[Q] Why can't we dual boot the Vibrant? Example inside.. - Vibrant General

Rather than anyone come in and say it isn't possible if they don't understand the process, I'd like to hear the explanation from a dev or someone that has a solid understanding.
I know there are multiple devices that can Dual-Boot different roms/kernels, but all this time with my Vibrant I have never seen it brought up, or at least anything come of it.
I know many people would likely use it, to have a stable 2.2.1 rom with everything working as an alternate boot, but have an easily updated gingerbread boot that may have missing features like gps..
Even if you kept the main boot for rom testing, I haven't been able to find anything that shows we couldn't reformat the partitions and get this done.
Here is the one for the nook color, it has more partitions than ours does, but the scripts used are simple enough(and like I said, I can't find an explanation it wouldn't work for ours).
The only threads I found even reasonably recent are:
http://forum.xda-developers.com/showthread.php?t=1289618&highlight=dual+boot
http://forum.xda-developers.com/showthread.php?t=1152652&highlight=dual+boot
The second one someone mentioned that we couldn't split the rom partition, but my understanding is you repartition the main sd card into the additionally needed partitions..

The Nook color has a couple things going for it that our Vibrants do not.
The biggest is that it uses an open source bootloader, Das U-boot, whereas our Vibrants use closed source bootloaders from Samsung. Not having the source for the bootloaders makes it almost impossible to change to boot sequence.
The Nook Color using Das U-boot allows developers to do what they want.
One potential option for the Vibrant if a dev wanted to try it is to do the "unbrickable" mod to the phone which turns the phone into a KIT-S5PC110 development board allowing access to the phone before the bootloader kicks in, then write a Das u-boot bootloader for it (not using samsung boot loaders) where dual booting would be possible.
Beyond my paygrade

No open [source] bootloader=no deep changes.

Hmm, I kinda thought it might be bootloaders..
Okay, then I am wondering about options. I know the intl galaxy S 2 has an unlocked bootloader, but I haven't found anything about the t-mobile US variant.. That was the perk of the intl sgs2, but the bands would be for ATT..
I guess I have been waiting for the nexus prime(or whatever the name will be for tmobile version), but I wasn't sure.. since it is a google phone, will it have unlocked bootloaders?
I'm trying to do the research on what phone to get next, but so far none really stand out as a winner unless I was willing to switch carriers.. which I'm not.

It has nothing to do with unlocked bootloaders. The Vibrant has unlocked bootloaders. It has to do with closed source bootloaders.

[ATTN] - 3991 and 4349+ VIEWSONIC-RECALLED BOOTLOADER INFO here - UPD 5/8/11

Updated 05/08/11
ATTENTION - IF YOU ARE ON STOCK 4349+ or any MOD BASED OFF 4349+ USING THE NEW RECALLED BOOTLOADER! READ PLEASE!
Starting with the most recent but recalled update to Tap N Tap Viewsonic has introduced a new Bootloader being called the 1.2 bootloader. This bootloader is not compatible with mods or Roms based off of the Viewsonic Current Bootloader being called the 1.1 bootloader! This bootloader provides absolutely no known advantage other than being able to boot any new STOCK kernels. If you would like to use any of our stable ROM's (i.e. Vegan 5.1.1, Vegan GingerEdition and currently CM7) using Viewsonics currently supported and shipping bootloader (1.1) you must Downgrade your bootloader and TNT Version before you flash a new kernel or a new ROM.
Please download the following downgrade update.zip and place it on your sdcard renaming it to "update.zip".
http://www.gtabdevs.com/releases/4349_Downgrade.zip
Then power down your device. And power back up while holding the power button and vol + till your display says "recovery key detected" in the top left corner.
Using the volume keys to navigate up/down in the menu highlight "Apply Internal update.zip" if you copied the update.zip to the internal memory or "Apply External SDCard update.zip" if you happened to place it on an external SDCard and then inserted it before booting to recovery. Now select the menu choice using the menu key.
This process will take a few minutes. You will see a Box with an arrow and a progress bar while it applies the update.... when it is finished it will reboot to make the changes. Once the changes are complete your tablet will boot into Tap N Tap version 3588.
You are now free to follow all the tutorials about installing CWM and/or Kernels/Roms.
Thank you and good luck.
Be aware. I am not connected with Viewsonic in any way. I make no assertions as to the validity nor the safety of anything in this post. Do anything above at your risk.
That is a handy utility to have. Thanks!
How do we check if the bootloader is locked? I'm curious if the bootloader.bin in 3991 (which is based off the same branch) has this same issue.
Thanks!
Strange. One step forward and two steps back for Viewsonic. But, maybe, this means there is still some interest from Viewsonic for our tablet and chance for further development (maybe even Honeycomb).

