Hello All and Thank you for viewing this Thread,
I work for a Company that configures devices for certain Companies/Clients,
One of our clients is looking to Lock down their Android Device (Probably a Samsung Galaxy Note 8) so that the users can not access certain features at all (This will be done through an MDM and a Custom Launcher). They are worried about the security on the device, they cannot let the users get access to anything but what they give permissions too. One of the major problems with this is the fact that if you boot into Stock Android Recovery you gain access to the Factory Data Rest, which then Completely reopens the Tablet to be used however the user would like.
To the main Questions,
1. Is there a way to Disable/Limit/Remove the Stock Android Recovery Feature so you can not wipe the device by booting into recovery mode?
2. Would this require Root Access (Since Root Access opens up the device even more, we are trying to stay away from this)?
3. I heard there was a Custom Recovery that allows you to set a Password to gain access to the Recovery Options. Is there a way to install a Custom Recovery then re-lock down the device so it is no longer Rooted or other potential security risks?
I think that is all that I can think of at the current moment, if you have any ideas on how to possibly accomplish this please share them.
The client also has custom cases to prevent access to certain parts of the device. Due to the Case and the custom launcher, my only Idea would be to possibly restrict the hardware buttons (Such as the Volume Rocker) to disable access to recovery mode, then have the Custom Launcher/Custom App to give access to the Volume controls via Software.
Thank you for any answers/insights you can provide, and thank you for taking the time to read this thread. Also if you need any information from me please don't hesitate to ask.

I also for a company and we are looking for a similar solution because the users found out what Volume UP + Power Button + Home button really do when pressed together.
I am aware that the user can simply reflash another recovery rom and be able to root the device and do all of that stuff, but it would at least be another step to the less experienced users.
Also I tried to find an recovery rom that would require a password to access the boot menu, but it seems not to exist,
So, is there way to disable the recovery mode or an restricted recovery rom that does not allow the user to factory reset or root or mess up with the device just by pressing those keys?
would really be a good idea

That would be a very good thing for popular custom recoveries like Clockwork Mod and TWRP (Team Win).
simply remove the recovery part
No one has an answer and its 2023?
I have a rooted Pixel 7 Pro and want to disable or lock android stock recovery to prevent theives from wiping my phone and allowing tracking if ever i lose it.
Is there ANY way to disable the power button and volume combo to force power down/recovery?
Or even lock the button combonation?

Hi all a friend dropped her Galaxy Note 10.1 into me yesterday to see if I could help retrieve her password. I tried entering the password wrong so many times to see if forgot password comes up but nothing. She obviously skipped registering with google. She has photos on it that she wants off it. I told her she would lose everything if I reset it and it might be her only option. Can I root it or install Cwm on it or some custom recovery to bypass the password or does it need USB debugging to be turned on which I very much doubt is turned on unless she hit it by mistake !! I came across these methods maybe method 3 might work ? Not sure.
Method 3 (new):
It’s a quite simple method than the other two. By using this method you can crack / unlock both, pattern lock as well as pin / password lock. But before you use this method, your device must have a custom recovery like CWM installed on it. Note that you may also require to root your device just in case if it doesn’t work by having CWM only (it’s a far rare case though). It should work with CWM Recovery alone.
So, lets get started: firstly download a Lockscreen bypass file from the link given below:
Pattern / Password Bypass for Android
Copy the downloaded zip file on your device’s internal / external memory by any means.
Now, boot into recovery mode on your phone / tab. Note that, each device has a different method (key combinations) to get into recovery mode. If you don’t know how to boot into recovery, you can Google it or ask us in comments below (include your device model along with the comment).
After getting into recovery, select install zip from sdcard followed by choose zip from sdcard. Navigate to the file you’ve just transferred on your phone. Hit Power button to select the file and confirm the installation by selecting ‘Yes – Install LockScreen_Security_bypass.zip’.
As soon as installation gets completed, select ‘reboot system now’ to restart the phone.
Once the phone gets rebooted, you’ll see that the pattern / password lock is still there. But don’t panic, just enter any pattern / password and it will get unlocked by itself.
Thanks to XDA Recognized Contributor dr.ketan for this awesome script. You can find his original thread here.
That’s it! You’ve successfully unlocked / cracked the pattern lock of your Android device. Do let us know if you face any difficulty while unlocking the pattern lock. We’ll be more than happy to help you out.
Nobody able to help me before I have to factory reset it any help would be appreciated :good:
Hi.
All the methods that I know of require USB-debugging to be on. Sorry

No problem thanks for the reply. Looks like I'll have to reset it so.
If you can connect with adb from recovery you could snag the files from there. If your on stock recover it can be done but I'm not sure how. Cwm has the option to mount usb

