[Galaxy Tab 3 Q&A, Help & Troubleshooting] yamyamR:
Hello together,

I am new here because I don't like to separate myself from my above-mentioned "Darling" ;)

Device: Samsung Galaxy Tab 3 8.0 (SM-T310)

Kernel: 3.0.31-2387075

Buildnmb: KOT49H.T310XXSBQB2

TWRP Version: 2.6.0.0

Downloaded ROM: lineage-14.1-20220709-UNOFFICIAL-lt01wifi.zip

From: https://sourceforge.net/projects/retiredtab/files/SM-T310/14.1/

(The same problem described below also happens with various others from: https://androidfilehost.com/?w= files&flid=140575 )

Rooting and installation of TWRP as with: https://xdaforums.com/t/root-the-samsung-galaxy-tab-3-0-install-custom-covery.2525630/

My problem:

The installation of a ROM does not succeed - log file below (line 300):

1. Why is it determined: "This device is tab8wifi", although it is the above.

2. To: "Cannot Find File /external_sdcard/Lineage-14.1-20220709-unofficial-lt01wifi.zip.MD5

Skipping MD5 Check: No MD5 File Found "

I deactivated the MD5 verification. The MD5 is always specified on the download pages - do I have to do something?

Thank you in advance for your help!
