How to downgrade to OS 1.5 on Remix Ultra tablet?

My Remix Ultratablet current running 2.0.305 keep random restart everyday.
So I wish to downgrade to OS 1.5
I ask for help form office Jide support , they told me I need to
Q1) Problem # stuck on step #1 already , When I ask where is the Remix Ultratablet driver when I install adb and fastboot ? Offical jide support told me I don't need a driver? How so ?
I can't get the tablet connect ??
Note: 1, I connect the tablet with USB to PC
Note: 2, I turn the USB debugging option on Tablet already.
Note: 3, I Test it on pc adb folder by trying "fastboot devices" only get "Waiting for Device" error
Q2) I also try other method (Power key + Volume up) on tablet which show
"Continue
Fastboot Protocol
Recovery Kernel
Reboot
Poweroff
Forced Recovery"
But when i press"Fastboot Protocol" , doesn't do anything ?
For your references:
Steps of instruction I receive from Jide offical support so far....
1) have ADB and Fastboot running, I download the Minimal ADB and Fastboot[/URL])
2)Download Remix OS 1.5 ROM[/URL]
3) Unzip the downloaded zip file ( SK1WG.zip ) and go to the folder
4. Connect the Remix to the computer via USB.
Make sure the fastboot binary is in your PATH ) or that you place the recovery image in the same directory as fastboot.
6. Open a terminal on your PC and reboot the device into fastboot mode by typing adb reboot bootloader or by using the hardware key combination for your device while it is powered off.
7. Once the device is in fastboot mode, verify your PC sees the device by typing fastboot devices
-If you don't see your device serial number, and instead see "", fastboot is not configured properly on your machine. See fastboot documentation for more info.
-If you see "no permissions fastboot", make sure your UDEV rules are setup correctly.
8. Clean the existing data by entering the following command: fastboot -w
9. Flash images onto your device by entering the following three commands:
-fastboot flash system system.img
-fastboot flash recovery recovery.img
-fastboot flash boot boot.img
10. Once the flash completes successfully, run the following command to reboot the device into recovery to verify the installation.
-fastboot reboot

did u download the correct fastboot? you need Android 5.0 to get Remix 1.5

That makes no sense what so ever.
Maybe it would be better to ask what platform he is using to flash his device with, as the instructions he has copy and pasted refer to Linux (udev rules)

it makes sense to me cause you have download the correct Android SDK to work on certain Android platforms.
https://developer.android.com/studio/releases/platforms.html
To compile your application against a particular version of Android, you must use the SDK Manager to download and install the SDK Platform for that release.

when you turn it on,it seems you do not have the minimum knowledge required to flash a device... you should stay away from downgrading it or study adb and fastboot videos and tutorials on google and youtube before doing anything.if you do anything wrong and brick your device,the warranty will not work,any bad flash could void your device warranty.

fastboot reboot

When I type: adb devices
I got:

On the Tablet side:
Bootloop only
But I can still press "Vol up + Power" and see the following menu

Need help, bricked my 3s

Was supposed to flash CM13 Rom. I did a full wipe including system via TWRP.
Before flashing I decided to reboot into recovery, but it didn't. Only gets stuck in the MI logo now. Can't boot into recovery anymore.
I can go into Fastboot mode. Tried flashing twrp via ADB but whenever i type 'adb devices' in command prompt it says device is offline.
Tried to enter EDL via ADB in fastboot mode, it gets stuck at 'waiting for device'.
When plugged in PC, it gets detected as USB ADB interface
Bootloader was unlocked prior, was on xioami.eu ROM before this. I have TWRP system backup of last ROM installed.
Hoping someone can point me in the right direction on what to do next. Very much appreciated, thank you.

Hi Supdow,
I was facing with the same issue and I also thought I bricked my phone... No worries. To solve it is very easy, just unlock your bootloader again with Mi UnlockTool. Than you have access to your recovery again.
Good luck!

Was able to unlock bootloader again, but I still can't access recovery. I may have forgotten how to exactly do this since the last time I did it. What do i have to do after unlocking bootloader? I tried flashing TWRP via fastboot but it only gives me an error.

