**Problem** I want to install Android in a VM to restore a backup using Titanium Backup. For this to work, I need Android to be rooted. **What I tried** I've tried to install Android-x86 4.3 in a Virtualbox VM. The installation seems to work. I made an 8GB partition disk (sda1), made it bootable, and installed Android in it from an ISO file. This all seems to work. Android starts, I can browse the internet, install apps, etc. Then I want to restart the VM, and guess what?! I go back to the installation screen, like starting up from the ISO live image. For normal stuff, I can make a snapshot, start that up, and do anything. My problem is that I need root permission to restore a Titanium Backup in that VM. And I cannot root this VM because the disk is not writeable. With Alt-F1, I become root and I can use a script to root Android. But my guess is that I'm still on the ISO and that is not writeable. **Update - another try with Android 4.2** As mentioned in the comments, 4.3 would have problems with root access. I tried 4.4, which didn't start at all. Then I tried 4.2, which has the same problem as 4.3 for me. I made a screenshot of what I see when I try to run the rootscript , which is described here . You can see the errors: **rm failed - Read only filesystem** How can I fix this? **My question** How can I install Android permanently on this VM, so it can reboot and then be rooted?

I'm trying to root Samsung Galaxy A03s (Tracfone, SM-S134DL) with Magisk and can't get it to work without the OEM on in the developers option. How do I turn on OEM?

I am trying to root my Samsung Galaxy Ch@t GT-B5330 (4.1.2) following this guide. I have reached the point when I am intended to use the recovery mode menu (that is reached by holding volume-up when turning the phone on) but here am I stuck: whatever I choose gives me the error icon I am still able to boot the phone the normal way (though it has became a little bit slower than it was before flashing and starts Firefox on itself occasionally). How do I finish the rooting process?

I recently flashed a custom ROM and rooted my Redmi 7A, and now each time I try to connect to a network from a TP-Link router, it just says "Check password and try again," even though I insert the correct password. Also, before rooting and flashing a custom ROM, it worked just fine, and I have tried multiple ROMs, and it still doesn't work.

My android device CPU is MT6592 (8xARM Cortex –A7@1664 MHz) with instruction set 32-bit ARMv7. Board and product is ht1_107a_iball_mjk. Apart from this, Codename is REL, Internal Memory is 16GB and RAM is 2GB. I did root and un-root my device multiple times. I see connected device through **adb devices command**. After **adb reboot bootloader** and **fastboot oem unlock**, I confirmed on android device by pressing Volume Up key but there is no change on device screen and computer screen even after 30 min. I changed USB cable and USB port. However, there is no change. Therefore, I am not able to unlock its boot-loader. After **adb reboot bootloader** and **fastboot flash recovery twrp.img**, I found No TWRP or other Custom Recovery images are compatible for my device. Therefore, I am not able to install Custom ROM as well. I tried all above procedures multiple times and with multiple ways. However, at the end I am with Stock ROM (Android 4.4.4). And only two processes I can do successfully; rooting and un-rooting. In such scenario, may my device be hard bricked, if I continue above processes multiple times forcefully?

I'm attempting to root a Samsung Galaxy A20s (Android 10). I've already patched the boot image with Magisk and enabled "OEM Unlocking" in Developer Options. I ran

adb reboot fastboot

However, when it reboots, fastboot devices shows no devices. Looking online, I found the odin4 utility and attempted to flash the phone by

tar cf boot.tar boot.img
./odin4 -b boot.tar

However, it failed with

How do I unlock the OEM?

How does one root a Samsung Galaxy S II GT-i9100 (with its original Android 2.3 Gingerbread), preferably under Linux Mint? This questions pertains specifically the GT-i9100 version (not GT-i9100G nor GT-i9100T, et cetera), which currently has no entry under the rooting index . I am particularly looking for a rooting method which does not wipe the data on the phone, as [I am hoping to recover data afterwards](https://android.stackexchange.com/questions/89133/data-recovery-on-boot-looped-samsung-galaxy-s-ii-gt-i9100) . I have an 8GB external SD card.

Just under a year ago, I changed carriers due to carrier unlock policies. The provider I switched to I was able to get the Pixel 7 Pro on a payment plan (2 years). With it being a Pixel, I thought at the time all Pixels were OEM unlockable. Man was I wrong, not only am I stuck paying off this phone for 2 years, but without carrier unlock first that can't happen. I know in every other device that If I issued a certain adb disable command, it bypassed that. Is there not something similar I can do to get OEM unlock without carrier unlock? Any help is much appreciated.

Seems I have searched vastly across the internet to no avail. So far, I've tried using a CF-auto-root file with Odin 3, and vroot, neither of which worked. The only helpful thread I've found was an XDA thread from may 2015 which still did not seem to help http://forum.xda-developers.com/galaxy-alpha/help/want-to-to-root-alpha-sm-g850a-t3107199/ The only other resource I've found were several forums and websites that link back to the same blog that claims to have rooted the phone, but the download file is labeled as malicious by chrome and there is no conformation by anyone that it actually works.

