I had rooted/cwm'd my tf101 when I first got it. It was running the 3.1 update at the time. I followed the pure root posts here on XDA.
Sadly I had never tested CWM, and perhaps since it went so easily I didn't really understand/read enough on CWM to understand what is happening. When I ran the 3.2 OTA (OK so I shouldn't have done that, I know now) the TF froze on the initial splash screen.
I've tried many things and read tons of posts here on XDA and other sites, and I'm not getting anywhere, but part of it is I don't know for sure what I'm trouble shooting.
I was using a dual boot laptop in Windows mode when I did the initial update. I had the drivers working and succesfully rooted my system.
What I am trying to do is restore a stock rom for now and I've tried several methods.
1) Asus download SOP - It detects the image on the SD card, checks validity of the firmware, shuts down and reboots and hangs at the first splash screen.
2) CWM recovery, if I understand this right, I Power+ vol_down. I hit the vol_up to enter The screen says
Checking for RCK. press key <Vol_Up> in 5 sec to enter RCK.
I do that and it hangs at:
Booting recovery kernel image
3) I've tried several nvflash posts out there. NVFlash does not seem to be working, I've now done this on two windows boxes. Both the one that used to work, and a clean windows XP machine I had lying around. In both cases, I can get the nvidia APX drivers loaded and the device is seen. However, adb doesn't show any devices, and from pulling apart the batch files and doing some reading, I tried nvflash -r --getpartitiontable myfile.txt and some other commands which always hang. Eventually if I disconnect the tablet - then I get a read error of some sort.
4) quick reboot - every option leads to reboot and freeze at first splash screen.
So questions that I can't seem to find an answer too.
1) If I'm connected in APX mode, should adb show a device? Like I said the PC recognizes it as the APX device and loads the nvidia drivers instead of the normal transformer MTP drivers when I do the power + vol_up.
2) Is there a simple test to use for nvflash? The device shows up, is there anyway I can confirm whether APX mode is working or not?
I'm only starting to piece together the boot process in my own head, and my guess is that niether the stock recovery image or the cwm recovery boot image is working. Would that be a reasonable assumption based on behavior? I will admit I really don't understand the boot loading process in android.
FYI, if I go through Power+Vol_down, wait for rck to skip and then boot without wiping, the TF is fine after that. Meaning as long as I don't try to update, it will work and reboot normally. Root also still seems to be working.
I tend not to suspect a driver issue, since one machine was confirmed working, it's how I got root - and 90% of the time that machine is run as linux. I almost never boot into windows. I'm pretty sure the last time I did was to root the TF.
What happened is you overwrote the cwm when you installed the new update. You can't just randomly install things once you're rooted.
If you have a B7O machine, you need to check that you have the old or new sbk. Go to the general transformer forum, and there's a thread about the new sbk locked bootloader. Follow the test to see if you have one that you can use nvflash with. If that is the case, then go to the dev forum, and look through the nvflash unbricking thread.
Thanks for the reply
First off, you're right and I should have known better. Almost nothing I own runs it's stock firmware, and I just got dumb and didn't do the full research excited for HC 3.2 goodness.
I have a B50 machine, or at least the my serial number indicates that.
I've already tried several nvflash debricking instructions, but it seems that nvflash is not working either. I have several copies of prime and the .11 release from asus. But since nvflash is not behaving as expected, all of those threads are not helping.
I do have the nvidia USB recovery device show up in device manager, but every nvflash command fails hangs at
nvflash started
[resume mode]
ADB devices shows a serial when I'm normally connected, but it doesn't show up when I'm in APX mode. I'm just not sure if the device is in a functional APX mode, since nothing actually runs, despite it showing up in device manager. I've tried googling that situation, but I can only find posts that tell me how to get it to show up in dev manager... It seems like when that happens everyone else has been fine.
WHILE GOOGLING FOR MORE INFO ON b70 - I managed to get NVFLASH working, and now I get what the first command and -r do.
3.2 Update Problem SOLVED
So look at the original post for the strange condition I had gotten into.
Somewhere along the line, the transformer had stopped responding to adb even not in APX mode.
I uninstalled PC Suite and Asus Sync. Then reinstalled only ASUS sync. ADB started working when TF was connected normally
I did not reboot my PC, win7 64 bit. Shutdown transformer, it hung at the splash screen. WHILE HUNG, I held power and vol_up until device manager showed nvidia USB recovery device
I used the stock rom replacement from tabletroms. Sorry I can't include the link as I am too new to XDA.
Got the transformer back up, set up my account, restored data. However OTA from there was not working.
So I went to ASUS, grabbed the .11 image and updates via SDCARD following the SOP instructions.
After reboot, checked for updates, and there was one. Let it do the OTA for 3.2 and now I'm back at having stock 3.2 updated TF.
I will probably root, but may not CMW this time.
Ok like an idiot I went to install the stock Asus rom over my AKOP rom using twrp. Now it just sits at the Asus logo screen and will not boot. How the hell do I fix that?
If you still have fastboot flash cwmand do it again
And if I don't have fastboot? I mean right now if I hold vol down and pwr all it does is turn the screen off. It will not boot into twrp

