Hello

I was installed a custom rom : lineage 14.1 and twrp 3.2..1
I wanted upgrade to lineage 15.1 but wifi and Bluetooth didn't work due to clean rom.
So i tried to install a stock rom with qfil.
Due to a Bad flash with qfil, tablet don't start.
I Think that it is bricked.
When i plug usb cable to charge, led flicks each second and no screen.
When i try power button, nothing.
When i plug usb cable to pc + vol up in qfil, led flicks and wi dows doesn't reconized qualcomm 9008 usb.....
How do i repair tablet and install stock rom ?
Thank you very much

Bricked phone qhsusb_bulk + power button works as vol up + power.

Hi. Well, i think im in very bad situation. Today my power button was working like vol up + power, i couldnt lock phone but i could wake up phone. I thought it's custom rom problem but... I installed custom rom + wrong kernel, then my phone wont run normally. I cant run recovery mode becouse of button/brick. When i've got download mode (i can run in with only power button) my PC cant see it, got drivers etc. so i cant flash it with kdz. When i turn on phone PC show me like 10 partitions and qhsusb_bulk in menager. There is no qualcomm mode in COM ports. What can i do now? I've got warranty for 13 months... Can i send it for warranty with broken buttons or what?
thanks...

Lenovo K3 (K30 W) /the same platform as A6000/

So i have Lenovo K3 (K30 W) and there is a problem!
The smartphone is restarting with logo. When i press the Volume + and Power button i go to a menu.
It shows that Volume+ is for choosing between the options (Recovery; Fastboot; Normal) while Volume- is for OKAY.
But when i press Volume- to select fastboot it does nothing. But the key should be working!
When i put the usb cable on the phone attached to the pc it shows the battery without to charge it.
I have installed drivers for the phone, but cant connect the phone with the pc and cant flash it.
I tried SPflashtool with rom for A6000 cuz i cant find rom for K3 with scatter file.
The main problem is that i cant reach fastboot because of the Volume- button.
Any ideas will be appreciated.
Also if somebody have rom with scatter file i'll be glad.
I hope that's a right place for the topic because i saw that the chipset and the CPU are the same as A600
Use qfil method

[Solved] Moto G4 Plus hard bricked after rooting : won't detect qhsusb

I tried rooting Moto G4 Plus and just after flashing the supersu and rebooting, it got bricked. Nothing shows except LED blink while connecting to PC/charger. Also, it won't detect in the device manager as a qualcomm device/qhsusb bulk or anything... I seriously need your help. Please help.
PS: I surfed over various related threads and all of them required the device to be detected on PC.
1) are you able to power off your device, then hold down the power and volume down keys? Does that boot you into the bootloader?
Or can you hold the power button for 1-2 minutes to force a hard shutdown, then attempt to boot into the bootloader?
2) did you flash a custom kernel before attempting to root? On stock Nougat for our device, you need a custom kernel.
The device is already in the switched off stage. When I press and hold the power button, nothing happens. When connected to USB cable, the front LED blinks. Nothing more. It doesn't return any sound or indication while connecting to PC. I tried installing various Qualcomm drivers to get it detected on PC. The Windows device manager shows nothing.
I tried this tutorial to root my device. I missed flashing the elementalx kernel during the root process. it caused the brick.

That tutorial should work, provided you flashed the ElementalX kernel before rooting.
Hmm, what happens if you try to boot by holding down both the power button and the volume down key at the same time? You should still be able to boot into the bootloader (with the AP fastboot secure mode).
What TWRP and SuperSU did you try to flash?

I used twrp and supersu as exactly as mentioned in the root thread (twrp-3.2.1-0-athene.img & phh's supersu).
The key combo doesn't work either. No response. Is there any way to get it detected on PC?
I previously had it happened on my Yureka and I had to short the board to get it detected as a qcomm device.

That's odd, as that key combo should get you booting to the bootloader (as in the tutorial), which should then get your device detected via fastboot. Did your bootloader look similar to this when you were flashing TWRP?

If your device is still on, try a hard shutdown (hold power button 1-2 minutes until shutdown, verify it's off by connecting power, you should see the charging symbol come on), then boot by holding volume down and power at the same time.
You could also try a hard reboot https://motorola-global-portal.custhelp.com/app/answers/indevice_detail/a_id/110630/p/30,6720,9687
I just found that the volume down key is broken. I hope that's the reason it won't boot to the bootloader. Let me fix it first and try your suggestion.
And yes, the bootloader menu was the same as shown in this pic.
Thanks a lot for your time bro. Much appreciated.

I just disassembled the phone and flipped the volume rockers so that the volume down should work fine. Then pressed and hold vol - & power button. Violaaa. Got into the bootloader. On TWRP, Just wiped data and flashed the ElementalX followed by SuperSU. It's working super fine now. A billion hugs for your support.

Does not turn on after flashing rom

Hello, he flashed with my flash in EDL mode my Xiaomi Mi A1 and after about 400 seconds to success, my surprise is the phone is not only flashes the LED when connected in EDL mode to the PC.
In addition, there is no series of commands with the volume and power button, a part that has been tested to charge the battery, disconnect and connect it ..

[HELP NEEDED] Dead S10+ (SM-G975F)

Hey guys, I have a little problem and could need some Help fixing my S10+ (G975F)
What did I do:
- Flashed latest TWRP from TWRP.me + vbmeta
What happened:
- My S10 was stuck in a endless bootloop at the S10 logo, didn't boot to download mode or TWRP and my PC didn't recognize it.
My problem now:
I let the phone in that bootloop over night to let the battery discharge. Next day when it was powered of I tried entering download mode by pressing volume down + bixby and connecting the cable to my pc but the screen was just staying black, after releasing the volume down and bixby key but keeping the cable connected it started with the bootloop again, so right now there i'm out of ideas, I just can't enter the download mode or TWRP.
Any help would be really appreciated.
Best regards, Jan

Did you tried to enter recovery?
And BTW samsung download mode is super strong almost impossible to brick you aren't trying key combination correctly to enter download mode or recovery.
When phone is restarting to enter download mode
Just
Hold bixby, volume down and while holding these, put the usb-c cable in the s10+ when connected to the PC.

If I press bixby and volume down while being connected to PC I just get a blackscreen
What happened when it went to black screen instead of download mode? I mean what its shows in pc?specifically in odin? While on black screen try tu press volume up and to proceed download mode even though there is black screen if then it shows in odin then you can flash stock.
Did you unlock boot loader before flashing twrp? Did you?
any update on that?
