[Q] Possibly stupid NANDROID question...

Okay, so I'm a Samsung Note 3 owner that's helping out a guy to unscrew his AT&T M8. We're trying to return to nandroid stock using this guide http://forum.xda-developers.com/show....php?t=2701376, and I'm at the step where it says to flash the nandroid .zip file in TWRP. This is all fine and dandy, but even though it's located in the TWRP/backups folder, and apparently it's the correct nandroid version, it FAILS immediately. Maybe I got the wrong version??? I've googled around, but I can't seem to get the right info on this one!
Any and all help would be appreciated!!!:good:

Read that thread thoroughly ...
You don't flash the nandroid.zip
You extract the nandroid.zip and transfer the content to TWRP backup folder.
Anyway ... browse thru AT&T forum, you should be able to find the correct RUU
http://forum.xda-developers.com/att-htc-one-m8/general

No RUU will flash!!!! No main version shown in RUU utility...

I have tried a few newer RUU's since I'm on 3.16 bootloader and S-ON. When I go to flash using the RUU utility, it doesn't show any installed rom...because there IS no installed ROM!
Therefore, it fails. As you can see below...there is nothing showing in version-main. Any idea on how to fix this??? The phone isn't bricked...there's just no rom installed. Should I use TWRP instead???

Htc one m8, impossible to boot with any rom...

Hello,
Sorry for my broken English, I am French, I haven't found anyone able to help me on the French speaking forums, so I come here, sorry for the inconveniance
I recently got a 2nd hand htc one m8 for a very good price cause the seller did not know how to repair it : impossible to have a rom boot.
I don't know a lot about the past of the phone.
It has the boot-loader, it has the last TWRP as recovery.
its CID is ORANG202
VersionMain is blank
On the bootloader screen, it is written :
Tampered
Unlocked

Whatever the roms I try, however stock or not, none of them boots well.
At best with the Stock roms of the mobile operator Orange France that get flashed with success, I am stuck at the HTC logo and nothing more... Whatever the stock rom I try...
With non stock roms, the best result is given by the latest cyanogenmod rom nightly that flashes conveniently then gets also stuck on the Cyanogen boot screen.
Of course, I perform factory reset with twrp prior to any flash.
That's where I am now.
Short of idea.
Do you have any that may help me, please ?

Have you tried flashing through fastboot?

MS_UL PVT SHIP S-ON
Check that line again ! MS is not a M8 ! Post the info here from the command :
Fastboot getvar all
Post it but DELETE the SERIAL & IMEI before doing so !

Nothing wrong with your specs, you can flash the latest roms in the development section. Probably a user error. Wiped all before installing a new rom. What rom did you try, which TWRP are you using, what steps did you take EXACTLY !
Just saying you have the same problem isn't enough to work with at all !

There is no 4.16.401.13 RUU, you need a stock backup to restore !
1 - stock software, use a 4.16.401.13 or .10
http://forum.xda-developers.com/showthread.php?t=3086860
2 - no need to unroot because these backups are NOT rooted
2.1 - if you want future OTA you also need to flash back the stock recovery
3 - you can't LOCK the bootloader, only RELOCK it because your device is S-ON

Your firmware (hboot, radio, etc.) is old. You need to update it to run Lollipop ROMs. Sense Lollipop ROMs won't run properly with your KitKat firmware. CM12 won't work without hboot 3.19.
Easiest way to do so is restore the stock ROM for your current firmware, restore corresponding stock recovery, then OTA up to current Lollipop (which will also update firmware).
After that, you can install TWRP again, and flash the desired custom ROM, if you want.

So your issue is in fact not even remotely close to the OP's problem.
I hate it when folks say "I have the same problem", as from what I've seen, its almost never true. Even if the problem is similar, you should always provide as much detail as possible. Too many variables (numerous CIDs, firmware numbers, ROMs tried, exact steps that go you to this point, and much much more) to just say "I have the same problem".

Hello Redpoint73,
Thank you very much for your suggestion.
I did as you said.
And it sorted out the matter !!!
I am very happy.
Nevertheless, I found it a bit harder indeed cause I did not know the firmware originally installed on the phone (OS line blank), so I managed to find all the stock roms officially posted by the French phone operator Orange (correspunding to my CID), I extracted the recovery.img of each one and I flashed them one after another, flashing its correspunding recovery afterwards. Everytime I needed to install TWRP before a new stock rom flash. 3d trial was the right one and the phone was flashed like a charm. I went for official OTAs after that and now the phone runs great with the latest firmaware and rom.
Thnaks a lot every one !!!!
I have to say I found better help and attention here than anywhere else.
Thumbs up !

This is a known (and common) bug caused by older TWRP builds.
Nice work figuring it out yourself!

M8 starting up in Fastboot, won't load installed ROM

I've stuffed something up along the way and now my M8 seems to refuse to load any ROM I've installed on it. What's the best way to go about fixing this? It's unlocked with S-Off.

