[REQUEST] Password Protect Recovery

Is there a way to password protect recovery mode? This is in order to prevent circumvention of lockscreen protection should I lose my phone.
Optimally, I would like to also password protect ADB access (and possibly the superuser application), but the recovery mode is a good start.
Thanks!

most people do not know about revovary mod so this is not really an issue and the only security flaw is that it allows usb mASS STORAGE but all some one would have to do is pull ur sd card but there is no direct way to acess ur data from recovery you can just flash roms and wipe the data from the phone no user information is displayed exept if it is pulleed from a nandroid backup but if someone can do that they can get it from other ways and abd requires running the android sdk which again not many people can do and i am not sure if you can pull personal data that way or not and superuser is only used by aplications so your good on that front

Thanks for the link.
I already have Mobile Defense installed.
As this is my business phone, my concern is security circumvention and access to proprietary information via debug on the USB or some hack through flashing.
Does it screw anything up to turn off USB debug (after all needed apps have been white-listed by the superuser app).
no it should be fine to disable usb debuging, just remember that if your syncing you'll have to enable it then.
Moved as not Android Dev.
titianum backup needs usb debugging as well as pdanet

[Q] Stock phone w/root locking up on boot.

Hey all,
I woke up today to see that my phone was locked up. I removed the battery and let it reboot, it goes back to the lock screen I have, shows the time/cell status.
And then it immediately locks up.
I'm able to get it into recovery mode and I wiped the cache, but no dice. I don't want to reset the data because I have some important sms messages that I'd like to back up, but I can't access the data folder in recovery mode it seems.
Is there a way to backup the data folder in recovery mode? Or another way to get the phone to not freeze on startup? I'm assuming something just got corrupt.
I am able to connect to it via ADB in recovery mode just fine, but can't pull my data directory or use the su commands (permission denied).
FYI: Phone is stock, except I did root it.
Bounty: $20 to anybody's paypal account if their advice helps me recover data.
Stock firmware but rooted rigjt? Man this might be a tuff one.

Code:
C:\Programming\Android\tools>adb pull "/data/data/com.android.providers/telephony/databases/mmssms.db" "C:\Programming\Android\mmssms.db"
remote object '/data/data/com.android.providers/telephony/databases/mmssms.db' does not exist
I do have busybox on the phone, but still, I need to get root somehow. I don't even know how I can push an update.zip to the sdcard.
I was forced to reflash a stock phone over this issue, and lost the messages.
Tried to get back at them with dd of the internal data storage, had some messages I composed and emails, but nothing else.
Damn.

Blocked device

Hi
it's possible to download data from Z1 if device is blocked (user password, not pin).?
Thanks
Greetings
I can think of two ways...
Adb interface on PC using adb pull whilst in recovery or booted into system, if you previously enabled adb debugging before.
Backup data partition in recovery like TWRP, then wipe everything and restore it, I guess it might work.
Other than that, you can probably google or search around for more options.

Sort of a bootloop after Android 11 update

Hello guys,
I hope someone can help me with this problem...
So the thing is - yesterday I finally got OneUI 3 and Android 11 update (yay?). But ofcourse as soon as the phone rebooted and optimised all the apps and came back to main screen it rebooted after a minute or so...everytime. As soon as I enter my pin and unlock the phone it reboots after a short period.
The same problem happened when I de-bloated the phone a while ago via ADB - but I then enabled back all the apps except facebook and some "safe to debloat apps" which were not even system apps and it has since worked for almost a year. But here we go again....
I even "re enabled/installed" all the apps I could list in ADB ( so basically all the apps on the phone) and then went to wipe cache - but still no go.
I am also wondering if there is a posibility to somehow mount storage just to copy some files to my computer (which are important, and my latest backup is around a month old) and then I'll gladly do a a factory reset - no problem.
Any help would be appreciated, thanks!
If you're able to use ADB to enable/install apps, then you should be able to use "adb pull path/to/files" to copy the files to your computer. You could reboot into recovery mode and see if your computer pulls up the storage that way too. Also, if you have TWRP, you can use the file system to copy files to an external SD card. So you have a few options to get your files.
You can also create a back-up of specific apps (and their data) using "adb backup -f MyBackUpName.ab com.corp.AppName".

