[Q] Rooting the 3G Xoom (Stock 3.2) with CWM - error 0x120000

Hi folks,
atm I feel like a complete newb because I cant manage to root my xoom according to http://forum.xda-developers.com/showthread.php?t=1074979 with fastboot. (Can't flash through cwm since the device is stock 3.2)
What I have:
Motorola Xoom EU 3G (MZ601)
Android Version 3.2
Kernel 2.6.36.3
Firmware GAS_EMEA_USAEVRSTUTMDE_P016
What doesn't work:
As soon as I try to flash recovery my almighty command line says:
Code:
>fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
sending 'recovery' (3998 KB)...
OKAY [ 0.490s]
writing 'recovery'...
FAILED (command write failed (Unknown error))
finished. total time: 1.103s
My xoom shows "Starting Fastboot protocol support" as if nothing happened.
When I try to issue the command again immediatly, the error changes to:
Code:
>fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
sending 'recovery' (3998 KB)...
FAILED (remote: (00120000))
finished. total time: 0.274s
The xoom is showing "Failed to process command error(0x120000)".
Here is what I've done so far, aside from following the post mentioned above including all tipps in that thread.
tried three different cables for connecting the xoom to my PC, including the original one.
tried two different computers with three different OSs (x64 only so far)
tried to flash the image immediatly after the oem unlock without booting into system
tried everey single usb port on every system
tried updating chipset drivers as well as the usb drivers
I don't know what to try next. Could someone please give me a hint what to try next? I'm stuck here.
Thanks in advance & thanks for reading, Jan

Have you tried to check the md5-checksum of the image file?

Hi, indeed, I forgot that. I've checked it and they are matching, so no luck here.
Does someone know if maybe 64bit systems could cause problems? (And what to do aside from buying a new PC ^^)

well, they could but on my 64bit system everything worked out fine. You could try installing a 32 bit OS, as your computer is likely compatible to that. I don't, however, believe that would do any good as it looks like your computer is doing what it should, only your xoom isn't... (to me, it looks like your computer is sending the file just fine but the xoom just doesn't want to flash that file to memory)...

I'm a bit confused because it says "MZ600", but according to the tablet info when android has booted it is a MZ601.
I'm living in germany, where I've also bought the device and it's got a 3g module which i'm actually using.

did you just omit the (bootloader) iswarrantyvoid: yes or did that really not appear? Apart from that, everything looks just like on my device... Thus, I am officially out of ideas... I'd offer to have a look at your device next week as I'll be in your location then but I currently don't see how that would do any good...

yeah, that distracted me at first too, but a friends MZ601 which is neither rooted nor unlocked, says the same, so I think thats fine...

can you flash a the recovery image from Motorola?

Actually, I couldn't.
I didn't even try before. This simple question of yours emerged something like a nerdrage from deep inside.
I looked sternly at my xoom and decided that I won't go down first.
Well, the rest was luck, but since I've tried it multiple times and it worked, here are the steps:
Start slowly with these lines (I know them by heart by now)
Code:
adb reboot bootloader
fastboot flash recovery recovery-solarnz-XXXXXX-XXXX.img
It will fail. Do the last line again, it will show error 0x120000.
Now you have to be quick as soon as you submitted the next line:
Code:
fastboot reboot
Unplug your device from the PC and start hitting the Volume down button immediatly (this means: do not tap and hold, press it multiple times) until the display says fastboot is ready .
Now re-plug the xoom to the PC again and re-do this:
Code:
fastboot flash recovery recovery-solarnz-XXXXXX-XXXX.img
This time, everything goes well.
If, like me, you are coming from stock, don't forget you must not reboot to system again, but directly to recovery and install something like Team EOS ROM.
I have no clue why it worked, but since I was so fascinated that I've tried it three times I guess one could say it's reproducable.
Good night and thanks to llama-power for being inspirational.

I have no idea why the information seems to be wrong, but obviously it can be ignored, at least in my case.
As long as you've got a 3G module, it is not a MZ600, regardless what fastboot is saying.

