difficulty pulling build.prop using twrp - trying to get miracast to work. - Nexus 6P General

Hi there, i've been trying to make some changes to my build.prop (mainly enable miracast...can't believe they would disable it!) and i've had a rather challenging time.
I am now stuck on how to pull the actual build.prop...when i enter the command i get a long list of ADB definitions but no file - at least not that i could find. I tried a few times, including directing the file to be saved on an empty drive in case i could not see it.
I have unlocked my boatloader and installed TWRP. Mounted the system then gone back and entered the commands in ADB....and i don't seem to be having any success. Any help would be appreciated.
thanks

Why not just edit it within the built in editors in most file explorers? I use Solid Explorer and it allows me to edit at will within the app itself, no pushing or pulling. Of course I back up my current one before doing anything to it

i'm not rooted...and i've read that you don't get OTA updates...and it's happened to me more than once that i have an issue with the phone, and i can't get service because it's rooted...
and i guess i thought it was too much trouble to get rooted, make the changes, and then unroot...but i could be wrong at this point?!

You won't get OTA with twrp either. You need stock recovery.

so i bit the bullet and rooted my phone...i was able to get the build.prop editor to work (at first i did not have busybox which it seems helps apps to realize you have root). So now when i go to unable Casting, i can turn it on from the top right of the cast screen, and my tv appears. I can select it and it starts to sync up...then the mircosoft display adapter shows that it's also trying to sync...and then it times out it seems. I've checked it with my tablet and my wife's phone...both work.
any suggestions?

I understand Miracast no longer works in Nougat. I'm still on MM with my 6P and it works, but if you're on 7, you may have lost that feature.

What about WUGS toolkit? Do you need to re rooted for that...ifnot thats what I always use to edit the prop. So much easier as it has most edits you'll make and you just choose.

you never needed to root i edit build.prop like this all the time
1. boot to twrp recovery
2. go to mounts and select system
3. adb pull /system/build.prop
4. make edits
5. adb push build.prop /system/
idk if your edit will work but thats how to do it without root and for some of the other things said in this topic you can ota in twrp but it will fail if modify anything like you just did

[Q] How to replace a system file using pc connection

I have been searching all morning for the answer to my issue, but evidently I am not using the correct words in my search. Either that or I am the first person to need to do this:
In an effort to try to get Netflix working on my Gtab running Vegan 5.1.1, I have been trying differing edits of the build.prop file. Since Netflix is working on my original version Droid, I have been using it as a model. All to no avail. So, last evening, fully aware that I might brick the gtab and willing to pay the price of a reflash if necessary, I copied the entire build.prop file from my Droid to my gtab and rebooted. Sure enough, won't boot.
I have backups of the original working build.prop but cannot access it by connecting my gtab to my pc through usb. I can access the files on the sdcard but cannot figure out how to get into the system folder so that I can replace the offending file with a good one. I thought that nvflash might be my friend, but after reading everything I can find on that tool it seems that it will just reflash to stock.
I can reflash my Vegan install, and may have to do so....but is it possible to just access the files in the system folder? If so, all I would have to do is to delete the current build.prop file and rename my backup file back to build.prop.
Anyone know how I can do this?
Joe
You can us ADB to push (or pull) files as well as accessing the command line on your gTab. ADB is a development tool, and is part of the Android development kit. You need to install the driver that comes with it, but first you need to edit the .INF file with a couple lines referencing the gTab. You can find additional information about ADB in other posts.
If recovery is working ok then you could reflash your ROM or craft a custom update to replace build.prop.
You could also nvflash just the system partition if you have an image for your ROM.
Lots of options.
Edit: Just looked at the Vegan 5.1.1 supplement update and it has a build.prop file in it. Reinstalling it would likely get you running again as long as you haven't made any other significant changes to the system files. It might revert a few system applications to older versions.
If you have adb set up and working, restoring your backed up build.prop would be trivial job. Let us know if you have adb working and then we can give you the commands you need to use.
As of right now, I do not have adb setup and working. Well, that's not quite true....I did set it up quite some time ago and used it on my Droid. Guess I need to reconfigure it for the gtab and then proceed from there?
Joe
Well, I resolved my issue by reflashing the VegaN rom, all is good now.