If it too will not boot any other kernel besides a stock kernel built specifically for their new bootloader. That bootloader.bin also appears to be locked.

Does that mean it's locked, or does that mean that we just don't have the new source code to build custom kernels? I just want to distiguish because, if it's the latter, we can just ask them to release that like they did the 1.1-based source. EDIT: Already tweeted them. I see "1.1" in the source that's there, and we know that this is "1.2", so maybe there's new source code to be requested? Not sure.
I know that we can check for a locked bootloader with something like fastboot, but I don't think that works here. That's why I was asking.
Thanks again!

By all means ask for their new source... though I do not believe at this point they are required to give... maybe they are. So for the purposes of everyone else's understanding this is a LOCKED bootloader in the sense that we are LOCKED to their kernel...... nothing ever stays locked forever.... this is not however LOCKED in the terms that a select few who already know what's going on with this bootloader typically use the term LOCKED. Take it as you will.

To be honest they are probably tired of all the people calling viewsonic support with issues that are not on OFFICIAL viewsonic software... most companies try to do something to deter this activity in some regards.
Does nv flash still works to downgrade everything?

I understand this for "most companies" but Viewsonic is the company that openly linked on their product page that XDA is the place to be if you need support or any real use from your gtab.
We had to fight them to finally stop doing that. It doesn't really add up.
The only thing this does if it works is effectively pull the plug on the life support that was pumping any further life into the tablet.
We still have great "legacy" roms and infrastructure that make the tablet great. but moving forward all this does is concentrate our efforts towards them. releasing a workable open solution keeps us busy tinkering with it for months. Locking things down only sends us back to twitter and the like but now we have more members thanks to the new OD, TD, and amazon users.
I thought VS said they were going to work with the devs. Didnt they contact you guys? I thought they would of asked or told you guys what the best way for them to go would be. Did this never happen?

Yes, maybe. I had to NVflash mine because I accidentally flashed CWM over 4349 while i was playing in the 4349 recovery screen. The NVflash process worked, but for some reason my touch screen was borked (no touches were registered). Couldn't do anything. In the past a couple restarts with calibration.ini on the external SD would clear that for me, but didn't this time. I ended up doing NVflash with CWM as part9.img and then repartitioned with CMW and NVflashed again with stock recovery part9.img. Screen was still borked but cleared up with a couple restarts with calibration.ini on an external SD. So the answer is yes you can, but it may not be as smooth as you are used to. Of course it may work fine for you.

I've nvflashed back to 1105 at least a dozen times since last night (was doing upgrade / downgrade scenarios). So far, so good.
The bootloader is provided by viewsonic I think, it may be the key for some chipset feature, some other brand of tablet like the adam already has the same exact one
it's probably not locked but only doing something different like you said!
if I had to guess, they didn't lock it to be pricks...odds are it is locked to prevent people from flashing our current kernels to this to avoid messing things up...
so here's prolly how we'll be structuring our ROMs/Kernels now...1.1-based Froyo ROM; 1.2-based Froyo ROM; 1.1-based Froyo Kernel; 1.2-based Froyo Kernel and so on for GB if we're lucky HC in the future.
It's going to be a pain in the butt in the short-term, but long-term it'll only benefit current and future gTab owners as a whole if we stick to the 1.2 path alongside the vendor. This will keep confusion to a minimum, features to a maximum, and upgradability easy.
Thanks to all devs for their future support even through some of the PITA times
i have no options to choose between, aka no menu when i do all that, it just goes to a box picture and then reboots and loads normally.

