Redmi 4X [Indian] No signal - emergency call only - Xiaomi Redmi 4X Questions & Answers

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.

phone lost IMEI number !

dear all
i have tried everything and i think i bricked my phone.
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
the problem is the phone wont recognize the simcard , everything else is normal.
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

Can't seem to get adb to detect the phone -> so no unlocked bootloader

Or.. I've installed the usb driver package from LG. And I can go to the power off-> charger mode, and get contact with the "modem device", or whatever it is they're using, for a short while. But that won't help me get the bootloader unlock routine to work, it just gets stuck in "download mode!!!!", presumably because it needs to do some weird online routine as well, that I didn't know about, or it needs to download something via gprs, or ... and so on. And in phone mode, the serial number/device doesn't show up. (I tried removing the memory card, on the off chance that having the "mass driver" device turning up would mess something up, but no luck.
Anyway. So is there a trick here, to get adb to detect the devices, or to make the "modem device" mode have precedence, or something of that sort? I'm a bit reluctant to try disabling some of the devices, even if that would work, in case there's something else I don't know about being run half-way as well.. will the mode change on reboot, and I'll get stuck with a brick..?
Have anyone else had the same thing? I can run the pc-suite and the lg support tool just fine. But it seems that what happens is I'm able to have the adb tool detect the serial number for a very short time, and then it disappears and I can't connect to it again. Therefore, no bootloader unlock tool init..
I had the same problems back a while ago.
It got solved on the 262-000 Bootloader unlock thread.
I think you need the newest adb and fastboot drivers
and disable the modem in system settings of your pc,
but search for the mentioned thread and look it up there
Hope you get it working

Phone bricked, please help.

I tried researching for information on this but wasn't able to resolve it. Basically, i have the same problem as here; Flashed a ROM, but after flashing it I found out I did it for the wrong model (5833 instead of 5803). When flashing the rom I wiped Dalvik, Cache, Data and System, and now I'm stuck at the Sony startup screen. It won't let me go into recovery mode.
I too tried to flash stock using flashtools, but it tells me "INFO - Device Status: NOT FOUND". I tried using the Sony PC companion restore function but I get the same problem, telling me there's no phone/device connected.
EDIT: I tried following the steps from this post, but I'm still stuck at the Sony loading screen.
Is there anything to do?
Have you tried the following with the sony companion?
Shut down the phone completely by pressing power and vol+ until the red led lights up and it vibrates a few times.
Now without connecting the phone you go to pc companion, update > repair my phone > select the model > check the boxes and go forward in the menue until it promts you to connect the phone. Your internet connection of your pc should be working for this.
Make sure you have the original cable or another high quality cable, blow into the micro sd slot on the phone in case there is some dirt in it. Might also check it with a light for some foreign partikels stuck in there.
Oke, assuming there is no actual crap in the micro sd slot, when pc companion prompts you to conntect the phone you do as it says, you press vol- and connect the phone to the pc at the same time.
The process takes a very long time so be patient or do something else while its repairing. If its not working try one more time.
If its still not working try to get it shipped in for sony warranty repair by calling the hotline and lying about your abuse of the phone and just say it suddenly stopped working.
Other options are to pay for repair at a phone repair shop or sell the brick.

First see if fastboot devices command gives your phone serial no. or not. If yes then it's a good news, flash recovery again, boot into recovery, flash rom and boot system.
If not, you may need to update your device driver in PC.
First possibility: your fastboot driver in pc needs to be updated.
2nd possibility: Some phones have EDL mode (emergency download) , google if your phone has it. Then you can probably use some tool to restore your phone from this mode.

No network connection on x522

Hello,
I have a problem on my father's x522. It ran out of battery and after a full charge it couldn't find any sim card. I've restarted the phone in fastboot mode and applied these commands:
fastboot erase modemst1
fastboot erase modemst2
After restarting the phone both sim cards were working, I could insert the pin numbers, but the phone couldn't find any network (wi-fi was fine). I've noticed that the IMEI numbers were gone so I've restored them using QMSL IMEI & SN Writer, but still the phone couldn't find any network. I've also tried to find netowrks manually but I kept getting this error: "Error while searching for network".
I've tried to flash new roms (the phone was on a stock 23s if I'm not mistaken) and modems but the phone still has the same problem. Right now I'm on a Small EUI by Ariel, the baseband is mpss.ta.2.1.c7-00008-8976_GEN_PACK-1.64611.1.68083.1
What am I missing? Is there any way to make the phone working again (before telling my father to buy a new one...)?
Thank you.
Hi, I have the exact same problem, did you manage to solve it?
my problem is the same try everything all in vain decided to to open up my phone found that the antenna cable is to near the screw and it is squash so that is how i solve it by tucking the cable away from the screw area.mine is new btw changing diferrent sim also did not help so my problem is hardware.

