Pic of Dead Droid with ! after firmware update attempt

[SirDevan]

I recently got my TF701T back from repairs and they of course factory reset it (they put a new battery in). We all know it needs factory reset for that right? Anyways. I do a check for updates and nothing. I know I was running 4.4 previously but updater says no updates and stuck on original. So I start reading and download the latest US 4.4 firmware directly from ASUS, unzip it and put in main directory (verified mine was US) and reboot. Says all is fine, would I like to update, yes, reboot and I get the Android gear guy for about 10 minutes then it reboots. He shows up again and dead android shows up.

Now it just loops forever to this. I spent about 5 hours reading forums here, attempted a restore, but 1. the recovery.img link is bad and 2. my tablet isn't rooted.

Any suggestions? I can access the fastboot screen that gives me "RCK, Android and "Wipe Data". I tried Wipe data 3 times, no good still getting dead guy. I tried copying the latestest zip file to an sd card with boot.img and blob and file and ran RCK and it says match then reboots then dead guy again...

the fastboot screen says "released by: "US_epad-10.14.1.45-20131014" which I believe is the original.

You did a good job on your research. What might have tripped you up could be just a bad download. Files do get corrupted during download once in a while.
The recovery seems to have initially recognized the digital signature of the update file and started to flash it. And then something went wrong....
Download the firmware again. Unzip it once (the result should be a ....user.zip) and place that file onto a microSD formatted fat32 and not into any folder on the card. Boot to recovery (RCK).
If that does not work, try to rename the ...user.zip on the microSD to T4_SDUPDATE.zip and boot to recovery and report back.
Good luck!

So, I had downloaded 3 different versions multiple times before with zero success. But, once I took one and renamed it to T4_SDUPDATE.zip bam!

You just so made my day!

Thank you! Thank you! Thank you!

I have a question along these lines. What is the difference between the software update and firmware update and when do you do each? I understand the difference between what they are I suppose just not sure if updating is the same. Should I update kernel too or is that updated in an SW or FW update?

Thanks

Anyone?

I have seen these terms used very differently on different device forums.
Here on the Asus tablet forums people mostly talk about firmware when they mean the whole stock package. The stock firmware always comes with everything: Bootloader, recovery, rom and kernel
On the HTC M8 forum for example, they make a clear distinction: Software is rom and kernel, firmware is bootloader, radios, baseband etc.
The recovery seems to fall somewhere in between

Your bootloader version determines everything else. You should only flash a recovery, kernel or rom compatible with that particular bootloader.
You can, or have to, update it if you want to run a rom that requires a later or newer bootloader. Asus encrypts their BLs, so bootloader updates can only come from them - so far only with the release of a new version of the OEM "firmware".
If you as an unlocked, custom rom'd user then want to install a rom based on that new firmware, you have to update the bootloader and possibly but not necessarily your recovery before flashing the new custom rom.
Custom recoveries get more frequent updates. CWM, TWRP or some enterprising dev release new versions every few months. Always make sure it is compatible with your bootloader and rom. In most cases you can easily skip a few versions. But if you update your rom, let's say, from JB to Lollipop you should also update your recovery.
The kernel is considered to be part of the rom. At least every rom I know of comes with a kernel, some even with several to choose from. And it is a popular sport to try the same rom with different kernels.
You update the rom whenever the developer releases a new, updated version - or not if you're happy with what you got.
The safest place to be is always up-to-date: The latest roms usually require the latest bootloader and it's best to run both with the latest recovery.

If you have a working combo you can stick with it for years if you like.
But if you've been away for a while, did not follow the latest development, and want to update, you always have to:
Check if your bootloader is still current. If not, update it
Update your recovery
Wipe data, cache and Dalvik
Flash the new rom.

Nice explanation, I knew all of this but there is no way I could have explained it.
