[Q] Touchscreen doesn't respond after using bogus photo recovery software - Galaxy Grand Prime Q&A, Help & Troubleshooting

Hello, ladies and lads!
Here's a short version of where I'm at: after installing Wondershare' s dr.phone Recovery on my mom's PC and using it on her phone:
its screen won't respond to touch (can't enter SIM card's PIN nor open screen lock)
the On/Off button won't turn off the phone on long press (maybe due to screen lock)
on restart there's a yellow text that reads "Set Warranty Bit : kernel"
the physical buttons still work
I can see the phone's files and folders only through PC's command prompt, using ADB ('This PC\Galaxy Grand Prime' folder in Win Explorer says it's empty).
Ideally I want to keep her data (FB Messenger, Skype, Chrome, WiFi passwords, etc), and her phone to function again. What do you think I should do?
I think I need an advice and suggestions from someone more experienced than me - I don't even know trusted sites where to download the firmware roms from.
The phone's details are (I'm afraid you'll have to walk me through to get more details to this list, as I'm new to the forum):
Phone: Samsung Grand Prime
Model name: SM-G530FZ
Firmware version: G530FZXXS1BQC2 (Android 5.0.2 with Baltic bloatware, I guess)
Now in detail:
My knowledge and experience regarding the smartphone software & restoration is very basic (I've only restored the firmware to a LG-L70 once some years ago, and that's it).
Before the problem I lost some over 600 media files from that phone by Cutting and Pasting a folder from phone's internal SD to PC's disc. Now I learned never to Cut-Paste important or irreplaceable files. The files ended up on the phone, because a folder with over 800 files couldn't be uploaded to the Google Drive (the camera's folder had over 1k files in it, so I moved some of them to another folder, which the phone created on the internal partition rather than the SD Card, where the original folder was from).
Instead of using a trusted software, I foolishly Googled a photo recovery program for phones, using my mom's PC. A list of bogus recovery program sites appeared (had to look them up on her PC, as I found only legit, widely trusted programs now, using my laptop. Those darn Google's personalized search result algorithms!).
Before using the dr.fone Recovery software I synced most of the data to her account.
Used the "free" dr.fone Recovery software as per its site's instructions, the phone did a restart and the touchscreen went unresponsive to touch. Later the software showed the lost files it found, and offered to restore them for a sum. Naturally I declined.
The software said that to return the phone to normal I need to disconnect the USB cable. I did so, but the phone's screen remained unresponsive to touch, even after restart (long-press [Pow] + [Vol-]).
I tried connecting an USB mouse via the dongle, but the mouse cursor didn't appear (maybe this phone doesn't have this functionality).
Now, after using that FAIL-covery program, I was overly cautious not to make things even worse.
I wanted to make a copy of the phone's internal SD state (or is it called a phone's hard drive?), to get the media files from the clone and to have a backup of mom's files.
But I failed: I downloaded APK, ncat, KingoRoot and BusyBox. Tried to follow the steps in this video: youtu[dot]be/KKkvkCgMeMA. Got stuck at "busybox not found" at about 10:27 mark in that video ("dd if=/dev/block/mmcblk0" "busybox nc -l -p 8888"). Turns out you need to run some of the apps from that phone prior to that step, and I don't know any workarounds.
Then I remembered that the files were on the external SD in the first place. Well duh! I then connected the Micro SD card to PC's reader via a Micro SD adapter. To make a copy of the SD card's 1s & 0s, and to restore the media files from said copy I used ZAR (Zero Assumption Recovery) z-a-recovery[dot]com/. The backup creation (an .ISO file or some such) and media recovery are free of charge.
Now I only need to remove duplicates and blurry pics (I think I had a Moleskinsoft's Clone Remover from an old PC magazine's CD lying around somewhere for the latter). Oh, and I better not forget to run a malware scanner on her PC and remove the mr.fone installed services and folders from it. Went a bit off-topic here, sorry!
Last I pulled a wifi passwords file with "adb pull /data/misc/wifi/wpa_supplicant.conf" command as per instructions on this page: mashtips[dot]com/see-wifi-password-android/. I don't know whether putting the file back on that phone will do the trick or not.
That's pretty much all.
I hope the situation can be resolved and I appreciate your input! :fingers-crossed: Maybe someone has come across a similar post, has constructive commentary or knows something obvious that I haven't come up with? Thank you in advance!
Edit 30 Jan '19: Got the phone working. Accessed the phone with a Chrome browser extension (name here). All accounts except some mail account were gone. WiFi didn't work.
Found a stock ROM here: (address here).
Found the Odin3 tool here: (address here). It came with a different locale ROM.
Flashed the 1st ROM with Odin. The screen started to work.
Flashed the 1st ROM with Odin again. The WiFi started working.
I'll update this with links soon.

