Hi All,
Good day.
Need some help regarding the error I encounter when flashing raw file. The fastboot in my ZF2 text also turns to red which I guess there's something wrong with my zf2. Also when trying to use XFSTK downloader, I get error also. Kindly refer to the images below. Hoping someone could help me regarding this. Thank you so much.
Btw, my phone is currently on Stucked Asus Logo.

very first of all stay away from xfst if you are able to go into fastboot
download raw firmware. after that i will tell you commands you have to run step by step
I already have raw file but when I try to flash the raw file via Asus Flashtool, I alway get GPT command failed error.

2. fastboot oem erase_osip_header
3. fastboot oem erase_token
4. fastboot oem start_partitioning
5. fastboot flash /tmp/partition.tbl partition.tbl
6. fastboot oem partition /tmp/partition.tbl
7. fastboot erase system
8. fastboot erase cache

first boot may take long time. so have patience
GPT = Grand Partition Table
Beyond my knowledge unfortunately .
Keeping an eye on this thread to see if theres a fix .
Can you describe how you got into this state ?

In other words, my device really become a bricked?
If I get UFI BOX it means that I may be able to repair it.
But UFI BOX is very expensive for me.

Did you unlock your device first with "fastboot oem unlock"?

Yes i did this before, i was running on Remix OS
I don't know if this is of relevance but there were new fastboot commands introduced from Android M (?) and I have recollection about "partial unlock" - two flags required to be set and if only one was set it could be reported that the bootloader was unlocked but fastboot saw it as locked. Above may be totally wrong.
Here's the difference between old and current fastboot commands. Note the new lock/unlock commands
Code:
************************ OLD **************************************
commands:
update <filename> reflash device from update.zip

been flashed to is set as active.
Secondary images may be flashed to
an inactive slot.

flashing lock Locks the device. Prevents flashing.
flashing unlock Unlocks the device. Allows flashing

bootloader-related partitions.
flashing lock_critical Prevents flashing bootloader-related
partitions.

Hi, I'm just wondering if you were able to fix your tablet. I ran into the same problem as you here and am not able to find a solution to it.
Hi !!
Sorry for bad news, but i didn't found any solution since my Pixel C was bricked. Maybe there is a solution, but I dropped it before finding it.
I hope you find something to fix it !
@viii_xvi Are you using "Minimal ADB and Fastboot" as shown in the post you quoted by -Yazh- ? The current (?) version that I can find is 1.4.3 and that looks to be "2015".
For the current versions of adb and fastboot and the revision history, 12 since October 2016, see https://developer.android.com/studio/releases/platform-tools.html

No. I used the 15 second ADB and Fastboot installer. I'm pretty sure it works fine as I can use fastboot commands.

There are Youtube videos on installing Android Platform Tools and a web search for installing Android Platform Tools with your o/s will find many hits. You need to know you are installing just the platform tools - some of the guides assume you are installing or have installed the full Android Software Development Kit (SDK).
Assuming you are using Windows then the simplest method is to copy the contents of the zip file into the current location of your "15 second" files. This ensures that you can run the new version of fastboot with the folder path you have used previously. In file manager "find" fastboot.exe and that will give you the folder to unzip ALL of the platform tools files. You will know if you have done it correctly if you get requests to overwrite existing files when you unzip the files.

I've followed the instructions so I'm confident I did it correctly. Despite this, nothing has improved. I still can't flash the stock ROM or a custom recovery in fastboot.
What I've noticed from updating the fastboot version are some new commands I found when I entered "fastboot -h"
Code:
fastboot -h
commands:
reboot [bootloader|emergency]
stage <infile>
get_staged <outfile>
options:
--skip-secondary
--skip-reboot
--disable-verity
--disable-verification
--unbuffered
--version
From what I've tried, all the commands in options returns

Hi, Did you tried to flash with the oldest stock rom of the pixel C ? Because it uses older version of fastboot so maybe it will work. I has also the same problem as you but hopefully twrp still worked so i could flash another system image.

