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

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
[Other SmartWatches] EASolana:
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://xdaforums.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.
[Other SmartWatches] FlamingPumpkin:
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.
[Other SmartWatches] EASolana:
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.
[Other SmartWatches] FlamingPumpkin:
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 )
[Other SmartWatches] EASolana:
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.
[Other SmartWatches] FlamingPumpkin:
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.
[Other SmartWatches] JF@Menton:
Hello,

Did you connected with a Chinese Sim card and then changed it to a foreign one?
[Other SmartWatches] EASolana:
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.
[Other SmartWatches] FlamingPumpkin:
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
[Other SmartWatches] EASolana:
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.
[Other SmartWatches] FlamingPumpkin:
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
[Other SmartWatches] EASolana:
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.
[Other SmartWatches] FlamingPumpkin:
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)
[Other SmartWatches] FlamingPumpkin:
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
[Other SmartWatches] FlamingPumpkin:
Yes! I did it!!!!!! Woohoo!!!!
[Other SmartWatches] EASolana:
These are the operators that i have tried in HK.

China Mobile

Name: CMHK

APN: cmhk

MCC = 454

MNC = 12

MMSC = http://mms.hk.chinamobile.com/mms

454 07 Unicom

454 11 Hongkong Telecom

454 00 CSL

454 16 PCCW

454 06 Smartone-Vodafone

Attached is the DAT file.

Where you got the source code from?

[Other SmartWatches] EASolana:
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.
[Other SmartWatches] FlamingPumpkin:
It looks, like watch reads MCC from SIM, compares it to preinstalled (460.466.454), if it passes, it gets APN and WAP settings from firmware depending on MCC MNC combination.

So i have edited in HEX editor MNCMCC from 26001 to my 25501 all China Unicom apn wap and mms settings (keywords for HEX editing: wap, mms, net, uni), and managed to activate the watch
[Other SmartWatches] FlamingPumpkin:
Have you succeeded?
[Other SmartWatches] EASolana:
The devices I activated in china have been working perfectly.

Both the 2 devices I'm trying to activate directly in HK I have not been able to. Since the MCC 45412 is already there on the ROM if I modify, it is not able to correctly read the parameters and connect, there is one lock that I'm not able to pass.

And after looking into the NVRAM to see what is the variable that is updated to allow the devices to connect I can only find the [MENTION=1730534]settings[/MENTION] directory on the bind and bootup files. when I add the bind file, now the device will act as it was bound to a cellphone account and even try to send messages. But still no connection.

I think part of the problem is either on the proxy for CM HK, 8080 or that the wap settings are not being fully recongnized, since the peoples.net has no wap settings.
[Other SmartWatches] FlamingPumpkin:
Use ATD command to check, if your device is registered to network (dont forget about ";" at the end.

Check your operator for native 2G support (inter roaming is a problem, as your sim has one mccmnc, and active network - other)

Check, if your operator has an option to connect to network with incorrect APN parameters, or without parameters at all. In Ukraine and Russia we have such option. It helps alot, when watch uses incorrect APNs and other settings
[Other SmartWatches] EASolana:
Thanks,

So far the device reports to have the current network as active, so it is capable of seeing the MCCNC, it can select it, so it is active, but it has not been able to become registered. The weird part is that both devices, the one with connectivity, and the one without both show the same status.

the ; is used on the configuration file? after setting the proxy and apn settings?

I will also check if the device allows for conection with out correct APN settings. or parameters at all.
[Other SmartWatches] FlamingPumpkin:
Nonono. Forget about NVRAM. It is all about firmware.

Check if PIN code request is deactivated on your SIM

The only way, you can check, if your watch is really connected to network is terminal command. Try to call somewhere from your watch. Command is "ATD+380509876543;"

fill in your number. Any supported in your country is ok. I also can call the same number with other phone number format "ATD0509876543;" dotcomma is urgent
[Other SmartWatches] EASolana:
I can make the call using the ATD command, in HK, China Unicom does not support 2G, and the only option is China Mobile, so I guess connectivity issues come from Proxy settings. Since the device does appears to be connected.

The sim card does not have any pin settings. and I use the same settings for the unlocked device and it connects inmediatly.

Have you upgraded your device?? the new firmware is a lot different than original one.
[Other SmartWatches] FlamingPumpkin:
No. Updating fails all the time.

I saw updates from T08 to T12 and T12>T13, but they can't apply.

What is your current firmware version?

And please describe noticable differences.
[Other SmartWatches] EASolana:
This is the FW13 update ROM. You should be able to flash and also compare differences.

For my device, I'm now quite sure I messed up with something else. Today I'm in China and have both Unicom and CMobile sim cards, correctly connecting to the 46000 and 46001 networks, fully capable of making calls. But still the device will not get internet access. So either I erased something I should not have, or I have input duplicate parameters, that avoid my phone being able to connect.

I have tried the original rom and also FW12 and FW13.

I will do some more debugging, but so far the other unit is working perfectly.
[Other SmartWatches] FlamingPumpkin:
Also there is latest app here http://apps.imiwear.com
[Other SmartWatches] EASolana:
For the ones still bumping into this thread.

New firmware and APP for both the Watch and the MiniGPS tracker now allow to have APN settings applied directly from the APP.

The new firmware has enabled the device to receive a SMS with the configuration settings. The SMS will contain the IMEI number, APN name, Proxy, AccountName, and webpage for the APN.

You can send this message directly from your phone without the need to previously activate the device. You should be able to replace the info on the format bellow to have the device update the APN. this should work for all GPRS APN settings. I cannot test since my device is correctly connecting to the network. If someone has a device and still has not been able to enable we can try.

From the format bellow, replace all XXXXXX with your correct information

id=XXXXXXXX,apn=XXXXXXXX,proxy_port=XX,accountName="XXXXXX",homepage=http://"XXXXXXX.com.cn",
[Other SmartWatches] FlamingPumpkin:
Thank you for actual info.

But my device is not updating firmware. I have tryed everything, different ways of updating, but nothing helps. I need a file with new firmware to flash it, but i can't get it anywhere (

If you or anyone else can make a romdump with new firmware it would be great for me.

Hello Prem,

Please do you have a nvram.bin backup of the phone? SIM is not usable on my phone anymore because of invalid IMEI, could not read my SIM IMSI plus radio is off. I'm in bad need of the nvram.bin to get off this nightmare. Can you help?
[Android General] PRemBh0i:
Hi, and sorry for a late reply, But you can just get the IMEI via the wrapper on the back of the phone (Where you put the battery) and use the MTK Engineering Mode opener app from Playstore to Put the IMEI in working condition.