Turn the screen off? Screen shouldn't be on when you do it, shut it down, then hold Power+VolDown until it turns on and the white text comes up in the corner.
then you will see 3 icons choose the usb icon with Vol- and Proceed with Vol+. Then you are in fastboot.
I got it thanks! She's back up and running.
Hello,
I also have the problem to get stuck in the boot screen. I have a brand new TF300TG, only installed some apps (not unlocked, not rooted). I only made the automatic update to 9.4.4.40, after that it always stops at the boot screen.
What I already tried:
- cold boot
- wipe
- RCK (Android with rotating things shows up short, after that the Android with the warnings sign shows up)
I also downloaded the whole WW 9.4.4.40 package from ASUS and put it on a MicroSD. If I make RCK with this (if I rename the file to EP201_768_SDUPDATE.ZIP) the Android with the rotating thing shows up longer, but I still get stuck in the boot screen.
I already contacted ASUS support and will also return it to a service center, but I'm in China and expect a long process with some troubles, so I wanted to ask if anyone has another idea what I can try?
Ernst
Update:
I think it was now possible to update WW 9.4.4.40 again (renamed to EP201_768_SDUPDATE.ZIP). I now used a different MicroSD with only 2GB. The first time RCK it stopped in the middle of the update (after that the Android with the warning sign came), the second time I tried it, I think it finished, but the TF300TG still stops booting at the ASUS boot screen.
If I try now to update over MicroSD again, it doesn't work.
I have the same problem, only difference is that pressing vol down and power on makes no difference. When its on I also can't turn it off. I just have to wait until the battery is drained.
you have flashed ICS ROM in JB bootloader as far I see - hardbrick if you don't have nvflash files - only service.

Its not me Its the Drivers!!!
So I have a TFT300T, unlocked and rooted, all was fine till i decided to try another ROM. So I installed CWM no problem. Once I installed the ROM problem. I seem to be stuck at the ASUS screen. I have tried loading boot loader to do a wipe and factory reset and that simply boots me to CWM, tried the same thing there but to no avail. So researched bricked Transformer and came across the Nvflash method as well as the Asus Transformer Kit (US ONLY). However I cant proceed cause of the APX driver issue. I tried the included drivers but Win7 wasn't interested. I tried 1 desktop and two laptops, same thing. I even tried my bench tester. Now Universal_Naked_Driver_0.72 seems to install but no communication between the PC and the tab with this driver.
I tried bootloader to try a fastboot command but then the Device manager demands a driver for "Transformer". Same issue. Tried downloading from Asus plus a couple on the web. It seems its the Tablet. I thought to try CWM and an sdcard but it doesn't give me the option to mount it. So if any one knows a fix I would be forever grateful.

