Softbricked my HTC One M8, any advice is much appriciated

Well its been some time since was rooting and romming phones (so please give advice step by step) but just the other day I soft bricked my One M8 and I am at wit's end trying to fix it.
Scenario was I was happy running gpe 4.4.2 on my phone awhile now until I saw the GPE rom was getting an OTA update with Lollipop. To avoid the hassle of installing an ota updat the dirty way I thought to just re-lock my bootloader, flash recovery and just update. Well it went like this.
1. Had 4.4.2
2.Flashed stock recovery (I forgot to do fastboot oem lock)
3.Booted back into 4.4.2, ran update checker, downloaded 4.4.3
4.Phone updated to 4.4.3 with no issue.
5. Ran update checker again to grab 4.4.4
6.Rebooted to install and bam on boot I just got the white "HTC" boot screen for about an hour
OS is broke.
I do still have access via fastboot and have since re flashed recovery to twrp. However I am unable to flash a new rom, I keep getting "E error executing updater binary in zip" in twrp and "status 7" in clockwork.
Sideloads fail with the same error.
I've also tried re-locking the phone and flashing stock recovery and trying HTC's RUU app however that fails as well with Error 553.
Any help is much appreciated! My goal is just to have clean lollipop gpe rom installed.
What can I do to fix this?

---------- Post added at 11:28 AM ---------- Previous post was at 11:24 AM ----------
Something you can try now....you still get stuck at splash screen try fastboot the boot.IMG from the ROM you r running.

Yeah I use hangouts. And I'll be available at 7pm est today. I left the phone at home today just out of frustration of fiddling with it all night. Message me your gmail account and we'll take a look.

I might be in a similar situation. I was running blisspop 5.0 just to see how it feels. I started having problems so i went to wipe and go back to CM11 only to find out Philz E: could not mount/data to setup . Now I have no ROM and a broken recovery.. any thoughts?

Did you flash a different radio/baseband as part of this?
Are you S-OFF?

I am S off. I hadn't flashed a new radio. I found my fix. I think i inadvertantly wiped my data from the internal sd. That was throwing me off. I managed to get back to CM11. I still can't read any data on my ext SD, but at least my phone is on and stabilized. Thanks for replying!! Happy holidays!

[Q] Hi, no OS on M8, flash rom in TWRP "some symlinks fail"

Hi,
Apologies in advance because I'm sure this is a very noob problem, but I was trying to update my M8 to lollipop and ended up messing it up somewhere. It was rooted before, S-Off, unlocked, using Android HD 4.4.4.
When I try to flash the Android HD Lollipop rom in TWRP from internal or external sdcard, or from USB OTG, the installer starts and looks successful until it gets to "Creating toolbox symlinks". After that it says "symlink: some symlinks failed"
When it finishes, it goes back into recovery and TWRP says "Successful"
When I go to reboot TWRP says it isn't rooted and asks if I'd like to root. Whether I say "yes" or "no" it reboots to a white HTC screen with a little lock at the bottom. The lock wasn't there when I started. After a few seconds the screen turns off then back on, then it goes into recovery.
If I try to install the update-supersu from internal or external card, or from USB OTG, in TWRP it says "success" and no errors, but then when I go to reboot it, it says "does not appear to be rooted" and asks if I'd like to root it. Whether I say yes or no it reboots, freezes, then boots into recovery and I start over.
In boot where it used to say "tampered" it now says "modified", and under that "unlocked", "s-off", a bunch of numbers that look important, but nothing in "OS-".
I can get into recovery and fastboot or hboot just fine. I have ADB, fastboot, and I think all the drivers I need on my laptop, and both recognize my phone when it's plugged in and I type "adb devices". I've tried like 10 different guides to push and flash and honestly too many commands to remember, but nothing that can get it to boot into a working rom.
To be honest, every single time I've tried to root something, I've broken something, but usually if I keep looking I can find the same problem and someone who's fixed it and figure it out, but I've been at it nearly 20 hours straight now and I just can't see what I'm missing (besides OS Dx)
If anyone knows what I've done and how to undo it, I'd be grateful for any advice.
Thanks,
Josh
*** I think I got the wrong firmware, but not sure how to find the right one without downloading them reandomly and checking the android-info***

Boot to bootloader/fastboot then run command fastboot getvar all
Post here the result (delete serial no. & imei no.)
Will see what we can do later
Your problem most probably is the old version of TWRP (2.7.0.2) that you use.
You should try 2.8.3.0 if you have a KitKat firmware and 2.8.5.0 if it is a Lollipop firmware.

