ADB does not see my US996 - LG V20 Questions & Answers

I found a very small number of posts about how to get ADB to recognize the V20, but no success. I did just install the latest platform tools.
Any suggestions?

Did you activate developer settings with USB debugging

i see you have decided to root it now LOL! well. first things first. go into developers options and activate debugging. mode. If there is OEM unlock option, also activate that (after all you are going to root, but be aware because it will erase all your data) Also install the proper drivers for your phone on the computer. All these are critical. after that you should be able to detect your device. But just in case, what update of ADB have you downloaded? I used one from the pixel's section on XDA which allowed me to see the prompt box and give permission to my computer to access and make changes to my device.

I thought sure I had turned that on, but it was off. But that was before I had done a software update to 10f. Maybe it changed back. Thanks.

Well, actually, I'm not quite ready to root. But I'll be appreciating your input when it comes time. (I forget...are you on a US996?).
Here's what I am trying to do: I am messing with apps to try to improve battery life while still not rooted. I installed Greenify again, hoping I don't have the same problem you and I discussed over in my Journey thread.
So, I just also installed Forcedoze, which typically 'requires' root. But on first run, it says that if not rooted you can give it the rights to do what it needs to do with the following command:
adb -d shell pm grant com.suyashsrijan.forcedoze android.permission.dump

All being on the same line.
Any idea if that's a bad idea?
[edit]
I just found that I can do a similar command for Greenify and have it do an aggressive doze. I think I'll try that. I may pop back into my Journey thread to update what's going on.

Hmm it wouldnt hurt to try. I mean, without root priviliges there are not changes that can affect the system of the phone internally speaking. So... What adb did you download? I used the one from the pixel because my system wouldnt show me the prompt box asking me whether i want to allow my laptop to make changes to my phone.

I'm getting device unauthorized from ADB. I'm Googling now to find the problem. I am NOT getting stack overflow with it.
[fixed]
Rebooted PC and PHone. When I plugged in a pop-up came up on the phone to authorize debugging mode. That had not happened before. That got it to working.

see? hahaha that's what you needed to find. the prompt asking you to authorize. in my case it didnt show it until i used the adb from pixel's forum since it appear that the adb shown on the rooting method's thread is missing a file which wouldnt allow to work properly so, then after i opened the adb , it did ask me for the authorization box

Trying to root again after 4.2.1 update

I rooted using Mskip's rootkit. I updated with the OTA update thinking I could use the kit to root again. I'm on the latest version of the toolkit after donating and updating it. I go to option 4(root options) then I choose option 1(root). I do this while in fastboot mode. The Nexus 10 reboots, goes to the home screen, and the toolkit says it is "Waiting for Device" Nothing happens. I tried rebooting into fastboot mode again, but nothing. I ran root checker, and it says I do not have root.
Any ideas on what I'm doing wrong.

First off, do you have "USB Debugging" checked in settings? Sounds like ADB isn't working. (Especially since you were already in fastboot mode, which doesn't require debugging.
See THIS thread.
If you have a custom recovery installed, download the superSU app and Su binaries from Chainfire's thread I just linked and flash them in recovery.
If you don't have a custom recovery, use the toolkit to either temp flash or fully flash the right recovery onto your tablet.
Also, if I remember correctly, options 3 & 4 in the toolkit's root menu will essentially do this for you.
NOTE: For future OTA updates, download "OTA Rootkeeper" or "SuperSU Pro" from the market. They both have options to protect root during an OTA update. (SuperSU Pro has never failed me when I used it to protect root when I had my Asus TF700.

Thanks for the answer. I'm not a total newb to rooting things, but defintely not a pro, so some of this goes beyond what I've done before. I'll have to approach slowly. I don't really need root for anything right now, I only rooted to connect BT controllers to the Nexus, and those apps are broken right now anyway.
I do have usb debugging checked. I'm not sure about the other things you asked. I've never flashed anything to my droid devices, so I'll try and go through that thread and see what makes sense.
Thanks!
Well, I tried to run that program from the link, and it said some files were missing, so I stopped it. I tried to flash clockwork mod recovery and when it booted back into Android to rename the files, it got stuck on waiting on ADB. Frustrating.

