[Q] HTC One S-Off, and Unlocked boot looping

Hello,
I have accidentally flashed a GSM rom on my CDMA device(I know stupid of me), and I also did not take a nandroid(very stupid of me). I have access to Recovery, Bootloader, Fastboot, and Adb Sideload. I have tried Sideloading a rom, but I get "This package is for "m7wlv,m7vzw" devices; this is a "m7""

Thanks,
Have a wonder night!

I would grab one of Hawk's stock Roms and flash it in philz's recovery.
But it sounds like your CID or something is screwed up.

I ended up fixing it with an RUU I found, however, when I try to install Viper 6.1.0 it successfully installs, but just boot loops. It will get to the htc logo, and just reboot.

I think you're using the wrong recovery, make sure that you've downloaded the the m7vzw version. I made this mistake the first time I went to download CWM.

Do you mind giving the steps on how you fixed this problem? I am getting the same error you had in your OP and can't seem to get anything to work.
Thanks

[Q] Soft bricked, can't boot after flashing any Rom

Hi everyone! My problem is that if I flash any rom (I've tried ARHD, Viper), the phone gets stuck at the boot screen. I've left it in that state for almost an hour and it hasn't progressed further. Restoring my nandroid backups also yields the same result. My fastboot getvar all:

The phone is currently unlocked, s-off. I tried flashing with both, philz and twrp, none work. Also, these roms worked before on the same phone with the same recovery so I really have no idea of what went wrong. The firmware on the phone is 1.56.720.6 (Asia-India). I have tried clearing the cache partition multiple times, but it doesn't help.

@EddyOS, @nkk71 please see this. I think there's something wrong with my /data partition..

Did you recently do the GPE conversion?

May be you should try to flash the stock rom and stock recovery then flash the ruu.

This, the partitions get altered so you can't just simply flash back

According to the OP's getvar output they've NOT done the GPe conversion as the HBOOT version included in the RUU is 3.18.0.0000 and the OP is still on 3.16.0.0000
OP, I'd follow my guide linked in my signature and you should be good to go

I hadn't touched the firmware, so there shouldn't be any problem related to that. Anyways, a rom and recovery do Not affect an RUU flash.

I flashed the international fw zip, and ARHD, (I had checked the hash of the file) and it still didn't work. Also, when I would reboot, some random artefacts would appear during the boot animation (different each time, sometimes wouldn't appear), such as there would be a random flash of purple across the screen or the boot animation would leave a trail behind it (like the effect you get web you would drag a stuck window in win98) etc. sometimes TWRP would act extremely sluggish while sometimes it would be fast and snappy. Quite a few times, while flashing any rom, the screen would go black and reboot to TWRP at random (even after disabling the display timeout). I tried formatting all the partitions on the internal storage. Still gave me problems. I tried to repair file system of each partition in TWRP. The data partition could never get repaired. All of these random problems lead me to believe that this was 99% the fault of the phone/hardware. Luckily I was within the 14 day replacement period and so I went out today after flashing the faux locked/s-on bootloader (I know I should not mess with firmware unless required, and I hadn't till now but I didn't care anymore since I was getting it replaced anyway. I also had 2 dead pixels and a scratch on my camera glass. Now I just have to sit back and wait for a new phone

We've seen this issue on Viper a few times and it usually happened after someone installed e.g. a VZW recovery to the GSM phone or vice versa.
A wrong recovery would flash stuff into the wrong partitions.
A RUU for your device, really just any, should fix it. You should run a RUU and then factory reset right afterwards from bootloader BEFORE flashing another custom recovery.
There is a cingular (AT&T) RUU out right now from HTC here: http://dl3.htc.com/application/RUU_...G_20.31A.4145.02L_release_368350_signed_2.exe which you could try - it is a GSM RUU. We don't really have WWE 401 RUU yet.
Just make sure you don't grab a SPRINT or Verizon RUU if you find any!!!!!!

Too late for trying a fix , I just want to know what caused it, and I'm 1000% sure I had the right recovery, because as I said, I flashed many other roms in the past with the same recovery, and the problem came after I tried ARHD. And this is the gsm phone.

Yeah well no idea then. Just know I've seen this happen from wrong recoveries. Also not the time to dig into it any further if you've gotten that resolved already I'll leave it as is. Thanks for asking me though. Just keep in mind I've been out of XDA since months and am only slowly reading my way back in so I'm sure there are way more knowledgeable guys around regarding firmware, softbricks and the like.

In such a big mess! I have the same problem as the OP - same to the last dot. I am on India version of device, and was just trying to update firmware to 4.4.3 and in that quest i flashed firmware from here http://forum.xda-developers.com/showpost.php?p=54899772&postcount=1392.
Post that camera and wi-fi stopped working - so I thought may be I screwed up with boot.img and reflashing Viper/ADHD would solve it. While on my way to install Viper I cleaned/wiped data in recovery and hit reboot accidentally which got the phone to stuck in bootloop. I pushed in back in recovery however, since then I have not been able to install either Viper or ADHD. I even tried doing a nandroid back-up from here: http://forum.xda-developers.com/showpost.php?p=54940131&postcount=1419, however nothing brings me past the splash screen.
Off-late (few hours) I am not been able to do a back-up (nandroid) as my recovery throws cant mount sdcard or sdcard1 both. Please help!

