It’s quite common for a hacked phone to not play nicely with OEM software created to interface with the devices. Notable examples include HTC Sync and Samsung Kies. When a phone is rooted and running custom firmware, these services may not read the phone properly and may not recognize the device as one that needs an update. In rare cases, they don’t even recognize the connected device as supported. Samsung Galaxy S Blaze 4G owners have been having a problem with Kies recently, and now there is a fix.
Okay, to call it a fix may be stretching it. XDA Forum Member jparnell8839 has figured out that Kies won’t recognize the phone on any stock firmware after UVLB7. So if you’re running something that came after that and want the next official update, you will run into an error where Kies claims the phone isn’t compatible with their software upgrade service. Says jparnell8839:
Finally, I thought “hmmm, it still says custom binary when im in download mode, even though I’m stock with stock recovery” so I went to sammobile and got the pre-july 16th image (UVLB7) and flashed just the tar.md5 file (no pit) made sure repartition wasnt checked, etc. in Odin
upon reboot, Kies immediately recognized there was a firmware update and pushed me up to UVLF4 (flash counter is at 4 btw). When it rebooted to download mode from Kies, it said Samsung Official binary this time
In order to be more helpful, jparnell8839 has uploaded the firmware that was used to fix this problem for others to download and use. With it, stock users can upgrade to the next update easily. For more information, go to the original thread.___________________
