Hi,
I have a Pioneer XDP-100R (hi-res music player) running android 5.1. I tried to root with SuperSU. At the end it asked to reboot my device. Now it's stuck on the android boot logo.
I can access the recovery menu (next track + power). A message is displayed: "E:Can't open /dev/block/platform/msm_sdcc.1/by_name/misc (permission denied)".
If I choose Wipe Data/factory reset, I get:
-- Wiping data...
Formatting /data...
Formatting /cache...
Data wipe complete.
"E:Can't open /dev/block/platform/msm_sdcc.1/by_name/misc (permission denied)".
I get pretty much the same when I try to "wipe cache partition".
None of the two actually make a difference.
Previous track + power is supposed to get me to the fastboot menu but it's stuck on the linux logo.
I had made a backup with adb beforehands but I can't restore it. adb won't see my device unless I select the option "apply updates from adb", but in that case, the only command it accepts is adb sideload.
I have not installed a custom recovery as my device is too rare. I never managed to find a stock rom or custom rom for my device so I can't even flash another one.
Has anyone any clue?
-- edit
I couldn't find any solution anywhere. I had to return it...
Thanks heaps
You could have some useful informations on forums or the page http :// xdp-100r.tk
I still have the device running if anybody needs files or tips.

Hello,
I have a Allview Speed City tablet, and after i installed root on it, i changed the dpi using an app..
(root thanks to mad_ady, root availible at http://forum.xda-developers.com/showthread.php?p=40740061#post40740061 )
After this, the tablet is stuck in a boot loop.
I tried to do a factory reset from recovery mode, but this didn't solved the problem.
(the tablet has only 2 buttons, power and home. The recovery can be accessed pressing and holding both buttons until the recovery boot).
I located the file where the dpi is changing, /system/build.prop , and tried to flash another file from Onda 701 ROM (a very similar tablet). I didn't managed to find the original file. Anyway, the flashing didn't succeeded, "instalation aborted" appeared on the screen.
I found on some forum a flashable zip with build.prop from another device, and i replaced the build.prop file with the one from Onda ROM, signed it with a tiny program and still fails.
What options do i have to replace/edit the build.prop file? Before bricking, the ADB was not turned on on the tablet, and i read that i cannot use the SDK (anyway don't know how to use it). I contacted Allview and they don't want to give me the ROM from the tablet. And so, i call anybody that can give me a backed up rom from the tablet, anyone who have the knowledge about AD ROMS and are willing to help me..
Thanks folks!
I installed ADB on my pc and tried to pull the build.system file from /system on tablet, but i get error:closed.. I tried to run this command with tablet in recovery/ apply update from ADB.. Why do i get this error? the device cannot recieve other commands than adb sideload?
Thanks..
this worked for me for full reset

this has been done with the allview speed city
I had a simular problem...
here my solution, hold on and home button at the same time until the screen gets back
wait until you get the boot screen...
use both, 1. erase card and 2. media options...
then to be save I choosed the other option say something like for factory reset.
the I used the apply update from ADB...
the tablet shows the same screen for 5 or 6 minutes
after it booted normaly, but I still had some problems
and I used a needle for a reset...
after that the tablet worked fine
the only thing what I dont understand is why its still root
Thank you for this tutorial, but i solved my problem with warranty. Even so, i erased all cache, factory reset from recovery but still i had no access to system files, and factory reset didn't changed the build.prop (system settings) to defaults.
It's normal. build.prop is part of /system (and the su binary is installed under /system as well), and any changes you make to /system files are permanent until you flash a different firmware.
Hello, I'm a little bit new to all this, so any help and detailed instructions are very very helpfull.
So I have Gigabyte GSmart Aku A1 device (MediaTek 6589), I don't know if it's bricked or what but apparently is not working quite well.
When I turn on my phone, it just loads and loads and loads and nothing happens (waited for about 4-5 hours), that was starting to happen after I somehow installed CWM on my device with some tutorial, CWM worked for the first time and after next reboot, it disappeared and stock recovery came back (and the problem with infinite loading screen - only showing logo).
I have ADB drivers installed, SDK aswell, tried to put stock firmware (got it from official site) and in like 1/4 of installation it says:
Code:
symlink: some symlinks failed
After that, I tried to install few versions that I downloaded from that official site, but same error again and again. (I tried to install with SD card and with ADB too. ADB is only working when I go to "apply update from ADB" in recovery. I have also used 2 different types of SD cards.)
That didn't worked either, so I got to some russian forum, and using google translator I downloaded 5-6 types of custom ROM's / Firmwares. That didn't worked either, one time when installing one of those ROM's - it said something about signature..
After that I was trying to install those ROM's with ADB and with SD Cards aswell, but turns out that every single time I get error saying: "Installation aborted.".
I have ofcourse tried to wipe data/factory and to wipe cache too, but nothing helps..
Also, when I'm in ADB console, when I type any command besides adb sideload or adb devices, I get error saying: "error: closed". I cant get into fastboot with adb console.
I really don't know what to do anymore, so any help would be very very appreciated. Thank you for your help in advance, if you need any videos, pictures or something, just tell me.
Edit: When I go to "wipe data/factory reset" in recovery, it says: "Mount /data error.".
BUMP!
BUMP^2!

