Tried to flash stock firmware to Moto G, stuck in bootloop - Moto G 2015 Q&A, Help & Troubleshooting

After a failed attempt to install SuperSu, bricking my Phone, I'm attempting to flash factory firmware I got from this thread here (Firmware I'm trying to flash is Bell Canada btw). I failed to root using the Windroid Toolkit, and I tried to flash using this tutorial.
After issuing adb commands to flash the files to my device, I rebooted it, only to find out that it is stuck in a loop (Shows Bootloader Unlocked warning, black screen, Bootloader unlocked warning again followed by an animation of the android mascot, with "Erasing" at the bottom of the screen, followed by a black screen, then followed by the start of what I just described").
What else should I try?
Thanks in advance.

At this point I would just flash TWRP and a custom ROM... or if you are set on stock, boot TWRP, wipe everything, reboot to bootloader and flash the factory images again.

Alright, thanks for your advice. I'll try it in the Morning.
EDIT: I followed your advice, and now my Phone is working now, running Resurrection Remix. Thanks for your help!

[Q] HELP stuck on google screen after trying to root with superboot

I tried using superboot to root my nexus s, but ended up with having a stuck google screen upon reboot.
Is there anyway I can recover my phone to the original state. I can get into the boot screen by pressing up volume and the power button and I have downloaded an original rom; however, I don't know how to upload this rom
into the phone.
I unlocked the bootloader, and have the android SDK installed. I do have a response when I use the command "fastboot devices"
Is there any possible way to save my phone? Please help, Thanks in advance
is there a recovery image saved under the recovery option?
Hey I'm having the exact same problem as the OP.
I don't have a recovery image saved in recovery, so I tried to flash the latest CWM recovery image through adb, but the device isn't found.
My phone was rooted, then upgraded to 2.3.4, then got 2.3.6 OTA, but lost root. Tried to root with Superboot and now my phone's stuck.
How can I get my phone to work again?

You have to flash CWM using fastboot, not adb.
fastboot flash recovery recovery.img
Once you have the custom recovery flashed you can flash superuser in CWM to get root back or just flash one of the custom ROMs that include superuser.
Yes, I did exactly that.
I really have no idea what I'm doing so I'm extremely grateful for people who do.
Thanks
I am in the same boat as these other chaps. After installing the 2.3.6 OTA update I tried to root with Superboot and now my Nexus S just sits on the Google screen with the open padlock.
I've tried installing CWM recovery, as well as the boot.recovery.img that comes with Superboot, and it seems to install successfully. After rebooting my phone still sits on the Google screen, however.
Am I doing something wrong here (I'd previously rooted with few problems)?
EDIT: I should mention that after flashing the .img I'm trying to boot into recovery - at this point it just sits on the Google screen.
EDIT 2: Never mind, I sorted it. I tried using a different recovery.img (from this thread) and I was then able to get into recovery and restore a backup.

[Q][SOLVED] Unlocked phone just keeps rebooting

Hey, I'm not really sure what I've managed to do, so any help is appreciated!
I have a UK Retail motog which I updated OTA to 4.4.2. I've unlocked the bootloader and flashed CWM from this thread: http://forum.xda-developers.com/showthread.php?t=2563599
I managed to mess some things up (can't remember exactly what I did now, I know I know... stupid.)
Anyway when I try to start the phone I get the long warning message about the bootloader being unlocked etc, then the screen goes black and it just reboots, again and again.
What should I do next? I still have access to the bootloader and recovery, so I hopefully all is not lost.
Edit: I should add, I tried to flash back to the stock 4.3 stuff from this thread: http://forum.xda-developers.com/showthread.php?t=2542219
But flashboot gives me an error about partition downgrade. I also tried flashing the system image itself but that didn't fix my problem.
Edit 2: Fixed by following these instructions: http://forum.xda-developers.com/showpost.php?p=49227024&postcount=127

Stuck on "Warning Bootloader unlocked" screen

Flashed “BETA-SuperSU-v2.66-20160103015024.zip”. System now stuck on "Warning Bootloader unlocked" screen. I can get to Android recovery. I did wipe cache but same condition exists. Is it safe to do a factory reset at this point?
Although I recovered by restoring a Nandroid backup, I am still curious if selecting factory reset from stock recovery would have worked, or is this not an advisable method for soft brick recovery?

Maybe I did not use the best words to ask my question. Can you recover from a system stuck on "Warning Bootloader unlocked" screen by simply doing a factory reset?
Did the same thing

I did the same thing could someone help me? I updated to 6.0 a couple days ago (I just got the phone) and decided to unlock the bootloader. Everything worked fine. I have minimal ADB and fastboot set up and all the drivers are set up properly too.
I then decided to flash TWRP. I didn't check "Read Only". Everything seemed fine. I swiped to reboot and was told to install supersu so I did and then rebooted.
Now I can't get past the white "Warning Bootloader Unlocked" screen. I can access the bootloader and TWRP, I'm just not sure what exactly to do next.
I have a Moto G 2015 2GB on T-Mobile USA

You should not have installed supersu. Not sure why that option exists.

Did you make a Nandroid backup before flashing SuperSU? If so, restore your backup and start again.

