Yoga Tab 2 830f Is there a soft brick fix? - Thinkpad Tablet General

I've searched but apparently it seems like most of the answers have been deleted or redacted.
My problem...
I was just given a Yoga Tab 2 from my sister who has given up on trying to fix it.
The tab was on 5.01 and rooted when she got a system update. She ran the update but now the tablet freezes during/after the boot animation.
It will go into fastboot but is not recognized by ADB.
She tried to install the original Lollipop firmware through recovery but ended up getting a system 7 error.
This is exactly what I see when in the bootloader screen
FASTBOOT MODE
PRODUCT_NAME - YT2
VARIANT - YOGA Tab1
HW_VERSION -
BOOTLOADER VERSION - unknown
IFWI VERSION - Blade_21.x64.0005.R00.1504101447 FFD8_X64_R_
SERIAL NUMBER - BaytrailD454B***
SIGNING - ?
SECURE_BOOT - ?
E: No valid installer medium found
I know nothing about Lenovo and how they do things but I know that with HTC you have to go back to 100% locked and stock before you can install an OTA. If you do try the OTA usually just won't install but unfortunately this thing seems to be at least soft bricked.
Is there a way for me to maybe roll back? I've read about people going back to KK in order to get the LP OTA but all links to the KK firmware are gone.
Thanks a lot, I appreciate any help I can get...
BTW, She is under warranty but of course she was rooted and is worried that repair will cost her almost as much as she paid for the Tab when they realize and void her warranty.

If its the same as the 1050f try these files.

Thank you. I used the Restore KitKat Bios you posted along with an 830F specific KitKat firmware from the Russian Lenove site. Worked fine after editing the flash.xml file to allow for a larger system.img file.
The tablet is now back from the dead. Unfortunately it gets the 5.0 update but fails in the Lenovo Recovery when trying to flash the OTA. It gets to 100%, stays like that for a bit and then a blue X saying flash failed. After that I'm back to a black screen and have to reflash the kitkat firmware to get up and running again.
I have no idea why the OTA flash constantly fails but I guess I have to do a bit more research and hope I can get her up to date.

Did you set the country code , without setting it updates fail.
Look at this advice from ionioni to me about setting the code

Outstanding!!! I entered the code in contacts and it gave me a menu of different countries to choose from. I Chose US and she rebooted, went into recovery, ran a bit and rebooted into another fresh install which looked completely different. We're talking different wallpaper, and different apps. After that it successfully installed 4 or 5 OTAs and as far as I can tell it is now completely up to date!
Android Version is 5.01
Build is S100250-160119
Kernel Version is 3.10.20-x86_64byt-g9f7fad7
Security patch is dated 2016-02-01
I'll wait a few days before I root and install Xposed just to be 100% certain it's up to date.
Of course my sister will probably ask for it back now.
Either way, THANK YOU VERY MUCH corasman!!! Your help has been invaluable!

I am so pleased it worked for you, ionioni helped me so much and now I am trying to do the same for others.

[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)

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...

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.

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
when trying to apply latest SuperSu when in recovery mode...
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.

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":

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

see jaunedoeuf's answers
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

Yoga Tablet 2 1050L Firmware Upgrade!

Today i receive notification about upgrade, im now donwloading it but cant find what update is it...
its not something 50mb update, its 1.37GB update.
nothing on lenovo's web pages.
maybe someone knows what will bring this update???
i cant add screenshot (( what can i do???
Let us know if you see any significant changes when it's complete.
sure, its about 60% now.
rframe said:

while i cannot say what is new (not having an 1050L tab) i did downloaded and checked inside
this is what he does:
1. writes on ESP a new x64 bootloader
2. writes a new boot image
3. writes a new fastboot image
4. updates the bios with a new capsule (and by the size it writes over all the bios region)
5. writes a completely new system image (however it does it by using the patching way, even more using the block-update)
all in all excepting your data partition (where you have your personal data/preferences and the apps you personally installed) it will do a fresh new install of everything
problems one could have:
1. obviously if you had an unlocked bootloader you will need to flash back again
2. if the bios updates also the security part it's possible that you will no longer be able to use the unlocked bootloader
3. the new system is wrote by block patch (they could have wrote by flashing method) and this means you can have problems if you modified it (ie mounted at some point and changes something on it) by rooting or something else
on the bright side now someone could build a 'stock' rom for this model using this ota (so you can flash lollipop stock rom from lenovo and even a recent one by means now known)
So is it still 5.0 and not 5.1? Seems excessive for a bug fix build.
10x, i have stock not rooted not modified.
its 99%, i will write today if android version will be changed.
its 02:22 am on my clock and i must sleep tomorrow i will check what will be changed.