I've got the exact same problem after using Dr Fone app!
Hi there.
I've got the same problem with my Samsung Galaxy Grand Prime after using Dr Fone, like you. I contacted Wondershare website from which I downloaded the app but they haven't bothered replying. Not happy at all!!
I contacted Samsung's support team and after trying different things (the usual stuff: reboot; remove the battery and SIM card; restart in Safe Mode; etc) which didn't solve the problem, they ended up telling me to reset the phone to the factory settings but that didn't work either.
Now my phone is stuck on the Samsung Galaxy Welcome screen which asks me to choose the language I want on my phone. The touchscreen is still unresponsive.
How did you manage to fix the problem if the touchscreen was unresponsive?
Thanks in advance for your help!

MTP Application Crashing

Where would I start to troubleshoot an issue with the MTP Application?
If I select the Media Player or Kies options, the MTP Application continually crashes and restarts every second.
I have connected the device in USB Debugging mode, then reconnected again and it still does it.
I've done the driver installation in the kies application and I've reset both the PC and the phone, behaviour is consistent. Kind of frustrating as I can't upload media (DRM....).
IF anyone has advice on where I could start troubleshooting this issue I would greatly appreciate it

Here is a fix my friend but say goodbye to your saved games and files..
[try transferring or backup your files using wifi or bluetooth in case you have important files on your phone]
[and also, try to backup your phone contacts to your sim because formatting will wipe your entire phone's data]
Once that is done, try to do the following.. go to Settings -> SD card and Phone Storage -> Unmount SD -> Format SD
Once you have formatted the SD card, go to Settings -> Privacy and then choose "Factory Data Reset".
Your phone should now be detected once you connect it to your computer this time around.
Hope this helps.
I've done this once before. I spent a significant amount of time getting the right data under my contacts and linking them properly, I need to know how to find out why kies is borked. Otherwise I'll wipe the phone and possibly be stuck in the same situation again.
Have you had this issue occur and this fixed it though?
I had similar problem. Tried everything you mentioned and nothing helped.
In the end I formated externas SD card. Flashed SG1 firmware and rooted the device (all done in a matter of 30 min).
It fixed the MTP aplication crashes (dont know what of three really did it).
I'd been having the same problem on my Galaxy S.
It had been working fine, and I've done nothing to the phone to change anything with it.
Just opened the MTP App on the phone, then just crash, restart, crash etc and kept looping like that.
(Mines the Optus AU version too - might be a problem with something on there?)
Anyways I used the WebSharing app to download all my files to a zip on my computer, then unmounted and formatted the internal SD card - and then rebooted the phone.
Once it rebooted, moved the zip files (unzipped) back onto the internal SD as they were originally and plugged into the USB and it all worked again.
Hello everyone, I'm new here and own a Galaxy S now for two weeks. Yesterday I to noticed/encountered the rebooting mtp application when plugging in the cable while the USB settings are set to 'connect to Kies'.
To be short I tried all offered solutions found on this topic on the web and in the end only the unmounting and formatting of the INTERNAL sd has helpt.
I made a backup via Websharing since selecting the 'mass storage' option didn't work for me yesterday. Obviously this is a slow way to make a backup. Try to only back-up what you deem to be imported files.
So the unmounting - formatting and rebooting (mounting) of the INTERNAL cards is the quickest solution and will safe you hours of work!
HOWEVER
Today I had the same rebooting MTP issue again. But since re-installing kies version 1.5.1.10083 I'm able to connect to the pc via 'Mass Storage'
You will see drive F: and drive G: if you at least succeed in connecting via the mass storage option.
I than did 2 things:
1.
I recently made some pictures and also copied some pictures from my pc to the G: drive ( INTERNAL SD) I renamed the pictures to short names so they didn't exceed 16 characters (one of the solutions I read online ).
2.
In the map data I found folders with the names of in my case Touiteur and Beautiful Widgets. Both folders contain a CACHE folder. I deleted the complete touiteur folder and thus also its CACHE folder.
Now I connected my Galaxy S to the usb cable again and behold, the rebooting of the MTP has stopped!
Now I'm not technical at all and have struggled with this issue the whole of yesterday ending up formatting my internal SD. And to be honest I don't know for sure what the working solution is in the end but can narrow it down to 2 things you may try if you can connect via the 'mass storage' option:
1. try giving pictures in G:\DCIM\folder name a short name if they are long or try to remove the pictures completely (make backup) just to see if either of this works.
2. Delete the CACHE folders in the APP folder under G:\data and see if this works
Again, I'm unsure what or why I solved it on my Galaxy S but give it a try if you have tried everthing else and do not want to format your INTERNAL SD
I've got a fix
Alright guys, I posted a video on how to repair the MTP application problem, especially for you spencee, check it out. Go to youtube and copy paste: MTP Application Crash Fix. And click the first one. It's by abrar447. Hope this helps!
Ok, I'm having this issue again! I watched the video by Abrar447 and deleted every single file in cash I could find ( actually did a search on the word 'cache' on the internal drive. Although I know this should now work my TMP application keeps rebooting. Am I missing something here ?

