I have a rooted r800x phone with 2.3.3 running on it right now. The phone is cdma. I installed cwm on it via the xperia app from marketplace (locked bootloader still). My question is where csn i find compatible cfw for my phone and how do i go about installing it? also if there is anything else i need to know please feel free to mention. This is my first attempt at cfw on a phone. I really want to overclock the phone so any help is appreciated!
All firmware files can be found in the Dev section along with instructions (note the ones with CDMA in the titles).

Unfortunately with a locked bootloader you limit yourself to only stock based ROMs, and it also rules out overclocking. The reason being is that for other firmwares (CM7, CM9, MIUI, etc) you need to flash a custom kernel (the kernels also what allows you to overclock along with some other low level tweaks) and you can't do that without unlocking your bootloader.
*EDIT* And since people keep telling you you need to flash a kernel to do anything, here's the first step:
http://forum.xda-developers.com/showthread.php?t=1322827
Read that, that's how you unlock your bootloader (it costs $24ish last I checked), you can't overclock without it, sorry, that's how it is, it's the only way. After that you still need to flash a kernel with fastboot, which is a process in itself. So read up, there be good information in these here threads.
Hi!
Bought this i9506 yesterday, after getting tired of LG Optimus 4X HD. Wanted Full HD, and a black phone (my LG was white).
Got a bit dissapointed when i saw there's no custom ROMS for this phone yet though.. After all, this is taking over for the old S4 (i9505), at least here in Norway.
What happens if i try to flash a i9505 rom? Will it just say that it's not compatible? Haven't dared to try yet..
It's allready been rooted with the Philz Touch CWM.

I am pretty sure that the phone will not boot. The chipset is diffent and something else that i dont know

Yeah, i guess you're right! SnapDragon 600 in the i9505 vs. 800 in the i9506..
But also, i think the manifest is beeing checked by CWM to check if the rom is the right one..
It's a shame! On my Optimus 4X HD i were hasseling around with building CM11-roms from github/P880-Dev, but since the camera did not work, i just bought this.. Now i guess i have to look more into developing, and see if i can convert a Xperia Z1 ROM to this one!
I tried and Odin fails.It says something about the signature.It's like trying to flash i9505g rom on i9505 wich have the same SoC.It's not possible.

Yeah, i can see the signature-problem.. Maybe we could just change the signature-files on a i9506g-rom!
That would be nice! But i think the Note 3 is more similar to the i9506. So it would be much easier to port a rom from that. I have no magic dev skills but my phone is ready for testing.
It won't work.
Hardware is completely different.
I9506 is similar to I9505 the same as similar to I9500
Don't look at Qualcomm Snapdragon name. SD600 and SD800 are different very much.
Don't waste your time for this. You will only get results varying from "can't boot" to "brick".
sorg.
Thats good to know! Thought they very almost the same.

Yeah, but perhaps if we get a CM for Note 3, that we can modify this instead..?

yep. CM from Note 3 can have good compatibility. But first you need is to get Kernel source code of I9506 and Note 3. Then you will need to transfer CM related changes from Note 3 kernel to I9506 kernel.
After that may be you will be able to boot CM. Not sure. I never worked with CM sources.
I wonder does Samsung contain anything device specific in the system portion of the image? The SD600/800 drivers would be in the kernel/boot portion no? Certainly on normal Linux you can transplant the hardware and only need to rebuild the kernel.

There are many device specific files in system image. There are many user-space device drivers. Also, Samsung doesn't make any HAL (hardware abstraction level) in their ROMs. Even devices with the same CPU have many incompatibilities in ROMs. For example RIL from Note 3 with SD800 doesn't work in E330S ROM, producing endless reboot cycles, although modem part of SD800 is inside SoC (unlike other SoCs).
Ah, better example: system image with Android 4.3 from I9506 doesn't fully work in E330S phone (camera doesn't work), although 4.2 system image worked fine. It's because development of these two models went by separate ways by (probably) separate development teams. I had to take some parts of i9506 kernel source to make E330S kernel compatible with I9506 system image.
I've try to flash the Note 3 Omega rom the phone works. The wifi and bluetooth do not turn on and the cellular network intermittent disconnect so I think if we can flash on a customized rom for note 3 that integrates libraries and drivers for the gt-i9506 it would be a good start.
/!\ Do not try to repeat what I did, my phone not at all want to connect to the cellular network even after reflash stock rom 4.3 with odin, phone boot, logo becomes dark we feel small vibration indicates that the boot is over and it stops there, after a while a message "system is not responding ..." then reboot. When I reflash with odin there is no error message, this is what is called playing with fire
Well, we have official Samsung sources for 4.3 (I9506XXUBML5).
Someone who have time to learn how to modify it with root and then compiling it would be easier task than try to modify other phones rom's.
Damn, I just baught this phone, I'm picking it up tomorrow.. Quite a bummer not to find any CM ROM's for it. Wellwell, maybe touchwiz will be fine with the good specs the phone has. I just love cyanogen so much
You guys think it will come eventually?

Sure hope so, i did the same "mistake" as you, thinking there's NO way there isn't any CM for this phone.. I think it's the last phone i would'nt have checked first before i bought it, but still, i should have!

