Note 3 Test phone - Doubts?

Hi,

I've just got from a friend of mine a Galaxy Note 3 (those used for testing/show off at stores).
All working fine despite SIM which is not working at all.
There's a SIM slot however with or without SIM its the same.

Does anybody know if this is a HW limitation (which needs to get the board replaced) or just disabled by SW ? (it would be awesome, however too easy if it is that way :laugh:)

Thanks

Cheers,

New around here. Some doubts.

Hello.
Ever since I bought a Galaxy Nexus and found XDA, my life changed. Without noticing I got infected a virus: addiction to Android.
My Nexus got outdated quickly and now is pretty done and I need a new toy. 3,5 years later I finally got some spare money to buy a new phone. Since here in Portugal the minimum wage is around 500€ and top flagship phones cost around 700€ (and there's no affordable contract to get something cheaper and still nice), I had to wait until now to get a used Note 3 for 300€.
I love the phone's design and above all the specs. There's no other phone with 3GB RAM and Snap 800 for this price and I always liked big sized phones.
Well, I write too much unnecessary info... I need to stop :D
Let's get down to the point. I will get the phone tomorrow!!

TL;DR
How do I check the bootloader version? I want to flash TWRP right away and maybe install a Note4/5 port or something stock Android, do I need to be careful with the bootloader?
I know from other phones (i.e LG G2) that any custom rom uses KK bootloader and the stock roms use their respective version bootloader. Is this also true for the Note?
Also, which version of TWRP should I flash? Does it depend on the stock rom version that I have?
Checking if the device has 2.3x GB of available RAM, if Odin and Recovery have their stock aspect and if the S-Pen works is enough to ensure that the Note I'm getting is truly original?

Well, that's all. I'm sorry if I'm asking the same questions everyone does. I'm used to Nexus so I'm afraid of bricking the Note with dumb moves. That's why I am taking my time to read every important thread and asking here some doubts that went into my mind while doing the required reading. I have no warranty (no box nor invoice) so I can't afford to mess up with the new babe :D

Cheers!

Some doubts

Hello,
I have being having some troubles with my oneplus one. Today I recieved a notification saying that a new update was available so i downloaded and tried to install. However I didn't realised that i had installed the twrp so i was unable. As i wanted the official update I installed a stock recovery and try to install the update, but it failed. Don't know why it failed... i assume that maybe i didn't installed the appropiate stock recovery. However i finally installed the update by using the "apply update (option in the recovery)" to the official zip file i had previosly downloaded. My question is, for the next update will i have to flash it or just a normal OTA update? (i think that my problem was that the stock recovery was not the appropiate, so I just wanted to know if my recovery has been updated to the appropiate one with the manual update)

Another thing what does the lcd density option does?

Thanks, sorry for my bad english if you don't understand please ask me
