At the time no. Now that you mentioned it I could not get Wi-Fi to work. But that may have been as a result of depressing the system. Which I also have not been able to successfully do at least completely. Back to the kernel, your idea had worked. I simply took the boot image and flashed it to the device, and all is good. Wi-Fi works everything works. I've even managed to reboot more than a dozen times already without it being rejected as I seen in previous cases when rebuilding it. Mind you this weirdness was coming from all sources including the one available on Samsung open source website. Even in the middle of all this I made shirt that my repo was up-to-date as well as all of my tools and I had everything properly installed. So I have no idea what was causing it and I really don't have a way to tell without going through almost all the individual file which I suppose I could save for a rainy day or two.

Now to the next area of weirdness. Deodexing or the lack thereof. I have not been able to fully deodex the ROM. I can deodex /system/app but doing any other directories (priv-app and framework) seems to make the device freak out too much, especially the Samsung applications specifically the keyboard and what not. So then I have to go through TWRP and manually delete those applications. Otherwise the device will constantly spit up messages telling me "so and so has stopped working". I had tried superr's tool a few times and couldn't get the ROM to boot if it repacked it into a zip. Then tried simple-deodex which worked halfway but I had to manually push /system/app. Pretty much I want to deodex so that Xposed would properly install and work.

Also adbd refuses to go insecure. I've tried everything including using the .pngs from the adbd-insecure.apk. anytime I do that I get the exact opposite effect...plug device in and can only transfer media if debugging is turned off. If I turn it on, ADB says it can't find the keys, but it does work in recovery. Installing the app also has the same effect.

I would love to build a custom ROM for this, but any ones that exist, the audio, video and camera doesn't work. I have a high suspicion the audio and video is a codec problem with OMX. Just finding the right OMX codecs is the problem. We ran into a similar situation with our Amazon Fire HD 10 where when building the ROM, for whatever reason OMX and Google codecs weren't playing nice so they weren't being properly built and placed (another pain in the butt from MediaTek).

I appreciate your help or anyone else's help. I never would have thought of taking the boot image from the factory binary firmware.
[General Questions and Answers] Jochen K.:
Thanks for your swift reply; unfortunately, the reason for my problem turned out to be (I think) a misunderstanding on my side.

I always have "Datenverbrauch reduzieren" (reduce data consumption) activated ("+" inside a circle).

I thought that this only restricted the ability of apps to access the internet in the background; for all other apps on my device that download or upload stuff this seems to be so.

The Play Store, however, can't download at a reasonable speed even if its list of apps to be updated is on the screen.

So nowadays, to update, I deselect the option (no "+"), tap "Download" in the Play Store, get the same download speeds other apps deliver when the option is selected, then I select it again.

Is this a behaviour peculiar to my setup (Galaxy S9 with LineageOS 15.1), or have Google done something I simply don't understand?
[General Questions and Answers] DragonFire1024:
I've been experimenting with ways to somehow upgrade the firmware for this device from Android 6 to Android 7 and I know one of the reasons is because of the boot image. Which doesn't seem to be the case for this device as per another weirdness. There is one other device that is exactly the same as this one and that is one from T-Mobile. Which if I recall correctly did go up to Android 7. Though i am not sure if it ever made its way to the United States. So just like our tablets, when we updated our custom roms to Android 7, from lollipop, we lost audio and video. The same thing happens to this on5 when upgrading the firmware from 6 to 7. In the case of the tablet it was OMX codecs and libraries. Is there any easy way to compare between the two firmwares as to what would be missing in terms of those libraries and what not? I suspect in this case it's not a kernel issue so much as it is a system issue. My issue was coming across the proper factory binary for my firmware which I finally did. But just so you know as well it's a son of a gun that SuperSU won't disable Knox when you flash it to this device through TWRP. It will disable DM-verity but that doesn't do any good when you reboot the device to find SuperSU useless because Knox won't let you operate it. Which now comes the head scratcher why would a phone provider and or OEM offer you a device with an unlocked bootloader and or the option have it oem unlocked properly, go through other such extreme lengths to stop you from even getting there in almost every way possible? I have eventually put many phones aside for this specific reason. It has become a nightmare to actually unlock a device that is already supposed to be unlocked. I'm glad in most cases depending on the device people don't pay for this stuff. I have an old Motorola xt907 which the brand new Droid razr is based off of. It is the only device I've ever had to pay for the bootloader to be unlocked.but I knew the company was legit and they have been around for ages and support numerous other devices (Sunshine s-on/off). But they used actual bootloader code, which they have every single one for that particular device. The phone was made in 2012 to 2013. that's the only other phone I've ever had so much trouble with only because it is truly unlocked and you can truly screw it up, though easily fixable. So I feel your pain with your device as well. Happy and lucky unlocking!

