[Samsung Galaxy S9+ Questions & Answers] mekler22:
I've downloaded the update, but now I decided not to install it due to several issues that it will cause. Most importantly breaking my call recording capability. How do I delete the downloaded update, or at least get rid of the notification - without rooting the phone?

thanks!
[Samsung Galaxy S9+ Questions & Answers] YrrchSebor:
I guess a factory reset would do it, but maybe you can try just wiping the cache in recovery? On some phones the updates at least used to be stored there, but not sure.
[Samsung Galaxy S9+ Questions & Answers] mekler22:
Factory reset is not an option. Will wiping the cache in recovery affect any applications installed?

I know where the update is downloaded into but I cannot delete it without root access. And I rather avoid rooting my phone at this point.

It's likely your phone cannot be unlocked if the unlock bootloader is grayed out. You can go to Motorola's site and enter the code from the phone and they will either give you an unlock code or tell you it's ineligible to be unlocked. Here's how to do it:

[General Questions and Answers] gesaugen:
So my GF has doubt that her phone (Samsung A5) has been tapped by her ex BF who knew her phone pass and did take care of all devices they posses

Assuming that is the case, will the factory reset remove tracking software from her phone of will I have to flash her phone with fresh OS to be sure the software has been removed completely
[General Questions and Answers] Droidriven:
If the ex actually did something like that and embedded into the system partition on the device, a factory reset will not remove it.

You would need to flash the device with the firmware to remove it, you may even need to use the "re-partition" option in Odin when you flash the device.

It would also be wise to change the password on her Google account before flashing the device, to be thorough, change the password and maybe even the email/username while you're at it, then go to system settings and remove the account then sign back in with the new email/password, then flash the device, after flashing and booting, sign back in with the new account details.

I would also change passwords and account details for any other apps on the device, such as Facebook, Facebook Messenger, any other email addresses or other email apps and any other types of social media apps or other apps that require an email/username and password. Change any and everything on the device that the ex could have possibly had access to. If she also has other devices or PC's synced with her phone or email, I'd change the details on those other devices/PC's as well. If she has WiFi at home, change its password and maybe even see about changing the IP of her modem/router.

Then, after that, make sure she doesn't click on/open/download anything from anyone that she doesn't know, including multimedia texts/pics, it could be the ex trying to embed something again, opening it will just compromise the device again.
[General Questions and Answers] VidJunky:
While what Droidriven is saying is correct first things first. Has the phone been unlocked and/or rooted? If the phone is locked (*Not tampered) then all of that is overkill. Here's a simple test that you can do to see how at risk you are. Start the phone in Bootloader mode and see what it says at the top. It will either say Locked, Locked *Tampered, Unlocked or Unlocked *Tampered. Locked is exactly what it sounds like, the phone is factory locked. Unlocked again means exactly what it says, the phone is factory unlocked. The caveat is the Tampered. So you can unlock a phone and lock it back which will result in the tampered tag/statement. In which case anything could have been done or undone once the phone was unlocked even if it says locked. If the phone simply says Locked, there is no need to panic and simply factory resetting the phone will erase anything that the ex may have done or installed. If the tampered tag/statement appears that's when more detailed steps should be taken, as described by Droidriven. It is always advisable to change passwords after a breakup even if you don't suspect foul play as a precaution. If she fears foul play Google offers 2-Step verification, which I highly recommend anyway, which allows the account holder to use an Authentication app that randomly generates codes to access the account and also prevents anyone from accessing the account without the users phone in their direct possession. Google also offers security screening tools that allows users to see where they are signed in, when the last time that sign in point was accessed, and the ability to sign out of sessions that may still be active. Furthermore Google offers notifications that will text or email a user anytime a sign-in occurs allowing the user full disclosure and control over their account. Although not mentioned, Facebook also offers similar tools and notifications should the concern arise. First thing first however, find out how to log into your Bootloader and verify if the device has ever been tampered with and then work from there.
[General Questions and Answers] Droidriven:
As far as I know, Samsung does not have bootloader mode, it uses Download Mode, otherwise known as factory mode or Odin mode. It also does not quite display the information that you described as you described it. Some Samsung devices may or may not display bootloader status as "locked" or "unlocked", I've never seen anything about Samsung devices ever showing anything about *Tampered. I've seen devices show "custom binary" or "official binary" and show system status as "official" or "custom", some show info for secure boot, activation lock, kernel lock or Knox warranty void.

