My stock M9 is stuck in bootloop! Can't boot to recovery! Help please!

Hello guys!
First and foremost, I'm new to the forum as well as an Android noob (switched from Iphone 5 half a year ago). I have never rooted my phone nor have I flashed a custom ROM before. I have a 32 GB HTC One M9 from Verizon on stock Lollipop Android, and it has been working perfectly until this morning. I woke up to my M9 stuck in a bootloop. It would boot to the HTC logo, stay there for about 10 sec, then go black and constantly restart again (even as I type this). I can access the bootloader, but it seems none of the options work for me! I can't boot to recovery mode or even power off my phone. It just constantly boots again by itself. I've emailed HTC support and hope to hear from them soon, but I figured why not ask a respected forum as well. I've read up on similar issues from other people, but it seems none of their solutions work for me as I cannot access recovery or even do a hard reset! Any help is appreciated! I want to be able to use my phone ASAP!

My bootloader says S-ON. I have no idea what it means by the way, sorry I'm new to this.

No worries my friend. Htc will be your best help since its not been rooted.
Best of luck.

An update for all those who might have the same problem. I've successfully contacted HTC live chat support and have found out that my device is defective. I have no idea what the cause might be, or if there is even a solution to fix it yourself. I will be receiving a replacement device in two days thanks to HTC's wonderful customer support and exchange program. Thanks to all who provided input!

Then when you get it back. S-OFF and root the dang thing!

Make sure you check the replacement phone really well. HTC is likes to send out lemons as replacements. I went through 8 rezounds in 9 months.

HTC One M9 Sprint, stuck in boot loop
I just checked the Dead NAND post in the FAQ... matches my issue too.
Q17: My phone is completely stock and started bootlooping during normal usage. Now I can only enter the Bootloader since I face booting errors as soon as I try to enter the Download Mode or the Stock Recovery. How can I fix this problem?
A: This seems to be another symptom of the NAND death (c.f. the black download mode error screen in Q8). So far, it's not fixable without HTC's help. In other words: You need to send your phone to HTC's repair service if you want to keep it.

Recover on from bootloop on H815 EU

Hi guys,
Yesterday I got sweaty hand palms.
My EU 815 G4 is unlocked, the official way, and I had rooted it.
Then I tried to install xposed from twrp and I did something wrong, and ended up in bootloop...
I have just updated to v20b before, and forgot to connect the phone to the PC, and allow the PC debug access before installing xposed, so i could see the phone in ADB mode, but couldn't access it.
Of course I hadn't made a backup before this - I like to cry
Just as a desperate try, when everything else had failed, i thought about using the new tool provided by shakeyabooti LG UP to flash the factory KDZ all over
I put the phone in SW. update mode by:
1. Turning off the phone
2. connecting USB cable to the PC
3. Press and hold vol. up while connecting the USB cable to the phone
Then i downloaded the v20b KDZ file, provided by Autoprime (since this was what i where allready running)
Opened LG UP, loaded the H81520B_00.kdz, marked REFURBISH
Lastly i pressed "Start" and waited for about 15-20 minutes and "TADAAAA"
The phone where up and running again... only things lost where root and TWRP
- Sharing since I'm properly not the only one ending up in this kind of mess :laugh:

Just tried it no luck :/
So just to confirm...unlocking bootloader official way does void warranty and we can not send it in for repairs?

Indeed. Maybe you'll find a cool employee at your vendor who will still do it, but your warranty is definately void and they don't need to do anything. Depends on how acommodating the employee is. If you're stuck in a bootloop @rakinisbat just follow the steps in this thread.
And please keep in mind that there's a way to get out of bootloops 99% of the time (in fact 100% if it's a software related problem), you just have to do a good search on xda. Furthermore there's an uninstaller app for xposed in the official rovo89 thread, which you can flash via recovery and it which undos the xposed installation and your phone will boot fine (if you can access TWRP - just flash it). If you have further questions you can PM me, always happy to help

Thanks Mate, I guess ill have to try my luck with LG,
I have that batch of H815 with the faulty motherboard, unfortunately I'm in that 1% *Sigh* :crying:
Tried literally everything i could with the software, pretty much confirmed it is the motherboard.
It looks like the KDZ is flashing properly, as LGUP shows whichever kdz i put on, but the actual hardware is not capable of booting into the OS.

Oh yeah that really sounds like a hardware problem. Damn it LG! But is your bootloader still locked? You might have a chance to get a new one if it is And if it's a hardware prob you still have your warranty, haven't you?

