Dirty flash still not supported (tree changed), please make a clean flash

Thank you so much for keepng Lineage alive, its very much appreciated.

@leo_97 thank you for this new build! Installed it straight away and now the phone is running since then and also, I've flashed with battery at 67% and atm, after a quite hard usage to test out the new features, I'm on 13%. Basically, so far so good!
p2a42, twrp 3.7, rooted, unencrypted

Thank you @leo_97 !
I was frustrated that Lineageos 18.1 was no longer maintained when I saw this update!
It's amazing
To all users and developers who tested and created this ROM, is it time to switch on this version ?
Or is it better to wait ?
For example, automatic update is possible after install ?

You are welcome
If it's time to switch, I believe it's a matter of personal decision. Maybe you could wait the next build and then decide...
If with "automatic updates" you mean OTA updates, then the answer (as already pointed out by @utwer ) is no. But once the trees are stable enough, I hope every user will be able to just update to the newer versions flashing ROM ZIP through TWRP (just like it's done on LOS18.1)
BTW, IDK if you already saw it, but we are maintaining a monthly build of LOS18.1 which you can download from here. The source tree used there is far more tested (as it's older) than this one. Anyway, except by the encryption thing, you shouldn't have any problems using this LOS19.1 ROM as our amazing developers made an excellent job here.

Reg, Ive installed it and I may say it is quite good. Not tried to root it yet. Dont have direct problems with ROM and functionality, for me everything works. Camera, Location, GSM, Data, WiFi. With developer options I've turned off Animation scale on three options to OFF, and is good. Stable reliable.
MindTheGapps-12.1 works every app from Google, Phone, Contact, Gmail, maps...etc...
What I need root mostly is for Call recording (Skvalex) and Viper4Android.
Some words about twrp-3.7.0_9-0-kuntao.img,
With this I have only problems, so far I lost a few backups and I need to install it all over again a few times allready. Disappointed very. I can't rally on this when I make a nandroid ba.ckups.
Also lost backups for LOS18.1 and I am been very pis....ed off. Error 255 on System recovery, other Data, Boot, EFS, Vendor, etc.. recovery is good.
So I've installed OrageFox for Kuntao. Tried several backups to restore already and I may say I am very satisfied. Puh
What is on my mind, when I installed a Magisk 25.2, no matter of LOS 18.1 or 19.1 with very few modules, after 7-8 reboots I've got boot loops which is beyond repairable.. Try to remove modules in TWRP in file manager, uninstall whole magisk, no way, but what it is seems that DATA got corrupted some how, everytime.
There were also installed TWRP mentioned above.
Now I am with OrangeFox and I will try tomorrow to Root it and see is there any connection between Magisk and recovery software (OrangeFox or TWRP).
Reg

Tried quickly this ROM yesterday. In general all working, but didn't test much.
Few feedbacks:
-Scaler for brightness level is weird, very different from the original Lenovo roms. Anyway, not really important, but something that I noticed.
-Missing haptic feedback when using the fingerprint reader as a gesture button. Again, not critical, but I am really accustomed to it and thus I noticed immediately.
-Missing haptic feedback intensity regulation, or could not find it. It's there for general call/notification vibration, but if I remember correctly lineage could also change haptic.
Impressed that you could integrate also some lenovo features, even if of course not all of them
If you want me to test something more specific, please let me know. Ah, my model is the 4 GB/ 64 GB combination.
Cheers!

So for 18.1 we can just flash the newer versions via TWRP and do not have to reinstall the entire ROM?

So,
Resolved issue of bootloops:
after you install SU like Magisk, and wan to freeze apps by Titanium Backup or Neo-Backup, Apps which causes bootloops are ROM's Phone and Massages (In my case, for 16.1, 18.1, 19.1), I freeze Audio.apk who need to be shutdown for Viper4Android app who takes audio management and freezing is OK.
But Phone and Massages which are frozen cause bootloops, so you need to return from freeze state somehow in TWRP or OrangeFox with file management or revert backup. Revert backup is easier .
Camera; found issue when suddenly is out of work and cannot be connected to app. Also have problems with video cast Skype, Viber, Whatsapp, Telegram video is frozen. Hardly switch in Camera app from Camera mode to Video mode and vice-versa.
Clock & Info; missing dock icons and info, can't "capture" moment for reason when they disappear but after a while all is returned again.
P2oggle, left switch button work okey in form of 0.4 version.
Reg,
thanks on the development for this 19.1 ROM.

Hello,
I've been using this ROM as my daily driver and couldn't confirm this camera bug, could you please give a few extra details? I tested on Telegram app. Which version are you using? The Play Store's one or the one from Telegram's official website? Did you give the app "While using app" permission or "Ask every time" permission for camera? Are you sure the QS Tile "Camera access" is activated (available) when the mentioned bug occurs?
Regarding the Clock widget, yes, there's a small glitch and I'm not sure on how to fix it, if it doesn't load at all, a system reboot should fix it.
P2oggle v1.2 is 100% working as far as I can tell, so you guys can try it too if you want.

I'm not sure if it's possible to "fix" the brightness slider.
If with "haptic feedback" you mean the phone vibration, you can just adjust it to your liking in Settings > Lenovo parts > Vibration strength, it should affect fp reader too, dunno if it affects call vibration but IFAIK it should.

