HTC One M8 has no OS (Operating System)!! - One (M8) Q&A, Help & Troubleshooting

I just rooted my HTC One M8 and was messing around with roms and when I tapped one my phone shut off and won't fully turn on. It just stayed at the loading screen. I went into fastboot and tried restoring to factory settings and all that and nothing worked. After awhile I relized the phone had no OS
Anyone have any ideas?
Help is much appreciated!

I know!!!
Erase fastboot cache on fastboot mode and flash custom roms on cwm recovery. I do it and working my htc one m8 eye. I think it will be working on your device. ?

i assume you have a custom recovery ( TWRP )
boot to recovery connect your device with PC via USB it will show the storage transfer a custom rom in to your device ( sd card is recommended ) then tap the wipe button in recovery main menu check cash,dalvic,system and data then sweep to confirm
back to main menu , tap install choose your rom sweep to confirm and reboot it should work

try with another rom this log shows that the updater binary wrong or maybe missing
or maybe you have a wrong zip
are you sure this zip is a rom ?
may be you confused between rom and stock backup
can you post all the log

You flashed the new ROM clean, right? With a full wipe? (data~dalvik~cache)
After you get that error select reboot, and in that menu select to reboot to recovery. Then flash the ROM.zip again without wiping.
When done, reboot to system.
After that you should be running your new ROM.

Not enough info.
Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
What version TWRP?
Did you try more than one ROM? What ROMs did you try?
Did you do a default wipe in TWRP, before flashing?

[Q] Rom Manager - Failed to Seek

Anytime I try to do anything through Rom Manager (flash a ROM, nandroid backup, etc.) upon rebooting into recovery, I get a white triangle with an yellow exclamation point. After pressing the power button, the following text is revealed along with the Clockwork Recovery Menu.
Finding update package...
Opening update package...
Verifying update package...
E:failed to seek in /cache/update.zip (Invalid argument)
E:signature verification failed
Installation aborted.
If I select advanced->Reboot Recovery after receiving the error, the device reboots. After this second reboot, the process continues as it should have after the first reboot. I've tried downgrading the version of my Clockwork Recovery, but it seems to have no effect.
Any ideas?
...
I believe the standard array of initial questions would be:
1) Did you flash S-OFF?
2) Is your card FAT32 formatted
3) Try redownloading the file using a different browser (to ensure a cache doesn't deliver the same update.zip without trying)

This failure isn't specific to any one file. Besides, I don't think it's a corruption of the file since it works when I select "reboot recovery" from the first failed attempt. In fact, this even happens when choosing "Backup ROM" from ROM Manager.
On a side note, I've tried wiping cache in ROM Manager as well.
Toggle Signature Verification and/or is d/l corrupt?
In CWM, have you tried toggling the on or off setting for the signature verification, as well as the other toggle?
Also, I read some superb advice here:http://http://forum.xda-developers.com/showthread.php?t=765930
check out the advice in post # 285 and see if that fixes you up.
Everyone seems to think my downloads are corrupt. That is definitely not the problem. If they were corrupt, they wouldn't function after the first reboot. They would continue to fail. Let me try explain my problem another way...
Here's my device setup...
Radio - 2.15.00.07.28
Kernel - King's BFS #4
ROM - SR Vanilla RC 2
CWM Version - 2.5.0.5
ROM Manager Version - 2.0.2.6
Here's a process I'm following...
1. Open ROM Manager
2. Clear Download Cache (Just to be sure!)
3. Select Backup Current ROM which causes reboot into recovery.
4. Receive the error which I outlined in my first post. *NOTE* I have not downloaded nor chosen to flash ANY update.zip files. *NOTE*
5. Open the advanced menu in CMW and choose "Reboot recovery" which causes the phone to reboot into recovery.
6. The backup progresses like it should have after the first reboot.
Again, the process above does not involve the use of any downloaded update.zip files. No ROMS, no Kernels, etc.
Does ROM Manager create it's own update.zip file stored in /cache to execute whatever function it needs to after reboot? It appears that might be the case.
I've attempted to reinstall ROM Manager and downgrade to an early version of CWM in ROM Manager. Neither seem to have helped.
I had the same problem trying to flash the latest leedroid
I entered recovery, de-selected signature verification and then flashed the rom through recovery mode.
Flashed normally and up to now it looks like it worked (waiting for first boot)
Hope this helped
Both signature verification and script asserts are toggled off. This is why the update.zip will flash after the second reboot into recovery and manually.
In recovery, is cache, data, or system mounted? If so, can you unmount any/ all, and reboot?

