Guys Updated C6902 Indian
Working Fine
Will be uploading the FTF file soon on dropbox
how did you do that ? I see no update here in India. Also post the software info screenshot…
you have posted both links of Screenshots 😛 Post screenshot of software info. Dial *#*#7378423#*#* and service info > software info.
Which version of flashtool you used and post the link of ftf.
so you have any idea when will the official update roll out to india ??
no idea, still waiting. Many countries have not got it yet. Though it is updated in Sony’s respective region website.
What i think is now try to re-install firmware via PC Companion or SUS you may get the Indian version of it.
ok i will try that
thanks a lot
have you tired ? Does it work ?
in the final step of updating will let you know ASAP
No it doesnt work…still on 14.1.G.1.534 🙁
I wanted to tell that :- first flash .257 ftf for c6902 and then re install firmware via sus then do you get indian version or journalist ????
Now it will not void warranty. 100% safe. No root needed
Download ftf
Download flashtool from above
Now install flashtool
Open the location where flashtool installed, create folder “source files” now keep ftf file in this folder
Now run flashtool, click on lightnig icon, choose flashmode, select the source folder, chose the ftf file,
Uncheck the boxes of wipe data cache log
And click on to install ftf
will wait for official update for some time …..to be honest i am afraid to do that manually ….will do that if no other go
update now rolling
All links added in post with credits. Thanks a ton 🙂
update now rolling in india 🙂 via pc companion 🙂
yes we have updated the post, and already downloaded it meanwhile 🙂
do post your review on it, especially on screen quality.
yeah downloading rite now will share my thoughts soon !!! 🙂
yeah your change log is perfect .. i dont see no changes after a good three days of testing … and the camera is still not upto the mark with lot of noise in the images….it doest look like big sensor or 20.7 optics or g lens present inside and one more thing my mobie heat up so quickly ..it goes to 42 degrees with light usage and 46degrees with average usage and insane 50 degrees with heavy usage … is it only with my phone or a software issue ?? if you share your thoughts i might go for a replacement (heating issue is present before and after the update ) help me out …
take heating issue very seriously, it may be due to faulty battery. Take it to customer care. show them up. Show the heating to them with temperature. they will do software update. Let them do. Than you again show them heating and get a replacement…if it’s not a software issue. Do not agree to have faulty hardware with yourself 🙂
Nothing nothing nothing!
I just noticed that when I am on a ongoing call, try to type another phone number on the dial keypad, but the numbers are invisible, not sure if it’s the update caused the problem or not. Could u pls help me to solve this problem. Thanks a lot.
