A few questions about /unlocking bootloader/custom recovery/rooting - G4 Q&A, Help & Troubleshooting

Hello,
I´m pretty new to rooting and all of that. I know how to root my LG G4 (LG-H815) but I have a few nooby questions. And I´m sorry if they were answered elsewhere, I couldnt find them.
1:
When unlocking the bootloader, the DRM protection of your phone will become untrusted.
Some applications which require DRM protection may not work anymore or block certain functions due to this untrusted DRM.
Common examples are applications which offer download/streaming of paid multimedia content like music and movies.

So does that mean I can´t use Spotify and Netflix when I unlocked the bootloader?
2: Is there a way to completly unroot and uninstall the custom recovery to install OTA updates again? Is it possible to update with LG Bridge with root installed?
3: My last question: Is there any Website for LG stock firmware (like SamMobile) I already found lgkdz.com but when I enter my IMEI it doesn´t show me any results.
Have a nice day.
(Sorry for my bad english)

[Q] Uninstall Chinese keyboard and other apps

Hi Guys,
I recently got my Xperia Arc, and I love it, however it has a Chinese keyboard app on it, amongst others (Let's Golf, youku etc) and I cannpt uninstall them via the applications section.
All options are greyed out and there is no uninstall option regardless.
Is there anyway to get rid of these?
Thanks
PLEASE use the search feature first. It's there for a reason.
Anyway, you need to root your phone. Install Titanium Backup and you'll be able to remove all the unwanted stuff from your phone.
Once again, please do use the search. It'll help you to answer the questions which you've got after reading this reply. LOL!
Thanks for the reply and suggestion.
I did search, however it was most likely far too specific.
Furthermore, I understand I have to root the phone before I can use Titanium backup.
Is this a risk, can it brick the phone? Is it illegal to do so? Is this the equivilent of a iphone jailbreak?
I don't want to do anything illegal, I just want to get rid of some apps that are annoying.
vaibhavknockout answered all your question. Its the first topic in Xperia Arc General forum!
http://forum.xda-developers.com/showthread.php?t=1133650
urgh I am confused about it all.
I don't know if I want to risk doing it, I still don't understand it.
Basically I want to get rid of the chinese apps.
I have an Xperia Arc with 2.3.3.
I live in Australia but have the Hong Kong version of the phone.
I understand I can unlock it via bootloader and I will need to root it to be able to install Titanium Backup which will uninstall the apps.
But can I just install the UK or Global image/rom and that will load it as if I got the phone from the UK/Global?
Rooting your phone isn't illegal nor is it going to void your warranty. You don't have to unlock the bootloader for rooting.
Do refer to [Guide] All in one 'Namaste guide' to Bootloader unlocking, Rooting, Flashing & more.
You can flash a generic 2.3.2 ROM (or UK if you prefer), then root using Gingerbreak and then upgrade OTA (Over The Air) to the 2.3.3 ROM and you'll still retain root.
Using Gingerbreak is simple and straight forward. Do note that Gingerbreak won't work on 2.3.3 and hence the need to root on 2.3.2 and then update OTA to 2.3.3 and still retain root.
There's a free version of Titanium Backup on the market. It requires root access to work. And it should help you get rid of the stuff which you don't require.
Hope this helps! And LOL! Use the thanks button to show your gratitude

[Q] Rooting AT&T Xperia Play (r800at)?

Hi,
Can someone please write a noob's guide to rooting the AT&T xperia play (r800at)? The phone is carrier locked and bootloader locked. Is there a easy way to just get root permissions on the stock AT&T rom (2.3.3) without unlocking bootloader? All I want to do is remove AT&T apps which I don't use and free up internal memory (I only have 40 mb left). I couldn't find a thread which clearly explains this (have been searching for more than a week now).
PS: This is my first android phone, so I don't have a very good idea about how all this works.
Thanks.

