Today, I decided to delete bloatware that came with the tablet that I thought was unnecessary. After doing this, the tablet's settings app would crash. So, I decided to do a factory reset from lg's stock recovery. Doing this, caused the tablet to boot and then keep saying settings has crashed allowing me to go nowhere (Not even to the launcher). So, I am stuck with a tablet that is unrooted, has no recovery, and also isn't recognized by LG's support tool. Is there anything I can do? Thanks.
Put it in download mode (I believe with the tablet off, hold the up volume button then press and hold both it and the power button), download the 24A KDZ I have a thread here for, and flash it with the unofficial LG Tool 2014, then re-root with Stump (it may be myth but I've had better luck with Stump with USB Debugging turned on, then reboot first), then follow the special instructions to get TWRP installed. Always do a nandroid backup before debloating, and factory reset never puts things back in system that you took out, just erases data (settings and apps), cache and Dalvik.

NOTE: This device is not mine, it belongs to my girlfriend and I am the one troubleshooting for her.
here goes:
Yesterday, while a friend of my girlfriend's was playing with her Galaxy Nexus (my GF's), it suddenly rebooted itself without warning.
From what I understand, Nexus bootloops that are caused by faulty flashing usually loops at the "Google" logo (correct me if I'm wrong). Her's is a different story, her Galaxy Nexus is pure stock, locked bootloader, un-rooted and definitely nothing custom on in; literally pure stock. Instead of looping at the "Google" logo, her GNexus loops at the "X" logo, my assumption is that there is something, maybe a rogue app, that is causing her device to bootloop upon reaching startup phase.
I know this isn't a software/ROM level issue since we were able to get to her lockscreen a few times and then the phone reboots after a few seconds. I've tried wiping cache but didn't work, and she won't let me try wipe data/factory reset because she has a lot of important files on her phone. So odin flashing and wipe data/factory reset is out of the question.
so here are some details that might be of interest:
1.) Her phone is not rooted and is pure stock android 4.1.2
2.) does not have custom recovery
3.) does not have usb debugging enabled (not sure, but I assume it's not enabled)
4.) can still boot to fastboot/recovery/download mode
5.) reboots at the X logo
So the basic troubleshooting methods are out, now I'm thinking of using adb pull to extract files from her phone via adb, but problem is, usb debugging is off! Is there any way of recovering her files at least without booting to the ROM itself so I can flash another version of android on it (via odin)?
I've also read about "safe mode" that boots the device without starting up 3rd party apps, only the core essentials. I'd like to go down that route if possible, but we've tried most of the guides on how to boot into safe mode but to no avail. There was one time though that the device booted up and she managed to: open power menu > hold power off > reboot to safe mode, but nothing happened, it just rebooted only to get stuck at the X again.
I may be overthinking this, so I've turned to XDA for help. I know you guys don't like people asking n00bish queries but I've exhausted everything I can think of and I'd like to try everything before I go down the route where I can possibly do even more damage.
I really need help with this, anyone have any ideas? We'd really appreciate it!
Unlock, flash custom recovery, wipe system, data, cache, dalvik cache and flash 4.3 factory image. Problem solved.
I have the V500 on CM12.1 unofficial. Everything was fine and then I went to do a backup in TWRP. Then I looked at the restore menu but didn't do anything. I backed up to my SD Card. Then I booted back into the system, but all that came on was the back button and the notification tray and status bar. The background was black. No home button or multitask button. So I reset it a few times. Eventually I could get into the tablet but when I clicked on a app nothing opened. I then reset it again and it kept coming on with that partial screen. I tried to boot into recovery to try and restore the backup but ADB was locked and the button combination didn't work. So I decided to flash back to stock using LG Mobile Tools. Eventually I could get into download mode but when it got close to finishing to flash the software it stopped and gave me an error. After doing some hard reboots it eventually flashed the software because it would boot into the LG screen. But it was stuck in a bootloop and I've read that in order to fix that you need to do a factory reset. So I tried to boot to recovery but when I pressed and held down volume down and power nothing would happen. Sometimes it would flash the LG logo for a split second. Eventually after a lucky try the LG logo stayed on and I could boot to recovery and do a factory reset. Then everything was back to stock. But when I turn off the tablet it won't power back on unless I plug in the tablet. Battery is fine. Regular battery life it just won't turn on when I power it down without being on the charging screen.
Hello,
I've had my SM-700 (Live Demo unit) for the last few months. Pretty much as soon as I got it I ditched the SamWiz and installed a few different custom ROMs to get most of the system. This all went fine, but, unfortunately, the ROMs always had a problem reading battery life, would cause the device to get really hot, and die. especially if watching videos or gaming. Literally 100% to 5% in 15 minutes. I'd then restart it back up and the see the battery reading was actually around 80%. Really annoying obviously.
So today I decided to go back to Samsung, try their own firmware again, maybe I'd like it?
So I downloaded the UK 5.0.2 firmware from sammobile and flashed it using Odin. So far so good, but when I try flashing TWRP... nothing. I hold down power, vol + and home and I see an android guy lying on his back for a moment with the words "no command" and then the basic Android System Recovery screen. (reboot system, wipe/data/factory reset, wipe cache partition... etc) and when I tyr and select factory reset I'm not allowed. because "MDM does not allow factory reset" and it boots back into Android again.
Please help, I'd love to at least remove some of the bloat that comes with this thing and install a few extra apps non-play store apps of my own.
FYI: Using Odin 3.09 and downloading from here https://twrp.me/devices/samsunggalaxytabs84.html
I've tried versions 2.8.6.0 and 2.8.7.0 of TWRP. Same results.