[GUIDE] How To Root HTC One XL Firmware 5.05.707.1 Android 4.2.2

Welcome to my noob-proof guide on how to root HTC One XL!!!​
EDIT: Guide not available for AT&T Phones (Special thanks to timmaaa)
I WILL NOT TAKE RESPONSIBILITY IF YOUR PHONE IS BRICKED AFTER USING MY GUIDE, USE IT AT YOUR OWN RISK!!!
I will now slowly guide you through the steps to root your One XL
Step 1 : Unlock your Bootloader
Unlock your bootloader through HTCdev.com. Create an account and go to Unlock Bootloader, select All Other Supported Models and follow the instructions. To check if your bootloader is unlocked, enter bootloader mode by holding the Volume Down button while your phone is powering onIf your bootloader is unlocked, it should say *UNLOCKED* at the top right of the screen.
Step 2 : Flash A Custom Recovery
Download a custom recovery (TWRP and CWM are the two main ones)
For TWRP, download version 2.6.3.0 (i'm not sure about CWM, i didnt use it)
Enter bootloader mode and go to fastboot (Volume Up / Down to move around, Power button to select option)
Plug it into your PC/Desktop through USB and it should say "Fastboot USB" highlighted in red on your screen
Go to your Command Prompt (Start > Search Command Prompt)
Type in the following code:
fastboot flash recovery RECOVERYIMG.img
REPLACE RECOVERYIMG TO THE NAME OF YOUR RECOVERY (YOU MAY RENAME IT)
Fastboot will flash the image and give you a success/failure notification.
If it is successful, use the command fastboot erase cache to wipe your cache/dalvik
To check out the new recovery image, go back to Hboot menu by selecting bootloader and clicking the power button,
Use volume down to highlight recovery and press the power button. The phone will now attempt to boot into the new recovery image. You'll see the htc splash screen briefly and then the recovery image.
Step 3 : Rooting
For TWRP click reboot and then click system. It will tell you that your device hasnt yet been rooted and needs to install SuperSU to do so. Swipe to install the SuperSU.apk
For CWM i'm afraid I can't help you with that, sorry im not sure how to install SuperSU using CWM but you can ask around
If you have followed these steps correctly, your device should now have full root access!!! Download the Root Checker app to find out if your device is rooted or not.
If you're satisfied with this guide, don't hesitate to click the thanks button!!!

This guide isn't complete, this will not work for at&t phones. At&t phones cannot unlock via htcdev as the at&t CID is blocked. Maybe you could just update the title to note that this is a guide for non at&t phones.
Also, after flashing the recovery you also need to give the following fastboot command:
Code:
fastboot erase cache
Another thing you might want to put in there is that the user will need to have a working adb/fastboot environment and HTC drivers installed, and instructions on how to do so.
Sent from my Evita

If a person is truly a noob, they will have no idea what fastboot is, and not have a fastboot environment ready to go. This is a huge missing step(s).
Need links to thing, like TWRP and fastboot resources (once added).
Really, I hate to say, this isn't much of a guide in its present form. It basically says "Go to htcdev.com and follow the steps, then install TWRP". If a person can't handle those things, they shouldn't be modding their phone. This guide needs a lot more work, to be really useful.

Agree 100%

That wouldn't be an upgrade (RUU to 3.18), it would be a downgrade as you are presently on 5.05. With S-off, you can just run the 3.18 RUU. But do I'm not sure you have a valid reason for doing so, as I think you may be confused about this. But its not clear, as you haven't given much detail on what you are trying to accomplish or why.
Also, this has little or nothing to do with the topic or this thread, and you really shouldn't have dug up a 3-month old thread in order to post your issue.

thank you, i did it, but now i have a problem with rom Cynogenmod 10.2. wifi doesn't work, i try anything with my router but it is not work pls help me

Need help restoring HTC One S. Or flash a working Rom!?

