So I have a fully root Evo4G running CM6. I was flashing the nightlies but am going to hold off for a little while. The first stable is soooo good.
Only problem is lack of 4G, I am temporarily in a city that actually has 4G and I have never been able to use it. I am considering flashing the stock rom that has 4G on it, but I am quite sure that will break root.
If I perform a full nandroid, flash to stock, and them restore the nandroid when I leave the 4G area will I be able to get back to full root? I'm not sure if it will completely restore everything on the phone including root and custom recovery.
I know that the current stock doesn't have a root method yet, and 4G is NOT worth running sense again.
Any help would be great, thanks

I have installed Fresh Evo 3.1.0.1 and I want to try OMJ EVO 2.2 FroYo v2.1 to see if Wifi teather really works. I have backed up my current rom with clockwork recovery, do I need to do a backup with titanium backup for my applications?
Also could someone point me to a guide of how the switching roms process goes.
so I went a little too crazy initially with my new mytouch 4g. rooted, S=off(used VISIONary+ and ran the root.sh script), installed ROM Manager and flashed clockwork recovery.
Unfortunately, I've realized that there is a slight bulge on the left side of the device, where the 3 metal dots are. Also, GPS takes at least 10 minutes to get a location. I have had the phone for 8 days and should be able to just return it. To be safe I want to wipe/unroot it.
I have a 2 crucial questions I'd really like help with:
1. if I do a backup with clockwork Recovery (2.5.1.2) by booting into it select "backup and restore", then "backup". Is that a full nandroid style backup? and will I be able to flash that back to my replacement phone to get it back the way I had it before?
2. if I follow the instructions here http://theunlockr.com/2010/12/16/how-to-unroot-the-t-mobile-mytouch-4g/ (without the gfree part), will that revert my phone back to complete stock? with stock recovery and everything?
Just flash the stock nandroid found in the ROM Bible. Move it around alittle so it seems like you used it. They never check s=off if the complaint is cosmetic. I returned my MT4G twice now with s off. Just flash the stock nandrois tiger013 posted. Hope this helps.
well I performed my backup with clockwork recovery. flashed the file in my 2nd question (it looks like its brand new out of box, and has s=on) before I saw your reply.
I'll post back how the exchange with t-mobile turns out. I wonder how well the backup will work if I flash it back. hopefully 4g will work and the dang gps won't take as long to get a signal.
i had to replace my first phone, and i had made a backup. put my old sd in the new phone. rooted the new phone (made a back up just in case) and flashed the backup of my old phone. worked like a charm and even had my sms's from my old phone. contacts were all there, app's, everything!
one thing i don't know is if it will flash your old radio and that might give you problems??
thanks for the help. I got the new phone.
As far as all that screen mumbo jumbo: its a -00, made in taiwan. but looking at the data in the terminal, it is a 02 screen, and looks as good as the previous one from china.
my first mt4g, I was able to root quite easily using VISIONary and the root.sh script files for S=off.
This one, I could not get perm root with VISIONary, only temp root. Any attempts to permroot would lock up the phone until I pulled the battery (I waited 30 minutes each time before doing so) I was able to finally turn s=off using the gfree method. STILL can't permroot though. I flashed clockwork (while temprooting it), and now backing up the current rom. I will try to restore my backup from this morning. I hope that the radio doesn't screw up.
Will update when this finishes up.
and just finished the backup from this phone, and restore from the previous. it worked! I have 4g, root, working gps, s=off.
The hardware keys are also noticeably firmer too. the old ones were very creaky.
Nice! Gotta love clockwork!

