HTC M8 stuck in bootloop - One (M8) Q&A, Help & Troubleshooting

Hi guys,
Got a phone a need to revive. I received unusable. Mother gave it to my sisters friend and she said it doesnt work. I now see why cause he was trying to mod it.
I managed to once get into TWRP but cant anymore. It was UNLOCKED but now RELOCKED which I possibly made it a little harder for me.
So currently "fastboot getvars" reports back all the info. It's showing version-main 6.13.206.5 and I just want official O2 stock so can use the phone. Ideally sim unlocked but could hassle O2 for that later since it was my mother's contract.
Basically just want to get a working recovery image on and then flash stock. CID is 02__001
Any suggestion to revive this welcomed, please.

So it still have twrp on it ? If yes, boot to twrp recovery then restore the stock backup.

No, I cannot get into it. When I select HBOOT, then select recovery it just shows white screen, ANDROID and then back to the menu. TWRP no longer works. That's what I'm trying to fix or put on a stock recovery image and then stock OS/firmware.

Just wondering if I need to UNLOCK it again and also do I need USB debug on. I cannot boot into OS so unable to set USB debug.
To UNLOCK bootloader can that be done if you can only get into bootloader menu? S-ON is enabled but not 100% that will stop recovering it? That's just for signed rom/firmware and I just need something stock.

You don't need usb debugging on to unlock the bootloader as it is done on fastboot mode (bootloader).
First I suggest you install the O2 firmware only then see whether you can boot to OS (assuming the OS is still stock base)
Second, re unlock bootloader with unlock_code.bin that you can get from htcdev.com, install twrp 3.x and restore the stock backup and relock bootloader and reflash firmware. This will get your device to fully stock.
So far, I don't see any RUU for your device version that you can get for free, only paid site has it.

Relocking the bootloader renders the phone unable to boot into OS by definition, as it expects RUU to be run (but as mentioned, RUU is not available for your CID unless you pay - but it's not needed).
Also, you can't flash TWRP with a locked bootloader, again by definition. The primary limitation of an unlocked bootloader, is that it prohibits flashing unsigned recovery images.
So as suggested, simply unlock the bootloader again (with existing unlock bin code, or get a new one using the HTCDev.com process again). Then flash TWRP and a stock TWRP backup using ckpv5's backup collection (linked in his signature).

ok, well made some progress.
unlocked the bootloader the official way. Very quick which I was surprised.
This then repoened up the recovery menu working.
then used fastboot to install latest twrp
then installed S.Team-JW-7.5.0.zip !!!
The install and everything looked good, no errors and now just not turning on. I think now it's a brick? Does not seem to be coming back to the bootloader menu and certainly does not try to boot.
Wondering if end of the line. Any suggestions? I assume need to get into TWRP and flash stock update from ckpv5.
Must say thanks for replies guys. ckpv5 you done some good work on here.

It's really hard to brick this phone (especially with s-on) just flashing TWRP and flashing ROMs. Probably not a brick.
At what point exactly did it shut down/not reboot? ROM installed with no errors, and when you tried to reboot, it went dark? You aren't specific on this point.
How much charge was on the battery when you were flashing the ROM? Did you leave it a long time flashing the ROM, or rebooting, that simply may have drained the battery to shutdown?
Try leaving the phone on charger for several hours, then hold power+vol up for a minute or so, and see if any change (even if just stuck on HTC logo screen).

Hi there,
Well I expect the bootloader to be separate from the rest so we can get into TWRP and normally get out of this situation?
The ROM install finished, battery was at about 80% and everything looked good and I let it reboot the phone. And then it went dead. Right now the PC keeps beeping as a device has just connected and then again as though it's disconnected. I'm watching the device manager and dont see it listed during the connect but device manager tree refreshes. My S7 edge shows up. It flash an orage dot twice, so appears to be a in loop.
I charged the phoned and no luck with any of the power+ vol +/- keys. No response from any of those? I let the phone sit till flat and no orange light and then charged it today and still nothing. Not sure if it's a bad battery but it was up at 83% showing in the TWRP menu and working plugged or unplugged.
It's become a challenge now to make it work, I havent had to mod phones since my HTC One which got heavily modded and then back to stock. I stopped doing that after modding every phone I had since HTC Desire Android 2.3. So been about 4 years since doing all this again. Never had one that was totally bricked.

You are correct that bootloader (AKA hboot) is a separate partition, isn't touched by TWRP, and in fact is "protected", and can't be modified with s-on. Only an official signed zip (RUU, OTA, zip) can write to hboot when s-on, which is one of the reasons why I say this phone is hard to brick with s-on, just by flashing TWRP and flashing ROMs.