Huawei Mediapad / T-Mobile Springboard Discussion

It looks like we have to move our discussion here, so I went ahead and started a thread.
As of now, there is root for the mediapad, but the only way to root the springboard is by flashing it with a rooted mediapad cust.img - which gives you root but loses your 4g.
So for us Springboard users, we either need root or a way to get 4g back if flashing it as a mediapad. Anybody with thoughts or leads or any know-how?
Finally,
Special room for Huawei Media Pad created,
Thanks to TS
I'm very glad,
Now i'm waiting the master in here to modified this device
cause i still newbie
Actually I Prefer The 3G More THan The 4G For Some Reason I Felt 4G Wasnt Stable Enough....So Im Enjoiying My Mediapad In 3G More Than My Springboard In 4G......
from the other thread, Rumbi wrote:
Yap, only thing you have to do is install Superuser and Busybox from Market and copy "su" from /hwcust/oversea_hk/preload/fixed/bin/ to /system/xbin (e.g. with ES File Explorer with root and r/w enabled), and you are ready to go
I've installed SU & BusyBox. I cannot move the SU file over to /system/xbin. A message tells me that I am not root.
However, when I run Root Check Basic I am told I have root.
I ran Root Check before & after I installed S7-301u V100R001C232B012(Root_version) and Root Check said I did not have root.
So the real question is, How do I really know if I have root?
*****
Actually I installed BusyBox Installer. I'm asked to pick a version to install:
1.19.3
1.19.2
1.18.5
1.18.4
1.17.1
None of these will install.
I also have the option to install a "Custom Tune" is there one? I'd gladly pay for BusyBox pro to get BusyBox running
*******
I powered off the device. Put my sdCard back in (the rooted firmware was removed from it). Then installed the SuperUser update from the market.
Ran that - it said everything was OK. Then I forced it to update - it crashed - so I force closed it. I then realized I could not run the original SuperUser app anymore.
Next, I opened up Root Explorer and was able to move the su file over to the xbin. But now BusyBox is not acting right - It said that it was having problems installing, and I'd need to reflash (or reload - I can't recall) the rom.
I'm rebooting, and going to try to install BusyBox....to be clear on which BusyBox..it's this one:
https://market.android.com/details?...t=W251bGwsMSwyLDEsInN0ZXJpY3Nvbi5idXN5Ym94Il0.

Just realized in Root Explorer, to tap the little gray box at the top. After you tap it it should read "Mount R/O"
Now you can long press a folder/file and change the read/write permission.
Rumbi,
You said to r/w enabled the su file....is that check ALL the boxes?...Read, Write, Execute Special?????
IIRC, i had some problems with busybox, too. Copy the file from the attachment to /system/xbin and try the installer again.
And i said to enable r/w support for the /system folder. There are two checkboxes in ES File Explorer. First checkbox is enable root permission for ES File Explorer and second checkbox is "Mount / and /system writable".
Now you should be able to copy whatever file you want to /system/xbin. That's how i have done it. If you have any further questions, feel free to ask. I'll try to explain.
PS. You don't ne to alter file permissions of the su-binary but mine are "rwx r-x r-x".
Rumbi, how do you feel about the High resloution mode, does it slow the tablet down? Have you had a chance to use any tegra 2 devices and if so how does the mediapad with the snapdragon compare when in standerd/high-res mode?
Nothing to complain about the Hi-Res-Mode but i don't have any Tegra2-Devices to compare, sorry.
Haven't tried any games in hi-res-mode but normal usage is just fine.
Thanks. Ill try this out. When i try to install busybox it hangs first, then i force close and run again. Then i get the message about reflashing Rom. But i know i have root. I installed connectbot and ran su and got #
Heres how i got root (im away from my pc right now so i try to be as accurate as possible) :
Installed Hauwei modified rom (its the one that says "(root) " in the file name.
Installed Root explorer
Installed Superuser
Install busybox
Install Connectbot
Put my microsd back in (with the firmware AKA dloa folder removed)
I could not get root explorer to allow rw permissions until i slid the sd card out and back in whil the device was on.
Then i ran connectbot as local and typed su hit enter then superuser popped up asking fo allow connectbot to access. Hit allow an type su hit enter an you should get # This took 3 reinstalls of the firmware to work wjthout errors. The first times resulted in superuser needing to be force closed.
I also ran superuser and went into settings and updated it eventhouh its not neede. There i got a read out saying that busybox is not installed, but it does say i have root.

