Sprint M8 Stock Roms

[Fuhcue]

Hi, I made this post in the Sprint section a few days ago, but figured I'd post here as well to see if maybe this section has more traffic. If that's not allowed, I apologize in advance.

https://forum.xda-developers.com/sprint-htc-one-m8/help/stock-roms-t3669676

Basically, I'm looking for a stock rom for Sprint that would work with 1.54.651.8 firmware. All the links I can find on the forums seem to be dead.

Alternatively, a nandroid backup or way to extract the rom from the 1.54.651.8 RUU I do have (but won't successfully flash for whatever reason)

Any help would be appreciated. Thanks!

A custom ROM would need to support the Sprint M8, and be based on 4.4.2. Most any newer (newer than KitKat) ROMs will suffer major incompatibility with your ancient firmware, including extreme long boot time or no boot, and broken WiFi.

Suggest stocking with updating the firmware. Is the device s-on or s-off?

Problems with the RUU while "sending" are usually on the PC side. Try to re-install HTC drivers, try another USB port (USB 2.0 works best), and try another cable. Or even try another PC if possible.

Yeah I was able to find one custom 4.4.4 ROM (It was labelled 4.4.2, but it works so I guess it's close enough). There are just a few issues with it and I've always been more of a stock person anyway so I'd rather use a stock rom if I have the option.

As far as updating firmware, I am S-ON - I only originally rooted for a wifi hotspot app, so I didn't have a need to go S-OFF.

I guess it wouldn't hurt to give the RUUs a shot on a different computer. I'll just have to talk a friend into letting me install the drivers and giving it a go. One thing I'm not sure about - is it safe to go straight to the lastest RUU on HTC's site? I was willing to try it back when I had no rom at all, but now that I have a custom rom that mostly works, I'd rather not totally crap the bed.

You can "skip" RUUs, and go the latest. However, you may (probably) need to update to the Marshmallow firmware anyway, before you can RUU. There is a strange limitation on most US version M8, where the RUU will fail with Error 155, if you try to go to Marshmallow from any former version (be it Kitkat or Lollipop) without first updating the firmware.

So the steps would be:

1) Relock bootloader
2) Flash to Marshmallow signed firmware (Sprint), in fastbootRUU mode
3) RUU to Marshmallow
4) Unlock bootloader again
5) Flash TWRP, root, and do whatever mods you want

Seeing as RUU will also wipe the phone. All this might be more than you want to do, if you are fairly happy with the phone as it is.

I don't so much mind the wipe, but I am a bit nervous about updating the firmware since that sounds like it could leave me in limbo if the RUU still didn't want to work for whatever reason. I guess I'll search around for where I can get that firmware and the procedure of how to do it and see how comfortable I feel with it in case I go that route.

If I knew for sure that it would all go through, I'd be fine with the reset. But that seems to take the attractive part of the RUU away in that it's no longer an "all in one" or one step process. (Not counting unlocking/relocking the bootloader since that's a quick and easy thing).

The firmware is posted in the same thread as the RUUs. And instructions on how to flash, as well.

You can also opt for the Lollipop RUU (does not require flashing the firmware first). While not the latest, it's obviously more updated than what you presently have. And most of the current MM ROMs should work with LP firmware. There isn't much difference in the firmware it seems, for LP versus MM. Much different from KK to LP, which causes the problems I mentioned earlier (if you try to run KK firmware with LP or MM ROMs).

For maximum compatibility, matching the firmware is usually best. But I was running LP firmware with MM ROMs for a while (was simply to lazy to flash the MM firmware or RUU).

 

[Fuhcue]

Ok so it sounds like the easiest option for me at this point is to grab a Lollipop RUU and try to flash it from a new computer with a fresh install of all the drivers. That way, at least if it fails to recognize my phone like the newest one did, I'll still be where I currently am with the stock (though outdated) firmware and custom rom.

Otherwise, I'll keep my fingers crossed that someone stumbles across this thread that has a meticulous archive of all old stock Sprint roms

Thanks so much for all your help and answering my questions so quickly. Much appreciated.

Hi

This is Sudheer from INDIA

i got Sprint HTC one M8 Harman Kardon from my friend.

after jail break it's supported Indian GSM sims there after only outgoing calls are working incoming calls are not working.

after so much of web search i unlock boot loader using HTC All in one and i enter into twrp wipe all system,cache and data. now its' hang on startup white screen not booting. yesterday i am trying to install os from following reference.

forum.xda-developers.com/showthread.php?t=2729173

finally i got 155 error Unsupported RUU. Please help me to come out with step by step guide because i am new for installing android phones.

"Jail break" is a term specific to only iPhones. There is not such thing as "jail break" on an Android device. I assume you mean s-off, or some other mod? I can only guess, if you don't use the specific and proper terminology.

