Which ROM - EVO 4G Q&A, Help & Troubleshooting

Im new to ROMS and rooting and Ive been using Baked snack 9.7 kernal #2 for a few days. One thing Ive noticed is the poor battery I get- even having setcpu setup correctly, Its a stretch to get a days worth and Its just idling with screen off.
I want a ROM thats stable, fast but able to have better battery life.
I used unrevoked3 to root and i also have nand unlocked.
Im also confused on what all I have to do in order to use a different ROM, without having to loose all my apps, contacts and information on my sdcard. baked snack 9.7 didnt have apps2sd, so how would I go about this if another ROM has this option?

ROMs are pretty much a personal preference, but I'm a gigantic fan of Fresh's ROMs. I'm waiting for root method for 2.2. I was impatient and had to upgrade NOW!!! I'm on the leaked version and can't even get the official OTA yet.
Anyway... Check out Fresh. He recently updated it to reflect Froyo.

Use Titanium Backup to backup your apps and app data. You can even back up accounts, user settings, scenes, etc. Then flash different ROMs until you find one you like. I recommend Fresh 1.0.1 plus the netarchy 3.7.3c kernel (Fresh-compatible version). Then set up SetCPU as you see fit. Reinstall Titanium and restore the apps, data, and info that you want.
To flash a ROM, just copy the zip file to the root of your SD card, boot into recovery, wipe data, cache, and dalvik, and then use the menu to flash a zip from your SD card and choose the one you copied to it. Should be pretty straightforward.

Im only confused about compatibility of Radio versions, etc. And do I have to partition my sdcard for apps2sd?

just rooted need help/advice

So i just did the 3 step root and im at the clockwork mod recovery screen
There is different stuff to choose and i have no clue what to select?
Can someone please direct me to what to do next this is my first android phone and i have no idea how to load a rom or what i should be doing next
thanks in advance
Well are you hoping to flash a custom ROM? If so, you'll need to download the ROM and copy it to the root of your SD card. Then when you boot to recovery, choose the options to wipe data, wipe cache, and then install a zip from SD. If you want to back up your phone, choose the Nandroid option.
You got pretty far without knowing how to complete your journey.
so if i click nandroid that will back up what my phone is set at now?
what is a good custom rom to use ?
I would like to have wifi tether but do not have 4g and probly wouldnt use it very often, i read something that there was a stock rooted rom? I also do not want to lose my camera?
Start here:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Evo_ROMs
Then just read up on the dev pages/threads for the popular ROMs. I use Fresh 1.0.1 with the netarchy 3.7.3c Fresh-compatible kernel (haven't switched to the new one that just came out today). Camera works great, wifi tether app is built-in. If you want that, download both (just search here), put them on your SD card, reboot to recovery, and flash the ROM, then the kernel. You don't have to flash a new kernel or even radio if you don't want to, but everything is installed the same. Usually reading a couple of pages for each ROM will tell you if there are an problems. Other options are the stock rooted ROM, DamageControl, Baked snack, or there are a couple of new ones for Froyo as well, but they have some features left out (like 4G, wifi, MMS . . . depends on the ROM).
Nandroid (or, inside Android, ROM Manager) will make a system image for you, saving everything exactly as it is. To restore, boot to recovery and choose the correct options for that. Should be pretty self-explanatory.
Always wipe data and cache before flashing, and it's a good idea to search Google for Cyanogen's recommendations for recalibrating your battery (it's on his wiki). Just don't flash a stock, non-rooted ROM or any OTA updates that Sprint tries to push on you. Always get something that the devs here say is safe for rooted phones.
Hope that clears some things up for you.

Should I update my recovery?

