[Completed] Need help please

okay so my Samsung tab3 lite was rooted but I did something and now it is stuck in CWM-based Recovery v6.0.4.8 and I have the basic android ROM downloaded on my computer and not sure how to fix this problem Is it possible for me to put the ROM on my sd card then install zip on my tablet? I have tired odin but it can never find my ROM
Any help would be amazing!

Hi, thank you for using XDA Assist. You are on the right track to Odin the stock firmware to get your device working again. But you need the stock firmware, not a rom zip. If you've downloaded the stock firmware it does download in a zip format but you need to extract that so you end up with a .tar.md5 file. Use that in Odin. Also see this, http://forum.xda-developers.com/galaxy-tab-3. It's the forum for the tab 3 and does have some information for the lite version.

I have downloaded the firmware but odin does not see the firmware at all not sure what I am doing wrong but could I put the firmware on my sd card then put it in my tablet and install zip?

Have you extracted the firmware zip? Use winrar or 7-zip. You need to use a .tar.md5 file in Odin. That's what you'll get if you extract the stock firmware .zip. Use that in the PDA or AP slot in Odin, depending on what version of Odin you're using. See this, http://forum.xda-developers.com/gal...08-2013-odin-3-09-odin-1-85-versions-t2189539

I got the md5 file and got it in odin and clicked start and then a couple minutes later it said failed and now my tablet only says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & Try again" so I went to kies and went to Emergency Firmware Recovery tab under tools but it can not find my device

OK, XDA Assist is a forum to point you in the right direction and not to solve your issue. So I'd ask here, http://forum.xda-developers.com/galaxy-tab-3/help. But use the usb ports in the back of your computer, 2.0 and not 3.0, and try different usb cables. Odin can be finicky.

Help please! :(

Guys, I really need help. I have the international galaxy s6. SM-g920I. I have rooted it already, then I tried flashing a recovery. Now it is stuck in the Samsung logo. I can still go to the download mode. Can anyone please help me on what to do. And if I need to download the firmware file, can you tell me what the baseband is? This is urgent.  I can enter download mode, but not recovery. Only have access to Odin mode right now.

To unbrick, install the stock firmware using Odin.

If you open the link I shared here, you can scroll down and see your model. That will give you the firmware.
Just follow the tutorial given in the thread.

Sorry if this is the wrong place for this. I've acquired a Sonim XP8 (AT&T) which has a bootloop issue. From Google, I've found the firmware I need (I thnk), however, I cannot find what program I need to flash it.
Does anyone have any tips/tutorials how on to flash the firmware on this phone?

Is that firmwave file a .zip file?

Looks so.
To flash the .ZIP-file you use QFIL ( read: Qualcom Flash Image Tool ).
