[Q] Evo4g Reboot Loop can't start recovery - EVO 4G Q&A, Help & Troubleshooting

I know there are a million threads about this but I haven't found the right files to work with what I have.
My Evo4g has:
Supersonic EVT2-3 SHIP S-OFF
HBOOT 2.10.001
RADIO 2.15.00.11.19
Two nights ago after I plugged in my phone to charge for the night it randomly rebooted and has been stuck rebooting on the HTC splash screen. If I try to go into recovery it goes to the same splash screen, goes black, back to the splash screen, etc.
I've tried to flash a new recovery but when I try to fastboot I get a failed message and I think it's because the recovery file I have may be for a different radio/hboot combo.
Any help you can give would be appreciated.
Thanks everyone!

Update.... still no success
I tried to do a complete reset on the phone by taking out the SD Card, coping over the PC36IMG.zip file I used when I first rooted the pone and doing the update. The update completed successfully but the phone is still stuck in the reboot cycle, even in recovery mode. This is the thread I followed when I first rooted my phone earlier this year howtoroothtcevo235withbootloader218.blogspot.com/2012/05/this-is-my-guide-on-how-to-achieve-s.html
If anyone has any ideas I would appreciate it. Right now I'm stuck and don't know what else to try.

Try a newer PC36IMG.zip, like the 4.54.651.1.

Thanks for the idea. I've tried "PC36IMG_SuperSonic_GB_Sprint_WWE_4.54.651.1_Radio_2.15.00.0808_NV_2.15_release_220182_signed" which changed my HBoot to 2.16.0001 but the phone is still stuck in the boot loop and I can't get into recovery.
My current system stats are:
HBoot 2.16.0001
Radio 2.15.00.0808
UPDATE:
So, I think I may be out of luck. From what I've been reading around the forums, if what I've tried doesn't work then the phone most likely has a hardware issue and is dead. I'm going to get a new phone but if someone has any ideas I'd love to resurrect this one.

Continuous Boot loop, Cant load Recovery, NEED HELP!

Ok, I'll try to keep this simple and informative.
I have been rooted with unrEVOked for months. Last night I flashed CyanogenMod 7 RC2. (I've posted this there too on their forums) Today my Evo crashed while using the app QR Droid, and now goes into a boot loop after the "htc EVO 4g" white screen. It loads that screen, then goes black, reboots and does this cycle until I pull the battery.
I can get into hboot. (v 2.10.001, Clockworkmod), S-OFF, updated radio last night when I actually could before I flashed CM7 RC2 to 2.15.00.11.19.
Here is where the problem deepens, and is very similar to this thread; Bricked Evo, and cant factory wipe. Help please
When I try to select Recovery, the boot-loop starts over; so i actually cant get into recovery and flash anything from the sd card it also does not give me any triangle bull**** or whatever, just starts the boot loop.
I have a card reader for my micro sd card; I took everything off of it and put an RUU on it, renamed it PC36IMG.zip, got into hboot, tried to update it and it failed, goes back to the boot loop. I believe the ruu was outdated.
Can someone link me to the most recent recovery image? I should use to get back to stock? I think that is my problem, the ruu is out of date.
Or any other input would be greatly appreciated.
Thanks
I tried this recovery image to know effect, when i reboot after applying update it goes back into loop; CANT POST LINK YET!

I attatched a PC36IMG of Amon Ra recovery version 2.3. You can try flashing that from the bootloader. I will also provide a link to the most recent RUU's and PC36IMG's. This link actually has all of them, old and new. Hope you're able to recover the phone dude. Good luck.

thanks, I have clockworkmod from when i unrevoked and had it updated via the CM7 rom manger last night, does that matter?
I tried that img you attached, it did not work, Im not exactly sure how to use the RUU's could someone explain what else I should do?

should'nt make any difference at all. I'm not sure how your initial problem happened, but you are not the first I've seen this happen to. Most that I've seen were recent, and were running CM7. Not sure what's up with that, but if you search the q and a section, you'll find a few similar threads. Very strange. I hope you ge it working again.
Happened to me and a few others a week or 2 ago. There was no fix that we found. Pc36img wont work, ruu won't work. U won't be able to do anything to get s-off to s-on either (in my experience.) Even tho u can get to bootloader, if its like what happened to me and a few others, ur bricked. I got mine warranty replaced (but they're still gonna charge me $125 for returning an unrecoverable phone) another guy threw his out his car window and they charged him $100 to replace his "lost" phone. Those are the only options I know of.