I've been looking to root my LG G2 phone (AT&T LGE LG-D800), but all methods require installing binaries from little-known (by me) sites with no Web of Trust rating. I feel hesitant to do that. Here are some rooting links I found for my phone: * https://forum.xda-developers.com/showthread.php?t=2448887 * https://theunlockr.com/2013/10/25/root-lg-g2-versions-video/ * https://web.archive.org/web/20161224210036/https://wiki.cyanogenmod.org/w/Install_CM_for_d800 requires ioroot: https://forum.xda-developers.com/showpost.php?p=48709232&postcount=869 The latter one refers to Kingo Root (its Web of Trust says XDA does not recommend it until it goes open source due to some suspicious activities, such as sending IMEI to the server) Which of these is safer than the others? Also, there was a manual way to root via ADB, or if there was source code, or if there was a reputable, trustworthy site to download from, I'd be feeling much more secure. I am a Java developer, new to Android development, but it's something I want to learn, so programmatic solutions are welcome.

I have a Samsung Galaxy J2 Ace, running Android 5.1.1. I want to root it now, and I have installed its respective system firmware from Frija. Initially, I followed David Bombal's tutorial on how to root Android (he used Magisk), but later found out that it is only supported for Android 6+, and so it is not applicable. I have tried Kingroot, Kingoroot, SuperSU, Magisk, Ding Dong Root, etc., and none support the device. I decided that if I unlock the bootloader and then upload a custom ROM using Odin, the phone might get rooted. Just asking if this technique will work. (I am a Windows/Linux user and don't know much about rooting, just had a useless phone) If not, then how?

I have tried only the android emulator in the android sdk, and waydroid until now. Apps installed into both say that they are running on a rooted device, what is right - having access to their image files I could actually do there what I want. However, I would be more happy to run seamlessly also them. Is there a solution, ideally free but also paid might be fine, where I can execute these apps and they do not know that the phone is "rooted"?

Before we start, just want to make it clear that I am aware how easy it is to brick this device, and have decided to go ahead rooting and installing a custom ROM anyway. My goal currently is to use twrp to install magisk and root the phone, but I cannot get the thing to boot into twrp. In case it matters, I'm running Miui 12.0.8.0 Global with Android 10 (4/01/21 patch) on a Global phone. My device is a 6GB/64GB variant with plenty of storage available. I've grabbed the required twrp image from the link in the XDA developers guide (https://forum.xda-developers.com/t/guide-begonia-unlock-bootloader-flash-twrp-and-root-proper.3995919/) as well as a vbmeta image for a Redmi Note 8 because I couldn't find one for the pro variant. I wouldn't expect that's an issue because they run the same OS, but because mine has a mediatek SOC I won't rule it out; if someone has the right vbmeta for me, it would be appreciated. My procedure is as follows: - Boot phone into fastboot, open minimal fastboot/adb from the guide. - Make sure twrp.img and vbmeta.img are in the fastboot directory - fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img - fastboot erase recovery - fastboot flash recovery twrp.img - Hold power and volume up to try to boot recovery. At this point, as long as I keep holding power+vol up the phone will make it to the "REDMI" splash screen, show me the unlocked bootloader icon, and power off. A few seconds later, it will try again to the same result. This will loop indefinitely until I stop holding volume up, at which point it happily boots into Miui; I've let it loop 5 times to be sure. If I hold just vol up (no power) once the phone turns on, like the guide says, it will pass the splash screen and simply shut off. I've tried multiple twrp and vbmeta images to the same result. The next thing to try was to boot directly to the image. I erased recovery, flashed vbmeta, and ran 'fastboot boot twrp.img." The phone hung on the fastboot screen for about 90 seconds before shutting off, and frustratingly then rebooting into *Miui* like nothing happened. If I try to boot to recovery after successfully booting Miui, it works, but I get the stock Xiaomi recovery, which will not help me root my phone. I'm running out of ideas on how to get this thing into the custom recovery. Still a little suspicious it's an AVB related issue, or some form of anti-rollback protection kicking in. Anyone here got any better ideas?

I have a Vantron Tech Tablet model 5081G with Rockchip 3366H processor. All the settings are locked. My PC doesn't recognize it as a USB device. In recovery mode, the only option is to reboot. Can anyone help me to unlock it?

(UPDATE: The accepted answer has since been patched. 12-16-2021) I have a Gabb Wireless which is an Android that is programmed to be "dumb". By "dumb", I mean it only has core apps such as Settings, Phone, Messaging, etc. I like it because it is not additive to where I can't focus on my school. It has some major drawbacks though. To keep kids from messing up the restrictions, they pretty much bricked the phone. I can't flash, ADB*, install apps**, or unlock the bootloader*** the way other sites say to do. All I want to do is host a web server and customize the OS a bit. I have contacted the distributor and of course, they would not reveal anything. Stars: 1. The original way to allow USB debugging/Developer mode is gone. 2. The store was removed and you can't install raw APKs. 3. When I boot into the Bootloader, the screen is blank with "=> FASTBOOT mode..." at the bottom. Overall, I am disappointed with the extremes which the company took. I have gotten them to admit that the device *is* hackable. Of course, any device is hackable so I did not get much from that. Any ideas?

Is it possible to root a Huawei Mate 20 Lite without losing any data? Any help would be greatly appreciated!

I permanently deleted an app on my Android phone and my question is can I recover it if I root the phone or is there any other way to recover the app?

I've been trying to root my xperia ray device by following the instruction given in this post. It doesn't seem to work properly for me.

I'm dealing with a very lengthy and drawn-out FRP bypass. This Samsung Galaxy A54 (A546V), which is on Android 13, refuses to let me bypass it, and I literally have done everything except for modding the firmware. If I can mod and root the device, I know I can get in and remove the FRP lock within the CM. If anyone can point me in the direction of where I will find a way to root, and/or help me mod the phone firmware. I am pretty sure I have exhausted all of the methods and options available to bypass FRP.
