I don't have the Walkie Talkie 3 radio, but as far as I know, Xiaomi WT 3 is a 4G Netcom device, not a "real" walkie talkie at all, so MiPTT mod is pointless for it.

Hi darkhorse1870

Can you help me add a firmware mod for hardware version 4.6? I see we have 4.2 or 4.5, 4.8. But in my device hardware, the version is 4.6.@dar
[Hardware Hacking General] darkhorse1870:
Hi QuangVinh95

To add the firmware mod for your walkie-talkie version, I need in your original firmware dump.

Please read this thread on Github about the hardware version 4.5 firmware modding : https://github.com/Mi-Walkie-Talkie-by-Darkhorse/Mi2-XMDJJ02-firmware/issues/1 . If you will be able to repeate these steps and dump your walkie-talkie original firmware, I can add the firmware mod for 4.6 too.

many thanks for all, work and software.

just purchase a walkie-talkie 2S, and al mods instálled ,thanks yo you.

it would be Great to be able to change public chánnels and amateur.

so we could use more chánnels
[Hardware Hacking General] Govillard:
I feel something like that..

Volume level 1 is too loud, and there are no big change when I put volume control upper..
[Hardware Hacking General] damn66:
are u saying the mods works for the latest 2S as well?
[Hardware Hacking General] Govillard:
Yesss. I thought you all know it….

Yesterday I downloaded all software, thinking that it was for xiaomi walkie 2S. 😬😬😬.

And its working now….

Would be great to delete or edit amateur and public channels…
[Hardware Hacking General] Govillard:
This is mine.
[Hardware Hacking General] Govillard:

I did it, and works…

Only volume position 1 is too loud.
[Hardware Hacking General] Govillard:
Well. I’ve been watching and really, mines is mijia 2

@darkhorse1870, any luck with the compatibility of app with Mijia 2S
[Hardware Hacking General] climberdimo:
Hi, I also ran into hardware version 4.10 and stuck with the update. The software says there is a new version but it shows hardware version 4.10 and after about 15 minutes waiting for an update it says it failed. I guess the only reason is the hardware version. otherwise it is XMDJJ02 version number 1.0.5. This radio also has a huge problem with the output audio level. No matter how much you turn it down between 4 and 1 there's almost no difference and it's still strong. If there is an option to define it in software, it would be great if you could touch it! Thanks in advance to the people involved in this project!

Thank foe your sharing. I had try to use your app and want to asking something. What is the highest frequency after modded? and why in the handheld, the frequency is not change, it is stll inform as before (ex: 440.000).

By the way, anyone know is there the application that can help to scaning instead of scan in Talkie Walkie, it is cannot scan in range just expanded?

[Hardware Hacking General] ggorok:
@darkhorse1870 Just wondering, if I finished the update with modded firmware provided by DarkHorse, what can I expect from the firmware update because I still do not see any difference. Do I still need to update the frequency from the Mi-Walkie-Talkie-Plus? I thought If I updated the firmware, I could set all frequencies from the Mi2 radio device not only from the Mi-Walkie-Talkie-Plus app .
[Hardware Hacking General] Redclaw88:
Is there a way to set the frequencies on the 2s to 446mhz. Apparently the plus app doesn't work with the 2s. Is that still planned? I stupidly bought a 2s without checking the frequency first
[Hardware Hacking General] darkhorse1870:
Thanks to Github user khoanguyen-3fc who dumped XMDJJ02 4.10 firmware and build the "nolimits" mod, updated firmware arhive with hw 4.10 support is available now: https://drive.google.com/file/d/1brgNa3IIF3V7NGUfPz-x62z6DYVVTJpj.

[Hardware Hacking General] tesla2k2:
Thanks a lot for your work so far @darkhorse1870.

Unfortunately I have the same issue as @Redclaw88 - I bought two Xiaomi Walkie Talkie 2S because I really like the design (compared to the "this worked for 20 years, why change it?"-design of all the other available walkie-talkies) but I can't use them in the EU because the range does not support PMR446 (which I didn't even knew about until after I ordered them from China). Sending them back isn't an option because the seller can't even provide an address without typos - they will never make it there.

Any chance you can patch the app so it will connect to the 2S too? I guess, being able to use PMR446 with the custom channels would be enough, soI won't need the firmware mod to change the internal channels. I actually tried it myself but since it's not written in JS or TS I'm kinda lost ;)
[Hardware Hacking General] nazacity:

Hey mate,

Any chance you can push the MJDJJ03FY firmware to your repo here: https://github.com/Mi-Walkie-Talkie-by-Darkhorse/Mi1S-firmware

I'm chasing an unlocked version of the firmware for hardware revision 5.5, figure there shouldn't be too many changes since the one posted here targeted ~5.

Unless someone already has some firmware with the frequency guard removed for hardware 5.5?

[Hardware Hacking General] medic_furry:
If your needs are within the 400-470mHz range, you can try this

400-470 mHz is only software locked, you only need to download the modified version of APK

1/1S/Lite/2/2S （NO 3 Just released, the third-party APK needs to wait )All can be unlocked through software at 400-470mHz,And there is no need to Flash MOD firmware, just install APK

These APKs seem to have been intentionally leaked by the manufacturing company (BEEBES www.ifengyu.com) because software restrictions were imposed to comply with the requirements of the Chinese Ministry of Industry and Information Technology for amateur walkie talkies

The frequency of APK modification does not require specific device models, as long as the product name matches, it can be used. The software supports both Chinese and English

APK China sharing source https://tieba.baidu.com/p/8355311448?pid=147350198014&cid=#147350198014

You need a Baidu account to download. If you don't understand Chinese, I suggest using the Google Drive that I forwarded

google drive https://drive.google.com/drive/folders/1hiiwnlfi2k7Al-UzclJ_KxEQLAKMD0SI?usp=sharing

English can only be displayed when the system language is English, and all other languages will display Chinese, which cannot be modified within the settings

PS

Some people have reported that their 2S can only receive and not transmit at 400-420mHz. I don't have 2S on hand, and Xiaomi store doesn't have a prototype to use, so I can't try whether 2S can work properly on all channels 400-470mHz. You need to try it yourself

"@Ririgege" indicates that unable to connect to he 2S walkie talkie in English mode and and you may need to change the system language to a non-English language to pair it. You might need to use Google Translate for coordination.”

