USB to PC: keeps disconnecting when accessing memory - Galaxy S II Q&A, Help & Troubleshooting

Hi mates,
since this evening, my Galaxy S2 (unbranded, unrooted, with stock firmware) was connecting fine with my PC in the "kies mode". I could use kies flawlessy, and I could regularly see my phone in my windows 7 (x86) explorer, and use explorer to read and write files from and to its memory.
Then, this evening, I got a notification, from kies, that an update (of kies) was available (2.0.2.11071.182.2), and I gave my consent to the updater. It did all its dirty job but after the installation of the new version, despite the phone connects via USB, every time I try to access the phone's memory from the PC, the connection drops. It restores backafer one second or two, but then again, if I try to access the phone's memory, it drops agains. The problem appears indifferently when accessing phone's memory from kies, and when doing it from windows' explorer, and this makes me suspect of the drivers, that the new version of kies brought along.
The phone connects correctly to the PC in the direct USB mode, and I can access its memory with no problem, and this also suggests that the problem should be the drivers.
So I uninstalled everything (new kies and drivers), and rebooted the PC, then I dowloaded what I believe is the previous version of kies: 2.0.1.11053.99.3, and launched its installation. After the end of the process, I rebooted the PC, just to be safe. According to the list of the installed software in my PC (in "Control Panel > Uninstall a program"), the drivers have rolled back, as expected, to version 1.3.2410.0 (before they were 1.4.something).
At the first connection of the phone to the PC after the reboot, I got notification from windows that the device installed correctly and it is ready to use (all the tree drivers are indeed reported as installed correctly)...
The point is that all this did not solve the problem at all, and USB connection still behaves exactly as badly as before.
I tried again uninstalling and reinstalling everything, also adding a manual clean up of the windows' registry from any entry related to "samsung", checking that the phone was not set in "USB debugging" mode, and disabling the antivirus, but despite everything appears to be fine, the phone regularly keeps on refusing to maintain USB connection alive everytime I try to access its memory.
What drives me mad is the fact that until this evening, everything was working flawlessly!
What else can I try????

I've just made a test on another PC running windows XP, with latest Kies 2.0.2.11071_128 installed. It's my office PC, and although I'm not 100% sure, I seem to remember that, until yesterday, my phone was connecting fine with it, and with that version of kies. But now, all of a sudden, I have the same problem also with this PC...
So, likely, it is a problem of the phone... the MTP application restarts everytime I try to access the phone from the PC, so... what can I try on the phone, to see if I can fix this annoying issue? I DON'T WANT TO FACTORY RESET MY PHONE, PLEASE!!!!
If any of you has any suggestion, I would be more than grateful...

I had the same problem the other day and I could not find a way to fix it, in the end I did a factory reset from Settings/Privacy and its ok now, just wiping cache did not fix it, factory reset was needed.

Dear Odia, thank you very much for replying and giving me a clue.
So... it appears that there's nothing else to do, is there? Buhahhaa!!! I want to cry!!!! I haven't made a backup and resetting the phone will be really painful... I'm already starting to feel the pain in my ass!!!
By chance, do you happen to know if I will have to buy again the apps I have already bought from the market? I have always kept both "Backup personal data" and "Automatic restore" ticked in "Settings>Privacy"... Could this be of any help?

You can always make a backup now before the reset and you will not have to buy paid apps again.

Yes but how can I backup my phone if kies will loose the connection with the phone as soon as it tries to access its memory?
Oh wait a moment, Perhaps I could use Kies air? Deos it allow to backup the phone? 'cause I can't test it now in my office, there's no wifi here...

From what I can tell, its the amount of the power that is supplied to the USB port itself that is the issue. I have the same problem when I put my i9100 on certain computers. Same thing happens to my WD MyPassport. Certain computers it works fine, and some it will power it for a bit, but once the device starts to draw too much current, it just disconnects.
This is why I try to do all my modding and flashing on a laptop, since, for me, they seem to be the most reliable in keeping devices powered up properly.

