Hello all,
I think my TF300T is definitely bricked, but I'd rather have your opinion before trying to switch motherboards....
What are the symptoms :
When I power on the tablet, I have for a few seconds the Asus screen (with "tablet unlocked" on the top), then this Asus screen blinks and the tablet launches twrp automatically (without showing the bootloader (recovery,android,wipe) screen, it goes directly to twrp).
But TWRP won't launch properly, it is stuck in twrp start screen for 30 seconds, then the tablets restarts automatically and the loop I described starts from the beginning.
I cannot event switch off the tablet holding the power button, can only restart it.
I started many combinations described in several posts here to obtain the bootloader screen (I've seen a post with a least seven methods, the only one I did not try yet is to open the tablet and unplug the battery ), none succeeded !
I previously (before the problems) had good adb/fastboot connection with my computer, none of it is working now ! (I've seen a post of someone saying that he had a proper connection for only a few seconds during boot, I tried the steps he described but it did not work either, If I constantly launch "adb devices" or "fastboot devices" commands , I never obtain a response from the tablet. ( I also did the drivers replacements )
How did I get there :
I wanted to install katkiss , before that I installed twrp and formatted /data in f2fs.
After installing twrp I saw that it could not launch properly (it could launch only after flashing it , the next boot it was not working anymore, stuck in launch screen), and that the filesystem was not accessible in twrp any more .
That's where I guess I did the biggest mistake, I used the wipe option in the bootloader (I know now that it was A VERY BAD IDEA ... ) .
I seemed to me that , to perform this wipe, the tablet launched twrp and freezed , but I can be wrong.
I suspect that the tablet saved somewhere that is has to launch twrp on boot to perform the wipe, but as twrp is not launching correctly, the tablets restarts, sees that it has to launch twrp... , then loop again ...
Am I right ? could it be possible that the tablets stored somewhere to automatically start twrp on boot ?
and now ?
Every ways to fix it I read implies having adb or fastboot (I read about nvflash but never used it before, so it seems too late), butI can't use it at the moment !
Any Suggestions / advice ?
Thanks in advance,

I guess you've tried this, but power on by holding power+down vol. Should get you to bootloader. Keep holding it until bootloader screen appears. Holding power for 10-20 seconds should power down tablet.

Hi
Thanks for your answer.
Yup I tried it, I tried all the ways I found on the internet (there's a post somewhere in this forum where 7 or 8 different methods are explained) none of it worked.
So, did you have TWRP loaded on the regular flash partition vs. the Recovery partition?
Is it possible you were running TWRP as the Operating System, and when you wiped the partition, you destroyed the OS?
TF300T bricked?

Hi, Had the same thing happen to mine. Hold own power to force shutdown then hold volume down and recovery screen should come up. Worked for me.!
@hardballer83
Unfortunately a bad situation caused by yourself!
If you don't have any fastboot or ADB-access to your tablet now, only a new MB can bring your device back to life again.

