I was researching on methods to try and recover my data and I learned something interesting, :  This does not exactly answer the original question, but since I managed to brick my bootloader in the meantime, this is what I ended up doing, and it might be useful for someone else in the future: Allwinner SOCs have a built in Boot ROM, and it supports various modes, so these devices are virtually unbrickable. In particular, it supports a so called FEL mode () which can be used to boot the device over USB. I nice open-source tool has been written that can communicate with the device in this special mode (). Using this, you can boot your own bootloader. (And with that, you can boot your own kernel, etc.) The linux-sunxi.org website has very  detailed instructions regarding Allwinner SoC devices, so I recommend that you check out their other articles as well.  I found this quite interesting and so my noggin started to think: could this potentially apply to Snapdragon COCs? Could they potentially contain a built-in Boot ROM? It would be logically possible considering that if perhaps someone completely ruined important partitions, to the point the boot-loader doesn't even load, and it's completely bricked, that Motorola can fix it. I'm pretty sure I recall talking to a Moto Rep a long time ago and they said that it is possible to fix a phone that you messed up all the way up to the bootloader. I would assume 'Yes' they do. So, is it possible?

When running Linux i am able to use SP flash tool to do a readback from my mediatek device and do a full backup of the rom images while the device is in preloader mode, without the use of any additional USB drivers. Yet this is not possible with Google Pixel. Is this perhaps due to Mediatek going out of their way and adding support for their devices during the development of the mainline linux kernel and Google dont?

How do I access the recovery mode in Ubuntu 18.04? I don't see any form of grub bootloader when the system boots - it just goes straight into the OS.

I rooted my Dream/G1 last night and finally gave up on modding it (not for good mind you, but for the moment) and opted instead to just restore it to factory settings via Settings &gt; SD card &amp; phone storage &gt; Factory data reset, which did solve all the problems I was having with multitasking (and not being able to answer it, etc.)  Curiously, I still seem to have root on the phone, despite having reset it. I'd love to understand how that is possible! Superuser Permissions is the only non-stock app still on the phone, and I'm still able to use su to gain root privileges from adb shell. Is this because BusyBox installs to my SD Card?  My phone works just fine, so this is hardly critical, but the whole exercise was/is about knowing my phone better and this is most def. a mystery. Thanks!

I had a Mid-2012 MacBook Pro that recently stopped booting. I narrowed this down based on troubleshooting of the boot device to likely the SATA/hard drive connector/cable no longer working for whatever reason.  I have decided to sell the system. I'd like to know if I remove the hard drive (or in this case, an after-market SSD I've installed) from the system, will there be any other data (i.e. iCloud data) stored on the system on any other chip that I can reset in any way? I plan to reset the SMC/NVRAM before I sell the system off of to someone else.  Additionally, if I remove the hard drive, is the system still associated to iCloud (specifically Find My Mac) or any other service? If so, how do I disassociate it? The system will no longer boot even if I put in my boot device.  Thanks!

I tried to install Android's ROM and got ERROR 7, then I wiped out cache, data, internal storage, where was twrp.apk installed. After that I cant get into boot menu (with Install, Wipe... buttons). Then I copied twrp to the phone: sudo fastboot flash recovery &lt;twrp.img&gt; Tried versions 3.2.1-0 and 3.4.0-0, because I heard for certain phone (I have Xiaomi Mi4) it's necessary to use proper version, though I don't know which. What's going on now: I can successfully can get to the nice splash screen using Volume Down + Power, then on my PC I give sudo fastboot reboot command and press Volume Up + Power and here is the problem: It has no effect, it just keeps rebooting (I see only Xiaomi's logo).

So, yesterday my phone took a serious tumble.  It is now essentially useless, as the screen either fails to turn on, or when it does, there is nothing useful to see (just lines of primary colors, mostly).  I believe (from the fact that it still chirps at me when emails come in, etc), that the phone is still functional, otherwise.  I would like to perform a full system dump, so that I can get off any files from the phone (a TMobile SGS2 (hercules) running slimrom 4.3 build 1).  The sdcard probably isn't important, as I can just pull it, but the phone's own internal storage I should like to get a copy of.  When I plug the phone into a usb port, it 'mounts' the usb via MTP, and I can see all the files.  Unfortunately, when I do a select all | copy | paste operation, the paste op dies before transferring all files.  I've tried a couple other ADB shell operations, in hope of flipping regular USB mounting on, but nothing has worked.  Any ideas how I can get a full dump of my poor phone's contents?  Edit  Currently running a adb pull /sdcard/ ... Its copying files presently, but its too early to tell if its going to get evertying I'm expecting.  Edit #2  looks like its going to work...its taking a rather long time, but it appears to be grabbing everything I was expecting it to.

