Downgrade Verizon HTC 10 from 8.0 to 7.0 - HTC 10 Questions & Answers

Is it possible to downgrade HTC 10 (Verizon) from 8.0 to 7.0 with S-on? The GPS stops working after I updated from 7.0 to 8.0. So, I want to learn how to roll back to 7.0. Thanks in advance.

I think you need an unlocked bootloader/twrp to perform that procedure, no? And his Verizon variant can't have its bootloader unlocked, only s-off.
OP, why don't you try running the Oreo ruu for Verizon? I don't think a broken GPS is a known issue for the Verizon variant of Oreo, so a fresh ruu might help you troubleshoot the issue. You can find it on the Verizon 10 forum on xda.

Tamira, does "running Oreo ruu for Verizon" means flash it with the ruu stock oreo of Verizon found in this thread https://forum.xda-developers.com/verizon-htc-10/how-to/verizon-official-ruu-1-19-605-9-t3377586?

That's correct, sir.
Obviously it'll wipe your phone completely, so back up what you need first.

Is the phone needs to be rooted while s-on with bootloader locked?
Which RUU should I choose among those listed below?

None of the above as they are firmwares, you need the ruu.

Thanks, Mr. Hofs. I was able to flash the RUU you recommended without any problem with unrooted, S-on and locked bootloader. The process is exactly as Tamira instructed:
Download the zip
Rename to 2PS6IMG.ZIP
Copy it to the root of your SD card
Boot to download mode (hold down and power upon boot)
Follow on screen prompt
However, the GPS problem is still there. From the threads I read, I can't do the same for the older RUU to go back down to Nougat unless I root the phone and have bootloader unlocked? Will I brick the phone if I attempt the flash the RUU for Nougat?

Nougat isn't going to change anything for you.
If GPS isn't working after flashing the Oreo RUU and making sure that all location settings are on, then you have a hardware issue.
Changing software to an older version, won't fix hardware.

No worries, but if you insist to downgrade you need to send your phone to the sunshine team to make it s-off.

Going back to Nougat seems to be unnecessary at this point. Thanks to all again. I at least finally was able to flash the phone although there are many things to learn such as rooting, unlocking boodloader, s-off

That's nice, but you need to be S-Off to do certain things, like manually flashing firmware without reverting to stock, or using firmware meant for carriers other than yours when they update before your carrier.
There are other advantages as well, but these are the ones that S-Off is most used for.

"WTF what are you doing" indeed. Rumrunner never worked for this phone. It was for the M7. Firewater (related, but different from rumrunner) was for earlier M8 versions. It was an online service, and will no longer work now that the dev has stopped supporting it (so don't even bother asking).
For many variants, s-off is not needed to update firmware (as long as Lollipop has been released for your variant). You can just return to stock ROM and stock recovery, and OTA to Lollipop in order to update your firmware.

There are different stock ROMs for different CIDs. Plus, if you have no WiFi, and extreme long boot times, its due to your firmware not being supported by the ROM. You need to find the stock ROM for your current firmware and CID. Then you also need to flash the corresponding stock recovery. After that, you can OTA to the latest firmware.
What is your CID, hboot number, and radio number?

Not only is that make a difference, it makes it easy to update your firmware. Just relock the bootloader and run the new Lollipop RUU: http://dl3.htc.com/application/RUU_M8[email protected]50319A_40.45.C33065.00_F_release_426617_signed_2.exe
Backup any important personal data before RUU, as RUU will wipe the phone.

1) To lock bootloader: Connect phone to PC (PC required for RUU). Boot phone into bootloader-fastboot mode. Open command prompt on computer, and type command: fastboot oem lock
2) Download RUU onto PC. With phone connected, run the RUU exectuble program on the PC and follow the instructions given.
3) Done, drink beer
A little more detail is given here under "Manual system update instructions": http://www.htc.com/us/support/htc-one-m8-att/news/
But seriously, the RUU is a self-explanatory program. It will tell you to confirm a couple dialogue boxes. But aside from that, the program will install a completely clean factory Lollipop software image.
Option Step) Unlock the bootloader again via HTCDev.com, then flash TWRP if you want to root or flash a custom ROM.

