[Q] Factory reset for warranty - Transformer TF300T Q&A, Help & Troubleshooting

Hi all, i have 8 days till my warranty expires, but before i return it beacuse bluetooth problems i must factory reset it.
I rooted my device almost 2 years ago i dont remember with what procedure but i remember i used Voodoo OTA root keeper to keep my root for updates until i am now on 4.2.1.WW
So i need help with full factory reset so there is no evidence of rooting, i didnt unlocked bootloader so i know that is possible.
thx in advance

Shouldn't a factory reset from the device menu be sufficient? Just make sure to disable Voodoo. You could also reflash the Stock ROM using the built in recovery (without unlocked bootloader)

[Q] Unroot for warranty?

Hello all,
I have searched the forums quite extensively regarding unrooting the G2x for warranty purposes. I used SuperOneClick to root my phone last week before my phone began to experience reboot issues. I do not have any custom ROMs or anything of the sort on the phone, just the basic root. I used SOC to unroot the phone but I was wondering if there was any further procedures needed to have my phone acceptable for replacement warranty. Should I do a basic factory reset?
Any suggestions would be greatly appreciated.
Thanks in advance
If all you did was root the phone, then unroot and factory reset will be all u should do.

[Q] Xperia Play OTA Updates

If rooted would I even need the OTA updates? Not "planning" on changing the ROM just rooting device for superuser rights. Does that still void warranty if ROM is not changed? I couldn't find anything on Rooting/Void Warranty on Verizon website..

technically, the mere rooting voided it. my opinion is, if you can hide the fact you rooted it successfully, obviously any problems cant be due to root access, considering the root should be wiped if you use the "repair" in pc companion after it says "your phone is up to date" and the rom reinstalled, so any further problems must be hardware. therefore, root must not be the stem of the problem (unless you over-clock too much with a diff kernel and burn out the cpu or something.) so my suggestion is, use "CWM-installer" or whatever it is (the app specifically states it is for xperia devices) and back up your phone now. just in case you need to use the "repair" so you can get everything back. i havent done this yet, but from what i understand, this should work with even a softbrick. just make sure you unroot BEFORE you take it to verizon if screen breaks or something. just make a backup, remove the sd, and factory reset it or use pc companion repair and say you had software problems recently and reset it to fix it, then the stupid thing had to spite you twice and break physically too! lol. anyways, best of luck!

[Q] Root and Warranty

First of all I realise there are probably a lot of topics about this, but search is temporarily unavailable apparently. My question is, how does unrooting work after you root your phone? Can you get your warranty back if, for example you just factory reset it from settings or do you need to unroot it via a program or adb, or is it even possible to restore the warranty as if it was unchanged?
Thanks.
You can always restore warrenty if only ROOT
Thanks for the answer, that's good to know.
Edit: What is the best method for the XL?

[Q] Nexus 5 fully wiped (system, data...), bootloader Locked

Dear all,
I am new on Android, the Nexus 5 is my first android device. I freshly come from a 5 years old iPhone 3G.
2 Weeks ago I unlocked the bootloader of my device and rooted it following the tutorials provided by the XDA community without any problem.
Today, I saw that the OTA to upgrade from the Android version 4.4 to the version 4.4.2 was available directly from the device.
Since I did not want this update to be a problem with my rooted device, I downloaded the following apps: BootUnlocker for Nexus Devices and OTA RootKeeper (I do realize using RootKeeper was stupid since anyway the last update was released on July 25, 3 months before KitKat...). But anyway, this is what I did. I used those apps to Lock my Bootloader and unRoot my phone, thinking that this will reduce the chances of potential conflict with the OTA update.
Afterward, I downloaded and tried to instal the OTA directly from the Nexus 5. It ends up that I got stuck on the recovery menu. It was then impossible to get back on android and I did not know what to do.
This is where I did something totally crazy. Usually I spend time reading tutorials and finding information before doing anything that I do not fully understand. But at this stage I simply thought that the update could not properly instal due to the root. So I went on Advanced Wipe, I ticked all the options (data, system, Cash, Dalvik... all of them), and wiped the device.
As a result, my Nexus 5 has currently a Locked Bootloader and no OS installed. This means that I cannot activate the developer menu (no OS) to tick the option USB debugging. Thus, I cannot unlock my bootloader and in consequence I cannot instal the factory image and get back to stock.
Please, If you can give me some advice, explain me how can I unlock the bootloader in these conditions. Let me know... I really don't know what to do now.
PS: sorry my english is not perfect but I do hope you clearly understand my problem.

