Subject: Play Integrity Failure and Device Not Certified (Nothing Phone 1 - Spacewar)
Subject 2: FINGERPRINT NOT WORKING AFTER FORMAT)
Device Information:
Model: Nothing Phone (1)
Firmware: Nothing OS (Spacewar-V3.2-260206-1016)
Root Status: [NOT ROOTED/NEVER ROOTED]
BOOTLOADER STATUS [LOCKED]
The Issue:
AFTER A CLEAN FORMAT DEVICE /RESET DEVICE. Iam experiencing FINGERPRINT ERROR:
1) REGISTRATION ERRO:
Details: WHEN TRY TO REGISTER THE FINGERPRINT IT NOT PROCEED FURTHER LIKE STUCK ON PUT YOU THUMB TO START.
IMP: FINGERPRINT LIGHT WHEN TOUCH WHIOE REGISTERING
DUE TO WHICH I FACE THIS ISSUE MENTIONED BELOW


I am experiencing a “Device is not certified” error in the Google Play Store. When checking Play Integrity, I am failing MEET_DEVICE_INTEGRITY. This is preventing me from using banking apps like Paytm and other secure applications.
What I have tried so far:
GSF ID Registration: I have manually registered my Google Service Framework ID on the Google registration page.
Clear Cache: Cleared data/cache for Google Play Store and Play Services.
Hardware Maintenance: I recently performed a firmware flash and had to troubleshoot the “Persist” partition and Fingerprint sensor (SPI entry failure).
Recovery: I have used EDL mode and QFIL to restore system integrity, but the Play Store status remains “Not Certified.”
Question:
Has anyone successfully restored Play Integrity on the Phone (1) after a deep system flash? Are there specific “Spacewar” firmware steps I am missing to ensure the bootloader/system state is seen as valid by Google?
Any help from the community would be greatly appreciated!
