Cant connect qxdm to htc m9
I read in the HTC One M9 forums that users with CDMA phones could change the 06828 value, while I, using a GSM phone, have been able to change 06829. I guess this is some kind of protection Qualcomm/HTC/whoever put in place to avoid users messing around with this stuff. I've managed to put the phone in diag mode (for those who don't know how, I'll leave a little tutorial in the end of the thread), but when I write the value and then read it again it's back to its original state. After a lot of reading here in XDA, paying 25$ to be S-Off, flashing radios, changing roms and kernels, and a bunch of other stuff, I've come to the conclusion that my only alternative left is to change the 06828 NV value (which determinates what LTE bands are activated) with QXDM/DFS tools/whatever program.
I can't return the phone though, since I'm from Argentina and with the insane customs ruling here, sending the phone to the US and back would cost me almost as much as just buying selling mine (at a highly reduced pricepoint since it doesn't support LTE in my country) and buying a new one. Hi! So I bought a HTC 10 from Amazon back in May and, even though the product description said it was the US version which had LTE bands for US carriers (specifically 4-AWS), they sent me a M10h, which is the international/asian version that doesn't support band 4.
