[Q] HTC ONE Flashboot boot recovery (no flashing) - One (M7) Q&A, Help & Troubleshooting

Hi all.
On my HTC one hboot 1.44.000, I can run i ADB
fastboot boot boot boot.img
To boot on a custom recovery image without actually flashing the image.
On newer HTC one hboot 1.55.000 this has been disabled.
Does anyone know of any workaround to this problem?
Its a bit of a pain to do the initial backup of the stock recovery, rom and boot when you have to overwrite the stock recovery to do so.
Can the stock recovery be backed up to an img file from the ADB prompt, with stock recovery still loaded somehow?
In fact its a classic CATCH 22
I know you can extract the stock recovery later on from a the latest OAT update, but it would just be a lot more simple, if all you what is root, to boot on the image without flashing, install the super user app, then restore all the needed HTC specific apps you lose when unlocking and then you are back to stock with root.
Does anyone know the exact location of the OAT from where you can extract the stock boot and recovery from firmware.zip, and is this OAT deleted after it has been run, or if its still available to grab later one?
Since the device is not rooted yet, its not possible to check the \cashe folder for the OAT file before you rooted it.
What if its not there? How will you find the original stock recovery that fits your current system, any new OAT may have a different one, that mayl not work.
Again a CATCH 22
Why does HTC support unlocking the bootloader, and then limits it use, not allowing to boot on a recovery without flashing it ?

Afaik this is no longer possible to use remote recovery booting, htc disabled it.

There is many stock recoveries uploaded here if you can't find yours, then just request it and someone will probably upload it.

Incredible S will NOT accept other rom

I am trying to get rid of the CM7.1 on my Incredible S. I have fastboot on my Ubuntu machine and all the android libraries necessary. I tried a lot of commands from fastboot a couple of days ago but nothing happened. Miui got stuck on boot screen, CM7.2 also did the same. I want to wipe my phone. Delete everything. I am sick of the CM7.1 it is old.
My bootloader says this:
***UNLOCKED***
VIVO .. S-ON
HBOOT-2.00.0000
RADIO-3822.10.08.28_M
I want a step by step way to wipe my phone and install the STOCK ROM (but keeping my root), and using Ubuntu. I have been through dozens of tutorials, my phone wont wipe.
OFFICIAL ROMS:
http://www.filefactory.com/f/e45d6fe3dcf51228/
question: which one do I download (which one is the latest) and why do they have 100mb + difference? thanks a lot!
I need your help before I smash the phone on the wall
Since you're s-on still and unlocked, have you flashed the boot.img from the roms are flashed? Its required after a new rom/kernel flash in order to get the rom booting.
Why do I have to flash the boot.img? I download the *.zip file and flash the whole zip file using ROM manager. That should be enough

With s on you still have to fast boot flash boot.img to get the phone booting
Search how to do it, you probably did it when you flashed CM7

With the unlocked bootloader, the boot partition only gets mounted as ReadOnly when in Recovery mode, thus when you flash a ROM in recovery mode, the boot.img file does not get written to your phone.
You manually have to flash the boot.img while in FASTBOOT USB mode using the command:
fastboot flash boot [boot.img file]
Also, you stated that you want to install a stock ROM but keep your root. Here are some things to keep in mind:
1. In order to flash an official HTC stock RUU, you must relock your bootloader. If you attempt to flash a RUU on an unlocked bootloader, you will get a 155 error.
2. Depending on which stock RUU you choose to flash, that particular bootloader may or may not be unlockable.
In the Development section there are several IncS stock, rooted ROMs that were built from official RUUs. I would recommend you give those a try. You may also want to look at mike1986's ARHD ROM which is based on the IncS ICS ROM.

[Q] Can you just boot twrp recovery?

