[Q] HELP!!!! note 3 bootloop

Hello everyone,
i am fairly new to the world of rooting and recently encountered a problem while flashing a rom
i have the at&t samsung galaxy note 3 N-900A running 4.3 jellybean (2 year contract expired and i got and used the unlock code)
i rooted the phone using the kingo root app, because i could not update the phone (I recently moved out of the USA so i cant connect to an at&t server to update)
i installed safestrap recovery 3.71 and it was running fine
i found a tutorial from galaxy note 3 root for the knoxraid ro
(put youtube. c o m here) /watch?v=8HDHt4xSnQY
according to the tutorial i had to install the rom over the stock rom file
so i copied the stock rom to rom slot 1
this is where i messed up, i installed the knoxraid rom over the stock rom without wiping/data factory reset first. But it gets worse, i realized i forgot to wipe the data from safestrap so before the install was even halfway completed, i pulled the battery out.
now whenever i turn it on it will go straight to recovery mode
it wont even turn off. i have to pull the battery out.
i can get to download mode and recovery mode but thats it.
im not sure about the build number because it wont boot up
all i can tell you is it is a at&t note 3 running 4.3 jellybean
please help if you can
btw: my computer wont recognize the phone because it says the PHONE does not have the correct drivers installed
however odin still recognizes it with the blue box with 0:[COM6] if that helps
so yeah please help me the phone is fairly new and i dont want to waste $600

thanks in advance

Is it possible to install a different regions firmware to my S4?

Hey guys quick question before I download and attempt it, I have an Australian i9506 (Cat 4 LTE) but we don't have an official 5.0.1 firmware yet.
Can I just download the Nordic version from http://www.sammobile.com/firmwares/database/GT-I9506/ and install it, or would it brick my phone/radios not work?
Thanks

Hi mate,
Yes you can !! it will not brick it , you may have (or not) problems with the modem as maybe is not the best for your region but you can always flash another...
should not be a problem
BACKUP first , nandroid and your EFS Folder, just in case there is a problem

Just to add to the previous suggestion, use Wanam's EFS Backup Tool rather than Samsung Tool, as it not only backs up the EFS partition but the hidden partitions where the IMEI and the modem are stored.

+1 mate!!

It also depends if your phone is carrier locked.

Thanks for the advice guys I'm giving it a try now, will edit as I go. My phone is not carrier locked (Voda AU don't lock them fortunately but they provide the codes on their website for free to unlock anyway).
So I downloaded Odin3 3.09 and the firmware I9506XXUDOA6_I9506NEEDOA6_NEE (this is the link from sammobile).
I'm following the instructions I found on another site but it's basically put the phone into download mode (home, power and volume down), agree to enter download mode, in Odin for AP select the .tar.md5, make sure Auto Reboot and F. Time Reset are ticked but not Re-Partition or anything else and start.
EDIT 1: The phone rebooted into recovery and updated something, now the phone is booting with a new boot animation. (for those referring to this I was on the latest AU Voda FW, then updated to CM12 5.0.2).
EDIT 2: After the usual nerve-wracking amount of time of first boot the boot logo finally went away and the usual "optimizing apps" message has come up and it's started (235 apps whoa the bloat). Waiting for that but at least it's working to a point where I can recover it. I just realised it's 6:10AM now and I FORGOT TO MAKE A BACK UP. I hope this works but worse case scenario there's a 4.4.2 Vodafone firmware I could flash and try my luck with if this doesn't work out.
EDIT 3: I'm not sure if it's part of the setup process but the word "UP" then a short progress bar appeared on the screen, now I've got only a black screen with a status bar (4G icon is there but no clock). I have rebooted from the power menu, let's see what's going on here.
EDIT 4: Cache wipe from stock recovery didn't work, trying factory reset from stock recovery. I note that the first time I set up the phone it was plugged into the computer with ODIN still running, I don't think it could have interfered but I unplugged the phone this time just in case.
EDIT 5: I'm not sure if it was ODIN or needing to do a factory reset but it's working now, I'm running through the set up. WiFi is working 100%.
Final EDIT: Everything is working 100%, tested the camera, proximity sensor, screen rotation, voice calls, mobile data, wifi and it's all 100%.

Thanks for let in us know.