You won't connect to the phone by PC in any way, unless you can get the phone to power on, at least to bootloader.
A few additional suggestions/comments I made to another user (in another thread) who by strange coincidence has a very similar condition (apparent brick after flashing a ROM): https://forum.xda-developers.com/showpost.php?p=73062871&postcount=10
But to be honest, it's not looking too good, since the condition hasn't changed after charging and trying the button combos.

Cheers for that. Not getting much except for the 2 brief flashes of orange light.
Any chance the battery is totally messed and this is the problem?

It's possible. Or it might be something else like motherboard or emmc. It's impossible to say for sure.

[Q] HTC One X Bricked

My issue was caused by trying to flash Mike's AHD ROM. I was able to Unlock the Bootloader via HTCDEV and Flash latest clockwork recovery. I understand the phone will not charge with that recovery, so I've flashed stock back and I was able to borrow an iPhone plug to get the phone to charge.
Issue is now: The phone will boot up and it boots in the setup process. It's when i try to skip through that process the phone flashes "Low Battery" and shuts down. The phone's battery is close to 100%. I have a backup but it yields the exact same result.
My question is: How do I flash back to bone stock? I'm not sure how exactly to determine which RUU I need? I'm in the US and the phone was purchased through Negri Electronics.
HBOOT - 0.32.0000
RADIO - 1.1204.103.14L
If I can ever get back to normal, I feel comfortable flashing Mike's ROM. I just wish his instructions would have mentioned the need to copy over his ROM to the phone before flashing the recovery. Sort of threw a monkey wrench into everything.
Thanks,
Forgot to add this bit:
MIDJ4610000
CID: None
**Update**
I was able to find my RUU just by trying a couple of different ones. The phone is working beautifully now.
I oem locked my bootloader and flashed stock recovery. Then I rebooted the phone back into fastboot and just ran the RUU in windows. Took care of everything!
I do not have a method for those of us who cant pull CIDs... I guess just try different RUU's until you get the right one.

Which RUU worked for you?

HTC One M8 - Stuck at Boot Screen after SkyDragon Flash.

Hello Everyone,
I am having an issue with my M8.
I decided to try out SkyDragon, give it a shot.
I downloaded the ROM, put it on my SDcard. Flashed Philz 6.25 recovery, did NOT make a nandroid backup (I know i'm an idiot),then proceeded to flash the rom via Philz.
I flashed the Rom, and followed all the instructions, I then rebooted the phone. Still stuck at the bootscreen. I read the Q&A and tried to flash the rom multiples times. Still stuck on the boot screen. I have an unlocked bootloader with S-ON.
I just got this phone a few months ago and I am unable to take it out of this state. Could use some help. Thank you.
Is your firmware up to date? Not sure about Skydragon specifically, but long boot times (along with broken WiFi) is often a symptom of outdated firmware.
Let the phone alone for 10 minutes or so, and see if it eventually boots, and isn't actually "stuck" (but rather just takes a REALLY long time).
To flash a different ROM, adb push it to internal storage, or put in on your SD with a USB card reader connected to your computer. Then boot into recovery and flash.

Hello,
I've actually tried flashing another ROM "Android HD Revolution" I believe. The phone shows the HTC Screen along with some red text at the bottoms saying "this build is for developer purposes only....". The phone then stays on the HTC screen for ~3mins then reboots and continues to boot loop.
You just need to flash the new firmware that is found in the sky dragon OP.
Easiest way is to use fastboot. Google fastboot firmware m8. Lots of guides out there. It's only a few commands.
Edit: Should have asked if you are s-off. That will make a difference in your ability to flash new firmware.

Hello Thanks for the reply.
However, I am currently S-ON, I have searched ways to achieve S-OFF but they all require installing a ROM. However, I cannot flash any rom, I will just get the bootloop. If you could advise on a method that would work for my situation, I would be very grateful.

Start with fastboot getvar all command in fastboot/bootloader, put the result here (delete serialno and imei no.) .. then we'll see whether is there any stock ROM available for your device.

You needed to make sure you have the latest GPE software, s-off and supper cid... Also you need to know and have ADB/FASTBOOT installed on your PC.. All which can be found throughout all of the various threads.... Right now you soft bricked your device and needed to return to stock... And stay the process over.

You don't "need" the latest gpe software. The rom runs fine on the latest sense firmware.

