Password protect recovery? - Sprint Samsung Galaxy S III

I have Cerberus but it seems like all a thief would have to do is flash a rom to bypass it. Is there anyway to password protect recovery? Seems like a good idea.

That is very true. I would suggest emailing the TWRP and CWM devs to look into it.

That's true. There's quite a bit of discussion going on about this in various threads and other sites. Another thing to consider is that thieves are usually not smart and need to know about recovery and flashing ROMs first. Unless it's a tech savvy thief, the max they're going to do is factory reset because that sounds the most obvious. Cerberus will survive a factory reset if you've installed it to the /system partition.

Cwm vs twrp?

Specifically for our device, which is better and why? I've searched the entire forum for any relatively unbiased comparison with no luck.
Why is one better than the other, excluding personal preference?

cwm is more reliable. almost bricked my phone with twrp I don't trust it as much.
Sorry to say but this is a topic that has been discussed to death. A simple search would get an overwhelming list of results, just sayin..

Cwm for me
TWRP all the way!:good:
I like TWRP because I have a touch screen, I want to use it. The buttons on TWRP are nice and big. CWM touch is too easy to push the wrong thing. And queuing up multiple zips too flash saves me a little time during my almost daily flashing

Twrp appears to be faster at backing up and restoring. Just faster overall. However it looks like it destroyed my sd card.maybe it was just its time...

TWRP for now...
Had CWM for my old optimus one and install it on my S2X first when i bought it... but recently change to TWRP and it's big improvement for the GUI... No more need to flash Darkside Wipe Cache and Darkside Full WIpe... For now it's working fine, but some people says they almost brick their phone with TWRP...don't know why... i'm still little nervous with it...
In my opinion twrp is the best. The openscript support, and also the flashing of multiple zips is great.
TWRP because it is easier to use, and you can flash multiple zips.
Cwm i gotta go the safe route cause im a noob.

Forcefully inducing a soft brick/boot loop? Possible?

Is it possible to force a soft brick/boot loop that cannot be fixed by factory resetting? ie the only way to fix would be to flash a different rom using recovery or Odin.
Yes it can be done easily

How do I do it? If it's not too much to ask please.
Delete some system files.
Sent from my SGH-I747 using xda premium
Sounds like you're trying to force someone's device into an unusable state in order to make them flash a ROM dude. Not cool if that's the case. You should let people do what they want with there devices. #creepymeterishigh
No no. This is purely for personal use. I do not attend to do it to anyone else's phone. Wouldn't deleting system files be solved by simply factory resetting?
Or this is his way of getting a new phone through warantee lol

haha no, it's for experimental fun. Wouldn't rooting your phone already void the warranty anyways? I'm just trying to learn more about androids since I'm fairly new at all this. I'm thinking learning how to boot loop will help my understanding at how it happens and know how to deal with it/avoid it in the future

start flashing thru odin, pull cable out half way.
Would that only cause a soft brick? I do not want to cause a hard brick where I can't even access recovery /download mode
Just go in recovery, mount, format system, have fun with your soft brick
Sent from my SGH-I747 using xda app-developers app
on your side note. A factory reset will not fix deleted system file. They are the files it refers to during a reset.
And there are many ways of causing a soft brick. MANY. What will you hope to learn by deleting files so your system won't start? I personally don't believe you. But i also personally don't care..

Personally when I was with sprint I did it to my gs2. If that's whhay you're trying to do then do it. He's a adult no sense coming on here lying.
I did my soft brick going into Odin and flashing a radio on the PDA slot......BOOTLOOP

Data recovery possible

Hey guys. I am not very optimistic but I thought I would ask. My mom asked new to root her phone and put on cyan 10 for her. During this process I had some issues and wound up rendering to stock with Odin and then tied and flash successfully. I didn't realize though that Odin would completely wipe the internal and she neglected to tell me she had pictures on there she wanted. Any possible way to recover data after a flash through Odin?

Worth A try
I've flashed through Odin numerous times and have never had any personal data deleted. Maybe you did something wrong? As for file recovery, use a data recovery software and see if you can retrieve files from it. I know it works on USB flash drives and RAM drives, it should, in theory, work for phones and devices as well. I use 'Recuva', I haven't tried it on my phone yet but I've recovered from USB drives and old hard drives and works like a charm.
If you do use this method, it's best to recover files to a USB drive or anything external, for safety and reliability reasons.
I haven't ever had that issue either. It's partly why I didn't bother backing up those files in the first place. I'm going to go pay her a visit again today and brave the scolding to give this a try. I'll post back my results. : fingers crossed :

There's also an android app called Disk Digger that might be worth a try. I've never used it myself though.

Well happy to report all went well. It of her 970 photos, around 2 were corrupt (artifacts in the picture etc). Of the 67 videos 8 were corrupt. All in all a 99% success rate on each. I also setup dropbox on her phone for good measure. Thanks for the assist guys. You saved my ears.

[Q] Password protect both Download mode and Recovery????

Hey guys..
Straight forward question..
Is it possible to password protect our Download and Recovery modes?
And i mean when you press and hold vol dwn+home+power method. Not through the android software reboot menu.
I want/like this idea because if someone were to steal my phone. They would NEVER be able to flash a custom ROM or even flash a stock ROM img. They would be completely locked out making the device useless to them.
The only way i think they could get past it is by using JTAG to overwrite the download partition with a stock one. But hardly anyone has a JTAG device.
Well this would be awesome. lol
Have at it
Im guessing it would require a modified bootloader. Not really sure though. Ive wondered about this myself. Never seen it done though.

I think it would be the ultimate level of security. And i agree a modified bootloader would be necessary. How one would go abouts creating one i am clueless.

