any one knows how to solve this issue i checked the voltage going to nand all powers good 1.2, 3v, 1.8 all good

по питалову смотри.или и2с

4005 - no cpu-nand connection, usually . If all on board okey, try reball it, but you need test points under nand.

Он наш слэнг прям вот сразу так понял !))

[console-maste]

try to measure resistance (to gnd) or voltage i2c0 i2c1 line
probe points PP0301 302 304 305.
Some bad components can distort i2c signal
this is first of all

second, you need to desolder u0604
And try to test CPU connection
you can measure solder points resistance to gnd.
If R= infinity in some data line, you have open circuit and reball CPU is needed

[d42k11]

I tested the resistant on the battery connector the R between gnd copper on the board and + of the battery connector is 0.958m. The R between 2 connector terminal of the battery is 220k and counting means going up i had black probe of the meter on gnd terminal of battery connector and red probe of meter on + terminal of the battery connector and if i interchange the meter prob i get different R readings 13.56k

will the pp0601,0602,0603 help me any to test the cpu and nand connection ok or not? the pp0601 is on page 8

[console-maste]

by the way, problem is very hard, if its nand-cpu problem. if you are not hardcore specialist - forget it

I2c problem -more simple. Try this
test i2c first. find that pp on the boardview! and measure

Battery coonector is nothing matter, forget it

for example, similar problem iph5 4005 error
In some cases simply solved by desoldering compass chip.
BUT in some cases this is cpu problem
And in some cases -nand problem

All the PP are I2C point? on the boardview? Also the numbers next to each trace they refer to page number where the trace occurs right>? IF yes they are off by 1 page number like for example if it says 7 it occurs on page 8 am I right about please correct me also much much thanks for help me

Thank you for all the help . I dont know what happened but After i removed emi sheild from cpu and tested to make sure phone boots up. and i connected to computer the phone went through restore process and everything went back to normal I dont know what changed thing that made phone work again and restore. any explanation will help me solve this problem faster in future.

thanks again guys

Noone can say exactly about the reasons. Maybe it was poor solder joints under CPU/RAM/NAND/etc due to factory defect or shock. What you did is a kind of so-called "reflowing" but because of the compound under the chips and without following thermal profile is a lottery. So you were lucky this time. You should better test the phone because it can fail again soon.
