There is much confusion regarding whether it is possible to successfully convert Boost Mobile/Sprint HTC One A9 to Unlocked/Developer version.

Many have tried before by changing the MID and CID and flashing the Unlocked/Developer RUU but have had issues with missing IMEI, random reboots, and general instability.

I can confirm that is is actually possible to do the conversion and also fix the missing IMEI/random reboots.

Prerequisites:

S-OFF

Bootloader unlocked

Sim Unlocked (See my post here for free sim unlock method)

What this fixes:

No mobile data (but have voice/sms) on sprint firmware after sim unlock

Missing IMEI/random reboots after Unlocked RUU flash

My device specs:

(bootloader) kernel: lk

(bootloader) product: htc_hiaeul (was previously htc_hiaewhl before conversion)

(bootloader) version: 1.0

(bootloader) max-download-size: 1164800000

(bootloader) slot-count: 0

(bootloader) current-slot:

(bootloader) version-main: 2.18.617.1

(bootloader) boot-mode: download

(bootloader) version-baseband: 1.1.U40062.1@61214 (Sprint radio)

(bootloader) version-bootloader: 1.0.0.0000

(bootloader) mid: 2PQ912000

(bootloader) cid: 11111111

1) Follow this guide here. I flashed the updated Unlocked 2.18.617.1 RUU from here instead of the older RUU linked in the post. The RUU version should not make a significant difference.

2) After the RUU is flashed, the device will reboot. It is optional to wait for the device to finish the initial boot. The device will not be in a usable state as the IMEI will be missing, radio won't work, and have some other critical bugs.

3) Reboot the device into bootloader mode (not download mode!).

4) Download the Sprint radio here (extracted from 1.60.651.4 RUU)

5) Extract radio.img and run

fastboot flash radio radio.img

6) reboot the device. Your sprint/boost mobile a9 should now be working on T-mobile or your GSM carrier. If your carrier bands are supported, you should also be getting 4G.

You may also be able to flash CM14 on your converted a9, but I have not tried it yet.

Have a happy new year!

Followed the instructions up to the radio flash. (bootloader) HOSD CL#680768. FAILED(REMOTE: 35 RU_PARTITION_NOT_SUPPORT radio)..... Any suggestions ?
[HTC One A9] jianC:
You need to be in bootloader (fastboot) mode, not download mode.
[HTC One A9] Mrpoy13:
GOT IT ! Thank you so very much ! I have been hoping on this for a year.... Love this phone and didn't want to give up on it.

JianC ... You saved my a9, awesome work ! Its working perfect !

data works well over 4g, but I can not make voice calls

Hi, I followed all your steps because initially after unlocking the sim, dont work the network data but the voice and sms works fine on 1.60.651.4

After putting the nougat version (2.18.617.1)

And restoring the radio.img, the data works well over 4g, but I can not make voice calls. Shows network unavailable.

Also in nougat I can not install twrp to be root

My phone is a boost mobile 2PQ93 and I am in an operator that handles band b2.

I can use only 2G on my a9 sprint after flash RUU Nougat 7.0 dev edition and flash Sprint radio :(
[HTC One A9] Formedras:
Does this modification break compatibility with Sprint networks?
[HTC One A9] CRasH180:
Good question. I would like to convert my phone to the Developer/Unlocked model of the HTC One A9 and am currently on the Sprint network. I would like to know the answer to this as well

Got back from HTC an unlocked A9 instead of the Sprint A9 during RMA, and WIFI calling is missing, along with the ability to update the profile. Also the unlocked phone is unmanageable online, have to call Sprint to do anything related to the phone.
[HTC One A9] Formedras:
That doesn't say anything, really, since the CDMA A9 is physically different from the GSM versions with regards to the radio.
[HTC One A9] syntenza:
wanna give it a shot but would like to know if it's possible to reverse back if anything goes wrong? i'm missing the right LTE band here where i live :/

btw [MENTION=5422071]jianC[/MENTION] where you already in Nougat firmware before flashing RUU? i see a warning mention on alray's post!
[HTC One A9] hoang555:
Takes phone to Da Nang, I will unlock the network and fully convert it to Unlocked Edition.

pm if concern
[HTC One A9] jianC:
I cannot guarantee that it is possible to revert. I directly flashed from unlocked Marshmallow firmware to unlocked Nougat firmware.
[HTC One A9] syntenza:
can i flash from sprint marshmallow to unlocked dev marshmallow? don't wanna try nougat yet.
[HTC One A9] nonamett:
[MENTION=2230378]jjan[/MENTION]C can you extract Sprint radio from Nougat Sprint RUU, thanks!
[HTC One A9] Zero_Lord:
Im downloading the RUU from the first post but it marks a error "132 Signature wrong" something like that, what I can do?