All in one Toolkit is obsolete, you shouldn't be using it. It contains a very old version of TWRP which will cause problems for many folks.

System partition is the OS/ROM. Should be obvious, that wiping the system partition results in no OS. Can't boot to an OS that isn't there any more. If you didn't know what the result would be from wiping a partition, you should be touching it in the first place!!!! Those options are listed under "Advanced" for a reason. If you aren't an advanced user, don't mess with them, unless you are following directions form an experienced user, or know what the result is going to be.

Not enough info to know why the RUU failed. You linked a post with multiple RUUs, so we don't know which one you tried. We also don't know your current phone configuration.

Which version number RUU did you try? For HK version, you typically will need to flash the one that contains the digits "654". The RUU with digits "651" is for non-HK Sprint version. Assuming CID/MID has not been modified (which we don't know, if you don't provide more info).

Post specific info about your phone. Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

If the phone is s-on, you need to lock it in order to RUU. I don't know if you are s-on of s--off.

You can't run a lower number (downgrade) RUU unless you have s-off. Again, I don't know what version number RUU you tried, your current version number on the phone, or whether you are s-on or s-off.

Hi Sir,

Thank you for replying. Sim Unlocked from mobile store. actually I also don't know witch method they are using to unlock. After unlocking network signals showing in GSM mode. When I am changing to LTE mode again signals disappeared. In GSM mode incoming calls are not working. SMS both incoming and outgoing working fine.

I tried to change CID and s-off but it's not working.

TWRP I used version v2.7.0.2 these recovery installed from all in one twrp (sprint). when i come back in to bootloader it will asking No OS installed are you sure you wish to reboot?

My mobile model is HTC one M8 HK (831C) Sprint Internal storage is 32GB.

I download and used to flash following files.
1. signed_6.20.654.3_firmware.zip
2.RUU_M8_WHL_M60_SENSE70_SPCS_MR_Sprint_WWE_Harman_6.20.654.3.exe
3.0P6BIMG_Sprint_HTC_One_M8_Harman_6.20.654.3_RUU.zip

What was I do is
First Re-locked bootloader using with all in one and rename firmware as 0P6BIMG.ZIP then flash from SD Card Installed Successfully. Bootloader also showing OS version 6.20.654.3
Next using exe file "RUU_M8_WHL_M60_SENSE70_SPCS_MR_Sprint_WWE_Harman_6.20.654.3.exe" everything going well when the process bar reaching to 100% then it's showing error 155. I Checked the error guide provide by exe file there Unsupported RUU please try again with supported RUU.
Next using with ZIP file "0P6BIMG_Sprint_HTC_One_M8_Harman_6.20.654.3_RUU.zip" flash from SD Card it will showing not enough memory but internal is full empty.

LTE is difficult (maybe impossible) to get working in cases where the device is not intended for your region/carrier (which I assume is the case, that you are not located in US, on the Sprint carrier). GSM should work (as you indicated) as well as 3G (HSPA) provided that your carrier uses a band(s) supported by the Sprint version M8

I tried to change CID and s-off but it's not working. I don't know what that means "it's not working". Most folks who say they have trouble with getting s-off, are trying the hopeless waste of time, which is trying to usethe long obsolete "free" s-off method of firewater. It's never going to work.
Also, you should also be careful here, when changing CID. Only use a Sprint CID, or SuperCID with a Sprint firmware/RUU. Trying to use any other firmware or RUU will result in a radio brick (possibly permanent).

TWRP I used version v2.7.0.2 these recovery installed from all in one twrp (sprint). when i come back in to bootloader it will asking No OS installed are you sure you wish to reboot? That version is too old (over 4 years) and you should have used current TWRP. This was probably caused by using the toolkit (which I mentioned is not advised anymore). Old versions of TWRP was not compatible with Sprint M8 (it had it's own "CDMA" version TWRP) and it probably caused the wrong partition to be overwritten.

What was I do is
First Re-locked bootloader using with all in one and rename firmware as 0P6BIMG.ZIP then flash from SD Card Installed Successfully. Bootloader also showing OS version 6.20.654.3 Try flashing firmware again, the number should show up in getvar all (below) under "version-main". Flashing firmware twice is usually a good idea.
Next using exe file "RUU_M8_WHL_M60_SENSE70_SPCS_MR_Sprint_WWE_Harman_6.20.654.3.exe" everything going well when the process bar reaching to 100% then it's showing error 155. I Checked the error guide provide by exe file there Unsupported RUU please try again with supported RUU.
Error 155 is common, if flashing a US Marshmallow RUU, without being on the matching firmware. Flashing firmware again, as indicated above, may solve it.
Next using with ZIP file "0P6BIMG_Sprint_HTC_One_M8_Harman_6.20.654.3_RUU.zip" flash from SD Card it will showing not enough memory but internal is full empty.
