I too have this issue. This isn't a bug, it's intentional. Google is only letting the tool be used on screens that come straight from them. You're better off (1) supporting right to repair legislature and (2) making this issue more public. Apple had a similar case where when enough people spoke up, they reversed their anti right to repair practices. Maybe tweet @ifixit or something? They're a big name!

Well in that case it's just Google trying too hard to stop independent and diy repair

if this is a bug with android: fastboot oem udfps get-cal-url returns an invalid url on some screens/fingerprint scanners

this is either because its reading the data from the screen wrong (unlikely)

or because the calibration file does not exist on google servers (more likely)

Same issue here, got a screen replacement and can't use the fingerprint sensor and calibration tool is not working.

The calibration software is installing correctly for me, but still doesn't fix the fingerprint. I always have the error "Failure to read image. Try again." when trying to register a finger for the fingerprints in Android settings / security / Fingerprints.

It's non genuine screen or incorrect display for the region of your device.

Do you have some evidence for that? The repair shop insisted the part was genuine (they said there is no non-genuine pixel 6 screens available)... And this is the only comment where I've read mention of the region of the device (my device was brought direct from Google in the UK if that makes any difference).

The comment doesn't seem consistent with the 404s (unless the filename is some sort of hash derived from phone region and hardware id) either...

From issue 218761008 on 04/09/2022: The result from fastboot oem udfps get-cal-url is tied to the display. I got a replacement display, installed that into my pixel 6 and installed the fingerprint sensor from my old display in the new display. I noticed that the fingerprint sensor wasn't working and when trying to calibrate it, got the same error as everybody else here ("Couldn't find unique software for this device"). I then installed my damaged display again and ran the tool again and then I could download the .signed.cal file using the above command. Tried to install that file with my new display (using the fastboot command line tool) but it gave me an error that the display serial number doesn't match up with the serial number from the cal file. So this is definitely a display issue and shouldn't be fixed by factory resets, Android updates, etc. My guess is that only genuine google displays have a .signed.cal file hosted on the storage.googleapis.com/ domain.

Maybe someone from Google can confirm or deny this?

I don't have access to a windows machine :(

Can I ask you what files the https://pixelrepair.withgoogle.com/udfps website downloaded for your screen and where your replacement screen came from? And can you confirm you were getting the "Couldn't find the unique calibration software for this device" error when you tried to use the above website before installing the driver?

Won't change a thing. I am able to install the calibration software, but it still doesn't fix anything and still cannot use the fingerprint to register fingers.

pr...@gmail.compr...@gmail.com #106Sep 30, 2022 09:57PM I'd try this as it has helped others. Posted by a user on ifixit:

I've solved this for my Pixel 6 Pro, so here's a quick guide... or links to other people's solutions, really.

First, you need to go here, and download the Google USB driver: https://developer.android.com /studio /run /win-usb (remove spaces, they truncated the URL if I post it normally); just get the Zip file and extract it. The Google USB Driver is located in \usb_driver, I found the file named android_winusb.inf.

CRITICAL: do not use Device Manager to install the file. Locate the .inf file within the extracted folder (mine was titled android_winusb.inf), then right click and select Install. If the Install option is not listed (Win11 doesn't show it at first), click More Options at the bottom of the menu.

Then, go here (MUST use Chrome browser) and follow instructions: https://pixelrepair.withgoogle.com/udfps

Thank you, this worked for me.

Im now a year without fingerprint scanner because of this issue, i think it should be an s2 level severity, this is critical functionality for some banking and finance apps now

so i kinda figured IG

do these

After enabling usb debugging

Power off and enter BOOTLOADER and not FAST BOOT

(hold power and volume down ) even commands via adb gets u in bootloader but in there (bootloader) you cant download that "software" it will

get you "Couldn't find the unique calibration software for this device "

use VOLUME buttons to ENTER into RECOVERY MODE then press POWER OFF and VOL UP SIMULTANEOUSLY (same time it should enter to recovery mode menu)

(there it says Android recovery)

from there navigate to ENTER FASTBOOT (this is a differnet menu)

here it says FASTBOOTD (idk whts that stands for)

SO HERE COMES THE CATCH IN THE WEBSITE ( https://pixelrepair.withgoogle.com/udfps ) you can Download the software for Your device but i cannot INSTALL the Software and it wont download no matter how many time u try to hit retry

do hit me up if it works for Pixel 6

ive had this issue since December 2021, thats right, my pixel pro 6 went for a screen repair in december 2021 to official Google repair in Poland, came back have had this issue since then. Shame on Google, breaking fingerprint sensor during an OFFICIAL REPAIR. Get your act together.

NOT a FIX (I guess)

Well my fingerpirnt sensor started working randomly after pressing the sensor area couple times and going into recovery menu from there i choose Apply update from adb (did nothing) and came back to recovery mode waited for like 5 mins and restarted (this is the random stuff i did)

is it normal ? coz i have been facing this sensor prblm for december 2022

Another Your device's current software version:TQ2A.230505.002 is newer than this repair tool has.
