I've had my Mijia 4k for around a year, and am looking to take it apart and clean/remove dust, BUT I also don't really want to poke the bear and mess something up. Anyone have any advice?
[Android Software Development] bebech:
Hi guys,

Since a few days I've got this Mi update trying to install when I shutdown my Fengmi, It goes for a few seconds then I've got a black screen with "Error!" displayed, I have to wait a minute then the projector restart.

On the first page of this forum it says :

"Disable the "smart update" in the projector settings so that it doesn't try to download and install OTAs (which would just display an "error" message after each boot, when it fails to install it)'

And

"Using any of the above features (even [ROOT] ones) should be safe and shouldn't prevent you from installing stock OTA updates afterwards (no system file is modified)"

I'm a bit lost ^^

Edit : Ok my bad

"Firmware updates won't install if files on your system or kernel partition are modified. Using the ProjecTivy Tools and installing the Google apps won't modify existing system files, but rooting with magisk will modify the kernel. So before any update, you have to restore your kernel (aka "boot") partition using TWRP, and then reapply Magisk once update is done."

Thanks .

Hello guys,

I've installed the tool on my anglee device, and now I'm trying to find the "HDCP key reset" in the engineering menu.

Some people mentioned in this forum, this is the only English menu, but I can't see it.

Can you please guide me.

Fengmi 4K Cinema

I have Fengmi 4K cinema laser L176FCN when I try to flash from a flash drive to the Chinese version after root, I got a brick. The button blinks and that’s it. This is the second such projector in my memory. What to do?
[Android Software Development] pean74:
As you can see in the picture i get strange lines wandering upwards across the screen when using 4k@60. This can be fixed using 4k@50 or lower or changing color depth to 422 or 420. What may be the cause of this? Not good enough hdmi? Been getting the same result from two different android boxes. Chromecast ultra works perfectly though (but I believe the CCU uses 420) And I have A mijia

Good afternoon,

Past the few days i've been getting an pop up insisting on updating the software, if I proceed on pressing to continue then I get an error and I can't even turn off the projector unless I plug it out of the electricity. This is starting to annoy me so much, I've got the Xiaomi Fengmi L176FCN, I have rooted it and turned off all the chinese apps 6 months ago followed by the manual on the website.

Update 1.3.105 (Stabile)

Thanks

You cant update if you have rooted the device, remove root and then flash the update and then add root back if required.

Wemax a300 batman - mitv update

Hello

on my memax a300 it seems to be a new update available of mitv from 'about' menu

Did somebody tried it ?

It says version 1.3.105 which is still the same but might be because im using a rooted device ?
[Android Software Development] xyzbingo:
Did you find any solution? I have the same problem with the same hardware :/
[Android Software Development] matt77w:
Hi, I am having the same problem and understand the above statement, I'm just not sure on the steps needed to restore the boot partition and then reapply Magisk. Can anyone help? Is there a video or step by step guide anywhere so that I don't mess?

I'm running the Batman model (I know this is correct). I don't seem to be able to find the backup I (think I!) created before I first installed Magisk and rooted. Is there another option to allow me to install the OTA update. Everything I try still gives me the error on reboot. Basically I think I need a 'clean' boot partition I can restore to allow me to install the OTA update and then return to my current boot partition. Is this an option or am I going to have to start from scratch again with the whole install?
[Android Software Development] matt77w:
If I don't have a backed up boot partition (made prior to magisk) to restore in order to install OTA, what would you suggest?
[Android Software Development] KciNicK:
install the full rom, its in the first post...
[Android Software Development] matt77w:
Will I lose all my apps and end up with the Chinese menus etc again?
[Android Software Development] KciNicK:

[Android Software Development] matt77w:
[Expletive!!!!!] I don't understand, I've done an OTA update previously with no issues tho! Think I need to check the partition backups I have on the projector. part of the problem is that they don't have sensible names or the correct date! Think I'll investigate these before starting from scratch. Thank you for the info tho

Batman - mitv update - custom props broken

Hi spocky

I have updated the build version of my batman wemax a300 to 20.6.4.793

(Previously from stock was 9.4.30.494)

By restoring stock firmware + made the OTA update from about menu + install projectivy tools , then unrooted device with magisk 20.4 , uninstall stock apps etc following your sequence of steps.

