Root for US Asus MeMO FHD 10 build v5.0.21

Well... Here it is.
I also have some script files i found and all the info you need to create your own pre-rooted rom using your current system files if you like that option better. I am currently working on a custom 5.0.1 rom.
READ THE WHOLE POST BEFORE YOU DO THIS!!!
I am only giving you a step by step process put into a easy to use reference guide to help you obtain "root" on your device. I am providing this "As-Is". If you read the whole guide and decide to try it on your own device just know that It may/will void any product warranty that you may have on the device if any. Any time you do anything to your tablet via fastboot or any other means you run the risk of "bricking" your device, or loosing all of your data. I am not responsible for any damage to your device, and i will not be responsible for any damage or loss that you may have as a result of this post, or any instructions that i give here. If you have any questions feel free to send me a message and I will try to help you out, if i can....
I looked and looked and looked through many forums without much luck, and I finally found out how to root the U.S. version ASUS MEMO FHD 10 that has been updated to 4.3 - V5.0.21 by using a pre rooted system rom. If you are not running that version you can go to” Settings - About Tablet - System Update” to update it to 5.0.21
First things first...
Fully charge your tablet, and make a backup of your system!!!
1. Make sure the tablet has a good charge. It will not charge while you are doing this, and who knows what will happen if it dies halfway through the process.
2. Turn USB debugging mode on in the "Developer Options" menu under settings on your tablet.
If you do not have the "Developer Options" menu just go down to "About Tablet" and click the "Build Number" button six or seven times and it will say "developer mode enabled", or something to that effect, and it will unlock the "Developer Options" menu for you.
3. Turn off your tablet.
4. Hold down the volume up button , and press the power button until your tablet turns on. It will boot into fastboot for you.
Connect your tablet via USB cable to your computer, and set it aside.
Now your tablet is ready to go and it is time to set up your computer.
1. To get your computer to recognize your tablet in usb debugging mode you need to install the intel drivers.
2. Download and install minimal adb fastboot.
3. Download the pre-rooted system rom, and then put that rom into the folder that you installed fastboot in on your computers hard drive.
4. I used minimal_adb_fastboot_v1.1.3_setup.exe to do this next part with no problems whatsoever. the only thing was I needed to type the .exe from the command prompt for it to work on my laptop. You might not need to.
Now you have your computer all set up, your tablet is all ready, and it is time to finally do some rooting.
1. On your computer, open up a command prompt, and navigate to the folder that you installed fastboot to.
2. Enter the following commands one line at a time into your fastboot window. (See transcript below)
fastboot.exe devices (Just to make sure your device is connected properly.)
fastboot.exe erase system (Optional I think? I didn't use it and mine works great)
fastboot.exe flash system us_me302c-v5.0.21-jb_4.3-system.gz (Replace with your image file name if you are using a different one)
If done right it should look something like this.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot.exe devices
1111111111111111 fastboot
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot.exe flash system us_me302c-v5.0.21-jb_4.3-system.gz
sending 'system' (771129 KB)...
OKAY [ 95.862s]
writing 'system'...
OKAY [ 74.116s]
finished. total time: 169.978s
C:\Program Files (x86)\Minimal ADB and Fastboot>
Click to expand...
Click to collapse
And guess what. You're all done…
Now just sit back and let it reboot a few times.
You are going to want to make sure you have a superuser app and enjoy…
Im not an expert but after a few weeks of hunting for it i finally found out how to do it.
Many thanks go out to everyone who worked on this for all of us, and if you found this post helpful please feel free to add some thanks.

Need Serious help Rooting the K1 Nvidia Shield Tablet on Linux MInt 18

(first, If im on the wrong thread can you help with asking a moderator to move it to the correct place, or how ever that would work? Thanks!!)
Im on Linux Mint 18 Sarah Cinnamon 64 bit
I'm trying to root my Nvidia K1 shield tablet. no idea what im doing and the more I research this the more confusing it gets. Seems like If you ran windows theres "Clear Cut & Right to the Point" instructions about how to do this on about 14 hundred pages of great info including great you tube videos which heavily explain it, in great easy to understand detail.
What Ive done so far.
installed ADB and BootLoader (but ive no idea how to actually use these programs yet, still figuring that one out)
I have sucessfully Unlocked the Device
Now im trying to flash the .img I hit this command (from terminal) and get this result
$ fastboot flash recovery recovery.img
target reported max download size of 100663296 bytes
sending 'recovery' (16384 KB)...
OKAY [ 0.658s]
writing 'recovery'...
OKAY [ 0.651s]
finished. total time: 1.309s
Now following these steps at this website http://developer.download.nvidia.co.../0_0_0_Factory/HowTo-Flash-Recovery-Image.txt
im on the:
$ fastboot flash boot boot.img
error: cannot load 'boot.img'
Now ive no idea what to do, how to fix this ,or even if im following the right directions. what I need is (im going to throw a nice Trump statement here)
Can someone explain how you root a Nvidia shield K1 tablet, start to finish, ON LINUX, and every step simplified along the way explained, PERIOD!!!!
Everyone starts to tell you how to do this, then they jump on a windows PC throwing me all off...
now my .img file is from this website https://www.androidfilehost.com/?fid=24269982087005399
its in my downloads folder if that matters??? Not sure but i think it does. If i need to move this .img file somewhere please explain how to do it, don't just say "oh your problem is you need to move it to /usb/local/ or something," and just leave it there. remember i need help, so if I need to move things and use commands please help me with that. thank you
You know I got my MCSE, MCSA, A+ SERVER+ NET+ NOVEL and I can write python Programs and im getting into Julia. I know DOS, & I feel im a power User on Andriod, and ive been using personal computers since the 1970's. But when it comes to linux, I cant even google my way out of anything, even if the problem is very minor and simple, still, I cant google my way out of anything on linux its crazy. I keep having to write on forums on threads to find the answer. Someone with my Creds, granted most were aquired in 2002, shouldnt struggle like I do with linux, the support is terrible, and I dont mean updates for software and hardware, im sure thats fine. But when it comes to user support and the documentation for instruction, you get pages of results that have more links then answers on the page to other peoples help pages, that link more to other pages. You cant just goto 1 page, get the answer, done finished your allset, NOPE LINUX does not work that way and its to bad, I see why most of the world doesn't use it.
Good analogy right here, if someone in your neighborhood is giving out free gold to anyone, you know ya whole villiage or town is going to be there getting free gold, ya well, if Linux was that good, the whole world would be using it, and there not, and its free just like the gold. So does that tell you anything?

