I was following a guide to downgrade my phone to Nougat/Marshmallow and I flashed hosd from a decrypted ruu zip and my phone does nothing but sit in a boot loop. I can't get into download mode with Power + VolDown keys it gives me the black HTC screen and goes back to looping the white HTC screen. fastboot and adb don't work because nothing is booted on the phone. Anyone know what I can do to fix this? I was running Bad Boyz Oreo ROM on Sprint and I wiped it to downgrade so phone won't boot up at all.

Update: I was able to decrypt the Oreo ruu and flash hosd from bootloader and the download mode fixed.

Tried to return to stock.. bricked HELPPP

So I was tryna dabble in returning to stock and doing some stuff so pure fusion os works on my phone. Imei,home button fix stuff like that. And I ended up bricking my phone. Everything was fine up until I flashed a hosd img for I believe it was the version I was trying to downgrade to. I can't enter download mode or recovery mode and ruu will not work. My previous firmware was the latest EU OREO. I just want to be able to enter download mode to flash twrp or somehow find a way to get back into using my phone. Otherwise, Imma be begging htc :)

So new here. I was away didn't have my phone since December I get back last week and my phone is garbage. It takes close to 12 hours to fully charge and when off the charger and not in use the battery drains about 5% per 5 minutes. It completely shuts down at between 65-75% and will bootloop until I plug it in at which point it begins at 1%. I got the 10 the first week it was released so definitely out of warranty. Will any amount of *****ing to htc or Verizon customer service get me a fix.

Hey. I get the feeling this is the wrong place to post this and I'm really sorry if it is! Happy to move it elsewhere but have no idea what I'm doing here lol.

I screwed my HTC 10 up by trying to upgrade to Oreo with Leedroid. the rom wouldn't boot. so I tried to go back (not realizing you couldn't) which obviously didn't work. anyway I ended up on PureFusion 8.0 and have lost cellular connection. (sim isn't recognized atall)

I've Google this soooo much and I can see that others have experienced the same thing but nothing I have tried can fix it. I can't run a RUU because the RUU installer just says it can't detect my phone. (tried different USB ports and reinstalling drivers etc but makes no difference - my laptop is super ancient so that's probably why)

I don't really understand what's stopping the sim card from working. I've spent about a month on and off messing around trying to sort it out and it's starting to get to me now that I'm wasting money on my contact and my phone is not usable.

I've got to the point where I'm accepting I'm probably going to have to take it somewhere to be fixed but I don't have much money and don't want to be ripped off (because I don't really know what the problem is and they might use that to their advantage lol)

can someone just advise me what I should do - if I should go to a phone shop what should I say, what kind of prices would seem acceptable? or is there a fix I can do at home? I don't care if everything is wiped off etc.

Not sure what info you need to help me but I'm S-On.. bootloader unlocked.. network is EE.

I'll be really grateful for any help if any of you can find the time to advise me!

Thanks so much.

Kellie. :)

Did you upgrade your firmware to Oreo before you flashed the Oreo version of Leedroid?

Also, what is your current firmware version (next to "OS" in download mode) If know that, I can point you to the proper RUU files that you will need
[HTC 10 Questions & Answers] kdeacs:
Hi, thanks for replying!

No, I didn't. I've always just flashed any rom and it's worked so I didn't even know I had to do that.

Next to OS in download mode it says :

2.41.401.41

but when I run an RUU it says my phone isn't detected anyway and I can't get further than that.

is an RUU definitely what I need?

Thanks :) X

As stated by Leedroid : "For the best experience, please make sure you have the latest HTC 10 OREO firmware installed prior to installing this ROM

Oreo firmware is required

Once you upgrade to Oreo there is no going back!

The current ROM base is 3.16.401.2"

Hey again! I finally managed to flash oreo firmware. the command prompt said it was successful but the phone didnt reboot (or do anything.)

so i had to force it to reboot but then it showed up my old boot animation still , and wouldnt get any further than that.

Hello,

After recieving my phone back from repair (went s-on before returning to repair) I allready messed it up..

Unlocked the bootloader because Sunshine could not make a temp root.

Flashed twrp and installed leedroid R149, tried to s-off now with magisk, did that before, but it failed.

tried to relock the bootloader, (fastboot oem Lock) and now my phone reboots as soom as it is powered.

can boot to bootloader, and download mode, but not recovery mode.

Tried to unlock Again, but it is blocked, get this error.. And can´t boot and set the OEM_unlock.

(bootloader) [KillSwitch] : /dev/block/bootdevice/by-name/frp

(bootloader) [KillSwitch] Last Byte is 0X00, disable unlock

(bootloader) [KillSwitch] oem unlock Turn Off!

Tried to flash recovery, but offcouse not posible due to relocked / s-on

Tried to place nougat ruu 2PS6IMG.zip on sd, but it gives error, I guess itøs because it's a lower version and the facts that I am s-on.

