Yes , it can't get network , I have flashed kdz&tot , didn't work

If you flashed your phone and still no network it is probably a hardware issue.

It can search signal after I flashed a QCN file , but it is not stable , it losts signal sometimes , and need to reboot , so I think it is the problem of hardware , I am finding another file , I will try again .
Or can you backup QCN for , and remove sim card when you backup .

Can you send me the link of the QCN file to download cause i have the same problem..

No one should provide their QCN file because it contains the IMEI of that phone.
You don't have any network, right? What is your ROM, modem version, G3 model? There is a menu to manually select the network in the settings. When you go there, does anything appears?

It can get network after I restore a QCN file from other's , and I changed IMEI to mine , but it sometimes losts network and I nwed to reboot to fix it , then I don't know How to fix it totally or what problem is now .
My device is D855 32Gb ,the problem was up when I am using fumics 6.9 , I am using it normally and suddenly lost network and notice “remove SIM card…”, I flashed kdz and tot , but don't work , so I tried to restore QCN file .
Do have any ideas for this ?

Lost IMEI need help

Dear Friend,
anyone of you have G-PRO especially those with non-international version should backup your IMEI before trying to upload any new ROM. To back up, please download the tool below (I took it from M_Tool of someone I don't remember) and run it from a CMD Administrator windowl; you should also have your phone connected with debug mode, rooted phone and adb.exe shall be in PATH.
I bricked up my phone with losing the IMEI, i could restore partly now but could not connect to 3G network (only GSM). The reason was that my back up lacking of some files. So anyone have G-PRO F240L or a 988 please be so kind to give me a version of your backup. I need that to make my phone back to a smartphone.

Quang

Have you tried taking your phone to a service shop? I believe that would be your best shot. They might restore it in a matter of minutes...
You might have better luck choosing an independent store rather than a licensed one.

some times its a imei issue. in my case it was sim tray issue. i had to change the sim tray from service center only.
have you taken backup before flashing new rom?
if yes, then restore the EFS folder from CWM or TWRP backup

Try to flash with Odin exactly the same firmware you initially had.
Your IMEI should return then.
IMEI backup is about the very first thing to do before flashing any custom ROM

thanks guys for your output i just found this article http://forum.xda-developers.com/showthread.php?t=2088809
by flashing via kies. it will automatically detect your original firmware and what region by putting your serial no only.
i never try to flash other country. i only rooted my phone then using custom ROMs without a problem for network before then decided to go back to unrooted original Samsung firmware.
i think the original firmware is (deutsch) because in the start up setup deutsch language appear. then i set it to English (united states).
my problem now is the WiFi went back off & on. do you have any idea how to fix this permanently without using the code of *#1100#.
because last night i flash the Philippines firmware WiFi working perfectly smooth but no network problem! i think theirs a conflict with the region. if i can only decrypt the file then get the wifi settings. pls help...

[Q] No 3G

Hello! I have one issue with my xolo q1010i.
I mistakenly formatted my IMEI by SP Tool or by while changing ROM. With the help of MAUI META 3G software, I am able to get back the signal. But when I changed the Network Mode from settings to "WCDMA only", it cannot detect signal anymore which was used to be applied before. And even unable to enter in engineer mode from *#*#3646633#*#* from both JB and KK. Even mobile uncle tools did not detect the engineer mode. But through Xposed framework - gravity box, i am able to enter engineer mode, but nothing to do with it. I think my device lost the 3G band..anyone got experience about it?? I will be very grateful
Your sim might not be support cdma unless it's postpaid I guess

I did not say CDMA, its "WCDMA" which is 3G only. This is because while flashing with SP Flashtool, I wipe all the IMEI but thankfully get back those IMEI with MAUIMeta 3G by Mtk. But still some error is there, may be a baseband error because when I switch the network to "WCDMA Only" it cannot get any signal at all which is used to be working before. This means that there is some issue with 3G, I found one link, how to fix 3G issue here --> www[/url][dot]chinaphonearena[dot]com/forum/Thread-Tutorial-3G-fix but this is for a specific device (Zopo ZP810) that it provides .ini file which will fix the error - it is named as ZP810.ini. But I did not find this ini file for my xolo q1010i or for mt6582..can you try helping me ASAP
same here!!

Hi.
I bricked my LeEco X800 Le 1 pro and when I recovered it doesn't recognizes sim and the IMEI number is 012345678901234.
The radio in Phone info is off and I cant turn it on.
Preferred network type can not be changed.
I tried to use QPST to change IMEI, but it does not connects fully.
Tried rom vresions:
Le1PRO_US_X800-ROW-PB-v60-CUOCO92-5.5.014S.zip
Le1PRO_US_X800-ROW-v48RL-CUOCO92-5.5.011S.zip
I used QFIL to unbrick my phone and then it had 8gb rom so i formatted phone.
Now everything is ok except IMEI and sim problem
Help!

I have the same problem. No imei. Phone does not detect Sim card.
There is already topic about this here http://forum.xda-developers.com/leeco-le1-pro/how-to/imei-lost-imei-letv-1-pro-x800-brik-t3430035
We need a QCN backup from working phone to solve this.
Please Try my QCN file from my working phone.
I used Qfil for backup.
The user "mariocolino" from Forum.le.com has confirmed that this QCN backup has fixed the signal problem.
I hope it will help other X800_us owner with the same problem to repair their phones.
Some helpful tools & files.

This worked for me to enter diagnostic mode.
I flash QCN, imei appeared but there is still no signal and no sound, what can i try.
Use this brush tool. => https://1drv.ms/u/s!AidiAJYxvGs2cPhtLogbcsqjYEo
It will get back all system defaults.
BUT WARNING!
It has a malware that installs apps itself.
After brush tool install custom ROM like cuoco92

if 4G doesnt work, try flashing the Non-HLOS from an x800 US image
Yoy can also see if you can activate the bands on the QCN file with QSPT

(You can open the QCN with 7z)
compare the one that is working with other that have 2IMEI and see the differance and try to edit with a hex editor, if you can't then your best bet is 4pda

What board version do u have ? I lost my imei too when unbricking with Test point via edl
I couldn't restore my imei can u tell me your Telegram so I can ask you some questions tjnx
Try searching for these terms on google. "deadboot repair" "edl" "firehose". Usually after flashing a deadboot repair package the imei resets by reading the chipset. Goodluck.

To my knowledge the imei value is stored/burned in the soc on all snapdragon chips. I am not sure why it did not auto regenerate after an edl flash.
