[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.

[Q] One M8 HTC__001 CID, Firmware/No Wifi problem

Hello, I've been a long time xda lurker (Never thought I could really add much anyhow) since I had my Dell Streak and I think for the first time since I got my M8 I need a bit of help.
They rolled out the lollypop OTA update here in Ireland and figured It was time to update to a stock ROM from here or a slightly improved one but ever since then I have lost my WiFi completely.
Sorry If this makes no seance- at all I'm a little burnt out trying to solve this on my own but even going back to 4.4.3 ROMs I still have no WiFi at all and any help at all would be greatly appreciated.
This is all the info I took from fastboot and the bootloader I thought would be needed

Thanks again for even looking!

First - remove the serial no. & imei no. as those are sensitive info.
The details that you have does not show that you did OTA. You are still two versions behind.
Restore your stock ROM, flash a matching stock recovery (no custom recovery) then do OTA ... multiple OTAs up to the latest 4.16.410.10

If you're willing to set the phone up from scratch you can just update straight to Lollipop using the RUU available on here. If you want to go that route then you can following this guide I wrote:
http://forum.xda-developers.com/showthread.php?t=2735235
Basically, step 3 covers what you need to do as step 1 and 2 are already done and at least once that's done if you still have issues you know it's not the software on the phone

I will try that right away thank you for your help I'll post back here when I'm done

No luck, kept getting error 99 with the 'htc_fastboot" from the thread and with my normal fastboot it gives me the error 32 'header error' I only noticed the thread was for s-off phones, I don't care about my phone saying tampered, unlocked or anything but I'm assuming that's stopping the flash from happening.

You must relock your device first ... then try again with flash the ruu.zip

Haha yeah that worked now, ignoring the guide at the start and just leaving it with the relocked warning it's flashing now via the RUU
Thanks to the both of you for your help.

Various problems.!

Forget this sorted it all out, now running SRom ported lollipop with sense 7 from the M9. Hboot no red text and faux locked/original/son. Super CID.
For the record, it's always a firmware/dalvic cache problem (98%)
Hi Guys so Im rooted running Android Revoluton HD ROMs on an international O2 phone S-on
I thought I would wipe the entire phone, bleach it like a PC and reinstall.
Not a problem except various elements dont work.
I installed Stock ROM (I think KitKat)
I installed ARHD 22. (Kit Kat) everything worked
I installed ARHD 34.(Jellybean Sense 6) no wifi
I installed ARDH 40.(Jellybean Sense 7) no HTC TV
I installed ARHD 41.(Jellybean Sense7) no images in Blinkfeed?
I know its probably because I wiped the misc folder but up until I did a clean wipe I could use all of these roms without a glitch.
So is it firmware?
What do I need to put back on my phone for them all to work
I am S-on at the moment and I know that isnt whats stopping these roms working.
Any suggestions?

It's firmware. You most probably have kitkat firmware and lolipop based roms will mess up your wifi and stuff. Take an ota or stay on kitkat.

Thanks will try
Do I just flash the zip file?
Im sure I probs do

If you are S-ON don't flash firmware. Just don't. You can flash rom zips, recoveries, kernels. You can write on these partitions with s-on: recovery, boot, system and data.

I've just used Sunshine to get S-off, what a joy to use!
So now I can just flash them right?
I've got my cid number matched it up with the ota and bingo?
Right?

well im come from HTC One M7, and as long as the M8 is pretty much the same, you dont need s-off to flash the same firmware which your already on, or the next one step up, after all, this is exactly what an OTA does for you.
However, now your s-off anyway, you canflash any RUU or firmware you like, just make sure cid and mid match first. :good:
EDIT: there ia also no need to lock or re-lock the bootloader to flash anything now that your S-off, leave it unlocked all the time for everything, its a common problem on the M7 forums at the moment, people who are s-off or even s-on, locking bootloaders with custom rom's or recovery's on thier phones.

Thanks, so with the ota there are two for O2 my cid is O2___001 am I right that I can take the 001 OR the 002?

in all honesty, I would of thought the CID 001 and 002 were in the same ota, have you checked the android-info.txt file within the OTA itself, its just a zip file.
possible to post your fastboot getvar all without imei and serial number please, also a link to the OTA's your downloading would be good.

Well I've just tried to flash both....I enter recovery instal zip right?
It's giving me an error.
Will tell you that info in a minute when I get on my pc

personnaly, if your just trying to get to Lollipop, I would change my CID to HTC__001 (thats 2 underscores, CID is always 8 digits)
Change MID if required.
and then flash the WWE International Lollipop full RUU, piece of cake. http://forum.xda-developers.com/htc-one-m8/general/htc-one-m8-european-signed-ruu-0p6bimg-t2911563

But if the original isn't flashing what hope have I got with an HTC one. It's interesting to know though that I can change it.
So what next?

Flashing an OTA manually is a different kettle of fish, its just an OTA not a full RUU, and you would still have to be full stock in order for it to succeed.
however, if you just require the firmware in order to use a custom LP rom, then just pull the firmware.zip out of the OTA and flash it.
you would then have to put a custom recovery back on your phone, copy a rom to your sdcard, and flash it from within TWRP recovery.

And im trying to flash O2 OTA

you already have the latest firmware on your phone !!!
I installed ARHD 41.( Sense7) no images in Blinkfeed? ------ pulled from your first post, this is a common problem, if you mean its face ache, there is a fix for it on playstore.

