ok where do find them or how do i make them i have zip seiner on my phone. i have just flashed a bunch of radios and prl files. i thought this was supposed to be easer that we could even flash kernels and such.
[Hero CDMA Android Development] 24601:
Oostah, here's the android-info.txt file you need. Zip this file with the .img file you want to flash and name the zip HERCIMG. But, hey man, be careful flashing radios. Flashing the wrong radio is the one thing that can brick your phone.
[Hero CDMA Android Development] oostah:
Im running a 2.32.40.11.09 Verizon radio and a evo prl now. I'm on alltel and it was the only way I could get my phone some what usable. So I heard s-off would have made it easy.thanks alot for the help and the file can I use this with kernels and and other thing.
[Hero CDMA Android Development] 24601:
Like regaw says, "This allows you to flash an ***.img file to a specific partition on your phone without making a zip. You can also make a HERCIMG.zip (a zip with multiple images in it ie, system.img, data.img, boot.img, recovery.img) and flash that straight from hboot." But, I'm not a dev, so I'm not gonna tell you what you can and can't flash. I have flashed splash screens, radios, recoveries, and RUU's from hboot.
[Hero CDMA Android Development] oostah:
so that im right i take the radio.img and the txt file zip them two to gether. take out the manif files.
[Hero CDMA Android Development] oostah:
ok any img file they no where to go. or do they need to be ziped with the txt file for any and/or all img files
[Hero CDMA Android Development] 24601:
Take your radio.img file and the android-info.txt file and zip them together with whatever zipping process you have. Name the zip file you just created, HERCIMG.zip and that is what is flashed in hboot. Hboot knows what to do with what it finds in the HERCIMG.zip. I have no idea what you are talking about with a manif file.
[Hero CDMA Android Development] oostah:
if you extract the radio from 2.42.whatever.zip the radio.img is in there and a meta_inf file. i got the file wrong last post. but i understand just dont want to mess up with the radio:eek:
[Hero CDMA Android Development] 24601:
You don't need the meta-inf file to flash with hboot. Just the .img and the android-info.txt.

thanks a bunch for teaching me something new. and you time.

Flashing back to 2.x clockwork and eng-spl hboot, is it possible going back to latest clockwork with engspl or must i keep old 2.x vs 3.x cuz of dif hboot?
[Hero CDMA Android Development] il Duce:
You can go back to 3.xxx.

after flashing should i see S-off anywhere?
[Hero CDMA Android Development] laie1472:
Power down your phone. Then hold volume down+power. When the white screen appears look in the upper right/left corner of your phone. Should say S-off.

[Hero CDMA Android Development] 24601:
OK, I know I must be brain dead, but I'm stumped. I had to replace my phone this weekend and after using darkknight's rooting method, and installed CWM recovery 2.5.0.7 through rom manager, I am trying to go back to stock recovery.img so I can take phone back to Sprint. I was going to install darkknight's RUU 2.31.651.7 HERCIMG to get the stock recovery, so I used this method to get 1.46.xxxx s-off. Bootloader read the HERCIMG fine, then when installing img's, first it did not flash the boot.img; then after installing radio.img the phone blinked back to the bootloader screen and I was back to 1.47.xxxx and s-on, and went back to reading the HERCIMG, which it did, but, of course, would not install any imgs because security was on. What steps am I missing? Is there a better way for me to skin this cat? I want to go back to the stock recovery.img. Any guidance is appreciated.
[Hero CDMA Android Development] il Duce:
Go to my links thread and use jasonmaloneys unroot link, you could also try the exe, not the zip, also in my links thread.
[Hero CDMA Android Development] 24601:
Thx duce, do you mean ninja's using fastboot with eng - spl? I'll look at that. I'm using a MAC, so no exe for me :mad: Also, I don't have the flash_image binary on my system. Where might I find this? Thx.
[Hero CDMA Android Development] il Duce:
Adb has that.
[Hero CDMA Android Development] 24601:

If I understand what you're saying you can extract the recovery.img from the HERCIMG.zip you'll have the stock recovery. Make a new HERCIMG.zip with the recovery.img and android-info.txt.

[Hero CDMA Android Development] 24601:
Yeah, I looked at that. I have HERCIMG's that have 2.31.651.7 as the main version and 2.31.651.7 :11 as the main version. Both have worked in the past. Neither works using ninja's method. Now, this morning, I can't even get darch's eng-spl to take. It acts like it takes when I flash it but when I return to bootloader it still says s-on with 1.47.xxxx :confused:

I have a recovery.img from nfinite's 2.31.651.7 thread. Can I just zip it up and flash it through recovery?

Just got back into the Android scene with my Rooted CDMA Hero200 and was wondering if you guys could give me some more info on this SPL for the Hero and what it does exactly,I use to have a G1 with T-MO so I am pretty Android-Savvy if ya know what I mean. Any help with the radio is great too, I'm already rooted,running CyanMod7 Nightly with ClockworkMod Recovery. Wasnt sure if I absolutely should flash these radio and SPL's or not.Not sure if they are absolutely needed. Any help is greatly appreciated guys!
[Hero CDMA Android Development] il Duce:
This spl unlocks your bootloader, there is another method as well. The radio will likely provide better reception. Links for that stuff can be found in a thread I started, click my name.

