A8 Bootloop - Samsung Galaxy A8s Questions & Answers

Hi, guys... Basically a little while ago a certain idiot attempted to root his phone, it all went wrong and said phone is now either dead or in the bootloop. I'm able to get it into download mode and thats all i can do! Ive tried reinstalling the stock firmware via odin however I haven't had any luck so far. It either straight up fails or gets stuck on NAND write start or setup connection. Can somebody please help because id really rather not have to go into a mobile repairs shop if i don't have to.

Hi! Were you able to resolve this issue? I have a similar problem. Thanks!

try to get your phone to out of battery, and use the charger to boot into the download mode, when charge it, press vol + - until you see the download mode, enter and flash firmware to get back to the original samsung UI

and if it stucks on NAND Erase try to find a new usb cable or try to find a newer firmware

the lastest firmware's bootloader have upgraded, if these solution wont work, i am afraid i cannot help you

New here and need some help

Hello,
I reciently rooted my samsung galaxy s2. I tried a few roms so i could get used to the system or restoring etc. However i encountered a problem whilst having a peek at an alpha jellybean rom, where i noticed that my CWM app on the phone had vanished? I attempted the restore using the 3 button combo and found that i kept recieveing E: can't mount/ E: can't cache messages whilst on the restore screen. i could find my latest restore on my sd card however it wouldnt restore. I believe the CWM was removed from my phone which caused it to not work. I was then stuck in a bootloop. no matter what i done, boot to a stock rom via odin, try the different CF roms i and try to put CWM back on to the phone? I read a post on here from someone who had the same problem, who was told it looked as though there is a problem with the partitions. i followed a tutorial and used odin to put Latona 20110114.pit on the phone. it said i would get a blank screen once this has done and i needed to remove then place the battery back in the phone then put it into download again. This didnt happen!! I done as instructed and now my phone wont go into recovery mode, download mode or even boot loop. I fear i have completely bricked my phone so i am trying to use oneclick heimdall to sort it however my PC keeps saying i need admin rights to install it which i have.
Can someone please help me out. I am new to this so please go easy on me.
many thanks
If you have no signs of life from the phone, it's probably cactus.
You might as well try a jig (but unlikely to work; still try one tho). Only option is service centre & hope they can't tell/don't care you've been messing with it & fix it under warranty or JTAG repair by a 3rd party repairer, at your cost obviously; will be cheaper than having Samsung/an authorised repairer fix it if they refuse warranty service which they're quite within their rights to do.

First result of searching suggests that's meant for the I9003. Good job.
HA
Hello,
Awe well then. never mind eh, whats done is done! Its totally bricked so i thought i would chance my luck by sending it back to O2 for repair. I was reading the only other way to get the phone running again was to take it to bits and hook it up for some stock flashing. so heres hopping they sort it!
lesson learnt!!!

Help with unbricking my phone!

I was using my phone at work 3 days ago during lunch and it was running fine. I was playing a new Kairosoft game. Once my lunch was over I put the phone in my pocket and I went off to work. When my shift ended I pulled out my phone and it was stuck in a bootloop with the Cyanogen logo. I rebooted it and nothing worked. I went into CWM to re install the ROM and it freezes every time. I used oden to try and fix it to go back and unroot my phone to start fresh. I stepped out of my room to use the restroom and my little curious nephew comes in and grabs my phone in the middle of an update. Now when I turn the phone on it says firmware upgrade encountered an issue. Please select recovery mode in Kies and try again. I downloaded keys and it didn't recognize my phone. I can't even get into clockwork mod recovery anymore. On Odin it has the yellow bar and when I try and flash the files I need to go back to stock it fails when it writes the NAND. I really miss my phone. It has been a while since I have been here. I don't know if my phone is a ICS. I got it last year. I have searched everywhere and nothing seems to work. I'll keep searching because I am determined to get it fixed but I don't want to flash the wrong thing. My phone still goes to Download Mode. According to what I have read it means that it's still salvageable. I hope so. Thanks for the help!
If you can boot into download mode then just flash a rom from there? Problem solved

