[Q] MTP USB Device?

I thought I was doing great after uninstalling bloatware. However, when I tried to connect my Note 2 to my PC via USB I received the error that MTP USB Device driver could not be loaded. Apparently I must have uninstalled something on my Note 2 that is not allowing me to connect to the PC via USB. I have been searching for days, read many postings with the same problem, downloading various Driver apps to no avail. I even downloaded and installed Samsung Drivers which also did not work. I still can use my USB plug from NOTE 2 to my Flash Drive to get stuff transfered to/from Note2/PC.
It never ends. Fix one thing and then another pops up. LOL
What else can I say except - H-E-L-P.

What de-bloater tool did you use ?
Does it show the apps it uninstalled ?
By default any de-bloater should only delete apps from /system/app and
/data/app.
Have you considered starting over by flashing root injected stock Rom?

I did not use any de-bloater. I used Titanium Backup Pro (TBP) and have a complete list of all apks uninstalled.
In TBP under Backup/Restore all apks uninstalled are listed. Plus, I kept a list of all that I deleted.
No, I have not considered starting over by flashing root injected stock ROM. Thought about it, however, if I
do flash, I'm back to square one.
If I don't resolve this one problem, I will remain at this point until new OS comes out. I do have a work around for time being.
I do appreciate your help, time and concern. Thank you.
What really amazes me is that this problem is all over the Internet and I can't find a simple solution. I have Googled it,
been on here doing searches, reading postings, etc. I have even tried Driver Booster.

Sometimes we miss something small and obvious. Have you disabled USB debugging mode in Developer options?

Can you check your phone setting by dialing *#7284#?
Method 3 on the link below.

Tried this and again no success.
Method 3 – Ensure you have the right settings By default my phone was already set to the right settings for USB file transfers so I’ll assume most of these ship with the same configuration, hence why I have this as method 3. I found this on a forum and while it did not work for me, it seems a few other folks declared it a success.
1. Launch the phone key pad on your note and press *#7284# (don’t forget to start with that * symbol!) When you press the last pound sign (#) this will bring up an option that will allow you to change your USB connection settings (modem or PDA) – change it to PDA.
I did not get any option that allowed me to change the USB Connection settings when I entered *#7284#. So I dialed that number and got an error Unable to process request.
Tried new USB cable and it still tried to load/install device drivers but not successful. Same error MTP USB Device Failed.
Thanks again for trying to help. I do appreciate your help and time. Still looking for a resolution.

I am trying to find out if you have all the files and compare with my files to find out why I can access phone utility and you can't. Your issue may be the driver or files idk. Tbh, I am not an expert. Just another android enthusiast trying to help. I have Tweaked Rom so mine may be different. I have found 2 system files in TBU, Service Mode and MTP Application. Do you have them also? Does service mode work for you when you dial, for example, *#0011#?

SUCCESS-Thanks to Y-O-U!!!!

[Q] newbie in over his head

the phone is a sprint gnex.
i had twrp as recovery, and i was playing around with it, got distracted, and my 2 year old grabbed it and wiped everything. no OS, no recovery, no nothing.
i'm not even sure where to start. my newbie self is thinking maybe odin? i used adb once, is that where i should be looking?
i guess my question is where does one start when he has no OS. and i could sure use a link for wherever factory images, or tar files, or whatever, are reposed.
please help a brother out, and keep in mind i am in fact over my head. just trying to salvage this if possible. it is not an urgent thing, as i the device is merely used as a media device for my 2 year old.
my laptop is a windows 7 device. i've downloaded usb drivers for samsung, odin, and adb fastboot. they are sitting in my download folder as zip files. that is where i stand.

Don't worry you'll be fine.
If you can get into twrp, try just downloading a ROM and gapps zip on computer and using adb to push or sideload to device (Google "adb sideload ROM galaxy nexus...exact steps easy to find)
If you can't get into recovery, or just want to go back to complete stock and start from there, go here https://developers.google.com/android/nexus/images
Grab a package for sprint gnex(mysidspr, aka toroplus) and if u have adb&fastboot installed on computer(if not then Google "installing android SDK" and it will be top result, fastboot and adb come WITH the SDK when u install it)
Then you just unzip that factory img file, plug device into computer while in boot loader mode (hold power and both volume keys), open the folder created when u uncompressed factory IMG file, hold down shift and right click and choose "open command prompt". Enter "fastboot devices"(no quotes) in the command window to make sure device is recognized. Then just run "flash-all.exe" or "flash-all.bat" in command prompt and BE PATIENT AND LET IT FINISH EVERYTHING. After that device will be like brand new out of box.

thank you so much for responding. i will play around with this later, but it is a bit comforting to know that maybe i'm not doomed.
i cannot get into recovery, so yeah, i don't know what i'm doing.