Greeting's, to clarify; my question is not creating a Live USB drive or a persistence partition but creating a USB with GRUB bootloader (or other) and Kali which can be used on any machine. This is similar to running other linux OS directly from USB. I am currently running Ubuntu from a pen drive. I installed the OS (Ubuntu) and the bootloader on the pen drive and I can boot off it anywhere. Here is a video explaining the same (video is not by me: )  Since, Kali's installer doesn't give option to select which drive to write the booloader to and directly writes on the HDD (sda1). This means even if I partition and install Kali on a pen drive since the bootloader will be installed on the machines fixed primary drive, the USB drive will fail to boot on a different device.  I have two questions:   Anyone has any idea how to write bootloader to a USB drive and what parameters should be given so that it boots with Kali installed on it. I am using graphic install mode for installing Kali on the USB drive, however there is no option for the install to be encrypted (Full disk encryption or at least /home folder to be encrypted). Does anyone know how can I install Kali with full disk / home folder encryption? Or enable is post install?   Thank You!

For an un-rooted device, almost all articles/forum posts I've read say that in order to flash a custom ROM you first need to flash (or boot) a custom recovery image like TWRP.   I'm not sure I understand why. If the bootloader is unlocked shouldn't it be possible to manually flash images that make up the custom ROM to the required partitions with fastboot flash &lt;partition&gt; [ &lt;xxxx.img&gt; ], and leave the stock recovery untouched.  I realize that this may be difficult and that there is no benefit in doing it this way, but I'm curious to know whether or not it is possible, and if not, why?

I want to learn how to root a android phone manually, I mean without any apps like KingRoot, dr.fone etc. I did not found any guides or information about it.  (Background Information: I want to root a BlackBerry KeyOne, even if you say it does not work i want to learn and try it anyway)  Can you please help me?

My phone started rebooting all by itself all the time after I did 2 things with it. Installed Snapdragon BatteryGuru and put it on learning mode (for an estimated 3 days I guess) so that I could start saving battery by the app learning my behavior, and cleaned RAM with CleanMaster. These were the only changes I've done, I don't remember which was first but soon my phone started rebooting whether I was handling it or not at random intervals.  I've also noticed the phone was hot all the time, the Note 3 runs into some hot period with some frequency but not with that frequency. I've uninstalled both apps and it didn't work, wiped cache and it didn't work. The phone was still rebooting even on safe mode. After I wiped Dalvik with the help of TWRP, I thought the problem went away but when I hit the power button to turn the screen off, the phone rebooted and it will now always reboot when the screen turns off, even if it's just from the phone being inactive. It doesn't boot-loops, it just reboots, then after a random time, can be seconds, can be half an hour, it will reboot again. Note 3 SM-N9003 VJUBMI6.

The screen of my phone is physically broken, so it doesn't display anything, but the touch aspect does seem to be working, as I can unlock my phone, and get haptic feedback.  Before I go to get it replaced, I'd like to back up some personal data from the built-in memory to the SD card. I'm fairly certain that if I can get adb to recognize the device, then I can use  to see where I am touching the screen and do what I need to do. Problem is, when I plug it in, it's not recognized, while my emulator is.  I suspect that I might not have USB debugging enabled, which I think is necessary for adb to work. If this is the case, can someone give me screenshots of their Droid X (running 2.3.X) going from the home screen, through all the menus, to activating debug mode? Hopefully I can do it by dead reckoning and adb from there.  Edit: I haven't changed anything about the ROM or launcher; it's all stock.

Can anyone recommend a good way to backup Android devices? Ideally I would like to do this wirelessly and, not only backup my data, but also my user settings. Is it possible to backup an image of an Android device - so that one doesn't even need to reinstall apps? It would be particularly useful to hear from users that have restored backups, as to how easy, and complete, their processes were. Thanks

I am trying to root my Lenovo K8 Plus after unlocking bootloader. I try to install TWRP and somehow the TWRP recovery doesn't open and the phone is struck in the bootloop. I then fastboot the device and connect to PC and open minimal fastboot cmd. The phone wasn't listed in adb device, but listed in fastboot devices. I think usb debugging is not turned on because the system doesn't restart (maybe there is no ROM). What should I do?

So I have an old unlocked phone and I'd like to load up my own OS.  I've seen some mods out there.  CyanogenMod seems to be the most popular.  However, I was curious if I could just install a pure untouched version of the OS -- as distributed by Google. I seem to remember being able to download a clean compiled version of the Android OS.    Does Google distribute any binaries like this, and if not, is there someone out there that does?    Additionally, is this even worth trying?  These days is it necessary for Android to be packaged with special drivers and such for all of the different hardware out there?

I flashed CWM using Rom Manager. Does this mean that my Galaxy S4 bootloader is unlocked?  I'm using Samsung Galaxy S4 (SGH-I337M) (Canadian Telus)

What is the difference between:   Unlocking the bootloader (prerequisite for doing many, though not all, other things below) Rooting Jailbreaking ROM NAND and Nandroid Operating System Mod (e.g. CyanogenMod) Recovery (ClockworkMod, Amon Ra) Custom Kernel (e.g. LeshaK's kernel) Firmware Driver Over The Air (OTA) update Fastboot SIM unlocking Flashing SPL (Second Program Loader)   (any other often-confused terms that I've missed?)

My YU YUPHORIA got bricked while I was working with it. I want to install custom ROM into it for that I am installing custom recovery and boot file but the file that is found on Internet was not working and that's why I am stuck with company logo. I can't go into recovery mod, neither it boot, and USB debugging mode is turned off. I tried to install fresh ROM from fastboot but after installing every driver properly command prompt is showing "waiting for the device". Please sugest some way to get rid of this problem.
