I chose CWM because I've used it before on a Galaxy Nexus and an S3 and it has been reliable.

I will install Cyanogenmod as soon as it goes to Stable for the M8. I have it on the S3 and am over-the-moon happy with it. However that could be a year.

Might wait a day before I try flashing TWRP. See if I can discover more, or if anyone has an insight to offer. I mean, why would it boot when you plug in the power cable?! Too strange to not be cautious.

It seems like it's an old issue with CWM though on various devices.

HTC Desire S same problem as you also CWM recovery.
Desire Z same problem also with CWM recovery.
Desire HD same problem ALSO CWM.

Don't know if there is a problem with CWM and HTC devices maybe...Those 3 are all for HTC devices. Though doing a google search you do get the same problem with different manufacturer phones also with CWM

wow! Clearly the issue! And it seems changing recoveries fixes it. Will try in the next hour.

what was the search phrase you used? All I tried returned irrelevent results, though mostly I was using G not XDA.

As my father used to say, your blood is worth bottling (its a compliment).

thankyou!

https://www.google.co.za/search?q=wh...w=1920&bih=979

Tossed in plenty of keywords into google, of course doing it normally gives a lot of results from other sites too but I just decided to narrow it down to xda(Most sites refer help questions to xda anyways so...)

I think it's better to use Google for searches anyways, it records info from a lot of sites. XDA works on a "keyword" basis it seems and most people when making threads don't really add any keywords to it so finding it is difficult. Heck, I even had issues finding HTC__622 in a thread where I knew for a FACT HTC__622 was mentioned at least 4 times, the results in xda itself turned up nothing.

I didn't even bother to try and search within xda for this issues, went the Google route and narrowing it down to xda, much better

Back to the issue though, it would still be interesting to know what actually causes it to boot into recovery when it gets plugged in, it's strange and I'm curious about it. I also think flashing either Philz or TWRP should help, there are quite a few people on here using Philz and I can't recall an issue like this being mentioned before so perhaps it's not a problem with Philz.

Thanks. I did try an XDA search from G, but you are just better at it

There is code that gets executed when you plug in the power cable:
it shows the battery charging.

The battery charging icon that is showing just before boot into CWM recovery is different from the normal battery charging icon (that I can see when I have settings /power / fastboot on).

I wonder if CWM changes that code? If that is the case, flashing TWRP might not fix it - will soon know.

Flashed TWRP
(openrecovery-twrp-2.7.1.0-m8.img)
much healthier but not completely normal.

Now, when I power-off,
1. initially this funny black/white battery charging logo appears
with words in red at the bottom like:
Quote:

This build is for Developement Purposes only
Do not distribute outside of HTC
without HTC Permission...

2. Then the normal green battery icon appears
3. but then the TWRP screen appears and disappears.
4. For about 2 secs the TWRP screen may flash back briefly
before returning to the green battery icon with the backlight.
5. Then it settles on the green battery icon,
and the backlight stays on for about 10 secs.
6. then the screen switches off
and it really appears to be powered off.
But if I quickly 'touch' the power button
the TWRP screen briefly appears (with a lock over it) once
and then the green battery screen reappears.

If I unplug then replug in power,
the same things happens: steps 1-6 above.

Tried flashing TWRP 3 times - no change.

Will now try flashing philz.

Philz does exactly the same as CWM - not surprising given that it is CWM based.

So have returned to TWRP, which is at least usable.

Any idea how to file a bug against CWM?
Philz I can do on their forum here.

Well removing the red development purposes text is easy enough if you have S-OFF. Remove Red Text on Splash screen

I'm not sure if the same issue with CWM is applicable to all or most users of Philz on here, like I said before, I haven't noticed any threads popping up discussing the issue, unless they discussed it in Philz thread itself.

I myself haven't noticed the issue you have with TWRP, will look into it more as I get some time, gonna be a hectic week Personally I only use custom recovery when I need it, which isn't that often, not a big "flasher" of ROMs etc, so I'm on stock recovery.

Yes, found the post for Remove Red Text on Splash screen early this morning. Seems to be related to Root, and separate from the TWRP issue.

I have to wonder if the TWRP problems aren't caused by the initial flashing of CWM. Anyway will post the issue on the TWRP forum tomorrow and see what they say.

Seems Philz has had this problem before, it comes from CWM, and fixed it before.

I have to say, this is the last HTC phone I buy - Samsungs are so much friendlier to flashing. Also I greatly dislike the big Tampered sign.

Reason for flashing recovery this time is I wanted root so I could remove garbage from the phone.

I don't flash ROMs much. High learning curve and risky. I do just one flash: from stock to CyangenMod. so much nicer it is worth it. I have to say if I had to choose between my old S3 with CyanogenMod and a stock M8, it would be the S3. If I can't get the garbage off the M8, I will just put it in a drawer till CyM goes stable for it.

The solution! From the Philz M8 thread.
http://forum.xda-developers.com/show...php?p=53464839
An earlier version of Philz: 6.26.6-m8.zip.
The earlier version doesn't have the problem.

Thanks to @donmarkoni
