[Samsung Galaxy S7 Questions and Answers] Droiderat:
Your problem is a consequence of the T-Mo acquisition of Sprint, and the resulting network reconfiguration which occurred in early 2021. The legacy Sprint bands (25, 26 and 41) do not support voice calls when connected to LTE; when connected to one of these bands, you must use VoLTE (which is different from LTE-Voice). And, therefore, when connected to one of the these bands, you will see "Not registered on network", although data will still work.

You can verify which bands you are connecting to by using the apps LTE Discovery or Signal Spy.

The solution is to enable the SM-G930F to use VoLTE.

-- Backup the data on your phone (you will lose it)

-- Download the Windows software "Samfirm", and then use it to download the official Samsung ROM for "EVR", and install it using Odin.

-- Install TWRP (I use twrp-3.5.2_9-MoRo-1.6-herolte)

-- I suggest following that by immediately installing the Alexndr ROM: https://xdaforums.com/t/rom-g930f-fd-alexndr-u8eue1-devbase-v7-4-encryption-support-jul-10.3592914/ This is a debloated version of the official ROM, so everything works properly. Be sure to follow the instructions for keeping your CSC (in this case, EVR). Root the phone using Magisk.

-- I suggest using the ThundeRStormS kernel, which is MUCH more stable than the kernel in the Alexndr ROM (the stock kernel reboots randomly; the TS kernel does not).

-- Reinstall your data; reconfigure phone.

-- Download the app IMS Settings to enable VoLTE (you will need to re-implement these settings whenever you reboot).

You will find after doing this that VoLTE (and T-Mo or, in my case, Mint) works perfectly, and you will be able to connect to all of the bands now supported by T-Mo and the SM-G930F without issue.

Will these instructions work for AT&T also? What is the correct site for downloading SamFirm?
[Samsung Galaxy S7 Questions and Answers] Droiderat:
They likely will (but I don't use AT&T, so I can't confirm).
[Samsung Galaxy S7 Questions and Answers] Feenix0:
Thanks! Actually, duckduckgo is my friend ;), but I only saw results for SamFirm, but there were several different ones and I don't want to use a copycat site that may have tampered with something. I think I'm safer trusting info I get on xda.
[Samsung Galaxy S7 Questions and Answers] Droiderat:
DuckDuckGo uses the Microsoft Bing search engine. My version of SamFirm is 0.3.7.1. I don't know which site I got it from.

When I open my SamFirm app, there is now a notice which tells me there is a newer version of the software, called SamUpdate.. See https://kfhost.net/firmware/samupdate I haven't yet tried the new download method, as the SamFirm tool still works.
[Samsung Galaxy S7 Questions and Answers] Ritor:
Thanks for the thorough response! I actually used to use the EVR csc in years prior, but switched to BTU due to the EVR bloatware. Does it really make a difference ?
[Samsung Galaxy S7 Questions and Answers] Droiderat:
I don't actually know. I researched VoLTE, and the suggestion I found was to use EVR. I didn't try using the IMS Settings app with BTU (my original CSC). I am not aware of any bloatware in EVR, but I immediately overwrote EVR with the Alexndr ROM, retaining only the EVR CSC. So, if EVR had bloatware, I wouldn't know.

I recorded the steps I followed, and I can attest that it works. There may be other solutions.
[Samsung Galaxy S7 Questions and Answers] Ritor:
I understand. When I originally bought my G930F, it had a latin american CSC. I first tried EVR from SamMobile, and it came with a bunch of uk carrier specific bloatware. I later installed BTU after reading it was the generic UK csc for non carrier branded phones.

[Samsung Galaxy S7 Questions and Answers] Feenix0:
Finally digging into this process now that I have a temp phone.

After Odin failing to flash with either the BTU and EVR, I started writing this post and took a picture of the download mode screen. Contrary to everything I saw in my phone's status and information apps, the download screen showed:

PRODUCT NAME: SM-G930W8

I guess it's no wonder it didn't work!!!!! I'm just glad the flashing TWRP and LightROM for the wrong model didn't ruin my device.

