[Q] Complete restore without USB

My GNEX is having some issues. A couple of weeks ago, the phone froze when I started the camera app. Not a disaster in itself, but when I pulled the battery, the phone wouldn't boot afterwards.
Now, since I've got CWM, a backup and factory reset was a breeze. I could now boot the phone again. But if I tried to restore from the backup, the phone would go back to bootloop.
The phone has been acting a "bit off" since then, with the occasional freeze and quite a few FCs.
Yesterday, a new problem surfaced. The phone refuses to connect via USB, and windows complains that it cannot recognize the USB device. The phone also either refuses to charge, or believes that it is charging when the cable is not plugged in.
So, I tried a complete reset and a new rom. No joy, the USB-problem still occurs. I've tried leaving the battery out for a while, without success.
So now I'm hoping to restore the phone completely and return it for service. Problem is, how can I do this without USB? Flashing the stock rom from CWM is easy, but how can I flash the bootloader and recovery image?
Transferring files to the phone is easy via eg. Dropbox.

You can use the Odin repacks and flash them with mobile Odin.

True. But my bootloader is locked. I re-locked it after installing CWM.

Oh you lucky fart.
I'd neeever get that lucky to have my bootloader locked and my phone ****s out.

[Q] Can I get root w/o USB?

So the short question is if there is any way for me to get root without a working usb port?
Last week I plugged in to charge my phone overnight with the phone off. In the morning, I was surprised to find that the screen was on and what should have been a full green battery was instead a scrambled image that kind of looked like a battery. I powered on the phone and it worked so I thought nothing of it but later on that night I needed to pull a file off my phone via usb and realized that the phone will no longer detect the usb host, ie. no mtp options whatsoever. It at least does still charge.
Since then I have tried cleaning the usb connector, pulling the battery/sim, setting the UART using *#7284#(PDA, mtp+adb), multiple computers, and multiple cables(including the Samsung one) and the phone still doesn't ever think its connected to a host. So today I decided to use my php warranty service which meant I had to restore stock recovery and rom. So I grabbed mobile odin and a stock UVLDJA image. Ran Triangle away once to clear the counter, and another time to verify it was at zero, and installed the full image via mobile Odin. When the phone booted back up, it successfully installed the rom only the flash counter is back at one and now I have lost root. If I had used my head I should have flashed just the recovery first but I wasn't thinking....
Any suggestions on how to get root back? I read these forums quite a bit and I am thinking that I am SOL but hoping maybe someone has a suggestion I haven't seen yet.

Checking your flash counter in TA trips your counter, that's why it's at 1. Use mobile Odin to flash root66 to get rooted again.

Ok, thanks for the explanation on the counter. Don't I need root already to run mobile Odin?

Oh, duh! Yes lol you do. There would be no other way. Have you tried a factory reset then try to connect your phone? You could also try to install Kies on your PC to make sure all drivers are correctly installed.
If you wouldn't have said you have tried other cables, I would have for sure thought defective cable. Some cables are also charge only.

Yeah, did the factory reset along with all of the other suggestions I could find. I typically try to avoid Kies and since I cannot even get the device to enumerate I'm pretty sure it's not driver related.
I think my only hope would be getting root or twrp intalled via stock recovery or adb over wifi.
Thanks, I appreciate the help.

download Odin3 v1.85
Put your phone in download mode (vol down=menu=power then after the screen comes up press vol up
plug the phone usb to the computer,
run odin
the first box on the top left should have a colored highlight (the ID:COM )
if that pops up, your phone is 99% functioning correctly, and only problem is in your computer.
When trying do do a regulad usb transfer to the computer:
I have noticed, sometimes I have to connect, wait a bit (like maybe 2 minutes)
then disconnect the cable for about 15 sec then connect again, and it pops up after a minute
you could also try this:
open explorer on the computer(double click on my computer) and see if there is a t999 in your left pane. Sometimes the autorun function in the
computer gets farkled and it does not open automatically and you have to do it manually,
Good luck & Aloha !