I just started having this problem today, at least i noticed it today. It acts as if the signature verification is enabled the first try and disabled the second time. I can't find ANY way to fix this but reboot recovery and it works... If anyone finds a solution, please post.
*edit* I also noticed the "Fix Permissions" utility doesn't work in ROM Manager. Dont know if this is related or not.

Did you change anything today? I found someone in the SR ROM thread today that started having the same problem.
No, only an app and removed it. I dont know how long it has been broke since I haven't used it since SR 3.0rc1.. got tired of the reminder for rc3 and it wouldn't automagically run the install.zip.
Interesting.... Please post as this shakes out.

I have this same issue, I think it's an issue with Rom Manager. No matter what I try to do from there (Reboot to Recovery, make backup, flash zip, etc.) I get that string of messages.
If I download a file from ROM manager to be flashed, I have to move the file to the root of the sd card before booting to recovery for it to flash correctly. I have just gotten used to doing it this way.

If you look in the OP for the SR ROMS, you'll see that a known issue. He includes a fix_permissions binary instead.
I've reached out to the developer. Hopefully we will hear from him soon.
Can you guys try clearing your download cache, and then reflashing recovery?

Cache wipe have been tried, see post #3.
I have some info that may be valuable:
This evening I rooted my Desire (SLCD) using Unrevoked 3.14 and recovery-clockwork-2.5.0.7-bravo.img I realize this is the incredible forum but hold on.. hear me out
I observed the _exact_ same behavior:
- Yellow eclamation + second reboot to recovery would run backup, also happened when selecting "Reboot Into recovery" in RomManager (RM)
- Tried DL cache wipe in RomManager,
- Tried reflash of recovery
This fixed it for me:
- Re-root via Unrevoked 3.14 using recovery-clockwork-2.5.0.1-bravo-slcd.img
- Re-flash CM (this may be optional, I don't know)
- Boot ROM and start RM just to have it tell me I need to install recovery (obviosly didn't detect my 2.5.0.1-bravo-slcd)
- Allow RM to flash 2.5.0.7-bravo via download
- Now "Backup ROM" and "Reboot to recovery" works as intended
- RM reports 2.5.0.7-bravo installed, recovery booted (via RM) is 2.5.0.7-bravo BUT recovery booted using HBOOT (back+power on Desire) is 2.5.0.1-bravo-slcd (!)
Note: Incredible users should _not_ use -bravo recovery images(!) just outlining how I made it work to help you find a solution

[Q] endeavoru cannot flash recovery

I previously managed to flash clockwork and sentinel. Now my recovery is corrupt and I cannot flash the recovery (or boot) .img..
I get the error 0X3000 remote fail when I try fastboot flash recovery recovery.img (the name of my ROM).
I cured this on the first install by fastboot erase cache. this now gives the error failed remote err )x 1900000
fastboot devices gives me the device name.
So my recovery is corrupt, and I want to flash a new recovery and then a new ROM.
Thanks

Managed to get recovery working but could not mount usb no drive E: error.
No backup either, even though i did one, files missing.
Tried to install zip, but lots of directories missing.

