[Q] Help in returning to stock rom

So i'm looking for a little help.
A little while back I used this thread : [GUIDE] TF300T Unlock/Root/Flash for Factory JB Devices (newbie friendly)
To help me install this custom rom : [ROM][TF300]|Mar 28| Energy™ -.¸¸.·´¯ Official JB 4.2.1 Stock or Themed ¯´·.¸¸. -
onto my girlfriends TF300T tablet
and I have this : [RECOVERY][TF300T/TG] TWRP 2.5.0.0 Touch Recovery! [2013-4-9] on there as well
but I can't remember if this was part of the unlock/root/flash process or not, so i'm not sure if it used it during the process or if I added it shortly afterword
now its been while since I have done it but then the tablet started to restart randomly while she was using it.
so I figured no biggie maybe an app got messed up or something, and so I told her to back up her pics, exc she wanted off the unit
and I could look at reinstalling the apps or just taking the unit back to factory rom
about a week later it started to reboot more often randomly
and now it is to the point where it will not make it into the rom
now I can make it into the boot selection where I can choose RCK (for the TWRP), USB, or the other 2 options
and I know I can make it into the TWRP tool as well and it does not repeatedly boot from there, so i'm sure its a rom issue and not a hardware issue, but I could still be wrong
the unit is currently charging so I have not had a chance to try for the usb connection option or anything else yet
hopefully the usb option will work so I can try to recover the pics, exc before taking the unit back to factory
now in the process I know I have unlocked the unit, I believe I have done the min root but have not fully rooted the unit if that makes sense
so i'm just wondering if I will half to fully root (and how do I do that if I do since I can't make it into a rom)
how do I clear the rom that has gone bad
how do I install a factory rom (how do I tell which is the lastest rom, and which one is needed for my unit)
and then I should be good from there
if you need any more info please let me know and maybe some instructions on how to get to that info
in the process of putting the energy rom onto it, I spent a week of reading, researching, and figuring out which way would probably be the safest for me to do, plus the easiest for me to understand
now that it has been so long I have been reading and researching again, I just need that nudge that gets me in the right direction
i'm sure i'm not the only one that has had this issue with a rom, and i'm also sure there is a guide out there already that goes over how to put it back to a factory rom
just for some reason i'm either over looking it or not finding it

Its very simple to return to stock. But first, do you have the tablets drivers installed on your pc?
---------- Post added at 06:16 AM ---------- Previous post was at 06:14 AM ----------
And do you have fastboot?

if you are talking about the android sdk tools
yes that is installed on my computer from the first time I did the tablet
and I went ahead and did the updates for it as well
and tried plugging the unit in with the fastboot and confirm it shows up in device manager

Lol okay. Theres actually a more simple way.
1. Download the latest asus firmware.
2. Extract the zip file
3. Flash it like a normal rom.
If you cant use this method then you'll have to use fastboot. Here's a link but if you need any help, just ask : http://www.androidauthority.com/transformer-pad-tf300t-restore-stock-firmware-108016/

how do I check the sku according to that guide if i'm not able to load into the android os
that only shows if you can load into the os
would the box have that?

or now looking at the options that I should assume its is a US sku lol

lol, and how do I do that using the twrp?
can't find any detailed instructions on using twrp on flashing a rom, especially the stock one
i'm sure there is a set of detailed instructions cause I swore I saw one once
but i'm not able to find it again
cause I thought besides using the install part there were things I had to clear as well for it to work
oh and yeah the download link for fastboot is no long working in the one guide you gave me to follow so not sure if I already have what it is talking about

Its simple lol. When you download the firmware from asus, its usually in a .zip form. In it, there is another zip file. Copy that zip file onto your tablet and flash it with twrp.

Yes. You have to do a factory reset first.

and how do I do that lol, and what happens when I don't do that first

is this tablet now dead since the step of doing the reset was not complete? cause now I can not access twrp and it just sits there with the asus logo and the swirling dots
when I try to access the usb option all I have is rck, android and wipe, rck just gives a failure shortly after trying

If you want to use twrp, download the us stock firm ware. when you open it, you'll see a file that looks like this: "US_epad-user-10.6.1.15.3". copy that file onto your tablet and flash it like a normal rom. haha
For fastboot, if you have the android sdk, then you already have fastboot so you dont have to download fastboot again.

if you tried installing the newest firmware, you wont see the usb icon when you press power and volume+ it automatically enters fastboot. you dont have to select anything

if you cant enter twrp, then you dont have to worry about the factory reset you can flash the stock rom using fastboot.

