HTC Desire HD won't boot after flash

Hello!
I have a big problem.
I might have bricked the device however the things what i can do are the following:
- Boot into recovery (clockworkmod)
- start a usb data connection with a computer (clockworkmod)
- input of the ADB commands through terminal running in the computer
What i did?
Flashed the memory with a Cyanogenmod 6.3 according to official guideline:
http://wiki.cyanogenmod.com/index.php?title=HTC_Desire_HD:_Full_Update_Guide
and took note and used most procedures from there actually:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2
Didn't do the engineering hboot.
Everything was working. I got cyanogenmod working.
Then after a while i tried to restore a backup which i had from original HTC configuration which was actually just before i did the cyanogenmod flash with clockworkmod.
So the backup was from the time i already unlocked the phone from locks and had root access.
So again the restore function worked and everything was back to normal.
How i managed to half brick the device?
Yesterday i wanted to put cyanogenmod back to my phone and then the s hit happened.
I admit that i didn't check whether the locks were off i just thought that these should have been off because backup soft was from time i had phone unlocked.
Anyway to cut the long story short - after flashing the memory with cyanogenmod with the help of rom manager the phone didn't boot anymore.
I tried all the options from clockworkmod flash and format and upgrade straight from sd card a new cyanogenmod but nothing worked. Again the white HTC screen and connection through a usb cable.
So probably i have the s-off and who knows what else.
I dont have a root access anymore as well because i already tried it through the terminal. It doesn't recognize the su command.
Question is, how can i put the cyanogenmod back on by only using clockworkmod recovery and working ADB connection through usb link?
Probably have to just get the locks off but the original instructions say i have to have terminal emulator running in phone but i only have clockworkmod recovery soft running at best.
S hit, again very long story, but hope someone can help me!
Cheers!

I had a similar problem yesterday, after flashing ClockwordkMod Recovery to version 3.0.0.5 (it said it had an update) and trying to reinstall CyanoGenmod 6.3 my phone would no longer boot, it got stuck in the white HTC Logo screen.
I'm not really an expert on this stuff, but I managed to "recover" my device by downgrading it again to 1.32.405.6 using this thread: http://forum.xda-developers.com/showthread.php?t=905003. First I had tried to recover a previously backed-up ROM, but that did not work.
I had to put the stock 1.32 PD98IMG.zip file on my SD card using ClockwordMod Recovery (since I could no longer boot), I'm not exactly sure which steps I took to do so, I have tried a lot of things yesterday before I got everything working again.
After this my phone could boot again and I was ready to play around again. I reinstalled CyanogenMod again using an older version of ClockwordMod Recovery. I'm not sure if this is related in any way, but my phone works smooth again..
Once again; I'm really not on expert on how all this stuffs works, I just hope that I can help you on the way with some ideas on how to fix your device.
So probably i have the s-off and who knows what else.

I figured out wether my device was S-OFF and/or Eng S-OFF by entering "adb reboot bootloader" from cmd. At the top of the page for me it states:
ACE PVT ENG S-OFF
I believe it stated only SHIP S-OFF when I had the problems you describe.

Thanks man for quick reply!
I definitely try the downgrading solution and i remember i too did the update for clockworkmod rom manager before the flash.
I'll report back tomorrow.
Cheers!

couldn't boot up any roms earlier after upgrading clockworkmod recovery to v3... downgraded to 2.5.1.3 and worked fine

Hi Guys, I have exactly the same problem. It would be really great if you provide me the step by step process to downgrade clockworkmod recovery.
Cheers,
Pav

