[Q] USB Not Recognized. - Galaxy Tab Q&A, Help & Troubleshooting

So I got my Samsung Galaxy Tab (sprint CDMA version) today and when I first plugged it into my computer the drivers installed fine. I was able to mount the sd card and transfer files with ease. I then proceeded to root the device hoping to put a new rom on it, I've got a captivate and am not a rookie at all when it comes to flashing roms via odin, cwm, etc...I first put the device into debugging mode which is where things got weird. As soon as I put the device into debugging mode and plugged it in via usb it immediately became "unrecognizable". I have the correct updated drivers for the device both from the Samsung website and via the Android SDK tools. There should be no reason why this happened. So I then took it out of usb debugging and plugged it back in and bam, again, "USB Device not recognized". I've been installing and uninstalling drivers, the device itself from the device manager, and have been trying other numerous ideas. I've been Googling and searching for hours upon hours at this point and don't know what to do next. Odin does NOT recognize the device when in download mode and the device does charge when connected to the computer. I have tried a different cord with the device and different computers and it's all the same story, works until debugging is enabled then it will no longer work no matter what. I am fairly sure at this point the device itself is malfunctioning or defected but I wanted the opinion of others before sending it back. I am pretty sure have tried everything and am doing everything right. Please help if you can, if not I still appreciate your time! Specs are listed below:
Hardware Version
P100.08

1. Just wondering, have you installed Kies before connecting the tab to your PC?
2. The SGT will not charge "normally" with a USB connection. It will trickle charge, which is very slow way of charging, and the device will not indicate that it is charging. Does your device indicate it's charging? (As stated above)
Hit thanks if I deserve it..

FWIW, My SPH-P100 Sprint Galaxy Tab has been an adventure as well. Enough so that I wish I'd known more and held out for a GSM model.
I am not even sure if Kies and/or Odin will in fact work with the Sprint GT. I've had almost no luck with a variety of attempts. Even the widely used ClockWorkMod Recovery does not include the Sprint GT among its list of supported devices. It does include the CDMA Verizon GT - and some folks have posted that they eventually got that to work.
I did get the SuperOneClick to work and setup root privileges on my tab. That part works fine. But so far I've been reluctant to experiment too much with the various tools that "almost appear that they should work" as I have too little experience with this Android tablet environment to feel comfortable that I can recover from the eventual disaster.
Am hopeful that Samsung will in fact follow through on their commitment to provide upgrade of all GTs to Gingerbread 2.3.3. If so that may be enough for my needs. I WOULD like to get the Netflix viewer app working. Is frustrating to already have a Netflix account and not be able to access it via my GT. A guy down the hall can get Netflix on his Droid X - which really bugs me! lol
IMHO, Google/Samsung/Motorola/HTC/etc. have done a horrible job rolling out Android - both on phones and tablets. Netflix really highlighted this when they decided to do device-by-device testing and certification before allowing Android devices access to their movies. Apparently the 'capabilities' inherent to various Android devices varies so much (and not just OS version) makes it difficult to roll out something as simple as Netflix access. It is frustrating. And the only "solution" so far is to wildly 'hack' your device in the hope that you'll shake something loose enough to make it work as you wished it had when you bought it.
Enough whining for now. But it has been a very frustrating and disappointing experience.

I installed Kies AFTER installing drivers and connecting the tablet and it has no effect. I also learned after googling that kies does not support the sprint cdma version though I could be wrong but many people have stated this. And the device does charge and does so very fast actually, 20% to 100% in 4 hours. I don't think it's trickling down as you say because it is very clearly charging at a fast pace. Thanks for the quick response though! And I have also tried superoneclick root and other methods i.e odin but neither can find the device. I know some people have had luck with this sort of thing after upgrading the rom and/or flashing firmware onto the device which I would love to try but unfortunately without windows being able to see the device, none of this is even remotely possible.

I think the reference to slow charging on USB is really refering to using a data USB port on a notebook or desktop computer. This is because the data USB ports are limited in how much current they will pass. My SPH-P100 will in fact charge on a data USB port - but very, very slowly. In fact if the device is ON it may just barely be breaking even.
The USB charger is certainly capable of charging at a very reasonable rate.
I'm still waiting on the 2.3.3 update that Samsung has promised. It only took them 5 months to get the 2.2.1 update out for my Fascinate! So maybe we'll see the 2.3.3 update by Thanksgiving...or Christmas...or...

