can a patched switch be reverted to original firmware - Nintendo Switch Questions & Answers

Hello all! if there is a pre existing thread for this i would be more than grateful for a push in the right direction but i checked and could not find anything related. i have just purchased a switch today 2-14-20 and im holding off on connecting it to the internet to avoid firmware updates that will prevent jailbraking the device, my question is: is it possible to back up the original firmware so i can update to use the e store but if i decide later to jailbrake i can revert back or is it once updated the device is patched forever? any information is appreciated thanks!

If you don't burn the efuses then yes you can restore the backup and it would boot which would mean never updating ofw and only updating emunand with fuse burn prevention on.

Will updating my firmware erase my phone?

I have the option to update my firmware in Keis. I know this is probably a stupid question hence why I can't find an answer anywhere. Will updating the firmware return my phone to stock?
I haven't modded it loads but if so I need to leave aside more time to do it so I can put everything back on.
If you are on stock you can update without loosing anything.
ps: there is a Q&A section
Do yourself a favor and always backup your data. Its easier to save it, than to download it all over again.

Question on upgrading to 5.0 from 4.4.4 when i was rooted.

hey guys i recently rooted my phone and then saw that 5.0 came out i wasnt able to find any reputable info on un rooting my phone so i could do the over the air update from verizon. however there was 2 updates available from OTA , one took me to another version of 4.4.4 and un rooted me. my boot screen still says custom but i no longer have root. however the ota 5.0 keeps failing. i figured maybe i can up date manually but the only site that has 5.0 for dl is sammobile and their site is down. all the other sites i found seem to be scams or want you to pay for faster dl. i dont care if i even have root any more i just want my phone on 5.0 with out loosing all the data on my phone. does any one have a link for instructions to do this? and a working link for 5.0? thanks
bump for help
Can you not boot into custom recovery twrp/safestrap? I Just re read your post, I'm assuming you can. So do that, and make a backup of /data. In addition it wouldn't hurt to use a usb drive or computer to back up any important files.
You say you want to be able to update without losing your data, I don't know if that's possible.if that is a real problem for you,I'd advise against modifying your phone in the future.
You didn't say why the update is failing, what is the given error message? Have you read the Verizon s5 forum?

(Soft?)-Bricked My S7 with a Flashfire Update, Need Help to Fix It?

So I've been rooting me phone for a while and have managed to never f*** up, till now, and I sincerely hope you guys can help me.
After rooting my S7 a while back, I just recently noticed SuperUser telling me that I didn't have root anymore, so I decided to follow these instructions to re-root my phone:
https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039
I successfully followed all the steps to get root, but when I opened Flashfire it told me I could install a new update while maintaining root, so since my android is at 6.0.1, I did that and it bricked my phone.
On boot it says "Startup Failed - Use the Verizon Software Repair Assistant . . . " and on top it also says "Custom binary blocked by SECURE BOOT." I have tried going into recovery mode and deleting the system cache, but that doesn't do it. So is there any way to get the phone to properly boot while not deleting my data? I was rooting my phone precisely so I could use Titanium Backup again, so I don't have any backups stored anywhere. I have heard that flashing a recovery image with Odin can work, but would that delete my files? Someone please lend me your expertise.
My phone is a Verizon S7.
Fixed
I am surprised that no one responded to me, but what's important is that, miraculously, I managed to un-brick the phone myself without losing any data! What I did was, as my last hope (since Odin wasn't able to flash the stock image, a la the traditional soft-brick fix), decide to follow the on-screen instructions my phone was giving me and to download and run something called the "Verizon Software Repair Assistant," which can be found in the top google results after searching for the quoted name (xda doesn't let me post the link).
After putting my phone into download mode, I plugged it in, ran the software and let it work overnight. Checking on it in the morning, I found my phone, not only completely functional and working, but updated to Android 7.0 (it was 6.0.1 previously before the failed Flashfire OTA update) and still holding all of my data intact.
So, the interesting thing that I learned is that flashing to stock via Odin to fix a soft-bricked phone should not be the default resolution for potentially most people, as the carrier's default (in my case, Verizon's) repair utility managed to completely fix my phone without any side effects or data loss.
Is there anyone who could chime in on why the Repair Utility did not wipe my phone's memory, even though it warned it would?
**Note**
Verizon links to the Windows version of the repair assistant on their site, but to get the Mac version (which I used), the only way you can get it is by changing the end of the url they mention within the thread from "Win" to "Mac."
Pleased you managed to fix it, and thanks for posting the method for others
As for replies, if you stick around XDA you'll see replies can take days sometimes, patience is the key here

I guess I am not acquainted with this forum enough then, thanks!
Most likely the cause of the fault would be updating via FlashFire and keeping root. When the update was flashed, it most likely flashed the stock kernel and patched it for root, which is not a compatible root for our devices. Flashing the root kernel with Odin probably would have made the phone boot normally.

Backup options for Zenfone 3, please help

Hello everyone. Looking for help in backing up my Zenfone 3.
Reason is, I must send my phone for warranty due to a hardware issue and even though I asked ASUS NOT to update my firmware (still have the original firmware), I have a bad feeling it will get returned factory reset with the latest update.
The reason is not relevant to this thread, but no other firmware past the original firmware the phone came with works properly with the 2 SIM cards I'm using. I tried.
So, is there please an option to backup my Zenfone 3 that most importantly, will keep my original firmware I have now and I can restore it if my phone will come back with the latest firmware? Something like a clone that allows me to restore it exactly the way I have it now before I must send it.
Only other possible obstacle is that my phone is not rooted or bootloader unlocked and I don't wish to do so, as I had no need, and I'm not even sure if ASUS allows that if I need to have it warrantied.
Please help? Any software out there or method I can use to just purely clone/copy my phone and be able to restore it once I receive the phone back?
ASUS do have some issues in servicing when the bootloader is unlocked but I believe the only possible way to backup your phone is by having root. Unless there is something new people came up with. You can, maybe copy your current build number and downgrade to it later by downloading the firmware file of your current build, though that was not a "clone" as you may have wanted.
Sent from my Asus ZenFone 3 Max using XDA Labs
Thanks for the reply. Do you happen to know where i could get my current old firmware? I don't think asus is making it available.
Also, would the standard backup and reset in Android not do the job? Or if they reset the phone that would be lost?

Downgrade question - possible upgrade upon restart?

Hey all,
I am very much willing to wipe my phone to do a downgrade.
I have the OP8 Pro, unrooted (never rooted/never unlocked bootloader).
The scenario I see is - I downgrade my phone to 10.15.13 (I have the INAA modell). I'm sure at some point the phone will check for an OTA.
My question - Is it all possible for the phone to upgrade itself if it restarts?
Meaning, is there a time limit that the update is sitting in the queue waiting for the user to press reboot to install? Or can I just somehow figure out a way to silence the system notification of an update pending?
Not sure if that makes sense but my hope is to just go back to 10 and enjoy certain things that just worked out better for me unrooted vs 11 unrooted until some things are ironed out.
Thanks for your time.
No you would need to initialise the upgrade, unless you have automatic updates on.
You would have seen the initial installation begin.
Least that's my experience of it. The update is stored on the phone so you may also be able to delete it.
Turn off automatically download updates.
I downgraded using the special firmware I found (couldn't find official to do it ) and then installed the official EU/UK firmware straight after with no problem