[Hero CDMA Android Development] PS4AndroidHacker:
Would I flash the SPL or the radio first onto the phone,I have went through your post's on this topic and just couldnt find if I should flash the radio or SPL first. Thanks in advance again! - OK,Flash them and everything went great! The phone updated the Radio,then I went about updating my SPL,everything went smoothly and my reception here in this specific area of Ohio has just gotten better! Thanks to everybody for all your help!
[Hero CDMA Android Development] oostah:
is there a way to push this to the phone to get it working.

everything from fastboot shows an singniture error if i can get this to push and work i think i can get back up to full
[Hero CDMA Android Development] METHOD1911:
If I'm correct just flash this through recovery. I have hboot 1.47 and radio 2.42.01.0427. I'm trying to unroot my hero.
[Hero CDMA Android Development] laie1472:
Ha, sup meth. Hope all is good. And yup your good to go. Just flash. But you have to have Ra or Cwm2.5

If it still does not work after flashing a new recovery, try this file to RUU.

ENG-SPL.zip
[Hero CDMA Android Development] rjmohit:
Thanks a lot! :)

This doesnt seem to be a flashable zip though, how do I use it? :confused:
[Hero CDMA Android Development] jasonmaloney:
It should be flashable in fastboot.
[Hero CDMA Android Development] rjmohit:
And how exactly do I do that? :confused:

I have a doubt 'fastboot flash hboot hboot.img' would work. :-/

Am I right? Or any other way? :)
[Hero CDMA Android Development] jasonmaloney:
Rename the zip to HERCIMG.ZIP and transfer it to your microSD card. Reboot into Fastboot and it should prompt you to flash.
[Hero CDMA Android Development] rjmohit:
That didnt work :(

Maybe coz the zip is not signed? :confused:
[Hero CDMA Android Development] Hippie459MN:
Here ya go. This is the original file from the first post. I have a habbit of keeping files around just encase. lol

http://www.hippie459mn.com/downloads/heroc.hboot-1.46.2000.zip

If I remember right just flash from recovery.
[Hero CDMA Android Development] cytherian:
I have instructions that say this should be done via fastboot. I went to perform it and got the following result:

sending 'zip' (163 KB)... OKAY

writing 'zip'... INFOsignature checking...

FAILED (remote: 12 signature verify fail)

I downloaded several other ENG-SPL zips from other sources, all roughly the same size files, and still had the same result. I've seen mention of the need to verify md5sum and I did that to make sure that the zip files weren't corrupted.

I also tried to install the zip file from TWRP and it failed verification there as well. I'm really stumped...

UPDATE: Just in case anyone else finds themselves in this same scenario, here's how to solve it:

Install ROM Manager again, flashing the ClockworkMod Recovery and then rebooting into Recovery. From there, select the ENG-SPL.zip file and install it. This will replace the bootloader. Reboot into the bootloader to verify, then do a normal system reboot. DONE. :)
[Hero CDMA Android Development] Hippie459MN:
cytherian, we didnt have TWRP back when this was posted so that might have something to do with it. All we had were CW and RA back then so I am guessing thats why it worked with CW. Just a guess. :D

Glad ya go it working though.
[Hero CDMA Android Development] cytherian:
Yeah, when you get into rooting and custom ROM flashing, there's bound to be some things that remain a mystery because the programs developed to do the functions hide a lot of the complexity involved. But then when things don't go quite right, one can get seriously stuck (and thankfully the forums are a terrific venue to get advice/assistance).

I figured out how I possibly got hboot 1.7 installed on my machine. At one point I installed a later version of ROM Manager (5.x), which must have flashed that bootloader into place. Because before that I had installed version 1.3. TWRP doesn't touch the bootloader, so it left whatever was there in place. Thus, I had to find a way to replace that bootloader. All of the manual methods just wouldn't work. If there's one thing I must say, it's a thumbs up to ROM Manager for its brute force methods. After I got the bootloader with S-OFF in place, it was easy to get TWRP back in place.

Anyway, I assume that if I applied an RUU (like 2.27.651.5), I would have gone completely back to stock with an original bootloader, and that would have worked as well. But that brings up this cross operating system issue of backups. From what I understand, TWRP doesn't function under 2.1. So, I'd have to install ROM Manager again, flash a base 2.3 ROM, then install TWRP again, THEN run one of my TWRP backups. Tedious, to say the least. ;)
[Hero CDMA Android Development] Hippie459MN:
Yeah, I am S-Off with like hboot 1.47 or something. Cant remember off hand. I was always on RA recoveries and never tried running a 2.1 rom when on TWRP. I was on 2.3 when I flashed it. I wounder if it has something to do with older binaries that might be in the zip files that dont work with TWRP. I dont know. I know the newest TWRP (2.3.0.0, just released a few days ago) for our Heros uses a new binary to check zips that is different then 2.2.0.0 so most these old zips wont work with it.

