Hi, my phone is currently running on ICS stock, the sweden version (Q9). Some time back, just to see what it was, I had encrypted my device. I faced some problems regarding touch and USB port, so without decrypting it, I flashed a GB ZSKK5 ROM. It showed some error while flashing that ROM, so I flashed it again and this time it got flashed successfully.
Then when all was good and nice, I flashed the ICS sweden version again. This time I faced problems like 'closing of android.phone process' etc. Also when I go to recovery mode, I see th android logo with a orange exclamation!! Also none of the options work in the recovery mode.
Has anyone faced something like thiS? Any help will be appreciated. Thank you.

Ok thanks guys
Also, none of the options in the stock ICS recovery mode are working. Is this normal too? A bug in the ROM etc?

no success (multiple attempts)
PLEASE help me !!!

Hi man, if you can't get to recovery on your phone, the only way to fix it that I know is to flash stock .ftf firmware via Flashtool using your PC (you can try to disable data and cache wiping if you didn't make backup) - both you can find and download here on XDA

can you tell me more what apps you've installed instead of stock..
did you flash any package that includes init.d files
the upgrading message is a normal thing for rooted phone as it write/check the cache file back

Maybe you can test by uninstalling greenify/fullscreen...enter cwm than wipe cache and dalvik..but before that please make nandroid backup....then see it for 1 day ..if the problem still occurred than you have to try flashing method

the wiping is correct then you have to try another method..
before flashing enter cwm, format system/cache/data then turn off the phone to make sure everything is cleaned..
i think your phone will stick with unlock bootloader..
for rooting just flash extended kernel...
for app and extra backup i suggest this app
normal
pro

Hi,
I've checked the forum, found something relative but didn't help.
I have my Nexus S rooted for about 2years. I have changed a lot of ROMS with no problem ever.
About some months ago I flashed a new kernel so I can read usb flash drives. That didn't work.
But my phone was working right.
Then I realized that I don't have root permissions.
I don't know if that is the problem and if that is indeed the problem I can't find the original kernel so I can make it rooted again.
I have tried flash cwm6.0 and then new superuser.zip all installed fine but no change to my root permissions.
thanks in advance for any help.
Flash your ROM again. No need to wipe data or anything again.

Hello everyone,
I just joined this forum and i need some help.
I've got a very wierd problem with my samsung galaxy tab 2 7.0
Tablet: Samsung Galaxy Tab 7.0 GT-P3110 model.
Android: ver. 4.1.2
So the story behind my tablet is that my dad bought it when he working in another country,when he came back he told me that he had a broken galaxy tab 2 and he asked me to try to fix it,the problem he reported was that the tablet sometimes restarts,alot of programs have crashes and the wierdest thing is that,when I turn it off and then turn on the device (or simply restart it) the system is restored to some earlier state, this includes:
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.
So i tried the following:
1. Factory reset + cache clean. Even though it is supposed to be a full system wipe, it doesn't work.
2. Reinstalling a Stock ROM via ODIN. Doesn't work either and it takes about an hour to do...it says it was successful but it doesn't change anything in the tablet.
Also there is a notice in android recovery, which states:
did not match sized '/system/csc/common/system/csc/feature.xml' (no data available)
This device wasn't rooted.
So i you would ask you guys for some help,thanks.

My line of thought is that if you do root it, you can format the system partition which would more than likely fix this issue. But like I said, more than likely, there's no guarantee because it might be a hardware issue. Have you considered sending it in for repair? Since it's not rooted they would do it. If you don't care to send it in and are just trying stuff to see if you can get it working again, then rooting it wouldn't hurt anything. But that's your choice.

OK, so here's where just rooting won't help. You have two options: 1) Find the stock ROM at Samsung and have it on your SD card. Or 2) choose another ROM. Whichever you choose is up to you. You're going to have to format your system in the custom recovery, by doing this your tab is wiped of all info including the stock ROM. If you format system you won't be able to boot into your tab without flashing another ROM after. If I'm repeating stuff you know, I apologize. You'll need the ROM you choose on your external sd card, because you'll want to completely format everything (except your ext sd). If you know all this, try it out and see if it helps. If you want to learn more and the steps, PM me, I'll help as much as I can!

Hi, i'm facing the same issue here. Then I've try to root the phone but failed. Can help me too Sir?
For now it can't repaired, It,s known as emmc brickbug, find the xda forum thru Playstore emmc brickbug check. In Indonesia there is website that claim can repair it by replacing the emmc chip/internal memory, but it's not proven yet, since no body in our Galaxy Tab 2 facebook group has confirmed it. More than 15 people in the group has reported this bug, and the only way to fix it is by replacing the mainboard in Samsung Service Center. I also have replaced my wife Galaxy Tab 2 10.1 mainboard with the same case. In Indonesia the cost is about US$100

Wifi is working again.
I installed certificate from adclear app and rebooted. The reboot was stucked at google logo for around 60-90 seconds and then boot animation started.
i started cleaning my interner storage as i was preparing to backup on pc and flash mra58k image. And uninstalled android authority app. And deleting all the folders that were just eating space.
Any ways thanks for your replies.
My mac address also is reverted back to original one.
The wpa supplicant is also now having around 10-12 lines then my wifi details.

It's not software. It's failing hardware. Your Bluetooth will also stop working, as it's the same chip. Mine does the same thing. I've flashed multiple ROMs and tried changing wifi system files. Nothing has helped...
Sent from my TARDIS
I bought my Nexus 5 the first month it came out. Since then I have never touched the original system or even root it. About a month ago my wifi suddenly stopped working. I have decided to root and flash roms, after factory reset and basic solutions on google didn't work. I have tried a couple of different roms all on android 6 and 7. Wifi still not working. I havent tried flashing kernel and I don't have a file called /persist in the main directory...
EDIT: Cellular data & Bluetooth working.
If changing software and resetting doesn't fix the wifi problem, it's probably a defective wifi chip. I have two nexus 5 motherboards in my desk drawer with no wifi (tries turn on but never does or turns on then off by itself) but cell and Bluetooth work.
