For #5, do we select RCK or something else? When I select RCK and push vol+ twice, I just get the bootloader issue 0x00000000.

when u select RCK does the green Light glow keep on Blinking or not?
Are you using unlocked boot loader??

When I select RCK the blinking stops.
My tablet says in the upper left corner that my device is unlocked.

What problem exactly are you facing?? Can you boot into android??
Do u have CWM recovery or TWRP??
Did u follow all steps?? r u using the same SKU as u r tablet??

The problem I am facing is that I do not have a recovery working. I cannot access recovery at all. I was trying to update the tablet by downloading the official firmware and placing it on the root of the sdcard. But it wont recognize the update when in Android. (I can boot into Android.)

HI
I think then try to re flash your recovery first using fast bot method...then try this guide again..
or the last option is send to ASUS..:silly::silly::silly:

Is this method work with every firmware, and is it work on me301t?

After Update 7-29-13
Similar problem 300t does'nt go past the asus startup screen, when i tried to do a wipe and restore it just goes back to the asus load screen (with spinning circle)and sits and spins, so then I tried reinstalling from micro sd card using the trick where u rename the file to EP201 after trying to reinstall the newest version and an earlier version from the microsd and got the dead android (same results for both )and when I use recovery I get the android guy and loading bar and he fall over dead with error, but when turning it back on, everything goes back to the stuck loading screen. If you connect the tablet to a pc it says usb driver install failed and if you try to force driver install through device manager, the driver install completes but then says the device cannot start. asus sync does not see it , I want to try to put the ep201 file in the SDCARD folder in the internal sdcard but cannot perform this because the pc cannot see the tablet. any help or suggestions would be appreciated.The un rooted tablet Was running 4.2 just fine before i tried the new ota update 7-29-2013 and thats when this happened , I tried to call Asus, since my warrenty had expired last month they said they would fix it , but it would cost me .....i explained that their update is what made it unusable, but they didnt say anything about that fact. and told me the same .... if you have a idea or have solved the same issue PLEASE post
Thanks

[Q] HTC Desire down, stuck at the HTC boot screen after bad update

Hi everyone,
Let's go straight to the point here's what took my phone down :
I had HTC Desire that I rooted with unrevoked. A several days ago I was notified that a new OTA update (the 2.29.405.2 version, the 28.89MB zip file) was available, so I downloaded it and tried to install it. The update wouldn't install as my phone was rooted. I found on some forum some guy that said he had the same problem and managed to install the update by renaming the zip file update.zip and moving it to the root of the SD card so this is what I did.
Now my phone is stuck at the HTC white boot screen, keeps rebooting. When I boot it in recovery mode it displays an error message (see attached file) like :
SD cheking....
Loading...[PB99DIAG.zip]
No image!
Loading...[PB99DIAG.nbh]
No image or wrong image!
Loading...[PB99IMG.zip]
No image!
Loading...[PB99IMG.nbh]
No image or wrong image!
I'm really new to all this and any help is more than welcome!
Well as far as I can see that's not an error message, since I get the same messages when booting into my Recovery mode on Nexus One (and mine is working).
Did you try wiping the phone and / or flashing your previous ROM again?
Thx for your reply.
Yeah I tried factory resetting it. To flash a ROM do I need to have a working phone, or just a working bootloader ? And how do I know my bootloader is still working ?
From what I understood the bootloader is the menu you get in when pressing [Volume down] while turning your phone on. If so, I do have a working bootloader, and the last (but not least) thing I need to be working is a recovery.
So I tried to re-install unrevoked while running Linux, but Linux doesn't recognize the device. I'll give it another try while running windows since it recognizes the phone if it's in recovery mode.
In case it doesn't work, is there anything else I can try besides sending the phone back to HTC ?

The same thing happened to me several weeks ago while working on some settings and updates. I freaked out a lot, but this is what worked for me. It may work for you:
1. Remove the battery from the handset
2. Press & hold the power button on the handset for 10 seconds
3. Re-insert the battery
4. Press your volume down/up button (depending on what device you have) and while holding it, press the Power button.
I would suggest making a Nand Backup once you're in the HBOOT screen, but before you do it, chose the USB-PC Toggle option so that you can go into your phone via Windows Explorer and remove any flashable zip file your SD may have other than the ROM you want to flash.
what happend when you enter the recovery menu by selecting it with volum button and then power button to enter ? does it reboot into a green menu called clockworkmod ?
did you ever download a custom rom, such as for example defrost.zip and copy the file without unzipping it to your sd card, then select wipe all stuff you have and install that rom (zip) file. did you do that ?
i am also new to it and i have the same phone as you, but all works great for me, just needed to read many posts and tutorials here, then i did it and i am happy with it.

It enters a menu with 4 items :
FASTBOOT
RECOVERY
CLEAR STORAGE
SIM LOCK
Then when I select RECOVERY it enters the HTC boot screen endless loop...
I tried using unrevoked but it didn't work, then I tried using a RUU but it didn't work either.
I'm kinda loosing hope here any other idea what I can try?
SOLVED
It's alright I managed to run a RUU while the phone was in the fastboot submenu of the HBOOT
well I got the same problem.
Is there a real solution to it?
entering in nandroid just wont work.
As I said running a RUU worked, even though it wiped all the data off the phone.

