Apologies if this is a repost, I couldn't find anything that was specifically related. My Nexus 6 updated to 6.0.1 recently, worked fine. Next day, battery had run out of charge, plugged it in and it would only boot up to the bootloader menu. It won't boot up fully, or won't boot up recovery mode either. In the bootloader logs I get the following;
'failed to validate boot image: ret=-1'
If you try to run recovery mode;
'failed to validate recovery image: ret=-1'
I've tried to flash a stock recovery image and a stock boot image but to no success. Anyone have any solutions? Bootloader is unlocked and device is not and has not been rooted.
Edit - Nexus 6 fully working again! For whatever reason, I took out the SIM card tray and it worked first time. Thank you for all the responses!!

Have you tried booting directly to your recovery? Try the following command without the quotes and replace "xxx.img" with the name of your custom recovery: "fastboot boot xxx.img". example.. fastboot boot twrp.img

It says it's sending 'recovery', writing 'recovery' and then finished. I restarted bootloader after it had done and tried to enter recovery mode but the same thing happened. It does say now in bootloader logs 'invalid boot image header'.
Then try booting to recovery.

May you find some solutions here
Okay, I took the SIM tray out, as I read that on the thread suggested, and I've been able to flash all the images necessary. Just booting up now, I'll let you guys know if it works! Thank you to everyone for the responses!!
This makes no sense as to why it works but it did just fix my spare nexus 6 that wouldn't turn on after sitting in a drawer for a week

Hey,
I attempted installing Android Revolution on my HTC One - but it rebooted the phone for some strange reason during the install - i am now stuck on the HTC white boot screen - it was looping but i cleared the cache. I can still enter fastboot mode but don't know how to get the phone back to a state where i can actually get past the boot screen.
The phone is a 3 UK one.
Any help would be greatly appreciated.
Zack.

To be honest i am pretty new at this. I can access the recovery menu and enable fastboot and also access Clockworkmod T. Unsure where i am going from here.
Currently as it stands the phone will not get past the white HTC loading screen.
Right, i have an original ROM dump (system.img, boot.img, recovery.img) - I presume this would be the best way forward? I issued the following:
fastboot flash recovery recovery.img OK
fastboot flash boot boot.img OK
fastboot flash system system.img > load_file: could not allocate 1946156032 bytes, error: cannot load system.img, not enough space.
Can anyone help me? My phone is just stuck on the HTC boot screen
Hi all,
Any help I can get would be greatly appreciated. I have a Sprint HTC One M7 that was previously rooted. Currently it is relocked with S-On, but at some point an OTA update was downloaded and now my phone keeps restarting itself and boots to this "android is upgrading..." screen. It keeps doing this loop over and over. It restarts itself, and then goes to this "android is upgrading..." I've spent hours in the forum this afternoon and I've tried numerous things and nothing seems to be working. Everything I've tried keeps giving me errors. At this point I would simply like to go back to the stock ROM and have a working phone. Can anyone help?
FYI...
I've tried using the .exe method from an RUU, but that isn't working because when it reboots to bootloader at the very beginning of the process my phone boots to android and I get the "android is upgrading..." message.
I've tried extracting the rom.zip and sideloading it, but I can't sideload because installing the TWRP.img recovery fails every time.
I've tried a factory reset and that fails. Again, I get the "android is upgrading..." loop.
Basically, everything I've done to run RUU fails because my phone reboots to android instead of rebooting to the bootloader, and everything I've tried to work around that problem fails.
I'm currently running 6.23.651.7 and I'm trying to flash 6.23.651.10.
Again, any help would be massively appreciated. I'm desperate...

You can't flash a rom.zip extracted frin a ruu.exe using TWRP, it must be flashed using fastboot with the phone booted in RUU mode.

Holding power and volume down doesn't work? This should get you in bootloader mode. If your phone can't boot to a stable bootloader there is nothing you can do. Once in bootloader there are many options to unbrick your phone.

I first tried flashing the rom.zip using fastboot, but when the phone is supposed to display the HTC logo screen my phone just reboots and goes back to the "android is upgrading..." page.
I can get into bootloader when I hold power and volume down, but I haven't been able to successfully do anything from there. I tried flashing TWRP so that I could attempt to sideload a ROM, but I got an error when flashing TWRP.img.

What is the error when flashing twrp?
fastboot oem rebootRUU doesnt work?
Is your bootloader still relocked? If it is, you can't flash custom recovery. The only thing you can do is run RUU in that state

Well, I was just going to try and do this again, but now my PC can't even find it when I run "fastboot devices." I have the SDK and ADB driver installed, so I don't know why it can't find it all of a sudden.
I can't install the RUU by running the .exe, because when I do and it gets to the "waiting for bootloader..." screen my phone reboots and loads android and goes to the "android is upgrading" screen. So I need to flash the RUU via fastboot, but now my PC isn't recognizing my device in CMD...
Okay... so I finally got adb and fastboot working again. When I run "fastboot oem rebootRUU" the phone reboots to Android and goes to the "android is upgrading..." screen.
Update: So... I was able to successfully use adb and fastboot to unlock my HTC One again. I then tried to flash a custom recovery via fastboot, but I kept getting "FAILED (remote: signature verify fail)". I tried flashing TWRP, CWM, and stock HTC recovery and got the same failed message for each one. I'm just trying to find a way to break this stupid boot loop... HELP!
Update: So, my phone even restarts itself when I boot into safe mode... not good. Can anyone help me out?
I tried to install twrp on my OP3T but everytime i write "fastboot flash recovery trwp.img" it says "error: cannot load 'twrp.img'"
When I type "adb devices" my phone doesn't show up
I unlocked the bootloader
I activated USB debugging
I checked the OEM thing
I have put the twrp.img in the same Minimal ADB and Fastboot folder
What could it be?
Install correct driveres or use another usb port. Device have to be adressed via "fastboot devices" or "adb devices".
It's probably a typing error ..Rename the twrp in whatever you want and then type " fastboot flash recovery " whatever you want".img
Rename file
Did you rename the file? You need to rename it before flashing.
IT WORKED
Everytime I was putting the phone into bootloader mode, the phone was already plugged in. Then I tried to put the phone to bootloader mode and THEN plugging it in my pc... and it worked ^^

