General :: Android Device Cannot Write Anything Into Flash
Sep 9, 2013
I have a cell phone which name is Huawei Ascend P1. Now I have a problem, that is the devices can not bootup into Android's home and I can not write anything into flash, even using fastboot.
When booting, the screen stays on the welcome logo, and stay there forever, and adb could connect to linux shell on the phone. I can see all file on the phone, and I can save files after "mount -o remount / /", but after reboot, the file is gone.
If I use fastboot to flash a recovery into my phone, by follow command:
fastboot flash recovery recovery.img
The command line prompt says OK, but when it reboots, it still reboot into the previous recovery.

I have a standalone GPS enabled data recorder in my car that can function as either a USB host or device. (Its a class 0x00h USB device). I currently connect to it via a WM 6.5 app running on my Palm Treo 750. I would like to port my WM 6.5 app to an Android phone. (I don't have a specific Android phone in mind, I would like it to be as generic as possible).Replicating the GUI is not that difficult, but I am having trouble getting started on the USB communication. I'd appreciate it if someone could point me towards an example, or the appropriate tutorial.

Any app that allows you to download and convert flash video directly on your Android device? If I knew how to develop android apps I would attempt this myself. I use youtube downloader on firefox and was wondering if there was a similar app for that on Android.

I found out that you can use something like this to create a file:
CODE:............
When running the above code I get an IllegalArgumentException stating:
CODE:......
And Im guessing the "/" is not appreciated. I wanted the "/" since I need to write the file to the root directory of the device, as stated in the API in trying to follow:
CODE:.........
Question is: how do I place a file in the root-directory? I have been looking around for an answer, but havent found one yet.

I'm planning on getting my wife a tablet for christmas and the one I found is running Android 4.0, is it possible to copy my backup recovery from my N7 and root and flash the other device? If so, any other roms.

I need to write a fairly simple .csv file to the device's sdcard (so it can then be emailed via Intent). The below code does not write the file.
CODE:...........
More code here:
I flush and close out_stream. I can even seem to be able to read from the file on the device (printing above output, using fileinputstream, to an edittext.
How can I get to this file on the sdcard?

I have a completely broken screen/lcd/digitizer on my Samsung Galaxy S3, debug mode was not on. The phone works as it will still vibrate when turned on and the LED / Menu / Back buttons light up during a boot. USB connector works as well. The phone was not previously rooted.
I had most important data on the sd card and I've already wrote off any other data on the phone as I've since moved on to a GN2. I would like to make use of the S3 (not necessarily as a phone but a server, security camera, etc.). I've read several posts here about my options and looked at numerous google articles, all seem to require debug mode being on or assume/require the data/OS must remain as this is what the user is trying to recover. I do not care if all data is lost on the phone, I just want to make the device useful again.
Am I out of luck if debug mode was not enabled or can I flash through adb via some obscure mechanism? Also note that fastboot is not an option here as the S3 (samsung) does not have it enabled. I am unable to get into "Download Mode" as I cannot see info on the screen.

I deleted /system folder on my nexian cosmic journey. And now my nexian is stuck...
I try to using fastboot mode to flash recovery image, but my device seems not detected. I already installed the android composite driver, but when i use "fastboot devices" command, it shows (?) So how the heck to get my nexian back to normal?..
Or perhaps, if i just be able to put back the /system folder to its place again, it would be more easy to recover it... But how access the root when phone is like that?

I tried upgrading my Xperia x10 mini pro but my PC freezes at point where update tries to install SEMC drivers.
I have tried following things:
-Disabled the Anti virus.
-Inset USB cable to High power USB port.
-Reinstalled PC companion software.
I have seen one post where manually installing SEMC driver has helped. But I could not find the SEMC drivers at Sony Ericsson web site. I am using Windows XP SP3 32-bit.

So since the day I got my Eve (GW620) it's had a tendency to drop 90% of the calls I'm on, usually within the first 2 minutes. I've had all intentions of sending the device back for a replacement, which is why I paid the extra $50 for the warranty, however I've been lazy and it never went back. The device hasn't been used since July, until today. I found out that OpenEtna had got a working 2.2 Froyo ROM for the EVE, so I figured what the hell, let's play with this thing. So anyways I took it out of its box, rooted it, flashed it with the custom 2.2 ROM and was loving it, until I made a phone call and it dropped (after about 10 minutes).
Now for the last 4 hours I've been trying to find an original Rogers ROM to flash back to the device so I can ship it back and get a new one but this seems to be impossible - so to my fellow Eve owners, does anyone have the original Rogers boot.img and system.img for the Eve, or know where I can find it? Or anyone who has not installed a custom ROM, would you be willing to make a backup, factory restore, make another backup (with Original ROM), send me the boot.img and system.img, then reinstall their first back up?I did try tolemac's toleROM which is a 1.5 ROM, but it's custom too, already rooted with none of the Rogers apps.

