[Q] Factory Unlock HTC One M8 Softbrick HELP!

HI,
I just bought an unlock htc m8 no branding any where. I unlocked the bootloader and flash a custom recovery but when I tried to root the phone something went wrong because I'm stuck on the boot screen and it would not go past it. I have been looking every where how to fix it, I don't have a nandroid back up and don't know which one to look for. Is there a way to restore it back to normal? I also tried flashing a custom rom but it gets stuck in the same place.
please help.
thanks.

Have you flashed a custom recovery on the device? If yes, just try to restore a nandroid back from @Mr Hofs thread and your phone will be fine

Problem is, I don't think there is any nandroid backups available for his device LRA__001. First time I've seen that CID mentioned. Going by MID doesn't help much either, I think the Verizon has the same MID. Going by the "product: m8_wlv" it also indicates Verizon. I do see that he's on AT&T on his profile though but...
Being stuck on bootloader screen for 10minutes or more won't be surprising at all if he flashed a 2.xx.xxx.x firmware based custom ROM instead of a 1.xx.xxx.x version. Need to upgrade firmware in order to do that.
You don't happen to recall what version software your device ran?

Hi, I had the 2.7 TWRP recovery but found the 2.8.0.6 works better. I was able to flash PA ROM and it is working now. Plus now is rooted and S-off and super CID.
The phone has no branding and bought from amazon as unlock from factory. But is funny you mention Verizon has similar IDs because when I plug the phone to HTC sync the first splash screen shows Verizon wireless assistant and then go to the normal HTC one.
I tried the latest HD ROM and it was force closing a lot so I think the firmware is 1.... Something. I want to upgrade but don't know which one to get. Maybe I should look on the Verizon forum, thanks for letting me know that.
I spoke with developer support at HTC and they told me they will help restore to stock and escalated the call. I will let you know if they do help.
Thanks for the replies.

Honestly if its that much of a hassle, you should stick with something safe, Change the MID and CID to a Dev Edition/Europe, to do a full convert and you wont have to worry about the LRA_001. If you do those 2 steps the the OTA will be automatic as follows.
Else just flash a custom recovery, wipe data/cache and so and restore with one of the TWRP backups posted around here and you'll be good to go :good:

Cool I will try that. I did not know that.

Don't forget though, best steps as follow, change MID, CID, restore via TWRP backup. If youre in Europe then change the MID to EUR, but the CID change it to super CID. Youve gotten past the hardest part which is the SOFF so everything is a breeze from there on out.
You won't lose your internal data if you do any of the following steps but dumping them on your SD card would be safe too.
I had an SG manufactured one, and the OTA came out pretty weird, was an unbranded one too. changed it to Dev/Unlocked MID and the super CID, downloaded the B_US002 TWRP dump thats posted here and restored that. Might want to download the OTA too aswell would save massive time after the first 159MB ota.

Awesome. Thanks!

was any one here ever able to get things working?
i am on LRA__001 and got my radio to stop working, no phone signals
contacted HTC dev and they provided me a zip, flashing that didn't help much, still no signals and can't boot into stock recovery.
seems like i've flashed the wrong hboot or something that's causing everything to be flashed on wrong partition addresses.
any help ?

This isn't the same issue as the OP. You flashed the wrong firmware which is much more serious. This thread isn't relevant to your issue, in addition to being over a year old (which also most likely won't help your issue).

I am just trying to trace ppl with the same variant so I can request them to dump couple of partitions for me. and there is no relevant thread for this particular variant, some says it s bluegrass some says its verizon variant, but according to HTCDev its actually rural area variant.

The LRA version is the LRA version. there's no question there. Its based on Verizon, but its not Verizon.
Sounds like you are trying to make up solutions. What you need is LRA firmware or RUU (RUU may not exist).

i've got complete RUU from HTCDev to flash via hboot, did flash that but lost the IMEI and baseband version under settings > about, however the getvar all is still showing that information. so just trying to figure out what went wrong. either something is missing in what they have provided. or the hboot version is mismatching.
read bout the boot process and got to know that hboot reads IMEI and baseband while booting up and holds into some shared memory variables which later read by kernel.
just trying to figure out things and also looking for somebody who can provide dumps so i can try flashing them.

You flashed a hacked Verizon RUU. Its not the LRA RUU, and its also not an official RUU.

