Root Radio partition borked? Please help!

[temuryusuf]

I am at a loss of things to try with this Evo which I have no history of.

After initially being stuck at 4-triangles. I managed to flash the ENG 0.76 bootloader. Found out that:

S-OFF
Radio: 2.15.00.09.08 -some sort of Chinese radio?

I've tried it many different ways with RUUs, fastboot and PH36IMG, but RADIO_V2 repeatedly fails to flash.

I can also flash any recovery, but it fails to load, getting stuck at the Evo splashscreen, so that is also a problem. Most partitions flash nicely in fastboot. A successful system flash will result in a stuck Evo splashscreen, though.

Is there any way out of this? Perhaps by using one of the elevated commands in the ENG bootloader? I don't know how to get ADB running either, since I'm stuck in fastboot and have no idea whether USB debugging was on earlier.

Any help would be greatly appreciated. Thanks!

it should be PC36IMG.zip make sure that you have it set exactly or it will not recognize it to flash

ok you need to slow down first of all. we need to know where exactly the phone is at.
1. we need to know what your hboot is?
2. and i have never seen this radio version 2.15.00.09.08. where did you get it?
3. so what exactly did you do first to get you in this state?
4. and like argedion said the file needs to be named PC36IMG in order for the bootloader to recognize it.
5. and lastly you said you cannot get into recovery? it just bootloops?
6. but you can get into the bootloader, correct?

Thanks for the replies guys.

PC36IMG- typo, sorry.
I have absolutely zero history of this phone. None whatsoever.

1. ENG 0.76. I received the phone with no access to the bootloader, stuck at the HTC screen with triangles in each corner. I flashed the ENG 0.76 hboot via fastboot and that's what I'm on right now. Works fine.

2. I have no idea. Google leads me to a thriving Chinese EVO forum.

3. Not a clue. I got it from a friend this way, who got it from an auction in Burma.

4. Typo. Flashing any radio in hboot will result in [see attachment]. Flashing in fastboot- see 2nd screenshot above. Fails either way, and I've tried multiple radios. Tried under multiple hboots, too. No dice.

5. Correct. Stock or custom recovery will flash fine but will get stuck at the white splashscreen if I try to enter it.

6. Yup. Works like a charm.

The only idea I can come up with is using an elevated command in fastboot oem which could reformat my radio partition somehow. I don't know whether I have ADB either. I do have a Linux box, so diag mode can be done. Have some experience with JET on the HOX.

Any ideas?

1. first off the four red triangles is means that it is in ruu mode. did you try and run a ruu at that point (before you downgraded your hboot)?

2. which ruu have you tried?

3. is this a us version of the evo 4g? i still can't find your radio to match up with any of the radios out there that was offered for the evo 4g.

also if this is what you did:
[GUIDE] HBOOT 2.10(.02 -?)[</3] Got you Down? - Get 0.76[<3] Back!

did you read in the big red letters as far as what hardware version you have?

in case you missed it, here it is:

If you're doing this on late hardware models 003/004 (with new partitions) then you should stop reading now and probably not do it. I'm not sure if the new recovery can fix up your stuff after you do this

edit: if this is what you did, then your phone might be bricked

Of course. That was the only option I had anyway since there was no accessible hboot to fall back upon. 4.54, 4.67, 4.53. Radio_v2 fails every time.

So apparently this is one of the radios used in China for using the EVO 4G with CDMA UIM cards. They then proceed to hardware mod the phones with UIM slots- I have one of those slots.

I don't know whether that should cause a radio to not flash on a NAND level at all. It shouldn't really.

Sorry, should've made that clear earlier.