Why can't you get into recovery?
Are you choosing recovery mode via the bootloader menu? I didn't think it was POSSIBLE to wipe recovery from within recovery.
Even if you can't, trust me, Doing a factory img restore, or using fastboot to flash custom recovery again is VERY easy. To get the SDK that has needed fastboot tools, go here http://developer.android.com/sdk/index.html#ExistingIDE
And grab the needed exe for your setup(windows 64 or 32bit). Make sure you are getting the "ADT bundle" it's what has needed platform tools. Then just run the exe and follow instructions.
Now u COULD also just Google search for Wugfresg toolkit, and download and use that. Its very easy to use as well. I just prefer to have adb and fastboot installed to my computer so that I can always be good to go. Plus I use Linux so Im not able to use Wugfresh, but knowing how to just use fastboot and adb also makes ya feel like a boss(even though is pretty simple lol)
Don't worry, there is hope, and it's not gonna be difficult. You'll be up again in no time.

because you said you didn't think it was possible to wipe recovery from recovery, i went into bootloader. you are correct. in my panic i overlooked it. i DO in fact still have twrp.
but there is nothing to restore or install. so once my phone charges, i'll give it a shot as you suggested. would you kindly check in later in case i need some more help?
thanks my friend for steering me in the correct direction.

Of course!
I'm always checking in these forums, and I use Tapatalk, and have actually grown fond of Tapatalk notifications, so I SHOULD get a notif if you post back or PM(though I prefer to keep in thread, that way someone else searching for answer to similar issue can find a helpful thread as well)
Yea it sounds like your little one got into twrp and most likely wiped all of /data and /system. Instead of just a regular factory reset which would have left your stuff like flashable zips and all still in /sdcard. That sucks! I've actually done that on accideHahaha
hile back(a mistake you only make once to wipe all of /data AND /system lol, even though can pretty easily be fixed)
Sounds like you could use adb sideload or push to get ROM/gapps zips back on the device, or just go with a total device factory restore, whichever you choose at this point should work just fine.
I'm not sure if there is a way to do this yet, but I've always wanted to put a pin code lock for TWRP. That way if my nephew ever did find his way into there when using my phone, he wouldn't be able to do any damage. If it's not a part of custom recovery yet (I haven't looked actually lol) it would be awesome if someone found a way to add that feature in. Could save a lot of us the hassle in cases like this! Hahaha
I'll check back in the morning and randomly tomorrow (some of the day I won't have a connection, I use Gnex strictly on WiFi) to see if you need any help/tips/clarifying of any steps needed. Once you do this restore process once, you'll be amazed at how easy it can be, and as long as you keep the files on your laptop, you'll be ready to go if you ever need to do it again.

success!
i had a great deal of trouble sorting the drivers....took quite a while to get the pc to recognize the device. then i got confused about a few things...stunner, i know, but was able to reflash a factory image with the wug toolkit. so i guess i took the cowardly way and didn't do the adb route.
anyway, i'm good to go. i am left with the initial problem that had me in recovery in the first place. i figured flashing a rom would solve it, but no. so i'm left thinking it is on the server side. at least i have something to work with now.
so thanks again. without your calming words i never would have gotten this going. i don't have the temperament to play around with my devices, i've learned.

