[Hardware Hacking General] Guantenk:
Hi Mortalink, It seems to be abnormal. Mine works just fine using Darkhorse1870 miptt+ and the mod firmware. Still be able to edit frequencies via the walkie talkie. Im using the MJDJJ02FY.
[Hardware Hacking General] catcraft:
My MJDJJ02FY shows the same problem. I was on Firmware 1.0.5 before I started to look for a modded firmware. Upgrading to the latest mod from Darkhorse1870 was successful, but I cannot change the frequencies via device menu.

Additional info: miptt+ shows Hardware Version 4.2

Can anyone help? I like that device, but want to use it 'almost' legaly...

thanks for your help guys.

regards,

catcraft
[Hardware Hacking General] Guantenk:
Sorry, to clarify. When using Darkhorse mod miptt+ and mod firmware, Custom channel is still editable directly via the walkie talkie BUT it is editable only within the original default freq range.

My hardware version also v.4.2.

I guess only [MENTION=3834168]darkhorse1870[/MENTION] can fix that.

Lets just hope he is still in the mood :)
[Hardware Hacking General] thanh_giong:
I've realized that when we load the the hacked firmware, the gen2 doesn't work well out of designed band 430MHz-440MHz. I tested with my friend at 430.1375Mhz both TX and RX were working well. When we tested at the frequency of 462.575MHz, TX was working well, xiaomi sent good signal to a baofeng but I received nothing from baofeng. I'm not sure if there is any limitation of the hardware or not, I hope [MENTION=3834168]darkhorse1870[/MENTION] will spend sometime to fix it. TIA

PS: I forgot to mention, the TX was work badly when the distance is long, we tested the distance is about 6km. TX/RX both works well on the short distance.
[Hardware Hacking General] artadita:
thanks bro, from the very beginning the modification was very steady and helpful, for additional I want to ask if the amateur channel frequency can be replaced or edited
[Hardware Hacking General] Xin_t0:
is it possible to add missing ctcss? 69.3 for example.
[Hardware Hacking General] DGin3010:
I did upgrade my 1s firmware with ptt+, everything run well, but when k try with 462,625 to my baofeng 888, baofeng cant receive it, but my 1s can receive the frequency very well. Anyone having the same problem?
[Hardware Hacking General] Xin_t0:
M1s only have 38 ctcss not 50. Channel 1's baofeng 888s use 69.3 hz which m1s doesn't have it. Just like what i asked erlier.

Sorry for poor English.
[Hardware Hacking General] DGin3010:
Everything work very fine, previously i didnt set up the sub-code, once i set up the sub-code both 1s and baofeng 888 can receive and transmit very well.
[Hardware Hacking General] alittlemisfit:
the default xiaomi 1s mhz range is 400-440mhz. can it really works for me to match baofengs 477.225mhz?
[Hardware Hacking General] kokopoe:

My Xiaomi Mijia Gen2 Firmware is 1.05

Hi there Darkhorse,

I some help. BTW thank's a lot for the update on MiPTT+.

I have some trouble on my firmware. My unit is updated on 1.05 version, it's newer than your mod (1.04), so it can't be downgrade to your mod version.

could you just help me? maybe any tips to downgrade my firmware or something.

Because, I have tried to restore to factory default, but it can't change my firmware.

Thank's a lot in advance for any help

regards

---------- Post added at 06:38 AM ---------- Previous post was at 06:33 AM ----------

I have same problem here, my unit has already use firmware 1.05, and the darkhorse's mod is at 1.04. So it can't be downgrade.

I think our problem were only could solved when darkhorse create a new MOD, at least on 1.05.

will wait for it
[Hardware Hacking General] Ciplenok:
Dear darkhorse1870, thanks a lot for very long, big and good work. My walkie talkie 2 working perfect on VHF frequency.

[Hardware Hacking General] Hihihehe159:
firmware 1.0.5

Oh I have the same problem. My device has been updated to firmware 1.0.5 and I have no way to update your mod 1.0.4. Hope you can continue to handle this problem. Thanks
[Hardware Hacking General] Hihihehe159:
I figured out how to fix this. Because we do not carefully read the instruction manual "Mi PTT +". Please read section 4 carefully

4. Added the ability to install modified firmware.

Now you can use Mi PTT app mod to flash custom firmware to all supported Xiaomi Mijia Walkie-Talkie radios. To do so, you should create the folder named "Mi-walkie-talkie.firmware" in your phone's internal memory, and put the correctly named firmware file(s) there. While such a folder exists, "Mi PTT+" believes that connected radio has firmware version "0.0.1", so the app will try to perform a firmware update. In case if there are any firmware files suitable for your radio model and revision in "Mi-walkie-talkie.firmware" folder, such a file will be flashed to the radio; otherwise, the latest official firmware version for your radio will be used (so you can revert to the official firmware by creating the empty "Mi-walkie-talkie.firmware" folder).

