Root Most hard to figure out bootloop I've experienced or read about.

do I understand correctly that this may be an issue with the version of radios? And the newest version is the suspect?

I upgraded to the new radios but haven't seen where it did me any good, or bad, for that matter. I wonder if it would hurt anything to flash older radios back to my phone.

I have heard of the Sprintlovers rom that i seem to understand also flashes your radios. Is that correct? What version were they in that rom? would it be a problem to flash that rom at this point? would it change my radios to an older version again?

that being said, if I understood correctly, a rom CAN change your radios. I am sure these CM guys are way more knowledgeable than I am, wouldn't they know if their code had the potential of messing them up?

What would be the pros and cons of flashing older radios?
 
So what happens if you change the splash screen and then get hit by this bug? You're screwed right? It's a dead giveaway that your phone was rooted at some point.

Ok, reading through this thread has me scared. Thanks to the OP for letting all of us readers know what happened and how you got a replacement.

But now I am thinking the same thing MizzouBrent is -- I've flashed a different splash screen as well. Would it be prudent to flash a stock one, or since we flash those in bootloader/as PC36IMG files, can we hope to be able to replace it without getting into recovery if we hit this bad luck?

I mean, I should be prepared if this is a CM issue, because you know I won't be able to resist flashing CM9. ;)
 
But isn't MIUI based on CM? I know I've seen that debated back and forth, but I think I've seen more chatter confirming that rather than denying...

I'm not sure if it is or not. Correct me if I'm wrong but If MIUI is based on CM, than I would think it would have Wimax working, wouldn't it?

Well, I'm no expert, but what I've read is that the Chinese company that makes MIUI took their base from the original CM7 (for the Nexus line, etc -- not for the Evo), and never went on with the WiMax versions that were later made (no reason to, since there is no WiMax in China. Our Evo version of MIUI is ported over by a kindly American dev). But since it's closed source, there isn't certainty on that.
 
but come on, though. i may sound like a dick, but getting a replacement evo doeznt really fix the problem or go towards fixing this issue, does it?
The unlucky few who simply can't bring this fon to sprint(such as myself) are still interested in finding out what can be done.
i started a thread on this exact problem n never found a solution.
now im on da latest ruu, stuck on s-off, but able to change splashscreens, etc, but da damn fon just won't boot :'(

You don't sound like a d*ck at all, your frustration is totally understandable. Unfortunately a real solution seems to be lost on everyone. New threads like this one (and this one) seem to pop up every week... wish I had a real answer for you...

At this point Nu, the only solution available is to get a replacement. The problem seems hardware related and if that's the case, there's nothing we can do on our end.

I hope in the near future a solution (maybe preventative maintenance) will be available to us, but until then....
 
Andy was on miui when his went down. Really sucks for all that had the death boot strike their piece down. I'd cry...seriously weep like a little girl.
 
By all means if there was a real solution to the problem that was known about we would provide it, but at this point theres nothing you can do but get another phone
 
well, i DID use this useless evo for something

my lil bro not known for taking care of much, so he ran his breaks past metal to metal ans so the caliper pistons popped out, break pedal to the floor.
so it was late, on a Saturday night with no light when I remembered that i had a bricked evo!!
used the splash screen light to shine my way through replacing 2 front rotors, calipers a master cylinder.
did notice sumptin, tho
b4 it'd turn on the led glowed faintly red for like a split second b4 it powered on...
anyone want sum evo parts?
 
I remember hearing about this a while back. Scary. I'll probably be leaving CM7 because my paranoia is increasing.
 
there are plenty of cm7 users who never had this issue and there are plenty of sense users who experience hardware failure. You just never know.
 
Yeah, and I've been on CM7 (this same install) for several months. But I don't know about temping fate like this lol.
 
Well, I have been reading alot about this to and it has been happening to random CM7 users but it has happened to others also, maybe not as often but it has. I to am a bit nervous I have CM7.1 on and I love it and the other day it got hung up for a sec and rebooted and I thought Uh-Oh but it came back up just fine and now everytime I am gonna reboot I get nervous.

My question would be how many using cm7 are having this problem, and how long had they been running it? Was it CM7, or CM7.1 or both? Had you experienced any other problems, however minor, before hand?

