Lenovo K920 (vibe z2 pro) Baseband version: unknown - Lenovo Vibe Z2 Pro Questions & Answers

Hi, i have (or i had ) a lenovo k920 (chinese version) i have installed via qfil a modded row rom. After that it won't read sim cards anymore (it show only two red cross). by typing on the dialer *#06# i sow that both IMEI was lost (both value was 0) so i replaced the right ones with a little software found on the net. It still won't read sim cards and i noticed that in "version information" it show Baseband version: unknown.
I have done anything: reinstall modded rom, back to stock rom, try another rom...but nothing changed. Please someone can help me?
ty and sory for my English.

ROW software won't work on chinese version of the phone. The radio is different so it uses different software. Therefore you cannot get SIM signal. Flash CN rom, root and debloat manually. That's what I have found to work so far...

Hello, I bought the k920 (china mobile 4G) new from a chinese friend who bought it for me in china. It came pre-manipulated for the international market with K920_ROW_S226_150429_TWRP_ROW.zip , MODEM_CN1.zip and SuperSU_for_K920.zip still left on the internal storage. I got access to all the network types and only the telephone function doesnt work somehow if LTE is enabled. It seems like the network types are also not able to switch between eachother at loss and gain of signal strength. So I am wondering what methods the chinese guys used to achieve my set-up... Baseband version is DI.3.0. Build number 226 and Android Version 5.1.1. And I checked my bootloader and it seems like its locked, according to the adb output ( fastboot oem device-info)
Thanks in advance... EDIT: and sorry for necro bump.

Defy+ plus no network - change baseband doesn't fix

so.. I have this phone parked in my drawer for almost a month and finally decided to seek for online help.
Last rom installed is cm7 (but i've tryed several others cm7.2 cm9 cm10 cm10.1). I've tryed using both the baseband switcher included in the rom settings (where avaiable) and the standalone apk. I live in Italy so I chose Italy in the baseband selection (again.. I've tryed several others basebands just in case...). The sim card is a working VodafoneIT sim card and it is recognized by the phone.
the problem is that my phone does not lock to any network and I see the message "emergency calls only".
I also tryed to flash original sbf from here.
I don't know if it matters but logcat reports these errors:
Code:
E/GSM ( 6427): RIL implementation has returned an error where it must succeedcom.android.internal.telephony.CommandExcep tion: GENERIC_FAILURE
D/RILSWITCH( 2018): RILD unknown at cell -1
E/GSM ( 6427): Wrong network type: 0
I remember that at the time of when the problem showed up the first time, looking on the internet, in addition to the advice of changing the baseband, I found a thread where someone was talking about a possible hardware fail.. but I can't find it anymore.
any suggestion?
thanks
up????
i'm also having this problem
anyone found the fix?
Does the same error occur in stock? If so then I think it's a hardware issue. You could try a different sbf of your carrier and region(a newer one), but I do not think it would help much.

Try with different bands from your country or another country with the same frequencies.
Pull the batery out for a few seconds.
Use the latest version of the standard app (not defy parts).
Regards,
It works for me with a different company of my country
My chip is Personal_AR and with this don't work, but with Claro_Ar works fine...

Note 3 Can't see SIM card after flash to Lollipop !!!!

Good day
I need your help, I just flashed my Note 3 (SM-N9005) with Lollipop 5.0 from sammobile.com
I used odin to do the flash and it ended up successfully pass. Right now, the phone is running with lollipop but it can't detect any SIM card !!!!??
the build number I flashed is for my country and this is the number
N9005XXUGBOEA_N9005OJVGBOE4_N9005XXUGBOD3_HOME.taror
Any hints or help guys??:crying:
Please any help guys
I'm still stuck with this problem, I tried all kinds of ideas after deep searches but non of them work so far
I even rooted my device and tried three custom ROMs but still my note 3 can't detect the SIM card and the IMEI is nul and baseband version is Unknown
any ideas
The issue is you must have chosen the wrong rom for your region. What Country are you in and is your sim from that country?
YOu need to flash a rom based on your CSC and sim ... I've done this a few times before and it always messed up when flashing custom roms, etc. The only way I found to fix it was to flash back to stock rom for my phones original region (ex: if my phone is from Japan, need to flash Japanese official rom for my mobile provider).
That should restore your IMEI and sim card issues.
If you're not sure, you can post back with details of your phone (CSC - region).
thanks for the reply . I can't really tel the exact location or region of my phone. but whe nI look at the box it all written in Bulgarian language.
I will try to flash N9005XXUGNG1_BGL and see what will happen

Xiaomi Redmi 2 - How do i check if my phone is 2014811 or 2014813?