Hello, thanks for the reply and helping out.
But all the commands and stuff is kinda useless because the phone reboots sooner than in 30 seconds after getting to the main screen. When I boot to recovery the storage doesn't get mounted.......
And I would've had TWRP but the phone is still under warranty so that's a shame, because on my backup phone I have it (and so did on all the previous ones) and it would be great. But IIRC if I install TWRP now, the phone needs to be wiped.
FFS samsung, what is this....because I now read a couple threads and posts on social media people having exactly same problem, and some didn't do anything with ADB prior to update. shame...

Root to recover wifi passwords

Hello:
I've had my Moto X4 in service for over 4 years now...long past due for an upgrade. I've finally gone and done it, and have transferred my active service to my new phone.
I was using Google's backup service, which supposedly will sync wifi passwords over, but it did not work (not surprised). My research indicates I need to root my phone to gain access to /etc/wpa_supplicant.conf (a file I'm familiar with on linux).
So, now that I'm not using this phone anymore, all I am trying to do is get the last vestiges of data off of it before it gets wiped and possibly pressed into "retirement service" (eg, wifi smart device interface, child's play phone, etc).
I found many guides to rooting the X4, but they all say you will loose all your data first...That is counter-productive in this case, as the only reason I am rooting is to get a good backup.
Is there a solution to my issue (currently non-rooted, need to retrieve my very long list of saved wifi passwords accumulated over 4 years as an IT tech at hundreds of businesses.....)?
Thanks!

If you go to your saved networks, you can click on any Wifi/SSID name and then press the "Share" button (usually with a QR Code icon). Next, take a screenshot of this code. By using a simple QR Code scanner to scan these QR Codes, the details of the codes will be converted to text. From there, you can clearly see the SSID and password of the network.
You can either painstakingly extract these details (for say, if you need them on a PC etc.), or click on the QR Code icon next to the add network button (recommended), and then scan these images on your other phone, adding them to its list of saved networks.
Note: This feature isn't in every phone, and I believe it's only in android 9/10+ (cannot confirm though)
Yep, not available on this phone (moto X4), unfortunately. I've been missing this repeatedly
This is Android version 9, Google Fi version. Is there somewhere I need to go to turn this on?
I think it comes as a built-in feature. It's included in AOSP android 10+ (confirmed), but some manufacturers, cough cough oneplus cough cough, choose not to add it.
Unfortunately, all other methods of recovery (including apps) seem to require root.
You could try to use the adb pull command to extract the file your looking for from your phone and paste in onto your pc, but I don't have enough knowledge regarding it to guide you on that. It doesn't require root though.
Before you try the adb pull option (as its a bit lengthy and could be difficult for some), try to root your phone using KingoRoot (not to be confused with KingRoot). Try its one-click root app first. It may fail multiple times, but after a couple of tries it should work. If it does work, it won't wipe your data, which is why I'm recommending it.
Unfortunately, Kingoroot apk fails at 90% each time, with error code 0x11DD99. It recommends me try the pc app, which it appears all downloads for it are down/broke, so I haven't been able to get it.
Any more suggestions?
adb pull?
you'll need to look up how it works and its syntax, but it should be able to copy files from your phone onto your pc.
you can also copy files from your pc onto your phone using adb push
i cant really guide you on this as ive only done it once, and that was a really long time ago
To get access to root data, you need root access...
I guess you can root your stock rom without erasing data.
Boot to twrp
Sideload magisk

Otherwise, he could've used the twrp file manager to get the data, even without root.
Apparently it can be done via DroidKit, don't know if that's free though..
