Hi! Can some one help me regarding boot loops and rooting a device? when i tried to install the cm update and gapps and after clicking reboot system. Something like "Root access is missing, Want to root the device?" came up and i chose, YES, root the device. It then started to boot loop. What can i do to fix it? Thanks
Reflash ROM and always click "NO".
Its a broken feature of CWM.

Dear members,
I have been installing and using custom roms on my i9300 (32gb) for over a year now. just a few days ago, i installed a stock rom through odin after encountering a problem with wifi from one of the custom roms. The stock rom i installed is;
Version: 4.1.2
Baseband: i9300UBEMH1
BUILD: JZO54K.I9300UBEMH2
phone became smooth again with wifi problem resolved. however one problem arised..now i cannot install any custom rom. i tried rooting thorugh cf-root and installing recovery through odin n all other methods including the s3 toolkit. the root on aforementioned rom works absolutely fine but as soon as i try installing a custom rom through twrp or cwm, the system shows no error while installing but as soon as recovery reboots,the phone gets stuck on samsung logo.
please help!!!
Using latest philz recovery, wipe for new rom then format internal sd card. Install firmware then leave first boot for at least 5 minutes.
If it still doesn't work then check efs partition, possibly downgrade boot loader.

i would greatly appreciate if u can guide me or point me to the thread for downgrading bootloader...i think its the bootloader issue.

u could try another kernel like http://forum.xda-developers.com/showthread.php?t=2528624 and watch if the Devil kernel logo came or only the samsung logo.
to me its something of a partition problem..experts please share your view...
anyone???
I Have a LG Optimus L7 II p715 which i bought it a year ago,but i am not satisfied with its RAM and INTERNAL STORAGE so i tried rooting it
how ever i successfully rooted with a kingo root which is a one click process and when i deleted some of the bloatware my phone stucked with a booting throwing up a SECURITY ERROR but some how using lg user tools i installed a os again it is fine now !
My question is that i need more internal space so i would like to root again but i am worried of security errors so how to prevent this security error and what exactly throws up a security error ? will it again throw up a security error if i change the partitions for increase ROM and INTERNAL STROAGE ? or just tell me if my phone does not fit for rooting and all those benefits i get from rooting ?? thankyou for everyone in advance who are going to respond in this thread !!

after installing kdz file
u asked to flash upgrade superuser but when i enter recovery mode cwm mode is only available
should i do it with cwm ??
or first setup twrp mode and then flash super user ?
if so then i have to run twrp zip file on cwm mode or what ??
please bear with me I am a beginner hope u would help me?
On our device it doesn't matter much which recovery you're using since there aren't many ROMs made for it, and the ones that exist, i'm pretty sure, work with both TWRP and CWM. I personally flashed TWRP from neutrondev's thread. After that I was free to flash whatever I want. TWRP is just simpler to use, atleast in my opinion. Flash the TWRP.zip in CWM recovery, turn off the phone AFTER IT'S DONE FLASHING, boot in recovery again to make sure TWRP is working for you. After that you just have to follow the specific threads for whateve you want to do with your phone.

Hey folks,
I have a problem with my SPG621.
I used to have CM 12.1 on it. I rooted it and installed it via Dual Recovery.
I wanted to update to another Nightly but I got stuck in bootloop. I resolved this by flashing back to 5.0.2 to root it again with King Root.
I acquired root again and wanted to install Dual Recovery again and there is the problem:
No matter what I do, the tablet won't EVER boot into recovery. It just doesn't. I tried to flash a recovery via fastboot to it, and it says success but it won't boot into recovery.
Can anybody help, I would like to have CM12.1 on it again.
King root is BS
I suggest you root kitkat

But what does this have to do with the recovery?
I could solve the problem.
I flashed Android 4.4.4 to it, rooted it again with KingRoot and managed to finally get XZDualRecovery on it. Just strange that it did not work with 5.0.2 (it worked before...).
After wiping my device via TWRP I could install the altest CM12.1 nightly. Thanks a lot.
Hey guys,
I just tried to root my Acer Iconia One 10 B3-A20 (not A3-A20!!!) with Kingsroot and it kinda worked. I could grant root access to apps and modify some stuff, but unfortunately after debloating something went wrong and my tablet is in a bootloop. I performed a hardreset so I could start from the beginning. After completing the android set up I was thrown instantly to another bootloop. After some researches I tried to do the android set up but without the last step and I installed another launcher via playstore and email. Afterwards I could start and do whatever I want to do. Unluckily I'm again in an bootloop after I did a restart. I can't enter the android set up procedure anymore and can't install any apps from the playstore.
Right now I can do following:
- I can access the download mode and try to do something with adb, BUT I'm unauthorized and can't tick the USB debugging think as you can imagine
- Try to flash something via recovery, but untill now I could not flash anything
Does anybody have a suggestion? Stock recovery is still accessible, but somehow I can't flash anything.
Hope anybody can help me out.
Thanks in advance. Best Regards,
GerasVille
EDIT: It's solved and the thread can be closed.
Thanks to Shreps I could flash the stock firmware via stock recovery. Here is his post.

Hello, need help whith
I also had problems with kingroot, and decided to reset tablet "factory default".
The tablet would not start, loop on the logo. I saw this post, and download the "OS" official Acer ICONIA ACER ONE 10 B3-A20 and install it from a sd card and stock recovery.
Everything went well, the tablet starts asking me choose language, wifi network and login with google account I had before the reset. And here is the problem: I was not which account google it had before the reset, the tablet is 2nd hand and do not know how to solve this.
there any way you can skip this protection?
It is possible to flash a rom with spflash clean and able to put a new google account?
I'm bored to seek and find nothing.
Thanks in advance