settled that, smashed the tablet, going to mount it on my wall as a reminder for tech not to mess with me. and yes linux sucks balls!!!!

I suggest anger management and growing some sort of ability to wait periods of time before going all hulk smash... You waited all of 2 hours for someone to tell you you had already finished all you needed a pc for... After flashing the twrp recovery over adb all you needed to do was boot into it. you could have done so by shutting it off then holding vol down and power to get you to the fastboot menu then use the volume rockers to go to recovery the power button will be enter in this case and it should boot the recovery you just loaded.
From there you flash the super su binary you already downloaded and when you boot into the tablet after that you can load a apk from the google play store supersu is what i use then you are rooted...

Also just going to add the process is the same in mint/ubuntu as it is in windows. Getting fastboot/adb is the only difference, and it basically tells you how to do if you try using fastboot without it installed. Also make sure you are in the right directory and type the correct name or you get the cant load message.

Additionally as someone who had to learn linux cli on Red hat i would have to say vs ms dos about the same... if the op thinks mint is bad i have some old yellow dog and mandrake 7.0 disk i can send him. He does not know the pain of trying to find the drivers on repositories and such just to get the sound and Ethernet working... Had the issue of my realtek 10/100 card not working under linux but my 3com card would if i had preloaded the drivers...
I have tried unbuntu and mint both gave a very similar experience to installing windows. With the exception unlike windows i did not need to patch 1000 things before using it and everything just worked.
Also Android is linux...
SHIELD TABLET K1 RECOVERY IMAGE FLASHING INSTRUCTIONS
To follow the instructions in this guide, you will need adb and fastboot.
These tools are provided as part of the Android SDK:
http://developer.android.com/sdk/index.html
Before flashing this recovery image to your SHIELD TABLET, connect your SHIELD TABLET
via USB to the PC where you downloaded this recovery image.
Next, put your SHIELD TABLET into fastboot mode using one of the following methods:
SW method:
- Boot to android home screen
- Connect the device to linux/windows system
- Open terminal (on linux); command prompt (on windows).
- Type "adb reboot bootloader" in terminal/command prompt
HW method: (If you had done this after the part you loaded what ever recovery nvidia tried pushing on you it should have worked)
- Turn off the device
- Press "Volume Down" -> "Power", hold "Volume Down" and leave Power buttons till device boots
(I dont even know what this from nvidia is talking about)http://forum.xda-developers.com/shi...recovery-twrp-2-8-7-0-touch-recovery-t3257172 <--go to the xda first next time...
To flash this recovery image to your SHIELD TABLET, run the following commands from
the directory where you extracted the recovery image package. If this is the
first time you have done this procedure, you must unlock the bootloader (see
below):
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot erase userdata
fastboot flash staging blob
(Better instructions that i found on this place)
https://twrp.me/devices/nvidiahshieldtablet.html
adb reboot bootloader
(https://dl.twrp.me/shieldtablet/) Download latest here rename the .img file twrp.img maesure the file is in the adb folder...
fastboot flash recovery twrp.img
fastboot reboot
After boot you can issue this command
adb rebooot recovery
or
shut off the tablet
hold vol down then hold power
then press vol down until recovery is highlighted then push power button...
Unlocking the Bootloader<you needed to do this first>
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.

[HELP] Factory Reset from Settings while on Custom ROM

As the title says, I (without thinking) did a factory reset from within the settings menu while using a custom rom. My tablet boots and sits on the attached screen. I cannot access fastboot but while on the screen I have ADB access and can send commands. Also, none of the Volume&Power Buttons combinations will work. Please advise..

Thanks for the suggested thread, unfortunately after the "adb shell insmod /bootit.ko" command my tablet simply powers off and does not reboot. I read through the thread and saw that someone else experienced the same but there doesn't seem to be a resolution.

