[Q] The Device is unlocked Message and stuck at ASUS logo

Hi all,
I have an ASUS TF300T.
A friend of mine tried to root it and install a new rom. He said he followed steps that he found on XDA and was trying to flash a new JB rom.
Having said that, now the tablet is stuck at the ASUS Logo during boot and there is a message on the top left "the Device is UnLocked"
Nothing happens!!
I tried holding POWER + Low Volume button and it does not get into bootloader. ADB and Fastboot does not detect the device. Even Windows and Linux do not detect the device.
So i tried POWER + increse Volume button and it gets into APX mode. I used the Universal Naked Drivers on this site and windows detects the device.
But the question is how do i restore it or how to reformat it ...etc.
Is there a way to use External SD card to get help in this situation.
Can anything be done from the APX Interface ?
These are the links that my friend has followed ...

Thank you all for your help !

[Q] Padfone 2 bricked: invalid kernel

After a lot of reading on Xda and Modaco I am still not much further.
After rooting with Framaroot and installing TWRP through Goomanager I bricked my phone because I forgot to unlock the bootloader....
Is there any hope for this phone?
The phone cannot get into fastboot: power button + volume up.
Recovery menu (power button + volume down) is non-functional > I get the "invalid kernel" message again.
ADB and Fastboot and cmd in Windows are all very new to me but I have nothing to loose.
Thanks in advance for any advice.

"invalid kernel !!!" - I bricked my phone
Hello,
I have exactly the same problem... I've also red a lot without finding any suitable solution...
I rooted with Framaroot, installed TWRP and thats it - I bricked my phone (probably because I forgot to unlock the bootloader?)....
Same problem for me: the phone won't get into fastboot (Power+VolUp).
Recovery menu (Power+VolDown) doesn't work: I always get "invalid kernel !!!"

Hi Vakilando,
It seems we're on our own with this problem. Either no one has an answer or all knowledgeable people never had to deal with this problem.
We also choose a not-so-popular phone. The tablet-phone combi is too expensive and the tablet of mediocre specs.
I went for the too-good-to-be-true price for the phone-only... and after a lot of reading found out that quit a few people had problems with their phone.
Perhaps some code monkey (no disrespect) could tell me if we have more options when the phone is connected to a Linux system? Android is Linux based, so that would be a compatible pair. Windows can only see one partion on a flash card and, but I might be wrong, Windows cannot read EXT 3, 4 partitions.
Windows device manager does recognize the phone as "ASUS Android Bootloader Interface" so the phone is not completely non-responsive.
I also posted on a German site; Android-Hilfe where there's a dedicated forum with knowledgeable people so perhaps that gives more options.

do this!it will work!!!

Sorry, for not well-advanced users - could you please describe step-by step how to flash phone in "invalid kernel" condition CWM recovery with fastboot? Tnanks!

Ola Goldenval, try this link, it worked for me.

This is first link I found in google & tried to follow. My problem is that PC (W7 ultimate) doesn't see the phone. So cmd window is hanging on message "waiting for device" forever. Problem isn't in PC, as I tried different PC, where another similar phone had been seen some time ago.

Hi Goldenval,
the onlything I can tell you is that it didn't work out for me the first time, just like you now. Then I found another, German, website with lots of information on the subject and I gave it another try. Second time I succeeded...
it is a long time since it happened so I can't recall all the details but keep on trying and you will succed.

[Completed] [Q] Interrupted flashing process

Hello friends,
I was using a General Mobile etab4 tablet,
rooted,
bootloader locked,
not backed up, i tried but apps wont recognize the brand,
the stock rom is not available anywhere but I managed to find some custom ones.
This tablet is actually a given by government for educational purposes, and it has no download mode, I can only initiate recovery mode with volume up+power button combo, and there is no sd card in it.
Here is what happened. It was running with problems so I decided to flash a custom rom I find on this forum. First I tried flashing using adb sideload. I got an error message "Installation aborted" with no error codes after verification step but it does not state whether verification is failed or not. I don't know what actually failed. Then I tried to flash it using adb shell as root (the system image was in /sdcard directory). It freezed, I exit the shell using Ctrl+C command. Then whenever I try to start shell i got "error:closed" message. I see my device with adb devices with sideload, but it is not seen in fastboot devices.
When I try to open it, I guess it enters in a small boot loop (screen flickers multiple times with brand name on it) and after some time I got dead android with no command written.
I tried,
reflashing it again with Android AIO Flasher,
use fastboot to unlock bootlader (it says "waiting for device") although adb devices sees it,
re-installing the adb drivers after uninstalling them,
disassembling the device to see if I can detach memory to edit it and to see if disconnecting the battery helps,
I even used a simple jig to see if i can initiate download mode (know it works for specific devices but you know hope)
Apparently, I messed up the device but the hardware must be all fine. So I think there must be a way out. What can you suggest, I wish I have unlocked the bootloader. I can send the pictures of its motheboard it helps,
Thanks in advance.

