looks like my connector moved a little bit so now it's hard to connect the cable to my phone, my question is: Will they check if i'm rooted or not if i will go and repair it? Or is there any other way?
Perhaps someone can make a picture of the phone connector from very close so i could see if it really moved? Thanks in advance.

Just put the stock rom back on, that will unroot you and return the phone, they cant really blame a software hack on a hardware issue They do use some common sense
Does anyone know of any USB Jig for galaxy tab to unbrick it?

Same question from me. I have the USB jig for the SG2 and wonder if it works and will reset the binary counter on the tab?
I have the Samsung TAB USB-adapter but I need an additional male USB-female micosub adapter to try the USB jig out, and before I do try to find one I wonder if someone has tried it?

Hey man, it's sad what happened to your tab, but it's getting annoying to see you make so many different posts revolving aroung the very same issue...
Just my thoughts dude...just ask how much is worth to repair it! Maybe the price is ok!!
Peace

Hey, well I would LOVE to have someone else repair it for me but I can't, I called samsung they wont take it because the unit is from USA, i can't send it to USA because I am not a US resident, I can't send it to Service Absolute (even using my own money) becuase they don't repair non-canadian units... So what can I do?
Flip it on Craigslist?
EDIT, nevermind, I misunderstood the question.
Great Question

I was reading this thread and I have been looking for the same answer for my Note 10.1 2014 edition. USB Jig without seeing the tech explanation and drawing upon my own technical experience clears some memory locations in flash binary that hold values for tracking flashing, maybe the boot loader and some other values. If I could see or find the tech manuals I might get a better understanding. However, this USB Jig is a technician tool of convenience and necessity to gain access and repair electronic equipment. Basically, it shuns or shorts across two pins in the USB with a load (resistors) so it isn't out of control short and manages the amount of juice or some electricity to clear those registers and reset the electronic device safely. The real technical question are all Samsung electronic circuits in phones and tablets access the same way, or is there a different pin configuration to be used, or a different sequence of steps to prep or follow up with, or almost finally can't work as the USB doesn't access the same parts of the electronic circuit. Lastly, if an experiment is done to just go ahead and use the USB Jig. Will it be a harmless attempt or will using the USB jig damage the circuits in the device? The last question is a show stopper, Dirty Harry type of question. Did you get an answer yet by experiment or by someone passing on the answer from their experience. Someone knows this answer and I am going to have it. This is how open source, crowd sourcing works.
BTW you question is valid one as now that Samsung Tablets are all on USB and people are going to continue to want to experiment with ROMS and modifications. So this answer will need to be answered in the near future. Samsung benefits from their products ability to be hacked and modified as this one of the consumer draws to buy. However, now Samsung is gaining more and more commercial success they may attempt to limit this activity. The downside for Samsung is that they end of having to respond to experiments gone bad, bad business for them. So hence their service attention to the flash binary "got ya trap and take a penalty, warranty voided", to limit those activities.

Hello everyone, I am very happy to be a part of this forum. I love my NT 16GB with CM7. It is awesome.
I have an old HP Mini 1000 netbook with a bad hard drive and no screen. My thought is to mount the tablet in the area where the screen was and use the keyboard/mouse/camera/speakers and periferals. I suppose I would have to cause the tablet to function as motherboard/screen and attach all devices through usb. It is probably more work than it is worth, but would be neat to see. Let me know what all you smart folks think.

with a fully functioning ( ota ? ) usb port, then YES.
Totally out of my knowledge base here, but I think I remember reading something about "USB hosting" needing to be enabled in order to use USB peripherals. The NC has this cracked, but I don't think anyone has figured this out for the NT yet.

Tell me what you know about the NC's usb port please. . And I remember too that the development person toiling away on the new kernel @Kurma30, said the port's got no power ( oh no ! ) and so you need a powered hub -or- custom wiring ( ? ? ? ) to get usb to first base. Hmm.

Hi ,
My galaxy S2 is have a problem .... whenever i connect it to a power out / computer the power supply starts fluctuating because of which i cannot use my usb port on my phone to charge so i take out the batter and charge it with an external charger.
Is there any way i can root my phone without connecting it to my computer ?
And one more thing is there anyway i can get my USB port to work ?
I bought this phone when i was in USA but after i shifted back to India this problem started occurring.
The service center people cannot repair or replace it as its the USA version and not the International version.Some parts of International version are not compatible with this US version according to the service center guys.They also said that its IC is short circuited but i think when IC is short circuited the phone does not give display but its working all fine.
Please help me with these 2 things -
1.Rooting my phone without connecting to PC
2.Getting my phones USB port back to work
I'm guessing your USB port has a problem check out this thread
in my case the phones not charging.....
The phone reboots when the charger is connected
The answer to your question is no. Unless I've completely overlooked something.
You will need a good usb port to be able to root the phone. There have been a couple of people who have reported that they successfully replaced their own usb port, and say it is relatively simple to do. It may take a while to get a replacement port, but since the part is small, shipping to India should not be prohibitive. Replacing your own usb port seems to be the only practical fix for your problem.

