Yes It Works But I Found Other Bugs

Vibration not working in Battery Saver Mode

And after using it for a few hours, suddenly the phone turned off and twrp started booting non-stop. Even though I selected and started the system, twrp was always on, the phone would not turn off. I Restored Backup. Chrome Was Open During This Crash But I don't think it's relevant but I don't know why

My Device: Umidigi F1 Play

Used Lineage OShttps://www.mediafire.com/file/5jjq0gjkx13mdqo/lineage-17.1-20210621-UNOFFICIAL-F1_Play.zip/file

Gapps

open_gapps-arm64-10.0-pico-20210619

Sorry Couldn't Recover Logs :(
[Miscellaneous Android Development] Shadow Of Leaf:
vibration not working in battery saver mode is not a bug but battery saver mode disable vibration to juice some battery up

for the system shutdown and twrp loop i will see look on it
[Miscellaneous Android Development] F1Master:
This ROM is above great, it transformed my F1 Play into a proper smartphone.

It has some basic problem in being unable to make/receive calls in SIM1. Solved putting the simcard into SIM2 tray, but still unable to receive calls.

Camera I updated it with the attached one that works like a charm.

Arguably now I have a BETTER camera than with the original ROM.

1M Thanks to the dev for the hard work, and praying he has some spare time to iron out the remaining telephony service bug.

MGC_8.1.101_A9_GV1b_snap.apk

PS: I managed to notice that the problem apparently was due to my new provider's signal at home, as today at work I received calls normally. Hurra!
[Miscellaneous Android Development] Crhada17:
I think I found the source of the TWRP loop or something related to it, I changed the screen style. Sometimes it would change to Stock screen style, but I couldn't understand why at first. It usually happened when there was a notification or something on the screen, and yes, I made sure that the source of the problem was the notification and whatever was on the screen, now I tried it on Shazam.

Sorry for my bad English. If you don't understand, do what I wrote below.

1. Change the display style

2. Install Shazam and set it to have the Shazam icon on the screen

3.then click back and click below buttons or see notifications or something like that

4. It will revert to the stock display style

5. If you do this repeatedly, the system will crash and go into twrp loop.

I hope I explained it well, if there is anything you do not understand, write me and I will explain the mistake again.

(In short, there is a bug in the screen styles, this bug triggers the twrp loop)
[Miscellaneous Android Development] Mannish Boy:
I'd love to put Lineage on an unused Umidigi F1 that I have, but I'm struggling.

ADB works fine while the phone's turned on, I've added all the drivers I've seen suggested, and it shows up as "F1" in device manager. But when I put it into fastboot mode, the computer (Windows 10) can no longer connect to it. Nothing shows up when I type "fastboot devices".

I've tried the SP Flash approach too, but TWRP never seems to be loaded onto the phone. I reset back to the stock firmware, turned on OEM unlocking and USB debugging, then switched the phone off. Used the scatter file from the stock firmware, added the TWRP file for recovery (v 3.5.2), hit download and plugged the phone in.

SP Flash looks like it downloads the recovery just fine. It goes through the motions and gives me the big green tick. But afterwards, no TWRP. I'm holding volume up as it powers on, but it just goes to Android recovery, and no sign of TWRP. The first time I reboot after trying to flash TWRP I get a message saying "Red Status - Your device has failed verification and may not work properly. Please download recovery image with correct signature or disable verified boot."

If anyone has any advice, that'd be awesome! Thanks!

Edit: Oh, and now I'm also seeing "TEE" and "Google" along with some Chinese characters in the top right corner of the screen permanently now, so I obviously got something pretty wrong here! Any way to get rid of that? Would getting Lineage on there remove it?
[Miscellaneous Android Development] Shadow Of Leaf:
you have to install mediatek drivers to use fastboot you can download it from this link https://androiddatahost.com/276a2

for "TEE" and "Google" you have an imei issue i have this problem before and i fix it using this link https://community.umidigi.com/forum.php?mod=viewthread&tid=1375&extra=&page=1
[Miscellaneous Android Development] Shadow Of Leaf:
thanks for test this rom out

if all features in this camera work i will make it the default camera in lineageos

thanks again
[Miscellaneous Android Development] Shadow Of Leaf:
thanks for testing out

i saw this issue before in my phone the screen style just randomly go to default but i never notice it

