing). Seems battery health is ok, i tested with Battery Monitor Widget. Phone is less than 1 year old.

Going to flash 1.68 by Cuoco now. Let's see...

No, haven't seen this one. Is it supposed to be beta?

I now have installed 1.69 beta... No probs with second SIM card, GAPPS are OK, too. Let's see how it would behave in sense of battery life...

BTW, I wonder why this problem with battery drain ever exist so bad on Nubia Z9? Is it something wrong with kernel, I mean CPU management? I was looking at logs and cannot find some specific reason of sudden battery usage peaks. Looks like it has to do with "Android OS" part itself...

[Android Q&A, Help & Troubleshooting] Nafiganado:
Battery consuming on 3.86 - disappointment.

At last i've decided to try 3.86. I did not install google, it was clean firmware after factory reset. I've made experiment: was browsing via Wi-Fi in power-saving mode. Outcome: 1h 7m has consumed 22% of battery that I consider unacceptable. If i would install google after - i think it would be a total disaster in battery consuming sense! :crying: So I have rolled back to 1.69 beta. Let's hope this power problem gotta be resolved in Android 6 firmware (i still hope it would come up :) )

UPDATE: i've given it a try again - installed 3.86. But it's different from description - it does not contain root! I had to root separately. And thus maybe it's not the one according to description.... Damn. Looking forward to see the one based on Android 6.

UPDATE 2: i've flashed another 3.86, with built-in root. But battery life is disgusting, too. So I'm rolling back to 1.58. I still hope battery itself is ok, because I was testing it with Battery Monitor Widget for 2-3 weeks and it shown me capacity was ok.

UPDATE 3: i've flashed 3.85. Up to 5 hours of active screen. I don't think i will squeeze more. OKAY.

nx508J Gapps

Hello all,

I just got a

nubia Z9 nx508J

. I would like to install google apps since it seems a lot of apps I use need

google services

to run.

I understood that I need to root my phone in order to do that. I tried many things :

-I found many tutorial with a PC based tool that installs a recovery and superuser in a click but unfortunately I am working on a

Mac

. I was able to run the exe file using a tool called wine but I think it doesn't work because it cannot detect the phone.

-I saw that this could also be done using adb/fastboot commands (which I don't know much about but I have installed in case) but as I don't know how to proceed I am afraid to brick the phone, plus I don't know what recovery is safe to download for this model.

-So I managed to root the phone with KingRoot (I downloaded Root checker to make sure), then I tried to install the gapps and convert them to system app with Root Explorer but again that did not work. I don't know if I did it wrong or if it is just that it can only be done by installing recovery and supersu.

As you might have noticed I don't know

anything about anything

, I just went blindly from forum to forum and tried many things and maybe done it wrong. So, if anyone that has enough patience to tell me how to do this and help me I would be very much grateful ! Or if anyone knows if any of the things I've tried should have work and then it would mean i just did it wrong, please explain me how to do it properly.

Again I just want google apps, I am not interested in installing custom Roms or make any use of root priviledge other than for this purpose, and I am working on a mac.

Sorry about so much noobness...

Cheers!

[Android Q&A, Help & Troubleshooting] K3nshiro:
U r welcome mate, remember that the recovery.img is inside the zip itself. You need to extract it first (drag & drop) to your desktop for example. Flash it through adb, which means that you need to have Android SDK + ZTE drivers installed... Just the most basic SDK, otherwise it will install up to 6gb on your HDD. The command to flash recovery later, needs to be exactly as described a few posts above.