ro.product.ota.model=YOGATablet2-1050L

so no, it's still 5.0
it's big but it's also lenovo , joke aside this way it's better than incremental patches and it also gives you basically a stock rom (well first someone should compile it)
Ahh right, just stagefright patches then no doubt.
Yeap, its still 5.0.1
We recommend not to upgrade if you want to change?
i didnt find something changed. but i think the overall performance is increased and it better gets wifi signal...
They fixed also the new user problem
Now u can add new user or switch to the guest mode
Is there anyone noticed anything else?
Is the bios now is x64?
Has anyone received an update for the 1050F model?
firmware update 1050L not possible
Every time I try to install this update, which comes up every day, I get the message that my SD-Card is making problems.
But even if I officially unlink the SD-Card and take it off, the error message stays the same and I can't update.
How can I solve this problem?

Recovery bricked after Nougat update?

First excuse me for opening an other thread like this, i think i have read all other threats regarding my problem, but none have the same situation
My Huawei M3 Wifi (BTV-W09) seems semi bricked after installation of Nougat Update.
The Installation (Force Install with dload) gave me an error and also while boot i got the error message: "Your device has failed verification and may not work properly."
I have the option to press "Powerbutton" and the device will boot up. I checked the Version and it showed android 7 + EMUI 5. The only problem was that almost every system app was missing, like keyboard, calendar etc. (playstore was there)
So i tried to do the rollback with:
HUAWEI MediaPad M3 8 Rollback Package%28BTV-W09 %2CC900B300%2C EMUI5.0%2BAndroid7.0 rollback to EMUI4.1%2BAndroid 6.0%29
The Installtion (force update) gets stuck at 5% and after like 3-5 minutes the tablet will boot up showing the same boot error that can be skipped with pressing powerbutton. I checked sytem and it still showed "android 7 + EMUI 5" but built : BTV-W09C900B300
I think this is the one i "need" to be able to install the "HUAWEI MediaPad M3 8 Firmware %28BTV-W09 %2CC100B006%2C EMUI4.1%2BAndroid 6.0%29"
Problem is regardless which "update.app" i try to force install will get stuck at 5% and give me same error. I have ADB/Fastboot installed and tried some different things like flashing/unbricking it with "Huawei Multitool" where you can extract like boot.img or recovery.img and try to flash it.
Also getting an error. I can access eRecovery witout problems, the option to fix it by itself by wifi doesn`t work. I can´t access "normal" recovery and i think there is the problem (may got bricked while flashing Nougat?) I think its recovery problem, cause when i boot it up to the "half-installed" Android and go into setting "hard-reset" option i know it would boot up intoi recovery and would erease everything, while bootup it shows error "reset failed".
In fastbootmode i see bootloader: unlocked FRM: unlocked
I tried to install TWRP recovery with adb but get error: adb remote command not allowed
I downloaded like 15 different Android Versions 6+7 Emui 4.1+5 to try with force update but none worked, may i have to flash special version of recovery first?
I just want a normal version of android 6 or 7 i dont mind but at the moment with half working 7 "without" systemapps its a hardtime.
I hope someone can help me.
This isnt my first android device and im not a total noob i unlocked bootloader and flashed kernels on many other phones but with the W-09 where i did nothing special i dont get why "recovery got broken"
Thanks in advance
You haven't read other threads too well: more times people reported that the bootloader got locked after an update still declaring itself unlocked!
Second thing you have not found: the Nougat update consist of 2 packages and the second must be installed from TWRP.

thanks for your anwser, i read that so i also tried unlocking it "again" and it quotet it is also unlocked in adb. I also know that there are 2 packages. That you need TWRP i didnt know thanks so i am a bit smater now. I think i ll try "relock" and unlock it again might be the right way, thanks for the tip.

