[Q] Stuck in recovery, no OS, unable to put files for a ROM [RESOLVED]

Okay, so I've had the issue with CWM 5.8.3.4
And unfortunately I didn't fix the the boot issue and the problem I'm running into now is that I have super wiped my internal space so I have no roms to flash back to.
I can't cold boot into an OS because there is Android OS installed on it right now.
I don't know how to place anything onto the Asus TF101 internal memory.
The clockwork mod doesn't detect my external micro sd card either.
My device is a SBK1, B40
Anyone have any ideas on how I can access my microsd from recovery? or how I can get adb working.
I tried booting into APX mode, but that doesn't seem to be working either (Vol up + Power)
Not sure what to really do now.. Stumped that I'm stuck on recovery mode with no way to access its storage.
Thanks
EDIT - RESOLVED (taken from my last post) 10-07-12
Hey All,
I wanted to update this thread, I just got it fixed tonight and it was the cable.. One of those difficult to realize and pinpoint for troubleshooting..
But if anyone ever has problems with their computer not detecting their device, it can be the cable (which in my case it was)
I was able to get APX mode working, and adb via recovery working as well with the new cable.
Thanks for all the help!

I would clear Dalvik Cache, then retrying.
and your microsd cant be seen or you cant load stuff from it?

use Easyflasher to flash a different recovery to your tablet that supports external sd card reading, like the twrp option in easyflasher

The problem is that I'm not sure how to get Easyflasher working since I'm having trouble connecting the tablet into APX mode.
I plug in the tablet and power it off, and after powering it off I try to get into APX mode, vol up and power.
But my computer doesn't detect anything. To me it seems like it doesn't get into APX mode.
Not sure how to really connect with Easyflasher..

Probably a silly comment... but every time I have used APX I have done it this way:
1. Unplug
2. Power off
3. Plug
4. Vol Up + Power
I have tried inverting 3 and 4 and it also worked. But I always start with th TF unplugged and powered off.
Probably it is the same, but maybe you can try. Have you tried another uSD?

Easy flash will work... unplug, power off, press vol up+power for at least 5 sec then plug it in.... comp should detect APX device... look up YouTube videos... there must be some kind of video abt easy flash or apex mode....
Sent from my Transformer using xda app-developers app

What I remember I tried was:
1. Powered Off and unplugged
2. If I plug it into the usb drive, the device starts booting up
3. Unsuccessful with APX
Another method:
1. Powered Off while plugged
2. Held Vol up + Power
3. Nothing happened
I'll try again and report back tonight. I'll try another uSD, but I think this recovery doesn't detect any uSD's unfortunately
Thanks

Remember in apex mode or tablet won't turn on... but laptop should detect apex mode, if not laptop should say unknown device or unable install drivers...

I don't know whats wrong..
At this point I considered my tablet bricked and cursed with ClockworkMod Recovery v5.8.3.4
I tried 3 different computers and none of them detect my tf101, they don't detect it as an unknown device, don't detect it as APX
I've tried running APX mode several times, with different ways of holding VOL UP + Power as well.
It refuses to go into APX mode unless I'm still lacking the magic touch.
I can get into cold boot mode, but there isn't an internal OS to boot into. If only I could do that as well to put things onto the internal memory.
At this point I might try to RMA.. but probably out of warranty and voided it with rooting recovery on it as well..
Damn bricked!...
Just don't understand why APX mode won't work..

If you have the keyboard dock you might want to try to use an external usb stick, you can mount it with clockworkmod

I answered your question here - http://forum.xda-developers.com/showthread.php?p=32277020#post32277020
Yes, you need to get into APX mode. And yes, it will work. You can't wipe APX mode off your tablet, it's stored in the first few blocks of your emmc, in fact it's so hidden the device uses the secondary partition table instead of the primary, so nothing can touch the partition containing APX code
On whatever computer you're using, open device manager. I'll assume you know how to get there (right click on my computer>properties>device manager) This will let you see any new device pop up clearly
Like everyone said, you just need to hold down up, and power. It doesn't matter if your usb cable is plugged in first or not. If it makes you feel any better just leave it plugged in. When my original transformer was messed up so bad I couldn't turn it off, and it just kept bootlooping, I forced it to boot into APX mode by just holding down power and vol up for a good 45 seconds, until the screen was black. It would keep retarting a few times, but eventually the screen went black, and that's how you know you're in apx. I then plugged in the usb cable
You should see something pop up in device manager - if nothing does, it's possible it's already installed a proper driver - do you see something like "apx transformer" at the top of device manager? if so, you're ready to open easyflasher.
if you hold down power and vol up, and the screen is black, and the device doesn't boot up, then you're in APX mode. Now just work on getting your pc to see it. Try right clicking in device manager and hitting refresh
Edit: make sure to do this without the dock! Use the tablet only, no other accessories
There's absolutely no reason to RMA your tablet, it's perfectly fine. You flashing a recovery didn't do any damage or alter APX mode. Worst case scenario and you still can't get into apx mode (it's easy just keep trying it). What you can do is boot into your recovery, then connect it to your computer. Then you can use ADB to push a different recovery zip (like raymanfx's hybrid cwm, which can read from external and internal) to your external sd card in the device, and mount it as /data so your recovery can see it, then use your current recovery to flash it. then you have a recovery that can read from sd cards. A quick guide here - http://forum.xda-developers.com/showpost.php?p=24793571&postcount=25
Instead of pushing over superwipe like he says, push over the cwm hybrid zip. Put it in the same folder as the adb.exe . If you've never used adb before, it's incredibly easy. Just google it.
Trust me, you're tablet is far from RMA status. My first transformer has bad blocks in the internal memory that I'm working on partitioning around using command line parted via a recovery shell, if people can do that then you can easily fix yours

