[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SkyboneNoya:
For future reference (if the next Quantum update CM LTE BUG is still a problem.

If you have lost LTE and are locked to 3G/H+ data or have dropping network/cell coverage and cannot get it back in working form. Even after using (*#*#4636#*#*) dial code settings, Mobile Network Settings GSM/WCDMA/LTE, several reboots + backup restores and fresh installs to try and restore LTE functionality yet have failed. This is how you can get LTE to work again.

First off. Make a backup of everything, titanium, nand etc right to the PC/MAC. Then FLASH QUANTUM 3.5 as of Tues, Feb 25th 2014 to see if it fixes the LTE bug for you.

If 3.5 didn't work follow my first option below.

#1. I restored my backup of OTA 4.3 stock from cwm, which I backed up after gaining root in November. I couldn't get LTE to work for the life of me after flashing 3.45 Quantum and remembered getting back to stock was they key on my old android phone when getting my 3G connection/imei to correct itself. Once you run 4.3 stock turn LTE on reboot and restore your previous working backup.

#2. I didn't see much about flashing or using odin to get back onto 4.3 stock after already receiving the 4.3 update but I think it can be done as long as you don't downgrade lower, "example 4.2.2". Although the new 4.3 is very sketchy and I was not able to find out if this process was safe or not "sorry" there is also a unbrick and a downgrade guide from 4.3 to 4.1.1 posted in General forum of "AT&T, Rogers, Bell, Telus Samsung Galaxy S III".

Reading information.

If you decide to use the 4.3 odin #2 method overwriting your current 4.3 bootloader first read into the mentioned guides and before anything make sure you create backups of everything to the computer and use the correct stock rom supplied by your carrier. If you have not done so also backup imei, this is a big one for sure which should be done before flashing any custom rom.

Sorry I couldn't be of more use on the second option, but having working backups is just a no brainer so I went with the sure fire way. :cool: If someone can elaborate on the #2 option I can add this in and will even save it to my signature for future reference if its still suitable. (didn't install Quantum 3.5 yet as of writing this) so here's hoping for the best!

Cheers.

Micro ATX yeah that might be the main problem. I would look into a new case! the Fractal Design cases are beautiful! and honestly I see some positive reviews on customer relations in regard to replacing broken or missing parts. I used some Arctic Silver 5 thermal paste on my rig haha I know its old but after 200 hours of cure time it is pretty sweet I think. Although new stuff is probably better.

You need to think about good cable management and bigger fans for good airflow and quiet operation, 140mm fans is where its at.. Can't wait to upgrade (or downgrade depending on how you look at it.) be going from 5 120mm fans and a 200mm top fan to about 4 140mm fans with a Fractal case.

Yeah, I didn't see much about the fan controllers but I have a few in mind and even then after market fan controllers seem to be pretty flaky as well. Currently I run everything right off my motherboard fan connections except for a few going off my 850w corsair..

For anyone considering corsair DON'T SETTLE with a TX brand. AX is where its at!! upgrading that in the next few days.. AX860i Corsair FTW!

EDIT:

Here's a little eye candy of a Arc Midi R2 build http://www.malikcustoms.com/air-arc/ one click front fan filter pops out, there's top and bottom filters and fan mounts as well.

Just great stuff! PS. I put some thermal compound/paste on my old gtx 480 in hopes of getting it to cool down a bit and it didn't really help. I think it might have dropped by about 1 degree C or so.
