Can't get into recovery - Google Pixel 4 XL Questions & Answers

Hey all
I'm updating to May Updates using This Guide and then plan to update to June.
Problem is that I send 'adb reboot recovery' and the phone restarts, shows the start up screen, then the Google logo, then restarts without ever showing the android logo.
I can get into Fastboot mode and try to select recovery with the volume and power, but again, it boots to the google logo, then back to the unlock warning and boots to my lock screen, never going to the android logo.
Ideas?

Make sure you are using the latest adb/fastboot binaries (April, 2020). Flash the stock boot.img from the same guide. You will be unrooted but will be able to boot into System. Now read up on how to patch your own boot.img, it really is very simple. Personally I do not depend on, wait on, or use OTA's. The full image is available the first Monday of every month, and I extract/patch the boot.img from it. The whole operation including rooting takes just a few minutes. It's just one extra step. Once you get the pattern down it can be done very quickly, consistently and you're not depending on someone else's files. If you are bound and determined to use this method, you should seek out more guidance in the tutorial thread itself. Good luck. :good:

[Q] NEED HELP!!! moto x screen went black and is unresponsive

can somebody please help me? my screen just went black at work today and it does nothing at all now. if I hold the power button it vibrates once. if I hold power+volume down I get to recovery. I tried to reboot from there and I get the unlocked bootloader warning screen and from there it just goes to a black screen. so I get back to recovery and installed my back up and that didn't help at all. somebody please help me.
So the bootloader is unlocked, what else have you done to the phone?
You may need to reflash it with rsdlite.
OP you need to provide more details. are you getting the M logo? is it bootlooping? is the phone doing ANYTHING but getting in to recovery?
load the fastboot menu and use mfastboot to flash the system, boot and recovery images. you should be able to bring the phone back to life without losing data.

the only thing ive done to the phone is put xposed framework on it and gravity box. that was prob a month ago tho. this is the first prob ive had with the phone.
You may want to follow this guide to return the phone to stock firmware:

You could also try commenting out the line that overwrites user data so you don't lose your data.
Try plugging your phone into the original charger and then boot to recovery, from their try rebooting while still plugged in. If that doesn't work try this again but wipe just the caches and reboot while plugged in. I have had a screen go black before on other devices and plugging the original charger(car and most others didn't work) in and booting to recovery then rebooting would get it working again.
PS When you boot to recovery check your battery level.
well...I used the moto x toolkit and returned to stock using that. everything booted up. so far everything is looking good. lost all my data but that's not that big of a deal.

[Q] Boot loop after Google's update

My out of the box Nexus 6 is now stuck looping on and off at the Google boot screen after it tried to install the system update.
I've used the toolkit 1.9.8 to go back to stock. It goes thru the steps appearing to show OKAY and finished at each step. It never reboots the phone at the end. I try to force reboot after waiting for several minutes and it still boot loops. I try again the process again and sometimes it loops and a few times it actually starts up to the welcome screen. However, if I try to root or update recovery (using the toolkit), I get the boot looping again.
Did google bork my phone during a failed update? Is there anything else I can do to completely restore the phone? I've also downloaded the images on google and flashed---same boot loop.
Ultimately, my phone is now booting up to the welcome screen as expected and shows LRX21O. BUT, if I try to do anything (root or recovery), boot loop results again.
(I was able to unlock the phone and know about the usb debug and OEM unlock settings in dev menu, fyi).

XT1092 flashing (as in on screen flashing) recovery "no command" screen. Bricked?

XT1092 flashing (as in on screen flashing) recovery "no command" screen. Bricked?
Apparently I did something stupid. I had 5.1 which didn't OTA on its own to 6.0. So I thought it maybe had something to do with a past root i had and TWRP recovery. As solution I went and flashed a stock 5.1 rom in fastboot, which worked fine. Still no OTA though, and adb sideloading gave a status 7 error. Then I fastbooted the 6.0 stock rom, but that wouldn't boot (phone would hang in the white "unlocked bootloader" warning screen. I re-flashed 5.1 in fastboot.
Probably not a smart move, cause now I'm stuck in a bootloop to recovery mode where it's flashing the "no command" recovery screen for a fraction of a second, then black screen for 4 seconds, repeating over and over. I can trigger some orange log error by pressing VOL*UP like when you go to recovery mode, but it disappears in the bootloop. (it says qe 1/1 though, which suggests its rooted I read somewhere). So I can't do anything with it anymore. I read tons of threads here of which I found 2 with a similar problem:
http://forum.xda-developers.com/moto-x-2014/help/xt1092-flashing-command-boot-attempt-to-t3259287
http://forum.xda-developers.com/moto-x-2014/help/possibly-soft-bricked-moto-x-flashing-t3195103
It's the same problem I have now, and one of them says that "with some luck" he got into fastboot, but doesn't describe how.
Googling "flashing" related to recovery and/or "no command screen" in this context does'nt yield much result unfortunately.
For the love of god, I can't get it into fastboot mode anymore to do something/anything about it. I pressed, hold, tapped POWER and VOL*UP on countless ways, and it does a "deeper" reboot with appearance of the white unlocked bootloader screen, but it just keeps bootlooping.
How can I fix this? Did I brick it by fastboot flashing 6.0 and then fastboot flashing 5.1? Is it hard bricked and useless?
What do I have to flash when I manage to get in fastboot?
OK, I fixed it. Discovered it when the battery was drained. When the phone is OFF, holding POWER+VOL*UP+VOL*DOWN for 5 seconds and then releasing triggers the fastboot. Problem then is that you can't flash anything cause the battery is nerely depleted. So I let it charge in the bootloop for a bit and I found out I can hard reboot and get into fastboot by holding POWER+VOL*UP+VOL*DOWN for about 10 seconds and then releasing it. It probably turns off and then triggers the fastboot/bootloader mode.
Afraid of bricking it with OTA as I've downgraded to 5.1 from a (non-functioning) 6.0 I've manually flashed a 6.0 stock ROM in fastboot using this guide including mfastboot. So no sideloading or anything. Now it properly boots and I've got a stock 6.0.
Hopefully this helps someone in the future.

