New life for a Tab3 (SM-T820) - Galaxy Tab 3 Q&A, Help & Troubleshooting

I got this tablet exactly 3 years ago, and at the time it was the fastest tablet around. Today it is slow as molasses. It's not that I have a lot of apps installed, in fact I mostly just use it to watch (Vanced) Youtube and some IPTV.
Is there any chance of getting life back into it? It's running Android version 9, which is the latest they support for this device. I don't really care about newer versions, I don't find a lot of exciting new stuff is coming to Android anymore, but sometimes it feels like they purposely make the tablet slower, perhaps to encourage the purchase of the latest model, when it really shouldn't be necessary.
(Actually it also have some really idiotic "features" like although it has a fingerprint reader it keeps insisting I have to enter my pin to login "for my safety". My safety my butt, I only use it in my house and in any case don't have anything secret on it. It just annoys the hell out of me when a piece of hardware tell me how to use it.)
So is there a solution to make it fast again? What? Reset it back to an earlier stock version, or install another rom? It has pen support, but it's not something I use a lot so while a nice-to-have it's not a need-to-have.

Tilt 2

I stumbled on to this site looking at phones on ebay. Great find. I see that some of the threads indicate that some end users have been able to replace the ROM and OS on there Tilt 2 WINMO phones with Android and other fixes to make this incredibly slow freezing phone a respectable Smart Phone. I have been a WINMO user for over eight years and have never owned a bigger slower piece since my original brick phone. Have had it replaced twice and now am going to switch to the new Android offering from At&t. But if I can make this better phone I am all about it. I know I sound like a total rook but some help would be appreciated.

sure you can replace WM with Android, but remember its not a fully operational OS because its a port, so i hope you can live with no sound, bluetooth and no camera....battery could be an issue but with the latest builds its been a HUGE improvement ever since the project started, and also to have a MicroSD card in hand to make Android work, but keep in mind the speeds are not going to be like Windows Mobile since it runs off of a MicroSD, but if you really up for it and you want to speed up your Tilt 2 if youre on WM, i recommend flashing a ROM just be sure to HARDSPL before you do

Cool so Android is out on the Tilt. I noticed what you have done with your tilt 2. Even though I am Computer savy I would like to do something somewhat easy for the first time out. Thanks for the help I will check out the info you gave me and hopefully get it done right.
I keep reading posts about what a POS the Tilt 2/TP2 is and I'm baffled because mine just doesn't seem to fit that description. Mind you, it's no speed demon, but it does all I ask of it with ease. And I've yet to have it freeze up requiring a physical reset. I hard reset it once, but that was because I installed some stuff that wasn't designed for it. I've modded the heck out of mine and gotten the eye candy (of which there's a ton to choose from) where I like it. Yesterday, I impressed some friends when I quickly got some restaurant info from Bing on my phone and then did a quick Skyfire search on some rock band to settle a bet. This is not my first WinMo device, but it certainly is the best so far.
brother I wish mine was all that. I got my first htc tilt2 in Jan this year. Did alot of research and did not find a whole lot to worry about. Got the phone and was happy for about the first month was up. The internet is slow, constantly freezes, when switching to keyboard the darn thing goes three ways from sunday and locks up. I have actually seen static like on my tv. So I went to the local At&T device support center and the dough head told me its windows you will have to learn to deal with it being a hunk of junk. On my second one signal sucks still slow as hell and locks up all the time. Have had to reset (hard) numerous times. Not gona get rid of them, however gona check out some of the mods and see how it goes. The HTC is also not my first WINMO originally started with the orginal Black Jack and dont look forward to the droid conversion. But Will check it out and Hopefully mod this one out with this site.

[Q] SM-P600 with 3G USB Key?

