[Q] how to change the firmware? - LG Optimus 4X HD

hi, im new here, but i have a lot of experience flashing in my xperia x10. I've been reading about downgrading, upgrading firmwares between 10a to 10h, how to do it? is better to have one than another? i am not able to root my phone in my current firmware (10a), could i if upgrade to another one? thanks

How about searching and reading first, rather than expecting people to spoon-feed you the answers like a kid at school?

Go search, go read, go learn. Dont make noob topics.

Once that you know that firmware is changed by flashing, you already know some "key words" or "tags" to search a little

Chance of bricking..?

Hi people,
I'm new to this forum and this is my first thread..
Here is my situation, i just recently bought a Captivate through ebay and its locked.. I will try to find the unlock code using the method in this forum.. after i unlock it, i think i would love to update the android os to 2.2..
will any of this process have the slightly chance of bricking my Captivate?
i will not try to root my Captivate yet coz of the possibility of bricking it..
I will wait until there are solutions to this bricking thing, or when i feel bored i might try this.. ^_^
also, if you guys are kind enough, i would love to know what all kind of things that will brick a Captivate..
Thanks..
I am no expert but XDA helped me with my first smartphone (Palm Treo 750 bought on ebay) and I did everything without any problem. You need to read much until you understand everything clearly and always follow the instructions step by step because these guys know their stuff. Currently buy a Captivate. I love this phone. Already rooted and Im to upgrade FroYo without fear because if it becomes a brick I know that here finds it solution. Good luck.
got to read
Yep, that's the key. Read, read, read, and then you will have to read some more! I'm new to the board also, and this is my first smartphone. I've spent the past month reading threads in the development section when I have the chance (which is not very often...) and there is still a LOT of reading and learning I need to do!
Don't forget to use the search, which might or might not help. Honestly the biggest help is to read all the posts in all the threads - which will take a while!!
Lot's of great help on this board. I'm pretty close to feeling up to speed enough to cook this thing without fear of bricking...
I would wait a while before you do anything like installing the JI6 Froyo ROM. From what I've read, you have more chance of bricking your Cappy during that process than by doing anything else.
BTW, by just rooting or unlocking your unit you have very little chance of bricking your phone. It's what you can do after you root your phone that can cause it to brick. lol
Like the above poster said; "READ, READ, READ" and then when you decide you want to do something, read some more. I've been reading these forums since before August 15 when I got my captivate, and I STILL haven't done anything like rooting because I'm staying "stock" until the official froyo update is released.
Thanks for the nice reply guys.. and yes, i will keep on reading through this forum..
btw, from what i understand, rooting will enable your phone to install android apps from worldwide market right? does it safe? i mean, i heard that someone bricked their phone while installing some apps..
If you are interested in side-loading apps, try the Android Sideload Wonder Machine (it's called something like that). It works well for me. I'm not sure if this is exactly what you are looking for, but it is useful to know.

once you are rooted, you would still have to enable market access (for apps outside your att restricted market)
i would like to see how installing an app bricked a phone.....i call shens.
rooting is easy, and just by rooting your phone you wont brick it. you would actually have to do something to harm it. even then, its all recoverable via ODIN.
Sorry for a noob question.. but, what is JI6? ^_^
JI6 is the version of froyo (android 2.2). Go on the phone to settings-> about phone-> it's in the baseband version. Mine is I897UCJI6 (froyo).

[Q] Reinstating warranty questions!

