Need some help stuck in bootloop after a flash SGP311 - Xperia Tablet Z Q&A, Help & Troubleshooting

I was using Resurrection Remix 6.0.1 for a while, then I decided to try out the official [OFFICIAL 5.1.1] Rooted 10.7.A.0.228. that's where my bootloop problem started. I tried to flash 2 separate stock firmware 4.4.2 and 5.0.2 but I'm still stuck on bootloop with both of those. I'm a beginner at at all this stuff so I really am not sure what it is I need to do to get out of the bootloops. Hope you guys can help me out Thanks.

I had some bootloops but I manged to recover, but first of all: do you have an unlocked bootloader?
If yes then try to flash TWRP, once you have TWRP you should easily be able to install any ROM

Thanks for the reply, and sorry mine took so long. I tried flashing TWRP like you suggested and I was able flash another rom like you said thanks a lot for the help. I was kind of worried for a while.

[Q] Question regarding stock roms / flashing

Hello,
Long time reader here. I finally made an account recently because I finally wanted to Root my phone and mess around with Cyanogenmod.
My question is this: I have an unlocked, unbranded Samsung GT-i9300 that I purchased from Newegg back in the summer time and I have still yet to receive any sort of update (still on 4.0.4). Can someone explain to me the whole stock updates scenario? I would have thought buying an unlocked, unbranded phone I would have at least gotten updates faster than the Verizon S3. Now.. I know I can flash Cyanogenmod and be done with it. Which I have which leads me to the last question. What happens if I flash my phone with the 4.1.2 stock rom that was just released in Poland recently? Will it work? Why wouldn't it? Does the baseband really matter as far as compatibility? (PDA? CSC?)
Thank you for your time.
I answered my own questions. Thanks for looking
I was so excited I forgot to elaborate a little.
I was successfully able to root my phone using cf root / odin, install clockworkmod recovery, install cyanogenmod 10 then re-flash back to stock using triangleaway, and a stock rom from samsung firmware using odin.
I had thought I bricked my phone when it was in an endless loop on the splash screen but I was able to get into android recovery mod and do a format/wipe/clean cache. *phew*

[Q] How do I remove Cyanogenmod 11.0 & install this custom ROM

Hi there,
I'm sorry if this has been covered before in another thread but after searching with limited success I have been unable to find a detailed answer, perhaps I'm just a little bit dim & have missed something however.
QUESTION:
After installing CyanogenMod 11.0 [KitKat][4.4.2] by "Gava97" I have found that it is simply not for me. I would very much like to install Destro316's "Proformance" ROM [4.0.4] http://forum.xda-developers.com/xpe...m-4-0-4-proformance-rom-long-battery-t2547481 as it seems much more stable having been based on a stock Sony ROM.
Do I just flash the new ROM over the previous one? Do I return to a stock setup & redo the rooting process? If so, how?
Being extremely new at this android thing, I'm a little stumped as to how to proceed. All instructions seem too vague for me to confidently follow without bricking something. As I said, it may just be that I'm a missing something.
Phone was originally running [2.3.7] when I bought it, though I soon flashed to stock Sony ICS [4.0.4] Firmware version 6.1.1.B.1.100.
I unlocked my bootloader, rooted & installed Clockwordmod Recovery via this tutorial: www(dot)youtube(dot)com/watch?v=V232-3tZddE
I would be very grateful if anyone could fill me in with a step-by-step guide on removing all traces of CyanogenMod & installing this new ROM. Any suggestions for different ROM's are welcome as well, of course.
-----
Bootloader unlocked: Yes
Root: Yes
Clockworkmod Recovery: Yes
Kernel version: Transcendence v 1.1.6
Flashtool Version: 0.9.14.0
PC: Windows 7

I really am sorry if I missed something in my search, I'm very new at this.
I appreciate anyone taking the time to read this & help me out.
Cheers,
Miles

Just follow the instructions on the ROM threat, this is erasing your CM 11, then install your ROM through CWM.
Good luck!
U could Just follow the instructions that included at the ROM u want, that will eras your CM 11, then install the ROM U want through CWM.
Clean Install is required
Woops
Hi everyone!
Sorry for the late update.
So I attempted to follow the instructions outlined in the new rom I was attempting to install and it did nothing. Absolutely nothing. Phone continued to boot into Cyanogenmod 11 kitkat as if nothing had happened.
Now obviously I messed something up, but I needed a properly functioning phone for work asap so I bought an Xperia Z1 Compact just to be done with it. Over the hassle.
However it's been bothering me that I still have a basically pristine Xperia U minus it's software tantrum.
So, how do I go about restoring this phone to the factory Gingerbread and removing Cyanogenmod?
Baby steps please.