No I explained them my case and they asked to couple of days time and then they provided a zip file to flash via hboot. They claimed that they have prepared this file especially for me. I flashed that file. It was 5.0.1 with almost all the images.
One thing that I doubt is that the hboot is not updated since the android-info.txt says hbootpreupdate=12 and my getvar says 11 so just wondering whether it was updated or not.
Also I dumped mmcblk0p3 (board-info) and I can see my IMEI there too.
Just don't know where to nock my head

they send me the wrong files a couple of times. But they did get me the right one at the end. it seems you have the same problem I did. I still the hboot file and the system image. The hboot zip should be installed on download mode and the system image should be rename to OP6BIMG.zip and put in the sd card and re-start the phone in bootloader and let the zip install itself. It takes a long time but it worked. I have the files in my google drive I don't mind sharing it.

wi-fi not working on M8

Hello,
I want to buy a second hand HTC M8 and it has a issue with wi-fi.. it won't turn on or connect to wi-fi. from the screen shots i see that it has network (3g network). the guy selling the m8 says that a friend of his tried to put a custom rom on the phone and after that the wifi stopped working. here are the printscreens send by him. could you tell me if i can repair it myself or it is the wi-fi chip damaged.

Wifi doesn't work because the ROM is 4.4.4 but device is still 4.4.2
(can see this from the baseband version)
You can easily fix this by put in correct ROM version

can it be done without s-off? with a ruu.exe?

This s the bootloader

No need S-Off.
Get info on fastboot getvar all for this device then we will know whether to use RUU or stock backup

i'll buy it tonight and after that we'll be talking here hope for the best. thanks guys.

You better remove the 3rd pic where it shows the IMEI no. & Serial No. Those are sensitive data.
Anyway ... checked your IMEI, it is a EU version, so there is a RUU available which you can directly update it to the latest Lollipop version 4.16.401.10

thanks. will remove those pictures. i will but it tonight.

Is it for a good price due to WiFi not working? If so, the devil on my right shoulder says it serves them right for modding the phone without doing the proper research! Or researching properly to (easily) fix the problem, for that matter.

the price is ok. my old htc m7 + 100 euro

Help me to get it stock please !!

Remove serial no. in your post
I'll write simple guide on how to get back on stock and update to the latest lollipop when I'm home in next 3 - 4 hrs (if no one attend to this yet)

i see that the phone has Vodap001 CID but the soft on it (rooted one) is for the HTC_00x CID.. problem? i have got a stock backup, unzipped it, putted in TWRP backup folder, now i restore it and after that flash the stock recovery?? is that all?

It's a Vodafone UK M8, but still easy restored to stock
To be honest, I'd get it back to 1.54.161.x using the backups @ckpv5 will post, S-OFF with Sunshine and then convert it to the unbranded handset using the 4.16.401.10 RUU (using the guide in my signature)

skirmish please .. one m7 i could do it with no problem but this guy kills me

Can't write proper guide as I'm driving....
Follow this guide : http://forum.xda-developers.com/showpost.php?p=59034701&postcount=4
But don't use that 3.29.161.9, you need to restore 1.54.161.10 and its recovery then proceed multiple OTA up to lollipop 4.19.161.2
You can get the needed files here : http://forum.xda-developers.com/showpost.php?p=58606328&postcount=4278
Note : if you have plan to S-Off your device, do it after restore 1.54.161.10
if you want to keep it S-On, just proceed OTA. Later you can install any custom lollipop ROM if you want to

you could follow my guide on the viperone thread , steps 1 to 6 would get you onto stock android lollipop with a stock recovery , just do a full setup at step 6 , my guide proceeds past this point to then install a custom recovery and a custom rom but if you stop at step 6 after setting up the phone you will be unbranded stock
hope this helps

You flashed a rom that wouldn't work on Sprint device by default. You need proper kernel to run with this ROM but I will not go further on this.
Your best bet now is install RUU meant for Sprint.