Will this work if I accidentally did wipe davlink in TWRP after I flashed a rom? I can get into TWRP but cant reflash rom and am in boot loop when I try to flash it says MD5 not found

Is that a serious question???
I used red size 6 type in that post to make clear what that trick is NOTfor.....
You must have done a little more than "accidentally wipe Dalvik" my friend. Dalvik would just get rebuild on the next boot if you wiped it.
The message that no MD5 is found is pretty normal if no MD5 is present, but it would not prevent you from flashing the rom.
My wild guess is that you somehow corrupted /data and it won't mount, but I don't really know because your post lacks anything that might be helpful.
Like specific information.
Try again.
Harder.

I'm still not sure what happened. I was flashing KatKiss-7.1_TF700T_015.zip and left my tablet on my desk. I ran out to the store and came home to my 6yo son holding the tablet and telling me it wasn't working. From what I gathered from what he said was he typed "yes" but wasn't sure what option he picked in TWRP. Going through options I think he picked the option to wipe cache dalvik after the rom was flashed but I am still not 100% sure what happened all I know is I'm stuck on Katkiss boot loop and when I go into TWRP to flash anything else it tells me failed no md5 or something along those lines

jmms1124.
Here is the instructions that I followed that restored my TF700T:
Download and install ADB, Fastboot and the required drivers - Download and run this cool little tool which has it all packed into one: [TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.1 - xda-developers (don't forget to hit the Thanks button)
NOTE: at the moment Fastboot seems to have issues with Windows 8
This awesome tool installs the ADB and Fastboot.exe to a folder on your C:\ drive (look for a file titled “adb”) as well as the corresponding drivers. This takes about 15 seconds to install following the prompts.
I installed the device drivers - if you have already tried to connect the tablet to your PC and it's recognised as a portable device you should be ok. If not, download the Asus Sync Utility from their support/downloads site and install it.
Download the latest firmware from Asus (Always make sure that you download the correct SKU version -WW, US etc.) and extract the zip twice so you access the blob file (a blob is a collection of binary data stored as a single entity) – copy and paste this blob file into the previously mentioned “adb” folder on your C:\ drive.
Reset the device with a paperclip/needle (about 2 cm down of the SDcard slot)
Power down the tablet and disconnect it from the keyboard dock.
Connect it to your computer via the original USB cable.
Push and hold the Volume Down key (left side of the rocker) and the Power key until you feel the tablet vibrate twice. Let go when you see the tiny script. Read it and it tells you that your tablet is now in Fastboot mode and you will see three or 4 icons (depending on the bootloader version). Select the USB icon to get into the Fastboot mode.
Your PC should acknowledge that a USB device has been connected (an audible indication) Don’t panic if the device does not appear under “My Computer” (as mine did not either – Fastboot will still communicate with it), you can go into Control Panel/Hardware and Sound/ Device Manager and you may see “Fastboot” icon, expand this and the device will be represented again by the “Fastboot” icon. Right click, select “Properties”, Driver tab and then select “Update Driver” and allow it to search automatically and update from the internet. This should then update and change to Asus icons. You now can be certain that you have the current device drivers.
In Windows Explorer navigate to the folder that contains your adb.exe and fastboot.exe
Win 7 press Shift + right click and select "Open command window here".
In the resulting command prompt screen type the following codes (those in bold):
C:\adb\ (or whatever the path to your fastboot folder is..)
fastboot devices (If that command returns a string of numbers and letters, you are good as gold. If it returns: "No devices found", fastboot is not working - yet - and you have to troubleshoot)
Followed by each in turn of the below, selecting Yes as required and allowing each to complete the process:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
The resulting screen should look something like this below – NOTE, I did make a couple of typos while I was attempting this which returned some multiple choice garble if this happens recheck you input instructions:
E:\asus>fastboot erase system
******** Did you mean to fastboot format this partition?

finished. total time: 1.460s
fastboot -i 0x0B05 flash system c:\adb\TF700T\blob - depending where you stored your blob, also this was the first time that I saw the loading bar appear on my tablet.
It will now go through the process of reinstalling your Android stock ROM and you should see the something similar to the following:
E:\asus>fastboot -i 0x0B05 flash system e:\asus\blob
erasing 'system'...
OKAY [ 1.731s]
sending 'system' (800935 KB)...

fastboot -i 0x0B05 reboot
E:\asus>fastboot -i 0x0B05 reboot
rebooting...
finished. total time: 0.020s
E:\asus>
I disconnected and rebooted My Asus TF700T and I now have a fully functioning Tablet with a stock ROM.
It has been reported that after completing this you may have some issues getting back get into recovery, hitting RCK and getting the dreaded dead Android (with a red triangle with an exclamation point in the middle). I have not attempted this but have been led to believe that flashing TWRP 2.7.0.1 via Fastboot works.
All acknowledgement and appreciation for this method should go to Buster99, a Senior Member of XDA Developers

And to Snoop05, also a Senior Member of XDA Developers for the awesome ADB/Fastboot/Driver tool.