I also found the asus transformer kit(us only). But the same problem. I am able to connect my tablet with apx mode, in my device manager I see apx device. but in the tutorials it says that I have to force install de driver, but I don't know which driver to install. I tried the asus driver and every file in the asus transformer kit but nothing. I triend the universal_naked_driver but I can't get it to install can anyone tell me how to proper install that?
Ok, currently running
Unlocked bootloader using the TF300T 4.2 method.
Installed TWRP 2.5.0.0 (works great)
Running the lastest CROMi-X 5.1
Everything installed and was running ok, until I ran the encrypt android device. I started fine, then I left it for an hour and a half, came back to the device boot cycling (Was fully charged and plugged in). Since then I have tried reflashing the recovery via joelalmeidaptg’s installing TWRP recovery instructions.
Code:
fastboot -i 0x0b05 flash recovery twrp.blob
fastboot reboot
No dice.
Tried formatting from the “Wipe” menu via TWRP, Always get a TON of E:errors
E:error: I/O error
E:error opening “/data/---a whole list of entries ----”
Installing a new ROM shows the same fault.
Currently I can still access adb, fastboot and all TWRP functions but E drive won’t allow me to mount. When booting into TWRP I get a password request from the encryption setup (still know the password, so no problems getting by that). The problem seems to be limited to the /data/ folder.
I’ve tried to get logs off the device, but I can’t seem to get the logs to go to the external SD card so I can pull em.
Not for this problem, but I've seen posts about deleting nearly every bit of content via fastboot in response to mostly bricked devices due to loading wrong recovery. Although you didn't do that, perhaps a similar approach would work for you!?

I was thinking of using BrateloSlava's "[TOOLS] Command file install/check/repair" and just zero the whole /data partition (option 8) as that is where the errors show. I would like a second opinion before I try that.
Also the symptoms stink of an "Encryption Unsuccessful" error.
GRRRRREAT NEWS
Even though I couldn’t gain access to any folder in the /data folder, I went and ran BrateloSlava’s Tool anyways. Option 8 - FULL ZERO’n. It’s says it fails to mount the folders right off the start.
Go for a two hour walk or something this part takes forever
Odds are you’ll be like me and the device will still be trying to zero the device (which it never completed for me). Use the recovery's software to shut down the device (turn it off).
Turn back on the device, and reflash the recovery that you had before (If you don’t the recovery will have forgotten your encrypted password and you won’t be able to do much).
After you have flashed a new recovery, go back into recovery again. You’ll notice that there is no more encrypted password while logging in. Format your device, follow by a wipe for good measure and you have returned your device to working order. PHEW
Basically I was using TWRP to wipe my TF700T and I wiped the OS. Luckily I made a recovery on my SD, but the problem is that I can't get it to boot back into TWRP in order to run it. All the Power + Volume Down does is just cause the device to rumble. Powering on the device just lets it sit in the bootscreen. If I can get into the bootloader I can basically fix the machine. Problem I have remaining is that I can't seem to get into the bootloader.
The device calls itself APX when plugged into my computer now, if that means anything. I'm gonna try to drain the battery by leaving it on over night without the flash card. Maybe that'll do something.
Any suggestions on how to unbrick this thing? Or did I just succeed in turning a very expensive tablet into a very expensive paperweight?

Im having exactly the same problem, did you find a solution to this?
So far no results yet. I tried hitting the reset button on the side but all that did was lead me back to the boot screen. I read something about undoing the the hard boot using a series of override programs. But the problem is the documentation is so cluttered that I can't fathom the instructions (I'll try it again just in case.)
Bump update: So I called Asus and it turns out it's gonna cost 288$ to get the thing fixed by them. So I'm not doing that. I'm looking into other ways of recovery. I've got other multiple options I'm exploring at the moment. Like looking for a recycling program or a way to use the technology in a new way.
UPDATE X2
So I talked to a friend and the very fact that it sits at APX was a tipoff. Basically it means the recovery is shot but the Bootloader is OK. Meaning that the device isn't as bricked as I thought. What needs to be done is to download the android ADT bundle (google it) and from there get into the platform tools under command prompt, type "adb" then "adb devices" and finally "adb reboot recovery"
if it works the recovery should reflash and then using the backup restore the OS.
Granted I'm having trouble getting my comptuer to say "APX has been connected" due to a faulty data cable but I should be home free after this

Unfortunately if you can only get to APX mode and you don't have nvflash specific blobs for your device you are hard bricked...
Luckily I make a recovery file in my SD card wayy back when I did my first Cromi mod. It should still work if the forced recovery restores TWRP. Otherwise, yes, I might be hard bricked.
My friend, however, thinks there might be another way to force a OS past this block though. I'll have to see how this plays out.

