[Q] Problem after flashing CF-Auto Root S5 SMG900F

Hi guys im a bit rusty again in all this since i rooted my S3 and HTC desire years ago ,
I have an Galaxy S5 SM-G900F (bought seperately without any provider)(EU)
after 2-3 months now and getting the official android 5.0 upgrade, i thought it be time to Root my device again ,
i followed this link and how to from ChainFire "http://forum.xda-developers.com/showthread.php?t=2696537"
wich i been using on my Galaxy Tab 7 Lite(T110) as well and worked flawlessly
I followed the exact steps as usual , rooting went fine, phone rebooted as it should , i updated SUPERSU and its binaries and installed Ericson's Busybox,. ,and everything worked as it should ,
then i put off my phone and boot in to recovery mode to flash the Philz_touch_6.26.1-klte.zip (touch recovery)
when im in my stock recovery i facepalm'd myself because i hadnt put the flashable recovery file on my internal storage yet ,
so i wanted to reboot back in the phone so i could put the file on my internal storage so id be able to flash it from stock recovery ,,..
this is where it all got strange,.
My phone stays black after Boot logo, gives me errors like ,. SYSTEM UI STOPPED ,. and so on for about everything that keep the phone running , i mean really everything STOPS , after about 15 minutes and klicking away all the Stopped msg's , it just reboots again to do the same.
i tried starting the phone in SAFE MODE ,. . Same thing,...

Did you use the latest version of ODIN to flash the CF Root?
Think Odin3 v3.10.6 is the latest current version
If you used an old version, try flashing it again using the new one, other than that, I can only suggest trying to fix permissions in recovery if it has that option, TWRP should have it, and finally a factory reset, which is not ideal

i used Odin3-v3.07
but after flashing the root everything worked installed superSU and updated it and its binaries and installed busybox,.
it all stopped working after i went into Stock Recovery and back
id prefer not to do a factory reset Wipe,. unless i really have to to fix it ,.
im going to try reflash with the latest version then,.
i have swapped SD card to galaxy tab to put the Flashable touch recovery on the SD card, and swapped back to the phone so i could Flash the Recovery when im in stock ,.
but ill try flashing Root with latest Odin first.. thank you

the new odin is a bit less informative (to me as beginner)
i managed to use AP to flash the root again
all goes fine , it reboots
and its now upgrading android as it says and opening app's
then Black screen again,. i klick a button,. and it shows me again all the STOPPED msg's of all internal apps that are crashing,. litterally all apps,
what can i do ?

If clearing cache didn't work, fixing permissions in recovery didn't work, only thing left I can think of is factory reset

i cant fix persmission in stock recovery and flashing the philz touch recovery didnt work something about not verify signature,.
al i can do i guess is wipe data factory reset ,.but im affraid it wont fix anything

Try TWRP recovery instead
http://teamw.in/project/twrp2/229
No reason a factory reset won't fix things, worst comes to worst, flash the whole ROM again from ODIN, that will fix everything as it wipes and reinstalls the lot
Grab a stock ROM from sammobile

Thank you for all your replys mate..
I managed to get it working again by doing a factory reset in stock recovery after I flashed root with latest odin
Even tho it was my last resort there was nothing else I guess .
I'm not sure tho if this will happen again when I go back to recovery like I did when this all happend the first time while I actually want to flash a more advanced recovery then stock recovery ..
But I'll take my chances and just leave it as it is
Again thank you for your help and suggestions .

Pleased you got it working again, I would say if you think you might want to flash another advanced recovery in the future, it might be best to do that now since you have already factory reset the phone, that way if this happens again, you don't lose months of data and settings and files that you have gathered between now and whenever you decide to flash recovery

i have actually ,. i installed the TWRP u mentioned,. by taking there app from the Playstore,. and flashed the new recovery, within android and without rebooting (just in case)
im used to the old CWM thats why i first wanted the Touch recovery as its based on it,
but always open for trying new things
Thank you

Good stuff
Id say the whole entering recovery / apps crashing thing was a problem with the ODIN version you used to root, too old for Lollipop is my guess, so I wouldn't worry about entering recovery again.

A6000 rom and Gapps problems

Hey folks I'm new here and I recently rooted my phone and flashed a z5 rom from the XDA rom thread. Link below
http://forum.xda-developers.com/len.../rom-xperia-z5-rom-lenovo-a6000-plus-t3393251
And flashed this nano pack of this gapps Link below
http://forum.xda-developers.com/android/software/tk-gapps-t3116347
So it all went fine but now I'm incurring some problems.
Firstly I didn't notice that the Gapps is closed for updates I don't know if that affected the issue but the Google play is not working and some other Google stuff as well.
And I thought I'll flash new Gapps which are being kept up to date but my phone won't connect with the PC with the usb now so I don't know how do I flash the Gapps now.
I have re Rooted my phone using the Kingo app but it still won't reconnect.
So any help on these issues would be really helpful!
One last question that if I do find a way to flash the Gapps will I have to reflash the rom again?
Thanks

First dowload the gapps from opengapps.org. Go here choose ARM>>5.1.1>>nano/pico.
Then, boot into recovery, wipe system, data, cache, dalvik and then flash the ROM again and the gapps. All done...!!!

That's the prob right. I cant reach the custom bootloader I don't know why. Do you think its because of the new rom ill have to use some different recovery? I am usin twrp right now and even I used it to flash this rom. Please help

""usin twrp right now"" -- can you boot into it..??
You press vol up + vol down along with power key and release the power key once the lenovo logo shows up, to boot into twrp

no cant boot into it.
I go into the fast boot mode enter recovery commands in the command window. Then try to boot into recovery but it doesn't go into recovery. The Lenovo screen stays there or it boots straight into the phone
This method worked before like I used this way to flash the rom but now its not working.
Any help?

Brother, you have made it really confusing for me. Earlier you said that you can't boot into bootloader, but now you can boot into fastboot..!!
Also, your phone, instead going to recovery, boots directly to system. That means your phone is in working condition(Is it..?), which you didn't told me earlier.
So, if you can boot into system (normal boot). Download Rashr from play store (or from any other source) and flash this TWRP 3.0.2. (First extract this zip and then choose recovery from storage option in Rashr to flash).

Need Help; My LG G6 (H870) keeps booting in TWRP and I can't install stock ROM

Hi,
I unlocked the bootloader of my H870, installed TWRP 3.1.1.0 and SUPERSU. Everything was working great untill I decided to restore my system defaults to make a fresh start with my G6. After choosing the option to restore system defaults, my phone rebooted and it booted into TWRP. I rebooted my phone and it kept doing this all the time.
I decided to look for a stock ROM and flash that ROM.
I succesfully flashed the "LG-H87010f-Flashable.COMPLETE.zip" ROM (from autoprime's post) trough TWRP. But this did not work. I even wiped all the data from my phone (even system) and flashed the ROM again; still nothing.
Before having this issue, I had the same Baseband version, Kernel version, Build number. Only the dates and the Software Version are different.
I had the V10b-EUR-XX Software Version installed on my phone. I see this is the 10f version. I guess this should not be a problem right?
After this I took these steps solve this issue:
1. Downloaded new LG Mobile Drivers (LGMobileDriver_WHQL_Ver_4.2.0)
2. Downloaded and installed LGUP. LGUP doesnt recognize my phone as a LG G6 and this method did not work for that reason.
Fastboot mode is working on my phone; I can reboot my phone trough the commandline on my PC and things like that . However, my PC is not recognizing my phone as a LG G6 device in Fastboot mode.
My PC recognices my phone as a H870 when in TWRP. In Fastboot mode it recognices my phone as Android Device.
3. Installed LG Bridge for more drivers; did not work either
4. Downloaded Uppercut, but it doenst work without LGUP.
4. Looked all over the internet to find a Stock ROM in .zip or .img format; found nothing
5. Downloaded WindowsLGFirmwareExtract-1.2.6.1 and tried to extract the H87010d_00_OPEN_EU_OP_0327.kdz file. I extracted it into .bin files, but they were not usable. After that, I combined these .bin files into a system.img file. But that .img file was bigger then 5 GB and for that reason it was not usable to flash trough Fastboot or TWRP.
7. Looked for other methods to obtain a H870 Stock Rom, including another extraction method, but I cant figure out how to do this.
I have spend countless hours on this problem, but I cant find an usable H870 stock rom to flash my phone with.
Is there someone that can help me out with this problem? Im willing to donate some € if someone helps me to get my phone working again.
Really hoping for a kind person to help me out and provide me solution for this issue.
Thanks in advance

Try formating data in TWRP(not factory reset) then flash the 10f complete zip. Trying to perform a factory reset from within Android could have possibly messed up your data (due to TWRP being installed instead of stock recovery) so a full data format is needed.
Lgup most likely doesn't detect the phone because you wiped system. But flashing the complete zip should have restored system.
In the future make backups in TWRP to restore later.. or flash a kdz with lg bridge or lgup without wiping system first.

Thanks for your reply. I have already formatted data in TWRP, but im still having this problem . It seems like something is preventing my device from starting up. I have flashed several ROMS on other devices, but never experienced something like this. Is there something else I can try? Can I flash the stock recovery and flash the stock ROM? I got the feeling TWRP is causing this issue.
If its possible to flash stock recovery, where can I find it?

Flash the complete zip then boot into download mode and flash kdz. Lgup should see the device as a g6 now instead of unknown device. If lgup isn't seeing any device at all (including unknown device) then your setup is off.. missing drivers or something. If that doesn't work.. idk.

Don't factory reset using the in phone option. You can only do this through twrp's option. To fix this you'll need to boot through the hard side, using power and volume down until the lg logo appears then release power for 1 sec and then repress keeping volume down pressed. Confirm yes twice on the white screens to get to twrp. Once in twrp then reset again and reflash the system. Then using twrps img installer flash your twrp img(make sure it is on ext sd) again. Then reboot.

Ohhh F*** YEAHH!!! :victory: Booting the "hard side" fixed the problem!! It was the first thing I tried this morning. I just booted this way and rebooted my phone without resetting or flashing anything. Im so damn happy lol. I still dont understand what happened and why my device was actling like this. But I learned a hard lesson; backup, backup and once again: BACKUP. And dont Factory reset in Android!

Probably because you already did all the flashing prior to. Glad it worked. This happened when I first got my V20 and was stoned not thinking. I reset using the in phone option and it caused twrp bootloop. I too learned the hard way.

Had the same issue, fixed it, thanks.

My phone kept doing this booting into recovery no mattery what ROM I installed.
I got into twrp by holding volume down and selecting yes on next 2 white screens....but now this message appears all the time.
please can someone help??

Great tip @Swizzle82! It allowed me to restore my LG G6 after bootloop. It had not been detected by PC, and this hardware reset helped!

Hi, all
If I understand, and to sum up :
I rooted my LG-G6 few weeks ago, and intall TWRP. When OTA wants to install official update, the reboot stops in TWRP mod, so ... failed :-/
Is the solution to flash through Uppercut/LGUP with a .kdz file, without risk of brick the phone ?
Thx

[SOLVED] Did I just soft brick my phone?

I just rebooted my phone into recovery mode using this quick reboot pro app, it worked fine, I just wanted to test out the app so I wanted to reboot. I pressed the reboot button in TWRP, I pressed system, I saw the boot logo, but it didn't boot and it just entered the TWRP. I tried to reboot again, the same thing happened. I'm basically stuck in the recovery. I didn't try wiping data and cache or anything like that, I don't want to mess up my phone more. Can someone help me out here, I don't know what to do to fix it

Hello there, i had the sane problem one Day, never use an App tha reboots into recovery or bootloader, it Will be stock. For the fix, You have to flash the official Samsung firmware 5.1.1 or 6.0.1 via odin And your Phone Will be Just fine.

Or just reflash twrp with odin. This will reset the reboot flag.
As said use the button combo to boot to recovery and you won't have an issue.

I used partition dl mode to flash the stock oreo rom over 7.0 to keep the root. Then i flashed custom kernal for stock 8.0 but it didnt work. I have done the same procedure before and it has worked like a charm. But it keeps on giving the encrytion error when i try it now

Odd. If I had to guess anything, it would be that not all the partitions were flashed when going from Nougat to Oreo.
I once flash a Nougat ROM from an Oreo ROM and I had the same encryption issue and lost everything.
That was the last time I would trust myself again and not do a backup.

Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track...

I tried that as well. With stock recovery is says data is corrupted and doesn't do anything. I think it might be a problem with patched lg up because when i use normal lg up to flash oreo it works. But I cant root then.

I would try changing to 3.2.3-4 TWRP and then trying the procedure again. It seems that the 3.3.0 TWRP does not decrypt properly sometimes.

In the same boat as OP

Hi
Looking for a way to keep TWRP and root ... any help appreciated
I've got a US996 with the same issue as the op. I have the latest TWRP 3.3.1-0. The phone was working fine until I upgraded twrp but I might have done a mistake resetting phone outside of twrp.
I can still get back into twrp but I haven't been able to install zip files without getting that decryption unsuccessful message when booting to system.
When getting back into TWRP using hardware buttons sometimes there is a prompt asking "keep system read only?" which I never chose and swipe to allow modification. I think this happens after
I pull the battery after getting the decryption unsuccessful message. There is a reset system that I could chose under the decryption unsuccessful message but I'm assuming that will make me lose twrp
...but if my phone is a us996 and is still
unlocked, would it matter if I did select it? Wouldn't I be able to reinstall twrp using adb again on a computer after Oreo is reinstalled?
To do Prowler_gr's suggestion which guide do I follow (sounds like I should do the second option)
"Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track... "
1-[GUIDE][UNBRICK] Patch LGUP to unlock features & unbrick V20 (Variant mismatch fix) to use lgup
or this guide

Thank you for any guidance on this...

Don't blame me if this goes wrong but I'm pretty much 100% certain that you mush press the rest button. This has happened to me a few times I'm sure. You won't loose twrp. Whatever resetting goes on in the background I don't think it's an actual Factory Reset.
Edit: Just to be clear you taking about a white screen with I think in dark blue or black text ENCRYPTION UNSUCCESSFUL and something like "reset phone" option directly under it, on the upper half of the screen?

Hi ezzony
Yes you are thinking of the right decryption unsuccessful page. I get it when booting to system
after installing Oreo and magisk 19 and having wiped everything (format data too). I will get the exact wording of it tonight
Thanks!