To whom I am most grateful for the return of my tablet to a working state, I hope this works for you. Good Luck.
Thanks to Browndog181 for this great instruction he made.
Good luck to bring back live to your tablet.:

So you got a little software engineer in the house, eh? :cyclops:
For these little rascals you need Apple devices: Safely locked down so the average user cannot do much damage :laugh:
You can do the buster99 described in the post above, but I would leave that as a last resort.
Sounds to me as if your son formatted something and since nothing exciting happened after typing "yes", he tried pushing some other buttons, interrupting the format and corrupting the partition.
I assume you can still boot into recovery and use it and fastboot is also accessible to you. Correct me if wrong.
Use TWRP's build in file manager to check if you can see the contents of your sdcard. If you can, it was not /data he formatted, but /cache or Dalvik. If so, just format cache, wipe Dalvik and reflash the rom
If /data is not accessible you'll have to format it from the Wipe > Advanced menu. That process takes 1 hour+, so send your son out of the house on a play date or some such....
That you see "md5 not found" probably means the box for "Verify MD5" (or "Check MD5" or something similar, can't remember what the official TWRP had there) is checked on the Install page just before you flash. TWRP will abort the installation if it does not find a MD5 for the zip you are trying to flash if you told it to look for one...
Make sure that is unchecked, then flash the rom.
If none of this works, take screenshots or write down the error messages you get and post them.

Here are pictures of what happens when I try to reflash

Yes, /data and /cache cannot be mounted. Did you format them in TWRP?
Your version of TWRP is pretty outdated. You should update it to 2.8+ at the least, the last version is 3.0.2.
Did 2.7 even support f2fs? Can't remember....
Remember that if you format data you end up with ext4 file system and have to convert to f2fs again.

I think i'm sending my son to boarding school. I'm not sure if he formatted them he has no idea what he did I know I can only use external sd to try to flash should I get TWRP 3.0.2 to my extenal sd and flash that or will that not work since it may have to be reformated? and how do I go about that?

No man, you have a working recovery now. Fix your problems first, then update the recovery.
BTW, I don't even know if you can properly flash Nougatella with TWRP 2.7. Maybe it's YOU who should be sent to boarding school... :angel:
Ok, so go to Wipe > Format Data, type yes and place the tablet on a high shelf. Leave it alone for an hour plus, this takes a while (and make sure it has enough juice)
Then go to Wipe > Advanced > check Cache and swipe the button. This will take a minute or two
Now go back to the home page, go to Mount and see if it lets you mount data, cache and microSD (check mark next to it). If it does not, reboot into recovery, go to Mount and see if they are mounted now. You are probably ok at this point. If you can mount the partitions you can flash a rom, but I think you should update TWRP first.
I don't believe anyone has made a recovery flashable package for 3.0.2 so flash it in fastboot. If you are not sure how, go to the General section and check out my Beginners Guide - it's all in there.
Once that is done, when you reboot (fastboot reboot), be ready to grab the tablet. Let it buzz once, then push and hold the Volume Down button to get into fastboot again and enter recovery through the RCK icon.
You should now have TWRP 3.0.2 on there.
Now convert data to f2fs (there's another guide in General for that), then flash the rom, gapps and SuperSU.
Enjoy

@vampirefo and others who contributed, this is the best rom for this 5.0 device yet. At 8 hrs. unplugged, in deep sleep, I had 98% battery left. The interactive governor deep sleep offline bug is gone. The power disconnecting, reconnecting on charge is gone also. The only issue I have noticed, so far, is that the wifi connection logo at the top is not always showing as full or 100%. That is despite being inches from my router. Furthermore, when I use mixplorer, totalcommander or quickpic to access my photos in onedrive, sometimes it is very slow, or fails to connect. When it does connect, the thumbnails are very slow to load. In the older roms this didn't happen. For me this is a minor issue, because I have other means to access onedrive from my computer. So overall this is a great improvement over the older rom. Thanks to all for your hard work and dedication to improve this device!

I am currently running @greatbal rom on my 5.0 it's equal to this rom, I have to remove supersu manually, I hate when a rom includes root, other than that @greatbal rom runs well on my 5.0.
By the way, did you use windows or linux to install the rom?

I used windows 7. my only experience with linux, besides Android is through bootable usb drives and cds. I have tried Ubuntu this way. The other bootable drives were mostly window repair, backup, and repartitioning disks.
One note to windows users, there are MANY, UAC promts to to approve the running of the fastboot.exe. So you have to stay with the install to approve each of the many prompts. one workaround would be to go into windows settings and temporarily disable UAC. Then, of course, re-enable it later, after the install finishes. There may be a better way to do this though. Under my fastboot.exe properties, on the compatibility tab, I had it set to always run as an administrator. Maybe that is what caused the constant prompts, not sure. And since I have the device re-partitioned and the rom installed, I don't want to go back and test that theory, since I have installed and updated many apps. It was very nice that you had the re-partitioning built into the script for the install. Just as you stated earlier, be patient, the routine takes some time, the device has not locked up.
I probably wouldn't have bought the Ares 8A, if I had had this rom for my old device. It is too late to return the 8A, now. I haven't figured out how to root the new device, without potentially messing it up.

@vampirefo I hate to ask what is probably a stupid-ass question, but I'm still running Batville. Do I need to re-partition before installing this ROM? If so, it has been a long time since I partioned it for Batville so I'm not sure what the original setup was--can you help? Thanks for continuing to work on the device--we all appreciate it.

