TWRP and USB-OTG - G2 Q&A, Help & Troubleshooting

Hi there,
So I did something really stupid and I wiped my phone while in recover mode trying to install a new ROM. And now I'm stuck with a useless phone that can only go into TWRP and Firmware Update Mode.
I've tried every method to unbrick my phone, and have a previous thread on this forum trying to get help (http://forum.xda-developers.com/showthread.php?p=48914581#post48914581), but nothing is working.
My question now is I'm running TWRP 6.3.2.2, If I buy a USB OTG cable and put my rom files on a USB thumbdrive, can I then install the rom from the usb? If so, where in the filesystem does this usb storage show up?

I believe only TWRP 2.6.3.4 can support OTG (I've been happy with it).
I think you may have to ADB push the files from PC over while in recovery (may need to look around).

loop boot quickly

Sorry for my English I will try to explain my problem.
After rooting everything was fine, but when I try to flash stock firmware somethings happen.First problem is that my PC cannot detect the phone with Odin and adb or mass storage I am 100% sure that the problem are not the drivers because I root that phone on the same PC before a week and of course I try everything on a another computer, but without success.
Download mode Odin cannot detect the phone! after many attempts to fix usb problem now the phone cannot boot , only in recovery (loop)after every start it's show recovery with message
Filesystems:
system: rfs
data: rfs
cashe: rfs
maybe system, data and cache files are erased I don't know.
recovery version is 0.1.3.b5
How can I flash stock firmware without PC. For example HTC devices can flash from SD card - Gold card, and PB99IMG.zip (I can't explain very well what I mean sorry)
Maybe the phone is usb bricked !
working..
recovery - only recovery
Download mode Volume Down + power off + camera ) - but cannot connect to PC and Odin.
not working
after flashing new costume ROM - the same thing - reboot to recovery
installed software on pc
android SDK,Kiesmini_1.0.0.10075_1,Samsung PC studio 1.5.1.10064_2,Drivers for spica on (Windows 7 x86)
really I cant find post like this !!! and sorry for my English
If you can go to download mode and phone is not detected, then you have bad drivers or bad usb in PC. Try another PC.
I have 3 pc and 2 cables and the same problem cannot detect. Can I flash new stock firmware without odin ?

Have you tried different USB ports, specifically one on the back of the PC?

Calm down. Did you read what I posted above? I said nothing about drivers. Have you tried other USB ports? Most people find the ports on the back of the CPU work the best, not ones on the front, or on a hub. It does make a difference.

[Q] TWRP - Accidently formatted Internal Storage - No OS installed!

Hi guys,
I am seriously in agony!
I am new to Android so I am not very well around with adb...
First thing first, I accidently wiped internal storage, my rom and everything....
now i am stuck in recovery (TWRP) and fastboot and want to know if there is anyway i can install a rom or send the rom file to my phone...
Right now my phone seems to be not recoginized by the computer.
Please where do i start? Really appreciate your help!
(hope we had an external hard drive - it wouldn't have been such a big deal..)
You are going to have to use fast boot to flash you system.IMG and boot.IMG into place. Use this guide found in the stickies above your post.

You don't necessarily have to flash back factory stock system image. You can send the rom file directly to the internal storage of the device by using ADB or ADB sideload while in TWRP.
Never tried it, but I see it in the TWRP menu ("external storage") - put your ROM file on a USB key and attach to the N7 with an OTG cable.
The above respondent's suggestion (adb) will also work too. Paradoxically, Windows seems to be the most difficult platform to get this done, especially Windows 8.

Update 3-25-2012
I tried this with an older version of TWRP (2.4.1.0) and it worked just fine. 8 GB USB uSD card in a card reader on an OTG cable - VFAT formatting, no other partitions present
cheers

Yup, this guy helped me out with my issue. Get a flash drive and get an OTG cable (you can get it here http://www.amazon.com/eForCity-Micr...=1364349138&sr=1-3&keywords=otg+cable+nexus+7 for a buck and a half, free shipping. Download cyanogenmod on it, then go to install from fastboot, then select install from external storage, and install the mod. VoilĂ .

