Need Help - Reverting to Stock to Sell Phone - LeEco Le Pro3 Questions & Answers

Hi All,
I've previously had Omni-Rom installed, but wanted to return to stock to sell the phone.
I downloaded a stock rom, from this XDA thread, and have installed..
https://forum.xda-developers.com/le-pro3/development/eui-5-9-23s-stock-launcher-eui-6-0-t3617371
The phone boots up into EUI, but I can't get through the setup wizard - after inputting wifi details I get an error:
"We've detected that this device is already bound with the following account: 185***#! etc.
There doesn't seem to be any way to get past this.
I'm now in a situation, where I have the factory recovery, and have no idea where to go from here.
Appreciate any help!
Thanks!

Try this method!

Weird no IMEI & baseband unknown issue + sim card not recognised

Hi to all
I hope one or more of the very knowledgeable people out there can help me. Have a qualcomm SM-N9005 32gb European SIM model which was in a constant boot loop. Ocassionally, it would get to the the set-up screen but always go back into its loop boot once a few key presses had been made. It was on one of the 4.3 roms at the time - don't know which one.
So I put in it into download mode, flashed the stock 4.4.2 N9005XXUENB7_N9005OXAENB1_BTU rom via odin and this has solved (most of) the boot loop issues.
However, the phone is now showing as having:-
no IMEI
no baseband
no sim (despite there being a working sim in there).
If I go back into download mode, it seems an additional line has been added to the several that show at the top after flashing the stock Kitkat rom - this is "UDC START".
I don't have an EFS backup so can't restore that to get the IMEI/baseband back.
I am at a loss. I have tried a hard/factory reset - no joy. I know this kind of problem has been reported in the past and I have looked at many threads but no-one seems to have exactly the same problem and not many successful outcomes.
Can someone please give me a 'dummies walk through' of what to do - my phone expertise isn't the best, as you can see!
Many many thanks to anyone and everyone who can help.
Cheers :good:

[Q] Quick Question If Someone Has a Moment, Please

I just swapped from my Amaze 4g, to a used Note 3, and I'm a little lost as far as where I should start.
It says that it's on 4.4.2, and that I cannot update due to a modified system.
Basically, I would like to get updated to 5.1.1 (or as close as is official for the Note 3), and root it.
I'm afraid I'm not familiar with Samsung devices, and because I purchased this from ebay, I don't know how to tell the exact state that the former user put it in (I expected they would return it to stock prior to selling).
It's currently a T-Mobile branded, SM-N900T, on 4.4.2, build is KOT49H, security software MDF v1.0 release 2. Kernel is 3.4.0-660648.
It is supposedly unlocked for carriers, though I have not attempted a SIM card use yet, until I can tell that what I have is a valid device and the IMEI is checked out.
Any thoughts on how to validate the IMEI, and sort out how to get my new phone up to date would be appreciated. As I stated, I expected the vendor would have returned it to stock, but that is clearly not the case, so I don't want to accidentally boot loop it by doing something I shouldn't. I have not owned a Samsung before, so I want to be careful on how it differs from my Nexus 7, Amaze 4g, and Droid X, as they're all obviously very different in the OS area.
Thank you for the help1
Download tbe stock 4.4.2 rom and use odin to install. Then you will get the OTA updates.
Sent from my SM-N900P using Tapatalk
There is no stock 5.1.1 for note 3, only cm12.1/ aosp. Latest is 5.0 and you can use odin to flash. Maybe it's rooted that's why you can't update.

Some apps to install from Play Store...
Phone INFO Samsung - this will tell you all about your phone and the firmware etc.
Root Checker Basic - tells you if you are rooted or not.
SuperSU - this is so valuable you should buy the Pro licence. Chainfire does some great work for our phones.
TWRP - I have the zip version on my extSDCard and an Odin version on PC in case I have to rebuild from a Stock firmware. CWN works OK but most ROM builds seem to be for TWRP I think and a backup from one will not work on the other.
I don't know your previous phone so you probably need Odin v3.09 - this sits on PC and lets you flash firmware to the phone. (connected by USB)
For which you need Samsung USB drivers so the PC will recognise the phone. Install on PC before connecting phone.
Then do some browsing and find the processes to root your phone and install the ROM you want. If you just want Stock and access to all your phone, you can root it after flashing the original v5.0 download (from Sammobile or similar site - note on Sammobile you need a free account to DL) and then install Custom recovery (if wanted - it WILL trip the Knox flag but that may not matter given it's 2nd hand and might already be tripped anyway)
Read, make SURE you understand what is being said BEFORE you do anything - ask if you don't.
Good luck...
N9005 Lollipop brick
Hi All, just need a huge help here, a friend of mine has been using a N9005 which was auto restarting, she went online and downloaded this firmware...N900AUCUEOC1_N900AATTEOC1_N900AUCUEOC1_HOME.tar.md5....2.5GB in size...and flashed it, but the phone is stuck in boot loop even after recovery wiping data and cache, the phone can boot into download mode but re flashing the firmware always fails.....is there a solution for this.....please help
Thank you all for the info, especially the detailed info from Journyman16. I checked, and it is flagged as custom, which is fine, so I'm going to go ahead and try to return to mostly stock, update it, and root it.
Ok, everything went well. I had to do two attempts at rooting, but I think it's just one of those things where sometimes it doesn't restart into the process every time.
All seems good. I'm on 5.0, rooted, busyboxed, and smooth sailing.
Thank you all, again, for the tips. The Note 3 is running very well. Thank you to all of the devs that have made this process so refined. I've donated to you before, and did so again today. It's outstanding to have such well versed coders, on XDA, helping out the community.

Jiayu S3 PIN Locked by Kinguser app

First of all, I may be posting this in the wrong section. But I desperately need your help on this.
I got a Jiayu S3, and couldn't not try to flash a custom rom on it, so I tried with "Pure AOSP V1 TF".
All went well, untill i found this app which was included with the rom, "Kinguser" (should be Superuser, i believe), which game me the option to toggle root.
At first and only time I opened this Kinguser app, option root was active. I did deactivate it, and reactivated immediately after.
As soon as i reactivated root, the privacy pin screen showed up.
I didn't set any PIN on my phone, so at first i thought it could be something like 1111 or 0000. Tried 5 times and it made me wait 30 seconds. Then tried another 3-4 times.
Here began the real mess: "forgot pin" (or psw) didn't show up, but at the time i didn't even know about that recovery option.
I didn't know what to do, so I just thought that a factory reset would certainly solve the problem, how couldn't it? Well, wiped everything, but PIN lock screen didn't go away.
So, wiping everything, I also deleted my gmail account from the phone, and I lost the possibility to lock phone and give it a new password (Android Device Manager). Too bad at the time I didn't know about this recovery option as well...
Now I'm out of ideas. I think I've tried every method I could find with a search of "Smartphone PIN locked". Tried with resets, plugins, deleting files with adb..
How do I unlock my phone?
little update: after a factory reset, for 2-3 seconds, it shows the default initial screen, but it doesn't last more that and i just can't do anything.
Now i managed to bring back the stock rom, but with that i lost the twrp recovery, and i can't find a way to make pc recognize the phone to reflash it.
It seems it's going worse instead of better...
I had just bought this Jiayu S3 and planned to bring it on holidays on wednesday, but i'm starting to think i won't be able to fix it before then
Did you have any resolution to this problem. I am currently sitting in the exact same boat. Did the factory reset, pass code screen still there, I didn't set a pass code. Basically hands tied, can't update firmware, guessing i'll have to get a new phone, but hoping maybe you found a miracle cure! ha! - Thanks for any guidance. - Arden (Seattle, WA)
Just flash another rom (stock/original) and start over.
How have you done that?
Can you help please?
I tried factory reset (volume plus+ power button), hard reset (volume- plus power button), update, and nothing works; I also went to two different specialized stores and they failed to find a way to reinstall the original Android version or a recent one.
Comparing the files with the factory version installed in the phone, the phone report identified three changes:
- a new file: /system/priv-app/7mK0T6e8Z5.apk
- the lost of a file: /system/app/com.android.fallen.apk
- and a modified file: /system/bin/debuggerd

To flash firmware you can use SP Flash Tool on a windows or linux computer (not sure about macosx). You have to decide which firmware you want (which one do you have now?). The 'official' firmwares can be found on needrom. SP Flash Tool can be found there as well. There are 2 popular LP firmwares built by Jiayu resellers in Europe (Xtreme from Spain and Jiayu.de from Germany). Guides on how to flash are often present at the place where you find the firmware.

I found "Xtreme from Spain":
needrom.com/download/rom-xtreme-rom-tf/
I found the "SP Flash Tool":
needrom.com/download/sp-flash-tool-v5-1424-00/
but it is for Linux... can you send me the link of the windows version?
And I could not found the "Jiayu.de from Germany": can you send the link?
Also, can you recommend some good manual for dummies?
Thanks again for your patient and help!
latest sp flash tools is 5.1532
search needrom with "5.1532" will leed you to the download page
no link allowed here, so ...
for beta 10 from jiyau.de, search google with "jiyau.de Lollipop 5.1.1 - Beta 10 (14.10.2015)".
it will leeds you to the rom.
Good hunting

I would like to add: if you come from KK and go to LP, you must use firmware upgrade to update/adjust internal SD partition layout. Good Luck! if you succeed, and are happy with firmware, consider voting @ http://forum.xda-developers.com/android/general/firmware-jiayu-s3-t3212184 (almost 100 votes)
First, thank you for your great help!
With your suggestions, I managed to install Lolipop in my Jiayu S3S (upgraded from Kit Kat) - Xtreme ROM TF (JiayuS3-5.1Extreme1.1SP.zip).
However the problem remain... the phone still is asking for a PIN (that I never had put there, in first place)...
What should I do now?
you could try factory reset and are you sure its the phone asking for pin and not the sim card

At&t LG G-Vista D631 Looping Trouble

I don't know where else to put this since this phone does not have its own forum here.
Here is my problem...
My vista was rooted and I was going to sell it to a friend so I was doing a factory reset with the phones built-in option... And the stock factory reset makes it all the way to where I enter my first and last name and then after doing so I get this error...
LGsetupWizard has stopped (there are more words but this sums it up)
And then the Setup Wizard restarts.
I then go through the setup process again thinking it will go through this time... Same error message... LGsetupWizard has stopped, and it restarts itself.
I have searched for a fix for this EVERYWHERE and cannot find a fix... I cannot even find the stock rom/firmware for my device: AT&T LG G Vista D631
The official website has no download and the only "stock" ROM/firmware I can find is for the Verizon VS880 and it's counter parts...
Can ANYONE help me get this phone fixed and make it all the way through the LGsetupWizard without it looping/stopping/crashing???
Really need some help from the pros as I have exhausted all my tools/methods in finding a fix/solution.
EDIT: I am able to get into the settings menu (with fast fingers) right after I click OK to get rid of the error message.
I have turned on DEV MOD and enabled all the settings needed in order to flash stuff and put stuff onto the phone via computer USB...
How can I fix this problem if I am able to have access to DEV MOD on phone???
Problem solved.
I used LG D631 TOT DLL.rar and LG Flash Tool.
I forgot where I got these files from, but I am sure a simple search on a search engine will help you find them.
After I got it to boot back up, I used TitaniumBackup and found that LGSetupWizard was "frozen"... So I unfroze it and did the factory reset again and it went all the way through the LG Setup.

Device not starting/black screen after stock-ROM flash via Odin

Hello, everyone,
I tried to install LineageOS on my S10 Plus yesterday. That worked so far, but I found that it didn't have a decent camera app and the Samsung Watch wasn't that easy to connect either. So I thought I'd just go back to the Stock ROM again. I then downloaded the latest stock firmware according to this guide and installed it with Odin. The installation also runs through, after the installation the mobile phone starts and after the start screen there is an Android man with the signature "Erasing". After a few seconds, the device turns off and stays black. Even if I put it on the charger or try to restart it, nothing happens. I keep getting into download mode and recovery, but that's about it. Multiple reinstallations and resets via the recovery didn't help - the phone just won't start.
I used the CSC_... and not the HOME_CSC_... at the firmware is the right one for my phone.
Is there any way I can salvage the device? I'm afraid that something in the memory is defective now, which has nothing to do with the flashing itself. Do you have any ideas?
Many thanks!

I'm glad it worked.
I was very afraid that the phone died, what did you do for 5 days in this state?
Now I have a question in my mind: When Samsung releases an update in the future, will the bootloader and modem files be updated when we update it with odin? won't it be updated? After that, do we will always update manually as twrp? do you have any idea?
Well, I simply didn't use a mobile phone in these days. It was a very "interesting" experience, but not a huge problem. I sometimes opened WhatsApp as Windows App (interestingly, which works without phone).
I don't know, what happens at a Samsung Update, but until Android 13, I will not update (so probatly never). In our German forum (www.android-hilfe.de), a pre rooted and debloated "Stock"-Firmware is provided, but I can't install it, since my Bootloader is too new (V15 instead V14 for the ROM). When it is possible, I will install this firmware. If you are interested, here is the link: https://www.android-hilfe.de/forum/...3-2022-stock-rom-v2-0-pre-rooted.1000713.html
