So, I was just casually browsing the web on my pc, when I needed to do something on my phone. So I pick up my phone just to find it boot looping with no chance of entering recovery, only fast boot. I haven't unlocked it. I haven't installed TWRP anything. Please help meee .
If you are able to boot your phone in fastboot mode, and does not have any important data on it, you can try a factory reset from fastboot. To do it, install adb and fastboot with drivers in your pc, go to dastboot mode on your phone, connect your phone with the pc, wait for drivers to be installed, and type in cmd:
fastboot erase data
fastboot erase cache
And then, try to reboot the phone by typing:
fastboot reboot
First boot after that can be long, so wait up to 10 minutes. If it will successfully boot, you will have to pass the configuration wizard and install your apps again.
Very important
If your phone is connected with Mi account, you have to remember your password for this account. It is because MIUI has an built-in anti-thief protection like iPhones, and it will be triggered. So, you will not be able to activate and use your phone without Mi account password.

Is there any chance to get my files back?
Hopefuly yes, if it was backed up in Google Drive or Mi Cloud.
Or there is a possibility that you will be able to transfer your files into your pc if you plug in the phone while it is bootlooping. Hopefuly the PC will see your phone and thw files on it, or if you used an adb before, and granted an authority to your pc, you can use an adb to cppy your files.
If above options does not help, the only way is gping to the service care and asking if they can fix the phone without losing your data.
Unlucky, you have a locker bootloader, so you can't install TWRP and have an ability to easy copy your files into your pc.

Alright here is my situation. I ran the latest OTA update on the stock rom and the phone started going into
a boot loop. My problem is that I havent performed a recent backup and need to access some files on the
phone. Developer mode is enabled, however I disabled USB debugging prior to running the update. When my
phone reboots, I remove the battery and restart the phone but every once in a while my phone successfully
loads and I am able to punch in my pin to unlock the phone. However, a few seconds later the phone reboots.
I tried to access the phone using ADB but because I dont have USB debugging enabled I dont see any devices
when I run the "adb devices" command. I also tried to acquire a smartphone image using encase forensic, but
yet again, because USB debuggin is not enabled, I am not able to pull data.
I am able to go into recovery mode and I tried to wipe my cache partition, but that did not help.
My questions are:
1. Is there a way for me to access my data files while the phone is stuck in a boot loop and USB debugging is
disabled?
2. Is it possible for me to download the latest update, copy it over to my sdcard and rerun the update from
my sdcard from recovery mode? Could this possibly solve my problem?
3. In a worst case scenario, if I do a factory wipe/reset, will this solve my problem and what is the
likelyhood of recovering my files from the data partition?
Any tips, tricks, advice is greatly appreciated.

Thanks svs57 for the quick reply.
Would you mind elaborating a bit more? I am an IT guy but by no means a developer. When I boot into recovery is the phone supposed to show up in My Computer via MTP or PTP? The phone is not showing up as a device. Or am I supposed to use adb commands to pull the files down?
When I go into recovery and run the "adb devices" command now I get what appears to be a serial number followed by the word "unauthorized". I rebooted and went into recovery mode again this time tried "apply update from ADB". When I try using either the adb push or adb pull I get "error: closed"
Thanks again for the help.
You have to use latest version of adb. Then you can login to phone via adb and find file you want to backup. Then use "adb pull" to get file to PC.
If you have custom recovery you also can make backup you data using recovery.
Also you can flash the same ROM you have without wipe data.
Hi,
my Nexus 4 is stuck in a boot loop since 2 days. I found it turned off and assumed it crashed (has done that once or twice before), but after turning it on it's gets stuck on the boot up screen. I've tried restarting it numerous times, left it on the boot screen for hours - nothing.
I can access the recovery mode and according to most things I've found while searching the internet for a solution a "wipe data/factory reset" would hopefully do the trick, but the thing is... I haven't backed up my device in ages. (Stupid, I know.) I'm travelling and took a lot of pictures that I would hate to loose.
Is there any way to save them? I don't care for app data or anything else.
I wouldn't mind rooting it (was thinking about doing that anyway), but I'm pretty much a n00b when it comes to Android, haven't done more with it than simply using it.
I have read up quite a bit about rooting in the last two days (here on the forum and everywhere else) but I'm still not sure how exactly to do it, since all methods seem to require unlocking the bootloader and therefore deleting my photos (or just don't give much in the way of explanation).
I'm using a mac, but if necessary I also have Windows installed. I have installed Adb and fastboot following this guide.
The phone is not rooted, I don't have developer options or USB debugging enabled and it's running on 4.4.4.
I would be really grateful for help.
If you can boot into the bootloader you can install a custom recovery, I'd recommend twrp. Then booting into the custom recovery you could use adb to pull files off your device . But your bootloader needs to be unlocked. If it isn't I'm afraid you won't be able to get your photos

