Hard-Reset-Proof writable memory? - General Questions and Answers

Quick question for all the Dev's out there. Is there anywhere/any way to write (a tiny amount of) data that would survive a hard-reset?
Cheers

I think it is possible include this data when cook the rom an flashes this rom to your device. CMIIW

Thanks, but what the OP is after is a way to write the data after flashing the ROM.

Sometimes you can write to extendend rom, but i guesss it might be device-dependent. I'm sure it worked on Wizard and toshiba G900. And i don't think that extrom is wiped during a HR. I never tested it, but that might be something worth trying. I just don't remember how to make the extrom writable on HTC's - it's writable in the g900 by default and you can access it by typing \extpart in total commander's address bar. But i think it was a bit different on HTC's.

Most newer devices don't have Extended Rom though. My Kaiser & Raphael don't.

Oh, ok. That's why i said it might be device-dependent

We're looking at ways of making "WIMP" type app that cannot be removed, or have it's settings wiped. I don't think it is possible, but we are hoping.
Getting the App Cooked in is easy, stopping the settings getting wiped after "Clear Storage" is another thing. Is there a way to mark a File as in "In ROM"? Or maybe write some data to an area that isn't wiped?

Ok, no extended ROM, not like it's wide public knowledge. But how in the hell do we delete unwanted crap? I'd rather not have to do the anti-bloatware reset, I'd like to be able to have full frigin control over my PDA! Anyone?

For "full frigin control", you'll have to learn how to cook your own ROM. Or, you may find that someone will post one here that suits your needs, in time. Other than that, you're stuck resetting during the "customization" process.
Is the statement that there is no Extended ROM on the Kaiser relevant for the Tilt as well or is this related to only the Tytn II HTC ROM? Specifically, during the carrier customization process on the AT&T Tilt, if there is no Extended ROM, where are the customization CABS being called from and how can they be extracted as others have done?

Do a search in \Windows\ for *.cab files and you'll find your answer.
(Total Commander is a great tool for searching your device, among other things)
Thanks for the info.

You can delete them without a problem. They've already been used/installed, so they're just taking up space now.
Hope that helps.
I tried deleting some cab files from my windows directory, but it says unable to delete because they are part of the rom. I'm using at&t rom.

If you hard-reset, everything will be back as usual. I noticed Kyphur's post above mine eluding to not being able to delete the files because a poster's question above him. I was under the impression that changing the attributes of the files and then deleting them would work. But hey, I could very well be wrong.
I, unfortunately, don't have a Kaiser anymore (horrible story, I'll try not to cry thinking about it), so I can't test it out right now. But try using Total Commander or something to change those attributes and delete them. As I said though, once you hard-reset, they WILL be back. Post back if that works.

Sorry for my English and i wish you a lot of fun with the rom
* Dont Flash this Rom... To many Bugs. sorry guys *
Congratulations on your first ROM!!!!!!
Have you included any of the fixes for the bugs that have been found in Gnatgosplat's ROM? I would like to try yours but would prefer to install a "fixed" version.
Thanks for having my name mentioned here. It wasnt anything much that I do. Thank you BlackDragon.
This isnt my first time flashing ROM but this time around I am faced with TeraTerm issue. I get the response "Cannot Connect" when setting up the TeraTerm connection. I Hard reset my device, Clean Storage and yet I still get the same response. Any help will be much appreciated.
Thanks

Ensure your Tornado is in 3-colour mode
And i wonder whether you can find the "usb" in the "Serial" option.
If not, you can choose any such as "com1", and click ok: donot close TeraTerm.exe.
Open another TeraTerm.exe, and then you can see the "usb" in "Serial" option, choose "usb": before clicking "OK", close the first TeraTerm.exe application.
In this way, i think your problem can be handled.

Everytime I wanted to flash I followed KarHoe's guide to the book just to ensure I dont miss anything out; dont want to brick my precious Tornado though. Yes the device is in 3-color mode. And there is "usb" in the "serial" option of TeraTerm.
I tried your suggestion but Unfortunately i still "cannot open"...
Thanks for the help anyway.