There is no menu. It takes you back to 3588 and the ability to flash all current roms.
So this "rollback" is jsut a stock 3588 image, or is it something different?

[MOD][BOOTLOADERS] I9000 GB Bootloaders

I am not responsible for any damage to your phone, computer, home network, work network, social network, family pet, significant other, insignificant other, car, home, boat, or anything else in your life. By downloading and executing this software you release the creator from any and all liability, including civil, uncivil, and criminal.​
First, Thanks to:
Cezar This is another of my projects that wouldn't have been possible were it not for his help.
Watsa
If anyone feels I may have left them out, pm me.
Several people have asked "Where can I get the I9000 bootloaders?" I know there is a thread here that has them, but to get them you have to flash an entire ROM. I decided to extract just the bootloaders (boot.bin and Sbl.bin) and the param.lfs file from JVB factory firmware (downloaded from www.samfirmware.com) and package them in a Full Odin version (1.82) for those wanting them.
Flashing bootloaders is dangerous. They are one of the few things that has the possibility of hard bricking your phone. For that reason, here are some good things to do to prepare for flashing them.
Have a good, reliable data cable. Interruption of communication between your phone and pc will most likely cause a hard brick with bootloaders.
Use a usb port on the back of your computer (or #1 on a laptop). Communication, again.
Have a jig. Not much help if you hard brick, but if you soft brick its very nice to have.
I personally flash bootloaders from a good laptop with a fully charged battery. If there is a power outage, the battery in the laptop will have saved my phone.
When flashing bootloaders,or anything with Odin, don't touch your phone after you connect it in dl mode. Goes back to the communication issue.
After flashing new GB bootloaders, do not ever, ever, ever flash the old 3 button fix. If you do you will HardBrick your phone. If you flash any rom that contains a secondary bootloader (Sbl.bin) only, you will brick your phone
New button combo's
Vol down+power= Download mode
Vol up + power= Recovery mode
Powered off, vol down then insert usb= download mode
You will need 7zip to unpack files. Need 7zip? Get it >>HERE<<
If you need Drivers look >>HERE<<
If your computer's security software recognize's Odin as a threat, just create an exception for it.
I9000 GB Bootloaders
Installation:
*optional* Backup everything on your phone, just in case
*optional* Charge battery to at least 80%.
Download Bootloaders from above link
Extract files with 7zip
Open Odinv1.82 (Do not check/uncheck any of the boxes)
Click PDA tab (NOT bootloader tab)
Find the PDA.tar.md5 file included in the package, then click on it. Now click open
Put phone into download mode.
Connect your phone to your computer
Once you see a box turn yellow with a com port number, hit start. DO NOT touch your phone at this point.
Phone should reboot on its own to your home screen
IF your phone takes you to a screen with a Phone--!--Computer with a message about firmware installation failed and use recovery, DO NOT FREAK OUT. A lot of people have reported seeing this after flashing bootloaders. Simply disconnect your phone, close Odin. Reflash from previous directions. Odin should recognize your phone as beeing in Download mode, allowing you reflash.
Reserved, just in case.
Very nice thanks for this!
I just linked you in the OP of my ROM, will save people countless of questions about getting the i9000 Bootloaders.
Thanks!

Thank you, just what I was looking for
Great instructions and what to be careful of
It's worth noting that there's also a similar package for the Captivate-specific GB bootloaders, which carry a few advantages:
-They preserve the original button combinations.
-Phone+!+Computer is download mode, making it virtually impossible to soft-brick your phone, even if your three-button combos don't work and you don't have a JIG.
-They're specifically designed for the Captivate. As Cezar points out in his thread, it's unknown what, if any, difference this makes but it's not impossible that using incorrect bootloaders might impact stability or performance.

