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 evolved into a mature ROM with the BEST community 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 when it comes to hardware, drivers and some features.
With the rebrand of CM to LineageOS (LAOS) we are now actually 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 or bugs to them!!
Code:
#include <std_disclaimer.h>
/*
* Your warranty is now void.
*
* We are not responsible for bricked devices, dead SD cards,
* thermonuclear war or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* 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 build on a nightly or weekly schedule.
Q. Does this ROM support custom kernels?
A. No. You can still use them (as long as they are LOS based), but discussion should go in the thread of the respective kernel. We don't offer support for bugs you might encounter 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 for SDK 25.
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 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 System, Cache and ART/Dalvik cache. Flash the ROM, your preferred root solution and reboot. Or you might just use the OTA app to preform that task for you.
Q. How do I flash kernel builds?
A1. 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 then reboot.
A2. LOS based kernels sometimes come as a flashable ZIP file too. You can flash them 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, clear Cache & ART/Dalvik cache and then reboot.
Using the ROM:
Q. How do I enable software buttons?
A. Settings -> Navigation -> Enable navigation bar. The bar can be configured separately in its settings.
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 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 flash Magisk again!
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
A2. If you are already rooted, you can use the built-in feature to make a logcat and provide that. Just look into the root section in the AICP Extras menu.​
​The ROM should contain everything you need to enjoy Android Nougat. You don't need to install any Add-Ons, 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 if possible 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 system, Cache, data and ART/Dalvik cache
4. Flash ROM Zipfile
5. Flash/Install GApps (optional, needed for e.g. Google Playstore to work)
6. Flash/Install the root solution of choice (optional)
7. Reboot to system
The ROM has GApps persistance 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)!
Supported root solutions:​Magisk v13.x
SuperSU - stable and beta available (Site by CCMT that took over the the marketing from chainfire)
SuperSU - direct download link for the latest SuperSU directly from the dev (chainfire)
Lineage SU-addon (check your needed version: 14.1 arm or arm64) -> the removal zip is available here too.
KERNEL:
The kernel in this ROM follows LAOS source with custom additions from AOSP.
PREREQUISITE FOR OTA:​To be able to flash using the buildin OTA app that needs TWRP recovery installed to work.
You can still use LAOS recovery and OTA app, but you will need to download the zip file and flash it manually from within your recovery. Zip gets saved in the "AICP_ota" folder on your internal storage.
Please be sure that you are on the latest TWRP recovery.

Does it fully work? Any issues?

I,m waiting one x722, when it arrives I Will install this ROM, I had very good feelings in the past with aicp, I usually used in Xiaomi mi4c and worked perfectly.
Thanks for support x722...

---

Thanks for sharing Murat1150
Is there OTA UPADATE AVAILABILITY for this ROM?
The changelog of this ROM indicates that it has been built for the X720;Not X722.....
Another issue is that the available nightlies for this rom in the link you provide are for X720 as WELL.
Can we safely flash these nightlies on X720?

Unfortunately there are no official support for the x722.
What i have done is compiling from source with modifications to make it work on x722.
There are no nighties nor ota update for the rom just if i decide to build again.
This rom is for x722, i flashed it on mine and it is working well and doesnt break anything. But still you are responsible what you do.
I got the template for this post from aicp github, thats the reason why there are some reference to x720.
I build the rom for my personal use but decided to share it with others as building from source can be a challenge.

first thanks

I'm interested to try this ROM, can you please list some of the minor bugs that you find?

---

The only major issue is Dolby atmos malfunction.

---

Sometime this Nougat Lineage/Aicp rom have problem when make phone call, so make sure to test the function.
I running Aicp Nougat on my X720 its quite good for performance/battery/sound is good too lately I switch for Crazy kernel due to phone freez sometime with stock kernel.

---

Murat - again thank you for amazing work!
I had a question - what rom you suggest to use, and what
rom you will continue to develop more?

---

I have a problem in TWRP when I try to instal the room, it says that my device is a le_zl1 and the room is for le_zl0. What can I do?

---

Could someone test the battery life on this rom?
Is it any chance to have 7-8h sot like in stock rom?

---

@Skune
You need to edit rom installer script and change to zl0 (zero).
Google for details

---

What happens?
I have a different result every time
Max - 138 900 but mainly 70k-100k

Edit update-script in rom. Zip?

---

I'm bit rusty now but it should go like this:
Open rom zip with 7zip
Navigate to /META-INF/com/google/android/updater-script
Drag the script to desktop (don't close 7zip)
Open it there with notepad++
Delete text, starting from "assert ....... till the semicolon ( of the last getprop command). - check this, not sure 100%
Or - you can just rename zl1 to zl0 (zero)
Save the script and move it back to where it was in the rom
Close 7zip
Flash the rom

i have yet to test them myself but my favourites are lineageos and aicp
i dont develop them i just build them for x722
some are easier to build (lineage & aicp) and some are a pain in the ass (aospx)
i hope in the future there will be support for zl0 also and not only zl1
until then we have to build roms for zl0 ourselves

---

I've been testing it for last 24 hours. Pretty good overall, speacially in customization, but i'm feeling that the performance it is not as well as paranoid rom. Maybe the governor can be change? any advice for what?
Thank you
