[A14] Low Screen Brightness after Userspace Reboot

[bluetree2009]

I have also removed the jailbreak environment and tried re-jailbreaking.

I heard from some netizens that the brightness was adjusted to the lowest level, making it unable to automatically adjust to a visible level.

I'm on the same version and device as you.

It isn't the brightness that causes it, I was able to unlock my phone via FaceID, open cc, long press and adjust brightness and volume and turn off the device (I know it all worked because of haptic feedback).

The Fugu beta releases had a userspace reboot button instead of doing it automatically so what I did was always just respring via TrollStore afterwards.

Since Dopamine release it has been 30/70 success rate, most of the time the screen goes black, I have to turn off and do it all again.

I can also confirm it isn't a tweak issue (eve and opa said this a couple of times) as I have tested with a clean environment and got the same black screen.

This must be stock bug. But anyhow I will look into this in more detail with a tester soon.

An update regarding this issue, ever since Dopamine 1.0.4 and ElleKit 0.6.2, userspace reboots works as they should. Same device, version and tweaks.

This bug still exists when i restart phone and try to Break ios15.4.1 iphone12 Dopamine 1.0.5

[Vitamoon]

Same for me, 15.4.1 iPhone 12 (13,2) on Dopamine 1.0.5; this screen problem has occurred on every build of Dopamine I have used (all of them from 1.0.0).

iOS 15.4.1 on iPhone 12 and I have the same issue with the latest dopamine v1.1

have to keep restarting device and retrying, takes about 4 times to get it to work

[bluetree2009]

retrying

yes ，the same issue~

[Vorshim92]

me too! I'm on iphone 12 ios 15.4. 9/10 i got blackscreen after jailbreak with touchscreen working (just press where there is the torch and see if it's working). I already try to remove jailbreak enviroment many times but everytime I install ellekit after a new installation I got this problem. With Dopamine 1 and 1.1 I don't know if the problem is dopamine or ellekit or maybe some shit I have in the phone that "remove jailbreak" can't remove... any suggestions/fix? However, I am quite certain it is Ellekit because before installing it through Sileo, after removing the environment, so in a completely CLEAN situation, I have a success rate of 10/10 with Dopamine.

Same version and device,Dopamine v1.1.2.This bug still exists. So, when will this bug be fix? I can't use my phone at all after the jailbreak is completed.

[ajhawley]

I’ve not had this happen to me for a few weeks now, it’s obviously caused by something else and not dopamine, currently on v1.1.2 and not had this issue

the fix is to just respring manually after the userspace reboot

[Vorshim92]

Yes! Just make a shortcut for siri and when you are in the black lockscreen just press the power button for siri and send the command for the respring

[bluetree2009]

how let siri do the respring?

update:On my phone, killall SpringBoard doesn't work, the screen remains black after running the command. But I found another way, if you have a Mac, you can connect the USB cable to the Mac, use QuickTime Player to set the display to your iPhone, then press the power button to make the screen light up (I can only tell by feel iPhone screen is lit), when the phone is connected to QuickTime Player, the screen will return to its original state. NOTE: Maybe this only works on my phone. The translation is from google, so sorry for confusing you

Hi guys! I found on discord a 100% solution working!

I've tried everything too, attempting to send the simple respring command via terminal through SSH on PC or with Siri as shown in the picture 'killall Springboard,' but nothing. However, it's evident that the respring executed by this app works on a different level, and I assure you it ALWAYS works. 100%. Create a shortcut for Siri that launches the app I've attached below (which you obviously need to install through Trollstore), and you're done. When you find yourself on the lock screen with a completely black screen, press the power button for a few seconds to activate Siri and give the command for your shortcut (mine, for example, is 'Launch Instarespring')

I wrote a simple daemon that should slightly alleviate this issue by respring the phone once after reboot userspace. No action is needed after rebooting the user space, and it should finish automatically. Install "respring after reboot userspace" from https://invalidunit.github.io/repo/

[jalsco]

On Dopamine 1.1.11 . Yes I get the "screen darkness" problem also (iOS 15.4.1 on 12 Pro Max) . A simple "restart Springboard" seems to fix it. Can barely make out the text, but knowing it is 2nd menu item from top on the Dopamine screen is enough to be able to do a Respring.

[OnesuchDev]

A potential way to work around this within Dopamine without finding the root cause would be for code injected into launchd to check whether SpringBoard is being launched for the first time, and if so, to inject a tiny tweak into it causing it to exit(0) when it has finished launching.

[opa334]

As far as I know this is no longer an issue for some reason in Dopamine 2.x, so closing (feel free to tell me if I'm wrong)

[OnesuchDev]

Good to know. I don't use Dopamine myself, but wanted to suggest this idea anyway.

[authorisation]

This still happens to me everytime I update dopamine or do a Userspace reboot. A springboard restart from the Dopamine app fixes it. I am on A14 15.5

[471309682]

据我所知，由于某种原因，这在 Dopamine 2.x 中不再是问题，所以结束（如果我错了，请随时告诉我）

iOS 15.4.1 iPhone 12 dopamine 2.2 happened again.