( Text below is just an explanation to my issues and why I need help! )
Hallo dear XDA forum people I ahve many times read posts and fixes about my cellphone here and managed to unlock, root and install Super SU on my HTC One S. It still has the stock rom, given it's now unlocked and rooted etc. Last weeks I've been having problems with calling out or receiving phone calls. Due to the cellphone hangs every time. So factory reset it to default. The problem persisted somewhat. It now just gets sluggish and I can't hear the other one speaking. Even though the cellphone actually made the connection. So thought about downloading a RUU or flash to another ROM to see if it's cleaner and more stable.
What I done so far!
Before tampering with the cellphone I took backup .img files of my ROM. I even took a manual ''Copy everything on the cellphone to my PC'' in case this would happen. So....
I have installed Universal ADB Drivers, JDK for Java, Android Studio bundle, The HTC One Toolkit - Squabbi - 3.1.2 version. Not that it done any good so far.
The BIG problem is that the cellphone can't mount it's memory card. So I can't put any ROMS, FLASH FILES, .zips or anything on it. I failed at forcing data into the ''data'' folder to.
And when I try to flash a file directly using ''Fastboot'' the device hangs at:
sending 'zip' (632094 KB)...
OKAY [ 27.661s]
writing 'zip'...
FAILED (remote: not allowed)
finished. total time: 27.691s
Other problems when working with the ''ADB commands'' gives me the ''Device not found'' response.
I downloaded the RUU for my device as a .zip as there's no existing .exe version to be found. With no luck flashing it I might say. Due to the constant hanging when the file is ''Sending''.
( This is the RUU I downloaded: OTA_Ville_U_JB_45_S_HTC_Europe_3.16.401.8_1.11.50.05.28_10.27.50.08L_release_301852xf01hejl416oev96.zip )
And for 2 days with applying fix after fix and trial and error I'm coming nowhere! I'm thinking on formatting the whole cellphone and copy my ''manual copy of my cellphone'' into the formatted cellphone drive.
In the bootloader this information can be seen:
*** TAMPERED ***
*** RELOCKED *** (Along the lines of guides this happen. No idea how though
VLE PVT SHIP S-ON RL

My cellphone has: Philz touch 5 CWM Base version 6.0,3,2 on it.
NOW! This is what actually works on my cellphone:
1. I can get into BootLoader on my HTC One S!
2. I can get into Fastboot on my HTC One S!
3. The Fastboot on my HTC One S recognizes as ''Fastboot USB'' on when I plug it into my computer.
4. My computer recognizes the cellphone as a ''removable disk''. And using the command ''Fastboot Devices'' in CMD lets me see the ''SH32HW401164'' number. Using the command ''Fastboot getvar all'' gives me this information:

My plan was to flash this ROM into my phone if the stock one still showed issues: http://forum.xda-developers.com/showthread.php?t=2531065
This being said and again: My HTC One S is NOT flashed with a custom ROM! It has the same ROM it came with, all though, it has been unlocked -> Rooted. And never been S-off. it is still S-On.
Any help with this issues would be appreciated and thanks for this great forum

