Hi folks, first up, apologies for starting a new thread, but i am completely lost and couldn't find any solution online and wasn't sure which thread to post this in. So here is my situation
So, i upgraded my mediapad x1 to 7D-501u a week ago, and it was working well. While on it, i rooted it and did the following tweaks
1. to install google apps i did the tweak at the following link http://forum.xda-developers.com/showthread.php?t=2757537 (which is 1. Go to the following folder 2. / cust / channel / charm_china_u / xml / 3. You will find the file UNSTALL_APK.XML 4. Rename it to : UNSTALL_APK.XML.OLD)
2. I changed the DPI to 400 by changing build.prop
Then, i wanted to give the phone to my sister and did a full factory reset (without undoing the changes above). Now, none of the keyboards work after the reboot, (Huwaei keyboard is all messed up resolution wise, if i choose any of the other keyboards they FC). I tried reinstalling the rom itself, but it give me an error saying unable to mount update.app
Any ideas on how to proceed? I am stuck right now.
Install https://play.google.com/store/apps/details?id=org.pocketworkstation.pckeyboard&hl=en
this keyboard usually works on all dpi settings.

Hi Ashish, thanks for that, but currently i am unable to type anything on the phone that has been factory reset, so i havent been able to setup my google id, havent been able to download anything in the play store etc. I was just wondering if there was a way to overcome that problem of the update.app not being mounted.
When i try to update, it gives me a message saying update file found, but cannot mount update.app
Hi,
Try to connect your x1 to your PC with Hisuite software installed on your PC. If your x1 can connect with Hisuite, you can then reflash your firmware again (I hope).

Are you trying to reflash the firmware from within the OS? If yes, you are getting the error because you have rooted.
You will need to put update.app into a folder named 'dload' then put the folder at the root directory of your SD card, switch off the phone and force flash.
You can force flash by holding both the vol up and down, and the power on buttons concurrently, when you see the screen lit up, do not release the buttons yet, only let go of them when flashing starts.
At the end of the flash, you will / may be asked to removed the SD card (if you were not asked, pull the card out when the phone reboots, else it will attempt to flash again).

Thanks a lot. I managed to install a new keyboard and adjust the resolution and stuff. But i am now not able to upgrade or install a different rom version. Once it enters recovery mode i keep getting this same message below.
ERROR:update_package_exist, /sdcard/dload/update.app not mounted
i tried updating using the sd card, i tried using the hisuite software etc. I undid the unstall_apk xml thing, and changed the resolution back, but still no luck. Any pointers will help

Please Format your SD card as NTFS.AT unzip your ROM from Huawei website.(B010 version recommaded).and gointo systemupdate and selcet local
Intro
This is a guide for people who want to make some modifications to config files, or other files, on System partition but do not want to root their phone or install custom recovery in order to keep OTAs and some apps, which don't play nicely with rooted phones, working. Examples of those config mods could be changing DPI or changing volume levels etc, which you would only do once and forget about it.
While root allows you to do those kinds of changes from within android, this methods would require a PC.
If you are familiar with temporary booting into a custom recovery, skip to step 5.
The usual i am not responsible for any of your actions / bricked phones disclaimer applies.
Prerequisites
- A working adb / fastboot environment. Please use Android SDK, if you installed your adb and fastboot using other tools, things might not work, so please just install SDK, install Google USB Driver from SDK manager, install Platform-Tools from SDK manager (should be installed by default) and then add your sdk platform-tools path to your PATH environment variable to have it available in cmd in every path.
- Unlocked bootloader
- TWRP image for you phone (.img) https://twrp.me/devices/huaweinexus6p.html
Follow the [GUIDE] Unlock/Root/Flash for Nexus 6P for that.
Instructions
Here is an example of modifying DPI. I prefer build.prop method of modifying DPI because using the adb wm density command usually caused some issues for me, but modifying via build.prop didn't.
1 - With you phone ON, connect it to the PC and make sure adb is working by running
Code:
adb devices
and making sure that device is listed
2 - Reboot into bootloader. and make sure fastboot is good to go too. Run commands one at a time:
Code:
adb reboot bootloader
fastboot devices
3 - Place your TWRP image file in some easily accessible folder, for the sake of this example i will use C:\Mods.
4 - Temporary boot into TWRP (we are not flashing it here at all).
Code:
fastboot boot c:\Mods\twrp-2.8.7.0-angler.img
Here is where things may not work. If you don't see your phone boot into TWRP then either your adb / fastboot environment not setup correctly (installed via a tool instead of SDK) or your img file is corrupt.
One thing that works for me when TWRP refuses to boot is to restart cmd and issue the command again this closes and reopens adb/fastboot daemon.
5 - Once TWRP is up on your phone it may display a warning saying "TWRP has detected an unmounted system partition". Swipe to allow modifications at the bottom. This screen may not come up at all.
6 - Go to Mount >>> Tick System >>> Make sure "Only Mount System Read Only" is unticked >>> Press Back button
7 - Back on your PC check if your device is listed
Code:
adb devices
8 - Pull the file you need to modify from system partition to your PC. Please note the direction of the slashes:
Code:
adb pull /system/build.prop c:/Mods
9 - Now you should see build.prop in your c:\Mods folder. Use Notepad++ or something like that to edit the file. Find the line with lcd_density= and change it's value to whatever you need and save the file.
10 - Push the file back to your phone:
Code:
adb push c:/Mods/build.prop /system
11 - Reboot
Code:
adb reboot
12 - Profit.
Hope this will help anyone who is looking to do some mods without installing custom recovery and rooting your phone.
Cheers.
Would this work for adding the tethering bypass line in the build prop?
Yes it will. What's the line again I was looking for it the other day and couldn't find it...
Works are per OP's original post, tested and boosted the headphone volume without a problem.
Headphone path is /system/etc/mixer_paths.xml
So as per OP's example to pull: adb pull /system/etc/mixer_paths.xml c:/Mods
push: adb push c:/Mods/mixer_paths.xml /system/etc
I'm using the OP's "Mods" folder to demonstrate the file path but this may vary on your PC.

