Z1c Nougat Roms

1. AOSP, by @freexperia -
https://www.androidfilehost.com/?a=show&w=files&flid=17562
Tested 2/27 AOSP build. Seems smooth and stable overall. Only browser is some kind of experimental one that doesn't work too well, or at least you need to spend more time getting used to it than I was willing to. Camera works, but is as good as any other N camera at this point, (bad).
2. AOSP and Lineage, (CM), 14, micro-g patched, by @MSe1969 - https://www.androidfilehost.com/?a=show&w=files&flid=155737 - haven't tried yet. I mistakenly linked it to fxp until I just now noticed it. Will try soon...
3. AICP - https://forum.xda-developers.com/so...lopment/rom-aicp-11-0-mm-6-0-1-amami-t3428288
Excellent rom, regular updates, and lots of customization. Some people have posted about dropped calls in recent builds, but haven't heard of other issues. Magisk integrated. If someone can figure out how to get a good camera, you could hardly ask for more.
4. AOSP by @CLINTZ9 - https://forum.xda-developers.com/sony-xperia-z1-compact/orig-development/aosp-t3317511
I haven't been able to get it to boot, (error in twrp). OP says to ignore error and flash, but it won't flash anything for me. I think others have, though, so maybe just something I'm missing. Let me know.
5. LOS by micha-btz - https://www.androidfilehost.com/?w=files&flid=153937
Just stumbled across it, and my BL is currently re-locked, so plan on trying soon...
Update - tried today and works well, everything seemed to function. Bad camera as usual, and I couldn't get back into recovery for some reason. I had to flash a different kernel first...
6. CM14/LOS builds by @derf elot https://www.androidfilehost.com/?w=files&flid=41716
7. AOSP builds by SonyAOSP team, (@davidteri91) - https://www.androidfilehost.com/?a=show&w=files&flid=187966
8. LOS 14 by @Hazou - https://forum.xda-developers.com/so...opment/rom-unofficial-lineageos-14-1-t3636822
Haven't tried yet. Let us know...
9. LOS 14 by munjeni - https://forum.xda-developers.com/sony-xperia-z1-compact/development/rom-t3657384 Probably the best yet. Excellent camera. Some have had random reboots on latest build, but maybe fixed with this - http://munjeni.myiphost.com/system.rar
10. Sudamod by @maz-1 - https://forum.xda-developers.com/sony-xperia-z1-compact/development/rom-sudamod-3-1-t3666092
Testing now, LOS-based with some custom tweaks. Fast and smooth, fully working. Op says camera is good, even though 3.1 kernel, pictures look OK so far, going to test more in the light. Very nice ROM.
11. M-ROM port by @dmgZero - https://forum.xda-developers.com/sony-xperia-z1-compact/development/m-rom-v2-4-0-t3711381
Stock Nougat style and apps on custom (Carbon) rom. Very nice. Original dev seems to have abandoned xda, but rom has been popular on several devices up to v2.3.1 (I use it on Z3c [https://forum.xda-developers.com/z3-compact/development/rom-los-xperia-ui-z3c-t3654894]). 2.4 was never posted on xda, AFAIK, but posted on a Chinese site called 0z4l, or something, but not possible to download without registration, and I couldn't get successful registration. dmgZero has modded it, apparently. I haven't tried it, since I'm using Z3c at the moment...
BTW - seems to be some degree of controversy around the security of latest version. Check device threads and judge for yourself.
12. Flyme OS by @dmgZero - https://forum.xda-developers.com/sony-xperia-z1-compact/development/m-rom-z1cflyme6-8-1-22r-t3742581 I'm mainly on Xc now, so check thread for reports...

to those that have tried the FXP 7.0 (nougat) rom:
did you encounter any other problems besides the non working camera?

Tried out AICP 10/3. Looks good, runs good, no camera...

hi good day. I'm pretty new to flashing
I managed to install some custom rom and gapps with TWRP.
so I'm now a bit more confident in installing new roms
there's so many custom roms, I don't know which to choose. I need something not bloated, fast, and fully working camera. any help is greatly appreciated.
(or maybe I just should root the stock rom and uninstall bloated apps ?)