But, none of this necessarily has anything to do with whether something could have been embedded into system. You can push things to system even if the bootloader is locked and without "triggering" anything or being "flagged" by the system.

Plenty of Samsung devices have been rooted without unlocking the bootloader, without tripping Knox or Qfuse and will show binary status as "Custom"(the one thing that does show that the device is rooted/tampered but still doesn't necessarily indicate any malicious code that might have been placed by the ex, just rooting the device and nothing else would give the same result), all locks at default status as "locked"(non-tampered) and system status as "Official".

Given that the ex was the one that took care of and managed all devices that she owned, I would just take the thorough route just to cover the bases just because there are so many points of entry that the ex could have set up among all of the devices/equipment that she has.
[General Questions and Answers] VidJunky:
While I'll give you that there may be differing nomenclature for the things I mentioned, I've never heard of anyway to reach the Root of a device without going through the Bootloader and without leaving some evidence. While I cannot find an actual picture of the bootloader screen, in the link below there's a picture of the recovery menu where you can see the second option on the Samsung A5 Reboot into Bootloader. Ultimately it's up to the OP but becoming tech savvy enough to root a device is not for everyone. If the device shows no signs of being rooted, to learn how to root a device just in case seems less than worthwhile. OP you could also try one of the root detectors on the Play Store.

https://www.teamandroid.com/2017/01/28/enter-recovery-mode-samsung-galaxy-a5-2017/
[General Questions and Answers] Droidriven:
This tells me that you aren't familiar with Samsung devices because plenty of Samsung devices have been rooted without unlocking bootloader, I couldn't even begin to count them all. Unlocking bootloader is really only necessary if flashing a custom recovery or custom ROM. Not all Samsung devices are rooted by flashing a custom recovery to gain root. Most of the Samsung devices sold in the US have locked bootloader that cannot be unlocked by any means whatsoever, yet these devices can be rooted. Obviously, they have been rooted without unlocking the bootloader.

Yes, it may have the "reboot bootloader" option in recovery, if selected, that will boot you into download mode/Odin Mode. Typically, what you are describing with bootloader mode applies to devices that use fastboot, Samsung does not use fastboot, it isn't compatible with fastboot, adb works with Samsung but fastboot does not work with Samsung in any way, shape, form or fashion.

And it is possible to root a Samsung device, then install something in system and then remove root immediately after(which means that root checker will not see anything) and it won't show anything in Odin mode, won't trip Knox or Qfuse and still show Official in Odin mode. If it is rooted, then an app is pushed to system then root is immediately removed and this was all done without rebooting the device in the process, then the bootloader, Knox, Qfuse and all that never even detects that root was ever there because it was removed, which means it never gets loaded at boot for the bootloader and other security coding to see that root was there. Some can be rooted and then flash TWRP using Loki without unlocking the bootloader, which "shouldn't" be possible with a locked bootloader, yet, it is done.

I'm just saying, it isn't always as detectable as you imply.
[LG V20 Questions & Answers] Rootabaga:
I have an H918 that is running 10i and is still ARB 0.

I am researching the various root methods and I am wondering if there is any real benefit to staying on ARB 0.

If there is, I'll go with DirtyCow, if not, I can go with Lafsploit.

If I use Lafsploit and flash 10p, and increment to ARB 1, will this come back to bite me in any way?

I don't think I'll want to stay on 10i or roll back to this version. I think I will probably stay on 10u or some Oreo variant.

I would appreciate any input on this.

hello to all,

i have this kind of weird problem occurred with my HP rw68xx series. i received a call from a friend after our conversation was through my phone hangs on and i cannot click any key or ever tap the screen. so i let hang in there for about 2 minutes but when i noticed that nothing has changed i decided to push the reset hole below, after it boots up i noticed that antenna icon above has X on it, i checked on self test and found out that my "GSM MODULE" has failed its test then i ticked on PHONE and it shows "PHONE OFF" then i entered *#06# i was shocked when i saw that my IMEI is "FAILED".

now my question is Is there any way to restore it back the gsm services and imei of my phone? and what are the necessary steps to make it work again?

thanks in advance.. :)

anybody got any ideas? is there not a driver of some sort that can be 're-flashed' on these phones?
[iPAQ rw6828, XDA Atom General] caseyaberhart:
new info:

self test also reports "fail rop1 iocontrol!!!" on the checksum test.

phone will only boot on AC power and battery can be removed and phone still runs!!!! unusual because my other rw6828 will not run on ac alone.

i believe that either the extended rom is corrupt, or there is a problem with the flash chip inside the phone.

it might be time for a JTAGging.
[iPAQ rw6828, XDA Atom General] caseyaberhart:
i've come to the conclusion that it could have a lot to do with extended rom.

is there a utility to flash extended rom via JTAG?

or, can i dump entire rom from working rw6828 and flash to stuffed one?

still no solution

i cannot work this one out on my own, any ideas?