I'd like to say to you guys that the downgrading solution worked
Didn't have to use any programs inside phone except clocworkmod recovery which was the only thing i had running.
Thank you user jvdminne!
The downgrading solution was in official cyanogenmod guidelines as well but forgot it anyway.
------------
Pavanka!
The downgrading solution from the link is pretty step by step actually.
But anyway, with my half-broken phone the lines didnt do the trick:
Code:
adb push psneuter /data/local/tmp
adb push misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/psneuter
adb shell chmod 777 /data/local/tmp/misc_version
adb shell /data/local/tmp/psneuter
I had to copy psneuter and misc_version to /tmp folder not into /data/local/tmp.
But anyhow, i already had # root access through computer. Probably from last half flashed system.
So only thing i basically had to do was to cd in windows cmd into folder where i had psneuter and misc_version and after that:
Code:
adb push misc_version /tmp
adb shell chmod 777 /tmp/misc_version
adb shell
in the shell (adb shell):
Code:
cd /tmp
./misc_version -s 1.31.405.6
And after that follow the instructions from previous link.
To get the ADB functions working just follow the guide here or from previous link where it had adb program included, but not sure whether it was working cause i had it from Android SDK package already set.
Hope you got some sense out of it.
Cheers!

Hey
I had similar problems to those mentioned in the beginning with the cyanogen mod...
I installed cyanogen and the it got to the screen with the blue swirlyness and then just kept restarting. I decided to restore a backup and just got stuck on the white htc screen.
I decided to follow this post and now am stuck with this...
I just tried a couple of different things to no avail...

If you had ROOT , S-OFF etc you shouldn't need to go through all this rigmarole, if you can access recovery carry out a full wipe /system /cache /dalvik-cache and reflash your chosen ROM, should be all that's required

Hey guys i have this old HTC Tattoo i would like to use for a while i need to test things on.
HTC Tattoo (Orange)
S-on
1.6.61.43 custom firmware
rooted
But i have a problem, i need to get a custom ROM on it.
so far:
1. Would not accept sim unlock code
1. Rooted it once
2. used RUU_Click_Orange_UK_1.67.61.43_release_signed_NoDriver becouse it was needed to accept the simunlock code
3. Lost root, rooted it again with Universal root becouse old method didn't work anymore.
4. Everytime i tried to open recovery menu, it shows a picture with a orange triangle and the phone next to it
5. Installed ROM manager and put Clockwork, nothing.
6. Tried to back up, install rom from ROM Manager, still nothing =(
HELP D:!
Question: How do i fix it so i don't get this trinagle thing and i can go into the recovery menu
EDIT: I forgot to add, i THINK i made the SDCard a Goldcard, but i'm not sure... how do i cheak?

still no reply? kay:

answer
1. That triangle is stock recovery which isn't useful for installing custom roms.
2. You need custom recovery.
3. You need adb.
4 You can install recovery like this one click http://forum.xda-developers.com/showthread.php?t=950759 or manualy using cmd(adb needed).
If installing manualy: You need flash_image and recovery.img .
For cmd, commands are:
adb push recovery.img /sdcard/recovery.img
adb shell
su
flash_image recovery /sdcard/recovery.img
exit
exit
Hope this was helpful for you
Sorry if you waited too much, I didn't have time to answer you.

I followed the instructions it didn't help, still same problem
no errors with the .exe, but no dice either
flashpermission denied with manual cmd
not enough memory on the device
in rom manager it says i have clockworkmod 5.0.2.0, might be the the problem that my phone is on orange or that it is S-on ? becouse i'm pretty sure it has custom recovery and it is rooted
i was able to root with this method before i used "RUU_Click_Orange_UK_1.67.61.43_release_signed_NoDriver" update
Now i am not able to use that root method, maybe it would have worked before i used it...
How do i downgrade or whatever from this RUU ?

Do you have adb drivers installed?