Now one more thing how do I know what sources to build from to re modify the kernel again? Will that even be possible at least to build one with the permissive kernel beyond the factory binary? This is the first kernel I've worked with a Samsung device that builds perfectly even when adding options or subtracting them as long as it has nothing to do with security or selinux. So it would actually be nice to have a kernel that I've built on a device that I can actually add and modify features that work.
[General Questions and Answers] TheInfiniteAndroid:
Feel stupid asking this but here it goes... I have a Huawei P30 Pro, I'm in the UK, I have the power button gesture enabled for Google Assistant so it activates, my question is, why does it say in the Play Store I don't have it installed when obviously I do, is there a difference between them? Should I download it?, Thanks
[General Questions and Answers] Droidriven:
Instead of building from source, between the kernel that you built and the factory binary kernel, maybe you can use the two of them to port the kernel that you built to work correctly using the factory kernel as a resource to pull from or to at least see how it is internally structured to use as a blueprint so that you can make your custom match it in the areas that it needs when you compile the new kernel from source.

What tool-chains are you using? That kinda has an influence on outcome, they each have their pluses and minuses.
[General Questions and Answers] DragonFire1024:
That could be possible. I'm using the standard pre-built tool chain in the Android source code CyanogenMod 14. However I was looking over the Android properties, using settings database editor. I ran into another oddity with selinux again.

ro.boot.selinux=enforcing

I have added to the default prop valued to permissive with no effect. This is an Exynos and so far as I am aware the standard kernel cmdline so in the split image that empty and adding the values there also did not have any previous effect. I also put it in the build prop just for ****s and giggles and of course no effect. I have included two screenshots the first one shows the settings and the second one shows the prop value in settings database editor. I meant this is my first time working with this type so I don't know where they would props for the kernel command line otherwise. I have not been able to find any other references to most of these props until I downloaded settings database editor.

Running getenforce in a shell says permissive but that could all be changed at boot or just after the system is done. Which is where the permissive comes in. I will have to get kernel and system logs from TWRP to find out for sure.

[Q] Mediatek engineering mode MODDING

I just noticed even in same devices. But different stock room version we may get different settings available in MTK engineering mode.

So, the question is, where are them located inside root folder (both LIBS and APK)? Is it possible to copy one room libs & apk to replace current ones in our MTK devices?

Help will be very appreciated :D
[General Questions and Answers] SubwayChamp:
In my understanding not, engineering mode applied to what you are asking is only a door to get access to various tweaks and tests related to hardware but is not an ability itself to do more than device can or allow, some brands blocks the access to it to avoid device get damaged due to a bad or incorrect usage. The way to find an option for what you are trying would be search for some hidden/secret codes for mediatek devices, this to software level or some box to hardware level that allow a lower access. I mean the engineering mode that is available for a specific device is what the manufacturer want to be accessed cause the capabilities permit only that in a specific firmware version/model.

Hi guys i think this is right place to ask but sorry if I'm mistaken.

I have trouble rooting my Motorola Moto e4plus XT1771.

There are tutorials on this forum but they are for XT1770, XT1772, XT1773 etc. but i can't seem to find tutorial for XT1771.

I tried following tutorials from youtube but i just factory reseted my phone and couldn't find proper TWRP version for my phone because it always says "(remote: size too large)"(17mb) so i found random one (that wasn't smart i guess) witch was smaller (10mb) but then i couldn't get in TWRP menu. I was messing around and i got if to reboot but no twrp was shown it just factory reseted.

