I just wanted to make sure first if its safe too root and it wont affect future upgrades?
So far im liking the phone which is my first android phone and 2nd android device with my galaxy tab
And really liking the speed of it heck its faster than my galaxy tab which is overclocked at 1.4ghz and running voodoo kernel , Imagine the atrix being overclocked That's if it ever comes too that hopefully in the future.
But ya would like too root it at least for now .
If you arent comfortable flashing or not having an easy way to go back to stock, I would wait. The Stock ROM* that is listed in these forums is not easy to go back to absolute stock with, at least not for beginners. You have a possibility of messing some things up if you dont read thoroughly and know what exactly is going on. A lot of these posts in this sub forum are DEV related and shouldnt be performed by someone without a good knowledge of ADB.
Also, just a heads up, this really isn't development related. It should have been posted in the Q&A forum.
Moved to Q&A as not android development
whoops sorry i thought it was suppose too be in dev thread but thanks for moving it
So just rooting it you cant go back too stock easy if i have too? I saw superoneclick can root and unroot it but just wanted too be sure it wont effect any upgrades,
1) How comfortable are you with command line tools?
2) You may f*ck up your device (may.. not likely but still). How confident are you that you can recover it, even if it's coming on the forums and getting detailed information to help someone here help you

Just rooted and everything went fine
Well im not sure about this device but i did recover my galaxy tab that i thought was bricked from a bad kernel flash and had too flash back too the stock firmware and got it back too perfect than i flash back too the voodoo kernel and its working perfect
Usely i can probably recover any device as long its not 100% brick.
But my main question was will this effect new firmware upgrades and stuff?
On my galaxy tab it wasn't a problem upgrading too one of the sprint updates when rooted but it wouldn't update when it was on another custom kernel, So i guess it will be fine on the atrix when rooted?
Hey everyone!
I'm new to Android, and am a proud owner of a new Galaxy S II!
I love the phone, but with me being a techy type and gadgety type I've obviously heard a lot about rooting devices and so on.
I've heard a lot of perhaps dubious information about how rooting and removing the Samsung Hubs improves battery life, as well as removing the O2 branding I have on my phone. I'm interested in this but have some questions.
Firstly, are my assumptions above correct? Will I be able to improve battery life? Will rooting remove the branding?
Secondly, does rooting essentially erase the device - will I lose contacts, messages, settings and so on?
Next, does rooting void my Samsung warranty, and does it void my insurance?
I have one other question - in my Settings > About Phone menu, the kernel version is listed as:
2.6.35.7-I9100XWKDD-CL161513
root AT DELL103 #2
What is the last line there mean, the "root AT DELL103 #2" mean? Am I already rooted?
I'm sure these questions seem silly to some, and I'm sorry if these have been answered before. I'm very grateful for any advice from the more experienced Android users.
Happy to be joining you!
Congrats on the new phone! I'm jealous, I live in the US and we are still waiting for the SGSII. Anyway, I can't answer all your questions but I will answer what I know to be true. As far as battery life is concerned, once you root, you will need an app like Titanium Backup from the market to "Freeze" the media hub and other bloatware you don't want. Doing this will stop those programs from running all the time, which will definatly help conserve some juice. Rooting will void warranty, but if you run into any issues which will require you to warranty your phone, you can very easily put it back to stock with Odin. Odin is a tool that allows you to flash factory files and return you back to stock. Rooting will not erase you phone, it will just install an app called "Superuser" which will give you the extra privileges needed to run Titanium Backup and to do other fun stuff. And lastly, your phone is not rooted already, this is just what the Kernel is named. As far as the O2 branding removal, someone else will have to answer that for you, considering we don't have O2 here, sorry. Hopefully this helps in some way. Good luck and welcome to the community!

Rooting:
- won't improve your battery life
- won't delete any of your settings/apps/contacts/messages (or any other data)
- It will void your warranty (you can always reflash the stock firmware to get it back)
- Your Insurance is likely still valid (check with your insurance provider for conformation)
- Your aren't already rooted, mine said that as well, I don't know what it means
- Rooting won't debrand your phone, to do that you'll need to flash a generic firmware (available from one of the SGS2 dev threads on XDA)
I hope that helps you

It does help, on the battery life bit though, surely removing / freezing Samsung crap will improve it a bit? Or is the impact negligible?
If not, then is there much other point to rooting?