Edit: Turns out that the hardware in these two models is the same, so no surprise it didn't cause trouble.
[Redmi Note 8 Questions & Answers] Meghazi:
Hi guys,

I don't know where post my question, so I apologize if I'm not in the right place.

I want to unlock the bootloader of my redmi note 8 to install twrp and install beta roms.

When i did use "mi unlock software" it say that i have to wait 168 hours to unlock the phone, any solutions to unlock it properly without waiting ??

Thanks in advance
[Redmi Note 8 Questions & Answers] loopypalm:
using mi unlock is the way, and waiting is mandatory

see the guides
[Redmi Note 8 Questions & Answers] Meghazi:
Thanks, I will wait until 168 hours elapse and redo the instructions.
[Redmi Note 8 Questions & Answers] MrGooseGoHonk:
does unlocking erase data now?
[Redmi Note 8 Questions & Answers] pnin:
Yes, unlocking the bootloader will make a factory reset on most devices.
[Redmi Note 8 Questions & Answers] MrGooseGoHonk:
when i use mi unlock, it didn't show warning about factory reset or erase all data. Does that mean it won't do that?
[Redmi Note 8 Questions & Answers] pnin:
No, it means a factory reset will be performed all the same.

[MTCD  Android Head Units Q&A] objecttothis:
Edit: TL;DR The wiring harness does not have Rear RCA outputs (only front and subwoofer). I had to splice in the RCA for the rear because there are pins outputting signal. (See solution below for details)

I'm running Hal9K Mod with Android 10 flashed. I bought this head unit a couple of years ago from iDoing on Aliexpress and I'm just installing a 4 channel amp for the front/rear door speakers and a monoblock amp for the rear sub. The sub RCA (brown) is sending signals fine and the FL Out/FR Out is sending signals fine, but the adapter dongle they sent with the head unit doesn't have RL Out and RR Out, like I would expect. Instead they have R IN and L IN! WTF? I contacted the seller and they were fairly useless. I plugged in my rear RCA pair into those but get no signal from them to the amp. Just to make sure that it wasn't the speakers or the amplifier, I switched the front and the rear RCA cables at the amp and then it sends signal, so I know the RCA cable is good, the amp is fine (at least on the front signals) and the speaker is fine.

Is there a software setting or another dongle that I can purchase that actually has the proper RCA outputs? I was expecting to unplug one dongle and plug this one in and then it would only send speaker signal to the RCAs but instead its still sending audio through the plain wires (I've only done one rear speaker so far). Anyone have this head unit and 2 Front, 2 Rear and one sub output?

Edit: The pinout on the MTCD and MTCE are different. This pinout won't help anyone with an MTCE. See solution below.

[MTCD  Android Head Units Q&A] objecttothis:
Here's the PX5 datasheet, but I didn't see any wiring pinouts in it.
[MTCD  Android Head Units Q&A] objecttothis:
I have a multimeter and I could test the pins if I know what to look for. I could likely isolate the signal by setting the fader to the left rear and then test each of the pins while music is playing, but I don't know what reading I'm looking for to tell me that I found the correct pin. Then once I find the correct pin, I'll need to figure out how to pull the RCA plug from the useless pin in the harness and insert it into the correct one.
[MTCD  Android Head Units Q&A] objecttothis:
I figured it out. I went to a local car audio electrician and we probed it together. I'm posting the solution here for anyone else with this head unit that wants to use Rear Audio RCA. The R IN and L IN

are not

outputs for the rear L and R speakers like the seller told me.

We had to cannibalize an RCA pair from another wiring harness (although you could repurpose R IN and L IN if you wanted). Here are the pinouts that you need:

- Left Rear RCA signal (white): 4th pin from the right on the bottom row.

- Right Rear RCA signal (red): 4th pin from the right on the top row.

- Shared negative (black): 7th pin from the right on the bottom row.

It works perfectly now. I hope this is helpful for anyone else.

