Note 10.1 N8000 Won't start

Hello,
I tried to update my note 10.1 gt-8000 today using the instructions from droid opinion website. I did not remove any partition or stuff. Just uploaded the rom Image in AP, selected auto reboot and F reset time and this i. but when the phone went to restart, it wont start again. Its been 30 minutes and phone is still off. I press the power button, volume + power up or down but nothing happens. Is my tablet hard bricked? Any idea whats wrong with it? Please help me
Edit: I just noticed when I also put it on the charge, the screen doesnt turn on to show charging. So it doesnt even charge, the odin console had 1 pass and 0 fail. Any idea what went wrong?

Go back to Droid opinion they are responsible .
Reread and double check instructions and correct firmware for your phone .
My guess is wrong firmware what was the original firmware .

Thanks for your reply. So it means its hard bricked? When i plug in the charger it dont even show charging sign. Any way to fix it?

Does Odin work? If it works, try to re-flash your device according to the instructions. Otherwise, install the stock firmware.

Sure, I can help you.
What OS do you have? Try to install Fastboot and ADB tools. After that, enter in download mode (not recovery!) and connect your device with computer.
ADB Devices will test the connection.
Next use Fastboot to flash.
If you have questions, pleask ask them. It will protect you from wrong actions.

I got mine working by opening the back cover (check instruction from Youtube)
unplug the power plug (the black small block in the middle with Red/Blue/Black colour cables), leave it for few minutes, plug it black.
This will only work if you have the "Samsung Note 10.1 logo" flashing in loop on screen all the time.
Good luck

Please help me

Hi
I've made a bad mistake which I'm hoping people can help me with. I tried updating my phone wit MIUI 8 as I had an issue with my battery. My updater app on my phone was not working so I downloaded zip file and tried doing it manually from the app. Then my phone just turned off and I'm unable to turn on or charge. None of the button combinations work and when I plug in to my laptop through usb port I get a message saying it doesn't recognise device. I've tried using unlock function on website but get error messages in chinese around ip address to malfunctioned phone number so no luck there.
Appreciate any help as I had a lot of information, apps and data that i would hate to lose. I lost my wife 3 months ago and I have some precious memories on that phone. I know I should have done a backup beforehand and that was stupid of me.
Is there anyway i get can my back in without losing data. if not then anyway at all to get my phone working.
Thanks, from a very down MI4C user

Try holding one of the power buttons(don't remember which one) and plug in the cable so the phone boots into fastboot mode. If you manage to get into fastboot boot TWRP and copy your files straight from it as it has mtp support. If your PC sees your phone as an unrecognizable device there's a big chance you can recover your data. Last hope would be to use a modified usb cable for edl flashing although this way you'll most likely lose your data.

Thanks, first suggestion doesn't work unfortunately. I have now been given permission to unlock bootloader but problem is the device is not recgonised due to usb issue.
So I cant turn on, won't charge etc and none of button combinations work. Has anyone encountered the issue with usb before. Unsure of 'modified usb cable for edl flashing'. All very frustrating.
thanks for any help

Anyone else have any ideas. Desperate here without my phone and important data

Have tried everything at this stage...utter despair. My phone just won't turn on or charge or enter fastboot mode etc
Anyone please help

The modified USB cable that I spoke of is used to force boot the phone into emergency download mode. It's baisicly a last hope flashing method that should work regardless of how broken the phone is. The only downside is that using this mode you only can flash via miflash and this will wipe your data. As for the cable you can either make one (look for deep flash USB cable schematic, it involves swapping 2 wires) or just buy one. Once you get into edl just follow the unofficial bootloader unlock guide to flash the 6.1.7 rom as it is flashed in the emergency mode.
Edit: whenever you plug your phone into your PC does the screen or led diode light up at all? You can also try holding vol- and power button and plug the phone into a charger (not PC) to see if it will respond at all. Charger gives more current so maybe it will force the phone to boot.

Thanks Adi. I don't think I will be able to make one. I've seen some threads elsewhere about getting into EDL mode, do you always require modified cable to do so?
Nohting happens when I plug it into PC, no lights etc. Tried charging using normal power supply but nothing happens either. Have even tried connecting to powerbank overnight but no power is taken from it.