Yeah, it seems more intimidating than it really is. Luckily, all of the things I listed in my above post are all achievable through the Nexus 10 Toolkit that you have downloaded.
I agree though, take it slow and read through the instructions, that is the best way to avoid breaking something. Rooting is a pretty safe procedure these days, my first Android phone was quite the headache.
When you do decide to root again, you can use the toolkit to either:
-- Install root through ADB (no recovery needed) like you already tried. Beforehand, you should check to make sure you correctly installed the correct drivers.You also need to check the toolkit's "List of attached devices" section to see if you see your device (represented by a string of letters & numbers) whenever your device boots back to the homescreen.
--Or temporarily install the necessary recovery to flash a root package, once it is flashed the device will revert to the stock recovery. (When you see "CWM" the toolkit is referring to a custom recovery BTW.)

Success!
I think the problem coming in for me was not understanding ADB and fastboot. I have the drivers installed, but it wasn't seeing it. I switched to PTP mode and instantly it was being seen in ADB mode by the toolkit. I then ran option 4-->Option 1(Root Device) from fastboot mode. This time when it booted back to the homescreen the toolkit was able to continue with the root and I am now rooted again.
Thanks for taking the time to respond to this and help me out. You mention of the drives is what kind of kicked me in the right direction.

Which root method did you use? The only one I've looked at requires unlock to root. Ive rooted every phone ive owned and they are super easy, they never do a factory reset/unlock to root. BTW I'm on 4.2.1 and i gave up when the toolkit i used wouldnt connect to fastboot.

http://forum.xda-developers.com/showthread.php?t=2001868
I did have to unlock the bootloader so I did lose everything, but it wasn't that hard and I did it early enough that I didn't lose too much of what I had on there.

Urgent help needed. Locked out of phone.

I was poking security options within my phone, and I accidentally locked it with a pattern that I cannot recall.
I tried looking for troubleshooting guides, but unfortunately Marshmallow no longer has a "forgot code?" option. Also, I tried Android Device Manager, but it tells me since my phone already has a lockscreen, I no longer need to add a password (which I intended to do, in order to know said password)
I would greatly appreciate any help, since I really don't want to factory reset, since I got lots of pics I don't want to lose.

Unfortunately, my phone is stock and non rooted, but luckily I could guess the pattern.
I still would like to know for future reference, since Android Device Manager did a great job at getting my phone's location and making it ring... just not unlocking it!!

you don't need to be rooted to access recovery and install files.

He wouldn't have been able to use it because you need a custom recovery to flash that file.
Well... I guess you know the system works? Probably not great for there to be an easy or sure-fire way to unlock a phone if you don't know the security details.
If it's just data you need, recovery mode should allow you to copy it off the device via USB (if you didnt encrypt the device). Getting into a phone you really locked yourself out of is probably not possible.

For preventative measures, Tasker is your friend. Have a "Plan B" microSD with a special .txt file on it, and have Tasker detect SD inserted and scan that file. If the file matches, then Tasker should wipe /data/system/gesture.key and password.key, and sqlite3 into settings.db and "update system set value=0 where name='lock_pattern_autolock' " to unlock your device.
In the case of an aftermath, it is now (as of today) possible to recover files/photos from the lockscreen without root, ADB, or custom recovery. Just an internet connection, linked Google account, and access to the notification drawer. I just published my first app, Locked-out Phone Backup, that is similar to the old Screen Lock Bypass Pro for Gingerbread, but instead recovers files instead of disabling the screen lock, so no root is required!
Hope this answers your question!
Well, try some password remover.

Sony Xperia XA2 - Unlocking

I'd like to start a discussion on unlocking the XA2 bootloader and rooting it. So far, it looks like for Sony devices, you need to send a request through the Sony site here: https://developer.sonymobile.com/unlockbootloader/
But there is no device selection for the XA2. This is where i'm currently stuck at. Does anyone know of any other way to unlock the bootloader?
Okay got it to unlock bootloader.
Steps:
1. Head to https://developer.sonymobile.com/unlockbootloader/. Select Xperia XA1 in the dropdown, follow steps, then get your access code.
2. Pretty much follow the steps in that guide from sony, where you get the access code. The only difference was when installing the fastboot drivers. On win 10, i had to go and follow the steps here to install android drivers: https://android.stackexchange.com/questions/129174/windows-10-fastboot-driver
After that, fastboot was able to recognize the device and unlock the bootloader.
So now, i guess i'm waiting for TWRP to be released for XA2 to get recovery and root.
I've been looking for a XA2 page for a while. Can we request one?
This is a interesting device and I hope the development community shows some interest too.
What's your impressions of it so far?
Agreed, I'm quite shocked there is no development threads as of yet for this newly released device. Already checked mine, and can see that sky mobile have left it unlockable, so I would also be interested in development for this device.

