HTC M8 HK on sprint bootloop after fix permisions in TWRP

Hello all i have a M8 HK edition on lollipop from the us on sprint. ( i am in Europe)
I was trying to get sim unlock and i got as far as installing the TWRP on it after unlocking the boot-loader.
i was in the stage to install the super user zip with the help of TWRP but somehow i manage to hit the fix permission button in there.
I tried all the simple way out there wipe-ing all the caches / factory resetting but nothing no goo.
I want to put the original firmware on the phone but i really need some help to lock the boot-loader and to do that i need to S-OFF as i am S-ON now.
and if you can point the right firmware or recovery image for this phone it wold be fantastic.

Any info you need just ask and (tell we how to get it, if its complicated)

Noob Sprint Galaxy S3 Bricked? Newb!

So a buddy of mine offered to install some custom software in my Sprint Samsung Galaxy S3(SPH-L710).

The phone will now boot to the splash screen and do nothing but stay stuck there. I would just like to get the phone back to normal but the phone was never backed up before this was attempted.

I'm in dire need of assistance to get the phone to perform how it did beforehand.

What do I need to download, install, anything, to get the phone working again....

Sprint S4 LPH-L720 Drops Data

The history of my S4 LPH-L720:

1. I bought this when it was first released in May of 2013.
2. I've been using custom roms for a solid 2 years and the issue just started within the last 6 months.

The problem:

1. Recently it's been dropping the data connection completely, which requires me to cycle airplane mode to get it back (cycling Data Connection does nothing).
2. This happens with LTE and EVDO connections, but if I force it to CDMA (1X) then I don't experience the data drops.
3. This is happening with multiple Sprint towers as well.

My questions for the community are:

1. If my phone is slowly dying then I'm considering another Sprint S4 (L720 not the L720T) on eBay, but I wanted to see if others with the original S4 are having similar issues with data connections, in case it's a Sprint specific thing.
I need the non-spark model because I can use voice and LTE data at the same time. This is very handy when I need to tether and still use my phone.
2. Are their any Sprint LTE bands that this phone is incompatible with that could be causing this issue?

Thank you for your input!

Nexus 5 + Marshmallow + Sprint = no LTE (+ no wifi, authenticates, but no ip)

Installed OTA Marshmallow as soon as it became available on my stock Nexus 5 with Sprint service. Now, two days later, I can't get an LTE signal, just 3G. Also, my device has been unable to obtain an IP address from WiFi - it seems to authenticate, but no ip is resolved.

Has anyone else seen any instability with Marshmallow? Is this just a Nexus 5 issue? Is this just a me issue?
