Fastboot error (trying to flash remix OS 1.5) - Remix Ultratablet General

I busted out my old remix ultratablet and am trying to downgrade to remix os 1.5 (because 2.0 is buggy slow and missing features)
I have all the nessecary files and drivers, usb debugging is enabled
I have fastboot installed, fastboot detects my device fine, and i can run reboot commands through it and those work
but whenever I try to put in a command to either wipe or re-flash the device (anything that needs storage access) it gives me a failure... without an error
example:
when I put in" fastboot flash system system.img"
target didn't report max-download-size
sending 'system' (585702 KB)...
FAILED (command write failed (No error))
finished. total time: 0.004s
Any ideas?
all help is greatly appreciated

Change USB port.
Update adb and fastboot

Please how I can unbrick my phone and reinstall the firmware
Obs. My bootloader is unlocked and I'm using TWRP recovery
Is your phone really shows Unlocked in red color when it's in fastboot mode?
Was your phone rooted, if yes, with which method?
You should try doing:
fastboot erase cache
fastboot erase userdata
These commands perform the same thing as Factory Reset do.
If it's not working, try to do the "dload" method with your original firmware your phone was shipped with.
Create a folder, called "dload" in your sdcard root, put the UPDATE.APP file of the firmware in it, and without connecting it to PC, press Vol + and Vol - and Power button until it starts flashing the firmware, and see what happens.
In later days, we've got a lot of troubleshooting topic opened up with your problem, the users cannot flash even with unlocked bootloader, and yet, there's no real solution to them.
I suggest that you use Windows 10? If I'm right sometimes this version of Windows cannot be used to flash via adb
I recommend you to use Windows 8.1 or 7 . My best way is of course using Linux

Yes, it shows PHONE unlocked in red name, and I've made the root using an app called kingroot
I've tried to erase cache and userdata using adb but I can't, still got the same error "FAILED (remote: Command not allowed)"
I can't make dload method because I don't have stock recovery, and I can't flash the stock recovery using adb because its keep saying "FAILED (remote: Command not allowed)".
I don't know what to do

I'm using windows 7 is this moment, maybe I try to flash using Linux later
Seems like all the guys with the same problem used KingRoot to root...that is the common thing amongst all.
I dont't think you need the stock recovery to update via the "dload" method, but I'm not sure.
If you don't have your original firmware's UPDATE.APP yet, download it, as well as the Huawei Update Extractor.
Load your file into the program, select ONLY BOOT.IMG, CUST.IMG(if it has one), SYSTEM.IMG and RECOVERY.IMG(optional, if selected, restores original recovery) right click on one, and press Create Flashable Zip.
Copy this to your sdcard and try to flash it.
I did not thest this above method, and don't know it the created flashable zip is really flashable, but I'm running out of possible solutions slowly.
Let us know what happens.

So I tried to create a flashable zip using the Huawei Update Extractor however, was not possible, it's showing the following message "no suitable files selected. Check profiles.xml"
I've tried also creating flashable zip manually and flash it using TWRP, but TWRP reboot every time I try to flash theses files, that's why I think dload method work only with stock recovery
Hello,
I created the script for flash via fastboot if you want try this method
Extract BOOT.img, Cust.img, Recovery.img, System.img and copy to fastboot folder.(attachment)
Enable developer options and USB debugging
Simply run file FLASH-ALL.bat file

Same issue with Huawei G6-U10
I'm having the same problem with Huawei Ascend G6-U10
Currently running on ROM b146, since it has some issues I was trying to downgrade or upgrade ( there is a b330 out).
I'm not an expert.
This morning I've unlocked the boot loader and then tried to flash a couple of different ROMs and I always get the same error message:
c:\adb>fastboot flash BOOT ./G6-U10verb330/boot.img

I'm guessing this is not a G6-U10 specific issue so if anyone can give any hint it'll be very appreciated.
Thanks.
I have the same problem with a honor 4x.
Rooted with kingroot. We haven't writing permission in /system. That's why we can't install the recovery. If you try to install superSU and update the binary I guess you get an error.
Now the question is: how we can do to make writeble /system with fast boot?
"mount -o rw,remount -t ext3 /dev/block/xxxxxxxxx /system" in terminal doesn't work...
Similar thing happened to me. Even if command for showing unlocked bootloader said it was unlocked that was false because I used Kingroot previously. Only thing that helped was to unlock the bootloader through fastboot again. Then it was really unlocked and I could flash recovery (in my case TWRP) which before I was unable to.

