Phone can't be found by PC - Mate 8 Q&A, Help & Troubleshooting

Hello! REALLY hoping I can find some help here! Tried everything! Really!
So the story is like so, I decided I wanted to root my phone and customize it a bit since I've previously owned an jailbroken iphone and really liked how I could change ANYTHING. BUT! I did not get far. My computer can not find my phone. Never connected my phone to my computer for other reasons than to charge, which still works, so never really noticed it. But yeah, charging works but other than that, nada. My phone model is the L29 version. 4gb ram etc.
Checklist:
Yes phone is unlocked.
Yes phone has usb debug on.
Yes phone is on MTP mode, yes I did enable/disable that tons of times since I heard it can help.
Yes I got the allow hisuite ADB or whatever it is called enabled.
Yes the phone does charge perfectly so there is some connection.
Yes I have installed all drivers, including hisuite. MTP packs, android studio with all extras.
Yes I have tried installing legacy hardware for multiple different MTP and android usb drivers.
What could it be?! I am going nuts by now, I don't even care that much about rooting anymore I just want the usb part to be working. (although yes I do still wanna root, will probably need more help then too).
Really thankful if anyone takes their time to help.
Best Regards, Dennis.

No one? Please.

Infuse won't connect to PC, help?

Yes, I have read other threads prior to posting this. My Samsung infuse WILL NOT connect to my PC to attempt to use GTG's unbrick to revert back to stock. I have tried the following:
1. Multiple USB cables
2. Install Kies
3. Install Kies Mini
4. Uninstall both versions of Kies
5. Install just sole Infuse drivers
6. Attempted multiple computers (2 Windows 64-bit machines, 1 Windows XP SP3)
7. Attempted to use in VMWARE
8. Performed factory reset
9. Used USBdeview to delete any association of the device with the computer
10. Select mass storage mode when prompted to connect to the PC. Also set it to automatically select this setting.
I have tried everything I can find on this form and on the internet, still no luck. My phone makes the noise that it is going to connect and does nothing. Doesn't show that the device is installing, doesn't ever show up under my computer, just sits there. When I pick mass storage on the ROM it goes back to the main screen. I am running GTG's infused ROM, attempting to take back to stock. I have tried Heimdall, I have tried GTG's back to stock methods, phone NEVER is picked up by the computer even in download mode. To say the least, I have tried this OVER AND OVER on multiple machines, within the past week, and I would like to just go out and run my infuse over with my car at this point. I do not believe I will ever be buying a Samsung device again. Can someone please help me before I go insane? Any recommendations would be greatly appreciate on attempting to get this POS to connect to the computer. I am on Windows 7 64-bit edition.
Since you are attempting to unbrick... Have you tried to do a factory reset from the ROM settings?
Just my 2¢

1. You might have a bad usb data CORD or one meant only for charging, not DATA. Edit..nvm..saw the first line.
2. Your phone's UBS port may be bad.
3. Are you able to connect via kies air?
Thank you for doing your research. The only thing that I can see that you're missing is that you didn't say you ran the program with admin access. And comon Cheezy.. be nice. This guy knows his stuff man..

Apologize for not posting, I ran Odin as Administrator, even tried XP Compatibility mode on both Windows 7 64-bit boxes. I installed Ubuntu, but doesn't appear that GTG's Back to stock is compatible with Wine, so couldn't resort to that option. I didn't recall if I had tried installing Kies mini with administrative rights or XP compatibility mode so I'm trying that now. Will report back. I'm thinking I could have a bad data cable that's just used for charging. Thing is, it worked when I originally rooted the phone from Stock, so I was wondering if it had something to do with the firmware for GTG's infused and Windows 7 64-bit. But, I see plenty of people able to get Odin to work on his build, so doesn't make sense to me. I did flash back to GTG's Infused 2.2.1, seems to have fixed some of the issues I was having with 2.2.3 (random freezing of the phone, system volume freezing and crashing when opening through Settings menu), random WIFI turning on/off. That seems to be all good now. Just wanted to figure this issue out.
No luck... But, Kies Air does work. Still doesn't fix the fact that I can't connect via USB to store back to factory. But, I think that both USB cables I have may be bad for data connection. They are the ones that came with the phone, and BOTH cables attempt to just charge the phone and not attempt to mount the external storage in Windows 7 64-bit. Debating whether or not I want to order another cable, thinking about upgrading devices since I'm eligible at this time. Any recommendations on a good upgrade from the Infuse??