You can certainly push the files to system partition and they will retain there after reboot. So if you know which files have to be pushed for SuperSU then give that a go. It shouldn't break anything.
I haven't tried pushing SuperSU files to system partition before so I can't guarantee that OTAs will work after this. The only way to find out is to try it i guess...
Can you run nandroids?
not sure if it's allowed or not.. but with this can i push hosts file onto the phone as well for ad-blocking...?????
I will say thanks now and try it later. These are the type of tweaks I would like to make to my phone. Do you know if changing the DPI cause any stock applications to show up broken like they do on the Samsung phones?

Can you run nandroids backups from TWRP by just booting into it?
okay so after i did this i get the following during boot up
"Your device is corrupt. It can't be trusted and may not work properly". Does this mean i will not get Securty Updates any more? I saw i had an update before i performed this however, now i do not see that update notifications any more.

I got this too when I flashed MOAB via adb sideload. I'm just wondering if the same warning appears with the adb push method. Also, the file's permissions don't need to be set after adb push?
My main concern is if Android Pay still works with the red triangle warning. Anyone?
FYI Flashing back to stock is no issue for me.

I think if you get the latest TWRP which supports decryption of data partition (where all your stuff is) you should be able to back it up.
Edit: backup works on nexus 5 with temporary TWRP boot. Sorry I'm still waiting for my 6p to arrive.

Thanks for trying it out! Sometimes OTA notifications take a little while to come up after reboot. But based on the warning Im afraid that they might be disabled now. It looks like it runs some sort of a check on the system partition to verify its legitimacy. So modifying files would be fine on it using this method but looks like adding them won't work.
TWRP just released their recovery with decryption support so you can just follow the standard procedure or just temporary booting into TWRP and rooting from there which works as well.

On your Nexus5 I assume you are also unrooted? And have you tried a Nandroid restore, booted TWRP, no root?

Thanks a lot for that. I didn't unlock the bootloader. Ugh. Time to start over. To me nandroids alone make it worth the effort.
Not sure my question in subject is clear, so here's the thing...
I have dual-boot tablet with Android 5.0.1 and Windows 10 installed, and the model is Onda V80 Plus (32GB), if that matters at all.
I'm really having hard time rooting this device using standard methods (even with much of background knowledge and experience), so I was about to take a different route.
I installed Paragon ExtFS windows app which gives me read/write access to /system and /data android partitions (which have ext4 filesystem).
I was wondering if anyone knows if it's possible to gain root access in Android just by copying some files and changing some permissions or whatever from within Windows OS?
Basically, for those not familiar with ExtFS app, I can assign a drive letter to /system and /data partitions, and do whatever I want with them just like with any other drive or volume.
I'm aware that modifying ext4 partitions can render my Android OS unbootable, but I have a backup and would like to try it anyway as this is my last option.
When I look into SuperSU.zip file (which I always flashed through CWM/TWRP recovery to gain root access), I see many files which some lengthy script is copying all around, so I stopped after analyzing about hundred lines of code lol.
I really didn't find any method like this on the internet, so I wonder if that's even possible, and if it is, how would I go about it?
Thanks everyone.

