- If it is indeed the i537, I can guarantee he did not flash a custom ROM. The i537 has a locked bootloader which means no custom recovery and no custom ROMs. However there is the ability to use TouchWiz-based ROMs, if you want to learn more about this and how it works read about SafeStrap.
- We do not have official 4.2.2 stock firmware available to flash. We have a pre-release of 4.2.2, a pre-release of 4.3, official 4.3, and an OTA to go from 4.3 to 4.4.2. You can read more about the different firmwares in the i537 Firmware Thread.
- Flashing firmware with Odin will erase your SIM unlock, but you can either enter the unlock code again or there are other methods that can be used. I'm not familiar with SIM unlocking so you'll have to do a little searching.
You never mentioned what you're sending the phone in for. I would try flashing the MF1 firmware first to see if it's a software issue. If it's a hardware issue then unfortunately you'll have to send it in.
Thank you for the quick response. I edited the first post to add more details but you must've already quoted me before I hit send.
Basically the problem is the screen will randomly detect 1, 3 or 5 nonexistent touches across the center of the screen (confirmed by enabling "show touches" in the developer options). While this is happening the touchscreen becomes unusable, rebooting several times will eventually fix it but the problem comes back randomly, sometime within a couple minutes and sometimes after several hours.
I did confirm my device is running MF3 and it is absolutely a i537. I'm using the phone on straight talk not ATT so I have not received any OTA updates beyond this point.
So,anyhow I understand I can fix the device status:custom with triangleaway but I don't understand why there is no KNOX counter in ODIN mode and how this may effect my warranty.
Also, if I did ODIN to 4.3 or 4.4 would this trip the knox counter? (Assuming it isnt tripped already).
Thanks for your input, truly appreciated!
