[Q] Xperia Tablet Z Recovery Issue - Xperia Tablet Z Q&A, Help & Troubleshooting

Hello!
I've just finished following the guide http://forum.xda-developers.com/showthread.php?t=2295694
It has definitely flashed the recovery, which is great.
However I cannot boot the recovery using any kind of key combination.
The only way I have found to access it is by booting into the current stock ROM, and using the CWM ROM Manager.
My issue is that if I want to flash a different ROM (AOKP when I figure this out), if the ROM fails and won't boot, I can't get back into recovery to fix the issue or re-flash a different ROM.
I don't want to end up with a bricked device.
I've done a lot of reading and it seems like a common issue, but no real solutions
I'm more used to flashing Samsung devices
Thanks for any assists!

[Q] Recovery img flashing (Stock 2.1 rom)

Hi,
Due to HTC's special touches, the recovery image doesnt stay flashed, and on normal boot its flashed over (meaning if i try to go to recovery after a normal boot, i get the red triangle stuff, and have to pull the battery). I was wondering if this would potentially cause troubles if i was trying to flash a custom ROM from recovery? in other notes, i do find sometimes i have to pull the battery 4 or 5 times to get it to normally boot (thats without holding the buttons >.>).
Thanks in advance.
HTC HERO recovery image flashing problems
I am having exactly the same problem!
I did a quite a bit of research on how to root, backup and flash my HERO and every guide I found describes the process using Universal AndRoot + Rom Manager and it seems there should be no problems. I already rooted my phone successfully, installed Rom Manager and flashed either ClockworkMod 2.5.0.1 or RA Recovery 1.7.0.1 which are able to boot but only once. The next time I reboot I get the red triangle warning and it loads into stock recovery (by pressing vol_up + powroff buttons), so the custom recovery lasts only one boot cycle. I was able to backup but I don't want to risk to wipe and flash since there is a chance it might stuck in the bootscreen loop afterwards and I won't be able to do anything.
There is a thing with s-off and SPrecovery which helps to resolve the problem but it doesn't look like there is anything for HERO.
Any help would be appreciated.
ps I tried to manually flash recovery from inside the phone and from windows command line with the same result.
forum.cyanogenmod.com/topic/8182-how-to-root-your-hero
posted some similar comments over there, and the only init script that i can find when in recovery.
Yeah I posted my question there too.
I was able to find some information about the issue (he is talking about Villain ROM but I think it doesn't really matter):
pulser_g2:
Repeat the process again, as I think stock ROMs try and overwrite the recovery each time they boot. When you finish the process, immediately nandroid and flash VR12. That will then flash a new recovery, AmonRA 1.6.2a, and you will be sorted
Click to expand...
Click to collapse
So it looks like we should just go ahead and flash a custom rom which, in theory, will eliminate the problem.
yeah was tempted to just flash, but sending duck my system img for him to dissect anyway.
yeah worked fine, running cm6.1 now
Yeah once you root you have to flash a custom rom before reboot or u loose the root
I learnt it after lots of reboots and re roots.
but now I wanted to know if I could save the original rom which i have as nand backup to make as an update.zip like custom rom for safe keepimg
I flashed CM6.1 -based TastyFroyo 1.2 and I can confirm custom recovery stays flashed now.

How do I get stock recovery back??

I have ClockworkMod 5.5.0.4 currently installed, when I reboot into recovery mode, the menu scrolls by really fast on an endless loop, and I cannot select anything.. So I was wondering how I would get the stock recovery back onto my tab.. Any help is much appreciated.. Thanks
I think you got the rolling CWM issue:
Look over here: http://forum.xda-developers.com/showthread.php?t=1555984
I'm now at 4.0.4 and have the hc stock recovery somewhere.
Whithout knowing that ics has the same recovery than hc exactly, and I'm not convinced that it is so, don't think it helps you much.
But the above Link could help you way better.
edit1:
i had same issue with CWM 5.5.0.4, flashed a different bootlaoder and it worked...BUT if you then recover back to hc for example you get strange behavior here... just tbh
the best way is to flash the entire firmware on the tab. And obviously the more destructive one too.
I suggest you also to install the cwm recovery 5.5.0.4. That's the only non-rolling recovery you will find, and to do that it's not necessary to reinstall the stock one
here's the link to the good recovery for you: http://www.teamovercome.net/p7500/?page_id=8.
If you're already using this and still have the rolling screen, the problem is the bootloader: so follow this post http://forum.xda-developers.com/showpost.php?p=27830023&postcount=41 and your recovery should be fine.
If the problem still goes on, problably you did a little bit mess flashing roms and recoverys and in that case your only solution is to flash the entire stock firmware erasing all the old stuff and then reinstall cwm, root the device and so on.
Thanks for all your help guys I will give it a shot..

