[Q] Help needed, stuck after updating firmware (emergency call)

Hi,
Well my device which is S5 mini g800f working fine, since I have changed the firmware which was old like build on july so I tried to installed latest, but now there is emergency call showing, also I have tried manually and automatically to register on the network but it says unable to register to the (---network). I did it coz my device was not showing LTE network. However my sim supports the 4g and was working on S4 i9505. I have searched on Google and look out many threads on XDA but no success until now.
The biggest mistake was I didn't looked the firmware which was already there and was running with 3g support. I have tried these EUR-G800FXXU1ANL1-20141226162921, SER-G800FXXU1ANG1-20140709112536, MAT-G800FXXU1ANI3-20141218172328. Then I have installed Custom Lollipop but no success was there too.
So now any pro's here who can understand my problem ? My imei is showing, is there any procedure where I can put the imei and it will let me know what was installed on stock :crying:
Sorry for being noobish..

Please any buddy give me suggestions that what should I do ? Or should I look in the specific section of XDA forums ?

What do you mean by this? IMEI showing or Not?

Its is mentioned mate what I have written, I said my imei is showing that by dialing *#06# I can see it, because there is a problem where the efs folder corrupted or gone you cant see imei or imei appears to be in these digits 00000 especially by installing custom roms. Anyways my only motive is that I know the imei and how ever I can see it too, so is there any procedure where I can put the imei to the website and see what was installed on stock. Because I dont have the box so I dont know which firmware was there when I installed another rom to get LTE, because it was working properly as I said in my earlier post.
Problem is due the baseband I am pretty sure which is not matching, this is the reason because I cant connect to the network---error msg (Unable to connect).

The baseband firmware is included in the firmware packages that are available on sammobile (.tar.md5 files). If you flash the firmware package with Odin, also the baseband firmware (contained in modem.bin) will be flashed.
If you have problems with a newly flashed stock firmware that were not present with the original firmware it might be because of one of the following reasons:
You flashed the wrong firmware. I don't think that the version name of the original firmware is stored somewhere. Instead check sammobile for the correct one: select the correct phone model and your country. EUR, SER (for Russia), MAT are country codes, choose the correct one for your country, the search function on sammobile will help you with that. You can also try Kies for restoring the firmware. Maybe that is able to determine the correct firmware according to the IMEI or some other information stored on the phone.
Maybe your EFS partition was changed and corrupted. The EFS partition is the partition that contains the IMEI and other information like calibration files that are specific for your device. If any of the files in this partition is damaged, the phone might not behave correctly. If you flash another firmware the EFS partition normally is not changed.
Your hardware is defect.
I guess that you simply flashed the wrong ROM. Otherwise the problem will be hard to fix.

IMEI and Baseband Unknown HTC Desire 626G+ Dual

I've flashed a recovery.img file of a wrong variant with Official TWRP App and lost my IMEI and Baseband as a result.
Thinking that it'll be fixed by flashing the stock recovery back, I flashed the stock recovery. But it results in nothing.
No IMEI and Baseband yet.
Tried to change IMEI by Chamelphon, MTK Engineering Mode. But they failed.
Deleted the nvram folder too, but nothing seems to be working.
Any idea what to do next?
Samsung stores the IMEI thing in their EFS folder, where in HTC?

I brought my device to a service provider and he repaired my Baseband and IMEI with his Infinity Box and it's fixed then after.
But it now shows CID Error warning! Going on well with this warning so far.

I've, however, already been to this site and tried almost 10 of their custom ROMs just to stay on with the RR-5.8.8 finally. And the cool thing is, custom ROM doesn't give me any CID error.
STOCK one gives always, though. :crying:
Wasn't sure enough if I was supposed to share external links here or not.
Thanks, anyway.

Missing WiFi MAC and IMEI - Mi 9

First off - Mods, I have the original box and sticker IMEIs if needed as proof.
I have been flashing between AOSP and Stock trying to fix a Microphone bug on my phone (see previous posts), when all of a sudden my phone will no longer connect to Network (IMEI unavailable error)
I went through every QCN backup + editing I could think of, even using my friends Mi 9 that we both bought from the same place in China as a QCN backup + my IMEI edits.
Everytime I edit the QCN and load it, the phone just boot loops immediately shutting down upon OS load. Using MiFlash back to stock didn't work, and I had to flash Evo X rom to get it to boot normally now, but I"m also missing WiFI MAC onto of my IMEIs.
I seriously have no idea what to do. I've tried every IMEI editing tool or Hex Editor in the book to put my original IMEIs back in to no avail. What am I doing wrong that cases it to restart loop when I push my updated QCN file?
Thanks in advance - Can provide whatever else you need.

As i understand you have China version of Mi 9, saying: "MiFlash back to stock didn't work" you meаn you have flashed official xiaomi china FASTBOOT ROM and it did't work?
Then i afraid the problem is deeper then in the ROM. Because by flashing stock fastboot ROM you flash everything that possible to flash, ROM and all images, with all setting like it was from the store.

Correct. Reflashing China ROM in Fastboot does not fix the problem. It fixes the bootlooping but not the IMEI issue.

IMEI unknown after flashing custom rom

I flashed Android 12 custom rom which messed up my baseband and now IMEI is shown unknown (wifi, Bluetooth, mobile network not working)
So i rolled back to my previous stable rom -
PixelExperience_Plus_rosy-11.0-20210313-0535-OFFICIAL.
But still no network, wifi and Bluetooth.
Please help me.
I tried one way as below but not sure if it is correct -
I tried a qcn file downloaded from some site and updated with my original IMEI and tried to restore it using QPST (QPST detects the phone successfully) but it gives some error (phone sent invalid reply)
Please help me with the easiest option.

Question Can someone give new NVRAM and NVDATA image to me for fixing IMEI problem

I lost my baseband and IMEI after flashing Redmi Note 11R from China Stable to EEA Stable, so I follow guides on Internet and tried to reflash it with SP Flash Tool. I use "Format All+Download" but after that, I can't boot into system but always fall into MIUI recovery 5.0 with "NV data is corrupted" message.
Then I tried to use ModemMETA, but when I press write button, I always got operation timeout error, so I think maybe those partition were damaged.
Will flashing a new image fix issues?

I can give you that files, but it won't help. If you delete nvram - than your phone will not call any more, how to fix that - only on service firmware, but when you upgrade it to miui, no phone calls. I have the same phone, same problem, and no solution. Maybe in some month

Thanks for your helping, now it can at least boot into MIUI, not recovery. But the problem is ModemMETA tool now stuck at "Connect to MD" with good nvram files. Does that means I can only use the tool with corrupted nv data? That's weird. Also, I still getting unknown baseband and IMEI with China ROM, what version and region was your MIUI when you backup those files?

I have India, but it won't help you. If you want to recover your phone, you need to flash ENG rom(Format + Download) to use Meta Modem, then write only second IMEI. I have ENG rom if you want https://disk.yandex.ru/d/HFA-nWmHW8x1Kw
But then when I come from ENG to Stock - my baseband lock, phone no detect simcard. If I flash another modem, phone see simcard on stock, but no calls. I think it's becouse of baseband from nvram, nvdata + md1img that can't be applied on new phone with out change of Imei in that files, Meta Modet can't change IMEI in that files, it can only work on empy nvram, nvdata but with that files my phone don't calls.
So you need to flash stock and use special soft life Unlocktool to repair IMEI, I will pay some guy to fix my problem becouse I don't have solution for that. I spen about week on that problem in Internet - there is no solutions yet for that mode, Redmi Note 11E, 11R, 10 5G (light).
