considering buying an evo

Hi all,
Considering picking up an EVO to replace my touch pro2. If not evo, then an epic.
I was just wondering if there's a good intro link i should read up on, especially as far as installing custom rom's etc goes. I believe i need to get root access on the phone to do that, correct? is there a beginners guide on how to do that? Or a guide on available custom ROM's?
thanks

just peruse the development forums for the Evo- each link is either a custom rom available, or a root method. Read through the root methods on how to go about rooting and nand unlocking the evo.

Check the wiki first - it will point you to all of the roms, radios, tutorials, etc.
The best place to get all of that info is the wiki, the stickies, and this thread, which benchmarks over 40 kernels and will help you choose the ones you want to try. If you don't quite understand all of the data in that thread (and the website it point you to), it will make more sense once you go through the wiki and stickies.
some quick answers - you do need to be rooted to flash a rom, which may or may not come with a custom kernel that breaks the fps cap, and may or may not be over/underclocked. If you don't like the kernel the rom comes with, try another, until you find a combo that works best with your phone (because not all evo's are created equal).
Most important thing to know is nand backup (with either amon ra, or clockwork/rom manager) before flashing ANYTHING.

nand backup? does that backup the original rom of the phone in case i muck something up and need to restore it? or should i just go RTFM before i ask more questions?

lol, yeah, do your reading so you understand everything before you actually do anything. One of the subpages has a sticky on common misconceptions. It's pretty good, and someone posted a set of questions in that thread that you should be comfortable answering before you attempt root.
As far as nand goes, it backs up the current state (like a restore point in windows) of the phone at that time - so do one right before you flash anything, weather its a new Rom, kernel, radio, etc. That way if you run into bootloops or something, you can always go back to a working version of your Rom.

Not true. It doesn't back up your original rom, just whichever one you have on it when you back it up.
IE you can't do a nand backup of a completely stock unrooted rom. You have to root in order to install the custom recovery which will allow you to back up
There are a few posts that explain how to unroot. The easiest way I have found is to run the first part of SimpleRoot then run the RUU program that you can find in various places in the forum.
Also a good habit to get into is wiping before you flash. It's a pain for having to backup settings, but I've had to unroot and reroot a few times because my 4g would get borked and stuff like that.

ok - one last question, i promise (maybe). Does the method of rooting change significantly from phone to phone? i.e. if i get an epic instead of an evo, will that make much of a difference? My guess would be no since they are running the same OS. I'm still not sure if i want an evo or epic. Gonna try and take a look at them both when i head out for lunch.

The OP is new; not new to planet Earth. Obviously it's going to back up whatever you have on it.

they can vary. like for the evo all you have to do is click a button now and your are rooted. go to the epic forums to see how they work. there are a lot of complaints w/ the epic for data uploads and gps. but then again the evo had problems when it first came out too. (now it's awesome )

the OP said will it back up your original rom. No it does not. It backs up the custom rom that you put on in order to root.
The OP may not have known that, and I really don't appreciate your snide remark when all I'm trying to do is help someone out.

LoL. Thanks. And yeah - i meant it would back up whatever is currently on the phone when you run it. Obviously if i need to root the phone before using that particular backup utility, it wont be backing up the original rom.

I appreciate both your comments. I wasn't aware that that backup utility required the phone to be rooted first before using it. So I assumed i could install it unrooted, and use it to backup the phone. I do realize though that it's not going to be able to backup something that''s already changed before i install the backup program.

Ok, then let me put it another way:
In order to create a nand back up, your phone is already rooted with nand unlocked one way or another. In which case, the "original" rom is not even on the phone. If the original rom was on the phone, you wouldn't be able to back it up anyway, so by definition, what I said is correct.
I assumed the OP meant whatever rom he was on before he started experimenting with roms. I wasn't trying to be snide; my apologies if I came across that way. Maybe next time I'll put a smiley face next to my comments so they aren't taken out of context.

Apparently, both FattySparks and I were wrong. lol Yes, your phone needs to already be fully rooted to back up a rom, because it requires reading/writing from/to the system. However, once you root the phone and unlock nand, the back up you create will not be the original rom anymore. The original rom is available (called an RUU) if you search the Evo development section.

ok got it - thanks for the info/explanations

Best phone I have ever had, by far...love it.