I do not have a back-up :/ Is it still safe to flash the 5.1.1 stock firmware if I was already on 6.0 via OTA? I tried a factory reset in TWRP, but that did't work.

If you are going to reflash, why not 6.0 firmware?
Is flashing my only option since I have no back-up?

I haven't been able to find the 6.0 stock firmware for it. only 5.1.1
If all I have to do is flash 6.0 stock firmware and my phone is fixed could I do it in TWRP? Like, just drag the firmware into my phone's download folder and just install in TWRP?

Yes you can.
Edit - My phone was also stuck at this screen only - "Warning Bootloader unlocked"
I also soft bricked my phone 3-4 days ago but got it back.
Follow below steps and you are good to go -
1. Download and install Motorola Moto Drivers
2. download stock firmware from http://forum.xda-developers.com/2015...mages-t3169639 for your Moto G3 model (in my case it was XT1550)
3. download TWRP from http://forum.xda-developers.com/devd...1051#downloads [ i used twrp-osprey-2.8.7-r5.img version ]
4. download SuperSU from http://forum.xda-developers.com/show...25&postcount=3 [make sure you download BETA-SuperSU-v2.62-3-20151211162651.zip version only else you'll again brick your phone]
Now as you have all required things to get your phone back, now follow below steps -
Now flash stock ROM, Instruction here -> http://forum.xda-developers.com/2015...ctory-t3187750
Now flash TWRP - fastboot flash recovery your_recovery_name_here.img
now start your phone (takes 15 minutes around)
now go to recovery and flash BETA-SuperSU-v2.62-3-20151211162651.zip and start your phone [ do not allow TWRP to root your phone when it asks you to root your phone just tap not now (or whatever i don't remember right now)]
Starting up phone now takes 25-30 minutes approx.
Rooted
[Don't brick and blame me , do it at your own risk ]
The point where things went wrong was that last screen where TWRP asks you if you want to root the phone - NEVER let it do that, ever, even after you properly root it the right way (which is manually flashing that specific version of SuperSU or a later version).
I've had instances where on a random reboot into TWRP - on a properly rooted Moto G3 - where that question screen comes up. It should not come up when the phone is actually rooted but I've seen it once or twice. Again, the point is: NEVER EVER let TWRP do it's own internal rooting process because that's what breaks things on the Moto G3.
- flash stock firmware complete
- go back and flash TWRP
- use TWRP to manually flash the SuperSU version (at least 2.62 beta which is what the Moto G3 running Marshmallow requires)
- make sure after that flash of SuperSU you do NOT use the TWRP option to root the device when you close out TWRP, ever
- flash a replacement logo so you don't see the bootloader is locked splash screen
That's about it.
I just unlocked BL. How long does it take to restart the phone from ADB recovery screen? Seems like forever.

It is basically a factory reset. Not sure you need adb at this point.

I kept holding pow button, it kept restarting back to the same BL unlocked message, then finally booted back to MM. Took a while i thought i bricked it.

I Need Help Fixing Bootloop

So, I think I really screwed up. After I finally got my bootloader unlocked, (after some trouble) I tried using Kingroot with no luck. And me being the eager beaver that I am, I attempted installing TWRP in Flashtool with the "Select system to Flash" option. Now I'm stuck with a big fat "SONY" on a white background.
Whenever I tried installing TWRP with "fastboot flash recovery TWRP-3.0.2-4-kagura" I'm stuck with < waiting for device >. That's why I tried flashing through Flashtool.
I'm on F8331.
Any help would be much appreciated.
EDIT: I got TWRP working, and I'm able to boot into it. Now I'm guessing all I have to do is install SuperSU, and maybe flash a custom ROM?
Hi, are you tried with Flashtool with an Marshmallow firmware?, when I bricked my phone (F8332) the only solution was this.

First of all reflash you firmware using flashtool, reflash the twrp recovery that corresponds to your firmware then flash the supported androplus kernel for your firmware. After all the steps above access the recovery and try to flashing the latest supersu available. Your very welcome.
I ended up just flashing XplayZtation.

Samsung Galaxy A11 in boot loop after root attempt

I hope you guys can help me with this one,
I followed the guide on Magisk website: https://magiskupdate.com/root-samsung-galaxy-a11/
Everything went well up until the final step which is titled: "Re-installing the Magisk App". This is right after I've flashed the patched boot image which was successful, I then proceeded to reboot the phone into recovery mode to reset to factory default and now I get the Samsung logo when I boot the phone, I get the alert that I'm not running official software and then it just loops through the boot sequence again and again.
I tried flashing the boot image again and again but without success.
Did I brick it? Can it be salvaged?
Thanks!
Re-flash phone's Stock ROM to get rid off of all modifications you applied so far.

You haven't unlocked your bootloader, that is why you are getting the alert that says you are not using official software. You have to unlock your bootloader before you can successfully flash a Magisk patched boot.img, it doesn't work on devices that have a locked bootloader.
As stated by the member that posted above me, flash your stock firmware to fix what you have corrupted. Then start over by finding a way to unlock your bootloader, once unlocked, you can try flashing the patched boot.img again. If you cannot find a way to unlock the bootloader, you will not be able to successfully flash and boot the patched boot.img.
