Here's where I'm at. I've got the system to give me the Mount /System option in recovery, now i just need assistance getting the build.prop pulled to my PC. What's the procedure for pulling the build.prop from the Android to PC via ADB while the system is mounted in recovery? Why am I getting one of these two ADB errors?
Error 1: Connect failed: closed.
error 2: Failed to get feature set: no devices or emulators
OR, am I approaching it wrong?
Thanks in advance,
K0mraid3
you dont need to be in recovery to do it via adb....
adb pull /system/build.prop
that will pull it to where evr you run the adb command
which would be
C;\adb more than likely
or you can choose a destination with
adb pull /system/build.prop c:\buildprop
if you create a folder called "buildprop" in the root directory of c:\
at least thats how i remember doing it many years ago, ive been away for a while at her majesties pleasure, so i cant try it currently as im not rooted

Thanks, so far, its still for some reason denying me permission when OS is booted. So i just cant quite figure out where im supposed to execute these commands, is my issue. I can boot directly to BL from recovery menu, but i can also mount system. i think maybe i need sto send command for r/w.. will try that now.
Another question, when i mount /system in recovery, does that carry over on boot?
no you can re mount system via adb though
Code:
$ adb shell
$ su
# mount -o rw,remount /system

1.Needs root for this command. If he have rooted device then why so much trouble needed. Simply use root explorer to copy
2.Since long Samsung have removed system from proc/mounts still magisk system_root can be used
3.Even with system in mounts you can't do system rw on S22 because of Samsung have implemented extra layer of protection. Even not with magisk system_root too
Indeed as of now there is no method available to make stock system/vendor/product/odm rw on S22 even with root access.
4.To copy file from system rw mount not needed, ro is fine

So my device is strange. It doesn't have root, but it indeed shows options in recovery to apply updates from ADB, SD Card aswell as boot directly to BL and to Mount /System, but when I'm booted, the OS is denying me permission to "Su" . I have verified that USB debugging is activated. So I'm trying to see if there's a way to pull the build.prop from Recovery since the Mount /System option is available, but my computer refuses to recognize the device in while in recovery, but easily finds it in Download, BL mode. No FRP lock. No accounts on device. But also no option to unlock bootloader. This device in particular is/was a development sample so I have no clue what the current state of the bootloader etc is in terms of being unlocked prior to me working on it.
It'd also worth noting that this device was loaded with Android 11 when I received it. I'm not kidding. So idk what's going on with this FrankenGalaxy

These options are normal in stock recovery and can be used only for flashing official zip (OTA), To have root access on your recovery, you needs custom one (TWRP) which is in development stage on S22
Without twrp, You needs to root device (must have oem unlock option in development option) to access system files while you are booted to android.
Android 11 on S22? Can you show me screenshot of settings - about phone - software info?

Thanks for the clear answer, that's kind of what I'm working on is trying to gain root access, but like you said, I need oem unlocking, which isn't on this device. So I'm trying to find a backdoor/vulnerability that will take me even one step closer to atleast finding a way to set ro.secure. prop. Something VERY interesting I did find, is that if you put the device to Debug medium or high via device keystring activity, and play with the key combos, you can get booted into a mode called RDX, if you plug it into your dev system with the right drivers, it's treats the phone as if it were a Disk and shows a bunch of VZW upgrade software ment for PCs. I've installed it but haven't got it working quite yett.
No idea what you have shown in screenshot, I'd asked something else.

Just curious, what happens if I follow the rooting steps in the other thread but only do this:
adb push /directory_you_placed_asroot2/asroot2 /data/local/
adb shell
chmod 0755 /data/local/asroot2
/data/local/asroot2 /system/bin/sh
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/bin
cat sh > su
chmod 4755 su
At this point, what state is the phone in? Do I have full root access to the file system? What are the issues/concerns if I don't proceed with flashing the recovery image. Just trying to understand the process and what each step is for. I understand the part above but can't understand why you have to flash a recovery image and can't just use the phone after root is achieved.
Thanks in advance. FYI...all I want to do with root access is delete some system files, nothing more.