I've made a load of YouTube videos on a) how to root and b) the +/- of rooting. Just search "mattj101101" in YouTube. They explain it far better than I can here. As for battery life, I've noticed no difference after rooting + or -
I recommend subscribing to him also.
Looks like I'm not the only one with the same questions. I do have another question though: after you root the device, can you still use KIES to upgrade to newer firmware or do you have to flash?

I'm not sure if this is a blanket answer, but my Kies now says it can't update but since Kies nearly bricked my phone updating to XWKE1, I'm not to bothered, it's a s**t piece of software, Odin is much faster/more stable. I recommend using it.
Thanks guys - I think I'm gonna hold off on rooting until the process for SGSII is more established. Don't want to risk wrecking it just yet! In the meantime I've just taken to ending the Social Hub service.
On a side note, has anyone had a problem playing DRM-free files but the device complaining that "the device is not authorised to play this divx-vod content"? I have completed the VOD registration process but no luck. This is video that was taken on a compact camera, and plays fine on anything else.
Thanks again.

I know what you mean, I had an HTC Desire and using Unrevoked to root and CWM to flash new rooms/updates is totally different to flashing via Odin.
First of I'd like to say hi as first post here. By the way love the video lmfao.
Ok so I have just brought a galaxy s2 after years of iPhone. I have been jailbreaking iPhone for about 2 years and have no prob in this. I have been doing dome reading on rooting and I have no probs with doing it would just like a few Q answered first if you would be so kind.
1: does the carrier matter when rooting?
2: does it depend on what version u r running(like on iPhone)
3: what is a kernel and y does it need to be made inseurce?
4: can I brick my phone?
5: anything you think I need to know or articles relating to my Q above.
Many thanks

1: When rooting, the majority of the time it'll be with a stock rom rather than a branded one. For carrier specific kernels you can do a search, I don't know about carrier specific software.
2: Yes and no depending on how you root. If you install a ROM that has been developed in the original Android development thread then on the majority everything is included. If you're simply going to apply root by overwriting the kernel then you need to ensure you download the right kernel. For example, O2 are still on the KE2. Previously I was running Darkys which I believe had me all the way up on KF7, but I wanted to go back to stock but also retain root. Basically search the forum and you'll find questions just like this.
3: The kernel is the operating system. It needs to be made unsecure to allow the core applications that allow and manage root access. A secured kernel is one that doesn't have root access and therefore reduces your abilities as a user by 50%.
4: Not easily done with this type of phone. Just don't use a dodgy cable. Ensure everything is plugged in and powered properly. Check and double check that you've got the right source files if you're only applying root to your stock rom. FOLLOW INSTRUCTIONS - you will see over and over that you don't apply a ".pit" file modification using the SGS2 firmware update software ODIN. Read threads to learn more about this.
5: Check the thread you're interested in. Only questions relevant to that ROM, Kernel or other elements can be answered in that thread in particular.

hi Benjio21
yes the carries matters.
The proprietary files are changed so there can be a problem you can loose your gsm.
Yes i does matter what version you are running but a bit only.
Actually there are roms which don't have a rooting facility. And some else kind of glitches but there are always eventually a work around.
Kernel is that program written to make the software interact with the hardware the commands generated by the program eg overclock are conveyed to the hardware by the kernel only.
Regarding the insecurity I'm unable to understand your point.
yes you can always brick your phone.
So to be true always play safe try to get more info about anything you do.
But when you do thing s properly and as they are being told to do there are seldom any problems most of which can be sorted out so no problem.
I will provide you few articles pm me the topic.
And one more thing you can always get more and more info by going to other devices forums.
Happy androiding...!!!!!