Good result. Thanks for posting.
[MTCD  Android Head Units Q&A] marchnz:
Send it back/warranty
[MTCD  Android Head Units Q&A] objecttothis:
Agreed. If the wiring is setup like I have pictures and you still get no signal to any of the RCAs then it may have a defect or they didn't include some hardware.
[MTCD  Android Head Units Q&A] objecttothis:
Alternately you could purchase a line level converter and use the factory speaker wiring to create your signal for amps. Some amps even have this built in. My Rockford fosgate does.
[MTCD  Android Head Units Q&A] Bob_Sanders:
The problem with that is there is no sub output. You would have to create your own.
[MTCD  Android Head Units Q&A] objecttothis:
Yeah, I misread @kukoladam s post. I thought he was getting sub output. Maybe a DSP then... But that's starting to get expensive. I'd send it back or start testing pins on the back of the unit. The way the car tech did this that I took it to is that he had a single wired headphone connected to a few probes. He switched the head unit on and turned on radio static with a reasonable volume then started probing using a known ground pin to see which pins were giving him output. Turns out my rear channels were on pins that the harness had no RCAs wired to.

There may be more eloquent ways to detect signal with a multimeter that someone with more experience than I could explain. In an ideal situation you would do this testing in a bench environment, but in a pinch you can do it on your car as long as your wiring allows you to pull the head unit out enough to probe the back.
[MTCD  Android Head Units Q&A] lvdabeach:
Im a noob here. Sorry in advance for the dumb questions.

I have a similar issue but my RCA-RR and RCA-RL are on the 4 pin adapter. Which of course did not come with the radio.

Does anyone know where i can find this plug? Or even what these types of plugs are called?

From the attached pic you can see they are located in output socket C.

For the lifge of me i cant find a plug forthis socket.

I have an AT&T tilt and I just upgraded it to the WM6.1 ROM from the HTC webpage and since then I have noticed that when I turn of the screen, all of a sudden it just lights up for a sec and turns off again, without any reason, is there a way to fix this, do i have to flash it again? what do I have to do?

My Tilt does the same thing. It's a whiteish-gay light. It'll come on for short bursts or I'll notice it on in the middle of the night, and who knows how long it's on until I notice it.

I had upgraded to WM6.1 a while back, and didn't have any issues, but had to hard reset my Tilt and it has been doing it since.

It doesn't do it all the time, either. Weird.

[Tilt, TyTN II, MDA Vario III General] HBEAR:
I seem to remember there being an issue with screen flicker when the Tilt first came out, I think it was related to having Telnav selected in the today screen items tab. Try removing the checks one item at a time from the items tab, I doubt it will be as simple as a software conflict but it could be worth trying.

I had an issue with SPB Pocket Plus on my today screen, once I moved it in to a tab on SPB Shell the issue disappeared.

I am glad that I have found other people with the same issue as me. I thought it was just my phone, as I do a lot of backups and restores after I do something stupid with my phone and I also use a lot of beta/unstable software, and figured it was caused by these. However, it only happened after I upgraded to 6.1 stock ROM. Maybe somebody can figure out exactly why this happens, and then we can come up with a fix.

[Tilt, TyTN II, MDA Vario III General] zyxtia:
Possible Solution

If you are still under warranty, call up AT&T warranty replacement (Customer service is 1-800-331-0500, and just ask for warranty department), and tell them you have this problem. TELL THEM YOU THINK IT IS A HARDWARE ISSUE, and they will send you a replacement, refurbished Tilt. The next one will also have WM6.1 on it, and do the same thing. HOWEVER, it is AT&T policy that after two replacements, instead of getting another one the third time, they give you a refurb of a DIFFERENT MODEL. That is how i got the AT&T FUZE (a.k.a. the HTC Touch Pro, a.k.a the "Raphael"). It doesn't have that problem. But otherwise, i have no other suggestions. i'm just sick of having AT&T screw up the phone's software, and then try to pass it off as quality.

[Tilt, TyTN II, MDA Vario III General] Kodok:
I always thought it's a hardware issue until I saw the hotfix just yesterday and applied it. The hotfix somehow didn't fix the intended issue but somehow greatly reduced the number of the flickering. What I found was I set the backlight into 2 mins when it's on the battery. When the phone flickered, it reset the backlight timeout to 10 sec. Since it didn't really fix the issue, I left it there for 10sec and I didn't get any flickers anymore.