SOLVED flashed working ROM and fixed SD card mounting error.
After 3 weeks of frustration and trying I finally got my phone booting with a ROM. As I couldn't find any RUU.exe files for my phone and the RUU.zips didn't work either I had to go custom ROMing. I'll explain the whole process with steps I did so that others can read easily
1. Go into Bootloader, choose Fastboot and connect your phone with the USB cable. Open up CMD in your Fastboot/ADB folder by holding SHIFT+Right Click and type: ''Fastboot devices'' without the quotas, to see if your phone appear like SH32HW.... etc. You can also use the command: ''Fastboot getvar all'' to pull a few lines of comparable information.
2. Download the stock recovery file here: http://loadbalancing.modaco.com/download.php?file=ville_recovery_signed.img , place it in the Fastboot/ADB folder and open CMD again, if you haven't already, in the Fastboot/ADB folder and type ''Fastboot flash recovery ville_recovery_signed.img''
Let the file flash and when it's done type ''Fastboot reboot-bootloader''
3. After the short reboot choose Clear Storage. Your phone might try to boot after this. just hold the power button + volume down to restart it into bootloader again. Then choose Factory Reset from bootloader menu. The phone might try to boot again after this but restart it manually into bootloader if it gets stuck.
4. After clearing storage and factory resetting go into Fastboot USB mode again and use CMD in the Fastboot/ADB folder again to flash your custom recovery file. I used TWRP 2.8.7.0.zip. This TWRP recovery is signed for HTC One S S4. The guide for the Viper ROM recommends the TWRP2.6.3.0 for phones with HBoot 2.15, and TWRP2.6.1.0 for Hboot 2.16 phones.
The command for flashing this file is ''Fastboot flash recovery twrp-2.8.7.0-ville.img''
5. After flashing the custom recovery reboot bootloader with the command ''Fastboot reboot-bootloader''. Then after the short reboot go into recovery from bootloader.
6. At this time your SD card should work. Choose to mount USB from the ''Mount'' menu in TWRP. Attach the USB cable if you haven't already. Transfer your ROM.zip file to your SD card with this method.
( I used the Viper ROM found here: http://venomroms.com/htc-one-s/ )
7. After the transfer is complete choose ''install from zip'' in TWRP and choose the ROM.zip of your choice.
( I choose the Viper_One_S_3.2.0.zip file and chose the ''full wipe'' option, removing apps I didn't want etc. )
8. After installation let the phone work it's magic for like 10-15 minutes if necessary. It'll hopefully boot into the new system in time and you can complete the setup
---
The importance is that the stock recovery steps up til I flashed TWRP again fixed the SD card error. There's more fixes you could try if this didn't work and they can be found here: http://forum.xda-developers.com/showthread.php?t=2086156

I told you to flash the stock recovery and make a factory reset from bootloader from the beginning. Glad you've sorted out finally

Yes but it was hard finding a stock recovery. And the recovery that came with the phone did not work. So had to try lot of different ''what was supposed to be stock'' recoveries before I found one that worked Thanks by the way ^^

I didn't have a link for it either. I had to do that only once (messed my sdcard) and I remember someone posted a link from MoDaCo where Paul O'Brian had it uploaded...if I remember right. But that was long time ago and I didn't have the link anymore

Hmm... My SD card actually got un-mountable and messed up after having stock ROM and just choosing to do a factory reset in the bootloader. That is when my problems started! But now after testing just this recovery and clearing storage, factory rest, flash new TWRP in exact that order fixd my issue. If I would factory reset before clearing storage and cache it would do nothing for me. It's weird but now it's ok and works ^^
Should have made a video of me restoring my phone to youtube so others can see to O.O

Please Help with Bricked Xoom?

Hi all,
I've exhausted all my resources in trying to get this tablet to work. It might be hard bricked if that's even possible. Just a little back ground on what happened. The device was running very slow after 3yrs of using wingray (wifi MZ604?) [ROM][4.4.4] OmniROM - Wingray - bigPart. Anyway it's from Verizon and it only has wifi. But as I said, it was running very slow so I figured i'd flash back to stock ROM. The stock ROM flash fine and it was pretty responsive. Then this where everything went to sh!*.. I received an update notification, it updated, rebooted and the tablet is stuck on Dual Core M boot screen. I have tried to restore by flashing OmniROM - Wingray - bigPart and RDS back to stock ROM, both stuck on Dual Core M boot screen.
I spent over 48 man hours reading through the forums on how to unbrick this tablet. Unlocking the botloader and pushing twrp big part and flashing a custom ROM, to using One Click Tool made by XxLordxX to try to get it back to stock and installing Omni ROM. None of which seam to work. It always ends up stuck on Dual Core M boot screen until it runs out of battery charge. There is no way I can get into any type of recovery.
I have access to the following items:
- fastboot
- RDS
I don't have access to the following:
- bootloader
- ADB
- default or custom recovery
If anyone can assist, I would really appreciate it.
Edit: if it helps, this is what i extracted from the device in fastboot
Code:

download twrp img file and use fastboot to upload the recovery? "fastboot flash recovery twrp-3.0.x.x-xxx.img" just gotta find which twrp you want. by the by, I just flashed the files from here and now I am getting a boot screen instead of stuck at bootloader like you ;
https://www.dropbox.com/sh/1fxrnv2ce8fyjyn/AABHGMZcGCYBYqtDSvMMpXC-a?dl=0
Which is from here - give the man props! https://forum.xda-developers.com/motorola-xoom/general/roms-motorola-xoom-t3602655

Unfortunately any twrp recovery I flash with fastboot doesn't allow me into recovery. Without recovery I can't flash those archives. Very annoying. But thanks for the heads up. I guess the main priority is to get a working recovery.

Change the usb cable. I'm not joking, that might be the problem!
If that doesn't work, use RSD lite to flash the original ROM (the SBF file, you will find it on the internet). Make sure to flash the corresponding SBF to your tablet.

Yea I believe you about the USB cable but unfortunately this was a hand me down and the original cable was lost.
I've tried all the SBF files I can get my hands on and it still gets stuck on the M logo screen and I can't get into recovery mode. I can list all the sbf files I've tried. They are still stored on my NAS.

Hello nomadman,
Check a zip from this thread according to your Xoom model version and area:

Unzip the file. And do these commands to boot your rom:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
Use this method to your own risk. I think it should work, but... I suppose it is your only chance to have stock rom again.

Thanks @Manuallama. I will give this a shot since I don't really have a choice. Before I flash I usually fastboot clear those boot, user, and system. We do this when I get home from work. Cheers

installing TWRP and rooting Asus Zenpad 10 (Z300m)