For the short answer, he's probably right - Jaguar Is excellent. However, there are now very good roms for this phone in kk, lp, mm, and now n, so there's lots to try. If stability and camera are your main priorities, go with stock-based, or Jaguar. Personally, I don't feel debloating is necessary, if you use an app-management app, like AFwall, or 3C toolbox.

thanks guys !! i shall try jaguar !

Jaguar has all the security updates included which even some Nougat Roms does not have.

Hi there,
I made a CM14.1 build for amami for you to try, based on the sources of sonyxperiadev, SonyCM and SonyAosp. So a big thank you is in order to everyone involved in these projects. I only modified the sonyxperiadev amami sources to work with this build, set SELinux to enforced and removed the Gello browser from the build (there are more updated derivatives on the Play Store anyway).
I have run it for a little bit, and noticed the following bugs so far:
- deepsleep not working when wifi is on (I think)
- camera sometimes force closes, sometimes works (known memory leak bug I think, cam is work in progress)
- lots of CM stuff is not there yet, including themes (remember, CM14.1 is a work in progress)
- ?
To install it, you most likely need real recovery with TWRP3. It includes the new Sony init, so reboot to recovery from ROM works. I'm currently using it with latest OpenGapps and SuperSU, which both seem to work fine as well.
The Z1C is currently my secondary phone, but once it becomes more stable and feature-rich and once Xposed is available for 7.1 (fingers crossed), I will probably also build for the Z3C. Unless we get to see some official CM love again of course.

random reboots

idk if posted some same thread but my problem is my phone suddenly reboots.
screen went off, twice vibration, then went to samsung galaxy s5 logo.
current setup: android 6.0.1 running no limits rom. all stock
sometimes it reboots then it is stock on the bootloader. i need to remove the battery and turn it on manually. using bootloader and modem of the latest recommended bootloader from the no limits rom.
(it also random reboots on stock firmware using spain which i downloaded from sam mobile firmwares)
is this a hardware issue?
edit: what i did was i upgraded my stock rom from 5.0.1 russia to 6.0.1 spain, does this affect anything? should i stick with russia?

Do your phone gets too hot then?

I know what's going on I think. Something modified your kernel or something in the ROM is unstable. I had one that did that same thing when I used the camera. You need a better ROM. I recommend ressurection remix 5.8.3 nougat 7.1.2. No reason to be on marshmallow. And get this kernel. It fixed the camera issue and improves battery life. It's a unified klte rom.

That does not guarantee there's no bugs in your phone. Have you ever flashed a ROM or anything to your device?

Upgrade to a nougat ROM. It uses the same bootloader of mm so you only need to flash a ROM. Get ressurection remix or lineage is 14.1. Nougat fixes a lot of bugs and security issues. And xtrestolite isn't the most stable ROM. I had it in my s4.
---------- Post added at 06:47 AM ---------- Previous post was at 06:45 AM ----------
And then if you use rr get the kernel I showed you and flash that too. Please note these Roms don't come with gapps. Google open gapps and it comes up. You want arm 7.0 or 7.1. Stock if you don't mind waiting a while for it to download. I get nano to save time as it still installs the framework and playstore. It saves space and if you want something it didn't install play store will have it anyway.

so you mean cyanogenmod?

Cyanogen mod is now lineage os team. Don't use cyanogen. Get lineage 14.1

If none of the software fixes work, it's your battery. Personal experiance from my S3 Mini and my S5. Don't rage over it going nuts (been there, done that) but just get a new battery.

