Lost baseband and IMEI after flashing Stock Rom with QFIL - Lenovo Zuk Z2 Pro Questions & Answers

After I flashed the 1.9 Stock Rom I lost my device IMEI and baseband, so no SIM signal at all.
Then I managed to put my IMEI manually using other QCN provided in a Z2Pro thread. But I still don't have a baseband, my device recognised the SIM card but don't have signal yet.
I saw some tutorials about how to flash a baseband but when I enter in fastboot mode my PC won't recognise my device, it just keeps with a yellow exclamation mark in device manager.
I'm on Win10 64bit right now. Please, help!

my phone have no iemi number and the firmware info are :
PDA : I9000JPJPG
Phone : Unknown
CSC : I9000OJPJPF
Odin wont recognize the download mode so i cant flash stock rom

i have clockworkmod recovery, tried flashing different roms and radios still nothing. it also gives me baseband unkown. what should i do???
the problem is the phone wont recognize the simcard , everything else is normal.
Is that due to you installing a rom that does not have your network
in which case in the settings manually add your Networks details apn etc .

Try see if your clockwordmod has any backups? Usually when doing changes it does make a full system backup..
If so, try restore from there, it should also restore imei
Not forgetting your backed up efs folder can be replaced if you did back it up most ignore that faq .
Mine came back with install of a new rom .

I had the same thing, I had to use the 3 button method and used Odin but remember that you have to have Odin running before you connect your phone to your USB connection and you should also have your phone in Download mode using the 3 button method before connecting it to your USB connection. Otherwise Odin won't recognise it, Also you need to make sure you have the phone drivers on you PC.
I just downloaded a stock firmware from samfirmware.com and that installed brought it back to how it was when I bought it. (Fully functional) and then I tried again with rooting it and lagfixing it. works fine.
The reason why mine died in the first place was because I didn't wait long enough on the first boot after the flash and I had thought it had frozen when it was really still just writing new information to the hardware so remember to be patient on the first boot after the flash.
It seems your phone Modem part is not flashed properly thus you could not retreive the IMEI from this part.
Suggestion:
Try to locate the original ROM which comes with this phone and flash it again and check if this works. From this start from zero
Couldn't you flash the modem via clockworktecovery if odin doesn't work? Much more simple if the missing modem is the problem. Modems can be found via docs thread.

If you are not even getting Odin to connect to your phone, your bootloader must be corrupted. If the phone can get into APX mode, you can flash new bootloader and start off from there.
Connect device to Windows PC and see if Windows would detect the device to start with

[Q] Semi-bricked, USB not recognized, doesn't even charge

Hi!
After searching the forums for a while I did not find a thread exactly matching my problem, so if I've overseen it, please just point me there.
To my problem:
I did a very stupid mistake, flashing a new custom ROM with a different kernel (as usual, cooked in Docs Kitchen) without converting back the lagfix. So I ended up with a non-booting phone - so far, so bad. Note to myself: Never flash a phone during the carnival weekend again.
So I booted into download mode and tried to recover it via Odin, but here I got my really bad surprise: USB device is not recognized, thus I Odin does not see the phone.
I tried 4 different PCs with Win7 or XP, a Linux desktop and a Macbook. I also tried 5 different USB cables (they all work with other smartphones like the Desire and the HD2). Wherever I stick the phone in, it is not recognized (code 10/code 43 in Win7). I used the stand-alone-drivers from the sticky forum thread here, and also most recent Kies versions, always the same: USB device not recognized.
Does anybody have an idea how to revive the USB connectivity? I'm almost at the point to send it in for repairs...
Or can someone elaborate how I could have killed USB with corrupting the ROM? I've to admit I do not really understand how these two are connected.

