Boot-Loop after OTA3 - Thinkpad Tablet General

Hi,
i think i just bricked my TPT - or at least i just don't know how to recover from the boot loop. first of all what did i do:
I've been @ 0065_WE, device was rootet, OTARootKeeper was applied.
Since i've removed lot's of lenovo-bloatware i wasn't able to follow normal upgrade path so i had to restore the APK's (thankfully they were provided here).
Then i did a wipe data/factory reset and manually applied the OTA2/2.5 Updates in the following order (downloaded from download.lenovo.com):
A310_02_0037_0076_WE
A310_02_0039_0089_WE
TPT booted, all fine - so i downloaded the OTA3, went to recovery again, applied it, all went fine, but now i am stuck in a boot-loop. On startup Lenovo logo shows up, stays for about a minute, then device reboots. After 3-5 reboots display stays black. What i am also worried about is, that probably my battery will discharge and i do not seem to be able to charge it - after i plug in the stock charger the battery icon appears but the tablet seems kind a stuck - if i remove the charger the battery icon stays... i have to reset the device using the button next to the SD card.
Since there are no full system images from lenovo the only solution i can think of would be flashing CWR and applying a nandroid backup. But as far as i read here CWR is NOT working with the ICS boot loader - so do you guys have any idea how i could get the TPT up and running again? Did i do something wrong? I thought applying stock update.zip's using stock recovery should be safe...

Hello
Try the following.
The tablet should not be plugged.
1: boot in recovery mode.
2: Delete cache partition.
3: Press and hold the reset button for 20 seconds.
4: Turn on Tablet.

Well, i followed these steps, now the TPT is not boot-looping anymore, instead it stays at the lenovo screen...
i also did a full-wipe, wiped cache, re-installed the ICS update, rebootet, re-done your 4 steps, doesn't change... my only hope would be to be able to install CWM using stock recovery and re-flash it with a nandroid backup...
but as far as i know there's no cwm for ics yet... so any other ideas?
and another side-question: is the TPT charging while in (stock) recovery?

No other idea, sorry.

thanks for the try
i just wonder if i can get ADB to work somehow - is it available in stock recovery?
my PC recognises the tablet, but states it is an MTP device and "adb devices" does not find anything... :-/
btw: it is reproducable, if i re-apply the ICS update, the TPT is boot-looping, after the 20seconds reset-thingy it just stays at lenovo screen - what does the 20seconds-reset do?
thanks 4 help

A similar function as the remove the battery. I've read in a thread to fix from loop problems.
This has helped me when I had a similar problem.

Instead of reinstalling ics why not go back to 2.5?

going back would require a working CWR and a nandroid-backup too, cause the lenovo updates are incremental only and have the version-checks in the update script :-(
the easiest solution would be a whole system image as signed update.zip, but lenovo does not provide anything like this...
i've never ever bricked any of my samsung devices, even in the most crappy situations i was able to flash back to the latest stock firmware with the images provided at samfirmware.com...
but i'm still hoping ...

Maybe something's missing?
Try to flash all 5 Updates available.

Wipe cache partition before each flashing and let it try booting between.
Last chance!
Problem is the missing ICS-Bootloader!

[Q] Boot Problem

I have a ViewPad running VegaBean Alpha 2and I've got a strange problem. The tablet boots at first boot, but when i reboot it or power it off and then on, it won't boot. It happend in VegaCream RC2 too. Is this a partition problem, or what? Is it any fix, or should I just install Honeycomb?

Use moddedstock version 1 as a base, boot to CWM recovery, wipe everything except the sd card, install vegabean from CWM.
It should be OK with moddedstock version 1 as the base.
Good luck
Backlight on, Won't boot and won't go into Recovery Mode
Hello all,
Has anyone else encountered this issue where the backlight comes at power up, but tablet won't boot, also won't go into recovery mode?
I am a basic user and have read the threads up and down all evening. Sorry, if this is an easy problem to fix, I just feel like an idiot. How do I enter recovery mode now. Tablet ran fine for three weeks and this is the very first time I have seen a problem.

Thanks!

The problem may lie the layout of the partition.
This is what's been written in the VegaBean thread:
"Before installing the ZIP file make sure that:
- You have the correct partition layout (if you have VegaCream installed, you have the correct layout)..."
Install VegaCream first with from this link:
http://www.mediafire.com/?z7r5zve13ay5qc6
It's installing through nvflash so you need to boot up in nvflash mode.
It formats the partitions to the right size, and VegaBean is based upon that layout.
After that you may just install VegaBean through CWM as usual, be sure to do a factory reset before you install it.
Hope this will help you!

