Recently I helped one of my friend updating his N1 to UV/OC kernel by pershoot. However we found a strange problem when the kernel image is being written to the device. I update lots of kernel before on my N1 but never encountered such issue like this. Here’s the error :
C:\Superboot>fastboot-windows flash zimage zImage sending 'zimage' (2280 KB)... OKAY writing 'zimage'... FAILED (remote: unknown fail) C:\Superboot>
Tried a few kernel variants didn’t solve the problem. I end up re-flash the ROM without wipe. Fortunately it works! Kernel update was successfully done after that.
