To root or not to root - Huawei P9 Questions & Answers

Hi! First time posting here so do forgive me if I make any mistakes.
I've been thinking if I should root my P9 or just do a full reset as it seems to be lagging ALOT nowadays and I have warranty untill end of 2018.
I've rooted my older phones before but I'm not sure whether I should for this so do advice me thanks!
Oh and I was also wondering if it affects the camera and battery life after rooting or using a custom rom?
Model : EVA-L19
Build Number : EVA-L19C20B386
EMUI Version : 5.0
Android Version : 7.0

Custom roms are complete trash for this phone. So many bugs and half baked stuff. If you care about camera, battery - never put a custom rom. Root why? What do you want to do? I don't see a point of rooting nowadays.
Just hard reset it if it's lagging. Will make it like new. And it's that simple.

Clear the cache regularly AND setting animation scale to 0.5 are 2 things that can easily be done to help eliminate lag and poor performance.

[i9000] Complete Android Noob.

Right, ive had a i9000 for 5 months or so, and ever since i got it, ive found it to be slow, at times laggy. And hate alot of the crap samsung put on it.Which ive not even used.
I reckon its about time i start to make the most of my phone, but dont really know where to start, with these custom roms and rooting and what not.
I basically want it to run smoothly and possibly add a tweaks/features to it which could possibly improve it. However i remember reading somewhere, that ill lose the camera features if i install a custom rom. :l (i could be talking from my arse here)
Also i read that android 4.0 is coming or has come out. Would i be able to upgrade my phone to it ? and should i ?? If not what is the best rom to flash which will make my phone faster and smoother.
Is there anything at all to make it significantly faster, or is it limited by hardware :/
Im currently on:
kernal version 2.6.29
firmware 2.1 -update1
Which i havnt messed with since i got the phone.
Thanks, and sorry for the daft questions.
Oh dear! did you wrote 2.1? Please read basic root steps and install custom rom. I recommend you to start with Cf-root

As far as 4.0, please wait.

OK, here we go...
1. First of all you need to root your device to install a custom rom or kernel. So first root your device with the above thread (cf-root).
2. Choose any rom from so many roms available all over xda. Choose only from the topic which is under your device's category, not from other device's rom,lol.
To do this you need Odin(use search)
3. Once done you will have custom rom and also custom kernel if you wish.
After these you can go for lagfix, like changing from rfs to ext4.
Best of luck.
Thanks, so after ive rooted with cf-root. do i have to install a custom rom and custom kernel, both ?
And which is considered the best rom and kernel ?
thanks

Hey Skweezer,
Recommend you start with these threads:

They will tell you about how to connect your phone to your PC (Samsung USB drivers + adb), 3 button mode (how to avoid bricking your phone), backing up important/unrecoverable data (like your EFS block!), and what (in general) needs to be done to flash custom firmware.
After that, you should be able to pretty much recover from any error (like unplugging your phone mid flash). Now you can go ahead and root your phone and start exploring the wonderful word of custom roms! As for which one is the best, that's like asking "how long is a piece of string?" Some people prefer speed and cutting edge, others value battery life and stability, some aim for the middle of the road.
Personally I've tried tegrak kernel and was really impressed with the speed improvement! However, the limited app space finally turned me back to other kernels. I found the rest to be pretty much six in one, half dozen in the other (ie all about the same)... so pick one you like and just go for it... use it for a while and if it's not to your liking, flash again
Just a quick rundown on android for you... firmware 2.1 = Eclair, 2.2 = Frozen Yoghurt, 2.3 = Gingerbread, 3.0 = Honeycomb (tablet only version of android) and 4.0 = Ice Cream Sandwich (unify android for phone/tablet/tv again). There is a HUGE performance increase from going stock 2.1 to 2.3! so even if you just upgrade to Samsung's Gingerbread release (2.3.3 I believe?) you will notice better performance. Doing lagfix, kernel tweaks, etc is just icing on top of the cake. However, you'll find once you start tweaking, you won't go back to stock
Well, easiest way of starting is installing KIES and letting it update your phone. That's the official way and you won't have to bother with details like kernels, roms, bootloaders, etc and won't void your warranty (if that's the case).
You'll probably be left with with some 2.3.x version. Might as well make a backup from your stuff before upgrading, kies sucks in a general way, but may help you with that.
From that point on, if you still want to press further into customization goodness, there are PLENTY to chose from.
There are mainly 2 kinds of roms:
- Samsung based (someone picks up a sock samsung rom and modifies it with scripts, kernels, themes, apps, etc). These are most of the ones you'll find in the development section of this forum.
- not samsung based (like Cyanogen e MIUI). These are built from Google's sources directly and totally skip samsung. Therefore, samsung apps most likely won't work here. Everything else does.
Personally i'd recommend Cyanogen 7.1 stable as your next rom. It's an extremely optimized and wildly popular rom, with plenty of options that you won't find in any stock rom. They have their own forum i recommend you to look up if you're going their way.
Whatever you do, GET AWAY FROM THAT 2.1
Cheers for alll the replies guys. Im first going to just update via kies. To an official 2.3
If im not happy with that then ill try a custom rom and rooting.
If only it was as simple as jailbreaking and iphone. lool
Right, ust updated to latest version via kies. And instantly alot better, smoother. Has some of those things bulit into the system which i always though were missing.
Ill try it for a week, and see if theres anything i need, or think is missing. Then i might go custom. But right now im happy with it on the latest official version.
Thank you guys, i think you've made me sort of like android a bit more.