Hello,
I have a SM-P600 with Android 4.4.2 (Note 10.1 2014 Edition) and would like to use my 3G USB Key (Huawei E1752) ; This 3G stick works fine on my old TF101.
I've tried to use it with my SM-P600 but infortunetely, it doesn't seem to work, even with the "PPP Widget" apps. PPP Widget displays the famous "No driver found" issue. Josh, "PPP Widget" developer, told me ther eis no way for the moment to make his apps working because there is no loading module (.ko file).
So I wonder if I could use a SM-P601 ROM (SM-P600 with 3G) on my SM-P600 to get the right modules or flashinf P601 ROM on P600 means "brick"?
Otherwise is there another way to make a 3G USB key working on this tablet?
Best regards.
Unfortunately...
Part of the problem is that a custom kernel module would need to be loaded with root, via insmod, and this would need to be coded and constantly reinjected on boot. As far as I know most of these fobs do not make their drivers open-source, specifically, although I could see a possibility in modifying one of the generic drivers from a typical linux full install (likely heavily modified). Even with a ko/kernel module, however, it's possible that the fob might not be able to get enough power from the tablet, itself; I'm not sure what the power draw is, but I have a few laying around; I could probably check that later on.
All of that said, while it may be possible to try to hack something up to work with OTG (for instance I know it CAN be done with external network devices in general (there have been successful drivers built for external Alfa wifi usb-based adapters, but that's wifi), my suspicion is that even if 1) and 2) here were fulfilled, there'd need to be support in other ways built into the ROM itself (I'm wondering if a bunch of the code for this could be pulled from the existent 605 ROM though, which is a consideration). I'm not sure if, for instance, even if JB/KK on the Galaxy Note 2014 were to be made to recognize it, you wouldn't have to disable other things to make it work; I know for the external USB wifi devices, a hack was needed to disable the onboard wifi within the device.
If I had the time or the money I'd certainly be willing to try to make something custom in general. That said, I'm wondering if linuxonandroid (search the forums, or check out linuxonandroid.org) might support it out of the box on the full system img's (given functionality, Kali's kernel probably has the best chance of any of the current available ones, but I don't really know; I'm grabbing the image later on tonight to see what happens if I try)...
In general, though, I suspect that even if this somehow partially works, there are going to be a lot of problems that only a real custom ROM would solve. Though frankly, I can't figure out why nobody has yet. Maybe, like me, people just don't have enough time, and the people who do have time and the skill don't really need a specialized ROM enough.
I'm still kicking myself in the butt for not getting the 3G version for development purposes, personally; hundreds of dollars more for what one could get in a USB fob for 20-30 bucks only sounded like a bad deal til I wanted the functionality; your best bet may be to get a crapper of an android phone for under a hundred dollars and just let it be a hotspot. It's what I finally just gave in to doing. The one upside is decent battery life; if the P600 could supply enough power for the USB 3G dongle to work, all USB-dongled devices, to the best of my knowledge, kill batteries faster than anything built-in would.
Good luck.
Yes... You're probabably right. Don't know.
And I could use an old phone to be a hotspot or something else like that, but it's not what I want :cyclops: Just one device for all will be better.

I'd really prefer the same thing, myself. I generally carry around a phone with my other stuff anyway and don't use it for much in the way of voice calls, so it's not too much of a burden. There's also hostapd in linux, or any of a number of mobile routers you can boot up in vbox, if you're carrying a laptop around at the same time; I really hate that our devices, and android in general, won't do 'ad-hoc' networks. I think that's one of my biggest gripes.
I suspect once Ubuntu touch is fully stable it'll be our best option; at a minimum I'm pretty sure I could easily crank out a driver for that. Android, I'm not sure. I'll let you know if I find the time to dig around with with droid though; I've been meaning to learn more about device driver support in Android anyway, now that it's finally pretty much mature.

Do I have to give it up....

