How do I do a proper clean flash? - Elephone P8000

I am currently experiencing severe battery drainage(would drop suddenly drop from 50% to 5 within an hours of NO USAGE) and I am no longer able to send sms texts but I am able to receive them. Other than these issues phone is working fine.(using eragon 6.1)
I think these issues are caused by me dirtyflashing the phone. First from stock>nexus>eragon 5.5>restored 6.1
Can any one help me flash eragon 6.1 straight to my phone without going through stock?

If you use philz recovery you have the option to wipe to flash a new rom. As for the battery drop I have had this before on stock and custom roms. I just made the battery die completely then fully charged it and after 2 cycles it was fine.

[Q] Can't revert back to stock ROM: Battery level too low

I have an annoying problem. Im currently runnin Supernova ROM, which has proven to be as unstable as early AMD CPUs and I have been trying to get to the original rom running the RUUxxx.exe. Problem is that the RUU flasher refuses to work because it things the battery level is below 30% (which actually is 90%). I have tried pretty much everything from wiping the battery stats and installing another rom after which I tried to install stock rom. It's a no go.
Anyone got any ideas how to go back to stock? Or do I just need to flash some other 'stock' rom made by a forum member?
P.S. I have tried with another battery as well.
Have you tried a Battery Calibration.
try battery caliberation.

[Q] [Help] Random Reboots

Hi, I've been suffering some random reboots (about 3 per battery cycle) and after every reboot battery goes down drastically. I've changed the ROM and kernel and it still happens. I attach a photo of the battery life (you can see when the 3 reboots happened in the interruptions of the graphic) and a catlog (it's my first catlog so I'm not sure what to do). If you need any more info or the previous part of the log just tell me and I'll provide it.
Mine is a GSM gNEx and now I'm on Rootbox ROM (31/01/13 version) with ak 670.42 dummy kernel but as I said, it also happened in CM 10.1, AOKP, PA and with ak purity, leankernel and franco kernel.
Thanks in advance and sorry for my english.
it could very well be the phone itself. i had something similar happen on my toroplus and havent had the problem since i replaced it.
It could be your chip, but let's look at a couple of things first.
1) Are you dirty flashing by any chance?
2) Have you gone 100% stock and see if it happens there?
Nope, I haven't tried 100% stock, will try tomorrow (after doing my last exam of my degree). Also I've just had a reboot at 82% battery and the first one yesterday was at 82-81%. Is it a coincidence or can it be a hint? Maybe it's the battery...
Also I've been doing a full wipe between ROMS, no dirty flashing except for upgrades on the same ROM (just upgraded rootbox to latest JOP40G)

Well I would do 100% stock boot, recovery, ROM etc... and see what it does.
I doubt it's your battery.
My random reboots stopped after I stopped flashing custom kernels. Try a clean install and keep the kernel that came with the ROM and see if you still get them.
Thanks, then tomorrow I'll try going back to stock ROM + kernel and see if it gets solved, if not I'll try with full stock.

[Q] Problem with Omega 12 + Perseus 33.3 start up screen lasts forever

HI Guys
I'm an old iOS user but switched to android 2 months ago with a wonderful Note 2 International running android 4.1.1
​
after one month of use I decided to root my device for VPN service and custom ROM benefits
​
Everything went fine. First rooted with odin 3.07, then decided as most of users recommended to flash ARHD 11.2
After using my device for 2 weeks I noticed poorer battery performance. 4 days ago, After a lot of searching online I decided to flash Omega 12 then Perseus 33.3 for better battery performance and better control of my CPU.
That's what I did. First, wiped all data through CWM then installed Omega 12 ---> Perseus 33.3 ---> clean cached data ----> restored my apps through titanium ----> fixed permissions ---> charged my mobile to 100% then wiped battery stats ---> set gpu to 440mhz and cpu scaling --> frequency responsiveness to 600mhz === every thing went very good with wonderful performance and battery life with 40 hours battery life ,more than 7 hours onscreen and also did couple of successful restarts to change SIM card .I thought that's it "I will stick with this system forever no matter what."
:highfive::highfive::highfive::highfive:​
As I said, after 40 hours of battery life my battery died so I put my note 2 with the recharger while off because it was night time. Next morning, I unplugged my phone then turned it on but my startup screen keep showing the big robot walking with no ending for 30 minutes. Tried to restart the phone couple times, searched online for a similar issue but nothing related to omega and Perseus, wiped cache, dalvik but still the same.
:crying::crying::crying::crying:​
Finally, I restored an image through CMV contains my 4.1.1 old stoke ROM + factory kernel just after rooting. My smartphone now is working fine.
My question now is "Why did it happened? Did this happen with anybody before with the same circumstances? and what is the possibility of this happening again if I tried to flash a custom ROM or a new kernel?
I'm ready for any questions​

