Stuck in Boot Loop - Transformer TF300T Q&A, Help & Troubleshooting

Strange thing here....
Upgraded my tf300t to katkiss 6.0.
Worked great for about a month. Then it started doing screwy things, random restarts, etc.
Shutdown to boot into TWRP and reflash the ROM and now it is stuck in a boot loop.
If I try to boot into TWRP it still loops.....Any suggestions or hope here....probably something I just haven't had time to figure out or find yet.
Thanks

ADB & Fastboot:
TF300t Drivers
Command lines
adb shell
dd if=/dev/zero of=/dev/block/mmcblk0p4 bs=100 count=1
dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=16 count=1
TWRP (Use this line to fix TWRP):
adb reboot recovery
turn off and on again

Ok it has been a while, but here is the issue....
Start tablet in fastboot
When I plug the USB cable into the computer the green square that flashes around the RCK will stall for a moment as if it is trying to recognize something. However the tablet is not recognized by the computer anywhere in device manager.
I had some success on a machine once or twice with it being recognized in Windows 10, but then it would only be recognized intermittently. I attempted to connect it to another machine on Win 10, Vista and 7, but it is till not being recognized. Help...???

If not already done, please install "Minimal ADB and Fastboot" on your machine. Since you have startet it "C:\Programm Files (x86)\ Minimal ADB and Fastboot" appears. Then write adb devices and push enter. Your device should appear as serial number.
After that you may use the advised commands in the 2. post.

Installing ADB Minimal fastboot has nothing to do with whether or not the computer is recognizing the tablet at all. But just an FYI ADB Minimal fastboot is installed on the computer....

try this with adb command "adb shell recovery --wipe_data"

stuck on White HTC Screen

I rooted made a recovery image in clockwork. Then I flash a keyboard. I got stuck on the white htc screen. I then tried to restore. Still stuck on white screen. I can get recovery and boatloader. Any ideas on how to get out.
were you able to solve the problem?
I had the same kind of problem, if you have the hack kit then you can run adb command from your pc
Just plug in your phone (after turning it off) to your PC, open a command prompt as admin, navigate to tools> win and run the command
adb reboot recovery
this will restart your phone at the clockwork recovery
from there do a system wipe.
Then reboot.
Hope this helps

[Q] TF101G stuck on boot, recovery not working

OK, let's start from the beginning. I installed TWRP recovery, EOS 4 and KAT Kernel successfully today and I was quite happy with the results but decided to try Revolution HD. Since I am more used to ROM Manager, I decided to change TWRP to CWM and use it for recovery. After that things got messy. First of all CWM said that it can't find sd card and secondly my TF wouldn't boot up anymore after exiting recovery. I've been messing with it for hours and can't find a solution. It only got worse and for awhile the only way I could access it through ADB was to do a cold boot and it would get stuck at the spinning EOS logo, but atleast it would allow ADB access.
Last thing I tried is this and the tablet reboots, but it's still stuck on spinng EOS logo, but I don't have to do a cold boot to get stuck there anymore
AW: [Q] TF101G stuck on boot,cannot access recovery. Any way to fix via adb maybe?
So, for all those who have the same problem as I had, I found a solution and its a pretty easy one!
In my case, it seemed to be a permission problem concerning /dev/block/mmcblk0p3. So, I went through different threads and found a suitable solution here:
http://forum.xda-developers.com/show...530337&page=20.
All you have to do is to enter terminal emulator on your device (or use adb alternatively) and enter:
su
echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
reboot
You should see the asus eee pad screen with a blue progression bar and then it should boot normally. Thanks to partio for this hint! :thumbup:

If I select recovery after reboot, it will get stuck at Booting recovery kernel image. So any ideas what to do next ?
Edit: That's what is visible on my tab from QtADB
OK I've tried everything I could find but nothing
Computer recognizes it fine when it's cold booting and as you can see, ADB works on it but can't get fastboot to work. I guess the solution would be to get a working recovery on it again, but I can't figure out how without fastboot.

Don't use ROM manager.
Get adb access and use it to run that command you quoted, then reboot, run the command again, and run adb push recoveryblob /sdcard/ then dd if=/sdcard/recoveryblob of=/dev/block/mmcblk0p4 to restore a working recovery. Then from there mount and reflash.