Good Day,
I have the the original HTC Incredible with Verizon. I am by no means a power user, big on downloading video or surfing the web on my phone (unless it is a semi-emergency). The problem is that some of the apps from my bank, local weather, AAA, etc. have been updating their apps. Some will not load at all and other I cannot use some of the new features of the new versions. Because I have the OS that is out of date.
I stopped in to a Verizon store an asked if I could get a OS update on my phone and of course they wanted to sell me a new phone. Said it was impossible to update the Incredible to a new OS. After a little reading on the forum, it may be so. But I am asking just the same, can my phone have the OS updated at least to a semi-new Android OS?
I like the size of the Incredible and every time they want to try and have me get a new phone I say "Sure, just get me one that is the same size as my Incredible or possibly smaller." That has stopped them all in there tracks. I do not want to carry around a tablet on my hip. And for a little as I use other applications I could almost go back to a flip phone, just kidding, well maybe.
Thank you for any suggestions or comments on my little situation. Have a great day.

So, the Droid incredible was my first android device, and sadly no. That thing is long past it's shelf life man. The fact that you're running on 3G only is a wonder and testament to you NOT using your phone. As you said, you really COULD go back to a flip phone. I can't imagine many apps still work on Gingerbread.
I'm sure if the device is rooted and s-off you can install some roms that were made for the device that take it as far as it can go. I just found mine in a drawer and my kid wants it for listening to music. I'm on hear just to see what Roms are out there if anyone is still using it.

Format after ADB errors and bloatware buildup?