For any other Aussies out there trying this I'm on day two and everything is working perfectly, getting root is super easy too, just use Odin to flash a custom recovery (Solk's CWM from May 2014 works great), boot into the recovery and install UPDATE-SuperSU-v2.45.zip, exit and when it asks if you want to repair root say yes. Reboot, go to the play store, update to the latest SuperSU and all is well.

[Q] Wifi lost; Unique problem maybe.

Anyways as my title says, i don't have wifi. I had first rooted my phone, but then I unrooted my phone by flashing some unrooted os on the samsung which caused two problems. My wifi and mobile data didn't work at all, but after I took it to a repair shop they fixed the mobile data and got it working again and rooted my phone but not the wifi part. According to the person that tried to fix my phone, the current android os, 4.3 - jellybean, that i flashed via odin is preventing the wifi from working. I don't really know whats wrong with the phone but can anyone help me? Also by baseband version is 1337UCUFNJ4 and the build number is JSS15.1337UCUEMK2. Should i try to find a ROM that matches my baseband version and flash it via odin? Thank you in advance!
P.S. This is my first thread, so please tell me if i violated any rules.

im having the same problem and i think we both have knox stupid security back on the phone that's blocking the wlan to start from bad permission or encryption
so personally yeah i will install back the original firmware (before 4.3) from factory reset (or via odin if i have to force it) then im gonna re-root the phone
having back permission ill remove knox (probly with titanium) lock and box bs from base firmware and probly remove root right
then im guessing ill have my internet back now will i go full rom again or basic function thats a good question
so many freaking remote exploit lately
ill let you know if that fix it

I also just found this
om22 said:
1. untick "Auto reboot" in odin
2. flash the stock rom again
3. reboot your phone to download mode again (by holding the power and vol down button for 10 sec)
4. flash the stock rom a second time with auto reboot ticked
This will fix your problem.

seems that clicking auto reboot might be the cause

so would i install the I337_NJ4_Stock_Kernel.tar.md5 file following that method or would i have to find another firmware/rom/(i don't know what to call this) unrooted

Instruction can be found on this thread : http://forum.xda-developers.com/showthread.php?t=2372286
knowing the problem was modem i did also found this solution to re-flash and fix wifi on i337 without changing to 9505
Follow these instruction to stay i337 : http://forum.xda-developers.com/showpost.php?p=46762296&postcount=1
but i have not tested for i337
in the end i got this setup

[OTA] Yoga Tablet 2 830F - Android 5.0.1 - Lollipop ota update 2

Lenovo Yoga Tablet 2 830F - Android 5.0.1 - Lollipop ota update 2 from Lenovo (20/7/15)
Filename: YT2-830F_USR_S000195_1504220230_WW21_ROW_TO_YT2-830F_USR_S100067_1507101258_WW52_ROW.zip
Size: 1,15 GB
Link: https://drive.google.com/file/d/0B1j7Qr4n1Z15U3pXMTdNdHRfd1E
INFO !!!
My first update OverTheAir with this file was a fail. Only black screen after update and reboot.
(I think because i did not change the country code after flashing KitKat a few weeks ago)
(If the update stuck at 100% in recovery you also have to reflash KitKat ROM)
So i flashed original 830F KitKat ROM via "PhoneFlashTool" with this ROM / Tutorial:
https://cloud.mail.ru/public/Z2US9gd..._150422_ROW.7z
http://www.android-hilfe.de/thema/tutorial-wie-installiere-ich-das-kommende-update-wenn-es-nicht-funktioniert-fuer-alle-varianten.697884/
Changed the "Country Code Setting" via ContactApp ####6020# to "de" (select your language).
And do not update any app like Chrome etc. when it reboots again after.
Then download and start the Lollipop 5.0.1 Update.
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS... :cyclops:
INFO 2 !!! (if you installed Lollipop update 1 first and now restoring/flashing of KitKat ROM fails)
matshias said:
I have the same problem, only that I had the first Lollipop version for 1050F with root and then got the new Lollipop update. The Kitkat version fails to flash. But here is what helped: Go to this post http://forum.xda-developers.com/thi...-8-10-13-3-t2930428/post60490907#post60490907
and download the LtoKKxml.7z and copy the files into the kitkat firmware folder and then flash using flash-LtoKK-PVT-810.xml
I had to remove the parts of the XML that erase and format data. Then it worked
After that I could flash KitKat!!

