[Q] Tablet won't boot or install custom ROM - Transformer TF300T Q&A, Help & Troubleshooting

Hi all - this is bugging me as I can't seem to find the root cause or a fix.
TF300T was running CM11 nightlies - last update applied was 04/05/14 and worked OK for a couple of days but when I tried to cold boot yesterday, boot loop half way through start screen. I wasn't bothered too much as I had a full backup before I updated ROM - however, restored backup and it failed to restore.
So have been trying to get a ROM installed but just can't and it's really annoying me. I have tried wiping & fresh install with several ROMs (CM11 2xnightlies, Omni, SlimROM) but all give the same result - boot loop. I have tried using both TWRP and ADB sideload
I have tried with SDCARD removed and get error * failed to write data 'protocol fault (no status)' *. SDCARD seems fine (can read / write from PC) but will format it anyway in TWRP and try again.
Any suggestions welcome.
Device details;
unlocked bootloader
recovery - TWRP 2.6.3
ROMs tested - CM11, Omni, SlimROM
SDCARD - SanDisk Ultra 64Gb
EDIT - knowing there was something corrupt with storage / system, I flashed stock then TWRP recovery. Booted into Stock OK but once I tried to install a different ROM, failed again.

[Q] Stuck in recovery restart limbo

Hello all,
Last night I was trying to install the latest Gummy release on my Verizon Galaxy S3. This was the first time I have tried to flash a rom on this phone. It failed, and I rebooted my phone, and now it will only boot into the clockwork recovery.
I thought it may have been damaged as i was transferring the file to the device. I had an SD card in my droid X, So I put it in my Galaxy and formatted it with clockwork. Then I transferred the gummy release (that I also re-downloaded) from my computer to the SD card via a memory card reader. I put it in my Galaxy and tried to install the release, and it gave me a different error
Code:
E: Can't Open /external_sd/Gummy-2.1-01-09-14-NIGHTLY-d2vzw.zip
(bad)
Installation aborted.
Edit: Tried a few other roms and they had the same issue, but Cyanogen Mod 10.2 worked. Anybody have any guesses why?
Edit2: Further developments, Trying to do the latest nightly fir the CM yields the same issue that Gummy's release gave me initially. It reports as follows:
Code:
E: Error in /external_sd/cm-11-20140110NIGHTLY-d2vzw.zip
(Status 7)
Installation aborted
Is there possibly a firmware issue at play?
Did u unlocked ur recovery. And if ur trying to flash a KITKAT rom u need the latest clockwork recovery
I'm having this exact issue except I currently have TWRP 2.6.3. I wiped data, cache and internal and it actually booted the below ROM (the first boot) but once I got everything setup and rebooted the device it will not boot beyond recovery. It hangs on the Samsung boot logo. I've tried to restore to a 4.1.2 ROM as well as install 4.3 and 4.1.2 again multiple times but they will not boot. Any direction would be appreciated.

Sorry, forgot to mention, I did unlock with EZunlock. Would the clockwork on the play store be the latest one, or is there another place with more up to date versions?

Do you get the same error on install that I'm getting, ro are the installs finishing, but not booting?
Try goo manager or ez-recovery to install the latest recovery
right now i can think of
factory reset format data. Make sure u backup ur internal
Wen changing from rom to rom is a good thing to do a clean install
get the right gapps.
The 1st boot always takes time at least on me.
Sorry i cant think of more helpful things.. Been drinking
Looks like my recovery just needed an update. Thanks everyone.

Confirmed also an old recovery for me as well. Thank you very much!

[Q] Only fastboot accessible to flash / restore my TF700

Hello,
My TF700 was on a CleanRom (2.3 i think), for a while, i decided to update.
- I installed the latest CWM (via fastboot) and flashed a Cyanogen 10.2 "stable", but my tablet freezed very quickly after successful boot, i tried some reboots and get same problem.
- I tried to install a stock ODEX root ROM, the tablet freezed at asus logo
- I flashed TWRP instead of CWM, it doesn't helped
- I tried wipe data and cache with TWRP, then my data was not accessible anymore and TWRP was unable to re-create it
- I searched on forums and found on this one that flash a boot.blob file can solve the problem
- It doesn't and now CWM and TWRP refuse to work ....
So i post here before getting my tablet completely brick.
At this point, i get access to fastboot / abd, CWM load but don't work (reboot when trying to do something), TWRP don't load.
Any suggestion to get back to a Stock ODEX rooted rom ?
Excuse my english ...

Sounds like you are on an old bootloader. Flash the stock rom from asus by unzipping the zip you download from their website and placing in the root folder of your micro sd and then go into rck from the bootloader menu (power + volume down whilst booting)
Or you could just flash it from recovery....
lj50036 helped me to flash a new bootloader, recovery, rom and nvflash to make it unbrickable
Not just helped he spent many times to explain me how it works and what he did.
He is very nice and this was a pleasure to talk with him, i'm happy that there's still person like that on this planet
see you !