Phone is looping the Evo Splash Screen

I have searched and I can't get this too boot up.
I installed a fresh RUU and it updated it successfully but it still keeps looping.
I can get into HBOOT but not into recovery.
I was rooted running Decks 2.3.4 ROM with the Godmode kernal.
Any help would be appreciated.

Was everything working properly before you tried to run the RUU, or were you already having looping problems? Perhaps try clearing storage from your bootloader menu, then try to boot up again. If that still fails, then I'd try running the RUU again.
Some more info would be great, such as the following:
what RUU version did you flash?
what is your current hboot version?
what is your current radio/baseband version?
That information will determine which RUU you need to run.
If your looping at the splash screen (HTC Evo 4G screen) and NOT the actual boot animation, then it sounds like it could be a problem with your bootloader, possibly.
It does sound like you'll need to try running the RUU again, or running a different RUU.
Thanks for your reply.
Everything was working fine before this happened. I took it off the charger and booted it up and it started to loop.
Hboot is 2.10 and I flashed the latest RUU available from HTC/Sprint

So everything was working good, then you decided you were going to unroot? Do you mind if I ask why (out of curiosity).
So basically, you decided to unroot it. You ran the RUU, it completed successfully, you unplugged from your USB cable, turned it on, and the result was looping at the splash. Is that accurate? If so, I would try running the RUU again.
I'd probably even download a new copy of the RUU, just to be sure you don't have a bad download. Then try running it again and see if that makes any difference for you. I'll attatch a link to the RUU i keep in my dropbox.
http://dl.dropbox.com/u/16599118/RU...15.00.11.19_NV_1.90_release_161482_signed.exe
EDIT: I forgot to mention, that in order for you to run the RUU now, you'll most likely need to be in fastboot mode. So, boot to the bootloader, and select 'fastboot usb' from the menu. Once your in fastboot usb mode, try running the RUU. It should detect the phone and run just fine.
I wasn't trying to unroot. I flashed the ruu to see if I could get my phone working again after I saw it was looping the splash screen. I did the fastboot usb the ruu found the phone and flashed the new software and still loops.
Same thing is happening to me. I was on Deck's ROM except I wasn't trying to unroot. I put it on the charge then I noticed the White HTC Splash screen was on and off.
Now it won't get past it. I can get into the loader but not recovery.

Damn man, I'm sorry to hear that. The RUU is pretty much a last resort of restoring your phone back to stock when things go wrong. Since that is failing, there isn't too much else you can do. You can try running a different RUU, but I would most likely expect the same results you've been getting. There was a bunch of people with this same problem a month or two back, and there was never a fix found for it. The name of the thread was "boot looping and no recovery access" or something like that. Author of the thread was something like westibone. I'll see if I can dig it up for you, so you can read through that. There were a ton of suggestions in there. Good luck.

