Rooting 32B Magic 'Perfect' SPL, whilst ensuring it can be returned to stock

First, thanks for taking the time to read this. I appreciate that these forums get a lot of frustrating posts with people asking questions that have already been answered, and it is not my intention to do that. I have been lurking on these forums for a while, and have read around quite a bit of information. However, I cannot find the exact answers I am after.
To start, I am now on my 2nd HTC Magic 32B (Voda UK), after I sent my initial phone off for repair. I was running Cyanogen Mod on this phone, and flashed this rom by fastbooting in to Cyanogen's Recovery and going from there.
I was careful to take a nandroid backup before I flashed, and as such, when the time came to said the phone off for repair, I was able to restore the backup and send it off with the stock firmware running.
Unfortunately, the phone I have now received has a 'perfect' SPL, HBOOT-1.33.0007, so I cannot flash a rom using the same method.
My primary concern through all of this, is finding a way to flash roms such that I can revert everything back to normal if the need arises.
I have read around 1-click rooting, so, my proposed method at the moment would be:
1) use Flashrec to boot into Cyanogen Recovery
2) Backup using nandroid
3) using adb shell to flash Cyanogen Recovery
4) use Cyanogen Recovery to flash rom
I should now be in a position where I can a) flash back to the original recovery if needed, using the backup from nandroid, and b) flash back to the original rom if needed, using the backup from nandroid.
Would this work as I hope?
I have read about having to 'downgrade' the SPL when wishing to restore a nandroid backup, but I did not need to previously. What are the circumstances where you do need to? - I would not want to do this, since I have no way of flashing the original SPL back. I presume there is no way to backup my SPL? so I could return to it if need be?
Thanks for taking the time to read this, and I appreciate any help you may be able to give me.
Cheers.

I have a Rogers 32A that had a Perfect SPL (1.33.0010) on it and I got a rooted recovery ROM by using One Click Root. The Perfect SPL wasn't allowing me to fastboot at all (giving me a "no access" error or something). So instead I booted running the stock software, and used the one click root program to backup my ROM and then flash a recovery ROM (used the default Cyanogen Recovery 1.4). Then when I rebooted while holding down Power + Home, I came right into my rooted recovery ROM where I could install whatever .zip ROM I wanted (AFTER I BACKED UP WITH NANDROID, of course).
I didn't need to use ADB for anything, and I still ended up with root. So I guess I'm confused when you say you're going to use flashrec to boot into cyanogen recovery and then use adb shell to flash cyanogen recovery. I was under the impresion that flashrec FLASHES cyanogen recovery for you, eliminating the need to use ADB/Fastboot. Assumed "flashrec" stood for "Flash Recovery ROM".
My steps were:
1) Install/run flashrec
2) In FlashRec: Backup your current ROM
3) In FlashRec: Select a new recovery ROM to Flash (has Cyanogen's by default, can change to something on your SD Card)
4) In FlashRec: Flash the Recovery ROM
5) Exit FlashRec and reboot into Recovery Mode (Hold Home and Power)
6) You're done, you have a rooted phone. Go ahead and Nandroid a backup, wipe your data, and install a new ROM.

Thanks for your reply.
It is my understanding that flashrec does not flash the recovery rom, but just allows you to boot to it. (Similar to the fastboot boot filename.img command). I would guess that if you reboot your phone using home + power now, that it would boot to the standard recovery.
If it is the case that flashrec does flash the recovery image, then that would be handy, and presumably the backup could be restored using either nandroid or adb.
Thanks, this clarifies that my rooting procedure is along the right lines, however I am still concerned whether flashing everything back to normal will go as I expect.

Just booted into recovery, and its still CyanogenMod v1.4 + JF.
I'm trying to think if I did anything special during my rooting efforts. I don't think I did. I know that I flashrec'd twice. the First was with Amon_Ra's recovery console, and then I did it again a bit later with Cyanogen's. But I'm positive I was never able to successfully use adb's fastboot command due to my perfected SPL.
And you're right, I didn't address your concerns about unrooting at a later date. I assume that is what you're doing when you use flashrec to create a backup of the stock Recovery ROM, but i'm not positive.