I buy a tf700 with cm 11 a few days ago i am really interessted on how this steps works. I really want to make it unbrickeable, But i dont really understand how it works. I can not enter in fastboot. at least i got cwm interface when rebooting with adb into recovery.
Can u explain how you did it?
It invovles flashing a modified bootloader and the flatline recovery and then using Wheelie to generate your nvflash blobs.

Stuck in boot loop, fastboot and recovery accessible
Hello,
I'm having a similar issue and I need help! Initially my tablet was rooted with Cromi-X 5.4. Then I decided to try Crombi-KK.
Here is what happened:
- Updated TWRP recovery
- Did a full wipe as recommended
- Flashing got stuck at the Crombi-KK loading sign
- Tried to reflash but TWRP wasn't detecting data partition anymore
- Instead installed the other recommended recovery CWMR.
- Flashed Crombi-KK, it worked. Played around with it for a few days, it was wonderful, fast and responsive.
- Battery died out and when I turned it back on I got a UIDs system inconsistent error.
- I found online many recommendations to reflash so I tried to do that
- Since then I'm stuck in a boot loop. I see the initial "bios" Asus logo then it restarts over and over.
- I am able to access bootloader and recovery
I've tried reflashing the asus stock blob. I've tried wiping the data through CWMR but it starts working and then it restarts. I don't know what to do anymore, so if anyone can help me, I would really appreciate it!
Thanks
Which recovery and bootloader version do you have now?
A (for KK) outdated bootloader seems the most likely culprit.
You can try save the recovery log when you flash or grab a logcat of the bootloop, but probably it'll only tell you that the recovery cannot mount /data.
Determine that you are on the correct bootloader, if not update it. If you're lucky the tablet will start right up. If it doesn't, formatting /data is the only way I know to get it back. Not just wiping - formatting it. You will loose everything on internal SD, so I hope you have a nandroid you can restore from later.
If you use TWRP 2.7+ be aware that formatting can take more than an hour. Let it finish!
For good measure, download CROMBi-KK again, check the md5 and then flash that file.
I'm on 10.6.1.14.10 bootloader which I think is the latest one
I have 6.0.4.7 CWMR
I'm trying to format data completely but when i do it in CWMR it starts and then the tablet reboots on it's own after a couple of minutes.
How can I retrieve the logs, I never had to do it before.
Thanks for your help
Mhh, getting a little more complicated.
Your BL is ok...
What do you see in CWM when you go into Mounts and Storage? What is mounted?
The recovery logs are under Advanced > show logs.
I'm at work now but from what I remember the only thing mounted was the cache. I'll double check tonight. Do you think there's any hope or I have a brand new paper weight?

Can you fastboot flash twrp?
It's much much better than CWM, has its own terminal and will be easier to offer the correct format command.

So I flashed TWRP and when I go in mount/storage everything is selected except for system. Should I do a format data from the wipe menu before flashing crombi-kk again?

To be in the safe side, yes, that is what I would do. TWTRP 2.7.+ takes a long time to format and it may seem the process got stuck. Give it at least 90 minutes to finish.
Then reflash CROMBi
I'm back up and running !!!
This time installing TWRP, everything was mounted (maybe my previous flash before CWMR wasn't good), did a format data, waited until it was done, flashed latest Crombi-KK and going through setup now. Hopefully won't have the same UID issue on next shutdown. I didn't enable fsync or journaling so hopefully it won't happen again.
Thanks both of you for your help!
Good deal! Happy for you!

[Q] SGS Tab2 10.1 (Wi-Fi) Boot loop + more

Hello.
First of all - I did try to search my problem but it is unique and I did not find the answer.
I am new to flashing ROM's and recoveries, but I do understand a little bit.
Here is my situation:
I bought a tab 2 10.1 inch wifi EUR version in a carboot sale for 20 quid. The guy showed me that it boots, and everything works, EXCEPT, it will do random restarts and sometimes drop the wi-fi signal.
When i got home it was running CM 10.2 something rather and it had a PhilZ 5.0 touch recovery. Obviously this was rooted. I wiped everything using odin 3.07 and it was restored to original samsung firmware and software. However the tab is either 1. Stuck in boot loop at samsung logo OR 2. loads to the welcome screen then freezes - restarts - stuck on boot logo.
I have tried to put a new recovery on it CWM 6.XXX but with no luck. When i try to install from SD card I get this error: E: failed signiture verification.
Anyone have any ideas what I should try to do now?
Thanks
Are you sure that before you flashed the new ROM you did a thorough reset and format of the system / data partitions? I've had similar symptoms from doing less than fully clean flashes.
Also I've seen lots of people have trouble with cwm (including me), so I've moved on to TWRP ( version at least 2701) or the Philz 6.something.
My best experience was with TWRP / full reset, format / omnirom for KitKat.
Good luck. Report back what works for you.