If you're looking for a data cable, i got 2 off Ebay for $1 each. They worked. Search for mini usb DATA cable.
I've seen them go bad midcharge. If you had it plugged in, wiggle it, push slightly in each different direction gently. sew if you can get a brief response.
Re: new phone, galaxy note seems to be the hot device.
Sgs2 seems to be the fav by devs
I know you've said you've tried different cables, I had the same problem and it did turn out to be a cable issue. I tried 3 different types, and I ended up having to use one that I got directly from the local AT&T corporate store.

If you have an old Blackberry USB it will work. I use one for my Infuse . Or maybe a friend of yours has one you can try before you decide to buy one...
Just my 2¢
Thanks guys, will definitely give that a shot and buy a new cable. I'm pretty sure that's gotta be what the issue is. I wouldn't think that 3 different computers are bad with two different OS's. I will probably get one here in a few days. I plan on upgrading the device here soon. I bought it out of pocket retail about six or so months ago so I didn't have to renew my contract. I'm waiting to see what they release at the end of next month's conference before upgrading. Probably give a quad core a shot to see how they are
Well, new USB cable NOPE, Still no connection to the phone via USB.
Did you try the ports on the back of the comp?

Drivel,
While you are plugged in, try pushing the connection around a bit. See if there is any recognition. If there isn't, i think you may have a hardware issue.
If it was a hardware issue, the trick it's to get att to honor their warranty.
if you're running infused, the trick is how to get out back to stock or to brick it
The closet thing i can think of is to download download dman uckl2 rooted package via kies air or by phone. Dl the stock kernal. Flash the ROM, disable lagfix, then flash the stock kernel.
That's as close to stock as I can think off for you to take to the att store and have them check the usb hardware port
edti: no prob GoSooner.
thanks qkster^ Thanks button failed on me
Take this with a little tolerance from a noob.
I am trying to get my G friends In fuse to upgrade and can't get past the unregistered device.
Shes uses it for prime business and is going out for 2 days so I can't wipe the internal till she gets back but I'm up to the last 2 steps. After pulling the sd card it wanted to but still hung. Will wait till she gets back to wipe the memory clean.
Following long trails of solutions it looks to me for some steps for you to try.
Do a search on your comp and find all kies. Remove all.
Pull usb from comp and phone.
Hard reboot of phone,reboot comp.
Reload Kies mini
Open above, file drop down,load drivers.
plug in usb to comp.
phone usb to kies.
plug in usb. Go/no go?
No go pull phone sd card. Repeat all above. Go/no go.
No go? wipe internal memory.
Repeat /Go/nogo.
No go /Sledge Hammer cure.

Appreciate the help guys. It's weird because when I first had the phone it worked for me to root the phone. I think I'll just stick to Kies air if I need to back up or anything. I don't feel like going through the trouble of flashing/exchanging and then re-rooting the new phone. I'll just deal with it. With the new USB cord I did trying a Windows 7 64-bit and Windows XP.
I do want to say that I appreciate everyone's help.
Had to remove the site address cause I'm a noob and this info wouldn't post. But the below is the issue for me.
[14] On February 3, 2012, the update went live on Kies Mini.
Samsung Infuses with "Kernel 2.6.32.9" blocks Kies Mini from being able to update to Android 2.3.6 "Gingerbread". An over the air patch should be released by 2/8/2012 to fix this issue.[citation needed]-