You've got it all wrong. You do not need USB debugging to unlock bootloader. to unlock bootloader you must use FASTBOOT commands, which means you MUST be in the bootloader itself. USB debugging ONLY works in android.

Dear RootSU,
So this means that I am not stuck at all and that I am simply limited by my current knowledge about android?
If this is the case, then "alleluia"! I will document myself to be able to fix this thing.

Pretty much
You should be able to unlock the bootloader as you did before.
Boot phone to fastboot mode, download fastboot and adb kit to you computer... it can be found here on forums easy, and in comand line to unlock bootloader you need type "fastboot oem unlock".
More complete guide you can find here http://forum.xda-developers.com/showthread.php?t=2507905 =)

It's ok now!
As you said, I could unlock the Bootloader the same way I did before. Then I install the factory image 4.4.2, which I rooted directly.
Thanks a lot RootSu, you've shown me my mistakes and put me on the way to fix my problem.
Thanks also for your concern Biggreen. =)
Problem solved!

Dear RootSU,
One more question, could you explain me why I got stuck into the recovery menu when I first tried to update via the OTA? Will I get the same kind of problem when I'll update with the v4.4.3 in the future?
Thanks

I am not sure on the extact reason. OTA itself will not install with a custom recovery. You have to download the OTA and boot to recovery then manually flash.
There is a good "OTA Helpdesk" sticky thread in general you should read as theres lots of advice there
hi there...i've got the same problem... i wiped everythink and now i'm not able to switch on my phone....i just want to get out of this somehow...i'm very much new to this and i just want to get my stock android back that's it...somebody please help....
Do you see the battery icon when you connect the phone to a charger? Does the LED turn red when you connect the phone to a charger? Maybe leave the phone connected for a couple of hours and then try to power on?

Xperia XA hacked. Worried about ROM virus.

Hi. Hope some Sony Xperia guru can help me with this.
I recently went on vacation and left my Xperia XA F3111 at home. Some a***hole had access to it for over 2 weeks and installed some malware on it. When I found out I factory reset the phone, but I really want to restore the stock ROM too in case he has flashed the phone with a malware-infested ROM which will survive a reset.
My problem is, the phone settings say "Bootloader unlock allowed = No". The guide here on XDA Developers say that this setting means he could not root the phone. My first question is, would this setting have also prevented him from installing a custom ROM?
If that would not have stopped him, are there any step-by-step instructions as to how I can reinstall a clean stock Sony ROM with that bootloader config setting in place?
Thx. D.
Hi, factory reset of the phone was the best choice. You don't need to worry about the integrity of the system as long as your bootloader stay locked so you don't need to flash it again.
For the malwares it's probably coming from crappy apps, for sample: https://www.google.com/amp/s/bgr.com/2018/11/25/google-play-store-apps-removed-malware-found/amp/
@rrvuhpg
Many thanks for your answer. The phone says the bootloader cannot be unlocked, but does this mean he could not have unlocked it, flashed a virus infected ROM and then re-locked it?
I mean, does that config setting mean that nobody can ever unlock the bootloader and change the ROM?

Yes exactly, almost nobody can corrupt the system (for now). If one day you see a TA dumper for locked bootloader on Nougat or a root exploit it will mean that your phone can be corrupted.