i will look into it

if did the same problem flash the newest twrp 3.3.1 it will prevent recovery loop just click on reboot the device will reboot
[Miscellaneous Android Development] F1Master:
I noticed some problem with the config for the selfie camera, it takes videos but taking pics it does not work, takes two shots and can't get stored correctly, while portrait mode just killed the app. The back camera otherwise works everything like a charm even in night mode! I didn't noticed all this until now as I'm not a selfie lover anyway...
[Miscellaneous Android Development] Shadow Of Leaf:
ok thanks i will update the google camera go to newest version
[Miscellaneous Android Development] Crhada17:
You're welcome, glad I could help :)
[Miscellaneous Android Development] Shadow Of Leaf:
test this new releases and report back for bugs
[Miscellaneous Android Development] nnSlick:
Hi All,

I was able to flash this ROM from stock using TWRP. It boots up OK and it is very snappy. The problem I ran into is that it does not recognize my Tracfone SIM which is recognized by other phones. Any idea why does that happen?

Also, it looks like after flashing this ROM the phone does not have a system partition. When I tried to use TWRP to flash an .img file (not a .zip file) only two partitions available for flashing: boot and recovery, but no system. Is this normal?

TIA.
[Miscellaneous Android Development] Shadow Of Leaf:
thanks for testing out

you can try to change you SIM Place from Sim1 to sim2 or vice-versa

about the flashing img you can flash img using fastboot just go to about and click on build number five time then go to system options and then developer options you will found advanced reboot and long click on power button click reboot and bootloader

and flash your imgs on fastboot
[Miscellaneous Android Development] nnSlick:
Thanks @Shadow Of Leaf !

I did try both SIM slots and neither was recognized. I power off the phone then change the SIM slot.

I did flash the twrp img file using the following command:

fastboot flash recovery twrp.img

so I should use

fastboot flash system <image name>.img

to flash an .img file to the system partition?

Thanks.
[Miscellaneous Android Development] nnSlick:
UPDATE: I have two Tracfone SIMs. I try to use the second one and this time it was detected. So one possibility is that radio is working on one network provider but not on another (Tracfone uses many providers). The working SIM shows 'Verizon' as the network, FYI.
[Miscellaneous Android Development] kayuz:
I am trying to install this too, but when in fastboot my device can't be seen.

It is stucked at waiting for devices on the PC, and the phone is set in fastboot mode at the bottom.

Nothing to do, I tried remove drivers and reinstall them, also ticked OEM unlock and ADB connection activated.

I wanted to try something new for my F1 :)
[Miscellaneous Android Development] Shadow Of Leaf:
did your pc detect the phone , go to device Manager and see if fastboot driver is installed
[Miscellaneous Android Development] Shadow Of Leaf:
new update that could fix random shutdown bug

try it out
[Miscellaneous Android Development] Crhada17:
Hello, you know that there is an effect place called miravision in umidigi stock system, can you adapt it on lineage os?

Or is there an application similar to Miravision where we can adjust settings such as contrast?
[Miscellaneous Android Development] Shadow Of Leaf:
i see what can i do
[Miscellaneous Android Development] Crhada17:
FM Radio Distorts Sound

No Sound After Turning On FM Radio No Sound Even When FM Radio Is Turned Off (I tested with Spotify and YouTube)

sound comes back after restarting the device

Lineage OS:

lineage-17.1-20210810-UNOFFICIAL-F1_EEA

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

www.mediafire.com

Gapps Version: open_gapps-arm64-10.0-pico-20210812
[Miscellaneous Android Development] Shadow Of Leaf:
weird

you said that after you turned your fm radio off there are no sound

ok let me see what i can do
[Miscellaneous Android Development] Shadow Of Leaf:
for now the sudden shutdown fixed

it was caused by prebuilted NFC stacks , switching to AOSP NFC stacks fix it

for the sound i think that when you plug your headphone and restart the headphone will be the primary audio source not headphones

if you plug out and restart sound will work again

i will dig into this issue
[Miscellaneous Android Development] kayuz:
Regarding security patches? :)
[Miscellaneous Android Development] Shadow Of Leaf:
i want to fix bugs first make it enforcing then update security patches

but i see what i can do
[Miscellaneous Android Development] kayuz:
I finally flashed your rom and tried for today.

