Asus K00A (ME302C) - Android does not start. Bootloop? - Android Q&A, Help & Troubleshooting

Hello,
I have a tablet Asus K00A (ME302C) in front of me. Android can't boot. It looks like:
And so forever.
This happened supposedly after trying to restore the android to factory settings.
I've already tried:
- factory settings
- disconnecting the battery
- reinstall the system (cleans partitions and restart,
then again this loop).
Maybe you know how to solve this problem?

I came up with a problem and came up with a solution myself
1. Download the firmware in RAW format - from here: cloud. mail. ru / public / a10c34c64da1 / Original /
2. Format your MicroSD card to FAT and copy the downloaded RAW file to it
3. Proceed as for uploading an official ZIP file. Insert the card into the device, start the tablet with the VOLUP + POWER key combination. Use the volume keys to go to the SD DOWNLOAD position and confirm with the POWER button.
It took a while to check the checksums and install the software, but in my case it was worth the wait:

Deleted apps appear after reboot

Greetings.
Sorry for my grammar, I'm not a native english speaker, still learning.
I've got an unexplainable trouble, kind of frustraiting.
Phone: Galaxy Tab 10.1 P-5100 model.
Android: ver. 4.0.4
Stock ROM: official russian P5100XXLF2
The problem is, when I turn off and then turn on my device (or simply restart it) system is restored to some earlier state, this include:
1. Apps I've deleted are still installed.
2. Widgets or app shortcuts on 'home' pages are still on their old place though I've rearranged them.
3. Same with wallpapers.
4. Same with settings.
What I've tried:
1. Factory reset + cache clean. Even though it is supposed to be a full system wipe, it doesn't work.
2. Reinstalling Stock ROM via ODIN. Doesn't work either. Weird thing is, when I've done it before, it was done in about 5 minutes, but this time I've waited for about 1 hour.
Also there is a notice in android recovery, which states:
did not match sized '/system/csc/common/system/csc/feature.xml' (no data available)
Device wasn't rooted (whatever it is, at least I haven't done anything).
Yeah, I've used google search, It's a known issue but nothing useful was found.
Would appreciate any ideas how to fix it.
Added: also
1. I connect my device to pc via usb
2. I remove my music from device via PC OS
3. I disconnect the usb cord.
4. I reboot the device
5. Voila, music is still there.
did you fix this problem i have the same issue

[Q] internal storage : corrupted or writting problem ?

Hi,
I have a problem on my smartphone. (For info, it's a motorola atrix, running a Gingerbread stock version (no rooted, no operator specific version)
The problem is : all modifications done after a specific date (new photos, installed apps, send/received messages, preferences changes) disappear after a reboot. Same thing if I delete photos that were on the phone before that date, they seem to be deleted, but after a reboot they come back.
I tried to format, but nothing happened, the memory used stays the same, format is not done though no error message is thrown
The last test will be a factory reset ...
So I was wondering:
- is my memory storage corrupted ? is there any diagnostic app ?
- or is there any "read only" option in Gingerbread that I didn't notice ?
And jost for knowing, what is happening ? Do all the changes are saved in cache, so after reboot the cache is lost and I get back to the last "persisted" state ? Or is there a reset to the state at the specific date done at each reboot ?
Thanx for your help
Ok, I come back here because i need help with my problem, i don't have any idea ...
1) I have tried a factory reset (both mode, via menu, and external reset) : nothing happens, well it tells me it wipes data, reboot, and everything is like before
2) I tried to root the phone, with :
- Gingerbreak
- SuperOneClick
- Pete's Motorola Root Tools
- Unlock Root
Gingerbreak never ends, last time running but keep as it ... so failed
SuperOneClick and PMRT seem to do something, the phone reboot, but rootchecker tell me i'm not rooted
UnlockRoot i faild making it work
3) I check apps, installed avg (just to try, no more idea) but it saw nothing special ... I uninstalled some apps...
The result is same, after rebooting, all the modifications are lost (installed/removed apps, added/deleted files, system parameters, ...)
The only way I image now is flashing the bootloader & install a new rom ...
BUT it's a system, I should be able to see what is happening, which application is messing it up ? Is there an app that reset the phone state after reboot ? I don't understand ...
An help would be appreciated,
thanx a lot