So there is no "unrecognized device" popping up in windows anymore?
If so, let the phone lie for 1 more day (without connecting any power sources to it). Afterwards charge it (with a normal charger and a cable that works for another phone) for about 2 days (or until you see the notification led charging). if nothing happens you can try a different charger or an usb port for another 2 days.
If your computer recognizes the device ("unrecognized device" or just any reaction by connecting the phone) try to reinstall all the drivers (xiaomis/qualcoms, as well as adb, fastboot) and see if there is something happening.
Report back if it helped.
Edit: Did you try different cables? had similar problems with op2 (not recognizing) with xiaomi cable...
Edit2: to make sure the device is completely dead, use a linux distro (e.g. Ubuntu, ensures that there are no driver problems, you can install it on a usb drive) and a cable which surely works (try it on at least 2 other phones, if data transfer works its ok) then first install fastboot (ctrl+t to open a terminal) by copy/pasting "sudo apt-get install android-tools-adb android-tools-fastboot". Afterwards hold vol- and power button for at least 12secs and plug mi4c in (release the buttons after plugging it in). Now you can run "sudo fastboot devices" and see if there is sth listed (should even recognize it in edl).

You don't need to use the modified cable as you can enter edl from fastboot, but the cable method is used to force the phone into it if you can't enter it the normal way. As for rescuing it, try the method @wertus33333 suggested.

Might have bricked my phone?

I was using lrteam twrp 3.4.2b-1206 and I was sideloading the vendor update for 12.2.1.0 when the progress bar froze. I gave it 10 minutes and held the power button to reboot and now the phone is showing no signs of life i cant get it to even show the poco screen. I've got no ideas left on what to do.

So I just took the device apart to try and get into qualcomm edl mode through hardware and now the front camera led turns red while charging. apart from that there are no signs of life though it won't show up in my pc's device manager even though I have the qualcomm drivers

It's not booting, he doesn't want to get into edl. It's showing no reaction. But he could try pressing power button for 1min and look for vibration

To try to restore the phone yourself, you must use commands in fastboot or adb.

the power button for a minute didnt do anything either sadly. Im trying to get into edl so i can try and recover it with QPST, but even after opening the phone up and trying to get into edl through hardware, i was only able to get the red charging light to start showing whilst charging. Should I try to disconnect and reconnect the battery maybe?

Yep, can't hurt at this point.

You can try this:
Recharge the battery for at least 1 hour (even if you think it is already charged)
after connect it by usb and press the power button first,power button with volume -, button with volume +, and try to see if it appears on the pc and in what way.

Hard brick without fastboot enabled

Hello guys.
I need your help. My phone bricked itself. I left it on charge for the night and faced a black screen issue next day. Bootloader is not unlocked, so I can't enter the fastboot mode. When I press and hold all three buttons I see Mi logo for some time and nothing after. When I connect it to PC via usb it connects after some time but almost instantly disconnects. During that short period of connected state I see usb serial device(COM7) in device manager which disappears then. Then 20-40 sec pause and the same connection and disconnection. Of cource, miflash doesn't see it at all when I try to flash it. I have no experience with disassembling so I cannot flash the phone using motherboard directly or try to enter fastboot by pulling out and in battery. Any thoughts what it can be and how to fix it? Appreciate any helpful info related. I saw a bunch of articles and cases but everything got stuck because of that frequent usb toggling. Not much you can do when you can't even connect

Excuse me, but, there are a lot of errors and misunderstanding in your post, so you should need to sort them out, to can advance on this.
Fastboot doesn't need to be enabled, fastboot is always there, you just need to press the right buttons to send it to this mode.
USB debugging enables the ADB connection, most probably, you don't need it to fix your device.
Although this said, keep in mind that your device must have the bootloader unlocked, in order to use fastboot to flash.
If this is not the case, then you should need to use a different mode, the EDL mode, also called QHUSB-9008.
You can try, firstly, by booting in stock recovery, formatting data, sometimes this may fix the bootloop issue.

Sorry, you are right. I am not good at firmware and all the related stuff. I've updated the post. I was confused about 'fastboot' and 'bootloader'. I meant bootloader was not unlocked. But about EDL - Redmi 6 has MediaTek SoC, but still it has something similar to EDL mode. Anyway, you showed me what I can try to do next. I will try to use preloader like here https://forum.xda-developers.com/t/...icked-redmi-note-9-merlin-hard-brick.4347025/
Thanks a lot!

Ok, I didn't check exactly the processor on Redmi 6, due to lack of time. Anyway, a MediaTek device is even easier to fix (in the paper). Qualcomm's devices have EDL (Emergency DownLoad) mode, and MTK has Download mode (apart from many more modes.)
You also, can follow this guide, with more visual insights https://forum.xda-developers.com/t/...india-6s-using-spflash-tool-for-free.4222027/ of course replace carefully the files from the ones that are for your device.
And this tool also can be useful, to take a complete backup, after to try a thing https://github.com/bkerler/mtkclient
Be advised, that, in any case you have to make a complete format, in SPFT only use the Download option.
Just as a side note, even your bootloader is locked, you always can enter to fastboot mode, the case is that is almost useless, specially in this situation, because a Xiaomi locked device can't be flashed through fastboot.
And to enter to fastboot mode, it's not the three buttons, you have within the various options, as ADB and commands are not available, you can enter manually, either, pressing the volume minus + PWR at same time, or pressing the volume minus button, at same time you connect your device to your PC.

