[Q] Used phone with no working HSDPA

Hi everyone,
I have following problem. I bought used phone with cm10.2.1 installed. After one day i realized problem with hsdpa connection. I put my sim card into another phone and it was ok.Then I started reading about issue and realize it could be problem with IMEI.
I check my IMEI and it seems to be ok. I went back to stock rom using Odin but problem is still there. I think I can connect to BTS, but in my phone mobile network type is Unknown:0.
I don't live in US so i don't have Us sim card, but my friends also in my country with AT&T phone could get access to hsdpa. In my country hsdpa is on UMTS 2100
Is there any way that I can check if my efs is ok? Could it be problem with hardware or rather software?
I found solution posted by umar4u, he attached file to NV writer to repair 3g and 4g issue. Is it save? Can I brick my phone or "only" mess in my efs?
Problem was solved writing NV items. I don't know if I can delete post, so please delete my post

SM-N900T cannot register canadian wind mobile network

I just bought the device on ebay with versions N900TUVUDNF9 baseband/bootloader/PDA/CSC.
Its rooted and sim unlocked.. It accepts Wind SIM Card. Finds WCDMA networks but cannot register on Network.
It works fine with Fido/Rogers/Bell at LTE. IMEI is the correct as indicated on the back of the phone.
I tried to rebuild NV using service menu without options success. Did no tried flashing modems yet.
Just wondering if anyone had similar problem?

Not getting 3G on my T999 on tmobile even though my other phones do.

So I recently noticed that my T999 was not getting any 3g H+ signals and was stuck on edge. The 3g was working in Taiwan (I lent it to my mom who has since upgraded) so I'm guessing it is some sort of authentication problem. Here is what I tried:
When I got back to the states I installed a few custom roms before noticing that the 3g wasn't working. It's possible that the qcn was fine in Taiwan and got corrupted after I came back though I have no way to check this.
I odin'd back to the latest stock rom and it was still stuck on edge.
installed custom stock rom for 4.1.2 so I could access the qualcom usb menu
The IMEI is fine but the IMEI SV is 12 which I don't know if it is correct. So I tried NV item reader writer and made a backup.
I then downloaded an NV items file which is supposed to fix 3g issues after an imei repair (which I did not do) from a thread in gsmhosting.com and wrote that into my device which did not work and is still stuck on edge.
tried same thing with QPST
tried to install SQS3 QCN generator but the author of that program has disabled the server so I can't install it and so cannot repair my IMEI
tested the nano sim card on an T mobile SGS vibrant and a Tmobile lumia 521. Both got 3g.
The nano sim is slightly thinner than a micro sim and the adapter does not compensate for thickness though I don't know if this really matters and I don't have an adapter that does compensate.
At this point I am almost contemplating buying a new IMEI number to see if that does anything. Any help is greatly appreciated.
