Mediapad m3 missing stock calculator (Bootloader unlock question) - Huawei Mediapad M3 Questions & Answers

I am trying to unlock the bootloader of a US WIFI BTV-W09C128 Mediapad m3 that was previously upgraded to B352.
After the upgrade the tablet no longer has a calculator to get it into manufacture mode.
The google calculator from the playstore will not allow a ( character to be typed in portrait or landscape mode.
I have looked in all the usual places for the native huawei calculator apk with no luck.
Can someone point me in the right direction?

Anyone got any thoughts here?

Has anyone been able to resolve a similar issue?

I haven't resolved your specific issue but I did locate what appears to be the Huawei Calculator App APK on the website here (can't include full address):
android-apk.org/com.android.calculator2/46628588-android-calculator2/

Root Activity Launcher on github. If you don't have root access you can install and then grant app permissions through adb I believe. I've used it but I had the bootloader code saved so only used it to get to project menu after root.

Granting it all permissions when installing via adb (adb install -g) did not work. I see the calculator security function inside of activity launcher but it will not run and returns the message "Root Unavailable".
I have tried every calculator app I could find that claims to be from huawei with no luck. I have a hard time believing that the app is not out there somewhere. At this point I am hoping someone will read this and post their version somewhere.

I was referring to the project menu function within activity launcher. Calculator is only needed to get project menu. If you can get permissions set you can skip calculator and go straight to project menu from activity launcher.

if bootloader unlocked will have a warning when boot

I am the OP and am revisiting this after some time.
I have not been able to get to the project menu using any tool like activity launcher. It presents an error that root is not available/denied.
It seems the only way is with the stock calculator app which was lost over the years. Can someone with a working mediapad m3 post the apk for the original app?

WOO! I managed to get the tablet up and running again. (After all this time!)
Note: I have a US wifi BTV-W09.
Here is what I did at a very high level.
1. Flashed BTV-W09C128B005CUSTC128D001 using the dload sdcard method
2. used dcunlocker to get the bootloader code (money well spent)
3. used multi-tool 8 to unlock bootloader
4. flashed TWRP for EMUI4
5. flashed BTV-W09C128B350 using TWRP
6. upgraded to the TWRP for EMU5
7. flashed the TWRP version listed in the first few posts of the Lineage 15.1 thread
8. flashed lineage 15.1 using the guides from that thread
9. Happy!
I not sure why there are different TWRP versions for each EMUI version but it did not work without this step. Tablet would not boot. I wasted a lot of time thinking I could shortcut this step. Nope. Flash the right TWRP along the way and save time.