[Q] Help with soft birck

The incredible will go into hboot but the recovery, factory reset, clear storage all send it into a boot loop. It is S-off and should have cwm (the root was done by unrevoked) but I cant get it into recovery mode to fix the problem. the up vol + power will cause it to vibrate 3 times but the screen stays black.
I am use to samsung phones where I can just odin it back to stock but have little experience with Htc. Any help on reverting it back to stock or just help me get into recovery so i can flash a custom rom would be great. thanks
btw
hboot is .92
Radio 2.15.00.07.28
If you are s-off I would first try reflashing cwm thru hboot as a PB31IMG.zip
Here is the CWM 5.0.2.0 PB31IMG.zip
http://dinc.does-it.net/Recoveries/CWM_5.0.2.0/PB31IMG.zip
Just place it on the root of your sd and then boot into hboot (hold vol down and power) it should find the file and prompt you to press vol up to install. If that works then install the su binary found below thru recovery.
http://dinc.does-it.net/SuperUser/SuperUser_3.0.7.zip
thanks for the quick reply after updating with the PB3 file it still wont go into recovery mode, just the boot loop. any other ideas?
I would say your next step would be to do an ruu of froyo 2.2 wich you can fiNd here http://dinc.does-it.net/Stock_Images/3.26.605.1/PB31IMG.zip and if that dosent work I would try an ruu exe with your pc.
Thanks for your quick response, this phone is wack! I ran the ruu exe from my pc it did its thing and successfully updated the Rom but to my surprise when it rebooted it was stuck in a boot loop!
I had a similar problem a few days ago, and the only solution I found was to update CWM through RomManager. I'm thinking that the problem may have been caused by RomManager in the first place, which is why this is the only method that worked for getting CWM working.
You could try flashing an older version of cwm like 3.0.0.8 thru hboot. Mabey cwm 5 is whats causing your troubles. Or try flashing amon ra recovery.
Cwm 3.0.0.8

Can you get into recovery yet or are the hboot options still not working?
Mabey your hboot got corrupted somehow you can try reflashing it.
hboot 0.92
http://dinc.does-it.net/Hboots/Hboot_0.92/PB31IMG.zip
Then try flashing a recovery again and see if you can get into it.
None of the hboot options work. I have flashed all the files you have given me. and I have done the ruu exe of both froyo and gingerbread. they all say they have completed successfully but nothing has fixed the problem. Still cant get into recovery and it wont but up at all. Im not sure what else it could be
Im not sure then if none of those options work im at a loss of what else you could do. Mabey someone with more experince can chime in with some other options. Have you tried reformating your sdcard or using a different one? Thats the only other thing I can think of.

When you say "flashing" are you literally flashing these .zip files in CWM or are you renaming these files to PB31IMG.zip and installing thru HBOOT? There is a difference between the two.

He cant get into recovery thats one of the issues.
ya i guess not flashing just running the PB31 file in hboot. I think im done working with it though. Im doing it for some guy who tried flashing it from verizon to another carrier but it didnt work and it only goes into hboot now. but thanks for all your help especially cmlusco. I'm still open for ideas but It's not going to my priority anymore. I learned a lot about htc phones if anything

So the OP is S Off and can't flash the PB CWM file in HBOOT? Ccould be a bad file too. Make are you are checking md 5s

He can flash any PB31IMG file sucessfully but the phone will not boot and selecting any of the options in hboot leads him to a splash bootloop, and requires a battery pull. It's all above.

I have flashed the pb CWM file no luck and also the other recovery (cant remember the name)
I also tried flashing th pb hboot file no luck
I flashed the pb ruu froyo no luck and also gb no luck
i then tried doing it through my computer using stock froyo exe and also a gb one with no luck (In every case the phone said it was "successful" in updating the roms and/or the recoverys)
But nothing ever changes it will only boot into hboot but nothing works in the hboot everything just sends it into a boot loop on the white htc screen

Thats probably the issue it was attempted to be switched to another carrier wich is a fairly complicated process. He may have changed some settings below rom level that cant be fixed by flashing an ruu. Im not sure if there is a fix with qpst or not but if there is I have no clue how to do it.
Been seeing some odd issues lately. I had a problem, and it would just go to a black screen and vibrate five times.
If the USB was plugged in to my PC, it would boot and operate fine, as soon as I unplugged it, it would crash again.
Check this out, it may be related.