Go to galaxys3root.com and follow his t.mobile root tutorial WORD FOR WORD. USE THE USB THE PHONE CAME WITH AND KILL SAMSUNG KIES. also run Odin before you connect the phone to Pc, should be no problem bruh once it took me a couple of hours making love to my comp before I got a colored com box. And use a windows PC Mac suxx for this kind of.

I've basically given up trying to get the usb port working... I am convinced this is a hardware issue. Nothing shows up in the device manager when I plug in the phone whether USB debugging is on/off or I am in normal mode or download mode. The phone will never bring up the MTP options in the notification bar either. Again this is with multiple cables on 2 different comps where it used to work just fine. I think whatever bad charge experience I had last week damaged the USB host controller on the phone.
I think what looks promising now is using adb over wifi(http://forum.xda-developers.com/showthread.php?p=26844535) along with root via adb(http://galaxys3root.com/galaxy-s3-root/how-to-root-u-s-canadian-dual-core-galaxy-s3-on-mac-osx/). I can't do this at work but I'll follow up tonight on what will hopefully be success in case this could help someone else out.
Edit: Ugh, some quick googling shows that I need either root or working USB to make adb over wifi work.

I don't think so.... the micro usb port is mounted on the main board and short of replacing that entire board it would be a ton of time/effort for something that I don't exactly think is the problem.

This happened to me, and it was from using different devices in the same port (with same cable). I switched ports and it worked. Might not work for you, but worth a mention - it really stumped me and I tried everything including restoring the OS to an earlier point.

Now that S3's are getting older, more people will be losing their functional USB ports. I found holding the phone vertically with steady even pressure on the plug was the trick to getting a solid connection on my flaky port, at least enough to get stock back (to send it back). That was the longest 15 minutes of my life (OK, not, but it was in the top 10, mostly because it was simultaneously nerve-wracking and insanely boring).
I tried de-soldering a usb port on a Galaxy S. Yeah.... To say it mildly, the way Samsung sets them up is booby-trapped. You can't get the existing silver solder hot enough to melt without toasting the board somehow. The boards are also wafer-thin and dimensional on both sides. Despite generally having a knack for fine tuning and detail work (thanks to estrogen or something), I felt like an ogre in a doll house. I definitely would suggest having all the (exactly) right tools in place before tackling it. Even then it might not be the port itself, but something between the actual port and the other components.
One other thing to note, Mobile Odin is an amazing tool, but it's even ***more crucial*** than regular Odin to get your ducks in a row before you flash. Know exactly what you are flashing what your next steps are, and what your results are supposed to be. One thing in particular: if you flash a stock ROM, it includes stock recovery, and you will lose root. make sure you've run Triangle Away before you flash stock (which won't trigger your counter, but anything else will).
I plan to keep the Triangle Away and Mobile Odin apk's ready on ExtSD to install, and a copy of a stock image (ROM) as well, from now on, on all my phones. You never know when that port is going to give up the ghost.

Just thought I'd add a couple things here. More times than not, when someone thinks their usb port on the phone is bad, it's actually just the cable. Even if the cable works on something else, or works to charge the phone. They ruin much, much, more easily than anyone wants to believe! Especially when you plug/unplug it as often as with a phone.
As for Mobile Odin, I fully agree! It's one of my favorite apps by far! But if you're going to keep stock firmware handy, which I highly recommend, you may as well keep the root66 version. Flash back with that, then run triangle away, then in SuperSU, choose full unroot. Then all you need is a factory reset. Making TA the last step makes for far fewer user mistakes.

[Q] USB Only Works When Turned Off (Charging)

Been trying to figure this out for the last few days, Google support has been too. I've tried the basics, different usb cord stock and not, factory reset going to stock, different kernels, different roms.
I can only get my nexus 7 2013 to charge when I go to bootloader, then to power off, then uplug the cord and plug back in fast. Once the device is on I get nothing when I plug the usb in, computer or AC. I used to be able to connect to PC no problem. I use the OTG cable a lot for HDDs and my camera, now nothing works. Tried USB debugging on and off and MTP.
I would just say the usb port broke somehow and go for an RMA but since it charges while it's off I feel like it's software related... If you guys have any suggestions I would really appreciate it.