[Q] Swapping internal with microsd bricked the phone

Hello,
So recently I got lack of internal memory(it is only 512MB though) and I tried to swap internal memory with microSD(marked as sdcard2). However, Im noob in this and after changing the lines I understood, that I changed sdcard with sdcard2(swapped sdcard and sdcard2), however, my android system seems to be not working now. I can boot and access settings, but thats all. No menu, no apps, no anything. Empty screen, only settings accessible. I cannot access any files or anything...
What I tried:
- Connecting phone to PC as I have Android Commander program which can browse system files from pc, unfortunately, failed to connect.
- Factory reset. Didnt help.
- Recovery mode - tried all options that are available, didnt work.
The phone is Prestigio Multiphone PAP4300 DUO. If there is any solution to that problem, please help. When I boot to the phone, I unlock it and I get many messages saying com.android.phone, system and such things stopped working. When pressing HOME button, it goes to home, but its empty(empty screen) and tells Launcher stopped working too. All I can do is access the settings. Cant call anyone though.
Please, give me a solution or tell me what to say to warranty service when I will bring the phone to them. Can they recognize that its rooted/that the vold.fstab file is modified?
Specs:

theunlockr.com/2013/07/29/prestigio-multiphone-pap4300-duo-specs/
That looks to be white, but mine is black.
I rooted it only. Havent done any changes to the phone until yesterday - swap the memories.
Thanks in advice,
Patrick

Hard way to learn the lesson that it's a bad idea to make changes to the system without having a custom recovery and a nandroid backup, hmm? Depending on how comfortable you are with using adb commands and if your tablet has r/w access, you could mount the system, pull the vold.fstab, undo the changes, push back, and set permissions. Can be a hassle though. Did you make a backup of the original file? But probably better served either reloading the stock OS with SP Flash Tools or see if there is a custom recovery / rom to flash for your device.

I can not factory reset my tablet

My current ROM does not allow me to Turn on the Debug Mode for some reason I don't know. The tablet is provided by our school so it has many restrictions like Facebook, Twitter and any other platforms that is not "trusted" by the goverment. The tablet is being updated like every day to patch the restrictions. I was be able to turn on the USB Debug mode but now they blocked it, too. So I decieded to get tablet back to factory settings so I will be able to Turn on Debug Mode and root the tablet and remove the restrictions. I do press Power Button & Volume Up button to open up Android System Recovery. The weird thing is I only have:
reboot system now
wipe data/factory reset
wipe cache partition
I don't have any other options like "Install from SD Cart" or whatever other tablets have. Anyway I do select 2nd option which is wipe/data factory reset option and Yes -- delete all user data option.
It says:
-- Wiping data...
Formatting /data...
.. and after a while it restart and opens up like nothing changed. Same tablet before I shut down. Neither 3nd option does work. Please help me about this tablet. What can I do to root it or make it to the factory reset?

Camera problem + Solution

Hi Folks,
Yesterday, out of the blue, when I tried to open the generic camera application to take a photo of my kids, the application never loaded. Instead, a black screen was presented for a brief 5 seconds, followed by a message "can not connect to the camera service".
I tried two different camera apps, same error message. Okay, the phone needs restart apparently, his uptime is over a month or so, so I did it - Same thing, the camera app won't load, and the flashlight is not functioning.
Okay, with the use of Google, I've tried several methods, incl. delete the cache partition, clear face recognition data etc. - none of them worked.
The last resort was to perfrom a full wipe/erase on the phone's internal memory and so I did - Didn't worked either. After a full reset/wipe and configurations (Google/Apps/Email/Whatever) Same thing happened again, like it was a hardware problem or something.
One last thing came to mind, as a programmer, I know that the wipe operation removes only the '/data' mount point, not the '/system' mount point and my guess was that something went corrupted with the camera service/binaries.
I went to the recovery menu (power off -> hold both power button & volume up for a 10 seconds) and I ended up downloading the latest firmware (.193) again from Huawei servers.
After that, everything is back to normal, and i've learned that the wipe stage was unneccessary. Hell, I could have saved all my data and configuration by doing the same without wipe my device.
So, for any of you that stumble on the same situation - Just go to recovery and d/l fresh copy of the latest firmware from Huawei, It will take ages (took me about 2hrs to download and i'm on a 500/100 broadband) but eventually it will solve your problem without loss of data.
Hope I helped someone.
