Manufacturer blocked unknown sources -Any way around this? - Upgrading, Modifying and Unlocking

Hi all,
Trying to install some apps on a connected car Android system. Apparently the manufacturer (probably intentionally) blocked the "unknown sources" option in settings by removing the OK button of the warning message (see image).
Trying to figure out ideas on how to turn it on. I have no root, no ADB, USB connectivity is limited to host mode only.
I do have access to Play store and developer options.
I'm running out of ideas here.... willing to give a small bounty if it'll help you.

I can't figure out how to enable USB debugging on this ROM. Could someone point me in the right direction ? Also for some reason the app black mart apk won't download. The play store has some apps I want that are only on that app and every time I try to install it I get the
"Not installed" notification. I allowed Google to "time to time monitor unknown apps for malicious activity" or whatever when I first started the ROM. Does that have anything to do with it perhaps?
Figured out blackmart problem. Now for debugging..:thumbup:
I'm guessing it's a 4.2 rom? If so, this is how you do it: How do I enable USB debugging on android 4.2.*? (The “Developer Options” menu item is gone!)
Huh. Weird. :sly:

[Q] CM Version 11-20140113, ADB, Developer options missing. New ROM or where?

With the recent availability of the Android Wear SDK, I thought I should try developing for it, and Android in general. Got some app ideas to try out. So, in short my current ROM does not have the Settings > Developer Options option to get to Enable USB Debuggingso I can connect to my phone via ADB over USB.
My question is two fold.
Assuming I am not blind, and Developer Options really is missing, what am I messing up?
or
Which 4.4.2 build gives me the option for USB debugging and the other developer settings?

Go to the settings..About phone...Build number...Tap it 7 times
Thanks for that! I did not know that was what I was supposed to do. All sorted now.

[Q] Cant install my apk's ... Debugging mode on but getting error message

I have been able to side-load before no problem. used one-drive and es file explorer to download and install apps no problem. Recently though, I am unable to do so. After the last update I guess it turned debugging mode off. I turned it back on and restarted FTV but am still getting an error message that reads something like" cannot install apps from unknown source, go to settings..." or whatever it says. But when I go to settings...debugging mode is on??? Anyone else have trouble?

[Q] Cant access developer options.

Hi,
I have a very strange issue and I am hoping that someone has a solution to this problem.
The tablet SM-T705 came with Build number KOT49H.T705XXU1ANG2 out of the box and it is not upgradeable.
Recently I bought a samsung galaxy tab s t705, The first thing that I wanted to do is root my new toy.
Obviously the first step in the process is to enable USB Debugging but it is a no go !
Here is what I am doing:
Settings > General > About device , Then tap the Build number 7 times.
Once I got the message that the developer mode is now enabled, I go back to the General tab but the "Developer options" are nowhere to be found.
I installed Nova launcher and tried to crate a shortcut for for the "Developer options" but all it does is throw me to the General settings tab in the settings.
I tried to factory reset the device and repeat the process but not luck.
I even tried some apps that are just shortcuts for the Developer options but it didn't help.
Any suggestions ?
I really need root (cant stand all the bloatware).
Thank you for your help !

Your on an old firmware, so that means you'll need to upgrade. Download mode does not need usb debugging. Simply put your device in download mode, flash newer firmware with odin, then root with cfautoroot. USB debugging is only needed to connect to PC while device is on. Hope this helps!
Thank!

This is the latest version based on Samsung's website and I really need to get usb debug going (not only for root).
Thanks for the help.

Rooting the LG Exalt LTE from Verizon (LG VN220) - Request for Advice

TL.DR; Trying to root new Verizon Android flip-phone with Marshmallow 6.0.1, ARMv7. Firmware version: VN22010B. Seems to to be locked down.
Click to expand...
Click to collapse
I'm trying to root the LG Exalt LTE, or LG VN220, from Verizon. Initially, I've attempted the common rooting kits, such as KingoRoot as well as the tools described around XDA. However all failed. I suspect the cause to be the restrictive permissions of /data/local/tmp, which prevents execution of binaries. I believe any kit using this location will likely fail to achieve anything.
As such, I've been looking to achieve the same using manual techniques. The first step, as in most rooting activity is to put the device into USB debugging mode. To do this on the VN220, first compose ##7764726220. When asked for a service code, use 000000 to access a special menu. Select the Developer Options > USB Debugging and select On. There is an additional menu below named Select USB configuration, from which you can select Media Transfer Protocol or RNDIS among other options.
With that done, you can verify that you can now communicate with the device via ADB. To do so, download the Minimal ADB and Fastboot bundle. While I was successful in querying the device with ADB with
Code:
adb devices
Trying to use fastboot simply outputs "< waiting for device >" indefinitively. It is also possible to open a shell using ADB, however attempting ADB with root will fail. I don't think this is caused by having wrong drivers, as all the other tools could detect the phone (see below), but rather a permission issue.
From there, I've try to boot in different modes, which are accessible by turning off the phone, and then powering up the device while holding the Volume Down button. This will boot into a white screen with some options, including the "Safe Mode" option which I attempted. The second mode is the "Firmware Upgrade" mode which is accessible by again, powering down the phone and powering it up again, but this time holding the Volume Up for 3 seconds.
Attempting to run the following fails:
Code:
fastboot oem unlock
That being said, I later found out that LG does provides a legitimate way to unlock the bootloader via their LG developer portal. Unfortunately the VN220 is not in the list of supported devices, nor does the procedure given applies to this phone. Additionally, it requires the device ID which fails also since it requires fastboot:
Code:
fastboot oem device-id
The other attempt I've tried is using the LG Mobile Support Too l and while it was useful to obtain the KDZ file from their website, it also failed to apply the update. LGUP didn't recognise the model. (Note that both requires the USB mode to be RNDIS to detect the phone)
Trying to run apps from the internal storage such as su or even using the chmod command only results in "Operation not permitted" messages. So even temporary root seems rather difficult.
At this point, I'd like to know if anyone has any advice on additional things I could try to root the phone, or even have temporary root.
Thanks in advance
@cyberrecce
Why?
First of all thank you, I've been looking for that service code to enable developer settings / adb since I discovered the phone secretly runs Android. But I don't see why we would need root, I've been using adb to side load apps since I can't get to a menu that allows it

