Hi all,
I am a bit new to this forum. So my apologies for any tips that i have not known yet
I got a note 4 from SK telecom KR (SM-N910S) unlocked verion running Octa core version. There are 3 issues currently exist on my phone. I am living in Australia btw.
1 : Every time the phone start up, it will ask me whether i want to enable networking or not and talking about roaming ??
2 : Sometimes MMS can not be sent, retry few time and its ok ?
3 : The networking on SM-N910S has a big issue for me, that model only has 2 kinds of network LTE/3G mode or 3G Only mode, on AU version we have GSM/WCDMA/3G/LTE etc so it look like i am missing WCDMA and 2G networks
My question is :
* How can i access the hidden menu for Note 4, i know there is a hidden menu somewhere on that phone allow me to change network mode
* Can i flash my phone with AU firmware to remove roaming message and other SK's stuffs. ??
I can list some of my phone info here

Hi,
For me is not working. I did that change, I have LTE connectivity (not 4g as I have on my note 3) but now I can't use the phone, only Internet. Any idee? I'm on Vodafone Romania.

4G and LTE is just preference in naming. If you choose 'LTE' option without 'preferred', it will fail to fallback to 3G to make a phone call. Different story if your carrier has VoLTE

note 4 hidden menu network settings
I got this note 4 off ebay and it kept wanting to roam, and not use my network preference. I went into the hidden menu and changed it to all LTE and it asked if i wanted to use my network data and i said yes. Fixed it and the roaming "r" went away, but......................it won't stay like this after you reboot the phone, it goes back to roaming again until you go back into the hidden menu and do it again. How can you get it to stay permanently?
Please somebody help to modify firmware to enable international GPRS connections
What we currently have:
1. Mi Bunny Watch Q is Working on MT6261 SOC
2. Operating system is modified 2011 year Nucleos RTOS, which was widely used in older featurephones
3. Firmware is not available for separate downloading. Watch updating is OverTheAir (via Bluetooth connection from your smartphone with original APP, and, PROBABLY via GPRS connection) firmware files are called
SH08_PCB01_gprs_MT6260_S00.MAUI_11B_W13_08_MP_V15.bin
My current firmware version is MAUI.11B.W13.08.MP.V15
updates are downloaded from http://upgrade.imibaby.net/upgradeWatch
also you can find http://sw105-online.imibaby.net/ link in firmware - probably for watch activation
All we have now - full ROMdump of my watch divided to parts with Readback Extractor mtk
Also we can get acess to NVRAM and FAT partition with MauiMETA_v9.1635.23 tool (you need NVRAM database file for MT6261 chip - i've gt one from Keneksi X8 firmware kit ( or from official site ) also i have used scatter file from Keneksi to download ramdump with SP Flash Tool
Also there is good tool Binwalk which i don't know how to use well
4. Watch activation procedure looks like: ( english user manual for similar product )
-turn on the watch (lights on and sound prompt)
-insert SIMcard (sound prompt)
-----------we are currently here------------------
-GPRS connection is automatically established
-and watches time should set up the time (you get a sound prompt) /what notifies server of pairing ready status/ - this should be a sign and confirmation of successful internet connection
-you scan QR code in your user-manual (smartphone receives pairing settings from server) and establish connection between smartphone and WATCH
...
5. Watch officially supports only Chinese SIM cards. Confirmed by manufacturer. Chinese cellular operators settings are preinstalled. MNC MCC and APN can be found in firmware like 460 46000 46002 46007 etc
i have tryed to change MCC and MNC to my operators (25501) (my operator supports any APN so i got luck here)
and have got a breakthrough here - watch began to establish GPRS connections via "internet" APN
but no luck - time is not set up, i've got no "successful connection" sound prompt, and it is still impossible to activate it.
I have contacted manufacturer via Weibo and WeChat.
Everywhere i got refused with corporate security reasons, BUT at the very beginning i think some very helpful manager answered and tryed to give help (later he disappeared)
He requested from me to fill up XML form with my cellular operator's settings and sent image explaination
Hello,Mr Pumpkin
There is some instructions you can follow.
First,please make sure the sim card support calling in or calling out.
Secondly,be sure the sim card supports 2G GPRS connection.
You can consult the local operators about specific parameters.
The "code" parameter and "apn" parameter in the following table must be filled in correctly.
The other parameters are alternative.
Code:
<?xml version="1.0" encoding="UTF-8" ?>
- <Account>
- <AcntHdr>
<AcntVer>1.0</AcntVer>
</AcntHdr>
- <AcntBody>

There is excellent site with lots of information
https://www.dr-lex.be/hardware/china_phone_flashing.html
Also some discussion is going on MIUI forum and russian 4pda forum
International Apn settings
The answer from the Chinese manufacturer is an xml file that we should add to the device ROM. It is not so different to the following thread
https://forum.xda-developers.com/showthread.php?t=2387346
I have my bunny watch 2, that I have paired during a visit to Sz, and will try to add the xml file today. Hopefully we can get a connection.