Just got the phone yesterday and so far I like it. I really don't like the on screen keyboard though . but the speech to text kind of makes up for that

[Q] Purpose of each step.... Kinda confusing

Just got the Evo. I want to Root it. However, I am trying to understand what each step does.. for example.
All I really have is contacts and few photos that I really don't care about.
At what point in the process do I back up my current image or "Rom" so in case I FuBar I can got back to an Out the box state?
What does Rooting do? Is this like unlocking the phone?
**I know, baby steps but I'll get it*****

Your contacts automatically sync with your gmail account and the photos are stored on the memory card, so those should be safe. The ROM you can restore at anytime but you will want to make a nandroid for your 4G keys as soon as is possible.
Once rooted your phone will be fully unlocked for you to do anything you want with.

Jon, I replied to your PM.
What is a Nandroid? and how do I make that?

Okay, not really easy for the noob to learn at first, but get this.
Nandroid is well, u can find the definition on google, and to nandroid backup your 4g keys and such is part of your Amon RA Recovery 1.80 when you root your phone, you're able to make backups of your nandroid and restore them to a backup time where 4g has broken after the time being or whatever keeps the phone from operational mode to your liking.
Hope that helps.

And rooting is not like unlocking. It lets you make changes or totally alter your phone's system, as well as let you have superuser (or developer) permissions. Reeeeealy worth it. I would flash myns rom right away.

Clockwork Recovery

I have a question on restoring a stock rom with clockwork...
Im going to do a backup of my current stock rom (in case i want to go back from CM7 to what i have now, which is stock...havent even rooted yet)
My problem is that, while searching the forum, i came across this post, which scared me a bit: http://forum.xda-developers.com/showthread.php?t=838484
So, my question is, if i do a backup of my current situation, and then when i go back i just restore the said backup, do i have any chances of having the problem mentioned in the thread i posted above??
Thanks all in advance!

What you're talking about is making and/or restoring a nandroid backup of your current system, what that thread is talking about is something entirely different. There's no problem restoring your stock nandroid, I've had to in the past when I've needed to pull some apps out of it.

one more question though, just to have things clear... if i were to go back to the way i am now, and unroot and everything... i would have no problem in restoring the backup and then just unrooting?? simple as that?
thanks!

It would be slightly different. Firstly I can't imagine you needing to go back to stock unless for warranty cause there are stock rooted Roms available, but there are also instructions for unrooting around here somewhere

hey, first things first, thanks for the answer
secondly, i do understand the procedure to be different, what i meant was, if i restore my own nandroid stock backup (the one i created myslef), once restored, i'll still be rooted, right? (with s-off and stuff)
thanks

Well considering you could only actually make the Nandroid backup with a rooted rom, yes it still will be when restored it took me awhile to get used to this too, when you do a restore, save for your SD, your phone will LITERALLY be EXACTLY the same as when you did the backup (also save for any corruption that could occur, but if it's an important backup then put it on your computer )

Sorry, i just have another question (total noob here, hehehe), is root the same as getting s-off? or are they completely different things?
Cause, if i just root (keeping s-on (if its even possible)) and do a nandroid backup, and then i do the s-off... when i restore, id have root, but s-on, right?? and wouldnt that be just the same problem as the one stated in the thread i posted in the first post??
sorry again, i know im probably making a big mess out of something relatively simple...
thanks in advance

No no, it's natural to be worried the problem that what you posted talks about its trying to install the official OTA rom while s-off which you won't be doing anyways and while s-off isn't the same as rooting I believe you need s-off to root.. I'll do a bit of research in the morning but in the mean time take a look an see what you can learn on your own

Great, thanks!!! if u find out anything else, please dont doubt in sharing!! everything is welcome!!

IMEI and Internal storage problem

I did the stupid mistake of flashing to a custom rom without backing up. Nowhere in custom rom instructions says to backup your /efs folder.
Now in "About device" Baseband version is "Unknown" IMEI is "Unknown". I've searched everywhere for a fix and nothing. I tried the following:
Flash stock rom
Format /data and /cache
On keypad, dial *#7284# ....But i dont get the "Qualcomm USB settings" option so i cant try IMEI repair tools
I tried flashing different kernels and different custom roms
Apart from the IMEI problem, the Device cant access the 16GB internal memory. The stock rom flashes with no error, but when i go to
settings > storage: under "Device memory" its full with only 182MB used by some apps. I thought the memory could be bad, but after flashing
Perseus kernel and swapping external sd card for internal memory I can use the 16GB as external memory. I cant find a fix for that either.
INTERNAL MEMORY UPDATE: it seems that internal memory is mounting read only. Still trying to find a fix
Im currently on "T889UVALK8_T889TMBALK8_TMB" rom with Perseus kernel and using "11extsd2internalsd_gs3_fat32" to swap internal to external memory.
Side note: I bought the phone from a friend 2 days ago. Its the Tmobile version and I used cellunlocker to unlock to use it with AT&T. That worked, until I started messing with ROMS. No warranty available. I am desperately looking on how to fix this since i have no spare phone. Any help is highly appreciated and thank you for your time

