Oh no! Looks like your kindle wont boot! Dont worry, this thread got ya covered. Welcome to the Unbricking Station!
NOTE: I DO NOT TAKE RESPONSIBILITY IF THESE METHODS WILL MAKE YOUR DEVICE WORSE. USE AT YOUR OWN RISK.
1. I have a red screen at boot-up. What should i do?
This happens when you install the 2nd bootloader when you are on
software version 7.3.0 or higher, even though you downgraded to 7.2.3 the 7.3.0-7.X.X bootloader will retain.
SOLUTION: Flashing the 7.2.3 uboot file will do the trick by booting into fastboot with a fastboot cable and type these commands
fastboot -i 0x1949 flash bootloader kfhd7-u-boot-prod-7.2.3.bin
or if that doesnt work and you have backed-up your stock boot, recovery, and system type these
fastboot -i 0x1949 flash boot stock-boot.img
fastboot -i 0x1949 flash recovery stock-recovery.img
fastboot -i 0x1949 flash system stock-system.img
2. When i bootup it just gets stuck in the blue kindle fire logo or the bootanimation. What should i do?
This happens when you installed the 2nd bootloader successfully and you might have killed a binary during stack installation, or you might have messed with the system files of your OS.
SOLUTION: If you can boot up to TWRP (recovery), you can just flash the stock Amazon OS or CyanogenMod once again.
Booting to recovery can be done by just pressing the volume up button while in the ORANGE kindle fire logo, after that just press install and select which OS you had before the error.
Amazon OS: http://forum.xda-developers.com/showthread.php?t=2218475
CyanogenMod 10.1: http://forum.xda-developers.com/showthread.php?t=2245335
Use adb sideload, if you don't have these files on the kindle's internal storage.
Go to advanced, then to ADB Sideload.
While in your computer, go to a command prompt and type
Adb sideload *osfilename*.zip
After that, it will install itself and you are good to go!
3. When i flashed FireFireFire/broke the bootloader, it wont startup, what should I do?
You flashed a incompatible bootloader (1st Gen) on a 2nd Gen device.
SOLUTION: Your best bet is just send it back for a replacement.
If anyone have anymore methods to unbrick their device, send me a PM to get a chance for your method to be featured in this thread.
Credits to Hashcode for the bootloader and to Amazon for a wonderful device. xD
Hi all.
Im having some problems with this, and was hoping that some one here could help me.
I have unlocked my device, no problems.
Then i have installed CWM, no problems.
Now here my problems begin... I have copied a custom ROM zip file, onto my tablet. When i boot my tablet into CWM i get some errors in the bottom of the screen looking like this:
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
Now when i choose to "- Install zip from sdcard" and after that i choose "- Choose zip file from sdcard" i get this error: E:Can't mount /sdcard/
Then i try to select the "- Choose zip from internal storage" but then i get this error: E:Can't mount /emmc/
Basicly i cant do anything at all in CWM without getting errors, cant even whipe the cache or anything.
Can someone help me to find out what to do now. And hopefully how to solve this?
I can boot into my androind system without any problems.
Hope some one know's what to do. Thank you in advance.
Info:
TF300T
Android 4.2.1
Kernel 3.1.10-g6f31760
CWM-based Revovery v6.0.2.3
If there is anything else you need to know to be able to help me, please ask.
Have a good day.
CWM doesnt work with the 4.2 bootloader from ASUS. Only TWRP for bootloader 4.2 seems to work. You will have to flash TWRP 2.5.0.0-tf300t-4.2. Take note you need the TWRP version with the "-4.2" at the end. Flashing the incorrect TWRP version can brick your tablet.
Download http://techerrata.com/file/twrp2/tf300t/openrecovery-twrp-2.5.0.0-tf300t-4.2.blob.
Reboot tablet and hold volume down button while it's powering up to enter fastboot mode. Do not select any of the 3 icons (RCK, Android logo, Wipe Data) on tablet. Connect tablet to PC via USB cable.
On Windows PC, cmd window type:
fastboot -i 0x0B05 flash recovery openrecovery-twrp-2.5.0.0-tf300t-4.2.blob.
On tablet, wait until blue progress bar completely fills up.
On Windows PC, cmd window type:
fastboot reboot
That should replace your CWM with TWRP.
Hello ImmovableObject.
Thank you very much for you reply, that was excatly what was wrong.. Stupid me, not checking up on that. I actually flashed another version of TWRP, so i guess i was extreemly lucky that it did not brick my tablet.
But after i flashed the right TWRP its all good, everything is working as intented, and i can make backups and flash custom roms now. Thank you very much for your help
Have a good day all.

