Mini Iphone (M188) HELP!!!!!!!!!!!!!!!!!

[Semobi77]

Hallo! Does anyone managed to read fullflash from a new model "Mini Iphone m188" ????? The box says CECT F188 but under battery says m188. The only cable fitted with infinity pinfinder was l12c, it says on pc that is MTK 6225 but i get no response from phone. This is phone number 7 and so far i never had a problem finding pins or reading full flash from mtk models. Please someone..... i need some advice!!!!

Here are some pics....

hello!

1. how did you get know that this is mt6225 inside?
2. please count number of pins in system connector. Is it really 12 pin ?
3. does this phone is able to be powered On from pinfinder power?
(this is important rule to get pinout found)

[Semobi77]

1.When i tryed to connect it with usb to pc it said MTK6225 Found.
2.Yes it is 12 Pins.
3.I don't know the + and - of battery to know where to place the cables (cause the battery cover is blank) so i tryed to play with pins without luck. The most common pin (+-) didn't work.

Let me know how to find with multimeter the battery pins and i will get back to you tomorow with greater pictures and more info.
I also have no idea how to open it and i'm afraid i might break it.

Thanks for spending time with my problem.

hello!

please take battery and check with multimeter (voltage measuring mode) where is "+" & "-" battery terminals.
connect pinfinder "crocodilles" to correspondent phone terminals.
Check that phone powers On and then run pinout search.
Dont forget to set L12C cable type and mt 6205-6227 MCU type
and hold phone power button pressed all the search time!

There is no way i can power up the phone with pinfinder. I know i do it correct
cause all the other phones started up immediately.
There is a mystery here but with your help i hope we will break this little sucker!!!

Waitting for suggestions......Thank you.

hello!

what is your pinfinder output power voltage?
have you removed diode from main infinity box?
this is must done procedure to make pinfinder work with all phones.

here is little example, how this helped to increase output voltage:

The trick with soldering the unibox WORKED!!! I finally got it powered up with pinfinder, BUT................
Maybe this little sucker needs new cable. I still can't recognise rx tx. I tryed all trhee options with mtk i did again with the leather keyboard pluged in also i did it again changing tryes from 7 to 20 and yet NOTHING.

I know we're close, any suggestions???????????????

hello!

did you hold power button pressed all the time while pinout search?

[Semobi77]

I have fixed many phones this is not my first time..... Offcourse i did!

[Semobi77]

Any suggestions????????????

hello!

OK, in this case we are sure, that pinout is not in system connector.
any handsfree port? maybe worth to examinta them too. L3A or L4A connctor.
if no luck: we must look for test points
disassemble phone and search for test points on PCB.
post PCB picture here, maybe someone will recognise it

[Semobi77]

Handsfree port is the same were i put l12c cable. I cant use these cables.
There is another port were the extra keyboard attaches.
I marked it with red color in the pictures and also the pins which i tested with multimeter.
Test points are under sim1 like i marked with red color in previous pictures.
The problem might be with ground cause its the last pin and its covered with black color.

Please tell me what testing should i do.....
Also i saw in the manual page 21 it says something about changing pinfinders config. What's that?

Thank you for trying to support this phone.

hello!

attach phone battery and measure voltages on Test points.
what voltages do you get?

[Semobi77]

I checked the pins from both ports ("side" l2c - "down" keyboard both) with battery and both of them showed 4.10v. With pinfinder i get 4.90v.
I used the pins from the pictures i posted above and the ones that matched with voltage. If you want another combination tell me.

[Semobi77]

According to the pictures i posted can you also tell me how to fing the Pin which is GROUND????

Thanks!
