[Q] Change hardware key mapping fastboot mode - Nexus 5 Q&A, Help & Troubleshooting

Hi guys!
Here what I wanna do:
My POWER Button is broken, I have somehow managed to bind the VOLUME_DOWN to lock/unlock the phone when it's on.
However I want to figure a way to turn on the phone (when it's off) only by using the charger (not an external support like the PC with adb).
So I wonder If I can enter in the fastboot mode (by plugging the charger and pressing VOLUME_DOWN button) and then press the VOLUME_UP button to boot directly on the system.
Is there a way to do this ?
For instance mapping the VOLUME_UP button to run the cmd "fastboot reboot" ?
Thanks

PLease any idea ?
Thanks

Hi,
I updated the stock kernel a few days ago so the phone automatically boots when its plugged into a charger.
Is it something like this you're after?
What kernel are you using at the moment?

Hi Mike and thank you for your answer.
It is definitely somethinf I wanna have!
My kernel is : HAMMERHEAD-HAMMERHEAD: Android 6.0.1 - Build: M4B30Z
Thanks a lot

ok,
My updated kernel can be downloaded here - https://drive.google.com/open?id=1m11geKa39h3oplTAJeFSySd6E79CjaQS
The original/backup can be found here - https://drive.google.com/open?id=1njEwbcpwNWAW7WLUwn6FS6PvGY7iZdmN
just flash it as per usual via fastboot:
fastboot flash boot image-new.img
fastboot reboot
Flash the original/backup if you have any problems..
*** I hold no responsibilty if anything goes wrong etc etc... but it seems to work fine on mine with the same build...
Let me know how you get on...
Mike

Ok I've the very same problem, I can only turn on the phone by entering in bootloader (hold VOLUME- and plug USB), and using fastboot (fastboot reboot), but I need a PC obviously.
I'm wondering the same thing as amazingmif, remapping one of VOLUME BUTTONS to POWER.
I prefer a bootloader mod and not to rely on kernels (but thanks mikep99)
Could someone help us?
Thanks!

Hi KeyofBlues,
I have found a temporary fix that requires only the USB charger.
Enter to the fastboot mode with your PC and run the command : fastboot oem off-mode-charge 0
Now if your phone is off, it can be turned on only by plugging the USB!!!
Hope it will help!!

Volume button fault - Any other ways to go to bootloader?

Hello all,
my sensation's volume rocker is faulty. By pressing volume down and power on, it will not boot into boot loader thus cannot enter recovery.
I know i can use software to boot into it boot loader but what if I am getting bootloops and unable to boot into rom?
Any ADB commands to make the phone boot into bootloader straight?
I am planning to flash the factory RUU and go claim my warranty after i get my Galaxy nexus..

Possibly not unless your timing is amazing!
Are you stuck in bootloops now or is this hypothetical?
Please, tell if your volumne rocker is so broken that it cant even turn up/turn down volumne during normal use of phone?
If it's ok, thet I suggest method of booting into recovery which I use (and i had problems to boot before - thought it's vol. rocker):
1. press volume down button and hold it!
2. press power button for 2-3 seconds and then release, still holding the volumne down
3. phone boots into recovery after few seconds.
Hope it might help you.

Implying he can't control volume in a bootloop, I seriously hope this guy uses 4EXT touch, or else he needs to replace the rocker.
Can you flash zips from USB fastboot?

I understood that he can't enter recovery due to some volume button fault. When you stuck in bootloop only thing you can do is pull out the battery, no keys/buttons are usable - tested myself :/

not really hypothetical.. in fact i experienced it earlier..
my volume up/down seems to have a mind of his own and at times i will enter "safe mode"
thereafter it will auto reboot unless i am quick enough to do a factory wipe under settings... it will still boot into safe mode but wont auto reboot.
so after knocking a few times on the volume rocker, i am able to boot into normal mode but the volume rocker isnt working. Pressing it once, will cause to decrease the volume and switch to silent mode.

lol this sux man..
I dunno if HTC singapore will honor the warranty cause this is a hardware defect and nothing to do with any rom or unlock..
Even in bootloader mode, press up will cause it to go down or at times up. pressing down may or may not respond.
If you in a boot loop adb should see it for split couple seconds so with the phone connected I would keep trying to do adb reboot recovery

That's what I thought but it didn't happen when I tried it on mine.
From Fastboot, adb commands also work, provided vol - works while powering on. This sucks dude, sorry.