You are very much welcomed! I'm glad it worked for you.
I found this useful when I was struggling with CWM as well, very glad I was careful to pick the 4.2 blob
Thanks for the help!
Holy Crap!
I can't believe how stupid I was! I ahve always despised CWM yet I was using it on my TF300T. After searching and searching for a fix I came onto this. Great job man!
THANK YOU FOR THIS!! I too stumbled around with CM Recovery for about 30 minutes, dumbfounded by the fact that it couldn't mount either the internal or external storage. I did some research and that's when I came across this post. I can't believe they don't make any mention in any of the tutorials that CM Recovery won't work with the newest 4.2 bootloader from Asus.
Your method did not work with my TF300T, Please assist
@ImmovableObject , I've tried your method but for some reason my Tablet did not reboot with the command "Fastboot reboot" and i still get CWM-based Recovery v6.0.2.3 for recovery instead of TWRP. it did say the flash was OKAY.
Please Please help

That's strange.
Was your tablet running Android 4.2?
Try waiting a little longer (5 or more seconds) before issuing the "fastboot reboot" after the message that the flash was OKAY.
Things you could also try:
* Update your fastboot.exe to the latest version. You can do this via the Android SDK Manager on your computer. Fastboot is included under "Tools" > "Android SDK Platform-tools."
* Use a different USB cable.
* Connect cable to a different USB port on your computer.

Hello.
I have TG300TG that only goes to CWM-based recovery v.6.0.1.3 and can not mount sd card. I've tried the mothod described here, but I can't get to fastboot mode. When I hold vol down it only goes to CWM again and again.

I have the same problem, to actually get back to the bootloader and select RCK or Android do this:
Once CMW is loaded open command and do
adb reboot-bootloader
that also enabled fastboot again but I'm still not able to load TWRP
---------- Post added at 01:50 AM ---------- Previous post was at 01:13 AM ----------
So just like the previous few posts I too installed CWM and I can't reflash TWRP.
Here's the output from the console:
D:\Android SDK\sdk\platform-tools>fastboot -i 0x0B05 flash recovery openrecovery
-twrp-2.5.0.0-tf300t-4.2.blob
sending 'recovery' (6448 KB)...
OKAY [ 2.699s]
writing 'recovery'...
OKAY [ 2.254s]
finished. total time: 4.955s
D:\Android SDK\sdk\platform-tools>fastboot devices
???????????? fastboot
D:\Android SDK\sdk\platform-tools>
Device is unresponsive to any commands and must be rebooted manually. Once I reboot the device loads to the CWM Recovery unless I run "adb reboot-bootloader" and then I can choose to boot the ROM. So at least it's not bricked.
Fix
Found this posted by buster.
So if you're TF300T is booting directly to recovery and you can't get to fastboot do what I post above:
1. Let recovery load
2. With recovery loaded you can now use adb. enter: adb reboot-bootloader
3. You should now be at the bootloader screen (RCK, Android, Wipe screen). Do this:

Here how i restored my TF300T JB
download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
(the folowing i did at least 10 times already but didn't erase misc)
fastboot -i 0x0B05 erase system
fastboot -i 0x0B05 erase recovery
fastboot -i 0x0B05 erase userdata
fastboot -i 0x0B05 erase boot
fastboot -i 0x0B05 erase misc
fastboot -i 0x0B05 erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob) ((also this was the first time i saw the loading bar while flashing)*
fastboot -i 0x0B05 reboot
* it also took a lot longer as it should:
C:\>fastboot -i 0x0B05 flash system c:\adb\TF300t\blob
erasing 'system'...
OKAY [ 1.695s]
sending 'system' (800935 KB)...
OKAY [133.121s]
writing 'system'...
OKAY [153.973s]
finished. total time: 288.789s
im now setting my tab up to get back to CM (which initially caused this sh1theap due to autoupdate error, same as my A700 got bricked )
hope i could help you out!

twpr is working
flashed twpr v2.5.0.0
works great so far, but it takes a little more time to load than cwm.
help!
right guys, I'm completely green when it comes to stuff like this so apologies if my questions are too daft.
I tried to root my tablet and forgot to back it up, tired few things I found online and got myself in a position where I can't use fastboot as my tablet is taking me to CWM recovery straight away and holding volume key and power makes no difference... any ideas? apart from throwing my table in a bin?
Hello,
maybe someone can help me before sending my TF300TG to asus service..
I recently unlocked bootloader, (4.2.1 10.6.2.11) then flashed TWRP 2.5.0.0.
Unfortunately the TWRP was unusable because could not access any file (sd card, internal or external).
Trying this and that i wiped data... now it only boots directly into the unusable TWRP...
I'm not able any more to acces Fastboot.... drive is not found.. so i'm totally stuck
any suggestions?
Thanks
No Ideas? Anybody?
I'm afraid I will need to substitute Motherboard, the problem is that it's very hard to find one for TF300TG...
looking around (with much difficulty) I found that the part code is 90R-OK0JMB30000W (different from the board of TF300) but cannot find it anywhere.
- Asus official spares channel sells it for 189+vat + delivery
- Asus support substitutes it for 150€ + work?+shipment? (I looked around but support didn't reply to me yet)
Anyone has a TF300TG broken to sell as spares?
Thanks
SOLVED!!!!
Managed to revive following instructions below!!!

My pad was booting directly in TWRP 2.5.0.0 with touch working but no files could be found or folder/drive mounted.
I installed Google drivers as described and my windows 7 64bit finally found the pad (could hear noise as when inserting USB devices).
then run:
adb reboot bootloader
and I finally could reach the screen wit 3 icons and run all the other commands:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob)
fastboot -i 0x0B05 reboot
CHEERS!!!

Get back to bootloader (3 icons) and then try this command on your computer:
fastboot devices
if it will detect anything then you can try erease procedure by @Buster99 :
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
then after clean memory flash fresh official JB downloaded from asus website (unzip file untill you will have file called "blob")
fastboot -i 0x0b05 flash system path_to_blob
example:
fastboot -i 0x0b05 flash system c:\android\blob
this would take like 5 minutes, then:
fastboot -i 0x0b05 reboot
and you should be back on stock
I had slightly different issue - TWRP flash failed and I had only android booting - even after manually flashing recovery again via fastboot
this clean swipe got me going again - upgraded to 5.1.1 and set it up again

Hi,
Device is: Asus Zenfone 2, Z008
At some point I managed to brick it. Restored it using xFstk and some fastboot magic.
Now, the big issue is, I cannot boot to recovery.
I can load bootloader (do fastboot commands), chose "Recovery", but it will just boot normal into the OS. Droid with hazard doesn't appear, just normal boot.
Tried (not all at once)
fastboot erase cache
fastboot format cache
installing twrp
flashing stock recovery.img
No joy.
What am I missing?
Video on Youtube with the issue: https://www.youtube.com/watch?v=ESnxjGDKwWA
Hi !
A quick answer has been provided here https://forum.xda-developers.com/showpost.php?p=71063211&postcount=598
Try this command after placing this recovery img into the adb folder and boot into bootloader
fastboot devices
enter
(check if it is recognised) then
fastboot boot recovery.img
( where recovery.img should be the exact name of your recovery you want to boot into)
Keep an eye on that thread you already have posted , more users may have replied
Good luck !
