[Q] Will I be able to get my Bluetooth back ?

Hello there !
I can't toggle on Bluetooth in my GT-P3110 recently.. I'm not on airplane mode.. but WiFi works though...
I even flashed a CM ROM(10.1.3 right now) to see if it works.(may be an silly deed.. I'm just new to these android things)
I have uploaded two videos which shows what really happens when trying to turn on bluetooth...
When I was using the stock rom
After flashing CM
I think that I'm having some hardware failure (i.e. dropping the unit - I never dropped myself.. idk if it happened actually as I share this tablet with my family )
I want to know whether this can be repaired ?.
Is there a seperate accessory inside for Bluetooth which can be replaced ?
Thanks in advance !

Were you on stock firmware when you noticed your bluetooth is not turning on? Was it from the start of your new tablet? Take a look at this thread, someone has the same problem with you and solved it but his problem was caused of inproper flashing http://forum.xda-developers.com/showthread.php?t=2447156
You could also try to reinstall using wipe data/factory reset, wipe cache, wipe dalvik cache from clockwork mod and reinstalling cyanogen again to see if that fixes it.
As your last resort you could flash your tab back to stock recovery and fw (and use TriangleAway to reset your flash counter) and send it to Samsung for repair, especially if it still has warranty.

Thanks for the reply... I noticed the issue when I was on stock stock ROM. I may have to send it to Samsung.
Thanks for the support :highfive:

Is it possible you have another kernel other than stock?

[Q] LG G2X P999 screen not working once it goes to sleep

Hi my LG G2X p999's screen broke a while ago so I got the screen replaced and the screen didn't work so I brought it back to the store I got it fixed at and they installed a new screen and that one worked for a few months and is now not working, now the the screen will work only till the screen is locked and after that the screen will not respond to any touches, I am going to install a new firmware (I am right now running the stock firmware) but I am not sure if that will help, do you guys have any suggestions/help?
oh and I have been searching on XDA but have found nothing that relates very closely to my problem I did find one about the screen not working after 20 seconds but the situation was different.

I am not too knowledgeable when it comes to hardware issues. However, I would try to go ahead and flash a different ROM. CM7.2 is always a trusty flash. You can get the latest nightly from get.cm. Good luck.

Thank you very much, I will try that this weekend!:laugh:

Please, make sure to do a full wipe. Data reset, cache partition and dalvik cache, and finally format /system under mounts and storage.

Fixed it by flashing JB
Sorry for not updating this, I was able to fix the problem by flashing TWRP and a 4.1.2 ROM used the phone for a little while and didn't have any problems so this should be an appropriate solution to the problem.

[Q] after installing 4.4.1 - no cellular + data - SOLVED

SOLVED! see solution in the first comment.
I really need some help...
I installed manually 4.4.1 version using this guide: http://forum.xda-developers.com/showthread.php?t=2523217
(I am having a rooted device with TWRP without any modifications or deletions - used section B)
after the install successfully worked, i chosed to wipe. it was stuck and i used the powerbutton to reload device.
when the device turned on it used emulated storage which means no imei and no efs.
using the twrp (in recovery mode) i can see my full data and efs files.
when i am trying to rewipeqinstall update i get this error: "E:/Unable to mount /cache"
please help me.

Do not turn the device off while clearing the cache.
Reboot to recovery, go to TWRP settings and enable rm -rf option, go back and wipe the cache/dalvik. If THAT doesn't work, you will need to flash the cache.img from the factory image found here http://forum.xda-developers.com/showthread.php?t=2513701
After you do that, make sure you have the latest version of TWRP installed (2.6.3.4) If you don't you can also choose to install that via ADB before clearing the cache.

First of all - thanks for help.
already tried the rm -rf option unsuccessful.
2 question before I'm starting the flash process:
1. Is there a way dumping the efs folder to my computer before?
2. is this the command i should use: "fastboot flash cache C:/image-hammerhead-krt16m/cache.img"?
thanks a lot.

1. Use TWRP to back up your EFS data if you would like. You won't lose any data by just flashing the cache though. All your apps and everything should still be there.
2. If you installed the drivers correctly and that is the correct directory for the file on your computer, that is right! I put mine on the desktop for simplicity.

clearing cache/dalvik is very slow on N5, I found, and so is resetting the phone in recovery. though the progress bar may not move the process isn't stuck, it's still going on in background.

Flash the newest version of TWRP. The issue is fixed.

yeah i have a rma out for mine. Luckly i have a spare phone (its a damn $15 go phone) but mine is already shipped. biggest issue is the $440 is tied up in my account until they get the bad phone back. basically i would suggest to anyone that if they are going to flash a rom first thing they should do is back up their efs to their pc and also some sort of could (dropbox, drive, mega, box, etc).