[Q] Nexus 5 Bootloop

So let me start by saying I am 100% a noob, and I have read many threads trying to get to the bottom of my problem to no avail. I am sorry if there is a solution for my problem somewhere, I've been working on this issue for 24 hours and have yet to find it.
My girlfriend was apparently using google maps on here relatively new phone (running 5.0.1) and it crashed. Upon restarting it was stuck on the coloured dots screen for several hours. She has not installed any third party apps, only those from the playstore and not too many of them at that.
I tried factory reset and received a bunch of errors about failing to load the E:// or something like that. The phone still would not boot up.
I downloaded minimal fastboot thinger on my windows 8.1 laptop and tried to flash a new image of 5.0.1 on it, IIRC I received errors about E:// again
Got Wugfresh NRT and tried TWRP wiped all (still saw some stuff about E:// failing to mount and such) then tried to unroot flash stock with soft brick/bootloop checked.
Still bootlooped for over an hour when I started it up.
Tried flashing 4.4.4 instead. It worked. Phone booted up. Gallery/Camera do not work however at this point. Tried updating to 5.0.1.... phone restarted bootloop for 8 hours and counting.
Flashed 4.4.4 again, Followed Full Driver Installation Guide in NRT exactly. Tried Flash Stock + Unroot with Device is on/Normal checked this time instead. Now it has been colored dots screen for about 20 minutes.
So I can load 4.4.4 but no matter how I've tried to install lollipop 5.0.1, it stays on booting screen forever.
What do?
Thank you so much in advance and apologies for being a noob.
EDIT: More googling today. Looks like my E:/Persist partition is corrupted or something, trying to figure out how to repair it right now.

If I can bet it must be a corrupted persist partition. Lollipop will not boot if its gets corrupted but kitkat will do. If you could tell what is the actual error you see in twrp or cwm recovery then we could identfy the actual problem. But I am 90% sure the mount error is about persist partition.

I'm actually looking at that right now! Downloading Java and Android SDK atm. Of course still a little shaky on a couple terms in your guide hopefully I can sort it out. Really confused as to how Google Maps on a vanilla nexus 5 could corrupt a partition like that, its all google endorsed and official. They should be fixing my phone not me lol.

Thanks for the offer. I'll try on my own and get back to you maybe tomorrow if I can't get it down.

Alright so I am definitely having problems running adb shell. even if I change the directory in cmd to my adb.exe location (android\android-sdk\platform-tools) I keep getting the error adb shell is not a recognized blah blah blah....
NVM got it working. Whenever I get frustrated enough to make a post I end up finally finding a solution.

ALRIGHT I have Lollipop up and running thanks to your guide on fixing persist partition. Thank you so much! Question: I have a nexus 5 and it does not have an sd card. I'm not sure how to proceed in doing the steps you described involving mac addresses. I did use a hex editor and make those files, but not sure where to put them in my phones internal storage, and how to direct adb to said location. Any help with that?

Just copy them to the root of your internal storage, then follow the guide.
I mean you just open the phone's internal storage from your PC and you dont open any folder. You just copy it there.
The guide is for nexus 5, but some people refer to the internal storage as sdcard too. I know it is a bit confusing. Thanks to point it out. I will make clear in my guide now.

AH I see ok I will do that tonight. Ran in to another problem though it may be related to the mac address thing I haven't done yet, not sure how that all works. The phone randomly restarts every few minutes and it won't connect to the carrier either. Also if it matters I left the boot loader unlocked for now until the phone is working properly, if that affects anything.

The lock state of the bootloader does not matter, but this random reboots after a few minutes is something to worry about. Your phone should not do that after formating persist partition.

Help, I can't get past the WIFI screen and I can't flash a new rom on this phone

Hello guys,
I need your assistance with this issue. I got this Boost Mobile LG LS770/Stylo phone from eBay and when I wiped/restored it to clean everything from the other person, the phone still wants me to enter the information from the previous person before I can use it. Of course that is not an option. I tried.
Also, since I am unable to get to the Android OS, I cannot put it in debug mode either. So I tried a few things to no avail. This is what I have done so far:
Put the phone in ADB mode via recovery - Done, but I am unable to sideload anything. I get this error.. "* cannot read 'sideload' *"
Put the phone in download mode "Fireware Update" - Done, and I can see my port as COM3, but when I run the next step, I get a message that says... "Hello, my name is LAF....." and nothing happens.
I tried using the LG one click root tool, but that requires the phone to be in USB debug mode and like I said before, I am unable to even get to the welcome screen in android. I can't get past wifi setup in reality, I can't even skip it.
I have been at this all day today. Can you please help me out? I really appreciate any help you can provide.
Thanks

You need a USB-OTG cable and some files. If you have a USB-OTG i'll reply with what you'll need to do. Also, have you contacted the eBay member letting them no they FRP screwed you and you basically own a brick now?

