TWRP SM-A530F - Samsung Galaxy A8 (2018) Questions & Answers

Hello I have a small problem with my Samsung Galaxy A8 (2018) 1 year ago I installed TWRP on my phone to be able to install a custom ROM by then everything was working fine, 2 months after installing TWRP and the ROM the phone was starting to have some problems so I decided to delete it and reinstall the official rom. So here we are now to today, I wanted to reinstall TWRP except that every time I flash my phone with ODIN it puts me FAIL in red yet the bootloader and usb debugging are unlocked. I thank in advance to the people who will help me.

[Q] Samsung galaxy ace 2 GT-i8160 CWM problem

Hello, I have problem with CWM, i have rooted Galaxy Ace 2, then i wanted to update recovery to CWM 6.0.4.5. but my Odin Failed in conection. I decided to unplug phone and then i realised that i see only statement "Firmware upgrade encountered an issue. Please select recovery mode in kies & try again" (I could go only in Download mode). After long time i found a bit older CWM, 5.x.x it worked but it doesnt support kitkat. I wanted to update it from SDcard to 6.0.4.5, it has beed installed successful but when i reboot it again to recovery it was still same old version.
I have done the same things with my galaxy mini 2 in the same way and i didnt have any problem with it (kitkat works there propely).
Could you help me to fix it? what should i do, i heard that i should install JB via Odin then root again and update CWM but im not sure about it.
Thanks Athery

[Q] Lenovo S650 on a bootloop

Hi guys, my cousin bought a Lenovo S650 powered by a MediaTek SoC but it came in chinese. I went on and flashed the Rest of the World ROM (official stock) which worked fine for a day. I gave the device back to him, he went on installing his apps from the store but a day later he rang me and told me that the device was on a bootloop (which in fact it is).
I already tried to flash the stock ROM again but no success - it keeps on a bootloop.
So, I come here asking you guys what can I do? The phone had a ROM with TWRP before, so I did a full backup, but I can't even access the recovery (stock or custom, 'cause it reboot over and over), but I need to flash TWRP to restore the ROM.
Any solutions?
Thanks guys

[ROOTED] METRO PCS. Galaxy s5 on android lollipop 5.1.1

Just want to share an experience i went thru while trying to root my metro pcs galaxy s5 on android 5.1.1 I've read in a few forums that it cant be rooted. Or you had to downgrade firmware in order to root. I Was able to root & install TWRP recovery on my galaxy s5. Using Chainfires CF auto root for metro klte. And Odin v3.07 All while never fully booting ( stuck in boot loop) my phone.
1) powered phone to download mode.
2) connected to odin, flashed cf auto root. Phone passes unplug from computer.
3) phone boots up but stays on galaxy s5 boot screen.( never fully boots)
4) removed battery, put back, powered phone to stock recovery, factory reset it. Reboot, again. Still stuck on boot loop.
5) removed battery again, put back, powered phone to download mode, noticed knox counter was now tripped. 0x1, and phone status was now custom instead of official. Took a chance...
6) connected phone back to odin, flashed TWRP recovery img. Phone passes again, boots up but still stuck on galaxy s5 boot screen.
7) removed battery, put back once more, powered phone into recovery mode. To my surprise TWRP recovery now installed.
8) In twrp recovery did a full wipe, and flashed custom rom, and gapps. Now wife is enjoying her Cm 12.1 rom.
Was surprised to learn all this was accomplished without fully booting my phone ( sort of stuck in soft brick) and not verifying root with root checker app.

