[Completed] [Q] How to remove twrp and fully unroot LG G3 d-855? - XDA Assist

I have rooted my LG G3 and tried flashing twrp (no idea if it worked, when booting to recovery the notification led just flashes red and blue...). I decided that I want my phone to be completely stock again (If thats possible..) and couldn't find info on this for G3 devices. I'm quite sure that my twrp flash attempt failed but I would like to remove any files that the installer might have placed on my phone when attempting to install it. I also need help in unrooting my device, I have heard that you can do so from SuperSU, but does that FULLY unroot my device? I am running Lollipop 5.0

Hello and thank you for using XDA Assist.
This thread here http://forum.xda-developers.com/showthread.php?t=2785089 should provide the information required to completely flash your device back to stock.
This is the only way to actually reset the device and completely remove any files you may have uploaded to the device while rooting and attempting to flash custom recovery.
This method will also wipe all internal storage. So please back up anything like picture, videos and files you would like to save.
Also make sure you select the appropriate firmware for your device.
If things are unclear I suggest you ask the individuals in that thread as those are the users who are experts in your device.
Good Luck!

Install Android 4.4 beta 3 on LG L5

Hi, guys I'm new to android phones...but I'd love to know more about them and about these custom roms...so the point is that I read this thread http://forum.xda-developers.com/showthread.php?t=2519448 and I don't know how to start ... I have a LG L5 E610 and the default ROM is a little slow...I need to mention that my phone isn't rooted...is brand new...so pls can you help me...I searched the Internet but I founded so many things and I'm kind of mix up...
Go to this subforum for your phone and read up on what's needed.
http://forum.xda-developers.com/optimus-l3-l5-l7
The procedure varies slightly from phone to phone but you first need to unlock your bootloader (the first unlock will wipe any data you have stored on the phone, make sure you backup first)
And most importantly don't be afraid to ask as many questions as you need, we were all noobs once
Also, once you got a custom recovery installed, make sure you do a full backup before experimenting, that way you always can get back to a working device no matter what happens.
Good luck and enjoy.

[Completed] [Q] Moto X 4.4.2 rooted w/ locked bootloader, factory reset safe?

Hi, I have a republic wireless moto x I just successfully rooted and updated to 4.4.2 from 4.2.2 with a locked bootloader with no write protection (wp)
Since I updated it to 4.4.2 I have this error that pops up that I can not resolve
"Unfortunately, the process com.motorola.process.system has stopped"
I googled several pages of several website results and several pages of google but can not find the solution.
Solutions found was to:
Safe Mode (I tried this first with no apps installed on non safemode and non system apps updated, didn't work and popped up even on safe mode)
Change date & time method (didn't work)
Wipe Cache (didn't work)
Wipe Cache & dalvik cache (didn't work)
I am debating about factory reset but unsure if it will make me lose my root because I have a locked bootloader (if that matters in anyway I am still new to this, and that my moto x is from republic wireless not like other carriers with unlocked bootloaders).
Please help me and discuss with me how I can get rid of that error. Or point me to the right path.
Do you have a Custom Recovery Installed ? If not, then that would be your first Step. There's a Moto X Link in my signature that will help you install one. Once that is done, you can do factory reset from inside the Recovery. But before you boot, make sure to flash SuperUser Zip File from the Recovery.

Hello. Not sure how to answer this because I am still new to it.
I have the SafeStrap App, it says "State: Installed" above Install Recovery / Uninstall Recovery & "Safe System: Not Active" over Reboot to Recovery" version 3.65.
I do have a SafeStrap (TWRP) and have a backup but not sure if it is on 4.2.2 or 4.4.2.
If I did a recovery, which parts will it back up or all of it? Because I don't want that error to show up. It is driving me nuts.
Can you further assist me with what I replied before I do that recovery?
I see that you have already Opened another Thread on the Moto X forum.

[Completed] Galaxy S5 Active (SM-G870A) stuck in bootloop!