Also when I flash the RUU from the tutorial thread I got invalid sim message. When I flash the sprint radio I got a ok message but when I reboot I have the same radio. So I don't have any clue...
[HTC One A9] imtawakkal:
is it just me or even after got sim unlock and reflash radio.img, im just getting 2g networks only? never get the 3g, before the conversion and update, i still can get 3g networks :(
[HTC One A9] st40611:
After lots of tweaking around, I finally got it!

The key thing is that radio.img wasn't the only thing needed; radio.img will get you LTE (in the case of T-mobile), but not 3G/WCDMA connections (which is why many people that have no LTE can't even get 3G.)

I ended up doing the following (S-off still of course, and follow all steps instructed in the OP):

1. Download Sprint firmware from here: https://www.androidfilehost.com/?fid=673368273298932288

2. Extract it, and you should see many files, but the key files are: rfg_1.img and rfg_2.img

3. Reboot to bootloader mode

4. fastboot flash rfg_1 rfg_1.img

5. fastboot flash rfg_2 rfg_2.img

See if this works! If not, I did some other steps, but not sure if relevant:

- fastboot erase modemst1

- fastboot erase modemst2

- fastboot erase cradio

after restart no sim card

followed your steps and 3g worked but one day after restaring the phone it says no simcard
[HTC One A9] st40611:
Yeah, I realized after my post that you need to wipe modemst1 and modemst2 every single time. You can also install a Terminal app and wipe it with the following command (provided you have root):

su

dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1

dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2
[HTC One A9] brukyoung:

I managed to get this work outside the US. I (re)flashed all the original sprint radio config partitions (modemst1, modemst2, radio, rfg_0, rfg_1, rfg_2, rfg_3, rfg_4 and rfg_8, so not just the ones is some firmware update) after conversion, and everything is working fine.

[HTC One A9] idarph:
If firmware is 1.x use and older twrp like 3.0.2.x, if 2.x use 3.1+

---------- Post added at 09:57 AM ---------- Previous post was at 09:27 AM ----------

Permanent fix:

1. Install 1.09.651.1

2. Insert SIM. Unlock SPC. Reboot, test success until it starts without locking the SIM. Link to method is in the op.

3. Install 1.57.651.1_R2

4. Install every other update from android: Setting-> About -> Software updates. This will upgrade to 2.18.651.2.

5. Root the device: twrp + magisk.

6. Backup partitions

adb shell
su #grant rights to user on phone
cat /proc/emmc #take note of mmcblk0pXXX mappings to partitions: rfg_0, rfg_1, rfg_2, rfg_3, rfg_4, rfg_8, radio, modemst1, modemst2

For each partition noted before issue a command like this, where XXX is the number of the mmcblk:

dd if=/dev/block/mmcblk0pXXX of=/sdcard/rfg_0.img

Now the created parition images can be saved to your pc/mac/whatever. Might be you have to disconnect/reconnect phone to see the files or use adb pull ...

7. Install 2.18.617.30

8. After install and setup complete, android is running, restore the original images:

adb reboot bootloader
fastboot flash rfg_0 <path to rfg_0.img created in step 6.>
fastboot flash rfg_1 <path to rfg_1.img created in step 6.>
fastboot flash rfg_2 <path to rfg_2.img created in step 6.>
fastboot flash rfg_3 <path to rfg_3.img created in step 6.>
fastboot flash rfg_4 <path to rfg_4.img created in step 6.>
fastboot flash rfg_8 <path to rfg_8.img created in step 6.>
fastboot flash modemst1 <path to modemst1.img created in step 6.>
fastboot flash modemst2 <path to modemst2.img created in step 6.>
fastboot flash radio <path to radio.img created in step 6.>

9. Reboot

[HTC One A9] fk2106:
can someone share all the radio, modemst and rfg files?
[HTC One A9] sin23:
Yes please...share all files ,i think is works if we flash all that files...
[HTC One A9] idarph:
I think that would not get you anywhere. I did this on multiple phones. For some reason all needed its own backups (or i messed up somewhere in the process to think so).

