i have a problem with my boot up,
my phones has an bootloop, but i can start it up by booting up in bootloader and flash boot.img manually then it boots up 1 time, if i shut it down and restart it, it has a bootloop again so before every boot up i have to reflash the boot.img can anyone help me?
Are u sure that u typed :
Fastboot flash boot boot.img

Hi everyone...
I recently installed the latest cm9 on my ARC.
I want to install cm7.2 again, but I can't get it to work.
This is what I do:
1) fastboot the image file (fastboot.exe boot boot.img)
2) Install the zip
3) Clear data/cache
But it just hangs at the CM 7.2 logo.
If I install CM9 again, everything work fine.
Any ideas?
fastboot flash boot boot.img
from the ARC

Exactly!
With fastboot boot command, you simply make the kernel boot once.
Fastboot flash boot will do it for you!

Thanks guys... I suspected it had something to do with the flashboot command. I'll try it out ASAP.
EDIT: It's working now, thank you
Hey guys, I think i screwed up big time. I have just received my Htc one M8 from rogers (with no bloatware on it .. weird lol ) And i wanted to root it in order to use titanium back up.
So i followed a guide to root the phone everything went well execpt that now my phone boots straight into philz custom recovery....
When i was entering the fastboot commands to flash the recovery to the phone i made a mistake i wrote :
fastboot flash boot recovery.img
instead of
fastboot flash boot recovery recovery.img
....
So my guess is that i have overwritten the boot.img of the phone with the custom recovery which is bad... now i can't use the phone...
Is there a way to flash the stock boot image back? of to restore the phone like it was brand new?
Thanks for you help
Reflash the both with the correct commands !!!
Fastboot flash recovery recovery.img

Yeah this is what i wanted to do but i couldn't find a boot.img. I did find it eventually. here it is in case anyone needs it
Straight, just saying.
The boot.img is always in the rom....Most roms contain the stock boot.img. or check my backup collection and download the stock rom. It has the stock boot.img inside
Thanks a lot.
Hey guys I think i have a problem
I was trying to flash v4a, and realized that I needed to downgrade twrp from RC2 to RC1. My phone had been rooted by SU.
I proceeded to do the flash and then flashed the v4a mod but now my phone can't get out of TWRP. When I click reboot, it boots into the recovery mode.
Any ideas on how to solve this? I cannot use my phone now
Use fastboot to flash stock boot on both slots
fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
Fastboot boot twrp.img
Then flash twrp and all should be fine

Just wanted to chime in so people in the future can see that this worked, at least for me on my Pixel 2 XL.
hey, I tried this method to boot back into system but lost TWRP recovery... any way to install TWRP without flashing boot.img again? or which boot.img should I be flashing back to slot A and B.. i extracted the boot.img from factory images but i lose TWRP recovery
I just want to check somethings before going through root procedures
1/If I pressed volume down before unlocking bootloader to not losing data is this affects the whole process?
2/After flashing patched boot from another build by mistake, flashing original boot.img solve the problem right?
3/after root if I used magisk module and it caused bootloop what can I do?flash the original boot again?
Thanks in advance
1 Dunno
2 Yes. If you bootloop just get into fastboot and push the command to boot original boot.img
3 Yes same as 2.
Don't flash it, only boot with patched boot image. Command: fastboot boot patched_boot.img
So I just switched to a Pixel 3 XL yesterday from an OG Pixel XL and I've having some issues with the kernel.
I build my own kernel with a couple of patches and I don't know how to flash it through fastboot on this device. On my OG XL I could just do "fastboot flash kernel" with the image I had built, but on my 3 XL that command returns "Not allowed to flash (kernel)" when I run it. Do I really have to make a flashable zip now?
Secondly, when I just try to boot the kernel, it takes quite a while to boot and then my touch screen doesn't work once it boots. The buttons all work so the device isn't frozen, but I can't unlock it or touch anything. I thought it might be one of my patches (even though they have nothing to do with the touchscreen) so I completely removed the kernel source from my PC, re-downloaded and rebuilt it (as per this page: https://source.android.com/setup/build/building-kernels) and even with the resulting bone stock kernel, my touch screen does not accept inputs when I boot the kernel through fastboot.
I suggest you use FK manager from Playstore to flash the kernel you made. It can flash any zip file. I would flash stock back and then try your kernel once you are in full stock. just to make sure it's not problem left over from your a possiblly corrupt installation of other thing.

Not really an answer to my question. The OG Pixels can flash the way I want to do it and I want to know if this has changed for the Pixel 3 and whether or not I can make fastboot allow it. The whole point is to avoid the step of making a flashable zip, since I never had to before.
If you've unlocked the bootloader and used the correct command to flash the boot image to the active slot or both slots, then all should be well!
Good luck.
I think the command you're looking for is "fastboot flash boot boot.img" where boot.img will be the name of your kernel

I think the command for flashing a kernel is fastboot flash kernel (name of kernel).img. fastboot flash boot boot.img flashes the boot.img to the active slot. fastboot flash boot boot.img --slot all flashes the boot.img to slots A and B.

Please explain.
I think since the Pixel 2 the kernel has been included in the boot.img. Correct me if I'm wrong though

You are correct to flash the stock kernel you flash the boot.img to both slots: fastboot flash boot boot img --slot all

Ok, but I'm not flashing a complete boot image. I want to just flash the kernel by itself, which you could do on the original Pixels by typing "fastboot flash kernel" and I'm pretty sure the kernel was part of the boot image on those phones too.