[How to] Restoring lost su

This is for windows but it should be adaptable to other operating systems.
Here is a quick "how to" restore your su on stock if you dont have a backup, when you have lost it for what ever reason.
To confirm you have have lost su from your system, connect your device, open up a cmd window and type or copy and paste the following one at a time:
Code:
adb shell
Code:
su
If su "#" isnt retured then do the following:
Download the LATEST OTA update zip from here-
https://ouyafw.skumler.net/
and place in your adb folder for ease of use.
Connect a wired USB keyboard to the OUYA.
Boot into recovery using -
Code:
adb reboot recovery
Upon reboot, you will likely be presented with a black screen and an Ouya icon with "!". Press the home button on your keyboard.
Using the keyboard, navigate using "up","down" and "enter" to select update from adb.
When prompted, open a cmd and enter the following-
Code:
adb sideload RC-OUYA-1.0.346-r1_ota.zip
Replace the file name above as appropriate.
Upon completion reboot system and you will have regained su.:fingers-crossed:
NOTE: When sideloading the OTA firmware the build dates are compared to one another. If you try to sideload an older version you will receive a fail. Use the same build version or above.
F.A.Q.
Q. I recieve an error stating device not found in recovery.
A. You need to install the drivers for the recovery as you did for adb.
Q. I receive an error due to build.prop
A. When sideloading the OTA firmware the build dates are compared to one another. If you try to sideload an older version you will receive a fail. Use the same build version or above.
This is tried and tested on my device.
Thanks to
@rayman for the firmware link.
Timothy Graupmann for Youtube video.

Thank you, as i have a lost su and i don't want to wait for the next OTA update i will follow this method.

Did you lose su with the ouya toolbox or via something else.

Well i think i have messed up with adb commands, after that i tried ouya toolbox with luck because the program said that my ouya should be rooted but it wasn't. I will restore lost su and then try again ouya toolbox.

Adb reboot recovery takes me to a black screen with ouya logo and " ! " under it.

Thats where you press "Home" on your attached usb wired keyboard to enter the options.

Lol i did and this would have came in handy if I found it earlier but I figured it out and install the proper su file

I can confirm these instructions work perfectly. I factory defaulted my Ouya after rooting it and lost access to su in the shell even. These steps fixed my Ouya!

[guide] root for stock lolipop roms without downgrading to kitkat

This guide worked for me. I am using v20i stock rom without any modification. I saw this on web and i want to share it. If you use this guide, it is on your own risk (such as mine)
We will have a rooted lolipop rom without downgrading to any kitkat rom. We dont need to flash bumped twrp for this.
This guide describes for windows users but same method can work with linux. Linux users know how
1- Download this file.
2- Copy zip file to your C:\ hard drive and extract there. It should be like this: C:\g3-root
3- Enter your phone's settings and activate the developer settings (with clicking build number 5-6 times)
4- Enter developer settings and activate usb debbuging
5- Enter the file g3-root and press and hold the shift button on your keyboard and right click with mouse. Select "open command window" or something like this (i am not using english windows)...
6- Connect the phone to your pc with usb cable.
7- Dont let the screen off. If your phone asks you about usb debbuging (trusting the computer), select "remember this" and click "yes"
8- now test the connection... write this into the command window
Code:
adb devices
if you can see your device's serial number, you can start now. If not, check the adb and windows drivers and try it again.
9- push the files which are needed for root with this commands
Code:
adb push g2_root.sh /data/local/tmp/
and
Code:
adb push busybox /data/local/tmp/
and
Code:
adb push UPDATE-SuperSU-v2.46.zip /data/local/tmp/
10- Now we will enter download mode of our phone. For this, discoonnect the usb cable, shut down the phone, press and hold the volume up button and connect the phone.
You will see "downloading" on your screen.
11- Now return the command window. Look your computer and verify which port of windows that the phone is connected . Mine is COM6 and i will go on with this way. You must change this with yours(COM1 COM2 COM3 COM4.... etc) . Enter this command (for COM6)
Code:
Send_Command.exe \\.\COM6
12- Next send this command:
Code:
ls
if you see the folders, everything is fine and you can continue.
13- finally we send last command and gonna be rooted
Code:
sh /data/local/tmp/g2_root.sh dummy 1 /data/local/tmp/UPDATE-SuperSU-v2.46.zip /data/local/tmp/busybox
You can see these lines if rooting is successfull
ui_print - Disabling OTA survival
ui_print - Removing old files
ui_print - Placing files
ui_print - Post-installation script
ui_print - Unmounting /system and /data
ui_print - Done !
Click to expand...
Click to collapse
if not, read and try again.
Now reboot your phone and you can see the supersu app in your application drawer
Good Luck!
I am not responsible of any damage to your phone.

