If stuck on "fireworks" screen or Bootloop....
1.Take out the two batteries (after turning off), big white and small round blue, leave out for 10 minutes. Replace blue one first, then main white one.
2. Disassemble and reseat emmc board connector.
Reseating the emmc means disassembly of the Thrive as you see in this :
Cracking Open the Toshiba Thrive - TechRepublic
Then removing the connector at either end and reseating it, after which you reassemble the Thrive.
3. Boot into recovery and try a factory reset.
Turn off tablet
Press and hold the "+" on the volume key
While continuing to hold the "+" volume key, press and hold the power button
Tablet will start (and let go of both buttons at this time) and will give your 3 Icons.* Using the volume key, select the middle Icon of the box with the arrow coming out of it.* The power button is used as the "enter" key
On the next screen, arrow down to the wipe data/user info clean and factory default and hit the power button.* PLEASE NOTE, THIS WILL WIPE OUT ALL SETTINGS AND INFORMATION YOU HAD ON THE TABLET.
On the next screen, select Yes for wiping all info and restore to factory.
Once this is done, select reboot and you will be brought to the initial set up.
4. Send a PM (private message) to dalepl or pio_masaki and ask for a reflash.
If it's not a hardware issue, this last will 'fix' it.
#3 and #4 will erase all of your content.
Now, the really, really, important part:
***WARNING.... WARNING.... WARNING... WARNING... WARNING! ***
Occasionally, there are posts by people who claim to be able to "reflash" non-functional Thrives.
For the protection of our forum members, any such messages are deleted immediately. A second post is rewarded with an immediate, permanent ban -- and I urge that no one think to test our Moderators on this.
Recently, a few individuals have done exactly that and are now on the outside looking in.
The reasons are simple:
First - TRUST. The method used by these would-be reflashers involves full remote access to your PC, with file transfers. Are you willing to turn your computer over to a brand-new forum user who has no reputation, who might infect your computer with a virus or other malware? Even if you think there are no passwords and credit card numbers to steal, malware can easily turn your PC into a "zombie" that attempts to infect other computers across the Internet and on your home network.
Second - Even if the person offering has no malicious intent, the reflash tool is dangerously powerful.
One mistake can irrevocably "brick" a Thrive, which even Toshiba can't undo without expensive hardware repair.
Are you willing to trust your Thrive to someone who may have never used the tool before, or has no responsibility for the result?
So, if, after trying the above procedures, your Thrive appears to need reflashing, please post on the forums first.
Maybe someone can help fix it without reflashing. If it turns out a reflash is needed, send a PM to dalepl and pio_masaki - nobody else.
They are recognized Developers on this forum and are trusted, professional and helpful. They have the knowledge, experience and the proper tools to do it correctly. NOBODY ELSE can make that claim.
You may be contacted via PM by another member offering "help".
They are not sanctioned by the forum owners or Staff, and DO NOT possess the knowledge, experience, trustworthiness, or, possibly, the proper tools needed, to fix the issue.
They might, in fact, do more harm than good, and the forum is in no way responsible for any damage done by them.
You could easily end up with a non-recoverable $400 brick.
If you are approached by ANY OTHER MEMBER offering this service please contact the Moderation Team IMMEDIATELY so we can take appropriate action - and before the damage is done.
Self Help now available.
Go to [TOOL] Reflashing Your AT100/105 Device When It Will Not Boot and follow the instructions EXACTLY.
Note that the forum and staff are in no way responsible for any damage done by using these tools.
Limited support will be given.
Tools may be removed at any time if requested by Toshiba.

In case you should find yourself in a boot-loop after using dalepl's Univeral Easy Flash Tool to root ICS,
follow the instructions here: If you get Bootloops after using Dalepl's Universal Easy Flash Tool (ICS ONLY)
IMPORTANT: Again, this only pertains to bootloops that occur AFTER USING THE UNIVERSAL EASY FLASH TOOL TO ROOT ICS AND ONLY ICS.
