[Q] Asus TF300T boot loop CM11/OMNIROM logos - Transformer TF300T Q&A, Help & Troubleshooting

(backstory) Hi, ive had an Asus TF300T, for about 3 years now, unlocked, rooted it pretty early on... cycled between cyanogenmod and omnirom quite a bit, without really any major issues. Until today, i was running Cyanogenmods latest nightly build (CM11 Nov 5 2014), it worked just as any other nightly does a few bugs here and there, but nothing major and i hadn't done any major flashing or modding to the device. On my home from university, I turned my tablet off. And when i got home i plugged in the charger, and just as always the tablet turned on, showed the stock Asus screen, then changed to the Android boot animation... the animation then suddenly froze, and the device went into a boot loop... continuously... I dont know whats weong with it... tried to do a factory reset, i tried reinstalling the ROM, tried installing omnirom, but that got stuck on the OmniRom animation...
Im running Asus build 10.6.1.27.5
I had TWRP v2.7.0.1 installed but have now no longer works
id really hope there is a solution for this!
Thanks!
Edit: I dont know why, but when i try using fastboot or adb, the device isnt recognized. It doesnt show up on device manager either. I dont know if its the cable cause i bought it new, it says its can sync data, or a faulty charge/sync port....

^THIS!
I was just to open a similar thread, then i saw your post. I join your request for help!
A month ago i have done a favor to a friend by unlocking his tf300t and installing CM11 on it. A few days ago he comes to me with this problem. I've tried anything but still no success:
- restore a backup done before flashing CM11 --> restore ends correctly but the problem remains
- flash a rom (CM11 and OmniRom) --> flash ends correctly but the problem remains
- flash the stock firmware found on asus website (WW_epad-user-10.6.1.27.5.zip, the SKU is correct for my version) --> the flash process stuck (i had to force restart the tablet after almost 2 hours of "flashing")
Since the boot animation changes according to the rom, i suppose the flashing process works. But the problem remains: after a few seconds the animation freeze and the device restarts, in loop.
Informations on the system:
- build 10.6.1.27.5
- TWRP v2.7.0.1 (working!)
- adb works (i managed to set /data as rw and push the .zip file to flash)
- fastboot should work
Please help! I feel a bit responsible for bricking my friend's device

SOLVED!
Finally!
I had already tried this method, before requesting for help, but the first time didn't worked... I don't know why this evening the tablet decided to collaborate:

That worked for me! :victory:

SiyahKernel s3-v1.8.8
Posted on January 13, 2013
Changelog
rebased on i9300 update7 sources (sudden-death issue is supposedly fixed in this source drop)
reverted temporary fix for exynos-mem exploit as i9300-update7 sources already fix that
cm10.1 is now supported in dual-boot configurations
1.8.7->1.8.8: fixed cm10.1 not booting when installed as 2ndROM (a tiny typo in ramfs)
BUT,it doesn't work anyway (just trying now at it's stuck on the boot screen)
Just try it and report back! :good:
You do realize that the siyah kernel is for the international S3 which has different hardware then our s3? If you are using a kernel for a different phone then of course it wont boot....

Flash problems
I've had installs stick at the boot animation or shortly thereafter several times. Usually it's because of a dumb mistake. The only thing that's consistently worked for me is flashing back to stock VZ firmware via Odin and doing the whole process over from root through installation. It sucks but it always works.
Howdy.
I've just flashed CyanogenMod 10.1 - 20130315 to my droid 4 with Safestrap, and I haven't been able to boot into it; the cyanogenmod splash screen with the rotating wheel graphic shows up, but it spins for upwards of 40 minutes without doing anything.
I followed the guide on the cyanogenmod wiki for the droid 4 device. The forum won't let me post a link to it.
Before I installed I wiped / factory reset, and after install I wiped cache/dalvik; still no dice. I've tried doing the same process several times (even wiking the system before trying to reflash), but the same result has always occurred: ever unhelpful eternal wheel...
I'm a bit at my wits end; I haven't been able to find any other information about this that wasn't solved by wiping cache / dalvik, so I turn to y'all for help.
Same here
I installed Cyanogenmod 10.1 with CWM the link:[Recovery/Bootstrap][5-sep-2012] CWM Touch recovery v6.0.1.1 - xda-developers and i went ahead and installed the mod: cm-10.1-20130211 all went fine untill i noticed that my camera is not working (not a big deal) but then i noticed that my phone only saw 488MB out of my 32GB this was un acceptable after i found how to connect my phone to my pc so it showed up as a storage device do that i copied the same mob but a different version (cm-10.1-20130129_v2) so i went ahead and booted into Android system recovery <3e> and i did a factory reset and then i said oh f*** i need CWMR to install the thing so i just waited for it to do its thing and then reboted the device thinking after i boot up i will reinstall CWMR but i was never able to boot because im stuck on the boot animation. Been waiting for +20min or so and nothing please help me what can i do this is my only phone please help
help with CM10.1 ROM issue
Hi folks,
this is my first post on XDA. I have a Sprint htc EVO 4G LTE phone which was running on JB.
Thought of root and flash with CM. So, first I unlocked the bootloader using htc dev and installed TWRP custom recovery and then rooted.
Then I flashed the stable CM 10 then flashed gapps which is compatible for CM 10 version. so far so good. oh, btw I did nandroid backup before flash and also wiped to factory reset, cache and Delvic cache.
After the flash i clicked on reboot system and I see the Cyanogenmod boot, but its stuck at that stage and I waited for more than an hour. No luck.
Thank god I did back up before this, otherwise not sure what I'm gonna do.
But, could someone tell me why it gets stuck at this point. I know some of you guys had this problem. I searched everywhere but didn't get help. I thought of posting this in android development forum, but as a newbie I can't do that.
Please help me out.
P.S: when I'm on boot screen (power button + vol down button) I see unlocked at the top but I also have TAMPERED in red color on top of that. Was this normal? or do you think that is causing the problem? and what should I do now?
(First of all I am not an expert)
It happens sometimes about 1/10 of every flashes I did with cm10
It might because some files didn't get copied or got corrupted.
Just try this method
Format data
Format system
Format cache
Wipe dalvick cache and factory reset
Now flash the ROM
Hit thanks if I helped