I have now tried to flash the earliest factory image and am disappointed to say the bootloader did not flash and so I wasn't able to complete the flashing.
I don't think the problem is the fastboot version. It may be the bootloader itself. I've read someone describe this problem as "Broken fastboot (bootloader) security." I think the problem is that, when unlocked, the bootloader would return the same messages as if it was locked. The security of the bootloader still thinks it's locked and not allow flashing of any images. Also that locking and reunlocking does not improve the situation. This would explain why, when bootloader is unlocked, I get "remote: unsupported command" and "remote: image verification failed", the same as when I try the same commands when the bootloader is locked.

I'm assuming you have the latest version of TWRP installed. IIRC, there should be "Fix Fastboot" in advanced options. If indeed you have the same problem I had, pressing this should fix the problem. I don't know anything beyond this as I never got to find out what happens afterwards.

I believe I'm not qualified to help you as I disposed of my tablet months ago. All the advice I've given is off of memory and may not be accurate. That being said, I won't help you anymore in fear of giving inaccurate information that may lead to bricking of your tablet.
I have a pixel C, flashed with latest 3-rd pixel experience before, someday i tried to flash back to factory image, hit the same trouble like this topic, i came here several times before, no solution, today, i found another article about this , it's solved my trouble.
sorry i am new here, i couldn't share the outside article link.
would like to share what i did on my pixel c.
1. root your pixel c
2. adb shell //this command could be executed under recovery mode too.
3. su
4. fwtool vbnv write dev_boot_fastboot_full_cap 1
5. adb reboot fastboot
then you could flash anything you want.
I had this just now - I finally got fed up of my Pixel C being so laggy and also chrome opening up as blank pages (I switched to brace to fix this, but it's abit crashy).
Anyhow I found that after
adb reboot bootloader
that
fastboot flash recovery twrp.img
was failing for me in the "Writing" stage
I discovered that the fix was to use
adb flashing unlock
then it will ask you a question (power button to confirm and one of teh volume keys to cancel).
after this it spins with erasing for a while and then comes back to fastboot after which
fastboot flash recovery twrp.img
Worked, after this you get an annoying 30s delay for each restart, I think that can be fixed by
adb flashing lock
I'll verify this when I've finished flashing a usable ROM to my Pixel C...
I have unlocked bootloader. And flash the official recovery to get Naugat OTA but after updating. I am seeing "ID : bad key " instead of "ID : N/A" which is written in previous version of OS.
Any one know what it really meant.?
Try to boot in qcom or bp tools mode via menu fastboot, then restart the device. In my case, at the restart it shows "ID: N/A" Again. Another Theory is that you can get the "N/A" message after a hard reset o format data vía TWRP. I do both with the same results. Maybe a encryption mismatch.

Do you mean bad boot image in the sense of it won't boot or just the warning screen every time you boot. If its the second one you can fix it (almost) completely by flashing a modified logo.bin. I got those in my signature second thread if you are searching for that. Would be strange if your boot image couldn't boot up.

