Question Pixel 7 Pro stuck on "usb serial device" with no screen - Google Pixel 7 Pro

Hey all,
after trying to flash images from a private build
[
1) REPO: repo init -u https://android.googlesource.com/platform/manifest -b android-13.0.0_r11
2) LUNCH: aosp_cheetah-userdebug
3) fastboot flashall -w for the out directory
]
the Pixel was stuck on a boot loop, showing the google screen but nothing more.
after battery drained, tried to put it on fastboot mode, unsucessfully
right now, the device is in this state, with black screen showing nothing.

Does someone know what tools are needed to save the device and guide to do it?
and second question - something in the process I described above is wrong about the flashing that caused it to fail?

Wow...where to begin...?!
I completely don't know to what end you were attempting to get to or how you were trying to get there, but looking at such an unconventional method of flashing and unconventional "private build" (so I assume not the full factory images Google publishes on their dev page), I wouldn't be surprised if you didn't permanently brick your device -- especially considering the outcome is a weird "USB Serial Device" and black screen/no fastboot mode...
But what I suggest is powering on using the button combination (I believe it is PWR & VOL+Down), sometimes it takes 1-2+ minutes holding it down.
I would suggest correcting the driver, but I'm unsure if that will lead anywhere if you cannot get into fastboot mode and/or the screen stays black. But, if you think it will help; download the Google USB Drivers (can be found HERE), unzip it, uninstall (and MOST IMPORTANTLY tick the box that says delete the driver software if it pops up) the "USB Serial Device", Scan for New Hardware, if the new driver does not identify as "Android Bootloader Interface" then -- right click the new driver -- click update driver -- and either Browse to the folder where you unzipped the Google USB Drivers or manually "Let Me Pick from available drivers" and manually select the .inf file to install the driver as. That should correct your driver issue, though I don't know how helpful it will be without the screen or being able to get into fastboot mode...
And, if you don't want to risk breaking your P7P, I would suggest from now on sticking with traditional methods of flashing (platform tools or recovery mode) and Google Full Factory Images or established ROMs....
Or maybe research considerably more in the unconventional method you are trying to attempt...
Good luck to you, seems you will need it...

it's basically flashing from here

I have tried the combinations to fastboot, but unsuccessfully, all I see is black screen.
thanks for reply.

Stuck big time. Help requested (Nexus S)

Hi all,
Well my adventure started last night when I went to return my Nexus S to stock. I did so and it worked well. Then I tried to re-root the device.
After doing so, it now will not boot past the google boot screen (with the unlock icon). It just sits there, even after battery pulls and additional attempts to start up. I can reboot into recovery (fastboot) as shown on the attached images. After hours of reading, it seems I need to flash CWM recovery.img to get the phone to boot. Ok, not a problem. So I installed the android sdk, google and samsung phone drivers and my phone is recognized in device manager.
When I go to flash the recovery.img via fastboot, it just sits there on "waiting on device" and ever goes anywhere. I also have a message on the bottom of the Nexus screen that says "FASTBOOT STATUS - FAILInvalid Command"
I'm at a point where googling is doing no good. Please help.
How can I get my phone to boot? How can I successfully flash the recovery image so I can go forward with root and be done with it?
Thanks.

First step is get fastboot to recognize the phone.
Until the command fastboot devices brings up your serial number you can't flash. Your issue is either you don't got the fastboot driver installed ( does not install correctly by itself on windows 7 64bit) Or your in the wrong directory in fastboot. Or both.
Quides are on the forum how to do everything.

Ok, how does one go about doing this on Win7x64?
Quides are on the forum? No idea what that means.
The forum is the place you're on right now. Read the stickies/how to's or just use the search feature.

Believe me, I've done that. Hours and hours worth.
Anyone care to help since apparently this information is so easy to locate? Fastboot simply isn't communicating with my phone and it will not boot past the google boot screen.
After many hours of trying, I figured it out. It had to do with the PDA net drivers. Basically, my phone would not boot up, preventing me from finishing the PDA net install. It kept hanging on "Installing PDA net to your phone" because, well, it couldn't install to my phone (since it was in fast boot mode).
I kept clicking on OK on the dialogue box and it would roll back, uninstalling the PDA net drivers. This was why fast boot could not communicate via cmd.
How I worked around this was by NOT clicking ok, hence not uninstalling the drivers.
It was an epiphany. And a pain in the arse.
So, if you have a similar issue, don't click ok on the dialogue. Leave it in limbo and work your command line magic!