Same. I bought it off Amazon US and I didn't realize I was buying such a recent phone. To any future devs, add "Night Light" feature and swipe fingerprint to bring down notification bar to any ROMS would make this phone a great sucessor to my Honor 8.
XA2 has been perfect for me so far, coming from Nexus 5x. I mostly use my phone for reddit and podcasts, though. Just need my LineageOS on it.

I haven't been able to root yet. I've only unlocked the bootloader, which hasn't caused any problems with bank of America. on my other phone rooting didn't affect bank of America, however Android pay didn't work, and snapchat can only be logged in before root and not after. once you root, you won't be able to log back in snapchat if you logout, however if you log in it'll stay logged in after root.
I've been having problems with the windows 10 fastboot and ADB drivers. i got fastboot to work long enough to unlock the bootloader but then it stopped recognizing my phone. still haven't gotten ADB to work yet ?*

The wait game begins. I'm going to wait to unlock the bootloader until TWRP and root available.
Btw can't you root without changing the recovery using ADB. I don't kno since this my first ever Sony phone.

I think you can sideload with ADB once the bootloader is unlocked. I was under the impression TWRP is like a GUI for ADB. but There's something funky with the windows 10 drivers. it took forever for my phone to get detected in fastboot, and ADB never seemed to work. then, after i unlocked my phone, the PC doesn't even recognize it in fastboot anymore.
likewise, I've always used Samsung phones & odin. This is my first Sony. the lack of root is killing me ?
From what i read, adb sideload requires custom recovery.
Is anyone else on Project FI with this phone? I'm getting awful 4G and wifi performance with the XA2. Constantly losing internet access (even though signal bar is at 5 bars).
Hi guys, I managed to unlock the bootloader but I can not get into recovery mode. I tried with vol- and power button but it does not work . Did it happen to someone? Thank you all

for this, you will need a custom recovery GUI such as TWRP. I believe tht all you can do on this device by pressing volume- is access ADB, and volume+ gets you into fastboot, which can be accessed via command prompt on a PC

Isn't TWRP basically just the GUI of all the ADB commands? I was under the impression you could do almost everything you can do in TWRP in ADB CLI mode on a PC ?*
I was under the impression to sideload you can boot with a USB plugged into your computer and your phone press volume- Then the indicator light in the top right corner turns green, and (if the drivers on my PC would cooperate) then it would accept ADB sideload commands. Now, I am unsure of this; that's just what my basic understanding is. If I could get the damn drivers to work right, I could find out for sure ?

I don't know nearly enough about the android ecosystem to comment, beyond what i found. I think adb sideload is a specific command, which requires twrp. But other adb may work? I don't want to risk it yet anyways.
Regarding drivers, did you try the thing i linked in my first post on this thread? My XA2 is still recognized after bootloader unlock with my method.
What do you know flashtool supports our xa2? that I know no because I tried to convert an ftf file but in the device list the xa2 is not there. also does not recognize me in flashmode despite emma recognize it. thank you

Rooting ZTE Blade A7 Prime

I've used the search function and found nothing for this phone. I've used Google and found nothing about rooting this exact model.
I'm looking for the technique to root this phone and I'm finding nothing. Has anybody rooted and flashed a Custom ROM/custom recovery on this device and how did you do it?
I just got this phone as well, and I have been looking and also have found nothing for this exact variant. I have tried the usual one-click methods to no avail. Is there any development in the works? If you need a test dummy, let me know. I have several other phones to use as spares, so I am not afraid of a soft brick.
Rooting ZTE Blade a7 Prime
I too can be a test dummy to root this phone. Since Visible is such a hands off company you really need your phone to be rooted to do things for yourself. Currently for some reason my ZTE BLADE A7 Prime can’t send or receive calls and their techs are telling me 3 to 5 business days... counting yesterday and today that’s a week! Ridiculous! The APN settings look off compared to my wife’s phone but you can’t edit the settings.
ZTE Blade prime A7 Visible
I've been having the exact same problem with making and receiving calls also with losing service(for the service prob. Found great n easy solution- till find permanent one-**go to airplane mode in settings turn it on for 30secs to a minute then turn airplane mode back off TAKES SIGNAL FROM 0-4 BARS EVERYTIME AND I CAN GET/MAKE CALLS INSTANTLY ETC AGAIN ?)
Data saver seems to work for resetting connection as well. I too would be interested in rooting. I kinda like the phone, but it does have its issues.
First glance at unlocking bootloader
I just received the phone today. I was excited to see that I could get into developer mode and move the OEM Unlocking icon to allow bootloader unlock... Unfortunately, that's where the excitement ended. The typical fastboot oem unlock and fastboot flashing unlock yielded no results. I then did some research and it would seem MediaTek only implements two oem commands, and unlock is not one of them...
"The bootloader may implement additional, manufacturer-specific commands. These do not follow the usual protocol command format, and they cannot have a payload. Some manufacturers implement a lot of OEM commands, as can be seen here. MediaTek just implements two: fastboot oem p2u on and fastboot oem p2u off, these enable or disable the redirection of Linux kernel messages to the UART."
Will tinker with it some more later since I'm limited with time. Hope someone figures out how to unlock the bootloader and go from there.
Has anybody tried this?