Root is working but the problem is TWRP because is not working its giving error so no flashing other custom rom or mods for now.

Yes root is working fine. I didnt tried twrp or cwm. With this guide, you can use stock odexed and unmodified lolipop rom.

Root plus Custom Recovery, or Root Only?
Hi,
This is interesting and looks a lot easier than the guide I just put up over the weekend: http://forum.xda-developers.com/lg-g3/general/guide-update-to-lollipop-root-bumpd-twrp-t3048845.
But I wanted to confirm first, this is purely for rooting only, correct? In other words, if I follow only the steps in this guide I will have root...but I will not be able to install a custom recovery (like TWRP) (same as this thread: http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772)?
EDIT: nevermind, one user of the other thread confirmed my question already: http://forum.xda-developers.com/showpost.php?p=59325441&postcount=55. So indeed, this method is for root only, because this method starts with a fully-flashed Lollipop firmware (inclusive of Lollipop version boot stack - aboot.img, sbl1.img, rpm.img, tz.img, etc.).

This is a way for rooting from lollipop, and access to fastboot too.
For custom recovery, it needd bump ! , and bump works only with KK bootloader. So for having a custom recovery, we need to downgrade BL first, and inject Bumped recovery + bumped kernel after.
And if we downgrade BL, maybe we need downgrade complete bootstack too (sbl,rpm,tz,dbi,laf) ?

Just to make sure, this works for v20i only or does it work for, say, my v20h too?

Yup yup, I got it. Thanks. Just wanted to confirm.
Yes, I'm aware also of fastboot ability. Basically, dd if=/dev/zero means "writing zeroes" to whatever partition (in the case of the guide, it's the "laf" partition where "Download Mode" is stored). So, zeroing out the "laf" partition will make the device fall back to standard fastboot - except for the Verizon variant. I think you can do that regardless if you are in Kitkat or Lollipop, since the process is mere deletion of a partition's contents to "force" the device to fall back to fastboot.
Yes, you need to downgrade the entire boot stack. Basically, all partitions will need to stay at "Kitkat" version, and then manually flash ONLY system.img, boot.img, and modem.img (just like the one in my guide). And then, "bump" the boot.img so that you can install a custom recovery. I wrote that in my how-to guide as well.
In my case, I feel uncomfortable not having a custom recovery. I tinker around with my device a lot and have "bricked" it a lot of times but was saved because I have a backup via custom recovery.
I would suggest making it clear that this is for root only (meaning, does not include custom recovery). Very important, because I have seen threads from other users where they got bricked and can no longer restore at all - too bad because they did not have a custom recovery backup.

Yes, however that is a repackaged firmware (extract everything, root it, and then "bump" the necessary components, and then put it back together as a single flashable zip). That is why it will have root plus "bump" (bump'd boot.img and recovery.img a.k.a. custom recovery). Therefore, those who will download it will no longer have to root it manually. This guide (and mine) are different from repackaged firmwares, in the sense that we are not "pre-rooting" (or "pre-bumping") the firmware. We are rooting (or "bumping") the firmware after installation.

Yes, it seems it's a little different than @autoprime and you propose and i was asking myself if these three partitions were realy needed in this case (flashable zip from kdz exracted) or not.
I should prefer to let them in the bootstack version but maybe i'm xrong.

Ah, sorry I misunderstood what you were saying.
I do not know what rpm.img and tz.zip are for. I did read somewhere in XDA that tz.img is for the "radio" (or transmitter?). But I would suggest to keep those files (tz.img, rpm.img, aboot.img, sbl1.img) at "Kitkat version" because there will be a signature mismatch resulting to "certificate verify" or "security error" - if people want to have a custom recovery.
If people will NOT install a custom recovery (they just want root) then they can use this guide. The device will boot fine without the error messages, since recovery.img is Lollipop non-"bump'd" version (so the signatures match).