I take it Tera Term is just not able to find the phone. Try unuinstalling active sync and reinstalling active sync. I think it has some thing to do with your PC not reading your phone. If you can get it into bootloader, you should be able to flash something on it.
Don't forget to unselect "Allow USB Connections" in ActiveSync before you use TeraTerm!!
THANKS to all you guys...
My heart-felt thanks to all you fantastic guys. Firstly to Blackdragon_860 who worked tirelessly through the day and night to release this fantastic ROM. (I know, as I do, we, ROM junkies were eagerly waiting for a refreshed ROM to be flashed). Secondly to all you guys out there who provided suggestions on how to solved my TeraTerm issue. Also to those who symphatised with me. THANKS! You guys are
I somehow managed to get TeraTerm to connect I did two things. First in Settings>Connections>USB to PC>set to off. I also switched the usb port. So I cant exactly determine which of these two solved my problem.
and here are some stats and pics.
Available Storage: 18.52
Total Storage: 20.94
Available Memory: 27.17
Total Memory: 48.68
Not much different from Gnat's ROM.
I havent really played around with it yet so cant say what's missing or any bugs around.
The significant additions (as far as i am concerned) are the modified *.cpr file (that control how the homescreen is displayed) and the bronzeres.dll which contains the pics for the homescreen. This bronzeres.dll had more than 100 pics instead of the original which only had about 80. (I found this file elsewhere in this forum; thanks to the contributor). If you want to view the content of the bronzeres.dll, download PE Explorer and install to your pc (please google for it).
Attached are the pics.
THANKS AGAIN TO ALL!!
Sorry Guys, i was sleeping..
Illi, Good that you solved your problem and thank you very much for your screens.
I dont know really what for bugs have gnagnosplat's rom. Perhaps someone can write that here and i would show to fix that.
What i can say is, that the rom very fast and stable is
But what i doesnt make in that rom is, to install other software. This rom must remain clean. The full rom, would have the tools that you have postet in the other thread.
Blackdragon
Problem
I think most, if not all, bugs in GnatGoSplat's ROM is with this ROM too. Eg. WMP full-screen does not "sick" after a few seconds it reverts to default screen. Not only that, I am being "kicked" out of applications unexpectedly. The appman.exe seems to have shortage of memory to run programs.
System error:
"Cannot start 'appman.exe'. A critical component is either missing or failing due to low memory"
So, I would suggest those who intend to flash this ROM but havent done so, please hold back. Do not flash yet until I am sure its not the ROM but my apps installation. BTW I didnt install that many and they were the same apps that I installed when I was with Gnat's ROM.
@Blackdragon_860 - I am sorry, looks like you need to get back to the re-cooking. But we must determine the problem first. I am still testing.

How to Restore encryption file???

Hi Guys...Please help me
I have Very2 Trouble....
Im using Tomal ROM for My Uni....But Im Set encryption File in Setting/system/Encryption
My Uni ReUpgrade With EF 2.40 Last night.....Before Reupgrade, I Backup System using spb Backup, i save to storage card. After Reupgrade,file Backup Can't Acces/open...
How to Unencryption this file???? Because All file in program file,backup file can't Open...
I'm sorry but as far as I know there is no way you can restore an encrypted file. When you reflash ROM your Uni has different encryption - as if it were a different Uni. Obviously, the point of encrypted files is only the originator can read it. I don't think even reflashing with the original ROM will allow, as the encryption code will be changed again.
You would have had to copy your SD card to your PC using ActiveSync before flashing ROM.
Today I reflash Again using TOmal ROM...
But No Can Find Solution....
SO Sad...
Sorry ajie,
I have had a further investigation, and it looks like Microsoft are putting a stronger message when ticking the 'encryption' box. However OEM don't seem to be passing this on. (Perhaps a small note for all cookers?)

[Q] Where are the Pros at?!

