Restore Stock 1.47.651.1 OTA Rom WITHOUT ROOT

There's been some confusion about how to get back to a stock rom without root in case you want to bring your phone back for warranty or return. First off this is basically this method is the first half of this thread from whitslack:
ttp://forum.xda-developers.com/showthread.php?t=715915
But the forum title is so misleading that when people do a search they will glimpse over it simply because it says it's to root the phone. However, only the second half of the instructions show you how to root it. So... here's instructions on how to do it.
1. Download the stock rom.zip. (For some reason I can't post links so you'll have to find it here = ttp://forum.xda-developers.com/showthread.php?t=728766&highlight=stock+rom
2. Rename rom.zip to PC36IMG.zip
3. Copy it on the root of your sdcard
4. Power Down or Turn off Phone - (Not Reboot)
5. Hold down Power and Volume Down (Let go when you see white screen)
6. Wait for HBOOT to scan for PC36IMG.zip
7. It will ask for you to accept after scanning - press volume up for yes
8. After finishing - it will ask to reboot - volume up for yes
9. You're done (Stock Unrooted)
Also, yes there is the RUU exe way and if that works for you, great! but there's a lot of people having trouble doing that and if you're here reading this you're probably one of them.

Just run the RUU for that OTA and you'll be back in stock.

That does not work for everyone, this always works.

I don't think this will restore the 1.40 PRI. Can anyone confirm / refute?

I thought this was just to get things back to stock. My WIFI does not work, nor does my facebook contacts sync.
so i don't have root and none of those work..lol wtfff

My PRI shows up as 1.34_003.

ruu for 1.47
I could not verify but when I use the 1.47 when I had wimax wiped out and it put a different MAC address.

Hi, thank you for clarifying. Was searching for some time for how to do this as I need to return my Evo to Sprint.
Do I understand that it's as simple as downloading the file, renaming it, let HBoot run it and that's it?? Really...100% back to stock?
Root will be eliminated, nand will be locked and my custom recovery method (Amon RA) also gone??
I have: (See attached too)

I used this method earlier this week and had my phone replaced by Sprint. It flashed back to stock recovery and Hboot.

What about all the directories in the root location of the SD card?
There's a lot of stuff there, i.e., nandroid, etc....

Which radio version is on the phone now? Is it Radio_12.41.60.19_26.06.04.14_M?
This is a quote from his thread:
"Using a "non matched" radio could have a negative effect on performance, battery life & signal strength."
Go to> Settings> About phone> Software version> and see what it says under Baseband version.

I am running 12.39.60.19_26.06.04.06_M

Bars mean nothing and are calculated differently between manufacturers and devices. Go by your db in settings about.

That might be your problem. You need to flash the proper radio and you should get better signal.

Thanks for all the replies. See my problem is I don't know how to flash the radio. Ive been reading about it but seems very difficult. I've come from the ios devices that was very easy, just install the newest software and your done no need to flash this or that. I think I read if you messed up on flashing your radio it can brick your phone. Not willing to go back to ios. Loving android at the moment.

Download the radio you need. It will probably be in a .zip, so open it in your favorite unzipper (I like 7zip) and pull out the radio.img file. Now go to the hack kit and find the radio folder. In the radio folder will be a PD98IMG.zip file, open this with 7zip, and replace the radio.img file that's currently there with the one you just downloaded (you can just delete the original from within 7zip, then copy/paste the new one), then close 7zip. Now redo step 5 from the hack kit (flashing the radio) and your new radio will be flashed.
If you feel comfortable that you understand this step, all you need to do is get your newly created PD98IMG.zip on your SD Card, boot to bootloader, then let HBoot start the update.

See I used the one click or step root. I don't think it was the hack kit. Anyways are you talking about unzipping it through the phone or computer?

Rooted and no HSUPA? Read this for my theory and a possible fix.

I think some of these rooting programs/routines like Bubby's root are causing the loss of hsupa. See my post here about it: http://forum.xda-developers.com/showpost.php?p=12828255&postcount=2961

I extracted the radio.img from the PD98IMG.zip file in the \ace\tools\dngrd\ folder from the hack kit. I opened it up in a hex editor and found the version - 26.03.02.26
You can download the radio in PD98IMG.zip form from here: http://wiki.cyanogenmod.com/index.php?title=Support_Downloads#HTC_Ace
So now we just need someone whose HSUPA is not working to downgrade to this radio and see if HSUPA comes back. If it does, then you can flash to 26.06.04.14 or 26.08.03.07 from the same link above.

I am thinking you may be onto something..........
I flashed the downgrade radio. Upload speeds still slower than before I flashed the stock radio. Now I am going back to the radio I had before stock and see what happens.

Maybe you need to flash the downgraded kernel from the hack kit as well? Does anyone know if that would even work - flashing the downgraded kernel on top of a custom rom like cm7 or mui?

worst case scenario, wouldnt it just prevent android from booting up? if so, you could always put the correct kernel on the SD cad and reflash it from recovery right?

