Hello,
I purchased my htc mozart 16gb.
But there are some apps that are locked because of my sim card.
The sim card works fine, i can make calls, i just can use these apps.
The apps are written that i can not use are in german language and the Internet Explorer has this as first page:
Code:
http : // www t-mobile-favoriten de/
So, i think my phone is some kind of locked with t-mobile.
How can i fully unlock the phone, if i dont have an unsupported sim?
Thanks.
I am new to Android and NFC and I just can't seem to find a straight answer to this question
If I have an NFC reader/writer device, can I get it to detect my NFC enabled android phone, so that I may be able to transfer data from my phone to the device?
My question on this page,
<< Link in the attachment link1.txt>>
has some links to other discussions about this topic. Most of them hint that this not possible (with the official Android version that comes with the phones), but I have also read that card emulation mode by an NFC device (such as a phone) is based on ISO standards ISO 14443-A and ISO 14443-B, which are endorsed by the NFC Forum.
Moreover, I know that a phone can act as a card writer, so what is the difference between the phone sending out data as a card writer and another NFC reader device reading this data, a phone acting in P2P mode and sending out data and another reader device reading this data AND a phone acting as a card (in card emulation mode perhaps, if it is at all possible) and another reading device reading it? (I am talking about non-rooted android phones only)
So if I have an NFC enabled phone, and USB reader/write, such as, say, this one,
<< Link in the attachment link2.txt>>
can I get it to detect my phone as an NFC device and transfer some data from my phone to the reader/writer?
---EDIT---
Note: I am not talking about getting the phone to work as a secure payment system or getting it to act like some other card or anything like that, my question is more basic: If I want to send out my custom data (say a string "ABC" or some number 1234) from my phone using NFC, can I get an external reader/writer to detect it?
Hello,
I would like to clear all WiFi configurations from an app (programmatically) but not found any solution.
What I tried and it doesn't work.
WifiManager.removeNetwork
I try to use WifiManager.removeNetwork and found that it doesn't work on Android M+
then I try to set WIFI_DEVICE_OWNER_CONFIGS_LOCKDOWN to 0 with the command:
Code:
settings put global wifi_device_owner_configs_lockdown 0
and then try to WifiManager.removeNetwork again but it still doesn't work.
Remove configurations from /data/misc/wifi/wpa_supplicant.conf
Turn off WiFi then modify /data/misc/wifi/wpa_supplicant.conf and re-enable WiFi again. This method work properly on Galaxy S8 but doesn't work on Sony X Performance (my customer's main device)
WifiManager.factoryReset
This method used by Network Settings Reset (in Settings) but it is hidden and requires system privilege.
Use service call wifi <code>
To call WifiManager.factoryReset from a shell, you can use service call wifi <code> however the code depends on the Android version and the Manufacturer modifications. I found that code of factoryReset method is 63 on Android 7.0 and 7.1.1 but it doesn't work on my devices.
Device Owner
found that Device Owner App can make system setting modification, however to make an app as Device Owner requires to remove all account from device. (after make app as device owner, I can use WifiManager.removeNetwork to remove any Aps)

Can you please suggest me other solutions? (ROOT is acceptable but not a system app)
Thank you.
The "service call wifi" is soo much depending on the Android version.
On Android 9 the call for resetting wifi to factory default is:
adb shell service call wifi 59 s16 wlan0
The proper call number can be found in the IWifiManager function. Like for Android 9:
android/android-9.0.0_r35 : android/net/wifi/IWifiManager.java
Count "case TRANSACTION_" from first to last. That gives you the call number. Pretty basic but it works!
To remove stored wifi networks:
cmd netpolicy list wifi-networks #to get list, index 0...
To remove network:
service call wifi 16 i32 1 #remove the second network in the list
(note 3rd doesn't become 2nd after this command!)
No root needed.
Remember this is for Android 9! Other versions may have other call numbers.

I've a problem in my Note 9 device
Not allowing to USE 2 SIM card + SD Card hack
it works fine but an error/blocking message from Samsung "There seems to be something in your SIM card tray slot that doesn't belong there, Check it and try again"
Any solutions ?
Tweaks: bypass MicroSD/Sim2 tray lock
So as most of you know, in latest Oreo firmwares Samsung added a check to prevent using both Sim2/MicroSD at same time in one slot (screenshot in attachments), fortunately this lock is pretty much easy to bypass, do this:
Decompile services.jar, open /com/android/server/StorageManagerService.smali class and in it search for isSimSdBlock() method. It should look like this:
Once you found it, all you have to do is to make sure the method always returns false, so basically all you need to do is to replace the whole method code inside to match this:
Code:
Recompile services.jar, push it on your device, profit
Credits to @corsicanu for the finding, don't forget to credit him if you're gonna use this little tweak on your project
Only solution i found but don't understand what is serviecs.jar where i can find it in my phone
Hi everyone, I am currently at work and we have two Honeywell CT40 devices. We need to somehow get the apk for our stock management app onto one of them. It fails to provision with a cannot find wifi error. Does anyone know how I can pull the data i need from a provisioning qr code?