If you have CWM recovery installed (im not sure about other recoverys), you can connect your phone to your computer when it's off and you will have access to a limited adb provided by CWM. You can then use the command "adb reboot recovery" or "adb reboot bootloader" or whatever to do what you need to do.
Wipe all then cant boot into bootloader
Hi, i'm really sorry to bring back this post,
your fear had become my nightmare in reality.
The volume button was somehow (either physically spoil or is not capture click)
during booting process.
I have completely forgotten about it, and do complete wipe
(select wipe all except sdcard in touch recovery).
So, now the phone is completely clean (without rom)
and i'm unable to trigger bootloader/recovery via pwr/vol down button.
I have try take out battery,leave it for 10min and try press
all those button without casing/rocker;
press & hold vol down, den plug in battery;
and press both vol up & down then only pwr button.
The phone now (i assume) boot normally,
stop at HTC logo because there is no rom inside
(just like normal pc boot pass bios but cant find OS).
ironically, i live at singapore too... haha...
---------- Post added at 10:58 PM ---------- Previous post was at 10:51 PM ----------
I read somewhere that the person use pin to press the button really hard
and it manage to go into bootloader
(but I cant find back that post now)
Searching in forum recommend me to peel off the
volume button cover n use pin to press on it directly
(which I do not dare )
So now I sent it to repair shop,
hopefully that person using either g-box or gmbox
(flash box start with G) and can push RUU inside.
God bless me.
p/s : Sorry I should post in Q&A...
Get the phone off. Pull the battery and re-insert. Open fastboot
Fastboot reboot-bootloader
And if you want to flash a ruu directly:
Fastboot erase cache
Fastboot oem rebootRUU
And then flash the ruu

Hi, can you tell me exactly step by step how to open fastboot?
pull out the battery, press vol down (??), reinsert?
fastboot devices go no response after booted and halt at htc logo.
Thank you very much.
Have you tried finding where the rocker lines up with the buttons on the phone, and just used the buttons without the back attached?

Need help with HTC sensation, i think he's bricked?

K got this HTC from a friend of me, was working before, had it rooted and fixed with custom rom
It was S-on on v1.27
k now gonna try to explain what's going wrong:
When i shut down the phone, put battery out, back in, connect to usb, i get the phone recognized by ADB (my HTC phone)
when i type adb reboot-bootloader, device responds and boots into fastboot mode
when i use vul up i get Fastboot usb on screen
from this point i can't get any further, device doesnt respond from any button action except for vol up.
Device is not recongized in windows now (windows 8 64bit) got the famous error 43
So in ADB everything is fine, but in fastboot nothing is working/responding
when i pull battery out, then put it back in, i can succesfully boot with volup en power, then i get everything running (custom rom from before) but it says safe mode
Any ideas what i can do to get this thing back on it's feet?
regards,
Robin

In bootloader(fastboot mode) no buttons will works except vol up,down and power..
If you want to flash a custom rom then
First goto bootloader
Now enter to recovery by using vol down and then power button to ok.
Place a Rom.zip in sdcard format cache/dalvik , all partition except sd and then flash rom..

problem was that none of the button's where responsive, i found the cause of this, volume buttons are damaged (the strip inside was broken)
So now i have a new problem much wurse i think
only power button works, so i did a complete reinstall with ruu, booted up fine, but always in safe mode for some strange reason,
Now after shutdown, i can't get the phone on anymore, only goes to Hboot, and there is nothing responsive, non eof the buttons work, can't use vol buttons because they are broken.
Adb is not responding either, only getting HTC Android USB device in my device list....
I think the phone is ready for trash? :S

so when you are in hboot screen try this command
fastboot reboot (in the hboot screen should say fastboot usb)

since you are dealing with a hardware problem then yes
but try this
boot normally(even on safe mode)
connect it to pc and type
adb reboot bootloader
it will take you directly into fastboot mode
then type fastboot reboot
see how it goes and check volume button from there(to confirm the hardware issue)
otherwise repeat the procedure but instead of fastboot reboot run the ruu.exe again

Manually power it off by pressing power for 12+ seconds
Then try to enter fastboot mode (Vol down + Power)
If your phone is S-ON you can't really brick it by flashing boot.img
Just try to enter the bootloader and tick fastboot.

This same thing happened to me. I left it plugged in for a while, then pressed and held power for about 15 seconds. Then I pressed and held volume down and then pressed power. It came back to the fastboot screen. Hopefully yours will as well.

xt1032 BootLoop (Android starting..) can't enter recovery or bootloader.