Thanks for the reply, I'll note what I left in the ROM thread and post it here as well.
I've tried 3 different computers and my tablet never shows up under device manager. Nothing new pops up on the bottom right of my screen. I've tried it on a fresh install of windows as well.
Could it be my cable? Or my tablet is really broken with its usb connection. At this point I would ship it to someone on xda to fix it for me!

I've been flashing custom roms, via recovery etc since the g1, it's just strange to me that the computer has no detection of my device at all. And that I've tried 3 different computers as well.
When I get back home, I will hold Vol Up + Power in a dark room for at least 1 minute to see if I can get APX Mode.
For the ADB push while recovery mode is on, my computer doesn't detect that either (I've tried on other computers as well, one which was a recently fresh install of windows).
I'll update later today again.
Thanks

Tried the unbrick threads? I'm not allowed to link yet but one of them saved me and allowed me to do a factory reset/nvflash of official firmware.

It's not seeing an ADB device either? Dude, it honestly sounds like you have a bad cable. Especially if you've tried on multiple computers

[Q] Cant enter apx mode, cant usb debug, cant mount sdcard, cant update sdcard.

I had an old flash and wanted to update. I was going to update to Nightlies. Couldn't go into usb debugging. Chose zip from sdcard and it says can't mount /sdcard/. Tried to apply /sdcard/update.zip and cant mount and aborts. I decided after rt wants me to enter APX mode (which is volume up and power) nothing. My finger is cramped now from holding for so long. "What do I do wid these keeds," says Cartman. If I could just get APX mode to work, I was going to flash updated Asus Firmware and start over.........help?

From my understanding of APX mode:
Step 1:
Install the naked drivers (IDK where to find them, however they are in this forum)
Step 2:
Connect your USB cable
Step 3:
Press power and volume up.
Step 4:
Wait for USB connection tone from windows
Step 5:
Profit

Weird, that should have worked. your unit should already be off. then use the button combo to power up into APX mode. the screen stays off in APX mode. the only way you know it is in APX mode is when the windows PC detects it plugged in as a USB device. am i reading correctly? you are saying that pushing the button combo will not power up the unit in APX mode?

Yup! I hear the sound on the computer suggesting it went into the APX mode, but screen is still off. If I remember correctly, isnt there suppose to be a screen for APX mode? Even if there isnt, I tried to follow through with the program to change it and it is if it never went into the mode.

I did APX mode before on my droid 2, and the screen never came on. It just stayed black. Got the connection sound and then did a push to my device. I had a bad upgrade while I was in Iraq/Kuwait over WiFi for the phone. It killed the CDMA portion of the phone. I didn't know because I only used the WiFi at the time. Anyways, to make a long story short. There are some commands you can use to see if you can communicate with your device via APX mode. I think there is a shell program out there that will run in Command Prompt. You can issue commands to make sure your device is recognized via APX.

Super bricked

I hope I can save it but after 4 hours of trying and reading I can't seem to do it.
I was running an unlocked tf300 with cleanrom. I wanted to update to the newest version of cleanrom and have my tablet on that and ready for school for next term. I downloaded cleanrom on laptop and put it on my micro sd. Went and grabbed the tablet and tried using rom manager to install from sd and backup the os that was on it. Didn't work. So booted into the fastboot spot (vol down and power) and decided i should wipe data since i was there. Went over to that and pushed vol up (once). Let it sit for like 45 minutes and was still on the same screen. Thought to myself well it must be done. Shut off the tablet to restart it.
This is where the problem came up. Now i'm stuck on asus logo. The VD+P doesn't do anything but reboot into the asus logo. The VU+P will put it into a black screen and windows sees it as Asus transformer Prime APX interface. But adb can't see the device. Just device manager. typing fastboot -i 0x0b05 thing just says <waiting for device>
Every post i've read seems to tell people to just push VD+P but if i could do that and get to recovery i wouldn't be doing this. I can't put a blob file into the root sd of the tablet because I can't see the tablet.
Any help would be greatly appreciated.

