[Q] Problem regarding super user and USB connection

Dear All,
I have encountered a problem with my note 2 that unfortunately closes a lot of doors for me to fix. I thought about asking you guys and hopefully this has not been asked before. Ok so my problem is that I had rooted phone ages ago and i had SuperSU installed with the root. Later on some official update came out and I let it update. After that I might have lost my root there and then not sure though. When I try to do something in root it won't let me, also it fails when trying to change super user app. What is killing me mostly is that any computer I connect using different cables, won't recognise my phone, as if it was not even connected although it charges normally. At first it was sometimes charging and not, sometimes freezing if connected to the USB. It might be hardware related but I want to try to fix this issue first to be sure. I can't even use Odin since it's not being detected so unrooting and going back to the seller is out of question.
Can anyone help me please? I am thinking of trying custom firmware through sdcard installation but i cant even install CWM and when using official recovery the package is not accepted. (signature issues). There may be some easy workaround I do not know of hence me asking you experienced guys.
Big thanks for reading this and hopefully helping me.

So you mean odin is not detecting phone in download mode ?
Try connecting the phone and see if adb works but I don't really think it would work. Try another cable. Could be that usb port is damaged.
Try another recovery.

No, Odin is not detecting the phone although it starts charging like normal. I will check adb later tonight when I am on my home pc. I have tried in total 4 different cables same result. I have used 3 different operating systems on different computers, still not detected. Usb port might be damaged but I don't think they will be happy seeing its rooted.(they being the store i bought it from, that is why I have not gone to them yet.

I have a similar issue since 4.1.2 however my phone is recognized by computer and odin in download mode, are you sure you tried it on download mode?

Yes I have tried download mode, that's why this problem is killing me :/ The root access is completely unusable and not working too.

[Q] USB device not recognized, half rooted, no custom recovery--Totally messed up!

Here is my problem where I can't get my Sprint S3 connected to PC, I am half rooted, and have no custom recovery, I can't flash anything on my phone except OTAs, please help, any help is much much appreciated.
Background :
I had this phone working completely fine, I bought aftermarket USB cable and attached it to the PC, everything went smooth it got connected fine in MTP mode, on second day when I tried to connect it, it gave me error that USB Device Not Recognized.
Problem :
The phone is not getting connected to PC in any way, whether it is MTP, DM+Modem, PTP, ADB, etc... not even in download mode to flash it via Odin. No matter on which mode I am it always give me error that USB Device Not Recognized.
It sense when I change modes while it is connected to PC, like when I am on MTP and I click DM+Modem or I click USB Debugging, it displays that USB Device Not Recognized message again, so I it is sensing mode changes.
What I did so far :
Changed cable and used brand new Samsung Original cable, changed USB ports, changed 4-5 computers, installed and re-installed drivers numerous times, my friend who does the phone repairs changed Micro USB Slot on the phone 4 times with Original ones, he even took one from working phone and put in on this phone, no luck so far.
My inputs :
I've searched really a lot about this problem, but didn't find any single solution.
Some guys on forums reported that they solved problem by flashing a stock or custom rom as there might be a problem with Kernel.
I can't flash anything on my device since I am on stock recovery and half rooted, I had LJ7 rooted stock on my device, and I took MD4 OTA, now, my phone is half rooted, when I install any application which requires root, I get message that 'Superuser permission denied'.
I can't even uninstall Superuser, because it is system app, I tried to re-root phone via Motochopper method but it doesn't work.
I flashed this phone to different carrier, so, I am afraid I will loose my flash if I take latest 4.3 OTA.
PLEASE HELP IF YOU HAVE ANY SOLUTION FOR THIS PROBLEM, I WANT MY PHONE TO GET CONNECTED TO PC ANYHOW.
I AM READY TO DO ANYTHING YOU SUGGEST TO RECOVER MY PHONE.

Did you uninstall drivers from Windows device manager before reinstalling drivers? I found that this sometimes helps.

[Q] N900T Semi-brick help!!!

