You can only manually change the backup name. I believe new backups taken in TWRP are the correct time. I dont use TWRP though so this is all "on the grapevine" stuff

Twrp now has the correct date for the backups...

i just purchased a htc one max from y sprint carrier. ill save the long storys.

i rooted it just fine from what i could tell. unlocked it as well. the i tried flashing skydragon on it, and it seems it reduced the functionality. so naturally i didnt back anything up. and tried to remove it, or tried to flash another rom. can remember honestly its been a long two days trying to get this thing to at least back to factory. and so now the end result. there is no OS. the bootloader is still flashed to non stock with s on. and everytime i try to flash a rom it fails. tried adb sideload and that failed. tried the onclick factory reset. that fails. so far htc guru gets the furthest. it runs all the way through the installer gets to the end. and when it reboots it says no os installed. so im at a loss. my last ditch effort is gonna be just bring it back or smash it and claim insurance replacement.

any ideas would be fantastic
[HTC One Max] FunkEIzMyName:
Not to experienced on this side either but I have a good sense if development. Have you tried running rumrunner to get s-off. It sounds like you will need to be s-off. Also which custom recovery are you using?
[HTC One Max] pradeepvizz:
Look for sprint RUU, i am not sure if that is around, that should get you back on business.
[HTC One Max] sirbrixalot:
i think i tried rumrunner. i dont recall. ive tried so much stuff its all a blur.ill have to go back and try again to be sure and im using the team win flashed recovery.
[HTC One Max] sirbrixalot:
i tried to look for a sprint ruu and the one i found was corrupt. go ****ing figure. any suggestions where i might find one?
[HTC One Max] pradeepvizz:
how do you say it's corrupt, have you heard of an encrypted RUU?

Is the most helpfull forum ive ever found! Its just the greatest! All knowledge everyone shares THANK YOU
[Lenovo K900] duo_m:
i want to replace the stock sms app on my k900 with go sms pro. how do i do this? i've already checked in the go sms app that it be the default messaging app but i still get double sms notifications and the stock sms app is still active. i can't find anything in the system or messaging settings that would normally turn off the notifications for the stock sms app just like in my past htc's and xperias.

any help would be greatly appreciated.
[Lenovo K900] mikey199:
In the messaging setting you can turn off auto message checking and popup windows and notifications. I haven't tried but I think that should work. Goodluck
[Lenovo K900] duo_m:
i already did all of that but still i get double notifications and messages. it seems that the system still prioritizes the stock sms app over a 3rd party one despite having the 3rd party app be explicitly the default SMS app. i've had partial success with textra. i still get notifications from the stock sms app but at least not a double message and i could just ignore the unopened text messages from the stock app until i have to open them at a later time. but i still wish there was a way of totally replacing the stock sms app. this app seems to be bundled/attached to the dialer and contacts app instead of it being separate and only able to "talk" to the dialer and contacts app. seems lenovo doesn't want the user to install any other app that tries to replace the ones that lenovo put in place. for shame in this.

in any case, this'll be my first AND last lenovo phone. i've been badly burned by this very simple yet intolerable (for me) experience. i think this goes against the android ethos of being "open" considering it's a "goolge" android OS.
[Lenovo K900] duo_m:
can this problem be solved by rooting the phone?
[Lenovo K900] X0LARIUM:
No. The only way is to hard remove the app from the system/app folder. But you will be doing that on your own and at your own risk. It's not recommended..

Sent from iCeborg's iPad.
[Lenovo K900] duo_m:
Ouch! Will putting the much talked about vibe rom possibly solve this issue?
[Lenovo K900] X0LARIUM:
Don't think so..its how OSs work I think..I may be wrong.

Coded from a Clover Trail+ Machine!
[Lenovo K900] duo_m:
Found a simpler solution it's almost stupid. It was staring at me the whole time. Went to settings>apps>contact manager. Unchecked notifications then pushed force stop and then disable. Replacd my dialer/contact manager with go contacts ex. Now, I'm happy. Didn't have to go through the mess of rooting and flashing a custom rom.
[Lenovo K900] X0LARIUM:
Good to hear that.
[Lenovo K900] karellang:
Try add new contact. Works? Probably no. If you want add new contact, you must enable contact manager again and disable after adding. A little uncomfortable. Do not delete contact manager (ideafriend) from system/app!

