It depends how much is the soldering paste temperature if it’s 183c you can use very low temperature it depends on every hot air station in my case I’m using 264c to remove the chip with air 68 and to solder a new one with the soldering paste I’m using 252c air 68
Hi! I do have 2 iPhone 7 intel version and on both of them I did replace bbpm ic and perfectly reballing the baseband cpu but it still no service no imei also dfu restores didn’t help! Any suggestions?! Regards mick
Antoine Kiriaky both of them just lost the firmware first of them after waterdamage and bbpm Chip replaced it worked after some time stopped to see firmware the second one did replaced bbpm and reballing bb cpu nothing more I couldn’t do even fixed audio ic weak pads! My question; where should I check for the important voltages! Thanks friend
I see now if you checked all the voltages on the BBPMU and also In diode mode and if you checked all the pads and voltages on Baseband for the water damage it’s hard to say especially if it’s strong liquid damage but for the one try to check GSMPA_RF it’s the 2G ic I guess because it’s very rare for intel models to have a failure transceivers but also check and also have a look at the low and medium band ic’s and see if there is connection between LATCP_RF - UATCP_RF
Did you change the ic or not?
Yes
What are you using to clean beautifuly the pcb ? Thinner or alcohol 96%
Ethyl acetate
@@AntoineKiriaky10 where do you get that, is it quite flammable?
can we replace iphone 7 baseband ic ?
One question your phone is helo screen but power on direct meneu how possible ?
What heat and airflow did you use to put chip back on and for how long did you heat it please ?

What schematic diagram did u get diode reading of bbpmu zxw????
I didn’t I used a fully working doner board
Jb ic utara jb board activetion pr tha or kam kr k jb on kiya tb active hua tha kasy????????
Porque no mostraste que los restaurantes si era necesario hacerlo
Howe to active the phone ( is the nader phone no ? )

History of the device ?

Antoine Kiriaky thanks! i will and let you know if there is any successes!
Where are you located? - Me , Vienna Austria
Lviv,Ukraine
Please any need for jumper wire
Great video... thanks for sharing... Michael waiting for the outcome
But what was the problem?
May be Pടuedo Soldered BB PM...
Thanks i need intel boad modern firmware solution
History ?
Great video nice
We must replace the circuit where we must remove only and put again
Replace