Thanks again for posting this video. It actually worked for me, been trying to find the solution to that MTP crashing problem when trying to connect in Kies mode.
narrowed it down
I have this problem too. I saw the youtube vid and decided i'd delete one cache folder a time to see what was causing the problem. Found out that is was 'Sound Hound'. So i deleted the cache folder, MTP worked, then i used the app so it would create another cache folder, MTP clashed. Did it many times.
Hope this helps.

Root + One Click Lag fix
Really weird problem , after clearing the cache it works again.
I reccomend using CacheMate for Root Users (free or pro) which you can find in the market , you dont need to delete all the cache manually then
Hi..
Anyone know the exact name for the MTP Application..is there a way to replace the problematic version with a working version..On my ship with ROM. i9000dxjf4..MTP application showed steadily without keep crashing..
MtpApplication.apk
MtpApplication.odex.
If anyone has the working version (no crashing on Kies connection). can post here..I would like to experiment to overwrite it with a working version..

Perfect solution. Did the clearing manually - no success. Only Cachemate did the trick Thanks!

Hello,
I also had a lot of issue's with Kies. I also tried a lot. But the one thing that helped was removing SOUND HOUND (application and directory)
Hope this helpes for some people!
Cheers
I emptied the cache under the Android folder and it started working again. The thing is, as soon as I open the gallery, the cache is written again. I'll try to see if the new update fixed the issue.
The problem is the not cache in itself. The bug is the '16 character extension' problem. Google it if you like. The solution is to delete all the files having its last extension greater then 16 char, in your internal or external SD card.
I asked about the fix on twitter, the reply was this.
I found a small program which tell you which files are the problem.

Hello everybody,
i'm a bit new to Galaxy I9000 but i had the same issue with Kies and MTP apps. Actually i found out that the issue seems to be linked to file extension longer than 16 chars. Usually those files are inside cache directories so, you should just cancel them to fix it. I've got kies running correctly since then (last update of Kies running n Windows 7 64 bit). I know there is also a little app to scan files to search the 16 digits extension called "FileSearcherforKiesFix.rar" you can find it and download just putting it in google.
Hope this can help!
Regards
Mic
APK version?

Is there an apk version of this? I'm unable to connect the phone to my x64 win7 at all right now...