Issues that I encountered are:

There's a 4/5sec delay when you turn off a call and it effectively don't display anything about active call

Screen recording feature is broken, only black screen (talking about native recorded of course)

Ringtone are played at very high level of audio even put on lowest setting possible, I waked up all the pharmacy with my Ringtone :-D

Also, when on call, if I put the speaker on the volume is abnormally high, again I made people trigger at me for that issue :-D

And then that's all, all round is a good rom with good battery life and nice things like Android 10, I am looking forward for new releases of course.

Thank you for your work B-)
[Miscellaneous Android Development] Shadow Of Leaf:
for the abnormal volume you can disable besloudness (there is an app to do it)

for the delay i have that too i will see what i can do
[Miscellaneous Android Development] kayuz:
Thank you.

Can you check out if USB is correctly working?

I can't use MTP connecting the phone to pc :(
[Miscellaneous Android Development] Shadow Of Leaf:
yes its working

plug in and click on usb notification and choose mtp it will work

just let your phone be unlocked
[Miscellaneous Android Development] Crhada17:
I think the sudden shutdown problem still persists, when we enter a twitter page in chrome, if we play two videos together, the device restarts itself. (This error may be caused by me, I made a few changes in the system. You will have to test)

and Miravision is necessary for me. Is there an application where I can adjust settings such as the contrast setting? I searched but couldn't find it, if not, unfortunately I will have to go back to stock rom, I don't want it at all :(

Lineage Os:lineage-17.1-20210819-UNOFFICIAL-F1_EEA
[Miscellaneous Android Development] Shadow Of Leaf:
use firefox for now chrome cause soft reboot (not sudden shutdown) due to video codec

miravision need a lot of work to implement it and i dont have source code for that

you can use this application https://play.google.com/store/apps/details?id=co.uk.quickdoc.screenbalance&hl=en

also you can return to stockrom anytime
[Miscellaneous Android Development] Crhada17:
thank you so much :)
[Miscellaneous Android Development] Kangburra:
Thank you for this. I have had a good installation experience. I had to disable MAC randomising as this was blocking my router on reconnect. I also had to manually copy the adbkey for adb debugging. Otherwise it all seems good.
[Miscellaneous Android Development] Crhada17:
Audio fx not working sometimes

I haven't been able to figure out the reason yet, sometimes the sound returns to its original state when listening to music on spotify.

(It fixes when you take off the earphones and put them on)
[Miscellaneous Android Development] Crhada17:
gifs not working on gboard

When I try to throw a gif from the Gboard gif section of WhatsApp, it says the file format is not supported, or it gives this error on the gifs I downloaded from the internet.

Hi, I have an Umidigi F1 and was thinking of flashing this Lineage OS 17.1 image but reading the comments it seems as there are a few bugs - it says VoLTE doesn't work - what is the result of that? I use my phone for 4G USB tethering a lot and need that to work.
[Miscellaneous Android Development] Shadow Of Leaf:
volte is not working but tethering is working
[Miscellaneous Android Development] aindriu80:
Do you still get 4g data speeds? I thought telcos were phasing out non Volte infrastructure, it might make the phone 1/2 useless?
[Miscellaneous Android Development] Shadow Of Leaf:
n

volte means voice over lte an enhacement of calling voice using internet LTE

it does not have any relation data connection and you will get 4g data speeds
[Miscellaneous Android Development] aindriu80:
I'm having a different problem, I have tried 3 different versions of TWRP and although I get an install success message it doesn't boot up into TWRP afterwards - it goes to the phone.

3 versions of TWRP I tried:-

https://xdaforums.com/t/recovery-unofficial-twrp-3-5-2-for-umidigi-f1-and-f1-play.4287017/

TWRP-3.3.1-F1

TWRP-3.3.1-F1

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

www.mediafire.com

What could be the problem?

I also tried from Windows (as opposed to Linux) but it was worse, I only got errors in fastboot mode, I tried installing the MediaTek drivers but didn't work.
[Miscellaneous Android Development] Shadow Of Leaf:
go to fastboot and try this command sudo fastboot flash recovery recovery.img

and fastboot reboot when rebooting click on volume up and power for long as the boot splash disappear

then you will see twrp logo
[Miscellaneous Android Development] aindriu80:
Didn't work :S

Commands used:

1. adb devices

2. adb reboot bootloader

3. fastboot devices

3. sudo fastboot flash recovery TWRP-3.5.2-F1.img

4. sudo fastboot boot twrp.img

Also used -> sudo fastboot reboot

I tried rebooting a few times... When I try Power up & Power it just (10 seconds later) reboots the phone.