Please, do not forget to remove or rename "Mi-walkie-talkie.firmware" folder upon the firmware update - otherwise, "Mi PTT+" continue to treat your radio firmware as version "0.0.1", and will not operate correctly.
[Hardware Hacking General] damn66:
so how to fix?
[Hardware Hacking General] Hihihehe159:
Transceiver error

After finding out how to change the FW mod. My radio seems to be doing very well. However I found out that. There is no problem with broadcast. But receiving the signal, my Xiaomi Gen2 radio is not good. It can only receive signals within 10-20m. I lost contact with the icom radios at a distance of 30 meters but he could still hear me. I just didn't hear anything from him. We use 164.500Mhz frequency. We hope you will review and check
[Hardware Hacking General] erkamahendra:

[Hardware Hacking General] erkamahendra:
Dude...at least could you just give your video a subtitle in english?

I'm tottaly lost in translation...
[Hardware Hacking General] Hihihehe159:
PTT + mod always considers radio the V0.01 version no matter which version of your radio is. It doesn't care if the radio is in V1.0.5 or V1.0.n +. As long as it connects to the radio and detects that there is an updated version in your phone, it will immediately show the radio update status. Let's find out about that with PTT +. You need to follow these instructions:

Step 1: Extract the Fw mod file.

Step 2: After extracting, you will find a file named "Mi-walkie-talkie.firmware"

Step 3: Copy the folder "Mi-walkie-talkie.firmware" to the phone memory. (Note: the phone memory is the external memory where the system folders are located.) Here PTT + will scan and detect the folder "Mi-walkie-talkie.firmware", it will understand that an update is available new.

Step 4: Go back to PTT + you will see the "Flash" button pop up and you just need to click.

Step 5: After updating, you must delete the folder "Mi-walkie-talkie.firmware". Because if you leave that directory in place, PTT + will always think that an updated version is available

It appears Darkhorse1870 vanished a year ago. The video mentioned above does NOT help those who have gen.2 Mi Walkies with 1.05 on them. Ver 1.04 is needed - and I don't know if a rollback or workaround is possible. If I find something, I'll put it here. #
[Hardware Hacking General] darkhorse1870:
I've updated my MI PTT+ mod to 2.13.7 version. Now, mod should be fully compatible with updated Mi Walkie Talkie 2 model XMDJJ02 and with Mi Walkie Talkie Lite XMDJJL01. Original post updated, download the new mod version here : https://xdaforums.com/showpost.php?p=78533983&postcount=30

An important notice about using MI PTT+ on Android 11 and newer devices

To use MI PTT+ custom firmware flashing feature on Android 11+ devices, you should manually give the storage access permission to MI PTT+ application. To do this, long-click MI PTT+ icon, then click "App info" --> "Permissions" --> "Storage" and check "Allow management of all files" mark.

Attention!

The app mod itself does not extend the walkie-talkie frequency range; you'll also need the modified radio firmware!

Modified Xiaomi Mi2 (MJDJJ02FY) and updated Mi2 (XMDJJ02) firmware v.1.0.5 is available here: https://drive.google.com/file/d/1brgNa3IIF3V7NGUfPz-x62z6DYVVTJpj. This mod allows to use an entire walkie-talkie radio chip frequency range 130-520MHz for the user channels, without any redundant software limitations (the actual frequency range, though, is limited by the radio circuitry and could vary from one radio to another).

To install the modified firmware:

1. Unpack "Mi2-nolimits-20220408.zip" file to your phone's internal memory. As a result, you should get "Mi-walkie-talkie.firmware" folder there with firmware files for MJDJJ02FY and XMDJJ02 inside.

2. Run "Mi PTT+"; connect to Mi2 radio; proceed to "Radio Settings" --> "Firmware Update" and press "Flash 'shark_1.0.5-mod-nlt_hwX.bin'" button to start firmware update!

3. After finishing the update, close "Mi PTT+" , remove (or rename) "Mi-walkie-talkie.firmware" folder, and reboot the phone (or you can force stop "Mi PTT+" if it is easier for you, it will be enougth). That's all!

Remember - firmware update is a dangerous operation! I am not responsible for damaging of your hardware; do it at your own risk!

Add the modified firmware for Xiaomi Mi2 model XMDJJ02 hardware revision 4.9; archive link updated.

[Sony Xperia XZs Questions & Answers] cb0gus:
I got this Sony Xperia XZs (G8232, device: keyaki platform: tone) that came pre-installed with Android 8.0 and finally decided to build and install an AOSP image. After activating the OEM unlock under Developer Options I was able to execute the following commands:

$ fastboot -i 0x0fce oem unlock 0x....
$ fastboot flash boot out/target/product/keyaki/boot.img
$ fastboot flash recovery out/target/product/keyaki/recovery.img
$ fastboot flash system out/target/product/keyaki/system.img
$ fastboot flash userdata out/target/product/keyaki/userdata.img

Note: Sony recommends to use the platform tools version "26.0.2 or older" and that's the version I used.