Also, I forgot to respond to your question. I did contact the eBay guy or lady that sold it to me, but since I'm the one that did the wipe, they are not taking responsibility and I get it. I just would like to be able to use the phone and not waste the money I spent on it. I really appreciate any help you or others can provide.

Thank you for the suggestion , but this method does not work. I have already tried this and after the tool went through all the steps, it still asks for the previous account. I have found on some other forums that LG patched this flaw a few months ago and it is no longer possible to bypass FRP Factory Reset Protection. I guess I have a rock until someone can figure out how to bypass this "Feature", which in my opinion should be illegal because it forces people to buy devices from carriers only and you can no longer sell your phone online to anyone, as you cannot give them the account.

It didn't work for me either... the last security patch disabled user from the settings menu. I did find a way after many hours of work.
Basically once I got to settings I clicked unknown sources and then enabled USB debugging and oem unlock. After that I flashed twrp and then a rooted system image. After that I used http://androiding.how/bypass-google-account-verification-on-lg-g4-g3-and-others and it worked

I honestly don't remember. I'll try to figure it out and get back to you. I think it was through the keyboard. I returned the phone already so I do t have it on front of me.
Look for anything with terms of service. Once you're on the internet you can download the settings app that everyone uses on the internet.

Web trust me i went crazy with this for 3 days. My friend gave me his Stylo from work to unlock and i had this same issue. Flashed back to 5.1.1e,i,j, using kdz files and all the exploits that these guys are using have been shut down. If your on MM forget it. The only thing that worked for me was that tool i linked in the other thread. I hope your wrong on the virus part, ill check my laptop, but your the first person to mention that. Either way i flashed back to 5.1.1 from MM, used the tool, rebooted and it worked i signed in with his gmail.

I understand and I apologize if I sounded like I was shutting your advise down. That was not my intention. I was just stating what my virus tools detected and my experience. Regardless, I decided to ignore the virus warning and let the tool run and do what the steps on the word document stated. It went through all the steps without issues and I got the same matching screen as in the tutorial document. However, after I reboot, I still get the same screen that reads, login with a google account previously associated with this device.
Now, the one piece I'm not sure I understand from your message above is the part about flashing to 5.1.1 from MM using kdz files. How can you flash the phone when you cannot get into the settings to enable usb debug mode? I have tried everything. I even downloaded a rom file image that I placed on an Micro SD card and tried running it from recovery to no avail.
Maybe you are correct and I am just missing a step. Would you mind expanding on the flashing 5.1.1 from MM part? Maybe what steps and files you had to use?
Also, I'm not sure I understand this portion of your message. You signed in with who's gmail?

Thank you in advance for your assistance.

is there a software older than 5.1.1 that can be flashed to the device?

You can use touch assistant to get in to settings and then disable all google aps, works for me on lg stylo 6.0, PaulieP he is the person that found this method

You want help with a device but you don't tell us any kind of information about your device, how smart was that? What you need and how to do it can depend on what device model number you have.

You have soft bricked your phone . The only way to fix it is it flash its stock rom. If you are new to this stuff I would suggest you to read this article carefully and if you have any doubts , ask me.

Hello everyone, I have a tablet that is stuck in recovery and looks to me ADB is going to be the only way out here. Problem is ADB isnt recognizing my device, device manager named it MTP but computer says Android. I have tried changing the USB /VID ID that reads off what is displayed in Device manager not sure if I did it right running myself crazy really, read HRS of Android info Im a noob but a fast learner especially if I get a little bit of guidance. I have tried doing every and all factory hard resets tried different flash tools probably didnt work because my computer doesnt display the correct model. Im trying to learn python at the very moment new to all of this have only hrs of experience of this all. Somebody plz be ever so kind to help me out, thanks!