I don't really know why my phone is stuck in a bootloop to begin with. I've tried EVERYTHING I could possibly think of!
Here's What I've tried :
WipeData/Factory Reset and I also wiped Cache.
I tried to use ODIN to flash the original stock ROM to the device but the bootloader is locked so its impossible to flash any ROM to the devices (Even if it's official).
I tried to apply the Lollipop 5.0 update in recovery using a external SD card.
I tried using ADB sideload.
(Bonus points if you can give me away to unlock the bootloader! because i'll know what to do if it's unlocked.)
So...If anyone has suggestions, I'll happily take any!
Also Please! Leave links so I have quick access!

rooted bricked boost mobile moto G. 4.4.4. i messed up my phone while editing "build.prob" with es root file i believe and when i was done editing i clicked on the folder looking icon on the top right corner which i thought was enter/save but itwas something else that rearranged the letters after it booted i only got bootloader unlocked warning screen and a plain black screen after and thats it however i can also get to the the fastboot menu. so any way can i get my phone back with maybe just using adb and fastboot. i just rooted my phone like a week ago so never got to play around with it so i have alot to catch up with on terms and research dont worry i'll look up what you tell me to do rather than keep on asking how how and how. well guys hope you can help me thank you.

Hello, and thank you for using XDA Assist!
Quite possibly my easiest problem of the night.
Your bootloader is unlocked. So....flash custom recovery. One that can do adb as well (unless you Moto G also has an SD card slot, but if we are talking about the original 2013 model, then one won't be there).
Then, reboot into recovery. Make a backup. Pull the backup files to your PC (either by adb or MicroSD, if available). Extract the system backup file (is a tarball) in a Linux filesystem. Fix up your build.prop mistakes. Tar system back up, and bundle the backup as a second set to push back to your device. Restore that backup (need only be system partition). Profit.
Any further questions, can ask in the following thread (assuming you have the 2013/1st gen non-LTE version - otherwise reply here with variant details for further instructions):

No problem.
USB debugging being off is only a consequence if planning to ADB in from system. Recovery has it's own rules.
Not sure about the "cannot unarchive" message, but if you can get the stock ROM, that's a viable option as well.

and if it helps i tried using stock recovery with this method (installed. 4.4):

and adb works when im on custom recovery if that helps out

Hello,
Fastboot is unable to flash zips unfortunately. That's the recoveries job.
If you can find fastboot images of stock, you can flash back that way.
Especially at this point, I would urge you to take advantage of the help thread I mentioned earlier. They know more about your device (particularly what's available and what not) they I would.
Hope this helps!