I don't own this phone (yet), so I can't give it a shot myself.
I'm not very familiar with mediatek processors in general, but that looks rather promising with some restrictions... If I have time over the weekend, I'll give that a whirl and report back whether it works or bricks my device
seems lke ts gonna be a long process before were able to fiddle with roms but im atleast glad this is close to stock android.
I can confirm that mtk-su R20 downloaded from https://forum.xda-developers.com/hd...xperimental-software-root-hd-8-hd-10-t3904595 gets you root prompt. Use 32-bit binary (arm).
Edit: I can also confirm that the process in https://forum.xda-developers.com/an...atek-armv8-t3922213/post79626434#post79626434 works and root survives the reboots.

Ditto here too. Couldn't get it working at first. Turned out I miss read the instructions and put all files in the init.d folder instead od the two files in the bin folder. Then your tip on using the 32bit binary got it working. Thanks.
Anybody figured out a way to change build.prop to make it stick after reboot? I am trying to enable APN editing by modifying /system/build.prop, but whenever I reboot I lose the changes.
/system and the root filesystem are mounted as a kind of RAM Disk. You would have to modify the actual image files (varies depending on partition scheme) and reflash to make things stick. Now, to my knowledge, doing so would require an unlocked bootloader, which currently is not possible with this phone.

Looks like we can not add an APN even with root then? It's a bummer.

I just received the phone today. I was excited to see that I could get into developer mode and move the OEM Unlocking icon to allow bootloader unlock... Unfortunately, that's where the excitement ended. The typical fastboot oem unlock and fastboot flashing unlock yielded no results. I then did some research and it would seem MediaTek only implements two oem commands, and unlock is not one of them...
"The bootloader may implement additional, manufacturer-specific commands. These do not follow the usual protocol command format, and they cannot have a payload. Some manufacturers implement a lot of OEM commands, as can be seen here. MediaTek just implements two: fastboot oem p2u on and fastboot oem p2u off, these enable or disable the redirection of Linux kernel messages to the UART."
Will tinker with it some more later since I'm limited with time. Hope someone figures out how to unlock the bootloader and go from there.

They removed the fastboot command to unlock the bootloader. I found it out by comparing the similar ZTE Blade 10 and Blade 10 Prime. The Blade 10 non-prime has the unlock command and it works whereas the prime version has the command removed but funnily enough the lock command is still there but is useless. I then looked at the bootloader for the a7 prime and same thing the unlock command is removed from the bootloader. So there isn't much hope for it unless a bypass can be found.

+1 to another confirmation that the above works. Root is available, but there are limitations. I cannot install many of the modules from magisk, but this is still a great start. Thanks for the links :good:
I installed the magisk, however, it seems no root permission when I installed Titanium to remove stock apps, it never get root permission.
I was able to add new APN easily to make it work on AT&T 4G LTE data network. Are you saying any reboot of phone will make the newly added APN disappear?

I was also able to add and APN by just clicking on the "+" icon on the top-right corner of the APN configuration screen. When I inserted by MINT SIM Card (T-Mobile MVNO) there were not default populated APNs, but was able to get everything to work after adding an APN -- even after rebooting.
Big Tip: After entering the APN data and before leaving the data entry screen, make sure that you save the APN or it will not be persisted. Click on the "three dots" menu on the top-right corner and hit the Save menu item.