THIS THREAD IS NO LONGER UNDER DEVELOPMENT, FOR FUTURE UPDATES PLEASE HEAD HERE.
Flashing TWRP and Rooting the Asus Zenpad 10 (Z300M)
CREDIT: Diplomatic, JustShaun, and Flukester69 all made this possible. But really if anybody needs an applause, it's Diplomatic. If you wish to thank him you can do so here.
IMPORTANT! READ BEFORE CONTINUING!
Nobody here is responsible if you mess up your tablet! This is your decision and yours alone! Yes, this will void your Warranty! The below is based on the success of our own testing. We suggest reading this multiple times if necessary, before attempting. Ask questions if you are unsure, I'm sure someone will try and help.
Things you'll need:
- Windows computer / possibly Linux if you are savvy enough.
- Z300m with Android 7 (check if there's updates, if so, reboot tablet when done.)
- USB Cable (the one that came with it, or one you are sure works)
- MediaTek VCOM Preloader Drivers (I will explain further below) (Win10 installed drivers work too)
- Z300m Scatter File
- TWRP 3.1.1 image
- SP Flash Tool 5.1532
- SP Flash Tool 5.1548 or later (latest is 5.1720 at the time of this writing)
- Magisk Manager (Beta 13 works)
or
- TWRP 3.1.1 Recoveryasboot
Create a temp folder on your desktop and throw all the above downloads in there.
MTK Driver Install - Pre-Flashing Procedure:
Turn your tablet OFF and plug it in to your computer, Windows should recognize the device and download the drivers. You should be able to manually search through device manager (Turn on Hidden devices might be necessary). When the drivers have been downloaded feel free to unplug the tablet again.
You'll want to make sure the drivers are installed properly. A quick way to test,
Open Device Manager by either searching for it or running 'devmgmt.msc'
Turn on hidden devices.
Expand the 'Ports (COM & LPT) section
If the drivers are installed properly you should see 'MediaTek PreLoader USB VCOM Port (COM*)'
Good enough, if that worked. If not, check your device manager and figure out your driver issue.
Backing Up:
Open the SPFL (latest) dir and open option.ini in any text editor, you'll want to change "[ReadBack] ShowByScatter=false" from false to true and save your changes.
Load into flash_tool.exe.
Change the download-agent from MTK_AllInOne_DA.bin to DA_PL.bin - This is located under the SPFL dir.
Add the Scatter-loading file which should have been downloaded previously.
Head into the Readback tab and you should see 'Preloader, pgpt, proinfo ect...'. Check all of these boxes and click Read Back
Make sure the tablet is turned off and then plug it into your computer. Bar goes red, yellow and then done. Green Checkmark.
It's safe to unplug the USB from the tablet now and you can close the Flash Tool
Flashing TWRP:
It's up to you to backup your tablet. You should, but the tablet technically should reset if anything fails. Another choice that is up to you alone.
Again, Make sure your tablet is powered off and NO USB plugged in. This is basically the same procedure as backing up, except you're using the Download tab instead of Readback.
Extract SP-Flash-Tool-v5.1532.00 and Launch flash_tool.exe.
Change the download-agent from MTK_AllInOne_DA.bin to DA_PL.bin - This is located under the SP-Flash-Tool-v5.1532.00 dir.
Add the Scatter-loading file which should have been downloaded previously.
Look down the list you see Recovery line, click on the right side, point it to the TWRP.img you downloaded. (Make sure this line is only checked.)
Click the Download button and THEN plug in the USB cable to your tablet. Bar goes red, yellow and then done. Green Checkmark.
It's safe to unplug the USB from the tablet now and you can close the Flash Tool
Alternative method that does not require SP Flash Tool, scatter file, etc.
Unlock the bootloader: Download the Asus unlock tool for your tablet here and run it. (It's an APK from ASUS. When done you reboot tablet, you will see a message Your Device Cannot be Trusted..., you're unlocked.)
Download twrp-recoveryasboot-3.1.1-0-z300m.img.
Make sure you have fastboot/adb installed on your PC. Put your tablet in fastboot mode by holding Volume Up and Power, then selecting Fastboot Mode from the menu, and connect to PC.
Run this command to do a tethered boot of TWRP
fastboot boot twrp-recoveryasboot-3.1.1-0-z300m.img​
This will boot but will not install TWRP. You may be able to do whatever you need in this environment. But it is recommended to install TWRP to your flash ROM, and proceed from there.
To flash TWRP from TWRP, go to Install -> Install Image. Select the twrp-3.1.1-0-z300m.img file you downloaded earlier (not the twrp-recoveryasboot*.img file). Select Recovery, then swipe to flash.
Reboot to Recovery
[TWRP first launch]
Now press and hold both the Volume Up and Power button at the same time. Tablet will show a list so let go of the buttons.
Use the Up volume now to select Recovery and press Down volume to select. Tablet should reboot into TWRP. (takes 10-15 seconds)
A dialogue will show in TWRP stating that there is a chance Recovery will be restored (the Asus one) so slide across to keep TWRP.
Mounting /system in read/write mode could be potentially hazardous, this is patched at your own risk.
***NOTE: You will need to boot into the recovery immediately after flashing, failing to do so will result in the Android OS reflashing its stock recovery. If you are concerned about which recovery is installed I would suggest using 'adb reboot recovery' to minimize risk.
[ROOTING]
Put the Magisk flash file on a working micro sdcard and pop it in your device. (this won't get deleted and can be accessed by TWRP)
Don't reboot yet, we need to flash Root (you should have Magisk img/zip on your micro sd inserted in tablet)
Assuming you are familiar with TWRP, Install the Magisk Manager.
When this is done, reboot your tablet to System with TWRP.
We've tried to make this guide as helpful as possible, read this thread and the Z380 thread as there may be new things learned, past experiences of others that could help you.
Enjoy your Rooted Tablet!

Thanks! Any chance of instructions for us using Linux?
Maybe we'll get LineageOS for this soon!