Recovery was clockworkMod (the version with chargimng and full USB).
I eventually rebooted my PC and could then erase cache, flash recovery again, mount USB from recovery and reflah boot, now alls well.
(Except no keyboard
So looks like the errors were PC related.
Ha..ha..okie...glad that its finally resolved

Dead Device

I have an issue that I cannot for the life of me fix. Last night my wife’s phone received the OTA update and her phone would not restart after that. Total B.S. move on ASUS’s part not to pull that update knowing the issues people were having. But anyways, here’s the rundown. I can boot into bootloader mode but I cannot get into stock recovery. I can, through a certain method get into CWM recovery and I can see the external SD, but I get errors when I try to flash an update or another entire OS. I’ve tried to bypass signature verification also and still cannot get anything to install. ADB will not sideload because it does not find my device, but the method of getting into CWM recovery is done through ADB so I’m confused there. Never have I had such a tough time restoring a bricked device. Samsung, no problem. Huawei, no problem. This POS I’m about ready to throw in the pool and call it a day. Does anyone have any suggestions?

Open ROM archive with app (for example WinRAR),
navigate to META-INF\com\google\android
unpack updater-script
open unpacked updater-script with any text editor (I use Notepad++)
remove first line with "(!less_than_int..."
save file
put unpacked file back in archive overwriting it
put rom package on sdcard
flash it via recovery
btw, Updating IFWI takes a 10 or more minutes so wait and don't panic
I'll try that when I get home

Try and install twrp recovery through adb you can find how in the forum....if you can install it it will be much easier to flash a room.

Still doesnt work. E: error in external sd blah blah blah, same as everything else.
@MikeyLee I had the same problem this morning, i spent a lot of time to fix this, i couldn't access the recovery, i tried to flash thetered recovery and do factory reset, flash again the rom, but nothing.
To fix the bootloop i just rebooted in fastboot mode, launced the adb from pc and format cache partition, thats all.
And the strange thing is that i didn't loose the data, Although I did the factory reset, that's mean maybe a corrupted cache partition that maked impossible to flash anything or do factory reset.

I've wiped cache multiple times. What steps did you go through?
Use the adb fastboot, command "fastboot erase cache"
Sent from my ASUS_Z00AD using Tapatalk
You need the stock recovery as the same version of the firmware you're sideloading, flash the recovery through fastboot.
I was finally able to restore everything. Stock recovery, OS etc… Here’s what I did.
Using ADB and following the procedures here http://forum.xda-developers.com/zenfone2/help/how-to-upgrade-cn-version-to-ww-t3101556 and using fastboot, flashed the recovery.img, boot.img and droidboot.img in that order. That gave me stock recovery back. Then I sideloaded with ADB the latest FULL firmware from here https://www.asus.com/support/Download/39/1/0/13/Lk0Sg1Ulh0Ph49Hl/32/
It was the only version that did not error out in some form or another. Everything is back to normal.

TWRP Can't Mount /System - OP3 Bricks When Trying to Flash New ROM??

I'm currently running my OP3 on Resurrection Remix 5.7.4 (MM 6.01), the phone has the latest version of TWRP and I've flashed other ROMs in the past without any issue
RR has proven to be quite unstable for me, the system UI keeps crashing, which renders the phone unusable until after a reboot so I wanted to flash Freedom OS as that worked quite well for me previously. When I tried to flash the ROM in TWRP the ROM seemed to flash successfully but when I rebooted, only the boot logo showed and then the screen went black and the phone refused to respond at all for about two hours, after that exactly the same thing happened. I managed to boot into recovery and tried flashing a different ROM but the result was the same every time, the only way to get the phone to work normally was to flash RR again/restore from a Nandroid backup, either way, the result is the same, I'm stuck on an unstable ROM and I don't know why, the last time I flashed these ROMs they worked fine, I followed all of the instructions for flashing said ROMs to the letter, I have the latest version of TWRP, etc.
Also it seems TWRP can't mount /system, in TWRP under "mount", system is unchecked, I checked it and tried again but found that whenever I rebooted the phone or attempted to flash a new ROM, it would always uncheck itself and flashing the ROM would fail, however strangely flashing the same version of RR was always successful. Is this why the flashing keeps failing and does anyone know what the problem could be?
Thanks!

Go into your bootloader and format system, cache, and userdata (This will wipe EVERYTHING so be sure to backup). Then latest official flash stock rom and reboot. This should fix it. If this helped hit thanks!

