[rom] basic stock rom

Here's a basic stock rom in case you need it sometime
the only modifications made are the su and flash_image binaries are included and ro.secure has been turned to 0 so you can adb remount.
How to flash download the rom from here
Place rom on sdcard
wipe data and all else
then flash rom
reboot and do what you need to do

Cool, you never know when you might need this.

Thank you! Appreciated.

How is this comparable to the rom listed here?
bit ly backslash fBEJnU
I want to have a known working recovery before I make any more changes to my phone. I am not exactly a newbie to this stuff (I have a Pandigital Novel that has been rooted and hacked into a nice tablet) but this is taking things to a whole new level for me and I need my phone. So I'm a bit nervous.
Of course I really wish I'd asked around some before I got to work on removing some of the stuff on it already (mostly known junkware from Virgin Mobile and stupid stuff like weblinks pretending to be native apps) after rooting it with superoneclick and installing root explorer. I need to know if your rom or the one I linked to will be able to allow me to roll back to a default installation that I can revert to if there are any issues down the road. Can you help me?
I apologize if this isn't the right place for this question. Thank you for the many mods I have seen you do already. I look forward to trying them once I have a fallback plan.

I'm not actually sure what your talking about but I've posted this on three different sites so far. I do that for the guys that don't go to other forums. There probably isn't any difference in the roms.

I'm not sure exactly how his is different since I didn't build it. I'm gonna guess and say his probably doesn't have the binaries in it, I'm not sure exactly how his is different since I didn't build it. I'm gonna guess and say that his doesn't have the binaries in it. I don't know. Honestly the only way to know for sure that it's stock rom is to get someone that hasn't rooted yet flash the recovery and get a backup of system.

My only excuse is that it was late when I found the thread and I wasn't reading clearly. Going by that statement his rom and your rom basically seem to be the same things.

Forgive my ignorance, but isn't rooting actually a requirement of obtaining the backup? Or did I misread the instructions somewhere? It'd be nice if someone at Virgin Mobile were to leak the complete rom somewhere so people had a fall back option besides trying to return the phone as bricked. (If that's even possible?)

Sounds like a good reason to pick a forum. Not sure if I'm a member of any places that do that since I run with adblock and noscript enabled most of the time.
Any chance you could link me to written instructions on how to flash the rom you have here? I know you have video tutorials but those are harder to follow for me because I am hard of hearing. Music I can do because it is "beautiful noise" and I can usually find some lyrics to get the words of. Your video HOWTOs are not good for me because I have to strain to hear what is being said.
Thanks again for your time and patience in replying to me.

Thanks. Dude above me, there is a rom flashing tutorial at prepaidandroids.net. We will help you out there. Its a site that specializes in on the Optimus v itself.
(Optimus V - Contracts Suck)

Thanks for posting this. It just came in handy when I was changing my virgin phone number. Part of the process is dialing ##841446# to bring up the activation menu, but the ## prefix on CM7 does not work, apparently only a stock ROM can do that.

Any way to put it on a phone friendly site? No matter what browser I use on my phone it will not download from google docs.

THANKS, this worked perfectly.
It's pretty much as described, a stock Opt V rom, with Super User already set up and installed.
Titanium worked on it no problem as well.

thanks a ton man! i needed to flash back to stock to get my 3G working again. if you flash a custom rom while youre between payments, you know, during down time, you may need to flash back to stock and run the activation app next time you put service on your phone.
worked like a charm. i thought my 3G was broken. im doing a happy dance now!

Anyway I can get a link to the stock rom with all the bloatware removed but not rooted?

Kernel Source

Hello,
Im not sure if anyone was aware, but the source code for the kernel is available from the Acer website. Im not sure if this would help with the dev of roms or cracking the bootloader. Thought I would throw it out there.
Its available on the Acer support page under the A100, and is around 100mb

Yeah, I saw that. Doesn't make a difference though, we need a unlocked bootloader before a custom kernel we can make with that is useful.

Back in my Xperia x10 days they were able to find a way to crash the stock kernel and were able to load custom kernels with a locked bootloader. Its probably not feasible considering it was a much older kernel version and from a different manufacturer...but one can only hope right? lol

Don't know if it helps, but the thunderbolt also came with a locked bootloader and devs figured out how to flash a custom kernel. The custom was also locked but supported what they needed it to. It was flashed with the same process as our flashing updates manually. Maybe some of the tbolt devs could help?
Sent from my A100 using Tapatalk

We could do a custom rom that through 2nd-init, but so far its been an uphill battle trying to figure it out. I'm not a kernel developer, but I've done some work modifying and working with cm7 kernels but nothing to this scale.
I do know that we wouldnt be able to change the kernel on this device or a modified recovery because there's some checking going on with the checksum of the disk images.