As long as odin says "success"!! Then you should be golden.
In fact your success might also be attributed to the boot loop not being able to auto-wipe and restore the factory recovery before TWRP had a Chance to take hold.
No doubt that TWRP contributed to the success of CF-autoroot for this device & 5.1.1 software combination.
Heres My story...
I too have the metro pcs galaxy s5 on android 5.1.1... All be it.. it's 5.1.1 now because of an OTA firmware update that T-Mobile released. I downloaded it because I intended to root the stock 5.1.1 android image..
( and that is what I achieved, two S5's fully rooted on stock 5.1.1 image, with custom recovery, and customized and de-bloated to my liking)...
I was previously rooted on 4.4.2 with this S5, So I flashed the stock T-Mobile firmware I got from samfirwares.com using Odin3 v3.10.6 to esentaly unroot and get stock 5.1.1.
My device having already been rooted before on 4.4.2, would not alow me to OTA to the 5.1.1 update that Metro PCS pushed via the network.... (My wife's non-rooted S5 however; was able to receive it via the network so I rooted hers the same way as mine following same steps minus flashing the stock firmware with odin after first using mine as the guinea pig.)
That said.. After first reboot of stock 5.1.1. Firmware I verified my fears and indeed root had been broken.
I then immediately returned to download mode and flashed TWRP via Odin, after reboot I then immediately booted to TWRP recovery and flashed the waiting CF-autoroot.zip I had placed on SD previously while on 4.4.2. .... So.. root was easily achieved
Thanks to TWRP..
If I remember correctly I did have the same need to pull the battery after flashing TWRP via odin.. due to hanging on the Samsung logo....
To sum this up:
1. I'M ON STOCK 5.1.1 WITH TWRP AND ROOT ON MY S5.
2. Knox is not tripped, (update its now tripped thanks to Titanium Backup... useless app in my opinion now that others can freeze/disable system apps. )
3. Because of the way that all of my flashing went without issue.. I never lost contacts, homescreen background, icon & widget layout, or settings. (I DID HAVE TO RE-ENABLE Developer Mode and USB debugging along with animation settings, also had to run "SD fix" again one time, but that's it.) I DIDN'T EVEN HAVE TO put my WiFi passwords back.
Ps I know most of that can be backed up and restored automatically. But I never had to bother.
NOTE: After each step following the successful flash of TWRP do yourself a favor and make a Nandroid backup to the SD. (U'll need at least 32gb to make 3 full incremental backups and still have space.) I suggest transferring them to USB or PC ASAP so that if u some how wipe the SD card U'll still have a way back.
I liked CM10 on my old phone... maybe now that I've made my nandroid backups at each step along the way I have little to loose if I try a custom S5 rom now..
Anybody have any ROM suggestions, they have personally flashed on S5?
Closing thoughts:
I full owe all of my success to the wonderful community of developers here on XDA-developer forums..
Without them and their strong following of loyal users, I would never have even attempted this on my S5.
Nor would I have been able to root my wife's unrooted android 5.1.1 MetroPCS Samsung Galaxy S5.
XDA has now helped me accomplish root on more then 10 devices over the years..
Thank you XDA, & a special thanks to Chainfire, Team Win Recovery Project, Clock Work MOD (for their help with previous devices), and all the testers out there.
THANK YOU ALL..

Im running this Rom at the moment. XDA dev. Albinoman's unofficial Cm 12.1 along with the suggested gapps and it runs flawlessly on my metro pcs galaxy s5. Haven't had an issue yet. You will find it in the xda forum under galaxy s5 unified development sub forum.
So far I've ran 6 custom ROMs on my galaxy, and this one seems the best so far.
Your rooting process was interesting, effective but interesting!
It's cool finding out new was this thing can be achieved.
Have fun bro.
STAY ROOTED....

Here is what I did to achieve root on my MetroPcs galaxy s5 on lollipop: I headed over to: http://www.sammobile.com/firmwares/database/SM-G900T/ and downloaded the newest FOJ4 firmware for the T-MOBILE VERSION of the s5. I flashed this through Odin. Then I went to: https://twrp.me/devices/samsunggalaxys5qualcomm.html and downloaded the Odin flashable version of TWRP. I flashed this through Odin. Then I headed here: http://xda-android-foru.blogspot.com/2015/11/rootkernel-root-method-for-foj4.html?m=1 and downloaded the version you can flash through TWRP. Move that file to your SD card on your phone and then reboot to recovery and flash that zip file. Boom you have now achieved root on your MetroPcs galaxy s5 on lollipop 5.1.1 albeit you now basically have a t mobile phone. Next thing you can do is just change your apn settings to those that MetroPcs uses to get your data and mms working properly. Just Google "MetroPcs apn settings galaxy s5" and follow the instructions on those sites that pop up. Hope this helps. I got tired of waiting for a release of a dedicated root method for the MetroPCS Galaxy s5, but there are plenty available for the T-MOBILE variant.

Rooting and TWRP on Galaxy S6 920I version.

I was able to gain root no problem at all but nothing works with getting TWRP to install. I found the right version flashed with Odin and it never boots. I've flashed the kernal as well for this device and nothing. I have the stock ROM so I'm good there but what do I need to do to get TWRP to install on this thing?

Phone is stucked in "Galaxy Note 5" screen

Hi,
I've been very disappointed with the battery life of this note 5 since it upgraded to 6.0. So I've decided to root it so I could install a custom rom and kernel.
I've followed this guide here:
http://forum.xda-developers.com/tmo...easy-steps-n920t-aoge-odin-twrp-root-t3187422
And now my phone won't boot at all!
I think I followed the wrong guide? The kernel I installed was "Noble_Kernel_Auto-Root_N920T_v0.1_Rebuid3.tar.md5"
I've managed to install TWRP and have access to it so I tried to flash a different kernel (arter97-kernel-n920tw8-4.3), but still the phone won't boot.
What can I do to fix this issue?
Thanks!
UPDATE:
I think I got it to work.
Thanks!
