wrote: Tue Dec 16, 2025 8:04 amHey i am not getting the updates like its December 16 and the update is released on 2 December, but I have not received it yet, I have not got the update, and also I want to go back to my original IMEI and undo the CPID. Can you help me
you cannot undo cpid unfortunately
Okay, so what are the solutions? I have seen an IMEI on my SIM tray. Can I go back to that? The only issue is that I have checked on the serial number, which is linked to the IMEI, and it does not match my current device's serial number. In the cpid process, are the devs also changing the serial number ??? and I want to do 2 things: my device is an battery-infected device, so I want to check by changing the imei back, I can claim free repair, and the 2nd thing, this device is not getting updated, the December update is out, and i can't update it, so give me some solution tnx

you can manually flash deceber build (it will erase data)
this guide is for restring original imei only. if you have misused it & now want to restore original again.. then still in future if you will receive any new update yur imei will become 0.
battery issues are not related to cpid.
& yeah unfortunately fixing imei affects to serial number as well.. as the tool is using same devinfo.img for imei repairing purposes.
hey tnx and also few more things like i have checked online that the imei on my sim try belong to specific green google pixel 6a and dash is its serial number if i change my current imei to the one on sim tray then the serial num will be same as last or chnage to a new one or the one that is linked to that imei ? and last thing canu make a video or can u share me any contact method so i can ask u in case of any issue while doing this.

check drivers/connectivity
It worked for me once around a month ago when an update made my 6 pro IMEI null. But when it happened again and i did the same things again, it made my IMEI restored but this time, my sim is showing "No service". What's the solution???
