[Q] Help unroot Galaxy S3 Neo GT-I9301I - Galaxy S3 Neo Q&A, Help & Troubleshooting

Hey everybody,
two days ago I purchased a Samsung Galaxy S3 Neo GT-I9301I. (DBT Germany, no t-mobile branding)
I read that it supports USB OTG so I can use my phone to backup photos from my camera's memory card to a usb hard drive.
I did that before with an android acer tablet and that worked fine - but in the field a phone is even better when it comes to size.
Anyway, for testing I tried to get a FAT32 USB Stick 8GB to work on the SG S3 Neo and all I got was angry. It didn't work although I read on specification list that it has USB OTG support. OTG cable worked fine with the Acer tablet.
Ok, so I rooted the phone following this Tutorial primehowto.com/root-samsung-galaxy-s3-neo-gt-i9301i-easy-tutorial/. (Sorry but since I'm a new member I'm not allowed to post outside links.)
No problems with it.
With app "USB Host Check" I took care about android.hardware.usb.host.xml and handheld_core_hardware.xml. Now they both are enabled and shown in green.
"USB OTG Helper" for rooted devices should do the rest togehter with ES File Manager.
I even connected the stick via a powered USB hub because without external power the SG S3 Neo again didn't recognize the stick.
Then for a second it seemed to work but the USB stick connected and disconnected every two seconds over and over again.
After all these hours I think I'm just done with this phone.
I want to return it to the store where I purchased it.
BUT there is this system change counter and I wanted to know if anybody tried Triangle Away with the GT-I9301I to reset the counter?
In the rooting tutorial above it was said that "You can always regain it by following proper unroot process (for example, flash official firmware and then use triangle away)."
I found this tutorial theunlockr.com/2014/10/10/how-to-unroot-the-samsung-galaxy-s3-neo-plus/ about unrooting GT-I9301I but it doesn't reset the counter! :crying:
Or maybe I just forgot something? Please help me! Thanks!!
Alex

Where you read it supports otg. It can be fixed on kernel size. Problem.with USB otg is that it isnt outputing power to USB so it isnt powering on. You can buy other otg Cable that can give power to your USB untill we do hack on kernel.

Hi Rox,
thanks for your reply!
I read it here: inside-handy.de/handys/samsung-galaxy-s3-neo/daten
It's a German page put if you go down to USB port section you'll see a green check mark at USB-OTG.
The power problem was same with Acer Android tablet. But there I could manage it by connecting a powered USB hub with OTG cable to the tablet and then connecting an external hard drive PLUS a card reader to the USB hub. That worked. I could move files in all directions.
The thing is with the GT-I9301I that the external storage gets connected and disconnected every two seconds even with external power. That makes it unusable!
So what would you advise me to do? It can be fixed on kernel size?

Can you send me dmesg when that happens ?

Yes, sure. But unfortunately I don't know how to do that properly... Is "Dmesg Log Viewer" app the right choice?

It would be better to downlao dterminal emulator and do :
After you produce bug write in terminal:
Code:
su
dmesg > /sdcard/otg.txt
Then send me otg.txt from your storage

Thanks again Rox for your support!
Meanwhile I installed Triangle Away and its system analysis told me the counter is still on zero!
So I guess I'm going to flash back the stock firmware with Odin and get rid of all customized/modified settings.
At least that's what I read how to proceed unrooting in the article I already posted above.
I just don't want to spend so much time on enabling a feature that other devices have right out of the box.
Hopefully they take it back at the store without any further issues and I can look for a different, more suitable device for me.
Thank you Rox and the whole xda-developers forum! You guys are doing a great job!! :good:
Best, Alex

Other users reportrd that it is working with that extra supply Cable. Can you please send me dmesg for futher fixes ...

[Q] Micro USB port not working

hello,
mi micro USB is not working propperly right now, for some reason it doesn´t charges correctly, it seems a little... "loose"... im currentl running CM 9 2012/05/26
and when it plugg it in the computer and manage it to start charging, it wont allow me to acces it as a mass storage device, in fact the computer wouldn´t recognize it at all!, any help!?
try another cable, or connecting it to other port after rebooting (usb musnt be connected)
Swyped off my Amazing Defy using ICS
happened with me too, got its motherboard replaced
crap... I`m rooted... so no warranty...
maybe in some repair shop of cellphones the will be able to replace it?
but.. did yours charged at all?
bacause mine does charges when appropietly connected... its just that sometimes it wont nad it will not allow me to get to the mass storage...
If your phone just charge but can't access to masive storage, look in the device manager , if you have a MTP device, your micro ubs port is fine, just try to install some stock rom.
it´s just that some times it doesn´t charges and I need to slowly start trying to adjust the micro USB port so it can charge... that´s why I say that it seems to be a little loose...
As well it will only charge when plugged into my XboX 360 or the computer (and some other devices) but not when plugged into the Stock charger... :S

USB not working for flash
Hi everyone, I came with a similar issue.
The massive storage USB connection is not working for me, plus I can't flash a stock rom,
Currently I'm in MIUI for defy (and it's the only option I am able to install), I tried to wipe data cache to install cyanogenmod 7 from recovery but it's not working, it get stuck in the boot logo. I want to install cyanogenmod because it is fast than MIUI jelly bean.
My idea is to flash the device, but with the usb not working Im stuck,
any ideas to solve this? or should i go to have the usb repaired?