ist for dialer, contacts, SMS messaging and call log. The unfortunate solution. unfortunately. :(
[Lenovo K900] duo_m:
it's quite the opposite everything's working fine. go contacts replaced the stock contacts manager flawlessly. i already added 2 contacts and edited more than half a dozen old ones. received and made phone calls without a hitch. like the old lenovo contacts manager never existed in the 1st place! now i can use my k900 with much more tolerance until i could to sell it ASAP and get me back to an xperia.
[Lenovo K900] karellang:
Interesting. When I unchecked Show notifications, press the Force Stop and Disable in Settings / Apps / All, calling through third-party application goes normally (tested to Go contacts and Ex dialer), but using these applications not join a new contact, I can not edit an existing contact. It just goes through the built-in Contact Manager. The same if I add a contact via SMS third-party application (for example Go SMS Pro).
[Lenovo K900] duo_m:
Really? Hasn't happened to me yet (unable to edit) I'm using go contacts pro as my dialer and contact manager. Like i said before, i added and edited contacts without problems. Hmmm...
[Lenovo K900] karellang:
Go Contacts pro doesn´t work on 4.3. I try without Go Launcher, with Go launcher and nothing.
[LG Optimus 4X HD] peppethustra:
Hi guys!! I was thinking about opening a thread where everyone can specify what's the better kernel setup, according to her/his own necessities, and share that configuration with all p880 community. Also, it can be submitted the relationship between the kernel and the ROM an user is running on the device, to compare performances and make each other more conscious about kernel tweaking. I think it's better to open it in general section, so everyone can write, without being scared by submitting something not related to developing.

This thread won't to be in any way a substitute of the "Battery life!" thread, so if anyone wants to post specifical results or screenshots about battery duration, please post them here:

http://xdaforums.com/showthread.php?t=2478514

Said that, the idea is to post a message like this:

KERNEL: name of the kernel you are using

ROM: the name of the ROM you are running

SETTINGS: the kind of settings you applied to your kernel (example: Governor=interactive, Scheduler=Sio, Multicore Power Saving=2,CPUquiet=balanced, LP Core uV=-15 mV, MPU uC=+20, and so on)

GOOD: the benefits you experienced with your configuration (the more specific possible)

BAD: the badness you experienced with your configuration

Of course, if the thread begins to grow up, is recommended to read everything before posting a configuration too much similar to another which have been posted yet.

If you think this is a good idea, press thanks, if you want, and let's begin posting, otherwise report it to moderators, like [MENTION=4716493]laufersteppenwolf[/MENTION], and they will close this thread as soon as possible :)

If someone like [MENTION=4582979]JoinTheRealms[/MENTION] is interested to, I'd appreciate very much to create a section dedicated to the scripts, as a second post of the thread, maintained and refreshed by the author.. Let me know, and take your own space here, if you think it's good for you! :D
[LG Optimus 4X HD] peppethustra:
So, I'm starting posting my own last configurations:

1)

KERNEL: iodak v9.95

ROM: Beanstalk 4.4.2

SETTINGS: Governor=interactive, Scheduler=Sio, CPU max speed undercloked to 1300 Mhz, CPU max screen off frequency=370 Mhz, Multicore Power Saving=1 ,CPUquiet=balanced, LP Core uV=-30 mV all frequencies, MPU uV=-75 mV all frequencies

GOOD: this configuration improve battery life, without decreasing overall smoothness - suggested to the users who don't mainly use the phone for hard gaming and want to find a compromise between battery durability and overall performance

BAD: some little lags, here and there, randomly happen - I suggest to apply underclock, before changing cpu freq voltage, because this configuration is good for 1300 Mhz undercloked device, but it may cause system freezes on some cpu variants, if you set cpu clock up to 1600-1700 Mhz (tested)

2)

KERNEL: iodak v10

ROM: Beanstalk 4.4.4

SETTINGS: Governor=interactive, Scheduler=Sio, CPU max speed undercloked to 1300 Mhz, CPU max screen off frequency=620 Mhz, Multicore Power Saving=1 ,CPUquiet=balanced, LP Core uV=-100 mV all frequencies, MPU uV=-100 mV all frequencies

This configuration is very battery friendly, more than the last one I was using on iodak v9.95. Nothing is slowing down, btw ;)

[MENTION=4582979]JoinTheRealms[/MENTION] reserve a post to yourself, if you liked my idea to dedicate some space to scripts explaining :)
[LG Optimus 4X HD] JoinTheRealms:
Saved!
[LG Optimus 4X HD] PenguinStyle:
Lol, I'm using almost the same config.

