Does it everytime when you power up the phone? I sometimes had this issues, but then i turned the device off and on again and everything was fine

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.

[Q] Can't enter download mode

Hey guys.A while back I wanted to install adfree so I rooted my e975.Sometime in August I updated the android to 4.4.2 and I think the phone got unrooted.But SuperSU was still installed and I wanted it removed.So I tried a factory reset (settings->backup&reset->factory reset data) but SuperSU was still there afterwards.
Then I thought I should flash the kdz.So I tried to get my phone into download mode (volume buttons pressed and then connect to pc) but the screen shows nothing.I also tried going into recovery (volume down+power button) but that doesn't appear to work either.
Does anyone have any idea what's wrong with my phone?Everything else is working fine so maybe I'm doing something wrong.
Sorry if something doesn't make sense, English isn't my first language.

No one has any ideas?
I think this may be a hardware problem so I should find a way to hide the fact that the phone got rooted in case I need to sent it back.Is there any way to remove SuperSU without flashing the kdz?

Thanks for helping me brijen95.I just tried what you said and volume down+power key doesn't seem to work.The screen just stays black so I can't do a hard reset.Vol+ and connect to pc doesn't work either.The phone just starts charging after a few seconds.I also just reinstalled the drivers but it didn't change anything.

I had a hard time getting into download mode recently as well. What ended up working for me was holding the volume keys for about 10 seconds, then while still holding the buttons, plugging the usb cable into the phone.

No that didn't work either .
Is there any way to remove SuperSU?Keep in mind that my phone is not rooted anymore.
Edit: Well I just found out that the phone is entering download mode but not showing anything on the screen.I managed to flash the kdz with no issues.

Also try press and hold power, home and volume up and down together to power of and then press and hold power, home and volume up to get to recovery where you can data factory reset and wipe cache which is what I did and mine did boot up eventually.

you had a different problem.
yours worked fine before and you couldnt get into recovery mode.
Mine doesnt boot after installing new ROM,
but recovery and odin mode stil work.
I made factory reset and wiped cash already before. Doesnt work.

I just wanted to say thank you. This also worked for me just now (i had flashed stock 6.02 back in as i was having issues seeing 5Ghz networks with my current image). It did take a while to boot, and had me thinking the procedure would not work...good thing you pointed out to wait patiently! :good:

BootLoop post Viper4Android module on Magisk with Lineage 15/Oreo

Lineage /Oreo was installed thru TWRP 3.xxx, running fine but unhappy , no Viper4Android , so I installed it as a module on Magisk,
after installing the driver, was ask to reboot as directed, but went into bootloop , stuck on a boot loop " Set Warranty Bit : kernel " top left corner and Samsung Galaxy Note 3 on screen ; I tried Vol Up +Home+ power combo and all other combi I could think but no luck , Odin wont recognize my phone, tried Samsung 300k tool with no luck, I fell like a newbie after using so many ROMs on all of my devices, I google how to get back to download mode but no luck, I need help to make my Samsung note 3 work again, PLEASE. THANKS.

Hi,
I have same phone but I'm running Resurrection Remix 6 which is based on LineageOS 15.1 and I'm able to use the Viper module through Magisk 16.3 without any problems. No bootloops, no nothing.
I never would have guessed that a sound mod could brick the device to the point that the buttons no longer function. Hopefully other users will chime in and help you fix it.
Best of luck.
EDIT: Try taking the battery out to force it to shut down and then try the recovery/download mode technique again. Sometimes, it'll end up in a bootloop and the buttons will be become unresponsive. I know it may seem a bit strange, but that scenario is entirely possible given the age of the device.

You may have to try a USB jig to get into download mode.

The jig that I bought didnt do anything so I make my own, I can go to download mode now, installed this ROM/firmware N900TUVUCNB4_N900TTMBCNB4_N900TUVUCNB4_HOME.tar.md5 succesfully but wont go pass beyond the tmobile logo, tried a few more firmware and lately this N900TUVUFOL1 and also , am stuck to Tmobile logo, anybody knows which firmware would likely bring my note 3 back to life, thanks in advance.:

Try this:
Uncheck everything in Odin except f reset time. Flash the latest ROM again. When you see the word "reset" in the status WIndow, remove the USB cable from the phone, remove the battery, replace battery, boot into recovery mode using buttons, factory wipe, and reboot.

After "reset" status, I did remove cable, remove batt and boot up to recovery, the blue light lit up as if its going to recovery mode , android logo showed up but phone boot up to normal but not pass beyond tmobile logo, so I did CF-root via odin , but still not booting to recovery.