Yes, I did. Using HTCDev.
At the moment, I would be just happy with someway of going back to the clean slate. Is there a way I could go back to original/stock using ADB/Fastboot as recovery also doesnt seem to work.
Thanks

M8 stuck in bootloop(?)

Hey guys,
First off, any help here would be more than appreciated as I am at my wits' end.
So, i shall try and inform you guys as much as I can and hope it suffices. My M8 seems to be stuck in a bootloop. I can get to the bootloader (hboot & fastboot) and that's about it. I tried to flash a new recovery and kernel through fastboot but that doesn't seem to help either. My phone has been unlocked a long time ago but never had any problems until this suddenly happened.
Here is my oem info:
(bootloader) version: 0.5

PS- It is also interesting to note that when my phone is stuck on the white HTC screen, i can hear message notifications and such implying that the phone is still running ( I even mirrored my phone to the pc using USB and I can see my home screen on my laptop but just the HTC screen on the phone.
Thanks a ton in advance

Were you trying to flash anything (such as a custom ROM) to make this happen? If not, why would changing the recovery make a difference? If yes, what did you flash?
Phone was on stock or custom ROM when this started to happen?
Do you have a nandroid backup you can restore?
Also, newer versions of TWRP won't work with your (ancient) hboot, so depending on what TWRP build you flashed, you can just be adding to the problem.

No, I wasn't trying to flash anything which is what baffles me more. My phone just froze all of a sudden and I had to use Power+Volume Up to reboot and it hasn't been starting up ever since.
I'm current;y running a custom ROM (skydragon if I remember well).
The last significant change I remember making was giving the "Clean Master" app accessibility permissions through the settings. Idk why it didn't just ask me to do it through SuperUser there.

As I asked before:
Do you have a nandroid backup you can restore?
If so, try to restore that backup.
Otherwise, try to re-flash the custom ROM.
What version TWRP are you currently on?

M8 stuck whilst loading recovery mode..

So i accidentally wiped the phone including the internal storage and the OS instead of factory resetting (wasn't paying attention) and tried to re install the android marshmallow OS onto the phone which didn't work..
i managed to flash the twrp by following another forum where someone had the same problem, using the adb process to flash the bootloader etc but now i can't access the recovery at all, it just says entering recovery and remains idle until i get bored of waiting and power off.
Can anyone help me?
i can provide whatever information is necessary for you to help, just need my phone revitalised as i desperately need it for my new job that i should hopefully be starting at the end of the week.
thanks in advance!

I have quite the same problem (and i have One M8). Can't enter TWRP recovery, bootloop - just shows an endless loading, i can start the phone without that by pushing pwr button/VOL+/VOL- at the same time (fastboot mode - ok). I want to get the stock back, but it's impossible without entering TWRP. Can someone help me please? It seems that i do not understand this thing anymore.

Fastboot erase cache, then flash TWRP again in fastboot. Try TWRP 2.8.1.0, which is an older version (more compatible with your old firmware). Then see if you can boot into recovery.
Or flash signed firmware, to update firmware (yours is ancient) then flash TWRP 2.8.7 and restore a newer stock backup (corresponding to the firmware flashed).

Thanks a lot. I've tried the first solution and at least TWRP is now working. I've tried the same thing, but it seems, that it was a wrong version of TWRP

Many apologies, turns out i misread the model and its actually the M7 i have. But im glad that this post is helping others with my original problem and thanks to other members who contributed to helping!

Old HTC one M8 recovery twrp not working

All,
I'm really stuck here. I have an old HTC one M8 that I used to have running Omnirom 4.something. This was a long time ago when I didn't know much about flashing phones etc and I broke it at the time by trying to install a new version android ROM to it without S-off and updating the firmware (Didn't know about firmware at the time). Broken . I've since gone on and have a perfectly working rooted modern M9. But I pulled the old M8 to try to recover it.
It's at a point where it won't boot into recovery.
It's currently S-ON. I have flashed multiple versions of TWRP to the device to no avail. When I choose "reboot into recovery" from the bootloader screen it comes up with "entering recovery" in red over the HTC logo and just sits there. I've tried versions from 2.7.0.2 to 3.0.2.0 and no luck. Below is the output of my getvar.
I've tried flashing the recovery twice and using "flashboot erase cache" as well. (tho I might not be doing it in the right order?)
I get the feeling my hboot is really old and I'm probably doing something obviously wrong. But I mostly just want to get it where recovery mode works, Get an old ROM on it. S-off it and then bring it up to whatever I want.
Any suggestions on how I can get this back to a working recovery mode? I assume it just requires getting a working set of the right compatible SW to line up to get it working. But I can't for the life of me figure out what that combo is. Any help would be much appreciated.

Your device is M7 not M8.
Flashing TWRP for M8 on it definitely won't work.

Bwahahahaha Oh god, I've been bashing at that for a whole day and I never noticed that line in the getvar, I really had it stuck in my head that this was an M8. I am super embarrassed. Thanks so much for that. I should probably find this easier now. I'll see myself out.