To flash unsigned zip-s you need s-off i think.

To create backup of the partitions you need root.
[HTC One A9] sin23:
Give me that files please,i have s off,i want to flash to se if is working,same phone same files....i think is working.please give me zip with files ,please please :)
[HTC One A9] fk2106:

I have the same problem.

I have LineageOS running and everything is working except I'm limited to 2G (signal icon says "E").

I'm on T-Mobile and I made sure to set my APN.

Any help?

EDIT: I briefly saw it jump to H+ before tumbling back down to E. It's possible that my work has a weak enough signal that it causes issues. Although my Moto e4 was getting LTE no problem

EDIT 2: Even outside my work building, it gets 2G only.

Help needed......

I am trying to go thru the motions to start this, but am getting quickly stopped out when trying to use the Basic Flasher.

1) Dial ##3424# then choose DM ON , I get prompted with the MSL.

2) Once I load the Basic Flasher, it comes up with a .NET Framwork window, so I decided to Update but to my dismay I am still having the same issue.

Beside the Scan button that would list the ports, it's completely blank. All of my drivers are working because I have Unlocked, Rooted and S-Off'd with the

Command windows just fine. When I hit connect it tells me to "Please Scan Ports", and when I do that it says "No Devices Found".

Has anyone come across this issue, and how does one fix it? I might be new into the world of unlocking and modding phones, although my last ATT HTC One A9 was a breeze to unlock

and convert to the Unlocked/DEV version...had it not dropped into a bucket of water while washing my car some months ago, I would still be happily using it.

I don't know if anyone has a video or is willing to help me out with this issue, I am just trying to get the phone unlocked so I can use it with my local carrier in Canada.

Any Help and/or direction would be MUCH appreciated.

My phone cannot connect to my Network, RUU is rock solid without any stability issues minus the fact it can't connect to the Network (Voice/Data).

I am not prompted with any strange "SIM LOCKED" alerts or anything, has anyone else come across this issue?

Had I known this phone would have posed such a ball-ache, I would have just purchased another ATT/GSM variant which took no time to get up and running.

I am very politely asking for some help and willing to donate some $$$ for someone's help and guidance here.....

Kiki.G, I finally got it working last night with flashing all of the Files that were posted in the bottom of that article.

The only issue I seem to have is when I reboot the phone, I have to go into Settings>Networks to sign onto my Carrier....and

that takes quite a bit of time. Other than that, phone functions normally and glad to be rid of any attachments with Sprint/Boost.

I did have to get someone else to perform the SIM Unlock, because I couldn't get it working.

Unfortunately, I have already done the conversion to the Unlocked/DEV Firmware....so I can't go back and Flash the Sprint RUU and get a

copy of my Radio.

I have another device I need to perform the same Surgery on, so perhaps you could help me with the SIM Unlock and then I would follow this protocol of

backing of the files from my own device.
[HTC One A9] Kiki.G:
Glad you succeed, I probably roll back everything three times until I done it right. Now it works great without any Issues on stock, unfortunately not so on LineageOs.
[HTC One A9] TheBosZ:
You can roll it back to the sprint firmware and get the files, I was able to.

Unfortunately, I have issues with LineageOS where it won't connect to anything faster than 2G (and I really don't like Stock HTC stuff) so I'm back to using my Moto e4.
[HTC One A9] 2low4snow:
Are you able to tell me how to do the Rollback?

Also, my biggest beef is how long it takes to get service after a reboot...I wonder if this would resolve the issue.

I've been using it (Making Calls and using Apps all day, no issues whatsoever)
[HTC One A9] Kiki.G:

You have to backup all your original sprint radios and then flash unlock rom and then flash all your original radios backups of the sprint rom, then you will have a permanent fixed even with OTAs.
