HELP PLEASE - EVO 3D Stuck in Bootloop!

Hello All,
I recently rooted my EVO3D using the HTCDEV method because the bootloader was version 1.5.
Here are the steps I followed to root (sorry for the copy and past but I want to be as detailed as possible)
Files Used
su 2.3.6.3
TWRP Recovery
Steps Taken:
1)Take both the su.zip and recovery.img files and put them in your sdk tools folder.
2)Now do the following in ur command prompt, hitting enter after each command.
3)Code:adb push recovery.img /sdcard/And,
4)Code:adb push su-2.3.6.3.zip /sdcard/Then,
5)Code:adb reboot bootloaderUr phone will go to fastboot and should look like the after picture above. Now you can flash the twrp recovery, so do,
6)Code:fastboot flash recovery recovery.imgIt will ouput something like this,
7)Code:sending 'recovery' <5068 KB>... OKAY////writing 'recovery'... OKAY///finished. total time: 11.355sNow you have twrp recovery, so you can navigate to it. On ur phone, use the power button to pick bootloader, then scroll down to recovery and pick that. You will then be booted into recovery.
8)Here you can pick "install zip" and then pick the "su-2.3.6.3.zip"
It will flash, the you can pick "back to main menu", then "reboot system now"
9)You will boot back up and have working Superuser. I have had no trouble with Titanium Backup, Root Explorer, Quick Boot or any other app that requires root. Before you do too much, it would be good to go back to recovery and do a Nandroid backup. Always best to get one ready before you start modding anything.
All of this worked fine, and the phone was "unlocked."
Then, I flashed the most recent version of CleanRom (2.7)
Again, the phone worked fine, battery life was a little crappy.
I decided to flash Ziggy's kernel.I flashed the kernel simply by putting on the SD card, and then rebooting into recovery. This worked fine as well, but I noticed some of the buttons for example the menu popups displayed volume where it should have said more, or bluetooth options where it should have said preferences. so this is where the trouble started, I downloaded kernel manager, and flashed silverneedle through that program. Now, I am stuck at the White HTC Splash screen bootloop. The phone turns on and after 15 seconds reboots, and reboots, and reboots.
What Ive attempted:
I have done countless wipes and clears of the dalvik cache and cache
ive formatted the system and the date sections (advanced menu in twrp)
ive reflashed the rom after wiping countless times
ive tried flashing different kernels in recovery to no avail
factory reset and wipe havent helped
im not concerned losing the contents of the SD card
I need help because I already had two phone claims in the past 11 months, and if I claim another lost phone I will lose insurance for life with Asurion (sprint)
anytips or help would be greatly appreciated
i can provide any additional info

Similar situation, Not sure if you've already solved the problem but I'm going to copy paste my solution from another thread...
Hi, I'm not sure if this is the right place to ask but this is a preety derp question. I've gone across the internet and tried a lot of reflashing to repair my sort of "bricked" evo. What happened, was that I had a evo 3d s-on htc bootloader unlocked, with custom recovery -clockwork..anyways I had flashed the leedroid 3d 4.0 rom and It worked the only problem was my wifi, so i attempted to flash another kernel onto it, but I had accidently flashed "Rcmix" kernel which I later found out was cdma =.=. so now my phone keeps rebooting at the htc screen, it would just load up with the green htc letters, then after 10 seconds or so it'd reboot, and then begin the process again. I can boot into bootloader and recovery but whatever I flash doesn't seem to work including restoring my backups...and then the battery died so i couldn't even charge it or go in. But i managed to work out I could load into bootloader from the CMD and the furthest i've gotten to is to have the bootloader show FASTBOOT USB. SO I must be getting somewhere...? I did read that i had to load from the cmd and not just from power+vol down..but I'd appreciate any help towards restoring my phone to the way it is or at least before i flashed the rcmix.
Just a note tho I've tried factory resetting but all i get is that it loads into recovery at the bootloader options i dont get "clear storage" as an option and "restore to factory settings" and what not just boots me into recovery agian.
EDIT:
I Managed to fix the phoneeee!!!..just for future preferences and anyone else who has this problem...
I followed bits and piece of IL DUCE's advice to izzy spun, the important part was booting the recovery from cmd. I wasn't able to "erase recovery" But I tried just booting it,
First I would remove the battery,
Put it back in,
Plug the usb cable in
1. Type command, from your Adb/fasboot folder, "adb reboot-bootloader"
2. After that I made sure my bootloader said "Fastboot USB", and then I issued the command, "fastboot boot cwm-4.0.1.4-shooteru.img" or with whatever recovery you had..
3. From there I restored from my backups my original rom. Rebooting, and fixed.
--- and It worked. At the time I was on clock work recovery, i only had the Revolutionary recovery img. Cwm-4.0.14.-shooteru.img to be exact,
after going in there I just cleared the cache and davlik and then, proceeded to restore my backups (I'm not sure if it would've worked if I had re-flashed the leedroid or a custom rom)
and then I simply rebooted the phone, and it got back into my phones original state before leedroid (as I had Only backedup before then)....
Apologies for the lengthly post, but I guess reading does help, but I've been going nuts before I managed to fix this. Just thought I'd leave this post incase someone were to need this.