All these commands came back fine but upon boot the device is stuck at the "Sony" screen early on. To make matters worse I'm unable to get it into fastboot mode to debug.

Holding Power and Volume-Up brings the dreaded "Your device has been unlocked and can't be trusted" screen and boots into the "Sony" screen after 5 seconds where it's stuck.

Holding Power and Volume-Down does nothing. Sometimes it will just boot into the "Sony" screen where it's stuck.

Holding Power and Volume-Up while an USB cable is connected to my computer appears to make an attempt to boot into fastboot mode as the LED is coming on blue but then goes out again. Running "fastboot devices" in a loop while it's doing that brings up nothing.

I connected the phone to a Windows PC and had both Emma and the Sony Xperia Companion installed. Emma appears to have found something on "USB 1" but can't do anything with it. The Xperia Companion is unable to find the device and proposed to run a recovery routine. And then this routine appears to have found the device but aborts early on with "Device has been unlocked" and refuses to continue:

Boot loader unlocked
Xperia Companion cannot update this device since the boot loader has been unlocked. Please go to
Developer World to get more information on how to restore the device to standard Sony software.
UEGetPhoneInfoRootedDevice
UE_2003
2.1.12.0 / Windows 10 32 bit / Win32 / US

But since I cannot use fastboot to re-lock the device I'm kinda stuck here. Pun intended :-\

Any ideas how to continue?

Update: Holding Power and Volume-Down does get me into the Android Recovery menu where I can Reboot/Reboot to bootloader/Apply update from ADB/..." and now fastboot is able to find the phone - but I'm unable to re-lock the bootloader:

$ fastboot flashing lock_bootloader
...
FAILED (remote: unknown command)
finished. total time: 0.020s

The same goes for "oem relock" or "oem lock" or "flashing lock_critical". And I think locking the boot loader will be necessary for the Xperia Phone Companion to eventually recover the device.
[Sony Xperia XZs Questions & Answers] jeoleo7:
You are missing the vendor in the log.

I see you did not flash the vendor image.

Download the Vendor image for your version, extract it and flash the image inside.

fastboot flash oem <matching vendor version>.img

https://developer.sony.com/develop/open-devices/downloads/software-binaries

Else try this way to get the stock:

Hold (power and volume +) till it vibrates 3 times.

Install Flashtool.

Download some stock FTF using Xperifirm or any other download links.

Make Flashtool ready to flash the phone now it prompts to connect.

Now holding the vol - button, plug it in; Flashtool starts flashing and its done.

Hope it helps.
[Sony Xperia XZs Questions & Answers] cb0gus:
[MENTION=5271437]jeoleo7[/MENTION] yes, you're right. In fact, I was trying to get rid of the Sony bloat that came preinstalled and skipped the vendor binaries in attempt to omit those. As I now re-gained control via fastboot I was able to:

fastboot flash oem ~/SW_binaries_for_Xperia_Android_8.1.6.4_r1_v15_tone.img

...and with that the device now boot. But all is very unstable and the Settings app is crashing as soon as I try to open the (already enabled) developer options. I'll try to get Flashtool working here (doesn't seem to work under Linux and I only have a 32-bit Windows installation at hand, but Flashtool for Windows is 64 bit only) and will report back. Thanks!
[Sony Xperia XZs Questions & Answers] jeoleo7:
You may try an older version of Flashtool that supports 32bit!! :cool:
[Sony Xperia XZs Questions & Answers] cb0gus:
Thanks, [MENTION=5271437]jeoleo7[/MENTION]. Yes, I did that and installed v0.9.18.6 but then I could not get the phone into Flashmode. While Fastboot, for Flashmode it instructs me to

Unplug the device

Power off the device

Press the back button (I assume the Volume-down button is meant by this)

Plug the USB cable

....and I did all this but the prompt just sits there and it's not doing anything. In the console log window I see this:

09/041/2018 15:41:37 - ERROR - root : this bundle is not valid
09/041/2018 15:41:37 - INFO - Selected Bundle for Sony Xperia XZs (G8232). FW release : 41.3.A.2.171. Customization : Customized US
09/041/2018 15:41:37 - INFO - Preparing files for flashing

...maybe the newer version of Flashtool helps, but then I'd need a 64-bit Windows installation first.

Anyway, disregarding all this - all I really want is to re-lock the bootloader so that this Sony Xperia Companion tool can magically fix the phone again. Is there really no way to re-lock the bootloader with some simple fastboot command?