But when trying install of custom props , it says 'could'nt set custom build props ' and prompts me 'is your device rooted' and it is actually , magisk is installed with usb key and twrp app, then rebooted before trying this install of custom props. Also the check root access says your device is rooted. I think the OTA update build has made some changes not compatible with your custom props.

Then consequently (i would say) the google apps install create pb with home page launcher with black screen.

Can we dig into this ?

Fyi: This new build says it fixes bugs also hdmi 2.0 (i have crackle sounds through hdmi using firetv stick and now it seems to have disapppeared)
[Android Software Development] YANGHY:
I think, on page 1, spocky said Magisk 20.x is not compatible with his tool, especially, the custom prop.

You should use Magisk 19.x to get this custom prop working.
[Android Software Development] regis.larrode:
Yep that was it ! now google apps are working again when rerooting using magisk 19.4 . Thanks !

notification blob?

hi guys... i have a bit of an issue having updated the MIUI via OTA.

There;s this blob on the bottom right hand side that I just can't figure out how to remove. It stays there all the time no matter what screen I'm on so I suspect it's from the MIUI.

Any solution? Thanks.

Hi

Does anyone know a bit what has changed in new build firmware 20.x from OTA for batman (im using wemax a300) ?

Im not sure what im saying but in engineering menu there is an entry 'dolby' and was thinking this is new ?? The release notes (or kind of..) says they fixed hdmi 2.0 bugs (google translate + click photo camera to translate what is on screen )
[Android Software Development] doelski:
i thought of the same and did that. but no can't click it.
[Android Software Development] regis.larrode:
If you install google apps it will change . I guess its one of the mitv app , did you uninstall all stock apps ?

Hi again!

I've finally received the 3d glasses. And yesterday I was trying several 3d films.

I've tried by wifi (sharing files) and by hdmi. The glasses works well... but I see stuttering problems and often the image stops for 1-2 seconds each 1-3 min. It's really anoying. If I use HDMI, At the pc screen I can see the image smothly. I have a i7 with a gtx 1080.

I've thougth to use a pendrive, but if it must be formatted in fat32.... I can't copy a file of 10-15gb in a FAT32 formatted pendrive/hard disk.

How can I fix this problem?
[Android Software Development] doelski:
yes all stock apps uninstalled. this is weird. I need to root again perhaps, but the same USB drive and port that previously worked fine now no longer working. can't get to TWRP

I just root my projector but it display very often "Unfortunately, Leanback Launcher has stopped" and at start it seem block on the start image :x

Should I factory reset or restore backup?

Thanks
[Android Software Development] Gnomepises:
I'm gonna answer myself this time.

I thought it was neccesary to use FAT32 for all pendrives with this kind of projectors BUT It is possible to use a pendrive with NTFS format. I've tried with a 3D film using a pendrive and everything played smoothly. A 3D film of 16gb of size.

The result is very nice and I'm very happy

After install google apps and do all thinks related with the root sucessfully I get the blank screen, the ATV launcher do not works and when I press home button I get only the "device settings" app but no "MiProjecTivyTools". REAL problem is that when I press "device settings" button it opens but dissapear inmediately and I cannot enable USB debugging in this way to go to the recovery to install Magics v19.4 (problem seems to be Magiks 20.3 installed...)

Any idea about how to reboot on recovery without using adb or how to fix this device settings shutdown?

I first made sure that I have a batman and that it is running with this firmware version. But while flashing the screen went dark and the projector powered itself off. After trying to power it on again it just flashed 3 times with the power button and there is no spinning up of the laser. The screen stays black and it powers off again :(

Hi,

I've been silent recently because I needed to focus on the next release of the tools. I need to fix a few bugs, but hopefully it shouldn't be long before the release (well, that is, if I manage work on it instead of playingf TLOU2 :))

I've uploaded the last OTA for batman (494 to 793).

Sorry this happened. I'll add a warning on the 2nd post.

I suppose it came with a more recent firmware, and 494 has not support for it.

Could you try to flash the latest OTA (if it doesn't power off and accept to flash files) ? The new kernel should support it.

And if any other owner of this device can upload the /Dev/block/backup, I'll extract the ROM and share the full firmware here.

You need to enable ADB connection and accept the connexion on your projector.