I get the Orange mode warning on the left but then it goes into Android.

If I press power down on boot it goes into recovery mode. It's like there is some error with TWRP but everything else is working.
[Miscellaneous Android Development] Kangburra:
Reflash the correct stock ROM, I had this problem and it was solved by a reflash and the install TWRP again
[Miscellaneous Android Development] aindriu80:
This is not going well, The phone Umidigi F1 seems to be hard bricked now and it won't start up, I flashed the ROM at the beginning of this tutorial and the phone is wont start :

Flash your phone with the latest stock rom version (20190903 download link )
[Miscellaneous Android Development] Kangburra:
I don't have the play version, but I did this on the F1 and then it all worked perfectly. I can't help more as there are differences between the F1 and the Play version
[Miscellaneous Android Development] aindriu80:
That's ok....I have the F1 version, the above seems to be for the Play so a bit of a mistake but the instructions should be a bit clearer. I'm downloading the F1 now and going to try and flash it. hopefully, I can recover from it.
[Miscellaneous Android Development] Kangburra:
This is the one I used, for the EU 2019090418_g38v71c2k_kw_f1_eea.rar

You can do Download only, if possible or Firmware Upgrade if not, DO NOT do format all.
[Miscellaneous Android Development] aindriu80:
I got it back from the dead, It was the wrong ROM I was using. I went to the Umidigi Forums and got the following ROM for Umidigi F1 (european edition) :

https://community.umidigi.com/forum.php?mod=viewthread&tid=18875&extra=page%3D1

There were a few steps that made a difference -

In Smart Phone Flash Tool (SP 5.1916) it wouldn't work initially - I had to go into Format then select

Auto Format Flash + Format whole flash except bootloader

After completing a format I had to unplug the phone and then plug it back in again and then back to Download and flash the F1 ROM.

The only problem now is that the ROM I have has TEE and Google in red on the top right-hand side of the screen. I'm going to try to install TWRP and then the Lineage ROM.

**Edit

I got TWRP installed, I used TWRP-3.3.1-F1.img and the following commands:

adb devices

adb reboot bootloader

fastboot devices

fastboot recovery TWRP-3.3.1-F1.img

fastboot reboot recovery

Then hold down the Volume UP until UMIDIGI logo appeared. I think I didn't hold the volume up long enough.

Once I got into TWRP I could install lineage-17.1-20210821-UNOFFICIAL-F1.zip I rebooted the phoned and it went into Lineage, I then went back into TWRP and tried to install GAPPS Stock Android 10 but it was too big so I used the micro version open_gapps-arm64-10.0-micro-20210915.zip ,

I have some bugs though, like the fingerprint reader is nowhere to be seen and I got an error with the Android Setup Wizard, it wouldn't start - then it suggested I had an iPhone (which I don't) and now it won't complete.

​

** I've spent a day using LineageOS 17.1 and it's a very nice improvement over Android 9, I can understand that Google Pay doesn't work because it's an Unofficial ROM but how come the fingerprint reader doesn't work? I don't see any mentions on this thread about it.

** I notice pop up advertisements that I didn't have before, I can't tell if it's an app I installed or Lineage. Also, the FM radio doesn't work even with headphone plugged in.
[Miscellaneous Android Development] Jimidoli:
after i installed the same stock rom in the link i have the same problems with the tee and google watermark.

to fix the imei with sn writer gave me no solution. also rooted apps like "freezer" was no a solution.

i tried many houers to delete the watermark but i had no succes.

this is a very bad problem with the tee google watermark.

only on a *unofficiel custom rom the watermarks disappers but on a *factory stock custom rom the watermarks appears back.
[Miscellaneous Android Development] aindriu80:
I went from that 'Tee Google' watermark to the Lineage ROM and didn't try to remove the watermarks but I think the watermarks are there to make you upgrade the stock ROM. I don't have the link in front of me but there is a video on the Umidigi forums showing how to upgrade over the air (OTA?), you have to disable the existing OTA and install another version, that might get rid of the 'Tee Google' watermark.
[Miscellaneous Android Development] Jimidoli:
i have bought a *anycast streamer but on the unofficiel rom mirra and the bluetooth doesent work. on the unofficiel rom. 4g do not work too. so iam gone back to the factory stock rom but there was the *watermarks and the watermarks disturb me so much that iam gone back to the unofficiel rom. X)