Same, and cant seem to flash at all
I'm having the same trouble here.
The main problem is that it seems to be related to the impossibility to flash again or install new rom on the device.
When i try to follow the typical procedures on cmd, i get messages like:
>> writing 'partition'...
>> (bootloader) Security version downgrade
>> (bootloader) Image primary_gpt failed validation
>> (bootloader) Preflash validation failed
>> FAILED (remote failure)
And then I can't seem to move on to another rom (and relocking the device, as I wish to do after all this).
(when i said typical procedures is that i found on many places, such as the motorola official website, https :// motorola-global-portal.custhelp.com/app/standalone/bootloader/recovery-images#)
FLASH AND RELOCK YOUR DEVICE
After downloading the image for your device:
Make sure you have a Moto Pure Edition or a Developer Edition device.
Make sure you download the corresponding recovery image from the above portal.
To flash, put the phone in fastboot mode:
1. Power OFF your device
2. Then Power ON + Volume Down
Alternatively, you can reboot into fastboot mode if you have adb...adb reboot bootloader.
Next flash the images using fastboot:
$ fastboot flash partition gpt.bin
$ fastboot flash motoboot motoboot.img
$ fastboot reboot-bootloader
$ fastboot flash logo logo.bin
$ fastboot flash boot boot.img
$ fastboot flash recovery recovery.img
$ fastboot flash system system.img
$ fastboot flash modem NON-HLOS.bin
$ fastboot erase modemst1
$ fastboot erase modemst2
$ fastboot flash fsg fsg.mbn
$ fastboot reboot
You also have the option to erase all the data on your device with
$ fastboot erase userdata
$ fastboot erase cache
After performing this sequence, you can relock your device with
$ fastboot oem lock

Try typing "fastboot oem fb_mode_clear" inside the bootloader.
So when I got this device I went to root it and found there's not very good documentation on what to do to get root and recovery installed so after many boot loops and reinstall of firmware here is what I did to gain root and TWRP and have a stable environment. You will need to use ADB & Fastboot commands please install either this : https://forum.xda-developers.com/showthread.php?t=2317790 or https://forum.xda-developers.com/showthread.php?t=2588979 or you can install from here: https://developer.android.com/studio/releases/platform-tools. you will also need the Motorola drivers located here: https://support.motorola.com/us/en/solution/MS88481. Once you have obtained these you can proceed with the bootloader unlock. I have the unlocked version of the Motorola G7 Power so I was able to fallow the sets here: https://support.motorola.com/us/en/bootloader/unlockyourdeviceb. If you have a different variant I'm not sure if your able to unlock your bootloader please try and let me know in this thread. I AM NOT RESPONSIBLE IF YOU SCREW YOUR DEVICE UP OR FOR ANY DAMAGE TO YOUR DEVICE
Bootloader unlock steps:
1. On your device go to Settings and to System, Then About phone and click " Build Number " until you unlock developer options.
2. Back out one step and click the Advanced tab and then click " Developer Options ".
3. Once in developer options " OEM Unlocking " turn off " Automatic Updates " and enable "USB Debugging".
4. Once you have done USB Debugging open the start button type "CMD" and open a command prompt.
5. Once in command prompt type " adb devices " make sure you authorize the pc on the phone. then type in command prompt " adb reboot bootloader "
6. Once in bootloader type in command prompt " fastboot oem get_unlock_data " from here fallow the directions on the Motorola Bootloader Unlocking page: https://support.motorola.com/us/en/bootloader/unlockyourdevice
7. Take the number given to you by Motorola and type in command prompt " fastboot oem unlock CODE FROM MOTO " then enter the same command again and your device will be bootloader unlocked.
TWRP & Magisk install:
This is where I found it to be difficult to get things right either I would bootloop or I wouldn't be able to unencrypt my sd card in TWRP so I couldn't read things right all sorts of dumb issues. All the files I used are attached so please let me know if this works as well as it did for me. Please download the TWRP .img file it was too large to attach: https://dl.twrp.me/ocean/ Also make sure that your command prompt is in the directory of your stored files.
Here are a list of commands to get TWRP and install Root please be in bootloader mode to start this process.
1. fastboot boot twrp-3.3.1-2-ocean.img
2. In TWRP go to the wipe option and select the format and type " yes " once it has done that go back to the main TWRP page by hitting the home bottom and select Reboot and select Reboot Bootloader.
3. fastboot boot twrp-3.3.1-2-ocean.img
4. Once in TWRP adb push twrp-installer-3.3.1-2-ocean.zip /tmp/ then click install and navigate to the /tmp folder and install the TWRP .zip file
5. After you install TWRP do this : adb push Magisk-v20.1(20100).zip /tmp/ then navigate to your /tmp folder and install Magisk .zip file
6. After you install magisk you can reboot the system and let it sit it might loop once or twice but it will boot. I did the force encrypt disable with the attached zip file then i rebooted.
Also I found it best to do this with a fresh installed firmware that hasn't been booted yet I downloaded the firmware/ROM from here: https://mirrors.lolinet.com/firmware/moto/ocean/official/RETUS/ here is a list of commands to copy and paste into command prompt please make sure your device is in bootloader/ fastboot mode.