Kernel: Iodak 9.9.5

Rom: Beanstalk 4.4.2

Settings: I haven't changed anything

Good: Very fluid and stable

Bad: battery life, Antutu 3D test score
[LG Optimus 4X HD] KrisJoe:
Kernel: 9.95

Rom: CM11 official

Settings: Max Frequency 1150 Mhz Cpu governor:interactive

mpu undervolt -100 on every freq (cpu variant 2, some hangs while waking the smartphone and I need to tap on the screen sometimes, if I press the power button the device won't wake up anymore until I restart it).

Congestion: westwood

Cpu quiet: runnable

Cpu max screen off freq: 475 Mhz

Good: less heat, more battery life, smooth experience

Bad: If I put 1300 Mhz as max freq the battery life will decrease.. And without 1300 Mhz as max freq I feel like cutting this smartphone's cpu potential.

Still bad battery life even with these tweaks, still disappointed, but so far this is my best configuration with Cm11 official.
[LG Optimus 4X HD] JoinTheRealms:
The scripts i posted earlier, really shouldn't be take too seriously, mainly because they are written for ubuntu and require input. But when i get some time ill modify my post and give some examples of init.d scripts, or more specifically, the commands inside them. That should be somewhat more helpful i guess;)
[LG Optimus 4X HD] peppethustra:
Take the time you need, the thread seems beginning to live, so we'll read your post for sure, when you will bring it to evolution! :D
[LG Optimus 4X HD] KrisJoe:
Kernel: Optimus Play v2.53

Rom: CM11 official

Settings: Max frequency 1200 Mhz (sometimes I tried to put it at 1100 Mhz or even lower, 1000 Mhz, resulting in better battery life)

Congestion: cubic (since there's no westwood implementation in this kernel)

Cpu quiet: not implemented (I think it's put on runnable or balanced as standard)

Cpu governor: interactive

Multi-core battery saving: 1

Gpu frequency scaling: on

Good: awesome perfomances, the games and all the apps are very smooth and compared to the earlier configuration with iodak v9.95, this is very much better, but be aware that I'm trying to have perfomances and battery life balanced, and on iodak v9.95 I undervolted the cpu of -100mv resulting in some cases of hangs and crashes. Battery life is still good, but a bit worse than the iodak configuration.

Bad: Battery life's not very good, it goes harder on deep sleep when the display's off, iodak v9.95 is the best with deep sleep; in fact it takes a while before entering that state, it usually stays on low frequencies but it still consumes the battery.

An other aspect I noticed is that even when the smartphone is on charge, when I'm using it, it doesn't charge much, if ever it looses energy, which is explained by the very good performances of this kernel.

A small bug present in this kernel, and not in iodak, you usually need to double press the power button to wake the smartphone, but it's much better than risking to have your smartphone crashed while waking it up.

Overall: A very good kernel for performances, I don't know if it's the best but it's very good, battery life's "good" if not using the smartphone, otherwise it drains quite fast, I think faster than the undervolted configuration with iodak.

If you're looking for smoothness with games and apps I'd suggest this kernel, if you prefer battery life I'd suggest iodak more, but I remind you the hang problems on it if you decide to undervolt up to -100mv.

I tested both kernels with the same Rom and apps and use more or less, so I'm quite positive it's a good test.

I hope it helps and you can give us tips or suggestions to improve this smartphone's battery life, without losing perfomance. I think this is the thread's goal.

and yeah, every LG Optimus 4x hd possessor's dream is to have a good battery life so well, let's help each other and get the best out from this device, it's not **** yet in my opinion, it just really has a bad battery usage.
[LG Optimus 4X HD] peppethustra:
[MENTION=4783744]KrisJoe[/MENTION] Very good review! I hope many people will follow your example..comparing user's kernel usage and customizations is the better way to help everyone to find the needed configuration, and to let them make whatever they want, with their phone, on the best possible way
[LG Optimus 4X HD] KrisJoe:
I just noticed something going back at iodak v9.95 to try peppe's configuration; on iodak v9.95 the temperature of the cpu is higher, there's a difference of at least 20° C more or less. Problem was that I went back to iodak because charging with optimus play v2.53 was a pain since instead of charging it wasn't. (Of course I mean while in use)

With iodak charging is flawless (I activated the fast charge option, which isn't present in Optimus Play).

Is it because of the fast charging option that's making the difference?

