[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] rhricik447:
Bubble-burst here...

First and foremost... you can't get Android 10 on the SMP-900. This is an older device and is no longer supported/updated by Samsung, so the binary blobs that connect the hardware to the operating system are stuck at Android 5.0.2 (I think - the numbers AFTER the decimal may be off by a few, but point is that Samsung's last supported update was for Android 5.xxx). There are some later ROMs (what you're trying to load) that were made by some great developers that shimmed those binary blobs into a newer version of Android (AOSP) or LineageOS that makes the tablet quite usable and enjoyable.

I personally am running LineageOS and OpenGapps (the OpenGapps project is an open source version of Google's proprietary framework that makes things like Gmail, Calendar, Play Store, etc, work) and it works great. That at least gets you a more up-to-date tablet that runs better than Samsung's last update.

It sounds like you got a corrupted op/sys or bootloader and a corrupted (or missing) recovery image. The reference to Odin is the mode it is currently sitting in - Odin is the software that Samsung uses to load the images onto the device. You are basically holding a 'raw' SMP-900.

You are going to need to:

1) Download a copy of Odin for whatever operating system you use, i.e., Windows/Mac/Linux

2) Download a copy of an official Samsung Android 5.xx ROM (to get the new bootloader you'll need to upgrade to LineageOS later - trust me, you want this!)

3) Use Odin to load the official Samsung ROM on the device

4) Once you have the device booting up on the official Samsung ROM, you're back in business

5) Download TWRP recovery for this device (v1awifi) and use Odin to install it

6) Root the tablet

7) Install LineageOS

8) Install OpenGapps

9) Install the LineageOS root app (or install Magisk... your choice)

10) finish up the installation with whatever software you want to install from Play Store

Since most, if not all, of this is well documented in various places on this site... the search box can be your best friend. Most everyone here will offer help if you run into trouble, but please search this site first - there are some really, really good instructions and videos of just about everything you will need to do to get the SMP-900 to an nice, usable tablet. Oh, and remember that this is a 32-bit device, so when you go to OpenGapps, make sure you select the 32 bit version.

Good Luck, and remember to read/watch stuff twice, THEN do it.
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Vasubandu:
Thank you so much, friend. This is exactly what I was looking for. I am quite capable of searching and I have been a lifelong of measure twice, cut once.

I have downloaded Odin for Windows, and it recognizes the SMP-900, so that is something. I really appreciate the heads up about Android 10. I wondered about it. Double thanks for the 32 bit warning. I downloaded the 64 bit.

You have given me a clear road map, and I no longer feel lost. I completely understand about searching before asking questions and will try to make any questions I ask focused. People here have been very generous with their time in the past, and as you said there is a lot of wisdom for the asking here.

I think I will track my progress and perhaps put up a post detailing my experience for comic relief if nothing else.

Your reference to Lineage is new to me, but if I understand you, it will serve my purposes.

I will upgrade the SMP-900 to the latest Samsung ROM as you indicated. That makes sense, and I tried earlier, but it would not install.

Again, I cannot thank you enough.
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Vasubandu:
You da bomb!

Thanks again for your help. I am not at Android 5.0.2 and ready to move on with TWRP, boot and lineage. You have made a terrifying process understandable.
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Vasubandu:
Mission Accomplished I think

I followed your instructions carefully and had to do some research along the way. I did not find an official lineageos file for the P900, but did find files here for 14.1 and 17.1. I ended up installing TWRP from Google Play, and once I figured out how to start it, things seemed to go well. Took a while for me to understand not to unzip the zip file. I downloaded

lineage-17.1-20200412-UNOFFICIAL-viennalte

lineage-14.1-20200523-UNOFFICIAL-v1awifi

open_gapps-arm-10.0-stock-20200523

open_gapps-arm-7.1-pico-20200523

to my SD Card. Then, in TWRP, I wiped everything and tried to install lineage-17.1-20200412-UNOFFICIAL-viennalte and open_gapps-arm-10.0-stock-20200523. That did not work. I got some kinds of error or reset message. I wondered if 17.1 was pushing things, so I tried again with lineage-14.1-20200523-UNOFFICIAL-v1awifi and open_gapps-arm-7.1-pico-20200523. That time, it went very smoothly. The device now boots up with LineageOS. It seems to have Android 7.1.2.

My purpose for the table was to watch Hulu, Netflix, Amazon Prime video and Youtube basically. Maybe play games if I ever have the desire. Nothing would loan on 4.4.2. This time, I was able to install everything from Google Play except for Netflix. I kept getting a message that my device was not compatible, but a little searching took me to a Netflix page with a direct download, and now everything seems to working great.

I cannot think of any Android advances after 7.1.2 that I really want or need. It seems to suit my purposes as is, so unless I discover a reason to throw caution to the wind, I think I will leave it as-is.

You took a task that seemed impossible and gave me the guidance I needed to figure it out. I am sure that you saved me at least 20 hours of searching that may not even have been successful. It is so wonderful to encounter people like you who will take a few minutes to help people you don't know. I will always be grateful, and I will think of you every time I start the device. Thank you.