Nexus S has no service or USB connection

I have a Sprint Nexus S 4G that I've recently rendered without service or USB connection as a result of a fastboot accident. I'm currently running ICS 4.0.3 (Dooderbutt-aosp-v-5 build), but have tried restoring multiple backups on CM7 to no avail. Wiping all user data in CWM doesn't fix it either. I have also tried flashing the LC1 radio zip with no results.
The way I see it, my two best courses of action would either be to try and return to a stock ROM so that I can send the device in under warranty or to continue to try to fix it myself, which has been less than successful so far. Every process I have found online to return to stock seems to end in fastboot oem lock, which won't do anything for me as my phone doesn't show up in fastboot devices, file explorer, or seem to be recognized by my computer in either Ubuntu or Win 7. I've tried connecting on my friends' computers with the same results. I've also tried using another USB cable. No dice.
Sorry if I missed something obvious before posting. I tried to do a lot of research online and have reached the end of what I know what to do. Any suggestions?
Bump.
After some more researching, it appears that there is no way to lock the bootloader except through USB connection with a computer. Does this mean I'm out of luck? Any suggestions as to how to solve this issue? Since my first post, I've flashed ICS 4.0.4 with no improvement on the above symptoms. Also, auto-rotation doesn't seem to work. My Baseband version in About is listed as Unknown. Does anyone have any clue? Replies would be greatly appreciated.
have you updated the android drivers on your computer? you wont be able to connect to fastboot without the drivers. you can get it here http://www.junefabrics.com/android/ do the free download(on your computer) then follow the on screen instructions.

I'm running Ubuntu, so from what I understand, I don't need any drivers. Prior to this fiasco, my computer recognized it as a storage device in the file system as well as a device in fastboot. It doesn't come up as either now.
I had a similar problem after I updated to ICS 4.0.3, what version of Ubuntu do you have, and does the device show up when you run lsusb?
Also, have you checked inside the usb connector to see if one of the pins is bent or damaged?
I'm running Ubuntu 11.10 and no, my Nexus doesn't show up in lsusb or anything else I seem to try. I have checked the pins in the connector of the phone and even bent them around a little bit, but I doubt that's the problem. Since it disappeared immediately after a bad flash, I'm fairly confident this is a software-induced error.
Ok, the only other thing I can think of is a bad kernel or baseband, but since you've tried several different roms, I don't think that's the problem (unless you put on one that's not for your model).
Sorry I can't be more helpful, hope you figure it out!
Thanks for your help anyway. To be clear, each rom has its own kernel and baseband, correct? Are those things I can flash independently of roms like the radio?
Found something, not sure if you've seen it already : http://forum.xda-developers.com/showthread.php?t=1077168
This bit is especially interesting :
"*If your having problems after the radio flash......go to dialer:
Type in *#*#72786#*#*, put your msl in, and let it re-provision"
For the usb not connecting, I had the same problem. After trying every computer in the house, I grabbed a can of compressed air for electronics and blew out my micro usb port on the phone itself. There was a small piece of lint in there that was causing the connection to not be made. It's worth a try.

I'm attempting to try this work around, but I can't seem to find my msl. I've tried putting in an incorrect code and checking alogcat for it as well as the terminal output of getprop. Neither of these give me the number. Sprint mentions using this code for resetting your phone in this tutorial, but I can't for the life of me find the part of their site that shows the msl.
This is exhausting. I really appreciate all your guys' help though. Thanks so much.
Unfortunately, I never figured out how to solve the problem. I took my phone into Sprint the other day and lucked out on the repair technician. He was messing around trying stuff and had a moment of realization when he booted into Clockworkmod. Even though I had voided my warranty, he still let me replace the phone for the $35 fee. I walked out with a brand new Photon 4G. I'm so happy, it's like Christmas in May!
To others who have this problem: sorry, but I don't know what to tell you! Mine was probably bricked. The MSL number didn't connect the phone and neither did anything else I tried. Best of luck to you.

