I've read them.!!!

I've read the threads, etc... I CAN'T FIND a definitive

HOW TO ROOT A RETAIL SAMSUNG TAB P7510.

This being one that is WiFi only... Has no cell=phone affiliation AND

an updated rooting guide that was authored/update around June of 2011 (when the P7510 retail was released)

Different variants of the SGT have been around for a while and I don't want to brick my tab using rooting methods for older/different tabs.

So, I ask the question again. Can anyone point me to a rooting guide for the

10.1 INCH (WIFI ONLY) MODEL P7510 RETAIL SAMSUNG GALAXY TAB ??

And please don't say "try searching the threads"...

I HAVE!!! Perhaps I'm just to stupid to find anything that specifically addresses my question?!?

Any meaningful HELP would greatly be appreciated!

I know this is an older thread but it covers what I am looking for. I didn't find that the answer provided in here as the last post suggested was the solution. That video and how to is for rooting the device not unlocking the boot loader.

Does anyone know if you can unlock the boot loader for the non Google I/O GT-P7510 devices?

I really want to try out the latest CM9 image but I also don't want to never be able to go back on the upgrade path from Samsung.

I am hoping someone has a solution to unlock the boot loader for this non Google IO "p4wifi" device.

Hello,

after update to stock I9000XXJVP from samfirmare with MD5 check (Odin 1.7, 3 files rom, pit 512, with Re-Partition, auto reboot and bootloader update) all was fine until I reboot the phone.

I got boot loops.

I again flash the phone with the same rom and same settings as above. After first reset I have:

Successfuly installed package.

Successfuly copied media files.

E:format_volume: rfs format failed on /dev/block/mmcblk0p2

Data wipe failed.

Successfuly applied multi-SCS.

Then I choose wipe data/factory reset from Android system recovery (3e) and got the same error:

E:format_volume: rfs format failed on /dev/block/mmcblk0p2

then I choose wipe cache partition and hit reboot system now.

And again boot loop...

Please help, I'm searching for sollution from two days.. I tried to flash others roms but with same result...

Try flashing back to froyo or even ezy base froyo (preffered), then flash ginger rom with bootloaders, flash speedmod kernel (latest) convert everything to ext4 and do a factory wipe in cwm recovery, then custom rom. Works for me everytime.

You can always reflash with .pit and repartition, to fix such partition issues.
[Galaxy S I9000 Q&A, Help & Troubleshooting] mozambik:
I flashed with Odin with 512pit, re-parttion and bootloader update: 2.1 Eclair JM1, 2.2.1 Froyo JPU, 2.3.3 Ficeto_Deodexed_JVH_I9000_ODIN, and stock 2.3.4 JPU.. none of this work, every time boot-loop

I tried speedmod kernel and turn off all lagfix'es. Now all is in RFS.

Why I should convert everything back to ext4 ??

I think my problem is with internal SD-Card.. Flashing ROMs and KERNELs do not touch internal SD-Card.

From recovery I can't format internal SD-Card (memory):

E:Can't mount /dev/block/mmcblk0p1 (No such file or directory)

E:copy_dbdata_media:Can't mount SDCARD

[Galaxy S I9000 Q&A, Help & Troubleshooting] eggshaped:
I had this problem the first time I tried to install a new rom after rooting my phone. There's a thread somewhere with a solution (in the Dev section I think, if I remember rightly) which I followed and it worked a treat.

Just install firmware PDA-I900XXJP1 and pit file 512 with odin. Tick Re-partition. I'm not sure if any other stock firmware works but this is the one advised in the thread and it's the one I used, successfully.

This will get you back to an older version of stock Froyo. From there you can root again and flash an updated rom.

Sorry, it won't let me upload the files for some reason but they can easily be found in the stock rom thread.

Hope this helps.

Heres my pennys worth.

For the "Format Failed /dev/block issue

I had the same issue, 4 issues in fact:

rfs format failed on /dev/block/mmcblk0p2

rfs format failed on /dev/block/stl10

rfs format failed on /dev/block/stl11

Deleting meta data

Data Wipe Failed

I was giving up hope then

I tried this method:

I attempted to wipe all i could: dalvik, cache and data.

I flashed 'pit_512' on its own with repartition checked via Odin.

Back to download mode and flashed GB stock rom 2.3.6

Rooted, again via Odin

Then went into CWM recovery, went to 'mounts and storage' and formatted every option apart from the 'Format Boot' option. All formats successful which was different from before.

Formatting completely factory resets the phone so complete data loss!

Another flash with 2.3.6.GB stock together with the pit_512 repartition checked. (before reflash I did the 3 wipes again, Dalvik, cache, data)

After rom flashed I rooted then tried the formats individually again through CWM out of interest to see if I got those same 4 errors and BINGO!! all went without any problems!!! :good:

Might be worth a try??

:fingers-crossed:

Hope this helps.

[Galaxy S I9000 Q&A, Help & Troubleshooting] xsenman:
well you can but its not meant for your phone ( you might have problems), the ops file is what acts as the PIT for galaxy Ace, PIT is only used for some models, Galaxy Ace uses the cooper.ops For your model its either 4.38 or 4.42, that would flash correctly with cooper.ops.

Not my wish but that's how Samsung designed it, so try to search for Galaxy ace forum on XDA and learn from there how to flash..

I tried to set my router to 5GHz mode, and it wouldn´t find the WLAN even if I´m standing next to the Router.

I only tried 802.11n, not 802.11a.

But as others said differently I may give it another try. My Firmware is still KE2, maybe the updated the WLAN-driver later?

I´d actually would like to be able to use 5GHz, as there are quite a few 2,4GHz WLANs next to me, so bandwidth isn´t always the best.
[Galaxy S II Q&A, Help & Troubleshooting] fenrasa:
So, whats the case now? Are there several different Hardware/Softwarelayouts on the market or why are there these differences?

Just a follow up question to this:

It appears the GS2 does have 5ghz support at least to some degree.

Is this 802.11a 5ghz, or 802.11n 5ghz, or both? And on a side-note, what's the fastest speed you've got it to negotiate with wifi? On my Galaxy S, even with 802.11n and 10 feet away from my router, I usually max out at 72 mbps. :(
[Galaxy S II Q&A, Help & Troubleshooting] 3waygeek:
It definitely supports 802.11n at 5 GHz, as that's how I connect to my home network. I have no idea how fast the link is -- never bothered to check.

Now that I'm at home, I just connected to my 5 GHz 802.11n, and the link speed reported by the SGS2 is 65 Mbps, the same speed I get connecting at 2.4 GHz. I'm sitting about 2 meters from my access point, and the 5 GHz signal strength is only "good", as opposed to "excellent" for the 2.4 GHz.

well, for those who can't connect to 5Ghz band, try to adjust channel setting on your router may solve the problem.

My S2 only supports 36-48 channels currently, and I can't find any region option in the setting menu.

BTW, yes, the 5Ghz signaling strength is not as good as 2.4Ghz. However, the trasmission rate (or efficiency) is much better than 2.4Ghz due to less interfere.