Have tried everything and nothing seemed to work...
The "FileSearcherforKiesFix" finds some problematic files, but not all off them. Manually deleting long file names and cache folders seems to be insufficient either.. I think that there must be some cache files in other partitions that we cannot access via "Mass Storage" that are causing problems too. So we have to clear those files...
But thanks to a comment in this topic I have found a working solution:
1º Delete any problematic file with the "FileSearcherforKiesFix" method.
2º Use this app: http://www.appbrain.com/app/com.aac.cachemate.demo , with the option "PowerClear" turned on, and clear all cache from the phone.
After this the MTP thing installed instantly and now everything works.
NOTE: The "PowerClear" option may cause some undesired effects in some apps.. Backup first, or, use at your own risk.
For me the problem started when I copied lots of MP3 to my phone.
I solve this like this:
I connected my phone using the media mode.
Searched for all *.mp3 files
renamed them all to *.! (whatever extension)
(I use a program called FAR Manager, which is something similar to the old Norton commander, but for windows)
Connected with Kies and it got recognised
Hope it helps others

[Q] Boot Loop, help?

IN MY INFINITE WISDOM, I replaced my build.prop with the one from a Motorola Xoom in an attempt to get Sketchbook Pro to show up in the market. Now my tablet is boot looping.
I backed the original up in the same directory, as build.prop.OLD. If I could mount system and replace the file with a PC, I'd imagine that the tablet would work again. How could I do that?
However, THERE IS ANOTHER COMPLICATION! I used the 'Acer Phone Disabler' app to remove the telephony drivers, which means that I cannot flash a rom or the tablet will brick. I'm not sure what this means for Nandroid backups.
The tablet has the leaked stock 3.1 rom installed, it's rooted, and it has Clockworkmod recovery.
Thanks in advance for any help!
Oh god.
I used ADB to pull my build.prop.OLD, renamed it to build.prop, and pushed it back. Now... the tablet boots up, and it shows the Android "Welcome" screen. Clicking the only button available doesn't work. It just highlights as if it is selected, and doesn't do anything when I lift my finger up.
I DO have a Nandroid backup from several weeks ago of the same rom, but from BEFORE I removed the telephony drivers. I am only going to try restoring it as a last resort; does anyone have any ideas? Remember, flashing a rom would result in a brick because I used Acer Phone Disabler. Is a nandroid backup safe?
Thanks guys. I'm really hoping this tablet isn't too screwed.
I'm hoping someone else chimes in here but I am under the impressing that the nandroid backup would override any changes you could make as long as you don't break recovery. As far as my experience goes if you had a backup of your current configuration you could do an "advanced restore" and only restore your "system"

Restoring just system worked! My homescreen is back to stock but all my apps are still installed, so I don't really care. Thanks a bunch, I was so worried.
COOL!!!
Glad I could help.