@vampirefo included a new partition table with the files. In addition, he put the re-partitioning in the fastboot_cmd.bat, so it is automatic.

Is there any benefit (e.g. speed or battery life) with this rom over batville? I'm assuming that the new one is larger.

See my info a few posts above. The issue I am having is with wifi, which I never had in any of the other roms.
I tested with a wifi testing app, and the link speed is good, however, the latency is fluctuating from the norm of 2 ms., all the way up to above 1000 ms. I'm not sure what would cause that, as my tablet is within inches of my wireless router. If anybody has any ideas, please let me know. Web browsing seems ok with Firefox and Chrome, but in apps where I access my photos stored on OneDrive, I have problems. I haven't tried any other internet apps to see if there are any issues. I can access videos with vlc, through my LAN, to my desktop computer with no problems.

From my personal experience, the biggest benefit is sound, I can listen to music on tablet without Bluetooth or headset.
The sound through the speaker is loud enough to enjoy.
As time permits, I plan on pulling the sound off of this and if possible apply it to my other roms, that lack good sound through speaker.
If all goes well, just applying sound patch to batville will be all that's needed for batville user's to get same sound quality, without the need to switch to this rom.
Batville is a great rom, just lacks good sound quality through speaker, I hope in time to be able to fix that, with a patch.

@vampirefo, This rom has been the best yet for my 5.0 Ares 8. The only problem I have had is with wifi connectivity. So I decided to start over. I re-ran the fastboot_cmd.bat again to reflash the rom. During the install phase it failed and bricked my device, my first. What did I do wrong to cause this?
I can boot into dnx mode and type fastboot devices, and it lists my Baytrail device. Fastboot flash commands fail with errors. adb commands don't work in this mode.
If I type: fastboot boot boot.img, it boots to uefi / bios access menu. I suspect I need a hub, a usb otg adapter, a keyboard and mouse to get the buttons to respond, though. Are there settings in this bio menu which will help me? Is there any way to recover from this that you know of?
In addition I can boot to an efi shell by holding down the home button and the power button. Unfortunately, your info on the wifi came after I did this blunder. I have a twrp backup, I can't get into it to reload the backup.
Any help recovering from this disaster will be greatly appreciated.
Thanks
Edit: I found this post:
https://forum.xda-developers.com/member.php?u=4821597
Not sure where to get this file: efilinux.efi. Is it the one in your esp folder or the one in the esp.zip?
Thanks
I solved this my self by following @social-design-concepts directions, then running the fastboot_cmd.bat to re-flash the system. Anybody have any ideas what may have caused this data corruption in the first place?

You want me to guess what you did wrong? No ideal, seeing it worked the first time and third time for you, and everytime for me, I would guess user error.

No, sorry, this is all I did:
I rebooted to bootloader. Then I ran your fastboot_cmd.bat. It never had errors in the command window until it was running the flash commands. Then it rebooted to the dnx window. So it didn't appear to be a user error. I am using minimal adb and fastboot. I have all of the files in that folder. I shift, right click, then choose open a command prompt here.
Instead of typing the command in windows, I dragged and dropped it in the command prompt window. I guess it will be a mystery. However, I did do a TWRP backup this time, even before flashing SuperSu and busybox.
I did use your fix for the captive portal and my internet seems to have improved, So thanks again.
Just curious, what is the: -S 200M, in the flashing system command?

I don't use minimal adb, that is a problem, you need to be system-wide.
Use system-wide method, it's a better way to use adb and fastboot. The script was designed to be ran based on system-wide access.
https://forum.xda-developers.com/showthread.php?p=48915118
-S 200M is sparse, the 200M is the size or chunk I tell it to split, this can be raised or lowered​ depending on speed of computer, I am using a Windows tablet to run the windows batch file.
My Linux could push it much faster, 500 or more, but 200 is safe, slow, and steady.

I had it set at one time in the system environmental variables, but when I redid my system I forgot to re-add it. Thanks for the link. I had seen that in the past, but it had older versions of adb and fastboot. I see now that it has been updated, so thank again.
Edit: I checked and apparently I did have Minimal ADB and Fastboot entered in the system environmental variables, which would make it system wide. I downloaded and installed your recommendation. it added an additional variable after: C:\adb.
Here may be the issue: I updated Minimal ADB and Fastboot with an installer and it appears it added an additional entry for it. I notice to that windows live has two entries also:
C:\Program Files\Mozilla Firefox;C:\Windows\System32;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Minimal ADB and Fastboot;C:\Program Files (x86)\Windows Live\Shared; C:\Program Files (x86)\Minimal ADB and Fastboot;C:\adb.
I think I should remove the double entries?
Here is a link for a microsoft script the remove duplicate path variables:
https://gallery.technet.microsoft.com/scriptcenter/How-to-check-for-duplicate-5d9dd711
I ran that script, but my entries remain the same. i'm not sure why.
I guess the simplest solution is to remove Minimal ADB and Fastboot, its variables and keep the other ADB.

