[Samsung Galaxy Tab Plus] Aeolian1916:
same problem I'm having with my Samsung Gt-p6200, it just boot-loops to the "samsung galaxy tab 7.0" boot loading screen and hangs.. these happened after i flashed my firmware from stock honeycomb to jellybean(the austria firmware, i think that's been posted in this forum).

here's what happened before the problem:

-I flash the stock honeycomb firmware with the jellybean one that i found here..

-after i flashed using ODIN, the new firmware works great, i was even informed that i have free 50GB worth of dropbox space,

the file was named P6200XXMC3_P6200OXAMC3_ATO

- I have used it for a day, until the battery drains and i have to charge, but when i opened it again, it already does this "boot loop" problem

- i have tried flashing CWM with ODIN(as i've read here somewhere that it might help) and do that wipe cache and factory reset thing but that didnt help solved the problem.

hope anyone could help me, im also thinking flashing it back to it's original stock firmware but I dont have a backup of that and I dont know where to get one, I've been searching the net for two days for that stock rom but all i found are the new jellybean ones and some old ones but is uploaded to hotfile which is now deleted or locked.

I hope you guys could help me out and thanks in advance!

try flashing a new , latest firmware on odin

just try it.
[Samsung Galaxy Tab Plus] jvgabs:
Hello guys! Im also having this same issue.

*Using the same firmware that was posted here in xda because i was having trouble downloading those official jellybean firmwares

*The battery got drained

then if i charge it, it will remain in a "blank slightly illuminated screen"

* after a few munutes, the tab gets really warm.

*but if i dont charge it, it will get drained again because it keeps on turning on itself back to this time to the "galaxy tab plus screen"

I cant access recovery mode.

I can access odin mode and can flash successfully with cwm or the same firmware back but the problem still persist.

I havent tried other firmwares though.

4 days passed already and i cant figure this out :(

Please help
[Samsung Galaxy Tab Plus] skurys:
So I had this happen to me yesterday, where it rebooted randomly on me, only to freeze on the Galaxy Tab 7.0 Plus screen. I had custom recovery (TWRP) don't know if that matters, but I was able to access it by holding Power+UpVol but keep it held. It would freeze on the same spot but since I was still holding the keys it reboots a second time and this time it would go into recovery.

I then wipes cache and dalvik, no go. Sadly did a full wipe. Still no going past the tab plus text. So I flash MF1 official 4.1.2 firmware (I was previously on 4.1.2 UK official) still no go. Put in latest 2.8 TWRP and booted into it still with some trouble as I mentioned above. Did another wipe and it then hung on blank screen or so I thought. Took a long time to boot and after a long time, and the Android is upgrading message, by some weird chance I was on the MF1 official rom but all my apps settings everything was saved.

Working 100% now and I still don't really know what the hell happened. But if this helps anyone then all the better!

Ive just receive my htc wildfire s from the repair shop after hard bricking it by myself, they manage to bring my phone back to access bootloader but still stuck on htc green and white logo when you just turn it on,they used jtag method..my problem is I dont know what firmware should i use to flash my phone and bring it back to stock gingerbread firmware..

here is my bootloader info :

hboot - 0.90.000

radio - 7.46.35.08

I dont have any ***locked*** or ***unlocked*** phrase on the first line indicated - (and ive read some articles in other forum that it is necessary to update the bootloader to have ***locked oow*** appear on my bootloader and update my hboot to 1.08.0099 - 1.10.000 and then unlocked my bootloader via htc.dev officially).

one more thing , ive tried flashing extracted ruu from football's post because like what ive said my phone is stuck on htc white and green logo when turning it on after a jtag...but my log says that "main version is older" ,, i tried it using goldcard and plain micro sd card.. So the big question is WHAT firmware or rom should i flash in order to use my phone again?? do i need to update bootloader first??? or what..what method should i use??? thus my wildfire s is still brick or un recoverable???
[HTC Wildfire S] crossfire77:
do you have marvel( GSM ) or marvelc(CDMA) phone? and have you installed recovery in it?
[HTC Wildfire S] bigthree:
my phone is htc wildfire s or marvel a510e and i dont have custom recovery on it.
[HTC Wildfire S] crossfire77:
okay.i really confuse about your problem right now.but what is situation of your phone right now?

is it working?

any rom installed in it?

if you can have any rom installed.you can download ROM MANAGER from play store and then from it,you can flash clockworkmod recovery.

and i will give you european stock rom 2.3.5 which is flashable zip.so hassle free.but you need recovery to flash it.

---------- Post added at 01:07 PM ---------- Previous post was at 12:59 PM ----------

your hboot is 0.90.000 so and you dont have any signs like locked unlocked on your bootloader menu.its meaning your phone is not rooted.

so for custom firmware you have to root your phone.and secondly if it's got back from service center it should be in working condition.if it's not.you can go to service center again.they people have stock firmware in sdcard.

they will put sdcard in your phone and install original firmware.then you dont need to root and all your phone..

Sorry :P but u in serious problems i had exact same problem and struggled in several days to sort it out

U efs dir is corrupted for sure - u should have made a fresh backup before starting any flashing :confused:

This is with no doubt the most complicated dir on our phone, and if u dont have a 100% working backup before starting messing around theres absolutely NO way to restore it - I was lucky i now a guy with a SPT box he hardcoded my modem bin file and imei, and then copy imei folder 1 file after another, then set permissions right with efspro - and then network/imei came back - but this way i cant ever change modem file again has to use the patched one (and it must be flashed through spt box not odin/heimdal it wont work then)

This means i ever cant flash a rom with aroma installer, because it forces u to choose another modem file:eek:

Sorry but without a spt patched modem u wont ever be able to use network again :rolleyes:

bricked s3

i bricked my s3 (hard brick, not soft as you are reporting), i sent mine off to mobiletechvideos.com and got it back within a week. HIGHLY recommended. don't know if you can fix your soft brick or not, but you may need JTAG repair like i did. i didn't have the hardware to perform the JTAG myself, but i had the software. needless to say, it was cheaper to send it off to be fixed than to report it to my insurance or to buy the hardware. hope this helps!

Hello, I've got the same problem here.

I managed to ODIN flash a stock I9300XXDLJ4_I9300PHEDLI1_PHE ROM with CWM root.

It keeps giving me this 'E: failed to mount /efs (Invalid argument)' error.

then I got in with ADB SHELL and executed:

mke2fs / dev/block/mmcblk0p3

sh: mke2fs: not found

I investigated a bit and found out that it's a busybox command, so as I only can ADB do things, (doesn't boot), i pushed the busybox_android binary to my S3 and now when I execute the mke2fs command through:

./busybox_android mke2fs /dev/block/mmcblk0p3

I get

./busybox_android mke2fs /dev/block/mmcblk0p3

Segmentation fault

Any ideas?

Thank you in advance.

Flash a stock rom via Odin .

[Galaxy S III Q&A, Help & Troubleshooting] ptolomeo:
I already did that but phone won't boot up. Is there any special recommendation/procedure to fix this?

I flashed a stock I9300XXDLJ4_I9300PHEDLI1_PHE ROM with CWM root.

In the Galaxy Note N7000 we had 'full wipe stock ROMs', I wonder if there is anything similar in the S3...

Thank you in advance.
[Galaxy S III Q&A, Help & Troubleshooting] ptolomeo:
We finally fixed it. I'll post the solution in case it can help anyone else...

The S3 got stuck in the Samsung logo screen:

When entering the recovery it gave us this error "E: failed to mount /efs (Invalid argument)"

As we already know, the /efs folder contains all the personalized information of the mobile (IMEI number, carrier lock, etc). So if we like to play with ROMs, we should be aware of this detail and make several backups of this VERY IMPORTANT folder, and preferably store them out of the mobile, in the computer for example.

in case we mess up the /efs folder, we are likely to have no other solution than bringing it to the authorized Samsung dealer for repair. No one is going to lend us the EFS backup from their mobile, as doing that we would likely clone their IMEI -which is, BTW, unlegal.

So we first flashed with PC-ODIN a STOCK ROM (I9300XXDLJ4_I9300PHEDLI1_PHE). We tried different ones (one file, 4 files) and none of them solved our problem as the problem was with the /efs partition and I don't think any ROM will touch that...

After flashing the ROM we also flashed Chainfire's CF-Root (CF-Auto-Root-m0-m0xx-gti9300)

We boot up the mobile in recovery mode (Volume UP + Power + Home), we connected to the PC through ADB SHELL.

Our first surprise, trying to partition:

#mke2fs / dev/block/mmcblk0p3

sh: mke2fs: not found

It seems that mke2fs is a command provided by busybox, and it's not present in the stock ROM.I downloaded a precompiled busybox version from busybox.net and pushed it in the S3

PC> adb shell mkdir /data/busybox
PC> adb push busybox /data/busybox
PC> adb shell
$su
#cd /data/busybox
#chmod 775 busybox
#./busybox --install

once installed we could use mke2fs command properly:

# busybox mke2fs /dev/block/mmcblk0p3
busybox mke2fs /dev/block/mmcblk0p3
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
5136 inodes, 20480 blocks
1024 blocks (5%) reserved for the super user
First data block=1
Maximum filesystem blocks=262144
3 block groups
8192 blocks per group, 8192 fragments per group
1712 inodes per group
Superblock backups stored on blocks:
8193

and after that mounting the partition in the /efs folder

#busybox mount -w -t ext4 /dev/block/mmcblk0p3 /efs
busybox mount -w -t ext4 /dev/block/mmcblk0p3 /efs

With the EFS folder fixed, we ADB PUSHED the backup of ur efs folder (efs.tar), we unpackaged it (busybox tar xfv efs.tar) and moved it's content to the newly fixed /efs folder.

Reboot and ready to go:
[Galaxy S III Q&A, Help & Troubleshooting] Rockwell_:
I did everything as told but after that command I get this:

mount: mounting /dev/block/mmcblk0p3 on /efs failed: file too large
[Galaxy S III Q&A, Help & Troubleshooting] ptolomeo:
You're on luck.

In the Spanish forum where I also posted the solution (www.htcmania.com/showthread.php?t=541264), another guy came with the same problem. In his case, he was using latest busybux v.20 which he downloaded from busybox.net instead of using the one I provided (v.19).

http://www.nobutaka.es/web/files/S3.zip

We substituted v.20 with v.19 and it worked instantly.

Hope it works for you.

Offtopic, but how did you manage to mess up EFS at first.

I am asking, so taht I can avoid it in future.
[Galaxy S III Q&A, Help & Troubleshooting] ptolomeo:
I didn't mess the EFS. I don't even have a S3 (I have a Note N7000) .

My friend claims that he also didn't do anything at all. The S3 just drained the battery and then it didnt boot any more.

Hope it helps.

My conclusion: if you own an S3 do a backup of the EFS folder.
[Galaxy S III Q&A, Help & Troubleshooting] Rockwell_:
Ok, I see. Thanks.

Now I get error after ./busybox --install

edit: Got it working after removing the new busybox and mkdir /bin

Now the only problem is restoring efsbackup.tar. I have two different backups. Others size is over 6MB and other is 5.3MB. Should I do something with the .img files? I tried to push the smaller one in to phone and unpacked it in /efs folder. Still no IMEI.
