I have Sprint HTC A9 with CID 11111111 and MID 2PQ930000, can you please suggest me to install an unlocked international ROM?
[HTC One A9] alray:
What frequencies are supported by your service provider? The Sprint A9 doesn't support all the frequencies supported by the GSM variant. Afaik, youll have to reflash the sprint radio and rfg partitions after a conversion using another ruu than sprint...
[HTC One A9] DakshFella:
Dialog Uses the frequencies as below,

GSM - 900 (E-GSM)	GSM / 1800 (DCS)	GSM

UMTS - B1 (2100)	UMTS

LTE - B3 (1800 +)	LTE / B40 (TD 2300)	LTE

I've re-flashed with Sprint 2.18.651.2 RUU and Sprint 2.18.651.2 Firmware, now I'm getting a message which says Simlock Enabled, This drives me mad :(
[HTC One A9] Dragonkind:
You can change your MID to 2PQ912000, then flash 2.18.617.30. It's the US-unlocked version.
[HTC One A9] DakshFella:
I have done it, but I'm only getting 2g signals with that, I do not get 3g or 4g. That is where I was stuck and flashed back the Sprint ROM

Can you suggest me any way of getting 3g and 4g with US Unlocked ROM? I'm living in Sri Lanka and using Dialog SIM
[HTC One A9] Dragonkind:
Strange… I also face the similar issue, my A9 came from China, I flashed it to Taiwan version but it still doesn't show "4G+" with Asia-TW RUU in Taiwan. Everytime I flashed RUU it would show radio.img written. However it always doesn't have "4G+" icon on status bar.

So I'm not sure if I have the method to solve it, if I have, I'll share with you!
[HTC One A9] alray:
GSM/GPRS/EDGE: 850/900/1800/1900

3G UMTS: 850/AWS(1700)/1900/2100

4G LTE: FDD 2,4,5,12,25,26 TDD: 41

I think you should be able to get 3G. Make sure your APN is correctly set (check with your provider). Afaik, LTE will not work (see above freq.)

[MENTION=4654136]alray[/MENTION]

If I simply flashed the firmware zip, I don't need to flash ROM.zip or full RUU before installing latest stock-based ROM, right? The firmware equals to "RUU without system partition"?

ps. The version number of your topic title seems to be not correct, it's 2.18.617.30 the latest.
[HTC One A9] alray:
True when the firmware.zip was extracted from a RUU. If extracted from an OTA update, it's most likely incomplete (only partitions to be updated are packaged).
[HTC One A9] samweli benjamin:
I have attached my getvar all information, my a9 sprint is modified i want to bring it back to unmodified and update to Nougat so i need help on how to update the firmware manually. Please show me how to go through:crying::crying:
[HTC One A9] samweli benjamin:
Can you please give me the link where i can download 2.18.651.2 firmware zip and the 2.16.651.2 RUU.exe , please help....
[HTC One A9] alray:
Flash the firmware first then flash the ruu. See post #2.
[HTC One A9] alray:
Links are at post #1
[HTC One A9] Phone_fan:
If I extract the recovery from the firmware zip using 7-Zip, will I be able to use it to flash in Fastboot?
[HTC One A9] alray:
absolutely
[HTC One A9] Phone_fan:
With S-On? I can Fastboot flash a TWRP recovery with S-On, but the headline for the firmware zip downloads said "only for S-Off".
[HTC One A9] alray:
S-off is needed to flash this firmware since it is not signed. If you only want to flash the recovery partition with the recovery image from this firmware, you only need an unlocked bootloader.
[HTC One A9] Phone_fan:
Need the RUU zip for 2.18.617.30 Firmware

I'm trying to restore my Unlocked US A9 and need an RUU zip to do it. My A9 last had 2.18.617.30 Firmware on it when I unlocked the bootloader and flashed TWRP.
[HTC One A9] alray:
The .exe is at post #1, you can extract the rom.zip from it:

Launch the ruu.exe

Wait for the InstallShield Wizard to extract the files (done when you can see the "Welcome to rom update utility" window) do not close the rom update utiliy or the temps files will be deleted

Go to your local temp folder (Windows Key + R then type %TEMP% and hit enter)

start a search for "rom.zip" and copy to your adb/fastboot dir

You can now close the rom update utility and flash the rom.zip to your phone.
[HTC One A9] alray:
Update on .exe ruu

After verification, it looks like HTC removed all*** Marshmallow executable RUU (ruu.exe) from their download server. Only Nougat executable RUU are accessible. Expect to get a 404 error when clicking download link of post #1.

Dead link .exe RUU list:

1.57.617.60

1.57.617.52

1.57.617.32

1.57.617.20

1.56.617.1

1.55.617.4

1.12.617.6

1.60.651.4

1.57.651.1

1.09.651.1

I guess they really needed that 20GB space occupied by these files......

*** The Marshmallow executable RUU for AT&T is still online (obviously since there is no nougat for at&t)
[HTC One A9] Phone_fan:
Wow...it worked! I had completely given up on my A9 because I tried so many things and nothing worked. Thanks to you and your help, my A9 is right this moment restoring the Google backup from the last time it was used.

Much appreciated. If you have a PayPal account, I'll make a donation...

[HTC One A9] 47captain:
I know it, man. My only problem is : the main version firmware 1.27.xxx.xx I can't find the version. (Hboot)
[HTC One A9] alray:
The only thing you need is the 1.27.709.5 ruu from post 1
[HTC One A9] 47captain:
Yes, 1.27.709.5 Ruu is available but this ruu's firmware (main version or hboot version) are not available. Therefore not me flash Marschmallow RUU (12 RU_ZIP_ERROR). I need firmware 1.27.709.5
[HTC One A9] alray:
The firmware can be extracted from the RUU using the RUU decryption tool made by captain_throwback and nkk71.
[HTC One A9] 47captain:
thanks,my problem solved.