Xiaomi Interphone 3 (not 4G, but UV band analog interphone) has just been released, so it may be several months before the third-party APK file is available. If you don't have Xiaomi SU7, it's meaningless to buy it

Hack Xiaomi Mijia Walkie Talkie

Hi there, I just wondering is it possible to hack xiaomi mijia walkie talkie frequency ? Is connected android phone with MI PTT. Apk to setting and upgrade firmware. I need to unlock freq from 144-148 to global amateur freq 136-174 Rgds JFr

xdaforums.com
[Hardware Hacking General] Ririgege:
Thanks a lot !!! I was waiting for this for almost a year and I can finally use my 2S

I had to use the app in chinese, because I could not find the 2S when in english
[Hardware Hacking General] 355:
I checked. 2S can both receive and transmit at 400-420mHz.
[Hardware Hacking General] medic_furry:
oh! sorry,Can't the APP discover 2S in English mode? After adding, you can switch back to English mode and try again😿

This APK was already available last year, but it seems to have only spread in China, just like the firmware GitHub project of "darkhorse1870" is only popular on xdaforums. I had no idea about it in China until someone told me that there was this project on foreign websites, so I was able to unlock all channels of my Xiaomi walkie 2 talkie
[Hardware Hacking General] medic_furry:
Thx😽
[Hardware Hacking General] llee8820:
This is awesome, thank you for the share!

So if I am understanding this correct…

- I install the apk on my phone and connect to my 2S radio

- I create a custom channel for the frequency I want (for example 462.5625)

- I set the frequency for both TX and RX

- I repeat this for each desired frequency between 400-470 mHz

I saw an option for analog, digital, sub code (closed). Should I leave this at the default setting?
[Hardware Hacking General] medic_furry:
Write the frequency according to your needs
[Hardware Hacking General] medic_furry:
The 4G version of Xiaomi Walkie Talkie 3 has been renamed as Xiaomi Public Network Interphone. Xiaomi Interphone 3 is an interphone with UV frequency😸

It may be because the 409-410Mhz was deleted due to the lack of a Chinese public frequency approval certificate. In addition, the battery was increased, the POGO PIN charging function was added, and the linkage function with the Xiaomi SU7 car was added. The price is the same as that of Xiaomi Walkie-Talkie 2

MI shop China

Xiaomi Walkie Talkie 3 https://www.mi.com/shop/buy/detail?product_id=19764&cfrom=search

Xiaomi Public Network Interphone （4G Netcom device) https://www.mi.com/shop/buy/detail?product_id=15843&cfrom=search

If you are interested, I hope you can update the firmware version of Xiaomi Interphone 3. The process of this machine may be similar to the multi standard wireless SoC of Xiaomi Interphone 2S It is also possible that only the shell has been replaced, because it is more like 2 than 2S

[Hardware Hacking General] jaceyhong:
it is perfectly working at 2s. Thank you.
[Hardware Hacking General] alexeenko:
Thank you! I successfully installed the app and set up 446 frequencies. However, I have another question. The app allows me to set the frequency with four decimal places (e.g., 446.0062), but the PMR standard requires five decimal places - 446.00625. Could someone clarify how to correctly set the legal PMR frequencies for Europe?
[Hardware Hacking General] medic_furry:
Because it will interfere with adjacent frequencies, this operation is not allowed. If you really need this function, you need to change to Xiaomi Walkie-Talkie 2 and use third-party firmware.
[Hardware Hacking General] bela:
Does anyone know if the 2S could be set the Philippine SRRS frequeincies? (325Mhz)
[Hardware Hacking General] medic_furry:
Hardware not supported
[Hardware Hacking General] alexeenko:
Thank you for your response. Could you please clarify which frequencies I can use in PMR446 in Europe? Am I allowed to use any frequency within this range, or should I adhere to the PMR standard? I've configured 446.0062 instead of 446.00625. Everything seems to be working well, but I'm unclear about its legality and whether it could cause issues for others.
[Hardware Hacking General] medic_furry:
I'm not very clear about European radio standards. You can directly set the 4th bit to test whether it can communicate with other European standard radio stations. If not, you need to buy a machine like Xiaomi Walkie-Talkie 2 or Baofeng UV5R.

[Hardware Hacking General] kontek:
Hi I can't find the 2s. How did you change the app to.chinese to find it ?
[Hardware Hacking General] fantomel:
Change your phone language to anything but English and then when you open the mod PTT app it will be in chinese. Pair your 2S with it in chinese and after close the app and change your phone's language back to english. Now open the PTT app again and you will see the 2S there, all in English.
[Hardware Hacking General] R.Fauzan:
Have you unistalled the official mi ptt before installing mi ptt mod?
[Hardware Hacking General] stanleysi:
I never had the MI PTT app installed before. What I did was connect to the walkie via MI home and adding the walkie. I Uninstalled the device from my MI home app and reinstalled the MI ptt+ and still the same. No option to fine tune the frequency because long pressing on the custom channel name header nothing happens... Is it because I'm on the s1 walkie?

Thx all for helping

OK. Hopefully someone can help look at the s1 walkie and help come out with a hack for it. Let me know if anybody needs any more additional information and I'll gladly provide it. Thx!
