In a bid to improve display performance of my tab S ,
I have tampered with the resolution settings using an app from playstore namely resolution changer, and now my tab S, boots up but with a bunch of failed to load........messages and i cant see anything on the screen.........
i had earlier( before this catastrophe) installed TWRP 2.8.5.0 and made a backup of my complete system....... but however now i am not able to boot into TWRP also. Links to mega.co.nz are not working , therefore unable to download stock ROM.
kindly help me with alternate solutions or working links to stock firmwares......

Only way to get out of that is reflash stock rom, afaik. Samsung GUI cannot handle different DPI and crashes, that is why app individual DPI (with root) ist required. There are a bunch of threads on that toppic...

thanks, just did that and my tab is back to life

That's learning the hard way. I've gone the same route, see here : http://forum.xda-developers.com/galaxy-tab-s/general/dpi-settings-t2833667

I issue the command after pushing files modded / permissions reset, give you an idea if it will work. if not you still have root via command prompt to fix your mistakes. Once fixed the system will boot fine. I find helpful, lot less of kdz restores I do.

To Enable apk_delete.sh add this line to /system/build.prop then add your custom script to Location -> /system/vendor/bin/apk_delete.sh

OP Updated for flashfire & guide

Has anyone tried this?
Sent from my VS986 using Tapatalk

I have. So far its great! I installed flash fire style. Everything went fine. Only thing now is in trying to get advanced calling to work again. I already had it enabled. I did what OP suggested but nothing is working. Other than that its nice to have smart settings!

Did you download myverizon app and then activate hd calling before deleting out of /data/app?
I'll look into this issue in the morning.

All is working fine except hd calling want activate. Downloaded my verizon app and then went to settings avanced calling to activate but get the process.com.Android.settings has stopped. I've done everything from wipe settings and apps to flashing again and nothing helps. Any suggestions?

Just saw your post. Same problem here with hd calling

I'll have a look at the settings.apk does anyone have the stock LGSettings.apk with odex files. I'd have to flash back to stock at this point.

I don't but I've got the stock kdz ready to flash. I'll pull it and send to you then once we get it figured out I'll reflash your Rom .
One thing I've noticed is my hd calling says click here to turn it off although I've verified through 4g Data not working on calls and the hd notification not showing up on calls to my wife that it definatley is not working. I also know that it for sure worked on stock so it's something that's causing settings to stop. Soon as I get flashed to stock I'll upload settings.apk

See the errors now, I'll have it fix soon.

Ok after 2 hours of messing with adb saying my device is offline I give up...adb worked fine but this is the first time using it with Windows 10 so I'm guessing it's got drivers messed up which is causing it to not issue a device authorization attempt which means I can't use adb right now.....
I'll patiently wait for your fix. Thank you for the help

Sometimes I have the same issue with Windows, not sure of the exact problem. But restarting Windows and phone while usb is disconnected ussally fixes the issue for no apparent reason.

I want to know after flashing this img my non Verizon CDMA carrier's 3G settings are gone, and I can't connect anymore through 3G.
It needs 3G settings reprogramming , what could caused this issue ?
Knowing that I flashed 13b KDZ on top of 10B and then flashed another 13B rooted img and nothing like that happened...

Unfortunately I am not a Verizon user, I do use my phone on a Yemeni CDMA carrier called "Yemen Mobile" which it doesn't has any features like HD calling, only 3G network (EV-DO) [emoji3] .
Please tell me what to take a screenshot for and I will be happy to take it.
Thanks

Working great so far. Everything works as of now , including HD calling (Note#1 in thread post#2 worked for me). Great job and thanks again!

build.prop DPI change cause bootloop

I'm on MM 20B now, I'm trying to change the stock DPI from 640 to 540 but the phone goes in bootloop, from there I use TWRP to replace the "build.prop" file with a untouched copy to solve the loop. Now, why is it doing that in the first place. Btw is not a MM problem, I had this problem even with LP roms.

Use an editor that does not truncate the build.prop to a size of maximum 10KB. Most editors do so you will "lose" the end of the file.
Textroider is a nice and simple app to do the task you're trying to achieve :good:

Vibe P1 Custom ROM LED not working

I flashed the official Resurrection Remix [5.8.2] ROM yesterday, and while it works like a charm I noticed my notification LED doesnt work. The LED itself works when charging or on low battery, but doesnt react to notifications at all.
I did try a guide that apparently fixes it by using light flow, however that guide doesnt work for me.
Also, the notification LED control section in the settings app only has the battery control option, not the notification control.
Thanks in advance for your help.

Alright so I reflashed the ROM and tried the method again. Everything is fine until I need to change the text document. There is no way for me to change any settings in the text since they dont even appear.
For example, in notepad++ on my PC I search for led_flash_setting, yet it doesnt even exist. Which means I cant use the method.

Sir, can you upload here your .txt backup file that is working? I can't also find the parameters. Your help is so much appreciated. Regads.

editing build.prop on android 10 final.

There seems to be no way to mount /system rw on Q/10 or am i missing the workaround somewhere?

I don't know how to mount /system rw, but you can use "MagiskHide Props Config" to change prop value.

I noticed this also and just factory reset my phone before seeing this about magisk. I'll try that when I get back up and running.
in twrp is shows you can't mount /system or /vendor
I thought I did something wrong when preserving root through the OTA with Magisk. Must be a new A10 thing??

yes, since Q beta 3, see https://forum.xda-developers.com/pixel-2-xl/help/android-q-beta-3-wont-mount-rw-t3929443
editing build.prop is the first thing I do after root. I need tethering badly.

also cannot do a nandroid backup in twrp because of this.

I figured out if you are rooted with Magisk you can use the prop editor on the terminal. just type props and follow the menus

Hey, I know I'm extremely late to this but I just tried this and it's working for me so far. I used MagiskHide Props Config and a terminal window and I have tethering working again on my Pixel 2 XL. Thank you for your instructions!

Trying to do that right now, can't quite work it out. Did you select option #4--'add/edit custom props'? That doesn't seem to get where I wanna GO, which is adding a line to the default prop. None of the other options looks right

Mejud, Yes, I selected option # 4 and followed what was posted earlier and entered "net.tethering.noprovisioning=true" in selection n- New custom prop. After that, I rebooted my Pixel 2 XL and was able to enable tethering again. I did it so fast that I didn't think of listing the missing steps I figured out on my own.

Finally got it--Apparently I'm either supposed to do it twice (after selecting 'new prop' ) else I'm supposed to hit enter, and THEN type in the line

Glad you got it up and working. Now I'm hoping this will continue to work after updating to December's update. By the way, would you know how to get Google Pay to work? Thanks in advance.

Sorry, never tried it

is the net.tethering.noprovisioning=true prop edit still working on April update? I've tried unsuccessfully with MagiskHideProps. Looks like I was able to add using terminal,but not hotspot. Looking a build.prop in file explorer doesn't show the edit?

It's still working for me, only now I'm running it on my Pixel 3 XL instead of the 2 XL. It was working with the March update and thankfully I didn't need to do anything when I updated to April.

Is it possible to get wifi calling enabled on the Verizon network in the USA with a Google unlocked pixel 2 xl?

I've not touched my phone since doing the Nov 2019 update, now I'm hesitant to

It's always a good practice to make a backup so, God forbid something goes wrong, you're good.

I want to edit the build.prop file and add the below two lines to enable me to add the APN settings on ROG 3 phone.
ril.sales_code=LOL
ro.csc.sales_code=LOL
How can I do it?
While terminal solution seems good for tethering, it doesn't have
the option for a full fletched editing of the build.prop file.