Phone Bricked? Please help

So I rooted my RAZR M using motofail2go, and all was well.
Installed 'RAZR-M-Safestrap-3.12', as I was going to flash a custom ROM. I first backed up my Original Rom using the backup function.
I then wiped 'System', and went to flash the new ROM, but the flash did not work, so I restarted.
Now the problem is when the phone reboots, it showes the Safestrap splash screen with the Recovery option and start normal, but it is not working, as not sensing my inputs or something, after about 5 sec it goes to a blank screen and sits.
I tried to hard boot into the Android System Recovery, and tried to download an official Verizon ROM and install using 'apply update from external storage' using my micro sd, but I keep getting an error E:signature verification failed.
Does anyone know where I can find an official ROM to set it back to normal so I can use my phone again?
Thanks in advance.
Also: My phone originally had 4.0.4 version.

if you can get back into recovery, you should be able to press "restore" assuming you backed up your previous ROM.

What you might want to to is use RSDlite and flash that image you downloaded. This seems like it would help you, though I have not personally tried it:
http://www.andromods.com/tips-trick...oid-razr-m-xt907-stock-original-firmware.html
EDIT: And once the flash is complete, I would reboot into recovery again and wipe data and cache and then let it boot into the phone.
EDIT 2: Oh, and in addition to RSDLite, you will need the Motorola USB drivers so your computer can see the phone over USB.

[Q] Nexus 7 stuck on google screen boot

Yes i know. I ****ed up. But somehow i was tinkering and managed to delete the entire internal storage. I can still get into fast boot and.twrp. Can someone please help me?
What was i trying to fix? Check my other thread about the headphone jack.
Edit:Also. Twrp says i dont have an os above every swipe screen...
AW: [Q] Nexus 7 stuck on google screen boot
Have you tried reflashing stock?
Sent from my Nexus 7 running Android 4.2.1
If you have an OTG cable and a USB key you should be able to make ROMs or other backups which you preserved OFF THE TABLET available to TWRP.
If not, take the above poster's advice and install pure stock to copy stuff (ROMs, recovery images, etc) back on to the tab via MTP.
I too blew away all of /data once with that "format data" button in the touch version of TWRP; I feel your pain.
Um.....I may have made a mistake and swiped on all the clear screens...including internal memory...so...T_T Am i screwed???

You're not really screwed, you should be able to flash another ROM from recovery.
As long as you can get into fastboot, you'll be fine. The easiest way is to download and install Nexus Root Toolkit, then use the "back to stock" part to flash the factory image following the instruction.
I have got something even worse
My nexus 7 tab started freezing during use and then after booting in safe mode and wiping cache in recovery mode it now doesn't even go past the google screen. I haven't even flashed anything to it at all and it's showing these crazy symptoms (The bootloader is still locked and the device is not even rooted). I still have access to the adb sideload mode and fastboot but I am confused af as to what has happened
Any ideas guys?

[HELP] Bricked My U8800 [15Feb2013 Update]

Now, I dont usually open threads, but I have an issue here. I've searched and read a lot on how to recover the U8800 in case its soft-bricked, but I've tried the reflashing 2.2 method (Fails in about 5 seconds), Linux method (blefish's method, buzzcomp's method could not yield any results. I connected the phone in the bootloader mode (pink screen) to a Linux PC, but it doesnt appear as a new device there.
Then I tried to upgrade to 2.3, it installs fine, automatically enters recovery (formats data, cache etc), reboots a lot of times (bootloop?). So now whenever I on my phone, the Huawei logo just keeps flashing.
I've also tried to replace the files when connected in the pink screen by replacing the boot.img , recovery.img, amss.bin , EMMCBOOT.mbn file, yet it bootloops.
Prior to this, I had downgraded from Aurora to the stock 2.2, which worked fine. Then I replaced the stock recovery with CWM (the correct one, not the U8800 Pro's). I did the usual clearing of cache, data, formatted system, wiped dalvik cache in order for me to upgrade to a new ROM. Everything went downhill from there
UPDATE : I managed to get 2.3 to be installed. But everytime I enable "USB Debugging", upon the next reboot, there will be a lot of apps which closes unexpectedly, like the Huawei Launcher, Google Framework etc etc. I've tried B526 and B528, but everytime I have "USB Debugging" enabled, this happens. It works fine on 2.2 though
UPDATE 2 : After my fresh installation of the official 2.3, I'd changed the launcher to Holo Launcher, but it fails at starting up. If it does, it keep saying that Holo launcher has closed unexpectedly. The only way to fix it is to boot into recovery and wipe data.
Any help?