[SOLVED] USB Device Unknown

After racking my brain for a few days, a couple hours each day, I've fixed my issue with my device being unknown.
Let me start by saying I'm flash happy, and everyone that knows me personally, tells me to just quit jacking with my phone. NOT A CHANCE! I'm on my 3rd Cappy and shouldn't have ever exchange it again. I only had to in the beginning, because I was a newbie and had not know enough, but to get me in trouble.
I presume that this should work on all Windows OS's. I personally am running Vista Enterprise x86.
My symptoms:
Plug in phone to the usb and it there was about a 15% chance off being able to mount to usb, and Windows recognizing as a mass storage device. I tried un-installing drivers and re-installing and it would work some of the time, until the point came when parts of the driver install would fail. Then to the point when it was just completely unrecognizable. I thought I had it fixed because it seemed intermittent. In the middle of flashing to stock, something interrupted communication between the pc and my phone. Restarted the phone and attempted the flash again. Got a little farther and froze again. I had to use another pc that I had never connected my phone to before and I was able to use my jig to trigger download mode, because no buttons combinations would allow it into download mode.
This got me thinking that it was specific to my pc and not my cable or my phone.
My resolution:
I went straight to the registry and went to find. I deleted every entry that came up for "i897" and "i9000" excluding what was listed in the system volume information, as I didn't have permissions to remove any keys. I didn't keep count, but I probably deleted 300-400 registry keys that pointed to my phone. It seems as if with each developers rom that I had flashed, there was an entry for a different device. Don't quote me on that, because it is just my personal consensus. I also un-installed the samsung drivers, the unknown device driver, kies software, and anything associated with samsung. I noticed that next to all of the i9000 instances, the hex key for me started with 1000ee. So I also searched for the first part of that key trying to ensure that all instances of the device. Lastly, I deleted the samsung folder from program files.
I installed the samsung drivers package commonly listed in all of the other threads for x86 operating systems. I plugged in my phone and watched as each and every driver installed successfully. Keep in mind different drivers are installed depending on if you have usb debugging on/off, and the options for if the preferences on you phone are set to media, storage, or kies. I have multiple usb ports, however testing has shown me that, for me and my setup, I can plug into the port that I used when installing the drivers the final time, I am able to connect consistently. Earlier today, I tried to plug into a different usb port and it was an unknown device. I am led to believe, this is because I didn't un-install the unknown device on this particular port.
If you intend to work in the registry, please remember to always back it up first. You can always restore.
Hopefully my findings can help you as they did me. Happy flashing and I would like to thank the community for the dedication to assisting each other and the developers, for making flashing, better than crack cocaine. Flashing rom's doesn't make you twitch near as much as a crackhead.

[Q] S Advanced not turning on / charging - Help needed.

Hello all,
I need some help. So a family member of mine was recently handed a Samsung Galaxy S Advance to use and it was my intention to see if it were possible to unlock the phone (from Orange UK) allowing her to use her own network on the Samsung. Now I've rooted android tablets a good few times and it's been a breeze but this phone as proven to be a nightmare all day. Basically I decided to use Odin3 to give the phone a clean standard firmware for me to start with (2.3.6) and Odin went fine, in the end it informed me that it had past and I thought everything was okay. But now the device won't start up at all or charge, the only thing that appears to get a response out of it is if I connect the USB cable, disconnect the battery then my PC will inform me of a connection noise and then it suddenly disconnected seconds later. Have I done something wrong here?
Unfortuantly I can't access recovery or download without the screen even turning on. I'd greatly appreciate some help. Thanks.
Hi,
sorry to say but your device is fully bricked.
What you hear when connecting it to your computer is the IROM software or the device probing to see if there is the correct server to connect to.
You need the libusb drivers correctly setup for you computer to recognize the device in this mode, but that is not enough, you need the correct software to talk to the device too.
Some times ago, I have managed to setup such a server (I got the software sources from someone here who gave it to the community) and talk to the device in this mode but never had enough time to experiment with it to send a minimal bootloader (documentation provided with the software is very minimal and somehow "cryptic").
Nobody here ever tried to build up on my searches, having no more time to play with this + this phone starting to be really outdated, I gave up.
Regards