LOLLIPOP ROOT
So easy, follow steps 1-8: http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096
I download "IntelAndroid-FBRL-05-16-2015-PTR.7z" and "UPDATE-SuperSU-v2.46.zip" and it worked with Lollipop 5.0.1.
Make sure you have all the Android, Intel, ADB driver stuff installed (for me win7 installed another one at rooting?)
!!! USE OPTION T4 FOR LOLLIPOP ROOT !!!

Yup I got the notice a few mins ago. I also got it many weeks ago when it bricked my yoga 2 8.3
Advice, when it says Updating....100%. Leave it alone. Last time I thought it was done since it said 100% for many many minutes. So i thought it was stuck or bricked. Just let it sit. It will reboot by itself and restart to the next phase.
It will also sit on the Lenovo android screen for quite a while before it goes to Android is upgrading.

Yes, i got problems too!
- It stays for 8min. at 100%. I leave it alone...
- Then 4 chinese Buttons showed up.
- I pressed the first (reboot i think)
- it reboots, it shows the white lenovo text, then black screen with background light on.
- i waited 10min., no change or start into OS.
- then i pressed 15sek power off, light goes off.
- if i power on, again white lenovo text, then black screen with background light on. nothing... ???
i reboot into recovery and wiped cache, nothing.
i think i will make update from SD card again... see if something happend

Update again from SD dont work! it says:
"/system/app/Chrome.apk" has unexpected contents...
E: Error in /sideload/package.zip

SUCCESS, LOLLIPOP IS WORKING!!!
I Have restored original KitKat ROM via "PhoneFlashTool" with this ROMs / Tutorial:
https://cloud.mail.ru/public/Z2US9gd6f2ei/YT2-830F_S0195_150422_ROW.7z
http://www.android-hilfe.de/thema/t...icht-funktioniert-fuer-alle-varianten.697884/
This time i´ve made the "Country Setting" via ContactApp ####6020# to "DE" befor download and upgrade!
And i have aborted the automatic PlayStore updates for Chrome etc...
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS...

So can you boot back into android? Even after you wiped it? If not and you can't do anything, call Lenovo. I think only they can fix it.
If you can get back into android, I would suggest waiting for the System update notice. That's what showed up this morning for me. I didn't have any chinese buttons. I didn't have to touch anything, just wait for a really long time which is unnerving because I don't know status.

I flashed the KitKat Version again, changed country code, and installed the new Lollipop 5.0.1 update again.
This time there are no chinese buttons to press. (i think because changing the country code befor update).
Lollipop is great, the display is much faster while scrolling in chrome etc.

Interesting. I wonder what the difference between the versions of the country codes are. Mine bricked last time it was updated to lollipop. When I got the repair back, it was back to kitkat and I couldn't update until this morning.
Glad to hear you got it fixed. A few of my apps also stopped working and I had to clear the cache to get it working again after the update.

There are some differences in pre-installed apps. I did not changed the country code few weeks ago because there are some apps in german setup i do not want...
**** Edit *****

mine is failing on Lenovo Recovery. It will go to 100% and failed. I had to reboot. FYI, mine is rooted.

You need to flash the stock kk firmware.

Yes, It looks like I cannot just upgrade from rooted KK. I had to go back to stock kk firmware provided in the OP's link and follow step by step instructions using google translate. thanks workdowg and 5m00v3.

anyone missing 5GHz band Wi-Fi support with country code DE? I cannot seem to change the country code once it has been upgraded to Lollipop.

Lollipop does not longer provide the option to manual change band... it will auto connect to 5ghz if possible.
It has nothing to do with country code DE. You can check your connection 2,4/5ghz with the app "wifi band".
My YT2 connects automatic to my 5ghz. And i have 2 networks (2,4 + 5ghz) with same networkname.

Hi,
I have the same problem, black screen after OTA Update, but now, impossible to acces to recovery, dirrectly a black screen after "Lenovo" logo, have you an ideas ?

Okay, I found the solution ! Make the tablet totaly Off, press volume up and volume down, than press power bouton, you directly acces to fastboot mode, and here you can flash with Phone Flash Tool.

Hi,
thanks for the timming TIPs !!
I can't believe LENOVO dosen't take care of this basic things !!
Thanks to you Lollipop is running on my beloved Yoga.
A little tip while we are avaiting 5.1,
Go in Parameter
Activate DEV options : About this tablet, touch 7 times on "Build Version", it will activate the Developper Menu in parameters
Go to Developpers Option (in PArameter)
UNCheck NuPlayer in multimedia.
--> REBOOT your device
It will allow you to avoid Lagging into the UI and apps.
Note that in 5.1 NuPlayer has been replaced by a bugfree version.
Now my last issue is to root the Lenovo...
I tried the rooting method : http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096
but aleas I'm stick with an ugly : E: failed to verify whole-file signature

Tried with stock 2.46 and BETA 2.49.... same result.
Your help is kindly requested to solve this....

Googling ”E: failed to verify whole-file signature" and each one talks about a corrupt download... They are old posts from 2013 or so but they could be right.
Try this version 2.40. You can update in the Play store once your rooted.

Thanks for your help.
I tried the 2.40 version triple check the zip file, aleas same error...
Also there are not only corruptions problems related... some are related to CMW version problem and lack of "unsign" option..
Again thanks for the 2.40 link. If you have any suggestion I'm all ears.

There is a new update, to yt2-830f_usr_s100191_1511230623_ww52_row
anyone tried it already?

Looks like it requires going back to stock KitKat again just to update it.
Can't really be bothered trying it.

stuck on loading screen, can't go back to stock firmware

Good day,
i tried flashing custom rom in my Note 4 N910C. however, i messed up big time. i had many problems, then i decided to go back to the official stock firmware i have in my PC.
every time i run the ODEN, i put the Rom in the PDA, then click "start". it takes a few seconds, then i see this message (all threads completed. (succeded 0 / failed 1)
i tried restarting my PC, but no luck. i changed the PC port, but no luck. i restarted my phone many times, but no luck.
it is worth mentioning that i wiped everything using the recovery mode.
the download mode information:
Current Binary: Samsung official
System status: official
Knox Warrant VOID: 1
RP SWREV: 2
SW REV. CHECK FAIL. DEVICE:2, Binary: 1
all i want now is to return to my stock firmware and my phone is working again
i am no expert, but i want to learn, but that is why i risked it
can you help?
thanks so much

Go on SamMobile site and download the rom related to your device. Apply via Odin and ready
You can also use the Phone Info + app to get the exact ROM for your device

before i ruined my phone, it was running 6.0.1 Marshamallow.
i am now downloading Marshamllow ROM from sammobile for my note 4. and i will try again. hopefully it will work i will be really broken if it does not work again!!!!!

You can not download any ROM version. It has to be in your area. You know what is the base version of its N4?
You did wipes after you have installed? Enter recovery mode - wipe - advanced and select "Dalvik, System and Cache"

yes, i am downloading the the ROM version that is suitable to my phone which is N910C.
and yes, i did wipe everything actually.
i have been sitting on my PC for hours, but due to my lack of experience, i am having a very hard time resolving this issue.
i hope it is resolved

Okay. Take it easy
You wore what version of Android? 4.4.4? 5.1.1?

i really thank you for trying to help out bro
before i ruined it, it was running Marshamallow 6.0.1 stock firmware.
after having issues, i had to wipe everything and flash back to an older version 5.1.1 (i have it in my PC). and only then i started having these issues i stated earlier.
i am still waiting for my download to finish, i am downloading the Marshamallow 6.0.1.
i started to doubt that flashing it to an older version, maybe this where the problem is.
what do you think?

Use google translator ... lol
There is an update of 5.1.1 (a COJ5) that prevents you from coming to 4.4.4. Recently that came out a version 6.0.1 that stock also prevents returning to 5.1.1
I do not know if it can be what happened to you.
You can use the Samfirm app to be able to download faster.
When flashing is you're downloading, it gives an error post the screen here for us.

There is an update of 5.1.1 (a COJ5) that prevents you from coming to 4.4.4. Recently that came out a version 6.0.1 that stock also prevents returning to 5.1.1
I do not know if it can be what happened to you.
You can use the Samfirm app to be able to download faster.
When flashing is you're downloading, it gives an error post the screen here for us.