@crossix
Have you seen this thread in the Nook Tablet forums?
They found a way around the the bootloader problem.

I was thinking the above. Maybe we can make a work around through the kernal code. I havnt done programming on this low of a level but can scan through to see if and what checks there are and if there are any loopholes... I like to think they have a backdoor somewhere in there...

Excuse me, I was wrong. The tbolt with its locked bootloader was solved a little differently. I think what they did was flash an entirely different bootloader to it. One that was still encrypted but unlocked. Don't know if that's possible in this case but thought it was something to mention.
Sent from my LG-VM670 using Tapatalk

Maybe we should talk to nemith and fattire and they may have some suggestions. I am no where shilled at this level of development to talk intelligently to them. My development skills lie in the .Net field and at the application level. So I am not much help.

@painter... i have been looking through the nook forums that you referred to and i certyainly think that this is possible route to go with the a100. this is also way above my skillset, however i will be more than happy to do what i can if there are any developers interested. i have been doing alot of research into the locked bootloader and this is the most promising news that i have heard so far. I wish we could get more devs interested in this little tablet because it has great potential if we could get past the bootloader.

What Ill do later is download the code again, had before, but accidentally deleted it, and look through some of the more important code to see what can be found. Why would Acer put up the source code if there isnt a way to alter the kernel? Seems counter-intuitive to put it up without a purpose...

here is some info on 2nd init, if anyone smarter than me is interested in having a look.....good luck!..... http://cvpcs.org/blog/2011-06-14/2nd-init._what_it_is_and_how_it_works

Because they have to, its required by gpl to make the source public. Just because they make it public, doesnt mean that it'll compile properly though. But, in this case it does compile cleanly and with it we could probably take bits and pieces of cwm for the a500 and get it to work (their gpl version not thor's recovery). How to do that tough with our current encrypted recovery I dunno.
I looked at the thread and it definitely looks like something doable but what offset would we use and how would we tell the boot partition to go look for a custom recovery when we cant even open it to alter its contents since it and the recovery partitions are both encrypted.
If you make a image of either partition using dd and try to mount it and read its contents you see gibberish rather then editable files in the images. might be able to poke at it with a hex editor, but that's beyond my skill level.
Sent from my MB860 using XDA App

Im still in the extraction process, and it is a rather large image. Its around 500mb compressed. I can take a look into it, but cant make any promises that Ill find anything at all. I understand the gpl and whatnot, and the partitions being encrypted, and am just hoping that somewhere in the kernel is a clue as to what is being done that can help us along the way to cracking this thing.
I didnt think of this until now, but is the newer A500 encrypted? If s, maybe we can find the difference between the older and the newer version somehow and see what they are using. Just a thought, could be completely wrong.

from what I understood (I could be completely wrong though) one of the newest updates that brought the a500 up to 3.2.1 changed their encryption method so itsmagic (their security hole) no longer worked. The work around for that was to downgrade to 3.2 and install cwm / itsmagic and them flash a recovery 3.2.1 image.
Sent from my MB860 using XDA App

Hmm, Not sure. Ill look around. Im still trying to root my tab, have been unsuccessful thus far, and about 3 hours into trying..

is there any benefit in opening the device and sniffing around? I know the bootloader's encrypted but some of it might not be? That's how GeoHot found the first iPhone unlock exploit; by shorting two pins or something?
I also know it's possible to read NAND chips with an Arduino to some extent. I dunno, just talking out loud...

Never thought of finding a way through the hardware itself. I have never opened my Acer, probably wont. I have a Chromebook and they only way to install another OS on it was to flip a switch and pop the cover off, since it has a button thats enabled with the case on that prevents writing to specific portions and whatnot... Good thought. Maybe someone will look into this further.

I think its very nifty that it has an expansion slot for a cellular chip. All the specs I can find on the 3g a101 show it as having half the RAM. Wonder what it would take to pop a 3g chip in there and get it working. :-\ You would probably have to flash the firmware from the 101 to get it to see the chip...

