HTC one m8 won't accept any other rims

[okhughes]

Hi,
I have an M8 that I bought as a project to mess around with, bootloader was already unlocked, but was still S ON, It was already running a ROM that wasn't stock, but no big deal, went to flash Viper ROM and would only boot back into the bootloader - no splash screen.. I then tried the Android revolution HD with the same problem. I'm using the latest TWRP and doing the wipes before flashing the rom
CID is HTCCN701
MID is OP6B5000
Main is 4.29.1400.6
HBoot is 3.19.0.0000

Obviously a Chinese phone, so I S OFFed last night hoping that that was somehow stopping the flash.
My next step i'm thinking is to change the CID and MID and flash a corresponding firmware (Australian region) but am concerned if these rom flashes don't take then the firmware won't either.
just as a side note, flashed the M7 ARHD by accident and phone rebooted to splash screen and got stuck in a bootloop, but didn't boot straight to the bootloader, but when I flashed the correct version, booted straight to bootloader.
Did post this in a general Q&A, and got back recommendation that I super cid which I have done. Also flash WWE firmware, but I've still got reservations as I can't flash any other Rom at the moment, even though twrp says the flash is successful. I don't want to flash firmware and have it die completely if that doesn't take.
Does anyone have any advice?

And obviously you wasted the money that you spent to S-Off.
Something that I always see .. people paid money for S-Off but don't know what to do with it or why he needs it.

You can never change a phone variant with S-Off.

Your device is M8_TL ... you can't convert it to M8_UL or M8_UHL even with S-Off.
Same principle as you can't convert a Sprint device to Int'l GSM -

you can't convert a M8_WHL to M8_TL or M8_UL or M8_UHL or M8_WLV or M8_UL_CA

same goes

you can't convert a M8_TL (your device variant) to M8_WHL or M8_UL or M8_UHL or M8_WLV or M8_UL_CA

To install a custom ROM on your M8_TL .. you need to know whether the ROM support M8_TL or not. I don't personally see any of them ... most common is a ROM with support for M8_UL, M8_UHL, M8_WHL and M8_WLV in one zip.

Another note ... I don't advise to install any M8_UL firmware on your M8_TL .. you'll either totally brick the device or you'll brick the radio.

The best for you is google for your software version RUU .. mostly on Chinese site they have the RUU for this device.

Thanks for the advice, Will leave it as it is, it is running a custom Rom at the moment and is in working order.

Hello.

Not very knowledgeable here, so pardon my somewhat silly questions. I just bought 3 HTC M8 devices, with a view to upgrading to Marshmallow. They're for my mum and 2 younger siblings. I discovered I had the M8_UL, M8_TL and M8Q_UL.

I've been able to upgrade the M8Q_UL and M8_UL to marshmallow, the M8_TL has been the x factor. Can you please point me in the right direction?

I've done tons of research - that's how I was able to upgrade the other 2 - but there's very limited information on the M8_TL.

CID -11111111
HBOOT-3.19
RADIO-1.29.2145000121.12G
OS-6.12.401.4 (I did a firmware update before I found your post about not being able to convert the device, sorry)

Thanks.

I eventually worked out the TL variant is a Chinese version, unfortunately there was limited stuff available at the time I originally set about trying to flash roms, in the end, I left it with the custom rom it came with, as there was no others available, and no firmware updates, I wouldn't bother trying to do anything with it, but if you're planning to use, I'd root it and uninstall any suspicious app that's not needed (bloatware) as I didn't fully trust some of the Chinese apps not to pass data back, but if you've already updated firmware with an incompatible one, the phone may not work unless you put the original one back on.

I believe there are a lot of information on Chinese forum but not on others.
If you changed MID for M8_TL, then you need to change it back to original MID. If never change, then usually flashing RUU will work on SuperCID (if not, need to change CID too).

You can try the Marshmallow RUU 6.20.1400.1 to update your M8_TL
(only if your original firmware is x.xx.1400.x)

Thank you. I already downloaded this, but it fails with an 'image too large' error.

I tried both with and without an SD card. No dice. Any ideas?

relock bootloader. "Fastboot oem lock". Try again
