Root The Complete Unrooting Guide for the Evo 4g

Well, it appears to me that you have no custom recovery, no super user, and you only have an unlocked bootloader.
I"m just wondering if you can just re-lock the bootloader? hmmmm....Ocn?

no need to re-lock it. it will still be watermarked. lets finish getting fully rooted first.....but that is up to shmooey.
 
(1st let me apologize for cross posting. I originally posted this to the rooting guide topic and then found this one specifically for unrooting.)


Hello everyone,

New to the forums and by no means an Android expert.

I've got an EVO 4G unlocked, S-ON, HBoot 2.18, latest TWRP, I put CyanMobile 5.1 on it a couple of months ago. Ever since it has functioned properly but I have been unable to flash any new ROMs or upgrade to any of the new versions of this ROM. Basically it has been stuck on this ROM and won't let me flash anything else. Even tried to change to Amon Ra recovery and couldn;t do that either. Last fall, when i first rooted, I was able to flash a couple of different ROMs but once I flashed this one it's been stuck.

There a couple of quirks in this ROM that annoy me so I've been trying to change it for a while now. At any rate, in desperation, I've tried everything and today have finally gotten to the point that it won't boot past the white HTC EVO 4g screen.

I am trying to follow the unrooting guide above but to of the links to files on TheMikMiks sight are broken. Can anyone help out with an alternative source for the flash_image.zip and the mtd-eng.zip files?

Until today this was just an annoyance but now i have no functioning phone and really need to try and unbrick it asap.

Any help or guidance is greatly appreciated.

Oh, if it makes any difference, I think I used a modification of the Taco root method found on XDA to unlock it.

Thanks,
Mike
 
Welcome cosmichippo:)

Are you wishing then to unroot the device?

I'll have to look into the broken links, sorry about that :o
Let me see what I can do.
Can you get into recovery or the bootloader screen at all?

Thanks for the reply Mike

Yes, at this point just get it functioning but I think ultimately unroot.

Yes, I can get into the bootloader and recovery. I've tried flashing another ROM since it started sticking on the initial white screen and it failed in TWRP.

Thanks,
Mike
 
I'll have a look at the recovery install method.

I've tried the multiple wipe thing and it says wipe failed usually on the second but always by the third.attempt.

Sorry I haven't recorded at what point the failures occur. I attempt again and report back but it may be a bit. I've a couple of appointments this am.
 
are you wiping dalvik cache, cache and data(or system) before flashing a rom? twrp never worked for me on my og evo....the earlier twrp recoveries almost bricked my phone.....so i have stayed away from them.

i have the files and will update the op when i get a chance, but i think it is not necessary to unroot.....you have all the tools to fix your issue without unrooting.

if you can try and switch to amon ra or smelkus recovery. i know you said you had issues switching in the past. lets try again and see what happens. there are several methods to switching, which one's have you tried? the rooting guide in the htc dev method has instructions on the various ways to get or switch recoveries, if you need more info.
 
Yes, I have tried wiping everything except the card multiple times. I just occurred to me that doing that complete a wipe and trying to repeat it might be the reason I have gotten failed wipes on 2nd and 3rd attempts.

I will try and us the method in the guide to flash a new recovery and report back.

Is there a current prefered recovery for the OG EVO?

Thanks so much again,

Mike
 
That did the trick! Well, I guess I should more specifically, flashing smelkus recovery Using abd from the PC did it. Everything flashes fine now and have switched ROMs.

I'm sure you hear often buy, you saved me thanks a million!

Still unsure as to why it wouldn't let me switch to amon ra before but am rollin smooth now thanks to your help.

Thanks again for your attention and help,
Mike

were you trying to do the PC36IMG method? if so, then the file needs to be named exactly or it will not find it.....also it needs to be on a sd card that is bigger then 2g.

but anyways, CONGRATS!!!!!!!!!!!!!
:party:

glad it worked out for you.

just remember unrooting should be your very last resort.........plus you have us;)

just curious as to what rom you picked out?
 
I had tried the PC36IMG method to no avail. It was named correctly but the flash would fail every time no matter how or what I attempted to flash. I had not gone back to the PC and flashing through abd.

I tried The Captain's rooted Stock 2.3 but was gonna ask for suggestions for a solid ROM with all functionality and superior battery life.

Thanks a bunch for any other suggestions,

Mike

well if you want sense then mikg3.11 is the best, but if you want to get away from sense then try aosp....deck's reloaded is probably the best rom out there for the og evo period. http://androidforums.com/evo-4g-all-things-root/618281-list-utilities-apps-roms-kernels-og-evo.html check out the staff picks for more suggestions.