1. Why? To install a custom ROM.
2. Did you get any issue with certificates when side-loading apps? I keep getting INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES. Can't seem to find the "Install from Unknown Sources" option.
Same problem

re: the certificate error for side loading apps...
Code:
adb shell settings put secure install_non_market_apps 1
turns off the unknown source block, but I'm still getting INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES
Could the apk itself I'm trying to use have a bad certificate? Or is there another solution?

Just curious - any success or updates. I can't seem to get past " INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES"
For installing apps I'm still not getting past INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES
I even tried pulling an apk from my LG G4 that successfully installed on that device and tried installing it on the Exalt, but same error.
The biggest reason I've seen for the INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES is apks that are signed poorly. When I check the apks I'm using for their signatures with the JDK it says one or more of their signatures lack a timestamp which can cause problems.
Also, downloading the apk from the Exalt's browser and trying to install from either
settings > phone settings > storage > phone > explore > downloads > open > install
or
tools > file manager > internal storage > downloads > open > install
has been coming up with "app not installed" after it tries to install the apk.
I'm not really giving up though, I just don't really know where to go from here.

Can you please share with us the KDZ file?

You will need to:
- unlock it’s Bootloader. If the “fastboot oem unlock” command will not work (and I’m quite sure it will not, since we’re talking about a USA LG device), you can stop here and throw the phone out the window.
- if by some any miracle you will be able to unlock the bootloader, you have two ways of rooting it:
1. Using TWRP and a superuser zip file (magisk or the now Chinese owned supersu). The main problem with this is that you will need to compile TWRP yourself, since I doubt anyone will bother for such an obscure device.
2. Using a prerooted boot image. You will need the stock boot image, install the latest magisk manager, let it root it and then flash it via fastboot. This is particularly difficult because you will need to decrypt the kdz file (if any available) in order to get the boot.img
Even if by a greater miracle you will be able to get 1 or 2 working, there still is a huge chance that the fastboot flash command will be disabled.
Forget about solutions like king/kingoroot. Best case scenario they will fail. Worst case scenario they will softbrick the phone by gaining temporary root and then modifying /system. That will in turn trigger dm-verity which will cause the soft brick.
Forget about the scams like oneclickroot. Their so called techs will try the aforementioned and fail and you will waste your $40.
Sorry To deliver the bad news, but there’s no way out of it.
Thanks for taking your time, to help me.
I will check if I can unlock the bootloader.
Thanks alot

Any sage advice on the [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES] issue when sideloading apps?
 @jfn0802 said they had success with sideloading, but haven't been online in ages, and none of the rest of us seem to have had the same success. Minimum, that's what I would like to accomplish.
[side note, has anyone switched from Verizon with this phone? I'm looking to, but I'm wondering a couple of things like, does verizon have the mobile hotspot function restricted from use on other carriers? & etc & just wondering how it's doing off-verizon for anyone.]

Isn't that what turning on the "install from unknown sources" option should do? I still get the Install Parse Failed after switching it on with ADB.
@98jbsz I've tried to uninstall without success. What way did you do it? And does it just leave a blank space in the menu screen?
[Less on topic, sorry again, but has anyone seen the LG Wine LTE? http://www.lg.com/us/cell-phones/lg-UN220-lg-wine
It's strikingly similar to our friend the Exalt LTE here, but it seems less carrier branded/available at US Cellular, so I'm wondering if that would make a difference?
Major differences Wine LTE has more 4G bands (2/4/5/12/25) versus Exalt (4/5/13), which kind of has me kicking myself, because travel and 4G was one of the reasons I bought the Exalt. Both have quadband GSM and WCDMA, but interestingly the Wine also has CDMA.
Beyond that, there are some more smaller differences I scavenged from their LG pages, Exalt has more bluetooth profiles, supports more music formats, has more GPS capabilities, wifi calling, and 1 more ringtone. Wine has more supported video formats, and an FM radio.
I'm curious about what/if the Wine would have for sms messaging (I doubt it'd have Verizon's message+) and instead of my Verizon app...]

Alright, I also managed to uninstall my verizon and verizon's cloud app using
Code:
adb shell and the pm uninstall -k --user 0
But the Verizon apps folder on the menu screen remains, although it's empty. Any ideas on how to remove it?
Then I tried to install an apk using
Code:
pm install
and it came back with [INSTALL_FAILED_INVALID_URI] which...is a different than [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES], but not better.
right, but when you first copy the APK to the phone, and then you install it, you will see the [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES] error. still not a solution
