Can't access recovery on T-Mobile phone. - LG V20 Questions & Answers

I was trying to wipe my cache through the recovery screen, but for some reason T-Mobile has blocked access to it . Only option that pops up is factory reset. Is there any way around this without root?

Connect to computer and use adb

I'll have to try that can't believe T-Mobile would tinker with this.

[Q] Rooted mytouch 3g wipe?

Okay so I had my myTouch rooted, and the only problem I have so far is that it keeps restarting on its own. I called up the guy who rooted it, and he told me that I needed to wipe my phone to see if that might work. He also told me that a factory reset won't work, and said something about taking out the battery? How do I wipe my phone without harming the root?
Through a custom recovery is the only way I know. Although I'm sure you can do it with terminal or via adb from your computer. Try Googling it.

Rooted and encrypted phone. How do I unencrypt?

I have a Nexus 4 and I'm running the stock ROM, but I am rooted. I encrypted my phone and have tried a factory rest in recovery and in the settings on the phone. It simply restarts and it's still encrypted. In recovery I'm using CM and it errors stating it can't load a file. What is going on and how do I make my phone work?
I'm trying to run Nexus Root Tookit v1.6.2 and it also still encrypted.
Is their any way to hard reset this phone? I tried fixing permissions in CM and it still won't let me wipe and do a factory reset
What do mean by "encrypted", do you mean you re-locked the bootloader ?

Your name is "mobileboost", you are new, and you are trying to figure out to hack and encrypted phone?
Hmmmm smells a bit fishy...

Can someone tell me what he means by encrypted.

No known way to decrypt. If you want to decrypt you'll need to erase the user data partition in recovery. Which will wipe any user information.
If that fails you'll need to flash back to the stock using the methods in the android development.

There is a encryption option in security section, requires a pin you created to decrypt every time you power on the phone.

I can confirm ibegary's statement. When you encrypt your phone it warns you that the ONLY way to decrypt it is to wipe all data from your SD card.

How can you erase all data?
Factory reset doesn't work. It reboots, but all is still there.
What can I do?
To connect to my company I had to encrypt data. But I want to start over.
I have no problem to erase all, but I don't have an idea how to do it.
Now days a lot of companies have a BYOD (Bring your own device) policy that requires users to install Google Apps Device Policy from the play store. This then enables you to get in to your company emails and what not. You have to complete a set of procedures, encrypting the device is one of them. You also need to have a decrypytion PIN that allows you to use the device. Furthermore, your companies admins can access your device remotely.
I tried it on my backup Nexus S and when I wanted to go back to stock, I had to uninstall Google Apps Device Policy first. Then I did a factory reset. Of course, you need your PIN to begin.

I came across this (just now) and discovered the only way to do a factory reset was to flash the original stock recovery and do a factory reset from there. You can flash the factory recovery using the toolkit.

I have a Nexus 4 My BYOD policy made me encrypt my phone, and I have my phone rooted running stock.
A simple factory reset worked for me.
Everything I have read said it shouldn't but it did. I am running android 4.3
Maybe an update fixed this issue.

[Q] Stuck on AT&T logo

Hi,
I am stuck on AT&T logo on my Galaxy S4. I had previously installed safetrap recovery and a ROM on it, but I am always using Stock ROM. I forgot about safetrap last night when I had to encrypt and use my device for work related stuffs. So, I factory reset my phone, I encrypt the device and after that I am stuck on AT&T logo. Safetrap still shows up during booting but I can't create any ROM slot, I believe it is because of encryption. Can someone please help me?
Your not on MF3, are you...
How long do you wait on the att screen? If you factory reset it. Sometimes it takes a long time on the att logo and it should boot up back to factory. But if it deleted important files you'll have to take it to best buy to get it fixed or run the new mj6 via odin but safestrap will be on it until you manually remove it via adb or terminal emulator.

[Q] XDA is my last ray of Hope for my locked Nexus 4

Hi,
My wife just replaced pattern on Nexus 4 running android 5.0.1 with PIN Code yesterday night. In morning, she just doesn't remembers it (Girls are Girls ) Wi-Fi, Bluetooth and mobile data connection settings are turned off.
Phone has Android Device Manager installed and activated as well. But unless it doesn't have a working internet connection, its of no use. Lots of pictures, very precious
It was never rooted. USB Debugging is enabled and its bootloader is unlocked(i did it during kitkat update).
1 Is there any way through which i can recover the data?
2 Maybe i can root it in some way or install any custom recovery through which i can take backup/copy the data?
3 Is there any way to get this phone connected to internet i.e. reverse tethering or anything?
4 Can i flash the previous or same factory image so that i can get into the system and access the data?
Please help guys, XDA is my last hope of ray !!
Even if it is locked, you are able to turn on/off mobile data or WiFi. Just slide the statusbar down.
If the bootloader is unlocked you can install a custom recovery, twrp, with fastboot. Then use adb while booted into the custom recovery and pull the data you want off the device.

Is adb pull working with stock recovery?

No, you need a custom recovery
Edit, I keep forgetting that twrp has the ability to enable mtp. So it's as easy as booting into recovery, enable mtp, then just copy and paste files from you device to your pc. No need for adb pull commands.

Phone not booting up

So I set up my phone with all my apps, and turned it off and now it won't boot up. Any idea on how to get it to work?
Sent from my Nexus 6 using Tapatalk
When you say it won't boot, does it not turn on at all? Does it hang on boot? Bootloop?
Guessing you've checked the obvious like charging the battery, trying another plug, etc. The phone shipped with a USB type C charger with a C to C cable, as well as shorter USB A to USB C cable to use with a standard USB charger. I'd try both of them in different wall plugs and the USB A cable in multiple charging blocks.
Can you enter bootloader mode by holding POWER and VOLUME DOWN?
Sorry for not being detailed ?but yes it is stuck in a bootloop in the initial Google screen. It also let's me get into the bootloader by pressing power and vol down. I've tried the factory reset option and still the same thing.

Did you try going into recovery and wiping cache and dalvik cache?
I would suggest flashing factory images, but I am not sure if you will be able to unlock the bootloader if you didn't enable it in developer options. I have read that trying to unlock the bootloader might not work if you didn't enable the option before attempting. Might also cause issues, but if you're already unable to boot, I don't know that it would necessarily be worse.
Google will likely suggest flashing the factory image before an RMA could be initiated. Hopefully someone more experienced than me can confirm if you must enable OEM unlocking before attempting. Unlocking bootloader does wipe data, but this shouldn't be an issue if you already tried a factory reset.
If your bootloader is already unlocked and you modified anything, I would bet a factory image flash would fix it.

The phone is actually not rooted so when I get in to the bootloader it doesn't give me the option to do any of that. This is really weird not sure what caused this to happen ?

Follow step 9 to get your phone working again. That is if you are unlocked.
But don't relock your phone again, go back and read each step and follow it correctly.
Things that cause bootloops:
Not flashing the chainfire's modified boot.img
Using TWRP to install root when you exit it. If your phone is not rooted it will ask you to install root upon leaving TWRP and always say no. SuperSU and root are flashed with a file in TWRP, the file can be found linked in the tutorial I linked above.
Thank you all for the help, I got the phone up and running