Unfortunately sir their just isnt much that can be done for you. If you read about imei loss without a backup its just about incurable. Sorry.
And the remedy for imei restoration without a backup is hit and miss at best as to whether or not it actually will restore your number. Your best bet is to use the search function and try and experiment with different ways of fixing it. Its not like there is much more damage that can be done anyways. You already screwed the pooch and basically have a functional brick.
No one is going to post a step by step guide for you though if thats what youre waiting on. This is a complicated fix and most members wont devote the time to walking you through it
And to the member that said he searched and found no Information. Well thats just not true. Ive read tons of threads and posts about it and know about SEVERAL backup and restore methods.

Thank you for confirming my fear, I was on denial. Im getting a new one on friday. How much do you think I can sell this one for, obviously as a tablet?

Developers need to take more responsibility around here with their threads. A simple "I'm not at fault" is sub par in my opinion. Users popping up with IMEI issues are becoming more a common thing. Didn't somebody make an app to back up your efs partition? Why is there not a link to said app in every ROM and kernel thread? This stuff blows my mind.
As there is a rampant influx of "noobs" watching YouTube videos about rooting their devices (most of which for the first time) with links to ROM threads, their needs to be an influx of responsibility taken by those who cook ROMs and feed them to the general public. The issues with the IMEIs being lost is not a small one. Your device is pretty much done for without a backup. Keep reading, keep trying, but since you had no idea that losing the ability to use your device's radios was even a possibility, not your fault.
Good luck. And sorry. You should have seen a link at the very top of the thread you downloaded your ROM from ... and this whole thing would have been avoided.

Never done it. If you have a new one, just make a backup of the new one and don't mess with it. Now you know to make a backup

I would like to prevent myself from making this mistake in the future. Are you talking about the same type of back up you would do in TWRP or CWM? Like a nandroid? I've never heard about the backup your talking about, but I have been seeing a lot of people talking about losing their IMEI number and it sounds like really bad news.

After what happened to me I haven't messed with other roms. Andromizer can be found here http://forum.xda-developers.com/showthread.php?t=2080009 to make a backup of your /efs. I have also used Nandroid, which you can just download from the "play store". Nandroid apparently does make a backup of everything including /efs and bootloader. As to how to restore from those backups I would like to never find out if it actually works. I have flashed the perseus kernel with clockworkmod recovery and also rooted which allows me to overclock to 1800MHz and im very happy with it. I dont have the urge to flash any roms that "promise" any speed improvements. I have also got rid of the bloatware with titanium backup pro. And of course i made backup with it too just in case i removed something i did not suppose to. All backups are in my external SD card and on dropbox. Call me paranoid but after what ive gone through i call it being safe.

[Q] Anything I should do/know before rooting/clockworkmod/custom ROMs?

So I just got a S4 from T-mobile yesterday, and am planning on putting some roms onto it some time down the road. I'm familiar with the actual installation process, but am just wondering if there's anything I should do before, on the stock rom. I'm aware that (correct me if I'm wrong) you could always return to it later with odin, but I'd like to take care of it first. Things like backing up your efs folder in case your imei changes (happened on my old AT&T captivate), unlocking, etc.
Thanks for your help.

The only way your imei number would change is you get a new phone or a new motherboard. My suggestions is read, read and read before doing anything.

Root it. Turn off everything you dont use (gestures, etc. ) and use titanium backup to freeze unused apps. Or use google to backup contacts before flashing.

My Captivate's imei changed solely from flashing custom roms though...

Food for thought. You can also use samsung keis to restore the stock firmware also tried and true. Just in case odin fail its always good to have two restore method's

I don't know how that's possible. For the imei to change from flashing roms. The imei changes when you get a new phones or a new motherboard when you get a replacement or a repair

One of the few things that can only be done on the stock ROM is SIM unlock. So, that probably wouldn't be a bad idea to do before you go swapping ROMs whether you'd need it or not. It's definitely not required and I think can be done on the custom TouchWiz ROMs as well; just a thought.