This is certainly a good point, but in my particular case, USB connection used to work up until yesterday with all the PCs I have (2 laptops and a desktop PC), whereas since yesterday, it works with none (with and without using the same USB ports). In addition if I use straight USB connection (hence not through the MTP app used by kies), it works fine.
Anyway what you have just mentioned is actually what scares me, because it would mean a hardware fault. But I'm crossing my fingers, hopefully it's (just) a software related issue and a factory reset will solve it. After all, straight connection works, so it would be really surprising if it were a hardware fault.
I will try resetting everything when I get home. Another "nice" busy evening to account to Samsung!
I guess if all samsung customers were honestly paid for every hour spent mending/fixing the issues of samsung products, the company would declare bankrupt in a matter of a few days!

Ok, I solved the issue with a drastic factory reset.
Thanks Odia for helping.
I spent 8 hours backing up and restoring everything included all the settings and personalisations. I went to bed at 3 am, eating only a quick sandwich in front of the bloody phone.
THANK YOU SAMSUNG, I wish to electrocute all your ****ing managers.
I hate when something in a device screws up all of a sudden and noboby knows why. It could happen again any time, and again I would have to spend hours mending a stupid phone instead of enjoying my life.
By the way, does anybody knows exactly what data is automatically backed up and restored on google servers by these functions?
"Settings>Privacy>Backup of personal data"
"Settings>Privacy>Automatic restore"
I always had both tiched, and I noticed that almost all the applications downloaded from the market that were installed on the phone, were automatically re-downloaded and restored on the phone at first boot after reset, but I'm not too shure I have understood what else was automatically restored.

I just read this thread for the first time, and was sympathetic to your issue when I started reading. I could see that there had been problems, but suggestions had been made and you seemed to be making good progress.
I was getting ready for offering advice and wishing you well with your problem.
Then suddenly you start to wish physical harm on Samsung employees.
Bye.

This is a simple solution try it and it will work for you the next time you face it most of the time it is a hardware issue i have been facing the same issue and nothing helped neither the factory reset nor the *#7284# procedure.
Take a pointy object like a pin or a paper and then clean your usb slot of the phone properly cuz most of the times usb pin points gets connected with each other due to the atmosphere and metal reaction. After that it will work like a charm for you. Before commenting anything negative i would appreciate if those who are facing this issue for a long time try this and then comment

Had the same problem, solved it by upgrading the phone software.
Setting > About Phone > Software update.
No need to afraid losing files. Hope that helps.

i faced the same problem on the GalaxyS sometime back. i did factory reset too. I got the same problem again. but i remembered it working on my LG TV so i did not go for factory reset. I went for re-install of samsung's USB driver for Windows. now it is working fine.
I fully agree that Samsung needs to be more responsible and responsive in resolving the such problems without causing data losses.

You could have saved a lot of hassle by installing a custom Rom and Kernel. I hate MTP mode! Mass storage mode is much better, I never had any problems with that....

Workaround - Power Management
This may be fixed, for now. However, in the future, there is a small workaround that you can use so that you're not required to wipe your phone every time this happens.
Here's what I do:
Since the device's connection is severed after the use of a certain amount of power, we can control the power management of the port that the device is connected to.
On WinXP:
Enter "Control Panel" > "System"
Click on "Hardware"
Click on "Device Manager"
Find the "Universal Serial Bus Controllers" section
Click the "+" next to that, and find the "USB Root Hub" that the device is connected to.
Right-click on the Hub, then select "Properties"
Click on the "Power Management" tab
Then, UNcheck the box that says "Allow the computer to turn off this device to save power."
This will prevent the connection from resetting. It's a quick workaround that works pretty well for me.
However, I ought to note that the changes should be undone after you're done with syncing the device, ESPECIALLY if you're on a laptop. Otherwise, you could risk a lot of battery/power usage within a short time, even if there is no device connected to that port.
Good luck, I hope this helps.
Cheers!

