[C6903] - cant run new NOUGAT custom roms - bootanimation 2-3 sec and phone turns off

At the beginning, please forgive me the quality of my English.
Me and other friends using c6903 have posted on the forum about trouble with running Nougat ROMs:
- [ROM][7.1.X][27/07/17][STOCK-CAMERA][3.4 KERNEL][TESTING] LineageOS 14.1 - UNOFFICIAL
- [ROM] [7.1.2] [OMS] [OFFICIAL] [Honami] Resurrection Remix Nougat v5.8.3 [01/08/2017]
- [ROM] [7.1.2] [Substratum/OMS] [UNOFFICIAL] [Honami] Android Ice Cold Project 12.1
For example LinageOS 14.1.
I flashed build from 11/07 without any problems.
Everythings worked fine, but when i try to flash newest build I encountered a big problem.
Bootanimation continues 2-3 sec. and phone turn off [check plz video].
Then only the launch button was active.
Everything I do exactly the same as in 11/07 build.
Why rom can't run?
The situation applies to all the above versions.
Resurrection Remix Nougat from 28/06 booted fine too.
Newer versions not...
One of friends - MIcHiJK - suggested that this could be a problem with changing the screen for "fake".
Me and him changed screens probably for counterfeiting.
Maybe someone else did it and have this problem?
....but why build from 11/07 (LinageOS), 26/08 (RR) and 20/06 (ACIP) booted without any problems?? In my case change screen was earlier.
What have I done so far to solve the problem.
- used TWRP 3.0.0 and 3.0.2
- Always full wiped (a few times format internal storage using twrp too)
- flashed roms when using Cyanogenmod 12.1
- flashed roms when using stock .236
- restored software using EMMa and Flashtool, then root (kingroot), flashed twrp by fastboot, full wipe, flash rom - without result
- used others kernels referenced by creators roms (flashed after installation rom).
Nothing worked.
I know I'm not alone. Many guys have problem like me.
Is anyone able to give a solution?
May God bless guy which will solve our problems!

Hello to all ppl which had this problem.
Since I replace my broken original xperia z1 Display, I wasn´t able to boot any of the new Nougat rom releases.
I solved this problem with a new Kernel.
Super Lamic Posted this Kernel to test the Battery Life but with this Kernel the problem was solved and I was able to run the new Releases on my fake Display.
Kernel Link: https://mega.nz/#!RN1nFYRT!546WMDdM2ToJEeZlleKTjS-TdR54rkYiOGKUDDWQ-t0
Install new LineageOS build on your xperia z1 with TWRP 3.1 (with 3.0 it wasnt able to install the boot.img).
Before you reboot select images, boot and flash the boot.img.
Then the new build should run without problems.
On other roms like Resurrection Remix it endet in invinite boot so I was just able to run normal Lineage.
I hope it helped someone. Im still interested what the devs changed that causes this problem. And I hope there will be improvments in future that this problem wont happen anymore.

same problem for me like OP. Would be interesting whats the reason for this behaviour that some nougat roms don't run on phones with replaced display. for me some still run, but then i have the problem that recovery is not available.

For those wo will flash AICP maybe this solution will work in RR too.
In normal Lineage it worked when i flashed cm12.1 Nouagt Kernel after flashing LOS 14.1.
But for RR or AICP it ended in infinite boot. Here is how I managed to get it work.
1. Download AICP (Latest Version [2017/08/01]) then download AICP (Version 2017/06/20).
2. Delete 'boot.img' from the Latest Version zip and put the 'boot.img' from the older relase into the Latest
3. Boot into TWRP 3.1 or 3.0, Wipe all and flash your Latest AICP zip with the older boot.img.
4. Boot phone. The z1 will show you just the Sony Logo. I waited some Minutes and powered off with power + volume up.
5. Connect phone in fastboot mode on PC and flashed cm12.1 Nougat Kernel.
6. Type 'Fastboot Reboot', the phone Turns on with the newer Boot screen where xperia stands on the bottom. You will finally see AICP Boot Animation and after some time rom boots.

Just Install Recovery via Fastboot. If you dont know how to do this you need to set up android sdk. You will find many tutorials in the internet.

How did you installed the rom?
From which rom you came and which recovery did you used and how did you installed the recover?

different ways, but mostly with my standard custom-rom Tesla which is on Android 5.1.1. TWRP is on 3.1 which i install via cmd (fastboot flash recovery) cause build in recovery of tesla is broken.
Or i go over latest stock with dualrecovery, flash boot.img of the custom-rom (wich work) and then flash rom. but still recovery is gone after that.

@Aaskereija
I can tell you how I installed. I never lost my recovery. I came from xproject rom and I had nuts dual recovery. I flashed via fastboot advanced kernel, rebooted directly into inbuild TWRP 3.1, wiped all and flashed nougat rom. I had no recover so I flashed via fastboot official TWRP 3.0 and now I have a recovery. Since I installed TWRP one Time i never done it again. Everytime I flash a new rom it's still there. Maybe you try some different ways to install a nougat rom cuz it should work we all have the same device. Another question. Can you give me link to TWRP 3.1 for honami. I can't find TWRP 3.1 for z1 I used it just with advanced kernel. I just can find official TWRP on the internet witch is outdated

Guys, you don't have to create threads for this. I'll have an aftermarket display too, so I'll be forced to fix it anyway. And I have an idea what can be wrong...