This Ares 8 which originally came with 5.0 is running great since I redid it and applied your wifi fixes to it.
I find myself using it most of the time, over the new Ares 8A, because I have root on it and don't possess enough knowledge to feel safe in trying to root the Ares 8A, or building a working TWRP for it.
By the way, I had 98% battery left after leaving it overnight. That is a far cry from what I had with the 701Q and Batville roms. That is great.
With Batville I could never get contacts to work, despite trying playstore and other fixes. In addition, the sound is good with this new rom.
I don't do much gaming anymore, but i do have GT Racing 2 installed on the External microSD card, Using @vickybonick Apps2SD, and this graphic intensive game runs very well on it.
Thanks again for your great work.
By the way, in the past with the original 5.0 rom, I tried using three different SanDisk high speed UHS-1, Class 10 cards with Apps2SD, and all of them had good write speeds, but poor read speeds. I finally returned those cards and went with the Samsung EVO series. The read and write speeds are great on this card. I used several test apps, both on Windows and Android, to test them. Has anybody else had similar experiences with different brands of high speed cards?

If you have more than one adb install listed in the environmental variables, the first listed takes precedence in system wide access. I tested this by changing the order with Rapid Environment Editor. I viewed which one was running in Process Explorer.
Rapid Environment Editor will also show any invalid paths. This is of academic interest, as the simplest solution, is of course, to only have one adb installed system wide. If you run a command prompt from the folder where each adb is installed, that one will run, instead of the one installed system wide, unless you are already in the folder where the system wide is installed. (shift right click, choose open command prompt here).
That is what I did and should have worked fine, it always has before. So I am "beating a dead horse to death", in the pursuit of knowledge. i hope this helps someone else as well, that is learning, like me. By the way, is this considered OT?

I hate to be a thorn in your side, but:
Apparently I spoke too soon about the wifi connection working better. And please keep in mind I am comparing it to what I had on all three previous roms: the original 5.0, i708q and the Batville roms, and my newer Ares 8A. Also please keep in mind that the device is less than 2ft. from my wireless router in my tests.Using WiFi Network Analyzer, I see a continual fluctuation in the dBm signal strength, all the way from the normal -34, all the way up to the -70 to -92 range. In addition, the latency goes from normal 3-4 ms., all the way into the hundreds and even thousands ms. The older roms did not do this in the analyzer. My new Ares 8A remains in the -32-42 dBm signal strenth, and the latency stays in the 3-4ms range.
I seem to have improved things slightly by changing the following things in my router:
Allow n devices only
bandwidth set from auto 40mhz/20mhz, to 20mhz only
protected mode (not to be confused with WPS):
rotected Mode
NOTE: In most situations, best performance (throughput) is achieved with Protected Mode OFF. If you are operating in an environment with HEAVY 802.11b traffic or interference, best performance may be achieved with Protected Mode ON.
(I'm not certain if protected mode helped, or not.)
Is there anything I can do on the tablet to improve this or troublshoot it?
Furthermore are the system wifi files in the newer rom different to what was in the working i708q and Batville roms? Sometimes, turning off wifi and turning it back on helps for a while. Also I forgot to point out that the fan shaped wifi connection symbol fluctuates from full to partial, also. All other devices I have turned on to test, show no problems, that I can tell.
I haven't ruled out interference as I live in an apartment complex where I can see several neighbors on all non-overlapping channels 1, 6 and 11. However the older roms, the new 8A and other tested devices have no detectable problems with my wireless router. Does anybody have any suggestions?
Like I've said in the past this is a great rom for this device, if I can get this problem resolved.
Thanks

For my wireless configuation and router, I was able to improve my speed and connection by reading linux documentation on the hostapd.
I edited the hostapd.conf located in system/etc/wifi, changing the following entries:
preamble=0
dissoc_low_ack=0
I'm not sure, but maybe my wireless router doesn't handle the default settings as well?
If that was the case, though, why did the same defaults work well with the previous roms?
preamble=0 "Set optional use of short preamble."
0 sets a long preamble instead of a short one
dissoc_low=0 "Disassociate stations based on excessive transmission failures or other indications of connection loss. This depends on the driver capabilities and may not be available with all drivers."
0 turns this off.
My congested wireless environment may be partially to blame for this. there are at least 4 clients on each of the three non-overlapping channels of 1,6 and 11, respectively.
If anybody has any additional thoughts on this, let us all know.
Thanks
UPDATE: apparently, the above changes didn't help. In the terminal when I type: busybox ifconfig, I see dropped packets under p2p and wlan0 for rx, but not for tx. This has happened on other wireless networks as well. Maybe not as bad though. I'm not 100% sure though as I haven't run ifconfig on those other networks.
I am considering ordering an ASUS 3-In-1 Wireless Router (RT-N12), or an Asus RT-N12 D1 Wireless Router - IEEE 802.11n RT-N12/D1, to see if this improves things. I have no AC devices, so an AC router seems like a pricey overkill for me. However an AC might be more future proof. I don't have a new flat screen tv to stream to. I have an old Sony 36" CRT, which I haven't turned on for over a year, as I watch streamed TV shows on the internet, from my computer. So finally, the bandwidth that AC affords, doesn't seem necessary.