That temperament is something that is gained. MOST of us have been in that "oh holy crap what do I do now?!?! Im not prepared for this!!" Moments (my first one was on my birthday back when I had DroidX2, and didn't have my own computer to restore it using RSDlite sbf flash.. I accidentally flashed something that didn't work, and was left with no OS stuck in bootloop with no way to get into the bootstrap recovery we had...was without device for 3 days until I could get to a coworkers laptop!! Lol!!!) But the stress goes WAY down after you've restored device once or twice and have the tools at the ready with basic understanding of the steps at least
And as for drivers, I apologize for not warning/informing about that. I forgot that you mentioned you had multiple driver packages downloaded and i was going to clarify which to use(on a Linux setup you don't need drivers and it been a while since I used windows for my device so drivers aren't usually on my mind lol) I think a lot of people use the PDAnet drivers. But if you are connected to internet and just put device in fastboot mode and connect to computer, I think it will automatically find and install the correct drivers needed for fastboot/adb access.(the toolkit can also be used to install correct drivers I believe)
And don't worry, I wouldn't call using toolkit the "cowardly way". SOME people detest/despise use of toolkit since they think it takes away from learning and understanding how to do it without a toolkit. But when you use a toolkit you usually see command prompt correct? (Or at least a setting so you can SEE what it is running as far as commands) so you get to see what its doing, which helps beginners start to grasp the concepts of what it is doing.
Trust me, if you can use the toolkit correctly, you can easily transfer that knowledge to just using fastboot or adb commands.
by the way, fastboot is what's used for factory image restore. ADB is for pushing/pulling files, taking logs, sideloading a ROM/gapps zip that isn't on device, taking/restoring adb backups of system and or data, things like that. Think of adb as the "taker and giver". And fastboot as the "img installer/booter"...imgs being anything from system img files, to data partition img files, boot.img(aka kernel), recovery.img, bootloader update img, radio imgs. Things like that
The reason the knowledge from using toolkit easily transfers over to using just straight up fastboot for example is because of how they word the choices and menus. You will see it says something like "use fastboot to flash new recovery img", which the fastboot command for that in command line equates to "fastboot flash recovery "NameOfRecoveryImage.img" "
(With no quotes of course, and replace "NameOf...." With the actual file name of the recovery.img you have downloaded, and you can rename the downloaded recovery img file to something easier to type out if you want to also)
Basic structure of using fastboot command would be as follows:
fastboot[space]command[space]partitioname[space]filetobeused
Which after used once or twice is very easy to grasp basic usage
So are you able to at least boot into OS now? Also, make sure if you are trying to flash a KitKat ROM, that you install the 2.7TWRP recovery, anything earlier won't work correctly for 4.4based ROMs.
Again, any trouble feel free to ask.
(And apologies for the long rambling posts lol)

yes. i am in the OS now.
what gave rise to my troubles in the first place is that i've moved my residence. all my devices recognize my new wifi, and proceed along their merry way.
my gnex is another story. it recognized my wifi, shows me as connected, but nothing at all can actually access the server. i tried factory reset, nothing. then i was going to install a new rom, figuring something was corrupted. then my 2 year old took over!
so i am in the OS, but still cannot access the server. so it must be on the server side i figure. not sure how to fix this, but when i have some time, i'll do some looking around. i am going to try to access a different wifi network later on to see if at least it is not my device.
again, thanks for your help my friend.

what security do you use on your router? if WEP try changing it. the gnex has issues sometimes with using WEP secured WiFi AP's
also, if using a 5ghz network, I can only get mine to connect to that on channel 153. there are only a certain number of 5ghz channels supported.
might also want to just try forgetting WiFi network and re add?(if it restored the access points by any means including Google backup/restore)
and make sure your router isn't rejecting the Mac address for some reason(and some people will suggest reboot of the router to see if that helps fix it, which I've seen fix many connection issues)

well, my device works beautifully....everywhere except in my house.:crying:
as much as drivers befuddle me, routers do even more so. it must be a router issue, right? my device connects to google elsewhere. and all my other devices connect to google here at home. maybe tomorrow i'll try the router's live chat to see if i can get some help.

what type of security are you using in the router setting? WPA? wep? none?
what model router are you using?
is device connecting to internet and just not Google servers?
is device connecting to router at all and just no internet access?(meaning when you are in WiFi settings, and choose network does it show obtaining IP address and then connected? or just never fully connect?)
I've had similar issues in past and might be able to help with some more details

The same thing happened to me right now, while I was installing CM13 in my Lenovo Zuk Z1. I took a backup from TWRP and copied the same to my pc. Then I wiped all the data from my phone using TWRP. Then I plugged in the Usb back to copy the downloaded files of CM13 to my phone but my pc is not showing the Internal Memory of my phone. I am so freaked out right now. I dont have an OS in my phone and I am unable to restore what I backed up. I am just stucked in TWRP. Guide me through to install CM 13 or atleast revert back to where I started. Any help is appreciated.