Yeah me too. Thank god it's sooo fast and smooth! I hate all the bloatware tho, I think I will root it in a few weeks to remove most of it.

sorry to hear that your phone cannot boot... there is a price for trying and development anyway. you may get it fixed when there is compatible rom available

How can you make the E330S kernel work with i9506's 4.3 rom?

basically, kernels from E330S and I9506 are almost the same. On 4.3 ROM there is difference in Camera interface, so E330S kernel won't work with I9506 system image. But you can use source code from i9506 to compile kernel for E330S device.
Starting from 4.3, both i9506 and E330S use KNOX bootloader, thus you may expect some side effects after swapping kernel/system images. For best result i recommend to clean both kernel and system from KNOX.
I still use old 4.2.2 bootloader which is not infected by knox. With this bootloader you cannot use any stock 4.3 kernel. You have to compile kernel without TIMA authentification to be able to boot it with 4.2.2 bootloader.
Thus, i cannot tell you much info about stock kernels from 4.3 ROMs. Some users report about non-working WiFi if you flash stock i9506 kernel on E330S device. But you may flash kernel, system and cache from i9506 to E330S - it will boot at least.
So I've recently rooted and installed a custom rom on my phone for the first time with success. My phone is the T-Mobile Galaxy S3 N900T. I'm running C-Rom-KK-v7.1-20140622 which is based on 4.4.4 and it's great. I've been trying to find a custom kernel that I can load onto it to help increase the battery life, hence why I heard LK was really good for that, unfortunately every time I flash the kernel it just reboots to a black screen. The LED buttons will sometimes light up, but nothing else happens, and I'm forced to wipe and reinstall c-rom. I'm really looking forward to getting a custom kernel to work and any help would be appreciated.

Been a while since I scanned the N3 forum however, check that the ROM is compatible with the Kernel and If the Kernel does indeed run on the 900T - when I had my N3 T-Mo users used to have to flash a fix to boot N9005 kernels.
Hello,
I know dual boot and multirom! And I'm struggling a lot with multirom, can't get it to work... I can't find the "right" kernel, some files in the thread are dead and so on.. The thread seems kind of dead to me. I was trying for days now.
So is there somebody out there, who can provide us with working links / files and an short working instruction how we can boot different roms?
My device is D802. I don't care if my priamry ROM will be a Kitkat Stock or Resurrection Rom...
I'd be very grateful! Thank you!
Can somebody who really has an overview tell us if there is a way for multi boot on the G2 at all...
As I read on, I get the impression that it's not possible because of the locked bootloeader but then I don't understad why there was a thread about multirom... And I can't read pages of the multirom thread, it's too much
We need somebody with more experience here
Thanks again
I remember that someone talk about multiboot and say that lg g2 can boot only aosp ROM with another aosp or stock and another stock because of locked bootlader

ok, thx, ****ty news :/
Also found this, but as too often, no summary, understable instructions - so for only a little circle of devs themselves in the end. That's kind of bitter.
http://forum.xda-developers.com/lg-g2/general/multi-boot-dual-boot-stock-slim-t2993233
It says e.g. you have fo flash a modem and there's a link with many different modems. So if you are not really deep in it, it is hardly usable. Also it semms to me that you have to read the whole thing to have a clue, the fiest post isn't updated (probably -on first glance)
Too bad. But I'm sticking on this. I want the multi/dual boot.
hello,
i'm looking for a ROM, that everything works. Everywhere I read, this or that doesn't work.
I'm looking for something that isn't too old and everything works without a problem.
it is not necessary to have android 9 or 10.
Thank you in advance for your answers.
Someone?
I can't guarantee that every single thing will work but blackdiamond n8 is a fantastic rom. You can choose which bloatware apps you want and other settings

Then stay on stock rom its the best one that fits your criteria..
Also depends what you exactly need custom rom for.. you need often to sacrifice on somethings to get another ..
At this point.. if you are new to rooting and custom OS scenario, i recommend staying on stock.. because it is now more complex procedure and gives far more problems sometimes then it gives benefit. Imho the benefits of rooting/custom OSes are degrading slowly to the point where its just a useless hassle..
But ofcourse its everyone's choice.. you want to live on the edge by trying new OSes/new things/features you are free to do.. just make sure you know how to do everything safely, and backing up the vital data, like copying your nv data (the first thing after gaining su access), knowing the correct/safe procedure and please DON'T "ACCIDENTALLY" turn oem unlock off..
I personally recommend gaining su access by SYSYEM LESS methods plus magisk in order to avoid dm verity errors and encryption problems.. it also makes it less likely to mess with your nv data..
See alexndr's system less dev base and custom rom.. its based on stock 8.0 too (i think its all stock) and also stable too
https://forum.xda-developers.com/s7-edge/development/rom-dqd1-devbase-v4-1-multi-csc-safe-t3591647/
OR if you want to live on the edge.. backup your nv data and try custom roms like black diamonds, hyper rom, deluxe rom and any other which is being actively updated/supported.. try and find your taste on your own and report problems on their threads (every rom has their problems)
But i would either root stock "system lessly" or flash alexndr's custom systemless OS devbase