Try flashing the entire ROM in AP.

I manage to restore my Note 3 to TMobile Android 5 using repair firmware , it looks like I wipe out the partition ,My phone runs like new, am just wondering why I cant go to Download mode with button combinations of Volume -/Home/power , tried to install twrp via Odin, it says PASS but Vol +/Home/Power wont lead me to bootloader, did tried CWM , it will boot up but before I could start using it, it will reboot to normal and I could not go back to bootloader with button combo Vol+/Home/Power........HELP...

Download mode is volume down+home+power.
To flash TWRP with Odin, try this:
Open Odin and only check f reset time. Flash TWRP. When you see the word reset in the Odin status window, remove the USB cable from the phone, remove the battery, replace battery, press home + volume up + power.

N900TUVUFOB6_N900TTMBFOB6_TMB and N900 PIT - are the files am using after screwing up my partition( I dont know how I did that ), this Note 3 is running like a hot knife on a butter BUT the only bug I notice is Volume Up + Home + Power ( recovery) NOR Volume Down + Home + Power (download ) does not work, I can only go to download mode using a USB JIG and no other way. I can flash TWRP via Odin with Auto-reboot not ticked , so I could remove cable, battery , hoping to get me to recovery mode but I couldnt. Did I miss a step?I need help.

Recovery-mode only, is there any hope?

[SOLVED] Download mode can't be removed, I had to try all dat long but I finally could boot into it.
Hi,
So... I had a working Samsung Galaxy S9 (SM-G960F/DS) running Lineage OS yesterday. I noticed something wrong related to the mobile network in my country (FR) and decided to flash the correct stock firmware matching the country code XEF before doing a full LOS reinstall.
Fast-forward 20hrs of download, I perform the flash operation this morning using heimdall(1) and reboot.
Now, the phone bootloops. I can't get into download mode as usual, and the only thing that is available is the stock recovery mode that allows:
apply update from adb
apply update from sdcard
wipe data
wipe cache
mount /system
view logs
run graphics test
I have a working all-countries firmware archive that contains the one that was working previously (minus the mobile network problem). But since I don't have download-mode anymore I can't install it. I tried adb sideload (which is available via the "apply update from adb" option), wipe data/cache to no avail.
Is that hard-brick? Did you ever experience a similar situation? I think there's no way out of this but any advice would be appreciated.
Thanks again!

You should be able to get into Download Mode (Vol Down & Bixby & Power)
Keep trying, try keeping hold of the button combo until after the phone reboots twice hopefully the second time into download mode
Download mode has nothing to do with firmware or recovery that has been flashed, and if you can enter recovery mode, it doesn't sound like a hardware problem either
And use a Windows machine & ODIN 3.13.1 to flash stock

Unfortunately it doesn't seem to work, i tried many tiimes and I usually can do that very easily. It seems flashing the corrupted images wiped it out.

Impossible as it is not part of the firmware, nor can be touched by firmware, it is part of the hardware (Think BIOS vs OS)
You can even 100% wipe all internal storage clean so there is no OS at all and download mode will still work fine
Keep trying

Okay I guess it's possible that the download mode is still there but I can't reach it.
I've been trying hundreds of times every combination I can think of (including Home + Vol Down + Power that used to work).
Any alternative way to trigger the download mode ?

How are you trying Home? There is no physical home button
The button combo is Vol Down & Bixby & Power from a powered off state
Keep a hold of all 3 until it hits the Warning screen, then hit Vol Up to enter Download mode
No other way to access it that I know of, USB Jig hasn't worked since a few models back
Have you tried factory resetting from inside recovery? Unless you used CSC during the stock firmware flash, that could be a reason for the bootloop

Maybe the issue is with the Volume Down button, does it work inside of recovery for navigating the menu ?
What happens when you try entering Download mode? It just tries to boot as if you didn't press anything?
Only other thing is to hold Volume Down & Bixby, then connect the USB cable to power it on (instead of using the power button)

The volume down button works perfectly in the recovery menu.
When I try entering download mode normally while device is powered down, the phone never turns on.
When I try to hold the buttons during the interval of the boot loop, it goes to recovery (yes, even with volume down, not volume up).
The other technique you mentioned also went to recovery.

BINGO! I kept trying. Did this all day literally hundreds of times.
And it just worked.
I didn't change the way I do it, I think there was some nasty timing going on with the boot loop.
Anyways... lesson learnt: download mode is indeed hardcoded. What a day!
Thanks for being so helpful!

Good stuff, yea well whatever it was hopefully it's sorted now, use ODIN this time