Where did this problem start? Did you cause this by modifying, attempting to root or flashing the device with something that caused this?
If so, about your only option is to use your device's flashtool to flash the stock firmware. If your device's stock firmware isn't available then you might be out of luck repairing your device. If this is the case then your only other option might be getting someone that has a device exactly like yours that is rooted and getting them to pull copies of the various .img files needed for your device then using adb shell to dd those .img files on your device. But, to be honest, I don't think this is gonna happen for you. You probably will have to take the device to a repair shop. It will probably be cheaper to just buy another tablet because the cost of repair will probably be more than what you paid for the device.

Okay not sure which Flash tool to use nor get my stock rom I dread to say but i dont think there is one available. Its a generic tablet its made by Quanta. Not sure how to put it in a download mode either I assume ADB is the only way to transfer any files.

Your device probably uses SPFlashtool or fastboot.

Its pretty easy to fix a soft bricked device , even if stock rom isnt available , any rom compatible with his device can fix the issue .

To be compatible, the ROM typically has to be ported and that usually requires the stock firmware or stock source from the device that the ROM is being ported over to. 99% of the time you can't just flash a ROM from a different model number, even if the CPU is the same, there's quite a bit more to it than that. The android operating system is built for the specific hardware it is installed on, the two devices would have to be exactly the same and have the exact same components, any differences in hardware make he firmwares incompatible.
For this particular device, I doubt the stock firmware or stock source code area available, even if it were, porting another ROM wouldn't be necessary because if it were available it could just be flashed with that instead of porting a ROM.
About the only time a ROM from a different model number can be used without any porting or edits being made is when the devices are exactly the same device just rebranded with a different "name".
But thanks for trying to tell me something that you thought I didn't know, now it seems I've told you something that you didn't know.

1.Search for your tablet's root package , download it and move it to your tablet's sd card. Then enter your recovery mode by pressing power button+ Home button+ Volume button at same time for 10sec. Once entered , go to option "apply update from sd card" and select the root package you downloaded. (CONGRATS YOU HAVE ROOTED YOUR PHONE!)
2.Search for your tablet's 'custom recovery' , download it and flash it through odin tool(pc) .
3.Final Step ! BASED ON THE RECOVERY YOU FLASHED THESE STEPS MAY DIFFER , SO REPLY ME IF YOU SUCCEED IN FLASHING CUSTOM RECOVERY

Odin is for Samsung devices, not other devices.
The device they are repairing is not a Samsung device. They have this device and a Samsung device. The issue on this device occurred while they were in the process of flashing their Samsung device.
I know you're trying to help but don't post anything unless you are absolutely certain that you know what you're talking about.
In this case, you didn't and that can easily lead to a hard bricked device because they followed your instruction.
Stick to answering questions about devices you personally have dealt with, don't go assuming that you understand someone else's device. They are all different, the methods, tricks and tools for one won't necessarily work on another.
You understand android somewhat but judging by your posts, you don't understand the differences in devices and methods. But you will after you've been here a while.

thankyou so much for the fast responses much appreciated to take your time to explain. Okay i have a question what would be the course of detailed action to preform getting any and all missing .img's it may need. Also i know its a crazy question but would i be able to preform this in store with the displayed tablet that matches mine? How difficult is something like this, and is there any other methods at all I can try to boot past this bootloader. And now that i remember correctly from reading others this happened when I upgraded to 5.1 or 5.0 thank you everybody once again!

No, you wouldn't be able to get it from a tablet in the store, it's a rather involved process that requires connecting the device to PC, it also requires rooting the device and flashing a custom recovery, and that's all before you actually get to where you can pull the files. It'll take a couple of hours,or more to do it.

The only other option is pretty risky. You can try a firmware from another device that has the same CPU and hardware as your device, you'd have to compare specs. It would have to have the same CPU, same screen resolution, same camera(front and rear), same amount of RAM, same amount of internal storage, same accelerometers, etc.. It has to have all the same components that yours has.

SM-G955U1. XAA version. Bootloop problem, any help?

MY BAD, PLEASE MOVE THIS TO THE CORRECT SECTION. I'M REALLY SORRY.
Hello!, my mother bought this phone for her in the US and from day 0 it has been having problems. She couldn't use wifi or bluetooth for example, and sometimes it just kept restarting till it worked again, but without any connectivity functions, except mobile data.
I tried to fix this updating the phone using Samsung Smart Switch to the last build (AQL1) but now the phone is stuck on the boot screen no matter what I do.
Tried flashing with Odin, it worked, but the phone is still on boot loop. I read somewhere in this forum that you can install an older version of the bootloader to take the phone out of this hell and I did it, using the build AQK2 bootloader but no luck, same problem.
Also, the phone doesn't have USB debugging enable nor OEM unlock either. I can access both recovery and download mode though.
At this point I'm out of ideas, can someone help me with this one?
Thanks in advanced.