[Q] Phone won't turn on nor enter download mode

Hi, I've been browsing the forums for people's attempts to fix a problem. At first the phone just turned off and I was unable to turn it on because it was stuck in a boot loop. The rom I had running was an ICS stock rom from hk. During this time i was still able to get into download mode but unable to enter recovery. I have tried many times to get to recovery and then tried to flash with several stock roms too. Upon failing around 10 times I moved on to a custom rom.
This one here:
http://forum.xda-developers.com/galaxy-s2/help/guide-26-12-flash-stock-firmware-rom-t2365701
The Jelly bean one here.
Upon failing from this too and unable to do anything but reset the phone and try again. I managed to turn it off... but now unable to turn it on in any way or get into download mode or recovery.
Is there anything I can try to do to get the phone to be working? What can I do?
Try a jig but understand it's very unlikely to get you into download mode. Service centre or local mobile repair shop for diagnosis (I also doubt it will be JTAG'able).
Edit - Also, search for KingRat's 'jump start' method where you try & boot the phone with just the charger/without the battery.

Don't loose hope mate...
Try remove battery and insert charger (optional)...
Press voldown+home+power button then let someone (your mother, father, brother, sister, neighbor or friends) insert the battery for you while still pressing those 3 keys...
I hope it will enter to download mode again...and report back please...
Try to use an other battery, my original one is fuked up, it does nothing.
I bought a new one and it works
I tried plugging my charger to the phone and pressing the 3 buttons and then having someone plug the battery in for me, still wouldn't start up. Also tried it with another battery i have on hand, also no luck.
You know what the options are then. Ignore people making ridiculous suggestions which don't work. My aim is to be honest with people, tell them the truth, and have them either get their phones fixed or replaced as quickly as possible in this situation (let's face it, nobody likes to be without a phone), rather than fill them with false hope & waste their time.
I think I fried my mobo while trying to flash it cause it does head up the phone without showing anything. I am going to order parts on ebay. I got this confirmed by someone at a shop near where I live, however they won't replace the mobo for me even if i do find a working one.
=) luckily this isn't my phone but my dad's who works at home and doesn't mind using an OLD OLD flip phone just for calls for the time being.
Side question, even if i replace the mobo and I get it booted but I still get stuck in the boot screen loop and unable to flash to any stock roms what can I do?
If you replace the motherboard you should fix it without further problems. New motherboard = new NAND, no more bootloop - unless you flash again & the flash is bad; you can't mitigate the risk of a bad flash, you can only do all the sensible things like making sure you're using a PC with reliable USB ports, that you're flashing the correct firmware for your device, that you're using an original Samsung USB cable. Basically, if you're careful, the risk with any given flash is very low.
So, fix the hardware problem, flash stock for your country/carrier once you've done that, and go from there.

[Q] Softbricked! Stuck in Odin Mode.

Phone Info: AT&T Galaxy S3, Cyanogenmod 10.2
So, I was messing around, trying to get the WiFi to work on my phone when I tried a solution I found on the forums: updating one of the files involving the radio. After flashing the file, my phone shut off and opened in Download mode. Now I can't leave download mode, can't enter recovery mode, and can't boot my phone. Oh, and my computer can't recognize the phone either. I've searched for hours looking for a solution and I'm freaking out. I seriously need some help with this.
Basically it says:
Could not do normal mode
Odin Mode
Phone Model, etc.
I really don't care how its done, what ROM I end up with, or anything else. I just need this phone to be able to work properly again. Thanks for any help!

