Hello, I can't install the rom, I have the lineageos logo that appears and after 30 seconds it comes back to TWRP. I did Wipe Data/Cache/System/Vendor

Thx
You might need to format data to boot into OS. IF you are not particular about encryption then flash dfe and it will boot.

LineageOS is a free, community built, aftermarket firmware distribution of Android 11, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.


Information:
  • This is an OSS vendor built rom.
  • Based on the latest Android Security Patch
  • Latest LineageOS changes according to the ROM date release
  • Stability and performance improvements
  • Safetynet passes out of box

Known issues:
  • None. You found one? Please report it here by providing a description with a log or a video if necessary.

Installation Instructions :

Assuming you have an unlocked bootloader, a recovery installed and the ROM zip:
  • Go to recovery
  • Wipe Data/Cache/System/Vendor
  • Flash the ROM
  • Flash DFE (optional step if you are not encrypted)
  • Reboot
NOTE: I always recommend following these steps. Also there's no need to flash any kind of MIUI Vendor.

One suggestion. Please put OSS in the title since the Miui vendor based LOS is also called Unofficial Lineage OS. It would be easier for people to identify.

After a day of use everything seems very stable - no crashes, good battery, etc.
The only issue I have found is that earpiece volume seems very low even when set to max. This is for all apps (Phone, WhatsApp, signal, etc).

Could you add a Quick Tile for switching mobile data SIM cards?

After using it for a few days, I didn't find any obvious problems, very smooth, battery life is also good.

I turned from another LOS rom. I used it for more than a year. From my experience, these two LOS rom both good, I am very grateful for the contribution of each own developer, I just want to use OSS. so I choose this one, I really don't like MiUi's things, even it is just vendor.

I know that developer has already released several releases on GitHub, so I think it should be the choice of my daily use, it is really good! thank you again!

I found a problem with the location today.

Given the application location permission, and enable the location in the system setting, but still unable to get the location. At the same time, use the GPS Test application to view GPS information, and find only one satellite and the signal is very weak. another mobile phone can search for more than 20 satellites at the same place and time, and I am sure before flash this rom, the phone can also successfully get location and search so many GPS satellite signal.

tried Google Maps, Google Earth, GPS status, GPS Test, clear cache, reboot phone a few times, or update the A-GPS data, still not work.


Very weird, can't get the location yesterday. tried any way I could know, but everything is normal today ...

When flashing just the ROM without Gapps, it boots for 30 seconds and then enters the recovery, whereas it boots normally with Gapps (tested with nikgapps core).

Has anyone flashed just the ROM without gapps and managed to get it working?

I have been using it since yesterday and the battery life is amazing. But my only issue is that I get frequent slowdowns in applications while scrolling etc. Animations stutter. This mostly happens when I unlock and use or if stop for a moment using the phone heavily. I really don't know what I'm talking about but it seems the CPU governor is too 'conversative' with power saving. Can I change it to a more responsive one?

Edit: I tried with a kernel manager to set all governors to performance but it didn't change anything. Though, after restarting the phone, issue seems to be gone for now. Maybe it slowdowns with uptime? Or something holding good chunk of memory in the background?

Using OrangeFox:

Wipe: Cache, System, Vendor
Format: Data

Install lineage-18.1-20210616-UNOFFICIAL-raphael.zip

Still reboots to recovery after approximately 30 seconds of lineage logo

Edit: Same as @DontBeEvil
Flashing works only with Nikkgaps (core) it seems.
Same here. Had to flash with NikGApps (basic). My phone is encrypted.
So far everything works fine. No problems with Magisk and ANXCamera. Only opening the app drawer and swiping slowly through the homescreens seems a bit choppy. Now it's smooth.

After over a week of use this rom has proven very stable.

However, I am still experiencing very very low earpiece volume. This was not the case on previous roms. Further, it is commented that transmitted voice often becomes robotic.

I've tried various firmware, including the latest global android 11 V12.5.1.0.RFKMIXM.

Mine was a clean flash, with full wipe and format, with nikapps core.

Does anyone else have this problem? And solution? If not, perhaps someone could comment if they did something different so I can try to remove the problem? Thx.

I don't experience these issues. The volume is pretty loud. I think I also have the newest firmware and didn't do something special besides flashing the rom with the NikGApps.

