how to fix apple error code 29
iPhoneの5代目となるiPhone 4S。このデバイスの修理は比較的簡単で、スクリュードライバー、開口ツールと忍耐が必要です。GSM/CDMA / 16, 32, 64 GB / 白と黒
Same for my iPhone 4S. WiFi upgrade to iOS9.3 from 9.2.1 failed/stalled. I then tried connecting to iTunes as the phone was stuck in recovery mode. It still failed about 2/3 of way through and left me with a phone that was not functional.
After 2 hours (over two days) with Apple Tech on Chat they booked my an appointment at the local Apple store. I was not happy as the phone worked perfectly until this upgrade!
Given error 29 is related to the battery or battery connection (by all accounts). The new battery (non Apple) which I installed 3 weeks ago and replaced with an original Apple battery. I also scrubbed the battery connector terminal on the motherboard with a soft toothbrush and rubbing alcohol.
I reconnected the phone to iTunes (old battery) and the upgrade was able to complete. I then replaced the old battery with the new non genuine one I had removed earlier and the phone is working fine.
I don't believe my new battery was faulty nor was there a hardware issue as such, but possibly the iOS9.3 is sensitive to non genuine parts in an old phone!
Good luck if you come across a similar problem as this may help you.
just fixed my 4S (at least for now) after replacing battery. After plugging in to charger, I got the dreaded plug into iTunes symbol. After trying to restore numerous times to no avail, I plugged back in the old battery. I was than able to do a factory restore. replaced the old battery with the Ifixit battery again and it is working so far.
Hope I don't have to do this again and again....
I had this problem on a non jailbroken iphone 4s tried the above to no avail .
Basically if you've exhausted all the other fixes... changing the battery,removing firewall,antivirus,editing host file etc etc. Then check the last line of your itunes restore log if it says something like...'RamrodErrorr domain/3ea: update_gas_gauge: gasgauge_swupdate returned -1' ... Ifixit has the answer and more details here.....
In my case on a (very)close inspection it's a capacitor.. that's missing!?!.
Hope this helps someone as this info took me best part of a week to find!
Easy fix :
1.Error 29 is a hardware problem, Mostly replacing battery or repair in the slot of where u insert battery inside iPhone :)