Looks to me like that's a downgrade.
Your questions should be asked in the particular thread though.
I've had a HD2 running Android for a long time now so i've got to understand the lingo. As for the SGS2 stuff, i'm still having to learn myself so i'm quite hesitant to just do things on a whim.
My preference has been to download the stock O2 ROM to put it back to factory settings, then install an insecure kernel to obtain root, then overwrite the kernel with the original from the O2 ROM i'd just installed. What this achieved was simply no more yellow triangle at boot, a stock ROM look and feel, but full user facilities.
I believe that method has been referred to as the 'noob' method of rooting, but since I didn't see any performance enhancements from using a custom ROM I didn't see the point of keeping it.
All,
Originally posted a request for help in the Galaxy S4 International forum for using Odin to downgrade my Verizon Galaxy S4 SCH-I545 from Lollipop to KitKat.
http://forum.xda-developers.com/galaxy-s4/help/odin-fails-to-downgrade-galaxy-s4-t3278803
Eventually one helpful guy mentioned that Verizon crippled this device with a locked bootloader, (or a mismatched age/version of the bootloader) something never even hinted at in ANY instructions I've ever found for using Odin. I'm really disappointed in the Lollipop version that I've been stuck with, mainly due to the slowdowns on the phone and the need to kill off all apps at least every day., and the need to hit buttons multiple times before enough system resources clear up and it does what I want. All I wanted to do was go to an earlier version, and it looks like that might not be possible.
I see forum posts talking about rooting this version of the phone, but I don't have a handle on what good that will do for me in my particular situation. Now that I've found the correct forum, any suggestions? Part of me likes the idea of rooting and debloating to speed things up, but if I can't downgrade and the performance reduction is just a function of the version of Android I'm stuck with, then I don't see the point in wasting even more days of my life fighting this aging phone.
Oh, and as an aside, what the hell is OC1 and OF1? Can't find anywhere that explains what the heck they're talking about. My best guess is they're versions of firmware, are the designations just random?
Thanks!
Ryan
I'll try to write you some things i've learned about this device, hope it helps you
Samsung Galaxy S4 Verizon SCH-I545 has the same specs than others Qualcomm Galaxy S4, but this one is managed by Verizon to distribute, update software, etc... That means, even when it has the same hardware than others it will have some differences on software and limitations. Now, let's talk about our "charming" bootloader:
When we talk about bootloader, we use as reference the last 3 characters of bootloader version (this also applies to firmware, kernel), you can get your bootloader version by running this command on terminal emulator getprop ro.bootloader (this is why we refer to lollipop OC1, OF1, to kitkat NG5, NG6, NK1 and so on) when you get a software update almost always your bootloader is updated. Only MDK bootloader (first firmware released) was unlocked. After that, Verizon decided to start locking the bootloader to prevent rooting, software downgrade... So, why don't we unlock the bootloader? because they used something called qfuse, the qfuse is hardware related and when it's triggered (updated) cannot be untriggered (downgraded).
After reading this you may be really dissapointed and thinking to get another device, I was in that situation, but you can root your device (this means, you can debloat and do something to speed your s4), even you can install a custom rom's (they're really nice), maybe it's not the best solution, but, hey! it's really better than stay stuck with device stock rom. Btw, you cannot downgrade with custom roms, you can just install those that are meant for your bootloader or higher.

That is what I'm leaning towards. The frustrating part is the time wasted trying this in the first place. I think I'm just going to cut my losses, suffer my crippled phone with quiet grace and dignity, and replace it at some point.
Thanks for all the help!

So, is there any way to root a Galaxy S4 verizon phone with 5.0.1 (Lollipop)?? I've been reading threads and how-tos and trying various techniques for several hours with zero success.
Don't despair too much. There is a great dev who has provided the means to flash a very stripped down version of Lollipop OC1. I can honestly say that, in the 2-1/2 years I've owned this device, it has never run better since installing his ROM.
It is still a Touchwiz ROM, but everything, and I do mean everything that can be considered crapware has been removed from this ROM. The result? a slim, sleek user experience that will cause you to never look back (considering we will NEVER have a true AOSP ROM for our device.
Check his link out below. Read everything and make sure you understand what you have now and what you will need to do. Then study some more. It took me a month before finally feeling confident to make the plunge. Even then I needed help, but got all I needed from the good folks...especially Stang5litre, on the discussion board.
Good luck!