Sleep of death in all Nougat ROMs

The global trouble with all nougat firmware
Hi guys. I amn't alone, I met 10-15 users at 4pda with such problem.
We have the bug at all nougat roms by any devs with different trees...
The sleep of death.
Personally I notice it after/during mobile internet using, but I'm not sure. For long time at home(for a week, for example) with WiFi I have no troubles. But if I am anywhere without WiFi and use 3g(don't have LTE in my country), my phone "sleeps" for some times during just one day... It isn't powered off as it's needed 10-15 seconds of button pressing to turn it on at least.
As the ROM and developer has no meaning I guess that here are the errors in the kernel. @fir3walk says that here are many bugs in our nougat tree and perhaps the trouble is involved in last_dmesg... Or some system force stopes, dozes work improperly.
Not many users have this trouble but it exists an a fact. So it would be great to detect an error and try to fix it. Perhaps not in nougat, at least in new Oreo(I haven't tried it yet so no information about this bug there). We have many ROMs, they are updated for some times a week, new roms are rolling out... But the bug stays still.
If someone else has such problem, write here. Perhaps somebody has any ideas and together we will be able to find solution...
So, all the devs who can detect an error, write us... Any tests, information, logs, etc.
P.S. By the way it is impossible to write logs of powering off(deep sleeping) via logcat or another's. If I run the logging I have no "sleepOFdeath".
It is really global trouble so let's try to fix it together.

I'm sorry for your trouble.
Lets start by figuring out which device is in question
I have a 3s prime and never saw this issue.
So do you have a 3s or 3x or 3s prime?

Hello OP, can i ask if you installed that MIUI Ported ROM based in nougat? Because when i installed it (twice) y faced this issue in every rom that i flashed afterwards, then decided to clean-flash miui fastboot rom and the problem was solved.
Maybe that's your problem.

i face it in rr rom but no in dnd rom

Guys did anyone here with the sod, flash global stable/developer in edl mode?

Hello. No, I didn't try miui based on nougat.
But other users say that they notice such trouble at miui(7 android) as well.
So it isn't the cause...

Will try to flash via miflash, as I faced no problems before this SOD at 7.1.2. Always flashed my phone via twrp.
By the way, guys, my 3s sleeps well on nougat, but it isn't econom in active mod.
For example, I have made a record at our device at 6.0.1 version - 17.5 hours of screen. Nougat isn't so optimized by now... 10-11 as maximum.

Wi-Fi does not work on LineageOS 16.0 (Pie 9)

Hi guys,
Everything was working great with LineageOS 15.1 (Android 8.1), but they have discontinued the support for this version and switched to 16.0, and a FOTA update of Lineage from 15 to 16 isn't possible, so I had to download the zip manually, and flashed it using TWRP, around the end of April. Since then the Wi-Fi does not work.
I should explain what this "does not work" mean: I turn it on (either from the pull-down curtain, or from the Settings -> Network -> Wi-Fi menu), it pretends to switch on for 1-2 seconds, and then the switch turns off by itself, so it doesn't even have time to scan the available networks.
I have tried to burn a newer image again, around the beginning of May, but it didn't fix the Wi-Fi problem. I was googling a lot, but seems like nobody reports such a problem.
Any ideas how to fix it, other than going back to Android 8.1? Preferably I'd like to stay with LOS, but if I have no choice, I can consider moving to RR, or AOSP Extended or whatever.
Thanks!

I think its a boot.img problem. I have seen this error in stock too. The wifi/bluetooth used to turn off immediately after i turned them on and the error was because i flashed the wrong boot.img . If i were you i would clean flash the rom again

What do you mean by "wrong boot.img"? I don't flash any boot.img separately, I just flash the whole LineageOS rom (and then Gapps) from TWRP. Should I flash anything else? I don't think so...
Well, in my case at least the Bluetooth works properly (with both headphones and smart watch).

SOLVED!
Surprisingly, the problem seems to be solved now.
After flashing lineage-16.0-20190426 and later lineage-16.0-20190530 versions, where the Wi-Fi didn't work - today I have flashed lineage-16.0-20190704, and guess what? It is back now!
Thought it should be important to update the thread here.

You mean, even if I upgrade from Lineage 15.1 to 16 I need to flash the stock rom first? Why?
BTW I saw some reports on Wi-Fi problem while going back from custom to stock rom too, and there was some patch suggested to fix it.

Because its a prerequisite on Lineage 16, it depends on parts of stock Pie rom being installed.
The LO16 thread also listed a migration step if you didn't flash the stock Pie rom beforehand.

