No Wifi and Sim Card Service - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hello guys, so about 4 months ago I flashed HentaiOS, and after that I flashed wrong type of kernel.
After that I restarted to the system and my Sim Card and Wi-Fi didn't work, My phone doesn't find any Wi-Fi and it doesn't recognize the Sim Card. Is there anything that I can do? I live in Iraq and I brought to Xiaomi Iraq and they said that I have to change the motherboard, it costs 120 dollars to repair. Is there anything that I can do without changing the motherboard? Thanks for answering

CanĀ“t use simcard: `emergency only`

Hello,
I have a Samsung Galaxy Ace S5830 for 3 years now. I flashed different roms and did root my phone in all these years. But... now i received a new sim card which works well in other phones but NOT in my ace. So that must be a problem with my ace.. I just flashed back to the stock rom (XEN - Netherlands S5830XENKS1) via ODIN but the problem is still there, i can't use my sim-card: "Emergency only".
I already wiped data and cleared cache, hard reset... nothing works. What could i try to have my phone back working with sim card so i can call, sms and use my dataplan. My phone have no simlock i checked and the IMEI is also the right. The one shown by #06# is the same as printed behind my battery. I also received a new sim card from my provider, but this one also has the same problem.
I hope you guys can help me out! :good::good::good:
UPDATE 1: I tried differend sim cards in the phone. I always used to have T-Mobile as provider. All other simcards are not working, theyre showing up for a few seconds and after that it says: Emergency calls only. When i put in a T-Mobile sim card the provider keeps displayed, so it looks like my phone only works with a t-mobile card. But it's not sim locked, because i also used differend sim cards before..
UPDATE 2: Now my simyo simcard also connects and i can sms, call and internet. But after a few seconds/minutes again the message: Emergency calls only
WHAT COULD THIS PROBLEM BE??!!??! Strange.............. I really hope someone can help me out this

I think your device has a problem to make contact with sims cards, so your device have a trouble accessing read and use sim cards... You can send your device to the support service, to check or try to fix it...Have your warranty still in effect?

Hello, thanks for your reply! No, my warranty is not active anymore. My phone is 3 years old. Today i went to another city and could call and sms the whole day. No internet. When i came home, i received again the message: emergency only. How strange.. I also could'nt find a good rom or firmware to flash back my phone to the full original software and firmware... Can someone help me on that? I need the newest firmware for the samsung galaxy ace s5830, netherlands version. Or maybe a custom rom which is the most used and stable version. I would like to exclude software reasons, so it might be a hardware problem. But i think it's a software fault cause of the different roms i tried on the phone.

It's very strange.. here it is Netherland's fws, try flashing your device if you want, but I've never heard that strange problem xD
http://www.sammobile.com/firmwares/1/?model=GT-S5830&pcode=XEN#firmware
Always when you'll change your custom rom do the 3 wipes to leave your device as clean as possible
Thanks for your fast reply! I did this firmware already yesterday and also wiped dat and cache + recovery... The problem keops showing up I will try this same firmware again and let you know if there are changes or not.

You can also flash whatever fw you want from EUROPE, because your device is unlocked in order to check your sim's trouble

Again flashed the original firmware to my Ace. Wiped data and cleared cache. Everything works..... Except... the simcard. Can't call, can't sms and can't make an internet connection. So, still the same problem. The sim works well in another phone, and another simcard in the Ace gives also "Emergency call only". So it HAS to be something with my phone. Someone any idea's i can try / check now i'm very sure it's a phone problem with original new flashed firmware? I hope it's not an hardware defect......... how can i check?
UPDATE: The only simcard which works well is a T-Mobile prepaid simcard. All other simcards sometimes shows up, but most of the time not. The more strange fact is today: I went to another city and was able to call and sms the whole day. But no internet. When i came home, i received again the message: emergency only. This is so strange and makes me very sad. The phone is simlockfree, WHAT COULD IT BE So strange............
Tomorrow i had internet connection, could call and sms. My provider was shown on the screen and nothing wrong. But unfortunately just for a few minutes... No stable connection.
Someone any idea? :crying:
I too faced this problem once.....What I did is that I just formatted the system , wiped data , cache , sd ext and dalvik cache and then restored a backup of my earlier ROM in which the Sim was working ! And it was fixed....

