I installed Magisk app, updated the app and then ran the install Magisk. Magisk prompted to restart the tablet, now I am stuck in a boot loop and do not know what to do next. Do you have any suggestions?
HD 10 (2017): Offline rooting
- Thread starter retyre
- Start date
I had this problem a while back with newer magisk versions. I have not tried lately, so I did not know the problem was still there. I wonder why it has not been addressed by now.
I'll give a link to one of my posts in another thread. You can go into recovery using buttons and restore an older magisk version. Again, I have not been flashing anything on this device in a long time, so I hope it still works.

EDIT: That link may be confusing. It's post 1326 in that thread.

54Update: While this still works, there's an easier method here. Please try that first.
Disclaimer #1: KingoRoot, dr.fone, and most other one-click rooting tools are characterized as malware. Should you use these tools? That decision is yours and yours alone. I do not own any of the tools that follow. All the links are to files that are publicly available.
Disclaimer #2: This is a risky undertaking. If you encounter issues or, worse, end up with a brick, I (or the others here) will try to help you, but the risk is all yours.
Disclaimer #3: This approach is not for everyone. If you lack a half-decent linear combination of (1) troubleshooting skills, (2) patience, (3) reading-comprehension skills, and (4) some love of risk, please stop here.
Disclaimer #4: I have only tried this on the 2017 HD 10. If you try this on another device type and it works, please post in the appropriate forum. If you try this on another device type and it does not work, don't be shocked.
NAQ (Never-Asked Questions):
a. What is "offline" rooting?
-- Rooting your device without needing access to the Internet (i.e., the rooting process requires no Internet connection; not on the phone/tablet, not on the computer).
b . Aren't there a gazillion rooting threads for the 2017 HD 10, each claiming to be easier than its predecessors? Why even bother with this fancy "offline" stuff?
-- All of those rooting threads use tools that require Internet access on the PC. What if those tools stop working because of server issues on their end?
-- More importantly, it's well known that these one-click rooting tools extract and transmit a ton of device-identifying information (e.g., IMEI, Serial Number, ...) that is not central to the rooting process. Why give that up?
For a few weeks now, I have been trying to come up with a rooting process that does not require any Internet access on the computer (we know KingoRoot and dr.fone need Internet access on the computer). I have finally figured out how. As a result, we should be able to root the 2017 HD 10 even if these rooting options cease to exist (assuming Amz updates are blocked at 5.6.0.1).
While Kingo does a good job of hiding its root exploits (i.e., the scripts it fetches from the cloud), the good doctor is a bit more generous (its files are downloaded onto a folder on the disk). I copied everything from that folder after a successful root attempt on my test tablet and examined each file. I was able to tinker with the scripts and binaries after moving them to /data/local/tmp on my tablet, but wasn't able to achieve anything meaningful ... until tonight. Noting the presence of some weirdly-named files in that folder, I did a simple Google search and came up with this hit. Of particular interest is method 2 (ELF). Based on that reading and armed with the files from the folder on the disk, I was able to achieve root without Internet access on my computer. I have done so multiple times, w/ and w/o a fresh sideload of the 5.6.0.0 update .bin. The process succeeds more often than it fails (when it does fail, a reboot and retry usually works), not unlike failures with Kingo or the doctor. It's the same exploit after all.
I am guessing Kingo uses a similar process, but does enough to make its scripts difficult to obtain offline. Access to the doctor's scripts and some clarity on the rooting procedure should help others on this forum make even greater progress.
Update: See my post #10 in this thread for Kingo-related instructions. To do this with Kingo, you would complete steps 4 and 5 in this OP and then move to the steps in post #10.
You will need to download a few files (for which you will, of course, need Internet on your computer):
1. Download the exploits here (it's clear that the exploit that's working for the 2017 HD 10 is Dirty COW: CVE-2016-5195): 20165195.zip and SuperSU_18+.zip and extract to their respective folders.
2. Copy all the files from the SuperSU_18+ folder into the 20165195 folder (overwriting wsroot.sh). Rename 20165195 to something simpler, say c. Inside the c folder, you should have the following binaries and scripts: ddexe, debuggerd, fileWork, install-recovery.sh, Matrix, pidof, start_wssud.sh, su, su_arm64, Superuser.apk, supolicy, toolbox, and wsroot.sh. You can delete Superuser.apk (we will be downloading SuperSU next).
3. Download the SuperSU 2.82 SR5 apk from here (or search for another source). Move it to the c folder.
4. Install the Fire's drivers and ADB+fastboot from here (if you haven't already done so).
You will not need Internet access from this point forward.
You should now have the c folder with 12 files and the SuperSU apk handy. If you lose root for whatever reason (or if you just want to test this out), you do not need KingoRoot or dr.fone. Follow these steps:
5. Do the basics:
-- Fire up your Fire.
-- On your first boot, start the process by clicking on Continue, then click on any of the WiFi choices, click Cancel, choose Not Now, and then Skip. Once the Fire gets to the home screen, pull down the notification bar and enable airplane mode.
-- Become a developer by tapping Serial Number (in Device Options) 7 times, go to Developer Options, and Enable ADB.
-- Go to Security in Settings and enable Apps from Unknown Sources.
-- Connect your Fire to the computer, Allow USB debugging on the tablet, check the popup box to Always allow from this computer (if this does not happen here, it will when you start adb next).
-- Type adb shell in an administrative command prompt. You should enter the tablet as a user.