Yes on latest Telegram app from web site, tried with Google Meet, Whatsapp, Viber.., always breaking connection with API/drivers. Yes I gave all permissions to Camera. If I am not giving permissions for camera, I have always noticed to confirm what I am giving, so I am excluded from this solution. And clean storage and cashe from app regular but not prevail.
But, in a while after installed a new ROM without giving SU/Root I noticed this behavior, right after I wrote earlier post up. My bad .
Choppy startup of camera, can't easily transfer from video 2 camera and vice-versa, so I tell to my self to test intensively.
Regarding the Clock widget, yes, there's a small glitch and I'm not sure on how to fix it, if it doesn't load at all, a system reboot should fix it.

Big Thank you for this release. Will try it. - test

Great job, dude.
Previous versions had some buggy charging driver that left a wakelock running after each charging, and u had to restart phone each time or leave it to slowly drain battery by not going to sleep.
Somehow this problems seems to be gone in your build and that is awesome.
I've been using the build for about 2 weeks now and so far everything seems to be working fine.

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. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
This thread is for Official LineageOS 14.1 builds for chagallwifi (SM-T800) The following will not be supported here:
Custom kernels
Mods
Xposed
I don't support Xposed and any logcat which includes a Xposed module will be ignored. You're kindly invited to not report bugs if you:
Flashed a custom kernel
Installed or did mods from untrusted sources
Modified system files
Have not attempted a clean flash
First time flashing LineageOS 14.1 on your device, or coming from another ROM?
Download the zip(s)
Install a compatible Recovery
Perform a nandroid backup of your current ROM (Optional)
Wipe data/factory reset
Flash LineageOS
Install the Google Apps addon package (Optional)
Reboot
Make sure you have the Marshmallow bootloader. Guide is in the comments below.
There will be a new build every week, every Monday.
The builds will no longer be personally tested by me before being uploaded (but everything will probably be fine)
Change logs will no longer be posted within every new build, but instead when the changes are uploaded to GitHub. I will try though to post changes for major bugs or fixes as they are released.
Some builds might feature only minor changes, ie. only updating the LineageOS source

For OTA updates to flash correctly:
Update your TWRP to 3.1.0-1 (USE THE 2017-05-04 BUILD OR LATER. DO NOT USE A BUILD FROM BEFORE THIS DATE)
You can get Official TWRP 3.1.0-1 for chagallwifi from this link!
TWRP for CHAGALLWIFI
This updated TWRP recovery image contains a fix that will allow it to flash OTA updates properly!

How to update to Marshmallow bootloader (required for 20170324 and later builds)
Updating the bootloader is very quick and doesn't wipe data or repartition the device.
If the last Samsung ROM you had was 6.0.1 Touchwiz, you already have Marshmallow bootloader and don't need to follow these steps. (If you were on MM, and it still won't boot, follow the steps below)
1. Download the bootloader-only Odin package: T800XXU1CPK2.tar.md5
This has the latest Marshmallow bootloader (December 2016)
https://www.androidfilehost.com/?fid=457095661767146298
2. Download Odin 3.11
You can skip this if you already have a working Odin
https://www.androidfilehost.com/?fid=673368273298937183
3. Shutdown your tablet and start it up by holding Power+Home+Volume Down to enter Download Mode. Volume Down is the one right next to the power button. Really shut it down and use this key combination, if you use Advanced Restart, or go into download mode via TWRP the bootloader won't change.
4. Make sure the screen of your tablet has a green android symbol with a "Downloading..." text
5. Open Odin3_v3.11.1.exe and follow the instructions in this image:
If anything is missing, you WON'T flash bootloader successfully.
6. Click Start. Your tablet will automatically reboot back into your ROM.
7. To verify you have the new bootloader, you can run in terminal emulator "getprop ro.bootloader". It should say T800XXU1CPK2.
Thanks @ZakooZ for the post!

Thx for your work
Looking forward to testing it out

Thank you very much for your work!

It doesn't works for me, I only see boot animation and it doesn't start even after 20 minutes. I tried Paulicat version and works fine. Whi? I did a clean flash.

Same for me. Bootllop after flashing ROM and latest Gapps (nano).

Yeah, bootlooping.

I installed with a full wipe (including internal sdcard), using latest pico gapps.
No issues...
I also recently updated my bootloader to Mashmallow, but I doubt that's what makes mine bootup while some bootloop.

Bootlooping? How far does it boot ?
Please be 100% certain that you wiped dalvik, system, data and cache in twrp and try flashing without gapps. Did you change anything such as flash custom kernels etc?
Could one of you take a logcat during boot for me please. It has to be user error seeing as mine is working fine, and others are working fine. The number of downloads - complaints shows that.
Just plug your tablet into you PC while it's booting (make sure you have adb installed)
Then , once you start to see the screentype adb logcat into your terminal (./adb logcat if windows or Linux)
Thanks

Just upgrade from @Paulicat's Jan 17th build to this Jan 25th build; just flashed lineage, open gapps nano and SuperSU (in that order, in one go) and rebooted.
Looks like the video problems of the previous release are not present here; I can now play YouTube Videos at high res and use the HW codecs of MX Player without stuttering; previously I had to drop from 1080p to 720p or use the MX+ codecs to make it play smooth.
The WebView component apparently still have problems; using for instance FlipBoard to read articles causes a crash/weird screen flickering from time to time, associated with a crash. The log reports a WebView crash (there's first a "OpenGLRenderer: GL error: Out of memory!" followed by a google-breakpad dump of "WebView:55.0.2883.105" "A arm 04 armv7l samsung/lineage_chagallwifi/chagallwifi:7.1.1/NMF26V/e609fadfba:userdebug/test-keys" "webview" "OpenGL ES 3.0|ARM|Mali-T628" and a long hex dump.
Finally, GPS does not work out of the box; the gpsd still misses a few libraries. I've copied them from elsewhere (RR, if I recall correctly) and have placed libsec-ril.so and libxml.so in /system/lib -- and then GPS works instantly (as far as I can tell it may lock on faster than on the previous build).
I guess the WebView has to be fixed upstream, but maybe the missing gps related libraries could be included in the next build?
Thanks for your great work!

