Can you give more details to what you have you installed on your phone prior to encountering this issue?Is your phone official upgraded to 4.3 and then rooted?or you rooted it when on 4.1.2 and downloaded a custom 4.3 ROM? Which ROM are you trying to flash?which recovery are you using?

[Q] Bricked Tablet - Downloading only

Hi Guys,
After playing with a lot of different roms on this tablet, i was content with CM12. I thought also now would be a good time to update TWRP from the ROM itself. So, i downloaded the TWRP manager, told it my device and told it to update. It asked me if the location for recovery was ok, and i (assumed....so its me being stupid) told it it was.......
Now my tablet wont boot anymore, i only get to see the "downloading" screen with the android dude. I love the android dude, but not so much that he's all i want to see
I tried using odin to re-apply the TWRP file from there, but it just is stuck at "initialization". I tried doing the same with the stock firmware from Sammobile, but the same thing happens.
I know there HAS to be a way to get it working again as it is still powering on...but i am running out of ideas. Can anyone please help me? If you're in town i will treat you to a nice Jopen bier
Thanks guys,
Yves

What Device you have? When you flash TWRP with Odin, do you uncheck Auto Reboot? I always uncheck it then power off then press Power, Home and Vol up to boot TWRP. Maybe no help.

Sorry, Samsung galaxy tab pro 10.1, sm-t520 aka picassowifi.
Auto reboot does not change anything... Still stops at 'initialization'.
I cannot get anywhere else but the downloading screen...
Thanks so far
I know you can't take the battery out but I been reading to let it die. Then plug it in works for some.
Note 4 Port Evolution 3.0
I drained it...when I get home I will try the Odin method. I'm starting to worry though....
Thanks again
Thanks for your help guys! The battery drain did the trick! I successfully installed the new TWRP and new CM 12.1
Thanks guys!

Glad it's working! :good:
How to drain battery?
Good to hear it worked for you but how did you drained the battery. I dont know how to drain it if I cant use the tablet ( and I believe my tablet is fully charged)
I am in a similar situation.
I have SM-T900 (Galaxy Tab PRO 12.2) and when I flashed TWRP 2.8.7.0 (for v2wifixx) for the first time over the stock recovery. It was successful and booted into recovery, but then it was not able to wipe any data. It gave some errors which I do not remember right now.
Then I tried re-flashing the same but it is not booting back into recovery, anymore after more than 5 attempts. When am re-flashing the TWRP, it is showing SUCCESS in Odin but the device is not booting into recovery. Current situation is that I cannot power it off nor boot into recovery. All it is allowing me is to get into download mode. Also, I have Kies 3/Smart Switch installed and NONE of them is recognizing the device in download mode either. However, am able to login to the download mode and reflash the twrp recovery image file.
Currently, opened the back cover and removed the battery connector and re-connected it and that is only way I could get the power off. I will try to re-flash TWRP again in the evening today.
I am posting here to ask for any other ideas. Is there anything else that I can try?
Thanks.

Finally fixed the issue.
I downloaded the firmware from www.sammobile.com for SM-T900 (Cellular South) having the PDA version as T900UEUBOI2 and this is for US. I downloaded the latest (v5.1.1) as of this writing.
I switched ON the tab in download mode and connected to computer using the USB. It appeared in Odin (I used v3.10.7). I flashed the firmware file downloaded (link in above para) and it roughly took 3 mins to show SUCCESS. Since, I selected the Auto Reboot in Odin, it tried to reboot but the device has been going through bootloop. At this point, I powered OFF the device and tried to boot into recovery. After couple of trials, it booted into recovery. I did a "wipe data - factory reset" an rebooted the device and it worked guys. I finally happy to see the device coming back to life.. however with the stock rom. However, I did not root the device as of this writing.
It worked finally. Hope this would help others.

Hi I am in a similar situation. I flashed CM12 on my Tab pro 8.4 wifi. Left it untouched for a month or 2. That mean battery fully drained. Then I tried to charged but no luck. The tab only shows a hollow grey battery icon with a static circle in the middle. Cannot boot to recovery mode but only download mode. No charging at all.
I tried the button combo like holding down power + vol up 20s, etc. No luck. I then bought a battery and changed it....shxt, same!
Then I used KIES to flash stock rom. A bit better now I can see the samsung text but freezed there. Anyone can help?

Bootloops After ODIN back to Stock Firmware

Hi guys,
I have the t-mobile s6 edge
After messing around with my device last night and this morning, I decided to go back to stock for a bit.
I have ODIN 3.10.6. I went into download mode on my phone. extracted the stock firmware from this thread: http://forum.xda-developers.com/galaxy-s6-edge/general/sm-g925f-s6-firmware-thread-t3078841
loaded the "G925TUVU1AOCG_G925TTMB1AOCG_G925TUVU1AOCG_HOME.tar.md5" file into the ap box for odin
connected my phone to computer, odin recognized it. hit start. ran successfully. rebooted, android guy came up briefly and said installing system update, then it changed to "Erasing..." then it rebooted again
now it's just bootloops forever after the tmobile screen. I can boot to recovery and it says installing system update each time I boot to recovery, but selecting reboot system there shows a no command error. force the phone to power off... power on again to bootloops.
tried to go into download mode again and reflash everything through odin, same issue!
I started last night by rooting using chainfire, then installing TWRPv2, then I flashed the 5.1.1 ROM available from @eousphoros (sorry for the tag, just thought you might want to be apprised of the issues in getting back to stock after using the 5.1.1 ROM).
with 5.1.1 loaded, smart switch didn't recognize the phone for a reset so I decided to go with the ODIN method and now i'm in bootloop city
any help would be greatly appreciated

You probably need to do a factory reset
In the future you should make a full backup before installing a rom

AHH!! Sorry to have made this post... here's what I did to get it actually boot:
reflahed the stock firmware through odin again, tried to reboot, it failed, obviously. rebooted to recovery, factory reset in recovery, power down option in recovery, then turned the phone on again and it magically worked!
hopefully this post will help someone who encountered the same issue

I had the same excat same thing happen when flashing this via Odin. I didnt need to Odin stock twice though . I just booted stock recovery and did a factory reset. After that I went ahead an powered down and rebooted . All good now
How long did you have to wait in the stock recovery to get past the "installing system update" screen? Mine just sits there and I'm unable to view other options in recovery.
EDIT for noobs (like me): wait 30 seconds on the "installing system update" screen.
I'm still stuck in boot loop
Im in the same exact situation , but I'm still stuck in boot loop. I followed your restore instructions and nothing. Please help.

Pp.
I initially used odin to flash OI1 update, after a rom I was using caused problems and I got bootloop. It changed bootloader value to b:3 and I'm unable to downgrade now so I used smart switch which didn't recognize device so used emergency recovery and still bootloop. I have factory reset and wipe cache multiple times along with adb side load and individual flashes of bootloader, modem, kernel, flashed custom kernel and twrp to access fix permissions and to mount partitions with advanced wipe etc and still wont boot past logo. Also during one fix attempt phone said can't mount system.. Idk I'm not understanding where the problem is .everything says successful but I'm still in bootloop. Please help. I've spent hours everyday for the past week searching & trying different things that seem might help so open to any suggestions.

Hi everyone
I'm new to the whole ROM flashing and using Odin. I had a bootloop problem and recovery mode showed all the options but has a green android man laying down with red icon above him and No Command below the android man. Tried the factory wipe and cache wipe but it gives some red writing with the word failed in the coding and the word error under the android man. Tried to flash a stock ROM from sammobile using Odin. Odin gives a pass but the same problems persist. Can someone please help?

Is there any solution for boot loop in gt-i9192?

Is there any solution for boot loop in gt-i9192?
My phone was rooted. I was using s5 rom proyect and my recovery was Philz Touch Recovery. I was happily using this rom for arround 8 months. Recently my phone was responding slow and my storage was almost full. One day while watching youtube videos my phone got hang! I just removed the battery and tried to restart. But there was a failure and no vibration. The phone is simply dead. I connected my charger and of :crying:course there was no indication. Later I went through several post to learn how to revive my phone from hard brick. I downloaded debrick.img file and made a bootable memory card. This time I was able to switch on my phone but it went through bootloop. The recovery mode takes too long to load and wiping cache and dalvik cache or even reset was not possible because of some error like E: failed to mount ......
Then I went into the download mode. and installed a firmware from sam mobile. Later I flashed CWM recovery through odin successfully.
But this bootloop still exists. Whenever I try to go into recovery mode it still takes a long time. And istead of loading CWM recovery it loads philz recovery mode that was previously installed
Please help I am tired

Dude,
I am also having a bootloop problem on my S4 Mini GT-I9192...
My TWRP recovery was working, I was using version 3.0.0.0 for serrano3gxx, but when I tried installing a custom rom, the right rom for gt-i9192!!!! for some stupid reason the twrp recovery keeps thinking that my phone is gt-i9190 !!!! it is so stupid!!!
for this stupid reason I couldn't install the ROM !!!
I decided to install the right recovery for my gt-i9192, so I downloaded openrecovery-twrp-2.8.7.0-serranodsxx-STABLE-signed
now, there was a warning to not install the zip using the recovery, but how could I install the recovery if I am unable to install anything with Odin!!!!
Nothing at all!!! I can't install anything with Odin, it just gets stuck!!!! So frustrating!!!!
And now afer I installed it said the installation completed successfully, but..... I can not even get the phone in recovery mode!!!!
What happened??? can anyone please help!!!
I am stuck in this stupid bootloop problem, and now on top of it I can't even go to recovery mode!!!! Nothing!!!
It is useless to do anything with Odin either, it recognises the phone, it says Added! but cannot install anything, it just gets stuck
WHAT CAN I DO?????
PLEASE HELP IF YOU CAN.
Check out
You can try this:
1. Download this file: openrecovery-twrp-3.0.0-0-serranodsxx-STABLE-signed.zip and copy the file in sd card
2. Then go to recovery mood.
3. Install the zip file from sd card.
4. hope you will be able to install the correct recovery mood.

I think you didn't understand... My phone is not going into recovery at all!!!
I had this problem once when I flashed an incompatible kernel, but I forgot how I got out of it. Best suggestion I have is take out the battery and put it back.
The "hard brick" you suffer the first time was likely a dead battery. The phone looks hard bricked when a battery is below critical energy, and not enough power is available to charge it with an USB. At that point, you had to wait for the energy in the battery to store up again, and then plug it into the USB to charge. Just a little power was necessary to get it charged again.
If you can still access download mode, flash the stock ROM baseband of your phone (you should know what this is). Your data will be wipe but at least you will be able to use the phone again.

Bro hard brick was not a low battery case. I kept it connected to the charger for almost a day. Can you please just say how to solve the problem. I am totally disappointed.

Bootloop - No Custom OS - No USB Debugging

Hello All,
I am using Samsung Note 3 Neo, unfortunately I have struck up with bootloop. I have read around and tried all the bootloop fixes but they all require the phone to have USB Debugging enabled prior for the fixes to work. Sadly for me, I didn't have the prior knowledge that that was available so I am stuck with a soft bricked phone with no work around.
Any help on issue is greatly appreciated.
Thanks in Advance
You can still access download mode (volume down+home+lock), right? Try flashing TWRP using odin ( i don't think you need to have usb debugging enabled) and then wipe everything and flash stock rom. Or if instaling TWRP does not work, flash directly stock rom using Odin. Hope that helps

I am not able to access download mode, I tried using volume down+home+lock button, Its not getting into Custom OS mode. Just black screen blinks and same samsung logo will come for thrice it will blink and then goes into bootloop
Hmm.. Can you access your stock recovery (home+lock+vol. up)? If you can, try doing factory reset and reboot. Not being able to enter download mode is really rare

Is your phone a Note 3 or a Note 3 Neo? These phones are two different variants.
Can you access download mode? (Phone off, press volume minus + home key + power at the same time until you see the phone starting to ask you if you want to procceed to access to download mode)
If yes, your model number is written at the top, download the latest firmware available for your phone model on samfirmware and flash it using odin, follow a tutorial if you are unsure cause you don't wana mess your phone up more that it already is.
If it cannot access download mode, this is gonna be a bit more complicated :/

[Solved] Alternating between TWRP and Samsung logo

Hi,
I was running LineageOS on my Galaxy Tab S tablet (SM-T800). I tried to update LineageOS. I went into the settings and downloaded the lastest version. However, the installation didn't go through. The download was successful, but an error message told me to try and manually install the update. I tried to go into TWRP mode to install manually the update. Instead of going in the recovery mode, I saw a TWRP app on the Google Play store. I tried and install that app. It went ok, however, I needed to reboot my tablet to finish. I did so, but after that, I got stuck in booting mode, between the TWRP logo and the Samsung logo. So the tablet was trying to boot in TWRP mode, but after about 5 seconds on the splash screen of TWRP, the spalsh screen disapear and then the tablet tries to boot in normal mode. It doesn't work, and the tablet reboots in TWRP mode, but, again, unsuccessful. It's a loop, alterning between the two splash screens.
I tryed to go into download mode and flashed the stock ROM (found on Updato) while using Odin on my computer. It worked. However, after the process, my tablet got stucked on the Samsung logo only. Now, it doesn't go in recovery mode (TWRP). I can only go in download mode or regular mode (but not working). Only the download mode works.
I don't really know waht to do. I tryed to redo the process with Odin and the custon ROM, but it didn't work better.
What can I do?
Thank you very much for your help!

The download was successful, but an error message told me to try and manually install the update. I tried to go into TWRP mode to install manually the update. Instead of going in the recovery mode, I saw a TWRP app on the Google Play store. I tried and install that app. It went ok, however, I needed to reboot my tablet to finish. I did so, but after that, I got stuck in booting mode, between the TWRP logo and the Samsung logo. So the tablet was trying to boot in TWRP mode, but after about 5 seconds on the splash screen of TWRP, the spalsh screen disapear and then the tablet tries to boot in normal mode. It doesn't work, and the tablet reboots in TWRP mode, but, again, unsuccessful. It's a loop, alterning between the two splash screens.
I tryed to go into download mode and flashed the stock ROM (found on Updato) while using Odin on my computer. It worked. However, after the process, my tablet got stucked on the Samsung logo only. Now, it doesn't go in recovery mode (TWRP). I can only go in download mode or regular mode (but not working). Only the download mode works.
I don't really know waht to do. I tryed to redo the process with Odin and the custon ROM, but it didn't work better.
What can I do?
Thank you very much for your help!

Have you tried to reflash twrp via odin ? If that works go into twrp reformat your partitions, then flash a custom rom.
Hi,
Thanks for your answer. I tried to reinstall TWRP with Odin on my computer. The process went well, but the reboot of my tablet that occurs at the end of the process got stuck again on the Samsung logo. It didn't get to TWRP mode. I tried to go manually into recovery mode by holding power+vol up+home, but it didn't work.
What else can I try? Thank you,

Are you trying to get to twrp from powered off state ? If not , get to power off state, then use key combo again to try to get into twrp.
Also when you flash twrp, in odi , there is a setting to prevent auto reboot, use that and try to get to twrp via key combo from download. Mode., finally tripple chech the key combo you are using is correct
Hi,
Thanks for the help. I tried to get to TWRP from power off state. The TWRP splash screen appears, and stays on for about 5-10 sec. After that, the splash screen disappear and the tablet reboot to get stuck on the Samsung logo again. It's like if the TWRP booting process doesn't go through...
Thanks again for your help,
Ouch !!
Looks like you got a real problem , and getting into territory I'm not expert in, Ashyx is the real authority with twrp for this device, you can try to pm him and hope he takes pity on you ( he has been helping guys on this qa thread tirelessly for over a year, and is prob taking a well deserved break ).
Otherwise a few more suggestions,
Maybe your PIT is messed up , ( but you prob would not make it to twrp splash screen in that case )
Twrp may still be trying to execute the script from the original linage update and not finding something bails ( total guess ).
Try flashing a stock ( downloaded from sammobile or somwhere you trust ) rom via odin, and see if you can get into the stock recovery. From there do a factory reset and see if you can get stock running.
Try getting into twrp with device connected to pc ( helped in some wierd cases, you never know lol ).
When TWRP splash screen comes up, try some key combos , maybe twrp checks for a script abbort key combo ?
Checkout the TWRP github issues page, see if your bug is there and a solution, create a bug report or mail a dev directly.
Have a look at the TWRP code, maybe some clues ??
Hi,
So not much development here...
I tried to download the stock ROM for my device from Sammobile and tried flashing it with Odin (JOdin actually, I'm on Mac), but it says it need a PIT file. I let Casual fin the PIT file and it finds it. Only, after that my device does not reconnect to Odin even though it's still plugged in my computer. I tried to unplug it then plug it back, but then Odin says the PIT file is corrupted. I tried to restart my device, but still not connecting to Odin...
I tried getting into TWRP with my device connected to my computer. Still the same problem of rebooting while TWRP is booting (while it's on splash page).
No combo key seems to work to keep TWRP open and loading...
Didn't find anything on TWRP github and I'm not saavy enough to look into TWRP code.
So, I'm still stuck with my initial problem. Do any of ou have some advices/suggestions or can help me with my problem please? At this point, I've been without my tablet for more than a month and it S**KS!!
Thanks in advance everyone,

Use ODIN via Windows or a VM on your Mac.
Flash stock firmware then boot to recovery and factory reset.
Reboot and wait ten minutes.
Hi, thanks a lot for your time.
I will try that at work tomorrow as I don't have Windows at home. However, I did try to flash stock ROM with Windows initially (see first post for more info) and it didn't solve my problem. I wasn't able to access recovery mode after the stock ROM was flashed. Hope it's gonna work now and I'll be able to factory reset.
I'll let you know tomorrow afternoon.
Thanks,