[Q] HTC One X Need to get data off phone that doesnt pass Boot Animation/Red Triangle

Hi,
I need to retrieve my 1) contacts, 2) Messages. If someone could help i would be really grateful and appreciative.
My HTC One X is standard with no mods (software/hardware).
Ive never updated firmware from 4.0.2 i believe.
Recently i downloaded a few programs from Play store.
I dont know if that was what caused the problems but i started getting problems with the apps closing/crashing.
Long story short spoke to O2 whom im with who were no help just wanted me to factory reset. Spoke to Dialaphone who said factory reset. And tried a couple times with HTC with the second time the girl advisor suddenly saying she will terminate calls while i was talking of options and hwen i stated i had done nothing wrong ie did not raise voice, did not say anything bad/derogatory etc and why she was doing that she cut the call off. I was understandably very angry, and i feel i will not be buying a HTC again with that kind of treatment.
As i couldnt get into play store due to crashing apps. I rang HTC. When i first rang HTC they said backup and do factory reset. I asked how they said use HTC SYnc Manager. Dl'ed and connected phone. No phone coming up. The phone at the time was again crashing all the apps now inc the android core something app.
I uninstalled the recent apps i had installed. Two sound meter apps, two lightmeter apps.
And i restarted phone. Phone then restarted but has to date not gone past the HTC bootup animation screen.
I have used soft reset by using power button. Recovery mode by way of pressing volume button and power button and then selecting recovery. When i do do recovery it shows its doing something and then i get a red triangle with an exclamation mark.
Please i need help to retrieve the data contacts and mesages on the phone. Asi never had problems with the phone before i didnt get round to making a backup. Normally i used to do this but have had a lot of other things going on and have become somewhat lazy.
Many thanks

Maybe you will not be able to restore anything on your phone because of the factory reset but maybe you will have working phone. Go in bootloader and after this connect the phone to a computer you must see fastboot USB download fastboot and adb extract it to c:\fastboot open cmd and type cd\ after this cd fastboot and run the command fastboot getvar version-main and post the result here

Hi Thant,
Thanks for the help. To clarify i have not done any type of factory reset and do need the data. I have done a Recovery which showed the red triangle with exclamation mark.
If i do bootloader thing as you have specificed will it flash over the data?
Please let me know.

Maybe you will not be able to restore anything on your phone because of the factory reset but maybe you will have working phone. Go in bootloader and after this connect the phone to a computer you must see fastboot USB download fastboot and adb extract it to c:\fastboot open cmd and type cd\ after this cd fastboot and run the command fastboot getvar version-main and post the result here

You must to go in bootloader and choice fastboot after this connect the phone to computer. Then you must download fastboot files and paste in c:\fastboot. Then run cmd and navigate to this folder and run the command fastboot devices and you must to your S/N. If you didmn't see the phone install latest HTC drivers and post the result from command fastboot getvar all and delete your S/N and IMEI from the info

Thats perfect. It worked. Thank you.
I Have attached an image with the results.

Download THIS and run as Administrator and fallow the instruction. To hope you will not lose any data because if you unlock your bootloader have big chance to wipe everything

Any news with the RUU?

I followed the instuctructions and the phoe rebooted and started working and booted into Android. But messages and contacts seem to have been erased in the process as nothing is showing.

Yeah that's what a ruu does, it deletes everything and put the phone back to factory stock

Yes but you have your pictures you must to use google acount for future to not lose your contacts. sorry but I say in my first post maybe you will not restore your data but you will have working phone. Sorry again for the contacts and for future use google account

For me the phone didnt matter but i needed the messages and contacts. My fault for not backing them up but they were all very important to me. If there was a glitch/hack that allowedrooting without wipe i think that would have been a way around it. Even HTC didnt want to help which i think is silly for situations where it is vitally important info and for fee as well not a freebie.
Thank you for your help anyways in getting the phone past bootloop.
Thanks

No way to restore contact or message from broken phone sorry. If you unlock the bootloader have big chance to lose your picture but with RUU you keep them and lose only data,system and cache partition on the phone