Have you tried it with linux yet?
And have you used the Update.APP and dload method?
Maybe a driver problem? Have administrator rights? And debug mode on?
Try to connect your phone (power on) to the pc and wait to be recognized. In cmd type this:
Code:
adb devices
It has to show you your serial number right? If doesn't your device is not being recognized by adb.
Next type:
Code:
adb reboot-bootloader
This will restart your phone into fastboot and now you can type "fastboot devices" like first command and it has to show you your serial number again.
Try rebooting into bl with this, not by plugin in the phone, and install the rom again
Huawei P8 Lite
Hello I have a problem with my phone. I do not know how to hell I fix it.
It says error cannot load system.img but still I can install boot.img and others.
I¨d tryed that "dload" with update.app doesnt work.
phone is Huawei P8 Lite
this is my first time here
Have you tried install it in twrp? You don't have a twrp backup of stock rom?
In this case if you go in the Huawei eRecovery you can restore stock rom and twrp will be overwrited downloading the last rom , i tried it with my p8 lite 2017 .

What are you using to go into fastboot mode? Is it ADB from Android SDK?? It turns out that using ADB from Android SDK lets you flash small files but not large files... I suggest you try flashing the file through Minimal ADB & Fastboot

Phone bricked after a crash - Flash modem_a error

Hello,
I have a Mi A1 since one week and I have already a large problem.
The problem began with a basic crash on an app (Facebook). The phone didn't respond and I turned off the phone.
When I turned on, the phone was stuck on the boot image (White screen with Mi Logo and Google colors). I tried to turn off and on several times but it didn't work.
I opened the phone and disconnected the battery but always the same problem.
Then, I booted the phone in fastboot and unlocked it via the command fastboot oem unlock. Then I tried to flash the stock ROM via fastboot. I choosed this version : Android 7.1.2 Nougat (N2G47H.7.12.7) because I had the last update (from : https://xiaomifirmware.com/roms/download-official-roms-xiaomi-mi-a1/).
Immediately i have this error :
Code:
fastboot flash modem_a C:\Users\Lau\Desktop\tissot_images_7.12.7_7.1\images\modem.img ||

"Flash modem_a error"
I tried to flash with Miflash tool 2017.7.20 but I have the same message, Flash modem_a error.
I also tried to boot the phone in EDL Mode with fastboot_edl, the phone reboot, I have a message your device software cannot be checked for corruption and then the boot screen (with the messsage "Unlocked") and after 30 seconds, I have the black screen with the droid and "No command" (https://scache.vzw.com/kb/images/google/pixel/android_system_recovery_no_command.jpg )
Someone should have an idea to restore the phone ?!
Thanks a lot !
That screen with "No command" is usually related to the recovery. If I remember well, once in that screen, you have to press and hold power button for few seconds then press and release volume up button to enter in recovery. By reading your post I can see you didn't even try the most easy thing: A factory Reset! Try to wipe data from recovery if you can enter in it.
The modem error could be related at the fact that you're flashing a firmware that is not global or for your country. Try to change firmware version and make sure it is the right firmware region.

Thank for the quick answer.
I thinked to the recovery but I didn't know how to acces. With your help, I found and I made a wipe data. It made 5 minutes I have the message Formatting /data.... It seems too long... :/
EDIT : I stopped the wiping, it's seems it was block.
When you spoke of an other firmware, do have you a link ? Here is the information of my phone

You must flash to system_a or system_b, "system" partition really doesn't exist.
Indeed, it's work now, it's flashing !
I noticed that for TWRP, there is also a "slot A" and "slot B". Is it new in Android ? Is there 2 kind of system ?