All,
I'm coming from a nexus environment where I've been able to do fastboot boot twrp-2.6.3.1-ghost-4.4.img rather than fastboot flash recovery twrp-2.6.3.1-ghost-4.4.img since I'm hoping to keep the stock recovery while installing supersu. It complains about "(bootloader) Command restricted" with the MotoX even though my bootloader is unlocked. Is this typical of Moto devices? Do I actually need to flash twrp, then supersu and then the stock recovery if that's the final result I want? FWIW, I want SU on it but I'd like to also receive future OTA updates w/o too much dorking around of at all possible.
thanks peterb
Are you using mfastboot or just regular fastboot?
I fastboot twrp no problem. I did however mfastboot the system.img . But to answer your question twrp will ask you if you want to root when you go to reboot.
Fastboot flash recovery twrp 2.6.3.1-ghost-4.4.img is the command, when you flash do not reboot the device to the system but boot into recovery instead, you should be good to go and twrp should ask if you wish to root, if not just download the flashable supersu zip
Sent on my Moto X
I understand that you should flash if you want to have TWRP installed on your phone but that's not what I want. I'd like to just boot into TWRP, install the SuperSU.zip and then boot back up as normal leaving the stock recovery in place so that I will continue to get OTA updates. I get that this is likely not the norm but it's what I did with my N4 to get SuperSu so that I could update boot.prop for flashing a hybrid radio. Doing this made it easier to get the phone back to OTA ready w/o having to flash the stock recovery back.
I found a couple of posts in the N4 where the fastboot command failed and you needed to start using the "-c" command. I was wondering if this was the problem I was running into. The argument for -c is a bit cryptic so I worry that the one I found is likely N4 specific:
fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img
Basically what I'm wondering is if anyone has been able to just boot into TWRP w/o actually flashing it to the recovery partition.
If this is not possible then I'll flash TWRP, root and then flash the stock recovery back on since I did get the stock 4.4 image from Motorola.
thanks peterb

Interested in this as well, for booting kernels. Device support has been hit-or-miss for me in the past.
And folks, he's asking about fastboot's ability to launch an image _without_ flashing. This is a somewhat esoteric/advanced use.
I'm interested in this too even though I have a locked Moto X.
I didn't know this was possible, huh. As for our device, it'll probably help if we can figure out what that -c command means.

If I'm remembering right, google took the ability to boot a recovery without loading one away in 4.2. We tried to do this on the HTC 1 Google edition when we pulled its partitions to make a system dump. It failed.
OTA fails when the device is rooted, even if you have the stock recovery.
The OTA zip checks the system partition. If there is any single modification, it fails.
you can just:
- flash twrp to recovery partition
- reboot into recovery
- install supersu
- reboot into fastboot
- flash stock recovery
- reboot to system
you have installed supersu and still have stock recovery -> you can take OTAs
edit: i just read that even with stock recovery, if u are rooted the ota won't work
Yea, this is the other way to do it. It's just a bummer if one can't use the flexibility to just boot into recovery. Note that I still seem to be able to boot into custom recovery on my Nexus 4 that's running KitKat. I'm curious about the comment about not getting an OTA with su installed. I know that with a modified build.prop and radio, the N4 wouldn't update but I could adb sideload successfully once I put build.prop back and the stock radio on. I figured the OTA would just unroot and then I'd have to do the process again.
Anyway, this was my plan B, just would have preferred to boot recovery.

I am interested in this as well. How do we get a copy of the stock recovery to reflash?
Also, I have had rooted stock and custom recoveries and have received OTA's before (but they were on Nexus devices).

you can take it from the the file used in rsdlite, according to you fw version
The only reason I want the stock recovery is because I think you can't remotely lock or erase your device on a custom recovery. Does anyone know anything to the contrary? Thanks.

Fastboot Boot Recovery.IMG not Working after Update

I have been using "fastboot boot recovery.img" to load into TWRP after OTA updates to load SuperSU as I am only rooted using the stock ROM. However, after this recent update (2.16.651.4) that includes the WiFi Calling and Android 4.4.3, when I run the command it just causes the phone to reboot. It does not reboot into TWRP, which is my recovery.img file.
I found a Nexus thread talking about having to add a kernel command line for the Nexus after a certain version of hboot, so I am not sure if it is related.
Does anyone know how to fastboot boot now with the latest update? I would like to avoid replacing my stock recovery with TWRP and just continue to boot into it. Alternatively, is there any other way to install supersu?
Thank you,
Ben

As a quick work around flash twrp onto the device, once done with it then flash the factory recovery back, Also check to make sure your bootloader didn't relock after update.

Thank you for the reply. I thought about taking that approach, but I was really hoping someone would have an answer on why the procedure wasn't working now. My bootloader is still unlocked.
I found this as an approach someone did on the Nexus 4 for a similar issue:
fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img
Thoughts?
nfinitefx45:
I did just now flash TWRP into recovery, loaded SuperSU, and then flashed your recovery.img back to the phone. So thank you very much for the recovery.img.
I'd still like to know if fastboot boot can still work, and also if there is a way in the future I can get my own recovery.img (possibly back it up before taking an OTA)?

not sure about the fastboot issue, but to backup your recovery any time just go to adb and type the following
adb shell
su
dd if=/dev/block/mmcblk0p43 of=/sdcard2/recovery.img
this will copy your recovery to the external sdcard
Thank you for those steps. I do not have an external SD card installed, so I modified it to store the recovery.img on sdcard instead.
Now I can always fastboot flash twrp and then back to stock recovery.
Thank you again!