Honestly i havent noticed a big difference between high resolution an standard.
The only issue with high res is the small icons and buttons are difficult to hit sometimes

Do i need to unzip this file first?....
.... Nevermind... I unzipped it and put the busybox file in th system/xbin folder.
I installed busybox installer by JRummy16. This time and it worked!!!!!!!
Now its on to figuring out 4G and tryiying to use it as a phone.
What is the xml file i need to edit?
Sent from my HUAWEI MediaPad using xda premium
Good, that you have worked it out now What exactly do you want to do? To get to the hidden menu, you have to open the calculator and type: ()()2846579()()=
To edit the XML-Files, you have to extract the cust.img... But now that you have root, yo can edit whatever is available via root explorer
€dit: To get 4G working again, maybe with someone with an original Springboard (not a flashed one) can copy the folder /system/lib/. This should be possible even without root. I think it has something to do with the ril-files...
after updating my mediapad to S301uV100R001C232B012, i have problem with 2x Client (RDP client) now, few second after conecting to rdp session, is app 2X client crashing, with error 2x Client has stopped unexpectedly (process com.tux.client), is here anybody with this problem? thanks...

Even though I have no clue of what to do with this, THANKS! I tried to open an .so file in notepad, but no luck, but I'm assuming that the geniuses here know what to do.
On an off-root topic - How do you take a screen cap? I accidentally did it yesterday while my MediaPad was lagging, but don't know how I did it.
The Hi Suite that comes with the device can do this, but require a computer and usb hooked up. Useful, but not as practical as doing it from the tablet itself.
The *.so files are a bit like drivers for the internal components. I'll try to find differences between T-Mobile and Huawei so maybe we get 4G working again.

I'm not sure how to screencap. It's so easy on CM that I've gotten lazy. Plus I rarely do it. I know there are a ton of apps for that, tho. But you could probably google "gingerbread screen capture" and find a better answer. But not with gingerbread. I'm blanking on the name for this version of android.

Honeycomb
I've been Googling searches like that, and end up with actual screen shots of Honeycomb os..I'll keep looking...
Tried this (from here), but no luck:
Screen capture
Android natively supports the ability to capture a screenshot by method of pressing both the power and volume-down buttons at the same time on an Android device. This native support was first included within the Android 4.0 (Ice Cream Sandwich) update, which is first seen on the Galaxy Nexus smartphone.[86] Previously, Android did not feature native support for screen capturing which would have likely been due to security concerns. Furthermore, prior manufacturer and third-party customizations as well as using a PC connection (DDMS developer's tool) were the only known methods of capturing a screenshot on Android.
I've looked through the *.so files and many of them are exactly the same, but some are different. One file caught my interest. I've attached it here for anyone who wants to try. Please only use it, if you have a T-Mobile Springboard with flashed root Firmware. Copy the content of the zip-file to /system/lib and overwrite the existing file. But make a backup first! After copying you have to set the correct file permission (rw- r-- r--) and reboot the tab. Hopefully 4G works again with this little trick.

[Q] Hosts file corrupt?

Hello everyone,
I use an LG Optimus L4 II (e445). I rooted it but then decided I had too much on it and decided to restore to factory settings. It all worked fine. However, when I got to the Google Account sign in page, it gave me the "couldn't establish a reliable connection to the server" error message. I followed every single tutorial I could find online as to how to solve this. None of them worked. Eventually, I re-rooted it (using VRoot) and managed to download an apk of ES file explorer and locate the hosts file. This had one line that shouldn't have been there:
127.234.104.240 android.clients.google.com
From what I can make out, this is the address of google's sign in servers. So somehow (I suspect malware/dodgy rooting program?) my hosts file has been edited to stop me logging into google. Restoring the device does nothing, neither does unrooting/rerooting. When I open up the file in ES (when rooted) and edit out the bad lines, I can't save for some reason- I think the /system folder is write protected.
So I tried to make the /system folder writeable. I used the android sdk to do this (mount -o command) but this did not do anything. I downloaded the mount /system apk and installed that, it did not help either. I tried /pull and /push on the hosts file to edit it and send it back using the apk. I could successfully pull and edit it, but it would not let me push it back. I'm kind of stuck here. I can effectively not use my phone- I can't use most apps and can't download any, and have no other solutions up my sleeve. Any ideas?
Thanks a lot,
Louis

