AICP
Android Ice Cold Project
AICP is known by everyone as the "Ice Cold Project" that started on a Desire HD years ago (2012) and since then has evolved into a mature ROM with the BEST community that you can find!!!
Until Lollipop, the Rom has always been based on AOKP. Unfortunately, since AOKP stopped development (but made a comeback later), we changed our base to CM.
With the re-brand of CM to LineageOS (LAOS) we are now LAOS based with some tweaks from AOSP.
If there are any bugs, either we will sort them out or the LAOS team will if it concerns their code base. This rom isn't LAOS supported, so no need to report errors/bugs to them!!
Code:

* We are not responsible for bricked devices, dead SD cards,

* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at us for messing up your device, we will laugh at you. Hard & a lot.

FAQ:
Before using the ROM:
Q. Can I have an ETA for the next build?
A. Yes, just look in the OP to see if your device is built on a nightly or weekly schedule.
Q. Does this ROM support custom kernels?
A. No. You can still use them, but discussion should go in the thread of the respective kernel. We don't offer support for bugs you might encounter while using them!
Q. Why doesn't this ROM support Xposed?
A. Xposed is a hack that is geared towards AOSP, custom ROM's modify the framework a lot, so Xposed can cause a ton of issues on custom ROM's. Now it might work for you, however it is not to be discussed in this thread, and you should refrain from posting bug reports.
Q. Alright, but I still want to flash Xposed, so which version do I need to install?
A. You will need to use the version arm64/arm/whatever for SDK 27.
Flashing the ROM:
Q. What do I need to know before flashing?
A. Check the install instructions in the first post...
Q. Can the builds be dirty flashed over each other?
A. Yes, however make a nandroid backup first as there is a chance of getting a bootloop or encountering bugs. Also bugs may only be reported on a clean flash.
Q. How do I dirty flash builds?
A. Wipe the System, Cache and ART/Dalvik cache. Flash the ROM, GApps (only needed if you wipe the system), your preferred root solution and reboot. Or just use the OTA app to preform that task for you.
Q. How do I flash kernel builds?
A1. If it's a .img file, boot into TWRP and go to the install page in TWRP, in the bottom right corner select "install image", select the desired kernel, then select "boot", then swipe to flash, then go back to the install screen and install your root method again, if you don't want to loose root and reboot.
A2. If it's a flashable ZIP, you can flash it together with a ROM update or separately. Go to the install page in TWRP, choose the kernel zip (or add it to the flash queue right after the ROM zip). Then add your root method to the queue if you don't want to loose root. Now swipe to flash, and then reboot.
Using the ROM:
Q. How do I enable software buttons?
A. Go to Aicp Extras/Navigation bar, and enable it.
Q. I installed a bad theme and now I'm getting a bootloop, how do I fix it?
A. In TWRP, flash the substratum rescue zip that's in the substratum folder on the internal storage.
Q. I keep losing root with Magisk, how do I fix it?
A. Check this out. If that doesn't work for you, ask for help in this thread, read or ask in the Magisk thread on XDA or just re-flash Magisk!
Q. I'm having issues with WhatsApp, how do I fix it?
A. Read this
Q. Do I need to provide a logcat if I'm reporting a bug?
A. If you want it to be fixed faster (or at all) then yes, you should definitely provide a logcat. (Note: Please just link the logcat from your GDrive, Dropbox, etc. and do not post the content here. Thanks.
Q. How do I get a logcat, what type should I get and more questions that can conveniently be answered by my pre-determined answer?
A1. Read this thoroughly. Also, here's a good app for getting logs: https://play.google.com/store/apps/details?id=com.tortel.syslog (Root needed).
A2. If you are already rooted, you can use the built-in feature to make a logcat and provide that. Just look into the others section in the AICP Extras main page.
The ROM should contain everything you need to enjoy Android Oreo. You don't need to install any Add-on's, simply download the latest ROM, GApps, flash it and go!
If you want the device to run the ROM "rooted", you can flash a root solution of your choice after the ROM Zipfile.
It is STRONGLY recommended to fully wipe your device before flashing and please avoid restoring system apps and system data with Titanium Backup as this can cause stability issues that are very hard to debug.
If you believe you know what you're doing - then fine, go ahead, but please don't complain if you experience any strange behavior.
How to flash:
(Again: Don't do it if you don't know it!)
1. Download the ROM and GApps and transfer them to your device.
2. Boot to recovery (TWRP recommended).
3. Wipe the System, Cache, Data and ART/Dalvik cache.
4. Flash the ROM Zipfile.
5. Flash the GApps (optional, needed for e.g. Google Playstore to work).
6. Flash the root solution of your choice (optional).
7. Reboot your device.
The ROM has GApps persistence in between dirty flashes, so you only have to flash them once!
The root solution should be flashed together with every OTA update (= ROM Update)
Currently Supported Root Solutions:
Magisk stable
Magisk versions higher than 14.0 doesn't require flash on every dirty flash depending on the device, some devices need you to flash it every time, unless your maintainer says otherwise it should be fine
KERNEL:
The kernel in this ROM follows LAOS source with custom additions.
PREREQUISITE FOR OTA:
To be able to flash using the built-in OTA app, TWRP recovery is needed.
You can still use the LAOS recovery and OTA app, but you will need to download the zip file and flash it manually from within your recovery. The Zipfile gets saved in the "aicp_ota" folder on your internal storage.
Please be sure that you are on the latest TWRP recovery. Keep in mind that this could also be an unofficial version!