(First of all I am not an expert)
First wipe every thing(system,data,cache,dalvick,android secure....)
Now install ROM,
Wait don't install gapps
Now find an extended cm10.1 kernel or lupus kernel(or such kernels) for your device and flash it via pc
I prefer flashing kernel after installing the rom

Ask in the Xperia X10 mini forums.
Three-finger salute
Ran into this situation today when I tried to restore a backup and I couldn't get past the CM10 logo on bootup. Holding down all three buttons, power, volume up and down, got me back to the Clockworkmod boot screen.
ETA: Sorry, posted in wrong forum. My situation pertained to a Samsung Galaxy 5 Media Player.

Trouble while installing CM through ROM Installer

Hi everybody,
First of all, I must tell you that I've been using Android devices for over 3 years. So, I'm not a total newbie with Android. I must say that I've always been using Stock Android so far. Which makes me a real amateur in customisation.
That been said, here's my actual problem. I have rooted my tablet and unlocked the bootloader through the Transformer Toolkit available on Asus website following a step by step walkthrough. Everything went well. I have SuperSU installed and I'm rooted. Also, I have that little message saying my bootloader is unlocked when I turn my tablet on. No issue yet.
Since I'm still an amateur in installing custom ROM, I downloaded ROM Installer which is supposed to do all the dirty work for you. I chose CM 10.1.3 Stable since I wasn't interested in Nigthly yet. It downloaded normally. Once that was done, I used the ''Install ROM from SD Card'' option. It then rebooted in TWRP Recovery Mode, did a Backup and I wiped cache & Dalvik. It did what it had to.
Now, the tablet rebooted and the CynagenMod logo appeared with a blue circle spinning. Visually, it seemed to do something like an installation or something so I let it run all night. This morning, it hadn't change. The logo is still there with the spinning blue line. I can't do anything, no icon, nothing. I rebooted my tablet by holding the power button a few seconds. It restarted, showed the Asus logo and went back to the CyanogenMod logo again. Same thing as yesterday. I'm stuck there. Whatever I do, I can't get pass that logo.
My question is... Is there something I did wrong ? Otherwise, is there a way to get back to my stock 4.2.1 Android version ? I'm kinda afraid to do anything since I don't want to brick my tab.
I'm awaiting your tips and comments. Oh and please, don't be too harsh, English isn't my primary language and I tried to be as clear as possible. If you need more information, don't hesitate to ask.
Thanks in advance
I do not run CM roms, but it sounds as if you are on the wrong bootloader. Check here: http://forum.xda-developers.com/showthread.php?t=1957660
Try to get into TWRP by holding Volume Down and Power buttons. Hopefully you made a nandroid before you flashed??? Restore it and you are back on your stock rom.
Or copy the Asus firmware on a microSD (unzip the downloaded file once on your computer, put the resulting zip on the microSD) and flash that in TWRP.
But you will loose your custom recovery and probably all data if you do this, and will have to start from scratch.
Thanks, I was able to restore my recovery and went back to my Stock ROM.
I tried flashing CROMI and it worked at first try. Now this pad is a bomb!