It should be possible to make a script that flash kk bootstack, bumped recovery and bumped kernel in a one click process, for a LP rooted.

Yes, that's another way of approaching it. Or maybe create a flashable zip from it. But we will still need to instruct users to extract their Kitkat Image files (I don't think all Image partitions are the same for all variants), that's why I find the manual method (like @autoprime) to be a good approach because I personally find it to be more "universal".
One example: the D858HK does not have cust.img.
So for us to create an all-in-one script, zip, or approach, it would be difficult because of the many variants of the LG G3. Maybe if there were not that many variants, I'm sure skilled people like you can have a universal and convenient solution. For now, I still think that manual flashing is more universal.

So that explains why even if the Lollipop versions are included/flashed, they won't cause an issue of signature mismatch. The Image file that causes a signature mismatch when you flash a "bump'd" file is aboot.img (the Android Bootloader). Which explains also in my experiment (prior to discovering it all and creating a thread) why I was initially able to "fix" my issue, following @autoprime's tutorial, when I flashed aboot.img - however, in exchange I lost "bump" status.
So basically, people will need to flash their Kitkat version of aboot.img and "bump" will still work (and will have custom recovery). That is our hypothesis at this point.
This reminds me: in my how-to guide, there was a user complaining about fast battery drain. Maybe if I advise him to flash the Lollipop version of rpm.img, that would help alleviate the issue. I will do an experiment and if this will succeed, I will update my how-to guide. In your case, for this thread's purpose, you may also do an experiment and create scripts.
Nice teamwork.
I don't know what "trustzone" is though. Will it affect signature mismatches? sbl1.img and rpm.img seem to be self-explanatory.
EDIT:
As mentioned previously, it is very dangerous to flash any of the restricted boot partitions such as sbl1, sbl2, sbl3, aboot or rpm. However it is safe to flash any other partition in order to install custom Linux builds and run them.

[How to] Fix 'sensors and camera not working', restore IMEI, etc. (Stock Pie)

At some moment when playing with Magisk modules, I've got Android crash, after which sensors (Accelerometer, Gravity, etc.) and Camera stopped working.
Obviously, somehow persist partition data got corrupted and must be reflashed. I believe, that flashing persist via fastboot is not supported, so I reflashed it via ADB, and got everything working.
What we'll need to flash persist partition:
1. Mi A2 with unlocked bootloader and critical partitions, on stock Pie 10.0.2.0 to 10.0.7.0, connected to an USB 2.0 port in PC MB; USB debugging and MTP file transfer enabled;
2. Working copy of ADB / Fastboot installation
3. image of persist partition, can be found in each stock fastboot image
https://forum.xda-developers.com/mi-a2/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824849
as "jasmine_global_images_V10.0.2.0.PDIMIFJ_9.0\images\persist.img"; must be copied to ADB / Fastboot installation directory.
4. twrp-3.3.1-5-jasmine_sprout-unofficial.img, copied to ADB / Fastboot installation directory
https://forum.xda-developers.com/mi-a2/development/recovery-mi-a2-jasminesprout-t3941096
Note: even if TWRP boots with black screen, this method should work as we'll not control process on Mi A2, instead we'll use ADB commandsthis TWRP is reported to work with all variants of MiA2 screen panels.
5. Attached command file "flash_persist.cmd", unZIPped to ADB / Fastboot installation directory.
Instruction:
Run "flash_persist.cmd" from CMD shell or Explorer (probably admin rights needed?).
Command file execution will be paused several times, waiting for ADB and fastboot commands execution.
Please read CMD window output, check that phone is being switched to needed mode and/or ADB/Fastboot commands succeed.
In case something goes wrong, press Ctrl^C and terminate batch job.
After 1st reboot from TWRP, reboot once more by standard means.
Update:
- attached f"lash_persist_V2.zip" using "twrp-3.3.1-5-jasmine_sprout-unofficial"

my mi a2 is in ARB4, I can only use MIUI, could you tell me how do I get the persist file, could also explain where TWRP comes in since the command is made by ADB?

