Yes, I've downloaded the correct backup and recovery. When I try to flash the backup, it fails. I have tried about 4 different types of stock roms that should be compatible. Fail, fail, and more fail.
I flashed my HTC One M8 with a lollipop rom, and it messed up my Wifi. It doesnt work anymore. I've tried multiple roms and it works on none of them. I have tried flashing a stock backup and stock recovery so I can update my firmware completely via t-mobile, but the backup will not flash. Keeps saying failed with no error message.
Please help me. I've been trying to fix this on my own for days and it is really boggin' me down.
I'm on twrp 2.8.1.0
Firmware version 1.57.531.7
CID T-MOB010
TL;DR: I CAN'T FLASH A STOCK ROM SO I CAN UPDATE MY FIRMWARE! TWRP SAYS FAILED!
You don't actually flash the backup, you restore it.
Are you talking about a stock backup you've downloaded from a thread in here ?
If so I hope you understood the instructions as you need to extract it and place it in the twrp/backup/****** directory where you made your first backup.
Can you boot to a system at all?
Backup stock recovery for future OTA updates?
Hello,
I am currently on lollipop 5.0.1. I am looking to root the device and install TWRP as my go to recovery. I have being advised to backup my stock recovery so I am able to go back and update via OTA in the future.
I am unsure what the process is to backup stock recovery, any help would be appreciated.
Thanks in advance!
Your stock recovery will be in the next update. When being notified you download it but don't install it yet, take out the recovery.img from the ota.zip and flash it before you actually install the full ota.
No need to back it up now.
as an alternative to the above (which works just fine btw)
on the M8, you can boot into TWRP instead of flashing it
Code:
fastboot boot <name of twrp>.img
that will get you to twrp recovery, while the stock recovery is still on the phone, from there you can do a nandroid backup
Hello,
I have rooted my HTC One m8(No S-OFF). It also has TWRP and it's on Android 5.0.1/HTC Sense 6
I googled and read about reverting to stock recovery and then doing an OTA upgrade of the OS. But I'd rather not go back to stock and then TWRP back again.
Is there any way or instructional to follow that can enable me to update to Android 6 whilst keeping TWRP and my root settings on.
Any help is appreciated
My experience, is that Marshmallow ROMs work fine on Lollipop firmware. I've been doing so since December, for no better reason than I've been too lazy to update my firmware.
So that means you should be able to just restore the proper Marshmallow TWRP backup for your version, and just run that without updating anything else. Although, be sure to leave yourself an escape plan, just in case it doesn't work (either your own LP backup, or be prepared to use one from the collection).
However, for best compatibility, you should really update your firmware. And doing so, either by flashing stock firmware, OTA, or RUU by "official" means (and official/signed means are what you need to use, since you are s-on) will by definition wipe out TWRP.
But honestly, flashing TWRP back to the phone is easy. You just download the .img file to your computer, than flash with a single fastboot command, with the phone connected. This is actually a fast and simple process, when compared to the other stuff you are talking about doing (restoring stock backup and recovery, OTA update).
Plus, since you are updating to Marshmallow, you'll also want to update to TWRP 3.0.2 anyway.

Thanks redpoint73.
My chief motivation behind moving to Android 6 is a sound problem I've been having lately. I installed the AcousticX sound mod but when I listen to audiobooks, I hear a clipping sound sometimes.
The developer over @ AcousticX suggested a few things and one of which was making the switch to marshmallow.

From some reading and your suggestions, I gathered the right way to go about this is, is to flash stock recovery(overriding twrp). Do an OTA upgrade(1.6 gb download/install) and afterwards reinstall TWRP and whatever else was previously done.
Am I correct in surmising this?
Thanks

Not only the stock recovery, but you also need to restore the unrooted TWRP backup (never rooted ROM, "unrooting" doesn't work). Since having root will prevent OTA.
The full process is described here: http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
The other option, depending on what M8 version you have, may be to RUU to Marshmallow. That allows you skip a lot of the steps needed in the previous method (restoring a never rooted TWRP backup, restoring stock recovery, OTA updated) but adds a couple other steps (relock bootloader to RUU, unlock it again after RUU to flash TWRP); plus the RUU will wipe all user data on the device.
So its a judgment call for you (if your version has RUU) what path is preferred.
I finally managed to find out where my phone downloaded the Sprint Nougat OTA file, and copied it to my SDcard.
My phone is a Sprint HTC 10. The bootloader is unlocked and my recovery is TWRP, but other than that I am stock and unrooted.
Everyone says you need to be on stock everything to install an OTA update (though I had no issues installing previous OTA updates directly, but all of those were small), so I was reading up on flashing stock recovery.... but several people commented that flashing a stock recovery on their phone wiped it. I really don't want to take that risk, and with TWRP I can make a backup of my entire phone. So I wanted to know, if flashing an OTA update fails from TWRP, could that brick my phone bad enough that I wouldn't be able to flash the TWRP backup to restore it? Or can I recover as long as I can boot into... well, recovery. Would the OTA update overwrite the recovery too? Especially if I try to install it from within that recovery?
I was told to extract the "update.zip" file from the OTA.... but there is none in there, is the OTA zip file itself what they meant by "update.zip"?
flashing an ota with twrp won't work...at least it won't update the firmware bits.
So I found my old M83 the other day. It's running:
S-ON, UNLOCKED BOOTLOADER (NOW RELOCKED) ON TMOBILE.
I decided to try and flash the latest firmware via the sd card method, didn't work. Then tried flashing the firmware via fastboot. Fastboot didn't work either.
Now the phone only boots to the bootloader/hboot screen.
Any attempt at trying to flash firmware, or a recover, customer or otherwise fails.
I'm really hoping I can find a tmobile ruu zip to bring it back to life, however I can't seem to find a tmobile ruu zip anywhere anymore. I don't have a PC so downloading the *exe files doesn't do me much good.
Is there anyone that can please offer some assistance?
Much appreciated in advance!
What I did was to use TWRP and restore my original copy of the ROM (hopefully you still have that), if not you will need to find a TWRP backup of the ROM for the version of firmware you have and then restore the recovery for that same version (it get rid of TWRP). Then let the OTA fix update your phone. This is the route I took. Since Android 6 (MM) is the last release once you get to that stock, you can then replace the recovery (you could backup the recovery also) with TWRP, take a backup and then root or flash a new ROM.
Good luck
