Iphone 6+ baseband reball no power - GSM-Forum

deegee2016 · 01-08-2018, 17:09

Hi all wonder I someone can help shed light on this issue.

I have an iPhone 6+ with baseband failure , no imei on *#06# but and imei firmware in the about settings.

Found short on u_pmic and replaced. Short gone .

Then removed baseband cleaned pads all fine apart from missing NC pads which is fine.

I then recalled and replaced the baseband and had another short so removed and short gone.

I have 0.00amp at 5v and no power .

I have complete 5v to switch MOSFET near Tigris .

Any secondary issues with baseband install that can cause no power?

Thanks in advance dee

Hi there,cthanks for your reply, Yes the device does boot to apple logo and just hangs on it...that is with baseband removed. Forgot that no current pull if battery is fully charged already...

NY ideas?

I did think USB was an issue also as it only charged one way .

Hopefully once baseband is balled again I will have a clean install and no bootloop.

Will replace TriStar also to be safe...

Thanks again...