Well in our case I have my efs on my PC from weeks ago restoring it doesn't fix whatever the ROM changed lol

[Q]Post-CM 12.1 Update Boot Issue

Hey all,
So ever since I updated my OPO to Cm12.1, I've been having boot issues. Essentially, what happens is when booting the phone, the phone is forever stuck on the OnePlus Logo without going ahead to the Cyanogen Logo and then the phone starting up. The way I deal with this is, I boot up into stock recovery and then "Clear Cache Partition" and then I reboot a couple of times, and this works and has worked for me over the last couple of weeks. However, I wanted to know how can I get rid of this issue once and for all, so I'm able to boot the phone normally without having to clear the cache partition all the time.
Thanks

Did you wipe properly when updating?

I think so,do you think that's the reason I'm having issues?
What would you recommend to sort it all out?

It's possible. I'd perform a full wipe (system, data, cache, dalvik cache) and flash again.

If you don't mind, could you share links that describe the easiest way to do all those things.
Thanks!

Samsung Tab 2 10.1 (CM11) unable to wipe/factory reset/install CM update

I have been routinely flashing CM 11 ROMs on nightly basis since the past year without any problems. However, the last Nightly I installed started giving me errors like xyz.process.com stopped etc etc. So, I decided to wipe everything through my TWRP recovery by wiping cache, data, internal storage (I have done this before for a clean install many times), but this time even when I wipe EVERYTHING and flash the latest nightly and the Gapps, the tablet boots into the same old version. I have done this repeatedly but with no success.
The strange thing was that when I even tried uninstalling individual apps, like I installed Whtsapp, Viber, Twitter, a few games, they did get uninstalled but on the next reboot, all the apps were back?! How is it even possible?!
Steps I have done to resolve this issue:
1-Flashed the newer ROM, nothing changed.
2-Tried wiping everything to no avail.
3-Tried flashing stock ROM like 20 times via Odin but it always fail midway.
4-Tried flashing Philz recovery via Odin, it succeeds but when I reboot in recovery, the same old TWRP recovery is there.
5-Tried flashing newer TWRP recovery via img file by booting into recovery,finding the img file and flashing it, it also succeeds but when I reboot into recovery, it still boots into the older TWRP recovery.
6-Tried flashing newer TWRP via Odin, it too succeeds but when I reboot into recovery, the old version is still there.
I mean, anything I do, the system wont change/wipe. Please help!

16gb Tab2?
Sounds like a emmc issue,maybe a emmc firmware update is needed to get back right access to your tab, in bad case the emmc needs a replacement. If you are from europe: i know someone from austria who can fix it for you. Added some notes about that issue on the faq on my github userpage.

Can you install https://play.google.com/store/apps/details?id=net.vinagre.android.emmc_check and post a screenshot of it?
~ All my work, news etc. on http://andi34.github.io ~

I tried install the app but was unable to as the gapp.google.com stop working thing wont let me. So I tried installing it through the web, it didnt install but the tab rebooted and is now stuck at boot. Wont shut down either

Update the emmc firmware (only via ISP possible) or replace the emmc. Maybe you can find someone who's able to do it...

Via ISP? Pleas explain. And are we sure that this is am emmc problem? Because I can boot and use the tab to some extent, it's not totally bricked I guess. What about the procedure here: http://forum.xda-developers.com/galaxy-tab-2/general/discussion-alternative-tab-2-emmc-bug-t3306862

I am not an expert on this, someone else would have to explain it if you have further questions about ISP etc.
I am quite sure it's the problem, if wipe / format does nothing and flash via odin also doesn't change anything... Your emmc is read only...
From the EMMC data sheet:
5.1.7 End of Life Management:
The end of device life time is defined when there is no more available reserved block for bad block management in the device. When the device reaches to end of its life time, device shall change its state to permanent write protection state. In this case, write operation is not allowed any more but read operation are still allowed.
But, reliability of the operation can not be guaranteed after end of life.

On a faulty EMMC firmware it happens a lot faster.
There's no way to boot from microSD, you would need to flash a modified boot.img at least which is imposible if the emmc is read only.
~ All my work, news etc. on http://andi34.github.io ~

Thanks for your input. Well, Odin is able to write the recoveries to the Tab, and shows that they are pass, doesnt that mean it is still writing? Also, Odin attempts to write the stock firmware but fails half way, I also also suspect a faulty cable. And should I try the procedure given in the link I quoted?
I am also downloading the Jtag suite like here: http://forum.gsmhosting.com/vbb/f672/p5100-how-repair-2118618/

Ok, I just saw your website https://andi34.github.io/faq_de.html I think I am screwed.
