[Q] xperia z1c lollipop memory leak issue

is current xperia z1c lollipop still have memory leak issue ?
I used lollipop for 2 days already. and it always restart my game (minimized to background) after I open browser to use google (yeah only 2 recent apps displayed. chrome and game apps).
I hate this because my game need long time and heavy bandwidth at loading screen. I never get this problem when I used kitkat. I heard there's xposed module to fix this memory leak issue but my phone isnt rooted.
or is there a way to return to default OS (kitkat) like when I first bought it ? maybe I'll do this way. reset it to kitkat again. but I dont know how.
thanks.

You can flash stock kitkat with flashtool. I should have stock EU . 157 rom somewhere on my pc and can upload it if you want.
Flashing stock rom is pretty easy. Watch a tutorial or something. I can help you a bit more when back home.
Back to your question. I have no idea I'm still running kitkat as L is still not available in my country.

is it working to use your stock rom at my country ? I thought different country have different kind of rom. not sure about this if this is true or not.
flashing stock rom doesnt need root access, right ? and maybe can I also backup current lollipop OS that I have so I can reflash it when it has been fixed ?.
so far what I like from lollipop is when someone call me, I can still use other app because call notification only use small box on top of my current running app. I like this feature very much.

It depends where do you live. If in EU it should be fine. If not I can find a rom good for your location.
No, flashing custom rom does not require rooted device.
I think you don't have to do the backup as you'll be able to just update it again ( at least I think so)

Yes. But you dont have to backup the OS. You can download the Firmware using the XperiaFirm Tool >> http://forum.xda-developers.com/cro...xperifirm-xperia-firmware-downloader-t2834142

is that mean I can flash pre-rooted rom, shared from Xperia Z1 Compact General subforum without unlock bootloader ?
wow then I better use that. I want lollipop+root+xposed but dont want to unlock my bootloader :victory:

wow this is nice info. I've just tried using that xperiafirm tool and it shows my country firmware.

Generally you can root your phone without unlocking bootloader. It worked for me, at least on kitkat. I'm not sure what about the Lollipop though.
You should better ask someone else too as I'm not as experienced and don't want to give you false info.
But if there's pre-rooted rom here and it's working for android L you don't have to unlock bootloader to flash it.

okay I can get lollipop with root+xposed (all day tried this. I read some tutorial how to do it properly because this is my 1st time doing something like this. so tired ). although I dont know if xposed wont work perfectly like you said because I only use 3 modules so far. App Settings (keep screen on for game I'm playing) and Fix Lollipop Memory Leak and gravitybox (LP).
what I've done :
- downloaded kitkat 14.4.A.0.157 from XperiFirm. and flashed it using flashtool.
- I've realized .0157 can't be rooted for now. so I've used your link that you gave (Root FW 14.4.A.0.157 (LB/UBL) ).
- after get root access, then I installed recovery using Z1C-lockeddualrecovery2.8.11-RELEASE.installer.zip from http://nut.xperia-files.com/
- after that I flashed 14.5.A.0.242_CustomizedFR_Pre-Rooted_Dualrecovery 2.8.10 + Fix Xposed for Lollipop using recovery.
- and flashed Massive debloating and Xposed. links and procedure are also from that pre-rooted rom thread.
so far, no bootloop. dont know if I add some xposed modules again. I heard it will get bootloop if too many xposed modules is installed (?)

I have found a way to root stock LP having ULB. http://forum.xda-developers.com/showpost.php?p=60188952
Now going to try xposed. Since you have, tell me how.. Here is the official thread http://forum.xda-developers.com/showthread.php?t=3034811. Is this where you get info?

Xposed worked perfectly in KK. I tried more than five modules at a time without the bootloop issue. What I fear is the LP. Havent you checked the dev/Q&A thread of the modules?
what I've done :
- downloaded kitkat 14.4.A.0.157 from XperiFirm. and flashed it using flashtool.
- I've realized .0157 can't be rooted for now. so I've used your link that you gave (Root FW 14.4.A.0.157 (LB/UBL) ).

wow so much struggle... I have a doubt, why not simply flash that pre-rooted ftf file over the KK? [being lazy to search for the thread]

I dont know that. But I heard that activating some module(s) when some other module(s) is(are) active may cause bootloop in KK.

Hey there, the XperiFirm dev here.
No one answered your question so I will. The answer is: No.
Sony made sure to include the memory leak fix built in (the exact fix that the Xposed module offers) for their Lollipop releases. The Xposed module is pointless.
See attached screenshot. Basically the Xposed module replaces the AOSP function with exactly the same function but with this additional "release()" line. As you can see, Xperia already has this line included.

wow thanks to coming here :victory:
lol. so it's pointless to install that module because they are same thing exactly. time to uninstall.
actually my game is still restarted after I browsing a little. although I still see a lot of free memory in here. before, I thought this is because of that memory leak issue but I'm wrong.
if only there's module that can prevent lollipop refresh/restart/clear my game at memory when I minimized it at background.