Hey I'll try to keep this short but that never works for me these days so look for the TLDR tags below for the main point paragraph:
Got an 960W right before the S10 launched and I had done no reseearch before hand so I thought root would be easy I had an S4 for ages until it got stolen and then a Moto G lte which I loved when rooted but the screen stays all black pixles with backlight now and a lot kft he screen is broken off plus getting old the original damage I had a stroke and broke it during the fall that caused it so I used a loaner iPhone 5 till I bought the S9.
I Googled and read root guides and went awesome and bought it not knowing that root is harder these days on most devices and I picked the worst model to even try or wait for I guess. Back then m brain wasn't able to research and think things through much better than today just read a few reviews and put my cash down.
So lately it's been running like crap draining the battery very fast and such especially after pie was released. I had looked into removing bloatware and stock crap from the start once I learned it can't be rooted but the stuff never caused an issue or bugged me other than when bixby assistant seems to come up for no reason.
That is until recently: I've noticed terrible battery life particularly with Bluetooth and adaptive brightness on and when I started looking into it a lot of the Samsung apps and packages I never use are what's hogging a big chunk of availavle battery and CPU time.
So I finally figured out how to run ADB over WiFi and disable packages but of course I learned how to uninstall too. Disabled everything with one of the "here's all tbe stock apps you can disable" articles and I even deleted a couple that seemed weird like samsung.bixby.dummy and such but once I did that it ran amazing... however
The however ended though quickly; since I realized factory stuff I do use like Samsung health and cloud didn't wanna work. So next I tried to just reinstall Samsung cloud via an apk downloaded and that didn't really work so I just wrote a little bat file to enable everything disabled via adb bridge and stuff is hunky dory the couple packages I did totally use uninstall command on havnt caused any issues they just throw a Java error when trying to enable them via adb since they are uninstalled. Things are good other than my gripes and accumulated crap as well as tbe first issue that things just arnt snappy anymore+battery drain.
Even reenabled it's running nice and slick again but I do wanna clean stuff up I have 1150 apps with the stock factory and carrier junk so I figure it's time for a clean up.
I figure though maybe it's time to do a factory reset and install the LS5 or 6 build whatever we are on now on American and Canadian devices and go fresh then see what its like until I have time to swap with someone local for a brighter more open device.
I did read about how just a few weeks ago someone wrote up and was on Android news sites about TWRP working on the snap s9 for doing some basic things just the bootloader is still locked of course so I figure I might as well do a backup with everything reenabled via Samsung cloud, Google drive backup, and backup everything I can get read access to vis USB with all the dev options enabled.
Then I can do a full wipe and format/factory reset and from there I can disable any bloatware and Samsung stuff that I don't need. From there if everything seems fine then restore all my misc data and reinstall the other non daily used apps I want and hope Google saves all their data. The phone should be just like the good ol days when you had to do. A. Factory reset instead of upgrade when a good rom update came out and it ran great at first till you loaded it up with crap.
//TLDR
So would this be my best bet, backup via Samsung Cloud, Google, GCloud Backup and a full drive over USB and probably ADB backup save too followed by a wipe format and then install the latest update from Android 8 or whatever I end up with after factory reset. Restore/reinstall apps I actually use or need and their data where possible and then disable any stock stuff I don't use or need make sure everything is fine for a week and then run the adb uninstall command.
Oooor is there something I haven't been able to think of or find with my brain issues that would make it much easier to disable or delete stuff slowly package by package as well as just clearing the OS up? I remember week 1 I was like damn modern phone's are amazing... Going from a Moto surnia to the sltev930 or whatever the s9 code is made me say wow modern handheld devices are amazing but it's lost its magic since learning I can't root,of course, and the limitations associated with that even with Nova launcher prime and shortcutter;even with a ton of stock packages disabled or uninstalled I'm sure.
I just miss being able to do what I want and maybe it's just me or my screen protector but the screen on this thing is weak: I can't read it outside during the daytime wheresas the old worn out iPhone 5 with years and years on it is very easy to see anywhere even with sunglasses and even with jailbreak removed and the beta 11.4.1 on it not 12 yet that little apple loaner can hold it's own.
//End TLDR
//Bonus points: trying to use app2sd most apps won't move and even manually it goes to 90 percent or so and hangs for ages then finally quits and still says internal storage.
Is this a known Samsung issue or is it a problem with fat32 formatting or is my cheap 250gb SD card probably only a 32gb and rewriting over itself after a point?
Not only can I not put many apps and their data onto the SD card but it's become corrupted two or three times now this year and I have to backup everything on my PC and then format on Android and start again.
I dont know how much all data and general files and pictures on the microSD card ive lost now and ice stopped trying for anything with any importance. I haven't done a ton of research but dont know if there's a way to do a specific type of formatting to make it more compatible or some system flag thing I'm missing or maybe just because it's a cheap micSD card... I paid less for it at 250gb than I did for 32gb m.2 SSD for my 3d printer.
//End bonus round back to you Trebek.
I'm thinking about doing research properly and selling or trading the S9 for one of the new cheap Google phones or another Moto or whatever else I find that has good specs and display etc just like the S9 was to me at first. Im not sure what the resale value on a perfect S9 snap is but I'm sure I can get something with a nice bright readable display decent battery and some of the trimmings like inductions charging as well as able to root and install lineage or whatever once I do the research.
I post mostly because I just wanna get some more use out of this thing until I get the time to trade this with someone local or same carrier and research what might match how I was running with the Moto surnia from 2016 till 2018 only with modern hardware.
I realize I don't need all tbe extra crap features of a top end phone these days now that I'm getting back to my MS Surface for general things and realizing that there's a lot I simply can't do on a locked up divice no matter the specs.
Opinions on the wipe-update-uninstallUnneededFactoryPckes vs just removing all unused apps and call it a day till I can find something to barter for a decide more my style now that I know more would be great, as would opinions on devices that might be s good idea to search for locally to trade for. It is on my list of things to research and do over the fall season.
So yeah, thoughts/comments/rants?
I know there's a bit of info on this stuff around just hard for me to do full reseearch these days not tk mention keep up with everything I mean it took me what over a year now just to finally figure out how to use adb to disable and remove factory stuff as well as if people have opinions on devices to research that are like say the s9 modern with the Moto surnia openness I'm all ears.
I'll leave it there for now needed to get this down here or Reddit and back in the S4 and Surnia days XDA never let me down.
Thanks.
Just found a coupe things out like uninstalled apps will reinstall and evabke when you update.
|Ven with everything disabled over time reenabled it's running great again must have been getting rid of their cache and whatever plus I guess j got rid of the fake sd card finally confirmed it with that German mSD tool.
I think finding a model to trade for is best I don't need hardware this high end and j mean that new budget Indian Samsung model is basically as good or better for a fourth the price MSRP.
Gotta put some more research in but definitely dissapoijted the way Android and g{gke have gone since my Moto surnia days.

