Hi.
Phone completely dead after software downgrade.
It does not even display charging after connecting it to a computer or charger.
However, if I connect the phone to the computer, it can be heard that the device is detected and after a while removed and so it loops endlessly.
I have tried several flashing programs before but none is able to detect the phone.
The phone's S / W is: 801CQNL238447
The phone is not the primary phone, but it would be nice to get it fixed.

Hello! here is what happened-
had my phone plugged into PC one night, screen froze to black and blue light stayed on all night, left it to drain battery to dead because none of the buttons were working, and the blue light would just stay on as long as it had battery
So now it doesn't boot, however when i plug it into my PC, the device manager will make the sound that its connected, and if i try to get into download mode while it's plugged into PC, the device manager will make a device disconnected sound followed by a device connected sound, much like normal when you reboot a device that's plugged in. However, there is no way to access anything related to the phone from PC while it's plugged in.
So is it hard-bricked? I already tried the firmware odin guide to unbrick but without download mode it's useless.
I also tried a new battery and several chargers/charging cables to get it to boot.
I never messed with any firmware settings/cfw or the like, and it just sort of died in the middle of it being idle.
Any help is appreciated, thanks!
I have a Note 7100 that suddenly decided to shut down and when I turn it back on, the phone is stuck in the "Samsung Note NT7100" logo screen. When I plug the charger in, the phone won't charge. When I turn the phone on while it's plugged in, it just shows the battery screen with the circle in the middle not moving.
And so, the phone is brought to me where I tried to do a factory reset/data wipe using volume up, home button, and power button. Upon trying to reset, I get multiple lines indicating E:\ fail to mount, E:\ fail to load, etc.
I then try to use Odin to flash another ROM but my computer is not detecting the phone. And yes, I have Samsung driver installed. The only thing I get is Windows saying it has found a new hardware named Samsung_Android and searches for updates but never finds one.
So the phone won't boot, won't charge, can't be detected by my computer. Is there a way to fix this? What caused the phone to shut off and the E:\ fail errors is unknown at this point.
eMMC chip got corrupted, change it at the nearest service center.
It's not completely dead I guess.
Yesterday, I went into odin download mode on the phone and plug the cable in from my computer. Opened odin and it detected the phone.
I tried to flash some firmware but it failed.
In odin download mode, at the top left corner of the screen, it's still giving me information of the phone.
Does this mean the phone is recoverable or is eMMC replaceable still the only solution?
It is not completely dead, it's just that storage memory is dead, unfortunately.
Hi guys, a week ago my phone H815 TWN started to act very strange.
Symptoms are:
1. Charging very slow and when unplugged still shows charging sign. (Fixed when remove battery but reoccurs when charging again)
2. On power off the phone reboots does not power off.
3. When battery is removed and placed back the phone boots without pressing any buttons.
4. When connected to PC via USB and then disconnected the USB connect manager notification remains active. (The phone is recognized from the PC)
Things I tried to fix the problem (unsuccessfully)
1. Cleaning the USB charging port
2. Hard and soft reset the phone.
3. Took the battery out for more than 10 min
I suspect that it is a hardware problem, as next step I am thinking to flash the firmware.
Does anyone experienced the same problems or has any idea what might be wrong?
Hi users, recently I wanted to go back form miui pie to oreo using this thread : https://forum.xda-developers.com/redmi-note-5-pro/help/how-to-revert-miui-10-pie-to-miui-10-t3940244
I had some problems with flashing, phone got disconnected from pc during fastboot flashing (loose cable) and after reconnecting I couldn't flash anything so I restarted the phone. Now all I've got is black screen (the backlight works but I can't see anything) I can restart the phone when holding power button and doing the combination of power up and vol+, but it's the same. If I connect the phone to pc in this conditon nothing happens, I can't hear any sound indicating that phone is connected, nothing in device manager, I even disconnected the battery and tried the edl pins but it's the same result, pretty weird. Can anyone give me any hint?

Yeah, but the point is, you can connect to pc and flash things and I can't do anything, I suspect my computer fried usb board or something on the motherboard bc it's impossible I can't get qualcomm hs-usb loader 9008.
As it turns out, after rebooting the pc, it doesn't boot anymore. Phone doesn't work and pc. Coincidence? formatting pc was needed (pc works now), could it be a virus or my power supply simply gave too much voltage to the usb? I was doing everything during the storm, y'know, thunders.. I don't know anymore, I tried even connecting to a different pc and the result is the same. I can't do anything on my phone, could it be broken usb board?
EDIT: It connects now in edl, I was shorting the pins incorrectly (can't touch the ground [shielding] while shorting the pins). Pls close this thread.
Hello.
I could really use some help/directions in recovering the bricked phone. Right now it doesn’t react to any buttons pushed (including power + Up/Down etc.) I think the issue is with the incorrectly processed boot/recovery layers/partitions.
What did I do?
The phone was fully functional, so it is unlikely a hardware failure. After flashing the TWRP to the recovery I was getting BOOT error (typical for lollipop), and attempted to fix it with autoRec.
After the phone turned off, it is not turning on again. Connecting it to two computers (Win 10 and Win 8) does not result in any new devices appearing in the Device manager. Shortening the second pin on the phone does not result in anything either.
When the phone is without battery and is connected to the PC it displays a battery problem on the screen – the charging symbol together with yellow triangle with a question mark (the only time when the screen turns on). If I connect it once again, when the second pin is shortened with the ground, the phone remains dead.
Currently I’m out of ideas, and curious whether the phone is already bricked for good, or there are still some other options left.
The Phone is D855 16GB version (most likely German).
Apparently the problem was with Win 8.1/Win 10.
For some unknown reason the phone wasn't identified even in Quallcom mode. I've made a clean Win 7 install, and then it did (after shortening of the second pin). Now it works.
