[Xperia Z2 Q&A, Help & Troubleshooting] Ned_Flanders:
Ok so I convinced myself that when I got this phone (which is pretty much new) I would not bother rooting and unlocking bootloader etc.

Well I am absolutely fed up with the ads popping up everywhere and so I want to root to get Adaway back (I have it on my Nexus 7 tablet and no ads is a must!) :silly:

so please, what is currently the best and safest way to root? I know it would void the warranty but if I can at least revert it to stock and get the warranty back should anything happen then I would prefer this.

I was reading a few posts that say to root, you need to unlock the bootloader but doing so removes drm keys or something meaning it cannot be restored to complete stock?

Phone is:

Xperia Z2 Black

Android Version: 4.4.4

Baseband Version: 8974-xxxxxxxxx-00027-12

Kernel Version: 3.4.0-perf-gd4d661a

Build Number: 23.0.1.A.0.167

Thanks for your help :)

Backup data

Downgrade to 4.4.2

Root

Install recovery

Flash rooted 4.4.4 zip in recovery

Restore data

You will still have locked bootloader

You will still have warranty

You will still have the ability to return phone to 100% stock state
[Xperia Z2 Q&A, Help & Troubleshooting] Ned_Flanders:
Yeah I remember DoomLord from my Xperia S days :)

Thanks for your help :)

So I need to install the Android SDK and use Flashtool to backup and flash 4.4.2 rom? Also when you say back up data do you mean my music and pics etc, or actually backup the stock rom?
[Xperia Z2 Q&A, Help & Troubleshooting] o0 Matt 0o:
When I say backup I really mean messages and call log. Anything on the phones internal memory that you want to keep. I think I used sms backup +.

And yea flash a 4.4.2 firmware via flashtool.
[Xperia Z2 Q&A, Help & Troubleshooting] Ned_Flanders:
Cool thanks.

One last thing I was looking at the firmwares here: http://xdaforums.com/showthread.php?t=2759934

What do the numbers mean exactly?
[Xperia Z2 Q&A, Help & Troubleshooting] o0 Matt 0o:
Those are the customisation numbers of the ROM. Some roms have different (more or less) stock apps or modified icon. An unbranded rom wouldn't have branded apps like vodaphone app or telstra app
[Xperia Z2 Q&A, Help & Troubleshooting] Ned_Flanders:
Sorry for been a pain again :p

I just setup the android-sdk, adb and fastboot (just rerooted my Xperia S so I know everything is setup ok),

I just want to double check first (better safe than sorry!) before messing around with the Z2:

1. Is there a way of backing up the stock rom and kernel before downgrading to 4.4.2, or do you need root/unlock bootloader to backup?

2. To downgrade to 4.4.2 rom do I just use this command:

I am going to flash this rom: https://drive.google.com/file/d/0B44Yxk18UJ4TNV9jSDlMN0s5NW8/edit

Thanks, really appreciate the help :good:
[Xperia Z2 Q&A, Help & Troubleshooting] Envious_Data:
You use flashtool to flash a FTF file

Fastboot is used for flashing IMGs and elf files
[Xperia Z2 Q&A, Help & Troubleshooting] Ned_Flanders:
Thanks, its been a while doing all this stuff so I just need to be certain.

So I dont need to do anything like unlock bootloader before flashing that downgrade rom?
[Xperia Z2 Q&A, Help & Troubleshooting] Ned_Flanders:
The post i linked to has good instructions I have been following, so I downloaded stock 4.4.2 and 4.4.4 rom, later I will try flashing. I also learned from reading in that thread what all the numbers mean, so in my service menu i was looking at it :) My bootloader can also be unlocked :)

I just want to make sure I do everything right as with my Xperia S and Nexus 7 2013 I rushed into it without backing the roms up, I never bricked the devices but still you do worry especially with expensive phone like Z2 :)

Really helps people who want to help you by describing what caused your issues. Typically though, you'll need to find an RUU from your carrier to flash while in bootloader mode.