Been an increasing amount of talk lately about Froyo (2.2) and how it will have flash and all that jazz. I use a non-rooted, standard ROM Droid, and I'm wondering how well it will handle all of these improvements. I assume the newer android devices with their gHz processors will do fine, but how do you think us Droid users will fair? And don't just say it can handle it. I know it will work, but how well is my question?

Basically I have an old iPod touch 2g on iOS 4.x and a Nexus 5.
I want to use my iPod as my media player but I'd like to be able to control music from my Nexus (only basic controls).
Is there an app on either device that allows this? I know tsk skipping can be done by some Bluetooth headphones so I'm hoping there's a way to make iOS accept command from my Nexus

My S4 died from a smaller than hairline crack in the display - Cha-ching! $175The cat knocked my laptop-the same one on which I had just successfully re-flowed the video chip-off on the floor, breaking, of course!, the screen - ~$50 (when I get around to it)
Now, the first time I try to add some new tunes to my "new" phone, I can't manipulate any data on its SD card via WiFi. I can write, delete, move, rename, anything I want to/from the card from within the phone itself. Just not over WiFi.
I thought it was perhaps the app I was using so I tried another but same thing. The best error code I get is the highly informative "Operation Failed"-Period.
Is there some setting somewhere that holds sway over the ability to write to the SD card?

I have a tablet with internal SD (nand one) and an external SD.
Now I can read contents in internal SD but can't write it. I checked up with root explorer, finding the file sysytem is "read only". After toggling it to R/W, the storage can be written by root explorer but still can't by other apps.
================ EDIT ================
p.s. When connected to PC as massive storage device, it can be read and written.

I am trying to port cwm 6.0.1.4 for my HTC Desire S via the cwm builder. Its running so far, but not exactly working, because it doesnt mount all partitions correctly. So i assume, there must be something wrong with my recovery.fstab. I used an older recovery.fstab i found on the internet, but maybe it hasnt got the right "options" to mount all partitions correctly.
So, how to make a working one? Which partitions are needed and how they have to be mounted?

I did a backup using Titanium Backup and Go Backup and after wiping my Motorola Defy, tried to restore apps, contacts etc. The problems I encountered were:
1) Go Backup can't recognize backup directory on SD card for some reason.
2) Can't move apps to SD. An error occurs: "Move Application: Failed to move application. There is not enough storage left." Needless to say, I have more than enough storage.
This is was I encountered by far, although I believe these are just a small part of the symptoms for a single problem.
Maybe its because there are no permissions, or moving apps is impossible because of an existing app files on the SD card.
What is the actual cause for this? Or is there a tool to fix the permissions on the Defy?

I'd like to know if there's a way to write files into the main directory just before the system shutdown, something like this:
End all processes (-> unmount disks?) -> mount /sdcard rw and / rw -> copy files from /sdcard to / -> unmount disks -> shutdown/reboot
Same with boot image (flash, in this case, and not copy / mod files)... is it possible? Or do I require to boot into recovery for these operations? I know I can remount as rw my system directory via ADB
Also, is it possible to do the same thing with the build.prop file? This, or during startup (before mounting partitions with standard permissions).
Of course, this having root (but not a special kernel to enable this kind of "before mounting" thing).

Few months ago i installed CM9 on my Galaxy Tab 7+. Everything worked fine to begin with, but after a while i was unable to delete stuff off my microsd card. I wound up buying a new card, copied the music and tv off the old card and installed it. Same problem. Now i have 2 microsd cards that I'm unable to write to at all. I can't write anything to them, can't delete anything off them and can't format them. I've tried using them both in my phone and on 3different Windows PCs with the same results. I have tried the SD card write fix referenced in the Galaxy Tab Plus development section and that didn't fix anything. The problem seems to be with the cards themselves, not the tablet (and phone and multiple pcs).