Nexus 6 no longer recognising PC (and PC no longer recognising phone) in Fastboot etc

Around February, my phone was working fine and connecting to my PC and being recognised (in both the phone AND PC/Device Manager). Because I was rooted, I used Wug's toolkit to flash the latest factory image at the time (which included the February security update) and kept data as I've done in the past. It was fine for ~2 weeks after that factory image flash and then my phone just stopped recognising the PC, and my PC stopped recognising the phone as a device. It was completely out of the blue, and seems unfixable.
When I plug my phone into my Desktop - it just charges. It doesn't appear in the device manager at all (image below - Device manager WITH phone plugged in and not appearing):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I've had to do the old 'update drivers' thing in the past with other phones, but they would normally appear under "Phone" or "Other devices" - but both are missing from the list ("Show hidden devices" used in that image). There's also no yellow triangle to say an unknown device has been connected. It just flat out doesn't know it's there. I've also updated/re-downloaded the SDK (and Google drivers) but the phone still isn't recognised.
It got so bad, I had to use USBDeview to uninstall the drivers in the first place because they never appeared. It still didn't help.
On the phone side of things - I'm not given an option to mount the phone as any form of storage. It just behaves like I've plugged it into a charger.
In the USB and Storage settings (image below) - I'm not given an option for ANY form of USB connection.
And in the notification shade (again, while plugged into my PC) no option is given. It just charges:
I've also tried factory resetting the phone, since it charges fine so I don't think it's the charging port but now I've lost root AND the problem is still there. I still can't install OTA updates because in order to get Root, I had to use a kernel which disabled those "this device has been modified" alerts when you boot it, which means the OTA just fails (Error 7 (or 6) - and something about recovery).
In Fastboot, it just says it's 'charging' and makes no attempt to connect via USB. Recovery is the same so it doesn't sound like an Android problem per-se since it affects Fastboot but hardware wise - would could it be?
As a last resort, I've also tried multiple cables (working one for the Nexus 7, DS4 one and a Motorola one) and none of them seem to have helped.
I've also tried different USB ports and on different machines - both running windows 10 and both with the drivers installed but still no luck.
Any help would be greatly appreciated because I'm just sick of this problem at this point.

You've tried a lot.
My idea is to try to connect to another PC, when possible not Windows 10.
This to check that the problem isn't caused by the phone.

That's a very good point. Pretty glad one of my PCs didn't like the 10 upgrade and is still on 7.
I'll try it when I get home. Thanks for the reply!

If changing PCs doesn't help, try a different cable. If that still doesn't work, you likely have a problem with the micro USB port.

Tried 3 different USB cables and no luck.
I've got a spare microUSB I bought from eBay which I'll need to solder but the only thing I could find on faulty ports were that it doesn't charge right but mine does.
Going to try connecting it to a windows 7 laptop and see where that goes. If it still doesn't work - the only thing left would be the port itself which will be a pain to replace (and still doesn't guarantee it'll be fixed).
Honestly it sounds like a hardware issue with the MicroUSB port. I can confirm it works fine under my Windows 10 PC at home, both normal access for files and I've also had no issues with using fastboot or ADB. If it's under warranty try to RMA it. If it's out of warranty see how much it would cost to change the MicroUSB port from a local shop or try it yourself
I've had the same thing happen to me twice. I think that some times Windows updates and kills the drivers. Whenever it's happened to me I've installed a universal adb driver that's floating around XDA. Once that alone fixed the issue. Once it didn't. The time it didn't I had to open every device heading in the device manager until I found one that had Google hidden inside it. I uninstalled the Google driver from there in the device manager and then plugged my phone in. Windows did the normal device install from the phone and all was fixed. Hope that helps. Good luck. Windows 10 truly sucks.
Maybe to rule out pc, find a buddy with android phone and see whether you can detect it with adb or fastboot on your pc. I think those drivers are supposed to be universal (all phones)....aren't they?

