Tried Adding Multiple Users and ... phone won't boot up - Galaxy S6 Q&A, Help & Troubleshooting

Just rooted my phone with ODIN/TWRP. One of the reasons was I wanted multiple user support as I'm using this phone as a second phone (no SIM card) that my son can play with, but wanted to have a user account on it as well.
Stupidly, googled this which seemed harmless enough..
[I can't post URL's yet so had to delete this line]
Adjusted the build.prop file as it mentioned, saved it to another directory, and then saved that file over the one in the System directory.
Sure enough, selected "reboot" on my phone, and now it won't power up. If I press power/vol down key it brings up the Galaxy S6 shot, and then just a black screen.
I tried going back into TWRP recovery mode and reflashing Odin, but end up with the same result.
I know, I should have asked here before I messed with the build.prop file, but when the same answer came up on 2 or 3 different public sites indicating how to adjust it to add multi-user support, I stupidly figured it was a simple fix!
Any help getting the phone back would be appreciated! Does Multiple User support even work on this phone!?

Flash stock rom with Odin or just do emergency software recovery from SmartSwitch. When phone try to reboot, force turn off (10 sec press power button) and then enter recovery (vol up+power+home) and wipe data.
This should do it.

Nexus S 4G Bootloop

I do not know where to post this besides here. I have a SPRINT Nexus S 4G phone with stock Ice Cream Sandwhich. Never rooted or touched bootloader or anything of that sort.
After updating to ICS via OTA.. the phone loves to randomly reboot itself whenever it feels like. Annoying but I could live with it. Anyways I take my phone out of my pocket today and it is turned off... annoyed I turn it back on.. google logo.. animated squares... and then stuck at squares...(Bootloader shows locked etc, recovery does nothing)(I have to pull battery to reboot phone... back to squares though) I understand I will lose data if I have to wipe the phone.. but it looks like I am not going to be able to back up any of my phone numbers.. precious pictures or music? I do not have insurance through Sprint.
Whats the next logical step to fixing this?
EDIT: Bootloader information
Product Name - Herring
HW VERSION - REV 34
BOOTLOADER VERSION - D720SPAKE1
BASEBAND VERSION - D720SPALC1
CARRIER INFO - SPA
SERIAL NUMBER - 33324E0247AF00EC
LOCK STATE - LOCKED
EDIT 2: Downloaded all of the files needed to reflash / stock ICS.. I already use PDANET so I don't need phone drivers.. my phone was in debug mode before it crashed. Plug it in.. get to the Triangle information icon..
"fastboot.exe flash boot boot.img"
< waiting for device >
Ideas? Or how do I properly do this by myself? One Click Stock cannot detect my phone
Ok follow this steps
1. Turn off your phone
2. Press and hold volume down and power button at the same time.
3. Youll see an android logo. Now tick your volume down to navigate to recovery select by pressing power button
4 in recovery use volume rockers also to navigate through options and power button also to select.
5. Now select wipe cache. I think stock recovery have wipe dalvik too. So wipe it too.
6. Reboot
If if your phone happens to reboot itself again after doing this steps. Repeat my procedure this time wipe your data you can select this also on stock recovery.and start from scratch. Dont worry your pictures , musics, videos and other stuffs on your sdcard will not be touch. It will just clear all your installed apps.
Sent from my Nexus S®
Ok. I have had the same problem on my Google Nexus S with the boot loop and also the random reboots. This is what I have done to fix this problem.
1. I download an automatic task killer and set it to like every 10 - 20min to clear running apps.
OR
2. Go to your recovery by going into fastboot mode going select recovery. Once in recovery, press the volume down. I hold both up and down and the power button together. You should come up with a menu that says reboot system now, apply update from sd card, wip data factory reset or wipe cache partition. Then navigate to the wipe data menu and select it. Hit yes and there you go. It worked for me. Reply and tell me if it worked for you. FYI, it should reboot by it self, if not just select reboot now and reboot it.

