Chosen Solution
I replaced the digitizer, it went flawless. But I had accidentally cut the home button flex when closing up. No big deal I just took it off and used the old flex. All was fine. After sealing it, reconnecting the battery, I forgot to unplug it from the computer from when I finished last time. So I just unplugged it and it seemed fine. After I closed the screen, I pressed the power button and noticed the Apple logo and all, looked normal. Then, it flashes BRIGHT red, then crashes. Then it starts, RED FLASH, crash. It’ll do that all day if it could. Now I did a lot of research and tried to restore it, I get the infamous 4013 error. So before I just trash it, is it the charging port or is it the NAND chip? I watched iPad Rehab say that NAND chips can cause the error, but others say it can be a port problem. Do you think the port somehow fried because I left the iPad connected to a computer during battery removal and reconnection? Or did the NAND chip get fried? I offered my client to take my iPad Air as a replacement, they refused. I should’ve been smarter, I feel really hadn’t for them, and kinda what to know if it’s just the port so maybe I can solder a new one on. Things I’ve tried, Dr. fone 3uTools DFU Restore Recovery Restore I’ve removed all the external connections, like power, home, digitizer, antennas and LCD and tried to restore. But the Hardware error still occurs. Nothings been able to revive it.
An error 4013 for this device is probably a NAND issue. Leaving the charger connected while reassembling may have corrupted some data. You might also have a charge circuit issue. I doubt the charging port would be the issue, it is a mainly passive element. In the end, nothing can really be tested here without some micro-soldering experience. I see no reason to trash an iPad Air until you can at least determine what needs to be repaired.
Have the same issue with a iPad Air. Constantly boot-loop with red flash. Did you found a solution or trashed it? I have not been able to determine the error. Maybe the NAND as mentioned? That would be beyond my skills and equipment.
I just figured I’d do my civic duty and let anyone else know what was causing my iPad to do this. I was replacing the homebutton on a lightly water damaged ipad Air 2, and when I went to turn it on it would flash red and keep looping trying to turn on. I removed the new homebutton that I installed and the ipad turned on and worked fine. So if you are putting on replacement parts they may have something to do with it!