You are basically in the same place i was in a few weeks ago.
First off let me link you this this thread
(http://forum.xda-developers.com/showthread.php?t=1270295)
You'll find there that you cannot currently root the r800at without first unlocking the bootloader!
The bad news is that unlocking the bootloader is the the most difficult part
here is the bootloader unlock guide by Alejandrissimo.
(http://forum.xda-developers.com/showthread.php?t=1232050)
Its a pain in the butt on this particular phone so i highly recommend you have Alejandrissimo remote support you. Be prepared to pay 24 bucks for the unlock since the software requires it either way.
If you have Alejandrissimo help you he will also install the CWM recovery for you.
THIS is important as it installs a custom recovery mode for your phone that you will use to backup your phone, install kernels, and ROOT your phone.
If you are going the DIY route here is the Clockwork Recovery thread
(http://forum.xda-developers.com/showthread.php?t=1130639)
I hope this helps. After all the hard stuff is done the rest is pretty easy. Learning how to put your phone into recovery is important into jumping into all the other great things you can do with your phone.
The first like has an excellent post by xSoNiCcRaCkErSx who has basically tested many of the custom rom/kernel combinations on the r800at!
I hope this helps you and all the other r800at users out there!
Thanks DrROBschiz
From what I have read, [unlocking bootloader + applying clockwork recovery patch + Over-the-air updates] can brick the xperia play. Is this true? Have you tried OTA updates?
Also, I found another method (but I am not sure if it works with r800at). You flash 2.3.2 firmware using tools from wotanserver (cannot paste link because I am a new user). Then use gingerbreak to obtain root (this should work because of downgrading to 2.3.2) and update with OTA to get the latest version of android (claimed to retain root on the latest version). This method also doesn't seem to need unlocked bootloader.
Has someone with AT&T xperia play (r800at) tried the second method?
Also curious, can you unlock the bootloader via the process from Sony on their official site (which I cant link to right now)? Is there a downside outside of not having help (which don't get me wrong may be needed)
@8-Bit: You cannot unlock bootloader following Sony's website if you have carrier locked phone (r800at is locked to AT&T US). When I tried that, I realized that carried locked phones are not 'fastboot' enabled. Also, sim unlocking the phone using 'unlock codes' won't enable 'fastboot'. It will just make the phone capable of accepting other networks sim cards.
Also yes its important to note that if your bootloader is unlocked OTA will brick the phone.
MAKE A BACKUP!
I understand not wanting to deal with the complicated process of the current unlock method but it really is the only viable option for the AT&T version of the Play unfortunately.
I finally have root!!!

I tried the second method. It works. But you do loose the AT&T branding (phone will be identified as r800a/r800i based on which ROM you flash). Also, when connected to mobile data it says "H" instead of "H+", though I didn't notice any difference in data speeds.
@8-Bit: if you need any details, I would be glad to help.
I just did this today. Started with stock 2.3.3 on an r800at. I used Wotanserver ( which is currently free for some reason) to flash to 2.32 as an r800a model. Then I installed gingerbreak. I now have root including wireless hotspot!
The only gotcha was I needed to load gingerbreak via my pc, a direct API download from the web would not work.
My speeds are fine as verified on speed test.org and I was able to get back to 2.3.3. Over the air.
Phone is much faster and has much more memory due to the Att bloatware being gone.
Give it a try!
Will doing this enable fastboot so you can unlock the bootloader and install custom roms?

Were you talking about the Wotanserver method? I'm not sure how it works it's magic. I think the boot loader probably was unlocked to ge the firmware on but then re locked. At least I hope so because my hope is to get thE 2.3.4 OTA update on somehow
I believe the att, and firmware update supports 4g, hence when you flash it to generic you lose that... But it's speed difference between really fast and really faster.. So it's not even noticeable. Personally I believe it's better if the phone is rooted and bloats removed.

Ok guys I told a friend I'd help him get rooted. And ive been reading here and im lost.. From what I gather. The bootloader on the att version is locked and to gain root. That needs to be unlocked.. This is where I'm lost. Why is the best method to go through someone else. What does that involve? Sorry to sound dumb I'm just really lost here. haha.

If you just want root then go to wontanserver and register and download driver and client software and follow their directions. Choose r800a 2.3.2 (3.0.A.2.184) . Now use gingerbreak1.2 (search forums) and follow direction. Now update over the air only. You have rooted 2.3.3 r800a enjoy
Okay, so I'm having problems with my phone randomly not getting a signal ever since doing this method... is there currently any way to go back to AT&T stock? Also, has anybody else been having signal issues? It says I have bars, but I can't call/text and I have to restart the phone. Very irritating.

