Device Boot Looping/Soft Brick

I decided to unlock the bootloader so that i could flash TWRP recovery but after unlocking the bootloader on my device, it has been stuck on the logo screen with "powered by android" under it. I have tried using fastboot to clear userdata & cache but that just leads to my phone again being stuck on the logo screen. The device also can't boot into recovery. When I chose to power off in fastboot it causes me to be stuck on the logo screen. Any help is appreciated I am on android oreo btw

Did you try a back to stock zip? go to fastboot and run flash-all.bat, while your device is plugged in ofcourse.

Let me guess.
You unlocked the boot loader and flashed TWRP and now you are looping, right?
There is no compatible TWRP that is compatible with Oreo on this phone.
You cannot leave TWRP installed. You can only install it along enough to get the recovery to boot.
You then must flash the stock boot image.

I had this problem tonight also. In my case I suspect it had to do with the install of magisk in which I checked both boxes and patched the bootloader. on reboot I was stuck on boot. Just wanted to add my solution. I got the pie back to stock zip here https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681 then I put it into the adb folder and ran the flashall.bat script. I tried the no wipe one and it saved my information. very happy I didnt have to resetup my phone in the end.

did you remember to flash a stock boot.img before flashing magisk (to clear TWRP?)

A2017G only EDL mode available, need help with brick

Hello
Long story short, i digged out my axon 7 to use it with some music apps.
I wanted to return the phone to stock firmware, it had unlocked bootloader and running a custom nougat rom (AEX i think).
I followed this thread: https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-universal-unbrick-t3814413 and flashed full EDL package.
Now when i try to turn on the phone, or enter recovery i see the boot logo and quick flash of the commandpromt with a broken droid and the phone turn off again.
I can still enter EDL mode and flash the phone.
Any ideas how i get it up and ruunning gain ? preferably on stock firmware
Thanks

Use one of the less archaic methods:
Download "EDL Tool" from the ROMs, kernels, development section, along with an EDL package that goes with your phone model. Put your phone in EDL and just flash it with that tool. after that, if it still doesn't boot you have to format data, because you might have conflicting data. If you can't do it from EDL Tool (i think you can, don't remember) just enter the recovery with Vol+ and Power and make a factory reset

My story is very similar and now i'm stuck in EDL mode. I was able to flash stock Oreo B02 EDL package successfully and boot into OS. But after i was trying to unlock bootloader and reboot to recovery, ZTE logo appears for a second or two and then following error message starts looping:
(broken droid logo)
No command
Supported API: 3
E:failed to mount /cache: Invalid argument
E:Can't mount /cache/recovery/last_locale
EDL mode works but if i flash EDL package or boot/recovery again nothing changes, i still get the same error. Can't boot to OS any more and recovery does not work - screen just stays black.
So what are my options now to get it to work again?

From some other threads, I believe you could try to EDL flash Nougat instead of Oreo, it would work better.
https://forum.xda-developers.com/axon-7/help/help-edl-factory-restore-stuck-device-t4031619

I did that already but no luck, i still end up with the same error.
Is there some way to reformat or clean up internal storage completely in EDL mode? It seems that some garbage left behind by trying to unlock bootloader is surviving even EDL ROM flash and breaking OS boot.

According to other threads, the problem could be due to "sparse" structure while flashing.
I suggest the following:
- Use Axon 7 EDL toolkit to flash latest official TWRP recovery (for Oreo a specific TWRP would be requied).
- Inside TWRP then wipe data/factory reset and at the utmost Format data. Then retry to boot.
- If not OK, reflash with EDL full ROM and try again.

Already done that for several times with O ja N EDL rom's but no luck. Can't get to recovery nor make system to boot.

Did you successful unlocked bootloader?
If not, I would recommended Axon 7 EDL Tool by djkuz, flashing nougat edl package and unlock it through the options.
Can you get into stock recovery after flashing EDL package? It supposed to have a format option for userdata and cache.
Did you try to get into fastboot mode? Power + Vol up buttons if i'm not wrong.
If so, you could try to format these partitions.
fastboot erase /cache
fastboot erase /data

I have experienced the same problem but I have resolved flashing, with Xiaomi MiFlash (sometimes I use this program because occasionally flashing EDL packages with AxonEDLTool, it gives me problems like this) this package Axon7_RR-O_B32-B10_TREBLE-Ready_Oki20180803_FULL_EDL.
With this EDL, if the flash is successful, you will find NFound recovery 3.2.1-7 installed with which you can make a complete wipe and / or format them with the file system you prefer.
Afterwards, using MiFlash or EDLTool at your discretion, you can flash the EDL of the original system if you prefer.
I'm not an expert but this has solved my problem.
To unlock the bootloader, if the unlocking with EDLTool does not go well (it happened to me just yesterday while I was installing a Rom on another Axon 7), you can use Axon7ToolKit 1.2.1, it always worked well for me.
I hope it can help :fingers-crossed:.

