Hey maudbrechet, try to redo the installation. Sometimes things can go wrong. Also if it reboots when you charge, you might need to replace the battery.

-Let me know how it goes.

Hey Apple !

Thanks for you advices !

I tried two times to restore it, but the restoration stops when it's about 2/3 complete, according to the logo under the apple on the phone screen.

At the same time, iTunes explains that "an error occured (29)" ...

I let it twelve hours ago but it didn't progress at all.

I changed the battery one year or 18 months ago, and I wanted to search the original one to try if it works better (hope I keeped it somewhere), but my father think that it's not a good idea to place an old battery that began to have a reduced autonomy in an iPhone that is already "not completely healthy". What do you think about it ?

Thank you for your help !

(I'm sorry if I make english mistakes, I'm french !)


Definitely try the old battery. Your father was just being careful that you don't break your phone. Trying the old battery(if it's not faulty) is helpful in figuring out whether the new battery was faulty or not.


I just tried the old battery, it seems to WORK :D

It is restoring from iCloud.

Thank you very much for your help !!


Awesome! I'm glad it worked.