Anyways, Glad ya go it working. :D
[Hero CDMA Android Development] cytherian:
Did you ever come across a technique for updating the PRL without having to go back to a stock ROM? That would be the only reason why I'd ever go back to stock... so I'd like to get around this. Thanks!
[Hero CDMA Android Development] Hippie459MN:
I have not updated my recently and dont even know what the latest is off hand but I know this is one way you could do it. I have done it this way before it it worked great for updating it but its been a long time.

Yeah, I tried that one before, with echoing "1" to a system or dev folder (there are two different ones I've seen mentioned) but it didn't work. I have no clue why not, because there's no error message. It just echoes a hash prompt. I tried running it via a command shell in Windows and in terminal emulation on the Hero. No joy.

The latest is 60690. It's attached in THIS thread. :angel:

I think you posted in the wrong thread, as this is for hboot. Nonetheless this is what you are looking for.
[Hero CDMA Android Development] zachslavin:
Well Darch if my noobie ass opinion means anything--I can't wait to hear more.
[Hero CDMA Android Development] HeroMeng:
Does this enable flashing a custom splash screen (as in the HTC screen that comes before your rom's bootscreen)?
[Hero CDMA Android Development] darchstar:
I'd actually say the exact opposite.Its actually a great tool for newbies to just test out stuff without making nandroids after nandroids. everything is temporary with fastboot. it only lasts for one session. so in case of flashing kernels, you can test if it'll boot on your phone, or if its right for you, then go into recovery and actually flash the kernel for good without having to hassle with nandroids. same applies for a lot of other stuff in android modding that could potentially make a n00b think they bricked there phone. Its a safety net is what im trying to say. I'd recommend for everyone that wants to root to flash an eng spl
[Hero CDMA Android Development] HeroMeng:
I used it to flash a splash screen from the GSM hero portal and it worked just fine. Thanks Darch!
[Hero CDMA Android Development] codejunkie78:
darch, is this just for the sprint hero, or will this work on all heros? and if i use this will I still be able to use my carriers ruu after using this?

[Hero CDMA Android Development] HeroMeng:
The one I'm currently using is attached. To get it to work, you need the engineering spl, adb, and fastboot. Unzip the zip below, you should get herosplash.nbh. Don't copy it to your sdcard, you don't need to. Then, run adb shell reboot bootloader and it should load into fastboot. Then, run fastboot flash splash1 herosplash.nbh and your splash screen will be the skateboarding Androids.

Sorry if this is really stupid, but when you talk about using fastboot to run a file for one session, how does that work? Is this something we can use for those on aosp to fastboot a sense rom and update prl, and then reboot phone back to our aosp without nandroid?

Just flashed this over hboot 1. 41. 000 and everything went perfectly. This upgraded my heroc to v. 1.46.200. Now if I got this straight, if for some reason a RUU was necessary there would be no need to root again? Darchstar, thank you for all your hard work.

[Hero CDMA Android Development] kyouko:
Awesome :D been waiting for this to be released.
[Hero CDMA Android Development] LiquidSolstice:
I still can't, for the life of me, understand this.

Am I correct in relating this to an Ubuntu LiveCD? Enabling the ability to boot into a ROM without Nandroiding, and having all traces disappear on restart?
[Hero CDMA Android Development] PlagaDeRock:
From my understanding it unlocks the bootloader. The bootloader has till now always been locked so if you upgraded you cannot downgrade from an official ruu. The bootloader is also the thing that your phone first sees when it opens up, so essentially if something goes wrong you can fix it before having to get to the recovery. I think.

That might be a little rudimentary but I think I got the basic principal right. As far as always having root, I'm pretty sure as long as your bootloader is unlocked basically your phone is unlocked so if you flash a ruu and there is no root you don't have to wait till a root is found you can flashback to a rom with root or something else. It doesn't mean if sprint released a 2.2 today and you flash it you'll have root, it just means if you flash it you can go back which without an unlocked bootloader you wouldn't be able to do. :)
[Hero CDMA Android Development] LiquidSolstice:
But I've been able to use the Sprint RUU to downgrade already (from *.6 to *.5)
[Hero CDMA Android Development] regaw_leinad:
This does NOT give you root, it allows you to flash images to specific partitions (among other more advanced things), so you could just flash a custom recovery from hboot, instead of getting the flash_image binary on your phone, then flashing it there. BUT, I think this will get wiped out if you RUU. Just an fyi.

That was a special case, I still have NO idea why it worked to downgrade it. Everything is set to NOT allow it to downgrade, but it still does. We got lucky, that's about it.
[Hero CDMA Android Development] PlagaDeRock:
It makes sense to me lol.
[Hero CDMA Android Development] pwrmedia:
+1 to what he said. Flashes via hboot are session-specific, meaning you'll need to Nandroid if you like what you've flashed during that session. IMO, the best perk w/ what we've got now w/ unlocked bootloader is the ability to "test" different kernel setups w/ different ROMS w/o the tedious task of reflashing, wiping, etc. Thanks again to you guys for doing this!
[Hero CDMA Android Development] duffkitty:
Ok last question before plunging in. If the flash goes awry is there a recovery method? I know a nandroid won't work but even if its run the official ruu that's a good enough failsafe.

Same goes with a custom splash... What if..