The last parameter has to be the EXACT filename, that you are flashing, which is the TWRP image. It has to be in the same folder as your command prompt is or you need to include the path to the twrp file.
Try the last TWRP release, should work!
Would like to express that I am also having the exact same issue. Any version of TWRP simply fails to load and stays on the TWRP logo.
I am on OxygenOS 3.5.3.
Anybody know a solution? I am currently running with no recovery now and I am quite worried.

After installing the twrp and then you type ... Fastboot boot twrp.img. Probably you are stuck on twrp splash screen...
Try to boot manually.to twrp by pressing power button and volume down button...Then you should be able to boot on twrp....

Did you try to fastboot TWRP after flashing it?
What I mean is, after you enter the command "fastboot flash recovery twrp.img", proceed with "fastboot boot twrp.img" and it will boot. Doing this you prevent Oxygen OS from overwriting TWRP. You should be able to boot normally after doing that.
Don't be worried and try to boot into recovery as described, that should work, if it doesn't I wonder if you flashed the right version of TWRP.
Try and let us know.

I'm having some difficulty getting past this step.
I've unlocked bootloader, enabled oem unlock and enabled usb debugging. I've added the PATH where my twrp.img file is located.
Whenever I input fastboot flash recovery twrp.img, it says error: cannot load twrp.img: no such file or directory.
I see the file in the correct location so i'm not sure what i'm doing wrong here.
Any ideas?

Reinstall your adb + fastboot drivers
Hello, I wanted to install TWRP and ROOT my phone. I flashed TWRP using adb terminal. But when I tried to boot into TWRP it was stuck on "Your device is booting now..". Then if I held the power button for few secs it rebooted normally. So I tried to google it and I found adb command that reboots to recovery
Code:
adb reboot recovery
. When I executed the command it rebooted to the "Your device is booting now.." screen and it stays like this forever. No button combination works to reboot the phone if i hold power button it reboots shows honor logo and then shows the "Your device is booting now.." screen. I waited for the battery to drain and then i put the phone on charger and when I tried to boot it, it was the same. Now when I try to reboot the phone it shows ultra low baterry symbol and then boots to "Your device..." screen.

Which twrp you flashed? Check the correct twrp in my signature for honor 5C repository.

Did you try all method to going in fastboot.by adb fastboot command or by pressing vol- and power button?
Hi guys, thanks for your replies.
I somehow managed to boot to fastboot after waiting for the battery to go out completely. From there I used the following commands in ADB from the extract of a stock update.img :
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
And it worked ! The first boot was veeery long and now it's normal again.
Now my last concern is that I still have bootloader unlocked. As I wish to come back to factory state and avoid the warning message on boot, do you guys think it's safe to re-lock bootloader ?
I'm kind of scared to try anything else and screw the whole thing now
Thanks again for your support

Can you please explain to me how did you managed to boot into fastboot? I tried waiting for the battery to drain completely. Now I can't fully charge my phone. When i connect it with charger. It starts normally charging like it would with 0% battery then after a few moments the honor logo shows up and then the screen "Your device.." shows. When I try vol- and powerbutton it vibrates and shows the red lightbolt then after few moments it boots the same way into the your device screen. When I connect it to the pc it doesn't react. I don't even hear the classic windows beep sound.

Now you have firmware zip, extract it amd you will get few files. Use dload method as given in my signature and you are good to go.
Else use Huawei extractor and browse to update.app you just got in above downloaded zip. You will get boot, recovery, system img you need.
I downloaded some firmware versions and extracted them. I don't know which is for my device. So I tried one of them. I flashed boot.img and recovery.img but I din't flashed the system.img, becouse it was too big. When I tried to reboot the phone it was the same. The fastboot was no longer accessible. I put the phone into servis but they didn't fixed it. it's the same but I can enter erecovery

I've on an older version of Android. I've never had a problem using TWRP on other phones but due to the lack of having it on my Pixel 4XL, I've just never had it.
I haven't upgraded in ages, I see we have a working TWRP now. I tried to flash it via Magik and I think I flashed the wrong one.
My phones stuck in a boot loop mode and IF I can get to the screen that says "fastboot mode", I cant do anything with it.
"adb devices" returns nothing so I cant even attempt to flash the correct recovery.
Help!

When you get to the screen that says "fastboot mode", do "fastboot devices", not "adb devices". If that works, flash the boot image with "fastboot flash boot boot.img". Make sure the boot.img matches what you had on the phone before breaking it. Either the stock boot.img or magisk patched boot image should work, but you'll loose root with the stock boot.img.
It is best to boot TWRP without installing it. "fastboot boot twrp.img".
Hey.
Yeah check "fastboot devices". If you get something on terminal, use Google flash tool to reflash the original firmware, this will repair any damaged/corrupted file.
If you don't get anything your phone is very likely bricked. You can still try the emergency mode but I believe it won't work. In this case there is still a way to recover your phone, and it's using the EDL mode(which is contain in every phone that has a Qualcomm Chipset). From there you can force flash firmware and boot image.
Tell me how it goes
OK I got TWRP working.
Phones updated to September 2021, turned out I was still on March 2021! Anyway, all updated, rooted etc!
Thanks very much folks!