I'm wondering if I could get a small tablet with, say, a 7-inch screen, that I could mount on my dash and will automatically connect, via Bluetooth, to my android phone and give me support for Android Auto, Google Maps, GPS and such? Is there such a thing?
[Android Auto General] DJRepresent:
I guess what I'm asking is if there's a way to automatically tether my phone's internet connection to another tablet automatically. That would be ideal.
[Android Auto General] jrobbom5:
Yes. Check out Headunit Reloaded, it will do pretty much exactly what you want, except you won't be able to use Bluetooth (bluetooth can't handle AA), so you will need to use WiFi instead. You would set up either your phone or the tablet as a WiFi hotspot. It's available on the play store, and there is plenty of help available on the forum. Good Luck!

Hi everyone.

I have installed an Android head unit into my Mondeo but it didnt come with a DAB app. The ones I've found all seem to use DAB USB adaptors etc but I want to use the car DAB antenna that is connected to the head unit.

Can anyone help and point me in the right direction to download one?

Many thanks.

[Android Head-Units] junk68:
Don't know if you solved the issue by now, but as far as I know android radios don't have a built in DAB receiver. You have to purchase an external USB Dab dongle. Afterwards you can try with DAB-Z app

[Samsung Galaxy S9  Questions & Answers] Stormer99:
I have a new Sprint unlocked Samsung S9 SM-G960U1 and am trying to get the wifi-calling to work with Cricket Wireless. Currently the wifi calling option doesn't even show up. I was wondering if flashing an after market ROM would enable me to access the wifi-calling feature. Cricket supports wifi-calling, but only on Android devices purchased from Cricket (a note I didn't see before I bought the phone). If there is please letr me know which ROM would help me achieve this.

Thanks
[Samsung Galaxy S9  Questions & Answers] TheMadScientist:
Wifi calling and volte do not work on byod there is no roms for this phone. You can root but I can assure you this isnt gonna work either. All you can do is buy a cricket wifi calling enabled device
[Samsung Galaxy S9  Questions & Answers] Youdoofus:
incorrect. it merely needs to be provisioned by cricket on the back end by someone who isnt the typical moron with a headset. the reason byod devices have trouble is due to the IMEI not being listed in their system and it takes a ticket to be sent to the telephony dept and have it added. They dont like doing it, but they will when pushed. Unlocked A8 and A6 on cricket both had wifi calling and VoLTE after provisioning was complete.

you also have to have the right csc on the phone.
[Samsung Galaxy S9  Questions & Answers] TheMadScientist:
I have a method with imei from a good cricket wifi calling phone. And have it working. But I have to give them another imei once I have it provisioned. Once their system updates with my imei I lose my wifi calling. But after provisioning I give them my actual cricket devices imei and tell them the system is still showing my byod imei they need to change it back to the other device. It works. But imei in their system is wrong.

Not imei switching or anything like that. I physically own a stylo 5 from cricket I dont use. So they think I'm on that and not my g9650. So I know it's possible just a real pain

[Google Pixel 3a Questions & Answers] 100rabh7791:
Hi guys

I am looking to buy a phone for my gf. she doesn't want a screen bigger than 5.5inch. She is currently an Iphone user but i want her to use Pixel.

I am however, a bit confused between these two models. I wanted to know your day to day experience regarding the phone? does the 3a lags? or how has it held up in performance till now?

Her usage will mostly be light to moderate. It will mainly consist of some normal games (not too heavy), Web browsing, video calling and streaming. Can any1 please share their experience with this phone and anything i need to be worried about?
[Google Pixel 3a Questions & Answers] Skittles9823:
Personally I'd suggest waiting for the 4a to be released.

The pixel 3 has battery drain issues and the 3a series is great, but with the 4a right around the corner it makes far more sense to wait for that.
[Google Pixel 3a Questions & Answers] mike.s:
3a has an audio jack and better battery life. Currently on sale, too.
[Google Pixel 3a Questions & Answers] gman88667733:
The 3a doesn't 'lag'. It isn't as quick as say a OnePlus 8 or similar, but it is most definitely not slow.

Coming from OnePlus phones and iPhones, I don't notice a crazy difference really, it never feels slow to me.

There are some micro stutters on heavier animations or processes, but on the whole it is smooth and quick.

I would buy it again given the sale price and how much I like mine.
[Google Pixel 3a Questions & Answers] 100rabh7791:
Thanks Google is just delaying the 4a which makes me so sad!

One more question what do you feel about the ram management? Is 4gb enough?
[Google Pixel 3a Questions & Answers] 100rabh7791:
Hi thanks for your response! Can you tell me now about your day to day usage? And also regarding ram management?
[Google Pixel 3a Questions & Answers] gman88667733:
I tend to close out apps when I'm done, so I rarely ever notice ram issues on any phone I use.

If I open up 10 random apps, it holds them all as far as I can tell. You'll probably see issues if you're opening up lots of games, but not normal apps.

Day to day usage is perfect honestly, I would choose the 3a over the Pixel 4, the new OnePlus phones or any Samsung. For me it just works. I never have to charge it during the day, the camera is amazing, the screen is good, it is perfectly fast for me and the speakers are decent.

Plus, I get better cell reception on this than any other phone I've ever had
[Google Pixel 3a Questions & Answers] Skittles9823:
4gb is more than enough. The way ram management works on Android pretty much means any device which has over 4-6gb of ram is just wasting ram as free ram is useless.

---------- Post added at 04:09 PM ---------- Previous post was at 04:07 PM ----------

Just a heads up, that's not great for battery life. Opening apps uses more CPU compared to leaving them in memory, and android will automatically kill the most resource intense background apps whenever it needs more.