[Q] Wich software is the most stable for Galaxy S i9000

Hi everyone,as you can see in the title i have a simple question for all of you .
Wich software is the most stable for Galaxy S i9000 ( No lag,no random restarts when you're running a app and stuff like this )
If someone know and its simple to put the software its free to give me a tutorial how to do this . My curent version of android is 2.3.6 Baseband Version i9000XXJVT, Kernel Version 2.6.35.7-i9000XWJVZ-CL762604,Build Number GINGERBREAD.XWJVZ.
IM noob on rooting flashing so...help me if u can
I'd suggest Darkyrom.com, it's a VERY noob friendly rom, stable, fast, great battery life and it has it's own forum so you'll definitely get support for problems. and flashing their roms is a simple one step process (for the base roms) or a few steps for a full rom (read on their forum for the differences) and as long as you follow their step by step instructions (which they provide) you needn't do any preparation work like be pre-rooted, their rom roots your phone and does everything for you.
Rooting is necessary for pretty much all android customization if you were wondering
If you want to upgrade from a better rom after that, you're all set to go what with having flashed their rom, but they have great roms so you may not even want to.
If you want to upgrade to a better rom, one which is faster, or has better battery life or can do something else better, then you'll have to look through threads here on XDA and figure out which is best for you yourself. But reading details on the rom and other people's experiences can really help. Just take other people's experiences with a pinch of salt, unless a problem is being experienced by almost EVERYONE it's usually a one off... other people's problems may not be yours
Agree on darky if you wanna get GB ROM