ADB Device Not Showing as Attached - Shield Tablet PLEASE HELP!!!

!!!PLEASE HELP THANK YOU!!!
Hello everyone thank for taking your time to read this and for hopefully helping me out....
It started a week ago when I had notice that when I updated my Tablet (32gb LTE UK) I forgot to redo the Supersu function and TWRP so i went ahead and rebooted my devices and installed TWRP via adb fastboot not a problem there and i got into custom recovery and install Supersu and restarted the tablet like all the other 20+ times But this time around it stayed on the boot logo and thats as far as i get.
Now having done this many time before on this and my two other shield tablets and samsung phones I'm at a loss, as now when i boot into the bootloader with the options for me to use ADB it will not find my device. I've even gone ahead a installed the rather large and normally unnecessary Android Studio with SDK Manager and tried it with the google drivers instead of the shield driver that I've re-download just in case they had been updated.
* Tablet stays on Boot logo
* I can boot into Bootloader
* If i select fastboot screen goes blank but is on
* If I select Recovery tablet boots with Android laying down as if Sick
* I no longer had a Custom recovery (TWRP)
* ADB does NOT list my attach device
Sorry if I've gone one but as you can tell I'm normally good with this kind of stuff and have looked around for a fix but all have failed so far please if someone can help me that would be the Brilliant.
Cheers Chris.

check device manager in windows while tablet is in bootloader and usb connected. look for a device called fastboot and see if it has an exclimation. Download the atteched zip and look at the images for a visual guide on what to install for the drivers.

any solution??

[Completed] How to install ROM on Vonino Pluri Q8 tablet ?

Hi there,
Today i've received this tablet. All good and dandy until it notified me it has an update so obviously i've gone and do the update. Surprise.. after reboot, update installment and so on the device won't boot anymore at all, and recover mode doesn't work to enter.
I've found official ROM package on their site:
ftp.vonino.org/public/Firmware/Vonino_Tablets/Pluri%20Q8/Orange%20Version/Android%206.0/
Tablet can connect to the PC, but it isn't recognized because "some drivers" missing. How can i install this ROM on the tablet from my pc ?
Thank you.

Hi,
I can't find anything about it on xda or anywhere. You'll need to contact the manufacturer for drivers and instructions on flashing their firmware.
Good luck!

After i tried like almost the entire day i got the tablet in rescue mode or fastboot mode..
I've wiped/data or factory reset and the same happens... it stays in a loop when boot at logo.
I've let it to do so until the battery went dead from 100% and still the same.
I have official ROM but can't install it at all. I think the bootloader is locked?! And it doesnt even unlock it when using some fastboot commands
Also can't install nothing from SD card and when tryin to use ADB the PC can't see the device, but when using fastboot I can work on it.
In rescue mode i've done some root integrity check and at the end of the check some /system files are modified. I believe this is causing the entire problem.

Typically, on devices I know of, it's fastboot that you would use to flash factory images. So you should be good there. But again, I don't know if that is how your device works too. And it would also typically not matter what's been altered on your device, system wise, you would simply flash the appropriate images with fastboot.
So I'd still say you need to determine the correct procedure to flash the files you got from their site. Perhaps there site has instructions? Or a support number for help of its not working as it should?

I've talked with the support. They gave me a link with an official ROM, a different one that the one that was from the site. But they didn't even told how to use it, LOL.
Have the damn files and don't know what to do with them, OMG.
I've placed the zip archive on SD card and tried to use the option from rescue mode with 'update via sd card". The zip archive is visible but after i select it says Installation aborted :|
I've googled around and maybe my tablet needs to be at over 50% power... but it was plugged into the wall it should've worked.
edit: 100% and no good...
edit2: they sent me another e-mail with a pdf file in which it is explained how to flash their device.