Actually I was using this tutorial: http://theunlockr.com/2014/07/15/how-to-unroot-the-htc-desire-816/

My laptop couldn't recognize the phone so I manually rebooted to fastboot, then I entered "fastboot oem relock" and tried to flash but it did NOT work. Now all I have is a bootloader menu. I also tried this but it says that the Hboot version is older. H E L P

What does *** TAMPERED *** even mean though, it's on the top of the screen on the screenshot.
[Desire 816 Q&A, Help & Troubleshooting] FoxyDrew:
The tampered just means that your phone was previously unlocked/rooted.

Follow all the instructions in the second part of THIS thread, making sure to use YOUR RUU file.

If that fails, re-unlock your bootloader, re-flash a custom recovery, and install custom ROM or a backup.

I have to ask, why did you decide to unroot and relock?

Also swearing isn't allowed on the forums in any way, don't try to get around it.
[Desire 816 Q&A, Help & Troubleshooting] exlective:
After it didn't work using CMD, I looked up the thread you linked and what do I see? You saying it should be done with the sdcard method haha, so I tried it that way and it worked. Thanks for all the help Drew.

I wanted to return to stock because of 3 reasons. I might be swapping my phone for an M7, because even though we have to wait till March/April, I do want that sweet, sweeeet Lollipop+Sense update (if the trade doesn't work), and because even though CM11 is stable, I got sick of it. CM12 has some minor bugs that just get on my nerves.

[Xperia Z3 Q&A, Help & Troubleshooting] yafei2011:
I am using t-mobile version sony z3, which as known unlock-able. One thing I really don't like is that on-screen soft keys taking a big space when using apps. I have tried a few soft key toggle apps, like "all in one gesture", immersive mood", I had a ability to hide the soft keys when needed, but keyboard refused to come up when I wanted to type. It was very frustrating. The other thing I noticed was twitter stopped responding when tapping.

Well, all I want to say is that I hope Sony can build this soft key toggle functionality to its own system, just like LG G3. I also really hope I can have the back key to be on my right side, easier for me to tap.

Please support me if you also struggle with this issue if you also happen to have a TMOBILE version Z3. Hope those great developers can hear our voice.

Thanks

+1 I can't for the life of me understand why LG is the only ones able to realize it
[Xperia Z3 Q&A, Help & Troubleshooting] GhostRaiderMX:
I'm using All in One Gestures and yes they keyboard is the only drawback to this great app. However, if you're just gonna read content like news or blogs or whatever, then it works great, especially for Google Chrome. Instagram looks great in immersive mode too. Just swipe down from the status bar to enable/disable immersive mode. When you need keyboard just disable immersive mode with the gestures. If you need the soft key buttons when in immersive mode just swipe from the bottom.

Not sure if Lollipop would fix this problem or if Sony would implement such feature. Using the Xperia's 5.2 inch display to its maximum potential really does make a difference.

TMO's bootloader is NOT locked. Plus the TMO S5 has ALL the LTE bands that AT&T uses plus some additional bands that are TMO specific. So it's a G900A that has an unlocked bootloader and will work on TMO's network. :laugh:

Simple. I put the ROM in my Moto G (1st. gen) and when I flash it, it says "unmount /system; no such volume". I did all the wipes required.

I want to put another ROM and I don't know how to do it, because I formatted everything in my Moto G, the previous ROM, data, cache, etc.

[T-Mobile Samsung Galaxy S 4] serio22:
Sounds like hardware issue. The reason it shuts down is probably as you guess it, safety measure of the kernel. Probably different than what you used or was baked with the older build. Does the phone get hot even when you don't use it?
[T-Mobile Samsung Galaxy S 4] RBalber:
Yeah that's what I'm guessing. As far as the phone getting hot, negative. Phone is cool to touch if it's idle. Even when I turn it on I don't understand how it could be "overheating" The kernel is intersting.... I wonder if I was to flash the newest GPE ROM then flash say KT kernel isntead of the Googey kernel if that would have any affect. I'll give it a shot later. Thanks for the reply.
[T-Mobile Samsung Galaxy S 4] serio22:
That really is odd. Does the battery drain unexplainably?

[Moto X Q&A] IncredibleHulk6:
I've searched and found variations on these questions in other posts, but I didn't come across any pertaining quite to my situation, so I wanted advice before I do something wrong and brick my phone.

I have a Sprint Moto X, unlocked & rooted, running 4.2.2 (I think pre-camera update). I'd like to upgrade to stock Sprint Lollipop (when it comes out) & stay unlocked & rooted.