[XYBOARD][RECOVERY] Funding for Dev to create Recovery/Rom

I would like to know how many forum members would be willing to donate funds to any developer willing to seriously work at creating a recovery program and maybe one rom for the Xyboard 10.1 4G/LTE device.
I realize the bootloader is still locked, but devs have managed to bypass the bootloader on other devices using some very creative thinking. The bootloader on my Droid Razr is still locked, but we have Safestrap, CWM
There is also a member i saw that would be willing to donate a xyboard for testing.
I would be willing to donate $100 towards this project.
We need to show the manufacturers that our platform is truely OPEN SOURCE?

so, here we meet again, chumboy
well i'm in, offering 50$ for unlock/bypass

welcome! hey again.
fair amount of views, not many investors.
surprised, it's verizon's main tablet that has 4g (besides the galaxy tab 10.1 which i heard is discontinued).

I would get in on this. I have actually been trying to figure out Hash's safestrap to see how it is replicated for different devices.
Sent from my Droid3 using xda app-developers app

I know it can be done...it's just a matter of interest. Is some dev interested in spending time to figure it out.
we have recovery for many, many devices whose bootloaders are locked.
SafeStrap would be great....or TWRP.
So far, we have $150 available for anyone who creates a recovery. Come 'n git it, devs!

why not create a simmilar thread at xoomforums.com... guess the most of interested useres aren't reading much @ XDA since atm there is no development going on for this device.
if you do so, just be sure to link to each other thread, list the users & amount and sync those two threads in their first post like:
"chumboy (xda/xoomforums) - 100$
nchantmnt (xda/xoomforums ) - 50

maybe u know of some other forums as well

25 from me if the recovery will working for international xoom2 too.

Hello guys,
i want to help you to get a custom recovery for your XOOM2,
because i´ve long waited for a cwm that could be used on my phone - Motoluxe XT615.
And i got sick of all those devs out there who don´t want to help us to make it even easier.
So my mates and me tired a lot together. Finally a chinese developer team got it.
So i hope i can charge my knowledge with you.
My first few questions are:
- Any tries of implementing 2nd init?
- Which type of internal storage (MTD, EMMC)?
- Locked bootloader (realy think so )?
- Can you upload the init.* script in the root of your phone?
I hope you have rootaccess

for 2nd init i really lack the knowledge of how to do this, but atm trying to get to know more about it. is this even working on ics?
internal storage should be mtd if i'm not totally wrong...
the bootloader is locked, we are sure about that and about the init... will upload it for you later... first got to recharge^^
what kind of approach is it that you have in mind? i may lack the knowledge about bootstrapping etc, but i'm eger to learn

The 2nd init should not be a problem. Internal storage is /mnt/sdcard/ external drive can be loaded on /mnt/usbdisk_1.0/
The bootloader is locked, Motorola has not released this yet. However, I did decode a file that had the agreement for unlocking the bootloader so this leads me to believe it will happen in the future.
My knowledge of bootstrapping is limited as well but I do know that if Motorola's system catches anything of another system trying to run, it will reject it and either bootloop or reboot. The secret is in the boot stage not interacting with factory boot at all.

wow...you guys are talking way over my head. i understand somewhat, but at this time, i can't contribute anything but funding.
and emotional support !!!
let me know what a non-coder like myself can do to help you.
so far, we have $175 available to dev who creates recovery.

Devs,
Just want to make sure you dev's are working on the Xyboard 10.1" with LTE connectivity and not just the wifi only device.
It's the Xyboard MZ617 7444.

Realy guys i don´t want your money
On my phone we got a CWM recovery via hijacking battery_charger.
That means when your phone is of and connect it to any kind of power supply it normaly starts this huge battery loading animation.
We simlinked this battery_charger script to a folder that excutes the CWM.
So everytime i shutdown the phone and connect it to powersupply i´ll enter CWM.
I´m quite sure this will work on your tablet, too.
I just can help you with this kind. When your aim is to get a real 2nd Init i can´t help you,
because there my knowledge ends too.
But for beginning i think it would be nice to have any kind of custom recovery, or?
To beginn i realy need the init scripts guys. Open your filebrowser and go to internal storage root, there they should be.

Sorry was abroad for some days
Yes, any kind of custom recovery would be nice. Here you go with the init.
Any information on how you are going to do this would be nice so we can alter this to our needs (thinking about some bootloader to choose weather to load cwm or automatic just charge after some seconds would be nice)
What are the limits of this way? Guess we will not be able to flash kernels, right?

First off, sorry for double-posting
having read myself enough into 2nd init i guess there will be no way to get this running on our xoom2/xyboard models, as the devices need to be running some froyo-kernel to get this working. Maybe even a tweaked gingerbread-kernel can be used for 2nd init, but it should not be possible with honeycomb or even ics. So i guess our best bet is to concentrate on the option luxxx123 is going to give us.