I'n trying the cpu undervolted by -75mv MPU and -30mv LPU, and it seems a bit laggier than the optimus play one, I can feel the difference just typing with the keyboard on the browser, but it's charging despite me using the smartphone.

What do you think it's the cause of the slow charge in optimus? And maybe more important thing, how is it possible that the cpu has a 20° C of difference between optimus and iodak but I keep the same frequency? I even undervolted with iodak, and in theory it should be the opposite situation, with iodak having lower temperature.
[LG Optimus 4X HD] peppethustra:
So, talking about charging, on iodak's kernel you have to consider two situations: if you are charging through USB port, you may experiment slow charging and battery consumption even while charging, if you use the phone in the meanwhile (so, using fast charge solves the problem, but it is recommended to do not use it too many often, if you want your battery to have a longer life)..the problem doesn't exist if you charge the phone through AC adapter, so the phone should charge at a normal speed, even if you use it, whit no fast charge necessity.

Talking about my configuration, yes, you may have some little lags, here and there, 'cause this is a battery saving configuration, more than a gaming performance one.. ;)

Finally, temperature: maybe the difference between the kernels is due to a different overall cpu voltage, or the temperature is not really precisely shown, honestly I don' t know for sure :)
[LG Optimus 4X HD] KrisJoe:
I'm using the ac adapter and with optimus play charging was a bit hard and slower than with iodak. With -75mv it seems I don't have problems with waking up the smartphone and it seems a bit smoother, maybe a placebo effect, but I think that it could be the limit of undervolting with variant 2 cpus.

Now that I didn't use the smartphone for while the temperature is lower (49-51° C), the high temperature was due to the 1500 Mhz used at the beginning because I deleted cache and dalvik before installing iodak again (to avoid problems). Let's see how it behaves in these days, but I'm a bit confident iodak's config is better for battery saving, even though with antutu benchmark I did 13000 with iodak and, and 12800 with optimus play (with battery saving and performance balanced). It may be a wrong test but I still wanted to give it a try.
[LG Optimus 4X HD] peppethustra:
Yep, I tried to uV MPU frequencies at -100 mV, and it freezed my phone, after some seconds or minutes..so, I also think CPU variant 0x2 has this uV limit..maybe it's possible to uV a bit more single frequencies, without causing freezes, but I had not the time to try to individually uV any single frequency :)
[LG Optimus 4X HD] KrisJoe:
I was thinking that we should specify what runtime we're using, if Dalvik or ART because I actually felt some differencies. What about you? Do you feel any difference with using one or an other? Sorry for the off topic, but I thought we could talk about the runtime also since we'll looking for the best performance/battery life.

O.T.: Don't activate ART Runtime on the latest cm nightly (3rd of April 2014), it will force close some apps like uicall, dialer, ecc. I had to return to dalvik by installing an older version in which ART was working... quite unconvenient.
[LG Optimus 4X HD] XxXDarknessXxX:
This is the best thread ever guys.

I am using iodak 9.95 in Zaiben RC8.

Max 1000 mzh, interactive, no undervolting, Multi core savings 2

The only bad thing is that if i want to wake a the device it doesn't wakes for the first time and I have to press twice the power button.
[LG Optimus 4X HD] peppethustra:
Yes, everyone is free to talk about ART or Dalvik, of course, it's related to Rom customization, using or not using it! :) Personally, I'm not using ART, considering it's on an early, experimental stage, and I have no time to switch between the two runtimes, if something should go wrong with ART (I need this phone as my really daily driver, and I haven't too much time to experiment, ATM).. But every single accurate review, also explaining how runtimes work, with a specifical kernel and a specifical Rom, is appreciated here! :)
[LG Optimus 4X HD] peppethustra:
Try multicore powersaving=1, and a little undervolt, you should have benefits in terms of smoothness, without losing battery ;)
[LG Optimus 4X HD] ottomanhero:
KERNEL: Iodak 9.5 (I know 9.95 is newest but I prefer 9.5 as I think it's performance/battery ratio is better.)

ROM: CM 03/30 nightly

SETTINGS(variant1): CPU max: 1500 lowest freq.: 620 screen off max: 475. GPU freq max: 564 mhz

MPU undervolted by -122 mV and LP core undervolted by -10mV but lowest freq. voltage is on default and max freq is on 1230 mV due to 564 mhz GPU freq. ART enabled and Multicore powersaving is set to 2.