OK is tere an RUU for O2 uk?
So im extracting the firmware at the mo, then I will flash it then I will try and install ARHD 41....
Im right that the O2___002 is an upgraded version of the 001 and its what I need right?
Otherwise im just replacing like for like.

nope O2___002 is a different cid, you need to use the 001 files, however, its the same as you already have on your phone.
CID is just carrier ID, so O2___001 will be something like O2 UK and 002 might be something like O2 france, no difference in files, just different regions.

nope its not your firmware, just checked a cid list, 002 is O2 DE, 001 is O2 UK http://forum.gsmhosting.com/vbb/f485/archive-htc-cid-list-1604812/
Make sure of a couple of things when flashing a custom ROM, check for problems other are having with it, by reading some of the later posts is what I always do, just a few pages, also and this is a must, read the OP's flashing instructions, so many people bypass this step, the most important step is to make sure your using the dev's recommended custom recovery for flashing.
I always full wipe before flashing anything, so in TWRP first factory reset, and then goto wipe - advanced - select everything except your internal storage and SDcard, and then always reboot back into recovery after the wipes before flashing the rom, it will nag you and say you have no OS installed, ignore it and Do Not Intall to SuperSU, the custom rom flash will do that for you.
During the rom installation, again I always select full wipe when given the option, you then know you have a clean slate to build the rom on.

Your firmware is already current, and should work with latest ARHD. Blinkfeed not showing image is a known issue reported by others.
No need to mess with RUUs or firmware zips.

Help returning my M8 to stock.

Hi guys,
Apologies if I'm posting in the wrong place or if this has already been answered. Google suggests this is a common theme, so I hope you'll bear with me, but... I'm a bit of a beginner when it comes to rooting, and it's been some time since I rooted my M8 and I've forgotten most of what I learned.
I'm looking to 'unroot' my M8 and restore it to factory settings, for two reasons. Firstly, because it will allow me to receive OTA updates which are currently not happily installing (I assume this is due to my having rooted the device). Secondly, I want to unroot because my bank (Barclays) offers a mobile banking app which doesn't work on rooted phones... Which is annoying to say the least, but unfortunately I've concluded that the the app will be more useful to me than having my phone rooted.
My phone is a Vodafone HTC One M8 (VODAP001), S-ON and has TWRP installed, which I did just now in my attempts to unroot.
Doing `fastboot getvar all` gives me this:
Code:
[email protected]~$ fastboot getvar all

(bootloader) version-bootloader: 3.19.0.0000

(bootloader) boot-mode: FASTBOOT
(bootloader) commitno-bootloader: 3aa067db
(bootloader) hbootpreupdate: 11
(bootloader) gencheckpt: 0
all: Done!
I hope this is useful and I've provided enough information for someone more knowledgeable to be able to help... but if not let me know and I'll do my best to provide what else is needed!
I should add that I'm a Mac user and as such any solutions which require using Windows tools would be less than ideal. However, if it's absolutely necessary I do have access to a Windows 10 machine which I'm sure my dad would be happy for me to use!
Thanks

That wwe ruu is useless. He is s-on and needs a Vodaphone ruu at least ! Or a stock nandroid backup.
His best chance is going here
http://forum.xda-developers.com/showthread.php?t=3086860
Look for a backup that has the same main version numbers as your output. Restore it and flash back the stock recovery. That's all there is needed. That way ota will install fine.
I'm not sure if there is a vodaphone ruu with that main version number available and even if you find one and it has a LOWER number it's useless as you can't downgrade via ruu due to being S-ON

yea I know that's why I say google it
Here's one

That one won't work, corrupted. See the size is small for a RUU and that already been discussed in other thread.

Thanks for the replies everyone. I'm still struggling to get my head around this, but I'm getting there!
So, am I right in thinking that all I need to proceed is a stock recovery img (which I have already) and a TWRP backup?

Yes .. you need restore non-rooted 4.19.161.2 backup and 4.19.161.2 stock recovery.img. Once done, proceed with OTA to the current latest 4.19.161.3

Thanks @ckpv5. I will have a go now and see where I get to. I have a copy of 4.19.161.2_ckpv5.zip as well as a 4.19.161.2 recovery so I think I should be all set.
Must say, I'm glad you replied to my thread as all my previous attempts had led me to your other posts/threads! But unfortunately lots of the files I was after had been taken down from mega/etc.
I'll post back with updates/questions when I've had another go

Success!
Thanks so much for your help everyone! I managed to get my phone unrooted and now the Barclays app and OTA updates are working as expected
I followed this process by @ckpv5, except I used adb to push the backup to my phone.

Great ... glad that we could help

Not easy to do thing without PC.
You have a T-Mobile device, you should be able to find a backup in T-Mobile section : http://forum.xda-developers.com/showthread.php?t=2714456
If you have PC, then you can RUU it - http://www.htc.com/us/support/rom-downloads.html
Download the latest RUU 4.20.531.5
That's all I can help as I'm not familiar with T-Mobile US device.

Unroot Help

I'm currently trying to unroot so I can update to Marshmallow. I've used the guide to try and flash a stock recovery as well as tutorials on youtube as well but I can't seem to get anything to work. I also can't find a stock recovery of my cid number which is SPCS_001 if anyone could help me find that recovery or point me in the right direction for flashing the right recovery that would be greatly appreciated.

No idea what you are talking about. No specific video is mentioned in this thread.
Also, I would suggest if you are modding the phone yourself (its not clear) you should avoid YouTube tutorials, and instead take the proper time to read and learn the processes, terms, etc. The video guides just spoonfeed you the steps, instead if you gaining any actual knowledge. Enough to get you into trouble, without any clue of how to get out.

We were messaging and he showed me a YouTube tutorial that is v the video in question. Thanks for the advice in the future though.

Case, it seems you are confusing "stock recovery" with an OS or ROM, which it is not. Recovery is just a small application/partition used to install or update the OS.
