Ever since I updated to DK28 (loong time ago) I noticed that my device become unrooted, and the USB is not recognized (already tried different cables, different PC, different OS) none of the OS even recognize that there is a device inserted to the PC eventhough on Epic, the USB menu appeared. Searching at the device manager and no new device recognized at all.
I tried to use Epic's stock recovery to flash any kind of ROM: stock ROM full, stock ROM update, but always give me errors: status 2 error and or verification failed.
My Epic is still working, however, I cannot do anything with it anymore. Cannot root, cannot update, etc, etc.
I need more advice on alternative solutions that I can use.
TIA
Have you tried the update.zip samsung had posted for the "mac users"? That could update yu to EB13, no root.
Do a search on the forum, I know you can find it.

I tried to load old stock of LG E400, however, it gave me some error at final stages. Now, the phone is working except two issues:
1: The USB is not working at all, neither for charging not for data transfer i.e. the phone is not detected on computer.
2: The graphics are not good as it should be. I guess its operating at 8bits or so.
I tried Voume Down, Home key and power, but no help by resetting it to default.
I tried Volume Up, Home and power, but i don't know how to proceed once it shows notice screen. I am not sure how to proceed or restore a new stock ROM or load a custom ROM since the recovery is not installed nor the device is rooted.
The current ROM is V10b.
Please help!

graphic error is sometimes because of firmware incompatibility with new released phone if im not mistaken
about your phone not detected
have you ever tried to uninstall the driver then reinstall and make sure that you enable usb debbuging
and if the debbuging works then i suggest you upgrade to other latest firmware because v10b is too old
Thank you for replying. I did tried uninstalling and installing, it did not help. However, I tried flashing 10E and it helped in fixing the USB issues. However, my graphics still not fixed, even i tried installing a custom ROM but still graphics are not fixed
EDIT: V10F fixed the graphics problem in the stock ROM however, in the custom Rom, its still not working. Trying V10H stockrom and trying to install the custom ROM to verify.

@amjadakmal, what error did you receive in the final stage of KDZ-Flasher?
What version of KDZ-Flasher are you using?
I have a kingston microduo3 that is supported by G2 and worked fine! Suddenly one day stop working i did nothing that affects it. I install all apps on playstore to fix the problem but nothing worked. i tried usb on other phones and works fine. Mine is even not appears that usb connected. i have cloudyG2 2.2 , twrp recovery 2.8.6.1 and DOrinmax 10.1 kernel. Plz HELP
I either have to be really stupid or brave to flash a off-model ROM for my device. The ROM was Lineage 14.1 intended for Note 3 SM-N9005, but I tried it anyway. And it works. Everything works fine as well as flashed GApps for Nougat 7.1. But the only thing refuses to work is my USB port.
The phone was running so low on battery so I tried plugging in, but it did not trigger OS's charging status. Though it does charge, I found out later. I turned off my phone and let it sit there plugging into the wall and later on reboot to realize battery does go up. But charging is still not recognized. PC does not recognize the phone either ( and therefore adb doesnt work/recognize the device ).
Some research I had lead to the stock kernel its having. What should I do now? Flashing a new kernel? What should I flash? Is there even a custom kernel for this phone and supports Nougat 7.1? Because all i could find on the internet are kernels for Android lolipop and Kitkat.
See development thread for kernels .Read roms thread .

The custom ROM were Trader418's. Somehow if the kernel doesnt work at all, it would have got bootloop. But it works perfectly fine. Just exclude the derpy USB port that refuses to show its charging.
Synergy kernel problem
I installed resurrection remix nougat in note 3. It works fine but when I install synergy kernel I face bootloop problems. Kindly help me to fix
Hello everyone!
I swapped out my USB connection to my phone because it broke and since then I cannot use any of the USB features on my phone beside slow charging (china quality).
But I tried to call my emergency number and it didn't connect me because of a bug with custom rom and the phone app. Now I'm trying to reinstall my phone to stock but I can't do it because I can't get fastboot to work or ADB.
Is there a way I can flash the stock rom with twrp? It doesn't seem to work with google's own .zip files.
Thanks in advance!
Grab a near stock ROM like SuperXE or Pure Nexus.
use http://portal.pushbullet.com/ to push the files too the device, and wipe appropriately in TWRP.