Jiayu G3 Device not recognized Newb question

Hi,
I just received my phone, and have a couple of total newbie questions. I have never had an android phone, but, have an unlocked android tablet for my daughter. I unlocked it with info from this site. Awesome help!! I couldn`t have done it without you. Needed a new phone, and couldn`t afford the home prices or contracts for the iphones, galaxies, etc, so went for the Jiayu G3. Just started using mine, but and having problem getting windows 7 computer to recognize the device. The screen looks great and so far, it seems nice, but I am not a phone tech. I`m more of a desperate user, willing to learn and try...with direction from someone with experience.
Has anyone else had a problem with this phone being recognized, I guess as a mass storage device, and is there some solution that someone can help me with?
Also, wondering whether or not to unlock the phone, once the first problem is solved. I don`t know too much about the benefit of the unlock in this case. Can someone share info on that? I SAID I`m a newbie, sorry.
Is there any must have software that any of you more experienced users recommend for this phone?
Does ANYONE know where I can find info on it in English, so that I can figure out what I`m pressing?
Seriously....Thank you!

Are you still having problems connecting as mass storage as i just plugged mine into my sons windows 7 pc and it installed drivers straight away. Whe you connect to pc does usb connected not show on screen and a turn on usb storage button not appear. If not then when you plug in the cable swipe down from the top of the phone to see the notification area. One of the notifications should read Connected As USB Storage Touch for other usb options. Now yours might say media device or camera (ptp) just push that button and you should be taked to a screen with 3 choices, usb storage-media device-camera(ptp) select usb storage and if drivers do not start to install pull out cable and plug in again and hit connect as usb staorage and then OK. Hope this helps, I have mine rooted but I would not bother as there is going to be an Jelly Bean update released if you root you won't get the over the air update or might even fail and download and manual update. Phone works great just as it is.
hello all! if you have a problem driver download PDANET install it on the PC and connect your phone. install the drivers it must be!
here is that if some help ....

PC doesn't recognise drivers

A month now ive got this phone and very impressed that ill probably use it as my primary phone, however ive tried on 2 pc's and a laptop and after downloading the necessary drivers and trying to unlock the bootoader it just wont recognise that my phone is connected, ive followed instructions previously given by another user, why wont those pc's or the laptop i tried recognise the drivers?
Even to root the phone so i can get rid of the ads would be something but you probably need to unlock bootloader before you do that, any suggestions?
Are the OPO is fuctioning or it's in hard brick? Did you try on OS8 or OS7?
I recommend you to download the official Android SDK. It rarely causes any issues unlike allot of other driver packs.

of course it is mate i only have it 3/4 weeks it's perfect except Windows xp wont recognise the drivers, funnily enough my chromebook recognises the opo when i plug it in but it's far too difficult and time consuming to try doing commands on a chromebook.

i think ill actually do that next time im in an internet cafe as these driver packs dont seem to be worth a f**k to be honest and the full sdk might work.

Computer recognizes my Idol 3 but not my husband's Idol 3

I've searched forums, etc. for 2 hours and cannot find anything about 1 android device working fine while another is not, so I hope someone can help me. I have had my idol3 since January and have never had trouble with it being recognized on any computer or laptop. My husband got his idol3 a few weeks ago and no matter which cables I use (name brand or other), no matter which computer or laptop I use, it will not acknowledge that his idol3 is connected. I've made sure that his is set to use the USB is set to transfer file (MTP) and I've enabled developer status so I can turn USB debugging on. I've gone to "manage my devices" on my laptop and turned off the ability of the computer to save power by turning off the any of the USB Root hubs. I'm at a loss for what to try next. Any help is much appreciated. Thank you!!
Sounds like you have done everything possible up to this point.
Are both phones running the same ROM version? His phone is new? Any other issues with his phone?
