[Q] factory reset after modifiying system files ? - General Questions and Answers

hi
i iv rooted my Galaxy grand neo gti-9060 with Vroot
i used some (root) tool to delete bloatware apps and i modified the system's resolution,
i wonder, if i do a factory reset from the setting in the phone menu, after all of that, what would happen to the phone
can i do a factory reset without being afraid from bricking my phone
if so, any advices ?
btw i searched, all users asked same question, but am the only one modified the system files i think

@manhab, it won't brick you, but since it only wipes the /data partition, you won't be 100% back to stock.
To really do a full wipe and revert to stock, flash your device's stock ROM in a custom recovery.

factory reset?

I have a question that needs an answer
I installed VU on my inspire 4g. i have all my contacts on it and such . however i am giving that phone to my wife now. can i do a factory restore and it will restore it to the way VU was originaly installed without my apps and my contacts?

Yes you can, just either do the wipe user data option from clockworkmod recovery, or do a factory reset from the options.
thank you !

No don't do that. Custom roms install things that will be deleted if you factory reset. Then it will bootloop or be missing apps do a master clear and then reflash the rom
what is the master clear? how do you do that? and you say flash the ROM, do you mean the stock ROM from HTC?

That depends on which rom she wants. If its her first android rom and you want to shoot for a stock feel then yes do the stock HTC rom. If she is comfortable with a custom rom then do a full wipe and then reinstall VU. Custom roms install things to the data partition which gets wiped when you do a factory reset causing apps to force close or not be there and depending on the custom tweaks it can also cause a bootloop at times.

How can i return to the stock firmware of Nexus S 4.0.3 ?

Hello.
I have root my phone to a custom ROM.
But i want and i prefer to return to the stock one.
Can someone tell me how to do that ?
Thank you,
in advance.
In this thread, just click on the model phone you have. Back everything up, obviously (nandroid and titanium backup might be a good idea), fully wipe (data/factory reset, format /system, format /boot) and flash your particular Full OTA file. Now you'll be on a 100% stock ROM, and it WILL replace your current bootloader on each boot.

[Q] noob question on factory reset vs flashing stock

Hey guys, its my first post and I tried searching the forums and google for the answer but didn't seem to find any.
I have the s3 SCHi535-VRLHE firmware and rooted my phone with through Noxious Ninja's walkthrough. During the process (Win7 4bit) after installing the drivers I let windows update update my drivers and cause a conflict with the 1.4.6 drivers. Should of stopped there but went through with rooting anyway (I know I'm a noob).
I have not flashed any custom ROMs after I rooted so my question is what's the difference between a factory reset vs. flashing the stock rom back onto my phone now?
Looking forward to reading and hopefully learning something from your responses!

A factory reset will just clear out your user data. You should probably put a stock ROM on your exSDcard, boot into recovery, wipe data, then flash the ROM. That will put you back to stock. Though you'll still be rooted and unlocked.

If I already did a factory wipe/reset is it safe to flash the stock rom onto that or do I have to root again?

[Q] Factory reset on root with roms

Hey everyone, reset question for you. If i do a factory reset on a rooted/unlocked GS3 with the stock rom, will i 1: be able to keep root, and 2: will the rom backups on clockworkmod still be there?
thank you for any help!
Using CWM Recovery, 1 Yes. A factory reset only deletes data and cache files. Data being your apps and settings. 2) Yes, CWM doesn't automatically format either SDCard.
To answer again in different terms, CWM Recovery factory reset only wipes /sdcard/data and /sdcard/cache. Backups are in /sdcard/clockworkmod and root is a modification in a different directory.(I dunno the name offhand)
Perfect! Thank you so much, this makes a lot of sense. Thanks for including that link as well.

[Completed] Restore OS After Wiping System Partition - Galaxy S5

Due to problems with Google Services on my rooted Galaxy S5 (SM-G900F) I opted for a reset from TWRP and it returned to a condition where after some initial screens it was just stuck at "Checking for Updates" so I went back into TWRP and told it to wipe the other partitions. Whoops - now I have no OS (I was sort of assuming that the factory reset OS was somewhere else)
Which is the stock ROM for my Region - UK, unbranded - where do I get it from and how do I load it using Odin and/or TWRP?
TIA
Hello,
Did you make a nandroid backup of your stock ROM or a nandroid backup of a custom ROM if you installed one? If you have a nandroid backup of either of those then you can restore them in TWRP by choosing the restore option and then your nandroid then swipe the slider at the bottom of the screen. If you installed a custom ROM at any time before this and you still have the ROM file then you can reflash the ROM and Gapps.
If you don't have a custom ROM stored anywhere but can still get to recovery, then you can download any of the custom ROMs compatible with your device and a Gapps package that matches it and put them on your extsdcard then boot to recovery and flash the ROM and gapps, do the normal wipes in recovery after flashing, the normal wipes(wipe data/factory reset, wipe cache and wipe dalvik cache), DO NOT CHOOSE THE ADVANCED OPTIONS THAT LET YOU WIPE PARTITIONS.
Check this thread to see if it is your stock firmware, it SHOULD be but double check first, it also has instructions for rooting again and installing recovery.

If that doesn't work then go to Sammobile.com and search for your stock firmware by using your device model number.
The firmwares can sometimes be found at samsung-updates.com also.
Find the right firmware for your exact model number and flash through Odin.
For further assistance, post your question in the forum linked below.

Good luck.

Sadly not - wasn't expecting to need it, thought it would revert to factory default - I have Titanium backup of apps and data.
I am hopefully a few minutes away from downloading the stock ROM and hopefully can reflash that using ODIN.

Making nandroid backups in recovery is the most important and valuable function of custom recovery, flashing ROMs is its' secondary purpose Android is not like PC with a recovery partition that restores a factory IMG, on PC that factory IMG is stored in a recovery partition. The factory reset feature in stock android does not restore an IMG, it deletes all data from the user partition and leaves everything in system partition the way it is, if you delete a system app and then do a factory reset then you will still not have the system app that you deleted. Anything you modify in system remains the way you modified it if you use the factory reset option. You should only use the factory reset in recovery, not the factory reset in system settings when you have a rooted device with custom recovery.
I'm sure that when you found the recovery, the directions had to have mentioned making a nandroid backup of your stock ROM before flashing anything, your present situation is why you do that, so that if anything goes wrong then you can easily restore to the one ROM that you know for sure works with no issues.

I installed the TWERP recovery as part of the rooting operation and I didn't pay any attention to the backup option - I thought that's what Titanium did.
I am learning and will make sure that I take a Nandroid backup once I have it back up and running. Life would be so much simpler if only Samsunng didn't stuff their 'phones with bloatware that can't be deleted in stock mode.

Titanium backup can only backup data that you installed or downloaded, it does not backup anything that comes on the phone itself, that is what custom recovery is for.
When following guides to mod your device, read and understand ALL instructions before you even make the first move to touch your device. Get used to being thorough about reading and understanding first or you'll end up in a mess, possibly even hard brick your device, all it takes is one wrong move. Not all mistakes are fixable with android devices.