Rooted Droid Maxx won't boot into recovery...

Hey all,
I have a rooted Droid Maxx. When I press Power and Down Volumn I can get into the AP Fastboot Menu. When I choose any of the options Using Vol down to move me through the options including normal Powerup, Recovery, Factory, Barcode, BP Tools it will only do a normal boot. I'm using vol down to choose an option and Vol up to activate the option. I have been able to get into these various options before, but something has gone south on me....any ideas...and what other info do you need?
Also, on the fastboot screen it states:
Device is locked. Status code: 0
EDIT: Strangely enough, when I move to Barcodes and hit the up Vol button, I can get into barcodes...but on any other options, when I press Vol up, it just does a normal phone boot.
the phone has been acting a little twitchy lately...camera won't function and keeps telling me to restart, now e-mail is starting to do funny stuff....Not happy. One of the posts that I read on trying to get the camera working correctly stated that wiping the Dalvic cache might help and I think I need to get into recovery tools to do that.
Thx
Any help anyone? I need to get into the tools to wipe the phone....
Thx

It's not just you apparently. I just tried mine to try to use as a home security camera (after loaning it to a friend to use as a temp phone) and it's doing the same thing yours is, can't factory rest and start over so I guess now I'll have to try to unroot and/or reflash bootloader and get it back to "stock" and try formatting after that.

HTC One A9, Cannot enter Recovery mode.

Greetings all, As the title suggest I have an HTC One A9 unlocked and I am trying to factory reset it after re-locking bootloader. However, Whenever I boot into boot mode and select to reboot into Recovery mode I am greeted with "Failed to boot to recovery mode" With suggestions to press volume up or down to go back into bootmode. Upon resetting my phone I am sent to a data encryption screen where it ask to enter a password to decrypt my data, Now I can enter any number I want and it goes through saying "The password you entered is correct but your data is corrupt." And gives me a button to factory reset my phone, So I press it and it resets my phone and enters bootmode where my only options are; Reboot, Reboot to bootloader, Boot to download mode, reboot to recovery (Which I just covered does not work for me), Power down. I've looked into this problem before coming here and other people with similar problems have no problems entering recovery mode and even have an option to factory reset the phone from the boot loader menu, However I do not have that 'Factory reset' option in my boot loader menu.
I've spent the last two hours looking at various websites and various topics in this forum but cannot find a solution to aid me. I was hoping to be able to just fix this and return to my phones current settings without wiping anything, But at this point I'll be happy to be able to just get past this and will be satisfied with factory wiping the phone and having it be useable, As I'd like to avoid having to buy a new phone it at all possible.
When I go to recovery mode, I get a phone icon with a red symbol in it. Then I'm able to hold power button and tap the vol up button to proceed. If you're fine wiping the phone, have you tried using the .exe rom file from the HTC site? You need HTC sync installed on the PC, and have phone in download mode use it (at least that's what I've had to do). It should, I believe, reflash recovery mode.

[Q] Vizio XR6M Smartcast Tablet Remote - OTA bricked it... help?