[Q] TF101 won't boot

Ok, so I gave my wife my old TF101 when I got the 701. I reflashed it with a fresh install of timduru's KatKiss ROM. It's been running reasonably well aside from random reboots. all of a sudden, yesterday it stopped booting up at all. It shows the normal Asus flash screen, but then when it shows the OS specific one (in this case, the weird little picture of timduru's meerkat thing...) it's just flashing random little bits of tha tpitcure all over different parts of the screen an some sort of random flickering and never going past it. I can still boot to the recovery normally, so I wiped it and tried reflashing the same ROM and ended up with the same thing. Tonight I plan to try to download the newer version of the ROM and try, but I fear I may be SOL. Any other suggestions?
Have you tried wiping everything 100% in TWRP Recovery?
Including Data etc ?

Yes, I did that. Still no good. I'm pretty much screwed, aren't I?
If your TF serial number starts B6O or lower, some B7Os too, then it is SBK1, which means you can use NVFLASHable ROMs - they delete and remake every partition on the TF and reinstall stock ROM - you could try that in case the sdcard is corrupt
stuck at TWRP screen, failed to flash bootloader
Hello everyone,
Not to thread jack but I have a similar problem and instead of opening a new thread I decided to revive this one.
I have a similar problem that my TF101 has been working flawlessly for many years. It is rooted and was running 4.3 ROM. As of yesterday, it just won't boot at all. It has been stuck at the NVidia screen and just sits there. I tried to enter recovery mode by using volume(-) + power and the unit presents the TWRP logo and just loops as well by showing the TWRP screen (3 seconds) then going blank for a second then showing TWRP screen again in a cycle. I downloaded and tried Easyflasher and Brks toolkit and nothing can complete the flash. I can enter MTP mode which the computer can see the device but the manufacturer name and model are not-recognized. I can also enter APX mode but while trying to flash anything I get an error message (error, cannot flash bootloader) and the computer dings (device disconnects).
I have been trying for a day now and have run out of ideas.
Has the unit finally bit the dust? Does any one out there have any more ideas or suggestions on what to try next?
TIA for any help provided.

[Q] How-to restore a TF300T with the newest firmware that is not starting up

Dear guys and girls,
I have a problem. Since 2 days my tf300t is for some reason not starting up anymore. The start screen does not go away. Before it worked like a charm. I have tried almost everything, I can think of. As far as I know the latest firmware is installed. The problem is also that the tablet isn't in developer mode. So my options are limited afaik to fastboot. I have installed the naked drivers version 0.73. But windows is saying that the device is not started. Only fastboot is started as device. I have tried to reinstall the firmware by usb, but to no avail. It sends but doesn't write... I have drained the battery to zero level. Can anyone help me with this? What am I missing?
<>< A Dieu

I'm also having this same issue. Tablet was working fine and then froze up. After rebooting we are now stuck on the Asus screen with the circular logo going. Waited over an hour with no change. Tried to boot into recovery and recovery crashes and gives me Error! This is a stock tablet that hasn't been unlocked or anything.
Update: Did a Data Wipe and the device rebooted and came up. Doing all the updates again. Hopefully it wont mess up again.
So you have an unlocked bootloader ?

[Q] No ROMs work after flash & touchscreen doesn't work

I need help. I've had my old TF101 for a couple of years now. I was running KatKiss 4.3 when one day, I plugged it into an old soundboard to sound test some speakers. For some reason this sent it into a bootloop (it did the same to my G2, but I got it out easily). I figured it was not a big deal since I get into bootloops all the time, but I was shocked when I booted into TWRP and the touchscreen wouldn't work! So I rebooted it over and over but it still wouldn't boot regularly and TWRP wouldn't accept touches. I reflashed TWRP through adb (which worked in TWRP) and still nothing. Then I downloaded some TF101 unbrick tool that utilized nvflash, but it kept getting errors because it was missing files. After I used that, my tablet screen seemingly wouldn't turn on! I tried EasyFlasher with sbk2 (cause mine's a b70) but that did nothing. I was about ready to give up, when I stumbled across a thread here where a guy's tablet was stuck booting into apx mode. I guessed that that might explain the screen not turning on, so I tried the solution there, which involved another nvflash tool that was designed just to flash the base boot stuff, no ROM. This worked. After this I tried EasyFlasher again (with sbk1 this time) to get the Asus stock ROM, and it seemed to work, but the tablet wouldn't finish booting (I let it boot for over a half an hour). I flashed TWRP and some custom touchscreen enabled CWM with it, but the touchscreen still wouldn't work. I flashed regular CWM with it and tried to install KatKiss, but it wouldn't boot either. I tried multiple times wiping and flashing, but the touchscreen still won't work, and no rom will boot.
So now, I have given up, and for the first time in many years of rooting, roming, flashing and wiping, I have found a problem I can't figure out on my own or through Google or previous threads here, and I'm stumped. I'm actually quite surprised its taken me so long to get here. Anyway, Thanks in advance for the help!
