This is a longshot but since you dont have warranty you might give it a try.
Remove the back of the phone (there are tutorials on youtube for "disassembling ascend P6") and then remove the battery inside. Afterwards connect the phone to your ac charger, and retry to force update (power button while holding vol + and - buttons).
I really dont know if this works, but when i bricked my other huawei phone (u8800) where the battery was removable I managed to restore it using the aforementioned method..
Best of luck!

I had same problem last week, press volume up/down when phone boot. and keep pressing those buttons.
Dosnt work every time.. download firmware first and add it to external sd/dload folder..

i think i lost my stock recovery, i dont know why but i think that happened, but can anyone tell if the loss of the recovery will lead to the failure of force update? (in my case it won't start at all just stuck at logo)
if that happened i might try reflashing stock recovery with fastboot

ok i tried to flash stock recovery via fastboot, but the problem is my pc only reads my device when i connect it to it then hold power and vol - buttons till it reboots, then my pc reads it as an adb interface but it shows that it failed to install device drivers although i already installed the usb drivers and updated google usb drivers from android sdk, and everytime i try to flash recovery via adb (fastboot flash recovery recovery.img) it stuck with waiting for device
it seems its not recognized properly, am i hard bricked? :crying:

same problem with ascend mate
hi,
I have the same exact problem with my ascend mate mt1. its always stuck to ascend logo. when I press power button and hold cannot turn off. always turn on by itself. if I press volume down and power button, my computer can recognize it as fastboot. drivers can install no problem. can see the device when I type fastboot devices. when I try to install recovery with fastboot I always get that error says "not allowed". tried sd card update with press volume up + down no luck, also tried it with removing the battery but same. I think its hard bricked or something if you find a solution please let me know.
Thanks a lot !

i managed to get my pc to read my device properly (uninstalled usb drivers and reinstalled then voilla ) then flashed stock recovery via fastboot and the device booted just fine, however i cant connect to my network now although my phone sees it :crying:
anyway, make sure ur device is properly working with fastboot, just type fastboot devices in cmd and u should see some letters or numbers
also did u tried different recoveries it may be bad recovery file

Thanks
thanks for the fast reply. when I connected via fastboot its doesn't shows the serial numbers. its shows like question mark instead of serial number. I cannot find the stock recovery file , I only tried with twrp recovery and it gave the that message " Not allowed". I think I don't have driver issue but I will try though.

Can't boot into Recovery?! [SOLVED]

Right out of the RetailBox (with stockRom) I couldn't reboot into recovery using the "VolumeUp+Home+PowerButton" step...
Even now after installing a custom rom and twrp recovery I can't do the hardbutton action ("VolumeUp+Home+PowerButton") to get into the "recovery"
so whats the hiccup here? someone plz
thx

I just flashed a root... and then downloaded twrp through playstore and always rebooted with Newstart chosing reboot into recovery.... so it was fine till now..
now though, after installing IronRom .zip through twrp, it won't reboot anymore, it is stuck at the "Samsung Galaxy Tab S powered by android" starting screen.
Now I want to simply to the hardbutton reboot into recovery step, since i cant access it otherwise... but it doesn't react.
so whats the hiccup here?

I would also like to know this, I recently installed the PAC-MAN (unofficial) rom and things went weird.

So there is no way to get the HardButton way to work?
(My customRom already has multiple shutdown and restart option... thats how i've been operating.)
But once one is stuck somewhere and can't get to the system level (like boot loop or whatnot) it would be great to enter the recovery anyway... thx

You can enter recovery any time you want, you just need to do it right.
Hold POWER + HOME + VOL DOWN until the screen goes blank then immediately change to VOL UP whilst still holding the other buttons until recovery boots.

Holy Damn... thanks a lot!!!! that was really bugging me. I never found anything apart from just holding home+power+volumeup

I just tried this after trying other button combinations found on the web to try to get it to hard reset but nothing happens with my Tab S...it still stays stuck on the Samsung Galaxy Tab S startup screen. Any suggestions as to why that is?

