Help needed unbricking my phone (Android system recovery <3e> KTU84P.A3000ZHU1ANK4)
Hello!
Newbie on this forum. Hope you can help me.
The situation is as follows:
Samsung Galaxy ACE 4 (SM-G357FZ)
While trying to unblock the network on my phone, i tried to root it (saw somewhere that this was a necessary step to unlock it).
I used the steps in this link: https: //theunlockr.com /2015/09/06/ root-samsung-galaxy-ace-4/
(just remove the spaces)
Used ODIN 3.11 , not sure if was supposed to do that.
During the flashing process, the following error ocurred: "Recovery is NOT SEANDROID ENFORCING"
I tried to continue the process anyway.
I ended up with a phone that can't function properly. It doesn't start normally, instead goes to system recovery and displays "Android system recovery <3e> KTU84P.A3000ZHU1ANK4" along the other options.
I can execute a factory reset and phone will function fine (goes to normal screen, executes everything etc) but as soon as i turn it off, same thing happens again. It goes to Android system recovery automatically.
How can i recover it? And after that, if possible, how can i unlock the network lock and root it?
Thank you in advance
Same problem
I had the same phone for 7 months. and It also had the same problem. Well, the solution is simple. Just flash a new Stock ROM, and no problems whatsoever. And just root it. I did it myself. Works like a charm

Edit: I have solved my problem.
I was able to Flash fastboot back to stock using RSD Lite.
I rooted using my original method and used Boot Menu Manager (Google Play Store) to install a custom ROM.
Worked like a charm!

The problem with this device is that it is almost impossible to find relevant information. The information that seems relevant may be outdated or wrong.
Here is my problem:
my xt910 is running stock 4.1.2 OTA Fido. I successful rooted using this method.
I attempted to install CWM Touch (here)
but due to a lapse in judgement I installed the APK and ignored the following warning in that thread.
"[Razr xt910 using Bootstrap BootMenu]
***do not install CWM Touch or uninstall hjack and BootMenu completly first.***
***If you install over BootMenu this cause black screen on Boot recovery***
***Boot Menu is advanced system of dual Boot and recovery***"
Then, when i loaded CWM, touching "backup/restore" didn't open up a different menu, I was stuck at the CWM main menu.
So I turned off the device, and booted it up normally to check things out. Then I get stuck in the "Encryption Unsuccessful" Boot Loop. I tried to boot into recovery and to no avail... I see the dead Android symbol.
I googled to figure out how to fix Encryption Unsuccessful, and saw a bunch of people mention RSD Lite and AP fastboot to fix Encryption Unsuccessful. I installed RSD Lite 5.7 and attempted to flash: 9.8.2O-124_SPUL-18_Fido_P006_A007_S1FF_CFC.xml (most recent I could find)
RSD Lite got hung up on step 14 "authentication" or some similar word). I rebooted the phone. Now my normal boot is stuck at "AP FastBoot Flash Mode (S) (Flash Failure)
I realized I was following out dated guides, and that the different versions/information were causing me a ****load of confusion, and leading me towards possibly permanently bricking the phone.
My current Boot Menu
Normal Power - Flash failure (as mentioned above)
Recovery - (Broken, as mentioned above
AP FastBoot - Functional (afaik)
BP SPF Flash - Functional (afaik)
BP Only - Motorola Logo after 5 mins
BP HW Diag and Boot AP - same as below.
BP Tools - Boots into android (all user data wiped - SD Card had to be reformatted)
If anyone could please help me sort out the BootLoop and install CWM. I want to get CWM running so I can install a custom ROM. This is my friends phone, and I am currently in a really tight position to get it to him... in working order.
I know a lot of you guys spend your free time helping idiots like me, and often expect nothing in return. I'd be more than happy to throw a few bucks, PayPal, towards anyone who wants it, and is able to take their time to solve my problem.
Thanks,

