not for that ;) have fun ..

btw. the "stock rom" is pretty old, and they didn't fixed the leaks like WLAN, BT security issues. so maybe you should take a look at the tweaked stom rom from Wonders Never Cease

https://xdaforums.com/one-a9/development/att-dev-rom-vvm-integrated-release-4-24-t3365326

or u just go for the latest LOS 14.1 , and if u want to use the HTC Launcher, you can get it from the XDA App.

Need HELP!

Where can I download developer unlocked CID-11111111 RUU file?
[HTC One A9] dusan116:
hello folks,

i bought a brand new HTC A9 from ebay, its ATT unlocked device. Been searching and doing attempts to upgrade to Nougat but with no luck. Also from the box, its 1.57.617.52 and when connected it want download an update 1.57.617.60 and once done it says We found different variant of software so we cant upgrade.

I guess i need a stock firmware for 1.57.617.52 or? and then upgrade to Nougat as from the thread i need new firmware first. Tried few versions and still no succesfull flash. Always got an error.

Can someone advise or post firmware that will work? SOme of the old links are down.. many thanks

Yes,I've used the RUU.zip in the OP but I can't seem to extract a .zip from the exe that I downloaded from HTC for 1.27.502.5 RUU.

I am new to this forum and in searching for step by step instruction on how to root the htc one a9. Is there anyone who can give a step by step instruction on how to do it? Thanks
[HTC One A9] alray:
Take a look in the development section, there is a thread dedicated for that with instructions (its off topic here)

Edit: here
[HTC One A9] crowsnestitsupport:
I have the unlocked A9 and used this method to RUU back to factory to get the latest OTA:

First, rename the RUU zip file to “2PQ9IMG.zip”, save it at the root of your external SDcard.

Reboot the phone in bootloader mode.

Now it will start scanning the SDcard and detect the 2PQ9IMG.zip file.

When asked “Do you want to start update?”.

Use your volume Up/Down key to start or cancel the flash.

Wait for the process to complete and don’t turn off your phone during the flash.

Worked perfectly for me.
[HTC One A9] AntikerTa:
I have done it so, too. And now i am waiting to the OTA. :laugh:

I have tried to install the Stock Rom with fastboot Command, but i get the Message that the File is too large.

Also i have do it with the SD Card Method. It is working perfect.

Hi guys,

How do you find the official RUU links from HTC (http://dl3.htc.com/application/RUU****)?

I'm asking because I need RUU files for HTC Nexus 9.

How do you use htc_fastboot. I put the htc_fastboot.rar in my adb folder but when I attempt to flash the zip using the htc_fastboot , terminal says ./htc_fastboot: No such file or directory. How do I do this properly. I'm using a Mac by the way.

[HTC One A9] theNdroid:
Okay so I had a rooted unlocked US ONE A9. I received the notification for the 6.0.1 OTA two days ago. However because I had a custom recovery and was rooted I couldn't just press "update", we all know it doesn't work like that. So I went on XDA looking for some help and I stumbled upon frago21p's thread titled "[6.0.1 Stock Rom] HTC One A9 Update From 6.0.0 (1.12.617.6) To 6.0.1 (1.55.617.4)". I followed his instructions and failed miserably and the troubleshooting steps he's been giving me haven't been explained very well and I have simply been failing. I am currently stuck and do not know what to do. I've tried to RUU but the RUU stops at 1% and says "Error 155: unknown error". I have no idea what this means. When I tried to use the RUU though my the RUUwizard says that my current ROM version is 1.55.617.4, because I flashed a firmware.zip from frago21p's thread, and the download is for 1.12.617.6, but when I try and boot my phone up I get sent to the boot loader screen with a *** init fs_mgr_mount_all *** error. I'm really lost and don't know what to do at this point. All I wanted to do was update from 6.0 to 6.0.1 . If anyone could provide any help that'd be wonderful. I'm thinking about calling HTC and getting my UH-Oh protection replacement but I'm hoping one of you guys have been in this situation before and have a solution for me.

Thanks in advance.

The real problem is I just bought this new phone and it keeps restarting itself randomly, I tried factory reset but it did not help. the bigger problem is I might have no warranty option for this phone so I want to try possible solutions to see if I can fix it. however I prefer to use official HTC rom which I have already downloaded one. any guide is appreciated.

Well if its new you should be able to send it for repair under warranty. Converting it to another version will requires S-OFF to change the CID and MID numbers

Riddle me this , ATT would not push me any updates on my A9. I have been stuck on the November security patch.I dled the RUU from the HTC website and I extracted the rom.zip renamed it. I relocked my Bl,saved the .zip to my external SD card and flashed the .zip.It was the 1.27.502.5 update(think that's right)number may be off with out looking.Everything went perfect it flashed like it was meant to be.The phone exchange booted up to setup screen except where I used to be able to select tools or next,tools is greyed out.So I press next on to the WiFi options,I have no option to skip so I enter my WiFi and connect.Next is Google sign In,It says this phone has been reset please enter the email you used to last sync this phone.Thats easy I've only used one email ever.I enter my Gmail and password,it says you are not the primary user please sign in with the primary users account for the phone.Now I have 2 step verification on and it's sent to my phone,I hear a message come but can't see it because I'm stuck on Google sign in with no skip option.I finally took my wife's phone put my sim in it just to verify my Google account,I ended up taking the phone to att,they couldn't even get Into the stock recovery,so I did another factory reset for them,after an hour of them fiddling taking my phone in the back,passing it all around they can't figure anything out and denied me a new phone because it was working when I left the store.So I bought the note 5,but I loved that HTC any suggestions how to fix it?or why it's telling me I'm not the primary user?Sorry for the long rant.

googles anti-theft 'Device Protection' since android 5.1 after factory reset. Google calls for last account data.

google for 'device protection' or If you get XTC-Clip you can change imei
[HTC One A9] alray:
If you do factory reset on phone connected to a Google account and you have a lockscreen set (password/pin/pattern), you'll have to connect to the same Google account after the factory reset or the phone will be locked. If you have made any changes to your account (like changing your password) you'll have to wait 72 hours before being able to use your phone with your Google account. You can avoid Device Protection by disabling your lock screen before doing a factory reset.