where can i find a working USB port ?
Google it. Not being rude but damn...
If you have a question about when the next CD by your favorite artist comes out, you google it right? When you need to know where to find which site has the best price on that CD you google it, right?
Use that same logic here. You need a part, google it.
Also, eBay has been known to have items people want to sell that anyone can bid on. Knowing you need it shipped overseas, it would be good to make sure the seller will ship it to your location before buying it.
(Searching these forums will present you with the answer as to which part you need to look for)

Hi there,
At 4pda, they are writing, that some PX5 units have troubles with WiFi/USB below 0°C.
It looks like my Witson unit (MX2 MCU, PX5, Android 8) suffers from exactly this problem. The last days we had warm temperature and USB and WiFi worked perfectly.
Now I went outside and the issues are back. It's 0°C now here!
Can anyone confirm this issue?
At 4PDA, they suggest a fix by adding a screw-whole + screw to better fix the proccessor unit:
https://4pda.ru/forum/index.php?s=&showtopic=883219&view=findpost&p=77467642
It looks like the processor unit is only fixed by 2 and not 3 screws and especially the two most outside pins, which are responsible for wifi and usb suffer from loosing contact with cold temperature.
I'm keen on trying to hardware fix. But I'd like to know if someone has experience with this?
Christian
Seems like a easy issue to check for and then apply if your unit has this issue. You might help others by testing the solution and posting result/images.

I now read the whole post in an ugly into german translated version.
The theory with the processor unit is not confirmed, the people over there discuss about powering issues for the usb ports, temperature-related problems etc. No finally confirmed fix seems availbale yet.
As my unit is less than two weeks old, I am claiming warranty. At least I purchased trough an UK dealer with paypal, so first I hope for a replacement.
If I don't make progress with that, I'll open the unit and look for the issue.
If someone elso would have a confirmed working fix, I'd try it.

There's another thread where a few of us have been researching this problem. The fix is posted HERE. There's no need to open the unit.
There's links in that thread to the 4pda forums where they explain what the issue is also. Long story short, it ends up being a manufacturing defect relating to the USB host controller. Newer versions of the board don't have this problem. But I can confirm the above fix does work like a charm, I've tested it several times.

Hi there, will comment in the thread you linked. I have running that fix with tasker already but still have partial drops of the host controller. I'm also working on a tasker task to switch WiFi on as soon as it gets off.

If anyone is still interested in a hardware fix, my KSP units have a 5-pin IC for USB current limiting and I found if the part is cooled, the USB will not turn on when it wakes up. I replaced one with a TPS2001DDBVT, same package and pinout but better specs. It passed the bench test. I haven't gotten around to installing the HU yet.
Update: I installed the unit with replaced ic, and it behaved differently, though not yet correctly.
It's worth noting, a Dasaita HU which has not exhibited the low-temperature wifi issue has the same USB hub chip, but a different (much larger) crystal attached.
I installed the newer usb hub chip as mentioned in the other thread. No more low temperature problems, however if I reboot the unit via software (with a rooted app), the wifi does not come on. One must reboot with the reset hole. Do not try this while driving.

Hello
Can you make a photo of crystal and send it here?
Dasaita change something in board design (usb hub for sure) and currently doesn't exhibit cold temp bug.
Info confirmed with my friend with new unit.
I have older unit (from September) with older usb hub and need to make an upgrade.

Thanks for the info and question, I will send a picture, I can also compare to an earlier model, that's much easier than trying to trace the current circuit.

Hi
I have the same problem on my Dasaita bought on september 2018!
which upgrade do you suggest? hardware or software?
the problem occurs only with the dab module connected to the cable with 2 usb, while the single USB cable, which I connected the 4G wi-fi router, always works.
If I will installed the hal9k ROM, could I fix the problem?
thanks

I'm going for HW repair. I've ordered GL852 sop28 from ALiexp (0,55+3,4USD shipping).
Dasaita knows about problem with GL850, but they proposed to replace chip by myself or to send them SOM board and wait till they resend it back. well, i'm definitelly not happy with their response.
I hope that replacing USB hub will solve at least one other problem - random unmounting usb drives and problems with copying files from usb to sd-card.

You need to open-up your HU to check. Also there is a thread on xda regardig WiFi/BT issues;

and I think that you can check a type of the hub with app USB HUB

Ok. I'm going to check the chip model.
I haven't problems with the Wi-Fi or BT.
when the temperature is low the DAB module connected to the double USB cable doesn't work, everything else are fine.
could I have your same problem?
I changed the gl850 ssop28 with the better version gl852g. Now I have no real problems anymore with my xrc unit. There is a software fix in hal9k 3.1.1 in the mod settings but it was only working when it was not to cold. I had in cold days allway to wait and reboot the system ...

No, it's not really easy, but without no skills before I did it. I just watch some desoldering and soldering videos and tried a bit with an littel another broken board with a ssop8 socket on it. I desoldered a lot and soldered a lot on it and then I change the chip on my mainboard.

I used a soldering iron beacuse I din't had a hot air station.