If after a boot in bootloader (power+vol-up) and connecting to PC via usb cable nothing appear onto PC display 3 possibilities exist.
1. Usb cable is broken.
2. Pc have no usb driver foryour device (but even in this case a error message appear)
3. Usb connector or circuitry fron Defy is broken.

Yes, is OK your method but is a little dangerous if you not cover the cleaned pins with some resin. More safe is to use a toothbrush soaked in isopropyl alcohol or 98% ethylalcohol to clean the soldered pins.

[Q] USB Port Charges but no sync/detection by PC.

hi guys, just to say that i read and have been reading for almost 2 weeks now on everything i could find and seems no one has been able to fix.
Some threads go on for 4 pages and then it turns out to be the cable etc which i found fustrating as surely should of have checked cable first before posting.
Anyhow, my usb stopped working randomly, it charges fine but doesnt connect to computer what so ever, as if i never plug it in. If i do plug in a OTG cable to the phone it says usb connected and then disappears.
What i've done so far after countless hours of reading.
- Replaced USB connector with new part
- Reflashed a stock rom with mobile Odin pro
- Flashed PURE Google Rom 4.3 pre rooted with TWRP,
- installed CWM Phillz touch revocovery over TWRP
- Tried phone on 3 different computers all with kies and drivers installed, no luck.
- Tried many different cables
- Tried other samsung phones with those cables on all pc's work fine.
- Updated kernel via odin
- Tried to boot without micro SD card inserted etc.
Is there anything else that i missed? Anything else you could suggest? maybe i put the wrong rom on? possibly a PIT error?
bear in mind phones warranty is VOID untill i can get the USB working again. or even maybe because i replaced the usb connector my self if they can tell i opened the phone then also void.

Thanks for the reply and sorry for the super late reply as I was doing donkey hours at work due to colleagues not turning up.
Eitherway, I tried that solution for me and that was also a no go. Mount unsuccessful for the error iirc.
Would it help to say that i used to connect my external hdd to the phone previously and used to do so with a OTG cable and when the phone didn't read my hdds because they were ntfs i used a program called stickmount pro and others, possibly could it be that those programs caused an error?
Also i have come to realize that my memory card has now been corrupted and I can't read some of the data on it while in the phone or while using an external card reader.
Could this possibly be anything to do with the PIT? As that's the only thing I think I havnt been able to do?

Do you have the usb drivers installed correctly? Or try another usb port/ cable.
IVE put the USB driver in the c drive along sid the KIES and still it says its (USB) not recognised. Is there something else i could use instead ,i didnt like kies anyway.I tried to get airdroid to work (ive had that for 3 years) but it doesnt handle software (my phone) 4.4.2 it only does 4.3. It says FORBIDEN.FAILED TO SEND MESSAGE on my PC.
Most likely you are using an outdated version of Kies. There are multiple versions of Kies, ensure that you install the latest version of Kies. Then open Kies and have it detect your phone. That is by far the easiest way to install the proper driver for your S5 model. After the driver is in place you can close Kies and never use it again. Or uninstall it if you wish.
Do not use an USB hub, connect directly to your phone. If you have ongoing issues, use a different USB cable and port. Ensure that you are using a data cable, not a charging (only) cable that has the data lines shorted. If your PC has USB driver issues in general, then you'll need to resolve those issues first or use a different PC.

KIES V3. The trouble is i cant find the USB i now it should be there in the notif panel but it is not, ive got developer options & usb debugging ticked but thats all, have i got to do anything else (hair pulling time) i dont think so?
1) Should i plug it in the mains or usb on the pc
2) Im using the cable that came with the S5 is that good enough.
3) The S5 sits on a cradle shall i take it of.
4) How do i tell data cable, not a charging (only) cable that has the data lines shorted
5) Ive tried 4 different USB software and it gives the message DEVICE DRIVER SOFTWARE WAS NOT SUCCESSFULLY INSTALLED every time
6) Ive done a reboot every time the drivers are put it

If you use Windows 8(.1) you have to disable driver signature verification to get the usb drivers installed. Here is a tut. https://learn.sparkfun.com/tutorial...abling-signed-driver-enforcement-on-windows-8.