I have latest firmware and phone constantly restarts and more recently screen freezes. Mainly restarts all the time. Fed up of htc and their problems

Phone unaccessable after update(?) - systemui error

Phone M8 Europe, OS 6.12.401.4
problem:
phone is unaccessible - Error: com.android.systemui stopped working
This happens after he (is not sure tho...) had his phone updating. It was not reacting, so he restarted several times. Finaly he got "preparing apps" (not sure about the english term for it, its appears after you update before you) what amde he think there were an update.
Now after you start the phone the message "com.android.systemui stopped working" appears over the lockscreen. The lockscreen is still visible, clock shows and is not frozen also i can see the statusbar, Volume keys are working too. When i click ok on that message the lockscreen disappears, i sometimes get some screen flickering seeing a background picture (my friend does not know this). Touch inputs not accepted or nothing happens, same for volume keys but i can push power and choose to restart, airplane mode, shutdown and touch-choose this. If i understand that problem right, its related to the homescreen, so if i somehow can bypass this the apps and menus and stetting will work fine.
Now there can be 2 reasons for that. First something went wrong while updating and restarting and second a problem with the launcher (Smart Launcher) he installed on the phone because he had trouble accessing the statusbar.
Now i want to access the phone without factory reset because of all the important apps/data stored and not backed up...
I cannot access via adb - no device shown, i think because of usb debugging not enabled.
Delete the cache did not solve it. I cannot clear Dalvik, HTC Recovery does not show that option. Also installing TWRP is not possible because i cant unlock the phone.
When i install a stock rom its the same like factory reset, right?
HTC Sync Manager will not find the device either.
I am out of options, maybe you have some ideas? Is it possible to fix this without losing all the data? Are there other ways to access the phone like plug in a keyboard and use key combination to try to get into a menu?

Probably not. If the OS is not accessible, and the phone was not previously bootloader unlocked & TWRP, there is no way to retrieve the data.
You can run the RUU, which will probably repair whatever is wrong with the OS. But the RUU will wipe all data on the phone.
Either follow the instructions here, to run the RUU by htc_fastboot: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Or if you have an SD card, it may be easier to rename the RUU zip to 0P6BIMG.zip , put it on the SD card, insert in phone. Then restart to bootloader, and it should auto detect the zip and install it.

Don't know what you mean by "can't unlock the phone"
Does that mean you tried, but were not successful? If so, describe the exact steps you took, commands, and specific outputs, error messages, phone status that resulted, etc.
Probably bootloader unlock is perfectly possible, and you just aren't doing it 100% correct. Although the process to RUU is probably easier. Unless you also want to root, custom ROM, etc.
Also, unlocking the bootloader will wipe all data on the phone.

Thanks for your help redpoint73.
Apparently i did not properly read the "how to unlock/twrp", looks like i dont need to put the phone into usb debugging.... Nevertheless does the disclaimer on htcdev warn me about getting all user data deleted in the process :/
Biggest problem is to get the user data, but all solutions i found to get access to the phone involve clearing it. A factory reset will do the trick and she can use the phone again i guess, since the phone is not exactly bricked...more like softlocked. Everything seems to be running fine but the home/lock-screen. If that wont help i will run that RUU.
I will do some more research maybe i find some other solution to bypass it, if not i will we reset.
Also i dont understand how data can be so important that its a tragedy if its gone, but not important enough to backup. but thats not my problem.

There is no such thing. If the data is important to you (your friend, etc.), back it up. It's that simple.
There is a variety of ways to backup, and a number of tools were preinstalled on the phone. So there was really no reason for your friend to not be backing up.
Searching for ways to retrieve the data after something goes wrong, is not good plan. The likely result is going to be regret. But I guess some folks need to learn the hard way!

You don't need debugging for fastboot commands; you only need it for adb commands. While adb and fastboot are related, there are important differences. Fastboot (not adb) is what is needed to unlock the bootloader or RUU.