I'm by no means an expert.
I follow the guidelines here to flash my Xperia Sola from ICS to a Kitkat rom.
http://forum.xda-developers.com/xperia-u/issues/getting-startedrooting-bootloader-t2100529
I'm not entirely sure but downgrading should be similar? Fastboot (via flashtool) and flash boot.img. Then in recovery mode, flash the stock Gingerbread rom?

Issues returning to a custom stock rom after flashing aosp rom

Hey guys,
I assume that someone has previously posted a thread about this issue but my attempts to reach any have proved pointless.
Therefore I hope someone could just enlighten me as to what I could do to solve this issue.
I flashed this aosp rom on my Galaxy SIII (I9300 international) but I decided to go back to the custom stock rom I was previously using but when I tried to restore my backup the phone got stuck in bootloop in the samsung loading screen.
Thus, I tried to flash a new custom rom from the ground up the the phone is still behaving the same way.
Can someone help out, please?
Thanks in advance!
Cheers!
I would advise you to use this rom (its build on touchwhizz but with many improvements)
http://forum.xda-developers.com/galaxy-s3/development/rom-neatromlite-themed-aroma-mods-t2060403
Just be sure to select the right one

Use Odin to return your phone to official stock... if stuck in bootloop after flashing boot into recovery and factory reset.Once you have your phone up and running then you can go back to flashing a custom rom.

Actually, all that's needed is modem.img from the KDZ for the WiFi to work. Also normal flash should do it too.
Sent from my D620r [Stock 4.4.2 , -V- Kernel]
:good::good:
it's ok
Upload the screen shots.
Can I flash this with twrp recovery over stock kk?
D620r lolipop
When flashed via TWRP it works wifi, but not GSM. When flashed via KDZ, everything works.
Boot loop
I have a d620 that came with a v10e firmware. Two nights ago my phone updated to the 5.0.2 and I got stucked on the lg logo. Fortunately I've managed to flash it back using the stock rom. I really want to update to lollipop and I was wondering if any of you guys know how to get around the bootloop problem.

D618 V20b lollipop BUG on COC
is there any bug on COC graphic failures on war logs and etc.? on clash of clans?
im using the stock-rom lollipop - CIS version and the bug on the COC game.
you have Screen wake up notifications with Glimpse Notifications from google play, for all lg g2 mini. perfect.
I've flashed the zip on my d620r, everything works great. There are no bugs, battery life is very good compared with KitKat 4.4.2, and smoother overall. Great job!
Upgrade from V10g to V20a keeping data
First of all, thanks to all putting effort into this development.
I own a D620r with software V10g and KitKat 4.4.2, unlocked bootloader and TWRP. I used towelroot to root it. Everything runs fine so far.
I got a notification for the official OTA update to V20a and downloaded it to the device. I tried to apply it but were stuck in a recovery loop. I learned that official OTA updates need stock recovery and I cannot apply them having TWRP installed. I applied this fix to escape from recovery loop. The device is alive again, but the LG updater app asks to apply the downloaded update once a day.
Now I found this thread. The phone is my main device and contains lots of apps and settings. I want to keep the data if possible.
A) Do I have to expect trouble when I flash the V20a from this thread without wiping the data partition?
B.1) Or would the following procedure be an alternative:
Flash stock recovery (I made a backup using Rashr)
Revert bootloader to original locked aboot
Apply OTA update
Root
Replace bootloader with the unlocked one
Flash TWRP
B.2) I read that towelroot is based on a security vulnerability of the linux kernel that is fixed with Lollipop . If that is true, can someone give a hint how to root on Lollipop?
C) Can I choose between V20c/D620 and V20a/D620r or do they belong to different devices and are incompatible?
Thanks for your time reading this post.
Thanks
Thank you for the Rom and the instructions. It works great, there are no functions that are not working.
It also solves the bug for the smartwatches that caused battery drains on Kitkat.
when a version with xposed???

Never, because this is the stock rom in a flashable .zip for custom recovery.
And xposed for android 5 ist still alpha and doesn't work correct on our phone.
If you want to try xposed you can just install it.
Read the xposed thread for that.
Please don't ask any further questions about xposed here, this thread is only about zip flashable stock rom.
Thank you.

What does it mean?
EDIT:
Also one more question, can I update my phone OTA in case there is a new software?
