ME176C Fastboot Commands - MeMO Pad 7 Q&A, Help & Troubleshooting

Hi,
after upgrading to Lollipop, I wanted to downgrade to Kitkat. I think I flashed Kitkat's fastboot and what I only see after logo is:
"Fastboot Starting...
Fastboot Starting#1...
Fastboot Starting#2...
Fastboot Starting#3..."
currently adb doesn't recognize.
fastboot recognizes the device however,
the only command accepted is "boot". The others like "flash" doesn't work.
Any ideas?

USB Debugging DISABLED - How can I flash boot.img?

I'm trying to get my phone back to a custom ROM after abandoning it for over a year so I am having trouble remembering what I did...
USB Debugging is definitely off. When I go into a command prompt to flash the boot.img, "adb devices" returns no devices. The drivers all seem to be up to date - so how can I flash the boot.img? I can't get into the OS as I get stuck at the white HTC logo boot - soft bricked.

I would normally recommend RUU (http://forum.xda-developers.com/showthread.php?t=1562890) to revert to stock firmware and then turn on USB debugging like normal, but I'm worried that your device may still be unlocked (then RUU won't work).
Hold the phone, when you boot into the bootloader, and select "fastboot", can you flash the boot.img that way? (command prompt: "fastboot flash boot boot.img", assuming your command prompt is opened in the same folder as fastboot.exe and your boot.img)

Seems like after I updated the drivers and mounted the device, I was able to get my PC to recognize the phone through ADB devices. I went back into the fastboot and flashed the .img and it worked. Thanks for your help.

The very first thing I recommend you to do, is to download the right recovery and install it via command
Code:
fastboot flash recovery recovery.zip
Let me know if you run into any further troubles.

Hi,
Frist in boot loader check your OS version it should be something like 2.19.401.2 or lower than this.
NB: ALWAYS TRY WITH MORE THAN 75% BATTERY, AND THAT FOR ANY CODE TO WORK PROPERLY, MAKE SURE TO SELECT FASTBOOT BY POWER KEY IN BOOTLOADER
Anyway, if you can enter fastboot, then you have some chance of recovering your device and because you have S-Off it is going to be a bit difficult.
First download this stock boot file : https://mega.nz/#!lEAVwRSL!wrP2hi6GEYLeJaPf2ssZo9wCtSi7E4yfyUHgh3Q3XSs
Then place this file in the ADB folder, then run command :
To flash boot file command is:
Code:
- Fastboot Devices (this command is important to know if the device is connected and accepting and responding commands)
- fastboot flash boot boot_signed.mg (assuming this is the name you saved the file with)
- fastboot reboot bootloader
Also download Stock Recovery: https://mega.nz/#!gVJE1Bxa!6SwXStAD8p-XlnQiPkRcdNo_ITFD1ykn-tN6wIBVi1I
Place this in ADB folder and run command:
Code:
fastboot flash recovery stockrec.img // (assuming that is the name you have saved the file with), only after flashing this you will know if the device has any OS, if OS exists it will boot up.
fastboot erase cache
Attempt and let us know how it went...Good Luck

How to get back to Android 8.1 from Android 9?

Hello, please help me with the following.
My Moto X4 (XT1900-7) recently got the Android 9 (Pie) update. Since then I have problems with wifi and it's always dropping. Because of that I reset the phone, but now I can't even log into Play Store, because wifi keeps dropping all the time. I can't use the phone at all. Every guide I've tried getting back Android 8.1 back didn't work so far. Maybe the guides were **** or I simply didn't understand them. Also, my recovery mode doesn't even start.
I've downloaded "PAYTON_OPW27.57-40_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml". Would that be the correct version to install?
Please help.
Thanks in advance.