Should I update to the latest Amon_Ra recovery? Are there any benefits to doing so?
I have v1.8 right now.
1.8 is a good recovery. I would stick with it unless you plan on flashing CM7. The new recovery versions also backup Wimax.
If you don't care about any of that then I would stick with 1.8. Still one of the best out there in my opinion. Works like a champ for most things.
Eventually you will have to update once all the rom developers update their stuff but for now you are good.
Like the user above said, you can keep it or upgrade. If you use rom manager, you can easily flash an older version if you needed to switch roms, but it can be tedious. SO like he said, if you aren't gona be using CM7, or Evervolv, ect, you can hold off...for now.
The new amon (2.2.1) allows you to select a zip from any directory, has selective backup and restore, and also an extended wipe menu. I have been using the beta 2.3 and it is WAY faster, takes me like 90 seconds to backup boot/system/data
So even if you don't want to update to 2.2.1, i would definitely get 2.3 when it is released!
I like 2.2.1 because now i can have a folder structure for all my roms/apps/utilities

Kernels and flashing

Noob here.
I had a question about kernels. What the hell are they and how do you flash?
I just put Miui on my EVO. I really like it but there are some issues with Bluetooth and also voice messages not wanting to send or receive. Plus the front camera issue.
I saw some others flashed a different kernel to fix some issues so I was wondering how to do that.
Also mentioned was doing a Nandroid backup... what is that?

Take the zip you want drop it in your sd card use rom manager recovery and install new zip nanroid is under recovery mode as well
Flash a kernel- place the zip file on the root of your sd card [not in a folder], wipe you cache and dalvik cache, then click install zip from sd card, then select your file
Nandroid [a backup]- from the main menu, select backup and restore, click backup, done.
Always do a backup before flashing a kernel because it may not play nice.
Once you've got the basics down. Just start with one of Netarchy's (my preference) and try a few to see what seems to flow best with your phone. I've had the best luck with Nets 4.3.1 more havs nosbc. Good luck.
To wipe the cache and dalvik cache, is that listed under the recovery menu or do I have to do it some other way? What is stored in the cache?
Also hope I got this right, but I can only use AOSP kernels with Miui? I'm not sure what is different about AOSP. Is Netarchy AOSP?
Unfortunately, I don't believe Nets has any AOSP kernels. Sorry, I don't have a good kernel recommendation for Miui. I'm a MikFroyo fan, tried a lot of roms and kernels, but haven't given Miui a try. I like my 4G. Mik is fast and stable, so I've stuck with it for a while now. Depending on what recovery your using, to wipe the dalvik cache, you should have that option. In clockwork its under the advanced i believe and in amon its under wipe. Don't really know what is stored in cache, but any time you make a change or flash something new, always good to wipe the dalvik cache.
What is AOSP versus whatever else is used?
in the evo world, every rom you'll find is either AOSP or Sense based. Aosp roms are custom made roms built straight from android source. Miui and Cyanogen are the most popular AOSP roms. Sense roms are basically the rom sprint uses that people have hacked to make it faster/personalized.
Do the kernels have to be specifically for the EVO?

AOSP- Android Open Source Project ; closest to bare bones Android [Think Cyanogenmod]
the other is Sense- Think stock HTC Evo, roms like MikFroyo, Azrael, ect

I believe so. Make sure you're running a stock kernel with stock rom aosp kernel for an aosp rom.
Nandroid
Nandroid backups are performed in custom recovery. They essentially backup the entire "image" of your current ROM into the "Nandroid" folder on your SD card. The beauty of this is that you can take a nandroid backup, flash a ROM and, if something goes wrong or you don't like it, you can restore via nandroid and return your phone to a previous state.
No one has still answer his original question...
Android relies on Linux version 2.6(the kernel) for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack.
So basically, it is what allows for better management between the rom and the actually hardware. For example, your rom could manage how many applications are running and using up cycles of your processor, but your kernel will determine how your processor elevates to the needed speeds for the ongoing task. Kernels are important to keep your phone secure, stable and longer batteries

