You have no need to lock it ever. The only way you will be able to lock it safely is if you returned to a 100% stock firmware and kernel. Again, you have no need to lock it.

Here are some pics of the cable I made today. I used an htc usb sync cable that came with my htc EVO. What I did was used a utility knife to cut the rubber housing at the micro usb end. 1 straight cut down the entire housing, and it will spread apart and peel off. Underneath, where the wires are soldered to the connector, is covered in a clear epoxy. I cut and peeled away at the epoxy until the soldering points were exposed. There are 5 pins exposed off of the back of the connector. 4 of the 5 are used. The unused pin is pin number 4. I soldered a wire to this pin, then further down the cable stripped off the shielding and soldered this wire to the red +5v wire. Tested connections for continuity with a digital multimeter, then tested again when connected to a power source for +5v on pin 1 and 4. After testing, I taped up the wire with electrical tape and thats it.

first try to go in fastboot mode

Push Power + Vol up
after the moto sign is on the screen push vol down

If your Xoom goes into fastboot mode and will recognized by your PC than you dont need that cable.

I believe you have to hold Volume it down for like 20 seconds or so.

Hello Guys,

I stayed silent the last couple of days because I bricked my Xoom Wifi US Version. I tried to relock the device because I did want to install the 3.1 update.

So as I went back to stock images and in the second last step relocked the device it got stock after a reboot. It showed 0x0004 starting RSD Mode or if did hold volume down during startup starting fastboot support. Regardless of the mode, it wasnt recognized from my PC.

There was no solution to find to recover from that.

xxxxx
Solution:
-> Grab a cup of coffee
-> get a micro usb cable and soldering tools
-> open wikipedia page: Universal Serial Bus - Wikipedia, the free encyclopedia
What you need to do is to solder a Motorola factory repair cable. On the Micro USB Port there is a unused pin (PIN 4) this pin needs to be connected to Pwr (usually the red USB wire). After that connect the Xoom with that cable and the Powercable plugged to your PC.
Then start fastboot and type fastboot unlock bootloader.
Thats it you finally resolved the Stuck in RSD Mode 0x0002 or 4 issue.

Shouldnt take more then 10min if you have soldering skills.

If you have any questions please dont hesitate to ask.

Best regards from Germany,
Rotesmofa



Cable should look anything like this:

I used the cable of my old Galaxy S, it is very easy because it has a little PCB inside which makes soldering a charme!

Hey Rotesmofa, I have a question out of this topic. Is the special cable you made able to charge the battery through USB hub? Thanks!

Thanks so much guys!! This saved my MZ601 (3G UK Xoom model) today when I tried relocking the bootloader which bricked it.