Tried it on my Windows 10 laptop as well and it's the same problem. Just tried it on my older Windows 7 laptop as well, and same story.
My older Nexus 7 2012 connects fine to all 3 so I don't think it's the drivers.

Sadly already tried this but what's worse is - I've looked through all the possible 'dropdown' options and the drivers/device doesn't appear but it appears in USB Deview (where I uninstalled them).
Tried both the universal ADB driver and Google's own one from the SDK - sadly didn't work in the end.

I'm beginning to think the same to be honest. It doesn't connect in Fastboot, which leads me to believe it's more hardware than software because if it were Android itself screwing up - it would at least work in Fastboot as that doesn't touch Android.
It doesn't mount as anything, so I can't access my files on any of the systems I've tried. I've even tried my younger brother's laptop and it doesn't 'see' it (but his Nexus 4 connects and works just fine).
I bought my Nexus 6 ~6 months after release so it's out of warranty (what a time for it to run out of warranty). I bought a new USB port from eBay ages back so I might have to fit it myself since all the repair shops I've contacted would take ~3 days to do it and I need to have a phone.
I really hope replacing the port will fix it. It charges fine, which makes me slightly worried it won't work (as it's not an obvious port issue) but I can't think of anything else which could be the problem.
Thanks to everyone who's replied though! I'll see how the USB replacement works out.
Hello all, long time lurker 1st time poster....
I've never really felt the need to post because i normally just do a search and work things out for myself, but i'm now having the same problem and noticed this around 2-3 weeks ago after trying to copy some pictures i'd taken onto my Laptop from my Nexus 6 and it not being recognised, only charging.
I've tried EVERYTHING (apart from reverting back to Windows 7) mentioned in this thread and in a couple of the other threads i've found where a few Nexus 6 users have had the same problem. I'm now stumped for ideas.
My Nexus 6 runs as flawlessly as usual, no battery drainage, stutters etc.
I'm currently running Temasek's 18.2 (5.1.1) rom, and have been using it now for a long time (probably for 8 months or so with absolutely no problems whatsoever). I've updated to MM a few times and tried a few different Roms, but to be honest i just found that LP worked better for me so have always just reverted back to the last official LP 5.1.1 LVY48I Rom using Wugfresh's Tool Kit (i know i know , but having rooted/played about with other Samsung/HTC Phones in the past, i just preferred to use it) and then restoring my backed up reliable Temasek's 18.2 Rom.
So, what else can i say....well, i called Motorola around a week ago for some advice, just incase there is a potential warranty claim (because my Nexus 6 is only around 9 months old), but as i have a Custom Rom on it, they said that there is nothing that they can do.
I do have an official clean 5.1.1 Rom LMY48M that i fortunately backed up to my TWRP Folder on my laptop just after installing TWRP+rooting. I did 1st of all also try connecting my Sandisk Ultra Dual USB DRIVE 3.0 to my Nexus with the Rom on there, but the Nexus just doesn't even know that the USB Drive is connected, so I have had to send it via bluetooth to my Nexus from my laptop, as that was the only way to get it on there. I found that Zipping the file 1st, sending it to my Nexus via Bluetooth and then extracting it once i'd received it saved hours in time because the file was too large in its original form (something like 4+gb down to 1.9gb). I've also tried a few other LP Rom's in the last couple of weeks, hoping that maybe i'd accidentally switched a setting off or something and that the phone would correct itself and my connection problem would correct itself but i've had no joy.
NOW...........................probably a silly question but it's the only other way i can think of returning to Stock for a potential warranty claim. I know that i can install the official 5.1.1 Rom i backed up via TWRP because i've tried, but is there a way to remove Root+TWRP and return to Stock Recovery+remove root without using a PC ? I'm pretty sure that there isn't but feel the time is right for me to ask the Question as i'm really not 100% sure.
Many Thanks in advance for helpful advice given, like i've said at the start of this post, i've held off asking Questions before because i had no real need and just searched :angel: , but this has really stumped me .
CHEERS
Some quick thoughts.