So you have a few options
1. Hold volume+ & - and power (if you have twrp)
2. Take fedosis twrp 3.1 and installer, put twrp 3.1 into extracted installer folder, then shift+right click on installer folder, open cmd, then type
fastboot flash recovery twrp_name.img
fastboot boot twrp_name.img (or do step 1)
3. Just flash dev/stable with miflash (recommendation: go into fastboot, then like step 2 go into cmd and type fastboot oem edl then flash mi rom)
Hope this helps

Fine i ll type down steps in max detail for you.
Go to developer options, enable usb debugging and oem unlock.
download platform-tools by google. (adb)
Extract it. Say at C:\
Now install drivers for your phone
open cmd and navigate to the folder where you extracted platform tools. Follow the code.
Enable usb debugging from developer options
[/LIST]
Code:
cd C:\platform-tools
adb devices
a device and some number should show up with an online status
Code:
adb reboot bootloader
fastboot devices
again, a device and number should show
Code:
fastboot oem unlock
fastboot reboot
if it says success,bootloader is unlocked.
download a recovery.img specific to your phone. rename it to say twrp.img and place it in the same folder as platform tools.
Code:
adb reboot bootloader
fastboot boot twrp.img
the recovery will boot. this is a temporary boot and will wipe off on a reboot. You can also flash the recovery using fastboot flash command.

Z17S (NX595J) Unlock Bootloader & TWRP

Hi, I'm new to this phone. Just got it 1 week ago. I tried to find any related information on the bootloader unlock and custom recovery, but it is very limited. I think maybe this phone is not well known. I would appreciate if someone can provide me the way to unlock bootloader, flash TWRP and roots. I can't live without magisk and viper4android. Thanks.

Here ya go,
1. Download and install minimal fastboot adb
2.Download TWRP rename it Recovery and move it to minimal fastboot adb folder
3. Unlock bootloader, in fastboot enter the following code : fastboot oem nubia_unlock NUBIA_NX595J
4. then also in fastboot: fastboot flash recovery recovery.img
5. you may need to format data in TWRP to get it to boot up !
Enjoy your new life !

thanks

Hi, I've tried numerous timed and it always won't pick up the command of unlocking bootloader. It always stay in the fastboot menu. I've toggled the 'OEM Unlock' function in the developer setting, as well as the USB debugging. Any idea why the device won't pick up that command?

Is it changing to unlock after you enter the command?
If so flash twrp then boot into recovery ...

Nope. It doesn't respond to the command in the fastboot. It just shows the fastboot menu. My adb is written 'waiting for device.... '.

I'm having the problem. Unlock is not sticking to unlock. The unlock works and the flash works but as soon as you try and reboot into recovery it hangs at a blank screen no twrp. Console says waiting for device and stuck. next time I go into bootloader it says locked. The count is 3 for unlock count is there a limit? 7-6-18 Nubia Z17 NX591J WIn 10.

I don't understand? Appears not locked? It is locked. Now I remember when I flashed my Star N997 the developer said that there is a unlock bit that has to be turned on in the process of unlocking. I think this may be the case here since it unlocks until a reboot. I am deep concerned that after a unlock count of 3 the phone will not boot anymore. Do you know anything about these things? Another thought is does the USB C need different drivers and should it be plugged into a USB 3.0 outlet?

TWRP will flash only when it's unlocked so even if it's saying it's locked go by what you can do with TWRP

I did it several times and never had a problem

i was looking for camera.apk file from Nubia Z17S phone from Stock ROM, can anyone upload it here..it should be located in system / app or app-pvt folder, you can copy using Root Explorer tool.
pls. let me know...

I'm having problems unlocking the bootloader. Has anyone got the proper TWRP for this phone? I can't find it. The one I have says FAILED (remote: Requested download size is more than max allowed). Thanks

hello links no longer works. Someone could give me back the TWRP and minimalb fastboot adb

For anyone's information, TWRP will not boot in recovery while the phone is being charged. Unplug first. You will just get a black screen.

i am also experiencing the same issue.. where can i find the drivers for this phone nx595j? or how do i uninstall the drivers for it?

[UPDATED] Mi A1 Not detected in fastboot.

Trying to unlock my Stock Mi A1.
Code:
adb reboot bootloader
: Phone reboots in fastboot mode/bootloader.
Code:
fastboot reboot
: Waiting for any device.
Code:
Fastboot devices
: Returns blank
I have installed Xiaomi adb drivers
I have installed quallcom drivers.
still nothing happens.
allow bootloader oem unlock option is enabled in dev settings.
What am I doing wrong?
Update: after some fiddling, I noticed that in Windows update there was an update to android drivers in other updates section. Did that and phone showed up in the fastboot. But its still hit and miss. Sometimes it shows up. Sometimes it drops connection and I have to disconnect the cable and reconnect to get it back. But overall its working out.

The bove link does not answer my question in any way. My issue was phone not showing up at all in fastboot. The above mentioned link is a general guide to unlocking. Not troubleshooting.
Anyways I got the issue solved by doing a driver update using Windows update.

I understood you wanted to unlock the bootloader.
to enter fastboot mode power+volume down button.
.\adb reboot fastboot
.\fastboot reboot recovery

NO.
That was not the issue. if you read the post, you'll see the problem is completely different.