I am aware of that thread. If you had read it you would have noticed I posted 2 upload links for people in that thread, while answering a lot of questions.
It should also
Be pointed out that at least 2 rom developers recommend using I9000 bootloaders with their rom. There are also more than few questions about where to get these bootloaders in the q&a section.
It should also be noted that the 3rd post in this thread is a developer linking this thread to his OP.
Thanks everyone, 100 downloads in 4 days. So much more than I expected.
Also, If you have used this, how about a little feedback.
Doesn't this REALLY improve batterylife? I saw a thread in team-continumm about this
I'm on continuum6 with ATT bootloader does it safe to do this?
I'm not convinced that bootloaders improve battery life. Background data, screen brightness, auto sync, and a bunch of other things will, but loaders? I don't think so.
Yes, it is safe to use these with Continuum, or any other GB rom (except cm7 and miui).

I'm pretty sure the Phone-!-Computer is recognized as download mode on the I9000 bootloaders too.
What people think of stability based of which bootloaders you are using differs depending on who you ask and what ROM you're using. Some say using the I897 bootloaders would theoretically provide better stability because they were made for our phone while others say using the I9000 bootloaders with an I9000 based ROM would ideally provide better stability since the bootloaders were designed for the phone the ROM is based off of. Neither of these points have been proven and as far as I can see neither really impact stability with one noted exception and that brings me to my next point.
The I897 bootloaders are known to break the I9000 stock music player but some say this can be fixed by replacing it with the I897 stock music player. I however have not tested this since I don't really use the stock music player (no real reason as to why I don't I just don't).
So my opinion on this whole "Which bootloaders should I use?" issue is use the ones with the button combo you like most. I personally use the I897 bootloaders because I'm used to those button combos.
Also most devs generally recommend using the I9000 bootloaders because it's what they're using and it generally eliminates the bootloaders as being the cause of any issues you may have with their ROM.
It worked!
It worked great! Thanks.
Just out of curiosity, it booted into CWM after it installed lol...not a problem but kinda like a "wtf" moment. Still worked so its perfect thanks!

Getting BootManager!

Alright i have been keeping an eye out on a few things and came across BootManager which is a newer app that allows you to easily flash between several roms! Which of course is awesome if you want to try new ones out without reflashing as often. Unfortunately im am not quite as wise in the Android scene yet as i like, new to it with my Acer Iconia as i am, BUT i have been corresponding with the developers for BootManager and they have given me a link so we can submit the Acer Iconia to be added to the devices that can use Bootmanager!
I just don't know how to give them the variables they need!
Could someone that does know how to get the variables needed, (through adb shell or whatever) kindly submit it to them? Here is the link they gave me for submitting new devices, if you do do this, please post it here, so they don't get a bunch of repeat submissions on it, also, so i can keep an eye on the app and get it when they update it accordingly! Thanks very much!
Edit: I can't post links yet, cause i have not posted often enough. Please send me a message and i can give you the link that way! Or just close the space below and use it.
init2winitapps. com/submit_device.html
I'll do it in the morning.
Make damn sure they know they have to run "itsmagic" before/after ANY flash operation (I can never remember which, that's CWM's job!)
I did it too and i sent also a mail to the developers about itsmagic script!
good luck
If you read the information about this program.how it works and the phones that it supports will tell you it will most likely work on our device.THEY SAY WORKS ON PHONES ONLY.and only those WITHOUT LOCKED OR SECURE BOOTLOADERS
But you never know. They might put the efforts to write a new bootloader for this device.the program works by moving the bootloader.well no fifteenth then any other boot manager.
if im wrong and they make it works. I would buy it first.
Goddess erica.
This was posted a while ago and it doesn't appear that the a500 has been added to the supported device list. Has anyone been successful in getting this to work? I want to try it but I'm not sure what issues I might run into if it doesn't work. I need to make sure a Nandroid restore can fix whatever issues might be caused before to try it.
IF i remember right it says on there site this can ONLY WORK WITH UNLOCKED and not encrypted BOOT LOADER DEVICES. I TO Talked to the dev way way long ago..as for this to work they change the boot target in the boot loader to look at there software . then it will boot from there..
kinda like grub to a normal pc.. with the bios being the primary boot . If this makes any sense..
so i think it cant happen.. in the linux thread in our dev area .. someone in the first few pages it talkes about this very app and the flashing the bootloader out.. Dont think they ever figurerd a way around the security..
sorry simple answer is ABSOLUTELY NO WILL NOT WORK
THANKS ACER
I'm confused. My a500 doesn't have a locked boot loader. Thats the reason I got it. I have Thor's recovery loaded on it and I have been able to flash Roms without issue. To boot into recovery I just hold down the volume button and boot the device. I can load custom kernels or pretty much anything else I want. Am I misunderstanding what an unlocked bootloader is?
I had a Razr previously which had a locked bootloader and the only way to flash was to use a bootstrap because it had a locked bootloader. I had loads of problems with it which is why I swapped it out for the Galaxy Nexus when it came out. Both my a500 and Gnex are flashing like champs.
Where there later version of the a500 that had a locked boot loader? I don't think mine does.