My experience in telecommunication and sat. communications, in the past has shown that all soft loops(loops caused by software glitch i. e. ROM or Kernel, even stubborn ones) are fixable or can be unlooped. Here i would question the kernel before the ROM since kernel control voltages and voltages control switches and switches allows things to flow etc. etc. Now why I would question the kernel is voltages, this could cause spikes or undervolts that the hardware may not like, though it may tolerate it for a bit it can be bad in the long run. That is one reason why I would ask how long were you running before the loop?

An example of a very stubborn software loop existed in Direct TV cards back in 2002. Actually DTV sent down a code to put hacked cards into a loop though it affected some legit cards to,. The cards would not go past the boot sector. DTV did this in hopes of catching hacked cards from those dumb enough to send them back for repleacement. They could get them unlooped and retrieve the code off the cards therefore also helping combat the hacking of the cards. The solution was like a brute force hack. The cards had to be bombarded with different data sequences or hexadecimals which eventually cause it to pop.

I'd be interested in buying the bricked/bootlooped phone to play with it.
 
Sorry don't mean to ramble on but here are a cuple other things to consider. First I have noticed CM7.1 loads its own kernel, Does CM7 also??

Second, those that have gone into loop, how well did they wipe the system before they loaded?

Had they gone from a sense ROM to CM7? Had they continually been changing ROMs or Kernels or messing with Kernel settings?

Had they been using various scripts or not? Downloading numerous apps??

Those with the problem should share all info, there might be one tiny common thing that could give the developers a hint to a possible fix as long as it is not a harware problem.

There won't be a custom splach screen, just the white HTC EVO 4G over and over. The only way someone would know you were rooted is by s-off or seeing the red revolutionary. That's why it's crucial to get s-on before taking it in to Sprint;)

I'm not totally sure if the radios or wimax or NV.... changes causes the death boot. I'm just curious as to what radios people were on so maybe we can pinpoint the reasoning for the death boot. If people remember Virus's early Kingdom rom required to flash the 1.77 PRI, maybe if we can figure what's the cause for the death boot and if there's any correlation to the radios or if it's sincerely just bad luck:eek:

No this issue reared its head before the current radio version

probably true but it seems that the death boot is rearing it's ugly head more and more often. Again, that's why I'm curious if this could be something more with the radios..... and not the rom.

Ok, reading through this thread has me scared. Thanks to the OP for letting all of us readers know what happened and how you got a replacement.

If the death boot rears its ugly head, unfortunately without a known solution, there will be nothing you can do;) So......flash away:)

You can't change the splash screens can you? I don't think this is possible without a working recovery;)

Andy was on miui when his went down. Really sucks for all that had the death boot strike their piece down. I'd cry...seriously weep like a little girl.

Thanks Granite:D yes, I was on MIUI. I did weep for a little while but after I got my replacement, I rooted it within a couple of hours:p

By all means if there was a real solution to the problem that was known about we would provide it, but at this point theres nothing you can do but get another phone

+1
No known solution to the problem at this point:(

I remember hearing about this a while back. Scary. I'll probably be leaving CM7 because my paranoia is increasing.

I wouldn't be too concerned but I'm like you, I will probably NOT flash MIUI anytime soon. But I will be flashing ICS AOSP roms so hopefully the death boot will not happen again;)

there are plenty of cm7 users who never had this issue and there are plenty of sense users who experience hardware failure. You just never know.

My guess is that the death boot is affecting very few phones but again I would like to know if there's any sort of correlation to death boot to the radios. Also, I haven't totally ruled out the sbc kernel but........;)

Well, I have been reading alot about this to and it has been happening to random CM7 users but it has happened to others also, maybe not as often but it has. I to am a bit nervous I have CM7.1 on and I love it and the other day it got hung up for a sec and rebooted and I thought Uh-Oh but it came back up just fine and now everytime I am gonna reboot I get nervous.