Hi Amokbunny
You get into download mode but the PC won't recognize the phone?
That's messy and I can think of nothing that could have done that. you did not change the bootloader did you (flashed a full samsung ROM containing a bootloader, for example VJ1)?
If not I guess it's a hardware issue.
formatted to ext4 without any backup
I did a very stupid mistake too. Got darky's rom 9.3., installed i, everything worked great(really awesome thing), then i wnt to recovry mode and entered tthe speedmod and it showed mr that my phone has rtf files system not EXT4 as it should be, thou i installed the speed mode. then i chose to repartition it to ext4 but i didn't choose the backup. Just clicked to format the sd. It did formatted to EXT4, rebooted, i saw the darky's rom logo and the the phone vibrated and the logog of the droid just flashed. I tried to enter recovery mode-didn't load. Started the download mode connexted to pc used ODIN 1.7 with PDA I9000XXJPY.tar, MODEM I9000XXJPY.tar, GT-I9000-CSC-MULTI-OXAJPY-LITE.tar s1_odin_20100512.pit.
The phone has started, appeared teh stok galaxy s logo and it's just flashing. Help needed. Don,t know what to do know. I have galayx s i9000 european version.
somehow i've managed to install new firmare 2.2.1 /I9000XXJPY-baseband /2.6.32.9 [email protected] #1-kernel version, but z4root isn't working. When i start permanent root the programm ends on aquiring root shell, the debug mode is on
Got it all running, installed Darky's rom 9.3. Thanks anyway.

Yep, I can boot into download and recovery modes, but that's it.
The only apparent change in the new custom ROM was the kernel.
I also cannot really access my external SD card (it shows me some phantom files, but not the actual content of the SD), otherwise I'd try to recover it this way.
I agree with the hardware issue, if it wouldn't have coincided with the flash procedure...anyway, I think I'll send it in for repairs if I don't get it to run on this sunday.
I have the exact same problem, except that I can access my external SD. I got the problem after upgrading to Darkys Rom 9.3 the usual way, but switched from Speedmod to Voodoo. After that update, my USB didn't work anymore.
I can't get neither Xp or Win 7 to recognize my phone. USB device not recognized, and tried all the tricks. Reinstalling Kies and drivers, switching between the different modes (storage, kies media, ask, debug...) But still no USB connection.
I updated to darkys 9.5 (transferring the rom using bluetooth, and updating using CWM), but still it doesn't work.
Can get it into download mode, but still can't connect using USB and Odin.
HELP!
Did anybody ever find a solution for this?
European version of I9000, bought in Denmark. No Simlock
Same thing here after installing JV1 + Ultibread Rom 1.4... Still no solution
*shameless push*
Any solution here? I dont have that problem, but it sounds too scary to not have a working solution :S
Same prob here! Any news?
Any solution? I have the same problem.

But if you are in download mode on your fone you'd rather should have a look at your configuration on the computer. Because the fone still can be flashed if the symbol for download still appears.
- Kies is shut down while ODIN is active?
- latest Samsung USB driver installed?
- Odin started with Admin?
Btw. did you try to get into recovery mode? Maybe this also still is working as the partition is quite small and chance high that it was flashed w/o faults. So you may be able to flash a zipped ROM rather than a tarball for Odin.
USB Not working when Phone plugged in... try these..
Unplug Device from PC..
Windows go to Device Manager...
Scroll down to Universal serial bus Controllers
Start with the top one and work your way down ..uninstall them all..
When done reboot Computer and let it install them all.. then try again
2.Settings --> USB Setings (under wireless & network may differ depending on Rom used) --> Try other settings Mass storage
3.Different USB ports on PC
4.Uninstall KIES from PC (reboot PC to take effect) and Reboot and just install samsung USB drivers....
5.Using windows type in msconfig in Start>Run box... windows will pop up and untick KIES from STARTUP TAB
Apply to take effect and restart machine.. try using ODIN to Flash ROM
I myself only use the Samsung USB drivers and ODIN never use KIES
or ...Check my signature and try SD formatter

Redmi 4X [Indian] No signal - emergency call only

One fine day, while changing sim I've lost the capability of phone to register on any network. Note I've not a tech geek so I've touched any of the hardware of the phone except some cleaning of dirt by opening the back panel.
When I tried to manually register a network, then it says "Can't register on this network, try again later". I'm unable to know whether it's hardware problem or OS issue.
Findings:
Phone can detect sim
It can detect nearby signal
Things I've tried so far:
Factory reset
Network Reset
using two different sim in both slots
Under *#*#4636#*#* > Turning off and on mobile radio power
I've downloded the latest ROM using inbuilt update system, because my microusb data port is damaged for a long time ago. So I can only charge the phone.
Download any official global recovery rom for your model and look inside the "firmware update" folder you will find modem fileb"NON-HLOS.bin". Extract this file to pc inside fastboot folder and open fastboot then connect your device in fastboot mode and type the following lines one by one.
fastboot devides
fastboot flash modem NON-HLOS.bin
fastboot reboot
Now your device will reboot and you get your networks.
Try this if you still having that handset. This method will work 100%.
Incase you need modem file only then feel free to contact me.
