I did flash the stock rom: N7000XXLT9_N7000ITVLT3_ITV

Now i have to redo the root, but i do not remember which one Philz i used last year to unlock my n7000, i looked here: http://xdaforums.com/showthread.php?t=1901191 but not i find the version LT9 Philz ... what should I use?

If possible I would like to use Philz because it solves everything with a simple flash from recovery (stock kernel + root + safe recovery)

I want to root my samsung captivate and install CM on it but i do now own a computer, and i do not want to "BRICK" or damage my phone. is there a way to manually Flash cm to install the recovery. Also could someone give me the "update.zip" that i have to flash to my phone to install CM.

I am a seriouse Noob at this.

Help.

thx,

In my experience the 3e recovery that prevents the flashing of unsigned zips has to be replaced by the previous version. If you can get access to a computer with admin rights, it takes no more than 20 mins.

Hi guys i'm using OmniRom with franco.Kernel

But something is killing my battery.

After restarting my N5 everything is working properly again.

After a few hours my battery is dying again

How do i find out whats causing my issue?

I guess it's an app

Android os is built up from services, like sync and location, from all apps.

So yes....things like Facebook especially, will make android os rise.

Go a day with location and sync off....and disable Facebook and similar social apps syncs....just to test. You'll see.

The more you run...the higher android os will be. Its just life. Have to decide what's most important. Those apps and services, or battery life.

[Nexus 5 Q&A, Help & Troubleshooting] leAndroid91:
Maybe you're right, i don't know.

But there is one thing i don't understand:

My CPU freq was still on max this morning (Nexus has been on charger overnight of course).

After rebooting it everything was normal again.

Then i manually startet facebook and the facebook calendar sync.

After it has finished the cpu freq was at 300Mhz again.

So i don't get why those app should force the CPU to stay at that high freq.

Ever after closing G+, FB etc. after using it the CPU freq stays low.

Every few days i have this strange behaviour and i don't have a clue why.

I'll give the disable service app a try but i'm not optimistic.

Isn't there an app which shows me which app, service, etc is currently using my cpu?

quick system info shows 0-1% to every app :confused:

[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] nikhilnagaraj24:
Hello,

I am in a bit of a pickle now. I followed the following thread

http://xdaforums.com/showthread.php?t=2469075

to flash the build.prop to transform my Tmobile Note 3 to ATT boot logos, animations, Google Play store and so on. My Tmob Note 3 is unlocked using Chainfire RegionAway app, but I also have a legit unlock code from t-mobile too. I have tested an ATT sim card and it works with full LTE (manually updated the ATT LTE APN)

I flashed the 3rd file from the thread through Phils recovery(full transformation), but the phone is getting stuck on the ATT boot logo. I then rebooted back to recovery flashed the file from link 2(higher data speeds). Still nogo. I then removed the battery, wiped all data/factory reset through recovery and still stuck on the ATT boot logo. I finally ended up flashing stock touchwiz (Kitkat 4.4.2) through Odin.

Did I flash them correctly or is there a different/more correct way to flash? I need the full transformation with better data speeds, so which one should I flash ( 2 or 3 or both?). Whats the procedure to flash these files and in what order and what files to avoid being stuck on the boot logo. Is a ATT sim card a must while flashing these (I dont have an ATT sim at the moment).

Any help is appreciated.

I also posted the same question in the respective thread too, but I have been wrong and been asked to post such question in the Q7A section

I can not get into the room and I can get into CWM. I've done factory reset and wipecache, I returned instal to the room, and nothing, enters the boot but does not start with the room.

[LG Optimus 4X HD] SimonTS:
As you stated in your first post...

It has been stated time and time again that your must NEVER carry out a vendor OTA on a rooted or modified device. It causes a problem 90% of the time as the OTA has no flexibility to deal with something it isn't expecting to find - so you get exactly what you have.

Just be thankful that it is almost impossible to hard-brick our device or you really would have a paperweight. Instead you just need to search and read a little to get it back up and running.

You need to get your PC to recognise the phone, thats the first step in this repair (unless the usb port is broken, there's no reason why it wont recognise, whats your OS and version, usb 2 or 3?)

why not put cm10.1 on a microsd and flash it from there?
[LG Optimus 4X HD] Flying_Bear:
it still won't work, after upgrading it ota while having custom recovery installed, a person will be locked to recovery for some reason (atleast other people were). the only way to fix it that i know of is to reflash a kdz

cmon, pay some attention :p you don't need to turn on the phone, or boot into the system itself to boot into s/w mode. now, there are tons (like 3 or 4 guides, plus many other topics opened by people with exact same problem like you) threads that tell you what to do (hint: figure out how to boot into s/w mode), so i'll let you search around for the guide.
[LG Optimus 4X HD] balloon27:
I suggest using this method: http://xdaforums.com/showthread.php?t=2682146

It's easier, faster and safer than flashing a .kdz file. (Plus, it tells you how to get into the s/w upgrade mode!)

Greetings from my Nexus 7 FHD!
[LG Optimus 4X HD] Flying_Bear:
I think this method also flashes a kdz, but does it automatically for you. But yeah, this one is easier than manually flashing. Thanks for posting it ;)

Also, thiy method will format internal sd card. My suggestion is to do a data/system format from cwm before you go in to flashing a kdz, either manually or automatically, so you don't end up with formatted internal sd card