I've been having almost this exact problem and have been working on it since 5:30 last night. As my phone is also my modem, I am currently at the library on wifi... FML.
The only difference is that I did not try to switch carriers, I was just using my phone normally and then yesterday morning I had a bunch of FCs, and yesterday evenings began the boot loops when I unlocked to make a phone call, again, FML.
The timing is very bad, only about two weeks till my new-every-two. Please help, I need my phone and don't really have the money to spare for a new one.
Thanks in advance.

booting loop

My htc evo all of the sudden it doesnt want to start it just staying on the htc white screen and then vibrates and it restarts itself I tried installing a ruu rom and sitll the same, tried to install a recovery app and it wont take it I get a message saying that the image is invalid. Plz someone help me I havent slep and been looking and looking and I havent found something that can help me with my problem
Heres some info from the Hboot screen

any ideas will help
Same prob
Have you had any luck? I'm in the same boat, I've tried just about everything... I sold my phone to someone and they tried installing muiu rom and it quit working for them and they sent it back to me... And now I just want to get it working so I can use it and sell my iPhone and get a new android!! I hate the iPhone.
What exactly were you trying to achieve switching RUU's?
did you make sure it was for phones that were not rooted?
I havent had any luck and well I tried the Ruu that it wasnt rooted and it went all the way but the same thing keeps on happening
I am having this issue as well, about 12 hours after switching roms to cm9 nightly (unofficial) from the roms section, everything was working just fine, all was well. I had spent some time getting the rom set back up the way i like it, and had finished, while waiting in line at a restaurant I opened a bookmark from ics browser plus app and the phone rebooted itself. it just loops through the white screen, goes black, and then back to the white screen. I can get to hboot, but not to recovery, selecting recovery just goes back to the loop. I tried clearing user data via hboot, I tried reinstalling recovery (both amon-ra and twrp). the recovery installs ok according to the screen, but then trying to go back to recovery causes the loop to return. I do not know what else to try. (in my case, the phone does still show s-off and always has throughout the problems)
Any ideas or help would be greatly appreciated.....

You're gona ned to get to s-off sot hat adb and mount the system if needed. Since you have the 2.16 bootloader, head over to revolutionary.io to get to rooting tools.
UPDATE
After trying different things now my HBOOT says 2.18.0001
Radio 2.15.00.12.19 and at the top it says unlocked, how can I S-off if i cant go inside the phone?
Now you're S-Off, flash a recovery and see if you can into Recovery and flash a ROM.
BTW, what ROM were you using when this started?

[SOLVED] Bootloop with no access to recovery (S-OFF)