Question ROG phone 5s not recognized in fastboot mode, but ADB works... Windows driver issue?

Hi All,
I bought a ROG phone 5s (ZS676KS) direct from ASUS and I've been trying to root it all week. The firmware version is WW_18.1220.2111.160.
So far, I have been able to unlock the bootloader using Asus' app. My phone displays the unlocked bootloader warning on every boot.
I can't make fastboot work... the "adb reboot bootloader" command does work. I can also boot using the power + volume up button. But the "fastboot devices" command always comes up empty.
I found two possible reasons why fastboot doesn't work. So far I failed to fix either one.
First, the "OEM unlocking" option is missing in my developer options menu. I have the "USB debugging" option checked off. But many of the guides I read online say to allow OEM unlocking and I can't do that. But I've also seen people say that it doesn't matter. So, I don't know if this is a real problem. I can't find any reference to this problem except in Samsung phones. I tried the recommended fix but it didn't work.
Second, something's wrong with the fastboot driver on my computer. When get my phone into fastboot mode and plug it into the computer, device manager shows a device called "ASUS_I005D" with an orange caution icon on it. The error message in the properties menu says "The drivers for this device are not installed. (code 28)". This is probably the real problem.

Windows isn't finding a driver with its online driver search. I spent a few hours playing with Windows drivers to no avail. But maybe I missed something. I did find "ASUS_Android_USB_drivers_for_Windows_20150212" online and it didn't help.
I have tried different wires and USB ports and I'm using the side port of the phone instead of the bottom (although I tried the bottom port too). I tried another computer and that didn't work. But this was before I realized what was happening with windows drivers so I didn't check the device manager. I'm away from home now so I just have access to the one computer for now.
Does anyone know where I can find the correct driver? Or is there another approach I haven't considered? I hope there's nothing fundamentally wrong with the phone. I kind of just bought it without explicitly verifying, assuming the 5s is rootable since the 5 is...
Thanks Everybody,
Success is disgusted by some people, and will not share any files for free in the future.
It's not your device but likely Win 10 playing games with you. First completely uninstall the device driver to clean things up. Reboot your pc into Safe Mode. Plug in your phone from the side connector with a good data capable USB cable. From Device Manager choose "Add Legacy Hardware" from the menu and point the location to where you have saved the latest official Android USB drivers and install. Reboot Windows normally. If things have gone well, you should be able to both ADB & Fastboot into your device.
What a relief.
I am now able to flash my patched boot.img.
Thanks to both of you. I'm off to the races...
For me I just get a Ubuntu iso, boot your computer off a USB stick, install adb and fastboot via apt, and boom, no crappy drivers needed

Question Made A Mess - ROG 5 CN Fastboot Loop

Was trying to flash my CN ROM to the WW ROM.
Forgot to turn on USB Debugging in Developer Tools.
Couldn't get it work using HunterTik's guide.
Ran flashall_ATF from windows explorer.
Command prompt flashed on screen then vanished.
Tried running flashall_ATF in an elevated command prompt.
It failed but has apparently wiped the ROM. Device is now stuck in boot loop to fastboot.
Whatever option I choose reboots the device back to fastboot.
Windows can see the device but adb devices returns List of Devices Attached is blank.
How do I recover the phone from here?
Found this thread Rog phone 5 stucked on fastboot
Ran this command: fastboot -v flash all WW_ZS673KS_18.0830.2101.75_M2.13.24.14.1-ASUS_1.1.63_Phone-user.raw
Received these lines of text & now device boots to splash screen, gets stuck there, reboots a few times then sends me back to fastboot.
Still can't access recovery mode

Device is now back in a fastboot loop with no access to any options but power off & restart.
Your phone is broken
Buy a new phone and don't try to mess with it next time
Flash back to CN and try again.
or, get a dump of the official firmware, then sent boot / recovery / super over fastboot manually.

also, you might want to try 9008 rescue. it seems like whatever you're trying to do wiped / repart the partitions. that's why the BL is confused.
also, if you're on win11, some driver related **** can mess things up causing flashing fail.