After trying for a few weeks now, I've still had no success. One idea has come to me though- installing a rom. Would downloading a custom ROM change my hosts file? Also, if so, could anyone recommend one that is similar to default android? One last idea that I've got at the moment is sonehow completely wiping the hard drive of the phone and reinstalling androud on it, though I have no idea whether that is even possible, and if so, how to do it. I would really appreciate some help here!
Thanks again,
Louis
After reading, I can only talk as one who knows less than you.
Let me say this from the start.
Root=/= unlock bootloader
Find a way to unlock boot loader first, with a Google search.
Use fastboot to flash a recovery (.IMG) made for your phone. fastboot is something like adb.
Let's just say that that is more complicated than rooting. It gave me a headache at first.
_______/
Pertaining to your problem, how about a reflash of the system image?
The official lg mobile support tool may help you with this.
Search for your phone model on the lg support page, look under manuals and downloads, then under software update.

I'm not entirely sure I understand you here, but I'll try. What would unlocking the bootloader do to my phone? Would it enable r/w on the system folder? Also, what is a reflash of the system image? How would I do that?
I'll try these things if I can, but would still appreciate help.
Look around on http://wiki.cyanogenmod.org/w/Basic_concepts?
It should give you some info in flashing and unlocking.
It can give people quite a headache, with all those terms.
________
As for the part under the line, I'm talking about a restoring of the phone to the default state via official methods.
Instructions would be given by the official support programme.

Ok, so from what I can work out, cyanogen does not support my device. Would doing it for a similar device work? Are there any ROMs that support my device?
under the line, restoring the phone via the official ways actually just wipes the user data, not including the HOSTS file which is what I need to wipe. What I really need it is basically a ROM that completely wipes my phone and reinstalls some version of android.
Any other ideas?
While there may not be official support for a phone for a custom ROM, you may be able to find unofficial ports/versions if you search for it in the forums.
From what I know, a system reinstall via official methods wipes data and almost everything else, then downloads from its servers system files to be installed to the phone. At least, my phone was reverted to a stock ROM when I restored it after using a custom ROM. It may be different for some, but generally, this is what I think.
Important: only use a ROM made for your device model only, do not use the ones made for a similar phone, the small differences are no longer small in this case and will cause a system error(?)
Generally, once you have successfully unlocked boot loader using a method for your phone, the instructions afterwards are generally the same for all phones. You'll be able to get better answers in the threads specifically for your phone, so try to look for one and look for the already tried methods,
Here's one:

Enable multi user / guest account feature on Lollipop

The multi user and guest account feature is not available on either of the two recent releases of Lollipop for the Z3v. I did some research and it appears this is the case, not only on other Verizon handsets like the Droid Turbo and the Galaxy S5 / S6, but a few other non-VZW devices as well. I'm not sure why it was removed but apparently it's just hidden. It can be enabled and I followed the instructions for doing this for the various other devices and can report that it works for our Z3v (see attached screenshots).
I've kind of cleaned up the instructions and put them below. Usual disclaimer - I'm not responsible for anything that may happen to you or your cat if you choose to do the following. You DO need root access to edit and write to the system file.
** To be safe, please make a backup of your phone and/or a copy of the build.prop file that you are going to edit.
Get ES File Explorer. Run it and enable Root Explorer setting. (You may be able to use any file explorer and editor with root access but this is used most in the instructions and works.)
With ES File Explorer, go to device/system/ and find the file: build.prop
Choose to edit it with ES Note Editor.
Scroll to the end of the file and type in the following:
fw.max_users=5
fw.show_multiuserui=1
Save the file.
I'm not sure if the next step is required but it was in half the instructions I saw, and I did it myself: Click and hold the file, go to Properties, and then change the permissions to Read, Write & Execute. [all three]
Reboot your phone.
When you're up and running, access multi user mode by pulling down your notification shade and then clicking on your user icon at the top right corner.
Notes so far:
A guest user does not have access to the original user's files on the internal drive - the guest user has their own file directory. The guest CAN access the External SD Card, though.
Therefore, an app such as Movie Creator can and will create a "highlight" movie that is composed from photos that are saved on the external SD Card. Just keep this in mind as far as privacy.
There is a per user option that lets you decide whether or not the additional users can use the phone and access the text messages. If you disable this ability, while they cannot open the phone app to make a call, the CAN receive an incoming call.
You can find out more about the nuances of additional users with your Google Fu.
Enjoy!
Wow! Great work!