So you have a AT&T device.
What actually you want to do because there is no lollipop update for AT&T yet.
Since your device is S-Off, you can change
CID : CWS__001 to 11111111
MID : 0P6B12000 to 0P6B10000
then flash a EU firmware.
Or you take any unsigned EU firmware.zip, open it with 7-zip and extract out the android-info.txt and edit this android-info.txt to include your CID and MID (use notepad++ for this), drag the modded android-info.txt into the unsigned firmware.zip
Flash this modded firmware, should work too.
And important thing about TWRP : 2.8.3.0 if you have a KitKat firmware and 2.8.5.0 if it is a Lollipop firmware
Then you can install any of the lollipop Sense base custom ROM.

Thanks. I'll chug some coffee and give it a try.

Ok, I changed my CID and MID without too much trouble, but about "TWRP : 2.8.3.0 if you have a KitKat firmware and 2.8.5.0 if it is a Lollipop firmware", how can I tell which I have?
Oh, I used the ADB method if that matters.

After change of CID/MID, you need to flash firmware.zip in RUU mode not ADB.
Your current firmware is KitKat .. if you stick to it, you need 2.8.3.0
After you flash a 4.xx.xxx.x firmware - you need 2.8.5.0
Check this : http://forum.xda-developers.com/htc-one-m8/general/vomerguides-m8-bootldr-unlock-s-off-t2800727

Thanks for putting up with all the questions.
I just want to make sure I'm doing this correctly. I need to update the firmware to a 4x one, then twrp 2.8.5.0, then root and rom? I'm reading the guide you linked, but I'm not sure which firmware to use, for example it lists 5xxBase, then underneath it lists firmwares starting with 4xx.
Or does it not matter?

1. Update firmware, flash the widely use - 4.16.401.10
2. Flash TWRP 2.8.5.0
3. Install ROM
No need manual root because custom ROM is prerooted.
I got to go now .. be back in next 4 hrs

TYSM!! That's what I was looking for

Ok, I updated the firmware and TWRP (I think), but when I try to do anything like flash a rom all the partitions come up as unmountable before the installer starts. I know I read something similar before so I'll try to find that.

You don't seems be using the updated TWRP 2.8.5.0
Your fastboot shows that you may use the old 2.7.0.2
Download and install TWRP 2.8.5.0 - http://techerrata.com/browse/twrp2/m8
command fastboot flash recovery openrecovery-twrp-2.8.5.0-m8.img
Then boot to recovery - select wipe - advance - format data - yes
Go to reboot menu - select recovery (to reboot back to recovery
Select "Mount" menu - enable MTP
Transfer the ROM zip to either Internal Storage or MicroSD (if you have one)
Then try to install the ROM.zip

that's so weird...from within twrp the little info bar thing at the top says v2.8.5.0
Ill install again

Yeah .. unless you remove the (bootloader) version-main: info, TWRP 2.8.5.0 should not remove that after you flash the firmware.
Anyway ... try the other steps that I mentioned.

You did it man, you fixed the phone I thought I would have to throw away.

Different ways to skin the same cat. There is nothing "wrong" with the solution that was used.

It worked, and now I know to make 100% sure I have the right versions of everything BEFORE I start, so I'm happy.

TWRP straight back to BootLoader

I've recently installed Firmware and another ROM (RUU) they went thru successfully but only updated to Lollipop 5.01 which i thought was strange.. well anyway, i flashed TWRP and now it says entering recovery for about a second then goes back to the Boatloader page (fastboot etc) tried to restart and try again and it does the same every time..tried re-flashing TWRP and still does the same.. any ideas please?

Thank you

Try wipe cache, and flash TWRP again.
Make sure its TWRP version 2.8.7.0 or 3.0.0.0. Some folks have been trying to flash older versions, some of which don't work on LP or later.

Thank you, tried fastboot erase cache and flashed 2.8.7.0 and it still does the same thing.. i already flashed 3.0.0.1 before - would you know how to change the MID without having to use recovery? once i have changed that i can get the European RUU installed on my device - i have changed the CID already .. the phone was US on T-Mobile but i'm wanting it on UK O2 now ..thank you again

Did you flash TWRP before booting up at least once?
RUU to marshmallow doesn't seem to exist yet. (aka I haven't found one)
So update to 4.25 firmware which is lollipop 5.0.2 - I think.
Then allow phone to boot (make sure to have stock recovery), go through with all the OTAs which will come.
Once OTAs are completed successfully feel free to flash TWRP back.

