N950USQS2BQL9 <--- How the firmware is displayed

N950----US----QS2-------BQL9 <--- How to read it.

Product------Market-----BootLoaderVersion-----Firmware Version

So there's a bulk answer. The bootloader can NOT be rolled back, so yes going to U2 you cant go back to U1 officially.

The updates are 99% security fixes by google, nov, dec security patches etc... some of the stuff like volte came with the latest updates.

Oh and to add to this, this Rom flash will not lock you to u2 if you are on u1. You would need to delete boot.img from the Rom and flash as the img is the u2 boot.img and doubt it will boot with a u1 bootloader.

I've had testers flash u2 software on a u1 bootloader and it boots so just saying you can flash and run a u2 rom on a u1 bootloader.

just install the *.cab

(copy to your device and run the *.cab)

or search a prog named "cab via activesync" and install *.cab´s from your desktop

Make sure that you've closed down your currently installed Comm Manager (through Task Manager) before you install.

[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] singhnx:
Through the task manager?
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Confused Stu:
Singhnx is right - you've still got it running. Bear in mind, most Task Managers will count the Comm Manager as a background process and so won't show it if it's running. You need to kill it through the Running Programs/Task Manager (depending if you're WM6 or WM6.1) option under Settings > System. Even better - carry out a soft reset and then run the cab as the first thing you do.

[One (M8) Q&A, Help & Troubleshooting] Sir Lucifer:
Dear XDA developers, professionals and programmers:

Recently I came across a good deal (HTC M8 in mint condition) and bought it. It was running Android 4.4.4 and I was happy with it till I read that it could be updated to Marshmallow. I followed a few links and after some time discovered that it was originally bought from the USA and locked to AT&T even though the installed rom was WWE. Stupidly I downloaded Marshmallow update for AT&T (RUU) from the HTC website and ran the installer. The installer completed successfully and the phone now runs Marshmallow with Sense7.

Since the rom was filled to brim with useless AT&T crap that does not work outside AT&T network I decided to switch to developer WWE rom but the RUU refused to install on the phone (I have S-Off)

After doing a bit more reading I discovered it was because my new rom has a software number 6.20.502.5 while the RUU I would like to install has a software number of 6.12.1540.4

I googled and googled and searched and searched but could not find a single tutorial to explain how I can replace my current rom with the WWE version which has less bloatware and takes it easy on the RAM.

Can someone kindly explain (or redirect me to a link) of how to downgrade HTC M8 from image version 6.20.502.5 to image version 6.12.1540.4 or in layman's terms how to replace AT&T rom with Developer rom? BTW both roms are Marshmallow. I do not wish to install TWRP or CM so if there is a way besides this I'd be grateful. If not then I don't see any other options and I'd still be grateful

Awaiting your generous replies
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
What you want is not really a "downgrade" per se. While the AT&T version number is "larger" than the Dev Ed (6.20 versus 6.12), that is mostly just because it came later due to AT&T's slowness in approving the software. I don't think there is much (if anything) that is actually "newer" or "updated" in the AT&T stock ROM (versus Dev Ed). It just has (as you know) all the AT&T branding and bloatware crap.

What is keeping you from flashing the Dev Ed RUU 6.12.1540 is that your carrier ID (CID) needs to match the RUU (even with s-off). Therefore, you need to change your CID to that of the Dev Edition (or alternately SuperCID), which is easy since you already have s-off. You will however need root to do this, so either flash TWRP and SuperSU/Magisk to root, or you can run adb shell with run while booted to TWRP. Either way, you will need to install TWRP: https://xdaforums.com/htc-one-m8/general/change-wwe-m8-to-dev-edition-ota-t2826567

No need to change the Model ID (MID) since the AT&T version and Dev Edition have the same MID.

After that, you should be able to run the Dev Ed RUU.
[One (M8) Q&A, Help & Troubleshooting] ckpv5:
Sorry .. correction. No need root/twrp to change CID, only change MID need these.

Simply reboot to bootloader/fastboot then run command

To Dev Ed CID

fastboot oem writecid BS_US001

To SuperCID

fastboot oem writecid 11111111

Can't remember if this only can be done on unlocked bootloader. If can't, try this command first

fastboot oem rebootRUU

the follow by the above.

If still can't then need a unlocked bootloader to proceed.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Ah yes, obviously I was mixing up my methods to change CID versus MID.

Thanks for clarifying, yet again.

Update

Good day all:

Sorry to bother again but it failed again! I downloaded fastboot adb and followed the procedure, put the phone in fastboot mode and the CID was already 11111111 and still it refused to accept the RUU. Please find attached a photo of my fastboot screen, hope it can help determine where the problem is on my phone. [ The following errors occurred with your submission:

On the official HTC site in the support section where they post the RUUs it states the following.