Just upgrade from @Paulicat's Jan 17th build to this Jan 25th build; just flashed lineage, open gapps nano and SuperSU (in that order, in one go) and rebooted.
Looks like the video problems of the previous release are not present here; I can now play YouTube Videos at high res and use the HW codecs of MX Player without stuttering; previously I had to drop from 1080p to 720p or use the MX+ codecs to make it play smooth.
The WebView component apparently still have problems; using for instance FlipBoard to read articles causes a crash/weird screen flickering from time to time, associated with a crash. The log reports a WebView crash (there's first a "OpenGLRenderer: GL error: Out of memory!" followed by a google-breakpad dump of "WebView:55.0.2883.105" "A arm 04 armv7l samsung/lineage_chagallwifi/chagallwifi:7.1.1/NMF26V/e609fadfba:userdebug/test-keys" "webview" "OpenGL ES 3.0|ARM|Mali-T628" and a long hex dump.

Glad most things is working for you!
Yep, this build has a more updated device tree then what Paulicat had so there are a few fixes!
GPSD is being investigated by @deadman96385 and should be an easy enough implementation
Thats the first time I have heard about the webview implementation, would you mind sending a full log? Thanks for letting us know!

So far, it's better -- also appears more "smooth" and fluid in use, I think

Yep, possibly just a few missing libraries or a different linking method, or something. Good you're working with @deadman96385 on this also; he already responded to this in the other thread when I debugged and reported it related to the previous build.

Wiped all for 3 times, it doesn't boot.

I have a f2fs data partition. Perhaps that ist the reason for the bootloop?! (i have the bootloop too)

Clean flash - boot OK - flashed pico OK - flashed superSU OK - boot OK
No prob at all :good:

My T800 is currently happily running the now out of date [AOSP 7.0][T700/T705/T800/T805] by @Schischu so I'm looking to upgrade. Here are apps I'd like to know work before I give this ROM a try. If anyone can tell me if they work or not I'd appreciate it. If any of them are considered mods I apologize in advance as I've read the OP mods policy. In any case I'd never ask for their support or inclusion in the ROM as that's my responsibility.
Here's my list:
Viper4Android
Substratum
LastPass (some other 7.1.1 ROMs have issues with this app)
Netflix
Plex

Whaddup, XDA? ^_^
This began as a modest little post, aptly named Post#3333 in the Resurrection Remix thread to help keeping the thread clean. Many thanks to @varund7726 for his support and making it the official RR Bacon FAQ!
It gained more attention than I thought it would so I decided to make a more general version in a dedicated thread.
This is not my work but a collection of answers by amazing people that roam these digital lands. Of course, I do appreciate you clicking that Thank you button . I hope people looking for answers will find their way here. If someone has any input, feel free to drop it in the thread or send me a PM and I'll update the post if needed. It may be best to not ask new questions here, you'll find more satisfying answers in the appropriate threads of the custom ROM you're using or in the general Help thread.
Now, let's get this out of the way first:
Code:
What are you reading this for? There isn't a single Bacon owner with valid warranty anymore. Anyway, here's the original disclaimer:
You have the [U]right[/U] to unlock your device, not the [U]obligation[/U] to do so.
Anything you flash can and will be used against you in a court of technical dispute.
If you get your device bricked, you will [B]not[/B] be provided with a new one.
If your mother in law disappears as a result of something mentioned in this thread,
I will happily take your donations to thank me but I will not be held responsible!
Mind that this is – and probably will continue to be – a work in progress.
This is an attempt to collect general solutions, which will not always work in every case.
Please DO NOT QUOTE THIS ENTIRE POST! Thanks.