If you've tried different kernels, roms, and I assume different a PC, USB ports, USB cable, then you've eliminated software as a possibility, as well as external hardware, I would do a backup, (unroot and flash back to stock and relock is applicable) then RMA it, you're only delaying the inevitable by waiting it could be some corruption in the emmc, or some other hardware fault that might act unreliably.

Is there a way I can put it to full stock, bootloader and recovery through just the device. Since I can't connect to PC. The only way I came across was through the toolkits.

Well, you can boot into a custom recovery I assume, so you can flash a rom from there (you can get zips from here), then you can root the device (needed for next step), that part is easy enough, the following is only theoretical, go into the OS, install that bootloader lock/unlock app, lock the bootloader, then unroot from within SuperSU (that last part I'm not sure of since you just relocked the bootloader, so not sure if it will work.) Of course even if all that did work, you will still have a custom recovery, so hopefully they won't see that, I believe there are apps which can install custom recoveries from within the OS, but I don't think they flash the stock one.
Maybe someone else more knowledgeable knows of a better/effective way and they will chime in and correct me, etc.

I do think this will work. I don't think flashing a recovery voids warranty if you aren't rooted and unlocked... Thank you for the help man. Wish it wasn't RMA but is what it is...

I just did another factory reset. This time with Elemental kernel, stock 4.4.2 from google. Probably the 4th time I've factory reset but first time with this kernel. All of a sudden I got ADB connected to PC, first time I've had any response from usb while tablet was up and running for 3 days. Might not have to RMA after all

I hope it stays fixed, sometimes problems caused by hardware can be intermittent. Keep testing it daily.

Twrp issue and can't even turn on phone

my device has been acting very funny since I finally wiped internal storage. Each time I boot into twrp it doesn't remember my preferences. acts like its the first time I've ever used it. Also, it wouldn't let me just reboot the phone. Usually had to pull the battery.
Well, now I can't get it to power on at all. tried several batteries and techniques with buttons and power cords. it's unresponsive. I cannot figure out why? my screen is blank but I hear my computer recognize the usb connection to a device. nothing shows in Odin
Was last running stockMM port from Paulpizz

Hey buddy. I've been reading that qhsusb_bulk is a hard brick, possible fried bootloader. But I guess if you can make this unbrick.img on to a sdcard it may work. I'm scratching my head on what files go into this unbrick.img and if I can make it myself. Any ideas

Install factory image without connecting to computer?

I have a Nexus 5X (LGH791 MODEL) which is having issues charging or connecting to a computer. It will charge slowly but will not connect to any computer that I try. Every time I get a USB error "USB Device Not Recognized. Device Descriptor Request Failed".
Is there any way to revert back to stock using the google factory images (or some other means) WITHOUT having to connect to a computer and use fastboot?
The device is currently rooted, has TWRP installed, and has the July 5 OTA update installed (was able to flash that part using Flashfire).
Thanks for any help, and apologies if I failed to explain any parts clearly!

With Flashfire you can flash factory images. For slow charging try another cable. Cheap cables do not fast charge some times.

I tried flashing the factory image with Flashfire but it only updated the system partition. It seemed to error when it tried to flash stock recovery. Also, it's not recommended to flash the modem or bootloader partitions using Flashfire. Even the app itself says not to do it.
Also, i have tried 4 different cables/outlet power supplies. The phone says it's charging rapidly, but i'm only showing about 260mah charging speed when checking it with an app like Ampere.

Before you flash anything, make sure your USB connector is free of compacted lint. I had the same problem with my N5X a few months ago, it would charge, but not rapidly, and it wouldn't recognize that it was connected to a computer. The problem turned out to be pocket lint that had become compacted at the bottom of the USB port, it was preventing the USB connector from making full contact with the USB cable. Take something non-conductive with a sharp point (the toothpick from a swiss army knife works) and gently dig around a bit in the bottom of the USB connector well.

Been there and checked that unfortunately. I even went so far as to take it to a repair shop and they replaced the USB c port completely. Still won't charge fast nor connect to my PC :/