Thanks for your reply! I did your trick but unfortunately... It did'nt help. Very interesting thing is, while i'm traveling around there is no problem, but as soon as i stop driving and walk around, the problems are back. Someone any idea on this strange problem? :crying:
cant access sim
until now this is problem...
why they cant fix this important setting
better to back to stock rom.
is does all are working
yeah CM's are good but still
many bugs and error
like this one.
not STK, sim contact save
and show in contact app
i hope they fix this one asap
You dont have any choice other than visiting the service centre. Yes they may charge you a good amount but seems none of the methods are working.
Also try contacting your service provider maybe thay know the exact reason.

GT I9305 on Omni rom not recognizing UMTS sim cards

Long time omnirom user here with an issue I cannot find a fix for.
In my country there's a cell operator called RCS-RDS that has always had very good rates and unlimited 3g internet but, up until recently, very bad coverage. I have used 2 sim cards from this operator whenever I was in their coverage area for years now without a problem.
Last month RDS, has signed a national roaming agreement with VODAFONE so that you can use their network for service whenever you're outside RDS's coverage area. To use this national roaming service however, I had to replace the sim cards I had from RDS with new ones which, they say, operate in the UMTS 2100 band. I've checked the I9305's specs, and that band should be supported without a hitch.
Problem is however, that if I try to use either of the 2 sim cards, the phone gives me a no sim card error message and will behave as if there's no sim in the phone.
I'm using the radio recommended by mccamblesmith, the I9305 omni rom developer, in the omni rom development thread, and I have tried flashing every radio I could find, from the newest 4.4 radios to some very old 4.3 ones, but no change, and I've tested the two sim cards on other phones, including an S4, a beat up old Allview, an even older and more beat up Huawei U1220 and a 3G USB dongle, and both sims worked flawlessly on all of those.
I've also tried getting help on omnirom's irc channel, but the place is dead.

i understand the issue here, but dont know how to fix it easiest way without loosing all your data and personal stuff etc.
it seems the issue is not modem related but i think its related with the roms settings you applied but dont know what exactly. all i can say is make a nandroid backup to external sd of current rom and flash back your official stock firmware with odin, root and install recovery and flash omni again, then try the sim cards again. if it does not work you can always restore the nandroid backup from recovery.
i hope this helps

Due to a HDD failure a while ago, I no longer have the nandroid or the stock rom I saved from before I CFW'd the phone. Would changing to something like SlimROM or the likes help?

well you can always make a nandroid backup at any time in recovery mode, you know that right? cant tell if changing CFW will help but you can try it..
Edit: if i were you, i would make backup and put anything else important in internal or external sd to my pc temporary and wipe everything system/caches/dalvik/internal memory and then flash another custom rom or flash back omni again

Here you go, download mod 7 and flash with odin maybe you will need to flash the custom recovery of your choice over again and then you can flash the supersu update zip in my odin guide (in my signature) to get root acces.

[Q] Lost network & relocked BL?

Hello,
I've a weird problem with my Xperia SP. Today i wanted to get back to rom based on stock rom to get miracast feature.
I downloaded newest existenz rom and williams kernel for stock based roms. Installation went fine system booted ok and everything worked fine. After some time phone turned off and didn't wanted to start. Only flashmode worked. I've decided to download stock .205 CE1 rom and flash it.
It booted up, sim card was recognized(had to write PIN). After that network was not found. Signal with red "X". I've tried to manually register to network but i could not.
Next thing is that after flashing stock rom fastboot mode stopped working. Service menu shows that Bootloader can not be unlocked even that it was unlocked before and flashtool(BLU option) shows that it is still unlocked. Flashtool also shows Bootloader: NOT_ROOTABLE.
I have actually no idea what have happend. Now i'm installing stock rom using Sony PC Companion but i think this wont help for network problem.
My main network is PLUS GSM(Poland network).
Could sim card die? It is old type card (almost 10 years) and i had to cut it manually to fit micro sim for the phone.