Help needed for a boot loop
Well as said in the video, i reuse an existing thread about bootloop...
I'm stuck in a bootloop with an iconia A500... but let's look at the steps that got me there...
The First mistake was to answer yes to my friend who asked me to connect his Vodafone k3565 to his iconia A500, but as i read Android was linux based and i did use linux a lot as a student, i didn't even imagine it could go wrong...
Tablet was stating to run :
Android 3.1
Bernel 2.6.36.3-00009-9dddf6f2
Build 4.015.05-EMEA-CUS3
i did root with iconia root 1.3
then added Busybox and a terminal program.
reboot, try a SU and could access the devices
Here is the second mistake... i should have wondered how to restore to normal state before starting, because i don't have any SD card that suit the device ( mine are normal sized ones, you know.. Stamp sized :/ )
Then i got to the thread
http://forum.xda-developers.com/showthread.php?t=1058846&page=7
and i used an usb key to transfer it to the device, but before applying the files i took a look to them and found 3 of them would overwrite actual system files, so i did a backup of them :
/system/build.prop
/system/etc/apns-conf
/system/bin/rild
and looking at the build.prop i saw differences in the values of the one on the A500 and the one in the package so i decided to get only the missing lines from the new system.zip file and add them to the original file
And here is the 3rd mistake, and i guess the reason of the problem : i did that merge on a windows computer, and i fear it did add those pesky CRLF at the end of lines, turning my build.prop into a build.prob(lem).
I'm not sure, as i didn't check before it was too late.
rebooted and... boot loop, with 1 times out of 2, the little android with yellow triangle and exclamaition mark.
Cried, runned in circles, then looked on forums to find a solution.
Reboot with Power+Volume gives :
"Erasing cache before SD update...
SD update cmd:recovery
--update_package=sdcard:update.zip
Booting recovery kernel image"
Then i get the android with gears for a few seconds, then below him is a bar like the one in the android store when you download a file, then half a second later, again the exclaimation mark.
I also tried plugging a keyboard to hit the home key...
( in fact two : Logitech G110 and trust easy scroll silverline )
no difference, maybe because those are gaming keyboards and they arent loaded soon enough by the tab, or maybe it crashes before keyboard loading.
Tried then to install ADB using post
http://forum.xda-developers.com/showthread.php?t=1155664
hoping i could use the USB cable to put the backup files back in place but when i plug the device into the windows host, it recognises an unavailable USB MTP device, whose properties say "Acer iconia tab a500" in the "signaled bus description"(translated from french display, may be something else in english)
I manually force added the Acer ADB interface, but both the devices are unavailable to windows, with a warning sign, stating "this device cannot start (code 10)"
"Adb shell" answers "Error:device not found",which is expected, as windows can't see the devices properly
the strange thing is that, with USB plugged from A500 to PC, the Android with exclaimation stays forever, while without the cable, the system boot-loops
so i'm at this point :
i have a boot looping device, and the backup of the modified files on an USB key, and no way to put them back on device.
I found on the forums a lot of different .imgs that could be put on the /system to reload the device but none with EMEA-CUS3. So if i overwrite the files, i can't go back
I read you need a SD card to patch the device but not all of them work...
And my only computer with a SD slot uses a big one, not micro one, so i also need an adapter to write on the sd card.
Is someone near me (belgium/postcode 4000) having a SD ward working with the device who could lend it or help me doing the job ?
else
i saw in a nearby store ad "Sigma SDHC 4Go" or "Sigma SDHC 8Go", with apparently an adaptor for a normal sized SD slot, can anyone confirm it works or it don't work for sure ?
else
Can anyone tell me an SD card know to work, and being sold currently with an adapter so i have a chance to find one in a store near me ?
Is there a way to create an update.zip that will only update the files i did overwrite ?
if not, has someone an image for the same system i have ?
Well... lots of questions, but i'm very worried, especially as the device is not mine and not working anymore atm.
-> update
Looking closer at the modem (Vodafone k3565) it has a trap that says "SD card" so i guess i won't need an adapter... still need the reference of a SD card known to work for the restoring.
[bump] and more :
this thread http://forum.xda-developers.com/showthread.php?t=834144
lists working SD cards, but don't tell with which device. i'd take the guess it applies to the iconia A500 and take the list to the shop to see if anyone is available...
Did you install the Acer USB driver, found here? http://www.acer.co.uk/ac/en/GB/content/drivers
You might need to go into device manager after installing and right click/update drivers on the tablet, then manually direct it to the Acer driver folder. That's what I did, then ADB worked.