1. GENERAL
1.a. How can this FAQ help me? Why did you make this?
My goal is to maintain a one-size-fits-all thread where people can find answers to the most common current problems for the OnePlus One a.k.a. Bacon. It also serves as a detailed guide through the flashing process. The reason I'm doing this is threefold: 1) Despite the fact that this is a 2014 device, the 1+1 community is still booming. Best proof of that is that our very own Bacon is by far the most popular device for LineageOS with currently over 80,000 installs! I'd love to honor that fact. 2) This is my first support thread, I hope to learn a great deal from it. 3) I honestly enjoy helping people =)
1.b. Why isn’t anyone helping me?
Keep in mind that XDA is not your personal tech support. The idea is that we help each other as a community, not to expect an immediate answer to your problem. If you do not add any useful technical information to your query, your post may not be considered, this is even more so the case in development threads.
There are three ways (that can be combined) to achieve a technically sound post:
Attach a logcat! See 1.c. on how to do this.
Provide screenshots, especially handy with aesthetic issues.
Provide the exact steps to reproduce the problem (be VERY specific).
Tip: use the time that you’re waiting for an answer to find it yourself. If you managed to resolve it yourself, follow-up on your own post and explain how you did it, it may be helpful to other users in the future.
1.c. Creating a logcat
This'll only take a minute and may provide invaluable information for any developer or someone trying to help. There are a number of ways to create them, this tutorial explains a remote technique. I do believe this is the easiest way:
Download CatLog from the Play Store
Make sure you have a dedicated 'menu' button (CatLog is old skool)
Run the app, give it root rights, [optional] pause the current flow with the pause button and then clear the window tapping the circle with the X in the middle top right (this will provide peace of mind, the constant stream can be a bit overwhelming)
Tap the menu button, press Record followed by OK. Any activity is now being recorded
Press your home key and launch the app that's giving you trouble, let the crash happen and repeat it a few times
Drag down notifications and tap the cat, it'll state "select to stop recording"
CatLog will now show you what it has recorded, use the search feature to check if no privacy sensitive information (your e-mail, a phone number etc.) has been collected, you can edit this out manually with a text editor if needed
You can simply tap the menu key again and select Send to share the log, this feature will also add device info (brand, model, Android version ...)
If you'd like to share it manually or want to make some edits first, you'll find the file in [internal storage]/catlog/saved_logs
2. PREPARING
2.a. EXT4 vs. F2FS
A lot can be said about filesystems but I won't go into any technical debates on here. The main difference boils down to this:
F2FS is arguably faster than EXT4; EXT4 is arguably more stable than F2FS.
In real use performance, not much difference will be noticed in terms of speed. Since the release of Oreo for Bacon, however, stability on F2FS has decreased drastically or it is unsupported entirely. If you have never changed this yourself, the system will most likely be formatted to EXT4. You can check with DiskInfo or in recovery. In case you want to run Nougat on F2FS or you want to return to EXT4 but forgot how, here's a refresher:
In recovery, go to Wipe > Advanced Wipe
Select a single partition
Tap “Repair or Change File System” (if you see “Invalid partition selection” appearing, it means the partition’s file system cannot be changed
On top you can see the current file system, tap “Change File System” followed by the one you want (stick to either EXT4 or F2FS)
Swipe to confirm
I found this XDA article (interview with Francisco Franco) quite interesting on this topic.
2.b. What else do I need? (Prerequisites)
A good working TWRP
The ROM zip of your choosing
Gapps (ARM/8.1/nano, there are plenty alternatives, check with your ROM maker which one is advised)
last CM13 snapshot (only if you didn't have CM13 before)
You should place all downloaded files in the root of your internal storage (/sdcard). It's stongly recommended to check md5 hashes! In case of Gapps, download the md5 checksum file and place it together with the zip.
2.c. C6 or C7, which is the best firmware? (troubleshooting network issues)
None. There are mixed results on both, depending on which network(s) you use. Which one works best for you? The only way to find out is by flashing one of the three versions below (that differs from your current version, check under About phone > Baseband version. The recommended one for most users is C6-00241 (the most likely one you currently have).
Here are three very common firmwares and a Frankenstein release:
Download DI.3.0.c6-00241
Download 4.0.1.c7-00013 (2016)
Download 4.0.1.c7-00011 (2016)
@MrSHME's Frankenstein Release
[instructions and credits]
There's a whole load of them available in this thread. I've done some elaborated testing there, read my findings here.
Important note when flashing firmware: backup your modem and EFS partitions first! It may happen that the system hangs in boot animation after a firmware flash (I experienced this a few times). Give it some time and it should automatically boot back to recovery. In recovery, reboot back to system (don't do any wiping or anything) and it should boot just fine. If the system keeps hanging for over 20 minutes, manually force a shutdown (long press power) and try booting regularly again. Still no luck? Boot to recovery and flash other firmware or restore your modem backup.
2.d. What kernel should I use?
You don't have to use any. Want to take the plunge anyway? Sure, check out post #3 for a list. You can make a backup of your kernel/blobs with Flashify
Read (much much) more about tweaking in this excellent guide by @Saber
3. FLASHING
Always make a nandroid backup before you flash anything!
3.a. Installing TWRP
Before flashing anything, make sure you are using a compatible TWRP! You'll find a download link to the one I'm using in this FAQ, I'll keep it updated. I know this is basic information but to avoid any mistakes, I'm providing all needed steps:
Download a TWRP .img file
Move it to the adb (official download) folder where adb and fastboot exe's are located
[this is no requirement but let's do this for the clarity of these steps] rename it to recovery.img
Reboot device into fastboot via advanced reboot menu, 'adb reboot bootloader' command or – if the device is off – press and hold "Power + Volume UP" until "Fastboot Mode" appears
Setup the correct drivers and connect the device to the PC/Mac
Open a command line (terminal on Mac I guess) in the adb folder
type "fastboot devices" to see if the system picks up the device
type "fastboot flash recovery recovery.img" to flash TWRP
Disconnect the device from the PC
Press and hold power until the device turns off
Hold "Power + Volume DOWN" to boot into the newly flashed TWRP recovery
3.b. How to flash
Always make a nandroid backup before you flash anything!
Clean Flash:
In TWRP, wipe by swiping factory settings. If you're experiencing issues, it's best to do a full wipe (Advanced > select System + Data + Cache + Dalvik-ART Cache)
[optional] Flash last CM13 snapshot and do another full wipe. This step is crucial when you've never been on CM13 before. This flash will fix/prevent a wide variety of issues! You only need to do this once.
Flash the ROM zip
[optional] Flash a custom kernel
Flash Gapps (ARM/nano, version should be the same as ROM), check Gapps compatibility in ROM thread.
[optional] If root is desired, flash Magisk (stable or beta)
[optional] Flash other mods
Wipe Cache/Dalvik-ART Cache and reboot
Dirty Flash (update):
Reboot to TWRP
Flash the ROM zip
Wipe Cache/Dalvik-ART Cache and reboot
Semi-Dirty Flash:
This is basically the clean flash procedure but you backup the /data partition before wiping and restore it afterwards (or don't wipe /data at all). I do not recommend this method.
Example (my flashing procedure for a specific Oreo ROM):
Download ROM and Open Gapps to root. Check ROM md5 hash with MiXplorer
Backup all user apps + a few system elements (messages, call logs etc.) with TitaniumBackup (+pro key)
Copy the TitaniumBackup folder to my PC
Reboot to latest TWRP, create Nandroid backup of System and Data (sometimes copy that one to PC as well)
Wipe /system + /data + /cache + /art-dalvik cache
Flash ROM + Gapps + OP5 camera mod + iYTBP + Magisk beta (all in one go), wipe caches after flashing and reboot
I let Google setup install all apps, then restore app data with TiBu, this feels more clean