I just uploaded a picture, i choose "before EMUI5" cause this is the only option i can choose "tablets". --> i choose "tablet wifi" , enter product model "BTV-W09" then the serialnumber i can see in setting: 28D6R17316XXXXXX but then i have the problem to input product id, it say i can get it through "Dialer" app (which i dont have in wifi model ) or the calculator. Problem is in my damaged installation there is no huawei calc, other calcs from store dont work (read that problem in other threats) I tried many apps from appstore to get a product ID but huawei site keeps saying wrong product ID =/
With the program DC Unlocker i am able to see a MEID i dont know if its the right one, i tried my luck with the Product ID Generator from Huawei but it doenst work. (device not supported)
It's very strange that it says bootloader unlocked if you have never unlocked...
And was very stupid to try to installl a beta release without before unlocking and taking a backup.
Exhange your device for a Nokia 3110!

yeah at this device i never touched bootloader, i didnt think it would become such a big deal , i didnt want unlocked bootloader or other recovery just newest android. Never had any problems with the "force update function" to come back to stock. I tried DC Unlocker but cant get further cause device need to get into manufature mode (thorugh dialer or calculator which i both dont have) i hope maybe i find one more way.
Did you ever find a fix
Did you ever find a way to fix this. I'm in the same situation. I even did a VPN on my router to give me a Hong Kong address for erecovery and that still didn't work. I have the exact same product. Like you I tried to various attempts to download a new recovery, but nothing works. Nice hardware, but some of the worst software/firmware I have ever dealt with since starting with the first release of Android on the HTC Hero.

I had mostly the same problem. I rolled back to 4.1 using the rollback and the actual 4.1 update.app. I think that puts you on C100 if I remember right. Tablet I have is C128 (USA) but no problem for this step. Get the Product ID from the calculator. Allow OEM unlock in the settings, then unlock it using the unlock code. Email yourself the unlock code because who knows if their website will even be functional next time. Alternatively you can extract the stock calculator from the update_data_usa.zip or whatever and try to use DC with 5.0. That second update zip does not install properly via the dload method, so a bunch of stock apps don't get installed. You can kind of hack it and flash it via TWRP but I didn't do it that way.
Or...you can use firmware finder to force an OTA from 4.1 right up to 5.0 (350), then take that last partial OTA to 351 after as well. The way to do that is via DNS in firmware finder. Find the Full OTA in firmware finder you want, send it to the updater by changing your DNS the way it tells you to, and when it does the OTA, everything will be properly installed basically the official way. Good as new. Flash TWRP to recovery2 and replace the erecovery. Keep the stock recovery as is. Install magisk. Golden.

So i tried to do the rollback with:
HUAWEI MediaPad M3 8 Rollback Package%28BTV-W09 %2CC900B300%2C EMUI5.0%2BAndroid7.0 rollback to EMUI4.1%2BAndroid 6.0%29
The Installtion (force update) gets stuck at 5% and after like 3-5 minutes the tablet will boot up showing the same boot error that can be skipped with pressing powerbutton. I checked sytem and it still showed "android 7 + EMUI 5" but built : BTV-W09C900B300
I think this is the one i "need" to be able to install the "HUAWEI MediaPad M3 8 Firmware %28BTV-W09 %2CC100B006%2C EMUI4.1%2BAndroid 6.0%29"
Problem is regardless which "update.app" i try to force install will get stuck at 5% and give me same error.

Also, as far as the rollback, you need to do the first one (the C900 which is just a compatibility fix to allow rollback, previously used by beta testers I believe). Then you need to do the second one, the C100. If it is getting stuck, try downloading it again and be sure you don't have anything else in the /dload directory on either internal or the sd card. I had one on both at one point so maybe that happened to you. The C900 should be very quick but the C100 will slowly progress after 5% all the way around in several minutes.
When you get to updating back to 5.0, you can choose whichever region you want as long as it is a full OTA. C128 is USA and that's what I bought so that's what I picked. That gets you back in the right OTA update channel after that.
Hi guys,
I started as a novice and have learnt the hard way.
Has anyone tried rollback to EMUI 4.1 EU version on a US device (W09) and are there any problems I should be aware of?
I have had the exact same problem shared in this thread and have gone through the pain of finding a solution. My last resort is to rollback to 4.1 and restart the whole process.
@deV14nt: you suggested that when updating back to EMUI 5.0, I can choose the region even if my EMUI4.1 is EU version. How does this work?
Thanks in advance for your help.

S7 SM-G930P ~ Boot Loader Issues? SW REV CHECK FAIL : [ABOOT]FUSED 5 > BINARY 4

Hi All.
Thank you for any help you might give me in advance with this issue...
Last week, I tried to root the phone with the SM-G930P CF-Autoroot heroqltespr files with Odin found in this forum. I have rooted a few other phones but am no expert. The root after a few attempts failed (verified a few ways), however, some files must have been affected because the phone "identifies" as heroqltespr. Identifies as when I could plug into my PC heroqltespr would be the name. It was not set this way in the obvious name your device areas. I ended up doing a hard reset to clear the phone and other than the ghost naming everything was working fine.
A day or 2 ago Sprint rolled out a new OTA update which the phone installed. Since then the phone was draining battery life. After uninstalling and reinstalling the SD card today, it seems to have tripped a "Security Notice: Unauthorized Actions". That is when the trouble started. The phone started running hot, basically leaking battery power, and was all lagging. I'm assuming the CPU going Ludicrous speed.
Now, I am in a Samsung Splash screen loop, or or a recovery loop. The only thing it does is go into download mode.
I have tried flashing stock firmware, it fails. I've tried flashing with and without the SD or Sim card. Not really sure what I should be doing. The "P" version of my phone seems to be the bastard child of S7s. Any help you guys cold give me would be great. THANK YOU!
The Download Screen Reads:
Odin Mode (High Speed)
Current Binary: Samsung Official
System Status: Custom
FAP Lock: Off
Warranty Void: 8x8
Qualcomm Secure Boot: Enabled
AP SWREV: 85(2,1,1,1,1) K1 S4
I get this error when I try to flash back to stock SW REV CHECK FAIL : [ABOOT]FUSED 5 > BINARY 4
Stupid question but is your phone in a case?
Sw rev check fail : [aboot]fused 5 > binary 4

No it isn't.
I get this error message on the download screen. SW REV CHECK FAIL : [ABOOT]FUSED 5 > BINARY 4
I fixed it.
5 > BINARY 4 error, has to do with a Version 5 bootloader Sprint came out with in 2018. The fact that this is only affected by the SM-G390P further complicates things for the average user. Users on version 5 bootloader will need to wait until/If a version 5 universal bootloader for the SM-G930U to get unbloated firmware. Information on restoring your S7 SM-G930P to where you left off before you started trying to root your phone can be found below. More info on Sprint F'n us and BL Version 5 can be found here
https://www.arencambre.com/blog/2018/01/01/fused-firmware-version-locks-samsung-s7/comment-page-1/. There was a post on XDA (which I can't find) which gave the idea that Sprint came out with this version 5 bootloader to prevent people from flashing the phones to the U version and going overseas with them.
The stock files for the first version of Sprint Version 5 bootloader firmware dated 1-1-18 can be found here:
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930P/SPR/download/G930PVPS5BRA1/206876/
Unzip. Only have auto reboot and Re-partition checked as options in Odin.
If you dont mind me asking, did you ever find a way to root the G930P with the 5th bootloader updates? Is it even possible at this point in time? Im new when it comes to rooting but with the amount of time Ive spent browsing the web it seems as if there is nothing. Thanks.

I got screwed by this, I accidentally installed the P firmware, and now I cannot load U firmware because of this 5 > 4 error. I went to the blog you posted (arencambre), and I am only able to install the U firmware modem (CP package in Odin), everything else has to be P. And because of the P firmware, I am unable to edit APN settings to enable my native Hotspot. Is there anything I can do, besides wait for U firmware to come out with a Version 5 bootloader?

Actually, I am on Sprint, and your directions were awesome, thank you so much! The only thing I had to do was change the line to:
settings put global tether_dun_apn "APNDUN,n.ispsn,,,,,,http://mms.sprintpcs.com,68.28.31.7,80,310,120,,default,dun,mms,supl"
I'm going to put a link to the thread so others can refer to it. https://forum.xda-developers.com/sprint-s7-edge/how-to/hotspot-bypass-nougat-ok-t3563446
Hi all,
EDIT: I posted this in another thread that was about two years old, where I followed the instructions that caused this: https://forum.xda-developers.com/sp...msung-galaxy-s7-sm-g930p-root-xposed-t3503599
That thread seems dead-ish and if you managed to fix this issue maybe you can help me also. Also what was lvpre's original post before he edited it, and would it apply here?
So the worst has happened - got a new (used) phone from Boost Mobile, tried this guide, and now I can only boot to the "An error has occured while updating the device software. Use the Emergency Recovery function in the Smart Switch PC software." screen. Sometimes it does take me to the original "Download mode" screen.
Now, I should be able to resolve this by flashing the original firmware correct? (As in, the firmware that was installed when it came)? Or does it just need to be firmware from the same date range that has the same bootloader? ODIN will still let me attempt flashing on this screen, but I still get the same error when I try again, which on the Download mode screen showed "SW REV CHECK FAIL : [system]Fused 4 > Binary 1"
Any advice here? My S6 bricked when somehow OEM unlock enabled itself and I can't get around the FRP lock, I will be VERY annoyed if the same thing happens with a NEW phone. If I can't fix this I am never buying Samsung again. Any advice on this is very welcome! I emailed Boost to ask them which firmware is installed (because I'm an idiot and didn't write it down but have never had flashing go this wrong before).
EDIT: Booting to recovery just shows a blue "RECOVERY BOOTING...." for a second in the corner and gives a recovery bootloop, just keeps flashing that.
EDIT: I apparently tried to flash an earlier bootloader/etc through ODIN according to the directions in the post I linked above, and after that I now have this problem. Nobody else in the thread seems to have had this problem, and your post is the closest to anything I can find on this issue. I would be in your eternal debt if you could help me out here.
PLEASE HELP!
EDIT: Theoretically if I can find the original firmware it was on I should be fine, right? Everywhere I read if flashing goes wrong you just flash the original stock on it. I guess worst case scenario I download gigs upon gigs of firmwares for Sprint 930P over the last year and find the one that sticks? Or is the fact my recovery is bootlooping and I can only go into download mode mean I'm bricked?
Hello all,
To follow up on my last post, I found success restoring to stock via this firmware:
G930PVPU4BQH1_G930PSPT4BQH1_SPR_7.0.zip
https://www.androidfilehost.com/?fid=817550096634799807
I left my original post just in case anyone messes this up the way I did. I still need root, but now I know how to reset to stock in the event this happens again.
For the record I bought a used Samsung Galaxy S7 off the Boost website.
IF YOU FOLLOW THIS GUIDE, OR ANY, MAKE SURE TO GO INTO "SETTINGS -> ABOUT PHONE" AND MARK DOWN WHAT FIRMWARE THE PHONE IS CURRENTLY ON AS STOCK. THIS WILL SAVE YOU A HEADACHE TRYING TO FIGURE OUT WHICH FIRMWARE YOU NEED TO DOWNLOAD IF THINGS GO WRONG. DO NOT PAY FOR A FIRMWARE DOWNLOAD OR USE FILESHARE SITES, GO HERE: https://simunlockremote.com/galaxy-s-series-firmware/ AND FIND THE VERSION YOU ARE ON AND IT WILL DIRECT YOU TO A FAST GOOGLE DRIVE LINK.
Thanks to all the hard work all the devs have done that have gotten use. I still need root soooooooooo if anyone knows how to do that let me know!
CHEERS! I am so happy right now

Don't take any updates. My edited post was on how to get hotspot working. There is a thread here about it, but I changed a line of code.
Switched from Sprint to T-Mobile. Am I out of luck?

I've got a Galaxy S7 G930P from Sprint. I just switched to T-Mobile a couple months ago and brought my S7 phone with me. I was hoping to flash my rom to either the G930U or the G930T (T-Mobile) version, but both are still bootloader v4 and I hit the same error that everyone else on this thread was hitting.
My main problem is that my S7 phone can't send/receive MMS messages on T-Mobile, even after updating the APN settings, and, even worse for me personally - my phone gets below average reception everywhere I go, presumably because my Sprint G930P rom has locked down some of the bands that T-Mobile uses.
Aside from getting a new phone, do I have any options? Or am I stuck waiting for either a G930T or a G930U update based on bootloader 5?

If your phone is uicc [sim] unlocked from sprint... you can try the following.
1. Odin a dec/Jan firmware...like QJ3. But replace the cp slot with the file from the latest u firmware. This is the modem file.
2. When your phone starts, you will receive a pop up message, just hit cancel.
3. Install a package disabler like sabs, bk, adhell2. Disable securitylogagent . This should remove the annoying message. Sabs takes a little effort to setup, but you may need it for the disabler part. Restart after disabling.
4. Pop in sim. See if the additional bands are unlocked.
If you fail, you can always just odin back to a v5 sprint firmware. But don't try it unless you are stuck on the current firmware and your phone is doing nothing. It won't brick your phone.
While the firmware is not downloadable, modem files can downgrade one major update.
This worked for me, but I only have sprint and haven't tried it elsewhere.
Here is an article https://www.arencambre.com/blog/2018/01/01/fused-firmware-version-locks-samsung-s7/comment-page-1/
Is this triggers the knox counter ?
