[Q] Downgraded HBOOT - no ROOT possible?

[SecUpwN]

Wanna earn a free hug and a huge thump up on XDA? Then solve this riddle:

I successcully downgraded the HBOOT of my friends HTC EVO 3D GSM to 1.49.0007 using the Ultimate Recovery Tool. Thing is, I had to soft-brick the system first to downgrade the HBOOT and now, after the downgrade and automated unbricking) I obviously can't gain S-OFF. Why is that? Well, his phone wad previously been repaired and got a new motherboard, thus I cannopt unlock via HTC-Dev. And since I have no working Android system to boot into, rooting via Revolutionary doesn't work either (stopped at waiting for device). What to do now? ALL (good) HINTS WILL BE REWARDED!

Can you flash a ROM? Is your bootloader locked?

Thanks for your attention. The phone of my friend does not have a working recovery nor system to boot into and is still S-ON.

Did you try flashing RUU exe as stated in Ultimate Recovery Tool OP?

Nope, I don't own a winblows computer. Is there a way to do that on LINUX or even MAC?

No, I don't own a winblows computer. Is there a way to do that in LINUX or even MAC?

I think you can push recovery via fastboot with Linux. I never used anything but Windows so I'm not sure

Of course, but without ROOT this results in a signature error. Any other solution?

Try to find stock recovery, push it via fastboot and then try RUU

 

[SecUpwN]

@donkeykong1, thanks so far, I'll give this a shot ASAP. Is it possible to RUU via Recovery, ADB or fastboot? As I said, I own several LINUX servers and some MAC machines, no crappy winblows.

If you can run exe. file on LINUX or MAC you should be able to run RUU

Have you ever used LINUX? Dude, I've googled for hours to find the STOCK RECOVERY for the phone of my friend, but it seems like this thing is hiding! Could you help me out to find it? You'll receive another thump up. Here's the setup:

* HTC EVO 3D GSM
* HBOOT 1.49.0007
* RADIO 11.25.3504.06_M
* OpenDSP v02.6.0.2226.00.0202

Are you able to find the correct stock recovery image? Flashing other recoveries results in "FAILED (remote: signature verify fail)".

No, I've never used LINUX
Try to open your RUU exe file and see if there's recovery image. If there is, extract it and push it to your phone

Open the RUU.exe? No way to do that. Sh*t, I just need this freakin' stock recovery..

 

[TeChNoC4AzY]

Hmm.

Sent from my PG86100 using XDA Premium 4 mobile app

 

[SecUpwN]

Hmm.

Right. Any other things I should try?

Maybe you can get it with a PG86IMG.zip.

 

[donkeykong1]

Maybe you can get it with a PG86IMG.zip.

I thought of that too, but couldn't find RUU zip

 

[SecUpwN]

Awesome idea! Can you find the correct one?

Here's a list of RUU downloads. Some of them are also available as zips.
Maybe you can find your desired recovery img there.

Edit:
I do also use linux (ubuntu).
In case of none of the zips is the right one:
I remember some time ago (rather long time ago) I pulled some files out of an ruu exe.
I've been running a win xp img in virtual box for doing that.
Just run the ruu exe and look for the extracted files in tmp directory.

I guess you need ICS europe. That .zip file is corrupted. I doenloaded it for you the other night but couldn't open it (bad file)