You can try it. It certainly doesn't hurts, as it only takes a single fastboot command, and would be faster than going through the whole HTCDev.com process (although that really doesn't take that much time, either).
I know using the same token has worked on past HTC devices. But I haven't seen much (if any) success on the M8. Most (or all?) folks have had to get a new token in order to unlock.
tugratolunay said:

Yes, whatever AT&T apps are present on the stock Lollipop AT&T image will be on your phone. Simply root and delete/freeze, or install a custom ROM to be rid of the AT&T bloat.
tugratolunay said:

You mean the removable SD? It should be safe. But you can always take it out before RUU to be sure it doesn't get touched by RUU.
Any other data on the phone (including the "virtual SD" AKA internal storage) should be backed up, if you want to keep it. Internal storage "might" be okay, but I'd back up anything you want to keep, just in case.

Usually booted into OS works. But some folks have had to put the phone in fastboot mode.

Yes, that is normal. Its expected that RUU will be run once you relock, so it makes the phone this way.

After installing this RUU I will have original At&t rom and unroot, relocked bootloader phone. and it will be 5.0.1 lollipop. Am I right? and so firmware will be upgraded tho? That means I can Unlock it, root it and install that android revolution HD rom without having problems.

Yes, yes, and yes.
The only thing above that isn't completely correct, if that after you unlock the bootloader again, just install custom recovery and flash ARHD. No need to root before flashing a custom ROM. Installing a ROM wipes whatever you did with root anyway, and custom ROMs are always pre-rooted. So rooting manually is an unnecessary step. You only need to root "manually" if you are keeping the stock ROM.

Returning to stock issues.

I'm currently running Android Revolution HD on my new M9, unlocked, s-off also.
Found out that I have the battery is faulty, so I need to return it to stock, and get it back the shop for a replacement.
However, I stupidly didn't make a back up of my stock rom.
The CID of my phone is O2___01
I've downloaded the stock rom from this site, and flashed it using the RUU command. However when it flashes, then tells me to reboot, it still has Android Revolution HD on it.
I've spent a few hours browsing the forum, and still I've come to no avail.
Any help would be well appreciated!

You don't provide much information so it's hard to help. So let's start at the bginning: What firmare version are you using? (It's stated in Download Mode in the line with "OS" at the beginning.)
You tried to flash a RUU? Which one? Have there been any error outputs? If yes, which ones? Since you're S-OFF flashing a RUU should not be a problem at all so these outputs are very important if you want any help.
I tried to flash 1.40.206.8 -> 2.10.206.2 from this page

As far as I know Sneakyghost doesn't provide any RUUs. Those are only firmware packages that do not contain a rom. So it's no miracle that you're still booting ARHD.
You can download O2 RUUs from here, here or here. Any of the X.XX.206.X files will work since you are S-OFF. Do you have a SD card that is not bigger than 32gb? If yes, format it to fat32, copy one O2 RUU to its root directory and rename that file to "0PJAIMG.zip". If you then boot to Download Mode you will be asked to push the Volume Up button and the RUU will start flashing. If it reboots to system instead of rebooting to Download Mode you will have to power off your phone and boot to Download Mode manually. The RUU will continue then. At the end you will be asked to push the power button so that your phone gets shut down. If you now start your phone you will be back on a stock system.
Be aware that there is no RUU for your current firmware. Since you're S-OFF that doesn't matter but your phone will be downgraded at the end.
Ahh no wonder! haha
Going to try this shortly, so will let you know how I get on!
After its flashed, I'll be good to lock again and go s-on? Then return to the shop?