And here is the 3rd mistake, and i guess the reason of the problem : i did that merge on a windows computer, and i fear it did add those pesky CRLF at the end of lines, turning my build.prop into a build.prob(lem).
I'm not sure, as i didn't check before it was too late.
rebooted and... boot loop, with 1 times out of 2, the little android with yellow triangle and exclamaition mark.
Cried, runned in circles, then looked on forums to find a solution.
Reboot with Power+Volume gives :
"Erasing cache before SD update...
SD update cmd:recovery
--update_package=sdcard:update.zip
Booting recovery kernel image"
Then i get the android with gears for a few seconds, then below him is a bar like the one in the android store when you download a file, then half a second later, again the exclaimation mark.
I also tried plugging a keyboard to hit the home key...
( in fact two : Logitech G110 and trust easy scroll silverline )
no difference, maybe because those are gaming keyboards and they arent loaded soon enough by the tab, or maybe it crashes before keyboard loading.
Tried then to install ADB using post
http://forum.xda-developers.com/showthread.php?t=1155664
hoping i could use the USB cable to put the backup files back in place but when i plug the device into the windows host, it recognises an unavailable USB MTP device, whose properties say "Acer iconia tab a500" in the "signaled bus description"(translated from french display, may be something else in english)
I manually force added the Acer ADB interface, but both the devices are unavailable to windows, with a warning sign, stating "this device cannot start (code 10)"
"Adb shell" answers "Error:device not found",which is expected, as windows can't see the devices properly
the strange thing is that, with USB plugged from A500 to PC, the Android with exclaimation stays forever, while without the cable, the system boot-loops
so i'm at this point :
i have a boot looping device, and the backup of the modified files on an USB key, and no way to put them back on device.
I found on the forums a lot of different .imgs that could be put on the /system to reload the device but none with EMEA-CUS3. So if i overwrite the files, i can't go back
I read you need a SD card to patch the device but not all of them work...
And my only computer with a SD slot uses a big one, not micro one, so i also need an adapter to write on the sd card.
Is someone near me (belgium/postcode 4000) having a SD ward working with the device who could lend it or help me doing the job ?
else
i saw in a nearby store ad "Sigma SDHC 4Go" or "Sigma SDHC 8Go", with apparently an adaptor for a normal sized SD slot, can anyone confirm it works or it don't work for sure ?
else
Can anyone tell me an SD card know to work, and being sold currently with an adapter so i have a chance to find one in a store near me ?
Is there a way to create an update.zip that will only update the files i did overwrite ?
if not, has someone an image for the same system i have ?
Well... lots of questions, but i'm very worried, especially as the device is not mine and not working anymore atm.
-> update
Looking closer at the modem (Vodafone k3565) it has a trap that says "SD card" so i guess i won't need an adapter... still need the reference of a SD card known to work for the restoring.

The reason "some" SD cards don't work is down purely to formatting. Normally, reformatting them in an Android phone sorts it out. Not always, but normally. Don't worry about the GEN3 stuff too much, it's just regional variations anyway... More important to get the tab working again, no?
Yes i did ( on 2 different computers, just to be sure )...
and still the device is not recognised as "adb device".
Windows shows a "USB MTP Device"
Tried to manually add the "ACER Composite ADB Interface" and "ACER Fastboot Interface" to the installed peripherals, it shows with yellow exclaimation mark, never shows up running.
Without any useable answer about one week later, i did buy a Traxdata 2Gb SD card with adapter ( the cheapest i found with an adapter from micro SD to normal SD ) and flashed with the Emea_Gen3 ROM from http://forum.xda-developers.com/showthread.php?t=1113878.
Now the tablet works, but is telling me 4.010.42-COM-GEN1 instead of the previous 4.015.05-Emea-Cus3.
Seems to work correctly, so i go on with the modem connexion.

Help me please, how to restore original firmware?

Dear developers,
I have deleted (by mistake) program Launcer from my Smartphone and now it is not going to load. When I turn on it, there is only symbol of IDEOS. After a minute symbol starting to twinkle, but system not loading.
Could you please tell me how can I return to original firmware?
I hope someone will be able to support me.
If the launcher is the problem, you can just install another, or push again the original from a rom via adb. I assume that the device is rooted(I think you cannot delete a system app if isn´t). If you can connect to pc, then possibly you can install a launcher from huawei' s suite(I´m not sure because I don' t use windows and I haven't try this app) or from a android file manager like QtADB, Android commander or Droid Explorer. You can also install it only with adb via windows command prompt:
http://www.brighthub.com/mobile/google-android/articles/37151.aspx
And maybe, if wifi is enabled and connected, you can just install a launcher from market via pc' s web browser:
https://market.android.com/
The Modaco wiki has a list of original firmwares, but no link to Huawei works anymore. However, it is possible to download the latest China Unicom firmware - which does contain english language support. That should at least get you started.
As a new user I can't post links yet, but it is easy to find if you look for u8800 software, and then switch to Chinese.
Put the extracted directory (dload) on an sd card, in the top/root, put it in the phone and then hold volume down and power on.
Note, this will blow everything away to start from scratch so make sure it is what you want. In addition everything will be in Chinese so you need to be able to navigate to the settings to set it to English.
Better ideas? I am a noob myself so no guarantees...
I have unrooted it before to delete some trial games. And deleted Launcher by mistake.
I can't connect via usb now.
I'm afraid if I upgrade firmware, I have less memory because old one will not be deleted. Or maybe I'm wrong?
No, you're not gonna have less memory.
Did you tried to wipe to factory defaults from recovery mode(power button and vol+)?
You will not have less space because an original firware will format everything from boot partition, system and data... Basically , it will give you original software and status like it came from factory ... Like the other user said, jut find it, extract it , put the dload directory to the root of you sd card and hold volume down and start up the phone ... You will see a progress bar and when it is finished , the phone will restart itself, you will have to wait longer due to the creation of new files and there you go