Taken from:
http://www.ryebrye.com/blog/2009/08/16/android-rooting-in-1-click-in-progress/
EVERY TIME YOU REBOOT YOUR PHONE INTO NORMAL ANDROID IT UNDOES WHAT YOU JUST DID. Every time android boots, it reflashes the recovery partition with the default one from a file stored in your phone. For safety reasons, we are not replacing this file – just flashing the partition directly. So if you boot to recovery mode, then boot back into your normal mode, and then boot back into recovery mode – you will see a triangle with an exclamation point and only 3 options.

So I'm not sure what's going on.
Thanks for your input. I think I'm nearing enough confidence to go ahead and give this a try. Probably tomorrow.

Hi ParanoiaPersonified - can you post an update when you flash? I also have a new Voda Magic with the same SPL as yourself.....I got the OTA upgrade to Donut yesterday which I may have been silly about accepting.
I wasn't too impressed with the speed improvements in Donut and now want to flash something built by one of the XDA chefs, but am having problems rooting with the traditional methods - even 1 click doesn't seem to work....
Cheers.

It is my understanding that one-click-root only works on 1.5, and the exploit that it uses is patched in 1.6. I think you may need to use the 'gold card' method, radita.
I've realised that my handset has a fault (the scrollwheel does not work when scrolling to the right), so I will be unfortunately waiting for a replacement handset before taking any of the steps mentioned above.
Hopefully the replacement does come with 1.6 pre-installed!

"Gold card" method looks a little more involved....guess I don't have a choice though.
Thanks.

[HELP] Stuck at HTC logo after installing bacon on unofficial CMod

What I did
1. Install unofficial CMod
2. Installed baconbits
Problem after bacon bits install on unofficial CM: i boot up the phone but it gave me an error/popup for every application i was running "google voice has encountered an error" "com.android has encountered an error" etc etc. endless popups to where i couldnt do anything on the phone other than locking and unlocking it.
what i tried to do to fix it:
3. Wipe data/factory reset
4. Tried applying Stock Recovery, thinking it would somehow help
current problem: stuck at HTC logo
please help! i just want to get it back up and running, any rom... rooted or not. i cant even get into the phone

Wow u really messed up.
Idk how to truly guide u out of this because it seems like u really don't know what ur doing. But your going to have to restore the phone. Read the thread about unrooting and returning to stock.
Also if I'm not mistaking you can fastboot flash system.img and data.img from pc10img.zip but as I said idk 100%
And flashing stock recovery is a no no because it can only read htc zips so it will block you out from flashing a new update.zip

Can you get into fastboot? Power the phone down and hold VolDown+Power.
Flashing baconbits over a non-official CM 6.1 was a mistake.... Baconbits is just an addon for a stock rom... CM 6.1 will have everything that baconbits has and more...

yes i can get into fastboot. problem is finding a htc signed rom... i think

If you are still S-OFF, you can flash clockwork mod recovery using fastboot and then just boot into recovery and install whatever rom...

i love you, no homo

just out of curiousity, how did u install that cm rom? if u used clockwork like it required, all u had to do after u messed up flashing bacon, was wipe, and restore, or reflash the rom again. why did u flash a stock recovery?
Sent from my T-Mobile G2 using XDA App

did a wipe, stuck at htc logo. didnt know i could just flash the cm file with clockwork... thought i had to use the clockwork rom manager when the phone is booted up. flash stock recovery, for some reason, i dont know. cried for an hour. called tmobile, had them send me a replacement. now on the phone telling them to cancel first android phone so im a noob, be kind

Can someone help me please?

My phone won't get passed the t-mobile mytouch 4g screen. This happened after I backed up my stock rom using rom manager and did a full wipe to start clean ut no after I went back and restored my backup, my phone is stuck on the mytouch screen and won't get pass that. Is my phone bricked? or can it be saved? can someone pls help me? I just got this phone yesterday and rooted it with no problem. All I did after the root was add a custom kernel. Everything was going great until I restored my backup. Pls help. Thanks in advance.

try going into the bootloader. press power& the volume down button at the same time. then let it load, select the option to boot into recovery. once u do that wipe all cache, data, and restore the backup u made. but if it doesn't boot up again then it might be a defective backup. might have to start fresh with flashing a new rom. but keep trying once u boot into the phone tho. goodluck!