9008 rescue is the direction I was headed & you're right. Although, on reflection, the partitions were already deleted prior to running the 'fastboot -v flash all xx.raw' command. Not sure how, since that command was the only thing I did which resulted in something happening.

adb cant find 4g Adas Mirror, any help pls.

Hi!
This is my first post here, I hope I won't make many mistakes and troubles...
A friend of mine asked me to help him with his car Android based mirror.
The mirror is a "4G Adas Mirror" which is now stucked on the boot screen/logo.
Android version on the device is 8.1.
I've tried to reset through the hard reset button, without success.
I tried to connect the device on my PC to try to get access with adb, no success.
Adb cant see the device, the device list is empty.
When I check in the device manager on my PC I can see under "Portable Devices" installed,
with the name "MTP USB Device".
I also downloaded several drivers but can't install them, not for my device.
And now I'm out of ideas.
If somebody have any idea what could I still try to bring back the device into live, I would really appreciate.
Thank you.
Btw.:
My PC is running win10 x64 Pro
You're probably stuck with only the MTP interface (and not a composite device with MTP and ADB) but it might be worthwhile to double check.
Is the MTP interface active? Can you see any files in Windows File Explorer?
You can check with UsbView.exe to see if there is only one interface, the MTP.
The next step is to try various buttons on boot to see if you can get to recovery, fastboot or ROM bootloader.
Thanks for the fast replay, I cant access the device throug any file manager, as you mentioned, I checked with UsbView.exe already, just to be sure.
The MTP is active.
I've tried many many times the switch combination with the reset button, to try to get into any recovery or whatever cmd line mode, but without success.
The device hase only two buttons:
1. Power button
2. Reset button

Well, there's many ways to skin a cat.
If you open it up there could be a UART with a rooted hardware console.
There could be pushbuttons or test points to get into some other mode.
Good photos will tell us.
So, here we are....
the mirror crashed until I tried to open it.
However, if somebody is interested to hack and poke around this device, I'm familiar to open the device,
make schematics, pictures and try to hack into the device to try to make it alive again.
If somebody is willing to be a part to this pls. let me know and let's get started.
Open it up and take photos.
I'm trying and searching for a way how to open it but not fully crack the mirror, which is actually also a monitor...
I hope I will open the device soo and be back...

that's not a lot of info to go by. what did you do prior to getting this screen? since when has this screen been showing? is it rooted? did you do low level stuff with it, and if so, did you do it through a computer or on the phone directly?
the first thing you would want to do is to check if you can enter recovery mode (stock will do if you don't have an aftermarket) and see if you can do something with that, like, say; factory reset.
the next thing you could try is to first backup your flash, and I mean from sector 0 to EOF, and a second backup per partition, then flash a stock rom you could get online.
I WOULD preffer to just diagnose the problem and fix it non-destructively but phones and their OSes are not built to accomodate repair beyond changing the screen/batery and resetting/flasing the ROM
P.S. throw in the chipset type while you're at it I.E. MTK or QLM
Thank you for your response, bro! This phone is a second-hand phone. When I received it, it only had the factory mode. I flashed Android 11 through the website flash.android.com, but every time I boot up the phone, the screen will display for a few seconds before entering the system. I searched online and it seems that the phone is still in factory mode and needs to be activated to normal mode, but I haven't found a way to switch to normal mode.
1. Enable ADB ( AKA USB Debugging ) on phone
2. Connect computer and phone via USB-cable
3. On computer run ADB command
Code:
adb reboot

well, taht just sounds like the ROM didn't come with a boot animation/logo so I suggest if you want one you can well... there's not much you can do without tripping tamper triggers I.E. install rootkit & modify system partition (can't be done post pie) or unpack system image, insert the animation/logo and repack, but then you have an orange state device and that's not much better than that factory logo, or you lock it without image verification enabled and hope that something doesn't rely on it
android isn't built to be moded, so you have to mod it before building an hoo boy is that a wild ride
P.S. on second read, the ROM might be in eng mode instead of userdebug or user
you could check it by either terminal emulator, issueing the command `getprop` and search for build variant or do so through adb