Thank you for the reply. Really appreciate it. I tried to update the latest OTA . It seems to flash it. At least the button light stays on for a couple of minutes and then it shuts itself off.

But unfortunately the OTA 793 did not change anything. Still no picture, the power button only flashes three times and it turns itself off. Hopefully somebody is able to share the new backup.

Problems with Fengmi 4K [batman]

First of all, thanks to all of you for the good content of this thread. Unfortunately, I'm yet to install the TV tools since I've encoutered problems with my Fengmi 4k (the white version).

Though it's not the purpose of the topic, I hope you can help me.

For the last few days my Fengmi Cinema 4k fails to boot (during apparently an update ?) (see video on Youtube : V2KKALSsUhI ) it's noteworthy that I can stay in recovery mode with no pb, pointing to a ROM pb (or update pb).

I tried to boot on the recovery rom, as well as update to "Full rom 1.3.105 (6.0.1.494)" & "OTA [user] from 6.0.1.494 to 6.0.1.793(still 1.3.105)" but I always have the same problem.

Bangood doesn't do a particulary good job in helping me, so hopefully you will have an idea.

I haven't found a list of the diferent ROM for my device, is there such a list somewhere so that I can blindly try to find a working ROM for my device ?
[Android Software Development] spocky12:
Hi,

If you can boot to recovery mode, there's an entry that allows you to fully reset your device (the same as flashing a full firmware from this thread, but using the one embedded in your device).

So, i kinda fixed my Xiaomi UST 4k ( thx [MENTION=2683857]dj666jp[/MENTION]). I own the projector now for almost one year. After some month i started having the same problems as everybody (long bootime) etc.

First jetzt leaving the case open on the left side did the trick. But it got worse overtime. I grounded down the ribbing on the inside of the upper case (see picture attached) - no effect.

Then i realized that even without the upper case the bootuptime was very long. Starting from [MENTION=2683857]dj666jp[/MENTION] thread i did some try and error. The problem was the black ribbon cable (as always). I removed both stripes of the tape and the metal shielding. The trick to get my UST booting up again fast was to put something under the black ribbon cable to push it upwards (see the red rectangle in the second picture). Then i had to stick a very thick layer auf double sided coated tissue paper near the red rectangle to keep the metal shield from pushing it down again. With the metal shield attached (screes not really firm) it boots up fast again.

So why only "kinda" fixed? Because i still have to keep the case open. If i close the case it seems to put to much pressure on the ribbon cable again. :eek:. Keeping the case to wide open seems to put the upper case in the picture - i see shadows of the case in the left and right lower corner.

So, maybe somebody finds this help full. The new Xiaomi Mijia 1S 4K seems to have the same case as the old one. I hope they fix the annoying problem with the ribbon cable in the new version of the UST.

Temperature/fan sensing issue

Hi all, thanks for all the incredible work from everyone who's contributed helpfully on this thread. My projector, the original Chinese model, has developed an issue I couldn't find described on this page and I wondered whether anyone could help.

Over a week ago it displayed a warning that the projector's fan system was impeded, and it would shut down to prevent damage. However, since then I have been unable to get it to work again. It boots normally, but seconds afterwards the same message displays and it shuts down. I've cold-booted, done a full system restore (the issue doesn't seem to kick in while it's in recovery mode), and even left it for a week unplugged, but it keeps happening every time and has made the device unusable.

An earlier post quoted what might be the relevant part of the user manual:

"Temperature warning and error warnings will be displayed automatically whenever the temperature exceeds its maximum range to inform you that the machine will be automatically turning off. Temperature switch: The laser comes equipped with a physical high temperature sensor which will automatically shut down its power source when its maximum acceptable temperature is exceeded."

I've also read separately that there's also a device that monitors whether the fans are running at the proper speed (presumably what the temperature sensor is telling it they should be running at), which seems to tie in with the error message mentioning a problem with the fans, but to my ear they sound no different to the way they always did on startup. So it seems to me that the malfunction is likely to be in one of three things: the fans, the fan monitor or the temperature sensor. Given that a system restore didn't help I guess it's not a software issue.

Truth is that unless it's fairly simple I'm probably not going to be able to fix it for myself and will need to send it for private repair, but since it isn't a common model in this country I know it would only help to be able to point a repair company in the right direction. I'd be most grateful for any help.
