DESCRIPTION
Rom CM12.1 b4 (Lollipop 5.1.1)
This rom works on the following devices:
- Allview P7 Xtreme
- Gionee Elife E7 Mini
- Himax Pure 3
- Symphony Z III
Installation:
- Download Rom
- Go to Custom Recovery
- Do a backup of your present rom
- Wipe Cache/Data/System
- Install ROM CM12.1b4
- Don't Wipe Dalvik Cache!
- Reboot (It may take a while longer than usual. Up to 5 minutes on first boot). Please be patient.
- In the end you will have a fully working Android 5.1.1 Lollipop ROM!
I'm also putting here the last two versions of the ROM.
Remember that on one the camera isn't working while on the other, the camera is working but the network sim cards don't work.
So this is what you do to have a fully working ROM:
- Download both Roms
- Go to Custom Recovery
- Do a backup of your present rom
- Wipe Cache/Data/System
- Install ROM CM12.1 Cam not working.
- Don't Wipe Dalvik Cache!
- Reboot (It may take a while longer than usual. Up to 5 minutes on first boot). Please be patient.
-
In the end you of instalation and when you get to the desktop, do not install any apps yet! You will have to go back to the custom recovery and WITHOUT erasing anything.
Install the CM12.1 ROM Cam working. - Afterwards don't wipe Dalvik Cache and reboot.
- Again it might take a while to converge the two roms, so be patient.
- That's it. You'll have a perfectly Lollipop CM v12.1 ROM working on your Cell Phone.
What's fixed on b4:
- Improved UI
- GPS works great now
- Battery time improved by 10%
- Camera works fine now
- Network signal works ok
Bugs:
- I found none. You let me know if you find any.
P.S. Google Apps (GAPPS) added are "pico" version. (This rom already comes with the google play store, but if by some odd reason you uninstall it, here is the correct version for you to download and reinstall).
All the credits for porting these roms, go out to Septian Aditya.
※Please make a backup of your device before installing or updating ROM
After a couple restarts disabling simcards works just fine.
But now i see that it takes charging much slower. Before this rom was charging at 0.94-0.98 A, now just 0.50-0.55 A on 1 A charger and 0.72 on a 2 A charger.
@rucaxp why do not whipe Dalvik Cache?
It seems that a lot of apps don't work properly.
- gifs are looking strange.
- can't play videos in browser (i have installed flash player)
- audio settings kept crushing every time i played something via walkman
- now walkman crashes everytime i press play.
- sometimes when i receive a call the screen stays black an i can't see who's calling.
- i am able to setup a hotspot but it can't be seen on none of devices
And alot more little things.
Mr @rucaxp, what the hell?!? Did you test whiping Dalvik Cache and it got wierd?
On other hand is very pretty. Works fast. Restored battery life almost to factory specs. I think the slow charging, that i was complaining about in the earlier post, did the trick. Also a couple of full charges and discharges.
I tent to congradulate you @rucaxp on the work, but i beg you to help us improve this rom. I mean you to improve the rom. Thanks man!
I don't have time for this now. Got to study.
But anyways, thank you for clear up a few things for the rest of us.
Although I have to remind you that the "b4" stands for BETA v4. As in a Test version.
Dalvik Cache must not be erased because there has been problems using Lollipop. People seem to lose all their photos or other data.
That is why I wrote it. Don't ask me why. I didn't built the fucking Android Operating System. Google did.
Camera work, but all the camera recorder apps was error: "camera in use…." . I use HD Camera Ultimate to record video, but it dont work. Can you please fix it
Does HD Camera has Lollipop 5.1.1 support?
Yes, I installed it by Google Play, I search on Google Play some more camera recorder apps and test, but none of them work
use manual camera..:)
Can you share a video of the procedure..last time it was stuck
Just installed it and the device doesn't seem to recognize my sim cards – simply no sim error message – any suggestion pls!!
My device was stolen. And therefor I have no means to help you people.
First chance I've got, I am moving to Mars. Planet Earth is full of thieves!!
voice to text and voice msgs (in whatsapp, hike, etc) are not working else it is just fine!..sometimes simcards get unstable but for a while. i just change the rom than ;P
and ya, GPS is good now but it sucks during navigation activated in maps
if you will please fix these 3 things, i will be gratefull to you.. else i need to discart my phone
I've uploaded two old ROMs. Go check it out and follow the intructions to the letter!
This will be my final help on this phone. Since I don't own it anymore.
Take care.
thanks