Since I don't own a SM-T555, I can't tell you whether it boots or not. This build is designed for the Wifi-only variant, so your tablet definitely won't support LTE/telephony. Maybe I'll publish a SM-T555 build in the future.

I don't really care about ril but it just doesn't boot. Like the other roms and i just can't find the problem. Lineage os 14.1 should boot on t555 too but without ril and it ij stuck in the boot logo refusing to boot into /system.

Have you fully wiped the cache & data partition?
What does "it doesn't boot" mean:
Does it pass the samsung splash screen & shows a stucking boot animation?
Are there tombstones in the data/tombstones folder present?

I guess you know what you're doing and have enabled OEM unlocking. When TWRP is able to boot, the rom is probably not compatible with the SM-T555. I can message you when I've compiled a SM-T555 testversion. Only if you would like to help me making the SM-T555 compatible.

Hi all,
I tested the ROM on SM-T550 and it boots quiet well.
Initial google (nano opengapps) setup was broken for me, but the setup
via "Google app" and my phone worked.
Another thing is that when installing a browser it
crashes right after starting it.
Opera says that I have no space free
Chrome says something like an unexpected error.
Buildin browser just appears short and closes immediately.
The game little wars and Netflix app shows the same behaviour.
So right now I can't use the ROM but I am very Happy that this device is not abandoned!
Thank you for your work and if I can help testing, just drop me a line.

I have SM-T550
Its great ROM, but.. Problem, has error browser, for example: I can't open Google chrome, opera, ... Pls fix? You are the best! ??

---

Ok so apparently it boots but the screen is always black. I just found a screenshot i've taken accidentally after i flashed the rom and it seems to boot.

Thanks for your report. The latest build should work.

My Model: SM-T550
I have one problem... The ROM is great working with all browser (Google Chrome, Opera, ...) Very Good.
But... Please you read.
- It's very laggy the security (for example: PIN, password and Sequence). I'm ready PIN, it's fine.
When my tablet is lock PIN (Off). I'm watching TV or other. My tablet lets off 1 hour. After, I go my tablet open "On" it's very laggy and PIN too, all..
I hope you understanding? I'm a deaf, sorry!

---

I'm fighting against selinux right now. I'll update the build soon, thanks for your hint.

---

I think I found why the screen is not working on t555: might be because of a problem in the kernel. More precise the dt. You can use the kernel from the stock firmware as base to fix this. Also for the ril take look at samsung galaxy j5 2015/2016 sources. They have the same chip as t555/t550. Especially the 2016 version as it have almost the same base firmware (7.1.1).

Maybe you should build it on your own. The entire building process is basically very simple.
It's actually quite easy to port it from the gt510wifi device tree. The kernel sources are available and the only thing to worry about is the RIL.
