Something interesting happened to my Cha Cha and I wanted to tell you about it.
I bought it about two months ago from Istanbul, Turkey where I live. But it was a product produced for Romania. (There were no sale from the legal distributor at the time) It was an unopened box and I opened it for the first time.
I bought it as my secondary phone. (Primary is a sgsII)
The first thing I did with the cha cha was to try to root it to be able to use "Market Enabler" (Paid market apps cant be used here). And after some XDA research I realized that my phone was S-ON (I'm 100% sure) and I had to find an XTC Clip to be able to root it. I search for it at the local GSM services etc. but could not find.
The firmware was 1.12.xxxx
A couple of weeks later, I found the battery life insufficent and search for a newer firmware thinking they could be manage to extend the battery life.
I found an Asian firmware RUU_Chacha_hTC_Asia_TW_1.25.709.1_Radio_126.96.36.199 033H_188.8.131.52_2_release_199798_signed.exe and installed it.
Then a couple of days later I found a European firmware RUU_Chacha_HTC_Europe_1.33.401.1_Radio_184.108.40.206 33H_220.127.116.11_2_release_204385_signed.exe and installed it to get rid of the Asian apps that I dont need.
Then today, I learnt that 1.52 OTA update is ready at XDA. To install it I turn the phone in recovery mode and I saw that it was S-OFF .
I have no idea how it happened but I wrote everything I did above.
By the way , After seeing it S-OFF, I've rooted the Cha Cha using the excellent tutorial prepared at XDA. And I installed Market Enabler.....
How could it be?