Can some one send me link to thread that is valid for my device?

If you didn't understand something from above please tell me and sorry for typos.

hello can you help me how to port galaxy S9 system ui to galaxy S8 to have s9 Infinity wallpapers? what files I have to replace?
[General Questions and Answers] DiamondJohn:
If its just the wallpapers you want, then you do not need to port the ROM and it would be overkill for the wallpapers.

Do a search for the wallpapers for the stock S9 and then copy them to some where on your SDCard such as /sdcard/Pictures/Wallpapers

Once they get scanned by the media scanner, they will be available for use.
[General Questions and Answers] SubwayChamp:
As I said you before Engineering/Service mode is an state that can be accessed through many applications that make a shortcut to their controls, you would find this app by default integrated into device usually in /system/app and also you can access to this menu through hidden/secret codes like these https://xdaforums.com/showthread.php?t=2313812 but ALL what is possible to do by accesing this door and changing some parameters is cause is allowed in this specific firmware/version/device. This means that you can´t simply copying libs and/or apks to gain a different menu but you would need to build all the ROM from source. There are many applications in the Play Store that probably can offer a different view to the user like this https://play.google.com/store/apps/details?id=com.Go.EngModeMtkShortcut&hl=es_PY

As you claim that within different firmware/version even in the same device are different menus the short way you should try is by flashing the whole system image from the version desired but keeping updated the other partitions, this can be done through SP Flash tool if your device supports it.

Samsung galaxy J3 Top frp bypass

I have very limited knowledge when it comes to mobile phones. I was recently given a Samsung galaxy J3 Top 2018 (SM-J337V), unfortunately it is frp locked and the person who gave it to me does not have the google account information. I ran an IMEI check and it came back clean. I have done a lot of searching to no avail on finding a bypass for this particular model. I have obtained the stock firmware but it does not remove the frp lock. I was hoping maybe someone has had better luck finding a way around this and might be able to point me in the right direction as this is the only phone I currently own and need to get it working asap. Any information would be greatly appreciated. It is model SM-J337V build number J337VVRS4BSI2 with Android 9. Im not sure how to obtain anymore info without being able to get into the phone.
[General Questions and Answers] ktmom:
This is a grey area for XDA. FRP protects devices that are no longer with the original owner.

The best way, and often the only way, to overcome FRP is to recover the Google account last used with it. If the person who gave it to you was the last one logged into the phone, have them recover the account by going through the recovery process online.

So sorry for not getting back to you directly on this [MENTION=5691352]Droidriven[/MENTION]! I don't believe I have done so.

Please accept my apologies! ?

Yes QPST is mainly a tool for unbricking and flashing phones, however I have came across a (or some) tutorials that uses its toolsets to access some of the hidden partitions.

Very much like in this video, the user uses Partition Manager within QFIL: https://www.youtube.com/watch?v=mHO3PA98qE0

(Please do let me know of your thoughts on this one).

I have previously posted what is "EDL" and "Download" Mode. Are they the same thing or two different things?

I am considering an EDL cable as I don't think I am getting much function through my USB only cable.

Did you unbrick your devices with any special cable or device perhaps?

That might be the absolute last resort that I would have to come to, but I believe at this stage there is still a possibility.

Because the status of my phone when I enter emmc software download app is EXACTLY like this user in the video, however he managed to enter it without problem, I keep getting error message :(

https://youtu.be/vkUv5Wmor8Q?t=41

I am still incredibly new to all of this and trying to understand how exactly the software (namely within QPST) work.

At this stage I'm trying very hard to avoid any type of flashing as it'll result in the wiping of my data, I need to dump this before unbricking and flashing so I can be on the same side!

I greatly apologies if I may have been a bit much, but I am trying to not let my misery and distress stop me, and although I may not sound like it all the time...I always I look forward to your thoughts, especially now after posting this! ?

How to select wifi connection with Notification bar drop down?

- I remember Old android or at least my Fire HD8 gen 7th Amazon tablet (using android 5) have this neat feature

when you swipe down your notification bar you press the wifi icon... i will not turn off the wifi but actually gave you a list of wifi hotspot you can switch to, and yet there's a toggle switch to turn off the wifi.