You would need root to do this. Not being able to use "fastboot boot" you would just be backing up the flashed recovery. Possibly towel root temp root, but I would assume it has been patched in newest update.
So I am S-On with a non-HK M8
I was on stock rooted 4.4.2 and I flashed the stock recovery and took the OTA
Now I am on 4.4.3 and still have SuperSU installed (not rooted)
Everything is working fine, but when I try to boot to recovery i get the red triangle with the !

That's the stock recovery. Did you ever flash a custom recovery back on after the OTA?

Yes, after the OTA, just flash TWRP back through fastboot and then re-flash SuperSU to get root back.

What's the output in the terminal when you fastboot flash recovery?
rooting problem
It doesn't show any error as such.
In the command window it shows successful.
But when I click on recovery it reboots back to fast boot.
Like for a second it shows the screen which reads 'this build is only for developers'
But then instead of opening Twrp it reboots back to fast boot.

Trying to get back to stock rom

Hello,
Tried rooting my phone with no prior experience. Worked, but eventually I got to where the phone wouldn't boot past splash screen (logo came up, then screen went black while backlight is on and didn't respond to stimuli until battery was removed). Possibly resulted from a build.prop file problem. Did get into boot though, so I fixed that problem by installing a cyanogen rom from a zip file using twrp recovery. I didn't want a custom mod though since I'm used to the look and feel of the 4.0.3 ICS I had, and the cyanogen doesn't seem to have google play so I can't even download anything (original purpose of rooting was to get incompatible apps by spoofing via build.prop file). Currently trying to get back to stock. Unfortunately I didn't make a nandroid backup of the system before the problem occurred, hence I have no backup to flash.
What I tried:
1. Use the official HTC 4.0.3 RUU .exe to upload to the phone. Unfortunately HTC Sync doesn't see this phone, even though I have the correct drivers installed.
2. Attempted to use twrp recovery to install the rom.zip extracted from the RUU directly, the same way I successfully installed the cyanogenmod rom. Failed, claiming it's unable to open zip. The .zip file was checked for integrity and returned by an archiver app.
3. Tried to use these commands from the cmd with phone connected to install the .zip from fastboot:
fastboot erase cache
fastboot oem rebootRuu
fastboot flash zip rom.zip (rom.zip being the functional file of the stock rom)
Failed, saying it's not allowed. Tried it with both locked and unlocked bootloader, no difference.
4. Unzipped the file and tried to flash the system.img file directly, but that failed with a "data length is too large" error.
5. My recovery being twrp 2.1.1, tried looking for altenatives. Can't find any links to download the WCX recovery, but I found several for newer twrp versions, including 2.3.1.0 and 2.6.3.0 which I tried downloading flashing. After flashing the phone got stuck at the cyanogenmod loading logo and wouldn't boot further, and the recovery itself didn't work, just showed the HTC splash, turned black, then booted again normally, getting stuck at the cyanogen logo. Same thing for the 2.6.3.0 version, so I reflashed the original 2.1.1, at which point I can get into recovery but the phone is still stuck at the cyanogenmod during normal boot. At this point I installed the original cyanogenmod .zip from recovery and now at least the phone boots up normally. Still need to get stock back somehow.
Out of ideas and exhausted from this. Any help would be appreciated. Perhaps anyone has a working stock 4.0.3 rom for the Vivid, nandroid backup, etc., or any other ideas. Thanks for reading.
Oh crap...
OK... First... Stock rom can be found in development... Most of the roms there are stock... Read the OP... It'll tell you...
Second... You should use TWRP 2.5.3.0 or something like that I forget...
Third... When you tried the ruu... Did you relock your bootloader...
Side note... Could you get your phone to show up with 'fastboot devices'

When to flash new boot.img?

so.. simple question but I'm not sure of the answer..
I unlocked my boot loader and flashed my HTC with cyanogenmod and the relevant boot.img that came with it. now I've reinstalled back to android revolution and the sense os to be able to properly back up my contacts and photos without requiring HTC sync manager...however when I went back to android revolution Rom.. I didn't 're flash my boot.img..
when is it actually necessary to flash a new boot.img when changing roms?
also.. could anyone clarify for me... I'm currently s-on so boot.img can only be flashed through fastboot correct?
and if I was s-off.. when I install a custom rom it'll auto install the boot.img yes?
thanks
Owen

/boot isn't protected on the M7 so you don't have to flash the boot.img after flashing a rom, its flashed at the same time the rom is flashed from recovery. Won't hurt if you flash it again but its not necessary. If you want to manually flash the boot.img you can do it from fastboot or from twrp recovery. There is an option from twrp to flash .img files to your /boot or /recovery partitions. So yes you can flash boot and recovery from recovery. In both cases, S-OFF isn't required, unlike other HTC phones.