nvm

[How To] Downgrade to 4.5.3 so you can root device

Step by step instructional video
Help setting up adb for windows: https://www.youtube.com/watch?v=CyJlmTtLsIg
If you are already running Fire OS 4.5.3 and below, all you need to do is follow this video to root: https://youtu.be/KcQ30qcImJc
Steps:
1. Install the Fire OS 5.0 developer preview. EDIT: Do not do this. If you already have a lollypop ROM installed, use that instead of installing dev preview (You could cause a brick)
2. Enable ADB on your device and set up ADB on your computer
3. Download 4.5.3 firmware: https://kindle-fire-updates.s3.amazonaws.com/update-kindle-20.4.5.3_user_453011120.bin (Mirror coming soon. This download works for the Fire HD7 and HD6)
4. connect device to computer and run "adb reboot recovery"
5. use volume keys and power button to navigate to "Apply update from ADB"
6. from computer type "adb sideload update-kindle-20.4.5.3_user_453011120.bin"
7. from tablet select "wipe data/factory reset"
8. from tablet select "reboot system"
9. Complete setup (do not connect to a wifi network yet)
10. Download KingRoot: http://www.kingroot.net/
11. Download JmzFireHDTool: http://forum.xda-developers.com/fir...ool-jmz-fire-hd-7-tool-gapps-disable-t3113655
12. install both apps. "adb install KingRoot-4.1.0.249-release-nolog-201505211812_105001.apk" and "adb install JmzFireHDTool_v4.apk"
13. Temporarily disable otaverify via adb "adb shell pm block com.amazon.otaverifier" (spelled wrong in video)
14. Connect to wifi so that KingRoot can work
15. Open KingRoot on your device
16. press "try to root"
17. re-enable otaverifier "adb shell pm unblock com.amazon.otaverifier" (spelled wrong in video)
18. Open JMZ Fire Tools and press "Disable OTA's"
Note: If you ever need to upgrade back to lollypop, you should follow these steps so you do not brick device: http://forum.xda-developers.com/fire-hd/general/tools-fire-hd-67-rooting-gapps-t3371242/page4
Awesome find !!! Here is a direct link to the 5.2.0 update file:
http://forum.xda-developers.com/fire-hd/general/lolipop-ota-capture-t3141810
After the downgrade, install TWRP, and upgrade to 4.5.4 but this time with root and fully working GAPPS:
http://forum.xda-developers.com/fire-hd/general/root-v2-0-fireos-4-5-4-gapps-t3150613
http://forum.xda-developers.com/fire-hd/general/how-to-upgrade-to-4-5-4-twrp-root-t3141648
This way one goes directly to SuperSu, and a clean device with no traces of KingRoot.

The tricky part is that the unlocked bootloader still needs a signed kernel. Which is pretty constraining. It'd be interesting to replace the boot preloader, but the risks are high.
Upon boot (if connected to PC), the system flashes MT65xx pre-loader. Which seems to indicate that one could start looking into programs such as "Smart Phone Flash Tool" and "MTK Droid Tools" for MTK chipsets.
Another hope is that the 5.0 version would be sufficiently buggy, such that the bootloader can be made to boot unsigned kernels.

Btw, any chance you could post the direct link to 5.0 preview (for non-developers), since it's probably behind some registration page or something ...
i just signed in with my amazon account, you will need to unroot your fire and reset it as 5.0 is a OTA.

I wish I could find that bin file link... I looked for it but could not find a link to the actual bin file.. If ota's download to the sdcard then It could still be accessed but I don't know where it downloads to. If it downloads to the data dir of the app it would be inaccesable since you need to be on the latest update in order to download the 5.0 version and on the latest version we have no root which means no access to data dir

i have tried but i cant figure it out
It worked perfectly. Thanks
Despite really wanting root and the possibility of using my already paid for apps from the Play store, I really like the lollipop version of fire os. I do think it's a bit ridiculous they haven't retained the old kindle skin because it's exactly how every real android tablet looks but at this point they should be forced by law to let people use the Play store as they wish. Sort of like how Verizon was once forced to allow tethering without a subscription.

does adb devices list your device. Maybe try re-downloading the update in case of corruption
Sent from my LG-V480 using Tapatalk
Perfect timing! Lost root last week and hoped for a way to get back. You the man
I wonder if there is a way to stop the update once it's downloaded, in order to grab the 5.0 update bin from /cache.
This would help to re-pack the update in a way that does not re-write key partitions, then one can have TWRP and root on 5.0
It does sound like 5.0 is a nice update, since it provides stock Android. That's what custom ROMs are usually for, but Amazon will give it away !

I was wondering the same. Seems like you could rename the otaverifier apk back to (plain) .apk and get the download but by keeping com...otaverifier blocked it wouldn't install. I'm just not sure these developer updates are handled like any other.