Boot-loop Help

Hey, sorry to bother everyone with another bootloop thread by I just can't for the life of me work out if I'm doing something wrong, or my device is more of a dud than usual.
So got the phone yesterday, did some ota updates ended up in a bootloop.
Now at this point my bootloader wasn't unlockable as I hadn't enabled it in developer settings.
By some miracle it managed to boot itself back into the OS after an hour of fiddling and i decided to enable the option in developer settings.
Now I've unlocked the boot loader and got all the flashing related fastboot commands working i've
Flashed a stock image using the miflash tool, seems to succeed but then on reb but once it's done i'm still in a boot loop!
I've been able to boot into twrp a few times (though most of the time I can't and am still in a bootloop)
Tried flashing a custom rom, but I always seem to be in a boot loop after attempting that.
Throughout the last few hours i've also managed to hit the os a couple of times but it seems very easy to accidently put it back in a bootloop.
If anyone has advice of something to try, that would be great.
(was trying stock image version 10.0.9.0, going to try and go back to stock Oreo)

Try some custom kernel, or patched boot img
I've found in 3 Mi A2 phones (mine, gf and family member) the bootloop is actually easy to overcome pretty quickly by waiting. I got the bootloop with all of them when they updated to two updates from what they came with no bootloader unlocked or flashing.
In each case I plugged the phone in, and left it rapidly turning on and off. Make sure to watch the phone, it will possibly come up with an error screen a couple of times so just press to continue trying to boot (also a glitched screen maybe that says fastboot with no options, press the volume control and the option to continue appears again). After a minute or two the phone will get to the normal charging screen, at that point the bootloop is fixed just hold power button until it starts.
Longest I had to wait was coming up to 2m, one time less than 30s.

Yeah, A2 have A/B partition and if update is faulty and the phone ends in bootloop, after a few failed boots, it will boot from other partition.

I think something along these lines is how i managed to get into the phone the first time and enable oem unlocking.
After a lot of playing around I was able to get the phone to boot by flashing the latest Oreo image (9.6.16)
After that tried going to a pie image again from fast-boot image (10.0.8) and once again ended up in a boot loop.
Lastly I flashed a fast-boot image of the latest ota (10.0.10) and managed to boot in.
So phone is at least all working now. Thanks for everyones help. Just hope the next ota doesn't bootloop the phone again.
@NotOverHere: When the phone finally does boot up, do you find it's stable and reboots are fine after that?

Pixel 4 XL won't boot anymore

Hello all,
I have been using my Pixel 4 XL for years, and all of a sudden it shut down, and now it keeps being stuck in a booting loop.
I get to Google's logo and the loading animation ... and then it turns black, and starts all over, in a loop.
I am able to access the bootloader and recovery mode.
I tried a complete wipe through recovery mode, didn't change anything.
I wanted to flash original images, but the bootloader is locked and I haven't found any way to unlock it without going through the phone settings (which doesn't boot anymore).
All fastboot flashing related commands fail stating my device is locked.
Would you have any suggestion ?
Anything I should try before considering my device is completely dead ?
Thanks in advance

Try sideloading an OTA image. You can do that with a locked bootloader.
Thanks Lughnasadh
I've tried multiple times, and the process fails randomly, at different percentages ...
The phone suddenly reboots and the laptop displays " adb: failed to read command: No error"
The weird thing is it doesn't reboot and can stay up for super long while on the bootloader.
With a locked bootloader the rescue OTA (full OTA image flashed via adb) is all you have. I would try a different data cable (A-to-C) first and then move to a different computer. Make sure the new PC is running the latest adb/fastboot binaries. This is why I unlock the bootloader on every Pixel in my family. Even though they will never root the phone, if the fit hits the shan you have many more options. BTW, I just traded in my son's P4XL and got $285 trade-in on a 6a. Net cost was less than $150. The deal just ended but will likely come back again. Same deal was offered earlier but included a pair of first-gen earbuds. Wish you luck on getting your old phone working. The P4XL is still my primary phone and is still working well.