You don't have to flash the recovery image. I believe from that code you would have root and can run programs that require root. However, you would be unable to flash a new rom or any other update.zip (which means no auto apps2sd), partition your sd card easily or backup your phone in case something goes wrong. I suppose you are probably just asking for the sake of asking and knowledge but this is why a recovery image is HIGHLY recommended.

thanks. So if I don't flash the recovery image, I can't update to cooked ROMs or do the stuff you suggested but will the phone otherwise function normal? i.e. I can update to a Sprint/HTC update, I can factory reset the phone (assuming that'll kill root), etc.? I may do the whole process with the recovery image later but don't need it right now.
I only need to do this as a stopgap until Sprint/HTC releases an update.

Well, I wouldnt recommend doing a sprint update either. That will cause you to lose root most likely. The only way then to keep root is wait until we get a dump of the update and then cook a rom that includes root, in which case you would need to flash the recovery image. Updates usually fix the exploits we use to gain root.

What he said...but yes, at the steps you quoted, mobilehavoc, you are capable of root access (you don't actually have it until you run that "su" command ). That allows you to read and modify otherwise locked away files and tweak to your hearts content!
Ive rooted and played around some but very little and followed everyones instructions very closely ( thank you for teaching a newbie ). Now how do I go back to original state that I backed up ( think I did ).
When I press the power and volume down button I get to the droid on skateboard, then I press the Home for recovery. I get the screen with all the options and I go to nandroid v2.2 restore and press trackball. It says restore latest backup press home to confirm. I do that and get the following error
Error : run 'nandroid-mobile.sh restore' via console.
What does this mean? Do i have to be tethered to PC and run this command from cmd prompt?
I am now lost again, any help is appreciated

Just to confirm since it wasn't mentioned, you did a Nandroid backup earlier right? can you confirm that there's a folder on your sdcard called "nandroid"?

You must do a backup BEFORE you can do a restore..
To clarify for everyone, here's a breakdown of the steps:
adb push /directory_you_placed_asroot2/asroot2 /data/local/
This copies the asroot2 program to the /data/local folder on your phone.
adb shell
This logs you into the phone. From here on out, you are no longer executing Windows commands from a DOS shell - you are actually executing Linux commands on the phone.
chmod 0755 /data/local/asroot2
This changes the permissions on the asroot2 program so that it can be executed.
/data/local/asroot2 /system/bin/sh
This actually runs the root exploit and creates a file called /system/bin/sh that we will later turn into su.
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
This unmounts the /system partition and remounts it as writeable.
cd /system/bin
This puts you into the /system/bin folder.
cat sh > su
This creates the su program.
chmod 4755 su
This changes the persmissions on the su file to allow it to be executed.

"I get the screen with all the options and I go to nandroid v2.2 restore and press trackball. It says restore latest backup press home to confirm. I do that and get the following error"
Go there but select Backup instead of Restore.
Turn the phone off, hold the Home key, and turn it on. When you get to the screen with the green text select nandroid backup.
so i went into FKU franco kernel updater and changed my CPU max speed from 1500 back to the default but did not change my voltage settings back to default. now the device is softbrocked and just boots to the google nexus splash screen
I have tried flashing:
system.img
boot.img
bootloader.img
stock 4.4.4 kernel
yet regardless of flashing the above the device still is softbricked and wont get past the nexus google logo.
the only thing i have not flashed over is my user data and thats because i dont want to lose my pictures and video of my little boy that i didn't get to back up yet due to my dropbox just hitting its limit.
Im hoping I can remove the franco updater app and its user data and boot but maybe thats not possible?
Thanks for any and all help!

Do you have a custom recovery? If so, use adb while in recovery to pull your files. If not, then flash one then pull them.
Not sure why you mentioned "boot.img" then "stock 4.4.4 kernel", boot.img = the kernel lol
Don't know why your device won't boot even after flashing stock boot.img, but if you use TWRP you can use the file manager to delete the .apk/other files.

thanks, i deleted the franco files and still cant boot.
i want top pull files but it looks like I need ADB and currently i can only get into fastboot mode.
(i'm using wugfresh toolkit, i know some say manual is the way to go but right now this is what I have to go on and have had no issues thus far with it)
i was using the button pull files in the tool kit but its not detecting the device since im in fastboot mode.
i swear I did a factory reset before and my photos were still present but many articles online say in 4.4 that a factory reset will wipe your photos.