You were right, i was not able to save any data. The problem itself was solved with a reset - phone working again, top of the screen still not accessible, prob. broken.

mi a2 lite crashes and freezes since December 2019 pie update. (benchmark logs)

Hi
Since installing the December 2018 update to Android Pie last week my phone has become unusable. It freezes for 5-10s period all the time while using. Sometime, when it wakes back up again, there is a message on the lock screen that says 'you need to unlock using pattern after reboot' which makes me think the phone is crashing and rebooting itself while the screen stays frozen.
I have done a factory reset twice. In fact, directly after the December 2018 update, the phone got stuck in a boot loop and I had to factory reset then, as well.
Anyway I did some research on here and have run Androbench as people seem to be blaming poor write performance. See image.
Please - what can I do? Roll back to an earlier version of Android? The phone has worked perfectly for months until last week.
Many thanks.

you could try to reflash the latest pie rom with miflashtool. if you tick "flash all expect storage" you wont 't lose any data

download the latest rom from website, extract the image folder with contents inside and add this flashall.bat to the image folder contents, https://1drv.ms/u/s!AqlJY73bUA7rhokx5kWL6MAtXYDRTg . This will completely flash the whole phone without relocking the bootloader. I had exact same issue after using twrp to make a nand, its had something to do with accessing firmware while making backup, i think this will sort your phone out, dont use miflashtool its a total mess. Dont mess with flash order, ppl may say it doesnt matter what order its done, but it does matter. Instructions are, assuming you have adbtools, to use admin cmd prompt to the image folder and type flashall.bat, you need to add adb platformtools to windows system variables path.

Brilliant - thanks for the reply. What you suggest is probably on the limit of my skills and experience, so I have a few questions if that is OK:

Thanks, I will check that platform tools is in the system variables path. Maybe it will become clear, but I can't remember if the rom image needs to be stored on the phone or PC before I start?
Thanks

After fixing itself last time (with a factory reset), my phone's performance has gone absolutely again since the September update. It hangs constantly, takes 10 mins to turn on, and is generally unusable. Memory logs below.
This time nothing I have tried will fix it, I have tried: factory reset from bootloader, miflash to latest rom, using fastboot to flash latest rom, using the modified flash_all.bat from boe323 (thanks for your help last time).
Still the performance is dreadful.
Is there anything else I can try before I throw this phone away?
Thanks anyone for helping

Flash lastest stock (10.0.13.0) with no flash but use: fastboot oem edl , u can search in you tube how to do is easy

Hi, thanks for idea, I did this last night (new memory logs attached)
Still I get the same issues. system UI hangs and crashes basically make the device slow and unusable, especially in Chrome.
Any ideas on what I could do next?
Ideas gratefully received
Thanks

If nothing helps , just use MiFlash , and don't use clear all , use clear all_lock.Relock your bootloader and test if everything is working ok. If it doesn't - then I hope you have warranty. Relocking and unlocking the bootloader is so easy , so you don't have to be worried about nothing. Then you will be sure , if the problem presists with totally stock firnware , then you have only one choice.

thanks - trying this now

Downloaded your app and tested it on my perfectly working device. No problems at all, no hangs, fluid, etc.
I attached the results.
If you flashed stock ROM and the speeds are that horrible... you should check if any apps are causing the hangs. Reboot in SafeMode and check the speeds. If the phone behaves normally in SafeMode, than something you installed/configured is causing the said problems.
The last solution would be... checking the NAND chip, I don't quite know if there are apps that could check the sectors in the NAND memory. Maybe you are experiencing a bad nand/multiple bad sectors slowing down everything... But from my knowledge this shouldn't be a problem in current technology, since Android has auto-trim and bad sectors should be ignored, not affecting performance.
From my experience August update fixed the problems and September brought a system speed-up. I feel the phone even more snappy now.

Thank you for this. My phone is fine in Safe Mode! I didn't think of this, as when I was relfashing the Rom I wasn't installing any additional apps - just the Androbench to check performance (always after checking that the problem was happening).
So, what to do? Does this mean that one of the Stock ROM apps? is causing the issue? How to fix?
Many thanks for your help

Get an app like System Panel 2. Set it to monitor all apps/system activity and check where the hangs comes from. Maybe even AndroBench is the culprit in your case.
Anyway, get a system monitor app that can log all app activity individually and see which app has the most cpu usage and which app has the most disk usage.
But by the fact that your phone is running extremely slow after reflash, I suspect the back-up/restore system. Maybe it downloads some corrupt data and hangs the system. If that is the case, a new Google Account may fix the problem. Start fresh.

OMG I took the memory card out and everything is working fantastic again
