[Android Head-Units] Olli.D:
Hi Android Auto likers.

i'am new to this, so i need a little help please.

I have a head unit in my car now and some things i miss. So i come here!

For my understanding:

The deep operating system is the ROM, like Bios on a PC?

The MCU, in my case MTCE_CZ_V3.06_2, is the connecting part, or translater between ROM and Android? Like DOS in earlier times.

Android now is like Windows.

My android version is 9.

- The sound over Line out has a background noise

- settings are missed, compared to the smartphone

- instable some times

What i understand, first flash the latest MCU, is that right?

In my case a MTCE_CZ only (found here: MTCE-CZ-3.30sp+by+cs-x)

What means sp+by+cs-x?

I would be happy, if you make some light inside of my head ;)

Regards, Olli
[Android Head-Units] nic2k:
You will see many abbreviations through the forum as you've noticed. You are a bit confused though. First what things are:

- HU: Head Unit, the radio.

- SoM: System on Module, that's basically the motherboard you would find inside an Android tablet.

- SoC: System on Chip, that would be the CPU + GPU+ IO. That part is on the SoM.

- MCU: Micro Controller Unit, is an interface between the car and the SoM and also gives the SoM WiFi connectivity, USB ports and Bluetooth capabilities.

- ROM: The chip that contains the operating system and is also used to describe the firmware.

So you have 2 systems talking to each other and each has it's own firmware. There are custom Android firmware for some SoC's but all can used the generic Android as long as you match the ROM partition. The MCU firmware you have (MTCE_CZ_V3.06_2) is specific for that MCU, vendor and resolution. You must match all the characters except the Version number but you knew that. MTCE is the MCU type, CZ is the vendor and 2 is the settings preset and is usually related to the display res. You should only upgrade these HU to solve a problem. Before you upgrade the MCU always export the settings from the factory settings menu, in fact you should probably make a backup for safe keeping anyway.

In the MTCE-CZ-3.30sp+by+cs-x filename the "sp+by+cs-x" stands for sound patched by cs-x. There's an issue with the audio level and cs-x found a solution, read the thread.

The background noise from the line outs whether you're talking speaker outs or RCA's is due to the low quality of these HU but could also be caused by the gain setting in the factory menu. Some people have found solutions for that are specific to the cause/type of the noise. You'll have to search. Same goes for the instability. Look at installing a heatsink or removing some apps.

These HU's are not phones so it's normal Android settings are missing.
[Android Head-Units] Olli.D:
Thank you very mouch, that you take the time, to explain this to me!

I'am sure, many others will read with lot of interest.

Yes, the reason of background noise (here RCA), is quality. But you get a mega system for very small money...

I have a seperate DSP (Mosconi) with digital input and would love to use it.

Some weekend, i like to have a view inside of the machine, if there is a digital output.

The only mistake of the system now is, original FM/AM Radio failed. No sound, and starts not on last station. Reset here, and adjustments there, it works again.

For 1-2 days... but didn't find, what cures. One time on poweramp, there was TA, Traffic Information, Radio worked again for a time.

Best regards,

Olli
[Nexus 7 (2013) Q&A] ahmed123:
I have a 2013 nexus 7 with the last edition of the Timur's Kernel before he stopped supporting it any further. I've put a powerdown.mp4 and powerful.mp4 video clips in the root of the device. When I cut the power to the charging port the video plays and so does that startup video. However, I can't seem to find any way to remove the information text that displays on startup showing how long it was sleeping for and how much charge lost etc. Same with the sleeping it shows some text and a countdown and I really want to remove this as it spoils my powerup and powerdown animations.

Does anyone have any experience with this?
[Android Q&A, Help & Troubleshooting] joshjonasone:
I can already guess the answer, but I still have to ask to be certain.

I have an A7 (2016) and I really need to port Android 9.0 Pie to it. I need a proper mostly stock rom. (basically a manufacturer rom) I haven't been able to find a phone that uses the same chipset (I doubt it exists)

Below two phones do not have the same chipset, but I am hoping they are similar enough for it to work:

https://www.phonemore.com/specs/samsung/galaxy-a7-2016/sm-a710f/

https://www.phonemore.com/specs/samsung/galaxy-j7-core/sm-j701fds/

My question is, would it be possible to port from a different chipset if they are similar enough? Is there a way?

Thank you all.