New TWRP Image March 4, 2018
Up to date precompiled kernel from firmware WW-5.3.19
Up to date TWRP/AOSP sources, including TWRP 3.2.1-0
Unified image that may be flashed to recovery or boot partitions, or be used for tethered boot
Guide and downloads on my new TWRP thread
Upgrade Installation
Copy the new image file to your tablet, then use your existing TWRP to Install->Install Image the .img file to Recovery. Then reboot to recovery.
Mandatory step: after trying this release out, you must come back here and post whether it works or not.
(Source code on my Z380M thread.)

Good job ! It's more than anyone else has managed to do so far

In order to navigate through TWRP you will need to attach the OTG cable and mouse to your tablet, it doesn't currently have any touchscreen functionality. Reboot into the system and make sure to patch your OS.

After looking at kernel logs and old source code, it seems like the touchscreen driver is intentionally disabled from working in recovery mode. If we had updated kernel sources, this could be fixed easily.

Try the Linux flavor of SP Flash Tool?

Wow this is quite the process and twrp with no touch screen? Plz post your success to raise confidence of others like me. Last f'ng tablet I ever buy from Asus. Let's also not forget you will be stuck on this release forever afterwards.

You can try the Asus unlock tool to be able to flash with fastboot and not worry about SP Flash Tool. At least one person got it work on the Z380M. And you can always unroot/restore original boot & system images to be able to upgrade the firmware. Also, it's kind of unfair to rate a company poorly for not supporting your hacks, especially since this tablet is basically unbrickable AFAIK.

Restore the original boot image if you only have systemless root. And also the system image if you've modified it.

I'll give it a try at some point man, not sure about the unbrickable part, $hit happens. Do you have a reference for the guy with the 380 that flashed via fastboot? that would be the preferable method for me really.
---------- Post added at 10:20 PM ---------- Previous post was at 10:01 PM ----------
What is Magisk? Is it really needed? If TWRP is installed with the Flashtools can I not just flash SuperSU with TWRP? If you could clarify?
When I tried the command to flash recovery I got the following...
Code:
C:\adb>fastboot flash recovery recovery.img
target reported max download size of 134217728 bytes
sending 'recovery' (13958 KB)...
OKAY [ 0.445s]
writing 'recovery'...
FAILED (remote: download for partition 'recovery' is not allowed
)
finished. total time: 0.452s

What I meant by unbrickable was that you can use SP Flash Tool to talk directly with the SoC. That gives you low-level access to the flash ROM without depending on any software on it. So for example, if your bootloader or partition table is messed up, something that would brick most devices, you can flash those in without needing to get into the bootloader. I'm not 100% sure this is possible, but I'm pretty confident it is.
This is the post where the guy unlocked the bootloader. But I'm not sure he used fastboot to flash. TBH, FlashTool is not that complicated. Most of that stuff in the guide has to do with backing up your flash memory. If you wanna skip that part, that's up to you. You can just go ahead and use Flash Tool 5.1532 with the scatter file and the right download-agent to flash the recovery. BTW, you can follow that thread as well. Whatever applies to the Zenpad Z380M usually applies to the Z300M too.
Magisk is another root manager like SuperSU. SuperSU seems to have compatibility problems with this tablet. (I have not tried either.)

then
Click download at the top and plug in your tablet while it's still off. Assuming all goes well, the 'Download Flash' section at the bottom should be sitting on 100% and you should have a lovely green tick on your screen.

So when I press Download button in flash tool, the tablet needs to be OFF? Like powered off completely? Because nothing happens other than seeing the untrusted device (cuz it's unlocked) and the battery charging display.

Yeah, completely off. Have you installed the Mediatek USB port drivers? Where does it say untrusted device?
So after you unlocked it, have you tried fastboot flash? And you also don't need to use the 5.1532 version. I think the latest one will work too. The 1532 is just the NSA courtesy version.