"Before you proceed, please confirm that this software upgrade to 6.12.1540.4 is a newer version than what is currently loaded on your device. If it is the same version, there is no need to reload the software. Navigate to the Home screen then tap All apps > Settings > About and locate the Software information . If your Software number is less than 6.12.1540.4 , you should proceed with the upgrade." end of quote

This paragraph is what let me to believe it is the software version that is stopping me from changing RUUs and why I called this post a downgrade (even though I know it's not)

Can any of you good gentlemen help me out a bit more? I'm willing to answer any questions to further clear the picture of my predicament.

Thank you again
[One (M8) Q&A, Help & Troubleshooting] ckpv5:
Bootloader is fine, still ATT.

Explain more on the error that you have when you tried installing RUU.

Do note - to run RUU you need PC with USB 2.0;

Latest htc usb drivers which you'll get when you installed latesr htc sync manager (uninstall sync manager but leave all drivers to proceed RUU installation)
[One (M8) Q&A, Help & Troubleshooting] Sir Lucifer:
Thank you for your reply:

the RUU I'm trying to install is the developer RUU that I downloaded off the HTC official website. It is the same website I downloaded the AT&T RUU from which installed fine, upgrading the phone's OS from Android 4.4.4 to Android 6.0.

I have several laptops each running a different OS (Windows 7 which I use mostly and have been using for this process) Windows 10, Linux and Solaris.

I did download and install HTC Sync but disabled it's auto run when I noticed every time I plug my phone in it pops up. So that's disabled not uninstalled, but it didn't interfere in the RUU installation of the ATT update and it doesn't pop up when I try to install the developer update.

The Error get is as follows:

Upon running the RUU it does all the necessary checks and then asks me if I would like to install the update, I click on "I Agree" and next, then it puts the phone in boot mode (black screen with HTC written in grey) and after it begins the process by popping up a screen that says: Current info about your Android phone: Image Version: 6.20.502.5 select one below and the update button. After I click on it another screen pops up: Verify that you want to update the Rom version from image version 6.20.502.5 to image version 6.12.1540.4 Clicking on Next another windows shows explaining what happens when I click on Next. When I click next it puts the phone in boot mode and begins by Reading header, sending............................................. then it pops another screen that says update failed and I have to click on recovery and press the power button on my phone for 10 seconds to turn it off
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
You can't really take the "official" HTC info literally, anymore. By having s-off and SuperCID, you are so far off the "official" path, that most of the rules no longer apply.

S-off bypasses version check (flashing older RUUs is allowed). In fact, you can RUU all the way back to Kitkat if you wanted with s-off (not recommended - just making a point).

---------- Post added at 09:56 AM ---------- Previous post was at 09:52 AM ----------

The RUU stalling out while "sending" is a common bug. Did you simply try running the RUU again? A lot of times, it will work on subsequent attempts.

The fact it got that far, means to me that it passed (or bypassed) any version or CID checks. Otherwise, it never would have gotten to the point of "sending". Instead, it would have told you something like "Error 140" with a description of what the problem was, and aborted the install before ever "sending".
[One (M8) Q&A, Help & Troubleshooting] Sir Lucifer:
Have tried it 5 times already, results are the same. I'm downloading the RUU again, maybe my download was corrupt. Will get back to you later with any results. Thank you for your patience and time. Much appreciated

RUU Broken on HTC's website

Dear all:

After downloading the developer RUU for the second time and trying to install it again (Marshmallow for those of you who have just joined us) off the HTC support site I failed miserably at changing my firmware using that RUU. After a series of searches on the internet and darknet I came across a post on reddit dot com titled M8 marshmallow RUU from HTC is broken and the article was dated last year. Searching further I found a similar post on a Chinese website that stated the same thing. So in conclusion the developer RUU on HTC's site is damaged as confirmed by a few users/developers on both reddit and the Chinese website.

Sorry for wasting all your time gentlemen. I am very grateful (and very lucky) having assistance from good people like yourselves who have taken from their time to help a complete stranger. Much obliged gentlemen. And thank you all again
[One (M8) Q&A, Help & Troubleshooting] ckpv5:
Cannot be the RUU is broken.

Another way to do this :

1. Install Dev Edition firmware. You can get the fw_6.12.1540.4.zip from - https://xdaforums.com/showpost.php?p=60218734&postcount=5

2. Instead of using RUU exe, you can use RUU zip (rom.zip) to install RUU. I remember long time ago someone had same problem like you. Asked him to use zip format RUU and it was successful.