Sorry it really doesn't look good, Maybe i can corrected but the device will fallback to APX mode if the bootloader is corrupted, without a bootloader you cant install/fix a recovery and without NvFlash blobs you cant fix the bootloader. Your two options are buy a new motherboard and replace it yourself or send it in for repair with Asus

As JTR says I'm pretty sure you can't fix this without replacing the hardware now. I don't think your friend really understands what APX mode is. YOu can't access the bootloader nor recovery. Without NVflash backup blobs you can't recover anything, there is no way to get your TWRP backups back on to the device and even if you could you have no working bootloader......
Ok, I've been reading around the forum for about a week, trying to solve a problem with an original moto g (falcon). Basically my cousin got the moto g a few years back, and I, in my ignorance, tried to root the device for him. What I can remember was oem unlocking the bootloader with Motorola's unlock code through their website and adb. then my cousin freaked about the warranty warning on the boot animation, and decided against it. So cut to now, I'm a little more experienced, the phone's years old now, and he'd like to refresh it with a new rom, which I suggested, trying to help him. So forgetting what I'd originally done those years ago, I started the process of rooting the phone, installing a custom recovery, to hopefully put a lighter rom on it for him.
OK so it's a UK Retail on tesco mobile, moto g xt1032 running Android 5.1.
in bootloader menu it says "Device Locked status 2", dunno what this is in relation to.
first I checked the bootloader was still unlocked, and adb said it was. so I tried to use CF-autoroot to finish the job, but there was issues. it restarted the phone into fastboot mode, but when the script started, pc end did nothing, on the phone it said, "flashing unlock" and just sat there for 10-15mins doing nothing (i left it the time, just incase it was doing it).
So i read a little more, and found because i'd already unlocked the bootloader, I could just flash a custom recovery and root from adb? so I downloaded the latest twrp and tried. I was unable to do so. it said the partition wasn't the right size? should have documented it, but really didn't expect to run into any problems.
So I restarted and tried to do my usual fallback, and flash the factory image and start again, But couldn't find a source for the specific img, and tried to keep fighting on.
So I noticed that the phone wouldn't respond to adb or fastboot once in fastboot mode, when in android with usb debugging, no problems, in fastboot, didn't show up as adb devices?
I tried booting into the recovery from the bootloader menu, and got a no command. So there isn't a recovery, and I can't flash a new one? if i could find the stock recovery, I would try that.
so apart from deleting all his apps and settings, I hadn't solved the problem at all, and had to leave the job there as I couldn't find a solution.
I know this isn't the most detailed, but I've done this with quiet a few phones now, and felt I was pretty competent. I see everyday as an excuse to learn more, and like to think I have humility. So, I'm assuming I did something those years ago to damage the recovery? I'm running out of ideas, and was hoping someone could point me in the right direction?
I've lurked on xda for years, and learned so much about this kind of thing through my past experiences, but I'm stumped this time, and feel obliged to resolve the problem, as it was me who caused it.
TL DR
Can't flash recovery, no command when I try to open recovery, trying to either factory image back, or root/custom recovery it.
any insight would be much appreciated.
Hi. I just rooted and installed CM13 on an old XT1034 about two days ago. I am also sort of a ROM noob, I have ROMed a few devices, but usually but following strict step by step guides I have found here on XDA. Over the years I have some minor understanding of the process now.
I also got the "No command screen" when trying to get into TWRP recovery. The issue seems to be that if you reboot via ADB and the ROM launches it will automatically rewrite the recovery to the stock one, and when you try to go to recovery from fastboot, it gives you the "no command" error. Apparently you can get to the stock recovery from there by a hardware key combo, something like holding up vol for 10 sec then a quick press of power (I can't remeber the exact key sequence or what forum I read it in). If it does this you have to reflash TWRP again. This issue is mentioned here (http://wiki.cyanogenmod.org/w/Install_CM_for_falcon) in step 8 about installing recovery. What I ended up doing was after the flash of TWRP via ADB, I manually powered down, then manually bood into fastboot by holding volume down and power, and selecting recovery. This was a bit fiddly and I had to attempt it a few times but eventually it worked and TWRP installed.
The issue with the phone not being recognized may be due to incorrect drivers. I had no issue with this because I installed the official driver package from Motorola. It is available in their website in the developer section. I don't have the URL right now.
Hopefully this helps, for me CM13 Official has been an a stable fresh start for this old device.