Please, any suggestions?

Do I have a brick with a completely new battery and LCD?

EDIT: Found the right RUU

[HTC 10 Questions & Answers] Daniel Z.23:
S-off with magisk ?? Maybe thats your problem. Best way to s-off is sunshine. You shouldn't lock bootloader when you are using custom rom. Do u have WWE HTC 10 X.xx.401.x ?
[HTC 10 Questions & Answers] Imonol:
Phone is up running after wwe ruu.

Yes, phone is 401.x

I meant tried to S off using sunshine while rooted with magisk.

Problem is that Sunshine gives an error saying the device is behaving in a strange way. but will adress that with the sunshine team.

Strange as I did S-off before while on Oreo.
[HTC 10 Questions & Answers] servnotif:
Hello everyone! I kept trying different things and getting into manually deleting specific sectors of partitions as some online tutorials indicated but nothing at all helped so i had just given up, particularly after looking at the cost of this phone refurbished and the cost of the xtc clip.

Last weekend I happened to see my phone abandoned in the drawer I last left it and decided to give it another go. This time I was able to find in a Russian forum a different RUU which actually has a superior version number than every other RUU i had found before and I was incredibly happy to see my HTC BOOTING AGAIN! :laugh::good::good: It is absolutely CRITICAL to find one RUU that matches absolutely everything including OS version, which was very hard with this carrier, I hate it!

Everything seemed fine except ONE mayor detail: "No Service". So, Radio not working. I realize many went through this side effect after flashing SuperSU and every place mentions it's because the forceencrypt flag is not set so I started troubleshooting that way.

I tried reflashing the RUU several times, no success. I figured I should still try S-OFF to make things easier. I tried again the modified SuperSU(s) to get root, then I get the boot loop again until i reflash the RUU. All forceencrypt versions did this. Eventually I downloaded the latest version of the flashable SuperSU and manually wrote in the shell the command to set the forceencrypt flag then VOILA! No boot loops and I have SuperSU finally.

Naturally I downloaded Sunshine S-OFF, had a few tests done, paid the license (after all previous issues, getting S-OFF for the license amount is nothing!) and after a few restarts the phone was S-OFF. Hurray!

Phone is currently on SuperCID, I followed this guide https://xdaforums.com/htc-10/how-to/guide-how-to-drand-convert-htc-10-to-t3374593 to debrand the phone but after all flashings done correctly, it got stuck in the white HTC logo.

So, I flashed the official RUU for the North America Unlocked version from the HTC website as it matches my MID and it booted successfully, however, still no radio :(

I tried flashing several radios, done the "fastboot erase modemst1" and modemst2, right now i just finished flashing one of the older RUUs from my carrier, nothing, radio does not come back.

It indicates "No Service" and when I get to the menu to "Search for Networks" all that section is grayed out.

Once again I ran out of ideas to get the radio back working, any suggestions are very welcome and I highly appreciate it! :)
[HTC 10 Questions & Answers] SecurityCze:
servnotif's little problem :)

Hello,

have you tried restoring that backup you made with TWRP? You tried RUU for your carrier and unlocked NA? None of them worked right? Have you tried custom ROM?

Also you can also try going into diagnostic (*#*#4636#*#*), I think there was something regarding network reset (if I'm not mistaken)? ¨

Do you have IMEI (*#06#)?

Wish you luck :good:
[HTC 10 Questions & Answers] servnotif:
Hi there! Yep tried all that, IMEI didnt show on the OS but it did show on Download Mode.

Now I'm back with even better news! I realized in an attempt to debrick it months ago, I might have flashed an Oreo ROM.

So i did this: https://xdaforums.com/htc-10/how-to/solution-imei-signal-downgrade-oreo-8-0-t3748999 (fastboot erase persist) then reflashed and signal is BACK!!! Phone is 100% resurrected and S-off now, ahh feels sooo good :D

Hi guys, my htc 10 just freeze in a black screen after the green htc logo. I turned it off because it had 1% battery, after that the phone did not pass that black screen. So i had to do a factory reset for use the phone Im in android 8, bootloader unlocked and rooted.

I had the same problem trying to install the viper rom and leedroid rom. Any idea of what is happening?
[HTC 10 Questions & Answers] Mr Hofs:
Do a factory reset, and there is no such thing as a battery repair app. Google for battery recalibration and follow the procedures.

This is the third thread, please stay in 1 for a while as i see it as spamming the forum. I see 3 notifications and all 3 are the same. Not needed at all.

Cheers.
[HTC 10 Questions & Answers] onewhackmac:
Hmmm I have calibrated it several times as well as some tricky asian techniques to reset the battery but it doesn't do anything.

Factory reset seems to have made it worse, its draining as fast in ULTRA saver mode now.