I tried that and still not working. Is there away I can get a stock rom to flash?

Now I can't even boot into clockworkmod recovery. Now it boots me to the stock recovery. How can I get clockworkmod recovery back? I can't flash a rom without it.

The phone still says s-off so I don't know what is wrong and since I bought the phone yesterday I can take it back to t-mobile to get a new one but won't they notice the s-off and not exchange it?

Use Fastboot. It is like adb, but only uses the bootloader on the phone. If you don't have the SDK installed, you can get adb and Fastboot from TrueBlue_Drew's thread in the dev subforum.

Is there an official update.zip I can probably apply through the stock recovery?

Thanks Jaylito and Jggimi for your help, was able to get into cwm recovery and flash a new rom. It looks like I had a bad backup. Thanks again to you both.

(What if?)how do you recover from a boot loop on nexus4?

Hello everybody! I have a nexus 4 since a couple of months, and I had a Samsung galaxy s before. With that phone if you got stuck on a boot loop and couldn't access recovery, you used Odin to save you..what if it happens on nexus 4? Flash original image with a tool? Or there is some recovery file I can flash? Or what?
Thanks!

It's highly unlikely that you won't be able to boot into the recovery anymore on a nexus device as the recovery is pretty much "flash once, forget forever".
Meaning, you normally don't mess with the recovery partition.
If you, for whatever reason, really can't access the recovery anymore, you can flash a new one through the bootloader using fastboot.
fastboot flash recovery recovery.img
Should be the command to do so. Just check the tutorials around here.

What he said, and also should be noted that if you do backups of your roms, if you ever upgraded the recovery (say TWRP) you may wish to re-do a backup after you upgrade with the recovery option checked (or don't use it at all) since I've run into a situation once where I backed up my original stock on 2.4.4.0, and when I restored it, it downgraded my 2.5.0.0 to that, didn't cause problems just some options went bye-bye until I reflashed the recovery from fastboot (and just made sure to make a flashable-zip of just that recovery just in case).
As long as you can get to the bootloader on an N4 you can do just about anything to bring your device back to life, even if it's something like erasing the userdata, then formating /data in the new recovery because *cough*me*cough* stupidly flashed a galaxy nexus recovery from goomanager.
PS: Holding down the power for 10 seconds or more is pretty much the universal kill switch, from there should be able to bring up bootloader just fine.

Try booting in safe mode https://support.google.com/nexus/4/answer/2852139?hl=nl. 3rd party apps will not boot in that mode.

Not sure why you linked that or how it even pertained to me (especially since it's been long since resolved and was using as an example). Also those tips do nothing if you couldn't get past the boot splash animation to begin with.

How exactly do you get out of a boot-loop, when you can't even get into the rom to bring up the Power dialog in the first place like that instruction says? (The instructions you posted only works if you're already in the rom, holding down the ok button before it reboots, and I suspect all that's doing is clearing the Dalvik-cache which you can do from recovery anyways).
Also my problem wouldn't have anything to do with that, because if you flash a galaxy nexus recovery onto an N4, and reboot, it won't let you in because it'll ask for a password to decrypt storage, an the recovery will do the same thing, and my post which you quoted didn't have anything to do with a bootloop, just simply that you can get out of just bout any situations with a Nexus 4.

These are the most common bootloop solutions http://droidviews.com/2012/how-to-recover-when-your-android-device-is-caught-in-bootloop/.

