New CM12.1 ROM from BetaHydri for LeTV 1 Pro US

[jerzyjerzy]

When I plug in my Sandisk OTG Usb drive, it doesn't pop up when I use the default file manager, but after I installed the Es file manager it works normally.
Try to use ES file manager.

Thanks!

You are absolutely right about it!

I uninstalled the USB OTG Helper and ES everything worked as it should. Thanks

Hi to everyone!

Thanks betahydri for your rom, it's well made, fast and very usable.

I've found this bugs, i'd like to share with you and with others to see if there is a soluzion.

1. Camera App = slower than the stock rom camera in shooting photos and problems with aspect ration in the video (4k preview is wrong, recorded video is ok; 1080p and 720p right in preview but saved video with wrong aspect ratio - for all the tree quality is not the best) > Maybe I can use a different camera app?! Why not LeTV Camera app?

2. In settings > Advanced Settings the label is not translated

3. Sometimes happens that connecting the charging cable the mobile won't charge: solution is to shout off or restart the mobile (I've your rom from 2 days and i've had this problem 2-3 times! - obiously i've tried different cables and power supplies)

BTW, OTG also works with Total Commander, only the "USB-Stick Plugin TC" is required for that.
With the plugin installed, Total Commander recognizes the pendrive correctly (plain Total Commander does not).

Weird brightness issues. I don't like adaptive brightness so I have it off.
When I put the phone to sleep and wake it up the screen is dim but the brightness slider hasn't moved.

If I use auto brightness the screen doesn't go dim, but it stays at the same brightness all the time regardless of the conditions. Also moving the slider does nothing with auto brightness on

I installed 4.2 on my second phone. These same applications, even a few less. Observing the battery after a night on the phone first loss of 4% in the second 31%. For the latter, even wifi was turned off. What could be causing this?

Hi JAXS71,

please use my biuld-prop: http://forum.xda-developers.com/attachment.php?attachmentid=3895856&d=1475748616
And put it on your second LeTv and give me feedback. I'm testing this one for now 2 days and the power saving should be better.
--> I put my LeTV at night to flight mode and switch WLAN back on. With this combo my LeTV went from 100% to 92% in those nights. So try it and give feedback ! Thanks !

Hi BetaHydri.
I have to unzip the file and replace the existing in directory system?

Hi BetaHydri.

Yep exactly the original in /system must be replaced. BTW I have done a dalvik + cache wipe after replacing it.

Ok Build.prop swapped. Then wipe the phone and... standing on the start screen

That's strange as for me it works perfectly. Did you second phone came from a factory reset directly to V4.2 ?
As this is excatly how my phone was setup and then I swapped the build.prop file with File Explorer EX and wiped only both caches in the advanced wipe menu then rebooted.
I have done changes inside the build.prop regarding: Memory HEAP, Dalvik Cache, dexopts and WLAN Scan interval.

For now I must say it runs smoothly. Battery is better and since 2 days no crashes like black screen, blue LED, Power Button not turning on Handset. Those crashes were related to the DALVIK cache and its crappy optimizations that I didn't touched yet. That's the reason why I changed also the dexopts to be more strict with the verify parameters:

• dalvik.vm.dexopt-flags [USEFUL*FOR*ALL DEVICES]
• This property can change the behaviour of how Dalvik VM performs optimizations and verification. There are various settings you can use, setting “v=n” will turn off the bytecode verification v=y will turn on the bytecode verification and setting “m=y” will turn on register map for tracking objects to garbage collect. Setting these properties can help you free up unused objects and free up more ram.

Also dalvik.vm.execution-mode=int:jit was implemented again:

• dalvik.vm.execution-mode [USEFUL*FOR*ALL DEVICES]
• Setting this property to int:jit can help you achieve some performance gains in your system.

If some others can confirm that this build.prop runs well, I will change it inside the ROM V4.2 and upload the updated package again !

I tried twice. Your rom is very good. How do you modify a file build.prop in it certainly will not hesitate to install it.

Hi,

coming from the Cuco92 ROM I wanted something new so I tried your ROM.