OnePlus 8T Dead (Solved)

When I used the Fastboot Enhance tool to flash the payload.bin file, after the flash process finished I try to reboot but unfortunately it was dead.
No Fastboot, no EDL, no recovery, 3 buttons not working, power with up/down not working, when i connect to PC no sound that the pc recognize the phone "OP 8T", when I plug it into charger no info showing, Just black screen.
So it's working now, I'll explain everything here so it might help.
My device is OnePlus 8T DDR5 version
first, I understand what happened to me, I think the tool didn't recognize ram type automatically so it was flash DDR4 on a DDR5 device, so it made a hard brick
at this point, the idea is to connect 2 test points, and you can force your phone to enter to EDL mode, and we can do it in two ways:
1. Rootk1t giude, thax bro Rootk1t
- Removing the back panel by heating it.
- Unplugging battery
- Then use the EDL points on the motherboard to force the device to boot EDL.
- The device immediately will be recognised with just one tap on "enum" now.
- Plugging the battery again and attaching the back panel and rebooting
2. By using deep EDL cable, but not any edl cable, it must be a moded cable so it can be worked with the new security ...... this link will explain
Hydra Tool Gift Xiaomi, Huawei, Redmi Qualcomm EDL Mode New V2 Cable!! - GSM-Forum
Hydra Tool Gift Xiaomi, Huawei, Redmi Qualcomm EDL Mode New V2 Cable!! Hydra Tool New Type-C EDL cable Schematic With this cable you can reboot your
forum.gsmhosting.com
- So i use Hydra EDL Cble V2 , you can buy it from aliexpress
- Be ready and open your MSM tool
- Press the cable button before connecting
- Connect the cable to your phone when you still pressing the button
- Then connect the USB to your PC
- It will automatically put your phone in EDL mode
- Now your phone will show in the MSM tool screen so you can revive it.
Thanks to everyone who tried to help.
Special thanks to Rootk1t , semdoc

Seem like you flashed the wrong xml for the ram type. There is one for ddr4 and ddr5. If EDL is not working I'm afraid according to several post it's an unrecoverable brick...sorry mate!!!
However keep searching for a solution, you never know maybe a new method of recovery from this disaster may exist. I'll keep searching and if I find anything I'll post it here!
Also have you tried the 3 buttons connected from charger and disconnected? Usually for some reason my phone won't respond with the 3 buttons when connected to usb sometimes.
Also have you used the msm tool before?

Just one more thing, when you connect the phone to pc check your device manager to see if the PC reads the phone. If it does than its just a driver issue and reinstalling the qualcom driver for msm maybe needed.

I've found that sometimes I have to reinstall the Qualcomm drivers for EDL. So check that when you connect the phone to the PC in EDL mode there isn't an entry in Device Manager under Ports (COM & LPT)

I can't know which mode the phone is stuck on, because I have only a black screen, even the Power button with volume up / down not working,
do you think if I keep it for a couple of days the battery will drain and I can use MSM tool with press 2 volume buttons, it's the last thing i think about

I would open it up and remove the battery instead of waiting for days but that's also an option. It's not that hard to open, I opened mines to replace the usb port. I just held the back of the bottom corners of the phone over the stove until it was hot enough to soften the glue and used an old credit card and my thumb nail to open it. It maybe unrecoverable anyway so its worth a try.

It maybe unrecoverable anyway so its worth a try.

I can't know which mode the phone is stuck on, because I have only a black screen, even the Power button with volume up / down not working,
do you think if I keep it for a couple of days the battery will drain and I can use MSM tool with press 2 volume buttons, it's the last thing i think about

I've had a totally black screen at times in Qualcomm Crashdump Mode. To get out of it you can use Power+Vol up and then, when the phone buzzes, use the key combination for bootloader or MSM.

I tried a lot to press Volume Up + Power & Volume Down + Power & the 3 buttons, but with no response.
I can't feel any buzz, even I tried it when the phone connected to the PC, no sound come from PC prove that the phone is connected

Please keep us updated with any current queries or resolution as I'm very interested in the outcome.
Thank you!

Hello!
If waiting for battery to discharge will not help you, i suggest of:
- Removing the back panel by heating it.
- Unplugging battery
- Then using the EDL points on the motherboard to force the device to boot EDL.
-The device immediately will be recognised by just one tap on "enum" now.
- Plugging the battery again and attaching back panel and rebooting.

thanks my friend for your suggestion, yes I was thinking about this solution, but I keep it to be the last one, I think I will try this method at the weekend as I'm busy with work these days.
I'll tell you after I try this solution.
Thanks for your cooperation