Thanks! I really wanted this feature and it seemed like not many people care too much about it. It's my way of circumventing the awful permissions control we currently have in Android. That is, there are apps I want to use but refuse to install because of their overreaching permission requirements (contacts, etc) and so I can now create a second user with a new "dummy" Gmail account that has no sensitive information and install these apps without worrying.
By the way, something neat I figured out about this. Additional user accounts are not allowed to side load apps (the toggle to install from unknown sources is grayed out). I figured out that if the main user / owner restores an app through Titanium Backup, any other currently existing user will have it installed for some reason. I don't know why this happens but it's a neat glitch that gets you around that restriction.
Well I think most people simply don't let others touch their phones and so don't have a use for multiple user accounts. I find that my phone, as big as the screen is, is becoming more and more of a computer / tablet replacement. I like the idea of a multiuser functionality, but mostly to hide my own stuff. I'll silk never let anyone else touch my phone!
The use for multi-user that I've seen that makes the most sense is people with children. They will create a user profile for the child so they can't get into any of the parent's stuff or settings. That or the guest profile which will let them do whatever the heck they want without screwing up the phone.
Aside from that I have read that devs find the feature very useful for testing. Heck, that's not a bad idea to install and test apps, in general.
uh oh.
Well something didnt work. Maybe a certain build I have to be on or what. I followed the instructions to a t. Now stuck on endless boot loop. Only bad part is I'm on as hotel room working out of town without a laptop Or pc to fix it. I used a one click root just today and didn't install a proper recovery. Any thoughts

I had a problem with this also twice cause I'm always doing stupid things to my phone my guess is you didn't change the system to r/w but modified it anyway or you used a editor that would let you input the correct values I used s manager I think. As far as getting your phone working you could try safe mode or maybe a factory reset if you can hold power and the volume button down and enter recovery.

I believe the mistake was made when i changed the permissions per instructions. I finially got to my house and im using adb to freeze the loop then going to push a script over to fix the permissions. I will update when i get it done and I will post my fix. Also I used ES file explorer, which i have already used it for years now. Never had anything like this happen before. it just baffles me. I have never got any instructions off of XDA that led to any malfuntion of my phone. But oh well, sh!+ happens.

Hey! I'm so sorry! I got a couple of new phones (Droid Maxx 2 and LG G4) and have been using those phones so I haven't been checking these forums like I was when I just had the Z3v. Really sorry to hear that you ran into that kind of trouble . Thing is, the instructions above are culled from 4 or 5 different sets of instructions for various devices that I found across the web. I performed them step by step myself while cross referencing them to each other and combined them all to the instruction set above as I did it. Did you ever fix it with the method you mentioned? I'm curious if it was the permissions thing (odd, because it worked for me).

it is guys if done right your system needs to be switched to r/w then go back to r/o after modifying the build prop if you modify in r/o you will get bootloop to a hard brick it depends.