Install recovery first, then you can connect your device to PC using recovery. If you have friend that have X5, copy the launcher. Else, just install Custom ROM.
The old one will be removed if you install custom ROM. If I'm not wrong.
Recovery.
Unplug USB, turn off your phone, press and hold vol + and -, then press power. Hold those three buttons until it turned on and the screen is purple-pink.
Backup all image data(copy). The rest is in the link.
Sorry for my English. Hope you understand what I write..

You are magician. it works now.
hmmm... but there is no launcher application - no workspace available. it doesn't want to load as before. strange.
upgrade don't work too. It is cycle repeating of step1/2.
I just tested and found that you can copy the missing apk from bootloader mode. In this mode(power + vol- + vol+ buttons), when connected to pc via usb cable all partitions of device mounted(at least this happens on linux). So, you can navigate to system partition on /system/app folder and copy there the missing launcher' s apk file. You can find this file on a custom' s rom(or on an official' s rooted rom like modaco's roms) update.zip file. It's on system/app folder. I tested this on linux and I could(not as normal but as root user though) copy or delete files from there.
dancer_69, thank you for your support. At my side when I connect via bootmode, there is only flashdrive is visible.
It's really strange that it is not going to upgrade.
I'm able to apply sdcard:update.zip. So maybe if to put this application inside of the card, it could install. but I don't know how to do it.
I finded apk file and tried to install it but it don't receive file because it hasn't some certificate. ???
I think you have 3 options here.
1. flash an official rom(you put the dload folder of rom's zip file on root of sdcard and boot to bootloader mode. The update starts automatic)
2. Use a linux system(maybe a livecd) to access the other partitions.
3. Try to reroot the device from pc, via superoneclick app(you can find it here), so to have access to system again.
but I haven't access to installation program area. nothing!
I have only ability by pressing (vol + and on) to choose install update.zip from flash card.
so.
1. when I runned new firmware from dload it didn't install. it was cycling at first level (1/2)
2. linux is good idea. but I'm not sure that it's will be profitable. maybe I have turned off access to partitions inside of phone
3. I can't install superoneclick as I'm not able to install any application.
I hope we are closer to some geniously idea. I have bought phone yesterday and we haven't service center in our city. So, I need to buy the other one.
This is not so serious problem, it' s not hardware, it´ software related. And I think you cannot turn off access so easy.
The superoneclick is a pc application. You don't need to install something on device(if I remember well, because I use it once before a long time). You can try it.
And you can try linux too.
I don't think that this is a problem that only service can solve it.
What firmware you tried? Try another one. And better try to find the one that you device has(if you know it)
Thank you for positive opinion.
1. Will try to change firmware as you said. Try 2 more firmware from Huawei.
2. Superoneclick needs approval from phone, today night I wasn't able to run it.
3. I'll try Linux too.

Thank you very much for your excellent support. It's work now after trying of other firmware. Everything is excellent now.
I only noticed that battery is no very capacitive.
Please, send me your paypal account, I want to donate you a little.

Can't write to the nexus 7 internal

For some reason I cannot move files via Windows 7 file explorer to the Nexus. I can and have done this on every other mobile device that I've had before. What's the difference? Why can't I place pics and videos on it?
A few more details would be super helpful to give you a good answer. Start with if you are running a custom ROM and what if anything you have tried to solve the problem.
When you plug in your usb look under settings - storage and see if there is the option to mount storage.
Note 2 - Nexus 7 - Charge - Player 5.0 - Fascinate

For some reason, now it's letting me even though I didn't change anything. Mods can delete this if they want. And thank you ezas for your reply.
Glad you got it sorted out.