Hi,
so I am having issues with the Wifi on my, recently acquired, LG V30.
I have got a strange model, L-01K, from Japanese provider DOCOMO.
I have unrooted / flashed .. currently running Havoc 3.11 on Android 10.
The wifi often loses connection/signal and in order to restore requires a complete device reboot.
Looking for some help.
Regards,
H.

Is this a joke ?
Not really a joke... did the phone work fine on a stock ROM? You never told us what you came from.
How did you get to Havoc 10? As far as I've seen, Pie ROMs often have issues after install... I can't imagine 10-roms to be any better. Did you try any of the fixes mentioned in the ROM threads instead of just asking here? Sounds like it's probably ROM specific...
Well, is it my first custom, so I have no past experience and I don't know if this is specific to the ROM or the firmware drivers, or etc... hence I am asking around here for some support.
I assumed it was clear where I cam from, I came from stock. I only had the phone stock for a short period so I do not know if it was better or not before flashing. The phone was trully horrible with all the Japanese software crap on it.
I think I saw somewhere that this phone is known to have crappy drivers from LG.

You also don't have a model number I've ever seen before, nor is it mentioned in the WTF thread. We have no clue what you installed here or how you did it, so I would suggest flashing one of the stock ROMs through TWRP if that's your bag. The Havoc ROM used in this forum is v3.9, again don't know how you got 3.11
Perhaps its not 3.11 ... I got it from the V30 Telegram group ... the zip file is "Havoc-OS-v3.11-20201128-joan-Unofficial.zip", I cannot seem to find the running software version, so I dont know how to check ... I am also trying to get some help there but I thought it wouldn't hurt to ask here as well.
are you rooted and or unlocked bootloader?
Also I've never heard of there being an issue with WIFI on this device.
Yes. TWRP installed as well
You say you came from stock, but WHAT stock? Oreo? Pie? US998? Something else? All this matters. You can't just slap a ROM on without having the rest of the stuff prepared on this phone.
As others mentioned, the model number doesn't make sense to us, so it could be some weird stock ROM that is not compatible with Havoc (or other custom ROMs). Even for many of these, you need to start with a known stock ROM, so that the proper blobs (binaries) are present as well as the partition layout in the phone. As you don't seem to know what it was (eg US998 is preferred) then I'd recommend you start there and then move forward. This means Frankensteining to US998, then moving forward.
Of course, given your weird model number, this may not be advised either... but if you want to try that's where I'd start.
OK.
So, phone came with stock Docomo android 8. Dont know too many details as I didnt kept it long.
Then I had some discussions on telegram group, where people advised me to unroot the phone, and install TWRP. It was mostly same as described in the thread for the LGv30 here in the forums.
I had to install a pre 2018 ROM version, using samsungs tools.
I don't recall anymore all the details order i did things from this on, I followed the steps as advised ... but I had to flash a V300 to H930 ROM. I also remember that an important step in the flashing process was not to flash modem, xbl and xbl2. So I did skip those.
Then initially I rooted Revolution Remix android 9.0, from stock android 10.0 ... by mistake, then I reverted back and I installed Havox android 10.0 instead.
The stock filename was "H93020d_00_OPEN_EU_OP_0326.kdz" and "V300_to_H93031a_converter.zip".
Edit: perhaps it wasnt Android 8 but rather 9 as someone corrected, this phone did not shipped with android 8. As mentioned, I did not keep the phone stock for long as it was literally unsuable with all the Japanese software, so I have not paid too much attention.

You're ostensibly trying to combine 2 tutorials and forums to fix your problem. My guess is that flashing all those random ROMs, unrooting to install TWRP (?!?!), and using a Samsung tool definitely were not the right move. I'd advise against doing anything else unless @ChazzMatt gives his blessing, but he's away for a bit. Either that or ask for your Telegram friends to fix what they broke.
Also, wtf is docomo? The V30 did not come stock with Android 8.