Restore system elements with TiBu + apply AdAway lists + restore Android ID (for my banking app) and reboot
Enjoy awesomeness!
This seems like a lot of work but it doesn't take more than an hour. Since releases are currently pretty far apart, it's only a small effort for many days of smooth sailing. If release frequency would increase, I wouldn't make a Nandroid and wouldn't copy everything to PC every single time. If I don't have Wi-Fi for some reason, I restore all apps + data with TiBu instead of using Google setup.
3.c. I'm seeing two red errors in TWRP while flashing
They are LOS related and have no effect on the flash procedure, don't worry about it, you can safely ignore them.
3.d. I'm getting an error while flashing Gapps
Error 70: You're trying to flash a package that is too large such as Stock. Try a smaller package.
Error 64: Wrong architecture, you need an ARM package, not ARM64/x86/x86_64.
Error 20: Wrong version, you need 6.x for Marshmallow, 7.x for Nougat
3.d. I dirty flashed and something doesn't work anymore
Please do not inquire about issues after (semi-)dirty flashing. The first step for you to take is to perform a clean flash. If the issue is still present and it hasn't been posted before (PLEASE use search!), then post your inquiry in the ROM thread.
4. CRITICAL
4.a. My screen is going black, I can only see notifications
This behavior is caused when a profile has lock screen disabled. The only way to recover from this condition is to clean flash, or restore a backup that was made prior to setting up the profile. It may be possible to reboot successfully if one is in a location or situation that triggers a profile that doesn't have lock screen disabled, then change the problem profile settings (unconfirmed).
4.b. My device just exploded!
It's most likely unrelated to a software problem but please, feel free to share pictures!
4.c. The other person (nearly) can't hear me during a call
Can't be heard
In /system/build.prop, change
ro.qc.sdk.audio.fluencetype=fluence
to
ro.qc.sdk.audio.fluencetype=none
Edit /system/etc/audio_platform_info.xml (in Oreo this file moved to /system/vendor/etc)
<device name="SND_DEVICE_IN_HANDSET_MIC" acdb_id="40" />
to
<device name="SND_DEVICE_IN_HANDSET_MIC" acdb_id="4" />
Audio comes out low
remove
ro.qc.sdk.audio.fluencetype=fluence
change
persist.audio.fluence.voicecall=true
persist.audio.fluence.voicerec=false
persist.audio.fluence.speaker=false
(flashable version)
Reboot.
Still having problems? Test your sensors and mic more thoroughly with an app like this, there may be a hardware failure. Before opening her up, you can do a last software check by trying another ROM or by returning to 100% stock.
4.d. I have another audio/microphone problem
Please refer to the OnePlus One Audio Mods Collection, a genious collection of all sorts of fixes and workarounds to achieve fully featured audio on the OPO.
4.e. Can't read or write to internal storage (/sdcard)
Your /sdcard partition is most likely corrupt! Now what? When this happens to /system or /data we can simply perform a clean flash. Wiping our internal storage, however, means wiping a lot of precious data that is not included in a Nandroid backup so it's crucial to make regular backups manually. A lot of trouble can be avoided with cloud syncing (Dropbox, Google Photos, etc.). When read/write errors present themselves (camera can't save photos, not enough space errors while there's plenty, folders disappear, etc.) it's important to work fast before all your data becomes unavailable indefinitely. Here's how you can reset your internal storage in a non-destructive manner:
Copy the entire content of your internal storage (/sdcard) to an external location (PC or OTG drive). Make sure the real important things are immortalized (e.g. your cat photos/videos are synced with Google Photos and/or are trending on YouTube)!
Reboot to TWRP
You may want to create a nandroid backup at this point but do not forget to copy the backup to your PC or make the backup via OTG as we're about to wipe the internal storage (and with it, all internal backups)
Go to Wipe > Advanced and select only Internal storage, confirm to wipe (you may experience some discomfort at this point, this is normal)
Reboot to TWRP (from recovery to recovery, that's right)
Now copy all content back from the folder on your computer to the internal storage. You should be able to do this simply over USB while TWRP is active. If you don't, go to the main TWRP menu, tap 'Mount' followed by 'Enable MTP'
When the copy is complete, reboot to System and your trouble should be gone!
We're doing the wipe AND the restore inside recovery because if you would boot your device with an empty /sdcard partition, the Android system and all running apps would start freaking out and get going on all sorts of crazy, recreating their folders and files.
Tip: this is the perfect opportunity to sieve through those files! I recommend not just copying everything back but only the things you still need. Exclude folders of apps that aren't installed anymore and skip unused media files. This will decrease the chance of future corruption. Take some time to make your internal storage shipshape!
5. QUICK FIXES
5.a. The camera app can't connect to the camera
If you flashed something like OxygenOS Blobs, your camera will not work unless you set SELinux to Permissive. You should find this in your ROM settings (e.g. for RR this is under Settings > Configurations > Miscellaneous > Selinux mode > Permissive) or you can easily do this with SELinuxModeChanger.
Why this is a bad idea: SELinux or Security Enhanced Linux prevents malicious apps from gaining unlimited system level access by exploiting security holes. By setting it to Permissive, you’re disabling this extra layer of security. Infections due to this are rare but do happen, you’ve been informed.
5.b. Google Assistant isn't working or "OK Google" detection fails (this may be obsolete by now, please notify me if it is)
See 4.c., “Audio comes out low”.
5.c. QS toggle 'drops' when trying to add it
This may happen when attempting to add one of the lower QS toggles. There are two ways to work around this bug:
By lowering the display size: go to Settings > Accessibility > Display size (or under custom ROM configurations) and change it to Smaller or Smallest
By messing around: move icons from the top to the QS panel until you're able to slide the QS toggle you need without 'dropping' it
This video shows it works fine:
6. OTHER
6.a. How do I apply themes and which ones can I use?
OMS compatible ROMs only! To start, install Substratum from the Play Store, open it and grant it root rights (both substratum and masquerade). Then search the Play Store for substratum themes that are compatible with your Android version. Some will cost you something but most are really worth it and there are some great free ones as well. After installing a theme, apply it in Substratum. Don't forget to read the theme creator's instructions, some combinations can cause trouble!
6.b. Fast/Quick Charge isn't working
That's because the OnePlus One doesn't support it. You can, however, tweak charging rates with kernel tweaks (which is still limited, don't expect dash charge speeds). Equip yourself with proper hardware. A ‘smart’ charging station and quality cables can go a long way. Mind that faster charging is not better charging per se. You may shorten the lifespan of your battery when pushing it to the limits. Charging with the official charger/cable (which should take about 2 hours from 0 to 100%) is still the best way to treat your battery. Also note that if you got your device back in 2014, there's a good chance your battery doesn't have its full capacity anymore, longer charge rates and shorter lifespans can be expected. That being said, the OPO was equipped with a kickass quality battery, even after abusing it for all these years, many users have reported it still works great!
7. MODS
7.a. ViPER4Android
Since Magisk is more widely adopted, installing V4A has become very easy.
In Magisk Manager, tap the three lines top left
Tap Downloads
Scroll down to ViPER4Android FX and tap the download icon
Tap Install followed by Reboot
Once booted, go into Magisk > Downloads again
ViPER will now be on top, tap it
You'll find a link to the latest APK, download and install it
That's it. Open it and change all the settings you want, then reboot once more to make sure it all runs fine.
7.b. Camera mods
The OnePlus 5 camera software has been ported (download here) to Bacon and it works great, this is my current favourite.
Great camera mod: CameraNextModV2. It's just a simple flash away.
Not much of a mod but a Camera app optimized for our OPO: Bacon Camera!.
And good to know: Google Camera 4.1.006.135988111 is the last compatible version for Bacon.

