Asus TF300T Boot Loop without USB Debugging Mode enabled. HELP!

[swesho87]

Hi,
I recently downloaded an app called Ram Manager Pro and on the app it had an option to "change VM Heap size" not knowing what my default size was, or even what VM Heap was I started toying with and set it to a low setting and it prompted me to reboot. so I did and now it doesn't have enough VM heap to boot. and the worst part is USB Debugging mode is Disabled >.< My TF300T is rooted and I tried to use ADB and Fastboot but I can't find the USB drivers for the MTP ANYWHERE on the net. I also tried putting the newest update .zip on the root of my external microSD card and recovering it by holding the power + vol down and recovery. I get a dead android with a caution sign on his chest. any help would be GREATLY appreciated!!!

Welcome to the forum!

Did you unzip the update 1 time (it will still be a .zip file)?

Also, try getting the Android SDK to get the ADB drivers.

I unzipped the first package to get the other US_epaduser_blahblah.zip and put that on the root of my micro sd card. i checked and it is formatted to FAT32. still can't seem to find it in recovery. as is I only have 3 cw options. recovery(which has dead android) wipe data and android coldboot. and as far as SDK i'm working on that. i'm being stationed in indonesia at the time. internet sucks here. i'll update asap.

i downloaded sdk but its not finding my device to download the drivers. i really need to find a way to get usb debugging mode on or find a work around for ADB

[swesho87]

does anyone know of a way or if at all possible to get CWM installed through a micro SD card?

[swesho87]

ok so i have downloaded the correct usb drivers for the asus mtp and installed. but since my debugging mode is disabled it says "this device cannot start. code 10" under device manager which means i cant use adb or fastboot?? is there any work around for this?

Alright I got it back up and running fine. thanks Transformerforums (not!) ok. so this is the RIGHT way to flash a firmware update from a micro SD. you dont just unzip and place on your SDcard. You have to RENAME it to "EP201_768_SDUPDATE.zip" place it on the root of your microSD, then reboot into recovery (hold Power + Vol+) and she'll pretty much take it from there. I love how simple it actually was. and I'm loving having my tablet back after a week of inactivity.

I'm in Chile now, I am a novice user. Something similar happens to me. Home my TF300T and I get a message "Encryption unsuccessful". I tried to recovery it but I have not succeeded. Try indicated by you (RENAME it to "EP201_768_SDUPDATE.zip" place it on the root of your microSD), but appear the same message.
It took several weeks with the problem and I have not been solved. Could you give me some tips.

Please, please ....

First thing is a word on VM heap size and why you need to know what you are changing
-"This setting is simply the maximum amount of heap space (read: memory) a single instance of the Dalvik VM (read: application) can obtain."

@perzeo
do a data wipe in the cold boot menu (power + volume down, wait for the icons and select wipe data) you will lose everything, but in my experience, this may be your only hope to get rid of your encryption (I'm assuming you encrypted the tablet prior to updating?). Then try the update.