OK, tried it but I couldn't complete it.
The first part works ok and after reboot I see the blue line filling up and after that the usual EeePad screen and it boots to EOS loading screen and I can get ADB access again.
But after I have to write "adb push recoveryblob /sdcard/" CMD says
Daemon not running starting it nor on port 5038
Daemon started successfully
And after that it just doesn't do a thing and then it reboots and I can't enter the final code. And under directory tree the sdcard is not a folder but it's just a file or smthing like that "sdcard -> /storage/emulated/legacy" is written.
EDIT:
Man, I would kiss you if I could ! Worked, finally it worked !
So the problem was, that it couldn't find sdcard and so it rebooted. Changed the sdcard to another directory, /dev in my case and after that it completed it and booted perfectly into recovery. AWESOME !

adb commands not working in fastboot mode. Is it normal?

I was trying to flash a custom ROM on my moto g xt1033. I used choosing the zip from USB otg after wiping and formatting everyrhing but. It flashed but a black screen came instead of cm logo and I was stuck at welcome to cm screen without touchscreen working. http://forum.xda-developers.com/mot...4-4-4-help-t3019082/post58587594#post58587594
Then I tried side loading or pushing method. But problem is adb commands are not working in fastboot mode. They are working when phone is switched on. (Adb devices show serial number and device in normal mode) Fastboot commands are working fine in fastboot mode but not adb. When I type adb devices in fastboot mode there is nothing after list of device attached. So adb push or adb side load give me waiting for device or device not found result. Is it normal. Earlier I have latest Motorola device manager and latest android SDK. Tried uninstalling and installing them, tried changing USB ports, tried rebooting the phone and restarting windows pc several times but still no luck.!!
Yes, it's normal that ADB commands do not work in Fastboot mode. But you can access custom recovery from the fastboot screen.
@lost101 if adb commands do not work in fastboot mode then how "adb sideload" works when we clean install a ROM? Many threads at XDA say it should work

You have to be in a custom recovery (TWRP, CWM, Philz Touch) and enable the 'adb sideload' option.

It doesn't work on all versions of Windows; I think I've had it working in Windows 7. But I mainly use it in Linux - where no driver is required.
I also have windows 7.. Thanks Anyway

It's a driver issue. Your phone is not being recognised. If you boot a Linux LiveCD from DVD / USB, you can access recovery mode ADB that way.
sudo apt-get install android-tools-fastboot​
Not sure if this will help but, after completely wiping my phone, I installed TWRP using fastboot commands, booted to TWRP, mount, copy ROM to moto g, and install using TWRP.
If you are in fastboot mode, type fastboot devices and see what happens.

Fastboot Devices command works flawlessly in fastboot mode. I can flash .IMG files. But none of adb commands working. When I type adb devices there is no result after List of Devices attached. So I can't sideload anything
I'm not 100% sure how adb works on the moto g but I don't think adb commands work in fastboot mode. When I connect my moto G to my computer after the ROM has booted and I am at the phone's desktop, I type "adb devices" and I see my device listed. Then I type "adb reboot-bootloader" to get into fastboot mode and adb commands no longer work.
I have Philz Touch on my Moto G and sideloading is an option. I don't think you can side load from fastboot.

I have no idea as I have never used adb to install anything except apk files when the phone has been booted to the desktop.
I always use fastboot commands to install recovery and install stock ROMs.
Using adb to side load may refer to the aibility to install files while the phone is running.

OK leave it. Do you have any idea how to increase 2g/3g speed. Any trick/mod/script?? I flashed cm11 quarx build and internet is painfully slow
Edit- no sideload means pushing a flashable zip to the root of internal storage when phone is in recovery mode. We do it for clean installing ROMs.(Format and wipe everything). After format there is no operating system left in phone so we do sideload rom

Sorry, I don't know how to increase speed except try a different radio/modem on your phone. I rarely use data on my phone because I have an iPad with LTE.

Sounds like your fastboot driver is working fine but your adb driver is not...go into your custom recovery and then check Device Manager in Windows to see if you have all your drivers working properly.
If you are having adb driver issues you could try the Universal adb driver setup file attached.
adb commands don't work in fastboot mode. Install a recovery (Preferably TWRP because I forget how CWM's adb sideload works). For TWRP, go to advanced, then adb sideload. Make sure to install the adb drivers tho, or else the sideload won't work. If you're sticking with stock, press the Vol+ button for about 15 secs, then tap the power button. Use the Vol- and + keys too scroll. There should be an option like "Install firmware through adb" or something. Scroll to that, then hit the power button to go to that option. Then, just sideload the firmware.
Check device manager 1st phone is conected properly
adb has no relation to fastboot.adb will not work while in fastboot, it never worked that way either.
There is no sideload while in fastboot, you're confusing it with the adb sideload, that has nothing to do with fastboot.
Reading and comprehension are desirable here.