I have the same problem, only with audio apps in the background. Pocket Casts, Stitcher and BeyondPod all crash and stop playing when running in the background, after I do something else like load the game Threes. This never used to happen with KitKat. I've also noticed that iplayer radio gets very jerky and skips back and forth by a quarter of a second continuously as soon as I turn off the screen. [edit - I just listened to it for a few minutes with the screen off and it suddenly cut out. I turned the screen on an the app was no longer in my notifications tray]
If Sony fixed this particular memory leak, what's going wrong with my phone? Could it be related to the fact that I've encrypted if for the first time? I'm getting desperate enough to consider factory resetting and losing everything, because listening to podcasts and playing threes is one of my favourite activities. It's not a demanding game for my year old, top of the line phone. My cheap tablet manages it, and so did the phone on KitKat!

[Q] New G3 owner with some questions.

I checked several of the threads in the various subforums but since I am currently really busy (have the phone for 3 weeks and I am not using it cause had no time to check XDA ) if you are kind enough I have some questions that spending more time in the threads would probably answer themselves but alas...
A: If I root the G3 can I bring it back to stock without any indication it got rooted (I heard some phones have special logs that show if a phone has been rooted that survive the various flashes), in case I need to send it for service?
B: Should I go with the root method shown on XDA TV (which doesn't show how to install a custom recovery) or one of the one click auto batch scripts?
C: I think generally this question is not allowed cause it can lead to flame but which ROM would you recommend I try first? I need just a clean, smooth running ROM. Disclaimer: Avoid arguing with other users if you disagree with something they said, just state the ROM and if you want your reason for picking it and I will scroll through them and decide.
Much obliged if you care to answer them and apologies to mods if this breaks any rules.

A: You can always go back to stock using LG flash tool with no evidence of rooting nor like samsung's knox
B: http://forum.xda-developers.com/showthread.php?t=3072767
C: I personally use resurrection remix rom based on CM12 due to performance but if you want fully working G3 with no bugs at all I recommend my favorite rom CupaChups 4.2. Super fast stock base rom with some extra features.
P.S. I recommend you to instal Kernel Adiutor from the play store after you root your G3 and change the governor from default Interactive to Conservative. Cos from some unknown reasons the Interactive governor is bugged on all G3 and changing that will highly increase your performance speed and feel. This works with base and aosp roms also.
Hope this helps
via LG G3 @ Resurrection Remix

Thank you, is there a problem if the phone is already on stock 5.0? Can I still root it with the same methods or must I restore it to 4.4.x? (A simple restore to factory blabla does it?)
Cheers

If you have a look around there's a one click method that works for all G3 variants regardless of software version that is here on the forums. You can use that, download the zip for your desired custom rom, install a custom recovery and then flash the ROM and you should be good to go. There's plenty of guides for you to use, and each custom rom thread should have it's own installation guide

Questions about rooting from a noob.

Hi guys, I'm thinking of buying an LG G4 because it's gotten very cheap now and I want to use it as my daily driver.
I'll be getting the international version and I want to root my phone before properly setting it up. The reason for this is that I want xposed to make some ui changes as I feel the G4's ui is horrible (no offence). I've heard I'll need a custom kernel, twrp recovery, unlocked bootloader and root access.
I've also heard that with custom roms you lose functionality to things such as the IR blaster and the amazing camera app and all its settings. Is that true? If that is the case, I'd rather keep on stock rom with xposed helping me make the UI bearable.
My question is what would I exactly need to do? (with kernels, recovery, bootloaders etc I have only rooted a device once and it was 4 years ago so I have forgotten the basics plus it seems the whole process has become very tough now) The only end product I want is to run the xposed while retaining the IR blaster functionality and the camera app etc.
I have tried going through some videos on youtube but I found them vague, a little different from what I wanted or I saw a few comments talking about how the phone was bricked or stuck in bootloop.

Hi buddy , if your phone comes and it's on lollipop the type in Google " root lg g4 lollipop xda " but if it arrives on marshmallow then type " root lg g4 marshmallow xda " as for losing functions like the IR blaster and camera , I'm using latest Genisys ROM marshmallow version with the Imperium kernel and I have all my features still working they will only stop working if you flash a ROM which isn't based on LG for example Cyanogen or blisspop things like that....
If I have helped please leave a thumbs up!