I hope that this isn't a repost, I've searched quite a bit but nothing is exactly like what i'm experiencing.
Here's what happened, i'll try and make this short and to the point.
Got my new evo, rooted it using unrevoked 3 and got root access.
Loaded a few custom roms, no problem, finally settled on Calkulin's EViO rom. Everything was working great, 4G was perfect, blah blah blah, buddy with an evo told me that Cyanogen was the poo and that I had to flash to that as it was the best ever.
I download Cyanogen 6.1.2 from cyanogen's forum and proceeded to flash it to my phone after doing a nand backup on my current rom. I forgot to back up my RSA keys (didn't even know i had to in the first place) and after cyanogen loaded, I read the thread that states that flashing cyanogen make screw up your wimp key and that you should backup your RSA keys (crap!) before loading cyanogen. Well after reading this and freaking out, I went back into recovery, wiped everything, and loaded the recovery img of the last rom I was running on my evo.
Now my 4G doesn't work in calkulin (posted a thread about that a couple days ago), and I'm not able to load any rooms except for backups, a fresh copy of calkulin, and a fresh copy of cyanogen 6.1.2.
When i try to load a new rom (warm 2.2 for example), it'll load, but when i go and reboot, it'll sit at the white HTC EVO screen forever .. nothing will change until I pull the battery out and start the phone back into recovery. I can reload one of my old backup images and everything works fine again.
I've cleared all the memory, delvik cache, everything. I even formatted my SD card after backing it up and loading just the roms on there. that didn't help either.
Any help would be fantastic .. I'm completely floored as to why I can't load anymore rooms.
Also, i want my wimax back!
wow.. sorry.. i hope someone can help you.
but I would think, you have to call sprint. they may have the wimax info for your phone.. and how to put it back.
for my knownledge... how do you get the information RSA keys and wimax info.. so I can backup mine?
Here's how to backup your RSA keys

And issue is resolved.
amon recover > clockwork
4G is working now too. wewt.

that is great you got it done.
I dont use clockwork.

Glad you got it working bro. Just for everyone that is new who may read this thread Cyanogen DOES NOT break your 4G keys. Older versions of Clockworkmod Recovery will. Follow the how to backup your RSA keys before doing Anything with the EVO.
Just because 4G is not yet included in Cyanogen Rom's does not mean it breaks your 4g. In fact, thanks to some of our dedicated and smart devs there is an actual Alpha of CM 6.1.2 with 4g and from what I hear it works pretty damn good.
Anyway I just wanted to clear that up because I would not want anyone to think that CM Rom's break your 4G. I am sure the OP meant Clockworkmod Recovery, but said CM in a rush to try to figure out his problem.

thanks for clearing that up .. I'm not sure exactly what I read as I glanced over it and freaked out because I didn't want to ruin my wimax keys .. so thanks for the clarification.
I've been trying to install the 6.1.2 with wimax but I keep getting hung up on the white evo screen, as well as others .. I'm tempted to install CM7 and forget about 4G for the time being as I know toast will get it up and running in the upcoming months.
Hopefully someone can figure out the reason as to why the wimax alpha is hanging at the htc evo screen after installing the kernal.
This is my first post in XDA.I hope this is the right spot for this questions.
I have searched everywhere for the answers to this question before posting. I flashed to CM7 with the tiamat kernel awhile back. I love CM7 but was curious to see what other rom developers are doing.
I ALWAYS do a back up before doing any flashes. I backed up my CM7 and my base rooted HTC downgraded 2.2 through RM. I was able to flash to synergy with no problems and restore to CM7. I decided to check out MIUI over the weekend. I flashed it with no problem. Last night I wanted to try mikshifted-g and Supreme Sense . I could not install either of them . The both stalled once CWM started to install. It was stuck on updating. There were no errors. I took the battery out and tried to restore CM7 backup through CWM. The restore went as expect but when I went to reboot it was only the HTC logo. I took the battery out and went back to MIUI through CWM and the phone booted. I then did a restore of my original rooted 2.2 the phone booted. I tried to install the above again on a fresh HTC stock rooted phone through RM and still had the same thing happen.
My question, is why I am not able to flash any other roms successfully other than restoring to MIUI and stock rooted htc 2.2 ? Installing Synergy works !
I do a full flash of system,data, cache and dalvik cache. I am not sure what I am missing.
If I understand correctly MIUI is a GB kernel as well as the others so there should not be a problem of compatibility ? I am assuming I still have root ? My HBOOT does say S off and PG 06001. I will try downloading CM7 through MIUI again to see if it works through RM. Sorry for the long post. I wanted to give as much detail as possible. Thanks in advance for any help