Relock only after you successfully tested that your device is booting normaly. After that you theoretically could re-S-ON. (But I would never do that because there is always a risk of hardbricking your phone if you re-S-ON and there is anything still modified that you didn't notice. For safety reasons S-OFF should always be considered as a oneway.)
Edit: I'm not completely sure but I actually doubt that they will check whether your phone was S-OFFed or not. If I think about the people who are working at the O2 or vodafone shops in my city I would say they do not even know what a bootloader is...
Agreed, use the s-off command to change back to "LOCKED" and leave it s-off. Too much of a risk otherwise.
If in the unlikely event they see it, you can play dumb, because a few rare people have gotten s-off phones from the factory and it doesn't prove you did anything.

Help with installing AT&T Ruu

I'm a very new android user, so please forgive my ignorance.
I'm using a sim unlocked AT&T M8 outside USA with a different carrier. Right now, the bootloader is Locked, CID is 11111111 and S-OFF. I've downloaded the official marshmallow AT&T RUU for m8 from htc website.
I follow the install instructions until the update actually starts. Then it stops after about 10-20 seconds and shows Error 155: unknown error and enters into the recovery steps (in the RUU). My current software number is 4.28.502.2 and im trying to update to RUU_M8_UL_M60_SENSE70_ATT_MR_Cingular_US_6.20.502.5
Can someone please help me out with this? I've been trying for over a week now. I will never receive the OTA's since I'm not using an AT&T sim. So RUU is the only other option left. Thanks a lot in advance.

Thanks for your reply man, but im extremely lost here. Could you please guide me step by step? I've downloaded the firmware. Where do I put it? I've tried the adb folder. But it show error: can not locate firmware.zip.
Edit: Another question. Is that firmware applicable for my device?
The firmware is applicable BUT since you're using your device outside USA and not on AT&T carrier, S-Off .. the best thing for you to do is fully convert your device to other region, maybe a EU region or Dev Edition .. more suitable for you.
I read somewhere, with the latest firmware you may have calls problem due to Voice HD implemented by AT&T
If you're interested in converting, I will guide you (when I am available)

That would be very kind of you, thanks. Though, i think I've already messed up my phone. I finally got to update with the firmware in the link. The RUU was going on smoothly as well, until it reached 38% when Error 155 showed up again. The phone then went on to the bootloader screen with no options for fastboot, restore or such. I restarted it and entered the bootloader. My firmware is being shown as 6.20.502.5 but when rebooting the phone it won't go past the screen with the HTC logo. I'd be extremely grateful if you could help me out of this mess.
Also, when i open htc sync man, OS number and HTC Sense number shows up as blank, while the firmware number is shown as 6.20.502.5

Aren't you supposed to uninstall Htc Sync Manager before you run the RUU ?
That was clearly stated in link that I gave you earlier, and you also need PC with USB 2.0
Uninstall HTC Sync Manager but leave HTC USB drivers then try again to run RUU after you put the device on bootloader/fastboot mode.

Yeah I did. I re-installed it later to see if it would show any information.
Most important is RUU must complete 100%, no error 155
I never use Htc Sync Manager, so I don't know what is shown there.

I'm using a sim unlocked AT&T M8 outside USA with a different carrier. Right now, the bootloader is Locked, CID is 11111111 and S-OFF. I've downloaded the official marshmallow AT&T RUU for m8 from htc website.
I follow the install instructions until the update actually starts. Then it stops after about 10-20 seconds and shows Error 155: unknown error and enters into the recovery steps (in the RUU). My current software number is 4.28.502.2 and im trying to update to RUU_M8_UL_M60_SENSE70_ATT_MR_Cingular_US_6.20.502.5
Can someone please help me out with this? I've been trying for over a week now. I will never receive the OTA's since I'm not using an AT&T sim. So RUU is the only other option left. Thanks a lot in advance.

I don't know if it's the problem,but did you try the RUU after unlocking your bootloader as you are S-OFF?
I think it's supposed to be unlocked if you have S-OFF.
Edit:Just got to know that S-OFF devices have nothing to do with unlocked or locked bootloader.
Why don't you try a EU RUU?Mine was also a AT&T device,but I converted it.