It could say "device busy" if data is already mounted. Does twrp have a "mounts and storage" menu like CWM? Where you can mount data? If so, check if it is mounted there (would typicall say "unmount data" if it was mounted, otherwise it would say "mount data" if it is unbmounted)

and then I went back in to cmd prompt and tried mount again and it worked i guess since theres no error. I typed EXIT and was brought back to normal windows command prompt. I then typed
adb pull data/media/0 C:\Users\srobertson\Desktop\Nexus 5 7-15-2014 DCIM
and when I hit enter it just shows a list of ADB commands as if it didnt recognize anything yet when I do ADB DEVICES it shows the device and ID

If you're going to put spaces in your folder names, you'll have to enclose the entire path in "...

adb pull data/media/0 "C:\Users\srobertson\Desktop\Nexus 5 7-15-2014 DCIM"
Best to avoid spaces though.

But I think you guys are able to help me better because I think it's a device/huawei kind of thing, not generally android.
Anyhow, what I did aside from that SE link...
I've downloaded a "template" from here http://forum.xda-developers.com/showthread.php?t=732957, update-apps-signed, and done what he said, afterwards I resigned the zip with SignAPK.
Then I went into recovery and applied update from sd card, but I get the same error every time...
-- Installation /sdcard ...
Installation aborted.
I googled some more and from the looks of it I need an OEM key from Huawei to unlock the bootloader and flash CWM before I can proceed. I seriously hope I don't need to do this.
So here's what tools I got:
ADB accessible phone in normal boot. Phone appears to work, the interface just won't load.
Android system recovery 3e in recovery.
This is incredibly frustrating as I know just changing one bit is all I need to get my phone working again.
Anyone got ideas how to proceed?

Hello,
Since adb works for you. You can try these (One by one)
Code:
adb root
adb remount
adb pull /system/build.prop
Make the required changes which you messed in build.prop
adb push build.prop /system/build.prop
adb shell chmod 644 /system/build.prop
adb reboot
Alteratively, you could register for a XDA Account so you could reply to the threads in the forums as well as get expertise help

adb root -> I can't do that, it says it cannot run as root in production builds.
adb remount -> Not permitted
adb pull /system/build.prop -> This works, that's how I got the build.prop
Make the required changes which you messed in build.prop -> Donezo.
adb push build.prop /system/build.prop -> Read-only file system
adb shell chmod 644 /system/build.prop -> Read-only file system
adb reboot -> Works fine
And yes, I'm op, no idea how to claim the thread or change my name... xda said the mail address was already taken with this username.

I need root access before with ADB if I want to change that, which I can't get. To enable root access with ADB I need to have acccess to my device the normal way and edit the file with something like root ES Explorer. This is impossible as my device is soft-bricked. That's what I think, unless I'm overseeing some things?

Hello,
Well, you edited build.prop and saved that so that would mean you were rooted? Isn't it?
ADB commands work without root. However the /data partition is only accessible by rooted users* and while /system can be read by anyone, it's a read-only partition and root is needed to remount it as writable.

I did that before it was soft bricked with SuperSU and ES Xplorer. I don't know how to use SuperSU with ADB. su -s and su overall appear to do nothing.

It looks to me like the best phone $80 can buy I spent couple hours trying to figure out how to enable Multi User module.
My understanding is that adding this to /system/build.prop would bring users module back:
fw.max_users=3
fw.show_multiuserui=1
None of the commonly used apps can root this phone.
Without root I cannot remount /system to read-write to edit build.prop
Stock recovery can mount /system
There are options in recovery to run update from sd card or to update via adb sideload but the phone does not show in adb devices while in recovery. There is also fastboot option.
I also tried dirty cow exploit but it fails with "only position independent executables (PIE) are supported"
I am into this for only couple hours, so I know I am missing a lot. Any pointers that could get me closer to enabling Users module would be welcome.
So, after some reading, i figured I should be able to apply update form recovery that will replace build.prop with modified one. For start, to test things out, I just want to copy file from update.zip to /system/build.prop.test
I created update.zip with update-script and the file I want to add to /system.
Here is update.zip: www . filedropper.com /update_10
I signed update.zip using this:
www . learn2crack.com /2014/02/sign-android-apk-zip.html
I get error "Signature verification failed". Is the problem that keys are test keys or that they are outdated? Is some special manufacturer key required to sign updates?
I am not looking for someone to do this, I just need to be pointed in the right direction.
I have multiple users now :
- downloaded TWRP from bluroms.info
- connected the phone, enabled USB debugging and OEM unlocking in developer options
- run "adb reboot bootloader"
- after phone booted in fastboot mode
fastboot oem unlock (followed instructions on screen / all data wiped)
fastboot boot blutwrp.img (downloaded TWRP)
- twrp started...
- mounted /system
adb pull /system/build.prop
- edited build.prop
adb push build.prop /system/build.prop
adb reboot
- phone got stuck on logo after reboot
removed battery and started the phone again and all seems good
@sasha_ Hey I know this isn't about how to root but could you tell me exactly how you managed to root your Blu Advance 5.0 HD? PM me.