I don't understand either why is twrp involved. I'm at stock 10.0.12 ROM, with unlocked bootloader and usb depuration turned on. Should I get the persist.img from the Fastboot image of 10.0.12? I only see the link to an unofficial one which I don't know in which way is different to the official one...

ADB.exe is sending requests to phone. Usual ROM cannot evaluate these requests, while TWRP is specially developed to perform actions specified by ADB requests.

Thanks for the reply. Now what I'm not sure is if flashing persist.img will delete my original IMEI and Bluetooth and WiFi Mac address. I don't want to lose them.

This happens to me, camera and sensors are not working. the solution for this is to flash persist.img from original and official rom. you can get that on miui official website. there you can get the persist.img and flash it on TWRP in Mi6X version not the jasmin_sprout. I have try and tested and sensors and camera on my Mi A2 is working now. Blaming myself by deleting the persist! and persist_back up at the twrp. Not to worry by lost imei and etc. mine is all working fine.

how can i do this on android 10? I say that because twrp is not available for android 10. I have problem with frond camera. it return at secondary back camera. please help me

Read OP carefully and try to Google about ADB, TWRP, etc. to understand the process. Why should we do your homework instead of you?
In brief, again and again:
1. TWRP is needed to be booted into phone, as it is the only valid means to perform ADB requests from PC.
2. TWRP has no options to reflash /persist partition from its UI
3. /persist partition image is flashed into phone from PC using ADB commands, so:
3.1. PC is to be prepared (drivers installed, latest platform-tools with ADB unpacked and tested to work, persist.img unpacked and copied into platform-tools directory)
3.2. phone is to be prepared (successfully connected via USB and then booted into TWRP with command from "flash_persist.cmd").
4. "flash_persist.cmd" is just Windows::CMD command file, helping to make ADB / fastboot / ADB requests from PC to phone/TWRP in correct order, and with intermediate checks of successful connection / mode switching: rebooting into bootloader (ADB command), booting into TWRP (fastboot command), and then reflashing /persist (ADB command)
You can read it, e.g. in Notepad, and try to understand what it should make, Googling for Windows::CMD commands and ADB commands descriptions.

Then read everything I wrote and understand what you are going to do.
Again: read text in "flash_persist.cmd" and make sure you understand each line in it.
At this I stop helping you, I'm to make my work, I'm really busy.

i've done it but my front camera still not working. when return it returned at secondary. :crying:
Then i disassembly my phone and disconnect my camera. I open my phone again and did the same thing. Finally i reconnect the camera and it works!! Thanks fo all Aerobatic

Would this work on a V11.0.6.0.QDIMIXM?
Also, where can I find the persist files for it?

Yes, it should, if this is really /persist corruption issue, and not HW problem. Diagnostics can be made running tests in engineering mode or with 3rd-party apps like AIDA64: if most or at least several sensors are misbehaving or disfunctional, this is the direct prompt to reflash /persist.
As for your question, It is always recommended to read the OP:

Latest variant of persist.img for A10 can be found in unofficial repack of 11.0.8.0 OTA, link was published in https://forum.xda-developers.com/showpost.php?p=82370929&postcount=42.
Funny fact, but someone wrote in these forums that he solved his problem with corrupted /persist (being on Pie?) using image from the 1st official fastboot image for Oreo (V9.6.9.0.ODIMIFE, link in the thread pointed to in OP and above.)

Will it work with WIfi problems in MIUI for Mi A2
I'm using Custom Rom named as Derpfest and i had also flashed MIUI 11 but my wifi doesn't works in MIUI while it works perfectly for Derpfest.

steps please?
