[Q] nvfalsh problem. can't enter apx mode

I'm currently using Topogigi ICS 28G.(using new bootloader)
it can boot the rom, enter cwm normally.
but the problem is it can't enter apx mode when I connect it to pc.
after I press vol+ and vol- while connecting it to pc, the screen flash for one second and nothing happen.
the pc not detecting the phone.
wish to try cm10 and need to go back to oldbootloader by nvflash.
anyone has the same problem and solution for it ?
or are there any way to change bootloader without using nvflash ?
btw, I'm sure the cable and pc is not the culprit.
I try to enter apx mode using my friend o2x and it done flawlessly. but not my o2x.:crying:

Go to the recovery, wipe data/Factory reset.
Then reboot. switch it off. Take out the battery. Press the vol- and vol+ button, then put the USB cable.
It should work.

Solution found !

Hello there,
I have the same or similar problem, where my P7 won't boot at all, won't go into recovery mode or fast boot mode.
Only thing it does when i have it connected on the charger and try to boot it is flash the LED 4 times red color, then once green, it keeps doing that and that's all it does. i tried what you said and it won't work or boot, it does the same thing.
Your help would be appreciated.

power off your phone by pressing power botton for 10 seconds
after that connect it to pc by usb cable
press "power botton" and "Vol-"
does the phone boot into fastboot mode?

No, it doesn't, however when i connect it to the PC, the PC emits the USB sound (that you've plugged something in) but it doesn't identify or recognize anything.

then there's no way to flash anything to it, the only way is by fastboot and adb commands

That means it's probably a hardware issue? the motherboard might be fried?

i think yes, sorry for you

P9 Hard Bricked - No recovery, no fastboot

Hi,
First i'm sorry for my bad english.
I've a P9, and i tried to update to Nougat. But something went wrong, and now, i can't boot my phone, no recovery no fastboot. When i plug it on my pc, my phone is recognize as "USB SER". How to unbricked ?

Hold volume down + power for 15 seconds, hold it even longer to try to get into fastboot mode. Was the battery low? Maybe you need to charge the phone up.

My phone is charged.
I tried your solution, but didn't work..

It only boots to fastboot from adb shell or if i plug it in my computer and hold vol down + power if i dont plug it in it will not boot into fastboot.

I don't have access to fastboot or recovery. I have black screen, when i try all combinations. When it's plugged, it's only recognized as " USB SER "

Hold Vol Down while inserting a USB cable connected to your computer, assuming you have one.

Yes, i have a computer. I tried to insert usb cable with vol down, but my phone is always recognized as USB SER

Hey mate, did you find a solution, same thing happened to me ... the only thing I get from the phone is "USB SER" ... never unlocked, rooted or flashed my phone. Could be a hardware failure?

Fastboot working ? (Switch off your phone, plug usb cable in it, then plug usb cable in your pc)

ADB method not correct...
Turn off phone...
wait 8-10 second...
plug usb cable to pc...
Hold Vol-DOWN + Power and plug your cable...
then youll boot in fastboot (ADB)
maybe explain what happened to end in a bricked device

Hi all,
I've updated my Galaxy A71 to the latest update included with AP patched by Magisk Manager..

Except for the device status in the bottom "unlocked" for me.
was this caused by the update or I've screwed something ?!!
any help would be appreciated , thank yall.

could you please try fastboot command? with fastboot binary?

the same thing happens to me and whatever i choose in the bootloader screen doesnt make a difference

Not that I'm aware of sorry ... You are connecting cable to a powered on PC or laptop? Holding down both volume up and volume down whilst connecting cable ?

Also they need to hold the power button

On the newer samsung phones you need to power off your phone hold down volume up and volume down and insert your charging cable in your phone make sure the cable is inserted in a pc or a charger.