Ics scaring me

If you are running stock ICS(which I'm sure you are) you should assume that you are affected by the bug.
Refrain from doing factory reset using the STOCK/CWM recovery as this will trigger the bug even on STOCK recovery. If you have CWM do not do a NANDROID RESTORE.
If you are rooted i suggest flashing a safe custom kernel, a good one that I can
recommend for solid battery life and balanced performance is Speedmod k3-3 just look for it on the development section.
If you don't like custom kernels and prefer stock just do not do the ones I've mentioned above. If you really need to do a factory reset do it on Gingerbread.
Regarding the battery life, there are many factors to consider. First thing that you need to check if your phone is going into deep sleep. Download cpuspy on play store and report back here so we can help you.
HOLY CRAPPPPPP
Well i have already done the FACTORY RESET 2 times but now its working fine so far
So what should i do now?????????????????????????
Also i would like to know if i can switch back to gingerbread os using Skies software?????????????????
You cant use Kies but Id recommend using ODIN because its faster and safer.
Check out dr.ketans guide http://forum.xda-developers.com/showthread.php?t=1424997, the man is a genius.
His English isnt great, but essentially
Download ODIN
Download whichever stock rom you want (GB)
Set phone to download mode
Connect to Odin
and flash.
His instructions are a lot more detailed (maybe to much so). But if you do this, the dangerous kernel will be gone and youll be safe.
I know where you are coming from being fairly new to the android scene. Have been in it now for about six months and i would consider myself fairly literate. From what you were saying you updated your phone to the official ics version for your phone. Well... The first thing you need to do my friend is read, read, and read some more. Alot of what i know and have learned has been from researching these forums and the web. Rootgalaxynote.com is pretty good for noobs as it usually has videos showing you how to do things step by step but you should also read some of the faq's about rooting and flashing on this site. If i were in your shoes the first thing that i would do would be the following;
1.) root the device using Dr. Keetans method on this site. If you havent done this it wouuld be a good place to egt started. His method will not trigger your phones counter.
2.) I would revert the phone back to its earlier version which would be gingerbread. You can do this by looking in the stock gingerbread roms section under android development on this site. Our fellow senior members have made it fairly easy to find and after reading you should have a pretty good idea of what to do.
3.) Install a kernel that is safe for ics roms such as franco kernel or abyssnote kernel. This should be fairly easy for you to do just make sure you do tue steps exactly as they describe or else you will mess the phone up.
4.) After that you can pick out a custom ics rom which if you are looking for optimal battery consumption this would be the best way to go about it as official ics rom consumes a substantial amount more battery than the sleak, lean more refined custom roms out there. Just be carefull what you choose as some are full of bugs and features not working.
The main thing here is to cover alot of ground and do your homework. Research is key and you always want to stick with sites like xda and a few others. Xda may not be the most user friendly site out there but it contains a wealth of information and iw where the best of the best come together. Hope this helps my friend.

If you can still run it fine, then you're good. But from now on refrain from doing things on the recovery until you're on a safe kernel. Some users reported that they were able to do a factory reset to the nth time before encountering the brick. Meaning you can factory reset 999 times and get away with it and on the 1000th time, brick ur device seriously god knows when it will happen.
Just stay away from CWM or Stock recovery for now if you don't know what you're doing just to be safe.
P.S. ICS is nothing to be scared of if you know what you're doing. Do a little research about the hardbrick bug good place
to start reading about it is this POST
Well i completely agree with you mate and i need to do a lot of homework before i make any change.However since i am very new to the terminology used in ANDROID so would like to ask you if there is any website which can explain me a lil bit about these terminologies so that i know what everbody is talking about or is it that i should simply go through the forums and then join all the bits and pieces to get an idea about the terms used.
Also i would like to ask you that "ODIN" is it like another software which is used to flash the FIRMWARE

hmm. website... ? well you can start on this website http://developer.android.com/about/index.html and don't forget our ever loved website.. (XDA-DEV)...
Just by snooping, hanging around, munch and digest all you can and soon you'll be able to pick some neat tricks in learning android terminologies in no time at all.
ODIN (PC /Mobile) is a very neat indispensable tool for custom room makers and flashers... With this tool you can always at your disposal.. whilst jump from one custom rom to another, which ever your choice or liking. Changing ROMS is akin to Flashing.. so if you flash a ROM, you are changing your current ROM to whatever ROM you would like to have it installed on your phone.
Every custom ROM has its highlights and lowlights... pick what suits you best and your good to go after. Flashing ROMs with Gingerbread support (if your still in stock GB), assures you no brick at all... Now on the other hand, if your already in ICS(Stock) and would like to flash custom roms with iCS support.. then I do warn you to be wary of it. A lot of people have fallen and have been bitten by the hardbrick bug... Just always be extra careful in doing it.
Cheers bud!
First of all i really thank everyone for their help considering that i am a noob when it comes to android
2ndly i am alos getting an impression that Gingerbread is a better bet as of now till there is a permanent fix for the Bug and secondly i am getting an impression that GB was much better when it comes to the battery backup
Correct me if i am wrong
Alos a clarification
Stock rom means the firmware from SAMSUNG?Am i correct?
Custom rom means that it has been tweaked to avoid any known issues?Am i correct?
Also if i change from custom to stock riom does that hamper the warrenty or not?

Yes! Flash it back to Stock Rom and unroot it. You should be good to go.
You should not worry too much about the bricking bug. If you stay on stock rom and your phone gets bricked you are covered by the warranty. It is not your fault that the phone has that problem.
I also recommend that you ask some friend that has experience to help if you want to flash/root/install custom rom, given that you have little experience with android.
i have just checked in and found this link "Root Your Phone"
This means he is going back to a particular version
Right?

