Device : Acer Liquid Z320 (model no. T012) Android 5.1.1
So my friends device got bootloop after he install something that he can't explained (maybe something like luckypatcher / incompability xposed installer etc). Now after flash to it's stock from this site (vache-andr*id[dot]com) with firmware file Acer_AV0L0_T012_1.005.00_PA_GEN1 the device boot up and run nicely, but the problem at it's network. He can only connect to 2G (or EDGE if you will), and when i change it to 3G only the signal lost / no service / empty bar with " ! " symbol in the middle of network bar. I have check all the error like null imei etc but no error i have found so far. Here is what status has show on my device @3G Only :
Service state :
XL Axiata: out of service
IMEI1: (same as at the devices box)
IMEI2: (same as at the devices box)
for dev who want to get my logcat i have provide the file in the attachment. Please i'm really really depressed for working this device almost 14 hour's and have no clue for fixing it. I have try flashing NON-HLOS.bin file from it's firmware file via fastboot (after i unlock the bootloader with " fastboot oem unlock " command) but still same error. i double check the imei and it's still same as it writen on device's box (both first and second imei). I google up but all the repair tool is only for Mediatek which the device i have working on it is Qualcomm so i don't want to broke the device too far and keep searching another way.

I have recently bought a fake Note 4, but it did not work on T-Mobile, so I tried to flash a radio image to it.
The problem is the radio does NOT work,the symptoms are:
1.) Mobile network type = UNKNOWN:0
2.) Service state = Radio off
3.) Mobile network state = Disconnected
4.) IMEI = Unknown
5.) IMEI SV = Unknown
6.) Serial number = 0123456789ABCDEF
I think the device has a MediaTek MT6582(faked to look like a MT6592) processor, and it has android 4.2.2(it is faked to look like 4.4 though).
It has NO recovery, when I boot into the recovery I just get some china BS, Testing, Factory reset, and version info(which doesn't work).
I have already tried putting in a new modem.img that did not do anything
A search of the build.prop says it is a sangfei82_we_jb5 device, I can't find any information on such device.
It also says it is a ALPS.JB5.MP with a MP version 1.000
I do not have any backups or files for it(which was very dumb I know).
MTK Engineering mode does not change IMEI or send AT commands.
Is there any way I can get it to working order so I can make phone calls?
BTW the WiFi and Bluetooth are both still working.
Hello XDA, I have been a user/fan of xda for about 5 yrs now. But I havent found a single problem that I didnt find the
answer for here on xda, or somewhere else (Google). I have a Computer and Phone repair shop in Ethiopia and I used the
internet and mostly XDA to Unlock Sprint HTCs, Unbrick Galaxy S/ SII/ SIIIs, repair corrupted efs partitions, install
custom roms like CM (on almost every smartphone I come around), fix bootloops of Best devices like Xperia Z, Galaxy SIII,
Sim unlock Moto Droid ...
But I have faced a serious problem and have been trying to solve it for about three months now.
To the real problem
There Are these MTK MT6582 Devices, Mostly Huawei devices (G730, G610, G630) and they are recently getting a major IMEI
failure (IMEI : null). I have tried through the ff methods (that I use for other MTK devices like MT6572, MT6575) With no
luck
1. Maui Meta 3G - It reads the devices in meta mode
- It can read the version (in "Get Version" window)
- I have selected the Nvram database of same baseband
- It fails to write the imei when I click "download to flash" It either replays "Check the load and device versions are the same (ish)" or "Download to flash time out"
2. IMEI & SN Write tool - Doesn't seem to read the device in meta mode.
3. MTK Droid - Rooted the device
- Restored "nvram" from another working phone
- Rewritten the IMEI
- Still the same (IMEI: Null)
4. Reformatted the whole device and installed firmware with "secro" file - Still the same - tried the above methods again, still the same.
Dear XDA Fellows, I am exhausted with these devices and they are keeping coming. So, Please help me solve these problem. Thank You.
P.S - I dont know where to post this, if there is another appropriate thread, lead me.
I recently tried installing this rom https://forum.xda-developers.com/vivo-5/development/rom-aosp-6-blu-vivo-5-clones-t3489281 but it did not work very well.
It is now appearing as invalid IMEI.
Any idea what I can try?
I've tried the MTK Droid tool, MAUI, SN Writer but none of them recognize the smartphone.
Try with this:
PD: Have you problems with WiFi?
For a temporal solution you can use MTK Engineering Mode (The Monster) from the Play Store. I think maybe you need to be rooted.
MTK settings
Connectivity
CDS information
Radio Information
you will see AT+, delete the plus , add the plus sign choose the first option (in my case AT+EGMR=1,7,"")
Put the your EMEI in between the comas "EMEI" if theres an error put a space between the + and EGMR
for the second EMEI select the second option AT+EGMR=1,10""
This will work until the phone is reset

