Samsung G930F (Exynos) with a BTU firmware. I am unable to run any of the USSD codes (even as simple as *#06# for IMEI). I am getting the "Connection problem or invalid MMI code". It is not a carrier issue since my wife's Sony Z3C runs them perfectly being on the same carrier. Any ideas how to solve it? Thank you.
Tried to run codes in safe mode as well with the same result.
I am on T-mo USA.

Yep, read that before I posted. Nothing works from that recipe. Thanks.
Fixed it by reflashing the newest firmware through Odin. Odd...

This happened to me before too, the way I got around it was using the phone info app from the play store, it can run the secret codes and check on other info on your phone. I also got around to reflashing firmware later which allowed me to just type in dialer again.
Hi, how are you?
I'm in big trouble and I can not solve it! I am with the Moto Maxx XT 1225 that is without IMEI, does not recognize the SIM CARD and the WIFI does not work I believe to be everything related to the lack of the IMEI right?
Already tried everything I went to 4.4.4 to 6.0.1 and nothing to solve, it shows the "baseband: Unknown".
Has anyone managed to solve it?
I'm hopeless!

Hi All,
I bricked my phone pretty badly couple of days ago. It was not booting and was not allowing me to go to the recovery and also fastboot was not flashing anything at all. Even unlock bootloader command was failing.
So, as a last resort, I flashed my NXT - L29 with the factory image of AL10 from DC-Unlocker Phoenix software. Also after that I restored the IMEI and all other stuff.
Problem is that after doing that my phone is not picking up any network. It was showing sim locked initially which I unlocked using the codes generated by DC-Unlocker and the phone now is not showing locked to carrier but still it is not picking up any of the service provider's network. I tried Airtel and Jio (I am in India). Strange thing is that it is not even listing any networks when I go and search for them manually in network options. Not even in 2G or 3G specific modes.
To overcome this issue, I debranded my phone to C636 and C185 as well but the result is the same. No network.
I suspected that somehow the bands got changed from TD LTE to FDD LTE which is causing the issue as in India all 4G rpoviders use only TD LTE right now.
Now my question is that is there any way to get back to the TD LTE and should this effect 2G and 3G coverage as well.
Any help will be hugely appreciated as the phone is right now a brick even if it boots up and functioning fine. :crying::crying:
I don't know much about dc unlocker but do they have l29 factory image to flash?
What about the baseband in about phone is it showing correct and ur imei?

They do not have L29 factory image.
However, I already restored the imei and unlocked everything.

What was ur original region l29c...?
Did you use srk tools to debrand?

Think the oem info is what is causing the problem.

The code in the link does not work on mate 8. May be they have just assumed that it should work and it might be a generic code. I found that link when I was looking for solutions and many more like this but they do not work. The codes mentioned on the most of the tutorials are not working on mate 8. I think USSD codes are partially disabled on our phone.

dont waste your time guys, dbrand or flashing original firmware will not solve the problem i ve tried all possible ways to make it work with no hope.

Contacted the tech support of DC as well. As per them this is a limitation of firmware flashed. Only solution as per them is to flash L29 factory firmware which they do not have. Or contact huawei.

Have the same problem with my al10 and a g8 rio-l01
I repaired the al10 like you and flashed with the stock china rom (ota update work) but no service, the working code in al10 is *#*#6130#*#* not 4636 (you will se the phone is in VoLTE mode) but you can't do nothing, there is no service (i think we need to flash the radio)
For the g8 its an mea version repaired by the same way but this one got more problem it boot but with factory run mode and no service too
Hope we will find a solution (asked dc unlock team and im waiting)

Hi all,
I was running a custom ROM for a while (KangVIP) and decided to revert back to stock. I missed it up and I bricked it. so kept trying several methods and finally managed to make it work via dc-unlocker. However initially I wasn't sure which was my original stock rom version. I'm in the middle east so I tried all the different nxt-l29c185xxx versions. nothing worked out, so I tried the second method of dc-unlocker using NXT-AL10 factory firmware and the phone worked. so I debranded the phone using SRKTools, then I flashed different l29c185 stock roms and it seemed that it worked out. However the issue I'm facing now is I'm getting SIM network unlock message when restarting, which shouldn't be the case since the phone originally is unlocked when bought. so I checked through the manufacturer mode and the Bootloader version there shows NXT-C900B120-fastboot
I'm not sure what this means. I tried several ROMs using SRKTools and ItalianKnife and still this didn't change although the build number in the phone changes.
any ideas how to completely revert this back?
appreciate your help

Hi.
As you said you are on B200 so your phone is marshmallow and it is good because SRKtool just can rebrand Marshmallow version.
My suggestion is to use SRKtools and rebrand your phone to correct brand (NXT-L29C636 or NXT-L29C185)
If you do it correctly, I bet it will work.
Have a nice time.

I've used dc-unlocker to get passed the unlock code. Now I have the phone on L29C185B520; however everything in the phone is working perfectly except the sim; there is totally no signal. I have checked the sim in other phones and it's working fine.
I took the phone to a Huawei repair center and they said its a problem with the mainboard which needed to be changed and it'll cost around $200 USD
I believe it's a problem of modemvm partitions. is there a way to fix it?
Can anyone help me for convert global rom to xperia 5 ii. Both version AS42 and AS72 cannot flash because about storage is 256gb while my phone is 128. Unlucky, I try many version but some of them cannot wake up just still at corruption. On the other hand, if it wake up successful but cannot detect sim card. Also, I try to mix rom likes delete .ta include inside boot file and persist and oem file but it still corrupt. So anyone have solutions for this problem ? Thanks in advanced.
I think you can copy the partition folders from the softbank version to international then flash via newflasher
I have a docomo version and can't flash to another firmware

Hey did you flashed the global rom? If you did see if it lets you unlock the bootloader. If it does then you can just flash a custom rom and get sim card support using root. If my method works inform me. I will do the same thing.
Hey. I unlocked the boot loader with q unlock tool. My doubt is that any global rom comes with single sim support?

That's a really good deal. I got mine at 180$. But if there was a free way i could root my phone -,-. Volte works on my phone flawless without global rom.
If just you want to have android 12, you can flash SOG02 KDDI.
Did anyone manage to get android 12 running on A002SO(SOFTBANK) ? Whats the best solution and option? Or what's the closest firmware to A002SO 8/128GB single sim or any cheaper option for us to get bootloader unlocked? And even of we opt for custom roms wont the single sim cause issues?

Why you need Global Rom ? For Volte Vowifi ? For that you just need Global Modem Configuration which is very easy. Download SEA firmware and copy Modem Fils to Sogo or SoftBank or whatever your device is. Just copy these file to your firmware and flash it. That's it I will get Global Modem and 4 singles issue will be solve. Plus if you want Volte and Vowifi then there is simple track u have to run one small app and you will get everything. Personally using SOGO2 Xperia 5 ii in UAE and I got everything except 5G network. Trying to solve it also. Soon INSHALLAH.