After studying the process a bit, I've come to conclude that this isn't really permanent root. All this does is the equivalent of running a script to gain temporary root after after reboot. This is done very late in the boot process, if you can even call it a part of the boot process since it's really just a user-space application auto-starting.
The modules are probably trying to be instantiated well before the root is made available through the pseudo "init.d" scripts.
It's still nice to have root access using this technique, but its usability is pretty limited. For example, I can't even get AFWall+ to start up, even if I configure it with a startup delay (hoping that it kicks in after temporary root).
So what are the odds we can make this a permanent root using a firehose file and QPST/QFIL? Similar to the Visible R2 phone?

Bypass lock screen without root or ADB

Got a question that I am not sure has a proper answer (and yes I know this is a sus question to begin with).
I have an old s7 and I forgot the pattern to unlock it. Developer mode is enabled but since I can't get through the lock screen I can't whitelist my PC on the phone when I connect it. I need to access my google authenticator app because I want to export it to my new phone (use to have it on my new phone but for other reasons it got wiped). I've tried using the samsung service mode code to put it into service mode from the emergency call dialer but that doesn't work. Is there anything else I might be able to try?
use droidkit or drfone screen unlock? I think dr.fone has a free trial, maybe you can screen unlock with it. Or just look for any other 3rd party free screen unlocker. They usually don't need root, nor adb.
Ive tried both but both don't support the s7. At this point I would pay for one of these apps to get into this damned thing.
Is it's bootloader unlocked?
Yes you may try with - UFED4PC_7.49.0.2.tar
This is supported to remove or read screenshot without lock data For Android & specially working on many SAMSUNG devices

Is that something you can flash via odin or?
Did some research, looks like a full mobile forensic device suite. I don't have 2000 dollars to drop on trying to open a phone.
NO.
This is a tool which can read your phone lock
I wonder if there is a way to use Odin to flash TWRP for a single boot. It might be enough to push the ADB keyfile to the directory or to delete the sqlite keys for the pattern.

you use fastboot to boot a twrp image on a device, without actually flashing it, but im not entirely sure if you can do it with a locked bootloader. Google it i guess?

I wonder if I could mount the system partition that way or not bootloader aside. Unlocking the bootloader would kill all the data too which is a no-no.
It does seem possible to flash TWRP on some devices without unlocking the bootloader. How would I go about booting from it with fastboot without flashing it if I tried it? edit: nevermind I know how to do it.
I assume I would have to use the herolte img to try to get it to work since there isn't one specifically for the sprint variant.
Well I tried but I can't seem to read the phone with fastboot. I tried Odin and it predictably threw out the flash because it wasn't properly authenticated either.
Did you install the correct drivers? You need the samsung usb drivers for odin, and some adb and fastboot drivers for adb.

Yeah, of course. I have the Samsung drivers and I tried working with linux and had the same issue. Feels like my only recourse at this point is to setup a kali nethunter.
You also need to manually install adb and fastboot drivers for your device, which for me is pain, but maybe it'll be easy for you.

Yeah I have them both. For some reason though Fastboot just doesn't see the device. I tried pinging it with the linux version and its vendor id but it didn't do any good. Kind of a real pain this is becoming. I may just convert my old nexus 11 into a kali nethunter and try to brute force it.
Still haven't found a solution and now I am feeling the consequences. My Nintendo 2FA is on this damned phone. Going to try to call support and get it removed tomorrow but its a real big pain.
Metablaster,
Is there an update to this?
My wife's S8 is pattern locked, she didn't set up a Samsung account prior, and the Google Find my Phone web tool PIN option has been changed/ deleted. Maybe there's an older html version of this somewhere?
ADB keeps coming back that the device access is "unauthorized" even after reboot, so although I thought I enabled USB Debugging before giving her the phone (it used to be mine), she may have restored to factory without enabling it again.
Kali will delete all of the data like a factory reset so that defeats the purpose except to just get use of the phone at all again.
Is there anyone on here that knows of a professional grade service that can do this?
So frustrating...! Why , upon proof of ownership, can't something be done?
Please pm me, I'd want to try the MD-Next option first.
If I run the risk of losing her data than anything more intrusive probably isn't worth it.

MetalBlaster,
I did manage to get the S8 to boot into Recovery Mode, please PM me about trying the MD-Next step via USB bridge.

Have you already tried to unlock the device with a locked SIM?