Same problem
Hi there. I just recently joined so excuse my noobness but i have a similar problem. I recently just rooted my evo 3d sprint with the the boot 1.5 and everything went well. I decided i wanted to overclock my phone so i followed zeemaxs way. Before going into the overclock procedure i decided to do the the RCMIX Evo 3d kernel v. 2.2.3 first so i would have better results when done with the overclock procedure.I bootup the kernel through the recovery mode on the phone butit failed to load so i just reeboted. After that my wifi and 4g stopped working. So i downloaded an app on the market called "flash image GUI" which lets me flash the kernels through the app. I flashed the RCMIX kernel and rebooted and now im stuck ima boot loop. I COULD just go back and back up to my old rom and settings etc...........but the problem is i dintmake any kind of back up or recovery i think. I know i know im stupid and an idiot but i just sort of panicked n ended up with this. If anyone can help please tell me.I do not want to pay for a new phone at full price. PLEASE HELP THIS POOR NOOB!!!!! X(

What your going to have to do is flash the original kernel you started with. thats why your in a bootloop

Similar problem
Hi everyone!
I have a kind of similar problem, so I won't post it in a new thread.
Yesterday I rooted my phone following this guide: androidforums.com/evo-3d-all-things-root/494212-complete-newbies-guide-rooting-flashing-evo-3d-roms-kernels-using-fastboot . html (i am not allowed to post links to prevent spam).
I unlocked it with htcdev and installed a custom ROM without getting any errors. After restarting the phone, it got into a boot loop; it showed the starting animations of htc and the ROM and then shut down again.
Here some more information:
-Evo 3d Europe gsm
-hboot 1.5
-s-on
-image version 3.28.401
-installed ROMs using clockworkrecoverymod (as proposed in guide)
I have tried these ROMs (all leading to boot loop):
ICS NonSense
Cyanogen Mod 10 – DisarmedToaster (v. 1.4 and 1.5)
Jelly Bean 3d (by Ubuntuz)
SAD 2.1 DEsenseX
I installed the ROMs by doing:
Connect device via usb > flash boot.img via fastboot (from pc) > clear Cashe/UserData/DalvikVM > install rom.zip from sdcard > reboot
I really don't know what to try
Any ideas how I could install a running Android OS are highly appreciated.
Thx for any help

Problem solved!
Ok, I solved the problem by simply relocking the phone and installing the stock ROM with the RUU.exe

RUU.exe
I'm glad someone else mentioned Relocking before running the RUU. I've read several posts be others that have actually stated that Relocking wasn't necessary but in order for the RUU to take you have to Relock. IF you get a chance check out CoolICS Rom and MeanRom both are pretty good.

Thanks all for the help, had to revisit this issue today.

[SOLVED] Bootlooped on stock rom after restoring

Hello, sorry for creating a 'HELP I don't know what to do!' thread, but I really am stuck now.
I had some Adrenaline rom for quite a while but today I decided to go back to stock because I was having some minor problems.
I suppose flashing stock went okay. I've got the stock recovery now, but the phone loops on boot. With the help of this thread I've figured this is because the previous rom (probably) used ext4 whereas stock needs rfs. That guy got it working by going through adb doing something that I can't even get to because adb doesn't recognize my phone. (I've tried installing drivers for adb but Windows doesn't want to use them because it thinks its own drivers are superior, even though I've uninstalled these, it keeps reinstalling them)
I also can't get CWM working. I've run the root update.zip and that seemed to go fine, but when installing CWM the screen just freezes and the phone reboots when pressing the home button.
I'm kind of stuck on how to revive my gio, any help is greatly appreciated.
Thanks.
Edit: SOLVED, thread may be deleted. Went to try flashing CWM through odin (ext4+rfs) and during the reboot phase my phone suddenly booted into the android OS.