Root Xperia Z2 Tablet (All Models/Regions) on 5.1.1 build 23.4.B.0.319 in 3 Steps

Hello everyone,
I've noticed that there hasn't been any threads about rooting the Xperia Z2 Tablet on lollipop. Most threads have discussed how to root the device on 4.4.4 and to create an update image to maintain your root whilst updating to 5.0+.
I've scoured the interwebs and found nothing so I'll make it easy for those whom don't know how to achieve root or don't want to do much work without creating images and such.
First off I'm not responsible for any inconvenience that may come with rooting your device and losing your warranty. I can and will be willing to help out in restoring or answering questions that you may have.
This method uses Kingroot... For those who have a problem with kingroot, it is only used to achieve root and this guide will also be showing you how to remove kingroot and install Supersu with ease. Using the link below download the necessary files: Kingroot V4, Supersume, XZDualRecovery 2.8.26. Place all these files on the root of your devices internal storage/SD card excluding Xdualrecovery as that needs a PC. (If you want to Xposed working I will also supply the files needed for that as well). https://www.mediafire.com/download/wrsajbgw2jr6czt
*Make sure you have unknown sources enabled under Settings>Security>Device administrators as well as Developer Options available and USB debugging enabled. (To enable Developer Options go to Settings>About Tablet>Build Number and click it 10 times).
1. Install NewKingroot.apk and run the application. It will notify you that a root method was found and to try it. It may take up to 2 minutes to achieve root. (If all you wanted was root and are content with kinguser then you're done! :good: if you want Supersu and/or a custom recovery then continue on to step 2!
2. Connect your Tablet to your PC via microUSB. On your PC open and extract the contents of TabZ-lockeddualrecovery2.8.26-RELEASE.combined.zip to your desktop. Now double click install.bat a screen will pop up providing you with options to install xdualrecovery. Choose option 2. Installation on ROM rooted with SuperUser by pressing 2 and enter. The script will run its course and tell you to grant permission on your tablet. Open up your tablet and a kinguser prompt will show asking you to grant or deny permission to ADB (Grant it!!!) afterwards your tablet will reboot on it's own to TWRP. (I advise you to either make a backup of the tablet now or after you install Supersu as insurance in case of any mishaps). Click reboot System.
3.Install Supersume, open the application and run it. It will of course ask to grant it permission (Grant it!!!) it will check the environment (making sure that there isn't any Pokemon nearby that you don't need... Sorry Pokemon Go reference) and it will begin removing kingroot and install Supersu. If you didn't have Supersu installed already great! It'll open up Supersu automatically. Supersu may ask you to update binaries (DO NOT click TWRP as it will reboot and you have to start the process over from step one!!! :crying: Just click Normal and once it says successful you're done! :victory: The next step is optional if you Want Xposed.
*Optional 4. Install XposedInstaller_3.0_alpha4.apk. Open your app drawer and open NDR Utils. It will ask for permission (Grant it!!!) now here you may choose your preferred recovery... Philz Touch Recovery,TWRP or Clockwork Mod Recovery. Click Reboot to Primary Recovery (fourth option) once it's rebooted you want to click install>SD>xposed-v85.1-sdk22-arm-by-romracer-20160620.zip and swipe to install. You should get a success when it's finished. Now simply reboot and your apps will be upgrading. Congratulations you now have root with SuperSU and xposed! :victory:
**if you wish to uninstall Xposed simply reboot to recovery and click install>SD>xposed-uninstaller-20151218-arm.zip uninstall the application once it's rebooted and you're good to go!
***if you have a problem with Supersume not working, reinstall Newkingroot.apk and run it again to get root. Then run supersume again (Grant permission!!!) and let it run its magic.
If anyone has issues, has questions or needs help PM and I will do my best to help and answer all your questions. Please don't be discouraged because I'm new here! I will be soon adding a link to a video tutorial on how all these steps can be done!

All there is:

I downloaded the most recent kingroot, which worked on my Verizon sgp561, and then I used your superuser file to change over to su. Seems to work just fine.. I'm on 5.1.1.
I tried the most recent kingroot and it fails.

You can get an account with 4 credits for free via DC-Unlocks facebook page, you need 20 friends though. If you don't have facebook then you can get it for 1 usd from their android app.
The purchase is In-app and uses googles payment system so you can use the spare change from opinion rewards too.