Per the hack kit thread: http://forum.xda-developers.com/showthread.php?t=952352
I believe the kernel he links to in there is the downgraded Telus kernel: http://forum.xda-developers.com/attachment.php?attachmentid=518730&d=1297824204
EDIT: I believe its the boot.img in the hack kit in he \ace\tools\dngrd\ folder as well.

Before I went back to stock I was Uploading @ 1.50Mbps. Went to stock radio because of the ROM I am on and my Upload speeds won't go over .30Mbps. Using the downgrade radio didn't help. It was a good idea.

I had the exact same issue. Like I said re-rooting fixed the issue for me. I was thinking that loading the downgraded radio would fix it, but maybe you need the downgraded kernel as well?
did you confirm it was the downgraded radio in "about phone"

Yeah, that was the first thing I did. Check to make sure the radio flashed correctly. I have to go put the kids in bed now. I am pretty bummed about my new slow upload speed.

There has to be an easier way. I can confirm that HSUPA came back for me after the downgrade, before I rooted or flashed another ROM. I've looked through the hack kit and what gets pushed to the phone during the downgrade, there's not a lot of files in there:
android-info.txt
boot.img
hboot_7230_0.85.0007_101011.nb0
radio.img
rcdata.img
recovery.img
splash1.nb0
splash2.nb0
system.img
tp_ACE_SYN3KT0108.img
tp_ACE_SYN3KW020B.img
tp_atmel224_20aa.img
tp_atmelc12_20aa.img
userdata.img
We've tried radio.img and that didn't do it, m next guess would be boot.img, which is the kernel if I'm not mistaken. I am not sure what all the other files do specifically.

I like your dedication. We'll figure this out...

So this guy claims to have fixed the HSUPA issue simply by reflashing the downgraded radio: http://forum.xda-developers.com/showpost.php?p=11847379&postcount=17
Maybe it's because he flashed radio.img directly instead of the PD98IMG.zip method?

I see we are still trying to figure this out???

For a quick test, can you reboot the phone again? I know when you edit build.prop, most people say it takes two reboots for it to take effect. Maybe just for the hell of it, reboot a second time and then try another speedtest? It's probably worth a try.

Thanks. I got mine working but it involved going through the hack kit and losing all my data and then having to re-root and all of that. I'd love to find out what part of the PD98IMG.zip file fixed the issue, so that hopefully people can flash just that and fix their issue without losing data, re-rooting, reflashing ROMs, etc.
I am half tempted to purposely break my HSUPA just to figure out the fix but I'm not feeling that masochistic just yet.

Right now I am back to the stock radio and looking into some things. I will be back in a bit, hopefully with some info.

Cool good luck. I wish I would have caught you in time to try the second reboot. Maybe you will be brave enough to reflash the downgraded radio and then also do the downgraded Telus kernel?
I am going to read up on what all of these files in PD98IMG.zip do. Maybe the answer is in one of those other files.

So after reading up on the files some more, I now believe it could be rcdata.img, which has something to do with controlling the radio. I opened it up in a text editor and its a small file that contains a handful of line:
QCT_UMTS_RADIO_VER=1
DisH=2
HSDPACat=10
HSUPACat=6
QCT_UMTS_RADIO_END=1
That's the entire file. What I posted there is the one from the downgraded radio in the hack kit. Maybe this file needs to be reflashed in conjunction with the downgraded radio? In theory you could open up the PD98IMG.zip file that you downloaded for the downgraded radio, and then add the rcdata.img from the hack kit to the PD98IMG.zip file, and then flash PD98IMG.zip and it should flash both the radio and the rcdata.

Radio question.

I flashed my radio to (baseband version):
12.41.60.19U_26.06.04.14_M
I'm having severe issues with my connection.
I have 0 bars on some locations, where as an iPhone, or a non-smartphone, has 3+, or full bars at the same location.
Is this the radio issue, or is this the physical antenna of the phone being bad?

what rom you have?

I use that radio with saga and I get great reception. With stock I was getting -90 to -100 at home. I get - 70 now.
Sent from my Inspire 4G using XDA Premium App

Did you flash the corresponding ril?
I use that radio and got an average of 6 db better signal than I did with the stocker in south Florida USA.. I also use a gingerbread Rom. Btw never use bars to determine signal strength, its subjective at best. Go to menu,about phone,network to see signal strength.
I recommend reading the radio thread in the sticky under development. It's a great thread. Good luck to you.

simplest way for radio flashing
modified from Kirk's old post
1. Download this file http://www.megaupload.com/?d=BX5GV1CJ
this is a zip file containing two files. one is radio.img from ATT stock radio, dont touch the other file (android-info).
you need to remove this img file and replace with the Gingerbread radio.img
from here http://www.multiupload.com/BE0V4H8QQY
extract the radio.img and zip into the PD98IMG.zip with the other file (android-info) already in the PD981img.zip. (two files)
2. Place the PD98IMG.zip radio file on the root of your SD card.
3. Power the phone off, remove and reinsert the battery.
4. Hold the volume button down and press power on.
5. The phone will boot into Hboot then Bootloader, It should see the PD98IMG.zip and ask if you want to apply the zip.
6. Use the volume up button to select "yes"
7. Once its done flashing, reboot the phone and you should have flashed the radio.