GOOD: A lot smoother than 9.95 and with these undervolting I've done, it can survive heavy gaming without throttling.I can say this setup is the best for gaming if you've got variant 1.

BAD: Battery life is a bit worse compared to stock kernel.But with ART enabled it's difficult to notice the difference.Plus if you underclock to 1300 mhz your phone will still be smooth while giving you better battery life.
[LG Optimus 4X HD] CrazyWinner:
I have double press to wake bug with iodak 9.5 how did you solve it ?
[LG Optimus 4X HD] ottomanhero:
I use volume rocker to wake the phone up as a workaround.Easy to reach it with your midfinger once you have the phone in your hand.Plus you get to press the power button less, extending it's life.

Edit : Incase you didn't know official CM and most of the custom ROMs have volume rocker wake option in settings > button or under some other category.
[LG Optimus 4X HD] TheFerhatKing:
Very good for my battery thanks for this setting :)!
[LG Optimus 4X HD] peppethustra:
You are welcome! ;D
[LG Optimus 4X HD] Captain Sisko:
Not sure how you pimp a kernal!! the only thing I did to mine was change from stock to Optimus Prime and Optimus Play

How do you customise clocks and things?
[LG Optimus 4X HD] peppethustra:
You can set all the parameters described in previous posts using scripts, or using an app like trickster mod.. you can find it on Google play store
[LG Optimus 4X HD] Captain Sisko:
I downloaded Trickster and am running EternityProject Kernal

Freq lock to max 1200000, min 714000 and governor set to conservative

Still getting used to the pimping
[LG Optimus 4X HD] EnQeen:
Guys what is the best rom + kernel ? I mean i need the fastest one and stable , smooth , i dont really play games and I dont care about battery life. I just dont wanna have bugs + freeze form tiem to time.

p.s. I use CyanFox rom with iodak 9.5 kernel
[LG Optimus 4X HD] peppethustra:
There is not a sure answer for that..everyone should try roms and kernels, to find what is the better combination according to his/her own necessities.. Read the post before yours, in this thread, and you'll find some reviews..then, read the ROM and kernel threads, and you will find other infos about pros and cons.. Everyone, here gave a try to many stuff, before choosing his own settings and configurations :)
[LG Optimus 4X HD] EnQeen:
Well, I have tried a lot of stuff, and don't feel real difference between them. Also people has different mind about each kernel + Rom combination. I need the fastest and stable one, maybe someone know what I need
[LG Optimus 4X HD] Androidmarketuser:
I'm using a little bit modified config from peppethustras second post which saves battery while remaining the stability.

So I'd really recommend you the latest Beanstalk NB (if you don't care that recording isn't possible without fix, for me NB version is faster and more stable) in combination with iodaks kernel. Unfortunately there aren't any tips for other kernels, as the others haven't been updated for a longer time and could contan issues like no deepsleep.

You want performance and stability, but you don't care about battery life:

io scheduler to sio

min frequency to 102000, max to 1600000, max screen off to 620000

raise gpu max freq a bit

cpuquiet to userspace, 4 active cpus (look at this: https://android.googlesource.com/kernel/tegra/+/android-tegra-3.10/drivers/cpuquiet/Kconfig)

undervolt a bit, not too much as it will cause instability in combination with overclocking cpu and gpu

Edit: I'm not quite sure whether the gpu overclock will stick, there were discussions about it in the beanstalk thread, maybe someone else knows about that?
[LG Optimus 4X HD] peppethustra:
Regarding gpu clock and scaling, there are some issues with last beanstalk NB build and iodak kernel, we were talking about it with [MENTION=5047403]ottomanhero[/MENTION] on beanstalk thread :)
[LG Optimus 4X HD] EnQeen:
so what is the most stable ROM today ? I think iodak kernel is the best solution for me :3

What do you think about Official CM ? or OmniRom ?
[LG Optimus 4X HD] Androidmarketuser:
For me it's propably Beanstalk. I tried many roms, including CM and OmniROM, but all had frequency issues (occasionally freq was set to 100mhz) except BeanStalk. But these issues should be gone by now, KK roms aren't in an early stage anymore.

If you want real and guaranteed stability there are only the stable Cyanogenmod builds (CM10.1.3 based on Android 4.2.2).

I'd recommend you to try out Beanstalk and if it's not stable enough for you, you should use a rom marked as stable.
[LG Optimus 4X HD] EnQeen:
Okay. And what is "NB" ?