This Vizio XR6M came with the M65-D0 display I bought. It was running their unmodified version of whatever software was preinstalled. It worked fine all the way up until they pushed an OTA to it, which is causing it to bootloop. I cannot get into any usable recovery because the screen that appears where recovery options should be is the Android on its back with an exclamation point I believe. Can anyone help me get this thing working again? Thanks.
I was really hoping that someone would have a clue. This really sucks. I'll keep waiting
Had the same thing happen to me. When on the screen with the android on his back, hold the power button and quickly press volume up. This should give a menu with a handful of options. Scroll up and down with volume up and down and press power to select. One of the options is to wipe the device. Do this and then select reboot. (There is also a wipe cache option, but this didn't do anything for me.) This is what I was told to do by Vizio support. Unfortunately I've had to do this wipe 3 times now. This tablet is very unstable in my opinion. (Once after an OTA update, once after I rebooted it, and once it just rebooted itself and got stuck in the loop.) I came across your post while looking for info on rooting the tablet or at least getting a backup like TWRP on it so I don't have to spend an hour downloading apps and getting my settings back like I had them every time the tablet decides to lose its **** and go haywire. Best of luck.
Gah... I spent about an hour trying different key combinations to get into recovery... I thought I tried all the key combinations at that Android screen too... But I guess not. Thanks!! Trying a wipe of cache with no expectations that it'll work... full data wipe incoming....
Getting to the Factory menu
1. Hold pwr button down to turn the tablet off
2. Hold the vol dwn button and press the pwr button
3. Anddroid logo with an ! should appear
4. Hold the pwr button and press the vol up button
5. The factory menu should appear
I just picked up two of these TVs and wall-mounted them and they are pretty fantastic, one of the remotes updated just fine but the other one keeps giving me a signature validation failed when it tries to update. I've wiped the cash down a factory reset from recovery and factory reset from inside Android. Anyone have any ideas? I've downloaded it on 3 different WiFi networks and tried to install it probably 10 times now.
Vizio's online chat support to the rescue. I told them what the issue was, what all I tried, she had me verify that I had already done what they suggest (basically get into recovery and such), and told me to send them a copy of my receipt and I'd get a free brand new one, or they could send me a refurbished one without it.
Here's the instructions she gave me.
Please try the following steps:
1. Power the tablet off. While the tablet is off press and hold the Volume Down and Power keys at the same time.
2. The tablet will vibrate and the V logo screen will pop up. Let go of the POWER and VOL DOWN key when the tablet VIBRATES.
3. The tablet will show a picture of the Android mascot laying on the ground with the text 'No Command'.
4. Press and hold the Power key and tap Volume Up key. (One you've tapped the volume up key you can release the power key).
5. Use the Volume Up and Down keys to navigate the options, and the Power Key as an 'OK' button to select options.
6. Navigate down to Wipe Data/ Factory Reset, and press the Power key.
7. Text will appear in the bottom the screen indicating the tablet is resetting.
8. The Android Recovery options will appear again. Use the Vol Keys to navigate to 'Reboot System Now' and press the power button to confirm.
Note: After the reset it may hang on the V logo screen for 5+ minutes before initiating the rest process.

And after the hair and saliva samples to verify you're really a human and not something from Nibiru, you were able to get into recovery and get it working right?!
Crazy, ive had at least 15 different android devices, and never ever needed to go through a military-style agility course to get into recovery.