Need Guru to Discuss Rooting in general with me

I'm fed up with people on this forum. I keep trying to engage people in a discussion, a conversation to explain some things to me and No one seems willing. It's like there are No Rooting gurus that can answer my simple questions. On a forum full of Android developers, I'm very disappointed, I thought i'd get tons of help. If you read this, Please consider staying to have a discussion/conversation with me.
Preface to The Discussion:
I have used both Android and Linux in the past, I know what Super User is, I use it in Zorin 12 Linux and own a rooted (kingroot) android tablet. I am trying to get information on rooting my Figo Atrium phone by trying to understand Rooting better in general. perhaps this discussion will make since to you and together you can help me find a way to root my phone - But I Must have a back and forth or I'll never understand this. - I know there are many exploits to root a phone used by tools like kingroot. I know these exploits are many and varied depending on your phone's CPU architecture, and software and not all root tools with work with my device. . I know the bootloader has to be unlocked and one must have USB Debugging enabled in Developer Options. I know some phone manufacturers make tools that help you root your phone (MTK Droid Tools) So far, none of these tools can root my phone.
Let's Start The Discussion Here:
I was able to not root but my Upgrade my phone from Lollipop to Marshmallow. I did this using SP Flash Tool and these instructions (which were badly translated and which as you can see by the comments in the video, I had to correct due to bad translation) See this video and comments by me to understand. https://www.youtube.com/watch?v=EEIJM2YjNzE - I used SP Flash Tool and a Rom Figo provided. After I figured out the botched instructions, I was able to upgrade my device with no problems.
Question 1: Isn't this essentially the same process that is used for Rooting? It proves my bootloader is unlocked and the phone does have the ability to flash a new Rom. <- Based on That, doesn't it seem to you that my phone would be in fact Rootable?
If you think so, tell me why, if you think Not, tell me why.
Question 2: If you think So, then: Someone suggested to me that using a tool like Magisk or SuperSU may be able to root my device. Does this seem likely to you based on what I've told you so far? No one in the SuperSU sub forum can answer this question.
If you think No, then we'll discuss this more. I'll wait for your replies. Thank you.
Rooting is, simply said, placing a 'su' binary in the system folder. SU means switch user, when you give that command you're instructing Android to give you root user privileage. OEM's don't want that to happen so they won't include it in their ROMs. Tools like supersu are made to copy that 'su' file to the system partition. There are a lot of ways to explain this, I'm just giving you something quick and easy to understand.
Now regarding your questions;
1) Flashing anything requires the bootloader to be unlocked on most phones. BUT MTK phones don't. (Except some HTC phones). SP Flash Tool can flash any partition without needing to unlock. It's dangerous security wise, but this means its also easier to root.
Infact all MTK phones are rootable. So don't worry about that.
2) How to root? The best way to root is with supersu. (You can also try magisk if you want to use Android Pay).
You need a custom recovery like TWRP first.
I found one here which is for your same CPU. https://www.needrom.com/download/twrp-recovery-13/
^I am just giving you a link to recovery which uses the same CPU so It may or may not work. PLEASE take a backup of your original recovery before doing anything.
Now download SuperSU zip file from here https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.82-201705271822.zip
Don't open it, just keep it in your sd card.
Flash the recovery using SP Flash Tool (check only the recovery box and select this file). Now unplug the phone and press Volume Up+Power Button to boot into recovery.
Then if it says swipe to allow modifications, swipe.
Now goto Install->Select the Supersu.zip file you downloaded->Swipe and reboot.
That's it! You're rooted!
Thanks.. again, you've answered things others couldn't. Much appreciated.
You say, " You need a custom recovery like TWRP first.
I found one here which is for your same CPU. https://www.needrom.com/download/twrp-recovery-13/
^I am just giving you a link to recovery which uses the same CPU so It may or may not work. PLEASE take a backup of your original recovery before doing anything."
Lets say Twrp doesn't work. What is this for, just to re-flash your original rom in case twrp fails at making a backup? ( I assume the tool makes your installed rom flashable in case the root doesn't work and you need to revert back to your original system) I have the SP Tool and the Rom for Marshmallow that works with my device from Figo. Can I use that if Twrp fails - or am I not understanding what twrp is used for? Just checking before I start this. Otherwise, I'll try to follow your instructions to the letter and see what happens.
Still Looking ?
STILL Looking? IF so, a few thoughts .... It is a nice phone for the price. The newer version eventually coming out looks even nicer, and for now, it is still my backup phone to my Figo Gravity. Discovered Figos when I got totally fed up with BLU phones.
ONE - If you have upgraded your Atrium to Marshmallow, as I did, none of the rooting methods that worked on Lollipop will work, so forget about them.
TWO - Down in Developer Settings you need to make sure OEM unlocking is allowed.
THREE - ASSUMING you have a TWRP build that will work, it is pretty simple. Take the ROM image that FIGO sent you and replace the "recovery.img" file with the TWRP (re-name it recovery.img and save the old one as recovery.old JUST IN CASE) file. It will be much larger than the factory ROM recovery image and that's fine. The scatter table, if you read hex addresses, provides for enough space to do this. Flash ONLY the recovery (TWRP) image, and be sure to DOWNLOAD ONLY with the SP FLASH tool. If uncertain, DO NOT PROCEED. It can be a real pain in the arse to re-do things if you accidentally format or upgrade things you didn't mean to. ASSUMING that worked, you can boot into TWRP by holding down the power / volume buttons (I assume you are familiar with this sequence).
FOUR - it is entirely possible that the next time you boot the thing normally, TWRP will be blown away. Happened to me a few times. There is some setting down in the boot image that causes this and I will have to dig up my notes to see exactly what the heck it was. It required taking apart the boot image - I used Carliv - fixing the one setting, and then re-packing and re-flashing it, BUT, you can ALWAYS keep replacing the TWRP image as needed. Inconvenient, but better than a sharp stick in the eye.
FIVE - when booted into TWRP, you should be able to flash SU, which will give you root, and it should STAY rooted after that unless and until you uninstall SU. FLASHIFY is STRONGLY recommended as a VERY useful app for rooted devices. TWRP, if you are unfamiliar with it, is SO MUCH MORE than just a recovery replacement. Handiest whole device backup there is. Has saved my bacon on several devices through numerous acts of personal stupidity. :crying:
SIX - IF ALL ELSE FAILS, you can ALWAYS revert to the factory image ROM. Just DOWNLOAD ONLY rather than Upgrade and DO NOT Format.
