[Q] *#*#4636#*#* not working

Hey i want to change my phone to WCDMA Preferred by using *#*#4636#*#* but when i am trying to use nothing happens?

'Hidden menu" on our note 3 is not enabled...
you need to be rooted...
And you'll need Root Explorer...
Go to file EFS/Carrier/hiddenmenu
Open with root explorer text editor
You will see the word "OFF"
Delete and type in "ON"
Use capital letters
Hit the back button "you have made changes to this file do you wish to save?"
Click yes
Reboot
You now have your hidden menu but I don't know if all the codes are the same as previous Samsung devices... I don't mess with it to much... I just used it to turn off the wifi power saving mode.

Is there any way to access it without rooting the device?

Not anything that I know of...
If you go to a Best Buy store when the Samsung specialist is working... they are supposed to be able to plug in and enable that menu to do their tests before giving you a warranty claim... maybe if you found one of those dudes and bought him a beer?

Yes rooted, omega 4.0 mj7

I had the same problem, the folders did not exist. I did a search for hiddenmenu and it found nothing. Then I checked the EFS folder again and everything magically appeared.
Rooted, using Hyperdrive ROM

If your rooted try "advanced signal status" app on the playstore... Works great and easier

Answer
Just try *#0808#

No need to enable the HiddenMenu anymore.
You can use 'Phone INFO ★Samsung★' app --> go to 'Secret Codes' menu, or use 'Shortcut Master' app --> go to 'Secret Code Explorer' menu to launch the secret codes (ROOT is required).

Wi-Fi disconect automatically - erro

Hello guys, I have a Galaxy Y Duos Pocket Neo model GT-s5302b.* It features the following defect: when I try to connect to Wi-Fi the icon lights up but it is just a moment and automatically turns off.* The device does not find any network. I thought it was a defect in the hardware, however it was not. Now I believe it is the ROM update that caused this defect.* Someone could give me a technical solution for this.

Sm-c115l work as sm-c115 world

It may some of us need to have K zoom SM-C115 world on the Zoom 2 SM-C115L, then please followings:
1. Flash by ODIN system file from the link: https://drive.google.com/file/d/0BwmQ3F48xaJjaHV1VV9xRmVwTFU/view?usp=sharing
2. Phone will auto reboot.
Everything is OK, except Wifi lost password after every restart, so you could:
3. Flash by ODIN TWRP recovery (including Supersu installer) from the link: https://drive.google.com/file/d/0BwmQ3F48xaJjMWdXVWJUUDZrX0k/view?usp=sharing --> auto restart phone --> connect to internet to install Supersu --> restart --> ROOTED.
4. Copy “build.prop” from the link: https://drive.google.com/file/d/0BwmQ3F48xaJjVHhxdFd6MkpCOVE/view?usp=sharing --> Replace the existing one in …/system/ (set permission for the new “build.prop”)
5. Boot into recovery (press volume + and home and power button) --> wipe phone --> restart the phone.
YOU ARE DONE, YOUR PHONE BECOME SAMSUNG K ZOOM SM-C115
GOOD LUCK!
Thanks to 5up.vn for TWRP recovery

ok cool !
the Wifi lost password after root and change the build.prop or work normaly ?
thank you

The wifi password lost after every restart, then you have to root your device to replace new build.prop for the existing one --> everything is ok!

hmm, i was install (fleshing) this it was work but can't recive any call signal can u check that?

Many thanks.
I've done it, but can you tell me if your 4G still working after ?
I'm now unable to run 4G
I'm wondering if it also able to get 4G+ on it ?
Tks

After Replace last step
After Last step .Restart with nothing show on screen

video
can you make a video to show how to do this installation...

Thanks for the post. It saved a lot of time of mine. But I think there is a minor flaw in the instruction. In No.3 the does not get rooted as you described, you have to install SuperSU binary to get root access. Otherwise, everything is good.
I'm still facing one problem though. When I insert a new SIM or restart my device I can not make calls or receive SMS untill I make random switchings in Settings> More networks> Mobile networks> Network mode.
And I can't turn off Haptic Feedback. Any possible solution???