- This ain't seem like much but this saving me a lot of time, instead long holding it to go to the setting and exiting the current app i use, i just swipe then switch!

- Is there any way to mod around this? ADB perhaps? or a certain app? currently using stock android 1 rom, android version 9 on MI A3
[General Questions and Answers] Raresh T:
Cant recall if i saw something similar around. Best case scenario would be to use an app that gives you that menu. That or finding a custom rom based on your Android 5.0 Amazon rom. Good luck !

Ok so links in that thread are not working anymore and thread is closed so i cant follow that tutorial.

But i found this tutorial witch i followed but couldn't boot into twrp after successful recovery flash.

I just downloaded another twrp for my device from here : https://eu.dl.twrp.me/nicklaus/

twrp-3.2.3-1-nicklaus.img was about 17mb and it was too large for my device so i downloaded older one twrp-3.2.3-0-nicklaus.img

witch worked but after installing Magisk, No verity opt Encrypt,rebooting my device and downloading root check i said my device wasnt rooted.

I will try with different twrp and magisk versions today.

Hello,

i have a Samsung S7 with a cracked screen that is fully dark. The phone does power up, i can call it and get notifications on it but just audio. To be honest i don't care about the phone but there are many photos i would really love to transfer from it. Is there a tool or something that does that? I have found hundreds of pages online claiming to offer exactly that but to be honest i have no idea which one of them is genuine and which one is a rip off.

TIA

[General Questions and Answers] DragonFire1024:
In regards to my Galaxy On5, I discovered something else about selinux. On the Exynos kernels, they don't use the standard way of giving the kernel it's cmdline. In other words, you can't unpack the boot.img and add anything to the boot.img-cmdline because it won't have an effect. However, their is a way to edit it because somehow there is a cmdline. How is this done then?

androidboot.selinux=enforcing
[General Questions and Answers] Droidriven:
I'm not sure that is something that can be edited in the .img post-build. The changes would probably have to be made during the build/compile process.
[General Questions and Answers] DragonFire1024:
I would have thought so but I'm not sure where to even start looking for that because I don't recall seeing any of the command line commands actually existing in the source or being selected. There are options to select and add come on lines to the old style, but I don't recall if I ever tried adding anything to that or not but the box was always empty. I guess I could try but given my luck with other aspects of the security of this kernel, I don't expect I'll be successful at least getting it to boot. But I guess we shall see I will try giving it a shot tomorrow.
[General Questions and Answers] Droidriven:
I'm not a kernel developer, I could be wrong, but, I think it is something that is more java related than it is Android/Linux related. In other words, not something that can be changed via the typical programs used to modify android resources such as C++, text editor, hex editor, etc... Android SDK(which is basically a Java based tool) and kernel source are probably the only tools/resources for the task.

I'd find some of the fora here for some Samsung Exynos devices that have kernel development here, then find some kernel threads in those fora. Read some of those threads or send a few PMs to some developers on those fora. Look in the developer/development specific fora here, they have in depth discussions of various areas of android development, you may find information about kernel modding.

[General Questions and Answers] ktmom:
And connecting to a computer doesn't allow you to use a file explorer to browse the user data where the photos would be stored? You would need the correct drivers for the phone installed on the PC. Also try with it booted into recovery.

You could try smart switch https://www.samsung.com/us/support/owners/app/smart-switch

Or this link gives you a guide to enable USB debugging in while in recovery. I not current with Samsung devices and that thread is older so...

is it safe to use the realme 50 w vooc charger on the redmi note 7 pro which supports 27w fast charge ????

will it spoil the phone ???

i know it wont charge as quick as realme x2 pro , but as I wana use only one charger for both phones ...hence the question
[General Questions and Answers] bharat.bkj:
pasted the image of the realme vooc charger
[General Questions and Answers] ktmom:
Yes, you can use the same charger for both phones.

The charge circuitry in the phone determines how much current is drawn. While not really an issue in this case, the important concern is the output voltage should match and the designed current supply is at least as much as the equipment requires. Watts (w) is related to current if the voltage is identical - so same voltage, higher watts is fine.
