wifi Xoom 3.1 unlocking bootloader error...

I've followed all the guides to a T. and my SDK is able to run nicely. However, once I've made contact w/ my device in 'usb debugging mode', tested the connection w/ "adb devices" in command prompt, and set the device to bootloader w/ the "adb reboot bootloader" command, and finally I give it the command to "fastboot oem unlock", I get an unknown error!! Please help. I have all the path variables set, and my SDK is running good, and has all the newest updates.
This is a link to a video I made of the problem. Please watch. It'll help if you can see the problem! just copy paste into search bar - youtube.com/watch?v=2bROUZh7GRI
Thanks for your responses. I hope they come quickly!

OK, I will first say that I'm not an expert, but have gone through this process and have had to use ADB a number of times, so
1) why did you copy all the platform tools into tools folder? It should be otherway around, but clearly you have it working, so OK with that,
2) do you have all the files you need in your tools folder (since that's what you are using)?
3) are you using the proper syntax? No additional spaces where they don't belong, and so on?
4) are you getting any messages at all on the Xoom itself when you enter these commands?
5) Review all of your steps. Start over. If no luck, why not try to chat with experts on Xoom Channel on IRC? Maybe they can help you pinpoint the problem.
It doesn't seem serious but I think you've maybe missed a step in your prep work or have something simple turned around.
Good luck.

-copied to tools folder, because that's what I was directed to do... Guess it works either way.
-I do have all the files needed.
-How do I know if I'm using proper Syntax or not? that might be where I went wrong. But idk...
-No messages AT ALL on the xoom screen. (actually, 1 time out of the hundreds of times, Below the 'fastboot' words, I got red words that said cannot process command, or something like that.)

Do you know what you did to be able to unlock? I think you really have to be careful to type commands EXACTLY as shown. No extra spaces, but don't leave anything out either. Looks like commands aren't typed in correctly. Take your time. You'll do it.

I had this error followed by "unknown partition". When I tried fastboot boot recovery.img, it would say it could not access recovery. I deleted every partition and sent the device the stock imgs. Recovery would still fail.
STRANGELY ENOUGH, I rebooted my PC, unplugged the cable from the Xoom, let the device boot, changed USB debugging to on (stock unchecked it when imaged), and it took the recovery flash that time. I can't explain why, but it worked for me.

If you haven't already. Delete the .img file. and reinstall it. try the process again.
make sure you're inputting the full command prompt from the beginning. That was my problem. Hope that helps.

KindleFire Partitions error? [Still not fixed]

When I flashed a kernel I did boot boot.img first and it worked so I did flash boot boot.img with fastboot. Well that didn't work. So I just got the other boot.img for cm7 and tryed to do that. Well I got this error:
C:\adb>fastboot flash boot boot.img
sending 'boot' (3196 KB)... OKAY [ 0.875s]
writing 'boot'... FAILED (remote: partition does not exist)
finished. total time: 0.885s
When a wipe is issued:

erasing 'userdata'... FAILED (remote: : partition doesn't exist)
finished. total time: 0.002s
I am in fastboot but I can not get into twrp2 because when I hold down the power button to enter recovery it just turns amber and just hangs. I do have some mmcblk0pXX .img's if it helps.

I think I'm having the same problem. When I try to boot the bootnew.img for intersectRaven's kernel, it hangs at the FIREFIREFIRE yellow triangle with an amber light. No fastboot commands will take me out of it. If it makes a difference, I installed the custom WiFi driver.

Thats the exact same thing is for me.

I guess we're in the same boat then. I think my problem came from booting the kernel up, then installing the custom wifi driver, then trying to boot it up again.

Did you follow precisely the commands given here? It sounds like you did, but I just wanted to make sure. I was going to suggest you reset the bootmode to 4000. Have you already tried that?

Since apparently the OP and I have the same problem, yes I tried that. The command "fastboot -i 0x1949 oem idme bootmode 4000" doesn't work for me. It just boots into fastboot again.

I read someplace when I rooted 6.2.1 with perhaps a Burrito Root prog. The recommended order to get CM7 and TWRP . Is to go - in this order. Root, then TWRP AND lastly update.zip to sdcard for install of CM7. I made space avail. for TWRP'S Backup ( STRONGLY RECOMMEND ) BACKUP. ======which saved me a few times already on a couple frozen boots. Cause I experiment with various launchers, I think.

Yes I have. It just hangs on the yellow boot with a green light.

The thing is that I cant even root it. It is just stuck it at boot screen for FIREFIREFIRE v1.0.

I suck at pushing buttons on forums now (hence the accidental thank), but I'm not really trying to install CM7.

Have you tried the hard reset? Hold power button for app. 18 seconds till screen goes totally dark, then press power bttn on again, once.

Yes I have many times.

I can suggest changing the driver on usb in pc or rebboot pc after uninstall and the change it . But I wanted to show a procedure. win utility 7 gave me the necc. usb driver v. 6 did not have.

Gotcha. Any luck with this method?

There was also A kindlefire utility v.? with an option in red for "factory reset" on the device, perhaps.

Yes I have. Can't even do adb push. When I get into adb with using boot boot.img from cm7. I get, exec /system/bin/sh' failed no file or directory.