Please don't bail out because of that comment, i have been having this issue for a month and AT&T almost sold me another phone telling me it was the USB PORT.
I changed my phone setup dialing *#7284# and changed the UART to : PDA from Modem and same for USB (to PDA) modes. This helped get connected as before it would not even recognize the phone (computer would not do so).
I was am not sure if it is not the battery or charging circuitry, as others also reported, but my charging circuit is working fine and my battery charges 100% and last all day as normal. I can connect to the USB port and see my phone for a short while but it will suddenly disconnect.
But same as before it suddenly disconnects and will reconnect cycling continuously. I also believe it is the charge circuit because when it is charging, i hear the phone constanlty beeping from turning the schreen on/off. Same as when it is plugged into the usb port on computer.
Am tempted to buy a battery, but is can run the phone on the USB port without a battery in the phone. Problem continues without a battery...disconnecting and connecting to the computer.

I was plagued with this same problem, until I tried the above fix, and it works brilliantly! No more disconnects, great stuff.

It's pretty old topic but maybe someone has same issue and doesn't want to loose data. I had similar problem (couldn't connect to device, also couldn't install/uninstall any stuff because of no-space-available error).
I managed to download all pictures/documents via adb - worked pretty well. A sample command to retrieve all camera pictures:
adb pull /mnt/sdcard/DCIM

Touch Pro will not sync via USB...

Okay all. Usually I don't post and just lurk around here to find the answers to my issue. This time after reading 300 posts about Activesync and the TP my problem is still not resolved.
Up until last Friday I have been able to sync the TP with my computer running WinXP via the USB connection. I sync with my exchange server OTA but use the USB connection for file transfers. My computer won't recognize that the TP is even plugged into the USB now. It still charges, but doesn't do anything else. I've rebooted the machine and TP, reinstalled Activesync on computer, unchecked the "enable advanced network functionality" box, changed USB cords, verified that I have the correct three repllog.exe values in my notification queue, and even hard reset the TP. Still no luck. I would think that it's something to do with the computer except that I plugged my Mogul in to check and it synced instantly.
Does anyone have any more ideas why the TP would not be registering as connected? You all are amazing when it comes to stuff like this, so any help would be greatly appreciated.
Thanks in advance.
uninstall the Windows Mobile-based Device from the
network adapters section of Device manager on the PC.
control panel -> system -> hardware tab -> device manager button
restart pc and plug in the phone via usb and select active sync.
also the reason this may work in your case is i have had to do this for a friend.
windows installed the general rdnis driver however each device has a different
instance installed and thus the one device can have a corrupted driver yet the
other works perfect.
i see that u used another usb cable, cuz once it happened to me that the cable would charge but vista wouldn't recognize my TP "unrecognized USB device" , until i changed my usb cable!
Well I finally just went to a friend at the Sprint store and he swapped me for another TP. The new one works perfectly with the same setup that the other wouldn't. I can only guess that somehow the USB connection on my phone failed somehow. Just wanted to post this in case anyone else may have this issue in the future. Thanks for the responses.
This problem has happened on a friends, as well as just happening to mine (about 20 minutes ago). The usual fix which seems to clear it up:
1 - Hook up phone to computer
2 - On phone, start ICS (Internet Sharing in Start -> Programs)
3 - Select PC Connection "USB" and Network Connection of any type (if Sprint stock ROM, I recommend using "Sprint")
4 - Hit the "Connect" soft-key (bottom left)
If you've never used Internet Sharing on the phone, your computer should install some drivers... Once that is completed, click the Disconnect left soft-key on the phone. Now disconnect the cable from the computer.
Close out ICS or soft-reset the phone.
Once the phone is back up, plug it in - it should work.
I don't know what is getting reset in the phone, but unless I connect with ICS, then ActiveSync will not connect whether I soft-reset or not.
The same thing happened with my phone.... I took it to the Sprint store and they even tried a hard reset. It worked once after that then again it wouldn't sync. So they just replaced mine.... It was like you said.... some malfunction in the phone itself.
Hope HTC can figure out why this is happening.
Touch pro not sync
I can sync with my Vista Laptop and my friends xp machine but not to my xp desktop. I have tried many different cables. Each time I try something new, I toggle the "enable faster data synchronation box on USB to PC on try to sync then off then try to sync.
I have tried to delete all the usb drivers and rebooted to let the computer put in a new set.
I have tried to delete all the non running programs in my device manager using view hidden files.....
I have uninstalled active sync and then reinstalled it.
I have hard reset my phone a few times to no avail.
I went and bought a blue tooth adapter so I could sync using blue tooth and this computer does not do a good job of recognizing the adapter, but it did recognize it the first time but, could not pair the two. my blue tooth adapter is now coming up as a an unknown device
when i hook up the phone this is the message i get:
USB not Recognized,
One of the USB devices attached to this computer has malfunctioned, and windows does not recognize it. For assistance in solving this problem, click this message....
Any ideas?
Thanks,
Kent
MCW junior member THANKS....
thanks so much, this worked for me I could not sync my tasks or calendar, once I did what you said here I did get and Error Code 67..then cannot connect saying remote party has ended this connection...whatever that means...but anyway it proceeded to start automatically resynching and walla..all of sudden my tasks and calendar were on my computer ....first time I was ever on this forum ....I shall continue reading and learning here...so appreciate your help...I love my HTC Touch Pro and have just figured out how to connect to my big screen tv with only an MP3 or the like cable...works beautifully...except picture on tv is not the clearest...I will work on perfecting that next if it is possible...
Then I want to figure out how to get the phone connected to my computer screen, just like I did to my TV...then your phone acts as a controller...it's so cool!!

