[Q] Help with terminology (JVP, JVQ...) - Android Software Development

Acronym explosion!!!! Please help me with some terminology please. I would like to know what is:
1. I know JVQ is a modem, but I've also seen a million similar 3 letter acronyms that i only assume are modems also, such as JVP. Are all modems JVx?
2. What about some of the other 2-3 letter terms. KC1...
I am familiar with other basics, its just when these letters/numbers are tossed in out that I'm not sure exactly what they are.

JVQ and JVP and such are not modems, they HAVE modems. those are the identification numbers for the ROM's
JVP came before JVQ fi you notice Q is after P in the alphabet, now JVP has a JVP Modem as well as a JVP PDA and it's CSC, all 3 form 1 ROM.
the part where you get told where are they from is the one BEFORE that, as in I9000XXJVP
that is the full name of the rom. it means it's for the I9000 device or Samsung Galaxy S, and it's a XX country code, this means Europe, and it's designation is JVP.
you can find a list of country codes with a search in this forums.

[Q] How to identify where your Note is made?

I got my Note from Expansys.ca few weeks ago. I rooted my Note and wants to update it and keep it rooted. What firmware should I download?
PCode:GT-N7000RWAXEU
PDA:N7000XXKKA
PHONE:N7000XXKK5
CSC: N7000XEUKK3
and where can i download the latest firmware? Thanks
I would suggest the EU in your code says its a european rom, therefore id us an open europe from samfirmware or indeed from here.
It doesnt matter to be honest, all the roms are virtually the same, just some are tailored for different networks, im assuming yours is an unlocked Note, so any rom will work fine, all roms regardless of country also have the english language, so go ahead, download and flash, its no big issue what stock rom you use.
If you decide to go custom, PLEASE be aware that guides are on here for a reason, familiarise yourself with the process completely, so many people dont bother to read the posted guides and wind up in big trouble.
Please do some searching in the Note forums.. everything you ask has been asked 100 times before..

Which Modem(s) should I Install on my Galaxy I9000?

I have an I9000 on which I've installed a CM7 ROM I built. It works fine but I'm confused about modems. The modem.bin extracted during the ROM build was I9000XXJVK. It works but can't seem to do 3G (I'm in the US on AT&T). I've seen lots of chat on the web about this-or-that modem.bin for the I9000 (like 60 or so).
Q: What's the general differences between modem versions for this phone?
Q: How do I know which to use? Are they interchangeable?
Q: Are they country-specific? The chat seems to say mine is for Europe. Is this maybe why I'm not getting 3G?
BTW: The 3G-not-working problem is only an interesting clue. What I really would like is a brief tutorial-ish blab about modems for my education. Answers like "try them all" are not helpful for this.
Thanks,
-John
Have started a topic about this here : Link

They are country/region and even carrier specific.
I'm glad with modem of JW8

Basebands

Hello,
as I am completely new to Samsung, I have got a question regarding the different basebands.
My S4 is running XXUAME2. New custom Roms are using different versions (for example XXUBMF4). and what is a CSC?
I couldn't find information if it is important to stay at the same baseband version, wher the differences between the basebands ar.
Can anybody please explain me?
Thank you!

I would also love to get the answer to this question +1
Thanks
Basebands are the same as the radio. They can improve your signal, and i some cases even affect other things like camera quality.
Newer basebands are nearly always better.
CSC is country code and you should try to find a code with your country
makhakz correct me if im wrong but csc's and modems are two different things altogether. my advice would be to leave csc alone as its allready set for you and just flash a different modem.
some modems may increase speed and connectivity others may improve these.
its a case of trial and error really as to which one works best for you