Excellent desicion! I will try to do it.
I can assume, that developer didn't offered me this thing because we actually don't have access to ROM. We can get there only with MAUI META tool. Also the watch is not based on Android, so we will have to find correct folder to place the file and guess correct name for it.
Also XML should be specifically formatted, and we have this format from developer.
Easier said than done, but still I got some progress today.
After reviewing the ROM I was able to find several At commands to control the device.
I'm missing the sintaxis on many of them, but I was able to directly perform and receive a call from the Hyper terminal.
I named the xml file default.xml and placed on the root directory and several others but no luck achieving a Apn configuration.
Also I browsed the fat and nvram looking for hints on how the device was configured while using the Chinese card, but no luck there.
If I'm able to find the device configuration At command it should be pretty straightforward.
Just as a note, the App is fully Chinese, no options on the menu are translated.

Some of terminal AT+ commands work excellent (like ATD Most interesting one is AT+DEBUG_ON and AT+DEBUG_OFF it changes usb connection type. ( With debug on you will get 2 usb devices (usb com, and modem)
About app - i have translated it to russian, if it can help )
Connecting outside of china
Well, today I got connection from outside of China.
I played with several of the At commands that were supposed to actually configure the settings, and all seemed to make the terminal hang.
But after rebooting the phone it got a connection. Now it's fully working.
I used the AT+CGDCONT command.
Then I reviewed again the Fat to look for changes and the only file that was modified is store_info. Dat file.
That file was loaded in the same back up you made, with China Mobile settings, and now mine has got the unicom settings.
For the information it contains it looks fairly similar to the format the engineer gave you a solution for.

Excellent news. Now i just would like to have some more details, on how i could repeat your success.
AT+CGDCONT is not working for me - no answer from watch to this command.
Can you provide some more info. What MCC and MNC does your cellular operator has? What version of firmware do you use.
Did you actually implemented any changes to your firmware?
Which terminal software do you use? Which COM device you selected? Was DEBUG mode active?
Or what should i do to get my watch connected?
Thank you.

Did you connected with a Chinese Sim card and then changed it to a foreign one?
So I first activated my device in China with a Xiaomi Sim card.
Then traveled back to Hk, and tried with Hk local China unicom, China Mobile and three Sim cards. None worked.
Then I tried the at command for setting up the Apn settings on the device. The commands would not give an OK response, so I do not know exactly which one worked.
Then rebooted the device, and it can connect with Three and China mobile cards. UNICOM still not working.
I saw the change in the file mentioned above. It changed from one operator to the other.
HK is not so far from China, so i think there could be native support for your operators.
Anyway, could you please provide other then China Mobile store_info.dat file from your FAT partition, and a ROMdump to compare. I think you have a more fresh watch firmware. Thank you
Today I'm in China so I will not be able to upload the files to a G drive location, tomorrow I should be able to upload them.
I have bought a new device today (this time the mini GPS, 6261 based) and done a backup before the network registration and after.
I can confirm that all changes are happening to the file named "store_info.dat", and all the new data is matching to the xml format you were given. But written on a low level way inside the .dat file.
The GPRS - APN settings are independent of the GSM settings. So you will need 2G settings for your local operator, be sure you are registered in the network by performing a call to your SIM Card number then modify the store_info file with your specific operator parameters. Be sure to do this on the Hex editor so file length is constant after your perform the modification.

I am bothered with MCC and MCC settings. All i can see in DAT file is apn for internet wap and mtp, but no readable data about cellular operator
Update: i have sniffed through the firmware again, and i got that China, Hong-Kong and Taiwan are natively supported by the watch... Probably you will get some problems with diferrent cellular operators, but all 3 MCC codes 460 466 and 454 are in firmware
If you keep looking in the firmware, just bellow the MCC codes you will actually find the APN settings. Keep searching to the bottom of the file and you will find the W. A. P... U. N.I.C.O.M... C.H.I.N.A...M.O.B.I.L.E part of the string, that means that beside replacing your MMC on the top of the file above by replacing the 460, 466, 454 codes, you also have to look toward the end of the file and replace the 460000, 454000, 46600 codes with your combination of MCC and MN settings.
Since you cannot add length to the file, remember to find an operator WAP setting that will fit in the current.

