[Q] Do I Have To Factory Reset Before Updating My Rom - General Questions and Answers

Hi Guys, new to the forums with my first time post. Got a Q here which has likely been asked and answered before, but there is way too many pages for me to search
Anyway, question;
I'm currently using Omega ROM 4.2.2 on my Galaxy s4 and want to update it to the latest version. Can I simply download the new version and install it over the old one or do I have to factory reset first or take any other steps?
Thanks in advanced.

Hello @nability you do not need to factory reset your device to install the ROM. In your case you're just updating the rom. But if you're moving to a different ROM you'll need to factory reset it. But again since you're just updating to a newer version of your ROM, you can simply download and install over it. Just wipe the "cache".

Brilliant, I was hoping you would say that
Thanks for the quick reply.

Sorry guys got another question that I just need to be sure of.
When I update the ROM, is that the only update I will need to do in order to get support for 4G LTE?

[Q] Samsung Galaxy S HardReset

Hi,
I upgraded my Samsung I9000, from Éclair 2.1 to Froyo 2.2, with Odin, (everything is working fine), but...
My question is;
If I do a Hardware Reset does the phone downgrades to is factory default, in this case "Éclair 2.1", or it stays with the last OS installed?
Does anyone knows what happens??
Cheers,
Striken
A hard reset is different than a master reset. Hard reset only entails removing the battery from the device.
To answer your question, once flashed with a ROM, performing a MASTER reset, will bring the phone back to "factory" defaults, i.e. just like it was the very first time you booted it AFTER installing the custom ROM.
Hope that helps.

Thanks Man,
You are talking in a Master Reset, how exactly do you do that?
When I did a software reset it erases everything on the phone, contacts, apps I installed, everything except what belongs to the Rom I installed. Also the phone stayed like when was installed for the first time...
From what I've read an Hard reset puts the phone to is factory defaults, but when I did a soft reset it also stayed "brand new", like factory default.
My question is: does a hard reset erases the rom I installed and puts my phone like it was before I upgraded with Froyo 2.2?
I never heard anything regarding a "Master Reset", can you explain me more?
Thanks,
Striken
Also interested in learning how to Master Reset before playing with ROMs.
Bookmarked for later, thanks!
Hi Kops,
If you also learn anything about it please post it here ok?
Thanks
I believe you can find the stock firmware for your phone (2.1 or 2.2) and use ODIN to flash to that. By doing so, you will revert to 100% stock settings, no root, and no proof that you've flashed your phone at all.
In my opinion, this is your best bet for a "full reset".
When you flash a new firmware, the firmware is permanently installed. Performing a factory reset will NOT revert your phone to its older version. Only a reflash will do this.
Factory reset only resets things that are stored in user data space. Such as your contacts, custom settings and any apps that you have installed (not counting those that Samsung/Google have put into the system)
So there you have it. You can safely perform that reset if you want.

Thanks for the help guys,
So, there's no difference between a soft and hard reset? Or is the factory reset an hard reset?
When I did a factory reset it erases everything and restored the phone to is default settings.
So, the only way to put the phone back like it was when I purchased is installing Eclair 2.1 again...
Thanks,
The only way to get 2.1 back is by reinstalling an official samsung firmware. Yes. If you have an official samsung firmware though, the phone is as it should be.
A soft boot is generally where you send the device a reboot command or turn it off and back on. A hard boot to reiterate generally happens after the battery is removed and reinstalled. This is not what is known as a factory reset and will not modify anything.
A factory reset formats the userdata and cache partitions and resets all settings to default including deleting any apps that were not installed on the factory firmware.
I hope this has answered your question.

It did, thanks.
The only problem is that I never found an official Samsung firmware, in this case the Eclair 2.1 from Vodafone.
If you know any site that have that Rom please share it
I would like to have it so I can restore the phone in an urgency...

Don't want to be a pain, but just one more thing if you or anybody knows...
When I both my phone it came with Eclair 2.1 from Vodafone like I said.
You presented me with a page that have the 2.1 stock Rom from Vodafone, but, originally the phone had a Vodafone startup animated logo.
Do you know if the rom in that page has that animation startup?
Thanks,
P.S. One more thing, when I said that I didn't find anything in that site I was mistaken, it was not that website but samfirmware.com website.
Thanks again,
Its a stock rom. Just like the one that shipped inside your phone. It will have all of the features of the ROM you started out with.

You can remove all user data that is located on internal memory by typing *2767*3855# in dial pad and NO it won't downgrade to previous firmware.

[Resolved] [Q] I've made a mess of my Nexus S...

Hey guys,
This is my very first post, just to let you all know, so please have some patience! Thanks!
Anyway, so I have a Nexus S 3G (Canada) and I have rooted it, unrooted it, installed roms and everything. I works...for the most part. It's giving me all sorts of different little errors and what not. So I was wondering, how can I COMPLETLY start ALL OVER, as in, factory new, like when you buy a new phone (without the carrier stuff). I wanted to start fresh, fresh out-of-the-oven kind of start, do you understand what I mean? FACTORY FRESH. Thank you all so much in advance!
well download your phone's stock rom and of course unroot it.Regarding the stock bloatware you can modify the custom rom by going in system/app and deleting the apps you dont want to be installed