In my limited experience using MTP (rooted stock N7 4.2.2 + Win 7 x64), what seems to work well is:
- copying files FROM the N7 which were already in the /sdcard mount point when the N7 last booted,
- copying files TO the N7 into a folder which already existed inside the /sdcard mount point when the N7 last booted.
(I should also point out that moving files this way seems to be 5-7 times faster than using "adb push" or "adb pull")
What seems to only work sporadically is trying to copy or write to things which were "recently created" in the /sdcard mount point. For instance, if you generate a large set of files using Android, you won't be able to find them from the PC until a seemingly random ? amount of time later. Similarly, if you create a folder on the N7 (let's say by using a file manager) with the intent of pushing some files there from the PC, you won't see that folder show up in a reasonable amount of time.
This behavior actually does make sense - in principle, it is impossible to allow instantaneous write access to a file system from two independent hosts without running risks of filesystem corruption. In previous versions of Android, external SD cards could be accessed using USB Mass Storage drivers, but only exclusively by either the Android device or the PC - never at the same time. The SD card had to be unmounted from Android in order to be seen by the PC.
But, what is curious is the delays involved. I wanted to do something similar to this the other day (copying a nandroid backup from the PC to a "new" folder on the N7), and thought that by correctly disconnecting from the PC followed by reconnecting to the PC would allow the newly-created folder to "show up" via MTP on the PC. No such luck however; I needed to reboot the N7 for that to happen.
Bottom line is that MTP will work (and quickly, too! - better than 10 MB/sec) - but only with the above limitations in mind. When in doubt, reboot the N7.

Unrestricted access to my memory card - is that possible?

Hi all,
First of all - forgive me if the subject has been up before - I did a bit of searching, but could't really find much about the subject.
I'm generally very pleased with the Mi A1 (my 4th "main" android phone after HTC Desire, SGS3 & OPO) but one thing that is giving me a bit of grief is this thing with access to my sd card, more precisely with copying content to the card by using different apps like root explorer, dropbox, dropsync pro etc.
Two very common actions in my usage are:
- Start an ftp-server on the phone and push new episodes of whatever tv-series I'm watching for the moment from computer to phone
- Open root explorer in my phone and copy stuff from my Dropbox folder to my phone (and back)
Neither of these actions can be done in my A1 (stock Oreo). The phone actually give the appearance of giving me the option to choose the sd-card but when trying to actually transfer something there it get's stuck before finishing or just return an error when trying.
So my question is - to get back to actually having rights to transfer stuff to my SD card without any problems, which of the below options would be the "easiest":
1. Does this work if I downgrade to Nougat?
2. Would rooting be enough if I stay on Oreo?
3. Can I transfer more freely with LOS 15.x?
4. Other options?
I actually found one thread mentioning this as a problem in stock Oreo so I know I'm not alone with the problem.
Thanks in advance,
/gosa
Hi,
Found this when searching Google for solutions this problem.
At the moment my only way of getting files onto the memory card is to download them to the internal storage and then using "Stock" file manager to copy them to the memory card... A bit to many steps if you ask me.
I was thinking that rooting might solve it but haven't gotten around to it yet.

Here one more with the same problem. I have the My A1 in ROM Stock Oreo 8 with root via magisk, and it is tedious and annoying not to be able to write to the external SD. I use ADM, apps for downloads Torrent, Solid Explorer.
Having Root I had the opportunity to try several possible solutions. Here some of them (note: none worked, nor resolved) I expose them in case someone else wants to try, possibly something will work for them.
Root ??????
SDFix: KitKat Writable MicroSD. (Developed by NextApp)
Magisk Modules??????
App Systemizer
ExSDCard Access Enabler
Xposed ??????
Marshmallow SD fix
KitKat SD Card Full Access (Caution: gives many errors in OS)
Handle External Storage
One way to take it with Solid Explore (it's more visual than the Stock Explorer):
* Solid Explorer, to paste or write to SD, always go to Root / mnt / media_RW / SD Card
As I mentioned. None of the above worked for me.
The only way to solve the problem momentarily is to download and use the apps all in the internal memory, with the stock file explorer moving the files to the external SD in a step later.
If someone can give light to this problem or a possible solution I will be very grateful.
*(sorry for my English)
Have you tried binding folder/creating softlink
Could you explain how it is done? Or inform about the subject.
Just got 8.1 and the problem is gone.
