Now that Alpharev has come out with new sized Hboots, there is a new one called a downgrader. There doesn't seem to be an explanation for this. I flashed cm7r2 before and I would now like to go back to Stock. Do I flash the downgrader before I flash the Stock? What happens to a nandroid backup of a cm7r2 rom? If the Stock Hboot flash does not go as planned, will it still restore?
The new hboots are like locked and no matter what, if you use an RUU, the hboot won't be overwritten, so therefore to use one you need to use the downgrader so you can use an RUU.
The backup will be on your SD card.

used alpharev hboots and now when i run ruu it bypasses hboot and leaves phone s off , i would like to go back to stock do i need stock hboot?
anyone has it?
cheers
download "bravo downgrader" from alpharev.nl flash it and then the RUU
You need to flash the bravo_downgrade hboot first, because the new r2 hboots by alpharev are locked, so they cannot be overwritten.
Swyped from Oxygen
than you guys , i tried doing that but my usb on pc was playing up so did not flash it . after restart worked a threat
been trying different roms today and couldnt get mms to work for any so i reverted to stock as i need mms
i have flashed cm7/r2 Hboot . can i return to stock Hboot . how i can do that safely . thank you
there should be no problem, just do it the same way you did flash cm7
only thing is you have to flash also a rom(sense ones) that needs stock hboot,
else you have to much system but to less data space.
but i would suggest you to try "Insertcoin Cm7" Rom, one of the best Sense Roms out there. So you dont have to switch to stock again.
best wishes
ps.: always do nandroid backups!

You need to flash the downgrader file first and then the stock hboot.

Only when you flash the hboot by ruu or ota. If you flash stock hboot by alpharev, you do not have to flash downgrader. But there won't occur any problem when one flashes downgrader first.
i have downgrade the cm7r2 hboot to stock, flashing before the downgrader and then the stock hboot. but it's remained the version of cm7r2 hboot (6.93.1002).
Hi. I am currently using Supernova Rom but want to try Runny 3.5. I was thinking I would use a completely new memory card for Runny so I can leave my current memory card untouched (thought this would be best because Supernova uses Data2SD). I will obviously perform a nandroid backup.
1. When going to CM7r2 hboot for Runny is there a way to backup my current hboot to flash when going back to Supernova? Am I correct in saying the hboot is modified when you s-off so to remain s-off if going back to Supernova I can't just flash a stock hboot or I will be s-on?
OR would I have to go back to a stock RUU ROM and root and s-off again and then restore nandroid backup?
2. What exactly does a nandroid backup backup on your phone? Does it backup hboot and kernel?
Thanks
In response to my own question. At http://alpharev.nl/ is says if you are already s-off just flash a hboot from the website so would this be "Bravo Stock"? Also when flashing CM7r2 hboot will I remain s-off?
If you flash a different hboot, you will remain s-off. This will not put you back to s-on. So you could flash CM7r2 try any amount of rom's you wanted, then flash a different hboot and try a rom that requires that hboot. You will remain s-off unless you flash a RUU.
A nandroid backup will backup your kernel and everything on your phone at the time of backup.
Hope it helps.
Thanks. Seems reasonably simple then. I will probably have a look at Runny tomorrow i reckon.
I had alfa rev Bravo Stock hboot, but update to Bravo CM7 r2
How to back to Bravo Stock hboot?
May i download Bravo Stock hboot, rename it to PB99IMG.zip and upade current hboot?
1) Nandroid backup in recovery.
2) Verify the MD5SUM of the file you downloaded against the one in the table.
3) Flash HBOOT with your phone in fastboot mode (Back+POWER) -> 'fastboot flash hboot bravo_alphaspl.img' (change into the correct filename for the HBOOT you downloaded)
4) 'fastboot reboot-bootloader'
5) 'fastboot erase cache'
6) Boot recovery, wipe everything and restore

Can I do this:
You can also download the corresponding PB99IMG zipfile, put it on your sdcard, and rename it to PB99IMG.zip. Then start the phone in HBOOT mode (VolDown+POWER) to flash the HBOOT without a PC. It is however still necessary to either restore your nandroid, or reflash your ROM after doing this.

Think you'll need to fastboot flash the AlphaRev downgrade hboot as the newer hboots (CM R2, OxygenR2 etc) are downgrade protected.

You only need to use the downgrader when you want to return to factory S-ON. Otherwise, leave it alone.
I use this

Or to use one of the original CM/Oxygen partition tabs. My bad, didn't realise there was a protected stock alpharev tab (been a while since I use _thalamus custom tool these days)
I have BravoC, but in this thread http://forum.xda-developers.com/showthread.php?t=1483919, will my BravoC brick if I flash with only CM7r2 or all Alpharev HBOOTS? Some of Custom GSM's Rom have CDMA patch and I want to try it savely.

All hboots will brick your device.

hboots are for GSM devices only
if you want to install a custom rom like this one:
http://forum.xda-developers.com/showthread.php?t=1403113
you need to use cmtd to change your partitions like an hboot will do for a GSM device
follow these instructions:
http://forum.cyanogenmod.com/topic/23984-guide-to-installing-cmtd/
after rebooting recovery flash the rom followed by the CDMA patch and GAPPS
then flash the boot-cMTD.zip
reboot
hopefully you found one with a patch that actually works
Hi,
I didn't realy downloaded much rom these last few years, so just to be sure : when a rom require a stock hboot, it just requires the default partitionning, right ? So I just go to alpha-rev and download the default S-OFF one ?
Thanks
Yes. However, if you have never changed hboot, then you are already on stock hboot and you won't need to do anything.
If you do need to change hboot to stock, use the first one in the table "Bravo Stock" with 250MB /system
You need to check which hboot you're on currently, as you may need to flash the Bravo_downgrade.img from the same page first.This will unlock certain write protected hboots, so you can then flash the stock hboot over the top.
I always recommed to flash hboots using fastboot