[Q] HTC Stock ROM, custom recovery, factory reset related

Hello there,
Need Help on urgent basis. I am still using HTC Explorer . I need Help with multiple things.
I was on custom rom with Philz Touch recovery. My phone started to do some issues with soft keys. I Tried some other ROM but nothing changed. I reverted back to the same ROM and then even my touch started to mess up.
I did restore of my old Stock ROM. (Backup I did before installing Custom ROM)
Now my touch is much better and soft keys are working much better.
I want to do a factory reset on stock ROM to see if can get rid of this soft key and touch issue because reverting back to stock ROM did a good job in almost solving my issue now my questions are:
1. Stock ROM but custom recovery (Philz Touch Recovery) is it possible to do factory reset in this situation or I have to revert back to stock recovery?
2. I am facing issue with fastboot my phone does not connect in fastboot mode it does shows Fastboot USB but on my computer it says Waiting for device need help with this too.
3. If anyone knows about the method to flash stock recovery without using PC then kindly do let me know.
4. I am using Stock ROM backup. ROM which came already installed on my device. Do I need to download RUU or it is just fine to do factory reset on this ROM.
Reply as fast as you can guys because I have only this one phone to use and I am tired of trying alot of things now I just want to do factory reset and then start over again.
Regards,
Usman Aly

[Q] HELP - Stock Recovery Damaged?

All -
I have a Xperia Z Ultra GPe, bootloader unlocked.
I have been experimenting flashing with different builds of Cyanogenmod.
I was able to get into the Cyanogen Recovery AND Stock Recovery.
Then I was getting random "Process.acore" errors from time to time, and only resetting the phone would resolve which prompted me to flash another Kernel. After a failed flash, now I do not seem to be able to get into stock recovery anymore.
Currently the phone is on Cyanogenmod Build CM12 20150401 which I found is relatively more stable than others.
I can get into the bootloader, then when I switch to 'Recovery Mode", the led will flash once and the phone will just shut down.
I can still get into Cyanogen Recovery without any issues.
Questions are:
1. How do I fix the stock recovery? Do I need to flash another Kernel?
2. When I tried to go back to stock rom, it complained about "Signature verification failed" and would not continue. What caused that?
3. The Cyanogen Recovery functionalities are very limited. Can I flash CWM or TWRP while still using Cyanogenmod ROM?
4. I was getting "Process.Acore" error very often (about every 3-4 weeks). Does anyone who is on the stock 5.0 LP have this issue? Is that the best solution for a reliable ZU at this point? Please advise.
Thank you in advance!

Gt-i9100 stuck on startup logo

Hello everyone,
I own a samsung galaxy s2 gt-i9100 I've been using it for a long time. A few days ago i installed cynogenmod 13 marshmallow on it but faced some severe issues like dialler problems,battery drain,google play services not working. So, i switched it back to my previous rom i.e. cm 12.1 lollipop but my old twrp recovery got replaced by cynogenmod default recovery. Now some people who may have used it know that its very basic and does not has backup,restore, has bugs,does not flashes some zips or files that i wanted so i tried to replace it with twrp/cwm through rashr,flashify,rom manager,etc. But none of it worked, whenever I'd boot after flashing the twrp/cwm recovery it'll go back to the default cynogenmod recovery. Now, me not knowing what im doing stupidly downloaded mobile odin lite app then i downloaded the cwm kernel recovery kitkat compatible and installed via mobile odin lite. After that it got screwed, it won't just startup it'll just start and go into recovery i mean continuously! It was annoying, then i read an article on a forum to download any cm nightly or stable mod and flash it but i did a little bit of tweak of removing the recovery boot img file with twrp to get preinstalled twrp recovery but i gotta admit it was the last mistake possible. Now i sit here, with a bricked phone in my hand which is looping continuously only on the samsung logo. If anyone out there can assist me correctly it'll be a life saver for me. Thanks for reading this and please reply with a solution asap. Please! Im in danger!
can you get into download mode?
if yes you can download a stock firmware and flash but you will have to hope it will work, otherwise you will get stuck on nand write start which means the nand is stuffed/corrupted and then basically only a motherboard replacement will do the job, or you can try using another computer, reinstall usb drivers..
can you get into recovery mode?
if you can, you can flash a rom
The 'nand stuffed' assumption is a last resort, tried everything and nothing works assumption. There is *plenty* to try before assuming that the nand is 'stuffed'......
It sounds like (from your description) that you may have rendered recovery useless and inaccessible.
I've a feeling what you need to do is to go into download mode and Odin flash a firmware.
Even if it doesn't boot, you should have a recovery that you can flash PhilZ recovery from and then use that to flash a custom rom. Initially, I'd stay away from the MM builds and instead flash something KK or LP based as they're less 'volatile' and have a higher degree of stability than the MM roms.
