Hi guys,I had the same problem.Check this out:
Nokia Mobile Phones Engineering Bulletin No. EB-401 / 16.04.02
UK Technical Support Level 3
Effected Product: 5510 (NPM-5)
NEW UI DSP SOFTWARE VERSION 6.1 (SERVICE LEVELS 3 AND 4)
New UI DSP software version 6.1 has been released for NPM-5.
NPM-5 UI DSP software updating is allowed only in E&A service level 3 and 4. I.e. Nokia compensates only UI DSP SW updates, which are performed in E&A service level 3 or 4.
Because UI DSP software updating operation takes totally more than 15 minutes, it is allowed to carry out only on complaints if:
A. Due to the corrupted UI, the phone switches off after couple of seconds, every time when booted
B. All memory can not be released by deleting music files
After flashing has started, don't do anything else with the PC. Key presses, mouse button clicks or running applications may disturb the flashing operation.
Changes/improvements made from version 6.0 to version 6.1:
Earlier in some cases track titles and artist names were shown wrong characters
In some special cases track titles and artist names were shown shortened
You can upload it in the nearest service centre...
I hope it's helped you on this.