[Changelog]
2018-08-23
Howdy! I've been away (or at least very inactive) for a few weeks due to family vacation and other stuff – including two quite tragic events. That's life I guess
Anyway, interesting development seems to be never ending for this amazing device. The immortality of Bacon has yet again been confirmed with the release of PIE! This was predicted by my teenage antiheroes "Weebl and Bob" back in 2002; they are true visionaries :')
That's not one (KitKat), not two (Lollipop), not three (Marshmallow), not four (Nougat), not five (Oreo) but SIX (PIE!) major Android iterations that have seen light on this chunck of awesomeness. At this rate we might even see Android Queijadinha on the OPO! But let's not get ahead of ourselves. Let's celebrate and enjoy Pie's release first. Time to take a P (Captain Underpants, anyone?). Tra-la-laaa!
Created "PIE!!!!!" section
Added POSP to both Oreo and Pie sections
Added PixysOS
Updated Oreo titles.
2018-05-25
Added Cosmic-OS
Updated all ROM Index Oreo titles
The legendary AOSP by the equally legendary @Agent_fabulous is being discontinued more to come, though?...

I am planning on a clean flash soon and often refer to your guide as the best source. After all it is titled "The Ultimate OnePlus Guide", so it must be true.
May I request that you begin updating posts #1-#4 to include Oreo? I find the tips you posted here (link) helpful.

This is fantastic!
But no matter what I do I can't install even core gapps. I flash them via adb sideload, perform a factory reset and nothing.. I feel like I've tried everything. There's no problem with Magisk tho. Can you please include some gapps in the rom?

Amazing news! Official ROM and latest Android version!
Hopefully the permissive SELinux can be sorted out with enough logs, but still, very nice work so far.

Does anyone can help me about the recovery via fastboot installation? I mean is there need to change slot e.t.c... And after recoverie's flashing, how we reboot to recovery, via a simple fastboot command?Thanks.

Yeah, a12 not so fast at gapps bringup, we have limited chose to BitGapps, Nikgapps or FlameGapps, and Nikgapps with FlameGapps have some issues while flashing it on some devices (already reported to the dev), and only BitGapps works fine, but there are only Minimal package.
However i created a modified Nikgapps(stock) package - download

Generally speaking, IMHO doesn't matter how you got into recovery be it by command or power+vol+

Click to collapse
When you flash something over fastboot you are to manage slots. When you do by recovery it manages slots. So up to flashing the recovery you'll manage slots. Afterwards flashes are done by recovery. Since recovery changes slots when you flash rom or update. Both slots should have the same firmware level (e.g. android 11 firmware.) If you have incompatible firmware on other slot it may cause problems on next update or full flash. IMHO op should explain a bit more about slot management. The same process is known to cause unwanted problems before. You can check the lineageos 18.1 oss thread for it.

