[CLOSED] Phone probably hardbricked - Android Software/Hacking General [Developers Only]

Hi to all, yesterday I tried to root my phone following a guide here on XDA Developers (I don't remember which one). I have a Pixel 6 Pro and I tried to flash boot.img when the phone, after being restarted, starts to bootloop and then I try to turn it off. Then, the panic. The phone doesn't seem to be recognizable by ADB nor fastboot and the screen is permanently black. When I try to hold Power button and other combinations (while plugged to my PC) Windows emits some system sounds like "plugged" or "unplugged device" but I can't find my phone like recognizable.

[Q] Desperatly Need Help Getting Into Bootloader

Hey everyone, so it's been a couple of weeks now since the power button on my Nexus S stopped working. It wasn't much of an issue since I began using the volume controls instead to wake up my screen. However, I'm stuck right now. I was pleased to see that in clockworkmod, you didn't need to use the power button to select anymore...so I went ahead and flashed a rom. The problem is, I completely forgot to flash gapps so now I can't get into recovery mode in order to flash it since my power button is broken. I got into recovery mode by using the Rom Manager app but since I don't have gapps flashed, I don't have the android market. Could someone please help me, I'm not sure of another alternative to get into the bootloader without using the power button. Thanks in advance

replace power button
sorry but i cant help you
try to do it with cmd orders
download adb package and use this order:
adb devices
adb reboot-bootloader
if you have the official cwm app go into the app and select download rom from there you can download gapps and flash it from cwm once it has finished downloading when your phone rebbots it will start with the android welcome asking you to enter you gmail details

I've always had bad luck with adb but I'll still give it a try. Does my device need to be turned off before I enter the command? It's hard to turn off my phone since the power button isn't working, and when taking out the battery and putting it back in doesn't help since the phone just boots up automatically.

[Completed] Android boot loop - is my device dead?

Hello All,
This is my first post at this forum.
I've come to a point where I'm on the verge of giving up.
A few days ago my Nexus 5 entered a boot loop without me doing anything special with it - it was just in my pocket.
All see is the google logo for a few seconds , then the screen goes down for a few more, and back to the google logo.
I'm able to go into fastboot by hold down the volume down (only) button when this happens, but the boot loop happens when I choose to boot into recovery mode.
My device has an unlocked bootloader.
I have fast boot access and no ADB (ADB wait-for-device doesn't work).
Went over a tutorial from androidforums.com and flashed a completely new image using fastboot.
The entire process worked, but the phone is still at the same state.
I've read that there is and issue with the power button on these devices - so I tried all methods of knocking it against stuff without success.
I've taken it to a lab nearby and the guy there was sure it was the power button. He said he fixed about 50 of these already - after a few hours he called me up and said he had replaced the power button 3 times and he's giving up.
in short , this is the current situation :
1. Device stuck in bootloop - only google logo is seen
2. can boot into fastboot (and have fastboot access from PC) but can't boot into recovery
3. flushing a stock succeeds but won't help
4. power button seems o.k.
I am about to call this a bricked phone and look for a new one but something inside me tells me that this might still be a software issue and can be fixed.
I would be happy to know if there is a way to know what is failing in the boot sequence. or maybe load a debug application on to the device to check the HW. I've yet to find any help in that direction.
I'm a software eng. working in the cellular comm. field, so I'm up for anything that anyone has in mind.
Thanks,
Ran.

Hello, and welcome to XDA!
It does sound like a hardware issue and it could be the power button, except for one thing: wouldn't a held down power button in fastboot cause a shutdown as well? Maybe not, but I thought I'd ask that.
At any rate, better to get an opinion from someone who actually has the deivce. Please create an account (so you post in other forums) and then post in this thread (can copy and paste from here):

Hope this helps, and good luck!

Is my phone completely dead or still bricked?

So this is what happened
I was charging my phone via portable charger and it suddenly crash into QUALCOMM Crashdump mode. I try rebooting but could only enter fastboot mode
So i used MsnDownloadTool to flash back the original Oxygen OS and it worked for the first time. I update the OS via software update and restarted my phone.
But i forgot to exit the MsmDownloadTool and unplug the usb cable... So MsnDownloadTool reflash the stock os again. This time, my phone hang at the setup wizard and went dead
So my current state of my phone
1) Cant enter recover mode/fastboot mode
2) Phone doesnt vibrate/or power off when i hold the power button
3) It is just a black screen with a white-ish/blue-ish led light
4) When it connect to PC, it is showing as Qualcomm HS-USB Diagnostics 900E
5) When i connect to PC while holding Power Off + Vol Up, it will still enter QualComm HS-USB QDLoader 9008, However, even if i try reflashing hydrogen/oxygen OS, the result will be the same.
After the flashing is complete, the screen will remain black and the led color will remain as white-ish/blue-ish
So is my phone completely dead? or is there any other solution that i can try?

You said you updated the phone. Maybe you need to find the tool with Pie in it already. I don't know if the tool will roll back, but I know a lot of people had issues like yours when they tried to roll back to Oreo by just flashing in TWRP. See how they solved it back then
hi. i have already sent the phone for repair and they replaced the entire motherboard
thx for the help anyway!
closing thread
had op5 with same issues. lucky me, i have service box for working with efs partition. issue is that you will need to format whole phone with msmtool (red screen at flashing after entering service mode: verify hash, smt download mode, code "t****" and selecting your phone storage capacity, but then you'll lose imei, wifi, bt calibration. good luck. fixed 15 pcs OnePlus devices with same issues as yours.

I have similar issue on OP6.
Can you give us instructions how to perform format of whole phone with msmtool?
You can find unbrick guide for OnePlus devices here, it's the same process for OP5 and OP6 :
https://www.google.com/amp/s/forum....5t-unbricking-tool-confirmation-t3733012/amp/
Edit : BTW, if MSM tool doesn't work, you may give a call to client support...
Unfortunately MSM tool helped me downgrade the system but main problem with app crashing is still present

[CLOSED] Dead Amazon Fire HD 3rd gen

Hey,
i tryied to root my fire and the result is = it's not starting anymore.
I have a black screen.. If i connect it to the pc, i'm able to turn it on, but it's disconnecting instantly afer half second and connecting again.
The only way to disabling this loop is to to hold on/off & vol - for 5 sek. The same way to start this loop again.
Normal USB- and Fastboot-Cable does the same.
Anyone some idea how could i try to fix it?

You'll be better served here, if you open a thread, under the Questions & Answers section from within this forum https://forum.xda-developers.com/c/redmi-9-poco-m2.11167/
If you want to enter to fastboot mode, pressing the volume down while connecting to the PC, is also a valid option.