Issue Resolved!
Hello Everyone.
The issue is resolved. Through many flashes, wipes and commands. Its done. I was able to flash the rom, let the rom sit for ~20mins, and it finally booted up into Lollipop. I now have no wifi. However, I should be able to follow the FAQ to get S-OFF and fix my wifi!. Thanks team. I really appreciate it.

Bricked my HTC 10, What to do next?

Hey everyone, so I am pretty sure I bricked my HTC10.
To Start off my specs are the HTC 10 Unlocked version
htc_pmewl
CID: BS_US001/BS_US002
MID: 2PS650000
OS: 1.80.617.1
OpenDSP: 18.2.8996.00524_0321
(orignially Stock ROM)
I was trying to reset everything to stock settings before I returned the phone (Unrooting, Locked Bootloader, Stock Recovery, etc) and everything was going fine until after I rewrote the S-OFF flag to S-ON (I'm pretty sure it happened there, maybe when I relocked the bootloader?). Now I don't have a ROM, the CID and MID's are missing on the fastboot (download-mode) page. The Bootloader is relocked, and I have a stock recovery.
I tried going here to get the RUU's and everything to fix what I had done. However the RUU.exe gives me a error 120 Low Battery when I run it (Even though I have a fully charged battery). I tried going to a different PC to run the RUU, but the RUU never runs past the initial install.
I also tried re-unlock the bootloader so I could reinstall TWRP and flash that way. Unlocking went fine, but when I try to flash the twrp img via fastboot I get an error (9 RU_SECURITY_FAIL recovery and bootloader isn't BL_UNLOCKED).
I'm really at my wits end here. I haven't actually done anything this stupid in all of my customizing my M8, S6, Razr or all my tablets so I honestly don't know what to do. If you guys could throw me a lifeline I'd be grateful.
Thanks
Have you tried doing a factory reset using the stock recovery?
See if you can get a system.img to flash manually. If you can get an OS boot you should be able to fix your device.

Using the adb shell command (recovery --wipe_data)? Yeah I've tried that, but I get a device not found error. adb isn't working right now, however I am still able to get fastboot commands, and the phone recognizing them at least. Otherwise, no I haven't what would I need to do?
@tw1tch175 is right. Try to find an untouched system image first and try to flash it in download mode.
Could you in addition tell a bit more about what you did to reset the device to stock instead of flashing a RUU in the first place prior to writing secureflag 3!? And further more what did you do prior to it, did you flash unsigned firmware, or one of the "no red text on boot" aboot provided here!?

Are you making sure you are in download mode for fastboot commands. Also double check your driver in the device manager.

Sure. I originally ran the factory wipe/reset via the ROM (Which was the stock rom). Then after that I booted up into the download mode, tried relocking the bootloader with fastboot oem lock. I also flashed the stock recovery for my model. Once I saw that I had the stock recovery on, the bootloader was locked, and everything else, I tried to do a twrp restore and relock it, but it wasn't working so I said "Screw it" and rewrote the secureflag, rebooted and...yeah everything was gone.
The only thing I did before all of this was when I got the phone unlock the bootloader, SOFF, Custom Recovery, and sideload super SU for root. The only "unofficial" radios/firmware/etc I had was the Verizon Radio on my phone.
Other than that I kept it clean. I'm looking for an image now to try that.

Yes. I just figured that out while searching haha. I did go through and use the UI, but I had no luck. I am looking for an img like you said but I am not having luck so far. Is there one of the Stock guide on my original post?
Ok so for ALL HTC the only proper way to s-on is to use fastboot/download and for oem writesecureflag 3, you should NEVER EVER EVER us echo/dd /hexeditor to go s-on.
For 2016+ phones, you should use sunshine or another tool to go from unlock/relocked to lock, do NOT use anything not designed for the phone in question, or attempt to do it manually. I can only vouch for SunShine's capability to safely change the bootloader status, I can't vouch for any other method or tool. I know SunShine does it right.
See http://forum.xda-developers.com/htc-10/how-to/psa-htc-10-s-off-s-lock-unlock-t3371264 for my PSA on the subject.
If the phone won't flash with a proper RUU, well you need to find someone with a EMMC write tool to rewrite all your firmware, this is probably going to run $100-200.

So as I thought. You indeed flashed - at least parts - of an unofficial firmware. Prior to relocking the bootloader with SunShine, as well as setting S-ON you should've taken care that ALL its stock. A simple factory reset in the ROM settings wasn't enough.
I'd guess that the wrong radio led to a problem when booting with stock recovery of your ROM, relocked bootloader and secureflag set to S-ON.
If I saw it correctly all RUUs for your device are *.exe files. Best would be to extract the ROM.zip from this exe, using 7zip, rename it to 2PS6IMG.zip, place it on an external SDCard (formatted extFAT or FAT32) and reboot to download mode, to give it a shot.
Hope this will help.