This one:
PAYTON_OPWS28.46-21-16_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
but two things:
1) Your bootloader needs to be unlocked. If you have a locked bootloader and try to go 9 -> 8.1 you are bootlooped.
2) You will still get prompts to upgrade to Android 9. You can ignore them but they won't ever go away.
Yeah, I first need to unlock the bootloader, but that's where the problems start. I found a guide on motorola web page: motorola-global-portal[.]custhelp[.com]/app/standalone/bootloader/unlock-your-device-b
I've downloaded Android SDK (1 GB??!) and installed it. Then I've installed Motorola Device Manager. I've set my X4 to Fastboot Mode. The next step "On your desktop, open a command prompt or terminal, and go to the directory where you installed the Android SDK tools (or make sure fastboot is in your $PATH)" I don't even understand. How do I "go to the directory", and what's my "$PATH"? That guide is as bad as it gets. I doesn't explain anything.
Edit: I've tried it through minimal adb fastboot command and could get my unlock-key. let's see how it goes from now on.
Thanks so far.

I only get error messages when entering all the fastboot commands.
FAILED (command write failed (Unknown error))
I could flash it using my laptop now, but when turning it on it says "verity mode is set to logging" and keeps on rebooting in a loop. Then I tried using twrp and mount it using an sd card, but that gave me error messages. are you sure this version is the right one for me? How difficult can it be? I wanna smash the phone against a wall.

It is the correct Oreo firmware for your device.
Re-verify the commands you're entering to flash are:
Code:
fastboot getvar max-sparse-size
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot erase modemst1
fastboot erase modemst2
fastboot flash bluetooth BTFM.bin
fastboot flash dsp dspso.bin
fastboot flash boot boot.img
fastboot flash logo logo.bin
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system_b system_other.img
fastboot flash oem oem.img
fastboot erase carrier
fastboot erase userdata
fastboot erase ddr
fastboot oem fb_mode_clear
Bootloader is unlocked (the bottom of your fastboot screen says 'flashing_unlocked')?
Are you trying this in windows or linux?
I tried this version: PAYTON_OPWS28.46-21-16_subsidy-DEFAULT_regulatory-DEFAULT very often on my laptop (I guess it was a problem with the usb-ports on my normal pc), but I couldn't get my device to work. It always said "verity mode is set to logging". Then I tried installing PAYTON_OPW27.57-40_subsidy-DEFAULT_regulatory-DEFAULT once (with my laptop) and it worked without any problems. The only thing is, that the device now says it's not the correct os when booting.

This will display for everyone with an unlocked bootloader. I know it does for me.

But it didn't boot though. It showed this text and it kept restarting over and over again.
It's fine now with this PAYTON_OPW27.57-40_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml version, but I always get the notifications that I should update to Android 9. I don't have any wifi problems whatsoever.
Do you have a solution on how to really disable / block those?

i tried accessing the recovery but i get the same error msg.
i tried flashing every recovery img that exist for the red magic 3 but with no success
Flashing Unlock
Hey, make sure that you have first unlocked the bootloader with the fastboot command: "fastboot flashing unlock". Try it. It will erase all your data and do a reset factory and then you should be able to reboot your device normally. Also, it will let you flash the boot.img for root your device.

Did you let unlock bootloader and permitted the USB debbugin on the developers option before flash the boot.img?
Make sure you are using a USB 2.0 to connect your device to the PC. See if you PC recognizes the device into the fastboot menu with "fastboot devices", if doesn't, try reboot another phone with "adb rebbot bootloader", then enter "fastboot devices", your device should be listed into de the devices attached. Then try again entering "fastboot flashing unlock".

Oh, that could be a problem. Try to use this tool. I hope you can get your phone working again. If this doesn't works, try to flash the original boot.img of your firmware version.