Hi and thanks again, to be honest i dont know what i've done.. i got the phone from eBay..new M8 but when i spoke to HTC they said the phone was US on T-Mobile.. i just wanted to change the CID & MID so i can install a European ROM maybe O2 or something ..i'm really quite new to this ..i had a M7 before which i did manage to flash and update to LP but with this M8 i'm struggling .. i just downloaded Firmware 4.25.651.18.zip ..which ROM would be best to use with this please? i'm sorry for my lack of knowledge here.. and should i wipe the phone completely? factory format as i cannot get into Recovery..
Thanks again

hi again, the reason the original ROM did not instal was because i had changed the CID to a European one and was trying to instal a US TMOB ROM ..i changed the the CID back to a SuperCID 1st then installed the ROM and then changed the CID back to the original T-MOB010 CID so i could get all the OTA updates ..i will just leave it at this for now as i thought originally i had bricked my M8 - after the 1st flash the phone went into a boot loop :/ ...anyway, it's all sorted now and doing the many OTA updates but this particular one only updates to LP 5.01 .... i'm just wondering how i could get it to update to 5.02 or even 6.0? i will still try and change the CID & MID when i have enough information and am completely confident (and have a spare phone) then instal a European ROM and see if that get me the updates - thanks for the help

Perfect, so you figured it out Well Done.
Yeh, the best way is by changing MID and CID then flashing what you wish.
I wouldn't know since I am S-on.

I used Sunshine S-Off to do that.. payed the $25 ..its really easy and don't take long.
As for the phone, i think i'm going to do some serious research before i attempt anything like that again - its all up and running again, i'm not even going to flash TWRP this time until i really need it .. it's currently updated to 5.01 which i can live with.. i just wanted to taste a bit of Marshmallow i suppose it's a waiting game now - thanks again

How did you come about picking that firmware? Its not for T-Mobile US, its for Sprint.
In fact, its a good thing the firmware failed to install. If it succeeded, it may have bricked your phone due to partitioning differences between the Sprint version and most other M8 versions.
Be very careful about what firmware you flash. Don't flash any firmware you if you aren't 100% sure its the right one you should be using.

Before we head in that direction, you need to understand a couple things about changes made requiring s-off. By definition s-off means that all (or at least most) security checks are off. So this means:
1) Changing the MID is a bit risky, in that you are manually editing/modifying memory blocks (not sure if "block" is technically the right term, but I think you understand what I'm getting at) using adb. Enter the command incorrectly (and modify the wrong memory block), and you can brick the phone! You have to be extremely careful about the process of changing the MID, and double check and triple check every single commands is correct (not a single typo) before pressing "Enter".
2) As mentioned above, flashing firmware also requires close attention and care. You need to be 100% of the firmware you are flashing. Once you've changed the MID, you are bypassing the very safety check that is designed to prevent bricks (from flashing the wrong firmware).
If you are prepared to use extreme caution and exercise the required care, then we can proceed with what you want to do (change MID, flash Euro RUU so that you can "convert" the phone to official Euro version, with full OTA updates).
Although another method (if you don't mind the lack of OTA updates) is to ensure you are on LP firmware (or flash T-Mobile US firmware or RUU to get to LP firmware). Then flash a MM custom ROM (which should work fine with LP firmware). This direction is much safer, as its nearly impossible to brick the phone flashing the firmware meant for your original CID/MID or from flashing a custom ROM.
Really, the lack of OTA is not a big deal, in my opinion. The custom (or near stock) ROMs get updated just as fast as the official OTAs (in fact, often faster depending on which CID you are talking about) so you can continue to keep updated by flashing custom ROMs. Honestly, this is my 3rd HTC phone, and the number of times I've installed official OTA updates is zero, due to the fact that the ROMs posted by devs here are just as good (or better) and just as timely.

Thank you for the advice & tips... the phone is S-Off (Sunshine) and bootloader Unlocked - all i'm wanting to do is go from T-Mobile US to a UK ROM like maybe O2 ..i'm on the giffgaff which run on the O2 network ... i have been searching for the correct Firmware without success - i have RUU_M8_UL_L50_SENSE60_MR_O2_UK_4.20.206.1_Radio_1.25.21331147A1.06G_20.69.4196.01_F_release_414450_signed
but just need to find the correct firmware to flash so i can instal this.. any ideas please? am very new to this and don't completely understand how to find the correct FW for a particular RUU

I discovered the reason TWRP was not flashing properly... i needed to update to Android 5.01 1st then flash TWRP custom recovery..that all works well now and i have recovery back but just put MID_Changer_03.07.14 on my phone and ran it in recovery - it all worked great but when i checked the MID it hadnt changed so ran again an still no change - i'm wanting to change that too 0P6B1000 (Europe) then the CID to HTC__032 ...then i will try to instal the above RUU - does this all sound like the right thing to do? i have been trying to find the right firmware for that RUU but cannot seem to find one or rather don't know what i am looking for - thanks again

Are you s-off? If not, you need to be s-off to change the mid.

Haven't heard of such a method. Can you link to where you got this from?
There is a proven method for changing MID on the M8, and that is not it.

