[Q] Anyone online to help me with a semi-bricked Z? - G2 and Desire Z Q&A, Help & Troubleshooting

Hello!
I have an HTC Desire Z stuck in bootloop.
It's an unrooted, S-ON version.
I have tried the PC10IMG.ZIP via SD card route to no avail - don't know if that's because I couldn't find the right RUU. It seemed to get stuck at user data deletion.
I've now downloaded ADB and fastboot and managed to get the device recognised, but I have no idea how to go on. (All very new to me!) I am also having difficulties finding the right RUU/ROM for this. I *think* I found it on htcdev.com as 2.42.405.4, although it's in a tar.gz extension that I am not sure how to extract.
Another issue is that occasionally whilst in fastboot the phone seems to time out / switch off for no particular reason. It shouldn't be a battery issue but I am letting it charge for a bit just in case.

Anyone has any idea of how to progress? Would reeeeally appreciate it!

Erratic progress from yesterday:
* Have managed to extract the folder from HTCdev, but I don't see anything I immediately recognise as a ROM and therefore I am still stuck
* Would be happy attempting some of the recovery modes, but I don't understand if they work on S-ON, and if not if there is a way to bring the phone to S-OFF via adb or fastboot. And a hand-hold on selecting a recovery would be LURVLY.
Apolz for being such a noob, but considering I didn't even know what "rooted" meant yesterday, I feel emboldened

Next, I tried this system: http://forum.xda-developers.com/showthread.php?t=1572924
I get an error "Can't open /cache/recovery/command" - this is actually an error I have been getting very often
I tried manufacturing the folder and leaving it empty but it didn't make an iota of difference.
When I run the update I get an "Invalid operation" message and then it just reboots (i.e. gets stuck on HTC logo)

any ideas where im going wrong?
You need to cd into the directory where you have your psneuter and etc files...
so cd then adb push etc?
will give it a go
thanks
woo-hoo i have temp-root, am i correct in saying i will have temp until i restart the phone - when i will have lost it?
Yes, restarting will remove a temp ROOT.
Follow this guide, from step 2. Make sure all your files are in the same place. This means when you open CMD prompt you must be in the right directory (C:\<location of files>\) when you run your ADB commands.
all seemed to be going well, got temp root, reloaded into bootloader pressed the power button, it appeared to be loading the new rom, but it didnt, im still on 1.72
cool, managed to downgrade to 1.34.405.5 just need to find the easiest way to root it is now
Use the guide i linked above, it was the easiest way for me to permanent root the phone. It uses psneuters, gfree and then root_psn. It will also give you clockworkmod 3.0.2.4
ok, i downgraded from 1.72 to 1.34, ive got perm. root and want to install a custom ROM, problem is clockwork wont backup my current (stock) ROM, it reboots and freezes at the white htc screen.
anyone shed any light on why i cant backup?

I think I BRICKED it....

So, I might have made a mistake... got my M8 today (yay) and bought it used with GPE rom on it. Well the software kept messing up and I wanted to go back to stock... well I tried fast booting and using a RUU which failed (too many links). I decided to then unplug it and found a horrible screen of htc logo and 4 exclamatory triangles. I can access bootloader by unplugging the device, but the only option is RUU. cannot seem to get anything else.
Connect the phone and post the results of fastboot getvar all and we'l take it from there. If you can also post a screenshot of the bootloader screen that will help

Bricked my HTC One M8 - No OS

Hi everyone!
OK, I'm sick as a dog, so I know I shouldn't have been doing this today, but..
I was trying to update my HTC One M8 with Cyangenmod, (cm-13.0-20160314-NIGHTLY-m8). I had been having problems with TWRP reading my SD card, so I decided to go ahead and wipe my phone and try reinstalling using fastboot. I used TWRP for the wipe, but I used the advanced option, and it seems that I wiped everything, including the OS from my phone. Now, all I get when I boot is this screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I have tried holding the power and volume down buttons but I can't get back to the recovery. Both adb and fastboot do not seem to be able to see my phone:
Does anyone have any suggestions one how I can fix this?
Thanks

Can you go to bootloader or only this screen ?

Only this screen. My phone won't even power down.
OK, I was just able to get into the bootloader and I can also get into TWRP. I have a micro USB chip that I can put into the phone. Should I copy the files onto the chip and use TWRP to flash? There is also an option for "adb sideload" in TWRP.
Whew!
OK, using sideload, I was able to flash Cyanogenmod back onto my phone!
Every thing should be fine now! (fingers crossed!)
You also can copy files with mounting from twrp.

TWRP continuously presents the same message?

Hi Everyone,
I have unlocked the boot menu on my One M9, and installed TWRP (https://dl.twrp.me/hima/twrp-3.0.0-2-hima.img.html).
However I have a sneaking suspicion that the custom recovery is not working correctly. Every time that I boot into recovery I see the same message (shown below). Every time that I see the message I tick the 'Never show this screen during boot again' checkbox, and then swipe the 'Swipe to Allow Modifications' button.
Why am I seeing this message over and over again? Furthermore what does seeing this message actually mean? As a side note I appear to be able to install ROMs (Android HD, and Venom) - log files show successful ROM installation - however I cannot boot into them, instead I simply find myself at the bootloader screen whenever I start the phone.

Any help here would be great! I am currently unable to use the phone, and would ideally like to start using a custom ROM. However if doing so is not possible it would still be good to work out what is going on before I make the move back to the stock ROM.
Kind Regards,
Davo
that is normal, if you won't use stock roms again, just select never show this during boot again and swipe to allow system modifications. then you can normally flash roms without any problem
That is exactly my point! I have already followed your suggestion over ten times...but the message keeps appearing regardless!

Fastboot Flash Failed

Device: Moto G6 Play (XT1922-2) from the UK
While using the device, it suddenly got really hot and then turned off, tried restarting it, after it cooled down a bit, but in vain.
When turned on again, the "Startup Failed" screen appears. I tried Motorola's "Rescue and Smart assistant" to solve the problem and followed the procedure. While fastboot was being flashed, it stuck on 67% and then it said "Fastboot flash failed".
Tried again, but every time there were different new messages (sometimes the device was not recognised, sometimes says "Model name missing" etc).
I then did a bit of research online and the general gist I got is to reinstall AndroidOS with Minimal ADB.
I'm just unsure which method to use as there are several methods for several versions (e.g. there are several XT****-*s). Also, I'm not sure because youtube demonstrators were using working devices and the screen of my device is very different than the others (Neither the green Android Bot nor I could use the volume up/down button to access modes)
Please excuse my lack of technical ability and I hope I could explain the whole scenario. I am also new to XDA so excuse the lack of general tradition on this site.
Now, the question I want to ask is this: If it is possible to unbrick (I'm thinking it got bricked), if so how? Also, does it matter which stock firmware is installed? (Like what's the difference between XT1922-2 and XY1922-7 for example, just curious) Also, the device doesn't power up anymore. The screens only appear when micro-USB is connected.
Any help would be very much appreciated.

Hello sir
Have been trying to use Rescue and Smart assistant" to solve the problem and followed the procedure. While fastboot was being flashed, it stuck on 67% and then it said "Fastboot flash failed".
Tried again, pls what can I do?