M8 it's my first post so ease off, ok. If anything delete thread duplicates or I'm going to think there are mod heirarchies.

Is it normal for an 8 minute youtube video to burn 20% battery?

Has anyone UNDERclocked this beast of a processor as that might be the trick..

[HTC 10 Questions & Answers] onewhackmac:
Reporting back on the posts once more for consistency -- unrooted stock update to Oreo has fixed all bootloops, battery dropouts and drain issues, 5% total drop in efficiency

huge disrespect to HTC but maybe their catalogue has a 6.0/7.0 fix. Seems to still have problems with background use of things, for example I found that my contacts list was the

main offender this time @ 5% use, weird af.. Gonna root this asap, then start working on the clock speeds to get some V drop gains, definitely some territory there while not

beasting Hearthstone or oldschool nintendo : - )

See above, might be your ticket as well!

Personally I've never had any luck windows to droid, use a linux cd and sudo equivalent to drop code to a bugging flashboot, if you're fast it should get through gl
[HTC 10 Questions & Answers] EdHaku:
Unfortunately, no. I can get it to turn on, but it'll bootloop after just a few seconds using it. I'm too scared to risk returning to stock/updating it with a RUU in this state. What if it bootloops during the installation? I might really have a hard brick if that happens.

Reboot loop

Hi,

I am putting my primary phone in for a warranty claim and had to dig up the old HTC 10 to use as a backup. It was fine until it prompted me to update to Oreo which I did causing it to be stuck in a boot loop. I am willing to flash it to the previous firmware but I am struggling to figure out how to do it. I have some screenshots of the bootloader and did try following these steps on

I also have no idea of the CID so do not know which FW to flash with! :(!

I have screenshots I can send of the boootloader if anybody has any idea.

Any assistance that can be provided to downgrade it to Nouget or make it successfullky boot into Oreao would be grreatly appreciated.

So far so good. These are the steps i did and this is what happened:

-Unlocked my phone

-installed TWRP 3.2.2.1

-deleted all the files on my phone

-flashed lineage-14.1-20180721-nightly-pme-signed

-tried to flash open_gapps-x86-8.0-micro-20180725 -> error 64

-installed TWRP 3.0.2.0 (to solve the error 64)

-not able to start TWRP

-Lineage is booting, but it will end up in the password error: default_password / my pin is not working

-Download mode not possible, since my phone is empty

-adb in command won't find my phone, my pc is not accepting it either (driver issue since i can't enable usb debugging)

Shall i get an micro sd card for any possible flash case, or is there a way to get TWRP to run?
[HTC 10 Questions & Answers] Mr Hofs:
Hold volume up and down + power, and you can access download mode. Just because the phone is empty it doesn't mean you can't access it, you can't delete download mode as its not a part of the rom.

And don't flash lineage 14 as its NOUGAT, you can't run nougat roms on OREO firmware as you say you are one Android 8.0. Flash 15 instead, that is based on Oreo firmware. It is written in the rom thread.

If my phone dies while flashing a RUU, does that risk bricking it beyond repair?

And on that same note, I'll ask again. Does any HTC 10 battery work for any HTC 10 device? I have a 2PS6200, and fear that maybe the B2PS6100 will not work.
[HTC 10 Questions & Answers] Mr Hofs:
1 : yes, thats why you must start with a battery that's charged to 100%. Why take the risk and start doing these kind of things with a battery that's half empty or even more.

2 : why not just go with the original just to save yourself from the risk.

Better be safe than sorry......
[HTC 10 Questions & Answers] EdHaku:
I can't charge it to 100% because the battery is dead.

I can't go with the original because I can't find it.
[HTC 10 Questions & Answers] Mr Hofs:
Flashing a ruu needs at least 30% but that's no guarantee.

So it is like this :

1: replace the battery

2: use the phone (custom rom or stock, that should not matter)

3: why can't you find it ? which one do you need. If you gave this info with your original post we could already have had a look if we could track it down

I was referring to the RUU, not the battery. Batteries i don't know, why not ask it in a nearby phone repair shop ?

They don't work with newer HTC devices around where I live. I'll do it myself in hope to fix the bootloop.

Clearing cache in recovery mode only forces device into another bootloop, wherein the battery has drained again --

bootloops are not as aggressive as in Nougat.

had an issue connecting to PC so installed drivers and even HTC Sync Maneger, yet the phone wasn't recognized.

opened the recovery mode and basically wipped everything including sys. "1st mistake."

no backup nothing and there was no SD at that point.

now that I've got an SD Card tried installing https://androidfilehost.com/?fid=673956719939813763

that with S-on so it actually removes twrp and get back to stock recovery which actually doesn't open.

so downloaded: https://xdaforums.com/showpost.php?p=75309361&postcount=2573

the file up there.

thing is phone doesn't read the file,

tried two different other ROMS and it says terrible mishape or CID failed.