Nope, my bootloader is unlocked, im a flash-a-holic, longest i have lasted without rooting or unlocking a bootloader is about 2 weeks. I would have never imagined such a massive hardware issue with a flagship phone. I'll probably get a nexus 6P atleast it has better support than a LG. I'm in Australia, I imported this phone when it was released, so i have to send this phone overseas if i want it repaired, which they will most likely deny.
Sooooo over LG now! There are like hundreds if not thousands that are effected they are not even acknowledging it or providing a viable solution.

Nexus 5x stuck at google screen [Potentially Hard-bricked]

*** The issue is resolved!!! Thanks to xda, the solution is provided in the link in the comments.***
Couple of days ago I got this OTA notification that Android 7.1 preview is available for update. As my phone is rooted I started the manual update procedure. After the flashing was finished, I restarted the phone and then I saw it was stuck at the Google screen. Just stuck, no response. Seemed unusual to me.
Let me tell you that I have been modding my Nexus 5 for about two years. I am familiar with most of the tweaks that can be done to a Nexus device. Nexus 5 served me amazingly. I bought Nexus 5x 3 months ago.
So, after it was stuck I restarted. Still stuck. I will tell you step by step what I did then:
1. Flashed the OS 7.1 again (I dunno why, the flash.all script doesn't work for me, so I always do that manually) - result is the same.
2. Last October update (NBD90W) was available in the folder so I flashed that - same result.
3. I downloaded the previous one (NRD90S) and flashed that - same result.
4. I locked the phone and unlocked again to erase everything (not sure if that's a good idea), then flashed the OS again - same result.
5. Then I tried LGUP and the tot files to give it the factory version. LGUP detects the phone, started installing. When the installation is finished and the phone restarted - same result.
6. Now that I gave it the factory version the phone got locked!
7. I searched google for hours but couldn't find a way to unlock it as the OS is not booting and I cannot turn USB debugging on!
8. Then I tried the default recovery mode (Android recovery, from the recovery screen Power + volume up) as it doesn't require unlocking the device. Wiped the cache and restarted - same result.
9. My phone is detected by the pc and ADB. So, I wiped everything and tried ADB sideload and get this error E: footer is wrong
10. I tried Nexus root toolkit. It detects the phone in fastboot mode, then restarts it and then it again is stuck on the Google screen.
I am extremely depressed!
I am from Bangladesh and there is no authorized LG servicing center here. So, I can't ask for their help.
All that I did over the past two years was the awesome threads of xdadevelopers. So, a big thumbs up for you guys . :good:
I learnt from the web that phone can be hard bricked if a wrong bootloader is flashed. That's impossible for me as I always remove the factory image extracted files after flashing is done from the ADB>platform-tools folder.
Now, is the phone hard-bricked? If it is, what to do with it? Will replacing the motherboard get my phone back? Any kind of suggestion will be very much appreciated.

Bummer. This sounds a lot like what I just posted here: http://forum.xda-developers.com/nexus-5x/help/req-help-bootloop-7-1-1-beta-ota-enter-t3486957

Please say something about replacing the motherboard. It's very very pricey, so I want to be sure -_-

sounds like its hardware problem, contact seller to replace it. if not going to happen, then buy a new phone from a company that does have a dealer in your country to warrant. aside of camera, the specs of other phones at this price range are better

That thought is also roaming around my head, still Nexus is Nexus!

What's the price going for the 5X over there? It's as low as $280 here in the US which is easy better then it's original.

Try the tutorial here. It's little bit different from the original thread ,
as @bardhi92 said, THE MAIN DIFFERENCE HERE IS THAT AFTER I FLASHED THE .TOT FILE, I BOOTED MY PHONE INTO BOOTLOADER AND DID AN ADB SIDELOAD OF THIS OTA.ZIP
Well, for my case, eventually I successfully bring my N5X alive. The tricky part is to enter Android System Recovery (hold Power + Volume Up) after flashing TOT.

A warranty is a warranty, it doesn't matter what country you're in or where the repair place is. People in Canada send stuff to the USA for warranty issues all the time. I'd get on the phone with LG until I heard what I wanted, but I'm a stubborn old goat lol.