Its on the xda thread, not on the lineageos website.
Xiaomi made some changes during the upgrade from Oreo->Pie and introduced ARB. Now you cannot downgrade back to Oreo easily. Just flashing back to Oreo(stock or custom rom) will cause the phone to bootloop. For the same reason your phone probably faced issues when you flashed (Pie) LO16 without the Pie firmware.

Well, I did not try to downgrade from Pie to Oreo. All I tried to do was an upgrade from LOS 15.1 to LOS 16 (15.1 worked excellent). And I had no idea I needed to flash the stock rom in between, so I just flashed 16 over 15.1, without wiping the data partition (only wiped dalvik cache).
Can you please point me to the XDA thread you mention, where it says I had to flash the stock rom first?
Anyway, since everything works OK now (or, at least, I don't find any malfunctioning, probably except for the native camera app, so I use an external app), I don't think I should play around with it again, right?

Some parts of the firmware might not be overwritten by LOS/stock depending on the version. The original LO16 used Oreo firmware iirc. The thread is not hard to find, just look for it.

Has anyone managed to get any custom ROM to work on a SM-A405FN/DS ?

Hello !
Has anyone actually managed to get any custom ROM to work on a Samsung Galaxy A40 SM-A405FN/DS ?
Mine is currently running the current latest stock ROM (SM-A405FN_2_20211030045838_jg43vcqbiw_fac) downloaded with Frija and I managed to install TWRP from here : https://forum.xda-developers.com/t/recovery-a40-teamwinrecoveryproject-3-6-x-unofficial.4364575/
However, ANY custom ROM that I try to install :
https://forum.xda-developers.com/t/a11-r-arm64-a40-lineageos-18-1-unofficial-by-kevios12.4335409/
https://sourceforge.net/projects/eurekaroms/files/Samsung/A40/R/lineage/
GSI
maybe others that I forgot
will either bootloop or end up with a black screen.
Looking at the following threads, I'm starting to wonder if the SM-A405FN/DS is custom-ROM-compatible at all ?
https://forum.xda-developers.com/t/help-my-a405fn-wont-boot-any-custom-rom.4337041/
https://forum.xda-developers.com/t/samsung-a40-black-screen.4354421/
https://forum.xda-developers.com/t/galaxy-a40-infinite-loop-impossible-to-turn-on.4337343/

Im running CrDroid 7.13 without any issues with root and gapps. Many custom roms bootloop because of your newer firmware with Bit/SW REV.
Security Patch Lvl. being 4 and those custom rom were built on the older firmware with probably patch level 3. I had installed DotOS fan edition fully working like a year ago, then I tried some new custom roms, which somehow broke my system so the system couldnt start up even after reflashing original boot image, so I reflashed to the newest firmware which was working, then I tried flashing older one and it wouldnt boot, it just shows black screen with error bit/sw 3 boot 4. So you have to flah roms, whose are built on the newer bit level to boot up, the best is CrDroid and now the newest ALT-F4 version 0.0.3 from this forum: https://forum.xda-developers.com/t/rom-oneui-3-1-a40-alt-f4-v0-0-1-updated-2021-12-18.4373813/
I tried it myself and it is the best for this phone, it is fully debloated and pre-rooted stock rom. I also tried CrDroid 8x, everything works for me, but it fells slow and the ram is almost maxed out. I also recommend upgrading to this TWRP: https://forum.xda-developers.com/t/recovery-official-twrp-for-galaxy-a40-a405fn.4025587/
The unofficial twrps had some bugs for me. I hope this helps and happy flashing!

THANK YOU for your comprehensive reply !! I'll give ALT-F4 a try as soon as I can !

Good luck!

Well, luck has not been enough: after updating TWRP to the official version, I tried yesterday to install ALT-F4 0.0.3 but got the exact same result: black screen, need to reflash the stock ROM to make it boot (even to recovery !!) again.
Would you have any other idea ?
EDIT:
I actually tried crDroid in the past, to no avail either.