Well i messed it up some how. my phone would boot loop three times and then go back to the twrp screen. after 30 minutes of messing with it i gave up and factory reset it via the adb platform tools.
Got it to work but had to start fresh as said at very bottom using retus version, I did all that then step by step but i booted once just to enable usb debugging of course, already had oem unlock but then right back into recovery flashed magisk and disable dm verity both back to back before reboot and all went fine cant get ota ofc but surely better roms will start showing up soon and I wont give a crap about stock anymore.

I am gonna check one thing I had it all working another method before but after installing something thru magisk it soft bricked I think it was vanced youtube maybe also cant seem to find a way to get vipre to work sadly.
Question
Does this method bypass the screen lock password on the phone? I have this phone that is locked with a passcode, so I can't easily get it into developer mode. Sorry, I'm a total newbie to this but am trying to learn. Thanks in advance!
A tip for linux users. If you are getting "< waiting for any device >" after the "fastboot oem get_unlock_data". Ctrl-c to exit the command. Su to root and then "fastboot oem get_unlock_data".
I give up, SIM stopped working after multiple failed attempts at installing Custom ROMs, even so much as installing Magisk+force encrypt disable brings up Factory data reset screen. Now my SIM doesn't even work on another stock phone for some reason, since the ban that apparently exists, if applied, should be IMEI-only, and somehow it works on a Custom ROM+Magisk device of mine. Going back to stock with locked bootloader I guess
SIM stopped working on G7 Power = neither SIM from two different carriers, one that's never been on a rooted/unlocked bootloader phone, don't even show up as a grey signal icon, tried both slots.
My SIM not working on another stock phone (G7 Play) = not recognized at all, but at least it recognizes there's a SIM card in there, grey signal.
Working fine on G5 with Magisk, Xposed and OmniROM
So maybe I banned both the chip (?) and IMEI, but still for some reason it works on another bootloader unlocked phone

From what I've been able to tell, the SIM cards are locked via IMEI (from MetroPCS I assume?, cause that's what they do), and will appear invalid, but should show the phone number in the settings. It should also say out of service, unless inserted into the phone that it originally belonged to.
I have an E5 Play, and unlocked it using the device unlock app built-in from MetroPCS, after 3 months of service (maybe 6 I forget). After that, I could throw in other SIMs. But the phones those SIMs would come out of, they couldn't read the metro card. They said invalid. But it still recognized it was a card, and showed phone number in settings. Said out of service.
After realizing this, I found out you can change devices in the website real quick, and that should solve the "invalid SIM" issue.
Possibly some custom ROMs lack what restricts all this in the first place, and the Sim must be valid because it's a SIM, in service, and the proper network. No clue there. What carrier are you on?

The thing is, "stopped working" literally, it doesn't have out of service, phone number, no signal, not even the "emergency calls only", heck I can't even find my IMEI in settings nor *#0606#, I think that's what's causing the problem. This SIM also came from that Custom ROM device (originally inserted there, but bought as a standalone data plan)

If you're talking about how it showed up like that on the G7 Play it used to work just fine in there, and no, that's not the original phone, it's just a phone I used to test if my SIM was still working

In this phone, G7 Power, it doesn't even recognize a card is in the tray anymore (unlike the G7 Play which at least knows there's one and G5+Custom ROM, in which it works)

Not that it's gonna help much but OI (Brazil), and if that's on Motorola support page my G7 Power is main phone already.
Is the force encrypt disable necessary? And what does it do?
So, I have successfully rooted my Moto G7 Power by using the method above, but i tried not doing the "format data" and fortunately, I have rooted my phone. For the 1st attempt, I kinda soft-bricked my device by doing the steps briefly, my phone would always bootloop back to recovery mode, but after not doing the "format data" step, it led to a success. So for anyone who are currently experiencing bootloop, flash the stock firmware to your phone and root it again by using the method above but don't do the "format data" step. (flashing the stock firmware would not re-lock the bootloader, so you can try to root your phone again easily.)