I would not give in, but try to stay calm with all methods to reclaim functionality. I started with rootwiki and Jayce Ooi's And Burrito in order to stay clear of CMD console cause I was not even recognised till Win_usb drivers eventually fell in place. Saw some stuff about editing path's also. Reading alot helped.

Nexus 7 - Bricked, Need Help, should be fixable!!

Hello,
Got a Nexus 7 (Wi-Fi), it was running on a CM 4.2.2 custom rom, then I decided to flash the original rooted 4.3 rom + franco kernel, after then, all the problems started - it was restarting all the time, some of the apps were not working, so decided to move to CM 4.3 again. After flashing CM 4.3 (newest), I got stuck in a bootlopp with Google logo
What is working:
- I can boot into fastboot (bootloader) mode
- The device has an unlocked bootloader
- I can boot into recovery (STOCK ONE, custom one disappeared)
-PDAnet drivers installed, so I can use adb sideload function while I am in recovery (apply update using adb option) - no use probably
What is not working:
Tried toolkits, seems like fastboot drivers or mode is corrupted, when I plug the tab to the PC, it says malfunctioned or smth like that
So, what I can do to fix this?
P.S it is not under warranty

Hi, Pomperis...
Yes... fastboot flash the Jellybean 4.3 factory stock image (see my sig for download link).
Be aware though, you might have problems flashing the bootloader (v4.23).
Go here for instructions, should you encounter that problem.

Okay,
Got the stock image
Unpacked everything to platform tools folder and swapped the original bootloader image with the custom one (as advised in the thread)
When I type fastboot devices - it seems like fastboot is al right as I get:
xxxxxxxxxxxx fastboot
However, when I try the following steps:
C:\android-sdk\platform-tools>fastboot erase boot
erasing 'boot'...
FAILED (command write failed (No such device or address)
finished. total time: -0.000s
Same with other commands
Any ideas?

That's odd... you clearly have a viable fastboot connection (re: fastboot devices... by the way, for securities sake, you'd be advised not to publicly make known your unique device ID... type some random digits if you wish to illustrate your point).
What happens when you run flash-all.bat?

Great you got it sorted... it's always the same with tech; lots of sophisticated software, but often the problem just boils down to a bad USB cable connection, or as you say, some other temperamental aspect... usually hardware!

Help with rooting P8-lite Ale L21 dual-sim C432B564

I have a relatively new P8-lite L21 dual sim phone and I am quite happy with it. It came with C432B170 which is Lollipop I think 5.01. After a few days it updated to B172. I have unlocked the bootloader after registering with Huawei and waiting 2 weeks. Then I have successfuly rooted the phone with Kingroot phone version. Two or three weeks ago I have updated the phone to MM (6) and Emui 4 with local update (B560) that I have gotten from this forum. 2 days ago I recieved the notification of OTA B564 which went smoothly beside the fact that it reset the phone but i have succesfully restored (contacts, data etc.) All of this time since I upgraded to MM i have tried to root the phone but I was unsuccesful either with any software solution ( Kingroot, Kingoroot or others). After reading most if not all discussions on this forum and several blogs and how -tos, I tried the so called fastboot method others have recommended but here is now the gist of my problem. My phone is seen by my PC - OK so USB drivers are properly installed (by the way my PC is Win 10) and I have installed Android SDK as well as minimal ADB. When i try to flash TWRP 3.00.2 I can not do it (the message says something about not able to access or i think remote command not allowed. So since I cannot flash TWRP i am unable to put SU on the phone and root it. I hope someone more experienced and skillfull in Android world can point me in the right direction and help me. Thank you

Download mininal adb fastboot and then try to flash twrp via fastboot.
That error occurs because your adb doesn't have full permissions.
Minimal adb will solve this.

Downloaded minimal adb fastboot and installed it. Tried the procedure. Copied TWRP recovery to the minimal folder. Shift right clicked in the folder of minimal and opened command window. Adb rebooted to bootloader. Phone shows it is unlocked. The device is seen in fastboot window but flashing recovery doesn't work (same message) I am really confused. How do I give adb full permissions ?
Any way thanks in advance.

Try reinstalling drivers with universal adb.
Are you sure your bootloader is unlocked?
Type fastboot devices and let me know the output.

The drivers were reinstalled. My bootloader shows unlocked on bootloader (bottom of fastboot screen). Fastboot devices does nothing.

Weird... i can't think of anything else myself that hasn't been said. Perhaps... redownloading twrp? Maybe the image is corrupted by something... ot's a long shot because ot should flash everytging that comes its way. But it's the only thing you hven't tried.

Can't flash TWRP recovery on OnePlus 5

I was trying to download and flash xposed on my phone, so I got the app and downloaded the zip.
I went into Magisk and for some reason I flashed xposed framework through Magisk (I thought it might work)
I tried flashing the all 3 of Xposed installers and didn't work.
Realized I didn't boot so I re flashed the stock rom oos 4.5.8, and it worked again, but no root.
So I quickly try to flash twrp through adb on windows but it doesn't work, I keep getting an error message going like.
sending 'recovery' (27525 KB)...
FAILED (remote: Requested download size is more than max allowed
)

I haven't seen a thread or a website explaining how to fix this.
Yes i did try git bash, but the same error happened.
Please and thank you.

It seems to work best with the cable that was sent with the One+5 but you could try a different cable...

Had the same issue. Just get the latest ADB from XDA, it should work fine.