1. The Motorola rep you spoke to I think read from a script and didn't realize you were talking about the Nexus 6. As this is a developer device, having custom software on it should make no difference for warranty purposes. If I am mistaken however, read on.
2. If you're going to install a stock ROM on the Nexus 6, a PC will be required, especially if needing to replace TWRP with the stock recovery. So why not download the latest Android 6.0.1 image from Google's Nexus firmware page and flash that? There's no point in reverting to an Android 5.x image simply for a warranty claim.
Many thanks Strephon Alkhalikoi for your quick reply and sorry for my slow 1 (work was getting in the way....)
1 - at some point today, i hope to chase my potential problem up with Motorola or possibly Expansys because i purchased the Nexus 6 from them via Play.com/Rakuten.co.uk
2 - The 5.1.1 Stock image that was going to be put on the Nexus was only a normal TWRP back up i'd saved by chance straight after flashing+rooting that i had saved to my Laptop. There is no way for me to flash any new Stock software because my Nexus is just not recognised by my Laptop. I've tried installing+uninstalling drivers/Minimal ADB Fastboot file/Wugfresh's Toolkit, plus Developer options usb debugging on/off etc and Settings/Storage/USB Connection (3 little dots top right) which gives me 2 options Media Device (MTP) + Camera (PTP) but after changing either, still no sign of connection, just charging.
As it stands it works fine on 5.1.1, but with me not being able to Flash any Stock Roms because of my Laptop connection issue, it will be forever more on LP. I could put up with that but obviously i need to try and sort this out also because i can't transfer normally any media files backwards/forwards (only via the much slower Bluetooth) and it will affect any future sell on value when it's time to move on.
Many Thanks once again
**Latest Update** for those not asleep yet....
i spent nearly 20 minutes on the phone around an hour or so ago explaining my problem to Motorola. It's not something they've heard of before so couldn't really help and that by being Rooted, their repair center will not touch it. I can only think that if i'd purchased the Nexus 6 straight from Google, it would not have been such a problem to handle a Rooted device so it would have been taken in for repair i'm guessing.
It was explained to me that i would be contacted via email once a technician had been consulted and here is the reply i received a little while ago.
"Thank you for contacting Motorola.
As promised, I have spoken to a technician who has a couple of suggestions.
A. As we discussed, he also suggested connecting your phone to another computer.
B. Be sure that you have Windows Media Player and the PS Drivers installed on your laptop.
[link removed due to my lack of XDA posts]
C.
At this point, I would like to suggest that you restart your phone on Safe Mode.
Safe Mode puts a phone in a diagnostic state and it can help us determine if a third-party app is causing the device to malfunction (freeze/reboot/run slow/error message). Safe Mode temporarily disables all applications that have been installed via the Google Play store. Performing this troubleshooting step is necessary to determine whether a third-party app is the cause of the issue you are experiencing.
Please long press the power button > long tap on power off > reboot to safe mode >ok.
If you find that the issue is resolved in Safe Mode, please delete all apps from the phone, and gradually add them back one or two at a time, until you are able to identify which is causing the sound issue.
To move phone from Safe Mode back to normal mode, you can simply restart it.
D.
To be sure if the problem is software or the port itself:
1. Reboot phone in Fastboot Mode
2. Plus phone into computer
3. If phone is recognised as 'Fastboot Shamu NS,' the issue is software, rather than a physical issue.
In this case, you would need to reset the phone, which I know you are hesitant to do, but you should then be able to reflash the factory images, available on the Google website.
Unfortunately, there little else that we are able to do to help you since, as discussed over the phone, SBE UK, our repair, centre will not accept a rooted device.
For any further assistance or information please do not hesitate to contact us, quoting your Customer Reference number. We are reachable on 03339 997 550 to discuss the matter further with one of our experienced customer service agents. Please contact us any time between the hours of 8am and 8pm from Monday to Friday.