I'll keep an eye on it to give an update.
[Tilt, TyTN II, MDA Vario III General] peterson65:

Power button issue

Dear all,

This is no hardware problem, but a microsoft WM6.1 feature, which is made to avoid the screen unintentional turning on (while in your pocket ofr example). However it seems not to be working the right way.

Some chefs do disable it when they cook their ROM, however it's enabled in the dutty ROM and in many others.

You can find some patch on aruppenthal thread post #195 http://xdaforums.com/showthread.php?p=2864939&highlight=backlight#post2864939

however it seems that it doesn't really fix the problem but just reduce the frequency it appears.

If you try it, give some feedback about how it fixes the problem for you.
[Tilt, TyTN II, MDA Vario III General] jadedea:
i think i found a fix

Ok I hope this helps for you because it seems to work for me. I first went to start/settings/sounds & notifications. Then I clicked on the notification tab and unchecked everything leaving only the ringer on for when calls come in. when I did that, for about 5 minutes (longest I tested it at) the phone did not turn on and the backlight didn’t do that weird grayish flash thing. Afterwords I at first was going to go down the list of all notifications and turn things on/off to see what wakes up my phone but i got too lazy and only checked one setting. One thing I noticed is that when I have the beam: autorecieved notification turned on for display a message on the screen I get that weird backlight flickering thing. So for now I just have sound alerts on when I receive any type of messages and a sound alert for reminders. So far so good, my phone hasn’t woken from sleep in 20 minutes.
[Tilt, TyTN II, MDA Vario III General] gpend:
quick and dirty fix for those that need sanity or at least battery life back.

This may be either a fluke on my tilt or it may just make the problem seem to disappear, but turning the backlight all the way down seems to be a quick way to reclaim battery life. with the backlight down on mine the stuttering when powering on also goes away. this may also be a hint to what is happening. Feedback is welcome.
[General Questions and Answers] Labsy:
Hi,

I am not sure whether is this Andorid-related, Samsung modem HW related, or even my ISP host related. Well, let me describe and then move on.

I notice when I am abroad, roaming, that when I go into low signal area and ROAMING (foreign operator) signal is lost, then my phone does not recover back ONLINE when I get back to area with excellent signal. In such situations my phone number will be unavailable even for whole day, if I do not notice. Very annoying, because I need to constantly pull out my glasses to see that tiny signal icon, check signal, whether I ma online or not, and if not, reset. Or use workaround instead of reset, to turn airplane mode ON then back OFF to reset signal, and voila, I am accessible again for calls and messaging.

What I tired already:

first, I checked with my wife, she has LG G7 smartphone AND she is subscribed with another ISP, and she does NOT have any similar problems. we are traveling together to those areas without signal and back to civilization.

then I sent my Samsung Galaxy S10 to service, and of course, they did not find any problems

then I changed my SIM card for new one, but no difference

then I got angry and bought new Samsung S21 Ultra...but first trip abroad, roaming + to areas without singal, same issue again, only me, my wife no problems

So... any idea?

Is it Samsung, my ISP operator (like, maybe they have some weird roaming algos?), or Andorid 10 and 11 bug?

Hello peopl

A few days ago they gave me one of these tablets, they did not want it because it is already a few years old and its software must be discontinued.

I know little about these issues and I thought I would take advantage of the fact that it is not a latest model tablet and I can learn more easily (since I don't lose much).

I've been seeing that the G100 can be brought up to android 4 using the ROM of the Acer Iconia A500 but I don't know if it is possible with the G100W.

1) Factory reset (no root, google account or external applications)

2) Has problems connecting google account

3) The browser has a problem opening certain pages (it mentions that a secure connection could not be established)

4) About the tablet:

Android version: 3.0.1

Kernel version: 2.6.36.3-00001-g36afae5

Build number: PB_G100W_1.007.03_COM_GEN1