[Q] Questions about rooting, region locks, efuse

I have a few general questions I hope some people can answer to help me understand these topics better, numbered it for ease of replying.
1) For unlocked stock firmwares, what is the point of Samsung having multiple firmware files for different countries/regions? If you go to sammobile's website, you can see what I mean. I understand having different firmwares for different providers as they have their own bloatware/branding. But unless the unlocked firmware files contain different languages for different countries/regions, what is the reason for multiple unlocked firmwares? Gets confusing when choosing a firmware to flash your unlocked device (if I should choose UK or Germany, for example - and I'm sure both would contain the English and German languages anyway).
2) Is region locking now a non-issue ever since CF's region lock away solution? I'm assuming if I had an unlocked phone with original firmware that was not region-locked, that I shouldn't have to worry about upgrading to another unlocked firmware (that does contain region-locking) since CF's solution works? Or should I be worried about upgrading into a firmware that does have region locking?
3) Do all firmwares that contain Knox have the potential efuse trigger? And if so, what actions trigger that efuse? I gather from reading the forums that normal rooting triggers it (the DLV method excepted). But what if I wanted to flash my unlocked device with another stock firmware from another region (because I liked that firmware better) - would that trigger the efuse as well? Any other conditions/activities that would trigger the efuse?
Thanks in advance for helping me out with these n00bish questions.:good:
Anyone want to take a crack at these questions? Thanks!

1. The different firmwares have variations on carrier specific bloatware and/or regional basebands that could impact your connection, although in reality, I've never had any problem using other modems on various Samsung devices in my region. This tends to vary quite a bit by region, so sometimes it matters, othertimes, it does not.
The general rule is to stick with your region if possible, but otherwise, if you want to avoid bloat, any firmware is possible as long as you make sure it's for your specific variant. That's the biggest caveat.
2. CF Region unlocking only works for the 9005, so Exynos based International models are not supported. Ony time will tell how long the exploit CF has found will actually be viable in future firmware updates. Things could change overnight.
3. Firmware versions beginning with J3 and above have the Knox bootloader, as far as anyone can tell at this point. I used to care about the Knox trigger, and it really pissed me off with the S4, but I've come to accept it as a price one must pay. In reality, all major players are working toward this "safety" goal. LG has their own version of a locked bootloader, etc. What triggers the Knox eFuse is custom ROM/Kernel/Recovery. Rooting alone isn't really enough to do it.

Not bloatware no, more carrier information, APN - http homepage/email set up etc. Unless it is a carrier's firmware rather than an unbranded firmware (unlocked)

Agreed. But you can install another region firmware if you wanted faster updates, or an update which is region specific

Right. I just meant to say that some firmwares are carrier firmware and others are open and tend to have less carrier branding and bloat in them.
Wow thanks guys for your detailed replies, much appreciated.
1) Yea, regarding the multiple firmware choices, I understand the need for separate firmware files depending on carrier-specific requirements. However, for a specific model of an unlocked/unbranded phone (say, the GT-I9505), the hardware should be identical regardless of where it's originally sold in the world. So it looks like the only reason for having multiple firmware files for say an unlocked GT-I9505 would be to include different languages. Why not just have one firmware file for a given unlocked phone and just include all languages? Unless I'm missing something here. A little confusing when I go to download a firmware file for my unlocked phone and have to wonder which choice contains the "best" upgrades.
2) So from what you say, as of right now, the N9005 version of the Note 3 is susceptible to CF's region lock away solution, which is great. Is this also true for all other Snapdragon-equipped models like the Galaxy S4?
3) So the Knox efuse becomes an issue only if you seek warranty work, correct? It doesn't actually hinder or restrict your ability to mod the phone even after the efuse is triggered?

Yup different languages and region specific updates (Poland tend to update before UK for example)

It seems it works yes, a few conflicting reports, but 9 out of 10 seem to be ok, as for other models I'm not sure

Well yes and No.
Samsung are honouring some warranty work with 0x1 and sometimes they are not.
As for things working correctly, once tripped to 0x1 you cannot use KNOX functions, encrypt your containers etc. - Possibly be one or two other things you can't use that may not have been found yet(?)
But no it doesn't restrict anything once triggered bar what I posted about.
Will ChainFire's Region Lock Away TRIP Knox...if rooted with Knox not tripped?.

OG5, OG7, PC1, what does that mean?

Ok.. So what does the last two letters followed by a number mean in a baseband version?
Mine right now is N910PVPU4DPC1. So PC1. What does that mean?
It's unrooted, Samsung Galaxy Note 4 Stock Rom.
Anyone can google that, and figure that out.
What does OG5, OG7, PC1 mean? What is the relationship between OG5 & OG7? Besides the fact that seven is two numbers higher than five.
Anyone have knowledge on this, or can point me in the direction, of where I can learn more about the three ending characters in a baseband version?
Anyone care to explain to me why I need to be on a certain baseband version, in order to use a specific ROM?