Android Sdk put twrp.img in platform tools folder then open CMD in this foder, fastboot flash recovery TWRP.img.
I asked about twrp cuz in advanced kernel is TWRP 3.1 inbuild but I can't find just the twrp 3.1 IMG without kernel. Strange.

can NOT install magisk v16.0 on lineage 14.1 ?

hi
can not install magisk 16.0 on lineage 14.1 for i9100 ?
how fix this ERROR ?

Try this (I can not assure you that this will work, since I don't own your device):
1 - Open your LineageOS build zip with some file manager.
2 - Extract the "boot.img" file to somewhere else.
3 - Now go to twrp, tap install, then install image, find and flash the "boot.img" you just extracted.
4 - Don't reboot yet, go back and try to flash magisk, then reboot if you succeed.
It worked with me once. Worth a try.

Have you tried the beta version already?:

The S II is quite an old device, and I believe it never got officially updated past Android KitKat, right? Might be why...
Even though the OS is updated by a custom ROM, the boot image may lack the necessary parts for Magisk to patch. At least, that's what your log shows...
You might get more help if you ask around in your device's forum.
Edit: Yup... https://forum.xda-developers.com/showpost.php?p=76705332&postcount=25084

Redmi 4X: TWRP, LineageOS, Gapps (Cannot update ROM) (nightly) *error*

Hi everyone,
I'm new here though but am a Xiaomi user from the beggining of Xiaomi into devices with Redmi Note 3G Enhanced.
Currently, I own a Redmi 4X and I would like your expert lights please. I've flashed the latest twrp from twrp.me for my santoni device. Then flashed the latest build from LineageOS Official source + Gapps before booting up for first time. Everything was working perfectly until I decided to flash the latest update of LineageOS as I've seen in my updater it was released. So, I downloaded it through the updater and tried to flash it...
I came up with this "Failed to unmount /system (device or resource busy)" after that re-booted to LineageOS and everything was messed up with Google Services & Apps etc. Then I went back to twrp recovery and tried to flash again the rom but I was still getting that message so I understood something am doing wrong. Also santoni has dm-verity enabled which I know something about but just an info. I really wanna stick with LineageOS on my Redmi 4X forever but I'm afraid to flash it again. I've flashed MIUI 10 Beta by fastboot but now I wanna go back to LineageOS forever (addicted).
My only problem is: After successfuly flashing LineageOS and Gapps, I cannot apply (flash) updates to update the ROM to the latest nightly build due to this error above.
Kind regards,
peryson

Try with different recovery. For example with this

Instead of trying an unofficial recovery, do I have an option to unmount system manually before flashing through Official TWRP?

You can download latest Lineage OS build and dirty flash it (without any wipes) (so you can unmout system parition). And I don't see any issue in using unoffical twrp.

I also have experienced same error once during upgrade "failed to unmount /system"
Eventually I wiped everything and did clean flash from scratch. This is really annoying issue and demonstrates that upgrade system is not 100% reliable for some reason.
I'm not sure however is it Lineage or twrp issue.

Can't install Oreo on my C6603 device, need help asap.

Hey all
This is my first post on XDA and i actually created this account so i can get ur help guys
Im trying to install android Oreo on my device
I tried resurrection remix rom and lineage os latest version but i get the same error everytime.
I flash the rom successfully but after rebooting it takes too long at the loading screen (rr logo or linage logo) then suddenly reboots and enter the twrp screen automatically without pressing any buttons
I used many different versions of twrp starting from 3.0.0 and all upcoming versions
I tried installing the rom with these two methods
1- flashing the rom zip from the twrp recovery
2-flashing it using the adb sideload
Android Nougat works well with my phone, im currently using linage os latest version of Nougat
The problem seems to happen only with Oreo ?
I really need help installing this rom

I've been waiting so long for a reply
Can anyone help me? ?

Lineage OS stuck at TWRP screen

Hello,
I am new to the world of custom ROMs, I have a huawei mediapad T5. I followed the guide and successfully rooted my device. then I installed TWRP from this link:
https://forum.xda-developers.com/showpost.php?do=showpost&p=76362629
I struggled to flash lineageos 16 on my device, after couple of hours, I found the installation guide from openkirin, that mentioned they don't support TWRP. but as I had already flashed my device with TWRP, I had no backup for stock recovery image. I tried to flash it anyway as mentioned in the openkirin site.
but now it stuck at TWRP screen. I am not sure how can I remove twrp completely from my mediapad t5.
After messing around I managed to boot into eRecovery from huawei, where I got option to download the stock firmware. that saved my day.
But I really want to flash it with LineageOS 16. I am not sure what can be done about twrp. Is there any way to remove it from my Mediapad, or is there any guide to install Open Kirin's LineageOS image onto my device along with TWRP?
Please let me know.
#Update
I managed to install Lineage OS onto my Mediapad T5. But I am afraid, I didn't like it much. It is not optimized for the tablet. There're unnecessary apps like Phone App, Messaging App etc. I only got Wifi version. Plus it has issues with Audio Output.
I am reverting back to stock ROM for now, Until better ROM is available from OpenKirin.