Ok I just found a solution for this, at least under Vista.
Click Start > Settings > Connections (tab)
Choose USB to PC
Once I removed the check mark next to "Enable advanced Network functionality" and clicked OK, my PC immediately saw my TP.
Hope this helps someone.
so what does the faster syc option do?
Ok so I searched the internet and found the advice to turn off the faster sync option on the phone.
After trying everything else I figured what the heck..
So it worked.
(btw windows adds a dif driver rather then the window-mobile baised device driver... )
So what does this option do? What does it point to being the problem on the computer?
Thanks,
HA>!

yeah i was having the same problem...my cpu would just recognize my phone as a mass storage device... Read your solution. And it worked... Damn i feel like a moron should have checked. Thanks!
I am having the same problem except the enable advanced network functionality option is checked and grayed out so it can't be unchecked.
I am running a 6.5 rom...
Any suggestions?
Solution solved
If you go to Settings->Connections->USB to PC and uncheck Enable faster data synchronization.
You will notice below that it will say "(Clear this check box if ActiveSync does not recognize the device)"
Once I did this it worked perfect.

Think of this step as telling your tp to quick boot/sync if nothing between the device and the reciving pc has changed (ie: hardware, software etc.
Enables faster syncing and quicker connection and authentication between pc and WM device. Reason for unchecking this to make it work?, by hard-reseting or changing specfic phone information you've reset specfic settings that are registerd with your pc.
i was having this problem with my sprint tp2 and tried it and worked. wish i would of learned if before reseting my computer and losing some windows i had open and the hard reset on my phone and losing all my contacts now i gotta go back to sprint store to get them again.
Works on the Touch2
I had this problem, which was driving me nuts especially as it was intermittent. I found Dashrender's advice and followed it except for turning off "Enable faster data synchronisation". Brilliant, works perfectly, thanks.
But what are HTC doing putting something in the software that fouls things up?
I knew i wasnt loosing my mind!
I have been workn on phones for a while. And have just been freakn about these same Issues Sony vio with 64bit vista. Thanks for all the tips. only took 6 hrs of pain to figure it out myself.
I have a similar problem now with my USB to PC . i have used this usb cable for many flashes but now when I plug it in, my computer doesnt recognize the usb device. also TV-Out pops up on my phone too. what is that all about? i dunno what to do
just found this thread searching for why my tp2 wouldn't sync. somehow under usb to pc i had it set to disk drive instead of active sync. checked it and works like a charm, can even see it in my computer now.

