Many N82 user have complained about the limited brightness in the Nokia N82 compared to much brighter phones like the N95 8GB. This is something that Nokia are surely aware of but have not fixed with a firmware update. Thanks to P@sco, it's clear that once again the hacking community has done what Nokia simply can't be arsed to do...
GUIDE: Download (right click, save link as) the 10200c8c.txt file HERE, then copy it to the 'others' folder on your memory card. YOU WILL NEED A HACKED PHONE. Instructions below.
If this is the first time that you'll be hacking your phone, follow these simple instructions:
1) Download and install hellocarbide from HERE, DO NOT OPEN IT YET. 2) Open Y-Browser and send it into the background by hitting the menu button. 3) Open HelloCarbide, press options and then select menu1... When the pop-up message appears just press yes. 4) Open Y browser again. 5)Copy the 10200c8c.txt file from where you've saved it to C:\Private\10202be9\. 6)Check if there's a 10200c8c.cre file in C:\Private\10202be9\Persists\, if there is one, delete it. 7)Restart your phone. If you've previously hacked your phone and have CapsOff installed, start from step #5.
Please note that after performing this hack, the only way to lower the brightness settings of your N82 is to delete or move the txt/cre files in C:\Private\10202be9
Note : As I have not any Nokia N82, it has not been tested by me. but it has been reported working.