Thnks for your reply sir , i was trying to do this , but now my phone cannot connect to the RUU installation wizard , How can i do it

I'm not on PC .. unable to write proper guide.
The easier one for you is download 0P6BIMG_Sprint_HTC_One_M8_4.25.651.14_RUU.zip
then rename it to 0P6BIMG.zip and put it on your microSD, not in any folder.
On bootloader, press power once to go to hboot. Once on hboot it will scan the file and ask whether to update. Volume up to update and let it do its stuff. Once completed, reboot.
After setup complete, delete that zip file.
Before that, if you select to go to recovery, do you still have TWRP ?
If yes, boot to recovery and make backup of your internal storage as the above procedure will wipe everything on your device except microSD.
Or you can install any ROM with sprint support (like the one I'm using now) then you don't need RUU.
After completed and ROM is booting, you can install any other ROM with Sprint support.
But it's best for you to update your firmware to Marshmallow first.

thnks a lot , i'm going to do this steps seems easy ,
the last part that i didn't get , how can i update my firmware to marshmallow first ?

ckpv5 , got the ruu file and rename it and copy it to sdcard , but when i go into HBoot it says
Image Update Fail
Parsing ...
Device Halted due to large Image Update Fail
press power to rebbot .

You downloaded the one that I mentioned ? I made a mistake there (wrong file copied).
You need the one that have 4.25.654.14 in it, sorry.
When I said update to Marshmallow first, that's after you fixed current problem.
After you successfully installed 4.25.654.14, then do OTA to 4.25.654.18 then later to 6.20.654.3
(That's why I don't like to help when not on PC.. sometime copy wrong filename)

Having trouble flashing ROMs, possible firmware issue

I was running ARHD 45.0 with no issues today. While I had converted this phone to a GPE edition a long time ago, it was running Sense for the past couple of days and Cyanogenmod for about a year before this.
I wanted to replace the black Google image at boot up to the stock HTC one. I followed step 3 in this guide - http://htc-one.wonderhowto.com/how-to/return-your-htc-one-100-stock-unroot-update-0160374/.
After I did that, the phone would no longer boot. (I realize now I installed the whole firmware file and not just the boot screen).
I installed TWRP, tried to sideload ARHD 45 and after the install went to 100%, the phone screen would go black and be unresponsive (except the phone would vibrate once when pressing the power button).
Other than this, I've tried sideloading CM 12.1, my stock ROM from my carrier, all with no luck.
I'm assuming my firmware and Model ID aren't matching with the ROM I'm trying to install? (Although I've used ARHD with the same Model ID, so most likely firmware related).
I have no idea what to try next and any help is appreciated.

after you have a fully working device flash TWRP 3.0.2-0 and flash a custom rom if you want
And why you using outdated roms ?
as the roms you mentioned have many updates

Thanks for your help. I'll give that a try.
These are just ROMs I already had on my computer and some that I just preferred (with ARHD, I preferred Lollipop over Marshmallow).

I got this problem fixed and I figured I'd update just in case anyone sees this post and has the same issue.
I tried flashing the RUU that was posted in this thread and ended up with the error screen that has 4 triangles with exclamation marks in each corner. I then found this post - https://forum.xda-developers.com/showpost.php?p=66077791&postcount=2 and installed the firmware that is in this post.
After I installed the firmware, I rebooted my phone and was able to access the usual bootloader (with the options for fastboot, etc). From here I was able to flash TWRP, then I sideloaded Android Revolution HD and everything worked.

That's odd. You linked my post, which was in reference to "converting" the phone to US Developer's Version. So you are now running the US Dev Ed firmware; when it was Euro firmware before. I suppose if everything is working fine for you, you may as well leave it alone.
Also, flashing firmware is typically no necessary to run the Euro RUU (its a peculiarity to US variants).

Soft Bricked M8 in need of help badly

Hi there in need of some help. I have really ****ed up my install of twrp and supersu from my htc one m8.
I followed this person tutorial htconeroot com/htc-one-root I followed everything to the letter apart from enabling Dev enable usb debugging.
1st of all I downloaded this twrp file "openrecovery-twrp-2.7.0.2-m8" when I should have downloaded the latest version of twrp. Such a noob mistake I know now : (
2nd I also downloaded a older version of supersu SuperSU-v2.79-201612051815 which I loaded onto my phone and should have downlaoded the latest version.
I followed all the instruction on the video and when I rebooted after instaling supersu my device is now stuck on the HTC startup screen.
I tried to reboot again going into fastboot and recovery and nothing worked. I know I should have just updated supersu to the latest version but I followed some other peoples advice and now I have completelty screwd my phone I think.
I deleted supersu from twrp and wiped the files as well. My computer now does not recognise my phone folder to be able to install any updated version of supersu or install a ROM. My computer OS is windows 10 and it now sees my phone as a cd drive so cannot install anything on the drive at all.
I can get into twrp but nothing seems to work when I try to reset back to factory settings.
Is there a command line way in geting back into my phone and being able to sort this mess that I have made.
In need of some serious help from the experts here at xda developers.
All help is very much appreciated.
Thanks Steve

These random "root" websites just copy content from XDA, and have little or no community to help you. All you need is on XDA, so I recommend stick to XDA.
Such "root" websites also don't give enough information, aren't well organized, and don't update it all. So they are very likely to get you into trouble, as you now know.