bootloop issue
A.
Try to go into safe mode and backup your data.
Boot into Safe Mode:
1. Press/Hold Power button until power menu shows up
2. Tap/Hold Power off option
3. Choose OK to reboot in safe mode
B.
For bootloop problem:
Boot into Stock Recovery
1. Power+VolUp while booting to enter recovery
2. You can release buttons after you see Google on screen
(Note: Must be this sequence Press/Hold Power, THEN Press/Release VolUp, release Power)
3. Android fallen down screen - VolUp to toggle recovery menu
Now wipe Cache & Dalvik Cache in recovery and reboot the phone.
C.
If the (Option B) does not solved then try to flash the stock rom with the below given mentioned steps.
First download any stock rom and also the related usb drivers. Install the drivers into the PC.
Boot into the bootloader.
Open (fastboot.exe) Cmd prompt as admin. Put the stock rom into that particular folder.
fastboot flash bootloader filename.img
reboot the phone and return back to the bootloader.
Then, we will flash all other partitions.
fastboot flash radio filename.img
Again reboot the phone and go back into the bootloader
fastboot flash boot filename.
fastboot flash recovery filename.img
fastboot flash userdata filename.img
fastboot flash system filename.img
If you want to relock the bootloader of your device after flashing the device, put the device back in fastboot mode. Then type in the following command in the Terminal or Command Window you had opened earlier -:
fastboot oem lock
This will re-lock the bootloader of your Nexus device, restoring your warranty and putting the device back to complete stock.
I hope this helps you out.
Thank you, but is there a way to boot into safe mode if the phone isn't turned on? I can not get to the power menu since I can't turn the phone on...
I can only access the recovery menu.
Data backup
Alternate method you can do is that you have to download a software by name 'DROID EXPLORER' - (try to google it) you will find this software from the internet. Then install the software on your PC or Laptop. Once you open the software it will take some time to download the sdk files from the internet then install the windows sdk files also.
Later you go into the recovery mode with the usb cable connected to your PC. Then open the Droid Explorer software you will see your phone connected picture. Now double click and open it go to sdcard and copy all your pictures and other files to your system.
Finally, Once you backed up all your files now you can reflash with the proper rom from the recovery mode. From directly inserting the rom.zip file into the sdcard and run the custom rom after you wipe the partitions properly in recovery.
Note: Before wiping the partitions always unmount the system, data, cache and then wipe it.
Ok, I'm going to start by explaining everything I did up to this point to eliminate any troubleshooting sugggestions i may have already done.
I rooted and installed recovery the same way everyone else did. After a couple of days, I tried to install a ROM but im assuming i was encrypted because i was stuck in a loop that would only boot me into TWRP. Did my research and took the necessary steps to get around that and decrypt and boot into the new ROM.. FINALLY!!! Only one problem, this rom doesn't have Super SU installed, Alright... so i download the proper Super SU build and put it on my Micro SD card and try to boot into TWRP to flash....
This is where the problem begins. I never get the prompt to authorize my PC from my phone to allow anything, and i never did each time i reset. I'm almost certain the adb on this rom is messed up, i've wiped about 4-5 times to re-enable usb debugging from scratch in order to adb or fastboot into recovery via command prompt, however when i try adb, i get that unauthorized error an there's no option on the LG V20 to revoke under developer settings. Fastboot i just get the same "waiting for device" message. Also keep in mind that i set it to photo mode, every mode that was available and nothing. Tried different USB Cords and did this on both my laptop and my PC at work
I've tried uninstalling and reinstalling all of the drivers, re-installed the latest version of adb and fastboot to my PC, that didn't work either. Tried deleting the adbkeys file in the .android folder and still nothing.
When i try to boot in recovery manually, i just get the wipe data option and when i click yes to everything, it actually wipes my data. I'm unable to reflash TWRP because I can't access ADB or Fastboot due to the unauthorized error.
Someone, PLEASE HELP!!!!
any luck?