[Q] HTC HD2 HELP! Phone does not recognize USB

Today i plugged my phone to the usb cable and instead of getting the usual connection option screen... nothing... The phone charges but no Data transfer. Did hard reset, still nothing.. now im stuck with the old firmware... any help plz?
might be the cable that you're using. i used before a cable that is not the original and the same thing happened to me, i.e. pc cannot recognize device.
Try Settings-->Other-->USB To Pc-->UNCHECK (enable faster data sync) this should help...
cable : original came with the phone (used to work up until b4 yesterday) also tried another micro usb cable that came with me N900 but still nothing.
I did the un-check "enable faster sync" still nothing
Did soft reset, hard reset using volume keys, and factory reset from phone setting itself. still nothing.. the phone charges.. but no data transfer.. its something to do with the phone because i tried multiple PC's the phone doesn't bring up the connection type option page

No harm in checking.Infact i faced similar issue once and the USB2 was disabled.It took me an entire week to diagnose the problem.These PCs have got a mind of their own and do mischievous things on their own without our knowledge.
But since its not working on multiple PCs,i am not sure.We'll hav 2 wait 4 a solution i guess...
hmmmm.. would a full system format and re-install be possible? and would it fix it? (talking bout on the phone)
HELP, HELP
SAME PROBLEM WITH HTC2 T0MOBILE
even on the boot loader screen, it charges but no USB stuck on serial.
even when on sleep mode and plug the cable orange led is on but it didn't wake up for choose (active syn or stoeag memory)
PLEASE HELP
i can do nothing, HSPL or rom upgrade
the cable and the USB drivers are tested more than 100 times
Most horror problems I had with the USB sync have been down to not having the latest version fo Activesync from microsoft. Uninstall the old version thwen reboot - now download the 4.5 version which I think is the newest and last version they made (unless im out of date) and then reboot the machine, then connect up the phone - but not immediately after the machine has booted wait a couple on mins, Windows takes longer than it often appears to be ready to go. One your hard drive led flashing light has settled down it is probably time to try. Then see if it finds all the devices in your phone.
If it doesnt go into the control panel and double click system, hardware tab, then select device manager and see if there are any devices with a yellow sign with a "!" in them. If there are delete them and then unplug the phone and plug it back in again. It might get past some stuck things. If it doesnt see anything new on device manager theres a menu at the top and look for "scan for hardware changes" this gives teh device manager another look at what its got connected.
If that fails open up the USB section under in device manager - its got a little plus next to it, press that plus and it open up all the names of chips you have for your USB control on the pc's motherboard. Write down the numbers and go and get the correct up to date drivers for that type of USB and install them. Then try the process again. Sometimes deleting the USB drivers and just doing a "scan for hardware changes" again, will reset the USB drivers and start things working, however it can get tricky if your using USB mouse and Keyboard to select anything if you delete the USB, because thats what the KM/mouse relies on to control teh machine, so have a PS2 mouse plugged in if you can. If that fails I would suggest reinstalling windows as its probably knackered. It amazing how things start to work wonderfully on a fresh copy of windows.
I have been where you are! And tried every suggestion that was given here. It all came down to the cord. I actually went through 3 different cords before I found one that worked and found that by accident. I bought an external drive and that cord works. For whatever reason, that is the only cord that now works for me. I only use it for data transfers. i use the other cords for charging.

USB Problems.

Hi guys,
So it looks like my USB socket is on the way out. It'll charge the phone fine when its connected to any mains power adaptor, but wont charge at all when connected to PC, nor will it appear as a device on the PC. I've tried several known to be working USB leads, and a couple of PC's but its no-go on any of them.
Before I go ahead and take it in to be repaired, is there any chance it might be a software problem, seeing as its still charging fine from a main lead?
How would I go about backing up my stuff (given that I cant plug it into a PC) and my data (have contacts synced with Google, not sure if there's anything else that I might want to save) and completely resetting the phone to a stock state? I may as well give it a go, and see if that fixes it before sending it for repairs, yes?
Is there any need to backup my apps in Titanium Backup before it is fully reset, given that I can just download them from Google Market again?
Its my first Android phone so I'm not entirely certain of the process involved. If it makes any difference, the phone is rooted, and using XWKL1 "Frankenstein" from the Intratech thread.
Thanks for any help you can provide.