While I was playing with my TF700 the other day I accidentally put it upside down resulting in pressing (& holding) the power bottom & volume down .. the device restarted into "Safe Mode"
I tried to get rid of it, but apparently I did something stupid which resulting in boot logo loop (the device is stuck at the second ASUS screen and refuses to boot)
* Note my device is Unlocked & I'm running the latest CleanRom version and I am kinda' experienced user :silly:
Anyway I googled this and I tried the following steps with NO success:
- Cold boot
- Wiping caches
- I also tried to re-flash a rom
which left me only with formatting & wiping data, BUT I tried this thing and it actually worked!
From TWRP I restored my last back up (which was a bit old) But whatever, It actually worked! and I have no problems whatsoever, everything seems to run as before, I also tried to reboot the device and it's still working!
I felt I should share this info with you, it might help someone :highfive:
Current Status of my TF700:
-Boot looping with Asus "Inspiring Innovation - Persisten Perfection" logo. Approximately 5 seconds between reboots, with a vibrate every time it reboots.
-It says "Device is Unlocked" in the top left.
-Holding power for a long time (over 20s) will shut it off, and vibrate, but then it immediately vibrates again and resumes the bootloop.
-I cannot get it into the bootloader with Power + Vol Down. That combination does nothing.
-If I use the pinhole button, as long as I hold it, the screen remains blank. As soon as I release it again, the bootloop resumes immediately.
-It does not get to the second "shiny" Asus logo.
-It doesn't get far enough to recognize a new firmware file on the microSD card.
How I got to this point:
Stock ever since I bought it up until a few days ago. I decided it was time to root, unlock, install TWRP, and install CWM. I never got that far.
1. I unlocked first. I believe it was successful because it has said "Device is Unlocked" ever since.
2. I tried to root with the debugfs method. It reported it was successful, but despite several attempts, it was unsuccessful.
3. I tried using GooManager to install TWRP. It never worked.
4. I discovered that I wasn't running the latest Asus firmware. I then upgraded it. It ran successfully. (V10.6.1.14.10)
5. I tried rooting with Motochopper. It reported success. But it didn't work. I then discovered it wouldn't work with V10.6.1.14.10.
6. I then tried installing TWRP via fastboot. It reported success, but Power+VolDown didn't get me into TWRP. Nothing seemed to load TWRP. In case it's relevant, I was having trouble where Windows was saying there was a problem with the Bootloader Interface Driver, and after several reboots, I was able to get fastboot to reportedly load TWRP. It reported success, but I never saw TWRP.
7. I booted into Recovery, the latest version that said something to the effect of, "USB recovery loaded" or something, with 3 icons: RCK, Android, and Wipe Data. This is the only recovery I was ever able to see, by the way. I then selected "Wipe Data" hoping it would give me a new starting point.
Once it rebooted, it has been stuck in this bootloop. Have I royally screwed myself, or is there a way to recover?
Please ask any questions, I will answer them to the best of my ability. In the meantime, I will hope to run the power down on the tablet in the hopes it will make a difference.

Power+VolDown activates the bootloader menu - this is the screen with the 3 icons, where you can use fastboot. Since you needed to go there to install TWRP via fastboot, you should have known that Power+VolDown doesn't get you into TWRP - you'd have to press VolUp in the bootloader menu, to activate RCK.

Selecting "Wipe data" from the bootloader menu with a broken recovery is the best known way to brick a TF700. This can only be recovered via nvflash, which you can't use since you never got far enough to extract the required files from your tablet while it still worked. Your only option now is a new mainboard.
Well, crap. RCK never did anything except show a loading bar then reboot.
Thanks for the reply.
...from my phone...
Anyone know of a place that sells 64gb mainboards? Not finding anything thus far...

in case anyone cares, I swapped the motherboard out with one from ebay, and it booted right up.
so today i went to unlock and flash CM 10.1 on my tablet.
unlocking went smoothly
installing clockwork recovery went fine
installing cm10.1 and gapps went fine
once i booted into cm successfully, i checked the internal storage to see if it was clear. it wasn't, so i went to settings, backup and reset, and done a factory reset. now i'm stuck on this one screen and i dont know what it is.
i've held the power button and volume down until the tablet restarts and that results in the same thing.
i've tried power and volume up. that seems to start the tablet but the screen stays blank. i connected it to the computer and my computer installed an APX or APTX or something like that driver.
i've tried holding power, volume up and down, and that does the same as the power and volume up.
i'm very new to installing custom recoveries and roms. can anyone give me an idea on whats happened
Once you have a custom recovery installed you should NEVER wipe from the system settings or the bootloader menu. You wipe from your recovery.
If you do that, the bootloader seems to write a command to the misc partition to reboot into recovery.
And that is the loop you seem to be stuck in.
You can try _that's method to clear the misc partition from here: http://forum.xda-developers.com/showthread.php?t=2528313
Read the whole thread, salvation may be found in post 7.
If that does not work, you could try this:
http://forum.xda-developers.com/showthread.php?t=2399698
buster99's method may be another way to enable you to boot into the bootloader and flash a working recovery.
Good luck!
Thanks for the tip. I'll remember to do that next time. As of now it is fixed. I found a post on the cyanogen forum of someone who done the same thing. And he said he had to wait a painful 6+ hours of that screen I posted. Lucky for me it was only a ~45 minute wait. So all is good. Cyanogen is running. Recovery is working. All the stress is gone.
Hello,
I am brand new to this forum and to android problems.... so forgive "silly questions".
I got a used tf300t which was reset back to factory settings.
I installed the dolphin browser and the last thing I did was installing the opera mobile browser.
Since that the cyanogenmod animation pops up right at the boot process and now and then it finishes booting, but when I wipe the screen in order to unlock it the cy-animation appears again.
Yesterday I got an error message that a system process was shutdown with a java null pointer exception for ..... any language process. (did not note the error message unfortuanately).
This brought to my mind that I changed some keyboard setting for the german keyboard layout and this is very likely the cause of the problem.
Now I wanted to reset the device back to it's factory settings, but I cannot boot into the recovery mode. Pressing power- and volume down button just flashes the screen with the asus logo but when I release the buttons, the cyanogenmode animation again appears.
So how can I "hard-reset" the device and btw. is this cyanogenmod thing really necessary?
thanks a bunch in advance and cheers