Hello there. I kind of made it work. What I did was take the rom.zip from the ruu file and flash it via htc fastboot special. And it worked well. The only problem I'm facing now is that the boot animations are EXTREMELY slow. But once it's past that, everything seems pretty normal. I wiped the cache from recovery but that didn't help. Do you have any suggestions for me?

Meaning the boot animations are slow every time you boot, or just the first time (its unclear from what you've posted)? First time booting after RUU will be slow, due to cache being setup, etc. And clearing cache will cause that process to repeat when you start up again.

Neither of those statements is entirely correct.
With s-off, you can run an RUU with bootloader locked or relocked. Essentially, the check for the bootloader unlocked condition is bypassed with s-off.
But having the bootloader locked still means its locked (even with s-off). Meaning you can't do things like flash custom recovery with bootloader locked (even with s-off).

Hello there. Thanks for the reply. What I meant was, the boot animations are slow every time I reboot the device.
Things I have already done:
1. Flashed the rom.zip again.
2. Factory reset.
3. Wiped the cache from recovery multiple times.
4. Restarted in all possible ways. Normal restart. Power off, wait 10 minutes and power on again. Pressed the power and volume up button for restarting. Reboot via fastboot.
I'd really appreciate if you could help me out.

Since you've already flashed the RUU again, I don't think there is much else you can do. Maybe its a common issue with the new build?

Man I searched EVERYWHERE. People dont seem to have any problems like this. What I did find out was that this might happen if the firmware or kernel numbers dont match (or something?). Can you tell me if I did anything wrong?

That only applies to flashing ROMs in custom recovery. WHich is completely different from RUU. RUU re-writes all partitions, including firmware, kernel, ROM, and a bunch of others. So there isn't a possibility of a mismatch; as long as the RUU ran properly. And since you ran the RUU twice, you pretty much eliminated the possibility it didn't install completely.
Some other options you may consider:
1) Unlock the bootloader, flash TWRP custom recovery, flash a different ROM and see if the slow boot issue persists.
2) Change CID and/or MID (which you are free to do since you are s-off) and try another RUU; such as Developer's Edition or Euro.

Which version do you want to "convert" to?
Dev Ed is easy, it shares the same model ID (MID) as AT&T, and you already have SuperCID. So all you would need to do is run the MM Dev Ed RUU: http://dl3.htc.com/application/RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4.exe
Euro is a bit more steps, you would need to change to the Euro MID: http://forum.xda-developers.com/showthread.php?t=2708581
Then run Euro MM RUU, noting that relocking bootloader is not needed for you (since you have s-off): http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6

M9 Stuck in a permanent boot loop even after hard reset :(

Hi everyone,
It would appear that my phone is stuck in a permanent boot loop. I'm still on the latest official rom from my carrier, it's not rooted nor have I made any changes to the bootloader.
The only thing that I did was restart my phone from within the OS after I couldn't launch the official SMS app (some MMS process error).
Now I'm stuck in a boot loop where the phone doesn't get past the first "HTC" logo page. I also notice that there are two thin dark horizontal lines on the top and middle of the screen that weren't there before. They look like clusters of dead pixels and are across the whole screen.
I've tried using the official bootloader to do a factory reset and wipe cache but I'm still having the same issue.
What else can I try? Is it safe for me to unlock the bootloader and try flashing a custom ROM while the phone is in this state?
I'd try to look for an RUU that matches your firmware before trying anything else.

I've tried to find it but I'm not having luck.
Since I'm S-ON I can only flash the ROM with the same firmware and I've figured that I need:
version: 3.35.166.12 for CID: VODAP120 (A1 Telekom Austria).
Now in case I can't find it, I would need to unlock the bootloader and flash a custom recovery.
However, since there is no way to go S-OFF without actually booting into the phone is there a risk of bricking the phone when trying to flash a custom ROM?