Hi there,
I have a few questions and after trying the search function, I decided to start a new thread!
I am used to using Acronis True Image or Ghost on my PC, to backup entire Operating Systems. Is there anything like that for Android?
I would like to be able to backup a ROM, install another ROM, and then, if i want to, switch between them...
After installing a stock ROM again, I was surprised to see that it wasn't that bad at all...it was actually relatively quick. Why shouldn't I just remove all the crap of a stock ROM and use that instead of using a custom ROM?!
thanks,
Georgios
Yes inside of cwm there is a backup mode you can use. It does exactly what you mentioned just have to make sure your not hopping from a rom that's incompatible with another rom/partition etc,and you'll be fine. Other than that its your choice on how you like your phone. Me personally I would not of kept this phone without our devs on here I love their Roms and kernels. Imo
.......infuse.....Infused....infusion.........
Backing up ROMs
Don't know about backing up the ROM, but you really should wipe your phone before installing a new ROM unless you KNOW otherwise. Afterall, each ROM will re-write parts of your phone's operating system. Wiping before each install will ensure you start out clean. There is a program called "Odin" that will make this an easy process. There are different versions of Odin and each one can perform different tasks, so read up on using it BEFORE you jump in head first. Odin can be used to install individual files, like kernals, or master clear your phone or it can take your phone back to stock. Most ROM devs will include in their instructions what you need to do to install ROM. Although I believe it's hard to brick the Infuse (unless you jump in head first), IT CAN HAPPEN!
Read Read Read!
Regarding restoring your programs to make it easier, Titanium Backup is probably the best at backing up your programs. Afterall, restoring ALL your programs can cost you alot of time if you don't have a program like the ones you use on your PC.
Note that you must pay for the Pro Titanium Backup to be able to use the "Batch" feature. The batch feature will allow you to reinstall selcted programs automatically without any interaction. Without "Batch", you will have to keep pushing the install button for every program you want to reinstall THE PRO VERSION IS WELL WORTH THE SMALL AMOUNT YOU PAY!
For me, installing ROMs is kind of an addiction. Installing the ROMs are fun. Granted they take a little time, but..........
Sorry to be long winded as I didn't know whether you were asking as a newbie to the ROM world

Thanks for the fast reply! I actually tried to create a backup/restore with cwm. it worked fine. However, I didn't try to bring back another ROM yet. I wonder if the current backup is going to be deleted if you install with cwm another ROM?! With Acronis/Ghost you install Windows, create an Image to another partition or hidden partition. You can then install another version of windows and do the same thing, create the Image, store it on another partition and you can then bring back which one you like!

that would be difficult for most users, im sure you'd have to get into the recovery image and edit it a bit. you may just be able to copy the backup to the external card manually.
im a fan of stock-ish roms as well but im also a flash junkie, seems deodexed roms run a little choppier at times, i cant verify this but stock phones in the store never seem too laggy despite all the memory mods and "lag-fixes" we use around here. i think it may also have to do with the build environment for the custom kernels, some just work better than others despite similarities in the feature set and shared sources among the community. i reember a while back when i got my captivate a developer had a thread discussing toolchains and there effect on wakeup lag which was an issue early on in i9000 development.

Recover datas after rooting my O+7 pro

Hi,
i had root my O+7 pro and didn't seen the warning that it's wip datas ...
is there any way to recover theme?
Thanks a lot in advance
You can try disk recovery from the play store and give it root permissions, but I can't say if it will recover anything. But to be fair, there were warnings given when unlocking the bootloader, etc about the wiping of data. So possibly a hard lesson learned
Always backup... Backup... Backup... Even if just doing an update. Since you are rooted now I would get titanium backup and do a backup before any update or flashing that u r not comfortable with and back up to Google drive or push to an OTG also back up ur sdcard files by manually moving to an OTG or use twrp to backup data to an OTG... Preferably before u set a pass code or pin securities. Hope u can recover bud.
i'll try the first solution.
in all the case i'll use a good backup solution after that. and i know, i usualy alaways backup but idn, this way my brain had decided it was useless *facepalml*

Maybe you can dumb and pull your userdata partition to an .img file via adb to your pc and then use softwares like recuva to recover data on windows, i don't guaranty it will work , but it's Worth the shot, i tried it one time when i had the OPO (i changed to f2fs partition without backing up and lost everything) annnnnnnndddddd...... no i found nothing lol, but maybe you can find since it's a different type of format i guess" but worth a try

There is no data found because it is encrypted.
All phones that ship with Android 6 or higher have user data encrypted by default from first boot, without the user enabling encryption.
This is intentionally designed to protect against data recovery by an attacker.
Even if you don't use a PIN or password, Android creates a random encryption key to secure the data. When the phone is wiped the keys are deleted making it difficult to recover data without said keys.

Not possible. The encryption keys are protected by what is called hardware-backed encryption. The Snapdragon chip binds the keys to a specific device so the data can't just be copied to a computer and recovered. It would take a major security flaw (that hasn't already been patched) to get through this system.
It is designed to be very secure. It is also used to protect fingerprint data and Netflix DRM.