Root needs a custom kernel. Not something you are gonna do with a Windows setup the way you have it. Also you will most likely not find anything as that is most likely not an official version of Android as Google doesn't allow dual booting.
Thanks for a reply. But I don't see what does custom kernel have to do with what I try to achieve? If I could, in my Windows environment, replicate the modifications that script inside SuperSU zip does to /system partition, I should gain root access, right? In theory that is, since I'm aware lots of things can go wrong. I was hoping someone could explain a bit what SuperSU script is doing when run inside custom recovery, so I try to do the same thing. Again, if it's possible, and if it's worth the time spent. But I have time, and I'm always willing to learn something new.

what su is doing is pulls the kernel and patches it. root access is defined in the kernel. what itnis doing in system is flashimg just the apk
Ok, I see. So if I ask someone who rooted the same model successfully to send me patched kernel, I could easily flash it in fastboot mode (my bootloader is unlocked). So only thing left to do would be to copy apk inside /system/app, and cross my fingers? I'll post my findings if I manage to do something worth writing about. Thanks.
I have same problem with you. I can't root my Onda V80 plus. I unlock bootloader, flash recovery for my device. Then, i put it into recovery mode and install supersu.zip over recovery. When i reboot this onda, it has stopped in onda logo.

I managed to root my Onda few days after my last post, but forgot to post my findings, sorry. I didn't used any of my hacker's skills lol, but I researched a bit more and found out what I was missing. The same issue is with you, so you have to disable verity before flashing recovery by typing in these commands:
Code:
adb root
adb remount
adb disable-verity
adb reboot
After rebooting install supersu.zip, and the next boot won't hang on Onda logo anymore. Hope this helps you.
btw, note that not just any adb version has verity command line switch. You have to download newer adb version!
Thank you! I trie a lots times, but i can't make successfully!
Basic root procedure would be: unlock BL -> disable verity -> flash (temp) recovery -> install SuperSU
Here are the links containing all the files neccessary for rooting Onda V80 Plus: Mega | MediaFire
Note the ReadMe.txt inside archive. It contains list of adb/fastboot commands needed to be executed in order to successfully root the device.
Thank you very much! I download your file and root successfully my Onda V80 plus! It works well for me.
Hello
I'm trying to downgrade my P20 lite to a lower firmware because dc-unlocker is not working with the last one and I need to unlock my bootloader.
I've no idea if what I am trying to do is even possible, if it is not please stop me!
My model is ANE-LX1C432 (dual sim)
I downloaded an old firmware using the Firmware Finder, it the FullOTA-MF - 8.0.0.111
Here is the first question: I see 4 files, which one do I have to flash?
update.zip
update_data_full_public.zip
update_full_ANE-L21_hw_eu.zip
update_full_ANE-L01_hw_eu.zip
According to here the dual sim model is ANE-L21 but the firmware in that package is only ~117MB so I thing the right one is the one in the update.zip package
Second question: How do I flash it? I tried to open the zip file and put UPDATE.APP file in X:\dload\UPDATE.APP where X is the sd card but the updater says "Software install failed, Get help from http:/www.emui.com/emitiondownlad.php?mod=restore
I managed to open the UPDATE.APP file using HuaweiUpdateExtractor and got system.img and recovery.img and I could try to flash these but I'd love if somebody explains me how to do it
Thank you very much to anyone who will reply me.

My main goal is to install an app as system app
to do that i need root access
to gain root acces i need a custom recovery
to install twrp i need to unlock the bootloader
to unlock the bootloader i need dc-unlocker

As mentioned already, you can't and haven't been able to since Android 10. System partitions have the RO_COMPAT_SHARED_BLOCKS flag set. This is nicknamed the "dedup" flag, and the flag's behavior only works if the partition is read only. Not only that, the flag cannot be disabled due to insufficient space remaining in the partition. The lack of space has the side effect of making it impossible to ever set the partition as r/w.
thank you for the answers. i came from android Pie. so much learning curve & surprises with the 12.
Also wanted this. Thanks to community.
some system directory's can be mounted r/w if you have a root enabled file explorer. like root explorer. im not sure exactly which ones.

define harm?
AFAIK the pixel can always be put back to complete stock by flashing the factory rom back and re-locking the bootloader
Harm means the capability of the device. But got the point. Thanks.
So, did you got the point about harm?
physically no. as for software wise you will need to research.
i don't use my phone to pay for things or banking apps so i have never had any loss of use i find valuable.
security wise if you don't have your phone you don't have any security left anyways.
as for what damage you can do once you mount a system partition or other partitions, everything should be fixable with a fresh flash.
but then you take your chances with anything you do.
If you wanna listen all bulshitt about harm and so on - listen .If you wanna enjoy real root and debloat your phone I can drop to you all files (system,system_ext,product) with rw enable form may 5. Drop request in conversation.
Drop all of the files.