If by rooting you mean, installing supersu so that apps can request root access, i did not do that, because i do not need it. There must be some tutorial around about installing supersu once you root access to the /system - and the steps I described can you get there.

So is getting root access to system like booting recovery TWRP? then pressing the Mount button and checking System? Sorry I'm a newb at this.
I'd love to gain root on this phone I have twrp installed but can't seem to find a root method that works
Just in case you guys are still watching this, I posted my experience with this phone here
https://forum.xda-developers.com/showpost.php?p=75164672&postcount=26
I bought a phone (ZTE 2050) that has next to nothing as far as development goes. I have tried to install TWRP recovery but it had never actually worked. I have tried using various tools that port recovery to MTK devices. None of them have worked. I have been able to achieve root through Magisk. However, when I do, I no longer have the stock recovery either. There are several other problems that happen as well, but nothing I cannot work around. What could I be doing that is causing me to lose recovery? The chipset is MTK6771 and it is an ARM-V8 64 bit and it is running Android 9. Literally the only things I'm able to find online regarding this phone is the sites that I believe only copy and paste from other phones whether the root method actually works out not. Almost everything tells me to use MTK Tool but that definitely doesn't work. I have issues with Smart Phone Flash Tool working as well despite all drivers being installed correctly. The only way I have been able to achieve root is through unlocking the Bootloader and flashing. And even though I follow the instructions on commands, I still lose the stock recovery. Any help would be greatly appreciated.
Reflash phone's stock ROM.

I have flashed the stock system at least 50 times by now. I have tried flashing everything in different orders as well. When I have root, it always removes the recovery. When I open my file manager, I use Solid Explorer, it tells me there is no root file system. I have tried other root file managers as well. They all tell me the same thing.
Android is rooted if su cmdlet is present in Android's filesystem
I've got a $100 Chinese MTK phone and the one redeeming feature is that once the bootloader is unlocked, you can fastboot over USB (bootstrap).
I used SP flash tool to backup the ROM and WwR_MTK to extract the partitions allowing me to make my own custom recovery to boot with fastboot. Briefly, I found a twrp recovery online for another MTK phone and just played around with zImage & initrd.
Shell commands, dmesg, cat /proc/partitions & blkid on the phone come in handy to track down in partition layout. No need to flash anything so don't get issues with /system/bin/install-recovery.sh

I got it to hang on to the stock recovery. However, the bootloader remains unlocked. If I lock it again in fastboot, it will not allow me to boot the phone. When I try to flash vbmeta, it tells me there is no such file on the system.

I'll give that a shot. I just tried to open my root file system and it told me that BusyBox isn't installed. I thought I had read that BusyBox wasn't necessary with Magisk. Last time I tried to install a BusyBox, it screwed the whole system up. Is there one you would suggest? I've seriously messed with this phone 1000x's now and it's made me giggle shy to do anything to it at the moment.
Some devices have 'toolbox' or 'toybox' as a limited replacement for busybox (ls -al /bin/ls should reveal what binary the sym link points to).
I've used the ru.meefik.busybox app from the play store.

I rebooted and it started acting ok once again. When I tried to open my file manager to access to root file system, this is still the message I got even though I have not uninstalled the BusyBox.

I just opened the BusyBox app and it says it isn't installed even though I have not uninstalled it either.

"cmdlet" not found. Yet Magisk is installed and I am able to access root.
If you can successfully apply su ( read: Switch User cmdlet ) then it got installed by whatever method.

Busybox is just a tool / binary executable command to replace missing
linux commands. You don't need it installed on the phone, just access to the binary to run commands in the shell (copy it from /data/app/....) - its statically linked so should run without issue in the shell.

Ok, I understand that. What I don't understand is why I am now being told that vbmeta cannot be found and installed and my bootloader must remain unlocked. Or why I cannot install recovery without losing recovery.

I just installed another BusyBox and the system is running fine afterwards, but this is the message I get when trying to open the root file system.