Bootloader? There is no option in the bootloader to delete everything as far as I can see, do you mean in recovery? And if I wipe everything off the phone, how do I get the stock ROM onto the phone to flash it? When you say wipe userdata do you mean wipe internal storage or am I misunderstanding and you're telling me to wipe the usual dalvik, cache and data as you would for a normal clean flash?

No, go into fastboot and plug into pc. Open cmd and type "fastboot format userdata" "fastboot format cache" "fastboot format system"

Thank you, I am now running OOS, hopefully everything else will go smoothly now, planning to go back to FOS again
I didn't even have to use the fastboot commands to format, just sideloading the OOS file wiped everything anyway
Turns out the issue isn't actually fixed, "system" still appears unchecked in TWRP. Could the fact that I didn't actually format everything first have made a difference, given everything was wiped in the process anyway?
Looks like I'm going to be living the sideloading life...
Edit: Sideloading freedom OS failed, ended up having to restore from my TWRP backup. I don't know what I'm going to do, my main reason for using custom ROMs is installing a black theme, and OOS doesn't support Layers or Substratum fully so I can't stay on that
Is the thing that says "mount system as read-only" enabled in the mounts menu? /System isn't ever mounted when TWRP starts, you have to manually mount it, but as long as the updater-script tells /system to mount, it will. However, if that option to make it read-only is enabled, then nothing will ever write to /system. Last resort is deleting the .twrps file from /sdcard/TWRP folder to remove current TWRP preferences and then when you boot into TWRP, that first screen has the swiper to allow modifications, and you'll swipe that

It isn't set to read only, I have tried updating and resetting TWRP but nothing has helped, in fact it's got worse, I managed to sideload OOS but my attempted install of FOS failed so I tried to restore from a backup and that also failed, something which didn't happen back when I was on RR.

Which version of TWRP are you running? The official 3.1.0-0 is good for OOS and OOS based ROMs only. Try eng.stk's version.
Use the latest eng-stk twrp.
https://forum.xda-developers.com/devdb/project/?id=15934#downloads
In recovery go to Wipe > Format data (this will wipe ALL in youre phone).
It's youre Data in F2FS? If yes you must change it to ext4, in recovery Wipe > Change file system. Reboot recovery. Check if it's changed.
Reboot to Bootloader (Fastboot). From PC reflash recovery.
Now copy Oos rom to the phone memory. Flash rom. Reflash recovery (the rom will overwrite the recovery). Reboot to recovery to see if it works. If not do it again.
I sugest to NOT restore old data. This way you'll have all new in youre phone.

The recovery was working at this point, the issue turned out to be the data partition, system was formatted to ext4 but I didn't realise data was in f2fs which caused the problem in the first place. I formatted to ext4 and everything worked, I was able to install paranoid android and everything worked...
...until I flashed the wrong firmware and now I've hard bricked it! I'm going to try the hard brick toolkit
Edit: After 12 hours of being an unresponsive brick, the phone suddenly booted, system doesn't work but it has recovery. Unfortunately I seem to be back to square one, if I try to flash something it appears to succeed but then the phone doesn't boot up into system
So I am now back to the original issue of system not mounting, in terminal if I type "mount /system" I get following error:
"mounting /dev/block/sde20 on /system failed: Device or resource is busy"
Anyone know how to solve this?
I formatted everything, reflashed recovery and tried to flash OOS, got following error:
Code:
[FONT="Courier New"]"This package is for OnePlus3 devices, this is a oneplus3t" (it isn't)
"Updater process ended with ERROR: 7
Error installing zip file /sdcard/OOS3.2.6.zip" [/FONT]
Issue was "solved" by flashing PA, GApps and the correct firmware
Hopefully that's the end of all this drama, thanks to everyone for their suggestions
Hi, I'm pretty new at rooting and I seem to have a similar error. I'm getting the "can't mount /system" error in TWRP. I am able to boot into OOS 4.1.3 and run the nandroid backup but, I keep getting the same error and am unable to select "system" when choosing the mount option in TWRP.
Do I need to have all partitions in f2fs? My system partition is in ext4. Is this what solved your issue?
It seems my phone is functional even with the error active but, I've been trying to get systemless SuperSU and MagiskHide working and I think that's what is preventing me from doing so.