Question [Fixed] ASUS logo stucks on recovery, only access to bootloader

Hi all,
I'm encountering a very annoying issue with my brand new Zenfone 8.
I wanted to install the last LineageOS image, but now my phone seems stuck.
Here are what I did:
- Unlocked the bootloader: success with the ASUS APK after a few tries (error 11000 and 11006 ans eventually worked).
- Rebooted to bootloader
- Entered into recovery
- Used fastboot to flash the vendor partition.
At this point, everything looked OK. But then.... :
- Powered off the phone and restarted to bootloader.
- Tried to enter into recovery to flash the Lineage Recovery
But at this point, I had a ASUS logo stucked on the screen.
I can't do anything with adb or fastboot commands.
I tried the method explained here (https://www.asus.com/Content/Android-13-Beta/) to rollback to stock Android 12, but nothing happened too: I looked at the shell script (I'm on Linux) and I reckon that it stucks on fastboot command (the phone is in the bootloader).
Any idea about what failed? The last command used (vendor partition flash) said "OKAY".
And especially, what can I do now? Any way to reinstall the ASUS recovery?
Thanks in advance guys.
Not quite sure what your status is if you say "can't do anything with adb or fastboot commands". I've flashed Zenfones a couple of times (my household has 3 Zenfone 8's on LineageOS) and I had one that went into ramdump. I recovered from that using fastboot to manually reflash all 19 firmware partitions, in both slots. That got the phone out of ramdump, and I got to continue the upgrade to the new LineageOS. So: if you can boot to the fastboot environment, then that would be a road that might leaed you out. But if you can't even get a response to the command "fastboot devices" then I don't know of a course of action for you.
To use fastboot commands I had to run the phone into bootloader mode, then to "recovery" and eventually "fastboot" (I'm note 100% sure but it's what I remembered).
Without that, I was unable to use any fastboot commands like device or flash.
And now the issue is that I'm not able to go to recovery/fastboot again, because I have just the ASUS logo and nothing else.
It looks like that the stock recovery was dead, but I don't know why - and I don't know how to fix/reset it.
From the bootloader you should be able to flash the raw image again, it should flash everything

Good to know - but with which commands/tools?
As I said, I was unable to use fastboot commands from my computer on the Zenfone bootloader.
On the bootloader page, I just have "waiting for devices" and noting else. I had to go into the recovery > fastboot to make the commands work.

On Linux and maybe macs too you need to run fastboot commands as Root (sudo fastboot devices) for example. The raw image script should ask you for your Root password for this reason
Yes I know - I well used sudo for all commands.
The ASUS script asks me for password but then does absolutely nothing - not even a print. I waited a few minutes and finally canceled.
For you, fastboot commands should work on the bootloader screen? (I ask that because the script starts by a fastboot command).

Yes, they work from the bootloader, I always run the script from the BL too. Ironically, I had issues running fastboot commands from fastbootd for installing Omnirom, so I did it all in the bootloader and all worked fine.
I am not sure I can help you more at this point, it looks like it maybe got interrupted mid flashing and now something is wrong somewhere. Maybe if you look inside the bash script file you can find the command that it got stuck on and run that manually if you manage to get fastboot command access.
Strange - they have never worked from the bootloader. I tried that before according to the LineageOS wiki. I thought it was a mistake and use the recovery > fastboot to do that. I dont like that - I hope it's not a local version of the Zenfone or something like that.
I'm not at home tonight but yes I'll try to find commands not requiering the fastboot command.
Unfortunately all commands from the script are using fastboot. And as "fastboot devices" sees nothing, I can't do anything.
I've tried from the bootloader screen (with start, recovery, poweroff option) - from the start screen showing unlocked bootloader warning and from the ASUS logo when I try to start the recovery. I've tried the commands/scripts with Linux and Windows: same result.
So :
- I can't use any fastboot commands.
- I don't have the ASUS recovery.
Speaking of the ASUS recovery, I've found screenshots on internet and they don't have a "fastboot" submenu (I'm not sure it's a Zenfone 8). May had I a different version?
I don't like that. If I don't have others option, I guess that the warranty doesn't work because the phone is unlocked?
I eventually found a solution! I've tried with my old OnePlus cable and fastboot commands start working from the bootloader screen.
I have no idea why my other cable was faulty (it can charge the phone and executes commands from the Recovery > Fastboot menu - but not on the BL screen).
Anyway my problem is now fixed.
Thanks all for help and support.
