I just followed the bootloader instructions and then followed the way to root the phone.

TWRP

SuperSU

From the video used.

Alright so I'll start from the top, I have the HTC One M7 from T-Mobile and I purchased a Straight Talk SIM plus service and went to install everything.

I was originally on T-Mobile but they upped my bill to 80 a month, so I switched to MetroPCS but MetroPCS is really slow down here so I decided to switch to Straight Talk but I just read online that they are both on the T-Mobile network and are both the same in regards to speed...(so my mess up I guess? Unless that's not right.) I am in Tuscon, AZ.

Anyways, I tried changing the APN and it just kept disappearing I used the most basic setting at first and it kept switching to the LOCKED T-Mobile APN and the internet/mms won't work only calling/texting.

So I tried using a more advanced APN and instead it just disappeared, it won't save even after I touch "Save" so my search began and I saw things about Sunshine but I didn't buy this phone outright I got it a year ago online for 200$ and I am completely broke right now so I can't afford the 25$ but I need to be able to use my phone because I already paid for the coverage (Straight Talk) and I am trying to get in contact with a potential job.

So to reiterate I used both basic and more detailed APN information neither works, first one saves but goes back to T-Mobile's APN, second one doesn't save at all it disappears. I went to Straight Talk and got the APN information but once again nothing worked.

So I read online about using Titanium Backup and converting APN Backup And Restore to a system app so I can alter the APN, but I every time I tried using TB(I paid for it by the way so I can use the full version) it would hang on, "Processing please wait" I waited well over thirty minutes. I restarted my phone and for some reason the app was deleted.

So I continued to look more and found out about the S-Lock and Rumrunner, so I continued on with that and tried using Rumrunner but the ADB thing wasn't installed so I used this link, (http://xdaforums.com/showthread.php?p=48915118) tried again and I got all the way to the end (after disabling firewall/antivirus) and was stuck with the "Get unsecured" kernel error, the "Choose one of two options, bye!!!" message. So I looked into that as well, I found this one called, TrickDroid ROM (https://www.youtube.com/watch?v=5KEesTRHixE) I did all the backing up using TWRP and TB then proceeded to go to (http://lifehacker.com/how-to-flash-a-rom-to-your-android-phone-30885281) I put the ZIP file in my phone then went to TWRP recovery, I went to install it and it just hanged on the "Flashing 1 of 1" I found out that it had something to do with, "Mounting" or whatever in TWRP and I didn't so I restarted my phone.

I tried going back into recovery mode after the restart multiple times and it wouldn't work, I picked it and it just loaded into FASTBOOT every time and wouldn't load the recovery mode. So, once again, I looked into this and found Squabbi's HTC One tool kit, 3.2. I downloaded it and got it to work on my phone, I followed these instructions, (http://forums.androidcentral.com/ht...48-htc-one-won-t-boot-into-twrp-recovery.html)

Reboot to HBOOT

select FASTBOOT to get to FASTBOOT USB mode

Make sure the device is in and you have fastboot on your machine

fastboot flash the recovery image

Immediately try to go into the recovery via the HBOOT menu

If no dice, reboot the system and make sure "fast boot" is unchecked in the power options. It might be unrelated, but still: do it.

Go back and try again, but after flashing recovery, reboot the bootloader and then immediately go to recovery.

If successful, reboot system then reboot back into HBOOT and then to recovery to confirm.

I went into the tool and used "Recovery," I downloaded the TWRP one for T-Mobile and clicked on, "Reboot Bootloader" then it restarted my phone and put me in the white screen, I did the flash recovery and everything went through so I went into recovery.

This is where I am at right now, I went into recovery and TWRP is saying I have 0MB internal storage but when I plug the phone to my computer I can see everything is still installed. Also, usually I read online when people have this problem their phone doesn't work at all, strangely enough mine will boot into the OS and allow me to make phone calls text and use apps, so basically the phone ITSELF is unaffected, which I haven't seen on here so either I'm a crazy exception or people just don't post a lot on here.

I also went back into Squabbi's tool and got the error that my device is offline and now I just got the error (Permission Denied)

To reiterate, my TWRP says 0MB internal storage after doing a flash recovery and I went to "Wipe" and cleared the dvleck (or something) and the cache before trying to do the install of the ROM trickdroid but my phone still completely functions.

My HBB is 1.7 I believe and I am not sure what other information you'll need, all the sites referenced above is everything I've tried and used. I know Straight Talk works on this phone because as long as I can set the APN I can successfully use it.

Please don't respond with, "If you can afford this phone blahblah code" I could afford the phone two years ago when I had a job and money, but that doesn't mean I can afford the code.

If there's anyone that can help me I'd really appreciate it.