SOLVED. THE PHONE IS BROKEN AKA HARDWARE FAILURE
Hi,
My old Desire had been sitting in my desk for about a year since i bought myself a Galaxy S2. Today, I decided to try it out. Charged the battery first and then tried to boot it. Well, I got stuck in the splash screen. The phone had been working normally the last time i used it (maybe 6 months ago?) so i thought it was weird. Then I tried to boot it into recovery, and got again stuck in the splash screen. HBOOT came up normally but after pressing the recovery button the phone just made the boot vibration multiple times and then was stuck in the splash screen.
What I have:
- Alpharev S-OFF HBOOT: bravo_alphaspl-oxygenr2.img
- Oxygen rom (don't remember the version but i have the zip on my computer): update-oxygen-2.1.6-signed.zip
- My current HBOOT screen shows the following:
--- AlphaRev ---
BRAVO PVT1 SHIP S-OFF
HBOOT-0.93.0001
MICROP-031d
TOUCH PANEL-SYNT0101
RADIO-5.11.05.27
Aug 10 2010, 17:52:18
- AFAIK the phone is the older AMOLED version (if that matters)
- I have a working ADB
- I dont have a goldcard
What I did after noticing the problem:
1. Read the sticky which told me to reflash my recovery.
2. Flashed the CWM 2.5.0.7 recovery via Android flasher. The program said it was successful but my phone was in a bootloop again without access to recovery.
3. Flashed the Amon Ra recovery via Android flasher. The program again said it was successful but the bootloop persisted.
4. Flashed both of the recoveries (one at time of course) via the adb fastboot command. Again, it was supposed to be successful, but the phone STILL was in the bootloop.
I thought the sticky explained my situation perfectly but apparently this is not the case
I have also a RUU lying around:
RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00. 32U_5.11.05.27_release
But I was hesitant to use it as I have the custom Alpharev HBOOT which might cause problems.
So what should I do now? I appreciate all advice.
Re: Bootloop with no access to recovery (S-OFF)
In my sig you'll find a thread with how to install 4ext recovery through pb99img. Check it out.
I DL'd the PB99IMG.zip file for the recovery and put it on my SD by moving the SD to my other phone and connecting it to my PC.
However, when the HBOOT searches for the PB99IMG.zip, it only says "No Image!".
Re: Bootloop with no access to recovery (S-OFF)
Are you sure you didn't put it in any folder?
Then, again in my sig, you'll find a partitioning guide. The first part of the guide will help you install a recovery. Try it.
Yes, I put it right in the root of the sd card.
The partitioning thread in your sig has a few methods of installing the recovery. But i have already tried them and for some reason they fail. I have now tried the Android flasher method, the ADB + Fastboot method and the PB99IMG.zip method. I have no clue why these should fail like i have described.
EDIT: Looks like I cannot run the RUU either. It says it failed to detect the device. What on earth could be going on when EVERY possible way of reinstalling the recovery fails? I was starting to think that maybe there was something wrong with my USB connection/drivers or ADB so I made a test and flashed another alpharev HBOOT (their bravo stock one: bravo_alphaspl.img) and the flashing procedure worked. So at least my ADB is working. Still no idea why the PB99IMG.zip just won't work... looks like my phone defies all these guides available here.
Update:
I downloaded the 2.3 GB RUU from the sticky topic. Suprisingly enough I could run it, it detected my device and went throught the whole RUU process without a single error. I booted the phone - and was again stuck in a bootloop. Went to HBOOT, chose recovery (the RUU should have flashed the stock recovery) but no, I could not get into the recovery. Instead the phone was again stuck in a bootloop. So I still cannot get into the recovery. The only thing that changed was the splash screen I was stuck on... (I had a custom splash, now it's the stock one)
I then formatted my SD, put the 4ext recovery PB99IMG.zip there and booted into HBOOT. This time It found the PB99IMG.zip. It asked if I wanted to update, I pressed yes and it went through it without any error. When it asked if i wanted to reboot, i pressed no, navigated into recovery and pressed the power button. This should have taken me to the 4ext recovery i just flashed successfully. And guess what? Bootloop again...
So after all this, I still do not have access to the recovery. I just get the bootloop every time. I've whacked around with android phones (mostly Galaxy S2 though) quite a lot but this far have never seen such a persistent problem which just evades all (for other people) working attempts to fix it. The procedures work exactly as described and give me no errors, but in the end the issue still persists: I cannot access the recovery because of the bootloop.
I was starting to wonder if it could be hardware failure causing this? Just a wild guess but the phone has been sitting in my desk for almost a year... I didn't change anything in the software. The only thing that comes to my mind is that the memory where the recovery and rom are stored is somehow corrupt. This would explain why I cannot get into the recovery even though i have reflashed it successfully multiple times. I also can change my HBOOT and splash screen.
Does anyone have any ideas left?
Re: Bootloop with no access to recovery (S-OFF)
Are you s-on now?
Yep,
At the moment i'm S-ON with the 2.3 RUU from your sig. Bootloader is 1.02.0001. I flashed the RUU from the PB99IMG. No errors. Still cannot get to recovery.
I then opened the phone and removed the mainboard but i could not see any damage at all. No burns, marks of water damage etc.
Re: Bootloop with no access to recovery (S-OFF)
As weird as it sounds, try putting the phone in the freezer without the battery for 10 minutes, then try to boot.
You are pretty good, man.
CASE CLOSED
Explanation: after putting the phone into the freezer for some time, I tried to boot. It booted normally to the ROM. Wifi worked, I could use internet, setup my settings etc. After 10 minutes the phone rebooted into a bootloop. This proves that the problem always was a hardware one, and this is why any software fixes couldn't solve the issue. Because i don't have a freezer in my pocket I can safely say the phone is broken and I can throw it away.
Thank you!