I believe the sbc kernel that I was using still could be a possibility but who knows. You are more than welcome to have my death boot phone but if you have any suggestions as to what else anyone can do let me know. I will be more than happy to try anything. I would love to find the solution to this death boot issue;)

1. CM7 and CM7.1 has the same kernel;)

2. Believe me, I wipe everything before messing with a new rom

3. I don't believe going from a sense rom to an AOSP rom would cause the death boot issue but who knows

4. Changing roms and kernels? Are you new here?:p:D Flashing roms and kernels is the business of a rooted phone:)

5. I didn't use any specific scripts at the time. 10/14 MIUI build with the Tiamat 4.1 sbc kernel.

6. I usually have around 35-40 applications installed on the phone

7. I was on the latest radio, wimax.... from Calkulin's thread on xda.




So to sum up, I don't know a solution but I will gladly take any suggestions as I still have my death boot phone and I'm continually trying things to try and find a solution;):D

I was running CM7.1. The only problem I'd been having beforehand was occasionally around once or twice a day my phone would randomly reboot, it happened somewhat more frequently the closer my phone got to being death'd, so if that's happening to any of you, proceed with caution.

EDIT: I think Sprint will want my phone back when I get my replacement, but if not I'd be happy to send it to you.
 
I know flashing new kernels and ROMs is what happenends here. :) My thing is sometimes you get comfortable and laxed in the process and don't pay as close attention and make a mistake or change in the process. Even the best make mistakes, it happenes. First thing I learned when I started learning about computer and electronics was that 99% percent of all problems are caused by the user. The other 1% is split between software/codes conflicts or hardware malfunction. Now in saying this I am not implying anything about anyone. I am suggesting it could have been a minor mistake or step out of order, though i am not stating that to say it is for sure. Just trying to find possible causes. One code or software conflict could send it into a loop. That is always a risk in flashing that past little bits could hang around and cause problems, so that is why I ask about the wiping. Also again there have been issues with ClockworkMod not wiping properly. So just because we think things have been deleted doesnt really mean they have been deleted.

One other question, did it do the random reboots from the beginning? Or was it after getting it runing and making any kind of change? So did you flash or load anything after falshing the ROM?

I am interested in getting a bootlooped EVO G4 to try things on if anyone has one they do not have to turn in. Contact me! I love messing with this stuff.

Hopefully a solution can be found so this can be a thing of the past, though new problems will always arise.
 
We had one of the guides here come down with the same impossible bootloop problem, and if THEY aren't wiping correctly.... we're all in trouble

;)


I honestly think its not a user issue. Its got to be software/hardware related with cm7/variety's of it
 
I really think it's a hardware issue. If it was strictly software related, it could be erased or what have you, but it seems to me that if you can't load recovery or boot the phone at all, something with the phone is going bad or the Nand is corrupted or something. So I don't think a wiping process or something like that is causing it.

My original Evo had the problem where it would reboot randomly and eventually it got worse and worse. It was clearly heat related and something in the hardware failed. These phones are complex enough that they are going to fail sometimes. I have no idea what the Evo hardware failure rate is, but they're obviously out there. And seeing some posts in a death thread on XDA or this forum shouldn't scare anyone away from trying out different roms or radios because there's no clear link to put the two together. For every phone death we see on here, there are probably tons of others out there experienced by people running stock everything with non-rooted devices. We are a small fraction of the overall Evo usergroup, but a very vocal group.

I guess what I'm getting at is that I hope that issues like this don't scare people into exploring new things with their phones, because it has still affected a very small portion of phones, even when just looking at the rooted devices.
 
There won't be a custom splach screen, just the white HTC EVO 4G over and over. The only way someone would know you were rooted is by s-off or seeing the red revolutionary. That's why it's crucial to get s-on before taking it in to Sprint;)

Actually I do have a custom splash screen -- I long ago replaced the white HTC Evo 4G one. (for awhile it was just a pic of the android guy, now it's a black screen with "HTC EVO 4G" in white text) -- so the question of should we reverting to the stock white one is still there... (unless you're saying getting S-On somehow reverts the splash screen?).
 
I was just wondering, but what if you did a
Code:
dd if=/original/evo.dd of=/where/the/evo/is/connected
Would that do anything? I'm sure it'd have to be mounted the right way first (IE: not usb mode), but if it was software, that should write over it right?
