Use twrp to sideload the rom. I think you go to Advance tab in TWRP and choose sideload rom and adb I think the command is "adb sideload <name of rom>".
I can't remember fully. I hope someonce can assist you and correct me if I'm wrong.

Thanks for the replay.
The problem is i'm on stock recovery. I got it back after updating the firmware.
Now i'm relocked and stuck with the stock recovery.
I thinks first i need to unlock and then flash the custom recovery.
But how to do it while i'm in bootloader and with no OS in place!!

When you are in bootloader, click on Fastboot. After you are in Fastboot USB mode (it will show that on the screen), unlock the bootloader using this tutorial:
http://www.redmondpie.com/how-to-unlock-htc-one-bootloader-tutorial/
After you are done with that, you'll need to download TWRP 2.5.0 and place it inside your fastboot folder on your computer, and then open a command prompt window from there (shift + right click and open command prompt window here) and then execute this command:
fastboot flash recovery recovery.img
Of course you replace recovery.img with whatever the name of your recovery is, in that case TWRP 2.5.0's zip file.

Thanks a lot.

Now how i can get my OS back to business.
Do i need to flash the stock rom or any rom? and how can i flash it!!

So, i think is better flashing a ruu, like the stock european ruu and, via Revone tool, flash a recovery
You're s-offed, you don't need unlock your bootloader

Thanks for the tip.
i'm only a littlle android guy. i hardly manage to get my S-OFF.
would you be so kind to show me on how to do that:angel:

Depends on what you are looking for. Are you trying to revert your device to stock status so you can receive OTA updates? Because that would mean flashing a RUU and relocking the bootloader, as mentioned above. However if you aren't interested in OTA updates (which we don't know when will be available) then go for the easier route, a custom ROM which you flash via TWRP recovery. After you go into TWRP, go to Advanced and choose ADB sideload and then slide to start, then use your computer to adb sideload rom.zip (of course rom.zip will be replaced by whichever ROM you want to sideload).
This is to set up ADB:
http://www.howtogeek.com/125769/how-to-install-and-use-abd-the-android-debug-bridge-utility/
The proper drivers for your PC to recognize the device in ADB mode are obtained by installing HTC Sync Manager.

He can use the adb push command too...

Ah okay. I am new to all of this so I don't have sufficient information, I was just sharing how I got to fix my device when I was in the same situation.

I used adb push zip file as below instruction:
C:\Android>adb devices
List of devices attached
FA35VW927790 recovery
C:\Android>adb push Android_Revolution_HD-One_9.4.zip /data/media/
3100 KB/s (1017950778 bytes in 320.621s)
C:\Android>adb reboot recovery
C:\Android>
I try to look for the zip file but did not find it?? any ideas

Still stuck at this point.
I tried to adb push it many times but still no success
:crying:
Please guys tell me if im doing something wrong or you have a better way of doing it.

The zip will be there somewhere, I command '/sdcard' instead of '/data/media'.
If you still can't find it just use
adb sideload Android_Revolution_HD-One_9.4.zip
Choose install zip from sideload in recovery and once it's finished transferring it will begin to install automatically so you won't have to look for the zip file

because you wiped your internal storage there is no file structure there, that's why you cant find the zip file.
You'll have to sideload your rom from twrp then boot up your phone which will create the needed directories.
1) update your android sdk. Sideload only works on certain versions of the sdk.
2) Place the rom you would like to flash in the same folder as fastboot and adb.( for you it looks like C:\Android\sdk\platform-tools
3) next from twrp under the advanced tab turn on adb sideload
4) issue the command adb sideload name of rom.zip
good luck

If you use /sdcard then it will work fine, I had the same issue

Victory at last :laugh:
My experience:
TWRP recovery
1.Tried to adb push /sdcard succeeded on this but failed to flash!!
2. Tried to adb sideload failed.
3. Flashed another recovery CWM.
4. adb sideload file.zip...........success
I don't why TWRP recovery was not responding correctly.
Any way got my phone back to life. and hopefully my experience could help people who made the same foolish mistake!!
Thanks to everybody who contributed to this post.

Maybe you had an earlier version of TWRP which had incompatibility issues with ADB. Anyway I'm glad you got through it. I sure hate being stuck like that as well.

[Q] new Recovery.img

Hi all,
My HTC ONE can not use ADB sideload with new recovery.img file (which has >8MB file size) only works with 7MB file (i has use the old file to send adb sideload) and i use ARHD v30. any fix ?