EDIT: @Shadow Of Leaf : i tryed 1000 time your newest build but it didnt work.

i used twrp 3.5.2 f1 play (buggy ?)

other builds had bad problems too "it was not possible" to install most of the (diffrent) custom roms.

i tryed the twrp 3.3.1 f1 play and tadaaa! it works! and i could install your newest build 821 zip. :) 4g works! :)

i was 2 days really frustrated but now iam happy.

*i tell that, because other people have maybe the same problems.

and somthing else:

THANK YOU 1000 TIMES!!! for your hard work and efford :)

Edit:

i had a succes to stream out but it works not so well or iam to stupid to handle that.

i streamed 1 video with sound from my handy to my anycast stream dongle and so to my tv.

i used a rooted app called "allcast"
[Miscellaneous Android Development] yudati:
Hi

first of all thank you very much for your perfect job

Really enjoy it, I have also the problem with incoming calls and I can't solve it with your solution to copy the libmtk-ril.so file, any idea how can I solve it ?

Or maybe the new version will come soon ?

And btw I installed the Rom from old link

The new link isn't updated

I'm getting error with the new F1 play link that is not compatible with F1 play

I tried the 2 links and non of them works
[Miscellaneous Android Development] Jimidoli:
ihad problems to install the newest rom too. i solved it and used an other twrp. instead twrp 3.5.2 (f1 play) i used the version twrp 3.3.1 f1 play. with the older twrp 3.3.1 i was able to install the newest rom. with twrp 3.5.2 i had errors to install the rom too. so try twrp 3.3.1 f1 play for the newest rom.
[Miscellaneous Android Development] yudati:
Working great 👍

Love you man

Thank you so much 💗🥰
[Miscellaneous Android Development] Crhada17:

Hi

i have some wired problem

I can shoot photos only but not video

No matter what camera app I'm using o just can't take any videos

On open camera it doesn't open the video to record

On the original app it's showing like it's recording but when I'm opening the gallery I see that the video file is damage and can't be play... Any help please?

I have the latest version

Using f1 play
[Miscellaneous Android Development] Kangburra:
I don't have the play version but I would check the file type and resolution. Also make sure you are recording to internal memory and not an SD card.
[Miscellaneous Android Development] yudati:
Yes.... it's recording internal storage...sure

Hi. I downloaded and tried to install this ROM (what is in the first forum entry by the author) on my UMIDIGI F1 Play : https://www.mediafire.com/file/5e87kyoyho6eo8n/lineage-17.1-20210821-UNOFFICIAL-F1_EEA.zip/file - but there was just an error code:

" E3004: This package is for device: F1; this device is: F1_Play ".

So from twrp (3.5.2_10-0) therefore i can not install it. Can you help me?
[Miscellaneous Android Development] yudati:
That's what happened to me as well ....you need to install it with different version of twrp

3.3.1 and than it'll work
[Miscellaneous Android Development] Shadow Of Leaf:
use TWRP 3.3.1 it will work

TWRP 3.3.1 download link : https://xdaforums.com/t/recovery-decryption-works-unofficial-twrp-3-3-1-for-umidigi-f1-play.4007315/
[Miscellaneous Android Development] pwdhun:
Many thanks guys,

With linked TWRP 3.3.1 umidigi-play-f1 version it is work!

(with official twrp 3.3.1 for um f1 play - from twrp.me the error code is remains the same!)

A new question about the LA Trust service:

- How i can enable SELinux (what is red and off now in the Trust menu) ?

- Also the google sercurity pack level notification is old and red now (but I understand that since the rom is not the latest either) ..

- And the encryption is red and off too.

Thanks in advance for the solutions!
[Miscellaneous Android Development] yudati:
Can someone please check if the recording video works ? ( Try to watch the video after recording it)

I tried reinstall everything from beginning and still not working
[Miscellaneous Android Development] Kangburra:
No issues here with the F1 and stock camera app. I viewed the video with the stock gallery app too.
[Miscellaneous Android Development] yudati:
My problem is on the F1 Play....