SBE repaired my nexus 5, when it was rooted/unlocked.
Is there any damage to the usb port? Never tell the customer service rep that your device.
Cheers for the reply JonesL
As far as I'm aware, there isn't any damage to the USB Port. I did say I thought that that might be the problem but she said if it was the reason, then the phone wouldn't charge at all.
I could still send it in and hope that on the off chance they don't check for Root, but i will be liable for the postal returns plus the hassle of being without a mobile whilst it is away. Also, I've now given my IMEI number and a couple of other details so I'm sure I'll now flag up on their system when its checked.
Oh well....

[Q] Unable to recognize phone when hooked up to computers

Hey folks,
So I have a completely unmodified, stock Canadian N920W8 on 6.0.1, and no matter what I do, I cant get it to be recognized by Odin on my Win10 or Heimdall on my Mac.
I've done everything I could think of. Different cables, different ports, even different computers. Reinstalled the USB drivers, everything.
Anyone have any ideas? My phone won't fast charge, and is lagging more and more. I can't even Odin back to stock because it won't recognize. Factory Reset just cleaned out everything but nothing has changed. OEM unlock and USB debugging on, it won't be seen by the computers.
Any help? It's past manufacturer warranty, but it's still a good phone and I don't wanna lose it.

Did you install the actual drivers or just the ones that Windows installs? I use the ones that Samsung smart switch installs and I have no issues. If it is not fast charging and your computer does not recognize the phone it may not matter what drivers you use.
I used the Samsung USB drivers for Mobile Phones from Canadian support page. And that's on a fairly fresh win 10 install, too.

If you can I would suggest installing smart switch and see if smart switch sees your phone.

I tried it on the Mac, smart switch didn't see the phone booted up. Didn't get a chance to try it in Odin mode. I'll try that tonight. And also on the PC. Any other suggestions?

Unfortunately not. I was hoping smart switch would see it. I would not rule out a damaged USB port.
I hope not... this is way past warranty, and I wanted to flash the thing with Khongloi's new Nougat rom... if it won't be recognized, then I can't even back it up or re-flash it to stock. Which is not a good thing...
No other suggestions, @CodeNameRedNeck ? You've been a huge help otherwise.

Just to be sure. Can you transfer files from your PC to your phone and vice versa? Do you have any USB 3.0 ports? My phone seems to work better on 3.0 but still works on other types. Do you still have the Samsung cable? I know you said you have tried other cables but I used to have two cables that would not do data.
I tried with a brand new from the box cable, into four different usb 2 ports on the Mac and 2 usb 3 ports on the windows 10 PC.
No luck with it even being recognized for file transfers either.
@ve6ay, I could be wrong but I would say you probably need a new port. You should be able to pick one up relatively cheap. Good luck.
That's my thought, too, and in that case, I'll forgo anything. The contract is up in October, and it got the OTA update to 7.0, so I'm okay with it for now. I'm not into opening up her phone (which hasn't even been rooted yet) to switch out a port that I'm not confident enough to switch out.

Did you try going into Developer Options and then scrolling down until you see "USB Configuration" and setting it to MTP? Or open the dialing pad and enter *#0808# and then making sure it's set to MTP, ADB and then try again.. If that doesn't work then it really is your port connection and it's actually super easy to replace and cheap too! All you'd have to do is heat the back up so you can loosen the glue up and then slowly pry the back off and then remove like 16 screws(lol) and then at the bottom you just unscrew it and easily pull the thin connection out.. I've done it several times so far although trying not to break the back glass is super hard..
The back glass got shattered in a drop last summer. So that will probably be a problem. Like I said, new phone this fall, most likely the next Note series. Though I'm tempted to go with an Exynos variant from across the ocean.

Cannot get USB MTP to work on T-Mobile SM-G781U

Hi, I really hate to make a new thread, but I just cannot get this darn thing to connect to my PC. I had a G900A (S5) for over 4 years, rooted w/custom rom. I had/have a G935F rooted with SMan custom rom on Android 8. They both work fine (well S5 died a bit ago...LOL). I downloaded the newest Samsung USB driver, which installed fine and the G935F still works. I tried it both on my W7 Pro desktop and W10 Home laptop.
But this damn S20 will absolutely not connect (using same cables on both, except of course the S20 uses USB-C). This THING is on Android 11 (sucks to holy hell). I enabled the Developers Option and enabled USB Debugging and then changed the USB Default config from Charge Only to "Transferring files" and still NOTHING (of course I can say that it Does charge).
I have looked Everywhere. Called useless T-Mobile and they did not know. I got it on Friday and going to the store Monday. Can anyone solve this and save me a trip or do you think something is wrong with the hardware (it's brand new out of the box)?
THANKS!
does windows recognise that a phone is plugged in or not. use the original cable if you're not and swap which USB ports you try on the PC/laptop.
there is supposed to be an issue where MTP screws up large file transfers but it still recognises the phone.