Installed is whatever Win10 installed. I didn't try other drivers because adb / fastboot appear to work but I can try some other drivers.
Whenever I boot the tablet, it says untrusted device because the bootloader is unlocked. It says, booting in 5 seconds.
I do a fastboot reboot bootloader and I see it says fastboot ready at the bottom of the screen. When I type fastboot devices, it says my device in the list.
I tried fastboot flash recovery recovery.img if that's what you're asking (didn't work, so that's why I went with the software)

So just to be clear, you were getting 'FAILED (remote: download for partition 'recovery' is not allowed)' AFTER you've unlocked the bootloader?
If it's not being detected by SP Flash Tool, then something's wrong with your driver installation. Remember, those Mediatek USB drivers are not the same ones your ADB and/or Fastboot drivers. Check your Device Manger, under Ports, for a device called "MediaTek PreLoader USB VCOM (Android)". You have to check View->Show Hidden Devices to see it when your device is disconnected. You might have to right click and Update Driver Software to fix it.

I got the failed with the fastboot command not the flash tool. I'll try and install the mediatek special drivers you are most likely right that they differ from the sdk provided ones. Reading other threads I understand the flash tool a bit more too. I'll do a bit more work on it and provide feedback. Thanks for your help diplomatic.

No, I know the message is from fastboot... I'm asking if you have tried fastboot flash with your bootloader UNLOCKED. Because that message indicates that your bootloader was locked when you ran it.

Well I ran the bootloader unlock tool I downloaded from Asus and ran it so I assumed it's unlocked. I tried to install drivers (latest I could find) but Windows 10 (64-bit) says I have latest installed. I checked device manager and when my tablet is off and I connect it I see the drivers(3) become active for a few seconds and then they turn off. Seems to me something is not working with this process. If you look below it seems to indicate to me the bootloader is unlocked.
Here is info

LOL! OK. I figured $h.. out... The problem was this...
The device must be OFF and DISCONNECTED and ONLY connected when you hit the download button. The reason is, the driver shuts off if there is no data transferring. Very important detail. I am guessing this is what the issue was and why the flash tool was not working. Now I probably got old crap drivers by forcing them through Windows Troubleshooter to override signature verification. So anyway I tried flashing anyway and it failed. I suspect because I overrided good drivers with old ones. You can see what I got here.
https://ibb.co/mwkHFv

Whoa, that's kind of unexpected that fastboot would not let you flash even though it's unlocked. And the latest SPFT is not letting you download either. It says it's unlocked but it's acting like it's locked. But you're really close....
That S_SECURITY_SECURE... (6045) message is just the Flashtool's version of fastboot not allowed error (locked bootloader). So you still have to use 5.1532 to flash it. That's all.
I will post a signed image of TWRP to see if that will work for you.

OK That worked with the 5.1532 and I booted to recovery and TWRP is there. Woohoo! Thanks for the continued help! I was getting frustrated. Not like the first device I flashed/rooted etc...
Disconnecting of the tablet until after Download button was one, the next the version of SP Flash.. cool. Making progress.
So you say SuperSU don't work... Magick one works though but installs crap, then you could use sysuninstaller to remove the crap...? Think I read that somewhere. Ok I'll read up anyway, kinda curious why SuperSU
wont work or has problems.
Also know that I removed all the MTK (older) drivers using USBDeview and then rebooting my tablet and going through all the modes, fastboot etc.. the drivers eventually all the Windows certified re-installed (the MS ones). So no need to download drivers either I guess.
Edit: this is a 1 time deal apparently. I had twrp installed but as I didn't have supersu 2.82 downloaded I rebooted out of recovery. Next attempt to go to recovery resulted in "Erasing" so I lost all my apps and had to setup my tablet all over again. Oh well, guess I know what to do now. Try again tomorrow.

All right, good job, man! :good: I'm sure our discussion will clarify the process for others...
As for root, someone else should help you out. I have not put root on my tablet. All my hacks and mods are done through TWRP.
I'm still surprised that the unlocked bootloader did not let you flash it.