Flashing an RUU is a silver bullet for starting over, as an RUU formats all your device's partitions and flashes them with stock images.
You'll need to provide CID & MID or your current firmware version (i.e. 4.16.401.10) if you need help locating a compatible RUU.
Cheers

Need some more details to see why the phone won't boot into OS after flashing a ROM.
Is an OS number indicated on the bootloader screen? If so, what is it?
What version TWRP?
What ROMs have you tried?

I've tried flashing a few different RUUs and they all come out with an error 155. Googling it suggests I need to relock my bootloader but locking it and running the RUU again gives me the same error. I'm using SuperCID 11111111 and my MID is 0P6B70000. Currently on firmware 4.16.1540.8.

My OS number is 4.16.1540.8, I've tried TWRP 2.7.0.1, 2.8.7.0 and 3.0.0.0, roms I've tried include CM13, SkyDragon and a stock TWRP backup I found in another thread here.

Your MID and firmware number don't jive; and it can indicate something pretty dangerous (and possibly a radio bricked phone).
Need more info on what you've done.
Do fastboot getvar all, and post the output (delete serial number and IMEI before posting).
Was the phone new and stock (unmodified) when you got it; or did it have a previous owner?
Please list all the mods you have applied (s-off, changed CID, changed MID? etc.).

Ok, here's what getvar all reports:

I bought the phone second-hand, it was running a custom ROM (SkyDragon) with cid already set to 11111111 and I wanted to return it to stock. I got the Unlocked/Developer RUU from HTC's site but that didn't start up for me so I tried a bunch of stuff, fiddling with firmwares and unlocking/relocking bootloader and so on but in the end the RUU just hadn't downloaded properly. Once I managed to get the RUUs to run they've all come up with error 155 when they start the flash and flashing the rom.zip direct gives me an error (I forget if it's the same or different)
I've also tried restoring assorted TWRP backups, installing new roms and so on, directly flashing boot.img, things seem to flash ok but the phone just boots direct into fastboot.

Update: I'm not sure what went differently this time but I've installed the latest Cyanogenmod nightly and it's starting up as expected.
I'd like to get back to stock though. What's the best way to go about doing this? The phone was already modified when I got it so I'm not sure what it would've had on it when it was purchased originally.
Edit: A bit of googling suggests this is a Sprint handset (I dismissed this to begin with since I'm in Australia and didn't think it'd be an overseas handset, but ok) so I've flashed 6.20.651.3 firmware and am waiting for a matching RUU to download. Fingers crossed!
Edit again: All sorted now, thanks for your help!

Happy to see your sorted it out.
I agree it appears to be the Sprint version, based on the the MID (0P6B70000) and product name (m8_whl). While the MID can be modified, the product name is typically not (never seen a mod method for that - so the product name is very reliable).
That being said, I would strongly caution you moving forward, to not flash any firmware or RUU to this device except Sprint M8 firmware/RUU. Reason being, the partitioning on the Sprint phone is different from most other versions; and flashing another version's firmware can lead to a radio brick (phone boots, but nothing requiring the radio will work).

This is Sprint version, same as OP based on the model ID and product name. Although main version would indicate the Sprint Harmon Kardon version. RUU can be found at the bottom of the following webpage: http://www.htc.com/us/support/htc-one-m8-harman-kardon-edition-sprint/news/
The M8x designation on the back cover can't be trusted in this case. The back cover has been replaced to remove the "Sprint" logo branding. We've seen several phones like this (back cover replaced to remove evidence of branding) on the forum. You have to go by the getvar data.
Also, be sure to remove your IMEI and serial number from the getvar output. These are personal data, and should never be posted online.

To run a Marshmallow RUU, you need to fastboot flash its firmware.zip first.
1. flash 6.20.651.3 firmware.zip
2. run RUU
You should be able to find the firmware.zip in Sprint section
Or you try to find one version lower (lollipop) than 6.20.651.3 RUU, run it then do OTA to 6.20.651.3

To run a Marshmallow RUU, you need to fastboot flash its firmware.zip first.
1. flash 6.20.651.3 firmware.zip
2. run RUU

Just to confirm, if I get a lollipop version, do I still need to fastboot flash a firmware.zip?

FYI : i have tested on RUU exe. it came with FAIL 155, RUU zip as well it cant be done, i have this problem almost one week, i have tried it from stock recovery and it keep fail, ota downloaded but cant install reason coz have a modified rom, so frustated for this phone

Have you tried flashing it via bootloader? Zipped ruu not exe. Renaming ruu.zip to 0P6BIMG (at least that's what is the name on sprint m8) and flashing it inside hboot itself?

I think you are correct in your thinking, in that OP is trying to flash a Marshmallow RUU. In which case, they need to flash MM firmware, then they can RUU.