[Q] Bricked transformer TF101 :(

hello, i just tried flashing this rom
http://forum.xda-developers.com/showthread.php?t=1245892
followed all his instructions, but now the device is stuck on asus boot screen.
and i forgot backup ! (Zzzz)
i can boot in to recovery mode, computer recoginse device but there is error saying
driver isnt install. but i tried driver from asus website to manual install but still error!
- tablet cant mount to computer
- i think i just make it worse... somehow it just boot into recovery mode only ! (recovery loop)
- and now cant shut down , when i shut down it will just boot back to recovery mode
have you tried the cold booting from linux option?
volume down + power
wait til message appears at the top of the screen then release both buttons
wait for a few seconds
you will now have 2 options
select cold boot
if that doesnt work try using brks tool and try getting the external recovery onto your tf with the backup and root option. The tf needs to be in apx mode, although your pc will still not recognise it, it should still flash the recovery for you. After that you need to get a rom downloaded onto an extrnal micro sd and flash it.
Unfortunately you will need to use the cold boot method from now on as normal reboot will not work.
It will let you atleast get a working TF again.....to an extent.
DO NOT be tempted to flash the "touch recovery" from brks tool as this is for internal card only.
Can i just suggest to anyone reading this: always have a known to be working rom.zip stored on your internal and micro sd just as a precaution or atleast download and store a couple of roms on the internal - at least one of them "should" work and wont all be bad downloads.

yes i have tried cold boot, but it just stay on the same screen, so i think the rom may be malfunction in copy process
i will try the other method you suggest thankyou
yay got it back to stock ! thankyou for your help
what did you do to resolve your problems?
i used the brks tool to go into apx mode and then use stock rom from asus website and used their tool to flash stock. Now i successfully rooted and applied rom ! all working now

[SOLVED] Bricked my Transformer....

Hi all,
I had my Transformer up and running on CM10 when I decided to give Asus JB a try this morning. As a preparation I tried to switch from TWRP to CWM. So I followed the instructions here using dd in a terminal on my tablet. After this I tried rebooting into recovery (Power + VolDown).
But I didn't work, it took me directly to a message saying "OS will cold boot in 10 Seconds if the selected mode is not confirmed". I had the choice between wiping and fastboot.
So I went into fastboot and tried to reinstall TWRP using fastboot. This worked withoud errors but after a reboot to recovery I got the same problem. When I choosed wipe date the splash screen from TWRP came up for a few seconds and then it disappeared and I shows me some lines telling me that it wiped my data - and then the device reboots.
A normal reboot led me to a screeen showing the ASUS Logo and the "The device is UnLocked" in the upper left corner. And nothing more happens...
So tried to reinstall CWM using fastpath which also worked without problems. After reboot still no direct access to CWM, had to go through wipe-data again and then it jumped into CWM. I installed several different Images with CWM but none of them solved that problem. The device still istn't able to boot into OS or direct into CWM.
I also tried to flash the blob file from stock firmware using fastboot, but after the transfer ended and it startet to flash it stopped with an red line saying an error occured.
Now I'm running out of ideas how to solve this problem. Any ideas?

ok,let me put it this way,did you ever upgraded to 9.4.5.30 firmware?
No, not before my tablet got bricked. I tried to recover with a stock Rom afterwards and accidentally downloaded and flashed .30 instead of .26
Maybe this makes things worse but the problem is not caused by that.
Btw: thank your for your support

Did you used NvFlash tool while you were on .26?Anyway you should come here on irc --> http://webchat.freenode.net/?channels=asus-transformer <--- it's easier to chat than here on forum.
No, I stupid idiot did not make a backup with nvflash.
I really appreciate your support but unfortunately I'm not at home anymore so I can't chat for the next hours.

Have you try this :
Code:
*** Factory Restore after a softbrick/Downgrade from Jelly Bean to ICS/Clean Factory Restore ***
When You Need This?
* if you get stuck on Asus boot screen (the one with the spinning wheel)
* If you don't like JB and you want ICS back
* if you want to get back to a clean stock firmware
Note: You need to have a working recovery (stock or custom) in order to use this method.
========= Recover /Downgrade from Jelly Bean to ICS/Clean Factory Restore with stock recovery =========
1) Download the latest firmware from Asus site (based os your SKU,eg. ww 9.4.5.26 * to downgrade from Jelly Bean you need the 9.4.5.30 firmware)
2) Extract the .zip file somewere on your desktop (the result will be another .zip file,use it for step 3)
3) Rename the extracted archive to "EP201_768_SDUPDATE" (without the " ") and upload it to a MicroSD card
4) Insert the MicroSD card in your tablet and use this button combination to Power ON and go to recovery --> Start the tablet by pressing Volume Down and POWER togheter for 5 seconds ,a message will inform you that you have 5 seconds to enter the recovery,press Volume UP before the 5 seconds expire.
At this point the device will go in recovery and should start updating your firmware .

Yes. I tried this but it does not work. When I start with pressing Power and VolumeDown the system only lets me choose between wipe data and fastboot mode. It does not recognize any system update files
Problem solved...
Hi,
just to let you know I solved my problem. After trying a lot of different possible solutions described in a lot of threads nothing worked for me. Finally I flashed JellyBean through CWM from external SD Card. This did not change anything but after booting into fastboot mode I installed the kernel blob extracted from a zip file found here by using
Code:
fastboot -i 0x0b05 flash boot blob
And that's it.... after 10 hours of try and error I finally got my device up and running again....

[Q] Soft Bricked Tf300TL locked bootloader

Thank You!