ZUK Z2 Pro Guide to Everything (OTA, Unlock Bootloader, ROOT, Widgets, Gapps)

Hi Folks
I just went through personalizing a brand new ZUK Z2 Pro Z2121 and found a lot of information scattered around the net which I tried to summarize here.
First I noticed my phone was not on the latest Firmware/ROM but the Update function in the settings would not show the SW 2.5.355 to be available.
#-#-#-#-#-# Section 1
Upgrade to 2.5.355
If your phone shipped with something less than the latest Firmware (as of now SW 2.5.355) you may want to update over the air first thing.
The problem is that you need to be in China to receive the update.
Solution:
Install a Free VPN App
(e.g Hola VPN - you will need Google Playstore first - install Playstore via App Center than search for VPN in Google Play)
Select a Server in China
Go to Updates and search for updates. If an update is found download will start.
Unfortunately this may take forever as you are probably using a free VPN server.
But the OTA Tool is not very smart.
If you terminate the running VPN connection while the download is active the download will briefly stop, but then resume (without the VPN).
10min later you should be all set.
#-#-#-#-#-#
Now that you are on the latest SW you may want to unlock the bootloader.
#-#-#-#-#-# Section 2
Unlock Bootloader
Unlocking the bootloader is required if you intend to root your phone.
It will wipe all user data, therefore I recommend to do this first thing.
On your phone go to Settings -> About -> Status to note your 8 digit serial number.
If your serial has less than 8 digits add zeros to the END to make it 8 digits.
While you are in Settings , Enable the Developer Options by going to
Settings -> About and clicking 7 times on ZUI Version.
Then go back to Settings -> Advanced Settings -> Developer Options and enable USB debugging.
We will need this later.
In order to unlock the bootloader you will need to got the zuk website, where you need to register first before you can request to unlock the bootloader.
So go here:
https://passport.zuk.com/wauthen3/wauth/jsp/register.jsp
(use google to translate)
Select Email Registration (upper right corner) and fill in the required data.
Likely a Googlemail Address will not work.
You will receive an Email with a confirmation link.
Now that you are registered, log in and than go to
http://developer.zuk.com/bootloader
(use google to translate)
Click on Carry On.
On the next page select your phone type Z2 Pro.
Enter your serial nuber (8 digits)
Enter an email address where to send the unlock image. It seems that the email address here has to follow some rules.
[email protected] or @Web.net seems to work. A domain name with a hyphen (-) seems to cause problems.
Check the 2 check boxes and click SUBMIT.
If succesful you get a message that the image has been sent to your email address. No message means something went wrong. Likely the email address was not approved.
I had some trouble here at first.
Next things is to get ADB/Fastboot installed on your PC.
All you need to know is found here.
https://forum.xda-developers.com/showthread.php?t=2588979
Safe the email attachment from ZUK you requested earlier (named unlock_bootloader.img) into the directory where adb is installed. (likely c:/adb)
Reboot into bootloader by:
Opening a Command Window and CD into the directory where adb is installed.
Do a
Code:
adb reboot bootloader
If this fails you may need to confirm USB debugging on your phone and try again.
Once the phone is in bootloader mode continue:
This will wipe your phone!!! Factory Reset !!!
Do a
Code:
fastboot -i 0x2b4c flash unlock unlock_bootloader.img
The response will look like this
Code:
target reported max download size of 1610612736 bytes
sending 'unlock' (0 KB)...
OKAY [ 0.031s]
writing 'unlock'...
OKAY [ 0.063s]
finished. total time: 0.094s
C:\adb>
Do a
Code:
fastboot -i 0x2b4c oem unlock-go
The response will look like this
Code:
...
OKAY [ 0.031s]
finished. total time: 0.031s
C:\adb>
You may need to do a
Code:
fastboot reboot
after this.
In my case the phone rebooted itself.