That's sudden death syndrome right? Is there any good fix for it or way to get it replaced despite it being rooted and the ROM changed? (I did know that going into rooting might cause problems like this, just hopeful that there's a way)
Edit: If there's a way to get the phone to be recognized by a computer; I can still access download mode and would have no problem doing a full restore from there. I've tried installing drivers for the phone, it seems like the phone is unable to be recognized by any computer I try also.
Finally did get Recovery Mode to work. Don't know if that can help much

add a screenshot of recovery mod,download mod
SDS is when the phone is completely dead, doesn't boot at all.
You are posting in the wrong forum, this is for the i9300 only.
If you've flashed a file meant for another phone then you have probably hard bricked it.
If download mode doesn't connect to pc then you need a repair centre.

Solved the issue! So I managed to load my original ROM file onto my external SD and install it from recovery. For anyone else who has this problem, I just loaded the zip file onto the SD, stuck it in my phone, powered off and clicked Volume Up Home and Power to get into recovery, (phone specific for Gs3 on getting to recovery) and went to install from zip and installed the file. Problem solved for me, although it did wipe all the data which isnt a big deal really. Phew. That was a scare. And it fixed my WiFi problem, so all in all a good learning experience for me
Anyhow, thanks for all the help, I appreciate it! And sorry for hitting up the wrong forum, its my first time on it.
Thanks again!

galaxy S2 strange problem

It's my beloved I9100P. Last night it strangely failed. I realised in the morning when the alarm didn't go off. The phone was switched off.
When I tried to switch on, it got stuck in boot loop. The carrier animation and samsung logo will keep repeating. So I thought I will go into recover mode and do a factory reset. Phone went into factory mode the first time. I thought let me do a restart from there, just to see what happens. At this point, I noticed a lot of red errors on recovery mode screen, most of which saying something like "unable to mount /cache". I restarted it, but unfortunately the phone again went into boot loop.
Now when I tried, it refused to go even to recovery mode. I tried several times, but every time it got stuck on Samsung Galaxy logo.
It went into download mode fine, so I thought I will flash Orange UK carrier ROM. I downloaded the ROM and tried flashing with ODIN. ODIN recognised the device, but the flashing failed with error "Complete (Write) operation failed".
I don't know what to do now, have exhausted all option that I knew.
Any help in reviving my phone please?
@kaushal101 Keep yourphone phone connected to your pc and keep it in download mode. Dont disconnect it it could turn into a hardbrick which you can't fix without jtag repair service.
What you could do is see or you have installled all drivers, kies is disabled, right odin version. Google the problem and you would probably find an answer fast. I hope this message isnt too late..

Interesting. After trying several things, I did unplugged it from the machine. It shows the upgrade failed warning message whenever I try to switch it on now, which was expected.
I can still go to download mode and restart the ODIN flashing original Orange firmware process, but it fails with the same error. The only difference is, the first time it failed on CACHE step. Now it is failing one step earlier, at NAND writing stage.
Is there any hope? I had kies disabled etc., but will give it another shot. My phone was accessible with kies and I could also upload my development APKs from Android studio. So I think drivers shouldn't be a problem.
@kaushal101 I dont really have much knowledge about the s2 anymore, so the only good thing I can suggest is to google the problem and get more people to your thread here to help you and or find other threads about the same thing.
It is good that your phone can still go into downloadmode, I think there is still hope to fix your phone

Thanks for keeping the hope alive!
Have followed XDA's S2-ODIN troubleshoot guide, with no luck so far. Tried different versions of ODIN, reinstalled USB drivers, made sure KIES is removed from processes etc. None has helped so far. I'll keep looking!

Did you tryed another stock rom version?
Try other usb cable.
Sounds weird but try to leave the battery out of your phone for like a couple minutes
Try other usb port.
Try other computer:silly:
These are the things I can think of atm.
Have tried other USB port. Have tried a different firmware.
Am going to try a different PC today, will also give different cable a shot. But the cable I'm using is Samsung official one which came with the phone. And I've been uploading APKs using this cable fine, so am quite sure the cable is fine. But still, will give it a shot. Thanks for replying