Maybe this link can help.
http://forum.xda-developers.com/showthread.php?t=2034866

Device manager already sees it as transformer prime apx thing though. So i assume by getting it into APX mode doing the VU+P method it is in apx? or is that not mean it's actually in apx?

Apx mode is not going to do you any good. The previous link also provides info on blootloader " recovery " mode.
Try the universal naked drivers from this link and try fastboot again.

If that does not work leave off ' -i 0x0b05 ' in fastboot -i 0x0b05 command and try again.

I know you previously said you couldn't get into recovery-bootloader menu but that is what we have to accomplish. Apx mode on this unit is only good if you previously installed nvflash and had all of the proper backup files.
The first link I provided provides 9 ways to get into bootloader menu and from there either fastboot mode (usb symbol) or recovery (RCK). I know some may not work but we only need one.

apx or bootloader menu-recovery.
To use this guide to enter the bootloader menu just use volume down everywhere it says volume up. Everything else is the same.
4. with unit powered on hold volume down and press reset with paperclip - (don't press hard) reset is located about 25mm or 1in below the sdcard
try this one.

Force power off by holding power a few seconds.
Plug power cord into tab with the other end of the power cord not plugged into anything. Hold volume down and plug other end of power cord into pc. This done without pressing power again after it is powered off. Easier to do than describe.

The Problem lies in holding the volume down button. No matter how i turn it on. either plugging it in while holding power down, reset button, letting it die and then plugging it in and turning it on....it just goes into the asus logo screen .

I'm sorry, I did understand that from the beginning but the only things that can save you is get into that menu or recovery or your tab accepts a fastboot or adb command. That is the reason you keep getting pushed into that direction.
My best guesses are out. Sometimes redoing something you have already done twice works.
My experience and all I have read rom manager has issues on this tab. Also many who wiped data from the bootloader- recovery menu reach this same point when they reboot.
Some have recovered by just doing each thing again and again and suddenly something works.

Yeah i fear i'm just going to have to call ASUS . sad panda. i keep trying different methods of doing the VD+P method but it just won't get into recovery.

I'm sorry but I am afraid you are correct. If unable to use adb, fastboot, or get into recovery there aren't any other options. Sorry if I pushed more than I should but I wanted to see a more positive result than calling Asus.

If you explain you were having issues with your tab and used wipe data hoping to correct the problem. Now when you turn on it just stays on the asus logo maybe they will repair it without cost.
If you go into detail you probably won't get lucky.

[Q] Completely bricked TF101

So I was doing something on my tablet, and it shut down.
I tried to reboot it and it was stuck.
I thought i had my rom on it (KatKiss) so i did a factory reset and tried to flash it but then i saw i deleted it when i flashed it at first.
So i thought ill just use EasyFlasher and get it back up and running.
Then I tried to get into APX mode and failed.
Volup + Power = Nothing
It just powers on the tablet and it stays there at the Asus logo.
I tried to hold it for 20+ seconds, nothing.
USB is plugged into the tablet, not the dock.
Tried to use sdcard to flash rom on it, cwm cant mount sdcards...
So if anyone could help it would be great

CWM bricked your tablet most likely - you should be running TWRP Recovery for KatKiss ROMs
You need to get the tablet into APX and get EasyFlasher working - APX should still work, nothing appears on the TF screen in APX mode, only way you know it is working is USB connect sound / device connected notification on PC

Keep in mind - APX is a black screen. The only way to know you are in APX is to see if a PC detects an APX device.

I know APX is just a black screen, but even if i try to do it while usb is plugged in it just reboots to Asus logo.

You sure your volume up button is working ok ?
Try removing the plastic bezel around the edge of the tablet and press the actual micro-buttons under the silver ones you normally press

Make sure you have the correct drivers for APX mode. I got mine from x3maniac's Tubuntu - One Click Installer for Windows
From this thread
http://forum.xda-developers.com/showthread.php?t=1995157
In the package, there are the drivers and also a flashing program(NVFlash). You can also use this. Even have a APX mode detected status at the top so you don't have to do the guessing work that it's in APX or not.
P/s: Just to confirm, to go into APX mode 1) Turn on your tablet(not necessary to wait till it boots) 2) Hold the power and volume up button until it shuts down and keep holding the buttons until you see it is detected as APX mode on your computer.

APX mode is from a powered off state:
Hold Volume Up & Power until PC recognises it
Done

unplug and boot apx
I usually boot apx and then plug in the usb shortly after. Also note that occasionally a grounding issue occurs (happens with my bull**** Dell Venue). Run a piece of metal across the usb pins while the tablet is off and try again after ensuring the device is charged.