If it's same thing as always then you're still using "adb push magisk adb push Magisk-v20.1(20100).zip /tmp/". There's no "but I'm not", if it's indeed the same error as before you're messing up on the syntax. Make sure you've put Magisk inside Minimal ADB folder, rename it to magisk.zip and run "adb push magisk.zip /tmp/"
why is magisk pushed to tmp and not to internal storage . Why not just push magisk to internal sotrage and just install that way through twrp or that wont work. just wondering.
Anyone tried this on XT1955-4?

I LOVE IT!!! :good:
I flashed my redmi note 8 pro indian version with miflash, and downgraded to android 9 from 11 to install Ubuntu touch.
Ubports installer still didnt recognize my phone I am guessing cause it was Begoniain(india) as opposed to Begonia(Global) that is supported.
But my problem is I want to go back to Android, and I dont know how to go back, I didn't have any recovery tool installed before installing Ubuntu Touch, now Ubuntu is very buggy, and I can't seem to install TWRP. I have no other recovery tools installed, just fastboot. I guess I should hvae installed twrp before installing Ubuntu Touch. I want to know how I can go back to android or to any other supported custom rom.
Thank you.
whats wrong with fastboot?
Hey, thanks for replying. I followed the steps in this video
which is a very accurate video i found after searching for many videos.
basically he asked to download the right TRWP, then ADB platform tools, then the ADB driver found here

then using "fastboot flash recovery twrp.img" cmd command
this seemed to work for many people and everything went well. but I just can't boot to twrp it just takes me to the ubuntu touch screen and i log back in to UT

yes i think so, i think i should've installed twrp before that was the mistake, but i'll have to format this somehow
Did you try flash by mi flash the rom that you used to downgrade?
yes this is the first thing i tried, the same procedure i used to downgrade to 9 with mi flash, but when i do that it flashses in just 1 second, and gives success message, i was like it can't be that fast, but that happens everytime, so i figured somethings wrong. I turn on my phone and it's not flashed, it boots to ubuntu touch, but now even that's not happening, now it just keeps restarting after xiomi unlcoked screen.
i want to install a custom rom that goes best with my phone, i dont really want andriod to be honest, but need to have something installed to boot atleast, and I dont really mind if the phone goes dead, so i am not worried about experimenting on it

I believe that error message is misleading. It should mean
FAILED (remote: 'No such partition.')
you probably meant 'userdata' partition. however, I do not recommend fastboot erase cmd.
you should be able to enter fastboot mode with Volume Down button. instead of flashing TWRP into recovery partition (where it belongs) you could cheat bootloader and flash TWRP into boot partition instead. this will boot into TWRP recovery without Volume Up Button.
Code:
fastboot flash boot twrp.img
once in TWRP you can format Data, flash boot partition and install TWRP recovery.
probably easiest way is, create backup of boot + recovery from TWRP backup menu. that will create two files, boot.emmc.win + recovery.emmc.win in TWRP/Backups/<serialno>/<date> directory. just create another directory TWRP/Backups/<serialno>/my_files and place your files in there (rename boot.img = boot.emmc.win and twrp.img = recovery.emmc.win) then restore 'my_files' backup from menu.
then you can install any ROM from TWRP via System Image. Note that's android device, you can only install android. even ubports Ubuntu touch is not linux, it is just some gui build on top of android kernel to give you linux-like feelings.