Firmware advice - SM-N975U - Note 10+

Hi All,
Been a while on here - please be gentle!
I have spent the last 6 hours looking into updating my firmware from Android 10!
I have done this on previous phones, but my current phone is proving a little more difficult. For the life of me, I cannot find the correct ROM to flash. Whenever I come to something I think I have found I seem to have another issue.
I've tried using various tools (Bitfrost) but got errors.
I'm in the UK, and as far as I can tell, my phone is “XAA”, “USA unbranded (default)”. I'm not bothered about changing the region code (unless it can be done easily).
Details::
SW ver.: SAOMC_SM-N975U_OYN_XAA_PP_0001
XAA/XAA/ATT
I would really appreciate some help from you guys who are way more informed and cleverer than me!
Thanks guys and gals!
Simon
EDIT: I have found a bit more informstion - I think I would be ok using SM-N975U1 - is this correct?
That's the umlocked Snapdragon variant...
I have two N10+'s; N975U/Pie, N975U1/Android 10. I would stay on Android 10 unless you want cpu cycle sucking scoped storage in all its glory.
Personally I prefer Pie to 10, better functionality and usability. With 11 you lose even more and 12 is fubar... in my opinion.
The best way to trash a stock N10+ is to mess with its firmware.
Rule #1 if a OS is fulfilling its mission, let it be!
Upgrades/updates can and do break things.

Thanks for that info ... I actually have no beef with A10 other than one issue which I thought maybe a firmware issue.
My NFC works (I can transfer files between phones) however, I cannot use Google Pay, or Samsung Pay. I have read somewhere that this was a firmware issue, hence my desire to update.
I have tried literally everything to get it working (cleared cache, re-booted). NFC Tools confirms it works, but it just does nothing at the checkout.
If I can fix this issue, I'll be happier!

You're welcome. It may be doing that because big sister Google thinks you need to upgrade to be secure. May have to do with the region you're using it in. I don't know. I never use those features and don't want them on the phone. Don't want anything to back door in using that route.
Depends how hell bent you are on having those features. You could easily lose more than you gain by upgrading, worse it may not resolve the issue. The N10+ is a valuable and reliable work horse that will run for years... just as it is. If it's running well otherwise I would try to find the root cause of this issue or simply use other workarounds rather than the shotgun approach.
Yeah, I was wondering about being in the UK with a phone registered in the US. But NFC doesn't read my credit card either. Would have thought that would be an option.
I'm not necessarily a huge NFC user, but the other day I forgot my wallet at the petrol station after filling my car. If I'd have had my NFC working, I'd have been able to fire it up and avoid the embarrassment!
Anyway, thanks for your help!
Be glad you have the Snapdragon variant. They are very reliable and run well stock when optimized. If you do upgrade to 11 a rollback to 10 isn't possible if you upgrade the boot loader.
There's always at least a small risk when flashing firmware which can trash the device. The only time I would flash a N10+ is if the rom was corrupted which barring a hardware failure is a very rare SUE, single upset event.
I never tried mine to see if Pay works nor have I ever set a screen lock. The fingerprint scanner could be dead for all I know.
The flip side to that is never being locked out* of my own device, no data lose, and double tap on/off. The device is glued to me as physical security is the only real security. I realize this may seem extreme to some, but it works well in the real world.
*a SEU or partial hardware can lock you out of your device. Had no lock been set, no lockout would have occurred. Got locked out of a PC bios like that. The password -was- correct
That caused a mountain of trouble...
Thank you my friend. Wise words indeed and duly noted...