TF300 boot loop, twrp, no fastboot

Hi druids of android,
I have an unlocked Asus TF300 with CM-11 and TWRP 2.8.1.0
Recently I've updated CM via OTA to the latest available snapshot and after that I've done factory reset from android UI (I lost my password so I decided to create a new g. account)
Now my tablet after reset shows Asus logo, 4 penguins and it stucks on blue striped treamwin splash screen.
Splash screen flickers every 6s. I see the device by lsusb, adb devices for 5 seconds, after the device disappears for a while and it backs again. I can do some adb commands like adb shell ls, cat, rm but I can't do any fastboot command to flash recovery or system.
Any fastboot call ends with 'waiting for device'. I call it through sudo and I've configured udev according to wiki.cyanogenmod.org/w/UDEV
I've tried restart tablet with power+volUp, power+volDown, with the same results descibed above. PaperClip+VolUp turns the tablet off.
I've found /cache/recovery/recovery.log file. (can't attach whole file because I'm a fresh member)
Partitions were mounted and the loop begins after:
Code:
SELinux contexts loaded from /file_contexts
Full SELinux support is present.
I:Boot command: boot-recovery
I'm fighting with it a few evenings and I decided to ask You for help.
I have the exact same problem. Happened last night after the Wipe Data option.
I have since read that that is a horrible thing to do.
I did try this - http://forum.xda-developers.com/showthread.php?p=63269550&nocache=1#post63269550
But I am unable to get to the fastboot screen still after dd-ing. The data partition dd took hours and hours. Left it overnight.
Help would be appreciated.
SOLVED!
Got TWRP working again!!

I was unable to get the adb shell commands working separately after going into #.
So I just put in
Code:
adb shell "dd if=/dev/zero of=/dev/block/mmcblk0p4 bs=100 count=1"
adb shell "dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=16 count=1"
This should fix it!
Hello guys.Finally i found solve for my TF300T loop on TEAMWIN logo.I read many threads in XDA forum for this problem but nothing happens .I had no fastboot with adb ,no recovery menu with adb and combinaiton keys until get this command "adb shell recovery --wipe_data" found.First you must install naked drivers 0.73 http://forum.xda-developers.com/showthread.php?t=2139767.Then plug usb tablet to pc(windows) and open cmd and enter the command "adb shell recovery --wipe_data"and press enter.
Sorry for my english
Gonna try this tonight. Did the same thing to my tablet yesterday. I am running the latest TWRP(Kang) and Katkiss MM 6.0.1 ver 24 Did a wipe of the cache and dalvik as I was having some issues. It then started random rebooting into Android. So I went into bootloader screen and tried to start recovery and accidently hit wipe data and got the boot loop. Now it just boots and reboots about 3 times and shuts down. I will try the naked drivers and your commands.
To point out ,that before i found solution fo my tablet,i had no fastbout wih comb-keys .My loop was only on the TWRP LOGO and never restarting or closing alone,until to press power button for 20s about to restart tablet or press reset button + power button for 20s to shut down tablet.I hope find solution and sorry fot my english again.
Thanks to tobdaryl member

tf101g soft brick problem use fastboot

Hi, i have tf101g b90 sbk2,
went into soft brick because I installed first CWM recovery and then TWRP not corrected. The shell must be reinstalled. adb works well and read the device with your correct serial number. . The problem is fastboot, i write fastboot device in prompt and I see nothing. When I give a command, I read 'waiting for any device. I think . I think the drivers are installed well with nacked drivers,
when it is in adb mode i have installed driver asus transformer adb interface, when in fastboot mode i have installed driver asus fastboot interface. To go to fastboot mode I press both volume buttons and the serial number of device becomes 1111111111111111111, thinking that this is the correct serial for fastboot mode. At this point I think the problems are: either I need the root (which I can not do), or the drivers are installed badly (even if I do not think), or I do not go correctly in fastboot mode. The strange thing is that in adb I go well but in fastboot no. In the end I would like to run the fastboot flashall command. Thank you