Once the phone boots up it will be in Chinese again.
On the welcome screen tap the bottom of the screen below the highlighted blue text to skip the ZUK login.
To change the language back to English go to Settings.
In the third section choose the last entry. "Advanced Settings" (the gears symbol).
Choose the 2nd menu item.
Choose the first menu item and select English.
While you are in the Settings Enable USB debugging again. See Above. We will need it for the next step.
#-#-#-#-#-#
As a next step we will ROOT the phone by using a TWRP custom recovery image.
#-#-#-#-#-# Section 3
Rooting
I was a bit uncertain if the TWRP image is stable or not, therefore I decided not to flash it, but only to boot into it.
So I use it temporarily only.
First get SuperSU from here
http://downloadmirror.co/Utz/UPDATE-SuperSU-v2.79-20161211114519.zip
and copy the ZIP file onto your phones internal storage.
Get the recovery here.
https://www.androidfilehost.com/?fid=24591000424960393
Save the image file in the abd directory.
Do a
Code:
fastboot -i 0x2b4c boot recovery-TWRP-3.0.2-20160712-ZUK_Z2_PRO-CN-wzsx150.img
The phone will now boot into recovery. Chinese at first.....
Click on the lower right button to change the language to English.
Click on the lower left button to keep the system read only.
On the next screen click install and navigate to the SuperUser.Zip File that you placed on the internal storage.
Confirm the install and finish rebooting. It will do a short loop and than boot up correctly.

https://forum.xda-developers.com/zuk-z2-pro/development/twrp-recovery-zuk-z2-standard-pro-t3415395
#-#-#-#-#-# Section 4
Get the Google Stuff to work.
Install Google Play.
On the home screen click on App Center. Select Go to Home Screen.
Search for Google Play and install.
#-#-#-#-#-#
Install Google Contact Sync & Contacts
Thanks to Lucaam pointing us to this
https://forum.xda-developers.com/zuk-z2-pro/how-to/google-contacts-import-sync-t3462124
Install Contacts Sync and Contacts out of the Lenovo_Zuk_Gapp_6.0.zip File in that order.
Thanks to m_atze
Play Store I did already so I don"t use that APK from the ZIP.
#-#-#-#-#-# Section 5
Custom Launcher
Installing a custom launcher seems a bit tricky, as you can not permanently set the new launcher as the default.
You can try in Settings -> Advanced Settings -> Applications
At the very bottom you can find the Preferred Apps section.
Set your Launcher as preferred.
This did not work for me.
Workaround: Install Google Now Launcher from the Playstore -> Open it -> Follow the dialog to Settings -> Select your Launcher - Press Home
It basically takes you to the Settings -> Home which is hidden in the ZUK settings
De-Install Google Now if you don't want to use it.
#-#-#-#-#-# Section 6
Widgets not updating or being empty.
There is an App pre-installed called SafeCenter. It has pretty tough autokill rules, which kills the processes / services needed to update the widgets.
I decided to diable SafeCenter completely, for which I had to use a separate App. The Disable functionality in the settings was not active (grey).
You can use several Apps from the Playstore to do this. I use one called SystemCleanup.
While you are at it. Disable Bug2Go -> according to the internet some tracking/spy App used on Motorola phones before.
#-#-#-#-#-# Section 7
Adblocker AdAway
If you want to use an AdBlocker like AdAway which modifies the /etc/host file you may run into isssues that the Adblocker can not mount the system partion read/write.
In that the host file maybe put into a different location. (e.g /data/hosts) and the original file must be replaced by a link.
Make sure you still have USB debugging enabled. Open a command window and change into the adb intall directory.
Do a
Code:
adb shell
followed by a
Code:
su
Grant permission to adb shell for root access on your phone.
(The command prompt will change from $ to #)
Do a
Code:
mount -o rw,remount -t ext4 /system
to mount the system partion RW.
and create the link with
Code:
ln -sf /data/hosts /system/etc/hosts
In this case I assume the Adblocker will place the hosts file in /data.
Check or Set in the settings of the Adblocker the correct location.
You should do a
Code:
mount -o ro,remount -t ext4 /system
to change back to a read only system partition.
I had to reboot to make everything take effect.
This has been tested with AdAway.
#-#-#-#-#-# Section 8
Finally the Notification LED ....
I am still looking into this, but it seems that the post from Florent here
http://zukfans.eu/community/threads/notification-led-multicolored.275/page-2
provides a solution / workaround. I will provide an update here later.
I hope this is helpful to some of you. Let me know if things can be added or need corrction.
Cheers Ulf
BTW How do I place the attachments (pictures) into the text where they are relevant?

Brilliant write up! Thanks.

