i have cheap 6750 phone which does not read some nfc tags.
i am thinking it could be software issue due to nvram or nvdata partition got somehow damaged during firmware updates or many factory restores.
anybody can help how to use maui meta app nfc section to fix nfc issues?
i was also reading this thread on restoring nvram and nvdata with partition collected from working phone.

https://www.hovatek.com/forum/thread-23412.html

if i follow these instructions and flash nvram nvdata images from other working phone to mine, do i risk to brick my phone?

have you tried reading the tags on a different phone first before concluding the problem is from your phone?


"if i follow these instructions and flash nvram nvdata images from other working phone to mine, do i risk to brick my phone?"
No, but you must ensure the other phone has the exact same build number as your phone

Thank you!
Yes tried other tags and found for example friend's phone reads NFC tag aka SmartTouch on Candy washer with no problems.
However on my phone Candy app loops on the same tag as if it tried read something over and over.
What is confusing "NFC TagInfo by NXP" app shows identical results on both phones in full scan.
Phone has NFC chip by Broadcom and Candy washer has STM chip.

My concern aside bricking phone are also contactless payment apps tap&pay, I think such apps use information stored in nvdata or nvram.
If I overwrite nvram and nvdata might I run into other problems?

You can backup your phone's nvram and nvdata + preloader using miracle box @ https://www.hovatek.com/forum/thread-13347.html then test the nvram and nvdata backedup from a different phone, this way you'll be safe.

If this started after you installed an OTA then you should consider flashing the stock rom of your previous build number.
What is your phone model BTW? Does it use Android Beam?