Just signed in to say thanks for this, but for some reason I had to do it slightly differently. I was on stock 5.0.2 and trying to boot into recovery (Power+Volume UP+Home would start Samsung splash screens and then go black without ever booting into Recovery) so my solution was:
Shutdown Tab S, then hold down Power+Volume DOWN+Home (as though to get into Download mode) and then immediately after pressing that initially, I pressed Volume UP while still holding Power+Home.
Problem solved.

Someone please help me! I downloaded the apk above, chose "Boot into Recovery", gave it root, but it just took me to the "Downloading Do not turn off target!" screen & pressing Home + Power + Volume Down doesn't fix it! I'm using a Galaxy Tab S 10.5 SM-T800, stock Lollipop 5.0.2 and I used the combined TWRP & CF-Auto_root package on XDA to root it. Is all hope lost?

Hello prakash... Press power plus volume up for 10 seconds. It will automatically restart. As soon as you see it's restarting press volume down.. it will go into bootloader..
Flash proper recovery now from fastboot.. enjoy

Did you try force shutting down by pressing power down ?

even i am stuck in this mode, after the 3rd step from WinDriod Toolkit flashed supersu, returned to install Lineage OS from TWRP mode, was sucessful in that too however forgot to install GAPPS after that and proceeded further, phone asked that super su not installed and if i want to install one now, proceeded from there and the screen now shows a 'sad Teal colour smile',
Also the volume + power up worked and device restarted however vol + power down doesnt seem to work and device returns to the same state 'sad Teal colour smile'.

Phone bricked, no download mode, can't recover

So, as the title says. My phone decided to do a little update through OTA. All fine, all good.
However, during the update it suddenly switched off and rebooted. Then a nice screen popped up with the ominous message: "An error has occurred while updating the device software. Use smart switch to restore the firmware". Great!
So, hooked up the phone to that app, but it says unsupported device. The emergency recovery list also remains empty. Thus, a little Google-fu later and it seemed I could also do it with Odin. I know Odin, so no problem.
Downloaded the latest firmware with Frija, extracted, loaded into Odin. Then, I tried to enter download mode by holding vol up+down while plugging in the device. No dice, still the error message. Tried it countless times with different timings, but it simply will >not< enter download mode.
I cannot turn the phone off either. Anyone knows what to do? All stores are closed for the next 2 months due to Corona so I have no phone at the moment.

ohhhhh wait to open samsung store to fix

The buttom combos do no longer work. It seems there is no download mode or recovery anymore.
Anyway, the phone now completely died on me so I have to sent it in for repairs. It will no longer even charge or turn on anymore.

I'm having the same problem. Ugh. Can't get into recovery mode

To go into download mode at least on the n975u model you turn off the phone then hold volume up and down and insert the usb cable. It should boot into the download mode.

here is the solution
keep it running to empty out the battery
make sure its dead by powering up ur device
if u r sure its dead, keep pressing the combo and connect u r device to pc.
congrats,

And from there i think if you plug it in to odin you will find that the phone is still in download mode despite not showing the correct screen. Ive flashed firmware before with the triangle warning screen on instead of download mode, it works fine. So long as there is a blue indicator showing in odin then you can flash the device.

This is the actual answer. The error that op originally got is still in fact download mode.

My brother you saved my life thank you

To anyone coming across this thread, I had the same issue as OP. Bought a "new" Galaxy S10e SM-G970F which turned out to be SM-G970N. Everything worked except updates, but I managed to flash the latest version through ODIN.
A few months later, when I tried to flash a new version, the ODIN transfer stopped mid-way and the phone rebooted to a lightblue screen with korean letters and "Smart Switch" written in English. However, Smart Switch declared that the model is not supported for reinitialization.
I tried to reach download mode somehow, as the phone could not be turned off using a key combination or via PC at this state. What @GeeAyeZee and @pcriz said is absolutely correct, THIS SCREEN IS INDEED CONSIDERED DOWNLOAD MODE.
I persisted with ODIN, trying to flash the new version 2-3 more times (rebooting the phone and PC between attempts) until eventually the process completed! Phone is unbricked. Hope this helps someone.