update: can now boot into TWRP
update#2: I killed it
I used the wipe option (think it was called this way) for a factory reset - and now it is stuck at the asus logo while booting.
Connect to a PC with cable, see if ADB recognizes it.
If it does, issue (in terminal/command line):
Code:
adb reboot bootloader
Wait for it reboot.
Verify fastboot connection
Code:
fastboot devices
If it is recognized, you need to re-flash latest stock firmware (blob), that can be found on Asus website. Make sure you get the right (geo)version for your device (ie: US/JP/WR...)
To flash the stock firmware, find the directions on this forum.

sorry for the delayed answer, but thank you soooo much, I will try it out immediately. However befor I got that troubles I connected it to a PC but it did't get recognized.
Well we'll see...
to be continued
I got it, I got it, I got it
the problem was a different one called cyanogenmod.
When resetting the device the cyanogenmod got uninstalled and therefore restarting was not possible.
I found a backup file of the cyanogenmod and reinstalled it ... and it works
thanks a bunch for your help
Hello everyone, I have lots of issues with this tablet since I bought it. It works painfully slow, yet resetting it doesn't change anything, still the same problem. I also tried to root it via Kingroot and it werk, however it took me lot of time due to the system being unresponsive / unstable and almost useless. It comes with android 4.0.3 and I also tried looking up for any possibilites to reinstall the firmware since I'm extremely sure it could be caused from the firmware it also got installed from the factory. I also tried searching for custom roms and other ways around for TWRP or any custom recovery, but no result. I also tried up with the Flashify app to try extracting / backing up / dumping the recovery and the kernel but the app freezes up. I also tried a possibility to update the firmware from their official page, hence it failed to do so since it gives an error in their flashing software that dosen't tell me nor it logs it what it could be caused up from the connecting part.
primux.es/producto/tablets/tablet-primux-siroco-2-101/189
(not sure if anyone understands spanish thought but I can translate if needed)
This is the page from where I tried to download and install their software and their firmware down below on the page. primuxcomputers.es/primux/siroco2upgrade.pdf
There are the instructions where I tried to follow but at the "Imagen 9: Icono" part got me stuck in there. It requests me to insert the cable in the tablet holding the "Home" button and while holding it, plugging in the USB cable throught PC, and tap quickly the "Power" button 3 times. However it gives me a red X icon and yet nothing shows up in the devices: No ID, no other kind of detection no logs no nothing. After it showed up the X on the status, it disconnects itself and it changes to ready / green icon and plugs itself in again but nothing really happens to detect it again thought.
I also tried to boot in recovery mode but nothing happens menawhile Flashify keeps on the rebooting in recovery mode in loop doing nothing else... I'm seriously in pain with this tablet. And if you ask me to return it, not gonna even bother doing that..
I seriously hope any answer very soon and don't get dissapointed by the ignorance of this topic..