Potential To Recover Note 4 Bootloader After Flashing Retail Firmware

***Updated: 04/09/2015
First, thank you BeansTown106 and ryanbg for previously sharing the information and technical expertise that has led to successful development of the "tool" that ultimately provides the means to recover a locked bootloader on the Note 4 Developer Device. Without your help and expertise this "tool" may never have been developed.
UDATE: 04/09/2015---There is now a step by step guide that will take you through a process that produces a flashable aboot recovery file for the Developer Edition bootloader if it becomes locked (by flashing retail firmware for instance). This backup MUST be done BEFORE your bootloader becomes corrupted and locked. It is strongly recommended that if you own a Developer Edition Note 4 that you take the time to make a backup of your aboot. This link will take you to a step by step process with links to the couple of files you will need.: http://forum.xda-developers.com/note-4-verizon/general/guide-vzw-note-4-backup-developer-t2962911. Thank you radionerd for the guide and again to BeansTown106 and ryanbg.
Most of us have heard or read about Developer Edition owners of the S4 or S5 that inadvertedly flashed a retail firmware or ROM that was not intended (safe) for the Developer Edition consequently turning their Developer Edition phone into a retail edition phone...locked bootloader. I want to emphasize that this method of recovering a Developer Edition bootloader has been tested and has recovered several Note 4 DE devices whose bootloaders were locked (purposely or inadvertently).
I always found it amazing that people flash ROMs for the wrong device. saw it a lot in Note 2 forums.
Can't believe people can be that careless...especially someone that goes so far as to buy a developer edition. Measure twice...cut once.

Yeah my Dev edition note 3 got ruined with running "nvbackup" so as a last resort i purposely flashed a retail rom hoping that would just make it work even though it would be locked...
This makes one start to wonder if we could then take a retail version and make it dev as well. If all the hardware is identical and the main difference is the unlocked bootloader..
Fastboot option is not available, but again, hardware being identical, this theoretically should be possible.

Well, that's kind of my whole point I was being a little sarcastic. With a locked bootloader, lets just say Read-Only, you cannot really overwrite something RO that has already been loaded per say... You would have to be able to fastboot, from my experience, in order to be able to do that. Now if they are signing it, if we could somehow impersonate the key and resign with a newer version number that might work, because they probably have allowances for signed updates.
To me, that might be the only way of resolving this whole locked bootloader issue in general. They obviously have the ability to update them, so we need to figure out how to sign it somehow and or understand their conditions. Meaning, what if they are already planning the next planned bootloader version coming within the existing one. So in this case, if it doesn't match what is expected on the check it will fail along with the fact the signature is not correct.

