XiaoMi 1 Upgrade 2.3.5 to v4 problem


May 20, 2014
I have a XiaoMi 1. I don't think it's a M1S. Not sure how to tell.

The system was on 2.3.5i. I could not update from within the settings.

I followed the tutorials on these links:

I can read some of the Chinese. I used the Chinese site to download the v4 ROMs. It should be in the first 3 links. I chose the 2nd link, stable version of v4.

I tried updating through the Recovery using update.zip. It was ok wiping all data, installing update.zip. Rebooting to system one would end me up back into Recovery.

I then tried using the Fastboot method. My Fastboot screen did not look like the ones that were on the 2 links I posted above. It had the bunny with the android robot but on the top it had "Power up reason USBCHG. Enter Fastboot reason KEY PRESS." I kept getting errors during the flash. Error saying Unspecified Error... size too large. I remember having my Windows 7 drivers not installed properly when I went into Fastboot. Could that be the problem?

Also where on xiaomi.eu can I find v4 roms for XiaoMi 1?

Thank you.
