[Q] [i9195] General custom ROM question for S4 Mini

Hi guys,
I just ordered a Samsung Galaxy S4 Mini and I am fairly certain, that I want to use Cyanogenmod on this device. Unfortunately there are no s4 mini custom roms released yet, so I thought I would try to port it myself. While this is my first android phone, I have gone through the flashing process on the phones of a few friends and I am a long-time linux user and developer, so I feel pretty confident, that I can do it.
I did some reading, but still have a few questions:
Is it correct, that Samsung smartphone bootloaders are generally unlocked? (Unless it's a carrier specific version)
Is it correct, that it is not *required* (but useful) to have CWM recovery (or similar) on samsung phones to install custom roms?
Heimdall or odin can flash them anyway?
What would I have to do to permanently brick the device? Can this happen if I mess up the kernel, recovery or anything else?
Is this guide a good resource for porting CWM to the i9195?
Regards,
Flyser
P.S.: Can we have a seperate s4 mini section in this forum?

bump

plz if u got any rom for s4 mini >> plz give me a link .. i need to port it for my htc sensation >> thanks

cyanogen might work. or maybe some rom from similar device.

some news about?

This is ridiculous... how isn't such a mainstream device supported? It's the top selling phone currently in my country...

Maybe you don't look in the right Forum section? the Root Kits and CRoms are currently in Development. Looking here http://forum.xda-developers.com/showthread.php?t=2364980 So be patient. Don't forget there are all Homemade.

[Q] [NOOB] Help building custom ROM for S5 G900H

Hey guys
I'm currently working on my first custom ROM mainly because there are currently no ROM for the dreaded G900H (aka Exynos) version. For this, I already downloaded a stock ROM and created my environment using Android Kitchen. So here are my questions:
1. I was able to follow and execute all the instructions to extract the custom ROM, install root and busybox. But first... is Android Kitchen even compatible with Galaxy S5?
2. Is it important to keep the CSC info on the new ROM? How can I backup current CSC info from my stock (carrier provided) S5?
3. How probable is to brick the phone if I flash a very alpha ROM as the one I'm supposedly cooking? I already have a nandroid and EFS backup
Thanks in advance for your answer and patience.

Funny, implying that this is an statistics game. It is not and it's ridiculous to blame developers for the lack of support.
Pretty much everyone that actually develops got the Snapdragon variant, if I had a choice I'd gotten that just by the amount of code and AOSP possibility.
Exynos was only supported by a couple of devs, it's all Samsung's fault - not devs. None of them currently has an S5.
Use xposed, greenify, titanium backup and there are few reasons you'll need a custom rom.
Xposed opened a new world of possibilities to modding.
Edit: Exactly that demanding attitude is what puts devs off. Other regions are usually more polite and grateful and that's something devs have noted in the past....

Sorry if I didnt make myself clear. English is not my first language. When I mentioned the millions of user was only to imply that more users, the more chance to have a genius among them. I didnt mean to have a demanding attitude. I was trying to say "Iknow you are out there, I know you are developing something for all of us. We are here waiting for your effort.

@CiDev:
You want to share your ROM for "H" here?

i dont think that will we have any custom rom for our model
but according with this http://forum.xda-developers.com/showpost.php?p=52168627&postcount=168 @Shohat told me that he will release custom rom until end of may,,but nothing..
maybe he is busy

I wouldn't bet *anything* on it being released, it looks to me like an abandoned project...
The whole 'I can't work on this because I don't have money' turned me off instantly from that ROM.
On topic: I have been working on a custom kernel for our device, mainly trying to improve battery life. I'm still testing, if it's worth it, I can release it.
It's based on the contributions of others, so it wouldn't be fair for me to keep it private, I just don't want to release something that will break stuff.

1 - yes.
2 - make an nandroid before
3 - if you have a brick, restore from your nandroid and ready again

[Q] Different Threads for GPE and normal S5?

This is directed toward the Moderators - Seeing as the Google Play Edition is a different phone than the normal SM-G900V, can we get a different section of threads for each??
I don't post a lot but I spend a lot of time on XDA. I'll try just about anything with my phone, but I am by no means an expert. I currently have the VZW SGS5 (SM-G900V). I am rooted with Super SU Pro installed and working great (SU Binaries updated and Knox Disabled). I have just installed Xposed for the first time and am looking for other things to do with my phone. As soon as SafeStrap or another method is working to install Custom ROMS (TW Based or otherwise) I will most likely do so asap.
Maybe I am not understanding their similarities, but it seems logical to have different threads for these phones so that we don't have to sift through things that pertain to a phone we do not have and possibly even try to install something that is not meant for our phones.

