i was registering my device yesterday and it wouldnt recognize my serial number. i also noticed the serial number on my device and on the system settings didnt match with the one on the box. so when i tried to register it to get the gps dongle it wouldnt recognize my serial so i tried to contact asus thru the live chat option bt no one would connect to me. so i just left it there and when i tried to register it today it was already registered. asus must have done it automatically. anyone else have the issue with the serial numbers not matching up?
Well it's been quite a voyage..
Got my TF201 returned from RMA yesterday, it works fabulous - let's work it with Unlock Tool.
Gives me unknown error. What could that mean? After some lurking I find my s/n is "unknown". What's that? Maybe it can't authenticate with the Asus servers? After more investigation I find various s/n unknown threads and stumble upon the Ratchet fix for this. Sure I thought.
But Ratchet required root, so first a downgrade (I used 18.104.22.168). Then hard wipe to clean the new firmware from previous garbage data.
Next use mempodroid to gain temporary root access and apply the s/n fix according to the guide.
Allright, serial number pops up in settings.
Let's try OTA and Unlock Tool to confirm success - none work.
Unlock Tool still displays "Unknown error. This may be a network connection issue. please wait and try again later.".
That seems like a short story. Well for documentation here's the howto to what was done:
