[Q] Xperia Z tablet stuck in boot loop with partitioned sd card - Xperia Tablet Z Q&A, Help & Troubleshooting

Hello there, I have an Xperia Z tablet, originally 4.1.2 but now 4.3 (i hated lollipop so rooted it and flashed JB back on). Everything going fine but now internal memory full, so 'forgetting' I have 64GB sd card, decided to partition it so I could move/link various things to free up space. Used MiniTool partition (used before on phone), and created a second partition of 9GB size in ext3.
When I tried to recreate mount scripts in Link2SD, the tablet restarted itself (didn't get the option to reboot myself) and got stuck in a boot loop. I removed the sd card and it starts fine. So back to minitool wizard I deleted second partition and recreated it in ext4 - same procedure, same boot loop. I've since recreated it in FAT32 but still i get stuck in boot loop.
I read somewhere that ext2 is not fast enough, someone's guide said to create in FAT32 and yet another said only one partition on sd card should be FAT32??? Conflicting advice aside, how do I manage to recreate mount scripts successfully without boot loop?
Not sure what other info you need, but I have (obviously?) latest busybox and SuperSU installed, no custom ROM or CWM recovery.
Any help for a wee Scots lass would be greatly appreciated
Thank you.

Maybe SD card is faulty one

I've had the sd card for over 2 years with no issue, albeit not on a rooted device. However, wondering if it was the size of the card and/or partition that may have been causing an issue, i created a 2nd partition on a smaller card, 8gb, with 7.5gb / 2gb split on ext 2, but same boot loop. I am now thinking it is how the card is being partitioned that is causing the boot loop???

[Q] Newb trying to fix his G-tab

So heres my problem, had Vegantab 7.0.0 on a Gtab I just purchased online. I wanted the Vegantab on it because Ive seen it beeing used but have not done anything with ROMs prior to this.
When I got it, it was stuck in a Bootloop just rebooting the Vegantab screen.
-NvFlashed the tab,
-Now I got the Gtab and the birds as part of the loop
-Tried to reinstall Vegantab via SD card, Keep getting an error
What am I screwing up because this tab is about ready to go flying across the room.
Try repartitioning the sdcard while in clockworkmod recovery (which I assume you've installed to install VeganTab).
I've seen the Gtablet loop over and over at the bootanimation until that partition is repartitioned (2048 for first, 0 for swap).
I was able to load clockwork back on it but now am getting
cant mount dev block mmcblk3p1 Error
All I see is to change the command line? Which I have no idea what they are talking about
You better just nvflash and start with a clean slate. There's good guides on nvflash just search them.

NVflashing will probably not correct this problem. mmcblk3 is on your internal sd (2 partitions p1 & p2) which nvflash doesn't touch. The internal sd contains the /data partition & /sdcard partitions. I believe p1 is /data.
Two things to try (both accomplish the same thing...the first is the quickest).
1. Boot to CWM, go to Advanced & Partition SD, 2048, 0. This will attempt to wipe out everything on the internal SD & recreate the /data & /sdcard partitions or
2. Boot to CWM, got to Mounts & Storage & format /data & format /sdcard.
If that doesn't work, the resident expert on troubleshooting gtab internal sd problems is rajeevvp. If he doesn't chime in, you can PM him & he can have you do further diagnostics.

Boot loops new CM7 install

Hello!
I am having bootloop problems with CM7 (latest RC nightly).
I don't know what is causing the loops (at the CM7 boot animation).
The only think I changed was to reformat and repartition my SD card to a 4 gb EXT-3 partition.
Will that create boot loops?
You don't have a FAT partition at all?
Does it boot OK with SD card removed?

Thanks for the post -
I formatted the card with both FAT32 and EXT.
I tried booting without the card - same issue.
I resolved it by going to Advanced and unmounting the cache. That did the trick.
I wiped cache partition and Delvik and removed SD - still bootloops.
further advice?
edit: might help if I followed directions. will fix phone later