PCs will turn off USB powering on excess current. An external power adapter however is identified as such since it has a short between the USB data lines D+ and D-. These two data lines are not shorted on a PC (of course ) as they are required for data transfer.
It is not absolutely necessary to backup Apps but you should definitely backup App data! This is best done with Titanium Backup backing up to your external SD card.
One more tip: before taking the phone to be repaired, make sure you reinstall a stock ROM and reset the custom ROM counter by using a USB Jig.
I was recommended one hack - doesn't seem to have worked for the majority from what I've seen, but it's worth a try - you've nothing to lose.
Post #5 here.
did u try connecting the phone as mass storage and see if it shows up on the pc? You can go to mass storage mode by going to settings --> Wireless and network --> usb utilities --> connect storage to pc. You need to click that and then connect the usb cable. Also after connecting it check in device manager if the phone is showing up in usb.
Seems as though the s2 has a really bad USB connector as mine has stopped working other than charging via Mains and more and more people are having the same issue. Samsung should really address this.

Also good to try is uninstalling KIES (make sure the drivers are uninstalled too) and then reinstalling. Plug your phone in AFTER the installation. If it still doesn't work, there is an option in kies somewhere to install the drivers again.
Hope this helps

Deleted System Files, Have Flashing Favorites Screen or Stuck in Orange Logo Loop

Well, I wrote a very thorough post explaining my situation, and when I tried to post it I was informed I was trying to register for my forum account instead. *facepalm* So with that thirty minutes wasted, let's try this again.
I have a Kindle Fire HDX 7. Software 4.5.2. I rooted it with an exploit, deleted some Metrics system files, and then after rebooting came up to a broken "desktop." The main Favorites window flashes from white to gray at me, there are no icons in it. I can't run any apps. I can get to the Settings menu, enable ADB, MTP, etc., but I can't turn on Wi-Fi or do updates. I did a Factory Reset, but that just erased all my content. If I reboot from this situation, I get stuck at the orange animated logo screen forever. If I hold the Volume + button and choose Factory Default from there, I can get back to the flashing Favorites desktop window, but still can't do anything just as before.
I have installed the Android SDK for Windows, installed the adb_usb.ini files, and the device is not recognized by Windows at all. It charges, but that's it. I tried using Ubuntu and SoupKit. They also don't see the Kindle as being there. No matter how many times I reboot the Kindle, all the SoupKit commands just hang at "Waiting for Device".
I made a Factory Cable. When I plug it in, the Kindle doesn't turn on. Holding down the power button does nothing. If I plug back in a regular USB, it turns right on. If I plug the Factory Cable in at the Flashing favorites screen, I hear the "plugged in" chime and the charging icon appears on the battery, but nothing else happens. If I try to reboot from there, with the Factory Cable still in, it shuts down but won't restart. I am open to the possibility I messed up the cable, but continuity seems good with my meter from both ends of the cable and from the solder joints to the micro-USB end, etc.
Has anyone seen the flashing desktop behavior? What should I be doing to try to get my Kindle recognized, so I can push the stock firmware back to it to fix this? Any help would be greatly appreciated. I made a foolish mistake and I can't seem to correct it myself, so I'm hoping someone else out there has the answer I'm overlooking. Thank you for your time.
Make sure you have the Kindle Fire ADB drivers installed.