[SOLVED] Can't get download mode working

Okay, I'm giving up, I need someone to help me.
I was given my neighbours HTC One M9. It was working just fine. After he gave it to me, first thing I did was a factory reset because he didn't delete anything.
After that, the problems began. When I boot up the phone, even directly after resetting and even before the setup, I get an error "Google App stopped working". And after that, all couple of seconds another "com.google.process.gapps stopped working".
I tried several of the fixes out there on the web, but it didn't go away. I did another factory reset, and again even when I setup the phone I get those errors.
There is still Android 6.0 on the phone, so I wanted to update to 7.1
During install, I got the red triangle screen, on both attemps. Well, f*ck.
So, I went on to install a new OS. Never did this before, so I though this is a good chance to learn some more about Android.
It just got even more strange. When I'm in the bootloader, I saw
***Software status: Modified***
S-ON
LOCKED
***Security Warning***
Especially the modified software was very strange, since my neighbour has neither a clue nor any interested of fiddling with phones.
When I tried to go into Download Mode, it said "failed to boot into download mode".
Recovery mode worked just fine.
Therefore, I couldn't do anything to install a new OS.
Next I bought the Sunshine App and S-OFFd my phone, which worked just fine.
Now I'm S-OFF, unlocked and the Security Warning has gone. The software is apparently still modified.
But when I go into download mode, I get the black screen with the silver logo and red text for a while, then the phone proceeds to boot normally.
What the f*uck? I'm just out of idead what to do now. Please don't let it be a dead nand... it's such a nice phone, and apart from the google app errors, it works perfectly. I used it for some surfing around today and it works really well. I can't imagine it being broken.
Thanks for your help!

What variant do you have? Firmware version?

Firmware is 3.35.166.12
I don't know exactly about the variant, this is what the IMEI checker says:
SKU , VF , German , CHE , HTC , CH , Swisscom , Bootloader Lock , Dark Gunmetal/Dark Gunmetal , w/o SIM Lock , HIMA#UHL-D1
I have a bug report of the gapps-Error. Would that be helpful?

I have some bad news for you:
According to everything that you describe in the opening post it's the dead nand issue. There's nothing you can do. And if you send the phone to HTC they will change the motherboard which means that you have to buy sunshine, again, after they send the phone back to you.

@Flippy498 Is the "failed to boot into download mode"? error a sign of dead nand? This happened to me before. I flashed hosd.img via bootloader to fix this. Still using my M9.

It's the combination of several things that make me think it's a dead nand:
The security warning indicates that there is no OS installed. If that happened without manually deleting the OS via a custom recovery like TWRP then chances are high that the nand died.
The software status is modified although the phone is locked and S-ON. The only other explanation for this combination would be that the owner failed while using one of the 100% stock guides that convert S-OFF back to S-ON, Unlocked back to Locked and modified back to original. However, the dead nand issue is quite common during the recent months and the guides are hidden somewhere in the Genereal section (in other words: not located on the first page). Therefore, I think that chances are higher that it's the dead nand issue.
Last but not least: The black download mode error screen in combination with the other two symptoms.
Did you report about your tries to revive your phone somewhere here on xda? Do you have a link? What kind of symptoms did you face aside from the black error screen? Has your phone been S-ON or S-OFF?
If you really faced a dead nand issue and could repair your phone by your own that would be a game-changing and I could finally overhaul the FAQ of the ReadMe thread. However, discussions like the one that starts with this post make me think that you might have faced a different problem with your download mode since it really looks like the dead nand isn't fixable without changing the hardware.

I didn't have to revive it, except that Google-error it works beautifully. That' broken download mode the only symptom I have. The phone is (meanwhile after Sunshine) S-OFF

Well, there are two things that leave me hoping it's not a dead nand.
• Apart from that com.google.process.gapps-error, it works like a charm. No crashes, no sudden reboots. I really can't imagine a broken part of a motherboard making no trouble, wouldn't that render the part
useless? And is that Google-App Error really relatable?
• After letting the Sunshine App do its job, I don't get an error message in the download mode (well, it just boots normally after a while), the security warning has gone as well. Only the modified software is
suspicious.

I've heard of that as well. I didn't really find any tutorial on that and I'm a bit afraid to experiment with that. Do you mind sharing how you achieved that?

Instructions are linked in the FAQ of the ReadMe thread. They're the solution for the blue download mode issue.
The thing is that the download mode can't just break without either you actively manipulating it or the hardware of the phone dying. The same applies to that security warning. Either you manually delete the OS or the hardware fails and the phone isn't able to read the installed OS correctly, anymore. Therefore, I wouldn't put my hopes too high if I were you. Of course I could be wrong but I've read a lot of reports of dead nand phones since last year's summer and my feeling tells me that this is another one.
As a sidenote: You're the first user that tried to S-OFF/successfully S-OFFed his phone after such errors occurred since sunshine can't unlock the bootloader on firmware 4.x and hasn't been able to do so on older firmware versions when the issue appeared the first time. Therefore, I don't know which influence sunshine has on the whole situation.