However, the cell reception is much worse. My secondary SIM rarely connects, at work not at all where it could connect with full bars on Cucou92. The primary SIM also is more often on H+ instead of LTE, and transmission rates are slower. (I especially know becaus I play Clash Royale on the toilet haha)

Any ideas?

You can copy the original build.prop file from my 4.2 ROM and compare the settings via notepad++ compare addin with the new one. Then you can change the values that differs directly with ES Explorer editor on your handset.

Question: Do you have installed the Xposed Framework or any other side loaded apps.? I'm asking as my dalvik deoxopt flags have the flag v=y maybe you could try v=n!

Self tweaks on some network settings inside build.prop

Hi,

coming from the Cuco92 ROM I wanted something new so I tried your ROM.

The primary SIM also is more often on H+ instead of LTE, and transmission rates are slower. (I especially know becaus I play Clash Royale on the toilet haha)

You could play with following settings in my new build prop and also try the know key combo to select you preferred network with: * # * # 4636 # * # *

• ro.telephony.default_network=22,22
• ro.ril.def.preffered.network=10

So the above means then according the list below:

1. default Network for SIM1, SIM2 = Unknown
2. preffered Network for SIM1 = LTE/GSM/CDMA auto (prl)

--> so this means you can try for your SIM2 ro.ril.def.preffered.network = 10,10
or whatever your preffered network is in your country !

Networks according to the LIST from hidden telephone menu (aka * # * # 4636 # * # *)
0 = WCDMA preferred
1 = GSM only
2 = WCDMA only
3 = GSM auto (prl)
4 = CDMA auto (prl)
5 = CDMA only
6 = EvDo only
7 = GSM/CDMA auto (prl)
8 = LTE/CDMA auto (prl)
9 = LTE/GSM auto (prl)
10 = LTE/GSM/CDMA auto (prl)
11 = LTE only
12 = LTE/WCDMA
13 = TD-SCDMA only
14 = TD-SCDMA and WCDMA
15 = TD-SCDMA and LTE
16 = TD-SCDMA, GSM and LTE
17 = TD-SCDMA, GSM/CDMA
18 = TD-SCDMA, WCDMA and LTE
19 = TD-SCDMA, GSM/WCDMA and LTE
20 = TD-SCDMA, GSM/WCDMA , CDMA and EvDo
21 = TD-SCDMA, LTE, CDMA, Evo GSM/WCDMA
22 = Unkown

You can also tweak and remove the # inside my new build.prop that I pasted as download on the first page.

# Better internet browsing & download speed
#net.tcp.buffersize.default=4096,87380,256960,4096, 16384,256960
#net.tcp.buffersize.wifi=4096,87380,256960,4096,163 84,256960
#net.tcp.buffersize.umts=4096,87380,256960,4096,163 84,256960
#net.tcp.buffersize.gprs=4096,87380,256960,4096,163 84,256960
#net.tcp.buffersize.edge=4096,87380,256960,4096,163 84,256960
#net.tcp.buffersize.hspa=6144,87380,524288,6144,163 84,262144

#net.tcp.buffersize.evdo_b=6144,87380,1048576,6144, 87380,1048576

So i just installed the new v4.2 version and i can't get LightFlow to work now. It was working flawless in previous version. I did a clean install with wipes and everything. Anyone got this issue?

L.E: Never mind, i got it working.

 

[BetaHydri]

I also had Problems with beeing stuck in 2G/GSM Mode with SIM 2.

I think i found the Problem in the built.prop.

There is no preffered Network Type configured for Sim 2.

I use a 3G Card in Sim 2 Slot. For me the following changes worked (i added a the last ', 20' in the following lines asuming that if it Works for me for Sim1 it will also work with Sim2 with the same card)

ro.telephony.default_network=22,22
ro.ril.def.preffered.network=20,20

Depending on your Network you might need some other Entry.

I have a Germany Vodafone 3G Card. For me this works perfect.
Maybe someone can give me some hints where to find a Definition of those codes

Thank you, Master. I'll be installing