Hi, just want to let here my solution for the same problem, it may help others.
I tried to flash A2017G_B10_NOUGAT_FULL_EDL and A2017G_B02_OREO_FULL_EDL but always getting the Can't mount /cache/recovery/last_locale error, phone completely bricked.
So I flashed A2017_B13_FULL_EDL_UNBRICK_DFU using MiFlash through EDL, you can find this here: https://forum.xda-developers.com/axon-7/how-to/a2017-4th-category-brick-repair-manual-t3585898 (if your EDL mode works fine there is no need to disassemble the phone as shown in that tutorial)
Now the phone is completely working, recovery and system, but everything in chinese.
Then I flashed A2017G_B02_OREO_FULL_EDL using MiFlash through EDL, and now everything is working and in english

Thanks a lot for the tip! A2017_B13_FULL_EDL_UNBRICK_DFU did the trick and unbrick the phone.
What i did:
1. used MiFlash to flash A2017_B13_FULL_EDL_UNBRICK_DFU
2. after that A2017G_B03_OREO_FULL_EDL
3. reboot to recovery and performed factory reset
First time I did not perform the factory reset and got stuck on the boot picture without the reset function (power button did not work). Drained the battery and performed factory reset and got the phone working again.
update:
Phone is not stable on B03, some apps crashing from time to time for no apparent reason and also soft reboots happening randomly.
Now I got stuck on the Axon boot screen again after rebooting the phone manually and waiting for the battery to drain ...
i did not install or perform any custom action to the system, just regular use and apps, but it is still acting up badly.
I was planning to use this phone as a secondary handset because it is actually a very nice piece of hardware but now i am starting to have second thoughts about that.

Stuck in black screen, can't boot into fastboot mode

I got my Mi A1 today and it came with Android 7 installed, so I decided to install LOS. I unlocked the bootloader and then I booted into TWRP using fastboot (I didn't flash it), it gave that "system is read-only" warning. I tried to reboot to system without doing anything and it was stuck in a boot loop. Then I booted into TWRP again and flashed LOS sucessfully. When I tried to flash gapps, however, it failed claiming I was still running Android 7. I rebooted and it booted sucessfully into LOS, but that was the last time the phone ever booted. Now it shows the unlocked bootloader message and then gets stuck in a blinking black screen. I can't even boot into recovery or fastboot anymore.

It seems you will have to flash stock ROM using Mi Flash (no idea how to use it so search it) and, once is done, flash LOS again.

I somehow managed to get to fastboot and then I used MiFlash to flash the stock rom. I'm back to the bootloop, which is an improvement, because at least I can consistently get into recovery and fastboot.
The phone got stuck in that black screen after I tried to flash LOS, should I actually do it again?
EDIT: I flashed the stock rom a second time and it's working again. I don't know why, but I'll take it.

Update to stock Pie before trying to reinstall LOS again. Hope this time works.

You should install 1.0.8.0firmware first before install 9 ROM!?

Question Help with Nothing phone stuck in Fastboot mode (A13 Beta 1.5.1)

Hello,
I was trying to downgrade my phone from the beta to Android 12 and it's now stuck in Fastboot mode. Won't let me enter recovery. Tries to boot but just stays on the nothing logo. My bootloader is unlocked. I'm assuming I need the same firmware I was running to reload onto the phone. Any other files needed?
Thank you so much! cheers

I can't enter recovery mode. Only fastboot.

Flash boot and vendor_boot and you'll be right back in recovery
If it's not booting try set active slot to either a or B and flash the images mentioned above

I'm having a similar issue coming off a fastboot stuck device. I guess I managed to delete the recovery mode from slot B so I can't get into fastbootd to flash some of the lower level partitions to make my fingerprint sensor work.
The vendor_image is the recovery?

Did you guys find any solution? I am stuck with my phone stuck in the bootloader mode and I can't seem to do anything.
Here's what I did:
1) Unlocked bootloader while being on NOS 1.5.1 Beta. Successfuly did it.
2) Restarted my phone to bootloader mode and flashed dtbo, boot and vendor_boot from SuperiorOS 11th Feb build.
3) Proceeded to restart to recovery as mentioned in the instructions but instead of restarting to recovery, it restarted to bootloader.
4) Stuck in bootloader mode ever since!
Nothing seems to be working. I have tried literally everything but cannot get past the bootloader. Please help. I don't have any secondary device to use.