My suggestion would be don't use ROM Manager to flash, wipe or make nands. Do everything manually through recovery. I've seen too many people have the same type problems when using ROM manager.
what I have noticed is the progress bar in cwm doesn't work with sense roms, at least it never did in the mikshifted roms i tried and they take a LOT longer to install than cm7. How long did you let them sit at the install screen with that blank progress bar? Try clearing all your data/caches then install a sense based rom but leave your phone alone for like 10 minutes while it sits at that screen with the blank progress bar that says mikroms or whatever it says (been awhile since i used one). It shouldn't take 10 minutes but if your phone sits at that screen for that long then you know for sure it isn't working. I pulled my battery a couple times before i realized that's what was happening. I read about it somewhere online.
I have tried both RM and CWM. Both have the same results. 99% of the time I prefer the manual CWM method. Sorry I did not make it more clear.
I did re-flash CM7 with no problem. I do let the rom flash sit for a while but I will try longer since you say it takes longer with the roms in question. I let it sit for a few minutes. That seems like it should be more than enough. CM7 is pretty quick to install as well MIUI like you said. I love the layout and features of MIUI but since I am in a 4G area seems to defeat the purpose of having 4G if you can't use it. To be realistic though 4G is spotty in Atlanta and I mostly end up for 3G or using my wireless at home. I will probably end up with CM7 again since I like it equally as much as MIUI. If I wait longer for it to install and it does not work is there anything I should be looking at as the culprit other than myself
you were right, it just took a LONG time to install. I thought I was losing it. It took over 5 minutes. I am used to the install times of the MIUI and CM7 . Thanks for telling me to wait a little long. It's always the simple overlooked things like patients
My advice is just make sure you do a FULL Wipe before flashing a Rom. Like on THIS GUIDE, saves headaches later. Aslo, as you've learned Sense Roms usually take quite a bit longer than MIUI ,ASOP, or most others. But yes patience is important .
I definitely do a full wipe . I used all the guides here to make sure I did everything correct. I did not realize that the sense roms took longer than the CM or MIUI. I love the layout of MIUI. I wished it at some point 4G was going to be a part of it but I understand why it will not be .
4G in Atlanta, GA is not reliable, at least on my shift with sprint. I hate to pay for a feature that I am not able to use on regular basis. It's so spotty here I have gotten used to it.
I was never a big sense fan but it seems like if you want to have the 4G feature you use either use CM or another Sense rom right ? I got the shift because of how solid it's built and many reviews favor the EVOs or Galaxy S on Sprint
Thanks for all the feedback

Well you might want to give [AOSP ROM] S.O.A.P. ROM (sense-ish on android phones) a try. Sounds more like what your looking for. It's by one of the Shift members here.
Ok guys after doing a bit of reading and looking around I finally decided to root my A500. As far as I can tell, everything went fine, but I have a couple questions.
First, I hope I didn't dink myself, but after downgrading to 3.0.1 and using Iconia root, I installed Acer Recovery Manager and used that to get CWM 1.3.4.
I did do the backup when Acer Recovery Manager prompted me to, but I didn't do a nandroid backup in CWM before flashing the Thor 14.2 rom...is it too late to do one, or this going to cause an issue?
And second, am I correct in my understanding that you can switch back and forth between different ROM's as often as you want, just by following the step #3 here:
http://forum.xda-developers.com/showthread.php?t=1205204
Any help on these questions would be greatly appreciated. Thanks!
I don't get what you mean by "is it too late to do a nandroid backup"
If you want to back up a copy of your device from before you flashed the Thor rom.. yes, it is too late. A nandroid backup is like a recovery point in windows, it is a carbon copy of your current system configuration. You can make a nandroid backup at any point you want, but it will only give you a restorable version of what is currently on your device.
And yes, those are the steps for flashing a new rom on your device.
The reason to do the backup BEFORE YOU FLASH your first rom .before you remove acer bloat ware. This is so you can go back to a full STOCK State . well other then root. But you can unroot as well.
so if you yes should do a backup. but it will be of the rom you flashed NOT The above near stock state.But you are not lost there are stock roms floating around. If you decided to take a ota and get back to stock there is still a way..
Hope this explains it better for you....
Do not get to flash happy.. Giggles..
Ok thanks for the replies...I don't anticipate myself needing to go back to full stock, as this Thor 14.2 seems to work great.
I'll go do a Nandroid on the current 14.2 and that way I at least have some back if worst comes to worst. Thanks again!

Glad you're enjoying it. I liked the 14.2 at first too, but then some odd problems started cropping up so I switched to a ROM from XDA and haven't looked back.
imo there's no reason to go stock any more, especially when you can overclock/underclock and get superuser access with a rooted device.