Hi... first off all, sorry my bad english
If you have locked bootloader (SIM-locked) and want to root whitout unlocking bootloader, try this:
"Working Root on 2.3.3 locked bootloaders! (Works on all Xperia Plays except R800X)"
http://forum.xda-developers.com/showthread.php?t=1116090
Worked like a charm form me...
Portugal - TMN
Xperia Play R800i locked bootloader.
Gingerbreak worked very fast for me, BUT only after turning off Wifi connections and UN-plugging the USB-cable
Have froozen lots off app's (think is the correct term) with Titanium backup
Have used Link2SD to move other apps to SDcard
When I bouthg the phone it cames with 2.3.2. I made the mistake OTA upgrading before reading about root.
At beggining (2.3.2) the phone boot, from startup to PIN code, about 3-5 minutes.
After OTA upgrade (2.3.3) i noticed some diferences (about 2 minutes to boot)...
After rooting phone MAKES BOOT IN 45 SECONDS!!! (from begining to PIN CODE)
Always have about 250mb ram free
Internal storage 150mb free (Im still afraid of using Insecure ADB to move dalvik cache to SD)...
I read lots of pages on XDA forum to know about rooting and all the benefits&risk's involved, and root related tools, before rooting so advise all the others newbies like me, doing the same
Thanks to all make this possible (must thanks here because I dont have post permission in develoment area)...
Once again, thanks a lot...

It might be a late reply, but it might still help some one. I had similar problems (mainly with data connectivity). I fixed it by adding APN profiles for AT&T under settings >> wireless & network setting >> Mobile networks >> Access Point Names. Let me know if you need the details of the APN profile.
guys im having the same problem, i got a friend who needs helps with his xperia play at&t, he wants to unlock the bootloader, and install a custom os, i was looking for the 1st option on the first page, but the link doesnt works anymore, any suggestion?

If he was anything like me, then he searched, searched, searched, and after that, searched some more. Superoneclick does not work for our phones. All the guides for xperia plays don't mention a damn thing about rolling back firmware from version 2.3.3 to 2.3.2 in order to root. I was loosing my mind trying to figure this out at the time; tried multiple PCs/multiple USB ports, thought maybe my syntax was wrong on the manual methods so I tried a couple of automated methods like superoneclick and DoomLord Root, when those didn't work I thought maybe the drivers weren't quite right so I investigated that issue for ages but couldn't find any more up to date ones than the ones I was using. I then tried messing with a few automated rooters right from my phone like z4root and Gingerbreak which didn't work either. Finally I found this thread(same one linked a couple of posts up) which did the trick (I have it saved in my favorites). It's not missing any steps and is accurate to the T. Worked for me the first time and didn't require any special hexes, voodoo, or rain dances.
I just checked and since that thread is so old, the links are now dead. I would post there, but I'm not allowed (developer's thread). Here are some links to the software needed:
Flashtool
Android 2.3.2 (.184 as referred to in that thread)
And finally Gingerbreak v1.2 - should download this from your phone and install to it's internal memory (not the SD card) prior to flashing
The other methods of rooting may have worked once downgraded to 2.3.2, but I just followed that guide and used Gingerbreak as it seemed the simplest way.

[Q] Unbloat Z1c running KK 4.4.2 (14.3.A.0.681)

I bought a simfree Z1c, updated it to 4.4.2 when sony released it and got sick of all the bloat that comes with the phone. I searched the internets and forums to find a method to unbloat this phone without voiding warranty. From what I understand I should:
1. root the phone
2. uninstall all the crap i detest (FB and YT and other "social" stuff that makes me behave antisocially)
3. ???
4. profit!!
(optional 5. unroot it so I don't make any accidental changes after I my phone is cleansed)
I've been having problems with #1, that is a root method for a phone with locked bootloader (to retain warranty) running latest android from sony (unbranded 14.3.A.0.681). Is there a way to do this without downgrading OS, unlocking bootloader, etc.? A link to proper HOWTO would be more than enough...

If you are only interested on eliminating bloatware, there is a way of hiding it without being root... in configuration/apps the ones that can not be uninstalled can be disabled, it will not eliminate them but will disable so they will not run in background and also will not appear in apps menu,

Read the link you've already read, if there was an easier way it would be posted, as it isn't, and if you can't or don't want to unlock the bootloader then you'll have to downgrade first.
Sweet. Disabling apps will do just fine until a root for KK comes out. Thanks!