Well, I managed to (sort of) kill my Ares 8. I already had 5.1 installed and working an thought, "I'll run this and start fresh." Everything looked like it went normally but when the tablet rebooted, I have:

@social-design-concepts, thanks for this post. When I tried to reinstall vampirefo's latest 5.1.1 rom, ported to work on the 5.0 device, it failed and Could only get into dnx mode. I used your instruction to fix the ESP partition, then reinstalled the rom, with no problems. It is running great now.
Thanks, again."
I used the above commands and files within the rom posted above, so I didn't even need a usb otg adapter to do it. I believe I used the droidboot.img and efilinux.efi. The efilinux.efi is in the esp.zip. unzip to the root of your folder where you have adb and fastboot installed. The rom files must also be unzipped to that location.
The above commands are run through an adb and fastboot command prompt, from your computer. Those are the windows commands. they would be slightly different if you are on linux. Then I rebooted the tablet back into fastboot mode: fastboot reboot bootloader, which worked again, ran the fastboot_cmd.bat to reflash the rom again. This was all done from the computer with an adb and command prompt, using fastboot commands, of course. Type fastboot devices, to make sure your device is showing up, before proceeding
I never figured out the cause of the problem when I reflashed this rom the second time, but I suspect I should have done a factory reset before doing it. It was flashing the above files that gave me the ability to get into fastboot bootloader again, then I reflashed the whole rom the third time and it worked as it did the first time I did it.
Currently I am using the newer, twrp 3.1 recovery he posted in the ares 8 5.1 problems thread.
UPDATE: if you don't have a permanent recovery installed, this may or may not work in the tethered, temp, twrp recovery. I don't know as I have never used the tethered, temp, recovery.
Actually, I think I used the fastboot commands in dnx mode to flash the droidboot.img and efilinux.efi, rebooted into the bootloader: fastboot reboot bootloader and then ran the fastboot_cmd.bat to reflash the rom.
And of course, you have to make sure adb and fastboot drivers are setup correctly and recognizing your device, for all of the above to work. I tried to retrace my steps. I hope I didn't forget any of them!
Good Luck!

What is this "calypso a318uu"

Well I bought this Calypso U318AA from a friend for cheap. It was his sons he got new phone. I bought it to root it. I was just going to do the magical root.. I've rooted several other phones in past. The world wide web has very little info well, no info on this thing. It's a Android 10. I'm not sure of even the best way to unlock the bootloader. I know it doesn't have nothing in developers options. On recovery reboot you can do a recovery boot and a fastboot as well as normal boot. Can't find anything but factory at&t stuff. So any info would be great. Thank you

!. Bootloader must be unlocked.
AT&T removed the enable OEM unlock from developer menu, but there is an excellent work around 'tool' to get around this.
MTK CLIENT will allow you to read (pull) stock firmware off from phone, much like spflash tool does, except with this phone and many other newer phones the manufacture has enabled security and authorization files to block sp flash tool , SOOOO, tools like mtk client try to stay a step ahead.
I only used the GUI options with the client, it was very user friendly , the tool has way more options than i needed to mess with.

2. Before flashing gsi, make sure you have pulled firmware from phone, so you have stock super.img. If you don't you will not be able to restore device when / if you mess up the vendor partition.
3. I disabled vbmeta verification .
will need stock vbmeta from pulled firmware.
boot into bootloader, (adb reboot bootloader , or reboot while holding the volume up button. You should get a boot menu)
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
(the last part need to point to you file location where ever it is)
4. Now we need to move from bootloader to fastboot. fastboot reboot command didn't work for me so needed to boot recovery first, then fastboot.
Code:
fastboot reboot
hold volume up button to get boot menu, select recovery
from recovery select reboot fastboot
in the fastbootd connection you will be able to flash gsi
the system area is not large enough to fit gsi , so you will need to remove the /product partition.
Code:
fastboot delete-logical-partition product
fastboot flash system system-squeak-arm32_binder64-ab-vndklite-vanilla.img
once completed use the screen menu to reboot back to recovery and perform factory reset.
With the exception of needing to use mtk client, the rest of these steps are standard android process. documented in many locations. I go to the android source first for information. \

Thanks a lot mrmazak, I'm working on a step by step guide for newbies like me to expand on your steps to unblock and reflash the phone.
I was able to use MRK Client, unlock bootloader and put the phone in fastboot.
The problem I have is to find the right MediaTek driver for the device USB\VID_0E8D&PID_201C
Where did you find them? I tried Google USB driver from ADP but they use different Device ID and all MediaTek driver with same VendorID 08ED have old ProductID instead of 201C.
Any help on MediaTek driver so I can finish the guide and post the link here?
Specifically, I was able to connect via ADB but Fastboot requires a different driver which I'm not able to find
Thanks a lot for your help!

I was able to use MRK Client, unlock bootloader and put the phone in fastboot.
The problem I have is to find the right MediaTek driver for the device USB\VID_0E8D&PID_201C
Where did you find them? I tried Google USB driver from ADP but they use different Device ID and all MediaTek driver with same VendorID 08ED have old ProductID instead of 201C.
Any help on MediaTek driver so I can finish the guide and post the link here?
Specifically, I was able to connect via ADB but Fastboot requires a different driver which I'm not able to find
Thanks a lot for your help!