Hello
Is there any way to check if my phone is Xiaomi Redmi 2 2014811 (with WDCMA 900MHz) or it is 2014813 (no WDCMA 900MHz)?
The sticker on box of my phone says 2014811 and so is sticked under phone battery BUT when i connect my phone to MiPcSuite it tells me its 2014813 this is unconclusive.
Im looking for a definitive way to determine if my phone is 2014811 with WDCMA 900MHz or its 2014813 without WDCMA 900MHz. Is there method to check if for example from inside phone, device settings, about phone, checking hardware status and modem number? Or is there something in Engineering Menu *#*#6484#*#* that will tell me what type of modem do i have?
May app like CPUZ or maybe other can look into hardware to find this information?
is your device rooted? You can check it in your device's build.prop.

If you don't mind me asking, is your phone brand new or refurbished? Because whatever model number indicated on the box and at the back sticker of your phone it should match the phone's hardware. Unless the phone has a custom rom. What does windows os tell you (model#) when you connect it via usb? You're suppose to get two (2) drives when you connect it to your computer like for example: (drive letter) E: Xiaomi and (drive letter) F: 2014817.

Phone is supposed to be new but seller was flashing it with other firmware (because in original its with chineese firmware). Im adding some more information that i got from the phone (Translated as best as i could)

This is from under battery, on the blue sticker with Hanzi it says:

And below
2014811 TD-LTE<Hanzi symbols>
CMIIT ID: 2014CP5147
<Hanzi symbols>
When i connect it to computer the device name is 2014813 (just as MiPcSuite says).
Generally im asking this, because im having "No signal" issue (phone detects sim card but no signal, 0 bars). In my country WDCMA 900MHz is nessesary. And seller promised me that he will sell me 2014811 version (with WDCMA 900MHz). So now, MiPcSuite tells me that its 2014813 and i have this no signal issue. And im worried that someone sold me wrong 2014813 version (without WDCMA900Mhz).
And before i ship my phone back to seller, im trying to figure out what is wrong, is my phone really 2014813 and i have no signal because of lack of WDCMA900MHz. Or maybe its just that MiPcSuite sees its as 2014813 because someone flashed me wrong rom, and thats why there is no signal (wrong modem file) and my phone is 2014811 for real (like it says under battery and on box).

You can use CPUZ, Antutu or even Geekbench to get some details. 2014813 is a Chinese Rom that's why you can't get any signal from your place.
Flash your phone with this release of MIUI 6: http://forum.xda-developers.com/redmi-2/how-to/rom-stock-kitkat-miui-6-fastboot-rom-t3375693 and you should be good to go. It has the global modem firmware. After that you can put CM 13 on it

Ok your phone turned out to be a Chinese (2014811 China Unicom) version according to this MIUI Link and in order to get the WDCMA900MHz signal you need to flash (via update.zip or adb) the 2014811 ROM.
Thanks everyone, with your help and generally pointing me in right direction problem was solved.
I managed to flash my phone with proper 2014811 rom. There were two problems, first installing ADB drivers, had to do it manually instead of using MiFlash installer.
Second problem was "Image and device mismatch" error in MiFlash which was solved with this guide http://en.miui.com/thread-178314-1-1.html
After that, proepr 2014811 wt88047 rom flashed, signal is back, all good

Install Chinese rom to ROW mobile version

hi guys.! I am from Greece and my z2 pro start the blue screen problem. I read that this phone works better with Chinese rom and problems like mine were resolved. Now my phone has 3 days which works fine. It runs lollipop android (K920_S271_150907_ROW), it is rooted using DragonVibe a8 kernel (unlocked bootloader) and it has xposed firmware too. My question is: Is it possible to FLASH official Chinese rom to ROW version of device? If yes then will i have to do some changes to make it work to my network? I read something about changing the modem to port the Chinese rom and by dialing *#*#5920#*#* to make it work with global network. :silly:

You have to use proper radio (modem) CN or ROW for device to have network.

IMEI issues no signal

i think i broke my phones imei and now there are no signals. The phone is not showing the correct IMEI and not getting any calls. Please help me i have factory reset the phone as well
How did you break it? Have you tried reinstalling the firmware?
Hi I am not the thread owner but I have a trouble with IMEI , could someone help ?
Well I have a Motorola Edge s30 (global name ) Motorola g200 (Brazil name) and I work in Motorola I am with a test one (with a proto hardware) (normally they give all the experimental mobiles to employees because after the launch of the product they are scraped or given to employees) it have a 2 IMEs (of course it's a dual sim )
The problem is :it is loaded with a stock ROM (with is for a normal mass production mobile), the test engineers do not have a appropriate stock ROM for this version ) and the stock one I am using now is without signal . because my mobile is not 100% identical to the mass production one I have the IMEI 0 IMEI sv 0 problem .
Can I solved this in a simple way ? If it need to flash how I get a ROM that it will work in this phone ?