I'm not an expert in Android, nor am I an expert with computers, just an average joe in the Android world. Since the time I got myself into this community I never stopped learning something small. I was able to root my phone, install custom firmwares, unroot my device, do a NANDroid back up. All of this done with the help I got from an online source. Now, I'm looking forward to do further tweaks in my device's system. It might sound risky, but I'm enticed by how far an android device can be further improved. But before I do any of this, I'd like to know the appropriate steps to do when something goes wrong like what if device ends up on boot loop.
Questions:
1) What is boot loop?
2) What causes boot loop?
3) Is it the same with a bricked phone?
4) Can the phone be recovered from it (boot loop / brick)?
5) What should be done when a phone is on boot loop?
I humbly ask everone to share a bit of your knowledge about this.
Thank you.
1 - Is kinda of obvious. Bootloop is when your device is stuck at some of bootscreens (model screen, Samsung logo screen) and it doesn't boot properly. Even if you remove the battery and insert it again to turn it on, it doesn't turn on.
2 - There are various reasons: incompatible kernel, incompatible rom, edits on build.prop, rom poorly flashed. And, for our device, if you try to reboot into recovery directly and it has CWM installed, it may enter on recovery bootloop.
3 - I''d say it is a "soft bricked phone". If you has access to recovery or download mode, congrats, you can undo the mess. But if you can't, you got a hard brick. So, it will need repairs.
4 - As I said before, if you has access to recovery or download mode, it is possible to recover it.
5 - It depends. First I would undo my last actions. If I don't have success, I would reflash stock rom, it's almost guaranteed.
So, it happened to my phone when I attempted to do a "Recovery Back Up" using "[ROOT] Rashr" app. I had a Recovery Boot Loop, which boots only into Recovery Mode. But it's fixed now. Here's the thread: http://forum.xda-developers.com/grand-quattro/help/s-o-s-device-boots-cwm-t2981980
This is a reference for those who have the same problem.
I have a a Lenovo Yoga 8 B6000. Im running 4.4.2 and after some fiddling, used Vroot to root, and subsequently went through some arduous steps to finally remove the Vroot and replace with SuperSu. Life was good. Then I got a little careless when removing some of the bloatware and ended up with a constant boot-loop problem. And of course, no backup. (whoops!)
I have been researching this the past 2 days for a workable solution and am reaching out for some more refined assistance.
Here is what I have done thus far:
When pressing Power + VOL+/- I get to the initial recovery menu which gave me: Recovery, Fastboot, and Normal. After selecting the "Recovery" mode, I get the "No Command", after which I pressed the power button one more time and got into the English recovery menu. I show
Android System Recovery <3e>
B6000_A442_001_026_141117_WW_WIFI
Reboot System Now
Apply Update from ADB
Apply Update from SDCard
Apply update from Cache
Wipe data/Factory Reset
Wipe Cache Partition
I attempted to wipe the cache, followed by Wipe data/Factory reset. Following this procedure, I remained in the boot loop.
I installed ADB Flashtool drivers for WIN7 and attempted to use flash tool which was also suggested on this site. I got a 4.2.2 ROM "B6000_A422_000_059_131219_WW_WIFI" from a russian lenovo forum site to use with the flash tool and because the tablet continues in boot loop when starting, there was no loading of the ROM from that method.
I put the rom on an SD card and went into recovery mode. The ROM was not visible by the recovery menu (By that I guess the Apply Update from SDCard is looking for a specific file extension, which is not present).
I may have tried a few other things which are not popping into my head at the moment.
Im kind of at a loss and looking for any ideas from the gurus out there on how I might be able to get any kind of ROM to flash onto my B6000 and getting it up and running again.
Thanks
I was able to successfully fix the Yoga 8 tablet by using the instructions here:
//aluk4rd.wordpress.com/2014/09/08/an-easy-guide-for-restoring-your-stock-4-2-2-firmware-on-your-lenovo-yoga-tablets-8-and-10-b6000-and-b8000/
The trickiest part was getting the Mediatek driver installed. I use a dual booting MAC with WIN7 and sometimes there are some kwirks when operating in WIN7. However, the results of the instructions brought my tablet back to life, as well as downgrading to 4.2.2
Hi engineer2loggie,
How did you get that firmware? Can you tell where can I download it?
Thanks.
has anybody found a solution to this? im stuck with the same problem atm
Prologue- Before the bootloop and can't boot to recovery mode
So my ZH&K Odyssey Spin has been affected by malware and viruses. The effect of this is that I can't seem to "Reset to Factory Settings" and it just says "Unmounting Phone Storage". I even tried to enter to "Recovery Mode" and resetting from there but still no luck. Then I read about custom ROMs and flashing your ROM to remove malware and also rooting.
Chapter 1- The flashing, rooting and Custom ROMs
So I learned about rooting my android phone to gain more "admin" privileges and to be able to delete the bloatware in the stock ROM that ZH&K has but I noticed that the virus is included in the ROM so that gave me an idea to download a custom ROM and flash to my mobile phone to remove the bloatware and viruses. I tried doing the SPD Flash tool(UpgradeTool/FactoryDownload) and mounted the ROM for ZH&K Odyssey Spin (My phone hehehe ) and when I started the operation it just sat there doing nothing. So I researched more and found out about the ADB and fastboot methods of flashing ROM. I wanted to to flash TWRP Recovery into my phone but there was no TWRP Recovery available for my device so I "accidentally" downloaded the TWRP Recovery for Motorola G Falcon and after flashing to my device I noticed that I can't access the "Recovery mode".
Chapter 2-The "Bricking"
So when I flashed the 'TWRP Recovery for Motorola G Falcon' I cannot access the Recovery Mode. Take note that I learned about adb and fastbooting. So out of panic I typed "fastboot -w" (a command that wipes your data) into the cmd console. Then it happened when my phone rebooted it will show the "ZH&K" logo and play its animation and also has sound but after that it just stays that way and black screen and bootloop. So I tried to access the Recovery Mode(which is now unaccessible:crying and still shows the logo but does not go in but instead the screen goes black.
Epilogue- The "Begging for Help"
So I don't know what to do at this point and want some assistance for I have searched the net and there is no other problem like mine I even did the Battery pull method to "refresh" the phone but still no luck and some help will be greatly appreciated !
Phone: ZH&K Odyssey Spin
External: 8gb Sandisk
If you want to know something just ask thanks!!!
Hello everybody,
honestly i have no idea where to search for an answer for my problem.
Long story short:
The owner of the phone died and i searched for a solution to get the data (mainly images) from the phone. We could not enter so i tried the dr.phone - android data extraction (damaged device).
In the end of the process it tells me that: "Flash recovery package failed" and it is stuck at the "Recovering..." Screen.
Also on the screen is the message:
"Your device will be in the recovery mode all though the recovery process.
Tip: If the data recovery is completed but your device keeps in frozen stat. Please restart our product and connect your deice, the program will prompt you to exist recovery mode".
Now we dont know what we should do because nothing is working anymore.
We really need the data... Is there still a way how we can safe the data?
Did you get back the lost data you want ?
There are ways to recover the data but none will be found here.
Have a look here and you can do it yourself.
Don't ever trust iffy apps like that one to recover your data.