No.
I've tried everything, ROMS, modems, QCN backups, voodoo rituals, but still this phone doesn't connect to the mobile network.

I think I solved it by doing these steps:
1. Put the phone into Airplane mode (I'm not sure this is needed, but it doesn't hurt)
2. Go to Settings -> About Phone and tap on "Build Number" until it says you are in Developer Mode (~10 times)
3. Go back one menu, and right above About Phone there should now be an option for Developer Options, go into that
4. Turn on USB Debugging
5. Connect the phone to your computer and type "adb shell" in your CMD window
6. Run the following commands in adb shell :
pm clear com.android.providers.telephony
settings put global preferred_network_mode 9
settings put global preferred_network_mode1 9
settings put global preferred_network_mode2 9
7. Turn off Airplane mode
8. Power off and Restart the phone
9. Open up the settings app, go to the mobile networks panel, select "Preferred Network Mode" and change it to "4G"
10. Input the appropriate APNs for your specific carrier
You can try other modes, here's a list I found: https://android.googlesource.com/platform/hardware/ril/+/master/include/telephony/ril.h#228
I hope it helps.

Did you try with the rest of the mode numbers? There are 18 more.

(FIX)Press any key to shutdown, phone dead, fastboot not working, +2 days without it

I was texting, using xiaomi.eu rom stable lastest, stock kernel, no root.
Gallery stopped, then camera, whatsapp closed, instagram gave black screen...
I turned the phone off and then turned it on, bootlop, so I went to TWRP and wiped all partitions and also formatted data. I also did a selinux fix contents or something like that, I flashed another recovery, a custom one via zip and then phone died, mi logo and rebooted, only fastboot available.
When I use fastboot and connect it to my pc it gets detected as kedacom adb automatically, I tried lots of drivers, uninstalling any driver and installing google drivers and lots of things, got ADB and fastboot 15s installed, I also tried different cable, other pc, 2.0 ports, 3.0 ports, other Windows, virtualbox, doing fastboot flash recovery twrp.img with waiting device and then connecting...everything I've seen and know. I bricked my phone and other phones more than one time, and managed with almost no issue to fix it, but now i'm just lost.
I get Press any key to shutdown, on the left top corner of the phone, I do the following:
fastboot devices(gets detected by fastboot)
fastboot flash recovery twrp.img(instantly I get press any key to shutdown)
I can't do anything, it's dead, any tips or something? Thanks guys.
I needed 13h in total to fix it, so I wanna share what to do, the fix is in the post, scroll down a little bit and you'll see it. Hope it worked.
I fixed it finally, if anyone wants info, pm or reply
I need to tell this honestly, you should share what you did and how you did, so you can help anyone anytime if they encounter this problem anyhow. They can use this thread as a guide and don’t need to start a new topic and we save the forum from flood messages and topics. Thanks in advance.
THE FIX
It was very hard and tricky, but possible, you'll need a computer, usb data transfer cable, type c to usb, and a usb mouse, you'll need your device to be unlocked first, if it's not unlocked, I can't help you.
I used Tool All In One by Mauronofrio, installed drivers and with phone in fastboot connected it, if I press check, it will reboot and fail, you have to go to recovery flasher, if no recoveries are available, then download and put it on the same folder where the tool is. Go to recovery flasher(not zip one) select it, I recommend mauronofrio one, the lastest, and then select when going to flash flash and boot, it should be black screen with waiting devices and the phone with the press any key thing, then just disconnect the phone from the cable, restart it to fastboot and connect it, it should boot, you'll have mi logo or fastboot for a minute or 2 and then it will boot to twrp, but you may not have your touch working, just connect the type c to usb adapter and use a mouse, you should be able to use it, go to wipe, wipe all partitions, then format data and connect the phone back to computer, if it does get detected, you'll see the phone in file explorer, so you'll be able to move any files, move any rom to internal storage, use then the usb adapter and with the mouse, flash the rom, reboot and everything will work.
IF IT DOES NOT GET DETECTED, Go to recovery flasher(not zip one) select it, I recommend mauronofrio one, the lastest, and then select when going to flash flash and boot, it should be black screen with waiting devices and the phone with the press any key thing, then just disconnect the phone from the cable, restart it to fastboot and connect it, it should boot, you'll have mi logo or fastboot for a minute or 2 and then it will boot to twrp, but you may not have your touch working, just connect the type c to usb adapter and use a mouse, you should be able to use it, partitions allready wiped, so just put the rom file if it was deleted and flashbe sure that under partitions is MTP enabled, if it is and it still does not work, just go to reboot and select recovery, wait for it to boot to recovery. If it goes to fastboot and does not work, When booted, your twrp touch will be working again, if not, just flash another one.
There are other options, trying usb hub, 2.0 ports, a non amd pc, uninstall drivers and install google ones with internet disabled all time when flashing... But this is the one that worked, if anyone needs help, I can help you with Discord or pm.
Thanks for sharing the fix.