[Q] Talk, Trebuchet errors. Explain cm10 boot menu? iamafan's build

Hi all, I built my sdcard per: http://iamafanof.wordpress.com/2012/...r-nook-tablet/ (built by"Succulent")
My kids have two NT's. With two 16GB Sdcards, one class4 the other class 10. I know class4 is recommended, but one poster in forums said he's taken images of CM built on class4's and applied this image to class 10's in several cases and has had no problems. So I thought what the heck, can't hurt to try, so that's what I did (using Winimage). It booted fine 5 or 6 times for me, and I installed several APK's of games from Humble Bundle . I turned over the Nook to my little girl and she brought it back to me later showing she gets errors on boot, after swiping the lock symbol to unlock it. One is "Unfortunately, Talk has stopped". If you click OK on this, you get ""Unfortunately, Trebuchet has stopped". Clicking OK on this does nothing, it keeps popping up indefinitely. I don't know if the sdcard is hot pluggable (can be removed with power to the tablet), but she did admit to doing this. So I'm wondering if some corruption occurred to the CM build on the sdcard. Has anyone seen these errors? I could reflash it from the image I made off the class 4, but want to understand what happened so we don't run into it again. The funny thing is, I don't recall the startup wizard off the 1st class4 card prompting me with several screens regarding Google crap like it did on the 2nd card which was flashed from the same image. That was even after telling it I had no Google acct hoping it would leave me alone.
can anyone explain the boot menu you get when you press the N button? (I'm not including the faded selections) I'm wondering especially about the recovery options. Here's my menu:
INT BOOT ( I assume will boot to B&N native OS?)
INT RECOVERY ?
SDC RECOVERY ?
SDC BOOT (Iassume, boot to CM10 off sdcard?)
SDC ALTBOOT ?
START FASTBOOT ?

Yes,
internal boot - boots Rom in emmc
Internal recovery - recovery in emmc
Sdcard boot - boots your sdcard Rom.
Sdcard recovery - boots sd card recovery ( keep recovery.img in root of sdcard for it to load recovery)
Sdcard altboot - alternate recovery ( not necessary, unless you want both cwm and twrp at same time)
Fastboot - fastboot mode , fastboot commands to flash .img file etc with this method .
As for your problem, try entering recovery, wipe cache and dalvik cache partition (I've done this on emmc version, never tried sdcard version of any Rom) this may solve the issue. If not try factory reset.
And removing sdcard while device is switched on is called hot swapping , hot plug is a CPU governor. Not sure if sdcard roms are hot swappable, but I think not.

Thanks.
emmc=internal nook memory I assume?
Oh, and...just to clarify, I haven't modified (rooted) my tablet. (you mention factory reset). I should mention that with the sdcard out, it boots B&N OS just fine.
And the part you say about wiping the two caches, so I should go into SD Card Recovery to do that? Once you get into it, you have various choices like the ones you mention? (I'd read that this choice was to backup your NT to sdcard). And please, I want to be very, very careful not to wipe out the B&N stock OS, so please, any detailed instructions you can give so I don't make that mistake, I'd greatly appreciate it. (I see so many posts on these forums about people bricking their Nook tablets it worries me.)

Um I don't know much about how it works for sdcard Rom. I've always only used emmc version. I guess if you were to enter recovery, it would access the stock cache partition by default , and we aren't trying to clear that.
Try this - use titanium backup (only talking about your sdcard Rom here, nothing to do with your stock) and in options, you may be able to wipe your cache or dalvik cache.
Or,
boot into your sdcard Rom, in settings > backup and restore > factory reset. This will delete all user data and return Rom to original Cm10 that you flashed on sdcard.
Or if it's only google talk and trebuchet launcher issue, install a new launcher (go launcher, adw etc) , then use titanium backup to uninstall trebuchet and talk.

From what I see, titanium backup is an android app. If I can't boot to Android (Trebuchet error loops as I said) I don't know how I can install this to do anything? Nor can I install another launcher or go into Settings as the error doesn't let you get any further.
I guess if there was a way to browse files/folders on the sdcard partitions on the sd to manually delete the cache files.....but if they're linux partitions (ext3 or4) you can't do that under windows...

In cwm, enter mounts and backup, then (if) you see /sdcard /cache, mount that and format that ONLY.
Do not format anything else as some options can brick device (Rom, bootdata, factory etc)
Wiping cache is safe (99%)
Again, I have never used sdcard Rom so I don't know what will show up in your recovery. But if you see something like sdcard cache, it can be cleared. If it doesn't specify sdcard, let us assume it refers to stock emmc.

Select SDC Recovery on the Cyanoboot boot menu -- see steps 7 & 8 of the post at http://forum.xda-developers.com/showthread.php?t=2061536.
If you want to backup the BN stock ROM just in case, see step 9.

I chose sd recovery, chose Backup & Restore, then Backup. It started running right away. It said:
SD Card space free: 228MB
Backing up boot image
Backup of boot image completed
Backing up recovery image
Backup of recovery image completed
Backing up system
Error while making a backup image of /system!
I plug sdcard into PC card reader and the FAT partition has 0 bytes free. So, appears it ran out of space. I saw your comment about 600MB space being needed. So I'm redoing the partitions now.