Where can i find the stock partition flash file?
I've found the original partition file from geno, flashed it then installed the official 2.3
everything seems fine, but if i change any settings like turning off fast boot, USB debugging, etc, the phone will bootloop.
UPDATE : I had fast boot disabled, booted in, and now I'm flooded by FC notifications....

[Q] Wiping didn't work, messed up restore - now can't boot into TWRP

First time flashing CM, and I may have messed up.
I rooted, installed TWRP, everything went perfect. I made a backup, and then tried to do a factory wipe. The wipe ended with the messages "unable to mount /system", "... /cache" and another one. I still tried to flash, and it just immediately got stuck, nothing happened. I rebooted, and everything worked fine. It was the Samsung stock image and all my apps were still there. I'm assuming it just didn't wipe at all.
I then went full retard mode, and tried to do a restore. I wanted to be sure my phone wouldn't fail on me in the recent future because some random stuff may have been partially wiped or something. Feel free to tell me I have the IQ of a chimp.
This completely messed things up, as it just got stuck at "Restoring System...". Eventually I restarted it with the power button. Now it can't boot normally, it can't boot into recovery mode, which just leaves download mode.
Any way I can fix this and subsequently install CM properly? I'm using TWRP 2.6.3.0. I've been told it's recommended to use 2.5, as the other version may have some issues (including not being able to recognize partitions). Only download mode still seems to work, so maybe there's a way to flash my phone back into the living world?
Versions:
Team Win Recovery Project 2.6.3.0
CyanogenMod 10.1.3 (RC2 jfltexx)
Thanks!
No idea really but maybe try to flash default rom/recovery etc with odin?
I've had this problem. Seeing as you only have download mode you have to flash a stock Rom and start again. Recoveries for our phone are still I development. Use official CMW to install CM, using links in Op.

I got the Samsung stock ROM of july, flashed it using download mode, and everything was back! I then rooted it again, and installed CMW (see versions below). I went into recovery, and tried to do a backup. It told me it failed: "Error while making a backup image of /data!". I then wondered if it may have been due to a lack of storage (which could very well be, as that was the issue before and the old backup by Teamwin was probably still on it somewhere), so I rebooted my phone. That's when it just failed and kept showing the Samsung logo at boot. I tried flashing my ROM again, again the logo. Then I did a factory reset using the regular recovery (cache and data reset), which fixed it. Now all my apps and data are gone, but that's no problem.
I'm back at the unrooted Samsung stock image now. Any ideas what I did wrong? These were the versions I used:
CF-Auto-Root-jflte-jfltexx-gti9505
i9505-cwm-recovery-6.0.3.2(0611)
Odin3 v3.07
I did nothing more than root, install CMW, try a backup and then it all went to ****. I'm surprised a backup can even do that.
Mmm I'm not too familiar with the internal workings of backups. Perhaps something was corrupted during flashing? Glad to hear that you have got your phone working again. There is an updated version of CMW somewhere in the original development thread.

i've had the exact same issue.
I did go back to stock firmware and recovery, rerooted(chainfire) and installed the latest CWM 6.0.3.6.
Then, i did download Jamals Google play 4.3 rom, placed it on my SDcard and did follow the instructions. Works like a charm, and i've got noe clue what happened to my phone. however, it works now.

I tried CMW 6.0.3.6 and the Google Play 4.3 ROM as you said, and it works perfectly! I didn't try a backup this time, as it didn't exactly have anything to back up anymore.
Finally my precious vanilla Android again, I missed it since I switched from my Galaxy Nexus to my S4. Thanks a lot guys!
Edit: I do seem to be having one issue. Quite frequently after it's booted, and I enter the SIM pin, the message "Unlocking SIM card..." stays there indefinitely. I can use the phone but the message covers everything up. This doesn't always happen, but quite often. I've read some ROMs can't handle SIM lock, like CM. This is a Google Play edition, however. Is it normal that this doesn't work?
I can seem to fix it by holding the power button, and choosing "Unlock SIM" from the menu. I guess it's not that bad as I don't often reboot my phone.