Great tutorial! I think you should mirror the tutorial for the Z2 (Plus) section, since it works and there isn't one as complete as this one there! Congratulations!
If you have time, you could also cover custom roms, especially because our phones are ARM64, unlike the majority

did what you said about updating phone. got no update and i'm on ZUI version 2.5.335 ST. is your version just a typo?

When I want to register for unlock the bootloader I get a timeout message in chinese. Is this a known error?

waiting or device
waiting for device
i had to install a fresh windows 7 64 bit version to be able to use fastboot ..
download the zuk z2 pro drivers <- search string google
install adb drivers
after connecting windows promptet me for installing the lenovo bla bla drivers
and i was merily on my way
for mee ik took 2 days to come to that point so i hope this is of help for those who have the same problem on win 10 no dice also after clean install

Thanks to the OP for such a detailed guide.
With regards to unlocking the bootloader, has anybody had success recently using developer.zuk.com?
I have tried multiple times and keeping getting an "Bad Gateway" error.

Hello to all,
I installed the zui 2.5.435 st, after I followed the instructions to have the root permissions.
I downloaded supersu, and started installing via TWRP, the problem that the phone has never restarted. Remains with a black screen.
I tried twice but nothing to do, i have to reinstall the zui from head to have the working phone.
Give me a hand to have root permissions and to increase the translation of the phone into Italian.
many thanks in advance

Hello,
The solution on OTA is not working on my device. I do not have the system update option. Please help. Thank you!

I'm not receiving the e-mail. It gives me the message e-mail has been sent, but there's nothing in inbox or the spam folder. The registration confirmation e-mail had arrived immediately.
I have tried using a gmail adress, a gmx.com one and a disposable e-mail, but none of them are working out. Any suggestions?

For anyone having issues, e-mail your phone model and serial number to devworld{at}zuk.com
They sent me the image quite quickly.

Thank you, I will try this. The link in the first post no longer works....
Edit: I went to the unlock bootloader page, entered everything and was then redirected to the login/register page. It was even possible to switch to English. From there on it was a straight forward procedure, and I quickly got the mail with the bootloader image

Does OTA updates still work if you unlock bootloader and root the phone?

Hi, is position travel app in this zui version? (settings - >advanced - > lab features - > position travel?) or is it no longer there? Thanks!

Consider before taking a post here and please make sure whether you are writing in the relevant thread!
Check your device configuration if it relates to this thread. If not please dont facilitate the proliferation of misinformation, otherway please feel free to share your knowledge and experience or take a question.
I feel the neccesity to create a separate thread for this version of HU since it makes always confusions whether the revealed information relates to the owners device or not. On the other hand some of the applied methods are way more different compared to the PRO series that mainly derives from the differences of the UI thus this thread will ease that confusion.
That is why i will share here all the methods of troubleshoots i have collected so far.
Basic codes:
Settings ==> Car Settings ==> Extra Settings ==> 8888 (restricted settings)
Settings ==> Car Settings ==> Extra Settings ==> 123456 (advanced settings for left panel touch controls and ect.)
Settings ==> Car Settings ==> Reset Factory ==> 7890 (wipe data - all 3rd party app. will be deleted)
Settings ==> System ==> Developer Options ==> 7890 (usb debug and ect.) ==> USB debug Pw.: [email protected]
Advanced Developer options:
Settings ==> System ==> Developer Options ==> 7890XX , XX=Current time in hours 24hrs format. If its 7 o clock in the morning then the code is 789007
Do not try any of these codes with no reason and without the adequate knowledge!!!!
If the HU is working well forget it!!!!
Use these codes only on your own risk and reponsibility!!!!
TO BE CONTINUED
Follow on topics:
- Method to force update and wipe data cache as a solution of a boot looping.
- Setting up the left touch panel including button lights activation with color change.
- Method of installation and activation NEXAI Toppal AI (key not included, must buy)
- Firmware update method.
- BT issue

