Hi folks. I've had my One S (running Android 4.4) since May and never had any issues until yesterday. I'd left it on charge overnight (as normal) and it'd turned itself off at some point during the night. Upon turning it on it worked for 4-5hrs albeit with a 'stuttery' touchscreen before shutting itself down again (battery was at approx 75%) so left it overnight. This morning the battery was drained completely, so left it to charge before turning it back on. Once again it worked for a few hours before reverting to bootloop. It never gets past the HTC welcome screen before shutting down and restarting over and over. At the boot menu screen, info is as follows: ***LOCKED*** VLE PVT SHIP S-ON RL HBOOT-1.13.0000 RADIO- 0.16.31501S17_2 OpenDSP-v188.8.131.52.0405 eMMC-boot Apr 20 2012, 15:14:18 FASTBOOT RECOVERY FACTORY RESET CLEAR STORAGE SIMLOCK IMAGE CRC SHOW BARCODE Tried charging it/plugging it into my laptop- Will not charge or let me access it via laptop. Doesn't seem to recognise the device at all. I have tried booting it in recovery mode, but it still wont pass the HTC welcome screen and keeps looping it. Same for fastboot, factory reset and clear storage. I'm really at a total loss of what to do. Having taken it to a local repair specialist, he states it's definitely software-related, but by allowing him to fix it my warranty would be void. So unless there's any other options I could try it's a case of waiting for HTC to be open on Monday to book it in for repair. Cheers for any help/advice. All the best!