I flash differnt firmware from OP i think... i'm still none the wiser though.. my updates OTA to 5.01 but i'm sure i can get 6.0 with sense 7.0 if i use a UK ROM but i need the correct firmware for that particular ROM and i do not know what to look for - the MID Changer was here http://www.droidviews.com/change-cid-mid-htc-one-devices/ thanks

Looks like you flashed an older firmware (really old, as in Kitkat Android 4.4.2), based on Post #10 (versus what you had originally in Post #1).

That isn't for the M8. If you look at that webpage's "Source" it links to the XDA One M7 section. That mod is for the M7, not the M8.
You're lucky it didn't brick the phone. I've already stated above in Post #6 how dangerous MID changing can be, if not performed properly. But it seems that you've chosen to ignore that advice.
No offense intended, it seems you are going about things rather recklessly. Already you've flashed an incorrect old T-Mobile firmware, tried flashing the firmware for the wrong version (Verizon) and now tried changing the MID with a mod for the M7. There is a proper process to change the MID on the M8. But I'm hesitant to lead you to that (of course, you can find it yourself - but that's your own deal), as you haven't demonstrated you are capable of the proper carefulness. And frankly, I don't want you messing with things that can easily brick your phone.
My suggestion would be to flash back to 4.20.531.5 firmware (if its not the current firmware) then just leave it that way until T-Mobile releases Marshmallow. Alternately, install a custom recovery (unlocked bootloader required, if its not presently), and simply flash a MM ROM; which should work find with LP firmware. These options are relatively safe, and don't require you messing with the MID.

HTC m8 phone keeps booting into fastboot mode

hello,
after root my phone
every time i try to put it in recovery mode it goes back to fastboot mode ..
even if i tried to flash a recovery on it , it would boot to fastboot mode
even when trying to install a official htc software update it just boots into fastboot ..
now i want to get it back to stock..
please help me !!

Need more info.
What version SuperSU? What version TWRP?
What "official update" file did you use? Was it an OTA or an RUU (list the exact file name)?
Also, do fastoboot getvar all, and post the results (delete IMEI and serial number before posting).

In addition to the fastboot output, I asked 4 questions, none of which you answered.
You have the M8 eye, not the "standard" M8. Far as I can tell (not many folks on xda have the "eye") you need a special version of TWRP for this version. You can try the right version TWRP, and flash SUperSU again, see if that helps. No idea if this version TWRP will work on not (can't personally vouch for it): https://forum.xda-developers.com/htc-one-m8/general/m8-eye-recovery-root-t3159648
Depending on what you did to the phone by flashing the wrong TWRP, it's hard to tell what the proper way to proceed.

hi
can i have stock recovery download link in that phone pls

I have a similar issue, but with a standard M8
£10 off ebay, so not expecting ,much (also means no known history) . 1 week old noob reading here and flashing phones
1) only boots to fastboot, and even does this when you leave it powered off, but charging.
2) select hboot, then to recovery, recovery doesn't run, just resets back to fastboot eventually, after screen goes white not black.
3) can partially speak to phone in fastbook and get versions ok (included below)

4) never been able to boot to full o/s so not in developer mode, so cant get response in adb (and dont know how to use this anyway) That is correct, you will not be able to use adb unless you can boot to OS or alternately TWRP custom recovery. So you are basically limited to fastboot in the current condition.
5) tried RUU.exe - fails with usb error after it tries to restart bootloader There isn't a valid exe format RUU for your version number (6.12.401.4) so you are probably using the wrong RUU. What is the version number or file name for the RUU.exe?
6) tried ruu.zip from memory card - fails with partition update fail Exactly what partition(s) is it failing to update? What is the version RUU you are using? The only valid one for your version would be the RUU.zip from here: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
7) tried fastboot recovery image 6.12.401.4 and it fails to write - error is 'remote:signature verify fail' You can't flash an unsigned recovery image, unless the bootloader is unlocked. It also seems you are trying to flash stock recovery, and I don't see how that is going to help your current condition.

I think your best bet right now, is to try the correct RUU.zip which I linked above.

Full stock firmware ? Not some modded one.
You need htc_fastboot to fastboot flash ruu zip
See - https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
In case you need full stock firmware, you can check my backup thread post #5
Frankly, I have no idea why you can't flash/install RUU when on S-Off, unless the partition is GPE size (you need to resize it back to Sense using full stock firmware, then install twrp to format data (not wipe data but format) before you can install RUU)

Thanks to your firmware i managed to format cache data and system partition and install lineage 15.1
Before I couldn't do it because there was a problem with the cache partition. I still cannot install RUU, but since LOS is working I don't need RUU. Now I have only /carrier partition error in TWRP but the system is working so I'm satisfied.