Can you boot into TWRP (use version 3.1.1-0 or 3.1.1-1 "fastboot boot twrp.img")? Do you see /data partition?
Yes I can boot into but I can't install it. Before I tried to flash manually, I was able to unlock the data partition but not anymore (Error : E: Decrypt took too long, killing process - Failed to decrypt data)
I have an access with adb shell.
Some people had luck with flashing persist.img from August update, you might try that as well. There is also a chance that your flash memory is damaged and you will need to visit a service center.
Okay try this.
Download the latest build (android n) from mi firmwares official page.
Unzip the file (http://en.miui.com/forum.php?mod=viewthread&tid=1415168&extra=page=1&mobile=2)
Download miflashtool (http://en.miui.com/thread-807252-1-1.html)- guide & tool.
Past the path in the tool.
Click refresh
Click flash
Boom your good.
Make sure to select clean flash and lock.
ADB and fastboot should be installed.

I tried to wipe via TWRP but it blocks on "Formatting Data using make_ext4fs...".
I think I'm good to send it at a service center...
There's a TWRP backup of first beta build oreo.Try restoring it.
Same Problem.
inally he managed to flash the ROM action, thank you very much to everyone for your patience and help, especially PALMATRON and fosco_
He used the tutorial of this link: https://xiaomifirmware.com/roms/down...-xiaomi-mi-a1/
1. Tools Download r26 for Windows.
2. Unzipped the instruments on disk C of my computer.
3. Unzipped the files of the last ROM available for the Xiaomi Mi A1 in the folder C: \ Tools so that the Images folder and the flashing scripts that come with the ROM are included in it.
4. Then double click on flash_all.bat to delete everything and just leave the boot loader open.
5. Automatically start flashing and take about 10-15 minutes and voila!

Try do with clean and lock or just clean i was have the same problem and i fix this only with miflash and after when my mi a1 restarts on boot i copy with terminal persist.img
thanks a lot
Saved my life, thanks. The rom on this link works PERFECTLY - my Mi A1 was stuck on botlooping after a fail tentative to root it.

Dang now its totally bricked after the flashing failure... cannot boot up. what should I do? send it back to Essential?
What do you mean by can't boot up? Do you see boot animation and have you tried to go back to fast boot or recovery?

Try different USB ports and cables. When 8.1 came out I had to swap my cable and change the port I was using on my desktop, for some reason the cable I had been using and the port I had been using since I got the phone was no longer adequate. There were a number of other people having the same issue. Some commands would look to complete properly, but following up with the same command (something un-damaging like fastboot --set-active=a | fastboot --set-active=b) would either error again or show that the 'completed' command hadn't actually done anything. I switched cables/ports around (ended up with an Antek USB-A to USB-C cable in a USB3.1 port) and everything worked properly.
If you're trying to flash a stock build image from Essential, you will probably need critical unlocked because those images do contain a bootloader that gets flashed, and that is secured behind critical.

What cable are you using?
Do not use the cable that came with the phone!!!!!
We are screwed mate, I am on the same boat with you. Essential took no responsibility and offered a 200$ replacement device. The phone doesn't power on anymore and no light indicators are working, so hard bricked.
I had a Asoip screw up(did not disable password) and was only able to get fastboot. Had to see what slot was active and flashed to that slot that was active boot.img,twrp,Asoip and was back up and running. My bootloader was unlocked. I read through all the posts and peoples screw ups and was able to get it up and running again in a day. I never posted as I wanted to learn it on my own. Good luck.........

What cable did you use while connecting to your computer?
And what is the status now? Are you able to turn it on at all by volume and power key combination?
same here. The phone doesn't power on anymore. btw I used the usb-c TDB cable came with my MacBook pro.
I sent email to essential and they say they can't help me since I tried to flash custom rom...