[Samsung Galaxy Fold Questions & Answers] super_Ken:
Just bought the Samsung Fold SM-F900F in India. Surprising, Samsung's India website states the phone supports both Nano SIM and eSIM. However, my phone has a grayed out eSIM IMEI on the about page under settings. I know with surety that it is not carrier locked. So my question is, if I flash my phone with a firmware from Sammobile for a different region such as France, Spain, Singapore, etc. Would it unlock the eSIM on my phone? Samsung's website says the following Countries and carriers support eSIM:

Australia: Optus, Telstra, Vodafone

Finland: Telia

France: Orange

Singapore: M1

Spain: Movistar, Orange

Thailand: AIS

I am assuming a firmware from any of these countries should also have an active eSIM profile.

At the moment, it doesn't even have the activate mobile plan and other menu options required to add eSIM profile under settings.

Also, its been a while since I played around with android phones. Are the firmwares provided on SAMMOBILE stock versions?

Thank you. Felt amazing to write my first post/reply.
[Samsung Galaxy Fold Questions & Answers] anvesh3773:
Hi, I also have the 900F the Indian unit with the esim option greyed out. I am assuming the same way you do if we flash an international F firmware we might get the esim functionality back. My local samsung dealer imported a phone from uae and the esim version is working in India on that unit. So an educated guess would be flashing that firmware and checking..

[Samsung Galaxy Fold Questions & Answers] vietamins:
In the USA... my fold was initially greyed as well. After researching, I was able to contact AT&T whom said that the do support esim and could enable it. Would just need to talk to the instore sales rep and they should be able to provide you with a scanable q card.. once scanned, feature is enabled and sim slot is now freed up to use with another carrier. Not sure how other carrier works in other country

[Samsung Galaxy Tab A series Questions & Answers] dmathis:
Does anybody know what kind of schedule Samsung follows for their tablet updates? I just received an SM-T290, and it's on Pie (T290XXU1ASH1/T290OXM1ASH1), but with the June 1, 2019 security patch. My galaxy note 8, however is on the October 1, 2019 security patch.

Is there anywhere to download the newer security patches? I'd think that Samsung would be quicker with their own branded stuff, especially in the case of tablets, where there's no need to pass the updates through the cell carriers.

Thanks for your help,

Dow
[OnePlus 7 Pro Questions & Answers] user822:
Hi,

I have a rather odd problem:

My phone simply does not boot when Magisk is installed

Installed Magisk 20.0 on Stock 10.0.1-GM21BA a while ago and everything was fine.

Today it won't boot any more (stuck on the warning that my bootloader is unlocked, then bounces to fastboot)

As soon as I uninstall Magisk from TWRP it boots again

Then I Install Magisk 20.1 from TWRP, it does not boot.

Then I uninstall Magisk 20.1 from TWRP, it boots again

Then I flash the pre-patched boot image from here and it does not boot again

Then I flash the stock boot image from here and it boots again

I also tried installing Magisk without dm-verity (only forceencrypt), still not booting beyond unlock warning and fastboot

Does someone know what is going on with my phone :confused:

Can I root it without Magisk?

Thank you for any help

Try TWRP 70
[OnePlus 7 Pro Questions & Answers] santiagoruel13:
Maybe you're on twrp v71... Try reverting to the older v70
[OnePlus 7 Pro Questions & Answers] djhulk2:
had same problem.i reflashed stock and locked bootloader back to offical, andriod 10 lets twrp work but not masgik. i even used magisk manager to patch file and flashed that file to have no more root
[OnePlus 7 Pro Questions & Answers] user822:
Thanks for the ideas, did not fix it unfortunately

Guess I will stay without Magisk for now :(
[OnePlus 7 Pro Questions & Answers] aNGERY:
do you have any modules hanging out?

https://xdaforums.com/apps/magisk/module-tool-magisk-manager-recovery-mode-t3693165

you could try that.
[OnePlus 7 Pro Questions & Answers] santiagoruel13:
Hmm.

Try this with twrp v70

1. Boot to twrp

2. Flash the full a10.0.1 rom

3. Flash twrp v70

4. Reboot to twrp

5. Flash magisk v20.

Reboot

Thats what i do if something is wrong.. i always reflash a rom..

---------- Post added at 07:22 AM ---------- Previous post was at 07:19 AM ----------

Re flashing a rom also saved my friend's phone..after flashing boot.img for rooting purposes..he always boot without a wifi. So we dirty flash a rom.first . Then using that same rom that we flashed.. we extrscted its boot.img then patched it with magisk. Then re flashed.. then boom.. its working now..

Reflashing the full a10.0.1 rom.solved the issue..

---------- Post added at 07:24 AM ---------- Previous post was at 07:22 AM ----------

My idea here is that

Flash the rom..

Then using the rom that you just flashed..