Will try TWRP recovery and see if that changes anything.

[solved] root/recovery borked since 6.0 update - can't apply 4.1 update

OK, so I've got the original shield tablet. I have lost root, and whenever I try to boot to recovery, the system attempts, goes to a black screen, then proceeds to normal system boot. Environment:
stock 6.0
non-rooted (not since updating to 6.0)
shield version 4.0
build MRA58K.41524_664.1902
previously had TWRP
I understand loss of root/recovery w/that last update is normal. However, I've tried:
flashing the new TWRP via fastboot w/o success (3.0.2)
flashing the rooted boot img w/o success
even flashing the stock recovery w/o success
ADB & fastboot commands chug happily along, & I'm left with the same behavior. Flashing the stock recovery actually gave me the dead android at the recovery screen (was this b/c I flashed the one for 4.0.1 & I need the one for 4.0?). So, what's my next move here?
Aaaaaaannnnnd.... I've also completely lost my WiFi. Says that it's on, but it's got the slash through it in quick settings & doesn't find any networks.

1) the twrp you linked to is for lollipop, states that in the notes section half way down the page.
2) to get root with this method you also have to install phh superuser
3) that dead Android IS the stock recovery
Now for help: flash this recovery(there are two here read and find the one for MM)

[RECOVERY] [unofficial] TWRP 3.0.2-0 (2.8.7.1 for Lollipop) [2016-04-05]
Sent from my SHIELD Tablet K1 using Tapatalk
Thanks Exile. I've got TWRP installed ok now, but it doesn't seem to be able to wipe anything - just kinda hangs there (trying to wipe dalvik & cache - just sits at "formatting cache using make_ext4fs"). It's also weirdly unresponsive with UI lag on button presses; not sure if that's a known thing. I'm assuming that the "E: Failed to mount decrypted adopted storage device" is in reference to my external SD card.
I also still don't have my WiFi. I've grabbed the WiFi full OTA from this post & adb pushed it. TWRP was able to successfully flash it, but then couldn't do the ensuing dalvik/cache wipe. I let it sit for a good 10mins just to see if it would finish, but it still sat at the same point. Force power-cycling booted it into the new 4.1/6.0.1 version, and I do have my WiFi back
So, how to get root back? Can I just flash the SU 2.65 I have from TWRP? Or do I have to flash the rooted boot img again? I do already have the Superuser app installed...

Ok, from here just flash the supersu.zip and you should be good. I can't remember if 2.65 works or not but I know you can find a copy of 2.71. someone else has a problem with 2.72 so it may or may not work.
As for twrp it has touch screen lag issues, I don't think any of the mm compatible versions have been able to fully fix this. I've had the same problem with dalvik cache and cache wipe, it is slow as molasses but will complete eventually. Once you have root I would suggest using a program called flashfire to flash zips and do things like cache wipe. It works like a charm.

Thanks again, Exile. I actually had to re-flash TWRP, oddly, but after some searching, I found a mirror for su2.71, & adb pushed it. Once I had TWRP back in order, I was able to then flash it & my root is back together.
Glad you got it working. Have fun and be safe

Issues with installing CarbonROM on the K1 -> Bootloop

Hello guys.
Last time I rooted and installed a Custom ROM was like 7-8 years ago with CM5 or so. So I'm not really up to date.
On my K1 tablet, I wanted to install the CarbonROM. Tablet runs Nougat.
The Root was successful, used fastboot for TWRP recovery. (Version 3.1.1 and 3.0.2, tried both). As in many tutorials described I wiped data/cache before installing. Installed CarbonROM (latest version) + gapps micro for 7.1 then wiped cache/dalvik and rebooted.
System then was stuck in bootloop forever, waited about 20mins but nothing happend.
Managed to backup by hard-reboot into recovery/adb and flash twrp again. Tried this time with twrp version 3.0.2, same issue.
I know about the presence of "blob", whatever it is. But since a few guides use it, and few dont, I tried with once with it but managed to land in bootloop again.
Tried with CWM but it didnt even recognize my SD card, or confused the internal storage as sd card. Moved the CarbonROM to the internal storage then and tried to install it. After boot image there was an android with a red "!" and "no command". Vol up + pwr -> recovery. rebooted. Still had the firmware from before, nothing happend at all.
I don't know anymore what to do to get CarbonROM installed and actually started.
Anybody got ideas or a actually a solution?
Greetings
Try a different ROM, or try another gapps (I've often had to mess with different gapps on AOSP ROMs on previous devices).
As for just getting the phone working again, you should have made a TWRP backup before trying to flash a custom ROM. Then you could have just restored the backup.