Need some help asap

ok well i just downloaded and flashed the chopsuey kernel and now when im rebooting, my phone only sits at the htc evo 4g screen.. someone PLEASE HELP.. i think my phone just got bricked
No problems mate,just pull your battery,replace it,when turning on hold your volume button down,when you entered the bootloader,scroll to recovery and wipe your phone then find restore/nandroid then restore your phone to your latest backup,hopefully you did back up,if not reinstall the rom again after you wipe everything,then next time set your CPU to a lower setting,then move up gradually.I hope this helped.
blah.. so new to this i didnt know i could backup through recovery.. thought it meant like my apps and what not =/ guess i have to wipe
I set my phone to high the first time and it did the same thing and of course i freaked,lol.After bricking your phone a few hundred times,you remember to do a backup regularly.
what rom are you using? Hopefully not a AOSP cause Chop Suey is a sense kernel.
well my set cpu wasnt working because i was using stock kernel.. all i did was flash the chopsuey rom and then i just hit reboot and i was stuck at the htc evo 4g white screen.. what did i do wrong?
i am using team nocturnals sense 3.0 themed rom. more specifically, shooterRLS_3.1

I am rooted. and i meant chopsuey is a kernel.. but the rom im using is shooterRLS_3.1.. im guessing i just flash the rom, and then the kernal and im done?
i just retryed and now its actually starting up so blah.. is it actually not compatable or not?
If its running ok,use it.
oh ok.. i dont want to screw up my phone.. so blah.. thanks for the help.. almost had a heart attack
Did you wipe cache and Dalvik before you flashed the ROM? If that ever happens again, wipe those then try to boot again. If it still doesn't boot, wipe everything and reflash your ROM, err, start over, but since it was just a Kernel, that would probably wiork
Whenever you flash a new rom, wipe everything (data, cache, dalvik, system, boot, .android_secure, sd-ext). Whenever you flash anything that isn't a rom - kernels, themes, mods, boot animations, etc - or flash an update to your existing rom then wipe cache and dalvik only.
Always make a nandroid backup when you flash a new rom. I don't nandroid for everything I flash, but if you're flashing a new kernel and it has been a while since you did a backup then go ahead and do another one. You can always delete nandroid backups to save space, but keep at least one on your SD card. Also nandroid before modifying system files, like removing system apps.
Always read about what you're doing before you do it.
I know you solved your problem, just pointing some stuff out that you may have missed along the way. Good luck & happy flashing!

True that. I keep 5 Nandroids on my phone at all times: Original Stock/Rooted. Stock/Rooted with updated apps +TB & GPS Status, Last good setup, Current ROM before I added all my apps, etc. and Current ROM after a fresh flash.

Jeeze, I feel like I take so many shortcuts...I only keep a backup of my CM7 latest, and currently ICS, incase I had to switch for whatever reason.
I keep all my apps up to date in tb so that alleviates that issue.
Well, it's not about apps. I like to have the barebones, stock/rooted all the time. The updated stock is for when I need to run the Sense Fix for GPS, or just updating profile/PRL.
The last Good Setup is obvious, as is the current good setup.
The bare bones Nandroid for my current ROM is in-case I screw up, I can go back to that and start over

Well that makes sense. If I mess up, I just go back to the last backup. xp Though neither practice is bad.

A few questions regarding install custom ROMs

hi, i recently got an ATT note 2. The phone I got already got Clean ROM 3.5, so I presume it is rooted, with custom recovery (TWRP when I checked). I am thinking of flashing to a diff rom and just want to ask a few questions.
1-do I need to run triangle away every time I flash to a diff rom?
2-since the phone already has a custom rom, I should not have to root it, am I correct?
3-If I want to install custom, ROMs, can I just put the ROM in the external SD and flash it that way (of course with clear cash, davik, etc as states in the rom).
4-I am thinking of playing with the CleanROM 4.2.4 or the ACE version? any issue with either one compare to the 3.5 that I am using now? any recommendation?
5-anything I need ot watch out before I flash it? I have flashed a coupole of time with htc phone and this is my first samsung phone so I don't watn to brick it.
thanks a lot guys, XDA rocks.

1. No you do not need to run triangle away usually only have to run it if you are going back to stock and may want to return the phone.
2.Nope it has a Rom you are rooted !
3.That is what I do when installing a new rom factory reset wipe davlik and cache and install you may have to fix permissions with some installs as well after installing.
4.From the bit I played with the new Clean rom it is very stable with minimum if any grief Jedi 9 is also a awesome ROM and my current fave.
5.Just read up lots before you do it follow every step they tell you to take your time it is easy just make sure ya know what you are doing before you start.
6.Enjoy they are a awesome phone !!
Thanks a lot for your prompt reply. It heped a lot. I will definitelycheck the roms. I am using 3.5 and it runs really good and hate to ruin it.

do a backup in twrp before flashing a new one, you can always come back
thanks for the info. That brings me to another question with TWRP, when I do TWRP backup, should I backup everything, modem, efs, etc. Also, if I use that backup and I do restore, does it restore everything, program, rom, setting, etc?
Also, if I want to flash the stock ROM, would that mess up my root, recovery etc? Do I need to do anything if I flash the stock ROM? From my past experience, sometimes, it is good to flash the stock rom once in awhile since that seem to do some sort of clean up and it also helped to keep the modem and such up to date.Probaby won't keep the stock for a long time but just thought I may flash it to play with it and keep the modem files up to date. Then flash custom rom. I also read that if I want to use triangle, I must be on stock rom or it will brick my phone, so I want to make sure before I start playing with diff roms.

This is one of nice features of TWRP... ability to backup/restore individual partitions. Android stores various blocks in different partitions. To name a few, System, Data, Modem, Recovery, Boot, Cache, etc. If you just want to backup your modem for example, just check the "modem" box (and I recommend naming the folder to something significant so down the road you'll know which modem it is). When you restore, that folder will only have your modem.. so you can restore a different modem without having to change your rom, (etc). Kernels are stored in the "boot" partitions.. again, if you want to change kernels, backup the boot partition and name it properly if case you want to reflash that kernel. Generally, after my first flash of a new ROM, kernel, modem, I'll create a "boot" backup, "modem" backup, and ROM (system/data/boot) partition backups. If you look in the TWRP folders themselves, you can see the blocks which are backed up... or will be restored. Hope that helps.

When I back up in TWRP, I usually just go with what is default checked off. You will not mess up your root unless you really really tried to. The last time I ever had to flash back to stock then to a custom was on my Xperia X10a... You should be fine flashing a new rom without having to go back to stock as long as you do a good wipe (Wipe System, Factory Rest, Davlik, and Cache is what I do only because it doesn't hurt... I've read you do not need to do all those steps but I do them nonetheless). Do not use Triangle Away unless you plan on returning your phone or send it in for warranty. Only then should you start asking questions about that tool.
The only issue that may cause SOME confusion (not too much but some) is flashing back and forth between a 4.1.2 and a 4.2.1 since the SD card adjusts to User settings (some folders open up for individual users on 4.2 but as far as my experience goes, I have not had any issues with it, I just needed to study my SD card after each flash).
So you should be fine... just do backups, rename them to make sure you know which rom belongs to which backup, delete the old ones from the RESTORE menu in TWRP in case you are backing up the same rom to save you some space (my backups take around 2 gigs sometimes EACH) and you should be good to go... Enjoy tweaking out on your roms!

Much appreciated for your detail explanation on the TWRP. I did a quick backup and selected all of the option and now I see the files in my external SD:
modem.emmc.win
data.ext4.win
cache.ext4.win
recovery.emmc.win
boot.emmc.win
efs.ext4.win
data.ext4.win
system.ext4.win
Quick question. If I understand correctly, the modem and efs is not ROM backup, so if I just want to revert to the rom I am currently running with all apps and such, I only need to backup system, boot, data, am I correct?
Also, is there any way that I can retain my data, settings, and apps, without re-download and re-configurate everything after I flash to a new ROM? I am thinking that maybe data will do such thing but not too certain. In the past, whenever I flash to a new rom, I always download all apps again from market and setup everything again, a bit hassle but that's how I did

thanks for the info/warning on the triangle. I read that it can brick the phone and also needs to be on the stock to use it. Also read that if there's too many counts, it may not work. I guess for now, I just won't touch it.
Since there's no 4.2 roms available (at least not what I have seen and want to play, CleanRom or Jedi as they are highly rated), I guess for now I do not have to worry much on the SD card issue. It will be safer I guess for now just stick with 4.1.2 until the kinks are worked out.
For the wipe system, factory, davlik, cache, do I do that before flashing it?watched a couple of video and instruction and they all have diff answers. Some people said do factory reset, flash, and then wipe davik and cache.
Again, really really appreciate all of the support guys.

Think of your Nandroid (TWRP) backup as a roll back to what you are comfortable with (check everything off so you do not lose a thing if you want) in case you find that the new thing you flashed isn't all that it was cracked up to be for you or something messes up. The Nandroid backup is EVERYONE's friend.
As for flashing a new ROM and having to start all over, I will use this as an example: I have two backups; one for Paranoid Android (4.2.1 AOSPA) and Clean 4.2.5 (4.1.2). When I originally flashed my stock to Clean, I must've gotten lucky by just wiping the system (ROM only and not a factory reset) and all my data transferred over just fine with no issues... but when flashing to PA, I had to do a full wipe then start from scratch (which was not bad if you sync your apps and contacts thru Google). Also, you might want to get another backup system such as Super Backup to back up your contacts and SMS messages (be careful with backing up call logs if you go to 4.2.1 ROMs because for some reason, things went wacky for me). Titanium is a good system to use for power users but sometimes, to keep it as simple as possible, count on Google at first for your app syncing (and if you get Amazon App Store, you will have to get that APK to download the apps from that store).
Anyway, from there (if you want to play with multiple ROMs) you now have a foundation. Dirty flashing (flashing a new version of a ROM you currently have without doing a full wipe... just in case you didn't know... for me, I just wipe System [no factory reset] then flash the upgrade) should be fine... again, I'm typing from experience because there are some people who do run into issues dirty flashing and is usually not supported by the devs unless you do a full wipe and flash. I have not had any issues whatsoever dirty flashing both PA and Clean versions.
As for methods of wiping, honestly they're all right... I just posted what I usually do when I want to do a full wipe. Only if you want to do a dirty flash, you won't have to wipe or do a partial wipe (I partial wipe e.g. Clean 4.0.5 to 4.2.5: Delete last Clean Rom backup through the Restore menu, Nandroid Back Up current working Clean Rom 4.0.5, Wipe System, Install the new 4.2.5, wipe Davlik and Cache (again, I do this just in case but some devs say it's unnecessary), then reboot and wait for the apps to reset... all was where it was when I left 4.0.5.

Quick question. If I understand correctly, the modem and efs is not ROM backup, so if I just want to revert to the rom I am currently running with all apps and such, I only need to backup system, boot, data, am I correct?
Also, is there any way that I can retain my data, settings, and apps, without re-download and re-configurate everything after I flash to a new ROM? I am thinking that maybe data will do such thing but not too certain. In the past, whenever I flash to a new rom, I always download all apps again from market and setup everything again, a bit hassle but that's how I did

Yes... if you're retaining your current modem and recovery... to restore a rom just as it was when you backed it up, restore boot (which has the kernel), system and data. One your second question, when restoring a different rom , it's best to always restore system/data/boot together. You can use TiBu to restore your user app DATA, and individual apps usually have their own backup files you can restore (like Nova/Apex launchers [which can restore your widgets], calendar, etc).
much appreciated guys. thanks so much. I think I got it. Will get ready to pick a good ROM and starts flashing.
one little thing, I saw this rom here: http://forum.xda-developers.com/showthread.php?t=2124182
it says stock rooted, does that mean that it is essentailly identical to what is found on the stock rom except that it will not mess up with my recovery and rooting if I use it to flash as oppose to the guide I saw online to flash to completely stock using ODIN.
Also, I did the unlock with what I found on the thread, would that mess got messed up when I flash to different ROM?

I have never used that rom so I can't say for sure. Try it out and see what happens. If you don't like it, restore your backup.

That rom is one of the most recent 7105 (note2 international) samsung firmware releases... supposedly better battery life than LL7 or LL4. It's the stock MA6 pre rooted (i.e., has SuperSU app and binaries included). No other features added like you would find with CleanROM 4.2.5 for example. It includes rom and kernel... so it will write to your system, data, and boot partitions. Whatever custom recovery you have now and flash this with will not be touched.
thanks again.