Get its boot.img.. then patch it then flash it again.. it will now boot. I havent tried directly flashing a patched boot.img without reflashing the rom first..
[OnePlus 7 Pro Questions & Answers] coolguy001:
I met the same problem this morning. Did the following thing to let phone boot with magisk.

1. install magisk 74

2. install Magisk-uninstaller-20200110.zip

3. reboot magisk

4. install magisk-v20.3.zip

5. boot system
[OnePlus 7 Pro Questions & Answers] tolol:
do you mean in step 1, Magisk Manager v7.4.0
[OnePlus 7 Pro Questions & Answers] tuff3r:
Did anyone figure out how to fix this issue? I have tmobile and after updating to 9.5.5 and installing magisk it works until I reboot again and then it hangs and goes to fastboot. I try to narrow down the problem and it happens after I install adaway maybe after I choose system less. Or after installing YouTubevanced. Idk what I'm doing
[OnePlus 7 Pro Questions & Answers] Bxperiaz3:
Did anyone find a fix to this ? I'm having the exact same issue.

Flashing magisk 20.4 gives a bootloop. Uninstalling via TWRP allows me to boot to system. No overlays no modules etc,everything uninstalled but still cant boot with magisk. Have I missed something? The only solution I can find is factory reset and begin again, which I can do but as a last resort.

Just wondering if the spring loaded holster fit with the extended battery?
[Mogul, XV6800 Accessories] rleejr79:
I think I read on the actual site that it does. I velieve I was reading the ext. battery product info. I have the Seido black rubberized case and the spring holster and was thinking of upgrading as well.

Hopefully, themirthfulswami will inform us soon.
[Mogul, XV6800 Accessories] LvsSocer:
I second that experience - best change I've made to my mogul.

Before using the battery, it was a race to see if the battery died before the end of the day. Now I can miss a night or even two of charging and it doesn't even matter.

A word of warning: The mogul is already decently large. Adding the extended battery pushes it to the edge of being useful in one handed operation. Not that it isn't, you just have to learn to hold it slightly differently.
[Mogul, XV6800 Accessories] Duke Nukem:
Hello

I have tried few 3000mAh batteries and they perform great. i get to use my Titan for 4 days without charging... If anyone is interested I can get them for you for 35$ with back door included...
[Mogul, XV6800 Accessories] nas917:
Who do I need to send the money to get the extended battery?
[Mogul, XV6800 Accessories] JokeZony0u:
So I noticed the original person never got back to completing the review. So here's my two cents:

I'm generally a heavy phone user, especially with texts, emails and web surfing due to job reqs. Here's my typical settings:

WiFi- off

Bluetooth- off (on roughly 1 or 2 hrs max a day)

Brightness- 100%

Email: 2 accounts, 1 checking every 5 minutes (Yea, I actually need it) and the other receiving emails as they arrive (meaning I get them immediately upon receiving)

Auto off: 1 minute

Data Connection: On at all times

Software Running: Just switched to Manilla 2D- definitely a cool program to check out, SPB Pocket Plus (no today plugin)- using it to flick through IE

Texting: I don't know how many I text/day but I've hit 3000 in a month

Talk times: light to moderate

So I've never actually drained the extended battery to nothing, since I'm still used to charging it on a daily basis. I generally start my day off at 6 in the morning, its now 2:00 at night and the meter shows 50%. So typically speaking this thing beats the original battery by a lot. I won't charge tonight and see how well the battery does tomorrow. Along with the battery, I also got the extended battery case which fits snuggly and also covers that "middle lift up" the original person had a problem with (I guess its a problem with all the battery doors). I also have the spring holster- which fits both regular and extended battery phones.

As for how well the battery will stand up to my rigorous usage- I'll update you all once I'm through with tomorrow
[Mogul, XV6800 Accessories] Paul in Maryland:
big batteries need a fast charger

I put my 3600mAh Mugen in the charger at 10pm and remove it at 6am. If I try to it with the standard XV6800 charger (250mAh/hour), it won't charge all the way. Instead I use the 450mAh charger that I bought on eBay to charge the Mugen outside of the phone. Except I don't remove the battery from the phone; the 450mAh charger uses a standard USB cable, so I simply plug the cable directly into the phone.
[Mogul, XV6800 Accessories] JokeZony0u:
As to that, I haven't had any problem charging the battery up to full using a regular charger. I generally plug it in probably 12 or 1 pm and unplug it at 6 or so. Then again, I never fully drain my battery.

As to the "review" that I had going yesterday, I am currently at 20% after 38 hours of use. I'm guessing this 20% will last several hours more since it was on 30% for several hours before
[Mogul, XV6800 Accessories] TdiDave:
I just got one of these battery. When i plug into the charger the charging lite just blinks. Left it like this over night and still blinking.