Method to force update and wipe data cache as a solution for boot looping.
Right now there isnt any known method for this version of the HU to restart in recovery mode to make a wipe cache but . . . .
There is a working method to force the HU into update mode even if it stucked in boot loop.
-Get a paperclip, needle or toothpick
-Get an USB flash drive 1-32 Gb, Format it with FAT32 file system with the default volume size as it is provided by WIN11
- Open the link (provided by JUNSUN support)
https://drive.google.com/drive/folders/1QGzYyTV2_S7W2wmr7mP3uSgsWAxzyONb?usp=sharing
-Extract the ZIP file and copy all 3 files to the flash drive root directory.
- Get in the car and connect the flash drive to the 4 PIN USB outlet.
-Put the key into the start lock and turn to ACC/Power on wait until the boot logo comes up.
-Take the paper clip and press the reset button 1x, just press, dont hold
-The device will restart and when the boot logo appears again switch the power off/ turn the key/ ignition off immediately.
-Wait 10 SEC and turn to ACC/Power on.
-If everithing went well a "green loading bar" shuld appear on the screen with the tex "UPDATING" or something similar, i could not read it properly because it was visible only for a couple of second due to the size of the upgrade files ~2kb . I think these files are something that is like ADB (Android Debug Bridge) and initiates an update recovery command.
-The update took me approx. 5 mins.
-After the update all 3rd party application will disappear, eventually its like a wipe chace.
So far this is the only known working methode to get out from boot loop without flashing the HU.
Ps.: If it does not work try the other USB outlet or try another flash drive. If it still does not work dicsonnect every cable from the HU and reconnect only the power supply and USB and try again all the combinations that i previously mentioned.

Link to Color.apk
Basicly the so callaed color.apk is a preinstalled sys. app.. With the following method you can enable the aplication:
Got to SETTINGS > CAR SETTINGS > EXTRA SETTINGS >> 123456 >> CONFIG INFO >>> tick the box, select >>> COLOR
after that the aplication should be visible. If not follow the link below:

Method of installation and activation NEXAI Toppal AI (key not included, must buy)
Installation:

Link for the NEXAI APK files:
https://drive.google.com/file/d/1tDDi05owYzdGayswq-Alj8GpKQhXZJtX/view
Activation:
Firstly you should buy an Activation code.Once you got the code then the steps are as of the following:
(1)Copy the activation code sent by the customer service, modify the SSID of the hotspot to the activation code, turn on the WIFI of the radio and connect to the corresponding activation code(SSID), and the activation will be successful after successful networking.
(2)You can enter the ‘NEXAI Voice’ application to check whether it is activated. Once the activation is completed, the voice control function will be available and the Nex(Floating Robo) will change the color.

Ps.: If it does not work try the other USB outlet or try another flash drive. If it still does not work dicsonnect every cable from the HU and reconnect only the power supply and USB and try again all the combinations that i previously mentioned.

Method to force update and wipe data cache as a solution for boot looping.
Right now there isnt any known method for this version of the HU to restart in recovery mode to make a wipe cache but . . . .
There is a working method to force the HU into update mode even if it stucked in boot loop.
-Get a paperclip, needle or toothpick
-Get an USB flash drive 1-32 Gb, Format it with FAT32 file system with the default volume size as it is provided by WIN11
- Open the link (provided by JUNSUN support)
https://drive.google.com/drive/folders/1QGzYyTV2_S7W2wmr7mP3uSgsWAxzyONb?usp=sharing
-Extract the ZIP file and copy all 3 files to the flash drive root directory.
- Get in the car and connect the flash drive to the 4 PIN USB outlet.
-Put the key into the start lock and turn to ACC/Power on wait until the boot logo comes up.
-Take the paper clip and press the reset button 1x, just press, dont hold
-The device will restart and when the boot logo appears again switch the power off/ turn the key/ ignition off immediately.
-Wait 10 SEC and turn to ACC/Power on.
-If everithing went well a "green loading bar" shuld appear on the screen with the tex "UPDATING" or something similar, i could not read it properly because it was visible only for a couple of second due to the size of the upgrade files ~2kb . I think these files are something that is like ADB (Android Debug Bridge) and initiates an update recovery command.
-The update took me approx. 5 mins.
-After the update all 3rd party application will disappear, eventually its like a wipe chace.