After we get some kind of custom recovery for the retail version like safestrap I would like to see all the DE threads moved to the Verizon Galaxy S 5 Original Android Development section like it's done in the VZW Note 3 development section. It would cut out a lot of confusion as well.

[Q] Lost when it comes to "unified"

Hey all,
I am looking around this forum and I see a ton of ROMs. I am a little confused about what Unified means. Does that mean any ROM should work on any Note 3? Or do I have to make sure it says hlte somewhere in the description? (I have the Sprint variant). So many ROMs to try, just want to avoid problems. Thanks!

CyanogenMod has de-unified their builds. Branching into hlte - hltespr and hltevzw. I don't know if this is also the case with TW-based ROMS. Better read carefully the instructions or better yet just browse through Galaxy Note 3 Sprint section of xda dev. You should find everything that's compatible with your device there.

Originally CyanogenMod had seperate builds of Note 3 CM ROMs, but then they decided to merge all model specific CM's together to make "hlte". This is their so-called "unified build".
"hlte" is the Note 3, however there's no such thing as "hlte", as models are classified as "hltexx" (N9005), "hltespr" (N900V), "hltevzw" (N900S), "hltecan" (N900W8), "hltetmo" (N900T), "hlteatt" (N900A). As they all have the abbreviation "hlte", CM took those four letters out and created a build that works for all variants (if applicable on the device).
When the de-unified their builds, they created an "hlte" build but for the specific device that fits it's drivers and set up. I believe they did this in order to stabilize their builds. When they unified them all, I read somewhere that the video drivers caused issues leading to random reboots - even if this isn't so, unification and sharing of common drivers isn't always the best, you would want model specific drivers to take full advantage of your device, and to eliminate common problems that appear on different models of the device.

Only for CM and not TW.

Custom ROM's and CWM recovery for SM-S820L?

I have been into modding my SM-S820L for a few months now and although I have found an unofficial TWRP release and a few stock ROM's from various sources, I have never seen any type of CyannogenMod ROM or other custom ROM for this phone.
Also I have been wondering about compatibility between some of the other Samsung Galaxy Core Prime models or similar Samsung phone in general. Would it be plausible that a ROM for say SM-G360T would run on an SM-S820L????
I would love it if anyone knows about compatibility between the SM-S820L and other Samsung Galaxy phone's firmware and custom recovery releases and is willing to share the knowledge would post here with some advice.:laugh::good:

Sm s820l
I'm in the same boat as you, there's just not much out there, a new rom was posted on area51 but it wasn't much different, just got rid of bloatware as far as I could tell. I look at it like it's a cheap phone, and as far as custom roms and such, it's just not popular or not favored. I've spent hours searching, nothing out there but malicious websites lol. I'll keep you in mind if I come across something.

Head over to NEEDROM. I built a modified ROM from the Stock firmware for the SM-S820L.
Here is my post!!!

CM, PAC, etc, ROMs for other variants of the Core Prime definitely aren't compatible with the 820L variant? Nothing available but stock-based ROMs?

As far as I have found on the Net, and I have searched for countless hours, I havent found any truly custom ROMs from CM or any other ROM makers. All of my modded ROMs and Kernels are just modified stock files. I havent heard of the other SM- variants being compatible with the SM-S820L but if you ever do find info that certain ROMs work with this model, please post here or shoot me a PM.
I would be uber happy to finally flash something like a Cyanogen Mod ROM

An acquaintance of mine just got a Core Prime, so I was looking for info to root and ROM his phone. If you, someone who's actively been looking for the info hasn't found anything yet, it's pretty unlikely that I will. Looks like he just had the crummy luck of ending up with the variant that doesn't have much dev support. Thanks for the reply, though. People over in the SPH-L720 section don't tend to be nearly so helpful.

Is his Core Prime model SM-S820L? If so, I remember using Kingroot to root and then SuperSu Me to remove Kingroot and retain root. You can find SuperSu Me in the Aptoide app store.
After I rooted my phone, I installed TWRP with ODIN3. You do need to have the Samsung Drivers setup and Kies3 installed to have all needed drivers in order to use ODIN3 in your phone's download(ODIN) mode.