I had already installed the Google USB driver using the SDK Manager, and also modified adb_usb.ini and so forth, to no effect. I tried the instructions at the above link, though, since that Add-On site was something new. It appears some things have changed since that article was written, though, since the only thing available from the Add-On site from Amazon now is just the Kindle USB driver. I installed it, but Windows still doesn't recognize the Kindle. I rebooted the computer and the Kindle just to be sure.
To be clear, when I say it doesn't recognize it, I mean it doesn't even appear in Device Manager as an unknown device. No matter which computer, USB port, or cable I use, Windows 7 and Ubuntu simply do not see a device as there. The Kindle chimes and shows the charging icon, but Windows doesn't see anything as being plugged in.
From what I'm reading, it appears the factory cable I made is useless with the Fire HDX line.
I notice that the SuperSU app is still installed for what it's worth. I can't run anything, so it's kind of hopeless. I can't seem to find the original exploit that I used, but I basically just tapped a button that said "Gimme Root" and then I had super user access. Dangerous, dangerous super user access.
I'm not opposed to opening the Kindle up and tinkering with things, if there's any chance that will help correct this problem.

"Factory cables" (sometimes called fastboot cable) are useless on all HDX models. Stick with a standard, high quality USB cable. I realize this seems counter intuitive but Amazon has done their best to make the latest generation of devices inaccessible to those looking to leverage the hardware or simply recover and non-functioning device.
Your issue with 'seeing the device' is likely due to Windows drivers. If the suggestion from @EncryptedCurse doesn't work suggest deleting all related entries from device manager when the device is tethered, reboot and then reconnect. Windows should install the correct drivers assuming you downloaded the Kindle specific ones in advance. There are shortcuts to this procedure (eg: a reboot really isn't necessary) if you know your way around Windows.

I plugged the Kindle in (I'm at the Settings menu on it, since staying at the launcher/home/favorites screen just threatens to give me epilepsy with its constant flashing), I removed all the USB host controllers and root hubs, then scanned for hardware changes to reinstall them. The Kindle is not found, as a recognized device or an unknown one. As I said, when I boot from a thumb drive into Ubuntu, it doesn't find it either. When I run adb devices, it says no device is found. I have heard of people getting it to take ADB commands anyway, despite the not found error, by just repeatedly rebooting the Kindle, but it hasn't worked for me.

My bad - I overlooked some key details in your original post even though clearly stated. If you are not seeing the the device from any host (and you have certainly done the things I would have suggested) there is little you can do to recover via standard methods. A couple longshot suggestions:
- change cables. I know you tried a homebuilt cable but grab a couple standard cables just to rule out a bad wire; crappy usb cables are more common than people think
- check for a bent/missing pin in the micro-usb port; possible you aren't making a data connection (for others benefit, data and charge use different pins)
I realize both the above are highly unlikely given the sequence of events that lead up to your current problem. Running out of ideas ...
I doubt this will help, but one long shot on Windows is try to use the HDX toolkit to install the adv drivers. It won't do anything else with this build, but if this is a driver issue, it could possibly fix it. Also, if you can try revoking adb permissions if you can get to that window and try a different usb port.
These are all last ditch efforts though.
I tried the HDXToolkit driver install. It seemed promising, but it still doesn't see the Kindle. Checking the connector to see if the data pins were damaged was a good idea, but unfortunately they look unmangled. I am using a regular USB cable at this point, by the way.
I can't disable ADB mode on the Kindle itself. I can go to the Developer menu and try to disable it, but it just kicks me back to Settings and the option stays set to On when I go back to it. I can switch between MTP and CTP for whatever that's worth.
I appreciate the optimism. I'm quite upset with myself for doing this to my Kindle, as I really was getting a lot of use out of it. I can't help but be a little mad at Amazon, too, for making it so hard to fix this.
Oh, I was also going to mention that when I go to the stock recovery window with the option between reboot and factory restore, at the bottom under the Kindle logo it says "No Command" not sure what the significance is of that. I've seen where some people get a lot of error messages in that area.