Do you think there is any chance this would work on a FF_866X model bassed on the MTK8667 chip?
the normal update procedure is to place the firmware update files 8667.bin and 8667.upd files on the root of fat32 usb into 6 pin usb slot, turn on and tap screen, it should show "detected" in top left corner then it updates, however my update files must have been corrupted as update failed and it seems its wiped the unit as now it shows detected but then goes to fastboot mode see pics
I have tried many different firmware versions but it just goes to fastboot, I have tried a few different usb drives and tried both the 6 pin and 4 pin slots but still nothing

Solution for Bluetooth connection issue / failure.
After installation of a third party launcher app or upon updating the firmware it is a common problem that the bluetooth connection does not work (BT device is not visible and unable to discover another device). And also if you check the the MAC address of the BT device it will be value "Null"
With the following method you can activate the built in BT device :
First you need to go into the bluetooth settings and check if there is a username and password. (Important: you don’t need to enter anything yourself, the name and password must be assigned automatically.)
Then
Got to SETTINGS > CAR SETTINGS > EXTRA SETTINGS >> 123456 >> CONFIG INFO >>> tick the box, select >>> BC6 (in some version it is BS6) >>> disable all the others >>>> RESTART
Now it should work.
If the checkmark is in the BC6 checkbox, then you need to deactivate it and put it in front of BC8.
If it is opposite BC8, then you need to change it to another checkbox, reboot the device, and do the same operation, but return the checkmark to the checkbox opposite BC8.
Restart and done ,

In my opinion your Boot Loader is corrupted that is reason why it can not be flashed.
The most valuable knowledge can be gained only on the bases of personal experiences. What i can recommend you not more just to make a try. Series of tries will lead to the success.

yes I have tried and doesn't work. I guess all I can do now is wait for the seller to reply to me
My unit just goes straight to fast boot screen no matter which firmware I put on the usb

Start to study ADB Shell and try to update it using shell commands via pc or replace your boot loader.

Dobrý den. Dnes jsem konečně namontoval nový Junsun v1 s Androidem 11 a jsem z toho rádia docela zklamán. Myslel jsem, že namontuju rádio, nastavím základní věci a budu hrát. Tak to rozhodně není. Nepřehledný, složitý, celý večer koukám na internet a teď už asi 3 hodiny pročítám toto fórum. Zjistil jsem, že RDS je nutno nastavit, OK. Logo vozu je nutno kdesi stáhnout, OK. Ale co mě mrzí nejvíc, když jsem rádio namontoval, fungovalo vše v pohodě. Ovládací tlačítka vlevo stále měnila barvu, čehož jsem si moc nevšímal s tím, že to pak změním na stálou barvu. Připojil jsem zadní kameru a vyzkoušel funkci. Podle schématu v manuálu nešla, našel jsem info, že se musím použít hnědý kabel a pak už to fungovalo. Ale pak jsem si vším, že ona tlačítko vlevo jsou potmě. Víc než hodinu jsem hledal v menu, kde by se to dalo nastavit ale nenašel jsem. Poradíte mi prosím někdo, jak to nastavit? Koupil jsem k tomu i modul OBD2, docela jsem se divil, že v jednotce není žádná apka k tomu, stáhnul jsem Torque ale ten se mi nedařilo nijak připojit. Zkoušel jsem to už dřív v mobilu, tam jsem se s ním sice spojil, ale komunikace žádná, Santa Fe CM2 2006. To ale zatím řešit nechci, teď mě nejvíc trápí ta tlačítka potmě. Děkuji za radu
Mod. Translation: Good day. Today I finally installed the new Junsun v1 with Android 11 and I am quite disappointed with the radio. I thought I would mount the radio, set up the basics and play. That's definitely not the case. Unclear, complicated, I've been browsing the internet all evening and I've been reading this forum for about 3 hours now. I found that RDS needs to be set, OK. The car logo must be downloaded somewhere, OK. But what saddens me the most, when I installed the radio, everything worked fine. The control buttons on the left kept changing color, which I didn't really notice except that I would then change it to a constant color. I connected the rear camera and tested the function. It didn't work according to the diagram in the manual, I found information that I had to use a brown cable and then it worked. But then I notice that the button on the left is dark. I searched for more than an hour in the menu, where it could be set, but I couldn't find it. Can someone please advise me how to set this up? I also bought an OBD2 module for it, I was quite surprised that there was no app for that in the unit, I downloaded Torque, but I couldn't connect it in any way. I tried it before on my mobile phone, I did connect with it there, but no communication, Santa Fe CM2 2006. But I don't want to deal with that yet, now the buttons in the dark bother me the most. thank you for the advice