Why backing up now when it's not working? Fix your issue, then make a backup. So the next time there's a problem you can restore to working condition.

Well, backing up, I think, was a good suggestion by Digimax. So I'm glad I did it. and now i know how to do it for future. Just in case anything EVER goes wrong, I'll always have that image now on my pc. Bad thing was, apparently B&N nook OS apparently keeps lots of APKs around after installing them. I had to make my 1st fat32 partition over 2GB for the entire backup to process without running out of space. backup size=1.6gb
I ran into lost chains - convert to cluster msgs trying to delete the folder of the first failed backup, but it never would delete even after a chkdsk, so I formatted the card and put the original image back onto it, adjusted the partitions, and then ran into a new probem.....the Cyanomod spinning logo never stopping spinning so it won't boot up. So I give up. I don't know if it's that it's a class 10 card that all these problems are happening. barring any other suggestions, I guess I'll make sure the other NT we have runs stable for a few weeks and if so I'll order another class 4 like that one has.

I don't know about your bootloop issue, but I don't think it's a sdcard class issue.
Anyhow, now that you have stock backup, aren't you going to consider flashing cm10 internally? Do you actually use stock?
Sent from my ST27i
I'm a little leery of it, at least while it's under warranty. I don't know how reliable recovery is.? Besides, my daughter wasn't thrilled with it being down for several days with me fussing with it and asked if she could have her "B&N boot" back I admit It is a bit of a pain having to pull it out of it's case, lift the flap, pop-in or out the sdcard to switch between them. (& also to have to remember to always turn it off b4 removing/inserting)
I may do it in the future though. Thanks for the help
FWIW, you don't have to actually remove the card to boot into stock. Just reboot, hold "n" to get into Cyaonoboot menu and choos "int boot" or something like that, and it will boot to stock with the sd-card still inserted.
Great, thanks for that tip!
Card died
I think many of these symptoms could have been caused by a dying card. It did have a corruption error once, and then it finally completely died. Just for anyone else that runs into these.

FWIW, /cache does not need to be backed up, which should help reduce the backup space requirement.

[Q] [CM9-NFE6.0] [P-500] [Link2sd] 2nd partition lose format at reboot

Hello everyone, this is my very (noob) first thread, and is a question.
I've started reading xda forums like 3 days ago, for like 12 hours each day... and its an amazing comunity of knowledge. Osom.
Well... ive been trying to set a 2nd partition on my 32gb C10 SD for extend internal memory with link2sd on my OptimusOne... on the way i learned how to mod, terminal mount and modify, recover, and all the stuffs that could make this work... but i surrender.
I can make it work formating SD with mini-tool partition wizz, conecting device to PC, and seting into USB massive storage mode (yeap! Worked indeed!!) but if i reboot 2nd Part. lose format and link2sd report error on mounting 2nd partition (says its invalid, mini-tool says it's unformated)... for re-mount i have to re-format with mini-tool and wipe the data... so i've avoided linking any app.
Readed about NAND lock (my device is by default unlocked), /system permisions, and others... and i simply cant make 2nd partition stays at FAT32. (yes, i tried with the other formats too, formated with CWM on recovery mode too and nothing).
Tried this too http://forum.xda-developers.com/showthread.php?t=1971689, and didn't work for me.
Last discover was that via Root Browser app, /system file has no "Sticky" permision, if i modify it then busybox and other apps fail and run into recovery mode... (had to reinstal everything several times)
I know there is some kind of permision that i missed... but could be kernel config?
The most simply thing and i cant make it work... ideas?

[Q] Troubles Mountin Sd Card

Hi,
Thanks for your kind help.
I was flashing my wife phone (a Samsung S3 i9300) with slim bean 4.3, i installed CWM, root it, do a titatium backup, everything great, i install from the sd card Slim Bean, everything just great, until i see that the android was not mounting the sd card, i went back to cwm and i can see the sd card with all it content when i choose install zip from sd card, but i can't mounting in android.
So using the adb througt linux, i could upload the cyanogem mod last rom and the gapps file i went back, i install it throught cwm and everything just great but i still can't see the sd card in android, i'm not sure if i do something wrong in cwm when i was trying to mount the sd card to upload the flash files from the computer to the phone.
I never see an error like it.
BTW my wife gonna kill me please help
I just put show log and i have the follow errors:
Can't Partition non-vfat: datamedia
Can't Partition non vfat: ext4