If you are using twrp, try "adb push file.zip /data/media/0"
Im not sure what you are trying to do, load a new recovery? You would do that from bootloader with "fastboot flash recovery recovery.img"

Hi an0ther,
I am running ARHD v22 with no problems. Then I try to install V30 in recovery mode - from zipfiles. After that, it only run a cicles in HTC boot logo and recovery mode. I start over again form 1st step to relock my HTC, flash recovery.img etc.
Now, my HTC only work with old recovery.img and ARHD v22. If i try 2 other recovery.img event with ARHD v22 is still not works.

I'm not sure exactly what is going on. We might have a language barrier here. You might have a corrupt Rom file. You said relock, not sure if you are talking about the bootloader which you don't need to do. Unless you are trying to flash stock ruu and you are s-on.

I am done. I have to flash the right firmware which support the new ARHD V30 (4.3) then every things seem to be okay now.

Problem installing Clockworkmod

hi guys! I'm new at this forum, so if i'm doing something wrong about rules and regulation, even if i've read them, correct me please! However, i just bough an At&T Atrix HD with stock 4.1.1 and i wanted to install a CM11; i obtained root privileges and unlocked the bootloader, and when i try to flash the clockwork recovery, apparently everything goes fine in fact i get no errors, but when i turn off the device and try to reboot in recovery it displays the "dead" droid with a red explanation mark. I've read in the cyanogen wiki that some firmwares during the reboot overwrite the custom recovery, is this the case? Which is the command or the procedure to reboot the cell in recovery then?
PS: I flash it through the command line by the PC, i got OSx and i tried with the clockwork posted in cyanogen wiki and the one posted here http://forum.xda-developers.com/showthread.php?t=2421418

Hi, first of all, did you installed the recovery with: fastboot flash recovery recovery.img right??
If you did so, you just need to turn off your phone, hold volume up button and power button and wait until it enters to recovery mode. From there you can flash a new ROM if you have it on your SD card or internal storage.

1. You're rooted so go to /system/etc and rename "install-recovery.sh" to "install-recovery.sh.bak"
2. Use Myth Tools to flash recovery (CWM or PhizTouch is included in the tool)
3. Check and Test

thanks to both of you guys!! i've solved with the solution in the second post, just deleting the "install-recovery.sh" script, i was going crazy!! i hope this post will help someone else!

Nope. You need to do it manually.
I tried to put that function into Myth Tools but it's impossible to do it via adb commands if the kernel is not enabled "insecure".
That's why I put a guide line in Myth Tools to remind user rename that file manually before flashing recovery.

Not necessarily. You don't HAVE to rename that file before flashing. The newer CWM's detect that file and will fix it for you. All you gotta do is enter recovery and exit it through the menu, it'll prompt about the file, and say yes to it. Problem solved. It's what I do along with flashing a root zip with every stock flash I do; haven't had a problem yet.
"Enter and exit CWM" is a lot easier to describe than renaming or deleting a file on the /system partition...less error prone too.

[LOLLIPOP 5.1][STOCK] Cherry Mobile One H940 Official Links

Here're the official links for Cherry Mobile One H940:
For fastboot flashable images:
Builds Available: LBY29G, LMY47O
Download: here
For OTAs:
Build: LBY29G -> LMY47O
Android Version: 5.1 (Beta) -> 5.1 Official
Download: here
Flashing Instructions:
A. Using ADB sideload (for recovery flashable update zips):
1.) Flash stock recovery.
2.) Boot to stock recovery.
3.) Perform up + power button to show menu.
4.) Select Apply update from ADB.
5.) Install ADB drivers if on Windows and not yet installed.
6.) Open cmd prompt.
7.) Change directory to where you downloaded the update zip.
8.) Issue cmd: adb sideload <update.zip filename>
9.) Wait until completed.
10.) Select reboot.
B. Using fastboot:
1.) Boot into bootloader.
2.) Flash image using fastboot flash <partition name> <image filename>.img command.
3.) Reboot using fastboot reboot command.
C. Using DD (for flashing images like system.img):
1.) Boot into custom recovery. (you could use fastboot boot custom-recovery.img so that you don't overwrite your existing one)
2.) Push image file to /sdcard using adb push command. (you might have to mount the sdcard partition before doing this)
3.) Open an ADB command shell.
4.) Go to /sdcard.
5.) Find the system partition by issuing a cat /proc/partitions command. It should be the one sized exactly 1GB (1,024,000 shown).
6.) Use dd if=/sdcard/<image filename>.img of=/dev/block/<name of partition> .
7.) Reboot either using custom recovery or just issuing an adb reboot after exiting from ADB command shell.

do you have another working file for LMY47O system.img? i'm getting a fastboot flash fail (chunk unkown) error. thanks

Reuploading now. Might be a bad upload from my end. Will post updated hashes later for the system.img.

