[Sprint HTC One (M7)] Tilde88:
Hi everyone. Firstly, I wanted to say thanks for this amazing guide and thread.

The reason I am here, is because I have been working on my Sprint HTC One the past couple of days. It is currently HBOOT 1.44 ( S-OFF with eng-style commands accepted), SIM unlocked, rooted, SuperCID (1111111). Anything that could be unlocked/rooted has been. My new carrier is Cricket (GSM on AT&T towers). On my HTC One (M7 WLS - Sprint), I am only getting Voice and text.<br>

I have ensured that the APN settings are correct, I have enabled GSM data, and removed any roamguards for GSM. No matter what I do (and I have done it all; I've used QPST to change settings, I've followed any and all guides I have found, I've followed the guides to the T, I've also tried the same guides with my own intuition tweaking where necessary. I am by no means new to this kind of stuff. I even used the HTC One Sim Unlock Helper instead of typing the terminal command. Lol I know I didn't have to since I SIM Unlocked previously, but still. I have also used Region Lock Away (chainfire). Still only Voice. <br>

Worth noting, on every reboot, my custom-made APN gets modified by the system, it leaves all my fields intact except for the APN field, which it changes my value of "ndo" (which is the cricket/aiowireless APN name), to "cinet.spcs" (the cinet.spcs is a Sprint APN). Even after modifying it, removing it, making a new one, and TRIPLE checking that there are no errors ("default,mms,fota,hipri,supl"), I cannot get 3g/HSPA+ (I know LTE will not work). I set the phone type to WCDMA Preferred. Only get Voice. I set it to GSM/WCDMA/LTE, and it just reverts itself to WCDMA Preferred. If I set it to GSM Only, or Auto, or Global, obviously nothing works, but they stick, they dont switch to WCDMA Preferred.I've done a ##DATA# restore profile (blank out anything I might have changes), I've done a ##SCRTN#, to remove any activation info, and followed up with a ##RTN#.

I even RUU'd to 1.29.651.7, re-unlocked bootloader, re-did S-OFF, downgraded to initial release radio (my baseband versino on my phone shows "1.00.20.0315", build number 1.29.651.7 CL166937). So I am definitely on 4.1.2, with proper HTCOMADM apks and whatnot. I am aware that later radios and system updates either blocked certain GSM freqs, or disabled HTCOMADM functions. The only thing I have not yet done, is try the Baseband 1.00.20.0626 radio... I know it's not the release one, but meh... What do I have to lose? I can flash back to 0315. So ill try the 2nd release radio and report. Hopefully you guys have some info for me in the meantime :-p

My Sprint Note 3, I have fully unlocked as well, the same SIM works in the Note 3, gives Voice, Text, Data, and MMS. Using the same APN settings. On the Note 3, I use GSM/WCDMA/LTE, and get HSDPA+ at 5+ mbits/sec. I am literally at my wits' end, and could use some fresh ideas. Remote assistance is also welcomed. All ADB, Fastboot, DIAG, and other drivers are already installed and working if anyone wants to poke around QPST or anything else. Also, I am in Florida, and as I see the 1900mhz spectrum is 99.99% available. I know I am not the only one with this issue. I know many are able to get on T-Mobile with many less issues, and have found very ve4ry very few posts saying AT&T (cricket or otherwise) was successful. Furthermore, I've not seen any pictures of the Sprint HTC One successfully connecting to AT&T Data.<br><br>

Thank you all in advance, and please don't worry about being too technical/advanced, I assure you I can manage whatever you throw at me.