Was it v1.7.43 and did you remove 'any' old driver versions before installing -
- https://developer.samsung.com/mobile/android-usb-driver.html
And when plugging in the phone for the first time you may have gotten a prompt to allow access, if different/more annoying under Android 11 afaik.
And on a different but Android 11 front, can I ask what bits sucked or were different to 10 for you on this device?

Hey, did you mean to quote without replying..?
Hi, I said I installed the newest (that is the version) and did it before I even got the phone and my 935F worked fine. But no, I did not uninstall the old one. It knew it was there and it did it. I have updated the driver the same way in the past and both the 900A and 935F always worked.
Also I think I said what versions I had on both phones, which were android 4 + 5 on the 900A and 7 + 8 on the 935F.
It NEVER asked me Anything Anytime I plugged it in.
I could actually live with this phone (made so cheap, by the way), if I could just get into it and complete putting my files on it. Also THIS phone is draining battery a bit Because I can't root it to get rid of whatever bloatware crap is on it (any suggestions on that?).
Plus I don't like all the crazy crap it displays and does. ALSO, CAN THEY KEEP MAKING THE CLEAR BUTTON EVEN SMALLER???
Attached is a pic of my beloved S5 BEFORE GOOGLEY SCREWED UP ANDROID, THAT THEY CREATED TO BEGIN WITH...Grrrrrrrrrrr...THOSE WERE THE GOOD OLE DAYS OF REAL ANDROID...LOL.
Thanks anyway for the reply!
PS, sorry I been away from the forum for a while. Things are a bit different now! Sorry, b1k3rdude!

Hi, I did try the same "extension" cables and ports that I used for the 935F, but I had a USB-C laying around for my bluetooth and used that and never thought to use the original cable that came with the box (still in the box). It Never recognized the phone ever. I will try that...If it works I am going to bang my head against the wall because I spent hours trying it and researching it and even uploaded certain files to my google drive just to get them to the new phone (I Was Determined)!!!
I will try it and edit this with the results. Thanks!!!
Son of a B*tch, that worked! The cable that came with the BT did not work, but the original one did right away. I did not know that it installs separate drivers for different phones! It installed all the drivers and the phone asked for permission and Voila! Even worked with my old USB extension cable. I never would have thought of that.
THANK YOU, THANK YOU, THANK YOU! See, when I got up I went to look to see if anyone answered before I even took my pills and etc...Now back to all the disastrous news. I am a H Andrew "victim" and feel bad for the people of LA, and of course what happened in Afghanistan. So off to the News...
Also may I ask what is so special about the cable that came with the phone as opposed to the one I used from my BT??? Thanks!
So on another note, any tips on how to get around all the crap of UNROOTED Android 11?
Also, do any of these rooting threads really work on this US version of the phone? For sure this darn BL is locked. I did find a procedure to tell. A bit complicated (for me), but now that I can get into the phone, I can surely try.
Also I miss my Viper for great sound. Anyone know how to replace it with something if I can't get this rooted? AND WHERE THE HELL IS THE HEADPHONE JACK??? LOL. Plus, do you know how long it took me to figure out how to just get a screenshot on this THING??? JEEZ!
We switched to T-Mobile from ATT and this phone cost me Only $99 over 24 months + $49 tax, while the other 3 on the family plan got their usual rotten apple (I-12's) for free plus tax. I Refuse to get one, but I am an old time programmer and can't see my way to a rotten apple...yet...LOL
Thanks, Sam in FL
Also, I must say that this 5G here actually works in spots (not in my condo though). I got over 500 Down and 49 Up near me, then got depressed when it did not do that in my condo, but I got wifi anyway and who really needs that much down anyway???
Samsung's cables designed for data transfer and flashing are not the same as off the shelf data transfer cables (unless it's made by a decent manufacturer like Anker).
for getting rid of the crap apps, look up ADB debloat threads for Samsung phones, the newer the better, one close enough like S20 or S21 will do.

There are some S20FE specific ones in this S20FE section.
