Iphone 4s error 29 (cannot update the iphone) tested 100% work

If you have iphone 4s and then stuck on recovery mode, and when you try to update or restore it you cannot do it because the itunes is errror 20 occured. the other people say it must be jumper or replace the resistor in the side of the connector battery if missing. and the other say must be replace the battery with the original factory not KW or the new brand in the local area..

2 days ago I had the same problem.........I have to resolve the issue and fix the trouble  

My previous attempt to replace four resistors which are close to the battery connector, sthutdown the Antivirus, update the windows, renewing the itunes but it is not functioning at the time of updating, iTunes is still an error occurred 29. 

remove 2 resistor which is marked by a circle

and

 check the red line is connected 

and then replace the battery with the original factory, if your original battery is pregnant it easy just replace the baterery only the cell of batrery new 

replace the flexible conector on the old battery to the new cell of battery.

just like that and then connect to the itunes its will work to be update.....

thank for coming..........good luck..