If your phone has a warranty send it back. For it to bork the way it has it was probably faulty, unless you know something we don't..
You could revive the phone but it may still have a fault.

Hi guys,
Thank you very much for the friendly help. I've found the RUU file and it revived it. Wasn't free though (ir-file.com).
When I get the time I'll re-upload it and make available in one of the RUU threads.
Anyway, the first thing I did was to unlock the bootloader, install TWRP, root and finally S-OFF. If I had TWRP to start with I could have avoided all this hassle and just restore the boot partition for example.
However it does worry me a bit that such a thing occurred out of the blue. Are there any ways of checking if there is storage corruption, bad sectors in memory ect?

Hold the power button and volume down while booting. The OS line will show you the ROM version that you have to look for when trying to find the RUU. You need to install ADB and Fastboot and run a special command to read the CID and other device data. Something like allvars, can't remember exactly, did it a year ago when I got the phone

Hi guys, I am in the exact same situation and don't seem to be able to find the appropriate RUU file for my phone. Can you please give me some indication regarding how to find it.
So far I managed to unlock the bootloader, install TWRP and attempted flashing several RUU files without any success whatsoever.
Thanks a lot in advance!
Cheers!

I have a T-mobile HTC One M9. Can I update to nougat using the unlocked RUU?

Hi, I was wondering if it is possible for me to use the stock RUU to update to nougat on my htc one m9 rather than waiting for t-mobile to release a verified rom later in the year?
Yes u can. Just make sure that u are s-off and bootloader unlocked and then flash the dev edition ruu and u will get nougat.

Not quite. To flash the developer RUU on a T-Mobile branded M9, you'll need to change your MID & CID to match the SKU of the developer edition RUU. If you don't know about these acronyms, stop what you are doing and read up. The FAQ section of the M9 readme thread, question 9, walks you through converting GSM phones (like the T-Mobile version) to the developer edition.

Not until Sprint releases the Android Nougat update.
The only update the is currently available is for the developer edition of the M9, a GSM model. Sprint is a CDMA carrier and incompatible with GSM.
Thanks for clarifying.
And you cannot flash on sprint or cdma phones. The ruu is only for gsm phones.

RUUs have the firmware along with everything else. While I'm pretty sure there's a way to flash individual components (radio, firmware, et cetera), that is beyond me. I stick to using the RUUs, and recommend them heartily. The easiest method is the SD card method - outlined in that same post. You'll end up wiping your internal phone storage (so back up what you care about), but it'll get you to the latest and greatest for the M9.

Really? I read that you couldn't use an RUU because verify key on firmware v1-3 is different from the one on v4, so you need v4 firmware to use a v4 RUU, which requires using a method. So I converted to dev/ATT/unlocked, flashed a v3 RUU I found online, and now I'm going to try to update to v4 which is apparently safer. If this fails, I'll try the RUU. After all, this is all vanilla to HTC so it should tell me if it won't work.

I'm pretty sure the issues about keys has to do with trying to downgrade. But that's above my knowledge level.
I know for sure that you can apply the Nougat RUU after the Marshmallow RUU without issue because I have done this myself.

Tried to use an RUU. Got a signature error of some sort. Can't remember the number. RN it is taking OTA updates smoothly. Now, it will either get to v4 eventually through the OTA updates, or it will cut off at the top of v3 (in which case I have done something horribly wrong). I will try to flash RUU after I get v4 through OTA, just for fun and for the sake of the community
Edit 1: v4 finally showed up through OTA. 2GB Downloading currently. Will still RUU to double check compatibility. Will post back with success or not.
Edit 2: v4 was successful, device convered to HIMAULATT. Now flashing the Dev RUU, which works. It didn't work on v3. Therefor I was correct, and RUU v3 -> v4 isn't compatible.

Going from Marshmallow to Nougat is definitely possible (I've done it myself) - I'm not sure why your phone gave you such troubles. But in any case, I'm glad your phone is fully updated! Congratulations.