Hi
I want to know that if my phone is dual sim phone then why only one IMEI number is shown in fastboot getvar all
Also I am not able to use any sim, I have again flashed stock marshmallow and the IMEI are showing 0 for both sims
In the past i have flashed roms for single sim and have flashed some different custom roms as well
So what I think of it now is that, maybe my variables list is for single sim phone (imei), for dual sim it must be like imei_1 and imei_2 and the rom is searching for these variable and they are not found and hence showng 0 ?
So what is the solution to this problem ?
PS : I have no backup of .nv_data or efs if you are about to ask such question. I have both IMEI numbers on the box as well as on the phone.
Any help is appreciated !
Thanks
Good that you have the IMEI numbers. For starters, download the latest Stock ROM for your phone and boot to Bootloader/fastboot mode.
Code:
mfastboot erase modemst1
mfastboot erase modemst2
Then try to install the full Stock ROM using instructions available in the forums, then test out and see if it works. If it still does not work, then install QPST (instructions available in the forum to install and connect your device)
USE CAUTION when writing NVRAM, you can write any junk and there will be no warning sign. From hereon, make notes of whatever you do !!
Once the device is connected, dump a local backup of NVRAM to your PC. Then locate the ID number for IMEI (could be 550, good to confirm though cause am not sure about dual IMEIs) then you need to update the IMEI number in a specific format (ensure you're entering them as HEX), if you read through the forums, you should find the correct sequence, starting from the 2nd digit, you basically reverse the digits.
Once this is done, and you restart out of BL mode, most likely your phone should be back up and running. Proceed to run a full Stock flash and hopefully you're up.
I'm giving you top level instructions on what to do, because you need to do a lot of research before messing with NVRAM values and during your course of locating all the info I've asked you to look for you should find them.
Cheers !

Hi , first your device is x552 model not x522 but never mind .
In order to fix imei you need to flash nvram.bin and you need to allow in scatter file nvram.bin to be flashed.
First download this firmware:
https://www.4shared.com/get/H9yvkOUoce/MT6795__Infinix__Infinix-X552_.html
Once you download , extract on Desktop , make new folder on Desktop and put just MT6795_Android_scatter.txt and nvram.bin which you can find in Extra files folder.
Now in order to flash nvram.bin you need to edit scatter file and enable instaling that file .
Here you have easy video instruction to follow:

If you solve the problem , edit this post as SOLVED!
Good Luck
Any One suffering from same problem, Below are Easy steps to fix Unknown Baseband version, NULL or Invalid IMEI and SIM cards / Network signal not detected on a Mediatek Android phone.
Before you proceed, ensure that your Mediatek phone has a valid Baseband (not NULL Baseband). If your Baseband is unknown then download the firmware for your model and flash using SP Flash Tool . Flashing the firmware to restore Baseband. With Baseband regained, you can then proceed with fixing IMEI.
You can use below mentioned tool to ENter EMEI again, But your mobile should show a valid baseband version or the below tools will not work.
SN Write Tool (SN Writer) method
Maui META method.