[Q] Please help, TWRP, no OS, no Mount, Wiped my phone

Hello from south korea
I have a twrp 2.6.3.0 installed d802 G2 and I accidently wiped my internal sd card so my device only boot to twrp not OS.
I tried to mount but I can only find exclamation mark on device manager which means I cannot use adb, fastboot, adb sideload, flash recovery what so ever..
I've been searching xda forum for about 10 hours and still get no results. I formatted, wiped, factory resetted, tried to install superSU(but won't work)
I think i've tried basically everything I can try.
Any suggestions? please help.

pushed volume up button and plugged usb -> boot to twrp

This is not a solution. Even if he downloads the ROM, how is he going to transfer it to the phone when TWRP can't mount as USB storage?

Buy a usb otg cable and use a thumbdrive or better, get a microusb thumbdrive like this one:
http://t2.gstatic.com/images?q=tbn:ANd9GcT7zE663nePyE27qqA93qyLeZnQyFOWSuz4zbWwm2IdUna2lIDP2w&t=1
Place the image of whatever and mount it? Just a thought
Perhaps by connecting the cable mentioned above would allow you to get into download mode and then heading in this direction: http://forum.xda-developers.com/showthread.php?t=2471370

Do you have the UTG cable connected? Have you tried connecting it at different points of the process?
(Just throwing out ideas here....)
You could try PMing jkang (the OP) to ask him specifically what he did.

what's the difference between UTG & OTG Cable? if these are the same , yes, I test my OTG Cable on another device [SAMSUNG Note 2] and it's work...
I had the same problem over the weekend. I wiped my entire phone from twrp, and the usb mass storage from the otg cable was not working for any of my usb sticks. I had no way to put files onto my computer.
But, then I used twrp's android adb sideload and managed to get clearn rom xe 1.1 onto my device. Then I used twrp to install the clean rom onto my device.
Took me like 6 hours to fix it. Adb sideload might be a good option for you.
I'm in the same boat.
USB OTG doesn't connect though, I chose install in TWRP, but I don't see my USB drive.

I have tried a few but no support.

Unbrick S4 without USB

Hello,, I have a galaxy s4 running on Omega rom,, and my usb porn doesnt work,
I did a factory reset to find that ALL the apps crash on startup
If the usb porn was working I would have just flashed the stock firmware,, but any operation that needs USB is impossible
Can you please help me? Isnt there a solution?
** It's USB port , not USB porn **
What exactly do you mean by that?
1) Do you have USB cable connected to PC and your PC does not detect it?It could be a cable problem.Have you try a different one?
2) It could also be a driver problem.Do you have installed the correct drivers so your PC can detect your phone right?
Also if you had a custom rom flashed to your phone you can make it work again just by flashing it back using a custom recovery.Format system , data , boot and cache partitions and make a clean install of your rom.If you have not a custom recovery I am afraid you have to flash your phone through USB.
First of all, I would like to thank you for your help
Apologies for that mistake I'm still getting used to my new keyboard..
The USB port doesn't work meaning it neither charges nor connects to pc, because when it was charging, I smelled some plastic burning, could be a short circuit
And I don't have the Zip of the rom anymore on the phone, could it be possible to put an SD card and flash another one that is guarenteed to work?
And yes I have custom recovery

Yes just put a rom on your sd card and flash it.

Yes.If you have access to recovery you can just connect you sdcard to PC with an adapter and put the zip of your rom inside.Then put it but to your phone and flash it back.
You could also try to mount your sdcard to PC from your custom recovery and you put the zip of your choice inside.

LOOP

My x722 has a boot loop, and I had not enabled usb debugging on it, now or the pc does not recognize, there is some way to solve
I had that Problem, too!
But I got it back going!
First, try to get into twrp again and re-flash your Rom+ Gapps.
If you have any other working ROM on your internal memory, you better flash that one!
If both is not available, conneect your leeco via USB to another phone and there, activate Media Transfer! On the other phone, you should See your Lex722 and can now send Files to it. Just replace your Pc with another Android. For me, that worked to get it going after hard brick. Was not recognized by PC and booted only into fastboot. Data were formatted...
