Be VERY careful and inspect your NEW battery! Mine turned out to be 1.5 mm thicker than the iPod original and guess what, I tested it out with the iPod half open, everything worked great, it fully charged and maintained the charge and when I’m about to close the iPod again…real tight fit on the upper half, I pushed more and…display got cracked; it turns out some chinese replacement batteries are just a tiny bit thicker and thus the back cover wont close properly; DO NOT FORCE IT IF YOU NOTICE IT’S OFFERING RESISTANCE! instead take that thick battery out, compare it to the original and re-order the proper size if it wont fit within the space!
Between step 12 and 13 there is no detail on how to remove the board! I did the procedure until step #12 but board is firmly attached to the case! even after pullling the metal tabs it’s still glued to the base, please help
