Root Status = ROOTED
I cannot boot into recovery mode (but when i try i get this, look in pic 2&3)
Tablet Type = HKC (NOT HTC) p776a
ANDROID Version I think (98% shure) is 4.1.1 beta JB
What happened = A few years ago 2013 i think a got this tablet then i learned about rooting, roms, and such so i spent the next year or two trying to root the tablet. I finally got it rooted with a chinese root program and all was well (i don't remember the name of the program) then there was a update for su and i pressed the twrp/cwm mode on accident (I think I was talking to someone at the time) and now it does what is shown in the image 1 it is on some boot loop. When I try to access the hboot menu it does what is shown in these images 2&3. Also my tablet has a MicroSD card slot and the battery can not be taken out. the regular bootloop picture is image file 1 that is what it looks like when it does its continuous bootloop and P.S. the tablet turns off and on automatically during the bootloop. To try and fix it i have let it do its bootloop for hours on end turn it on and off tried looking for a compatible rom (to no avail) and let the battery completely die that is about it.

Okay. Just a few more questions.
Does your tablet boot into recovery (picture 1) even if you try to boot normally? (fastboot maybe)
Can you boot into anything else other than recovery? (try different button combinations)
Does ADB recognise your tablet when it's in recovery mode? (if you don't know about this, just post your computer OS and if you have ADB/Fastboot drivers installed on your PC)
If the anwser the the first question is no:
Does ADB recognise the device while it's in the bootloop.

sorry, i forgot to clarify the hboot. it pops up the "words" or whatever then automatically reboots there is no way to select options or keep the device on so i cant use fastboot unless there is a way i dont know of. P.S. the tablet restarts automatically so it is on for like 25 maybe 30 seconds then shuts off then turns back on and repeats till the battery is dead. My thought originally to fix it was to get a rom put it on the sdcard and see if that works but the manufacture does not supply the rom for my model only the p771a. and the only physical buttons are the home, power, the pinhole reset button, the volume and such buttons are virtual on the screen when it is fully on. And picture 1 i dont fully know what that screen symbol is the hboot one is similar but not that but yes it does but to picture 1 nomadder what i do even if i try to get to hboot menu. Sorry if this is a "little" scattered having explaining it. If it would help i can make a video and rar it and upload it here.

1. Download fixcache.bat.zip on your computer. Extract cachefix.bat from the file.
2. Run it. It should say just "Waiting for device..."
3. Now reset your tablet with the reset button and QUICKLY plug it into the computer and wait a few minutes.
Now try to get to that text in picture 1 and tell me what happends.
Also post the text you see on the computer from the file I sent you.
Tell me if

Umm, you said there is a reset button on the tablet so pressing that would probably reset it.
The error you are getting is because adb is not installed on your PC. Use this simple adb installer to instal adb. When installing just press yes to everything. MAKE SURE THE PHONE IS PLUGGED IN THE COMPUTER WHILE INSTALLING AND THAT IT'S ON!
Now run the file again.
If you want you can add me on Skype: janekmuric

If you want to know what is happening:
You are in what's called a recovery bootloop. It's when you can't get out of the recovery. What is happening in this case is that Superuser app tried to install it's binaries via recovery. Because some people don't know how to install binaries manually, the app puts a file on the cache partition so the recovery automaticly installs the zip upon booting. Now, this would be good so you don't mess up your device, but the zip file it's trying to install is faulty so it just breaks the device.
My attept at fixing this is to delete the /cache/recovery folder so it doesn't just install the file, and instead boots into a working recovery.

That would be great but i cant keep my tablet on for more than like 30 seconds before it auto shuts off and it automatically tries to go into recovery when i add power to the device it wont just boot to the OS

30 seconds is more than enough. Especally with an automated script like the one I sent you.
The first thing we have to do to fix your tablet is to establish a working ADB connection. Use the ADB installer i sent you. And look up on how to install Google USB driver for ADB.

ok will try

Can Internal phone data be transferred from a device with a broken screen? Read plz

Firstly, lets state the obvious. I know it can however I have ran into a few road blocks that I cannot overcome. This is what I know:
Phone: SGH-I727R Code named "skyrocket". Screen is broken however the buttons still light up indicating the phone has power. I have had this device for years.
Problem: When I connect my device to my computer, nothing indicates the phone is connected. I assume the "USB bugging" feature is turned off.
Solution: I have researched endlessly and turned up that this might be possible using Android Studio or Android SDK Tools by using a code to enable the device. I am not familiar with any type of coding and my fear is i might do more damage then good. The only reason I am trying to transfer the pictures is my best friend passed away recently. I know this device is quite old and nobody can probably help however I feel I should try.
Anything that can be done would be much appreciated.

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.

If you can boot into download mode flash the latest twrp recovery using Odin. Look for a .tar.md5 file, see Vincom's sticky in the development forum. From twrp you'll be able copy files from your device to your pc.

Thank you for your input. Much appreciated.
I downloaded Odin and the twrp file ( I belive). . I do have a question though. Wouldn't re installing the firmware delete the entire device?
---------- Post added at 08:01 AM ---------- Previous post was at 07:42 AM ----------
Also, I now have been able to see a icon come up. The icon indicates my phone however it only shows SGH-I727R, "Digital Camera" however i cannot access this.

You say you now have screen activity?

Hi uwannabananababy,
Thank you for the input. The screen does not power on however using the USB cable, my computer manged to pick up the device. The device is not labelled as a Hard drive but rather a Samsung Camera labelled as my phone model. SGH-I727R. I have loaded Odin however the program does not recognize it. I also downloaded Kies which does show it connected but it locks up on the connecting screen.
Could this mean that the USB connection is working (USB debugging mode is active). Maybe the device has a password that needs to be entered.
Could somebody explain what twrp means.
Thank you

Twrp is a custom recovery. It replaces the stock recovery and gives you more flexibility to work with your phone rile booted into it. The latest version shows mtp to work and you'd can copy and paste files from your device.
Sent from my Nexus 5 using XDA Free mobile app

Okay first things first you need to install a custom recovery. You can get everything you will need from the bottom most portion of opening (first) post in this thread. http://forum.xda-developers.com/showthread.php?t=1785999
1. What you need is to download and install this to your PC (ODIN 1.85 .. Direct Download) section 7, very end of first post. Extract the .zip to somewhere on PC and open ODIN. No phone plugged in just yet.
2. I tried TWRP recovery and couldn't get phone to mount so I used this recovery, it's all good. (philz_touch_6.48.4-skyrocket.tar.md5) section 5. I will give you the button combination so you can blindly navigate to the right section of Philz CWM recovery and get you mounted to PC. But not just yet.... Bare with me.
** 3. DO NOT! CHECK "REPARTITION" IN ODIN! YOU HAVE BEEN WARNED!! >
GETTING PHONE INTO DOWLOAD MODE(aka odin mode):
DO NOT TOUCH THE POWER BUTTON FOR THIS PROCEDURE.
Download mode is NOT the same as recovery mode
a. Remove and Reinsert the battery, have usb cable inserted to computer usb port but NOT to your phone until step (c).
b. ATT PHONES - Press and keep down both Volume Up and Volume Down keys simultaneously.
ROGERS PHONES - Press and keep down only the Volume Down key.
DO NOT RELEASE THE VOLUME KEY(S) UNTIL INSTRUCTED TO DO SO IN STEP (d)
c. While still holding the volume key(s) down insert the USB cable into your device.
The phone will turn itself on when usb cable is inserted. * DO NOT TOUCH THE POWER BUTTON *
d. When You see the screen warning you about installing a rom w/a yellow triangle RELEASE the volume key(s) ** (Stole this bit from Vincom's guide)
4. Now we are blind. We did not see part d. from above. But press volume up to enter Download mode. Odin should detect. Yellow com detects.
5. Click PDA button on Odin and find the file (philz_touch_6.48.4-skyrocket.tar.md5) you downloaded already. (And only this.) Click start. Flashes the custom recovery and phone will likely succeed and reboot. Mine did, I'm am doing this to my phone right now to be 100% sure.
6. Power down, aka remove battery. We will get this yet, lol.
7. Now we want Recovery mode, battery back in, usb attched to phone and PC. So button combo {{Vol up and Vol down and then power button on phone. Wait. We get a vibe, hold all 3 buttons for a leisurely count of 1 then 2. Let all 3 buttons go.}} We now should be in Philz CWM recovery after a few more seconds. PC will confirm with a sound and driver loading activity, did for me anyways.
8. Here's the blind magic, do this exact and it should work perfectly to mount your phone to PC. Be sure not to touch the screen all during these steps {{ Volume UP 1, 2, 3, 4, times, Power button. Volume UP 1, 2 times. Power button. VOILA success!!! }} I just tried this 4 times, it will work. PC sounds a connection, and my phones SD shows up in Windows file explorer, well both my SD's I have a micro inserted as well. That's about as close as I can get you friend, you'll get those pictures one way or another. Plus all of this is totally safe to do, and no you won't lose any of your data trust me. I even intentional messed up my first Odin flashing of the CWM just for a test, as this phone is no longer useable (charging issue) and I didn't care either way, been there, done that many times before. Thank you Samsung for Odin! Take 2 it went as planned. Success. Hope this helps, it has to!!!

All your files will be accessible with your PC as if it were a regular old removable USB drive or the likes. Camera photos are located within DCIM folder then inside Camera folder. Actually you can now save/move most everything from your phones SD storage to your PC.
## An MHL device and TV could actually be an even easier way about all of this now that I'm thinking about it. Network transfer/Bluetooth the files, slower of course. ##

^^ good stuff, i didnt have the patience to go through all the steps to write it out, good man.

Cool, no problem at all. Heck, tidy it up if you want (NVM had me a DUH! moment, LMAO), as it's a disaster compared to all of your awesome guides. (Best I've seen anywhere actually.) :good:

Hi, vincom, long time since I've posted on one of your threads. Thanks for the continuing support of this rather old gem.
Since this is a thread discussing broken screens, I thought I'd post here, since that's kinda my target audience.
What I'm wondering if is someone has an old I727 sitting in a drawer, collecting dust because the screen's broken, that they'd like to sell cheap (or give away??? ).
My problem is the opposite, I've managed to kill my motherboard on a phone with a perfect screen. I'd like to get the phone working again, because my girlfriend has a phone that--horror of horrors!--only makes phone calls and sends SMS messages. Being in Mexico, the only motherboards available here are for the International version, which is completely incompatible with the 727.
Also, if you have some important data on the phone you'd like to recover, I'd be glad to grab that off for you and send it back, assuming I have a successful install.
Let me know if this describes you, and we'll chat.
Thanks in advance!

PLEASE HELP ME with galaxy S2 SHW-M250K Boot problem

Please guys, my galaxy S2 SHW-M20K (Korean) is in trouble.
I bought it from a 2nd hand shop , and it was runing Android 4.1.2 Jelly Bean (rooted stock rom). I had no problem with it till today when I tried to install "CWM Recovery", After searching the web i found a post with two files that supposedly could do the task. These files are:
1. CWM_KT_M250K.tar
2. Tegrak-Kernel-Build-39-for-SHW-M250K-UE18.tar
Using Odin, I triedd the first file but it couldn't work, and the phone could not boot so i downloaded the "rooted factory firmware" and flashed the phone. Everything was ok. Later I tried the second file. Again the phone could not boot and stuck at the logo with a yellow triangle. After waiting for about 5 minutes I tried to shut it down by pressing the power button it did'nt respond. (Now this is a point that I regret), I removed the battery as a way of forcing to turn it off.
Now my phone cannot boot. It doesn't respond to power button, neither does it allow me to enter recovery mode nor download mode. But When i connect to the charger or pc, it start charging and keeps cutting off the charging frequently. But it only allows me to enter download mode when connected to pc. When I tried to flash the "rooted factory firmware", again, the flashing goes smoothly but when the phone starts rebooting it fails as if there is a power cut. Is my battery damaged? Can someone give me a guide on how to fix it?
I need your help gus, I am not an expert in the rootings and roms,
Pardon My English. It's a foreign language to me.

