[Q] US Cellular Galaxy SIII (SCH-R530U) on T-Mobile network

I ordered a Samsung Galaxy SIII (US-Cellular) on ebay and tried to follow the instructions below:
1. Type *#197328640# and it brings up the factory service menu
2. Select (1) UMTS
3. Select (1)Debug Screen
4. Select (8) Phone Control
5. Select (6)Network lock
6. Inside the Network lock menu, Pick option (3) Perso SHA256 off, Passed that is a screen that says something like "no options in this menu, current command is 11863", Wait for 30-60 secs, from there hit the menu button on bottom left of phone to bring up options, Select "Back".
7. The last command should have brought you back into the Network Lock menu, at the bottom is (4) NW Lock NV Data Initialize, Select it. You might be asked a saftey are you sure, some people not, after it begins that process wait a good 60 sec the reboot. Thats it! Phones Unlocked
Somehow the phone is not reacting on the USSD 'secret' codes. I can push the hash-button, but nothing happens. I found on a forum that I should root my phone. So I did through Odin. But superSU keeps crashing and I get the error: Security Notice, an attempt to access a secure area...
I don't really need a rooted phone, would be nice, but I would like to use USSD codes, like *#06# for example.

R530 is CDMA based and might not function correctly on TMo.
Also, USSD codes only work on TW-Based ROMs or stock. Root should have no bearing.

What you are trying to do is unlock the phone from US Cellular to use on T-Mo. If that's the case, you will have to downgrade the firmware to Android version 4.1.1. This does not require Rooting. You will see appropriate firmware on SamMobile.com. Try the same process after the downgrade.
Don't try the downgrade if you are on android 4.3. It will Hard Brick your phone.

Tasker profile to change input to Swiftkey on reboot

Hi,
I use SwiftKey ($) as my standard keyboard on the S3 since the built in keyboard mostly stinks. But the one problem is the input method reverts to the Samsung keyboard when the device reboots. I searched around & couldn't find exactly what I was after, so thought I'd post my solution here to pay it forward. :angel:
Requirements:
Rooted phone (using SuperSU free)
Tasker ($)
Secure Settings (free)
Busybox (free)
Process:
0. before starting, install Secure Settings, go to system+ tab, click to enable. It will help you get busybox if not installed. Once installed, again go to system+ tab and get it Enabled.
1. create a tasker "Event" profile
2. Event type is System>Device Boot. There are no options here, tap to go back
3. New task, give it a name ("Change Input Method" is good)
4. + to create an action, then Task>Wait. I put 40 seconds here. This is the delay after reboot before tasker goes & changes the method. It takes a while for my phone to be ready to roll after a reboot. YMMV. Tap top left to go back.
5. Now + to add another action and select plugin
6. Secure Settings, pencil to modify configuration
7. System+ Actions>Input Method, tap to select the input method (Swiftkey for me but this could be anything you want).
8. Click the save icon.
That's it. Try rebooting and see if the input method is changed to Swiftkey after the reboot. Works for me! Enjoy! :laugh:

Moto E4 Guide To Fix Freedom Mobile Stuck On 3G

This guide is similar to my Moto G5 Plus guide, but is a bit more complicated due to not having a signed image with the correct EFS items.
WARNING: These tools can easily brick your phone, use this entirely at your own risk. Only advanced users should attempt this.
Requirements
Moto E4 Qualcomm version (tested on Verizon XT1767, but should work on all)
QXDM software (specifically, EFS Explorer) and basic knowledge of how to use it
Steps
Ensure you have a working QXDM setup, you can follow this tutorial step 1, then from step 4 until step 9 only
Insert Freedom SIM, boot up phone and ensure it can connect properly
Shut down phone. Hold the volume up and down buttons at the same time while pressing power
Press volume down button until you get to the "BP TOOLS" item, tap the power button once on it
After the phone boots up, start up EFS Explorer from the QXDM suite, connect to the phone (it will show up as "MSM8917" under QPST Configuration). You can do this by selecting the phone from the QPST Configuration screen and going to the "Start Clients" menu item and choosing "EFS Explorer." Choose the same port on the next screen, leaving SPC code as is, and press OK. Refer to the linked tutorial above.
Navigate to nv -> item_files -> wcdma -> rrc. In this folder, right click in the file list on the right hand side, select "Copy Item File from PC" and select each of the files in the attached zip (wcdma_rrc_fast_return_to_lte_after_csfb_timer, wcdma_rrc_fast_return_to_lte_after_csfb, and rrc_b66_plmn_support) and press ok (do this one by one). Ensure "Overwrite Allowed" is selected.
Go to the phone menu -> reset phone. Then reboot your phone.
Proof
Note: If you remove the SIM card you may have to do this over again.