My understanding of the steps that need to be taken:

1. Unroot my device

2. Re-lock my device

3. Flash TWRP and boot to recovery

4. Flash stock Sprint Lollipop

5. Unlock, then re-root device

Is any of this extraneous, or am I leaving anything out? Do I need to upgrade to KitKat before going to Lollipop?

I also have Xposed installed and I have tweaked the PRL on my device ... this shouldn't complicate the upgrade, right?
[Moto X Q&A] imnuts:
Relocking is useless, and unless you know what you're doing, flashing stock updates in custom recovery shouldn't be done. You don't necessarily need to unroot either, just make sure all stock system files are still in place.

Sent from my Moto X
[Moto X Q&A] dray_jr:
i have a sprint X and if i am going to update this is how i have allways done it with no issues at all.

you can leave your bootloader unlocked that is no a issue. but i always take OTA's and you cant take a OTA with a modded system. so i allways just flash my stock firmware package. that way it removes my custom recovery. Root, and all Xposed changes. Then i take the OTA and just reinstall TWRP, then SuperSU then what ever else you want.

this is the safest way i have found to update, the nice thing about Unlocked Sprint phones is we can easily Root are phones via TWRP and SuperSu.

just my .02 you can do it how ever you like but this is how i am going to do it when the OTA finally comes out if it ever does.
[Moto G General] Semseddin:
Allright,

i am not sure if there's a thread available for this comparison but there had to be one. I post my observations after using gpe 5.0.1 for a month and motorola 5.0.1 using for 3 days. These are my experiences and you're welcome to post yours. I converted my xt1033 to xt1032 to be able to flash gpe firmware and motorola 5.0.1 is the brazil soak ota which is %100 compatible with my device.

Motorola 5.0.1 advantages

- Better battery life

- Better signal and data connectivity ( H+ )

- Faster boot and shut down speed.

- Offline charging works fine, it didn't work well with gpe firmware ( this might be related to my device conversion, not sure. )

- Faster file transfer speed from pc to phone and vice versa.

- Phone run more fluid and ram usage feels better.

- Phone runs cool under heavy load.

- Better camera with HDR support.

- FM Radio is available.

- Native USB OTG support.

- AOSP messaging app is available.

- Games load faster.

- Sound from the speaker and headset is better and louder.

- Better display saturation and touch response.

- Useful motorola apps are available as bonus, can be disabled if not used.

GPE 5.0.1 advantages

A BIG NONE compared to Motorola firmware IMHO.

You're welcome to post your experinces if you used both firmware long enough to make a fair judgement.
[Moto G General] fabus:
So u r saying moto g not-gpe feels snappier and there are no so many laggs? I had been using GPE 5.0.2 and came back to 4.4.4 because of laggy ui...
[Moto G General] donalberto17:
Battery Life is the same in both, Mayor performance differences were in Kitkat, now with ART are almost the same thing cause there is not optimisations in runtime. A advantage from GPE is more space in Flash drive.
[Moto G General] joaofoto:
for the portuguese people (like me) the advantage of gpe is the portuguese language. in the motorola stock we only have the brazilian language
[Moto G General] nirmalbalaji:
I can't make a judgement on Lollipop without using both the firmwares. Moto's firmware is still not finalised! They are still testing it to iron out the bugs and I'm sure it will be even more optimized than the soak test firmwares. On the other side GPe firmware is a stable one.

In KitKat I felt they both are excatly same in performance and smoothness. Battery is slightly better with GPe. Camera department won by Motorola with HDR, slowmotion and overall picture quality.
[Moto G General] Semseddin:

Nice, I can't wait for the Motorola OEM release and your tutorial (IMO it's the best here).

I also prefer, well, I can imagine I will prefer Motorola OEM lollipop instead GPE, I'm a bit confused with some options that are cut in GPE version, mostly camera is the biggest downside of GPE for me. Also some Motorola app functions are quite useful, and system performance is top notch.

But GPE LP is not so tragic though, everything is working as it should, I had no problems with it.
[Moto G General] pfufle:
Thank you! :)

The GPE LP is pretty okay but I am getting that animation stutter when I shut my app drawer and its pretty annoying. Do you face this issue?