Hello!
Let me just say I have been long overdue with registering here. I have been looking for help threads here for about 6 months on my Galaxy S3 phone and other questions. Awesome forum and really loving it.
And also, if this question is somehow "overdone" (I can see it being a question at a regular basis) OR posted in the wrong forum. Then sorry! I am however very thankful for a reply to it, and if this thread needs to be moved then go ahead. (And if it needs to be taken down, I would be very thankful for a reply)
I installed a custom rom on my Samsung Galaxy S3 i9305N a while back. First I used clockworkmod to fix a loader, rooted and all that stuff. Then I installed the only Cyanogenmod I could find. (It wasn't an officially supported one at the time, I have no idea how that rom is doing now however)
I then reformatted everything to the original loader and rom. It looks mostly the same as it did before, but with some new features.
However, I need to send the phone to repair. The battery is defect and the charger seems to drain its battery.
A phone support guy that I know, told me that it is possible to see a "history" on all the roms and roots and etc, that has been done to the phone. In order to make sure that nobody reloads the warranty Rom and sends it off to repair. Is this true?
If so, how can I fix this? Is there any way to just reboot the phones so called history? Or did he just tell me this to scare me off?
Is there any way I can test my Samsung if it is eligable for warranty, without sending it off to their repair? (And do they check all phones for custom roms?)
Thanks for any help! Sorry for the LONG thread.
I am not that good with computers and programming. Could be worth mentionning! I managed to load the rom through tutorials, that's it. =P

Thanks for the reply, but where in the general forum can I find this guide?
Edit: also How do I hide any possible traces of having had a custom rom? Thanks for any help.. Or URLs with help!
Fine
Hi..don't worry asking as long as you have stock ROM and zero flash counter and stock kernel..I did the same sent phone off and received phone back within week..good luck...

Thank you very very much!
In fact, thanks to all good replies. The triangle thing was what I was looking for! I am a total rookie but I feel as though I learned quite a lot. Perhaps I should root my new phone now. "Haha".
No but, I actually got one question.
How do I know if it really is my official rom? I read somewhere, that every telephone-operator has their own Rom. So just picking one of the Roms might not work?
How do I know if the source is correct? I'm a bit concerned that I might format the phone, send it in, and they notice that I flashed with the wrong Stock Rom.
I have a Galaxy S3 i9305N with the operator Tele2 in Sweden. Sammobile.com has 3 stock Roms available (One only for members though) Which one is correct? Or does it not matter?
Thanks for any help again.
Many apologies if I am a bad googler. This is one of my first issues I have never been able to Google my way out of ;P
EDIT:
GT-I9305N Sweden 2013 March I9305NXXBMC2 I9305NCOVBMC2
GT-I9305N Nordic countries 2013 January 4.1.2 I9305NXXBMA2 I9305NNEEBMA2
GT-I9305N Sweden 2012 September 4.1.1 I9305NXXALIA I9305NCOVALI7
Those three are my result. How do I know which one I should go with?
EDIT2:
I was looking around a bit. I think the right one would be 2013 March (Top) right? Thing is, I find another one through a Swedish forum with a thread just like this one.. and it puzzles me what to pick. Does it matter at all? I used the one from the Swedish thread a while back, and I noticed it differed a bit from the Rom I had on the phone from purchase... Is it best to go with one from Sammobile? (And if so, which one.. )
Okay my friend! I checked it out...
On http://samsung-updates.com/device/?id=GT-I9305N are only 3 firmwares for the I9305N
BMC2 is for Sweden and 4.2.1
BMA2 is for Finland and also 4.2.1 but
ALIA is for Sweden an 4.1.1!
Now is the question with which firmware your phone was coming?
I guess, my friend, I don't know the answer... you could try each firmware...
I'm sorry, I really don't know!

From what provider did you buy the phone (after you know that search the internet for the firmwares it provides to your phone).You only need to search a bit then you will find the rom you need. Gl.

[Q] Razr I Noob

Hey guys I have been looking into rooting my Razr I.
I think I have the basics sorted but I wanted to check a few things.
I have been reading this guide as I have 4.1.2 currently.
http://forum.xda-developers.com/showthread.php?t=2123369
So I unlock my bootloader then do I need to flash CWM? Also what version is best?
Also been looking at Roms. Moto JB looks good but I cant really find much else. any suggestions?
Sorry for all the questions but I dont want to brick my phone :good:

[Q] Camera with bootloader?

Sony has said that installing bootloader in the Xperia Z1 will disable the camera, but I've read that if you recover the TA, the camera works again. Is this true? If so, could I install different kernel ROMs (like CM) with a working camera?
I'm sorry if the question sounds dumb, I'm new to Android.

