my iphone6's screen was cracked and bent as well, so i bent the phone back to normal and replace the screen, but after i have done everything, i find that the phone can not receive signal, it just say no signal. i am sure the sim card is working ( i tried it on other phone). i think i might have damaged the phone when i tried to bent it back.
so how can i know which part need to be replaced? sim card reader? antenna ?

Antenna may be your problem. I believe the phone reception antenna is the one on the lower end of the logic board, it is black and small with a silver/gold L shaped plug on the end that snaps down onto a circular terminal.

Looks kind of like this.
Before you do some work on the phone.
Try to...
1: Turn it off
2: Take the Simcard out
3: Turn it on ( 5-10 mins )
4: Hold home button and power button until the device goes black and reboots to the springboard
5: Turn off
6: Reinsert Simcard
7: Check if you have reception.
Also, try to dial *3001#12345#* and check top left what number is shown.
-51 = Full signal
-105 = No signal at all.
Anything in between those numbers is normal. The closer to -51 the better.

Springboard? Isn't that like Winterboard from Cydia with a jailbroken iPhone?

Hi!
I hope you're doing good and having a nice w-e !
I recently changed the screen and the battery of my Iphone 6. Everything was working just fine for a week until yesterday. I can neither receiver / send SMS, nor access 3G/4G.
J'ai démonté et remonté l'écran et la batterie
* I disassembled and reassembled the screen, the battery and the coax connexion
* I restored the phone and the carrier parameters
* The IMEI is still running
* The SIM card works on other phones
* I downloaded the last IOS and Itunes version
What should I do ?
Could it be a motherboard issue or a welding issue ?
Would it be worth trying to replace the lightening dock ?
Thanks in advance for your help !