Hi
I have twrp backup..
I wiped everything using twrp...
Then restore my backup..
in restoring option I had two bootloaders I removed first bootloader and used the second bootloader..
Also I removed data backup...
Then it start to load only bios screen

shouldn't have done that...think the bootloader you removed is the android one, while the other one might be the bios.
here is a link to some rom with flashfiles....i can't tell you how to flash because all the instructions are in chinese. there are different flashfiles, which peform different ways of flashing the system, eg. without deleting data, or without updating the bootloader.
maybe it's 'flash_factory_update_pos_bootloader' - my guess it only updates the bootloader partitions...if it works and you have a bootloader again you could probably load recovery again and restore your system / data.
(you might use 'flash factory 1st stage' and ' flash factory 2nd stage' as well (i think those flash the whole system again, but I'm not sure. it's just a guess.)
hope you will manage it
look at the flash_guide.docx, it's in chinese but with google translator you can get some information about it.
to use the flash tool i think you must boot into dnx fastboot mode...hold 'volume up' + 'volume down' + 'power' to get into dnx mode (yes, pressing vol up and vol down at the same time works!)

not at the moment...
can you once more explain in detail what you did and how you ended up having no bootloader anymore.
i'm still trying to figure out how you were left with no bootloader (can you post a picture of that ?bios?).
i just want to know whether this is somehow related to the ported twrp. from my knowledge there's no way to wipe the bootloader or whatever.
thx in advance

Hi
First thanks I used Platform Flash Tool Lite downloaded from intel website and flash the file it complete 75% but then faild. However it started on logo screen where I immediately but it in dxn mode and booted twrp and it worked. Still WIP. I will update you of the outcome.
As for how it happened... as I mentioned earlier I wiped everything using twrp and selected advice option where you select cache, system, internal memory, etc...
And restore twrp earlier backup but I modified the backup data stored in my pc it had bootloader and bootloader1.. then I removed first bootloader and renamed bootloader1 to bootloader. During twrp restoration process, twrp read my backup and shown me the folders that will be restored, there I noticed that I succeeded on having only one bootloader and also unchecked the data folder and restored it. Where it ended on attached screen...

if you can access twrp again, just restore your backup as it is...all partitions without changing anything.
good luck. hope it works.
now people know how to get to the bios/bootmanager (maybe it helps for dual boot)
do you know what options there were, something like boot from sdcard/otg (usb) etc...?

Hi
There where two options
Android IA
EFI Hard Disk
As for my issue I was able to boot twrp and restore my backup..
But it seems I played around bios screen which ended up not showing bootloader or recover option even bios....
It's feel like something running but not showing in the scteen. Is there any way to reset bios or a stock rom to restore the device like out-of-box status....

I found out that it was running through HDMI output in the initial boot and it will not show in the tablet screen..
I did it again with bootloader modification and got the BOIS mode and connecting my tablet to LED TV through HDMI output I managed to reset the bios and got it back to normal (know boot showing in my tablet screen...)
When i flash the file you share and used flash/blank setting it will reach 80 to 85% but fail in bootloader flashing. then i used DXN mode and fastboot flash twrp recovery it will bring the main service options where I did factory reset then it will start loading with little screen corruption. however it will load perfectly after couple of reboots but without the Halo Keyboard. i could not find out how to enable it...
Then i used my TWRP backup and restore it where everything working fine....
My request is it possible to modify the flash-able file you send to load a perfect stock rom. it will help many people as it will be easy to use with Intel android flash tool...???

Thanks mmusaad and danjac, glad that you unbricked it.
Can I ask how does one flash it with Platform Flash Tool Lite? I failed to infer the meaning of 'setup your board' from intel's description:
> You have already set up your board and connected the board to your host system. This includes assembling your board, installing the appropriate drivers, and flashing your firmware.
(I'm trying to run or install Linux on yogabook, which I feel may brick it a few times.)
Also, do you think one can enter the BIOS setting or boot device selection without bricking it first?
thanks

Hi sagi232123,
I will explain it to you in detail.
I taken a full backup using twrp.
Then I notice two bootloaders.
First named bootloader. "note: I don't remember the full file name."
Second named bootloader1.
I removed bootloader.
Renamed bootloader1 to bootloader using my PC.
Then restored using twrp again, I restored it fully.
Here I was shocked when it load the bios.
Do it and it should do the same.
