[Q] Go back to stock

[BerndM14]

Both times I converted to a lower version and did the update I had to flash the firmware twice to get radio(wifi data etc) to work properly. Just do the ota and flash firmware.

You're s-on yes? So you'll need to lock boot loader to flash, there is a guide by mike1986. Somewhere for HTC one m8.

Post 3 has OTA collection, you can extract the firmware.zip from inside the OTA.zip file. That'll give you the 2.x firmware, I don't know if there is a 3.x available for your device or not.

I Flashed a file named boot.emmc.win from inside the unzipped backup. I moved the file to my adb_fastboot folder and flashed it this way: fastboot flash recovery boot.emmc.win

Then I had trouble gaining access to custom recovery (TWRP) so I tried flashing the custom recovery again. I got in! Made a full wipe, chose "install", twrp > BACKUPS > Serialnumber > Backup.zip. But it failed!!!!! It was missing a md5 file???

I'm starting to regret all this root-mess

Like BerndM14 said:

Download any x.xx.401.x backup (HTC__001 will be fine).

After that, let your custom recovery (TWRP), and do this:
1) Place the nandroid backup unpacked on the sdcard of the phone in the right backup folder.
If you don't know your right backup folder:

TWRP\Backups\ or TWRP/Backups/serialnum/ (replace serialnum with your device's serial number. To have TWRP create the proper directory structure for you, just do a simple backup of just the boot partition and put the backup files in there)

2) Flash the boot.img or boot.emmc.win file from the nandroid backup with this command (fastboot mode):

fastboot flash boot boot.img

PS: Don't flash the boot.img with "fastboot flash recovery boot.img" command. That's why you had to flash TWRP again.

3) Access your custom recovery (TWRP)

4) Make a full wipe

5) Restore the nandroid backup and reboot

PS: Restore option is on TWRP > Restore. After access this, it will ask you to choose the folder that your have unzipped on the fisrt step (the one in the TWRP/Backups/serialnum/ folder).

6) Your phone now will be stock, BUT to receive OTA updates your ROM must be stock and your recovery must be stock. So, download a recovery that is with the same number of your downloaded backup (For example, if you download the x.xx.401.x backup, download the x.xx.401.x recovery too. If there is no exactly number for the recovery, download the one that start with the same number. For example, if you download x.xx.401.x backup you can download the recovery of x.xx.YY.Y version).

7) After you do the initial configurations of the stock ROM, access the fastboot again and flash the downloaded recovery with this command:

fastboot flash recovery recovery.emmc.win

That's it. Now with the stock ROM and the stock recovery, you can receive OTA updates (Settings>About>Softwares Updates).

I have downloaded that file, I presume that is the ota that I get notified about after I do the first one which causes my WiFi to stop working.
How do I go about extracting the firmware from the ota that I downloaded? Is there a way to manually install the ota as a whole?

I'll give it a try. But shouldn't I be S-OFF?? And shouldn't my bootloader be locked??

 

[RenBund88]

Success!!!

I'll give it a try. But shouldn't I be S-OFF?? And shouldn't my bootloader be locked??

I followed every single step from your guide! Actually I'm doing OTA's as we speak!!

I didn't flash Stock ROM though.. I believe it was already in the Nandroid Backup???

Should I relock my bootloader as well?? Would it make any difference in my future stock-world ?

Thanks A LOT, to all of you

A did this exactly steps with my HTC M8. The bootloader is unlocked and it is S-ON. This works flawless for me. My device get all OTA's updates and then I could install another ROM.

Yes, you didn't have to flash the ROM. I don't know what exaclty is flashed with the boot or boot.emmc.win image. The Nandroid Backup replaces every ROM file so, I think we can say that the stock ROM is alreadly in the backup.

I don't think that relock the bootloader will make any difference, since HTC made the bootloader unlock by it own site (www.htcdev.com). Maybe it makes difference for selling.

Li-nk don't work

here's the steps to get you back to stock
download this >NjZB8PHNylw5f3Y

while it's downloading go into TWRP and choose Backup
uncheck everything except boot ... do the backup

this will create a folder on your sdcard TWRP/BACKUPS/your_Serial_no/Todays date

when the download is complete extract it to the Todays date folder. Make sure it's just files in the folder and no folders

now boot back to TWRP and choose restore and restore the backup / make sure system and boot are checked.


you flash it the same as TWRP

fastboot flash recovery recovery.img
fastboot erase cache
fastboot reboot

your phone should now be back to stock and ready for OTA update

LI-NK dos'nt work!! can you re-post it

 

[nickrule1896]

Yes, the 4.4.4 ROM MUST have 3.28.xxx.x firmware in order to function properly. You're still on much older firmware which is why you have excessively long boot up times, wifi/data problems(Outdated radio) etc. In order for the ARHD 21.0 to work correctly you must be on the correct firmware(4.4.4 android version, 3.28.401.6/7 <<<If you're international version which you are). This has been the case for some time now, you can do an easy google search "htc one m8 xda ..." along with something like "slow boot up" etc and you'll see that all of them had the same problems, outdated firmware.

Which is why you'll have to go back to stock and do the OTA updates as it comes. If you were S-OFF you could have done it manually and flashed the firmware manually but since you're S-ON you can't do it. Flashing Radio firmware you'll need to either be a) S-OFF or b) Official HTC OTA.

Hey same problem here, just that i am on HTC_044. I am really confuse too with all these recovery and firmware stuff. I have a few questions so anyone please help!
1. So if i am S-Offed, i need not restore nandroid backup, flash stock recovery all that?
2.You mean i just need to flash the firmware.zip corresponding to mine right?
3. Does flashing a firmware wipe anything?
4. If I can just flash my firmware, how do i know what is the current firmware i have so that i can choose which firmware OTA to download?

Hi, after reading many pages i'm confused....
I'm S-ON.
I need to return to stock from ViperOne 1.8.0 to recive the OTA.
Before change ROM i made (just after the root) a TWRP backup of stock ROM (full).
Is sufficent to restore this backup from TWRP or need other actions?

Thanks

Alex

You need to restore stock recovery as well. If you don't, the OTA will look for stock recovery to install the update, fail to find it and OTA will fail to install. You will probably also be stuck in a bootloop (as the phone keeps trying to boot into stock recovery).

Since its kind of a "trick" to use custom recovery to backup stock recovery, you probably haven't done so, and need to look at the following thread to see if your stock recovery is posted:

Ok..thanks but i have also another doubt:
The boot.img must be flashed via PC (fastboot) or via TWRP (and so on every time tell flash in explanation in post 26).
Thanks
Alex
P.s.: answer myself...following post 26 and use fastboot with PC when needed...perfectly back to stock, retrive OTA's and now on ViperOne 3.0.1. :good:
...sorry a bit noob