What version, if it wasn't SuperSU 2.79?
What version of Android was the phone on when you started? Was it Marshmallow?

There is really no such thing as "reset back to factory settings" especially in TWRP. Just going in and wiping things, isn't going to fix the problem.
Try to fastboot flash an updated version of TWRP. If you were on Marshmallow, try current version 3.1.0-0 from there: https://dl.twrp.me/m8/
Once booted into TWRP, see if you can access the internal storage from your PC. If not, make sure internal storage is checked in "Mount".

Sorry was this version SuperSU-v2.37.zip. I do appologise thats the latest version that I posted and was ment to be this version SuperSU-v2.37.zip this is the one that I installed.
Yes it was marshmallow.
I downloaded the latest version of twrp and can I ask how to re install twrp ??
I cannot access my phone internal storage for some reason my computer is not recognising my phone now. It was before as I installed supersu straight onto my phone internal storage and tried to boot the phone from that. It's now coming up as a cd drive and I cannot access to install anything on it.
In mount all I have
System >>> not checked
cache >>> not checked
Data >>> is checked
Micro SDcard >> is checked
USB-OTG >>> not checked
Thanks again for your help
Steve

Flash with fastboot. Which I would assume is the same way you did it before. Instructions on TWRP's website: https://twrp.me/devices/htconem8gsm.html

Let's get the right version of TWRP on the phone first, and see if that helps. If not, we'll go from there.

Updated twrp
Hi just to let you know that I have booted into the new twrp. I am using FWUL and using simple-ADB and it installed it no problem.
Just cannot seem to find how to install supersu onto my device as my phone is not showing up FWUL OS.

Sorry, what is FWUL?

Updatefor you
Hi just to say that I installed supersu as well the latest version SuperSU-v2.79-201612051815. After rebooting I am back to the htc page. I have no ROM installed at all on this and it's saying there no OS installed on my phone.
I want to install kali Linux Nethunter and I have downlaod the correct files to install.
WillI have to install another OS like Marshmallow or kitkat before installing Kali Nethunter.
Thanks again for yourhelp : ))

[LIVE-ISO][FWUL][STABLE] adb/fastboot without any installation and driver issues
[F]orget [W]indows se [L]inux
Did you not send me there to download it lol : ))

You must have at some point in trying to "fix" the problem, wiped system in TWRP. System is same as ROM/OS. So if you wiped it, it's pretty obvious that no ROM is the result.
Flashing old SuperSU in itself doesn't result in no ROM/no OS. It just makes the phone stuck on boot screen, and flashing the proper SuperSU will fix it.

I've never used it. But reading the thread, it looks like you need a fully working OS. So pick a ROM, put it on the phone, and flash it. Then flash Kali Nethunter.

Ah, I see it's listed as one of the several options for adb/fastboot in the TWRP install instructions. I've never used that specific one, so the acronym confused me. Any fastboot/adb environment will work about the same. You didn't really need to install anything new on your computer. You already had fastboot on your computer to begin with (to unlock the bootloader), and that would have worked fine to install TWRP.

BackUp File
Hi there and thanks very much for your help very much appreciated. Before I did everything I made a back up and have the files on my desktop they are:
0C77AEECE8C258113148C6FB487946BF97B34672
01C669ECF50A775226B15B9F60EEB522AB34BE2F
I have ten of these files and a deafault file as well. Can I restore these to my hpne at all.
I am going to try and install marshmallow on my phone as that was the last OS that I had. Do I have to have the most current and updated version MM.

What did you use to "backup" the phone? Those don't look like TWRP backup folder names. They look like MD5 verification codes?
Individual TWRP backup folders will usually have name format of the date/time the backup was made, such as: 2017-04-22-20-43-56....

There weren't many different official versions (maybe 1 or 2) of Marshmallow for each M8 carrier version. Any version MM should do.

You may have outdated firmware and outdated TWRP version. Most of current ROM won't get installed on outdated TWRP.