Well I kinda fixed it. I went and bought a HTC M9. Lol but not yet, I'm still working on it. I have found scripts to run, even a specific build.prop fix to push, but I have windows 10 and couldn't get adb to find the device. Plus I'm a little rusty. So I broke out my old windows 7 laptop I have used just for rooting an modding phones and tablets. I did get adb and fastboot to find it once. Then some reason lost it. I didn't have it ready to go. But I'm almost 100 percent sure I can get it. Just need to play around with it a little bit more. Having trouble with drivers etc. I will let you know when I have it.
And didn't really hurt my feelings getting the phone I truly want. I never had problems with HTC since I was flashing roms on my old window phones. I just want my pictures I cannot replace.
"Run it and enable Root Explorer setting. (You may be able to use any file explorer and editor with root access but this is used most in the instructions and works.)"
Alas- I am not rooted, and therefore can not enable "Root Explorer" option. Unless someone has some other suggestions- I think I can't do this unless I'm rooted.
Well this is probably what I did to brick my first z3v.
I don't suggest anyone do this at all. There does seem to be an issue with the permission setting on the build.prop file. If it's not reset correctly after editing, you'll get stuck in a loop or worse. I'm stuck in bootloop, but can get into recovery. I made a backup hoping to learn how to edit the build.prop (delete it and rename the copied original to set it back as it was). But I can't even run the original zip that GigaSPX made up for us. (I don't have a backup like I hought I did.)
Anytime I try to install the flashable prerooted zip it tells me it's done after 2 seconds and says;
set_perm: some changes failed
I'm typing this on my z2 tablet, which has the multi user feature enabled. I'm going to see if RootExplorer will give me some clues as to why this doesn't work.
In the mean time I'm hoping someone can help me out?
If love to get this feature to work, but it has to be safe.
Just checked the build.prop on my tablet and got no clue.

a backup usually means going into your twrp and hit the back up button and make a copy of your system including data and all that. This is mandatory before messing with the build prop. If you want Pm me your build prop and I will send it back to you. With multi user enabled.
Yup, I know what a back-up is and how to do it, and I know it's a must before messing with the build.prop. I just really thought I had done it recently...
-and I had! But I forgot that a few days ago I bought myself a Christmas present; a 200 Gb micro SD, and copied most of the contents to the new card from my old one. I chose not to copy the backup because I had planned to make some changes and create a more recent backup. Never happened though because I got side tracked loading music and such. Lol!
So I'm all back together, but would still like to play with this feature. So I'm going to give it another shot.
A guest user does not have access to the original user's files on the internal drive - the guest user has their own file directory. The guest CAN access the External SD Card, though.

Perhaps the wrong thread but: enabled multi user on a Cube T8 only to find that guest and other user can access INTERNAL sd but not external sd. I'd rather have it the other way round. So the kids (other users) can use the whole of 32 GB sd card rather than me having to share the small internal sd with them.
Any ideas how to fix this? Phablet is not rooted btw.
got bootloop..... but i'm safe as i've backup.... through recovery..
I've inserted two lines and fell in bootloop
Thanks bro.. working....!!!! but second step is not needed...

How to fix the phone that can't login coz its system attributes has been changed?

Hi Everyone,
I have a phone, the Huawei Ascend P7 -L10.
Some weeks earlier I tried to install Spotify in my phone, but I didn't manage to install it. After several attempts I end up crocking my phone.
It happened when I found some app that had apparent solution to solve Spotify installation problem. I don't remember the name of the app. Anyway, I found it effective so I tried to follow the instructions given. I made it, then the changes were effective. What the app does is to change the phone model and respective carrier.
All the dilemmas started when I decided to restart the phone.
Here goes what I've done so far after the incident.
1. I tried by myself to restore/upgrade the system. I've experience doing this.
2. I took the phone to the 1st Repair Agency - they did not fix it
3. I took to the 2nd Repair Agency - the same thing, they fail to fix it
Note: When you try to restore the phone it gives the following information “update failed!"
and when you normally try to switch the phone on it stop on black screen and nothing else, I've also tried wipe cache, wipe data everything but nothing. Please help!!
Sounds like it might have modified your build.prop (general explanation of build.prop is here: http://forum.xda-developers.com/android/general/explanation-build-prop-values-t3069341). Basically this file found in /system dictates a lot of settings and modes for the phone to do and be in. If you are rooted, then you can view the build.prop with a build.prop editor, text editor, or root enabled file manager. If you aren't rooted, then you will have to see if there is a way to install TWRP recovery or you might be able to use adb if you can still get into your phone's settings. With adb, you should be able to pull the file to your PC then edit it back to the correct info. You might need to see if you can download a rom that will have this info or get someone in the forum for your phone to post it so you can verify that everything is the way it should be. Once that is done then updates should work again. Reason being is that most updates reference the build.prop to make sure it is installing to the correct device to avoid major issues.

Thanks for your replay. My device is rooted one, but the problem is, I can't login not even connect it via cable (using e.g. HiSuite). So, how can I pick up the file from phone?