If you had read my earlier posts, I explain who is docomo and why I have such a weird model.
They are not my 'Telegram friends' but a community of people who use the LG V30. From what I gather it seems several of them are very active in ROMs, fixes and also part of the XDA forums here. They continue trying to help me however I though it would not hurt to also ask here in parallel ... it is also far easier for someone who later may face the same issues, to benefit from the solution if they can find this thread. Perhaps it was a mistake, this reminds me why I dont really miss much using forums ...
Using the LG tool was definitely the right move as written everywhere in the forums here and advised by anyone you ask to directly. As a first step, you need to break the encryption/security on the phone and you can only do that by reverting to an older version, preJuly 2018, where a known exploit exists. And guess what, until you root the phone, you can only do that by using a tool developed by LG.
And yes, I am definitely trying to combine several tutorials as there simply is no single tutorial or source of information.There are also no instructions, or even knowledge, for my model on the forums, and since the information is vague, outdated or incomplete on the different threads, you simply have no choice other than combining it. I followed the instructions as advised by my 'Telegram friends' considering it was clear I had to Frankenstein to something anyhow and the information they gave me, It all made sense, when compared to the forums information and according to the rationalle that they gave. So I took the risk. It worked without me bricking my phone, so I consider that a success.
It was definitely not 'random ROMs', if you go into the XDA section on LGv30 it is clearly explained why you need each of those and how. Its only the specifics, and versions, for my case that is not clear.
Seriously dude, you obviously have not enough knowledge nor interest in helping, .. so why don't you do me a favor, ignore this thread and go spend your time somewhere else and let others who can actually help reply... thanks, seriously!
Oh OK, no problem. Hope you and the other user who bothered replying twice can fix your cockup. With the 0 Likes and 2 weeks on XDA, I'm sure you'll solve it immediately.
... another really helpfull post, you really never disappoint ...
You really need to be far more clear in what you are doing or did. Don't blame the other users for your mistakes, nor should you complain to them when they're trying to help you with limited info. If you want help, you need to give a LOT more info. And you did, indeed, flash multiple different custom ROMs, which is a recipe for trouble.
Your terminology is also confusing, as you keep saying "unroot" and then install TWRP. You need to unlock the bootloader to install TWRP, maybe that's what you mean. Unrooting is a very different operation. You need to be precise in what you are asking for help with, otherwise you'll get bad info from anyone. Know the terms and use them properly, otherwise we can't help you... bad info will always lead to trouble.
Bottom line, as far as I know, there's only one way to do this right on the V30, which we can only assume you have. If you want to proceed, then you need to focus on one process and not try to mix with every other person's idea of what's right. Chazz has been great on this, and has provided detailed info... follow that.
Again, I won't tell you to do this because I don't want you to blame me if you brick the phone. So, if you want to proceed, you do so at your own risk. That said, I would start by getting to US998 stock ROM via KDZ. Follow the Frankenstein thread hereon XDA to see how to get there first. Once there, check to see that the phone operates properly - it should. If it doesn't then stop jumping around and fix that first.
Once all is good on that stock ROM, follow the WTF thread to install TWRP again (KDZ will remove it), with the version mentioned there (there may be newer versions, but you need to stick to what's detailed there to prevent problems, as those are the ones that are tested and known to work). Once you get that done, again, make sure the phone is working properly... then you can consider going to a custom ROM.
If you decide to move ahead, then you need to read the requirements of the custom ROM carefully. Most PIE ROMs, for example, require the PIE blobs, so you need to get to a stock PIE ROM as prescribed before going to a custom ROM. I don't know what the specifics are for 10-ROMs, so you'll have to see what's possible and how it's done based on that ROM's thread.
Well, I am not blaming anyone for my mistakes nor am I complaining to anyone trying to help me, you've been really helpful so far, not only giving ideas on what could be done but as well trying to teach and correct me, and I haven't complained about it.
However, the other guy is literally just patronizing.
Even for me who is new to this, I can clearly see by his comments that he doesn't know what he is talking about, this device in particular, and he even didn't bother to read Chad's thread to try and understand the typical, normal, process.