Firstly, you don't "install" the bootloader, every phone has one, you just unlock it to get access to it.
Secondly, you can restore the TA but that RELOCKS the bootloader so you cant use custom kernels.
Trust me, when this issue is sorted it will be big news so you will get to know it.
Currently this is the situation
locked bootloader = stock kernels = working camera
Unlocked bootloader = stock or custom kernels = NO CAMERA
No question is dumb if you don't know the answer, but please get used to searching before asking, that way you definitely wont ask any dumb questions
Thanks!
But the only ROM with the stock kernel is HONAM1Z, and I have no idea what features it has....
The other stock kernel ROMs are just updated firmware with root, but there are 2 that are basically the same. Which one should I use?
Do you need bootloader for mods? (like PureXAudio)
You choose any one you want. No one on here will tell you want you want, its up to you to try, test and decide for yourself.
As for other mods, no you don't need bootloader unlocked. That is only for custom kernels.
If you read the OP of each mod it will tell you the requirements and if it does not say "Requires an unlocked bootloader" then its fine to use on a stock kernel.
You will just have to root, install recovery and flash them.
Do ROMs need to be of the exact model number?
For example, you have a ROM for the C6903, but I have the C6906. Can I use the ROM?
Or if mine is build number 14.1.G.1.518, and yours is 14.1.G.2.257, can I still use the ROM?
And does the phone get unrooted when updated OTA? And how do you know which build number is newer?
I would first suggest you read the tutorials in the general section and the dev section.
Most, if not all, your questions will be answered there and I will only be cutting and pasting information from there.
As something to think about, when I first joined xda I spent a LOT of time reading guides and tutorials before doing anything to my phone.
I am not saying I wont answer your questions, but the answers are out there for you already and taking things steady will give you the best chance of learning and not doing something daft to your phone and bricking it.

No need to read ALL the threads, but the opening pages contain important information. If after reading those you still have questions you can ask them in those threads and then people can help you there.
Best of luck, and I am available via PM if you need me
Thanks for the threads! They were pretty useful
Although I still have questions about ROMs. If your room is for C6903, and I have 6906, can I still use it? I would guess that you can, as the only thing that change is the baseband.
Also, what ROM do you recommend? Yours (http://forum.xda-developers.com/showthread.php?t=2504638), this one http://forum.xda-developers.com/showthread.php?t=2440408) or generic 534 (http://forum.xda-developers.com/showthread.php?t=2505796)?
Do you know what Honam1Z? (http://forum.xda-developers.com/showthread.php?t=2463675). I cant seem to find the advantages of the ROM....
Thanks again for answering my questions, mate.
And I'm sorry if you have received this same message by PM. My sent box appeared empty after I sent it, so I didnt think it reached you.

Hello. You can download the Original Stock ROM from Sammobile. Note down your Build Number which you can find Under Settings->Phone Info. Then head to sammobile and search for your Version,and download it. Beware that updating to lollipop,your baseband and Bootloader will change. You will also need the BL and Baseband for Kitkat,which you can find here on XDA,there is a collection just search for it
I know about that.
I've done it using Odin on my Samsung ACE2, but found different from original ROM!
One time I've upgraded to version 4.1.2 and it was so slow, that I had to downgrade again.
Just found Russian ROM to downgrade and it's a little different from my country.
If there is no option, so I will let the S5 go to Lollipop!
Let see if I don't get Camera problems, GSM or Wi-Fi.
I will cross fingers!!!
thank anyway
Already let my phone to update to Lollipop and.....
1st impact..... I DON'T LIKE IT!
the green-blue background colour is terrible.
why not possible to change this theme, to black for instance?
the biggest negative problem is that I can't get write access to my micro-Sd card.
read in a lot of sites that wire access will be given to 3rd parties apps, but NOT TRUE!
does someone that has Lollipop has wire access to sd card with 3rd partie app?
thanks mate

because its not their job to pander to everyones needs. theyve used the same skin and color scheme for years now and its up to you to do research into what phone you want to buy and how it looks. the update has been out for so long that you could have seen its looks before you upgraded