Hi everyone im stuck on the resurection of my device (moto g 2013 8GB updated to 5.1 with [5.1 GPE 1 click] from This forum.
I've tried everything or almost for now, cant get it out of that loop.
*Battery pulling.
*hard buttons combinations.
*fastboot and ADB. (not in fastboot mode so.. And as i did flash de 1click before the loop USB Dbgn isn't enabled)
*i think i've tried every toolkit on this forum.
*Raped google search for over a week trying every posible method-
*Only thing left is to take it to church for a blessing. but im not a believer D:
ADD: i've rooted with a "boot.img" from this forum i think it was a 2015 file.
before this i had not 1 issue with the phone. just unlockd the bootloader a few days ago and updated to 5.1 from 5.0.2 becouse of a wifi issue (unknow mac adress) i had to reboot it like 10 times until it appeared again (original mac adress from device, still wrote it down i have it somewhere.)
I think this would be my first post on this forum and it took me over a week to do it becouse this (asking you-comunity) is my last resource.
PS: i had it going betwen 5.0.2 and 5.1 like 4 times to try solving the wifi issue.. only thing it got me was the "line" on the screen like if it where a problem with vertical sync. (i think you are all very familiar with that issue after downgrading the kernel i think.)
the phone just turns it self on everytime. (everytime)
i was able to boot into recovery before the last flash touching the place were the hardware volume button goes (with a neddle) untill it didnt workd anymore and i send it to a store to repair the volume rockers. still no recovery or bootloader boot.
my pc (laptop with 7-32bit recognices it as xt1032. and the one with xp as MTP.)
I've installed every posible thing that i found to bring it back to life even the android sdk full every pkg from 5.0.2 to 5.1 and extras, Motorola drivers and ADB. tried online searching automated from windows and listing it from a folder with the google one. tried adding the hardware manualy and have every ADB thing that i found on device mng but everyone is wit a yellow triangle. (No USB Debuging enabled so why bother anymore.)
I think that's about it.
You seem to be making things massively over-complicated.

i m sorry for my english, isnt my native lang. And for making it over complicated.
i cant enter fastboot mode or give any order to the phone trough fastboot on a console.
I have installed a TWRP touch, just cant acces it. dont know if it is the hardware button (Vol -) or what.
so it dosnt show up on fastboot devices nor adb devices.
am i not understanding something ?

If the volume rocker is not broken, then you should be able to enter fastboot mode. Hold power button until phone turns off completely.

did that, tried pulling the battery off and holding the keys (down and power or just vol down) and starting it. no way it goes into bootloader or recovery. When i do any of those things the phone just powers back up it self and boots into system or tries to, and get stuck in bootloop.
Im gonna try a gtag cable or something like that tomorrow from a friend. would it work to send it to bootloader or recovr?

i think it's not repaired properly, or the last time i flashed it fastboot might have send a command like "fastboot normalboot" or something like that. Would that be stoping me from entering recovery mode or fastboot?

How can I get my Galaxy Note 20 Ultra out of stuck at 'entering fastboot mode'?
Hold down power and volume down until it reboots back to recovery. I got stuck there last week and that's what worked for me.

Switch off the device. Then hold volume up and down buttons and insert the USB cable plugged to PC. You will get to download/odin mode

Download mode is different from fatboot mode, I can enter, and works ok download mode. However, fastboot does not, it gets stuck in entering fastboot mode and no fastboot command works
I got same issue here, I've tried rooting via TWRP and after data wipe and "reboot to recovery" it got stuck in same thing and doesn't move at all, if I hold power and vol down it just boots the device which i dont want since i need to flash magisk as a last step. if anyone encountered this or knows how to fix it i'd be helpful

The ROM is already bricked, it says in recovery when i try to factory reset the following error:,, can t mount. /system (structure needs cleaning)
Even with,, apply up. with adb,, doesn t work, it just doesn t get detected on my computer when i checked with adb tools.
! The only thing that works is that I can access my sd card and apply a update from sd card but I don t know where to get the update file. (I ll edit if it works to flash stock rom from,, apply update from sd card,, )
Anybody got some ideas or should i burn my motherboard and replace it?
sorry for bad english
Honestly plug device into PC.
Power off device
hold all 3 side buttons. Volume up and down and power/bixby.
Should usually work.
After in fast boot you must press a button Volume button to find via odin.

I already did that, unplugged the battery, reconnected it after 1min, connected my phone to the computer and pressed all 3 side buttons, still doesn t work. I guess the download mode is deleted or something..
Volume up & down, no side key, then connect to PC. Works for me. Connect to PC first does not work for me.

It wouldn't be deleted as it's a safety protocol if the device has a bad update and freaks out.
Maybe try to person above method.
Normally I can enter download mode with any of these methods if you cannot I'd suggest trying to get the device replaced due to software malfunction

Samsung phones use a tool called Odin to flash firmware. If you're flashing custom firmware firmware you'll need to have your bootloader unlocked.
I got mine into download mode just now. It's a Galaxy A13 .. Like stated above, try to hold all three buttons down and connect to USB. I had to let go before it showed the battery charge icon. From off. If not from off try from charging. I think that's what I did just now. Plug the usb -> let it show the charging icon (from powered off!) -> hold all three buttons, let it power on, let go. DONE.
just follow this video it helped me a lot to unlock my boot loader