Thanks for the reply, I've already done that, and I'm still getting errors and other weird things, like not going out of airplane mode, failing to download the OTA 2.3.6 Update (I'm on stock 2.3.1 unrooted, I think), and I don't know if this is normal, but ClockworkMod Recovery is still there. Am I still rooted or something? Plus, when I try to flash a restore, from let's say Gingerbread 2.3.6 Stock, it says MD5 mismatch! How about if it's an ICS AOSP Build, it gives me the normal white Google logo like normal, but then just stays stuck there.
Is the anyway to erase EVERYTHING and start over like NOTHING was ever done to the device? Like when they are first distributing the the device and no one has ever touched it? Is there anyway to do just that?
There is a difference between being "rooted" and using a rooted ROM. You could be using a non-rooted ROM, and your phone can still be "rooted". The first step in rooting a phone is changing SECURITY-ON to SECURITY-OFF. If you REALLY want to go back to when you first got the device, you will need to find a way to turn SECURITY from OFF to ON. When it is off, you are able to access the bootloader, in turn allowing you to install a recovery to install a ROM with rooted permissions. I think the best way to go back to stock would be for you to first download the latest OTA update for your device, do a FULL WIPE of everything on your phone thru recovery (data, system, cache, dalvik cache). Then installing the latest OTA. I do not think however, that this is how you turn your device S-ON.
I hope I've been of some help.

Thanks for your excellent reply, but I have also already done that, EXACTLY that, multiple times too. Dalvik, battery stats, factory reset/delete all user data, wipe cache partition and fix permissions. What else is there left to do?
Thank you all so very much!!!!

re: i flashed gapps
Sent from my Nexus S using Tapatalk 2[/QUOTE]
I flashed a gapps zip from the site you linked me to and now when the phone turns on it says setup wizard is not responding and give me the option to force close. Nothing happens from that point its just stuck in a force close loop. I hope to god i didnt brick this thing. Is there a way to fix this problem? I didnt backup before flashing gapps and ive tried to restore the phone and wipe it clean but no luck. Any help would be greatly appriciated because i just got the phone, mainly to use it as a fun project seeing as smartphone customization has become my new hobby, and Im usually very good at it but now I am just afraid ive bricked the phone and I bought it unlocked so i paid a fair amount of money for i. Please help if there is a solution. Thank You,
Do you still have access to CWM? Can you make a clean install of any ROM? Wipe dalvik, cache, factory reset, format boot, system, data, cache and install ROM.
Download another ROM (and follow instructions from OP) which is not the one you initially had problems with (or download again - might be a corrupt zip file).
Thank you

Thank you very much, I followed and executed your instructions and now im running ice cream sandwich 4.0.4. not bad from going from almost a bricked phone to running one of the best versions of android. I downloaded offical roms this time instead of custom ones, first a version 2.3.4 and a 4.0.3, flashed the ics rom first and worked like a charm. Thank you very much, even got an update 5 min after i flashed the rom. You saved me 200$ and the embaracement of having a worthless phone. Im sure ill have more questions in the future, so glad there are ppl out there with the same passion for smartphone customization that i have. Much obliged. Omar

[Q] Upgrade CyanogenMod 10.1 with goo.im not working

Hello Everyone,
Im new to this forum as a poster, I do have read quite a few tutorials on here on how to unlock/root/s-off my device but now Im stuck again and can't seem to find a solution.
I have a HTC Sensation Z710e and I'm running CyanogenMod 10.1-20130309-Albinoman887-pyramid. Now whenever I watch a movie I there are no troubles BUT when I scroll in the movie or pause it or whatever I get an error. I looked it up and found out my version is an unstable one. So a friend of mine explained to me I could update via Goo.im, and here's the problem. It says there are no updates for my device even though that friend of mine updated to 10.1-20130601-Albinoman887-pyramid in the same way.
I did get a message like 2 weeks ago there was an update available for my device but when I clicked the notice nothing happened.
Now my biggest question is, is there some way I can download an update zip in stead of the 10.1-20130601-Albinoman887-pyramid Rom and have to start all over again with all my apps, or am I just ****ed and need to start backupping what I want to backup and start over again?
Thx for any and all insights,
Marius
well if the rom is just an update from the same rom, get it from another repo (download it from your phone or pc) and flash it with TWRP/CWM
It should work, I've done many rom upgrades without wiping my system.

So you're saying I should just "install from sdcard" with my 4EXT and it will not wipe all my settings? Even though its a completely "new" ROM but just an update of the one I have right now? I dont have to invoke something like "update"?
I did already download the file with Goo.im (that did work ) and it was about 157mb, that gives me the feeling its a completely new ROM, that's why Im a bit hesitant
Thx for the info though
MariusJP is right, there's no need for a wipe when you are flashing an update, but it may depend from ROM to ROM and from update to update. Just flash it and look for problems. If there are problems you'll have to wipe.
You should do a Backup via CWM before flashing any new software especially when it's not a stable one.
Flashing this update won't wipe your settings and data.

Can't get 4G signal?

Hi everyone,
I'm currently on ViperOne ROM (the latest version) and it's been going great for me in general, but the biggest issue I'm having is that I can't connect to 4G! I live in a 4G area, and I've done plenty of traveling around the country to different 4G regions, but still haven't gotten it to work. Did I possibly break 4G on my phone? Thank you so much for your help.

Install stock recovery. Then factory reset. 4g should return.

I'll try that for sure, but would that be the only way to go about fixing it? I'd hate the idea of wiping my data, switching ROMS, etc. but if it's the only way to restore 4G, it's absolutely worth it. I thought that perhaps if I reflash the latest firmware, that might also do the trick?

In recovery, try clearing the cache (TWRP->wipe->advance wipe).

I've never needed to try this to find out for myself but I've had this question for some time now:
Would one really need to install JUST the stock recovery to perform whatever factory reset that only stock recovery can perform? If I ran into this kind of trouble in the future, could I just flash stock recovery, factory reset, flash twrp, go through initialization (due to wiped data) and consider it a fresh start my custom Rom?

Yes you could. As long as its stock recovery that does the wipe.