Just feel free to read again everything that I posted and everything that he posted, 'helping' me, its all registered above.
As for your points you are right, I am trying my best to understand all the details, but as you can notice I have literally just registered here in the forums and this is in fact my first attempt at customizing an android phone ROM.
I have initially, wrongly assumed, that the information I provided was enough and I expected this to be a more common issue that someone with experience could quickly point me to the problem or what I did wrong. And yes, my terminology is wrong, nothing I can do about that at the moment. The posts and information are literally full of jargon, abreviations, code names and sometimes spread over multiple replies or even different threads, this is not for the faint of heart and anyone new will always struggle to understand it all, no matter how smart they are, ... I am literally doing my best to try and catch up as quickly as possible.
So, wherever you read 'unroot' earlier, just replace with "unlock bootloader". As far as I understood it, and as I recall all the things that I have done, I have literally followed the process outlined in Chad's post here in XDA ... I have however frankensteined using the V300 to H930 patch, also according to instructions outlined here (I'm not sure at this moment, if that is also a post by Chad) as per the advice I received in the Telegram group. BTW, I have looked into the telegram group and Chad is also part of it, though he has not been active in the past days, so its not just a random group of people as pointed out earlier.
Anyway .. as far as I was explained, this device requires you to first flash A9 before going straight to A10, otherwise there are some 'blobs' issues with it, i dont really understand the details. During the process of discussion in the chat group, there was some miss understanding and I ended up going straight to A10 and then I installed LineageOS. Later when we noticed this, I tried to correct this by then going back again to A9 and then A10 and then finally I installed Havoc instead of going back to LOS.
So there was some mix up there, and I mentioned this not to blame anyone but just because I thought this could potentially be a source of the problems I am facing and a hint at the potential solution.
Thank you for your suggestion, I am literally half way in the process of sort of doing what you suggest. I am now back to stock A9 and see if the WiFi behaves better. I did flashed stock via TWRP, not KDZ. So I did not went all the back as you suggest. If this proves unsuccessful I might do that.
Not that he/she/they needs my defense, but ldeveraux is a senior member (more-so than me) and has tons of knowledge on this device, in my experience. That's all I want to say about that.
So it sounds like the problem was jumping to A10 from A9. Also, using instructions from one ROM to end up jumping to another. Each ROM has its needs/requirements, so you can't really do that. Also, at least on this phone, going between Android levels is somewhat tricky, so you can't just jump around from what I've read.
Yes, there can be some jargon and such. Chazz's thread (post 193) explains most, if not all, of that, but if you're missing something I strongly recommend reading MUCH more, rather than just moving forward. It is a very long thread, but it's very important you read through ALL of it, and understand it before moving forward. Then read it again. Don't read it on a phone/device - use a computer because browsers and apps have a bad habit of truncating the message. These are Chazz's recommendations as well, for good reason (and also at the top of this thread). I did a TON of reading before I did my phone unlocking/rooting, and with that thread alone, so I have read it MANY times myself (well, at least the older revision when I did my hacking) and I didn't have to ask questions... so I know the answers can be found.
US998 is the best "foundation" to start with for various reasons. Fact is, US998 should work on pretty much any carrier to start with, so it's a great foundation for that reason too. That's why I suggest starting there to be sure you have a good, working basis.
I have read that if you go to A9 or A10, going to another version may require going all the way back to Nougat first. You may need to do that now, if you want to get back to a stable US998 to begin with. The Pie/10 threads probably have info on this... I haven't read them up myself as I don't want to bother. I have stuck with Oreo because it does everything you need anyway... I see no advantage to Pie or 10. I believe Chazz has also stayed on Oreo for this reason.
Senior or no senior, he should just not patronize people. He has clearly the option to ignore if he doesn't feel like helping .. I have even politely asked him to do so ... but instead he decided to come back and patronize further ...
I rest my case...
OK. So, I am still in the process of finalizing everything, but I think it is safe to say that for the L-01K models, the US998 is the safe way to go.
Make a backup of your modem partition, then do the Frankenstein to US998 then once you are done, you can restore you original modem partition and everything should work fine!!
