Background information:

Able to charge and connect to pc as a Qualcomm modem

My Oneplus 6 phone randomly after charging went black and was stuck in a bootloop, after a while I was able to escape the bootloop. Shortly after the screen goes black and now I am prompted with "Battery is too low" screen. After trying many other things of trying to recover the phone, such as: Fully draining the battery then charging it again, charging it for over 24 hours, to "trickle" charging the phone. I wasn't able to bring the phone back.


I don't really know if it this is a battery coordination error or an actual battery error. My goal is to try to recover the phone with no data loss, I've been looking around other forms trying to see how to recover data using QFIL of writing the storage then writing it back to the phone. I have also purchased a 64gb Micro SD card in hope of being able to recover the data using TWRP which I do have on my phone, but I am not able to acess recovery mode, because I am stuck in the "battery too low" screen.

Any help is appreciated. My current last resort option would probably be trying to "unbrick" the phone using MSM downloader tool. My goal here is to try to reserve the data on my phone and be able to hopefully revive my phone, because I don't believe I am in a hard brick.

it may be a stupid solution but have you tried pressing the power button for a while?

another solution can be addressed in physically removing the battery for a while. You'll need the glue or the new adhesive tape at least
yes I have tried the first solution but I will try removing the battery, cause I was able to open my phone up

also do you mind linking me the page / link to where the person fixed it by removing the battery. I would like to try to follow his/her solution

From the photo you provided, your phone enters Emergency Download Mode (EDL mode)when connected to the computer so you may search for related data about EDL mode.
Oh yea, I've already went through and finished with that incase I was in a boot loop, behind the battery is too low screen. I was successful in flashing stock rom onto my phone but I am still stuck in the battery is too low screen.

Then I cannot help you much but to make sure the battery is not the problem, you may have to replace the battery.

Sorry i was busy with an exam.

I've had a similar issue on a Sony Xperia Z2 and a Sony Xperia Z3 and after disconnecting the battery I've managed to solve the problem.
the oneplus 6 it's simplier to disassemble but i would suggest you to change the battery as said by @LR7875, just in case.