Hi All,
This may not be the correct section for this topic so feel free to move if there is somewhere more appropiate.
I have a GoClever Tab R75, when setting it up i created a new Gmail account and what i considered a secure obsecure password with no recovery options (I know it was stupid).
The device has fully powered down after several weeks and of course i cannot rember the password, I tried the passwords i used on previous devices because they are all simular but tweeked to keep each one fresh. Now there has been too many attempts. Is there a way to do a factory restore, bearing in mind that there is no vilume buttons and the reset button is only a power reset button. I did try flashing the firmware to see if it may lead to a way to access the boot menu to do this but it didn't help and obviously the firmware flash dosn't interfeer with the data partition so the lock is still in place.
I don't know if it will work but i am looking for a micro usb keyboard with a volume button so i can try but don't expect it to work,
Any comments or tips would be appreciated,
Alan
Hi All,
Doing a favour for a friend whose son keeps changing his pin on his tablet and has been changing it so often (to keep parents out no doubt) he has forgotten the pin and cannot get into the tablet.
His father doesn't really care to lose what's on the tablet as it's the kids own fault and has asked if I could restore it to factory.
In trying to do so i have encountered a litany of issues which i will describe below:
1. I have tried holding Volume Up + Power - This takes me to a screen that just says something to the effect of "Fastboot mode" and nothing else and it essentially just hangs there until batteries run out or I hit the reset pin.
2. I have tried flashing it over ADB using my laptop but also no luck as the device is "unauthorized" since I can't get in to the device with my laptop connected and hit the "authorize" button that comes up when you connect to an ADB interface.
This also means I cannot root the device and flash a recovery on to it.
3. They did not have a google account so restoring via the google account is also a no-go.
I'm not sure what other options there are but I find it very odd that there is no way to get around this. I do realize it's a form of security, but this is a legitimate scenario where one needs to flash the device and there is no way to do so. In any case, i know this is a hairy topic so just my .02, dont want to have a debate lol
Is there any way for me to reset this device to factory or at least flash some form of android os on this tablet?
Thanks to all who read and especially to those who assist!
Still no luck, any thoughts, anyone?
for the life of me I cannot put this device into recovery mode.... i've tried all combinations of buttons but at most it always goes into safemode.... i don't feel like there is recovery on this device even though that probably doesn't make sense.. i simply cannot get INTO revovery.
Has anyone been successful getting into recovery on this device model?
Have you tried on fastboot mode? fastboot -w
Hello guyz I have asus zenfone 3(ZE520KL) Indian piece. I want to lock my phone in such a way that even if someone tries to factory reset it (after switching it off and using power button + volume button) would require a password to do so ( I mean that phone should require password/or similar to load the boot file even for the factory reset options or access the adb method to make changes in my phone.).It is android marshmallow original ROM. I am trying to avoid rooting since the phone is just 4 days old and hence in warranty.
(If I have to then I will root the phone but please help me with this and also provide a stock recovery img if it is there.)

Greetings, your device has its own dedicated forum here
https://forum.xda-developers.com/zenfone-3
and this thread here will help root etc if you go that way
https://forum.xda-developers.com/zenfone-3/how-to/tool-zenfone-3-one-click-tool-t3507417
If you lock your phone with a password/pin then even after a factory reset google frp should protect the phone from being used again
Good Luck

1. Do i need custom rom?
no

no
3. Will the android self update as now?
if you flashed TWRP, no
1. Do i need custom rom? No
2. Do i need custom kernel? No
3. Will the android self update as now? depend on your settings
1-to root it the first thing is to have OEM Unlock available and enabled in Dev Options
if not keep the device fully on and with data on dont restart, power off or reset for at least 7 days continuously (or a bit more) and you should have it
if it's not shown dot bother with the rest
2-to have Dev Menu available go to settings >> about phone >> software information >> on build number tape multiple times 10 times i guess, you will have a pop up confirmation
once back at settings menu you will find a new choice at the very bottom "Develper Options"
3-next step with to plug ur phone with PC with usb cable
after installing SAMSUNG DRIVERS & ODIN and downloading TWRP (custom recovery)
in ODIN 2nd tab, untick "AUTO REBOOT" VERY VERY IMPORTANT
chose the TWRP file using AP button/option in ODIN
put your phone in download MOD power off completely >> power back on while holding vol+ and vol- at the same time
flash the file using ODIN to your phone
4- now here is the tricky part
after fklashing TWRP if you reboot normaly you will be locked again and you wont have that OEM Unlock option i talked about and you will be stuck
so, after flashing TWRP, press vol- + power button to reboot the phone
AT THE VERY PRECISE MOMENT WHEN PHONE TURN OFF BEFORE POWERING BACK ON WHEN IT BLINK
RELEAS POWER BUTTON AND VOL+ and PRESS POWER BUTTON + VOL+ AGAIN VERY VERY QUICKLY
if successful you should boot into TWRP directly
5-once you are in TWRP wipe everything then format the device (ALL DATA WILL BE LOST)
of course you need to have the needed files already copied in the SD CARD
from twrp after the wipe and formatiing
go to install and flash in that order RMM_Bypass_v3_corsicanu or RMM-State_Bypass_Mesa_v2
then no-verity-opt-encrypt-6.0
then at the end flash Magisk-v19.3
once its done reboot the phone normally, you will have your phone working as normal
once you are in, install Magisk APK MagiskManager-v7.3.2
reboot again
and voilaaa, you should have root and everything shoul be functional for you
allthow of course I will not be responsible for any kind of software or hardware damage, and certainly not ressponsible for any data loss
as it is completely you responsibility
I would like to attach all the files mentioned above, to help better but dnt sems to find how
so you will have to download and gather them from previous posts
Thank you very much, but i have a question. You wrote this:
"4- now here is the tricky part

so"
I this will happen what csn i do?
The most afraiding thing is to me about rooting if i get a brick.

its virtually impossible to brick samsung devices these days. Well, perma-brick that is. I have spent entire evenings after work bricking phones just so i could figure out what caused the brick and then fix it. the worst thing that would happen if the FRP lock gets enabled again is that youd have to go re-disable it.
i guess i didnt really explain that clearly after re-reading it. So, when he says "stuck" he means with TWRP installed and no method of rooting. The phone will boot normally in the situation described in point #4
