OSU1 and E101

Actually that doesnt work either... my x is bricked due to a faulty hdd. I changed the hdd with a working one. Could not get osu to work i then cloned the one s hdd on the same insider preview overwritten the files in the a and b folders in the x:\ drive
of the new hdd same thing happens.... still thinks the version on the nand is superior to the one on hard drive... lost 3 nights trying to figure it out. Im at the point of using a hex editor and try to change the update parameters on the a/b folder systemupdate.vxd
to trick it into thinking its a newer osu? Its really a **** move of microsoft not providing the insider preview osu to insiders. Btw i was able to remove the x from insider preview but there should be a online check for insider preview recovery if they cant
provide us with the osu to get us back going again. This is unacceptable im kot the only one and is extremley fustratng that m$ wants $100 usd for something i could fix myself in a few minutes with the right osu....

I am having the same issues with my Xbox. How can i unsubscribed from the insider program if my xbox cant even do a proper factory reset online or offline? Ugh

I am just like you in the same version some solution

LOOK IN A POS THAT ANOTHER INSIDER USER HAPPENED TO HIM THE SAME AND GET HIS COMFORT OF THE PROGRAM AND WHEN THE OSU1 ARRIVED AT THE VERCION THAT HAD PUT UPDATED

So, there is nothing to do because I am in the same frustrating situation. My Xbox was on Preview Insider and no OSU worked for me.

I an enrolled in the insider program.

Yeah. That's the point. How can unroll preview if the console keep showing E101 error

The XBOX support, Insider program FAQ is worth reading as well as the XBOX
Insiders wiki found on the Reddit Insiders Forum where all Insider issues should be posted.

1. Launch the Xbox Insider Hub on your Xbox One
   or a Windows 10 PC.
2. On the main landing page, select Settings.
3. Select Manage devices and choose the one you want to remove from the programme.
   
4. Select Done.

Note
This process typically takes about 10 minutes to complete. It might help to know the serial number or name of your previous console to ensure you remove the correct one.

As part of the removal process, your Xbox may undergo a factory refresh. If a factory refresh is required, your games and apps won’t be erased, but any profiles or system settings saved to the console will need to be restored
after the refresh is complete.