You are juggling too many unnecessary variables. Try to simply that and don't skip checking any of the points.
I have no idea what you mean by plug it in the mains? And at least until you solve this you should not be using a cradle, hub or anything else. As I suggested earlier, connect the phone directly to your computer USB hub. And if you have ongoing problems, try a different cable, USB port or even PC.
Making an assumption that the cable that came with the phone is good enough is counter productive. It's not impossible that it may be damaged or have some problem. Borrow or buy another cable, to eliminate one more possible cause of your issue.
Retrace and double check each step. As soon as you make an assumption that it's not worth checking x step because it couldn't possibly be the cause, you are skipping a possible solution. Make sure that you are using the latest Odin, make sure that you installed it from windows administrator mode, connect directly to the PC's USB port, different cable, etc. If you are methodical, you'll resolve the problem.
Good luck

Have you activated developer oprions and usb debug?

If you haven't given AirDroid permissions to send SMS directly, "FORBIDEN.FAILED TO SEND MESSAGE" might appear. Change the permissions in phone's settings for a try

Unknown USB Device (Device Descriptor Request Failed)

Hello guys,
after trying everything I could imagine and find on the net, I still didn't get my PC to recognize my S6 edge plus.
Hopefully someone od you has got some more ideas.
The Problem:
Connected Phone shows "Unknown USB Device (Device Descriptor Request Failed)" in the device manager. No MTP connection and no ADB possible so far.
Done so far:
Samsung USB Mobile Drivers
Kies
Smart Switch (with reinstall of drivers)
6 different cables with 4 PCs (2 Win10, 1 Win7, 1 Linux)
USB-Debugging on / off
*#0808# switched through every mode
USB-Hub drivers
Factory Reset
More Info:
5 of the 6 cables are working just fine for data connection with my S3
There is no infobar tooltip to change USB mode at all, just telling me it's loading
In Download Mode the phone doesn't get recognized by Odin (with same cord and USB Port the S3 does)
In Stock Recovery Sideload Mode the Device does not show up in adb devices (with same cord and USB Port the S3 does)
Regards
up
I'm guessing you have downloaded and installed the Samsung drivers?
New Infos on this case:
Local tech support inspected the phone. They suspect the mainboard to be defective due to corrosion signs.
Of course the repair cost would be ridiculous.
I'm gonna repair it myself, but I'm not quite sure if it's really a faulty mainboard.
I rather think of changing the USB board first, because it's like a 10th of the mainboard and more likely to get wet if that's the reason for the damaged phone.
Any ideas??
Regards
You didn't mention if it charges via USB?
Im in the same situation..
charge via usb but is not able to recognize the phone in any computer (a lot of different cables with 3 PCs)
My unit was wet and i think that something is wrong for this reason.

Hi Cento50. Have You managed to get the phone to work? At first my phone was showing up in "This PC" on Win 10. but after trying Samsung usb drivers to get Odin3 working now it is the same as Yours. Shows in Device Manager as: Unknown USB Device (Device Descriptor Request Failed). A strange Conundrum.
Hello @Photobil2012 yes fix habe worked!
One little wire have replaced 2ohm resistor.
And have fix fast charger and data comunication with PC!
We i have repaced first one diode.
Phone a this time work complete.
First this problem i have connected one hard disk to otg cable with phone battery low!
My suggestion Please caution to use otg interface with high current if have low battery in the phone.
This cause high current drain and possibile burn diode and resistor.
Hi Cento50,
Alright! Thank you very much for the most timely reply and tech info on the successful fix. This is very good news to receive. I just replaced the battery so it is brand new and that works fine now. However, if it is necessary I can apply the same type of fix that you applied. Great work, and thanks again for your help.

[SM-P600] Many problems, for just an update

Hello everyone,
I own the samsung galaxy note 10.1 edition 2014 and for some years now I have not been able to use it properly. When I put the tablet to charge, I have a red cross on the battery. Following much research, no proposals have allowed to fix the problem. I notably changed the battery, the charging port as well as the cable and the charger (while all the original components seem to work).
On one of the forums, I read that changing the rom and updating it on lineage on android 7 could have solved the problem. It also suited me because many applications that I use every day no longer work on the tablet.
So I try to root the tablet but once again a problem arises, odin cannot find the tablet in download mode. So I look at the device manager and I see that indeed on the usb port there is registered device descriptor request failed. So I go back to the forums, I try again a multitude of soultions that do not work as installed, uninstalled, reinstalled the drivers. Make manipulations in windows. Change USB port, cable. Activate debug mode or not. I even put the old charging port back. Nothing to do I always have the same message.
I also thought to myself that it was because I can't choose MTP mode on the tablet, I tried to do some research, I couldn't find anything conclusive.
So I'm in dire straits, I'm waiting for my savior :crying:
Thank's in advance for answers
Sincerelly
Ps: My tablet is in kitkat version and I cannot switch it to the lolipop version because I have a message telling me that the tablet has been modified.