[Q] Unbootable green and red pixelated screen on boot and CWM6/5 load

So just to state the lead up to the unbootable phone.
Condensed version:
Flashed to Bio360 (ONLY working rom that was running for me thus far)
After a week of use, phone would boot for 5 seconds until screen turned pixelated
reflashed but did nothing
flashed to ICS using download mode again and worked but with limited function as when I first flashed ICS before Bio360
flashed using CWM6 back to Bio360 but still same problem
now will not boot into CWM6 and gets the pixelated screen either way
WILL go into download mode so I tried a few more ROMs to hopefully write over whatever issue there is with the software but nothing
reflashed using ODIN the CWM to 5 and 6 but same problem (will not load to CWM at all now
tried a few more times in the precise order as the first time I ever got the phone working with Bio360 (STILL a messaged up screen)
More detailed account of things:
I originally tried updating to the ICS upgrade a few weeks ago but got stuck on the boot screen and other issues. I finally flashed the CWM6 and updated the rom via that to the Bio360 rom. I finally had a working phone again after countless hours of trying to get it working. I locked my screen after timeout to a pin number but actually found it was a pain in the behind so tried to switch back. However I used the 'settings' feature which was present on the home screen after boot that comes with the Bio360. Then I deleted the icon an could no longer find the one that I was originally using, but found the other newer icon in the applications. So I took the lock feature off. Though it did nothing and the phone still required the pin. I tried changing it etc etc etc and nothing worked.
So, I flashed the Bio360 rom again and tried to start fresh, only to find that most of the settings that I originally were using before the re-flash were still present. This lead me to believe the settings are not completely wiped and flashing through CWM6 does not do a pristine clean update. Then I read that I should have to clear any and all settings by factory reset, clear cache, partition or whatever other clear functions I found within CWM6. So I did that and everything was back in good order again.
That is until I woke up 3 days ago and found my phone 'bricked'. Not literally as I am told it is almost impossible to brick one of these. Upon rebooting the phone I found that it was booting to the Samsung logo and after about 5 seconds, the screen becomes pixelated with red and green colours, sometimes lines all over. The longer I leave it, the more the screen becomes a wash out.
So I tried flashing the rom again using CWM6 hoping this would fix, but the same thing occured. So I tried to use CWM5 hoping that would fix it but still the same. I tried flashing back to gingerbread, then ICS, then Bio360 as I originally did to get the phone working with Bio360 but the only thing that I can do now is boot into download mode. Anything else causes the screen to become pixelated and wil not boot past the messed up screen no matter how long I leave it.
I searched for other threads but only found threads based on a single large pixel or a physically damaged screen. However, the screen is still functional as when I boot to download mode or just before the screen becomes pixelated, everything looks great. Plus there was one time when I flashed to ICS I got into the blank screen with limited functional capacity as when I first flashed ICS and the pixelated screen disappeared. So this leads me to believe this is a software issue.
I believe that there is an issue with files being left behind that are corrupted or something similar but I cannot even boot to CWM in order to clear everything possible.
ANY IDEAS? I have explored every option that my limited understanding of software could.

picture of what it looks like
This is a crappy picture from my old phone of something like what it looks like.
https://plus.google.com/photos/111944628817208100010/albums/5793637254528885841
This is a capture after it was turned off even and I plugged it into my computer, displaying the battery charging animation, though turned pixelated after a few seconds.

My gut says hardware damage, like something inside the Tegra itself is fried, ESPECIALLY since it's happening sometimes while still in the bootloader (charging animation).
Try Kies emergency recovery. If it flashes successfully but still won't boot, or glitches out like this during the flash, you'll have to start the RMA process.

I am unsure if it would be a hardware issue though since the screen is fine during the 'download mode' and did boot into the stock recovery after a flash a while back, then flipped back to not getting past the Samsung logo and pixelating again.
Would I be able to load the download mode portion of the phone if it was a hardware issue?
I ask because my gut says the opposite.

flashing CWM 6 causes my phone to be unbootable and pixelated screen
So, I have tried to update the phone into whatever other ROM that I can possibly get working only to find out that after flashing a ROM that flashes the original recovery program included with Android, voilà! The phone works again and boots into the black screen with pull down menu. Back to square one for me.
Why would CWM6 be causing such a thing?