I have another problem,

my phone occasionally shuts itself down again, it opens.

have you experienced this problem before? I don't know why.

[HTC One A9] alray:
instructions are at post #2 and links for sprint ruu are at post #1 under "HIA_AERO_WHL"
[HTC One A9] alray:
If this is happening after successfully flashing a ruu it's most likely an hardware problem.
[HTC One A9] Nuroxy:
I dont know how to use Ruu Decryption Tool. Can someone share 1.57.617.60 firmware.zip ?
[HTC One A9] alray:
If you can use adb/fastboot you can use the decrypt tool, its not harder.

https://xdaforums.com/chef-central/android/tool-universal-htc-ruu-rom-decryption-t3382928/amp/

Take the time to read the first few posts, there are instructions with examples.
[HTC One A9] JohnRogers23:
It is my opinion that if you can't extract what you need to flash then you really shouldn't be messing around with your phone in the first place. Please read more, you'll break something.

Need 2.18.707.1 rom for a9 or something compatible

Hi

I soft bricked my phone,was trying to install lineageOs 14.1 09/05 nightly on Indian A9-which was updated to Nougat in April.

I only got bootloops.

I have unlocked bootloader , but S-On.

Firmware is 2.18.707.1

I can boot in twrp recovery or download mode etc.

Tried 2.18.617 ruu which is available online, but got error 155, which said -to use compatible rom.

Wasted a lot of nights trying to solve the issue.

Could not find compatible firmware.

Kernel etc for the same firmware has been released by Htc like 3 months ago on htc dev.com

Please help. I think 2.18.707.1 ruu will solve the issue. Or please suggest any other rom or solution which may work.

More over , I was experimenting on my wife's phone.:D

Missing RUU - MID: 2PQ910000, CID: VODAP102, v 2.16.161.5 It is released and many phones are OTA updated.

My A9 crashes and has bootloop, relocked and S-ON - no OS, no recovery, so I could not unlock, could not flash, so my only solution is SDcard method with original RUU MID: 2PQ910000, CID: VODAP102, v 2.16.161.5

Can anyone help me find the RUU file?
[HTC One A9] JochenP:
i searched without success. If nothing helps you can use XTC2Clip to unlock and s-off your device (able to flash any rom).

You can also send me your device and i will do this for you.
[HTC One A9] slawa:
This worked for me too. Thanks!

Otherwise I would have been stuck and would have to go s-off.

Same here. I am very unsatisfied with HTCs slow updates.

And then they also did not release the sources in time. Which killed custom roms for this device as all devs moved on and did not come back. Just look at Xiaomi Note 3 Forum. Tons of ROMs. This here is a graveyard.

This was the last phone I bought from them. They will die as a company. Google just stripped them of all talent and now they will ride it out until all cash is gone. RIP

Hi

I hope someone can help me and i apologize in advance if ive done anything wrong or posted in wrong section, I have a htc a9 which belonged to a family member and was nearly thrown away before i aquired it. It keeps bootlooping to and from the htc logo screen. Ive gathered some information from it

It seems to be on nougat 7.0

Os - 2.16.206.5

I have tried flashing a few ruu's with the sd method but fails. Please can you point me out to the right direction in which ruu will work on this as i do not have a clue. I believe there is a firmware and ruu zips.

All help is much appreciated and im sorry if ive posted on wrong section

Thank you

I don't which ruu you have tried to flash but if you read carefully post #2 you'll see that there is no RUU in this collection that will work on your phone. You must flash 2.16.206.5 or newer (not available here). Unless your phone is S-OFF you'll have to buy the RUU from a website like this:

[HTC One A9] Otaku-San:
Sadly, yes. There is no other method to S-off without paying 25€

Hi friends! Can I make a S-OFF on the smartphone HTC A9 Sprint? If so, which method is suitable? Thanks!
[HTC One A9] alray:
You can use Sunshine S-OFF or an XTC 2 CLIP in direct mode.

Sunshine is cheaper (25$) and easier to use unless you already have(or know someone) with an xtc 2 clip (100-200$)

Sunshine will only work for the device it was purchased for.

cannot flash ruu

Hi there,

thanks for this collection.

I tried to upgrade my HTC A9 from 1.56.401.81 to 2.17.401.2 by flashing using my sd-card. The phone was s-on but the bootloader was already unlocked.

First I placed the 2.17.401.2 firmware on my sd-card with the name "2PQ9IMG.zip". Then I entered the download mode, pressed volume-up as instructed by the screen and flashing started. Now, it doesn't seem like I would be able to proceed. The phone only turns on when pressing power + volume-up, it will show the white HTC screen for a moment, reboot and show the white screen again, now not responding any further. At this point, I'm only able to press power + volume-down so the phone powers down, again rebooting first and finally actually shutting down. Does anyone know how to flash the ruu in this case? I'd really appreciate help.

Here is the output of the getvar command in fastboot:

(bootloader) kernel: lk
(bootloader) product: htc_hiaeuhl
(bootloader) version: 1.0
(bootloader) imei: undisclosed
(bootloader) version-main: 1.56.401.81
(bootloader) boot-mode: download
(bootloader) version-baseband: undisclosed
(bootloader) version-bootloader: 1.0.0.0000
(bootloader) mid: 2PQ910000
(bootloader) cid: HTC__034

Edit

I figured out how to proceed correctly. Apparently, download mode cannot be entered normally in this case. To flash the ruu, one has to boot using power + volume-up, wait for the reboot so the white screen permanently appears. Then, I pressed power + volume-up for the phone to restart, and immediately upon vibration press volume-down to get into download mode.