Here are my findings after 2 days of use:
  • Battery life is like EvolutionX (where I come from). Roughly 2 days max. with >6 hours display on time.
  • Rom is very stable. No crashes here.
  • Fingerprint reader works ok. I was surprised of the newest EvolutionX version. I thought it was really quick. Nevertheless it works most of the time and is not something I would complain about.
  • Opening the app drawer and swiping though homescreens sometimes still stutters. It also feels like the maximum speed at which I can swipe the homescreens seems limited. That feels a little bit unresponsive.
    When the app drawer is open it scrolls blazingly fast.
  • The only real complaint I have concerns the Bluetooth. When the screen is locked the connection between my watch and the smartphones drops occasionally and it doesn't connect again until a wake the phone. That's annoying because I use my watch get message notifications.
    It also does not connect automatically after returning from a run where my watch is out of Bluetooth reach. For me it seems like there is a power saving option for Bluetooth enabled but I can't find anything in the settings to turn it off.
    I didn't experience this issue with the stock MIUI, LOS 17 and EvolutionX.
Otherwise I had no problems until now. (y)

    Hi community
    I've never used LineageOS, but was reading about it for years. I always read how clean it is, how smooth it's working and so on. Would be nice to try it, but also would be nice before to know is there any cons in this OS (ROM)?
    Maybe battery life is not that good as in stock?
    Maybe camera not that good as stock 48MP (GCam provide just 12MP sharp images, for 48MP sharp photo need to use stock)?
    Maybe there are some safety issues?
    ect.

    Please, can you share your experience about cons of LineageOS on Mi 9T Pro?
    Thank you
    I've used CyanogenMod and LOS in the past. In my experience it was always more stable than other ROMs, especially regarding updates. I think the developer is doing a great job but you have to keep in mind that this ROM (as all the others) is not official. So you have no OTA updates for example. For the last update it was mandatory to do a wipe which always bugs me a little.
    When it runs the ROM is very stable for me. Sometimes there are animation errors. I don't know what causes them.

    One downside is the camera. LOS has a build in one but it can only use the main camera. The GCam mods worked for my but they do not correct the heavy distortion of the ultra wide angle lens and produce color banding in certain situations like an overcast sky.
    ANXCamera worked good with the Android 10 firmware and older ROM versions but now it always crashes when I try to enable the UWA camera or portrait mode.
    I don't use the 48MP mode.

    Battery life with the new version is in my opinion worse than with the 20210713 one. I only get about 24 hours. I've AOD enabled.
    Also, I experienced that the phone got relatively warm in some situations.

    I can not say much about security. As far as I know LOS is open source which is a good thing. Encryption works for me.


    As a side note:
    I really appreciate the work of the developers here. Nevertheless, I often regret that I didn't buy a phone which is officially supported by LOS or has a stock ROM that I like and that I can root. I miss the OTA Updates without all the issues. I new in advance that I would probably not like MIUI but since the 9t Pro was so popular I always thought that it will definitely get official LOS support.
    This was a expensive reminder for me that hardware specs are maybe not the most important thing of a smartphone.

    Would you be willing to make a MicroG-build?

    MicroG is very valuable for degoogle purposes, but it is increasingly difficult to set up all the relevant parts (GMS/GCM/Nlp/Geo Lookup/Reverse Geo/Fake store/Signature Spoofing/F-Droid privileged extension) properly, so MicroG automates this for official LineageOS builds using this docker image.
    I have tried to create a working Dockerfile for building Raphael already for so many times. Builds are successful but don't boot. Maybe OP can contribute to this so we can also build on our own when OP has no time anymore. Abishek ignores this.

    Hi,

    where can I find "It is recommended to flash latest Android 11 firmware (not vendor) according to your region"? I was only able to find "RAPHAELGlobal-V12.0.2.0.QFKMIXM-10.0-vendor-firmware" but that is a vendor firmware, not an Android 11 firmware. Can somebody please help me find it? (using Mi 9T Pro Global version (raphael)).

    Thanks!
    Here you go.

    Thank you very much for your quick reply! It works! :)

    But doesn't it work this way on stock ROMs? Maybe I'm mistaken, but I didn't use AOD there -- the screen was usually disabled, but it turned on the moment I pressed on the reader.
    I think you're right. With the stock ROM and also with Evolution X it is possible to unlock the phone without AOD or waking the phone.
    But maybe there is a way to activate this feature but I don't think so.

    Need to change data to f2fs!? And out of curiosity, which kernel is used?
    No theres no need to change data. It's Englezos kernel.
    Wow, thanks, a must try. Are u going to keep maintenance? Is call recording and miracast working?

    Edit: miracast works, call recording not
    I don't like these kind of questions to be honest. But for the record I've been releasing my personal builds on my github profile since Jun 7, 2020. I will check what I can do for call recording even though I don't use it.

    Is it Vanilla build ? I would like to install Vanilla build.

    I never is OSS vendor built. If future upgrade from this ROM, can I dirty flash ? I use encryption.

    Thanks
    No gapps included. I don't really recommend dirty flashing but its up to you.

    Yes. This was the problem. The default app is becomes not set in the clean install + Nik gapps core. Thanks.
    Nice to hear that you solved your problem.

    How is this different from the other "unofficial" lineageos 18.1 Rom?
    Feature wise it's the same goold old LineageOS ROM. I don't like bloat I enjoy simplicity and stability. Code wise its completely different since its OSS. Try and let us know.