I believe there is RUU.zip somewhere on XDA. Can't search now as I'm on mobile.

You can get your own RUU.zip which is actually rom.zip yourself. Just run RUU.exe (no need to connect phone). Once it opens the agreement page, go to %temp% thru your search/run windows menu.

It's better to clear your temp directory first so easy to find 2 newly created folder when you run RUU.exe

The rom.zip is inside one of the folder. Copy that to your desktop.

Then follow this on how to install - https://xdaforums.com/showpost.php?p=64926626&postcount=6

There are 3 methods but I prefer the htc_fastboot because easily can see any error if any.

So step 1 firmware & step 2 RUU (rom.zip)
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Did those threads specifically mention RUU 6.12.1540.4? If not, then you realize this device has dozens of RUUs for the M8? Most of which have been confirmed many times over to work properly.

My experience, is that 95% of the time, the problem with RUU running is with the PC. Try re-installing HTC drivers, different USB port, turn off USB 3.0. Also try a different USB cable, or if possible another PC.

Downloading the RUU again (as you tried) is not a bad idea. They do sometimes get corrupted while downloading. But if you download another time, and it still fails, the problem is probably not the RUU.

You should also verify your PC has Visual C++ installed, as the RUU exe requires it. The error your are encountering doesn't sound like the C++ problem. But it won't hurt to verify, anyway. Link here, but confirm it's the right install for your Windows version: https://xdaforums.com/showpost.php?p=60021580&postcount=4

Or of course, you can use the RUU.zip method stated by ckpv5, which avoids all the of the above possible pitfalls. You'll need to search for the 6.12.1540.4 zip, as I don't know where it is off hand, either.

Downloaded Again

I did download the developer RUU again, I also downloaded the Metro PCS RUU which has a software number of 6.20.531.5 and it installed just fine but refused to see the sim card so I reinstalled AT&T

I am an electronics engineer so yes my laptops are always up to date on flash, oracle, C++, Perl, Java, etc
[One (M8) Q&A, Help & Troubleshooting] xunholyx:
I have the RUU.zip

You can download it from here :good:
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
That is the T-Mobile RUU. MetroPCS merged with T-Mobile, so it's a bit one and the same. But most everyone will call that RUU/version T-Mobile. It will change band support (as flashing any other RUU will). So if it was working before on the AT&T RUU(or Dev ED will support the same bands) I would not mess with random RUUs, unless we suggest them specifically.

Hey guys,

for some week or maybe month, I'm having some kind of issue with my device and the home-wifi-router.

The problem: There are some kinds of webistes that just aren't working in my home wifi. I tried dozens of different browers all with the same result. Some pages that don't work are amazon.de obi.de and kicker.de and twitter.com

Same thing with the Amazon App and Twitter app. They just don't load any content - with mobile data on, it works out.

All of those pages and apps work out with other android devices and also in other peoples WiFi.

I also tried the secure mode, with the same result.

I've heard, that there might be an issue with ipv6, but, unfortunately I can't switch anything on or off in the router settings.

It's gotta be something about the router, but I can't change anything. Maybe there's a way to work around that with some kinde off app or something to turn Ipv6 off, IF that is the problem?

The phone has got stock rom, no root, no nothing. Maybe there is an opportunity with rooting? Warranty is expired, so there's nothing that speaks against rooting, if this might help. But then, I need someone to help me with all that - so far I only rooted an old nexus phone wia root toolkit.

Check your routers internet filter settings maybe something blocks your device . Also check your routers wifi settings if necessary turn it off and on again. Reboot your router or in worst case reset it BUT DON'T DO IT IF YOU DON'T HAVE THE ACCESS DATA.

Try to change the wifi settings on your device. Change from DHCP to static and see if it works.

Hello,

So I was using Greenify and hibernate Facebook app, but with the last week or so. My facebook app sometime doeasnt load, showing "cant connect right now" and I tried to search google. most issues I've found are Greenify's issue on facebook, especially when facebook got hibernated and woke up for a long time. I had to restart my device to getting facebook working again, ridiculous.

so any workaround on this? As we know that facebook app is the worst battery sucker.

I'm using Resurrection Remix 7.1.2 on Mi 5s Plus, rooted and privileged

Thanks.
[Greenify] DB126:
Best option is to use one of the 'lite' Facebook alternatives which preserve functionality without the corresponding hit on battery life and data consumption. Also make sure non of Greenify's alternative doze/hibernation modes are enabled (aggressive/deep/shallow) as they are known to create side effects with few, if any, corresponding benefits on Android 6 and above. Good luck.
[Greenify] x1ld3n:
I use greenify in shallow hibernation mode and Facebook works fine and doesn't eat much battery.