As am I lol! This ones a bit above my skill level!
Problem is, itd have to be redone for each model. Unless there was a way to have sonething that could sit on top of or intercept power on and run before the bootloader....I really have no idea though, just tossing ideas!

that is a great idea indeed.:good:
Very interesting topic, but I think it is impossible to do (Recovery & download) are design to prevent forgotten password issues.
What a pity
Guys i thnk if it can be done
It will be easy to install it on our devices if rooted (stock android)
As companies like sammy ,htc have diff kernals
I thnk we can successfully do this fr nexus ,micromax ,karbonn etc.....
Lets have a try
Ny one tried this before
If so plz gimme a guide of it so that it will b easy fr me
Lemmi try my best fr us to have ultimate theft protection on our android devices
I hope if it wrks google may add it on its future devices
The "ultimative" protection would be:
When a phone is stolen, you can remotely trigger "the suicide button" xD
When it is triggered and the phone receives the command (Even if the phone is running other ROM) it reboots the phone and erases the Bootloader and some other things that are important for the phone to work.
Best. Protection. Ever.
Second thing I could imagine is that phone companies could protect the download mode with a password (12 digits or so).
That password will come printed on one of the manuals when you buy the phone.
If you attempt to flash an image in download mode, you will be prompted for the password.
And, optionally, if you put the password 10 times wrong, it will erase bootloader and etc.
Third idea: The download mode only will prompt for a password (printed on the manual), if you atempt to flash another ROM on it... Because this will change the confidential signature that the old ROM has passed to the download mode.
(I am not sure if this could be done. I'm just saying ideas...)

Rooting really worth it??

OK so I rooted all my previous phones with no issues, just wondering running stock this phone is pretty fast don't know how much "faster" it can get. I know all the features rooting can bring like removing annoying bloatware, carrier iq, build props etcc. What else could you do with these roms? With stock I already could do a lot of the stuff I couldn't do with previous phones running stock. I know overclocking, undervolting anything else I missed that these roms provide apart from asthetic looks?
I guess I just wanted the opinion from people rooted to see if you get that "night & day" difference effect that you get when you root
Sent from my SGH-T999 using xda app-developers app
If it wasn't for removing bloat and carrierIQ i would be satisfied with stock. BUT AOSP/AOKP is my main reason and 4.2. The TouchJizz ROMs aren't my thing overall. But i think stock out of the box is great, i have plenty of friends with the S3 that wont let me tough their phone cause they are so happy with it stock.
Sent from my SGH-T999 using xda premium
There are way too many junkwares phone provider put on the stock TW. Even pure TW contains Samsung's junkwares. Rooting will allow you to remove or freeze those junkwares which makes the phone performs even better with better batt life. You can also install a firewall such as DroidWall to block internet access from apps. Block ads with AdAway. Block apps from autorun themselves when certain event occurs such as power is plugged in. There are endless helpful things you can do with a rooted phone.
I'd suggest reading more about rooting, flashing, custom recovery and see what you're missing without root.

Yes rooting is really worth it.
People that I work with have note 2 and s3 and my s3 is much faster and snappier then all of theirs.

Yeah this is one of the few phones that don't come messed up from the box, I would say battery life could definitely improve on jb so I know rooting will help that a bit. Thanks for input

Yeah all those things you stated I already knew, I like the adaway stuff several other apps that can do that too. Also voodoo sound is nice. Voltage control all that.. I'm pretty careful and all but I guess I just don't want to deal with all the hassle. Backing up nv, roms, apps whole nine yards.
Sent from my SGH-T999 using xda app-developers app
My question is i read around forums people stating that triangle away can't take away the tripping counter when you flash a s3 that came with JB already installed out the box any truth?
Just would like to know since I have a long warranty on it just in case.
Also backing up your emei would insure you will get it back if something goes wrong? Because I saw in that forum it was a mixed bag some people could get it others couldn't and had their 4G missing too
Sent from my SGH-T999 using xda app-developers app
Yes............
Rooting IS worth it, next QUESTION!
Lol
And they have a thread on how to not trip the counter.
And as far as stock jb tripping the counter... haven't heard that but I honestly dont think it will unless you flash a new rom
Sent from my SGH-T999 using xda premium
Counter thing is dumb in my opinion. I'm sure there is a work around, Odin back to ICS and then Odin JB then go from there maybe, idk.
Yes, banking up your imei is a full proof plan and use twrp instead of cwm!

Oh okay one more thing backing up. Where you guys backup your roms internal or sd card Which one is more ideal? Just wondering since I never had phone with this much storage. I assume in touch recovery it let's you decide when you're backing up right?
Sent from my SGH-T999 using xda app-developers app
Ideal should be in sd card.
NOTE* always make a backup before you flash anything, I cant stress that enough because it will save your life*
Also do not mess with it while its in your card because it will not boot up. My suggestion is leave it as is
To be honest though either or, it would not be a problem... me, I have it in my ad card

Rooting is definitely worth it. Probably the best things you can do with it is remove bloatware, install an Ad-Blocker, and control the CPU to increase battery life or performance. With the Triangle Away app, you can easily reset the Custom Binary counter for warranty exchanges as I have done a few times.

The is an app called triangle away that resets the counter. If you don't know, don't offer useless advice.
Backing up your NV data is a "fool" not "full" proof plan indeed tho.

When in recovery you can choose where to back up to. I would personally read thru the stickied threads and get some information that has been deemed infallible by the higher ups. Asking basic stuff on a thread sometimes leads idiots to respond like they know something. The info on the stickies is concrete and not opinion based or anything.