No you don't need to relock the bootloader. You just need to flash stock boot partition. This is usually replaced when rooting.

Still, it should be foolproof. I already checked and double-checked the system image I uploaded and it's mountable in Linux so it should restore correctly like the previous LBY image. I can't think of any other reason aside from some sort of protection that would disallow flashing of the system image through both fastboot and dd.
*On second thought, I'm reupping the image. I just flashed it using dd on my device and it works perfectly.

success, was running a windows 7 virtual machine in OSX. it must have been a protection, you are right...ran it using OSX instead (stupid me, why i didn't use it in the first place for fastboot).
files are good to go thanks man

Need help in Flashing the Stock Recovery.
Hi Guys,
I need help in flashing the stock recovery.
I've used the ALL-IN-ONE TOOL to unlock my phone's bootloader, flash the PhilZ Touch Customer recovery and Root my CM1
[http://forum.xda-developers.com/cro.../tool-master-tool-unlock-bootloader-t2997696]
However I'm unsuccessful flashing the stock recovery from the ALL-IN-ONE TOOL so I can update my phone's software to Android 5.1.1.
Can I flash the stock recovery using one of the files here? If yes, can someone please teach me how.
Thanks in advance!

OTG
Hi,
Just a quick question, after flashing using this ROM, will CM One support OTG? Or do I need to root the phone first? Is there a way to add support for OTG?
Pardon me if this may not be much related to the topic.

3: Download TWRP
4: Download SuperSU and copy it to your phone's internal memory
5: Enable USB debugging and type "adb reboot-bootloader" from pc
6: Type: "fastboot boot twrp-3.1.1-0-alpine.img"
make sure you have twrp image in same folder as adb.
7: Wait for sometime you will boot into twrp recovery from there select install and select the SuperSU zip file

You should make sure you get a pristine backup at hand, or a RUU appropriate to your device. Otherwise you'll never be able toreturn to a full stock system.
On the U11 it is possible to boot TWRP from fastboot, without flashing it and thus without touching stock recovery. That way I've been able to flash Magisk what's coming with MagiskSU and the possibility to use some Modules. And all without altering the system or replacing stock recovery in the first place.

The guys method of using recovery to backup recovery will only work on Philz… Not twrp as it does not always backup stock recovery properly. The proper way to backup stock recovery is..
1. Root your phone, which can be done by towel root or by just booting a recovery like he said,
fastboot boot twrporwhatever.img, then flash supersu
2. Boot phone that has stock recovery
3. adb shell
4. su "watch your phone to grant root adb access if you haven't ever done it"
5. dd if=/dev/block/mmcblk0p43 of=/sdcard/recovery.img
6. This will put flashable recovery.img on your internal sd card. Copy this and save it for later
7. "fastboot flash recovery recovery.img" will get you back to stock recovery, "fastboot flash recovery twrporwhatever.img" to flash custom recovery.
Click to expand...
Click to collapse

If possible and a TWRP recovery is available one should boot to bootloader and try if the command fastboot boot name_of_twrp.img works. Make sure to NOT grant r/w at first boot and leave it ro. Now you can perform a backup of stock recovery, boot and system image (not system partition!) to obtain a pristine backup.
All else will alter system partitions md5 and the backup won't be pristine any longer. Due to block based OTA policy introduced by Google you won't be able to OTA without a pristine system image.

I have two questions.
1. If I fastboot to TWPR will it stay (flash for good) or after disconnecting my phone it will be gone ?
2. Can I flash Magisk instead of SuperSU ?

But in download mode there is no fastboot active ?! Until you installed the correct drivers

no "fastboot" (like a "one s", etc) on this phone. no fastboot usb
"fastboot" command work in "bootloader menu" and "download mode"
fastboot oem only in download mode

Hello. Please explain what I am doing wrong. I will download what is in points. I download this adb something, but it does not work. Nothing starts. Does not communicate with the phone. OCB. Could anyone write this guide so that he could understand and act?