I'm on CWMR6 since the begining without any issue. Did you flash the touch or the non touch version ? Also whcih odin version are you using, maybe that makes a difference. The 1.82 and 1.85 are tested to be working fine with both cwmr 5 and 6. Also by reading your thread is seems you've never been able to flash through ICS one click, if possible try doing that.

I have been using the cwm5/6 touch and non touch. I have tried flashing them both. I have been using the most suggested version of ODIN 1.85 to flash. I do not think that it would make a difference as to which ODIN version I use, but then again I am quite ignorant on software.
The first thing that I did was tried the flashing using the one click method. I could only get to a black screen with the pull down menu containing the turn wifi on/off etc. I read that the problem may be permissions but I have tried that using the CWM when it worked and I was still stuck at the black screen with pull down menu. Without CWM I have no way of doing anything really since everything is in zip form and without CWM you cant use the zips.

Well then probably a logcat output to a developer would help understand the problem you're facing. Find some knowledgeable developer who can help you read the logcat and find the issue. Or post it here and maybe somebody would give you a clue.

I have the same problem, i bought mine in ebay, (i live outside USA so i cant get money back) my problem start when i try to install a apk, then, i try to restore with wipe in cwm (sometimes works, sometimes no) and eventually, only download mode work. I dont know what i do, but in one of my trys, ICS 4.04 works everything, but i was network lock,i try to downgrade to Gingerbread and the problem come back, i dont know what to do, i feel like i waste te money.
PD: I have the roger version
EDIT: I just flashed ICS from ATT And works, but i w ould like to root and i cant, every time that i flash CWM, the problem come back
EDIT 2: I use the one click to install ICS from att and works, its seem the problem is when i use a custom rom or the CWM, dont know why, its seems that is not hardware because ICS works perfect, but Every custom rom or CWM, cause the problem
Maybe is there a way torecreate all the internal partition, i dont know, or something like that, to make a clean install, I am starting to regret for buying this phone, maybe the problem is because is from rogers (a security rule maybe?)
Sorry for my english

I dont Know, its happen similar to me, but if i use ICS from ATT, everything works right
---------- Post added at 03:05 AM ---------- Previous post was at 02:45 AM ----------
Ok, i learned something, when a flash the Gingerbread version, there is a error while booting (the first time that boot lik recovery) , the error is can't access to /system/csc/ATT/system/
When i use the ICS from ATT, that doesnt happen, maybe that is the problem? i dont know, maybe someone can tell us what are these files

There is a working solution, http://forum.xda-developers.com/showthread.php?t=1953672 thanks to Rawr0w0,its works when you flash in that order, my phone is rooted and full working in ICS, i hope that helps you

Help with changing a 'i9082 Spin-off' recovery mode

So, Lately I've fiddling with my quite old 'spin-off' awkward phone. It's a "GT-i9063T" a different 'version' of the i9082 it's exactly the same, all the same specifications and physical size, screen resolution, everything. BUT (I'm not sure of the next statement since I had only one reference) -- The processor's name are different, even tough both have EXACTLY the same specifications.
And also, most importantly, the main difference between the two, is a useless "TV" function. It can capture (sorry not sure about that verb, I'm not American) average, analogical TV signal, and I never used it.
Since it's SO equal to i9082, i was like, FU*K it, let's use i9082 stuff! And, NOTHING, happened.
My first attempt was to normally odin-mode boot, and then change/flash recovery mode so i could install the ROM through there. The thing is, the TWRP (only recovery that I found who supported i9082) did nothing. I install it normally, no errors pops out, (it's almost instantly) odin even say it were successful, but when I reboot and actually try to enter recovery mode, the stock recovery mode is still there. My guess is: I got this spin-off of mine through a plan (those 6 months contracts and they give you a free cellphone) with Tim (the huge Italian communication conglomerate) And I'm guessing it's bootloader might be locked.
Then what i tried was: Flasihfy, the app crashes when i click to choose archive, then i tried to 'bootloader' mode and i couldn't find how to boot to it (no key combo neither ADB worked) and I think it's not a thing for Samsung devices.
But I know that, the fact that, my phone is a different model and i9082 stuff won't work on it just might be the answer.
So, help on getting a custom recovery on? Anyone? ;-;