Hi, thanks for the reply! How is the performance compared to the stock rom? What other benefits does a g4 based rom give?
Also, I still find the process a little confusing. Am I supposed to root first, unlock bootloader or install a recovery. Also what are the chances of bricking my phone?

Well first of all the performance depends there are options when installing different kernels which will give you better speed or better battery life the choices will be written in the kernel or ROMs description , the other benefits are debloated ROMs which means the software on the phone has been reduced to free up space and get rid of useless stuff and other little UI tweaks it just depends which ROM you choose as for the process you unlock your bootloader first via lg devs official site then depending on how you root will depend when you root it I'll explain , if your phone arrives and its on lollipop then use low effort root but if it comes and its on marshmallow then you use systemless root method and I won't bull**** ya pal the chances of messing your phone up is about 30 percent just make sure you follow every single step very carefully , the reason I said 30 percent is because if you're on lollipop then it's easier in my opinion to restore your phone by flashing the .kdz stock file for your phone ( the .kdz will make your phone like you bought it)

What are the advantages of the rom that you're using?
30 percent sounds like a lot, but are you saying that I can restore my phone even if I mess up the process?
Also can you link me to the methods?

The advantages of the ROM I'm using is good battery life with a good balanced performance also it has the LG G5 apps built in to it , and yes you can restore your phone as for the links to the methods I'm chatting to you on my tablet so gathering all the links would be quite hard they are easily found though for example if you are searching for low effort root then just type it in Google followed by xda so it looks like low effort root method xda , if you really want the links then I'll boot up my PC in the morning and I'll find them all for you , it's night time where I am so I'm going to bed soon I'll check your post though in the morning in case you have any more questions and as always please leave a thumbs up I greatly appreciate it , thanks buddy....

No problem mate, I found the link to the low effort btw.
So I'll have to unlock bootloader via the lg website first? then I'll have to install a custom recovery and then root? (or root and then install custom recovery?)
Also I was going through the thread of the rom you're using, and I saw the screenshots and they were pretty much the same as the lg ui (which I'm trying to run away from). Basically what I want is a stock android ui without losing the core functionality like the IR blaster and the camera app, knock code etc.
A question I have is do I have to change the kernel etc while rooting my device or can I just use the stock kernel?

I just did all of these things this morning. I posted my steps here: http://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
I personally stopped installing custom ROMs since Xposed. It lets use keep the phone as it is out of the box but add in just the changes we want. With many custom ROMs, there are always bugs so you'll have to update them and that can mean resetting your device. You then have to install all your apps and settings again.
I tried to make the above guide as noob friendly as possible and it hopefully shouldn't require any reading outside of the thread.

HTC 10 Oreo Battery --> SHOULD I ROOT?

Hello, I am new to XDA and I have an un rooted HTC 10 international unlocked model on software 3.16.401.2. My HTC used to have excellent battery before the Oreo update. I did multiple tests and checks to see what the issue could be and have ruled out rogue apps or hardware issues.
I have never rooted any of my phones before but I am desperate as the battery has tanked so badly
NOW TO THE POINT
I am looking for advice on:
1. If rooting my device and using a custom version of Oreo will actually improve battery issues. (Are there others who rooted for the reason I'm considering, if so did you actually notice an improvement?)
2. If so, what is the safest/most newbie friendly method of me doing this.
PLEASE NOTE: I am very satisfied otherwise with the standard features. I have switched between htc sense launcher and smart launcher but otherwise use the phone very conventionally. I am not opposed to different features but I essentially would like to have as close to what I have now without the battery issues.
(Sorry in advance if there are 100 similar threads I'm already very concerned I'll mess
this up and manage to brick my phone so I am just trying to get clear information in a thread that's not oversaturated and is written in a layman friendly (PLEASE ) way)
Thank you everyone!

1: No, routing your OS won't be the fix for your battery problems.
2: it's the way everybody had to do it, unlock the bootloader, flash TWRP with fastboot and flash a custom rom. It's all explained in the guides section.

Thanks for your response! I am currently doing more research now after reading your helpful comment ?. Would I still be able to use the phones default launcher (HTC sense in my case) after unlocking the bootloader and flashing a custom rom or will every part of the UI now be different?

What about gaining S-Off and reverting to Nougat and Nougat firmware? Seems with all the battery complaints that came along with the Oreo update, there is some validity in asking such a question.

Yes as long as you flash a sense based rom the UI will not change.

