crwdns2890332:0Drained battery, iPhone overheatingcrwdne2890332:0You have a major issue with the phone, most likely on the logic board. There is a slight possibility that it is a battery issue but overheating is usually related to a short of some kind on the logic board. Unless you have the skills or tools to troubleshoot this, you would be better off to have it looked at by a reputable repair shop that does some micro-soldering.
crwdns2890332:0Chip solder ball sizescrwdne2890332:0When it comes to reballing IC’s in iPhones/iPads or other smartphones, a solder paste and appropriate stencil is the best way forward. There are plenty of Youtube videos on how to reball IC’s using this technique. I do have an assortment of solder balls, ranging from 0.2mm up to 0.8mm that I use occasionally if only one ball is muffed up. IC’s have different pitches and sizes so you need to have a wide assortment. Those reballing large CPU’s, for example on gaming consoles, will prefer to use solder balls.
crwdns2890332:0Why is my iPad mini 4 rebooting after battery replacementcrwdne2890332:0It could be a bad replacement battery. If the original battery was still usable, I would re-install it to see if the problem is consistent with the board or the battery. However, the symptoms look more like the battery SWI line was damaged. Look for damage in the area surrounding the battery connector. Sometimes components get damaged when lifting the connector and some of those connectors allow the battery to communicate it’s charge state to the CPU. When they are damaged or missing, the device behaves just like yours.
crwdns2890332:0Battery replacement NFC scrapedcrwdne2890332:0I don’t think this is problematic. The coil doesn’t seem affected but the picture is too blurry to say for certain. You don’t need to tape it up unless the coil is exposed.
crwdns2890332:0Are iFixit screens weaker?crwdne2890332:0Which screen did you purchase? iFixit, like all vendors, offers various screen quality levels. You can get a used original screen which will be an original screen pulled from another device or you can get the regular screens which are aftermarket screens. I haven’t purchased an iFixit screen in a while so I can’t say for certain but I would certainly expect an aftermarket screen to be of lower quality than an original or premium level screen. That said, iFixit does stand behind their products so contact Support and see what they say.
crwdns2890332:0Micro soldering Audio IC for iPhone 7crwdne2890332:0To do an Audio IC repair, you need both the soldering station and hot air station. The hot air station will allow you to remove, reball and solder the audio IC in place. The soldering station will allow you to make the micro-jumpers necessary to complete the repair. Of course, you can get the Quick Hot Air Station which is really good but much less expensive than the Hakko. However, for the soldering station, I highly recommend the Hakko. Of course, you also need flux, solder, tweezers, various consumables for cleaning etc. This is a considerable investment in cash but also time, don’t do your first micro-soldering repair on an otherwise good device…not to mention that the Audio IC is a deceptively difficult repair with plenty of gotcha’s that can turn your phone into a brick. If you do this, get some dead or iCloud locked phones and practice a lot first.
crwdns2890332:0Backlight bleed and some other questions after new screen installationcrwdne2890332:0This definitely looks like a poor quality screen (as to be expected. from Amazon/eBay suppliers). It is possible you damaged something or screwed something too tight so you’ll want to double check that while your are at it. As for the LCD adhesive, once you open it up, the adhesive will peel away irregularly. This brings up an important point when doing screen replacements. Always text the screen with the phone partially assembled before you lock it in. There’s nothing worse than sealing the device before noticing an issue or a forgotten screw or shield :-(.
crwdns2890332:0Device restarts when the progress bar appears when trying to restorecrwdne2890332:0There are two things to unpack here. First, if the phone got stuck in a boot loop suddenly, what happened before that. Was the phone dropped, repaired or came into contact with water recently? Secondly, are you attempting a full DFU Restore or Update? iTunes Error 4013 is usually NAND related. Seeing as how this happened after an attempted Restore/Update, there is a strong possibility that the memory was corrupted. Was the device pretty much at it’s memory capacity
crwdns2890332:0Why is iPad constantly rebooting post battery replacement? See videocrwdne2890332:0Roman has made an excellent suggestion but to me, the red flash is worrisome; this is usually associated with NAND issues. The NAND memory IC would have to be de-soldered, re-programmed and then reballed. Certainly not a DIY fix.
crwdns2890332:0iPhone XS laging and restarting after 3mncrwdne2890332:0Back Glass or Whole Housing replacements can suffer from the same issues, mainly damaged flexes or connectors. If the phone works fine without the cameras, then closely examine the camera flexes and connectors (and the equivalent connectors on the logic board. Look for tears in the flexes, even the tiniest ones. Sometimes the connector pins get damaged or some surrounding components can be fully or partially dislodged. All of this inspection may require some magnification. EDIT 2020-10-26 Take a closer at this flex, based on your picture below (https://ibb.co/g9qRMTj).