Some very left-field ideas:
- try enabling bluetooth. Obviously if you can get that working there is a way to move files to/from device which might provide additional repair/recovery options.
- there is a rumor that long pressing power (40+ sec) performs some type of 'hard reset' on the device. Never see it work but worth a try.
If the device is still within warranty reach out to Amazon. They are pretty good about providing replacements (say it died during an update) although it will likely be a refurb. Who knows, might get one with a low enough fimware level to unlock. That opens a entirely new set of options.
It would appear that the HDX can't use Bluetooth for file transfers, only for connecting peripherals like keyboards and speakers. I'm going to try it anyway.
I have done the long power button hold down, but it doesn't seem to do anything.
I believe I should be in warranty. I got my Kindle for Christmas, so it's only about 6 months old. I'd rather not have to lie to customer service, though. So I'm still prodding at this trying to find a solution. If I could just get WiFi to work, so I could download a firmware update, I think that might help, but of course everytime I put in my network information and tell it to save it, it kicks me back to the Settings window and I get no connection.
The 40 second Hard Reset never worked in my case, although My Kindle didn't even boot up after my stupidity.

Understand the ethical concern. Stating it died during an update is technically correct provided you don't indicate who was doing the updating. If asked if the device is rooted then you should come clean (which could impact Amazon's decision whether to replace). I have a great relationship with Amazon and believe honesty will ultimately get you further than deception.
So it doesn't appear there is anything else I can do about this. The Kindle isn't recognized by any computer I have, using Windows XP or 7, or using Ubuntu. I read that XP might be able to see it if I disabled ADB, but it's permanently turned on and if I try to turn it off it kicks me back to the Settings menu without actually changing the setting. Since no computer can see it, I don't think there is anything I can do to recover it. Unless someone figures out a way to flash the ROM by taking the thing apart and doing it manually, which I don't think is going to happen anytime soon. I can't believe I ruined my Kindle. Looks like all that's left is contacting support and seeing if they'll help me with a replacement.
Actually, one other thing. If I have to send the old one back, won't they notice that SuperSU is installed and realize what I did?

Sorry for your troubles. Amazon is pretty easy going - at least in my region. If the device is in warranty and you simply describe the symptoms without going into too much detail you should get a replacement. I don't believe they inspect devices beyond looking for obvious physical damage. The device will likely get 'reprogrammed' and be sold as a refurb. It makes little economic sense to have a tech inspect returned devices unless they are looking for something specific or a pattern of failures. Good luck.
Any have file APQ8074.hex and 8074_msimage.mbn for unbrick QHUSB?

[HELP] Samsung Galaxy J5 stuck in safemode, RFP locked.

Hello to all genius mind.
I am writing here, to find a solution for my problem. I will start from beginning, to be as clear as possible.
This summer, during my vacation time, while diving, I found SG J5 in the bottom of the lake (sorry for the person who lost it like that...). Since I never had android smartphone in my hands before, I was wondering, can this device still work, since I have no idea how long it was under water and what can I learn from this process.
After opening it up, cleaning with 96% alcohol and drying it, devices finally showed some signs of life. Actually, almost everything was working, amazing...
Once I got this device running, I started to deal with software. Following some tutorials online, I was on the process to bypass RFP, but could not finish it, since I had other important matter to attend to. After I was back, and turned device on, for some reason, it booted into safe mode. I have been tried again SideSync method, but it was not working, since device did not reacted, after I plugged in to PC. Computer can recognize device and I can even browser the files in it. Weird thing is, that lower volume button stopped responding (I had theory that it could be jammed, once I removed it and cleaned contact, no changes was in the system, still in safe mode, so its not jammed button...), it was working before and all other buttons are working fine. Because of that, I cannot load recovery mode.
OTG method also did not worked, since nothing happen when I plunged usb into phone (safe mode block all external apps). I have tried to flash new ROM, with a help of "Samsung 300K Tool" I can launch download mode, but new ROM did not gave any result either, and RFP blocks all custom ROM's, that could modify system.
ADB do not find the device, since USB Debugging is probably off, and I don't know a way how to activate it from PC. The trick to disconnect WiFi, when it checks info for google account, did not worked either, since its not possible to select a text for sharing it.
After trying all the methods that I could find, I hit the brick wall. Phone works fine, but its completely locked. I am thinking, that new Samsung protection system is designed like this, to force phone in to safe mode after one hard reset and lock all posiblities to byass RFP, not sure though, it could be hardware problem to, but no idea where...
Does anyone here could help me out with this case
THANKS!
Best regards to all,
HG