Its suspicious
[Samsung Galaxy S9+ Themes, Apps, and Mods] Wootever:
[MENTION=5576622]amakuramio[/MENTION]

Not sure why the installation is prevented.

The application itself just creates an accessibility overlay and changes the permission for /sys/class/backlight/panel/brightness to prevent access from liblights.

Edit:

Seems like this is the common behaviour for non-playstore apps: disable Google Play Protect
[Samsung Galaxy S9+ Themes, Apps, and Mods] vratnik:
The brightness does not change while sliding the slider, only after releasing the slider. Please fix, thx.
[Samsung Galaxy S9+ Themes, Apps, and Mods] VictoSab:
Can this work on other models (like my Galaxy A3 2017 AMOLED) ?
[Samsung Galaxy S9+ Themes, Apps, and Mods] Wootever:
Unfortunately not possible.

The overlay itself should work on every device, only the brightness slider override that requires root is device dependent.

But this isn't particularly well-working, i will probably ditch this override and just add a widget slider so it can be used without root.
[Samsung Galaxy S9+ Themes, Apps, and Mods] qb74:
So is this root only? Cause I saw my screen change brightness immediately after turning accessibility access on, and I'm not rooted, stock rom.
[Samsung Galaxy S9+ Themes, Apps, and Mods] Wootever:
[MENTION=7900737]qb74[/MENTION]

Root permission is used to prevent liblights (android system brightness handler) from accessing the kernel brightness path (/sys/class/backlight/panel/brightness).

The brightness slider on the notification bar then only modifies the transparency of the accessibility overlay, not the display (kernel) brightness.

Without root permission it controls both the overlay and kernel brightness, but this prevents the pwmfree usage as the kernel brightness needs to be at 100% to avoid pwm dimming.
[Samsung Galaxy S9+ Themes, Apps, and Mods] parser:
Trying out on s8+. But weird thing is, when enabled, if you lower the brightness to 0% the screen becomes completely dark. It should not happen like this, I presume. The app has root access too.
[Samsung Galaxy S9+ Themes, Apps, and Mods] Wootever:
[MENTION=3687397]parser[/MENTION]

The lights service might be different on the S8 and is not correctly halted by the application.

Here is a first version that works without root and only relies on the accessibility service: (link in the original post)

It locks the device brightness at 100% and uses it's own slider to control it.
[Samsung Galaxy S9+ Themes, Apps, and Mods] qb74:
So this version works with non-root? Great! Why does the brightness need to be 100%? From the looks of your graph, all brightness levels seem more consistent?
[Samsung Galaxy S9+ Themes, Apps, and Mods] parser:
Hmm, well than I hope you make this wonderful app s8/+ compatible too :)

Thanks for your work mate. Would love to use it :good:
[Samsung Galaxy S9+ Themes, Apps, and Mods] Wootever:
Only the device (kernel) brightness needs to be set at 100%, at this stage the amoled panel only uses a short 59hz vsync signal (this is the small amplitude on the graph).

Anything below ~95% uses the amoled typical 240hz pwm dimming.

The pwmfree overlay now dims the full kernel brightness by decreasing it's transparency, this is somehow similar to lcd contrast dimming.

[MENTION=3687397]parser[/MENTION]

The new version should work on all amoled devices, although the widget type brightness slider is a bit less comfortable than the android system one.
[Samsung Galaxy S9+ Themes, Apps, and Mods] parser:
Trying it atm, the only down side is, as u said, adjusting the brightness by hand. If I am in a game and need brighter screen, have to go desktop and adjust it :/

Would it have an effect on battery efficiency too?
[Samsung Galaxy S9+ Themes, Apps, and Mods] Wootever:
[MENTION=3687397]parser[/MENTION]

The overlay is managed by SurfaceFlinger and shouldn't cause any impact. The amoled panel seems to work identical with the contrast dimming and i would guess the battery usage is similar, but i can't tell for sure yet.

As for the brightness slider, i think this can be placed on the notification bar instead, which should increase the usability.