and pressing the volume down key + power key at the same time doesn't work?.. what happens when you plug your phone into the charger? does it vibrate?
ive had fastboot command problems previously myself with this device and found that the usb port can play a pretty large factor. Swapping usb ports and reattempting to run the commands (as others recommended may be useful) make sure you are using latest version of adb/fastboot and have up to date drivers installed for the phone.
Look at the rooting tutorial there is information in there about swapping active slots (the essential has both a and b paritions) if you set the other slot as the active slot you may be able to regain some communication within fastboot (i would suggest you verify with fastboot devices prior to attempting to flash to partitions).
Additionally you should be able to still recover back to stock without custom recovery using the default recovery partition. I would think that if you are able to access the bootloader you should be able to access the default essential recovery partition. If you can access the standard recovery you should be able to factory reset the phone and sideload a new rom (id suggest the default factory image from essential until you can get back to square one)
I'm in the same boat. Tried to flash twrp after upgrading to 8.1 and got the same Error flashing partition, and now I'm stuck on the bootloader.
I've found that if I lock/unlock and lock/unlock critical it will let me flash the stock 8.1 boot and every other partition except for system and vendor, but gives a flash write error for those. I'm still unable to get past the bootloader.
Essential basically said I'm SOL. $200 out of warranty replacement assuming I live in the US, which I don't.
Mine was doing this too, but it was only a few days old so I returned it. I'm pretty sure it's defective flash memory.
My phone was doing this exact thing. Botched factory installs rendered my phone hardbricked.
Tried a thousand+ things to get it to turn on to no avail. LUCKILY I bought it second hand and have no warranty D:
I want to cry

Not able to flash Recovery via fastboot

Hi Guys I am Having a problem with my Asus Zenfone Max Pro M2 (X01BDA) , I am not able to flash Twrp or i can't even flash anything via Fastboot.......
When I type the Commands in my PC i get this error :-
While flashing recovery :-
C:\adb>fastboot flash recovery recovery.img
Sending 'recovery' (29664 KB) FAILED (Write to device failed (Invalid argument))
fastboot: error: Command failed
While booting Recovery:-
C:\adb>fastboot boot recovery.img
Sending 'boot.img' (29664 KB) FAILED (Write to device failed (Too many links))
fastboot: error: Command failed
i have tried everything but still does'nt work Please help !!!
Check if you are entering the file name correctly with "fastboot flash recovery recovery.img"
Here in recovery.img instead of "recovery" write the filename of the recovery you downloaded.
Is your bootloader unlocked?
same problem here... can't seem find the solution. please help anybody. bootloader has been unlocked, all the name type correctly. but it just FAILED (Write tot device failed (Unknown error)) and the phone suddenly says press any key to shutdown.

Try this:
1. AMD Bug? - https://forum.xda-developers.com/t/fix-fastboot-issues-on-ryzen-based-pcs.4186321/
2. Switch Device from "Charging" to "File Transfer" Mode
3. Install the latest Device Driver or Universal USB Driver - https://www.androidfilehost.com/?fid=2188818919693784734
4. Placed the latest platform-tools with the Img File directly under the C Drive
5. Try another USB Cable
6. Use another USB Port (USB 3.0 Port to USB 2.0)
7. Try to execute Fastboot Command without connecting your Phone,
and once it says "waiting for device" plug in your USB Cable
8. Windows: Click "Change advanced power setting" on your chosen Plan and expand "USB Settings". Under "USB Settings" Section, expand "USB selective suspend setting" and change it to "Disabled" for On Battery and Plugged In.
9. Try another PC
Code:
adb reboot bootloader
fastboot devices
fastboot flash recovery recovery.img
I hope it helps (∩_∩)

Fastboot flash not working! "target didn't report max-download-size"

I am using the OnePlus 7 port for zenfone max pro m1. I was trying to change my recovery from twrp to orange fox recovery but I was unable to do so. It gave me the following error
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery D:\recovery.img
target didn't report max-download-size
sending 'recovery' (28872 KB)...
FAILED (command write failed (No error))
finished. total time: 0.034s
I tried to flash the orange fox recovery image through twrp and it got flashed, since then my phone doesn't boot into recovery. it gets stuck at the asus logo. I tried to reset my phone to factory settings using the stock firmware but when i run the "flashall_AFT.bat" file, my phone shows the message "press any key to shutdown" and there is no progress in the command prompt window. Now I cant boot into recovery mood and cant flash anything through fastboot. Anyone has any idea on how to fix this issue?
If i get these message, i am sure, the usb-port is incompatible for the fastboot (maybe the usb3 and fastboot incompatibility, but i'm not sure). Try to use some old usb-hub between phone, and PC.