Hi,
Is it possible to safely install this ROM from android 10 stock EU version? (or, must I already be under A11 and in this case what should I do?)
I'm still stuck on A10 and the September 2020 security patch on my French version of the Mi A3
Sorry I'm a beginner

I think you must first update to a11. Do factory reset on your a10 first.

Problem is that I still do not have the possibility to do OTA to A11...
In France we are literally blocked on A10 and the September 2020 security patch...

Then you can flash it with mi flash.

I don't understand what to do in order not to lose my data, I would just like to update.
If I want to install the update without fear I have to make a backup. OK
To make a full backup I need TWRP. OK
To install TWRP to be able to make my backup and not lose any data I have to root my device with magisk. OK
If I root my device with magisk it makes me wipe all my data...

If I were you I wouldn't rely on twrp for backup. Because once you update to A11 you ll have problem with twrp hence restoring it. On the other hand even if you are able to restore it somehow, probably you would end up with a bootloop anyway. Because when android version changes, data partition backup of other versions won't be compatible with newer one. I suggest you to have per app backup within os.

New update is out!

New update is out!

everything working fine, new icons and animations for udfps are pretty good and now it recognizes really fast. one thing i noticed is that the screen flicks when unlocking with figngerprint but just a little bit, its not something that really bothers as before. updating was fine without even needing to make a backup. anyways ty for, basically, the best rom for mi a3, if it wasnt that, i think we all would have already changed it. keep up the good work!

I just did the installation and the rom is fantastic!
Leaving Miui..
Everything seems to work very well.
Congratulations to those involved!!

*/
Device Specific Issues:
• None
Requirements
• You must be on Latest firmware v11.0.3.0 or v11.0.2.0
• You must use any of the recommended recovery (links are given below).

Notes
• Build type: User
• Encryption not supported, Decrypted by default
• Selinux is Enforcing
• FMRadio Included
• Do not flash recovery.img available on the spark download website
Flashing Instructions:
Clean flash (Coming from a different ROM):
• Download ROM
• Download Custom Google Apps Package (Like Nikgapps core/basic or Mindthegapps) if the ROM is Vanilla variant (On GApps ROM variant Google Apps are included, don't flash a separate Custom Google Apps package)
• Reboot to Recovery.
• Wipe System, Data, Vendor, Cache, Dalvik/ART cache partitions
• Flash latest stable firmware v11.0.3.0 before flashing ROM
• Flash ROM zip
• Flash Custom Google Apps Package if the ROM is Vanilla variant
• Reboot to system
To get root access, Reboot to recovery after ROM setup and flash Magisk.zip
BOOTLOOP SITUATION: If you are coming from stock/custom MIUI or any ROM which had data ENCRYPTION, you will face bootloop and can not boot into the system. In such case you need to FORMAT data after flashing the ROM. Otherwise the ROM won't boot (Read detailed instructions from here)
Dirty flash (Updating to a newer build):
• Download the new update ROM zip
• Reboot to recovery
• Do not wipe anything
• Flash the new update ROM zip
• Flash the same Custom Google Apps Package again you flashed before (For vanilla users)
• Flash Magisk again if you are rooted before (For rooted users)
• Wipe Cache and Dalvik/ART cache
• Reboot to system
Important note regarding SparkOS 13.6 update
This is a huge rebase of the ROM's source code after the March update, So Clean flash is MANDATORY for all users. Some bugs from previous versions have been fixed in this version and some new features can be noticed. Some customizations have been temporarily removed (eg: Smart charging, QS row & column customisation etc) and will be added in future releases (Read official community post).
You should be aware of some known source bugs in this release before updating to 13.6. These bugs are not device specific and are present in all Spark official devices which will be fixed in the next update.
Known bugs are;
1. Launcher settings are crashing with light theme (works fine with dark theme). You can use a different Launcher but I think Pixel launcher Extended will not work anymore as spark is now completely based on lineage
2. Shortcut buttons glitches in recent panel.
3. Visual glitch on Quicksettings/Statusbar after a reboot (Restarting SystemUI fixes it for now)

No issues with viper4Android here.
Check if you've rooted properly?
Or maybe you are using a mod version of viper4Android.

Been using it for half a year and it's the best Android 13 rom I tried (not that there's many that are up to date)

I used the repackaged v4a from github. Clearly something went wrong here if it's working at your end. I'll try again later when I'm home as I'll need to install from scratch having reverted to A12. Guessing maybe I just needed to reboot again or something. Here's the version I used:
GitHub - programminghoch10/ViPER4AndroidRepackaged: A refined ViPER4Android installer.
A refined ViPER4Android installer. Contribute to programminghoch10/ViPER4AndroidRepackaged development by creating an account on GitHub.
github.com
I have to say the smooth responsiveness on these new A12/A13 ROM builds is surprising given how often A11 would lock up for me. Maybe my device just finally needed a reset idk.

OK. Mystery solved. Turns out that Viper4Android does indeed work - it just needed an extra reboot.
So I flash it > reboot > v4a App appears on next boot but doesn't work > reboot again > v4a works.
Weird but makes sense. Sorry for the confusion.