Does this on 3 chargers:

1 - 5.5 V @ 1.0 A

2 - 5.4 V @ 2400 mA

3 - 5 V @ 850 mA

Any help ?
[Mogul, XV6800 Accessories] JokeZony0u:
Are you using a seidio battery?
[Mogul, XV6800 Accessories] TdiDave:
Yes the Seidio 3500mAh battery is the one that wont charge. My stock battery charges fine.
[Mogul, XV6800 Accessories] JokeZony0u:
Hm..are you using the charger that came with your device? If that doesn't work..its most probably due to the battery. Seidio has a warranty on the batteries they sell

Email them first and ask what you should do, you most probably will have to ship it back if anything
[Mogul, XV6800 Accessories] TdiDave:
Leaving the battery out of the phone for a minute or so when changing has seemed to fixed my problem of charging the 3500mAh Seidio battery.
[Mogul, XV6800 Accessories] JokeZony0u:
Glad to hear it! Enjoy the crazy long lasting battery life we've never had before with the stock ones!
[Mogul, XV6800 Accessories] meccanoble:
I actually bought this battery off of someone used for 3 months. Life is way better than my original battery. My original was real funny. If i'm doing nothing, it would last a few hours with extremely basic functions including screen off for majority of time. If I was to make a phone call, battery would die literally after 10-15 minutes of constant speakerphone talking, even from a full charge. Pissed me off, I use my phone for many things and sh*tty battery limited me heavily.

After installing this new battery, I am using my phone for everything again. Slingbox, navi, bluetooth music listening, web surfing and ofcourse phone calls.

I am able to keep my phone off of charge for up to 2 days with heavy use. I work out everyday or try to and I watch tv through slingbox on my phone with Jabra BT620 bluetooth head phones. Thats a lot of drainage. Yet phone still does well with 2 days of use and no charge needed. I have emails set to come in every 5 minutes as well.

Here is one major issue this battery has presented to my phone when I originally got it but doesnt happen all the time. The beauty of our phones is that they are real easy to open and close. Real smooth. But can close very fast. First few times I closed it, it slams so hard I guess that the battery gets knocked out of place. I have to remove the battery completely and put it back in to start my phone up again. Very annoying but tested a few times and it doesnt seem to happen all the time. It has happened to me maybe 3 times since I got battery (almost a week) but it happened maybe 2 times on the first day.

It depends on how hard you do it. As I was typing this, i tested it a few times. Opened and closed pretty hard like 4 times in a row with no issues. 5th time, I did it harder than I normally would and it happened again. Aside from this, very happy with battery.
[Mogul, XV6800 Accessories] JokeZony0u:
hm, never had that problem you had. But in general- lets agree, the battery is a lifesaver for any powerhouse user
[Mogul, XV6800 Accessories] kzibart:
Ok, so the battery is great, but what about Seidio's customer service? Here's what happened when I ordered the battery, along with a charger, hard case, and a few other accessories...

"Dear [my name here],

Please refuse the package for the carrier. The order arrived to your address belongs to another customer. Please contact customer service at 832-204-1118 for any questions.

Once we received the package, we will reship your order ASAP.

Regards,

Seidio Customer Service"

I paid for 2 day FedEx delivery, yet they want me to refuse delivery, and then they won't even send the right stuff out until they get the wrong stuff back? My wife needs the battery for an upcoming business trip. She can barely use her phone today because the current battery doesn't even last a single day anymore. Besides, I didn't get this e-mail until yesterday on the way home from work, and the package was on my front porch when I got home.

Of course, customer service was closed for the night, so I replied asking that my correct items be shipped out in an expedited fashion and offered to return the incorrect package however they wanted me to. I'll follow up today with customer service once they open as well. Wish me luck!
[Mogul, XV6800 Accessories] kzibart:
Here's an update to my Seidio shipping issue. Apparently someone else with my same first name placed an order at the same time, and somehow ours got switched. When I called this morning, the person I spoke with said the same thing as the e-mail, that I would have to return the package and then they would ship the right one once they received the wrong one.

Since we really needed the extended battery, I went ahead and placed a second identical order and chose next day shipping. Then I called them back to cancel the original, but to my surprise the person who answered knew of my situation immediately and we came to the following agreement. I would return the package I received, and at that point they would refund my original purchase price plus the cost of the next day shipping, meaning I am still paying 2nd day shipping for something that will have taken over a week to arrive. But hey, at least I'll finally have it, and my wife will be able to use the extended battery on her business trip.
