[Q] No service after formatting the yl-parames and NVram partitions on coolpad 7295

I've bought this Coolpad 7295 phone for less than three days from China.
It seems that I couldn't flash my phone back to the state where I could get the service for calling the first day.
After the second rom flashing with my flash tool. I kind of formated the Yl-parames and NVRAM section of the phone.
I don't know these two mean! Could someone explain how they work? Are they related to the hardware or the motherboard of the phone?
After the wrong formatting action, my phone could not make any calls. (But everything works, and network works also. And later I flashed many roms, all of them work, just no signal)
So the third picture shows that this device has a different partition compared to the most smartphones in the hardware called "YL-parames".
My friend who is good at making custom roms in Taiwan said I might accidentally screw up with the hardware partition.
I just want to know with this problem appearing, is there any other way that I could get my signal back?
I've tried several methods like rewriting IMEIs, reinstalling the official roms, but none of them work.
Or should I just send it back to the dealer to get it fixed? (I'm doing it right now...)
Just want to know in case the phone is back, how should I operate this flashing tool because I'm really a tech-savy
1) The first picture represents what i chose for the outcome of no signals later on.
2) The next one is its interface
3) The next one is the official flashing tool, but I still can not flash the CPB provided by the official since my hardware seems to be broken.

I would really like somebody to develop the custom rom in the English version for this device, this device is pretty good!
Or is there anybody using this phone as well? It's nice to have someone to exchange info with!!

Câmera problems!

My Moto G 2015 xt1543 have a problem with the two cameras, out of nowhere they stop working with the error message about restarting the camera and only return to work when you want. This disappointed me a lot on the device, I have done reset, cache cleaning, software update and nothing. Has no solution it?

first, wrong section.
second, you gave us NO details about what rom you're using, etc
third, your image didn't post so we can't see anything you're talking about.
I can't help you with what you've given me to go on.

I can't see any possible way flashing the correct factory rom does not fix this. At this point there are two possible scenarios: 1. hardware failure 2. user error...the correct factory rom will fix anything and everything unless you have hardware issues.

I have the same problem, I flash android 5.1.1 android 6.0 and the problems continues, I flash a Cyanogenmod rom and the problems continues I guess that I broke my camera but I'm not sure about that it doesn't have any visual crash or something like that, I have Dónde every thing and nothing works.

Did you try a different camera app?
(It's very unlikely that it will fix the problem, but doesn't hurt to try.)

i searched all over the net and i didn't find how they do that @_______@

Flash it to moar 7 rom. Everything you want is baked in the rom

what do you mean bro ?

can you please explain more

any ideas ?

Moar 7 is a custom rom. Its. Very fast,stable and it does to Hotspot and a bunch of other stuff right out of the box.
Oops reread op you have a g900f.moar is a sprint rom g900p,i saw a flashable zip for hotspot in the forums. Maybe you can try that.

i am afraid to loose the sim unlock or the entire phone if i flash it
because i didn't find cases like mine in the forum

I tried with the following firmwares but the result is the same I can not have the sim signal any operator

Did you tried all this firmwares?
Try the last one with full wipe.

I also full wip by flashtools
also here with probe through OTA 6.0 and 6.0 does not detect the sim
You could give me some other ideas?

Usually simlock.ta is ignored by Flashtool, can you verify that it was really flashed? (check your logs)
Also, can you get your imei by dialing *#06#.
Did you buy the phone first hand?

If you buy the new phone you drive sony but neither could give me solution
imei is clean does not report
the sinlock gives me the problem when you restart the phone does not recognize any operator and probe with different sim
and not know what else do help me please

I just installed M in the terminal marked the simlock option left but the result is the same I leave the log flashtools
thanks for helping

I'm same as you, have you gotten any solution?