Ah gotcha. That makes sense. Wouldn't have been the only thing that slipped my mind. I lost access to my Steam authenticator too. I was able to get the zip from the exe file like you said, after I put that on an SD card and boot to download mode do I just fastboot flash zip?
If there's one thing I remember when using Sunshine to go S-OFF on two different HTC 10's it was that it mentioned something about going S-ON and how something wasn't guaranteed, I forget what exactly, but if I remember correctly I understood it as you shouldn't go back to S-ON because it wasn't guaranteed to work or something like that. Anyone know what I'm talking about?

That is in regards to wiping data, earlier versions of sunshien wiped data on all htc 10 going s-off, thats not the issue here. Issue here is he improperly set the phone lock/s-on. Gotta use sunshine to set it locked, and fastboot to set s-on.
Hey Everyone just wanted to give an update since yesterday evening.
Just wanted to give out some props to @5m4r7ph0n36uru . Following his advice of extracting the Rom.zip from RUU .exe I was able to run it in download mode and loaded up an OS on the phone. So Now I am unbricked! Yay. I had to find out how to do that using process monitor and everything, but it was a success. and I can breathe easy. Thankfully doing that was easier that doing the Database call handler stuff from today at work XD
Thankfully my lesson is learned and I'll flash correctly to full stock next time. Thank you all for your help in the matter.

Hello,
Just to inform that if I try to run RUU.exe from PC when the phone is in bootloader menu, I get battery low error. However, if I "boot to download mode" in the bootloader menu, I can run the RUU.exe from the computer without any error.

European Stock One M8 stuck in HTC logo

I have a european One M8. I turned it off when I got in the plane and after landing it never started back
It gets stuck in the HTC logo.
Some times it moves on and says that "android is updating 165 applications"...and when that finishes it says that Sense Home has crashed and shows the HTC logo again (strangely I can change the volume at that stage ).
I tried to enter Recovery and did a Factory Reset but still nothing. When I select the Recovery option inside that menu I only see an icon of a phone with a red icon, no options to wipe cache etc...
The phone is STOCK, S-ON, no root nothing.
Any suggestions? Can I just reflash the stock rom?

Possibly. What does it say for OS number on the bootloader screen?
Also, please confirm near the top of the bootloader screen, it says LOCKED (versus UNLOCKED or RELOCKED).

Did you find solution/fix pls ?
I seem to have similar problem.
After Factory Reset phone went into White HTC Screen and stopped. I'm only able to access Bootloader and Stock Recovery now. There is no OS.
OS.1.21.401.1
HTC___001
HBOOT 3.19.0.0000
S-ON
LOCKED
Software Status: Official
I tried to Unlock bootloader. I used Hasoon's tool. I confirmed YES to unload bootloader. But after restart Bootloader is still locked.
I tried to flash boot.img and recovery.img but all FAILS.
I can access the phone via ADB but anything flashing always fails. Tried sideload via ADB in Phone's recovery. But always Fails.
I can't access SD via Recovery, says E: mount fail. Tried to re-format the SD but no result
To me it seems like bootloader is corrupt and seems that without proper hardware I won't be able to do anything...
I spent many hours now and about to give up. Please let me know if I missed anything before I will, sadly, have to try professionals.

Hey, thanks for the reply. I haven't managed to do anything neither did I spend a lot of time on this. I was waiting in case someone could help. Such a shame if the phone is bricked. I do not know if it is worth taking to professionals as its value as a used phone is quite low at the moment...

Unfortunately, I don't think your version has an RUU (or from a free source, anyway) that would restore your phone fairly easily (assuming the problem is software, and not hardware).
That being the base (no RUU) you can restore by unlocking the bootloader, installing custom recovery TWRP, and restore a stock TWRP backup (stock ROM).
So it is possible to recover (again, as long as it's not a hardware problem). But it's not a short/simple procedure, if you aren't familiar with these terms and methods.
I fixed it by unlocking the bootloader from HTC's website, installed TWRP and then flashed the LineageOS Rom...

Nice work. It was hard to tell from your post, your level of knowledge. Did you have to learn how to do this, or had prior experience unlocking bootloader, TWRP, etc?
I was on vacation/holiday last week, and not on XDA. So sorry it took so long to get back to you.