Cannot Install Any Custom Rom

I recently unlocked my bootloader after waiting for 1440 hours. I am/was currently on MIUI 10.0.1.0 but wanted to install a custom rom like lineage 15.1. I installed Red Wolf TWRP and then tried to install the rom. I went to Advanced Wipe section of the recovery and checked Dalvik, Cache, Data and System but not Vendor and Internal Storage. It wiped those partitions without any error. But after that i tried to install the rom but halfway through install it ended with "Update Process Ended with Error 7" and a line saying "Failed to Mount /system (Invalid Argument)" and changed the system partition size to zero. I had to repair it and flash MIUI back using fastboot.
I did this same process over and over with different recoveries ( RED WOLF, ORANGE WOLF and even official TWRP) and different builds of lineage (rom zip was never corrupted) and even with ressurection remix but still failed and same thing happened again and again. Am I doing something wrong in the process? I didn't flash lazyflasher as I read in multiple threads that it is not necessary if flashing a custom rom. Please guide?
I hope it works for my English.
1- mount > select all > restart recovery
2- full wipe > install rom and gapps > format data

Thanks for replying. You said full wipe. Should I include vendor as well or just regular (Dalvik, Cache, Data and System)?

I recently unlocked my bootloader after waiting for 1440 hours. I am/was currently on MIUI 10.0.1.0 but wanted to install a custom rom like lineage 15.1. I installed Red Wolf TWRP and then tried to install the rom. I went to Advanced Wipe section of the recovery and checked Dalvik, Cache, Data and System but not Vendor and Internal Storage. It wiped those partitions without any error. But after that i tried to install the rom but halfway through install it ended with "Update Process Ended with Error 7" and a line saying "Failed to Mount /system (Invalid Argument)" and changed the system partition size to zero. I had to repair it and flash MIUI back using fastboot.

OK. I will try your method and will report back.
Update: I tried your method but still failed. Any other solution will be appreciated.

I again tried the process as follows:
Flashed MIUI 9.6.4.0 with MiFlash using clean and lock option.
Then I unlocked it again using miunlock.
Then I flashed RedWolf v28 beta recovery by booting it and flashing it from inside recovery.
This time I flashed lazyflasher and checked options disable dm-verity and force encrypt in recovery and installed magisk. It did it perfectly.
Then I went to Advanced Wipe Section of Wipe tab and checked all the option required like cache, dalvik, data, system and even vendor. It wiped it without any problems like always.
But here the same problem starts to arise: when I again tried to install lineage 15.1 (downloaded latest build this time too) it starts but after halfway through it says Updater process ended with Error 7
Cannot install sdcard/lineage-build date and version
and Unable to mount /system (invalid argument)
When i restart recovery system partition size changes to zero and I have to repair it by changing the file system option.
Currently now I'm on MIUI 9.6.4.0 with RedWolf recovery (options disable dm-verity and force encrypt are enabled) and lazyflasher and Magisk installed. I can use my phone when I flash MIUI 9 or 10 using but it not letting me to install any custom rom. I'm really frustrated.

When you get the mount error, come to the home page and get to the mount. speak enable all options enable all options. speak restart recovery restart recovery. make format data
Not sure if the link is forbidden? I can't tell you sorry. https://www.youtube.com/watch?v=dzrWkjOfndA&t=501s
I have read replies and everyone is sharing his bit of suggestions, here are mine
1. boot redwolf as FASTBOOT BOOT recovery.img - (if you arent already)
2. change file type of /data partition to-from (xFat to ext4) and wipe all partitions (internal storage can be skipped)
3. instead of linage15.1 same package, try downloading some other custom rom, i recomend DotOS2.5 or Crdroid4.6.2
4. uncheck enforce md5 bla bla while flashing zip.
i hope you will succeed
