[Q] N7100 Not Registered on Network

I just bought a GT-N7100 (International Note 2) from someone who bought it Taiwan a few weeks ago and when he got home, couldn't use it because he has Verizon. I have AT&T and don't mind not having LTE as I don't use data too much on the go so it was perfect for me. Although I told him I wanted the stock Touchwiz Firmware when I bought it, a MIUI ROM was loaded when I got it. When I inserted my SIM card it worked on the ATT Network and I had no issues for about an hour. I went to Samsung-updates.com to get the stock firmware and reflashed the phone to run Touchwiz.
Well, when I flashed the new/stock Firmware, the boot animation got stuck in a loop and I let it run for a good 30 mins before shutting the phone off doing a factory reset in Recovery Mode. After resetting, the phone booted up and I was able to set everything up and use my wifi at home, but I was unable to connect to any mobile network for phone calls or data (couldn't even call out to ATT customer service). Ever since I tried flashing the stock Firmware (I used ODIN to flash the zip I got from samsung-updates.com) I cannot connect to the AT&T network. It is not an issue with the SIM card as I've tried my wife's SIM with the same issue and my SIM works fine on her phone. I've since tried flashing other ROMs that are both Touchwiz based and CM10 based, including: Alliance ROM, MIUI, CyanogenMod 10, and Paranoid Android. Each ROM has had different APN settings that I have tried to no effect. I've also researched a few APNs that I've entered manually with still no results. The phone does me no good if I can't use it away from my house on a network. PLEASE HELP!!

Are you reffering to network as in data or network inc voice calls as well.

When I check the IMEI, it matches the box and the back of the phone except it has a /01 after it. So it reads 3536.......86 / 01. I'm not sure if that matters at all. But if not then the IMEI is good. The serial number also matches the back of the phone. From all the reading I've done, it's something to do with the EFS Folder but I don't really know where to go from here.

So from this we know your efs is not messed up and you have the correct imei set on the phone efs. From what I read so far you really need to call network operators and ask them by giving your imei number to see why your phone is not getting registered to the network. Do you think it might be blacklisted stolen lost phone?

To resolve this network/not registered prob, if you guys on 4.3 sammy.
Here is the solution
Flash this script

Don't reboot
Now flash this patched modem
https://www.dropbox.com/s/asr6y8tu9i4jzvv/GT-N7100_Patched_ModemMJ9.zip
Reboot, you'll see your network is back but it will go again if you reboot, to resolve this, after a while go to recovery again and flash Agni kernel. Link

Probably, since you've tried every possible solution through software. So yeah, might be a hardware issue.

Well the m7vzw is made for Verizon networks. If it works at all on any other carrier is just a bonus. Most people haven't had much luck getting this phone to work with other networks.

For now everything working fine except NFC. I got message from mywallet app that sim card isn't NFC capable.
On ViperOne I still can't make phone calls.
Anyone have idea how to change m7vzw to be recognized as m7?

[Q] Xperia Play R800i automatically reboot whenever wifi is turned on

Hi guys, I am helping to fix my lil bro's r800i.
His phone keeps restarting whenever I turn the wifi on and there is no phone signal. I mean visually the signal bar is there but no calling or checking credit balance could be done.
This happened since he did software update from sony's end to R800i_4.0.2.A.0.42.
Upon lurking xda, I found out these problems may be caused by the baseband.
Therefore I used flashtool to flash:
> R800i_4.0.A.2.368_World
>R800i_4_0_2_A_0_69_WORLD_1_8_1247_6176
>R800_4.0.2.A.0.79
>X10_V1_BLRelock
>and one other custom rom called GB something
I also tried to flash new kernel:
>LuPuS_zeus_Stock-gB+iCsv7-full
>PLAY-GSM-Advanced-Stock-vt
>ExtremeKernel_r3-480p
note: I wanted to try doomkernel but I couldnt find working download link
Other than that, I tried to flash only the baseband:
>Baseband -36
However, I couldn't solve the problems with the previous steps. I need advice from experienced users, thank you guys..

Try phone without sim or with different sim card
Do you know what firmware version was before you update it to .42?
You did right thing with flashing different basebands, but maybe it's hardware fault...
Maybe to try with lowest firmware version you can find?

The sim card is working well in other mobile phone.
So the wifi and signal uses the same hardware?
I will try your suggestion on the lowest firmware flashing and update later on. Thank you Bakisha.

As i know, wifi and network hardware is not related in hardware terms (but i'm not sure)
Also, try wifi in airplane mode (to see is it single or two separate problems)

SIM card not detected after flashing LineageOS 16

Hello everyone,
I have a pretty big issue with my HTC 10 which I installed LineageOS 16 on.
Last week I got the HTC 10 from my dad because he switched to a POCO F1 because the HTC has the battery problem (fast draining, phone powers off when trying to use camera etc.).
Since I was on a LG G3 which has the common display problem I took the HTC and didn't care much about the battery.
When I got the phone it was updated to Android 8 via OTA. I unlocked the bootloader, flashed TWRP, then LOS 16 (2019-02-02 build) and 9.0 gapps.
First I had no sim card because the G3 used micro SIM. Then I ordered a new one from o2 since it's free and has a 3 size adapter. When it arrived I tried to put it into my phone and was surprised that it still says no sim card.
It should work because my dad also has an o2 sim card and only one week passed since I got the phone so I don't think this is a hardware failure.
I have read something that I only can use Android 8+ ROM on 8 firmware but it was updated to 8 so it should have the 8 firmware, right?
IMEI is shown in settings too and there was something about flashing RUU to get to stock and having the 8.0 firmware.
If I really need that (which I want to avoid since I have to backup data and I have much data) can someone give me a link to Android 8 RUU?
I have a unbranded HTC 10 from Germany if that matters.
Thank you in advance,
VetrixFX

Being a custom rom with aosp base and a non standard/foreign provider, you likely need to manually set your apn.

I can't configurate my APN when the SIM card is not detected. There is no SIM card PIN prompt and it is a non-branded phone. My dad used the same provider as me with this phone but he was on Stock while I flashed it.

Oh, I see.
I would suggest going back to a stock based rom or RUU and see if it's actually working there.
Rather then relying on a custom based rom while troubleshooting it.
Could be a sudden hardware failure in the Sim slot/reader.

Flash the stock 3.16.401 ruu (its easy to find here as its linked a lot) and check if the sim works.

So here is the 2nd problem. I can't find a RUU where I am sure that is 99% compatible with my phone.

Also, I'm not real familiar with O2, but possibly the new SIM card needs to be activated...? (Pay as you go requires it, unfamiliar with other options)
I didn't see where you said if you tested the new sim in another phone. My apologies if I missed it.

I tested it in my Xperia SP and in my dad's POCO F1 and the PIN prompt comes. And the card is already activated.

Like I said, most likely the Sim card reader itself has gone bad or has lost its connection to the board.