It took like 2.5 weeks to get the replacement too, but it was brand new. Now I've got 2 tablets, 3 wireless chargers, and I don't want to use them at all. LOL
Does anyone know if anyone has a factory image that can be flashed? I think mine has bad firmware so resets don't do anything to fix it.
This device have made by Chinese/Indian company Borqs. The code name Bennu-M. Platform is Qualcomm APQ8016 (MSM8916 w/o modem). There should work standard method to bring EDL mode. Hold Vol+ and Vol- at power on (press power). Then connect to the PC. Thus device will stay look dead, however should be detected as Qualcomm QDLoader 9008 on the PC side. This is the factory described method.
You can flash factory firmware from this mode using external bootloader (programmer) for MSM8916 firehose protocol. This procedure is described in the thousands of manuals around the net. Qualcomm tools like QPST or QFIL can be used as good as many 3rd party utils to flash and manage any another available way. Many professional 'box' tools should support this device too but only as 'generic' msm8916 (if applicable).
However I can't find the firmware package for this device anywhere. You should ask and require the manufacturer/distributor to publish firmware, the source code and all the corresponding matherials to be able to flash and rebuild firmware from sources in any manner you want without any limitations as required by GNU/GPL free open source software licenses this firmware is obligated to.
Everyone who have the device working or software dead, can try to dump the current firmware and data, stored on the internal eMMC memory module in part(s) or in whole image using free QTools project utilities and suitable external bootloader with ability to dump eMMC, not only to flash as many factory supplied programmers do. There are programmer(s) for MSM8916 available in the project repo. Read and understand manuals carefully before trying anything!
There is definitely another ways to root, dump, flash, manage the device in any manner YOU WANT, not only the way you are "allowed" to use your own device by manufacturer/distributor. FTA!
You can root the device then dump all the multiple partition images manually (dd if=/dev/block/mmbblk0...... of=/sdcard/......) or using built custom recovery like CWM/TWRP for your device. Please note, kernel sources are important but not mandatory to build e.g. CWM. You can build one using CWM image from the similar device and the kernel (boot/recovery) image binaries from your device. There are good manuals and image repacking utils available around like e.g. AndImgTool.
There are the way to produce factory image from the eMMC/partitions dump(s). Use utils like R-Studio to dump particular partition images from the eMMC dump (it's like whole HDD or UFD image with all the sectors raw, one by one, w/o any modifications/compression/etc) Manuals / utils are avavailable to make e.g. sparse and xml scripts set which is flashable by the programmer in the EDL mode (i.e. from any damaged state, because EDL is built in to the PBL and masked to the internal CPU ROM, thus can not be damaged in any manner, except firing the CPU up).
You can also flash partition images from the more common Fastboot mode, unless eMMC GPT and bootloaders (SBL/RPM/TZ/ABoot) stay intact (logo showed). You can't dump from fastboot, which is common due to the (foolish) 'safety' requirements. It's security by obscurity and is definitely not for your favor, but for the corps control over you and force to send valuable private data to foreign clouds.
Please share eMMC full and/or partitions dumps using reliable 'neverending' file cloud/hosting since there is no factory firmware available yet (ever). I do not own this device and never seen being overseas, so I can't share. Help each other and f... the mfrs and matrix!

Need help with my Google FRP locked [non-rooted] LGL455DL

I made the mistake of Factory Resetting my phone after a few failed attempts at remembering the Pattern to unlock the phone, in doing so I ended up being stuck in the set-up process because I forgot the Google account I was logged into on it before the Factory Reset, had been an account I just quickly made on the spot months ago just to set up an app on it. I'm posting here for help with this since I'm on day 4 of trying to find a way to bypass this and my head is ready to explode. I feel like someone with a fresh mind would be able to point me in the right direction.
If anyone can let me know if I'm doing something wrong or missing some steps that will help me try any one of these, or honestly any advice at all... I'd very much appreciate it and it'd help relieve a huge chunk of this ridiculous headache this has all been.
Thanks in advance!
What I've tried thus far --
- I know for most ways around this, USB debugging needs to be enabled. But since I cannot get past the initial set-up process, I can't access the settings to enable it.
- I also know that for a lot of Android devices USB debugging is enabled by default in Recovery Mode but everywhere I've searched for the hardware combination to boot into Recovery/Download mode, all say the same thing:
Turn phone off > Power up with Vol. Down + Power button until 'Download Mode' is displayed (for boot into Download mode, while holding Vol. Down + Power button plug OTG cable into device)
- My problem with this is that on my device, Vol. Down + Power button, restarts the phone. So instead of 'Download Mode', I'm just restarting the phone over and over again. I was able to get my phone to boot into was Safe mode using the Power button + Side button.
- I've also tried getting around this through a series of steps which involved the 'TalkBack' accessibility feature, but when I try toggling to enable it I just get a message saying "Complete setup first to continue"
From there --
I started looking up Stock ROMs that I'd be able to just flash the firmware. But for the life of me, I cannot seem to find anything for this device. And this is where I'm pretty much at now.
To remove FRP lock you boot into phone's Recovery mode and apply
1. Wipe data
2. Factory Reset
Every Android device gets shipped by default with Android Recovery.

I can't get my device to boot into Recovery mode. Everywhere I look up, it tells me to Power off device, then Press Vol. Down + Power key until the menu appears. But on my device, all that combination does is force the phone to restart.