PROGRESS! Actually, a verdict I think, I found out that, stock rom's replace the recovery on-boot, i haven't found ANY GUIDE mention that detail. So, knowing that, I tried again the TWRP for i9082, it bricked the recovery. The boot froze when I tried to access recovery mode and the red exclamation of death appeared, I even tried to let it load for a few minutes, try again, but NOUP, nothing. It did brick the recovery mode, then I let it boot normally, it did, replaced, my custom recovery and Voilà. Back to square one. BUT NO! I MUST CONTINUE I CAN'T LET MY DREAMS BE DREAMS, YESTERDAY I SAID TOMO... So I've started looking to see if I could find a recovery specific to i9063T, and I did, found one on a YT video, I flashed it booted into it and it worked!! So i've started the process, by trying to wipe/factory reset, then i found out the partition table of the CWR i found was messed up and it couldn't wipe the data. SO i reboot, let the CWR replace the stock recovery (it asked permission) and booted normally, restarted the phone and tried to boot onto it again, only to find out it had been replaced anyway ):
Veredict: i9082 stuff won't work because the partitions are different named/organized.

Stuck in Boot loop after weeks of normal usage

Hi.
I have a problem with my D855. My phone is rooted and runs the fulmics ROM. Everything was working fine, , on Fulmics 5.3, except than one day, I was using my phone normally and then it crashed. I saw the phone rebooting, but for some reason it got stuck. The phone tried to boot unsuccessfully until the "firmware update" went through, after what it reboots again (unsuccessfully) and so on.
At that time, I was able to access twrp, do some backup, and flash properly with a downgraded version of fulmics (from 5.3 to 4.1).
It was able to boot again and use my phone like before. Yet, after one month of usage, the same problem happened on version 4.1. The phone crashed and now cannot boot.
Any idea of where it is coming from? Should I go back to stock? Should I contact customer service?

What did you do before the phone crashes ?
I think you probably should flash the stock ROM and wait for an other crash... or not.

I haven't done anything special. I think that the first time I was playing on candy crush. The second time I was just looking at pictures in my gallery.
I was using the ROM without any tweaks or extra modules such as Xposed. Just regular use.
Update on my situation: I switched back to stock ROM and it seems to work OK for now (it has been 4 days). So I will wait and see if new problems happen. By the way, it was extremely difficult for me to get back to Stock directly from fulmics ROM. I tried several methods that I have found on xda based on LGUP or LG Flash tool without success. For some reason I was not able to connect the phone to my PC in download mode.
The only way that I found was to use a nandroid backup that I did just after rooting the phone and that was based on stock ROM.

You can also use the Stock rom flashable from twrp. So you can wipe the system partition and get a "better situation" than a nandroid backup that should be with an old version.
Or use this that has also root and other improvements.

At that time, I was able to access twrp, do some backup, and flash properly with a downgraded version of fulmics (from 5.3 to 4.1).
It was able to boot again and use my phone like before. Yet, after one month of usage, the same problem happened on version 4.1. The phone crashed and now cannot boot.
Any idea of where it is coming from? Should I go back to stock? Should I contact customer service?

Same problem here. Normal usage suddenly started to reboot and now it's stuck in boot loop

Coming from Fulmics too - stopped working one fine day.
Now, continues to boot-loop at the initial LG screen. Trying to get into the recovery shows me the the 'Factory Reset' screen, but beyond that leads to boot-loops again. Even the Download mode loops!
I'm at my wits end without a solution in sight.

You can also use the Stock rom flashable from twrp. So you can wipe the system partition and get a "better situation" than a nandroid backup that should be with an old version.
Or use this that has also root and other improvements.

Thank you for this advice. I was able to update my stock ROM after the Nandroid backup through LGUP, but your method would have been faster.
But anyway, I am waiting to see if I am stuck with bootloops again, using non-root stock version, so I can send it to customer service if this happen again.

Are you using Fulmics ROM as well? Can you have access to TWRP? I was able to connect to a PC in the recovery mode and to transfer files before flashing, in case you need some basic backup...

Silly question, but are you sure that you selected "Yes" when the screen asks you about factory reset? you have to press "volume down" and the "power button", since the default answer is no.

Yes, of course I was able to access TWRP successfully earlier.
Curiously enough, the phone boot-loops in regular startup, Download mode and trying to get to recovery. However, it doesn't restart itself and fall into a loop, while on the Factory Reset menu. Am I correct in assuming that the battery could not be the root cause of the overall problem? Because if it was, it would likely loop even on this Factory Reset menu as well as far as I understand.
Unfortunately, the phone restarts as soon as it lands in the Download mode so I cannot even restore to stock.
EDIT: Okay, weirdly enough it just booted and reached the homescreen before restarting again. What I did was let it charge to a 100% and tried booting while plugged in. Could it be the battery after all? Though this exact set of steps hasn't been helpful before.