MDM - Manufacturer Demo Mode.
Flash TWRP again, disable auto-reboot in Odin.
Reboot in to recovery immediately after flashing.
Hold POWER +HOME +VOL DOWN then as soon as the screen goes blank immediately change to VOL UP whilst still holding the other buttons.
Factory reset in TWRP.

Thank you! That worked!
I'm not entirely sure if this is where I should post this, but I am having a problem with my Fire Phone and I really hope you guys can help.
So, story time. I was thinking that I wanted to install a new ROM on my phone just to try some new things. I decided on the SlimKat android 4.4.x ROM and I installed it with GAPPS using SafeStrap 4.01. However, the new ROM was not working correctly so I thought I installed it wrong. So, I read up a little bit more on this and it said that I had to do a factory restore beforehand so I did it with high hopes that it would work. However, it sill did not work. What happens is that I power it on, it asks whether I want to go into SafeStrap or not, it continues if I say no, and they it starts with SlimKat. After about 20 seconds, it stops the starting animation and starts its boot loop.
Since I factory restore it, I had no back ups or and ROMs that I could install on my device. I try to plug it into my computer but it is unrecognizable even if it is the recovery. I also tried going into download mode, doing it multiple ways, but with not luck. It still goes into the boot loop. I factory reset it multiple times but still with no luck. Within SafeStrap, I tried to wipe it, but it is unable to wipe the Dalvik Cache or Data. If there is any way that I can move the stock ROM onto my phone, it would solve all my problems. If any of you have any ideas, please let me know.
I having same problem. Unable to go to recovery mode in normal way, but I could managed to go to recovery by attaching it to computer with usb cable and keeping pressing power + Vol up key for few seconds.
Then I tried Factory restore, Adb Sideload original file downloaded from amazon, but the problem still not solved.
My phone is keep flashing amazon logo in loop.
If any one have idea please help.
Long story short installed substratum and it was working fine, had a navbar theme already running and installed another one. Few hours later rebooted phone and when it booted back up systemui crashed and it went into bootlooping into that over and over again. Now it bootloops a few times and goes into a recovery menu that only gives me the options to try rebooting again or a factory data reset.
The phone boots into bootloader/fastboot just fine and I can get into recovery but the only options I have are 'try again' and 'factory data reset' I know that FDR is basically my only option and so be it. BUT IF POSSIBLE I want to try and backup the internal data or at least as much of it as possible.
So, is it possible to backup any internal data with only having access to bootloader/fastboot.
I've spent over an hour searching to this answer but either I was searching wrong or simply was not able to find the answer. Pixel XL is 100% stock. Never modded, never rooted, stock recovery, stock latest official Oreo from OTA update.
So again. Absolutely no access to the OS. Only access bootloader/fastboot and a form of the recovery menu and I would like to somehow backup the internal data. I don't care about apps or any app data, specifically just the user data if at all possible. If not well then I'm screwed and that's that.
Hello,
Happened to me also something like this. The phone rebooted and the only option were those presented to you also. But, I pressed the "Try again". If this still doesn't work, when the device is rebooting, and the white screen appears, try and hold on to the power button until the moving dots appear.
Also, this didn't wipe anything on my device.
Hope this is useful to you.

Does nothing. Just reboots back into recovery. I've tried Try Again probably 100 times and nothing ever changes. Even safe mode does not work. The SystemUI is completely dead.
I'm 90% sure there is no way to fix the phone other than factory data reset and I'm fine with that. I just want to know if I can backup anything from bootloader/fastboot before I do that.
Have you tried using ADB to boot ( not flash ) a custom recovery, and from there to backup the phone, and after if it's possible, to use the USB-OTG to copy that backup to an USB memory stick?
Looking at the Substratum FAQ in the app it says that if you experience a bootloop you should be able to flash /storage/emulated/0/substratum/SubstratumRescue.zip in recovery and it should fix the boot loop.

As Matt already mentioned, there's a rescue zip file which comes by default with substratum. It's purpose is to remove all overlays which you've currently installed.
In case you don't have a custom recovery installed you can simply boot into twrp via adb (without having flash the recovery)

What if you're bootloader locked? Is there a way to recover from a bad overlay?
You could try to flash the factory image if you've unlocked the BL, just remove the -w from the flash all script

If you have checked the option to potentially allow unlocking your bootloader in dev-settings you can use fastboot to unlock your bootloader and boot into the bootable recovery image
