Dear friends,

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_47.17.35.3 033H_7.48.35.14_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_47.17.35.30 33H_7.48.35.14_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?

Thank you....

I am also very curious about it.

If one of the S-On Cha Cha owners can try installing those firmwares I will be happy too.

Thanks...

OK, I've got the collection of files.
Now... to be clear and not to mess everything.
My ChaCha is S-ON unbranded stock one with 1.18 bought in polish Orange
I have both windows & linux so what is the best method to apply updates mentioned above? Thank you in advance.

I used only the RUU exe files. No patch or something like that.

I was on 1.12xxxx firmware. Unfortunately I don't remember the exact code.

I used the ruu exe files I mentioned above. But I can't find the download links.
I wrote the exact file names. I think all the downlads with the same name will be the same files.

My phone was unbranded at the begining obviously.

I am very sorry that I can't provide more info.