Wow...interest seems to be picking up! That's great.
the Xyboard is really a pretty good tablet.
What you guys are discussing is slightly over my head so i'll just lurk and help when i can.

The kernel version is 3.0.8 Does froyo go into the 3's? I thought it stopped at 2.6.
Sent from my Droid3 using xda app-developers app

Youre right... Froyo stopped at 2.6 but if i recall it correctly the hijack of 2nd init doesnt work with newer kernel versions. But i would be glad if i was wrong here
Gesendet von meinem XOOM 2 mit Tapatalk 2

I tried pulling the 2nd init and hijack from my Droid 3 which has Hash's Safestrap. I customized a few things for my Xyboard and put the files in place but it put it into a bootloop. You just may be right.
Sent from my Droid3 using xda app-developers app

I'll save you guy some trouble, boostrap and safestrap won't work, bootstrap hijack method will not work, bootstrap is open source and you can find all the stuff on github by koush, safe strap by hashofcode will not work, it utilizes the same hijack binaries of bootstrap, this is also open source on his github,
Both can be built from the source, with the recovery files build from cm9 or cm7 .
I have built the recovery and the bootstrap they simply do not work.
That said i have gotten rid of my two (I even at one point offered to send one of mine to a known developer, not one took me up on the offer that's why I learned how to do it myself.
Now someone here brought up a way that peaked my interest, syslinking the charge while battery off script to a custom script to boot into a custom recovery' (cwm or twrp) this seems like the most likely at this could be done.
Someone with some time could find the script in question and post it I'm sure myself or someone else could get something going.

Developers

Is there anyone developing for the Kindle Fire 2?
As far as I can see, the answer is no but I'm not sure if you're all just been busy and work and don't have much to post yet.
If there is no dev team(s), or devs at all working towards getting this thing with a working Recovery and ROM, I will most likely put together a team this weekend.
Also, assuming there are devs, may you share any findings you have? Why or why not the recovery is being a difficult process and whatnot.
I will probably put together a team just in case, I just can't make promises until I meet this weekend and see if they want to work on this.
If/when i get a team I will make a thread for it and post any news updates as they happen. I really hope we can all get this thing cracked open soon!
Thank you in advance!
UPDATE!:
I hit reply instead of save, so I lost my post sadly, so bullet points!
-I could not contact the main dev.
-I do not plan on making a full dev team anytime soon.
-Powerpoint45 and Hashcode are making progress, moreso Powerpoint, although eventually it seems Hashcode plans to have a workaround, just no ETA or promises from him, but there is more hope than before!
-I will still help and try and offer advice to any newer people, I am not a dev, but I have a decent amount of experience that would be enough to help new people.
Good luck to all!

I too would like to know this. I don't have much but I would donate what I can to the first dev or team to get us past this locked bootloader.

Thanks I'll let you all know what gets decided this weekend. One coder agreed so far but their experience with Android is limited. The main person I have yet to talk to but he is the one that constantly messes with his android devices since android first came out. The issue is that he does not have a kindle fire, so I may have to buy them ones or lend mine to them to get the coding started.

I have been flashing ROMs and whatnot for a couple years, done my vibrant, galaxy s2, and a few others, but have no coding or developing skills whatsoever. I imagine everyone starts somewhere but I don't have the slightest idea where to begin. I would love to learn though. A locked bootloader seems like a steep challenge compared to obtaining root or developing a ROM. I might be wrong in that regard too.
Sent from my SAMSUNG-SGH-T989 using xda app-developers app

Depends on how the bootloader is signed. The Motorola Droid and Droid X were relatively easy to crack but other devices may never be cracked without help from the manufacturer.

Since this device already has Root, I don't know that the bootloader will be an issue. The Gen 1 Kindle Fire has JellyBean running on it already so it may be a (somewhat) simple task to port that to the Gen 2. I'll have to pull it and see what may be device specific to get things running on the Gen 2, but it can be done. We'll need to first get a custom recovery going to allow the ROM to install.
This looks promising from the Gen 1 forum. Perhaps someone can reach out to the dev and see 1) if he's ok with us using it and 2) if he can help get it going on the Gen 2.

A locked bootloader generally means no custom kernels. Kexec is the only workaround (that I know of) other than unlocking, to start a new kernel . Root simply gives su access, it can't, in and of itself provide kernel customization.