Yes, I had Other \ Android device listed in Device Manager, so I tried disable signed driver and force install of these drivers: https://forum.xda-developers.com/t/...32-64-bit-driver-install-tutorial-m2.3267033/
Now, I have it visible as MediaTek PreLoader USB VCOM Port but if I type "fastboot devices" is not listed.
ADB is able to see it correctly:
adb devices
List of devices attached
AYMB5PKZCUEUUOSC device
When I restart in fastboot with "adb reboot bootloader" the phone restart correctly in fastboot.
I'm not able to unblock the connection between fastboot tool and phone in fastboot mode, I suspect due to missing / wrong driver.
If you have any idea, it would be great!

Found the correct driver. I needed to force Google ADB Driver -> "Android Bootloader Interface" and it works!
They are available here: https://developer.android.com/studio/run/win-usb
Thanks for the help and sorry for confusion, newbie questions

Mod Edit: Quote removed since post deleted.
I received 'not enough space" error when flashed gsi, this is why i delete product partition.
I recall there are fastboot commands to list super.img size, but not sure for super sub-partiton size. there are tools to extract the sub-partitons and it will show individual size.
there must be commands for it in fastboot i think, But i do not know them.\

They deleted the previous post, so I'm copy paste the steps from the blog post.
Pre-requirements​
Tested on Windows 11, it should work on any previous Windows versions

hi! hope i can get some help. this is my first time using mtkclient but i can't seem to get it to detect the phone. i'm making sure to follow the steps listed of having the phone off first, then press both volume buttons and plug in the usb. on the phone it eventually pulls up a "select boot mode" where i can use the volume buttons to select recovery mode fastboot mode or normal mode boot. i've tried recovery and fast boot modes as well as just leaving it on that select screen but nothing is detected in mtkclient
thanks!

New to the world of droid but am familiar with modding stuff so I'm a semi-noob I suppose. Found myself getting one of these things from the local dollar general and followed this guide to get rid of all the google crap and hopefully speed it up a bit. Bootloader is unlocked, .img posted above is flashed, and it boots up and seemingly works. Can't figure out how to sideload apps nor can I find any type of write up explaining what to do with the tree and dump file posted above. Any help and/or clarification, greatly appreciated. MTKClient, ADB, and Fastboot are all installed and functional. Using Linux Manjaro.

Run mtkclient. With the phone already off, hold down both volume buttons and connect the phone to your computer. You should hear the "usb connected" notification sound on your computer and mtkclient will pick up it. As soon as you hear that chime, release the buttons, set the phone down, and don't touch it. The screen shouldn't come on during this step.
Make sure you're ONLY holding down the volume buttons and plugging it in. Don't touch the power button.
If you're still having issues with it not picking up your phone, go through the standard troubleshooting steps: Recheck you followed every step, restart your computer, try other USB ports, try other cables.
*********
FYI this isn't applicable to this process, but should be noted: This phone has a weird way to get into the recovery menu. You have to hold Vol+ and Power, then select Recovery from the menu, THEN immediately press and hold the Vol+ (or Vol- I don't recall at the moment) and Power buttons again until the recovery menu comes up

i was able to get all the way through up to flashing the new rom. I'm getting this error:

still can't get past this error. i've confirmed my filename, file extensions, and file location. even checked file permissions. the img file is in the same folder as the fastboot command itself.
i also tried the command using the full c:\ path to the img file but it fails the same.
i then restored the phone to the original super.bin and the phone worked like normal. so i went all the way back through the steps starting from the top but failed at the same final step flashing the system.

What are you trying to do? What is the purpose or end result you're hoping to achieve?
I ask because this thread is a bit convoluted and "noobs" looking to just root and tinker might come in thinking they have to do all the steps in this thread to get there.
Like someone wanting an oil change overhearing two mechanics rebuilding a transmission, taking notes, especially where they mentioned "oil," then walking away thinking that's what they need to do.
The tools linked above are great. The mtk one, once I was able to get it running, was how I got past the FRP. For anyone wondering, there's an FRP partition that you can just delete with the tool.
If you're just wanting root, see above for unlocking the bootloader, then stop. I'm 90% certain I achieved root by just following the process outlined the official Magisk page on GitHub.
Can I get some OP/MOD thoughts on breaking this thread up into specific guides with the purpose clearly written in the title?

I understand your questioning. I'm trying to unlock and load aosp firmware, or frankly, anything other than what this device is loaded with since it's horribly bloated, slow and periodically unstable. this is a play phone, i have two of these phones actually.

So is mine. I agree with the bloat, which I thought was weird considering the Android 10 version it comes with (Go) is supposed to be a more streamlined version for lower end phones that lack the processing power.
I tend to not do new ROMs unless it's something with a track record and support like Lineage, but after playing around with it and testing some of the functions with things like WIGL, Termux, LSposed, etc, I'm thinking it might be a good Nethunter phone.

After some extensive Googling, and since I doubt this falls under the "you're flashing the wrong build/version" because there's only one variant of this phone, I'd say it might be possible you're not running the right SDK platform package.
Start Android Studio, go to Settings > Appearance & Behavior > System Settings > Android SDK and make sure you have the right platform packages installed (i.e. Android 10, API 29) and updated.