all of them? - i was trying all of this, except editing DAT file
Please, share your DAT file
Also please, tell me MCC and MNC of your HK cellular network, on which you have managed to make everything work (perferably for the first time with your watch)
By the way, sniffing around MTK6261 source code led me to interesting things
setting are really preinstalled
custom_config_account.c file from "Source_code_of_6261\code_6261A_L1\custom\common" gives a clue.
I think for now - i have to chose one cellular operator, and fix all it's settings to fit my needs
Yes! I did it!!!!!! Woohoo!!!!

Time to sum up progress.
Activation option #1
Have your Chinese Seller activate the device using a Chinese Sim card before shipping, and this should ensure full communication in China, Hong Kong, Taiwan. (460.466.454) and possibly in the following places:
208 - France, 404 - India, 405 - India, 454 - Hong Kong, 455 - Macao, 466 - Taiwan, 502 - Malaysia, 505 - Australia, 510 - Indonesia, 515 - Philipines, 520 - Thailand, 525 - Singapore.
Given that MCC codes for several operators in those countries are included in the list inside the FW.
If you are choosing this way, you need to remember the device is only 2G - GMS 900/1800 compatible, so before you waste time, ensure you carrier is compatible. Australia has just dumpled 2G support so don't even try.
You can execute the following AT code before purchasing the SIM card, and it will tell you the carriers that the device could possibly connect: AT+COPS=?
It will reply the MCC Codes and operator name, with that information you can look for a valid unlocked and activated sim card.
Since device was activated in china it will easily go trough the regular process of scanning the QR code and adding the device to your APP.
Activation Option #2.
Modifiy the MCC parameters inside the FW and include your specific operator details.
FlammingPumpking, you can help us comment on how you succeed with activation.
hi all,
I decided to do my first post as i am stuck with something i am not sure how to rectify as a newbie in the android world but not newbie in the computer world.
I bought a samsung s4 GT-i9506 secondhand phone with damaged usb port thinking to repair it and try my skills for interest above all.
So got the port replaced and mobile charges ok now, i see the device working. battery is OK.
I think the device is Samsung Galaxy S4, and UNLOCKED possibly 2013 model GT-i9506 Black.
I found on the web some other codes like VDS or Shv-e330s-510 but not sure if these mean GTi9506 or are similar.
I found how to wipe - reset to factory, did that and did all updates to the phone. I dont know what OS was previously on the phone.
I then found the IMEI and paid via ebay to do a device or carrier check and got the following results including some other i add by myself.
I give all the info further down.
So, i tried to put a sim card and got error with SIM network unlock PIN window.
I added sim card, local card without subscription Lyca or comviq for above issue.
I dont know the pin and i click dismiss instead of unlock.
So, i need to unlock the networ i understand.
The paid check said unlocked so not sure what is going on with the phone at this stage.
After searching online I went in networks and did a search. I got results as below:
Telenor SE
Telenor SE
Tele2
3 SE
Telia S
So no Lyca or Comviq listed or not sure if ie Telia handles Lyca (I think Estonian company)
as i see Telia signal on the mobile from time to time, using the Lyca sim card.
I then found a video how to enter the service menu to do unlock of the network for free.
It works when i do the 0011 dial with star and hash keys combination, but does not accept
entering key values ie 1 etc to bring the next menu up etc. So it stays in the first service mode screen
which says (some items change values while this mode is on)
RRC:idle band8
mcc-mnc 240-02

speechver FR FR FR

imei certi NA
-----
So i abandoned this operation and tried to follow other videos ie to root device
and run an app, i forgot its name, found in XDA as apk file that does this unlocking as well (may work)
as could not find it in google play store.
I downloaded a root checker app and checked device. It said may not be rooted or need to grant SU permissions.
I got another root checker and said that device may not be rooted ok, but i guess could be same issue as above.
I also read that samsung disable the service mode and maybe my update is not allowing this mode to work and needs root
or flashing earlier OS versions which i have no clue how to find and apply - i have no instructions at all.
Then i tried to find free root apps but no luck as not sure what you do after that and where. So i stopped here and thought to
ask in the forums.
So, which is the best way to free fix my network problem on this oldie phone...
How can i downgrade and or flash to an older android version that will allow me to run the service mode OK etc. what do i need for that.
Platforms and software pc or mac.
I have a soldering iron and screwdrivers and may do some soldering if is possible to my skills.