Hi, Need pointing into right direction. I use my note in the uk and tried flashing different roms, modems etc to get LTE to work. It stopped connecting to my laptop at some point but I continued to flash cutom roms using recovery. I then tried the Odin app (by Chainfire) to flash stock Tmo F1 rom. I had been on NE6 prior to me trying custom roms.
Problem is that the flash failed (when rebooting itself) and is now in a bootloop and I can't get into recovery either. Download mode comes up but it does not connect to the Laptop. I have tried Odin, Kies, reinstalled drivers but no luck. If I connect directly to the laptop the phone does not come up but if I go through a USB hub it recognises something been plugged in but fails to install driver.
Now i know i've messed up but was hoping if there is anyway I could use the sdcard to help boot the phone maybe into recovery or somehow get laptop to recognise the phone???
Any help would be appreciated as I did enjoy the phone and have spent not days but weeks on this problem and the Mrs aint to happy either...thx...

Your current problem is drivers. Get that fixed, I can't help much as I don't run Windows often. Perhaps a boot disc with Linux/Heimdall might help... Lose Kies, it can't help you right now and it might have messed up your drivers, uninstall it and reboot. You need Odin. And not the app, the real one on a PC.
If you have an N900T, the Tmobile NF1 is the one you want. Try the Effortless guide in the general forum for detailed directions and good files to work from. If you can boot to download mode but Odin can't see it, the drivers are messed up on your computer. It's not the phone that has an issue. Try a different computer if you can. The Samsung drivers can be a bit picky. You might need to go to Device Manager and uninstall the drivers while the phone is connected, disconnect and reboot, then try to install the proper ones again.
And if you're in an LTE area, you should connect without any changes. Trying to force it is a bad idea as you probably don't have a network to connect to.

Thanks. Did cross my mind about the driver issue but my S3 connects to the laptop fine. Or do you suggest I give the Linux a try?
Also would the lte bands works here in the uk considering it been a us tmobile?
Tried linux/heimdall but still doesn't connect to my laptop. Don't know what it could be. Any ideas please guys.
UPDATE.....resolved by replacing USB charge port as a pin was damaged/broken.

[Q] When Root goes bad.

I successfully rooted my friends Fire Phone by downgrading to 3.5 OS.
After the root was done, everything was performing well. EXCEPT TWRP. TWRP would not install no matter what I did, not sure what went wrong there...
Anyways, my friend decided to factory reset which led to a bootloop I have never encountered before. I can get to the screen where it asks to register device, then it asks whether or not to enable location services, then it asks to register device, going back & forth......
Im fairly sure this is because of a reset while rooted without TWRP.
I have tried toolkits to unbrick, followed steps through adb, seems like nothing works.
Even more annoying is that there is no way for me to turn on the USB debugging on the phone (since factory settings were reset), so command prompt does little good. I can see the device showing up in my computer though. Just no way for phone to allow the access.
I have rooted a few phones, but never one with this much trouble. Any help is greatly appreciated.

Does anyone have a system dump? Or know where to download one for Fire Phone?
Dont think I can fix the phone without it. & then I still have to figure out how to get usb debugging "on" while not being able to get in settings, so that ADB command can connect with phone

I broke my 3.5 install too, but got it working again by sideloading 3.6.2 and then going to 3.5 again. Each time with full reset. Have you tried that?

It wont show up in sideload b/c i dont have usb debugging on. Thus, my problem. Ive tried that many times. I have correct drivers. I was using ADB prior to my factory reset. Now, its screwed haha. Amazon will be ecstatic

I dont think that twrp or any custom recoveries are available on the Amazon Fire Phone. Installing the twrp was likely the issue. Not the root. I can factory reset my rooted Fire Phone with no issues.

Did you ever solve your problem?

My G2 wont mount to PC but does charge.

Hi guys i have a weird situation I recently updated to lollipop OTA and my usb stopped working it wont mount to my pc I've tried everything from uninstalling drivers to reinstalling to using different PCs to cables and nothing seems to work. Although my phone still charges when i connect it to the wall plug and also on the PC the only thing is it doesn't even get recognized by my computer it just don't pick it up. 2nd thing i found was i tried launching download mode to see if i could just restore it back to 4.4.2 but now my download mode is also gone I'm assuming that when it updated it all got corrupted is there anyway i can fix this? I forgot to mention my phone works properly it boots up fine and everything.