Firstly, NEVER let you battery die completly, it is not good for the overall life of the battery.
Secondly if that ever happens boot to recovery and clear dalvik cache and fix permissions. This will usually help.
It's hard to say exactly what cause this issue without a log.
Also, please keep regular backups through your preferred recovery, as this will help if you need to go back.
Cheers,
Evil.
Thanks for the tips.... really appreciated

same
same thing happened to me exactly .
same rom same kernel
i couldnt even restore a previous backup of omega from a week ago - it just wouldnt restore without rebooting !!
also, for my note 2 to work again i had to reflash my recovery (twrp) via odin and reinstall my rom.
i had a whole load of other issues and in all honesty im almost thinking i may have a broken NAND chip - sudden death - not quite, but im patched for that, but may be a small fail on the chip had caused this event , i really dont know.
im back to normal now but im stll very worried about the next few days - please read my other post where i explained this fault at the time it happened.

thanks.
.
I will look at it... but I think in the mean time I will stick with my original stock and kernel for a while till I have the courage for another rom/kernel trial

Battery issues

Hello, I've switched ROMs from lollipop back to KK ROM. Its not stock, its cm 11. 4.4.4. I flashed the madmack modem. But my battery life has still been horrible since leaving lollipop. Is there anything I can do to get it like it used to be?
What is used to be like? What ROM were you using? It is recommended to flash into custom ROM while begin with the stock jb ROM, if you want the best battery life.
Go to apps from.the settings and from there see what applications are running and try to close (force stop) every application that u dont need and i think it will solve ur issue
Or just install an app like greenify. I'm with you on the battery issue. Even though my service is getting the deep sleep, I'm still need to swap a new battery every 3 - 4 hours, and that's with normal use, keep the screen on most of time. I think it's just our phone, the 5.5" HD screen just ducks up all the juice.

Check with some battery stats software, but it's 101% problem with SystemServiceUpdate. KK CM11 isn't patched for that.
If that appears to be the problem, go to privacy manager and disable wakeup for Google Play Services and Google Play Framework/Google Services Framework, reboot your phone and wait.

Boot loop issue when battery dies or on abrupt restart

I'm running stock 5.1.1 rooted. Whenever the battery dies on the tablet, it will go into a bootloop when I charge it and turn it back on (gets to Samsung logo with no start up music). So far, that only thing that seems to work is wiping data. Has anyone experienced something similar? Bad install maybe?
I've had the same thing happen to me last night. I tried everything and nothing worked. I had to restore a old back up i had with twrp and it started fine. Not sure what causes it though.
I've been having this problem for 6 months now. Let me try a custom rom.

Update the twrp tp latest version.I had the ame problem with old twrp but now all is fine with 3.0.2.0.
mine just started doing this. i can boot into recovery but the touch screen doesn't respond. i can also get into odin. I believe i was running Rooted Stock 5.1.1. Should i just reflash (i was thinking of going custom like LineAge) or do i need to reflash stock rom? I was also reading about just flashing the PIT and EFS. i know it's a 3 year old tablet at this point, but it's been good to me and i'd like to increase my odds of bringing it back to life