As u mentioned, I think that your phone has gone to a Soft Brick. I don't know much about the Korean build, so Google it to solve the Soft Brick. Try flashing the stock rom via odin but I don't recommend it since it may cause your phone to be hard bricked if not done properly.
So go to the service centre, you'll get more help there

I thank you sir for responding to this. From what you have said, I think the best decision is to take it to Samsung service center. (For I have tried to google it but I couldn't get a solution). I would also like to know if it is repairable, and about the cost, is it worth repairing or should I think of buying a new phone?
I am stranded.

$50 reward - Notepro P900 - stock - only boots to Logo then a blank screen

Ok so got a Notepro P900 - "stock" it only boots to Logo then a blank screen.
Tried recovery/reflashing but Odin just sticks on "initializing", I have seen threads saying to enable USB debugging etc but i can boot into the OS.
Can someone PLEASE let me know if I can save this unit?
I think it was is running 4.4.2. - obviously I don't care about knox etc, I would just like to get it running again
thank you
Edit: OK - $50 reward for anyone who can fix it.

can you boot into recovery mode?
Press and hold Volume UP key + Home Key, while pressing these keys then press and hold Power key for a while.
Release all key when Android or Samsung logo appear then you will see Android System Recovery.
Use Volume keys to select Menu.
Use Power key to Confirm.

Yes I can get into recovery mode. However that is as far as I can get. I have tried all different versions of Odin and it stops:

I'm not 100% sure, but I don't think you can do anything great there without activating debugging mode in the settings. Otherwise, you could pretty much bypass all theft protection.
... tried something similar after forgetting my screen lock but gave up annoyed after a while ^^
If it is the stock rom, it should be Android 5.1., right? Maybe you can post your thread in another, less specified section of this forum. Otherwise you could still try it in the forum Android-Hilfe.de at MisterX31. [I hope with this recommendation I do nothing undesirable in this forum !?]He has already helped over 200 people personally and individually with a 98 percent success rate without asking for more than a thank you.
Hopefully I could help you with this answer. If you already know something new, please let me know.

@TessTickles did you carry on trying or gave up?
Does Odin find it when connected in download mode (Vol minus, pwr, home together) to your PC?
In recovery Odin will not flash it.
Btw which Odin version did you try it with?

It is sat on the sideboard doing nothing. Odin finds it fine, it just fails to go any further.
Odin 3.07 -> right up to the latest version (and every one I could find in between)
thanks

And what was the battery capacity like when you tried?
Checked different USB cables and USB ports for connecting?
The right pic is what you see when connected?

Odin shows it like in the attached pic?
And says <Added> in the box below "com"?

but to name a few

So you just want to flash the recovery and keep the system?
I'd recommend to flash the stock lollipop ROM consisting of three parts.
That would be like a factory reset.
Then start again with rooting.
The three part ROM you get with SamFirm tool in checking the binary box.
Insert model and region and check automatic decryption as well.

Hi thanks for the reply - it was never rooted. I was just trying to get it running again, reset is fine.
Never used SamFirm before is there a guide anywhere?
I have also tried downloading the stock rom a few times and it always times out on places like sammobile - where can I get it?
thanks

Easiest way would be to use SamFirm.
May take a while to download ROM, but never timed out for me and it loads directly from Samsung servers.
Doesn't have to be installed just start it after unpacking.
No real guide needed imo.
Quite self explaining.
If you search for it in the net you'll find loads of pics showing what to do.
Just be sure to insert correct device type, region and check "decrypt automatically".
Here is a link to the original thread.
https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Don't care about "deprecated" because for all my six different Samsung devices it downloaded all the stock ROMs.
After downloading just start Odin from a desktop folder (c:/odin is best)
copy all three downloaded / uncompressed files into it
go into download mode (Vol down, home, pwr) with your P900 and Vol up for confirmation
connect P900 to PC
add the different files in their specific Odin boxes
don't uncheck "auto reboot" in options
Hit start and hope it'll work
It always did on mine when I sometimes mangled them up when flashing ROMs that produced permanent reboots or other probs.

Brill - I have downloaded the firmware - the file i got was "P900XXS0BPL2_P900BTU0BOL1_HOME.tar.md5"
I can open it with Winrar and I get a filelist of:
boot.img
cache.img
hidden.img
recovery.img
sboot.bin
system.img
Which are the three I need?
thanks again much appreciated

Ah
I'm sorry.
Forgot to remark that the "binary nature" box has to be set as well.
Plus the box "decrypt automatically".

Don't be sorry - I appreciate the help.
Did everything exactly as you stated... everything goes fine until I press start and then the Odin gets to "Initialization.." and thats it. Never moves, left it for an hour.
This is what happened before, tried everything and cannot get past initialization.
Thanks again

Well now we can just try different options.
Is Samsung Kies still running?
which Samsung mobile drivers do you use?
I don't have Kies and just use the mobile drivers.
Give older Odin versions a try as well.
The oldest one I have is the 3.04.
I just read that a repartitioninig with a .pit file might help, but that's quite dangerous to the device and should be the last option.
As long as the P900 is still reacting it can't be totally dead so there should be a possibility to revive it.

Do you have the possibility to do the whole process on a different PC?

Tried Kies a few times - it doesn't work. I can't remember what it failed though.

Might have bricked my phone (Alcatel Onetouch)

I rooted the phone to uninstal some bloatware, and of course I have uninstalled something I shouldn't have.
If think it was something with Lolipop in the name, which can sound pretty stupid since it's name of the OS, but the app (root uninstaller) told me it should be safe to remove...
Now either the phone doesn't start, or when it start the interface simply don't show up. I cee see the phone is running behind, If I press the power button I have the popup to restart or shut down the phone, and when I press the home button a google searsh interface appear, but I can't do anything else.
So I've been struggling all the afternoon to try to reset the firmware, I've installed QFIL, try to find the firmware, download some crap form internet that was useless since it was missing the prog_emmc_firehose file, which I've deducted should be prog_emmc_firehose_8916.mbn since the processor is a Snapdragon 410.
I found the file online, I setup the software, click on download, it load for some time... and then I have an error message (I put it on the attached image)
I have no idea what's the problem, if my files are somehow wrong or if the problem is elsewhere, since this model doesn't seem to be very popular I'm struggling to find anything. I think it's close the the Idol 3, but I don't know if both model are compatible.
I'm out of idea, if anyone can help I would greatly appreciate it.

Factory reset! By far the easiest option ( Maybe not actually... do you have any recovery installed? )
If you want to keep data you need to flash the full update image... It will re enable all the apps you disabled

If you're talking about pushing volume up + power and doing a factory reset, it's not fixing anything.
Or there's another method ?

There isn't , if you are android 5 once the app is uninstalled it's uninstalled permanently..> ( On newer android it's way harder to fully uninstall , so most apps just disable them )
To use QFIL I believe you need to enter EDL mode first? Look for some edl flashing guides , but if you can flash ANY custom recovery it's much easier that way

I think I am in EDL mode, otherwise QFIL wouldn't even start the procedure.
Just to be sure, I push both volume buttons down, then plug the cable.
Then I have a picture telling me I have to push volume up to enter Download mode, si I guess it's EDL ?

Are you saying I should be able to flash any custom recovery ?
Or that if I COULD it would be easier.
Frankly I have no idea what you're talking about, I'm totally in the dark here.

First I have limited knowledge about edl , but from what I know you can't enter edl with button combinations - download mode should not be edl... ( There are multiple ways of entering edl - You either need a special cable / Need to open phone , find test points and short them / issue correct fastboot comand for entering edl... I think it was something like fastboot reboot-edl )
And second, flashing system updates via custom recovery is usually a much simpler process than QFIL ( This is only a last resort option ! I'd use fastboot before trying qfil )
What you can do is find and download complete system update for your device , extract it and send me a screenshot. (If you can find a custom recovery for your device go ahead and flash it as well)