Did you check your USB notification to ensure that it was not used for charging only? Before and after the Manufacture Mode, tap Files in the USB notification, and then select in DC-Unlocker:
Huawei Phones and Auto Select
Also, I had made both $0.99 purchases within the DC-Unlocker Android app which gave me a User and Password in an email that I was able to input into the Server section of the Windows DC-Unlocker app under Unlock which may have helped.
Once the device is found in the lower left, choose Read Bootloader Code and DO NOT select Unlock in the upper right. Paste the Bootloader Code at the end of your "fastboot oem unlock xxxxxxxxxxxxxxx"

You can use the twrp for L09 and flash SuperSU 2.76 after unlocking bootloader. It works. I just had issues trying to backup a ROM.

Installing OTA on rooted Yoga Book

Hello,
I am new to rooting. Several months back I rooted my yoga book using magisk. Root was great except that I couldn't install the Nougat update. And because I didn't think I needed it, I did not make a backup of the stock ROM.
I have tried to unroot the device using the magisk uninstaller. The OTA update still failed to install.
What path should I take to unroot my tablet so it can accept updates?
Thank you very much for any help.
I can confirm that re-flashing an older stock version is possible and restores the ability to install OTAs if you don't have a backup at hand.

OT: was root worth the trip? What special things did you do with root?

Great! I had looked at that post but was unsure what action to take. I downloaded the YB1-X90F_USR_S000196_1611040312_WW06_BP_ROW-flashfiles.zip from the link you posted. Should I follow MarkAllen's instructions in the previous reply to unzip the folder and used fastboot commands to flash the ROM?

For me it was not worth the trip.
I rooted to be able to uninstall NoteSaver because it had an incredibly frustrating glitch when switching to handwriting mode. Several OTA updates did not fix the issue, so I felt great fixing it myself. I didn't use root for anything else. Overall, the time spent troubleshooting and researching was too much. I use the Yoga Book at university to take notes and it was very hard to find time to try to unroot the tablet and get Nougat. I never bricked the device but I spend many hours resetting it.
If I used root to do something more interesting and had more time to play around, sure it might be worth it.

You probably might want to lock the bootloader at the end before you execute the continue command.
Code:
fastboot flashing lock
And it might happen that you face an error while flashing that oemvars bootloader_policy-oemvars.txt. I couldn't find out why that happened and ignoring it seems to be harmless.
As soon as the system started you need to skip the whole first setup and to restore the country code as explained by MarkAllen. Otherwise you might need to re-start from the beginning after installing an OTA.
General info for people that didn't root their yoga book and just want to re-flash the stock system: You'll need the info from this thread since chances are high that you face problems with the usb drivers.

for getting rid of that window adb could have done the trick.
since there is no better rom around, I guess rooting is waste of time - for this device

Thank you very much! Could you just give me better instructions on how to restore the country code? These are the instructions MarkAllen linked to:
you need to input country code to enable keyboard. There are several steps as below :
a) Open ‘’contacts’’ app, create a new local contact ” test”
b) Click search button at contact
c) Input ####6020# code into search bar
d) Browser the country code list, then chose country code you want to use, such as US
e) Then DUT will reboot
How to I skip the whole first setup to get to the contacts app?
Those are exactly the steps you need to follow. It might take some seconds till the new window with the list of all available country codes shows up.
Just use the skip button on the bottom-right of the screen during the setup.

Thank you! The first OTA update installed without a hitch and hopefully it's smooth sailing from here.
I appreciate the excellent technical support!