H815 rooting questions

Hello,
I have had my G4 H815 locked to UKEE for a good few months now and I have been holding off on rooting as the official way of unlocking the bootloader I believe breaks the DRM keys and it was hinted that there was a small possibility than a nicer way may come about. It's not looking like that at the moment and I am now clucking to get my root apps and freedom back.
I have had and HTC Desire, Samsung S2 and Xperia Z1 all rooted many times and flashing multiple different things etc so I am by no means new to rooting but I am not a technological whizz kid and looking at the root methods for this, as with every new phone it seems, rooting methods are getting more difficult. My questions are;
1. Can anyone tell me what they have experienced not working when the bootloader gets unlocked? I understand it may just be video streaming? Can anyone confirm the likes of Netflix etc won't work? Any other apps / ill effects? I assume YouTube still works? I currently use Barclays banking app, that didn't work on old phone while that was rooted, I'm assuming with the bootloader unlocked it will never work again on G4?
2. Is Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks the best root method to use? Or is it, as I guess [ROOT] TMO/VZW/ATT/SPRINT/INTL Root your LG G4 with Low Effort Root! the best to use? Or is there another you suggest that is easier / better / harder to destroy my phone?
3. Slightly O/T but being on EE they are extremely stingy with updates so I am still running 10C, I have seen about FW up to 10H or more. Is there somewhere that has the change logs of these different firmwares?
"I believe breaks the DRM keys"
This is true for the Sony Xperia devices, but not really for others that I know (Samsung S6 and HTC M9 included). I have unlocked the device on day 2, and everything works: YouTube, My own banking apps (they give me a warning tough that I am rooted, but working without issues), all camera functionality, video streaming (no Netflix here to check tough), IRDA, BT etc.
The banking checks for root (if you have SU access and not if the bootloader is unlocked), this can be hidden with the RootCloak app, but depends on the banking app itself. As I said, mine warns me that I am rooted, but everything works.
As for which is the easiest method, I prefer flashing SuperSU package with TWRP recovery, since the bootloader is unlocked. It's safe and failproof.
The other methods you listed are mainly for devices, which can't have their bootloaders unlocked.
Thanks. I know the Xperia devices broke drm keys so that the bravia engine etc didn't work. But at least with them you could backup drm keys and relock the boot loader. I read somewhere that the g4 breaks the keys but it was only really streaming type service's that may be effected.
Yea Barclays just straight up won't work and there rootcloak doesn't have an exploit to hide root from that as far as I could find.
I read somewhere on this earlier too that there is an unofficial unoficial bootloader unlock being worked on sounds like not far off. May just wait and see if that way comes to light soon and if it's a safer way and revertible for warranty purposes etc as it can't be done after accepting an update looks like.

Looking for an actual root-method for amami 5.1.1 Lollipop

Hey guys!
First I have to explain that I'm German and englisch is not my native language.
Second thing is, I'm a complete newbie to the whole smartphone/android stuff.
My Z1c was almost unused since I bought it. I'll need it for now and want to root it and have an actual, stable and secure system/ROM on it. Therefore I'm looking for an "easy" method to root and unlock the bootloader. (I never rooted a phone so far)
Tried KingoRoot and Towelroot but doesn't worked. Google only showed "old" methods, so I rather ask here before bricking.
If it's possible I would prefer an other method for unlocking the bootloader than the official/ legit via Sony HP...
Have a way more questions after rooting and unlocking. Be warned! :laugh:

Not sure why you don't want to use Sony unlocking method, and also can't imagine who besides Sony would have the unlock code. Once you have the code, you could use Flashtool to unlock, but you have to go through Sony to get the code.
If you do unlock bl, rooting is easy, via fastboot/adb. If bl is locked, Kingroot works, (not sure which version you tried, but latest version is proven to work - I've done it myself at least 3 times). Most people prefer not to use Kingroot as a permanent root manager, but once you're rooted, it's easy to switch to whatever you want.
Many stable and very good rooms to choose from.
Once you got yourself TWRP 3 running you have a lot of options to choose from.
I've been modding my Z1C for two years now and i'm positive that for normal usage AOSP roms don't make the cut, there have been multiple occasions with AOSP / CM roms where i had bugs with latest YouTube app versions, random shutdowns and over-average battery consumption in idle despite kernel tweaking which are all not present in stock-based roms. I was using a slightly modded 14.6.A.236 for most of 2015 until now which worked fine but i cluttered the phone too much so it became super slow and almost unusable. I've very recently backed up everything and clean-flashed DStrikerZ1 rom because it's the most-followed rom for the Z1C and i have to say i'm positively surprised by it's UX performance and overall style. Once i know how to fix my mobile network* i'll probably recommend it but until then you might just wanna flash stock .236, root and then de-bloat using TitaniumBackup (or whatever you prefer) which i know will definitely be bullet-proof.
By the way i'm also from Germany so feel free to hit me up for questions, i'll help where i can.
*Edit: Mobile network working, just had to mess with the internet service provider settings a bit. That makes DStrikerZ the best rom i've used so far on this phone.
Much appreciate guys!
I've got the unlock code and will do it tomorrow.
Read all over about absolutely making an TA-Backup BEFORE unlocking the bootloader cuz of loosing the Bravia Engine, DRM-Keys and Track-ID so I was uncertain....