Dilpreet,
U remind me of myself 2 years back when I was equally inquisitive, enthusiastic but lacking knowledge...
First of all... There is no problem whatsoever if you remain on stock(yes u r right official) Samsung ics provided you don't do factory reset ahead.
2. U need to familiarize yourself with android terminology such as rooting, flashing custom (yes again u r right tweaked) roms, recovery mode, download mode, full wipe, Odin, directly/not directly root able roms etc etc... I am not trying to psyche you out but just giving a word of caution. Unless you know all of these terminologies well (you will get lot of reading on xda on each of this) , PLEASE DO NOT ATTEMPT ANYTHING. By anything I mean even reverting to GB. U must have updated from GB to iCS OTA (over the air) that is on device itself but this rversal won't be easy unless u fully know what u r doing... so first familiarize urself and then get into it.
3. As regards battery life on stock ics , you can use app named juice defender (available on play store) it has lot of options for battery saving. Besides check if GPS and wifi options are not switched on when not in use... some apps are battery hoggers. Check battery usage under settings ---- battery to see how its doing.
4. There are few safe ics kernels available like what has been told u before by some people in this thread... I would strongly suggest Cm9 or any cm9 based rom like asylum (btw Cm stands for cyanogenmod ) which are smooth and safe & yes extremely battery efficient too.
5. Lastly, I will pm you one apk file which will help you know whether your phone has a brick bug or not... do uninstall that application after you check it. For installing any external app (apk file) you need to go in settings ---- security --- and tick unknown sources
PS: Do click Thanks if I have been of any help mate
Sent from my GT-N7000 using xda app-developers app
Nopes... rooting is gaining administrator rights over your phone. In simple terms , being able to access system folder on your phone... Beware, rooting voids warranty.. Please refer Dr. ketan's guide on rooting note on other thread... That's best

". Lastly, I will pm you one apk file which will help you know whether your phone has a brick bug or not... do uninstall that application after you check it. For installing any external app (apk file) you need to go in settings ---- security --- and tick unknown sources:"
Thanks for the info mate
And i have already checked the article which helps you to check if your handset is affected or not and what i could understand was that we just have to install the application and then run the application and will generate a result
But what after that?
I mean how ill i come to know which files to look for which will tell us if its affected or not
I am not aware as to which all files to look for
Please help me
It will throw up the result after checking.. u need not look for anything... it will tell u if ur phone is prone to brick bug.. check it urself. Have sent u the apk file already through pm (personal message).
This will just tell you if you are really prone to this bug, nothing beyond that. If you are then you have three options:
1. Stick to stock ics rom but don't do full wipe again
2. Revert to stock GB through Odin
3. Switch to safe ics kernel (and enjoy lovely ics experience without boring Samsung touchwiz)
For the last you will have to root your phone for remaining, rooting not required.
PS: Please press Thanks button if I have helped you anyway

[Q] Installing clean HTC version

Hello guys!
So I bought my One two days ago and I'm pretty satafied with it , but the Rom that came along the device is the vodafone one , which means I have some unnecessary pre-installed apps..
So my question is how can I install a clean stock Rom ?
In addition , I experienced some things I didn't really like such as pretty bad battery life (losing about 1% after using whatsapp for a minute or even less - pretty much the same battery life I had while using my previous 3 year old sgs1) , and a little stutter while using apps like fb,youtube,play music or the camera .. Do you think that changing the Rom can fix those problems ?
Thanks in advance !

Yes, a custom rom and/or kernel can fix those issues. You need to unlock (I think via HTC Dev is the only way at the moment), flash a custom recovery (CWM or TWRP, I use TWRP and recommend it), root, and flash a custom rom (some Roms come per-rooted so you may be able to skip rooting yourself). There are toolkits available in the Development forum, as well as guides to help you out. Read, read, read, and choose the method you're comfortable with. Roms close to stock, but that allow removing the bloat are Maximus and ARHD (both close to stock). I use ViperOne, a Sense rom with an insane amount of customization! Custom kernels can give you some added features that can help battery life and reduce lag. I use ElementalX and really like it. It's all here in the forums, just read, make backups, and read some more. Hoped this helps...