I have implemented this fix and it works great.
Just some tips to save others some time.
1. You do not need USB debugging/Developer options on or the Motorola USB drivers installed.
2. The archive in the linked QXDM/QPST tutorial is no longer available but someone reposted in the last few pages of that thread.
https://forum.xda-developers.com/showpost.php?p=73160851&postcount=1187
3. If using Windows 10 you must boot your phone into BP Tools mode before you connect to the PC. After connecting the phone under Device Manager you must go to View > Show hidden devices to see the Moto E4 appear 4 times under Other devices.
4. You must force install the HTC driver that came with the archive I talked about in step 2. However to do this you must disable signed driver enforcement in Windows 10. Unfortunately I could not disable this with the command line option so you have to do the following:
Click the Start Start menu and select Settings.
Click Update and Security.
Click on Recovery.
Click Restart now under Advanced Startup.
Click Troubleshoot.
Click Advanced options.
Click Startup Settings.
Click on Restart.
On the Startup Settings screen press 7 or F7 to disable driver signature enforcement.
5. Once Windows 10 boots up connect the phone that booted in BP Tools mode. Once you are in the Device Manager > Other devices you will update the driver of the 2nd instance of Moto E4 in the list of 4.
6. After installing the HTC driver you should see the HTC Modem appear under Modems in Device manager. Right click > Properties and get the COM port of the HTC modem to use with QPST.
Hope this helps someone.

LG G Pad X 10.1 FRP (Factory Reset Protection)

I just got one of these from a friend of mine who did a factory reset on it before he gave it to me, and now it asks me to login to a previously used account. Unfortunately, he's terrible at remembering his login information, and he doesn't remember his password for the account he had on this anymore. He doesn't need it because he bought an IPad and doesn't use his google account anymore. So now it's stuck on the login screen. I've looked around and I couldn't find a way to bypass the FRP that I felt I could trust, or that seemed to apply to my device. I was wondering if anyone knew how I could do this?

Well, I didn't figure out how to get rid of the reset protection. But, I did get into the settings and was able to set up and use a guest account.
First get a SD card with an apk on it. I downloaded one from apkpure. Then when the device asks you to connect to a wireless network, check the Show advanced options box. Then in the Proxy settings drop down box, select Manual. And click on the Proxy hostname box to bring up the keyboard, and press the settings button on the keyboard that looks like a gear. From the keyboard settings menu you can click the mulit-window button on the bottom taskbar and can open two windows. Open the file manager in one of the windows. In the file manager click on your SD card and try to install the apk you put on it. When it prompts you that you need to allow Unknown sources in the settings, click on the settings button to open the settings window. (Do not check the allow Unknown sources box, if you check it, and the device resets or runs out of battery you'll have to go through this again, but when you click on the apk it won't prompt you to go to settings to allow unknown sources because they're already allowed.) Now just click on Users and switch to guest. There are some limitations to this mode, like not being able modify the wifi network (you'll have to switch back to the Owner account to change this).
I don't know if there's any way from the guest account to reset the account lock, but at least it's something.

I tried this and got as far as to the part where you said to "click the mulit-window button on the bottom taskbar."
That multi-window button is greyed out for me so I cannot click on it. LG must of patched it up or I am doing something incorrect.
Any other advise will be greatly appreciated!

It's possible it was patched out. They've been fixing little exploits with patches. This is the only way I was able to get any access to the device. All I can really recommend is to try everything. Check every menu, every option, and see if there is opening you can find to get access to the device.

Try this
I found a FRP bypass workaround if you are running 5.1.1 on a LG G Pad X 10.1 V930 AT&T model, not sure if all models are the same. It was FRP locked and all of the other bypass methods must have been patched. I was at the setup screen after a factory reset. I hope this helps.
1. Connect to wifi, then go back to start screen
2. Go to Accessibility > Vision > Enable Talkback
3. Go through the talkback training then draw an L to bring up the quick settings select Text to speech Settings (bottom right corner), afterwards you can disable Talkback by holding the power button and holding 2 fingers on the screen until it disables.
4. You will be in the settings app. Go to Users > Add user > User > Add user > Set up
5. You will be brought to a User setup screen select Next > It will pop up the wifi connection screen select next > You will be asked to sign into a Google account, sign into your Google account and proceed with the Google setup.
6. You will be brought to the homescreen. Go to settings > Users > And sign in as Owner.
7. Go to Settings > Factory data reset > Reset tablet. You can now factory reset and you will not be prompted to sign into a Google account.
