Do you mean PM9200 have hardware differences ? Or maybe frequencies locked in nv-items? Can compare Sprint, Verizon and PM9110 boards.

Can anybody give some advices?

HI, again
I have tried to perform unlock using this instruction
https://forum.xda-developers.com/mot...t1056-t2825155


but nv-items


# 08378
# 08035
# 08322


Can not be read or written.


Also I've read that they could be in read-only.


2 questions:
- Is it possible to make this nv-items readable and writeable again?
- will it help to make HSDPA, HSDPA+, 4G-LTE working on this phone?


P.S. Boards from PM091 and PM092 are absolutely the same. (I can share photos)
I am 100% sure both hardwares support all bands and protocols, but bands are locked by SW

Hello Nick,

Is it Desire 626, right? Please give more info about your actual firmware, and if it was reflashed - what was the original fw. I may try it on my phone.

it was sprint 0pm92 with android 6
Not sure what was the stock fw
1. if I will downgrade fw will it remove readonly from nv-items?
2. do you mean if i have phone with the lowest firmware version which was never updated it will allow to write nvitems?
3. or you have another way to unlock 3g and 4g bands?

have also virgin, boost versions of 0pm92 MIDs

Nick,

We read your posts, but we don't know how to help you, if Sprint phone does not support 3g/some frequencies, why do you blame XTC2 for this? We never had "Activate 3g support on Sprint phones" option.
You can try custom radios yourself, if you need spare radio images - just let me know, but obviously we can't even test it, as we don't have USA frequencies here in Europe, I'm sorry.

Of course it have 3G. And 4G too. It is just do not work after unlock. Seems like blocked 3G bands. Hardwares of 0pm91 and 0pm92 are absolutely the same. It is some kind of software limitations, I will try. Won't I brick 0pm92 board with 0pm91 or 0pm93 radios?

Yes, give me radios