Use flashtool to flash stock firmware by ftf file. Here:

Use an older one and if that does not work, try one or two more. Hopefully, that will help. Best of luck!

Does it matter which country is it for? I can try some of them but i think that won't help. I've checked other sim card and it was recognized but didn't even ask me for pin. Weird Oo.
If nothing helps i will just flash stock firmware with SEUS and let sony service take care of it, hopefully. Phone still has guarantee.

Regions perhaps. But the thing that does not make sense it that that why did it work before and not now? It should work. Anyway, my SIM was mini too. I, too, had to cut it. It works. Or possibly contact your service provider maybe something is wrong with the SIM. They might have have locked it or something?

I've reflashed stock rom using SEUS and sended phone to sony service. Hopefully they can help. Be careful with Williams Kernel for stock roms. This may be a common bug.
For anyone who had the same problem. Sony exchanged my whole phone with information that mainboard was broken. They said that phone could not be fixed.
Good luck
PS. Topic can be closed i think.

4G is dead, QCN file needed

So i send my first RP2 to warranty because my proximity sensor was dead, it went good and Razer sent me a new device with UK branding (Three) after some time of using it I flashed global version, after this on 4G i don't have Internet connection I also can't send or receive any SMS, on 4G+ i need to wait some time to receive or send any SMS but mobile data work perfectly, 3G is working without any problem. I tried to change a SIM card and flash back UK version but problem still remain. I also tried using GSI without any success. Last thing i tried to do was make full backup in QPTS but it stops at 99%. Next i what i did was EFI and Modem backup in TWRP, after this i tried Rog Phone 2 QCN file just to see I can send it to my device via QPST fortunately it worked(of course because it was for Rog phone 2 i had no Imei or signal). After this i restore an TWRP backup with 'success' (Stil RIP 4G). So what i want to do is get QCN file, put my own IMEI and see if 4G is working again.
And of course, sorry for bad English.

I don't think this phone have radio partition (at least it don't exist inside official RP2 images) I know about modem partition and I flashed it a lot of times (stock and three) without any success.

I originally ment modem, but I think the QCN file is part of the vendor partition, which i think if you modify will cause problems. I'm interested in how you change it as i'd like to do something similar to another phone.

I will send link in private message because XDA don't allow me to paste it here, there you can read about process of backup, restore and repair of qcn, it's not in a vendor partition because it stores a IMEI. (Razer phone 2, actually have 2 IMEI numbers)

Did you ever find a QCN file ?
my phone stopped seeing the network, I have tried different sim cards from my country and sometimes it finds the network and works (no 4g)...
but, If I insert a sim card from Digicel Panama it works great at LTE+ mode.
any suggestion ?

Question IMEI gone

Hi guys, I'm in a very big trouble, since I was trying to rollback yesterday from A13 Oxygen 13, in a converted NE2110 Chinese model flashed previously with NE2115 Rom, I was having ridiculous battery life with the rom, so I want to test the European NE2113 rom, I've download the NE2113 Rollback package and applied with the local update apk provided by Oneplus, the procedure was apparently sucessfull, but SIM isn't recognized when A12 NE2113 rom booted, I've thought its a band relates problem, so I've flashed black the NE2115, but stills the same, I've get in to the IMEI numbers, and both are NULL and Baseband is blank.
I'm in Ecuador so it's absolutely impossible for me to sent the phone to Oneplus Repair services, and even if it was possible I doubt a lot they can take the phone, because it's bootloader unlocked.
If anyone have an idea about something I can do, I'll really appreciate that, it's an expensive phone and I've put a lot of effort to buy one trought and auction sale and even played to import from United States, so if you think there any hope available please share with me, I've read the one post here with someone who still needs to repair the IMEI seeing it's impossible for now, but at least I have to try to restore the phone, I can't have a media player unusable SIM phone of almost 700 bucks.