I couldn't receive this kind of google login authorization on this rom "is it you trying to sign in". Device wasn't appearing in google account double verification. No problem in a13 elixir.
Also sadly no option 2g connectivity.
Rom itself seems smooth. ATM moved back to A10

I have problem, the screen show on/ off at redmi boot logo

CPU cores seam to be locked to 1400 mhz

Hello İ installed latest Spark OS gapps build on my a205f i loved the rom but it has a bug phone screen freezes cant close the screen no reaction to calls,notifications,holding down the power button the only solution is to wait for the battery drain it happened 2 times what can i do i guees this build is laggy

This is possibly a long shot but any chance of modified files for higher quality audio on Bluetooth SBC (or AAC)? It used to be you could patch it in via Magisk but the module no longer works on newer android versions and if I'm correct the edits need to be made before a ROM is built. If you're able to, any chance of some experimental files for me to try out?
I think the values are in a2dp_sbc_encoder for SBC, a2dp_aac for AAC. A2DP_XXX_DEFAULT_BITRATE 000 where XXX is SBC or AAC and 000 is the bitrate in kbit/s.

Hi,
I installed this rom, until I see it I'm liking it, but the screen rotation doesn't work.
Any idea?
Thanks...

Hello everyone, just flashed this ROM on my Vince (coming from Elixir 3.3 - A13).
Since I use this phone to debug my apps, I need to connect Chrome DevTools to it.
What I've done so far:
- wiped everything
- installed Spark-13.3-Official-vince-20230105-gapps
- installed Magisk 25.2
- registered my Google account
- updated all apps (through Play Store)
- enabled Developer options, then USB debugging
Now, when I launch Chrome DevTools on PC, I can see the phone but the webpages list is empty; it also doesn't show any WebView instance (see the screenshot below).
Remote debug was working with Elixir 3.3 on the same phone and PC, so I suppose the difference is in some ROM setting... something to be changed here, but I'm out of ideas...
Does anyone have any suggestions about this?

First, make sure you have enabled auto rotate screen option. It is disabled by default.
If it's enabled send a screenshot from sensor test app (available in playstore). ROM doesn't have issues auto rotates screen.

Great work! Will test it when I have time, been waiting for this..

Hi all. I read these P2 forums for long time, but never participated. I love our P2 phone, riding a P2 since the release date and never changed. Now I got a message from my bank that the android version is too outdated to use their banking app, and they want me to switch to a newer OS. I could have ditched the P2, but couldn't. Therefore....easiest solution was to buy a second one xD I will test on the backup unit some of the roms available here, probably starting from the roms of @leo_97 . I need a stable daily driver, thus when I find something that works for me I will freeze it there for some time. But, in the meantime, I can help out with testing, starting from mid April onwards thus, feel free to contact me, and I will be a bit more active (and not passive) here in XDA for the coming months.
Cheers to all, and thanks @leo_97 , @Astridxx, @XiaoAk (and @mikeioannina for all the past efforts on P2!).

Hi
I just tested it on a P2 for a few hours and it works great! Thanks!
Is there any way to get full device encryption to work?
If I understand correctly, someone can access the phone's files even if you have a pin or password as it is now.

You are welcome
So, IFAIK we don't have a way to make FDE work on A13 ROMs, A13 moved to FBE (File Based Encryption) which is not supported by 3.18.x kernel and we don't have rn a patch available that could enable it on our kernel version.
Regarding data access, I believe so. Without storage encryption, booting into recovery will already give access to the files. IIRC to this date encryption is fully working only on A11-based ROMs and maybe on some A12 ones.

Okay, so I'm stuck in a boot loop. I flashed the ROM from the link above but the phone won't start up. I just get the Lineage booting screen with the circle moving right to left. I've left it for 15 minutes just in case the first boot was slow but nothing else happens. I've tried to restore my original backup which was Lineage 17.1. It seemed to work, no errors from TWRP but now i just get the Lenovo screen and then it boots to fastboot mode. I flashed Lineage 20 for a second time but the same happened. I tried a different backup from August last year, again it just boots to fastboot.
Any ideas?
Cheers, Si.
EDIT: I've just noticed that I missed out step 3, reboot to recovery between Data wipe and flash ROM.
Now it boots no problem.
Cheers, Simon.
EDIT AGAIN: I still can't revert to either of my previous backups of Lineage 17.1. I would really like to be able to do this. Can anyone suggest why it will only boot to fastboot mode after a seemingly successful restore?
Thank you,
Simon.

@simes303
Don't know what the problem is, but I'd flash stock via fastboot. Then reinstall TWRP and restore LOS.
When things go wrong it's better to start from scratch rather than tinkering around and doing temporary fixes.

how is the battry life anyone?

Hi,
How is this different from flashing stock with TWRP?
Cheers, Si.

Used briefly but battery life seems worse, its like draining. Using 12L Lineage os and its way better.

Didn't test much but its way waay noticable, you wouldn't want to use when you see the difference (didn't differ with or without gapps)
btw thx to all devs, using lineage os a12.1 and its good on battery

Battery life for me is considerably better than the Lineage 17.1 that I was using before, no question. I'd estimate almost twice the duration. I'm very happy with this ROM, thanks to all involved in developing it.
Simon.

I've actually just bought a brand new 64 Gb Lenovo P2 pretty cheap from eBay and I will definitely be flashing this Rom onto it.
Thanks again,
Simon.

Hi,
Does this ROM have USB OTG support? I can't get the phone to connect to either my external SSD drive or my bicycle helmet camera since I flashed this ROM. Both these things connected via OTG cable to my phone when I was running Lineage 17.1 and they also connect to the new P2 that I bought recently that still has stock OS. I've tried three OTG checker apps which all state that my phone is OTG compatible.
Thanks, Simon.

Hello Simon,
Yes, it does have OTG support. IFAIK it should work correctly with both FAT32 and NTFS partition types on external storage devices.