Didn't the recovery for the KFHD's get put on hold? The stock recoveries won't usually let you flash anything that's not signed.
I'm not a dev but it seems like porting the KF1 ROM over to the KF2 should be pretty easy. Other than the bootloader, the hardware changes were minor, just bumping the CPU/GPU up one model and doubling the RAM. Again, it all hinges on unlocking the bootloader or reverse engineering the key it's signed with. Anybody have access to Amazon's EC2 system?

This is true, however the question was around custom ROMS, not kernels. You do not need a custom kernel to run a custom ROM, it's just nice to have the flexability.

I believe there is one guide for the basic rooting, and another for the steps on using root to make your Kindle do some decent stuff (new launchers, lockscreens, marketplace, all the good stuff!)
However, the issue with the KF2 is not really getting ROMs on, it's the step before it which is getting a working recovery so we can safely flash ROMs onto the device. Once that's done it shouldn't be hard to get a ROM, and it may be even possible to just use a KFHD ROM without any issues, BUT we need the recovery on here first, and getting around the locked bootloader.
To my all caps warning, just check the Q & A forums to see all the people who tried the recovery, rom, and rooting methods for their KF2. Most end up bricked.
If you are experienced in the sort of thing, go ahead and try at your own risk, just be careful. As you may notice, yes, most if not all (can't remember off the top of my head) of the methods we use to root ARE from the KFHD, so yes, some things do work, but way too many times I read about people that tried to put software that wasn't for the KF2 on it and it ends up bricked. Thankfully people seem to be fixing the bricked Kindles, but it's a very unfortunate experience people shouldn't have to go through.

Forgot to multi quote :\
This would be great I think! We have the tools so far, it's just that none have been made specifically for the KF2.
Good luck on the app as I'm sure many new KF2 users will appreciate it!

I burnt out my usb port trying to make a fastboot cable. I tied the wrong pin in... I'm waiting on my replacement. I'm going to try to use the revrom to get the cwm on my kf2 if that works, I'm sure we could get someone to make a touch cwm or twrp for the kfhd. If the kfhd cwm works, we could use the touch cwm/twrp. Perhaps it will need to be modified... perhaps not. I suspect that the cwm won't work perfectly and we need to modify it to use the correct partition table.
I should mention that using my current factory cable, I can get to fastboot. I just burnt out the data pin. I tried to use dd to flash the revboot stuff, but I forgot to do the part where you get past the locked bootloader... instabrick

I was trying to make a fb cable earlier today but the connectors were too hard to solder so I need a new cable to work with. I had same idea as u. Trying to boot into a recovery like cwm

[Q] Getting Root with Redirect to an Old Firmware?

Hey.
Did anybody know or can explain why it should not be possible to redirect the update process of an AFTV to local older Fimrware to make downgrade?
I thinking about this idea some days and found now this topic here, while I was searching for a solution of my update block problem.
Perhaps we could test it with bind9 on windows first and later we can port it just to an device like the Rpi.
Greetings by I_did_it_just_tmrrow
EDIT:
I think I can guess what is the problem.
The 51.1.3.0_user_513011520 brings the new recovery, wich blocks downgrades.
But is there now way to refer to "signed" rom wich the old recovery?

This has been brought up and explained countless times. The update.zip as a whole is signed and cannot be modified. The very first line in the script checks the timestamp of recovery vs the timestamp of the update. If the update is old, it will fail.
In addition to there be no way to get an old update.zip to be downloaded by the software in the first place.

That's not entirely true. You just need to wait for the Fire TV to find an official update and then run your own DNS server to redirect the download to a file you host yourself.
I've successfully done it (could have swore I told you about it), but regardless, it doesn't matter because like you said, there are checks in place that keep the Fire TV from installing an old update.

If you remember the last time someone tried that, the Fire TV rejected it because the manifest version didn't match what it was expecting.

Ah ok, I must have missed or forgot that discussion.

I'm a couple of years behind. Last working with roms on ICS, but I remember being able to alter update.zip files without loosing signature by opening it in winrar and making the changes. Memory is fuzzy, but I know it worked for me when developing a rom for the Toshiba Thrive. Could this not still work. For example, pull the official source code, open and add SU with permissions, then save. Then intercept the update as stated before. I know, not as simple as that, but it seems plausible from my experience with altering signed files.

You would have to bring some links with direct info how it is done to show the guys what it might take. And how feasible it is on the FireTV. If you find some link. please post them.

md5sum or other checksum will fail