i would look for stock rom in form of full mtkdroidtools backup and preloader drivers for your mtk chipset
and flash it using flashtool (it uses preloader[you can determine if it's available/undamaged by turning phone off and opening device manager on pc and plugging phone to pc if there will be a flash in device manager before the charging starts it will flash ])
Hello there,my Wave 8 HD+ stuck in android boot logo. I downloaded the wave8hd_20151105_v1.8 update thru wireless update and install, it says error in installing:
E:error in /mnt/internal_sd/adupsfota/update.zip
(Status 7)
Installation aborted.
My tablet is now in recovery mode and cant move highlight due to no volume buttons available,i can only select the "reboot system now" option.
Any other alternative for volume button so that i could just do the factory reset??
I also followed the detailed instruction on bluewave website on how to update the said Tablet thru PC but to no avail.
i emailed both the Telecom Company from where i get my Bluewave Tablet and the Bluewave Customer support but until now they stiil haven't replied yet.
thank you very much for your immediate reply.

hello, jho_zep, thank you so much for your reply, i am now able to move the highlight to select using my mouse, but still when i try to update from ADB, it tells me to send package to the device etc.. and i also tried to press the power button, it wont reboot the system, it would only shutdown the system.. another thing, i still cant get rid of the system update. " installing system update" then error comes in, my android is down.. i tried wipe date/ factory reset, still nothing.
Thanks in advance
Do you already solve your problem? because I have now the same problem as this.
I have pressed the wireless update then it restarted and it says an Error status 7.
I don't know what to do and how to deal with this problem.
can you help me?
My nextbook tablet rk3026 has a partition named metadata that holds the recovery boot commands. You could possibly try to wipe it and do a factory reset. I don't think it actually gets mounted so you would need to find a file the same size as the partition and dd to it. Or back up your system with rockchip flash tool then using a hex editor replace all data in metadata image with zeros. Obviously be careful. Here is a tool download with included guide credits to finless at freaktab(not sure if he is here at xda) for posting it.
http://freaktab.com/forum/developme...p-your-rk-device-rom-with-the-new-rk-2-1-tool
as always BACKUP and know if you don't do it correctly you may get a brick.
thank you for the response Destructos. but that solution won't help for my freakin weird tab 33gt HD+.
I get frustrated now
Problem solved
first thing to do is make sure that you have already installed the rkchip_usb driver in your computer.
What are the requirements?
1st of course your Tablet and Cable Connector
2nd Finless ROM Flash Tool v1.37
3rd Rokchip BatchTool v1.7
4th the update image/firmware for your Bluewave 8 HD+ that is downloadable from their official website
Steps:
1. off your tablet and connect it to the computer
2. open the Finless Rom Flash, uncheck all the boxes
3. turn ON your Tablet (be attentive) and while the blue screen is starting you may NOTICE that the ROM FLASH TOOL detected your device, it says "RKAndroid Mass Storage USB". when you have read that, press immediately the "Reboot Flash mode" and your device will in black screen. but ROM Flash tool still detected your device as "RKAndroid Mass Storage USB "
4. Open the Batch Tool, (you must know how to use it) find your image, then you will notice that the CONNECTED DEVICES below have color green, in that case you may now Click UPGRADE. wait for a minute and booooom, you device is functionable again.
have a feedback if it is helpful.
P.S.
before I go to that steps, when I am stuck in RECOVERY MODE of my device, I Click the Recover from BACKUP then my tablet restarts and it turns to BOOTLOOP and repeatedly saying NO COMMAND.

Why is it, when I do this, my tablet can't be detected by the software? I'm stuck on recovery mode. When it's on the blue logo, still does nothing.
I can only see my device when I look for it on Device Manager under Android Phone. Why is that? It doesn't show the "Other Devices". I've installed the driver but to no avail, still fails me. Please help. Thanks!
heyo, i'm new here, i don't even know if i'm in the right place but welp..
the thing is that i need help
i have a huawei p6 ascend, the screen was failing and one day it just died and revived few days ago
but it's a bootloop, so i was going to factory reset and then boom, failed to mount /cache /data (invalid argument), so wipe data and cache show a big FAIL, and can't install a rom, still fails
i know this problem is common and probably here in the forum but i really need help, things that i tried didn't work
i tried some things, like adb to try to install TWRP (it seems that it could help) but usb debugging is disabled so adb won't detect my device, tried to install rom through "dload" pressing volume + and volume - but nothing, it takes me to the recovery menu soo... :/ and then i tried the huawei miracle box, but ehm, my main pc detected virus and then i used a "disposable" pc but it didn't open
any suggestions? thanks
Hello
While using the tablet, several errors were displayed continuously on the screen. I do not remember exactly what the text of the errors was.
The error was almost identical to the name of the system files that had a problem with them.
Clicking on each error quickly displayed the next error. As long as the system hangs up, I have to reset the tablet.
When the tablet was reset, the system did not go up and it was constantly reset. After 3 or 4 times the reset enters the Recovery Mode.
The following errors are displayed in the Recovery Mode:
Mount Cache (Invalid Argument)
I run the Wipe Cache Partition and the problem did not fix.
I did Factory Reset, but it was not successful.
I installed the Phone Flash Tool and used the following rom:
http://gsm-firmware.com/index.php?a=downloads&b=file&id=20427
But when it comes to executing the "oem start_partitioning" command, it timeout. The device will reset and the error will be displayed below:
EFILINUX ERROR [start_boot_logic: 431] No valid target found. Fallbacking to MDS.
So i tried to follow the strategy written here:
https://forums.lenovo.com/t5/Lenovo...ollipop-5-0/m-p/2204562/highlight/true#M27284
I downloaded the IntelAndroid-FBRL-07-24-2015 program and I run Part 2 / T4.
I have downloaded the TWRP backup file but I do not know what should I install.
So if the solution outlined above is correct, help me do the rest. If I have to do something else, I'd be happy to guide me.
No one can help me?
