The information in this post is copyrighted and may not be reposted without consent from Kerry Green or Gregory Watts. Kerry Green developed this method after weeks of testing and work. This post is now in the troubleshoot section of the Dell Database. You have a Dell Venue 5055 and have somehow bricked it, meaning it's worthless and will not boot. Recently my friend Kerry Green was asked to repair a Dell Venue that was in a non-boot loop. It would flash in a millisecond the TPM error. I looked at it and we both studied many forums, all said it was toasted. This is the error where the TPM is not allowing you to get to BIOS or install any OS. No attached keyboard, nothing will allow you in. The TPM was created to prevent a theft from reinstalling the OS and using the tablet. Well, Kerry found a way. There is a serious disclaimer from him, read it, you are seriously doing this at your own risk. Disclaimer: This repair involves advanced micro-soldering techniques. And you could run the risk of destroying your Bios chip. Perform this repair at your own risk. 1. Remove back cover and unplug the battery. 2. Remove the shield covering the processor and memory. 3. Locate the Bios chip in the smaller field under the shield. 4. The bios will be marked: Winbond 25Q64FW1G Photo 1 5. Solder a 26 or 28-gauge wire to pin 6 of the Bios chip. Photos 2 & 3 Plug the battery back in hook up a USB Keyboard, and power on the tablet. When the dell logo comes on, short the wire to pins 3,2,1 in that order while pressing F2 repeatedly. - After you have shorted all three pins, the tablet should boot into bios. 6. Once in Bios, go to Intel PTT settings in Security and turn it off. That is TPM2 settings. Photo 4 Be sure you have it set for legacy boot and not UEFI. 8. Restart tablet and reinstall OS. 9. Be sure to desolder wire and then re-assemble. Photos 5; 6 & 7 ![]()

Try shorting just the clock to ground. That is the old way to clear the bios password

Never thought of such a simple way to short. Thanks for the pin idea. I just soldered to be sure I didn't short the wrong pins

Same - tried this on an HP 800G2 that had same type of BIOS bug where the TPM chip kept rebooting the system. Seemed to keep the BIOS logo up longer the first time or too we tried. But never got INTO the BIOS. Now we don't get a logo at all and there is less USB activity. Don't know if we corrupted the bootstrap code in the flash chip or what. Frustrating that this loop keeps you from even doing a corrupted BIOS recovery. USB drive never gets accessed to flash the BIOS in recovery. Thankfully motherboard for this computer are super cheap!

Thank you so much!!!! This worked for me perfectly! I will note that I was into the BIOS after only touching Pin 6 to Pin 3, but it worked!

It really solved the rebooting loop issue of my Dell Venue 10 Pro. I'm glad I've found this site. Kudos to Dewayne Watts. I did shorted the exact spot of the Bios pin using both hands. I did a lot of practice before committing to use this method. And after that I was ready to apply this method and was very successful in resetting the Bios chip. Thank you for your tutorial Dewayne Watts.