No I haven't, I will give a try soon through web chat.
I mean, this shouldn't be happening, it's a brand new phone, all over the internet are people with the same problems as me and looks like so far there is no solution.
Maybe it's a faulty phone/hardware? My knowledge is not enough in this matter.
See you!,

I need a couple things from you
1. What model does it say on the back of the phone i understand you posted it in the header but please for safety sake .
2. Go into download mode for me so i can see what carrier it lists
3. Try wiping data cache in recovery

Thanks for answering!, here it goes:
1. It says SM-G955U1
2. Carrier: XAA
3. Done, still the same.
An update from my last post:
After a few bootloops the FRP screen showed up, as the phone can't use wifi yet I managed to access using mobile data and enabled the USB debugging, but after trying to enable wifi the phone froze and went on bootloop again, so still the same but with the USB debugging enabled. I'm currently on the build AQK2.
Thanks again, and I hope we can fix this.
Update 2:
I cleared the cache, after a few bootloops the phone actually boots (gets to the lock screen), and it restarts again while the message "Android is starting" is loading, so now it's a different type of bootloop I guess. It does the same even in safe mode.
I will turn it off for now.

Sadly it didn't work. The phone is still loading till "android is starting" sign and then restarting again.
I will write you so you can help me through pm, could this be a faulty hardware?

I'd like to know the other solution too.

I will tell you all what todo as a last resort.
IF YOU CHOOSE TO DO THIS I TAKE NO RESPONSIBILITY IF YOUR DEVICE STOPS WORKING OR DOES NOT TURN ON!!!
Follow all previously said steps i outlined but when you go into the options tab select nand erase all also then flash device.

I don't know how many Millions of S8 / S8+ have been sold - But your post is the first that I've ever heard of anything like this... I concur with the recommendation that you call or Chat with Samsung Technical Support - Preferably before you find the phone completely unable to Boot into Download Mode - Get Samsung to help you - or you may risk voiding the warranty if Samsung determines that you are ultimately responsible for the state of the phone ??

Thanks for answering!, sorry for my late response.
Well, if you check samsung's official forum there are a few threads with 15+ pages of people complaining about wifi issues (https://us.community.samsung.com/t5/forums/v3_1/forumtopicpage/board-id/GS8QA/thread-id/862/page/1 and https://us.community.samsung.com/t5/forums/v3_1/forumtopicpage/board-id/GS8QA/thread-id/30601/page/1) about bootloop problems, (https://us.community.samsung.com/t5...id/GS8QA/thread-id/3920/highlight/true/page/1) also there is a post on another webpage talking about bootloops on this model and how to fix them (https://thedroidguy.com/2017/12/sol...p-issue-s8-turns-screen-remains-black-1079013).
I know it's not representative, as you said, millions of phones has been sold, but what I meant when I said "all over the internet" is that you can easily find people with this same problem. This shouldn't be happening, not on any phone even less on such an expensive phone.
I think the phone is officially dead, I took it to a well known local technician and even him couldn't fix it. My nearest official samsung service is 1600km away. On the other hand, my aunty got for herself an S8 and it's working perfect, so it's just bad luck for my mom I guess.
The phone had issues since she bought it (wifi and bluetooth didn't worked at all, but she is not really a tech person so she thought it was fine), the phone was working with some bootloops from time to time and after a while it fell from and got a little crack on the top but it didn't change the behavior of the phone, it was still ****ed up. That's the thing, because of the crack I'm pretty sure they won't take it back or even try to fix it (for free at least), they will say the problem is because of the fall. I'd been reading a lot about this and seems that I'm pretty screwed D:
I will sell the phone for parts. At least I will recover 60% of the initial investment.

If you have some 'proof' the problem existed, before the crack, and can prove when the crack occurred, or reasonable determinate approximation, small claims court will vindicate you, and Samsung will have to pay.
Sad to say would take a little time of yours to get them there, but it is an easy process, and with reasonable ability to determine/evidence those two things, a sure win.
But still a PITA.