You can also downgrade without s-off but it's a bit trickier, there is a dedicated thread in the guides section that covered this. Have a look there for all info, there is also a video in that specific thread that shows how to do it.
https://forum.xda-developers.com/htc-10/how-to/downgrade-problems-downgrading-htc-10-t3735658/page48
But the basic question is also relevant, yes you can gain s-off and downgrade by flashing the firmware and then the ruu or a custom nougat rom.

Which Roms can be installed with QI15 firmware

I have purchased yet another note 4 for the grandson. His firmware is QI15. Original plan was for me to use it, but since my Pixel 3a XL is still yet a lease I might as well use it. Plus it is a lot faster anyway.. His mother does not have the money to buy one for him, so I figured what the hell, he can have it.Which roms can he use.. I no longer have mine, but will root this if it is still possible.. From reading you can't downgrade from MM to LL. But can you downgrade to a earlier version of MM? Thanks.

inYes, that is correct but also cant downgrade the bootloader/modem. That is because of fused 5, binary 4. and te old official stock 5DQ15 .tar md5 can be fashed via Odin. Any other stock firmware below that has a fused 4 and flashing will result in a bricked device.
If your already on 5DQ15 and wish to flash customer roms then use TWRP and make a back up of all partitions to external sd. The any custom rom for Sprint Note 4 (sm-n910p) on Marshmallow are/should compatible. Basically, follow the instructions provided by the rom developer but do not flash a different bootloader or modem. Other than that follow all other institution. For best results, start in setting , sustem update and turm of automatic updates then update PRL and Profile beforehand. Developer Option and usb debugging enabled.
Rooting the Sprint Note 4 on 5DQ15 still possible? Yes 100% SuperSu or Magisk are the preferred root methods.

Also recommend you start with a stock deodexed rom as a base before flashing other custom roms. Rom only

or

then reboot and give it time to properly set up set up. Check if hotspot is visible setting and check your apn settings. If all looks good and it should the return to TWRP and once again make a back up and rename (2019-10-05-deodexStockNoroot.....) so not to be mistaken with any other backups. After that flash root .zip and/or a custum rom of you choice.
I use the BeastMod r61 kernel by Freeza on a N4 Dtux V9 Legend rom. Fixed issues with network connection.

you know what sucks, my last note 4 for Sprint hell I was able to downgrade from marshmallow to lollipop. But since this is for the grandson I guess it really doesn't matter I'll put something on there good for him and leave it at that

I 100% agree that not being able to downgrade sucks big time. I hear all the hipe about new Android OS updates but there are advantages of older versions. In 2018, I searched for a replacement with a lower bootloader but simply couldn't find one. Knowing that peope were bricking there device and Odin fails I decided to get one in fair condition. Being the type to mod and flash yet unsure of what ir how to do that as custom roms are specific to bootloader and modem. I figured, I'll practice with a cheap on incase I hard brick. At the time there didnt seem to be specific information on what rom worked with 5DQ15. I started out with Stockist Plus tidbits Q15. My old Note 4 was on [MOAR v2.1] [ULTIMATE Note5 Hybrid] on lollipop 5.1.1. and had lost of customizations prebuild. So going from the Mother Of All Roms (MOAR) on lollipop to Stockish Q15 on marshmallow, just sucked. It didnt take long before I started taking calculated risks with flashing and porting, even from other models and variations. Stepping out side the box but within boundaries. For instance, the n910f is an international version but much of its software is compatible with the n910p. For instance, this one works on n910p with most stockish roms on Sprint Note 4. With Custum roms it may conflict depending on the setting. If stockish rom or custom rom come with a "rom control"app (interface) and .zip in the link bellow come with "rom control" app thin it is not compatible. One cool feature is it adds "multiple user" in setting.

These n910f worked for me and has the advantage of separate .zips moding specific parts but warn that one of these .zip in the link , I believe its the "settings theme" .zip when flashed removes "hotspot" from the settings. Just 6.0mm zips are compatible on dq15 n010p.

The GRX is one of my favorites for stockish roms. It can be compatible with custom roms but its a complicated process. Im guessing it should work with the N7 hybrid rom. Its relatively easy and offers nice smooth customizations. Its a good idea to chech the setting of both settem and "setting GRX" as to avoid conflict. If you find it on XDA even better. For me, I find it to be the best thing on 6.0mm.

And the PK1 hotspot mod will work as long as the hotspot is in the main settings.

Good luck to you and your grandson rooting and moding.

If you install Busybox with the N7 hybrid kernel I offer a suggestion.

Busybox by Stephen (Stericson)

I never installed the Dr. Ketan rom but I did look at the Touchwiz launcher provided in the .zip and it is a MM. Dont know why you got FC's . Most likely its our latest firmware that to blame.

Wish I could remember what it was I flashed to get that in my settings as I think I remember you wanted that feature.