Thanks for the help. I have had previous experience installing custom ROMs on HTCs
(HTC Diamond, Wildfire, Desire, Desire HD, Desire S, One S, One X and now the One M8 )
I was just hopping I could get an easy solution without having to go through the whole process

Well, I've pretty much managed to screw up my HTC 10. I'm on the latest 3.16.401.2 WWE, S-ON, with the bootloader relocked and stock recovery. I can access the download mode, the bootloader and the stock recovery, but I can't unlock the bootloader since I can't active the OEM unlock option. The phone doesn't boot, it's stuck in a bootloop at the white HTC logo.
Using the OTA available for WWE gives me the Status 7 fail error. Is there anything else I can do, besides from waiting for the Oreo WWE RUU?
Thanks in advance.

I won't even ask how or why....
But yes you could S-off or wait for an RUU to magically appear.
Those are the two options.

It's pretty complicated, but long story short, I was stupid.
I can't S-Off without being able to boot the phone, so well, I'll probably just wait for a RUU.
HTC 10 boot loop
Hello guys,
my wife yesterday tried to update OTA (our htc 10 are completely stock) to OREO from Nougat 2.41.401.41. Something went wrong and it's stuck in a boot loop. I can get in bootloader and tried to install the ota, which I downloaded, manually from SD card, but after verifying it says "error: partition has unexpected content". Is there a way to get the phone back working even with data loss? Thanks really for the help, the phone has never been modified, I am getting crazy reading the forums but I am a total noob ?
i have seen i need a ruu, possibly zip since I can't boot and activate USB debug. Can someone please share a run.zip link at least equal to 2.41.401.41 (European)? Thank you very much
I have the same issue, HTC 10 in a boot loop after applying the OTA Oreo update. I'm able to get into bootloaders and such, but i need the data thats on the phone... Allready tried taking out the SIM and SD-card. Does anyone know if this can be fixed?
Same problem here!
After Reading what the rest of you lot mentioned here, i have the exact same problems! Installed the update from Nougat to Oreo, and the phone went into bootloader! I was stupid enough to delete most of it through TWRP, and even dumber to RELOCK it so that TWRP is out of the Picture. Download mode appears, but the recovery just brings me back to bootloader. Oh yes, and the OS is missing.
and fastboot / adb wont recognize the HTC Connected to the PC anymore.. Guess this is a total Brick? should i send it back since i have a warranty? Will they be able to fix this?
I too was stupid and relocked it while reverting to stock. At this point I had also flashed the stock recovery and recovered to what turned out to be a non-functional backup. (Stuck in boot-loop)
Thankfully Fastboot did however still work while in download mode, and I was able to unlock it again by flashing the same unlock_token.bin that I have kept since I unlocked it the first time, slapped in twrp again and I was good for another go.
M8 can you help out linking some procedure for a noob like me? Should I use a ruu? I am completely stock
I'm no expert in this my self just FYI, but installing a RUU is usually a straight forward process.
You need to download a ruu for your particular CID (Depens on where the phone was sold and what -if any- carrier the phone is locked to.)
I have an european unlocked one so the RUU I used was this: https://androidfilehost.com/?fid=817550096634797504
You can find more in this thread: https://forum.xda-developers.com/htc-10/how-to/stock-stock-collection-recovery-ruu-ota-t3359297
Download the ruu (just short of 2GB in size) , rename it to 2PS6IMG.zip and put it in the root of an SD-card and insert it into the phone.
Reboot it into download mode by holding power+volume down until the grey HTC logo appears.
It should now detect the zip file in the sd-card and ask you to install it. Press volume up to confirm.
This will re-install everything (System image, recovery, firmware etc) all existing data gets destroyed.
Worked like a charm for me, and was able to do a Oreo OTA right away after the first boot.
Thanks a lot for your help, I'll give you a feedback asap.

Take the OTA. Did you flash a Oreo ROM while on nougat firmware? If so updating to Oreo will fix the problem.
Thanks Alot

I have an Indian HTC 10 (SD 820) full stock, no modifications. One day the phone froze and i restarted it and from that day it hasn't booted up. The htc logo shows up while it vibrates, then again the same screen. Stuck in a bootloop. When i get to bootloader and boot to recovery, the grey htc logo comes for 1 second and then it goes back to the original boot animation and it loops again until the phone dies. Whenever i plug my phone to the charger, it immediately gets stuck into the boot loop. Please help me !! Any fix please !

Hold the power button and the volume down button to reboot to download mode. From there you can flash an RUU.zip to fix it.
What is needed to direct you to the proper RUU.zip to download and flash is for you to boot to download mode and post here what it says next to "OS"
