Hello there! I just recently purchased a second hand N1 and it seems to me that the previous owner was very fond of rooting.Anyways lets get to the point,when I turn on the wi-fi the wifi icon never appears on the top bar and the wifi flashes "scanning.." for a second and goes away. I thought that somehow the wifi chip got busted by the previous owner so to verify it I tried the Portable hotspot thing and almost every device capable of detecting wifi detects my droid as a hotspot so it seems that the wifi is there but something is amiss with the regular wifi as it doesn't my virtual adhoc router which is immediately detected by every device capable of wifi reception and yes my portable adhoc router isn't capable of anything better than b and g so there's no reason why N1 doesn't detect it. I decided to update to 2.2.1 so that all kind dubious works of previous owner would go away but the manual update also fails with an error of "assert failed: file_getprop("/system/build.prop", "ro...... Status(7)" and I noticed that the recovery thingy says "clockworkmoderecovery" which means that the device is definitely rooted and its bootloader is unlocked. Things to clarify: - yep the update(2.2.1 official) file is in the sd card and is correctly named as update.zip(common extension hide option to off so I see all the extensions) - My present phone info says Model Name : Nexus One Android Version: 2.2 Baseband version: 32.36.00.28U_4.06.00.12_7 Kernel Version: 126.96.36.199-27220-g328f560 android-build@apa26#1 Build number: FRF50 Here are the things I collected that might help: Hboot-0.35.0017 Clockworkmod Recovery v188.8.131.52 So anykind of help as to how I can get rid of this irritating blind wifi or can update to fresh official form without any unlock or root( I don't need anykind of root or unlocked bootloader options!) I am a complete noob and most of the forum posts about this kind of issue have so many suggestions and the op never returned to confirm if those methods/suggestions worked or not so I am being cautious here as this N1 is my only cellphone to go on with for the next 1.5 years and no wifi means no internet access for me as our cellphone data plans are far too expensive..but the only one that I have used in my brother's iphone is a micro sim that would be too small for N1's sim slot. Thanks for your time and understanding,I appreciate your help.