[Q] Shield Tablet stuck in APX mode - Black Screen - no bootloader

Good day everyone, here is my issue.
I bought the nVidia Shield WiFi 16G and didn't do any modification to it at all (original bootloader, straight out the box)
I tried to do the OTA updates and it kept freezing at the nvidia logo.
Force shut down and bootloader to Recovery mode.
The update 1.2.1 installed when it started to boot (little android guy with the thing spinning in his chest).
Update 2.1 same issue.
I repeat the steps. Everything seemed fine as well, the loading bar finished.
Then the screen went black... pressing any button doesn't do anything. So I decide to plug it in my PC.
It says APX Driver can't be found (recognized that way by PC)
Screen is black
Cannot get in bootloader by pressing power & volume-.
I can turn on/off the tablet (I get the sound that it disconnect from my PC) by holding power button down.
Then pressing power & volume+ together, it connects again. Still Black screen.
I read a bunch of forum about the NVflash and nothing seems to work, all the process require me to go in Bootloader which I cannot access.
I am able to install drivers for the tablet to be recognized, but there is so many of them that I am not even sure they are the right one.
When I try the NVflash solutions, my command prompt says "fastboot" unrecognized command.
Nothing is working.... I need help
Thank you in advance

Ok so I have installed Fastbood and Minimal ADB.
For some reason, the NVidia website wants me to register as a Dev now to download the image of my tablet...
Anywhere I could find the image to nvflash ?
I am downloading the Linux version right now, 2.2Gb, will that be alright ? I am running Windows 7
Oh and the command prompt keep saying error: device not found when I type: adb reboot bootloader
This is frustrating....

If you're not getting passed the bootloader, you're not getting adb access. Booting up by holding power and volume will get you in bootloader mode and fastboot should work.

There is no bootloader for me.
Power button does nothing.
Power & volume down does nothing (no bootloader comes up, it was doing it the first time I got the tablet)
Power & volume up (while connected to PC) will connect to the computer as APX.
Holding power once in APX mode disconnect from the PC.
Those are the only thing happening with the tablet.
Black screen lol

Sounds to me like you've got two options. Either a) Get the apx driver for windows, get it in apx mode and run nvflash. Or b) contact nvidia and get it swapped out.

I had a similar experience with another device. It shipped slightly damaged and when I tried to update it locked me out of my phone. Had to rma it....

Well it seems to be in APX mode already.
I tried different drivers, but having the right one would help me out a bunch (I have the Shield tablet WIFI 16G)
not sure how to run nvflash. Everywhere I look they ask to access to the bootloader, which I don't have access to. And I am not sure where to get it, I found different version on different website.
A bit of help would help tons!

Did you ever get this figured out, it would appear I'm now in the same boat.

I too fell to the dark side and aquired this problem. You intelligent people, please solve it for me. I cant find any APX-drivers out there.

Yep my first shield did the same thing and I had to send it back because I couldn't figure out any way to get to bootloader nor fastboot, just a black screen.
My second shield had blown speakers due to that 3.0 update failure and finally the latest update works good with my 3rd tablet, thankfully I don't have the battery recall.

All these problems you are all facing is the killswitch made by Nvidia for the recalled tablets. They render them unusable so you are forced to return/dispose of.
So far, there is no way to fix them, being necessary a special driver that only Nvidia has.

Hi I have a Shield Tablet killed by NVidia. Working on it, I created APX drivers to make this tablet recognized by Windows. I don't know if drivers work really as I wish... I created them basing on Universal Driver Naked (APX Version). But the only thing is that any nvflash tool that I tried doesn't work and one gave me error 0x30011 (I think it is device not connected). So this work is so hard...

Shield
Hi, same since 1st september, black screen+APX forever. I'm on Linux with nvflash version from Transformer LinuxTools.
Usually no need of drivers on linux so I give it a try. With '-r' stay on [resume mode] message, '--go' Error 0x8 and '-bl bootloader.img' Unknown device. Where did you find your nvflash version ? maybe mine is wrong or too old.
But what is fun is when I disconnect the Shield, I have a greetings from nvflash command line so Shield is alive...
Last thing I did with was playing with DS4/PS4 controller wired on usb by an app bought on store. Not rooted so I'm confuse but the Shield was plugged in charge since a week maybe the mistake. So I try to manually update/boot through APX, no way with pwr & buttons.

I found them googling and I tried tegra3 and 5.1.x (that I understood it is for GPU NVidia). So I haven't tried right version i think... I don't know even which one are good for me I'll see on linux what happens (if I can install it)

TDP 3.0r3/4 have nvflash and APX drivers (and I'd assume the Jetson TK1 OS images have them too). but, as repeatedly mentioned on these forums, these are all useless without the SBK that is unique to each device, and that only Nvidia knows

@Bogdacutu
can you dump a copy of the bootloader and post it?