Beginner Tutorial - Unlock Bootloader + TWRP + Root

Hi everyone, I just want to share this tutorial for someone like me (NEWBIE, NOOB, BEGINNER, ZERO KNOWLEDGE).
ALL CREDITS TO THE RIGHTFUL OWNER.
PRE-REQUISITES
- Laptop
- Applications, .img files (https://mega.nz/file/igphSCTD#OybJo9t1zwvJ0bdbAcN2BCqxWXAfHdhk3JFB4_5xkVc)
- Your Nubia Phone
ENSURE THAT:
- You installed the application and driver (Minimal ADB and Fastboot & the driver from your Nubia phone).
- You updated your OS in the latest version.
- You UNLOCK the developer option (setting>>about phone>>tap 7x the build number) and you switch ON the OEM unlocking & USB Debugging.
- You approved the RSA request in your RM5G
NUBIA RED MAGIC 5G UNLOCK BOOTLOADER
1. Connect your Nubia in laptop, in your laptop, open Minimal ADB and Fastboot and type the following:
a. adb reboot bootloader
b. fastboot oem nubia_unlock NUBIA_NX659J
c. fastboot flash recovery recovery-TWRP-3.4.1B-0324-NUBIA_REDMAGIC_5G-CN-wzsx150.img
d. fastboot flash vbmeta vbmeta_BL_skip.img
e. fastboot flash modem NON-HLOS.bin
f. fastboot flash parameter parameter.img
2. Go to your RM5G, select reboot to recovery
3. It will reboot in TWRP twice, in the 2nd reboot it will stay in TWRP, change the language to English and select the keep read only.
4. Go to WIPE option, then select FORMAT DATA, type yes
5. Press home button, then go to REBOOT, select REBOOT to RECOVERY
NUBIA RED MAGIC 5G ROOTING PROCEDURE
6. Go to ADVANCED, below there are list, select INSTALL ROOT.
7. Reboot your RM5G.
At first, my RM5G restart twice, I was afraid that it was bootloop, the 3rd boots, it booted up and its rooted already.
Also, when I first registered my Finger Print, it’s malfunctioning, so I just deleted the OLD FP , register NEW FP and it works like a charm.
Now, I managed to flash the wonderful kernel of @mslezak.

Great job bro !
Note for those that don't know how to enable developer options - go to settings, about phone, click build number 7x. It should take you right to the Developer Options menu. Nice clear concise guide by the way! Glad someone wrote a simpler one than the one I wrote initially, only so many hours in the day.

Thanks for mentioning the dev. option. All credit to all of you guys who made this possible.
I've been trying for days to download the MEGA zip, but no matter what I do it always stays on 0% and gives me an error. I tried on different browsers, on different computers, and using the desktop app, I even tried with the mobile app with no luck. Could someone please share a mirror or another link, please?
Nevermind, I was finally able to download the file, my solution was to use chrome instead of firefox and close every window except the mega one... I left it like that for a couple of hours and it finally downloaded it.
Possibly a stupid question, but are there any downsides to this other than the risk of bricking?

Its a normal troubleshooting, if its not working to other browser, try another one, great to hear that you managed, happy rooting.

Thanks but this isn't what I meant, I was thinking more so of apps not working due to root detection. Banking apps or others?

You can hide the Magisk (setting/select the apps/then hide magisk) so it will not detect that you are rooted.

Hi,
2 questions. First of all, does this method work for all of the 5G phones? As in the European version etc. And second of all, will the phone brick if you update it via OTA, or do we need to do this method every time?

Hi, see attached. You have to rename the Magisk after selecting in pic. # 1.
You can find the FP calibration procedure here in XDA.
Ty ?
Hi Guys, first of all thanks for awesome tutorial. Got it rooted and enjoying the perks. However, some issues do exist. 1. The phone has detected a new update v4.09. Will the root be deactivated if I update the system? Second question, my banking app is detecting the root and does not want to start. I did set magisk manager to hide it from the app and restarted the phone even, but no luck the app still sees the root. Any solution for it? Thanks all
hello I would like to know how to put it back original? bootloader, Root ... thank you

1. If you updated your RM5G before rooting, its bug, ignore it.
2. Mine is working as i showed in the photo above (ANB)