Yes, I know. Maybe I just don't want to accept that fact to keep my motivation to try to save the phone...
So what my optimism suspects is that somewhere deep in the firmware there is something corrupted. That leaves the System modified and the Google app confused.
After all, recovery mode works just fine. If you check what other people experience with a dead nand, it's got to do with sudden reboots, bootloops, failed download AND recovery modes et cetera.
As a sidenote: You're the first user that tried to S-OFF/successfully S-OFFed his phone after such errors occurred since sunshine can't unlock the bootloader on firmware 4.x and hasn't been able to do so on older firmware versions when the issue appeared the first time. Therefore, I don't know which influence sunshine has on the whole situation.

I've heard of that as well. I didn't really find any tutorial on that and I'm a bit afraid to experiment with that. Do you mind sharing how you achieved that?

You can try this...
Get the firmware.zip matching your current firmware @Flippy498 's thread here. Links are in the spreadsheet in post #2. Extract the hosd.img from the zip and flash in bootloader mode .
Code:
fastboot flash hosd hosd.img
then try to reboot to download mode. If it does not work, try other firmware.zip but should be in the same build number at least X.XX.

SAME HERE PROBLEM PLEASE HELP
I HAVE HTC ONE M9 OPJA100 JUST GO ON LOCKED SCREEN WHEN REBOOT TO BOOTLOADER ITS RESTART AGAIN EVEN NOT GO DOWNLOAD MODE OR RECOVERY MODE.

THANK YOU!!!!
It finally works!
Edit: I installed resurrection Remix. Working perfectly, I really don't think there is anything dead in that phone. It's great, thank you for your help!

Just for the record, that's not my thread. It's owned by Sneakyghost.
@sechsgangchakter: I'm glad to hear that your phone is working, again.

Hello, I am having a very similar issue. I am looking for the hosd.img file for Verizon. I dont see it at https://docs.google.com/spreadsheets/d/1ZaiJ3F_f76sVa4daU5H62OYi5Bj23LEBBv4xDTQ8y-M/pubhtml. Please help. Thanks

You won't find any CDMA files in that spreadsheet because the xda thread that sheet belongs to only supports GSM devices and clearly states that it'll never support CDMA.

So no one knows of one available for Verizon m9? What would happen if I used a GSM one?

You would probably damage your phone unrecoverably. GSM and CDMA are not compatible with each other due to the different partition layouts.
However, why don't you extract the needed file from a RUU that matches your current firmware version? That's how those firmware packs in the linked thread got made, as well. There's a thread with a RUU extraction tool linked in the RUU section of the ReadMe thread.

Good idea, ill give that a try. Thanks

Modified, Locked, S-on, Security warning. Bricked?

So it seems I'm in a very similar situation to people in other posts, and it's looking like my phone could be broken beyond repair.
UK, 02, stuck in a boot loop, Bootloader shows: Modified, S-On, Locked, Security Warning. I cant get into download mode (Download Mode failed to launch) but I can get into recovery mode (I get the red triangle with exclamation mark, Power+Vol Up gets me in). However, from what I read here in most other posts S-On + Locked + Modified means I wont be able to do anything. I have not flashed anything before I encountered this problem, merely let my battery run flat.
Is there anything I can do? I almost gave up, but this post here
HTML:
https://forum.xda-developers.com/one-m9/help/m9-locked-s-bootloader-download-mode-t3547560
gives me hope, as they seem in a similar situation with the exception of being able to get into download mode. Gives me hope I might be able to get into that and at least find out what firmware version I'm running.
Is there anything I can do or should I give up now and save my energy for sending HTC an angry email since this seems to be quite a common fault that's left quite a few people with bricks through (seemingly) no fault of their own?

Try "fastboot oem rebootRUU", if this isn't working you have a dead nand.

Strictly speaking, it's not an HTC specific problem. All phones with the Snapdragon 810 sooner or later suffer from similar issues. The heat of the processor kills the rest of the phones' hardware.

That command only works if the phone is booted to download mode which isn't possible according to the OP.

Ah! Thanks for that. I was scratching my head wondering how to get my pc to recognise my phone!
Dead NAND it is then?

Ah don't mention it. Thank you both for your quick replies. Last question (big long shot) is there any hope of recovering any of the files on there? I don't mind long projects and I'm quite handy with a soldering iron. Prise it open, try to locate something resembling a flash drive, try to remove that without further damage and find a relevant adaptor? I'm assuming even if i were to attempt this I'd be in for a lot of headaches and probably wasted time, but figured I'd try to explore all avenues.
Obvious even if there were ways to do this, the NAND problem is probably going further hinder any remote chances of success.