Ive tried to push a DE aboot to the retail Note 4. I can not get it to even write. Ive tried ODIN and ABD to push it. Any suggestions?

Have you tried it from the phone useing Terminal Emulator and the su command?
I could only copy aboot.bak via terminal emulator. I couldn't get through with CMD in windows 7. (I have only copied the file.)
It will not work... The tell tale sign is all of the capable devs of possibly accomplishing this moved on to Tmo or quit developing all together. Loosing Hashcode was a major blow to the dev community.

If anyone wants to send me an image of their aboot for research purposes, it'd make my day

I'm not certain that p6 is the aboot. I'm thinking it may be p7. I've asked for verification in the other thread.
is there an odin file for the developer edition device? if so will someone direct me there??

No there isn't. That is what we are all looking for. Samsung hasn't released one and I'm not sure how to make one from the retail version by replacing the aboot.

Well, we could do a dd if, blah blah blah and back up the partition once rooted, but this is not really what we want, because we want a factory clean, fresh partition. Not a modified boot, root, recovery etc... Can you guys connect to Kies on the developer addition and do a firmware upgrade and reinitialization option on the tools menu. Because this, would in fact, call out and download the whole image for the phone where you could snag it before it started trying to commit it to the phone. That is essentially what I did to get the factory image for the retail phone.

I've tried that. It says there is no image available for the phone. I've also gone to the Mosaic kiosks (Samsung inside Best Buy) and they use a different tool called Samsung Smart tool to reflash phones. They also do not have an image for the DE Note 4. I've also talked to Support and Advanced Tech at Samsung - both do not have the image. Finally I've talked to the Samsung repair depot and they also do not have the image. On a whim, I also got pretty high up in Verizon tech support asking them if they had an image. They do not support the DE device (as we know) and also didn't have an image.

Annoying Red Corruption warning screen!!

Hi everyone, new poster here but long time user!
I have recently rooted and installed twrp on my sprint lgv20. I also installed the stock international ROM to sim unlock for various uses. My only annoyance with the root is the red warning corruption screen, i was wondering if anyone had a work around or image to flash to get rid or hide the screen somehow with maybe an lg screen or anything.
Thank you for any suggestions,
Zach

Unfortunately there is no current fix for this. I am not sure what exactly is needed for this to be fixed, but I would assume that those people who are developing roms for the V20 have already exhausted what ever options there are.
Would be nice to have fixed, but since that screen is only during initial boot up I don't think anyone is terribly concerned with getting this corrected.
Hope this helps.
No fix
It is related to google
Not lg
I would imagine the reason for this is both for security and to let manufacturers know when a phone has been modified.
I don't believe there is a workaround for it either because it can't be done (doubtful as I am sure its software based) or people just don't care (honestly I am sure some developers were annoyed enough to look into it). I just don't think anyone has found a way around it.
This "feature" was introduced in marshmallow.
Edit: further research shows the Nexus 5x developers were able to work around it by replacing the image. So while it doesn't remove the function it hides it.

Please note this is a marshmallow phone not nougat so I am not sure the same concept would work on our phone.

That's what they did with the HTC one m7. Was to replace the image. It's just finding the way to do it. As Everytime the devs find a way around something. Then Google, the phone makers,or carriers patches it to make it harder next time. I understand why they make that tamper screen because to many people trying to root and bricks their phones lies about not tampering with their phones OS. They say don't know what happened I just turned it on and nothing. I am sure they will find a way to replace the image. It just takes time and it's low priority on the devs list of things to do.

It appears that the image is located within the bootloader. It would have to be extracted, changed, and put back in assuming there is not a signature check with it on boot up. From what I was reading it depends on which partition it is located in whether it can be done or not. If it is in aboot, Tilde has mentioned that we can't edit this partition. Unfortunately it doesn't sound like it's a simple case of replacing an image.

I can confirm it is located in aboot itself.