Try reflashing your radio using this method:
http://forum.xda-developers.com/showthread.php?t=1002226

I've had major issues with my GPS and from what I've been reading, reflashing the radio could help. I dl'ed the pd98img, placed it on the root of SD, booted to hboot but it never finds the file.
Any ideas as to what might he goin on? Fwiw, it takes about 10 minutes to go through all the steps till I can reboot back to os.

HTC Noob Question about Radio Flashing

I've seen devs mention to flash a radio from Hboot and Fast boot before. Are these terms synonymous? Fast boot is accessed from Hboot correct? I've flashed a radio a few times, but never understood the terminology. A PD98IMG is always flashed the same way from what I understand.

More or less correct. HBoot flashing is done with the PD98IMG.zip on the SDcard. PD98IMG.zip can contain any number of images to be flashed. Fastboot flashing is done using the fastboot.exe and can flash a single image.

I've never quite understood what the advantage is to fastboot flashing. Then again, I've never truly understood fastboot in general.
Something I definitely need to do more reading on.

I've tried several times, and several methods to flash my radio to the 12.54.60.25_26.09.04.11_M2 radio img. And nothing seems to be working. My best guess is its user error. I'm a noob and trying to learn how to flash my radio. I currently have the 12.39.30.19P-26.06.04_M with the TPGB-Ninja_0618 ROM and [email protected] #28 kernel.
I've done the method where i go into adb to access bootloader, then i flash the radio.img then reboot the phone and that doesnt work. I've tried running the radio.img though CWM and that didn't work.
If I power off my phone and then hold power and -vol down to get into the bootloader it automatically will go into hboot and start to run through the PD98IMG.zip. I'm wondering.
Do I need that .zip folder on my sdcard forever or can I get rid of it?
Also, can I just switch out radio.img in the PD98IMG.zip with the new radio.img?
Can I do the above question without having all the other .img 's in the .zip folder?
I've done some research, but haven't found my answers, or was able to fix my problem.
So hopefully someone can help me.
Please be gentle with me, I'm new to this type of thing, but a fast learner.
Thanks in advance

Assuming the PD98IMG.zip containing the radio flashes properly, you can remove it afterwards.
Have you checked out the inspire only radio thread in the dev section, yet?
There's already a ready-to-flash PD98IMG.zip for the radio you want to flash on that thread.
Download it from that thread, verify the MD5 checksum, plop it in the root directory of your SD card, reboot into hboot/bootloader, once it finds the PD98IMG.zip, confirm the update, and away you go.

Ok I'll try that as soon as I get to my computer. Thanks for the reply and I'll let you know how it goes.

Couple of things. 1) Be sure to give the radio long enough to "warm up"...I'ave had it take several hours after flashing before I started getting decent speeds from a radio I know works. 2) It is usually recommended to keep a copy of your radio flash on your SD card in case you need it (GPS fail, etc., ) so you can reflash if you are away from a PC, but not keep it in the root of your SD. It's very possible to end up in a continuous boot loop until you somehow either get the file off your root (SD card reader) or fool the phone into thinking it isn't there by pulling the SD card when you pull the battery to recover (I've only heard the last trick works)...

You've also made sure you have the appropriate RIL for the new radio you flashed, correct? That radio thread also has the RILs + info about them, as well.
Also try rebooting more than once after flashing a radio/ril, just for good measure.
When I first flashed the 04_11_M2 radio, I had only rebooted once, as a result of the flashing process. Once my phone was done loading up, I received my first call with it, the caller couldn't hear me, but I could hear them. Caller tried calling back. Same thing. I decided to give it another flash and reboot. I called that person back, and it was working, never experienced that since.
Coincidence? Who knows? But radios are weird, quirky things that seem to need a little "voodoo" type flashing/rebooting to kick them in, I suspect.

Well I think I found out why I'm getting these speeds. My radio has a "P" and not a "U" like in meiguoguizi's sig. I have the same radio as that (number wise) but he has a "U" and not a "P".
The radios that I can flash have an "x" in that place so won't that just mean it will switch to whatever letter my data is running on?

I think I found out why I am having this problem.
I can flash the radio.
I can flash the RIL.
But I have a "P" where the "U" is supposed to be to represent the HSUPA speeds.
If thats the the reason then I don't know.

I think that U/P thing is determined by one of the settings in the build.prop file. I know it's been discussed before, I just don't recall the details. If you visit the "editing the build.prop file" thread in the dev section, or possibly amongst the comments in the inspire radio thread, I think you might find the specifics in one of those places.
Or browse through henrybravo's posts, I think I remember him explaining it to someone.
Bottom line is that you have the same radio, it's just a setting that's determining the connection type and as a result, that letter changes, depending on that setting.

First, try another re-flash of the radio.

I did a full wipe and restore and got all the sounds back. Reloaded the RIL and everything works fine.

Yes the x is a placeholder (remember your algebra).
Open he's right. You have to flash the Riley that goes with the radio and then reboot twice. Make sure you are using the best radio for your Rome.