different route but im in the same boat. any luck?
I fixed this shortly after. Wanted to avoid returning to stock as. The only option was you and I was on 10d. I had to go back to stock but luckily the recovery method still works.
How can I relock the boot loader and restore my Stylo 2 to factory default? Provider is T-mobile.
fastboot flash oem lock.
Note however if you used twrp this will brick your device unless you flash the original recovery first. Provided you got the kdz or LG bridge you should be able to just lock put in download mode and use the repair recovery option.I'm not responsible if you brick your device. Good luck

I had used LG Bridge to reflash my phone so I believe that I have original recovery on the phone. How can I verify?
When I enter fastboot flash oem lock I get < waiting for device> on my terminal screen and thats it?
Once you have the phone wiped completely back to default (including recovery) with the LG tools. Enable developer mode, and then enable USB debugging. While it is plugged into your PC navigate to the folder where you have the ADB applications in CMD or add the location to your Environment variables. The latter will allow you to launch ADB/fastboot commands from any location in CMD. I definitely suggest this. With your phone connected run "adb devices" to make sure that it sees your device. Then run "adb reboot-bootloader" to reboot into the bootloader. While on that screen run the command "fastboot flashing lock_critical". It should prompt OKAY then give the time it took and also that all of the user data was deleted. Then finish up by typing "fastboot reboot". That will put the phone back into a normal mode. Boom, you are done.
Help
When I use the fastboot oem lock, at the moment when I power on the phone in the screen appears the text "Your device has failed a routine safety check and will not boot.
This may be a temporary problem.If this message occurs rerepeatedly, visit this link on another device and refer to the Red case: g.co/ABH
I have two days looking for the solution, and I didn't found anything
Hi
I would like to ask for some advice.
I've recently soft bricked my MI2S. I can boot to recovery (TWRP 2.8.1) and fastboot. The phone isn't recognised by Windows or Ubuntu, so I can't flash anything with fastboot. Actually, fastboot, adb or MiFlash don't detect the phone. I've tried to use a USB stick with an OTG cable, but TWRP doesn't detect the USB stick. If I boot to system, it stays on the MI logo (I can wait a full night, it won't change).
My question is, do I have a problem with my USB port? I'm equipped to solder a new one, if necessary. Or is my connection problem due to another reason? I wouldn't want to go through soldering if it is for nothing. Especially, when I started to mess up with the phone, it was locked with a different MI account (it was my wife's account, but it took me a few days to connect the dots together), and I couldn't connect with MiFlash, adb or fastboot either.
The steps I did to get it soft bricked:
Flashed TWRP 2.8.1 with fastboot
Rebooted to recovery
Rebooted to MIUI (a few times)
Attempted to flash TWRP 3.5.0 (my memory fails a bit there, I think I did it via fastboot)
The last didn't work because I'm still on TWRP 2.8.1
And I can't add any more zip file to flash via recovery, nor can I use adb sideload or flash with fastboot.
Any advice or comments are more than welcome. You may just have an idea that I didn't think of.
Regards
Matt
Quick update:
I don't know if you would agree, but I can't see my issue to be a software one (the device not being recognised)
I've ordered a USB port directly from China and I'll see if I can unbrick the phone from that point.
It's great that you can still access to recovery and fastboot.
First, I advice you to back up your data.
If you cannot use adb sideload or flash with fastboot.
Try in fastboot mode
- fastboot erase cache;
- fastboot erase system;
- fastboot erase userdata.
See if that can solve your issue.