6. On your computer, copy all the files from the c folder to the Fire's internal storage (/sdcard). Next, go to the command prompt with adb shell and copy the files to /data/local/tmp:
7. Change permissions:Code:cp /sdcard/c/* /data/local/tmp cd /data/local/tmp ls -l
8. This is the ballgame: Run:Code:chmod 755 *
This tells Matrix to look for files in /data/local/tmp, with "2" installing su in /system/xbin ("1" installs su8 in /system/xbin). Wait for the process to complete (it will take a minute or two). If it's successful, you will see something like the following as it completes:Code:./Matrix /data/local/tmp 2
If it does not report success as depicted above (note that the memory address exploited might be different, but the end result has to be a "0" and "Done"), delete everything from /data/local/tmp/, (hard) reboot the tablet, and retry (starting from step 5). Failure is likely if an exploit check takes greater than 30 seconds, in which case the device may have to be manually rebooted.Code:[*] exploited 0x7f83021000=f97cff8c end!!!!!!! <WSRoot><Exploit>0</Exploit></WSRoot> <WSRoot><Done>0</Done></WSRoot>
This is a sample of the entire output that should be generated:
9. Confirm by getting to a root shell:
10. Install SuperSU from /sdcard/c/ (you can just click on Docs on your home screen, go to local storage, then the c directory, and install the apk).Code:su
11. Open SuperSU and update binary as Normal (should be successful).
12. Click to reboot.
13. Set SuperSU to Grant as default access.
14. Delete the two wondershare directories in /data/data-lib/:
15. Not required: Perform other cleanup as needed (look for files in /system/xbin, /system/bin, /data, ... based on install date/time, etc.). Mount /system writable if you're going to be cleaning up items in /system:Code:cd /data/data-lib rm -r com.wondershare.DashRoot rm -r wondershare
Code:su mount -w -o remount /system3"Offline" rooting with Kingo
This method is not as offline as the method in the OP, but here's how you can perform a variant of "offline" rooting with Kingo. I will begin by mentioning that Kingo's files are not easily accessible to the user, so you will have to have these files handy before you begin. Sadly, these files can only be obtained while Kingo is doing online rooting. Most (but not all, from what I have seen thus far) of these files are in your AppData\Local\Kingosoft\Kingo Root\files folder, but with different names.
I figured out the actual file names by matching the file sizes in the \files folder on my PC with the files created by Kingo in /data/local/tmp on the tablet while the online Kingo rooting process is _ongoing_ (ls -al). As I mentioned earlier, not every file in /data/local/tmp is in \files, though (could be in other folders on the PC; I haven't looked yet). Following this post, I also did a hex dump of the traffic over USB, but nearly all of it was Kingo transferring its files to /data/local/tmp..
Why does this have to be done while the rooting is in progress? Because Kingo cleans up the /data/local/tmp directory after the rooting is complete. In other words, you will have to copy the files from /data/local/tmp to /sdcard before the rooting completes. If you can do that, these are the files you will obtain: KingoUser.apk, busybox, ddexe, debuggerd, kingo, kingo_1b90d7d01 (likely a copy of KingoUser.apk), kingorootname, mkdevsh, su, suarm64, supolicy, suv7, install-recovery.sh, and libsupol.so (emphasis added to denote the required files). Some information is here as well.
So, what's the best way to obtain these files at this point? Sadly, by rooting (again) with Kingo. (Since these files are not publicly available, I do not think it's right for me to upload them somewhere.) If you can get a hold of these files and save them off the tablet, your future Kingo rooting can be completely offline ... and _mucho_ simpler than the procedure currently in the OP.
Here's what you would do with the aforementioned files:
-- Do steps 4 and 5 in the OP.
-- Download the SuperSU 2.79 apk from here and copy it to /sdcard.
-- Copy all the files Kingo files to a folder on /sdcard (say, k).
-- Copy everything from /sdcard/k to /data/local/tmp:
-- Change permissions to execute:Code:cp /sdcard/k/* /data/local/tmp/ cd /data/local/tmp ls -l
-- This is the actual rooting command:Code:chmod 755 *
This should be done in less than a minute, after which you will be back at the shell prompt.Code:./kingo
-- Test root:
-- Mount /system writable to check:Code:su
-- Install SuperSU 2.79 to get around the "su binary occupied" issue with later SuperSU versions. You should see installation failed (as usual), but things should be fine after the reboot.Code:mount -w -o remount /system
-- Set default access to Grant in SuperSU's settings.
I have tested this multiple times. Works every time. Like I said, much easier than the method currently in the OP, but with the added challenge of obtaining non-public rooting files.
How does Kingo root, you ask? The mkdevsh file in /data/local/tmp (it's not on the computer as far as I can tell) is the only script I could find. At this time, I do not know the exploit being used here; it appears to be significantly more efficient than the doctor's remedy, that's for sure. Anyone interested in reversing the "kingo" binary?2What exploit did you use?
Tried the manual and Kingo method on 5.6.2.0, but still no root access for me
I used the manual/offline method mentioned in post #1 (not the Kingo/step 10 one).
I did have to reboot my device 1 or 2 times before it would apply (making sure to delete the files in /data/local/tmp & then copy them back)
I have Nova Launcher & Google services all running on my 1st tablet now. I'm going to try this again on my 2nd tablet, hopefully tonight.2Just to let everyone know, this method works on FireOS 5.6.2.0, build date: July 6th, 2018, 2:06PM.
I recently purchased the 2-pack of Fire HD 10 Kids Edition Tablet (http://a.co/fUbZ7bg) for my 2 kids & was able to root using this method after accidentally allowing the OTA.
